Abstract
Abstract A hand brake for a wheeled vehicle comprises an operating shaft carried within a sleeve affixed to the frame of the vehicle to accommodate axial displacement and rotation of the shaft attendant to shifting the brake between respective braking and non-braking positions. A locking lug on the shaft is adapted to engage and secure a receiving member mounted on one of the vehicle wheels upon rotational and axial movement of the shaft into the braking position, and stops on the shaft cooperative with the sleeve to releasably secure the shaft in the respective braking and non-braking positions.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
176 words
A braking arrangement for a vehicle wheel rotatably mounted on the axle of a wheeled vehicle, comprising: receiver means affixed to the vehicle wheel; stationary mounting means spaced from said receiver means along the axis of the wheel affixed to one side of the axle; an operating shaft extending through the axle carried by said mounting means, said mounting means accommodating movement of said shaft along and rotationally about its axis attendant to shifting the brake between respective braking and non-braking positions; lug means on said shaft extending from the periphery thereof perpendicularly to the axis of the shaft and being engageable with said receiver means to arrest rotation of the wheel upon rotational and axial movement of the shaft into the braking position and disengageable with said receiver means upon rotational and axial movement of the shaft into the non-braking position; biasing means mounted on the side of the axle opposite said mounting means urging said shaft toward the braking position; and retaining means releasably securing said shaft in the respective braking and non-braking positions.
Claim 2
Dependent Claim
176 words
A braking arrangement for a vehicle wheel rotatably mounted on the axle of a wheeled vehicle, comprising: receiver means affixed to the vehicle wheel; stationary mounting means spaced from said receiver means along the axis of the wheel affixed to one side of the axle; an operating shaft extending through the axle carried by said mounting means, said mounting means accommodating movement of said shaft along and rotationally about its axis attendant to shifting the brake between respective braking and non-braking positions; lug means on said shaft extending from the periphery thereof perpendicularly to the axis of the shaft and being engageable with said receiver means to arrest rotation of the wheel upon rotational and axial movement of the shaft into the braking position and disengageable with said receiver means upon rotational and axial movement of the shaft into the non-braking position; biasing means mounted on the side of the axle opposite said mounting means urging said shaft toward the braking position; and retaining means releasably securing said shaft in the respective braking and non-braking positions.
Claim 3
Dependent Claim
27 words
The invention according to claim 1, and said shaft extending through said mounting means along an axis extending generally perpendicular to the rotational axis of the wheel.
Claim 4
Dependent Claim
27 words
The invention according to claim 1, and said shaft having a normally projecting handle portion dimensioned to overlie said wheel in the braking position of the shaft.
Claim 5
Dependent Claim
16 words
The invention according to claim 1, and said receiver means being a toothed sprocket-like member; and
Claim 6
Dependent Claim
11 words
said lug means being engageable with the teeth of said sprocket.
Claim 7
Dependent Claim
11 words
said lug means being engageable with the teeth of said sprocket.
Claim 8
Dependent Claim
48 words
The invention according to claim 1, and said receiver means being a generally cylindrical member having a toothed rim portion mounted coaxially with the wheel; and said lug means engaging the teeth of said rim portion and extending therethrough upon movement of the shaft into the braking position.
Claim 9
Dependent Claim
64 words
The invention according to claim 1, and said mounting means being a tubular sleeve-like member, said member having a plurality of axially opening notches spaced about the periphery of one of its ends; and said retaining means including projecting pin means on said shaft, said pin means being receivable in said notches to selectively retain the shaft in the respective braking and non-braking positions.
Claim 10
Dependent Claim
40 words
The invention according to claim 1, and said mounting means including a slotted connecting portion; and said retaining means including stop means on said shaft receivable in said slotted portion to secure the shaft against rotation in the braking position.
Claim 11
Dependent Claim
55 words
The invention according to claim 7, and said slotted portion including camming means operatively associated with said stop means to rotate the shaft and move it outwardly to shift the shaft to the non-braking position upon predetermined torsional loading on the shaft incident to movement of the vehicle with the brake in the braking position.
