Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
144 words
A latch unit for a pair of rectangular telescoped rails having a pair of adjacent side walls with aligned openings therein, said unit comprising a hollow rectangular body of one-piece, non-rigid construction telescoped over said telescoped rails, a locking projection integrally formed with said body on one side thereof and shaped to fit in said pair of said aligned openings in said rails so as to latch said rails in predetermined relative positions, said one side of said body being of a deformable shape enabling movement of said projection in a direction axially of said aligned openings between a position extending into said openings and a position withdrawn from said openings, and handle means on said one side of said body positioned in substantial alignment with said locking projection so as to be manually operable to withdraw said locking projection from said aligned openings.
Claim 2
Dependent Claim
144 words
A latch unit for a pair of rectangular telescoped rails having a pair of adjacent side walls with aligned openings therein, said unit comprising a hollow rectangular body of one-piece, non-rigid construction telescoped over said telescoped rails, a locking projection integrally formed with said body on one side thereof and shaped to fit in said pair of said aligned openings in said rails so as to latch said rails in predetermined relative positions, said one side of said body being of a deformable shape enabling movement of said projection in a direction axially of said aligned openings between a position extending into said openings and a position withdrawn from said openings, and handle means on said one side of said body positioned in substantial alignment with said locking projection so as to be manually operable to withdraw said locking projection from said aligned openings.
Claim 3
Dependent Claim
81 words
A latch unit according to claim 1 wherein said hollow rectangular body is dimensioned on the side opposite said one side and on the remaining two sides thereof to fit snugly on said rails, said one side being of a length in a direction circumferentially of said body greater than the length of said opposite side, said one side also being of irregular non-linear shape enabling the deformation thereof to accommodate movement of said projection into and out of said openings.
Claim 4
Dependent Claim
24 words
A latch unit according to claim 2 wherein said one side has angularly related sections thereby extending the effective length of said one side.
