Waterbed frame structure

Claim 2

A waterbed frame structure comprising: a. a mattress support frame of open rectangular configuration having four wall members demountably interconnected by interlocking corner joints to form an endless upstanding wall; b. a planar platform for supporting said mattress support frame; and c. said interlocking corner joints of said mattress support frame each comprising, I. a tenon extending intermediately from the end of one of the wall members of said mattress support frame, Ii. an open mortise formed in the end of the adjacent wall member of said mattress support frame, said open mortise having a spaced pair of projections separated by a gap into which said tenon is slidably straddingly positioned, Iii. said tenon and said open mortise having a three segment bore formed therethrough with a first segment thereof formed through one of said pair of projections of said open mortise, a second segment thereof formed through said tenon, and a third segment thereof formed through the other one of said pair of projections of said open mortise, and Iv. an elongated headed pin slidably demountably positioned in said three segment bore formed through said tenon and said open mortise.

Claim 3

A waterbed frame structure as claimed in claim 1 wherein said tenon is located intermediate the end of the wall member of said mattress support frame from which it extends and has a height dimension which is approximately equal to one-third of the height dimension of that end.

Claim 4

A waterbed frame structure as claimed in claim 1 wherein said open mortise has a spaced pair of projections separated by a gap, said pair of projections and said gap each having a height dimension which is approximately equal to one-third of the height dimension of the end of the wall member of said mattress support frame in which said pair of projections and said gap are formed.

Claim 5

A waterbed frame structure comprising: a. a mattress support frame of open rectangular configuration having a spaced pair of parallel side wall members and a spaced pair of end wall members interconnected to said pair of side wall members by demountably interlocking corner joints; b. a planar platform upon which said mattress support frame is supported; c. a pedestal frame of open rectangular configuration supportingly positioned below said planar platform; and d. said interlocking corner joints of said mattress support frame comprising, I. a tenon extending from each of the opposite ends of each of the side wall members of said mattress support frame, Ii. an open mortise formed in each of the opposite ends of each of the end wall members of said mattress support frame, Iii. each of said open mortises straddingly mounted on a different one of said tenons, Iv. each of said open mortises and said tenons having a bore formed vertically therethrough, V. a headed pin demountably slidably positioned in each of the bores formed through said open mortises and tenons, and Vi. at least two of said tenons being elongated to extend beyond the ones of said open mortises which are straddlingly mounted thereon, said elongated tenons aligned to extend beyond one of the end wall members of said mattress support frame.

Claim 6

A waterbed frame structure comprising: a. a mattress support frame of open rectangular configuration having a spaced pair of parallel side wall members and a spaced pair of end wall members interconnected to said pair of side wall members by demountably interlocking corner joints; b. a planar platform upon which said mattress support frame is supported; c. a pedestal frame of open rectangular configuration supportingly positioned below said planar platform; and d. said interlocking corner joints of said mattress support frame comprising, I. a tenon extending from each of the opposite ends of each of the side wall members of said mattress support frame, Ii. an open mortise formed in each of the opposite ends of each of the end wall members of said mattress support frame, Iii. each of said open mortises straddingly mounted on a different one of said tenons, Iv. each of said open mortises and said tenons having a bore formed vertically therethrough, V. a headed pin demountably slidably positioned in each of the bores formed through said open mortises and tenons, and Vi. at least two of said tenons being elongated to extend beyond the ones of said open mortises which are straddlingly mounted thereon, said elongated tenons aligned to extend beyond one of the end wall members of said mattress support frame.

Claim 7

A waterbed frame structure as claimed in claim 4 and further comprising a headboard demountably attached to said pair of elongated tenons.

Claim 8

A waterbed frame structure as claimed in claim 4 and further comprising: a. a headboard of substantially planar configuration; b. an open mortise formed in each of the lower corners of said headboard; c. said headboard positioned so that each of said open mortises thereof are straddlingly mounted on a different one of said pair of elongated tenons; d. each of said open mortises of said headboard having a vertical bore formed therethrough; e. each of said pair of elongated tenons having a second vertical bore formed therethrough so as to align with the vertical bore of the one of said open mortises mounted thereon; and f. a pair of headed pins each demountably slidably positioned in a different one of the vertical bores formed in said open mortises of said headboard and in the one of said second bores of said tenons which align therewith.
