KR101330982B1 - Elevator switch having improved restoration elasticity of upward and downward operation - Google Patents

Abstract

The present invention is an elevator switch improving the restoration elasticity of upward and downward operation that forms a main gap of a constant gap space on the top of three thin main bands so that the bands are formed on a bottom end of a border ring of a pusher attached to the bottom of a button. The switch forms a convex protrusion on the bottom middle of the main bands so that the button and the pusher move downwardly while the main bands move toward to the constant gap space by three convex protrusions attached to a top surface of acircuit board when the button is pushed. When the button is released, the button and the pusher return to the original state while the main bands which move toward the constant gap space of the bottom end of the border ring move downwardly by self-elasticity.

Description

Elevator switch having improved restoration elasticity of upward and downward operation

The present invention is to press the button of the switch on, and when the button is released when the button is released, the elevator switch to the up and down operation of the button accurately and smoothly, the elevator can be used for a long time to improve the resilience of the up and down operation It is about a switch.

Conventional elevator switch has a large number of parts and complicated assembly process by using a coiled spring mainly as a restoring device for operating the button upward when the button is released while pressing the button.

In order to improve this, in Patent No. 0871879, the pusher coupled to the lower part of the button and operating upward and downward with the button and turning on the switching element protruding in the center of the upper surface of the circuit board downward along the outer circumferential surface of the disc-shaped push part 44. A plurality of inclined elastic pieces

형으로 형성시킨 하향 경사진 복수개의 탄성편(42)에 의존함으로써 상, 하향 작동시 한쪽으로 편중이 되어 작동상태가 원활하지 못한 결점이 있었다.When the pusher 40 is pressed by arranging the 42 at predetermined intervals, the pusher 40 and the button 30 are pressed while partially rotating in one direction along the circumferential direction and push when the pusher 40 is released. Part 44 and button 30 is to restore the part while rotating in the opposite direction along the circumferential direction, the resilient restoration of the pusher 40 and the button 30 is operated in one direction rotation and the opposite direction rotation As the device has a complicated up and down operation, there is a risk of failure, and the restoring elasticity during the up and down operation is applied to the outer circumferential surface of the push unit 40.

By relying on the plurality of downwardly inclined elastic pieces 42 formed in a mold, there is a defect in that the operation state is not smooth due to the bias toward one side during the up and down operation.

In the elevator switch, the pusher and the button can be operated up and down without biasing to one side, and the body can be operated evenly up and down without using any parts. We needed a way to use it.

In the present invention, by using the edge ring of the pusher attached to the lower part of the button up and down operation of the button, three thin peripheral bands of a certain thickness are formed on the lower end of the ring so that the upper part of the three thin peripheral bands has a constant space between them. By forming a peripheral gap and forming a convex protrusion in the middle of the bottom of the three thin peripheral bands and pressing the button, the three thin peripheral bands at the lower end of the pusher's edge ring are connected by the three convex protrusions that are in contact with the upper surface of the circuit board. The button and the pusher are downward while the three thin peripheral bands are raised to the space between the upper peripheral gaps, and when the button is released, the three gaps are separated by the three convex protrusions. The three thin bands that have been raised to space are lowered to their own elasticity, and the buttons and pushers are upward and returned to their original positions.

The present invention uses the edge ring, which is the main body of the pusher, to operate the button up and down as three convex bands at the bottom of the ring, three peripheral gaps at the top, and three convex protrusions at the bottom of the three thin peripheral bands. By replacing the resilient restoring operation, the up and down operation is accurate and smooth without biasing to one side, so there is no fear of failure even in long-term use.

The circuit board 50 is bonded to the upper surface of the inner bottom plate of the case 40, and the pusher 20 is attached to the bottom of the upper periphery frame 30 by the buttons 10 attached to the bottom by three protruding through holes 21a at the edges. Three hanging belts 11 extending downward in the outer circumference of the button 10 are coupled to be caught by the lower inner end of the upper periphery frame 30 as the end projections 11a so as to flow up and down in the upper periphery frame. 30 is closely inserted into the outer frame separated into a plurality of upper and lower parts of the case 40 and the upper periphery frame 40 corresponding to the upper protrusion 41a of the inner circumferential surface of the three outer frames 41 of the plurality of outer frames. An elevator switch is configured by being coupled as an unevenness to the upper grooves 32 between the three vertical poles 31 formed on the outer circumferential surface.

The elastic protrusions 23 protruding from the center of the four connecting rods 22 connected in the center direction from the edge ring 21 of the pusher 20 attached to the bottom of the button 20 are formed on the circuit board 50. The switching element 51 is turned on and off by contacting the switching element 51 protruding in the center of the upper portion by the vertical operation of the button 10.

The upper part of the three thin peripheral bands 24 of the lower end is formed as a peripheral gap 25 of the predetermined interval space so that three thin peripheral bands 24 having a predetermined thickness are formed at the lower end of the edge ring of the pusher 20. In the middle of the lower end of the three thin peripheral bands 24 at the lower end, the convex protrusions 26 having the same interstitial size of the peripheral gap 2 are formed to be the same size, and the three convex protrusions 26 of the same size are formed in the circuit. The upper surfaces of the substrates 50 are the same as each other.

When the button 10 of the elevator switch coupled as described above is pressed, the pusher 20 attached to the bottom surface of the button 10 protrudes in the middle of the three thin peripheral bands 24 at the lower end of the edge ring 21. Since the projections 26 are in contact with the upper surface of the circuit board 50, three convex projections

By 26, three thin peripheral bands 24 are upwardly spaced by the self-elasticity into the space between the upper peripheral gaps 25, while the pushers 20 are downwardly protruding below the center of the four connecting rods 22. When the elastic protrusion 23 is pressed on the switching element 51 of the circuit board 50 and releases the pressed state of the button 10, the pusher 20 is edge ring 21 by the three elastic protrusions 23. 3) The three thin peripheral bands 24, which were upwardly moved to the space between the upper peripheral gaps 25 of the lower end, are downward by the own elasticity, and the pusher 20 and the button 10 are upwardly returned.
