Description
Background of the Invention
This invention relates to lighting of the body attached type, and more particularly to a belt with an adjustable safety light.
Poor visibility is a serious problem at night for pedestrians, outdoor workers, and outdoor exercisers, such as joggers and the like. The difficulty of maneuvering oneself safely on foot on a roadway, field or yard is well known to walkers, joggers, police officers, firefighters, construction workers, railroad workers, and maintenance men, especially if the person is carrying something or working with their hands.
There have been many attempts to increase pedestrian visibility such as brightly colored and/or reflective clothing. However, little has been done to provide visibility for the pedestrian other than with hand-held flashlights. These are impractical and inconvenient for those wishing to keep their hands free or for use with other tasks.
Summary of the Invention
In view of the foregoing disadvantages inherent in the known types of devices now present in the prior art, the present invention provides a safety light belt. As such, the general purpose of the present invention, which will be described subsequently in greater detail, is to provide a light, attached to the person, which is adjustably aimed in front of the wearer downwardly at a point where he or she is about to step, forwardly and/or upwardly on a work piece or work area.
To attain this, the present invention provides a belt with an adjustable light holder mounted on the front thereof. A small light is mounted therein. The holder is so constructed that the light may be forwardly aimed upwardly, horizontally or downwardly of the belt wearer.
These together with other objects of the invention, along with various features of novelty which characterize the invention, are pointed out with particularity in the claims annexed hereto and forming a part of this disclosure. For a better understanding of the invention, its operating advantages and the specific objects attained by its uses, reference should be had to the accompanying drawings and descriptive matter in which there is illustrated a preferred embodiment of the invention.

Detailed Description of the Invention
Referring to the drawings in detail wherein like elements are indicated by like numerals, there is shown an embodiment of the invention 1 incorporating an adjustable safety light belt. The invention 1 is comprised of three elements, i.e., a belt 10, a holder 30, and a light housing 50. The belt 10 is attached around the trunk of a wearer (not shown) and is comprised of two pieces 15 and 16. The pieces 15, 16 each have an end 11 and 12, respectively, interconnected together with hook and loop fasteners 13 and 14. The other end 17, 18 of each piece 15, 16 is formed into a loop around side rings 36 attached to and positioned on either side 34 of a light holder 30. In another embodiment the belt 10 would be made of a single piece continuously threaded through the holder side rings 36 and across the back 31 of the light holder 30. Other type fasteners may also be used in place of the hook and loop fasteners described above, such as snaps, hooks, buckles, etc. The belt 10 in this embodiment is made of a sturdy "webbing" fabric, but other belt-like materials could also be used. A flat sponge may be attached to the back of the holder 30 for comfort.
The holder 30 in this embodiment has a generally rectangular shape and a preferred depth of one-half to one inch. Other dimensions and shapes could be used without deviating from the spirit of the invention. The holder 30 has a back 31, top 32, bottom 33, two sides 34, and a front 35. In this embodiment of the invention, the sides 34 are parallel to each other and perpendicular to the planes of the back 31, bottom 33 and top 32. A light housing assembly 50 with a light 51 contained therein is attached to a extension element 40 horizontally protruding from the front 35 of the holder 30.
Referring particularly to FIGS. 1, 6 and 7 the extension element 40 protrudes horizontally. The extension element 40 is formed into two flat, vertical prongs 48 (one shown), each having an external side 43, and has two ends, a holder end 41 and an extension end 42. The extension ends 42 are shaped into a semicircle and have a four open, radial notches 46 positioned with respect to a horizontal reference forward of the holder at +45 degrees, 0 degrees, -45 degrees and -90 degrees. At the approximate midpoint of the diameter chord line of the semicircle, an obtuse triangular opening 44 is formed along each extension element side 43. The corner of the triangular opening defined by the obtuse angle, the obtuse corner 45, is centered on the longitudinal axis of the extension element 40 and is the foremost point of the triangular opening 44. The side opposite the obtuse angle is formed into four open radial notches 47 corresponding in angular position to the extension element radial notches 46.
The light housing 50 has a conventional rounded shape with a light bulb 51 inserted into a conventional socket 52 contained therein. A transparent protective element 53 encloses the forward end of the housing 50. A horizontal extension element 54 is attached to the rear 55 of the housing 50. The extension element 54 has a central opening 56 for passage of wires 57 from the housing light socket 52. The extension element has two external sides 58 each containing two cylindrical, peg like protrusions 60, 61. The pegs 60, 61 are aligned horizontally along the central longitudinal axis of the extension element 54.
The Light housing extension element 54 is joined to the holder extension element 40 so that the housing extension 54 is positioned between holder extension element prongs 48. The housing extension element rearmost pegs, i.e., first pegs 60, are inserted into the obtuse triangular openings 44. The housing extension element foremost pegs, i.e., second pegs 61, remain forward of the holder extension element extension end 42. In operation the light housing 50 is pulled slightly forward away from the holder 30 and positioned at a desired angle. The light housing 50 is then pushed rearward toward the holder 30 wherein the first pegs 60 engage correspondingly positioned angular opening notches 47 and the second pegs 61 engage correspondingly positioned holder extension element angularly positioned notches 46. As stated above the notches 46 and 47 are open. However, the openings of both sets of notches 46, 47 are slightly less in dimension than the diameter of the pegs 60, 61. In effect, the light housing is "snapped" into a particular angular position.
The holder 30 is hollow and in this embodiment the holder interior is accessible via the top 32 which is substantially comprised of a snap-in cover 37 as illustrated in FIG. 4. Also in this embodiment, the light 51 is battery-powered. As is illustrated in FIG. 5 the batteries 6 are contained within the holder 30. The wires 57 from the light socket 52 within the light housing 50 are passed through the extension element central opening 56, between the holder extension prongs 48, through the holder front 35, and into the holder 30 for connection to the batteries 6.
It is understood that the above-described embodiment is merely illustrative of the application. Other embodiments may be readily devised by those skilled in the art which will embody the principles of the invention and fall within the spirit and scope thereof.
