Abstract

A hands-free rescue/carrying apparatus includes at least one body-worn garment having a front facing side and a rear facing side, and at least one adjustable lift mechanism attached to the at least one body-worn garment. The at least one lift mechanism is attachable to an article to be supported and is designed to provide a substantial mechanical advantage as to the weight of the article, when employed. Advantageously, the garment having the at least one lift mechanism permits selective dynamic lift capability of the article to which it is attached and secured in a substantially hands-free manner.

Claims

1. An apparatus comprising:

at least a pair of body-worn garments and a supported article, in which each of the body-worn garments has;

a front facing side and a rear facing side; and

at least one adjustable lift mechanism attached to said at least one body-worn garment, said at least one lift mechanism being attachable to an article to be supported by said at least one lift mechanism;

said at least one lift mechanism comprising a first block and a second block axially aligned with one another, each of said first and second blocks comprising at least one pair of pulleys and a cable wound through the pulleys;

wherein the pair of body-worn garments are wearable by at least two persons, each of said body-worn garments including at least one lift mechanism that is attached to said garment and to said supported article, respectively; and

wherein an extending end of the cable extending from said at least one lift mechanism, on each of the body-worn garments, is acted upon to control the vertical movement of said supported article, and said at least one lift mechanism includes a locking mechanism to lock the extending end of said cable in one direction.

2. An apparatus as recited in claim 1, wherein each of said body worn garments is configured such that said supported article can be interchangeably and selectively attachable to either the front facing side or the rear facing side of each of said body worn garments.

3. An apparatus as recited in claim 1, wherein said supported article is a litter.

4. An apparatus as recited in claim 1, wherein said lift mechanism includes carabineers attached to at least one of said first block and said second block to releasably engage at least one of said article and said garment.

5. An apparatus as recited in claim 1, wherein said at least one lift mechanism is configured to be attached to multiple types of articles for lifting and carrying thereof.

6. An apparatus as recited in claim 1, wherein said at least one body worn garment can be adjustably fitted to the wearer thereof.

7. An apparatus as recited in claim 1, wherein said apparatus includes at least one swivel block attached between said lift mechanism to said at least one body-worn garment.

8. An apparatus as recited in claim 7, wherein each of said first block and said second block are rotatably supported about a common axis of said lift mechanism.

9. An apparatus as recited in claim 1, wherein said first block of said at least one lift mechanism is attached to said body-worn garment and the second block of said at least one lift mechanism comprises an attachment component configured to be attachable to said supported article to be lifted by said at least one lift mechanism.

10. An apparatus as recited in claim 9, wherein said lift mechanism is releasably attached to said at least one garment.

11. An apparatus as recited in claim 9, wherein an extending end of said cable is pulled by a wearer of said garment to control the lifting of a connected article, said at least one lift mechanism further including a locking mechanism to lock the position of an extending end of said cable in one axial direction.

12. An apparatus as recited in claim 11, wherein said locking mechanism is selectively releasable to permit vertical adjustment of a supported article while the garment is worn.

13. An apparatus as recited in claim 1, wherein each said locking mechanism is selectively releasable to permit vertical adjustment of a supported article by each individual.

14. An apparatus as recited in claim 13 in which said locking mechanism comprises a cleat.

15. An apparatus as recited in claim 13 in which said locking mechanism comprises a pair of opposing pivotable camming elements.

16. An apparatus as recited in claim 13 in which said apparatus comprises at least two of said adjustable lift mechanisms.

17. An apparatus as recited in claim 1, wherein said supported article comprises a litter frame, and the apparatus includes means for supporting said litter frame against said garment and maintaining a specific vertical height.

18. An apparatus as recited in claim 17, wherein said article supporting means includes at least one hook member extending from a facing side of said garment, the vertical position of said at least one hook member being selectively adjustable.

19. An apparatus as recited in claim 18, wherein said at least one hook member is attached to between horizontal spaced strap members provided on said garment.

20. An apparatus as recited in claim 1, wherein said garment includes at least one pocket.

21. An apparatus as recited in claim 20, wherein at least a portion of said lift mechanism is disposed within said pocket.

22. An apparatus as recited in claim 21 wherein said portion of said lift mechanism includes an extending end of said wound cable.

23. An apparatus as recited in claim 21, wherein said portion of said lift mechanism includes at least one block of said lift mechanism.

24. A dynamic lifting apparatus for supporting an article between at least two persons, said lifting apparatus comprising:

a first garment wearable by a first person;

a second garment wearable by a second person; and

a supported article;

wherein each of said first and second garments includes;

article securing means to permit securement of said supported article to be lifted to each of said garments; and

at least one adjustable lifting mechanism attachable to said first garment and said second garment for lifting and selectively adjusting the relative position of said lifted article, wherein said adjustable lifting mechanism permits the vertical position of said supported article to be selectively and dynamically adjusted while said supported article is being carried between said first and second person without first requiring removal of said garments;

wherein said adjustable lifting mechanism comprises a pair of blocks axially aligned with one another, each of said blocks including a pair of axially defined pulleys, said arrangement forming a block and tackle and a cable wound through and between said blocks, wherein one block of said lift mechanism is attached to said article securing means, wherein an extending end of the cable is acted upon to control the vertical movement of said supported article, and said adjustable lifting mechanism includes a locking mechanism to lock the extending end of said cable in one direction.

25. An apparatus as recited in claim 24, wherein said supported article to be supported is a rescue support member.

26. An apparatus as recited in claim 24, wherein said supported article to be supported is a litter.

27. An apparatus as recited in claim 24, wherein said supported article to be supported is a wheelchair.

28. An apparatus as recited in claim 24, wherein said apparatus is a rescue apparatus.

29. An apparatus comprising:

a first garment, a second garment, and a supported article, in which each of the first and second garments comprises;

at least two lift mechanisms attached to the garment, in which each of the lift mechanisms provides a mechanical advantage and comprises;

a pair of axially disposed blocks, each of said blocks including at least one pulley and a cable wound through the blocks to create a block and tackle arrangement wherein one of said blocks is movable and the other of said blocks is fixed;

said movable block including a first connector to secure to the supported article; and

said fixed block including a second connector and a locking device in which an extending end of said wound cable can be pulled in a first direction and said locking device prevents said end from moving in an opposite second direction, wherein said lift mechanism permits selective dynamic lifting capability of the supported article to which said first connector is attached.

30. A wearable device as recited in claim 29, wherein said first connector permits pivotal attachment to said garment.

31. A wearable device as recited in claim 29, wherein said first connector is attached to a swivel.
