Description

[Detailed description of the invention]

[0001]

[Industrial applications]

 The present invention relates to an antenna device used for a portable wireless device, a transceiver, and the like, and particularly to a portable wireless device in which a wire antenna is detachably attached to a wireless device housing so that antenna operation corresponding to use of the portable wireless device can be eliminated. The present invention relates to a mechanical antenna device.

[Prior art]

As is well known, an amateur band, a dual-purpose band, and the like of a portable wireless device and a transceiver are widely and generally used. A retractable rod antenna is built into the radio housing of this type of portable radio, and this rod antenna is housed in the radio housing when not in use and pulled out from the radio housing during a call. It is designed to be used in a straightened state.

[0003]

[Problems to be solved by the invention]

 However, such a rod antenna is designed to be pulled out and used during a call, but it is also possible to use the rod antenna without pulling it out in a place where radio waves are good. However, when used in places where radio waves are obstructed or in places where radio wave reception is poor at long distances, the rod antenna is pulled out in a straight line each time it is used. The radio body is handled in this state. For example, if the radio body in this state is stored in a pocket or container. There is a problem that the rod antenna is bent or the antenna part is damaged.

On the other hand, recent mobile phones and the like have been increasingly miniaturized due to intensified pursuit of convenience and cost reduction with the remarkable spread of PDC (Personal Digital Cellular) and PHS (Personal Handy Phone System). For this reason, small-sized pocket-type machines have appeared due to the high integration of electronic circuits such as control circuits and transmission / reception circuits.

On the other hand, since the antenna main body is limited based on the wavelength of the communication radio wave and cannot be simply reduced in size, it is difficult for the antenna main body to incorporate the above-described conventional telescopic rod antenna. It has become.

Therefore, an object of the present invention is to reduce the size of the portable wireless device by eliminating the need for securing a space for housing the antenna inside the wireless device housing, and to reduce the size of the portable wireless device during use. It is an object of the present invention to provide an antenna device for a portable wireless device that can eliminate the troublesome operation of inserting and removing an antenna.

[0007]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention has the following technical means. That is, this will be described using the reference numerals in the accompanying drawings corresponding to the embodiments of the present invention. The present invention relates to a portable wireless device 1 having an antenna connection portion 2 in a part of a wireless device housing 1a. And a wire antenna 3 of a predetermined length having a terminal 4 detachably attached to the antenna connection portion 2 at one end and a detachably attached portion 5 attached to a user at least at the other end. An antenna device for a portable wireless device. According to the above description, the portable wireless device 1 is housed in a part of the user's accessory, for example, in a suit pocket as a dress 10 or in a case 7 locked on a trouser belt 8. Being held. One end of the wire antenna 3 is attached to the antenna connection portion 2 and is extended to a predetermined length, and the attachment portion 5 at the other end is attached to a collar or upper pocket of a Y-shirt, which is a part attached to the user. Can be Normally, one end of the wire antenna 3 is connected to the antenna connection portion of the wireless device casing. However, when the storage position of the portable wireless device 1 is changed or the use of the portable wireless device 1 is terminated. In such a case, the terminal 4 of the wire antenna 3 is appropriately removed from the antenna connection unit 2.

This is an antenna device for a portable wireless device comprising a mechanism, a lock release operation unit 11b for releasing a lock, and a winding mechanism for resiliently winding and storing the unlocked wire antenna 12 therein. . According to the above description, when the wire antenna winder 11 is attached to the antenna connection portion 2 of the wireless device housing 1a, the wire antenna 12 having a predetermined length is attached before the portable wireless device 1 is used. It is pulled out against the force, locked by the lock mechanism, and set at the position desired by the user. When the portable wireless device 1 is not used, when the attaching portion 5 is removed and the unlocking operation portion 11b is operated, the wire antenna 12 is automatically wound up by the winding mechanism and the wire antenna 12 is inserted into the case 11a. Is stored in. Therefore, the wire antenna 12 can be appropriately pulled out to a predetermined length, and the pulled-out wire antenna 12 can be automatically locked at a desired position by a lock mechanism. When the portable wireless device 1 is not used, when the attachment portion 5 is removed from a part of the clothing 10 of the user 6, the wire antenna 12 is automatically operated by operating the lock release mechanism 11b. The wire antenna 12 can be retracted and stored in the case 11a, and the wire antenna 12 can be easily expanded and contracted and locked.

Further, in the present invention, the portable wireless device 1 is configured in a shoulder type, and an attachment portion of the wire antenna 3 is detachably attached to an attachment portion provided on a part of the shoulder belt. It is an antenna device for a portable wireless device. According to the above description, when the portable wireless device 1 is of a shoulder type, the wire antenna 3 of a predetermined length in which the terminal 4 is connected to the antenna connection portion 2 of the portable wireless device 1 is a part attached to the user. When crawled along the shoulder belt, the device is used in a state where at least the attachment portion is attached to the attachment portion of the shoulder belt. Accordingly, since the wire antenna 3 is crawled along the shoulder belt, the wire antenna 3 is integrated with the portable wireless device 1, so that even when the portable wireless device 1 is moved, the wire antenna 3 can be used without detaching the wire antenna each time. The wire antenna 3 can be held without slack, and can be protected by the shoulder belt without being noticeable in appearance.

Further, the present invention is an antenna device for a portable wireless device in which a mounting portion of the wire antenna 3 is formed by a clip. According to the above, the terminal 4 of the wire antenna 3 is connected to the antenna connection portion 2 of the portable wireless device 1 carried by the user 6, and the clip at the other end is attached to a part attached to the user. Therefore, since the attaching portion of the wire antenna 3 is formed by the clip, it can be selectively attached to a part attached to the user as appropriate.

Further, the present invention is an antenna device for a portable wireless device in which the attachment portion of the wire antenna 3 is formed of a hook-and-loop fastener. According to the above, a surface fastener attached to at least the end of the wire antenna 3 is attached to the surface fastener by attaching the surface fastener to a part of the belt accompanying a use, for example, a shoulder belt. You. Therefore, since the attachment portion to which the end of the wire antenna 3 is attached is formed of a hook-and-loop fastener, the wire antenna 3 can be used without any sense of incongruity in a flat manner.
