JPS58117758A - Supporting device for handset of telephone set - Google Patents

Abstract

PURPOSE:To prevent a handset of a telephone set from being hooked off when an earthquake takes place, by detecting the happening of the earthquake and providing a means to support the handset by means of the detection. CONSTITUTION:When the earthquake takes place, a vibration weight 11 is vibrated. When a force of the vibration of the weight 11 exceeds a force of a spring 14, a coupling section 9 is turned in the direction of a P3 to release a latch of a support piece 5. Then, the piece 5 is turned with a spring 7 in the direction of a P4 to lock a handset R. In this case, a tip 19 of a lock spring 18 is slid in a guide groove 16 and inserted in a lock hole 17, then the piece 5 is blocked for the turning and locked to support the handset R.

Description

[Detailed Description of the Invention] The present invention relates to a device that holds a telephone receiver and prevents it from being disconnected when an earthquake occurs.When a large-scale earthquake occurs in a wide area, the problem is always that the telephone is disconnected. . The causes of telephone disconnections are relatively rare due to malfunctions in switching equipment, and are mainly due to telephone receivers being dropped in households, i.e., telephone receivers being dropped during an earthquake and remaining there. .

An object of the present invention is to provide a device that detects the occurrence of an earthquake and holds a telephone receiver in response to vibrations.

This will be explained below using figures.

Referring to FIGS. 1 and 2, telephone 1 (indicated by a broken line)
There is an opening on the back side.

The mounting portion 3 of the device 2 of the present invention is mounted in an opening provided on the back side of the telephone 1. However, the mounting portion 3
Other attachment means are also included.

A holding piece 5 is pivotally attached to a wall 4 erected on the mounting portion 3 by a shaft 6, and is rotatable.

An elastic body 7 is installed with one end fixed to the holding piece 5 and the other end fixed to the mounting part 3 (therefore, the holding piece 5 is biased in the direction of holding the handset. When in the non-holding position, that is, in the solid line position in the figure, the locking hook is stopped by the locking part 8 so as to maintain that position.
The locking part 8 has a curved engaging part 9 at one end, and a spring 1
It has a vibration-receiving type 11 held at the other end through a cylindrical shaft 11, and is pivotally mounted in the middle by a cylindrical shaft 12 so as to be swingable. The retaining portion 9 is provided to pass through an opening 13 provided in the holding piece 5, and the curved portion of the retaining portion 9 is held in the opening 13. The engaging portion 9 is biased in the direction of locking (arrow PI in the figure).The spring 10 and the vibration receiving weight 11 receive vibrations such as those caused by an earthquake, and resist the force P1 of the spring 14 to maintain the engagement. It provides the force required to connect and disconnect in 9 minutes.

A guide plate 15 is provided at the side end of the wall 4, and the guide groove 1
6 is formed in an arc shape. A lock hole 17 is provided at the lower end of the guide groove 16. A lock spring 18 is held by the holding piece 5 (see also FIG. 2), and the tip 19 is inserted into the guide groove 16 under pressure. The tip 19 of the lock spring 18 fits into the lock hole 17 when the holding piece 5 is in the position holding the receiver R (broken line in the figure), and the holding piece 5
lock.

A limit switch 20 is installed on the wall 4, and a holding piece 5
When the person holds the receiver R, it is turned on. The lamp 21 provided at the side end of the wall 4 is turned on when the limit switch 20 is turned on.
When this happens, the light is turned on by the battery 22.

The operation of the present invention constructed as above will be described below.In a normal state, the present invention is in the state shown in FIG.

Here, when an earthquake occurs, the receiving weight 11 vibrates.

When the force P2 due to the vibration of the vibration receiver 11 hits the force P1 of the spring 14, the retaining part 9 rotates in the direction P3, and the retaining piece 5
The retaining part releases the stop. Then, the holding piece 5 is rotated in the direction P4 by the spring 7, and holds the receiver R as shown by the broken line in the figure. At this time, the tip 19 of the lock spring 18
slides within the guide groove 16 and is fitted into the lock hole 17. Therefore, the holding piece 5 is prevented from rotating, and the handset R
is locked in the retained state.

The above embodiment is only one embodiment of the present invention, and the present invention may be modified without departing from the spirit thereof.
The present invention may include such modifications, and a buzzer may be provided on the lamp 21 of the present invention, or a buzzer may be provided in addition to the lamp 21. This buzzer, the occurrence of an earthquake, and the holding of the receiver can be detected without visual inspection.

Furthermore, by attaching a soft material K such as rubber to the front surface of the holding piece 5, it is possible to reduce the impact during the holding operation.The effects of the present invention are as follows. It is.

To securely hold a telephone receiver when an earthquake occurs and prevent the receiver from falling off due to vibration.

Since the handset can be locked in a held state, the handset will not come off even if it vibrates for a long time or the entire phone falls off the stand.

If the attachment part is inserted into the opening on the back side of the telephone and the telephone is attached, installation is easy and there is no need to make any changes to the telephone.

If you have a numbered lamp, it can also be used as a light when dialing in a dark place at night.

In addition to earthquakes, this also helps prevent the handset from falling off due to mischief by young children.
