  • the invention concerns an extending barrier on wheels consisting of various swiveling modular elements, deployable and folding manually.
  • the extending barrier wheels consisting of modular sections pivoting between one another of light alloy, anti-corrosion treated, all identical and each comprising two vertical X-shaped arms swiveling on a pin at the center and at the ends on the following element, rendering it extendible and folding manually;
  • the end elements of the barrier are each provided with attaching means, preferably locking, each to a corresponding fixed point for immobilization in the extended position between said fixed points integral with the site or added in the form of metal posts anchored provisionally or definitively to it.
  • the two ends of the barrier may each be terminated by a complete X-shaped modular element, these ends having each either two or four means of attachment in the extended position to a corresponding fixed point on the site, with said attachments working together as a limiter for the deployment of the battery, and acting as side stabilizers.
  • the means of limiting deployment between two attaching points on the site comprises at least one chain tensioned between two successive modular elements, or yet again by two identical connecting rods articulated between one another and between two central pivots comprising two successive X-shaped modular elements.
  • Each of these wheels is attached to the end of a pin sliding in a tube integral with the corresponding modular element, comprising a high stop defining the normal retracted position of each wheel, while the low position, variable according to the difference in level of the site, is maintained by a self-locking means on the pin support, both in the low and in the high position, so that the barrier can be extended over the entire length over an unequal ground surface.
  • the stability is reinforced by an assembly of modular elements comprising two vertical arms forming an X, swiveling at the center in which the two arms on the same side are extended one step beyond the end of the normal module arms, which extended arms have a fourth pivot at the end, extending for their attachment to the following identical module or to a special end module.
  • the special end modules When formed by an assembly of modular elements with reinforced lateral stability, the special end modules include an arm of the normal modular element working together with an arm of the special modular element so that the arms of this special modular element terminate in the same vertical plane perpendicular to the longitudinal axis of said barrier, while the free end of the normal module arm pivoting on a short arm, also pivoting at the end of the extended arm of the previous modular element, said ends each being provided with means of attachment with or without a lock in the fixed part of the site, for immobilizing said barrier.
  • the main arm of the modular elements includes a U-shaped profile provided with means of clipping on a handrail profile.
  • the bars are fixed between two portions of this profile, which includes holes for the passage of pivot rods attached to them.
  • the secondary arms of the modular elements consist of two portions of a U-shape profile comprising means of clipping a cover in place. This profile is pierced with bar attaching holes and at the articulations, has a punched hole for the passage of a bar through which the pivot pin passes.

Bars 17 (not shown) are attached between profiles 16 defining their horizontal position; pin 65 is inserted in the corresponding holes of the profiles with nuts 66 , 67 installed and approached between profiles 16 at the same time together with washers 68 and 69 leaving slight play between nuts 66 , 67 and washers 68 , 69 to allow arm 15 to pivot smoothly on bearings 64 of pin 65 . Flat washers 70 and lockwashers 71 are placed on threaded ends of pin 65 , and nuts 72 are locked against their washers, immobilizing pin 65 on the main arm.
  • FIG. 23 shows an example of the attachment of bar 17 between two profiles 16 or 20 forming arms 14 and 15 of the various modular elements. Attachment is by four self-tapping screws 75 inserted in the profile passages holes and secured in the screw recesses 60 of the bars. This attaching mode considerably strengthens resistance of the barrier to longitudinal deformation during opening and closing maneuvers. The bars can also be swaged as shown in FIG. 28.
  • FIG. 24 shows a sectional view example of a removable floor bearing plate system mounted at each outer pivot of the barrier to compensate for differences in site level, or for curb crossings. It includes a tubular sleeve 80 in which a pin 81 slides vertically over shoulder 82 and lower bearing 83 . A bearing plate 84 is attached to lower end of pin 81 . There is a compression spring bearing between bearing 83 and shoulder 82 . Locking lever 86 , hinging at 87 on the system support, has a hole slightly larger than the diameter of the plate pin, so that the edge of the hole locks it in the high or low position under the thrust of spring 88 . This system is mounted to be removable on an end bar and abut at the end of lower profile 20 .
  • FIG. 25 is a schematic top view of an example of a long barrier according to the invention, consisting of several sections 90 , 91 , 92 to be assembled on site by means of lock 93 .

  • the normal part 95 closing the end of each of the profiles 16 facing each other is extended on the outside by a plate 96 drilled with a large hole 97 .
  • An interconnecting plate 98 is made integral with one of closing parts 95 through a belt 99 whose nut 100 is crimped, for instance by three hammer strokes at 120°. Attachment is then provided by a shouldered pin engaged in the hole of the other part 96 and plate 98 , while a padlock 102 is inserted into a hole 103 drilled into the end of pin 101 to prevent unauthorized opening.
  • FIG. 27 is an elevation example view of a lockable attachment at the end of barrier 105 on a metal post 106 anchored provisionally or definitively on site.
  • Closing part 95 is held in a clevis 107 , in which pin 101 is engaged and locked by a padlock 102 .
  • Clevis 107 is protected by a threaded pin 108 engaged, for instance, in a hole in web 109 of the U- or H-shaped post, or a metal plate 109 integral with a wall or other support.
  • This pin 108 is locked to said plate after the position of the clevis has been adjusted with respect to the barrier for four nuts 110 with, interposed on either side of plate 109 , tapered washers 111 to dampen the forces applied to the barrier.
  • FIG. 28 is a perspective view of a detail of the pivot in a secondary arm on the end pivot of a main arm of the modular elements of the barrier according to the invention.
  • the figure callout numbers used above have been used for the same devices.
  • This figure gives better understanding of the assembly of the main and secondary arms on their pivots.
  • Bar 15 can also be swaged, but this is not necessary because it abuts at either end of the corresponding flanges of profiles 20 and receives two bearings 64 of pivot pin.
  • the gaps between bars 17 and 18 of the barrier can be closed by a variety of devices such as cladding sheet metal, corrugated iron, opaque, transparent or translucent plastic panels, laminated glass or light alloy. These fillers can be cut out, except in the case of glass. These various means of closure can be inserted into beading fitted into the small standard light alloy profiles with anti-corrosion treatment, attached to the small sides of the bars. These panels could be provided as a support for advertising posters.
