Abstract
A drive mechanism for an article of adjustable furniture, the drive mechanism having support sections, the support sections including a first support section and a second support section, an actuator mechanism, and at least one connecting mechanism, the at least one connecting mechanism includes a first arm pivotally connected to the first support section, and a second arm pivotally connected to the second support section, the first arm being pivotally connected to the second arm, in which the actuator mechanism is drivingly connected to the second support section to effect concertina-like movement between the first arm and the second arm to move the second support section relative to the first support section.

A drive mechanism (7) for an article of adjustable furniture (10), the drive mechanism (7) comprising:
- a plurality of support sections, said support sections including a first support section (12) and a second support section (14), an actuator mechanism (16), and at least one connecting mechanism (18), the at least one connecting mechanism (18) includes a first arm (20) pivotally connected to the first support section (12), and a second arm (22) pivotally connected to the second support section (14), the first arm (20) being pivotally connected to the second arm (22), wherein the actuator mechanism (16) is drivingly connected to the second support section (14) to effect a concertina-like movement between the first arm (20) and the second arm (22) to move the second support section (14) relative to the first support section (12), wherein:
- the concertina-like movement between the first arm (20) and the second arm (22) causes one of a relative linear and a rotational movement between the first (12) and second (14) support sections;
- and wherein:
- the concertina-like movement between the first aim (20) and the second aim (22) causes coordinated simultaneous linear and rotational movement of the second support section (14) relative to the first support section (12).
A drive mechanism (7) for an article of adjustable furniture (10), the drive mechanism (7) comprising:
- a plurality of support sections, said support sections including a first support section (12) and a second support section (14), an actuator mechanism (16), and at least one connecting mechanism (18), the at least one connecting mechanism (18) includes a first arm (20) pivotally connected to the first support section (12), and a second arm (22) pivotally connected to the second support section (14), the first arm (20) being pivotally connected to the second arm (22), wherein the actuator mechanism (16) is drivingly connected to the second support section (14) to effect a concertina-like movement between the first arm (20) and the second arm (22) to move the second support section (14) relative to the first support section (12);
- further comprising:
- a drive arm (26) connecting the first (12) and second (14) support sections, wherein the actuator mechanism (16) is pivotally connected to the drive arm (26) to drivingly connect the actuator mechanism to the second support section (14);
- and
- wherein:
- the drive arm (26) comprises a first drive arm (28) and second drive arm (30), the first drive arm (28) is pivotally connected to the first support section (12) at a first drive arm pivotal connection (31), the second drive arm (30) is pivotally connected to the second support section (14) at a second arm pivotal connection (33), and the first drive arm (28) is pivotally connected to the second drive arm (30) at a connecting arm pivotal connection (32), such that movement of the actuator mechanism (16) effects concertina-like movement between the first drive arm (28) and second drive arm (30) when the second support section (14) moves relative to the first support section (12).
A drive mechanism (7) for an article of adjustable furniture (10), the drive mechanism (7) comprising:
- a plurality of support sections, said support sections including a first support section (12) and a second support section (14), an actuator mechanism (16), and at least one connecting mechanism (18), the at least one connecting mechanism (18) includes a first arm (20) pivotally connected to the first support section (12), and a second arm (22) pivotally connected to the second support section (14), the first arm (20) being pivotally connected to the second arm (22), wherein the actuator mechanism (16) is drivingly connected to the second support section (14) to effect a concertina-like movement between the first arm (20) and the second arm (22) to move the second support section (14) relative to the first support section (12), wherein:
- the first arm (20) is pivotally connected to the first support section (12) at a first arm pivot point (42) to define a first arm extension section (44), wherein the concertina-like movement between the first arm (20) and the second arm (22) engages the first arm extension section (44) with the first support section (12) to support the second support section (14) relative to the first support section (12).
