Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a connecting fitting for attaching traffic signs, etc., which connects and secures the signs, etc., when attaching them to utility poles.

[Conventional technology]

Conventionally, when attaching signs etc. to telephone poles etc., the 7th
It was attached to a connecting metal fitting as shown in the figure.

That is, the sign B is wrapped around a cylindrical utility pole a, and the ears 10a and 10b formed at both ends of the sign B are screwed with bolts 11, etc., and the sign B is secured to the utility pole a. .

[Problem that the invention attempts to solve]

The conventional structure described above has a problem in that processing is required to form the protruding ears 10a, 10b at both ends of the marker B, resulting in high manufacturing costs.

Further, since the bolt 11 is connected and fixed to the ears 10a and 10b, the fastening method is complicated.

Furthermore, there was a problem in that it was difficult to freely attach and detach signs and the like due to corrosion of the bolts 11 and the like.

This invention was made to solve the above problems, and has a simple structure and an easy fastening method.
The object of the present invention is to provide a connecting fitting for attaching signs, etc., which is inexpensive to manufacture and has a strong fastening force that can be used even if it corrodes.

[Means for solving problems]

The present invention is a connecting fitting for attaching signs, etc., which connects both ends of signs, etc. made of metal plates, etc., which are attached by covering the entire circumference of utility poles, etc., and is made of two plastic plates, front and back, spaced parallel to each other. The central portions of the plates are connected by a connecting member, and a flat insertion groove with an opening at one end is provided on both sides of the connecting member into which the above-mentioned mark is inserted, and a metal claw is provided on the inner surface of the insertion groove to press the mark etc. when the plate material is plastically deformed. It is characterized by having the following.

The metal tab can have a shape that has a width in the axial direction of the telephone pole or the like and can hold the sign or the like through line contact.

Moreover, the metal fitting claws may be provided in a shape that protrudes alternately from the inside of the plate material and holds the sign etc. in a wavy shape.

〔Example〕

Hereinafter, the present invention will be explained based on embodiments shown in the drawings.

In FIG. 1, A is attached so as to cover the entire circumference of utility pole a. And the same sign A
Both ends are connected and secured by a connecting fitting 1 for attaching signs, etc.

The connecting fitting 1 for attaching signs, etc. is constructed as shown in FIG. 2. That is, 2a and 2b are plate materials that sandwich the sign A from both the front and back sides, and the connecting member 3 is connected to the center portion thereof. Then, the plate materials 2a, 2
openings 4a and 4b composed of b and connecting member 3;
Insert both ends of mark A into the plate material 2 from both front and back sides.
It is configured to be strongly held between a and 2b. A large number of metal claws 5, 5... are protruded from inside the plates 2a, 2b, and the metal claws 5 firmly hold the sign A from both sides of the sign A, thereby holding both ends of the sign A. It is designed to be connected and firmly fixed to utility pole a.

Here, by strongly pressing the sign A from both the front and back sides with the front and back plates 2a and 2b, the metal fitting claw 5
The sign A made of a metal plate or a resin plate is deformed into a wave shape, and the sign A can be reliably fixed with the metal claw 5. In Figure 3, sign A is board 2.
Metal fitting claws 5, 5 alternately protruding from the inside of a, 2b
... indicates a state in which it is plastically deformed into a wave shape and solidified.

FIG. 4 shows a connecting fitting 1 for attaching signs, etc., which has a structure in which fitting claws 5, 5, . In this case, both ends of sign A are not plastically deformed into a wave shape, but plate materials 2a and 2b
By firmly holding the sign A from both sides, it is possible to connect and secure both ends of the sign A.

In addition, if the shape of the metal fitting claw 5 is made to have a width in the axial direction of the utility pole a and to be in line contact with the sign A, the metal fitting claw 5
The frictional force between the mark A and the mark A can be increased, and the fastening can be made more secure.

In FIG. 5, reference numeral 5a denotes a metal claw having a width and a mountain-shaped cross section. Same metal fitting claw 5a
is in line contact with sign A over the entire width, and is designed to firmly secure sign A. In this case label A
When there is a protrusion on the protrusion t, the metal fitting pawl 5a is engaged with the protrusion t, and the fitting is more securely fastened. FIG. 6 shows an embodiment with another shape.

In the figure, a connecting member 7 is interposed between two plate materials 6a, 6b, and the connecting member 7 is interposed between two plate materials 6a, 6b.
It is configured to have an approximately N-shaped shape. Metal claws 5 are also provided on both sides of the connecting member 7 in a protruding manner.

The present invention is constructed as described above, in which the plates 2a and 2b made of plastic material sandwich the sign A from both the front and back sides, and the metal claws 5 protruding from the inside of the plates 2a and 2b strongly press the sign A. Therefore, mark A is firmly fixed. When the metal claws 5 are alternately protruded, the sign A is plastically deformed into a wave shape and securely fastened. Further, when the metal fitting claw 5a is formed into a shape having a width, the metal fitting claw 5a and the mark A are more strongly secured by line contact.

[Effect of idea]

As explained above, according to the present invention, the sign is strongly held between the plastic plate and the metal tabs protruding from the inside of the plate, and the sign is plastically deformed into a wave shape using the metal tabs that are alternately protruded. In addition, the metal claws are formed into a shape with a width so that the sign is in line contact with the sign, so the sign can be firmly fixed with a simple fastening method that only involves applying force to the board from both sides and plastically deforming it. can. Furthermore, since the structure is simple and no complicated processing is required, manufacturing costs can be reduced. Furthermore, it has the advantage that it can be used even after corrosion, unlike conventional screw structures.
