DETAILED DESCRIPTION

As discussed above, embodiments of the present disclosure relate to a mobility assistance device and more particularly to a walking aid system as used to improve a walking aid that is capable of emitting ambient light for increased safety or aesthetic purposes.
Generally speaking, the walking aid system may include a cane or walking stick that is made in part from clear materials along with a light source attached to it that makes the walking stick light up in a variety of colors. This not only makes the walking aid safer to use as dark roadways or rooms can be more easily traversed as a result of the ambient light being emitted from the cane, but it also provides an aesthetic alternative to traditional walking aids.
The walking aid system may be particularly useful in areas and at events where a flashlight beam to provide light for walking would be disruptive. During the day, the walking aid system can be used strictly as a cane, while at night it can be used both as a cane and as an implement that can assist with safer walking by illuminating the walking path. For example, a person may be attending an outdoor even that does not have full light coverage of walkways and to the parking area, so the user may activate the light feature to better see the walkways and other darkened paths. One alternative configuration could include a modified end piece that features an ice pick, to enhance or replace the shaft boot for increased traction in icy conditions. Other alternative configurations may feature a plurality of shaft diameters and/or materials to accommodate users of different dimensions, ages, and capabilities.
The walking aid system may have an elongated support shaft that may be at least partially made of translucent material that may be configured as a walking support having an upper end, a lower end, a length, and a height. The length may lie between the upper end and the lower end and the height is derived from the length. The height is generally understood to be measured from a floor to the location of the user's hand (e.g. the grip or the upper end). The elongated support shaft may also be adjustable in length providing a minimum and maximum height.
The walking aid system may include a handle assembly including a grip made possibly from elastomeric materials, which may be fixed to the upper end of the elongated support shaft in a manner that makes it easy for a user to retain hold of the handle assembly. In addition, the handle assembly may be configured to be capable of supporting at least 100-200 lbs. of force applied to the handle.
The handle assembly may further include an open-end receiver and a retainer, which may be configured to be removably-secured around the wrist of a user. At the lower end of the elongated support shaft, the device may have a frictionally secured shaft boot that may be made at least partially from non-slip materials and may be configured for direct contact with the walking surface (e.g., the floor) while in use.
In addition, the elongated support shaft may have a selectable light source that may be configured to emit an ambient light emanating from the elongated support shaft. This light source may have a user interface configured to selectably operate the light source and may also feature a color selector that allows a user to choose from, for example, between one and ten selectable illumination configurations. After a selection is made, the elongated support shaft may be designed to optically channel the selected color of light from the light source down the length of the elongated shaft towards the shaft boot in a manner that may produce an ambient lighting effect around the shaft. The light source itself may be at least partially retained inside the open-end receiver of the handle assembly and may be powered by an energy storage that may include a DC power supply. The DC power supply may be removably electrically-coupleable to the light source, and may further include one or more rechargeable batteries.
Referring now more specifically to the drawings by numerals of reference there is shown in FIGS. 1-4, various views of a walking aid system 100. In a preferred embodiment the walking aid system 100 includes an elongated support shaft made of translucent material configured as a walking support having an upper end, a lower end, and a length, where the length may lie between the upper end and the lower end. The elongated support shaft may also be adjustable in length between a minimum and maximum height.
The walking aid system may also have a handle assembly including a grip made possibly from elastomeric materials that may be fixed to the upper end of the elongated support shaft in a manner that makes it easy for a user to retain hold of the handle assembly. The handle assembly may be capable of supporting at least 200 lbs. of force. The handle assembly may further include an open-end receiver and a retainer that may be configured to be removably-secured around the wrist of a user. At the lower end of the elongated support shaft the device may have a shaft boot made at least partially from non-slip materials and configured for direct contact with the walking surface while in use.
In addition, the elongated support shaft may have a selectable light source that may be configured to emit ambient light from its surface. This light source may have a user interface that regulates its operation and may also feature a color selector that allows a user to choose from up to at least 10 different predetermined colors. After a selection is made, the light source may be designed to optically channel the selected color of light from the light source down the length of the elongated shaft towards the shaft boot in a manner that may produce an ambient lighting effect. The light source itself may be retained inside the open-end receiver of the handle assembly and may be powered by an energy storage that may include a DC power supply having at least one rechargeable battery. The walking aid system may further include a set of user instructions, with the entire system being arranged as a kit.
