Abstract

Abstract The invention relates to a lock for use with a pair of overlapping doors or windows which are slidably mounted in a pair of adjacent upper tracks, wherein one of the tracks includes a vertical side rail. The lock includes a faceplate and at least one bolt member secured to the faceplate and adapted to slidably pass through the frame of one of the closure members into engagement with the frame of the other. An eccentric-type lock device mounted on the faceplate is adapted to engage one of the closure members for the purpose of securing the faceplate thereto. The upper edge of the faceplate is adapted to abut the side rail of the upper track when it is locked to the inside closure member and thereby limit the vertical movement of the two closures in the upper tracks and/or secure the two doors rigidly together to prevent lateral shifting relative to each other.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 196 words
A lock for use with a pair of overlapping closure members at least one of which is slideably mounted in an upper track including a side rail, said lock comprising: a. faceplate means, b. first bolt means secured to said faceplate means for passing through one of the closure members and at least partially through the other closure members to thereby prevent the closure members from sliding relative to each other, c. lock means associated with said faceplace means for securing said faceplate means to one of the closure members and retaining said bolt means within the closure members, and d. release means associated with said faceplate means for urging said faceplate means away from the closure to which it is adapted to be locked and said bolt means out of engagement with one of the closure members to thereby permit the closure members to slide relative to each other, e. said release means including pin means slideably passing through said faceplate means and being adapted to be secured to the closure member to which said faceplate means is adapted to be locked, f. said release means further including spring means positioned around said pin means.
Claim 2
Dependent Claim 196 words
A lock for use with a pair of overlapping closure members at least one of which is slideably mounted in an upper track including a side rail, said lock comprising: a. faceplate means, b. first bolt means secured to said faceplate means for passing through one of the closure members and at least partially through the other closure members to thereby prevent the closure members from sliding relative to each other, c. lock means associated with said faceplace means for securing said faceplate means to one of the closure members and retaining said bolt means within the closure members, and d. release means associated with said faceplate means for urging said faceplate means away from the closure to which it is adapted to be locked and said bolt means out of engagement with one of the closure members to thereby permit the closure members to slide relative to each other, e. said release means including pin means slideably passing through said faceplate means and being adapted to be secured to the closure member to which said faceplate means is adapted to be locked, f. said release means further including spring means positioned around said pin means.
Claim 3
Dependent Claim 132 words
In combination with a pair of relatively sliding overlapping closure members mounted in upper and lower tracks, a lock comprising: a. faceplate means, b. first bolt means being secured to said faceplate means and slideably passing through one of said closure members into an overlapping portion of the other of said closure members, c. lock means for releaseably securing said faceplate means to one of said closure members, and d. second bolt means secured to said faceplate means and passing through one of said closure members into an overlapping portion of the other of said closure members, e. one of said upper tracks including a side rail, f. a portion of said faceplate means abutting said side rail to thereby limit the vertical movement of said closure members in said upper tracks.
Claim 4
Dependent Claim 132 words
In combination with a pair of relatively sliding overlapping closure members mounted in upper and lower tracks, a lock comprising: a. faceplate means, b. first bolt means being secured to said faceplate means and slideably passing through one of said closure members into an overlapping portion of the other of said closure members, c. lock means for releaseably securing said faceplate means to one of said closure members, and d. second bolt means secured to said faceplate means and passing through one of said closure members into an overlapping portion of the other of said closure members, e. one of said upper tracks including a side rail, f. a portion of said faceplate means abutting said side rail to thereby limit the vertical movement of said closure members in said upper tracks.
Claim 5
Dependent Claim 143 words
In combination with a pair of relatively sliding overlapping closure members mounted in upper and lower tracks, a lock comprising: a. faceplate means, b. first bolt means being secured to said faceplate means and slideably passing through one of said closure members into an overlapping portion of the other of said closure members, c. lock means for releaseably securing said faceplate means to one of said closure members, and d. release means for resiliently urging said faceplate means away from said closure members a distance sufficient to withdraw said bolt means from said the other of said closure members, e. said release means including pin means slideably passing through the aperture in said faceplate means and secured to one of said closure members, f. said release means further including spring means positioned between said faceplate means and said one of said closure members.
Claim 6
Dependent Claim 143 words
In combination with a pair of relatively sliding overlapping closure members mounted in upper and lower tracks, a lock comprising: a. faceplate means, b. first bolt means being secured to said faceplate means and slideably passing through one of said closure members into an overlapping portion of the other of said closure members, c. lock means for releaseably securing said faceplate means to one of said closure members, and d. release means for resiliently urging said faceplate means away from said closure members a distance sufficient to withdraw said bolt means from said the other of said closure members, e. said release means including pin means slideably passing through the aperture in said faceplate means and secured to one of said closure members, f. said release means further including spring means positioned between said faceplate means and said one of said closure members.
