[0008]

Problems to be Solved by the Invention
The handlebar switch 1 ′ having the configuration introduced in 1) has room for improvement in the following points. That is, (a) with respect to the fixing plate 120, three supporting pieces 122, 124, 126 are projected so as to project at a right angle from the plate-shaped main portion 121.
Need to be formed. As mentioned above, the two support pieces 1
22 and 124 are holes 123 into which the projections 113 and 115 protruding from the main part 111 of the contact plate 110 in the same plane are fitted.
. 125, and another support piece 126
Is for contacting a protrusion portion 116 protruding from the main portion 111 of the contact plate 110 in the same plane with the top portion. It can be said that the fixed plate 120 having the three support pieces 122, 124, and 126 has a complicated shape and therefore an extra manufacturing cost.

(B) When assembling the contact plate 110, the fixed plate 120 and the movable plate 130, it is necessary to carefully determine the angle of the contact plate 110 about the insertion shaft. Contact plate 11
The protrusions 113 and 115 of 0 are the support pieces 12 of the fixed plate 120.
Until it fits into the hole 123/125 in 2.124,
This is because no one will guide you to the appropriate position.

The invention according to the claim is a handle switch including a contact plate, a fixed plate, a movable plate, etc., which simplifies the shape of the fixed plate (or the contact plate) and facilitates the assembly between the fixed plate and the contact plate. The purpose is to

[0011]

According to a first aspect of the present invention, there is provided a handlebar switch in which a contact plate having contacts arranged on a plane and a fixing plate separate from the contact plate are arranged such that main portions thereof are parallel to each other and are spaced apart from each other. A handle switch which is coupled to the movable plate with an operation knob and is swingably supported between the movable plate and an insertion shaft portion, and a movable contact which comes into contact with the contact is attached to the movable plate. ) The contact plate and the fixed plate are prevented from being separated by fitting the protrusions and holes arranged at each of the two locations, and the contact between the inserted shaft part (insertion shaft part) and other parts. Two supports which are joined together by being prevented from tilting by mutual contact at the parts, b) the holes mentioned above projecting from the main part of the contact plate or fixing plate towards the other side (that is, at right angles to the main part). Inside each of the pieces, The contact portion of the serial is constituted by the formed step portion and the other party to the formed protrusion within one of said support pieces - that characterized.

Such a handlebar switch is constructed as shown in FIGS. 1 to 3, for example. However, for example, the “supporting piece” in the above b) may not only project from the fixed plate toward the contact plate, but may also project from the contact plate toward the fixed plate. Further, the "insertion shaft portion" may be attached to the contact plate or the fixed plate, may be attached to the movable plate, or may be an insertion component independent of each plate.

In the handlebar switch having the above characteristics, the number of supporting pieces formed by projecting the contact plate and the fixed plate from the main parts of either of them to the other side is smaller than the conventional one, and only two are required. . Conventionally (Fig. 5) has been used as a contact part that makes mutual contact to prevent inclination between the fixed plate and the contact plate.
A separate support piece (reference numeral 12 in FIG. 5) as shown in FIG.
This is because, instead of forming 6), a step portion (reference numeral 26 in FIG. 1) integrated with either of the two support pieces is used. The need for two supporting pieces, which had to be formed by projecting at right angles from the plate-shaped part that is the main part, was sufficient to simplify the shape of the part (contact plate or fixed plate). , Which leads to a reduction in manufacturing cost.

The handle switch described above is also characterized in that the contact plate and the fixed plate can be easily assembled.
When the protrusion formed on the contact plate (or the fixed plate) is fitted into the hole in the support plate of the fixed plate (or the contact plate), the side portion (reference numeral 22 in FIG. 1) of the support piece described in b) above ( This is because the protrusions (13 and 15) are automatically guided to the positions of the holes (23 and 25) by moving the protrusions (16 in FIG. 1) along the protrusions (from the top to the step).
In other words, at the time of assembly, the contact plate centered on the insertion shaft
The angle between the fixing plates can be easily and properly determined.

Even in this handle switch, the movable contact is displaced as the movable plate swings,
The contact state between the contact on the contact plate and the movable contactor is changed, thereby opening and closing the circuit as a switch.
In that respect, it is similar to the conventional handle switch (of FIGS. 5 and 6).

The handlebar switch described in claim 2 is
In particular, it is characterized in that the support piece and the step portion are formed on the fixed plate, and the protrusion and the protrusion portion are formed on the contact plate.

In this handlebar switch, the structure of the contact plate is particularly simplified. A support piece or the like formed at a right angle to the plate-shaped portion that is the main portion is formed on the side of the fixed plate, while the contact plate has a projection that fits into the hole of the support piece and a projection that contacts the stepped portion. This is because it suffices if it is formed in the same plane as the plate-shaped portion. Since it is common for the contact plate to have a contact that has the essential function of a switch attached to it to connect an electric wire, simplifying the structure of the contact plate enables work such as contact mounting and wire connection. Is simplified, and the manufacture of the handlebar switch is facilitated as a whole.

The handlebar switch according to the third aspect of the present invention further includes a portion other than the two support pieces and the step portion.
It is characterized in that the fixed plate and the contact plate are opened. That is, in the example of FIGS. 5 and 6, the two support pieces 122
In addition to 124, the support plate 126 closes the gap between the fixed plate 120 and the contact plate 110. However, as shown in FIGS. 1 and 2, the support plate and the stepped portion (in FIG. Openings 20 are provided in portions other than the reference numerals 22, 24, 26).
By installing b, etc., fixed plate (same 20), contact plate (same 1)
The projecting part that closes the gap between 0) is not provided.

In such a handle switch, it is possible to set a large swing range (size of the movable plate itself, swing radius, swing angle) with respect to the movable plate disposed between the contact plate and the fixed plate. Is. Since the space between the fixed plate and the contact plate is open except for the above-mentioned support piece and stepped portion, the size of the movable plate can be determined so that part of the fixed plate / contact plate protrudes from the outer edge. This is because the end of the movable plate can be located very close to the outer edges of the fixed plate / contact plate even if such protrusion is not allowed. That is, in the case of FIG. 6, the size of the movable plate 130 is limited so as not to hit the support piece 126, but as in the example of FIG. 2, the movable plate (reference numeral 30) is a fixed plate (reference numeral 20 in FIG. 2). ) Etc. can be enlarged to the vicinity of the outer edge (the same 20a). If the swing range of the movable plate increases as described above, the operating range of the movable contactor attached to the movable plate also increases, which is convenient for accurately and stably switching contact / separation with the contacts on the contact plate. Good.

According to a fourth aspect of the present invention, in particular, the handlebar switch is a dimmer switch that switches the headlamp beam by operating the operating knob.

The dimmer switch for switching the beam of the headlamp between the upward direction and the downward direction requires that the position of the movable contactor be appropriately switched between the two sets of contacts, and that the handle be easy to operate. It is suitable to have the features of claims 1 to 3 because it has to be attached to the. That is, it can be said that this dimmer switch having the features described in the above claims is a preferable handlebar switch that has a simple component shape, is easy to assemble, and has a smooth opening and closing of a circuit.

In the handlebar switch according to the fifth aspect of the invention, in particular, the contact point of the contact plate is provided in the upper half portion (generally the upper half position) of the contact plate when it is arranged on the handle, The operating range of the knob is 15 ° or more.

Such a handlebar switch has the advantages that the movable contactor and the contact point are accurately brought into contact with each other and separated from each other, and that the durability is excellent. The reason why the contact between the contacts is accurate is that the operating range of the operation knob (and thus the operating range of the movable plate and the movable contact) is as large as 15 ° or more. If the movable contact has a large operating range, a large distance can be provided between the contacts to be switched, and the contact state and the separated state can be easily distinguished. In that sense, it is more preferable that the operating range of the operating knob is 30 ° or more, and in consideration of the ease of operation, the operating range is 5 °.
It is preferably about 0 ° or less.

FIG. 3 shows the main parts of the dimmer switch 1, and FIGS. 3 (a), (b), and (c) show side views of the movable plate 30, the contact plate 10, and the fixed plate 20, respectively. Note that FIG. 4 is a perspective view showing an example of mounting the handlebar switch in the motorcycle as previously introduced. In addition, in the following description, when referring to “upper” or “lower”, unless otherwise specified, the
The directions below shall be pointed out.

As shown in FIG. 4, the dimmer switch 1 is mounted in a casing 4 fixed to a handle frame A and is arranged at a position near a handle grip B as one of the handle switches in a motorcycle. The mounting state and the internal structure in the casing 4 are as shown in FIG. The dimmer switch 1 is fixed to the inside of the casing 4 with only the operation knob 32 being exposed to the outside of the casing 4. When the driver operates the operation knob 32 with a fingertip and pushes the upper portion or the lower portion, the movable plate 30 integrated with the knob 32 swings around the support hole 31. As shown in FIG. 2, the movable plate 30 has a movable contact 40 made of copper alloy (a contact portion 41 that is raised toward the contact plate 10 in the front of the drawing).
a, 41b, and 41c) are fixed, and the contactor 40 is displaced along with the swing of the movable plate 30, so that the contact point plate 10 arranged along the contactor 40 (excluded in FIG. 2). Inside contacts 12a, 12b, 12c
It is possible to change the state of contact with the beam (shown in phantom in FIG. 2) so that the beam can be switched upward or downward in the traveling direction. The contact plate 10 has contacts 12a, 12b, 12c on the surface close to the contactor 40.
There is a copper alloy piece to be used, and the electric wire (the same) from each contact to the headlamp lighting circuit (not shown) is connected to the back side (that is, the front side of the paper surface of FIG. 1). Movable contact 4
0 contacts the contacts 12a and 12b at the contact portions 41a and 41b, respectively, as shown in FIG. 2, the low beam of the headlamp is turned on and the knob 32 is operated to operate the contact 4
0 contact portions 41a and 41c are contact points 12a and 12 respectively.
The high beam is lit when it contacts with c. Contact 12a
The contact plate 10, the fixed plate 20, and the movable plate 30 are made of a material such as a resin having no conductivity, except that the 12b and 12c and the contact 40 are made of a copper alloy.

The movable plate 30 integrated with the operation knob 32 is
It is assembled between the contact plate 10 and the fixed plate 20 which are connected as shown in FIG. Main part 11 of contact plate 10 and fixed plate 20
The main plate 21 and the main part 21 are both plate-shaped, but the movable plate 30 is swingable as described above between the two arranged at a distance.
Was placed. In order to swingably support the movable plate 30, a support hole 31 of the movable plate 30 shown in FIG.
Further, in the contact plate 10 of the same (b), an insertion shaft portion extending from the shaft portion 14 to the opposite side (back side of the paper surface of the drawing) and the fixing plate 20 of the same (c) front side (front side of the paper surface of the drawing). And the insertion shaft portion 28 extending to are inserted in a so-called clearance fit state.

The connection between the contact plate 10 and the fixed plate 20 is shown in FIG.
As described above, the projections 13 and 15 provided on the contact plate 10 are fitted into the holes 23 and 25 provided on the fixed plate 20, respectively. The fixed plate 20 includes a plate-shaped main portion 21.
Forming two support pieces 22 and 24 at right angles to the contact plate 10 and inserting a hole 23 in the support pieces 22 and 24.
・ 25 is provided. The protrusions 13 and 15 are formed in the same plane as the main portion 11 of the contact plate 10.
By fitting the protrusions 13 and 15 into the holes 23 and 25,
The contact plate 10 and the fixed plate 20 can be combined in a state that is difficult to separate.

However, each of the protrusions 13 and 15 has a hole 2
Since the contact plate 10 (or the fixed plate 20) may be displaced so as to be tilted around the positions of the protrusions 13 and 15 only by fitting it into the 3/25, contact portions are also provided at other positions. . One of the contact portions is the insertion shaft portion (see FIG. 3).
It is between the peripheral wall portion of the support hole 31 of the movable plate 30 (FIG. 3A, etc.) and the like (28 in FIG. 3C). As shown in FIG. 1, the other contact portion is between the step portion 26 formed in the supporting piece 22 of the fixed plate 20 and the protruding portion 16 formed in the same plane as the main portion 11 of the contact plate 10. It is provided in. Even if the contact plate 10 inclines about the line connecting the protrusions 13 and 15 in the direction in which the insertion shaft portion separates from the support hole 31, it is prevented by the contact between the step portion 26 and the protrusion portion 16. In addition, the inclination in the direction in which the step portion 26 and the protruding portion 16 separate from each other means that the insertion shaft portion is
It is prevented by touching the periphery of 1.

As shown in FIG. 1, the fixed plate 20 is not provided with a portion projecting toward the contact plate 10 except for the portions where the two support pieces 22 and 24 and the step portion 26 are provided. Therefore, a large opening 20b is formed between the contact plate 10 and the fixed plate 20 in the portion from the support piece 22 (step portion 26) to the support piece 24.
Note that the protrusion 27 shown in FIG. 1 and the like is for mounting, and the dimmer switch 1 is placed inside the casing 4 by inserting a set screw 4a into a hole provided in a part thereof as shown in FIG. Fixed to.

The dimmer switch 1 configured as described above
Has the following advantages. a) The fixing plate 2 for connecting the contact plate 10 and the fixing plate 20.
The part that projects at a right angle from the main part 21 of 0 is the support piece 2
There are only 2/24. This is because the stepped portion 26 is integrally formed with the support piece 22 in a portion that comes into contact with a part of the contact plate 10 (projection portion 16) in order to prevent the contact plate 10 and the like from tilting. Since the number of protruding parts is smaller than in the conventional case, the fixing plate 20 has a simple shape and can be manufactured at low cost.

B) Easy to assemble. When the contact plate 10 is assembled to the fixed plate 20, the protrusion 16 is fixed to the fixed plate 2
The position relationship between the contact plate 10 and the fixed plate 20 is appropriately determined by fitting the contact plate 10 to the side portion 22a of the support plate 22 of 0, and the contact plate 10 is pushed down in that state to contact the contact plate
This is because the protrusions 13 and 15 are smoothly fitted into the holes 23 and 25 of the support piece 22.

C) The size of the movable plate 30 is related to the large opening between the fixed plate 20 and the contact plate 10 except for the supporting pieces 22 and 24 and the step portion 26 as shown in FIG. (Distance and area from the support hole 31 in FIG. 2, which is the center of swing, to the end) can be increased. The outer edge 20a of the fixed plate 20 (the edge formed in an arc shape so as not to come into contact with the handle frame A as shown in FIG. 2) has only the opening 20b, and the movable plate is very close to the outer edge 20a. This is because the ends of 30 can be located. When the movable plate becomes large, the movable range of the movable contactor 40 attached to the movable plate can be increased, and the contact 12 on the contact plate 10 can be expanded.
The switching function can be accurately set with a wide interval between a, 12b, and 12c. In the illustrated example, the operating angle of the contact 40 (that is, the operating angle of the operating knob 32)
The contact angle was set to be as wide as 30 °, and a considerable space was provided between the contacts 12a, 12b, 12c.

D) The distance between the two contact portions that prevent the contact plate 10 from being displaced so as to be inclined with respect to the fixed plate 20, that is, the distance between the insertion shaft portion (in the vicinity of the support hole 31) and the protruding portion 16. , Which is larger than the conventional distance (between the insertion shaft portion and the protruding portion 116). This is because the step portion 26 provided in the support piece 22 is located at the end of the edge portion 20a of the fixed plate 20 that is far from the insertion shaft portion. Since the contact plate 10 is prevented from tilting by the two contact portions, the distance between them is increased as described above, which brings about the advantage that the posture of the contact plate 10 assembled to the fixed plate 20 is stabilized. .

[0034]

The handle switch described in claim 1 has the following effects. -Since only two supporting pieces need to be formed on one of the two parts for connecting the contact plate and the fixed plate, the shape of the part can be simplified and the manufacturing cost can be reduced.・ Forming a step portion integrally with any of the above support pieces,
Since the projecting portion of the counterpart component is brought into contact therewith, the support piece and the projecting portion are put together to properly position the contact plate and the fixed plate, and both components can be easily assembled.

In the handlebar switch according to the second aspect of the present invention, in particular, the structure of the contact plate is simplified, and therefore the work of attaching the contacts and connecting the electric wires is facilitated, so that the whole manufacturing is facilitated.

Further, in the handlebar switch according to the third aspect, since the open portion is secured between the fixed plate and the contact plate, the operating range of the movable plate and the movable contact is increased,
The contact / separation with the contact on the contact plate can be switched more accurately.

According to the handlebar switch of the fourth aspect, a preferable dimmer switch having the above effects can be obtained.

In the handlebar switch according to the fifth aspect of the invention, since the operating range of the operation knob is large, contact and separation between the movable contact and the contact are performed particularly accurately, and the durability is also excellent.・ Because the contact is provided in the upper half of the contact plate, the contact is hard to get wet and the durability of the switch is excellent.
