Description
BACKGROUND OF THE INVENTION
[0001] The present invention relates to a vehicle hitch assembly,
and more particularly to a single reversible shank which allows the
attachment of accessory carriers to variously sized hitch
receivers.
[0002] It is often desirable to increase the capacity of a vehicle
to transport cargo by providing a carrier assembly for carrying
cargo on the outside of the vehicle. Various carrier racks exist
that support cargo at various locations on a vehicle. Some carriers
attach to receiver-type hitches available at the rear of many
vehicles. Such carriers are easy to attach and can support
substantial loads since they fit into a hitch designed specifically
for quick attachment of trailers and the like.
[0003] Although many vehicles include a receiver-type hitch, at
least two standard sizes of receiver-type hitches are commonly
available on various vehicles. Further, as many types of carrier
assemblies are available, particular combinations are often
incompatible.
[0004] In addition, when a carrier is attached to a receiver hitch
at the rear of a vehicle, it can inhibit access to the rear of a
vehicle and can interfere with the opening of the trunk, tailgate
or doors at the rear of the vehicle necessitating its removal from
the vehicle whenever the trunk, tailgate or rear doors must be
opened. This presents a significant disadvantage.
[0005] Accordingly, it is desirable to provide a carrier assembly
which will fit a multiple of a receiver-type hitches without
inhibiting access to the rear of a vehicle.
SUMMARY OF THE INVENTION
[0006] The accessory carrier assembly according to the present
invention generally includes a reversible shank having a first
segment and a second segment. A first portion is sized to engage a
first hitch receiver and a second portion is sized to engage a
second hitch receiver. A 2-inch female hitch receiver and the
1.25-inch female hitch receiver are typical of most hitch receivers
and the portions are preferably sized to engage these common
receivers, however, other sized segments may be provided to provide
engagement with a multiple of other sized female hitch
receivers.
[0007] An accessory carrier includes a support and a mount
assembly. The support is preferably a substantially L-shaped
tubular support which defines a second axis substantially
perpendicular to the first axis defined by the hitch receiver. The
support provides for the attachment of a variety of accessory
carriers. The carriers can include but are not limited to: bicycle
racks; ski racks; snowboard racks; accessory shelves; accessory
bustles; and the like. It should also be understood that other
accessories attachable to a hitch receiver will benefit from the
present invention.
[0008] When the accessory carrier is to be mounted to a vehicle
having a 2-inch female hitch receiver, the first portion of the
reversible shank is telescoped into the 2-inch female hitch
receiver and retained therein by a hitch pin. To attach the
accessory carrier to the reversible shank, the second segment is
located in the mount assembly and a fastener is passed through one
of a pair of apertures in the mount assembly and through one of a
pair of apertures through the second portion.
[0009] As the second portion is smaller than the distance between
the plates of the mount assembly, bushings are located between the
plates and the second portion. A pin is then located through the
other aperture in the first portion and the other aperture in the
plates. The accessory carrier can also be pivoted on a pivot axis
defined along the fastener by removing the pin.
[0010] When the accessory carrier is to be mounted to a vehicle
having a 1.25-inch female hitch receiver, the second portion of the
reversible shank is telescoped into the 1.25-inch female hitch
receiver and retained therein by a hitch pin. To attach the
accessory carrier to the reversible shank, the first segment is
located between the plates such that the pair of apertures located
through the plates are aligned with a pair of apertures located
through the second segment. Because the second segment is large
enough to fit between the plates at both apertures, the bushings
are not required.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
[0016] FIG. 1 illustrates an accessory carrier assembly 10 for
attachment to a vehicle (shown rather schematically at 12). The
carrier assembly 10 generally includes a reversible shank 14, and
bushings 16. The reversible shank 14 includes a first segment 18
and a second segment 20. Each segment 18,20 provides exterior
dimensions for mating engagement to a first and second female hitch
receiver 22 or 22' mounted to the vehicle 12 and to an accessory
carrier 28. The hitch receivers 22,22' are mounted to the vehicle
in a known manner and each defines a first axis 23.
[0017] The reversible shank 14 is preferably manufactured of a
substantially square first portion 24 which receives a
substantially square second portion 26. First portion 24 receives
the second portion 26 which is fixed therein by welding or the
like. Preferably, the first portion 24 is sized to engage a 2-inch
female hitch receiver 22 and the second portion 26 is sized to
engage a 1.25-inch female hitch receiver 22'. The 2-inch female
hitch receiver 22 and the 1.25-inch female hitch receiver 22' are
typical of most female hitch receivers and portions 24,26 are
preferred sized to engage these common receivers, however, other
sized portions may be provided for engagement with a multiple of
other sized female hitch receivers.
[0018] The accessory carrier 28 includes a support 30 and a mount
assembly 32. The support 30 is preferably a substantially L-shaped
tubular support which defines a second axis 31 substantially
perpendicular to the first axis 23. The support 30 provides for the
attachment of a multiple of known carriers (not shown). The
carriers can include but are not limited to: bicycle racks; ski
racks; snowboard racks; accessory shelves; accessory bustles; and
the like. It should also be understood that other accessories
attachable to a hitch receiver 22 will benefit from the present
invention.
[0019] The mount assembly 32 preferably includes a pair of parallel
plates 34 fixedly attached to the support 30 by welding or the
like. Other accessories attachable to a hitch receiver 22 can
directly include the mount assembly 32 such that the other
accessories will benefit from the present invention. A distance
sized to receive the larger first portion 24 of the reversible
shank 14 separates the plates 34. A pair of apertures 33 are
located through each of the plates 34. A stop aperture 35 is also
preferably located through the plates.
[0020] The second segment 20 of the reversible shank 14 includes a
pair of apertures 36. One of the apertures 36 is located through
the first portion 24 and the other aperture 36 is located through
the second portion 26. Preferably, the apertures 38 are pierced
through the substantially square first portion 24 while the pair of
apertures 36 are drilled through the solid substantially square
second portion 26. The portions 24,26 are aligned (FIG. 1A) such
that one of the apertures 36, 38 are concentric and the portions
24,26 are fixed together by welding or the like.
[0021] By collating one of the apertures 36 with one of the
apertures 38, the shank 14 is assured to be retained within the
hitch receiver irrespective of which hitch receiver is used.
Moreover, by passing a pin through the collocated apertures 36, 38
such that the pin passes through both portions 24,26, retention of
the portions 24,26 (FIG. 1A) is assured without regard to the joint
therebetween. The pair of apertures 36 and the pair of apertures 38
are spaced to correspond with the pair of apertures 33 located
through the plates 34 such that the first segment 18 of the
reversible shank 14 is attachable thereto.
[0022] The first segment 18 of the reversible shank 14 includes a
pair of apertures 38. The pair of apertures 38 are spaced to
correspond with the pair of apertures 36 and the pair of apertures
33 located through the plates 34 such that the first segment 18 of
the reversible shank 14 is also attachable thereto. Preferably, a
hitch pin aperture 40 is located between the pair of apertures 38
to receive a hitch pin 42 in a known manner.
[0023] The first portion 24 is telescopically receivable within the
2-inch female hitch receiver 22 and retained therein by the hitch
pin 42. Hitch pin 42 is preferably passable through a hitch
aperture 44 and through the corresponding hitch pin aperture 40.
Hitch pin 42 is retained by a fastener 46 such as clip 46. The
hitch pin aperture 40 is provided as the hitch pin 42 for the
2-inch female hitch receiver 22 is typically of a larger diameter
than a hitch pin 48 for the 1.25-inch female hitch receiver 22'.
Accordingly, the pairs of apertures 32, 36, and 38 are preferably
of an equivalent size which may be smaller than hitch pin apertures
40 and 44.
[0024] When the accessory carrier 28 is to be mounted to a vehicle
12 having a 2-inch female hitch receiver 22, the first portion 24
of the reversible shank 14 is telescoped into the 2-inch female
hitch receiver 22 and retained therein by the pin 42. To attach the
accessory carrier 28 to the reversible shank 14, the second segment
20 is located between the plates 34 such that the pair of apertures
33 located through the plates 34 are aligned with the pair of
apertures 36 located through the second segment 20. A fastener 50
is preferably passed through one of the apertures 33 and through
one of the apertures 36 located through the second portion 26.
[0025] Preferably, because the second portion 26 is smaller than
the distance between plates 32, the bushings 16 are preferably
located between the plates 34 and the second portion 26. Each of
the bushings 16 includes an aperture 17 such that the bushings 16
can receive and be retained by the fastener 50 which is passed
therethrough. A threaded fastener 52 such as nut 52 is then
threaded to the fastener 50 to retain the accessory carrier 28 to
the reversible shank 14. Washers 56 are preferably located between
the fastener 50, nut 52 and the plates 34 such that the accessory
carrier 28 can be easily pivoted on a pivot axis 55 defined along
fastener 50.
[0026] A pin 54 is then located through the other aperture 36 in
the first portion 24 and the other aperture 33 in the plates 34. A
clip 58 or the like retains pin 54 to the mount assembly 32. It
should be understood that the pin 54 can be another hitch pin 48
for the 1.25-inch female hitch receiver 22' or can be a separate
pin such as pin 54.
[0027] Referring to FIG. 2, the accessory carrier 28 is now mounted
to the vehicle 12 such that the second axis 31 is substantially
perpendicular to the first axis 23 (shown in phantom). Importantly,
should a user require access to the vehicle 12 through a rear door,
lift-gate, or the like (shown schematically at D), only pin 54 need
be removed. Preferably pin 54 is removed form aperture 33 and
located in stop aperture 35. The accessory carrier 28 can then be
pivoted on the pivot axis 55 (FIG. 1) defined along fastener 50.
Stop aperture 35 forms a stop that contacts the shank 14 to prevent
over rotation of the accessory carrier 28 and possible contact with
the ground G. Accordingly, the reversible shank 14 provides a
clearance C for accessories carried on the accessory carrier 28.
Further, by completely removing the pin 54 from the stop aperture
35, the accessory carrier 28 can be further rotated.
[0028] Referring to FIG. 3, when the accessory carrier 28 is to be
mounted to a vehicle 12 having a 1.25-inch female hitch receiver
22', the second portion 26 of the reversible shank 14 is telescoped
into the 1.25-inch female hitch receiver 22' and retained therein
by the pin 48. To attach the accessory carrier 28 to the reversible
shank 14, first segment 18 is located between the plates 34 such
that the pair of apertures 33 located through the plates 34 are
aligned with the pair of apertures 38 located through the second
segment 20. Because the second segment 20 is large enough to fit
between the plates 34 at both apertures 38, bushings 16 are not
required. Otherwise, assembly is the same as described above. The
accessory carrier 28 can again be pivoted and clearance is again
provided for accessories carried on the accessory carrier 28.
[0029] The foregoing description is exemplary rather than defined
by the limitations within. Many modifications and variations of the
present invention are possible in light of the above teachings. The
preferred embodiments of this invention have been disclosed,
however, one of ordinary skill in the art would recognize that
certain modifications would come within the scope of this
invention. It is, therefore, to be understood that within the scope
of the appended claims, the invention may be practiced otherwise
than as specifically described. For that reason the following
claims should be studied to determine the true scope and content of
this invention.
