Description
CROSS-REFERENCE TO RELATED APPLICATIONS
[0001] This is a divisional application of Ser. No. 11/975,734
filed Oct. 19, 2007 which application claims priority to and
incorporates by reference in their entirety for all purposes the
following U.S. Provisional Patent Applications: Ser. No. 60/853,116
filed Oct. 20, 2006 and Ser. No. 60/958,475 filed Jul. 6, 2007.
BACKGROUND
[0002] Top-mounted vehicle racks provide a versatile platform for
transporting bicycles, skis, snowboards, boats, cargo boxes, gear
racks, and other items. Such racks typically include a pair of
crossbars that extend side-to-side across the top of a vehicle.
Each crossbar is supported on each side of the vehicle's roof by a
tower, where the length of each crossbar and the distance between
crossbars depend on factors such as the shape and size of the
vehicle's roof. The towers supporting the rack crossbars are
securely fastened to the vehicle to prevent the rack from slipping
during use.
[0003] A typical top-mounted boat mount system includes two
crossbars of the type described above, with supporting mounts of
some type (e.g., a pair of saddles or J-shaped cradles) attached to
the crossbars for supporting a boat, for example, a kayak or a
canoe. After placing a boat on the mounts, the user then secures
the boat to the rack by strapping it to both the cradles and the
crossbars. However, placing the boat on the mounts may be
cumbersome and difficult, and may result in damage to the vehicle,
the boat, or injury to person(s) loading the boat.
[0004] A common method of placing a boat on a vehicle roof rack is
for a user to lift the bow of the boat onto the rear mount from the
rear of the car, and then to slide the boat forward. This method
has the advantage of allowing the user to lift only one half of the
boat at a time, but it has the disadvantage that the bow of the
boat often touches the upper rear corner of the car, resulting in
scratches or other damage either to the car or the boat. An
additional problem with this method is that the boat may be
difficult to slide on the rear mount, due to friction between the
mount and the boat hull.

DETAILED DESCRIPTION
[0017] As shown in FIGS. 1 and 2, boat loading device 10 attaches
to front and rear crossbars 12, 14 of a rack disposed on top of a
vehicle. Loading device 10 has a roller 40 located behind rear
crossbar 14. Roller 40 does not interfere with other supporting
boat mounts or rack components installed on the crossbars, such as
saddles 15 or J-cradles (not shown). As a result, the user may
choose any desired supporting mounts to use in conjunction with
loading device 10, or may add loading device 10 to a rack
previously configured with supporting boat mounts of any type.
[0018] Loading device 10 includes a pair of longitudinal load bars
18, 20, which distribute the any load placed on the loading device
to the roof of the vehicle via crossbars 12, 14. Load bars 18, 20
may be attached to crossbars 12, 14 by any suitable mechanism, such
as with front clamps 70 and/or rear clamps 50, which may be
configured to accommodate crossbars of various cross-sectional
shapes. Load bars 18, 20 may be attached to roller 40 via t-lugs
42. As shown in FIG. 1, load bars 18, 20 are adjustable from side
to side, allowing the user to configure the bars to accommodate
locations of the crossbar towers, as well as any other preexisting
roof rack components. As shown in FIG. 1, loading device 10 may
have a width approximately equal to or slightly greater than the
width of the vehicle. This allows the device to be used for loading
of two or more boats onto a single vehicle without additional
adjustments of the roller. As apparent in FIGS. 1 and 2, a boat or
other object may be loaded into saddles using device 10 without the
boat touching the vehicle.
[0019] Partial views of roller assembly 40 are depicted in FIGS. 3
and 4. Roller assembly 40 includes crossbar 41 attached to distal
ends of load bars 18, 20 via t-lugs 42. Roller extrusion 43
including roller pad 44 holds a roller bar (not shown). The roller
bar may be made of any suitable material, including elastomers. The
roller extrusion 43 may be coupled to crossbar 41 via endcap 45.
Endcap 45 may extend partially into roller extrusion 43, and may be
stabilized within extrusion 43 by bushing 46. Bushing 46 may be
configured to rotate around endcap 45. Roller assembly 40 may be
approximately 40'' wide, which allows the loading of two boats side
by side. Additionally, crossbar 41 may be non-circular, for
example, oval-shaped to prevent it from rotating within t-lugs 42
(as shown in FIG. 13), while allowing sideways movement of roller
40. Alternative configurations for crossbar 41 may be used to
prevent rotation of crossbar 41 within t-lugs 42. For example, the
crossbar may have other cross-sectional shapes such as rectangular,
triangular, or may have ridges, flanges, or other projections that
prevent rotation.
[0020] T-lugs 42 are adjustable along crossbar 41. This allows for
placement of load bars 18 and 20 at various distances from one
another, making loading device 10 compatible with a variety of
vehicles and boat saddles. T-lugs 42 may be clamped to crossbar 41
via tamper-proof fasteners or bolts, to prevent theft.
[0021] Roller 40 may be adjustable between multiple positions, as
shown in FIGS. 1 and 2. In a stowed or stored position roller 40 is
located relatively close behind rear crossbar 14, to allow full use
of the vehicle's rear door (such as a hatch) without interference
from roller 40. In a loading/unloading position, as shown in FIGS.
1 and 2, roller 40 is located to the rear of the back corner of the
vehicle, to allow the boat to move on the roller without contacting
the vehicle.
[0022] As shown in FIG. 1, roller 40 may be moved back and forth by
sliding load bars 18, 20 back and forth through clamps 50, 70. As
described in more detail below, one or more of clamps 50, 70 may be
equipped with a stop break, or lock to restrict back and forth
movement of roller 40 and load bars 18, 20. Roller 40 may also be
adjustable in a side-to-side direction relative to the vehicle as
shown in FIG. 1, so the roller may be approximately centered
underneath each boat being loaded side by side.
[0023] Support bars 18, 20 may be affixed to the cross bars using
rear clamps 50 and front clamps 70. As shown in FIGS. 5 and 6, rear
clamp 50 includes upper and lower jaws 52, 54 manipulable towards
one another to secure loading device 10 to rear crossbar 14. T-bolt
56 is adapted to be coupled with nut 58 via intermediate threaded
member 60, and is manipulable to bias lower jaw 54 toward upper jaw
52. Lower jaw 54 is rotatably coupled to upper tube member 62 via
hinge 64. Upper tube member 62 receives bar 18 or 20.
[0024] Quick release clamp 66 may be disposed on upper tube member
62 of rear clamp 50 via a tightening device 68, as shown in FIG. 7.
Quick release clamp 66 may be actuated to restrict or permit
sliding movement of load bar 18 or 20 through tube member 62, thus
enabling back and forth movement of roller 40 between stowed and
loading positions. For example, clamp 66 may be tightened by moving
quick release lever 69 toward clamp 66. Clamp 66 likewise may be
released (i.e. untightened) by pulling quick release lever 69 away
from clamp 66. In some embodiments, the tightness of clamp 66 may
be micro-adjusted by releasing quick release lever 69 and spinning
it to tighten a screw in tightening device 68.
[0025] As shown in FIGS. 7 and 8, front clamp 70 includes upper and
lower jaws 72, 74 manipulable toward one another to secure load bar
18 or 20 to crossbar 12. T-bolt 76 is coupled with nut 78 via
intermediate threaded member 80 to bias lower jaw 74 against upper
jaw 72. Lower jaw 74 may be rotatably coupled to upper tube member
82 via hinge 84. Upper tube member 82 receives load bar 18 or
20.
[0026] Front clamp 70 may also include stop collar 86 coupled to
load bar 18 or 20 to limit how far load bar 18 or 20 may slide
towards the rear of the vehicle. Stop collar 86 may include a
security mechanism, such as a tamper-proof screw for tightening
stop collar 86 around load bar 18 or 20, making removal of roller
40 and/or other components of loading device 10 difficult,
discouraging theft.
[0027] T-bolt 76 on front clamp 70 may be configured so that when
upper member 82 receives load bar 18 or 20, t-bolt 76 cannot be
rotated. This arrangement prevents loosening of clamp 70 when load
bar 18 of 20 engages tube member 82.
[0028] The various jaws of rear clamps 50 and front clamps 70 may
be adapted to accommodate variously-shaped cross beams. Such shapes
may include circles, ellipses, squares, rectangles, factory default
vehicle rack shapes, or any other shape found in cross beams sold
by various manufacturers. The jaws may also include jagged edges,
curves, high friction materials, etc., to improve their grip on
crossbars.
[0029] Various alternative examples of loading devices may include
only one longitudinal support bar, or may include two support bars
configured differently from the embodiment described above and
shown in FIGS. 1-8. For example, FIG. 9 shows alternative L-shaped
loading device 100 having a single longitudinal support bar 102,
and roller 104. Roller 104 may be adjustable from a storage
position to a loading/unloading position, through extension of
support bar 102 to various lengths. For instance, the support bar
may include a telescoping extension portion 108 configured to slide
in and out of outer sleeve portion 110. Quick release gripping
device 112 may be provided to control freedom of back and forth
movement of extension portion 108.
[0030] FIG. 10 shows another loading device 200 that includes a
single longitudinal support bar 202, and roller 204. Support bar
202 is configured to lie between pairs of saddles 206, 208 that are
attached to the crossbars of a rooftop rack. Support bar 202 is
attached to the crossbars at locations between the saddles of each
pair.
[0031] FIG. 11 shows still another loading device 300 having a
single longitudinal crossbar 302, and a roller 304. Crossbar 302 is
configured to lie to one side of supporting saddle mount pairs 306,
308. Hinge 310 allows roller 304 to be selectively pivoted between
a stored position and a loading/unloading position. This may allow,
for example, improved aerodynamics during transport of a boat, and
also may allow the roller to be pivoted to one side of the vehicle
to allow access to a rear hatch. Loading device 300 is preferably
provided with a back and forth movement device similar to those
described above.
[0032] FIG. 12 shows yet another example. Loading device 400 has
dual longitudinal support members 402, 404 connected at both ends
to form loops 406, 408. Support members 402 and 404 are configured
to be attached to the crossbars of a rack adjacent supporting boat
mounts such as saddles 410, 412. Loop 406 extends far enough
laterally so that roller 414 may slide along the loop 406 until
roller 414 is aligned with the saddles. Alternatively, a roller may
extend along the entire width of loop 406. Support members 402 and
404 may further be connected by one or more connecting members 416,
418 configured to support and securely transport accessories, such
as paddle 420.
[0033] FIG. 13 shows yet another example. Loading device 400 has
dual longitudinal support members 402, 404 connected at both ends
to form loops 406, 408. Support members 402 and 404 are configured
to be attached to the crossbars of a rack adjacent supporting boat
mounts such as saddles 410, 412. Loop 406 extends far enough
laterally so that roller 414 may slide along the loop 406 until
roller 414 is aligned with the saddles. Alternatively, a roller may
extend along the entire width of loop 406. Support members 402 and
404 may further be connected by one or more connecting members 416,
418 configured to support and securely transport accessories, such
as paddle 420.
[0034] There are various alternative ways to facilitate forward and
backward movement of roller 40 relative to the rear end of a
vehicle. One approach is to equip each of load bars 18 and 20 with
a telescoping device. Each load bar may have an outer tube secured
in a constant position by crossbar clamps. A smaller diameter tube
is then positioned concentrically in the outer tube and is moveable
to adjust the effective overall length of the load bar. The
position of the small tube relative to the outer tube may be locked
by a clamp device located either in one of the crossbar clamps or
in a separate clamp device.
[0035] Although the present disclosure has been provided with
reference to the foregoing operational principles and embodiments,
it will be apparent to those skilled in the art that various
changes in form and detail may be made without departing from the
spirit and scope of the disclosure. The present disclosure is
intended to embrace all such alternatives, modifications and
variances. Where the disclosure recites "a," "a first," or
"another" element, or the equivalent thereof, it should be
interpreted to include one or more such elements, neither requiring
nor excluding two or more such elements. Furthermore, any aspect
shown or described with reference to a particular embodiment should
be interpreted to be compatible with any other embodiment,
alternative, modification, or variance.
