DETAILED DESCRIPTION OF THE INVENTION
FIGS. 1-5 and 8 show a preferred embodiment of the apparatus of the present invention designed generally by the numeral 10. Walking cane 10 employs an elongated shaft 11 such as a cylindrically shaped shaft of translucent or transparent material such as a Lucite shaft. The cane 10 has an upper end portion 12 that can be provided with a cylindrically shaped opening or socket 13 that is receptive of a standard flashlight 17. The shaft 11 can be about 2.5-3.5 feet long as an example. The shaft 11 can be about 7⁄8 inches in diameter as an example. The lower end portion 14 of the cane 10 is fitted with a foot 15 which can be of a polymeric or rubber material. The foot 15 has an opening 16 through which light can shine when the flashlight 17 is illuminated.
Flashlight 17 can be generally cylindrically shaped. Flashlight 17 can be any commercially available flashlight such as any model flashlight manufactured and sold under the trademark “MAGLITE”®. Suitable flashlights 17 could for example include the MAGLITE® Excel 100 LED, Mini MAGLITE®, Mini MAGLITE® LED, MAGLITE Solitaire® as examples. Batteries, a light bulb, a switch and conducting wires can be housed within flashlight 17. Flashlight 17 can preferably be provided with an end cap 18 which would be removable from flashlight body 19 for inserting or removing batteries. Flashlight 17 provides an illuminated end portion 20 that provides an illuminating member, such as a bulb, LED, or the like. The flashlight 17 has the ability of generate a light beam along a path 36. In FIG. 3, the illuminated end portion 20 directs light along a path generally aligned with shaft 11, as indicated by line 36.
In FIG. 8, arrows 21 designate the direction of illumination of light from flashlight 17 when the switch of the flashlight is used to activate the flashlight 17 moved to an “on” position. Illumination of light from the flashlight 17 can for example be directed downwards. Illumination of light from the flashlight 17 can for example be directed multi-directional. It should be understood that the switch to illuminate the flashlight 17 could be by means such as rotating one part of the flashlight relative to the other, a button, a slide, or any other switch known in the art. Some flashlights, such as the Mini MAGLITE® are switched “on” or “off” by rotating one section 28 relative to another section 29 as indicated by arrow 30 in FIG. 3. Flashlight 17 can be held in place by a set-screw, set knob, frictional fit, threaded fit, cylindrically shaped rubber or polymeric bushing, adhesive, or other such connection. Set screw 25 threadably engages an internally threaded opening or socket 31 so that rotation of set screw 25 enables set screw 25 to selectively engage and grip or release flashlight 17 body 19, depending upon the direction of rotation of the set screw 25.
Handle 22 provides an upper surface or upper portion 23 that would be typically grasped by the palm of a user when manipulating the cane 10. Handle 22 provides an upper surface 23 and a socket or bore 24 that extends to the upper surface 23, communicating with opening 13. In this fashion, the flashlight 17 can extend into the opening 13 and bore 24. Flashlight 17 extends in part above upper surface 23 as shown in FIG. 3. In this fashion, a portion of the flashlight 17 body 19 extends above the surface 23 so that a user can twist the flashlight 17 to turn it on or off or access a button or slide or other switch on the flashlight body 17. The exposed part of the flashlight 17 seen in FIG. 3 would be used to move the flashlight switching device between illuminating and off positions. For the Mini MAGLITE® flashlight 17, a twisting motion would be applied to the upper section 29 of the body 19 that extends above the surface 23 in FIG. 3 in order to either activate or deactivate the bulb or LED and thus the illumination. Set screw 25 would clamp the lower section 28.
Handle 22 can be secured to shaft 11 at surface 35. Shaft 11 can extend into bore or socket 34 of handle 22 for example as seen in FIGS. 3 and 5. Handle 22 could be secured to shaft 11 by any suitable means such as for example a set screw, set knob, frictional fit, threaded fit, cylindrically shaped rubber or polymeric bushing, adhesive, or other such connection. The set screw 25 could be simply loosened in order to remove the flashlight 17 if the user wanted to obtain full access to the flashlight 17 such as for purposes of servicing it, or using it to find objects such as keys. Upper end portion of shaft 11 can include socket or bore 33. Bore 24 can extend in socket 33 of shaft 11. Flashlight 17 can extend into the opening 13 and bore 24 of handle 22 and socket 33 of shaft 11.
In FIGS. 6-7, an alternate embodiment is shown wherein the socket 24 is fitted with a cylindrically shaped (e.g., foam or rubber) bushing or sleeve so that a friction fit could be formed between the flashlight 17 and the sleeve 26.
In FIGS. 6-7, the bore 32 of sleeve 26 could be sized and shaped to closely fit the outside surface of the body 19 of flashlight 17. For example, bore 32 could be of a diameter or transverse cross section that is smaller than the diameter or transverse cross section of flashlight 17. The illuminated end 20 of the flashlight 17 could be of a larger diameter than bore 32 diameter so that the flashlight 17 could not be removed unless the frictional force holding the flashlight 17 to the sleeve 26 were overcome.
The flashlight 17 could thus form a frictional fit with the sleeve 26. In such a case, a user could remove the flashlight 17 by simply pulling it upwardly in the direction of arrow 27 in FIG. 7, overcoming the frictional fit between the flashlight 17 body 19 and the rubber or polymeric sleeve 26 that occupies the socket 13, 24. Such a sleeve 26 could be removable from the socket 13, 24 or could be permanently attached to the socket 13, 24 using an adhesive for example. The handle 22 could be of any suitable material such as wood, plastic or metal.
