Abstract
Abstract A reclinable chair is rockable on a sub-frame which is movable forwardly and rearwardly on a base. The chair and sub-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 sub-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 righthand side of the chair is raised 10 or 15°. The further movement of the handle extends the legrest forwardly of the seat. The weight of the occupant when seated in the chair assists in the movement of the chair to the forward position during which the downward movement of a Boden wire secured to the sprung surface of the seat or to a lever pivoted thereon releases the actuating element. The wire operates the element and unlatches the chair when in forward position as the occupant leaves the chair seat or operates the lever and permits a spring to return the chair to its rear latched position. A lever prevents the rocking of the chair until the chair reaches its forward position where it is stopped in its forward movement as it releases 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.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
149 words
In a wall reclining rocking chair, a sub-frame, a base for said sub-frame, a rockable chair embodying a back, seat and frame mounted on said sub-frame, means on said base sloping downwardly at the forward end on which said sub-frame is supported for forward and downward movement, a pair of links having the adjacent ends pivoted together, means for pivoting one end of one link to the base and the other end of the other link to said sub-frame in a manner to permit them to move into aligned locking relation one above and in extension of each other for locking the chair in rearward and forward positions, and means actuated when the sub-frame is locked at the forward and rearward positions for deflecting the two links out of alignment when disposed one above the other and in extension of each other for releasing said lock in both positions.
Claim 2
Dependent Claim
149 words
In a wall reclining rocking chair, a sub-frame, a base for said sub-frame, a rockable chair embodying a back, seat and frame mounted on said sub-frame, means on said base sloping downwardly at the forward end on which said sub-frame is supported for forward and downward movement, a pair of links having the adjacent ends pivoted together, means for pivoting one end of one link to the base and the other end of the other link to said sub-frame in a manner to permit them to move into aligned locking relation one above and in extension of each other for locking the chair in rearward and forward positions, and means actuated when the sub-frame is locked at the forward and rearward positions for deflecting the two links out of alignment when disposed one above the other and in extension of each other for releasing said lock in both positions.
Claim 3
Dependent Claim
48 words
In a wall reclining rocking chair as recited in claim 1, wherein an actuating element is secured on the pivot attaching the link to the sub-frame for deflecting the links out of alignment when disposed one above and in extension of each other when rotated about said pivot.
Claim 4
Dependent Claim
77 words
In a wall reclining rocking chair as recited in claim 1, wherein a mechanism is provided on said chair to keep it from rocking forwardly and rearwardly except when the chair is in forward position where it is locked against forward and rearward rocking movement by the two said pivoted links when disposed in extension of each other. stopped during the final forward movement of the chair for releasing said mechanism to permit said chair to rock.
Claim 5
Dependent Claim
25 words
In a wall reclining rocking chair as recited in claim 3, wherein a stop plate is secured to a lever on said mechanism which is
Claim 6
Dependent Claim
123 words
In a wall reclining rocking chair as recited in claim 4, wherein said lever is fixed to said stop plate, a pivot on said stop plate, a bracket on said sub-frame having a horizontal slot in which said pivot is movable forwardly and rearwardly, a spring for advancing the pivot of said stop plate in said slot toward the front of the chair, and means on said base engaged by said plate near the end of the forward movement of said sub-frame to permit the bracket and mechanism to continue to move forwardly as the stop plate and link are held stationary to release the mechanism and permit the rocking of the chair when the chair and sub-frame are locked in forward position.
Claim 7
Dependent Claim

In a wall reclining rocking chair as recited in claim 1, wherein a legrest is actuated by a handle to extended position, and means operated by the initial movement of the handle to operate the actuating means and release the links from locked position when disposed one above the other to permit the weight of the chair occupant to move the chair and sub-frame to the locked front position.
Claim 8
Dependent Claim
93 words
In a wall reclining rocking chair as recited in claim 2, wherein a Boden unit has its tubular element fixed to said chair at one end and to the sub-frame at the other end with the end of the wire located adjacent to the chair secured to the sprung area of the seat and the end adjacent to said sub-frame secured to said actuating element so that when the wire moves upwardly at the time the seat becomes unoccupied the actuating element will be operated to move the links out of aligned position.
Claim 9
Dependent Claim
41 words
In a wall reclining rocking chair as recited in claim 7, wherein a plurality of sinuous springs form the sprung area of the seat, the rear end of one of said springs having the wire of the Boden unit secured thereto.
Claim 10
Dependent Claim
57 words
In a wall reclining rocking chair as recited in claim 8, wherein the wire of the Boden unit is moved downwardly when the seat is occupied to release the actuating element and is moved upwardly when the seat is unoccupied to operate the actuating element and release the lock which secures the chair in the front position.
Claim 11
Dependent Claim
