Appl. No.:

12/814400

Inventors:

Phong Tran - Tarzana CA, US

International Classification:

A61F 5/00

US Classification:

602 16

Abstract:

An adjustable resistance joint brace with a pair of pivotally interconnected semi-flexible struts compressing a rubber disc washer to impart resistance during knee, elbow, ankle and hip flexion and extension. A manually adjustable knob controls the amount of resistance by squeezing together the upper strut, a rubber disc washer in between, and the lower strut. The brace includes a sleeve for housing the struts and the brace opposes movements when the struts articulate about a transverse axis corresponding to the anatomical pivot axis of the body joint of the knee, elbow, ankle, and hip. At the pivot axis, a turn of the knob clockwise tightens the brace and a counterclockwise turn of the knob would lessen the resistance. The brace has application for dynamic sports movements, daily routine movements, rehabilitation and weightlessness strength training.

Abstract:

An adjustable shuttlecock including means for attaching and detaching an interchangeable tail and a head including an interchangeable weight portion and an interchangeable springing mechanism. The springing mechanism and tail may be designed in such a way as to allow for proprietary designs and logos to be added to them. Additionally, the shuttlecock is designed from durable materials, which will help provide the shuttlecock with a very long life-span. Furthermore, the shuttlecock's spring may be constructed in such a manner as to cause a noise to be made upon compression.
