Abstract
Abstract A lock set handle for use with a lock set spindle rotatable about an axis has a handle body with a cavity adapted to receive the spindle and has driving means engageable with the spindle. Disposed eccentrically of the axis are means interengaging the driving means and the handle body for preventing relative rotation of the driving means and the handle body with respect to the axis. For a reversible handle, the interengaging means interlocks in either of two diametrically opposite positions.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
165 words
A lock set handle, for use with a lock set having a spindle rotatable about an axis and having an open-end slot in said spindle, comprising a handle body elongated transversely of said axis and having a circular central cavity centered on said axis and a pair of said cavities open thereto, said side cavities being disposed on the opposite sides of said axis and aligned in the direction of elongation of said handle body, a driving member at least partly in said central cavity and surrounding said spindle for rotation about said axis, a tang on said driving member slidable in said slot, a pair of means on said handle body each at least partly in one of said side cavities and engageable with said driving member for preventing rotary movement of said driving member relative to said handle body, and means on said body and engageable with said driving member for preventing axial motion of said driving member relative to said handle body.
Claim 2
Dependent Claim
165 words
A lock set handle, for use with a lock set having a spindle rotatable about an axis and having an open-end slot in said spindle, comprising a handle body elongated transversely of said axis and having a circular central cavity centered on said axis and a pair of said cavities open thereto, said side cavities being disposed on the opposite sides of said axis and aligned in the direction of elongation of said handle body, a driving member at least partly in said central cavity and surrounding said spindle for rotation about said axis, a tang on said driving member slidable in said slot, a pair of means on said handle body each at least partly in one of said side cavities and engageable with said driving member for preventing rotary movement of said driving member relative to said handle body, and means on said body and engageable with said driving member for preventing axial motion of said driving member relative to said handle body.
Claim 3
Dependent Claim
49 words
A lock set handle as in claim 1 in which said driving member is engageable with said spindle in but one position of rotation about said axis, and said engaging means interrelates said driving member and said handle body in either of two positions of rotation about said axis.
Claim 4
Dependent Claim
74 words
A lock set handle as in claim 1 in which said driving member extends into both of said side cavities and has a longitudinal slot, and a cylinder unit having a circular cylindrical unit body and an axially extending radial projection thereon is disposed with said unit body in said driving member and said radial projection disposed in said spindle slot and in said driving member slot and in either one of said cavities.
Claim 5
Dependent Claim
113 words
A lock set handle, for use on a spindle rotatable about a central axis, said spindle having first walls dEfining a keyway slot and being adapted to receive a detent, comprising a driving sleeve, a tang on said driving sleeve extending into said slot and engageable with said first walls, means including second walls forming an opening in said driving sleeve adapted to receive said detent, means including a third wall in said driving sleeve defining a notch eccentric with respect to said axis, a handle having an opening therein adapted to receive said driving sleeve, and blocking means engaging said handle eccentrically with respect to said axis and extending into said notch.
Claim 6
Dependent Claim
113 words
A lock set handle, for use on a spindle rotatable about a central axis, said spindle having first walls dEfining a keyway slot and being adapted to receive a detent, comprising a driving sleeve, a tang on said driving sleeve extending into said slot and engageable with said first walls, means including second walls forming an opening in said driving sleeve adapted to receive said detent, means including a third wall in said driving sleeve defining a notch eccentric with respect to said axis, a handle having an opening therein adapted to receive said driving sleeve, and blocking means engaging said handle eccentrically with respect to said axis and extending into said notch.
Claim 7
Dependent Claim
32 words
A device as in claim 4 in which said handle has a recess eccentric with respect to said axis, and a lug plate disposed in said recess and engaging said blocking means.
