Anti-fouling faceshield
An Anti-fouling Faceshield is disclosed. The faceshield attaches to a conventional motorcycle helmet. The faceshield is particularly suited to competitive dirtbike racing where large amounts of mud are thrown onto riders' goggles in a short period of time. It is preferably spring-loaded so that the rider need simply pull a release lever to cause the faceshield to flip up and away from the face opening of the helmet. The main faceshield further has an upper shield extending upwardly from it to protect the pivot point/hinge area of the mechanism from being fouled with mud and other foreign bodies.
1. Field of the Invention
This invention relates generally to motorcycle safety accessories and, more specifically, to an Anti-fouling Faceshield.
2. Description of Related Art
Motorcycle and bicycle helmets are available in a wide variety of shapes and sizes to suit a rider's individual tastes as well as the environment in which the cycle is being ridden. One very challenging environment is off-road or dirt biking, and more particularly, dirt bike racing. This particular environment not only results in special helmet designs, but also special challenges to any existing designs.
The faceshield 12 on the conventional helmet 10 attaches on each side with a ratcheting pivot hinge 16. The ratcheting effect of the hinge 16 provides some (tension-adjustable) resistance to movement of the faceshield 12. Consequently, then the faceshield 12 is placed in the down position, it will stay down; when the faceshield 12 is placed in the up position, it will stay in that position. In order to move the faceshield 12, then, the rider must reach up and push the shield 12 up or down.
When the faceshield 12 is in the up position 12, the face opening 18 formed in the front of the helmet 10 is fully exposed to the front of the helmet 10. This means that the rider's face is fully exposed to the front of the helmet 10. It is this aspect of the conventional design that causes motocross riders problems. It is common that motocross track operators wet down the dirt surfaces prior to a race in order to keep the dust down, as well as to increase the difficulty of the course. As a result, it is natural for a rider's faceshield 12 to become opaque due to excessive amounts of mud being sprayed onto the shield 12 by other riders. This is particularly prevalent at the start line for a race—when the riders first start, they are all in tight, close proximity to one another, and all are spinning their tires to get a quick launch.
Historically, the rider would simply have to flip up their faceshield 12 by hand once it became excessively soiled. Because conventional faceshields 12 do not provide enough clearance between the rider's face and the shield 12 for the rider to wear a pair of goggles underneath the shield 12, the rider's face has historically been exposed to the flying mud once the shield 12 has been raised.
Furthermore, raising the faceshield 12 can be an unwanted distraction to the rider during a particularly challenging stage in a race. The less time that the rider needs to remove his or her hand from the handlebars in order to retract or open the faceshield 12, the safer the process will be.
What is needed, then, is an improved faceshield for cycle helmets that allows the rider to wear goggles underneath the shield as a second layer of mud-proofing, and further makes the opening of the faceshield quicker and easier than the conventional manually-operated shield.
SUMMARY OF THE INVENTIONIn light of the aforementioned problems associated with the prior devices, it is an object of the present invention to provide an Anti-fouling Faceshield. The faceshield should attach to a conventional motorcycle helmet. The faceshield should be particularly suited to competitive dirtbike racing where large amounts of mud are thrown onto riders' goggles in a short period of time. It should be spring-loaded so that the rider need simply pull a release lever to cause the faceshield to flip up and away from the face opening of the helmet. The main faceshield should further have an upper shield extending upwardly from it to protect the pivot point/hinge area of the mechanism from being fouled with mud and other foreign bodies.
The objects and features of the present invention, which are believed to be novel, are set forth with particularity in the appended claims. The present invention, both as to its organization and manner of operation, together with further objects and advantages, may best be understood by reference to the following description, taken in connection with the accompanying drawings, of which:
The following description is provided to enable any person skilled in the art to make and use the invention and sets forth the best modes contemplated by the inventor of carrying out his invention. Various modifications, however, will remain readily apparent to those skilled in the art, since the generic principles of the present invention have been defined herein specifically to provide an Anti-fouling Faceshield.
The present invention can best be understood by initial consideration of
The faceshield 20 is comprised of two main elements—the main mudshield 22, and the upper mudshield 24. The main mudshield 22, like a conventional faceshield, is made from shatter-proof, clear plastic. The upper mudshield 24 is either bonded to, or molded as a single piece of, the main mudshield 22. The upper mudshield 24 may or may not be made from the same material as the main mudshield—since the upper mudshield 24 is not in the rider's line of sight, it is unnecessary that it be transparent. Manufacturing efficiency, however, may dictate that identical materials (to the main shield) be used. If we now turn to
The upper mudshield 24 is positioned very specifically to cover the visor 14 when the shield 20 is either in the “up” or the “down” position. The purpose of this positioning is to cover and protect the operating mechanism of the actuating mechanism (see
In its preferred form, the main mudshield 22 will be somewhat angular in shape. There is a front member 32 which comprises the main viewing panel through which the rider sees. There are also a pair of opposing side members (e.g. 34A) extending backwardly from the front member 32. The pivot point 26 is a hinge device between the top edge of the front member 32 and the underside of the helmet visor (see
The faceshield 20 has a pair of apertures (e.g. 40A) on the upper portions of each side member 34A, 34B. First and second ends 46A and 46B of transverse shield strut (see
The actuating mechanism 28, only partially depicted here in order to orient it with respect to the shield 22 without obscuring critical elements, includes a mounting bracket 48 attached to the underside of the helmet visor (see
The release axle 50 is retained in position by the mounting bracket 48, which is attached to the underside of the helmet visor, but is allowed to rotate therein. At the end of the axle 50 opposite to the release lever 52 is a retaining finger 53. The retaining finger 53 is oriented and shaped such that it can grasp the transverse shield strut 44 when the finger 53 is in the position shown.
Once released from the retaining finger 53, the strut 44 will be free to move in the direction of a biasing force created by a pair of springs (see
Those skilled in the art will appreciate that various adaptations and modifications of the just-described preferred embodiment can be configured without departing from the scope and spirit of the invention. Therefore, it is to be understood that, within the scope of the appended claims, the invention may be practiced other than as specifically described herein.
