Bedstead

Claim 2

A bedstead comprising: A. an undercarriage; B. a bedframe; C. flexible means constituting a bedframe support operatively associated with and interconnecting said bedframe and said undercarriage; D. draw means for so effectively shortening and lengthening said flexible means as to vertically move said bedframe with respect to said undercarriage; E. elevated position locking means for at least one end of said bedframe, said draw means being reversible and operable to raise or lower the bedframe end remote from the locked end thereof for obliquely positioning said bedframe; and F. frictional brake blocks, said flexible means constituting strands passing through said brake blocks, said strands being in sets respectively operatively connected to opposite ends of said bedframe, said brake blocks preventing slack in one said set of strands when the other set of said strands is withdrawn with the bedframe moving to an oblique position.

Claim 3

A bedstead as claimed in claim 1, including elevated position locking means at each end of said bedframe, said locking means being releasable only when both said ends are at maximum elevated position.

Claim 4

A bedstead as claimed in claim 2, said flexible means comprising first and second sets of flexible strands, bedframe support and guide means for said flexible strands attached to said bedframe at opposite ends thereof, ends of said strands being attached to said support means, said flexible strands from one said end passing around guide means therefor and extending longitudinally inwardly along said undercarriage, direction reversing guide means for said flexible strands from the other said end, said strands from the other said end passing around said reversing guide means, longitudinally toward said other end and substantially parallel to the extended strands from said one end, and means for longitudinally drawing selectively said sets of flexible strands around said support and guide means, and said reversing means, to elevate or lower said bedframe supported thereby through shortening or lengthening the effective bedframe support portions of said flexible strands.

Claim 5

A bedstead comprising: A. a rigid rectangular undercarriage; B. a bedframe; C. upstanding posts at the corners of said undercarriage constituting first and second end post sets; D. first flexible means connected respectively to each said post of said first post set; E. second flexible means connected respectively to each said post of said second post set; F. first bedframe support and guide means for said first flexible means attached to said bedframe proximate one end thereof, said first flexible means extending around said first guide means and longitudinally inwardly along said undercarriage; G. second bedframe support and guide means for said second flexible means attached to said bedframe proximate the other end thereof; H. second flexible means reversing means on said bedframe positioned inwardly from said other end, said second flexible means extending around said second guide means, inwardly along said undercarriage, around said reversing means and longitudinally toward said other end substantially parallel to the longitudinally extended portion of said first flexible means; I. a longitudinally movable draw bar mounted transversely of said bedframe; J. the free ends of said first and second flexible means being attached to said draw bar, whereby upon longitudinal movement of said drawbar, the flexible means are selectively moved around said bedframe support and guide means and said reversing means to elevate or lower said bedframe supported thereby through shortening or lengthening the effective bedframe support portions of said flexible means; K. elevated position locking means for at least one end of said bedframe, said draw means being reversible and operable to raise or lower the bedframe end remote from the locked end thereof for obliquely positioning said bedframe; and L. frictional brake blocks, said flexible means comprising strands passing through said brake blocks, said brake blocks preventing slack in one said set of strands when the other set of said strands is withdrawn with the bedframe moving to an oblique position.

Claim 6

A bedstead comprising: A. a rigid rectangular undercarriage; B. a bedframe; C. upstanding posts at the corners of said undercarriage constituting first and second end post sets; D. first flexible means connected respectively to each said post of said first post set; E. second flexible means connected respectively to each said post of said second post set; F. first bedframe support and guide means for said first flexible means attached to said bedframe proximate one end thereof, said first flexible means extending around said first guide means and longitudinally inwardly along said undercarriage; G. second bedframe support and guide means for said second flexible means attached to said bedframe proximate the other end thereof; H. second flexible means reversing means on said bedframe positioned inwardly from said other end, said second flexible means extending around said second guide means, inwardly along said undercarriage, around said reversing means and longitudinally toward said other end substantially parallel to the longitudinally extended portion of said first flexible means; I. a longitudinally movable draw bar mounted transversely of said bedframe; J. the free ends of said first and second flexible means being attached to said draw bar, whereby upon longitudinal movement of said drawbar, the flexible means are selectively moved around said bedframe support and guide means and said reversing means to elevate or lower said bedframe supported thereby through shortening or lengthening the effective bedframe support portions of said flexible means; K. elevated position locking means for at least one end of said bedframe, said draw means being reversible and operable to raise or lower the bedframe end remote from the locked end thereof for obliquely positioning said bedframe; and L. frictional brake blocks, said flexible means comprising strands passing through said brake blocks, said brake blocks preventing slack in one said set of strands when the other set of said strands is withdrawn with the bedframe moving to an oblique position.

Claim 7

A bedstead as claimed in claim 4 including elevated position locking means at each end of said bedframe, said locking means being releasable only when both said ends are at maximum elevated position.

Claim 8

A bedstead as claimed in claim 5 including locking means for both ends of said bedframe, said locking means being interconnected and operable for selective alternative or conjoint locking engagement.

Claim 9

A bedstead as claimed in claim 6, said bedframe comprising a double-walled self-supporting structure including corner posts enclosing said upstanding posts on said undercarriage, detachable gables and sideboards on said structure, said flexible strands and guides being contained within said structure walls, said draw bar and the moving means therefor being enclosed within a housing interconnected between longitudinal sides of said bedframe.
