  • Patent number: 9737149
    Abstract: 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.
    Type: Grant
    Filed: September 10, 2010
    Date of Patent: August 22, 2017

  • Patent number: 9173795
    Abstract: A brake system for a patient support apparatus having a base frame includes pedals positioned to be moved by a user to move a brake and a mechanism positioned to coordinate movement of the pedals so that downward movement of one pedal positioned adjacent the head end of the base causes movement of the mechanism in a first direction and downward movement of another of the pedals causes movement of the mechanism in a second direction, opposite the first direction.

  • Patent number: 8104120
    Abstract: 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.
