[Embodiment of the invention]

 Hereinafter, embodiments of the mobile phone antenna 1 of the present invention will be described in detail with reference to the drawings. As shown in FIG. 1, the mobile telephone antenna 1 of the present invention is roughly divided into a body 2, a pole 3, a spring holding tube 4, a spring 5, a fixing means 6, a release button 7, and the like. As shown in FIG. 4, the mobile phone antenna 1 is disposed on one side of the case body 8, the body 2 and the release button 7 are disposed so as to be exposed from the case body 8, and the spring holding tube 4 is provided on the case body 8. It is stored in the main body 8 and cannot be seen from the outside. FIG. 4 shows a state when the mobile phone antenna 1 is used. The pole 3 is in an extended state and is held on the body 2 side while protruding from the body 2.

As shown in FIG. 1, the body 2 has a tapered body main body 9 whose diameter is reduced toward the front end, a boss portion 10 and a screw portion 1 formed on the rear end side of the body main body 9. The through holes 12 are formed in these components along the axial direction. Further, a tapered groove 13 is formed at the tip of the body 9, and a concave hole 14 for accommodating the fixing means 6 and the release button 7 described later is formed at an intermediate portion thereof.

The pole 3 is formed of an elongated rod-shaped member, and is slidably supported in the through hole 12 of the body 2. A head 15 is fixed to the tip of the pole 3, and an enlarged portion 16 having a larger diameter than the sliding portion of the pole 2 is formed at the rear end. A ring groove 17 is formed in the sliding portion of the pawl 3 so as to be engaged with the fixing means 6 described later. The head 15 is formed in a tapered shape and is held in contact with the concave groove 13 of the body 2 when the pole 3 is stored.

The spring holding tube 4 is formed of an elongated hollow tube having a bottom surface, and its opening side is fitted to the rear end of the body 2 and fixed to the body 2. On the other hand, the spring 5 is housed in the spring holding tube 4 and is supported by one end thereof in contact with the bottom surface. The other end of the spring 5 contacts the enlarged diameter portion 16 of the pawl 3 and urges the pawl 3 to press it in the extended state. The spring 5 is compressed to the shortest length when the pole 3 is contracted. In this case, the spring 5 is formed from a shape that does not reach the minimum compression length. In this state, the repulsive spring force of the spring 5 does not exceed the locking force of the fixing means 6 described later.

Next, the fixing means 6 will be described with reference to FIGS. The fixing means 6 includes a lock piece 18 and a spring member 19, which are housed in the recess 14 of the body 2. The lock piece 18 has a locking portion 20 that fits into the ring groove 17 of the pawl 3. The pawl 3 is restrained from moving in the axial direction with the locking portion 20 fitted in the ring groove 17. You. The spring member 19 is biased so as to press the lock piece 18 in the direction of fitting the lock piece 18 into the ring groove 17, and is held on the bottom surface 21 of the recess 14.

On the other hand, the release button 7 includes a button body 22 that is held in the recessed hole 14 so as to be able to move in and out, and a locking portion 23 that is formed to protrude from the back side of the button body 22. Has a shape capable of abuttingly engaging with the locking portion 20 of the fixing means 6 when the button body 22 moves in the pressing direction and pressing the locking portion 20 to a position where the locking portion 20 is released from the ring groove 17 of the pawl 3. .

Each of the components of the mobile phone antenna 1 is made of an arbitrary material having an appropriate rigidity. Rust prevention treatment. In addition, it is desirable that a surface treatment for improving the appearance be performed regardless of the material. The release button 7 is desirably formed in a different color so as to be distinguished from other components.

Next, the operation of the mobile phone antenna 1 in use and non-use will be described. FIG. 1 shows a state in which the pole 3 is extended to a used position, and FIG. 2 shows a state in which the pole 3 is stored in the body 2 when the antenna is not used. When the head 15 of the pole 3 in the state of FIG. 1 is pressed, the pole 3 is guided into the through hole 12 of the body 2, and the enlarged diameter portion 16 of the pole 3 is inserted into the body 2 while compressing the spring 5. The fixing means 6 engages with the ring groove 17 of the pole 3 at a position where the head 15 of the pole 3 substantially engages with the concave groove 13 of the body 2. That is, the lock piece 18 of the fixing means 6 is pressed by the spring member 19 and fits in the ring groove portion 17 to restrict the further movement of the pawl 3. Of course, in this case, the locking portion 23 of the release button 7 does not interfere with the ring groove 17. As described above, the pole 3 is housed in the body 2 and is locked and held.

When the mobile phone antenna 1 is used, when the button body 22 of the release button 7 is pressed with the fingertip of one hand, the locking portion 23 causes the locking portion 20 of the fixing means 6 to resist the spring force of the spring member 19. Then, the engagement between the locking portion 20 and the ring groove portion 17 is released. Therefore, the pawl 3 is pressed by the spring reaction force of the spring 5, and the pawl 3 extends from the state of FIG. 2 to the state of FIG. Since the enlarged diameter portion 16 is formed at the rear end of the pole 3, the enlarged diameter portion 16 hits the rear end surface of the body 2, and the pole 3 does not extend any further.

As described above, in the mobile phone antenna 1 of the present invention, the pole 3 is extended by a one-touch operation simply by pressing the release button 7 with one fingertip, and the mobile phone antenna 1 is used. Can be easily done. Further, the storage of the pole 3 can be performed very simply by pressing the head 15 of the pole 3 and engaging the fixing means 6 with the pole 3.
