  First, the outline of the structure of the roll screen and guide rail which concern on this embodiment is demonstrated, referring FIGS. 1-3. FIG. 1 is an external view of the whole as viewed from the front, FIG. 2 is a plan view as viewed from above, and FIG. 3 is a side view as viewed from the right.

  As shown in FIG. 1 to FIG. 3, a roll screen 1 and a guide rail are disposed inside a rectangular frame 11 (frame body) provided on the indoor side of a sash (not shown) provided with a window glass 10. 20 are installed. In FIG. 1, for convenience of illustration, a part of the left side of the roll screen 1 is notched. 2, the illustration of the upper edge portion 11a constituting the upper side of the frame 11 is omitted, and the illustration of the right edge portion 11c constituting the right side of the frame 11 and the chain cord 4 is omitted in FIG.

<Configuration of roll screen>
The roll screen 1 has a head portion 2 that is attached to an inner surface of an upper edge portion 11 a constituting the upper side of the frame 11 via a bracket 51. A winding shaft 7 (see FIG. 10 to be described later) is rotatably housed inside the head portion 2, and a sprocket 3 is provided at the end of one side (right side in the illustrated example). An annular chain cord 4 engaged with the sprocket 3 is exposed from the head portion 2 and hangs down, and the sprocket 3 and the take-up shaft 7 can be rotated in the front-rear direction by pulling down one of the chain cords 4 arranged in the front-rear direction. it can. Further, the upper end of the screen 5 made of cloth or the like having an appropriate light-shielding property is fixed to the take-up shaft 7, and a rod-shaped weight bar 6 having an appropriate weight is fixed to the lower end of the screen 5 hanging from there. Has been. The screen 5 hangs down from the rear side (outdoor side) of the winding shaft 7. Further, a thin light-shielding plate 9 is provided on the rear rear side of the head portion 2 in the entire left-right direction (the light-shielding plate 9 will be described in detail later).

  With the above configuration, by operating the chain cord 4, the winding shaft 7 is rotated to wind and unwind the screen 5, that is, the screen 5 and the weight bar 6 are moved up and down to be inside the frame 11. Shading and opening can be operated. In FIG. 3, the weight bar 6 ′ that is pulled up upward is indicated by a dotted line.

<Configuration 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 and 21 that can guide the left and right end portions of the weight bar 6. One vertical guide portion 21 is installed on the left edge portion 11 b 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 moves the right side of the frame 11. It is installed in the right edge portion 11c that constitutes, and the right end portion of the weight bar 6 can be guided.

  In addition, you may install the vertical guide part 21 with respect to any one of the left edge part 11b and the right edge part 11c (In this case, the vertical guide installed in either one of the left edge part 11b or the right edge part 11c) Part 21 constitutes a guide rail).

  In the following, a detailed configuration of the vertical guide portion 21 installed on the right edge portion 11c of the frame 11 is described as an example. In addition, the vertical guide part 21 installed in the left edge part 11b has a left-right symmetric structure. FIG. 4 is an exploded perspective view of the vertical guide portion 21. As shown in FIG. 4, the vertical guide portion 21 mainly includes a non-moving portion 22, a moving portion 23, and a rotating shaft 26. In general, a predetermined length from the upper end is a non-moving portion. 22, and a lower part (a part other than the non-moving part) of the non-moving part 22 is constituted by the moving part 23. In other words, the non-moving part 22 is arranged at a predetermined length from the upper end of the corresponding edge (the right edge 11c in the vertical guide part 21 in the illustrated example), and the moving part 23 is the non-moving part of the corresponding edge. It is arranged below the moving part 22. In the present embodiment, the predetermined length, that is, the length of the non-moving portion 22 is the height 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 (see FIG. It is a little longer than H) in 3.

  FIG. 5 is a plan view of the non-moving part 22 as viewed from above (or a cross-sectional view orthogonal to the vertical direction). In FIG. 4, the non-moving part 22 includes a guide base 31 (first guide base) and a guide plate 32 (first guide plate) each made of a light shielding material (in this example, a metal such as aluminum) having light shielding properties. Is integrated. The guide base 31 is a substantially rectangular member that is attached over the entire length of the non-moving portion 22 on the inner surface of the corresponding edge portion (the left edge portion 11b in this example). The guide plate 32 is a substantially rectangular thin plate-like member that has the same length as the guide base 31 and shields the gap S1 between the left and right edge portions 11b or the right edge portion 11c of the head portion 2 in the left-right direction. . In the example of the present embodiment shown in the figure, the guide plate 32 is fixed (integrated) in a substantially L-shaped arrangement substantially perpendicular to the edge of the guide base 31 on the rear side (outside of the head portion 2). ) (See FIG. 2 above). Although not particularly illustrated, the guide plate 32 may also be disposed at the edge of the front side of the guide base 31 (the indoor side of the head unit 2).

  6 and 7 are plan views (or orthogonal cross-sectional views with respect to the vertical direction) of the guide base 33 and the guide plate 34 constituting the moving unit 23 as viewed from above. 6 and 7, the moving part 23 includes a guide base 33 (second guide base) and a guide plate 34 (second guide plate) each made of a light shielding material having a light shielding property (in this example, a metal such as aluminum). ) Are connected to each other so as to be rotatable (see FIG. 8 described later). The guide base 33 shown in FIG. 6 is a substantially rectangular member that is attached to the inner surface of the corresponding edge portion over the entire vertical length of the moving portion 23, and the rotation shaft 26 passes through the rear edge portion thereof. 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 edge portions of the screen 5 (and the weight bar 6) and the left edge portion 11b or the right edge portion 11c opposite thereto. The hinge piece 34a which penetrates the rotating shaft 26 is provided in the edge part. In the example of the present embodiment shown in the figure, the guide plate 34 of the moving unit 23 overlaps the guide base 33 with the hinge pieces 33a and 34a in the vertical direction at the edge on the rear side (outside of the screen 5). In addition, the guide plate 34 is rotatably connected around the rotation shaft 26 by passing through the rotation shaft 26 made of a wire-like fine metal wire. Although not particularly illustrated, the rotation shaft 26 and the guide plate 34 may be disposed along the edge of the front side of the guide base 33 (the interior side of the screen 5).

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

  In the closed state of the moving portion 23 shown in FIG. 8A, the guide plate 34 shields the gap S1 between the left and right edge portions of the screen 5 and the left edge portion 11b or the right edge portion 11c facing it. In the open state of the moving part 23 shown in FIG. 8B, the guide plate 34 is folded, so that the inside of the frame 11 is widely opened by the width dimension in the horizontal direction, and a large amount of outside light is taken into the room. it can. The rotation operation of the guide plate 34 in the moving unit 23 can be performed only when the screen 5 is wound up and pulled up to the upper limit position.

<About the weight bar control section>
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 has a weight between the winding shaft 7 and the outer periphery of the roll 8 of the screen 5 wound around the winding shaft 7 on the lower side from the shaft center. Hold the bar 6. For this purpose, the weight bar restricting portion 35 (guide plate 32) has a front surface (inner surface) that is in contact with the rear outer peripheral surface of the roll 8 having the largest diameter after the screen 5 is wound up. It is necessary to install them in such a close relationship that the weight bar 6 cannot pass between them.

  Here, as shown in FIG. 9, the guide plate 32 of the non-moving part 22 is arranged in an arrangement relationship in which the weight bar 6 is separated from the rear outer peripheral surface of the roll 8 in the maximum diameter state so that the weight bar 6 can pass therethrough. In other words, 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 vicinity of the left side end portion of the head portion 2 as viewed from above, and FIG. 9B shows the periphery of the right side end portion of the head portion 2 from the right side. FIG. In FIG. 9B, illustration of the light shielding unit 9 and the non-moving unit 22 is omitted, and only the moving unit 23 at the same position as the non-moving unit 22 is illustrated.

  In FIG. 9, as described above, when 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 are separated, the winding of the screen 5 by the winding shaft 7 is performed. As shown in the figure, the weight bar 6 passes through the front side of the weight bar restricting portion 35 (the lower end portion of the guide plate 32) and is lifted up from the axial center of the take-up shaft 7. In this case, a weight bar stopper 36 as shown on the upper side of the roll 8 is provided inside the head portion 2 so that the weight bar 6 is not drawn forward due to the rotation (forward rotation) of the roll 8. It is necessary to provide it. However, even if the screen 5 is completely wound up once and the weight bar 6 is pulled up and then rewound, the weight bar 6 is easily held between the roll 8 and the guide plate 32 and is easily closed. It becomes difficult to smoothly spread the screen 5 downwardly.

  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, so that smooth drooping and unfolding performance when the screen 5 is rewound can be ensured. That is, as shown in FIG. 10 corresponding to FIG. 9, the weight bar restricting portion 35 is sufficiently close to the rear outer peripheral surface of the roll 8 in the maximum diameter state. The weight bar 6 can be clamped between the outer periphery of the roll 8 below the center and the upward movement thereof can be restricted (see FIG. 10B). In this sandwiched state, the lower side of the weight bar 6 is widely open, so that when the screen 5 is rewound, the screen 5 can be smoothly suspended and deployed by the weight of the weight bar 6 without any interference. it can. Further, since the weight bar restricting portion 35 receives the weight bar 6, it is not necessary to provide the weight bar stopper 36 in the head portion 2, and the configuration in the head portion 2 can be simplified.

  Further, 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 direction edge portions of the screen 5 and the left edge portion 11b or the right edge portion 11c opposed thereto. The effect of reducing light leakage and improving the light shielding performance can be obtained at the same time. This will be described below.

  First, the width dimension in the horizontal direction 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 opened. Further, since the guide plates 32 and 34 of the non-moving part 22 and the moving part 23 are arranged in series in the vertical direction when the moving part 23 is closed, each guide plate 32 and 34 is considered in view of aesthetics. The horizontal width dimension W1 is set to be substantially the same, and the positions in the front-rear direction are also aligned. Thus, the horizontal dimension (left-right direction) width dimension W1 of each guide plate 32, 34 of the non-moving part 22 and the moving part 23 is fixedly set according to the width dimension of the guide base 33, and As shown in FIGS. 9A and 10A, the tip portions of the guide plates 32 and 34 overlap in the left-right direction with the same overlapping width W2 as the side edges 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. 9 (a), when the separation distance L1 is large), the moving portion is also moved to the rear outer peripheral surface of the roll 8 in the minimum diameter state after the screen 5 is rewound, that is, to the back surface of the screen 5 at that time. 23 guide plates 34 are relatively separated from each other. 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 increases, so that the external light is forward in the gap S2. It will enter deeper to the side, that is, the leakage of light will increase.

  In contrast, when the lower end portion of the guide plate 32 functions as the weight bar restricting portion 35 as in the present embodiment, that is, the guide plate 32 of the non-moving portion 22 When they are close to each other (when the separation distance L2 in FIG. 10A is small), the screen 5 is rewound and the rear 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 part 23 is relatively close to the back surface. In this case, as shown in FIG. 10A, 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 small, so the front of the external light in the gap S2 The entry to the side can be suppressed, that is, the light leakage can be reduced and the light shielding performance can be improved.

<About shading plate>
Next, a detailed configuration of the head unit 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 on the frame 11 as seen from above, and shows the roll screen 1 as a side cross section as seen from the right side at the center.

  In FIG. 11, the head portion 2 of the roll screen 1 includes a main body portion 2a installed on the upper edge portion 11a over the entire left and right direction, and a support portion 2b extending downward from both left and right end portions of the main body portion 2a. And a light shielding plate 9 extending obliquely downward from the rear side surface over the entire left and right direction of the main body 2a. The main body portion 2a is configured by a frame that is formed in a hollow, substantially rectangular parallelepiped shape, and each support portion 2b supports the central axis of the winding shaft 7 at its lower end portion so as to be rotatable. The light shielding plate 9 is a thin plate member made of a material having a light shielding property and elasticity as a whole. The light shielding plate 9 is in sliding contact with the rear outer peripheral side surface of the roll 8 of the screen 5 at the center portion in the projecting direction, and the front end side is rearward from the sliding contact. It is bent toward.

  With such a configuration, when the screen 5 is wound most by the winding shaft 7 as shown in the figure (the state where the weight bar 6 is regulated by the weight bar regulating portion 35), the screen 5 in the maximum diameter state is obtained. The outer peripheral side surface of the roll 8 is close to the lower surface of the main body 2a. Although not particularly illustrated, in the state in which the screen 5 is unwound most and unfolded (the weight bar 6 is located at the lowest position), the outer diameter of the roll 8 is substantially the same as the outer diameter of the winding shaft 7. A gap D is formed between the lower surface of the portion 2a. The light shielding plate 9 is elastically rocked in accordance with such a change in 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 arranged so as to always overlap and cover the vertical gap between the main body 2a and the roll 8 in the front-rear direction. Thereby, the light shielding plate 9 can always block light leaking from the gap between the main body 2a and improve the overall light shielding performance regardless of how the outer diameter of the roll 8 changes. Note that the guide plates 32 are provided at both ends of the light shielding plate 9 so that they do not 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 most backward. A notch 9a is formed in accordance with the shape and arrangement. In addition, although not particularly illustrated, when 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 light shielding performance can be ensured.

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

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

  Next, as a second step, the roll screen 1 is guided to the rear side so that the weight bar 6 cannot pass between the outer periphery of the roll 8 of the screen 5 wound around the winding shaft 7 and the weight bar restricting portion 35. It is made to adjoin to the plate 20 (refer FIG. 10). At this time, care is taken not to contact the guide plate 20 with respect to both ends of the light shielding plate 9.

  Next, as the third step, the head portion 2 (main body 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 weight bar 6 moves upward from the axis center of the winding shaft 7. Can be controlled, and the light shielding performance in the gap S2 can be improved. Further, by sequentially executing the first to third steps, the light shielding plate 9 freely swings corresponding to the outer diameter change of the roll 8, and the gap between the main body 2 a (upper edge portion 11 a) and the roll 8 is always kept. The entire light shielding performance can be improved 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.

<Effects of this embodiment>
As described above, in this embodiment, the weight bar 6 can hold the weight bar 6 between the guide plate 32 of the non-moving portion 22 and the outer periphery of the roll 8 of the screen 5 wound around the winding shaft 7. A restricting portion 35 is provided. As a result, the weight bar 6 can be released from its clamping state by its own weight simply by rewinding the screen 5 and can be freely suspended, and the drooping deployment performance of the roll screen 1 can be improved.

  In the present embodiment, in particular, the guide plate 32 of the non-moving part 22 has a weight bar restricting part 35 at its lower end. As a result, the guide plate 32 of the non-moving part 22 is lifted to the upper limit position and opens below the weight bar 6 sandwiched by the weight bar restricting part 35, so that the guide plate 34 of the moving part 23 is opened. When the state is set, more external light can enter the room.

  In this embodiment, in particular, the weight bar restricting portion 35 holds the weight bar 6 below the axis center of the winding shaft 7. As a result, since the lower side of the weight bar 6 is widely opened in the sandwiched state, when the screen 5 is rewound, the screen 5 can be smoothly suspended and deployed by the weight of the weight bar 6 without any interference. Can do.

  In the present embodiment, the guide plate 32 of the non-moving part 22 and the guide plate 34 of the moving part 23 are set to have substantially the same width in the horizontal direction. As a result, even when the moving parts 23 are placed in the closed state, the guide plates 32 and 34 are aligned in the same width in the vertical direction, so that the aesthetics are 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 is close to the rear outer peripheral surface of the roll 8 in the maximum diameter state. In this case, it is possible to suppress the entry of external light entering from the gap between the edge portion of the guide plate 34 and the edge portion of the screen 5, that is, light leakage can be reduced and light blocking performance can be improved.

  In the present embodiment, in particular, the first to third steps are sequentially performed to install the roll screen 1 on the upper edge portion 11a. Thereby, the lower end part of the guide plate 32 can be functioned as the weight bar restricting part 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 plate 9 can always improve the light shielding performance in the gap between the main body 2 a (upper edge portion 11 a) and the roll 8.

  In this embodiment, in particular, a light shielding plate 9 that shields the gap in the vertical direction between the main body 2a (upper edge portion 11a) and the take-up shaft 7 in a shape notched to match the guide plate 32 is provided. Thereby, the light shielding plate 9 can always block light leaking from the gap between the main body 2a and improve the overall light shielding performance regardless of how the outer diameter of the roll 8 changes.

  In addition to those already described above, the methods according to the above-described embodiments and modifications may be used in appropriate combination.

  In addition, although not illustrated one by one, the present invention is implemented with various modifications within a range not departing from the gist thereof.
