Abstract:

A garment in the form of a knee pad or elbow pad protects a wearer during athletic activities. A toughening patch is applied to the outer surface of a nylon shell with the application of heat and pressure. A mixture of Teflon powder and plastisol ink is applied to a release liner and is applied to the nylon shell with the application of heat and pressure. Excess ink is removed from the patch with a blotting paper to impart a relatively low coefficient of friction to the patch.

Appl. No.:

6/910632

Inventors:

Robert F. McDavid - Downers Grove IL

International Classification:

A61F 500

US Classification:

128 80C

Abstract:

A unilateral knee brace is provided with pliable, non-extensible tension members which are connected to the brace and are placed in tension and resist opening of the knee at the medial side of the knee. The preferred tension members are X-shaped straps which are crossed at the knee joint. More specifically, the knee brace has a hinged support including pivotally-connected upper and lower plate members extending above and below a wearer's knee. The hinged support is secured to the wearer's leg by upper and lower cuffs which encircle lateral or outside portions of the wearer's leg above and below the knee. The hinged support is positioned on a lateral or outside portion of the wearer's leg. The brace further includes a pliable support of non-elastic, stretch-resistant straps extending between the cuffs, and positioned opposite the hinged support on a medial or inner portion of a wearer's leg. Upper and lower free ends of the pliable support straps are connected to the hinged support plates.

Appl. No.:

8/931592

Inventors:

Robert Finley McDavid - Downers Grove IL

Assignee:

McDavid Knee Guard, Inc. - Chicago IL

International Classification:

A61F 500

US Classification:

602 27

Abstract:

An ankle restraint is made of plastic material and includes a pair of splint plates pivotally joined to struts of a stirrup member. Stops carried on the splint plates interfere with the range of motion of the struts, thereby limiting movement of the wearer's ankle. The stop members have faces engaging edges of the struts and have a height matching the thickness of the struts. Polypropylene or other plastic materials may be used to achieve a desired compromise between a desired flexural modulus and a desired impact strength.
