Abstract
Abstract A base is permanently anchored in a foundation in flush relationship therewith. The base includes threaded openings for receiving one or more threaded fasteners. A ball is attached to one end of a tether having an elastic portion and a nonelastic portion. An L-shaped support for the other end of the tether rotates with respect to a frame mounted on the base. The fasteners connect the frame to the base. The frame holds a vertical sleeve. The support has a vertical arm fitting within the sleeve and extending beyond one end thereof and a horizontal arm with a free end extending beyond the perimeter of the frame. A first projection extends radially outward from the vertical arm adjacent to the one end of the sleeve. A second projection extends axially from the one end of the sleeve to abut the first projection when predetermined limits of relative rotation between the sleeve and arm are reached.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
126 words
Tether ball apparatus comprising: a first horizontal rectangular base permanently anchored in a foundation; a frame including a second horizontal rectangular base congruent with the first base, an L-shaped support having a vertical arm rotatably mounted on the frame and a horizontal arm having a free end extending beyond the perimeter of the bases, and a vertical sleeve into which the vertical arm rotatably fits; means for limiting the rotation of the vertical arm within the sleeve; means for fastening the second base to the first base; a ball; and a tether having one end attached to the ball and the other end attached to the free end of the horizontal arm, the tether being long enough to permit the ball to lie on the foundation.
Claim 2
Dependent Claim
126 words
Tether ball apparatus comprising: a first horizontal rectangular base permanently anchored in a foundation; a frame including a second horizontal rectangular base congruent with the first base, an L-shaped support having a vertical arm rotatably mounted on the frame and a horizontal arm having a free end extending beyond the perimeter of the bases, and a vertical sleeve into which the vertical arm rotatably fits; means for limiting the rotation of the vertical arm within the sleeve; means for fastening the second base to the first base; a ball; and a tether having one end attached to the ball and the other end attached to the free end of the horizontal arm, the tether being long enough to permit the ball to lie on the foundation.
Claim 3
Dependent Claim
72 words
The apparatus of claim 1, in which the vertical arm extends beyond one end of the sleeve and the limiting means comprises a first projection extending radially outward from the vertical arm adjacent to the one end of the sleeve and a second projection extending axially from the one end of the sleeve to abut the first projection when predetermined limits of rotation of the vertical arm within the sleeve are reached.
Claim 4
Dependent Claim
44 words
The apparatus of claim 2, in which the one end of the sleeve is the top end and the first projection rests on the surface of the top end of the sleeve to limit the axial movement of the vertical arm in the sleeve.
Claim 5
Dependent Claim
17 words
The apparatus of claim 3, in which the tether has an elastic portion and a nonelastic portion.
Claim 6
Dependent Claim
15 words
The apparatus of claim 1, in which the first base is flush with the foundation.
Claim 7
Dependent Claim
32 words
The apparatus of claim 1, in which the first base comprises a plurality of aligned holes in the bases, a threaded fastener through each opening, and a nut threaded on each fastener.
Claim 8
Dependent Claim
30 words
The apparatus of claim 1, in which the frame further includes four upwardly and inwardly extending beams connected between the respective corners of the second base and the vertical sleeve.
