Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to an improvement in the fixing structure of a display sheet for a signboard.

<Prior Art> There is a tendency for so-called internally illuminated illuminated signboards, which have a light source inside and illuminate external advertisements from this light source, to become larger. With this trend toward larger sizes, there is an increasing need for illuminated signboards with large display areas that cannot be formed using hard translucent plastic boards (eg, acrylic boards).

As a material for the above-mentioned purpose, a flexible translucent sheet in which a mesh-like polyester fiber fabric or the like is integrated as a base material between layers of a soft vinyl sheet is generally used.

When using the above-mentioned sheet as an advertisement display section, it is necessary to stretch and fix the sheet at the signboard installation site.

To solve this problem, an eyelet was driven into the periphery of the sheet, a hook-shaped metal fitting was hooked onto the eyelet, and the other end of the metal fitting was fixed to a frame provided around the light source.

As such metal fittings, metal fittings such as turnbuckles, which can adjust the tension, were used.

Those using the above-mentioned turnbuckles require processing such as attaching a plurality of metal fittings such as eyelets to the periphery of the seat. Also, multiple metal fittings such as turnbuckles are required. Therefore, a large number of metal fittings are required, and
It took time and effort to tighten each metal fitting individually and to apply even tension to the sheet.

For the purpose of eliminating the need for such a large number of metal fittings and the trouble of adjusting each metal fitting, the applicant of the present application previously filed an application as Japanese Utility Model Application Publication No. 171532/1983. As shown in Fig. 6, this is done by using a locking tool that extends both sides of the flexible sheet b into the housing a arranged on both sides or one side of the main body frame. A first locking piece c that can be wound around the flexible sheet b is made up of a hollow cylindrical body e having a notch d and a protrusion f, while a second locking piece g around which the flexible sheet b can be wound.
This is a fastening tool for spreading a flexible sheet, characterized in that it has several protrusions h in the longitudinal direction of a cylinder, and the protrusions can be engaged with the notches.

A suitable structure of a signboard using such a fastener will be explained using FIG. 8. Signboard i has vertical frame j
and the horizontal frame k to form a rectangular shape. A suitable light source such as a fluorescent lamp is disposed inside the frame constituted by the vertical frame j and the horizontal frame k (not shown).

The above-mentioned flexible sheet b, that is, the advertising display sheet is stretched on the surface of the frame. Therefore, in order to hold the ends of the flexible sheet b in a tensioned state, the above-mentioned casing a is provided along the vertical frame j and the horizontal frame k,
The previously described extension locking device is used.

<Problems to be solved by the invention> However, in the case of the flexible sheet extension fixing device provided in such conventional illuminated signboards, the housing a
When attaching the first locking piece c to the housing, it takes time and effort to push the protrusion f into the housing a because it is formed in a size that will not fall off after installation. When removing the first locking piece c from the casing a, it was difficult to take it out (the operation shown in Fig. 7 was difficult to perform. In Fig. 3, in order to avoid complication of the drawing, The second locking piece g and flexible sheet b are omitted.Usually the first locking piece c
With the flexible sheet b being fixed, the first locking piece c is attached to or removed from the housing a).

The present invention aims to solve the above problems.

<Means for Solving the Problems> Accordingly, the present invention includes an appropriate number of holders 1 that hold the ends of a signboard display sheet, and a holder 1 that is formed separately from the holders 1 and that receives each holder 1. It has a receptor 2. The receptor 2 is a long strip having a length corresponding to the end width of the signboard display sheet, and is also a box with a hollow interior. It has an opening 4 leading into the hollow part 3. Moreover, the above-mentioned holding body 1
has a holding part 5 that holds the edge of the signboard display sheet, and a jaw piece 6 that protrudes outward from an appropriate position on the surface of the holding part 5, and has an inner hollow part of the receptor 2 from the opening 4. By being inserted into receptor 3, it is received by receptor 2.

This jaw piece 6 holds the holding part 5 as a reverse hook so that it does not fall out from inside the receptor 2 by having its tip 7 abut against the peripheral edge 8 of the opening 4 of the receptor inside the receptor 2. It is something. Further, the tip 7 of the jaw piece 6 has a first fulcrum 9 that protrudes to the outside through the opening 4 near the abutting portion 7' with the peripheral edge 8 of the opening 4.

On the other hand, the holding part 5 has a second fulcrum 10 protruding from the outer circumferential surface near the base of the jaw piece 6 and on the side facing the opening 4 on the outer circumferential surface.

<Function> In the present invention, which is provided with the above-mentioned means, the holder 1
A plate having an appropriate rigidity and length is inserted between the first fulcrum 9 and the second fulcrum 10 of the structure, and a force is applied to the first fulcrum 9 and the second fulcrum 10.
The holder 1 can be easily pushed into the receiver 2 .

Conversely, by inserting the plate piece between the first fulcrum 9 and the outer periphery of the opening 4 to widen the gap therebetween, the holder 1 can be easily taken out from the receiver 2.

<Examples> Examples of the present invention will be described below based on the drawings.

FIG. 1 shows an embodiment of the present invention. First, the present invention has an appropriate number of holders 1 that hold the ends of the signboard display sheet 11, and a receiver 2 that is formed separately from the holders 1 and receives each holder 1.

The receptor 2 is a long strip having a length corresponding to the end width of the signboard display sheet 11, and is a box having a hollow interior. This receptor 2 has an internal hollow portion 3 extending in its longitudinal direction on one side.
It has an opening 4 leading to.

The holder 1 has a holder 5 that holds the edge of the signboard display sheet, and a jaw piece 6 that protrudes outward from an appropriate position on the surface of the holder 5, and has the opening 4.
It is received into the receptor 2 by being inserted into the inner hollow portion 3 of the receptor 2. Each holder 1 is arranged inside the receiver 2 with an appropriate distance from other holders 1 adjacent to each other. An appropriate structure of the holding portion 5 of this holding body 1 will be described later.

The tip 7 of the jaw piece 6 comes into contact with the peripheral edge 8 of the opening 4 of the receptor inside the receptor 2, thereby holding the holding part 5 as a reverse hook so that it does not fall out from inside the receptor 2. It is something. As shown in FIG. 1, the jaw piece 6 protrudes from the side surface of the holding part 5, is curved or bent at an appropriate position, and extends toward the peripheral edge 8 of the opening 4.

Further, the tip 7 of the jaw piece 6 has a first fulcrum 9 that protrudes to the outside through the opening 4 near the contact portion 7' with the peripheral edge 8 of the opening 4.

As shown in FIG. 1, the tip of the jaw piece 6 is bent into an O-shape to form a tip 7, and a first fulcrum 9 is formed as the tip. but,
The embodiment is not limited to this embodiment, and as another example, the tip of the jaw piece 6 is formed into two branches, one of which is the tip 7, and the other is the first branch. It is also possible to implement it as a fulcrum 9.

On the other hand, the holding part 5 has a second fulcrum 10 protruding from the outer circumferential surface near the base of the jaw piece 6 and on the side facing the opening 4 on the outer circumferential surface.

Although the second fulcrum 10 shown in FIG. 1 has a curved surface in the part facing the opening 4 and a flat part in the opposite side, that is, the part facing downward in FIG. 1, the present invention is limited to this shape. It is also possible to implement it in other shapes.

driver. same as below. ) or another plate of suitable length and rigidity to connect the holder 1 to the receiver 2.
Push it inside.

At this time, place the tip of the screwdriver at the second fulcrum point 1.
0, and use the body of the driver to connect to the first fulcrum 9.
By pressing , the tip 7 of the jaw piece 6 can be easily pushed into the interior of the receptor 2.

The holder 1 can be removed from the receiver 2 by screwing the tip of a screwdriver between the first fulcrum 9 and the edge of the opening 4.

Here, an example of a tool most suitable for attaching and detaching the holding body 1 to the receptor 2 is shown in FIGS. 4 and 5, and a method of attaching and detaching the retainer 1 using this tool will be described later.

FIG. 4 shows a plan view of the tool, and FIG. 5 shows a front view thereof. The tool is formed entirely in an L-shape from a suitable material, and a scooping part 15 that is thicker than the other is provided at one end of the L-shape. This scooping part 15 has a concave part 16 at its tip that corresponds to the second fulcrum 10, and a first fulcrum 9 behind the scooping part 15.
and a corresponding reverse hook portion 17 (FIG. 5).

The other end 19 of the tool is tapered 19', 19' so as to be tapered like the driver. Although not shown, it is also effective to form the end portion 19 so that its thickness gradually decreases toward the tip.

FIG. 2 shows how the tool is used when attaching the holder 1 to the receiver 2. The scooping part 15 of the tool is inserted into the space formed between the outside of the holding part 5 of the holding body 1 and the jaw piece 6. At this time, the recess 16 of the tool corresponds to the second fulcrum 10. The reverse hook portion 17 of the other tool corresponds to the first fulcrum 9 (the reverse hook portion 17
enters the bottom of the first fulcrum 9). In this state, the tool holds the holder 1, and the holder 1 can be inserted into the receiver 2 through the opening 4 of the receiver 2. The holder 1 can be pushed into the receiver 2 by applying force to the tool while holding the holder 1.

At this time, a force is applied to the tool in the direction of arrow X in FIG. 2, using the second fulcrum 10 as a fulcrum, and applying force to the first fulcrum 9. By this action, the tip 7 of the jaw piece 6 enters into the inner peripheral edge 8 side of the opening 4.

Next, FIG. 3 shows how the tool is used to remove the holder 1 from the receiver 2 (in order to avoid complication of the drawing, the internal structure of the holder 5 is omitted). First, the end 19 of the tool is inserted between the first fulcrum 9 and the edge of the opening 4. When the tool is turned in the direction of arrow Y in this state, the tips of the jaws 6 are pushed out from the inside of the receptor 2, and the holder 1 is thereby taken out to the outside of the receptor 2.

A suitable example of the holding part 5 will be described below. As shown in FIG. 1, the holding portion 5 is formed into a hollow cylindrical shape. This holding part 5 has a substantially C-shaped cross section,
The end of the signboard display sheet 11 is inserted through the C-shaped notch. This holding part 5 has a cylindrical shaft 12 inside the hollow part. This shaft 12 is provided with an appropriate number of protrusions 12' on its surface. This axis 12
The end portion of the signboard display sheet 11 is wound around the surface of the signboard display sheet 11. In this way, the end portion of the signboard display sheet 11 is held between the inner wall of the holding portion 5 and the surface of the shaft 12. Holding part 5 is display sheet 1 for signboard
After holding the end of the holder 1, the holder 1 is inserted into the receiver 2, and by rotating the shaft 12, the tension applied to the signboard display sheet 11 can be adjusted. Of course, if such adjustment is not necessary and the end portion of the signboard display sheet 11 is simply held, it is also possible to use a holding section 5 having another configuration.

Further, it is effective to provide a structure that serves as a fulcrum when the holder 1 is taken out from the receiver 2. For example, the following configuration may be adopted. As shown in FIG. 1, this is a holding part 5 having a C-shaped cross section.
A tongue piece 13 is provided at one end of the notch, and a corresponding fulcrum 14 is formed at one end of the opening 4 of the receptor 2.

<Effects of the invention> It became possible to use an appropriate tool, and the attachment and detachment of the holder 1 to the receiver 2 became easy. Furthermore, even when a large load is applied to the end of the tool, it does not slip, and the above-mentioned removal work can be performed reliably.
