Abstract

PURPOSE:To prevent an electric cord from being damaged at the time of opening/closing the lid body of the portable telephone set by preventing the lid body from being closed with great force in the full open state. CONSTITUTION:At one terminal part of a main body 10 of a speaker, a pair of fitting pieces 40 and 40 are installed so as to be moved in the pivotal shaft of a lid body 20, and a shaft 50 is projected from the respective fitting pieces 40 to the side direction. A pair of bearings 21 and 21 are projected from the lid body 20 pivotally supported by the main body 10 of the speaker, and the bearings 21 are faced to the head part of the shaft 50. A projection 70 is protruded from the bearing 21, and an escape groove and a lock groove to be fitted to the projection 70 in the state of completely closing and opening the lid body 20 are formed on the head face of the shaft 50. An electric cord 91 to connect a transmission microphone 90 of the lid body 20 and the main body 10 of the speaker passes a through hole 51 bored at the shaft 50.

When the lock mechanism is released, the lid body (20) may be suddenly opened, which may hit the human body and cause injury. Further, when the lid body (20) is open, since there is no locking mechanism, the lid body (20) is unstable and easy to move and inconvenient when using the mobile phone. The latter example is provided to solve this problem. In the latter example, the torsion load of the torsion spring is applied to the lid body (20), and the lid body (20) is biased in the closing direction. Since the lid body (20) is opened while resisting the biasing force of the torsion spring, the return force of the torsion spring becomes maximum when the lid body (20) is fully opened. Therefore, the lid (20)
In the fully open position, the phone body (10) and the lid body (20) are locked, and the lid body (20) is shocked and the lid body ( 20) swiftly rotates in the closing direction,
There is a problem that (20) is damaged or the collision noise is loud. The present invention, the lid body (20) can start to open smoothly, and in the state where the lid body (20) is fully opened, the lid body (20) does not easily move in the closing direction, To aim.

When the lid (20) is rotated in the opening direction from the state where it is in contact with the end surface (53b) in the opening direction, the tip of the protrusion (70) and the inclined surface (54) of the clearance groove (53) are in contact, and the protrusion Since the tip of (70) climbs up the inclined surface (54), the shaft (50) and the fitting piece (40) are pushed into the inside of the telephone body (10). Both mating pieces (40)
In the state where the 1) and the recessed part (62) are fitted together, the elasticity of the protruding piece (60) urges the spring to the side, so that the tip end surface of the protrusion (70) and the tip end surface of the shaft (50) are The shaft (50) abuts and slides while being pressed by the protrusion (70). Therefore, when the lid body (20) is opened 45 degrees or more from the closed state, it is opened against the returning force of the torsion spring (80) and the friction between the shaft (50) and the protrusion (70).

The projection (70) fits into the locking groove (52), and the projection (70) and the locking groove (52) are locked. The friction between the protrusion (70) and the shaft (50) is released, and the lid (20) is not subjected to a lateral pressure load. At this position, the rotation of the lid body (20) is stopped. As described above, the engaging groove (52) has the protrusion (70) and the shaft (50).
It is provided so as to be able to rotate 30 ° with respect to the center of the projection, but the projection (70) moves in the closing direction of the lid (20) of the locking groove (52) due to the torsional load of the torsion spring (80). Edge (5

支障になったり、電線(91)を傷つける虞れがない。(Effects of Embodiment) As described above, when the lid body (20) is in the state of starting to open, the projection (70) fits in the clearance groove (53) with a margin, and the lid body (20) is Does not receive lateral pressure load due to the elastic force of the fitting piece (40). Therefore, it is possible to start opening the lid body (20) smoothly. While the lid (20) is being opened, the torsion load of the torsion spring (80) and the lateral pressure load of the fitting piece (40) are applied. In the fully opened state, the protrusion (70) fits into the locking groove (52) and the torsion spring (8
It is pressed against the edge (52a) of the locking groove (52) by (0). In the state where the opening is completed, the return load of the lid body (20) by the torsion spring (80) becomes maximum, and the lid body (20) easily returns. Then, in order to close the lid body (20) from the opened state, it is necessary to have a force against the friction of the fitting piece (40) due to the lateral pressure load. Therefore, with the lid body (20) fully opened, the lid body (2
Even if the projection (70) and the locking groove (52) are disengaged from each other due to an impact on (0), the lid (20) does not close vigorously and the lid (20) does not close.
It does not damage (20) or generate a collision noise. Furthermore, the electric wire (91) passes through the through hole (51) of the shaft (50),
It is connected to the phone body (10). That is, when the lid body (20) is opened and closed, there is no risk that the lid body (20) will pinch the electric wire (91), which will hinder the opening and closing of the lid body (20) or damage the electric wire (91).

In the above embodiment, the protrusion (70) on the lid (20),
Although the locking groove (52) and the clearance groove (53) are provided on the shaft (50), the protrusion (70) is positioned on the shaft (50) and the locking groove (52) and the clearance groove (53) are covered ( 2
It is also possible to provide it in 0). Further, in the above-mentioned embodiment, the range in which one hand can rotate is set to about 45 °,
The angle can be variously changed in consideration of operability. It is also possible to narrow the angle of the locking groove (52) so that the lid body (20) does not easily move after the lid body (20) is opened. Furthermore, as means for applying a lateral load to the lid body (20),
Instead of fitting the two protrusions (60) (60) together, it is possible to insert a push spring between the cylindrical parts (43).
