Utility vehicle half door

Abstract

A utility vehicle half door includes a unitary molded plastic body that is symmetrical and identical on both a first surface and second surface. Hinge knuckles are integral with the unitary molded plastic body for hinged mounting to the left or right side of a utility vehicle. An interior panel subassembly with the door release handle and door latch may be attached to one of the first and second surfaces.

Description

FIELD OF THE INVENTION

This invention relates to off-road and recreational utility vehicles, and more specifically to a utility vehicle half door.

BACKGROUND OF THE INVENTION

Utility vehicles for off-road and recreational use are capable of carrying a seated driver and one or more seated passengers. These utility vehicles may include one or two rows of seats, and roll over protection structures extending over the seating areas. Additionally, they may require occupant side retention devices to reduce the probability of entrapment of a properly belted occupant's head, upper torso and limbs in the event of a tip-over onto the vehicle's side. Some off-road and recreational utility vehicles include side nets, as shown in U.S. Pat. Nos. 9,061,569 and 9,073,412. Others may include half doors, such as U.S. Pat. No. 9,789,753 and 10246153. Half doors are more costly than side nets. Half doors also may include more parts such as mounting brackets for door release and latching components. A utility vehicle half door is needed that is low in cost and has few parts.

SUMMARY OF THE INVENTION

A utility vehicle half door may be a one piece plastic body having identical exterior and interior surfaces. A modular interior panel may be mounted to the interior surface. The modular interior panel may include an integral armrest, along with a door release handle, a door latch, first and second linkages between the release handle and door latch, a pivot member between the first and second linkages, and a release spring. A plurality of hinge knuckles on an edge of the one piece plastic body may be used to mount the one piece plastic body to either the left or right side of a utility vehicle.

BRIEF DESCRIPTION OF THE DRAWINGS

FIG. 1 is a side view of a utility vehicle half door mounted to the left side of an off-road or recreational utility vehicle according to a first embodiment of the invention.

FIG. 2 is a side view of the utility vehicle half door of FIG. 1, mounted to the right side of an off-road or recreational utility according to a first embodiment of the invention.

FIG. 3 is an exploded perspective view of the utility vehicle half door of FIGS. 1 and 2 having an interior panel subassembly according to a first embodiment of the invention.

DESCRIPTION OF THE PREFERRED EMBODIMENT

In one embodiment, utility vehicle half door 100 may be a unitary molded plastic body that is symmetric. The first surface 104 and second surface 106 of the unitary plastic body may be identical. The first and second surfaces may be exterior or interior surfaces. As a result, the same utility vehicle half door may be mounted to the left side of an off-road or recreational utility vehicle as shown in FIG. 1, or the right side of the vehicle as shown in FIG. 2.

In one embodiment, utility vehicle half door 100 may include at least two hinge knuckles, such as upper hinge knuckle 108 and lower hinge knuckle 110. Both upper and lower hinge knuckles may be integral with the unitary molded plastic body. Both upper and lower hinge knuckles may be located on the forward edge of the half door, so that the half door may swing out when it is mounted on either side of the vehicle. For example, upper and lower hinge pins 112, 114 may be inserted through the hinge knuckles and through upper and lower sleeves or retainers on the rear edge of front left fender 116 and front right fender 118 of the utility vehicle. Tab 119 may be provided on at least one of the hinges to stop the door from opening more than about 90 degrees. Additionally, the hinge knuckles may be located on the rear edge of the half door, or a second pair of half doors may be provided on a utility vehicle having a second row of seats. The half doors are shown mounted to fenders, but also may be mounted to a post or frame member.

In one embodiment, as shown in FIG. 3, utility vehicle half door 100 may include interior panel subassembly 120. The interior panel subassembly may include interior panel 122 and integrated armrest 124. The interior panel subassembly also may include door release and latching components such as door release handle 126, door latch 129, linkages 130 and 132, pivot member 134, and latch spring 136. Additionally, when the interior panel subassembly is mounted to the utility vehicle half door, cover plate 128 may be attached to the outside surface of the half door to help secure the door latch in position so that it can move rearwardly to engage a latch bolt or rod on the vehicle.

In one embodiment, utility vehicle half door 100 may include modular interior panel subassembly 120. The modular interior panel subassembly, including the door release and latching components listed above, may be assembled to the interior panel before the subassembly is attached to utility vehicle half door 100. Clips or threaded fasteners 138 may be used to attach the interior panel subassembly to the interior surface of the utility vehicle half door. The clips or threaded fasteners may be inserted through the interior panel subassembly and may engage holes in the interior surface of the half door. The interior panel subassembly also may eliminate any need for mounting brackets on a utility vehicle half door for door release or latching components.

Having described the preferred embodiment, it will become apparent that various modifications can be made without departing from the scope of the invention as defined in the accompanying claims.
