Abstract
A signalling device for roads or work sites. The device has a locked position and an unlocked position. In its locked position, when the device is prepared for use, its legs (15) project downwards while its notches (9) surround sections (8) of torsion bars (7, 8). These torsion bars are then raised up along with an indicator panel (1) which temporarily bends when the wind exceeds a certain strength. The device and the panel requires, no ballast and the panel is wind-resistant even on uniform road paving.
Claims19
A signalling device comprising:
- a rigid base frame (3);
- an indicator panel (1) having a lower part (2) pivotally mounted on a support assembly for pivotal movement about a transverse axis, said support assembly bearing on said base frame (3);
- said support assembly comprising two torsion bars (4, 5), each of said torsion bars including a central torsion segment (6) placed substantially horizontally relative to said rigid base frame (3) and said indicator panel (1), a first bent end portion (7) fast with said indicator panel 1);
- and
- a locking device for immobilizing said support assembly in a locked position at which said panel (1) is raised to a folded out position, substantially vertical relative to said rigid base frame and locking said panel relative to said base frame, and for unlocking said panel relative to said base frame, and for unlocking said panel relative to said base frame (3) when said panel (1) must be folded down into a folded down and unlocked position in the plane of said base frame (3);
- each of said torsion bars including a second bent end portion (8) for engagement with a locking notch (9, 21a, 24) in said locking device, when said indicator panel (1) is in said folded out position, and being releasable when said locking notch (9, 21a, 24) is moved to release said second bent end portion (8) and said indicator panel (1) is unlocked, for folding said panel (1) into said folded down position.
The device of claim 11, including a fixed longitudinal member (20) and a notch (24) in the upper face and in the outer vertical face thereof, said fixed longitudinal member (20) having a lower face pierced with a hole (25) aligned vertically with said notch (24), said second bent end portion (8) being folded onto itself in the form of a hook and comprising an end branch 98a) for vertical engagement through said locking notch (24) and said hole (25) in the locked position thereof and for housing freely inside said longitudinal member (20) in the unlocked position.
The device of claim 11, wherein each said locking notch (24) is formed in an upper face and in an outer vertical face of a fixed longitudinal member (20), the lower face of said fixed longitudinal member (20) being pierced with a hole (25) aligned vertically with said locking notch (24), and said second portion (8) is folded onto itself in the form of a hook and including an end branch (8a) for vertical engagement through said locking notch (24) and said hole (25) in said locked position and for being housed freely inside said longitudinal member (20) in said unlocked position.
