DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lock mechanism for a telephone, such as a portable telephone, in which a transmission section is foldably and extendably attached to a main body by a hinge. The present invention relates to a mechanism for locking and unlocking a talk section with respect to a main body section.

[0002]

2. Description of the Related Art In recent years, various types of telephones have been developed in accordance with their usage.
Japanese Patent Application Publication No. 259156 discloses a telephone as a portable telephone such as a cordless telephone in which a transmitting unit is foldably and extendably attached to a main unit having a button dial key by a hinge. In a non-use state, such a telephone can be made compact by folding the transmission section, so that it is suitable for carrying.

[0003] In the above-mentioned folding telephone, it is necessary to lock and fix the transmitting section to the main body in a folded state. Therefore, as shown in FIG. 7, the main body (not shown) is used. A lock release operation button A, a slide member B that is slid by the button A, and a lock claw C integrally formed with the slide member B, while a lock recess E is formed in the transmission section D, When the talk section D is folded, the lock claw C is engaged with the locking recess E by the force of the spring, and the locked state is maintained. When the lock release operation button A is pressed in the direction of arrow a from this state, A lock mechanism has been considered in which the slide member B moves against the spring and the lock claw C moves to a position where it comes off from the locking recess E.

[0004]

However, in the above-described lock mechanism, when the transmitting section D is folded, the lock claw C is automatically engaged with the lock concave portion E to lock. Therefore, cam surfaces F and G are formed at the tip of the locking claw C and the entrance of the locking concave portion E, and when the transmitting section D is closed, the two cam surfaces F and G come into contact with each other, and the slide member B and the sliding member B Since the lock claw C slides in the unlocking direction, and thereby the lock claw C is guided to the entrance H of the locking recess E so that the above-described engagement is performed,
Release operation button A by the movement of the slide member B or the like
Unnecessary movements appear outside the main body due to the movement of the body.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a telephone lock mechanism in which a movement during an automatic lock operation does not appear outside as a movement of a lock release operation button.

[0006]

That is, according to the present invention, a transmitter is attached to a main body so as to be foldable by a hinge, and an unlock operation button is provided on one of the main body and the transmitter. A lock claw that is slid in the unlocking direction is provided, and the lock claw is engaged on the other side in a folded state of the transmission section, and the lock claw is disengaged by the slide of the lock claw. A lock mechanism for a telephone provided with a recess,
A slide member that slides integrally with the lock release operation button is provided, and a thin portion that can be bent and deformed in a direction substantially perpendicular to the sliding direction is formed at the tip of the slide member. A cam surface provided with the lock claw and engaging the lock claw with the lock recess while contacting the lock claw at the time of folding the transmitting section to deform the thin portion in the vicinity of the lock recess. Is formed.

[0007]

According to the above construction, when the transmitting section is folded from the extended state, the locking claw comes into contact with the cam surface on the locking concave side, thereby causing the thin portion of the sliding member to slide on the sliding member. The lock member is bent and deformed in a direction substantially perpendicular to the direction, and the deformation causes the lock claw to be engaged with the locking concave portion, so that the slide member does not slide during automatic locking.

[0008]

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 shows a portable telephone 1, and the telephone 1
Has a main unit 2 and a transmitting unit 3, and the main unit 2 is provided with an operation unit 4 having various key switches such as button dial keys, a speaker 5, an antenna 6, and the like. A transmitting section 3 having a built-in microphone is attached by a hinge 7 so as to be foldable and extendable.

A push button type unlocking operation button 8 is provided on a side surface of the main body 2 in a protruding state, and a slide member 9 (see FIG. Guide member 1)
It is arranged so as to be slidable in the direction of arrow X while being guided by zero. In that case, a portion of the slide member 9 closer to the tip end than the guide member 10 is formed into a thin portion 11 that can be bent and deformed in an arrow Y direction substantially perpendicular to the slide direction,
A lock claw 12 is formed on a side surface of the thin portion 11 and on a side opposite to the direction in which the thin portion 11 can be flexibly deformed. The lock claw 12 protrudes out of the main body from an opening 2A provided in the main body 2.
The cam surface 13 with which the transmitting unit 3 contacts when the transmitting unit 3 is folded is attached to the protruding tip of the lock claw 12.
Is formed. In addition, a spring 14 is provided between the lock release operation button 8 and the guide member 10, and the whole of the lock release button 8, the slide member 9, and the lock claw 12 is moved in the direction of the arrow X by the force of the spring 14. It is configured to be biased in the opposite direction.

A lock recess 15 is formed in the transmitting section 3 at a position where the transmitting section 3 comes into contact with the lock claw 12 when the transmitting section 3 is folded. In this case, as shown in FIG. 6, the locking claw 12 is
And the entrance 15B at which the lock claw 12 is disengaged from the locking recess 15 by the movement of the transmission section 3 in the extension direction when the lock claw 12 is moved in the X direction. And a cam surface 16 is formed beside the entrance portion 15B and at the corner of the transmitting section 3 on the inner rear portion 15A side. In that case, the cam surface 16 of the transmitter 3
Is located at a position where it comes into contact with the cam surface 13 of the lock claw 12 when the transmitting section 3 is folded,
By the contact of 6, a force is generated in the lock claw 12 to deflect the thin portion 11 in the direction of the arrow Y.

In the portable telephone 1 constructed as described above, when the transmitting section 3 is folded from the extended state shown in FIG. 3, the two cam surfaces 13 and 16 come into contact as shown in FIG. That is, the thin portion 11 of the slide member 9 is indicated by an arrow Y
The locking claw 12 moves in the direction of being retracted into the main body, and moves over the transmitter side cam surface 16 by this movement, and then moves in the returning direction to engage with the inner back part 15A of the locking recess 15. Thus, the transmission unit 3 is locked. Therefore, at the time of this automatic lock, the slide member 9 does not perform the slide motion in the direction opposite to the arrow X direction,
The lock release operation button 8 does not show unnecessary movement.

When the unlocking operation button 8 is pressed from the above-mentioned locked state, the lock claw 12 located at the position shown by the dashed line in FIG. Will be canceled.

[0014]

As is apparent from the above description, according to the present invention, when the transmitting section is folded from the extended state, the lock claw comes into contact with the cam surface on the side of the lock concave portion, thereby causing the slide. Since the thin portion of the member is bent and deformed in a direction substantially perpendicular to the sliding direction of the slide member, and this deformation causes the lock claw to be engaged with the locking recess,
No sliding movement of the sliding member occurs at the time of automatic locking, so that unnecessary movement of the unlocking button can be eliminated. Further, the number of movements of the slide member in the sliding direction is halved as compared with the conventional device shown in FIG. 7, so that the life of the spring biasing the slide member in the direction opposite to X can be extended.
