【Example】

 An embodiment of the present invention will be described below with reference to FIGS. FIG. 1 is an external perspective view of the foot pedal device, and FIG. 2 is a sectional view taken along the line AA. The foot pedal device includes a main body case 1 made of synthetic resin, and a plurality of (three in this embodiment) pedals 2 made of synthetic resin mounted in parallel with the main body case 1.

The body case 1 is formed in a substantially box shape in which the front side (left side in FIG. 2) is slightly lower than the rear side (right side in FIG. 2). The front portion of the main body case 1 is formed with a gentle sloping portion, and a cushion material 3 is provided below the pedals 2 in the sloping portion. A push button type switch 4 is provided below the pedals 2 in the main body case 1 on the rear side of the cushion material 3. Each switch 4 is pressed onto the board 6 by a board 6 screwed to the lower end surface of a boss 5 formed by hanging down on the inner surface of the body case 1, and a rib 7 formed on the inner surface of the body case 1. It is composed of a rubber member 8 attached. The rubber member 8 has an elastically deformable bulging part, and the upper part of this bulging part projects upward through the fool hole 9 of the main body case 1, and when this projecting part is pressed and elastically deformed, as shown in FIG. As shown, the movable contact 10 provided inside the bulge contacts the pair of fixed contacts 11 provided on the upper surface of the substrate 6 to bring the pair of fixed contacts 11 into conduction. Further, a pedal mounting recess 12 is provided at the rear of the body case 1 so as to correspond to each pedal 2. A bottom plate 13 is arranged at the bottom of the body case 1. The bottom plate 13 is screwed to the lower end surface of a mounting column 15 provided on the lower surface of the bottom plate 13 via rubber feet 14 so as to hang down from the inner surface of the main body case 1.

On the other hand, the pedal 2 is formed of a synthetic resin in a substantially flat plate shape, and an elastic support portion 16 for supporting the pedal 2 so as to be vertically displaceable is integrally formed at a rear end portion thereof. In this elastic support portion 16, a curved portion 17 formed to be thinner than the pedal 2 is continuous to the rear end portion of the pedal 2, and the lower end portion of the curved portion 17 is thicker than the curved portion 17 and thus the pedal 2 The mounting portion 18 is thinner than the thickness of the above. As shown in FIG. 4, the elastic support portion 16 is attached to the main body case 1 by inserting the attachment portion 18 into the pedal attachment concave portion 12 of the main body case 1 and fitting the same. It is designed to support upwards. In this case, in order to increase the strength, the attachment portion 18 may be adhered while being inserted into the pedal attachment recess 12. An inclined pressing portion 19 is provided on the lower surface of the pedal 2 so as to press the upper end portion of the rubber member 8 of the switch 4 substantially in parallel when the pedal 2 is depressed and is displaced downward, corresponding to the switch 4. There is.

In such a foot pedal device, as shown in FIG. 2, the pedal 2 is normally supported above the main body case 1 by the elastic support portion 16. In this state, the pedal 2 is supported by the elastic support portion 16. When the pedal is depressed against the elasticity, the elastic support portion 16 is elastically deformed near the curved portion 17 as shown in FIG. 3, and accordingly, the pedal 2 is rotated counterclockwise around the curved portion 17. Then, the pressing portion 19 of the pedal 2 presses the rubber member 8 of the switch 4 of the main body case 1 to turn on the switch 4, and the lower surface on the front end side of the pedal 2 becomes the cushion material 3 of the main body case 1. The lower limit position is regulated by contact. Although the deformation of the pedal 2 itself is ignored here, the pedal 2 itself actually bends to some extent. Then, when the depression on the pedal 2 is released, the pedal 2 returns to its original initial position by the elastic restoring force of the elastic support portion 16, and the rubber member 8 of the switch 4 also returns to the original off state.

As described above, in this foot pedal device, the elastic support portion 16 that supports the front end side of the pedal 2 made of synthetic resin so as to be vertically displaceable is integrally formed with the foot pedal device. By eliminating the need for a hinge shaft or a spring member as a separate component, the number of components can be greatly reduced, and moreover, by attaching the attachment portion 18 of the elastic support portion 16 to the pedal attachment recess 12 of the main body case 1, Since the pedal 2 is attached to the main body case 1, the structure is simple, the assembling workability is good, and a low price can be obtained. In particular, as shown in FIG. 4, the pedal 2 can be mounted extremely simply because the mounting portion 18 of the elastic support portion 16 can be inserted and fitted into the pedal mounting recess 12 of the main body case 1. For this reason, for example, when the number of pedals 2 is two or one, the main body case 1 has a structure in which pedal mounting recesses 12 are provided at two positions as shown in FIG. 5, or pedal mounting as shown in FIG. Since only the structure in which the recess 12 is provided in one place is required, it is possible to easily deal with the case where the number of pedals 2 is different.

[0011]

[Effect of device]

 As described above, according to the present invention, the elastic support portion that supports the other end of the pedal made of synthetic resin so as to be vertically displaceable is integrally formed with one end of the pedal. Since the hinge shaft and spring member are not required, the number of parts can be reduced, and the pedal is attached to the main body case by attaching the elastic support part to the main body case, so the structure is simple and the assembly workability is easy. It's good, you can get a low price, and you can use the same pedal regardless of the number of pedals attached to the main body case.
