Abstract
A base for a chair is described. The example base for the chair includes a central support coupled to a seat of the chair, a first pair of legs extending radially from the central support, and a second pair of legs extending radially from the central support. The first pair of legs extend in a direction opposite the second pair of legs. A first angle between the first pair of legs is larger than a second angle between the second pair of legs. Respective legs of each of the first pair of legs and the second pair of legs are rotationally fixed relative to the seat of the chair.
Claims23
A base for a chair comprising:
- a non-rotating support to be coupled to a seat of the chair;
- a leg assembly comprising:
- a first pair of legs extending from the support, the first pair of legs defining an area under a front of the chair in which a user may position their feet;
- and
- a second pair of legs extending from the support in a direction opposite the first pair of legs, wherein a first angle between the first pair of legs is larger than a second angle between the second pair of legs;
- and
- a locking feature provided on the support to rotationally fix the leg assembly to the support.
A base comprising:
- a central support;
- a leg assembly comprising:
- a first pair of legs extending from the central support, each respective leg of the first pair of legs extending substantially toward a respective front corner of a seat;
- and
- a second pair of legs extending from the central support, each respective leg of the second pair of legs extending substantially toward a respective rear corner of the seat, wherein the first pair of legs defines a first angle, the second pair of legs defines a second angle, and the first angle is greater than the second angle;
- a locking feature provided on the central support to rotationally fix the leg assembly to the central support;
- and
- casters coupled to ends of each of the respective legs.
A seating device comprising:
- a non-rotating support to be coupled to a seat;
- and
- a leg assembly coupled to the non-rotating support, the leg assembly including a pair of legs defining an area under a front of the seating device, wherein an angle between the pair of the legs is at least 90 degrees, and the leg assembly is rotationally fixed relative to the non-rotating support by way of a positive locking feature.
