Boat Motor Flushing System

Abstract

A flushing system for boat motors that allows for single-handed manipulation to remotely position flushing ears onto the intake vents of an outboard boat motor. A water passage tube provides a source of fresh water when flushing or performing maintenance on the motor of a boat stored on a lift. The flushing ears are positioned on the intake valves and are adjusted to form a seal by a gripping handle. A locking device prevents movement of the ears while flushing the motor and can be released to remove the ears once the flushing is complete.

Description

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a boat motor flushing system and more particularly pertains to providing a source of fresh water when flushing or performing maintenance on the motor of a boat stored on a lift in a safe, quick, convenient and economical manner.

2. Description of the Prior Art

The use of flushing systems is known in the prior art. More specifically, flushing systems previously devised and utilized for the purpose of providing a water source for flushing and maintenance are known to consist basically of familiar, expected, and obvious structural configurations, notwithstanding the myriad of designs encompassed by the crowded prior art which has been developed for the fulfillment of countless objectives and requirements.

By way of example, U.S. Pat. No. 5,4234,703 issued Jun. 13, 1995 to Thomas H. Lorenzen discloses an outboard motor flushing system. U.S. Pat. No. 4,246,863 issued Jan. 27, 1981 to John T. Reese discloses a flushing assembly. Lastly, U.S. Pat. No. 7,997,946 issued Aug. 16, 2011 to Dewayne Sirmans discloses a flushing assembly for an outboard motor.

While these devices fulfill their respective, particular objectives and requirements, the aforementioned patents do not describe a boat motor flushing system that allows for single handed manipulation when remotely positioning the flushing ears providing a source of fresh water when flushing or performing maintenance on the motor of a boat stored on a lift. The positioning of the flushing system performed in a safe, quick, convenient and economical manner.

In this respect, the boat motor flushing system according to the present invention substantially departs from the conventional concepts and designs of the prior art, and in doing so provides an apparatus primarily developed for the purpose of providing a source of fresh water when flushing or performing maintenance on the motor of a boat stored on a lift in a safe, quick, convenient and economical manner.

The present invention is safe and easy to use compared to existing flushing assemblies. The user does not have to lean over the water or perch precariously on the back of the boat in order to place the flushing ears over the intake vents on the outboard motor. Nor does the user have to apply force to properly position and seal the ears over the intake vents. The gripping handle and simple design allow for single handled operation. The locking mechanism keeps the ears tight during the flushing operation protecting the engine from damage. It has been shown that properly maintaining the engine by flushing with fresh clean water will extend the life of the motor and having a safe easy system to use for completing the flushing may result in boat operators flushing more often.

Therefore, it can be appreciated that there exists a continuing need for a new and improved boat motor flushing system which can be used for providing a source of fresh water when flushing or performing maintenance on the motor of a boat stored on a lift in a safe, convenient and economical manner. In this regard, the present invention substantially fulfills this need by providing a system which can be easily manipulated, allowing for remote placement of the flushing ears without the use of force and a locking gripping mechanism to maintain the seal provided by the flushing ears over the water intake ports during the flushing operation.

Such components are individually configured and correlated with respect to each other so as to attain the desired objective.

In the broadest sense the system is comprised of a double tube formed with a distal end and a proximal end and having a central extent. The central extent having an 8-shaped configuration with a first tube used for the passage of water and a second tube configured as a locking rod axially reciprocable for the application and release of coupling forces. A set of interior and exterior ears is attached to the distal end of the tube. Each ear having walls and a floor and an open face. The floor of the interior ear is secured to the distal end of the cleaning double tube. The floor of the exterior ear is secured to the distal end of the locking rod distally of the interior ear. The proximal end has a handle formed with a first component and a second component adapted to be gripped by a user and squeezed to move the locking rod proximally and shift the ears toward each other for securement to a motor to be flushed. A fitting is located at the proximal end of the first tube for coupling to a source of cleaning water for movement through the upper tube.

In the preferred embodiment of a boat motor flushing system first provided is a cleaning double tube 24 horizontally oriented and formed of a distal end 26 and a proximal end 28 with a central extent 30 between the proximal end and distal end. The central extent has an 8-shaped configuration with an upper tube 34 and a lower tube 36. The upper tube is hollow for the movement of cleaning water 38 from the proximal end to the distal end. The lower tube is hollow for passage of a locking rod 40 axially reciprocable for the application and release of coupling forces between the cleaning double tube and the vertically placed parallel water intake valves of the boat motor.

A pair of flushing ears is located adjacent to the distal end of the double cleaning tube is comprised of an interior ear 44 and an exterior ear 46. Each ear has four trapezoidal walls 48 and a floor 50 and an open rectangular face. The floor of the interior ear is secured to the distal end of the cleaning double tube. The floor of the exterior ear is secured to the distal end of the locking rod distally of the interior ear. The open rectangular faces of the interior and exterior ears are in facing contact with the water intake vents of the boat motor. The locking rod distally of the lower tube is formed in a generally U-shaped configuration extending around the interior and exterior ears.

A handle 54 is located adjacent to the proximal end of the cleaning tube. The handle has a first component 56 and a second component 58, with a pivot pin 60 joining the first and second components centrally. The first component has an outer end and an inner end pivotally coupled to the cleaning double tube adjacent to the proximal end. The second component has an outer end. The second component has an inner end pivotally coupled to the locking rod. The outer ends of the first and second components are adapted to be gripped by a user and squeezed to move the locking rod proximally and shift the ears toward each other for securement to the water intake vents of the boat motor.

A locking assembly 64 having second teeth 66 in an arc is attached to the first component. The locking assembly has first teeth 68 in an arc pivotally attached to the second component whereby movement of the second teeth into contact with the first teeth will lock the ears locked in sealing contact with the water intake vents of the boat motor.

A fitting 72 is provided at the proximal end of the cleaning double tube for coupling to a source of cleaning water for movement through the upper tube and inner ear. The fitting has a valve 74 to initiate and terminate the flow of water through the cleaning double tube. A D-ring 76 is attached to the cleaning double tube adjacent to the proximal end for storage and transportation.

In the preferred embodiment, the ears are fabricated of an elastomeric material such as plastic or rubber, natural or synthetic and blends thereof. The other components are fabricated of rigid materials such as metal, plastic or composite materials.

In a preferred alternate embodiment shown in FIGS. 8 and 9, the handle 100 is adapted to be gripped by a user and squeezed to move the locking rod proximally using a ratcheting motion to shift the ears toward each other for securement to a motor to be flushed. The handle 100 in the broadest sense comprises a cover, a trigger, a push plate and a locking assembly. The handle is comprised of a first component 112 and a second component 114 adapted to be gripped by a user and squeezed. The first component 112 is a trigger having forward face 116 and a rearward face 118. The second component is formed as a cover having an interior surface 120 and an exterior surface 122.

A pivot pin 170 joins the trigger and the cover above the locking rod 40.

A push plate 130 having a forward face 132, a rearward face 134, an upper portion 136 and a lower portion 138. A first aperture 140 is located in the upper portion of the plate. The locking rod passes through the first aperture. A first resilient member 142 encircles the locking rod adjacent to the rearward face of the push plate and urges the plate forward.

When the handle is gripped and the trigger squeezed, the rearward face of the trigger slidably presses against the lower portion of the forward face of the push plate urging the lower portion of the push plate rearward and engaging the locking rod. As the trigger continues to be squeezed, the push plate pulls the locking rod axially rearward, shifting the exterior ear toward the interior ear for securement to the water intake vents of the boat motor to be flushed.

A locking assembly 150 comprises a retaining tab 152, a post 154, a second resilient member 158 and a notch 160. The post is positioned below and parallel to the locking rod and projects from a vertical plate 156 formed on the interior surface of the cover. The second resilient member 158 encircles the post. The notch 160 is formed in the cleaning double tube above the retaining tab. The retaining tab has an upper retaining end 162, a central section and a lower release end 164. The upper retaining end extends into the notch. The locking rod passes through a second aperture 166 formed in the upper retaining end. The second aperture is adapted to releasably engage the locking rod when retaining tab is in the locked position to prevent forward movement of the locking rod. The post passes through a hole 168 formed in the central section of the retaining tab. The second resilient member pivots the lower release end forward forcing the upper retaining end into the locked position with respect to forward motion. When the lower release end is moved rearward, the upper retaining end disengages the locking rod, compressing the resilient member and pivoting the upper retaining end to a vertical and unlocked position.

As to the manner of usage and operation of the present invention, the same should be apparent from the above description. Accordingly, no further discussion relating to the manner of usage and operation will be provided.

With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of the invention, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the present invention.

Therefore, the foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.
