Definitions

  • the present invention relates to a security device anti-fall intended in particular for operators operating in height or on inclined planes, for example on ladders, pylons, chimneys, roofs, facades or in wells, and allowing ascent or descent of these operators or loads along a flexible link, for example a cable, rope or strap.
  • a security device anti-fall intended in particular for operators operating in height or on inclined planes, for example on ladders, pylons, chimneys, roofs, facades or in wells, and allowing ascent or descent of these operators or loads along a flexible link, for example a cable, rope or strap.
  • Security devices can be classified fall protection in two main categories according to their use with fixed or current attachment point.
  • a first category relates to devices intended to be hung on a fixed point in height and connected to a operator or to a load via a cable mobile leaving the device.
  • This device has many disadvantages, in particular a risk of breaking or damaging the cable due to the direct connection with the drum, a unsuitable for use with attachment point current and a very important weight.
  • this cable is returned to the device by a return spring, which deprives the operator of any use of the device.
  • attachment point refers to devices intended for sliding or roll back and forth along a cable, the operator being connected to the chassis of the device, for example by through a harness.
  • this device is not very reliable or even dangerous. Because if in his fall the operator clings to the device, which is frequent in such a case, braking cannot not occur because the notched jaw is no longer actuated by the operator's fall.
  • this device only works in one sense, which can be dangerous if the device is installed in the wrong direction on the cable.
  • the present invention therefore aims to avoid disadvantages mentioned above and to propose a two-way anti-fall safety, which is extremely reliable from a security point of view, which prevents damage to the cable, which is adaptable for a fixed or common attachment point use, which is easily unlockable and light in weight, and which is simple and inexpensive to manufacture.
  • the present invention relates to a anti-fall safety device comprising at least one flange on the internal face of which is mounted madly a pulley with circular groove for receiving a link flexible, blocking means being formed respectively on the facing faces of said pulley and said flange to selectively allow blocking in relative rotation of said pulley and of said flange when the centrifugal force generated by the rotation of the pulley exceeds a value of predetermined threshold and the free rotation of the pulley in the otherwise, characterized in that said apparatus comprises in addition two screeds joined and spaced from each other, on the internal faces and opposite which are journalled said flange and pulley through of a common axis of rotation and in that each flange is able to move between at least two inclined positions active, in which at least two stop members, which are provided at the periphery respectively of said flange and said yokes, cooperate to brake and immobilize, by for example by pinching or tightening, said flexible link, and a so-called central
  • the blocking of the pulley and braking of the flexible link is therefore effected by different means, but which cooperate with each other.
  • the flanges serve as a movable stop allowing brake the flexible link in the event of a fall operator or load.
  • each flange is biased towards said rest position by elastic return means, such as connecting springs said yokes to said flange, which facilitates the unlock the device after a fall and prevent all inadvertent blocking of the device.
  • the apparatus of the invention advantageously comprises two flanges integral and spaced from each other, for example by spacers, to receive between their internal faces and opposite said pulley, the flanges being movable in rotation with respect to the yokes.

  • one of the two stop members is mobile and the other fixed on their respective support, the organ movable stop bearing on the fixed stop member during moving each flange to the active position, for example via a cam profile or in the form of a flexible bond, which causes the displacement of the movable stop member and the pinching of the link section flexible to be braked between the pulley groove and said movable stop member.
  • the apparatus may also include means on said yokes and said flange to limit displacement of the flange in the active position and in particular to avoid deterioration and shearing of the flexible link, these means limiters which can possibly be arranged on the organs abovementioned stop.
  • guide means such as rollers, small pulleys or fixed spacers are fitted between the yokes of the device in the vicinity of the outlet of the two opposite sections of the flexible link and arranged substantially on either side of the pulley to orient the flexible link in a substantially straight direction or vertical in the case of use with hooking point current, and to keep said flexible link in the device.
  • guide means are mounted between the yokes of the device at the exit of the two opposite sections of flexible link and arranged on the same side of the pulley and in the vicinity of each others to give the flexible link a form substantially U-shaped in the case of point use fixed attachment.
  • the device includes an indexing system allowing adjust the position of said stop members and / or said guide means, so as to allow the use of the same device in the case of a current attachment point or fixed.
  • the stop members and / or the guide means belong to a range of shape and size modules which can be adapted on the same device through the aforementioned indexing system.
  • the apparatus of the invention may optionally include a mobile counterweight at one end of the flexible link and comprising a braking means for maintaining the counterweight in position on the flexible link in the absence of external forced solicitation.
  • the apparatus may include at least one scraper member mounted on the device in the vicinity of the outlet of at least one of the two opposite flexible link sections, so that clean the latter, this scraper member being consisting for example of a rigid helical and coaxial wire with said flexible link section to be cleaned.

  • the pulley 4 has a circular groove 8 for the reception of the rope 3.
  • the section of the circular groove 8 can be semi-circular, U-shaped or have any shape suitable for flexible link she should receive.

  • a spring 12 is connected at its two ends respectively on the flanges 5 and on the yokes 6.
  • the flanges 5 cannot therefore rotate freely around axis 7 because they are biased towards a central position called rest (shown in Figure 1) by a force of elastic return generated by this spring 12.

  • FIG. 4 There is shown in Figure 4 a particular example locking means consisting of two weights forming ratchet 16 mounted with free rotation on said pins eccentrics 15 which project perpendicularly from said faces of the pulley 4.
  • the two pawls 16 are elastically connected by two springs 17.
  • Notches 18 are formed circularly in the faces next to the flanges 5 so that the imaginary circle 19 which passes through the top of said notches 18 circumscribes the pawls 16 when they are retracted towards the center 7 of the pulley under the action of the spring return 17.
  • the imaginary circle 19 is centered on the axis 7 of the pulley 4.
  • the notches 18 are formed at the periphery of a recess 20 formed in the facing faces of said flanges 5, said recess 20 housing the pawls 16.
  • the movable pawls 16 are able to move between a so-called retracted position (shown in FIG. 4) and a so-called locking position in which the pawls 16 abut against the notches 18 via of a 16a of their ends.
  • the pawls 16 move away from this retracted position when the centrifugal force generated by the rotation of the pulley 4 exceeds a threshold value predetermined function of the stiffness of the springs 17.
