Abstract
Air bed assembly having a knockdown foundation made up of preassembled boxes which are used as shipping containers for the other elements of the bed, mattresses having interposed sets of isolated chambers for improved pressure distribution, contoured foam rails surrounding the mattresses and a visco-elastic foam pad overlying them, a cover with a removable pillow top enclosing the mattresses and foam, a blower assembly mounted inside one of the rails with control valves for supplying air to and removing air from the mattresses, and individual controls for returning the pressure in the mattresses to a desired level upon command and for preventing a drop in mattress pressure as the blower is turned on to increase that pressure.
Claims31
In an air bed:
- a knockdown foundation made up of preassembled boxes which prior to assembly of the bed are suitable for use as shipping containers for other elements of the bed;
- a pair of mattresses having interposed sets of isolated chambers resting on the foundation;
- contoured foam rails surrounding the mattresses;
- a visco-elastic foam pad overlying the mattresses;
- a cover with a removable pillow top enclosing the mattresses, rails and foam pad;
- a blower assembly mounted inside one of the rails with control valves for supplying air to and removing air from the mattresses;
- individual controls for the respective mattresses;
- means connected to the valves for returning the pressure in the mattresses to a desired level in response to a command issued through the controls;
- and means for controlling operation of the valves to prevent a drop in mattress pressure as the blower is turned on to increase the pressure within the mattresses.
6 more elements
In an air bed:
- a foundation;
- a pair of air inflatable mattresses disposed side-by-side on the foundation, each of the mattresses having first and second longitudinally extending chambers extending along opposite sides of the mattress, a first set of longitudinally spaced apart transversely extending chambers communicating with the first longitudinally extending chamber but not the second, a second set of longitudinally spaced apart transversely extending chambers interspersed between the transversely extending chambers of the first set and communicating with the second longitudinally extending chamber but not the first;
- a circumscribing frame of resilient foam in peripheral engagement with the mattresses;
- a visco-elastic foam pad overlying the mattresses for conforming to the contour of bodies resting thereon;
- a cover including a detachable pillow top enclosing the mattresses, frame and pad;
- and
- means including a blower assembly mounted in the foam frame for selectively introducing air into and removing air from each of the mattresses to individually control the firmness of the mattresses.
4 more elements
In an air bed:
- a mattress having first and second longitudinally extending chambers extending along opposite sides thereof, a first set of longitudinally spaced apart transversely extending chambers communicating with the first longitudinally extending chamber but not the second, a second set of longitudinally spaced apart transversely extending chambers interspersed between the transversely extending chambers of the first set and communicating with the second longitudinally extending chamber but not the first, and means for introducing air into the longitudinally and transversely extending chambers to inflate the mattress.
In an air bed:
- an air inflatable mattress having outwardly convex end and side walls, and a resilient circumscribing frame having end and side rails with concave inner walls defining a cavity for receiving the mattress with the convex walls of the mattress extending into and conforming to the concave inner walls of the rails.
In an air bed:
- an air inflatable mattress, a circumscribing frame having resilient head, foot and side rails surrounding the mattress with a recess in one of the rails, and a blower assembly mounted in the recess and connected to the mattress for introducing air into the mattress.
In an air bed:
- a blower assembly having an air chamber, an air inlet and an air outlet in communication with the chamber, a blower for drawing air into the chamber through the inlet, a valve controlling communication through the outlet;
- means for connecting the outlet of the blower assembly in communication with an air inflatable mattress;
- a controller;
- and
- means responsive to the controller for opening the valve when the blower is on to increase air pressure within the mattress and for opening the valve while the blower is off to vent air from the mattress through the air inlet and thereby decrease the air pressure within the mattress.
2 more elements
In an air bed:
- an air inflatable mattress, a blower, an air line connected between the blower and the mattress, a valve for controlling communication through the air line, a controller for actuating the blower to increase air pressure within the mattress, and means for opening the valve after the blower is actuated and pressure in the blower has built up to a level at least as great as the pressure within the mattress.
In an air bed:
- a foundation having two outer sections and a center section each of which is in the form of a generally rectangular inverted box having end walls, side walls and a generally planar top wall, the two outer sections being spaced from the center section with the side walls of the center section parallel to the side walls of the outer sections, intermediate upright members extending between the end walls of the outer sections and the center section, and intermediate platform members extending between the top walls of the outer sections and the center section to form a platform for supporting an air inflatable mattress.
