Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a telephone switch capable of making on-hook calls.

When you take off the handset (turn it off-hook), the hook button operates, and this on-hook switches the shift switch to the operating state, allowing you to make calls using the handset.Furthermore, operating the function button switches the multi-function switch to the operating state. Telephones that can be switched to place the built-in speaker in a listening state and then make a telephone hook call are well known.

By the way, with conventional telephones of this type, after confirming the response from the other party through the speaker by making an on-knock call, in order to pick up the handset and talk to the other party, the user must lift the handset (go off-hook) and further. There was the trouble of having to return the function switch to a non-operating state by operating the function button. Therefore, it is possible to create some kind of interlocking relationship between the hook button and the function switch, so that when the handset is picked up, the hook will be linked to the tongue movement, and the function switch will automatically return to the non-operating state. However, if only an interlocking relationship were provided, there was a risk that the function switch would automatically return to its original state before the hook switch was switched to the operating state due to the off-hook operation, and the line would be disconnected. In order to prevent such problems from occurring, a complicated interlocking mechanism is required to ensure that the hook switch switches to the operating state and then returns the function switch, and the entire switch device has a complicated configuration. I didn't expect it to be that long.

The present invention has been made based on the above circumstances, and its purpose is to link the hook button and the function switch via a simple interlocking member in a telephone equipped with a switch capable of making an on-hook call, so that an on-hook call can be made immediately after the on-hook call is made. The purpose is to enable handset calls to be made.

The configuration of the present invention will be explained below based on embodiments shown in the drawings.

Fig. 1 shows the schematic structure inside the main body of the telephone, in which a board 1 and an i4 channel 2 are integrated via studs 3, and between the board 1 and panel 2 there is a hook switch 4, a function switch. 5, hook button 6, function button 7, etc. are arranged. The hook tongue 6 has one end pivotally supported on the inner surface of the tongue 2 so as to be movable up and down, and the function button 7 is attached to the upper end of a movable member 8 provided so as to be movable up and down. These buttons 6.2 extend through openings 15A and 7A provided in the armpit 2 so as to project toward the ground side of the panel 2.

The hook button 6 is designed to switch the hook switch from an operating state (hook switch ON state) to a non-operating state (hook switch OFF state) when the hook button 6 moves downward, and when the hook button 6 moves upward. When rotating to
The initial operation switches the hook switch 4 from a non-operating state to an operating state. On the other hand, the movable member 8 has a bottle 1 at its lower end.
0, and this bottle 1o is fitted into a vertically elongated hole 12 provided in a fixing member 11 so as to be able to move up and down (
(Fig. 3), it is also rotatable in the horizontal direction within the range of the open lower A using the bin 10 as a fulcrum. This movable member 8 is biased upward by a spring 13 stretched between the fixed member 11 and the bottle 10, and causes the function button 7 to protrude upward from the lower A. When the tongue 7 is pushed down against the spring 13, this rf tongue 7
When the button 7 is released, the return force of the spring 13 causes the function switch 5 to return to the non-operating state. Note that the sedge ring 13 can be omitted by making the function switch 5 have a return force.

A locking member 14 whose upper end is bent into a hook shape is attached to the upper surface of the board 1, and the locking member 1 is attached to the function button 7 of the device.
A stepped portion 7B that can be engaged with the upper end bent portion of 4 is provided. Therefore, when the function button 2 is rotated horizontally from the depressed position (from the imaginary line position to the solid line position in FIG. 3) using the bottle 1o as a fulcrum, the stepped portion 7A engages with the upper bent portion of the locking member 14. At the same time, the function prohibits the tongue 7 from rising again, and the function switch 5 is kept in the operating state.

Furthermore, an interlocking member 15 is disposed on the top side of the board 1 between the hook button 6 and the functional tongue 7. The interlocking member 15 has an intermediate portion rotatably supported on a fixed portion 16 of the base plate 1 via a shaft 17, and one end of the interlocking member 15 is located below the rotation end of the tongue 6. Also, interlocking member 1
The other end of the interlocking member 15 is close to the function button 7, and a protrusion 18 facing the other end of the interlocking member 15 is provided at the bottom of one side of the function button 7. A spring 19 is attached to the shaft 17, and the n1 interlocking member 15 is rotated counterclockwise in FIG. 1 by the elasticity of the spring 19.

Incidentally, the other end of the interlocking member 15 is formed with an upper inclined surface 20 and a lower inclined surface 2 which are inclined at a 6-degree angle.

When the telephone is in the standby state, the hook is placed on the tongue 6 due to the weight of the handset (not shown), and the hook is on the tongue 6 as shown in FIG. It is in the downward rotation position shown by the line. The exercise unit control 5 is also pressed by the hook button 6 and held in the rotating position shown by the imaginary line in the figure.

An on-hook call is made by pressing down the function button 7 and switching the function switch 5 to the operating state.
When the tongue 7 is engaged with the locking member 14, the function is such that the protrusion 18 of the tongue 7 is located below the lower inclined surface 21 of the interlocking member 15, and furthermore, these protrusions 18 and the lower inclined surface 2
A gap fG in the vertical direction exists between the When the hook button 6 is rotated from the imaginary line position to the solid line position in FIG. 1, the interlocking member 15 is also rotated counterclockwise by the elasticity of the spring 19, The inclined surface 21 is brought closer to the protrusion 18 of the function button 7, but due to the initial operation of the hook button 6, the downward slope of the interlocking member 15 is first changed after the hook switch 4 is switched from the non-operating state to the operating state. Side 2
1 is still in contact with the protrusion 18. Then, in conjunction with the later operation (later operation) of the hook button 6, the lower inclined surface 21 of the interlocking part @ZS comes into sliding contact with the protrusion 18, and the function is to remove the tongue 7 from the locking member 14.

In addition, in this off-hook state, that is, in a state in which the handset is removed, the hook button 6 and the interlocking member 15 are in the solid line position in FIG.
When the button is engaged with the locking member 14, the function is activated by the protrusion 18 of the tongue 7.
comes into almost contact with the upper inclined surface 20 of the interlocking member 15 (see FIG. 3).

Therefore, when you pick up the handset set from the standby state of this telephone, the hook and tongue 6 rotate upward due to the elasticity of the spring 4, the hook switch 4 switches to the operating state, and the line is connected, allowing you to make calls (handset) and make calls. It becomes possible. That's a shame, when you put down the handset it goes into standby mode.

Next, when the function button 7 is pushed in from the standby state and horizontally rotated to engage the locking member 14, the function switch 5 is held in the operating state and the speaker provided inside the telephone body is placed in the receiving state. , and the line is connected, allowing on-hook calls. In addition, when you pick up the handset after confirming the response from the other party through the speaker by making an on-hook call, the hook button 6 rotates upward, but as described above, the hook switch 4 is first activated by the initial operation of the hook and +f buttons. After switching, the interlocking part 15 raises the function button 7 due to the late operation of the hook button 6.
As a result, the function switch 5 is switched to a non-operating state, and the handset is in a talking state.

Further, when the function button 7 is pressed again from the handset talking state, the function switch 5 is activated and the speaker is placed in a receiving state, resulting in a so-called handset loudspeaker talking state. In order to switch from the handset loudspeaker call state to the handset call state, all you have to do is turn the function button 7 horizontally, release it from the locking member 14, and set it to 9- so that it returns to the upper position. To change from the loudspeaker state to the standby state, simply turn on the handset.

That is, in the handset loudspeaker call state, the interlocking member 15
The button 7 is located at the solid line position in FIG.
Since it is almost in contact with the upper inclined surface 20, when the handset is placed, the hook button 6 rotates downward and the hook switch 4 becomes inactive, and at the same time, the hook button 6
Due to the rotation of the interlocking member 15 in conjunction with the rotation of the interlocking member 15, the sloped surface 20 comes into sliding contact with the protrusion 18, and the tongue 7 is returned to its original state, whereby the function switch 5 is also brought into a non-operating state.

As described above based on the embodiments, the telephone switch device according to the present invention is provided with an interlocking member that interlocks with the operation of the hook button when the handset goes off-hook, so that the initial operation of the hook and the TP methane does not cause seama. After switching the hook switch to the operating state, the interlocking part will switch the function switch to the inactive state due to the later operation of the hook button.
10-, so after confirming the response from the other party through the speaker when making an on-hook call, you can switch to a handset call by simply picking up the handset. Since the function switch becomes inactive after the switch is activated, there is no risk of the line being disconnected when switching from on-hook to handset calls; The above effects can be achieved.

Note that the present invention is not necessarily limited to the configurations of the embodiments, and can be implemented with various modifications. for example,
A gap is provided between the hook tongue and the interlocking member, so that when the hook button operates, the hook button first switches the hook switch to the operating state, and then the hook two tongue and the interlocking member have an interlocking relationship. You can also do this.
