[0002]

2. Description of the Related Art Conventionally, there is a building having a top light structure in which a sash in which a glass plate is fitted is attached to the outdoor side of a three-dimensional truss structure frame to improve indoor lighting. In a building structure covered with a toplight, natural light can be sufficiently taken indoors.However, with the recent increase in size and complexity of buildings, the glass area of the toplight has increased and the dazzling sunlight Depending on the application, there were cases where it was desired to block natural light, such as when the temperature inside the pod increased. In order to respond to such needs, in a conventional space structure including a space truss structure frame, a method has been adopted in which a light-shielding film is developed along the lower chord of the space truss to block natural light that enters the room.

[0003]

However, in a conventional top light sash provided with a light-shielding film, a light-shielding film unit is attached to the lower chord of the three-dimensional truss structure frame, so that a part of the internal space is partitioned by the light-shielding film. As a result, there was a problem that a sufficient space could not be secured near the ceiling. Also,
Since the light-shielding film employs a sheet-like cloth material, the light-shielding film extended between the winding devices may bend in the middle, so that not only the appearance is poor but also the opening and closing may be hindered.

[0004]

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned circumstances, and has been made in order to solve these problems. In a top light sash forming a roof of a building by fitting a panel, a light shielding curtain unit having a film body that can be freely opened and closed and wound up and down is provided on the indoor side of the top light sash. In the upright position, a guide groove for guiding the film body is provided, and a support groove for supporting a deflection preventing roller for supporting the bending of the film body is provided. On the other hand, the bending prevention roller is slidably fitted in the support groove. An end member having a support portion and a screwing portion screwed to the fastener is provided, and the support portion is fastened to the support groove by screwing of the fastener. Attach the prevention roller Can.

[0005] In the above means, it is preferable that the support portion and the threaded portion formed on the end member are formed of bolts, and the fastener is formed of a nut.

Next, an embodiment of the present invention will be described with reference to the drawings. In the drawings, reference numeral 1 denotes a sash for a top light constituting a roof of a building structure such as an art museum or a gymnasium. The sash 1 for a top light has a plurality of hollow pipes T1 and spherical joints T2 connected in a chain. A ridge 2 attached in parallel to the truss frame T at a predetermined interval, a blind 3 erected on the ridge 2, a glass panel G fitted into a frame formed by the two members 2, 3, and The glass panel G is constituted by an eye plate 4 for holding the four circumferences. On the indoor side of the sash 1 for the top light, a flexible film body S is provided so as to be movable in parallel with respect to the glass panel G, so that the roof can be switched between a lighting state and a light shielding state. I have.

The cubic member 2 is formed of a rectangular cylindrical aluminum mold, and has a convex portion 2a and a glass support piece 2b at the upper part.
However, blind support pieces 2d and 2e, light shielding curtain guide grooves 2f, and deflection preventing roller support grooves 2g are formed on both left and right side surfaces. On the other hand, the blind 3 is formed of a rectangular cylindrical aluminum material, and has an upper portion 3a and a glass support piece 3b. Furthermore, the key plate 3
3 is fitted in the fitting groove 3d.

[0008] The erection of the blind 3 on the cubic 2 is performed by dropping a blind into a notch 2 h formed at a predetermined pitch on the cubic 2, and forming step portions formed at both ends of the blind 3. 3e and 3f are supported by the blind support pieces 2d and 2e, and the key plate 33 fitted to the end of the blind 3 is fitted into the key plate fitting groove 2i of the cubic 2, and then screws are fastened. As a result, the partition 2 is fixed. A glass panel G is fitted into the frame formed by the cubic 2 and the blind 3, and four sides thereof are supported, but the upper surface is pressed by the eye plate 4. The eye plate 4 is made of a flat plate-shaped member, and locking pieces 41 and 42 are formed on the lower surface thereof in the same direction. Further, a face plate mounting bracket B having locking pieces B1 and B2 opposite to the locking pieces 41 and 42 is provided on the cubic 2 and the eyelet 3 via protrusions 2a and 3a via rubber heat insulating material. Fixed.

As shown in FIG. 5, the fitting of the eye plate 4 is performed by a fitting member 45 having a flexible inclined projection 45a in a gap formed between both locking pieces B1 and B2 of the eye plate mounting bracket B. Into the projections 45a of the fitting material,
Is pressed and slid to lock the locking piece B2 of the eye panel mounting bracket B. Then, the pressing of the inclined projection 45a is released and the inclined projection is restored to the upright posture, so that the lateral movement of the locking piece 41 of the eye panel 4 is restricted. Thereafter, the glass panel is completely fixed by injecting a sealing material into a gap generated between the eye panel 4 and the glass panel G.

Next, a light shielding film unit according to an embodiment of the present invention will be described. A light-shielding film unit Y is attached between the eyes 3 and 3, and the light-shielding film unit Y includes a flexible film body S, a film winding unit Y1, and a wire winding unit Y2. . The film body S is made of a sheet material such as polyester or glass fiber whose surface is coated with vinyl chloride, and is a material excellent in fire resistance and durability. Film winding unit Y
1 is a film winding pipe P1 to which one end of the film body S is fixed,
A winding device M1 (not shown) for driving the film winding pipe P1 to rotate forward and backward, and a case C1 for accommodating these devices. On the other hand, the wire winding unit Y2 includes a wire winding pipe P2 to which one end of the wire W connected to the leading member 5 is fixed, and a winding device M2 (not shown) for driving the wire winding pipe P2 to rotate forward and reverse. And a case C2 for accommodating them. The leading member 5 is made of an aluminum material having a substantially elliptical cross section.
Can be attached. The leading member 5 is fitted in a light-shielding film guide groove 2f formed on the cubic 2, and can be slidably moved on 2f based on driving of the winding devices M1 and M2.

Next, the opening / closing operation of the light shielding film unit Y will be described. Normally (at daylighting), the film body S is housed in the case C in a state of being wound up by the film winding pipe P1, but when it is desired to block natural light, the winding device M2 is moved in a predetermined direction (FIG. Then, the wire W is wound around the wire winding pipe P2.
Then, the leading member 5 connected to the end of the wire moves leftward in the figure while traveling on the light-shielding film guide groove 2f, and the film body S also moves in the same direction in conjunction with the movement, and all the wires are moved. A known point such as a limit switch detects the time when the wire is wound, and stops driving the wire winding device M2. Through a series of operations described above, the film body S is deployed on the indoor side of the top light, and can block the incidence of natural light. On the other hand, in the daylighting state, the film winding device M1 may be rotated clockwise in the drawing to wind the film S around the film winding pipe P1, and the stop control and the like are the same as the closing operation. .

Since the film body S is a very thin sheet-like cloth material, the film body is bent during the movement of the film body, and the bent film body may interfere with the frame or the like and hinder opening and closing. Therefore, in order to apply tension to the film body S, when winding and rewinding the film body, one of the winding devices is driven and at the same time a slight braking force is applied to the other winding device. By forcibly rotating the take-up device, the film is always opened and closed while tension is applied to the film. Further, even after the film body is unfolded, the film can be further tensioned by slightly rotating the film-side winding device in the winding direction (clockwise in the drawing).

However, when the distance between the two units Y1 and Y2 is very large, that is, when the length of the film body S is long, the film bending cannot be prevented only by applying tension by the motor. Further, since the film is forcibly pulled, the film may be stretched or deformed, or the joint of the film may be overloaded, causing damage or wrinkling of the film. Therefore, a bending prevention roller 6 for supporting the bending of the film is provided immediately below the film body S. The deflection preventing roller 6
Is composed of a central shaft 61, a rotating shaft 62 rotatably attached to the central shaft 61, and end members 63, 63 attached to both ends of the central shaft 61.

A bolt 7 is attached to the end member 63, and a bolt head of the bolt 7 is slidably fitted in a deflection preventing roller support groove 2 g formed on the cubic 2, and a nut 8 is provided. The fastening is fixed to the deflection preventing roller support groove. When attaching the deflection preventing roller 6 to the cubicle 2, the bolt 7 is attached to the end member 63 with the nut loosely tightened in advance, and the head of the bolt 7 is fitted into the support groove 2g of the cubicle 2. Then, after sliding to a desired position, the nut 8 is fastened and fixed to the support groove 2g.

[0015]

As described above, the present invention is constructed as described above.
Since the light-shielding state can be switched, the load of lighting and air conditioning can be reduced by effectively utilizing the light and heat generated by sunlight. In addition, since the light-shielding film is supported by the guide grooves formed in a cubic manner, it does not partition the building space, so that the upper space of the building can be effectively utilized. Further, since the deflection preventing roller is configured to be movably supported and fixed in the support groove formed in a cubic manner,
The roller can be fixed while freely adjusting the mounting position of the deflection preventing roller.
