Claim 8

A bed frame construction particularly adapted for supporting a waterfilled bladder type mattress, said frame construction being adapted to be supported on a subframe comprising two spaced apart frame rails, said frame construction including: opposed parallel longitudinal side frame members; opposed parallel transverse end frame members; means for securing said side and end frame members to each other to form a generally rectangular open top enclosure for containing said mattress against horizontal bulging; means for supporting said mattress comprising at least two elongated beam members adapted to be secured to the respective inner sides of one of said opposed side and end frame members, respectively, for supporting therebetween a generally horizontal deck member for supporting said mattress; and said side and end frame members each comprised of channel sections comprised of a channel shaped member having opposed flanges and an interconnecting web portion, said channel sections covered on their top and outer side surfaces by resilient cushion means, said resilient cushion means being formed to have a generally horizontally extending slot therein along said frame members and at least one of said end frame members for receiving a tuck of an article of bedclothing for retaining said article covering a sleeping surface of said mattress.

Claim 9

The bed frame construction set forth in claim 5 including: at least one elongated beam member extending parallel to and aligned with said two beam members and secured to respective ones of the other of said side and end frame members at its opposite ends, respectively, and supportive of said deck.

Claim 10

The bed frame construction set forth in claim 5 wherein: said side and end frame members include means along the outer sides thereof for receiving a tuck of an article of bedclothing for retaining said article covering said mattress across the top of said enclosure.

Claim 11

In a waterbed construction, a perimeter frame including a substantially rigid frame member comprising elongated channel shaped beam means extending around the periphery of a waterfilled bladder type mattress, said beam means including a web extending vertically between substantially horizontal outwardly projecting spaced apart flanges, resilient cushion pad means extending along the outer side of said beam means between said flanges, said pad means being formed to include a slot extending substantially horizontally along said outer side of said frame member and comprising means for receiving a tuck of an article of bedclothing for retaining said article covering a sleeping surface of said mattress.

Claim 12

In a waterbed construction, a perimeter frame including a substantially rigid frame member comprising elongated channel shaped beam means extending around the periphery of a waterfilled bladder type mattress, said beam means including a web extending vertically between substantially horizontal outwardly projecting spaced apart flanges, resilient cushion pad means extending along the outer side of said beam means between said flanges, said pad means being formed to include a slot extending substantially horizontally along said outer side of said frame member and comprising means for receiving a tuck of an article of bedclothing for retaining said article covering a sleeping surface of said mattress.

Claim 13

The waterbed construction set forth in claim 8 wherein: said frame member comprises an upward facing perimeter surface around the edge of said mattress, said surface including cushion pad means extending at least partially therealong.

Claim 14

The waterbed construction set forth in claim 9 wherein:

Claim 15

said frame includes a fabric cover disposed over said cushion pads on said frame member and extending into said slot.

Claim 16

said frame includes a fabric cover disposed over said cushion pads on said frame member and extending into said slot.

Claim 17

The waterbed construction set forth in claim 12 wherein: said frame member comprises a substantially rectangular box shaped structure enclosing the sides of said mattress and comprising elongated parallel side members and opposed parallel end members joined together at their respective adjacent ends to form said beam means, said slot extending along the outer sides of said side and end members to form a continuous slot around the periphery of said frame.

Claim 18

The waterbed construction set forth in claim 11 wherein: said side and end members are joined by corner bracket means at said respective adjacent ends.

Claim 19

The waterbed construction set forth in claim 11 wherein: said frame comprises mattress support means including a plurality of elongated beams extending parallel to the lower sides of one of said side members and end members, means forming a mattress support deck supported on said beams and adapted to support a bottom side of said mattress.
