Definitions

  • This invention is in the sector of fall protection safety systems intended for buildings.
  • this invention relates to a fall protection hooking device, as a support for safety lines or a fall protection hooking element, the fall protection system comprising said device and a fall protection safety method.
  • the basic aim of this invention is to provide a fall protection hooking device, a fall protection system comprising said device and a fall protection safety method that can overcome one or more of the above-mentioned disadvantages.
  • one of the aims of this invention is to provide a fall protection hooking device and a related fall protection system which can withstand the sudden stress caused by a fall by an operator connected to them, without said fall causing abrupt breaks in the structure of the device and/or partial or total detachment of the device from the fixed structure of the building to which it is fastened, and at the same time characterised by a high level of effectiveness in the action of absorbing the sudden stress deriving from the operator fall.
  • a further possible aim of this invention is to provide a fall protection system which is strong enough for working in any operating conditions, that is to say, which can remain fastened to the building structure following a sudden stress deriving from a fall by an operator hooked to it, can withstand the fatigue cycles caused by its own thermal expansion and that of the building structure and can preserve its mechanical features unchanged as time passes.
  • a further possible aim of this invention is to provide a fall protection hooking device, system and safety method which are more reliable and/or guarantee an operator anchored to the device, working on the roof of a building, greater safety.
  • One of the possible aims of this invention according to one or more of its various aspects is to provide a fall protection hooking device and system which are characterised by reduced thickness and/or dimensions and/or reduced use of material for their production.
  • a fall protection hooking device as a fall protection hooking element or safety line support, a fall protection system and a fall protection safety method, with the technical features described in one or more of the appended claims, each of which taken alone (without the relative dependent claims) or in any combination with the other claims, as well as according to the following aspects and/or example embodiments, variously combined, also with the aforesaid claims.
  • the invention relates to a fall protection hooking device having a substantially plate-like conformation and provided with a first end and a second end, structurally opposite to said first end, intended to be stiffly fixed to an anchoring element so as to be made mutually integral, and provided with a hooking portion structurally interposed between said first and second end and structured for the hooking of a fall protection cable, the hooking device developing with structural continuity from the first to the second end passing through the hooking portion, the hooking device presenting a first series of folding lines, interposed between said first end and said hooking portion, and a second series of folding lines, interposed between the second end and said hooking portion, each pair of adjacent folding lines in each series delimiting a respective sub-portion of the hooking device so as to define a series of sub-portions each lying in a plane which is oblique with respect to the lying plane of the adjacent sub-portions, the hooking device being structured for deforming, in use, at least at said folding lines due to a tensile force applied
  • the Applicant believes that the combination of the above-mentioned technical features, in particular the presence of the first and second series of folding lines at which, in use, the device deforms due to a tensile force applied to the hooking portion structurally interposed between the two ends intended to be stiffly fixed to an anchoring element so as to be made mutually integral, so that the hooking portion changes its position with respect to the ends, allows a hooking device to be obtained which is able to effectively dampen the wrenching action in the event of an operator fall and can absorb the stress deriving from said fall (preventing said stresses from discharging on the fasteners attached to the building structure or to the roof) and at the same time characterised by a simple, rational structure which is easy and inexpensive to produce, for example by means of suitable cuts and bends of a single part having a plate-like conformation (for example a portion of sheet metal).
  • the Applicant also believes that the above-mentioned technical features advantageously allow stable and balanced fixing to a building structure, by means of the anchoring element, which is strong enough to withstand typical strains for the fall protection device, and at the same time can absorb in an original way the stress produced by a fall.
  • said absorption occurs through deformation of the structure of the device, said deformation typically comprising (at least partial) compression (of the folding lines) of the portion of the device located between the hooking portion and the end (first or second) on the side of the tensile force (or at least one component of it) and stretching (of the folding lines) of the portion of the device between the hooking portion and the end (second or first) on the side opposite to the above-mentioned tensile force.
  • That method of deformation of the structure may allow the device to effectively absorb stresses which are ideally directed along any axis and in any direction, combining in any condition the compression of some folding lines and stretching of others.
  • the anchoring element is intended to be stiffly fixed to a building structure and, in use, is interposed between the device and the building structure. Equivalently, the first and second ends can be fixed directly to the building structure.
  • the deformation of the device remains elastic at least up to a value of said tensile force less than or equal to 2 kN, preferably less than or equal to 2.5 kN. In that way the device effectively absorbs the small stresses deriving from normal use by an operator (and/or from thermal cycles), without compromising the potential for absorbing the stresses in the event of a fall.
  • said deformation becomes plastic (permanent) at a value of said tensile force greater than 2 kN, preferably greater than 3 kN, and even more preferably greater than 4 kN. In that way, the device effectively absorbs the sudden stresses caused by an operator fall.
  • plastic (permanent) deformation refers to inelastic deformation.
  • the device folded along the above-mentioned folding lines into a series of sub-portions, forms an element with a predetermined level of plastic yielding and able to limit or cancel out the sudden nature of a fall stress.
  • the Applicant has found, through testing, that the energy developed in the fall is used to plastically deform the anchoring body, at the same time reducing the wrenching action applied to the operator and the maximum load that the device must support, thus allowing the device to be made smaller than prior art devices, as well as making smaller parts for fixing the device to the building structure.
  • the hooking device comprises a first portion of the device interposed between said first end and said hooking portion and a second portion of the device interposed between said second end and said hooking portion.
  • the first and second portions are identical to each other and symmetrical with respect to a middle plane of symmetry passing through the hooking portion.
  • the first portion of the device and the second portion of the device extend parallel and adjacent to each other. According to one aspect, the first and second portions lie geometrically on the same side of the hooking portion.
  • the first portion of the device and the second portion of the device extend on the same line. According to one aspect, the first and second portions lie geometrically on opposite sides of the hooking portion.
  • the first and second ends are provided with a respective end face, preferably flat, which in use is intended to be fixed directly to the building structure or, in a preferred alternative, to the anchoring element.
  • the end faces of the first and second ends which are preferably identical, lie in the same lying plane.
  • the folding lines of the first and/or second series of folding lines lie in respective planes which are transversal (preferably at a right angle) to said lying plane.
  • the device is structured in such a way that, in use, it responds with a greater deformation, and so with greater energy absorption, in particular for a tensile force which has a main component parallel with the lying plane.
  • the folding lines of the first and/or second series of folding lines lie in respective planes which are substantially parallel with said lying plane.
  • the device is structured in such a way that, in use, it responds with a greater deformation, and so with greater energy absorption, in particular for a tensile force which has a main component that is transversal (preferably at a right angle) to the lying plane.
  • the first and second series of folding lines each comprise at least three folding lines, preferably at least five, by way of example at least six.
  • the first and second series of sub-portions define a respective series of smallest angles between each pair of respective adjacent sub-portions.
  • each of the smallest angles is on a face of the respective first or second portion of the device opposite to the face on which the adjacent smallest angles are.
  • the smallest angle defined between two adjacent sub-portions is constant.
  • the smallest angle defined between at least two adjacent sub-portions is less than or equal to 135°, preferably less than or equal to 110°, even more preferably equal to 90°.
  • the device has a constant thickness, preferably between 1 mm and 10 mm.
  • the fall protection hooking device has an overall dimension, along an axis at a right angle to the lying plane, less than, preferably less than half of, even more preferably less than one quarter of, the overall dimension of the fall protection device along an axis passing through the two end faces. That limits the height extension of the fall protection device from the fixed structure to which it will be fixed. That is advantageous because it allows a reduction in the overall dimensions of the device and limits, depending on the application, the vertical distance between the hooking portion and the first and second ends, that is to say, the lever arm of the tensile force applied to the hooking portion.
  • the invention relates to a fall protection system comprising:
  • the Applicant believes that the plate-like conformation of the anchoring element guarantees stable, secure and easy fixing on building structures (for example a roof) already provided with a cover, and can be obtained in an easy, inexpensive way.

  • the anchoring element is structured for fixing to a rib of a standing seam profile sheet.
