Launch and catch apparatus, kits including the same, and methods of using the same to launch and catch balls and other projectiles. The apparatus include a frame and a tubular body operatively coupled to the frame. The frame includes a handle and defines an inlet opening sized to receive a projectile. The tubular body includes an inlet region operatively coupled to the frame to receive the projectile when the projectile passes through the inlet opening. The tubular body further includes an outlet region configured to receive and retain the projectile after the projectile passes through the inlet opening. The apparatus is configured to launch the projectile out of an outlet opening of the outlet region. The outlet opening may have an adjustable nominal size and may be configured to resiliently expand when a projectile is launched out of the outlet opening.

Embodiments of golf coupling mechanisms for joining golf club heads and shafts are described herein. The golf coupling mechanism allows for adjustment of a club head loft angle, a club head lie angle, and a golf club shaft length while utilizing one club head and one shaft. In a fully extended configuration, the golf coupling mechanism includes a shaft sleeve, a removable spacer, and a removable extender, wherein a fastening assembly secures the golf coupling mechanism to the golf club head. In a contracted configuration, the golf coupling mechanism includes the shaft sleeve. The golf coupling mechanism further includes a shaft cap to soften the interaction between the shaft and the golf coupling mechanism. The golf coupling mechanism further comprises one or more arcuate coupler sets to frictionally lock the shaft relative to the golf club head.

A swing motion trainer used to simulate one or more sport swing movements includes a rod portion comprising a shaft with a grip. The swing motion trainer includes a resistance portion comprising an interchangeable mechanism at a distal end of the rod portion, the resistance portion includes an interchangeable mechanism at the distal end of the rod portion, wherein the interchangeable mechanism is configured to attach a removable resistance element to the distal end of the rod portion. The removable resistance element that is attachable to the distal end of the rod portion via the interchangeable mechanism. The removable resistance element provides a resistance to a swinging motion of the swing motion trainer.

A golf club has a first shaft coupled to a club head, a second shaft configured to slidably engage a portion of the first shaft, a grip coupled to the second shaft, and an adjustable length shaft assembly received by the second shaft and configured to allow a portion of the first shaft to slide in relation to the second shaft in a first configuration, and to restrict a portion of the first shaft from sliding in relation to the second shaft in a second configuration. The grip is restricted from rotation about the first shaft or the second shaft as the first shaft slides in relation to the second shaft.

A golf club shaft connection assembly comprising first and second shaft sections, male and female adaptors, a hollow retainer, a spring, and a plurality of balls is disclosed herein. The male and female adaptors are each attached to the first and second shaft sections, respectively, preferably with a permanent adhesive. The male adaptor comprises a protrusion that fits within a keyed interior of the female adaptor, and moving the hollow retainer towards the male adaptor reversibly fixes the two adaptors together, while moving the hollow retainer towards the female adaptor allows the male adaptor to be removed from the female adaptor.

A key includes an out of round cross section which rotates to expand a compression unit in a golf club shaft. The top of the key has an extension which moves in a slot within the compression unit to define the maximum active and inactive positions.

A screw based compression unit within a golf grip that fits within a golf club shaft to support a core and rubber grip.

A length adjustable golf club includes a club head attached to a shaft at a lower end. A length adjusting kit includes a shaft insert that attaches to the shaft at an upper end. The shaft insert includes a coupling port that accepts one of an extension block or a grip adapter. To provide length adjustments of the overall club length, one or more extension blocks may attached between the shaft insert and the grip adapter. A grip assembly having a reinforcing sleeve connects to the grip adapter and extends over the shaft and any extension blocks. The grip assembly couples to the shaft through a grip adapter and grip coupling. The grip adapter and grip coupling are axially moveable prior to securement with a retaining fastener. The grip coupling may be rotationally constrained or rotationally adjustable relative to the grip adapter.
