Definitions
- the present invention relates, on the one hand, to an anchor for to be fixed in a supporting structure of wall or floor type, and other on the other hand, to an anchoring device equipped with such anchors.
- Such equipment is usually composed of a cable or a pair of parallel and substantially horizontal cables, called supports belay, crossing intermediate anchors fixed from a sufficiently strong carrier structure.
- End anchors feature means for allowing the ends of the supports to be attached belay.
- Each user wears a harness that is connected by a lanyard to a slider moving on the belay supports.
- Intermediate anchors are designed in such a way that the slider can cross them in order to move belay devices from one end to the other.
- the end anchors are provided with limit stop devices.
- Such anchors can be each made using, on the one hand, a plate intended to be fixed in the carrier structure, and secondly, of a liaison body supporting the belay supports and rotatably mounted around the plate.
- the present invention aims to overcome the disadvantages previously mentioned, and concerns for this purpose an anchor comprising, on the one hand, a plate intended to be fixed in a supporting structure of wall type or floor, and secondly, a connecting member attached to said platen and provided to support at least one horizontal flexible belay support, said member linkage pivotable about a substantially parallel axis to the plane in which said platinum is contained during the fall of a user connected to the belay support, characterized in that it comprises at least one damping element attached to the connecting member and adapted to deform in contact with the plate during the pivoting of said connecting member.
- an anchor makes it possible to prevent the forces generated by the fall of the user does not reach, on the mounting face of the plate, the limit elastic deformation of the carrier structure. Indeed, during his fall, the user exerts efforts on the belay through the lanyard and the slider. These belay devices are driven downwards and cause the pivoting of the connecting member of the less an anchor close to the user.
- Each damping element of this anchor which deforms in contact with its turntable and thus absorbs a part induced efforts, ultimately allows to minimize the residual efforts exerted by the anchor on the supporting structure.
- each damping element comprises at least one suitable damping lug to deform by sliding against the platen during the pivoting of the liaison body. It should be understood, however, that a variant entering in the scope of the invention may reside in the use of a rigid leg integral with the connecting member and able to cause, during the pivoting of the connecting member, the deformation of a malleable coating deposited on the platinum.
- an interstice is initially provided between each damping tab and platinum.
- each damping lug has a decreasing section towards its free end intended to come to the platinum contact during the fall of the user.
- the liaison body is bound by the platinum through at least one shear pin designed for to break when the user falls.
- the liaison body is bound by the platinum through at least one shear pin designed for to break when the user falls.
- each cushioning element consists of a separate part provided with minus one shear pin engaged in an orifice presented by the platinum.
- the connecting member is decomposed, of a part, in a first part attached to the plate and able to rotate around the axis parallel to the plane in which said platen is contained, and secondly, in a second part directly connected to each support belay and fit to pivot about an axis substantially perpendicular to each support belay.
- the second part attached to each belay support being free to rotate around the first part, it follows that the deformation experienced by each belay support at the point of attachment with the linker is greatly minimized.
- an end anchor intended to be fixed in a supporting structure of wall or floor type, the axis around which pivots the connecting member during the fall of the user is substantially perpendicular to each belay support.
- an intermediate anchor intended to be fixed in a supporting structure of wall or floor type, the axis around which pivots the connecting member during the fall of the user is substantially parallel to each belay support.
- the present invention also relates to a device anchor equipped with at least one horizontal flexible belay support, characterized in that it comprises at least two end anchors according to the invention.
- a device anchor equipped with at least one horizontal flexible belay support, characterized in that it comprises at least two end anchors according to the invention.
- an anchoring device also comprises less an intermediate anchor according to the invention.
- FIGS. 1 to 4 An anchoring device 1 according to the invention is shown in FIGS. 1 to 4. More precisely, this anchoring device 1 comprises, on the one hand, two end anchors 2 and an intermediate anchor 3 fixed in a support structure 4 of floor type, and secondly, two supports belay 5 made in the form of two parallel parallel cables. A The user is connected to said cables 5 via a lanyard and a slider (not shown).
- the anchors 2, 3 are made from a plate 6 to which is attached a connecting member 7 respectively mobile in rotation about a axis ⁇ , ⁇ 'parallel to the plane in which said platen 6 is contained.
- the plate 6 is provided with several perforations 9 allowing its fixing in the supporting structure 4 by screwing or bolting for example, and, as can be seen in particular in Figure 5, two side cheeks 10 each having a hole 11 of larger diameter and an orifice 12 of smaller diameter.
- the connecting member 7 is broken down, on the one hand, into a first stirrup-shaped portion 13 intended to be articulated around the axis ⁇ or ⁇ ', this stirrup 13 having two branches 14 each having one end lower part provided with two orifices 15, 16 respectively identical to the holes 11, 12 of the lateral cheeks 10, and secondly, in a second part 17 equipped with two tubular guides traversed by the cables 5 and able to pivot around an axis ⁇ "substantially perpendicular to these.
- each branch 14 of the stirrup 13 is arranged against the inner face of the branch 14 and consists of a one-piece piece having a central portion framed by two legs 7.
- the material in which the element is made damping element 18 is chosen so as to have a lower hardness than that of the material in which the plate 6 is made.
- Both legs of damping 19 are in opposite directions and have a section decreasing towards their free end, and the central part is provided, on the one hand, with a threaded transverse lug inserted into the orifices 11, 15 of larger diameter, and secondly, a shear pin 21 transverse inserted in the orifices 12, 16 of smaller diameter.
- a nut (not shown) can then be attached to the threaded stud 20 to prevent any separation between the stirrup 13 and the plate 6.
- the pin of shear 21 can initially bind the stirrup 13 and the plate 6 so rigid, but is designed to break when the user falls. Moreover, it must be noticed that each damping element 18 is fixed so an interstice is initially provided between each damping tab 19 and the plate 6.
- an end anchor 2 and an intermediate anchor 3 lies in the fact that the axis ⁇ of the end anchor 2 is substantially perpendicular to the cables 5, whereas the axis ⁇ 'of the intermediate anchor 3 is substantially parallel to said cables 5.
- each damping element 18 remains integral with the stirrup 13. Therefore, under the effect of gravity, as well the stirrup 13 that the damping elements 18 are caused to pivot about 90 ° around the axis ⁇ '. In doing so, one of the two legs of damping 19 of each damping element 18 is caused to deform by sliding against platinum 6, which has the effect of absorbing progressively part of the forces applied to the anchoring device 1. The pivoting of the stirrup 13 and depreciation elements 18 ceases when the stirrup 13 abuts against the supporting structure 4 or against a ledge (not shown) of platinum 6. Finally, the residual efforts that exerted on the support structure 4 at the level of the intermediate anchor 3 are shear forces that are not likely to damage said supporting structure 4.
- each connecting member 7 is free to rotate about the axis ⁇ ". deformation experienced by each cable 5 at the level of the two tubular guides of the second part 17 is greatly minimized.
- FIGS. 10 to 12 Another variant embodiment of an anchor 101 according to the invention is shown in FIGS. 10 to 12.
- Such an anchor 101 comprises a plate 102 to which can be attached a movable connecting member 103 around an axis ⁇ parallel to the plane in which said plate 102 is contained.
- the connecting member 103 is broken down, on the one hand, into a first part under the shape of a branch 104 hinged about the axis ⁇ , and secondly, in one second portion 105 having a tubular guide traversed by a cable 106 and adapted to pivot about an axis ⁇ "substantially perpendicular to said cable 106.
- the attachment of the connecting member 103 to the plate 102 is not realized using a separate room.
- the depreciation component 18 anchors 2, 3 is here integrated in the branch 104 of the anchor 101. More specifically, the branch 104 has a lower end provided with two damping lugs 108, a threaded transverse lug 109 and a shear pin 110 respectively comparable to the legs damping member 19, pin 20 and shear pin 21 of the member damping 18 anchors 2, 3.
- the attachment of the organ link 103 to the plate 102 is finally achieved by insertion of the pin 109 and of the shear pin 110 in two sections 111, 112 tubular integral with the plate 102.
- an anchor according to the invention can be very operate well without having a shear pin. Indeed, in case of fall of the user, the damping legs then enter immediately in action to reduce the efforts generated. In other cases, for example when the user exercises little effort on the supports during his travels, the liaison rotate, but only at a slight angle, until one of the two legs damping comes into abutment against the plate.
