Definitions

  • the present invention relates to the field of retaining devices, in particular hook retaining devices.
  • Hook closure systems are well known and used in numerous fields of application, leading in fact to the production of multiple forms of hooks or more generally to multiple forms of retaining elements intended to cooperate mutually or with complementary elements such as curls.
  • a recurring problem with such products concerns the restraining force applied, taking into account in particular the greatly reduced dimensions of the hooks and the associated manufacturing constraints.
  • the present presentation thus aims to respond to these various problems by proposing a retaining device whose geometry is simpler, more easily reproducible and could in particular be obtained from a more broad spectrum of raw materials in view of shortages of certain raw materials on a global scale.
  • the present invention thus proposes a retaining device, for example to produce a self-gripping connection comprising:
  • the head fits into a second circle C2 with center 02 and diameter D2, said second circle being the smallest circle comprising the head, which second circle C2 being tangent to one end of the head in the longitudinal direction and/or the transverse direction such that the maximum dimension of the head passing through the center 02 of the circle C2 and extending in the longitudinal direction and/or the transverse direction is less than 80% of the diameter D2 of the second circle C2.
  • the second circle C2 is included in the first circle C1.
  • the first circle C1 having a diameter D1 the distance between 01 and 02 is less than or equal to 50% of the diameter D1 of the first circle C1, in particular less than 30%, less than 25%, less than 20%, less than 15%, or less than 10%, and optionally, the distance between 01 and 02 is greater than or equal to 0% of the diameter D1 of the first circle C1, or greater than 0%, or greater than 1%, or greater than 4%.
  • Such a structure implies that the base of the rod and the head are centered or almost centered relative to each other, and therefore that the rod of the retaining element is straight or substantially straight. This makes it possible to improve the mechanical strength of the retaining element, and to limit its deformations under the effect of shearing during its interactions with fibers of a non-woven.
  • the second circle C2 is included in the first circle C1 that at least 95% of the surface of the circle C2 is included in the first circle C1, in particular 98%, in particular 100%.
  • the distance between 01 and 02 is less than or equal to 50% of the diameter D2 of the second circle C2, in particular less than 30%, less than 25%, less than 20%, less than 15%, less at 12%, or less than 10% and optionally, the distance between 01 and 02 is greater than or equal to 0% of the diameter D2 of the second circle C2, or greater than 0%, or greater than 1%, or greater than 4%.
  • Such a structure also implies that the base of the rod and the head are centered or almost centered relative to each other, and therefore that the rod of the retaining element is straight or substantially straight. This makes it possible to improve the mechanical strength of the retaining element, and to limit its deformations under the effect of shearing during its interactions with fibers of a non-woven.
  • the distance between 01 and 02 is less than or equal to 100 pm, in particular less than or equal to 75 pm, 50 pm or 30 pm.
  • the upper end of the rod fits into a third circle C3, said circle C3 being included in the second circle C2.
  • a non-woven material is secured to the underside of the base.
  • the ratio of the diameter D2 of the circle C2 and the diameter D1 of the circle C1 is between 0.3 and 0.95 or more precisely between 0.5 and 0.9. So the widest dimension of the head is smaller than the width of the lower end of the shank.
  • the lower end or foot of the rod is thus reinforced, and the shearing or peeling forces applied by a non-woven are distributed to limit the deformation of the rod at its lower end.
  • the retaining elements have a hooking height Ha of between 30 micrometers and 120 micrometers, more particularly between 30 micrometers and 70 micrometers, even more particularly between 40 micrometers and 60 micrometers.
  • the retaining elements have a hooking dimension Da, greater than 40 micrometers, in particular greater than 60 micrometers, and/or less than 120 micrometers, in particular less than 100 micrometers.
  • the hooking dimension Da corresponds to the maximum direction between the upper end 32 of the rod 30 and an external radial end of the head 40, measured in a radial direction relative to a central axis of the rod 30.
  • the retaining elements have at least one hooking dimension Da and the radial direction is the machine direction and/or the transverse direction.

  • the ratio of the hooking height Ha and the height Ht of the rod is between 0.05 and 0.4, in particular between 0.05 and 0.3, more particularly between 0. 1 and 0.25.
