Abstract

PURPOSE: A button structure of an image display apparatus is provided to effectively control the image display apparatus without using any spring. CONSTITUTION: A button of an image display apparatus comprises a square boundary frame(160), four elastic ribs(110), each for forming a closed loop inside the boundary frame(160), a circular inner frame(170) connected to the elastic ribs(110), a front-to-rear location setting protrusion(120), four front-to-rear and right-to-left location setting protrusions(130), and four contact protrusion bosses(140). The boundary frame(160) is fixed to a cabinet by using mounting holes at its corners. The elastic ribs(110) generate restoring force when the button is pressed. The front-to-rear location setting protrusion(120) measures a distance between the button(100) and a PCB. The front-to-rear and right-to-left location setting protrusion(130) sets the location of the button accurately. The contact protrusion bosses(140) match contact protrusions of the PCB to perform accurate control.

Description

Button structure of video display device {A BUTTON STRUCTURE OF VIDEO DISPLAY APPLIANCE}

The present invention relates to a button structure of a video display device, and more specifically, to a control section for controlling a video display device, by improving an existing button structure using an interlocking relationship between a plurality of different types of components. The present invention relates to a button structure having a structure that not only realizes the same function but also additionally obtains design beauty.

Conventionally, the button structure of such a video display device has generally controlled the video display device by bringing the contact terminal of the button structure into contact with the printed circuit board of the control section. The button structure of the video display device is shown in FIG. 1. According to FIG. 1, however, this button structure has a button 1, a cabinet 2, a spring 3 and a control printed circuit board 4 secured by a latch 5 and latched in an inoperative state. The button fixed by means of the pressing operation and the terminal of the button in contact with the printed circuit board to control the video display device and takes the operation method of returning to its original position by the spring force of the spring. This button structure was forced to adopt a spring component as an essential component for the operation and release of the button. This hinders the simplification of the button structure and the cost reduction, and the assembly has to be carried out with careful attention to the assembly, since the spring must be assembled in the correct position.

In addition, a button structure of a video display device having a spring-free configuration has been proposed. This button structure is shown in FIG. According to FIG. 2, this button structure is provided between a first rectangular button 11a having an approximately rectangular circumferential edge and a first elastic rib 15a forming a closed loop from the circumferential edge to an inside thereof, between the substantially rectangular circumferential edge and the edge thereof. And a second button 11b having a second elastic rib 15b for connecting, and a cabinet 12 in which the first button and the second button are fixed, and a portion of the first button is formed at the edge of the second button. Overlapping and fixed to each other, in operation of the first button, the elasticity of the first elastic rib is transmitted to the second elastic rib due to the first button being partially fixed to the second button, and such elastic force is transmitted to the first and second It takes a way to regulate the operation of the button by being counter-repelled due to the button being fixed to the cabinet. Although such a button structure has the effect of eliminating the spring element, the above-mentioned effect can be achieved only by organically connecting two buttons and their respective elastic ribs, and thus, the configuration and manufacturing thereof are rather complicated.

Accordingly, an object of the present invention is to solve the above-mentioned disadvantages of the prior art, and to provide a button structure of an image display device having an integrated structure that can effectively control the image display device without using a spring.

1 shows a button structure of the prior art of the present invention, and FIG. 1 shows a button structure with a spring element.

Figure 2 is a view showing another prior art button structure of the present invention, a button structure of the configuration excluding the spring element, unlike FIG.

3 is a plan view showing the button structure of the video display device of the present invention, including a cross section taken along line A-A and line B-B;

In order to achieve this object, the button structure of the video display device of the present invention includes a button having elastic ribs, front and rear positioning projections, front and rear positioning projections and bosses, a cabinet for mounting the buttons, and a contact projection. And a control printed circuit board having a control panel, and at the time of operation of the button, the front and rear positions are primarily set by the front and rear positioning projections, and the top, bottom, left and right positions of the buttons are secondarily determined by the front and rear positioning projections. And the contact projection of the control printed circuit board is inserted into the boss of the button at the position, and the function is returned to the original position by the repulsive force of the elastic rib.

According to a preferred embodiment of the present invention, the button is composed of a substantially square border and a circular frame therein, each of the edge edge is provided with a linear elastic rib forming a closed loop inside the corner, each elastic rib and the circular The frames of are interconnected.

According to a preferred embodiment of the present invention, the elastic ribs, the front and rear positioning projections, the front and rear positioning projections and the boss are integrally formed.

According to a preferred embodiment of the present invention, the front and rear left and right positioning projections and bosses are each composed of four.

Hereinafter, with reference to the accompanying drawings will be described in more detail the button structure of the video display device of the present invention.

1 and 2 show a button structure of the prior art as described above, FIG. 1 is a button structure with a spring element, and FIG. 2 is a button structure without the spring element.
