Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention mainly relates to a fastening fitting that can quickly attach and detach a panel to a frame or the like.

[Prior art and its problems]

For example, in order to attach the front decorative plate of a pachinko game machine to its support frame, it has conventionally been common to use screws. This front decorative board is something that can be replaced with a new one at a certain period of time, but since a large number of such game machines are arranged in one store, it takes a lot of time to replace all the front decorative boards. It required a lot of effort. And, to that extent, the efficient operation of the store was hindered. In addition to fastening methods using bolts and nuts, there were also fastening fittings with spiral cam grooves, but these female fittings were made up of multiple parts and had the disadvantage that assembly and attachment to frames, etc. were troublesome. had. In addition, a tool such as a screwdriver is required to engage and disengage the male fitting, which is relatively troublesome.

[Purpose and structure of the invention]

Therefore, the present invention is designed to allow various plates to be screwed onto frames etc. with just one touch, without requiring any tools such as a screwdriver, by screwing with fingers, and in particular, the female metal fittings are constructed integrally with one piece of material. The purpose is to provide

The fastening fitting of the present invention has the following configuration.

That is, the head 1 is provided at the rear end of the shaft of the male metal fitting 4 and is large enough to be screwed around with fingers. At the same time, a cam groove 2 is formed in a spiral shape at the tip of the shaft, and a locking shoulder 3 is formed at the rear end of the cam groove 2. moreover,
The female metal fitting 10 is entirely constituted by a plate spring formed into a substantially U-shape, and insertion holes 7 and 8 are provided in both opposing sides 5 and 6 of the female metal fitting 10. At the same time, one of the side surfaces 5
A pair of protrusions 9 are formed on the edge of the insertion hole 7 , and the protrusions 9 are guided by the cam groove 2 and engaged with the locking shoulder 3 . Further, the other side surface 6 is configured to be fixed to the mounting member 13.

[Example of idea]

Next, one embodiment of the present invention will be described based on the drawings.

FIG. 1 is a perspective view of the male metal fitting 4 and female metal fitting 10 of the present fastening metal fitting, and FIG. 2 is a side view showing the tip portion of the male metal fitting 4.

First, the male metal fitting 4 of the present invention has a synthetic resin head 1 fixed to the rear end of a metal shaft. The head 1 is formed in a size such that the outer periphery can be easily twisted by pinching the outer periphery with fingers, and a large number of grooves for preventing slipping are formed on the outer periphery. A cam groove 2 is threaded on the tip of the shaft of the male fitting 4, and a locking shoulder 3 is provided at the rear end of the cam groove 2. Further, a retaining portion 11 is provided adjacent to the rear end of the cam groove 2.
is formed in a protruding ring shape as shown in FIG.
Next, the female metal fitting 10 is made by cutting the plate spring material into a cross shape, and inserting holes 7, 8 and holes 16 into each part of the plate spring material.
and a pair of protrusions 9 on the inner peripheral edge of the insertion hole 7.
form. Then, the piece having the insertion hole 7 is
The U-shaped portion 17 is formed by bending it into a letter shape and bending the piece without a hole. And, these are configured integrally. The projection 9 described above is formed so that it can be fitted into the cam groove 2 of the male metal fitting 4 almost with one touch.

[Effect of invention]

Next, an example of how to use this fastening metal fitting will be explained.

First, holes (not shown) are bored in the mounting member 13 constituting the frame or the like at positions that align with the insertion holes 8 and 16 of the female metal fitting 10. Then, attach the side surface 5 from the back side of the attachment member 13 such as a frame,
The female metal fitting 10 is fixed to the mounting member 13 using rivets, screws, or the like (not shown) in the hole 16. Next, a hole slightly larger than the shaft portion of the male fitting 4 is previously drilled in a panel 14 such as a front decorative plate for a pachinko game machine. Then, the shaft portion of the male metal fitting 4 is inserted into a hole (not shown) in the panel 14. Then,
A fastener 12 is press-fitted from the tip of the shaft part of the male fitting 4, and is held on the rear end side of the retaining part 11. To fix the panel 14 to the mounting member 13, hold the outer periphery of the head 1 with your fingers and tighten the male fittings 4.
Insert the shaft portion into the insertion hole 8 and the insertion hole 7. Then, when the head 1 is rotated to the right, the protrusion 9 is locked to the locking shoulder 3 of the male fitting 4 almost with one touch. Thereby, the panel 14 can be attached to the mounting member 13.
can be held securely. In addition, female metal fitting 1
The U-shaped portion 17 at 0 prevents abnormal deformation of the side surface 5. Next, attach the panel 14 to the mounting member 1
3, by screwing the head 1 of the male metal fitting 4 in the left direction, it can be removed almost with one touch without requiring any fastening tools. Therefore, by locking a new panel 14, into which the male fitting 4 has been inserted in advance, to the mounting member 13 in the same manner as described above, the panel can be quickly replaced.

[Effect of idea]

The present invention has the above configuration and has the following effects.

(1) The female metal fitting 10 of this fastening metal fitting is entirely composed of a U-shaped plate spring, and is integrally constructed so that the side surface 6 of the plate spring is fixed to the mounting member 13. The attachment is easy, the number of parts is reduced, and the fastener can be provided at low cost.

(2) Moreover, the male fitting 4 is formed to a size that allows the head 1 to be rotated with a finger, and the female fitting 10 has an insertion hole on one side 5 of the U-shaped leaf spring. 7 is drilled and a pair of protrusions 9 are provided on the edge of the hole, so that the side surface 5 is easily elastically deformed and the protrusions 9 are smoothly engaged with the locking shoulders 3 of the male fitting 4. , the metal fittings can be fastened with just one touch.
