Description

TECHNICAL FIELD The present invention relates to a tabletop elevating fixture.

2. Description of the Related Art Generally, desks are installed in work spaces such as offices and public facilities to provide users with work areas. The height of the worktop that is easy to work with differs from person to person depending on the user's posture, physique, gender, preference, and so on. For this reason, fixtures that allow the height of the top to be raised and lowered are used.

As techniques for raising and lowering the top plate, for example, a method using a gas spring, a method using a gear, and the like are known (see Patent Documents 1 and 2 below).

The fixtures with a liftable top plate described in Patent Literatures 1 and 2 have a simple structure, so that the cost can be kept low. However, it may be difficult for users with weak strength to operate it, and depending on the height of the tabletop, the user may be forced to take an unreasonable posture in order to raise and lower the tabletop.

Therefore, in order to improve operability when raising and lowering the tabletop, a technique for raising and lowering the tabletop using an electric drive unit is widely known (see Patent Document 3 below).

Therefore, by changing only the end base legs 60, it is possible to deal with top plates 11 of various sizes, shapes, and the like.

Further, since the extension direction of the end base legs 60 can be changed with respect to the extension direction of the intermediate base legs 80, the extension of the end base legs 60 can be changed according to the size, shape, etc. of the top plate 11. You can react by changing direction.

Also, the upper protruding portion 84 of the intermediate base leg 80 is arranged in the lower through-hole portion 61c of the end base leg 60, and the connection position between the intermediate base leg 80 and the end base leg 60 is positioned. By selectively engaging the engagement projection 86 of the intermediate base leg 80 with one of the plurality of engagement recesses 64 of the end base leg 60 , the extension direction of the end base leg 60 can be adjusted. can be adjusted.

The end base leg 60 is vertically sandwiched between the intermediate base leg 80 and the lifting leg 3 and the joint member 50, and the intermediate base leg 80 and the joint member 50 are screwed together. Therefore, the elevating leg 3, the intermediate base leg 80 and the end base leg 60 can be connected by screwing once.

In addition, the outer adjuster 70 is arranged laterally outward of the inner adjuster 90 . Therefore, when a load (see arrow X in FIG. 1) acts from the outer side to the inner side of the table top 11, the supporting strength of the legs 2 supporting the table top 11 can be increased. Shaking of the device 100, vibration, generation of abnormal noise, etc. can be further suppressed.

Further, the inner adjuster 90 and the outer adjuster 70 are arranged so as to overlap the top plate 11 in plan view. Therefore, when a plurality of table devices 100 are arranged adjacent to each other, the legs 2 do not interfere with each other when the top plates 11 are arranged adjacent to each other.

In addition, a plurality of ribs 63 protruding radially inward are provided on the inner peripheral surface of the end base leg 60 . Therefore, even if a downward force acts on the end base leg 60 and the end base leg 60 tilts, the rib 63 abuts the upper bulging portion 84 of the intermediate base leg 80, thereby suppressing further tilting. be done.
