This invention relates to a device and system for preventing annoying and/or harmful insects such as mosquitoes and bees from entering the vent openings provided in sports helmets and other related occupational protective helmets. The invention is particularly geared to cycling helmets but is not limited to such cycling helmets. Cycling helmets normally include an outer protective shell of relatively thick-engineered plastic material with the shell of a generally concave shape to fit on the wearer's head while cycling. An inner web structure to receive and cradle the user's head and provide adjustment means for variously sized wearer's heads is attached to the inner portions of the shell and normally spaced from the inner shell surface. Appropriate straps to secure and maintain the helmet in place during use are also of known conventional means such as nylon or polypropylene webbing.
When cycling and especially when the cyclist adopts a head down position on the cycle, the forward progress of the cycle places the helmet's vent openings directly in the path of airborne insects present in front of the cycle and may be driven or otherwise forced through the vent openings and thus access the user's head space causing a distraction to the cyclist. In the case of larger insects such as bees, the user or cyclist may likely suffer a bee sting. Such distractions could lead to cycling accidents and/or general annoyance to the safety and pleasure that cycling brings.
Accordingly, an object of the present invention is to provide a device and system to prevent insects from entering interior portions of a cycling helmet through the vent openings thereof.
A further object of the invention is to provide a device which can be easily fitted over the helmet and removed therefrom when the weather conditions, environment, etc. is such that insects are not present.
A still further object of the subject invention is to provide a device that can be fitted to or otherwise accommodate a wide variety of helmet sizes and shapes and which does not materially increase air drag when implemented.
These and other objects of the invention are accomplished by an insect prevention system in combination with a sports helmet of the type having an outer shell having one or more vents extending therethrough so as to permit air to pass therethrough to cool the helmet wearer's head, the helmet shell having a terminal peripheral edge including an inner surface adjacent to the terminal peripheral edge, comprising a covering adapted to overlie the helmet shell, said covering including a central open mesh portion of a fabric material having a first thickness and terminating in a peripheral edge portion of a materially greater thickness than the fabric material central portion, said covering peripheral edge portion adapted to engage the peripheral edge of the helmet shell with portions thereof extending upwardly into the shell and in contact with the inner surface of the shell adjacent the peripheral edge thereof.
Other objects, features and advantages of the invention shall become apparent as the description thereof proceeds when considered in connection with the accompanying illustrative drawings.
In the drawings which illustrate the best mode presently contemplated for carrying out the present invention:
Turning now to the drawings and particularly
The helmet's shell 14 is generally formed of engineered lightweight plastic material and includes one or more vent openings 20 that extend entirely through the shell 14 for the above stated purpose of allowing ambient air to pass therethrough to ventilate and cool the wearer's head 12. Usually vent openings 20 are located in the front portion 14A of the shell 14 as well as in the central portion 14B and the rear portion 14C. Ambient air enters the helmet's interior space 16 through the front and central portion openings 14A, 14B and exits (drag effect) through the rear portion openings 14C dependent to some extent on the attitude of the helmet determined by the wearer's riding position.
The helmet's shell 14 terminates in a terminal peripheral edge 18 that may be round, oval or of a somewhat irregular circumferential shape dependent on the helmet's design. The shell's interior space 16 further includes an inner surface portion 21 adjacent the terminal peripheral edge.
A covering 30 formed of a mesh material 32 is adapted to substantially overlie the entire exterior shell 14 surface. The covering 30 includes a top 33 and is generally cup-shaped and preferably is formed of an elastic material that can be stretched to a size large enough to fit over the entire shell 14. The covering 30 includes a peripheral edge band 34 of increased thickness which band 34 when positioned on the shell 14 passes over and contacts the shell's peripheral edge 18 and is adapted to overlie and contact the inner surface portion 21 of the shell 14. The band 34 provides both wear resistance to combat its repeated frictional contact with the edge 18 as well as to provide more heft or bulk for the user to grasp while stretching the band to fit such covering 30 over the helmet 10 as well as to provide tear resistance.
The band 34 may terminate in an enlarged elastic bead 36 to provide even greater strength and contact with the shell's inner surface portions 21. When utilizing the bead 36, the extent and thickness of the band 34 may be reduced or eliminated. The mesh material 32 defines a plurality of generally equally-spaced regular openings or holes of an extent small enough to prevent the particular or intended insect species desired to be excluded from passing through the vent openings 20 to the helmet's interior head space 16. Generally, the mesh material's openings or holes are sized to exclude the smallest sized insects such as mosquitoes but different mesh coverings having larger openings could be selected to only exclude larger insects such a bees.
Suitable materials for the covering 30 include commercially available stretch knit fabrics of the type utilized for pantyhose and therapeutic stockings. Such fabrics normally are tubular knitted and inherently provide a mesh-like construction which includes openings or holes the extent of which can be regulated by the knitting process. Such fabrics are stretchable and can include areas of reinforcing bands of thicker dimension than the main fabric extent. Generally, knitted fabrics inherently include an open mesh-like structure suitable for use in the present invention; however, woven fabrics or other fabrics produced by other processes such as flocking, etc. may be utilized in the construction of the covering 30 providing the desired open structure is achieved. U.S. Pat. No. 4,021,861 issued May 10, 1977 to Imboden et al and U.S. Pat. No. 8,468,856 issued Jun. 25, 2013 to Fukui provide general background material for producing pantyhose fabric. U.S. Pat. No. 6,886,367 issued May 3, 2005 to Mitchell et al shows how reinforcing bands of greater thickness than a main fabric body can be produced. The disclosures set forth in the above-indicated patents are hereby incorporated into the present application by specific reference thereto.
Fabric from a commercial pantyhose product, namely, readily available L'eggs everyday support denier 30 with the leg areas cinched together to form a pouch, was placed over and secured to a bicycle helmet to cover the vent openings 20 and the helmet 10 utilized in cycling along a section of a bike path with no bugs or other insects entering the helmet's head space 16 through vent openings 20 and with essentially no noticeable drag caused by the fabric.
An added feature of the covering 30 apart from the main objective of preventing insects from entering the helmet's interior through the vents is that when the covering 30 is positioned with its peripheral edges over the terminal rim of the helmet (tucked under as shown in

In contrast to the above, the
When not mounted on the shell in a use position, the covering 30 can be compacted and conveniently stored in the helmet's shell in either a pouch or compartment (see

However, such spacers are not needed when the form 66 is used to hold the barrier 60 in position because the form 66 inherently provides such needed space.

In addition, the compartment 74 may include a bottom closure in the form of a tab 76 formed of a plastic sheet material or a relatively stiff yet flexible fabric. The proximal end of the tab 76 is attached to the interior wall of the insert 70 as by adhesives, snap connectors, Velcro-type or other hook and loop fasteners or the like and extends over the open compartment bottom and is connected to the outer rear surface of the shell 10 via snap fasteners 78, 80 provided on the opposite tab end and shell outer surface respectively. In addition, such connection could be accomplished by utilizing Velcro-type or other hook and loop tape connectors or fasteners. The underside of the tab 76 is also preferably provided with means for attaching a portion, e.g., the bead 36, of the covering 30 thereto as by a Velcro-type strip 82. Thus, a portion of the bead 36 and/or band 34 of the covering 30 is attached to the strip 82 to center the covering vis-รก-vis the helmet 10. When the use of the covering 30 is needed or otherwise desired, the wearer can open the tab 76 and permit the covering 30 to simply drop down or out or manually dislodge the covering 30 and then grasp the peripheral portion of the covering 30 not attached to the tab 76 to pull the covering 30 up or otherwise position the covering 30over the helmet 10 to the active use position thereby preventing insects from passing through the vents. The upper portion of
