Between one leg 2 and the other leg 3, an elevation transmitting means 5 is provided to elevate and lower the other leg 3 with the elevating and lowering of one leg 2.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application J] The present invention relates to an elevating table W1 that is installed in a kitchen, living room, etc. and is movable up and down.

[Prior Art 1] Conventionally, there is a lift table A installed in a kitchen, a living room, etc. as shown in FIG. This is the top plate 1
Lifting legs 2 that can be raised and lowered are provided on the bottom surface, and the lifting legs 2 are extended and contracted up and down by a lifting device provided inside the lifting legs 2, and the top plate 1 is moved up and down to adjust the height. The plan was to do so.

1 Problem to be Solved by the Invention 1 However, in the conventional example as described above, the elevating legs 2 are designed to have a thickness almost equal to the weight and weight of the top plate 1, considering the strength and stability of the elevating table A. If the thickness of the elevating legs 2 is increased in consideration of stability, there is a problem that there is no space to store the legs when the elevating table A is used, making it inconvenient to use.

The present invention is an attempt to solve the above-mentioned problems, and its purpose is to provide a storage space below the top plate for storing the feet when the elevating table is used while ensuring the stability of the elevating table. It provides a convenient lift table.

[Means for Solving the Problems 1] In order to achieve the above object, the elevating table A of the present invention has elevating legs 2 and 3 that can be raised and lowered vertically on both sides of the lower surface of the top plate 1, and one elevating leg 2. A lifting device 4 for raising and lowering the lifting legs 2 is provided inside, one lifting leg 2 and the other lifting leg 3.
When one lifting leg 2 goes up and down, the other lifting leg 3
A lifting transmitting means 5 for lifting and lowering is provided, and storage spaces 6 for storing feet are provided in both lifting legs 2 and 3.

[Function] The lifting legs 2 and 3 arranged on both sides of the lower surface of the top plate 1 provide a storage space 6 for storing the feet under the top plate 1, and both lifting legs 2 and 3 allow the lifting table A to be lifted up and down. Stability can be improved, and a pair of elevating legs 2.
3 is installed, only the lifting device fi4 provided in one lifting leg 2 can connect both lifting legs 2, 3 via the lifting transmission means 5.
The height a of the top plate 1 can be adjusted by raising and lowering.

[Embodiment 1 1] The figure shows an embodiment of the elevating table A of the present invention. This elevating table A consists of a top plate 1 formed in a rectangular shape and a pair of elevating legs 2, 3 that can be raised and lowered on both sides of the lower surface of the top plate 1. 3i
On the first floor, there is a storage space 6 where you can put your feet when using the lift table A. These lifting legs 2 and 3
are fixed legs 2a, 3a and fixed legs 2 installed on the floor.
Fixed legs 2a, 3 in a form that covers the outer surface of g, 3a
Moving piece 2 b, 3 can be moved up and down with respect to a
A lifting device 4 for raising and lowering the lifting leg 2 is installed inside one of the lifting legs 2. An elevating and lowering transmission means 5 is provided between one elevating leg 2 and the other elevating leg 3 for raising and lowering the other elevating leg 3 as one elevating leg 2 goes up and down. A cover material 7 is provided outside the lifting/lowering transmission means 5 between both lifting legs 2.3, so that the lifting/lowering transmission means 5 is not visible from the outside. A drawer 8 is provided between both lifting legs 2 and 3 on the lower surface of the top plate 1, and is designed to store small items used near the lifting table A. Then, one elevating leg 2 is raised and lowered by the elevating device 4, and along with this elevating, the other elevating leg 3 is also raised and lowered together via the elevating and lowering transmission means 5, so that the height position of the top plate 1 is set to p1]! I want to be able to do it. The structure of the lifting device 4 and the lifting/lowering transmission means 5 will be described in detail below.

A lifting device 4 is provided in one of the lifting legs 2, as shown in FIG. This lifting device 4 is installed in the fixed leg 2a of one of the lifting legs 2, and is engaged with a worm transmission mechanism 4b and an ohm transmission mechanism 4b, which are rotated by the drive of the drive motor 4' and the drive motor 4a. The distal end of the rack gear 4c is fixed to the inner surface of the upper end of the movable piece 2b. By driving the drive motor 4a, the ohm gear 4b' of the ohm transmission mechanism 4b rotates, and the rotation of the ohm gear 4b' rotates the ohm wheel 4b''. At this time, the ohm wheel 4b'' rotates. A first gear 9 meshes with the ohm gear 4b' and a second gear 10 meshes with the rack gear 4C.
are integrally provided, and when the worm gear 4b' rotates, the second gear 10 rotates with respect to the rack gear 4C,
By this rotation, the rack gear 4c is moved upward or downward, and the movable piece 2b is moved up and down relative to the fixed leg 2aI. At this time, moveable guide rollers 1] are provided at the four corners of the inner surface of the movable piece 2'b, and the movable piece 2b is connected to the fixed leg 2a.
The fixed leg 2a is configured to roll on the outer surface of the fixed leg 2a as it moves up and down relative to the moving piece 2b, so that it can guide the movable piece 2b without rattling.
A connecting 7 flange 12 connected to the above-mentioned t-mug gear 4b' is provided on opposing surfaces of both moving legs 2b, 3b, and this connecting 7 flange 12 has an elevating transmitting cylinder which is an elevating transmitting hand Fi5. ) 5a connection 7 Runno 5b fixed together 13
It can be attached and detached at will. And one lifting leg 2
is raised and lowered by the drive motor 4a via the ohm transmission mechanism 4b, and the rotation of the ohm wheel 4b'' of the t-me transmission arm 4b rotates the raising and lowering transmission mechanism 5a together with the connection 7 run no. 12. The other elevating leg 3 is also raised and lowered as one elevating leg 2 goes up and down.In other words, the worm transmission mechanism 14b and rack gear 14c are also provided inside the other elevating leg 3. 5& rotates as one of the lifting legs 2 moves up and down,
The ohm transmission mechanism 14b in the other elevating leg 3 is rotated, and the elevating gear 14c is used to move the elevating device up and down.

[Effects of the Invention] Since the elevating table of the present invention is constructed as described above, a storage space for storing feet can be provided below the top plate by the elevating legs arranged on both sides of the lower surface of the top plate. The stability of the lifting table can be improved by both lifting legs, and even if a pair of lifting legs is provided, only the lifting device installed in one lifting leg can move both lifting legs through the lifting transmission means. The height of the top plate can be adjusted by raising and lowering the top plate, improving usability.
