Abstract
Abstract Disclosed is a collapsible support base for supporting one end of an elongated shaft. The support includes four legs arranged in opposing pairs so as to form two cross members. The central portion of one cross member is flexible so as to be compressible to a smaller cross-sectional dimension, facilitating its insertion in a central portion of the other cross member. When interfitted, the two cross members are interlocked so that a preselected angular displacement between the legs thereof is maintained. In one embodiment, the cross members are pivotally interconnected one with the other at a central shaft-receiving portion. The central portions of the cross members may also include detent means for locking the cross members at a preselected angular position. The cross members may also be telescopically insertable one with the other with no provision for relative pivotal displacement.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
278 words
A collapsible support base for receiving an end of an elongated shaft so as to support portions of the shaft extending beyond the base, said collapsible support base comprising: a pair of cross members made of plastic and being interfitted with each other to swing between a collapsed position and an open position, each cross member including a pair of upper and a pair of lower opposed leg portions, the lower legs having outer ends for engaging the floor and for supporting the base and elongated shaft, inner ends on the upper and lower leg portions, the opposed leg portions being spaced from each other, detent means on the collapsible support base to detent the cross members in an open position to support the shaft, upper and lower cross bars spanning the inner ends of the opposed leg portions, hub portions at the center of the cross bars on each of the cross members for mating rotational engagement and having openings therein to receive the elongated shaft, upright frame members extending between the upper and lower leg portions to make the cross members more rigid for supporting a load thereon, the cross bars defining upper and lower sides of a central opening and the upright frame members defining opposite sides of a central opening, said cross bars spanning the opening, said cross bars being deflectable with the cross members adapted to be interfitted upon insertion of a leg portion of one cross bar between the upright frame members of the other cross member and deflecting the cross bars to engage the hub portion on the inserted cross bar inside of the hub portion on the outer cross member.
Claim 2
Dependent Claim

A collapsible support base for receiving an end of an elongated shaft so as to support portions of the shaft extending beyond the base, said collapsible support base comprising: a pair of cross members made of plastic and being interfitted with each other to swing between a collapsed position and an open position, each cross member including a pair of upper and a pair of lower opposed leg portions, the lower legs having outer ends for engaging the floor and for supporting the base and elongated shaft, inner ends on the upper and lower leg portions, the opposed leg portions being spaced from each other, detent means on the collapsible support base to detent the cross members in an open position to support the shaft, upper and lower cross bars spanning the inner ends of the opposed leg portions, hub portions at the center of the cross bars on each of the cross members for mating rotational engagement and having openings therein to receive the elongated shaft, upright frame members extending between the upper and lower leg portions to make the cross members more rigid for supporting a load thereon, the cross bars defining upper and lower sides of a central opening and the upright frame members defining opposite sides of a central opening, said cross bars spanning the opening, said cross bars being deflectable with the cross members adapted to be interfitted upon insertion of a leg portion of one cross bar between the upright frame members of the other cross member and deflecting the cross bars to engage the hub portion on the inserted cross bar inside of the hub portion on the outer cross member.
Claim 3
Dependent Claim
55 words
A collapsible support in accordance with claim 1 in which the upper and lower cross bars have portions laterally offset from each other and in parallel planes, the cross bars of one cross member being rotatable to contiguously adjacent the cross bar of the other cross member when the base is in the collapsed position.
Claim 4
Dependent Claim
65 words
A collapsible support base in accordance with claim 1 in which a hub portion on a first cross member comprises a cylindrical sidewall projecting from its cross bar, a hub portion on the other cross bar having a substantially cylindrical socket, said cylindrical sidewall being journaled in the cylindrical socket to rotatably mount the first and second cross members to each other for swinging movement.
