Claim 1
Independent Claim
144 words
In a bunk bed having vertically-extending end post members and a horizontal guard rail member releasably connected to said post members, a pair of horizontally spaced apart releasable locks connecting said guard rail member to said post members, each lock comprising a female part on one of said members and a male part on the other, said male part comprising a relatively elongated, generally planar plate having a plurality of longitudinally aligned, spaced notches therein each defining tongue-engaging edges whereby said tongue is positionable at a plurality of locations on said female part to adjust the relationship of said members, said female part being equipped with means for mounting said female part on one of said members to space said tongue engaging edges from said one member to accommodate introduction of said tongue between said one member and one of said tongue engaging edges.
