FR2930788A1 - Route or information signaling device for e.g. pathway, has cylindrical base whose centre of gravity is situated inside half-part of cylinder, which makes to and fro movement and comes back to same position - Google Patents

Abstract

The device has a cylindrical base (1a) whose centre of gravity is situated inside a half-part of a cylinder (2b), which makes to and fro movement and comes back to same position in order to let the lower part in direction of terrestrial centre of gravity. Two bars (4, 5) project outside a slit (3) to form a triangle with the base, so as to be liberated when the device is installed on the road using push buttons (7a, 7b).

Description

The present invention relates to a device for road signs, more particularly for pre-signaling triangles. When a vehicle is immobilized on the roadway, it represents a danger to traffic if it has not been signaled during bends, at road intersections, at underground passages, tunnels, emergency stop strips and in all circumstances when visibility is poor. Such a warning triangle or pre-signaling must be placed at least 30 meters away from the immobilized vehicle in order to be visible at a hundred meters from any user 10 occurring behind, on the same track. Unfortunately the ordinary pre-signaling triangles are dangerous because it is necessary to move and open it to be able to install it. There is therefore a risk of a bodily injury because the user of a vehicle coming from behind is surprised. In addition such a panel once spilled can no longer return to its original position. The device according to the invention makes it possible to remedy these problems. Figure 1 shows a simplified model of such a device. The device according to the invention consists of several parts, one of which is a half-tube base (la) whose center of gravity (2b) is located inside the half-tube.

Such a device has the ability to switch back and forth or to turn while returning to the same position that leaves the lower part towards the Earth's center of gravity. In addition two bars (4 and 5) or rods housed in the half tube may protrude from a projection or slot (3) to form a triangle (6) with the base (la).

Such a device according to the invention can be realized in different ways, one of the embodiments consists of blocking the two rods (4 and 5), inside the slot (3) with the possibility of being released at desired time by unblocking a bolt, a cleat or magnetic parts. FIG. 1 shows a simplified model of such a device: the device according to the invention consists of several parts, one of which is a cylindrical base (la) whose center of gravity is located inside a half part of the cylinder (2b). Such a cylinder has the ability to switch back and forth or to turn while returning to the same position that leaves the lower part (2b) towards the Earth's center of gravity.

Another way of making such a device is to put pushers (7a and 7b) which make spring the two branches (4 and 5) which rest under the effect of their weight in the projection (3). Both branches include signage. Figures 2 and 3 show such a device. The two bars (4 and 5) or rods accommodating in the half-tube (2b) can protrude from a protrusion or slot (3) to form a triangle (6) with the base (la) with the possibility of being released. when the device is placed on the road by the simple fact that the two branches (4 and 5) are deployed by pushers. The realization of such a device can be in the form of a cylinder (Figure 6) provided that one half of the cylinder is heavier than the other or the center of 45 gravity is inside the half cylinder and allows the tilting of the signaling device. It can also be in the form of a sphere or a half sphere (Figure 4 and 5) provided that one half of the sphere is heavier than the other or that the center of gravity is at inside the half sphere and allows the tilting of the signaling device. In this case it would be judicious to fix two cross-traffic signs.

Claims (4)

CLAIMS1- Device for road signs or information, especially for pre-signaling triangles characterized in that it consists of several parts, one of which is a half-tube base (la) or portion of tube, half cylinder or half sphere whose center of gravity (2b) is located inside this half-cylinder or half-sphere tube portion. 2- Device according to claim 1 characterized in that the center of gravity of the half-tube or half cylinder or half-sphere allows tilting back and forth of this sign or information panel. 3- Device according to claims 1 to 2 characterized in that the base comprises means for lifting elements fixing the signaling, with the possibility of being released when the device is placed on the road by the simple fact that the two branches (4 and 5) are deployed by pushers. 4- Device according to claims 1 to 4 characterized in that it can fix an existing signal triangle by simply blocking it inside a slot.
