Definitions

  • the invention relates to an adjustment system, a method of manufacturing such an adjustment system and an adjustment method using such an adjustment system.
  • harnesses which have adjustment straps cooperating with an adjustment system in the form of an adjustment buckle. Adjustment straps are used to adjust the circumference of a thigh circumference and/or to adjust the length of a suspender.
  • adjustment buckle with a ring and a strap that passes through the ring.
  • the ring is partially closed off by a rod mounted to move relative to the ring.
  • the strap goes through the hole in the ring for the first time, then it goes around the rod to come back inside the ring. Once the strap is under tension, the rod moves in the direction of one end of the ring, which makes it possible to block the strap between the rod and the ring.
  • Different configurations of adjustment buckles are known and in particular those disclosed in the documents EP0614626 , FR2996732 , EP2946682 , US9433260 , US2007/0187445 , US1697833 , US2563809 And US2807852 .
  • the adjustment system must be easy to use. It must in particular allow easy sliding of the strap to allow precise adjustment of the latter to the desired length. It must also maintain the adjustment applied to the strap when the latter is under tension.
  • Adjustment systems equipped with a blocking cap are known.
  • the cover is mounted so as to rotate between a first position which allows the strap to slide and a second position which locks the strap in the chosen position.
  • the cover presses on the strap to prevent any movement of the strap. It is then necessary to deactivate the blocking cover to adjust the strap.
  • Such a technical solution is cumbersome and impractical in the field of pruning because branches can actuate the blocking cap. This technical solution involves a large number of parts which limits its interest.
  • the document US 2004/0169411 discloses the installation of a blocker made of textile material of the VELCRO ® type.
  • the blocker opens to allow access to the adjustment buckle and therefore adjustment of the shoulder strap. When the blocker closes, the buckle is no longer accessible and prevents adjustment.
  • This solution is not practical because it requires the installation of an additional and bulky element around the adjustment buckle.
  • it is common to work with gloves so that the ascender must be able to be used with gloves such as those used in work at height which requires having an ascender bulky. Such a technical solution is not possible.
  • An object of the invention consists in overcoming these drawbacks, and more particularly in providing an adjustment system which ensures better maintenance of the position chosen for a strap in the adjustment system while remaining simple to use and without penalizing the holding of the power setting.
  • the adjustment system is remarkable in that it comprises a tongue at least partially obstructing the first through-hole in the first direction, the tongue being arranged at a distance from the rod to define a passage space for the first strap between the rod and the tongue.
  • the tab is made of a flexible material.
  • the tab is made of polymer material.
  • the tongue is fixed exclusively to the ring.
  • the tab is removably installed on the ring.
  • the adjustment system comprises an additional ring mounted to move relative to the ring, the rod forming part of the additional ring.
  • the tongue is attached exclusively to the additional ring.
  • the tongue is removably installed on the additional ring.
  • the invention also relates to a method of manufacturing a carabiner which is easier to implement than the methods of the prior art.
  • a permanently closed textile loop surrounds part of the ring and passes through the first through hole.
  • the tongue is fixedly mounted on the textile loop.
  • the strap passes through the first through hole and the second through hole.
  • a separation distance between the rod and the tongue in the first direction is greater than the thickness of the strap in the first direction.
  • the invention also relates to a harness for which the adjustments of its straps are better maintained.
  • a tie-in harness comprising an adjustment system according to any one of the preceding configurations in which the adjustment system is configured to adjust the circumference of a circumference of the thigh.
  • a tie-in harness comprising an adjustment system according to any one of the preceding configurations in which the adjustment system is configured to adjust the length of a strap.
  • Another subject of the invention is a method of manufacturing an adjustment buckle which is easy to implement and which allows better holding of the adjustment of the first strap.
  • the adjustment system 1 which is configured to adjust the length of a first strap 2.
  • the adjustment system 1 belongs to a system for adjusting a tie-in harness which is intended for work at height and/or activities in which the user is suspended by means of his harness.
  • the harness may be a mountaineering harness, a canyoning or caving harness as shown in figure 10 . It can also be a harness for pruning work or for other acrobatic work, for example working on a wind turbine.
  • the adjustment system can be a thigh circumference adjustment system or a shoulder strap adjustment system.
  • the first strap 2 forms all or part of a thigh circumference or the first strap 2 can form all or part of a shoulder strap.
  • the inventors have observed that in many conditions, when a user adjusts his harness, for example his leg loops and walks to reach the desired location, he applies opposing forces to the adjustment system. Different forces are applied to the adjustment system with variable directions and intensities and induce a misadjustment of the adjustment system.
  • the adjustment system being configured to have an easy sliding of the strap in order to facilitate obtaining a precise adjustment, this also facilitates the disruption of the leg loops during the walking phases. Disadjustment of the shoulder straps is also observed with other movements. It is therefore proposed to modify the adjustment system so as to improve the operation of the adjustment system and better maintain the adjustment of the strap when the strap is not under tension.
  • the adjustment system 1 comprises a ring 3 which defines a first through hole.
  • the first through hole passes through the ring 3 in a first direction A.
  • the ring 3 can extend in a first plane as shown in section on the figures 1, 2 , 4 And 8 .
  • Ring 3 is then a planar ring.
  • ring 3 is slightly bent.
  • the curvature of the ring 3 can be substantially uniform from one end to the other of the ring 3 or else localized at one or more places of the ring 3 as has already been used in configurations of the art prior.
  • the adjustment system 1 has a rod 4 mounted to move relative to the ring 3.
  • the rod 4 partially obstructs the ring 3 in the first direction A so as to divide the first through hole into a second through hole 3a and a third through hole 3b.
  • the third through hole 3b is separated from the second through hole 3a by the rod 4 when the adjustment system 1 is observed in the first direction A.
  • the first strap 2 passes through the ring 3 passing through one of the second through hole 3a and the second through hole 3b.
  • the first strap 2 goes around the rod 4 to cross, again, the ring 3 passing through the other of the second through hole 3a and the second through hole 3b.
  • the rod 4 is mounted so as to move towards or away from a wall of the ring 3.
  • the first strap 2 is put under tension, it pulls on the rod 4 which approaches the wall of the ring 3 which has the effect of blocking the first strap 2 and therefore of maintaining the adjustment of the first strap 2 under load.
  • a strand of the first strap 2 is wedged between the ring 3 and the rod 4.
  • the inventors have observed that when walking, the various movements of the legs tend to induce opposing forces on the strands of the strap on either side of the upper.
  • a movement of the leg has the effect of moving the upper strand of the first strap 2 which induces a force which tends to form a strap loop projecting from the adjustment system.
  • the portion of the first strap 2 which covers the upper 4 deviates slightly from the upper 4.
  • the first strap 2 defines an increasingly large loop.
  • the other strand of the first strap remains stuck against the leg of the user.
  • the other strand of the first strap 2 tends to pull on the first strap 2 which ends the disruption of the first strap 2.
  • the tongue 5 at least partially obstructs the first through hole in the first direction A.
  • the tongue 5 is arranged at a distance from the rod 4 to define a passage space for the first strap 2 between the rod 4 and the tongue 4.
  • the tongue 5 covers the rod 4 in the first direction A.
  • the tab 5 is arranged at a distance from the rod 4 so as not to modify the operation of the rod 4 during the tightening and loosening phases of the first strap 2 in the system Clamping. Tab 5 is not resting on rod 4.
  • the tongue 5 is arranged at a distance from the upper in the first direction A which is greater than the thickness of the first strap 2 in the first direction A. In this way, when the first strap 2 goes around the upper 4 by bearing on the latter, there remains at least one empty zone between the first strap 2 and the tongue 5.
  • the tongue 5 prevents the formation of a loop of the first strap 2 which is too large and therefore reduces or even prevents the loss of adjustment. By reducing the height of the buckle, the unwanted elongation of the first strap 2 is reduced.
  • the tab 5 is made of a flexible material.
  • a flexible material makes it possible to have a deformation of the tongue 5 which facilitates the installation of the first strap 2 in the adjustment system 1.
  • the use of a flexible material allows the tongue 5 to deform which avoids forming a hook detrimental to the safety of the user.
  • the tongue 5 is made of polymer material. The distal portion of the tab 5 deforms which allows the user to access the first strap 2, for example to remove the first strap or on the contrary to facilitate the installation of the first strap 2.
  • the tongue 5 is fixed exclusively to the ring 3.
  • FIGS 1 to 7 Such an embodiment is illustrated to figures 1 to 7 .
  • These figures also illustrate a preferred embodiment in which the tongue 5 is removably mounted with respect to the ring 3.
  • the use of a removably mounted tongue 5 makes it possible to improve an existing adjustment system without having to change the ring 3.
  • the tongue 5 is configured to rest on the user.
  • the tab 5 is configured to extend under the underside of the ring 3 so as to be wedged between the ring and the user.
  • FIG. 3 illustrates a particular configuration of tongue 5 which has an open cavity 6 intended to allow the insertion then the embedding of a portion of the ring 3.
  • the tongue 5 has a support zone 7 which is intended to bear against the outer faces of the ring 3 and thus ensure good support on the ring 3 and precisely define the separation distance between the tongue 3 and the rod 4 with respect to the thickness of the first strap 2.
  • the ring 3 is wedged against the support area 7 in the open cavity 6.
  • THE figures 5, 6 And 7 illustrate another configuration of the tab 5 mounted on the ring 3.
  • the figures 5, 6 And 7 illustrate an embodiment where the tongue 5 is removably mounted with respect to the ring 3.
  • the figures 4 to 7 illustrate an embodiment in which the tongue 5 is mounted to move along the ring 3.
  • the tongue 5 is movable along the longitudinal axis of the adjustment system which is also the longitudinal axis of the first strap 2.
  • FIG 6 illustrates a tab 5 provided with two grooves 8 inside which the ring 3 can slide.

  • the rod 4 forms part of the additional ring 10.
  • the figures 8 and 9 illustrate an adjustment system 1 which comprises a ring and an additional ring 10.
  • the tongue 5 is fixed exclusively to the additional ring 10. In another embodiment, the tongue 5 is fixed to the ring 3. The tongue 5 does not modify the relative movement of the ring additional 10 with respect to the ring 3. In yet another embodiment illustrated in figures 8 and 9 , the tab 5 is fixed to a fixing member 11 which performs the fixing between the ring 3 and the additional ring 10.
  • the fixing member 11 is a strap ring which secures the connection between the ring 3 and the additional ring 10 and which allows relative movement between the ring 3 and the additional ring 10.
  • the strap ring can be a ring formed at the end of the first strap 2 or a ring formed at one end of a second strap.
  • the tongue 5 is fixed to the strap ring by sewing, but any other fixing means is possible.
  • the fastening member 11 can be formed by a second strap 12 which is shaped like a loop by means of one or more seams 13.
  • the tab 5 defines an annular fixing member with a through hole allowing the passage of the ring 3 and the additional ring 10 so as to form the fixing member 11.
  • a closed textile loop which permanently secures the ring 3 and the additional ring 10.
  • the closed textile loop surrounds part of the ring and passes through the first through hole.
  • the tongue 5 is fixedly mounted on the closed textile loop. The deformation of the closed textile loop allows a slight displacement of the obstruction zone 9 with respect to the upper 4.

  • the foot of the tab 5 is arranged to bear against the user and against the internal face of the ring 3 which makes it possible to limit the movement of the tab 5 and thus define the separation distance between the tab 5 and the rod 4.
  • the first strap 2 passes through the second through-hole 1a and the third through-hole 1b.
  • the first strap 2 goes around the rod 4.
  • a first strand of the first strap 2 is intended to be wedged between the second strand of the first strap 2 and the ring 3.
  • the traction applied to the strand of the first strap 2 to achieve locking the first strap against the ring has the effect of moving the obstruction zone 9 and the first strap 2 away.
  • the tongue 5 can be installed on an already existing adjustment system 1 which makes it possible to improve the adjustment system 1 by making it less sensitive to phenomena of sliding of the first strap 2 when the latter is not under tension.
