Description

[Detailed Description of the Invention] The present invention relates to an improvement of a fastener for relatively small cases with lids.

Conventionally, this type of fastener has a rectangular frame that is separately press-worked and caulked to the main plate in order to attach a stop ring to a silver stopper that is fixed to the lid to the main plate that is fixed to the main body.

Therefore, there are drawbacks such as requiring time and effort for punching with a die and assembling operations, reducing work efficiency and increasing costs.

The purpose of the present invention is to provide a fastener that is easier to manufacture than conventional fasteners of this type, is suitable for mass production, and can be manufactured at low cost.

In order to satisfy the above object, the present invention is constructed as follows.

That is, the present invention includes a locking silver 1 that is fixed to a lid frame hinged to a case body a, and a fastener main body 2 that is attached to the case body a.
A fastener for cases, in which a retaining ring 4 to which a retaining protrusion 3 protruding from a retaining silver 1 engages is rotatably attached to a retainer main body 2, and a spring 5 is applied to the retainer ring 4. , the center part of the main body 2 of the fastener is bent into a portal shape to form a mounting frame 6 for the stop ring 4, and insertion holes 7a and 7b for the stop ring 4 are formed in both left and right sides 6a and 6b. The left and right tips 4a and 4b to be inserted into the insertion holes 7a and 7b of the retaining ring 4 are formed into an L shape, and a notch 8 is provided between the double-ended light ends 4a and 4b. The L-shaped light end 4a has a cutout 9 to narrow the width of the corner, and the left and right sides 6 of the mounting frame 6 are fitted with curved leaf springs 10 loaded on the back side of the mounting frame 6 and fixed at both ends.
The retaining ring 4 is made by making two cuts 11 parallel to a and 6b.
An intermediate piece 12 that matches the notch 8 of
This is a fastener for small cases that is provided with curved pressing pieces 13, 13'.

Since the present invention has the configuration described above, it is not necessary to caulk the rectangular frame to the main plate as in the conventional case, and it can be assembled very easily.

Also, since the stop ring has a cutout 9 on one side of the left and right light ends 4a, insert the cutout 8 between the two light ends into one side of the portal mounting frame, and The L-shaped light end 4a is inserted into the insertion hole 7a.
The other L-shaped light end 4b is rotated over the mounting frame 6 using the cutout 9, guided to the other side, and inserted into the insertion hole. By loading the curved leaf spring 10, the notch is regulated by the intermediate piece 12 of the leaf spring, and there is no risk of it shifting left or right and coming off.

Furthermore, the left and right curved spring pieces 13, 13' of the intermediate piece have the characteristic that they can provide a sufficient spring action to the L-shaped light ends 4a, 4b, and can also achieve the locking effect without any problem.
