Description

The present invention relates to blinds.

Conventionally, the blind is provided with an elevating cord that elevates and opens and closes a shielding material (screen or slats). The elevating cord is hung from a head box that supports the shielding material and is connected to a rail material provided at the lower end of the shielding material. The shielding material can be opened and closed by elevating and lowering the rail material by the elevating cord. ..

In such a structure, the levelness of the rail material (balance between left and right heights) and the elevating height position can be adjusted by adjusting the length of the elevating cord from the head box to the connecting portion. It is possible. In Patent Document 1 below, the end of the elevating cord is connected to the adjusting component on the bottom rail arranged at the bottom of the shade, and the adjusting component includes the first component to which the elevating cord is connected and the bottom rail. By operating the screw arranged between the first adjustment part and the second adjustment part, the first adjustment part moves relative to the second adjustment part. It is disclosed that the lowering position of the bottom rail can be adjusted by moving the knot of the elevating cord.

U.S. Pat. No. 6,509,004

However, the technique disclosed in Patent Document 1 has the advantage that the length of the elevating cord, that is, the descent height of the bottom rail can be finely adjusted by adjusting the screws constituting the adjust component, but the number of component components is large. There is a design problem that the height of the bottom rail that accommodates these increases due to the fact that the screw and the first adjustment part need to be screwed together, which increases in the height direction due to the structure. was there.

In view of the above circumstances, an object of the present invention is to provide a blind capable of easily adjusting the elevating height or the left-right height balance of the rail material while suppressing the number of parts and the dimensions in the height direction. To do.

In order to achieve the above object, the blind according to one embodiment of the present invention includes a shielding material, a rail material connected to the lower end of the shielding material, a support member that supports the shielding material and is attached to a predetermined surface. It has an elevating cord that hangs down from the support member so as to be able to move up and down, one end of which is connected to the rail material, and the rail material is raised and lowered by the raising and lowering.
The rail material has a detachable elevating cord connecting member at an end portion in the longitudinal direction, and the elevating cord connecting member can lock each one end of the elevating cord connecting member, and the connecting position of the elevating cord to the rail material. Has a plurality of locking portions that can be adjusted stepwise.

According to this configuration, the elevating height position of the rail material can be adjusted by simply adjusting the connecting position of the elevating cord (selecting the locking portion) in the elevating cord connecting member provided at the end of the rail material. Alternatively, the left and right heights of the rail material can be balanced, and since the only member required for the adjustment is the elevating cord connecting member having the locking portion, the number of parts for adjustment can be suppressed. Moreover, since it is not necessary to increase the dimension of the elevating cord connecting member in the height direction, it is possible to prevent the design from being deteriorated. Here, the locking portion may be a hole through which the elevating cord can be inserted and locked, or a locking piece or a locking claw on which the elevating cord can be wound or hooked.

One end of the elevating cord may have an enormous portion that is detachably locked to the locking portion, and the elevating cord connecting member is capable of inserting the elevating cord and not inserting the enormous portion. It may have a possible retaining hole. In this case, the elevating cord is inserted into the retaining hole, and the enormous portion thereof is locked to the locking portion.

According to this configuration, since the elevating cord connecting member has a retaining hole, the elevating cord may be disengaged from the locking portion by any chance, or a force that pulls the elevating cord into the rail member acts on the elevating cord during adjustment. Even if it does, the huge part of the elevating cord is locked by the retaining hole, and the elevating cord can be prevented from coming off from the rail cap.

Each of the locking portions includes an insertion hole having a first diameter through which the enormous portion can be inserted, and a locking hole having a second diameter smaller than the first diameter and capable of locking the enormous portion. , The insertion hole and the locking hole may be connected to each other and have a communication hole having a width smaller than the second diameter. In this case, the locking hole is arranged between the insertion hole and the retaining hole.

According to this configuration, an insertion hole and a locking hole are provided in the locking portion, and the locking hole is formed between the insertion hole and the retaining hole, so that the retaining hole can be opened and closed from the retaining hole side. When a pulling force acts on the elevating cord, the locking hole is urged by the enormous portion of the elevating cord, so that the locking state can be strengthened.

The elevating cord connecting member may be integrally formed with a removable rail cap at the end of the rail material.

According to this configuration, the rail cap can function as the elevating cord connecting member by forming the locking portion on the existing rail cap without providing a new member for connecting the elevating cord.

The shielding material is the first shielding material provided on the support member side among the first shielding material and the second shielding material continuously provided in the elevating direction, and the rail material is the first shielding material. It is an intermediate bar connected to the lower end of the shielding material, and the elevating cord may be a dimming cord for elevating and lowering the intermediate bar.

According to this configuration, by using the rail material as the intermediate bar and the elevating cord as the dimming cord, for example, in a twin-type pleated screen in which two pleated fabrics are arranged one above the other, it is easy to touch the user's eyes and the levelness is a concern. You can adjust the left-right balance of the middle bar, which tends to be. Here, the elevating cord connecting member may also be provided at the end of the bottom rail connected to the lower end of the second shielding material. This makes it possible to adjust the height or left-right balance of both the intermediate bar and the bottom rail.

The plurality of locking portions may be provided on the main surface of the elevating cord connecting member so as to be arranged non-parallel in the longitudinal direction of the rail member.

According to this configuration, by effectively utilizing the area of the main surface of the elevating cord connecting member and providing a plurality of locking portions, it is possible to prevent the elevating cord connecting member from becoming large in size.

The blind according to another embodiment of the present invention can be raised and lowered from the shielding material, the rail material connected to the lower end of the shielding material, the support member that supports the shielding material and is attached to a predetermined surface, and the support member. It hangs down, one end of which is connected to the rail material, and has an elevating cord that elevates and elevates the rail material by the elevating and lowering. The rail material has a detachable elevating cord connecting member at an end portion in the longitudinal direction, and the elevating cord connecting member can lock each one end of the elevating cord connecting member, and the connecting position of the elevating cord to the rail material. Has an adjustable locking part. The one end has an enormous portion that is detachably locked to the locking portion. The elevating cord connecting member has a retaining hole through which the elevating cord can be inserted but not through the huge portion. The elevating cord is inserted into the retaining hole so that the enormous portion can be selectively locked between the retaining hole and the locking portion.

According to this configuration, the elevating height position of the rail material can be adjusted simply by adjusting the connecting position of the elevating cord in the elevating cord connecting member provided at the end of the rail material (selecting a retaining hole or a locking portion). It is possible to adjust or balance the left and right heights of the rail material, and since the only member required for the adjustment is the elevating cord connecting member having the locking portion, the number of parts for adjustment can be increased. Since it can be suppressed and it is not necessary to increase the dimension of the elevating cord connecting member in the height direction, it is possible to prevent the design from being deteriorated. Further, even if the elevating cord connecting member has a retaining hole, the elevating cord may be disengaged from the locking portion, or a force that pulls the elevating cord into the rail member acts on the elevating cord during adjustment. , The huge part of the elevating cord is locked by the retaining hole, and the elevating cord can be prevented from coming off from the rail cap.

As described above, according to the present invention, it is possible to easily adjust the elevating height or the left-right height balance of the rail material while suppressing the number of parts and the dimensions in the height direction.

[Pleated screen configuration]
FIG. 1 is a front view of a pleated screen as a blind according to the present embodiment. In the figure, the inside of the headbox is exposed for convenience of explanation, but it is actually covered with a cover.

As shown in both figures, the pleated screen 100 according to the present embodiment includes a head box 1 as a support member and a first pleated cloth 2 and a second pleated cloth 5 as a shielding material supported by the support member. Have.

An intermediate bar 3 as a rail material is connected to the lower end of the first pleated fabric 2, and a bottom rail 6 is connected to the lower end of the second pleated fabric.

Further, the first pleated fabric 2 is formed by being folded in a bellows shape so as to be opened and closed in the Y direction of the figure, and the head box 1 is formed in each portion partitioned by the creases formed in the X direction of the figure. The dimming cord 4 hanging from the above is inserted. The lower end of the dimming cord 4 is connected to the intermediate bar 3.

The second pleated fabric 5 is also formed in the same manner as the first pleated fabric 2, and an elevating cord 7 is inserted through each portion partitioned by each crease. The lower end of the elevating cord 7 is connected to the bottom rail 6.

The first pleated fabric 2 can be opened and closed by raising and lowering the intermediate bar 3 by raising and lowering the dimming cord 4, and the second pleated fabric 5 has a bottom rail 6 raised and lowered by the raising and lowering cord 7. It can be opened and closed by going up and down.

As shown in the figure, the head box 1 rotatably supports the take-up drum 9. As shown in FIG. 2, the head box 1 has a horizontally long rectangular parallelepiped shape, and is fixed to a predetermined surface such as a ceiling surface or a wall surface of a window frame inside a building via a bracket 8 by a screw or the like to form a pleated screen. 100 is installed.

The take-up drum 9 is arranged inside the head box 1 and is supported so as to be integrally rotatable by penetrating the rotating shaft 10.

Although the take-up drum 9 is not visible in the figure, one is provided in parallel on the front side and one on the back side in the figure, and one of them winds and unwinds one end of the dimming cord 4. The other side is connected so that one end of the elevating cord 7 can be wound and unwound. The rotating shafts 10 are also provided on the front side and the back side, respectively, corresponding to them.

Similar to the take-up drum 9 and the rotating shaft 10, two stoppers 12 are provided corresponding to the dimming cord 4 and the elevating cord 7, and each of them rotates the corresponding rotating shaft 10 in the unwinding direction. It is possible to switch between a permissible state and a regulated state.

Similarly, two brakes 11 are provided corresponding to the dimming cord 4 and the elevating cord 7, and the winding speeds of the dimming cord 4 and the elevating cord 7 (rotational speed of the winding drum 9) are reduced, respectively. By doing so, the impact force of the intermediate bar 3 when the first pleated fabric 2 is lowered and the impact force of the bottom rail 6 when the second pleated fabric 2 is lowered are alleviated.

The operation unit 13 is composed of an endless operation cord 14 (for example, a ball chain), a pulley 15 around which the operation cord 14 is wound, and an operation shaft connected so as to rotate integrally with the pulley 15. The screen is raised and lowered according to the raising and lowering operation of the user's operation code 14.

Of the above operation codes 14, the chain on the back side when viewed from the front is used for raising and lowering the dimming code 4 (first pleated fabric 2 and intermediate bar 3), and the chain on the front side is the raising and lowering code 7 (first). 2 Used for raising and lowering the pleated fabric 5 and the bottom rail 6).

Specifically, in the lowering operation of the pleated fabric, when the user pulls the chain on the back side slightly (1 to 2 cm) downward and loosens his / her hand, the stopper 12 allows the rotation shaft 10 to rotate in the unwinding direction. Then, the rotation of the pulley 15 lowers the first pleated fabric 2, and when the chain on the back side is pulled downward again, the stopper 12 functions and the first pleated fabric 2 stops. When the user pulls the chain on the front side downward (1 to 2 cm) and loosens the hand, the stopper 12 allows the rotation shaft 10 to rotate in the unwinding direction, the second pleated fabric 5 descends, and the back side again. When the chain is pulled downward, the stopper 12 functions and the second pleated fabric 5 stops.

On the other hand, in the pleated dough raising operation, when the user slowly pulls the chain on the back side downward, the first pleated dough 2 rises, and when the user releases the hand, the first pleated dough 2 stops. Further, when the user slowly pulls the chain on the front side downward, the second pleated fabric 5 rises, and when the user releases the hand, the second pleated fabric 5 stops.

Both ends of the intermediate bar 3 in the longitudinal direction are opened so that the first pleated fabric 2 can be inserted at the time of assembly, and a rail cap 30 is detachably provided in the opening. Similarly, rail caps 60 are detachably provided at the openings at both ends of the bottom rail 6 in the longitudinal direction.

In the present embodiment, the rail caps 30 provided at both ends of the intermediate bar 3 function as a connecting member that connects to the lower end of the dimming cord 4, and also functions as an adjusting member that can adjust the connecting position. The details of the rail cap 30 will be described below.

[Rail cap configuration]
FIG. 2 is a partially transparent perspective view showing an end portion (including a rail cap 30) of the intermediate bar 3 of FIG. FIG. 3 is a perspective view showing a state in which the rail cap 30 is removed from the intermediate bar 3 shown in FIG. Further, FIG. 4 is a perspective view of the rail cap 30, and FIG. 5 is a plan view of the rail cap 30.

As shown in these figures, the rail cap 30 has a lid portion 30a parallel to the YZ plane covering the openings at both ends of the intermediate bar 3 in the longitudinal direction, and a lid portion 30a protruding from the inner surface of the lid portion 30a and protruding from the opening of the intermediate bar 3. It is composed of a protruding portion 30b that can be inserted into the inside thereof.

The rail cap 30 is inserted into the opening of the intermediate bar 3, and the engaging claw 31 engages with the claw engaging portion 3a, whereby the rail cap 30 is fixed to the intermediate bar 3.

The protruding portion 30b is a main portion of an engaging claw 31 that can engage with the claw engaging portion 3a formed on the XZ plane at both ends of the intermediate bar 3, and, for example, a plate portion having an H-shaped cross section provided below the engaging claw 31. It has a plurality of locking portions 32 and retaining holes 33 formed on the surface.

Each of the plurality of locking portions 32 can lock the lower end of the dimming cord 4, and the length of the dimming cord 4 from the upper end on the headbox 1 side to the lower end can be adjusted stepwise. is there.

Specifically, as shown in FIGS. 4 and 5, the locking portion 32 has an insertion hole 34, a locking hole 35, and a communication hole 36. As shown in FIGS. 2 and 3, the lower end of the dimming cord 4 has a huge portion 4a formed by, for example, a knot, and as shown in FIGS. 4 and 5, the insertion hole 34 has an insertion hole 34. The huge portion 4a has a first diameter through which the huge portion 4a can be inserted, and the locking hole 35 has a second diameter smaller than the first diameter, and the huge portion 4a can be locked. The communication hole 36 has a width smaller than the second diameter, and connects the insertion hole 34 and the locking hole 35. The width of the communication hole 36 is formed to be smaller than the diameter of the dimming cord 4, but since the dimming cord 4 is deformable, the user can use the dimming cord 4 inserted through the insertion hole 34. Presses the light control hole 36 toward the communication hole 36, so that the dimming cord 4 passes through the communication hole 36 and is locked in the locking hole 35.

As shown in FIG. 5, in the present embodiment, each locking portion 32 has a large-diameter circular insertion hole 34 and a small-diameter circular locking hole 35 engaged with each other from the insertion hole 34 when viewed from the plane direction. It is communicated by a communication hole 36 formed so as to be slightly tapered toward the stop hole 35. However, the shapes of the insertion hole 34, the locking hole 35, and the communication hole 36 are not limited to these, and any shape may be used as long as each of the above functions can be exhibited.

Further, in the present embodiment, the locking portions 32 are arranged at equal intervals non-parallel (for example, in a zigzag shape) in the longitudinal direction of the intermediate bar 3 on the main surface of the plate material constituting the protruding portion 30b. Is, for example, three. However, four or more locking portions 32 may be provided, or only two may be provided. By providing the plurality of locking portions 32 in a non-parallel manner in the longitudinal direction of the intermediate bar 3, the area of the main surface of the plate material can be effectively utilized, and the rail cap 30 (protruding portion 30b) can be prevented from becoming large. be able to.

Further, as shown in FIGS. 2 to 5, the retaining hole 33 is formed to have a diameter through which the dimming cord 4 can be inserted and the huge portion 4a cannot be inserted. At the time of manufacture and shipment, as shown in FIGS. 2 and 3, the dimming code 4 is formed with the huge portion 4a after being inserted into the retaining hole 33, and the huge portion 4a is inserted into the retaining hole 33. It is in a locked state, and it is possible to prevent the dimming cord 4 from being inadvertently detached from the rail cap 30.

At the time of assembly, the dimming cord 4 is hung from the head box 1 and passes through an opening (not shown) provided on the surface of the intermediate bar 3 (a position corresponding to the hanging position of the dimming cord 4). After being distributed from the portion toward the end portion in each FIG. X direction, the portion is inserted into the retaining hole 33.

On the other hand, after the installation of the pleated screen 100, for example, if the left-right balance (horizontal level) of the intermediate bar 3 is biased, the user can insert the huge portion 4a into the retaining hole 33. , The connection position of the dimming cord 4 to the intermediate bar 3 is adjusted by locking it in any of the locking portions 32 (locking holes 35). As a result, among the dimming cords 4, the hanging length from the head box 1 to the intermediate bar 3 (the opening for distribution) is shortened, so that the height of the intermediate bar 3 is adjusted and the levelness is adjusted. Can be arranged.

In the present embodiment, the distance between the adjacent locking portions 32 is, for example, about 5 mm, and therefore, the enormous portion 4a is moved to the locking portion 32 (from the left side to the right side in FIG. 5) farther from the retaining hole 33. Each time the drooping length is increased, the drooping length is gradually shortened by 5 mm, making it easier to grasp the adjustment amount.

Here, each locking hole 35 and each communication hole 36 of each locking portion 32 are arranged between the insertion holes 34 and the retaining holes 33. That is, each locking hole 35 and each communication hole 36 are formed in the end direction on the retaining hole 33 side of both ends of each insertion hole 34 in the X direction. As a result, when a force that attracts the dimming cord 4 from the retaining hole 33 side acts during the opening and closing of the first pleated fabric 2, the locking hole 35 is urged by the huge portion 4a of the dimming cord 4. Therefore, the locked state in the locking hole 35 of the huge portion 4a becomes strong.

Further, apart from each of the locking portions 32, the dimming cord 4 is provided with a retaining hole 33 in which the dimming cord 4 is always inserted, so that the dimming cord 4 should be disengaged from any of the locking portions 32. Even if the dimming cord 4 is pulled into the intermediate bar 3 during the above adjustment, the enormous portion 4a of the dimming cord 4 is locked by the retaining hole 33, and the dimming cord is locked. 4 is prevented from coming off the rail cap 30.

[Method of adjusting the connection position of the dimming cord]
Next, a method of adjusting the connection position of the dimming cord 4 using the rail cap 30 will be described.

6, FIG. 7, FIG. 8, and FIG. 9 are diagrams illustrating a procedure for adjusting the connection position of the dimming code 4. In these figures, as an example, a case where the locking position of the huge portion 4a of the dimming cord 4 is changed from the retaining hole 33 to the locking portion 32 closest to the retaining hole 33 will be described. Further, in these figures, the first pleated fabric 2 is not shown.

When adjusting the left-right balance of the intermediate bar 3, the user first presses the engaging claw 31 of the rail cap 30 downward and engages with the claw engaging portion 3a of the intermediate bar 3 as shown in FIG. By releasing the alignment, the rail cap 30 is removed from the intermediate bar 3, and then the enormous portion 4a of the dimming cord 4 is pulled out from the retaining hole 33.

Subsequently, as shown in FIG. 7, the user inserts the enlarged portion 4a of the pulled out dimming cord 4 into the insertion hole 34 of the locking portion 32 closest to the retaining hole 33.

Subsequently, as shown in FIG. 8, the user presses the dimming cord 4 from the insertion hole 34 toward the communication hole 36, moves the dimming cord 4 to the locking hole 35 through the communication hole 36, and causes the dimming cord 4 to move. The huge portion 4a of the above is locked in the locking hole 35.

Then, the user inserts the rail cap 30 into the opening of the intermediate bar 3 in a state where the huge portion 4a is locked in the locking hole 35, and attaches the rail cap 30 by the engaging claw 31. This completes the adjustment work.

10 to 13 are views for explaining the difference in the locked state of the huge portion 4a of the dimming code 4. In these figures, the first pleated dough 2 is not shown. Each FIG. A is a plan view showing a state in which the rail cap 30 is attached to the intermediate bar 3, and each FIG. B is a cross-sectional view (shortward direction of the intermediate bar 3).

10A and 10B show a state in which the enormous portion 4a of the dimming cord 4 is directly locked by the retaining hole 33, and none of the locking portions 32 is used (state at the time of manufacture and shipment).

11A and 11B show a state in which the enormous portion 4a of the dimming cord 4 is locked in the locking hole 33 of the locking portion 32 closest to the retaining hole 33. In this state, the hanging length from the head box 1 of the dimming cord 4 to the intermediate bar 3 (the opening for distribution) is about 5 mm shorter than that in the case of FIG. 10, and the adjustment of the intermediate bar 3 is performed. The height of the edge of the subject moves upwards accordingly.

12A and 12B show a state in which the enormous portion 4a of the dimming cord 4 is locked in the locking hole 33 of the locking portion 32 which is the second closest to the retaining hole 33. In this state, the hanging length from the head box 1 of the dimming cord 4 to the intermediate bar 3 (the opening for distribution) is about 10 mm shorter than that in the case of FIG. 10, and the adjustment of the intermediate bar 3 is performed. The height of the edge of the subject moves upwards accordingly.

13A and 13B show a state in which the enormous portion 4a of the dimming cord 4 is locked in the locking hole 33 of the locking portion 32 farthest from the retaining hole 33. In this state, the hanging length from the head box 1 of the dimming cord 4 to the intermediate bar 3 (the opening for distribution) is about 15 mm shorter than that in the case of FIG. 10, and the adjustment of the intermediate bar 3 is performed. The height of the edge of the subject moves upwards accordingly.

FIG. 14 is a diagram showing how the balance of the left and right heights of the intermediate bar is adjusted according to the connection position of the dimming cord before and after the adjustment.

FIG. A shows a state in which the heights of the intermediate bars 3 are not uniform on the left and right (a state in which they are not parallel to the horizon H). Specifically, the height of the intermediate bar 3 is lower on the right side of the figure than on the left side.

From this state, as shown in FIG. B, the user removes the rail cap 30 from the intermediate bar 3 and uses the above-described method to set the locking position of the huge portion 4a of the dimming cord 4 from the retaining hole 33. After adjusting by moving to one of the locking portions 32 (or to the locking portion 32 farther from the locking portion 32 closer to the retaining hole 33), the rail cap 30 is moved to the intermediate bar 3 again. Attach to.

Then, as shown in FIG. C, the heights of the intermediate bars 3 are aligned on the left and right (parallel to the horizontal line H). As a result, the appearance of the intermediate bar 3 in the stationary state is improved, and the subsequent ascending / descending operation becomes smooth. In addition, in FIG. A, by grasping in advance the difference in height in which the left and right sides of the intermediate bar 3 are not aligned, the enormous portion 4a of the dimming code 4 according to the difference in height is engaged. If the stop position is selected, the left and right heights of the intermediate bar 3 can be easily aligned.

When the left-right imbalance of the intermediate bar 3 is opposite to that shown in the figure (when the right side is higher), the dimming code 4 is connected at the rail cap 30 on the opposite side to that shown in the figure. By adjusting the position in the same way, it is possible to adjust the left-right balance to the horizontal state.

[Summary]
As described above, according to the present embodiment, the intermediate bar is simply adjusted by adjusting the connection position of the dimming cord 4 on the rail cap 30 provided at the end of the intermediate bar 3 (selecting the locking portion 32). Since the rail cap 30 having the locking portion 32 is the only member required for the adjustment, the number of parts for the adjustment can be suppressed. Moreover, since it is not necessary to increase the dimension of the rail cap 30 in the height direction, it is possible to prevent the design from being deteriorated.

Further, in the twin type pleated screen 100 in which two pleated fabrics are arranged on the upper and lower sides, the left-right balance of the intermediate bar 3 which is easily touched by the user's eyes and the horizontality is easily noticed can be easily adjusted.

[Modification example]
The present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the gist of the present technology.

In the above-described embodiment, a plurality of locking portions 32 are formed on the rail cap 30, but only one locking portion may be formed. In that case, by selecting the locking position of the huge portion 4a of the dimming cord 4 between the retaining hole 33 and the locking portion 32, the hanging length from the head box 1 to the intermediate bar 3 of the dimming cord 4 is selected. Can be adjusted.

In the above-described embodiment, the locking portion 32 is formed by the insertion hole 34, the locking hole 35, and the communication hole 36, but the shapes thereof are not limited to those shown in the above-described embodiment. For example, the insertion hole 34, the communication hole 36, and the locking hole 35 may be formed continuously (for example, in a tapered shape so that the diameter becomes smaller in order). Further, the locking portion 32 does not need to be a hole as long as it has a structure capable of locking the elevating cord, and a locking piece or a locking claw (for example, a protrusion) on which the elevating cord can be wound or hooked. It may be formed so as to protrude from the surface of the plate material of the portion 30b).

In the above-described embodiment, the rail cap 30 functions as a connecting member of the dimming cord 4. However, apart from the rail cap 30 (for example, at the upper part or the lower part thereof), the dimming cord connecting member having each of the locking portions 32 (and the retaining hole 33) can be attached to and detached from the end portion of the intermediate bar 3. It may be provided.

In the above-described embodiment, the rail cap 30 of the intermediate bar 3 functions as a connecting member of the dimming cord 4 and an adjusting member of the connecting position, and has a locking portion 32 and a retaining hole 33, while the rail cap of the bottom rail 6 is provided. The 60 simply functioned as a cap and did not have a locking portion or the like as an adjusting member. However, the rail cap 60 of the bottom rail 6 may also have a plurality of locking portions and retaining holes as in the rail cap 30. As a result, not only the left-right balance of the intermediate bar 3 but also the left-right balance and height (minimum lowering position) of the bottom rail 6 can be adjusted by the rail cap.

In the above-described embodiment, an example in which the present invention is applied to a pleated screen 100 having a screen 2 as a shielding material is shown. However, the present invention is not limited to pleated screens, and is similarly applicable to other blinds such as Venetian blinds, roll screens, roman shades, honeycomb screens, etc., in which the shielding material can be opened and closed by an elevating cord. In this case, the shielding material does not have to be composed of a plurality of shielding materials (first pleated fabric 2 and second pleated fabric 5) as in the pleated screen 100 of the above embodiment, and is provided at the lower end of a single shielding material. A rail cap that functions as an elevating cord connecting member similar to the above is provided at the end of the provided bottom rail.
