The present invention relates to a front end of a transportation device which uses handle bars and a fork segment for securing a wheel, such as a two-wheeled vehicle, three-wheeled vehicle, or the like.
There are various types of front end assemblies for transportation devices which use handle bars. Many such devices disclose triple tree assemblies which are well known in practice. Some devices disclose multiple types of suspensions or stabilizers for front end assemblies.
One such device discloses a front end assembly that provides the illusion that the front fork tubes continue upward through the triple tree to form the handlebars. However, this is just an illusion does not teach a unitary piece comprising both handle bars and fork members.
A triple tree assembly, while popular, interrupts the smooth flow of the front end. With the popularity of custom motorcycles rising, many riders desire an aesthetically pleasing smooth flowing front end. Further, triple tree assemblies are expensive to manufacture and repair. Alterations in a triple tree can also be difficult, costly, and time consuming. The removal and replacement of a front end for a vehicle, such as a motorcycle, can be extremely complicated and time consuming.
Further, because previously-known devices comprise multiple components secured together via fasteners, there is a risk of unintentional disassembly during use, causing risk of injury or death of the rider and/or passenger.
Therefore, it is readily apparent that there is a need for a unitary vehicular front end which is more cost efficient in production and repair, provides an aesthetically pleasing design, and allows for the easy removal of the front end from the vehicle frame such as for replacement and/or service of the front end or frame.
Briefly described, in a preferred embodiment, the present invention overcomes the above-mentioned disadvantages and meets the recognized need for such a device by providing a unitary vehicular front end comprising a left handle bar section, a right handle bar section, a left fork segment, and a right fork segment. The left handle bar section and the left fork segment meet forming one continuous line comprising the left side. The right handle bar section and the right fork segment meet forming one continuous line comprising the right side. A connecting member which bridges the left and right sides together is disposed proximate the meeting of the handle bar sections and the fork segments, thus forming a single, unitary piece for a front end of a vehicle, such as a two-wheeled or three-wheeled vehicle. The single unitary piece as formed does not require assembly of its structural handlebar, for and connecting members.
Such a unitary front end for a vehicle reduces the cost and is more aesthetically pleasing than other devices currently extant in the art. Further, no adjustments or alterations are needed once it is installed. This reduces manufacturing, repair, and replacement costs, as well as, the amount of time spent working on the transportation vehicle.
Further, the unitary vehicular front end also includes a central bar extending substantially perpendicular from the connecting member. This central bar may be used to receive the frame of a motorcycle or another type of two-wheeled or three-wheeled vehicle. The frame may be secured to the unitary vehicular front end by any known methods, but particularly a nut may be screwed on to a threaded portion of the central bar to secure the frame around the central bar. This configuration allows for the unitary vehicular front end to be attached to the frame of a vehicle by the central bar, wherein the central bar comprises a threaded portion, and wherein a nut is secured to the threaded portion of the central bar. Thus, should the unitary front end need to be removed from the frame, time is saved by removal of the single nut. Further, another unitary vehicular frame, or alternately a unitary front end, could be secured in rapid fashion to a different front end or frame, respectively, saving time and money and allowing for a greater flexibility in modifying the vehicle depending on terrain or circumstances.
The unitary vehicular front end may also have apertures on the handle bar sections to provide an attachment point for one or more mirrors. An attachment bar may also bridge the left and right sides, wherein the attachment bar has an aperture to receive at least one head light assembly. The attachment bar may preferably also provide apertures for connecting turning lights. Providing mirrors and lights increases the safety of the vehicle. Shock absorption may be provided by a shock and rocker system as known in the art, thus providing a higher level of comfort to the user.
The unitary front end for a vehicle, such as, for exemplary purposes only, a motorcycle or the like, allows for more cost efficient construction and repair, easier assembly, and a more aesthetically pleasing design. Further, the unitary vehicular front end can be easily removed more quickly for replacement, repairs, or changes in circumstances, thus saving time and money.
According to its major aspects and broadly stated, the present invention in its preferred form is a unitary front end for a vehicle, comprising left and right sides formed by a handle bar section and a fork segment, wherein the left and right sides are connected via a connecting member disposed at approximately the midpoint of the sides. It will be recognized by those skilled in the art that the connecting member could be disposed higher or lower than the approximate midpoint of the unitary front end.
In a preferred embodiment, the unitary vehicular front end comprises left handle bar section having a left fork segment extending from said left handle bar section, a right handle bar section having a right fork segment extending from said right handle bar section, a connecting member disposed between and connecting said left handle bar section and said right handle bar section, wherein said left handle bar section, said right handle bar section, said left fork section, said right fork section, and said connecting member comprise a single steering mechanism.
In a further embodiment, the unitary vehicular front end may further comprise a central bar for receiving a transportation device frame, wherein the transportation device frame is in pivotal communication with said connecting member.
More specifically, the present invention in a preferred embodiment comprises a unitary front end for a vehicle, such as a two or three-wheeled vehicle.
