Abstract

Abstract A swing for both arcuate and rotational motion has a disc platform for passengers and multiple, congruently attached support strands adapted for securing to a horizontal support member. The bight of a strand passes around the support member such that two free ends of the strand may pass through the disc to locks to adjustably secure the ends to the disc. The strand pairs are fixed to the horizontal support member at spaced positions on the member congruent with the position of the strands on the disc. The disc is provided with a peripheral rim having top and bottom walls. Extending through the walls are a plurality of spaced apart vertical apertures. The lower wall is provided with a depression placed adjacent each aperture. Extending across the depression and spaced from the bottom of the depression is a rigidly attached lock bar. The disc platform is swingedly attached to the support by passing each end of each strand pair through a vertical aperture and each end is then passed between the bottom of the depression and the lock bar and anchored at that point.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 160 words
A swing to be supported from a horizontal support member for both arcuate and rotational motion and comprising a rider support disc, a peripheral rim on the disc, said rim having top and bottom walls, a plurality of substantially vertical apertures extending through said walls of said rim of said disc, a plurality of support strands, means for fixing the strands at spaced positions about the horizontal support member, a semi-spherical depression in said bottom wall of the disc adjacent each vertical aperture in said wall, a lock bar across the hollow defined by the semi-spherical depression, and a radially intruding boss on the disc containing said bar and said hollow, each semi-spherical depression and lock bar cooperating to adjustably secure each opposite end of a strand passing through a vertical aperture to said disc, the ends of said strands being congruently arranged with respect to the disc as the strands are arranged with respect to the horizontal support member.
Claim 2
Dependent Claim 160 words
A swing to be supported from a horizontal support member for both arcuate and rotational motion and comprising a rider support disc, a peripheral rim on the disc, said rim having top and bottom walls, a plurality of substantially vertical apertures extending through said walls of said rim of said disc, a plurality of support strands, means for fixing the strands at spaced positions about the horizontal support member, a semi-spherical depression in said bottom wall of the disc adjacent each vertical aperture in said wall, a lock bar across the hollow defined by the semi-spherical depression, and a radially intruding boss on the disc containing said bar and said hollow, each semi-spherical depression and lock bar cooperating to adjustably secure each opposite end of a strand passing through a vertical aperture to said disc, the ends of said strands being congruently arranged with respect to the disc as the strands are arranged with respect to the horizontal support member.
Claim 3
Dependent Claim 29 words
A swing in accordance with claim 1 wherein the means fixing the strands to the horizontal support member comprises several loops of each strand around said horizontal support member.
Claim 4
Dependent Claim 56 words
A swing in accordance with claim 1 wherein the means for fixing the strands to the horizontal support member comprises a plate, having a plurality of spaced apart apertures therein, said plate being secured to said support by at least one attachment member, said apertures defining means for separating the strands with respect to the plate.
Claim 5
Dependent Claim 81 words
A swing in accordance with claim 1 wherein the means for fixing the strands to the horizontal support member comprises a plurality of like wedge segments each having an arcuate inner wall, a compound curving outer wall, and radial side walls, an aperture in said side walls and being aligned when the segments are joined in a side by side relationship, and a flexible securing line passing through said apertures sequentially to secure the wedge segments together about said support member.
