Abstract
Abstract A plastic baby crib construction having two crib-sides connected to two crib-ends is made of cross-members and upright members having a uniform lateral cross-section. The structural members are hollow, substantially rectangular extrusions having opposing side walls and end walls, four smoothly rounded corners and two partitions extend longitudinally of and are spaced within said hollow extrusion to define three longitudinal channels within said extrusion. A T-shaped member is used to connect the cribsides to the crib-ends to permit them to slide vertically, the head of the T-shaped member sliding within one of the channels. With this type of construction, no hardware or sharp edges are exposed and the crib may be easily assembled.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
170 words
In an improved baby-crib construction comprising two cribsides and two crib-ends, at least one of said crib-sides being movable in a vertical direction relative to said crib-ends; each crib-end having two parallel spaced-apart uprights and two parallel spaced-apart cross-members disposed horizontally between and secured to said uprights; each crib-side having two parallel spaced-apart cross-members, each end of said crib-side crossmember being adjacent a respective upright of a crib-end; and means being provided for engaging each end of the cross-members of at least one of said crib-sides with the respective uprights of said crib-ends which is adapted to permit said crib-side to move relative to said crib-ends; the improvement comprising each said uprights and said cross-members of said crib-ends and cribsides having a uniform lateral cross-section and consisting of a hollow, substantially rectangular extrusion having opposing side and end walls and four smoothly rounded corners and at least one partition extending longitudinally of and being spaced within said hollow extrusion to define a plurality of longitudinally extending channels within said extrusion.
Claim 2
Dependent Claim
170 words
In an improved baby-crib construction comprising two cribsides and two crib-ends, at least one of said crib-sides being movable in a vertical direction relative to said crib-ends; each crib-end having two parallel spaced-apart uprights and two parallel spaced-apart cross-members disposed horizontally between and secured to said uprights; each crib-side having two parallel spaced-apart cross-members, each end of said crib-side crossmember being adjacent a respective upright of a crib-end; and means being provided for engaging each end of the cross-members of at least one of said crib-sides with the respective uprights of said crib-ends which is adapted to permit said crib-side to move relative to said crib-ends; the improvement comprising each said uprights and said cross-members of said crib-ends and cribsides having a uniform lateral cross-section and consisting of a hollow, substantially rectangular extrusion having opposing side and end walls and four smoothly rounded corners and at least one partition extending longitudinally of and being spaced within said hollow extrusion to define a plurality of longitudinally extending channels within said extrusion.
Claim 3
Dependent Claim
173 words
In a baby-crib of claim 1, said extrusion having first and second partitions, said first partition spanning said opposing side walls and said second partition being disposed proximate an end-wall of said extrusion to define an elongate channel; where the end wall adjacent the second partition of diametrically opposed uprights of said crib-ends is provided with a longitudinal slot along at least a portion of the length of said end wall; said means for engaging each end of the crib-side cross-members with the respective upright comprising a T-shaped member provided at each end of the cross-members of the respective crib-side, the head portion of said T-shaped member Being adapted to slide vertically within said elongate channel, the shank of said T-shaped member being adapted to extend outwardly through said slot and secured to the end of the respective cross-member of said crib-side; said T-shaped member engaging each end of the crib-side cross-members with the respective diametrically opposed uprights of said crib-ends thereby to permit vertical movement of said crib-side relative to said crib-ends.
Claim 4
Dependent Claim
90 words
In a baby-crib of claim 2, said head and shank of said T-shaped member being an integral molded piece of plastic, the width of said head being substantially greater than the width of said slot and less than the distance between the opposing side walls of said extrusion; said head being adapted to slide freely within said elongate channel; the width of said shank being less than the width of said slot where said shank is positioned on said head to be in register with said slot and extend therethrough.
Claim 5
Dependent Claim
113 words
In a baby-crib of claim 1, a plurality of parallel bars being vertically spaced between said cross-members of each crib-side; each of said bars being substantially uniform in length and diameter; a plurality of spaced-apart circular apertures being formed in an end wall and at least one of said partitions of each of said cross-members of each crib-side, the apertures in an end-wall of one cross-member being vertically aligned with the apertures in an end-wall of the other cross-member of a crib-side; said apertures being of a diameter which permits a press-fit insertion of a bar therein whereby said plurality of bars are spaced between and secured to the cross-members of a crib-side.
Claim 6
Dependent Claim
182 words
In a baby-crib of claim 4, said partitions in said extrusion being first and second substantially parallel webs spanning said opposing side walls thereof, said second web being disposed adjacent and parallel to one of said end walls of said extrusion, an elongate channel being defined between said second web and said end wall; where the end wall adjacent the second web of diametrically opposed uprights of said crib-ends is provided with a longitudinal slot along at least a portion of the length of said end wall; said means comprising a T-shaped member provided at each end of the cross-members of the respective crib-sides, the head portion of said T-shaped member being adapted to slide vertically within said elongate channel, the shank of said T-shaped member being adapted to extend outwardly through said slot and being firmly connected to the end of the respective cross-member of said crib-side; said T-shaped member slidably engaging each end of the cross-member of a crib-side with the respective diametrically opposed uprights of said crib-end thereby to permit vertical movement of said crib-side relative to said crib-ends.
Claim 7
Dependent Claim
61 words
In a baby-crib of claim 5, said shank of said T-shaped member extending longitudinally into at least one of said channels of a cross-member end of a crib-side; said shank being provided with means for encircling at least in part a bar closest to said cross-member end which passes through said apertures formed in said end-wall and web of said cross-member.
Claim 8
Dependent Claim
36 words
In a baby-crib of claim 6, an end cap being provided on each cross-member end of said crib-sides; each end-cap being provided with an aperture to permit the shank of said T-shaped member to extend therethrough.
Claim 9
Dependent Claim
39 words
In a baby-crib of claim 7, said shank having flange means for securely positioning said shank in said aperture of said end-cap to preclude lateral or vertical movement of said shank relative to the respective cross-member of a crib-side.
Claim 10
Dependent Claim
123 words
A continuous lightweight extrusion of uniform lateral cross-section for use as structural members in a baby crib construction comprising a hollow substantially rectangular member having opposing side and end walls and four smoothly rounded corners, at least one partition extending longitudinally of, and being spaced within said hollow extrusion to define a plurality of longitudinally extending channelS within said extrusion; whereby said continuous extrusion is cut into lengths to provide uprights and cross-members for the crib-sides and crib-ends, said cross-members which retain bars for the crib-sides and crib-ends being provided with apertures in an end wall and at least one partition thereof, the diameter of said apertures being such that said bars are press-fitted therein to secure said bars between the respective cross-members.
Claim 11
Dependent Claim
