Description

[Detailed Description of the Invention] The present invention relates to a latch mechanism used when closing an opening/closing body.

For example, a public telephone has a safe that stores the coins put into it, and the money in the safe is collected at regular intervals or when the safe is full and exchanged for a new safe. However, it is also necessary to lock the many recovered safes in one place and take out the accumulated coins 4.

Therefore, this type of safe is easy to carry and is simply constructed of a housing with one side open so that coins can be easily taken out from inside and a lid that covers the coins.

For this reason, in such safes, it is necessary to use the sound of the locking mechanism to securely connect the metal to the housing and lid for security reasons, but in this case, the safe is housed inside the phone housing. Therefore, it is not necessary to use a complex structure as a locking mechanism, and it is also undesirable in terms of cost.

Therefore, conventionally, in this type of safe, in order to connect the case and the lid, the lower side edge portions are connected by a hinge, and on the other hand, the hook is made of metal and the catch is made of metal. It was common to have a structure in which they were connected using a gold film or a gold lock.

However, in such a structure, the hook of the hook and stop mechanism is rotatably attached to the casing, and the hook is attached to the metal locking mechanism, and the metal receiver is attached to the metal locking piece so that the hook can be rotated. Because of this, the usual hooks that connect the metal main body and the mounting piece to the casing with a metal hinge or a hinge sound are not suitable for security reasons.

In other words, if the above-mentioned hook is made of metal, if it is fixed to the surface of the casing by screwing or welding the mounting frame metal, the screws, hinges, hinge pins, etc. will be exposed on the outside of the casing, and the mounting piece will be exposed. Even if the chisel was fixed inside the metal casing, the hinge or pin of the hinge would be exposed to the outside, making it difficult to have a security effect.

A case having a screw-fastened structure as described above has disadvantages in that the installation work is troublesome and the case is unfavorable in terms of cost.

Therefore, conventionally, in this type of hook and stop mechanism, the hook has a mounting frame bent on the side edge of the metal so that the metal can be safely attached to the housing. Insert the metal cover of the mounting piece into the long groove that has been drilled, and fix a screw, etc., to the tip of this mounting piece.This prevents the screw from hitting the inner wall of the case, and prevents the metal from being removed or removed during the process. However, in such a case, the work of attaching the hook is troublesome, and the number of parts is large, resulting in high cost.

In view of these points, the present invention has been designed to simplify the installation process by making the hook simpler than the gold plate, and to ensure safe installation by preventing the metal from being removed. The present invention will be explained in detail below using the examples shown in the drawings.

Fig. 1 shows an example of a case where the safe is housed in a metal public telephone set according to the present invention. 1 and a lid 2 attached to the rear of the opening of the casing 1 so that it can be opened and closed by a hinge (not shown), and a hooking mechanism is provided at the front joint of the casing 1 and the lid 2. As for a pair of gold pears, gold 3 is attached to the hook and gold 4 is attached to the receiver.
These hooks are made of metal, and the receiver is made of metal 4.
The lid body 2 and the gold plate lock 5 are connected using gold.

In this case, it goes without saying that the hinge connecting the housing 1, the lid 2, and the metal behind the metal box should be installed inside the safe for safety reasons. A lever 6 for extracting sound is provided, and a hole T for storing coins is bored in the upper part of the lid body 2.

Now, according to the present invention, the hook in the hook and stop mechanism is
This is the characteristic part, and the related part 4 will be explained in detail below in FIG. 2 and FIG. 3.

That is, the hook 3 is formed by bending a metal plate thicker than the thickness of the housing 1 and the lid 2, and the receiver has a vertical locking groove 8 corresponding to the hook 4 drilled in the center of the metal. The main body part 9 has a substantially triangular shape, and mounting pieces 10 and 4 are bent diagonally from the lower edge of the main body part 9, and a rectangular groove 11 is bored in the center of the mounting piece 10. .

The main body part 9 is bent into a mounting piece 10 mm below the locking groove 8, and a knob 12 is bent at the upper end of the main body part 9 on the opposite side of the mounting piece.

In addition, both sides of the lower edge of the main body part 9 have notches, and the notches 1
3 serves as a stopper for the housing 1 of the main body portion 9.

On the other hand, the hook is attached to the side wall 1a of the casing 1, which is made of 3-metal metal.
The hook is formed with a gap slightly larger than the plate thickness of the metal plate 3, and the hook is a long structure 15 having a length 4 which is approximately the same width as the mounting piece 10 of the metal plate 3.
is formed, and in this long groove 15, the hook is a mounting piece 1 of the metal 3.
It is configured to be installed by inserting it.

At the upper edge of this long groove 15, an engaging piece 16 corresponding to the rectangular groove 11 of the mounting piece 10 is cut and raised diagonally downward inside the housing 1. The length is set approximately equal to the gap between the long grooves 15.

Therefore, this engagement piece 16 is designed to close the long groove 15 from above at a position corresponding to the short groove 11.
5, the mounting piece 10 is pressed to a large extent and the engagement piece 16 is elastically deformed.
By further inserting the mounting piece 10k gold into the rectangular groove 1
The engaging piece 16 is fitted into the inner part 1, and the hook 34
Configured for installation.

The receiver has a tongue-shaped locking piece 18 that is fitted into the locking groove 8 of the metal 4 and the locking piece 3, and the pin of the padlock 5 is located in the center of the locking piece 18. A lock hole 19 into which the lock is inserted is bored.

This receiver is fixed at a position where the locking piece 18 is inserted into the locking groove 8 when the hook 4 is rotated by the side wall of the lid body 2.

In this case, the receiver may be welded to the gold 4 metal lid body 2, but the hook is the metal 34. When the hook is stopped, the receiver is on the front side of the metal 4.
Since the main body portion 9 of the receiver is covered, the receiver can also be screwed to the flange metal lid body 2 of the metal 4.

In the hook and stop mechanism configured in this way, as shown in Fig. 2, the hook is completely fixed by simply press-fitting the fitting piece 10 of the metal 3 into the groove 15 from the front side of the metal housing 1. 3. It can be easily attached to the housing 1.

That is, when the tip of the attachment piece 10 hits the engagement piece 16, the engagement piece 16 is elastically deformed.

Then, when the mounting piece 10 is further inserted and twisted so that the engagement piece 16 faces the rectangular groove 11, the engagement piece 16 is fitted into the rectangular groove 11 due to its elastic force, and the hook 3 is thereby attached. The work is completed.

(See Figure 4) The hook 3 installed in this way is
As shown in FIGS. 3 and 4, when the receiver is not hooked onto the catch 4, the tip side edge of the rectangular groove 11 of the mounting piece 10 and the tip of the engagement piece 16 engage, and the housing is closed. Withdrawals from 1 are prevented from being withdrawn.

Also, when removing the hook 3 from the receiver 4, attach the mounting piece 1.
0.Holding can be easily done by rotating all 3 metals while gradually pushing it into the inside of the housing 1 from the long groove 15 of the metal 15.Furthermore, when the metal 3 is fully opened, the locking can be done as shown in Fig. 3 (dotted chain line).
And as shown in FIG.
The transfer money can be regulated while in contact with a.

Therefore, in such a hook 3, the engagement piece 16 of the housing 1 is always fitted into the rectangular groove 11, and the hook engages with the edge of the rectangular groove 11 by the rotating movement of the hook 30. In addition, in the above-mentioned embodiment, when the latch mechanism according to the present invention is applied to a safe housed in a metal public telephone, the movement of money in the withdrawal direction is definitely regulated. However, it is not limited to this, and any opening/closing body consisting of a casing and a lid or a door may be used. effective.

In addition, the hook and the catch of the hook and stop mechanism are attached to the case 1 and the lid body 2, respectively, but the present invention is not limited to this, and they may be attached in the opposite direction. The shape can also be changed as appropriate.

In short, the hook of the opening/closing body can be fitted with a long groove in the part where it is attached, and the hook can be engaged with the rectangular groove of the metal by cutting and raising the long groove inward from the edge of the long groove.

As explained above, in the hook and stop mechanism according to the present invention, the hook is formed with a rectangular groove on the metal mounting piece, and this mounting piece is inserted into the metal mounting piece.
Since the engaging piece is cut and raised from the edge of the long groove of the opening/closing body and engaged with the rectangular groove of the engaging frame, the structure is simple and the hook can prevent the metal from being removed. Moreover, the mounting of the hook can be easily done using the elastically deformed metal of the purple engagement piece, which improves productivity and reduces the deposit by one part, significantly reducing the manufacturing cost. It has excellent practical effects such as being able to reduce the amount of water used.

In the hook and stop mechanism of the present invention, the hook can be held rotatably by the engagement between the engaging piece provided inside the full-tone opening/closing body and the rectangular groove, so it can be held in a rotatable manner, such as on a safe. It is particularly useful when used in problematic closures.
