Bonding apparatus for modular shafts
First Claim
1. An athletic apparatus comprising:
- a tubular segment having an inner surface defining a passage;
a shaft segment having a shoulder and a projection extending axially from said shoulder, said projection defining a bonding surface and extending into said passage; and
a bond apparatus between said bond surface and said inner surface, said bond apparatus including an adhesive coupling said tubular segment to said shaft segment and a separation element engaging said inner surface and said bonding surface to maintain at least a predetermined distance between said inner surface and said bonding surface, wherein said separation element is a sphere.

Abstract
The present invention includes an athletic apparatus such as a golf shaft that includes a first tubular segment, a second tubular segment, and a bond apparatus to couple the first and second tubular segments. The first segment includes an inner surface defining a passage. The second segment includes a shoulder and projection extending axially from the shoulder. The projection defines a bonding surface and extends into the passage. The bond apparatus is between the bonding surface and the inner surface of the first segment. The bond apparatus includes an adhesive coupling the first tubular segment to the second tubular segment and a separation element engaging the inner surface of the first segment and the bonding surface of the second segment to maintain at least a predetermined separation distance between the inner surface and bonding surface.
