Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a coin removal prevention structure for a safe that is suitable for application to public telephones, vending machines, etc.

[Prior art] Conventionally, in public telephones, etc., in order to effectively utilize the volume of the safe, a lock for locking the safe was provided on the device housing side, and a locking piece was provided on the side wall plate of the safe when the lock was operated. The safe is locked by inserting it into the locking hole and engaging it. However, if one side wall of the safe is simply fixed with a locking piece, there is a risk that the other side may be pulled out from the safe storage portion of the device housing and tilted, and the stored coins may be extracted. Therefore,
As a structure to prevent such coins from being pulled out, the same applicant proposed a structure to prevent coins from being pulled out of the safe, as shown in Figures 3a, b, and c, in which the left and right side wall plates of the safe are fixed. Publication No. 58-171579). To roughly explain this in the same figure, 1 is the equipment housing of the telephone consisting of an upper housing 1A and a lower housing 1B, and 3 is a safe storage part 4 recessed in one side plate 2 of the lower housing 1B. A safe with an open top to be stored, 5 is a lock installed on the side plate 2 via a nut 6, and a locking piece 8 provided on a rotating shaft 7 of the lock 5 rotates when the lock is operated to open the safe. It is configured to be inserted into and engaged with a locking hole 9 recessed in one side wall plate 3A of the safe 3 through a longitudinally elongated slit-shaped long hole 10 provided in one side wall 4A of the storage section 4. . One side wall plate 3A of the safe 3 is inclined inward so that the distance between it and the other side wall plate 3B that faces it becomes narrower toward the rear end,
Therefore, the distance 20 between the side wall plate 3A and one side wall 4A of the safe storage section 4 is the minimum on the open end side of the storage section 4 when the safe 3 is completely stored.
The innermost side is the largest. On the other hand, the other side wall plate 3B
A locking claw 21 having an appropriate size and projecting laterally is integrally provided on the rear end 12 of the safe storage section 4.
A recessed fitting portion 22 into which the locking pawl 21 fits and engages is formed at the joint portion with the locking pawl 21 . In addition, 23 is a coin storage hole provided in the ceiling surface 25 of the safe storage section 4;
4 is a coin.

In such a configuration, the safe 3 is placed in the safe storage section 4.
When storing in the side wall plate 3 as shown in Figure 4.
Insert the safe 3 into the safe storage part 4 with the safe 3 tilted so that A and one side wall 4A are close to each other in parallel, and then insert the right side edge 3a of the front plate 3C of the safe 3 into the step part of the other side wall 4B. 11a. Then, by rotating the safe 3 clockwise using this contact portion as a rotation fulcrum p, the locking pawl 21 is fitted into and engaged with the recessed fitting portion 22, and at the same time, the left side edge 3b of the front plate 3C is moved to one side wall. 4A is brought into contact with the stepped portion 11b.
Then, the locking hole 9 and the elongated hole 10 correspond to each other, and when the lock 5 is locked, the tip of the locking piece 8 is inserted into the locking hole 9 through the elongated hole 10, thereby locking the safe 3.

[Problem that the invention attempts to solve]

However, even in a safe with such a configuration, although the safe 3 is locked at two points on the left and right, due to dimensional accuracy and manufacturing errors of the locking parts, the safe 3
If you pull it forcibly, it will tilt to the left or right, making it easy to pry open or damage the stored coins.
There was a problem of theft accidents occurring.

That is, when the safe 3 is tilted, a gap is created between the upper edge of the front plate 3C and the opening of the coin storage section 4.
If you insert a suitable tool such as a flat head screwdriver into this gap and use the side plate 2 of the device case 1 as a lever to distort the upper end of the front panel 3C, the gap will become larger and larger, and in this state, the device case 1 will be removed. When tilted toward the safe 3 side, the stored coins 24 in the safe 3 move along the inner surface of the front plate 3C, and can be extracted from the gap between the front plate 3C and the ceiling surface 25 of the safe storage section 4. It is something.

Therefore, as a method to solve such problems, the dimensional accuracy between the safe 3 and the safe storage part 4 is increased to reduce the gap, and the hole width of the locking hole 9 is made almost equal to the plate thickness of the locking piece 8. Alternatively, it is conceivable to make the thickness of the locking pawl 21 and the groove width of the recessed fitting part 22 approximately equal, or to increase the thickness of the front plate 3C to prevent deformation. A problem arises in that the cost increases significantly and becomes a major cause of cost increase.

Therefore, the present invention was devised in view of the above-mentioned conventional problems, and its purpose is to prevent coins from coming into close contact with the inner surface of the front panel of the safe, thereby making it possible to tilt the safe. To provide a coin extraction prevention structure for a safe that prevents stored coins from being extracted from the gap even if a gap is generated between a safe front plate and a ceiling surface of a safe storage part.

[Means to solve the problem]

In order to achieve the above object, the present invention stores a safe with a locking hole in one side wall plate in a safe storage part recessed in the side plate of the equipment housing, and is linked to the locking operation of the lock provided on the side plate of the equipment housing. In a safe in which the safe is locked by inserting a locking piece into the locking hole, one side wall plate of the safe is oriented in the direction of insertion of the safe with respect to the other side wall plate facing the opposite side wall plate. A locking pawl is provided at the rear end of the other side wall plate, and the locking pawl fits and engages when the safe is stored in the safe storage portion to prevent the safe from coming off. A recessed fitting portion is provided, a plurality of reinforcing and coin removal prevention ribs are protruded from the inner surface of the front plate of the safe, and a plurality of protruding members are protruded from the ceiling surface of the safe storage portion in correspondence with the ribs. The ribs are arranged in parallel in a direction perpendicular to the insertion direction of the safe at intervals smaller than the outer diameter dimension of the smallest diameter coin stored in the safe, and the protruding member is arranged between adjacent ribs and between the ribs and the side wall of the safe. It is inserted between the plate and the plate.

[Effect]

In this invention, a plurality of ribs are protruded from the inside surface of the front panel of the safe at intervals smaller than the outside diameter of the smallest coin, so there is a gap between the front panel of the safe and the ceiling of the safe storage compartment. Since the ribs are in the way, it is impossible to remove the stored coins along the inner surface of the front plate, and the protruding member prevents foreign objects such as paper from being inserted.

[Example] Hereinafter, the present invention will be described in detail based on an example shown in the drawings.

FIG. 1 is a cross-sectional view showing an embodiment of a coin removal prevention structure for a safe according to the present invention, and FIG. 2 is a cross-sectional view taken along the line shown in FIG. 1. Components and parts that are the same as those in FIGS. 3 and 4 are designated by the same reference numerals, and their explanations will be omitted. In the following figures, this embodiment has a plurality of reinforcing and coin removal prevention ribs 30 on the inner surface of the front plate 3C of the safe 3 in a direction perpendicular to the insertion direction of the safe, which is smaller than the outer diameter dimension D of the smallest coin 24. Ribs 3 protruding at intervals and adjacent to the ceiling surface 25 of the safe storage section 4
Between 0 and the rib 30 and the side wall plates 3A and 3B of the safe 3
The present invention is characterized in that a plurality of protruding members 31 are vertically inserted between the two, and the other structure is the same as the conventional structure shown in FIG. The protruding member 31 is provided near the opening of the safe storage section 4.

Note that 32 is the bottom plate of the lower housing 1B, and 33 is a rubber foot.

Thus, in the coin removal prevention structure of the safe constructed as described above, the front plate 3C of the safe 3 is reinforced by the ribs 30 integrally protruding from the inner surface thereof, so that the safe 3 cannot be forcibly pulled. Even if you try to deform the front plate 3C by tilting it as shown in FIG. 1 to create a gap between the front plate 3C and the ceiling surface 25 and inserting a screwdriver or the like through this gap, the ribs 30 prevent the front plate 3C from being deformed. Therefore, the gap does not become large, and even if a large gap occurs, the spacing between the ribs 30 and the spacing between the ribs 30 and the side wall plates 3A, 3B are set smaller than the outer diameter dimension D of the minimum coin 24. Therefore, even if the phone case is tilted toward the safe 3 side, the coins 24 will not touch the front panel 3.
does not come into close contact with the inner surface of C, therefore, the front plate 3C
The coin 24 will not be pulled out from the gap between the coin 24 and the ceiling surface 25, and theft accidents can be prevented.

Moreover, high dimensional accuracy is not required for the safe 3, the safe storage part 4, the locking hole 9, the locking claw 21, the recessed fitting part 22, etc., and manufacturing is easy.

Furthermore, the protruding member 31 is connected to the front plate 3C and the ceiling surface 2.
This prevents paper or the like from being inserted through the gap between the If the coin storage opening 23 is blocked by inserting a strong thin plate such as an underlay, the coin 24
It is said to be effective in preventing unauthorized use, malfunction, etc.

[Effect of idea]

As explained above, the coin removal prevention structure of the safe according to the present invention is such that the front plate of the safe is reinforced with a plurality of ribs, so it does not deform, and the spacing between the ribs is adjusted to the minimum diameter of the stored coins. Since it is set smaller, even if a gap occurs between the front panel and the ceiling surface of the safe storage section, the stored coins will not be removed. This prevents paper or the like from being inserted through the gap. Furthermore, it does not require high dimensional accuracy and can be manufactured at low cost, which has great practical effects.
