Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to an internally illuminated sign that is installed at the entrance of a store, for example, for advertising or promotion.

(Prior art) Conventionally, as an internally illuminated sign, for example, JP-A-63-
As described in Publication No. 34583, a rectangular canvas stretching frame is removably attached to a rectangular body frame, and the four sides of the stretching frame are used to remove distortion and adjust the stretching of the poster canvas image. It is known that each canvas is provided with a canvas tensioning fitting that makes it possible to do so. In this case, the tension fittings that hold the ends of the poster canvas consist of a square adjustment bolt, a washer, a coil spring wrapped around the bolt,
Two types of canvas clamping bodies inserted into bolts,
It consists of a washer, a nut and a further canvas clamp, which are arranged in combination within the frame of the tensioning frame. Furthermore, a sign assembly with an illumination device is known, which is described in Japanese Patent Application Laid-Open No. 62-32489. In this case, the end of the sign sheet is held by attaching the sheet holder with a tightening bolt in a groove that opens outward in the frame member, and then inserts the sign sheet into a recess in the sheet holder that opens in the same direction as the groove in the frame member. The end portion of is held by a retainer.

(Problem to be solved by the invention) However, in the former case, there are many parts because the poster canvas tensioning hardware consists of three types of canvas clamping bodies: bolts, washers, coil springs, and nuts. The problem is that it takes time to assemble. Moreover, unless the parts are assembled and the nuts are tightened onto the bolts, the edges of the canvas cannot be held, and the canvas cannot be easily expanded.Also, since the bolts, nuts, and coil springs are used simultaneously, the canvas cannot be expanded when the nuts are tightened. There is a problem with too much tension. Also, in the latter case,
Since the seat holder is simply attached to the frame member with a tightening bolt, when the sign sheet is expanded or loosened by tightening or loosening the tightening bolt, the seat holder will not fit inside the groove of the frame member. There is a problem that it gets sticky and is difficult to move smoothly due to friction. Furthermore, in this latter case,
Since the concave part of the sheet holder that holds the edge of the sign sheet is opened outward like the groove of the frame member, when a strong tension is applied to the sign sheet, the sheet end easily moves out of the concave part of the sheet holder. There is a problem with this.

(Means for Solving the Problems) In order to solve the above problems, the internally illuminated sign of the present invention has a rectangular expansible frame in which a sheet-like material is stretched over the front of a box-like frame housing a built-in lighting device. is provided in a removable manner, and the main body frame material of the expansion frame is framed in a rectangular shape, and the holding frame material is arranged in a longitudinal holding groove opened to the outside of each frame material, and the main body frame material is Opposing side plate parts of the holding groove are inclined parallel to each other, an end of the front side plate part of the frame material is extended to form a free end, and a rib wall is opposed to the bottom plate part of the holding groove in parallel with the side plate part. A screw groove is provided between the rib walls, and a guide groove is provided between one of the rib walls and the side plate part, and the holding frame material is arranged so that the guide legs at both ends of the base plate are aligned with the side plate part of the holding groove, and one guide groove is provided between the rib walls. The leg is inserted into the guide guide groove, the opening of the groove in the inner longitudinal direction of the guide leg is arranged toward the bottom plate part of the retaining groove, and the tightening bolt passes through the base plate part and is screwed into the threaded groove. In this case, the end of the sheet-like material wraps around the free end of the main body frame member and is held in the groove by the fixing core member via the guide leg end of the holding frame member.
