[Prior art]

 Ancillary items attached to buildings need to be able to flexibly handle a wide variety of forms of buildings. Ancillary products that can satisfy such demands have greater flexibility in application to buildings, and the providers that provide them are expected to expand their sales channels.

For example, in events such as plays, competitions, and lectures, blackout curtains that block out sunlight so that effective lighting is realized are no exception. In recent years, theaters, gymnasiums, public halls, and the like often employ designs with a strong presence and originality, and various measures are required for blackout curtains.

[0004] For example, in a so-called roll screen type blackout device in which a blackout curtain is wound up and stored in a roller pipe and pulled out to open and close, it is essential to prevent light from leaking at the left and right ends of the blackout curtain. In addition, concealing members (commonly known as track guides) each having a substantially C-shaped or substantially U-shaped cross section having an opening formed on the surface thereof are arranged one by one on each of the left and right sides of the blackout curtain with the openings facing each other. It is generally considered effective to insert the end into the concealing member.

The slide bar has both ends inserted into the concealing member through the opening on the surface, so that the up and down movement is guided by the concealing member. Therefore, by simultaneously rotating and reversely rotating the roller pipes (2) and (3), the slide bar moves up and down along the concealing member via the tension member, and the blackout curtain automatically opens and closes.

[0007] Such a slide bar is a member having a fixed length attached to one end of a blackout curtain. Therefore, in the case (1a) and (1b) as shown in FIGS. 7 <a> <b> <c>, the interval between the two is different between the upper end side and the lower end side (specifically, upward. The slide bar of a certain length may be distorted and fall to one of the left and right concealing members near the part where the dark curtain is twisted and comes off the concealing member as described above. become.

The invention of this application has been made in view of the above circumstances, and is parallel to each other when viewed in plan and from the front, but the positions of the upper and lower ends are shifted back and forth, and are different from each other. When closing the space between a pair of sidings inclined at an angle with a blackout curtain, the slide bar can be moved smoothly regardless of the position of the sidings, and the blackout curtain is twisted by the positioning of the sidings. Another issue is to provide a roll-screen type blackout device that does not leak light from the left and right ends of the blackout curtain.

In the blackout device of the present invention, the position of the roller pipes (2) and (3) is not limited to the lower end portions of the masts (1a) and (1b) shown in FIG. It is. In this case, the connection between the slide bar (10) and the tension member (5) is, as described above, taken into consideration, for example, that the tension member (5) is not entangled with the blackout curtain (4) and the slide bar (10). Above.

Further, as shown in FIGS. 2 and 3, the blackout device according to the invention of the present application includes a light blocking member (19) having flexibility and light blocking properties, which hangs on the upper surface of one end of the blackout screen (4). Prepare. The material of the light shielding member (19) is not particularly limited as long as it has flexibility and light shielding properties. The light shielding member (19) can be made of the same cloth as the blackout curtain (4), although it can be made of soft plastic, rubber or the like. Further, as shown in FIG. 3, the light-shielding member (19) has an end opposite to the blackout curtain (4) on the guide rail (8) or the inner facing surface (7) of the erections (1a) (1b). In this case, the light shielding member (19) hangs from above the guide rail (8) to the upper surface of one end of the blackout curtain (4), as shown in FIGS.

In addition, the light-shielding member (19) is a winding means such as a roller pipe other than the roller pipe (2) capable of winding and drawing out the blackout curtain (4) shown in FIG. It can be installed side by side with a roller pipe (3) or a roller pipe (2) (3) that can take up and deliver the member (5), and can rotate and reverse rotate at the same time as the roller pipes (2) (3). It can be provided on a separate roller pipe or the like at the time of winding and drawing. In the latter, one end of the light shielding member (19) can be attached to the slide bar (10), and the light shielding member (19) can be pulled out from the winding means and wound up with the movement of the slide bar (10). .

In addition, the winding deviation of the light shielding member (19), which may occur at the time of winding, is adjusted by the winding means in accordance with the position of the end of the light shielding member (19) on the side of the blackout screen (4). This can be prevented by arranging a winding prevention member which can be used.

In the blackout device of the present invention having the above-described configuration, the roller pipes (2) and (3) are simultaneously rotated or reversely rotated by the operation of the electric drive unit, and the slide bar (5) is connected via the tension member (5). When the 10) is moved along the guide rail (8), and the direction bars (1a) and (1b) are closed with the blackout curtain (4), the slide bar (10) does not fall off the guide rail (8) smoothly. Go to This is because, as described above, the sliding members (8) at the left and right ends of the slide bar (10) are pressed outward by the elastic members (16) incorporated in the slide bar body (15). Since the inclination can be made with respect to the main body (15), even if the interval between the inner facing surfaces (7) of the erections (1a) and (1b) is enlarged or reduced, the sliding body (8) is not moved. In the two guide rails (8) provided on the inner facing surfaces (7) of the erections (1a) and (1b), a state in which the sliding can be smoothly performed such as an upright state as illustrated in FIG. This is because the slide bar main body (15) can be stably maintained, and the slide bar main body (15) is arranged without being offset by either of the left and right guide rails (8). This non-uniform arrangement of the slide bar body (15) is also effective in preventing unwinding when the blackout curtain (4) is wound around the roller pipe (2).

In the blackout device according to the invention of the present application, when closing the screens (1a) and (1b) with the blackout screen (4), the screens (1a) and (1b) are arranged as described above. Even when the slide bar (10) is pulled out with the movement of the slide bar (10) and twisted in the blackout curtain (4), light does not leak from both left and right ends. This is because, as described above, the left and right side ends of the blackout curtain (4) are supported from below by the support plate portion (11) of the guide plate (14). 4) is greatly twisted and partially disengaged from the support by the support plate (11) (in the embodiment of FIG. 1 this can occur at the top of the framings (1a) (1b)). This is because the light-shielding member (19) having flexibility and light-shielding properties that hang down on the upper surface of each of the left and right side ends hangs down, so that light is blocked by the light-shielding member (19).

Therefore, the blackout device according to the invention of the present application is parallel to each other when viewed in a plan view and from the front, but the position of the upper and lower ends is shifted back and forth, and each of the two is inclined at a different angle. When closing between the stands (1a) and (1b) with the blackout curtain (4), even if the blackout curtain (4) is twisted due to the arrangement of the blackboards (1a) and (1b), the light from both the left and right ends of the blackout curtain (4). Can be prevented from leaking.

As described above, the blackout device according to the invention of the present application is parallel to each other when viewed in a plan view and when viewed from the front, but the positions of the upper and lower ends are shifted back and forth, and each pair is inclined at a different angle. This is a roll screen type blackout device that can automatically open and close the blackout curtain (4) between the blackout curtains (1a) and (1b). The smooth movement of the slide bar (10) is possible irrespective of the arrangement positional relationship, and even if the black curtain (4) is twisted due to the positional arrangement of the pillars (1a) and (1b), the movement of the black curtain (4) can be improved. No light leaks from the left and right ends.

In the blackout device according to the invention of the present application, the slide bar (10) can be more specifically configured as shown in FIG. 4 and FIG. That is, the slide bar (10) can include a shaft (20) for moving the slide bar body (15) forward and backward in the longitudinal direction. In order to make this possible and to incorporate an elastic member (16) such as a spring, a through hole (21) extending in the longitudinal direction can be formed at the center of the slide bar body (15). By inserting the elastic member (16) into the through-hole (21), the elastic member (16) can be arranged inside the one end of the slide bar body (15) and built in. In addition, the elastic member (16) needs to have a built-in position. Therefore, in the embodiment shown in FIGS. 4 and 5, a screw (22) is fixed vertically to the through hole (21) at a predetermined position by using a washer (23) or the like, whereby the elastic member (16) is fixed. ) Is specified. Therefore, one end of the elastic member (16) comes into contact with the screw (22) by being built into the slide bar body (15), and an elastic force can be generated. The shaft (20) can be inserted into the through hole (21), for example, by contacting the elastic member (16) incorporated as described above at the rear end. In addition, the shaft (20) has a length such that the tip thereof protrudes outward from the end face of the slide bar body (15), and a spherical body (24) can be provided at the tip. The spherical body (24) can be inserted into a round hole (25) formed at the center position of the sliding body (9) at both right and left ends of the slide bar (10).

For example, with the above configuration, the sliding members (9) at the left and right ends of the slide bar (10) are pressed outward by the elastic member (16) built in the slide bar body (15), and 6, it is possible to tilt the slide bar body (15).

In this case, in the blackout device according to the invention of this application, as shown in FIGS. 4 and 5, in order to prevent the shaft (20) from falling off from the slide bar main body (15), the shaft ( 20), an elongated hole (26) extending in the longitudinal direction and penetrating vertically is formed in the opening, and is similar to, for example, a screw (22) and a washer (23) for defining a built-in position of the elastic member (16). The stopper (27), which can be formed as described above, can be vertically inserted into the elongated hole (26) to stand upright on the slide bar body (15). With this configuration, the abutment of the stopper (27) with the left and right ends of the elongated hole (26) with which the stopper (27) abuts restricts the reciprocation of the shaft (20) in the slide bar body (15). The stopper (27) is prevented from falling off from the slide bar body (15) at either left or right end of the long hole (26) with which the stopper (27) comes into contact.

As described above, when the light shielding member (19) is provided on the winding means so as to be able to be wound up and pulled out, the end opposite to the blackout curtain (4) is shown in FIGS. The shaft (20) is fixed at an appropriate position near the sliding body (9) using a fixing member, and the end on the side of the blackout curtain (4) is provided in the longitudinal direction on the upper surface of the slide bar body (15). It can be fixed to the sliding member that slides smoothly in the same direction as the shaft (20) advances and retreats in the lateral groove (28), which can be screwed or bonded. As a result, the sliding member slides in the lateral groove (28) as the shaft (20) advances and retreats. As a result, the light shielding members (19) are always located on the left and right ends with respect to the black screen (4). (4) It can surely hang down on the upper surface of the left and right side end portions. The fixing member can be fixed and integrated with the end of the sliding member on the side of the sliding body (9). By providing such a fixing member and a sliding member, the same cloth as that of the blackout curtain (4) can be used as the material of the light shielding member (19) even in the winding and drawing method.
