Abstract
A lifting mechanism for a bed includes an elongate first leg having a first leg axis; an elongate second leg having a second leg axis and being pivotally connected to the first leg; a carriage assembly slidably connected to the first leg so as to be moveable in a direction substantially parallel to the first leg axis; a guide rail connected to the second leg and having a guide rail axis, the guide rail axis being at a non-zero angle to the second leg axis; and a moveable actuator configured to apply a force to the carriage assembly.
Claims20
A lifting mechanism for a bed comprising:
- an elongate first leg having a first leg axis;
- an elongate second leg having a second leg axis and being pivotally connected to the first leg;
- a carriage assembly slidably connected to the first leg so as to be moveable in a direction substantially parallel to the first leg axis;
- a guide rail connected to the second leg and having a guide rail axis, the guide rail axis being at a non-zero angle to the second leg axis;
- and
- a moveable actuator configured to apply a force to the carriage assembly,
- wherein, during a first range of movement of the actuator the carriage assembly moves relative to the first leg and the carriage assembly is engaged with the guide rail to apply a force to the guide rail, and during a second range of movement of the actuator the carriage assembly is disengaged from the guide rail and engages with the first leg, and wherein movement of the actuator causes movement of the first leg relative to the second leg about the pivotal connection.

A bed comprising:
- a support frame for supporting a mattress;
- and
- a lifting mechanism comprising:
- an elongate first leg having a first leg axis, an end of the first leg being pivotally connected to the support frame;
- an elongate second leg having a second leg axis and being pivotally connected to the first leg, and an end of the second leg being pivotally connected to the support frame;
- a carriage assembly slidably connected to the first leg so as to be moveable in a direction substantially parallel to the first leg axis;
- a guide rail connected to the second leg and having a guide rail axis, the guide rail axis being at a non-zero angle to the second leg axis;
- and
- a moveable actuator configured to apply a force to the carriage assembly,
- wherein, during a first part of said movement of the actuator the carriage assembly moves relative to the first leg and the carriage assembly is engaged with the guide rail to apply a force to the guide rail, and during a second part of said movement of the actuator the carriage assembly is disengaged from the guide rail and engages with the first leg, and wherein said movement of the actuator causes movement of the first leg relative to the second leg about the pivotal connection so as to raise and lower the support frame.
