Description
CROSS-REFERENCE TO RELATED APPLICATIONS
[0001] This application claims priority, in part, to U.S.
Provisional Application No. 60/952,756 filed Jul. 30, 2007.
FIELD OF INVENTION
[0002] This invention relates generally to the field of protective
sports equipment for a cycle rider, and specifically an accessory
for a cycle helmet to protect a rider's face from insects and
debris.
BACKGROUND OF THE INVENTION
[0003] It is well known in the art for motorcyclists to use helmets
with face shields. Motorcycle helmets commonly include some sort of
face shield to protect motorcycle riders (i.e., an enclosed helmet,
a full face guard, or a partial face guard). However, the use of
helmets by cycle riders has only relatively recently become
common.
[0004] Cycle safety helmets are commonly molded with a hard plastic
material having an inner close fitting foamed polymer liner. In
case of an accident, the helmet is capable of withstanding the
shock loads by the hard plastic shell of the helmet along with the
resilience in the foam lining so that the force of the impact is
distributed over a wider area to reduce the dangers of concussion
and other head injuries. Indeed, the wearing of a regulation
cycling-helmet of some type is now mandatory in many states. Thus,
cyclists are becoming more accustomed to the use of helmets.
[0005] However, cycle helmets do not typically include face
shields. Moreover, purchasers of cycle helmets may vary in their
preferences as to whether or not they would like to wear a face
shield.
[0006] It is thus desirable to have a face shield that is
selectively attachable to a cycle helmet and which can be securely
attached to a helmet without remanufacturing or specialized tools
or processes, and which is proportioned to be used on helmets of
varying sizes and shapes.
[0007] It is further desirable to have a face shield which can be
inexpensively, safely and reliably manufactured and that such
method of manufacture result in a device which will not impact the
user's peripheral vision.
[0008] It is also desirable to have a flexible face shield which
can be adapted to various size helmets and withstand the impact of
the wind when a cycle is in motion, which allows the passage of air
through the structure and which retains its shape and position
under such conditions.
SUMMARY OF THE INVENTION
[0009] It is an object of this invention to provide a cycle face
shield for selective attachment to a cycle helmet which allows air
to pass through the shield without obstructing a cyclist's view or
affecting the cyclist's peripheral vision.
[0010] It is further an object of this invention to provide a cycle
helmet and face shield protection system comprising a cycle helmet
and a mesh face shield adapted for selective attachment to the
helmet, using a method of manufacture which results in economic
replication of a device with minimal "bleeding" of the molded
material onto the viewable surface of the shield ("acceptable bleed
rate").
[0011] The invention can be adapted for varying size helmets, and
for male, female and adult helmet proportions. It may also be
constructed of varying sizes of mesh (weave density) to provide
varying levels of air flow and protection from insect and
debris.

GLOSSARY
[0017] As used herein, the term "helmet" refers to any head
covering worn by a cyclist, regardless of the material, the extent
of the head/face covered, and whether it contains aerodynamic
features.
[0018] As used herein, the term "mesh" means a material constructed
of a material having the appearance of a net through which air can
pass, but which impedes the passage of bugs and debris. As used
herein, mesh refers to any netting, screen or mesh-like material
having any weave density or proportion known in the art and
typically associated with mesh. Mesh may be constructed from
plastic, cloth, metal alloys, aluminum or any other material known

affixing a face shield to a cycle helmet and may include Velcro,
adhesive, adhesive strips, snaps, hooks, bolts, welding, heat
sealing, single molding design, contouring, suction, screws,
specially constructed components to fit within corresponding
apertures or any other means of attachment known in the art.
[0024] As used herein, the term "arcuate" means curved or
contoured, for example to complement the shape of a helmet or
dimensions of a user's face, or to overcome wind resistance.
[0025] As used herein, the term "anthropometrically" means in
accordance with or taking into account human proportions (e.g.,
male, female, adult, child) in a design, particularly with respect
to the proportions of the face and head.
[0026] As used herein, the term "non-visible surface" means the
surface of a face shield which faces inwardly toward the user's
face.
DETAILED DESCRIPTION OF EMBODIMENTS OF THE INVENTION
[0027] For the purpose of promoting an understanding of the present
invention, references are made in the text hereof to embodiments of
a cycle face shield, only some of which are depicted in the
figures. It should nevertheless be understood that no limitations
on the scope of the invention are thereby intended. One of ordinary
skill in the art will readily appreciate that modifications such as
the dimensions, size, and shape of the components, alternate but
functionally similar materials (e.g., mesh) from which the cycle
face shield is made, and the inclusion of additional elements are
deemed readily apparent and obvious to one of ordinary skill in the
art, and all equivalent relationships to those illustrated in the
drawings and described in the written description do not depart
from the spirit and scope of the present invention. Some of these
possible modifications are mentioned in the following description.
Therefore, specific details disclosed herein are not to be
interpreted as limiting, but rather as a basis for the claims and
as a representative basis for teaching one of ordinary skill in the
art to employ the present invention in virtually any appropriately
detailed apparatus or manner.
[0028] It should be understood that the drawings are not
necessarily to scale, emphasis instead being placed upon
illustrating the principles of the invention. In addition, in the
embodiments depicted herein, like reference numerals in the various
drawings refer to identical or near identical structural elements.
For example the face shield described herein may be of varying
shapes and proportions to accommodate various size users and
helmets and levels of wind resistance, and to accommodate users
wearing glasses or other facial accessories.
[0029] Moreover, the term "substantially" or "approximately" as
used herein may be applied to modify any quantitative
representation that could permissibly vary without resulting in a
change in the basic function to which it is related. For example,
one embodiment of the cycle face shield is disclosed herein as
being oriented substantially parallel to a cyclist's face when
secured to a cycle helmet and worn. The cycle face shield might
permissibly be oriented substantially non-parallel to the user's
face when secured to a helmet and worn by the cyclist and still be
within the scope of the invention if its functionality is in a non
parallel not materially altered.
[0030] Referring now to the drawings, FIG. 1 shows a side view of
cyclist 50 wearing one (1) embodiment of cycle helmet 55 with cycle
face shield 100 attached thereto. As can be appreciated, cycle
helmet 55 is temporarily secured to cyclist's 50 head 52 by chin
strap 56, and cycle face shield 100 is secured to the front of
cycle helmet 55 to protect the face of cyclist 50.
[0031] FIG. 2 shows a top perspective view of the embodiment of
cycle face shield 100 secured to cycle helmet 55 shown in FIG. 1.
As can be appreciated, cycle face shield 100 is secured to forward
portion 59 of cycle helmet 55 to protect a cyclist's face (not
shown). In the embodiment shown, cycle face shield 100 is made of a
substantially rigid mesh 105 shaped by die-cutting or any other
method, and may be a plastic or metal mesh sealed with a
thermoplastic elastomeric rubber a to create frame 110 which seals
the ends of the mesh. In the embodiment show, face shield 100 is
affixed to cycle helmet 55 by adherent 60, which in the embodiment
shown is a set of complementary adhesive-backed Velro strips. In
such an embodiment, cycle face shield 100 protects the cyclist's
forehead, eyes, ears cheeks, nose, and chin. However, it should be
understood that alternate embodiments of cycle face shield 100
could extend lower (See FIG. 3) to protect the cyclist's ears, neck
and throat and/or outward to provide some protection to the
cyclist's ears of speeds of between four and forty miles per
hour.
[0032] In the embodiment shown adherent 60 are Velcro strips having
a non water-soluble adhesive backing. In the embodiment shown, the
Velcro strips used as adherent 60 are approximately one to one
inches wide by 6-8 inches and of sufficient flexibility to
accommodate varying sizes of helmets, and helmet contours, while
providing a sufficient adhesive surface to withstand winds of up to
40 mph on a bicycle helmet and substantially higher speed for
motorcycles.
[0033] In various other embodiments, adherents may include adhesive
strips, snaps, hooks, bolts, welding, heat sealing, single molding
design, contouring, suction, screws, specially constructed
components to fit within corresponding apertures or any other means
of attachment known in the art.
[0034] In the embodiment shown, face screen 100 is created by
suspending die-cut mesh 105 in an injection mold, into which
polyolefin elastomeric (Thermoplastic Elastomer) or any other
material known in the art having an acceptable bleed rate is
injected to form frame 110 which seal the mesh fiber ends of mesh
105 and prevents them from irritating a user's face. The fibers of
the mesh are vertically suspended within a mold, and centered to
minimize the bleed rate during the injection process, and minimize
the movement of the fibers within the frame. The mesh ends are
sealed and coated within the molded frame to prevent movement of
the fibers and protect a users face from the ends of the
fibers.
[0035] The cycle face shield is desirably formed of a single
molding process having an acceptable bleed rate (i.e., the amount
of plastic which leaches or escapes from a defined mold cavity
during the manufacturing process), e.g., of no more than 0.1
cm.
[0036] This embodiment of cycle face shield 100 is substantially
flat vertically, but has in other embodiments could be sloped or
have an arcuate curve. It should be understood that cycle face
shield 100 can be rigidly constructed and custom-curved for a
specific make and/or model of cycle helmet 55, or cycle face shield
100 can be somewhat flexible, allowing it to be bent horizontally
vertically or horizontally for use with a variety of cycle helmets
55, and for users having adult, juvenile, male or female
anthropometric proportions. Further alternate embodiments of cycle
face shield 100 can be more or less horizontally arcuate along
arrow A, be multi-faceted, or be substantially flat.
[0037] In the embodiment shown, cycle face shield 100 has tapered
edges 69a and 69b, and flattened edge 71 to minimize wind
resistance and conform. In the embodiment shown, edges 69a and 69b
are tapered at an approximate 12-20 degree angle. The embodiment of
cycle face shield 100 shown in FIG. 3 is secured to cycle helmet 55
by a Velcro.TM. strip 60, thus creating a selectively removable,
attachment of cycle face shield 100 to cycle helmet 55, whereby the
face 100 can be disengaged by separating the complementary Velcro
strips.
[0038] FIG. 3 shows an alternate embodiment in which cycle face
shield 100 is permanently secured to cycle helmet 55 via apertures
55a, 55b and 55c created during the molding process. Other
embodiments may have varying numbers, shapes and sizes of apertures
for affixation. Thus, it should be understood that cycle face
shield 100 can be secured to cycle helmet 55 by any mechanism known
and commonly used in the art, including but not limited to snaps,
an adhesive, a hook and latch mechanism, buttons, the use of one
(1) or more hooks on either cycle helmet 55 or, cycle face shield
100 and corresponding apertures on the other, or a band that
encircles cycle helmet 55.
[0039] Furthermore, the mechanism by which cycle face shield 100 is
secured to cycle helmet 55 should not be limited to any particular
number of attachment points. For example, the embodiment of cycle
face shield 100 shown in FIG. 2 is secured to cycle helmet 55 by
four (4) Velcro.TM. strip 60, but can be secured by any number of
Velcro.TM. strip 60. It should also be understood that the same is
true for the other attachment mechanisms, whether permanent or
temporary.
[0040] The embodiment of cycle face shield 100 shown in FIGS. 1
through 2 is made of a substantially clear and rigid or semi metal
or plastic mesh plastic which air allows air to pass through. This
provides sufficient protection against dirt, debris, and insects
for the cyclist as well as not obstructing the cyclist's view and
permitting air flow. It also allows easy cleaning of cycle face
shield 100. However, one of ordinary skill in the art that other
materials that provide similar advantages and have similar
characteristics can be used so long as the materials are
substantially clear to permit ease of viewing through cycle face
shield 100.
[0041] FIG. 4 shows a top perspective view of an alternate
embodiment of cycle face shield 100 secured to cycle helmet 55. In
the embodiment shown, cycle face shield 100 is aerodynamically
shaped to minimize wind resistance, being wider at the top and
tapered on the sides. In other embodiments, faces shield 100 may be
of varying dimensions to accommodate male, female, adult and
juvenile uses and/or to provide additional protection for the
cyclist's neck. FIG. 4 shows tapered edges 69a and 69b, and
flattened edge 71 which is narrower than upper edge 73 to minimize
wind resistance and conform. In the embodiment shown, edges 69a and
69b are tapered at an approximate 12-20 degree angle.
[0042] In the embodiment shown in FIG. 4, cycle face shield 100 is
made of a die cut me metallic mesh 105 which has been suspended in
a plastic injection mold into which plastic as been injected to
seal the ends of the mesh and create a frame 110. In the embodiment
shown, the acceptable bleed rate from the frame portion of the mold
is no more than 0.1 cm. The aerodynamic design of the face shield
allows the face shield 100 to hang vertically whether the cyclist
is looking forward or downward. Such a construction will also
provide greater comfort for some users. In this embodiment the mesh
is clear in color, but in other embodiments the mesh may be of
another color or may be constructed of aluminum, plastic, carbon
fiber, fiber glass, polymer, resin, metal or any other substance
capable of being formed into a lightweight mesh which may be
attached to a cycle helmet.
[0043] In still other alternate embodiments of cycle face shield
100, cycle face shield 100 can extend substantially around the
sides of cycle helmet 55 or even extend entirely around cycle
helmet 55. Such an alternate embodiment of cycle face shield 100
will provide additional protection to the cyclist's ears and/or
back of the neck. Especially for those embodiments of cycle face
shield 100 using the flexible mesh shown in and described with
respect to FIG. 3, such an embodiment will also provide protection
against insects.
[0044] While the cycle face shield has been shown and described
with respect to several embodiments and uses in accordance with the
present invention, it is to be understood that the same is not
limited thereto, but is susceptible to numerous changes and
modifications as known to a person of ordinary skill in the art,
and it is intended that the present invention not be limited to the
details shown and described herein, but rather cover all such
changes and modifications obvious to one of ordinary skill in the
art.
[0045] In the embodiment shown, face shield mesh 105 is constructed
from a coated aluminum screen cloth known in the art as Goldstrand,
but may be constructed of any other material such as plastic,
rubber, resin, metal alloys, fabric or other metals. For example,
ingredients such as chromium, magnesium, and manganese may be added
or used in any proportion.
[0046] Various exemplary embodiments may have a frame constructed
of a clear or visually minimized frame 110, with approximate
dimensions of one-fourth to one-eighth inch, sealing the edges of
the mesh and one or more bonded layers of mesh, Velcro.TM., labels
or other layers of materials at the top and sealing or locking the
mesh ends together for strength and to prevent the user's face from
becoming scratched or irritated. A plastic, clear polymer or other
material capable of molding and sealing may be used.
[0047] In various embodiments mesh screen 105 alternately colored
aluminum mesh fibers, created by painting or screening or by
interweaving of alternately colored fibers, for example to create a
whimsical mask-like effect or holographic visual effect (not
shown).
[0048] FIG. 5 shows an alternative embodiment which includes
ornamentation 150 consisting of painting, screening and/or imaging.
Other ornamentation may include holographic images, phosphorescent
areas, sports logos, symbols, colors, objects, glow-in-the dark or
glitter effect. Ornamentation may be achieved a screening process,
painting, molding, machining or by affixing ornamentation with and
adhesive
