Locking means for sliding closures

A bridge type lock for double hung window and sliding door assemblies comprising an assembly having at least one member that is slidably movable relative to another, each of said relatively movable members having a surface facing in the same direction with an opening formed therein, and a one-piece lock member having a Z-shaped cross-section and having a central portion with oppositely extending substantially parallel end flange portions, means extending in spaced parallel relation from corresponding sides of the respective end flange portions, said means being positioned to simultaneously cooperate with the openings in the respective relatively movable members in selected positions thereof.

Means for locking two relatively movable members to prevent relative movement therebetween comprising two relatively movable members, means mounting at least one of said relatively movable members for sliding movement relative to the other, each of said relatively movable members having a surface thereon, the surfaces being in spaced parallel relationship to each other, a hole in each of said members extending from said parallel surfaces, and a one-piece member having substantially parallel means thereon simultaneously engageable with the holes in the relatively movable members, said one-piece member having a portion that extends between the spaced parallel surfaces and connects the substantially parallel means thereon.

Means to prevent relative movement between members comprising a pair of members having adjacent surfaces at least one of which is movable relative to the other while maintaining the adjacent surfaces in parallel relationship, an opening in each of said movable members, said openings being substantially parallel to each other, and a one-piece bridge member having spaced connected portions, one of said portions having means for cooperating with the opening in one of said movable members and the other of said portions having means thereon for simultaneously cooperating with the opening in the other of said movable members, the simultaneous cooperation of the means on the bridge member with the respective openings preventing relative movement between the relatively movable members.

Means to prevent relative movement between two members each having adjacent parallel surfaces and side edges, one of which members is movable relative to the other in a direction substantially parallel to said parallel surfaces, an opening formed in one of the parallel surfaces of one of said members, the improvement comprising a one-piece locking member having a first portion cooperatively engageable with the opening in said one member and a second portion simultaneously engageable with the side edge of the other member.

Means for preventing relative movement between members mounted for relative sliding movement, each of said members having a surface with an opening formed therein, said means comprising a locking member having spaced means thereon for simultaneously cooperating with the openings formed in the relatively movable members whereby the members are locked in selected relative positions, and means for attaching the locking member to one of said relatively movable members, said means for attaching the locking member including spring biased means.

Means to prevent relative movement between members comprising a pair of members having adjacent surfaces at least one of which is movable relative to the other while maintaining the adjacent surfaces in parallel relationship, an opening in each of said movable members, said openings being substantially parallel to each other, means including a bridge member having spaced connected portions, one of said portions having means for cooperating with the opening in one of said movable members and the other of said portions having means thereon for simultaneously cooperating with the opening in the other of said movable members, the simultaneous cooperation of the means on the bridge member with the respective openings preventing relative movement between the movable members, a second opening formed in one of said relatively movable members adjacent to the bridge member, said second opening being angularly related to the aforesaid openings, and means including spring means movable into cooperative engagement with said second opening when the bridge member is installed.
