Abstract: A surgical support apparatus comprising a surgical boot sized to receive a portion of a limb of a patient therein and a tightening device positioned between a first end and a second end of the surgical boot. The tightening device is configured to apply a clamping force to the portion of the limb of the patient positioned in the surgical boot.

Abstract: The mini crampon is secured to a ski mountaineering/AT boot containing a special binding insert molded into the sole of the AT boot, and at least two trunnion pins, and at least one stop bumper retained in the mini crampon, which engage the binding insert in the AT boot sole securing the mini crampon to the AT boot.

Abstract: A heel traction aid (HTA) includes a gripping pad and a traction device having an upper surface, where the gripping pad includes a receiving bore penetrating the gripping pad and a raised ring encircling the receiving bore. The traction device is disposed in receiving bore such that the upper surface is disposed below the raised ring. The HTA includes a heel cup attached to lateral edges of the gripping pad, a first strap attached to the heel cup and including a first hook, and a second strap attached to the heel cup and including first holes. The first and second straps have elasticity sufficient to maintain tension when a heel of a shoe or foot is positioned in a concavity formed by the gripping pad and the contoured heel cup and when the first hook is engaged with one of the first holes of the second strap.

Abstract: An ice crampon for mountain climbing comprising a reinforcement 12B with a metal reinforcement, fitted with anchoring teeth 14, and a fastening device 30 comprising a lateral operating lever 32 forming a toggle joint for locking or unlocking the heel of the shoe along the pivoting direction of the operating lever 32.

Abstract: An anti-balling system for a crampon (10) to prevent balling and snow accumulation during snow and ice climbing includes a plate (46, 50) attached to the bottom of the crampon. The plate can be rigid and can have a lower surface (54, 58) formed of a material configured to prevent sticking of snow or ice to the lower surface of the plate. The plate can include at least one loop (62) integrally formed at a front of the plate to receive a front point (38) of the crampon. The plate can have a loop or window (96 or 232) to receive the center strap (22 or 220) of the crampon. The plate can be attached with bail ends (222 and 224) of a bail (214). The lower surface of the plate can include a plurality of protrusions (100) extending therefrom forming a plurality of raised section (104) and a plurality of edges (108) forming a nonskid surface configured to prevent the lower surface of the plate from sliding with respect to another object.

Abstract: The thick-walled cylindrical portion 12 of a holder 10 is provided with axial grooves 18 that open to the inner peripheral surface. In the axial grooves 18, slip-off preventive projections 20 are radially inwardly elastically urged by their own elasticity. The substantially disk-like antislip portion 54 of an antislip body 50 is centrally formed with a cylindrical antislip body-associated fitting portion 56 projecting downward therefrom. The antislip body-associated fitting portion 56 is formed with a circumferential annular slip-off preventive groove 58 disposed somewhat above the lower end thereof. The antislip portion 54 is formed with antislip body-associated insert receiving portions 60 extending therethrough and disposed at positions corresponding to the slip-off preventive projections 20. Once the antislip body-associated fitting portion is fully to the holder-associated fitting portion, the antislip body can be easily and reliably held in the holder without using any tools.

Abstract: A boot traction device or adapter that can be attached to the bottom of a person's footwear, which is removable, adjustable as well as lightweight. In manufacturing the present invention, a single style of sole plate can be configured for either a right or a left foot. The device can be adapted to fit onto any size of shoe or footwear and adjustable strap connectors are used to secure the adapter to the footwear. Threaded openings are provided for the attachment of gripping cleats or other devices to the adapter. Furthermore, the design of the adapter is such that an optional heel plate can be connected to the sole plate.

Abstract: A removable ice cleat for an outer frame member of a snowshoe provides traction for snow packed and icy conditions. For looser conditions including powdery snow, the ice cleats are quickly removable thus making the snowshoe versatile for all weather conditions. The ice cleat is attached using a metal band clamp that is tightened by a screwdriver or nut driver thereby making deployment of the ice cleats possible while outdoors. The ice cleat has an ice pick that is clamped by the band to the bottom of the outer frame member of the snowshoe. Several ice picks can be clamped in this manner. The picks have legs that extend downwardly and outwardly from a mid portion thereof to pointed ends having a generally triangular shaped penetrating portion that maintains good penetrability even as the pointed end becomes dull.

Abstract: The novel portable ice walking assistance device comprises a plurality of main horizontal plates. Each of the plates have foldable vertical end pieces at one end of the main horizontal plates. The main plates are attached together to form a three sided device that can be positioned on the sole of the user's shoe. A pair of the devices is used by an individual. Each of the horizontal plates have a plurality of small vertical prongs to assist in the gripping capability in ice conditions. A quick release mechanism is connected to one of the vertical end pieces to permit attaching to the shoe and ease of release of the device.

Abstract: A shoe containing a cushioned sole assembly includes in one embodiment a spring cushion feature inserted between two flexible hinged sole segments and in a second embodiment a spring cushion fastened to an adjustable hinged spring mounting plate. The cushion assembly can be a part of the shoe manufacture or the assembly can be a separate unit fastened and adjusted to the sole of a shoe by clamp brackets. The sole cushioning assembly can be adapted for any tipe of shoe including jogging and other athletic shoes, protecting the feet of joggers and others from injuries that occur during use on hard surfaces, shoes for workers, providing comfort for those who must stand on hard surfaces for many hours during a day and insulating the feet of the user from surfaces that have extreme hot or cold temperatures.
