Modular fish scale sled
A portable sled for transporting cargo in outdoor environments comprises overlapping High-Density Polyethylene (HDPE) sheets arranged in a fish-scale configuration. The design features a structural aluminum body with eye bolts at the front and nylon straps for securing cargo. The sled's fish-scale assembly reduces drag, optimizes weight distribution, and minimizes snagging. Heat-treated HDPE sheets 101 maintain a curved shape when assembled but flatten for storage. The sled incorporates high-visibility colors for safety and is buoyant for water-based operations. Its modular design allows for easy assembly and disassembly in the field, making it highly portable and versatile for various outdoor scenarios.
1. A portable sled for transporting cargo in outdoor environments, comprising: a plurality of High-Density Polyethylene (HDPE) panels arranged in an overlapping fish-scale configuration; one or more protective bodies consisting of aluminum locking plates positioned near the front of the sled to reinforce a leading edge; a plurality of eye bolts attached to the one or more protective bodies at the front portion of the sled; a plurality of straps extending through dedicated slots in the plurality of HDPE panels for securing cargo; and wherein the sled is disassemblable for compact storage and transportation.
2. The portable sled of claim 1 , wherein the fish-scale configuration of the HDPE panels reduces drag, optimizes weight distribution, and minimizes snagging on obstacles.
3. The portable sled of claim 1 , wherein the HDPE panels are between 1-10 millimeters thick.
4. The portable sled of claim 3 , wherein the HDPE panels are approximately 3 millimeters thick.
5. The portable sled of claim 1 , wherein the sled incorporates high-visibility colors for safety and visibility in outdoor environments.
6. The portable sled of claim 1 , wherein the sled is buoyant and suitable for use in water-based operations.
7. A method of assembling a portable sled for transporting cargo in outdoor environments, comprising:
laying out a plurality of High-Density Polyethylene (HDPE) sheets;
arranging the HDPE panels in a predetermined sequence;
interlocking the HDPE panels to form an overlapping fish-scale configuration;
attaching a structural body to a front portion of the interlocked HDPE panels, wherein the structural body comprises aluminum locking plates being positioned near the front of the sled;
connecting eye bolts through pre-drilled holes in the aluminum locking plates of the structural body;
threading nylon straps through dedicated slots in the HDPE panels; and
verifying the integrity of the fish-scale assembly.
8. The method of claim 7 , further comprising heat-treating the HDPE panels to maintain a curved shape when assembled and flatten for storage.
9. The method of claim 7 , wherein the fish-scale configuration of the HDPE panels reduces drag, optimizes weight distribution, and minimizes snagging on obstacles.
10. A system for transporting cargo in outdoor environments, comprising: a portable sled with a plurality of High-Density Polyethylene (HDPE) sheets arranged in an overlapping fish-scale configuration; one or more structural bodies comprising aluminum locking plates positioned near a front of the sled to reinforce a leading edge; a plurality of eye bolts installed through pre-drilled holes in the one or more structural bodies at the front portion of the sled; a plurality of nylon straps for securing cargo; a towing mechanism selected from the group consisting of a harness for human-powered towing and a towing rope for motorized vehicle towing; and wherein the sled is disassemblable for compact storage and transportation.
11. The system of claim 10 , wherein the sled incorporates high-visibility colors for safety and visibility in outdoor environments.
