Abstract

Provided is an instantaneous-interruption prevention device and a telephone that can more effectively prevent instantaneous interruption of a call due to an impact. The instantaneous-interruption prevention device includes a latch part that operates so as to come into contact with a hook button of a telephone when receiving an impact, and the latch part stops motion of the hook button by coming into contact with the hook button.

First claim

The invention claimed is:

1. An instantaneous-interruption prevention device comprising a latch part that operates so as to come into contact with a hook button of a telephone when receiving an impact from a handset or from a push or a pull against a body or a housing of the telephone,
wherein the latch part stops motion of the hook button unless the hook button is in contact with the handset by fitting to the hook button to come into contact with the hook button in response to the impact from the handset being applied in a press direction of the hook button.

2. The instantaneous-interruption prevention device according to claim 1 ,
wherein the hook button is configured to swing about a first shaft, and
wherein the latch part stops motion of the hook button by fitting to the first shaft to come into contact with the first shaft.

3. The instantaneous-interruption prevention device according to claim 2 ,
wherein a reception part is provided to the first shaft, and

wherein the latch part stops motion of the hook button by fitting to the reception part.

4. The instantaneous-interruption prevention device according to claim 2 further comprising a pull spring that causes the latch part to be separated from the first shaft when not receiving the impact.

5. The instantaneous-interruption prevention device according to claim 2 , wherein the latch part is provided above the first shaft and is configured to swing about a second shaft when receiving the impact.

6. An instantaneous-interruption prevention device comprising a latch part that operates so as to come into contact with a hook button of a telephone when receiving an impact,
wherein the hook button has a button portion exposed outside the telephone and a hook lever extending from the button portion inside the telephone, and
wherein the latch part is provided under the hook lever and configured to swing about a second shaft when receiving the impact,
the instantaneous-interruption prevention device further comprising:

a weight part provided on an opposite side to the latch part with respect to the second shaft as a reference,
wherein a weight balance is set such that the weight part side is heavier than the latch part side with respect to the second shaft as a reference, and
wherein the latch part stops motion of the hook button by coming into contact with the hook lever.

7. A telephone comprising:
a hook button; and
the instantaneous-interruption prevention device according to claim 1 .

8. A telephone comprising:
a hook button; and
the instantaneous-interruption prevention device according to claim 6 .
