Abstract

Claims (36)

1. A search line rescue system for use by rescue personnel to facilitate a safe search and rescue mission through an area of possible low visibility, comprising:

a search rope having a first end, a central portion and a second end, the first end configured to be attachable to a fixed point at an entry point, the central portion comprising at least one distance marker;

a search device handle having a leading end and a trailing end, the search device handle being slidably coupled to the search rope, the search device handle comprising:

a rigid body;

an automatic lock mechanism coupled to the rigid body, the automatic lock mechanism comprising a manual lock release; and

at least one tag line attachment anchor; and

at least one locking directional indicator securely coupled to the search rope at a desired location, the locking directional indicator configured to releasably engage with the automatic lock mechanism of the search device handle.

2. The search line rescue system of claim 1 , wherein the search rope is constructed from at least one fire retardant material.

3. The search line rescue system of claim 1 , wherein the search rope further comprises a connector on the second end.

4. The search line rescue system of claim 1 , wherein the central portion of the search rope further comprises a plurality of distance markers securely coupled to the search rope at known spacing therebetween.

5. The search line rescue system of claim 4 , wherein each distance marker has rounded corners and edges.

6. The search line rescue system of claim 4 , wherein the plurality of distance markers are equally spaced along the search rope.

7. The search line rescue system of claim 6 , wherein at least a first one of the plurality of distance markers is of a first shape and at least a second one of the plurality of distance markers is of a second shape.

8. The search line rescue system of claim 1 , wherein the automatic lock mechanism comprises a locking pin coupled to a spring activated member.

9. The search line rescue system of claim 1 , wherein the manual lock release comprises a lever portion extending from the automatic lock mechanism.

10. The search line rescue system of claim 1 , wherein the rigid body of the search device handle is sufficiently sized to allow the distance marker to pass therethrough without interfering with the automatic lock mechanism.

11. The search line rescue system of claim 1 , wherein the rigid body has internal tapers at the leading and trailing ends to facilitate passing through of the locking directional indicator.

12. The search line rescue system of claim 1 , wherein the search device handle further comprises raised edges at the leading and trailing ends to prevent slipping of a firefighter's gloved hand.

13. The search line rescue system of claim 1 , wherein the search device handle further comprises at least two tag line attachment anchor openings on the leading end of the search device handle.

14. The search line rescue system of claim 1 , wherein the rigid body of the search device handle has a longitudinal slot which allows the search device handle to be laterally engaged onto the search rope.

15. The search line rescue system of claim 1 , wherein the rigid body comprises a first and second half which can quickly be removably coupled to each other around the search rope.

16. The search line rescue system of claim 1 , wherein the search device handle, distance markers and locking directional indicator comprise corrosion-resistant materials.

17. The search line rescue system of claim 1 , wherein the locking directional indicator has leading and trailing ends with different tapered geometries.

18. The search line rescue system of claim 1 , wherein a plurality of locking directional indicators are coupled to the search rope at user-defined intervals.

19. A tactical search system for use by firefighters to facilitate a search and rescue mission, comprising:

a handheld search device having a longitudinal bore therethrough;

a search line comprising at least one locking directional indicator, wherein the search line passes through the longitudinal bore of the handheld search device; and

at least one automatic locking mechanism coupled to the handheld search device operable to releasably engage the locking directional indicator, thereby stopping the displacement of the handheld search device along the search line.

20. The tactical search system of claim 19 , wherein the handheld search device comprises at least one attachment point for arterial search lines.

21. The tactical search system of claim 19 , wherein the locking directional indicator has a two-sided asymmetrical shape with one side indicating the direction towards a first end of the search line and the other side indicating the direction toward the second end of the search line.

22. The tactical search system of claim 19 , further comprising a plurality of distance markers securely coupled to the search line at known intervals.

23. A tactical search system, comprising:

a search line;

a plurality of locking directional indicators securely coupled to the search line at predetermined locations;

a handheld grip device displaceably coupled to the search line, the handheld grip device comprising an automatic lock mechanism operable to releasably engage one of the plurality of locking directional indicators; and

a plurality of distance markers securely coupled to the search line at predetermined intervals.
