Description

[Detailed description of the invention] The present invention consists of a locking body in which a shaft rod having a knob is rotatably planted on the outer end thereof, and a locking plate having a window hole through which the knob can be inserted; A method for latching the lid of a school bag, etc., by sandwiching the tip side of the lid of the school bag, etc. between the clamping plate and a clamping plate formed with a bent part, and crimping the latching plate and the clamping plate to the tip side with rivets. Regarding equipment.

Conventionally, in the above device, the lid of a school bag or the like is made of a relatively flexible material such as leather, so when the hooking plate and the clamping plate are caulked with rivets, the caulked portion is pressed and the flesh is damaged. As the thickness becomes thinner, the clamping plate may tilt upward, creating a gap between the bent part and the hanging plate, especially the part where the initial sticker is attached to the surface of the clamping plate. If the area is caulked at the rear of the shank, the caulking position will be biased toward the rear, making the above gap even larger, which is not only unsightly, but also dangerous if fingers can get caught in the gap. Moreover, once it gets caught on an object, the clamping plate is forced to turn up, which causes the rivets to come off and the retaining plate to come off.

In this invention, a receiving hole is formed in the bent part of the clamping plate, and a locking piece is formed in the hanging plate, and by engaging these, there is a gap between the bent part and the hanging plate. This is to prevent any gaps from occurring.

The present invention will now be described in detail with reference to the illustrated embodiments.

1 is a locking body that is fixed to the main body of a school bag, etc.
A shaft rod with an elongated knob 3 at the outer end is rotatably installed in the center of a horizontally long rectangular case 2 made of non-magnetic metal, and a pair of permanent magnets ( (not shown) inside.

4 is a leather mounting plate provided at the free end of the lid plate of a school bag, etc., and has insertion holes 6, 6 for studs 5, 5 at the tip.
has been established.

7 is a leather piece that overlaps the mounting plate 4;
An insertion hole 8 corresponding to the insertion hole 6, 6 is provided at the front end.
8 is formed.

Reference numeral 9 designates a metal clamping plate that is substantially horizontally rectangular in plan view, and has a front bent portion 10 vertically formed on its front edge and having a height approximately equal to the combined thickness of the mounting plate 4 and the knob 7. , a receiving hole 11 is provided in the center of the front bent portion 10 , and 12 and 12 are the insertion holes 6 and 12 provided on the rear side of the holding plate 9 , respectively.
6, 8, and 8, and 13 is a rectangular depression formed on the front side of the holding plate 9 for attaching an initial sticker or the like.

Reference numeral 14 denotes a locking plate made of magnetic metal, which is substantially vertically rectangular in plan, has a knob 15 at the center of its front edge, and has two latches in its front half large enough to fit into the knob 3 of the locking body 1. The window holes 16 are arranged in parallel, and insertion holes 17, 17 corresponding to the above-mentioned insertion holes 6, 6 are provided on the rear side.

Reference numeral 18 denotes a locking piece that is formed protrudingly on the locking plate 14 and engages with the receiving hole 11. This locking piece is formed by making a U-shaped notch 19 in the rear part of the window hole 16, and cutting that part upward into a horizontal L shape. It is formed with a protrusion.

Reference numeral 20 denotes a fitting recess formed at the center of the front edge of the mounting plate 4, into which the locking piece 18 is fitted.

Then, the front end portion of the mounting plate 4 is overlapped with the rear side portion of the latching plate 14 by aligning the through holes 6 and 17 with each other, and the fitting recess 20 in the central portion of the front edge of the mounting plate 4 is locked. 18, and then overlap the knob 7 with the front end of the mounting plate 4 by aligning the insertion holes 6 and 8 with each other, and then insert the receiving hole 11 of the clamping plate 9 into the locking piece 18 at the rear thereof. while aligning the insertion holes 8 and 12 with the clamping plate 9.
The rivets 5, 5 are inserted into each of the above-mentioned insertion holes and crimped onto the latching plate 14.

In this way, the rear portion of the clamping plate 9 is attached to the studs 5, 5.
The front bent portion 10 is locked by fixing the locking piece 18 to the locking plate 14 and engaging the receiving hole 11, so even if it is caulked with the studs 5, the front will not rise. There is no gap between the lower end edge of the front bent portion 10 and the retaining plate 14 due to the inclination.

As is clear from the above, according to the present invention, the locking piece formed protruding from the rear part of the window hole of the hanging plate engages with the receiving hole opened at the center of the bent part of the holding plate. By doing so, the bent portion of the clamping plate is securely engaged with the latching plate, so that the clamping plate cannot be bent forward and upward by being caulked with rivets, as in the conventional case. There is no inconvenience caused by a gap between the part and the hanging plate 1, so there is no so-called rattling caused by the above-mentioned gap, and if clothes, etc. get caught in the gap, they will not turn up. This prevents the clamping plate and the locking plate from coming off the lid due to straining or excessive force being applied to the studs.

In addition, since the above-mentioned locking piece fits into the fitting recess formed in the center of the front edge of the mounting plate, the mounting plate, clamping plate, and hooking plate overlap in a stable manner, resulting in a safe and robust structure as a whole. It becomes a device.
