Abstract
A sofa bed with three moving seat bases that transforms between a bed configuration and a sofa configuration. The sofa bed includes supporting legs and armrest. The armrest does not extend to the floor and allows the set of rails to form a notch such that the back end of the sofa bed may be installed on a raised area. Each of the seat bases, and corresponding cushions, are located between the armrests. The seat bases are interconnected with a set of slide rails that allow the seat bases to move relative to one another. The sofa bed also includes a locking mechanism to hold the sofa bed in the sofa configuration.

A sofa bed configured to be installed in a recreational vehicle (RV) having a floor and a movable raised surface, the sofa bed extendable between a sofa configuration and a bed configuration, comprising:
- a pair of armrests, wherein the pair of armrests form a notch configured to receive the movable raised surface therein and the pair of armrests are not configured to extend to the floor of the RV;
- at least one first seat cushion disposed between the pair of armrests;
- at least one first connector attached to each of the at least one first seat cushion;
- at least one second seat cushion disposed between the pair of armrests;
- at least one second connector attached to each of the at least one second seat cushion, wherein the at least one first connector and the at least one second connector form a hinge joint;
- at least one third seat cushion disposed between the set of armrests;
- a first seat base attached to the at least one first seat cushion;
- a pair of stand bars supporting the first seat base;
- a second seat base attached to the at least one second seat cushion;
- a third seat base attached to the at least one third seat cushion, wherein the second seat base and the third seat base are connected in a hinge joint;
- a pair of rotating shafts, each disposed in one of the armrests, wherein that third seat base is attached to rotating shafts opposite the hinge joint with the second seat base;
- a pair of support legs configured to support the first seat base;
- a pair of first slide rails, each attached to one of the pair of support legs;
- a pair of first glide wheels, each connected to one of the first connectors, wherein each of the first slide rails is configured to receive the first glide wheel and allow the first glide wheel to roll along at least part of the length of the first slide rail to permit the sofa bed to transition between the sofa configuration and the bed configuration;
- a pair of second slide rails, each attached to one of the pair of armrests;
- and
- a pair of second glide wheels, each of the second glide wheels connected to one of the first slides, wherein each of the second slide rails slides is configured to receive the second glide wheel and allow the second glide wheel to roll along at least part of the length of the second slide rail to permit the sofa bed to transition between the sofa configuration and the bed configuration.
A sofa bed configured to be installed in a recreational vehicle (RV) having a floor and a movable slide-out floor, the sofa bed extendable between a sofa configuration and a bed configuration, comprising:
- a pair of armrests, wherein the pair of armrests form a notch configured to receive the movable slide-out floor therein and the pair of armrests are not configured to extend to the floor of the RV;
- at least a first and second seat cushion disposed between the pair of armrests;
- a pair of support legs each having a caster, wherein the support legs are configured to enable the sofa bed to glide between the sofa configuration and the bed configuration;
- a pair of first slide rails, wherein each of the first slide rail is attached to one of the pair of support legs;
- a pair of first glide wheels connected to the first seat cushion, wherein each of the first slide rails is configured to receive the first glide wheel and allow the first glide wheel to roll along at least part of the length of the first slide rail to move the support legs between the sofa configuration and the bed configuration;
- a pair of second slide rails, wherein each of the second slide rails is attached to one of the pair of armrests;
- and
- a pair of second glide wheels connected to the second seat cushion, wherein each of the second slide rails is configured to receive the second glide wheel and allow the second glide wheel to roll along at least part of the length of the second slide rail to move the support legs between the sofa configuration and the bed configuration.
A method of extending a sofa bed configured to be installed in a recreational vehicle (RV) having a floor and a movable slide-out floor, the sofa bed extendable between a sofa configuration and a bed configuration, comprising:
- installing a sofa bed against a movable slide-out wall of an RV and upon a movable slide-out floor, the sofa bed having a pair of armrests, wherein the pair of armrests form a notch and receive the movable slide-out floor therein, wherein the pair of armrests are not configured to extend to the floor of the RV,
- at least a first and second seat cushion disposed between the pair of armrests,
- a first seat base attached to the at least one first seat cushion and a second seat base attached to the at least one second seat cushion;
- a pair of support legs each having a caster, wherein the support legs are configured to enable the sofa bed to glide between the sofa configuration and the bed configuration,
- a pair of first slide rails, wherein each of the first slide rail is attached to one of the pair of support legs,
- a pair of first glide wheels connected to the first seat cushion, wherein each of the first slide rails is configured to receive the first glide wheel and allow the first glide wheel to roll along at least part of the length of the first slide rail to move the support legs between the sofa configuration and the bed configuration,
- a pair of second slide rails, wherein each of the second slide rails is attached to one of the pair of armrests, and
- a pair of second glide wheels connected to the second seat cushion, wherein each of the second slide rails is configured to receive the second glide wheel and allow the second glide wheel to roll along at least part of the length of the second slide rail to move the support legs between the sofa configuration and the bed configuration;
- lifting the first seat base in the sofa configuration and moving the first seat base away from the pair of armrests to allow the first and second glide wheels to roll along at least part of the length of the first and second slide rails to move the support legs along the movable slide-out floor to the bed configuration.
