Are mounted on a frame 3 so as to be rotatable in a vertical direction with a support shaft 6, and the rotation center thereof is supported. Specifically, the support shaft 6 at the center of rotation of the arm 2 corresponding to the planetary gears 4a, 4b, ... or the sprockets 5a, 5b, ... provided on the top plates 1a, 1b, ... A sun gear 7 or a sprocket 8 that rotates is provided on the same body.

[0010] Each top plate 1 supported by the arm 2
a and 1b, and a sun gear 7 or a sprocket 8 provided at the center of rotation of the arm 2 and each of the top plates 1a, 1b,.
The planetary gears 4a, 4b,... Or the sprockets 5a, 5b,.
b,... or connected via a chain 10 to form a planetary rotation mechanism.

Each of the top plates 1a, 1 which rotates around the sun gear 7 or the sprocket 8 of the arm 2 in a planetary manner.
In order to fix and hold b,... at any desired position (height), it is preferable to provide a braking mechanism B for controlling the rotation of the arm 2.

Various mechanisms and configurations are conceivable as this type of braking mechanism.
The worm gear 11 is mounted coaxially with the sun gear 7 or the sprocket 8, and a worm 13 provided with a handle 12 for rotating the worm gear 11 is provided on the underframe 3 side. According to this embodiment, by rotating the handle 12, the arm 2 is rotated in the vertical direction via the worm 13 and the worm gear 11, and the top plates 1a, 1b,. When the rotation operation of the handle 12 is stopped, the top plates 1a, 1
are fixedly held at desired positions (heights).

In addition to the above, a known brake mechanism combined with a brake drum and a brake shoe and controlled by a brake operating lever is used, or the arm 2 is rotated by a drive device such as a motor having a brake mechanism. Although conceivable, the invention is not limited to these braking mechanisms.

When the arm 2 is rotated clockwise or counterclockwise in the vertical direction, for example, by rotating the handle 12, the sun gear 7 or the sprocket 8 provided at the center of rotation of the arm 2 is rotated. Each top plate 1 as the center
a, 1b,... rotate in a planetary manner while maintaining a horizontal state. Therefore, if the arm 2 is in a horizontal state as shown in FIG.
a, 1b,... are arranged in the same plane to form a wide table, and if the arm 2 is inclined as shown in (b), the height of each top plate 1a, 1b,. When the arm 2 is set in a vertical state as shown in FIG. 3C, the top plates 1a, 1b,... Are arranged up and down to form a storage rack.

At this time, if the loads on the top plates 1a, 1b,... Are balanced, the state can be maintained without providing a special braking mechanism, and the top plate 1a, 1b,. Each top plate 1a, 1b,
Can be moved to a desired position (height).

[0016]

The multipurpose table according to the present invention has a plurality of top plates rotatably supported on an arm, a planetary gear or a sprocket is provided at the center of rotation of each top plate, and the arm is mounted on a frame. It is mounted at the center of rotation of the arm, because it is mounted vertically rotatable, and the sun gear or sprocket provided at the center of rotation of the arm and the planetary gear or sprocket provided at each top plate are connected by a gear train or chain. Each top plate rotates around the planet around the sun gear or sprocket while maintaining the horizontal state, and multiple top plates are arranged in the same plane to form a wide table, or multiple top plates The height of the tabletop is shifted like a staircase to form a display stand, or a plurality of top plates are arranged vertically to form a storage base. In this way, by changing the height and arrangement of each top plate according to the purpose of use, the table can be used for various purposes as a work table, a storage stand, a display stand, or the like.

In addition, when used as a work table, when changing the assembly in a certain kind of assembling work, the top plate is rotated by planetary rotation to change the height and arrangement as appropriate, thereby allowing the article to be held and moved. It is possible to easily change the setup without changing or reloading, and it can be used for transferring the articles placed on the top plate regardless of the assembling work.

Furthermore, when used as a storage rack or a display stand, various items can be easily loaded on the upper and lower tiers by rotating each of the top plates and changing the height and arrangement as appropriate.・ Can be stored.
