Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
101 words
A chaise longue comprising, an integral back and rocker, an integral footrest and rocker, a seat pivotally attached to the back and the footrest at a pivot point above the rockers, each rocker being adapted to make contact with a supporting surface below its respective pivot point to support the chaise longue above the supporting surface and means for releasably locking the seat to the back in a selected one of a plurality of positions whereby the chaise lounge may, when the locking means is released, be rocked by an occupant, or locked by the occupant in a desired fixed position.
Claim 2
Dependent Claim
101 words
A chaise longue comprising, an integral back and rocker, an integral footrest and rocker, a seat pivotally attached to the back and the footrest at a pivot point above the rockers, each rocker being adapted to make contact with a supporting surface below its respective pivot point to support the chaise longue above the supporting surface and means for releasably locking the seat to the back in a selected one of a plurality of positions whereby the chaise lounge may, when the locking means is released, be rocked by an occupant, or locked by the occupant in a desired fixed position.
Claim 3
Dependent Claim
28 words
A chair as defined in claim 1 wherein the rocker means are formed to permit rocking of the back from a horizontal position approximately 80* from the horizontal.
Claim 4
Dependent Claim
44 words
A chair as defined in claim 1 wherein the locking means include a friction clutch at the pivot between the back and the seat, and screw means for adjusting the clutch to vary its resistance to relative movement between the back and the seat.
Claim 5
Dependent Claim
67 words
A chair as defined in claim 1 wherein the friction clutch comprises a first clutch member on one of the seat and the back, and a second clutch member on the other of the seat and the back, and a screw passing through the first member and threaded into the second member, the screw serving as a pivot and to adjust the pressure between the clutch members.
Claim 6
Dependent Claim
60 words
A chair as defined in claim 1 wherein the locking means comprises first and second locking members mounted on the back and the seat, respectively, and a locking sleeve axially slidable from a position wherein it embraces one of the first and second locking members to a position wherein it embraces both of said members to prevent relative rotation therebetween.
Claim 7
Dependent Claim
36 words
A chair as defined in claim 5 wherein each member is a regular polygon, the sleeve having an internal surface adapted to mate with the polygon to prevent relative rotation between the sleeve and the members.
Claim 8
Dependent Claim
90 words
A chair as defined in claim 1 wherein each rocker includes a semi-circular portion, the back and the footrest in side elevation extending tangentially from an end of the respective rocker, the center point of the semi-circle being on a perpendicular line drawn downwardly from each pivot point, whereby, as the back is moved upward from the horizontal position, the point at which the rocker meets the supporting surface shifts rearwardly in relation to the pivot, and whereby the rear of the seat moves downwardly as the back moves upward.
Claim 9
Dependent Claim
85 words
A chair as defined in claim 7 wherein the locking means comprises first and second locking members mounted one on each of the back and the seat, and latch means non-rotatably mounted in one of said locking members and movable from a position wherein it engages with the other locking member thereby preventing relative rotation between saId first and second locking members, to a position wherein it is released from engagement with said other locking member and allows relative rotation between the two locking members.
Claim 10
Dependent Claim
46 words
A chair as defined in claim 8 wherein said first locking member incorporates radially disposed teeth, latch means being mounted on the other of said locking members and having a slot engageable with one of said teeth to prevent relative rotation between the two locking members.
Claim 11
Dependent Claim
97 words
A chair as defined in claim 9 wherein said latch means incorporates a handle remote from said slot and a spring positioned between said handle and the second locking member, whereby the latch means may be caused to move downward by the application of pressure to said handle and thereby the slot in said latch means may be disengaged from the teeth on the first locking member and wherein when said pressure is released the spring causes the locking pin to move upward and thereby re-engages the slot with one of the teeth on the first member.
