Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a foot lever mounting structure particularly suitable for use in a desk/wall-mounted telephone.

In general, what are known as in-house telephones can be roughly divided into two types based on their usage: desktop type and wall-mounted type, and each type has been known in various structures. In recent years, there has been a strong demand for a combination of these, ie, a dual-purpose telephone that can be used both on a desk and on a wall, and for this reason, various research and developments are underway.

By the way, the challenges in producing such a desk/wall-mounted phone are to simplify the overall configuration, improve the ease of processing and assembling each part, and to make the entire device smaller and more compact. The exterior has a simple design, is easy to operate, and can be used as a tabletop or wall-mounted device by replacing the minimum number of parts and simple work. This is what is required.

One of the problems in meeting these demands is the mounting structure of the foot lever that opens and closes the foot switch in accordance with the raising and lowering of the handset. In other words, the foot lever is fitted into a long groove-shaped opening formed in the handset receiving portion of the telephone housing, and is supported in a swingable manner by pivoting one end of the foot lever. Generally, a structure is adopted in which the above-mentioned foot lever is attached from the back side of the case and supported pivotably, and this has resulted in the problem that the attachment work is troublesome. Furthermore, since a foot switch and the like are also installed on the back side of such a foot lever, it is troublesome to exchange the one for tabletop use and the one for wall hanging. In particular, when changing the usage status of this type of dual-purpose telephone from a tabletop type to a wall-mounted type or from a wall-mounted type to a tabletop type according to the user's request, an inexperienced staff member would be unfavorable in terms of work efficiency. If the user were to make such changes directly, there was a risk that unnecessary parts would be removed, making the telephone unusable.

In addition, in the above-mentioned foot lever mounting structure,
When assembling a telephone, it is necessary to assemble the foot switch and the like beforehand, and this poses a problem in that the foot lever may get in the way or be damaged during subsequent work. Particularly, in wall-mounted hook switches, the claw portion for hooking the transmitter and receiver projects outward, and this protruding portion causes the above-mentioned problems, so it is desired that some kind of countermeasure be taken.

The present invention has been made in view of the above circumstances, and includes a shaft portion protruding from the inner surface near one end of the opening on the housing side, which serves as a pivot point for the foot lever, and a shaft portion that is engaged with the shaft portion. A pair of long grooves each having one end opened at both sides of the foot lever are provided on both side plates of the foot lever, and at the other end of the foot lever, a pair of long grooves protruding outward from the side edge portions of the flexible side plates respectively are secured to the inner edge of the opening. Provided is a foot lever mounting structure for a telephone that skillfully utilizes the elastic deformation of the foot lever to allow the foot lever to be easily and appropriately attached and detached from the outside of the casing by having a simple structure in which a pair of protruding locking protrusions are provided. It is something to do.

Hereinafter, the present invention will be explained in detail using embodiments shown in the drawings.

FIGS. 1 and 2 show an embodiment of a desk-wall-mountable telephone to which the present invention is applied. In these figures, the desk-wall-mountable telephone, designated as a whole by reference numeral 1, is made entirely of synthetic resin. It has a telephone housing 2 formed in a substantially box shape from material, and this housing 2
The housing 3 is composed of a lower housing 3 having an upward opening and an inclined bottom plate 3a, and an upper housing 4 joined to cover the opening.
The reason for slanting the bottom plate 3a of the lower casing 3 mentioned above is that, as shown in FIG. On the other hand, when this telephone 1 is used as a wall-mounted device, the lower side of the telephone 1 protrudes from the wall surface (not shown) to the front side compared to the upper side, as shown by reference numeral 5 in FIG. It is advantageous to use a mounting bracket constructed in this way. Here, the bottom plate 3a of the lower housing 3 is suitably provided with a locking hole 3b into which the hook 5a on the mounting bracket 5 side is locked.

Further, on the left side of the front panel surface 4a of the upper housing 4, as shown in FIG. A handset accommodating portion 8 is formed which includes a mouthpiece receiving portion 8a and a mouthpiece receiving portion 8b that accommodate and hold the portion 7a and the mouthpiece portion 7b. On the other hand, on the right side of the front panel surface 4a, there is provided an operation section 9 in which various operation buttons such as a push button type dial mechanism 9a and a push button for switching extensions are arranged, and a printed wiring having a corresponding switch. In addition to the board, the telephone circuit network, magnetic bell, and switch mechanism necessary for the telephone are arranged within the housing 2. Furthermore, the telephone 1 in this embodiment is configured such that a speaker section 8c is provided in the handset accommodating section 8 so that the other party can hear what the other party is saying without having to pick up the handset 7, and also has a built-in microphone, etc. (not shown). .

Now, according to the present invention, in the telephone 1 having the above-described configuration, the earpiece receiver 8 of the handset accommodating section 8
The foot lever 10, which is swingably supported within the housing 2, is configured to be attachable and detachable from the outside of the housing 2, thereby making it possible to easily and appropriately replace the foot lever 10 (10A, 10B) and assemble the foot lever 10 (10A, 10B). It is characterized by the fact that it can be carried out.

To explain this in detail with reference to FIGS. 3 to 7, in a portion of the upper housing 4 corresponding to the earpiece receiver 8a, there is an opening 11 having a long groove shape toward the mouthpiece receiver 8b. A pair of support pieces 1 are provided on the inner edge of the upper end of the opening 11 and protrude toward the back side of the housing 4.
2 and 12 are provided. At the tips of these support pieces 12, 12, a pair of boss portions 12a, which form a shaft portion serving as a rotational fulcrum of the foot lever 10, are provided.
12a are protrudingly provided to face each other. Furthermore, as shown in FIG. 7, the inner edge of the opening 11 near the lower end is formed with notch steps 13, 13 that open at the opening edge, and the inner edge of the lower end is provided with a rotation amount of the foot lever 10. A pair of locking pieces 14, 14 having claw portions 14a, 14a that restrict the movement of the housing 4 at a predetermined interval from the inner surface of the housing 4 are provided. In addition, the seventh
The L-shaped pieces indicated by reference numerals 15 and 15 in the figure are for guiding the lower end of the foot lever 10 toward the opening 11 when the foot lever 10 is installed from the back side of the housing (described later).

On the other hand, the foot lever 10 is shown in FIGS.
As is clear from the figure, it is formed of a synthetic resin material and has a substantially U-shaped cross section, and has a tabletop hook lever 10A with a flat surface and a hook 10a on which the transmitter/receiver 7 is hooked on the lower end of the surface.
A wall-mounted foot lever 10B having a wall-mounting lever 10B is prepared. These two foot levers 10 (10A, 10B) have a pair of long grooves 16, 1 formed in both upper end side plates with one end open.
6, and is configured to be pivotally supported by inserting these long grooves 16, 16 into the opening 11 and engaging the boss portions 12a, 12a. Also, this foot lever 10 (10A, 10
As shown in FIG. 4, the openings 11 are provided at the side edges of both side plates on the lower end side of B), each projecting outward.
A pair of locking protrusions 17, 17 are integrally formed to be locked in notch steps 13, 13 formed on the inner edge of the cover, thereby preventing the cover from coming off during installation. Lower end portions 17a, 17a of these locking protrusions 17, 17 protrude to face each other, and function as a retainer for a spacer to be described later. Two pairs of guide walls 17b for guiding spacers, which will be described later, are provided on the inner surfaces of both side plates below these locking protrusions 17, 17, facing each other.

In such a configuration, the foot lever 10 (10A, 10B) is inserted into the opening 11 from the outside of the telephone housing 2, and the long grooves 16, 16 at the tip thereof are inserted into the boss portion 12, as shown in FIG.
a, 12a, and further locking protrusions 17, 1
7 part is pressed from both sides to elastically deform the opening 1.
It is easy to understand that it can be easily and reliably attached by fitting it into 1, and that it can also be easily removed.

Therefore, with such a mounting groove structure for the foot lever, the foot lever 10 can be assembled to the phone housing 2 at the final stage when assembling the phone 1, which not only simplifies the overall assembly work. This has the advantage that, after assembly, it is possible to easily and reliably exchange between a tabletop version and a wall-mounted version.

In addition, 18 in the figure is the foot lever 10 (10A,
10B), which extends from the edge of one side plate toward the inside of the casing 2;
As shown in the figure and FIGS. 6a and 6b, the foot lever 10 is engaged with the stepped portion of the foot switch lever 19a of the foot switch 19 disposed in the housing 2 opposite to the foot lever 10, and the foot lever 10 is opened at its lower end. 1
1. This is to hold it so that it does not come into contact with the inner surface. That is, in the above-mentioned foot lever mounting structure, the foot lever 10 has long grooves 16, 16.
Since the lever 10 is supported by engaging the boss portions 12a, 12a on the side of the housing 2, the foot lever 10 moves in its longitudinal direction and comes into contact with the inner edge of the opening 11. However, when the foot lever 10 swings as the transmitter/receiver 7 is raised or lowered, a slight problem arises in terms of smoothness. Therefore, in this embodiment, in order to solve this problem, the above-mentioned hook switch lever 1 is used.
9a is skillfully utilized to enable smooth and appropriate rocking motion.

In addition, the above-mentioned foot lever 10 (10A, 1
0B), the switch 19 is activated when the handset 7 is picked up, as shown in FIGS. 5 and 6 a and b.
The spring 19b urges the outside of the housing 2 via the hook switch lever 19a, and as a result, the hook switch 19 is closed and a call signal is sent out. On the other hand, when the handset/receiver 7 is placed on or hooked up, it rotates inward against the above-mentioned spring 19b, thereby opening the hook switch 19 and stopping signal transmission. Note that 7c in the figure is a hook hole formed in the neck of the earpiece portion 7a of the handset 7, which is hooked to the hook 10a of the wall hook lever 10B.

By the way, in the foot lever mounting structure having the above-mentioned configuration, since the foot lever 10 can be attached and detached from the outside of the casing, workability during assembly can be improved, but on the other hand, there is a risk that the foot lever 10 may be removed by mischief such as a child. This may cause problems such as damage or loss of the foot lever 10. If such a problem occurs, a spacer indicated by the reference numeral 20 in FIG.
It is only necessary to use b as a guide and insert it inside the foot lever 10 at a portion located between the locking protrusions 17, 17, so as to restrict the above-mentioned elastic deformation. At this time, the interposed spacer 20 is prevented from coming off by the lower end portions 17a, 17a of the locking protrusions 17,17. Such a spacer 20 may be detachably attached to the foot lever 10 as in this embodiment, or may be prepared as an integral part of the foot lever 10 in advance, and may be selected as appropriate. It is.

The foot lever 10 provided with the spacer 20 is installed from the back side of the housing 4, as shown in FIG.
into the boss portions 12a, 12a, place the other end on the claw portions 14a, 14a of the locking pieces 14, 14, and in this state push in the foot lever 10 using the guide pieces 15, 15 to lock it. piece 14, 14
It is good to deform elastically. When such a configuration is used, the foot lever 10 is rotatably supported by the locking pieces 14, 14 within the allowable range, and cannot be attached or detached from the outside of the casing, thereby reliably preventing tampering. Can be done.

In addition, according to the dual-purpose telephone 1 shown in this embodiment, the structure of each part is simplified, processing and assembly are improved, the overall size and compactness are achieved, and furthermore, easy operation allows for desk-top and wall-mounting. Care has been taken to allow changes to be made.

That is, in the telephone 1 according to the present embodiment, the earpiece receiver 8a of the handset accommodating section 8 is connected to the housing 2.
It is formed by cutting upwards. This is to prevent it from getting in the way of raising and lowering the handset 7 when the telephone 1 is used as a wall-hanger. However, when such a cutout portion is used for tabletop use, it is easy to cause the handset/receiver 7 to hang half-hung, and some countermeasure is required.

Therefore, according to this embodiment, the side edge of the lower housing 3 corresponding to the cutout part of the earpiece receiver 8a of the upper housing 4 is provided with the shape shown in FIGS. A protrusion 21 having a substantially triangular cross section for preventing half-hanging is detachably provided at the top. If such a protrusion 21 for preventing half-hanging is used, even if the handset 7 is placed in a half-hung state as shown by the imaginary line in FIG. 5, the handset 7 will move in the direction of arrow A in the figure due to its own weight. However, the earpiece portion 7a is guided into the earpiece receiver 8a on the housing side, thereby eliminating the half-hung state.

When used as a wall hanging device, the protrusion 21 for preventing half-hanging is removed, and the handset rest 22 having the hook portion 22a is attached to the right end thereof, as is clear from FIGS. 6a and 6b and FIG. 8. It's a good thing. This hand set rest 2
When used as a wall-mounted telephone, 2 is a place on which the handset is hung in order to temporarily leave the telephone during a call, and is necessary in the case of a wall-mounted telephone.

Note that FIGS. 6a and 6b show a case where the upper housing 4 and the lower housing 3 constituting the telephone housing 2 are inverted 180 degrees and combined, and the telephone 1 in this embodiment is There are other ways to use it like this. That is, in order to use this type of dual-purpose telephone 1 as a wall-mounting device, it is common to use the mounting bracket 5 shown in FIG. In the telephone 1 according to the present embodiment, as shown in FIGS. 9a and 9b, the upper housing 4 is inverted 180 degrees and assembled to the lower housing 3, so that other parts such as the above-mentioned bracket 5 can be assembled. It is also possible to change between tabletop use and wall hanging use without the need for any. That is, by inverting the upper housing 4, the slope of the bottom plate 3a of the lower housing 3 is changed to the above-mentioned bracket 5.
It has the same function as the slope of the bottom plate of the lower case 3.
It is also possible to hang the bottom plate 3a directly on a hook provided on the wall.

In addition, when used inverted in this way, the above-mentioned half-hanging prevention protrusion 21 is attached to the lower housing 3.
It is also possible to improve processability and assemblability by forming it integrally. That is, when the upper housing 4 is inverted and used for wall hanging, a storage section 23 is provided in correspondence with the projection 21 for preventing half-hanging, as shown in FIG. 10, for storing this projection 21. There is.

Therefore, the half-hanging prevention protrusion 21 integrally formed on the lower housing 3 does not pose any problem even when the telephone 1 of this embodiment is used as a wall-hanging device. On the other hand, the hand set rest 22
As shown in FIG. 9b, it goes without saying that it is removably provided on the side edge of the lower housing 3 corresponding to the earpiece receiver 8a when it is hung on the wall.

Further, in the telephone 1 according to the present embodiment, the bottom plate 3a of the lower housing 3 has a plurality of keyholes 26 consisting of a long hole 24 and a circular hole 25 connected to the long hole 24, as shown in FIG. It is provided. These can be used in common when the upper housing 4 is inverted and used for both wall hanging and tabletop use as described above. In other words, when using it for tabletop use,
Rubber feet 27 are configured to be removably fitted into these keyholes 26, and as shown in FIG. 25a, and a portion of its tip protrudes outward to function as a rubber foot. Further, FIG. 1B shows a case where a flat mounting bracket 28 is used and the hook 28a thereof is inserted into the key hole 26 to be used for wall hanging. However, it is of course possible to directly hook it onto a hook protruding from the wall surface without using such a mounting bracket 28.

Furthermore, in the case of using the flat mounting bracket 28 as described above, by adopting the configuration shown in FIGS. The installation of the telephone 1 becomes reliable, and its removal becomes easy. That is, at the upper end of the mounting bracket 28, a bent piece 28b is provided facing the upper end surface of the telephone housing 2 at a predetermined distance.

On the other hand, the folded piece 28b is inserted into the gap between the upper corner of the phone housing 2, and the housing 2 is attached to the bracket 28.
The stator 29 to be fixed is entirely made of synthetic resin, and has a U-shaped elastic locking pawl 29a and a stepped portion 29b at one end thereof. The tip of the elastic locking pawl 29a projects higher than the stepped portion 29b, and
The length in the longitudinal direction of b is formed to be approximately the same as that of the bent piece 28b, and the thickness of the stepped portion 29b is formed to be approximately the same as the gap between the upper end surface of the housing 2 and the bent piece 28b.

Therefore, the stator 29 configured in this way
When the elastic locking pawl 29a is elastically deformed and inserted, the stepped portion 29b is connected to the upper end surface of the housing 2 and the bent piece 28b.
The housing 2 is fixed to the bracket 28 by fitting into the gap between the housing 2 and the bracket 28. Furthermore, when the housing 2 is to be removed from the bracket 28, the stator 29 may be removed while elastically deforming the elastic locking claws 29a of the stator 29 with fingers or the like.

In addition, in the telephone 1 shown in this embodiment, the pull-out part of the curl cord 6 for the handset 7 that is pulled out from the housing 2 is structured as shown in FIGS. It is also possible to withdraw it.

That is, a window 30 for drawing out the cord is provided on one side of the lower housing 3. Guide grooves 30a, 30a are provided on both sides of this window portion 30,
Further, this window portion 30 is open at the end surface where it is joined to the upper housing 4. When pulling out the curled cord 6, the cord 6 is temporarily held in the cord holding member 31, as shown in detail in FIG. Guide grooves 31a, 31 are provided on both sides of this holding member 31.
A is provided. On the other hand, reference numeral 32 in the figure denotes a fixture, which has a substantially U-shape, and has a pair of engagement protrusions 32a and 32b on both outer and inner sides thereof, respectively.

Therefore, after positioning the cord holding member 31 holding the aforementioned cord 6 in the window portion 30, the fixture 32 is inserted into the guide groove 30a with one engagement protrusion 32a.
If the window portion 30 is slid downward while engaging with the other engaging protrusion 32b, the other engaging protrusion 32b will engage with the guide groove 31a of the holding member 31, and the holding member 31 will eventually move into the window portion 3.
It will be held fixed at 0. This fixture 32 is prevented from coming off at the joint surface by covering the upper housing 4 with the lower housing 3.

On the other hand, when pulling out with a jack, a jack fixture 33 is used as shown in FIG.
This jack fixture 33 has engaging protrusions 33a, 33a on both sides, and a pair of engaging pieces 3 on the back side.
3b and 33b are provided protrudingly. Therefore, the jack is fixedly held on these engaging pieces 33b, 33b, and then the engaging protrusions 33a, 33a are engaged with the guide grooves 30a, 30a of the window part 30, thereby fixing the fixture 33 in the window. 30.

In addition, when pulling out the curl cord described above, it is temporarily fixed through the holder 31, but in order to fix the curl cord, a dovetail-shaped long hole having an opening is formed in the lower end surface of the holder 31. Of course, the holder 31 may be integrated with the fixture 32 similarly to the jack type.

In addition, in the telephone 1 according to this embodiment, as shown in FIGS. 2 and 16, a window 34 is also formed on the side surface of the lower casing 3, which is 180 degrees offset from the cord drawer window 30 described above. It is configured to serve as a cord drawer when the tabletop and wall-mounted versions are flipped 180 degrees. This window portion 34 is normally closed by a closing plate 35 having substantially the same shape as the fixture 33, and is replaced at the time of the above-mentioned change. In addition, 36 in the figure is a switch for restricting incoming calls to provide additional functions to the telephone 1. If you want to operate this switch 36, you can remove the blocking plate 35 and operate it from outside the housing 3 with a screwdriver etc. can.

Furthermore, according to this embodiment, by configuring the transmitter/receiver 7 as shown in FIGS. 17 to 19 a and b, the overall size and compactness can be achieved, and ease of assembly can be improved. It is composed of That is, this type of handset 7 is generally formed by combining an upper case 40 and a lower case 41, and has a speaker 42 inside.
and a microphone 43 are incorporated.
By the way, in such a transmitter/receiver 7, both the upper and lower cases 40, 41 are engaged by engagement means provided at both ends in the longitudinal direction, and are engaged by one or two screwed portions provided in the center. It is configured to be screwed, but in this case, space is required for the engaging means portions at both ends, which tends to increase the overall size, and the molding of each screwed portion is troublesome, and it is difficult to assemble. This has caused problems that are said to be undesirable.

Therefore, in this embodiment, the upper case 4 is attached to the end of the handset 7 on the mouthpiece side that is curved downward.
A locking protrusion 40a that protrudes inward on the 0 side and an engagement hole 41a of the lower case 41 that locks the protrusion 40a (see FIG. 18) are formed, and a locking protrusion 40a protruding inwardly on the lower case 41 side is formed at the longitudinal center of the transmitter/receiver 7. A boss portion 40b having a screw hole is protruded from the upper case 40 corresponding to the screw hole 41b, and an annular protrusion 41c surrounding the screw hole 41b is protruded from the inner surface of the lower case 41 facing the boss portion 40b. I am trying to set it up. Further, at the end on the earpiece side, a locking piece 40c having an outward claw on the upper case 40 side and a lower case 4 that locks the locking piece 40c.
A locking hole 41d on the first side is provided. In such a configuration, the upper case 40 is slid from the mouthpiece side with respect to the lower case 41, the locking projection 40a is locked in the locking hole 41a, and the boss portion 40b is inserted into the annular projection 41c. After fitting the cases 40 and 41 in the longitudinal direction, the locking piece 40c at the other end and the locking hole 41
d is engaged. With this configuration, the peripheral edge portion of the boss portion 40b on the upper case 40 side on the mouthpiece side is engaged with the annular protrusion 41c of the lower case 41 and maintained in that state.
There is an advantage that the screw holes of 0 and 41 are assembled in a correctly aligned state, and as a result, the ease of assembly is greatly improved. In addition, the ends of the upper and lower cases 40, 41 on the mouthpiece side are provided with a locking protrusion 40a and an engagement hole 41a that are slidably engaged, instead of a locking piece 40c provided on the earpiece side. Since they are engaged, the space in that part is minimized, the longitudinal length of the handset 7 can be shortened, and a small and compact handset can be obtained.
In the figure, 44 is a tightening screw for both cases 40, 41, and 40d is a hole for pulling out a cord.

In addition, when disassembling the upper and lower cases 40 and 41 forming the above-mentioned transmitter and receiver 7, after removing the screws 44, the upper and lower cases 40 and 41 are twisted along the width direction to engage with the locking piece 40c. Stop hole 41
d is disengaged, and the upper and lower cases 40, 41 can be easily disassembled.

Further, as shown in FIG. 1, the telephone 1 according to the present embodiment is provided with operation buttons 53 and 54 for various slide switches and a switch board 62 for push button switches on the operation section 9 on the front side. In this case, there are issues with dust-proofing the slide switch part and the structure of the push button that allows multiple contacts to be operated at the same time.

Therefore, according to this embodiment, as a dustproof measure for the slide switch, the steps shown in FIGS.
The configuration shown in b is adopted. That is,
When two slide switches 50 and 51 are arranged side by side so as to move in the same direction, in order to close the long holes 52a and 52b drilled on the operation panel 52, the shafts of the operation buttons 53 and 54 must be Part 53a, 5
A dustproof plate is required that has a hole into which the part 4a fits. However, simply disposing these dustproof plates on the panel 52 is not preferable in terms of operation or installation space, since the amount of movement of the plates would extend to a position where they would interfere with each other.

As a countermeasure against this, in this embodiment, two dustproof plates 55, 56 having a length that covers the elongated holes 52a, 52b of both slide switches 50, 51 are used.
and holes 55a, 56a into which the shafts 53a, 53b of the operation buttons 53, 54 fit, respectively.
and elongated holes 55b and 56b corresponding to the elongated holes 52a and 52b of the other switch are bored, and these are overlapped and supported slidably by a support piece 57 on the back surface of the panel 52. and,
According to such a configuration, each dustproof plate 55,
56 can freely slide without interfering with each other due to the presence of the elongated holes 55b and 56b, and
The elongated holes 52a and 52b of the panel 52 are reliably closed by both plates 55 and 56, so that even if two or more slide switches are disposed close to each other, reliable dustproofing can be achieved, and in a small space. They can be appropriately installed side by side with plenty of room within. In addition, both dustproof plates 55,
The sliding contact surface of 56 is textured to prevent sticking due to infiltration of moisture, etc.

Further, as a switch means for pressing a plurality of contacts at the same time, push switches 60a and 60 each having one contact are used as shown in FIG.
60c are arranged side by side on a printed circuit board 61, and are configured so that they can be pressed and operated by one switch board 62. This is because a push switch having a plurality of contact functions is expensive and the printed wiring on the printed circuit board 61 is troublesome. However, the problem with such a configuration is that the operation panel 6
When the switch board 62 exposed on the switch board 3 is pressed, if the position of the switch board 62 is shifted to one side, it is often pushed to one side, and as a result, proper switch operation cannot be expected.

Therefore, by adopting the configurations shown in FIGS. 23 and 24a and 24b, the device of this embodiment has the minimum required number of parts and a simple configuration, but it is possible to push switch 6
0a, 60b, and 60c can be pressed simultaneously. That is, the sliding parts 62a provided at both ends of the switch board 62 are located on the back side of the panel 63 at both ends of the operation hole 63a.
Holding pieces 64, 64 for holding 62a are provided protrudingly,
In addition, locking pieces 65, 65 having claw portions 65a, 65a at their tips are protrudingly provided in the vicinity thereof. On the other hand, on the back side of this panel 63, an engagement groove 66a is provided at the base of the portion corresponding to the side edge of the operation hole 63a.
A projecting piece 66 having a diameter 66a is provided in a protruding manner. A pair of hinge parts 67a, 67 are engaged in these engagement grooves 66a, 66a and are swingably supported.
A bracket member 67 having a diameter of 1.a is disposed below the switch board 62. This bracket member 67 has engagement protrusions 67a and 67b on the other side edges thereof, which are engaged by the claws 65a and 65a of the engagement pieces 65, 65, so that the bracket member 67 can be rotated within a predetermined angle range on the back surface of the panel 63. It will be installed so that it can be moved.

Therefore, when such a bracket member 67 is used, all the push switches 60a, 60b, 60 can be operated by pressing the switch board 62.
It has the advantage that it is possible to operate the C and C at the same time, has a simple structure, and is easy to process and assemble.

It goes without saying that the present invention is not limited to the structure of the embodiment described above, and that the shape, structure, etc. of each part can be modified and changed as appropriate. Furthermore, the foot lever mounting structure according to the present invention is not limited to the desk/wall-mount type telephone in the above-mentioned embodiments, but can also be applied to various types of telephones that are generally well-known. Any telephone may be used as long as it has a lug lever that is built in and swings. By applying the present invention to these telephones, the installation work of the foot lever can be carried out extremely easily and reliably, which also has the advantage of simplifying the assembly work of the entire telephone.

As explained above, according to the present invention, the long groove on the foot lever side is engaged with the shaft portion protruding from the opening side of the housing, and the pair of locking protrusions provided on the foot lever are connected to the inner edge of the opening. Since the foot lever is latched to the base lever, the elastic deformation of the foot lever can be skillfully used to easily and reliably attach and detach from the outside of the casing. It has an excellent effect of significantly improving sexual performance.
