Abstract
A cam lock that includes a cam body having a lobe-shaped working periphery and rotatable between a first locking position and a second unlocked position, a handle shaft mounted to the cam body for moving the cam body through a predetermined range of motion, and a cam shaft mounted to the cam body for pivotal movement relative to the cam body and having an end remote from the cam body for being fixed to a structure to be locked by a force applied against the structure. A bushing is mounted on the cam shaft and has an end proximate the cam body against which a locking force is applied when the cam body is rotated into its locking position.
Claims10
A cam lock, comprising:
- (a) a cam body having a lobe-shaped working periphery and rotatable between a first locking position and a second unlocked position;
- (b) a handle shaft mounted to the cam body for moving the cam body through a predetermined range of motion;
- (c) a cam shaft mounted to the cam body for pivotal movement relative to the cam body and having an end remote from the cam body for being fixed to a structure to be locked by a force applied against the structure;
- and
- (d) a bushing mounted on the cam shaft and having an end proximate the cam body against which a locking force is applied when the cam body is rotated into its locking position, wherein:
- the cam lock includes a slot formed in the cam body, a perpendicular bore formed through the cam body in a position to intersect the slot, the cam shaft positioned in the slot and fixed into a rotatable position by a dowel pin that extends through the bore in the cam body.
A cam lock for locking an elongate member in a predetermined desired position along a length of the elongate member, comprising:
- (a) a cam body having a lobe-shaped working periphery and rotatable between a first locking position and a second unlocked position;
- (b) a handle shaft mounted to the cam body for moving the cam body through a predetermined range of motion;
- (c) a cam shaft mounted to the cam body for pivotal movement relative to the cam body and having an end remote from the cam body operatively associated with a collar in which the elongate member is positioned for movement therein along the longitudinal axis of the elongate member;
- (d) a bushing mounted on the cam shaft and having an end proximate the cam body against which a locking force is applied when the cam body is rotated into its locking position;
- and
- (e) the bushing having an end distal from the cam body and adapted to exert a locking force against the collar when the cam body is in its locking position to fix the elongate member in the desired position, wherein:
- the cam lock includes a slot formed in the cam body, a perpendicular bore formed through the cam body in a position to intersect the slot, a cam shaft positioned in the slot and fixed into a rotatable position by a dowel pin that extends through the bore in the cam body.
A trolling motor assembly, comprising:
- (a) a motor positioned in a motor housing;
- (b) a propeller drive shaft interconnecting the motor and a propeller;
- (c) a locking block having a through bore within which the propeller drive shaft is mounted for vertical movement of the propeller to a predetermined desired water depth;
- and
- (d) a cam lock for locking the propeller drive shaft in the predetermined desired position;
- and comprising:
- (I) a cam body having a lobe-shaped working periphery rotatable between a first locking position and a second unlocked position;
- (ii) a handle shaft mounted to the cam body for moving the cam body through a predetermined range of motion;
- (iii) a cam shaft mounted to the cam body for pivotal movement relative to the cam body and having an end remote from the cam body operatively associated with a collar in which the propeller drive shaft is positioned for movement therein along the longitudinal axis of the propeller drive shaft:
- (iv) a bushing mounted on the cam shaft and having an end proximate the cam body against which a locking force is applied when the cam body is rotated into its locking position;
- and
- (v) the bushing having an end distal from the cam body and adapted to exert a locking force against the collar when the cam body is in its locking position to fix the propeller drive shaft in the desired position.
