A bracket (1 and 1') for safety devices comprising a vertical prop (2), perpendicular to whose base is welded a sleeve (3) accommodating a crossbeam called lower (4) which ends in a cap (5) and which can be immobilised in its movement by a pin (8), and at the upper part of the said prop are fixed : - on the one hand, by one (11) of its ends, a crossbeam (12) which extends on the side opposite to that where the lower crossbeam (4) has its cap (5), and whose other end (13) is supported by a brace (14) which in its turn rests on the base of the prop (2), and - on the other hand, on the side where the lower crossbeam (4) has its cap (5), a sleeve (24) whose front face has a cutout (18) for working in conjunction with a rod (19) anchored in the wall, this sleeve with a vertical axis being capable of accommodating a vertical bar (25, 48) ending at its upper part with a fixing means such as a plate having a cutout similar to that of the carrier (16) and which can be immobilised in its vertical movement by a horizontal pin (26) crossing a perforation (27) of the sleeve and one of the perforations of the vertical bar (25, 48), this bracket being characterised in that : - the sleeve (24) is formed by a carrier (16) whose back has the cutout (18), - the rod (19) is provided with a stop member (20) which is located between the arms (21, 22) of the carrier (16), - the perforation (27) of the sleeve (24) is positioned in such a way that, when, instead of suspension by a vertical bar, the bracket is directly suspended on a rod (19) passing through the cutout (18) of the back of the carrier (16), the placing of this pin (26) causes it to pass just under the stop member (20) in such a way that it then prevents the rod (19) from being detached from the cutout (18) and at the same time prevents the rotation of the said stop member (20), and - the arms (21, 22) of the carrier (16) each have at their base a cutout (29) in the form of a hook capable of covering a horizontal rail (30).

Description

The invention relates to a device console of

  such as bridges, guardrails and safety nets that are to be attached to a construction for

  facilitate the continuation of the realization or the maintenance.

  It also relates to safety devices

  of this type including such consoles and more particularly

  but not exclusively to those formed by assembling elements of importance and therefore of limited weight to

portable manually.

  We already know many consoles meeting this requirement and that we can classify according to their mode of attachment in three main types namely those which are fixed by support in a gutter then those which are suspended either by pierced legs receiving rods perpendicular to the wall in which they are anchored, or by hooks cooperating with a horizontal bar

  sealed against the wall and generally referred to as smooth.

  The consoles which are fixed by support in a gutter comprise a vertical upright perpendicularly to which are, at different levels, welded two mutually parallel sleeves and guiding in translation two sleepers of which that of the lower level sheath is directly terminated by a clevis carrying a support pad on the wall below the gutter while that of the upper level sleeve is terminated by another sleeve meanwhile parallel to the upright and guiding in translation a finished punch at its base by a clevis bearing a support pad sure

the bottom of the gutter.

  Translations of sleepers and punch make it possible to adjust the console to adapt it to the particularities of the construction.

  For use, they are then made impossible to

  sibles by removable pins through the sleeves

and crosses them or punch them.

  These consoles generally receive a guardrail which is then fixed on extensions of their amount which rise for this purpose clearly above their upper crossbar which, in turn, may receive a

2 2554856

  floor. The brackets that hang by suspension to rods perpendicular to the wall in which they are anchored

  comprise (FR-A-2,488,311) a vertical upright perpendicular to

  the base of which is also welded a sheath guiding a cross member terminated by a clevis adapted to maintain said base at a predetermined distance from the wall by a pad or other means such as a stay fixed between the tables of a window while at the upper part of this amount are fixed: - on its rear side, a horizontal crossbar of which,

  so that it can support a floor and / or

  de-body or protective net, the rear end is itself supported by a strut taking for its support to the base of the amount and - on its front face, a plate parallel to the wall and having a bore or a cut slightly wider than the diameter of the rod anchored in the wall and provided with a stop member such as a screw head or a nut located behind the plate and pressing the face

back of it.

  In an alternative embodiment, instead of a plate directly attached to the amount thereof is formed by the bottom of a rider whose bottom and branches are made with the front of the amount, a sheath axis parallel to said upright and in which can be housed a riser completed by a plate of the type mentioned above, thanks to which, without the riser, we can always fix the console on the rod whose stopper will find place in the rider and, with the enhancement, we can catch an anchor

  located higher and for example under a roof overhang.

  To lock the whole thing, a pin passes through

  the rider's arms to such an extent that, if there is an extension, it also passes through this riser while, if there is no extension, it advantageously passes just under the stopper for prohibit both and the release of the rod and the rotation of this stopping organ and

therefore the loosening of the fixation.

  The brackets which are suspended by hooks cooperating with a horizontal arm sealed against the wall are similar to those above, except for the plate or the jumper which is here replaced by hooks able to comb the smooth sealed to the wall.

  So, these three types of consoles differ primarily

  cipalement of each other at their fixing device which requires in the first type a sliding cross member along an axis perpendicular to the wall, in the second type the possibility of a sliding extension along the a vertical axis and in the last type a possibility of attachment at different points along the length

  a smooth horizontal axis parallel to the wall.

  As a result, to date, depending on the constructions in which they operate, the contractors must have consoles specially adapted to each of these three modes of operation.

  which, of course, triples the cost and

  equipment and, incidentally, the cost price

construction.

  A result that the invention aims to obtain is a console that can be fixed indifferently by support in a gutter, by suspension to rods anchored in the

wall or suspension to a rail.

  For this purpose, it relates to a console of the type mentioned above, in particular characterized in that the branches of the

  rider each have at their base a sensitive cut-

  in a semicircle giving them a hook shape adapted to cap a horizontal beam suspended by legs fixed by screwing on anchor points provided in the wall. It also relates to safety devices

including such consoles.

  The invention will be well understood with the help of

  cription hereinafter made by way of non-limiting example, with reference to the attached drawing which shows schematically: - Figure 1: the console view in perspective with in phantom the three fasteners,

4-2554856

  - Figure 2: a section through the axis of the superstructure

  bracket where the attachment is on a rail,

  - Figure 3: a section through the axis of the upper crossbar

  top of the console in the case where the fixing takes place by support in the gutter, - figure 4: a section through the axis of the sleeve at the base of the console,

  - Figure 5: a section through the axis of the superstructure

  console in the case where the support in the bottom of the gutter is at a level much higher than that of the upper rail and for example to bypass a

acroterium or cornice.

  Referring to the drawing, we see that, like a console suspended from a rod or a rail, each

  bracket 1, 1 'comprises a vertical upright 2 perpendicular

  at the base of which is welded a sheath 3.

  This sheath guides in translation a cross 4 terminating

  born by a clevis 5 called for example to receive a shim 6

on a wall 7.

  The distance between the yoke 5 and the upright 2 is adjusted by sliding the cross member 4 in the sleeve 3 in

  which is then immobilized by an 8-pin

  pouring a piercing 9 of the sheath 3 and one of the pergages 10 of

the crossbar 4.

  At the upper part of the upright 2 is fixed by one of its ends 11 a horizontal cross member 12 whose other end is supported by a strut 14 itself taking support at the base of the upright 2 and directly or by the intermediate of the sleeve 3 of the lower cross member 4. The upper cross members 12 of at least two consoles then make it possible to establish a floor 15 and / or fix by any known means the feet (not shown) of a guardrail

or a safety net.

  On the side where the lower crosspiece 4 carries the yoke, the upper part of the upright 2 carries, directly or through said upper cross member 12, a jumper 16 whose bottom 17 has a cutout 18 such a

  drilling or a "U" shaped light of slightly greater width

  than the diameter of the rod 19 anchored in the wall and

  view of a stop member 20 such as a nut which is placed between the branches 21, 22 of the rider which carries with the front face 23 of the part 12 on which it is fixed a

  sleeve 24 of vertical axis, and therefore parallel to the amount 2.

  This sleeve 24 can then receive and guide in trans-

  vertical section a vertical bar called "raises" 25 completed at its upper part by a plate (not shown) having a cutout similar to that 18 of the

bottom 17 of the rider 16.

  A horizontal pin 26 of axis parallel to the wall, then passes through a hole 27 of the branches 21, 22 of the rider

  as well as one of the holes 28 of the enhancement for the immo

  biliser in translation with respect to the sheath 24 when its

position is correct.

  The persage 27 executed in the rider to receive

  this pin. 26 is positioned in such a way that, when

  that instead of a suspension by a riser, the console is directly suspended from a rod passing through the cutout 18 of the bottom of the rider, the establishment of this pin passes just under the stop 20 such a nut, so that it then prevents both the release of the

  cutting rod and the rotation of said stop member 20.

  According to one characteristic of the invention, the branches 21, 22 of the rider 16 each have, at their base, a cutout 29 substantially in a half circle giving them a hook shape adapted to cap a horizontal beam 30 suspended by legs (not shown ) themselves fixed by screwing on anchor points provided in the wall. The lower edge 31 of the bottom 17 of the rider 16 preferably descends to the bottom of the rail to form a wide

stop.

  To prevent shaking, the console emerges from the rail, according to another feature of

  the invention, the rider carries a lock 32.

6 2554856

  This lock consists of a plate 33 applied against the outer face of at least one of the branches of the

  jumper and having at its base a light "C" 34 or-

  green at the front so that its lower branch 35 engages under the smooth 30. This lock is articulated at its upper part

around an axis 26.

  Preferably, the lock 32 comprises, applied each

  one against the outer face of one of the branches, two plates 33 of the above type and these plates are interconnected by a cross member 36 arranged in such a way that, when the lock retains the rail, the cross member 36 is

  resting on the floor 15 to prevent its lifting.

  According to another characteristic of the invention, with respect to the vertical plane containing the center of gravity 37 of the lock 32, the axis 26 of the lock is deported to the bottom of the rider so that, by gravity, the rider tends

  automatically to move to the locked position.

  The lower edge 38 is connected to the nose 39 of the branch

  lower che. 35 of the lock 32 by a wide chamfer 40 realizing a ramp automatically releasing the lock 32

when pressing on the smooth 30.

  According to another characteristic of the invention, the axis of the lock is constituted by the pin 26 passing through the same bore 27 of the branches 21, 22 of the rider that for

  immobilize the extension 21 or the nut 20 of the rod 19.

  According to a feature of the invention, on the one hand, the front end 23 of the upper cross member 12 of the console is open and, on the other hand, the rider 17 presents

  in the fictitious continuation to the front of the inter-

  from the top rail, clearance 41 at least

  sufficiently important to allow the aforesaid

  fictitious situation towards the front of the internal section of the

  upper pour, which, therefore, is adapted to house a slide 42 which can project to the front of the console and be immobilized in a suitable position by a pin 43 through a channel 44 of the cross and one

blinds 45 of the slide.

  This slide can for example be worn at its end.

  before a sheath 46 parallel to the upright and housing a punch 47 completed at its base (not shown) by a clevis

  provided with a support pad in a gutter.

  In the case where the gutter is located at a net

  higher or when it is necessary to circumvent a parapet or cornice, the assembly formed by the sleeve 46 and the punch 47 may, with its slide 42, be carried by a sleeve (not shown) carried at the head of a vertical bar called "false-amount" 48 which, in the manner of the extension 25, is engaged and immobilized in translation in the jumper 17 which, in the corresponding case, is free of

all enhances.

  In this case, in a preferred mode, the false amount is also locked in the yoke 5 of the cross member

  4 of the console, using a 49 tooth pin

  pouring a hole 50 of the yoke and one of the holes 51 of the

false amount 48.

  Preferably, the yoke 5 is dimensioned such that the row of bores 50 can be aligned with

  that of the persages 28 receiving the pin 26.

  Wall support is then provided by a set of

  ble (not shown) sheath and cross with a shoe of the type of those 3, 4, 5 and 6 described above, but worn by the

false amount 48.

  Thus produced, the same console can cooperate with fastening means in relation to bars or sleepers along three axes X, Y and Z perpendicular to each other. In addition to the three attachment possibilities mentioned above, when they are in direct support in the gutter or suspended from rods perpendicular to the wall and engaged

  in the rider's cutouts, these consoles allow us to

  use the cutout 29 and the locking latch 32 of the rail to block a spacer tube of the consoles and / or

  to build a cantilevered floor.
