Definitions
- the present invention relates to a signaling device both portable and anti-winding, comprising an indicator panel.
- a signaling device both portable and anti-winding, comprising an indicator panel.
- Such a device is intended to be placed on the ground and it can be used to carry an indicator panel of any type. In particular, it may be a road sign, industrial or commercial advertising, signage on a site, etc.
- the present invention aims to avoid these drawbacks, by providing a signaling device that is both light, foldable, and usable without ballast, when in fact it has perfect stability when placed on any ground, or even on the roadway of a highway, even if the panel it supports is large.
- this signaling device comprising a rigid base frame, surmounted by a foldable indicator panel in the plane of the base, is characterized in that the lower part of the panel is supported and pivotally mounted, around a horizontal and transverse axis, on the front of the base frame, by an elastic return support assembly by means of at least one torsion bar, and a locking device is provided for immobilizing the elastic return support assembly in the position where the panel ' is raised upwards, substantially vertically, or to unlock it, when the panel must be folded down in the plane of the base.
- FIG. 1 is a perspective view of a signaling device according to the invention , when in the deployed position.
- Figure 2 is a perspective view of the same device, in the folded position.
- Figure 3 is an elevational view, on a larger scale, of the elastic return mechanism with two torsion bars.
- Figure 4 is a perspective view, on a larger scale, showing a part of the locking device of one of the torsion bars.
- FIG. 5 is a partial elevation view in the direction of the arrow V in FIG. 1.
- Figure 6 is an elevational view in the direction of arrow VI of Figure 1, illustrating the elastic return mechanism in excess of neutral, provided for immobilizing the locking beams.
- Figure 7 schematically illustrates an alternative embodiment comprising a tubular beam with square section crossed by a zig ⁇ zag spring wire.
- Figures 8 and 9 are partial perspective views in the direction of arrow VIII of Figure 7, when the spring wire is respectively in one and the other of the two possible diagonal positions.
- Figures 10 and 11 are partial perspective views illustrating an alternative embodiment of the locking device of the bars torsion, respectively in the locked and unlocked position, used with the variant shown in Figures 7 to 9.
- Figure 12 is a partial perspective view of another alternative embodiment of the locking device.
- FIG. 13 is an elevation view of the locking device shown in FIG. 12.
- FIG. 14 is an elevation view of the torsion bars used with the locking device of FIGS. 12 and 13.
- Figure 15 is a plan view of a stackable base frame.
- FIG. 16 is an elevation view of the base frame of FIG. 15.
- FIGS 1 and 2 a signaling device according to the invention comprising an indicator panel 1 (shown in phantom), the lower part 2, substantially horizontal, is pivotally mounted, about a transverse axis, on the front of a horizontal frame 3 serving as a base.
- the articulation is ensured by two torsion bars 4 and 5.
- Each of these bars comprises a central torsion segment 6, substantially horizontal, materializing the axis of articulation of the panel, this central segment 6 extending between a first section extreme 7, bent and rigidly integral with the indicator panel 1, and a second end section 8, bent on the same side as the first end section 7 and capable of being engaged in a notch 9 of the locking device, when the latter is in the locked position, to maintain the panel 1 deployed vertically ( Figures 1,3 and 4).
- the two notches 9 receiving the. second bent end sections 8 are respectively formed in two longitudinal members 10 forming part of the base frame 3.
- Each longitudinal member 10 is articulated on front 11 and rear 12 crossmembers of the base frame 3, in order to be able to pivot about a longitudinal axis horizontal 13.
- the two central torsion segments 6 of the two torsion bars 4 and 5 are arranged side by side, preferably inside a rigid tube 14, integral with the front cross member 11 and which holds them one against the other. .
- each of the two longitudinal members 10 is eccentric relative to its pivot axis 13.
- the locking notch 9 can be brought into a first position in which it is open towards the top and receives the second corresponding section 8, then extending upwards, from one of the torsion bars 4,5, to immobilize in rotation the first sections 7, thus maintaining the panel 1 deployed, that is to say - say in a substantially vertical position ( Figures 1,4 and 5).
- the notch 9 can also be brought, after a pivoting of the associated side member 10 by 90 ° outwards, in a second position in which it extends horizontally and opens outwards so as to release the second section 8 (FIG. 2), which then allows the panel 1 and the first sections 7 to be folded down in the plane of the base frame 3.
- Each of the longitudinal members 10 carries, at each of its ends, a support foot on the ground which is retracted in the plane of the frame 3 when the assembly is in the folded position (or else projects vertically downwards ( Figures 1,4 and 5) thus being perpendicular to the base frame 3, when the assembly is in the deployed position.
- the feet 15 form four crampons which come to hang securely on the ground, without it even being necessary to increase the weight of the assembly by placing ballast weights on the base frame 3.
- an elastic return mechanism is provided with a kinematics beyond dead center.
- this mechanism comprises, at the rear, a return spring 16, substantially horizontal, each of the ends of which is anchored on a rear leg 15, at a point 17 which is located both at the outside the interval defined by the pivot axes 13 and above the horizontal plane defined by these two axes, when the feet 15 extend downward.
- this elastic return locking device has been replaced by two fixed tubular beams 20, with square cross section. Inside each of these tubes is arranged a metal spring wire 21, shaped according to a plan zig-zag profile.
- This zig-zag wire naturally corresponds to a space requirement in width 22 substantially equal to the dimension of the diagonals of the inner square of the spar 20.
- the naturally planar shape of the zig-zag wire 21 gives the latter two positions of possible equilibrium in the spar 20, namely one in each of the diagonal planes of this spar.
- This elastic thread 21 can be passed from one to the other of the diagonal planes by forcing it there by action on its outer ends 23, folded back so as to constitute the equivalent of the aforementioned feet 15.
- each foot 15 or 23 constitutes, in the deployed position, both a foot which hooks the assembly to the ground in the manner of a crampon (FIG. 1), and a handle which the user uses, to deploy or fold the panel.
- FIGs 10 and 11 a locking device which is provided in the case where the signaling device comprises fixed tubular beams 20 as shown in Figures 7 to 9.
- the second section 8 of each bar of torsion 4,5 is engaged, in the locking position, in a vertical notch 21, open upwards, formed in the internal face of a locking block 22 fixed to the internal face of the spar 20.
- the upper part of the notch 21 communicates with a horizontal recess 23 formed in the internal face of the locking block 22. Consequently, when the second section 8 is housed in the bottom or the lower part of the notch 21 (FIG. 10), it is immobilized in rotation, which ensures locking the corresponding torsion bar.
- To unlock this bar (FIG. 11), it is sufficient to lift it, so as to bring it to the level of the recess 23, after which the second section 8 is found to be released and the indicator panel can then be folded down in the plane of the base frame.
- each torsion bar 4.5 is folded in on itself towards the inside, forming a hook and ending in a short extreme branch 8a parallel to the second section 8.
- the frame base 3 comprises fixed tubular beams 20 with square cross section and the upper horizontal face and the external vertical face of each beam 20 are pierced with a common notch 24.
- the lower horizontal face of the beam 20 is pierced with a hole 25 vertically aligned with the part of the notch 24 formed in the upper horizontal face.
- transverse tube 14 which is crossed by the central segments 6 of the two torsion bars 4,5, is free and it can move between the lower position shown in solid lines and the upper position shown in dashes in figure 13.
- Figures 15 and 16 show a base frame 3 which can be used for the signaling device according to the invention.
- the two fixed side members 20 comprise a central part horizontal extended, at its two ends, by end portions 20a which constitute inclined legs, at 45 ° for example, downwards and outwards from the frame 3, so that the signaling devices can be stacked.
- the two longitudinal members 20 are connected by front 11 and rear 12 crossmembers, the crossmember 11 serving for attachment to an easel.
- the device according to the invention has many advantages.
- it is no longer necessary to use a ballast and when the wind is blowing, or else due to air movements resulting from automobile traffic, the traffic sign 1 more or less tilts, against the return action of the torsion bars 4 and 5, thereby reducing the thrust which tends to move the base 3 on the ground.
- the pivot axis 2, materialized by the torsion bars 4,5, is located at the lower part of the panel 1.
- the base 3, constituted by a closed frame, is particularly rigid and stable.
