A trampoline anchor comprising a trampoline frame, a trampoline bed attached to the trampoline frame, trampoline springs connecting the trampoline frame to the trampoline bed, a fluid chamber formed as a toroidial enclosure, and an outside skirt attached to the fluid chamber, wherein the outside skirt connects between the fluid chamber and the trampoline frame at a fluid chamber skirt connection. The trampoline anchor can also have fluid chamber pods attached to the legs of the trampoline.

A ball pit apparatus for use with a plurality of balls. The ball pit apparatus includes: a base portion configured to provide a ball pit for holding a plurality of balls, wherein the base portion includes one or more inflatable side walls configured to, when inflated, extend around a periphery of the base portion; a roof portion configured to provide a ball chamber for holding a plurality of balls above the base portion; one or more inflatable supports configured to, when inflated, hold the roof portion above the base portion; a suction inlet configured to be in fluid communication with the ball chamber so that, when suction is provided at the suction inlet, suction is also provided to the ball chamber; a ball inlet configured to be in fluid communication with the ball chamber so that, when suction is provided to the ball chamber, a ball received at the ball inlet is drawn into the ball chamber. The roof portion includes an opening configured to face the base portion when the one or more inflatable supports are inflated. The roof portion includes at least one blocking element configured to block the opening so as to prevent balls from falling through the opening when suction is provided to the ball chamber and to not block the opening so as to allow balls to fall through the opening when suction is not provided to the ball chamber.

A sports helmet comprises a single-piece plastic shell, an occipital shock absorber attached to the inner surface of the shell in the rear region to at least partially overlie an occipital area of the head, an inflatable occipital pad removably attached to the inner surface of the shell in the rear region and positioned between the inner surface of the shell and the lateral padding assembly to push the occipital shock absorber forward when the occipital pad is inflated. The occipital pad comprises a top sheet and a bottom sheet bonded together, a plurality of inflatable pockets formed in the top sheet and fluidly connected through channels formed in the top sheet, a valve assembly for inflating the plurality of inflatable pockets, the valve assembly bonded to the bottom sheet. The valve assembly extends through a hole in the shell for inflation.

A training device for monitoring a physical exercise is formed having a volume element, a sensor apparatus which is designed to detect a mechanical force and/or a pressure which a user exerts on the volume element while performing the physical exercise, and to generate a measurement signal on the basis of the detected force and/or the detected pressure, and an evaluation apparatus which is designed to compare the measurement signal generated by the sensor apparatus with a value range and/or a target value and to automatically generate an output signal on the basis of the result of the comparison.

A wearable massage and/or compression device for applying controllable scrolling or intermittent sequential forces, such as compression forces, to the body and limbs of a user comprises one or more shape-memory wires integrated into an article of clothing and configured to apply a compression pressure to the limb through the fabric body upon changing shape in response to a stimulus, a pre-tensioning apparatus in the form of a bungee cord associated with each shape memory wire, and a micro-processor based controller for selectively actuating the one or more shape memory wire to reduce the length of the shape memory wire to thereby apply pressure to the wearer's body.

An apparatus for receiving one or more activity attachments including a deck having one or more openings along a long axis of the deck and between the top surface and the bottom surface of the deck. Each of the one or more openings having a circular aperture for receiving an accessory of a set of accessories. Each accessory of the set of accessories providing an activity for a user of the activity. Each accessory having an attachment platform configured to attach the accessory to the board. The attachment platform having a locking mechanism to engaging with a complementary locking mechanism of the board.

An inflatable exercise chamber (100) for performing exercise therein, the inflatable exercise chamber comprising (100); one or more walls (102) defining an enclosed space, wherein the wall (102) comprises an inner membrane (110, 210) and an outer membrane (112) defining an inflatable cavity (114) therebetween, wherein the inner membrane (110) of the wall is a gas-permeable membrane (210).

Aspects herein provide for an apparel item having an integrated parachute structure and a set of intake ducts. The parachute structure is configured to transition from a first slack state to a second inflated state subsequent to air entering the set of intake ducts incident to ground locomotion of the wearer thereby increasing air resistance to wearer movement.

An open field game arrangement includes glowing targets and provides responses, such as lights and sounds, when the targets are hit.
