A rocker mechanism is provided for implementation with a chair assembly to enable forward and rearward rocking thereof. The rocker mechanism includes upper and lower castings resiliently interconnected by a pair of leaf springs extending at an angle therebetween. The leaf springs are assembled between the upper and lower castings to define first and second effective lengths of each leaf spring for providing first and second spring rates of each leaf spring. In this manner, rocking motion in a first direction may be more difficult than rocking motion in a second direction. Further, the angular configuration of the leaf springs between the upper and lower castings enables maximization of the lengths of the leaf springs within the rocker mechanism.

A swivel base lockout assembly for disabling the rotational degree of freedom provided by a swivel plate operably disposed between a stationary base and a chair frame is disclosed. The swivel base lockout assembly includes a threaded fastener extending between the stationary base and a support frame of the chair frame. A spacer bushing is concentrically disposed about the threaded fastener to maintain the substantially parallel orientation of the stationary base and the support frame.

A modular reclining chair having an improved chair frame assembly and improved pantograph linkage is disclosed. The chair frame assembly includes a hybrid front frame member assembly having a plywood front frame board and a pair of metal front frame brackets for interconnecting a pair of side frame assemblies to define a rigid box-like chair frame. The front frame member assembly is further interconnected with the actuation mechanism to provide an integrated chair frame assembly. The improved pantograph linkage is adapted to be readily removable from a fully assembled chair for facilitating field serviceability and repair without requiring partial or complete disassembly of the reclining chair.

A battery pack for providing a standby power source for use with powered motion furniture having an electric motor. The battery pack includes a housing defining a cavity within which a first battery and a second battery are disposed and electrically connected in series, a circuit board for regulating the charging and discharging of the first and second batteries, and a support member for securing the circuit board within the cavity. An umbilical cord is electrically connected to the circuit board and is electrically connectable to the electric motor in order to provide power to charge the first and second batteries when the electric motor is connected to a power source. Alternatively, when the electric motor is not connected to an operative power source, the batteries power the electric motor through the umbilical cord connection. The support member preferably consists of a spacer plate having a plate-like body portion defining a cut-out communicable with the positive or negative terminals of the first battery as well as a support arrangement for securing the circuit board.
摘要:
A chair including a power-assisted linear actuation drive mechanism having a cam guide which is linearly movable upon rotation of a shaft for selectively actuating a lift and tilt linkage mechanism, and for causing forward lifting and tilting movement of the chair when a motor of the mechanism is operated in a first direction. Rotation of a shaft in a second opposite direction acts to lower the chair to a normal seating position. Continued rotation in the second direction causes a first cam block pivotably mounted to the cam guide to engage a first follower assembly for causing extension of a leg rest assembly and for causing a rearward tilt of the chair frame. Further rotation in the second direction causes a second cam block pivotably mounted to the cam guide to engage a second follower assembly for causing reclining movement of the chair and for causing an additional rearward tilt of the chair frame. This sequential operation of the leg rest assembly and the reclining linkage are independent and may be easily disabled to selectively eliminate either of the features.

An improved dual leg rest assembly is disclosed which is adapted for use in single and multi-person articles of furniture (i.e., chairs, sectionals, sofas, loveseats, etc.). More particularly, an improved linkage mechanism is provided for causing coordinated articulating movement of a primary leg rest panel and a secondary leg rest panel (i.e., mid-ottoman).

A modular reclining chair and method for assembling it are disclosed. The reclining chair seat assembly includes an improved seat frame which can be readily adapted for use with a variety of recliner chair configurations. The recliner chair seat assembly further includes a unique seat cushion that can be releaseably attached to a seat frame to facilitate assembly and service of the reclining chair.
摘要:
A rocking chair having a chair frame operable for providing rocking motion relative to a stationary base is provided. The rocking chair generally comprises a chair frame and a stationary base coupled together by a rocker spring assembly. The rocker spring assembly includes an upper and lower bracket having a pair of springs and means for suppressing the noise generated by the springs. The rocker spring assembly further includes means for limiting the rocking movement of the chair frame disposed between the upper and lower bracket of the rocker spring assembly. The present invention further includes means for suppressing the noise generated by other spring elements associated with a reclining or rocking/reclining chair.
摘要:
A swivel recliner/rocker chair which even more effectively resists unwanted rocking of the swivel base member thereof when the chair is rocked forwardly of the swivel base member, and which further is limited in its rearward reclining or rocking motion to a predetermined degree so as to thereby limit rocking of the swivel base member that might occur if the chair is reclined or rocked rearwardly of the swivel base member to an excessive degree. The chair includes a pair of rocker blocks having a flat section formed thereon and a pair of spring assemblies having upper and lower bracket members. The upper bracket members are secured to the rocker blocks and the lower bracket members are secured to side members of a base assembly such that the rocker blocks rock on the side members during reclining or rocking movement of the chair. The upper and lower bracket members are further secured to their respective rocker blocks and side members such that each spring assembly exerts a slight tensioning force to urge the seating section of the chair into a slightly reclined position even when there is no occupant seated in the chair. This substantially eliminates any possibility of forward rocking motion of the swivel base member when the chair is rocked forwardly. The flat portions of each rocker block further serve to limit the maximum reclining and rearward rocking movement of the seating section to thereby avoid any undesirable rocking of the swivel base member as the seating section is reclined or rocked in a rearward direction.
