A toy ball which emits sounds as it is rolled and including a ball body and a plurality of mechanically-operated sound producing tubes carried within the ball body, each sound producing tube including a sound-producing device which moves by the force of gravity, and each sound producing tube lying along a longitudinal axis, in which the axes are transverse to one another so that the sound producing devices emit sound when the ball is rolled along various axes. The ends of the sound-producing tubes are held by sleeves that are molded as integral parts of the ball body.

A golf club head comprises a sole, a recessed sole port in the sole; and a rotatably adjustable sole piece adapted to be at least partially received within the sole port and comprising a central body having a plurality of contact surfaces adapted to contact the sole port and being offset from each other along a central axis extending through the central body of the sole piece. The sole piece can be positioned at least partially within the sole port at five or more rotational and axial positions with respect to the central axis, wherein at each rotational position, at least one of said contact surfaces of the central body contacts the sole port to set the axial position of the sole piece. The sole port and/or the sole piece can be generally pentagonal in shape.

A flag tag system for removable mating with a resilient cylindrical cup-shaped member defining a socket includes a flag retention frame connected to the flag, a post connected to the flag retention frame, and a plurality of discs or arms connected to the post, the plurality of discs or arms for mating with the socket. The flag tag system is for a flag football or similar tag game using a flag that is pulled by force to tag a player. A first device with the shaped member defining the socket is worn on a belt by the player. The plurality of discs or arms mates by pressing into the socket of the shaped member. The flag retention frame carries a flag. The plurality of discs or arms can provide select pull or force tension for grabbing the flag and thereby popping the discs or arms from engagement with the socket of the shaped member. Embodiments also include a buckle system of a plug with arms for snug connection to a socket.

A golf club head includes a body having a recessed channel formed in an outer surface. A weight assembly that includes a weight at least partially disposed within the recessed channel, a cover extending at least partially over the recessed channel, and a fastener coupling the cover to the body. The fastener is adapted to retain the weight in the recessed channel only indirectly by the cover. The weight is slidably engaged with the cover and the cover is positionable in at least an unlocked configuration whereby the cover is raised at least partially out of the recessed channel and the weight is selectively slidable within the recessed channel, and a locked configuration whereby the cover is at least partially disposed within the recessed channel and the weight is secured within the recessed channel. The weight moves with the cover between the unlocked configuration and the locked configuration.

A low friction rehabilitation board having an integral band retaining feature is described. The rehabilitation board may have a coefficient of static friction of no more than about 0.5 and in some embodiments no more than about 0.06. The rehabilitation board has a plurality of band retaining feature configured along one or both ends and may be an integral band retaining features being formed in the board. Additionally, the rehabilitation may include one or more band retaining features on one or both sides of the board. The unique configuration of the band retaining features enables rehabilitation method heretofore not possible with a single board. Resistance bands may be retained in the band retaining features and coupled to a user's limb, such as a foot or ankle, to resist motion, such as sliding or extending the foot along the low friction surface of the rehabilitation board.

An inflatable plyometric box having a first inflatable member adapted to be inflated to a pressure, a second inflatable member on top of the first inflatable member and adapted to be inflated to a pressure, and a connecting member connected to the first inflatable member and the second inflatable member which secures the first inflatable member to the second inflatable member. The first and second inflatable members incorporate drop stitch technology which provides substantial rigidity to first and second inflatable members when the first and second inflatable members are inflated to the pressures. Thus the inflatable plyometric box is substantially rigid to support a user landing on the top of the inflatable plyometric box. The inflatable plyometric box may additionally include a stabilizing member which may be connected to the bottom of the inflatable plyometric box, wherein the stabilizing member is adapted to increase the stability of the inflatable plyometric box.

A training device can easily be affixed or mounted to the hitting face of a golf club. The training device may provide auditory, tactile, and directional feedback for the user during practice so that he/she may learn how to strike the ball consistently on the sweet spot. A training device may include several raised surfaces of varying shapes rising from the base surrounding an aperture centered over the sweet spot of the golf club and larger than the surface area contacted by the ball. Use of the training device may reduce the user's variance from the “sweet spot” due to a strike not only along the longitudinal axis but also along the vertical axis. The user avoids impingement with the raised surfaces of the training device by striking the ball within a pre-set tolerance as well as within the boundaries of the aperture.

A golf club head includes a body having a recessed channel formed in the outer surface. A weight assembly that includes a weight disposed within the recessed channel and a cover extending over the recessed channel. A shelf is defined in the cover and slidably receives the weight. The weight assembly also includes a fastener coupling the cover to the body. The fastener is adapted to retain the weight in the recessed channel only indirectly by the cover. The cover is positionable in an unlocked configuration whereby the cover is raised at least partially out of the recessed channel and the weight is slidable within the shelf and the recessed channel, and a locked configuration whereby the cover is disposed within the recessed channel and the weight is secured within the recessed channel and the shelf. The weight moves with the cover between the unlocked configuration and the locked configuration.

A golf club head includes a body having an outer surface with a recessed channel formed therein. A weight assembly that includes a weight at least partially disposed within the recessed channel, a cover extending over the recessed channel, and a fastener coupling the cover to the body. The fastener is adapted to retain the weight in the recessed channel only indirectly by the cover. The weight assembly is selectively positionable between at least three configurations: a first configuration where the weight is secured within the recessed channel; a second configuration where the weight is slidable within the recessed channel; and a third configuration where the weight is completely removable from the golf club head. The cover is coupled to the body in all three configurations.

A golf club head includes a body having an outer surface and a recessed channel defined in the outer surface of the body. A chamber is defined at one end of the recessed channel. The golf club head also includes a weight assembly having a weight at least partially disposed within the recessed channel and configured to slide therein. A cover having a first end and an opposite second end, the second end including a projection, and a fastener coupling the first end of the cover to the body. The fastener secures the first end of the cover to the body while the projection of the second end of the cover engages with the chamber of the recessed channel to retain a position of the weight within the recessed channel between the first end and the second end of the cover.
