Adjustable foundation and mattress assembly
First Claim
1. A coil spring mattress and adjustable foundation assembly, comprising:
- a coil spring mattress; and
an adjustable foundation frame comprising;
side frame members and transverse frame members attached at respective ends of the side frame members to define a generally rectangular shape, and at least one cross rail extending between the side frame members;
a mattress support surface including a head and back section hingedly connected to an intermediate seat section at one end and a leg and foot section hingedly connected to the intermediate seat section at another end, wherein the intermediate seat section includes a first portion and a second portion, wherein the first portion is hingedly connected to the head and back section and the second portion is hingedly connected to the leg and foot section; and
a first actuator having an extending and retracting member operatively coupled to a linkage assembly to effect inclination or declination of the head and back section relative to the intermediate seat section and inclination or declination of the foot and leg section, wherein the first actuator is further operative to effect an increase or decrease in a length of the intermediate seat section by movement of the first portion relative to the second portion.

Abstract
A coil spring mattress and adjustable foundation assembly includes a coil spring mattress; and an adjustable foundation including a mattress support surface including a head and back section hingedly connected to an intermediate section at one end and a leg and foot section hingedly connected to the intermediate section at another end, wherein the intermediate section includes a first portion and a second portion. The intermediate or seat section is configured to increase in length upon articulation of the head and back section and/or the leg and foot section from a flat position or an increase in inclination of any section. Likewise, the intermediate or seat section is configured to decrease in length upon articulation of the head and back section and/or the leg and foot section from an inclined position to a flat position or a decrease in length upon declination of any section.

9. A coil spring mattress and adjustable foundation assembly, comprising:
-
a coil spring mattress; and an adjustable foundation frame comprising; side frame members and transverse frame members attached at respective ends of the side frame members to define a generally rectangular shape, and at least one cross rail extending between the side frame members; a mattress support surface including a head and back section hingedly connected to an intermediate seat section at one end and a leg and foot section hingedly connected to the intermediate seat section at another end, wherein the intermediate seat section includes a first portion and a second portion, wherein the first portion is hingedly connected to the head and back section and the second portion is hingedly connected to the leg and foot section; a first actuator underlying the intermediate seat section having an extending and retracting member operatively coupled to a linkage assembly to effect selective inclination or declination of the head and back section relative to the intermediate seat section, wherein the first actuator is further operative to effect an increase or decrease in a length of the intermediate seat section by movement of the first portion relative to the second portion, and wherein the linkage assembly comprises a linkage support frame configured to be seated on the foundation frame;
first and second spaced apart torsional members coupled to the linkage support frame underlying each end of the intermediate seat section;
cross bars coupled to the linkage support frame and underlying each of the first and second torsional members, and link arms having an end pivotally connected to crank arms coupled to the first and/or second torsional members, wherein the first actuator has one end coupled to one of the cross bars and another end coupled to one of the crank arms effective to rotate the first torsional member upon extension and retraction of the first actuator and effect inclination or declination of the head and back section; anda second actuator having an extending and retracting member operatively coupled to the linkage assembly to effect selective inclination or declination of the leg and foot section. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)
