Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
171 words
A push button socket release mechanism for a ratchet wrench having an output drive comprising: a displaceable means in the output drive for retaining a socket on the output drive; said displaceable means being moveable along a path from a position in register with a socket disposed on said output drive whereby said socket is retained on said output drive to a position out of register with said socket whereby said socket is released from said output drive; a cam means in said output drive moveable along an axis substantially perpendicular to the path of said displaceable means for displacing said displaceable means; and said cam means having a first contacted cam portion of relatively steep slope for effecting substantial outward movement of said displaceable means in response to an increment of movement of said cam means and a second contacted cam portion of relatively shallow slope for effecting appreciable but relatively less outward movement of said displaceable means in response to a like increment of movement of said cam means.
Claim 2
Dependent Claim
171 words
A push button socket release mechanism for a ratchet wrench having an output drive comprising: a displaceable means in the output drive for retaining a socket on the output drive; said displaceable means being moveable along a path from a position in register with a socket disposed on said output drive whereby said socket is retained on said output drive to a position out of register with said socket whereby said socket is released from said output drive; a cam means in said output drive moveable along an axis substantially perpendicular to the path of said displaceable means for displacing said displaceable means; and said cam means having a first contacted cam portion of relatively steep slope for effecting substantial outward movement of said displaceable means in response to an increment of movement of said cam means and a second contacted cam portion of relatively shallow slope for effecting appreciable but relatively less outward movement of said displaceable means in response to a like increment of movement of said cam means.
Claim 3
Dependent Claim
34 words
The push button socket release mechanism of claim 1 wherein: said displaceable means is displaced transversely outward from said output drive in response to axial displacement of said cam means within said output drive.
Claim 4
Dependent Claim
17 words
The push button socket release mechanism of claim 2 wherein: said displaceable means is a lock ball.
Claim 5
Dependent Claim
30 words
The push button socket release mechanism of claim 3 wherein: said cam means is formed on a stem which is axially displaceable within said drive means by a push button.
Claim 6
Dependent Claim
45 words
The push button socket release mechanism of claim 1 wherein: said cam means includes a cam surface having a first portion of the surface providing a steep non-locking cam and a second portion of the surface providing a positive but less steep self locking cam.
