Abstract
Abstract A lightweight, portable rescue sled for use on ice and in water for rescuing persons or animals who have fallen through the ice of a body of water such as a pond, river, or lake. The rescue sled includes a pair of lightweight spaced float members having a rescue stretcher supported therebetween for a major portion of the length of the float members, and a pair of hand rails attached to the float members and supported in an essentially upright position by a hand rail support assembly. In operation, the operator of the rescue sled positions himself in an opening defined at the rear of the rescue sled and applies pressure against the hand rails thereby causing the rescue sled to move rapidly across the ice toward a victim in the water. As the rescue sled is caused to move across the ice, the weight of the rescue sled and its operator are spread over a large area of the ice thereby minimizing the danger of breaking through the ice before reaching the victim.

Claim 1
Independent Claim
284 words
A rescue sled for use by an operator on an ice surface and in water during rescue operations, comprising: a pair of elongated, spaced float members, each having a glide surface; body-receiving means disposed between the pair of float members for receiving and supporting the body of a victim thereon, said body-receiving means being disposed along the pair of float members for a distance less than thE total length of the float members, said body-receiving means and float members defining an an opening at one end of the rescue sled for an operator to position himself within while operating the rescue sled on an ice surface; a pair of movable hand-grasping members, one attached to each of the float members, each of the hand-grasping members being capable of movement between a first position inboard of the rescue sled and a second position outboard of the rescue sled; and support means for supporting each of the hand-grasping members in a position intermediate the associated first and second positions and inboard of the rescue sled, said hand-grasping members including respective hand-receiving portions proximate to the opening defined at said one end of the rescue sled when the hand-grasping members are in the intermediate positions, said hand-receiving portions being adapted to receive the hands of an operator while the operator is positioned within said opening and enabling the operator to impart motion to the rescue sled to cause the rescue sled to glide along an ice surface when force is applied by the operator against the handreceiving portions of the hand-grasping members, a significant portion of the weight of the operator being distributed over the area of the rescue sled when the rescue sled is in motion.
Claim 2
Dependent Claim
284 words
A rescue sled for use by an operator on an ice surface and in water during rescue operations, comprising: a pair of elongated, spaced float members, each having a glide surface; body-receiving means disposed between the pair of float members for receiving and supporting the body of a victim thereon, said body-receiving means being disposed along the pair of float members for a distance less than thE total length of the float members, said body-receiving means and float members defining an an opening at one end of the rescue sled for an operator to position himself within while operating the rescue sled on an ice surface; a pair of movable hand-grasping members, one attached to each of the float members, each of the hand-grasping members being capable of movement between a first position inboard of the rescue sled and a second position outboard of the rescue sled; and support means for supporting each of the hand-grasping members in a position intermediate the associated first and second positions and inboard of the rescue sled, said hand-grasping members including respective hand-receiving portions proximate to the opening defined at said one end of the rescue sled when the hand-grasping members are in the intermediate positions, said hand-receiving portions being adapted to receive the hands of an operator while the operator is positioned within said opening and enabling the operator to impart motion to the rescue sled to cause the rescue sled to glide along an ice surface when force is applied by the operator against the handreceiving portions of the hand-grasping members, a significant portion of the weight of the operator being distributed over the area of the rescue sled when the rescue sled is in motion.
Claim 3
Dependent Claim
74 words
A rescue sled in accordance with claim 1 wherein the support means includes: a support structure between the pair of float members; a pair of elongated rod members, one associated with each of the hand-grasping members, each of the rod members being attached at one end to the support structure; and a pair of locking mechanisms, one attached to the opposite end of each of the rod members and engaging the associated hand-grasping member.
Claim 4
Dependent Claim
22 words
A rescue sled in accordance with claim 2 wherein each of the locking mechanisms includes means for disengaging the associated hand-grasping member.
Claim 5
Dependent Claim
54 words
A rescue sled in accordance with claim 1 wherein: each of the movable hand-grasping members is capable of movement through an angle of approximately 180*, each of the hand-grasping members being capable, when in the second position, and when the rescue sled is in water, of being grasped by a victim in the water.
Claim 6
Dependent Claim
45 words
A rescue sled in accordance with claim 1 wherein the support means includes means for enabling an operator to brace himself and maintain his position on the rescue sled when the operator is in a prone position on the rescue sled during a rescue operation.
Claim 7
Dependent Claim
78 words
A rescue sled in accordance with claim 1 wherein: each of the pair of float members has a generally rectangular cross-section and includes a core of an expanded polystyrene material; the body-receiving means includes a stretcher; and the hand-grasping members are cylindrical hand rails, each of the cylindrical hand rails including first and second end portions attached to the opposed end regions of the associated float member and a longitudinal portion between the first and second end portions.
Claim 8
Dependent Claim
32 words
A rescue sled in accordance with claim 6 further comprising: means attached to each of the float members at the said one end of the rescue sled for receiving a reel line.
