A loading and unloading device is disclosed that provides users with a convenient and hands-free way to move a dragster in and out of a trailer and from one location to another. This device comprises a dolly-like device that can be hooked to a dragster. The dolly comprises an arm that can lift the dragster up and remove it from a trailer without causing the dragster to drag on the surface of the trailer. This device also enables users to move the dragster in and out of the trailer without needing the assistance of another individual and without causing damage to the dragster's body or frame, or the trailer.
Specifically, the loading and unloading device comprises a dolly, a winch, and a pulley system. The winch is secured to the dolly, and functions to secure a winch cable to a dragster and pull the dragster in the general direction of the dolly. Furthermore, a pulley system is secured to the dolly for redirecting the winch cable from the winch, and reducing the stress on the winch motor. The dolly can also comprise an arm that is pivotally secured to the dragster and that raises the dragster up to a first position and lowers the dragster down to a second position via the operation of the winch. The dolly can also comprise wheels secured to front and rear axles of the dolly to allow for ease in transportation of the device. Exact dimensions or materials used may vary to suit manufacturing needs and/or user preference.
Referring initially to the drawings, FIGS. 1-3 illustrate a loading and unloading device 100 that provides users with a convenient and hands-free way to move a dragster 120 or other suitable vehicle in and out of a trailer (not shown) and/or for lifting one end of the dragster. The loading and unloading device 100 comprises a dolly 102, a winch 104, and a pulley system 106. The dolly 102 comprises a first end 108 and a second end 110, opposing sides 112, and a middle section 114. Typically, the dolly 102 is an elongated frame structure, but could be any suitable structure as is known in the art. Further, the dolly 102 is typically rectangular in shape, however any other suitable shape can be used as is known in the art without affecting the overall concept of the invention.
The dolly 102 would generally be constructed of aluminum, stainless steel, or carbon fiber, etc., though any other suitable material may be used to manufacture the dolly 102 as is known in the art without affecting the overall concept of the invention. The dolly 102 can also comprise a variety of colors and designs to suit user and manufacturing preference. Further, the dolly 102 is approximately 10 inches long as measured from the first end 108 to the second end 110, and approximately between 20 inches wide as measured from opposing sides 112.
Additionally, the dolly 102 comprises a middle section 114, wherein a winch 104 is typically secured to the middle section 114 (as shown in FIG. 1). However, the winch 104 can be secured to any suitable position on the dolly 102 as is known in the art, as long as the winch 104 can function to secure a winch cable 118 to a dragster 120 and pull the dragster 120 in the general direction of the dolly 102. The winch 104 functions as a typical winch that is known in the art and comprises a winch cable 116, a roller 116 for winding up the winch cable 118, and a motor for turning the roller 116. The winch 104 would be secured to the dolly 102 via welding, fasteners, etc., or any other suitable securing means as is known in the art. Typically, the winch 104 is an electrically powered winch, but can be any suitable type of winch as is known in the art. Further, the winch 104 can be powered by a remote (not shown) and comprises a on/off power switch (not shown).
Furthermore, the dolly 102 comprises a pulley system 106 (or assembly) secured to the second end 110 of the dolly 102 for moving the dragster 120. The pulley system 106 can be secured to any suitable position on the dolly 102. The pulley system 106 functions as a typical pulley system that is known in the art and redirects the winch cable 118 from the winch 104. The pulley system 106 would be secured to the dolly 102 via a pin, etc., or any other suitable securing means as is known in the art that allows the pulley system 106 to rotate about its axis. Thus, the winch cable 118 from the winch 104 is redirected through the pulley system 106 and then secured to the dragster 120 (as shown in FIG. 2). The winch cable 118 would be secured to the dragster 120 via hardware, etc., or any other suitable securing means as is known in the art. Once secured, the winch cable 118 would act to pull the dragster 120 in the general direction of the dolly 102.
Additionally, the dolly 102 comprises an arm 122 that is controlled by the winch 104 and able to pivot up and down (as shown in FIG. 3). Typically, the arm 122 is pivotally secured to the middle section 114 of the dolly 102. However, the arm 122 can be secured to any suitable position on the dolly 102 as is known in the art, as long as the arm 122 can function to lift one end of the dragster 120 up and down. The arm 122 would be secured to the dolly 102 via a pin, fasteners, etc., or any other suitable securing means as is known in the art that allows the arm 122 to pivot up and down. Typically, the arm 122 is secured to the dragster 120 and raises one end of the dragster 120 up to a first position and lowers the same end of the dragster 120 down to a second position via the powered winch 104. The arm 122 is secured to the dragster 120 via a claw-like member 124, or any other suitable securing means as is known in the art. Further, the arm 122 typically comprises a stopper 200. The stopper 200 prevents the arm 122 from over-rotating and allows the dragster 120 to rest at a slight angle in the first (raised) position and allows the dragster 120 to be lowered down to the second position when a user (not shown) stops applying or reverses the winch 104.
Furthermore, the dolly 102 can comprise wheels 126 secured to front and rear axles 128 of the dolly 102. The wheels 126 allow the dolly 102 to move and be easily transported from one place to another. The wheels 126 can also comprise brakes (not shown) that allow the wheels 126 to be locked into place once the device 100 is moved into the desired position, to prevent any further movement. Further, the wheels 126 can turn the dolly 102 by using the dragster's front wheels which pulls the dolly 102 right and/or left.
FIG. 4 illustrates the pulley system of the loading and unloading device 100. As stated supra, the dolly 102 comprises a pulley system 106 secured to the second end 110 of the dolly 102 for moving the dragster 120. The pulley system 106 functions as a typical pulley system that is known in the art and redirects the winch cable 118 from the winch 104. The pulley system 106 would be secured to the dolly 102 via a pin, etc., or any other suitable securing means as is known in the art that allows the pulley system 106 to rotate about its axis. Thus, the winch cable 118 from the winch 104 is redirected through the pulley system 106 and then secured to the dragster 120. The winch cable 118 would be secured to the dragster 120 via hardware, etc., or any other suitable securing means as is known in the art. Once secured, the winch cable 118 would act to pull the dragster 120 in the general direction of the dolly 102.
FIG. 5 illustrates the loading and unloading device 100 in use. In operation, a user (not shown) would choose the color and/or specific design of the loading and unloading device 100 that meets their needs and/or wants. The user would then position (via rolling the device 100 on its wheels) the loading and unloading device 100 near the dragster 120 that is to be loaded/unloaded. Once in the desired position, the user can lock the wheels 126 of the device 100, preventing further movement of the device 100. The user then secures the winch cable 118 to the dragster 120, such that the dragster 120 can be pulled in the general direction of the dolly 102. Once the winch cable 118 is secured to the dragster 120, the user then secures the arm 122 to the dragster 120 as well.
Typically, the arm 122 is secured to the dragster 120 via a claw-like member 124. Once the arm 122 is secured to the dragster 120, the arm 122 pivots the dragster 120 up to a first position and lowers the dragster 120 down to a second position via the powered winch 104. A user would turn on the winch 104 which activates the pulley system 106 to draw the dragster 120 in the direction of the device 100, and which activates the arm 122 to pivot the dragster 120 up to a first position. Further, a stopper 200 on the arm 122 would prevent the arm 122 from over-rotating and allows the dragster 120 to rest at a slight angle in the first position.
Once the dragster 120 is moved to the desired position, the user turns off or reverses the winch 104 (or stops applying the winch 104) which allows the dragster 120 to be lowered down to the second position. The user can then unhook (or detach) the arm 122 and the winch cable 118 from the dragster 120. The user then unlocks the wheels 126 and rolls the loading and unloading device 100 away for storage. Thus, the dragster 120 can be lifted and removed from a trailer without causing damage to the dragster 120 or to the trailer, and without needing the assistance of another individual.
