Definitions

  • the invention relates to a device for anchoring an accessory or material on a roof and more particularly but not exclusively so as to be able to anchor therein a cable, a heddle, a ladder or an immediate attachment of safety equipment.
  • individual in order to carry out not only roofing work on a new roof but also repairs, alterations or maintenance operations.
  • service hook FR-A-1.280.836
  • U flat iron folded in
  • fixing means which is entirely located under the covering elements and remains permanently fixed to the rafter and a second part called “attachment member” which is separable so as not to assemble on the first until the intended use.
  • Means' for fastening comprises two flanges and two opposite trunnions, each carried by one of the two flanges which are in turn each applied on one side of the rafter and connected together by bolting.
  • the attachment member consists of a kind of service hook, the internal branch of which is terminated by an inverted "U" shoe, the branches of which are parallel to the faces of the rafter and each have a bayonet-shaped cutout for locking onto the spans of the trunnions.
  • this locking requires that the spacing of the bearing surfaces of the pins is the same as that of the branches of the shoe.
  • the fixing of the fixed part requires having on each side of the rafter a sufficient place and although this is at least equal to the additional thickness created by a flange and its journal.
  • the attachment member on which the anchoring takes place is separable, it may not be available to the person having access to the roof at the desired time and in any case it needs to be brought on the roof to be oriented and mounted correctly before it can itself receive the accessory or material that you want to anchor on the roof.
  • a result which the invention aims to obtain is an anchoring device which, while being split into two parts, namely a means of attachment to the rafter and a fastening member, so as not to be continuously exposed to the attacks of agents exterior, is nevertheless still available and can also be attached to any rafter even if only one of its faces is accessible.
  • the device 1 or 2 is fixed on a chevron 3 or 4 between two of the elements 5 and 6 or 7 and 8 such as the lath supporting the covering elements (not shown) such as tiles.
  • It mainly comprises a means 9 or 10 for fixing on the rafter and, combined with this fixing means, a member 11 or 12 for hooking the accessory or the material (not shown) such as a cable, a crosspiece or a ladder that we want to fix on the roof.
  • the attachment member 11, 12 is combined with the fixing means 9, 10, by a junction system 13 or 14 of any known type capable of making them inseparable while leaving them a degree sufficient freedom so that the fastening member can occupy two positions, one position where it is deployed so as to come partially projecting above the roof, said position of use, and another position where it is brought back to s '' eclipse under the covering elements, called the waiting or rest position.
  • the joining system 13 consists of a hinge pin 15 carried by the fixing means 9 and passing through a bore 16 of the fastening member 11.
  • the attachment member 11 and the fixing means have complementary abutment faces 17, 18 and 19, 20 limiting the angle of articulation of the attachment member and therefore precisely determining its extreme positions known as use or wait.
  • these abutment faces 17, 19 may be formed by the parts of the field of the said member located, with respect to the axis 15, one on the side opposite the end 21 where the hanging takes place and the other on the side of this end 21.
  • the fixing means it may be two sides of the same stud 22, for example fixed by a weld 23.
  • the system of junction 14 consists of a slide 24 with a longitudinal axis 25 not parallel, and preferably perpendicular, to that of the rafter, which slide 24 is carried by the fixing means and guides in translation the fastening member 12.
  • the fixing means 10 and this fastening member 12 have complementary abutment faces 27, 28 and 29, 30 limiting the translation of the fastening member and therefore precisely determining its extreme positions called use and waiting.
  • a finger generator 31, 32 for example welded to said member, and, for the fixing means 10, the ends 28, 30 of backstage.
  • the fastening member will also have, longitudinally spaced apart, several housings 33, 34, 35 capable of receiving a removable pin 36 making it possible to adjust the extent of the projection formed above the covering elements by the end 37 of the attachment member.
  • the fixing means 9 or 10 has a section, in an inverted "L", which is composed of a large plate 38 or 39 intended to be applied against the face of the chevron 3 or 4 and a rim 40 or 41 making an angle of ninety degrees with the plate and which is intended to be applied to the upper field of the rafter.
  • the plate After having been positioned on the rafter, for its fixing thereon, the plate is drilled with holes 42, 43 or 44, 45 crossed by fixing accessories such as screws or bolts (not shown).
  • the plate 38, 39 has on either side several additional orifices 46, 47, 48, 49 and 50, 51, 52, 53 drilled at different distances from the flange so, whatever the width of the rafter, to be able to find for the fixing a hole situated substantially at the height of the neutral fiber of the rafter.
  • junction system 54 between the hooking member 55 and the fixing means 56 consists of a hinge pin 57, which is carried by the means of attachment 56 and which is oriented substantially parallel to the direction of the rafter 58.
  • the fixing means consists for example of a plate 59 provided with orifices 60 for means for securing to a lateral face of the rafter 58.
  • Two wings 61, 62 are integral with the plate 59, and extend parallel to each other, perpendicular to the plate 59, and, preferably, substantially perpendicular to the upper face 73 of the rafter 58.
  • these wings extend towards the outside of the roof beyond the upper face 73 of the rafter 58, without however exceeding the level of the upper face of the battens 74, 75.
  • the wings 61, 62 each have one of the facing holes, which a hinge pin 57 crosses which constitutes the joining means 54.
  • the hooking member 55 consists of a dish 64 of generally rectangular shape.
  • This plate is articulated in rotation around the axis 57, for example by means of a tube 65 which the axis 57 crosses which is integral with one of the large faces of the plate 64 in its central zone, and which extends substantially perpendicular to the largest dimension of the dish.
  • the hooking member 55 can occupy a position which is shown in FIGS. 7 and 8, in which its upper part 66 projects above the roof and its lower part 67 bears against the plate 59 of the fixing means.
  • the wings 61 and 62 then constitute lateral stops wedging the lower part 67 of the plate 64.
  • locking means act in this position at the lower part 67 of the plate 64.
  • Any suitable locking means is suitable, and for example, a pin oriented horizontally, vertically or obliquely.
  • the figures represent an axis 68 integral with the plate 59 to which it is perpendicular which passes through the lower part 67 of the plate 64 and which, at its free end, is in turn traversed transversely by a removable pin 69 .
  • the hooking member 55 is entirely retracted below the level of the upper face of the battens 74, 75.
  • the dish 64 is shown in this position in phantom 70 in FIG. 8.
  • the articulation axis 55 being offset relative to the bearing face of the plate 59 of the fixing means and relative to the upper face 66 of the rafter 58, this ensures that, in its position waiting, the plate 64 is housed between the axis 57 and the upper face of the rafter 58 to be fully retracted under the level of the upper face of the battens 74, 75 and that in the position of use it is housed between the axis 57 and the abutment face 74 of the plate 59.
  • the upper part 65 of the dish 64 has any suitable means for attaching equipment such as an orifice 71 which can, for example, receive a mooring tube for a ladder or a console, and smaller orifices 72, for receiving for example individual safety equipment.
  • an orifice 71 which can, for example, receive a mooring tube for a ladder or a console, and smaller orifices 72, for receiving for example individual safety equipment.
