Description

[Detailed Description of the Invention] (Technical Field of the Invention) The present invention relates to a mounting structure for a hook button of a telephone.

(Prior art and its problems) The conventional hook button mounting structure is limited to either a tabletop or wall-mounted structure, or a special hook switch that can be used for both a tabletop and wall-mounting as shown in Fig. 1 is used, that is, a handset (not shown) is used. , the hook lever 14 of the hook switch 14 is attached to the bottom plate 13 when the hook button 11-1 is pressed when it is placed on the handset receiver 11-3 shown by the downward diagonal line to the right attached to the case 11 shown by the downward diagonal line to the left. −
By configuring 1 to operate in the direction of arrow a when mounted on a table and in the direction of arrow b when mounted on a wall, it can be used for both the table-top type shown by the solid line and the wall-mounted type shown by the two-dot chain line. was realized. In the case of a table-top type, the bottom plate 13 is arranged horizontally as shown in the figure, and in the case of a wall-mounted type, the bottom plate 13 is arranged vertically and is used by being attached to a vertical wall or the like. The structure of such a special switch is complicated and expensive, thereby increasing the product price. However, if you compare the cases where it is used as a desk phone and the case where it is used as a wall-mounted phone, there are currently very few cases where it is used as a wall-mounted phone. Even if the structure is made more complicated so that it can be used both as a tabletop type and a wall-mounted type, there are few benefits commensurate with that.

(Purpose of the invention) In order to solve the above-mentioned drawbacks of the conventional technology, the present invention eliminates the use of a special hook switch and instead utilizes the hook switch of a desk-top or wall-mounted telephone as is, by changing the structure of the hook button. To provide a hook button mounting structure that has a simple and economical structure and can be used both on a tabletop and as a wall-mount.

(Structure and operation of the idea) The present invention will be explained in detail below with reference to the drawings.

(Embodiment) FIG. 2 shows an embodiment of the present invention, in which 2-1 is a hook button, 2-1-1a and 2-1-1b are contact parts that come into contact with a hook lever 4-1 to be described later, and 2-1 -2
a, 2-1-2b is a passive end that receives gravity in direction A or B from a handset (not shown) when on-hook;
4-1 is a hook switch 4 attached to the bottom 3
The foot lever (converter) 4-1-1 is the working end that acts on the contact strip 4-3, which will be described later, and 2-3 is the feeder attached to the case 1 (not shown) as shown in Figure 1. Handset receiver, 2-4 is hook button 2
-1 is a hook button guide that guides sliding along the direction of arrow C; 4-2 is a hook lever 4-
1 is a converter shaft to which it is attached, 4-3 is a contact bullet, and 4-4 is a recovery spring for restoring the hook lever to the position shown in the figure when the handset is taken off the hook. The solid line shows the case of the tabletop type, and the imaginary double-dashed line shows the case where the handset receiver 2-3, in which the hook button 2-1 is incorporated, is rotated 180 degrees around the C direction as in Fig. 1. The case where it is wall-mounted is shown. Therefore, in the case of a wall-mounted type, the contact portion 2-1-1b of the hook button 2-1 comes into contact with the hook lever 4-1. The hook button 2-1 is adapted to slide in the direction of arrow C, which is at an angle of 45 degrees with respect to the lowering of the handset (not shown) in the direction of arrows A or B. Therefore, the amount of sliding of the hook button 2-1 is √2 times the amount of descent of the handset during on-hook, but the amount of sliding of the hook button 2-1 is
The surface where the contact part 4-1a and the contact part 2-1-1a of -1 are in contact is in the direction A of application of actuation force by the handset.
Since both B and B are perpendicular to the A direction and α = 45°, the ratio of the amount of sliding and the amount of descent becomes 1:1, so the descent of the foot lever 4-1 due to the slope descent is the same as before. Function can be maintained. Furthermore α>
If the angle is set to 45 degrees, the above ratio will be less than 1, allowing the use of a hook switch with a large operating load. On the other hand, if a hook switch with light load operation is used and the protrusion height of the hook button is desired to be low, it is sufficient to set α<45°.

As described above, in the present invention, the hook button guide 2-1 is configured so that the hook button 2-1 can slide in the direction C that roughly bisects the angle between the two operating force application directions A and B that form approximately 90 degrees. 4 is set, and the center of the upper end surface of the hook button 2-1 and both edges 2-1-2a and 2-1-2b as seen from 2-1-3 are opposite to each other in the two operating force application directions A and B. It is configured to be an actuating force passive end. By sliding the hook button 2-1 in the direction of arrow C, both edges of the lowermost end surface facing the center 2-1-4 of the hook button, which is the passive end in this case, are opposite to the upper edge 2-1-2a. The contact portion 2-1-1a of the lever 4
-1 and becomes the contact end, so the foot lever 4-
1 rotates in the direction of arrow _D1 around the converter shaft 4-2, and operates the contact strip 4-3 by means of the working end 4-1-1. When the actuation force is removed, the recovery spring 4-
4, the hook lever 4-1 rotates in the direction of arrow _D2 about the converter shaft 4-2, thereby also restoring the hook button 2-1.

If it is attached as shown in the solid line, it will be used as a tabletop type, but if the handset receiver 2-3 is made to be replaceable with case 1 (not shown) and attached as shown in the imaginary line, the bottom plate 3 can be used. It is a wall-mounted type that can be attached to a wall. In the case of this wall-mounted type, the handset receiver 2-3 and the hook button 2-1 are removed from the case 1 while still being formed integrally, and the whole is rotated 180 degrees with the direction of arrow C as the axis of rotation as shown by the two-dot chain line. When rotated, the two contact parts 2-1-1a, 2-
Vertical relationship of 1-1b and two passive ends 2-1-2
The vertical relationship of a and 2-1-2b is switched.

In this way, mutual changes between tabletop type and wall-mounted type,
In order to remove the hook button 2-1 from the handset receiver 2-3, as shown in FIG. -1-1a, 2-1-1b are 2
Some locations are required.

(Effects of the invention) As explained in detail above, the present invention allows the sliding direction of the hook button to be approximately 45 degrees with respect to the operating direction of the hook button. It can be hung on the wall and has great economical effects.
