Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a switch operation control mechanism for a one-piece telephone.

[Conventional technology]

Recently, one-piece telephones have been provided which are extremely compact and convenient to carry. That is, this one-piece telephone consists of a telephone main body having an external shape that is almost the same as the handset and receiver of a general telephone, and a stand on which the telephone main body is usually placed. The telephone main body has a transmitter and a receiver built into each side thereof, and a hook mechanism, a dial mechanism, a communication circuit network, a control circuit network, etc. are built into the grip portion. Therefore, when using the telephone, the main body of the telephone is picked up from the stand and used for dialing or making a call, just like a regular telephone.

[Problem that the invention attempts to solve]

Incidentally, such one-piece telephones are often carried around, and therefore may not be used together with a stand. However, in conventional telephones of this kind, the hook button that controls the opening and closing of the hook switch is operated by an actuator provided on the stand, so it is necessary to return the telephone body to the stand after the call ends, and it must be carried far away. When the device is carried and used, it has the disadvantage that it is troublesome to carry it back to the place where the stand is installed.

Therefore, in order to solve such problems, there is a demand for the development of a one-piece telephone that can be used even when not used as a set with a stand. In that case, it would be a good idea to install an appropriate switch control mechanism on the telephone body, operate the hook button in place of the actuator on the stand, and control the opening and closing of the switch, but if you carry it around and use it, In some cases, the hook button may be returned to the stand while still being operated by the switch control mechanism. In such a case, the hook button may not be activated depending on the operating part of the stand, so even if the phone is picked up from the stand when receiving or dialing, the phone will not be able to make a call, leading the user to believe that the phone is malfunctioning. There was a problem.

Therefore, the present invention solves the above-mentioned drawbacks and makes it possible to operate the hook button and control opening and closing of the switch even when the telephone body is not used together with the stand, and moreover, the hook button remains locked in the operating position. To provide a lock switch operation control mechanism for a one-piece telephone that allows you to see at a glance that the hook button is in the locked state based on the posture of the telephone body when the telephone body is returned to the stand.

[Means for solving problems]

In order to achieve the above object, the present invention provides a one-piece telephone consisting of a telephone body and a stand.The telephone body has a hook button for controlling the opening and closing of the hook switch, and a switching knob that can be switched between two positions by external operation. , and an operating lever that operates the hook button by being rotated by the switching knob, and in a first position of the switching knob, the hook button is operated by an operating part provided on the stand, and a second operating lever is provided. In the position, the hook button is held in the operating position by rotating the operating lever in conjunction with the switching knob, and when the switching knob is in the first position, the hook button corresponds to the operating part of the knob. Instead, a switch forgetting preventing part is provided which tilts the telephone main body in correspondence with the operating part when it is in the second position.

[Effect]

In this invention, when the switching knob is switched, the hook button is activated without using the stand.
The hook switch can be held closed, and by returning the switching knob to its original position, the hook button can be released and the hook switch can be opened. Further, when the telephone body is returned to the stand with the hook button locked in the operating position, the forget-to-switch prevention section tilts the telephone body.

Next, the operation of the switch operation control mechanism 12 having such a configuration will be explained.

First, during normal use when the telephone main body 1 is used together with the stand 2, the switching knob 14 is set in advance to the solid line position in FIG. 1 (first position), and the telephone main body 1 is taken up from the stand 2. In this case, the hook button 13 is held in the position shown by the solid line in FIG. At this time, the letter "ON" displayed on the surface of the knob 14 indicates the knob mounting hole 4 as shown in FIG.
5 and will be visible. Further, the switching knob 14 is prevented from moving to the left because the position setting projection 44 is located to the right of the knob locking projection 63 of the lever receiver 25 in FIG.

In this state, the hook switch 9 is released from the actuator 29 of the hook button 13,
The telephone main body 1 is held in a talking state. When the phone body 1 is returned to the stand 2 after the call ends, the hook button 13 hits the actuating part 20 of the stand 2 and is pushed up, so the actuator 29 rotates the actuating piece 9A against the spring 36, and this When the switch 9 is closed, the telephone line is returned to the disconnected state. At this time, the operating lever 24
is rotated clockwise in FIG. 1 against the coil spring 52 by the upward movement of the hook button 13. Here, since the protrusion 21 of the mounting base 2 is provided corresponding to the left half of the knob attachment hole 45 as shown in FIG. 1, when the switching knob 14 is in the first switching position, the operation 40, but fits into the knob mounting hole 45. Therefore, the telephone body 1 is stably placed on the stand 2.

Next, if you do not use the stand 2 and want to place it in an appropriate place such as a desk, stand, shelf, etc., move the switching knob 14 to the left in Figure 1 in advance to the position shown by the two-dot chain line (second dotted line). position). Switching knob 1
4 to the left, the position setting projection 44 pushes up the knob locking projection 63, and as the projection 63 moves to the left, the switching knob 14 is held at the second position. In addition, the arm 6 of the lever receiver 25
1, when the protrusion 63 passes over the protrusion 44, it is elastically deformed upward in FIG. 1, giving a feeling of relaxation to the hand. When the switching knob 14 is switched to the second position, the lever pressing portion 43 presses the contact portion 24D of the operating lever 24 to the left in FIG. Rotating clockwise, the button drive section 24C pulls the hook button 13 into the button mounting hole 32 to the position shown by the two-dot chain line in FIG. Then, the actuator 29 of the hook button 13 engages the actuating piece 9 of the hook switch 9.
A is pressed and rotated against the spring 36 to close the switch 9. Therefore, the result is the same state as if the telephone body 1 were placed on the stand 2. In this state, if you receive an incoming call and wish to make an outgoing call, simply return the switching knob 14 to the first position shown by the solid line in FIG. Then, the actuating lever 24 is rotated counterclockwise in FIG. 1 by the force of the coil spring 52 to move the hook button 13 downward in FIG. becomes. After the call is over, switch the switching knob 14 again to the second position shown by the two-dot chain line in FIG.
is moved upward in FIG. 1 and the switch 9 is closed, thereby returning to the disconnected state. Therefore,
There is no need to take the trouble to return the telephone body 1 to the stand 2.

That is, when the stand 2 is not used, the switching knob 14 and the operating lever 24 are connected to the actuating part 2 of the stand 2.
It functions as 0.

Here, it is also conceivable to return the switching knob 14 to the second switching position after the call and return the telephone main body 1 to the stand 2. In that case, the actuating part 20 of the stand 2 enters into the button mounting hole 32 as shown in FIG. The telephone main body 1 is held in an inclined state in order to prevent the entry of the telephone. Therefore, the stability of the telephone main body 1 is poor and the user can be made aware of forgetting to switch the switching knob 14 when used together with the stand 2.

In the above embodiment, the protrusion 21 was provided on the stand 2 as a forgetting switch prevention part, but the present invention is not limited to this, and the concave part constitutes a forgetting switch prevention part, and the operation part 40 of the switch knob 14 is not limited to this. may be made to protrude from the knob attachment hole 45, and the protrusion may enter the recess when the knob 14 is in the first position.

[Effect of idea]

As explained above, according to the one-piece telephone switch operation control mechanism according to the present invention,
Not only can it be used as a set with a stand as before, but it can also be used to switch between call and disconnection states without having to return it to the stand, so it can be used when carried far away from the stand. In addition, there is no need to return the phone to the place where the stand is installed, and you can return the phone to the stand with the hook button locked in the operating position.
Since the forget-to-switch prevention section touches the operating section of the switch knob and tilts the telephone body, it is possible to notice if the user forgets to switch the switch knob, which is extremely convenient for handling.
