Description

MANUFACTURE METHOD OF ELEVATOR S LIGHT PERMEATION TYPE CONTROL BUTTON AND THEREOF

PRODUCT

Technical Field

[1] The present invention relates to a control button, which is installed in elevator to mark the running floor, or open and close the door thereof, and more particularly, to a manufacturing method of a transmissive control button for an elevator and the control button manufactured thereby, in which lights are emitted from figures and brailles formed on a push plate in order to ensure the improvement in visibility.

Background Art

[2] In general, an elevator is an apparatus for moving people or loads up and down along a pair of guide rails arranged along an internal vertical path of a building, and is mainly used for residents' easy movement in high-rise buildings.

[3] Various control panels for choosing the floor or opening and closing the door is provided on the control panel in the elevator. In such a case, when the push plate of the control button is pushed lightly, any of the switches embedded in the button case is operated on.

[4] Figures are marked on the push plate, and, at the same time, brailles for a visually impaired person are protrusively formed thereon.

[5] In addition, a light-emitting lamp is provided inside the control button, and a

transparent panel is interposed between the periphery and the edge of the push plate. In such a case, when the control button is pushed, the light-emitting lamp (LED) is switched on, and emits the light through the transparent panel, whereby permitting a controller to visually identify the lightness of the button.

[6] However, the conventional configurations of the control button has a problem in that the push plate marked by the figures does not shine brilliantly, but the circumference of the push plate is lighted hazily, such that it can not be distinctly identified.

[7] In addition, since lights are not generated from figures and brailles formed on the push plate, there are also insufficient considerations for a visually impaired person. Disclosure of Invention

[37] Then, S7, installing a printed circuit board (PCB) 12 in which a light emitting diode

(LED) 14 is embedded in the outer hull member 5 of the formed article demolded above is conducted, such that the manufacture of the transmissive control button A for an elevator in accordance with the present invention is completed.

[38] The transmissive control button for an elevator manufactured by the aforementioned manufacturing method can be largely classified as four types of embod iments.

[39] Accompanying FIGS. 4 to 7 are a plan view and a sectional view for the

transmissive control button manufactured by the present invention.

[40] Referring those figures, the push plate 2 of the transmissive control button for an elevator is formed in flat shape. FIGS. 4 and 5 illustrate the control button Al free of the gap between the push plate 2 and the outer hull member 5, and FIGS. 6 and 7 illustrate the control button Al' in which the transmissive part 50 is formed by the gap between the push plate 2 and the outer hull member 5.

[41] Thus, light-emitting can be performed in the control button Al and Al' by the

transmissive part 50 formed at the periphery of the push plate 2.

[42] Accompanying FIGS. 8 to 11 are a plan view and a sectional view for other

embodiment of a transmissive control button manufactured by the present invention.

[43] Referring those figures, the push plate 2 of the transmissive control button for an elevator is formed in mesh shape. FIGS. 8 and 9 illustrate the control button A2 free of the gap between the push plate 2 and the outer hull member 5, and FIGS. 10 and 11 illustrate the control button A2' in which the aforementioned transmissive part 50 is formed between the push plate 2 and the outer hull member 5.

[44]

[46] Referring those figures, some part of the push plate 2 of the transmissive control button for an elevator is formed in flat shape, and other part thereof is formed in mesh shape. FIGS. 12 and 13 illustrate the control button A3 free of the gap between the push plate 2 and the outer hull member 5, and FIGS. 14 and 15 illustrate the control button A3' in which the aforementioned transmissive part 50 is formed between the push plate 2 and the outer hull member 5.

[47] Accompanying FIGS. 16 to 19 are a plan view and a sectional view for still another embodiments of a transmissive control button manufactured by the present invention.

[48] Referring those figures, the push plate 2 of the transmissive control button for an elevator is formed in concavely recessed shape. FIGS. 16 and 17 illustrate the control button A4 free of the gap between the push plate 2 and the outer hull member 5, and FIGS. 18 and 19 illustrate the control button A4' in which the transmissive part 50 is formed between the push plate 2 and the outer hull member 5.

[49] The thus manufactured transmissive control button A1-A4' for an elevator is inserted to be engaged with the inner side of the frame 3 inserted into a connection hole (not shown) provided in suitable position of the control panel (not shown), and then fastened thereto, and thereafter connecting the power to the printed circuit board (PCB) 12, whereby the installation is completed.

[50] Then, when a user push the push plate 2, the inner light emitting lamp (LED) 14 is enlightened therein, and the light produced therefrom is emitted outwardly by passing through the synthesis resin forming the figures 22 and the brailles 24 of the push plate 2, thereby allowing more brighter emission of light.

[51] In the transmissive control button Al for an elevator depicted in FIGS. 4 and 5, the light emitting can be performed in the figures 22 and the brailles 24 of the push plate 2. In the transmissive control button Al' for an elevator depicted in FIGS. 6 and 7, in which the transmissive part 50 is formed between the push plate 2 and the outer hull member 5, the light emitting can be performed through the figures 22, the brailles 24, and the transmissive part 50.

[52] On the other hand, in the transmissive control button A2 for an elevator manufactured by the process of FIGS. 8 and 11, since the light emitting can be also performed through fine pores of the mesh shape of the push plate 2, as well as in the figures 22 and the brailles 24 of the push plate 2, the front surface of the push plate 2 can be more luminous.

[53] In addition, in the transmissive control button A2 for an elevator, the light emitting can be performed in the push plate 2, the figures 22, and the brailles 24. in the transmissive control button A2' for an elevator, the light emitting can be performed through the push plate 2, the figures 22, the brailles 24, the transmissive part 50, and the front surface of the push plate 2.

[54] On the other hand, in the transmissive control button A3 for an elevator manufactured by the process of FIGS. 12 and 15, since the light emitting can be also performed through fine pores of some mesh shape of the push plate 2, as well as in the figures 22 and the brailles 24 of the push plate 2, the control button A3 can be more luminous.

[55] In addition, in the aforementioned transmissive control button A3 for an elevator depicted in FIGS. 12 and 13, the light emitting can be performed in some part of the push plate 2, the figures 22, and the brailles 24. In the transmissive control button A3' for an elevator depicted in FIGS. 14 and 15, the light emitting can be performed through some part of the push plate 2, the figures 22, the brailles 24, and the transmissive part 50.

[56] On the other hand, in the transmissive control button A4 manufactured by the

process of FIGS. 16 and 19, since the push plate 2 is recessed shape, although it comes into contact with any material body, it does not work so as to prevent unnecessary mis- operation, and at the same time, the figures and the brailles of the push plate 2 can be light-emitted, thereby allowing more brighter luminance.

[57] In addition, in the aforementioned transmissive control button A4 for an elevator depicted in FIGS. 16 and 17, the light emitting can be performed in the push plate 2, the figures 22, and the brailles 24. In the transmissive control button A4' for an elevator depicted in FIGS. 18 and 19, the light emitting can be performed through the push plate 2, the figures 22, the brailles 24, and the transmissive part 50.

[58] Thus, although the invention has been shown and described with respect to

exemplary embodiments thereof, it should be understood by those skilled in the art that the foregoing and various other changes, omissions and additions may be made therein and thereto, without departing from the spirit and scope of the invention.
