A collapsible sled for transporting articles comprising a pair of box-like sections within each of which there is pivotably mounted a pair of runners. The runners can be pivoted so as to be completely received within the box-like sections for transport, and the box-like sections can be closed upon each other to form a complete box with the runners disposed therein. Fasteners including a plurality of keepers for slidably receiving a plurality of locking members, respectively, are provided for securing the runners and the box-like sections in their operable positions. The fasteners eliminate any need for conventional threaded fasteners, are very convenient to use, and provide a strong and effective fastening arrangement.

A collapsible sled according to claim 2, wherein: each said keeper member comprises a pair of oppositely arranged flanges having substantially L-shaped cross sections; and said flanges are provided on opposite respective sides of said aperture in said side wall. 4. A collapsible sled according to claim 3, wherein: each said locking member comprises a pair of prongs; each said projection of said runner is provided with a pair of oppositely arranged grooves; and said prongs of said locking member are adapted to be slidably received within said L-shaped flanges of said keeper member and said grooves of said projection. 5. A collapsible sled according to claim 4, wherein: said flanges of said keeper member and said grooves of said projection are each arranged such that a length dimension thereof extends substantially in the longitudinal direction of said sled. 6. A collapsible sled according to claim 4, wherein: said prongs of said locking member and said flanges of said keeper member are each tapered. 7. A collapsible sled according to claim 1, wherein: said second means and said third means are fabricated entirely of a polyethylene plastic material. 8. A collapsible sled for transporting articles, comprising: a front section and a rear section, said sections being pivotably interconnected; one of said sections being pivotable with respect to the other through an arc of approximately 180°; each said section comprising a box-like member which includes a support platform, front and rear depending walls, and opposite side walls; each said section having a pair of runners pivotally connected thereto by hinge means; each said runner being pivotal from a position in which it is entirely received within said box-like member to an operable position in which said runner extends downwardly from and substantially perpendicularly to said platform; first means for locking said front and rear sections together in a collapsed condition with said runners disposed therein; second means for locking said runners in said operable position; third means for locking said front and rear sections in an open operable position; each said second and third means comprising a locking member which is slidably received in a keeper member; said third means comprising: a plurality of said keeper members, said keeper members being arranged in spaced positions on inside surfaces of said front wall of said rear section; said front wall being provided with an aperture adjacent each said keeper member; said rear wall of said front section being provided with projections arranged in corresponding relation to said apertures such that said projections project through said apertures when said front and rear sections are in said open operable position thereof; a plurality of locking members, corresponding in number to said keeper members; and each said locking member being slidably receivable in one of said keeper members so as to operatively cooperate with said member and a corresponding one of said projections so as to lock said front and rear sections in said open operable position. 9. A collapsible sled according to claim 8, wherein: each said keeper member comprises a pair of oppositely arranged flanges having substantially L-shaped cross sections; and said flanges are provided on opposite respective sides of said aperture in said front wall. 10. A collapsible sled according to claim 9, wherein: each said locking member comprises a pair of prongs; each said projection of said runner is provided with a pair of oppositely arranged grooves; and said prongs of said locking member are adapted to be slidably received within said L-shaped flanges of said keeper member and said grooves of said projection. 11. A collapsible sled according to claim 10, wherein: said flanges of said keeper member and said grooves of said projection are each arranged such that a length dimension thereof extends substantially in the lateral direction of said sled. 12. A collapsible sled according to claim 10, wherein: said prongs of said locking member and said flanges of said keeper member are each tapered. 13. A collapsible sled according to claim 11, wherein: a further one of said plurality of said keeper members and the grooves of one of said projections corresponding thereto are arranged such that a length dimension thereof extends substantially at right angles to the longitudinal and lateral directions of said sled; and said further one of said keeper members and said projection corresponding thereto are arranged at substantially a central portion of said sled. 14. A collapsible sled according to claim 1, wherein: said snow blade runners are pivotably directly connected to said box-like members about a pivot axis extending within said box-like members. 15. A collapsible sled according to claim 1, wherein: said snow blade runners have a pivot axis which is disposed within said box-like member and upwardly of the lower edges thereof; and said snow blade runners are concealed within said box-like members when said snow blade runners are in an inoperable position for transport of said sled. 16. A collapsible sled according to claim 15, wherein: said box-like members are pivotably connected at adjacent lower edges thereof; said box-like members are rotatable with respect to each other when said snow blade runners are received therein, into facing contact with each other along their lowermost edges to form a closed box-like configuration with said snow blade runners confined therein; and said box-like members are provided with means for securing said box-like members in said closed position. 17. A collapsible sled for transporting articles, comprising: a front section and a rear section, said sections being pivotably interconnected; one of said sections being pivotable with respect to the other through an arc of approximately 180°; each said section comprising a box-like member which includes a support platform, front and rear depending walls, and opposite side walls; each said section having a pair of runners pivotally connected thereto by hinge means; each said runner being pivotal from a position in which it is entirely received within said box-like member to an operable position in which said runner extends downwardly from and substantially perpendicularly to said platform; first means for locking said front and rear sections together in a collapsed condition with said runners disposed therein; second means for locking said runners in said operable position; third means for locking said front and rear sections in an open operable position; each said second and third means comprising a locking member which is slidably received in a keeper member; said second means and said third means each comprising a plurality of said locking members and a plurality of said keeper members arranged in spaced apart relation; and said locking members being interchangeable such that each said locking member may be slidably inserted in any one of said keeper members. 18.
