ARTICLE CARRIER FOR A TRUCK BED
Abstract
A vehicle article carrier adapted for use with outer body
surfaces of a vehicle that are curved or non-parallel to one
another. The article carrier includes a pair of non-linear slats
that are secured in spaced apart relation to one another on the
outer body surfaces. A cross bar supporting assembly has a pair of
connecting members that support a cross bar at its outermost ends.
The connecting members are secured to slider members, and the
slider members are adapted to be secured to the slats. The
connecting members are secured to the outermost ends of the cross
bar and each have bores that enable the outermost ends to be
gradually received therewithin as the cross bar is moved along
portions of the slats where the distance between the slats
decreases, thus effectively shortening the cross bar. Conversely,
this coupling enables the length of the cross bar to be effectively
lengthened to accommodate increases in the distance between the
slats. Each connecting member further includes a slider having a
curved face portion which couples to an associated one of the slats
and which further helps to prevent jamming of the cross bar as it
is moved along the curved or non-parallel slats.

Description
FIELD OF THE INVENTION
[0001] The present invention relates to vehicle article carriers.
More particularly, the present invention relates to a vehicle
article carrier having a cross bar that is capable of being
supported from a pair of slats for adjustable movement along the
slats, and where the slats are non-linear or are mounted in an
slightly non-parallel arrangement on the outer body surface of a
vehicle.
BACKGROUND OF THE INVENTION
[0002] Vehicle article carriers are used in a wide variety of
applications for supporting and securing articles of various sizes
above an outer surface of a vehicle. Typically, vehicle article
carriers include a pair of slats or side rails (i.e. support rails)
that are secured to the outer body surface of the vehicle. Usually,
the side rails are straight and extend parallel to each other. The
side rails are typically secured along a major longitudinal length
of the vehicle roof, rear deck lid, or other surface of a
vehicle.
[0003] Usually, at least one cross bar is supported from the two
slats or side rails. The cross bar is secured to each support rail
by brackets that are rigidly fastened to each end of the cross bar.
Each bracket is slidably secured to one of the support rails to
allow for adjustable movement of the cross bar along the support
rails.
[0004] Typically, a tap plate extends from each bracket and is
disposed within an associated one of the support rails. The tap
plate may be threadably engaged with a user actuable, rotatable
locking knob or like element that allows the user to effectively
lock each end of the cross bar at a desired position along its
associated support rail. Thus, the cross bar can be securely
positioned as needed to accommodate a variety of articles having
many different shapes and dimensions.
[0005] Current vehicle article racks perform adequately for their
intended purpose when both side rails are straight and parallel.
However, due to the fixed length of the cross bar, many current
vehicle article carrier systems are not suitable for use with
support rails that are not spaced parallel to each other. For
example, when a cross bar of fixed length is moved along support
rails that are not parallel, the support brackets of the cross bar
may jam between the support rails as the distance between the
support rails decreases. Further, as the cross bar is moved in the
direction of increasing distance between the support rails, the
support brackets may also jam.
[0006] Also, current vehicle article carriers are not suitable for
use with curved (i.e., bowed) side rails. Specifically, as the
cross bar is moved along the curved rails, the cross bar and its
associated brackets may become jammed within the side rails at the
midpoints of the side rails where the spacing between the side
rails is greatest.
[0007] One system dealing with this problem is disclosed in U.S.
Pat. No. 6,279,802, issued Aug. 28, 2001, and assigned to the
assignee of the present application, the disclosure of which is
hereby incorporated by reference. This system has proven effective
for compensating for a degree of non-linearity in the support
rails, or non-parallel spacing of the support rails of a vehicle
article carrier system. Nevertheless, it would be desirable to
provide a vehicle article carrier system that is more specifically
intended to accommodate movement of a cross bar along bowed support
rails, or along support rails that are non-parallel to one another
to a very significant degree.
SUMMARY OF THE INVENTION
[0008] The present invention is directed to a vehicle article
carrier having a cross bar support member that is capable of being
moved along a pair of supporting rails that are curved (i.e.,
"bowed") and/or not parallel to one another. The article carrier is
generally comprised of at least two side rails that are adapted to
be fixedly secured to an outer body surface of a vehicle, a cross
bar, and at least two cross bar support assemblies. The cross bar
support assemblies are comprised of a slider and a connecting
member. The connecting member secures the cross bar to the slider
and the slider is secured to an associated one of the support
rails.
[0009] The cross bar is able to effectively extend and contract in
overall length. This is achieved through the use of the connecting
member at each end thereof. The connecting members allow end
portions of the cross bar to slide into and out of each of the
connecting members. For example, as the cross bar is moved to a
point where the support rails are spaced closer together, the ends
of the cross bar recede within the connecting members. However, as
the cross bar is moved along the support rails, as the distance
between the support rails is increasing, then the connecting
members are able to move apart from one another to effectively
lengthen the cross bar.
[0010] To even better allow the slider to slide along side rails
that are curved, each connecting member is pivotably coupled to its
associated slider. Each slider further includes a curved side rail
contact portion. Thus, as each slider moves along side rails that
are bowed outwardly relative to one another, the connecting members
pivot and the cross bar effectively lengthens from the connecting
members to follow the curve. As the slider moves along side rails
that are bowed inwardly to one another, the connecting members
pivot and the cross bar outer ends recede within the connecting
members to effectively shorten the cross bar and allow the sliders
to follow the curvature of the support rails. The curved support
rail contact portion allows the slider to easily follow curved
support rails without becoming jammed within the support rails.
[0011] Further areas of applicability of the present invention will
become apparent from the detailed description provided hereinafter.
It should be understood that the detailed description and specific
examples, while indicating at least one preferred embodiment of the
invention, are intended for purposes of illustration only and are
not intended to limit the scope of the invention.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0018] The following description of the preferred embodiment is
merely exemplary in nature and is in no way intended to limit the
invention, its application, or uses.
[0019] Referring to FIG. 1, there is shown a vehicle article
carrier apparatus 10 in accordance with a preferred embodiment of
the present invention. The article carrier apparatus 10 is shown
installed on an exemplary motor vehicle, illustrated as a pick-up
truck 12. Specifically, the apparatus 10 is shown installed along
the bed walls 14 of a truck bed 16. While FIG. 1 shows the
apparatus 10 secured to bed walls 14, it will be appreciated that
the apparatus 10 can just as readily be secured to a roof area or
other area of the vehicle 12 with little or no modification to the
apparatus 10. Also, the illustration of the apparatus 10 being
installed for use on a pick-up truck is only for illustrative
purposes. The apparatus 10 is suitable for use on virtually any
form of vehicle (e.g. sport utility vehicle, station wagon, sedan,
etc.) where there is a need for curved or bowed support rails to be
employed. The apparatus 10 could also be employed (albeit on a
smaller scale) with a little or no modification inside a cargo area
of a vehicle if desired.
[0020] The apparatus 10 generally includes a pair of support rails
in the form of elongated slats 18 (only one being visible in FIG.
1), at least two cross bar support assemblies 20, and at least one
cross bar 22. It will be appreciated that in many applications two
adjustably positionable cross bars will be used, but that one of
the cross bars 22 could just as readily comprise a fixed (i.e.,
non-movable) cross member. For the purpose of discussion and
illustration both of the cross bars 22 are adjustable cross
bars.
[0021] Slats 18 are secured to each bed wall 14 such that the slats
18 extend preferably at least a substantial portion of the length
of the bed walls 14. Each cross bar 22 extends between the slats 18
and is secured to the slats 18 by its associated cross bar support
assemblies 20.
[0022] It will be appreciated that while the slats 18 have been
illustrated as slats attached to interior wall surfaces of the bed
walls 14 in FIG. 1, the slats 18 may just as easily be formed as
slide rails and supported elevationally above the bed walls 14 by
suitable support feet at opposite ends thereof. Thus, the teachings
of the present invention are not limited only to the use of slats,
but also include the use of side rails that are elevationally
positioned over a surface.
[0023] FIGS. 2 and 3, provide a more detailed view of one of the
slats 18 and its associated support assemblies 20. While FIGS. 2
and 3, and the accompanying description, focus on a single support
assembly 20 and a single slat 18, it will be appreciated that the
following description applies equally to both of the slats 18 and
support assemblies 20 of the apparatus 10.
[0024] Each slat 18 includes a bottom wall 24 having one or more
spaced apart openings 26, a first end 28, a second end 30, an upper
wall 32, a lower wall 34, and inwardly turned flanges 36 and 38.
Flanges 36 and 38 extend approximately ninety degrees from the
upper wall 32 and the lower wall 34, respectively, to create upper
well 40 and lower well 42. The wells 40 and 42 help to form a
channel 43 along the length of the slat 18. Slat 18 is secured to
the bed wall 14 by way of openings 26 using a plurality of
conventional fastening elements such as threaded fasteners (not
shown), rivnuts, etc. The first end 28 and second end 30 each
include an end cap 44. End caps 44 may be secured to the first end
28 and the second end 30 in any suitable manner but are preferably
secured using suitable threaded fasteners 45 that engage openings
26 via apertures 46 of the end caps 44.
[0025] Support assembly 20 comprises a slider 48 and a cross bar
connecting member 50. The slider 48 generally includes an upper
portion 52, a lower portion 54, a side rail contact portion 56, and
a bore 58 forming a connecting member receipt portion. The upper
portion 52 and the lower portion 54 each have vertically aligned
apertures 60 for the receipt of a suitable fastening device, such
as retaining pin 62. Connecting member 50 is sized to fit within
bore 58 and to be secured within the bore portion 58 by retaining
pin 62. Slider 48 may be made from any suitable material but is
preferably manufactured from a polymer of suitable strength and
rigidity.
[0026] Slider 48 is secured to slat 18 by way of tap plate 64. Tap
plate 64 may be made of any suitable material but is preferably
made of a metal, and more preferably from steel. The tap plate 64
generally includes a threaded center aperture 66 and two opposing
side notches 68. Tap plate 64 is inserted within the channel 43 and
can slide along the length of slat 18 within the wells 40, 42. The
tap plate 64 is shaped so as to be convex in its relaxed (i.e.
unlocked) position, relative to side wall 24 once installed (i.e.,
so as to bow away from side wall 24).
[0027] Slider 48 further includes a notched portion 69 having a
threaded aperture 70 located within side rail contact portion 56.
Aperture 70 threadably receives a threaded post 72 of a user
graspable locking knob 74 which is partially housed in the notched
portion 69. The post 72 extends through, aperture 70 to threadably
engage center aperture 66 of the tap plate 64. Thus, by securing
tap plate 64 to the slider 48, the control knob 74 secures the
slider 48 to slat 18.
[0028] Actuation of locking knob 74 in a first direction causes tap
plate 64 to be drawn towards the side rail contact portion 56 and
into contact with flanges 36, 38. This clamps the side rail contact
portion 56 against the slat 18 at a given position. In contrast,
rotation of control knob 74 in the opposite direction causes tap
plate 64 to disengage flanges 36, 38 to permit the movement of
slider 48, and thus cross bar 22, along slat 18.
[0029] Slider 48 further comprises a pair of extensions 76. Each
extension 76 forms a boss portion that extends outwardly from the
side rail contact portion 56 to engage a respective side notch 68
of tap plate 64. Extensions 76 prevent the tap plate 64 from
rotating during the rotation of locking knob 74.
[0030] It will be appreciated that the surface of side rail contact
portion 56 is not linear (i.e., not perfectly flat). Rather, the
surface of side rail contact portion 56 is rounded or arcuate. This
helps to prevent the slider 48 from jamming against slat 18 if slat
18 is curved (i.e., bowed) inwards towards slider 48. Side rail
contact portion 56 is formed with a radius of curvature as needed
to ensure that the slider 48 will not jam. In one preferred form
the radius of curvature is preferably between 300 cm-400 cm. Slider
48 can also slide along slats 18 that are curved (i.e., bowed)
outwardly and away from slider 48 without jamming.
[0031] Cross bar 22 is secured to its associated support assemblies
20 by connecting members 50. Each connecting member 50 is an
elongated, tubular-like member that can be made of any suitable
material, such as a polymer of a suitable strength and rigidity, or
from aluminum. The connecting member 50 has a hollow 50a to enable
receipt of one end of cross bar 22 therein. The connecting member
50 is generally comprised of a first end 78, a second end 80, a top
portion 82, and a bottom portion 84.
[0032] First end 78 is received by connecting member receipt
portion 58 of the slider 48. First end 78 includes a through hole
86 that is aligned with apertures 60 when the first end 78 is
inserted into connecting member receipt portion 58. Once aligned,
pin 62 is inserted through apertures 60 and through hole 86 to
pivotally secure connecting member 50 to the slider 48. The use of
pin 62 allows the connecting member 50, and associated cross bar
22, to pivot relative to slider 48. Further, when the cross bar 22
is not in use, the cross bar 22 and connecting member 50 may be
separated from slider 48 by removing the pin 62 from slider 48.
[0033] First end 78 further includes a tie-down aperture 88.
Tie-down aperture 88 may be used to further help secure articles to
the apparatus 10. The tie-down aperture 88 may be used with any
suitable tie-down device, such as a bungee cord, nylon strap, etc.,
that help secure articles to the cross bar 22.
[0034] Generally located between first end 78 and second end 80 is
an aperture 90 for receipt of a locking member 92. Locking member
92 includes a threaded post 94 that extends through aperture 90 and
is held in place by fastener 96. Threaded post 94 engages a
threaded aperture 100 of a cross bar tap plate 98. Cross bar tap
plate 98 is seated within tap plate retainer 102. Retainer 102
includes curved portions 104 that function as springs to bias tap
plate 98 against an inside surface of the cross bar 22, as will be
described momentarily.
[0035] Referring to FIGS. 1 and 3, cross bar 22 is generally
comprised of an elongated tubular, oval shaped (in cross-section)
member having a top portion 106, a bottom portion 108, a first
outer most end 110, and a second outer most end 112 (FIG. 1). In
FIG. 3, the top portion 106 has a channel 114 that extends the
length of the top portion 106. The channel 114 is bordered by
recessed flanges 116. A majority of the channel 114 is covered by a
rubber bumper 118. The rubber bumper 118 is seated within the
recessed flanges 116. Rubber bumper 118 does not completely extend
to the first end 110 and to the second end 112, thus leaving
portions of the channel 114 exposed at ends 110 and 112.
[0036] The areas of channel 114 exposed at first end 110 and at
second end 112 are inserted within their respective connecting
members 50 so that the exposed portions at each end of the channel
114 are located within the connecting members 50. Tap plate 98 and
retainer 102 are disposed within the channel 114 and curved
portions 104 of the tap plate serve to hold the tap plate 98
against the recessed flanges 116. Threaded post 94 extends through
channel 114 into engagement with threaded aperture 100.
[0037] When the locking member 92 is rotated in a first direction
the tap plate 98 is used to clamp the end 106 of the cross bar 22
to the connecting member 50. The same action occurs at the opposite
end 112 of the cross bar 22. This secures the cross bar 22 in
position and prevents it from sliding inwardly or outwardly
relative to the connecting member 50. When the locking member 92 is
rotated in a second direction, the tap plate 98 is loosened, thus
allowing the ends 110, 112 of the cross bar 22 to be drawn out
from, or to recede within, their respective connecting members 50
as the cross bar 22 is moved along the non-linear slats 18.
[0038] Referring to FIG. 4, the apparatus 10 can be seen where one
cross bar 22 is disposed at the point where the spacing between the
slats 18 is greatest. In FIG. 5, it can be seen how the apparatus
10 allows for the decreasing distance between the slats 18 by
enabling the outermost ends 110, 112 of the cross bar to be
gradually and increasingly received within their respective
connecting members 50.
[0039] To further enhance sliding movement of the slider 48 along
slats 18 that are curved, sliders 48 can each pivot relative to
their respective connecting members 50 as side rail contact
portions 56 of the slider 48 move along the slats 18. Thus, as the
sliders 48 move along slats 18 that are concave to each slider 48,
the sliders 48 pivot to follow the curvature of its associated slat
18. As the sliders 48 move along slats 18 that are convex to the
sliders 48, the outermost ends 110, 112 of the cross bar 22 recede
within their respective connecting members 50 to follow the
curvature of the slats 18. The curved side rail contact portions 56
also help to allow the sliders 48 to follow curved slats or side
rails during positioning of the cross bar 22 without becoming
jammed between the slats or side rails.
[0040] The apparatus 10 thus enables a cross bar to be used with
non-parallel or bowed support rails. This significantly enhances
the utility of the apparatus 10 by allowing it to be used with a
wider variety of vehicle body styles where non-parallel or bowed
