Description

The present invention relates to a cloaking device.

As a conventional shielding device, there is one shown in Japanese Patent Application Laid-Open No. 5-84498 (Patent Document 1). The guide rail of the shielding device disclosed in the same document is a slit in which the end of the screen engages in a retaining state in the main rail provided with a guide groove in which the end of the aluminum bottom bar fits in the length direction. Equipped with an inner rail with. Then, as a configuration of the main rail, guide grooves made of synthetic resin are attached to the tips of both side walls of the rail main body having a groove-shaped cross section made of aluminum, so that guide grooves are provided between these guide members. Is disclosed.

According to this, the inner rail is placed inside the main rail of the main rail with an elastic member urging in the direction in which the tension in the width direction of the screen increases, and is synthesized at the tips of both side walls of the main rail.

Jikkenhei 5-84498 Gazette

However, the member constituting the main rail is composed of a rail main body and a guide member, and when the main rail is attached to the fixed surface, a configuration in which an extension piece formed on the outer side of the side surface of the main rail is screwed is disclosed. However, it cannot be installed depending on the dimensions of the fixed surface such as the window frame. It is possible to screw the bottom surface of the main rail without forming an extension piece, but in that case, screw only the main rail of the main rail, then incorporate the inner rail, and finally both guide members. There was a problem in workability due to the large number of parts required.

Therefore, the present invention has been made in view of such a problem, and an object of the present invention is to provide a shielding device capable of improving workability.

In order to solve the above problems, according to the present invention, the shielding device includes a support member that supports the shielding material so as to be openable and closable, and guide rails that guide both ends of the shielding material. The rail is fixed to a fixed surface by a fastener, and a base rail whose surface facing the fixed surface is open, and an inner rail which supports an end portion of the shielding material and is built in the base rail. The inner rail is characterized in that a slit into which an end portion of the shielding material is inserted and an opening having a size through which the fastener passes and communicating with the base rail are formed. , A cloaking device is provided.

According to this configuration, by forming an opening in the inner rail that is large enough for fasteners (for example, screws) to pass through and communicates with the base rail, the inner rail is installed in the base rail and the base is passed through the opening. The rail can be fastened to the fixed surface with fasteners, reducing the number of parts and improving workability. Further, since a retrofit guide member as disclosed in the conventional Patent Document 1 is not required, the degree of freedom in designing the base rail is increased, and the rail dimensions (for example, the depth direction of the rail corresponding to the width direction of the shielding material) are increased. ) Can be reduced, so that the open area of the space where the shielding device is installed can be increased.

The present invention has various applications. The following application examples can be combined as appropriate.
For example, the opening may be formed at a position separated from the slit. By forming the opening at a position away from the slit into which the end of the shielding material is inserted, the movement of the shielding material is not affected.

Further, the opening may be formed so as to straddle the slit. By forming the opening so as to straddle the slit, it is not necessary to increase the size of the base rail, and the existing base rail can be used.

Further, the connecting portion of the opening with the slit may be tapered or R-shaped. When the opening is formed so as to straddle the slit, such a configuration makes it difficult to affect the movement of the shielding material. That is, because the connecting portion of the opening with the slit is tapered or R-shaped, when the shielding material passes through the opening, it is caught at the boundary between the opening and the slit, and the screen end (zipper) is engaged. It is possible to prevent the slit from coming off or opening / closing failure.

Further, in the inner rail, one or two or more first inner rails having an opening and one or two or more second inner rails having no opening are arranged in the length direction. May be good. According to such a configuration, the first inner rail (for example, a rail member cut into a short length) is arranged according to the position of the hole for fastening the fastener formed in the base rail, and the second inner is in the other portion. By arranging the rail (for example, a rail member cut longer than the first inner rail), it is not necessary to set the processing position of the opening of the inner rail for each product size (height). The position of the opening can be easily adjusted at the mounting site. It also facilitates transportation. In this way, the workability can be further improved.

Further, a gap prevention member may be provided in the base rail so as to come into contact with at least one surface of the front surface and the back surface of the shielding material closer to the open surface than the inner rail. By providing a gap prevention member in the base rail closer to the surface that is open than the inner rail, it is possible to prevent light leakage from the opening. The gap prevention member may be provided at another position in order to improve the installation location and workability of the shielding device.

According to the present invention, there is provided a shielding device capable of improving workability. Other effects of the present invention will also be described in the embodiments for carrying out the invention described later.
