Non-handed window lock actuator

A non-handed actuator for window locks of the type in which a lock control member is moved by said actuator to control the locking of a window sash to a window frame, said actuator comprising:

• a base securable to the window frame;
• a handle secured to said base for pivoting about a first axis through an angle of approximately X degrees, said handle generally extending in a first radial direction from said first axis;
• a drive link secured for pivoting with said handle, said drive link generally extending in a second radial direction from said first axis, said first and second radial directions being on generally opposite sides of said first axis;
• a connecting link securable to the lock control member of a window lock and pivotable relative to said drive link, said connecting link having a spacing member and a connecting member, said connecting member being securable to the lock control member and pivotable relative to said spacing member between limit positions approximately 180 degrees apart;
• and
• a first tab on one of said spacing member and connecting member and a second tab on one of said spacing member and connecting member, said first tab abutting one side of the other of said spacing member and said connecting member when said connecting member is at one of said limit positions and said second tab abutting the other side of the other of said spacing member and connecting member when said connecting member is at the other of said limit positions.

• a connecting link securable to the lock control member of a window lock and pivotable relative to said drink link, said connecting link not being directly connected to said base and having stops limiting the relative pivoting of the connecting link relative to the drive link so as to be independent of said base, said relative pivoting being limited to an angle of approximately 2X degrees.

• a connecting link securable to the lock control member of a window lock and pivotable relative to said drink link, said connecting link comprising first and second connecting link members, said first connecting link member being pivotally connected to said drive link and said second connecting link member being pivotally connected to said first connecting link member;
• and
• stops limiting the relative pivoting of the connecting link relative to the drive link to an angle of approximately 2X degrees, said stops comprising tabs on opposite sides of said first connecting link member limiting pivoting of the drive link relative to the first connecting link member and of the first connecting link member relative to the second connecting link member, at least one tab abutting the drive link at each limit of relative pivoting of the drive link to the first connecting link member and at least one tab abutting the second connecting link member at each limit of relative pivoting of the first connecting link member to the second connecting link member.
