<Configuration of roll screen>
The roll screen 1 (sunlight shielding device) has a head portion 2 (storage portion) that is attached to an inner surface of an upper edge portion 11a that constitutes the upper side of the frame 11 via a bracket 51. A winding shaft 7 (see FIG. 9 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. Moreover, the upper end of the screen 5 (sunlight shielding member) made of cloth or the like having an appropriate light-shielding property is fixed to the take-up shaft 7, and the lower end of the screen 5 suspended therefrom has a rod-like shape having an appropriate weight. The weight bar 6 is fixed. The screen 5 hangs down from the rear side (outdoor side) of the winding shaft 7. In addition, a thin light-shielding plate 9 is provided on the rear rear side of the head portion 2 over the entire left and right direction.

  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 H1) 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. 5, 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 having a light shielding property (in this example, a metal such as aluminum). Is integrated. The guide base 31 is a substantially rectangular member that is attached over the entire length in the vertical direction of the non-moving portion 22 on the inner surface of the corresponding edge portion (the left edge portion 11b in this example), and considering its installation stability. The thickness dimension T in the left-right direction (the installation height dimension from the inner surface of the right edge portion 11c) is set to about 5 mm, for 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, a guide plate 32 may be disposed along the edge of the front side of the guide base 31 (the interior side of the head portion 2) to form a substantially “U” shape as a whole.

  In the present embodiment, the guide base 31 of the non-moving portion 22 has a space portion 31a in which a range corresponding to a predetermined height dimension is cut from the upper end portion (see FIGS. 3 and 8). . The space portion 31a is for preventing interference with the left and right end portions of the head portion 2, and the height direction dimension thereof is the height of the head portion 2 in a state where the screen 5 is pulled up to the upper limit position and wound up. It is set slightly longer than the vertical dimension (H2 in FIG. 3) (see FIG. 3).

  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 over the entire length of the moving part 23 on the inner surface of the corresponding edge part, and is substantially the same as the guide base 31 part of the non-moving part 22. The hinge piece 33a which penetrates the rotating shaft 26 is provided in the edge part in the shape and the back side. 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. This is a substantially rectangular thin plate-like member that has substantially the same shape as that of the guide plate 31 of the non-moving portion 22, and a hinge piece 34 a that penetrates the rotating shaft 26 is provided at the edge thereof. 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 are also arranged at the edge of the front side of the guide base 33 (the interior side of the screen 5) so that the entire shape is substantially “U” -shaped. Also good.

  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.

<Relationship between roll screen and guide rail>
Next, the positional relationship between the roll screen 1 and the guide rail 20 will be described with reference to FIG. FIG. 9 is a plan view of the roll screen 1 and the guide rail 20 installed on the frame 11 as viewed from above, and shows the roll screen 1 as a side cross section as viewed from the right in the center.

  In FIG. 9, 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. (Support member) and a light shielding plate 9 extending from the rear side surface to the rear obliquely lower side 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.

  Here, in general, the roll screen 1 and the vertical guide part 21 are often made by custom-made according to the dimensions of each part of the frame 11, and the width dimensions of the head part 2 and the screen 5, or the non-moving part 22 and the movement. Each length dimension of the section 23 is also set individually for each lot. Of these, the width dimension Lh in the left-right direction of the head portion 2 is set so that a marginal clearance S0 of about 5 mm is provided at both ends thereof in consideration of ease of installation. That is, in the illustrated example, the lateral width dimension Lh of the head portion 2 is about 10 mm shorter than the inner lateral width Lg of the frame 11 (corresponding to the separation distance between the left edge portion 11b and the right edge portion 11c). Is set. In general, the horizontal width dimension Lh (horizontal width dimension) of the head portion 2 is set to be longer than the horizontal width dimension Ls (horizontal width dimension) of the screen 5.

  However, it is difficult to install the guide rail 20 later as compared with the state in which the roll screen 1 is used with the head portion 2 having such a width Lh first installed on the frame 11. That is, as described above, the margin gap S0 between the both end portions of the head portion 2 and the left edge portion 11b and the right edge portion 11c is about 5 mm, but has a thickness dimension T of about 5 mm there. It becomes difficult to arrange the guide base 31 of the non-moving part 22.

  On the other hand, in the guide rail 20 of the present embodiment, as described above, the guide base 31 of the non-moving part 22 is slightly longer than the height direction dimension (H2 in FIG. 3) of the head part 2 from the upper end thereof. It has the space part 31a notched in the range. Thereby, the guide rail 20 (non-moving part 22) can be easily installed at a predetermined position of the frame 11 without interfering with the left and right end parts of the head part 2 installed in advance.

  Moreover, the arrangement relationship as described above has the effect of reducing the light leakage in the gaps S1, S2 between the left and right edge portions 11b or the right edge portion 11c of the screen 5 in the left-right direction and improving the light blocking performance. Can also 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 FIG. 9, the tip portions of the guide plates 32 and 34 overlap in the left-right direction with the same overlapping widths W2 and W3 as the side edges of the screen 5. Since the sprocket 3 and the chain cord 4 are provided at the right end portion of the head portion 2, the overlap width W3 at the right end portion of the screen 5 is shorter than the overlap width W2 at the left end portion. Yes.

  Here, as shown in the figure, when 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, the roll 8 is rewound all the way to the roll 8 in the minimum diameter state. The guide plates 32 and 34 of the non-moving portion 22 and the moving portion 23 are relatively close to the rear outer peripheral surface of the screen, that is, the back surface of the screen 5 at that time.

  Here, for example, when the space portion 31a is not formed in the guide base 31 of the non-moving portion 22, and the left and right lengths Lh and Ls of the head portion 2 and the screen 5 are set to be short, each guide is accordingly increased. Overlap widths W2 and W3 between the tip portions of the plates 32 and 34 and the side edges of the screen 5 are shortened. In this case, since the incident angles A1 and A2 of the external light entering from the gap between the edge portions of the guide plates 32 and 34 and the edge portion of the screen 5 become relatively large, the external light enters deeply forward in the gap S2. That is, light leakage increases (not shown).

  On the other hand, in the present embodiment shown in FIG. 9, since the space portion 31a is formed in the guide base 31 of the non-moving portion 22, the lengths Lh and Ls in the left and right directions of the head portion 2 and the screen 5 are increased accordingly. Thus, the overlapping widths W2 and W3 between the tip portions of the guide plates 32 and 34 and the side edges of the screen 5 can be secured sufficiently large. In this embodiment, such an arrangement relationship makes it possible to reduce the incident angles A1 and A2 of external light entering from between the edge portions of the guide plates 32 and 34 and the edge portion of the screen 5, and thus the gaps S1 and S2. It is possible to suppress the entrance of outside light to the front side, that is, it is possible to reduce light leakage and improve the light shielding performance.

<Effects of this embodiment>
As described above, in the present embodiment, the guide base 31 of the non-moving portion 22 includes the space portion 31 a for preventing interference with the end portion of the head portion 2. Thereby, the guide rail 20 (non-moving part 22) can be easily installed at a predetermined position of the frame 11 without interfering with the left and right end parts of the head part 2 installed in advance.

  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, since the guide base 31 of the non-moving portion 22 includes the space portion 31a, the overlapping width W2 between the tip portions of the guide plates 32 and 34 and the side edge portions of the screen 5 is obtained. Since W3 can be secured sufficiently large, entry of outside light to the front side in the gaps S1 and S2 can be suppressed, that is, light leakage can be reduced and light blocking performance can be improved.

  In the present embodiment, in particular, the width dimension Lh in the horizontal direction (left-right direction) of the head unit 2 is set to be longer than the width dimension Ls in the horizontal direction (left-right direction) of the screen 5. Thereby, in each guide base 31 and 33 of the non-moving part 22 and the moving part 23, interference with the screen 5 can be avoided reliably.

<Modifications>
The present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the spirit and technical idea of the present invention. Hereinafter, such modifications will be described in order. Note that, in each modified example described below, the same reference numerals are given to the same parts as those in the above embodiment, and the description thereof is omitted or simplified as appropriate.

(1) When the space area of the space part is variable In the above embodiment, the space area of the space part 31a formed as a notch in the guide base 31 of the non-moving part 22 is fixed. Is not to be done. For example, as shown in FIG. 9A, a slide base 35 having a shape similar to that of the guide base 31 in the longitudinal cross section is overlapped with the guide base 31 in the left-right direction.
Connect to move up and down. With such a configuration, the space area of the space portion 31a can be arbitrarily changed by manually adjusting the height position of the slide base 35.

  In addition, as shown in FIG. 9B, a base piece 36 having the same shape as the guide base 31 in the longitudinal direction is connected to the guide base 31 in a stackable manner. With such a configuration, the space area of the space portion 31a can be arbitrarily changed by stacking any number of base pieces 36.

  As described above, by making the space area of the space portion 31a variable, the space area can be optimally adjusted according to both ends of the head portion 2, and the guide base 31 of the non-moving portion 22 is installed accordingly. Stable installation is possible due to the large area.

(2) When the guide bases are connected so that the relative positions can be changed. In the above embodiment, the guide bases 31 and 33 of the non-moving part 22 and the moving part 23 are simply arranged in the vertical direction. It is not limited. For example, as shown in FIG. 10A, the guide bases 31 and 33 may be connected in the vertical direction via an insertion protrusion 39 provided at the lower end of the guide base 31 of the non-moving part 22.

  The two insertion protrusions 39 provided at the lower end of the guide base 31 of the non-moving part 22 are each formed in a size and shape that can be inserted into the guide base 33 of the moving part 23. These two insertion protrusions 39 are inserted into the guide base 33 of the moving part 23 from above, and are fixed between the left edge part 11 b or the right edge part 11 c inside the guide base 33. With the configuration as described above, the upper non-moving part 22 and the lower moving part 23 are connected so that their relative positions can be changed in the respective longitudinal directions.

  Here, in general, the vertical guide portion 21 is often made to order according to the height dimension of the frame 11, and the length dimensions of the non-moving portion 22 and the moving portion 23 are also individually determined for each lot. Is set. For this reason, manufacturing errors may occur in the lengths of the non-moving part 22 and the moving part 23, but the relative position of the non-moving part 22 and the moving part 23 can be changed in the longitudinal direction as described above. Therefore, it is possible to adjust the length dimension of the entire longitudinal guide portion 21 by absorbing the manufacturing error of such a length dimension (particularly, the error X when the length is shorter than the design value).

  The two insertion protrusions 39 may be provided at the upper end of the guide base 33 of the moving unit 23, or may be different for each of the guide bases 31 and 33 of the non-moving unit 22 and the moving unit 23. You may connect so that it may provide in the front-back position and to cross.

  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.
