Definitions

• the present invention relates to a device, in particular for signaling of the self-rising type.
• signaling devices which consist of conical elements held in vertical position by a flat base.
• These devices which by their nature must be particularly light, have the drawback of being easily reversible, in particular under the effect of the wind, and then remain in the inverted position.
• the present invention aims to provide a device, used in particular in the field of signaling, which has the essential characteristic of getting up on its own.
• the present invention thus relates to a device, in particular for signaling, comprising a base, and a signaling element integral with the latter, this device being capable of occupying an unstable lying position and a stable raised position, characterized in that: - the axial cross section of the base forms four sides, namely a small base, capable of coming into contact with the ground when the device is in the raised position, a large base opposite to and parallel to the small base, two lateral sides symmetrical with respect to an axis perpendicular to the bases and which form a convex line seen from the outside,
• the shapes and dimensions of the base and the descriptive element are such that, when the device is lying on the ground, its center of gravity is located on the side of the small base with respect to a line perpendicular to the ground at the point contact of the base with it.
• the large base and / or the small base of the base is square, or rectangular. It can also be polygonal or circular.
• the base is made of a material of higher density than that of the sign.
• the upper part of the base can be hollowed out so as to form a bowl.
• the present invention is particularly advantageous in that, despite its lifting capacities, it is in the normal position of use, in a position as stable as those of the prior art.
• the present device is also advantageous in that, like the devices of the prior art, it is easily stackable, which facilitates its transport and storage.
• the device can be made up of two parts, namely a base which is permanently in contact with the ground and a sign, in particular consisting of a cone, which is capable of being fixed on the base, for example by force fitting.
• Figure 1 is an axial and vertical sectional view of a signaling device according to the invention in the inverted position.
• Figure 2 is an axial and vertical sectional view of the signaling device shown in Figure 1 during its recovery phase.
• Figure 3 is a partial view in axial and vertical section of the signaling device shown in Figures 1 and 2 in the stable position of use.
• FIG. 4 is a top view of the signaling device shown in FIGS. 1 to 3.
• Figure 5 is a partial axial and vertical sectional view of a signaling device according to the invention produced in two integral parts.
• FIGS. 1 to 4 essentially consists of a base 1 and of a descriptive element constituted in the example represented by a cone 3.
• the base 1 and the cone 3 are made of a single piece of synthetic material obtained by molding.
• the base 1 has the shape of a square whose corners are rounded. This base could of course in particular be of circular or rectangular shape.
• the signaling device has an axis of symmetry yy ', and if it is represented in section by a plane passing through this axis of symmetry yy', as shown in particular in Figures 1 and 2, we see that the cross section of the 'base 1 is made up of four sides, namely a small base la, a large base lb and two lateral sides le which are symmetrical with respect to the axis yy'.
• the small base 1a of the signaling device is arranged at the lower part of the base 1 so that, in the normal position of use, the device is supported thereon, as shown in FIG. 3 which gives it good stability.
• the ends of the large base 1b and the small base 1a are joined by the two other sides 1c which form a convex curve when viewed from the outside.
• the base 1 is hollowed out so as to form a bowl 4, which makes it possible to move its center of gravity G in the direction of the small base 1a.
• the dimensions of the descriptive element 3, and in particular its length, as well as the distribution of the weight of the base 1 are such that, when the signaling device is in the lying position, as shown in FIG.
• the center the gravity G of the assembly is located on the side of the small base by with respect to a straight line zz 'perpendicular to the ground at the point of contact 0 of the base 1 with it.
• the signaling device according to the invention is thus a rectifiable device which, after having been laid down under the effect of a shock, wind, etc., resumes itself a stable position.
• ballasting means at the lower part of the base 1, which can be constituted in particular by a metal washer 6 fixed by bonding therein, thus as shown in Figure 6, or by metal balls.
• the descriptive element which, in the examples described, consists of a cone 3, can be formed of any other element, depending on the use which one wishes to make of it.
• the signaling device can be made in two parts, which can be made of different materials, and in particular of materials of different densities. This will take a much denser material to make the base 1, which will have the effect of improving the righting torque C of the device.
• the lower part of 1 base 1 has a frustoconical orifice 7 of the same conicity as that of the sign 3, so that these two elements can be fixed for example by wedging, with addition or not of bonding means.
• An advantage of the signaling device according to the invention is that it is stackable, which is advantageous from the point of view of storage and transport.
