Aspects provided relate to a pivoting occupant enclosure door that has an arc of motion in a longitudinal direction of a vehicle.
Recreational and utility vehicles, such as a side-by-side utility vehicle where a driver and a passenger are seated next to each other in a laterally spaced apart seating area, provide an opportunity for carrying the occupants and cargo in locations that may not be as conducive to a traditional full-size road vehicle, such as a pickup truck. Because the utility vehicle may be operated on ground conditions that include bumps and turns, an occupant enclosure may be provided that is configurable to allow easy ingress and egress from the occupant space while still being enclosed sufficiently during operation to inhibit an unintentional egress of an occupant.
Aspects hereof relate to a rearwardly-pivoting door having a pivoting arc in the longitudinal direction of a utility vehicle. The door may be pivotally coupled with the vehicle by a hinge assembly at a rear portion of the door and a front portion of the door is slidably engaged in a channel receiver when the door is in a closed position. The hinge assembly and channel receiver resist lateral movement of the door to maintain an occupant within a seating area of the vehicle. One or more securing devices may be utilized to maintain the door in an opened or closed position. The securing device may be mechanical and/or magnetic.
This Summary is provided to introduce a selection of concepts in a simplified form that are further described below in the Detailed Description. This Summary is not intended to identify key features or essential features of the claimed subject matter, nor is it intended to be used as an aid in determining the scope of the claimed subject matter.
Illustrative embodiments of the present invention are described in detail below with reference to the attached drawing figures, which are incorporated by reference herein and wherein:
The subject matter of embodiments of the present invention is described with specificity herein to meet statutory requirements. However, the description itself is not intended to limit the scope of this patent. Rather, the inventors have contemplated that the claimed subject matter might also be embodied in other ways, to include different steps or combinations of steps similar to the ones described in this document, in conjunction with other present or future technologies.
While aspects provided herein refer to a utility vehicle, such as a side-by-side off-road-capable vehicle, it is contemplated that the features provided herein are applicable to other vehicle types, such as golf carts, lawn mowers, watercraft, agricultural equipment, and the like. Further, a utility vehicle may be referred to as an all-terrain vehicle (ATV) and/or a UTV, in some examples. Therefore, reference to a particular vehicle type is not limiting as to the scope of the concepts provided herein.
Aspects hereof relate to a rearwardly-pivoting door having a pivoting arc in the longitudinal direction of a utility vehicle. The door may be pivotally coupled with the vehicle by a hinge assembly at a rear portion of the door and a front portion of the door is slidably engaged in a channel receiver when the door is in a closed position. The hinge assembly and channel receiver resist lateral movement of the door to maintain an occupant within a seating area of the vehicle. One or more securing devices may be utilized to maintain the door in an opened or closed position. The securing device may be mechanical and/or magnetic.
A first exemplary embodiment provides for a utility vehicle comprising a frame extending in a longitudinal direction from a front end to a rear end; a plurality of wheels operably coupled to the frame; a seating area; and a side door pivotally mounted to the vehicle having a rearward pivotal arc extending in the longitudinal direction of the frame.
A second exemplary embodiment provides for a utility vehicle comprising: a frame extending in a generally longitudinal direction; a plurality of wheels operably coupled to the frame; a seating area at a first longitudinal position relative to the frame; a roll cage enclosing the seating area, and defined by a plurality of frame members coupled to the frame, at least some of the frame members being in the form of frame uprights, and the frame members defining an envelope around the seating area; and a side door pivotally coupled to a first frame upright of the frame uprights and being slidably secured proximate to a second frame upright of the frame uprights, the side door having a pivotable arc extending in the longitudinal direction of the vehicle between a closed position and an open position.
A third exemplary embodiment provides for a side door of a side-by-side utility vehicle having a roll cage, the side door having a pivotable arc in a longitudinal direction of the utility vehicle, the side door comprising: a frame, the frame having a front end and a rear end, the frame having a top edge and a bottom edge, the top edge and the bottom edge extending between the front end and the rear end, a distance between the top edge and the bottom edge at the rear end is greater than a distance between the top edge and the bottom edge at the front end; and a hinge assembly, the hinge assembly coupled with the frame proximate the bottom edge at the rear end, the hinge assembly extending laterally from the frame relative to a longitudinal direction of the bottom edge between the front end and the rear end, the hinge comprised of a hinge sleeve and a pin, the pin extending through the frame and the hinge sleeve, wherein the hinge sleeve is configured to at least partially extend through the roll cage, the hinge assembly is configured to pivotally couple the side door with the utility vehicle to allow a pivot arc in the longitudinal direction of the utility vehicle.
Different areas of the utility vehicle 10 may be generally provided along the general longitudinal length of the vehicle. A seating area 18 is provided between a cargo area 22 at the rear 12 and a hood area 20 at the front 14. The seating area 18 includes at least the portion of the vehicle from which an operator operates/drives the utility vehicle. Additional passengers may also be maintained in the seating area 18, in exemplary aspects. In this example, the seating area 18 is depicted as a single lateral row; however, it is contemplated that two or more rows of seating may be implemented in aspects hereof. For example, it is contemplated that a separate longitudinally-pivoting side door could be provided for each row. Further, it is contemplated that a single longitudinally-pivoting side door could be provided for multiple rows of seating. Also, while a bench-like seating arrangement is depicted, it is contemplated that other seating options may be implemented, such as bucket-style seating, in exemplary aspects.
The cargo area 22 is rearward of the seating area 18. The cargo area 22 is depicted as a cargo bed; however, it is contemplated that a cargo rack or no specific structure is provided rearward of the seating area 18. The hood area 20 is forward of the seating area 18. The hood area 20 may include storage, electrical components, hydraulic components, and/or drive-train components. It is contemplated that one or more portions of the drive train are maintained within or below the cargo area 22, the seating area 18, and/or the hood area 20, in exemplary aspects.
A roll cage 200, or sometimes referred to as a roll-over protection system (ROPS), is provided with the utility vehicle 10. The roll cage 200 is provided to protect and enclose at least a portion of the seating area 18. The roll cage 200 provides a protective canopy to the seating area 18 in the provided illustrations. The roll cage 200 is comprised of a rear upright frame member 202, a longitudinal frame member 206, and a front upright member 204 on a first side. It is contemplated that corresponding frame members are provided on another side of the utility vehicle (not shown). Both sides of the roll cage 200 are interconnected by one or more traverse members extending in a lateral direction between the sides of the roll cage. The roll cage 200 may be removably coupled or permanently coupled with the utility vehicle, such as the utility vehicle frame 24, in an exemplary aspect.
It is contemplated that multiple sections of a roll cage may be integrally connected to accommodate additional seating configurations. For example, if a second row of side-by-side seating was implemented behind a first seating area, the roll cage may include additional upright, longitudinal, and traverse members to form an integrally formed protection canopy around the various seating areas, in an exemplary aspect. As such, it is contemplated that a longitudinally-pivoting side door may be pivotally coupled to any member of the roll cage construction, such as an upright proximate a seat back for each of the seating areas enclosed by the roll cage, in an exemplary aspect.
The longitudinal arc 106 is provided for illustration purposes to demonstrate the door 100 transitioning from a closed position in
The receiving channel may be a U-shaped cavity with an upright ingress and egress portion for the door 100 to slidably be received within the cavity. For example, as the door 100 is pivoted about hinge assembly 102 to close the door 100, a forward portion of the door 100 may slide within the U-shaped cavity of the channel receiver 104 when in the closed position. It is further contemplated that the channel receiver 104 may be comprised of a floor structure between the laterally offset walls such that the floor is effective to support the door 100 at a closed position and to resist further downward rotation of the door 100 past a preferred closed position. It is contemplated that the floor portion of the channel receiver 104 in combination with a motion limit bracket may support and releasably secure the door 100 in a closed position, in accordance with aspects hereof. The floor portion may be integrally formed in a body panel or supplementally incorporated thereafter. Further, it is contemplated that one or more vibration dampening materials (e.g., rubber, foam) may be included within the receiver channel, such as at the floor structure, to resist vibrational noise and effective for dampening a stoppage of a closing rotation within the channel receiver, in an exemplary aspect.
The channel receiver 104 and/or the door 100 may be comprised of one or more releasable securing elements to maintain the door 100 in a closed position when desired. For example, a mechanical lock, clasp, buckle and the like may secure the door 100 within the channel receiver 104 when closed. Additionally or alternatively, it is contemplated that one or more magnetic elements may be implemented to provide an attractive force between the door and the utility vehicle 10 to maintain a closed position. For example, 5-30 pounds of force may be exerted by magnetic attraction to maintain the door 100 in a closed position within the channel receiver 104. In a specific aspect, 10-20 pounds of magnetic force may be used to releasably secure the door 100 in a closed (or open) position. It is contemplated that neodymium rare earth magnets may be permanently secured to at least one of the door 100 and/or the channel receiver 104 that is/are attracted to additional magnetic elements and or magnetic-responsive materials (e.g., ferrous materials) to achieve the desired magnetic attraction force. As will be discussed hereinafter, additionally or alternatively, configuration for a releasable coupling between the door 100 and the utility vehicle 10 may be provided to maintain the door 100 in an open and/or closed position, such as in connection with a motion limit bracket depicted hereafter at
When in a closed position as depicted at
A longitudinally-pivoting door is a door that pivots about an axis such that a longitudinal length of the door (e.g., front to back in the closed position) remains in general alignment with the longitudinal direction of the vehicle as it pivots between an opened and closed position. In some embodiments, the door 100 may be optionally secured to the ROPS or frame or may otherwise be biased in the open position such that the door 100 does not unintentionally swing closed. A longitudinally-pivoting door may be contrasted with a traditional automotive door that transitions from having a longitudinal length that is generally aligned with the automotive vehicle's longitudinal length in the closed position to traverse (or even perpendicular) in an opened position (e.g., the door swing out from a vehicle's midline). In an example, a longitudinally-pivoting door has a longitudinal orientation that changes from near horizontal in a closed position to near vertical when pivoted into an open position, in an exemplary aspect. A longitudinally-pivoting door may also be contrasted to a winged door (e.g., gullwing door) that pivots about an axis generally aligned with the longitudinal direction of the vehicle. A longitudinally-pivoting door pivots about an axis that is generally perpendicular to the vehicle longitudinal axis, in an exemplary aspect. It is contemplated that lines and portions of a vehicle are not rectangular or perpendicular and therefore and portions for ergonomic, style, and aerodynamic purposes will cause one or more lines, axis, and planes to deviate from a square relationship and for that reason, relationships to the longitudinal direction are intended to be general in nature and not limiting to precise parallel and perpendicular interpretations. For example, if the rear upright frame 202 extends toward a midline of the vehicle to provide a tapered roll cage, if the door 100 is pivotally mounted to the inclined rear upright frame 202, when the door 100 pivots, the arc will be in the general direction of the vehicle's longitudinal axis, but it may deviate based on the angled attachment point. However, even with this deviation, the door is still a longitudinally-pivoting door, in this example.
The hinge assembly 102 may extend through the frame 113 at, or near, the intersection of member 112 and 110, such as near (e.g., proximate) the bottom edge of the door 100 towards the rear. As will be depicted in
The rearward opening of the door 100 provides a number of advantages. For example, a rearward opening longitudinal pivoting door does not limit visibility when the door is open as would a forward opening longitudinal pivoting door. Additionally, a rearward opening longitudinal door is maintained in a closed position with a sudden deceleration (e.g., braking) of the vehicle that is traveling in the traditional forward direction. Therefore, the arrangement of a hinge assembly behind a center of mass for the door 100 allows the door to more easily self-secure during a sudden deceleration than a forward opening door.
The panel 126 may be formed from any material, such as plastic, metal, or organic materials (e.g., cellulose based materials). The panel 126 may be solid or include apertures. For example the panel may be formed from a netting material or other cross-hatch like configuration of flexible or rigid materials. Similarly, the panel 126 may be a solid metallic panel, a metallic panel with one or more apertures extending there through, or a decorative panel with internal structural reinforcements. Further yet, it is contemplated that the panel 126 may be formed from one or more molded plastic (e.g., polymer-based materials), such as a blow molded, injection molded, or rotationally molded polymer panel. In light of the previous discussion of an internal door frame, it is contemplated that the panel 126 and the frame are integral and indistinguishable in an exemplary aspect. In a further exemplary aspect, it is contemplated that a polymer door is formed with a self-supporting structure such that a supplemental frame is omitted. The polymer door may have one or more hinge portions integrated during the molding operation or as a post-processes application. For example, a bearing, pin, or other component may be integrally coupled with the polymer during or after the manufacturing of the door, in an exemplary aspect.
As depicted in
The motion limit bracket 128 limits the range of motion for the door 100, in an exemplary aspect. The motion limit bracket 128 may engage with the utility vehicle when the door is in the open, closed, and/or transitional positions. For example, it is contemplated that the motion limit bracket prevents the door from extending beyond a near vertical position when the door is in the open configuration. Similarly, it is contemplated that the motion limit bracket 128 engages the utility vehicle, such as the roll cage, to prevent the door from pivoting beyond an intended closed position.
Further, as previously discussed with respect to the channel receiver 104 of
It is contemplated that the motion limit bracket 128 extends laterally from the door 100 in a common direction as the hinge assembly 102 also extends from the door 100. The motion bracket 128 may extend laterally any amount, such as 0.5 inches to 6 inches, in an exemplary aspect. The motion limit bracket 128 may be constructed from any material, such as a polymer-based material or a metallic-based material. The motion limit-bracket 128 may be secured to the door 100 using any coupling technique, such a mechanical fasteners (e.g., bolts, rivets, screws), adhesives, and/or welding.
Turning to
The hinge assembly 102 of
The hinge assembly 102 is also comprised of the pin 306. The pin 306 may extend through and from a first end to a second end of the hinge sleeves and be rotationally supported by the bearings 312 and 318. The rotational support within the hinge sleeves allows the pin 306 to rotate within the hinge sleeves with a load, such as the door 100, applied to the hinge assembly 102. In an exemplary aspect, a first end of the pin 306 passes through a washer 320 at a flange 316 of the first hinge sleeve 302. The pin 306 continues past the washer 320 and extends through a radius filler 322 and a castle nut 324. The portion of the pin 306 distal the washer 320 extends to and into the door 100, in an exemplary aspect. For example, the door 100 may be formed from a round tube frame by the radius filler 322, the round tube having an inner radius corresponding to the radius filler 322 radius. Therefore, a force applied to the round tube frame is evenly distributed by the hinge assembly 102 internally to the frame, in an exemplary aspect. The pin 306 may include a securing hole 326, such as a hole for a cotter pin or safety wire. The securing hole 306 may be used to maintain the castle nut 324 in a desire position relative to the pin 306, in an exemplary aspect. It is understood that alternative securing mechanisms may be implemented in addition to or alternative to the castle nut 324.
At the second end of the pin 306 extending through the second hinge sleeve 304 at a flange 314 housing the bearing 312 is another washer 320 and a castle nut 308. It is contemplated that the hinge sleeves between the first flange 316 and the second flange 314 extend through a portion of the utility vehicle, such as a portion of the roll cage. In an exemplary aspect the hinge sleeve between the flanges 316 and 314 passes through the rear upright frame member 202 of
The nesting relationship of the second hinge sleeve 304 within the first hinge sleeve 302 may allow for easy installation through one or more portions of the utility vehicle that may vary in thickness or other dimension. The castle nuts 308 and 324 may be tightened to secure the hinge assembly and door to the utility vehicle.
