DETAILED DESCRIPTION

[0026] The following detailed description is of the best currently contemplated modes of carrying out exemplary embodiments of the invention. The description is not to be taken in a limiting sense, but is made merely for the purpose of illustrating the general principles of the invention, since the scope of the invention is best defined by the appended claims.

[0027] Broadly, embodiments of the present invention provides an illuminated handle bar grip. The illuminated handle grips may be utilized on any motorized or occupant propelled vehicle with a grip handle steering or control, such as a motorcycle, bicycle, four wheel all terrain vehicle (ATV), and the like.

[0028] As seen in reference to the drawings of FIGS. 1-7, the illuminated handle grips 10 according to aspects of the invention includes a grip body 12 having an outer surface covering that is positioned over an illumination diffuser element 14. The illumination diffuser element 14 is be adapted to be positioned over an end of a handle bar, or a control handle 16 (partially shown for clarity of the drawings), and may have an internal sleeve 14 that is configured for the same. The illuminated handle grips 10 may be applied to the handle bar control 16 of the selected vehicle. The grip body 12 has outer surface covering may be formed of a soft resilient material, such as rubber, neoprene, or the like. The grip body 12 may be generally cylindrical and may have protrusions disposed along a longitudinal length to accommodate a user's fingers and hands for gripping.

[0029] The outer surface of the grip body 12 has a plurality of cut outs 18 that may extend therethrough to expose at least a portion of the illumination diffuser element 14. A light source, such as one or more light emitting diodes (LEDs), electro luminescent (EL) materials, or the like may be in communication with the illumination diffuser element 14 such that light emitted by the light source is communicated through the illumination diffuser element 14 to be emitted through the one or more cut outs 18 in the outer sleeve of the grip body 12. When a transparent or a translucent material is used for the grip body 12, the one or more cut outs 18 may be recesses that where a thinning of the grip body 12 in the recess transmits more light from the light source than the remainder of the grip body 12. The internal sleeve, when present, or handle bar control surface 16 may be provided with a reflective surface so as to reflect light into the illumination diffuser 24 to improve light transmission.

[0030] In a non-limiting example, such as shown in reference to FIGS. 4 and 5, the light source may be configured as a light ring 20 with the LED emissions oriented through an emitting face 22 of the ring. The emitting face 22 may be positioned in abutment with an end of the illumination diffuser element 14. In some embodiments, the light source may include a light ring 20 applied in abutment with one or more of an outer and an inner end of the illumination diffuser element 14. As will be appreciated from the present disclosure, the illumination diffuser element 14 may be formed of an optically conductive material, such as Plexiglas or an Acrylic material. The illumination diffuser element 14 may have a transparent or a frosted surface treatment depending on a desired lighting effect emitted from the one or more cut outs 18 of the illuminated handle grip 10.

[0031] In an alternative non-limiting embodiment shown in reference to FIGS. 5-7, the illumination source may be an LED lighting strip 24 that may be carried within one or more interior chambers 26 defined along a longitudinal length of the grip body 12 of the hand grip 10. The LED light strip 24 may include an integrated diffuser element which carries the light emissions from a plurality of LED lights in the LED light strip 24 to the plurality of cutouts in the outer surface of the hand grip.

[0032] The light source is electrically connected to a power source, which may be a battery or an alternator or generator carried by the vehicle. In some embodiments, an end cap 25 for the illuminated handle grip 10 may be utilized to house a battery and battery connection. The battery may be carried within the end cap 25, or an end of the battery may be attached to the end cap 25, with a remaining portion of the battery dimensioned to be received within a void in the handle control 16 to which the illuminated handle grip 10 is attached.

[0033] The illumination source may be controlled in conjunction with other lighting systems on the vehicle via electrical conductors. Alternatively, the light source may be controlled independently of other lighting systems, for example by rotation of the end cap 25 or activation of a switch carried in the illuminated handle grip 10. The control may allow for variation of the lighting intensity and it may be configured to select between a steady or a flashing mode. As will be appreciated, the color of the light source may be varied, depending upon the application, or an operational condition of the vehicle, such as to indicate a turn or a stop.

[0034] As stated above, the illuminated hand grips 10 of the present invention illuminate for safety and visual enhancement so that other motor vehicle operators can better see riders better when the illuminated handgrips 10 are illuminated.

[0035] It should be understood, of course, that the foregoing relates to exemplary embodiments of the invention and that modifications may be made without departing from the spirit and scope of the invention as set forth in the following claims.
