DETAILED DESCRIPTION OF THE INVENTION

(8) The following detailed description is of the best currently contemplated mode of carrying out an exemplary embodiment 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.

(9) Broadly, an embodiment of the present invention provides an electromechanical safety warning light system using electromechanical actuation for automatically providing visual output from, for example, flashing red or red/yellow highly visible LED lights to warn a passing driver or bicyclist of an obstacle in its path. The electromechanical safety warning light system includes circuitry actuated by way of a magnetic-based switch to effectuate the light-emitting portions. The safety light may embody a unique structure, jointed in a plurality of waterproof sections and thus configured in size and flexibility to fit and adhere to the inner metal fitting face surface areas of and along an open car door. The fully integrated power source and the jointed structure allow the safety light embodied by the present invention to be placed anywhere on that inner metal surface, thus enabling applicability to different car manufacturers and models. In one embodiment, the present invention automatically turns on bright red and/or red/yellow blinking warning LED lights at the moment the car door opens, which are highly visible throughout the entire opening arc of the door, and do not shut off until the car door closes. As a result, there is no need for the exiting driver or passengers to remember to manually trigger switches or settings. Of course, they must be aware of passing traffic near to them, but they have the added protection of advanced cautionary notice to all those who are passing by. Further, this device can be placed on all car doors, thus providing this important protection on both sides of any car and on all four doors. Moreover, the present invention does not need a corresponding magnet to be separately attached and aligned along the opposing door well or jamb to work, thus significantly enhancing the ease of installation of the present invention. The power source of the safety warning light system is a replaceable battery or batteries and thus requires no connection to nor causes interference with the internal electrical or computer system of the vehicle.

(10) In addition, the fully integrated power source for the magnetic circuitry is a replaceable battery or batteries, not connected to the electrical system of the car, thus making the installment of this safety device extremely fast, easy and low cost and, perhaps most importantly, unable to interfere with the internal electrical or computer system of the vehicle. Furthermore, even if the battery of the vehicle is dead, the present invention will continue to provide light and thus protection.

(11) Referring now to FIGS. 1A through 4, the present invention may include a length, width and depth of approximately two to ten inches long, by one-half to two inches wide, by one-quarter to three-quarter inches deep in order to be universally adaptable to fit in the inner metal car door site or fitting face of most car doors on the market today. However, the dimensions may be otherwise dimensioned and adapted and are not to be considered limiting. In one exemplary embodiment, the present invention may provide a plurality of jointed, waterproof sections. The safety light device may be molded from a plasticized material which rests on flexible backing material 1 allowing it to mold and adhere to the variable and small contours of the inner metal fitting face of the car door. In this exemplary embodiment, the light output 2 is designed to emit bright, flashing LED lights widely through the front and beveled sides of the red and yellow colored lenses so that the lights may be visible throughout the entire arc of the opening door and remain on until the car door is closed. The red and yellow lenses (light output 2) may be fitted into their plastic housings covering LED output devices (seen in FIG. 1B as 5). The middle section of the warning light device, the housing 3, houses the magnetic-based switch, replaceable batteries and some of the circuitry. The flexible backing material 1 between the output 2 and housing portions 3 may act as living hinges or joints, providing flexibility and the capability for the entire length to bend at several portions enabling the present invention to conform and fit into variable contoured and small areas. The backing material 1 may be covered with an adhesive backing material 4 which will be designed to strongly adhere to the metal surface of the inner door sites, be removable without damaging the painted surface of the inner car door sites and be able to withstand a soaking rain. In certain embodiments, the adhesive backing material 4 may be magnetic material adapted to removably adhere to the ferromagnetic surface.

(12) FIG. 1B depicts an exploded view of a fully-assembled example of an embodiment of the jointed safety warning light device. In this exploded view, the LED lamps or bulbs 5 are centered under each of the four light lenses which in this preferred embodiment example are two red and two yellow. The LED platforms 6 which house the LED bulbs 5 is the other side of the circuitry board 7 which controls the power of the light source, speed of blinking intervals and sequential order of blinking colors. In addition, the configurations of these variables are designed to be highly visible to passing traffic without being distracting, interfering or uncomfortably bright. All configurations of these variables are within the scope and spirit of the present invention, are contemplated thereby, and are intended to be covered by the claims herein. The magnetic switch and battery assembly 8, in an exemplary embodiment is contained within the center housing 3 and is depicted and described in detail in FIGS. 2A, 2B, and 4.

(13) FIG. 2A depicts the assembled magnetic switch and battery assembly 8 and the exploded view in FIG. 2B contained within the center housing 3. The power source 10, may be a battery or batteries, and may rest on the base plate 9. The circuit bracket 11 which may be copper or can be made of any other conductive material, runs from the battery 10, which it holds in place, to the switch beam 13. The connection point 12 on the end of the circuit bracket 11 connects the electrical circuitry and the switch beam 13. The contact point 14 connects the power circuit to the LED bulbs 5. The contact point 15 may be from the switched power circuit. The magnet 16 is fastened to the switch beam 13 at the attachment point 17 which rests on contact point 18. The switch beam's pivot point 20 rests on the pivot point base 19. Conductive piece 21 may be from the non-switched circuit. As depicted in FIG. 4, when the car door is closed, the magnet 16 is drawn up, attracted to the ferrous or ferromagnetic material of the inner metal face of the car door jamb. The circuit is open and the warning LED lights are off. The housing 3 in FIG. 1 prevents the magnet from over-extending. As soon as the car door opens and the magnetic switch and battery assembly 8 is not near the ferrous material of the inner metal face of the car door jamb, the magnet 16 attached to the biased springy switch beam 13 drops onto its contact point 18, closing the circuit and turning on the flashing red/yellow LED Bulbs 5, as illustrated in FIG. 4.

(14) The internal magnetically activated switch of this systemic device allows the instant safety system to be easily and quickly retro-fitted to pre-existing vehicles at low cost as opposed to expecting a consumer wanting this safety feature to have to pay for the systemic devices to be electrically coupled at considerable cost to the electrical system and/or computer system of the vehicle they wish to modify. This safety device is, therefore, one-piece, low-cost, and easily placed on the inner metal surface face of all car doors requiring, most importantly, no alignment of a separate systemic component, for example an external magnet, that must be attached, glued or riveted and align perfectly on the adjacent door jamb or well.

(15) FIG. 3 depicts an exemplary placement of the present invention on the inner metal door face of the open car door, illustrating one of many placements thereof. FIG. 3 is a close up of the exemplary placement of the jointed safety light device. The exact placement is expected to be somewhat variable depending on the make, model and configuration of the specific automobile. The device can be installed on all four doors if so desired. Other size configurations that adapt to the sliding doors of Minivans are contemplated within the scope and spirit of the present invention.

(16) 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 present invention as set forth in the following claims. Such modifications are not limited to, but may include among other things, changes to the circuitry, lighting elements and their location, color of the lens covers, size of and materials used for the jointed device or a singular non-jointed embodiment, selection of adhesives, magnets, batteries, and, as such, may be made without departing from the spirit and scope of the present invention.
