  FIGS. 1 to 9 show a first embodiment of the screen device according to the present invention, which is a horizontal pulling type of the type in which the screen 10 is accommodated by being wound around the winding shaft 6a in the winding box 6. FIG. An example of the configuration of a single-drawing screen device is shown. In particular, in the horizontal-winding screen device, the outer dimensions of the peripheral frame 1 of the screen device are the size of the installation space of the screen device such as a building opening. The screen assembly 14 (see FIG. 9) to be assembled in the peripheral frame 1 of the screen device can be easily attached to and detached from the peripheral frame 1 by using the configuration for that purpose. The configuration shown in FIG.

  The configuration of the screen device will be specifically described. First, as shown in FIG. 1, the peripheral frame 1 of the screen device is disposed at least between a pair of side frames 3 and 4 and their upper ends. And an upper frame 5. The side frame 3, which is one of the side frames, includes a winding box 6 that houses a winding shaft 6 a that winds one end of a screen 10 to be stretched in the peripheral frame by a biasing force of a winding spring 6 b, and the winding box 6. An attachment member 7 attached to a building opening or the like is attached so as to be separable by a hanging bracket 7a and a latch 7b as shown in FIG. Further, the other side frame 4 is configured as a receiving frame on which the movable rod 8 attached to the other end of the screen 10 wound around the winding shaft 6a is held in contact when the screen 10 is expanded by the movable rod 8. Has been.

  On the other hand, as shown in FIGS. 1, 2 and 4, the screen 10 wound around the take-up shaft 6a is attached with a large number of engaging elements 10a and 10b along both side edges. The edge side engaging element 10 a is engaged with the guide rail 11 in the upper frame 5. As shown in FIGS. 1 and 2, the guide rail 11 for slidably engaging a large number of engaging elements 10a in the upper frame 5 is provided with the engaging element 10a in a slit 11b at the lip of the sliding groove 11a. An inner rail made of synthetic resin with good slidability, which can be guided by being slidably engaged, is supported by the rail support frame 12 in the upper frame 5.

  Further, the rail support frame 12 has the movable rod 8 as shown in FIG. 8 in the state shown in FIG. 5 in which the movable rod 8 is in contact with the winding box 6 by winding the screen 10 onto the winding shaft 6a. 8 is foldably connected to the upper portion of the winding box 6 so that it can be bent in a direction along the line 8. Thereby, the winding box 6 constituting a part of the peripheral frame, the movable rod 8 that abuts on the winding box 6, the rail support frame 12 in the upper frame 5 bent in the direction along them, and integrated with them. However, the screen assembly 14 including the members constituting the lower guide rail 13 described below is an independent component that can be detached from the mounting member 7.

  Furthermore, a latch that is detachably fitted into a latch receiver 18 provided on the receiving frame at a distal end portion of the rail support frame 12 that supports the guide rail 11 in the upper frame 5 on the receiving frame (side frame 4) side. 17 is provided to be extendable and contractible. The latch 17 can be fixed by a screw or the like at an arbitrary expansion / contraction position. However, as shown in FIG. 6, it is assumed that the latch 17 is urged in the extension direction by a spring 19 in the rail support frame 12, and the trigger 20 Thus, the latch 17 is pulled back against the urging force of the spring 19 so as to be detachable from the latch receiver 18.

  7A shows a state in which the latch 17 is inserted into the latch receiver 18 with a maximum length that can be extended, and FIG. 7B shows that the latch 17 is inserted into the latch receiver 18 with a minimum length. It shows the state that was made to. The width of the peripheral frame 1 of the screen device, which is smaller than the width of the building opening, is adjusted to be slightly larger than the width of the building opening within the length corresponding to the difference in the amount of protrusion of the latch 17 in both figures. Can be adapted. If the side frame inner surface 4a below the latch receiver 18 is a hard sliding surface, the latch 17 is received by the action of the spring 19 only by returning the rail support frame 12 from the state shown in FIG. 18 can be engaged.

  The peripheral frame 1 of the screen device does not necessarily require the lower frame facing the upper frame 5, but the engaging element 10 b on the lower end side of the screen 10 is placed between the lower ends of the pair of side frames 3, 4. It is desirable to slidably engage with the guide rails to be disposed. However, since it is also desired to make the lower frame high enough to be barrier-free, the lower ends of the side frames 3 and 4 are here. As a guide rail 13 disposed between them, a barrier-free type guide rail (screen guide) which is led out to the installation portion of the lower frame only when the screen 10 is stretched and is stored in the movable rod 8 when the screen 10 is wound up. 13), the engaging element 10b at the lower edge of the screen 10 is slidably guided.

  The configuration of the guide rail 13 will be described in detail. As shown in FIGS. 1 and 4, the screen guide is formed by a flexible wire 16 having a large number of guide pieces 15 inserted into the upper portion thereof. In the center of the upper surface of each guide piece 15 of the guide rail 13, a slit 15a for engaging the engaging element 10b at the lower end of the screen 10 is formed in a series of slits. By arranging the rows so as to form rows, the engaging elements 10b can be slidably engaged along the slit rows.

The screen guide constituting the guide rail 13 has one end thereof connected to the lower end of the screen outlet 6c of the winding box 6 in FIG. The other end is bent to the guide housing cylinder 8a provided in the movable rod 8 shown in FIGS. 3 and 4 from the lower end of the movable rod 8 as the movable rod 8 is moved. So that it can be led into and out.
In order to stably move the screen guide constituted by the connection of the guide piece 15 and the lower end of the movable rod 8 along the original traveling path, the screen guide is guided to the position where the lower frame of the peripheral frame 1 is installed. The travel guide 13a is provided, but the travel guide does not have such a height as to cause the barrier-free obstacle.

  Further, in order to move the movable rod 8 in parallel during the opening / closing operation of the screen 10, as shown in FIG. 1, the wire for parallel movement is connected to the insertion end of the screen guide in which the above-mentioned many guide pieces 15 are connected into the guide accommodating cylinder 8a. 21 is connected, the leading end of the wire 21 is guided from the upper end of the guide receiving cylinder 8a to the leading end side of the latch 17, and is connected to the latch 17 in the extended position by the urging force of the spring 19, so that the inside of the guide receiving cylinder 8a Smooth movement of the screen guide along The configuration in which the movable rod 8 is translated using the parallel movement wire 21 is an adjustment for adjusting the length of the screen guide 13 according to the expansion and contraction of the latch 17 provided on the rail support frame 12 in the upper frame 5. It also functions as a mechanism.

  When a general lower frame is provided without requiring a barrier-free lower frame facing the upper frame 5, the lower frame is provided on the upper frame of the screen device according to the present invention. What is necessary is just to provide the guide rail 11 so that it may become symmetrical with respect to what was provided in the said upper frame 5. FIG. In this case, in order to adjust the outer dimension of the peripheral frame 1 of the screen device in accordance with the size of the installation space such as a building opening in which the screen frame is installed, the engaging element 10b on the lower end side of the screen 10 is provided with the above-described engagement element 10b. A guide rail 13 slidably engaged with a guide rail 13 (inner rail) disposed between the lower ends of the pair of side frames 3 and 4, and the guide rail 13 disposed between the lower ends of the pair of side frames 3 and 4 is Similarly to the latch 17 provided on the rail support frame 12 in the upper frame, it is necessary that the length can be adjusted by the expansion and contraction.

  As described above, the winding box 6 is detachably attached to the attachment member 7 for attaching it to the building opening or the like by the metal fitting 7a and the latch 7b that slides up and down on the attachment member 7. Therefore, the movable rod 8 that comes into contact with the winding box 6, the rail support frame 12 including the guide rail 11 in the upper frame 5 bent in the direction along them, and the guide integrated with them. Since the screen assembly 14 including a member such as the rail 13 can be an independent component in the peripheral frame 1 of the screen device, it can be easily attached to and detached from the peripheral frame 1 of the screen device. As a result, the screen device can be easily assembled and maintained.

  In addition, since a retractable latch 17 is provided at the end of the rail support frame 12 that supports the guide rail 11 in the upper frame 5 on the receiving frame side, the length of the upper frame 5 is increased according to the expansion and contraction of the latch 17. Therefore, the screen is provided with a length adjusting mechanism in which the side frame 3 of the upper frame 5 and the end portion 5a on the side of the upper frame 5 are formed to be extendable and contractable by sliding relative to the main body. It is necessary to be able to adjust the vertical dimension of the peripheral frame 1 according to the height of the installation space. Therefore, after the total length of the upper frame 5 is adjusted to the above length, it is separated from the side frames 3 and 4. The formed upper frame 5 is moved up and down so that its height can be adjusted.

  In addition, when the length of the upper frame 5 itself or the height of the upper frame 5 on the side frames 3 and 4 is adjusted by the adjustment mechanism, screws or the like for fixing the side frames and the upper frame to the adjusted state. However, in the embodiment shown in the drawing, the side frame and the upper frame are fixed to the peripheral frame 1 by fixing those side frames and the upper frame to the opening of the building where the screen device is installed. It is formed so as to retain its form.

10 to 15 show the configuration of a double-drawing screen device which is a second embodiment of the screen device according to the present invention.
This double-drawing screen device basically has a configuration in which the receiving frames in the pair of screen devices of the first embodiment are omitted and the movable rods 38 of these screen devices are summed at the center. The peripheral frame 31 of the double-drawing screen device includes at least a pair of side frames 33 and 34 and an upper frame 35 disposed between the upper ends thereof.

As can be seen from FIG. 11, the pair of side frames 33 and 34 in FIG. 10 is a winding shaft for winding one end of each screen 10 stretched on both sides of the intermediate position of the upper frame 35 with the urging force of the winding spring. A winding box 36 containing 36a is provided, and each winding box 36 is detachably attached to the attachment member 7 attached to the building opening as in the screen device of the first embodiment. It is configured as.
Further, although the upper frame 35 is divided into two at an intermediate position where a latch receiving support member 48 described later is provided, it may be a single one. The intermediate position is a position where the screen device to be installed is divided into two, but is not necessarily a position where the left and right screen lengths are equally divided.

  As in the case of the first embodiment of FIGS. 1 and 4, the screens 10 wound on the two winding shafts 36a have a large number of engaging elements 10a and 10b attached along the upper and lower side edges. The guide rail 41A (see the guide rail 11 in FIGS. 1 and 2) provided in the upper frame 35A on the one side frame 33 side than the middle position of the upper frame 35 is connected to the screen 10 on the one side frame 33 side. The upper end side engagement element 10a is slidably engaged, and the guide rail 41B provided in the upper frame 35B on the other side frame 34 side than the intermediate position is connected to the screen on the other side frame 34 side. The engaging element 10a on the upper end side of 10 is slidably engaged. Further, the engaging element 10b on the lower end side of the both screens 10 is also engaged with guide rails 43A and 43B (screen guides) disposed between the lower end sides of the pair of side frames 33 and 34 so that both screens are engaged. The upper and lower ends of 10 are guided.

  The guide rails 43A and 43B disposed on the lower ends of the pair of side frames 33 and 34 are barrier-free type guide rails (screens) described in the first embodiment with reference to FIGS. Since the structure and operation of the guide 13 are not changed, and the mechanism for moving the movable rod 8 attached to the guide rail 13 is not changed, the guide rail shown in FIGS. 10 and 11 is used here. 43A and 43B are denoted by reference numerals assigned to respective portions of the guide rail 13 in FIGS. 1 and 4 and description thereof is omitted.

  In the upper frames 35A and 35B on both sides of the intermediate position of the upper frame 35, guide rails 41A and 41B similar to those of the first embodiment are supported by the rail support frames 42A and 42B. , 42B are provided with latches 47A, 47B similar to those of the first embodiment, respectively, at the front end portions on the intermediate position side thereof so as to be extendable. As in the first embodiment shown in FIG. 6, the latches 47A and 47B are preferably urged in the extending direction by the spring 19 in the rail support frame, and the trigger shown in FIG. 50, the latches 47A and 47B are formed to be detachable from a later-described latch receiver 49 provided on the latch receiver support member 48 against the biasing force of the spring 19 by the same operation as the trigger 20 shown in FIG. It is desirable to do.

  Further, in the state where the movable rod 38 is in contact with the winding box 36 by the winding of the screen 10 onto the winding shaft 36a (the state of FIG. 5 in the first embodiment), the rail support frame 42 in FIG. Similar to the first embodiment described with reference to the above, the upper portion of the winding box 36 is foldably connected so that it can be bent in the direction along the movable rod 38 and can be suspended. Therefore, the winding box 36 constituting a part of the peripheral frame, the movable rod 38 in contact with the winding box 36, the rail support frame 42A or 42B in the upper frame bent in the direction along them, and integrated with them. However, the two screen assemblies 44 including the members constituting the lower guide rail 43A or 43B are independent components that can be detached from the mounting member 37, and as in the first embodiment, this is used as the screen assembly of the screen device. It can be easily attached to and detached from the peripheral frame 31.

  As can be seen from FIGS. 12 and 14, the latch receiving support member 48 connected between the upper frame 35A and the upper frame 35B is engaged with the latches 47A and 47B at the ends of the rail support frames 42A and 42B. The latch receiver 49 to be freely inserted is configured to have a rectangular hole-shaped receiving portion 49a that receives the insertion of the tips of the latches 47A and 47B from the rail support frames 42A and 42B on both sides.

  That is, the latches 47A and 47B have a form in which the left and right halves are omitted in a plan view as clearly shown in the plan view of FIG. 6, and the screen is as in the second embodiment of the present invention. In the case where the device is a double-drawing device, if the latches 47A and 47B are positioned so that the missing sides of the opposed latches 47A and 47B face each other and fit into the latch receiver 49, the latch receivers of both latches 47A and 47B 49 can be formed in a single square hole shape into which both latches can be fitted, and the configuration can be simplified accordingly. However, the latches 47A and 47B and the latch receiver 49 are not necessarily configured as described above, and a pair of the latch and the latch receiver according to the first embodiment may be provided side by side.

  The rail support frames 42A and 42B having the extendable latches 47A and 47B described above have a maximum length that allows the latch to be extended, as in the first embodiment described above with reference to FIG. The width of the opening of the building within the length range between FIG. 7 (a) in which the latch is inserted into the latch receiver and FIG. 7 (b) in which the latch is inserted into the latch receiver with a minimum length. The width of the peripheral frame 1 of the smaller screen device can be adjusted, and the screen device can be adapted to the building opening.

  Further, because the rail support frames 42A and 42B for supporting the guide rails 41A and 41B in the upper frame 35 are provided with the extendable latches 47A and 47B at the receiving frame side, the expansion and contraction of the latches 47A and 47B is provided. Accordingly, the length of the upper frame 35 needs to be expanded and contracted. Therefore, the side frame 33 side of the upper frame 35 and the end portion 35C of the upper frame on the side of the upper frame 35 are formed so as to be extendable and contractable by sliding relative to the main body. The adjustment mechanism is provided.

  On the other hand, the vertical dimension of the peripheral frame 31 needs to be adjustable according to the height of the installation space of the screen device, but the side frame is adjusted after adjusting the length of the upper frame 5 as described above. When the upper frame 35 separated from 33 and 34 is to be raised and lowered, the pair of rail support frames 42A and 42B are rotatably connected to the upper ends of the side frames 33 and 34 and cannot be raised or lowered. 49 cannot be fixed to the latch receiving support member 48 integrated with the upper frame 35.
