Abstract
Abstract A waterbed frame is formed of side rails having inner rigid support elements surrounded by resilient cushion material. All sides of the frame may be formed by such rails with the rigid elements being connected at the corners, so that the rigid elements are in effect floating in the cushion material. Alternatively, two such side rails may be attached to more conventional appearing foot and head boards.

Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
105 words
In a waterbed having a horizontal platform and a flexible bag containing liquid forming a mattress which is positioned on the platform, side rail means for the mattress comprising: an elongated rigid element; cushioning means forming a side frame member with said rigid element surrounding the top and sides of said rigid element for preventing direct impact with said rigid element by a user of said waterbed; and means for cushion floating said rigid element comprising resiliently deformable material on the bottom face of said elongated rigid element for preventing any but the end portions of said rigid element from contacting another rigid member directly.
Claim 2
Dependent Claim
105 words
In a waterbed having a horizontal platform and a flexible bag containing liquid forming a mattress which is positioned on the platform, side rail means for the mattress comprising: an elongated rigid element; cushioning means forming a side frame member with said rigid element surrounding the top and sides of said rigid element for preventing direct impact with said rigid element by a user of said waterbed; and means for cushion floating said rigid element comprising resiliently deformable material on the bottom face of said elongated rigid element for preventing any but the end portions of said rigid element from contacting another rigid member directly.
Claim 3
Dependent Claim
48 words
A waterbed construction of claim 1 including a pair of said side frame members, a head board and a foot board with the rigid elements in said side frame members being connected to said head board and foot board to form a rectangular frame for receiving the mattress.
Claim 4
Dependent Claim
35 words
The waterbed construction of claim 2 including means for connecting said rigid elements to said headboard and foot board in a manner to permit the rigid elements to move vertically while restraining their movement horizontally.
Claim 5
Dependent Claim
68 words
The waterbed construction of claim 3 including four of said side frame members arranged to form a rectangular frame for receiving said mattress, the ends of the rigid elements in each of said frame members being connected at the corners of said frame to form a rigid frame which is supported on resilient material and is covered with resilient material on its exterior and on its upper surface.
Claim 6
Dependent Claim
47 words
The waterbed construction of claim 1 wherein said side frame member has a vertical outer wall, a horizontal upper wall, a horizontal bottom wall which is wider than said upper wall, and an angled inner wall extending between the inner edges of said upper and lower walls.
Claim 7
Dependent Claim
22 words
The waterbed construction of claim 5 wherein said rigid element is embedded within said frame member having resilient material on all sides.
Claim 8
Dependent Claim
70 words
The waterbed construction of claim 1 wherein said side frame member includes an outer portion having a rectangular cross-section with said rigid element being embedded in said outer portion and including an inner section having substantially a right triangular cross-section with a vertical wall engaging the inner wall of the outer section, a horizontal wall engaging the mattress support, and an inner angled wall engaging the side of the mattress.
Claim 9
Dependent Claim
31 words
The waterbed construction of claim 1 wherein said rigid element is in the form of a board having a rectangular cross-section with the longer side of the board cross-section extending vertically.
Claim 10
Dependent Claim
14 words
The waterbed construction of claim 1 wherein said rigid element has a channel-shape cross-section.
Claim 11
Dependent Claim
17 words
The waterbed construction of claim 1 wherein said rigid element is a pole with a circular cross-section.
Claim 12
Dependent Claim
35 words
The waterbed construction of claim 1 wherein said side frame member is extruded with the rigid element being embedded within the side frame member covered by resilient material on all sides except for its ends.
Claim 13
Dependent Claim
55 words
The waterbed construction of claim 11 wherein said side frame includes an inner wall to be engaged by the mattress, with said inner wall extending upwardly and outwardly from the platform and said rigid element has a generally triangular cross-section with an inner wall extending generally parallel to the inner wall of the frame member.
Claim 14
Dependent Claim
30 words
The construction of claim 1 wherein the rigid element is about one half the height of the resilient member, and the element is vertically centered in the side frame member.
Claim 15
Dependent Claim
74 words
A waterbed construction comprising a headboard, a footboard, and a pair of side frame members attached to the head and footboards to form a rectangular frame, each of said side frame members being made of resilient material but having an elongated rigid element embedded in the resilient material, including resilient material extending beneath the lowest surface of the rigid element, and means connecting the ends of the rigid element to said headboard and footboard.
Claim 16
Dependent Claim
74 words
A waterbed construction comprising a headboard, a footboard, and a pair of side frame members attached to the head and footboards to form a rectangular frame, each of said side frame members being made of resilient material but having an elongated rigid element embedded in the resilient material, including resilient material extending beneath the lowest surface of the rigid element, and means connecting the ends of the rigid element to said headboard and footboard.
Claim 17
Dependent Claim
41 words
The waterbed construction of claim 14 wherein the connecting means includes means which permits the rigid elements to move vertically against the resilience of the material beneath the rigid elements but restrains the ends of said rigid elements from moving laterally.
Claim 18
Dependent Claim
93 words
A waterbed comprising: a horizontal platform; a waterbed mattress positioned on said platform; and a frame surrounding the sides of said mattress providing support for the edges of the mattress, said frame including a pair of side rails, each having a rigid support element and resilient cushion material positioned on top of the rigid element, on the bottom of the rigid element between the element and the horizontal platform to support the element on said platform and prevent the element from engaging the platform, and positioned on the outer side of the element.
Claim 19
Dependent Claim
93 words
A waterbed comprising: a horizontal platform; a waterbed mattress positioned on said platform; and a frame surrounding the sides of said mattress providing support for the edges of the mattress, said frame including a pair of side rails, each having a rigid support element and resilient cushion material positioned on top of the rigid element, on the bottom of the rigid element between the element and the horizontal platform to support the element on said platform and prevent the element from engaging the platform, and positioned on the outer side of the element.
Claim 20
Dependent Claim
35 words
The waterbed of claim 15 including four of said side rails arranged to form a rectangular frame with the rigid elements being joined at the corners to form a rigid frame supported on resilient material.
