A bed includes a base frame 14 having a head end and a foot end, an elevatable frame 16 also having a head end and a foot end, a lift assembly 76 or 78 comprising an actuation system connected to one of the frames, a push chain 106 having an actuator end 124 driven by a lead screw 86 and a distal end 126 connected to the other of the frames. Rotary motion of the lead screw changes elevation of the elevating frame relative to the base frame.

A patient-support apparatus has a frame including a pair of laterally spaced apart first and second rails and a set of cross members interconnecting the first and second rails. The first and second rails each terminate near a head end and a foot end of the patient-support apparatus. A patient support platform includes at least one pivotable deck section and is carried by the frame. A cable conduit is coupled to the set of cross members and extends parallel with the first and second rails. The cable conduit supports a plurality of electrical cables that extend between the head end and foot end of the patient-support apparatus.

A patient-support apparatus includes a patient-support deck having a head deck section, seat deck section, and foot deck section each of which is supported on a frame. The head deck section pivots and translates relative to the frame when driven. The drive systems of the deck sections are configured such that movement of links driving the deck sections occurs above the lowest point on the frame.

A bed 14 has a base frame 32, an elevateable frame 34 and a telescopable column 36 having a base segment 36a connected to the base frame 32 and a terminal segment 36e connected to the elevateable frame 34. Each column circumscribes a lift chain assembly 100 which includes a magazine 102 and a lift chain 160 with a terminal link 240. The magazine 102 is connected to either the base frame 32 or the elevateable frame 34 and the terminal link 240 is connected to the other of the base frame 32 and the elevateable frame 34. The magazine 102 comprises left and right magazine covers 104, 106 each having an outer face and an inner face 112, 114 with grooves 120. The lift chain 160 has left and right rollers 238 that project into the grooves. The lift chain assembly 100 also includes a gear train 320 extending from a gear train drive shaft 334 to a gear train output shaft 338 and a motor 278 having an output shaft 314 connected to the gear train drive shaft 334.

A patient support apparatus, such as a hospital bed, comprises a lower frame, an upper frame supported above the lower frame and configured to support a patient, and a support structure coupled to the lower frame. The support structure includes a lift having a movable portion that is movable generally vertically relative to the lower frame and relative to the upper frame. The movable portion of the lift is configured to carry a patient care equipment support.
摘要:
A patient support is provided comprising a support surface, a base, and a lift assembly positioned to support the support surface above the base. The lift assembly includes an actuator configured to adjust the height of the support surface. The actuator includes a housing formed to include first and second cylinders. The actuator further includes a first piston positioned in the first cylinder and a second piston positioned in the second cylinder. The first piston includes a first fluid passage therein. The second piston includes a second fluid passage therein.

A height adjustable bed framework 12 includes a base frame 24, an elevatable frame 30, a lift chain 50 and a power module 52. The lift chain is connected to the base frame or the elevatable frame and the power module is connected to the other frame. The power module includes an energy converter such as an electric motor 90, a planetary gear train 110 driven by the energy converter and a chain driver, such as a sprocket 160, engaged with the lift chain and driven by the planetary gear train.
