DETAILED DESCRIPTION OF THE INVENTION

(9) Referring to FIG. 1, the tow-bar mounting system 10 provides for the removable and adjustable attaching of a variety of accessories to a vehicle's tow-bar structure such as a bumper or trailer hitch, as shown. The tow-bar mounting system 10 provides clamping mount units 20 and inserting mount units 30 for attaching accessories, such as the lights, reflector, electrical socket, camera, and sensor shown.

(10) The clamping mount units 20 and the inserting mount units 30 are made of material suitable to the purpose and to the vehicle-bumper environment and conditions. A metal such as steel is appropriate if it is inherently rust-proof or is coated with a paint, epoxy, bonded powder coating, or rubberized coating, or is otherwise treated to resist rust.

(11) Referring to FIG. 2, each clamping mount unit 20 is in the form of a two-part hinged clamp. Each clamping mount unit 20 provides a plain angled subunit 21 and a mounting angled subunit 24 which can be fit together to surround the tow-bar structure, and can be fastened around the tow-bar structure. The plain angled subunit 21 has at one end a hinging tab 22 and near the other end a fastening hole 23. The mounting angled subunit 24 has at one end a hinging slot 25 and at the other end a fastening tab 26 and dual extended mounting arms 27 having corresponding dual accessory mounting holes 28. The hinging tab 22 and the corresponding hinging slot 25 can be fit together to provide a hinge, as shown.

(12) Referring additionally to FIG. 3 and FIG. 4, in use, a clamping mount unit 20 is fastened to the tow-bar structure by placing the separate plain angled subunit 21 and mounting angled subunit 24 around the tow-bar, placing the hinging tab 22 into the hinging slot 25, thereby joining the subunits in a hinged joint, bringing the free end of the plain angled subunit 21 close to the fastening tab 26 of the mounting angled subunit 24, and fastening the free end of the plain angled subunit 21 and the fastening tab 26 together, thereby clamping upon the tow-bar structure. The fastening tab 26 is provided with a hole corresponding to the fastening hole 23 of the free end of the plain angled subunit 21, and the fastening can be accomplished using a bolt and nut, as shown, or another fastener, including a locking fastener or a one-way screw.

(13) Referring to FIG. 5, in use, an accessory, such as the light shown, is mounted to the mounting angled subunit 24 through one or both of the dual accessory mounting holes 28. The use of both of the dual accessory mounting holes 28 for one accessory is appropriate for achieving a mounting which will not rotate or slip in use. Two accessories of the appropriate size and shape can be mounted to one mounting angled subunit 24, each using one of the dual accessory mounting holes 28.

(14) Referring to FIG. 6, each inserting mount unit 30 is of a form which can be partially inserted into the tow-bar structure to provide an additional mounting point for accessories. The inserting mount unit 30 provides an inserting body 31 and a single extended mounting arm 32 having one or more accessory mounting holes 33. When two accessory mounting holes 33 are provided, a non-rotating or non-slipping attachment can be made, as above.

(15) Referring to FIG. 7, in use on a tow-bar structure such as the vehicle trailer hitch shown, the clamping mount units 20 and inserting mount units 30 of the tow-bar mounting system 10 provide for the removable and adjustable attaching of a variety of accessories to the vehicle's tow-bar structure.

(16) Many other changes and modifications can be made in the system and method of the present invention without departing from the spirit thereof. I therefore pray that my rights to the present invention be limited only by the scope of the appended claims.
