  • Patent number: 5769500
    Abstract: A segment and frame for furniture and a method of assembling the furniture are provided which allow easy installment and removal of the segment by an individual. The segment preferably has rib-like side portions which are received into channels formed on the frame. The length of the segment is substantially the same as the distance between the frame members, so that the need for heating, stretching, and cooling of the segment for attachment to the frame is eliminated, and the assembly or disassembly can easily be performed by a single person. That is, one person can easily attach and secure the segment to the frame without special equipment or using fasteners such as screws or rivets. A single, wide segment or a plurality of segments may be used for the furniture, and decorative surfaces and cutouts can be included in the segments to create a stylish look.

  • Patent number: 5765914
    Abstract: A synchronous tilt control mechanism is provided for a chair. The chair includes a base, a seat, a back, a torsion spring, a first slide member and a second slide member. The base further includes a tilt control housing mounted thereon. The back includes a forwardly extending support member. The seat and back are pivotally attached to the tilt control housing. The torsion spring has a forwardly extending leg and a rearwardly extending leg. The forwardly extending leg is mounted to the tilt control housing. The seat slidably engages the support member by way of the first slide member, which is disposed on one of the seat and the support member. The support member slidably engages the rearwardly extending leg of the torsion spring by way of the second slide member, which is disposed on one of the support member and rearwardly extending leg. A downward movement of the seat causes the back to move downwardly and rearwardly against an upward force provided by the torsion spring.
