A pelvic floor pain relief device for use by humans. The device is spherical, and comprised of three layers. The core of the device is a compact compressible spherical core, having a compressibility rating sufficient to substantially support the weight of a human sitting thereon while allowing but minimizing the deformation of the sphere under the human load. A strengthening layer, consisting of randomly wound filament material, is wound around the exterior of the compressible spherical core to further minimize the deformation of the sphere in use. Finally, an exterior protective layer retains the filament of the strengthening layer in relation to the sphere and provides a cleanable surface. The method of use of the device is also disclosed.

A golf club with a multi-material face is disclosed herein. More specifically, the golf club head in accordance with the present invention has a multi-material striking face portion that is made out of a backing layer having a frontal pocket, made out of titanium, and an insert, made out of a composite material, adapted to be inserted into the frontal pocket. The frontal pocket and the insert could have complementary dovetail shaped undercut features to create a mechanical bond between these two components.

A protective rowing device for compression of the abdomen is provided that comprises a brace and U-shaped support member that may connect to a rowing machine seat and rail.

A floatation device is provided. In some embodiments, a floatation device is provided, comprising an inflatable ring composed of a transparent material, wherein the inflatable ring includes: an outer air chamber having a first valve for inflating the outer air chamber; an inner air chamber having a second valve for inflating the inner air chamber, wherein the outer air chamber and the inner air chamber are not in communication; a cut through the outer air chamber and the inner air chamber of the inflatable ring that forms opposing ends of the inflatable ring; and a plurality of fasteners placed on a top surface and a bottom surface of the outer or inner air chamber for detachably connecting the opposing ends of the inflatable ring.

The present disclosure relates to an inflatable structure transformable between a deflated state and an inflated state. The inflatable structure comprises a drop stitch fabric having a first layer and a second layer tethered by drop stitches. The inflatable structure is provided with, along at least a portion of an edge of the drop stitch fabric, an edge fixation line and an at least first inner fixation line at an at least first margin from the edge, the edge fixation line and the at least first inner fixation line comprising coupling means fixating the first layer to the second layer. The inflatable structure is further provided with, between the edge fixation line and the at least first inner fixation line, a non-inflatable connectable element e.g. adapted to be connectable with a detachably attachable counterpart element.

A shock absorbing system for force attenuation, impact modification or reduction, employs an envelope having a chamber containing a first working fluid, the envelope deformable in response to the impulse to attenuate impact force. A plurality of resilient supplemental absorber elements dispersed within the chamber. The plurality of resilient supplemental absorber elements are deformable in response to the force to assist in attenuating impact force and provide additional resilient restoring force to return the envelope to a pre-impact shape. In alternative implementations, a unitary cell for energy dissipation employs an envelope having a chamber containing a first working fluid and an inner element contained within the chamber and having an inner chamber containing a second working fluid.

Aspects provide a punching bag formed by a body panel with a first edge that forms a first closed end, and a second edge distal to the first that defines a second opened end of an interior enclosure of the punching bag that is bounded within interior surface sidewalls of the body panel between the first closed end and the second opened end. The first closed end traps air within the interior enclosure that is configured to interact via the second opened end with ambient air within an outer area surrounding the body panel, to thereby slow motion of the punching bag as it is conveyed through the ambient air in response to forces imparted to the bag body panel by a user.

A training device having a platform for receiving at least one person; at least one anchoring point for fastening a securing means that secures the person on the training device; a vertical rotation axis Z, about which the training device can be mounted rotatably or is mounted rotatably. The anchoring point is arranged at or above the height of the buttocks region of the person, and the training device is rotatable about this rotary axis Z by means of forces acting on the platform.

The present invention relates to a novel fitness weight device designed to allow users to customize dumbbell weights by filling the air chambers with air. The device comprises a dumbbell-styled weight with an inflatable air chamber. The devices can be inflated via a push button. Users can inflate the dumbbell devices to a desired weight for customized workouts. Once finished, the user can activate the air release valve to compact or retract the dumbbell for storage.

A pressing toy made of silicone is disclosed, including a first hollow housing and a second hollow housing that can be assembled into a housing body. The inner cavity of the first hollow housing and the inner cavity of the second hollow housing are assembled to form an inflatable chamber. The outer peripheral wall of the housing body is provided with a number of elastic protrusions that protrude outward. The elastic protrusions are of a hollow structure, and the inner cavity of each of the elastic protruding protrusions is communicated with the inflatable chamber. By pressing the housing body, some of the elastic protrusions are raised, or some elastic protrusions can be pressed so that some other elastic protrusions are raised, thereby creating a visual feedback of the deformation caused by the pressing action.
