## Background
FIELD OF THE INVENTION
The invention herein pertains to an apparatus for towing a motorcycle (bike) by lifting and securing the front of the bike behind a tow vehicle.
DESCRIPTION OF THE PRIOR ART AND OBJECTIVES OF THE INVENTION
U.S. Pat. No. 6,352,401 to LeMay discloses a carrier apparatus for attachment to the rear of a tow vehicle. The LeMay apparatus includes a member extensible for receiving the front wheel of a bike and retractable to lift the front wheel for towing. The extensible member includes opposing arms adapted to receive straps securing the front wheel to the apparatus.
The LeMay carrier, however, does not pivot when the tow vehicle changes directions. Rather, the rear of the bike pivots in relation to the front. With this system, often, the rear of the bike swings away from a turning direction of the tow vehicle under tow, which is undesirable.
Therefore, an objective of the present invention is to provide an apparatus for towing a bike behind a tow vehicle that pivots to turn the bike when the tow vehicle changes its direction.
Another objective of the present invention is to provide an apparatus for towing a bike behind a tow vehicle that maintains control of the bike.
Another objective of the present invention is to provide an apparatus for towing a bike behind a tow vehicle that has a selectively variable width.
Yet another objective of the present invention is to provide an apparatus for towing a bike behind a vehicle that is capable of use with a variety of motorcycle types.
Various other objectives and advantages of the present invention will become apparent to those skilled in the art as a more detailed description is set forth below.
SUMMARY OF THE INVENTION
The aforesaid and other objectives are realized by providing embodiments of an apparatus for towing a bike, tricycle or the like having front and rear wheels. In the preferred embodiment, the apparatus includes a pivoting tongue, a base and an extensible support member for receiving a front wheel, or at least a front end portion, of the bike while permitting one or more rear wheels to remain in contact with the ground. An opposing pair of tie arms for connection to the base of the apparatus are each carried by a pair of support arms, which are pivotably connected to the base to rotate toward the support member for storing the apparatus and away from the support member to secure the tie arms to the base. The tie arms include strap receiving brackets for fastening the bike to the apparatus and stabilizing the bike under tow.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT AND OPERATION OF THE INVENTION
For a better understanding of the invention and its operation, turning now to the drawings, FIG. 1 shows the preferred embodiment of apparatus 10 for connection to the rear of vehicle V for towing bike B, although apparatus 10 can also be employed to tow a tricycle or the like behind vehicle V. FIG. 1 shows apparatus 10 including support member 20 for receiving the front of bike B, pivoting tongue 14, base 30, and tie arm 42. Retaining straps 66, preferably in the form of nylon ratchet straps, are used to secure bike B to apparatus 10.
FIGS. 2-5 show apparatus 10 in a preferred storage configuration. Upper 46 and lower 48 support arms are connected to one side of base 30 at ends 46a, 48a, and upper 46′ and lower 48′ support arms are connected, at ends 46a′, 48a′, respectively, to an opposite side. Base 30 includes support arm receiving plate 52 defining opposing openings aligned with openings defined by ends 46a, 46a′, respectively, of upper support arms 46, 46′ for receiving fasteners pivotably retaining support arms 46, 46′ in connection with base 30. Another support arm receiving plate 54 defines opposing openings for alignment with openings defined by ends 48a, 48a′ respectively of lower support arms 48, 48′. Upper 46′ and lower 48′ support arms are pivotably connected at distal ends 46d′, 48d′, respectively, to tie arm 42′ between end 42a′ and distal end 42d′ of arm 42′. Similarly, upper 46 and lower 48 support arms are pivotably connected at ends 46d, 48d, respectively, to tie arm 42 between end 42a and distal end 42d of arm 42. In the storage configuration of apparatus 10, upper 46, 46′ and lower 48, 48′ support arms have been rotated toward support member 20 about receiving plates 52, 54, the fastener receiving openings of which are spaced generally lateral the remainder of base 30 to permit rotation to the storage configuration. Lock 112 preferably includes a pair of alignable opening and a pin for insertion through the openings for retaining tongue 14 in fixed relationship to base 30.
FIGS. 6-8 show apparatus 10 in the preferred configuration for use. Support arms 46, 48 and 46′, 48′ have been rotated from support member 20 to align openings at ends 42a, 42a′ of opposing tubular tie arms 42, 42′, respectively, with openings in tie arm receiving plate 56 of base 30. Distal ends 42d, 42d′ of tie arms 42, 42′ include strap receiving brackets 44, 44′, respectively, that, preferably, each include an eye bolt selectively secured in one of a plurality of openings 47 defined by distal ends 42d, 42d′ of tie arms 42, 42′, respectively. Fasteners, along with support arms 46, 48 and 46′, 48′ retain tie arms 42, 42′ in substantially stationary disposition with respect to base 30 to stabilize bike B under tow, although arms 42, 42′ may bend or flex slightly in response to forces resulting from securing bike B to apparatus 10 and towing bike B.
In an alternative embodiment of the apparatus (not shown), only one support arm is associated with each tie arm, and can optionally be disposed in coplanar alignment in front of or behind, rather than above or below, the tie arm.

FIG. 7 also shows a pair of opposing L-shaped side brackets 98 on cantilever 22 and a like pair of opposing L-shaped side brackets 98 on forward stop 24 for positioning bike B on support member 20. Brackets 98 include elongated openings for receiving fasteners fixing brackets 98 to forward stop 24 and cantilever 22. The elongated openings allow brackets 98 to be slidably adjusted depending on the width of the tire. Both forward stop and cantilever 22 include U-shaped handles to assist in securing and stabilizing bike B with straps 66 as needed.
With reference in particular to FIG. 8, tongue 14 is pivotably connected to base 30 by vertical or very nearly vertical rod 95 and lock 122 retains tongue 14 in a fixed position with respect to base 30 for loading and unloading the bike.
With reference to FIGS. 1-8, a preferred method of preparing apparatus 10 for towing bike B behind vehicle V includes, initially, with apparatus 10 in a stored condition, securing pivoting tongue 14 in the vehicle's trailer hitch and pivoting the opposing pairs of support arms 46, 48 and 46′, 48′ away from support member 20. Lock 112 can be disengaged and mechanism 80 operated to extend support member 20 downwardly with respect to base 30 to or very nearly to the ground to load the front of bike B on cantilever 22 against forward stop 24. Retaining straps 66 secure the front wheel to support member 20.
Once secured mechanism 80 is operable to retract support member 20, lifting the front of bike B while leaving the rear wheel of bike B on the ground. Once support member 20 is fully retracted, lock 112 can be engaged to retain member 20 in a fixed position with respect to base 30. Support arms 46, 48 and 46′, 48′ may be rotated to align respective ends 42a, 42a′ of tie arms 42, 42′ with openings defined by plate 56 for fastening with conventional nuts and bolts 57, 57′ as seen in FIG. 7. Retaining straps 66 are preferably fastened to the front and rear of bike B and strap receiving brackets 44, 44′ to secure and stabilize bike B behind the tow vehicle Vas demonstrated in FIG. 1.
