Definitions

  • the present invention relates to improvements made to the securing arrangements for, in a scaffolding, to assemble to a mast at least one element, such as a cross member or the like, extending approximately transversely thereto, which mast is provided with a receiving member open upwards and having at least one approximately vertical wall spaced radially from said mast and which element is provided, at its end to be assembled with the mast, of a clamping member integral with the element and capable of overlapping said wall of the receiving member, said clamping member having a first clamping surface cooperating with the inner surface of the wall and a second surface located outside the wall and spaced from the latter, at least one approximately vertical slot passing through said clamping member and emerging between the first and second surfaces mentioned above, and is also provided with a member movable locking in said slot to be engaged between the outer surface of the wall of the receiving member and said second surface of the clamping member.
  • a member such as a cross member or the like
  • the invention further relates to improvements made to the clamping members usable in a securing arrangement as defined above, as well as improvements made to the assemblies consisting of such a clamping member and a locking member.
  • the invention applies essentially, although not exclusively, to scaffolding and parts, in particular masts and sleepers or other similar parts, making it possible to constitute a scaffolding.
  • the wall integral with the mast on which the end of the cross member or the like is clamped has mutually parallel faces.
  • the clamping of the clamping member on this wall is then only a function of the amount of friction occurring between the cooperating surfaces; therefore, if the clamping member (or the cross member) is subjected to a sufficiently high lifting force (accidental shock for example) and greater than the clamping force dependent on friction, the clamping member may be inadvertently released of the receiving organ.
  • the faces of the wall of the receiving member are not parallel and diverge from one another upwards.
  • the structure adopted for the wall means that either it can deform under the action of a significant force and, then finding a configuration with approximately parallel faces, it cannot effectively retain the crosspiece, or it cannot s '' oppose a shaking of the link accompanied by an unlocking of the parts which can be dangerous.
  • the object of the invention is essentially to remedy, as far as possible, the various drawbacks of current arrangements and to propose an improved arrangement which better meets the various requirements of practice, while ensuring that it does not This results in no additional complications or higher costs for manufacturing, use and maintenance.
  • the retention of the clamping member on the receiving member - and therefore the joining of the element such as cross or ana mast mast - no longer dependent on the only clamping force exerted on the wall of the receiving member, but is mainly due to the curvilinear geometry of all of the cooperating parts which means that once the locking in position in the clamping member against the external face of the wall of the receiving member, it is impossible for the clamping member to be able to disengage inadvertently from the receiving member.
  • the locking member can be simply inserted without play, but also without force fitting between the outer surface of the wall of the receiving member and the second surface of the clamping member which are mutually parallel.
  • the second surface of the clamping member in particular, it too can be curved in an arc of a concavity turned towards the mast and be substantially parallel to the exterior surface of the wall of the 'receiving organ; or else be substantially planar and tangent to a surface substantially parallel to the exterior surface of the wall of the receiving member; or even be constituted in the form of a rod-shaped element.
  • the second surface of the clamping member and the cooperating surface of the locking member respectively have two first shoulders arranged in such a way that, l 'locking member being in the locking position, the shoulder of the locking member is in abutment against the shoulder of the clamping member and that the locking member is retained by gravity on the clamping member.
  • This arrangement essentially has the advantage of defining the position occupied by the locking member when it is in the locked position.
  • the second surface of the clamping member and the cooperating surface of the locking member respectively to have two second shoulders arranged in such a way that, when they cooperate, the locking member is freely engaged in the slot but not pressed in the locking position while preventing the clamping member from being released from the receiving member.
  • An intermediate position is thus defined for which, although the locking member is not yet in its locking position, said locking member however prevents the clamping member from disengaging from the receiving member. It is a waiting position which gives a certain degree of freedom between the mast and the element (cross member or the like) useful for example during assembly or disassembly operations.
  • the lower end of the locking member is arranged to cooperate with the first shoulder of the clamping member, the locking member then being released from the slot at least sufficient to release the clamping member vis-à-vis the receiving member and allow their release or mutual engagement.
  • the locking member is then in a position such that it is still or already in place in the assembly, but that it does not secure the clamping member to the receiving member: the clamping member can easily be placed on the receiving member or be released from it without any difficulty. It will be noted here that this possibility of "waiting" positioning of the locking member allows a single person to work successively on the two ends of a cross member and, therefore, to proceed, on its own, to assembly and disassembly of the cross member or the like.
  • the surface of the locking member cooperating with the second bearing surface has a shoulder arranged in such a way that, the locking member being in the locking position , the shoulder of the locking member is in abutment against the second rod-shaped bearing surface and that the locking member is retained by gravity on the clamping member. It can then advantageously be further provided that the lower end of the locking member is arranged to cooperate with the second bearing surface, the locking member then being released from the slot at least in a manner sufficient to release the clamping member vis-à-vis the receiving member and authorize their release.
  • the mounting of the cross member on the receiving member is carried out, thanks to the arrangements adopted in accordance with the invention, automatically, without requiring manipulation of parts.
  • the clamping member fitted to the end of the cross member is presented in front of the receiving member in the form of a cup; the locking member, which in practice remains permanently in the slot of the clamping member, then fell to the bottom of the slot under the action of gravity.
  • the clamping member is then placed on the cup, the edge of which pushes the locking member upwards in at the same time that the clamping member fits by simple gravity on the cup.
  • the locking member falls by simple gravity into the slot, until the semi-locking position (the two aforementioned second shoulders being in mutual cooperation) or lock (third embodiment).
  • the lower end of the locking member may have a transverse projection projecting laterally and in that at least one face inner side of the slot has a recess for receiving said projection positioned so that, when the finger is received in the recess, the locking member is in a partially released position for which the clamping member can be released of the receiving organ or engaged thereon.
  • the receiving member is a cup having approximately the general shape of a spherical zone open upwards.
  • any movement of the clamping member mounted and locked on the receiving member in particular of pivoting around the mast or else of rotation of the element on itself, around its axis, may provide that the wall of the receiving member has an inner face substantially in the form of a spherical zone and an outer face with a polygonal contour, in particular octagonal, this outer face being made up of curved facets substantially in the form of curvilinear isosceles trapezoids.
  • the wall of the receiving member has mutually substantially parallel inner and outer faces and substantially in the form of concentric spherical zones and that said outer face is provided with at least one substantially groove.
  • the outer face of the wall of the receiving member is provided with several grooves, in particular four or eight, regularly spaced around the periphery of said face, these grooves materializing as many mounting positions of elements, such as sleepers or the like on the receiving member.
  • the clamping member has an external bearing capable of being pressed against the mast .
  • FIG. 1 Another aspect of the invention also consists in providing a clamping member for the end of a scaffolding element, such as a cross-member or the like, intended to be assembled to a mast in a position approximately transverse thereto.
  • clamping member which, being arranged in accordance with the invention, is essentially cararterized in that it comprises a first clamping surface curved in an arc of a circle, to cooperate with an inner surface of a wall of a receiving member integral with the mast, and a second surface spaced from the first clamping surface, a slot passing through said clamping member to receive a locking member and opening out between its first and second surfaces mentioned above.
  • Yet another aspect of the invention consists in proposing an assembly consisting of a clamping member and a locking member which, being arranged according to the invention, is essentially characterized in that the clamping member is arranged as it has just been indicated and in that the locking member is movably engaged in the slot of the clamping member and has a generally curved shape with two mutually opposite parallel surfaces curved in an arc of a circle and concentric with the curved surface in an arc of the clamping member when it is in the locking position therein.
  • Yet another aspect of the invention consists in providing a scaffolding mast intended to support a scaffolding element such as a cross member or the like, said mast being provided with a receiving member in the form of a cup with general configuration in the zone spherical, open upwards, to receive a clamping member integral with the end of said element and constituted as indicated above, a scaffolding mast which, being arranged according to the invention, is essentially characterized in that the member receiver in the general form of a cup has an inner face substantially in the form of a spherical zone and an outer face having a polygonal contour, in particular an octagonal one, this outer face being made up of curved facets substantially in the form of curvilinear isosceles trapezoids; or alternatively, which is essentially characterized in that the generally cup-shaped receiving member has mutually substantially parallel inner and outer faces and substantially in the form of concentric spherical zones and in that said outer face is provided at least one groove, in particular four or eight grooves regularly spaced around the
  • a scaffolding mast 1 is provided with a receiving member 2 in the form of a cup open upwards, which is secured to it in any known way ( welding for example).
  • This cup 2 has the approximate general shape of a spherical zone, its wall 3 being, in vertical section, curved in an arc of a circle with a concavity turned towards the mast away from the mast from the bottom up.
  • the base of the cup 3 can be pierced with one or more orifices 6 for the evacuation of water.
  • the wall 3 has an inner face 4 which is substantially in the form of a spherical zone and an outer face 5 which, in top view , forms a polygonal outline; in practice, this polygonal contour has an even number of sides, commonly either four or eight sides (octagon) as shown.
  • this outer face 5 consists of curved facets 7 substantially in the shape of a curvilinear isosceles trapezoid.
  • the mast 1 fitted with a cup 2 of this configuration is shown in perspective in FIG. 7.
  • a scaffolding element 8 such as a cross-member or the like, is arranged (either integral with the cross-member, or else joined thereto - by welding or screwing for example -) a clamp 9 which is shown in the assembly position in FIG. 1 and in isolation in FIG. 5.
  • the clamping member 9 comprises, below, a clamping surface 10 curved in an arc of a circle of the same curvature as the inner face 4 of the wall 3 of the receiving member 2 in order to cooperate with the latter.
  • the front part 11 of the clamping member 9 constitutes a latching spout which is able to fit into the receiving member and to bear on it.
  • the clamping member 9 is taversed by a vertical slot 12 which, in its upper part, widens in the direction of the front (wall inclined towards the front 13) and which, in its lower part, is delimited by the clamping surface 10 towards the front and, towards the rear, by a second surface 14 distant from the previous one, which is intended to serve as support and guide for a locking member of which question below.
  • This second surface can have any shape compatible with its support and guiding function of the locking member and such that it does not hamper the free movement of the latter.
  • this second surface 14 is also curved in an arc of a circle and is parallel and concentric with the surface 10. In other words, in the mounting position shown in FIG. 1, this second surface 14 is substantially parallel and concentric with the outer face 5 of the wall 3 of the receiving member.
  • a locking member 15 of generally curved shape which has two opposite surfaces 16 and 17 mutually parallel and curved in an arc of a circle with a configuration complementary to those respective of the outer face 5 of the wall 3 of the the receiving member 2 and the second surface 14 of the clamping member 9.
  • the positioning of the locking member 15 in the locked position inside the clamping member 9, between the aforementioned faces 5 and 14, takes place without play, but also freely and without significant effort.
  • any force exerted on the clamping member 9 (or the cross member 8) in the upward direction, as well as any rotational force exerted on the clamping member 9 or the cross member 8 tending to rotate the latter on itself about its axis or else around the mast 1 can in no case cause the release of the clamping member 9 from the receiving member 2: this arrangement provides a reliable assembly, while moreover the constituent elements involved are of manufacture and cost substantially identical to those of the prior devices which did not offer the same degree of reliability.
  • the second surface 14 of the clamping member 9 and the corresponding surface 17 of the clamping member locking 15 have respectively, in their upper parts, two shoulders 18 and 19 which are able to cooperate with each other when the locking member is in the locking position ( Figure 1) so that it is retained in a defined position.
  • the locking member is arranged, in its upper part, so as to then be entirely erased in the slot 12 and completely release the upper part of the clamping member 9. This thus frees the entire distance between the two masts joined by the crosspiece 8, which facilitates for example the establishment of a deck.
  • the same surfaces 14 and 17 have two other shoulders 20 and 21 which are located in an intermediate location and which are able to cooperate with each other ( Figure 3) so that the locking member 15 is retained by gravity by the clamping member 9 in an intermediate position of positive unlocked engagement.
  • the locations of these shoulders 20 and 21 are such and the configuration (in particular the length) of the locking member 12 is such that, in this position where said member 12 rests freely by gravity on the clamping member 9, the release of the clamping member 9 from the receiving member 2 is not possible.
  • This position is therefore an intermediate waiting position which, during assembly or disassembly, gives the cross-member 8 relative freedom of angular movement relative to the mast 1 without, however, its total clearance being possible.
  • the locking member 15 has a flat 22 which is capable of resting on the abovementioned shoulder 18 of the surface 14 of the clamping member when the locking member is in the released position towards the top (see Figure 4).
  • the locking member then being released out of the corridor formed by the surfaces 14 and 5 facing each other, the clamping member 9 can be freely placed on the receiving member 2 or removed from it.
  • clamping member 9 To ensure the positioning and mutual blocking of the elements, provision is also made for the clamping member 9 to be pressed against the mast by an external bearing surface 25 which is disposed above the hooking spout 11, at the upper end of the clamping member.
  • the assembly of a cross member equipped as just indicated on the mast is carried out as follows.
  • the clamping member 9 fitted to the end of the cross member 8 is presented in front of the cup 2; the locking member 15 then fell to the bottom of the slot under the action of gravity.
  • the clamping member 9 is then placed on the cup 2, the edge of which pushes the locking member 15 upwards at the same time as the hooking spout 11 engages by simple gravity inside the cup 2
  • the locking member 15 falls by simple gravity into the slot until the standby or semi-locking position shown in FIG. 3.
  • the clamping member 9 does not can no longer disengage itself from the cup 2.
  • the disassembly is carried out, conversely, by tapping with a hammer on the lower end of the locking member 15, which brings it into the position of FIG. 2 from which it can easily be reassembled in the released position of Figure 3.
  • the cup 2 has two inner 4 and outer 5 faces which are substantially mutually parallel, in the form of substantially concentric spherical zones.
  • the outer face 5 is hollowed out at least one vertical groove 26; in practice four or eight grooves 26 are provided (as shown in FIG. 8) which are regularly distributed around the periphery of the cup and which materialize as many mounting positions for the elements 8 such as crosspieces (of the same name as the faces 7 of the configuration of the cup of FIG. 7).
  • the edge of the locking member with which the curved surface 16 is associated is partially engaged inside the groove 26.
  • the second surface 14 can have any shape compatible with its function. It can therefore not only be curved in an arc of a circle and be parallel and concentric with the clamping surface 10, but it can also be substantially planar and be tangent to a curved surface in an arc of parallel and concentric circle to the clamping surface 10, or alternatively be in the form of a simple rod or the like.
  • FIG. 10 represents such an embodiment.
  • the clamping member 9 has a slot 12 delimited laterally by two flanges 27 whose shape differs substantially that of the flanges of the embodiment shown in FIGS. 1 to 6.
  • Each flange 27 has a different width vertically on either side of a curvilinear shoulder 28: at the top, due to a greater thickness, the upper facing portions 29 define a constriction while at the bottom, due to a smaller thickness, the lower facing portions define a wider slot portion.
  • a transverse rod 31 extends between the two flanges facing the front part 11 of the attachment member.
  • the part of its surface facing said front part 11 constitutes the aforesaid second surface 14 for supporting and guiding the locking member 15.
  • the locking member 15 (which is shown here provided with a recess 32 in its upper part for its lightening) has approximately the same general shape as that of the embodiment of Figures 1 to 6, except that its edge intended to cooperate with the rod 31 is shaped so as to constitute a bearing heel 33 defining the aforementioned surface 17 which, here, is curvilinear and conforms to the shape of the contour of the rod 31 on which the member 15 rests in the locking position shown in Figure 10.
  • the part of the locking member 15 which borders the surface 17 also has an extra thickness 23 playing the same role as the aforementioned finger 23 and which abuts against the shoulder 28 when the locking member 15 is raised, in order to '' prevent it from coming out of the slot.
  • the lower end 22 of the locking member 15 is shaped to rest on the rod 31 when the locking member 15 is raised and to retain it in its upwardly released position (corresponding to that shown in FIG. 4).
  • the slot 12 is delimited by lateral flanges. It is therefore a single central slot capable of receiving a locking member 15 having a single body.
  • the same functions can be ensured and the same results can be obtained by providing a variant of the hooking device provided with a single central flange, defining two lateral slots situated on either side of said single flange, and of which the 'locking member is shaped as a rider adapted to overlap the central flange with its two legs engaged in the two respective side slots.
