Abstract
Latching motion transfer arrangements may be used to raise an object up and out of the engagement with the ground or other support surface and to lower the object back onto the ground or other support surface. In one exemplary embodiment, the mechanism is caused to lift and latch by applying force in a first direction, a first time, and is caused to release and lower by applying force in the first direction, a second time.
Claims3
A method of lifting a bed wheel from a support surface comprising:
- moving a drive member of a lift mechanism linearly in a first direction a first time to cause the lift mechanism to engage the support surface and lift the bed wheel off of the support surface;
- latching the lift mechanism at a position where the bed wheel is spaced apart from the support surface by releasing the drive member;
- moving the drive member of the lift mechanism linearly a second time in said first direction causes the lift mechanism to unlatch the lift mechanism;
- and
- allowing the bed wheel to return to the support surface upon movement of the drive member of the lift mechanism in a second direction.
