A portable floating hot tub that is easy to assemble and take down and can be used in environments with extremely cold and turbulent water. The hot tub has three main components: a collapsible frame made of connected rigid members, an insulated liner sized and shaped to closely fit against the deployed frame and form a subassembly, and an inflatable pontoon that may have a central aperture for receiving the subassembly. The pontoon is first inflated and placed on the body of water, after which the frame and liner subassembly are placed over the central aperture. Filling the internal volume defined by the insulated liner with water causes the subassembly to descend within the pontoon. Cooperating means on the subassembly and / or pontoon prevent the subassembly from passing completely through the central aperture. A source of heated water such as a portable heater having a heating capacity of at least 30,000 BTUs rapidly heats up the water within the hot tub. The system components can be transported in one or more carry bags of less than 100 pounds and deployed and taken down by one person in an extremely small space, such as on a boat.

A frame of a shelving apparatus includes a plurality of vertical posts, a plurality of cross members, and a plurality of shelf supporting beams. Each vertical post has an inner attachment surface, a side surface, and a plurality of attachment slots formed at the inner attachment surface. Each shelf supporting beam includes a beam member and two post lockers provided at two ends of the beam member respectively. Each post locker includes an extension wall biasing against the side surface, a locker wall biasing against the inner attachment surface, and a locking element provided at the locker wall to to selectively engage with one of the attachment slots so as to detachably couple the shelf supporting beam between the vertical posts at a position that the beam member is extended between the side surfaces of the vertical posts.

A belt mounted infant carrier support device comprising a belt clip, an attached upward projecting hook-like protrusion upon which the lip of an infant carrier rests and a support cross member below the hook.

A solid frame orthotic seating device for use in a sling seat that is supported by solid rails, such as a wheelchair. The solid frame orthotic seating device comprises a solid, rigid, non-collapsing, and durable interior skeletal frame with an elevated anterior wedge sloping down to the top surface of the frame, lateral well support arms, and a posterior well. The frame dimensions are designed to place the user's hips into flexion, position the user's pelvis in a neutral to anterior position, and position the user's buttocks into and or below the posterior well. The anterior wedge supports and distributes the weight of the user's body away from the buttocks. The strength and design of the solid frame uniquely promotes proper positioning, and helps to anchor the user by positioning their buttocks into and or below the posterior well and or below the solid lateral well support frame.

The present invention is directed to a trash bin, namely an enclosed trash bin having a top and front doors that swing open on a hinged system. The enclosed trash bin contains a detachable cart in which trash and / or trash cans can be placed upon for storage and the cart can be detached from the rest of the trash bin and wheeled to the curb on trash pick-up day. The wheeled cart can either be removed from the inside of the trash bin or makes up at least one portion of the trash bin so that when it is removed it is brought to the curb with at least one portion of the cart. When the cart is returned to the trash bin and placed inside of the bin the trash bin is then whole and impermeable to raccoons and other animals and / or rodents.

A stator for an electric rotating machine has iron core fastening members on the outer circumferential surface of a stator iron core, spaced apart from one another in a circumferential direction and fastened to the iron core in an axial direction. Holding rings on the outer circumferential surface of the iron core, spaced apart from one another in the axial direction, press the iron core toward a center portion thereof via the iron core fastening members. Ring-shaped inner frame members protrude from the inner surface of a frame that encloses the iron core, and are spaced apart from one another in the axial direction. Elastic supporting members are fixed to the inner circumferential surfaces of the inner frame members that are adjacent to one another, and are fixed to the outer circumferential surfaces of the holding rings at the middle in the axial direction, or vice versa.

The invention relates to a boomerang that can automatically change both elevation angle α of blades and curve radius r of blades upon the change of rotary speed of blades (12), wherein blades (12) are made of elastically plastic film preferably selected from a group of polyvinyl chloride, polypropylene, polyethylene terephthalate, polystyrene and high impact polystyrene, the material has a specific weight of from about 0.9 g / cm3 to about 1.60 g / cm3 and as thickness from about 0.1 mm to about 1 mm; the ratio between the depth of the rear groove and blade width is from about 1 / 7 to about 6 / 7; the ratio between depth of the front groove and blade width is from about 0 to about 3 / 7; the elevation angle α0 is from about 10° to about 45°; the initial curve radius r0 of the blades is longer or equal to 1 / 5 of the radius R of said ring (13); the ratio between the total area of said blades and the area of a circle defined by said ring (13) is from about % to about 38%.

A headrest for a patient-bearing surface, having an approximately horseshoe-shaped form and comprising a central section (14) for supporting the back of the head or the forehead, the bearing surface thereof being at least approximately spherical shell-shaped, also comprising two side sections (16) which are arranged at a distance from each other and whose bearing surfaces conform at least approximately to a common cylindrical surface whose axis is parallel to a symmetrical line (20) of the headrest extending between the side surfaces (16). A cheekbone support (18), which protrudes in the direction of the other side section (16), is provided on each side section (16).
