ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates generally to flashlights and fixture for use with the mouth, especially for use in holding objects in the mouth, and more particularly to a sleeve adapted for holding a flashlight by the mouth.
2. Description of Related Art
The following art defines the present state of this field:
Churchill, U.S. Des. Pat. No. 332,500 describes a mouth supported flashlight design
DeGuevara, U.S. Des. Pat. No. 302,334 describes a mouth supported holder for a flashlight design.
Colby, U.S. Pat. No. 2,244,288 describes A flashlight holder comprising a cap, a threaded lining of current conducting material in the cap and adapted to be screwed on one end portion of a flashlight for removably mounting said cap thereon, an integral, substantially T-shaped bit projecting longitudinally from the cap, said bit adapted to be gripped between the teeth, and an integral brace depending from the cap and engageable with the chin for assisting in supporting the flashlight in a forwardly projecting position. The brace provides an opening for the reception of a support for hanging the flashlight.
Sedlock, U.S. Pat. No. 3,418,461 describes a flashlight embodying an elongated barrel-like battery containing casing having an illuminable lens at a forward end and a closing cap at a rearward end, and self-contained readily applicable and removable flashlight positioning, supporting and light beam directing attachment means embodying an adapter clamp comprising a resilient hand-type C-clamp snugly but yieldingly and adjustably embracing a portion of said casing adjacent said rearward end, a complemental support bracket, said bracket being generally L-shaped in edge elevation and embodying companion legs disposed at right angles to each other, one leg being of a predetermined length, width and crosssectional dimension and having a right angularly bent free end portion arcuately bent and superimposed upon and affixed to a median crest potion of the outer peripheral surface of the bight portion of said C-clamp whereby said one leg is radial to and flush with a rearward marginal edge of said clamp, the other leg being at right angles to said one leg and adapted to assume a plane parallel to the longitudinal axis of said casing and being wholly and protectively enclosed in a permanently attached compressibly resilient sleeve, and said sleeve being formed at an outer free end portion with an enlarged retaining anti-slipping bead fashioned into and providing a contoured conveniently grippable mouthpiece which when in use is adapted to be clenched and held between the user's teeth.
Feilmeier, et al., U.S. Pat. No. 5,063,483 describes a battery powered light with mouthpiece including the combination of an illuminating means and a mouthpiece. In use, a user can hold the illuminating means by gripping the mouthpiece and direct the light source in a particular manner. The combination of an illuminating means and a mouthpiece permits the illuminating means to be used while the hands of a user are free to perform specific tasks.
Lucas, U.S. Pat. No. 5,226,712 describes A flashlight having a main body with a light emitting source at a distal end thereof powered by a battery power source within the main body and a switch at an opposite proximal end encapsulated within a resilient switch jacket defining an oral grasping portion adapted to be held between a user's upper and lower front teeth such that a biting force exerted thereon serves to operate the switch between an open position and a closed position. The proximal end of the main body is sized and configured to prevent accidental, forced entry of the flashlight into the user's oral cavity during use. A neck strap attached at opposite ends to the main body allows the flashlight to be hung about the user's neck in a readily accessible orientation.
Malley, U.S. Pat. No. 5,473,520 describes a flashlight holding mouthpiece, which consists of a receptacle portion adapted to grippingly embrace the rear end of an associated miniature flashlight and an outwardly projecting flange portion, the entire mouthpiece, including the receptacle portion and the flange portion, being a unitary body of resilient material. In a first embodiment of the invention the flange portion is small enough to be received between the user's teeth and lips. In the second preferred embodiment the flange portion is large enough to protect the user's lips from coming in contact with the metal barrel of the miniature flashlight.
Zolninger, U.S. Pat. No. 5,485,357 describes a flashlight with mouth support and associated controls including a flashlight having a forward end with a bulb, a rearward end with a separable cap with a spherical recess and an intermediate cylindrical extent therebetween. A mouthpiece is fabricated of an elastomeric material with an arcuate inner surface adapted to be supported by the teeth of a user and an enlarged external surface positionable between the teeth and lips of the user and a central post extending forwardly thereof. An electrical coupling between the mouthpiece and the flashlight includes a central axial aperture extending from the flashlight to the cap and to an intermediate section of the mouthpiece with electrical wires extending therethrough.
Morgan,. U.S. Pat. No. 6,170,787 describes an expandable cup holder for a golf cart including a support member forming a substantially planar top surface for the cup holder. The support member is fastened to a vehicle with the support member top surface oriented substantially horizontal. The top surface forms a top aperture large enough to receive a plurality of cup sizes. A plurality of flexible fingers are spaced apart from each other around the perimeter of the aperture. The fingers extend conically downwardly toward each other below the top surface, to form a slotted, frustum-shaped member that flexibly contacts and frictionally retains a plurality of cup sizes therein. Front and side walls on the support member surround and support the frustum-shaped member. The front wall includes apertures for retaining golf tees.
The prior art teaches flashlights adapted for being held by mouth and adaptors for being used with a flashlight to enable the flashlight to be held by mouth. The prior art devices teach that a flashlight should be held by its rear end, and all of the adaptations to flashlight cases and all of the flashlight adaptors for holding the flashlight are fixtured at the rear end of the flashlight. In contrast to this teaching, the present invention teaches away; that is, for holding the flashlight medially by the teeth. To accomplish this, the present invention teaches a sleeve that is comfortable to be held by the teeth and adjusts to hold flashlights having a range of sizes, in a simple extruded part. The present invention provides these and further related advantages as described in the following summary.
SUMMARY OF THE INVENTION
The present invention teaches certain benefits in construction and use which give rise to the objectives described below.
A lighting device includes a tubular flashlight with a barrel of a size and shape selected from a range of such sizes and shapes, and a sleeve of uniform cross-section. The sleeve has a through aperture into which the flashlight barrel is engaged with a forward end and a rearward end of the barrel extending from the sleeve. An inside surface of the aperture has longitudinal resilient ribs. The ribs are of a shape, size, spacing and resiliency as to enable tight gripping of the ribs on the barrel. The barrel size may be selected from a range of barrel sizes as, when inserted into the sleeve, the ribs are flexible enough to resiliently crush and thereby grip the barrel more securely and enable both small and large barrels to be gripped. In use, the sleeve is place about the barrel of the flashlight and slid to a medial position on the barrel. The flashlight, with the sleeve in place, is then placed into the mouth with the teeth in contact on opposing sides of the sleeve. The sle
