Definitions
- the invention relates to an extendable barrier on casters produced by assembling pivoting modular elements which can be deployed and folded manually.
- a barrier in stretchable diamonds is already known on a guide cable for road, urban or pedestrian paths described in document FR 2 688 244.
- This barrier has the following drawbacks: it is made of anti-corrosion treated steel, therefore it is very heavy to handle. It is ma ⁇ oeuvrée on a guide cable stretched between two fixed points, by at least one cable on which it is immobilized; this cable is towed by a mechanical system with manual, semi-automatic or automatic winch. There is no detailed mechanism for deploying it, but only for folding it back, except in FIG. 5 showing a cable system not described, with a return loop in a guide rail for fixed installations.
- the extendable barrier on casters consisting of modular elements pivoting therebetween in light alloy treated anti-corrosion all identical, each comprising two vertical branches in the shape of X pivoting on a rod in their center and at their ends on the next element, making it deployable and foldable manually;
- the barrier end elements are each provided with fixing means, preferably lockable, each on a corresponding fixed point for its immobilization in the deployed position between said fixed points integral with the site or attached in the form of a metal pole provisionally anchored or dei tively on this one.
- the two ends of said barrier may each be terminated by a complete modular element in X, these ends each comprising either two or four fixing means in the deployed position on a corresponding fixed point of the site, said fastenings acting together as a deployment limiter of the barrier and lateral stabilizers. Its two alternative ends each end in a special modular element formed by a normal half-element in Ne pivoting in a triangle provided, at its pivoting end, with at least one means of fixing the corresponding fixed point of the site.
- Its means of limiting deployment between two site attachment points is constituted by at least one chain stretched between two successive modular elements or by two identical links articulated between it and between two central pivots of two successive X modular elements.
- Each of its rollers is fixed to the end of a rod sliding in a tube integral with the corresponding modular element, comprising an upper stop defining the normal retracted position of each of the rollers, the low position, variable depending on the elevation of the site, being maintained by a self-locking means on the caster rod both in the low position and in the high position, which allows it to be supported on uneven ground over any its length.
- the reinforcement of this stability is obtained by means of the assembly of modular elements comprising two vertical X-shaped branches pivoting in their center, including the two branches of a same side are extended by one step beyond the end of the branches of the normal module, said extended branches having a 4th pivot at their extended end for attachment to the next identical module or to a special end module.
- its special end modules comprise a branch of the normal modular element cooperating with a branch of the special modular element so that said branches of this special modular element terminate on the same vertical plane perpendicular to the longitudinal axis of said barrier, the free end of the branch of the normal module pivoting on a short branch also pivoting at the end of the extended branch of the previous modular element, said ends each being provided with fixing means with or without locking on the fixed part of the site for the immobilization of said barrier.
- its two special end modules comprise two branches of the normal modular element cooperating with a branch of the special module and a short branch the length of a step so as to form an end triangle provided with a fixing means on a fixed point of the site, the other end of said reinforced barrier being able to be symmetrical or identical to the other.
- the main branch of the modular elements comprises a U-shaped profile provided with means for clipping a handrail profile. Bars are fixed between two portions of this profile which has holes for the passage of the pivot rods fixed thereon.
- the secondary branches of the modular elements are formed with two portions of a U-shaped profile comprising means for clipping a cover. This profile is pierced with fixing holes of the bars and, in line with the joints, has a punched hole for the passage of a bar through which the pivot rod passes.
- the bars are of rectangular section with rounded angles, the middle of the inner face of its two short sides has a fixing socket by means of four screws between the profiles of the main and secondary branches.
- the ends of the secondary branches comprise a retractable shoe support system on the ground provided with a means of rapid immobilization in the rest position or support to the floor.
- the barriers are produced by assembling as many normal or special modular elements in X, as necessary with their end elements comprising their fixing means which can be locked by padlock or lock.
- the yoke is extended by a threaded rod engaged in a hole in a metal plate and locked by means of four nuts after interposition on each side of the plate of conical washers to absorb the forces exerted on the barrier.
- the main uses of the barrier according to the invention are as follows: access ban; pedestrian crossing filtering to a site; separation of zones between them; insulation of objects, location or devices; orient, channel people, animals, vehicles etc.

- FIG. 26 shows an example of a means for fixing and locking two barrier sections together.
- the normal part 95 for closing the end of each of the facing sections 16 is extended outwards by a plate 96 pierced with a large hole 97.
- a connection plate 98 is made integral with the one of the closing pieces 95 by means of a bolt 99, the nut 100 of which is crimped, for example, by three needle punchs at 120 °.
- the fixing is ensured by a shouldered rod engaged in the holes of the other part 96 and of the plate 98 however that a padlock 102 and engaged in a hole 103 drilled in the end of the rod 101 preventing an unauthorized opening.
- FIG. 27 shows an example, seen in elevation, of a locking attachment of the end of a barrier 105 on a metal post 106 anchored provisionally or permanently on the site.
- the closing part 95 is taken in a yoke 107 in which the rod 101 is engaged and locked by a padlock 102.
- the yoke 107 is extended by a threaded rod 108 engaged for example in a hole in the core 109 of the U-shaped post or H or a metal plate 109 secured to a wall or the like.
- This rod 108 is blocked on said plate after adjusting the position of the yoke relative to the barrier by means of four nuts 110 after interposition on each side of the plate 109 of conical washers 111 for damping the forces exerted on the barrier.
- Figure 28 shows, seen in writing, the pivoting detail of a secondary branch on the end pivot of a main branch of the modular elements of the barrier according to the invention.
- the reference numbers of the preceding figures were used for the same members.
- This figure provides a better understanding of the mounting of the main and secondary branches on their pivot.
- the bar 15 can also be crimped , but this is not necessary since it is in abutment on each side on the corresponding fins of the profiles 20 and it receives two bearings 64 of the pivot rod 65.
- the spaces between the bars 17 and 18 of the barrier can be closed by various means such as cladding sheet, corrugated sheet, opaque, transparent or translucent plastic panels, laminated glass or light ribbing. These closing means can be perforated except for the glass. These various closing means can be inserted into seals embedded in small standard U-profiles in light ribbing, treated against corrosion, fixed on the short sides of the bars.
