Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a signboard frame for a fabric-covered signboard.

[Conventional technology]

Conventional signboards include those in which an acrylic face plate is fitted into a signboard frame, and those in which a fabric for the face plate is attached to the signboard frame.

[Problem that the invention attempts to solve]

Among the conventional signboards mentioned above, those with acrylic faceplates fitted with acrylic faceplates require additional acrylic plates to be added when the size of the signboard is increased, and the seams become noticeable and unsightly, and lighting fixtures are not included. If the sign is made thinner, it may reflect the shadows of the lighting fixtures or cause the acrylic face plate to become thermally deformed due to the heat from the lighting fixtures. Furthermore, if the signboard falls over or hits an obstacle, the acrylic face plate is likely to be damaged, resulting in a large amount of repair costs.

Among the above-mentioned conventional signboards, the above-mentioned problems with acrylic signboards can be solved by pasting fabric for the face plate, but it takes time and effort to paste the fabric to the signboard frame. It is difficult to apply the fabric in a state where it is pulled with uniform force, or in a state where it is taut. Problems such as the trouble of removing the fabric from the signboard frame and reattaching it to the signboard frame when replacing them due to malfunctions of lighting equipment such as fluorescent lights or wiring equipment built into the signboard. There is.

Further, regarding fabric-covered signboard frames, since the signboard is generally installed on a rooftop or outdoors, the fabric sheet stretched over the signboard frame is easily affected by the outside world such as wind, rain, and temperature. Therefore, for a frame structure on which signboard fabric is stretched as an outdoor installation, a frame structure is required that can hold the fabric in tension for a long period of time, as it sways due to wind pressure or other external pressure.

Regarding the fabric-covered signboard frame, Jikaisho received the prior application.
No. 62-167289, however, the frame structure of the mounting edge of the signboard fabric has drawbacks in its durability as an outdoor installation and in the strong holding effect of the fabric sheet.

The present invention aims to provide a fabric-covered signboard frame that can solve the above-mentioned conventional problems.

The movable frame pieces 3, 3', 5, 5' have an upper side 14 of a frame member 13 having a U-shaped cross section, for example as shown in the sixth figure.
A pipe 16 having a cut portion 15 at its tip edge.
A square pipe 18 is inserted inside the frame material 13, and an angle material 19 is used for the fixed frame 2, as shown in the sixth figure, for example. Use square or circular shapes. Then, with the bag-shaped edge 11 of the fabric 1 or 43, which has been inflated by inserting the core rod 12, inserted into the hooking part 17, the frame material 13 and the square pipe 18 are placed inside the angle material 19, and the angle material The adjusting screw bolts 7 are inserted through the frame material 13 and the square pipe 18 from some places on the upright piece 20 of the square pipe 18, and the nuts 21 are screwed into the tips of the screw bolts 7 that protrude inside the square pipe 18. The head 22 is attached to an upright piece 20 of the angle material 19.
The threaded bolt 7 is screwed in while the nut 21 is being pressed against it, and the pitch movement of the nut 21 caused by this screwing pulls the square pipe 18 and the frame material 13 toward the upright piece 20 of the angle material 19, thereby uniformly distributing the entire fabric 1. Apply tension and attach fabric 1. A receiver 23 is attached to each square threaded bolt 7, and a head 22 of each threaded bolt 17 exposed outside the angle member 19 and a portion between the angle member 19 and the frame member 13 are attached to each receiver 23. A ridge 25 formed to cover the opening 24 is attached. Further, a mounting member 27 for attaching the angle member 19 to a support stand, a support tower, etc. is attached to the bent piece 26 of the angle member 19.

The movable frame pieces 3, 3', 5, and 5' have cut portions along the diagonal portions of the movable frame body 28 formed of aluminum material, as shown in FIG. 7, for example, instead of the frame pieces shown in FIG. 6. 29, 29, and a circular cross-section groove 3
A hooking part 17 consisting of 0.0, 30 is provided, and inside the square pipe 28, there are partition plates 31, 32 facing each other at equal intervals in the vertical direction from the center, and a gap between the partition plates 31, 32.

In this case, the screwing of the adjusting screw bolt 47 from the fixed frame 44 to the movable frame piece 45 and the attachment of the ridge 48 are performed in the same manner as described for the sixth or seventh figure.

The present invention is not limited to the above-mentioned embodiments, but the fixed frame 2 is formed into various rectangular shapes such as polygons other than quadrangles, or the fabric 43 and fixed frame 44 are formed into various curves such as ellipses other than circular shapes. The movable frame pieces may be formed into a shape and arranged along the inside of the fixed frame, or the fixed frame 2 or the fixed frame 4 may be formed into a shape.
The design may be changed as appropriate, such as by molding 4 with a round pipe, or by changing the mounting position and angle of the hooking portion relative to the movable frame piece, and the shape of the hooking portion itself.

[Effect of idea]

Since the present invention is constructed as described above, the fabric for the face plate can be tensioned with a "ping" by the extremely simple operation of turning the adjustment screw bolt, and the tension of the fabric can be adjusted freely. In addition, when replacing lighting equipment such as fluorescent lights or wiring equipment built into the signboard, the fabric can be easily removed and attached, making it possible to construct fabric-covered signboards in a shorter time and at lower cost than before. In addition, large signs can be made without seams, and even if the sign falls over, the fabric will not tear, and the fabric is stretched with even tension, so even if there is a hole in one part of the fabric, the remaining fabric will not tear. There is no change in the tension of the fabric in that part. In addition, by attaching a push-edge to the fixed frame, you can improve the appearance of the sign frame, and it can be used not only for ordinary fabric-covered signs, but also for store tent signs, sleeve signs, stand signs, etc.
It has the advantage of being able to assemble various types of signboards, such as rooftop advertising towers.

A particular feature of this invention, compared to the above-mentioned known fabric-covered signs, is that it has a fabric tensioning and retaining force structure in which a circular core rod made of a hollow cylinder is inserted into the bag-shaped edge of the edge portion along which the sign fabric is stretched. This not only allows the fabric sheet to be stretched evenly and taut, but also absorbs the reaction force acting on the fabric sign due to external wind pressure, etc. through the flexibility of the hollow cylindrical core rod 12, exerting a strong spring effect and acting as an elastic repulsive force against external pressure and vibrations like a taut drum, with the advantage that the tensioning force of the sign fabric will not relax even with long-term use.

In addition, since the hooking portion for hooking the edge of the fabric is formed with a circular groove and a cut groove, it slides to accommodate the holding action of the cylindrical core rod inserted into the hooking portion, and the fabric sheet is prevented from sliding due to mutual friction. Effective in preventing wear and damage.

Therefore, it has a great structural advantage of increasing the durability of the signboard material. Furthermore, since the hanging parts are configured as a pair of frames in two diagonal locations on the movable frame via a partition plate, the signboard fabric can be stretched in several directions with one member, making it easier to install the signboard fabric. It has the advantage of helping to save labor and increase efficiency.
