Description

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

Prior Art Conventionally, the push button body of a push button device has formed a thin hinge portion in the direction perpendicular to the operation. Therefore, in terms of projected area, the structure of the hinge portion is required in addition to the operation surface. The structure was as shown in Figures 4 and 5. That is, in the push button body 1, the operating surface 2 having the operating shaft 4 of the switch 6 and the hinge portion 3 formed of a thin wall serving as a rotational fulcrum are arranged in a plane.

Problems to be Solved by the Invention However, in such a structure, an area other than the operating surface 2 is required to provide the hinge portion 3.

In other words, when other parts are located near the operation surface 2, there is a drawback in that space constraints such as the inability to form the hinge portion 3 occur. In addition, since the hinge part 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 assembly hinge part 3. This requires a spacer section in the cabinet body 5 that is the same size as the operating surface 2, which has the disadvantage that the strength of the cabinet body 5 is weakened.

The present invention attempts to solve problems such as space constraints associated with assembly and 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. It is characterized by a restricting protrusion that is formed on the hinge portion and prevents the operating surface from rotating beyond a certain level in order to protect the hinge portion from excessive force during operation.

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. Further, since the hinge portion, which spoils the aesthetic appearance, is suppressed within the projected area of the operating surface, it is possible to assemble the cabinet body from the front side, and there is no need for an intermediate portion of the cabinet body. Therefore, the problem can be solved without impairing the strength of the cabinet body. Further, in the present invention, since the mounting tool is provided with a convex portion for regulating the operating surface, the hinge portion can be protected from excessive force applied to the operating surface.

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 A is a push button body made of synthetic resin, an operation surface 8, a thin hinge portion 9 serving as a rotational fulcrum, a mounting portion 10 of the push button body 7, A claw 11 that is detachable during assembly and a push part 12 for pushing the switch are integrally formed. 13 is a fitting, 14 is a switch,
Reference numeral 15 designates a recessed portion of the fixture 13, and the bottom surface of this recessed portion 16 has a regulating projection 13a, and the opposing side wall has a receiving portion 13c.
and ribs 13b. When assembling the push button body 7 to the fixture 13, the mounting part 1o of the push button body 7 is inserted between the regulating convex portion 13a provided in the recess 16 of the fixture 13 and the rib 13b.
By inserting the nail part 11 at the tip of the mounting part 10,
By passing through a hole provided on the bottom surface of the recess 15 and hooking it onto the projection 15a on the back surface of the recess 16, a removable assembly can be achieved. Also, at this time, the regulating convex portion 13a1 rib 13
By setting the pitch b to be the same as the thickness of the mounting portion 10, shaking of the push button body 7 can be prevented.The operation of the push button device constructed as above will be described 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, which is integrated with the operating surface 8, passes through a hole provided in the bottom of the recessed part 15 and enters the hole. Press the switch 14 arranged to face each other. The push part 12 pushes the switch 14 and the operation surface 8
After the external force is released, the operating surface 8 returns to its initial position due to the elastic action of the hinge portion 9. When excessive force is applied to the operating surface 8, stress is applied to the hinge portion 9 due to the extreme rotation of the operating surface 8. Furthermore, since the hinge portion 9 is thin, it is conceivable that it may be deformed and broken by excessive force. For this reason, in this example, a regulating convex portion 13a and a receiving portion 13c are provided to receive the back surface of the operating surface, and as shown in FIG. 3, the hinge portion 9 is protected by receiving rotation of the operating surface beyond a certain level. There is.

In addition, in this embodiment, by making the rotational fulcrum part thin and giving it a hinge effect, the same elastic action can be obtained not only with resin but also with light metals such as aluminum and miniram, and the same effect can be achieved. Effects As described above, the present invention enables configuration within the projected area of the operation surface by molding the hinge portion, which serves as a rotation fulcrum, in the same direction as the operation direction, 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 assembly space constraints and the strength of the fixture. In addition, it is possible to easily protect the hinge part from excessive force, which affects the product life.
Its practical effects are significant.
