Description

1 2754574

  The invention relates to a device for assembling a first fixed upright and a second removable upright. The first upright is of the type comprising towards each of its ends, respectively upper and lower, at least one upper support tab and at

  minus one lower support leg.

  The second upright is of the type comprising at least one upper fixing member and at least one lower fixing member, intended to cooperate with the tabs

  upper and lower supports respectively.

  The invention also relates to a post, acting as a first fixed upright, and a panel, comprising two uprights acting as a second removable upright,

  intended to be assembled by means of such a device.

  Finally, the invention relates to a protective barrier comprising at least one panel arranged vertically, assembled on either side with two posts.

  fixed, by means of the above-mentioned assembly device.

  The invention is more particularly intended for the protection of machines, especially dangerous machines, but can

receive other applications.

  One of the problems which arises for this type of protection is the rapid dismantling of the panel, without the intervention of a third person, or of particular tools.

2 2754574

  Generally, the panels of such a protective barrier are fixed to the posts by means of

  two means forming screwed hinges.

  To remove the panel, it is therefore necessary to dismantle each of the hinges one by one. In addition, the loss of screws can be frequent, this

  which is problematic to mount the panel again.

  The invention therefore aims to remedy these various drawbacks. To this end, it offers an assembly device allowing the mounting and dismounting of a panel, in particular for protective barriers, easy, quick, non-dangerous and for which the screws are captive. Thus, the invention provides an assembly device of the aforementioned type in which the upper support lug is associated with the upper fixing member by removable fixing means, and in that the lower support lug is associated with the member lower fixing by support and guide means, capable of supporting and guiding in tilting the second upright when the upper fixing member is dissociated from the

upper support tab.

  The second upright, and in particular the panel comprising it, assembled to the first fixed upright, is thus

  made tilting and removable at the bottom.

3 2754574

  It therefore suffices to disassemble the assembly in part

  upper to be able to remove the panel or upright.

  Other features and advantages will be better

  understood in light of the following description, in

  reference to the drawings given by way of nonlimiting examples. Figure 1 shows an exploded view of a first embodiment of the assembly device of the invention, a post and one of the uprights of the panel

being partially represented.

  FIG. 2 represents an exploded top view of the first embodiment of the device, shown in

Figure 1.

  Figure 3 shows an exploded top view of a second embodiment of the device of the invention. Figure 4 shows a partial view in

  elevation, of a protective barrier of the invention.

  Finally, Figure 5 shows a side view of a

  panel assembled to a post, in the tilted position.

  In one embodiment of the invention, the protective barrier comprises a plurality of posts 1, arranged with their axis vertical. The posts 1 are fixed to the ground S and support, between them, protective panels 2, mounted by means of an assembly device 3, on which

we will come back later.

4 2754574

  A partial view of the protective barrier is shown in Figure 4, where two posts 1 are fixed to the ground S with a first panel 2 between them, a second panel 2 being mounted to one of the posts 1, on the other side of the first panel 2. The posts 1 considered here are straight and

  the panels 2 are generally flat and planar.

  In other possible embodiments, a post 1 can have several sections parallel to each other,

  following, eccentric, one in relation to the other.

  Such an embodiment allows for example to

around an obstacle.

  Similarly, a panel 2 can, in other

  achievements, be curved so as to form an angle.

  The posts 1 and the panels 2 are preferably made of metal, protected if necessary from corrosion or coated with a paint

  decorative, or a protective material.

  Optionally, they can be made of a suitable plastic material meeting the requirements of

resistance desired.

  A protective panel 2 includes a frame

  4 placed on the periphery of a mesh or equivalent 5.

  In the embodiment considered, the grid 5 has rectangular meshes and is

  made from metal wires.

2754574

  Other constructions are possible without

  depart from the scope of the present invention.

  The frame 4 comprises a first and a second upright 6a, 6b, intended to be placed vertically when the system is mounted, and two crosspieces, respectively high and low 7a, 7b, connected perpendicularly to the uprights 6a, 6b by their ends. In the most general case, shown in Figure 4, a post 1 is interposed between two panels 2 placed

from either side.

  Where appropriate, a post 1 may be associated with only one panel when, for example, this post is

himself placed against the wall.

  The post 1 comprises a main core 8, extending along the axis la, and, rigidly integral with the latter, support legs 9a, 9b forming

  part of the assembly device 3.

  Referring to Figure 1, the core 8 has in cross section, a general hexagonal or pseudo-hexagonal shape. More particularly, it has a flattened shape symmetrical with respect to the axis la, and more particularly with respect to a median plane P comprising

said axis la.

  For this purpose, the core 8 is defined by two large walls 10 and four small walls 11 which connect, by two pairs, the two large walls 10. The median plane P is parallel to the large walls 10 and includes the edges 15

6 2754574

  formed by the junction of the small walls 11 of each pair. The two large walls 10 have the same dimension,

  are parallel and placed opposite one another.

  The small walls 11l have the same dimension. In addition, the two small walls 11 of each pair are inclined relative to each other with a

  angle a for example of the order of 90.

  In other embodiments, this angle is understood

between 30 and 60.

  Consequently, a large wall 10 and a small adjoining wall 11 are inclined relative to each other at an angle of the order of 135 but which can be

  included in other designs between 120 and 150.

  In a particular embodiment, the width -

  counted parallel to the median plane P and perpendicular to the axis of the large walls 10 is equal to or of the order of 70 mm and that of the small walls 11 equal to or of the order of 24 mm. The ratio of the widths between a large wall 10 and a small wall 11 is therefore

the order of 3.

  Furthermore, the spacing between the two large walls 10, -counted perpendicular to the plane P- is of the order of half the width of these same large walls 10. This overall spacing is therefore, in

  the occurrence, equal to or of the order of 35 mm.

7 2754574

  According to one embodiment and in particular when the post 1 is made of metal, the core 8 is hollow. In such an embodiment, the core 8 has an equal thickness or

around 3 mm.

  At one of its ends, the post 1 comprises a fixing plate 12 integral with the core 8, intended to be fixed to the ground S. In the embodiment shown, this plate 12

  extends transversely to the axis la.

  Other embodiments are possible in which the plate 12 is replaced by a device

equivalent anchor.

  Such a plate 12, like the support legs 9, can be made of metal and the attachment to the core 8 can

be made by welding.

  A support tab 9a, 9b is provided with a through hole 13 with an axis parallel to the axis la and with at least one tapped hole 14, transverse to the through hole 13, opening into the through hole 13, and at the opposite in

  the peripheral face of the support leg.

  The tapped hole 14 thus comprises two sections

  on one side and the other of the through hole 13.

  In this case, a support tab 9a, 9b is attached to a pair of small walls 11 by overlapping their junction line 15 forming an edge of the

post 1.

8 2754574

  More particularly, a support tab 9a, 9b extends towards the outside of the core 8 in the median plane of symmetry P. A support tab 9a, 9b has, perpendicular to the plane P, overall dimensions less than the overall dimensions of the post 1 between its two large walls 10. This structure is particularly good

visible in Figures 2 and 3.

  Such a support tab 9a, 9b can be produced

in one-piece metal.

  In the embodiment shown, it is limited by two faces 16a substantially parallel to the plane P, a rounded end 16b opposite the edge 15 and a re-entrant dihedral 16c capable of pressing against

  the core 8 by overlapping the edge 15, as already indicated.

  The faces 16a, the rounded 16b and the re-entrant dihedral 16c thus define between them two faces, respectively upper 16d and lower 16th, intersecting in the median plane P and extending substantially perpendicular to the median plane P, the lower face 16e being opposite of the ground S. As follows from the above, the spacing between the two faces 16a is substantially less than the spacing between the two large walls 10,

  for example of the order of half.

  The through hole 13 is disposed away from the edge 15 by a value equal to at least half of

the thickness of the panel 2.

9 2754574

  When a post 1 is intended to support two panels 2, the post 1 has four support legs 9a, 9b, namely a pair on one side, that is to say on a

  edge 15- and a pair on the other side of the post 1 -it is-

  that is to say on the other edge 15, the legs 9a, 9b being located in the median plane P. The upper support legs 9a and lower 9b of the same pair are each arranged towards one end,

  respectively upper 8a and lower 8b of the core 8.

  More specifically, the lower 9b and upper 9a support legs of the same pair are spaced apart from one another along the edge 15, their through hole 13

  being arranged opposite one another.

  When a post 1 is intended to receive a single panel 2, it may only be provided with a single pair of support legs 9a, 9b, these facing one of

  the other and spaced along edge 15.

  With the preferred embodiment described above, the spacing between the two edges 15 is equal to or of the order of 105 mm, while the spacing between the axes of the through holes 13 located on either side of the

  post is equal to or about 125 mm.

  As will be seen later, the through hole 13 has the function of allowing the mounting of a connecting piece 17 forming part of the device

assembly 3.

  The threaded hole 14 has the function of fixing a locking screw 18 of said connecting piece 17

2754574

  also part of the assembly device 3 provided

for this purpose.

  Preferably, the panel 2, and more precisely its frame 4, has an overall size which is substantially equal to the overall spacing between

the two large walls 10.

  The panel 2 comprises, on each of its uprights 6a, 6b, a pair of fixing members, respectively

upper 19a, lower 19b.

  The upper fixing member 19a is intended to cooperate with the upper support tab 9a of a post by means of removable fixing means, which will be

described later.

  The fixing member 19a, located towards the upper end of an upright 6a, 6b, when the panel 2 is mounted, is in the form of a fixing lug, projecting from the side opposite the grid 5, substantially in

  the extension of the upper cross member 7a.

  This fixing lug 19a is in the form of a substantially planar wall, adjoining and substantially parallel but offset relative to the median plane P 'of the upright 6a, 6b, which is substantially parallel.

  or confused with the general grid plan.

  This tab 19a is provided with a threaded through hole 20, the axis of which is substantially

perpendicular to the median plane P '.

  l 2754574 In the embodiment shown, the fixing member 19b corresponds to the hollow end piece

lower of the amount 6a, 6b.

  Indeed, the uprights 6a, 6b of the panel 2, visible in Figure 1, have a hollow profiled shape and a cross section in the form of

  parallelogram, and more precisely square.

  Thus, the lower fixing member 19b is

coaxial with the amount 6a, 6b.

  The lower fixing member 19b is intended to be associated with the lower support tab 9 of a post 1, by support and guide means 21, forming part

of the assembly device 3.

  These means 21 are such that they allow the support and the tilting guidance of an upright 6a, 6b of the panel 2, when the upper fixing member 19a is

  dissociated from the upper support leg 9.

  In the embodiment shown in FIG. 1, these support and guide means 21 are in the form of a piece forming a square, substantially L-shaped and defined by two substantially planar walls 21a,

  21b, perpendicular to each other.

  One of the walls 21a has a tapped through hole 22 whose axis is substantially perpendicular to

said wall 21a.

  The wall 21a is intended to come against the face

  lower 16th of the lower support leg 9b.

12 2754574

  In this position, the through hole 22 comes opposite the through hole 13 of the lower support lug 9b and receives therewith a connecting screw 23, associated, where appropriate, with a washer 23a and a nut 23b. In addition, the second wall 2lb of the piece forming a square 21 is turned substantially towards the upper support tab 9a and is capable of receiving the lower fixing member 19b, in this case in the embodiment shown, the lower end hollow of the upright 6a, 6b. Thus, as shown in FIG. 5, when the panel 2 and the post 1 are not fixed at the top, the panel 2 is supported by the piece forming a square 21 and can tilt in a plane transverse to the

median plane P of column 1.

  It is also possible and simple to remove the

  panel 2 of the part forming a square 21 by lifting it.

  As previously indicated, the assembly in the upper part of a post 6a, 6b and a post 1

  is permitted by removable fixing means.

  These means include in particular a connecting piece 17 comprising an elongated body of revolution 17a intended to be introduced into the through hole 13 of the upper support tab 9a while being held in place by a locking screw 18, screwed into the tapped hole 14 of

said support tab 9a.

13 2754574

  The connecting piece 17 further comprises a head 17b, intended to come into abutment against the underside

16th of the support leg 9a.

  The head 17b is furthermore pierced with a threaded through bore 17c, perpendicular to the axis of the body 17a, capable of cooperating with the threaded orifice 20 of the tab.

  fixing 19a, by means of fixing 24.

  In the embodiment shown, the connecting piece 17 is a pin. It allows in particular the rotation of the panel 2, and more precisely of the amount 6a,

  6b, around the axis of the pin 17.

  One could nevertheless plan to use a screw

instead of the trunnion.

  In addition, it could be envisaged that the connecting piece 17 does not exist, and that the bore 17c is provided

  in the upper support tab 9a.

  In this case, the panel 2 would remain fixed by

compared to post 1.

  The fixing lug 19a is intended to come against one of the faces 16a of the upper support lug 9a, with its orifice 20 facing the bore 17c of the

connecting piece 17.

  The fixing means 24, enabling the fixing lug 19a to be assembled to the connecting piece 17, comprise a fixing screw 25, and preferably,

a washer 26.

14 2754574

  The fixing screw 25 has a low-cut portion 25a of longitudinal dimension 1 sufficient to be held either in the threaded orifice 20 of the fixing lug 19a, or in the threaded bore 17c of the connecting piece 17. In addition, the longitudinal dimension of the threaded portion 25b of the fixing screw 25 is such that it cooperates respectively with the threaded bore 17c, or with

the tapped hole 20.

  The washer 26 is also intended to be placed on the low-cut part 25a, at the junction

  between the low-cut part 25a and the threaded part 25b.

  The washer 26 is preferably made of plastic. It prevents the fixing screw 25 from biting

in his stripe.

  Two types of fixing screws 25 are therefore used for assembling the panel 2 to the post 1, along the side

  of panel 2 on which it is desired to make the attachment.

  In a first embodiment represented in FIGS. 1 and 2, the assembly is carried out on the side of the

fixing lug 19a.

  Thus, the low-cut part 25a of the fixing screw 25 is received by the orifice 20 and has a length 1 - counted along the axis of the screw 25 - equal to the depth of the orifice 20 - counted along the axis orifice 20-, added, if necessary, to the thickness of the

washer 26.

2754574

  In addition, the threaded portion 25b of the screw 25 is introduced into the bore 17c and has a length substantially equal to the depth of the bore 17c of the

connecting piece 17.

  In addition, according to a second embodiment represented in FIG. 3, o the assembly is carried out by the face 16a of the upper support lug 9a, opposite to the face 16a against which the fixing lug 19a rests, the low-cut part 25a of the fixing screw 25 is received by the bore 17c and has a length 1 substantially equal to the depth of the bore 17c, added, if necessary

  where appropriate, to the thickness of the washer 26.

  Furthermore, the threaded part 25b of the fixing screw 25 is introduced into the orifice 20 and has a length substantially equal to the depth of

  the orifice 20 of the fixing lug 19a.

  The use of two different fixing screws 25 is made possible by the fact that the orifice

  and bore 17c are both tapped.

  This characteristic makes it possible to assemble a panel 2 to a post 1 from the outside or from the inside of the

protective barrier.

  The method of mounting the panel 2 on the post 1 consists of: 1 / assembling the wall 21a of the piece forming a square 21 to the lower support tab 9b by means of the assembly screw 23, and possibly a washer 23a

16 2754574

  and a nut 23b, the wall 21b being turned towards the upper support tab 9a; 2 / fitting the lower fixing member 19b with an upright 6a, 6b of the panel 2 on the wall 2lb; 3 / thread the connecting piece 17 into the upper support tab 9a through its through hole 13, leaving its head 17b protruding towards the ground; 4 / block the body 17a by means of the locking screw 18 screwed into the tapped hole 14; 5 / place the fixing lug 19a against a face 16a of the upper support lug 9a, with the orifice 20 and the bore 17c opposite; 6 / insert the fixing screw 25 and the washer 26 into the hole 20, or the bore 17c, then into the bore

  17c, or the orifice 20, depending on the assembly side chosen.

  Disassembly consists in following the opposite steps, starting by dissociating the fixing member 19a from the upper support tab 9a, the fixing screw 25 remaining in the bore 17c or the orifice 20 thanks to its part.

  neckline 25a, which makes it "captive".

  Then, the panel 2 is tilted relative to the pole 1 and it is lifted or pushed to remove it from the means

forming a square 21.

  Once the protective barrier is mounted, the panels 2 and posts 1 can be aligned in the same

17 2754574

  plane or inclined, or perpendicular, to each other

to others.

  Thus, the two posts 1 have their respective median plane P coincident, parallel or perpendicular to each other. In addition, the overall size of each

  post 1 is substantially equal to that of panel 2.

  Of course, other embodiments can be envisaged without departing from the scope of

the invention.

  For example, one can provide for the presence of two upper support legs, and possibly two

  lower support legs, arranged side by side.

  In addition, it can be envisaged that the lower support tab 9b has a shape substantially different from

the upper support tab 9a.

  Finally, the lower fixing member 19b could also have the shape of a square intended to cooperate with the piece forming a square 21, or even be either an added piece or a piece projecting from the side.

opposite the mesh 5.
