Abstract
Abstract The assembly and disassembly of such a bed is provided by a resilient clamping of the tips 7 of the side panels B and D on the posts 4 of the head and foot panels A and C, while said side panels and said head and foot panels form a dihedral greater than 90°. The side panels are adjustable in height by means of a sliding movement of the tips 7 along the posts 4. The insertion of the mattress support S forbids any accidental disassembly of the bed.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
231 words
A dismountable bed, in particular for children, comprising: an upright head panel at one end; an upright foot panel at the other end; two side panels interconnecting opposite sides of said head and foot panels; each of said head and foot panels comprising two vertical posts and a cross-piece disposed between said posts, the side edges of said cross-piece being, at least at some location therealong, spaced from said posts defining an interval therebetween, each of said side panels including at each of their lateral ends at least two tips adapted to engage said vertical posts, each of said tips comprising means for preventing disengagement of said side panel tips with said posts when the angle of the dihedral formed by the planes of said side panel and the adjacent head or foot panel is substantially equal to 90°, and for allowing disengagement when the angle is substantially different from 90°, said means comprising a recess in said tip for engaging said vertical post and a lateral aperture through which said vertical post passes into said recess, said aperture facing away from said cross-piece when the bed is in the operative position in which said dihedral angle is substantially 90°; and substantially rectangular, removable mattress support means, located between said head, foot and side panels, for maintaining the bed in the operative position in which said dihedral angle is substantially 90°.

A dismountable bed, in particular for children, comprising: an upright head panel at one end; an upright foot panel at the other end; two side panels interconnecting opposite sides of said head and foot panels; each of said head and foot panels comprising two vertical posts and a cross-piece disposed between said posts, the side edges of said cross-piece being, at least at some location therealong, spaced from said posts defining an interval therebetween, each of said side panels including at each of their lateral ends at least two tips adapted to engage said vertical posts, each of said tips comprising means for preventing disengagement of said side panel tips with said posts when the angle of the dihedral formed by the planes of said side panel and the adjacent head or foot panel is substantially equal to 90°, and for allowing disengagement when the angle is substantially different from 90°, said means comprising a recess in said tip for engaging said vertical post and a lateral aperture through which said vertical post passes into said recess, said aperture facing away from said cross-piece when the bed is in the operative position in which said dihedral angle is substantially 90°; and substantially rectangular, removable mattress support means, located between said head, foot and side panels, for maintaining the bed in the operative position in which said dihedral angle is substantially 90°.
Claim 3
Dependent Claim
28 words
Bed according to claim 1, wherein said posts are substantially circular in cross-section and wherein said tips are resilient and are assembled with said posts by resilient clamping.
Claim 4
Dependent Claim
60 words
Bed according to claim 1, wherein said tips of said side panels can slide along the vertical posts of said head and foot panels, the height of each side panel being adjustable through resiliently retractable support means provided for supporting said side panels in the high position, stops being further provided to limit the sliding movement of said side panels.
Claim 5
Dependent Claim
60 words
Bed according to claim 3, wherein each resiliently retractable support means is a string wire in the form of a right-angled triangle, the small side of which supports the tip of a side panel, said small side being provided to retract in a hole in said post when the large face of the right-angled triangle is pressed against said post.
Claim 6
Dependent Claim
35 words
Bed according to claim 1, wherein said support means is adjustable in height by engagement of projections of said mattress support means in supporting elements secured on said head and foot panels at predetermined heights.
Claim 7
Dependent Claim
81 words
Bed according to claim 5, wherein said supporting elements are U-shaped elements, the ends of the arms of which are provided with lateral projections, said supporting elements being provided to be manually hooked or unhooked on the foot and head panels by resiliently deforming the supporting element, and moving the side projections of said element in or away from holes provided in the posts and in the cross-piece, the posts and the cross-piece having several vertically spaced pairs of such holes.
