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.

A padded punching surface incorporating elastic roping connected to a frame which allows the punching surface to be struck with a force of impact by a user so as to minimize swinging of the punching surface. The apparatus is an improvement on existing punching bags which enables easier convenient and more realistic combat training for athletes and users. The amount of swing for the punching surface can be adjusted by tightening or loosening the elastic roping. The punching surface can include an attached head shaped surface for more realism.

Shoulder exercising machines (machines) may be disclosed. Such machines might 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 have a 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.

An apparatus for improving flexibility and its method of use are provided. The apparatus features a flexible member, which can have varying degrees of stiffness and flexibility, based on user preference. Further, the apparatus features a first and second auxiliary grip, as well as a first and second primary grip. In conjunction, these grips provide a vast multitude of ways to grip the apparatus, enabling it to be used in a wide variety of stretches and exercises, promoting strength as well as joint mobility and flexibility.

An apparatus and method of indicating the ball center of gravity position. The method of indicating the ball center of gravity position includes the following step of: moving the ball to a rotating member of a rotating device; driving the rotating member to rotate the ball along a axis of rotation of the rotating device, and adjust the center of gravity of the ball corresponding to the position of the rotating device; moving the ball onto a first carrier of a first transport device; and marking an identification mark on a predetermined area of the ball.

The apparatus includes a light emitting pace rope positioned under water that shows where the swimmer should be to move at a selected pace. The LED rope includes a ribbon cable with ground, power and control wires. Equally space LEDs are attached to the ground and power wires along the cable. The cable and LEDs are received in a transparent plastic tube couplers are attached to the cable ends. The plastic tube is encased in transparent silicone. Ends of the LED rope are attached opposite pool end walls. A power supply is connected to a coupler. A micro-controller provided signals to the control wire which provides additional power to illuminate the LEDs one at a time at the selected pace. Additional LEDs are provided to continue the pace in the opposite direction.

A nose clip structure includes a nose frame and nose pads. The nose frame includes two arms and a connecting portion. The connecting portion interconnects the two arms to make the two arms bend flexibly. The nose pads are disposed on the two arms of the nose frame, and has an anti-off body adapted to engage with the wing of the swimmer's nose for preventing falling-off of the nose clip structure.

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.

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 arcade game system includes a frame that is made from an arrangement of pivotally connected panels that are formed from an assembly of struts arranged in a planar configuration. The frame includes a rear panel, a front panel, and a first and second body panel. When the frame is in an unfolded configuration a game play area is defined between the rear panel and the front panel and above the first body panel and the second body panel. The frame may also be arranged in a collapsed configuration in which each of the rear panel, first body panel, second body panel, and front body panel are parallel to each of the other panels to form a stack of panels.
