摘要：
An adjustable height bed (100). The adjustable height bed (100) includes a deck (103) connected to a bed frame (102) and one or more leg assemblies (104). In some embodiments, the one or more leg assemblies (104) are connected to the bed frame (102) and articulate to adjust the height of the bed frame (102) relative to a floor. A leg assembly (104), in one embodiment, includes a leg (106) and a leg slide (114). The leg slide (114) may be configured to translate in a substantially linear path relative to the bed frame (102). The leg slide (114) articulates relative to the bed frame (102) at a linear bearing (124) in some embodiments. In one embodiment, the leg slide (114) articulates relative to the leg (106) at a rotational bearing (116) positioned below the linear bearing (124).

CLAIMS
1. An adjustable height bed comprising:
a bed frame;
one or more leg assemblies connected to the bed frame wherein the one or more leg assemblies articulate to adjust the height of the bed frame relative to a floor, a leg assembly of the one or more leg assemblies comprising:
a leg; and
a leg slide configured to translate in a substantially linear path relative to the bed frame wherein the leg slide articulates relative to the bed frame at a linear bearing and the leg slide articulates relative to the leg at a rotational bearing positioned below the linear bearing.
2. The adjustable height bed of claim 1, further comprising:
a leg support rotatably connected to the leg at a support rotation axis and rotatably connected to the bed frame at an upper fixed pivot point; and
a wheel assembly rotatably connected to the leg at a wheel assembly rotation axis;
wherein:
the leg is attached to the leg slide at a leg rotation axis;
the leg rotation axis, the support rotation axis, and the wheel assembly axis are substantially parallel;
the leg rotation axis, the support rotation axis, and the wheel assembly axis, when viewed along their length, form three points that are substantially co-linear.
3. The adjustable height bed of claim 2, wherein the linear bearing and the leg rotation axis are separated by a predetermined, non-zero distance.
4. The adjustable height bed of claim 3, wherein translation of the linear bearing is restricted to a predetermined translation range.
5. The adjustable height bed of claim 4, wherein:
translation of the linear bearing is restricted to a minimum allowed distance from the upper fixed pivot point at which the bed frame is in a highest allowed position;
translation of the linear bearing is restricted to a maximum allowed distance from the upper fixed pivot point at which the bed frame is in a lowest allowed position.
6. The adjustable height bed of claim 5, wherein translation of the linear bearing is restricted by one or more mechanical stops.
7. The adjustable height bed of claim 5 further comprising:
one or more sensors to determine a position of the linear bearing;
an electronic control to receive an input from the one or more sensors and restrict movement of the linear bearing in response to the linear bearing reaching a predetermined position.
8. An adjustable height bed comprising:
a bed frame;
one or more leg assemblies connected to the bed frame, wherein the one or more leg assemblies articulate to adjust the height of the bed frame relative to a floor, a leg assembly of the one or more leg assemblies comprising:
a leg; and
a leg slide configured to translate in a substantially linear path relative to the bed frame;
wherein the leg slide articulates relative to the bed frame at a linear bearing and the leg slide articulates relative to the leg at a rotational bearing positioned the at a predetermined, non-zero distance from the linear bearing.
9. The adjustable height bed of claim 8, wherein the linear bearing is disposed substantially inside of a bed frame element of the bed frame.
10. The adjustable height bed of claim 9 wherein the linear bearing has a profile shaped to conform to an interior of the bed frame element.
11. The adjustable height bed of claim 9 wherein the bed frame element comprises a slot through which a portion of the leg slide is disposed. 12. The adjustable height bed of claim 11 , wherein the slot includes a maximum height stop and a minimum height stop.
13. The adjustable height bed of claim 8, wherein the adjustable height bed includes a channel, and the linear bearing interfaces with the channel.
14. The adjustable height bed of claim 13, wherein the channel is selected from the group consisting of a box channel and a C channel.
15. The adjustable height bed of claim 13, wherein the channel includes a maximum height stop and a minimum height stop.
16. The adjustable height bed of claim 8, wherein the linear bearing comprises a slider block.
17. The adjustable height bed of claim 8, wherein the linear bearing comprises one or more rotating elements.
18. An adjustable height bed comprising:
a bed frame;
one or more leg assemblies connected to the bed frame, wherein the one or more leg assemblies articulate to adjust the height of the bed frame relative to a floor, a leg assembly of the one or more leg assemblies comprising:
a leg; and
a leg slide configured to translate in a substantially linear path relative to the bed frame, wherein the leg slide articulates relative to the bed frame at a linear bearing and the leg slide articulates relative to the leg at a rotational bearing positioned below the linear bearing;
a leg support rotatably connected to the leg at a support rotation axis and rotatably connected to the bed frame at an upper fixed pivot point; and
a wheel assembly rotatably connected to the leg at a wheel assembly rotation axis;
wherein:
the leg is attached to the leg slide at a leg rotation axis;
the leg rotation axis, the support rotation axis, and the wheel assembly axis are substantially parallel;
the leg rotation axis, the support rotation axis, and the wheel assembly axis, when viewed along their length, form three points that are substantially co-linear.
19. The adjustable height bed of claim 18, further comprising a maximum height stop configured to restrict movement of the linear bearing toward the upper fixed pivot point.
20. The adjustable height bed of claim 18, further comprising a minimum height stop configured to restrict movement of the linear bearing away from the upper fixed pivot point.
