Abstract

PURPOSE:To easily detach a handset by forming the tip part of a movable engagement pawl in such a way that an outside inclination surface and an inside inclination surface become acute with respect to the rising and setting direction of the movable engagement pawl. CONSTITUTION:When a receiving part 13 in the handset 11 is detached from a recessed part 20 in a handset pedestal 12, force for detaching the receiving part 13 in the handset 11 operates on the tip inclination surface 33 of the movable engagement pawl 23 from the receiving part 13. With the force, the engagement pawl 23 is shifted to a setting direction, whereby partial force is generated. Consequently, the engagement pawl 23 is set in the pedestal 12 against the force of a spring 29, whereby the pawl 23 is detached from the engagement hole 16 of the handset 11. By operating force for detaching the handset 11 with respect to the outside inclination surface 32 and the inside inclination surface 33, the engagement pawl 23 can be set into the inner direction of the pedestal 12 against spring force. Consequently, the handset 11 can easily be detached only with adding force for detaching the handset 11.

[Industrial application field]

The present invention relates to a telephone equipped with a handset and a handset cradle, and more particularly, the present invention relates to a telephone set having a locking hole, a handset cradle having a recess for receiving the handset, and a handset and a handset cradle. This invention relates to an improvement in a handset holding mechanism for a telephone set, which includes a spring-biased movable locking pawl for fixing the handset in a recess in a handset cradle by engagement with a locking hole.

Telephones equipped with a handset and a handset cradle, especially car phones and portable wireless telephones that are susceptible to vibrations and shocks from the outside, can be A holding mechanism is required to stably fix the handset to the handset cradle. On the other hand, when a handset holding mechanism is incorporated into the handset cradle of a telephone, when the handset is attached to and detached from the handset cradle, the handset holding mechanism has a release action to enable the handset to be attached and detached. need to be done. If a separate external operation is required to release the handset holding mechanism when attaching and detaching the handset, attaching and detaching the handset becomes troublesome. Further, since an operating mechanism is required to release the handset holding mechanism, the structure becomes complicated.

Therefore, the handset can be easily attached and detached without requiring an independent external operation to release the handset holding mechanism, and moreover, the handset can be stably fixed when attached to the handset cradle. It would be desirable to have a telephone with a simple handset holding mechanism that can be used to hold the handset.

(Prior art and its problems) Figures 7 to 1O show the handset holding mechanism of a conventional car telephone.Referring to these figures, the conventional telephone has a handset 1 and a handset. The handset cradle 2 has a receiver part 1a of the handset 1.
A recess 2a is formed to receive the handset holder 2.
The recess 2a is provided with a protrusion 3 that can be engaged with a recess 1b provided at one end of the receiver 1a of the handset 1. A movable locking claw 4 facing the projection 3 is provided in an opening formed in the wall surface of the recess 2a facing the projection 3 so as to be retractable, and a movable locking claw 4 is provided in the receiving portion 1a of the handset l. A locking hole IC that can be engaged with 4 is formed.

As shown in FIGS. 9 and 10, in the conventional telephone, a cam plate 5 is attached to the rear end of the movable locking pawl 4, and the movable locking pawl 4 is connected to the cam plate 5 and the handset receiver. It is urged in the direction of protrusion into the recess 2a by the force of a compression spring 6 provided between it and the rear wall of the stand 2. The plate-shaped movable locking claw 4 has an outer surface 4a located on the opening side of the recess 2a and an inner surface 4b located on the bottom side of the recess 2a. 4a is inclined toward the tip of the movable locking pawl 4 so as to form an acute angle with respect to the direction of protrusion and retraction of the movable locking pawl 4.

Therefore, in the conventional telephone, when the receiver 1a of the handset 1 is inserted into the recess 2a of the receiver holder 2, the receiver 1a of the handset 1 is inserted into the outer surface 4a of the tip of the movable locking claw 4. When pressed, the movable locking pawl 4 sinks into the handset holder 2 against the force of the spring 6 due to the force in the protruding/retracting direction of the pressing force. When the receiver 1a of the handset 1 fits into the recess 2a of the handset holder 2, the movable locking pawl 4 is pushed by the spring 6 and fits into the locking hole 1c of the handset 1. , the handset 1 is fixed in the recess 2a of the handset cradle 2.

However, in conventional telephones, since the inner surface 4b of the movable locking pawl 4a extends parallel to the direction in which the movable locking pawl 4 protrudes and retracts, when attempting to remove the handset l from the handset holder 2, With that force, the movable locking pawl 4 cannot be recessed into the handset holder 2. Therefore, in the handset holder 2 of the conventional telephone, the movable locking pawl 4 acts on the inclined surface 5a of the cam plate 5. A release operation button 7 is provided for retracting the locking pawl 4 into the handset holder 2 against the force of the spring 6. Therefore, when removing the handset 1 from the recess 2a of the handset holder 2, press the release operation button 7 to disengage the movable locking claw 4 from the locking hole IC of the handset l.
It was necessary to remove the handset 1 from the recess 2a of the handset holder 2 while holding down the release button 7.

In this way, the operation of pressing the release operation button 7 and the handset 1
Since it is necessary to perform the operation of removing the handset 1 at the same time, the operation of removing the handset 1 has become troublesome. Furthermore, it is necessary to incorporate parts for the release operation into the handset holder 2, resulting in a complicated structure and an increase in the number of parts.

Therefore, an object of the present invention is to enable the handset to be easily attached and detached without requiring an independent external operation for releasing the movable locking pawl. To provide a telephone with a simple structure in which a handset can be stably fixed.

[Means for solving problems]

A telephone according to the present invention comprises: a handset having a locking hole; a handset cradle having a recess for receiving the handset;
The handset is provided so as to be retractable into the opening provided in the recess and is biased by a spring in the direction of protrusion into the recess. It is equipped with a movable locking pawl that fixes the handset to the handset cradle.

The tip of this movable locking claw has a movable outer inclined surface that comes into contact with the handset when the handset is inserted into the recess, and an inner inclined surface that comes into contact with the handset when the handset is removed from the recess. It is formed to form an acute angle with respect to the direction in which the locking claw protrudes and retracts.

[For production]

In the telephone according to the present invention, when the protruding part of the handset is inserted into the recess of the handset holder, when the receiving part of the handset presses the outer inclined surface of the tip of the movable locking pawl, the movable locking pawl is retracted into the handset cradle against the force of the spring due to the protruding and retracting component of the pushing force. When the receiver of the handset fits into the recess of the handset holder, the movable locking pawl is pushed in the protruding direction by the spring and fits into the locking hole of the handset. A protrusion is secured within a recess in the handset cradle.

On the other hand, when removing the protruding part of the handset from the recess of the handset cradle, the protruding part of the handset uses the force acting on the inner slope of the movable locking pawl to move the movable locking pawl in the retracting direction. Therefore, the movable locking pawl sinks into the handset holder against the force of the spring, and is released from the locking hole of the handset.

In this way, by applying force for attaching and detaching the handset to the outer and inner inclined surfaces of the movable locking pawl, the movable locking pawl is moved inward of the handset holder against the spring force. Since the handset can be immersed in the handset, the handset can be easily attached and detached by simply applying force for attaching and detaching the handset, and the handset can be attached and detached using only one hand.

Moreover, when the handset is installed in the recess of the handset cradle, the movable locking pawl is kept engaged with the locking hole of the handset by the spring force, so that the handset can be stably fixed to the handset cradle. be able to.

Further, since a separate member such as a release button for disengaging the movable locking claw from the locking hole of the handset is not required, the structure of the telephone can be simplified.
