Abstract

A stop device for holding a unit load device in place on decking is described. In one example, the stop device includes a switchable magnet with an actuator to engage or disengage the stop device on decking using a switchable magnetic field of the stop device. The stop device also includes an interface bumper secured over a first surface of the switchable magnet, a foot plate secured over a second surface of the switchable magnet, and a handle rod assembly that extends from the switchable magnet for positioning the switchable magnet on the decking. The handle rod assembly includes a switch linkage, with the switch linkage extending from the actuator of the switchable magnet to a distal end of the handle rod assembly with a handle for a user. An individual can rotate a locking lever of the stop device to engage or disengage the stop device on the decking.

First claim

Therefore, the following is claimed:

1. A system for interfering with movement of a unit load device on decking, comprising:
an area of decking for supporting the unit load device; and
a stop device for holding the unit load device in place at a location on the decking, the stop device comprising:
a switchable magnet comprising an actuator;
an interface bumper secured over a first surface of the switchable magnet;
a foot plate secured over a second surface of the switchable magnet; and
a handle rod assembly that extends from the switchable magnet for positioning the switchable magnet on the decking.

2. The system according to claim 1 , wherein the handle rod assembly comprises:
a coupling, the switchable magnet being secured with the coupling;
a rod secured to the coupling at a first end of the rod; and
a handle secured to the rod at a second end of the rod.

3. The system according to claim 2 , wherein the handle rod assembly further comprises:
a switch linkage, the switch linkage extending from the actuator of the switchable magnet to the second end of the rod; and
a locking lever to rotate the switch linkage and the actuator of the switchable magnet.

4. The system according to claim 3 , wherein the interface bumper comprises a corner notch to seat a corner edge of the unit load device.

5. A stop device for interfering with movement of a unit load device on decking, comprising:
a switchable magnet comprising an actuator;
an interface bumper secured over a side surface of the switchable magnet; and
a handle rod assembly that extends from the switchable magnet for positioning the switchable magnet on the decking.

6. The stop device according to claim 5 , wherein:
the switchable magnet provides a magnetic field for engaging the stop device with the decking in a first position of the actuator; and
the switchable magnet impedes the magnetic field for releasing the stop device from the decking in a second position of the actuator.

7. The stop device according to claim 5 , wherein the handle rod assembly comprises:
a coupling, the switchable magnet being secured with the coupling;
a rod secured to the coupling at a first end of the rod; and
a handle secured to the rod at a second end of the rod.

8. The stop device according to claim 7 , wherein the handle rod assembly further comprises a switch linkage, the switch linkage extending from the actuator of the switchable magnet to the second end of the rod.

9. The stop device according to claim 8 , wherein the handle rod assembly further comprises a locking lever to rotate the switch linkage and the actuator of the switchable magnet.

10. The stop device according to claim 9 , wherein:
the locking lever comprises a locking detent; and
the handle rod assembly further comprises a locking peg on the rod, wherein the locking lever is configured to interlink the locking detent over the locking peg by folding the locking lever to extend parallel to the rod.

11. The stop device according to claim 5 , further comprising:
a first foot plate secured over a second side surface of the switchable magnet; and
a second foot plate secured over a third side surface of the switchable magnet, wherein the third side surface faces away from the second side surface.

12. The stop device according to claim 5 , wherein the interface bumper comprises:
an angled top surface to deflect force from an edge of the unit load device toward a surface of the decking; and
a corner notch to seat a corner edge of the unit load device.

13. The stop device according to claim 5 , further comprising a friction pad over a bottom surface of the switchable magnet.

14. A method for interfering with movement of a unit load device on decking, comprising:
positioning a stop device at a position over the decking; and
engaging a switchable magnet of the stop device with the decking, wherein the stop device comprises:
the switchable magnet;
an interface bumper secured over a side surface of the switchable magnet; and
a handle rod assembly that extends from the switchable magnet for positioning the switchable magnet on the decking.

15. The method according to claim 14 , wherein engaging the switchable magnet to the decking comprises rotating a locking lever of the handle rod assembly and an actuator of the switchable magnet.

16. The method according to claim 15 , wherein:
the locking lever comprises a locking detent; and
the handle rod assembly further comprises a locking peg on the rod, wherein the locking lever is configured to interlink the locking detent over the locking peg by folding the locking lever to extend parallel to the rod.

17. The method according to claim 15 , further comprising releasing the switchable magnet from the decking.

18. The method according to claim 17 , wherein releasing the switchable magnet from the decking comprises rotating a locking lever of the handle rod assembly and an actuator of the switchable magnet.

19. The method according to claim 15 , wherein the interface bumper comprises an angled surface to deflect force from an edge of the unit load device toward a surface of the decking.

20. The method according to claim 15 , wherein the stop device further comprises a friction pad over a bottom surface of the switchable magnet.
