With reference now to the drawings, and in particular to FIG. 1 thereof, a new and improved wheelchair monitoring system embodying the principles and concepts of the present invention and generally designated by the reference numeral 10 will be described.

The present invention, the new and improved wheelchair monitoring system, is comprised of a plurality of components. Such components in their broadest context include a magnet sensor, sensor couple, magnet couple, display, primary switch, and information mechanism. Such components are individually configured and correlated with respect to each other so as to attain the desired objective.

More specifically, it will be noted that the system 10 of the present invention includes a standard wheelchair control mechanism 12 situated at a rear extent of a conventional wheelchair and connected to a standard battery supply. The wheelchair control mechanism is adapted to allow controlled movement of the wheelchair with an associated joy stick 14 which is connected thereto.

Also included is a magnet sensor 16 with a cylindrical configuration. The magnet sensor is adapted to actuate upon the placement of a magnet adjacent thereto.

For holding the magnet sensor in its operative orientation, as shown in FIG. 1, a sensor couple 18 with a generally rectangular configuration is included. In its preferred operative orientation, the sensor couple has a front surface 20, a rear surface 22, a top face 24, a bottom face 26, and a pair of side edges 28. The sensor couple comprises a first semicircular axial bore 30 vertically formed on the rear surface thereof. A second semicircular axial bore 32 is horizontally formed on a lower extent of the rear surface whereby the semicircular bores form an intersection with an aperture 34 situated at an apex thereof. The aperture allows the insertion of a coupling screw 36 with a sharp tip therethrough. The sensor couple further includes a first full axial bore 38 horizontally formed therein at an upper extent thereof and extended between the side edges. Intersecting the first full bore is a second full axial bore 40 horizontally formed in the housing and extended between the front surface and rear surface. An aperture 42 is situated at the intersection of the full bores and allows the insertion of a coupling screw 44 with a blunt tip therein from the top face. Ideally, the sensor couple is constructed of a light weight alloy including aluminum. The sensor couple is adapted to allow the securement thereof to any one of a plurality of wheelchairs. In an operative orientation, as shown in FIG. 1, one of the semicircular bores is attached to a frame of the wheelchair adjacent to a side extent thereof and the magnet sensor is insertably coupled within one of the full bores so that it faces outwardly from the side extent of the wheelchair frame in a horizontal direction. Optionally, the rear surface may be lined with an adhesive to afford additional securement to the wheelchair.

A magnet couple 46 having a generally rectangular configuration is also included. In a preferred operative orientation, as shown in FIG. 1, the magnetic couple has a front surface 48, a rear surface 50, a top face 52, a bottom face 54, and a pair of side edges 56. The magnet couple includes a magnet 58 attached to a first side edge thereof, a groove 60 formed on a second side edge for receiving a conventional spoke 62 of a conventional wheelchair wheel, and an aperture 64 formed between the front surface and the groove. The aperture is adapted to allow the insertion of a coupling screw 65 with a blunt tip for allowing the securement of the magnet in a position whereby it passes adjacent to the magnet sensor upon the revolution of the wheel thus allowing the activation thereof. The magnet may be situated at any radial distance from the axle of the wheelchair as long as the magnet sensor is situated at a similar radial distance.

A display 66 is connected to the standard control mechanism for depicting a plurality of numerals. A primary switch button 68 is also connected to the standard control mechanism and is adapted to actuate upon the depression thereof. So that button may be e switch button may be easily viewed and operated by a user, they are positioned adjacent to the joy stick and integrally manufactured therewith in a specially designed interface housing 70. The interface housing may be removably coupled to an arm rest of the wheelchair so as to prevent the theft thereof.

Finally, an information mechanism 72 is connected to the control mechanism and magnet sensor. To facilitate the connection with the control mechanism, a plurality of contact strips 74 depend from a lower surface of the information mechanism and are adapted to insert within a plurality of contact apertures 76 situated on an upper surface of the control mechanism. Coupling screws 77 may also be included to afford additional securement. The information mechanism is adapted to calculate a total distance of travel and a speed of the wheelchair by monitoring the number and rate of actuation of the magnet sensor, respectively. The information mechanism is further adapted to depict on the display the distance upon a first depression of the primary switch button and further depict the speed upon a subsequent depression thereof. Additional functions are also afforded by the information mechanism by subsequently depressing the primary push button switch. Such functions include a standard stop watch function, a standard clock function, and a resetable trip meter function. The information mechanism is further connected to a plurality of secondary push button switches 78 to facilitate the use of the additional functions. For example, when utilizing the trip meter function, a secondary push button switch may be depressed in order to reset an odometer reading depicted on the display. It should be noted that the information mechanism comprises commonly known circuitry in order to accomplish the tasks thereof. Optionally, the information mechanism may also be adapted to monitor a heart of a user or afford a conventional calculator or computer.

Additionally, the information mechanism may comprise a small battery and an associated switch 80 for supplying power to the information mechanism upon the removal of the standard battery supply. When the standard battery supply is removed to be replaced with a new one, the switch may be actuated to prevent loss of information such as the total odometer and clock reading.

The present invention offers a unique method of affording a plurality of features to a user of a wheelchair. Such features include a resetable trip meter which is purposefully included so as to allow a user to judge the amount of power remaining in the standard battery supply. Also, the stop watch and speedometer provide a means of tracking exercise activity. The wheelchair monitoring system may also be integrally manufactured with the wheelchair using methods similar to those disclosed hereinabove.

As to the manner of usage and operation of the present invention, the same should be apparent from the above description. Accordingly, no further discussion relating to the manner of usage and operation will be provided.

With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of the invention, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the present invention.
