## Background
BACKGROUND OF THE INVENTION
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.
1. Field of the Invention
The present invention relates generally to the field of personal watercraft docking systems and more specifically relates to blu water lift systems.
2. Description of Related Art
Using a personal watercraft is a favorite past time for many people. Personal watercraft can frequently be seen while being used in the ocean or on lakes. A personal watercraft may be defined as a water-use vehicle that a rider sits or stands on (rather than inside of, as in a boat) and is typically less than 13 feet in length. Typically, personal watercraft have an inboard engine that drives a pump jet with a screw-shaped impeller to create thrust for both propulsion and steering. Due to the speed and maneuverability characteristics that personal watercraft possess, the military and some police departments use personal watercraft for patrol and enforcement activities.
Generally, personal watercraft are used in relatively small geographic areas or bodies of water and need a transport method to allow them to be moved to different locations. Over land, a small, wheeled trailer may be attached to a land vehicle, and the personal watercraft may be placed on the trailer and towed behind the land vehicle. If the user is also transporting a small boat to the location, then a second vehicle and an additional boat trailer may be needed, as well. Often, a pleasure boat may be used to transport the personal watercraft. In this case, a device is required to store and transport the personal watercraft, as well as provide a means to launch and retrieve the personal watercraft to and from the water. Launching systems, which may include hydraulic lifting mechanisms, can be complex and subject to reliability issues that relate to the operation of complex machines. A suitable solution is desired.
Several attempts have been made to solve the above-mentioned problems such as those found in U.S. Pat. No. 6,003,463 to Giesler, U.S. Pat. No. 4,878,450 to Schmidt, U.S. Pat. No. 6,327,992 to Martin, U.S. Pat. No. 6,786,170 to Trowbridge, and U.S. Pat. No. 5,090,841 to Penick, et. al. This art is representative of personal watercraft docking systems. However, none of the above inventions and patents, taken either singly or in combination, is seen to describe the invention as claimed.
Preferably, a personal watercraft docking system should provide a device to raise and lower a personal watercraft into water and to hold the personal watercraft for transport and, yet would operate reliably and be manufactured at a modest expense. Thus, a need exists for a reliable blu water lift system to avoid the above-mentioned problems.
BRIEF SUMMARY OF THE INVENTION
In view of the foregoing disadvantages inherent in the known personal watercraft docking system art, the present invention provides a novel blu water lift system. The general purpose of the present invention, which will be described subsequently in greater detail is to provide a device to raise and lower a personal watercraft into water and to hold the personal watercraft for transport.
Generally speaking, blu water lift system is designed to lift a personal watercraft or a tender (up to 1500 lbs and up to 12.5 feet in length) out of the water for transport on the back of a boat for easy transport and easy storage. The blu water lift system is easy to operate. First, attach the winch hook from the blu water lift system to the watercraft. Second, use the remote activator to raise the personal watercraft to the fold down loading ramp and the winch will pull the watercraft toward the nose tower until the hull is adjacent to the nose cradle. The remote activator may further be used to elevate the blu water lift system adjacent to the swim platform of a boat. The supports and struts are adjustable to fit most styles of boat swim platforms. Hardware and supports are made out of stainless steel and the rack system and adjustable underwater struts are made out of aluminum or double walled aluminum, as per design.
The blu water lift assembly may be useful for removably attaching the frame and the carriage structure to the watercraft, operating the at least one pivot mounting arm via the electrically-operated actuator and the remote activator, and operating the loading ramp for manipulating the watercraft between the in-transport condition and a non-transport condition.
A blu water lift system comprises a blu water lift assembly, which may comprise a frame, a carriage structure, at least one pivot mounting arm, an electrically-operated actuator, a loading ramp, and a remote activator. The frame may comprise a square-beam, which may further comprise a first-end and a second-end, useful for providing structure to attach the nose tower and the carriage structure. The second-end may comprise a nose tower, which may further comprise a winch receiver, a hook receiver, and a nose cradle. The nose cradle may comprise at least one cushioned bumper. The nose tower may comprise at least one horizontal position useful for accommodating varying lengths of at least one watercraft. The blu water lift assembly may further comprise corrosion-resistant materials to promote longevity in water-environments.
The carriage structure may comprise a hull-resting plate and at least one carriage rail, which may further comprise a spar in preferred embodiments. The at least one carriage rail may be useful for retaining a hull of a watercraft during an in-transport condition. The carriage structure may comprise a left carriage rail and a right carriage rail, The left carriage rail may comprise a forward bracket assembly and a rear bracket assembly. The right carriage rail may comprise a forward truss and a rear truss. The forward truss and the rear truss may comprise members in perpendicular arrangement.
The spar may comprise at least one cushioned roller, at least one truss assembly, and at least one pivot mounting arm. The at least one pivot mounting arm may comprise at least one bracket assembly, an attachment means useful for raising and lowering a watercraft, an electrically-operated actuator, and a loading ramp. The at least one pivot mounting arm may comprise a front pivot arm and a rear pivot arm. The front pivot arm may comprise a first rotation mechanism useful for providing up to 25 degrees range of vertical motion for the carriage structure. The rear pivot arm may comprise a second rotation mechanism useful for providing up to 25 degrees range of vertical motion for the carriage structure. The rear pivot arm may comprise load-bearing materials suitable for carrying a load of the watercraft.
The loading ramp may comprise a ladder structure, which may further may a hinged attacher useful for maneuvering the watercraft to the carriage structure. The ladder structure may also comprise at least one cushioned disk.
The remote activator may comprise system on activation, system off activation, system raise activation, and system lower activation. The remote activator may further comprise RF operating signals.
The blu water lift system may comprise a kit including: the blu water lift assembly, attachment means, and a set of user instructions. A method of using a blu water lift system may comprise the steps of installing front pivot arm and rear pivot arm of a blu water lift system to a boat, loading a watercraft; and unloading a watercraft when desired.
