Collapsible luminous element for signalling a stationary vehicle, provided with a further intermittent signal light

Abstract: Collapsible luminous element for signalling a stationary vehicle, provided with a further intermittent signal light, small in size when in inoperative position and perfectly visible when in operative position, comprising a box-shaped flat base (1) having a semicircular part (2) provided with an upper opening, a square part (3) and a signalling hollow body (2A,2B,2C) shaped like a frustum of cone which is contained and supported by said base (1), in said semicircular part (2), being said hollow body in said retracted inoperative shape entirely contained in said box (1) while in said upright operative shape it projects vertically from base (2) in full height, characterized in that said body is composed of a series of rings (2A,2B,2C) similar in shape whose bottom and top diameters decrease from lower (2A) to upper element (2C), and having such a size that the bottom rim of the upper element (2C) can engage with the top rim of the lower element, characterized in that said frustumshaped rings (2A,2B,2C) are made of a translucent material, alternatively coloured in white and red, so that the body itself becomes competely luminous when lit from the inside.

Description: The subject-matter of the present application is a collapsible luminous element for signalling a stationary vehicle, provided with a further intermittent signal light. It is generally known how dangerous it can be a stationary vehicle on the side of the roadway and, all the more, on the roadway itself, especially when driving on expressways or after curves, cat's backs, humps and the like. With reference to this subject, the Highway Code prescribes the possession and usage of the well-known triangle of reflective material, which triangle, however, has not proved to be satisfactorily visible and, accordingly, effective, either by day or by night. The present application aims therefore to provide an element for signalling a stationary vehicle or, more generally, a danger on the roadway, which element, while taking the minimum room when stored in the boot of the car in inoperative position, is greatly visible, both by day and night, when in operation. In this field FRA- 2.211.025 (Document D1) and U.S. 5.155.667 (Document D2)are known but they describe a different luminous element. In D1 the collapsible luminous element springs from the box when a locking element is removed as the coil spring, completly contained in the compressed condition in the box, snaps to the extended position. D2 describes a luminous collapsible element comprising more elements nesting one inside the other and wherein the bottom rim of the upper element engages the top rim of the lower one but they are merely cilindrycal elements the diameter of which does not decrease from bottom to top as instead it is described and illustrated in the instant invention. The signalling element being subject-matter of the present application consists of a flat base shaped like a box comprising a semicircular and a square part, and a signalling hollow body shaped like a frustum of cone contained and supported by the semicircular part of said base, which hollow body, as it will be better seen afterwards, can assume a retracted inoperative shape wherein it can be entirely contained in the box and an upright operative shape wherein it projects vertically from the base in full height. The signalling body comprises a series of similar rings or sections having the base and top diameters which decrease from lower to upper element, and such a size that the bottom rim of superior element can engage with the top rim of inferior element. Besides, the fustum-shaped sections are made of a translucent material, alternatively coloured in white and red, intended therefore to become luminous when lit from the inside. On top of superior frustum-shaped ring, over a collar-lid, a circular seat is formed, closed by a cylindrical cap which is also made of a translucent material, wherein a lamp is lodged. The bottom box of opaque material contains a second lamp placed at the bottom of the signalling body and a supply battery, preferably of the rechargeable kind, intended to feed both bottom and top lamps by means of a switch. It will be useful to point out that the signalling element being subject-matter of the present application, which is similar in shape to the cones for signalling danger or a change of route presently used on roads and motorways, is not a component part of the car and is not intended to substitute the emergency triangle, rather it aims to increase safety and attention reducing the risks which an emergency stop due to whatever reason may involve, especially in case of heavy rain, by the light of dawn or dusk, or in case of mist or fog. The subject-matter of the present application will be now described in greater detail with reference to the attached drawings, wherein: fig.1 is a perspective view of the element in operative position; fig. 2 is an elevation view of the element in the same position; fig.3 is an axial section of the element as shown in fig.2; fig.4 is an elevation view of the element in inoperative position; fig.5 is an axial section of the elevation view shown in fig.4; fig. 6 is a view from above of the element in inoperative position. With reference to figures 1, 2 and 3, the signalling element, shown in its operative position, comprises a flat box 1 having a semicircular part 2 and a square part 3, and several frustum-shaped rings of a certain height, 2A, 2B and 2C, wherein the top rim of each ring has such a diameter as to accommodate the bottom rim of the upper ring, so that the two rims are engaged with each other, being the rings preferably made of a proper rigid plastic, translucent, alternatively coloured in red and white. The bottom of lower ring 2A engages with the top rim of semicircular part 2 of box 1, which semicircular part is also slightly shaped like a frustum of cone and is actually the bottom frustum-shaped ring, The inside of square part 3 of base 1 contains a battery 4 and is connected with the inside of semicircular part 2 of box or base ring 1. On top of upper frustum-shaped ring 2C a collar 5 has been fixed whose diameter is the same as the external diameter of the rim of the upper opening formed in part 2 of box 1, so as to function as a closing cover for the box when the element is in inoperative position (figures 4,5 and 6). Over collar 5 a seat 6 is formed intended to accomodate a lamp 7, with its relative lampholder, closed by a red (or orange) translucent cap 8, being lamp 7 fed by battery 4 by means of switch 9, placed on upper face 10 of box 1. As already mentioned, a second lamp 12, also fed by battery 4, is lodged in lampholder 13, placed in cylindrical part 2 of box 1 on the bottom of the conical body, so as to illuminate it from the inside when lit, so that the cone, because of the nature of the material which it is made of, becomes luminous and is perfectly visible in conditions of insufficient light. Lamp 12 is protected by a transparent cap 14. Finally, the box is provided with a retractable handle 14A (fig.4) so as to be carried more easily. The component parts above illustrated are obviously arranged in such a way that when the element is inoperative (figures 4-6) frustum-shaped rings 2A-2C accommodate the one within the other in part 2 of the box, with collar 5 closing the opening of the latter, cap 8 protruding over the collar. In order to bring the element to the operative position it will be sufficient to lift collar 5 up to the point that the bottom rim of each frustum-shaped ring gets engaged with the top rim of the lower frustum-shaped ring so as to reach the situation shown in figures 1-3. Thereafter, the element is placed on the roadway in the proper position and lamps 7 and 12 are lit so that the element will be perfectly visible at 360 degrees under any condition of light. Lamp 7 can be possibly fed by means of an intermittence device. In an alternative embodiment lamp 12 could be placed on top of frustum-shaped ring 2C, fixed to lower face of collar 5. Obviously, inverting the operations the cone will be brought again to the inoperative position, wherein it is not cumbersome, and will be then placed with no trouble in the boot of the vehicle equipped with said cone. The size of both the conical body and the box can vary according to one's need.
