Cabinet concealment device

Abstract

This invention relates to a cabinet-mounted shielding device, comprising: a cabinet with two side panels, the two side panels being separated by a partition to form an accommodating space; a shielding plate sliding up and down between the two side panels; an actuation unit generating a magnetic force when energized, normally magnetically securing the shielding plate; and an actuation unit de-energizing itself upon receiving a control signal, thus releasing the shielding plate and allowing it to fall freely; a dynamic sensing unit detecting the position of the cabinet, and outputting the control signal to the actuation unit when the cabinet tilts beyond a safe angle during shaking; and a power supply unit providing the necessary power for operation. This allows the shielding plate to be quickly lowered during an earthquake to prevent books from falling and causing danger.

Claims

1. A cabinet concealing device, comprising: a cabinet having a side panel on each of its two sides, and a plurality of partitions between the two side panels to divide the interior of the cabinet into at least one accommodating space; at least one concealing plate disposed between the two side panels, the concealing plate sliding up and down between the two side panels; at least one actuating unit fixed to the cabinet, the actuating unit normally fixing the concealing plate to prevent it from sliding down, and upon receiving a control signal, the actuating unit releasing the fixing of the concealing plate, allowing the concealing plate to fall freely to conceal the accommodating space; and a dynamic sensing unit disposed on the cabinet, the dynamic sensing unit being signal-connected to the actuating unit, the dynamic sensing unit detecting a positional state of the cabinet, and outputting the control signal to the actuating unit when the tilt angle of the cabinet exceeds a safe angle during shaking; A power supply unit is installed in the cabinet. The power supply unit is electrically connected to the actuation unit and the dynamic sensing unit, respectively supplying the actuation unit and the dynamic sensing unit with the power required for their operation.

2. As in request item 1, the cabinet enclosure device, wherein, Each of the two side panels has a slide rail on its opposite side, and each of the two sides of the baffle has a sliding part. The two sliding parts are respectively inserted into the two slide rails and slide. Each of the two slide rails has a buffer pad at its bottom.

3. As in request item 2, the cabinet concealment device, wherein, The length of the slide rail extends downwards from the top of the accommodating space to a position between 1 / 2 and 2 / 3 of the accommodating space.

4. As in request item 2, the cabinet concealment device, wherein, The baffle is made of a magnetic material, or the inner side of the baffle is provided with a magnetic sheet made of a magnetic material. The actuation unit is an electromagnet. When the actuation unit is energized, it generates a magnetic force, which attracts the baffle or the magnetic sheet when normally energized, so that the baffle does not slide down between the two slide rails.

5. As in request item 1, the cabinet concealment device, wherein, The number of actuation units is provided in the same quantity as the number of accommodating spaces.

6. As in request item 1, the cabinet concealment device, wherein, The actuation unit is fixed to the bottom of the partition.

7. As in request item 1, the cabinet concealment device, wherein, The dynamic sensing unit is either an accelerometer or a gyroscope.

8. As in request item 1, the cabinet enclosure device, wherein, The safety angle is 5 degrees or less.

9. The cabinet enclosure device as requested in item 1, wherein, The power supply unit is equipped with a power plug for plugging into a mains outlet to output power.

10. The cabinet enclosure device as requested in item 1, wherein, The dynamic sensing unit is equipped with a control switch, a detection warning light, and a forced warning light. The control switch has options for power off, detection mode, and forced mode. When power off is selected, the dynamic sensing unit is turned off. When detection mode is selected, the actuator is normally powered on and the detection warning light is lit. When forced mode is selected, the actuator is forcibly powered on and the forced warning light is lit.

11. As in request item 1, the cabinet enclosure device, wherein, Below the partition is a transparent folding door, which is secured in its unfolded state by magnets.
