Abstract
Abstract A basketball goal unit for use with a basketball backboard including a rigid backboard mounting frame adapted to be securely mounted to said backboard and a goal mounting frame configured for cooperative interengagement with the backboard mounting frame. A goal is carried by the goal mounting frame and a pivot shaft interconnects the goal mounting frame with the backboard mounting frame to permit pivotal rocking movement of the goal and goal mounting frame about a transverse pivot axis in response to the goal being struck or slapped or hung from, as by a player during a "dunk" shot. A curved leaf spring provides resilient coupling between the goal mounting and backboard mounting frames to permit resilient movement of the goal about the pivot axis, and a double-acting shock absorber provides damped coupling between said goal mounting and backboard mounting frames during this pivotal rocking movement.

Claim 1
Independent Claim
375 words
A basketball goal unit for use with a basketball backboard having a front surface and comprising a rigid backboard mounting frame adapted to be securely mounted on the front surface of said backboard, including a first portion configured for lying against said backboard and for being secured thereto, and a second portion extending outwardly from said first portion, and, thereby, outwardly from the front surface of said backboard, a goal mounting frame configured for cooperative interengagement with said backboard mounting frame, said goal mounting frame being configured for overlying the second portion of said backboard mounting frame, a goal carried by said goal mounting frame, a pivot shaft for pivotally interconnecting said goal mounting frame with said backboard mounting frame to permit pivotal rocking movement of said goal and goal mounting frame about a transverse pivot axis, said pivot shaft connecting said goal mounting frame to said second portion of said backboard mounting frame, said goal mounting frame having a pivot shaft-remote portion extending from said pivot shaft toward said backboard, first coupling means for providing resilient coupling between said goal mounting and backboard mounting frames to permit resilient pivotal rocking movement of said goal about said pivot axis, and second coupling means for providing shock absorbing coupling between said goal mounting and backboard mounting frames during said pivotal rocking movement of said goal about said pivot axis, said first coupling means interconnecting said second portion of said backboard mounting frame and said pivot shaft-remote portion of said goal mounting frame, said second coupling means interconnecting said first portion of said backboard mounting frame and said pivot shaft-remote portion of said goal mounting frame, said pivot shaft-remote portion of said goal mounting frame and said second portion of said backboard mounting frame each being of channel section and of inverted-U configuration and each thereby having side flanges, said pivot shaft extending through said side flanges, said goal mounting frame thereby being pivotally secured to permit rocking movement of said goal about said pivot axis relative to said backboard upon said goal being displaced downwardly by external application of force, said first coupling means comprising a spring interengaging said second portion of said backboard mounting frame and said pivot shaft-remote portion of said goal mounting frame.
Claim 2
Dependent Claim
375 words
A basketball goal unit for use with a basketball backboard having a front surface and comprising a rigid backboard mounting frame adapted to be securely mounted on the front surface of said backboard, including a first portion configured for lying against said backboard and for being secured thereto, and a second portion extending outwardly from said first portion, and, thereby, outwardly from the front surface of said backboard, a goal mounting frame configured for cooperative interengagement with said backboard mounting frame, said goal mounting frame being configured for overlying the second portion of said backboard mounting frame, a goal carried by said goal mounting frame, a pivot shaft for pivotally interconnecting said goal mounting frame with said backboard mounting frame to permit pivotal rocking movement of said goal and goal mounting frame about a transverse pivot axis, said pivot shaft connecting said goal mounting frame to said second portion of said backboard mounting frame, said goal mounting frame having a pivot shaft-remote portion extending from said pivot shaft toward said backboard, first coupling means for providing resilient coupling between said goal mounting and backboard mounting frames to permit resilient pivotal rocking movement of said goal about said pivot axis, and second coupling means for providing shock absorbing coupling between said goal mounting and backboard mounting frames during said pivotal rocking movement of said goal about said pivot axis, said first coupling means interconnecting said second portion of said backboard mounting frame and said pivot shaft-remote portion of said goal mounting frame, said second coupling means interconnecting said first portion of said backboard mounting frame and said pivot shaft-remote portion of said goal mounting frame, said pivot shaft-remote portion of said goal mounting frame and said second portion of said backboard mounting frame each being of channel section and of inverted-U configuration and each thereby having side flanges, said pivot shaft extending through said side flanges, said goal mounting frame thereby being pivotally secured to permit rocking movement of said goal about said pivot axis relative to said backboard upon said goal being displaced downwardly by external application of force, said first coupling means comprising a spring interengaging said second portion of said backboard mounting frame and said pivot shaft-remote portion of said goal mounting frame.
Claim 3
Dependent Claim
66 words
A basketball goal unit according to claim 1 and further characterized by said spring comprising an elongated length of strip material having a central portion, and opposite end portions extending laterally outwardly from said central portion, said central portion engaging the second portion of said backboard mounting frame, said opposite end portions of said spring being interconnected with the shaft-remote portion of said goal mounting frame.
Claim 4
Dependent Claim
60 words
A basketball goal unit according to claim 2 and further characterized by said spring resiliently biasing said pivot shaft-remote portion of said goal mounting frame toward the said second portion of said backboard mounting frame, and means adjustably connecting said opposite ends of said spring to said shaft-remote portion of said goal mounting frame, whereby said spring may be pretensioned.
Claim 5
Dependent Claim
65 words
A basketball goal unit according to claim 3 and further characterized by said spring being in the form of an elongated strip of tempered steel and said center portion being an upwardly curved bight providing said spring with the configuration of an inverted-U of shallow character, said bight being located for bearing against the under surface of said second portion of said backboard mounting frame.
Claim 6
Dependent Claim
80 words
A basketball goal unit according to claim 1 and further characterized by said second coupling means comprising a double acting shock absorber having opposite ends movable toward or away from each other by contraction or elongation of said shock absorber, said shock absorber providing damping for both contraction and elongation, said first portion of said backboard mounting frame and said shaft-remote portion of said goal mounting frame each including means for securement of a respective end for said shock absorber.
Claim 7
Dependent Claim
27 words
A basketball goal unit according to claim 5 and further characterized by a cover enclosing portions of said backboard mounting frame and for enclosing said shock absorber.
Claim 8
Dependent Claim
29 words
A basketball goal unit according to claim 1, said first and second coupling means being located within corresponding side flanges of said goal mounting and said backboard mounting frames.
Claim 9
Dependent Claim
30 words
A basketball goal unit according to claim 1 and further characterized by a cover enclosing portions of said backboard mounting frame for concealment of said first and second coupling means.
