## Background
BACKGROUND
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.
SUMMARY
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.
The forgoing general description of the illustrative implementations and the following detailed description thereof are merely exemplary aspects of the teachings of this disclosure, and are not restrictive.

FIG. 1 illustrates a running board 100 in a narrow position according to an embodiment of the present disclosure. A running board 100 can include a female component 200, a male component 300, and a position locking device 400 (not shown in FIG. 1). Optionally, the running board 100 can also include a position guiding device 500 (not shown in FIG. 1), a traction mark 600 (not shown in FIG. 1), a stepping pad 700, and traction insert 800. The female component 200 and the male component 300 can be connected by the position locking device 400 and the position guiding device 500. Further, the female component 200 and the male component 300 can include an interlocking mechanism to prevent separation of the female component 200 and the male component 300. The running board 100 is assembled such that the male component 300 can slide with respect to the female component 200, while the position locking device 400 and the position guiding device 500 can lock the male component 300 and the female component 200 in a particular position. As such, a width of the running board 100 can be increased and decreased as necessary. The running board 100 can be in a narrow position, a wide position or an intermediate position. The narrow position makes the running board 100 portable and saves storage space, while the wide position can be used when loading objects into a vehicle.
The male component 300 and the female 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 the traction mark 600, the stepping pad 700, and the traction insert 800 can be provided on the surface of the male component 300 and the female 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 the female component 200 on a first side and the traction insert 800 can be attached along the length of the male component 300 on the first side. The traction mark 600 and the traction insert 800 provide traction on the surface of the female component 200 and the male component 300 respectively preventing slippage when a wheel is rolled on the surface of the female component 200 and the male component 300, or when a person walks on the running board 100. The stepping pad 700 can be attached along the length of the female component 200 on a second side. The stepping pad 700 can be fixed to the female component 200 or the stepping pad 700 can slide along the length of the female component 200. The sliding stepping pad 700 can be used to load heavy objects in a vehicle, while the fixed stepping pad 700 can prevent slipping when stepped on the running board 100.
In the narrow position of the running board 100, the female component 200 completely encloses the male component 300 to form a rectangular box. Further, in the narrow position, the running board 100 is removably fitted with a first end cap 101 and a second end cap 103. The first end cap 101 and the second end cap 103 can cover the female component 200 and the male component 300, when configured in a narrow position. The first end cap 101 and the second end cap 103 have smooth edges. The first end cap 101 is locked in place at a first end of the running board 100 with a first cap lock 102, while the second end cap 103 is locked in place at a second end of the running board 100 with a second cap lock 104. The first cap lock 102 and the second cap lock 104 can be a push clip that engages with holes in the male component 300 to snap the first end cap 101 and the second end cap 103, respectively, in a locked state. The first cap lock 102 and the second cap lock 104 can be pushed to disengage the clip from the holes of the male component 300, thus unlocking the first end cap 101 and the second end cap 103. Alternatively, other locking mechanism can be used to hold the first end cap 101 and the second end cap 103 in place. For example, providing grooves on the female component 200 for snap fitting, clip lock, holes for pin lock, bands, etc.
FIG. 2A is a section view of an exemplary running board 100 when in a narrow position according to an embodiment of the present disclosure. The male component 300 has a hollow rectangular cross-section with two hollow rectangular sections 303 and 304. An edge of the male component 300 can be rounded for smoothness, or appearance purposes. Further, along an external circumference of the male component 300, a male hook 301 is formed. Furthermore, the male component 300 can be attached with the traction insert 800. On the other hand, the female component 200 has a C or a U cross-section having a female hook 201 along an internal circumference.
When the male component 300 is inserted in the female component 200, the female hook 201 and the male hook 301 are separated by a distance Dn. Further, a narrow gap Gn can be maintained between the female hook 201 and an outer edge of the male component 300 to create space for external attachments to female component 200. An external attachment can be the stepping pad 700 as discussed earlier in the disclosure. Furthermore, a gap G2 can be maintained between the male hook 301 and an inner edge of the female component 200 to provide space for attachments required to fix external components such as a stepping pad 700. The gap G2 may be created due to a rounded edge of the female component 200.
FIG. 2B is a section view of an exemplary running board 100 when in a wide position according to an embodiment of the present disclosure. When the male component 300 is slide away from the female component 200, the male hook 301 and the female hook 201 are engaged, thus preventing complete separation of the male component 300 from the female component 200. The gap between the female hook 201 and the outer edge of the male component 300 increases to a wide gap Gw, while the distance between the hook is proximately equal to zero. The engagement of the female hook 201 and the male hook 301 can also serve as a rib in the center of the running board 100 for increased support and structural rigidity, increasing load bearing capacity.
FIG. 3A is an elevation view of an exemplary female component 200 according to an embodiment of the present disclosure. The female component 200 can have a hollow cross-section or a hollow portion such as in a significantly C-shaped cross-section. Further, the C-shaped cross-section of the female component 200 can include a first hook surface 205 on a first side and a first traction surface 210 on a second side. The first hook surface 205 and the first traction surface 210 can be of a width Wf. The first hook surface 205 and the first traction surface 210 can be separated by a height Hf. The first hook surface 205 on the first side (bottom side in FIG. 3A) of the female component 200 includes a female hook 201. The female hook 201 can be turned inwards, i.e., towards a hollow portion of the C-shape, at an open end of the female component 200. The female hook 201 can be inclined, or parallel to the first hook surface 205. The gap between the female hook 201 and the first hook surface 205 must be sufficient enough to engage with the male hook 301 of the male component 300. Further, the female component 200 has a first curved edge 225 at the closed end for smoothness. A second side of the female component 200 includes a first projection 220 significantly perpendicular to the first traction surface 210. The first projection 220 can prevent objects from sliding off the female component 200 while loading objects, for example, a dolly with wheels carrying a box.
FIG. 3B is a perspective view of an exemplary female component 200 according to an embodiment of the present disclosure. The female component 200 can be of length Lf. The first traction surface 210 includes a plurality of traction marks such as traction mark 600. The traction mark 600 can be of different shapes and forms such as slots, holes, rough surface, or a combination of thereof. The female hook 201 extends along the length Lf of the female component 200. Alternatively, the female hook 201 can extend partially along the length Lf of the female component 200. For instance, the female hook 201 can be formed at the first end, at the second end, in the middle of the female component 200, or a combination thereof.
FIG. 4A is an elevation view of an exemplary male component 300 according to an embodiment of the present disclosure. The male component 300 has a significantly rectangular cross-section with a second hook surface 305 on the first side and a second traction surface 310 on the second side. The rectangular cross-section can be further divided into a plurality of rectangular sections for increased structural strength and load bearing capacity. For example, the male component 300 includes two rectangular sections 303 and 304. The rectangular sections 303 and 304 can be formed along the entire length of the male component 300 or partially at the ends of the male component 300.
The male component 300 can be of a width Wm and height Hm. The width Wm of the male component 300 is greater than or equal to the width Wf of the female component 200 and height Hm of the male component 300 is smaller than the height Hf of the female component 200, as such allowing the rectangular cross-section of the male component 300 to be fitted within the C cross-section of the female component 200.
The second hook surface 305 on the first side (bottom side in FIG. 4A) of the male component 300 includes a male hook 301, which projects outside the rectangular section 303 and bends away from the hollow rectangular section 303. The male hook 301 can be inclined, or parallel to the second hook surface 305. The gap between the male hook 301 and the second hook surface 305 must be sufficient enough to engage with the female hook 201 of the female component 200. Further, the male component 300 has a second curved edge 325 that extends slightly beyond the second hook surface 305. The second side of the male component 300 includes a second projection 320 significantly perpendicular to the second traction surface 310. The second projection 320 can prevent objects from sliding off the male component 300 while loading objects, for example, a dolly with wheels carrying a box or a wheel chair.
FIG. 4B is a perspective view of an exemplary male component 300 according to an embodiment of the present disclosure. The male component 300 can be of length Lm, which can be significantly equal to the length Lf of the female component 200. The second traction surface 310 can include holes or slots for attachments such as the traction insert 800 (not shown). The male hook 301 extends along the length Lm of the male component 300. Alternatively, the male hook 301 can extend partially along the length Lm of the male component 300. For instance, the male hook 301 can be at a first end, at a second end, in the middle, or a combination thereof. Further, along the second projection 320 one or more holes or slots can be created for various purposes such as viewing the hollow section of the male component 300, adding attachments, etc.
FIG. 5 is a perspective view of a first end of the running board 100 showing internal details according to an embodiment of the present disclosure. The female component 200 and the male component 300 are connected by a position locking device 400, at the first end of the running board 100. The position locking device 400 includes a plurality of holes (not shown in FIG. 5) and a locking pin 405, which can be spring loaded or manually operable and can rest in a hole of the position locking device 400. The position locking device 400 is fixed to the female component 200 using a first plate 601 and to the male component 300 using the second plate 603. The first plate 601 and the second plate 603 can be fixed using different type of fasteners. For example, screws, rivets, glue, welding, etc. The female component 200 and the male component 300 can be moved relative to each other by pulling out the locking pin 405 from the hole of the position locking device 400. After moving the female component 200 and the male component 300, the locking pin 405 can be placed back in a different hole of the position locking device 400 to lock the female component 200 and the male component 300 in a particular position such as a narrow position, a wide position or an intermediate position. For example, the running board 100 can be locked in a narrow position, when not in use, and mounted or stored on a vehicle in a compact manner. Similarly, when the running board 100 is used to load objects in the vehicle, the running board 100 can be locked in a wide position for stability.
FIG. 6 is a perspective view of a second end of the running board 100 showing internal details according to an embodiment of the present disclosure. At the second end of the running board 100, the female component 200 and the male component 300 can be connected by a position guiding device 500. The position guiding device 500 includes a plurality of holes such as a wide hole 501 and a narrow hole 502, and a spring plunger 505. The position guiding device 500 is fixed to the female component 200 using a third plate 701 and to the male component 300 using the fourth plate 702. The third plate 701 and the fourth plate 702 can be fixed using different fastening methods. For example, screws, rivets, glue, welding, etc. The position guiding device 500 helps maintain a position, corresponding to position of the position locking device 400 at the first end, of the female component 200 with respect to the male component 300 at the second end of the running board 100. Positioning the female component 200 and male component 300 at the first end may not translate into same position at the second end due to the length of the running board 100. As such, the position guiding device 500 can assist in maintaining a uniform width of the running board 100 along the entire length of the running board 100.
The spring plunger 505 can lock the running board 100 in a narrow position, a wide position or an intermediate position, similar to the position locking device 400 discussed with respect to FIGS. 7A-7D. The spring plunger 505 can include a shaft with dome shape at a first end and attached to a spring (not shown) at a second end. The shaft of spring plunger 505 can be move in and out of the plurality of holes in the position guiding device 500 on application of a lateral force on the wide hole 501. The lateral force can be exerted, by the edge of a hole, when the female component 200 and the male component 300 are pulled away or push towards each other, causing the spring plunger 505 to compress the spring (not shown). When the spring plunger 505 is aligned with a hole, the spring pushes the shaft of the spring plunger 505 into the hole. Alternatively, the spring plunger 505 can be similar to the locking pin 405 having a loop to apply longitudinal force on the spring plunger 505 to move the spring plunger 505 in and out of a hole.
The second end of the running board 100 can optionally include a first bracket 704 and a second bracket 706 to support the running board 100 when the second end is placed on the ground and first end is placed on the vehicle creating a ramp for loading of objects in a vehicle. Alternative, the first bracket 704 and the second bracket 706 can be an attachment mechanism to the vehicle. The attachment mechanism can prevent sliding of the running board 100 from the vehicle, when the second end is attached to the vehicle and the first end rests on the ground creating a ramp.
FIGS. 7A-7D illustrate the operation of the position locking device according to an embodiment of the present disclosure. The position locking device 400 can include a plurality of holes such as wide lock holes 401a and 401b, narrow lock holes 402a and 402b, and the locking pin 405. The position locking device 400 can be a telescopic tube made of a plurality of tubes arranged coaxially inside each other. In the present disclosure, the position locking device 400 includes two tubes, a first outer tube 410 and a first inner tube 420. The first outer tube 410 and the first inner tube 420 of the position locking device 400 can be attached to the first plate 601 and the second plate 603 respectively. The first outer tube 410 and the first inner tube 420 can be hollow rectangular tubes. Further, each of the first outer tube 410 and first inner tube 420 can include holes for position locking. For example, the first outer tube 410 can include the wide lock hole 401a and the narrow lock hole 402a corresponding to different positions of the running board 100. Similarly, the first inner tube 420 can include the wide lock hole 401b and the narrow lock hole 402b. In certain embodiment, the first outer tube 410 and the first inner tube 420 can have a circular, square, triangular, C, or other appropriate cross-sections. Further, additional holes may be created for intermediate positions of the running board 100.
FIG. 7A illustrates the narrow position configuration of the position locking device 400. In narrow configuration, the first inner tube 420 is inside the first outer tube 410 and the locking pin 405 is engaged with the narrow lock holes 402a and 402b. The locking pin 405 protrudes from the narrow lock hole 402a to lock the first inner tube 420 inside the first outer tube 410.
FIG. 7B illustrates the locking pin 405 disengaged from the narrow hole. The locking pin 405 can be disengaged by pulling out the locking pin 405 from the narrow lock holes 402a and 402b, which allows the first inner tube 420 to slide freely with respect to the first outer tube 410. FIG. 7C illustrates the locking pin 405 in an intermediate position. The first inner tube 420 can be pulled out of the first outer tube 410, as the locking pin 405 is disengaged from the narrow lock holes 402a and 402b. In the intermediate position, the wide hole 401a on the first outer tube 410 is separated from the wide hole 401b on the first inner tube 420.
FIG. 7D illustrates the wide position configuration of the position locking device 400. In wide configuration, the first inner tube 420 is significantly outside the first outer tube 410 and the locking pin 405 is engaged with the wide lock hole 401a of the first outer tube 410, and the narrow lock hole 402b of the inner tube 420. The locking pin 405 protrudes from the wide lock hole 401a to lock the first inner tube 420, thus restricting the free motion of the first inner tube 420 with respect to the first outer tube 410.
In certain embodiments, one or more the locking pin 405 may be used. Further, the locking pin 405 can be inserted only in the first inner tube 410 and not in the first outer tube 420. The position locking device 400 can be configured to generate a different locking pattern based on locking pin inserted in one or more holes in the first inner tube 410 or the first outer tube 420. For example, the first outer tube 420 can include a single hole such as narrow hole 401a, while the wide locking hole 402a may be omitted. On the other hand, the first inner tube 410 can include both the narrow locking hole 401b and the wide locking hole 402b. To create a narrow position, the locking pin 405 can be inserted through the wide locking hole 402a and the narrow locking hole 401b. On the other hand, to create a wide position, the locking pin 405 can be inserted through the wide locking hole 402a and the wide locking hole 402b. 
FIGS. 8A-8C illustrate the operation of the position guiding device according to an embodiment of the present disclosure. The position guiding device 500 includes a plurality of holes such as a wide hole 501 and a narrow hole 502 and the spring plunger 505. The position guiding device 500 can be a telescopic cylinder having a plurality of tubes, similar to the position locking device 400. In the present disclosure, the position guiding device 500 includes two tubes, an second outer tube 510 and an second inner tube 520.
