Definitions

  • the invention relates to a crampon intended to be secured to a footwear element such as a shoe.
  • This crampon can be used in areas such as mountaineering, walking on snow or ice, climbing cascading ice, or other.
  • the invention also relates to an assembly comprising a crampon and a footwear element such as a shoe.
  • a crampon comprises a body which extends in length from a first end to a second end, in width between a first edge and a second edge, and in height between a bearing face and a receiving face.
  • the body is sized so that the reception face receives the sole of the shoe.
  • the crampon comprises protruding points at the support face, to anchor the ground and thus oppose slips.
  • the body comprises a first portion extending in length from the first end to a first limit, and a second portion extending in length from the second end to a second limit.
  • the first part and the second part are connected to each other by a bridge, which serves in particular to adjust the length of the body.
  • Each part has tips, so allow forward anchors and anchors to the rear of the crampon.
  • the latter also includes a binding, that is to say a fastening system to the shoe within the meaning of NF EN 893: 2011-01.
  • the binding comprises one or more retaining members of the boot at the level of the receiving face.
  • the rigidity of a shoe used with the crampon is also an obstacle to the unwinding of the foot and walking.
  • the shoe is quite rigid, even very rigid, for several reasons. Firstly it must allow the fastening to the crampon by the standardized means, including a fastener that includes stirrups, or a stirrup and a lever mechanism. Then the shoe must offer good thermal resistance, which usually results in a large stem thickness and, consequently, increased rigidity. In the end it is the set comprising a crampon and the associated shoe which has a high rigidity, annoying for walking.
  • the general object of the invention is the improvement of a crampon intended to be secured to a footwear element such as a shoe.
  • the invention also seeks to improve an assembly which comprises a crampon and a shoe or, more generally, an assembly which comprises a crampon and a footwear element. More specifically, the invention seeks to facilitate walking with a crampon, or even to make walking as natural as that performed with a pair of soft shoes. In other words it is to allow a smooth running of the foot.
  • Another object of the invention is to reduce the fatigue of the user. This is to reduce the inertia of the crampon, and therefore its mass.
  • the invention proposes a crampon comprising a body which extends in length from a first end to a second end, in width between a first edge and a second edge, and in height between a bearing face. and a receiving face, the spike including projecting tips at the bearing face, the body including a first portion extending in length from the first end to a first limit, and a second portion extending in length from the second end to a second limit.
  • the crampon is characterized in that the first portion is longitudinally flexible, along a transverse axis, and in that the first portion is transversely rigid along a longitudinal axis.
  • the first part By its longitudinal flexibility the first part is able to adapt to curvatures and to follow the deformations in longitudinal flexion of a sole of a shoe, especially in the case where the latter is flexible. This allows the tips to contact the ground progressively during walking, in the sense that tips spaced longitudinally at the first part, contact the ground successively, one after the other. This makes walking easier and reduces user fatigue.
  • the first part allows the user to take more stable supports, or to better perceive the sensory information, even if a contact on the ground is done only at an edge. It also makes walking easier and reduces user fatigue.
  • a crampon that includes the first part according to the invention facilitates walking and reduces fatigue in all phases of use. It can be said that this crampon is more efficient than a crampon according to the prior art.
  • the invention improves a crampon intended to be secured to a footwear element such as a shoe, and an assembly comprising the crampon and the footwear element.
  • the first embodiment that will be described after concerns crampons for mountaineering, walking and running on snow or ice, as well as ice climbing.
  • the invention applies to other fields in which the use of such crampons is required.
  • An assembly 1 comprising a crampon 2 and a footwear element 3 is visible for example on the figure 1 .
  • the crampon 2 provided as will be seen later to be secured to the footwear element 3, comprises in known manner a body 4 which extends in length from a first end 5 to a second end 6, in width between a first edge 7 and a second edge 8, and in height between a bearing face 9 and a receiving face 10.
  • the bearing face 9 is provided to come facing the ground, while the receiving face 10 is intended to receive the footwear element 3.
  • the crampon 2 comprises points 15 protruding at the bearing face 9, as can also be seen on the figure 2 .
  • the crampon comprises eight tips 15, namely two at the first edge 7 and towards the first end 5, two at the second edge 8 and towards the first end 5, two at the second edge. 8 and towards the second end 6, and two at the first edge 7 and towards the second end 6. It is observed that at one edge the tips follow one another longitudinally. This amount of spikes 15 and their distribution are not limiting, and any other arrangement can be provided.
  • the body 4 comprises a first portion 16 which extends in length from the first end 5 to a first limit 17, and a second portion 18 which extends in length from the second end 6 to a second limit 19.
  • the first limit 17 and the second limit 19 are each located between the first end 5 and the second end 6 of the body 4.
  • the first part 16 and the second part 18 extend one another to form a single piece. It follows in this case that the first limit 17 and the second limit 19 merge with each other.
  • Each limit 17, 19 is a cross section of the body 4. We will see later the interest of such a configuration.
  • the first part 16 is longitudinally flexible, along a transverse axis W, and the first part 16 is transversely rigid, along a longitudinal axis L.
  • the body 4 is longitudinally flexible and rigid transversely. This allows the crampon 2 to adapt to the curvature of the sole of a footwear element such as a shoe, as well as to follow the longitudinal deformations in bending, during walking or running, while guaranteeing stable and reliable transversal supports, that is to say without unwanted skidding.
  • the first part 16 is a front part.
  • the body 4 of the crampon 2 is longitudinally flexible at the height of the toes and the metatarsus of the user, which is particularly useful for a freer running of the foot. Walking is therefore easier with the crampon of the invention rather than with a crampon according to the prior art.
  • the second portion 18 is longitudinally flexible, along a transverse axis W, and the second portion 18 is transversely rigid along a longitudinal axis L.
  • the body 4 is longitudinally flexible and rigid transversely.
  • the crampon 2 can adapt to the curvature of the sole of the footwear element 3, or follow the longitudinal flexural deformations, during walking or running, while ensuring stable and reliable transverse supports, without inadvertent skidding .
  • the second part 18 is a rear part.
  • the body 4 of the crampon 2 is longitudinally flexible at the height of the heel of the user, which is useful during a rear support.
  • a longitudinal deformation of the crampon increases the contact area between the rear portion 18 and the ground.
  • the sinking of the rear spikes 15 is more pronounced, which increases the adhesion or the grip on ice.
  • the security level is better.
  • the body 4 in its entirety that is longitudinally flexible, along a transverse axis W, and rigid transversely, along a longitudinal axis L.
  • This configuration optimizes the ability to walk or run with the crampon 2. It is observed in passing that the body 4 can deform in longitudinal twist along a longitudinal axis L, which results in a rotation of the front portion 16 relative to the rear portion 18 along said axis L. This further adds to the freedom of foot movement, for increased ease of walking.
  • the footwear element can either directly receive the foot of the user, or accommodate a walking shoe or race, not shown, itself intended to accommodate the foot of the user.
  • the footwear element 3 here comprises an outer sole 23 and a flexible upper 24.
  • the footwear 3 extends lengthwise from a front end or points 25 to a rear end or heel 26, and in width between a portion 27 and a medial portion 28.
  • the rod 24 comprises a first portion or lower portion 29, provided to surround the foot directly or via a shoe, and a second portion or upper portion 30 which extends the lower portion in a direction away from the outer sole 23, the upper portion 30 being provided to cover at least the user's ankle, or ankle and part of the lower leg.
  • the footwear element 3 has a continuous structure which gives it a good seal.
  • the footwear element 3 is also elastically deformable, to facilitate a boot or a heaving.
  • the footwear element 3 comprises clamping means, represented in the form of straps 31, 32 adjustable in length, to optimize the maintenance of the foot or the shoe received.
  • the assembly 1 has for example the general appearance shown on the figure 3 .
  • the external sole 23 which is flexible for a good unwinding of the foot, rests directly on the body 4 of the crampon 2.
  • the outer soleing 23 is secured to both the first part 16 and the second part. 18.
  • the outer soleing 23 is strictly opposite the body 4, the perimeter of the first 23 being between 90 and 110% of the perimeter of the second 4. This allows a direct transmission of the supports and sensory information between the foot and the ground. This also allows the body 4 to fully cooperate with the soleing 23 in all situations, as can be seen in the Figures 4 and 5 .
  • the first situation is where the assembly 1 is plated on a flat floor, which is not shown.
  • the sole 23 is supported on the body 4.
  • the tips 15 are in the position they occupy when the crampon 2 is not constrained.
  • two longitudinally successive front ends 15 located at the first edge 7 are parallel to one another. These points, whose respective directions are visualized by axes d1, d2, are for example parallel to each other.
  • the second situation corresponds to a phase of walking for which the front of the assembly 1 flexes.
  • the outer sole 23 and the body 4 flex. More precisely the first part 16, here part before, flexes.
  • the ends of the aforementioned points 15 move away from each other, their respective axes d1, d2 forming an angle ⁇ whose value may be a few degrees, or a few tens of degrees.
  • the crampon 1 comprises connecting means 35 provided to ensure a permanent connection of the crampon 2 to a footwear 3.
  • These means are represented in the form of rivets. They are a permanent link in the sense that they can not be disassembled with a tool.
  • Other means of permanent connection may be provided, such as glue, or any equivalent. These means are easy to use.
  • At least one part 16, 18 comprises a plate 16, 18, the plate having transverse slots 36, 37. These slots reduce the longitudinal flexural strength of the plate and, as a result, the parts 16, 18 bend more easily.
  • At least one transverse slot 36 has an open end 38. This facilitates the longitudinal bending of the body 4 along a transverse axis W and also facilitates the torsion of the body along a longitudinal axis L, while preserving the transverse rigidity in flexion along a longitudinal axis.
  • At least one transverse slot 37 has two closed ends 39, 40. This facilitates the longitudinal bending of the body 4 along a transverse axis W, while preserving the torsional rigidity and the transverse stiffness in flexion along a longitudinal axis .
  • the first embodiment of the invention combines the slots with an open end and the slots at both ends closed.
  • spikes 15 project at the bearing face 9 for the first part 16, and spikes 15 project at the bearing face 9 for the second part 18.
  • the tips are thus distributed towards the front and rear of the crampon 2. This provides ground anchoring capability both in the front and at the back, and promotes a smooth running of the foot.
  • At least one portion 16, 18 of the crampon 2 forms with one or more points 15 a single piece.
  • the two parts 16, 18 and all the points 15 form a single piece.
  • Simplification is maximum.
  • This part comprises for example synthetic or natural fibers embedded in a matrix made of resin or any equivalent material.
  • the piece can also be made with a metal, a metal alloy, or other.
  • the crampon 2 comprises connecting means 45 provided to ensure a non-permanent connection of the crampon to an element 3.
  • These means are represented in the form of screws. They constitute a non-permanent connection in the sense that they can be disassembled with a tool.
  • Other non-permanent connection means may be provided, such as spring locking mechanisms, or any equivalent. These means facilitate maintenance, worn or damaged elements can be changed.
  • the second embodiment has spikes 46 reported.
  • Each tip 46 may be reported by a permanent connection means or, alternatively, by a non-permanent connection means.
  • a non-permanent connection means there is provided a non-permanent connection means.
  • the connecting means 45 used for securing the crampon to the footwear element are the same as those used to secure the spikes 46 to the parts 16, 18 of the body 4. Again this facilitates maintenance.
  • the invention proposes a set 1 which comprises a crampon 2 and a shoe 3.
  • the footwear element is a shoe, flexible and suitable for walking and running.
  • the assembly according to the third embodiment is suitable for fast running on snow or ice.
  • the body 4 of the crampon 2 has only transverse slots 37 at the ends 39, 40 closed. This gives the body 4 good torsional stiffness along a longitudinal axis L.
  • the body 4 of the crampon 2 has both transverse slots 36 with an open end 38 and transverse slots 37 at the ends 39, 40 closed. This gives the body 4 a certain flexibility in torsion along a longitudinal axis L.
  • one or more longitudinal points 47 are secured to at least one of the first 16 and second 18 parts.
  • the front portion 16 carries two points 47 facing forward, to facilitate evolutions in the walls of snow or ice.
  • the first portion 16 and the second portion 18 are connected to each other by a bridge 48.
  • This allows for example an adjustment of the length of the body 4, and thus an adjustment of the length of the crampon.
  • An advantage that arises is to be able to adapt the crampon 2 to several sizes of shoes.
  • the crampon 2 comprises means for adjusting its length, means which comprise for example a screw-nut connection 49.
  • At least one portion 16, 18 of the crampon 2 comprises a corrugated sheet 50, the corrugated sheet having transverse ridges 51. More specifically, without limitation, the two parts 16, 18 comprise corrugated sheet, and form a part piece. It is simply a construction alternative, which can also include ways to adjust the length of the body.
  • At least one portion 16, 18 of the crampon comprises a longitudinal beam 52 and transverse arms 53. This is still a construction alternative.
