Description

[Detailed Description of the Invention] Industrial Application Field [0001] The present invention relates to a sheet metal joint metal used for mounting a wall panel or the like in the field of construction, for example.

Conventional technology Conventionally, an umbrella-shaped locking claw and a spring piece are provided around one shaft end of a shaft, and the shaft end is press-fitted into the locking hole with the locking claw to lock the locking claw into the locking hole. On the outlet side of the same and snap-engaged with the surface on the outlet side, the spring piece is elastically contacted with the surface on the inlet side to solidify and set, and similarly, the locking claw and the spring piece around the other shaft end. There is also known a connector in which a member to be mounted is mounted by press-fitting the member to be mounted into the locking claw through a locking hole to snap-fit the member to be mounted in the same manner as described above.

These are called clips and are integrally molded with synthetic resin.

Problems to be Solved by the Invention However, since the above-mentioned joining tool is one in which the locking claw and the spring piece are arranged side by side in the axial direction, the space between them becomes bulky, and if the length in the axial direction is inevitably long. Inevitably, therefore, there is a problem that an excessive space (dead space) is formed between the mounted member and the mating member that are joined together via the joining tool.

In addition, since the thickness of the shaft is limited and there is a limit to the strength of the locking claw and the spring piece, it is suitable for mounting lightweight parts, but it is sufficient for mounting relatively large and heavy members. There is a problem that the bonding strength cannot be obtained.

The present invention provides a sheet metal connector that can be manufactured thinly and inexpensively by sheet metal processing, does not require an excessive mounting height, can obtain a large snap engagement force, and can achieve firm mounting. .

Means for Solving the Problems As the above-mentioned means, the present invention provides a pair of claw plate portions snap-engaged with the locking holes of the mating member, a pair of spring plate portions that generate a tensioning action, and a member to be attached. The mounting seat plate portion for mounting is integrally formed by sheet metal working, the claw plate portion and the spring plate portion are bent from the mounting seat plate portion, and The above-mentioned joined metal product is formed by sheet metal working into a thin shape so that the claw plate portion is arranged therebetween. Further, as means for mounting the mounting seat plate portion on the mounted member, mounting holes for screwing or nailing are provided.

Action In the above-described sheet metal joining metal object, the attachment seat plate portion is screwed to the attached member, for example, through the attachment hole, and the attaching member is engaged with the mating member by the claw plate portion of the joining metal article. By press-fitting into the pawl, the pawl plate portion elastically restores on the outlet side of the locking hole and locks on the outlet side surface, and at the same time, the spring plate portion is elastically contacted with the inlet side surface of the locking hole and its reaction As a result, a tensioning action in the press-fitting direction is generated, and by the tensioning action, the mating member can be firmly captured between the claw plate portion and the spring plate portion. As a result, the member to be attached can be firmly attached to the mating member through the sheet metal joining metal member, and the attachment interval can be narrowed.

Embodiment An embodiment of the present invention will be described below with reference to FIGS. 1 to 6.

Reference numeral 1 indicates a sheet metal joint metal. The sheet metal joint metal 1 is formed by a claw plate portion 3, a spring plate portion 2 and a mounting seat plate portion 4.

The mounting seat plate portion 4 has a mounting hole 5 through which the sheet metal joint metal piece 1 is screwed to the mounted member A or the like. The claw plate portion 3 and the spring plate portion 2 are formed by bending from the edge of the sheet metal joint metal piece 1.

That is, each of the claw plate portions 3 is formed by bending so as to rise from the opposite edge of the mounting seat plate portion 4 so as to face each other, and the spring plate portions 2 are arranged with the claw plate portion 3 in between. It is formed by bending so as to stand up from the mounting seat plate portion 4 so as to face it, and punching and bending the whole metal plate.

The pawl plate portion 3 is press-fitted into the locking hole 6 of the mating member B and elastically restores at the outlet side of the locking hole 6 to snap-engage with the surface of the outlet side. 6 is elastically contacted with the inlet side surface of 6 to generate a tensioning action in the same direction as the press-fitting direction, to strongly capture the mating member B between the claw plate part 3 and the spring plate part 2, and the sheet metal joint metal 1 to the mating member. B locking hole 6
Firmly attached to. That is, the attached member A is firmly attached to the mating member B via the sheet metal joining metal piece 1.

In the first embodiment (see FIG. 1), the claw plate portions 3 are raised from the pair of opposed edges of the central portion of the mounting seat plate portion 4 in the inwardly forward direction, and the tips thereof are further outward. Claw piece 3 that doubles as a U-shape and doubles as a press-fitting guide piece across the width of the plate
a is formed, and the two pairs of spring plate portions 2 are arranged in the outward direction so as to be symmetrical with the claw plate portion 3 in between from the same edge of the mounting seat plate portion 4 in which the claw plate portion 3 is raised. Standing up while tilting backward, a pressing piece 3a extending across the width of the plate is formed at the tip.

FIG. 2 shows a developed view of the sheet metal joint metal 1 having the above-mentioned structure, that is, a punching form. As shown in the figure, two pairs of spring plate portions 2 and claw plate portions 3 are symmetrically arranged by using an effective material. It can be arranged properly.

Further, in the second embodiment (see FIG. 3), the mounting seat plate portion 4
The pair of claw plate portions 3 are raised from one of the facing edge portions of the mounting seat plate portion 4 so as to face each other in the forward tilted posture, and the pair of spring plate portions 2 are tilted in the backward tilted posture from the other facing edge portion of the mounting seat plate portion 4. It is launched facing each other.

Also in this embodiment, it is preferable that the claw plate portion 3 and the spring plate portion 2 are arranged symmetrically. Further, it is preferable that the mounting hole 5 is located between the opposing spring plate portions 2.

FIGS. 4 to 6 show a state in which the attached member A is attached to the mating member B by using the sheet metal joint metal 1 shown in the first embodiment. As described above, the sheet metal joint metal 1 is preliminarily screwed to the mounted member A side by the mounting hole 5 of the mounting seat plate portion 4, while the square locking hole 6 is directly formed on the mating member B. The attachment member having the engaging hole 6 is attached to the mating member B, and the attached member A is attached to the engaging hole 6 with the claw plate portion 3 of the sheet metal joining piece 1.
