## Abstract

A golf club grip extension and chipping training aid comprising a tubular grip extension having a central bore sized to accommodate the grip and shaft of a standard golf club such that the golf club can be inserted into the grip extension and secured. The grip extension can be removably attached with a slotted and threaded grommet that fits over the club shaft and screws into threading at the bottom of the grip extension. The club with the grip extension is a chipping training aid that allows a golfer to practice a chip shot with the grip extension pressed against the body to teach the chip shot without movement of the wrists.

## Claims

### Claim 1

A golf chipping training aid that is attachable to a golf club comprising:
a golf club having a tapered shaft with a club head attached to a narrow end of said tapered shaft and a wider grip end with a grip disposed on said grip end; wherein said tapered shaft has a smaller diameter at said narrow end and a larger diameter at said grip end;
an elongated hollow grip extension having an inner bore sized to accommodate the grip at the grip end of the golf club, and an internally threaded end disposed within said inner bore;
a threaded grommet having a tapered central opening and a slot sized to allow the narrow end of said tapered shaft near where the club head is attached to slide into said grommet and allow said grommet to slide toward said wider grip end, wherein said tapered central opening is tapered and sized to engage said tapered shaft, and wherein said threaded grommet is configured to engage and screw into said internally threaded end such that said tapered grommet can be placed around said shaft, said grip inserted into said inner bore, and said threaded grommet screwed into said internally threaded end to securely and removably attach the golf club to said grip extension; and
wherein when said grip extension is held by a golfer against the body said grip extension prevents excess wrist movement when swung by the golfer to teach proper chipping technique.

### Claim 2 (depends on 1)

The golf club training aid of claim 1 wherein the tapered central opening of the threaded grommet allows the grip extension to be attached to golf clubs having different sized shafts thereby allowing the training aid to be removably attachable to multiple clubs.

### Claim 3 (depends on 1)

The golf chipping training aid of claim 1 further comprising;
a cupped plug having a curved inner cup portion, said cupped plug securely inserted into said inner bore to create a stop and to engage the grip of the club to prevent movement of the grip within the inner bore of the grip extension.

### Claim 4 (depends on 3)

The golf chipping training aid of claim 3 wherein the cupped plug allows the grip extension to engage clubs having grips of varying sizes, thereby allowing the training aid to be removably attachable to multiple clubs.

### Claim 5 (depends on 1)

The golf chipping training aid of claim 1 wherein said grip extension is attached to said golf club, and wherein a golfer grips said grip extension near said club and holds said grip extension against the golfer's side and practices a golf stroke wherein said grip extension prevents the golfer's wrist from excessive movement during the swinging motion of a golf chip shot, thereby teaching the proper chipping technique.

### Claim 6 (depends on 1)

The golf chipping training aid of claim 1 wherein said threaded grommet removably attaches the golf club to the grip extension with sufficient strength to allow use of the club in striking a ball during a practice chip.
