Abstract
Abstract A lock for sliding doors utilizes an elongated locking bar and means for mounting the bar in a first closed position wherein the bar acts to lock the closure by preventing sliding thereof, and in a second open position wherein the bar member allows sliding of the door. Preferably, the mounting means includes a springlock hinge assembly, which acts to bias the bar in its first closed position, and supports it in its second open position without additional support means.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
160 words
A locking means for preventing opening of a sliding closure wherein the sliding closure is slidably mounted in a frame having a header above the sliding closure and two jambs, said header having at least one sliding channel on the header along which the closure slides, said locking means comprising: an elongated rigid bar member; and mounting means for suspending said bar member from said header in a first closed position in abutting engagement between the edge of said closure and an adjacent jamb, said mounting means including a spring lock-hinge assembly for permitting swinging movement of said bar member from said first closed position to a second open position in disengagement from between the edge of said closure and said adjacent jamb to allow sliding of said closure in said frame and biasing said locking bar into said first closed position when therein and supporting said bar member over the closure when in said second position without additional support.
Claim 2
Dependent Claim
160 words
A locking means for preventing opening of a sliding closure wherein the sliding closure is slidably mounted in a frame having a header above the sliding closure and two jambs, said header having at least one sliding channel on the header along which the closure slides, said locking means comprising: an elongated rigid bar member; and mounting means for suspending said bar member from said header in a first closed position in abutting engagement between the edge of said closure and an adjacent jamb, said mounting means including a spring lock-hinge assembly for permitting swinging movement of said bar member from said first closed position to a second open position in disengagement from between the edge of said closure and said adjacent jamb to allow sliding of said closure in said frame and biasing said locking bar into said first closed position when therein and supporting said bar member over the closure when in said second position without additional support.
Claim 3
Dependent Claim
172 words
In combination with a sliding closure with a frame having jambs at both sides thereof, a header above the sliding closure and at least one sliding channel on the header along which the closure slides, said closure being capable of sliding along said channel until one of its edges engages an adjacent jamb, a locking means for said closure comprising: an elongated rigid bar means; and mounting means for suspending said bar member from said header in a first closed position in abutting engagement between one edge of said closure and an adjacent jamb, said mounting means including a spring-lock assembly for permitting swinging movement of said bar member from said first closed position to a second open position in disengagement from between said one edge of said closure and said adjacent jamb to allow sliding of said closure in said channel, said assembly biasing said locking bar into said first closed position when therein and supporting said bar member over the closure when in said second open position without additional support.
Claim 4
Dependent Claim
172 words
In combination with a sliding closure with a frame having jambs at both sides thereof, a header above the sliding closure and at least one sliding channel on the header along which the closure slides, said closure being capable of sliding along said channel until one of its edges engages an adjacent jamb, a locking means for said closure comprising: an elongated rigid bar means; and mounting means for suspending said bar member from said header in a first closed position in abutting engagement between one edge of said closure and an adjacent jamb, said mounting means including a spring-lock assembly for permitting swinging movement of said bar member from said first closed position to a second open position in disengagement from between said one edge of said closure and said adjacent jamb to allow sliding of said closure in said channel, said assembly biasing said locking bar into said first closed position when therein and supporting said bar member over the closure when in said second open position without additional support.
Claim 5
Dependent Claim
86 words
A locking means as recited in claim 1 wherein said spring-lock assembly comprises: an upper anchoring surface rigidly attached to said header and having a flange, a lower anchoring surface rigidly attached to said elongated rigid bar member, hingedly attached to said upper anchoring surface, and having a slotted opening, and a C-shaped resilient clip having a flange at each end, one flange cooperating with the flange of the upper anchoring surface and the other flange cooperating with the slotted opening of the lower anchoring surface.
Claim 6
Dependent Claim
