As shown in FIGS. 5A and 5B, the internal structure of each of the operation scaffolds 41 is provided to be spaced apart from the lower support frame 50 and the lower support frame 50 to emit internal lights to the outside. The footrest 57 is installed near the center of each corner of the rim between the lower support frame 50 and the operation footrest 57 to support the operation footrest 57 from the frame 50. The elastic part 55 to give elasticity in the vertical operation and the left and right of the elastic part 55 on the frame 50 so as not to fall below a certain value when the operating step 57 is pressed. It is composed of a safety unit 56 to determine the operation limit, and the non-contact detection unit (52, 53, 54) installed to the right or left of the elastic portion 55 to detect the pressing of the operation step (57).

Unexplained reference numeral 58 denotes a cover which prevents exposure to the outside, and 59 denotes an operation substrate on which various electronic components are mounted to exchange signals with the flexible board period and the scaffolding device.

Here, the elastic part 55 may employ a coil spring or a rubber spring, and when the coil spring is adopted, the user's foot motion sensitivity may be more effectively enjoyed than the rubber spring.

As shown in FIG. 6A, the non-contact detection units 52 and 54 include an optical sensor unit including a light emitting element unit 52-1 and a light receiving element unit 52-3 installed on the lower support frame 50.

It is composed of a phototransistor, the blocking unit is sufficient if it is an impermeable material that can block the optical signal. Detailed configuration thereof is already well known technology, and thus a detailed description thereof will be omitted.

In addition, the light sensor further includes a resilient sensor protection member 53 which is installed in contact with the blocking part 54 on the upper part of the optical sensor 52 and pressed when the blocking part 54 is lowered. The sensor protection member 53 may be made of a kind of rubber or silicon.

The operation of the scaffolding device configured as described above will be described with reference to FIGS. 6A and 6B.

FIG. 6A is a view showing an operation when the operating step is not lowered, and FIG. 6B is a view showing an operation when the operating step is lowered.

Referring to FIG. 6A, when the operation footrest 57 does not lower, while the coil spring 55 supports the operation foothold 57 as it is, the safety part 56 is slightly spaced apart from the lower surface of the operation foothold 57. The upper portion of the cut-off portion 54 of the non-contact sensing portion is slightly spaced apart from the lower surface of the operating scaffold 57 and the light emitting element portion 52-1 and the light receiving element portion 52-3 of the optical sensor portion. There is no blocking part inserted between them.

Accordingly, an optical signal is transmitted from the light emitting element unit 52-1 of the optical sensor unit 52 to the light receiving element unit 52-3 so that the light receiving element unit 52-3 outputs the detected optical signal to a circuit unit (not shown). ), And the circuit unit compares the incoming optical signal with a threshold to determine that the operation scaffold is not lowered when the threshold is greater than or equal to the threshold.

Referring now to FIG. 6B, when the operation footrest 57 is lowered, the coil spring 55 is compressed to the length of the safety part 56 by the pressing of the operation footrest and the blocking portion 54 of the non-contact sensing part operates. As the footrest 57 is pressed, the sensor protection member of the optical sensor portion is pressed, and the convex insertion portion of the blocking portion at this time is pushed between the light emitting element portion 52-1 and the light receiving element portion 52-3.

Accordingly, since an optical signal is hardly transmitted from the light emitting element unit 52-1 of the optical sensor unit 52 to the light receiving element unit 52-3, the light receiving element unit 52-3 transmits the detected optical signal to the circuit unit ( Not shown), and the circuit unit compares the incoming optical signal with a threshold to determine that the operation scaffold is lowered below the threshold.

In this way, by blocking the optical signal of the optical sensor unit as the operating scaffold is pressed, the intensity of the received signal can be detected to detect that the operating scaffold is pressed.

On the other hand, the non-contact detection unit may be provided with one or two or more at each corner of the frame in order to properly detect the smooth up and down movement of the operation scaffold 57.

In another embodiment of the present invention, the fluorescent light of the scaffold may employ a light emitting diode instead of a conventional fluorescent lamp to emit a different light for each operating scaffold to enjoy a visual effect.

As described above, the scaffolding device according to the present invention employs a non-contact detection unit (ultraviolet light sensor) instead of a conventional contact switch (silicon rubber switch), thereby improving the life of the operation switch infinitely and increasing the accuracy of motion detection. .

In addition, compared to the conventional scaffolding device, the product of the present invention not only has the reliability of operation but also the cost saving effect due to the simplification of the assembling process. It has an effect.
