Description
TITLE OF THE INVENTION
FLEXIBLE LIGHT SHIELD AND DIFFUSER
FIELD OF THE INVENTION
The present invention relates to a flexible light shield and diffuser. More specifically, it relates to a flexible light shield and diffuser attachment adapted to be coupled to a portable light such as a flashlight.
BACKGROUND OF THE INVENTION
As known in the art, flashlight wand attachments are used as illumination, notification, alerting and identification devices in a variety of applications. These devices typically comprise a rigid and hollow elongated body member, which diffuses light emitted by the flashlight (or other handheld signalling device) they are mounted on. Typically, the wand attachment is fastened to the flashlight by means of threads, a latch or the like. One drawback of such rigid wand attachments is that, when mounted on the signalling device, the wand attachment is obstructive and the overall device is not compact and cannot be easily carried or stored in confined spaces (e.g. a pocket or purse).
Additionally, as such wands are relatively long, misuse, for example by a user falling on top of the wand, can lead to injury or eventual death, in particular when the wand is broken during such misuse.
Consequently, there exists a need for a shield/diffuser attachment, which, when mounted on a signalling device, allows for the latter to be easily carried and stored, but returns to its original shape when in use.
SUMMARY OF THE INVENTION
The present invention addresses the above and other drawbacks by providing a flexible shield/diffuser attachment for a portable light, the light comprising a

DETAILED DESCRIPTION OF THE ILLUSTRATIVE EMBODIMENTS
Referring now to Figure 1, a flexible light shield and diffuser attachment, generally referred to using the numeral 10, will be described. The shield/diffuser attachment 10 comprises an open-ended elongated hollow body 12 and a flange 14 at one end thereof. In a preferred embodiment, the flange 14 comprises evenly spaced recesses as in 16, which ease gripping of the shield/diffuser attachment 10, as will be described herein below.
Referring now to Figures 2a and 2b in addition to Figure 1, the shield/diffuser attachment 10 is mounted on a flashlight, signaling device or the like 18. The device 18 is illustratively comprised of a rugged housing 20 fabricated from a durable material, such as plastic. A series of light emitting diodes (LEDs) as in 22 are mounted on the front face 24 of the housing 20 and protected by a dome shaped lens cap 26. The cap 26 is illustratively fabricated from a transparent or translucent material such as clear or opaque plastic, or clear plastic with a diffusing pattern etched in a surface thereof. The housing 20 also illustratively includes a compartment 28, which houses a battery (not shown) for supplying power to the electronics (not shown) which power the LEDs 22 when the device 18 is activated. The device 18 also includes a switch mechanism such a multi-position bezel-like rotary switch 30 mounted around the lens cap 26. By rotating the switch 30 in a clockwise or counter-clockwise direction, one of a number of instruction sets can be selected for powering the LEDs 22. The switch 30 comprises recesses as in 32, which ease gripping of the switch 30 when the latter is being rotated.
DETAILED DESCRIPTION OF THE ILLUSTRATIVE EMBODIMENTS
Referring now to Figure 1, a flexible light shield and diffuser attachment, generally referred to using the numeral 10, will be described. The shield/diffuser attachment 10 comprises an open-ended elongated hollow body 12 and a flange 14 at one end thereof. In a preferred embodiment, the flange 14 comprises evenly spaced recesses as in 16, which ease gripping of the shield/diffuser attachment 10, as will be described herein below.
Referring now to Figures 2a and 2b in addition to Figure 1, the shield/diffuser attachment 10 is mounted on a flashlight, signaling device or the like 18. The device 18 is illustratively comprised of a rugged housing 20 fabricated from a durable material, such as plastic. A series of light emitting diodes (LEDs) as in 22 are mounted on the front face 24 of the housing 20 and protected by a dome shaped lens cap 26. The cap 26 is illustratively fabricated from a transparent or translucent material such as clear or opaque plastic, or clear plastic with a diffusing pattern etched in a surface thereof. The housing 20 also illustratively includes a compartment 28, which houses a battery (not shown) for supplying power to the electronics (not shown) which power the LEDs 22 when the device 18 is activated. The device 18 also includes a switch mechanism such a multi-position bezel-like rotary switch 30 mounted around the lens cap 26. By rotating the switch 30 in a clockwise or counter-clockwise direction, one of a number of instruction sets can be selected for powering the LEDs 22. The switch 30 comprises recesses as in 32, which ease gripping of the switch 30 when the latter is being rotated.
4 Still referring to Figures 2a, 2b and 2c in addition to Figure 1, the flange 14 of the shield/diffuser attachment 10 is shaped to snugly fit over the switch 30 in order to avoid impairing the use of the latter. In addition, when mounting the shield/diffuser attachment 10 to the device 18, the recesses 16 of the shield/diffuser attachment 10 are preferably fitted over the recesses 32 provided on the switch 30. As a result, the flange 14 can be easily gripped (by placing the operator's fingers into the recesses 16) and rotated, thereby rotating the switch 30 at the same time. Indeed, as will be apparent to a person of skill in the art, the rotary motion induced on the flange 14 is transmitted to the rotary switch 30. The signalling device 18 can therefore still be operated and an instruction set selected for powering the LEDs 22 with the shield/diffuser attachment 10 mounted thereon.
Referring now to Figures 3a, 3b and 3c in addition to Figures 1 through 2c, the body 12 of the shield/diffuser attachment 10 is preferably entirely fabricated from a flexible material, such as silicon or rubber or the like, which retains memory of its shape such that once collapsed the shield/diffuser 10 will return to its original shape. This will allow the shield/diffuser attachment 10 to be pliable and thus the overall device (or the shield/diffuser attachment 10 alone) can easily be stored in confined spaces such as pockets, purses and the like.
Such a design makes the overall device more compact and rugged, as it is not easily broken when stored or carried. The shield/diffuser attachment 10 design of the present invention has the additional advantage of alleviating the need for tools for mounting the shield/diffuser attachment 10 to the signalling device 18.
As a result, it will be apparent that the overall construction of the signalling device is cost effective.
Still referring to Figures 3a, 3b and 3c in addition to Figures 1 through 2c, in addition to being flexible, the body 12 of the shield/diffuser attachment 10 may be opaque (Figures 3a and 3c) or transparent or translucent (Figure 3b). For this purpose, clear or tinted rubber may for example be used. The body 12 may further vary in length, shape and size according to the desired signalling application. For example, the body 12 could have a truncated cone (Figure 3b) or a cylindrical shape (Figure 3c).
Still referring to Figures 3a, 3b and 3c in addition to Figures 1 through 2c, when

Still referring to Figures 3a, 3b and 3c in addition to Figures 1 through 2c, in addition to being flexible, the body 12 of the shield/diffuser attachment 10 may be opaque (Figures 3a and 3c) or transparent or translucent (Figure 3b). For this purpose, clear or tinted rubber may for example be used. The body 12 may further vary in length, shape and size according to the desired signalling application. For example, the body 12 could have a truncated cone (Figure 3b) or a cylindrical shape (Figure 3c).
Still referring to Figures 3a, 3b and 3c in addition to Figures 1 through 2c, when
5 the signalling device 18 is in operation, the light emitted by the LEDs 22 is directed by the shield/diffuser attachment 10, which is thereby more readily visible at great distances. Indeed, the upper end of the hollow body 12 preferably has an opening formed therein, which allows for a portion of the light emitted by the LEDs 22 to pass through the body 12 unobstructed. This design further eliminates the need for removing the shield/diffuser attachment 10 when such unobstructed light is desired. In addition, when the shield/diffuser attachment 10 is made of transparent or translucent material, the body 12 is illuminated when the signalling device 18 is in operation, thus increasing the visibility of the overall device.
Referring now to Figure 4, in an alternative illustrative embodiment of a shield/diffuser attachment 10 in accordance with the present invention the hollow body 12 can be translucent with a closed and tipped with a translucent dome 34. The dome 34 serves to disburse light which would otherwise exit the end of the hollow body 12 as well as improve suction such that when the flange 14 is mounted on the end of a flashlight or the like (not shown) the gripping for exerted by the flange 14 on the end of the flashlight is improved.
Referring now to Figure 5, in a second alternative illustrative embodiment of the present invention the flange 14 of the shield/diffuser attachment 10 includes an inner surface adapted to mate with a corresponding hollow collar 36. In operation, the barrel of the flashlight (not shown) is inserted into hollow collar 36 and a threaded inner surface 38 of the flange is illustratively threaded onto a corresponding threaded outer surface 40 of the hollow collar 36, thereby securing the shield/diffuser attachment 10 to the collar 36 over the end of the flashlight. The diameter of the aperture 42 of the collar 36 is suitably chosen to adapt to the diameter of the barrel of the flashlight. Typically, the collar 36 is
