The shallow water volleyball net anchoring system may be inserted into the ground to hold a pole for a volleyball net. The shallow water volleyball net anchoring system will generally be used in pairs of two to hold each end of a volleyball net. The anchoring system incorporates a sliding hammer that eases the task of driving the anchoring system thru the shallow water into the ground. The same sliding hammer may also be used to remove the anchoring system from the ground. With the anchoring system in the ground, a pole of a volleyball net may be placed in a central hole on the top of the anchor system and the anchoring system will hold the pole erect and stable.

Apparatus and rules for playing a boules-style game. The apparatus may include one or more rigid gamepads on which balls can roll, each gamepad having a raised ridge around its periphery defining a base area, and shapes formed in the base area by raised ridges enclosing one or more additional distinct areas. The game may be played in an open area with one or more gamepads placed on the ground. Gameplay includes players rolling the balls onto the gamepad from a distance. Each gamepad may have a post affixed thereto extending vertically from the gamepad. A bonus ball may be balanced atop the post, subject to being dislodged and awarding bonus points. Points are awarded based on a predetermined point value of the base area, and higher predetermined point values of the areas defined by the raised ridges, and the final positions of the balls.

A portable multifunctional gaming apparatus may comprise a pair of poles, and each of the poles has a main body, a lower end, and an upper end. The pole can be held by a user or mounted into a portable base through the lower end to firmly stand on the ground. Moreover, the lower end of the pole can connect to an extending pole to extend the length of the pole for different activities, and a sliding groove is formed at the upper end of the pole. Furthermore, a plurality of peripheral grooves are formed on a surface of the pole for receiving winding ropes. The base configured to steadily stand on the ground has a receiving hole at an upper end to receive the pole, thereby used for different games.

An isometric exercise apparatus adaptable to an existing treadmill or similarly shaped platform provides a height-adjustable bar assembly and rigid supporting pole portions. The horizontal bar is vertically adjustable by selectively unclamping and sliding the bar along the vertical bars. The apparatus may be adjusted and secured in various positions for singular or combined use with the treadmill. The mounting means of the apparatus to frame portions of the treadmill allows for easy disassembly and storage of the apparatus in a closet or under a bed.

A pivoting soccer goal mounted on a turntable can rotate so that a ball directed at the goal from nearly any angle will rotate the goal so that the ball will go into the goal. The goal can be seated in a standard golf cup and so can be used on a golf course. In another embodiment, the pivoting soccer goal can be mounted on a mat and set on any suitable field without the need for any holes in the ground.

Device for switching over the operating mode of a dynamic pylon for dances comprises as follows: the latch (2) at least one detail of pylon assemble with main recess (1) for the latch (2) at least one detail of another pylon assemble with counter-recess (8) for the latch (2) one magnet lock comprising at least one permanent magnet (7), whereas the main recess (1) for the latch (2) performed opened from the side of its lateral wall towards the outer space around the pylon detail wherein the main recess (1) is located, whereas the latch (2) is a member of the magnetic lock (the second or the third one). Switching over the mode of pylon operation is possible without interrupting the performance of exercises.

A starting block lock having a clamp, top and bottom locking wedges, and a rod is provided. The clamp includes top and bottom portions each having an inside surface and a body between the top and bottom portions. The body includes a cylindrical bore extending on a longitudinal axis between the top and bottom portions. The top and bottom locking wedges each include an outer surface, an inner surface, a side surface, and an aperture extending between and through the outer and inner surfaces. At least a portion of each of the side surfaces slidably contact the inside surface of the clamp. The rod extends through the apertures and the cylindrical bore and is configured rotate in a first direction to linearly displace the top and bottom locking wedges toward each other thereby providing an outward force against the inside surfaces of the clamp to expand the clamp.

A power rack adjustable telescopically in height, width and depth to work in conjunction with any barbell lift and any weightlifting equipment a first upright subassembly, a second upright subassembly, a third upright subassembly and a fourth upright subassembly. A first lateral subassembly is releasably connected to the first and second upright subassemblies. A second lateral subassembly is releasably connected to the first and fourth upright subassemblies. A third lateral subassembly is releasably connected to the second and third upright subassemblies. A weight safety catch is releasably mounted on each of the first and second upright subassemblies. The first and second upright subassemblies define an adjustable height of the power rack, the first lateral subassembly defines an adjustable width of the power rack, and the second and third lateral subassemblies define an adjustable depth of the power rack.

An exercise device for use when a person is in a pool or other water body. A central boom extends from attachment to a sidewalk around the pool, and extends to a wishbone member that forms a furcated member mounted to the central boom. The wishbone has lateral members that are parallel and spaced with hand-grippable handles at the ends farthest from the central boom, and disposed over the water. A user can grasp the handles and perform numerous exercise movements while buoyed, at least partially, by the water. A lower support member is mounted to the central boom beneath the wishbone, and a handle is mounted to the central boom between the wishbone and the lower support member. The user can rest his shoulders on the lower support member and hold the handle mounted to the boom, and perform abdominal exercises. Many other movements are possible.

A goal post retention device, comprising a body having a first member and a second member, wherein the first and second members are integral with one another, the first member comprising a first semi-open cylinder having a top planar annular surface, the cylinder having a first outer diameter, the second member arranged beneath and concentric with the first member, the second member comprising a semi-open cylinder having a second outer diameter which is larger than the first outer diameter, the semi-open cylinder having a bottom rim and a frustoconical inner surface extending upwardly from the bottom rim, the semi-open cylinder having a top annular surface. In one embodiment, a pike extends downwardly within the second member, extending slightly below the bottom rim.
