Abstract
Abstract A lock assembly having special utility for locking sliding doors and the like is disclosed. The lock assembly comprises a cylinder lock having a rotor case and a rotatable rotor disposed therein. The rotor has pin members configured such that upon insertion of an associated key into the rotor, the pin members retract and the rotor is rendered selectively rotatable in the rotor case. A movable runner is coupled to the rotor and a hook member is coupled to the runner such that when the runner is moved from the unlocked position to the locked position, the hook moves into a "deadlock" zone. A driver member is also connected to the runner to aid it in moving from its locked position to the unlocked position and vice versa.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
158 words
A lock assembly for sliding doors comprising: a. a cylindrical lock having a rotor case and a rotor, said rotor having pin members disposed circumferentially about said rotor and configured such that upon insertion of an associated key into said rotor, said pin members retract and said rotor is rendered selectively rotatable in said rotor case; b. a movable runner coupled to said rotor, said runner having a slot, said slot having a free-zone channel and a deadlock channel; c. a rotatable hook member coupled to said runner, said hook member having a pin member configured such that when said hook member is in the unlocked position, said pin member fits into said free-zone channel, and when said hook member is in the locked position, said pin member fits into said deadlock channel; and d. a driving means movable disposed and coupled to said hook member, whereby said hook member is rotatable by manually actuating said driving means.
Claim 2
Dependent Claim
158 words
A lock assembly for sliding doors comprising: a. a cylindrical lock having a rotor case and a rotor, said rotor having pin members disposed circumferentially about said rotor and configured such that upon insertion of an associated key into said rotor, said pin members retract and said rotor is rendered selectively rotatable in said rotor case; b. a movable runner coupled to said rotor, said runner having a slot, said slot having a free-zone channel and a deadlock channel; c. a rotatable hook member coupled to said runner, said hook member having a pin member configured such that when said hook member is in the unlocked position, said pin member fits into said free-zone channel, and when said hook member is in the locked position, said pin member fits into said deadlock channel; and d. a driving means movable disposed and coupled to said hook member, whereby said hook member is rotatable by manually actuating said driving means.
Claim 3
Dependent Claim
20 words
The lock assembly of claim 1 wherein said rotor has a cam, said cam coupling said runner to said rotor.
Claim 4
Dependent Claim
60 words
The lock assembly of claim 2 wherein said runner has a second slot, said driving means is a thumb turn bar having a pin member disposed thereon which is engaged by said second slot whereby rotation of said bar causes said pin member to shift said runner and to rotate said hook member selectively into said locked or unlocked position.
Claim 5
Dependent Claim
205 words
A lock assembly for sliding doors comprising: a cylindrical lock having a rotor case and a rotor, said rotor having pin members circumferentially disposed about said rotor and configured such that upon insertion of an associated key into said rotor, said pin members retract and said rotor is rendered selectively rotatable in said rotor case; a movable runner coupled to said rotor, said runner having a slot, said slot having a free-zone channel and a deadlock channel; a cam, said cam coupling said runner to said rotor; a rotatable hook member coupled to said runner, said hook member having a pin member configured such that when said hook member is in the unlocked position, said pin member fits into said free-zone channel, and when said hook member is in the locked position, said pin member fits into said deadlock channel; a driving means movably disposed and coupled to said hook member, whereby said hook member is rotatable by manually actuating said driving means; and a trigger member movably coupled to said lock and extending outwardly therefrom, said trigger member having a movable seat member which engages in opening of said runner to prevent said runner from moving when said door is inappropriately situated for locking.
Claim 6
Dependent Claim
205 words
A lock assembly for sliding doors comprising: a cylindrical lock having a rotor case and a rotor, said rotor having pin members circumferentially disposed about said rotor and configured such that upon insertion of an associated key into said rotor, said pin members retract and said rotor is rendered selectively rotatable in said rotor case; a movable runner coupled to said rotor, said runner having a slot, said slot having a free-zone channel and a deadlock channel; a cam, said cam coupling said runner to said rotor; a rotatable hook member coupled to said runner, said hook member having a pin member configured such that when said hook member is in the unlocked position, said pin member fits into said free-zone channel, and when said hook member is in the locked position, said pin member fits into said deadlock channel; a driving means movably disposed and coupled to said hook member, whereby said hook member is rotatable by manually actuating said driving means; and a trigger member movably coupled to said lock and extending outwardly therefrom, said trigger member having a movable seat member which engages in opening of said runner to prevent said runner from moving when said door is inappropriately situated for locking.
Claim 7
Dependent Claim
210 words
A lock assembly for sliding doors comprising: a cylindrical lock having a rotor case and a rotor, said rotor having pin members circumferentially disposed about said rotor and configured such that upon insertion of an associated key into said rotor, said pin members retract and said rotor is rendered selectively rotatable in said rotor case; a movable runner coupled to said rotor, said runner having a slot, said slot having a free-zone channel and a deadlock channel; a cam, said cam coupling said runner to said rotor; a rotatable hook member coupled to said runner, said hook member having a pin member configured such that when said hook member is in the unlocked position, said pin member fits into said free-zone channel, and when said hook member is in the unlocked position, said pin member fits into said deadlock channel; and a driving means movably disposed and coupled to said hook member, said driving means comprising a locking bar interposed between said runner and said hook member, and a slide catch coupled to said runner, whereby said hook member is rotatable by manually sliding the runner with said slide catch causing said locking bar to transform the vertical movement of said runner into the rotating movement of said hook member.
Claim 8
Dependent Claim
