Description

[Detailed Description of the Invention] The present invention relates to a table clock with a radio.

In conventional table clocks, the movement is sealed between a front frame and a rear frame, and a battery holder is integrally extended from the front frame, and the battery holder is in an open state.
This movement was then installed inside the watch case, and the battery was replaced by attaching a small battery cover to the back of the watch case. For this reason, installation of the front frame and rear frame, installation of radio speakers, etc. were all done individually, which required a lot of space, took time to assemble, and added external force to the main body. In this case, the battery holder, which receives the most impact, is unprotected as described above, so it has a disadvantage of being weak in strength.

In the present invention, the battery holding plate is a separate part from the frame body, and when the battery holding plate is attached to the front frame, a connecting part is provided to sandwich the radio speaker collar between the front frame and the battery holding plate. The structure has a connecting part between the plate and the front frame and the rear frame, and the purpose is to improve the strength of attaching the battery holding plate and also to improve the ease of assembly by also attaching the speaker and the rear frame. It is.

An embodiment of the present invention will be described.

On the front side of the body frame of the table clock shown in the first figure, a time display section 2 is arranged approximately in the right half of the front frame 1a, and a radio speaker 4 is installed inside a sound emitting hole 3 bored in the middle part. A variable capacitor knob 5 and a volume knob 6 are disposed on the left side, and a radio board 7 is disposed inside. A light section 8 is disposed at the left end so as to emit light to the left. On the back side of the body frame of the table clock shown in the second figure, a storage chamber 9 for a clock movement is provided in the left part of the rear frame 1b, and is covered with a lid 10. A heat dissipation slit 11 is provided in the upper part of the right part, and a storage chamber 13 for batteries 12 is provided in the lower part, and a part of the opening 13a of this storage chamber is covered with a small battery cover 14. 15 is a stop button, and 16 is a carrying handle. Also 17
18 is a light switch, and 18 is a radio switch.

As shown in the third figure, the battery storage chamber 13 is formed by fixing a battery holding plate 19 to the bottom of the main body frame. The battery holding plate 19 has an L-shaped cross section with arcuate corners, and is shaped to cover approximately half the circumference of the battery. In order to attach this to the main body frame, the third
~5 Connecting parts 20, 21, 22, 23 as shown
is provided.

The connecting portion 20 is connected to the battery holding plate 1 as shown in the third diagram.
9 and the front frame 1a. That is, a connecting pipe 24a is drilled rearward from the front frame 1a, and the battery holding plate 19 has a pipe portion 25a that fits around the outer periphery of this connecting pipe, and a wall surface 25b that is in contact with the rear end surface of this connecting pipe. and a connecting hole 25 in this wall that communicates with the hole of the connecting pipe.
c is formed. Therefore, the pipe portion 25a
The connecting portion 20 is constructed by fitting the connecting pipe 24a into the connecting pipe 24a and screwing the screw 26a into the hole of the connecting pipe 24a from the connecting hole 25c.

As shown in the third and fourth figures, the connecting portion 21 connects the battery holding plate 19 and the rear frame 1b.
That is, the support plates 19a and 19b are attached to the battery holding plate 19.
A connecting pipe 27 supported by the connecting pipe 27 is provided in the rear frame 1b, and a wall surface 28a facing the rear end surface of the connecting pipe and a connecting hole 28b communicating with the hole of the connecting pipe 27 are formed in this wall surface. There is. Therefore, the connecting portion 21 is constructed by screwing the screw 29 into the hole of the connecting pipe 27 from the connecting hole 28b.

The connecting portion 22 is connected to the battery holding plate 1 as shown in the fourth diagram.
9 and the front frame 1a, and also holds the radio speaker 4. That is, a connecting pipe 24b is provided rearwardly protruding from the front frame 1a, and the battery holding plate 19 has a wall surface 30a opposite to the rear end surface of the connecting pipe, and a connecting pipe that communicates with the hole of the connecting pipe 24b on this wall surface. A hole 30b is formed. An elastic speaker holding cylinder 31 is fitted into the connecting pipe 24b. This cylindrical body is made of an elastic material such as rubber, and has V grooves 31 on both end faces.
A is provided. The front end surface of the cylinder 31 is the speaker 4
Because of this, the speaker is held between the back surface of the front frame 1a and the front end surface of the elastic speaker holding cylinder 31.
Further, a radio board 7 is interposed between the connecting pipe 24b and the wall surface 30a, and the screw 26b is passed through the radio board 7 from the connecting hole 30b to connect the connecting pipe 24b.
The connecting portion 22 is constructed by screwing into the hole 4b. The presence of the V-groove 31a increases the elasticity of the cylindrical body 31, making it possible to hold the speaker more reliably.

The connecting portion 23 is connected to the battery holding plate 1 as shown in the fifth figure.
9 and the front frame 1a, and also holds the radio board 7 between them. That is, the front frame 1a
A connecting pipe 24c is provided to protrude rearward from the battery holding plate 19, and a wall surface 32a facing the rear end surface of this connecting pipe and a connecting hole 32b connected to the hole of the connecting pipe 24c are provided in this wall surface. It has been formed. The radio board 7 is connected to the pipe 24c and the wall surface 3
2a, and screwing the screw 26c from the connecting hole 32b through the radio board 7 into the hole of the connecting pipe 24c, thereby forming the connecting portion 23.

With this configuration, the three screws 26
When the battery holding plate 19 is attached to the front frame 1a using the parts a, 26b, and 26c, the collar 4a of the speaker 4 is simultaneously held between the back surface of the front frame 1a and the elastic speaker holding cylinder 31, and the radio board 7 is also sandwiched between the connecting pipes 24b, 24c and the wall surfaces 30a, 32a, thereby providing a strong connection. Then, the rear frame 1b is connected to the battery holding plate 19 by the screws 29, so that the battery holding plate is firmly fixed from the front and back. From the opening 13a to the battery 12...
... is inserted into the battery storage chamber 13 surrounded by the battery holding plate 19 and the rear frame 1b, and sealed with the battery small lid 14.

As described above, according to the present invention, the mounting strength of the battery holding plate is increased, and the battery holding plate can sufficiently withstand even if it receives a large impact from an external force. Furthermore, since the speaker holding plate and the rear frame are attached simultaneously by attaching the battery holding plate, assembly is simplified and work efficiency is improved.
