BEST MODE FOR CARRYING OUT THE INVENTION

 Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

FIGS. 1 and 2A show a case 2, a guide 6, an upper stopper 11 and a lower stopper 12, a latching groove 5, an upper pushing plate 9 and a lower pushing plate 10, a spring 8, an upper operation according to an embodiment of the present invention. The pin 13, the lower operation pin 14, and the button 20 are constituted by an extended pusher 7, an antenna 4, and the like.

That is, the case 2 is formed in a form in which one side is opened, and is fixedly provided on one side inside the communication device.

Moreover, the guide 6 is fixed to the case 2, and the engaging groove 5 is selectively formed in the upper stopper 11 and the lower stopper 12 that are rotatably connected to the upper and lower portions of the guide 6. It is equipped so that it can be hung and fixed.

That is, the upper and lower stoppers 11 and 12 are brought into contact with the locking projections 5 b and the lower end surface of the locking groove 5 in a pressurized state, so that the locking groove 5 is fixed in a state where the locking groove 5 is lifted and lowered.

Further, both ends of the spring 8 are fixed to an upper pushing plate 9 and a lower pusher plate 10 for selectively hitting the upper and lower sides of the engaging groove 5, and the upper stopper 11 and the lower stopper 12 are selected. An upper operating pin 13 and a lower operating pin 14 which are pushed and locked and unlocked are formed in the pusher 7 in an extended state.

That is, the upper and lower stoppers 11 and 12 are alternately locked by the upper and lower operation pins 13 and 14 in response to the pusher 7 getting on and off.

The pusher 7 has a button 20 provided so as to be exposed to the outside of the communication device, and the engaging groove 5 is connected to a lower end of the antenna 4. The antenna 4 is built in the case 2 so as to be able to penetrate and extend the communication device and the upper side of the case 2 at the same time.

With this configuration, as shown in FIGS. 2A and 2B, with the antenna 4 immersed in the case 2 and lowered to the lowermost position, the button 20 is already lowered by the user's operation. In this state, the pusher 7, the upper and lower pushing plates 9, 10 and the like together with the button 20 are maintained in a lowered state.

At this time, the lower groove 12a of the antenna 4 is sandwiched between the lower stoppers 12a.
Is kept in a lowered state because of locking.

In this state, when the user presses the button 20 to use the antenna 4, the upper pushing plate 9 is lifted while being lifted together with the integrated pusher 7.

At this time, the lower pushing plate 10 supports the lower end of the engaging groove 5, and the lower stopper 12 is sandwiched and fixed by the engaging groove 5 a of the engaging groove 5.

Therefore, the spring 8 accumulates elastic energy while being pulled in a state where the lower end thereof is fixed by the pusher 7.

Subsequently, when the pusher 7 rises by a predetermined distance, the operating pin 14 on the left side of the pusher 7 rotates the lower stopper 12 to pull out the lower stopper 12 from the locking groove 5 a and lock the locking groove 5. Release the state.

When the locking of the locking groove 5 is released, the lower pushing plate 10 supporting the locking groove 5 is released, and at the moment due to the accumulated elastic force of the spring 8, the locking groove 5 is lifted by the lifting force. .

At the same time, the antenna 4 integrated with the locking groove 5 also rises and is exposed outside the case 2.

Subsequently, as shown in FIGS. 2C and 2D, the antenna 4 is raised to the limited height, and the lower end of the locking groove 5 is hooked on the upper stopper 11, and the locking groove 5 is fixed. At the same time, the antenna 4 integrated with the locking groove 5 is fixed and maintained in the raised state.

On the other hand, the upper pushing plate 9 raised by the pusher 7 is locked while being hooked on the locking projection 5 b of the locking groove 5 of the antenna 4, and at the same time, the pushed pusher 7 is lowered by receiving the elastic force of the spring 8. The pusher plate 10 is locked at that position (upper end).

The user can use the mobile phone with the antenna 4 and other components raised as described above.

As shown in FIG. 2E, when the use of the mobile phone is completed, the user operates the button 20 to lower the antenna 4 into the case 2 again. Only the following steps are performed, which are the same as those described above.

As shown in FIG. 2F, when the user operates the button 20 which has been moved upward, the pusher 7 integrated with the button 20 moves down in the state of FIG. And the spring 8 is extended along the lower pushing plate 10.

When the pusher 7 is lowered by a predetermined distance, the operating pin 13 of the pusher 7 rotates the upper stopper 11 to release the locking state of the locking groove 5.

At this time, while the upper pushing plate 9 is in a free state, the engaging protrusion 5 b is hit by the elastic force accumulated in the spring 8 to lower the engaging groove 5.

Then, the antenna 4 is also lowered and inserted into the case 2.

The antenna 4 is lowered to the lowermost end and is locked while the lower stopper 12 is interposed between the locking grooves 5 a and the locking grooves 5 a, thereby maintaining the lowered state.

At this time, the lower pushing plate 10 lowered by the pusher 7 is locked while hanging on the bottom surface of the locking groove 5 of the antenna 4, and at the same time, the pusher 7 is moved to its position ( lower end)
Is maintained in the locked state.

Therefore, the pusher 7 and the extended button 20 are kept at a state of being moved to the lowermost position and waiting for reuse of the mobile phone.

FIG. 3 shows another embodiment of the present invention in which a contact ring 32 capable of conducting current is fixed to the button 20, and a SEND contact to which such a contact ring 32 is selectively contacted. And a buttonhole 38 in which the END contacts 34 and 36 are open to the communication device.
It is formed on the upper and lower sides of the peripheral portion so as to correspond to the position of the contact ring 32.

That is, when the button 20 is moved on and off, the SEND contact and the END contacts 34 and 36 are selectively connected by the contact ring 32, and an electric signal generated by current conduction is input to the main circuit to input the electric signal to the main circuit. It becomes a 'SEND' or 'END' state in which the start and end of transmission and reception are performed by the calculation.

Further, the SEND contact and the END contact 34, 36 can be volume up / down contacts. When the button 20 is formed so as to move left and right, the contact ring 32 of the button 20 can be used as a contact. By turning on / off 34 and 36, the electric signal generated thereby is inputted to the main circuit, and the volume up / down can be performed by the operation in the main circuit.

In addition, the antenna 4 is provided at the protruding hole of the antenna 4 formed in the communication device.
The head portion may be formed in a structure in which a concave groove 17 that can be seated in a immersed state is formed.

As shown in FIG. 4, the antenna 4 is formed into a shape having a symmetrical gear portion 18 ″, and a pair of reduction rollers 18, 18 ′ interlocked at a position symmetrical to the antenna portion 4 are turned around the case 2. It is movably mounted to reduce the speed at which the antenna 4 is pulled in and out.

As shown in FIG. 5, a vertical hole is formed in the button 20, and a bar 48 vertically long is provided in the button 20, and the bar 48 is spring-loaded by a spring 50 through a through hole of the bar 48. At the center of the bar 48, a safety button 52 partially protruding through the center of the button 20 is sandwiched, and is sandwiched between grooves 40, 42 recessed in the upper and lower sides of the inner wall body around the buttonhole 38. A pair of locking projections 44, 4
6 are formed at both ends of the bar 48, respectively.

That is, only when the safety button 52 is pressed, the locking projections 44, 46 of the bar 48 are disengaged from the grooves 40, 42 formed on the inner surface of the wall of the case 28 of the communication device. Can move up and down, and the locking projections 4 of the bar 48
Reference numerals 4 and 46 prevent the button 20 from being moved again by being caught by the spring elasticity at the neutral position of the button 20 and re- sandwiched by the groove 40 formed on the inner surface of the communication device wall.
