Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a telephone that can be used as a tabletop type or a wall-mounted type.

[Conventional technology]

Telephones are broadly classified into tabletop types, which are used by being placed on a stand, etc., and wall-mounted types, which are used by being suspended from a wall surface. Since the desk phone has a structure in which the handset is placed on the main body, a structure for holding the handset is not particularly required. On the other hand, in a wall-mounted telephone, the main body is fixed to the wall via a mounting bracket, but some kind of structure for holding the handset attached thereto is essential. For example, the phone itself has
A wedge-shaped protrusion is integrally provided on the wall of the earpiece insertion recess, and the handset is provided with a recess on the peripheral wall of the earpiece, so that when the handset is assembled to the telephone main body, the protrusion and the recess are connected to each other. The engagement prevents the handset from falling off. By the way, it would be convenient for the user if both the tabletop type and the wall-mounted type could be used, and it would also be advantageous in terms of manufacturing since the phone main body could have a unified specification.

[Problem that the invention attempts to solve]

However, if the above-described handset holding structure is directly applied to a tabletop type device, the handset may get caught when picked up, making it difficult to use. In addition, when a user tries to pick up the handset in a hurry when receiving a call, it gets caught and dropped, causing the call to be disconnected and causing trouble to the other party, which is a practical problem.

Therefore, as a method to solve such problems, for example, a recess is provided in the peripheral wall of the handset earpiece, a mounting hole is provided in the phone body that communicates from the bottom surface with the fitting recess of the handset earpiece, and this mounting hole is connected to the wall surface. The desk top is adapted to suspend and support the telephone main body on the mounting bracket by fitting the hooks of the mounting bracket fixed to the table, and to hold the handset by projecting and exposing the tips of the hooks into the fitting recesses. , a telephone that can be hung on the wall has been proposed (Japanese Patent Laid-Open No. 59-262820).

In this configuration, when used as a desk phone, there is no need for a mounting bracket, which has the advantage of solving the above-mentioned problem. Since the telephone body needs to be formed by a peripheral wall, the structure of the telephone main body becomes complicated and the cost of manufacturing the mold becomes extremely high, which is a major obstacle to cost reduction. In addition, when the mounting hole is used as a tabletop type, since it is open, the inside of the phone can be seen, which not only has an unfavorable appearance, but also obstructs the installation of other parts and reduces mounting efficiency. Ta.

[Means for solving problems]

The desk-top and wall-mounted telephone according to the present invention was developed to solve the above-mentioned problems, and includes a rotary lever inside the telephone body with its tip protruding from the back side of the telephone body. A handset locking protrusion that can freely move in and out of the handset earpiece fitting recess provided on the telephone body is provided on the rotating lever, and a spring causes the lever to rotate in a direction in which the protrusion exits from the fitting recess. The rotary lever is rotated by a mounting bracket when hanging on a wall, so that the protrusion protrudes into the fitting recess.

[Effect]

In the present invention, when the phone is hung on a wall, the handset locking protrusion protrudes and is exposed into the handset earpiece fitting recess to hold the handset, and when the phone is placed on a table, it is housed within the telephone body and closes the fitting recess.
