DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
The following discussion describes in detail at least one embodiment of the present invention. This discussion should not be construed, however, as limiting the present invention to the particular embodiments described herein since practitioners skilled in the art will recognize numerous other embodiments as well. For a definition of the complete scope of the invention the reader is directed to the appended claims. FIGS. 1 through 4 illustrate the present invention wherein a method and apparatus for automatically covering a boat/vehicle/watercraft is disclosed.
Turning to FIGS. 1-4, therein is disclosed the present invention 10 showing a tarp/cover 12 to be used to cover the boat/vehicle 14 which is mounted onto a conventional boat trailer 16 having a frame having first and second end portions and side portions. The trailer 16 has a tongue 18, jack stand 20 with a wheel 22 thereon along with a winch 24 and having a mount 26 for mounting the winch to the front portion of the frame 28 of the trailer 16 wherein the trailer also has a rear end 30 having a pair of wheels 32 for contacting the support surface such as a road wherein the trailer is conventionally towed behind a towing vehicle. Also shown is a U-shaped hoop 34 which is length adjustable at 36 using telescopic members near the distal end portions where the tarp 12 is attached to the hoop. The hoop 34 is constructed of tubular aluminum or like material and the proximate end portions are attached to the sides of the boat trailer 16 at about the middle point of the trailer by means of spring loaded couplers 38 which springs 40 are constantly biased toward the rear of the boat trailer. Means for rotating the tarp bar 42 is provided by electrical means or manual means. When the electric motor 46 is reversed the springs 40 pull the hoop 34 with attached cover 12 toward the rear 30 of the boat 14. Also shown is the tarp bar 42 whereupon the tarp 12 is attached to and rolled upon the tarp bar when in the stored position; the tarp bar is a round piece of aluminum or like material that is suspended proximate the front of the boat 14 and then attached to the trailer 16 by means of frame 44 and the ends of the tarp bar are rotatable in the frame. The tarp bar 42 is disposed in a substantially horizontal plane and is substantially perpendicular to a central axis of the trailer 16. Also shown is a conventional 12 volt electric motor 46 with gear rack 48 and pinion 50 being adapted for connection to the tarp bar 42 so as to turn the tarp bar when the motor is actuated. When the electric motor 46 is actuated it either rolls the tarp bar 46 and the tarp connected thereto in a forward or reverse direction, i.e., clockwise or counterclockwise depending on the direction in which the tarp 12 is rolled onto the tarp bar. If the electric motor 46 is engaged in the forward direction the tarp bar will begin to roll and thus will roll the boat tarp 12 onto the tarp bar. When the electric motor 46 is engaged in the reverse direction the springs 40 in the hoop 34 will begin to unwind the tarp 12 so as to position, i.e., roll out, the tarp over the top of the boat 14 thereby extending the tarp from the front to the rear of the boat so as to cover the boat. Also shown are the steel or like material mounting brackets 52 which attach the coupler 38 for the hoop 34 to the boat trailer which brackets attach to the outside of the trailer frame by using square U-bolts 54. These mounting brackets 52 make the system easy to attach to or remove from the boat trailer 16 thereby eliminating any need to modify an existing boat trailer. The tarp bar 42 and electric motor 46 are located proximate the front of the boat trailer 16 and they are secured to the trailer by aluminum or like material square tubing 56 which is part of frame 44. This tubing 56 allows the tarp bar 42 to be suspended over or near to the nose of the boat 14. These frame and bars 44, 56 also prevent the tarp bar 42 assembly from moving due to the torque produced by the electric motor 46 and the springs 40 in the hoop coupler 38. These support frames 44 are attached to the trailer 16 by the use of mounting bracket 68 using U-bolts 62. Also shown are the motor support 58 and rear bar support 60. When the boat 14 is covered and the distal end or cross member 74 of the hoop 34 is all the way to the rear 30 of the trailer 16 the distal end of the hoop requires support 60, 61 as best seen in FIGS. 1 and 4. Supports 60, 61 have two pieces which extend upwardly from about the middle of the conventional outboard motor support 72 for the lower end of the outboard motor 70. The supports 60, 61 extend upward toward the two corners of the cross member 74 of the hoop 34 and have cradles or rests 76 on the upper end for receiving the cross member 74 therein while the trailer 16 with boat 14 is in transit. Supports 60, 61 keep the cross member 74 secure and in substantially the horizontal plane when the tarp 12 is covering the boat 14.
FIG. 3 shows a typical U-bolt 62 installation showing the U-bolt with nut 64 attaching a typical member 66, such as the mounting bracket 52, 68, to the frame 28 of the trailer as would be done in the standard manner by one skilled in the art.
By way of further explanation, the present invention is a mechanically operated tarp system specifically built for boats/watercraft wherein the system will mechanically roll and unroll the tarp used for covering the boat. The system bolts to the trailer and stays in place when the boat is taken on and off the trailer. After the boat is on the trailer the tarp can be unrolled by pushing a button that controls an electric motor. The system will also be offered in a more economical hand crank model. The entire system will bolt onto the boat's trailer. There will be no welding or special tools required. The system will be wired directly to the boat's electrical system using a waterproof quick disconnect. The mechanical system will be able to be purchased separately. This will allow consumers to use their existing boat tarp. The existing boat tarp will need to be sewn to the mechanical system. Material flaps will be provided in order to attach the existing tarp to the mechanical system. The existing tarps will be sewn to the flaps. This system will allow consumers to quickly and easily protect their boats. It will also allow individuals previously not physically able to take their boat tarp off and on by themselves the ability to do so. The system will be wired directly to the electrical system of the boat using a waterproof quick disconnect.
