    摘要: In legged furniture having four or more legs and a load-receiving stage supported directly or indirectly by these legs, this legged furniture includes three main legs defining a triangular shape in a plurality of the legs and, assuming that the legged furniture is placed by using only the main legs, enabling a stable stationary attitude of the load-receiving stage, and a leg adjuster forming an extension portion of a sub leg other than the main legs and capable of expansion/contraction in a vertical direction and providing an expansion/contraction leg in cooperation with the sub leg and autonomously allows expansion or contraction of the expansion/contraction leg on the basis of a length of the main leg in accordance with the stationary attitude of the load-receiving stage.

    摘要: A self stabilizing system which has an incompressible coil at least partially encompassed in a housing, and which controls a foot of a device to be stabilized. The coil abuts a plunger, which plunger is for allowing a user to selectably lock the elevation by use of a pin which fits within a plurality of annular grooves on the plunger. In a first embodiment, a pair of coils surround the plunger on either side and control a pair of feet, thus allowing automatic stabilization on an uneven surface. In a second embodiment, a single coil is controlled by a spring which abuts the plunger allowing a spring-loaded system for selecting an elevation to lock the plunger.

    摘要: A stabilizing arrangement (1) to support an object above four ground engaging means (2c,3c,4c,5c) has first 2, second 3, third 4 and fourth 5 levers each having a beam portion (2a,3a,4a,5a), an actuating portion (2b,3b,4b,5b) and a ground engaging means (2c,3c,4c,5c). Each lever is connected to a common interconnection means (6) by a respective pivot with a pivot axis. The levers engage consecutively first to second, second to third, third to fourth and fourth to first, via respective projections (2d,3d,4d,5d) permitting ground engaging means warp displacement and thereby the arrangement provides support of the object on uneven ground. For each lever part, the distance a between the respective ground engaging means and the respective pivot axis is a primary lever-rotating moment arm, and the distance b between the respective ground engaging means and the centre of the pivot is a friction loading distance. The friction loading distance b can be greater than or equal to the primary lever-rotating moment arm a.
