Abstract: Improvements in an adjustable dumbbell to adjust the weight by insertion and removal of weights to one or both sides of the dumbbell. The weights are loaded into a carousel around the outside of the dumbbell handgrip. The weights can be place in opposing axial arrangement or can be placed in an uneven loading. A locking mechanism allows for a single rotation of the locking mechanism to secure and unlock all weights with a single rotation. The locking mechanism prevents the weights from falling or dislodging from the dumbbell axle when the dumbbell is being used. A rotating central axil allows for the heavy side of the dumbbell to rotate to a lower position. The rotating axil creates an eccentric weight placement for dynamic inertia exercises where a user can rotate or spin the eccentric weight around the handle of the dumbbell.

Abstract: An exercise chair primarily directed to employing an exercise method, with foot bars, high bars, and a foldable configuration. The seat is supported by a plurality of support elements, at least some of which are hingeably connected with the seat, so that the chair can be folded into a compact shape for storage or transport. The independent foot bars may each be attached to a lever that is hingeably coupled with one or more of the support elements. The position of the foot bars may also be adjustable by extending out of the levers and locking into the desired position. One or more resistance elements may be removably attached to a location below the chair seat, and individually connected with the levers via an adjusting assembly that can either slide or be placed in pre-set mounting locations along the lever to provide variable resistance, or can be equipped with a turnbuckle to provide varying resistance.

Abstract: A passive motion exercise and/or treatment apparatus is provided which includes a main support assembly for supporting at least the head and torso of a user. The main assembly includes three support members which, in one mode of operation, are disposed in a common plane. The second and third members are movably connected to the first member, which is a backrest support member, and are movable relative thereto so as to respectively provide passive movement of both the head and, and the lumbar region, of a user. Cervical side bending and rotational movements and lumbar side bending and rotational movements can all be provided. A separable leg support assembly is adjustable to support the calves of the user in a plane elevated with respect to the common plane while the apparatus provides the aforementioned passive body movements.

Abstract: A lifting toilet chair having arm rests which are utilized to provide a leveraging action to allow the user to control the ascent and descent of a pivoting toilet seat as well as to assist the user in raising himself/herself from a sitting to a standing posture.

Abstract: There is disclosed an adjustable germicidal system to be attached to an air handling apparatus. In one embodiment, an adjustable germicidal system comprises a first socket assembly adjustably coupled to a second socket assembly. The first socket assembly and the second socket assembly may be spatially adjusted with respect to one another in at least one dimension. A germicidal lamp is coupled to each of the socket assemblies. The adjustability of the socket assemblies allows the lamps to be placed in a desired alignment relative to one another and relative to one or more walls of the air handling apparatus. A single power cord is coupled to one of the socket assemblies.

Abstract: A small reciprocating saw device is provided which is adapted for one hand operation and which enables delicate sawing or filing work to be carried out.

Abstract: A method and device are provided for producing a double roll fabric construction useful as a receptacle for, e.g., eyeglasses. The construction is comprised of adjacent rolled up portions disposed in side by side relation so as to be unrollable to form a receiving space therebetween. The rolling device includes a pair of spindles disposed in parallel relation and adapted to respectively receive opposite ends of a stretchable fabric so that rotation of the spindles causes rolling up of the fabric around the spindles. Respective pinion gears are mounted on the spindles and are disposed in engagement with, and ride along, a rack member. A drive unit produces movement of the pinion gears toward each other along the rack member so as to produce rotation of the second spindles and resultant wrapping of the fabric around the respective spindles to produce respective fabric rolls of the double roll fabric construction. After the construction is removed from the spindles, the ends are sewn to produce the receptacle.
