Abstract

A method and apparatus to regulate the use and removal of freight. The apparatus includes a sensing element, a stoppage element, and at least one actuator. The sensing element is operable to determine the presence of freight. Stoppage element can alternate between a first condition configured to impede freight removal and a second condition configured to permit freight removal. The presence of freight maintains stoppage element in the first condition absent engagement of the at least one actuator and engagement of the at least one actuator switches stoppage element to the second condition when freight is present.

First claim

What is claimed is:

1. A freight removal regulation apparatus, comprising:
a sensing element operable to determine a presence of freight;
a stoppage element operable to alternate between a first condition configured to impede freight removal and a second condition configured to permit freight removal;
an actuator; and
a warning element configured to alternate between a first state allowing user access and a second state warning against user access,
wherein the presence of freight maintains the stoppage element in the first condition and maintains the warning element in the first state, absent engagement of the actuator; and
wherein engagement of the actuator switches the stoppage element to the second condition and switches the warning element to the second state, when freight is present.

2. The apparatus as recited in claim 1 , wherein the stoppage element comprises a blocking member, the blocking member configured to obstruct one or more lift access means on freight when in the first condition and to reveal one or more lift access means on freight when in the second condition.

3. The apparatus as recited in claim 2 , wherein the one or more lift access means on freight comprises one or more fork engagement ports.

4. The apparatus as recited in claim 1 , wherein the actuator is a mechanical actuator.

5. The apparatus as recited in claim 1 , wherein the actuator is a foot pedal.

6. The apparatus as recited in claim 1 , wherein the presence of freight switches the stoppage element from the second condition to the first condition.

7. The apparatus as recited in claim 1 , wherein the warning element comprises a sign and alternation of the warning element between the first and second states involves mechanical movement of the sign.

8. The apparatus as recited in claim 1 , wherein the presence of freight switches the warning element from the second condition to the first condition.

9. The apparatus as recited in claim 1 , wherein the stoppage element and the warning element are disposed on opposing sides of the apparatus.

10. The apparatus as recited in claim 9 , wherein the actuator is disposed on the side of the apparatus having the warning element.

11. A method to improve freight use, comprising:
placing freight in position with respect to a sensing element, the placement of freight in position causing:
a stoppage element to be present in a first condition, the first condition configured to impede freight removal; and
a warning element to be present in a first state, the first state configured to allow user access; and

engaging an actuator to:
switch the stoppage element to a second condition, the second condition configured to permit freight removal; and
switch the warning element to a second state, the second state configured to warn against user access.

12. The method as recited in claim 11 , wherein the stoppage element comprises a blocking member, the blocking member configured to obstruct one or more lift access means on freight when in the first condition and to reveal one or more lift access means on freight when in the second condition.

13. The method as recited in claim 12 , wherein the one or more lift access means comprise one or more fork engagement ports.

14. The method as recited in claim 11 , wherein the actuator is a mechanical actuator.

15. The method as recited in claim 11 , wherein the actuator is a foot pedal.

16. The method as recited in claim 11 , wherein the warning element comprises a sign and wherein switching the warning element between the first state and second state involves mechanical movement of the sign.
