Abstract

A multiple-rope or multiple-cable pulling device is provided for positioning a load. The device can include an electronic controller that interprets a user'"'"'s input from an interface such as a trigger or a joystick, and activates electronically controlled motors that drive one or more rope pulling mechanisms, such as winches. When the winches pull in or pay out cable in accordance with the controller'"'"'s demand, the load is moved along the desired trajectory as specified by the user through the device interface.

Claims

1. A device for positioning a load suspended by cables, comprising:

a plurality of powered rotational motors having outputs;

a plurality of cable pulling mechanisms, each coupled to its own powered rotational motor output;

a user interface that allows a user to control said device in order to move the load along a desired trajectory in at least 2 dimensions;

whereby when the user controls the device via the user interface, the powered rotational motors activate the cable pulling mechanisms, which then pull in or pay out the cables by which the load is suspended, thereby moving the load along the desired trajectory.

2. The device of claim 1, further comprising a means for powering the rotational motor.

3. The device of claim 2, wherein the means for powering the rotational motor includes a plurality of rechargeable batteries.

4. The device of claim 1, further comprising a means for interpreting the user input and computing requisite cable feed velocities to accomplish the desired movement

5. The device of claim 1, wherein the powered rotational motors are DC electric motors

6. The device of claim 1, wherein each of the cable pulling mechanisms are connected to the outputs of their rotational motors by a gearbox.

7. The device of claim 1, wherein the guide mechanism includes one or more clip elements and is configured to attach to the resilient elongate element without threading an end of the resilient elongate element through the device.

8. The device of claim 1, further comprising a resilient elongate element engaged with the guide mechanism and the rope pulling mechanism.

9. The device of claim 8, further comprising an object having a weight attached to either the resilient element or the device for movement of the object by pulling on the resilient elongate element by the device.

10. The device of claim 9, wherein the object is a person and the person is attached to the device.

11. The device of claim 1, wherein the device is configured to be a portable hand-held device.

12. The device of claim 1, wherein the device is configured to be a multi-dimensional hoist.
