Abstract

A swift water rescue sled and a method for rescuing an individual who has fallen into swift moving water. A stationary steering line is attached to the bottom of the rescue sled between the opposite sides thereof. An anchor line runs in a first direction along the top of the sled and then in an opposite direction along the bottom at which the anchor line bends around an anchor line pulley. From the anchor line pulley, the anchor line turns around and runs in the first direction along the bottom of the sled and outwardly from the front to be tied to an anchor. A steering line pulley rides over the stationary steering line. The anchor line and steering line pulleys are coupled to one another at the bottom of the rescue sled. The rescue sled is steered towards the individual in response to the operator shifting his weight.

Description

SWIFT WATER RESCUE SLED AND METHOD

BACKGROUND OF THE INVENTION

[0001] 1. Technical Field

This invention relates to a lightweight, easy to transport swift water rescue sled that has particular application for rescuing an individual who has fallen into and is being pulled downstream by swift moving water. The rescue sled includes anchor and steering lines (e.g., multi-strand ropes) that are coupled to one another underneath the sled at approximately midway along its length to permit the sled to be accurately steered towards an individual to be rescued in response to the sled operator shifting his weight from side-to-side.

[0002] 2. Background Art

Individuals are known to accidentally fall into swiftly moving water such as that found in a river, aqueduct, spillway flood control channel, or the like. A common rescue attempt involves throwing a rope or a floatation device to the individual hoping to be rescued. However, because the individual is often moving rapidly in the water, he may miss catching the rope or floatation device entirely. This leaves the rescuers having to catch up to the individual if they wish to try another rescue attempt Moreover, such a rescue attempt requires that the individual to be rescued, who is often exhausted and perhaps injured, have the strength and ability to grab and hold onto the device that is thrown to him.

[0003] Helicopters have also been used to fly overhead and dangle a rope above the individual. Once again, the individual must be able to catch and hold onto the rope. What is more, the use of a helicopter to affect a rescue can be expensive, and a helicopter is not always readily available to come to the aid of the individual in the short time within which to complete the rescue.

[0004] Inflatable boats are known to be dropped in the water to try and catch the individual rushing towards it An anchor line is typically tied between land and the front (e.g., nose) of the boat. Because the swiftly moving water usually moves with great force against the front of the boat to which the anchor line is tied, it is sometimes difficult to accurately steer and maneuver the boat against the power of the water to get close enough to the individual so that he can be grabbed and pulled aboard. Missing the oncoming individual may not leave enough time or opportunity to redeploy the boat to make another rescue attempt.

[0005] Therefore, what would be desirable is a relatively low cost, simple to deploy and easy to transport rescue sled that can be accurately steered and maneuvered towards an individual being pulled by swiftly moving and powerful water without requiring that the individual participate in his own rescue by having to grab, hold onto or pull a rescue device. SUMMARY OF THE INVENTION

[0006] In general terms, disclosed herein is a swift water rescue sled and a method for steering the sled to rescue an individual who has fallen into and is being pulled downstream by swift moving water. By virtue of the rescue sled herein disclosed, the rescue may be accomplished without the requirement that the individual actively participate in the process by having to grab, hold onto or pull a rescue device. The rescue sled has a compact size and light weight to be easily transported in the back of a pickup truck or the like.

[0007] The rescue sled includes a buoyant body that is manufactured, for example, from closed cell high density foam so as to be capable of floating in water. A supply of anchor line

(e.g., high strength multi-strand rope) is dispensed from a conventional fishing reel that is bolted to the top of the sled. The anchor line runs continuously, first in a forward direction along the top of the sled, then around a line guide affixed to the nose of the sled where it turns back and extends rearwardly along the bottom of the sled to an anchor line pulley, at which point the anchor line turns around and once again runs in a forward direction along the bottom. The free end of the anchor line extends past the nose to be tied to an anchor that is implanted in the ground adjacent the water in which the rescue line will be deployed.

[0008] A stationary steering line runs laterally across the bottom of the rescue sled at approximately midway along its length. A steering line pulley that is shackled to the anchor line pulley underneath the sled is positioned to ride over the steering line. In order to accurately steer the rescue sled towards an oncoming individual being carried downstream by the rushing water, the sled operator simply shifts his weight to one side or the other. The steering line pulley will correspondingly ride from side-to-side along the steering line depending upon the direction in which the operator shifts his weight. The anchor line pulley and the anchor line that is tied to the land-based anchor move with the steering line pulley relative to the stationary steering line to enable the rescue sled to be maneuvered alongside the individual seeking rescue. The anchor line is controllably let out from the fishing reel until the individual and the rescue sled are traveling in the water at the same speed. Accordingly, the speed and power of the water will now be neutralized to enable the operator of the rescue sled to come alongside and pull the individual onboard and thereby complete the rescue.

DESCRIPTION OF THE PREFERRED EMBODIMENT

[0018] Referring initially to FIGs. 1-7 of the drawings, there is shown a rescue sled 1 that has particular application for rescuing individuals who have fallen into and are being pulled downstream by swift moving water and/or waves common to a river, aqueduct, spillway and flood control channel. However, the rescue sled 1 of this invention is also capable of rescuing individuals and animals trapped in ice. The rescue sled 1 is lightweight and has a compact size so as to be easily transported to the rescue site in the back of a pickup truck or the like. In this regard, to be able to achieve accurate steering, the rescue sled is sized to accommodate the upper half of the operator's body, while his legs dangle in the water.

[0019] The rescue sled 1 has a flat body 3 that is adapted to float in water or slide over ice.

An initially rolled up supply of high strength rope or line 5 is carried by the rescue sled 1 to be dispensed during a rescue and attached to an anchor that is implanted in the ground adjacent the waterway. By way of example, the anchor line 5 is ideally a 12 strand, 3/16 inch thick polyethylene fiber rope. By way of further example, the supply of anchor line 5 can be rolled up on a conventional fishing reel such as that manufactured by Accurate Grinding & Manufacturing

Corporation of Corona, California. The fishing reel 7 is affixed (e.g., bolted) to the top of the body 3 of sled 1. The fishing reel 7 has a usual handle 9 to which a rotational force is manually applied at those times when the rolled up line 5 that has been dispensed must be rewound and rolled back up. [0020] As is best shown in FIGs. 2 and 3, the buoyant body 3 of the rescue sled 1 is preferably manufactured from a closed cell high density foam such as that manufactured by High

Surf Accessories of Maui, Hawaii. A longitudinally extending structurally reinforcing (e.g., fiberglass) mounting plate 12 runs along the top of the foam body 3 to establish a foundation at which the fishing reel 7 is affixed to the sled 1. The nose at the front of the sled 1 is surrounded by a generally C-shaped line guide 14 that covers the front of the sled body 3 and the mounting plate 12 that lies on the top of the sled body 3. The line guide 14 is held in place against the nose of sled 1 by means of a pair of mounting bolts 16 (best shown in FIGs. 2 and 3) that extend completely through line guide 14, the front of the mounting plate 12 that is covered by the line guide, and the sled body 3.

[0021] The anchor line 5 is dispensed from the rolled up supply thereof (i.e., fishing reel 7) so as to run over and around the C-shaped line guide 14. To this end, an upstanding line containment wall 18 (also best shown in FIGs. 2 and 3) is located at each of the opposite sides of the line guide 14 to prevent the line 5 from sliding off the guide as the line moves from side-to- side during a rescue. A coupling window 20 is formed through each line containment wall 18 of the line guide 14.

[0022] An end cap 24 is detachably connected over the line guide 14 at the nose of the rescue sled 1. The end cap 24 includes a pair of snap-on couplers (e.g., clips) 26 which are removably received by respective coupling windows 20 formed in the upstanding line containment walls 18 of the line guide 14 by which the end cap 24 is detachably connected over the line guide. The end cap 24 is preferably manufactured from an impact resistant material so as to function as a front bumper for the rescue sled 1 to push aside debris encountered in the waterway during the rescue.

[0023] As is best shown in FIG. 1, the rolled up supply of anchor line 5 being dispensed from the fishing reel 7 first extends in a forward direction towards the nose of the rescue sled 1 so as to run along the top of the sled body 3, over and around the line guide 14, and below the end cap

(i.e., bumper) 24. The anchor line 5 then turns backs upon itself to run in an opposite rearward direction along the bottom of the sled body towards a pair of pulleys 28 and 30 that are coupled one to the other below the sled body 3.

[0024] More particularly, and as an important feature of this invention, the anchor line 5 bends around an anchor line pulley 28 and reverses its direction to once again run in the forward direction towards the nose of the rescue sled 1. The anchor line 5 runs along the bottom of the sled body 3 (best shown in FIG. 5) in the forward direction until it extends outwardly therefrom ahead of the end cap 24 at the nose of the sled 1. The free end of the anchor line 5 is tied to one end of an optional resilient shock absorber 32. The opposite end of the shock absorber 32 is adapted to be coupled to a stationary anchor (designated 50 in FIG. 8) that is implanted in the ground alongside the waterway in which the rescue sled will be deployed to accomplish the rescue. The optional shock absorber 32 can be eliminated such that the free end of the anchor line 5 at the front of the sled 1 is tied directly to the anchor 50. [0025] A stationary steering line 34 runs laterally across the bottom of the body 3 of the rescue sled 1 at approximately midway along the length thereof. The steering and anchor lines 5 and 34 can be identical ropes as that described above. As is best shown in FIG. 6, the steering line 34 is anchored to the bottom of the rescue sled 1 at opposite sides of the body 3 by means of mounting bolts 36. Similar to the previously described longitudinally extending mounting plate

12, a laterally extending mounting plate 38 (best shown in FIGs. 4 and 6) is located atop the foam core 10 of the sled body 3. The mounting plate 38 runs from side-to-side and across the top of the sled body 3 to establish a structurally reinforcing foundation at which the steering line mounting bolts 36 are affixed to the sled 1. The laterally extending mounting plate 38 intersects the longitudinally extending mounting plate 12 to establish a 3 -point mount within which to receive three pairs of supply line mounting bolts 39 by which to affix the fishing reel 7 to the top of the sled body 3.

[0026] The stationary steering line 34 runs over a steering line pulley 30 that is adapted to ride back and forth (i.e., from side-to-side) along the steering line and across the bottom of the body 3 of the rescue sled 1 as the operator of the sled shifts his weight from side-to-side. By virtue of the foregoing, the operator can maneuver the rescue sled 1 towards the individual in need of rescue by means of a single line steering system and by simply leaning to one side of the body 3 and shifting his weight.

[0027] FIG. 7 shows the anchor line pulley 28 and the steering line pulley 30 coupled to one another at the bottom of the rescue sled 1 behind the nose. Each pulley 28 and 30 has a C- shaped shackle 40 and 42 that are coupled together one inside the other so that the steering line pulley 30 is pulled towards the anchor line pulley 28 while riding on the steering line 34. Thus, as the sled operator shifts his weight to one side and then the other and the steering line pulley 30 correspondingly rides from side-to-side over the stationary steering line 34, the anchor line pulley 28 and the anchor line 5 extending therearound are pulled with one another by the steering line pulley 30 so that both the anchor line 5 and the anchor line pulley 28 move back and forth relative to steering line 34 across the bottom of the body 3 of the rescue sled 1.

[0028] A set of soft (e.g., robber) grab handles 46 run along each side of the rescue sled 1 at the top of the body 3 to provide a continuous grip at which the sled can be carried to and from its transport vehicle to be deployed into and lifted out of the water. The grab handles 46 also provide the operator with support on which to hold while riding atop the sled 1. As is best shown in FIG. 6, a set of steering fins 48 are affixed to and extend downwardly from the bottom of the sled body 3 to help the sled operator maneuver the sled in the direction of the individual waiting to be rescued.

[0029] Referring concurrently to FIGs. 8-12 of the drawings, details are provided of a preferred method for using the rescue sled 1 of FIGs. 1-7 to rescue an individual being pulled through swift moving water. Prior to the rescue sled 1 being deployed in the water, the free end of the anchor line 5 that extends past the nose of the sled is tied to or looped around the anchor

50 that is implanted in the ground adjacent the water way (best shown in FIG. 8). The anchor 50 can be any one of a post, stake, tree or the like. In cases of emergency, the free end of the anchor line 5 can be held by another member of the rescue team who is not riding in the sled 1. [0030] FIGs. 9 and 10 show the individual to be rescued moving in the water at a rapid speed towards the rescue sled 1. As previously explained, the rescue team member who operates the rescue sled 1 can simply shift his body weight from side-to-side to approach the individual in need of being rescued. That is, the steering line pulley 30 rides along the stationary steering line

34 to one side of the sled or the other depending upon the direction in which the operator shifts his weight. By virtue of the steering line pulley 30 being coupled to the anchor line pulley 28 at the bottom of the sled 1 and at a location approximately midway along its length (best shown in

FIGs. 6 and 7), the water flows under the sled and not directiy against the nose. Thus, the operator is able to reliably steer and maneuver the sled towards the individual despite the power and speed of the water.

[0031] As an important step of the rescue process, prior to making the rescue, the speed of the rescue sled 1 is adjustably controlled to match the speed of the approaching individual.

Referring in this regard to FIGs. 11 and 12, the foregoing step is accomplished by operating the usual drag lever (designated 52 in FIG. 12) of the fishing reel 7 in order to dispense the rolled up anchor line 5. The anchor line 5 is controllably let out from the reel 7 until both the individual and the rescue sled 1 are floating side-by-side one another at the same speed.

[0032] Accordingly, the force and speed of the rapidly moving water are effectively neutralized. With the individual located alongside the rescue sled 1, the operator can grab hold of and pull the individual onboard the sled (best shown in FIG. 11). The rewind handle 9 of the fishing reel 7 can now be operated to retract the anchor line 5 and correspondingly pull the sled 1 towards the anchor 50 and the safety of the ground in which the anchor is implanted by which to conclude the rescue operation. It may be appreciated that the rescue is advantageously accomplished without requiring that the individual who may be injured or whose strength may be sapped, actively participate in the process by having to grab, hold onto or pull himself towards a rescue device as may otherwise be necessary in conventional rescue methods.
