Description
VEHICLE MOUNTED LIFT
BACKGROUND OF THE INVENTION
1. Field of Invention The present invention relates to vehicle transportation in general and in particular to an apparatus for transporting small vehicles within the bed of a truck.
BACKGROUND OF THE INVENTION
1. Field of Invention The present invention relates to vehicle transportation in general and in particular to an apparatus for transporting small vehicles within the bed of a truck.
2. Description of Related Art The use of recreational type vehicles is a common and enjoyable pastime.
Such recreational type vehicles may comprise all terrain vehicles (ATVs) snowmobiles and the like. It is well known that the use of such vehicles is not permitted in residential neighborhoods where many users live. Therefore it is frequently necessary to transport such vehicles to a location where they can be safely used in compliance with local regulations.
ATVs are typically transported with the use of pick-up trucks either in the bed of the truck or on a trailer towed therebehind. Such trailers are often not practical due to the difficulty of towing such a trailer through difficult terrain or being required to turn the truck and trailer around in a relatively tight space.
It is common for users to wish to transport two ATVs at the same time so that more than one person may participate in this activity at the same time.
Present difficulties exist with current devices for transporting two ATVs on pick-up trucks. Such devices commonly include ATV carrier racks comprising a platform supported above the box of the pick-up truck. Such platforms are commonly designed to carry the ATVs either side by side or one behind the other therein and are therefore commonly substantially wider than the pick-up truck itself. This increased width due to the AN carrier makes navigating the pick-up more difficult. Additionally, having both ATVs supported at an elevated height above the box of the pick-up truck increases the center of gravity of the truck.
Previous attempts to solve the above difficulties have not been adequate. In particular, some previous solutions have provided an elevated rotatable platform supported above the bed of a truck which may be angled to load a top ATV and then raised to permit storage of a second AN thereunder. An example of such devices is disclosed in U.S. Patent Application Publication No. 2008/0014068 to Smith. A disadvantage of such rotating platforms is that the topmost ATV is required to be loaded onto an angled platform. This can be dangerous and difficult due to the need to stop and stabilize the ATV on the angled platform before securing it thereto and thereafter raisin the top platform.

DETAILED DESCRIPTION
Referring to Figure 1, an apparatus for supporting small vehicles according to a first embodiment of the invention is shown generally at 10 located in the bed 6 of a pick-up truck 8. As described herein small vehicles include all terrain vehicles (ATVs), snowmobiles as well as any other recreational-type vehicle which may be transported by a pick-up truck. For reference, such vehicles as utilized herein are referred to as ATVs. Although the present description refers to supporting ATVs, it will be appreciated that the apparatus 10 may also be utilized to support and carry a wide variety of objects, such as, by way of non-limiting example, equipment and building materials. In the case of building materials, it will be appreciated that the platform 30 may be located at a height sufficient to permit any building materials located thereon to pass over the top of the cab of the pick-up to facilitate carrying of long materials such as lumber and the like. As illustrated the apparatus 10 is secured to the bed 6 of a pick-up truck 8 within the box 4 thereof although it will be appreciated that the apparatus may also be secured to the bed of other types of vehicles such as by way of non-limiting example flat deck trucks. The apparatus comprises a frame 12 supporting a vertically movable platform 30 supported by the frame and an actuator for moving the platform between first and second positions.
Turning to Figure 2, a side view of the apparatus 10 is illustrated. The frame 12 comprises a pair of spaced apart front uprights 14 and a pair of spaced apart rear uprights 16. The front uprights 14 are located proximate to the front of the bed 6 of the truck 8 and the rear uprights 16 are located proximate to the rear of the bed of the pick-up truck. The front and rear uprights may further be spaced away from the sides of the bed of the pick-up truck by a distance sufficient to permit the platform to pass between the wheel arches 7 of the pick-up truck. A base member 22 may span bottom portions 18 and 20, respectively, of the front and rear uprights 14 and 16. Each of the front and rear uprights 14 and 16 includes a catch 60 for engaging and supporting the platform to a raised or second position as illustrated in Figure 3. As will be further described below, the catches 60 are selectably releasable so as to permit the platform to be lowered to a bottom or first position as illustrated in Figure 3. The front uprights 14 are connected a top portion 24 thereof by a cross member 26 supporting a winch 50 for raising and lowering the platform 30. The frame 12 may be formed of metal members such as L-channel, c-channels, rods, bars and the like. The members forming the frame 12 may be welded bolted or otherwise connected to each other by any known method.
The frame 12 may be secured to the bed 4 of the truck 8 by any know method such as bolts, buckles, camper tie downs or any other method as are commonly known in the art. It will also be appreciated that the frame 12 may be secured to the stake pockets of the truck 8 by commonly known methods.
The platform 30 comprises a rigid planar member having a rectangular outline defined by a plurality of frame members 32. The platform may be constructed of a space perimeter frame of metal members such as L-channels, c-channel or the like. A deck 34 of plywood or any other ridged decking material so as to provide a surface suitable for supporting an ATV thereon. The platform 30 may be stabilized in an orientation parallel to the bed 4 of the truck 8 by first and second scissor arms, 36 and 38, respectively extending between the platform 30 and the bed 4. The first scissor arm 36 is pivotally connected to the underside of the platform 30 at pivot 40 and extends towards the rear of the apparatus to a free end 46. The free end 46 includes a slider or roller thereon to permit the free end 46 to freely move longitudinally along the bed as the platform 30 is raised and lowered. The second scissor arm 38 is pivotally connected to the base member 22 at pivot 42 and extends towards the rear of the apparatus to a free end 48. The free end 48 includes a slider or roller thereon to permit the free end 48 to freely move longitudinally along the underside of the platform 30 as the platform is raised and lowered. The first and second scissor arms 36 and 38 have substantially equal length and are pivotally connected to each other at a middle portion thereof 44. The first and second scissor arms 36 and 38 serve to maintain the platform 30 parallel to the bed 4 of the truck 8 as it is moved up and down.
The winch 50 may comprise an electric winch as are commonly known in automotive, and recreational vehicles, such as, by way of non-limiting example an ATV winch. Although the winch 50 is illustrated as being located on the cross member 26 at a position above the platform 30, it will be appreciated that it may also be located at other locations such as beside, on or below the platform wherein the elongate tension members 52 extend between the winch 50 and either the platform 30 or the framel2 so as to provide a lifting force to the platform 30. Accordingly, the winch includes power wires from the electrical system of the truck 8 as well as an on/off switch and up and down controls (not shown) as are commonly known. The winch includes a pair of elongate tensions members 52, such as by way of non-limiting example, a cable, rope or chain extending therefrom to opposed sides of the apparatus 10. Each elongate tension member 52 extends over at least one pulley 54 supported by the cross member 26 and downwardly to the platform 30. Through the use of the pair of elongate tension members 52 and pulleys 54, the winch is therefore able to apply a consistently upwards lift force to the platform for movement between the first and second positions. It will be appreciated that utilizing more than one pulley on the cross member 26 and the platform 30 will enable the winch to lift a greater weight of platform and ATV through the mechanical advantage of the pulleys.
In operation, the platform 30 may be lowered to a first position as illustrated in Figure 2 proximate to the bed 4 of the truck 8 to have a first AN placed thereon. Thereafter the winch 50 may then be utilized to raise the platform 30 and first ATV to a raised or second position as illustrated in Figure 3 position whereby a second ATV may be loaded under the platform 30. It will be appreciated that the present design does not include any components located within the space under the platform 30 where the second ATV is to be located.
Turning now to Figures 4 through 6, each upright 14 and 16 may have a catch 60 for supporting the platform 30 extending through a slot 61 therein. The catch 60 may be a pivoting member 62 having a notch 64 therein to receive a frame member 32 of the platform 30. The notch 64 may be defined by a finger 66 extending towards the frame member 32. The pivoting member 62 may be rotatable about a bolt 67 or other suitable means suspended between a pair of support plates 68 extending from the upright to either side of the slot 61. The pivoting member 62 may have a hook 70 extending from a top portion thereof to receive a retaining spring 72 therein so as to retain the pivoting member 62 in locked position such that the finger 66 is on the same side of the upright as the frame member 32 so as to catch and support the platform 30. A bridging plate 74 may be connected to the notch 64 perpendicularly to the slot 61 so as to prevent the pivoting member 62 from rotating completely through the slot 61. A release spring 76 at a bottom of the pivoting member 62 biases the pivoting member 62 in a direction opposed to the retaining spring 72 so as to remove the finger 66 from the same side of the upright as the platform 30 and thereby to release the platform from the catch 60. Optionally, the uprights 14 and 16 may other ratcheting or selectable support means for selectably supporting the platform 30 at a desired height. It will also be appreciated that winch 50 or other means may include a gear reducer such that the winch 50 is operable to retain the platform 30 at the desired height due to the internal mechanical and electrical resistance of the motor to rotation.
In operation, the platform 30 may be raised above the catch 60 and the retaining spring 72 engaged on the hook 70. Thereafter the platform 30 may be lowered into the second position illustrated in Figure 3 to be supported by the finger 66. To lower the platform 30, it may be raised to disengage the platform 30 from the finger 66 and the retaining spring 72 removed from the hook 70. Thereafter the release spring 76 will retract the finger 66 so as to permit the platform to be lowered to its bottom or first position as illustrated in Figure 2. Additionally, the platform 30 may be located and maintained at a height to be substantially aligned with the top of the box of the pick-up truck by the winch 50. At such a height, a region below the platform in conjunction with a locking tailgate of the pick up truck may form a storage compartment which is secure from theft.
While specific embodiments of the invention have been described and illustrated, such embodiments should be considered illustrative of the invention only and not as limiting the invention as construed in accordance with the accompanying claims.

As described herein small vehicles include all terrain vehicles (ATVs), snowmobiles as well as any other recreational-type vehicle which may be transported by a pick-up truck. For reference, such vehicles as utilized herein are referred to as ATVs. Although the present description refers to supporting ATVs, it will be appreciated that the apparatus 10 may also be utilized to support and carry a wide variety of objects, such as, by way of non-limiting example, equipment and building materials. In the case of building materials, it will be appreciated that the platform 30 may be located at a height sufficient to permit any building materials located thereon to pass over the top of the cab of the pick-up to facilitate carrying of long materials such as lumber and the like. As illustrated the apparatus 10 is secured to the bed 6 of a pick-up truck 8 within the box 4 thereof although it will be appreciated that the apparatus may also be secured to the bed of other types of vehicles such as by way of non-limiting example flat deck trucks. The apparatus comprises a frame 12 supporting a vertically movable platform 30 supported by the frame and an actuator for moving the platform between first and second positions.
Turning to Figure 2, a side view of the apparatus 10 is illustrated. The frame 12 comprises a pair of spaced apart front uprights 14 and a pair of spaced apart rear uprights 16. The front uprights 14 are located proximate to the front of the bed 6 of the truck 8 and the rear uprights 16 are located proximate to the rear of the bed of the pick-up truck. The front and rear uprights may further be spaced away from the sides of the bed of the pick-up truck by a distance sufficient to permit the platform to pass between the wheel arches 7 of the pick-up truck. A base member 22 may span bottom portions 18 and 20, respectively, of the front and rear uprights 14 and 16. Each of the front and rear uprights 14 and 16 includes a catch 60 for engaging and supporting the platform to a raised or second position as illustrated in Figure 3. As will be further described below, the catches 60 are selectably releasable so as to permit the platform to be lowered to a bottom or first position as illustrated in Figure 3. The front uprights 14 are connected a top portion 24 thereof by a cross member 26 supporting a winch 50 for raising and lowering the platform 30. The frame 12 may be formed of metal members such as L-channel, c-channels, rods, bars and the like. The members forming the frame 12 may be welded bolted or otherwise connected to each other by any known method.
The frame 12 may be secured to the bed 4 of the truck 8 by any know method such as bolts, buckles, camper tie downs or any other method as are commonly known in the art. It will also be appreciated that the frame 12 may be secured to the stake pockets of the truck 8 by commonly known methods.
The platform 30 comprises a rigid planar member having a rectangular outline defined by a plurality of frame members 32. The platform may be constructed of a space perimeter frame of metal members such as L-channels, c-channel or the like. A deck 34 of plywood or any other ridged decking material so as to provide a surface suitable for supporting an ATV thereon. The platform 30 may be stabilized in an orientation parallel to the bed 4 of the truck 8 by first and second scissor arms, 36 and 38, respectively extending between the platform 30 and the bed 4. The first scissor arm 36 is pivotally connected to the underside of the platform 30 at pivot 40 and extends towards the rear of the apparatus to a free end 46. The free end 46 includes a slider or roller thereon to permit the free end 46 to freely move longitudinally along the bed as the platform 30 is raised and lowered. The second scissor arm 38 is pivotally connected to the base member 22 at pivot 42 and extends towards the rear of the apparatus to a free end 48. The free end 48 includes a slider or roller thereon to permit the free end 48 to freely move longitudinally along the underside of the platform 30 as the platform is raised and lowered. The first and second scissor arms 36 and 38 have substantially equal length and are pivotally connected to each other at a middle portion thereof 44. The first and second scissor arms 36 and 38 serve to maintain the platform 30 parallel to the bed 4 of the truck 8 as it is moved up and down.
The winch 50 may comprise an electric winch as are commonly known in automotive, and recreational vehicles, such as, by way of non-limiting example an ATV winch. Although the winch 50 is illustrated as being located on the cross member 26 at a position above the platform 30, it will be appreciated that it may also be located at other locations such as beside, on or below the platform wherein the elongate tension members 52 extend between the winch 50 and either the platform 30 or the framel2 so as to provide a lifting force to the platform 30. Accordingly, the winch includes power wires from the electrical system of the truck 8 as well as an on/off switch and up and down controls (not shown) as are commonly known. The winch includes a pair of elongate tensions members 52, such as by way of non-limiting example, a cable, rope or chain extending therefrom to opposed sides of the apparatus 10. Each elongate tension member 52 extends over at least one pulley 54 supported by the cross member 26 and downwardly to the platform 30. Through the use of the pair of elongate tension members 52 and pulleys 54, the winch is therefore able to apply a consistently upwards lift force to the platform for movement between the first and second positions. It will be appreciated that utilizing more than one pulley on the cross member 26 and the platform 30 will enable the winch to lift a greater weight of platform and ATV through the mechanical advantage of the pulleys.
In operation, the platform 30 may be lowered to a first position as illustrated in Figure 2 proximate to the bed 4 of the truck 8 to have a first AN placed thereon. Thereafter the winch 50 may then be utilized to raise the platform 30 and first ATV to a raised or second position as illustrated in Figure 3 position whereby a second ATV may be loaded under the platform 30. It will be appreciated that the present design does not include any components located within the space under the platform 30 where the second ATV is to be located.
Turning now to Figures 4 through 6, each upright 14 and 16 may have a catch 60 for supporting the platform 30 extending through a slot 61 therein. The catch 60 may be a pivoting member 62 having a notch 64 therein to receive a frame member 32 of the platform 30. The notch 64 may be defined by a finger 66 extending towards the frame member 32. The pivoting member 62 may be rotatable about a bolt 67 or other suitable means suspended between a pair of support plates 68 extending from the upright to either side of the slot 61. The pivoting member 62 may have a hook 70 extending from a top portion thereof to receive a retaining spring 72 therein so as to retain the pivoting member 62 in locked position such that the finger 66 is on the same side of the upright as the frame member 32 so as to catch and support the platform 30. A bridging plate 74 may be connected to the notch 64 perpendicularly to the slot 61 so as to prevent the pivoting member 62 from rotating completely through the slot 61. A release spring 76 at a bottom of the pivoting member 62 biases the pivoting member 62 in a direction opposed to the retaining spring 72 so as to remove the finger 66 from the same side of the upright as the platform 30 and thereby to release the platform from the catch 60. Optionally, the uprights 14 and 16 may other ratcheting or selectable support means for selectably supporting the platform 30 at a desired height. It will also be appreciated that winch 50 or other means may include a gear reducer such that the winch 50 is operable to retain the platform 30 at the desired height due to the internal mechanical and electrical resistance of the motor to rotation.
In operation, the platform 30 may be raised above the catch 60 and the retaining spring 72 engaged on the hook 70. Thereafter the platform 30 may be lowered into the second position illustrated in Figure 3 to be supported by the finger 66. To lower the platform 30, it may be raised to disengage the platform 30 from the finger 66 and the retaining spring 72 removed from the hook 70. Thereafter the release spring 76 will retract the finger 66 so as to permit the platform to be lowered to its bottom or first position as illustrated in Figure 2. Additionally, the platform 30 may be located and maintained at a height to be substantially aligned with the top of the box of the pick-up truck by the winch 50. At such a height, a region below the platform in conjunction with a locking tailgate of the pick up truck may form a storage compartment which is secure from theft.
