FR2645887A1 - Device providing wind stability of any mobile sign panel or the like - Google Patents

Abstract

The invention relates to a device which can be fitted onto a mobile and foldable panel support, making it possible to stabilise this support against air movement. It consists of non-skid blocks 1 placed at the base of the support, a spring system 2 3 absorbing the energy applied onto the vertical part of the support 9. Following movement of air, the panel tilts on its axis of rotation 5, and returns to the initial vertical position under the return effect of the spring 2 when the air movement ceases. A damping spring 3 attenuates the return shock effect due to the spring 2. An automatic locking system 4 makes it possible to rigidly attach the articulated vertical part of the support 9 onto the base. The device according to the invention is in particular intended for stabilising mobile and foldable panel supports (road signalling, advertising signs and pre-informational publicity signs).

Description

DESCRiIPTION
The present invention relates to a device adaptable to a movable and foldable panel support to ensure the stability of this support to the movement of air.

 The type of support traditionally used in temporary road signs under the effect, on the one hand, of the breath of the wind and on the other hand, of the movement of air when heavy vehicles pass, moves, overturns, folds back, no longer ensuring the safety of staff and users.

 To remedy this situation, some users ballast the support implemented, using Ge loads of various sandbags, concrete blocks, etc.> which leads to an increased risk for the agents responsible for installing this ballast since thus obliging them to make an additional round trip crossing of the roadway under traffic. The device according to the invention overcomes these drawbacks.

It includes:
- non-slip pads, rubber or neoprene, fixed on the part of the support in contact with the road, eliminating by improving grip, the risk of displacement of said support.

 - return springs, absorbing the energy created by the movement of air when heavy vehicles pass; the vertical articulated part of the panel support then tilts and, thanks to the spring return function, returns to its original vertical position.

 - shock-absorbing springs, attenuating the return impact e-effect due to the return spring.

 - an automatic system for blocking the articulated vertical part of the support, on the horizontal part in contact with the ground, preventing untimely folding of the panel support when vehicles pass; the system is released by simply pressing a pedal.

 The accompanying drawings illustrate the invention.

FIG. 1 represents, in elevation, the device as a whole according to the invention,
- Figure 2 represents1 in plan, the device as a whole according to the indication.

FIG. 3 represents, in elevation, a variant of the damping device,
FIG. 4 shows, in plan, the detail of the slide system with damping springs of FIG. 1,
FIG. 5 represents, in plan, the detail of the locking system,
- Figure 6 shows, in plan, the detail of the variant of the damping system of Figure: 3.

 The device shown in Figure 1,2,4 and 5 comprises non-slip pads (1) fixed to the horizontal part of the support.

 Springs (2) connected simultaneously to the horizontal part, and to the mobile and articulated part of the support, allow, as a result of air movement, the horizontal movement of the slide (6 of the holding bar (7), and consequently the inclination of the vertical part of the support on the axis of rotation (5).

 Springs <3) fixed at the end of the slides (E3), play the role of shock absorbers at the moment ot under the e ++ and of recall of the springs (2), the mobile and articulated part of the support ( 9) returns to its original vertical position.

 A blocking (4) fixed to the base of the support, allows automatic rusting of the vertical part of the support on sabase.

 In the alternative embodiment, according to FIGS. 3 and 6, the damping system of FIGS. 1 and 4 is omitted to be replaced by a damping system (10) mounted in place of the initial holding bars (7); the damping system (10) can be replaced by a gas damping system.

 The device according to the invention is particularly intended for mobile supports of panels (signage, signs and advertising pre-signs)
