Abstract

A golf club positioning and position indicating device having a mounting base that is releasably attached to the shaft of a golf club below the handgrip of the club. A positioning head support for support and orientation of a positioning head which can be visually inspected by a golfer when addressing the golf ball in preparation for the intended golf stroke. The positioning head support is releasably received in specifically oriented relation by the mounting base to provide for simple and efficient assembly or disassembly of the positioning head relative to the mounting base. A spirit level support is connected in adjustable pivotal relation with the positioning head support and retains a circular spirit level of a dimension that can be easily visually inspected by a golfer holding the golf club at the ball addressing position. The spirit level has a crystal having orientation indicia thereon which enables a golfer to ascertain selective alignment of the bottom edge of the golf club head to enable accurate striking of the golf ball. The indicia further provides reference lines for orienting the positioning device with respect to the shaft of the golf club. The indicia permits selective orienting of the club head and face to "up", "down", "open" or "closed" positions to impart a controlled trajectory to the ball.

Dependent claims

A positioning and position indicating device for releasable attachment to the shaft of a golf club having a head defining a reference edge, comprising:

(a) a mounting base adapted to be supported on a shaft of a golf club and having a mounting block defining a non-circular orienting receptacle therein and having a clamping block adapted for receiving the shaft of the golf club and retaining said mounting block in substantially immovable relation with the shaft of the golf club;
(b) a positioning head support being disposed in releasable and oriented assembly with said mounting base and having non-circular mounting means being received in oriented assembly by said non-circular orienting receptacle;
(c) a positioning head being connected to said positioning head support and being selectively positionable relative thereto:
(d) means retaining said non-circular mounting means in releasable, substantially immovable assembly within said non-circular orienting receptacle and supporting said positioning head support in substantially immovable relation with said mounting base;
(e) a generally circular spirit level being provided on said positioning head and being located for inspection by a golfer holding the golf club in position for addressing a golf ball lying on the ground for determination of the position at which the golf club is being held, said spirit level having a closed chamber with fluid therein and an a gas bubble present within said fluid;
and
(f) indicia means being present on said spirit level for orientation relative to said gas bubble at various positions of the golf club shaft, said indicia means having reference marks identifying up, down, open and closed positions of the reference edge of the head of the golf club when said golf club is positioned to address a golf ball.

A positioning and position indicating device for releasable attachment to the shaft of a golf club having a golf club head defining a reference edge, comprising:

(a) a mounting block defining a recess for receiving a golf club shaft and having a non-circular orienting passage therein for orientation in substantially parallel relation with the golf club shaft;
(b) a clamping block defining a recess for receiving a golf club shaft;
(c) mounting elements for securing said mounting block and said clamping block in substantially immovable and releasable relation with a golf club shaft;
(d) a positioning head support having a non-circular orienting element extending in fixed relation therefrom and received within said non-circular orienting passage;
(e) means securing said non-circular orienting element in immovable and releasable assembly within said non-circular orienting passage;
(f) a positioning head being in positionable assembly with said positioning head support;
(g) a spirit level being supported by said positioning head in position for visual inspection by a golfer holding the golf club in position for striking a golf ball and having a liquid therein and a position indicating gas bubble within said liquid;
and
(h) reference indicia on said spirit level for reference with said gas bubble for indicating selected positions of the golf club in relation to the reference edge of the golf club head when the golf club is being held in position for striking a golf ball.
