Retractable foot caster supports
First Claim
1. A bed, comprisinga base,a frame supported by the base,a deck supported by the frame, the deck being configured to support a mattress, the deck including at least one deck section being pivotable from a first position to a second position in which the deck section is at an angle relative to the base, anda plurality of casters supporting the base, the base having a first length extending along a longitudinal axis of the base and a second length extending along the longitudinal axis of the base, the second length being shorter than the first length, and the base being substantially parallel to the longitudinal axis of the bed when the base has the first length and when the base has the second length.

Abstract
A bed has a head section and a foot section. The bed can assume a horizontal position and at least one position in which the foot section is at an angle relative to horizontal. For instance, the bed may assume a chair position, in which the head section is pivoted upwardly and the foot section is pivoted downwardly, to a substantially vertical position.
Casters allow the bed to move relative to the floor. The casters can retract toward the head section of the bed as the foot section pivots downwardly toward the floor.

6. A bed, comprising
a base having a head end and a foot end spaced from the head end, a deck supported by the base, the deck being configured to support a mattress, the deck including a foot section adjacent the foot end of the base, the foot section being movable from a substantially horizontal position to a substantially vertical position, a first caster supporting the head end of the base, and a second caster supporting the foot end of the base, the second caster being spaced from the first caster by a first distance along a longitudinal axis of the bed when the foot section is in the substantially horizontal position and spaced from the first caster by a second distance along the longitudinal axis of the bed when the foot section is in the substantially vertical position, and the foot end of the base being substantially parallel to the longitudinal axis of the bed when the base has the first length and when the base has the second length.

11. A bed, comprising
a base having a head end and a foot end spaced from the head end, a deck supported by the base, the deck being configured to support a mattress, the deck including an articulating foot section, a caster support coupled to the foot end of the base, the caster support being movable along a longitudinal axis of the bed between a first position and a second position spaced from the first position by a distance, the distance being adjustable as the foot section articulates, and a caster coupled to the caster support, wherein the caster support is substantially parallel to the longitudinal axis of the bed when the base has the first length and when the base has the second length.
-
15. A bed, comprising
a plurality of casters, a base supported by the casters, the base having a head end, a foot end spaced from the head end, and an adjustable length, a deck configured to support a mattress, the deck being supported by the base, the deck including a foot section, the foot section being movable from a first position in which the foot section is substantially parallel to the base to a second position in which the foot section is at an angle relative to the base, and a controller configured to change the length of the base if the foot section has moved, wherein the base is substantially parallel to a longitudinal axis of the bed when the foot section is in the first position and when the foot section is in the second position.
-
18. A bed, comprising
a plurality of casters, a base supported by the casters, the base having a head end, a foot end spaced from the head end, and an adjustable length, a deck configured to support a mattress, the deck being supported by the base, the deck including a foot section, the foot section being movable from a first position in which the foot section is substantially parallel to the base to a second position in which the foot section is at an angle relative to the base, and a controller configured to change the length of the base if the foot section has moved, a brake coupled to at least one of the casters, wherein the controller is configured to activate the brake after the length of the base is changed.
-
19. A bed, comprising
a plurality of casters, a base supported by the casters, the base having a head end, a foot end spaced from the head end, and an adjustable length, a deck configured to support a mattress, the deck being supported by the base, the deck including a foot section, the foot section being movable from a first position in which the foot section is substantially parallel to the base to a second position in which the foot section is at an angle relative to the base, a controller configured to change the length of the base if the foot section has moved, and a foot end caster supporting the foot end of the base and a brake coupled to the foot end caster, wherein the controller is configured to release the brake before the length of the base is changed.
