Abstract

<P>PROBLEM TO BE SOLVED: To lessen a gap before operation between a lock knob and a push knob without causing a chance that the lock knob comes to hit the push knob when locking operation is applied to it. <P>SOLUTION: In this switching arrangement wherein the lock knob 3 is provided by bringing it close to the push knob 2 in a configuration in which a part of it is displaced toward the push knob 2 side by locking operation, pushing means 31, 32 to push the push knob 2 in the direction of pushing operation by transmitting the displacement during the locking operation of the lock knob 3 to the push knob 2 are provided. Thereby, when the locking operation is applied to the lock knob 3, the push knob 2 is pushed in the direction of the pushing operation, and as a result, the gap between the lock knob 3 and the push knob 2 is enlarged to G11 from a conventional gap G2. Therefore, it can be avoided that the lock knob 3 comes to hit the push knob 2 without securing the gap G1 large between the lock knob 3 and the push knob 2 before operation. <P>COPYRIGHT: (C)2006,JPO&NCIPI

Description

  The present invention relates to a switch device having a lock knob and a push knob.

2. Description of the Related Art Conventionally, for example, in a switch device for a vehicle, particularly an automobile, a switch having a lock knob and a push knob is provided for a steering switch provided on a steering wheel, for example.
FIGS. 4 and 5 show an example of the conventional structure itself. In particular, as shown in the front view of FIG. 4, one push knob 2 is arranged on the body 1, and two lock knobs are provided on the left and right sides thereof. 3 are arranged close to each other.

  The push knob 2 can be pushed back and forth (a direction orthogonal to the paper surface of FIG. 4, a direction indicated by an arrow A in FIG. 5), and is guided by, for example, a cylindrical guide portion 4 of the body 1 shown in FIG. It has become so. The lock knob 3 is supported on the body 1 by a shaft portion 5 and can be locked (swinged) in the front-rear direction (a direction orthogonal to the paper surface of FIG. 4, a direction indicated by an arrow B in FIG. 5).

  A push switch body 6 and lock switch bodies 7 and 8 are provided at the push operation direction destination of the push knob 2 and the lock operation direction destination of the lock knob 3, respectively. Each of these comprises a thin switch, and more specifically, a contact holder portion 13, which is provided on an elastic sheet 9 made of an elastic material such as rubber and supported by flexible portions 10, 11, 12 having a chevron shape. 14 and 15 are respectively composed of movable contacts 16, 17 and 18 which are provided at the front end portions, and fixed contacts 20, 21 and 22 which are provided on the opposing surfaces of the circuit board 19 so as to oppose them. The distal end portion of the push knob 2 is in contact with the proximal end portion, and the distal end portions of the pressing portions 23 and 24 provided on the back surface of the lock knob 3 are in contact with the respective proximal end portions of the contact holder portions 14 and 15. .

  With this configuration, when the push knob 2 is pushed, the contact holder portion 13 is pushed to bring the movable contact 16 into contact with the fixed contact 20, and in short, the push switch body 6 responds. When the lock knob 3 is locked, the contact holder portion 14 is pushed by the pressing portion 23 by the locking operation on the pressing portion 23 side to bring the movable contact 17 into contact with the fixed contact 21. In short, the push switch body 7 responds. Further, in the locking operation on the pressing portion 24 side, the contact holder portion 15 is pushed by the pressing portion 24 to bring the movable contact 18 into contact with the fixed contact 22, and in short, the push switch body 8 responds.

  In the case of the above conventional one, when the lock knob 3 is locked, a part thereof is displaced to the push knob 2 side. FIG. 6 shows this state by an example in which the pressing portion 23 side of the lock knob 3 is locked. In this case, the pressing portion 24 side of the lock knob 3 is pushed by the push knob 23 when the pressing portion 23 side of the lock knob 3 is locked. It is displaced to the 2 side, and the gap between them is reduced from G1 to G2. Although not shown, when the pressing portion 24 side of the lock knob 3 is locked, the pressing portion 23 side of the lock knob 3 is displaced to the push knob 2 side, and the gap between them decreases from G1 to G2.

  For this reason, it is conceivable that the lock knob 3 will come into contact with the push knob 2 due to an unavoidable assembly error. If this happens, the push switch bodies 7 and 8 cannot be fully operated. Therefore, it is necessary to ensure a large gap G1 before the operation between the lock knob 3 and the push knob 2, and as a result, the appearance is not good.

  The present invention has been made in view of the above-described circumstances, and therefore the object is to hit the push knob when the lock knob is locked in the gap before the operation between the lock knob and the push knob. Therefore, it is desirable to provide a switch device that can be made small.

  In order to achieve the above object, a switch device of the present invention includes a lock knob and a push knob, a lock switch body that responds to a lock operation of the lock knob, and a push switch body that responds to a push operation of the push knob. The lock knob has a configuration in which a part of the lock knob is displaced toward the push knob by the locking operation and is provided close to the push knob. It is characterized in that a pushing means for pushing the push knob in the push operation direction is provided.

  According to the above means, when the lock knob is locked, the push knob is pushed in the push operation direction via the pushing means, and as a result, the gap between the lock knob and the push knob is increased. Therefore, it is possible to avoid the lock knob from hitting the push knob without securing a large gap between the lock knob and the push knob before the operation.

Hereinafter, an embodiment (one embodiment) of the present invention will be described with reference to FIGS.
First, in FIGS. 1 to 3, the same parts as those in FIGS. 4 to 6 are denoted by the same reference numerals. Therefore, the description of the same parts is omitted, and only different parts will be described. That is, pushing means 31 and 32 are provided between the lock knob 3 and the push knob 2. More specifically, in this case, the pushing means 31 and 32 are convex as second pushing portions provided on both side portions (positions aligned with the pushing portions 23 and 24) near the push knob 2 on the back surface of the lock knob 3. Parts 33, 34, and overhang parts 35, 36 as push-in receiving parts provided in the intermediate part of the push knob 2 positioned at the tip of these (the lock operation direction of the lock knob 3), It is close.

  In this configuration, if the lock knob 3 is locked, the protrusion 33 of the push-in means 31 pushes the overhanging portion 35 by the lock operation on the pressing portion 23 side, and the displacement during the lock operation of the lock knob 3 is applied to the push knob 2. Then, push the push knob 2 in the push operation direction. Further, in the locking operation on the pressing portion 24 side, the convex portion 34 of the pushing means 32 pushes the overhanging portion 36 to transmit the displacement at the time of the locking operation of the lock knob 3 to the push knob 2, and the push knob 2 is moved in the push operation direction. Push in.

FIG. 1 shows the state at that time as an example of the former (the lock operation on the pressing portion 23 side). When the push knob 2 is pushed in the push operation direction, the space between the lock knob 3 and the push knob 2 is shown. The gap increases from the conventional G2 to G11 (the same applies to the locking operation on the pressing portion 24 side).
Therefore, it is possible to avoid the lock knob 3 from hitting the push knob 2 without securing a large gap G1 between the lock knob 3 and the push knob 2 before the operation, unlike the conventional one. Since the gap G1 before the operation between the lock knob 3 and the push knob 2 can be reduced, for example, the appearance can be improved.

Note that when the push knob 2 is pushed by the locking operation of the lock knob 3 described above, the push amount of the push knob 2 is not an amount until the movable contact 16 of the push switch body 6 is brought into contact with the fixed contact 20. Of course.
The present invention is not limited to the embodiments described above and shown in the drawings, and can be implemented with appropriate modifications within a range not departing from the gist.
