Description




BACKGROUND OF THE INVENTION




a. Field of the Invention




The present invention relates to a support device for a self-powered illumination device. More specifically, it relates to a support and mounting device for a flashlight, which allows a flashlight carried by the device to be positioned to illuminate a desired area.




b. Discussion of the Prior Art




Heretofore, illuminating device supports encompassed many various designs, including wire racks, stationary tripods, stationary two legged supports, magnets, clamps, wire rings, and many other support configurations. U.S. Pat. No. 4,739,457 discloses a hands free illuminating device support having an adjustable light reflector. The support device allows an illuminating device to be prepositioned in a supported or suspended orientation. The support device is comprised of flanges attached to either side of the illuminating device casing and extending downward, terminating in a flange bottom edge. The flanges are configured to receive and latch the reflector into a stored position. Each flange also has a rotor shaft bearing to rotatably receive a rotor shaft on a Z-axis to the flange. This allows the rotor and a rigid leg attached to the rotor to have 360° of Z-axis rotation. The rotor has a rotor shaft and leg shaft bearings which rotatably receive the leg shaft on a Y axis to the flange, thereby providing the leg with about 180° of Y-axis rotation to the flange. The rigid legs have a leg shaft on one end and a hooking means on the opposite end. This allows the legs to be rotated, as required to accommodate the device to various detent positions on the Y and Z-axes to provide prepositioned support or suspension for the illuminating device held by the support device.




U.S. Pat. No. 5,743,623 shows a clip on support for a flashlight. U.S. Pat. No. 5,608,919shows a flashlight retainer that is flexible and has hooks for attaching it to a support. U.S. Pat. No. 5,016,148 teaches a flexible attached sleeve with support for a flashlight.




A commercially available product sold under the trademark “BENDYLIGHTS” has been found on sale during the week of Jun. 6, 1999. It consists of a cylindrical C-battery flashlight which is decorated with sunglasses/eyes on the head of the flashlight. It also includes a pair of bendable arms and legs in the form of caricature arms and legs, including an embedded bendable wire extending through each arm and leg. One wire joins both legs. One wire joins both arms. In both cases, the joining wires extend through the body of the flashlight and around the batteries. The BENDYLIGHTS products are integral with the body of the flashlight, and are not removable from the body of the flashlight.




None of the known prior art provides a simple device for supporting and mounting a flashlight, which device includes bendable appendages which are simply and easily rotated in the Y-axis and bendable in the X and Z-axis in order to allow a flashlight carried by the device to be positioned to illuminate a desired area




SUMMARY OF THE INVENTION




It is an object of this invention to provide a flashlight support device which may be prepositioned or repositioned to illuminate a desired area in a manner such that the device need not be hand held, thereby leaving the hands of a user free.




It is another object of this invention to provide such a flashlight support device having a single rotor mechanism and bendable appendages in order to reduce manufacturing costs.




It is also an object of this invention to provide such a support device of such diverse capability, and having bendable appendages so that a flashlight carried by the device may be supported, suspended or hung in almost ang position, regardless of the configuration or orientation of the area in which it is to be used, thereby increasing the utility of the flashlight carried by the device.




It is a further object of this invention to provide such a support device that is of such size and configuration that it offers no interference and does not add substantially to the size of the flashlight when it is hand held by a user.




It is still another object of the present invention to provide a support device for a flashlight that is of simple but rugged design, and which, at the same time, is very easy to operate.




These and other objects are provided by a flashlight support device having a hollow open body. The hollow open body has at least one open end and is designed and dimensioned to removably fit over the body of a flashlight. There is at least one pair of adjustable and bendable legs attached to the hollow body for rotation in the Y-axis. Each pair of adjustable and bendable legs is located in substantially diametric opposition adjacent to one open end of the hollow open body. Each leg is comprised of a bendable material and is capable of being bent, without any additional mechanism, into substantially any position and configurations in the X and Z-axis. A rotation mechanism and the adjustable and bendable legs attached thereto allows each rotatable and bendable leg to be rotated into a number of incremental positions, over a range of a full 360°. In preferred embodiments, the flashlight support device has two opposed open ends, and there are at least two pairs of adjustable and bendable legs attached to the hollow body by rotation means for rotation in the Y-axis and located in substantially diametric opposition to one another.




These and other objects of the present invention will become apparent to those skilled in the art from the following detailed description, showing the contemplated novel construction, combination, and elements as herein described, and more particularly defined by the appended claims, it being understood that changes in the precise embodiments to the herein disclosed invention are meant to be included as coming within the scope of the claims, except insofar as they may be precluded by the prior art.

DETAILED DESCRIPTION OF THE INVENTION




Referring now to

FIGS. 1-4

, the flashlight support device, generally


20


, of the present invention, is shown. Flashlight support device


20


includes a hollow, substantially cylindrical body or sleeve


22


. It is designed and dimensioned to removably fit over the cylindrical barrel of a hand held flashlight


24


, although other shapes and sizes may be used to accommodate flashlights having other shapes and sizes. Hollow cylindrical body


22


carries at least two adjustable legs or appendages


26


, although in the embodiments shown in

FIGS. 1-4

and


9




a


-


9




g


, and


10


-


12


it is shown carrying four rotatable and adjustable bendable legs


26


. As shown in

FIG. 1

, flashlight support device


20


is in the position and configuration that it will normally have when it is first produced, with two (2) pairs of straight legs


26


permanently, rotatably attached to sleeve


22


in a manner which is detailed below. A first pair of bendable legs


26


is located substantially adjacent to one open end of hollow, cylindrical sleeve


22


and diametrically opposed to each other, each leg being incrementally rotatably in the Y-axis using one of the mechanisms described below. A second pair of bendable legs


26


is located substantially adjacent to the other open end of hollow sleeve


22


and diametrically opposed to each other, again with each leg being incrementally rotatable in the Y-axis.




The flashlight support device of the present invention may have each rotatable and bendable leg


26


rotated into a number of incremental positions over a range of a full 360° in the Y-axis, and bent, without any additional mechanism, into substantially any position and configurations in the X and Z-axis. Representative examples of which, configurations are detailed below with reference to

FIGS. 2

,


3


and


9




a


-


9




g


. Now referring to

FIG. 2

, there is shown a perspective view of the flashlight support device


20


in repose, with all four legs


26


rotated and bent substantially parallel to cylindrical body


22


, this being the position in which device


20


will have legs


26


oriented when device


20


and flashlight


24


are being hand held or stored in a minimum of space. The friendly position shown in

FIG. 3

has all four legs


26


positioned in the same configuration and attitude so that a beam of light from flashlight


24


would be substantially parallel to the surface on which flashlight support device


20


is resting.




Now referring to

FIGS. 4-8

, additional details of flashlight support device


20


are shown. Each set of legs


26


includes a body portion


28


,

FIG. 8

, which carries a polygonal head portion


32


, and a foot portion


34


, in preferred embodiments head portion


32


and foot portion


34


are integral with body portion


28


. In preferred embodiments, body portion


28


is comprised of a wear resistant material, for example, polymeric thermoplastic nylon. As shown in

FIGS. 4 and 8

, body portion


28


is hollow, preferably carrying a polygonal cross section opening


36


, in this case having a square cross section. Opening


36


is accessible through polygonal head


32


. In preferred embodiments, located within each opening


36


is a bracing material


38


that is bendable, but which also provides strength to legs


26


. As with opening


36


, bracing material


38


is also polygonal, and in this case also has a square outer cross section. It has been found that the use of a polygonal opening


36


with a matching polygonal brace


38


provides a stable orientation between brace


38


and leg


26


. That is, when leg


26


is bent, it does not tend to rotate with respect to the outer polymeric portion of leg


26


. In use brace


38


is completely inserted within opening


36


of leg


26


, and runs axially substantially the entire length of leg


26


. In preferred embodiments, bracing material


38


is square 1008 low carbon steel wire, although any other metal, or shape retaining natural, or polymeric material may be substituted therefor. As a result, while the legs


26


are bendable and hold the desired shape and position in which the user places them, they are also very strong. This allows flashlight holder system


20


of the present invention, and the flashlight


24


which it carries to be positioned to shine, for example, from the substantially horizontal position shown in

FIG. 3

to a substantially vertical position as shown in

FIG. 9



a


, as well as at various other angles, or attached to various objects as shown in

FIGS. 9



a


-


9




c


and


9




e


and


9




f


. The forgoing not withstanding, the absence of any bracing material within legs


26


is within the scope of the present invention.




Hollow cylindrical body portion


22


is preferably comprised of a flexible material such as leather, rubber, fabric or polymeric material, with clear polyvinyl chloride being one preferred material. Hollow cylindrical body portion


22


carries one or two through holes


44


to receive legs


26


therethrough, while retaining polygonal heads


32


within its open hollow body, generally


46


. In order to accommodate heads


32


, hollow body portion


46


includes internal recesses


48


, see

FIGS. 5 and 7

. With polygonal heads


32


within internal recess


48


of body portion


22


, a retaining collar


52


is then inserted into open hollow body


46


and located to retain each head


32


in place within its recess


48


.




Referring now to

FIGS. 4

,


6


and


7


, it is seen that each collar


52


is cylindrical on the inside, and carries a pair of substantially flat, opposed outer support surfaces


54


, which each support surface


54


bearing against the substantially flat proximal end


56


of adjacent head


32


of leg


26


. Bracketing each support surface


54


is a pair of tab springs


58


. Tab springs


58


are separated by a distance that is substantially equivalent to the diameter through the center of polygonal head


32


to a pair of opposed sides of the polygon. As a result, when the head


32


is within recess


48


and secured against a flat support surface


54


, a pair of opposed polygonal sides of head


32


are normally retained in a stable position between tab springs


58


. However, when each leg


26


is rotated in the Y-axis, the flexible nature of head


32


or tab springs


58


allows head


32


or tab springs


58


to either deform or move over center so that an adjacent pair of opposed polygonal sides of head


32


may also assume a stable position between tab springs


58


. Rotation may proceed in any number of increments in either a clockwise or counter-clockwise direction. In the embodiment shown, polygonal head


32


has ten (10) sides, and therefore has ten (10) stable positions at incremental angles of about 36° of rotation in the Y-axis. It is of course clear that this system of rotation works most efficiently when polygonal head


32


has an even number of equilateral sides.




In preferred embodiments, collar


52


is normally rigid, but is deformable to the extent that if pressure is applied to it across its diameter, it will deform, and then return to its original shape, without either cracking or permanently deforming. One preferred material for use in forming collar


52


is transparent polycarbonate, which is deformable, but is also shatter resistant. Where head


32


is formed of nylon and collar


52


is formed of polycarbonate, since both materials have a high resistance to wear, and tend to provide low friction surfaces, both head


32


and collar tab springs


58


resist wear and have a long useful life. As detailed and shown below, each leg


26


can be rotated in ten (10) 36° increments in either direction for a total of 360°. It can be retained in any of the ten (10) incremental positions by the interaction of sides


56


of head


32


against tab springs


58


of collar


52


.




As shown in

FIGS. 4

,


6


and


7


, in preferred embodiments, collar


52


includes arcuate slots


62


into which labels


64


may be inserted. Labels


64


may carry trademark or trade name, or brand or grade or other information that allow the manufacturer/distributor to label the support system in an inexpensive, but permanent manner. In order to avoid damage to labels


64


, slots


62


are first sealed by the O-ring type fit between the inner surface of body


22


and slots


62


. They may be further sealed with a waterproof material, such as silicone sealant, in order to retain labels


64


in place while also sealing slots


62


so that water and other liquids cannot enter slots


62


and damage labels


64


.




It can therefore be seen that the versatile flashlight holder system


20


of the present invention expands the use of flashlight


24


. As shown by reference to

FIGS. 3

,


9




a


-


9




g


, it frees a users hands, for example, allowing the user to support and aim the flashlight from any surface to be shined at any angle or in any direction, attach the system to any support, including the user's belt, shirt, hat or other article of clothing. It allows the user to use one or more legs


26


to hang the system


20


, including flashlight


24


, in any convenient accessible location of preference by adjusting the angles of the legs


26


as desired. its uses are limited only by the imagination of the user. In addition, system


20


, and especially body portion


22


, protects the body of the flashlight


24


, and also provides a surface that can be gripped more securely than the body of the flashlight itself. Where the body portion


22


is clear or translucent, it enhances the visibility of the flashlight color, logo, trademark or other flashlight design feature. Nevertheless, system


20


is easily removed from or placed on the body of flashlight


24


.




Referring to

FIGS. 10

, there is shown an alternative embodiment of the support system


20


of the present invention in which the legs


26


terminate in rollers


74


. Similarly, referring to

FIG. 11

, there is shown another alternative embodiment of the support system


20


of the present invention in which the legs


26


terminate in an enlarged pad


84


. Pad


84


may either be a pad, a suction cup or may carry a magnetic. The utility of the embodiment in

FIGS. 10 and 11

, or of any other modified foot of leg


26


is apparent, and again, the variations to the foot are only limited by the imagination of the manufacturer. While the end of the leg may be formed into a hook, see

FIGS. 9



a


and


9




d


, it need not be in the form of a hook in order to function.





FIG. 12

shows the details of one alternative mechanism for connecting and positioning the base of a leg


26


for rotation in the Y-axis within the cylindrical body


22


of the support system


20


of the present invention. More specifically, as shown, modified head


132


of leg


26


carries a plurality of radially extending wedges


134


and grooves


136


spaced around its surface. Collar


152


carries a plurality of similarly sized and shaped complimentarily wedges


154


and grooves


156


radially around its surface. Wedges


154


and grooves


156


are located to receive and mate with wedges


134


and grooves


136


of modified head


132


. As a result, the series of wedges


134


and grooves


136


carried by head


132


are normally retained in a stable position against wedges


154


and grooves


156


of collar


152


. However, as with the previously described embodiment, when legs


26


are rotated in the Y-axis, wedges


134


and grooves


136


of head


132


move over center with respect to wedges


154


and grooves


156


of collar


152


. This allows head


132


and attached leg


26


to assume a plurality of stable incremental positions in the Y-axis. In the embodiment shown, head


132


has about twenty (20) pairs of wedges


134


and grooves


136


which intersect with a similar number of wedges


154


and grooves


156


carried by collar


152


. This embodiment therefore has twenty (20) stable positions at incremental angles of about 18° of rotation in the Y-axis.




In the alternative embodiment shown in

FIG. 12

, collar


152


is also normally rigid, but is deformable to the extent that if pressure is applied to it, it will deform, and then return to its original shape, without either cracking or permanently deforming. One preferred material for use in forming collar


152


is transparent polycarbonate, which, is noted above, is both deformable and shatter resistant. Where head


132


is formed of nylon and collar


152


is formed of polycarbonate, since both materials have a high resistance to wear, and tend to provide low friction surfaces, both head


132


and collar


152


resist wear and have a long useful life




Referring now to

FIG. 13

, it shows an alternative embodiment of the support system


20


of the present invention in which there are only two legs


26


which are located adjacent to the head of a flashlight


24


carried by support device


20


, with the rear end of flashlight


24


forming a stable tripod with legs


26


. As in the other embodiments, legs


26


are both rotatable in the Y-axis and bendable in the X and the Z-axis so that support device


20


of

FIG. 13

, and therefore, flashlight


24


can be positioned in substantially any orientation to point the beam of light were it is needed.




Similarly,

FIG. 14

shows another alternative embodiment of the support system


20


in which there are only two legs


26


which in this case are located adjacent to the front end of a flashlight


24


, with the end of flashlight


24


forming a stable tripod with legs


26


. As in the other embodiments, legs


24


are both rotatable in the Y-axis and bendable in the X and the Z-axis so that support device


20


of

FIG. 14

, and therefore flashlight


24


can be positioned in substantially any orientation to point the beam of light were it is needed.





FIG. 15

shows yet another alternative embodiment of the support system


20


in which the hollow cylindrical body


22


includes an open seam


162


that runs the entire axial length of cylindrical body


22


. This allows a user to place support system


20


on flashlight


24


on, or to remove support system


20


from flashlight


24


, both without the need to move flashlight


24


within a closed, solid, tight cylindrical body


22


.
