The present invention relates to vehicle accessory field. More specifically, it relates to a winch tray mounting system for vehicles.
A winch is a popular accessory for vehicles intended for off-road use. A winch is generally mounted onto a vehicle by attaching itself to a winch tray. When the winch is located “outside of the vehicle” (defined hereinafter as being located either in front of the vehicle's front bumper or behind the vehicle's rear bumper), the winch tray is usually attached to an intermediary apparatus that is then attached to the vehicle. Examples of such intermediary apparatus are front grill guard, front bumper, rear bumper, a hitch receiver, etc. The intermediary apparatus may or may not be attached to the structural frame of the vehicle. The winch tray itself is not attached to the vehicle's structural frame. Accordingly, the mechanical loads applied by operation of a winch attached to the winch tray (hereinafter referred to as “applied mechanical loads”) are generally not translated to the vehicle's structural frame. Without the ability to transfer the applied mechanical loads to the vehicle's structural frame, the conventional winch mounting system is limited in its strength and load capacity.
The present invention addresses the above-discussed limitations by providing a winch tray mounting system with robust strength and load capacity. The winch tray mounting system of the present invention includes a winch tray and a mounting assembly comprising at least two mounting brackets for attaching the winch tray to frame rails of a vehicle wherein when the winch tray mounting system is attached to the vehicle: (i) each of the at least two mounting brackets is directly attached to both the winch tray and one of the frame rails; (ii) the winch tray is located outside of the vehicle; (iii) the winch tray mounting system and the frame rails form a rigid structural body frame; and (iv) the winch tray mounting system (e.g., directly) translates applied mechanical loads to the frame rails.
The present invention also provides a method for attaching a winch tray to a vehicle comprising: providing a winch tray mounting system comprising a winch tray and a mounting assembly comprising a first mounting bracket and a second mounting bracket; attaching the first mounting bracket and the second mounting bracket both directly to the winch tray; attaching the first mounting bracket directly to a first frame rail of a vehicle at a first location that allows the winch tray to be located outside of the vehicle; attaching the second mounting bracket directly to a second frame rail of the vehicle at a second location that allows the winch tray to be located outside of the vehicle; wherein (i) the winch tray mounting system, the first frame rail and the second frame rail form a rigid structural body frame; and (ii) the winch tray mounting system (e.g., directly) translates applied mechanical loads to the first frame rail and the second frame rail.
The present invention will be more clearly understood when considering the accompanying drawing of which:
I. Definitions
The following terms are intended to have the following general meanings as they are used herein.
1. Applied mechanical loads: the mechanical loads applied by operation of a winch attached to the winch tray
2. Directly attached or attaching directly: a direct attachment or connection; the attached components are either (i) in direct communication or physical contact with each other; or (ii) the attached components are in communication or contact with each other through one or more connecting materials that still allow the winch tray mounting system and the frame rails to form a rigid structural body frame wherein the winch tray mounting system can still translates applied mechanical loads to the frame rails. For example, two components are considered directly attached even if lock washers and/or other similar material separates the two components resulting in no direct physical contact between the two components.
3. Frame rail(s): the structural frame rail(s) of a vehicle.
4. Outside of the vehicle: located either in front of the vehicle's front bumper or behind the vehicle's rear bumper.

When the winch tray mounting system (100 or 200) is attached to the frame rails (146, 149), the winch tray (102 or 202) is located, outside of the vehicle and the winch tray mounting system (100 or 200) and the frame rails (146, 149) form a rigid structural body frame. This rigid structural body frame allows the winch tray mounting system (100 or 200) to directly translate the applied mechanical loads to the frame rails (146, 149) providing robust strength and load capacity, and additional safety.
