Description

Title of the invention: DEVICE FOR ATTACHING TO AN ANCHOR POINT AND METHOD FOR RELEASING SUCH A DEVICE 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 acrobatic 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 rope access technician equips themselves with the necessary equipment for their safety and for the proper execution of their work.

[0003] In exceptional cases, a rope access technician may be injured, which tends to complicate their movements and / or reduce their speed. In the most dangerous situations, the rope access technician is unable to move. To ensure their safety against the most common injuries, the rope access 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 rope harness so that the technician does not have to move along the rope to reach the kit after an accident.

[0004] A compromise must 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. Object of the invention

[0005] 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.

[0006] 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 preventing the anchor point from being extracted from the blocker and the open position allowing the anchor point from being extracted 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 tongue and the support; - a lock defining a locked state and an unlocked state, the lock 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 respectively said locked and unlocked states; in which the first piece is attached to the rigid tab; in which, in the locked position, the first part limits a movement of the rigid tab to prevent relative movement between the rigid tab and the support out of the closed position to maintain the blocker in the closed position; in which the second part is connected to the rigid tab or fixed to the support; in which, in the unlocked position, the first piece allows the rigid tab to move out of the hole; in which each of the first piece and the second piece is fixed to the support when the lock is in the unlocked position.

[0007] 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.

[0008] Advantageously, the flexible element terminates at a first termination by the first part and at a second termination by the second part. In the locked position, the flexible element forms a flexible loop surrounding the support.

[0009] 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.

[0010] In an advantageous development, in the locked position, the rigid tab is arranged between the support and the flexible loop.

[0011] Preferably, the anchoring point is intended to be located between a mounting wall of the support and the rigid tongue. The anchoring wall defines an edge. In the closed position, the rigid tongue extends from the hole to the edge.

[0012] According to one embodiment, the hole is a through hole. In the closed position, the rigid tab passes through the hole and emerges beyond the hole.

[0013] In an advantageous development, the anchoring point is intended to be disposed between a mounting wall of the support and the rigid tongue. The anchoring wall defines an additional hole, the rigid tongue passing through the additional hole in the closed position.

[0014] Preferably, the support defines an unremovable opening envelope of the hole.

[0015] In another advantageous development, the support has a plate and a 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 non-removable from the plate when the blocker is in the closed position.

[0016] Preferably, the device for attaching equipment to an anchor point comprises a rope harness, the anchor point being a strap attached to a belt or a thigh loop of the rope harness.

[0017] Advantageously, the openable envelope is a first aid kit.

[0018] Preferably, the rigid tongue has an angled portion, the edge being in contact with the angled portion when the flexible loop is in the closed position.

[0019] It is particularly advantageous to provide that the support defines an additional hole, the rigid tab penetrating into the additional hole when the rigid tab is in the first position, the hole and the additional hole being aligned according to a sliding direction of the rigid tab between the closed position and the open position.

[0020] The invention also relates to a method for releasing a fastening device which is simple to carry out and preferably with one hand.

[0021] This result is to be achieved by means of a release process which comprises the following steps: - provide a fastening device according to any of the previous 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 detach the fixing device and the anchor point.

[0033] Figures 1 to 10 illustrate 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 strap, a rope, a braid, a fabric, a textile element or any other suitable material.

[0034] In acrobatic activities, the rope harness 3 may be supported against walls, branches, or other protruding elements that can exert force on the attachment device. To prevent accidental detachment of the attachment device 1 from the anchor point 2, the attachment device 1 includes a rope clamp 4 that attaches to the anchor point 2 and a locking mechanism 5 that allows or prevents the rope clamp 4 from changing its state.

[0035] We are looking for a fastening device 1 which ensures a solid and effective fastening with the anchor point 2 while being easy to open when necessary.

[0036] The fastening device 1 includes a locking device 4 configured to attach to the anchor point 2. The locking device 4 defines an open position and a closed position. The closed position prevents the anchor point 2 from being removed from the locking device 4. The open position allows the anchor point 2 to be removed from the locking device 4. The locking device 4 has a support 6 defining a hole 7 and a rigid tab 8 mounted movable relative to hole 7. In the closed position, the rigid tab 8 is in hole 7. In the open position, the rigid tab 8 is out of hole 7. In the closed position, the anchor point 2 is intended to be located between the rigid tab 8 and the support 6.

[0037] The fastening device 1 forms a ring which is openable and of which the blocker 4 forms at least the movable part.

[0038] 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.

[0039] The blocker 4 has a closed state illustrated in figures 1, 2 and 5 to 9 and an open state illustrated in figures 3 and 4.

[0040] 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 with each other 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.

[0041] 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 10. In the locked position, the lock 5 prevents relative movement between the rigid tab 8 and the support 10 from the closed position, thus maintaining the stopper 4 in the closed position, i.e., maintaining the rigid tab 8 in the hole 7.

[0042] 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.

[0043] When a rope access technician is injured, they often use one hand to treat the injury. Consequently, they are left with only one hand to release and handle a first aid kit. It is therefore 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 released from the anchor point 2.

[0044] Following the injury, the user will attempt to reach the unlocked position, possibly using their only functional hand. The user will therefore operate one or the other of the two parts. It is therefore important that each of the two parts be securely attached to the support so that, upon release, the user holding one of the two parts of the lock 5 is connected to the fastening device.

[0045] If the user has only one functional hand, it is advantageous for the release mechanism of the fastening device 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 when unlocking the lock 5 and opening the blocker 4.

[0046] In a particularly advantageous embodiment illustrated in figures 1 to 8, in order to 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.

[0047] In an alternative embodiment illustrated in [Fig.9], the first part 9 is connected directly to the rigid tab 8.

[0048] 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 to the rigid tab 8 and preferably which extends the flexible element beyond the connection or even the fixing between the flexible element 11 and the rigid tab 8.

[0049] 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 provided 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 opening cover is attached to the plate 6' by fastening means that are actuated independently of the locking mechanism 4 in order to reduce the risk of loss of the opening cover when the locking mechanism 4 is in the open position. Figure 8 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 locking mechanism 6 is in the open position, and more preferably by using other fastening elements.

[0050] 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'.

[0051] 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, thereby ensuring the connection between the first part 9 and the support 6.

[0052] In a particularly advantageous embodiment, the flexible element 11 terminates at a first 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 will be for the rigid tab 8 to move, which complicates or makes it impossible to open 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, thus allowing it to adapt to different opening envelopes or envelopes that are more or less full.This embodiment is particularly advantageous when the hinged envelope can be separated from the 6' plate and / or when the hinged envelope has one or more flexible walls allowing deformation.

[0053] 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 intended to be located between a retaining wall of the support 6 and the rigid tab 8. The anchoring wall 2 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.

[0054] 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.

[0055] Figure 10 illustrates an 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 1 has one or more wire elements that define one or more anchor points 2.

[0056] As illustrated in Figures 1 to 9, the support 6 is preferably in the form of an openable envelope, for example in the form of a pouch and more preferably in the form of a first aid kit. For example, the support 6 contains first aid supplies, advantageously at least one bandage, an antiseptic, and possibly adhesive tape. The support 6 then forms a first aid kit.

[0057] It is conceivable that the openable envelope may contain equipment to be installed by the user other than equipment from a first aid kit. The openable envelope is openable, for example, by means of a zipper or any other means allowing the openable envelope to be opened to access its contents. The openable envelope may have any shape, preferably a parallelepiped, more preferably a rectangular parallelepiped.

[0058] 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 envelope 6 is between 1 and 1.5, preferably between 1 and 1.25, and more preferably between 1 and 1.1. The flexible element 11 can be provided 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 on 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.

[0059] As illustrated in Figures 1 to 4, it is advantageous to use a latch 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, which allows the user to differentiate, by touch, between the first part 9 and the second part 10. Another latch 5 is possible, for example, with a loop and a hook or a hooking material.

[0060] To form the hole 7, it is advantageous for the support 6 to have a wire element 13 that is projecting to form a hoop receiving the rigid tab 8 in the closed position. The wire element 13 can be a flexible element, for example, a rope, a strap, a braid, or a fabric. The use of a wire element 13 makes it easier to deform the hoop when the rigid tab 8 is in the open position, which makes it easier to detach the fastening device 1 from the anchor point 2.

[0061] 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 that 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.

[0062] Preferably, and as illustrated in Figures 1, 2 and 5 to 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.

[0063] The rigid tongue 8 will have more difficulty twisting than the flexible element 11 to follow the change in orientation of the walls materialized 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. By way of example, the rigid tongue 8 can be formed by a layer of wood, metal, composite material, or polymer material.

[0064] Preferably, the rigid tab 8 is arranged between the flexible loop and the support 3, so as to limit the possibilities of movement of the rigid tab 8 and introduce friction.

[0065] In a particular embodiment, the movable tab 8 is arranged to move only in translation within the slide defined by the hole 7 or holes between the closed and open positions. Movement that is only possible in translation makes accidental actuation of the movable tab 8 more difficult.

[0066] 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 slide 8 may be fixed to a portion of the wire element 9, or one end of the slide 8 may be able to slide relative to a portion of the wire element 9 only under certain conditions, in particular 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 causes the rigid tab 8 to move, thus opening 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.

[0067] Since the rigid tab 8 is integral with the flexible element 11 and the flexible element 11 is integral with the support 6, the action performed by the user to open the lock 4 ensures that at the moment of disengagement between the fastening device 1 and anchor point 2, the user will hold an element attached to the fastening device 1. The risk of loss of the fastening device 1 is very low or even zero.

[0068] In order to act on the latch 5 and the blocker 4 by actuation of the first part 9, various configurations are possible. Figures 1 to 5 illustrate one 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 makes moving the rigid tab 8 more complicated. 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 orifice through which the flexible element 11 passes.

[0069] Figure 6 illustrates another embodiment in which 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 the support 6 and the flexible element 11 from separating.

[0070] Figure 7 illustrates another embodiment corresponding to an alternative embodiment of Figure 6, where 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 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 hindered 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 can be a one-time connection, indicating that the support 6 has been used.

[0071] Figure 8 illustrates another alternative embodiment in which 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 termination 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 termination of the flexible element 11. The locking mechanism can be achieved by a wire element, for example, a rope or a strap.

[0072] Figure 9 illustrates yet another alternative where the rigid tongue 8 extends continuously from the 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 the use of a rigid tongue 8 extending 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, and with an injury. The use of 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 is longer than the second part. The first part is designed to fit into the hole 7.
