Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a transmitter such as a radio control device for remotely controlling a controlled object or a receiver such as a radio, and more particularly to an antenna mounting structure of the transmitter / receiver.

[0002]

[Prior Art]

 In a transmitter such as a radio control device, an antenna is arranged on the upper surface of the transmitter for transmitting radio waves. Some radio control device transmitters allow the operator to freely change the direction of the antenna as necessary. FIG. 4 shows a conventional antenna mounting structure in which the direction of the antenna can be freely changed. According to this mounting structure, the substantially spherical ball member 10 is provided with the recess 11 for mounting the antenna, and the base of the antenna 12 is screwed into the screw fixed to the recess 11 to mount the antenna 12. .. Then, the ball member 10 is rotatably held by the substantially cylindrical antenna holder 13 integrated with the transmitter case and the ball seat 14 having a concave spherical surface, and the ball clamper 15 holds the ball member 10 through the ball seat 14. The ball member 10 is pressed against the antenna holder 13. The ball member 10, the ball seat 14, and the ball clamper 15 are made of a metal material (aluminum), and the antenna 12 is electrically connected to the circuit board in the transmitter via the ball clamper 15. With this mounting structure, the antenna 12 can be removed as shown in FIG. 5, and the antenna 12 can be removed and stored when the transmitter is stored in the case, and the storage space can be saved.

[0003]

[Problems to be solved by the device]

 By the way, if the antenna can be removed like the transmitter of the radio control device with the above-mentioned antenna mounting structure, the storage space can be saved, but it takes time and effort when attaching and detaching, and the antenna and the transmitter body are separated. If you do, you may lose the antenna.

An object of the present invention is to allow an antenna to be housed in a transmitter / receiver main body in an antenna mounting structure that rotatably supports the antenna via a ball member.

[0005]

[Means for Solving the Problems]

 In the antenna mounting structure of the transmitter / receiver according to the present invention, the base of the antenna is supported by the ball member, and the antenna is rotatably held by the holder of the transmitter / receiver via the ball member. In the antenna mounting structure for a transmitter / receiver, a through hole for supporting the antenna is formed in the ball member, a locking recess is formed in a base portion of the antenna, and a locking recess is formed in the ball member. There is a lock member that can be released.

[0006]

[Action]

 The antenna can freely rotate with respect to the holder of the transmitter / receiver via the ball member. When the antenna is pushed into the through hole of the ball member, the engagement between the locking recess of the antenna and the lock member on the side of the through hole is released, and the antenna is housed inside the device through the through hole.

[0007]

【Example】

 1 and 2 show the antenna mounting structure of the first embodiment. The antenna holder 13 and the ball clamper 15 have the same shape as the conventional one, but the through hole 2 is formed in the ball member 1 of the present embodiment so as to extend substantially through the center. A lock member 3 also serving as an antenna terminal is arranged at one end of the through hole 2 so as to project toward the center of the through hole 2. One end of this lock member 3 is fixed to the ball member 1, and the other end of which is formed in a substantially key shape has a predetermined elasticity in a groove 5 as a locking recess formed circumferentially in the base of the antenna 4. It is designed to engage with force. A through hole 7 corresponding to the through hole 2 of the ball member 1 is formed in the ball seat 6 of this embodiment.

When the antenna 4 is used, as shown in FIG. 1, the lock member 3 is engaged with the groove 5 in the base portion of the antenna 4 so that the antenna 4 is supported by the ball member 1. The antenna 4 can freely rotate with respect to the antenna holder 13 and the ball seat 6 via the ball member 1.

By providing a storage space for the antenna 4 in the main body of the transmission / reception device, the antenna 4 can be stored in the main body when the antenna 4 is not used. That is, as shown in FIG. 2, when the antenna 4 is pushed inward of the through hole 2, the engagement between the lock member 3 and the groove 5 is released, and the antenna 4 slides through the through hole 2 to transmit / receive the signal. It fits in the storage space inside the body.

FIG. 3 shows an antenna mounting structure of the second embodiment. This embodiment is different from the first embodiment in the structure of the lock member and the shape of the ball member. A holding hole 24 is formed on the inner peripheral surface of the through hole 22 of the ball member 21. A spring 25 is provided in the holding hole 24 so that the ball 23 as a lock member provided at the opening of the holding hole 24 abuts the outer peripheral surface of the antenna 4 with a predetermined elastic force of the spring 25. Is becoming

According to the present embodiment, the ball 23 engages with the groove 5 of the antenna 4 by the elastic force of the spring 25, so that the antenna 4 is fixed to the ball member 21. When the antenna 4 is pushed in the direction of the through hole 22, the ball 23 is removed from the groove 5 of the antenna 4, the antenna 4 becomes slidable with respect to the through hole 22, and the antenna 4 can be housed in the main body.

[0012]

According to the present invention, a through hole is provided in a ball member, and an antenna inserted in the through hole can be fixed to the ball member by a locking member. Therefore, according to the present invention, in the antenna mounting structure in which the antenna is rotatably supported via the ball member, the antenna can be housed in the main body, and it is not necessary to remove the antenna from the ball member. There is no fear of losing the antenna.
