Description

Title of the invention: RIDING HARNESS PROVIDED WITH AN ADJUSTMENT DEVICE Technical field

[0001] The invention relates to a roping harness. Prior art

[0002] In acrobatic activities, the user moves vertically along a rope. The downward movement is easily achieved by allowing gravity to act and adjusting the sliding speed. On the other hand, ascending the rope is a more energy-intensive operation. To prevent the user from tiring prematurely while ascending the rope, we seek to improve the efficiency of the operation of sliding upwards along the rope and then locking on the rope.

[0003] In order to increase the efficiency of the rope ascent operation on a single rope, it is particularly advantageous to use a rope ascender for each of the user's two feet. One of the rope ascenders, for example the right ascender, is attached directly to one foot of the user while the other rope ascender (the left ascender) is connected to the other foot by a strap so that the rope ascenders do not interfere with each other. In order to move the left ascender upwards, it is known to connect this ascender to an upper part of the body by means of an elastic band so as to mechanically stress the left ascender upwards when the left foot is not stressing the left ascender. This solution gives good results but it results in the management of a cumbersome rope ascender system when the user arrives at his working position and must move to carry out his work.

[0004] In an alternative, the rigid mechanical connection that exists between the two foot blockers which are connected to the right and left feet in the same way as before. The assembly formed by the right foot and the left foot is connected to the upper part of the body by means of an elastic element. For example, the elastic is fixed to the shoulders or to the body blocker. Here again, it is possible to note that the size of the rope ascent system is significant when the latter is no longer used and must be stored on the roping harness.

[0005] It is also known to replace a foot blocker with a knee blocker whose operation is identical, that is to say a blocker which is arranged at knee height and which is connected to the foot.

[0006] In order to facilitate the management of the elastic wire element which is connected to the rope blocker, it is known to modify a harness belt to attach a sheath to the top of the belt and to install the elastic wire element in the sheath. However, this construction generates other problems in use with accelerated wear of the belt. Subject of the invention

[0007] An object of the invention is to provide a roping harness which is easier and more pleasant to use during rope ascent operations and during rope descent operations and whose management of the rope ascent system is better integrated.

[0008] This result is achieved by means of a rope harness comprising: - a belt with a pad arranged between an external wall and an internal wall, - a pair of leg loops; - at least one elastic wire element mounted integral with the belt, the at least one elastic wire element having one end mounted movable relative to the belt by elastic deformation of the elastic wire element, the end having a connector.

[0009] The roping harness is remarkable in that: - the lining defines at least one channel receiving a portion of the at least one elastic wire element; - the external wall defines at least one right through hole or one left through hole opening into the lining, the elastic wire element passing through the at least one right through hole or left through hole so that the end of the at least one elastic wire element is arranged outside the at least one channel; - the at least one channel has a first thickness; - the at least one elastic wire element has a second thickness less than or equal to the first thickness.

[0010] According to a preferred aspect of the invention, the outer wall defines a right through hole and a left through hole. The at least one channel is a channel extending continuously from the right through hole to the left through hole.

[0011] Advantageously, the at least one elastic wire element is an elastic wire element extending continuously to pass through the right through hole and the left through hole, each end of the elastic wire element being terminated by a connector.

[0012] Preferably, the elastic wire element is continuously sliding and stretchable between the right through hole and the left through hole.

[0013] In a particular configuration, at least one sheath is disposed in the at least one channel, the at least one channel receiving the at least one elastic wire element. The at least one sheath has a third thickness less than the second thickness.

[0014] In an advantageous development, the external wall has a rigidity greater than a rigidity of the lining in a longitudinal direction and / or a transverse direction which are perpendicular to a thickness direction.

[0015] Preferably, the at least one sheath is fixed to the external wall.

[0016] According to one embodiment, the sheath is separated from the internal wall by a portion of garnish.

[0017] In an advantageous development, in a rest position, each end of the at least one elastic wire element bears against an openwork plate attached to the external wall.

[0018] In another advantageous development, the at least one end is attached to a rope blocker intended to form a right foot blocker or a left foot blocker. Summary description of the drawings

[0024] [Fig.l] illustrates an embodiment of a roping harness 1 which is provided with a belt 2, a pair of leg loops 3 and a wire element 4 one end of which is mounted to move relative to the belt 2 to move towards or away from a foot of a user wearing the roping harness 1.

[0025] The belt 2 has an inner wall 2a, a lining 2b and an outer wall 2c. The inner wall 2a, the lining 2b and the outer wall 2c are arranged successively in a thickness direction. The inner wall 2a is intended to come into contact with the user, the lining 2b is separated from the user by the inner wall 2a. In a particular embodiment, the inner wall 2a and the outer wall 2c join on their peripheral parts to form an envelope receiving the lining 2b.

[0026] The outer wall 2c defines at least one through hole which is a right through hole 5a or a left through hole 5b. Preferably, the outer wall 2c defines a right through hole 5a as well as a left through hole 5b. The right through hole 5a and the left through hole 5b are separated by the median sagittal plane of the user wearing the roping harness 1. Preferably, the right through hole 5a is arranged facing the right iliac fossa while the left through hole 5b is arranged facing the left iliac fossa when the roping harness 1 is worn by a user who is standing. The opposite is observed in a direction normal to the median sagittal plane.

[0027] The lining 2b defines at least one channel 6 intended to receive a portion of the elastic wire element 4. A portion of the elastic wire element 4 is arranged in the channel 6. The through hole 5 is arranged facing the channel 6 to allow the elastic wire element 4 to pass through the through hole 5 and to allow one end of the elastic wire element 4 to move relative to the belt 2 by elastic deformation of the elastic wire element 4.

[0028] In one embodiment, the outer wall 2c defines a right through hole and a left through hole. This configuration makes it possible to have a rope harness 1 adapted to a user whose rope stopper 7 connected to a foot or knee by a strap or rope is the right or left foot / knee.

[0029] The roping harness 1 may have a single elastic wire element 4 which emerges from the external wall 2c through each of the two through holes 5. Alternatively, the roping harness 1 has a right elastic wire element and a left elastic wire element. Preferably, the fitting 2b defines a single channel 6 which extends from the right through hole to the left through hole. A fitting 2b which defines a right channel and a left channel is also possible.

[0030] The roping harness 1 has at least one elastic wire element 4 which is arranged in the at least one channel 6 between the inner wall 2a and the outer wall 2c. The at least one elastic wire element 4 passes through the outer wall 2c by passing through the through hole 5 so as to be able to extend up to a knee or a foot. Furthermore, it is particularly advantageous that in its rest position, that is to say without external stress, the end of the elastic wire element 4 is in abutment against the belt part 2 defining the through hole 5, that is to say that the vast majority of the elastic wire element 4 is stored in the belt 2.

[0031] The distance between the iliac fossa and the knee or between the iliac fossa and the foot is relatively large compared to the length of the dorsal part of the belt 2 capable of storing the elastic wire element 4. It is therefore advantageous to have an element elastic wire as long as possible to limit the elongation of the elastic wire element 4 and thus have an elastic force better adapted to raise the rope blocker 7 in the absence of stress.

[0032] It is particularly advantageous to have an elastic wire element 4 which extends continuously from the right through hole to the left through hole and which is continuously slidable between the right through hole and the left through hole. In addition to being suitable for a user whose supporting foot is a right foot or a left foot, the elastic wire element 4 has a length which is substantially equal to the distance which separates the right through hole and the left through hole and all of this length of the elastic wire element 4 is used. The elastic wire element 4 is mounted continuously slidable relative to the lining 2b between the right through hole and the left through hole.

[0033] The installation of the elastic wire element 4 inside the belt 2 between the internal wall 2a and the external wall 2c makes it possible to functionalize the interior of the belt 2. The elastic wire element 4 no longer needs to be demonstrated and then hung after use, it is automatically stored in the belt 2.

[0034] The installation of the channel 6 inside the belt 2 instead of the top of the belt 2 makes it possible to improve the mechanical connection between the belt 2 and the elastic wire element 4. The forces applied downwards when stressing the end of the elastic wire element 4 are better absorbed by the external wall 2c.

[0035] It is particularly advantageous to attach the elastic wire element 4 to a resistance element 8 which ensures the mechanical resistance of the rope harness 1 in the event of a fall.

[0036] Preferably, the belt 2 defines a sheath 9 and the elastic wire element 4 is arranged inside the sheath. It is particularly advantageous for the belt 2 to be provided with a right through hole 5a and a left through hole 5b and for the sheath 9 to define a path for the elastic wire element 4 to pass between the right through hole 5a and the left through hole 5b. For example, the sheath 9 extends continuously from the right through hole 5a to the left through hole 5b. The elastic wire element 4 can slide freely along the sheath 9. It is also possible for the sheath 9 to be formed by elementary sheaths arranged at a distance from each other to define the path.

[0037] When the path is a straight line between the right through hole 5a and the left through hole 5b, it is advantageous to fix the elementary sheaths to the internal wall 2a. The forces in the longitudinal direction are absorbed by the external wall 2c and / or the resistance element 8.

[0038] It is also possible for the sheath 9 to be attached to the external wall 2c which is chosen to have increased rigidity compared to the lining 2b so as to to withstand the stresses on the elastic wire element 4. The stress of the rope blocker 7 attached to the end of the elastic wire element 4 causes a stress on the external wall 2c or the resistance element 8. It is advantageous to mechanically separate the lining 2b and the sheath 9 to avoid deforming the lining 2b and creating an area of ​​discomfort in the examiner's back.

[0039] The lining 2b defines at least one channel 6 which has a first thickness. The first thickness is greater than the second thickness which is the thickness of the elastic wire element 4 which makes it possible to avoid having an excess thickness linked to the elastic wire element 4 relative to the external face of the external wall 2c and relative to the internal face of the internal wall 2a. The presence of a bead on the internal face 2a introduces an area of ​​discomfort. The presence of a bead on the external face 2c introduces an area of ​​accelerated wear.

[0040] When the belt 2 is provided with a sheath 9 which receives the elastic wire element 4, the sheath 9 has a third thickness. The third thickness is greater than the first thickness and less than the second thickness so as not to have any excess thickness linked to the assembly formed by the sheath 9 and the elastic wire element 4 relative to the external face of the external wall 2c and relative to the internal face of the internal wall 2a.

[0041] The at least one elastic wire element 4 extends beyond the outer wall 2c to move towards a thigh circumference 3 and towards a foot or a knee. The right part of the at least one elastic wire element 4 passes through the right through hole 5a and can support the right connector 10. The left part of the at least one elastic wire element 4 passes through the left through hole 5b and can support the left connector 10. The elastic wire element 4 has an inflection when leaving the channel 6 to move towards a knee or foot. Preferably, the belt 2 comprises a right plate 11 and / or a left plate 11 which define a through orifice which opens opposite the right through hole 5a and the left through hole 5b. The plate 11 projects from the outer wall 2c. The plate 11 defines an outlet whose outlet direction is directed downwards.The output direction is arranged in the angular range between the average longitudinal direction of the elastic wire element between the right through hole and the left through hole as well as the longitudinal direction of a leg of a user who wears the rope harness 1 in a standing position, with both feet on the ground.

[0042] The plate 11 makes it possible to introduce an inflection of the elastic wire element 4 in order to reduce friction to facilitate the transmission of forces and limit the wear of the elastic wire element 4. The plate 11 defines a sliding zone for the elastic wire element 4.

[0043] The plate 11 makes it possible to protect the elastic wire element immediately upon exiting the external wall 2c.

[0044] Preferably, the end of the elastic wire element 4 has a connector 10 which is for example a knot or any other fixing means. The connector 10 prevents the end of the elastic wire element 4 from passing through the through hole 5 and through the plate 11 if necessary. The end connector 10 of the elastic wire element 4 can also be a carabiner, a shackle, a quick link or any other device capable of receiving a rope blocker. An additional connector 12 can be used to connect the connector 10 and the rope blocker 7.

[0045] During its use, the connector 10 can directly or indirectly hook a rope connector 7 which is hooked to a foot or a knee. During the rope ascent phases, the foot or the knee moves towards and then away from the belt 2. The rope blocker 7 makes a back and forth movement relative to the belt 2. The elastic wire element 4 relaxes and contracts alternately to follow the extensions of its attachment leg. The elastic wire element 4 enters and then leaves the channel 6. When the user's leg forces the rope blocker 7 downwards, the leg applies a force to the elastic wire element 4 which elastically deforms it in extension. A portion of the elastic wire element 4 leaves the channel 6. When the leg reduces the stress on the elastic wire element 4, the elastic wire element 4 contracts and at least partially returns to the channel 6.

[0046] In a preferred embodiment illustrated in [Fig.2], the lining 2b and the inner wall 2a are formed by the same part. The lining 2b defines a groove which forms a channel 6. The groove does not pass through the element forming the inner wall and the lining 2b in the thickness direction in order to define an inner wall 2a locking the elastic wire element 4 in the belt 2. The outer face 2a' by the upper image while the inner face 2a” is illustrated by the lower image.

[0047] [Fig. 3] illustrates the steps of manufacturing a belt 2 of a rope harness 1. Figure 3a illustrates a reinforcing element 2c' which supports elementary sheaths 9 and an elastic wire element 4. Figure 3b the assembly of the reinforcing element 2c' and the elastic wire element 4 with the lining 2b. Figure 3c illustrates the assembly of the external wall 2c on the lining 2b associated with the reinforcing element 2c'.

[0048] In the illustrated embodiment, the reinforcing element 2c' defines the position of the multiple elementary sheaths 9 receiving the elastic wire element 4. The lining 2b defines a channel 6 and the elastic wire element 4 already shaped by means of the elementary sheaths 9 fixed to the reinforcing element is installed in the channel by installing the reinforcing element 2c'. The external wall 2c is installed on the element of reinforcement 2c' and on the lining 2b to block the reinforcement element 2c' between the internal wall 2a and the external wall 2c.

[0049] Preferably, the external wall 2c defines slots 13 for the passage of the resistance element 8. The external wall 2c defines a right through hole 2a and a left through hole 5b whose shapes are arranged to receive plates 11.

[0050] The elastic wire element 4 may be formed by an element which is homogeneous from one end to the other, advantageously with an elongation rate greater than 50%, by a cord or a strap which is elastically deformable. Alternatively, the elastic wire element is made in several parts which have different elongation values ​​at break. The end may be formed by an element having a lower elongation at break than the part intended to be in the channel 6.

[0051] As illustrated in [Fig.l], it is advantageous for the resistance element 8 to be in the form of a strap terminated by an opening-closing device 13 configured to define an open position and a closed position. In the open position, the user can put on or take off the roping harness 1. In the closed position, the user and the roping harness 1 are inseparable.

[0052] The belt 2 may have one or more anchor points 2d which are fixed to the resistance element 8 so as to ensure the suspension of the user installed in the rope harness 1.

[0053] In the embodiment illustrated in [Fig. 3], the reinforcing element 3c' is provided with spacers 14 which make it possible to space the lining 2b and the external wall 2c.
