Embodiment Construction

[0077] See first figure 1 , A self-stabilizing base 1 that can be stacked horizontally is shown, and an object is supported by a hub 2 (not shown). The base 1 has four legs 3, 4, 5, 6 extending from the hub 2, and the third leg 5 and the fourth leg 6 are rigidly fixed to the hub 2 or formed as a part of the hub 2. The first leg 3 and the second leg 4 are fixed to each other by a beam 7, which is pivotally connected to the hub by bolts, rivets, or similar axially fixed shafts or pins 8, so that the legs 3 and 4 can pivot together The shaft turns. This mechanism is similar to that disclosed in U.S. Patent Nos. 3,814,362, 3,844,517, and 5,690,303, the details of each of which are incorporated herein by reference, and generally have reflection symmetry.

[0078] In order to prevent spinupsidedown or preferably further restrict the rotation of the pivoting leg part 10 (including the first leg 3, the second leg 4 and the beam 7) so as to limit the degree of engagement of the mechanism...

Abstract

A stabilising arrangement (base 1) to support an object above four legs (3-6) extending from a hub (2) connected by a stem to the object to be supported. At least one of the legs is pivoted at the hub such that at least two feet (13-16) are adjustable relative to the hub to enable the stabilising arrangement to conform to a warped support surface. Leg geometry of the stabilising arrangement is such that, when a first and a second said stabilising arrangement are horizontally (laterally) stacked with respect to one another, two of the legs of the first or second stabilising arrangements include a region that passes partially under the hub and / or under a region of a leg of the other stabilising arrangement. The first and second legs (3, 4) can be lower than the third and fourth legs (5, 6). Also the first and second legs (3, 4) can be closer (e.g. on legs that are shorter or at 80 degrees) to each other and the third and fourth legs (5, 6) can be wider apart e.g. on legs that are longer or at 100 degrees, to provide a narrower spacing of the feet 13 and 14 that can fit between the feet 15 and 16.

Description

Technical field [0001] The present invention relates to self-stabilizing support brackets and bases and in particular to four-legged nested support brackets or bases for supporting objects such as signs, speakers, foldable desktops and medical equipment. Background technique [0002] There are known many different forms of pedestal bases for supporting various objects such as temporary signs, surround sound speakers, medical equipment and foldable desktops (foldable between the working position and the storage position when in use). Some of these pedestal bases have four legs that can fit on uneven ground in order to provide improved stability of the occupied space (a quadrilateral formed by connecting four ground joints or feet) consistent with, for example, a square table top. [0003] However, when the two self-stabilizing bases are tightly stored together, the legs of one base cannot overlap the legs of the base or pass through from below or over the legs of the base, which lim...
