DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

(8) A preferred embodiment of the present invention is shown in FIGS. 1-7. The vehicle leveler 10, as shown in FIG. 1, includes three primary portions, a first portion 12, a second portion 24 and an extension portion 30 and is designed to be utilized in conjunction with a substantially flat driveway 18 near a loading dock wall 46. Furthermore, the leveler 10 can be moved between a lowered position 36, shown in FIGS. 1 and 3 and a raised position 38, shown in FIGS. 4-6.

(9) First portion 12 has a ramp section 20 which is inclined upwards and a flat section 22 adjacent ramp section 20. First portion 12 includes a leading edge 14 and a trailing edge 16. Trailing edge 16 is disposed further from driveway 18 than leading edge 14. Trailing edge 16 is part of flat section 22. Flat section 22 is disposed about parallel with substantially flat driveway 18.

(10) FIG. 1 illustrates that second portion 24 has a leading edge 26 and a trailing edge 28. Leading edge 26 of second portion 24 is removably attached to trailing edge 16 of first portion 12 as seen in FIGS. 1, 3-4. FIG. 5 illustrates that first portion 12 and second portion 24 are removable attached as it shows first and second portions 12, 24 separated. Leading edge 26 of second portion 24 is disposed further from driveway 18 than trailing edge 28 of second portion 24.

(11) Second portion 24 also includes an extension portion 30 as can be seen in FIGS. 1-7. Extension portion 30 extends from trailing edge 28 of second portion 24 toward a rear of the leveler 10 (nearest the loading dock wall 46) and includes a substantially flat section 32 disposed about parallel with the substantially flat driveway 18.

(12) FIG. 2 illustrates that first 12 and second portions 24 include metal grading 42 over a steel plate for contact with wheels of a vehicle as the vehicle moves onto and off of leveler 10. Metal grating 42 over a steel plate is a material which is both durable and also provides increased traction for vehicles when moving onto or off of leveler 10.

(13) FIGS. 1-7 illustrate that first portion 12 and second portion 24 are each unitary structures which are separate from each other as seen in FIG. 5 until they are removably attached together by a connection apparatus 34 as seen best in FIGS. 1 and 3-4. Connection apparatus 34 is located on leading edge 26 of second portion 24 and connects to trailing edge 16 of first portion 12. Flat section 22 of first portion 12 is in front of connection apparatus 34 since connection apparatus 34 is located on leading edge 26 of second portion 24.

(14) The drawings illustrate that second portion 24 including extension portion 30 can be moved between a lowered position 36 as seen in FIGS. 1, 3 and 7 and a raised position 38 as seen in FIGS. 4-6, to accommodate varying dock heights for loading and unloading of cargo from vehicles. FIGS. 4-7 show a variety of different types of vehicles which can utilize leveler 10.

(15) Depending on the length of the vehicle, leveler 10 can be customized in a variety of ways including that extension portion 30 can consist of multiple extension portions which are identical and which are removably attached together so as to accommodate a vehicle which has a longer length. FIG. 2 illustrates a leveler 10 with more than one extension portion 30. In an embodiment with multiple extension portions 30, each extension portion 30 is removably secured to another extension portion 30. In this type of embodiment, a first extension portion 30 would extend from the trailing edge 28 of second portion 24 toward a rear of leveler 10, the extension portions 30 each would include a substantially flat section 32 disposed about parallel with the substantially flat driveway 18. In some embodiments, the multiple extension portions 30 can be of varying lengths and do not have to be identical in length.

(16) Leveler 10 can be manufactured so that ramp section 20 can be of varying lengths and heights to accommodate a single, rear axle vehicle as well as a large trailer. FIGS. 1 and 6 each illustrate a ramp section 20 with a different length and height. Ramp section 20 and flat section 22 can be manufactured with different lengths and heights to accommodate single rear axle vans and trailers as well as 53-foot over the road tractor trailers. Therefore, leveler 10 can be manufactured so that any of the first portion 12, second portion 24 or extension portion 30, can be of varying lengths and heights so as to accommodate a variety of vehicles types and sizes. For example, FIGS. 3-4 show a box-type truck on leveler 10, FIGS. 5-6 show a larger vehicle on leveler 10 and FIG. 7 illustrates a very large trailer on leveler 10. With leveler 10 it is possible that both the front and rear axles of a vehicle can be elevated to minimize the incline or decline of an inside floor surface 40 of a trailer or vehicle thereby making loading and unloading of cargo safer. FIGS. 3-7 illustrate a variety of vehicles on leveler 10 and the dotted line in FIGS. 3-4 illustrates inside floor surface 40 of the vehicle. FIGS. 4-6 illustrate vehicles on leveler 10 that have both a front and rear axle elevated.

(17) FIG. 6 illustrates that leveler 10 can include opposed sidewalls 52 (see FIG. 2) with a light-mounting channel 44 having at least one light 50 integrated into light-mounting channel 44. Light(s) 50 assist vehicles, such as trailers, when they are backing in or pulling away from leveler 10.

(18) A lifting system is also incorporated into the leveler 10 in the form of hydraulic lifts 48 which contact driveway 18 as seen in FIG. 1. The hydraulic lifts 48 lift the second portion 24 including extension portion 30 of the leveler 10. However, any other lifting systems known in the art could be utilized as well.

(19) Leveler 10 may also include wheel guides 54 shown in FIG. 1 which can be on any or all of first portion 12, second portion 24 or extension portion 30. FIG. 1 illustrates wheel guides 54 on first portion 12. Wheel guides 54 act to guide the wheels of the trailer into the proper position for loading and unloading of cargo.

(20) The relationship between the first portion 12 and the driveway 18 as well as the second portion 24 and the driveway 18 can also be defined in terms of angles as shown in FIGS. 1-7. Ramp section 20 of first portion 12 is inclined from driveway 18 about 1-15 degrees from parallel with driveway 18. Second portion 24 extending from first portion 12 toward a rear of leveler 10 includes a decline section 56 which declines toward the substantially flat driveway at between about 1-15 degrees from parallel with the substantially flat driveway 18.

(21) In operation, a vehicle (including sometimes a large trailer) is backed up to leveler 10 to put the rear wheels onto the first portion 12, specifically ramp section 20. The wheels and trailer are therefore elevated from the driveway 18 as they are backed up onto ramp section 20. As the vehicle is further backed onto leveler 10 the rear wheels pass onto the second portion 24 or decline section 56 and begin to be lowered back toward the driveway 18. As the rear wheels continue to be backed up, they contact the extension portion 30 and at this point, depending on the length and size of the trailer or vehicle, the rear of the trailer or vehicle may now be in contact with the loading dock wall 46. Depending on the length of the vehicle or trailer, the front wheels may either be in contact with the first portion 12 as can been seen in FIGS. 3-4 or the trailer may be so large that only the back wheels are on leveler 10 as seen in FIG. 7. Once though the rear wheels are backed up as far onto the leveler 10 as they can go, the lifting system can then be operated to lift the trailer to the proper height to safely load and unload cargo. Leveler 10 can elevate both the front and rear wheels of a vehicle to minimize the slope of the internal floor of the vehicle which allows for safer loading and unloading.

(22) A wide variety of materials are available for the various parts discussed and illustrated herein. Although the device has been described in conjunction with specific embodiments thereof, it is evident that many alternatives, modifications and variations will be apparent to those skilled in the art. Accordingly, it is intended to embrace all such alternatives, modifications and variations that fall within the spirit and broad scope of the appended claims.
