Description

FIELD OF THE INVENTION The present invention relates to a woodgrain painting tool.

There is a high demand for the texture of wood in interiors. For this reason, it has traditionally been common to use wood for decorative interior walls of buildings.
However, when using actual wood, for example, a single board longer than 10 meters may be difficult to transport into a building, deliver to a purchaser, or install indoors due to its size. There are many.

Furthermore, the use of actual wood for interior decoration accelerates the depletion of forest resources, and is also undesirable from the perspective of environmental protection. In particular, the use of wood goes against current social trends that call for a sustainable society.

For this reason, it is widely used to replace the actual wood with a material whose surface is covered with a film that imitates wood. For example, what is shown in Patent Document 1 attempts to give the interior a wood texture by applying woodgrain wallpaper to the interior walls.
However, manufacturing the wood grain pattern film shown in Patent Document 1 is time-consuming and repair is not easy.

The inventor of the present invention created the above-mentioned one-piece board by applying paint to the wallpaper with a brush, drawing wood grain on the wallpaper to form a wood-grain wallpaper, and pasting the wallpaper onto an interior surface. We considered making it easier to transport, deliver, and install indoors.
During the above study, it was found that simply applying paint to wallpaper using a conventional brush does not allow efficient wood grain formation, and that the quality of the wood grain pattern created varies depending on the skill level of the operator. That's what I found out.

On the other hand, in order to solve the above problems of Patent Document 1, Patent Document 2 proposes a method of forming a wood grain pattern on the surface of a member to be coated by applying a paint.
What is shown in Patent Document 2 is to apply a first paint of a color that is the base tone of a wood grain pattern to the surface of a member to be coated, and to apply the above-mentioned paint to the surface of the member to be coated coated with this first paint. Applying a second paint that is a different color from the first paint and diluted with a solvent from 100 times to 2000 times more than the first paint using a brush with scattered bristles that are coarse and dense. In this coating method, a wood grain pattern is formed on the surface of the member to be coated with the first paint.

What is disclosed in Patent Document 2 mentioned above proposes forming a wood grain pattern by using two types of paints, and the wood grain pattern is created by applying each of the above paints using a brush. It is formed on the surface of a metal plate that is a member to be painted.
It is conceivable that the above-mentioned member to be painted in Patent Document 2 could be used as wallpaper to form a wood grain pattern by applying paint, making it easier to transport it into a building, deliver it to a purchaser, or install it indoors. , the method shown in Patent Document 2 only applies paint using a conventional brush, and does not enable the efficient and simple application of a wood grain pattern using a brush.

Embodiments of the present invention will be described below based on the drawings.
(overview)
This woodgrain painting tool is capable of simultaneously drawing lines with two brushes on a surface to be coated with paint, such as wallpaper.
That is, this woodgrain painting tool includes a rod-shaped body 1, two brushes 2 provided on the rod-shaped body 1, two operating sections 3 for operating each of the brushes 2, and a guide for operations by the operating sections 3. A slider 4 and an elastic body 5 are provided (FIGS. 1 to 3(A), FIG. 4).
The configuration of each part will be explained in order.

(rod-shaped body 1)
The rod-shaped body 1 is a hollow pipe. The rod-shaped body 1 can be made of plastic, wood, or metal, and is not limited to any material; however, in this example, aluminum is used in terms of durability and light weight. A pipe was used.
Moreover, the rod-shaped body 1 was made into a pipe by combining half cylinders 11 and 12, which are obtained by cutting the cylinder in half, and fixing them together with a connector 13 (FIG. 2). For the connector 13, well-known screws, pins, bolts, and nuts may be used. In this example, the connector 13 is composed of a bolt and a nut. The connector 13 is provided in the rod-shaped body 1 at a position where it does not interfere with the operation of the operating section 3, which will be described later.

A bolt of the connector 13 passes through the half cylinders 11, 12 vertically at approximately the center in the longitudinal direction of the half cylinders 11, 12. In the example shown in FIG. 2, the connectors 13 are provided at two locations on the left and right sides of the center of the rod-shaped body 1, but the connectors 13 are not limited to the two locations at the center. The bolts and nuts may be installed at three or more locations, such as near the left and right ends of the body 1, or by using a cylindrical handle 10, which will be described later, as a connector, the bolts and nuts can be attached to the center one. It may also be implemented without providing the connectors 13 such as the bolts and nuts mentioned above.

A handle 10 is provided at each end of the rod-shaped body 1. Operator m can hold the woodgrain painting tool by grasping the handle 10 with hand h (FIGS. 3(A) and 4).
The handle 10 is a cylindrical member (FIGS. 1 and 2), and is fitted onto the outer peripheral surface of both ends of the rod-shaped body 1. The handle 10 is preferably made of a material with high frictional resistance, such as rubber or urethane, which does not easily slip when gripped. The handle 10 may be made of a highly elastic material such as the above-mentioned rubber or urethane, and may be forcibly fitted to both ends of the rod-shaped body 1.

The handle 10 is not limited to attaching a member formed separately from the rod-shaped body 1 to the rod-shaped body 1 as described above, but the handle 10 can also be formed by using the outer circumferential surface of both ends of the rod-shaped body 1 itself. good. However, it is appropriate that the surface of the handle 10 has a relatively high frictional resistance to make it difficult to slip, and it is preferable to provide a member made of a material having a high frictional resistance such as the above-mentioned rubber or urethane.
In addition, by forming the handle 10 from a material with high adhesive elasticity such as the above-mentioned rubber or urethane, and forcibly fitting it to the rod-shaped body 1, the half-tube 11, 12 can be more securely connected to each other.
Hereinafter, the handle 10 held by the left hand h will be referred to as the left handle 10, and the handle 10 held by the right hand h will be referred to as the right handle 10, as required (FIG. 3(A)).

A guide hole 14 for guiding the operation of the operating section 3 is provided on the side surface of the rod-like body 1, that is, on the lower surface of the horizontal rod-like body 1 (the horizontal direction is the longitudinal direction) (FIGS. 1(B) to (B)). D), Figure 2). The guide hole 14 is a slit extending in the longitudinal direction of the rod-shaped body 1 (hereinafter referred to as slit 14 as needed). In this example, among the half cylinders 11 and 12, one 11 is the upper half cylinder 11 and the other 12 is the lower half cylinder 12, and the lower half cylinder 12 is disposed below the upper half cylinder 11.

The slit 14 is a through hole provided in the lower half cylinder 12 and extending in the longitudinal direction of the lower half cylinder 12, and vertically passes through the horizontal lower half cylinder 12.
The bolt of the connector 13 is passed through the upper half cylinder 11 and the lower half cylinder 12 which are made horizontal at a position different from the slit 14 in the hand direction of the rod-shaped body 1, and extends vertically. The nut of the connector 13 is screwed into the tip of the bolt of the connector 13, so that the upper half cylinder 11 and the lower half cylinder 12 are integrated.

In this woodgrain painting tool, the outer diameter of the rod-shaped body 1 is 1 cm to 3 cm, the distance t between both handles 10 is 20 cm to 60 cm, the length of the handle 10 in the axial direction is 5 cm to 20 cm, and the handle Preferably, the outer diameter of 10 does not exceed 4 cm. However, even if dimensions deviate from the above-mentioned numerical range, such deviating dimensions are not excluded as long as it is possible to appropriately paint a wood grain pattern.
Furthermore, assuming that the longitudinal direction of the rod-shaped body 1 is the left-right direction, the slits 14 are provided at two locations on the left and right adjacent to each of the two handles 10 on the left and right. The length of the slit 14 (in the longitudinal direction of the rod-shaped body 1) may be any length as long as it can cover the sliding range of the slider 4, which will be described later.

(brush 2)
Each of the brushes 2 includes a rod-shaped body 20 and a bristle bundle 21 provided at the tip (lower end) of the body 20. The brush 2 is used to impregnate at least the tips 22 of the bristles 21 with paint and apply the paint to the surface to be coated with the paint. A commercially available brush can be used as the brush 2.
Each of the brushes 2 is attached to the rod-shaped body 1 between the handles 10. One brush 2 is provided closer to one handle 10, and the other brush 2 is arranged closer to the other handle 10. If necessary, the brush 10 closer to the left handle 10 will be referred to as the left brush 10, and the brush 10 closer to the right handle 10 will be referred to as the right brush 10.
The brushes 2 each extend in a direction intersecting the longitudinal direction of the rod-shaped body 1 with a space between them, with the surface to be applied with the paint being horizontal. By gripping the rod-shaped body 1 and making it substantially horizontal, the bristles 22 of both brushes 2 can be directed downward.

In this example, the brush 2 is attached to the rod-shaped body 1 via the operating section 3. The tip of the brush 2, that is, the tip of the bristle bundle 21 is directed downward, and the rear end (upper end) of the body 20 of the brush 2 is fixed to the operating section 3 provided on the lower surface side of the horizontal rod-shaped body 1. This fixed structure will be detailed later.
In this example, the bristle bundles 21 of each brush 2 are flatly bundled, and in the above-mentioned fixing, the width direction (radial direction) of the maximum width (maximum diameter r) of the bundle tip (bristle tip 22) of the bristle bundle 21 is , is attached to the operating section 3 along the longitudinal direction (left-right direction) of the rod-shaped body 1.

(Operation unit 3)
The pair of operation parts 3 are arranged between the left and right handles 10 of the horizontal rod-shaped body 1.
One operating section 3 is arranged near the left handle 10, and the other operating section 3 is arranged near the right handle 10. For convenience of explanation, the operating section 3 disposed near the left handle 10 will be referred to as the left operating section 3a, and the operating section 3 disposed near the right handle 10 will be referred to as the right operating section 3b (FIG. 3(A)). . It should be noted that it is not fixed whether each of the handles 10 is gripped with the right or left hand; if the handle is gripped with the left hand, it is the left handle 10, and if it is gripped with the right hand, it is the right handle 10. Therefore, regarding the operating section 3, the operating section 3 that is operated with the left hand by grasping the handle 10 as necessary is called the left operating section 3a, and the operating section 3 that is operated with the right hand is called the right operating section 3b.

Each of the left operating section 3a and the right operating section 3b is a lever on which the thumb f of the hand h holding the handle 10 can be hung. The thumb f of the left hand h is placed on the right surface of the left operating section 3a (the surface facing the right operating section 3b), and the thumb of the right hand is placed on the left surface of the right operating section 3b (the surface facing the left operating section 3a). In this example, by pulling the operating portion 3 with the pad of the thumb f against the bias of the elastic body 5, which will be described in detail later, the brush 2 can be slid and the distance between the two brushes 2 can be widened.
In this example, each of the left operating section 3a and the right operating section 3b is a plastic molded product formed in a substantially rectangular parallelepiped shape, and is arranged with its longitudinal axis horizontally along the lower surface of the horizontal rod-shaped body 1. . It is preferable that the upper surface of each of the substantially rectangular parallelepiped-shaped left operating section 3a and right operating section 3b be a concave curved surface to match the lower surface of the rod-shaped body 1.

The operating portion 3, that is, the left operating portion 3a and the right operating portion 3b, are arranged directly below each of the slits 14 of the rod-shaped body 1 (FIGS. 1(B) to (D), FIG. 2). That is, the left operating part 3a is arranged directly below the slit (left slit) 14 adjacent to the left handle 10, and the right operating part 3a is arranged directly below the slit (right slit) 14 adjacent to the right handle 10. .
The left slit 14 extends from near the left handle 10 to near the center of the rod-shaped body 1 in the longitudinal direction. The right slit 14 extends from near the right handle 10 to near the center of the rod-shaped body 1 in the longitudinal direction.
The left slit 14 is made to be equal to or longer than the (average) length of the thumb f of the left hand h that grips the left handle 10, extending at least along the longitudinal direction of the rod-shaped body 1. The right slit 14 is made to be equal to or longer than the (average) length of the thumb f of the right hand h that grips the right handle 10, extending at least along the longitudinal direction of the rod-shaped body 1.

(Slider 4)
Two sliders 4 are accommodated in the internal space of the rod-shaped body 1 .
The slider 4 can slide along the longitudinal direction of the rod-shaped body 1 within the internal space.
One of the sliders 4 (left slider 4) is placed directly above the left slit 14, and the other slider 4 (right slider 4) is placed directly above the right slit 14. Ru.
Each slider 4 is formed into a substantially cylindrical shape, and in this example is a plastic molded product.

The left slider 4 in the rod-shaped body 1 and the left operating part 3a arranged on the outer peripheral surface of the rod-shaped body 1 are connected by a connecting member 7 (left connecting member 7) inserted through the left slit 14, By operating the part 3a with the thumb f of the left hand h, the left brush 2 is moved along the rod-shaped body 1, and the left slider 4 is slid inside the rod-shaped body 1 along the longitudinal direction of the rod-shaped body 1. By doing so, the left slider 4 guides the movement of the left brush 2 along the rod-shaped body 1. Therefore, the left slit 14 has a length that at least covers the sliding (movable) range of the left connecting member 7.

The right slider 4 in the rod-shaped body 1 and the right operating part 3b arranged on the outer circumferential surface of the rod-shaped body 1 are also connected by a connecting member 7 (right connecting member 7) inserted through the right slit 14, and the right operating part 3b is connected to the right slider 4 in the rod-shaped body 1. By operating the part 3b with the thumb f of the right hand h, the right brush 2 is moved along the rod-shaped body 1, and the right slider 4 is slid inside the rod-shaped body 1 along the longitudinal direction of the rod-shaped body 1. By doing so, the right slider 4 guides the movement of the right brush 2 along the rod-shaped body 1. Therefore, the right slit 14 has a length that at least covers the sliding (movable) range of the right connecting member 7.

When assembling the wood grain painting equipment, before combining the upper and lower half cylinders 11 and 12 to form the rod-shaped body 1, each of the sliders 4 is placed on the slit 14 in the lower half cylinder 12, and the sliding The connecting member 7 may be passed through the child 4 and the operating section 3. In this example, the connecting member 7 is a screw, and the head of the screw is arranged on the upper surface of the slider 4, and the tip side of the screw is penetrated into the slider 4 and the operating part 3, and the screw is By screwing the male screw provided on the tip side into the upper end of the body 20 of the brush 2, the slider 4 and the operating section 3 are connected, and the brush 2 is also integrated with the slider 4 and the operating section 3. do.

However, the brush 2 may be fixed to the operating section 3 by a known fixing means other than the slider 4 and the operating section 3 (not shown). For example, it is assumed that the tip of the screw, which is the connecting member 7, is fixed inside the operating section 3, and that a hole is provided in the lower surface of the operating section 3, and the upper end of the body section 20 of the brush 2 is forcibly fitted into the hole. Alternatively, the body portion 20 of the brush 2 may be fixed to the operating portion 3 with adhesive or other screws.

As mentioned above, when fixing the brush 2 to the operating section 3 using a fixing means different from the connecting member 7, the connecting member 7 is limited to the above-mentioned screws also when connecting the slider 4 and the operating section 3. isn't it. For example, a convex portion protruding to the lower surface of the slider 4 may be provided as the connecting member 7, a recessed portion may be provided on the upper surface of the operating portion 3, and the tip of the convex portion may be forcibly fitted into the recessed portion, or an adhesive may be used to The convex portion may be fixed to the concave portion (not shown). Also. The lower surface of the slider 4 may be provided with the recessed portion, and the upper surface of the operating portion 3 may be provided with the convex portion. Further, both the lower surface of the slider 4 and the upper surface of the operating section 3 are provided with the above-mentioned recesses, and the slider 4 and the rod-shaped member separate from the operating section 3 are fixed into both recesses by force fitting or with adhesive. It can also be used as a thing.

When using a commercially available ready-made product as the brush 2, the brush 2 is not directly connected to the connecting member 7, but a plastic cap (not shown) that opens downward is attached to the connecting member 7. The brush 2 may be fixed to the operation part 3 by forcibly fitting the cap to the rear end of the brush 2, that is, the upper end of the body 20. In this case, The brush 2 can be replaced by pulling it out from the cap and fitting another brush 2 into the cap.
Further, as described above, the brush 3 may be fixed directly to the operation part 3 formed separately from the brush 2 using the connecting member 7 or indirectly via the cap, but the brush 3 may not be made into a ready-made product. The operation section 3 may be formed on the body 20 of the brush 2, that is, the body 20 may include a portion shaped as the operation section 3.

(Elastic body 5)
The elastic body 5 has elasticity and always urges the slider 4 as a biasing portion. In this example, two elastic bodies 5 are provided in accordance with the number of sliders 4.
When the operating section 3 is not receiving any force, that is, when the operator m is not operating the operating section 3, the above-mentioned biasing force on the slider 4 of the elastic body 5 causes the operating section 3 to maintain a constant position relative to the rod-shaped member 1. placed in position. When the operator m is not operating the operating section 3, the brush 2 integrated with the operating section 3 is placed at a fixed position with respect to the rod-shaped body 1.
The above-mentioned fixed position is within the reach of the thumb f of the hand h holding the handle 10. Specifically, it is preferable that the distance v between the handshake 10 and the operation surface of the operation unit 3 disposed near the handshake 10, that is, the surface to be pressed with the thumb f, does not exceed 7 cm. However, even if the distance v exceeds 7 cm, this does not preclude implementation with the distance v as long as the operating section 3 can be operated smoothly.
In this example, the elastic body 5 is a push spring, and by pushing the elastic body 5 toward the handle 10 with the pad of the thumb f against the bias of the spring, the brush 2 is moved while compressing the spring. You can widen the spacing between.

In the internal space of the rod-shaped body 1, a pressing member 6 is provided closer to the end of the rod-shaped body 1 than the slit 14 in which the slider 4 is located in the longitudinal direction of the rod-shaped body 1. Specifically, on the inner circumferential surface of the rod-shaped body 1, which is a pipe, there is a pressing member 6 (left pressing member 6) on the left side of the left slider 4 (towards the left handle 10) in the longitudinal direction of the rod-shaped body 1. A pressing member 6 (right pressing member 6) is also provided on the right side of the right slider 4 (on the right handle 10 side). The left and right pressing members 6 are both small pieces that protrude from the inner circumferential surface of the rod-shaped body 1 toward the radially inner side of the rod-shaped body 1, and are fixed to the rod-shaped body 1 with a fixture 15. As the fixture 15, well-known fixtures such as bolts, nuts, and screws can be used. In this example, the fixtures 15 are bolts and nuts. Note that the rod-shaped body 1 may be formed of iron, and the fixture 15 may be attached to the rod-shaped body 1 by welding.
Strictly speaking, the biasing section is composed of the elastic body 5 and the pressing member 6 in this example.

One elastic body 5 (left elastic body 5) is provided between the slider 4 and the holding member 6, specifically, between the left slider 4 and the left holding member 6, and the right slider 4 and the right The other elastic body 5 (right elastic body 5) is provided between the pressing members 6. An end (position) of each elastic body 5 on the side opposite to the slider 4 is fixed by each pressing member 6 .
In this example, the pressing member 6 is fixed to the upper half cylinder 11 by a fixture 15. However, the holding member 6 may be fixed to the lower half cylinder 12.

(Example of use)
Painting worker m applies paint only to the bristles 22 of both brushes 2 by holding one handle 10 with his left hand h and holding the other handle 10 with his right hand h and keeping the stick 1 horizontal. The rod-shaped body 1 is brought into contact with the target surface and moved along the surface to be coated in a direction intersecting the longitudinal direction of the rod-shaped body 1 (FIGS. 3(A) and 4).
By impregnating the bristles 22 with liquid paint in advance, two lines d resembling wood grain lines can be simultaneously drawn on the surface to be coated by the above movement (FIG. 5(A)). The white arrow in the figure indicates the direction of the movement (orientation of the rod-shaped body 1 during movement).

During the above movement, by operating the operation unit 3 with the thumb f (FIG. 3(A)), it is possible to gradually change the interval w1 between the two lines d drawn at the same time (FIGS. 5(B), (C)) intervals w2, w3).
In the woodgrain painting equipment shown in FIGS. 1 to 3(A), by pulling the operating part 3 with the pad of the thumb f toward the hand h side where the thumb f is located, the brush 2 is held in the grip held by the hand h. It can be slid toward the hand 10 (along the longitudinal direction of the rod-shaped body 1), and the distance between the two brushes 2 can be gradually widened by the sliding. After widening the distance, the distance can be narrowed by relaxing the fingers and gradually returning the operating section 3 to its original position.

The interval w1 to w5 between two lines d drawn at the same time is also the interval between both brushes 2 (bristle tips 22), so below, the intervals w1 to w5 are adjusted as necessary between both brushes 2 (bristle tips 22). This will be explained as the interval between.
With the gradual change in the interval (from w1 to w2 or w3) between (the bristles 22 of) both brushes 2, the bristles 22 of the brush 2 can be drawn with a curved line d. For example, by operating one operating section 3 to slide one brush 2 (bristle tip 22) and performing the above movement without operating the other operating section 3, both brushes 2 (bristle tip 22) are moved. One of the two lines d drawn at the same time can be drawn as a curve and the other as a straight line without changing the direction of the line (FIG. 5(B)). Furthermore, by operating both operating units 3, each of the two lines d drawn at the same time can be drawn into a curve that approximates a hyperbola to a catenary curve (FIG. 5(C)).

In the example of FIG. 5(B), during the above movement, one of the brushes 2 is slid along the longitudinal direction of the rod-shaped body 1 (in the direction of the black arrow in FIG. 5(B)) by operating one of the operating parts 3. Then, the distance w2 between both brushes 2 is gradually widened from the initial distance w1, and the line d drawn by the one brush 2 is curved.
Further, in the example of FIG. 5(C), during the above movement, both the brushes 2 are moved away from each other along the longitudinal direction of the rod-shaped body 1 (in the direction of the black arrow in FIG. 5(C)) by operating both the operating units 3. By sliding the brushes 2 as shown, the distance w3 between the brushes 2 is gradually widened from the initial distance w1, and the lines d drawn by the brushes 2 are curved.

In both cases of FIGS. 5(B) and 5(C), after drawing a line, the operation unit 3 is gradually moved back toward the original position (the normal position when not pressed) and the brushes 2 are slid closer to each other. , both lines d drawn by both brushes 2 can be curved so that the distance w3 between both brushes 2 is gradually narrowed from the initial distance w1. By moving the brushes 2 closer to each other and away from each other, it is possible to easily draw a woodgrain pattern such as a woodgrain pattern or a woodgrain pattern.
Furthermore, by gradually pressing one operating section 3 and gradually releasing the pressure on the other operating section 3, the interval between both brushes 2 is kept almost constant, without changing the interval between the lines d. You can draw two curves.

As shown in FIG. 6A, a pair of lines can be drawn in the order of d1, d2, d3, d4, d5, and d6. That is, after drawing the two lines d1 in the first movement, the rod-shaped body 1 is returned to the vicinity of the start position of the movement, and at a position shifted from the start position in the direction intersecting the movement direction. , the rod-shaped body 1 starts moving again, and two more lines d2 are added so as to line up with the two lines d1 drawn earlier (FIG. 4). By repeating this addition and adding lines d3 to d6 in order, a woodgrain pattern is painted on the wallpaper k (FIG. 6(A)). The number, shape, arrangement, and drawing order of the lines shown in FIGS. 4 and 6 are merely examples, and the number of lines may be increased or decreased as appropriate from those shown in FIGS. 4 and 6, and the shape, arrangement, and drawing order may be changed. It can be implemented by changing.

For example, instead of sequentially drawing the next two lines sandwiching one of the previously drawn lines as shown in FIGS. 4 and 6(A), Then, with the direction orthogonal to the longitudinal direction of the strip-shaped (rectangular) wallpaper k as the width direction, from the center of the width direction toward both long sides of the wallpaper k (from the inside to the outside), or conversely, from the center of the width direction to both long sides of the wallpaper k, or vice versa. You can also draw lines in order from the beginning to the center in the width direction (from outside to inside), or if the sliding width (sliding range) between both brushes 2 covers the width of the wallpaper in the width direction. It is possible. Of course, even if the slide width is smaller than the width in the width direction, only the center area in the width direction is drawn sequentially from the inside to the outside or from the outside to the inside as described above, and the remaining outside Regarding the areas, lines may be drawn in the order shown in FIG. 4 or FIG. 6(A).

In addition to drawing the streaky wood grain (line) above, draw the knots da of the wood grain (for example, in the area d0 where there is no line) with a regular brush (without using this wood grain painting tool) and paint the wood grain. It is only necessary to complete the process (FIG. 6(B)).

In this example, at least a portion of the surface to be painted is wallpaper k. The surface of wallpaper k may be considered to be the entire surface to be painted, but for example, if wallpaper k is the surface to be painted, and considering the section of line d that protrudes from wallpaper k, strictly speaking, two lines d can be painted at the same time. This is because there are cases where it cannot be said that it has been drawn to the surface to be painted (wallpaper k) (the broken line in FIG. 6(A) indicates the area where line d protrudes).
Normally, the surface of the curing sheet that is wider than the wallpaper k is the surface to be painted, and the wallpaper k to which the wood grain pattern is to be applied is spread over the curing sheet and a line d is drawn using the wood grain painting tool according to the present invention. .

Note that it is also possible to draw a curved line by changing the direction of movement of the rod-shaped body 1 with respect to the surface to be painted without changing the interval between both brushes 2 (without sliding the brushes 2) (Fig. 5 (D)). E)). However, if a natural curve is drawn only by changing the direction of movement of the rod-shaped body 1, it is difficult to naturally change the interval w1 between two curves drawn at the same time. Even if an attempt is made to narrow the distance between the two lines d by moving one brush 2 closer to the line already drawn by the other brush 2, both lines d will form a smooth curve imitating the wood grain. (not shown). After all, if the two lines d are drawn as the above-mentioned smooth curves by changing the direction of movement, the distances w4 and w5 between the two lines d will not be significantly different from the distance w1 before changing the direction of movement.

As mentioned above, it is extremely difficult to draw a natural curve that imitates wood grain using a method that does not involve operations using the operation section 3. By changing the distance between both brushes 2 by operating the operation section 3, two brushes can be drawn at the same time. It is much easier to make the lines of the book the natural curves mentioned above with a woodgrain tone.
That is, providing the operating section 3 so that the distance between the two brushes 2 can be changed by sliding the brushes 2 is extremely effective in drawing wood grain on the wallpaper.
On the other hand, the fact that two lines can be drawn at the same time does not exclude the possibility of curving only by changing the direction of movement, without relying on the operating section 3 or without providing the operating section 3.
By using the operation part 3 in conjunction with changing the direction of movement of the rod 1, a wider wood grain can be expressed, and the maximum width r of the tip 22 of the brush 2 can be utilized to make painting more efficient. It can be done accurately.

(Example of change)
In the examples shown in FIGS. 1 to 3(A), the elastic body 5 is a push spring that exerts a repulsive force when compressed, but the elastic body 5 may also be a tension spring that exerts a repulsive force when stretched. (Figure 3(B)). In the example shown in FIG. 3(B), since the elastic body 5 is a tension spring, the position of the pressing member 6 with respect to each slider 4 in the longitudinal direction of the rod-shaped body 1 is left and right opposite to that in the example of FIGS. 1 to 3. Therefore, the position of the elastic body 5 interposed between the slider 4 and the pressing member 6 is also laterally reversed from the example shown in FIGS. 1 to 3. However, the operating portion 3 in FIG. 3(B) can be operated by pressing the operating portion 3 toward the end of the rod-shaped body 1 with the pad of the thumb f, as in the examples shown in FIGS. 1 to 3(A). The spacing between the brushes 2 can be increased.

In the woodgrain painting equipment shown in Figures 1 to 3 (A) and (B), considering the range in which the operating part 3 can be moved with the average length of the thumb f, the distance between the two brushes 2 placed near the handle 10 is It may be difficult to bring the brushes 2 close to each other to a state of 0 or close to 0, but it is possible to draw the straight-grained wood grain shown in Figures 6(A) and 6(B) using one woodgrain coating. It can be done smoothly with equipment.
On the other hand, when drawing a pair of lines from the inside to the outside as described above, for example, when drawing a woodgrain or heather grain as shown in Figure 6(C), the surface of the wallpaper K is successively partially masked (the paint does not stick to it). It is also possible to draw wood grain using the same procedure as shown in FIGS. 6(A) and 6(B) (not shown).

However, in the case of drawing a board-grain or heather-grain wood grain as shown in FIG. You can draw each of the pair of lines d1 and d2 in the same figure by following the procedure shown in (C) (in the order of d1, d2, d3, d4, d5, d6), making it easy to draw the wood grain intuitively. .
Modified examples suitable for drawing the wood grain illustrated in FIG. 6(C) above are shown in FIGS. 3(C) and 3(D).

In the example shown in FIGS. 3(C) and 3(D), the pressing member 6, the elastic body 5, and the operating section 3 in FIG. When not being operated, both brushes 2 are brought close to each other with almost no gap between them, and a finger hook part 31 is provided on the operating part 3.
The finger rest part 31 is a member formed in an annular shape and allows the thumb to pass through it. The finger hook portion 31 is supported to the operating portion 3 by a support rod 32. Each of the support rods 32 extends along the longitudinal direction of the rod-like body 1 from each of the operating portions 3 toward the left and right handles 10, and the finger hook portion 31 is provided at the tip. The finger hook 31 and the support rod 32 constitute a part of the operating section 3. The finger hook part 31 is provided to the operation part 3 (operation part main body) via the support rod 31, so that the thumb of the hand h gripping the handle 10 can be placed close to each other while the brushes 2 are placed close to each other. It is placed in a position where it can be pulled toward the handle at f.

Hereinafter, as needed, the support rod 32 and the finger hook 31 provided on the left operating section 3a will be referred to as the left support rod 32 and the left finger hook 31, respectively, and the support rod 32 and the finger hook 31 provided on the right operating section 3b will be referred to as the left support rod 32 and the left finger hook 31, respectively. The finger hook portion 31 is referred to as a right support rod 32 and a right finger hook portion 31, respectively.
By resisting the bias of the left and right elastic bodies 5 and pulling the left finger hook 31 to the left, or the right finger hook 31 to the right, or pulling both the left and right finger hooks 31 to the left and right at the same time, the distance between the brushes 2 is removed. The spacing between can be increased. After increasing the distance between the brushes 2, the distance between the brushes 2 can be narrowed by gradually relaxing the pulling force and returning the finger hook 31 to its original position. In the above operation shown in FIGS. 3(C) and 3(D), the front and rear ends intersect at the center of the width direction of the wallpaper k (the front and rear ends You can easily draw a pair of lines (connected).

However, also in the woodgrain painting equipment shown in FIGS. 3(C) and 3(D), the movable width of the left finger hook 31 pulled with the thumb f of the left hand h and the movable width of the right finger hook 31 pulled with the thumb of the right hand h. The slide width of the brush 2 itself is not changed significantly. Therefore, in order to easily draw the lines d3~ located outside the lines d1 and d2 using a single woodgrain painting tool, at least the lines d3~ are drawn on the lower surface of each of the operating parts 3 as shown in FIGS. 10(B) and 10(C). Two attachment parts 33 and 34 are provided. The rear end portion (upper end portion) of the body portion 20 of the brush 21 can be fixed to the attachment portions 33 and 34, respectively. In this example, the attachment parts 33 and 34 are recesses recessed upward, and the body 20 of the brush 2 is forcibly fitted into the recesses, so that the brush 2 can be fixed to the operation part 3 so as to be freely insertable and removable.

Specifically, the lower surface of the left operating section 3a is provided with two mounting sections, an inner mounting section 33 and an outer mounting section 34, spaced from side to side, and the lower surface of the right operating section 3a is also provided with an inner mounting section spaced from side to side. Two mounting parts, 33 and an external mounting part 34, are provided. Each of the inner attachment parts 33 is located closer to the center of the rod-shaped body 1 in the left-right direction (the longitudinal direction of the rod-shaped body 1), and each of the outer attachment parts 34 is located outside of the inner attachment part 33 in the left-right direction, that is, closer to the handle 10. To position. By fixing the brushes 2 to each of the inner attachment parts 33, the brushes 2 are brought close to each other in the same way as the woodgrain painting equipment shown in FIGS. 3C and 3D, and the examples shown in FIGS. Furthermore, when drawing lines after line d3 in the order shown in FIG. Lines can be drawn easily by moving the body 1.

In the examples shown in FIGS. 3(C)(D) and 10(B)(C), the above-mentioned operation of moving the brushes 2 closer to each other and away from each other allows the wood grain (see FIG. 6(C) )) can be easily drawn, and by moving the rod-shaped body 1 while keeping the interval between both brushes 2 almost constant, straight-grain wood grains (Figs. 4 and 6 (A) and (B)) can be easily drawn. I can draw.
In addition, in the woodgrain painting equipment shown in FIGS. 10(B) and 10(C), by attaching the brushes 2 to each of the outer attachment part 34 and the inner attachment part 33, a maximum of four brushes 2 can be applied to the grain. It can be attached to painting equipment and four lines d can be drawn at the same time. By attaching two brushes 2 to each of the outer attachment parts 34 and the inner attachment parts 33, and attaching one brush 2 to each of the other attachment parts, three brushes can be applied at the same time. You can also draw a line d. In the woodgrain painting equipment shown in FIGS. 10(B) and 10(C), there is a By providing an attachment part for the brush 2, it is possible to draw a larger number (5 or more) of lines d at the same time.

As shown in FIGS. 7(A) and 7(B), the elastic body 5 is used as a tension spring that biases the rod-shaped body 1 toward the end, and the operating unit 3 is pressed against the bias by the back of the thumb f (claw side). It is also possible to slide the brushes 2 so as to press and narrow the distance between the brushes 2. In addition, in the case where the brushes 2 are brought closer to each other by pressing with the dorsal side of the thumb f, the elastic body 5 is used as the above-mentioned tension spring, and the elastic body 5 is directed toward the end of the rod-shaped body 1 as shown in FIG. 7(C). It may also be configured as a biasing spring.

The present invention is not limited to the above example in which the brush 20 is provided directly to the operating section 3, and the brush 20 may be connected to the slider 4 without going through the operating section 3. For example, the operation unit 3 may be provided on the upper surface side (of the upper cylinder) of the rod-shaped body 1 separately from the brush 2 (FIGS. 8(A) to 8(D) and FIG. 9). In the woodgrain painting apparatus shown in FIGS. 8 and 9, a slit 16 (upper slit 16) similar to the slit 14 is provided on the upper surface of the upper cylinder 11, and the operating portion 3 is disposed above the slit. Pass the connecting member 7 from above downward through the operating section 3, upper slit 16, slider 4, and slit 14 in order, and screw the tip of the connecting member 7 into the upper end of the body section 20 of the brush 2 to close the operating section. 3, a slider 4, and a brush 2 are integrated.

In this example, a stabilizing member 8 (stabilizer) for assisting stable sliding of the slider 4 is provided at the position of the operating section 3 shown in FIG. 7(C) in place of the operating section 3. The stabilizing member 8 can be a plastic member (plate-shaped body) like the operating section 3. Since the stabilizing member 8 does not need to be pressed with a finger, there is no need for the top and bottom thicknesses that can be pressed with a finger like the operation part 3. In this example, the thickness of the top and bottom of the stabilizing member 8 is the thickness of the operation part 63. It is smaller and more compact than the previous model.
However, the stabilizing member 8 may also have the same vertical thickness as the operating section 3, and may serve as a sub-operating section on which the brush 2 can be slid in response to a thumb operation. Further, as long as the slider 4 can be slid stably, the stabilizing member 8 may be omitted.

Particularly in the example shown in FIGS. 8 and 9, both the holding members 6 are brought to the center in the longitudinal direction of the rod-shaped body 1, and the left and right slits 14 and the upper slit 16 are inserted from both handles 10 side in the longitudinal direction of the rod-shaped body 1. It extends to the center of the rod-shaped body 1, so that a large sliding width of the brush 2 can be ensured. In detail, as shown in FIGS. 8(A) and 8(B), the brushes 2 can be brought closer to each other by grasping the handle 10 and pressing the operating part 3 with the thumb f, which is the same as the example shown in FIG. 7. The hand h holding the handle 10 can be moved from the handle 10 toward the center of the rod-shaped body 1 and pressed further, and the brushes 2 can be brought closer together.
Although not shown, in place of the elastic body 5 that is a push spring shown in FIGS. 8 and 9, an elastic body 5 that is a tension spring is arranged closer to the handle 10 than the slider 4 in the longitudinal direction of the rod-shaped body 1. By doing so, both brushes 2 can be brought closer together. In the example in which the elastic body 5, which is a pull spring, is arranged closer to the handle 10 than the slider 4 as described above, if the left and right slits 14 and the left and right upper slits 16 are also connected, the brushes 2 It is more effective to bring the objects closer together.

In addition, in the example shown in FIGS. 8 and 9, only one elastic body 5, which is a spring, is provided, and the left and right sliders 4 are pressed with both ends of the single elastic body 5, without providing a pressing member 6. (not shown).
In the example shown in FIGS. 8 and 9, by connecting the operating section 3 and the slider 4 via the connecting body 8, the operating section 3 can be arranged closer to the handle than the slider 4. It can be implemented (FIG. 10(A)). In this example, the connecting body 8 is a rod-shaped member bent into an L-shape.
In the examples shown in FIGS. 3(C), 3(D) and 10(B) and 10(C), the left and right support rods 32 are installed separately, without providing the main body of the operation part 3, similarly to the rod-shaped body 1 of FIG. 10(D). It may be directly fixed to the body 20 of the brush 2.

Further, in the example shown in FIG. 10(D), the indicator rod 32 and the finger hook 31, which serve as the operating section 3, are provided on one brush, and the slider 4 integrated with the brush 2 is moved upward from the upper slit 16. A protruding peg 41 is provided as a wire hanging part, and a through hole 17 is provided between the other slider 4 and the handle 10 on the slider 4 side at the upper part (upper half cylinder) of the rod-shaped body 1. , rollers (guide rollers 42, 43) are rotatably provided on the outer circumferential surface and inner circumferential surface of the rod-shaped body 1 (upper half cylinder), respectively, in the vicinity of the through hole 17, and furthermore, one end of the other slider 4 is provided. A second peg 44 is provided as a second wire hanging part, one end of the wire 45 is fixed to the peg 41, the wire 45 is hung on the guide roller 43 through the guide roller 42 and the through hole 17, and the other end of the wire 45 is fixed to the peg 41. By fixing to the second peg 44, both brushes 3 can be slid by operating the finger hook 31 provided only on one of the brushes 2. In the examples shown in FIGS. 10(B) and 10(C), by adopting the same structure as in FIG. 10(D), only one operating section 3 is provided with a finger hook 31, and both operating sections 3 are operated. You can also use it as

Note that only one brush 2 may be slidable in the longitudinal direction of the rod-shaped body 1, and the other brush 2 may be fixed to the rod-shaped body 1 and not slidable (not shown). In this case, the sliding of one brush 2 Although the distance between both brushes 2 is changed, it is also possible to draw a natural curve by interweaving the methods shown in FIGS. 5(D) and 5(E).
In addition to the above, the bristles 21 of the brush 2 may be bundled in an almost perfect circle, or if they are bundled flat, the width direction of the maximum width of the bristles 22 is the longitudinal direction of the rod-shaped body 1. It is not necessary to provide it parallel to the However, with commercially available products that generally allow the bristles 21 of the brush 2 to be bundled flat, the thickest line d can be drawn by making use of the maximum width of the bristles 22, and the thickest line d can be drawn in the longitudinal direction of the rod-shaped body 1. By making the width directions parallel to each other, the paint can be widely applied to the surface to be painted at once.

The elastic body 5 may be made of elastic rubber string or the like. In addition, as a biasing part that presses the slider 4, instead of the elastic body 5 such as a spring or rubber, a well-known means that uses fluid pressure such as hydraulic pressure or air pressure used in a damper etc. is adopted. Good too.
In each of the illustrated examples, the slider 4 and an elastic body 5 (biasing means) for pressing the slider 4 are provided inside the rod-shaped body 1 which is a hollow body (pipe). An annular body (ring or short tube) in which a spiral elastic body 5 (coil spring) is arranged around the outer periphery of the body 1, that is, a rod-shaped body 1 is passed through the center of the spiral spring, and a slider 4 is passed through the rod-shaped body 1. The slider 4 may be provided with an operating section 3 and a brush 2 (not shown).

(Summary)
The woodgrain painting tool of the present invention moves two lines at the same time to the object by moving the rod 1 forward or backward in a front-back direction intersecting the left-right direction with the longitudinal direction of the rod 1 being the left-right direction. It can be drawn on a surface, and by sliding the brush 2 and changing the distance between the two brushes 2 during the movement, the line can be easily drawn as a curved line imitating wood grain.
