Abstract
Abstract A reclinable chair is rockable on a frame which is movable forwardly on a base. The chair and frame are supported on the base on a pair of facing channels which slope downwardly from the rear to the front of the base. The frame and base are locked together in the rear and forward positions, the lock at the rear being released when the activating handle for the legrest at the side of the chair is raised 10° or 15°. The further movement of the handle extends the legrest forwardly of the seat. The seating of the occupant in the chair assists in the movement of the chair to the forward position during which a spring between the frame and base is tensioned for returning the chair to the rear position when the occupant leaves the seat and permits the springs of the seat to move upwardly and release the front latch. A lever prevents the rocking of the chair until it reaches the forward position where it is stopped in its forward movement to release the chair for rocking. When in forward position, the back of the chair may be reclined and the legrest may be extended in which position a ratchet mechanism becomes effective to prevent the chair from rocking or tilting forwardly.

Total Claims: 11
Claim 1
Independent Claim
135 words
In a wall reclining rocking chair, a base frame, a sub-frame, a rocker chair embodying a back and seat mounted on said sub-frame, means on said base frame sloping downwardly at the forward end on which said sub-frame is supported for forward movement by the weight of the occupant, lock means on said base frame for securing said sub-frame and rocker chair in rearward and forward positions, means for releasing said lock means at the rearward position when the seat is occupied, means for releasing said lock means at the forward position when the seat becomes unoccupied, means for returning said rocker chair and sub-frame to the rear position upon the seat becoming unoccupied, and means for preventing the rocking of the rocker chair both forwardly and rearwardly in all but its locked forward position.
Claim 2
Dependent Claim
135 words
In a wall reclining rocking chair, a base frame, a sub-frame, a rocker chair embodying a back and seat mounted on said sub-frame, means on said base frame sloping downwardly at the forward end on which said sub-frame is supported for forward movement by the weight of the occupant, lock means on said base frame for securing said sub-frame and rocker chair in rearward and forward positions, means for releasing said lock means at the rearward position when the seat is occupied, means for releasing said lock means at the forward position when the seat becomes unoccupied, means for returning said rocker chair and sub-frame to the rear position upon the seat becoming unoccupied, and means for preventing the rocking of the rocker chair both forwardly and rearwardly in all but its locked forward position.
Claim 3
Dependent Claim
67 words
In a wall reclining rocking chair as recited in claim 1, wherein a legrest supported on linkage means is operated by a shaft which is journaled in the chair frame and actuated by a handle at the side of the chair, and a finger on said legrest shaft for releasing said locking means at the rearward position of the rocker chair when the handle is slightly raised.
Claim 4
Dependent Claim
52 words
In a wall reclining rocking chair as recited in claim 1, wherein said locking means is a loosely mounted cross strap on the bottom of the sub-frame extending between the sides thereof, and a notched bracket on the base at the rearward and forward positions which are engaged by said cross strap.
Claim 5
Dependent Claim
64 words
In a wall reclining rocking chair as recited in claim 3, wherein said seat has sinuous spring units which deflect downwardly when occupied, said locking means being released from the notched bracket at the forward position when the weight of the occupant is removed from the seat permitting the sinuous spring units to move upwardly and raise the cross strap from the notched bracket.
Claim 6
Dependent Claim
110 words
In a wall reclining rocking chair as recited in claim 1, wherein the means for preventing the rocking of the rocker chair is a slot in a bracket in which one end of a pivoted latching member extends, said bracket being mounted at the front of the rocker chair, a link having one end pivoted to said latching member with the other end spaced from said base frame, and a member on said base frame for stopping the advancement of said link when the rocker chair is substantially in its forward position for withdrawing the latching member from said slot in said bracket to permit the rocker chair to rock.
Claim 7
Dependent Claim
42 words
In a wall reclining rocking chair as recited in claim 1, wherein the rocker chair back is pivotably connected to a seat which is advanced forwardly and upwardly when the back is reclined in the forward latched position of the rocker chair.
Claim 8
Dependent Claim
58 words
In a wall reclining rocking chair as recited in claim 6, wherein an extendable legrest is provided at the front of the chair, and a ratchet mechanism provided on the front of the rocker chair becomes effective when said legrest is extended and the chair is in forward position to prevent the chair from tilting forwardly or rocking.
