TECHNICAL FIELD
[0001] The present invention relates to a hinge for a sliding vehicle door, the hinge having
a first end for being connected to the body side and a second end for being connected
to the door. Further, the first end has a pivot point and the second end also has
a pivot point.
BACKGROUND
[0002] A sliding door is a type of door mounted on or suspended from a track for the door
to slide, usually horizontally. It is a feature predominately used for minibuses and
buses to provide a large entrance or exit for passengers without obstructing the adjacent
pathway between the vehicle and any adjoining object on the side of passenger and
commercial vans. Accordingly, it allows for a larger unobstructed access to the interior
for loading and unloading.
[0003] Sliding doors are often used in mini Multi Purpose Vehicles (MPVs) but are more commonly
used in full-sized MPVs. Their use has increased over the years as MPVs have increased
in popularity, because it gives easy access and makes parking in tight spaces possible.
The most common type of sliding door, that has a three-point suspension and opens
outwards, then runs along the side of the vehicle, was introduced in 1964.
[0004] Most common are vehicles with sliding doors where the track is on the exterior of
the vehicle. There are also sliding doors where the track is on the inside of the
door and on the side of the door itself. This allows the exterior to remain clean
in design and yet the door can slide past the trailing edge of the car. The solutions
with the track on the inside of the door are generally bulky.
SUMMARY
[0005] It is an object of the present invention to provide an alternative solution for a
sliding door on a vehicle with a hinge and hinge system that is relatively light but
at the same time provides stability.
According to a first aspect of the present disclosure a hinge for a sliding vehicle
door has a first end for being connected to the body side and a second end for being
connected to the door. The first end has a pivot point and the second end has a pivot
point. The pivot point of the second end comprises a running element for running along
a rail and wherein the second end further comprises a second running element arranged
at a distance from the running element of the pivot point. The pivot point of the
first end, the pivot point of the second end and the second running element form a
triangle. In use upon turning the hinge about the second end pivot point the second
running element engages with the rail such that the second running element will run
along the rail at a distance from the running element of the pivot point upon sliding
the vehicle door.
[0006] The second end having a running element as well as a pivot point at a distance from
each other provides for a more stable solution when the door is being opened or is
open as compared to only having a pivot point for the door. With this solution it
is not necessary to have a hinge on the top side of the door since the stability of
the two points and a hinge on the lower side of the door is sufficient.
[0007] According to one aspect of the present disclosure the running element of the pivot
point comprises a wheel. Preferably, the wheel is arranged with a bearing, for instance
a ball bearing, in order to minimize the friction.
[0008] According to another aspect of the disclosure, the second running element comprises
a wheel. For the same reason as stated above for the running element of the pivot
point, the wheel is preferably arranged with a bearing, for instance a ball bearing.
[0009] Another aspect of the present disclosure is to provide a hinge system for a sliding
vehicle door comprising a hinge according to the above. The system comprises a rail
engaged with the running element of the second end pivot point of the hinge such that
the running element runs along the rail upon opening or closing the vehicle door.
[0010] According to one aspect the rail of the hinge system is a hollow profile with a recess
along the rail, the width of the recess being larger than the thickness of the hinge
and smaller than the width of the running element. Thus, the running element of the
pivot point is always situated in the hollow profile with the hinge running in the
recess. Upon opening the door the hinge is rotated about the pivot point with the
running element until the second running element engages in the hollow profile. Further
opening of the door will result in the running element of the pivot point as well
as the second running element will move inside the hollow profile and thus the hinge
will not rotate around the pivot point after the second running element has engaged
with the hollow profile.
[0011] According to yet another aspect of the present disclosure, the elongate recess of
the hollow profile has one part with a width larger than the width of the second running
element. Upon opening the vehicle door the second running element will enter into
the hollow profile through this part of the recess with the larger width.
[0012] According to an alternative aspect of the hinge system the rail is T-shaped. Thus,
with this solution the running elements will move on the outside of the rail rather
than inside as is the case with the hollow profile as rail.
[0013] Similarly as with the hollow profile rail, according to a further aspect the T-shaped
rail has one part that is I-shaped. Upon opening the vehicle door the second running
element will be moved onto the T-shaped rail at the part of the rail missing the flanges
of the T-shape, i.e. at the part of the rail that is I-shaped.
[0014] Further features of, and advantages with, the present invention will become apparent
when studying the appended claims and the following description. The skilled person
realize that different features of the present invention may be combined to create
embodiments other than those described in the following, without departing from the
scope of the present invention.

DETAILED DESCRIPTION OF EXAMPLE EMBODIMENTS OF THE INVENTION
[0016] The present invention will now be described more fully hereinafter with reference
to the accompanying drawings, in which exemplary embodiments of the invention are
shown. The invention may, however, be embodied in many different forms and should
not be construed as limited to the embodiments set forth herein; rather, these embodiments
are provided for thoroughness and completeness. Like reference character refer to
like elements throughout the description.
[0017] With reference to the figures a hinge 1 for a sliding vehicle door 2 is shown. The
hinge 1 and vehicle door 2 are in the figures 1-3 a left back door. However, the same
principle as disclosed below is applicable for the right front door, and reversed
for a left front door or a back door on the right side. The hinge has a first end
3 for being connected to the body side and a second end 4 for being connected to the
door 2. The first end has a pivot point and the second end 4 has a pivot point 5.
[0018] The pivot point 5 of the second end 4 comprises a running element 6, a wheel, for
running along a hollow profile rail 7 and the second end 4 further comprises a second
running element 8 arranged at a distance from the running element 6 of the pivot point
5.
[0019] The pivot point of the first end 3, the pivot point 5 of the second end 4, and the
second running element 8 form a triangle. In figure 1 a sliding door 2 is shown in
a closed position. The first end 3 of the hinge is pivotally connected to a fastening
bracket 11. As can be seen the hinge 1 is more or less in line with the hollow profile
rail 7 with the second end 4 partly outside the rail 7 with the second running element
8. The second running element is in the embodiment shown made up of two wheels, one
wheel on opposite sides of the hinge 1. Inside the hollow profile rail 7 is the running
element 6 (see figure 4) at the pivot point 5 of the second end 4.
[0020] When the door 2 is opened, the hinge 1 initially turns about the pivot point 5 at
the second end 4 of the hinge 1. Seen from above the hinge 1 rotates anti clockwise
about the pivot point 5 such that the second running element 8 of the hinge's 1 second
end 4 is received inside the hollow profile rail 7 through the part 10 of the rail
7 recess that has a width greater than the width of the second running element 8.
[0021] Both running elements 6, 8 are shown as pair of wheels equipped with ball bearings
12 in order to minimize the friction and thus the power needed to open the door.
[0022] When the second running element 8 is engaged with the rail 7, the hinge 1 moves linearly
relative the rail 7/door 2 upon further opening of the door as indicated in figure
2.
[0023] In order for the hinge 1 not to run out of the rail 7, a stopping bracket 13 is arranged
at one end of the rail 7. As can be seen in figure 3, the hinge 1 has reached the
stopping bracket 13 and this also means that the door is fully open. For increased
stability in the fully open position, the stopping bracket 13 is preferably equipped
with two pins that releasably fits in the openings 14 of the hinge, i.e. a kind of
plug and socket connection.
[0024] It is to be understood that the present invention is not limited to the embodiment
described above and illustrated in the drawings; rather, the skilled person will recognize
that many changes and modifications may be made within the scope of the appended claims.
For example, the rail could be T-shaped such that wheels or some sliding block could
grip and run on the outside of the flanges of the rail as running elements. Further,
the rail could be divided into two parts separated from each other instead of the
part with the opening 10 as shown in the embodiment of the drawings.
[0025] Also, the running elements could instead of wheels be sliding elements, for instance
some plastic block with low friction against the rail.
