Description

technical field

[0001] The invention relates to a device for fixing to an anchor point and to a method for releasing such a device. Previous technique

[0002] In many rope access activities, the rope access technician works far above the ground, and it can be difficult to move to reach the ground or their anchor point. To avoid unnecessary movement, the technician equips themselves with the necessary safety gear to ensure the proper execution of their work.

[0003] In exceptional circumstances, a rope access technician may injure themselves, which tends to complicate their movements and / or reduce their speed. In the most dangerous situations, the technician is unable to move. To ensure their safety against the most common injuries, the technician is equipped with a first aid kit that must be readily accessible in case of an accident. Ideally, the first aid kit should be attached to the harness so that the technician doesn't have to move along the rope to reach it after an accident.

[0004] There is a compromise to be found between the ability of the first aid kit to remain attached to the rope harness when the harness rubs against walls or is caught on branches and the ease of detachment without compromising its safety.

[0005] US patent 8,713,764 discloses a connector structure designed to attach an object to a support platform. The attachment mechanism consists of multiple straps that define a plurality of loops. The object to be attached also has a loop, and a tongue ending in a hook inserts into the loops on the object and the loops on the support to secure the object to the support. The hook is equipped with a locking element that has a locked position preventing the tongue from moving and an unlocked position allowing the tongue to move.

[0006] Document FR3015207 discloses a military intervention harness equipped with a thigh strap, shoulder straps and a belt which are equipped with attachment straps in the form of loops. Object of the invention

[0007] An object of the invention consists of providing a fastening device which can be easily attached to an anchor point and whose detachment from the anchor point is easy while reducing the risk of loss of the fastening device and preferably which allows one-handed release while reducing the risk of loss of the fastening device once released.

[0008] This result is achieved by means of a fastening device designed to attach to an anchor point, the fastening device comprising: a blocker configured to attach to the anchor point, the blocker defining an open position and a closed position, the closed position prohibiting the extraction of the anchor point from the blocker and the open position permitting the extraction of the anchor point from the blocker, the blocker having a support defining a hole and a rigid tab mounted movable relative to the hole, the rigid tab being in the hole in the closed position and out of the hole in the open position, in which, in the closed position, the anchor point is intended to be located between the rigid tab and the support; a latch defining a locked state and an unlocked state, the latch having a first part and a second part, the first part attaching to the second part or releasing itself from the second part to define said locked and unlocked states respectively; wherein the first piece is hooked to the rigid tab; wherein, in the locked position, the first piece limits movement of the rigid tab to prevent relative movement between the rigid tab and the support out of the closed position to maintain the lock in the closed position; wherein the second piece is connected to the rigid tab or fixed to the support; wherein, in the unlocked position, the first piece permits movement of the rigid tab out of the hole; wherein each of the first and second pieces is fixed to the support when the lock is in the unlocked position.

[0009] According to one aspect of the invention, the support is connected to the rigid tab by a flexible element when the lock is in the unlocked position.

[0010] Advantageously, the flexible element terminates at one end by the first part and at a second end by the second part. In the locked position, the flexible element forms a flexible loop surrounding the support.

[0011] In a particular configuration, the attachment device to an anchor point includes an adjustment loop configured to adjust a length of the flexible element and tighten the flexible element around the support in the locked position.

[0012] In an advantageous development, in the locked position, the rigid tab is positioned between the support and the flexible loop.

[0013] Preferably, the anchor point is intended to be positioned between a mounting surface of the support and the rigid tongue. The anchoring surface defines an edge. In the closed position, the rigid tongue extends from the hole to the edge.

[0014] In one embodiment, the hole is a through hole. In the closed position, the rigid tab passes through the hole and emerges beyond the hole.

[0015] In an advantageous design, the anchoring point is intended to be positioned between a mounting wall of the support and the rigid tongue. The anchoring wall defines an additional hole, with the rigid tongue passing through this additional hole in the closed position.

[0016] Preferably, the support defines an unremovable opening envelope of the hole.

[0017] In another advantageous development, the support has a plate and an openable envelope removably attached to the plate, the openable envelope being removable from the plate when the blocker is in the open position and inremovable from the plate when the blocker is in the closed position.

[0018] Preferably, the device for attaching equipment to an anchor point includes a rope harness, the anchor point being a strap attached to a belt or thigh loop of the rope harness.

[0019] Advantageously, the openable envelope is a first aid kit.

[0020] Preferably, the rigid tongue has an angled portion, the edge resting on the angled portion when the flexible loop is in the closed position.

[0021] It is particularly advantageous to provide that the support defines an additional hole, the rigid tab penetrating the additional hole when the rigid tab is in the first position, the hole and the additional hole being aligned along a sliding direction of the rigid tab between the closed position and the open position.

[0022] The invention also relates to a method for releasing a fastening device that is simple to implement and preferably can be done with one hand.

[0023] This result is achieved through a release process that includes the following steps: provide a fastening device according to any of the preceding configurations, the fastening device being attached to an anchor point; open the lock by acting on the first piece to separate the first piece and the second piece, the grip being made on the first piece; pull on the first piece to move the rigid tab from the closed position to the open position and separate the fastening device and the anchor point.

Description of the implementation methods

[0025] THE figures 1 to 10illustrate different embodiments of a fastening device 1 which is configured to be removably attached to an anchor point 2 and a rope harness 3 which has a wire element intended to form the anchor point 2. The wire element can be a webbing, a rope, a braid, a fabric, a textile element or any other suitable material.

[0026] In acrobatic activities, the rope harness 3 may be leaning against walls, branches or other protruding elements which may apply a force on the fixing device 1. In order to prevent accidental detachment of the fixing device 1 from the anchor point 2, the fixing device 1 includes a blocker 4 which attaches to the anchor point 2 and a lock 5 which allows or prevents the change of state of the blocker 4.

[0027] We are looking for a fixing device 1 which ensures a solid and effective fixing with the anchor point 2 while being easy to open when necessary.

[0028] The fastening device 1 includes a locking mechanism 4 configured to attach to the anchor point 2. The locking mechanism 4 defines an open and a closed position. The closed position prevents the anchor point 2 from being removed from the locking mechanism 4. The open position allows the anchor point 2 to be removed from the locking mechanism 4. The locking mechanism 4 has a support 6 defining a hole 7 and a rigid tab 8 that is movable relative to the hole 7. In the closed position, the rigid tab 8 is inside the hole 7. In the open position, the rigid tab 8 is outside the hole 7. In the closed position, the anchor point 2 is intended to be located between the rigid tab 8 and the support 6.

[0029] The fastening device 1 forms a ring which is openable and of which the blocker 4 forms at least the movable part.

[0030] The rigid tab 8 is mounted movable relative to the support 6 in order to slide in or out of the hole 7. Advantageously, the sliding is a translation.

[0031] Blocker 4 has a closed state, as illustrated in the diagram. figures 1, 2 And 5 à 9 and an open state illustrated in figures 3 and 4 .

[0032] The fastening device 1 also includes a latch 5 defining a locked state and an unlocked state. To open the locking device 4, the latch 5 must first be moved from the locked position to the unlocked position. The latch 5 generally comprises two parts that cooperate to define a position where the two parts are fixedly mounted to each other and a position where the two parts are free to move relative to each other.

[0033] The lock 5 has a first part 9 that attaches to a second part 10 or detaches from the second part 10 to define the locked and unlocked states, respectively. The first part 9 is connected to the rigid tab 8. The second part 10 is connected to the rigid tab 8 or attached to the support 6. In the locked position, the lock 5 prevents relative movement between the rigid tab 8 and the support 6 from the closed position, thus keeping the blocker 4 in the closed position, i.e., keeping the rigid tab 8 in the hole 7.

[0034] The lock 5 in the unlocked position allows the blocker 4 to move from the closed position to the open position by allowing the rigid tab 8 to move out of the hole 7. Each of the first part 9 and the second part 10 is fixed to the support 6 when the lock 5 is in the unlocked position.

[0035] When a rope access technician is injured, they often use one hand to treat the injury. Consequently, they only have one hand left to release and handle a first aid kit. Therefore, it is advantageous to provide a fastening device 1 associated with a first aid kit that allows for one-handed release and reduces the risk of losing the fastening device 1 once it has been detached from the anchor point 2. Once the fastening device 1 is detached from the anchor point 2, the first part 9 is fixed to the support 6, the second part is fixed to the support 6, and the rigid tab 8 is fixed to the support 6.

[0036] Following the injury, the user will attempt to reach the unlocked position, possibly using their only functioning hand. The user will therefore operate one or the other of the two parts. It is thus important that each of the two parts be securely attached to the support 6 so that, upon release, the user holding one of the two parts of the lock 5 is connected to the fastening device 1.

[0037] If the user has only one functional hand, it is advantageous for the release mechanism of the fastening device 1 to be simple. A sliding movement of the rigid tab 8 appears easy to achieve. However, for the same reasons as before, it is preferable for the user to maintain contact with the support 6 while unlocking the lock 5 and opening the blocker 4.

[0038] In a particularly advantageous embodiment, illustrated in figures 1 to 8To facilitate the application of a force which opens the blocker 4, a flexible element 11 is arranged between the rigid tab 8 and the first part 9. Thus, when the user holds the first part 9, the movement of the first part 9 to apply a force on the rigid tab 8 is accompanied by a deformation of the flexible element 11 to facilitate the opening of the blocker 4.

[0039] In an alternative illustrated implementation to the figure 9 , the first part 9 is connected directly to the rigid tab 8.

[0040] The first part 9 can be connected to the support 6 by means of an additional flexible element, for example the same flexible element which connects the first part 9 to the rigid tab 8 and preferably which extends the flexible element 11 beyond the connection or even the fixing between the flexible element 11 and the rigid tab 8.

[0041] It is particularly advantageous for the support 6 to define an opening envelope; the opening envelope can be fixed to the support 6. One or more of the walls of the opening envelope advantageously define the external walls of the support 6. Alternatively, the support 6 is equipped with a plate 6' and an opening envelope that is removably attached to the plate 6'. The plate 6' can be a standard plate, and different types of opening envelopes can be attached to the plate 6' to adapt the volume of the opening envelope to the requirements. The opening envelopes can differ in their dimensions, opening mechanisms, or other characteristics. Thus, a user who already has their opening envelope can attach it to a plate 6'. It is particularly advantageous for the opening envelope to be fixed to the plate 6' when the stopper 4 is in the closed position.More preferably, the openable envelope is fixed to the plate 6' by fastening means which are actuated independently of the blocker 4 in order to reduce the risk of loss of the openable envelope when the blocker 4 is in the open position. figure 8 This illustrates an embodiment of a support 6 equipped with a plate 6' that is removable from the opening cover, but such an embodiment can be implemented for the other illustrated embodiments. Advantageously, the plate and the opening cover are removable when the blocker 4 is in the openable position, and more preferably by using other fastening elements.

[0042] It is particularly advantageous that the first part 9 and / or the second part 10 be integral with the openable envelope without regard to the fixing which exists between the openable envelope and the plate 6'.

[0043] In an advantageous embodiment, when the lock 5 is in the unlocked position, the support 6 is connected to the rigid tab 8 by a flexible element 11. In the unlocked position, the flexible element 11 secures the rigid tab 8 to the support 6, which in turn secures the first part 9 to the support 6.

[0044] In a particularly advantageous embodiment, the flexible element 11 terminates at one end by the first part 9 and at a second end by the second part 10, in the locked position. The flexible element 11 forms a flexible loop that surrounds the support 6. The closer the length of the flexible element 11 approaches the perimeter of the support 6, the more difficult it becomes for the rigid tab 8 to move, thus complicating or preventing the opening of the stopper 4. Preferably, the flexible element 11 is associated with an adjustment loop 12 configured to adjust the effective length of the flexible element 11 between the first part 9 and the second part 10, thereby allowing it to adapt to different or more or less filled opening envelopes.This embodiment is particularly advantageous when the openable envelope can be separated from the 6' plate and / or when the openable envelope has one or more flexible walls allowing deformation.

[0045] The larger the rigid tab 8, the more difficult it is to move it out of the closed position when the flexible loop is closed. Advantageously, the anchor point 2 is designed to be positioned between a retaining wall of the support 6 and the rigid tab 8. The retaining wall defines an edge. In the closed position, the rigid tab 8 extends from the hole 7 to the edge. The closer the shape of the flexible loop is to the shape of the support 6, the more difficult it is to move the rigid tab 8. When the flexible loop surrounds the support 6 in contact with it, unintentional opening of the locking mechanism 4 becomes very difficult, even without applying significant clamping force. Securing the closed position is all the more important as the length of the rigid tab 8 increases.

[0046] The use of a flexible loop is particularly advantageous because it allows for better adaptation to supports possibly associated with openable envelopes of various shapes.

[0047] There Figure 10 This illustrates one embodiment of a rope harness 3. The rope harness 3 comprises a waist belt 3a and a pair of leg loops 3b. The rope harness 3 has one or more wire elements that define one or more anchor points 2.

[0048] As illustrated in figures 1 to 9 The support 6 is preferably in the form of an opening envelope, for example, a pouch, and more preferably a first aid kit. For example, the support 6 contains first aid supplies, advantageously at least a bandage, an antiseptic, and possibly adhesive tape. The support 6 then constitutes a first aid kit.

[0049] It is conceivable that the opening envelope may contain user-installable equipment other than items found in a first aid kit. The opening envelope may be opened, for example, by means of a zipper or any other means allowing access to its contents. The opening envelope may have any shape, preferably a parallelepiped, and more preferably a rectangular parallelepiped.

[0050] When the lock 5 is in the locked position, the movement of the rigid tab 8 becomes increasingly difficult as the length of the flexible element 11 approaches the perimeter of the support 6 along a cross-sectional plane where the support 6 forms a ring around the support 6. It is therefore advantageous to have a flexible element 11 whose length-to-perimeter ratio of the support 6 is between 1 and 1.5, preferably between 1 and 1.25, and even more preferably between 1 and 1.1. The flexible element 11 can be equipped with an adjustment loop 12 configured to adjust its length. The closer the length of the flexible element 11 is to the perimeter of the support 6, the greater the friction at the edges of the support 6 covered by the flexible element 11.More generally, the fastening device may include means for adjusting the length of the flexible element 11 to tighten the flexible element 11 around the support 6 in the locked position.

[0051] As illustrated in figures 1 to 4 It is advantageous to use a lock 5 in the form of a clip that can preferably be operated with one or two fingers. The first part 9 and the second part 10 preferably have distinct shapes, allowing the user to differentiate, by touch, between the first part 9 and the second part 10. Another lock 5 is possible, for example, with a loop and a hook or a hooking material.

[0052] To form the hole 7, it is advantageous for the support 6 to include a wire element 13 that projects to form a hoop receiving the rigid tab 8 in the closed position. The wire element 13 can be a flexible material, such as a rope, strap, braid, or fabric. Using a wire element 13 facilitates the deformation of the hoop when the rigid tab 8 is in the open position, thus making it easier to detach the fastening device 1 from the anchor point 2.

[0053] In the particular embodiment illustrated in figures 1 to 4 The support 6 has an additional hole 7' and, even more advantageously, an additional hoop formed by a wire element 13 such as the one described above. The use of two hoops makes it possible to constrain the position of the anchor point 2 and to better maintain the position of the rigid tab 8.

[0054] Preferably, and as illustrated in figures 1, 2 And 5 à 8 The rigid tab 8 is bent. This makes the rigid tab 8 more rigid and / or makes it more difficult to apply the forces aimed at moving the rigid tab 8 towards the release position when the flexible element 11 forms a closed flexible loop.

[0055] The rigid tongue 8 will have more difficulty twisting than the flexible element 11 to follow the change in orientation of the walls represented by the edge. Furthermore, the more rigid the rigid tongue 8, the more difficult the translation will be for a given force applied to the flexible element 11. For example, the rigid tongue 8 can be formed from a layer of wood, metal, composite material, or polymer material.

[0056] Preferably, the rigid tab 8 is positioned between the flexible loop and the support 6, so as to limit the possibilities of movement of the rigid tab 8 and introduce friction.

[0057] In a particular embodiment, the movable tab 8 is arranged to move only in translation within the slide defined by the hole 7 or the holes between the closed and open positions. Movement that is only possible in translation makes accidental actuation of the movable tab 8 more difficult.

[0058] By using a flexible element 11 which is attached to the rigid tab 8, a tensile force applied to the flexible element 11 causes the rigid tab 8 to move between the closed and open positions. Depending on the configuration, one end of the rigid tab 8 may be fixed to a portion of the wire element 13, or one end of the rigid tab 8 may be able to slide relative to a portion of the wire element 13 only under certain conditions, specifically up to a threshold value. In this way, when the user holds the first part 9 to open the lock 5, the tensile force applied to the flexible element 11 by pulling on the first part 9 moves the rigid tab 8 to open the lock 4. By continuing to pull on the first part 9, the support 6 is moved relative to the anchor point 2 to release the fastening device 1.

[0059] As the rigid tab 8 is attached to the flexible element 11 and that the flexible element 11 is attached to the support 6, the action performed by the user to open the blocker 4 ensures that at the moment of separation between the fixing device 1 and the anchor point 2, the user will hold an element attached to the fixing device 1. The risk of loss of the fixing device 1 is very low or even zero.

[0060] In order to act on the lock 5 and the blocker 4 by engaging the first part 9, different configurations are possible. figures 1 to 5These figures illustrate an embodiment where the support 6 is surrounded by the flexible loop when the latch 5 is in the locked position. The first part 9 and the second part 10 are mounted to move relative to the support 6 in the unlocked position. The closer the perimeter of the flexible loop is to the perimeter of the support, the more difficult it is to move the flexible loop, which in turn complicates the movement of the rigid tab 8. The deeper the rigid tab 8 is inserted into the hole 7 or extends beyond the hole 7, the more difficult it is to leave the closed position. This is particularly true when the rigid tab 8 extends from the hole 7 to an edge of the support 6. The second part 10 can be used to prevent separation between the support 6 and the flexible element 11, for example, by having a width greater than the width of an opening through which the flexible element 11 passes.

[0061] There figure 6This illustrates another embodiment where the second part 10 is fixedly mounted to the support 6. The flexible element 11 extends on one side to the first part 9 and on the other side to a fastening area designed to be attached to the support 6. The fastening area and the first part 9 limit the movement of the flexible element 11, which in turn limits the movement of the rigid tab 8 to prevent the locking mechanism 4 from opening. Once the first part 9 is released from the second part 10, i.e., the lock 5 is unlocked, a force applied to the first part 9 puts stress on the fastening area, which gives way, allowing the rigid tab 8 to move. The fastening area can be used to prevent separation between the support 6 and the flexible element 11.

[0062] There figure 7 illustrates another embodiment which corresponds to an alternative embodiment of the figure 6where the second end of the flexible element 11 is attached to the first part 9 or the second part 10, while the second part 10 is fixedly mounted to the support 6. When the first part 9 is removed from the second part 10, the second end of the flexible element 11 becomes free to move. A force applied to the first part 9 to move the rigid tab 8 out of the hole 7 is not impeded by the second end of the flexible element 11. The connection between the second end and the first part 9 and / or the second part 10 may be a one-time connection, indicating that the support 6 has been used.

[0063] There figure 8This illustrates another embodiment where the first part 9 and / or the second part 10 act directly on the rigid tab 8 to prevent or allow its movement. When the first part 9 separates from the second part 10, the locking of the rigid tab 8 is released. When the first part 9 leaves the second part 10, the second end of the flexible element 11 becomes free to move. A force applied to the first part 9 to move the rigid tab 8 out of the hole 7 is not prevented by the second end of the flexible element 11. The locking can be achieved by a wire element, for example, a rope or a strap.

[0064] There figure 9This illustrates yet another alternative where the rigid tongue 8 extends continuously from hole 7 to the first piece 9. Securing the first piece 9 to the second piece 10 significantly limits the movement of the rigid tongue 8. This embodiment is less advantageous than the previous one because using a rigid tongue 8 that extends over several faces of the support 6 makes it more difficult to move the rigid tongue 8 to achieve sliding from the closed to the open position. Such a movement can be very difficult to perform with one hand, while suspended in a harness 3, and with an injury. Using a flexible element 11 between the first piece 9 and the rigid tongue 8 allows for better control of the force that causes the rigid tongue 8 to slide. Furthermore, it is advantageous to have a rigid tongue 8 with only one bend.More advantageously, the rigid tongue 8 has a first part and a second part separated by a bend, the first part being longer than the second part. The first part is designed to fit into the hole 7, as illustrated in the figures. figures 1, 2 , 5, 6 , 7 and 8 The flexible element 11 extends at least from the attachment wall to another wall of the support 6, bypassing the edge. The flexible element 11 limits the movement of the rigid tab 8 relative to the hole 7. The flexible element 11 passes through the rigid tab 8, thus imposing the direction of movement relative to the support 6 and the anchor point. The tighter the flexible element is relative to the support 6, the more difficult it is to move the rigid tab 8. The rigid tab 8 is preferably L-shaped. The flexible element 11 bypasses the edge, thus locking the angled portion.
