Abstract

A motorized furniture assembly having seat and back support sections moves between sofa and bed positions relative to a stationary frame by activation of two motorized drive assemblies. The motorized drive assemblies move seat support brackets of a seat section forward and backward relative to the stationary frame. Movement of the seat section moves a back support section between horizontal and raised positions. Two linkage assemblies control movement of the motorized furniture assembly between the sofa and bed positions upon actuation of said at least one actuator for activating the motorized drive assemblies.

First claim

What is claimed is:

1. A motorized furniture assembly movable between a sofa position and a bed position, the motorized furniture assembly comprising:
a stationary frame having two sides;
a seat section movable relative to the stationary frame, the seat section comprising two seat deck support brackets and a seat deck extending between the seat deck support brackets,
a back support section movable relative to the stationary frame, the back support section comprising back deck support brackets and a back deck extending between the back deck support brackets;
a power assembly for moving the furniture assembly between the sofa and bed positions, the power assembly comprising a power supply, a controller, at least one actuator;
two control assemblies, each control assembly including a motorized drive assembly and a linkage assembly joined to the motorized drive assembly for controlling movement of the seat and back support sections relative to the stationary frame, each of the motorized drive assemblies comprising a rotatable screw drive used to move a shuttle to move the seat and back support sections;
a universal bracket attached to each of the shuttles of each of the motorized drive assemblies, each of the universal brackets being secured to one of the seat deck support brackets such that movement of the shuttles moves the seat deck support brackets of the seat section which moves the back deck support brackets of the back support section;
two stationary mounting assemblies, one of the stationary mounting assemblies being secured to each side of the stationary frame, one of the motorized drive assemblies being mounted to each of the stationary mounting assemblies;
wherein the linkage assemblies control movement of the furniture assembly between the sofa and bed positions upon actuation of said at least one actuator, each of said linkage assemblies comprising a strong arm having a first end and a second end, the first end of the strong arm being pivotally connected to one of the seat deck support brackets and the second end of the strong arm being pivotally connected to one of the stationary mounting assemblies, and wherein movement of the shuttles of the motorized drive assemblies moves the seat section between forward and rearward positions which causes movement of the back support section between horizontal and raised positions, said linkage assembly further comprising:
a front arm having a first end and a second end, the first end of the front arm being pivotally connected to one of the stationary mounting assemblies;
an L-shaped arm having a first end and a second end, the first end of the L-shaped arm being pivotally connected to the second end of the front arm and the second end of the L-shaped arm being pivotally connected to one of the seat deck support brackets;
a connector arm having a first end and a second end, the first end of the connector arm being pivotally connected to the second end of the front arm and the first end of the L-shaped arm;
a swivel arm having an upper end and a lower end, the upper end of the swivel arm being pivotally connected to one of the stationary mounting assemblies and the lower end of the swivel arm being pivotally connected to the second end of the connector arm;
an intermediate arm having a front end and a rear end, the rear end of the intermediate arm being pivotally connected to the swivel arm between the upper and lower ends of the swivel arm;
a teeter arm having a front end and a rear end the front end of the teeter arm being pivotally connected to the front end of the intermediate arm;
a rear arm having an upper end and a lower end, the upper end of the rear arm being pivotally connected to one of the seat deck support brackets and the lower end of the rear arm being pivotally connected to the second end of the connector arm; and
an outer arm having a front end and a rear end, the front end of the outer arm being pivotally connected to the rear end of the teeter arm and the rear end of the outer arm being pivotally connected to the rear arm between the upper and lower ends of the rear arm.

2. The furniture assembly of claim 1 , wherein the back support section has an upper surface and a lower surface, the upper surface of the back support section being behind the lower surface of the back support section when the furniture assembly is in the sofa position.

3. The furniture assembly of claim 1 , wherein the seat section has a front surface and a rear surface, the front surface of the seat section being above the rear surface of the seat section when the furniture assembly is in the sofa position.

4. The furniture assembly of claim 1 , wherein each of the stationary mounting assemblies comprises a mounting piece and a motor mounting piece riveted to the mounting piece.

5. The furniture assembly of claim 4 , wherein the motor mounting piece of the stationary mounting assembly is angled relative to the mounting piece of the stationary mounting assembly.

6. The furniture assembly of claim 1 , wherein each of the stationary mounting assemblies comprises multiple pieces.

7. A motorized furniture assembly movable between a sofa position and a bed position, the motorized furniture assembly comprising:
a stationary frame including two sides;
a seat section movable relative to the stationary frame, the seat section comprising two seat deck support brackets and a seat deck,
a back support section movable relative to the stationary frame, the back support section comprising back deck support brackets and a back deck;
a power assembly for moving the furniture assembly between the sofa and bed positions, the power assembly comprising a power supply, a controller, at least one actuator;
two motorized drive assemblies, each of the motorized drive assemblies including a movable shuttle;
a stationary mounting assembly secured to each side of the stationary frame, one of the motorized drive assemblies being mounted to the stationary mounting assembly;
a universal bracket attached to the movable shuttle, one of the seat deck support brackets being secured to the universal bracket such that the seat section moves upon movement of the shuttles of the motorized drive assemblies;
two linkage assemblies for controlling movement of the furniture assembly between the sofa and bed positions upon actuation of said at least one actuator, each of said linkage assemblies comprising:
a strong arm having a first end and a second end, the first end of the strong arm being pivotally connected to one of the seat deck support brackets and the second end of the strong arm being pivotally connected to one of the stationary mounting assemblies,
a front arm having a first end and a second end, the first end of the front arm being pivotally connected to one of the stationary mounting assemblies;
an L-shaped arm having a first end and a second end, the first end of the L-shaped arm being pivotally connected to the second end of the front arm and the second end of the L-shaped arm being pivotally connected to one of the seat deck support brackets;
a connector arm having a first end and a second end, the first end of the connector arm being pivotally connected to the second end of the front arm and the first end of the L-shaped arm;
a swivel arm having an upper end and a lower end, the upper end of the swivel arm being pivotally connected to one of the stationary mounting assemblies and the lower end of the swivel arm being pivotally connected to the second end of the connector arm;
an intermediate arm having a front end and a rear end, the rear end of the intermediate arm being pivotally connected to the swivel arm between the upper and lower ends of the swivel arm;
a teeter arm having a front end and a rear end, the front end of the teeter arm bein
