FIG. 1 is an external perspective view showing an embodiment of the present invention, FIG. 2 is a front view showing a lock knob mounting guide hole of a lower panel in this embodiment, and FIG. 3 is a closed state of this embodiment. (A) is a cross-sectional view, (b) is a front view,
(C) is a longitudinal sectional view, FIG. 4 shows an open state of this embodiment, (a) is a transverse sectional view, (b) is a front view, and (c) is a longitudinal sectional view.

The structure of the foldable portable telephone body 1 according to this embodiment is configured such that an upper panel 2 and a lower panel 3 are openably and closably connected via a hinge 1a. The side face of the upper panel 2 is provided with a hook-shaped notch recess 2a that is substantially L-shaped from the lower end face (FIG. 1).

On the other hand, on the side surface of the lower panel 3, a substantially L-shaped mounting guide hole 3a corresponding to the position and shape of the cutout recess 2a of the upper panel 2 is provided (FIGS. 1 and 2). A lock knob 4 having a substantially L-shaped protrusion 4a having a hook-like tip and engaging with a hook-like portion of the cutout recess 2a is inserted into the guide hole 3a by a shaft 4b having a vertically extending portion. The lock knob is fixed by fitting the shaft 4b to the support member 5 inside the lower panel 3 (FIGS. 3 and 4). As a result, the lock knob 4, the projecting piece 4a and the support member 5 can move according to the substantially L-shaped shape of the mounting guide hole 3a.

A projection shaft 5a is provided on a side surface of a support member 5 which is movable together with the lock knob 4 in the direction of arrow C on the hinge portion 1a side, and a spring (A) 6 is fitted thereto. (FIG. 3A). Rib 3b
Is provided with a guide elongated hole 3c, into which the projection shaft 5a is inserted and movable, in an oval shape. The spring (A) 6 urges the projecting piece 4 a via the support member 5 in the direction opposite to the arrow C. The support member 5 has a stepped shaft 5b on the side opposite to the engagement with the lock knob 4, and a spring (B) 7 is provided between the stepped shaft 5b and the bracket 3d on the bottom surface of the lower panel 3. Hook (FIG. 3 (c)). The spring (B) 7 urges the projecting piece 4 a downward (in the direction of arrow D) via the support member 5.

As described above, in this embodiment, the upper panel 2 has the substantially L-shaped hook-shaped notch concave portion 2a, and the lower panel 3 has the lock knob 4, the support member 5, and the projecting piece 4a. It has a spring (A) 6 and a spring (B) 7.

The operation of this embodiment having the above-described configuration will be described below. First, in the initial state of this embodiment, as shown in FIGS. 1 and 3A and 3B, the upper panel 2 and the lower panel 3 are closed, and the lock knob 4 is moved by a spring (A) 6 by an arrow C. , The projection 4a is engaged and locked with the hook-shaped portion of the cutout recess 2a of the upper panel 2, and the upper panel 2 and the lower panel 3 are closed.

The operation of releasing the engagement from the state in which the upper panel 2 and the lower panel 3 are closed as described above is as follows.

As shown in FIG. 4, when the lock knob 4 is moved in the direction of arrow C against the urging force of the spring (A) 6,
The shaft 4b of the lock knob 4 moves in the direction of arrow D from the corner along the shape of the substantially L-shaped mounting guide hole 3a, and the projection 4a engages with the notch recess 2a of the upper panel 2. Is released. At this time, the lock knob 4, the projection 4a, etc. all move toward the lower panel 3. Meanwhile, the spring (A) 6 is compressed in the direction of arrow C, and the protruding shaft 5a of the support member 5 moves in the direction of arrow D in the elongated oval guide hole 3c of the rib 3b. As shown in FIG. 4C, the spring (B) 7 contracts at the portion that has been extended by the urging force in the direction of arrow D, and assists the lock knob 4 to move in the direction of arrow D via the support member 5. The engagement of the projection piece 4a with the upper panel 2 is released.

On the other hand, the upper panel 2 and the lower panel 3
Is engaged in the closed state by performing the operation opposite to the above-described operation, that is, the lock knob 4 is moved from the state shown in FIG. 4 into the mounting guide hole 3a against the urging force of the spring (B) 7. Is moved in the direction opposite to the arrow D, and is moved in the direction opposite to the arrow C in combination with the urging force of the spring (A) 6 from the corner of the mounting guide hole 3a, so that the projection 4a becomes the notch recess 2a of the upper panel 2. This is done by engaging and locking to the hook-shaped part of.

In the embodiment described above, the spring (A) 6 is preferably a compression coil spring, and the spring (B) 7 is preferably a tension coil spring.

[0018]

As described above, the present invention relates to a structure of a foldable portable telephone having an upper panel and a lower panel which are openably and closably connected via a hinge portion. On the other hand, a projection is provided at the tip of a lock knob that moves along the guide hole on the side surface of the lower panel, and the projection engages with the hook-shaped recess of the upper panel to close it. By disengaging and setting to the open state, unlike the conventional case of fixing with a magnet, there is no effect on the characteristics due to the magnetic force lines on the internally mounted components, and the internal mounted components are not affected. There is no need to protect with a shield, and effects such as not being restricted by mounting can be obtained.
