Description

[Detailed Description of the Invention] This invention relates to the structure of a public telephone, and particularly to the structure of a safe of the public telephone that is built into the public telephone and stores call charge coins.

The basic structure of a public phone is that a safe is built into the bottom of the phone, and the coins inserted into the phone that cover the cost of the call are stored in a drawer-type safe that is inserted into the safe. The surplus coins, which are dropped and stored, and which exceed the cost of the call, pass through a predetermined return path and flow into a drop in a coin return slot attached to the front side of the vault.

However, in the structure of conventional public telephones, the coin return path and the safe are each made of unique members, which makes the structure at the bottom of the public telephone complicated, and as a result, the coin return passage and the safe are made of unique members. This was one of the factors that made it difficult to downsize and reduce costs.

The present invention was devised to solve the above-mentioned problems, and the purpose of the present invention is to provide a dedicated return coin that is installed at the top of the vault and that guides the returned coins to the drop in the return slot. To provide a structure of a public telephone in which the structure of the bottom of the telephone can be simplified by eliminating the funnel.

The present invention will be explained below based on the illustrated embodiments.

In the first embodiment, as shown in FIG. 1 and FIG. A rectangular opening 3a into which a drawer-type safe 4 is inserted is bored in the right side plate 3.

Furthermore, a storage slit S is opened near the rear of the upper plate 5 of the safe 2, into which storage coins, that is, coins for call charges, are guided.
Coins that fall through are stored in a safe 4 inserted in a safe 2.

Next, in the middle lower half of the front plate 6 of the vault 2,
A droplet 7 is provided opposite to which the returned coins, that is, coins exceeding the cost of the call, and defective coins flow in, but the portion of the front plate 6 above the droplet 7 is approximately U.
The recessed edge 6a is formed by cutting it off into a shape.

Therefore, the width line 5a in front of the slit S of the upper plate 5
A funnel-shaped recess 5b having a downward slope toward the drop 7 side is formed between the left and right high points of the upper plate 5 between the upper plate 5 and the recessed edge 6a.

The structure of this public telephone 1 is such that returned coins including defective coins returned by the upper mechanism of the public telephone 1 fall into the plane of the recess 5b.

When the vault 2 of the embodiment configured in this manner is used, the upper plate recess 5b of the vault 2 also serves as a guide for the lower end of the return path for the returned coins,
That is, since the returned coins that have fallen into the recess 5b are automatically guided to the dropper 7, there is no need to arrange a dedicated return funnel attached to conventional public telephones. is greatly simplified, and it is possible to reduce the size of the public telephone, especially in the height direction.

Next, a second embodiment shown in FIG. 3 will be described. The safe 8 according to the second embodiment is the same as the first embodiment described above except for the shape of the recess and the structure of the front plate. In this second embodiment, between the width line 9a of the upper plate 9 and the recessed edge 10a of the front plate 10, a recess 9b having a downward slope toward the front plate 10 is formed by press molding.
The width line 9b and the recessed edge 10a of the recessed portion 9b directly formed on the upper plate 9 by this press molding have the same width. A pair of guide plates 11 are formed facing each other on the left and right sides of the recessed edge 10a of the front plate 9, and the guide plates 11 have an inverted V-shape that is narrowed downward. has been done.

As described above, according to the structure of the public telephone according to the present invention, a concave portion having a downward slope is formed in the middle of the top plate of the safe on the return slot side. It becomes possible to greatly simplify the structure, thereby achieving miniaturization of the public telephone, particularly in the height direction, and cost reduction, which has the effect of increasing the practicality of the public telephone.

Claims (1)

[Scope of Claim for Utility Model Registration] A public telephone set with safes 2 and 8 consisting of a sealed box-shaped case in which a drawer-type safe 4 is inserted in the inner bottom of the outer case of the public telephone. In the structure, a storage slit S is provided at the rear of the safe top plate into which coins falling inside the public telephone are dropped.
A droplet 7 into which the returned coins flow is provided at the front of the front panel of the vault, and a droplet 7 is provided oppositely to the front of the front panel of the vault, and between the high points on the left and right sides of the upper panel from the middle part to the front edge of the upper panel of the vault. A structure of a public telephone set, characterized in that concave portions 5b and 9b having a downward slope are directly formed integrally with each other to receive a returned coin falling inside the telephone and guide it to the droplet 7.
