Hockey puck rebounders and training devices are capable of rebounding playing objects, such as hockey pucks or balls. Aspects of the technology are directed to training devices that can be used on ice surfaces or synthetic ice surfaces to practice various skills. The training device can include a frame, anchors, and rebound panels mounted to a tubular frame. The anchors can secure the training device to the ice surface. Hockey pucks can be rebounded off the rebound member by a player.

Shoulder exercising machines (machines) may include an upper member, a lower member, and a resistance member. The upper member and the lower member may be slidingly engaged with each other. The resistance member may provide resistance with respect to the upper member sliding against the lower member. The resistance member may be at least one elongate elastic member with two opposing terminal ends. The upper member may have at least one handle and an upper surface for supporting at least a portion of a forearm and/or a wrist of a user during exercises with the machine. The user may push or pull the handle and slide the upper member with respect to the lower member while experiencing resistance due to the resistance member.

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.

An exercise apparatus for performing one or more exercises is described. The exercise includes at least one support structure, one or more elastic bands, and a back support member. The one or more elastic bands is coupled to the at least one support structure at one end of the one or more elastic bands. The back support member is arranged in an inclined position such that a first end of the back support member is detachably coupled to the at least one support structure and a second end of the back support member is supported at a surface positioned at a height lower than a height at which the first end is positioned. The one or more elastic bands are configured to assist a user during one or more exercises, where the back support member configured to support a body of the user.

There is provided a system for hydrodynamic and/or air levitation of an object, such as a ball by a stream of water, and a striking object for hitting the object, and a method of play comprising the system.

A climbing action structure includes a support structure having a plurality of columns configured to be fixed relative to an underlying surface and support at least one header of a plurality of headers above the underlying surface. A climbing action space is defined between the columns, the headers, and the underlying surface that is devoid of intruding structure. The headers define a plurality of action element mounts, each defining a longitudinal axis substantially parallel to the underlying surface. At least one action element is removably coupled to the support structure at a respective action element mount. The action element includes a top end having a header connection member. The header connection member being coupled to the respective action element mount and adjustably positionable along the longitudinal axis, and the action element is disposed within the climbing action space and a participant has 360° access to the action element therein.

A golf ball retrieval apparatus for retrieving a golf ball from a cupped hole is provided. The golf ball retrieval apparatus comprises an outer tube and an inner shaft slidably receivable within the outer tube. A retrieval mechanism is mounted to the inner shaft and capable of releasably grasping the golf ball. A cam system is mounted to the inner shaft for substantially centering the inner shaft within the outer tube and impeding the movement of the inner shaft within the outer tube. Interaction of the cam system and the outer tube impedes movement of the inner shaft within the outer tube and releasably, frictionally secures a desired position of the inner shaft relative to the outer tube. Golfers are enabled to facilitate expedient retrieval of a golf ball from a cupped hole or other location while remaining in a substantially upright position.

A device and method of learning and training of the golf swing that is based on the performing of the swing as a continuous exercise, where the person, either a student in learning or a player in training, performs continuous movements or golf swings without depending on the presence of the ball on a ball placement site, in which the device places the ball on the ball placement site in a programmed or random way without making the person stop the succession of continuous swings.

The subject invention comprises a system, and method of using the system, for providing improved alignment in multiple settings. Appropriate settings include woodworking, machining, and sports, although there are several other practical applications for this technology. The invention employs one or more alignment stations that have a base plate that anchors into a flat surface, guides that fit into the base plate, a top rotating element that fits onto the base plate secures the first set of guides into place, and a positional lock that locks the rotating element into place relative to the base plate.

A sensor, sensor system and methods that measure surfer metrics and ride data and display the data.
