Claim 15

A light-weight, portable foldable bed adapteD to be assembled from standard structural parts, characterized by a substantially rectangular detachable frame structure consisting of longitudinal and transverse sectional frame members of substantially identical cross sectional profile interconnected at the four corners by identical plate structures to form two frame sections, each including one transverse frame member and two longitudinal frame members, and adapted to pivot relative to each other, pivotal connecting means connecting the two frame sections of the frame structure at the free ends of the longitudinal members to enable pivotal movement about an axis parallel to a transverse frame member, the standard structural parts of the frame being provided with regularly spaced apertures along the longitudinal and transverse frame members, unitary fabric means forming a bed surface which is provided with spaced apertures along the edges thereof, and spring means engaging in mutually opposite apertures of the structural parts and of the fabric means for tautly suspending the bed surface on the longitudinal and transverse frame members of said frame part so that the entire weight of a human person directly resting on said fabric means is supported at said structural parts by way of said spring means, reinforcing frame means extending substantially in the direction of the pivot axis across a respective frame section near the area of the pivotal connection thereof to prevent buckling of the frame structure within that area under the spring forces, and the structural parts of the frame being detachable connected to each other.

Claim 16

A light-weight, portable foldable bed adapted to be assembled from standard structural parts, characterized by a substantially rectangular detachable frame structure consisting of longitudinal and transverse sectional frame members of substantially identical cross sectional profile interconnected at the four corners by identical plate structures to form two frame sections, each including one transverse frame member and two longitudinal frame members, and adapted to pivot relative to each other, pivotal connecting means connecting the two frame sections of the frame structure at the free ends of the longitudinal members to enable pivotal movement about an axis parallel to a transverse frame member, the standard structural parts of the frame being provided with regularly spaced apertures along the longitudinal and transverse frame members, unitary fabric means forming a bed surface which is provided with spaced apertures along the edges thereof, and spring means engaging in mutually opposite apertures of the structural parts and of the fabric means for tautly suspending the bed surface on the longitudinal and transverse frame members of said frame part so that the entire weight of a human person directly resting on said fabric means is supported at said structural parts by way of said spring means, the standard structural parts of the frame being detachably connected to each other by two-partite connecting means each essentially consisting of a plug member with a head portion and an annular groove in its shank portion and a locking member having an apertured base body portion adapted to engage in said groove and a bent-back part adapted to engage frictionally with the head portion.
