Description

Prefabricated blind

The present invention relates to a prefabricated blind, and more particularly, to a prefabricated blind that can be used by easily replacing the blade when the blade is damaged.

Generally, blinds as decorative materials and control of view and light are used for solar control, room and room, cold protection, soundproofing and privacy protection, etc. in windows of offices, laboratories, factories, hotels, restaurants, homes and other buildings.

Currently, curtains, vertical vertical blinds, horizontal horizontal blinds (Horizontal Blind or Venetian Blind), and general width fabrics are wound up or down with a fabric winding rod. Various types of blades with various functions while securing coziness by combining the conventional Roman shade and transparent curtain paper that fold up or down in the form of fabric with the conventional vertical blind, horizontal blind, and Roman shade. is being used

In recent years, shading devices such as verticals and blinds have been widely used in offices, etc. because of the advantage of being able to see a neat interior effect due to the relatively small space occupied unlike curtains.

On the other hand, blinds are widely used to block sunlight transmitted through windows and to protect privacy.

These blinds are configured to selectively block sunlight transmitted through the window by configuring the shading member to reciprocate up and down on the indoor side of the window, or to move horizontally to selectively block sunlight passing through the window. Roll blinds, etc.

In general, solar heat enters the room through the wall or heat flows into the room together with the light of the sun through a window, which is a factor in the increase in the temperature of the room during the daytime. Just by shutting it off, you can block the temperature rise in the room to some extent.

To this end, the blinds are installed on a window frame or a ceiling, etc., and can easily reflect light coming from the outside through the window, and heat flowing through the fabric of the blinds installed on the window frame can be efficiently blocked.

Conventionally, a cloth made of fabric or non-woven fabric that can effectively block sunlight as a blind and create a warm, comfortable and sophisticated indoor atmosphere has been widely used.

However, when cloth is used as a blind, aesthetic functions such as design expressiveness and interior atmosphere production are excellent, but there are disadvantages in terms of durability and maintenance, such as being easily polluted and easily burned.

Recently, decorative blinds have been developed in consideration of indoor and outdoor interiors. In particular, wood-type blinds made of natural wood or synthetic wood are widely used to improve interior properties by grafting the texture and pattern of natural wood to the blinds. have.

However, the conventional wood-type blind requires at least two or more string connection holes on the blade in order to weave and connect the blade to the string for angle adjustment and opening and closing, and these string connection holes are achieved by a separate drilling operation, perforation work is accompanied by the purchase and installation of a perforated machine along with a separate input of manpower.

This inevitably takes a long time to work, and eventually leads to inefficiency of work such as a decrease in productivity as well as cumbersome and inconvenient work. There is a problem that

In addition, when some blades are damaged or damaged due to carelessness, etc., in the conventional wood-type blind, it is impossible to directly replace the damaged blade on the spot. There is a problem in that time and cost are incurred due to the repair.

And, when an order is received, a normal blind visits the site and measures the size, then cuts the wooden board according to the size, and then completes the blade through perforation. There is a problem in that the waste of materials occurs because the leftovers cannot be used and are discarded as they are.

As such, in the conventional blind, it is difficult to give various color changes to the blade.

In other words, in order to change the color, a separate operation is required to color each blade according to the desired design. Since each blade has to be connected by tying each blade individually, there is a problem in that it increases the economic burden on the consumer due to the difficulty of work and the increase in cost due to special order production.

On the other hand, International Publication WO2009/084624 discloses a "blind" having a structure in which both slats 11 are connected using a connecting member 80 .

However, the “blind” has a structure in which the narrow portion 22 is inserted into the concave portion 31 having the upper portion open and the grooves 32 on both sides when the connecting member 80 and the slat 11 are coupled. As a result, it is difficult to sufficiently secure a binding area between each other, and in the end, the coupling force between the concave portion 31 and the narrow portion 22 is weak. In the narrow portion 22 , fitting holes 23 are formed, respectively, and the coupling force is supplemented through the fastening force between these fitting projections 33 and the fitting hole 23 .

In the case of such a "blind", it is very difficult to manufacture the slat 11 including the narrow portion 22 having the fitting hole 23, and the concave portion 31 having the fitting protrusion 33 and the groove 32. Even in the case of the connecting member 8 including

In addition, in the case of the "blind", when the connection member 80 and the slat 11 are separated, the fitting protrusion 33 and the fitting hole 23, which are firmly locked, must be forcibly removed, so the blade replacement operation is difficult. Not only is it very difficult, but there is a high risk that the fitting protrusion 33 or the fitting hole 23 may be damaged.

In addition, in the case of the “blind”, when both slats 11 are connected using the connecting member 80, a step is created between the slat 11 side and the connecting member 80 side, which is disadvantageous in terms of appearance. , There are times when the cord gets caught or tangled in these steps, making it difficult to operate, and it also has the disadvantage of becoming messy as dust accumulates.

Therefore, the present invention has been devised in view of this point, it is possible to connect the blade to the string without forming a string connection hole for connecting the string to the blade, and after installing the blind on the window during use In case some blades are damaged by accident, it is possible to easily replace only the damaged blades on site without removing the blinds. By implementing the blade connector of The purpose is to provide an excellent prefabricated blind in terms of appearance.

In order to achieve the above object, the prefabricated blind provided by the present invention has the following characteristics.

The prefabricated blind includes a plurality of split-type blades, a blade connector for making each individual blade of the split-type blade into a single split-type blade, and a string and a manipulation unit for folding or unfolding the split-type blade. , The split blade is composed of a plurality of individual blades in the form of a hollow extruded bar while having at least one row or more of reinforcing ribs in parallel along the blade longitudinal direction, the blade connector having a connector body having a string hole, It is formed in parallel at both ends of the connector body and is composed of a plurality of connector binders inserted along the blade longitudinal direction in the space between the reinforcing ribs of the individual blades, and the blade connector is arranged side by side between the individual blades on both sides. As the connector binding body of the blade connector is inserted into the space of the individual blades on both sides, each individual blade is connected via the blade connector to form one split blade.

In addition, the width and thickness of the connector body of the blade connector are made to be the same as the width and thickness of the individual blades of the split blade, and the connector binding body is inserted into a structure to fit into the space of the individual blades, It is preferable that the surfaces of the individual blades and the surface of the connector body of the blade connector are made on the same plane.

The prefabricated blind provided by the present invention has the following effects.

First, it is possible to connect the blade to the string without forming a string connecting hole to connect the string to the blade. There is an effect that only damaged blades can be easily replaced and used in the field without any need.

In other words, if some blades are damaged or damaged due to negligence during use after installing the blinds on the windows, it is possible to replace them with new blades directly on site. It is possible to secure the speed and simplicity of the replacement operation, such as removing the need to untie the blinds that are connected to the string one by one from the string and separate them, then weave them together with the replaced blades to the string and connect them again. And the cost burden due to the repair is reduced, there is an effect that the blind can be used economically.

Second, by applying a new blade connector that connects both blades while being inserted into the extruded bar-shaped blade and tightly fitted and bound to the blade reinforcement rib, it is easy to manufacture, inexpensive, and lightweight at the same time Despite its simple structure, it is possible to secure blade strength as well as close coupling between the blade and the blade connector, and it is very easy to connect and disconnect, and it has excellent appearance in terms of appearance, such as showing a smooth appearance without a step or gap with the blade side. It works.

Third, by applying a blade in the form of an extruded bar that can be combined with a new blade connector, it is possible to prevent bending by its own weight as well as securing its own strength compared to the existing full blade, which has disadvantages such as heavy weight and sagging in the middle. There is an effect that can improve the durability and lifespan of the entire blind including the back blade.

Fourth, since it is a structure that connects only the blades while leaving the blind connector and string as it is, the blade can be assembled simply by simply inserting various blades provided for each color into the blade connector. It has the effect of creating a variety of indoor atmospheres, such as being able to change colors in various ways.

Fifth, since the blade connector can be injection molded with plastic, etc., mass production is possible, which is advantageous in terms of cost, and when the blade connector is molded, the string hole into which the string can be inserted can also be molded together, so blind assembly After connecting the blade connector to the frame with a string, inserting and assembling the blinds on both sides of the blade connector directly without drilling the blade can complete the blind assembly. Not only can the efficiency be further increased, but it also has the effect of securing economic feasibility by reducing the labor cost for drilling and the cost of purchasing a drilling machine.

In other words, since the existing product is a type that uses an intermediate thread by making a hole in the blade, it has the disadvantage of requiring an expensive drilling machine to punch the blade, and if there is damage or scratches during the drilling process, the entire blade is removed. On the other hand, in the case of the prefabricated blind of the present invention, it does not require a punching machine, and the product with scratches (individual blades) can be used after removal, and there is an effect of material saving.

Figure 4 is a perspective view showing an installation state of the prefabricated blind according to an embodiment of the present invention;

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

1 and 2 are perspective views showing a prefabricated blind according to an embodiment of the present invention, Figure 3 is a cross-sectional view showing a prefabricated blind according to an embodiment of the present invention.

1 to 3, the prefabricated blind can easily replace the damaged blade with a new one directly in the field even if some blades are damaged during use, and in particular, in the extruded bar type blade with reinforcing ribs. By applying a new blade connector that connects both blades while being inserted, it is possible to secure a close binding force, increase its own durability, and have a structure that can show a smooth appearance without steps or gaps.

To this end, the prefabricated blind is basically a blind frame (reference numeral 20 in FIG. 4 ) having a built-in driving unit (not shown) that provides power when folding or unfolding the blind, and pulling the lowermost blade upward or downward. A string 13 that folds or unfolds each blade by lowering, and a ladder string 21 that supports each blade one by one, when folding or unfolding the blind, or when adjusting the angle of the blade to close or open the blind (14a, 14b).

Therefore, the prefabricated blind can be folded up or unfolded down by the user's manipulation like a general blind, and the amount of sunlight can be adjusted by adjusting the angle of the blade.

Here, the connection structure between the drive unit, the string and the ladder string, and the operation unit, as well as the connection structure between the blade and the string and the ladder string, and the folding and unfolding of the prefabricated blind, and the operation method for angle adjustment are the same as the general blind, so the detailed description is to be omitted.

In addition, the prefabricated blind includes a plurality of split-type blades 10 arranged side by side in the vertical direction of the window.

The split-type blade 10 is formed in a form in which a plurality of individual blades 11 are coupled side by side in a line by a blade connector 12 .

In one embodiment of the present invention, one split blade 10 by connecting the individual blades 11 in the middle with a relatively long length and the individual blades 11 on both sides of the relatively short length with two blade connectors 12 . ) is provided in such a way that

In particular, each individual blade 11 of the split blade 10 is formed in the form of a hollow extruded bar, for example, in the form of a hollow extruded bar having a space 18 therein by extrusion molding.

Here, various materials can be applied to the individual blade 11 constituting the split blade 10, for example, a synthetic wood material made by combining a polymer resin with 50% or more of an eco-friendly material, wood flour, and molding it into a wood pattern; A metal material such as aluminum, a plastic material, etc. may be applied.

At least one row of reinforcing ribs 15, for example, two rows of reinforcing ribs 15, parallel to each other in the longitudinal direction of the blade while maintaining a certain distance in the blade width direction in the interior of the individual blade 11, that is, the space 18 ) is formed.

At this time, the reinforcing rib 15 connects the ceiling surface and the bottom surface of the space 18 of the individual blade 11 and is continuously connected over the entire length of the space 18, and the individual blades 11 It can be integrally molded during extrusion molding of

Accordingly, the weight of the individual blade 11 can be dramatically reduced as the space portion 18 is applied, and as the reinforcing rib 15 is applied in the space portion 18, the weight of the individual blade 11 is long even when the length is long. It is possible to have a strong strength by itself, such as not sagging in the middle of the length, and eventually the durability and lifespan of the blind including the individual blade 11 can be improved.

In addition, the prefabricated blind includes a blade connector 12 as a means for connecting each individual blade 11 of the split blade 10 .

The blade connector 12 is connected between each individual blade 11 of the split blade 10 and serves to make each individual blade 11 into a single split blade 10 .

To this end, the blade connector 12 is made of an integrated structure of the connector body 17 and the connector binding body 19, and the blade connector 12 is manufactured by injection molding using a plastic material or a synthetic wood material. can become

The connector body 17 is in the form of a rectangular thin band-shaped block, and a slit-shaped string hole 16 is formed through the connector body 17, and the blade is spread in the string hole 16 formed in this way. A string 13 for folding can be passed through.

The connector binding body 19 is a portion inserted into the space 18 of the individual blade 11, and is formed in plurality at both ends of the connector body 17 in parallel, and these connector binding bodies 19 ) can be inserted into the space 18 of the individual blade 11, for example, while entering the space 18 formed between the reinforcing ribs 15 along the blade longitudinal direction. do.

Here, the respective connector binding bodies 19 are formed side by side while maintaining an interval corresponding to the flesh thickness of each reinforcing rib 15 of the individual blade 11, and each connector binding body formed in this way ( 19 ) can be snugly fitted into each space 18 created between the reinforcing ribs 15 of the individual blades 11 .

In one embodiment of the present invention, each of the three connector binding bodies 19 on each side is fitted into the three space portions 18 partitioned in the individual blades 11 on both sides to provide a structure in which they are tightly coupled.

That is, as the thickness and width dimensions of the connector binding body 19 are made to correspond to the vertical spacing and left and right widths of each space part 18, the connector binding body 19 is formed in the space part 18. When fitted in the blade connector 12 side and the individual blade 11 side can be tightly coupled.

Of course, the length of the connector binding body 19 can be set to a suitable length that does not easily fall out in the space 18 .

Accordingly, the blade connector 12 is arranged side by side between the individual blades 11 on both sides, and in this state, the connector binding body 19 of the blade connector 12 is spaced between the individual blades 11 on both sides ( 18), each individual blade 11 is connected via the blade connector 12 to form a single split blade 10.

In particular, the width and thickness of the connector body 17 of the blade connector 12 are made equal to the width and thickness of the individual blades 11 of the split blade 10 .

Accordingly, when the connector binding body 19 of the blade connector 12 is fitted in the space 18 of the individual blade 11 when the blade connector 12 and the individual blade 11 are connected, the blade connector 12 ), both ends of the connector body 17 and the respective ends of the individual blades 11 on both sides are in close contact, as a result, the surface of the individual blades 11 on both sides and the surface of the connector body 17 of the blade connector 12 can be coplanar.

That is, when the blade connector 12 and the individual blade 11 are coupled to each other, a smooth surface without a step can be created, and thus the overall appearance of the blind including the blade can be improved.

Figure 4 is a perspective view showing the installation state of the prefabricated blind according to an embodiment of the present invention.

As shown in FIG. 4 , the prefabricated blind 100 is fixedly installed at the upper end of the window using a blind frame 20 , and a plurality of individual blades 11 via a blade connector 12 . The divided blades 10 are arranged side by side up and down in front of the window.

And, among the strings extending downward from the blind frame 20 side of the prefabricated blind 100, one string 13 in the middle extends downward through the string hole 16 of the blade connector 12, and It is coupled to the bottom surface of the split-type blade 10 positioned at the bottom, and two rows of ladder strings 21 on both sides can support each split-type blade 10 one by one.

Therefore, when the user manipulates the manipulation units 14a and 14b by hand, for example, when the manipulation unit 14a on the left side of the drawing is turned by hand or the manipulation unit 14b on the right side of the drawing is pulled by hand, each division The angle of the mold blade 10 can be adjusted, and each split blade 10 can be folded upward or unfolded downward.

In particular, when any one of the plurality of split-type blades 10 is damaged, after taking out the broken split-type blade 10 from the blade connector 12 , a new split-type blade 10 is re-attached to the blade connector 12 . ), so that only the broken split-type blade 10 can be easily replaced without releasing the entire split-type blade 10 by releasing the string 13 .
