It is configured so that the clearance between the locking portion 34 of the button 30 is rotatable in the circumferential direction is secured.

In addition, according to the present invention, the case 10 is formed in a square shape, the pusher 50 is a push plate 54 and the push portion 54 of the rectangular plate shape to be embedded in the case 10. An elevator switch is provided, comprising a plurality of elastic pieces 52 having a proximal end integrated in front, rear, left, and right edges thereof.

Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings. 1 is an exploded perspective view of an embodiment of the present invention, Figure 2 is a perspective view showing the pressing operation of the pusher shown in Figure 1, Figure 3 and Figure 4 is a plan view showing the operating state of the button constituting an embodiment of the present invention 5 and 6 are longitudinal cross-sectional views showing main parts operating states of an embodiment of the present invention. As shown, an embodiment of the present invention is a case 10, a circuit board 20 mounted with a switching element 22 and a light emitting element 24, which is built in the case 10, the power is turned on and off And a button 30 provided inside the case 10 so as to be located in front of the circuit board 20 and having a display portion 32 formed thereon for transmitting the light of the light emitting element 24, and the button 30. It is coupled to the inner surface of the button 30 between the circuit board 20 and the peripheral portion is configured to include a pusher 40 formed to integrate a plurality of elastic pieces 42.

The case 10 is configured in a cylindrical shape with the front and rear ends opened. The support jaw 12 protrudes inwardly on the inner circumferential surface of the case 10, and the free end side of the elastic piece 42 of the pusher 40, which will be described later, on the upper surface of the support jaw 12 of the case 10. Point contact is supported by 42p.

The circuit board 20 is equipped with a switching element 22 (specifically, a tact switch) at a central portion thereof, and a light emitting element 24 (ie, a light emitting diode) is mounted at a position outside the switching element 22. The switching element 22 and the light emitting element 24 of the circuit board 20 are electrically connected to an external control device (not shown).

The button 30 is provided inside the case 10 to be located at the front of the circuit board 20. The display part 32 which transmits the light of the light emitting element 24 is formed in the surface of this button 30. FIG. In addition, the button 30 is configured in a circular shape to be embedded in the cylindrical case 10, the outer button of the circular button 30 is fitted into the insertion hole 12a formed in the support jaw 12 of the inner peripheral surface of the case 10 The stopping portion 34 extends downward. That is, the locking portion 34 is provided spaced apart at regular intervals along the outer periphery of the circular button 30, the lower end portion of the locking portion 34 around the insertion hole 12a of the support jaw 12 of the case 10 Since the locking protrusion 34a is caught on the part, the button 30 may be moved back and forth without being separated from the cylindrical case 10.

The pusher 40 includes a push part 44 formed in a circular shape so as to be embedded in the case 10, and a proximal end portion is integrated with the outer circumferential surface of the push part 44, and is disposed at predetermined intervals along the outer circumferential surface of the push part 44. It consists of a plurality of elastic pieces 42. Since the pusher 40 is made of a transparent synthetic resin, the light of the light emitting device 24 may be emitted to the light-transmissive display unit 32 of the button 30. In addition, since the push part 44 and the elastic piece 42 of the pusher 40 are integrally molded with such a transparent synthetic resin, the elastic piece 42 can have an appropriate elastic force. Since the pusher 40 may be formed by adopting a resin of a suitable material in order to have the elastic piece 42 to have elasticity, description of specific components of the pusher 40 will be omitted.

Accordingly, when the user presses the button 30 and the pusher 40 is pressed together, the pusher 44 and the button 30 of the pusher 40 are pressed while being rotated in one direction along the circumferential direction. As the pusher 40 is released, the pusher 44 and the button 30 of the pusher 40 may be rotated in opposite directions along the circumferential direction by the elastic force of the elastic piece 42. .

According to the present invention having such a configuration, when the user presses the button 30, the push piece 44 is pressed at the same time as the elastic piece 42 of the pusher 40 is pressed, thus the center of the pushed portion 44 The push projection of the squeezes the switching element 22 (that is, the tact switch) to turn the switching element 22 on. Then, a signal is input to a control circuit electrically connected to the circuit board 20 so that the light emitting element 24 (that is, the light emitting diode) emits light, and the light emitting element 24 is formed by the display unit 32 formed on the surface of the button 30. Lights up to indicate that the elevator switch is in operation.

Next, when the user releases the pushed state of the button 30, the pusher 44 of the pusher 40, the plurality of elastic pieces 42 provided on the outer periphery is returned upward by the elastic force of the pusher 40 And the button 30 can be retracted to return to the original position.

Therefore, the present invention is a structure that releases the pressed state of the button 30 by the plurality of elastic pieces 42 integrated on the outer periphery of the pusher 44 of the pusher 40, and unlike the prior art, the button ( Since the pusher 40 and the return spring do not need to be separately provided to return the 30 to its original position, there is an advantage in that the number of parts is reduced. In addition, there is an advantage that productivity is improved.

In addition, the present invention has the advantage that the service life of the product is extended because it takes a relatively small number of parts compared to the prior art, and the phenomenon such as the spring is prevented from swiveling or sitting down in the long-term use, thereby improving the reliability of the product There are advantages to it.

On the other hand, according to the present invention, the leading end of the elastic piece 42 integrated with the pusher 44 of the pusher 40 becomes a free end. In addition, the elastic piece 42 of the pusher 40 is integrated so as to be inclined downward from the upper surface of the pusher 44 so that the free piece side of the elastic piece 42 is disposed on the support jaw 12 of the inner circumferential surface of the case 10. The point contact portion 42p which is in contact is formed.

Accordingly, when the user presses the button 30 and the pusher 40 is pressed together, the pusher 44 and the button 30 of the pusher 40 are pressed while being rotated in one direction along the circumferential direction. As the pusher 40 is released, the pusher 44 and the button 30 are rotated in opposite directions along the circumferential direction by the elastic force of the elastic piece 42 of the pusher 40 so that the pusher 40 can be returned. do.

As such, the button 30 is pressed while being rotated in one direction and returned to its original position while being rotated in another direction, thereby preventing the button 30 from being pressed and released by foreign matters caught between the button 30 and the case 10. You do not receive it.

In other words, when the elevator switch is used for a long time, foreign matter such as dust accumulates between the outer circumferential surface of the button 30 and the inner circumferential surface of the case 10, and thus, the button 30 is stiff and hard to be pressed by the foreign matter. May occur and may not be properly returned to its original position. That is, since the friction force between the button 30 and the switch case 10 is increased and stiffened by the foreign matter, the pressing operation and the home position return operation of the button 30 may not be properly performed.

However, in the present invention, since the button 30 is pressed while being rotated in one direction and returned to its original position while being rotated in the other direction, frictional force due to foreign matter between the button 30 and the switch case 10 is further reduced. In addition, the button 30 is stiff so that the pressing operation of the button 30 is not smoothly performed, as well as preventing the button 30 from properly returning to the original position.

For example, in the present invention, since the friction force due to the foreign matter is significantly lowered while the button 30 is pressed while being rotated or returned to its original state, the pressing of the button 30 due to the foreign matter accumulated between the button 30 and the switch case 10 is performed. There is no case where the operation and the return operation are interrupted.

In addition, since the button 30 is rotated and returned to its original position, a tilting phenomenon in which one side of the button 30 is pressed and not properly returned can be prevented.

In other words, when pressing the button 30 and then releasing the pressed state, the button 30 should be returned to its original position, and the button 30 is caused by foreign matter such as dust accumulated between the button 30 and the switch case 10. A tilting phenomenon may occur in which either side of the 30 is not returned to the pressed state.

By the way, in the case of the present invention, since the foreign matter is pushed in the direction of rotation while the button 30 is rotated and returned to its original position, the frictional force is reduced, so that either side of the button 30 is pressed and pinched by the switch case 10. There is an effect to prevent the tilting phenomenon to be left in advance.

Another reason for the present invention is to reduce the frictional force caused by the foreign matter to facilitate the pressing and returning operation of the button 30 and to prevent the tilting phenomenon. The pusher 44 of the pusher 40 is provided. The front end of the elastic piece 42 integrated into the free end becomes a free end, and the elastic piece 42 is integrated so as to be inclined downward from the upper surface of the pusher 44 so that the switch case 10 is located on the free end side of the elastic piece 42. This is because the point contact portion 42p in point contact with the support jaw 12 on the inner circumferential surface is formed.

That is, when the button 30 is pressed, the push part 44 may be rotated by the inclined elastic piece 42 of the pusher 40, and the point contact part 42p on the free end side of the elastic piece 42 may be rotated. Is the rotational support point of the pusher 44, the pusher 44 and the button 30 are pushed while being rotated in one direction, while the pusher 44 and the button 30 are released when the button 30 is released. ) Can be returned to its original position while rotating in the other direction, thereby reducing the frictional force caused by the foreign matter between the button 30 and the switch case 10 to smoothly push the button 30 and the home position return operation. At the same time it can prevent the tilting phenomenon.

On the other hand, according to the present invention, the pusher 44 of the pusher 40 is provided so that a separate reinforcing stone piece 44a protrudes downward on the end side opposite to the free end of the elastic piece 42.

Accordingly, when the elastic piece 42 is pressed, the opposite side of the free end of the elastic piece 42 (that is, the base end of the elastic piece 42) is reinforced by the reinforcing protrusion piece 44a, so that the elastic piece 42 is removed. There is an effect of preventing the phenomenon that the proximal end of the elastic piece 42 is easily cut from the push part 44 by the pressing force. In addition, the lower end of the reinforcing stone piece 44a is in contact with the support jaw 12 of the inner circumferential surface of the switch case 10, so that the elastic piece 42 of the button 30 and the pusher 40 is excessively pressed by the force. There is also an effect of preventing the phenomenon that the proximal end of the elastic piece 42 is easily cut.

That is, when the push part 44 and the elastic piece 42 which are the main parts of the pusher 40 are integrally formed with synthetic resin, and the elastic piece 42 is excessively pressed, the proximal end of the elastic piece 42 is the push part 44. It can be cut in), the reinforcing stone piece (44a) is caught on the support jaw 12 of the inner circumferential surface of the case 10 to limit the push portion 44 of the pusher 40 is further lowered, thereby, The elastic piece 42 of the pusher 40 is excessively pressed to prevent the phenomenon that the base end of the elastic piece 42 is broken. This reinforcing stone piece (44a) will eventually be said to function as a break prevention stopper to prevent the force applied to the proximal end of the elastic piece 42 to act excessively.

In addition, the button 30 is formed in a circular shape so as to correspond to the pusher 44 of the pusher 40, and the insertion hole formed in the support jaw 12 of the inner circumferential surface of the case 10 in the outer portion of the button 30 ( 12a) is formed so that the engaging portion 34 to be caught is extended downward, the width (D) of the insertion hole (12a) is configured to be relatively larger than the width (d) of the locking portion 34 of the button (30). As a result, a clearance capable of rotationally moving in the circumferential direction of the engaging portion 34 of the button 30 is ensured.

Due to the structure that secures the clearance, there is an effect of more reliably ensuring that the push portion 44 of the button 30 and the pusher 40 is pressed or released while rotating in the circumferential direction.

On the other hand, Figure 7 is an exploded perspective view of another embodiment of the present invention, Figures 8 and 9 are longitudinal cross-sectional view showing the operation state of the main part of FIG. According to another exemplary embodiment of the present invention according to FIGS. 7 to 9, the case 10 is configured in a square shape, and the pusher 50 has a square plate-shaped push part 54 to be embedded in the rectangular case 10. And a plurality of elastic pieces 52 having a proximal end integrated with the front, rear, left, and right outer portions of the push part 54.

In addition, the front end portion of the elastic piece 52 is composed of a free end, the support jaw 12 protrudes inward to the inner circumferential surface of the case 10 in which the pusher 50 is embedded, the elasticity of the pusher 50 The piece 52 is integrated so as to be inclined downward from the upper surface of the pusher 54 so that the point contact portion 52p which is in point contact with the support jaw 12 of the inner circumferential surface of the case 10 on the free end side of the elastic piece 52 is provided. Is formed.

Another embodiment of the present invention is similar to the function and effect of the embodiment of the present invention due to the functions and effects of the above configuration, duplicate description thereof will be omitted.

In addition, according to another embodiment of the present invention, the opposite end of the free end of the elastic piece 52 is formed to be integrated into the four parts of the rectangular push portion 54 of the button 30, the rectangular push portion 54 A reinforcing protrusion 52a is further provided at a portion adjacent to the free end portion of the elastic piece 52 opposite to the free end portion (that is, the base end of the elastic piece 52).

Such reinforcing protrusions 52a can exert a strength reinforcing effect of preventing the elastic piece 52 of the pusher 50 from being excessively pressed and cut.

In addition, according to another embodiment of the present invention, the stop stone piece 54a in contact with the support jaw 12 of the inner circumferential surface of the case 10 protrudes downward from the bottom of the pusher 54 of the pusher 50.

When the stop stone piece 54a presses the button 30, excessive force is applied to the base piece of the elastic piece 52 of the pusher 50 to prevent the base piece of the elastic piece 52 from being broken at the push part 54. It works. That is, when the push part 54 and the elastic piece 52 which are the main parts of the pusher 50 are integrally formed with synthetic resin, and the elastic piece 52 is excessively pressed, the proximal end of the elastic piece 52 is the push part 54. It can be cut in the), the stop stone piece (54a) of the bottom of the rectangular push portion 54 is caught by the support jaw 12 of the inner peripheral surface of the case 10 to further prevent the push portion 54 is lowered, For this reason, the elastic piece 52 of the pusher 50 is excessively pressed, and there exists an effect which prevents the base end part of the elastic piece 52 from breaking.

The present invention described above is not limited to the above-described embodiments and the accompanying drawings, and various substitutions, modifications, and changes are possible in the art without departing from the technical spirit of the present invention. It will be apparent to those of ordinary knowledge.

As described above, the elevator switch according to the present invention has the following effects.

First, it is a structure that releases the pressed state of the button by a plurality of elastic pieces integrated on the outer periphery of the pusher of the pusher, and does not need to separately provide a pusher and a return spring to return the button to its original position. The effect is to reduce the number.

Secondly, since it is not necessary to properly arrange the plurality of springs in place, there is an effect that the manufacturing operation is easy and the productivity is further improved.

Third, the present invention has the effect of extending the life of the product because it takes a relatively small number of parts compared to the prior art, and because the phenomenon such as the spring is shifted in the correct position or slumping is prevented when using for a long time, thereby improving the reliability of the product It can be effective. Meanwhile, the above effects can be expected in the other embodiments of the present invention as well.

Fourth, the present invention, when the user presses the button, the button and the pusher of the pusher is pressed while rotating in one direction along the circumferential direction, while the push of the pusher by the self-elastic force of the elastic piece integrated in the pusher as the button is released It is a structure that the part and the button can be returned while rotating in the opposite direction along the circumferential direction.The button is pressed while being rotated in one direction and returned to its original position while being rotated in the other direction, so that the frictional force caused by the foreign matter between the button and the switch case is relatively Since it is further reduced, the button is stiff, which prevents the button from being pressed smoothly, and also prevents the button from being properly returned to its original position.

Fifth, since the present invention reduces the friction force as the button is returned to its original position while rotating the button, there is an effect that can be prevented in advance the tilting phenomenon that one of the buttons are left pressed by the switch case.
