The present invention relates generally to the field of boating equipment. More specifically, the present invention is an apparatus for a twin arm gin pole with winch.
The trailer-able sailboats manufactured since the late 1960's are designed to have the deck stepped mast rather than the keel stepped mast still used on the larger boats. The deck stepped mast uses the tabernacle base to secure the mast to the deck. There is a compression post built into the boat between the deck and the keel. The tabernacle base allows the mast to be levered up into position rather than the need for a crane to set the mast.
The deck stepped mast with the tabernacle has become popular with the weekend sailor who is required to raise and lower the mast every time they use the boat. Usually short-handed or using a make-shift gin pole the effort involved in handling the mast discourages them from using the boat. The present invention will be a welcomed relief and allow them the sailing freedom they wished for. The present invention allows for one person to handle the winch while a second person keeps track of snags and attaches the final shackle. The objective of the present invention is to stabilize the mast while being raised and lowered preventing the typical sway of an ordinary gin pole or preventing the more dangerous side-to-side movement of a mast swing, both of which could threatens the mast and tabernacle base. The present invention will also eliminate the use of the main sheet block and tackle, which has a tendency to tangle and miss-align the rope feed.
All illustrations of the drawings are for the purpose of describing selected versions of the present invention and are not intended to limit the scope of the present invention.
As can be seen in
The general configuration of components allows the present invention simplifies the process of raising or lowering a deck stepped mast 101. The first arm 1 is orientated at an acute angle with the second arm 2, which creates a V-shaped structural body for the present invention. The first arm 1 and the second arm 2 each comprise a proximal end 3 and a distal end 4. The proximal end 3 of the first arm 1 is connected to the proximal end 3 of the second arm 2, which forms the vertex of the V-shaped structural body. The distal end 4 of the first arm 1 is adjacently and hingedly connected to the first lifeline stanchion coupler 5, which is mounted onto the lifeline stanchion structure. Similarly, the distal end 4 of the second arm 2 is adjacently and hingedly connected to the second lifeline stanchion structure, which is mounted onto the lifeline stanchion structure. The first lifeline stanchion coupler 5 and the second lifeline stanchion coupler 6 are positioned opposite to each other across the deck 102 of the sail boat. The winch 7 is adjacently connected to the distal end 4 of both the first arm 1 and the second arm 2, which allows the winch 7 to apply the maximum amount of torque on the first arm 1 and the second arm 2 as they respectively rotate about the hinged connections of the first lifeline stanchion coupler 5 and the second lifeline stanchion coupler 6. In addition, the halyard connector 11 is adjacently connected to the distal end 4 of the both the first arm 1 and the second arm 2, opposite to winch 7. Consequently, the first arm 1 and the second arm 2 can apply the maximum amount of torque on the deck stepped mast 101 through the halyard line 100 as the deck stepped mast 101 pivots about its other end.
In the preferred embodiment of the present invention, components with certain specifications are better suited to be used in the present invention. The first lifeline stanchion coupler 5 and the second lifeline stanchion coupler 6 are a pair of twisted D-shackles, each of which have a hinged connection with its respective arm through a stainless pin. The winch 7 is a 1500-pound brake winch, which locks in place when the winch 7 is not being cranked by a user in either direction. The first arm 1 and the second arm 2 are a pair of aluminum rectangular tubes, which allows the first arm 1 and the second arm 2 to be lightweight, easily maneuverable, and non-corrodible. Each aluminum rectangular tube is dimensioned at 1.5 inches by 1 inch by 7 feet. The halyard connector 11 is a stainless steel ring, which a simple coupling device for the halyard line 100.
Also in the preferred embodiment of the present invention, the winch 7 specifically comprises a crank axle 8, a strap 9, and a cleat coupler 10. The strap 9 is used to pull the first arm 1 and the second arm 2 in either a clockwise or counterclockwise direction. The strap 9 is wrapped and unraveled from the crank axle 8. The width of the strap 9 should be at 2 inches. The first end of the strap 9 is fixed to the crank axle 8, and the second end of the strap 9 is fixed to the cleat coupler 10, which is used to attach the strap 9 to an available cleat 104 with a backing plate on the deck 102. The cleat coupler 10 can be, but is not limited to, a hook.
A storage hook 12 is an ancillary component of the present invention that allows for a headstay or a fuller to be held by the present invention and allows for the headstay or the fuller to be guided into its proper position as the deck stepped mast 101 is raised or lowered. The storage is hook is laterally connected to either the first arm 1 or the second arm 2 in between the proximal end 3 and the distal end 4 of either the first arm 1 or the second arm 2. The storage hook 12 is designed to be coplanar to the first arm 1 and the second arm 2 so that the headstay or the fuller rests parallel to the deck 102 on the storage hook 12.
The present invention is designed to complete two processes, which are shown in
Although the invention has been explained in relation to its preferred embodiment, it is to be understood that many other possible modifications and variations can be made without departing from the spirit and scope of the invention as hereinafter claimed.
