Definitions
- This application relates generally to improvements to a running board and a loading ramp for a vehicle. More particularly the present disclosure relates to improvements related to width adjustment and multi-functional running board and a loading ramp for a vehicle.
- Modern day utility vehicles such as pickup trucks and SUVs typically carry relatively heavy machinery, construction materials, and/or recreational vehicles such as three-wheel or four-wheel all-terrain vehicles (ATVs), motorcycles, and snowmobiles.
- ATVs three-wheel or four-wheel all-terrain vehicles
- vehicles To load and unload such items, as well as to assist vehicle occupants to enter and exit the elevated passenger compartment or cabin portion of the vehicle, vehicles often utilize one or more entry-assist mechanisms.
- a vehicle is typically fitted with side platforms or a running board that extend lengthwise beneath and alongside the passenger compartment of the vehicle at a position adjacent to the passenger doors in order to provide a convenient step surface.
- Running boards have also been used for the loading and unloading of cargo area.
- Running boards may be used to create a ramp between a road surface and the elevated level of the truck bed or cargo area. Such ramps can be transported within a vehicle, or can be securely clamped or bolted to the vehicle when needed.
- U.S. Pat. No. 7,717,445 B2 a removable side step including two elongate section hinges together is described.
- the hinges render load bearing component structurally weak.
- the removable side step requires a special attachment bracket to connect to the vehicle.
- the removable side step in U.S. Pat. No. 7,717,445 B2 is difficult to fit onto and remove from the brackets.
- the tailgate must be modified for attachment as a ramp. A stepping surface and a ramp surface are the same and no traction is provided, which can be difficult to move medium and large equipment up the ramp.
- a multifunctional running board that can be used as a ramp.
- the running board has single platform, which can be removably attached to a vehicle using a pin, bolt, or knob. Further, the running board includes a storage compartment that can house a ramp or other items.
- the width of the platform cannot be adjusted when used as a ramp and narrow when used as a step. It is always narrow, which may not be ideal for medium and large equipment loading. Further, there are no features to prevent vibration, rattle, and noise.
- a modified tailgate is required for attachment as a ramp.
- U.S. Pat. No. 7,637,518 B2 a utility ramp and running board system are described.
- the utility ramp has two folding portions at the ends.
- the folding portion has an internal mechanism including a spring and two links so that it grips a bracket to attach to the side of the vehicle.
- the folding portions also provide an entry and exit transition for the ramp on the ground and at the tailgate.
- the utility ramp in U.S. Pat. No. 7,637,518 B2 does not have adjustable width. It is always narrow, which is not good for medium and large equipment loading. Further, the folding portions can easily be damaged since they are part of the ramp, which may cause failure of attachment while in use.
- U.S. Pat. No. 7,708,294 B2 a detachable dual use platform apparatus that can be locked to a vehicle with a key. When unlocked, the extrusion can be removed from the brackets and used as a loading ramp.

Abstract
Description
- Field of the Disclosure
- This application relates generally to improvements to a running board and a loading ramp for a vehicle. More particularly the present disclosure relates to improvements related to width adjustment and multi-functional running board and a loading ramp for a vehicle.
- Description of the Related Art
- Modern day utility vehicles such as pickup trucks and SUVs typically carry relatively heavy machinery, construction materials, and/or recreational vehicles such as three-wheel or four-wheel all-terrain vehicles (ATVs), motorcycles, and snowmobiles. To load and unload such items, as well as to assist vehicle occupants to enter and exit the elevated passenger compartment or cabin portion of the vehicle, vehicles often utilize one or more entry-assist mechanisms.
- A vehicle is typically fitted with side platforms or a running board that extend lengthwise beneath and alongside the passenger compartment of the vehicle at a position adjacent to the passenger doors in order to provide a convenient step surface. Running boards have also been used for the loading and unloading of cargo area. Running boards may be used to create a ramp between a road surface and the elevated level of the truck bed or cargo area. Such ramps can be transported within a vehicle, or can be securely clamped or bolted to the vehicle when needed.
- In U.S. Pat. No. 7,717,445 B2, a removable side step including two elongate section hinges together is described. However, the hinges render load bearing component structurally weak. Furthermore, the removable side step requires a special attachment bracket to connect to the vehicle. The removable side step in U.S. Pat. No. 7,717,445 B2 is difficult to fit onto and remove from the brackets. Also, the tailgate must be modified for attachment as a ramp. A stepping surface and a ramp surface are the same and no traction is provided, which can be difficult to move medium and large equipment up the ramp.
- In U.S. Pat. No. 2009/0,044,729 A1, a multifunctional running board that can be used as a ramp is described. The running board has single platform, which can be removably attached to a vehicle using a pin, bolt, or knob. Further, the running board includes a storage compartment that can house a ramp or other items. The width of the platform cannot be adjusted when used as a ramp and narrow when used as a step. It is always narrow, which may not be ideal for medium and large equipment loading. Further, there are no features to prevent vibration, rattle, and noise. A modified tailgate is required for attachment as a ramp.
- In U.S. Pat. No. 7,637,518 B2, a utility ramp and running board system are described. The utility ramp has two folding portions at the ends. The folding portion has an internal mechanism including a spring and two links so that it grips a bracket to attach to the side of the vehicle. The folding portions also provide an entry and exit transition for the ramp on the ground and at the tailgate. The utility ramp in U.S. Pat. No. 7,637,518 B2 does not have adjustable width. It is always narrow, which is not good for medium and large equipment loading. Further, the folding portions can easily be damaged since they are part of the ramp, which may cause failure of attachment while in use.
- In U.S. Pat. No. 7,708,294 B2, a detachable dual use platform apparatus that can be locked to a vehicle with a key. When unlocked, the extrusion can be removed from the brackets and used as a loading ramp. The platform U.S. Pat. No. 7,708,294 B2 does not have an adjustable width.
- A running board that can be easily used as a ramp for loading equipment into the tailgate or another compartment of a vehicle is needed. Further, for loading items of different sizes, the width should be adjustable There remains a continuing need to provide improved running boards having multiple utility and easily adjustable. A ramp with light mass and the high load carrying capacity and an improved strength and performance is needed.
- According to an embodiment of the present disclosure, there is provided a running board apparatus. The running board apparatus includes a first component with a hollow cross-section having an open end extending in a longitudinal direction, a second component with a rectangular cross-section extending in a longitudinal direction and inserted in the first component from the open end, and a positioning device with one end attached to the first component and an opposite end attached to the second component, wherein the positioning device is configured to move the second component with respect to the first component in a lateral direction and lock the second component and the first component in a narrow position or a wide position.

FIG. 1 illustrates a runningboard 100 in a narrow position according to an embodiment of the present disclosure. A runningboard 100 can include afemale component 200, amale component 300, and a position locking device 400 (not shown inFIG. 1 ). Optionally, the runningboard 100 can also include a position guiding device 500 (not shown inFIG. 1 ), a traction mark 600 (not shown inFIG. 1 ), astepping pad 700, andtraction insert 800. Thefemale component 200 and themale component 300 can be connected by theposition locking device 400 and theposition guiding device 500. Further, thefemale component 200 and themale component 300 can include an interlocking mechanism to prevent separation of thefemale component 200 and themale component 300. The runningboard 100 is assembled such that themale component 300 can slide with respect to thefemale component 200, while theposition locking device 400 and theposition guiding device 500 can lock themale component 300 and thefemale component 200 in a particular position. As such, a width of the runningboard 100 can be increased and decreased as necessary. The runningboard 100 can be in a narrow position, a wide position or an intermediate position. The narrow position makes the runningboard 100 portable and saves storage space, while the wide position can be used when loading objects into a vehicle. - The
male component 300 and thefemale component 200 can be a beam having a C cross-section or a U cross-section. Alternatively, other cross-sections such as I cross-section or rectangular cross-section may be used. Furthermore, the cross-section can be hollow or solid. Additionally, different means for attaching thetraction mark 600, thestepping pad 700, and thetraction insert 800 can be provided on the surface of themale component 300 and thefemale component 200. For example, indentations, slots, holes, threaded holes, rough surfaces, locating holes, etc. can be provided. - The
traction mark 600 can be formed along the length of thefemale component 200 on a first side and thetraction insert 800 can be attached along the length of themale component 300 on the first side. Thetraction mark 600 and thetraction insert 800 provide traction on the surface of thefemale component 200 and themale component 300 respectively preventing slippage when a wheel is rolled on the surface of thefemale component 200 and themale component 300, or when a person walks on the runningboard 100. Thestepping pad 700 can be attached along the length of thefemale component 200 on a second side. Thestepping pad 700 can be fixed to thefemale component 200 or thestepping pad 700 can slide along the length of thefemale component 200. The slidingstepping pad 700 can be used to load heavy objects in a vehicle, while the fixedstepping pad 700 can prevent slipping when stepped on the runningboard 100. - In the narrow position of the running
board 100, thefemale component 200 completely encloses themale component 300 to form a rectangular box. Further, in the narrow position, the runningboard 100 is removably fitted with afirst end cap 101 and asecond end cap 103. Thefirst end cap 101 and thesecond end cap 103 can cover thefemale component 200 and themale component 300, when configured in a narrow position.
