Abstract: Concrete finishers' knee skis provide a support for a cement finisher to move across wet cement, either kneeling or standing on the skis. Each ski is formed of a elongated sheet stainless steel body with upturned ends and with side walls, both bent with a curvature radius of about 1/2 inch. In one upturned end is a stirrup cage having a top opening to receive the shoe toe or a worker in a kneeling position, and a second side opening to receive the toe of the worker in a standing position. The ski is thus pulled and pushed only by the shoe toe, and may be moved forward, backward, or sideways without indenting or otherwise damaging the surface of the finished cement.

Abstract: A dynamic patellar brace useful for both diagnosis and treatment of patellar subluxation. The patellar brace includes a patellar bracing pad adapted to be positioned laterally with respect to the patella and to apply medial pressure to the patella to prevent subluxation for all normal ranges of knee flexion and motion. The patellar brace may be used to facilitate positive diagnosis of patellar subluxation whose symptoms may mimic other pathological problems of the knee and, therefore, lead to an erroneous diagnosis. The brace may also be used for treatment and/or to delay or avoid the need for corrective surgery.

Abstract: For both orthopedic and sports uses, a foamed plastic pad is integrally molded to a fabric. More particularly, a knitted sleeve is constructed having a terry loop on the interior surface of a hydrophobic yarn (e.g. acrylic) and an exterior surface of a hydrophilic yarn (e.g. cotton), whereby moisture is wicked away from the surface in a hydrokinetic fashion. A soft, hydrophilic polyurethane foam pad, which acts as a sponge, absorbs the moisture, is molded integrally with the sleeve, leaving the terry loops free for skin contact. For sports uses, knitted or woven fabrics may be employed, and stiffer, polyurethane foams are preferred.

Abstract: A knee brace including an elastic sleeve stretchable in a circumferential direction, a plurality of individual pad mounts permanently fixed to the interior of the sleeve which are disposed in a generally circular array to surround a substantial portion of the wearer's patella, and at least one resilient pad selectively removably engageable with different of said individual pad mounts for selectively removably mounting the pad at different positions relative to the wearer's patella to provide patella support at selectively variable positions as dictated by the individual needs of the wearer.

Abstract: A knee brace including an elastic sleeve stretchable circumferentially, a flexible sheet non-stretchable in a circumferential direction secured to the interior of the sleeve configured and dimensioned to surround a substantial portion of the user's patella, and a resilient pad stretchable at least circumferentially secured to the flexible inelastic sheet. By reason of the inelastic characteristics of the flexible sheet to which the resilient elastic pads are mounted, the pads are not circumferentially displaced or dislocated from their normal position proximate the periphery of the patella when the knee is bent and the elastic sleeve stretches circumferentially. Thus, patella support and protection is maintained regardless of the extent of knee flexure.

Abstract: A protective pad for use in cushioning the body has a resilient organic foam polymeric material with body cushioning properties. The pad has an undersurface facing the body and a scored top surface forming an increased flexibility in the pad to better enable it to conform to the joint or other body area which it is protecting. This increased flexibility and body conforming property is obtained without substantial loss of body cushioning and protective properties.

Abstract: A support for encircling the knee to give support and protection to both the skeletal and muscular structure of the joint. The support includes a tubular device having several separate resilient protective pads attached thereto. A patella cover pad member is positioned on the anterior side of the support to cover and protect the patella and its retinaculum. Medial and lateral pad members are positioned on the strap to engage the knee, extending rearwardly over medial and lateral sides thereof from the patella cover member. The posterior surface of the knee is covered by a flexure pad member. The several independent members allow flexion and extension of the leg while providing both support and protective padding for the knee joint.

Abstract: A pair of cuffs are positioned on the thigh and calf respectively adjacent the knee joint. Each of these cuffs encloses and is backed by a fluid-filled chamber made of a flexible resilient material. The inner surface of this chamber is bonded to an elasticized fabric band which encircles the leg and positions each of the cuffs immediately adjacent the knee joint.An accordion-folded section of tubing extends from the upper to the lower fluid filled chamber along each side of the knee forming a unitary fluid-filled system. A pair of flexible but inextensible straps overlays each of the accordion-folded tubes and is securely fastened to the cuffs. Upon lateral impact, fluid migrates from the side of the knee which has been struck to the opposite side causing the cuffs to firmly grip the thigh and calf, and the accordion-folded tube on the opposite side to fill with fluid, creating compressive force between the knee joint and the tensioned straps and preventing dislocation of the knee joint.

Abstract: A knee brace is disclosed including an elastic sleeve configured to snugly embrace the user's knee region. The sleeve is provided with an opening in the front for the patella. A drawstring slidable in a two-way stretch elastic casing stitched to the margin of the opening facilitates adjustment of the circumference of the opening to snugly engage patellas of different sizes and/or shapes. Lateral pads disposed on either side of the patella opening and a vertical pad disposed above the opening are also included. Adjustable fasteners between the pads and the sleeve interior permit the horizontal spacing between the lateral pads and the center of the kneecap opening and the vertical spacing between the upper pad and the center of the kneecap opening to be varied to accommodate different sized patellas.

Abstract: The article is a combination of a protective pad, a cover element and two elastic strips. The protective pad is somewhat wider than it is long. The top and bottom edges of the pad are substantially straight, while the central portion of each side edge is cutaway, leaving two protrusions at the opposite ends of each side edge. The cutaway opening in each side edge extends a substantial distance into the pad, and a further keyhole-shaped opening, central of the cutaway opening, extends even further inwardly of the pad. The pad is covered with the stretchable fabric cover element, which follows generally the outline of the pad. The two strips of elastic connect the opposed side edges of the pad-cover combination at each end thereof, with the elastic strips being sufficiently short that they tend to draw the sides of the pad-cover combination toward each other, thereby curving the surface of the combination so that it will conform to the user's limb.

Abstract: The invention relates to a protective device adapted to protect the elbow or knee of a person while engaging in various sports and work. The device is constructed from a resilient energy-absorbing material such as plastic foam and comprises a generally rectangular planar member which can be cut or stamped from a sheet of plastic foam. One side of the planar member comprises a flap member adapted to be flexed together with corner ends of the side, and held together by a flexible cord to form a cradle section adapted to cradle the knee or elbow when worn and secured thereon by a strap member.

Abstract: The present protector includes a tubular sleeve which is stretchable in both longitudinal and circumferential directions and is adapted to provide a snug fit over the arm or foot of the patient and a pad carried by the sleeve. The pad is of substantially U-shaped transverse cross-sectional configuration and substantially V-shaped longitudinal cross-sectional configuration so as to receive and cushion the patient's elbow or heel therein. The pad includes a pair of opposite side panels defining opposite sides of the U-shaped transverse cross-sectional configuration and a pair of superpositioned substantially rectangular bottom panels providing additional padding in the central portion and defining the V-shaped longitudinal cross-sectional configuration.
