Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a push button device for consumer appliances in which a purpose is achieved by pressing the button.

2. Description of the Related Art Conventionally, the push button body of a push button device has a thin hinge section formed in a direction perpendicular to the operation. Therefore, in terms of projected area, the hinge section is required in addition to the operation surface. In other words, in the pushbutton body 1, which had the structure as shown in FIG.
were arranged in a flat manner.

Problems to be Solved by the Invention However, in such a structure, the area for mounting the hinge part 3 is required in addition to the operation surface 2.If other parts are located near the operation surface 2, There were drawbacks such as space limitations such as the inability to form the hinge portion 3. Further, since the hinge portion 3 spoils the aesthetic appearance, the push button body 1 is welded to the back surface of the cabinet body 6 with a boss to hide the assembled hinge portion 3t. This necessitates a gap in the cabinet body 5 of the same size as the operating surface 2, which has the drawback of weakening the strength of the cabinet body 6. Therefore, the present invention attempts to solve problems such as the space constraints associated with assembly and the strength of the cabinet body.

Means for Solving the Problems The push button device of the present invention which solves the problems described above has a push button body which has a hinge portion serving as a rotational fulcrum, an operation surface and a mounting portion, and a cross-sectional shape shaped like an abbreviation. The push button is characterized in that deformation in the direction opposite to the operation that occurs when the push button is formed is prevented by providing a locking pawl for preventing deformation on a part of the push button body.

Effects According to the present invention, by forming the hinge portion serving as a rotation fulcrum in the same direction as the operation direction, the hinge portion can be provided within the projected area of the operation surface, and the problem of space constraints is solved. In addition, since the hinge part, which spoils the aesthetic appearance, is suppressed within the projected area of the operating surface, it becomes possible to assemble the cabinet body from the front side, and there is no need for an intermediate part of the cabinet body. The problem can be easily solved by using only one sub-layer without compromising the strength of the cabinet body. Further, by providing a locking pawl at a position substantially opposite to the mounting portion of the operation surface of the push button main body, deformation in the direction opposite to the operation can be prevented.

Example Embodiments of the present invention will be described below with reference to the accompanying drawings.

1 and 2 show an embodiment of the present invention, in which 7 is a push button body made of synthetic resin, an operating surface 8, a thin hinge portion 9 that serves as a rotational fulcrum, a mounting portion 10 of the push button body 7, Claw part 11 that is removable during assembly, push part 1 for pressing the switch
2 are integrally formed. 13 is a fitting, 14 is a switch, and 16 is a concave portion of the fitting 13, which has a regulating protrusion 13ai on the bottom surface and a lip 13b'i on the side wall.

The push button body 7 is assembled to the fixture 13 by inserting the fixture 10i of the push button body 7 between the regulating protrusion 13a and lip 13b provided in the recess 16 of the fixture 13. By hooking the claw portion 11 at the tip through a hole provided in the bottom of the recess 16 to the protrusion 16a on the back surface of the recess 15, a detachable assembly can be achieved. At this time, the regulating convex portion 1
Sas! By setting the pitch of the push button 13b to be the same as the wall thickness of the mounting portion 1o, it is possible to prevent the push button body 7 from shaking.

The operation of the push button device configured as described above will be explained below.

First, when operating the push button body 7, an external force is applied to the operation surface 8 with a user's finger or the like. At this time, the hinge part 9 becomes a rotational fulcrum, the operating surface 8 performs a rotational movement, and the pushing part 12 integrated with the operating surface 8 passes through a hole provided in the bottom of the recessed part 16 and presses against the hole. After the pusher 12 presses the switch 14 arranged in this way and the external force on the heel operation surface 8 is released, the operation surface 8 returns to its initial position due to the elastic action of the hinge section 9.

At this time, if the initial angle between the operating surface 8 and the mounting portion 1o is too wide, a step difference between the operating surfaces 8 will occur as shown in FIG. 3.

Further, when a sword is applied in the opposite direction to the operating surface 8t as an abnormal use, the hinge portion 9 is bent so as to engage with the bottom surface of the recess.

Effects of the Invention As described above, the present invention allows configuration within the projected area of the operation surface by forming the hinge portion that serves as a rotational fulcrum in the same direction as the operation, and also allows assembly from the front side of the product. This eliminates the need for an intermediate part of the cabinet body as a fixture, and the strength of the cabinet body is not compromised, which solves the problem of space constraints during assembly and the strength of the fixture. In addition, the deformation of the hinge part due to the structure is prevented by the locking pawl, and the practical effect is great, such as ensuring reliable assembly.
