Abstract

Abstract A golf putting apparatus consists of a deck having an upper putting surface which deck is variably adjusted with respect to a base by means of several height adjustment devices, each comprising a bolt turnable by a handle and having a nut threaded thereon, which nut is held captive with respect to the deck so that turning of a respective handle effects a variance of the height of a portion of the deck and of the magnitude of the slope of the deck surface.

Claims Analysis

Total Claims: 2
Claim 1
Independent Claim 182 words
Putting practice apparatus comprising: a frame, a planar deck supported by the frame and having an apertured upper surface defining a putting surface, a plurality of spaced vertically-extending turnable threaded bolts for varying the height of at least a part of the deck and the magnitude of the slope of the deck upper surface, the deck having a degree of deformability for allowing its contour to be varied by the changing of the height of at least one region thereof, a plurality of spaced C-shaped locator brackets fixed to the frame and supporting a respective one of the bolts extendable therethrough, at least one of the locator brackets being adjustable in height, a cranklike handle attached to each bolt for permitting bolt rotation in the height adjustment function, the deck being provided with a plurality of cutaway portions along the side edges thereof, a captive nut being nestably receivable within each cutaway portion and threaded on the respective bolt extendable therethrough, an encapsulating housing enclosing a respective cutaway portion and holding a respective captive nut in situ within the respective cutaway portion.
