초록
A bed comprises a main frame, a leg comprising at least one leg member and at least one link, and a stabilizer connecting the leg member to the main frame. At least portions of the main frame, the leg, the link, and the stabilizer form a four bar system for raising and lowering the bed.
대표청구항▼
What is claimed is: 1. A bed comprising: a main frame; a link pivotally attached at an upper end to the main frame; a leg member pivotally attached at an upper end to a lower end of the link; and a stabilizer pivotally attached at an upper end to the main frame and pivotally attached at a lower end
What is claimed is: 1. A bed comprising: a main frame; a link pivotally attached at an upper end to the main frame; a leg member pivotally attached at an upper end to a lower end of the link; and a stabilizer pivotally attached at an upper end to the main frame and pivotally attached at a lower end to the leg member; wherein the link, leg member and stabilizer are configured to move the main frame between a lower position and a raised position relative to a support surface, wherein the link and stabilizer maintain a non-parallel relationship in the lower position, in the raised position, and as the main frame is moved between the lower position and the raised position; and wherein the leg members are configured to support the position of the main frame relative to the support surface in the lower position, in the raised position, and in any position between the lower position and the raised position. 2. The bed of claim 1, wherein the main frame extends in a longitudinal direction and wherein the leg member comprises an upper portion and a lower portion, separated by a bend in the longitudinal direction. 3. The bed of claim 2, wherein the stabilizer is pivotally attached to the upper portion of the leg member. 4. A bed comprising: a main frame having a longitudinal direction; a leg at a head end of the bed and a leg at a foot end of the bed, each leg comprising: a link pivotally attached at an upper end to the main frame, a leg member pivotally attached at an upper end to a lower end of the link, a foot member attached to a lower end of the leg member and configured for contact with a support surface, and a stabilizer pivotally attached at an upper end to the main frame and pivotally attached at a lower end to the leg member; wherein the legs are configured to move the main frame between a lower position and a raised position relative to the support surface, wherein the link and stabilizer maintain a non-parallel relationship in the lower position, in the raised position, and as the main frame is moved between the lower position and the raised position, and wherein the legs are further configured such that the spacing between the foot member at the head end of the bed and the foot member at the foot end of the bed is substantially the same when the main frame is in the lower position and when the main frame is in the raised position. 5. The bed of claim 4, wherein the legs are configured to maintain the position of the main frame relative to the support surface in the lower position, in the raised position, and in any position between the lower position and the raised position. 6. The bed of claim 4, wherein the legs are further configured such that the longitudinal position of the foot member relative to the main frame is substantially the same when the main frame is in the lower position and when the main frame is in the raised position. 7. The bed of claim 6, wherein the legs are configured to maintain the position of the main frame relative to the support surface in the lower position, in the raised position, and in any position between the lower position and the raised position. 8. A bed comprising: a main frame having a longitudinal direction; a leg comprising a link pivotally attached at an upper end to the main frame, a leg member pivotally attached at an upper end to a lower end of the link, a foot member attached to a lower end of the leg member and configured for contact with a support surface, and a stabilizer pivotally attached at an upper end to the main frame and pivotally attached at a lower end to the leg member; wherein the leg is configured to move the main frame between a lower position and a raised position relative to the support surface, wherein the link and stabilizer maintain a non-parallel relationship in the lower position, in the raised position, and as the main frame is moved between the lower position and the raised position, and wherein the leg is further configured such that the longitudinal position of the foot member relative to the main frame is substantially the same when the main frame is in the lower position and when the main frame is in the raised position. 9. The bed of claim 8, wherein the leg is configured to maintain the position of the main frame relative to the support surface in the lower position, in the raised position, and in any position between the lower position and the raised position. 10. The bed of claim 8, wherein the leg is located at a head end of the bed, further comprising a leg located at a foot end of the bed, wherein the legs are configured such that the spacing between the foot member at the head end of the bed and the foot member at the foot end of the bed is substantially the same when the main frame is in the lower position and when the main frame is in the raised position. 11. The bed of claim 10, wherein the legs are configured to maintain the position of the main frame relative to the support surface in the lower position, in the raised position, and in any position between the lower position and the raised position.
