 FIG. 1 is a partial cross-sectional view showing a usage state of a signboard device A according to an embodiment of the present invention. This signboard device A has a sheet tensioning frame 2 in which a frame member made of aluminum is framed into a rectangular tubular shape. The seat tension frame 2 is provided with a front flange portion 22 projecting laterally outward and directed obliquely forward at a front end portion of a rectangular tubular base wall 21, and is substantially perpendicular to a rear end portion of the rectangular tubular base wall 21. A rear flange portion 23 is provided which projects laterally to the outer peripheral side, and an intermediate flange portion 24 which projects substantially outwardly to the outer peripheral side is provided at an intermediate portion in the front-rear direction of the rectangular tubular base wall 21. The base wall 21, the intermediate flange portion 24, and the rear flange portion 23 form a seat fixing recess B, and the rectangular tubular base wall 21, the intermediate flange portion 24, and the front flange portion 22 form a seat tension recess. C is formed. The front flange portion 22 and the intermediate flange portion 24 are provided with curved surfaces 22a and 24a at their front end portions, respectively, and the rear flange portion 23 is provided at its front end portion with an engaging plate portion 25 extending rearward. Further, the rectangular tubular base wall 21 has first and second predetermined positions between the front flange portion 22 and the intermediate flange portion 24 and a predetermined portion between the intermediate flange portion 24 and the rear flange portion 23, respectively. Bolt through holes 26 and 27 are provided, and each of these bolt through holes 26 and 27 is formed as a screw hole. Further, the surfaces 24b, 23b of the intermediate flange portion 24 and the rear flange portion 23 which are opposed to each other are slightly inclined outwardly at a predetermined opening angle.

Reference numeral 3 denotes a compression member, which has a bottom plate portion 31 and a pair of rising plate portions 32, 32 provided at both ends of the bottom plate portion 31 in the width direction. It is set to be slightly wider than the minimum width (interval between the root portions of the collar portions 24, 23) between the intermediate collar portion 24 and the rear collar portion 23 in the installation frame 2 and a pair of rising plates. An opening angle (the same or a large opening angle) in which the outer surfaces 32a, 32a of the parts 32, 32 are not smaller than the opening angle between the surfaces 24b, 23b which oppose each other between the intermediate flange 24 and the rear flange 23. It is slanted to the outside. The outer surfaces 32a, 32a of the pair of rising plate portions 32, 32 are provided with a large number of pointed convex surfaces extending in the longitudinal direction. The pressing member 3 has a length that matches the length of one side of the sheet tensioning frame 2, and the bottom plate portion 31 has first and second loosely-fitting holes at predetermined positions. A bolt through hole 35 is formed. A pressing member 4 has the same shape and configuration as the pressing member 3 as the pressing member 4. Reference numeral 41 is a bottom plate portion, 42 and 42 are a pair of rising plate portions, and 45 is a second bolt through hole.

Reference numeral 6 denotes a second tightening bolt, which has a head portion 61 and a screw shaft portion 62, and the screw shaft portion 62 is formed in the rectangular tubular base wall 21. It can be screwed into the hole).

Next, an example of a work procedure for tensioning the flexible sheet 1 will be described. The seat 1 is arranged so as to cover an opening 29 surrounded by the rectangular tubular base wall 21 of the sheet tensioning frame 2, and an outer peripheral portion 18 thereof is provided at a front flange portion 22 of the sheet tensioning frame 2. It is wound around the curved surface 22a, and the outer peripheral portion 18b is arranged on the outer peripheral side of the rectangular tubular base wall 2 with respect to the winding portion 18a. Next, as shown by a phantom line in FIG. 2, the screw shaft portion 52 of the first tightening bolt 5 is inserted into the first bolt through hole 35 of the pressing member 3, and the screw shaft portion 52 is attached to the seat 1. It is screwed into the first bolt through hole 26 through the opening 15 formed in the above, and the constricting member 3 is tightened with the first tightening bolt 5 as shown by the solid line in the figure, and fitted into the seat fixing recess B. . As a result, the outer peripheral portion 18b of the seat 1 is clamped and fixed between the pressing member 3, the rectangular tubular base wall 21 of the seat fixing recess B, the intermediate flange 24, and the rear flange 23. To be done. In this case, the outer peripheral side portion 18b of the seat 1 is connected to the rising portion 32 on one side of the pressing member 3 at a stage in which the pressing member 3 is being fitted between the intermediate brim portion 24 and the rear brim portion 23. It is sandwiched and fixed between the intermediate collar portion 24 and between the rising portion 32 and the rear collar portion 23 on the other side. Therefore, the outer peripheral portion 18b of the sheet 1 includes the rising portion 32 on one side, the bottom plate portion 31, the rising portion 32 on the other side of the pressing member 3, the intermediate flange portion 24 of the frame 2 for seat tension, the rectangular tube. The shape base wall 21 and the rear flange portion 23 are clamped to each other, and the pointed convex surfaces provided on the outer surfaces 32a and 32a of the rising portions 32 and 32 are firmly fixed in a state of being bitten.

The step of fixing the entire circumference of the outer peripheral side portion 18 b of the sheet 1 to the sheet tension frame 2 by using the pressing member 3 is a step of pretensioning the sheet 1. Therefore, the seat 1 may be loosened to some extent. If the outer peripheral side portion 18b of the seat 1 is securely fixed in the preliminary tensioning process as described above, the work described below, that is, the work of finally tensioning the seat 1 is facilitated.

The work of finally tensioning the sheet 1 is performed as follows, for example. That is, as shown in FIG. 3, the screw shaft portion 62 of the second tightening bolt 6 is inserted into the second bolt through hole 45 of the pressing member 4, and the screw shaft portion 62 is passed through the opening 16 formed in the seat 1. The second bolt through hole 27 is screwed in, the pressing member 4 is tightened, and the seat tension recess C is fitted. As a result, the sheet 1 that has been pretensioned is pressed by the pressing member 4 and the tension gradually increases, and the sheet 1 is sandwiched between the pressing member 4 and the rectangular tubular base wall 21 as shown in FIG. The seat 1 is finally tensioned when it is found. Such a final tensioning step can be performed easily because the outer peripheral portion 18b of the sheet 1 is securely fixed as described above in the preliminary tensioning step as described above, and the sheet 1 is not wrinkled. Roughness is less likely to occur. The pressing member 4 does not necessarily have to be tightened up to the rectangular cylindrical base wall 21, and it is desirable that the pressing member 4 be stopped at a position where the sheet 1 is in a final tension state.

As shown in FIG. 1, after the sheet 1 is stretched, the cover material 7 is attached so as to cover the periphery of the sheet stretching frame 2. The front end portion of the cover member 7 extends to the front edge portion of the sheet tensioning frame 2 to form a signboard edge frame portion 71.

In this embodiment, the pressing member 3 and the pressing member 4 are the same, but different ordinary members may be used. Further, in this embodiment, the first and second bolt through holes 26 and 27 of the rectangular tubular base wall 21 of the seat tension frame 2 are screw holes, and the bolt through holes of the pressing member 3 and the pressing member 4 are used. Is a loose fitting hole, the first and second bolt through holes 26 and 27 of the rectangular tubular base wall 21 are loose fitting holes, and the bolt through holes of the pressing member 3 and the pressing member 4 are screw holes. In this case, the first tightening bolt 5 and the second tightening bolt 6 can be attached to the first and second bolt through holes 26 from the inside of the rectangular tubular base wall 2. , 27, the sheet 1 is inserted, and is screwed into the bolt through holes (screw holes) of the pressing member 3 and the pressing member 4. The openings 15 and 16 formed in the sheet 1 can be formed by making cuts in the sheet 1, for example.

[Effect of device]

 In the signboard device of the present invention, since it is possible to pretension the sheet and finally to tension it, the workability in tensioning the sheet is improved, and at the same time, the sheet is tensioned so as not to wrinkle or wavy. It will be easier to do. Further, in both the pre-tensioning and the final tensioning, the outer peripheral portion of the sheet is pulled evenly by the action of the pressing member and the pressing member, so that wrinkles and waviness are less likely to occur in the tensioned sheet, Further, since the force due to the tension is also dispersed by the pressing member, the sheet tension frame is not deformed.
