Description

[Detailed description of the invention] The present invention relates to an improvement in the case mounting structure of a switch device, and in particular, it is possible to arbitrarily select and mount the switch knob of a switch device on multiple adjacent planes of the case, thereby allowing one type of switch device to be mounted on multiple adjacent planes of the case. The structure is characterized in that it is possible to attach multiple types of switch devices.

It is well known that a conventional switch device has a switch knob fixed only to a predetermined plane of a case. When two types of cases with the same shape are provided with switch knobs placed on the back or side of the case, two types of cases must be formed, which poses the problem of a large number of parts. .

An object of the present invention is to provide a switch device in which a switch knob can be selectively fixed to a plurality of adjacent planes of a case with one type of configuration, and the switch device can be detachably and elastically connected to the case.

In order to achieve the above object, the present invention includes two planes arranged perpendicularly to each other at the corners of the case and each having an opening of approximately the same size, and a fixed plane adjacent to the planes and arranged opposite to each other. a case equipped with a mounting part having a switch knob, and a switch body having a coupling surface that is arranged to overlap the end of the switch plate to which the switch knob is mounted and that is perpendicular to the switch plate and that can be coupled to the fixed surface, An elastically deformable coupling member having a positioning protrusion is formed on one of the fixing surface of the case and the coupling surface of the switch body, and the other is formed with a step that can be coupled with the positioning protrusion to hold the switch body in the case. The switch plate can be selectively fixed on a plurality of planes of the case by selectively inserting the switch body into a predetermined opening of the case plane from at least two directions. shall be.

The present invention will be described below based on an embodiment of the present invention shown in the drawings.

FIG. 1 shows a first embodiment of the present invention, and is an external view of the mounting portion 6 of the switch body 4 and the switch body 4 in the case 2 of a watch. Mounting part 6 is case 2
The first side surface 8 and the second side surface 10 are formed with openings 12 and 14 of approximately the same size, and these openings 12,
14 are orthogonally arranged. Approximately square fixing surfaces 16, 16 are arranged overlapping each other in the mounting portion 6, and each fixing surface 16 is formed with two guide protrusions 20, 22 and a stepped portion 24. Further, the fixed surface 16 has a first recess 26 and a second recess 28 with the stepped portion 24 as a boundary.
One end of the first recess 26 reaches above the second side surface 10 of the case 2, and the other end is formed into an inclined surface 30. Further, the second recess 28
is located approximately at the center of the fixed surface 16. The guide protrusions 20, 22, the stepped portion 24, the first recess 26, and the second recess 28 of each fixing surface 16 are the same, and are opposed to each other and arranged in an overlapping position. A through hole 34 is formed in the inner surface 32 of the mounting portion 6, and a lead wire 36 passes through the through hole 34.

The switch body 4 is made of a synthetic resin member and includes a switch plate 38, two opposing coupling surfaces 40, and two opposing side surfaces 42, and has a substantially rectangular parallelepiped shape. A rotary type switch knob 44 and a sliding type switch knob 46 are attached to the switch plate 38, and by turning these switch knobs on and off, the clock circuit housed inside the case 2 (not shown) can be turned on and off. ) can be controlled. Each coupling surface 40 has a fixing surface 1 of the case 2.
Two sets of guide grooves 48, 48 and 50, 50 are formed that can engage with the guide protrusions 20, 22 formed in the guide grooves 6. Further, each bonding surface 40 is cut leaving a portion, and a bonding member 52 that can be elastically deformed in the directions of arrows A and B is formed. A positioning protrusion 54 is formed.

The first embodiment of the present invention is constructed as described above, and the effects of the first embodiment will now be described.

In Figure 2, the switch body 4 in Figure 1 is indicated by arrow C.
The state in which it is inserted into the mounting part 6 of the case 2 from this direction is shown. The switch body 4 is guided into the mounting part 6 by the guide groove 48 engaging with the guide protrusions 20 and 22 of the fixing surface 16 of the mounting part 6, and at this time, the positioning protrusion 54 on the coupling surface 40 of the switch body 4 is inserted into the first recess 26 of the fixing surface 16. Then, as the switch body 4 is further moved in the direction of arrow C, the positioning protrusion 54
is moved by the elastic deformation action of the coupling member 52 and rides up the slope 30, and then climbs over the stepped portion 24 and falls into the second recess 28. Thereby, the switch body 4 is securely fixed to the mounting portion 6. In this state, the switch knobs 44 and 46 are arranged on the second side surface 10 of the case 2, so the switch operation can be performed from the second side surface 10 side of the case 2.

The state shown in FIG. 3 is a state in which the switch body 4 shown in FIG. 1 is inserted and fixed into the mounting portion 6 of the case 2 from the direction of arrow D. Connection surface 4 in switch body 4
Since the positioning protrusion 54 of 0 is formed approximately at the center of the coupling surface 40, and the second recess 28 of the fixing surface 16 of the case 2 is also formed approximately at the center of the fixing surface 16, the operation is completely different from that shown in FIG. 3rd in the same action
It is securely fixed in the state shown in the figure. In this state, the switch knobs 44 and 46 of the switch body 4 are
Since the switch is disposed on the first side surface 8 of the case 2, the switch operation can be performed from the first side surface 8 side of the case 2.

As described above, according to the first embodiment, the switch knobs 44 and 46 can be selectively placed on either the first side surface 8 or the second side surface 10 of the case 2 depending on the user's preference, and the switch operation is facilitated. You can improve your performance.

Further, particularly when the switch device according to the present invention is used in a timepiece mechanism case, a switch knob can be placed on the side of the case in order to enable the hands of the wall clock to be set without removing the clock from the hook. In addition, many table clocks have a switch knob on the back, and the switch knob can be placed on the back of the case for design and operability reasons. This conventionally requires two types of configurations, one for wall clocks and one for table clocks, but one type of configuration can be used for both purposes, and the number of parts can therefore be reduced. In addition, conventionally, the switch board 3
8 was fixed to the case 2 with screws or the like, but in the present invention, the switch body 4 can be connected by elastic coupling, making it extremely easy to attach and detach the switch body 4.

4 and 5 show a second embodiment of the present invention, and the same parts as in the first embodiment are given the same reference numerals and detailed explanations are omitted.

In FIG. 4, the coupling surface 48 has a positioning protrusion 5.
4 are arranged at the corners of the coupling surface 48 at positions equidistant from the switch plate 38 and the side surface 42.

In FIG. 5, the fixed surface 16 has a second side surface 10
A second recess 60 is formed at a predetermined length from the side, that is, the same length as the length l from the switch plate 38 side to the positioning protrusion 54 in FIG. The length of the second recess 60 in the longitudinal direction is equal to that of the fixed surface 16.
The length is set such that at least the length 1 from the above-mentioned switch plate 38 side to the positioning protrusion 54 is removed from both ends.

In the second embodiment, the positioning protrusion 54 and the second
Since the positional relationship of the recess 60 is configured as described above, the switch body 4 is inserted into the mounting portion 6 of the case 2 from the directions of arrows C and D and is securely fixed in the same manner as in the first embodiment. Therefore, the user can selectively place the switch knob 44 on the first side surface 8 or the second side surface 10 of the case 2 according to his/her preference.

As explained in detail above, according to the present invention, the mounting part of the switch body is configured by forming adjacent openings of approximately the same size on both adjacent planes of the corner of the case, and the mounting part is fixed. An elastically deformable positioning protrusion is formed on one of the joining surfaces of the switch body and the surface, and a second recess is formed on the other side, with which the positioning protrusion can be engaged when the switch body is inserted from at least two directions. Therefore, the switch body can be inserted and fixed into the mounting portion from at least two different directions. Therefore, the user can arbitrarily select and arrange the switch knobs on different planes of the case. As a result, the switch device can be mounted in a plurality of forms with one type of switch device mounting configuration, and this has the effect that two types of cases, which were conventionally required, can be used in one type of case.
