Universal quick detach multi-position accessory mount for vehicles or the like

Abstract

An accessory mounting system for vehicles or the like including one or more mounting rails, one or more mounting clamps, and one optional sliding rail per clamp. The mounting rail is trapezoidal in profile, and may include one or more pieces, and is permanently mounted to the vehicle frame, body, or other component and oriented with the wider of the two parallel faces facing outward from the vehicle. The mounting clamp assembly utilizes two opposed V-shaped jaws of an equal or slightly more acute angle than that represented by the angle between the wider of the two parallel faces of the mounting rail and one of its two adjoining non-parallel faces such that when the mounting clamp assembly is engaged on the mounting rail, the mounting rail nests between the two opposing jaws of the mounting clamp assembly, creating maximum surface area contact between the mounting clamp and the mounting rail in order to generate a very high coefficient of friction.

1 . An accessory mounting system for a vehicle comprising:
 at least one horizontally-oriented mounting rail attached to at least an end or a side of the vehicle, said mounting rail having a trapezoidal cross-sectional shape with the wider of two parallel faces facing outward from the vehicle;   at least one mounting clamp assembly detachably connected to said mounting rail for mounting an accessory to said vehicle; and   a mounting clamp assembly clamping and releasing means contained within said mounting clamp assembly for clamping and releasing said mounting clamp assembly from said mounting rail.   
   
   
       2 . The accessory mounting system as recited in  claim 1 , wherein said mounting clamp assembly comprises a pair of opposed V-shaped jaws each having an equal or slightly more acute angle than that represented by the angle between the wider of two parallel faces of the mounting rail and one of two adjoining non-parallel faces of the mounting rail such that when the mounting clamp assembly is engaged on the mounting rail, the mounting rail is arranged between said pair of opposing jaws of the mounting clamp assembly. 
   
   
       3 . The accessory mounting system as recited in  claim 2 , wherein said mounting clamp assembly clamping and releasing means causes said pair of V-shaped jaws to move toward or away from one another to provide a clamping and releasing action, respectively, upon said mounting rail. 
   
   
       4 . The accessory mounting system as recited in  claim 3 , wherein said mounting clamp assembly clamping and releasing means comprises a cam assembly for moving said pair of V-shaped jaws toward or away from one another. 
   
   
       5 . The accessory mounting system as recited in  claim 1 , wherein said mounting rail comprises:
 a mounting rail base plate permanently attached to a frame of said vehicle; and   a mounting rail cover slidably covering said mounting rail base plate.   
   
   
       6 . The accessory mounting system as recited in  claim 1 , further comprising at least one vertically-oriented rail, wherein said mounting clamp assembly further comprises at least one pair of gripping plates for gripping said slider rail. 
   
   
       7 . The accessory mounting system as recited in  claim 1 , further comprising a pair of said mounting clamp assemblies and a pair of corresponding horizontally-oriented support rails attached thereto. 
   
   
       8 . The accessory mounting system as recited in  claim 1 , wherein said mounting rail is a solid, single piece. 
   
   
       9 . The accessory mounting system as recited in  claim 1 , wherein said mounting rail is a solid, single stamped piece. 
   
   
       10 . The accessory mounting system as recited in  claim 9 , wherein said mounting rail is stamped to have a shape which permits nesting of a plurality of said mounting rails one within another. 
   
   
       11 . The accessory mounting system as recited in  claim 1 , wherein said mounting rail is a solid, single extruded piece having at least one horizontal groove arranged on a side facing said mounting clamp assembly. 
   
   
       12 . The accessory mounting system as recited in  claim 1 , wherein said mounting rail is a solid, single extruded piece having at least one horizontal groove arranged on a side facing said mounting clamp assembly, and further comprising:
 at least one large mounting clamp assembly and at least one small mounting clamp assembly,   wherein said large mounting clamp assembly comprises a pair of opposed V-shaped jaws each having an equal or slightly more acute angle than that represented by the angle between the wider of two parallel faces of the mounting rail and one of two adjoining non-parallel faces of the mounting rail such that when the large mounting clamp assembly is engaged on the mounting rail, the mounting rail is arranged between said pair of opposing jaws of the large mounting clamp assembly, and   wherein said small mounting clamp assembly comprises a pair of opposed V-shaped jaws each having the same angle as the pair of opposed jaws of the large mounting clamp assembly, one of the jaws of the small mounting clamp assembly adapted to be engaged on an edge of the mounting rail and the other one of the jaws of the small mounting clamp assembly adapted to be engaged on a lip of one of said horizontal grooves.   
   
   
       13 . An accessory mounting system comprising:
 at least one horizontally-oriented mounting rail attached to a larger structure, said mounting rail having a trapezoidal cross-sectional shape with the wider of two parallel faces facing outward from the structure;   at least one mounting clamp assembly detachably connected to said mounting rail for mounting an accessory to said structure; and   a mounting clamp assembly clamping and releasing means contained within said mounting clamp assembly for clamping and releasing said mounting clamp assembly from said mounting rail.
