Description
- The present application claims the benefit of priority of U.S. Provisional Patent Application No. 62/303,835, filed Mar. 4, 2016, for “Ramp Device for Loading and Unloading Vehicles,” the contents of both application are fully incorporated herein by reference.
- The present disclosure relates to a ramp device that is configured to be used for loading and unloading of vehicular machines such as snowmobiles, all-terrain vehicles (ATV's), utility vehicles (UTV's), motorcycles, snow bikes, golf carts, and utility machines such as riding lawn mowers, from a bed of a truck or a trailer. More particularly, the present disclosure relates to a ramp that is configured to be removably attached to a tailgate or bed while also being configured to be manipulated into a compact configuration for transport and storage.
- Currently, there are many ramps on the market that are designed specifically for a certain type of vehicular machine. The designs of these ramps attempt to facilitate loading with correct traction and glide, while transporting a machine to a different vertical level. Unfortunately, many ramps do not effectively provide adequate machine tire traction, track traction, foot traction, or smooth glide where needed.
- While not ideal, consumers may use an ATV ramp for loading a snowmobile, and consumers may use a snowmobile ramp for loading an ATV, for example, and vice versa. Consumers struggle with cost-effective ways to load their machines and in some cases may compromise their safety in doing so.
- In some instances, users are not using a strap to secure the ramp to the tailgate or bed, which can result in the ramps being ejected off the transport vehicle and injury to the user. Further, in many instances, adequate surfaces for walking on the ramps are not available, especially in power sports ramps. The lack of adequate walking surfaces can result in users falling when loading and unloading the machines.
- In one aspect, a ramp is configured for use with a vehicular machine to allow the vehicular machine to move from a ground surface to an elevated surface of a transport vehicle.

FIG. 1 ,ramp 10 is configured to be used for loading and unloading of avehicular machine 18 such as a snowmobile, ATV, UTV, motorcycle, snow bike, golf cart, riding lawn mower, or other utility or recreational machine, from a bed of a truck or a trailer (e.g., transport vehicle 19).Ramp 10 allows thevehicular machine 18 to move from a ground surface atend 16 to an elevated surface of atransport vehicle 19 atend 14. Anend 14 oframp 10 is configured for removable attachment to atail gate 12, bed, or other portion oftransport vehicle 19. Anopposite end 16 oframp 10 is configured to engage a ground surface. Theramp 10 is configured to withstand the forces imparted through the raising and lowering ofvehicular machine 18 onto and off from thetransport vehicle 19. - Referring to
FIGS. 1 and 2 , theramp 10 includes amiddle portion 20 having left and right spaced apart side rails 22 and 24 that are connected together with a plurality of spaced apart cross bars 26. The cross bars 26 are connected at substantially uniform intervals along a length of the spaced apart side rails 22 and 24. Side rails 22 and 24 are oriented substantially parallel to the length along the longitudinal direction L oframp 10. - The spaced apart side rails 22 and 24 and the plurality of cross bars 26 are typically constructed of a tubular aluminum. Aluminum provides sufficient structural integrity to withstand the forces imparted on the
ramp 10 while loading and unloading devices from the ground surface to the bed and back, while being light in weight, which aids in moving and positioning theramp 10 in selected locations. While aluminum is a typical material of construction, other materials can also be utilized including other metals and/or thermoplastics. - The cross bars 26 have a sufficient width to engage a track of the
snowmobile 18. Cross bars 26 are formed from one-inch aluminum tubing in an exemplary embodiment. To prevent slippage of, and potential damage to,vehicular machine 18, in an exemplary embodiment, the cross bars 26 are at least partially covered with a grip cover ortraction enhancing cover 28. Thetraction enhancing cover 28 typically includes a rough surface that is configured to engage the track ofsnowmobile 18 without slippage, where thetraction enhancing cover 28 is typically a molded polymeric material. Eachtraction enhancing cover 28 is typically secured to anindividual cross bar 28 with a fastener as such a screw or bolt. Advantageously, in such cases, thetraction enhancing cover 28 can be replaced by removing the fastener, installing anew cover 28, and the reinstalling the fastener. Other securing mechanisms are also within the scope of the present disclosure, including but not limited to, a rivet, a snap fit device, and an adhesive. In an exemplary use,traction enhancing cover 28 protects studs of a snowmobile from damage, as well as protects cross bars 26 from damage from such studs. - Referring to

The hinges 34 and 36 transfer a load from the portions left andright track portions middle portion 20 and vice versa to spread the load across theramp 10, which reduces the amount of material required in therails ramp 10. In the open position ofFIGS. 2 and 4 , top surfaces ofleft portion 30,middle portion 20 andright portion 32 all lie in substantially a common plane (e.g., a top surface of theopen ramp 10 is substantially flat). In the closed position ofFIG. 5 , left andright portions respective hinges right portions middle portion 20. - The
left track portion 30 and theright track portion 32 are similarly constructed and are typically substantially mirror images of each other. Eachtrack portion rails ramp 10. Therails cross members 44, as shown inFIG. 3 . Thecross members 44 are typically made of a corrosion-resistant metal material, such as, but not limited to aluminum. The metal material provides sufficient strength to support and guide wheels, tires or skis ofvehicular machines 18 to be used withramp 10. - The area between the spaced apart rails 40 and 42 is substantially covered with a
web 46 that has an array of raisedmembers 48, such as lugs, arranged in rows, such as shown inFIG. 4 . Theweb 46 is supported along longitudinal edges ofrails longitudinal ribs 41. The rows of raisedmembers 48 are spaced apart to define a plurality of longitudinal travel paths orchannels 58 therebetween. Such travel paths orchannels 58 allow carbide(s) of a snowmobile ski to be positioned between adjacent rows of raisedmembers 48 and thereby travel by gliding over a smooth surface. At the same time, the rows of raisedmembers 48 substantially prevent movement in a lateral direction 38 (labeled inFIG. 4 ; substantially perpendicular to the longitudinal direction L of ramp 10). The rows include spaced apart raisedmembers 48 that provide traction to a wheel as thevehicular machine 18 —or traction to a user's shoes as the user —travels up and down on thetrack portions members 48 have a relatively low profile, a person can easily walk on theweb 46 without a likelihood of tripping or slipping. - The
web 46 is typically a polymeric material to provide traction, guidance and wear properties while being light in weight. However, theweb 46 can be constructed from other materials and also can have other upper surface configurations than disclosed herein. In some embodiments, theweb 46 includes slots (not shown) through which fastening mechanisms are secured toribs 41. Moreover, other slots or apertures may be provided inweb 46 to allow precipitation flow and expansion and contraction due to temperature changes, to prevent warpage. - When in the folded configuration of
FIG. 5 , a width of theramp 10 is sufficiently narrow to allow theramp 10 to be stored on a bed oftransport vehicle 19 beneath avehicular machine 18 and between its wheels, tires, or skis. Referring toFIG. 6 , theramp 10 can optionally include one or more slide bars 70 that are located on one or more ofrails ramp 10 on a tail gate or bed oftransport vehicle 19 by reducing friction, and therefore preventing damage to the bed or tail gate as theramp 10 is slid thereon. The slide bars 70 can be located on any or all of therails - Referring to
FIGS. 6 and 7 , theramp 10 includesflexible feet 50 extending from theends 16 of therails flexible feet 50 are fixedly secured to therails Feet 50 provide traction on the ground or loading base of theramp 10. In an exemplary embodiment, eachfoot 50 includes barbs orteeth 52 that are oriented in a direction substantially traverse to a direction of travel ofvehicular machine 18 on the ramp 10 (e.g., a longitudinal direction L of ramp 10). The barbs orteeth 52 allow the feet to equalize pressure across the ground surface or loading base despite different ground conditions, such as but not limited to, snow, grass, dirt and concrete. - Referring to
FIGS. 8 and 9 , end 14 oframp 10 includes bed ortailgate engaging mechanisms 60 fixedly secured to ends of therails mechanisms 60 are configured to be removably secured to the bed or tailgate by the weight of theramp 10 and thevehicular machine 18 being moved on theramp 10. The engagingmechanisms 60 include an inner portion orfinger 61 that optionally includes barbed oruneven surfaces 62. Anoverlay 63 is formed of an elastomeric material and can have an uneven interior surface configured to mechanically interlock with theuneven exterior surface 62 of thefinger 61.Overlay 63 is positioned on the inner portion orfinger 61, wherein the mechanical interlocking of the interfacing surfaces retains theoverlay 63 thereon and prevents theoverlay 63 from slipping off of thefinger 61. - The
finger 61 is typically constructed of a metal, such as aluminum. However, other materials of construction are also contemplated. Theoverlay 63 is typically constructed of a flexible polymer and includes a plurality ofteeth 64 that are configured to engage the bed or tail gate to prevent slippage as a vehicle is moved over theramp 10. The plurality ofteeth 64 are orientated substantially traverse to a direction of travel of the vehicle on the ramp 10 (e.g., longitudinal direction L of ramp 10) to aid in the prevention of slippage ofend 14 from the bed or tailgate oftransport vehicle 19. - Referring to
FIG. 10 , theramp 10 includes a strap 66 that is utilized to attach theramp 10 to the bed or tailgate oftransport vehicle 19. The strap 66 may be fixedly attached to the ramp at an easy-to-locate homing location, such as a plate or bracket, such as at one end of strap 66, while the other end of strap 66 includes a fastening member 67, such as a hook, configured for attachment to another fixed structure, such as a plate or bracket. Alternatively, the strap 66 may have fastening members at each end. Attachment structures for strap 66 are illustrated ontrack portion 32. However, it is to be understood that attachment structures for strap 66 may alternatively or additionally be provided onmiddle portion 20 ortrack portion 30. The strap 66 may include aretraction mechanism 68 —such as a spring loaded reel or a ratcheting reel —that can automatically retract strap 66 intomechanism 68. Alternatively, the strap 66 may include a buckle through which the length of the strap 66 is adjusted. The strap 66 is utilized to retain theramp 10 in a fixed location, to reduce the chance of theramp 10 getting kicked out from, or dislodging from, the tailgate or bed oftransport vehicle 19 as avehicular machine 18 is moved over theramp 10. Additionally, the same or a second strap (not shown) may be utilized to retain theramp 10 in a desired location, such as when in transit. -
