Definitions

  • these devices essentially comprise a cable fixed at its two ends and stretched substantially parallel to the circulation path.
  • a hooking member of the carabiner type can slide, connected by a strap or the like, to the user.
  • the carabiner, initially uncoupled, is hooked beyond the support member, it suffices to unhook the other carabiner and proceed in the same way for crossing the member.
  • the object of the invention is to remedy these drawbacks in a simple and effective manner.
  • the problem which the invention proposes to solve is to create a safety device which is located, not at the level of the hooking means on the cable, but directly at the level of the particular design of the intermediate support members, thus avoiding , the use of relatively complicated designs.
  • each intermediate support member has a determined profile capable of ensuring both the support of the cable and the passage of the carabiner without uncoupling with said cable.
  • the problem posed is resolved in that the profile (1a) (1b) (1c) of each support member (1) is determined to allow the passage of the carabiner without uncoupling as it travels along the cable (C), by subjecting said carabiner to different angular movements, in combination with said profile.
  • the particular profile of the latter comprises a central support and retaining part extended laterally by a curved filiform element constituting an open loop.
  • the central support and retaining part is in the form of a profiled nose formed transversely in overflow from a plate arranged to ensure the fixing of the assembly of the support member.
  • the profiled nose is formed very substantially perpendicularly to the fixing plate.
  • the curved filiform element constituting an open loop is arranged symmetrically to the profiled nose.
  • the profiled nose has, transversely, a curved profile, while its lateral sides are arranged angularly by being connected by a wide radius of curvature, said sides being extended by the curved threadlike element.
  • the filiform element is doubly curved in a lateral plane and in a transverse plane to constitute, very substantially, a helical profile, arranged symmetrically at the nose, constituting in combination with the lateral sides, a continuous guide path. for the passage of the carabiner, so as to subject it to the various successive movements, relative to the cable, very substantially describing a sinusoid.
  • the problem posed of being able to move the carabiner by subjecting it to various successive angular movements relative to the cable, by very substantially describing a sinusoid, is solved in that the various support members are fixed so that the cable is positioned in the center of the path guide defined by the filiform element and the nose.
  • Figures 6 to 10 show, by different perspective views, the passage of the carabiner in combination with the profile of the support member and the deformation of the cable.
  • the safety device is essentially established from a cable (C) fixed at each of its ends, by means of any suitable element capable of keeping the cable in tension. Given the length of the cable, the latter preferably cooperates at regular intervals with intermediate support members designated as a whole, by (1).
  • This cable is intended to ensure the restraint of the person having to move on the path (A).
  • the support members provide support for the cable in the event of a fall of the operator who is connected to the cable by a strap or the like, having, at the end, a carabiner (M) which can slide along the cable as and when its displacement.
  • each intermediate support member (1) has a determined profile capable of ensuring both the support of the cable (C), in particular in the event of a fall, and the passage of the carabiner (M) without uncoupling of the latter. with said cable.
  • each support member (1) is determined to allow, continuously, the passage of the carabiner, as and measuring its displacement along the cable, by subjecting said carabiner to different movements of angular orientation in combination with said profile.
  • each support member (1) consists of a central support and retaining part (1a) extended laterally, by a filiform element (1b) curved to form an open loop (1c).
  • the central part (1a) is in the form of a profiled nose, formed transversely, projecting from a plate (1d) arranged to ensure the fixing of the whole of the support member (1). Note that this fixing can be done by any means, for example, by bolting, welding ...
  • the profiled nose (1a) has, transversely, a curved profile determined to ensure the retention of the cable in the event of a fall.
  • the nose (1a) is formed very substantially perpendicularly to the fixing plate (1d) ( Figure 5).
  • the lateral sides (1a1) and (1a3) of the nose are angularly arranged to be connected by a wide radius of curvature (1 a2), said sides being combined with the curved filiform element (1b), forming an open loop.
  • the filiform element (1b) is doubly curved in a lateral plane and in a transverse plane to constitute, very substantially, a helical profile.
  • This helical profile (1b) is arranged symmetrically to the nose (1a) constituting, in combination with the lateral sides (1a1) (1a3) a continuous guide path for the passage of the carabiner (M) by subjecting it to different successive angular movements, relative to the cable, so as to describe very substantially, a sinusoid ( Figures 2 and 4).
  • the different support members (1) are fixed so that the cable (C) is positioned in the center of the guide path delimited by the filiform element (1b) and the nose (1a).
  • Figure 6 shows the carabiner (M) attached to the cable and before the passage of the support member (1).
  • the carabiner For the passage of the carabiner, the latter is oriented angularly (Figure 7), to allow the introduction of said carabiner into the opening of the loop (1c).
  • the carabiner is then positioned, still being coupled to the cable and after a new angular movement, between the loop and the profiled lateral edge (1a1) of the nose (Figure. 8).
  • the carabiner is angularly folded down so that it passes over the curved profile (1a2) of the nose ( Figure 9).
  • the carabiner can then be placed beyond the other lateral side (1a3) of the nose ( Figure 10) then, after a new angular orientation, cross the other loop.
