Description

Elevator switch with improved light emitting means {A switch for elevator}

The present invention relates to an elevator switch with improved light emitting means, and more particularly, since light emitted from an LED fixed to a PCB substrate is emitted to the outside through several light emitting parts protruding from the back of the knob, light scattering is effectively increased. While the projected light is dispersed, the light emitting means for identifying a more clear elevator switch button from the outside relates to an improved elevator switch.

In general, elevators are installed in high-rise buildings, apartments, or industrial sites, and are widely used as a means of transporting people or cargo up and down.

In addition, a separate operation panel is provided inside the elevator, and the operation panel is equipped with a switch in which the number of floors is displayed.

In addition, the elevator push button is equipped with a tact switch and LED is a power switch on / off operation at the same time a plurality of push pins to press and press the PCB board having a plurality of screw holes and the plate spring located above the tact switch It is a general configuration that consists of a frame having a built-in slider upright, a dial positioned on the slider to display the number of layers, and a guide body coupled to the frame with the dial interposed therebetween.

 Meanwhile, as shown in FIG. 1, a conventional elevator switch structure is accommodated in a lower frame having an open upper surface, a lower frame, a circuit board on which a tact switch is mounted, and a buffer member fixed to a lower frame and contacting the tact switch, and a lower frame. And a spring provided between the upper frame and the lower frame and the upper frame in which the hooks necessary for coupling are formed.

In the above-described configuration, a hook groove is formed on the side of the lower frame, and a spring nose projection is formed on the bottom surface thereof.

In the next circuit board, a light emitter which emits light by a signal generated when the tact number position is pressed and a signal output line for outputting the above-described signal to the outside are mounted.

Next, the shock absorbing member is made of an elastic bar, the inner buffer bar is formed to be separated from each other, the outer side is a configuration in which the coupling hole coupled to the spring fixing projections, perforated,

Next, the upper frame is formed with a cushioning member push projection for transmitting the external pressure to the buffer member.

Therefore, when an external force is applied to the upper frame, the upper frame is pressed into the lower frame by the elasticity of the spring and at the same time the buffer member pressing protrusion of the upper frame presses the buffer bar, and the tact switch is pressed by the buffer bar. The light emitter emits light, and the signal is output from the signal output line.

However, in this case, there is a problem in that the light transmittance emitted from the light emitter is transmitted to the outside, which is not clearer.

In addition, according to the conventional elevator switch structure because the buffer member is fixed to the lower frame by the spring fixing projections to operate the tact switch, there is a problem that inhibits the feeling of press because more than the external pressure required to be applied to the buffer subsidiary. .

In addition, such a method increases the assembly time due to the addition of a component such as a shock absorbing member, as well as an increase in the productivity and the inconvenience of work because the worker must assemble.

The present invention has been made to actively solve the above problems, while effectively scattering the light due to the light emitted from the LED fixed to the PCB substrate to the outside through several light projections protruding on the back of the knob It is an object of the present invention to provide an elevator switch having improved light emitting means capable of widely distributing the projected light to identify an elevator switch button that is clearer from the outside.

As a means for achieving the above-described technical problem, to form a plurality of light transmitting parts protruding on the back of the knob, the light transmitting part can receive a light emitted from the LED assembled on the PCB substrate to be widely emitted to the outside, the back of the knob Form a push switch that can touch the sensing unit formed on the PCB substrate in the center, forming a fixture for supporting the spring at each corner of the knob, and forming a locking jaw at the bottom of the knob to be assembled to the main body The light emitting means is improved elevator switch.

The present invention not only can reduce the material cost and assembly cost by implementing the structure simplification and ultra-slim, but also has the characteristics of reducing labor costs and improving productivity.

In addition, since light is emitted to the outside through several light emitting parts protruding from the back of the knob, the scattered light is widely distributed while effectively increasing light scattering, thereby making it possible to check the elevator switch button more clearly from the outside.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings so that those skilled in the art can easily carry out the present invention. As those skilled in the art would realize, the described embodiments may be modified in various different ways, all without departing from the spirit or scope of the present invention.

First, the present invention forms a plurality of light transmitting parts 13 protruding on the back surface of the knob 11 as shown in FIGS. 1, 2, and 4.

At this time, the light transmitting portion 13 is a configuration in which the protrusions having the shape of an inverted triangle are connected to each other. In addition, the function of the light-transmitting unit 13 is a configuration that can be more widely received by the light flowing from the outside.

Here, the light transmitting portion 13 is a configuration that can be widely emitted to the outside by receiving the light emitted from the LED 17 assembled to the PCB substrate 18.

Meanwhile, a push switch 14 may be formed at the center of the rear surface of the knob 11 to touch the sensing unit 24 formed on the PCB substrate 18.

In addition, at each corner of the knob 11, a fixture 15 for supporting the spring 20 is formed, and a locking jaw 21 is formed below the knob 11 to be assembled to the main body 10. to be.

Here, the portion of the locking jaw 21 formed in the lower portion of the knob 11 is configured to be fixed to the locking hole 25 of the main body 10 as shown in Figure 1 and 2, this method is the same as the conventionally known method To similar.

In addition, the cover 12 for supporting the PCB substrate 18 and being fixed is configured to be integrally assembled with the main body 10. In this case, the fixing pin 22 formed at both sides of the cover 12 has a main body ( 10) It is a configuration that is fixed while being inserted directly into the locking groove 23 formed on both upper sides.

Therefore, when the user presses the knob 11, the push switch 14 part touches the sensing unit 24 so that an external power source emits the LED 17 connected to the PCB substrate 18.

Then, the pressure applied to the push switch 14 is converted into an electrical signal by the sensing unit 24 and the converted signal is transmitted to the elevator control unit to drive the corresponding parts and mechanisms.

At this time, the switch pressed by the user is irradiated with light from the LED (17) to confirm that the elevator is moving to the floor, and when the arrival to the floor, the light irradiated from the LED (17) is stopped to inform that the floor has arrived. .

Here, the light emitted from the LED 17 fixed to the PCB substrate 18 is emitted to the outside through several light projections 13 protruding from the back of the knob 11, thereby effectively increasing the scattering of the light while projecting You can see the brighter light from outside by dispersing the light.

As described above, the present invention not only can reduce the material cost and the assembly cost by implementing the structure simplification and ultra-slim, but also has the characteristics of reducing labor costs and improving productivity.

In addition, since light is emitted to the outside through several light emitting parts protruding from the back of the knob, the scattered light is widely distributed while effectively increasing light scattering, thereby making it possible to check the elevator switch button more clearly from the outside.
