Abstract: An agility ladder includes a plurality of rungs, a left link assembly disposed between each rung and including ends pivotally attached to left ends of each rung, a right link assembly disposed between each rung and including ends pivotally attached to right ends of each rung, and first and second links included on each of the left and right link assemblies. The first and second links may be pivotally attached at a link pivot joint, where, through pivotal attachment of the left and right link assemblies with the plurality of rungs and pivotal attachment of the first and second links, the plurality of rungs are moveable from an open position where the plurality of rungs are spaced apart from one another to a collapsed position where the plurality of rungs are aligned adjacent to one another and are not overlapping with one another.

Abstract: An agility ladder has a plurality of rungs including first and second rungs. A left link assembly has ends pivotally attached to left ends of the first and second rungs, and a right link assembly has ends pivotally attached to right ends of the first and second rungs. The left and right link assemblies each include first and second links having equal lengths, with the first and second links joined at a link pivot joint which allows the first and second links to form an angle between them of less than 180 degrees.

Abstract: A floor exercise slider may have an attachment device on a side of a frame. A resilient pad is attached to an upper surface of the frame, with the resilient pad having raised blocks separated by grooves. A slide plate may be joined to a bottom surface of the frame. The raised blocks may be evenly spaced apart laterally and/or longitudinally by the grooves. Two sliders may be attached via the attachment devices to form a slider assembly which can accommodate both of the user's hands or feet.

Abstract: A goal apparatus for soccer (football) and the like has a frame, a first pliable goalpost member, a second pliable goalpost member and a pliable crossbar member. The frame presents net connection points and is configured to support each of the pliable goal members in tension between two net connection points such that the goal apparatus presents a substantially rectangular goal mouth.

Abstract: A batting tee has a post including a ball holder on a top end of a post, and a tube cap on a bottom end of the post. A receptacle is positioned in a recess in a base frame having a through hole. The tee is set up for use by passing the post through the through hole from the bottom of the base and securing the tube cap to the base. The batting tee may be set up for use, and disassembled for transport or storage, quickly and easily.

Abstract: An energy absorbing ball has a spherical resilient shell having a smooth inner surface and a smooth outer surface. A fill material is introduced into the shell via a fill opening in the shell. The fill material includes a liquid and a solid particulate having a density greater than the liquid, and with the fill material substantially entirely filling the shell. A plug in the fill opening seals the fill material within the shell, optionally with a recess over the plug. The smooth inside and outside surfaces of the she are spherical and free of any projections or obstructions.

The frame presents net connection points and is configured to support each of the pliable goal members in tension between two net connection points such that the goal apparatus presents a substantially rectangular goal mouth.

Abstract: A miniature soccer goal has a frame including a front lateral tube, left and right upright tubes attached onto the left and right sides of the front lateral tube, left and right side tubes each having a front end attached at lower end of the left and right upright tubes, respectively, and a back end attached to a back lateral tube. Each of the front and back lateral tubes, and the left and right uprights and the left and right side tubes has a net slot leading into an internal channel. The internal channel may be formed by an arc section and side walls. A net is supported on the frame with edges of the net captive in the channels of the tubes. The frame has left and right net tubes attached to left and right back corners of the net and optionally applying tension to the net.

Abstract: An agility pole or a passing arc includes one or more receptacles adjacent to a first end of a tube. A spike assembly has one or more fittings, and a spike attached to a holder adapted to slide into the first end of the tube, in a spike-in position wherein the spike is within the tube, and in a spike-out position wherein the spike is substantially outside of the tube. The fittings engage the receptacles in the spike-in position and in the spike-out position. The agility pole or passing arc may be transported and stored in the spike-in position so that injury or damage from the spike is avoided.

Abstract: A field cone collector includes a tube attached to a handle. A pair of arms is pivotally supported at a lower end of the tube. A spring urges the arms into a first position wherein an end of each arm projects out of the tube. A linkage within the tube extends from the pair of arms to an upper end of the tube, optionally to a sliding trigger. Actuation of the linkage moves the arms into a second position wherein the arms are withdrawn towards or into the tube. A field cone may be collected by pushing the lower end of the tube through an opening in the field cone. The arms momentarily move inwardly as they pass through the opening, and then move back to the first or projecting position to hold the field cone onto the tube.

Abstract: A rebounder may include a frame having tubes in the shape of an isosoles trapezoid with rounded corners. A net is attached to the frame. A rear support may be pivotally attached to a top of the frame, and support bars attachable to sides of the frame and pivotally attached to the rear support. The rear support is movable from a folded position where the rear support is near parallel to, and/or with a floor tube of the rear support in contact with the frame. The rear support is also movable to an unfolded position where the rear support holds the frame and net at an acute angle to the floor or ground.

Abstract: A football throwing trainer has a football holder including first and second end caps adapted to fit over the ends of a football. Holder straps connect the first and second end caps and hold the end caps securely onto the ends of the football. A tether is attached to the first end cap and to a belt or cuff. The trainer allows a lone player to practice throwing a football and to easily retrieve the thrown football.

Abstract: An adjustable height hurdle may have a rigid base with a slider movable on or in a track to different base length positions. A flexible bridge may have a first end attached to the slider and a second end attached to the track. The bridge is movable from an erect position wherein the bridge is on a top side of the base and the hurdle has an isosoles trapezoid shape, to a collapsed position wherein the bridge is on a bottom side of the base. The height of the hurdle is adjusted by changing the length of the base.

Abstract: A golf swing training guide provides stationary markers or pads positionable in three dimensions, to assist in proper body position and golf club swing movement. The training guide has a telescopically extendible base pole pivotally attached to a base and positionable at a plurality of inclination angles relative to the base. A telescopically extendible touch pole is attachable to the base pole and may be pivoted relative to the base pole to position a pad on the touch pole into a desired position.

Abstract: Embodiments of the disclosure relate to a cartridge that includes slots for storing biosample capillary tubes. The cartridge has the same form factor as data tape cartridges to allow the cartridge to be handled by the same robotic mechanisms that handle data cartridges in an automated tape library. One aspect of the disclosure concerns a cartridge comprising an enclosure that includes a movable door to provide access to a tube holder in the enclosure. The tube holder includes cylindrical holes or slots for receiving capillary tubes which contain biosamples scanned and analyzed an automated tape library.
