SUNSHADE OR THE LIKE Anne-Marie Golaz, ne Petrotf, Le Barroux, Grard Anatole Frangois Marie Joseph 3 Rue de la Marne, Ville dAvray, France Filed Sept. 30, 1963, Ser. No. 312,746 Claims priority, application France, Oct. 1, 1962, 910,863, Patent 1,354,814 6 Claims. (Cl. 2406.42)
One of the objects of the invention is to produce a protective device, such as an umbrella, which accords suitable lighting so as to facilitate the users movements and to announce his presence, for instance, to motorists.
Another object of the invention is to provide a lighting source incorporated in the protective device, this source being so arranged as to illuminate the fabric of this protective device such as an umbrella, so as to obtain, by diffusion, the lighting up of an area surrounding the user and that the beams difiused by the fabric announce the presence of the user, more particularly to motorists.
Another object of the invention is to place the lighting device inside the handle of the protective device so that the light beam emerges from the lower end of the handle so as to obtain suitable lighting, whether the handle be straight or curved.
Other objects and advantages of the invention will be revealed by the description and claims hereafter and the attached drawings, in which:
FIGURE 1 shows the device placed at the end of an umbrella or the like with a straight handle,

FIGURE 2 shows the device according to the invention placed at the end of a curved handle,
FIGURE 3 shows the light beam lighting up the fabric of an umbrella.
FIGURES 4 and 5 show other methods of embodiment of the lighting device incorporated in the end of a curved handle.
FIGURE 6 shows another form of embodiment of the lighting device,
FIGURE 6a shows the reflecting surfaces utilized in the lighting device of FIGURE 6,
FIGURES 7 and 7a show another form of embodiment of the device according to the invention.
The present invention relates to an umbrella provided with an independent battery or accumulator light source enabling direct or indirect lighting for multiple purposes. It also relates, by extension, to parasol-s and sunshades or other light protective articles, dismountable and transportable, for instance.
The utilizing of an umbrella by night, during rainy Weather, is very often accompanied by walking along sodden roads, covered with puddles that can hardly be seen, and it would be highly appreciated if it were possible to be surrounded by a lighted area enabling one to see where you are stepping. Furthermore, the visibility of automobile drivers being greatly limited during wet weather, it is most desirable to increase the safety of the pedestrian by making his presence luminous, without dazzling, however.
For these two reasons, the pedestrian might think of providing himself with an electric torch, but very often his hands are not free suitably to hold an additional object, and the main object of the invention is to incorporate a light source of this kind in the umbrella. Moreover, an ordinary flash light cannot simultaneously throw a beam to the right and left, front and rear. And, in a direction where it is visible, when seen from afar it only appears like a dazzling luminous point, whose distance away cannot be judged.
Patented Sept. 27, 1966 battery or rechargeable accumulator 3 with a spring contact such as 4. An end part 5 made, for example, in the shape of an internally threaded ring and framing a lens '6 will enable the luminous field to be limited to an area considered suitable. Screwing in more or less tightly 5 can eventually enable this field to be regulated by altering the distance of the lens 6 from the bulb 1. The switch is not shown, any type of switch being able to be combined with the present invention. In this first form of embodiment, the umbrella used normally will light up the ground, but also part of the pedestrians clothing which is also made visible.
In a second form of embodiment (FIGURE 2), the umbrella comprises a dismountable curved handle 7 eventually containing a conducting wire 8 connecting the electric source 3 to the bulb 1. The bulb 1 combined with the mirror 2 and the lens 6 lights the interior of the stretched fabric of the umbrella upwards (FIGURE 3). The latter can be more or less lit up (zone AB), but preferably, the light beam will be concentrated in such manner that it will not be uselessly wasted outside of the screen made by the stretched fabric. The latter can be more or less reflecting, but preferably, it should be selected light and semi-transparent, so that one part of the beam descends towards the ground in a field CD, whereas the other part is diffused by transparency, making the umbrella luminous from all sides, even when sloping owing to the slant of the rain. 7
In a third form of embodiment (FIGURE 4), an alternative of the second, the bulb 1 is placed in the immediate vicinity of the electric source 3 as in FIGURE 1, but the dismountable end of the handle 9 either curved or of polygonal shape, will be hollow and reflecting inside, except in the transparent end part and eventuallymade by a lens 6.
In a fourth form of embodiment (FIGURE 5), the dismountable end of the handle 3 is filled with a cluster of glass or plastic fibers conducting the light to the. transparent end part. i
In a fifth form of embodiment (FIGURE 6), a hollow handle 9 reflecting inside channels the light upwards towards a reflecting cone 12 installed opposite windows 11. The latter can be actually cut out, or be the transparent parts of the tube 9 not made reflecting. The angle of the cone should be chosen so as suitably to direct the beam reflected annularly towards the fabric of the umbrella. FIGURE 3 shows two regions E and F more or less high on the handle stafl', where the annular optical device of FIG. 6 could be mounted. The light beam could be rising, .if the light source is in the handle, or descending if the component 12 is placed with the battery in the upper end point of the umbrella staff above the shade, outside of the fabric, for example, and dismountable. FIGURE 6a also diagrams 'an arrangement of the 'bulb enclosed between two annular mirrors 17 and 17 device 2 can thus be made up of several diflerent curvature and orientation zones, spherical or otherwise. Thus in FIGURE 7a the reflecting surface 2 consists of three reflecting portions 2 and 2 .and 2 the portion 2 embracing the lower part of the bulb '1 Whereas the middle portion 2 will be more particularly intended to receive the .beamisent. by the cone 16 (projecting or hollow) whose rounded edge will concentrate on this zone 2 an annular image of the source. Its orientation willbe such that the beam coming directly from the source, and
the beamreflected will both be introduced into the an-' nular zone 13 with a suitable slope. V Lastly, the zone 2 is intended to send the lateral beam 1 of the bulb 1 directly into the annular zone. The six preceding forms of embodiment are only given by way of examples of embodiments, and by no means limit the generality of the invention which could, for instance, comprise several bulbs, and on the fabric, various reflecting or diffusing zones enabling various aesthetic or other decorations to be added to the essential object of the invention. Also, a lateral window can be provided in the stick or handle, close to the bulb, for instance, so that part of the beam may be .used to light up sundry objects close at hand, such as purse, note-book, etc.
