Engagement article, load positioning system, and process for positioning loads
View Patent ↗An engagement article is provided that is capable of selectively restricting movement or securing a suspended load in response to a rapid change in tension in one or more lines.
1. An engagement article capable of selectively restricting movement or securing a suspended load in response to a rapid change in tension in one or more lines, comprising:
a travel positioning mechanism operatively connectable to a carriage and at least one travel line, the travel positioning mechanism capable of positioning the carriage at intermediate positions along the travel line; and
the carriage operatively connectable to the at least one travel line and at least one lift line for supporting a load, the carriage operatively connectable to a first end and a second end of the travel line.
2. The engagement article of claim 1 , comprising a lift positioning mechanism operatively connectable to the carriage.
3. The engagement article of claim 1 , comprising
a lift positioning mechanism operably connectable to a carriage; and
the carriage operably connectable to at least one travel line and at least one lift line for supporting a load.
4. The engagement article of claim 2 , wherein at least one of the travel positioning mechanism and the lift positioning mechanism is a manual device.
5. The engagement article of claim 2 , wherein the lift positioning mechanism is operatively connectable to a first end of the lift line and the second end of the lift line is operatively connectable to the load.
6. The engagement article of claim 1 , wherein the travel positioning mechanism includes an airflow interaction feature.
7. The engagement article of claim 1 , wherein the travel positioning mechanism includes a weighted member and a cam engagement member pivotally connected eccentrically with respect to the center of gravity of the cam engagement member.
8. The engagement article of claim 7 , wherein the travel positioning mechanism includes an airflow interaction feature formed in at least one of the weighted member and the cam engagement member.
9. The engagement article of claim 1 , comprising
a first travel positioning mechanism operably connectable to a carriage, the first travel positioning mechanism operatively connectable to at least one travel line; and
a second travel positioning mechanism operatively connectable to at least one travel line, the second travel positioning mechanism positioned opposite the first travel positioning mechanism;
wherein the carriage is operatively connectable to at least one lift line for supporting a load.
10. The engagement article of claim 1 , comprising
a first travel positioning mechanism operatively connectable to a carriage, the first travel positioning mechanism operatively connectable to at least one travel line;
a second travel positioning mechanism operatively connectable to at least one travel line, the second travel positioning mechanism positioned opposite the first travel positioning mechanism; and
wherein the carriage is operatively connectable to at least one travel line.
11. The engagement article of claim 10 , wherein at least one of the first travel positioning mechanism and second travel positioning mechanism includes an airflow interaction feature.
12. The engagement article of claim 1 , comprising
a travel positioning mechanism operatively connectable to a carriage, the travel positioning mechanism operatively connectable at a first connection to at least one travel line;
the travel positioning mechanism operatively connectable at a second connection to at least one travel line, the second connection positioned opposite the first connection;
the carriage operatively connectable to at least one lift line for supporting a load; and
wherein the travel positioning mechanism having an airflow interaction feature.
13. A system comprising an engagement article capable of selectively restricting movement or securing a suspended load in response to a rapid change in tension in one or more lines, the system further comprising:
a carriage operatively connectable to at least one lift line for supporting a load;
the engagement article comprising a travel positioning mechanism operatively connectable at a first connection to at least one travel line;
the travel positioning mechanism operatively connectable at a second connection to at least one travel line, the second connection positioned opposite the first connection; and
wherein the travel positioning mechanism having an airflow interaction feature.
14. A process of selectively restricting movement or securing a suspended load comprising:
providing an engagement article in response to a rapid change in tension in one or more lines,
wherein the engagement article is a travel positioning mechanism operatively connectable to a carriage and a travel line, the carriage operatively connectable to at least one lift line for supporting a load and the travel line,
wherein the engagement article comprises a lift positioning mechanism operatively connectable to the carriage,
wherein at least one of the travel positioning mechanism and the lift positioning mechanism includes an airflow interaction feature; and
actuating the engagement article.
