Abstract Furniture in the form of a chair, loveseat or couch is provided with a frame having at least one removable cushion. The cushion has oppositely disposed grooves. Each groove is adapted to receive a tongue on a frame of the furniture. A latch mechanism is provided within the cushion for cooperating with mating structure on an associated tongue whereby the cushion may be removed and replaced by another similar cushion or may merely be turned over and reinstalled in the furniture.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
130 words
Furniture of the chair, loveseat and couch type comprising a frame having at least one removable cushion, said cushion having oppositely disposed grooves, a pair of tongues on said frame, each tongue projecting into one of said grooves, latch means within said cushion, said latch means including a latch member projecting into at least one of the grooves on the cushion for latching cooperation with mating structure on the associated tongue, an actuator on the cushion connected to the latch member for releasing the latch member so that the cushion may be removed, a plate having a non-circular keyhole attached to said cushion, said actuator being aligned with said keyhole for reception of a key and being generally perpendicular to said latch member at a rear end of said cushion.
Claim 2
Dependent Claim
130 words
Furniture of the chair, loveseat and couch type comprising a frame having at least one removable cushion, said cushion having oppositely disposed grooves, a pair of tongues on said frame, each tongue projecting into one of said grooves, latch means within said cushion, said latch means including a latch member projecting into at least one of the grooves on the cushion for latching cooperation with mating structure on the associated tongue, an actuator on the cushion connected to the latch member for releasing the latch member so that the cushion may be removed, a plate having a non-circular keyhole attached to said cushion, said actuator being aligned with said keyhole for reception of a key and being generally perpendicular to said latch member at a rear end of said cushion.
Claim 3
Dependent Claim
39 words
Furniture in accordance with claim 1 wherein said actuator has a pair of axially extending projections on an end face thereof adjacent said keyhole to facilitate pivoting the actuator about its longitudinal axis upon contact with a mating key.
Claim 4
Dependent Claim
27 words
Furniture in accordance with claim 1 wherein at least one of said tongues is attached to the inner surface of a vertically disposed end of said frame.
Claim 5
Dependent Claim
54 words
Furniture in accordance with claim 1 wherein said cushion is a seat cushion, a back cushion supported by said frame, said back cushion being in overlying relationship with the innermost end of the seat cushion so that an actuator associated with the latch means in the back cushion is obscured by said seat cushion.
Claim 6
Dependent Claim
26 words
Furniture in accordance with claim 1 wherein said mating structure on the tongue is a shoulder at a notch adjacent the innermost end of said tongue.
Claim 7
Dependent Claim
43 words
Furniture in accordance with claim 1 wherein said removable cushion is a seat cushion, said frame having a back cushion, the lowermost corners of said back cushion being rectangular with the bottom surface of the back cushion being perpendicular to the sides thereof.
Claim 8
Dependent Claim
145 words
Furniture comprising a frame having at least two removable seat cushions which are generally horizontally disposed side-by-side and at least two removable back cushions which are generally vertically disposed side-by-side, each seat cushion abutting one of the back cushions, each cushion having oppositely disposed grooves which are exposed and extend for a length shorter than the length of the cushions, latch means within each cushion, each latch means including a pair of latch members, each latch member projecting into a separate one of the grooves on its associated cushion for latching cooperation with mating rails on the frame, an actuator in each cushion and connected to its associated latch members for releasing the associated latch members so that the cushions may be removed from the frame, said back cushions resting on said seat cushions so that their latch means are obscured by said seat cushions.
Claim 9
Dependent Claim
145 words
Furniture comprising a frame having at least two removable seat cushions which are generally horizontally disposed side-by-side and at least two removable back cushions which are generally vertically disposed side-by-side, each seat cushion abutting one of the back cushions, each cushion having oppositely disposed grooves which are exposed and extend for a length shorter than the length of the cushions, latch means within each cushion, each latch means including a pair of latch members, each latch member projecting into a separate one of the grooves on its associated cushion for latching cooperation with mating rails on the frame, an actuator in each cushion and connected to its associated latch members for releasing the associated latch members so that the cushions may be removed from the frame, said back cushions resting on said seat cushions so that their latch means are obscured by said seat cushions.
Claim 10
Dependent Claim
53 words
Furniture in accordance with claim 7 wherein each actuator has a pair of axially extending projections on an end thereof, a plate having a non-circular keyhole attached to each cushion adjacent said end of its associated actuator, said projection being adapted to cooperate with a key to facilitate movement of said latch members.
Claim 11
Dependent Claim
29 words
Furniture in accordance with claim 7 wherein the rails for the seat cushions are tilted so that the rear ends of the rails are lower than the front ends.
Claim 12
Dependent Claim
