Abstract
A car haul trailer for transporting vehicles which includes a trailer frame with a base frame and a pair of spaced apart upstanding side frames between which are mounted a plurality of fixed and movable track assemblies so that the track assemblies can be positioned in a plurality of positions to accommodate different loads of vehicles to be transported.
Claims12
A car haul trailer for transporting vehicles comprising:
- a base frame having a front end and a rear end;
- a pair of spaced apart side frames assemblies mounted on said base frame along opposite sides thereof;
- each of said frame assemblies including an upstanding, arched primary side rail having opposite ends and a first prescribed radius of curvature, one end of said primary side rail connected to said base frame adjacent the rear end thereof and the other end of said primary side rail connected to said base frame intermediately of the rear and front ends thereof so that said primary side rail projects above said base frame and lies in a generally vertical plane;
- an upstanding arched secondary side rail having opposite ends and a second prescribed radius of curvature, one end of said secondary side rail connected to said base frame adjacent the front end thereof;
- and a gusset assembly connecting the other end of said secondary side rail to said primary side rail intermediate its ends;
- and
- a plurality of vehicle supporting track assemblies positioned between and mounted on said side frames to support the vehicles to be transported, said gusset assemblies connecting said secondary side rails to said primary side rails so that forces exerted on said secondary side rails by said track assemblies and directed along said secondary side rails generally toward the rear end of said base frame will be transferred through said gusset assemblies to said primary side rails and along said primary side rails to said base frame adjacent the rear end thereof and so that forces exerted on said primary side rails by said track assemblies rearwardly of said secondary side rails directed along said primary side rails generally toward the front end of said base frame will be directed to said base frame partly through said gusset assemblies and said secondary side rails to said base frame adjacent the front end thereof and partly through said primary side rails to said base frame intermediate the ends thereof.

A track assembly for use on a car haul trailer to support vehicles for transport on the car haul trailer including:
- a primary subassembly adapted for pivotal movement about a primary pivot axis, said primary subassembly including a U-shaped frame comprising a central section and a pair of spaced apart side sections at opposite ends of said central section, said side sections pivoted about said primary pivot axis at their ends opposite said central section and said frame defining an open space therein between the primary pivot axis and the central section thereof;
- a secondary subassembly pivotally mounted in the open space in said primary subassembly for pivotal movement about said primary pivot axis so that said secondary subassembly is pivotal with respect to said primary subassembly;
- and
- interconnect means connecting said secondary subassembly with said primary subassembly so that said secondary subassembly is pivoted with said primary subassembly as said primary subassembly is pivoted about said primary pivot axis, said interconnect means further selectively pivoting said secondary subassembly about said primary pivot axis with respect to said primary subassembly.

A mechanism for selectively securing a wheeled vehicle through attachment points on a vehicle to a hauling trailer for transportation thereon including
- a pair of spaced apart track sections for supporting at least one pair of wheels on opposite sides of the vehicle;
- a tie down assembly operatively associated with said track sections, said tie down assembly comprising:
- at least one frame member defining an open space along the length thereof,
- a plurality of guide members mounted on said frame member and extending across said open space at spaced apart intervals to divide said open space into a plurality of subspaces,
- at least one flexible member adapted to be attached at one of its ends to one of the attachment points on the vehicle;
- at least one tensioning mechanism connected to the opposite end of said flexible member to selectively take up said flexible member
- so that that end of said flexible member to be attached to the vehicle can be passed around a selected one of said guide members through the subspace associated therewith, then attached to the attachment point on the vehicle, and said tensioning mechanism used to tighten said flexible member to apply a force to the vehicle directed toward said track section whose angle is determined by said guide member selected around which said flexible member extends.

A car haul trailer for transporting vehicles comprising:
- a trailer frame including upright support posts therein;
- a top rail connected to the top of said support post, and having a section thereof omitted adjacent said support post;
- and a gusset assembly connecting those ends of said side rail across the omitted section to define a vertically extending opening therethrough adjacent said support post;
- at least one track assembly;
- and
- a positioning mechanism connecting said track assembly to said support post for movement therealong to position said track assembly, said positioning mechanism including a slide tube slidably mounted on said support post and connected to said track assembly, a positioning cylinder having an extendable piston rod positioned adjacent said support post, and an extension member connecting said piston rod to said slide tube, said extension member extending above said slide tube, and said extension member and said piston rod in vertical registration with said opening through said gusset assembly so that said piston rod and said extension can extend through said vertically extending opening through said gusset assembly above said trailer frame as said slide tube approaches the upper limit of its travel along said support post to increase the effective range of movement of said slide tube along said support post by said positioning cylinder.

A car haul trailer for transporting vehicles comprising:
- a trailer frame assembly having a longitudinal axis;
- a plurality of vehicle supporting track assemblies mounted in said trailer frame assembly to support vehicles to be transported, at least one of said vehicle supporting track assemblies including a primary subassembly pivotally mounted on said trailer frame about a primary pivot axis oriented generally normal to the longitudinal axis, said primary subassembly comprising a U-shaped frame including a central section and a pair of spaced apart side sections at opposite ends of said central section, said side sections pivoted about said primary pivot axis at their ends opposite said central section and said U-shaped frame defining an open space between said central section and said primary pivot axis;
- a secondary subassembly pivotally mounted in the open space in said primary subassembly for pivotal movement about said primary pivot axis so that said secondary subassembly is pivotal with respect to said primary subassembly;
- and
- interconnect means connecting said secondary subassembly with said primary subassembly so that said secondary subassembly is pivoted with said primary subassembly as said primary subassembly is pivoted about said primary pivot axis, said interconnect means further selectively pivoting said secondary subassembly about said primary pivot axis with respect to said primary subassembly.
