It is characterized in that it can be attached to the small head box 120 and the intermediate bar 160 via. (See FIG. 6) Each configuration of this embodiment will be described in detail below.

(Small screen 110)
The small screen 110 (first screen) is a shielding material that closes or opens an opening. The small screen 110 is attached to a small head box 120 (rail material) with a small size to which the small screen 110 with a small cell 112 is attached. The small screen 110 is formed by vertically connecting (joining) cylindrical cells 112 with a hexagonal cross section so that the small screen 110 can be folded and expanded. A cord insertion hole 110a through which the dimming cord 140 and the lifting cord 150 are inserted is formed in the upper and lower surfaces of each cell 112 at the center of the joint where each cell 112 is joined vertically. The width of the cells of the small screen 110 in the front-rear direction is approximately 25 mm in the folded state. Further, the width of the cells of the large screen 190, which will be described later, in the front-rear direction is about 45 mm in the folded state. Note that these dimensions are just an example.

As shown in FIG. 1, the upper small screen 110-1 has an upper end connected to the small head box 120 (rail material), and a lower end connected to the intermediate bar 160 (rail material). Further, the lower small screen 110-2 has an upper end connected to the intermediate bar 160, and a lower end connected to the bottom rail 170 (rail material). The small screen 110, the small head box 120, the middle bar 160, and the bottom rail 170 are connected by a method described below.

The upper small screen 110-1 is raised and lowered by a dimming cord 140 hanging from the small head box 120. As shown in FIG. 2, the dimming cord 140 has an upper end connected to a first winding drum 123-1, which will be described later, and the other end is inserted into the cord insertion hole 110a of the upper small screen 110-1 and connected to the intermediate bar. It is connected to a cord holder 162 provided at 160 . The first winding drum 123-1 winds or unwinds the dimming cord 140, and the intermediate bar 160 moves up and down, thereby raising and lowering the upper small screen 110-1.

The lower small screen 110-2 is raised and lowered by a lifting cord 150. As shown in FIG. 2, the lifting cord 150 has an upper end connected to the second winding drum 123-2, and the other end connected to the cord insertion hole 110a of the upper small screen 110-1, the cord holder 162 of the intermediate bar 160, It is connected to a cord holder 172 provided on the bottom rail 170 by passing through the cord insertion hole 110a of the lower small screen 110-2. The second winding drum 123-2 winds or unwinds the lifting cord 150, and the bottom rail 170 moves up and down, thereby raising and lowering the lower small screen 110-2.

(Small head box 120)
As shown in FIG. 1, the small head box 120 is fixed to an opening in a window frame or ceiling (not shown) via a bracket 121. As shown in FIG. 2, the lower part of the small head box 120 is provided with an opening for attaching and detaching a first mounting plate 130, which will be described later, from above and below, and the first mounting plate 130 is housed inside. A mounting portion 120a is provided as a space for the mounting.

Inside the small head box 120, as shown in FIG. 2, first and second rotating shafts 122-1 and 122-2 are arranged at the front and rear. The first and second rotating shafts 122-1 and 122-2 extend in the longitudinal direction of the small head box 120 and are rotatably supported. The first and second rotating shafts 122-1 and 122-2 each include a winding drum 123, a stopper 124, and a brake 125, which will be described below.

As shown in FIG. 2, the first and second rotating shafts 122-1 and 122-2 pass through the first and second winding drums 123-1 and 123-2, respectively. rotates as one. One ends of the first and second rotating shafts 122-1 and 122-2 are connected to an operation unit 126 provided at one end of the small head box 120. The rotation of the first and second rotating shafts 122-1 and 122-2 is controlled by an operating chain 127 that hangs down from one end of the small head box 120 via an operating unit 126.

As shown in FIG. 2, the upper end of the dimming cord 140 is connected to the first winding drum 123-1 so that it can be wound up and unwound. Further, the upper end of the lifting cord 150 is connected to the second winding drum 123-2 so that it can be wound up and unwound. Since the first winding drum 123-1 and the second winding drum 123-2 are rotated separately by separate operations, the dimming cord 140 and the lifting cord 150 are wound up and unwound separately. Therefore, the upper small screen 110-1 and the lower small screen 110-2 are raised and lowered separately. Specifically, when the back side (outdoor side) of the operation chain 127 is pulled downward, the first rotating shaft 122-1 rotates and the dimming cord 140 is wound around the first winding drum 123-1. , the upper small screen 110-1 rises. Furthermore, when the front side (indoor side) of the operation chain 127 is pulled downward, the second rotating shaft 122-2 rotates and the lifting cord 150 is wound around the second winding drum 123-2, and the lower small screen 110-2 rises.

Furthermore, as shown in FIG. 1, the small head box 120 is provided with a stopper 124 that restricts the downward movement of the small screen 110, and a brake 125 that reduces the downward speed of the small screen 110. The stopper 124 restricts the rotation of the first and second rotation shafts 122-1 and 122-2, and restricts the lowering of the small screen 110. Specifically, when the pulling operation of the operating chain 127 is stopped, the stopper 124 is activated to restrict the lowering of the small screen 110. Further, when the operation chain 127 is pulled by a predetermined amount, the stopper 124 is released. The brake 125 reduces the rotation speed of the first and second rotation shafts 122-1 and 122-2 when the small screen 110 is lowered.

(First mounting plate 130)
The first mounting plate 130 (mounting member) connects the upper small screen 110-1 to the small head box 120 and the intermediate bar 160 in a detachable manner. As shown in FIG. 2, the first mounting plate 130 has a flat plate shape, and a bent portion 130a having a reduced thickness is formed at an intermediate position in the front-rear direction. The first attachment plate 130 can be bent along the longitudinal direction by the bending portion 130a, and can be folded into a chevron shape. A cord insertion hole 130b through which the dimming cord 140 and the lifting cord 150 are inserted is formed in the bent portion 130a.

As shown in FIG. 2, the first mounting plate 130 has approximately the same width as the cell 112 of the upper small screen 110-1, and is fitted into the cell 112. The upper small screen 110-1 is attached to the mounting portion 120a of the small head box 120 from below while bending the first mounting plate 130 into an inverted chevron shape with the first mounting plate 130 fitted into the topmost cell 112. After insertion, the first mounting plate 130 is attached by pushing the bent portion 130a upward so as to form a chevron. At this time, the first mounting plate 130 is slightly longer in width than the mounting part 120a and is locked to the mounting part 120a in a chevron-shaped state, so even if tension is applied, it will fall off from the mounting part 120a due to the wedge effect. There's nothing to do. Note that the upper small screen 110-1 is attached to the small head box 120 and the intermediate bar 160 using the same first attachment plate 130.

As shown in FIG. 2, the second mounting plate 180 that connects the lower small screen 110-2 to the intermediate bar 160 and the bottom rail 170 has a concave shape with a flange in cross section. An end portion of the lower small screen 110-2 is fixed to the bottom portion 180a of the second mounting plate 180. The collar portion 180b of the second mounting plate 180 is engaged with the lower end of the intermediate bar 160 and the upper end of the bottom rail 170, so that the lower small screen 110-2 is connected to the intermediate bar 160 and the bottom rail 170. . Note that the lower small screen 110-2 may be connected to the intermediate bar 160 and the bottom rail 170 using the first mounting plate 130 instead of the second mounting plate 180.

As described above, the intermediate bar 160 connects the lower end of the upper small screen 110-1 and the upper end of the lower small screen 110-2. As shown in FIG. 2, openings are provided at the upper and lower parts of the intermediate bar 160 for attaching and detaching the first attachment plate 130 and the second attachment plate 180. Mounting portions 160a and 160b for locking the plate 180 are provided.

The upper small screen 110-1 has the first mounting plate 130 fitted into the cell 112 at the lower end, is inserted into the intermediate bar 160 from above, and is locked to the mounting portion 160a. At this time, for the same reason as mentioned above, even if tension is applied, the wedge effect prevents it from falling off from the attachment portion 160a. The lower small screen 110-2 has the cell 112 at the upper end fixed to the second mounting plate 180, is inserted into the intermediate bar 160 from the longitudinal direction, and is locked to the mounting portion 160b to prevent it from falling off.

As described above, the bottom rail 170 is connected to the lower end of the lower small screen 110-2. As shown in FIG. 2, an opening for attaching and detaching the second mounting plate 180 is provided in the upper part of the bottom rail 170, and a mounting portion 170a for locking the second mounting plate 180 is provided. ing. The lower small screen 110-2 is fixed to the cell 112 at the lower end and the bottom part 180a of the second mounting plate 180, is inserted into the bottom rail 170 from the longitudinal direction, and is locked to the mounting part 170a to prevent it from falling off. .

The configuration of the honeycomb screen 100 of this embodiment has been described above. Hereinafter, a procedure for connecting the large screen 190 whose cells 112 are larger in size than the upper small screen 110-1 to the first mounting plate 130 will be described with reference to FIGS. 3 and 4. FIG. 3 is a diagram showing a procedure for fixing the large screen 190 to the first mounting plate 130. FIG. 4 is a perspective view showing a state in which the first mounting plate 130 and the connecting piece 192a are fixed.

First, as shown in FIG. 3(a), the uppermost cell 192 of the large screen 190 is opened along the longitudinal direction, the upper part is removed, and the remaining lower part is used to connect the pair of connecting pieces 192a. Configure. The pair of connecting pieces 192a are wider than the first mounting plate 130.

Next, as shown in FIG. 3(b), the first mounting plate 130 is placed on the pair of connecting pieces 192a. At this time, the bent portion 130a of the first mounting plate 130 is aligned with the center of the joint of the cell 192, and the positions of the cord insertion hole 130b of the first mounting plate 130 and the cord insertion hole 190a of the large screen 190 are aligned in the vertical direction. to approximately match the state. Note that since the bent portion 130a serves as a guide for positioning, the first mounting plate 130 can be easily aligned. Then, the pair of connecting pieces 192a are bent so as to cover both sides of the first mounting plate 130 in the transverse direction and fixed with double-sided tape or the like.

Therefore, as shown in FIG. 4, the first mounting plate 130 is connected to the uppermost cell 192. The position of the cord insertion hole 130b of the first mounting plate 130 and the position of the cord insertion hole 190a of each cell 192 of the large screen 190 are approximately aligned in the vertical direction. In this way, the first mounting plate 130 is connected to the large screen 190. As described above, the first attachment plate 130 is attached to the attachment part 120a of the small head box 120, so the large screen 190 of the cell 192, which is larger than the upper small screen 110-1, can be attached to the small head box 120. .

The structure for attaching the large screen 190 to the first mounting plate 130 has been described above. Hereinafter, the structure for attaching the large screen 190 to the small head box 120 will be described in comparison with a conventional attachment structure. First, a conventional mounting structure will be described with reference to FIG. 5. FIG. 5 is a diagram showing a conventional mounting structure for mounting a screen on a head box.

Conventionally, as shown in Figure 5, a mounting plate of approximately the same size as the front-back width of the screen cell is inserted into the cell, and the mounting plate is attached to the mounting portion corresponding to the front-back width of the mounting plate. By attaching it, the screen was attached to the head box. Since the sizes of the mounting plate and the mounting portion vary depending on the cell size, head boxes of different sizes are used depending on the cell size.

First, a structure for attaching the small screen 410, which is composed of cells 412 of the same size as the cells 112 of the small screen 110, to the small head box 120 will be described with reference to FIG. 5(a). The small screen 410 is attached to the attachment part 120a of the small head box 120 with the first attachment plate 130 fitted into the cell 412, as shown in FIG. 5(a).

Next, referring to FIG. 5(b), we will discuss the structure for attaching the large screen 420, which is composed of cells 422 of the same size as the cells 192 of the large screen 190, to the large head box 440, which is larger than the small head box 120. explain. The large screen 420 is attached to the attachment part 440a of the large head box 440 with a large attachment plate 430 larger than the first attachment plate 130 inserted into the cell 422, as shown in FIG. 5(b). . The mounting portion 440a has a size corresponding to the large mounting plate 430, and is larger than the mounting portion 120a.

The conventional mounting structure has been described above. In this way, in the conventional mounting structure, when the size of the screen changes, mounting plates of different sizes are used in accordance with the cell size. This is a problem in that if the first mounting plate 130 is inserted into the cell 422 of the large screen 420 and attached to the small head box 120, the excess portion (screen) of the large screen 420 will protrude from the mounting portion 120a. This is because On the other hand, in this embodiment, this problem can be solved and a common mounting plate can be used regardless of the size of the screen. Hereinafter, a structure for attaching the large screen 190 to the small head box 120 described above will be described with reference to FIG. 6.

As described above, the first mounting plate 130, which is smaller in width than the cell 192, is connected to the large screen 190. Since the first attachment plate 130 is attached to the attachment part 120a of the head box 120, as shown in FIG. I can do it.

(Effects of the first embodiment)
As explained above, according to this embodiment, the large screen 190 is connected to the first mounting plate 130 by the pair of connecting pieces 192a, so the screens are connected to the common first mounting plate 130 regardless of the size of the screen. can be done. More specifically, when the screen to be attached is the small screen 110, the first attachment plate 130 is connected by fitting into the cell 112, and when the screen to be attached is the large screen 190, the first attachment plate 130 is connected to the cell 192. It is connected to a pair of open connection pieces 192a. As a result, it becomes possible to attach the small screen 110 and the large screen 190 of different sizes to a common small head box 120 and intermediate bar 160, and it becomes possible to use common parts.

Further, since the large screen 190 can be attached to the small head box 120 for the small screen 110, the device can be made smaller and the cost can be reduced. Furthermore, since the head box 120 can be made common, mechanical parts such as the winding drum 123 and the operation unit 126, which are built in or attached to the head box, caps, etc. can be made common.

Further, the position of the cord insertion hole 130b formed in the bent portion 130a of the first mounting plate 130 and the position of the cord insertion hole 190a formed in the cell 192 of the large screen 190 are approximately aligned in the vertical direction. Therefore, the above-mentioned mounting structure can be easily realized while maintaining the ease of attaching and detaching the large screen 190 to the small head box 120 and the intermediate bar 160 by the bending portion 130a.

In addition, a pair of connecting pieces can be formed by simply opening the cells of an existing screen by cutting, etc., so there is no need to change the manufacturing process of the screen itself in order to form the connecting pieces. A mounting structure can be realized.

Further, since the pair of connecting pieces 192a are fixedly attached to the first mounting plate 130 so as to cover both sides in the lateral direction, the large screen 190 can be easily attached to the first mounting plate 130. Furthermore, there is no need to strictly control the length of each of the pair of connecting pieces 192a.

(Second embodiment)
Next, a screen mounting structure according to a second embodiment will be described with reference to FIGS. 7 and 8. FIG. 7 is a sectional view showing the third mounting plate 230 of the honeycomb screen 200 of the second embodiment. FIG. 8 is a sectional view showing a state in which the third mounting plate 230 is attached to the large head box 240 and the small head box 250. This embodiment differs from the first embodiment in the configuration of the third mounting plate 230. This embodiment will be mainly described with respect to the points that are different from the first embodiment. Components having substantially the same functional configuration are designated by the same reference numerals to omit redundant explanation.

The size of the third mounting plate 230 of this embodiment in the front and back direction can be changed by folding or unfolding the third mounting plate 230. Therefore, the same screen 210 can be attached to the large head box 240 and the small head box 250 of different sizes by one third attachment plate 230.

As shown in FIG. 7A, the third mounting plate 230 has easy-folding portions 230b formed at two locations spaced apart in the front-rear direction of the bending portion 230a. The third mounting plate 230 can be folded along the longitudinal direction of the cell by the easy-folding portion 230b, and the size in the front-rear direction can be changed.
