Abstract
A lifting support device that includes a linear actuator including a first end configured to support an object, and a load sensor positioned to determine application of a first load on the load sensor by at least the object. The linear actuator is maintained in equilibrium when supporting the first load. The lifting support device further includes a controller coupled in communication with the load sensor, and the controller is configured to selectively actuate the linear actuator in response to application of a second load on the load sensor.
Claims8
A lifting support device comprising:
- a linear actuator comprising a first end configured to support an object, and a second end opposite the first end to define a length of said linear actuator therebetween, and to define a height at which the object is lifted relative to the ground;
- a load sensor positioned to determine application of a first load on said load sensor by at least the object, wherein said linear actuator is maintained in equilibrium when supporting the first load;
- and
- a controller coupled in communication with said load sensor, said controller configured to selectively actuate said linear actuator in response to application of a second load on said load sensor, and configured to return said linear actuator to said equilibrium after the second load is removed, the controller configured to extend the linear actuator to increase the height of the object relative to the ground when the second load is a negative load, and the controller configured to retract the linear actuator to decrease the height of the object relative to the ground when the second load is a positive load.
