The following includes information that may be useful in understanding the present invention(s). It is not an admission that any of the information provided herein is prior art, or material, to the presently described or claimed inventions, or that any publication or document that is specifically or implicitly referenced is prior art.
The present invention relates generally to the field of recreational vehicles and more specifically relates to a boat and boat trailer loading system.
Boats have been used in the fishing industry and for transportation of people for many years. While boating was predominately a means of gathering food for subsistence since early history, boating for recreation has increased exponentially in the last century. The watercraft industry has reported sales in excess of 17 billion annually and the U.S. Coast Guard reports that there are approximately 16.7 million owners of boats that are less than 25 feet in length in the U.S. About half of these owners also have a trailer for towing their boat to a location where the boat can be launched and used. These trailers may be dangerous to pull, and may prevent owners from pulling other recreational vehicles.
As an alternative boat owners often purchase small boats such that they may be transported on the top of a vehicle, placed there by manual means. This may prove dangerous if the boat is not secured in place using suitable fastening means, as the boat may come loose and fall of into traffic. A boat falling off into traffic may endanger other motorists and often destroys the boat. Additionally, lifting a boat into place may cause an individual to undergo strain from lifting, potentially causing back problems. Using this method, once the owner has arrived at the body of water he/she is left with no trailer by which to move the boat. It is desired that the boat and trailer be available at the final destination.
Various attempts have been made to solve the above-mentioned problems such as those found in Pub. No. 2004/0161322; U.S. Pat. Nos. 3,411,644; 5,741,110; 3,734,321; 5,511,928; and 5,586,856. This prior art is representative of boat hauling means. None of the above inventions and patents, taken either singly or in combination, is seen to describe the invention as claimed.
Ideally, a boat and boat trailer loading system should be user-friendly and safe, yet would operate reliably and be manufactured at a modest expense. Thus, a need exists for a reliable boat and boat trailer loading system to quickly load a boat trailer with a mounted boat, and to avoid the above-mentioned problems.
In view of the foregoing disadvantages inherent in the known boat loading system art, the present invention provides a novel boat and boat trailer loading system. The general purpose of the present invention, which will be described subsequently in greater detail, is to provide boat loading and transporting means leaving an unobstructed trailer hitch for hauling a second recreational item such as a camping trailer.
A boat and boat trailer loading system as disclosed herein preferably comprises a head frame assembly having a winch with a cable, and a tail frame assembly comprising an upper ramp system including an upper left ramp and an upper right ramp. The upper ramp system has a distal end and a proximate end. The boat and boat trailer loading system further comprises a lower ramp system including a lower left ramp and a lower right ramp, the lower ramp system having a first end and a second end. Additionally, a cradle frame member is included in preferred embodiments. The head frame assembly and the tail frame assembly are mountable to a vehicle frame, preferably to the top surface of a pickup cargo box. The head frame assembly comprises a left side and a right side preferably non-removably joined by a head-cross-member. The left side and the right side of the head frame assembly each have two upright support-columns.
The winch may be removably fastened to the vehicle frame or, in some embodiments, to the front wall of the pickup cargo box (or in other embodiments to the head frame assembly) and preferably has an electric motor, a hook on the cable, and a remote controller. In embodiments where the winch is removably fastened to the head frame assembly these versions may have a roller assembly having four rollers including a first roller affixed to a top side, a second roller to a bottom side, a third roller to a left side, and fourth roller to a right side of an opening such that the winch cable is able to roller-pass therethrough to attach to the boat trailer frame. The head frame assembly may comprise at least one pulley in an embodiment wherein the winch is mounted to the front wall of a pickup cargo box. The cradle frame member is preferably non-removably connected to the tail frame assembly. The tail frame assembly has a left side and a right side upright member joined by at least one cross-member. The left side and right side upright members of the tail frame assembly comprise two tubular columns each which may be square tubing, but also may be round tubing in other embodiments.
The tail frame in preferred embodiments comprises a left wheel cradle and a right wheel cradle, each one having a locking pin (or other retaining means) such that the tires of the boat trailer are able to be independently locked into the wheel cradles during transport. The left wheel cradle and the right wheel cradle are able to nestibly support the wheels of the boat trailer when the boat trailer with the boat mounted thereon are mounted onto the head frame assembly and the tail frame assembly (keeping it in place.) When the boat is mounted onto the boat trailer and loaded for transport on the boat trailer loading system, the boat and boat trailer are mount-situated above and (substantially) parallel to the vehicle frame. The cradle frame member comprises a center roller wherein the tongue of the boat trailer is able to be roller-guided forwardly and rearwardly by the cable of the winch when being loaded and unloaded. The center roller is horizontally fastened to the top surface of the cross member at a lower height than the surface-plane of the left side and the right side of the tail frame such that the cable, the boat, and the boat trailer frame do not contact the tail frame during at least one boat-trailer-loading-procedure. In this embodiment the center roller is orientated perpendicular to the frame.
The distal end of the upper ramp system is removably connectable to the cradle frame member and the proximate end of the upper ramp system is removably attached to the second end of the lower ramp system for loading and unloading (is stored during transport.) When loading for example the first end of the lower ramp system is in contact with the ground surface such that the wheels of the boat trailer are able to traverse an incline created by the lower ramp system and the upper ramp system. The cable of the winch is removably coupleable to the boat trailer and (the boat trailer having a boat located thereon) are able to be winch-manipulated onto the head frame and tail frame assemblies of the present invention. Forward traverse of the boat trailer is accomplished when the boat trailer is pulled via the winch and first contacts and rides upon the lower left ramp and the lower right ramp, then next sequentially the boat trailer moves to the upper left ramp and the upper right ramp, then the wheels of the boat trailer set into the cradle frame member. In this sequence the boat trailer is able to be moved on its wheels into a loaded position (and reversed to perform an unload.)
The upper ramp system and the lower ramp system preferably comprise couplers such that the upper ramp system and the lower ramp system remain connected and supported while in use, and are able to be separated from each other for transport. The boat trailer is able to be cable-pulled up the lower ramp system onto the upper ramp system then onto the cradle frame member for transport-attachment above the plane of the vehicle frame. When the boat trailer with the boat thereon is mounted onto the head frame and the tail frame, a trailer hitch located at the rear of the vehicle is able to remain unobstructed allowing the vehicle to tow a second trailer. The truck is then free to pull other recreational devices such as camping trailers or the like.
A method of use for a boat and boat trailer loader system as disclosed herein may comprise the steps of: attaching a lower ramp system and an upper ramp system to a tail frame assembly; extending a cable through a roller assembly located on a head frame assembly; attaching the cable to a trailer frame with a boat mounted thereon; pulling the trailer with the boat up an inclined plane formed by the lower ramp system and the upper ramp system (attached to each other); positioning the wheels of the trailer into a left wheel cradle and a right wheel cradle (simultaneously); locking the wheels of the trailer with the boat mounted thereon to a cradle frame member; hauling the trailer with the boat to a water recreation area; unlocking the wheels of the trailer with the boat; and extending the cable using the winch to lower the trailer with the boat to a ground surface such that the boat and trailer may be used.
