Summary of the Invention
Flashlights are commonly employed in emergency situations where some sort of repair is being made. Therefore, one frequently wishes to place a flashlight in a stationary position where it will illuminate a particular area, thereby leaving both hands free to effect the desired repair. However, a great number, if not a majority of flashlights are manufactured in a cylindrical barrel shape. When placed on a flat surface, such as a table, such flashlights have a pronounced tendency to roll out of the desired position.
Accordingly, one object of the present invention is the provision of an anti-roll and positioning device that can be attached to a flashlight or the like that has a substantially cylindrical body and that will substantially prevent, or at least minimize, the tendency of the flashlight to roll out of a position in which it has been placed.
Another object of the invention is the provision of an anti-roll and positioning device that can be attached to a flashlight or the like with a minimum of effort.
Yet another object of the invention is the provision of an anti-roll and positioning device that will simultaneously permit the flashlight to be even more positively positioned on ferrous objects.
A further object of the invention is the provision of such an anti-roll and positioning device in at least two versions, one version for flashlights of relatively large size, and one version for flashlights of smaller dimensions.
A still further object of the invention is the provision of such an anti-roll and positioning device that is simple in construction and operation and that can, therefore, be inexpensively fabricated.
In one aspect, the invention generally features a positioning device for a flashlight and the like having a substantially cylindrical body portion, the positioning device including: an annular member having an interior opening passing therethrough; the interior opening being dimensioned to at least partially encircle the substantially cylindrical body of the flashlight; the annular member having an exterior surface opposing the interior opening; and at least one substantially planar surface provided on the exterior surface of the annular member.
Preferably, the annular member includes a magnetized plastic material; and the at least one substantially planar surface includes at least six substantially planar surfaces provided on the exterior surface of the annular member; or the at least one substantially planar surface includes at least five substantially planar surfaces provided on the exterior surface of the annular member.
In another aspect, the invention generally features a positioning device for a flashlight and the like having a substantially cylindrical body portion, the positioning device including: an annular member having an interior opening passing therethrough; the interior opening being dimensioned to at least partially encircle the substantially cylindrical body of the flashlight; the annular member having an exterior surface opposing the interior opening; and at least six substantially planar surface provided on the exterior surface of the annular member; the six substantially planar exterior surfaces being spaced substantially equally about the exterior surface of the annular member.
Preferably, the annular member includes a magnetized plastic material; the six substantially planar surfaces are all substantially identical in configuration when viewed in plan; and the exterior surface of the annular member includes a hexagonal configuration when viewed in elevation.
In another aspect, the invention generally features a positioning device for a flashlight and the like having a substantially cylindrical body portion, the positioning device including: an annular member having an interior opening passing therethrough; the interior opening being dimensioned to at least partially encircle the substantially cylindrical body of the flashlight; the annular member having an exterior surface opposing the interior opening; and at least five substantially planar surface provided on the exterior surface of the annular member, the five substantially planar exterior surfaces being spaced substantially equally about the exterior surface of the annular member.
Preferably, the annular member includes a magnetized plastic material; the six substantially planar surfaces are all substantially identical in configuration when viewed in plan; and the exterior surface of the annular member includes a pentagonal configuration when viewed in elevation.
The invention will now be described by way of a particularly preferred embodiment, reference being made to the accompanying drawings, wherein:

Description of the Preferred Embodiment
Referring initially to FIGS. 1, 3, 5, and 6, a first embodiment of an anti-roll and positioning device 10 constructed according to the present invention is designed for attachment to a flashlight 12, the flashlight 12 being of relatively large size. The anti-roll and positioning device 10 generally includes an annular member 14 having an opening 16 passing therethrough. Preferably, the opening 16 is of generally circular configuration when the annular member is viewed in front elevation, as shown in FIG. 6, and the opening 16 thus accommodates the insertion of a generally cylindrical barrel portion 18 of the flashlight 12 thereinto, as is seen most clearly in FIG. 3. Preferably, the opening 16 is dimensioned so as to rather snugly engage the periphery of the barrel portion 18 in a frictional fit.
The annular member 14 is preferably fabricated from a magnetized plastic material, a material which is well known in the art for its use in magnetic signs, etc. Use of a magnetized plastic material for the annular member 14 allows a flashlight fitted with the device 10 to be positively positioned on a ferrous surface by a magnetic coupling thereto, and additionally results in a relatively lightweight construction.
The annular member 14 has an exterior surface 20 opposed to the opening 16, and the exterior surface 20 is provided with at least one substantially planar surface 22 thereon. Preferably, as seen in FIGS. 1, 3, 5, and 6, the exterior surface 20 of the annular member 14 is, in the first embodiment of the invention illustrated in these figures, provided with six such planar exterior surfaces 22, the six planar exterior surfaces additionally preferably being of substantially identical configuration and equally spaced about the periphery of the annular member 14, such that the exterior surface 20 of the annular member 14 presents a hexagonal configuration when viewed in elevation, as is shown most clearly in FIG. 6.
A second embodiment of an anti-roll and positioning device constructed according to the invention that is designed for flashlights of relatively smaller dimensions is shown in FIGS. 2, 4, 7, and 8. Like reference numerals are employed below to refer to similar elements already described above, any differences in construction being specifically noted.
In this second embodiment of the invention, only five planar surfaces 22 are disposed about the exterior surface 20 of the annular member 14, all of the five planar surfaces 22 again being preferably of substantially identical configuration and equally spaced about the periphery of the annular member 14, such that the exterior surface 20 of the annular member 14 presents a pentagonal configuration when viewed in elevation, as is shown most clearly in FIG. 7. Again, the opening 16 through the annular member 14 is preferably dimensioned so as to rather snugly engage the periphery of the barrel portion 18 in a frictional fit.
The use of either five or six planar surfaces 22, depending upon the relative size of the flashlight or the like to which the device 10 is being attached, provides for better stability, particularly with smaller diameter flashlights.
With the positioning device 10 attached thereto, the flashlight 12 may nonetheless still be inserted into a holster.
While the invention has been herein described by way of a number of particular preferred embodiments, various substitutions of equivalents may be effected without departing from the spirit and scope of the invention as set forth in the following claims.
