DETAILED DESCRIPTION OF THE INVENTION

In order that the invention or inventions disclosed herein may be clearly understood and readily carried into effect, preferred embodiments of the invention(s) will now be described, by way of example only, with reference to the accompanying drawings.

Generally, the device of the present application is a permanently housed integrated hitch system that does not interfere with an interchangeable tool holder 16 or other part of a machine 12 thus increasing an off road machine's 12 productivity. The device can be positioned on the front or rear of a machine 12 in many various locations to haul trailers.

The off road machine may be a skid loader, excavator, small utility tractor loader or similar lifting type apparatus, but not limited to being actually attached to the lifting part of a machine.

Interchangeable tool holders 16 are a common component of many off road machines 12. The purpose of the interchangeable tool holder 16 is to make it more convenient for the operator to change tools such as forks, buckets and blades that interchangeably attach to tool holder 16. The integrated hitch system makes use of interchangeable tool holder 16 to create a positive and secure connection between a trailer and an off road machine 12.

The purpose of one embodiment of the invention is to utilize the visibility and versatility of a machine 12, like a skid loader and the available assortment of attachment tools 18 already on the market. One installs a tool 18 when needed and conveniently remove the tool 18 when not needed. Additionally, a multitude of currently available trailers or implements, of all sorts, can be moved by an off road machine 12 utilizing this integrated hitch system.

Referring to FIG. 1 the system according to at least one embodiment consists of a receiver hitch 14 attached directly and/or permanently by welding or other means onto an interchangeable tool holder 16 on the front 20 of the machine 12. A hitch attachment tool 18 slides into the receiver hitch 14 when needed and is removed when not needed.

Referring to FIG. 2 the system according to at least one embodiment consists of a receiver hitch 14 attached directly and/or permanently by welding or other means into an interchangeable tool holder 16 on the front 20 of the machine 22. A hitch attachment tool 18 slides into the receiver hitch 14 when needed and is removed when not needed. In this instance, the tool holder 16 is movable about a pivot point or points with a hydraulic ram power by the machine, as shown. The tool 18 may further include a pivoting member that pivots between an open position, e.g., allowing for a trailer to be attached to the trailer ball, and a closed position, e.g., securing the trailer to the trailer ball, as shown. The pivoting member may operate/be driven between the open and closed positions with a mechanical or hydraulic controller operated by a user of the machine 12.

Referring to FIG. 3 the system according to at least one embodiment consists of a receiver plate 24 attached directly and/or permanently by welding or other means on the rear 22 of the machine 12. A hitch attachment tool 18 bolts onto a receiver plate 24 when needed and is removed when not needed.

Referring to FIG. 4 the system according to at least one embodiment consists of a receiver plate 14 attached directly and/or permanently by welding or other means on the rear 22 of the machine 12. A hitch attachment tool 18 slides into the receiver plate 14 when needed and is removed when not needed.

Referring to FIG. 5 the system according to at least one embodiment consists of a receiver opening 28 permanently inserted into an interchangeable tool holder 16 on the front 20 of the machine 12. Interchangeable tool holder 16 is fitted with a spring loaded hitch pin 26 that interlocks with a corresponding hole or other engagement means in the hitch attachment tool 18. A hitch attachment tool 18 slides into the receiver opening 28 when needed and is removed when not needed.

Referring to FIG. 6 the system according to at least one embodiment consists of a non receiver style hitch 30 attached directly and/or permanently by welding or other means onto an interchangeable tool holder 16 on the front 20 of the machine 12.

Referring to FIG. 7, a top view of FIG. 6. A non receiver style hitch 30 is disclosed in the open position and shown in broken lines in the retracted position. In this instance, the receiver style hitch 30 pivots on the tool holder 16 between the open and retracted positions.

Referring to FIG. 8 the system according to at least one embodiment consists of a non receiver style hitch 32 attached directly and/or permanently by welding or other means onto an interchangeable tool holder 16 on the front 20 of the machine 12. The hitch 32 is disclosed in the retracted position.

Referring to FIG. 9 the system according to at least one embodiment consists of a non receiver style hitch 32 attached directly and/or permanently by welding or other means onto an interchangeable tool holder 16 on the front 20 of the machine 12. The hitch 32 is disclosed in the operating position.

Referring to FIG. 10 the system according to at least one embodiment consists of a receiver opening 28 permanently inserted into a push blade 32 on the front 20 of the machine 12. Push blade 32 is fitted with a keyed pushpin 34 or other means for removably attaching the tool 18 to the blade 32 or other hydraulically operated member of the machine 12. A hitch attachment tool 18 slides into the receiver opening 28 when needed and is removed when not needed. As can be appreciated, the operator of the machine 12 may hydraulically lower and raise the tool 18 into position from within the machine 12 using the existing hydraulic or other controls.

Referring to FIG. 11 this view discloses the angle of approach for the rear of a skid loader machine 12 where the obvious choice is to mount a hitch under the rear of the machine 12. The concept disclosed is that a hitch mounted under the rear of machine 12 would hinder machine 12 and would also cause extra drag or a point at which the machine 12 would get high centered. Thus an integrated hitch system for off road equipment of the above mentioned embodiments are of far superior design to the obvious choice of mounting a hitch under the rear of a on road or off road machine 12 to haul trailers.

There are many materials and configurations that can be used in constructing the devices disclosed herein by those skilled in the art including various materials, positions on the machine 12 and dimensions. In addition, it is clear that an almost infinite number of minor variations to the form and function of the disclosed invention could be made and also still be within the scope of the invention.

While the foregoing invention has been described in some detail for purposes of clarity and understanding, it will be appreciated by one skilled in the art, from a reading of the disclosure, that various changes in form and detail can be made without departing from the true scope of the invention.
