JP 2009-138327 A

By the way, in the conventional blind as disclosed in Patent Document 1, the upper guide piece of the frame to which the rubber piece for gap shielding is attached is formed so as to rise upward at the rear of the frame, so that the bracket cannot be installed on the back side of the frame. Therefore, there is a problem that the shape of the bracket is limited.

SUMMARY OF THE INVENTION Accordingly, the present invention has been made in view of such problems, and an object of the present invention is to provide a blind having a bracket that can be used in a blind with a degree of freedom in shape. to provide.

In order to solve the above problems, according to the present invention, there is provided a support member to be placed in an opening of a building, a bracket for fixing the support member to a fixing surface of the opening, and one end of which is supported by the support member. and a shielding material hanging vertically from the support member, the blind comprising a gap prevention member capable of shielding a gap between the support member and the fixed surface, the gap prevention member comprising: A blind is provided, characterized in that it is arranged at a position in front of the bracket so as not to interfere with the bracket. The front position here is a position in front of the bracket when the blind is viewed from the front (the side on which the user operates the blind), and is a position that visually blocks the bracket. .

According to this configuration, since the gap prevention member is provided at a position forward of the bracket with respect to the support member, the shape of the bracket on the rear side of the gap prevention member does not matter. Therefore, it is possible to give flexibility to the shape of the bracket that can be used, such as a substantially L-shaped shape.

In addition, since the shape of the bracket that can be used can be given a degree of freedom, the support member can be attached and detached by the same construction as a normal blind that does not have a special gap prevention function. Furthermore, since the gap prevention member is provided in front of the bracket, when the support member is attached to the bracket, the bracket exposed above the support member can be covered.

Various applications are possible for the present invention. For example, the support member may be formed with a flange portion to be engaged with the bracket, and the gap prevention member may be provided on the upper surface of the flange portion. By using the upper surface of the brim portion to be engaged with the bracket, there is no need to provide a space for newly attaching the gap prevention member to the support member or to change the shape of the support member. Installation is possible.

Further, the support member may be formed to protrude forward from the bracket, and the gap prevention member may be provided on the upper surface of the protruded portion. Since the gap preventing member is provided on the upper surface of the overhanging portion of the front surface of the support member, the gap preventing member does not interfere with the bracket even when an external fitting type bracket is used, for example.

Further, an accommodating portion for accommodating the decorative cover may be formed on the front surface of the support member so as to protrude forward, and the gap preventing member may be provided on the upper surface of the accommodating portion. Since the clearance preventing member is provided on the upper surface of the accommodating portion formed on the front surface of the support member so as to protrude forward, the clearance preventing member does not interfere with the bracket.

Further, the gap preventing member may be provided on the fixed surface. By providing the gap prevention member on the fixing surface, the shapes of the bracket and the support member are not affected, so that the shape of the bracket and the support member that can be used can be given a degree of freedom.

Further, the gap prevention member may be formed integrally with the support member. By integrally forming the gap prevention member with the support member, there is no need to attach the gap prevention member separately, which leads to a reduction in construction time.

ADVANTAGE OF THE INVENTION According to this invention, the blind which can give flexibility to the shape of the bracket which can be used in the blind provided with the gap prevention member can be provided. Other effects of the present invention will also be described in the mode for carrying out the invention, which will be described later.
