Breath deflector and method of use

Abstract

The present invention is a breath deflector apparatus and method of use. The apparatus comprises a breadth deflector preferably connected to a goggle frame, with the goggle frame being connected to an adjustable securement device that is adjustably connected to a preferably cold weather helmet. The breath deflector apparatus is preferably adjustable by twisting a knob mounted to the front of the helmet and is preferably adapted such that once adjusted, the breath deflector moves in synchronization or unison with the movement of a user's head within the helmet and thus prevents loss of securement and maladjustment of the breath deflector while using the breath deflector and during movement of the user's head.

Description

FIELD OF THE INVENTION

The present invention relates to breath deflectors, and in particular, to breath deflectors that provide for convenient secure adjustment while preventing fogging of a face shield.

BACKGROUND OF THE INVENTION

Various means are known in the art for securing breath deflectors, especially for use in combination with a cold weather helmet. However, such means have typically been awkward in use and once secured, do not necessarily remain secured and so not move well in synchronization with the wearer. Further, certain adjusting means or tensioning means are known in the art. Examples of breath deflector apparatuses and adjustment means are disclosed in the following list of US patents and applications, all of which are expressly incorporated herein by reference: U.S. Pat. No. 4,016,919 to Zmijewski, U.S. Pat. No. 5,046,492 to Stackhouse, U.S. Pat. No. 5,797,146 to Matich, U.S. Pat. No. 5,934,599 to Hammerslag, U.S. Pat. No. 5,956,119 to Gibbs, U.S. Pat.

SUMMARY OF THE INVENTION

The present invention is a breath deflector apparatus and method of use. The apparatus comprises a breadth deflector preferably connected to a goggle frame, with the goggle frame being connected to an adjustable securement device that is adjustably connected to a preferably cold weather helmet. The breath deflector apparatus is preferably adjustable by twisting a knob mounted to the front of the helmet and is preferably adapted such that once adjusted, the breath deflector moves in synchronization or unison with the movement of a user's head within the helmet and thus prevents loss of securement and maladjustment of the breath deflector while using the breath deflector and during movement of the user's head.

DETAILED DESCRIPTION OF THE INVENTION

Reference throughout this specification to “one embodiment,” “an embodiment,” or similar language means that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least one embodiment of the present invention. Thus, appearances of the phrases “in one embodiment,” “in an embodiment,” and similar language throughout this specification may, but do not necessarily, all refer to the same embodiment.

Furthermore, the described features, structures, or characteristics of the invention may be combined in any suitable manner in one or more embodiments. In the following description, numerous specific details are included to provide a thorough understanding of embodiments of the invention. One skilled in the relevant art will recognize, however, that the invention can be practiced without one or more of the specific details, or with other methods, components, materials, and so forth. In other instances, well-known structures, materials, or operations are not shown or described in detail to avoid obscuring aspects of the invention.

In order to facilitate the understanding of the present invention in reviewing the drawings accompanying the specification, a feature table is provided below. It is noted that like features are like numbered throughout all of the figures.

FEATURE TABLE
#	Feature	#	Feature
10	Breath deflector apparatus	20	Helmet
30	Goggle frame	40	Breath deflector
42	Mask	44	skirt
50	Adjustment knob	54	Cable spool
60	Cable	64	Cable housing
70	Pulley	76	Elastic cord

Referring now to the drawings, a first embodiment of breath deflector apparatus 10 comprises breath deflector 40, goggle frame 30, elastic cords 76, pulleys 70, helmet 20, cable 60 (or like suitable tether), cable housings (tubes) 64, cable spool 54, and cable adjustment knob 50 (or like suitable adjustment device). Breath deflector 40 preferably defines formed but flexible nose and mouth mask 42 having preferably fabric skirt 44 attached to a lower end thereof. Goggle frame 30 preferably defines the frame portion (preferably without the lens) of a conventional pair of goggles. Elastic cords 76 and pulleys 70 are conventional commercially available cords and pulleys. Helmet 20 preferably defines a cold weather helmet such as a snowmobile helmet. Cable 60, cable housings (tubes) 64, cable spool 54, and cable adjustment knob 50 are preferably taken from a commercially available “BOA Fit System” (BOA) such as are commercially available from Boa Technology, Inc. having a headquarters located in Denver, CO (see BOA Technology, Inc. website).

Breath deflector apparatus 10 is assembled such that an upper edge of breath deflector 40 is connected to a lower edge of goggle frame 30, a first elastic cord 76 is connected to a first side of goggle frame 30 on a first end and to a first pulley 70 on a second end, a second elastic cord 76 is connected to a second side of goggle frame 30 on a first end and to a second pulley 70 on a second end, cable housings 64 are mounted to the inside of helmet 20, cable spool 54 and cable adjustment knob 50 are rotationally mounted preferably to a front portion of helmet 20 (such as near the “mouth” area of helmet 20), and cable 60 is wound around cable spool 54, passed through cable housings 64, and around both of pulleys 70.

In practice, a user dons helmet 20 and positions breath deflector 40 near his eyes, nose, and mouth with deflector skirt 44 preferably removably attached (e.g. via a hook & loop connection) to a forward portion of helmet 20. The user then rotates cable adjustment knob 50 in a tightening direction (which causes a payout length of cable 60 to decrease) such that breath deflector 40 comes to a comfortably snug contact to the user with elastic cords 76 being somewhat stretched. With breath deflector apparatus 10 so adjusted, the user can breathe while wearing the breath deflector apparatus without fogging a face shield of helmet 20, as the user's breathe is channeled away from a face shield of helmet 20. Moreover with breath deflector apparatus 10 so adjusted, the user may turn or move his head and the breath deflector remains in comfortably snug contact to the user even if there is some relative movement between the user's head and helmet 20. This is in distinct contrast to conventional breath deflectors which are readily dislodged or misadjusted when there is relative movement between the user's head and a helmet. Further, when a user desires to remove helmet 20, the user need merely pull out on adjustment knob 50 which allows tension in cable 60 to be relaxed (and causes a payout length of cable 60 to increase) such that breath deflector 40 is loosened from snug contact to the user. The user can then remove helmet 20 without necessarily removing goggle frame 30 from helmet 20. This is in distinct contrast to conventional goggles (which have a stretchable retention band) which must first be removed before a helmet may be removed.

In an alternate embodiment, breath deflector apparatus 10 is substantially identical to the preferred embodiment except that goggle frame 30 includes a lens therein. The lens may be a prescription or a non-prescription lens and may be a clear or a tinted lens. Goggle frame 30 may be specifically adapted so as to readily substitute one lens type for another lens type in goggle frame 30.

The present invention may be embodied in other specific forms without departing from its spirit or essential characteristics. The described embodiments are to be considered in all respects only as illustrative and not restrictive. The scope of the invention is, therefore, indicated by the appended claims rather than by the foregoing description. All changes which come within the meaning and range of equivalency of the claims are to be embraced within their scope.
