Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a stud receiver for a removable fastener used for doors of steel furniture and various types of OA equipment.

[Prior art and its problems]

As an example, a fastening fitting that can be opened and closed at the opening of a steel product and that can be quickly fastened is made up of a stud having a cam groove at the tip and a stud receiver that can be freely engaged and detached from the stud. Something was warm. However, it is relatively troublesome to attach such a stud holder to the edge of the opening, and the stud holder itself is made up of multiple components and is easily damaged at the joints, and the stud holder itself is relatively fragile. It had the disadvantage of being expensive.

[Purpose and structure of the invention]

Therefore, the object of the present invention is to provide a stud receiver which is formed by bending a single plate spring, and its structure is as follows.

That is, the present stud receiver is entirely made of a leaf spring, and has an engaging protrusion 3 in the stud insertion hole 4.
The engagement protrusion 3 removably engages with a spiral cam groove 2 formed at the tip of the stud 1.

Here, the features of this invention are as follows:
It is made of a plate spring base material having a substantially rectangular planar shape, and a substantially U-shaped cut 5 is provided along its two long sides and one short side. Thereby, the peripheral portion 6 and the center portion 7 of the base material are connected at the other short side.
Then, a peripheral portion 6 and a central portion 7 are provided for the connecting portion.
The stud insertion holes 4 and 8 are formed in the free end of the center part 7 and in the surface facing the free end of the center part 7, respectively.

[Example of idea]

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

FIG. 1 is a perspective view of the stud receiver of the present invention, FIG. 2 is a side view thereof, and FIG. 3 is a plan view thereof. Further, FIG. 4 is a partial vertical sectional view showing the state in which the present stud receiver is used. This stud receiver is the first
As is clear from the figure, a plate spring base material having a rectangular overall plane is used, and a substantially U-shaped cut 5 is formed therein. And the peripheral part 6 formed thereby
and the center portion 7 are folded back and bent in opposite directions relative to their connecting portions, and their opening sides face in the same direction. The folded shape of the peripheral portion 6 has a side surface approximately shaped like the cross section of a flask, and the folded shape of the center portion 7 has a substantially U-shape. And the center 7
Stud insertion holes 4 and 8 are formed in the free end and the surface opposite the free end, respectively. In addition, the hole edge of the stud insertion hole 4 is drawn to be convex upward in the figure, and a pair of engagement protrusions 3 are formed on the inner edge thereof.

In this stud receiver, the substrate 13 is elastically held between the lower upper surface of the peripheral portion 6 and the lower lower surface of the central portion 7, as shown in FIG. At the same time, the tip of the substrate 13 is brought into contact with the folded portion of the peripheral portion 6 to be positioned. Incidentally, a stud insertion hole 15 is pre-drilled in the substrate 13.
Next, the stud 1 that engages and disengages from this stud receiver is formed as shown in FIGS. 4 and 8. That is,
It has a head 9 at its rear end, and a cam groove 2 is formed at its tip. A locking shoulder 10 is formed at the base of the cam groove 2. At the same time, a retaining portion 11 is protruded from the cam groove 2 at a slight distance from the cam groove 2, as shown in FIG. As an example, this stud 1 is attached to a fastener 1 on a removable plate 14 of a door, board, etc., as shown in FIG.
Attached via 2. A screwdriver is fitted onto the head 9, and the head 9 is pressed and rotated 90 degrees to engage the stud receiver. Thus, the detachable plate 14 and the substrate 13 maintain a closed state. Also, detachable plate 1
4 can be opened in the reverse order.

Next, FIGS. 5 and 6 show other usage examples of this stud receiver, and in FIG. 5, the board 13 and the detachable plate 1
4 are mounted in close proximity to each other, and in FIG.
6 is provided. Further, FIG. 7 shows another usage example, and in this example, an L-shaped metal fitting 1 is attached to the board 13.
This stud receiver is attached via 7. Then, the board 1 is inserted through this L-shaped fitting 17.
3 and a detachable plate 14 are configured to be openable and closable.

[Effect of idea]

The stud receiver of the fastening metal fitting of the present invention has the above-mentioned structure and has the following effects.

(1) Since the peripheral part 6 and the central part 7 are folded in opposite directions with respect to their connecting part, the lower surface of the central part 7 and the peripheral part 6 in FIG.
The base plate 13 is inserted between the lower upper surface of the base plate 13 and the base plate 13 is elastically clamped, and the present stud receiver can be attached to the base plate 13 very easily. Furthermore, by abutting the tip of the substrate 13 against the folded portion of the peripheral portion 6, positioning of both becomes possible.

(2) Furthermore, the engaging protrusion 3 that engages with the cam groove 2 of the removable stud 1 is provided on a central portion 7 that is integrally formed with the peripheral portion 6, and the central portion 7 is folded and bent. Because of this, the engaging protrusion 3 itself can move elastically and be smoothly guided into the cam groove 2 of the stud 1. This makes engagement of the stud 1 extremely easy.

(3) Moreover, since the holding part of the board 13 and the engaging part of the stud 1 are formed of one piece, the stud holder has a small number of parts and is easy to handle, and it is easy to manufacture and can be provided at a low cost.
