Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
167 words
A controlling handle for the frame of a lawnmower or other carriage which is movable between a locked erected condition and a collapsed condition, said handle comprising means for pivoting an end portion on the frame to provide for movement of the handle between said conditions, a locking member on the frame pivoted for movement between locking and unlocking positions, an abutment carried on the handle end portion and a capturing element therefor carried by the locking member and having a ramp surface for engagement with said abutment, annular stop means surrounding the locking member pivot for arresting rotation of the handle about its pivoting means beyond its erected condition, and means for biasing the locking member towards its locking position whereby in the erected condition of the handle the ramp surface of the capturing element applies a force to the abutment tending to draw the handle onto the annular stop means to maintain the handle erected until the locking member is pivoted towards its unlocking position.
Claim 2
Dependent Claim
167 words
A controlling handle for the frame of a lawnmower or other carriage which is movable between a locked erected condition and a collapsed condition, said handle comprising means for pivoting an end portion on the frame to provide for movement of the handle between said conditions, a locking member on the frame pivoted for movement between locking and unlocking positions, an abutment carried on the handle end portion and a capturing element therefor carried by the locking member and having a ramp surface for engagement with said abutment, annular stop means surrounding the locking member pivot for arresting rotation of the handle about its pivoting means beyond its erected condition, and means for biasing the locking member towards its locking position whereby in the erected condition of the handle the ramp surface of the capturing element applies a force to the abutment tending to draw the handle onto the annular stop means to maintain the handle erected until the locking member is pivoted towards its unlocking position.
Claim 3
Dependent Claim
23 words
A controlling handle according to claim 1, wherein the stop means is a metal bush providing a socket for the locking member pivot.
Claim 4
Dependent Claim
61 words
A controlling handle according to claim 1 wherein the handle has two articulated sections retainable in selected relative angular positions, the handle sections at their corresponding adjacent ends having flattened portions pivoted on a tie rod extending transversely across the handle, and a cam-type pivoted clamp on an end of the tie rod and rotatable for clamping the flattened portions together.
Claim 5
Dependent Claim
87 words
A controlling handle according to claim 1, wherein the abutment is a pin, the locking member is a plate, said capturing element is a groove to accept the pin, and the biasing means is a spring urging the plate towards the pin when the handle is engaged with the stop means in its erected condition, said groove having an inclined wall which by contact with the pin jams the end portion of the handle against said stop means to provide rigidity of erection and compensation for wear.
Claim 6
Dependent Claim
191 words
A controlling handle for a rotary lawnmower baseplate articulated for folding from an erected condition to a collapsed condition overlying the baseplate, said handle comprising an intermediate elbow joint for folding of an upper part of the handle about a lower part, means for locking said two parts in an erected condition, lower end portions on said lower part having locking projections and being pivoted at opposite sides of the baseplate, for movement between said erected and collapsed conditions of the handle and at each of said sides a latching plate on a pivot Supported by the baseplate, spring means urging the latching plate to a latching position, a slot in the latching plate to capture for latching in the erected condition of the handle the locking projection on the respective handle end portion, an annular stop element surrounding the latching plate pivot and arresting rotation of the handle lower end portion beyond said erected condition of the handle, and catch means operative between the latching plate and said lower end portion to hold the latching plate in a displaced condition off its latching position until the handle is partly collapsed.
Claim 7
Dependent Claim
191 words
A controlling handle for a rotary lawnmower baseplate articulated for folding from an erected condition to a collapsed condition overlying the baseplate, said handle comprising an intermediate elbow joint for folding of an upper part of the handle about a lower part, means for locking said two parts in an erected condition, lower end portions on said lower part having locking projections and being pivoted at opposite sides of the baseplate, for movement between said erected and collapsed conditions of the handle and at each of said sides a latching plate on a pivot Supported by the baseplate, spring means urging the latching plate to a latching position, a slot in the latching plate to capture for latching in the erected condition of the handle the locking projection on the respective handle end portion, an annular stop element surrounding the latching plate pivot and arresting rotation of the handle lower end portion beyond said erected condition of the handle, and catch means operative between the latching plate and said lower end portion to hold the latching plate in a displaced condition off its latching position until the handle is partly collapsed.
Claim 8
Dependent Claim
54 words
A controlling handle according to claim 5, wherein the catch means is a post on the handle lower end portion having at least one tapering wall, and a spring catch on the latching plate to flex in passing over the tapering wall and then to lock behind the post in the handle''s erected condition.
