DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an extendable and retractable antenna for a portable telephone set which can be bent when not in use.

[0002]

2. Description of the Related Art Conventionally, this type of antenna is configured to extend in the axial direction from the main body of the portable telephone when in use, and to be stored in the main body of the portable telephone when not in use.

[0003]

The sensitivity of a conventional mobile phone antenna is reduced when the antenna is contracted inside the body when not in use, and the sensitivity is reduced even when the antenna is placed sideways. There was a drawback that radio waves could not be received.

The present invention has been made in view of the above-mentioned conventional drawbacks,
An object of the present invention is to provide an antenna for a mobile phone that can position the antenna in an optimal state for receiving radio waves even when in use or in a standby state, and that can be stored in a small size while receiving radio waves with high sensitivity. And

The above and other objects and novel features of the present invention will become more completely apparent when the following description is read in conjunction with the accompanying drawings. However, the drawings are for explanation only, and do not limit the technical scope of the present invention.

[0006]

To achieve the above object, the present invention provides an antenna mounting bracket screwed and fixed to a screw-shaped antenna mounting section connected to a power supply section of a portable telephone.
A mobile phone antenna is composed of a connection metal fitting that can be bent at the distal end attached to the antenna mounting metal, and a telescopic antenna body that is mounted so as to be able to be bent at the connection metal fitting.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail with reference to the embodiments shown in the drawings.

In the first embodiment of the present invention shown in FIGS. 1 to 6, reference numeral 1 denotes a mobile phone of the present invention which is screwed and fixed to a screw-shaped antenna mounting portion 3 connected to a power supply portion of a mobile phone 2. The antenna for a mobile phone, the antenna for a mobile phone 1
The antenna mounting bracket 4 is screwed and fixed to the antenna mounting section 3, a connecting bracket 5 rotatably mounted on the antenna mounting bracket 4 and capable of bending a tip portion by approximately 90 degrees. And an extendable antenna body 6 attached to the distal end portion so as to be able to bend substantially 90 degrees.

The antenna mounting member 4 is formed of a metal material capable of transmitting radio waves. The antenna mounting member main body 8 has a screw portion 7 screwed and fixed to the antenna mounting portion 3 at a lower portion. A concave portion 10 having a cutout groove 9 formed on the upper portion of the antenna mounting member main body 8 so that the lower end portion of the connection metal member 5 can transmit a radio wave and can be rotatably fitted thereto; And a threaded portion 11 formed on the outer peripheral portion near the lower portion of the upper portion.

The connection fitting 5 is formed of a metal material capable of transmitting radio waves, and has a fitting piece 12 formed rotatably in the recess 10 at the lower part, and a U-shaped part at the upper part. Lower connecting device main body 1 on which mounting portion 13 is formed
4. A lower connector 17 comprising a flange-like stopper piece 15 formed on the outer peripheral portion of the lower connector main body 14 near the center thereof, and a screw hole 16 formed in the mounting portion 13; A mounting piece 2 having a hole 19 that can be inserted into the mounting portion 13 and rotatably mounted with a screw 18
0 is formed, and a U-shaped antenna main body mounting portion 21 is formed on the upper portion.
The upper connector 24 formed of an upper connector main body 22 formed with a hole, a screw hole 23 formed in the antenna main body mounting portion 21, and an inner portion mounted so as not to come off from the stopper piece 15 of the lower connector 17. A cap 26 having a screw portion 25 that can be screwed and fixed to the screw portion of the antenna mounting bracket 4 at the lower end of the wall surface.

The antenna body 6 includes a fixed antenna member 27 attached to the connection member 5, four telescopic antenna members 28, 28, 28, 28 which can expand and contract above the fixed antenna member 27, An antenna main body mounting piece 30 having a hole 29 that can be inserted into the antenna main body mounting portion 21 formed below the fixed antenna member 27 and rotatably mounted with the screw 18.

The mobile phone antenna 1 having the above configuration can be mounted by removing an antenna preset on the mobile phone 2 and screwing and fixing an antenna mounting bracket 4 to the antenna mounting section 3. When used, it is natural that the antenna main body 6 can be extended to receive radio waves as in the conventional case.
When the antenna body 6 is used in a contracted state, the antenna body 6 protrudes outward from the mobile phone 2, so that the radio wave can be accurately received without lowering the sensitivity.
When the mobile phone 2 is placed sideways on a table or the like when waiting for an incoming radio wave, as shown in FIG. 6, the connection fitting 5 or the antenna body 6 is bent upward,
Since the antenna main body 6 can be extended, the antenna main body 6 can be always in the best condition for receiving radio waves, so that radio waves can always be received with high sensitivity.

When storing the antenna body when not in use,
Since the upper connector 24 of the connection fitting 5 and the antenna main body 6 can be rotated and bent so as to be in close contact with the front, side, or back portion of the mobile phone 2, the antenna main body 6 is located outside the mobile phone 2 and has a sensitivity. Can be stored in a small state in a state where reception can be performed without a decrease.

[0014]

Next, different embodiments of the present invention shown in FIGS. 7 to 9 will be described. In the description of the different embodiments of the present invention, the same components as those of the first embodiment of the present invention are denoted by the same reference numerals, and duplicate description will be omitted.

The second embodiment of the present invention shown in FIGS. 7 and 8 is mainly different from the first embodiment of the present invention in that the lower connecting member main body 14A is fixed to the concave portion 10. At this point, the antenna 1A for a mobile phone constructed as described above bends the antenna body 6 toward the front, side, or back of the mobile phone 2 in a state where the antenna mounting bracket 4A can be screwed and fixed to the antenna mounting portion 3. Since the positioning can be performed, the same operation and effect as those of the first embodiment of the present invention can be obtained.

[0016]

As apparent from the above description, the following effects can be obtained in the present invention.

(1) An antenna mounting bracket screwed and fixed to a screw-shaped antenna mounting section connected to a power supply section of a mobile phone, and a connecting bracket capable of bending a tip mounted on the antenna mounting bracket. Since the antenna body can be bent and attached to the connection fitting so as to be able to be bent, the antenna body can be rotated and bent to a position where radio waves can be reliably received. Therefore, radio waves can always be received in a high sensitivity state without lowering the sensitivity.

(2) According to the above (1), the antenna body can be bent so as to be in close contact with the portable telephone, so that the antenna body can be stored in a small state in which radio waves can be received without lowering sensitivity. it can.

(3) According to the above (1), the antenna mounting bracket, the connecting bracket mounted on the antenna mounting bracket, and the antenna main body mounted so as to be able to be bent on the connecting bracket are provided. , With a simple structure, easy and inexpensive to manufacture,
