  With the above configuration, by operating the chain cord 4, the take-up shaft 7 is rotated to take up and rewind the screen 5, that is, the screen 5 and the weight bar 6 are vertically moved to the inside of the frame 11. We can operate shading and opening. In FIG. 3, the weight bar 6 'in the state of being pulled up to the top is shown by a dotted line.

<Structure of Guide Rail>
The guide rail 20 is a rail that can guide the end of the weight bar 6 of the roll screen 1. In the present embodiment, the guide rail 20 is configured by two vertical guide portions 21 capable of guiding the left and right direction end portions of the weight bar 6. One of the vertical guide portions 21 is installed at the left edge 11b constituting the left side of the frame 11, and can guide the left end portion of the weight bar 6, and the other vertical guide portion 21 is formed on the right side of the frame 11. It is installed at the right edge 11 c to be configured, and can guide the right end of the weight bar 6.

  Note that the vertical guide portion 21 may be installed on only one of the left edge 11 b and the right edge 11 c (in this case, the vertical guide installed at any one of the left edge 11 b and the right edge 11 c A guide rail is configured by the section 21).

  In the following, the vertical guide 21 installed at the right edge 11 c of the frame 11 is taken as an example, and the detailed configuration will be described. In addition, the vertical guide part 21 installed in the left edge part 11b has a left-right symmetrical structure. FIG. 4 is an exploded perspective view of the vertical guide portion 21. As shown in FIG. As shown in FIG. 4, the vertical guide portion 21 mainly includes a non-moving portion 22, a moving portion 23, and a pivot shaft 26, and roughly, a predetermined length from the upper end is a non-moving portion The lower part 22 of the non-moving part 22 (a part other than the non-moving part) is constituted by the moving part 23. That is, the non-moving portion 22 is disposed at a predetermined length from the upper end of the corresponding edge (the right edge 11 c in the vertical guide 21 shown in the example shown), and the moving portion 23 is not It is disposed below the moving unit 22. In the present embodiment, the predetermined length, that is, the length of the non-moving portion 22 is the height direction dimension of the head portion 2 and the weight bar 6 in a state where the screen 5 is pulled up to the upper limit position and wound. It is slightly longer than H in 3).

  FIG. 5 is a plan view (or a cross-sectional view perpendicular to the vertical direction) when the non-moving portion 22 is viewed from above. In FIG. 4, the non-moving portion 22 includes a guide base 31 (first guide base) and a guide plate 32 (first guide plate), each of which is made of a light shielding material (a metal such as aluminum in this example) provided with a light shielding property. Together. The guide base 31 is a substantially rectangular member attached over the entire length in the vertical direction of the non-moving portion 22 on the inner surface of the corresponding edge (the left edge 11 b in this example). The guide plate 32 is a substantially rectangular thin plate member having the same length as the guide base 31 and shielding a gap S1 between the left and right edges of the head portion 2 and the left edge 11b or the right edge 11c opposed thereto. . In the example of the present embodiment illustrated, the guide plate 32 is fixed (integrally) in a substantially L-shaped arrangement substantially perpendicular to the edge of the guide base 31 on the rear side (the outdoor side of the head portion 2). ) (See FIG. 2 above). Although not particularly illustrated, the guide plate 32 may be disposed along the edge of the front side (the indoor side of the head portion 2) of the guide base 31 as well.

  6 and 7 are plan views (or orthogonal cross-sectional views to the vertical direction) when the guide base 33 and the guide plate 34 constituting the moving unit 23 are viewed from above, respectively. In FIGS. 6 and 7, the moving portion 23 is a guide base 33 (second guide base) made of a light shielding material (a metal such as aluminum in this example) and a guide plate 34 (a second guide plate). And the other are rotatably connected to each other (see FIG. 8 described later). The guide base 33 shown in FIG. 6 is a substantially rectangular member attached over the entire length in the vertical direction of the moving portion 23 on the inner surface of the corresponding edge, and the pivot on the rear side penetrates the pivot shaft 26. A hinge piece 33a is provided. The guide plate 34 shown in FIG. 7 has the same length as the guide base 33, and shields the gap S2 between the left and right edges 11b and 11c of the screen 5 (and the weight bar 6). It has a substantially rectangular thin plate-like member, and a hinge piece 34a for allowing the pivot shaft 26 to penetrate is provided at the edge thereof. In the example of the present embodiment illustrated, the guide plate 34 of the moving unit 23 vertically overlaps the hinge pieces 33a and 34a at the edge on the rear side (the outdoor side of the screen 5) with respect to the guide base 33 The guide plate 34 is rotatably coupled around the pivot shaft 26 by passing the pivot shaft 26 formed of a wire-like thin metal wire. Although not shown in particular, the pivot shaft 26 and the guide plate 34 may be disposed together with the edge of the front side (the indoor side of the screen 5) of the guide base 33.

  By connecting the non-moving portion 22 and the moving portion 23 as described above in the vertical direction, the vertical guide portion 21 as shown in FIG. 8 is configured, and only the guide plate 34 in the moving portion 22 can be opened and closed. . That is, in the non-moving portion 22, the guide plate 32 always stands upright with respect to the guide base 31, and always shields the gap S1 between the lateral edge of the head portion 2 and the opposite left edge 11b or right edge 11c. Do. On the other hand, in the moving part 23, the user manually rotates the guide plate 34 to close the guide plate 34 with respect to the guide base 33 (see FIG. 8A). The guide plate 34 can be switched to the open state (FIG. 8 (b)) parallel to the guide base 33.

  In the closed state of the moving part 23 shown in FIG. 8A, the guide plate 34 shields the gap S1 between the left and right edges of the screen 5 and the left edge 11b or the right edge 11c opposed thereto. In the open state of the moving part 23 shown in FIG. 8B, the inside of the frame 11 is widely opened by the width dimension of the horizontal direction by folding the guide plate 34, and much external light is taken in the indoor side it can. In addition, the rotation operation of the guide plate 34 in the moving portion 23 can be performed only in a state where the screen 5 is taken up and pulled up to the upper limit position.

<About weight bar regulation department>
In the present embodiment, the lower end portion of the guide plate 32 of the non-moving portion 22 functions as the weight bar restricting portion 35. As shown in FIG. 3, the weight bar restricting portion 35 is a weight between the outer periphery of the roll 8 of the screen 5 taken up by the take-up shaft 7 on the lower side than the axial center of the take-up shaft 7. Hold the bar 6. For that purpose, the weight bar restricting portion 35 (guide plate 32) has the front side surface (the indoor side surface) of the weight bar restricting portion 35 (the indoor side surface) with the rear side outer peripheral surface The weight bars 6 need to be placed close to each other to such an extent that they can not pass through.

  Here, as shown in FIG. 9, the guide plate 32 of the non-moving portion 22 is disposed in such an arrangement relationship that it is separated to such an extent that the weight bar 6 can pass between it and the rear outer peripheral surface of the roll 8 in the maximum diameter state. A case where the lower end portion of the guide plate 32 does not function as the weight bar restricting portion 35 will be described. FIG. 9A is a partial plan view of the left side end portion of the head portion 2 as viewed from above, and FIG. 9B is a right side view of the right side end portion of the head portion 2. It is the seen partial side view. In FIG. 9B, the light blocking portion 9 and the non-moving portion 22 are not shown, and only the moving portion 23 at the same position as the non-moving portion 22 is illustrated.

  In this FIG. 9, as described above, when the gap between the guide plate 32 of the non-moving portion 22 and the rear outer peripheral surface of the roll 8 in the maximum diameter state is separated, the screen 5 is wound by the winding shaft 7 As shown in the drawing, the weight bar 6 passes the front side of the weight bar regulation portion 35 (lower end portion of the guide plate 32) and is pulled up above the axial center of the winding shaft 7. In this case, a weight bar stopper 36 as illustrated on the upper side of the roll 8 inside the head unit 2 is provided so that the weight bar 6 is not drawn into the rotation (forward rotation) of the roll 8 and falls to the front side. Need to be provided. However, even if the screen 5 is completely wound once and the weight bar 6 is pulled up and then rewound, since the weight bar 6 is easily clogged between the roll 8 and the guide plate 32 this time. It becomes difficult to smoothly deploy the screen 5 in a hanging manner.

  On the other hand, in the present embodiment, the lower end portion of the guide plate 32 functions as the weight bar restricting portion 35 as described above, whereby the smooth drooping performance when the screen 5 is rewound can be secured. That is, as shown in FIG. 10 corresponding to FIG. 9 described above, the weight bar restricting portion 35 is sufficiently close to the rear side outer peripheral surface of the roll 8 in the maximum diameter state. The weight bar 6 can be sandwiched between the outer periphery of the roll 8 below the center and the movement of the weight bar 6 upward (see FIG. 10B). In this pinching state, the lower side of the weight bar 6 is widely opened, so that when the screen 5 is rewound, the screen 5 can be smoothly developed by hanging under the weight of the weight bar 6 without receiving any interference. it can. Further, since the weight bar restricting portion 35 receives the weight bar 6, there is no need to provide the weight bar stopper 36 in the head portion 2, and the configuration in the head portion 2 can be simplified.

  When the lower end portion of the guide plate 32 can function as the weight bar restricting portion 35 as described above, in the gap S2 between the left and right edge 11b or the right edge 11c opposite to the left and right direction edge of the screen 5 The effect of reducing light leakage to improve the light shielding performance can also be obtained at the same time. This point will be described below.

  First, the width dimension in the horizontal direction of each of the guide base 33 and the guide plate 34 in the moving unit 23 is set to be substantially the same because of the overlapping relationship when the moving unit 23 is in the open state. Further, the guide plates 32 and 34 of the non-moving unit 22 and the moving unit 23 are arranged in series in the vertical direction when the moving unit 23 is in the closed state. The width dimension W1 in the horizontal direction is set to be substantially the same, and the respective longitudinal positions are also arranged to coincide with each other. Thus, the width dimension W1 in the horizontal direction (left and right direction) of the guide plates 32 and 34 of the non-moving portion 22 and the moving portion 23 is fixedly set in accordance with the width dimension of the guide base 33, and As shown in FIGS. 9A and 10A, the leading end portions of the guide plates 32 and 34 overlap in the left-right direction with the same overlapping width W2 as the side edge portion of the screen 5.

  Here, when the lower end portion of the guide plate 32 does not function as the weight bar restricting portion 35, that is, when the guide plate 32 of the non-moving portion 22 is largely separated from the rear outer peripheral surface of the roll 8 in the maximum diameter state (see FIG. In the case where the separation distance L1 in 9 (a) is large), the screen 5 is completely unwound, and the moving portion also moves to the rear side outer peripheral surface of the roll 8 in the minimum diameter state, that is, the back surface of the screen 5 at that time. The 23 guide plates 34 will be separated by a relatively large distance. In this case, as shown in FIG. 9A, the incident angle A of the external light entering from the gap between the edge of the guide plate 34 and the edge of the screen 5 becomes large. It will penetrate deeply to the side, that is, the leakage of light will increase.

  On the other hand, as in the present embodiment, when the lower end portion of the guide plate 32 functions as the weight bar restricting portion 35, that is, the guide plate 32 of the non-moving portion 22 has the rear outer peripheral surface of the roll 8 in the maximum diameter state. When they are close to each other (in the case where the separation distance L2 in FIG. 10A is small), the screen 5 is completely unwound and the rear side outer peripheral surface of the roll 8 in the minimum diameter state, that is, the screen 5 at that time. The guide plate 34 of the moving unit 23 is relatively close to the rear surface. In this case, as shown in FIG. 10 (a), the incident angle A of the external light entering from the gap between the edge of the guide plate 34 and the edge of the screen 5 becomes smaller. It is possible to suppress the side approach, that is, to reduce the light leakage and improve the light shielding performance.

<About the shading plate>
Next, the detailed configuration of the head portion 2 and the light shielding plate 9 provided therein will be described. FIG. 11 is a plan view of the roll screen 1 and the guide rail 20 installed in the frame 11 as viewed from above, and shows the roll screen 1 in a side cross section as viewed from the right at the central portion.

  In FIG. 11, the head 2 of the roll screen 1 is a main body 2a installed on the upper edge 11a in the entire left-right direction, and supports 2b extending downward from both left and right ends of the main body 2a. And a light shielding plate 9 extending obliquely rearward and downward from the rear side surface in the entire lateral direction of the main body 2a. The main body portion 2a is constituted by a frame which is formed in a substantially rectangular hollow shape as a whole, and each support portion 2b rotatably supports the central axis of the winding shaft 7 at the lower end portion thereof. The light shielding plate 9 is a thin plate member made of a material having a light shielding property and elasticity as a whole, and is in sliding contact with the rear outer peripheral side surface of the roll 8 of the screen 5 at the central part in the projecting direction It is bent towards.

  With such a configuration, in the state where the screen 5 is wound up most by the winding shaft 7 as shown in the figure (the state where the weight bar 6 is restricted by the weight bar restricting portion 35), The outer peripheral side surface of the roll 8 approaches the lower surface of the main body 2a. Further, although not shown in particular, in the state where the screen 5 is unwound and expanded most (the state where the weight bar 6 is positioned at the lowermost), the outer diameter of the roll 8 becomes substantially the same as the outer diameter of the winding shaft 7 A gap D is generated between the lower surface of the portion 2a. The light shielding plate 9 elastically swings according to the change of the outer diameter of the roll 8 and is always in sliding contact with the rear outer peripheral side surface of the roll 8.

  The light shielding plate 9 that operates in this manner is disposed so as to always overlap and cover the vertical gap between the main body 2 a and the roll 8 in the front-rear direction. Thereby, the light shielding plate 9 can always shield the light leaking from the gap between itself and the main body portion 2a regardless of how the outer diameter of the roll 8 changes, thereby improving the overall light shielding performance. The guide plate 32 is provided at each end of the light shielding plate 9 so as not to interfere with the guide plate 32 of the guide rail 20 even when the roll 8 is in the maximum diameter state and the light shielding plate 9 swings backward most. The notch 9a is formed in accordance with the shape and arrangement of. Further, although not shown in the drawings, in the case where the head portion 2 is not provided with the main body portion 2a, the head portion 2 is installed so as to cover at least between the upper edge portion 11a and the upper side surface of the winding shaft 7 The above light shielding performance can be secured.

<About the installation process of roll screen>
Based on the functions of the weight bar restricting portion 35 and the light shielding plate 9 as described above, steps for installing the entire roll screen 1 in the upper edge portion 11 a will be described below. In addition, in the roll screen 1, it is premised that the screen 5 is previously wound up by the winding shaft 7, and the roll 8 is in the maximum diameter state.

  First, as a first step, the roll screen 1 is disposed at the upper edge portion 11a. At this time, the entire roll screen 1 is disposed slightly on the front side so that the weight bars 6 and the light shielding plates 9 do not interfere with the guide plates 32 of the guide rails 20 (see FIG. 9).

Next, as a second step, the guide on the rear side of the roll screen 1 to such an extent that the weight bar 6 can not pass between the outer periphery of the roll 8 of the screen 5 taken up by the take-up shaft 7 and the weight bar regulating portion 35 Close to the plate 32 (see FIG. 10). At this time, care should be taken not to contact the guide plate 32 with the both ends of the light shielding plate 9 as well.

  Next, as a third step, the head portion 2 (main portion 2a) of the roll screen 1 is fixed to the upper edge portion 11a by fastening with a screw or the like at the position adjusted in the second step.

  By sequentially executing the above first to third steps, the lower end portion of the guide plate 32 can function as the weight bar restricting portion 35, that is, the movement of the weight bar 6 upward from the axial center of the winding shaft 7. Can be restricted, and the light shielding performance in the gap S2 can be improved. In addition, by sequentially executing the first to third steps, the light shielding plate 9 freely swings in response to the change in the outer diameter of the roll 8, and the gap between the main body 2a (upper edge 11a) and the roll 8 is always It is possible to improve the overall light shielding performance by shielding. The combination of the roll screen 1 and the guide rail 20 corresponds to the solar radiation shielding system described in each claim.

<Effect of this embodiment>
As described above, in the present embodiment, the weight bar 6 can be held by the guide plate 32 of the non-moving portion 22 with the outer periphery of the roll 8 of the screen 5 taken up by the take-up shaft 7 The control unit 35 is provided. As a result, the weight bar 6 can be released from the pinched state by its own weight only by rewinding the screen 5 so that the weight bar 6 can hang freely, and the drooping and spreading performance of the roll screen 1 can be improved.

  Further, in the present embodiment, in particular, the guide plate 32 of the non-moving portion 22 has the weight bar restricting portion 35 at the lower end portion thereof. As a result, the guide plate 32 of the non-moving portion 22 is pulled up to the upper limit position to open the lower side of the weight bar 6 in a state of being held by the weight bar restricting portion 35. Therefore, the guide plate 34 of the moving portion 23 is opened. In the state, more ambient light can be made to enter the room.

  Further, in the present embodiment, in particular, the weight bar restricting portion 35 clamps the weight bar 6 below the axial center of the winding shaft 7. As a result, since the lower side of the weight bar 6 is widely opened in the sandwiching state, the screen 5 can be smoothly developed by drooping under the weight of the weight bar 6 without receiving any interference when the screen 5 is rewound. Can.

  Further, in the present embodiment, in particular, the width dimension in the horizontal direction of the guide plate 32 of the non-moving portion 22 and the guide plate 34 of the moving portion 23 is set to be substantially the same. As a result, even when the moving portions 23 are in the closed state, even when the guide plates 32 and 34 are aligned in the vertical direction, the widths of the guide plates 32 and 34 become uniform and the appearance is improved. Even in such a case, when the lower end portion of the guide plate 32 functions as the weight bar restricting portion 35, that is, the guide plate 32 of the non-moving portion 22 approaches the rear outer peripheral surface of the roll 8 in the maximum diameter state. In this case, it is possible to suppress external light entering from the gap between the edge of the guide plate 34 and the edge of the screen 5 to the front side, that is, light leakage can be reduced to improve the light shielding performance.

  Moreover, especially in this embodiment, the said 1st-3rd process is performed in order, and the roll screen 1 is installed in the upper edge part 11a. Thus, the lower end portion of the guide plate 32 can function as the weight bar restricting portion 35, and the movement restriction of the weight bar 6 and the light shielding performance in the gap S2 can be improved. Further, the light shielding performance at the gap between the main body 2a (upper edge 11a) and the roll 8 can be constantly improved.

  Further, in the present embodiment, in particular, a light shielding plate 9 is provided which shields a vertical gap between the main body 2a (upper edge portion 11a) and the winding shaft 7 in a shape which is cut out according to the guide plate 32. Thereby, the light shielding plate 9 can always shield the light leaking from the gap between itself and the main body portion 2a regardless of how the outer diameter of the roll 8 changes, thereby improving the overall light shielding performance.

  In addition to the methods already described above, methods according to the above-described embodiment and each modification may be combined as appropriate for use.

  In addition, although not illustrated one by one, the present invention is to be implemented with various modifications without departing from the scope of the invention.
