Abstract
Description
Technical Field
[0001] This invention relates to a claw spike designed to prevent the user from slipping when using it for snow mountaineering or mixed terrain climbing. Background Technology
[0002] When engaging in mountain sports (such as mountaineering), especially when hiking on ice or climbing icefalls, it is necessary to secure the cleats to the boots to prevent the user from slipping.
[0003] The use of crampon spikes of the above type is known in the prior art, wherein the spikes are provided with spikes to prevent slipping. Generally, the spikes are distributed across the entire underside of the foot, from the front to the rear of the spike. Generally, the spike consists of a front part and a rear part.
[0004] Some current technological solutions propose a crampon spike with a longer front component to allow for more spikes to be placed under the boot. Another approach, described in document DE7529410U, involves proposing a crampon spike with more than two structural components (particularly a middle component with spikes). These solutions are satisfactory because they enable crampon-equipped boots to have better grip on ice.
[0005] However, increasing the size of the front component or adding the middle component increases the weight of the crampon spikes and reduces the overall ergonomics and compactness of the spikes when they are not mounted on the boot, such as when they are stored or transported. Summary of the Invention
[0006] The purpose of this invention is to provide a solution that solves all or some of the problems described above.
[0007] Specifically, the present invention aims to satisfy at least one of the following objectives:
[0008] - It is recommended to have good grip on icy surfaces;
[0009] - Lightweight;
[0010] -Small size and highly compact;
[0011] - Easy to store.
[0012] This objective can be achieved by implementing a crampon stud for fastening to a boot, the crampon stud comprising:
[0013] - Front component, which includes at least one pair of front spikes offset from each other in the lateral direction of the front component;
[0014] - Rear component, which includes at least one pair of rear spikes offset from each other in the lateral direction of the rear component;
[0015] - At least one flexible connector that connects the front and rear components to each other along the longitudinal direction of the crampon spike;
[0016] - At least one middle component, which is mounted on the flexible connector by being positioned between the front component and the rear component, said at least one middle component includes at least one pair of middle spikes offset from each other in the lateral direction of the middle component;
[0017] The at least one pair of front spikes, the pair of rear spikes, and the at least one pair of middle spikes are configured to prevent the crampon spikes from sliding on the ground (especially icy ground);
[0018] The front component, the rear component, and the at least one middle component are hinged independently to each other at least along the longitudinal direction and along the lateral direction, and
[0019] The position of the middle component can be adjusted relative to the flexible connector along the longitudinal direction.
[0020] The previously described arrangement (especially the presence of the flexible connector) allows for the separate hinge of the front component, rear component, and at least one middle component. In this way, the crampon spikes can be adapted to different boot sizes. Furthermore, adjustment of the middle component by means of at least one flexible connector allows, for example, the middle component to be placed adjacent to the front or rear component and allows its position to be frozen once the crampon spikes are tensioned on the boot. In this way, the position of the middle component can be adjusted longitudinally on the flexible connector to adapt to the terrain or the user's practice.
[0021] Crampon spikes may further have one or more of the following features, which may be used individually or in combination.
[0022] According to one embodiment, at least one flexible connector is configured to allow the middle component to be positioned on the front or rear component in an inbutment manner. In this way, user comfort during climbing can be improved.
[0023] According to one embodiment, at least one flexible connector is configured to continuously adjust the position of the central component relative to the flexible connector along its entire length. Therefore, fine adjustment of the central component along the length of the flexible connector is possible.
[0024] According to one embodiment, adjustment of the central component on the flexible connector is achieved through friction. In this way, by sliding the central component along the length of the flexible connector, its position can be adjusted easily during use of the crampon spikes. Therefore, adjustment of the central component's position can be performed quickly without the need for special tools such as screwdrivers.
[0025] According to one embodiment, at least one flexible connector is configured to continuously adjust the position of the rear component relative to the flexible connector along its entire length. Therefore, fine adjustment of the rear component along the length of the flexible connector is possible.
[0026] According to one embodiment, adjustment of the rear component on the flexible connector is achieved through friction. In this way, by sliding the rear component along the length of the flexible connector, the position of the rear component can be adjusted easily during use of the crampon spikes. Therefore, adjustment of the rear component's position can be performed quickly without the need for special tools such as screwdrivers.
[0027] According to one embodiment, at least one flexible connector is made as a single piece that extends integrally between the front component and the rear component.
[0028] According to one embodiment, the front component includes a front connecting element configured to connect the front component to the at least one flexible connector, and wherein the rear component includes a rear connecting element configured to connect the rear component to the at least one flexible connector, and the middle component is configured to be detachable from the flexible connector at either the rear or front connecting element.
[0029] In this way, the middle part can be completely removed from the crampon spikes, for example, to increase the compactness and lightness of the crampon spikes to accommodate users practicing with them.
[0030] According to one embodiment, the at least one flexible connector is configured to be length-adjustable to adjust the distance between the rear and front components. Advantageously, the rear and front connecting elements enable length adjustment of the at least one flexible connector. The previously described arrangement allows for the development of a crampon spike in which a length adjustment system is incorporated. Furthermore, the length adjustment is continuous along the flexible connector for ultra-fine length adjustment.
[0031] According to one embodiment, the front connecting element includes a front recess, on which at least one flexible connector is inserted, the at least one flexible connector having a width smaller than the lateral dimension of the front recess along the lateral direction of the front component.
[0032] According to one embodiment, the rear connecting element includes a rear recess, on which at least one flexible connector is inserted, the at least one flexible connector having a width smaller than the lateral dimension of the rear recess along the lateral direction of the rear component.
[0033] According to one embodiment, the crampon spike includes a single flexible connector with a width sufficient to ensure the stability of the crampon spike, such that the front, middle, and rear components remain substantially parallel to each other. For example, the width of the flexible connector is greater than 3 cm when calculated perpendicular to the longitudinal direction of the crampon spike.
[0034] Advantageously, the use of a wider flexible connector can improve the lateral holding force of the crampon spikes. Furthermore, the combination of a wide flexible connector with smaller front, middle, and rear components allows for good stability of the boot on the ground and enables the provision of crampon spikes that are both compact and lightweight.
[0035] In addition, the wide flexible connectors can help adjust the position of the middle component along the flexible connectors, as well as adjust the size of the front and rear components.
[0036] "Wide" should be understood as the width of the flexible connector that is greater than one-third of the width of at least one central component (calculated in the lateral direction of at least one central component).
[0037] According to one embodiment, when crampon spikes are fastened to the boot, at least one flexible connector is subjected to longitudinal tension.
[0038] For example, the longitudinal tension is greater than 40N, more specifically greater than 50N, and especially approximately equal to 60N.
[0039] According to one embodiment, at least one flexible connector is made of a rigid material such that when the crampon spike is tensioned longitudinally, the elongation of the flexible connector is less than 15%.
[0040] For example, the material of at least one flexible connector may include ultra-high molar mass polyethylene and / or high-toughness polyester, thereby ensuring an elongation of less than 3%.
[0041] According to this embodiment, the longitudinal tension borne by the flexible connector between the front and rear components ensures frictional locking of the middle component along the longitudinal position of the flexible connector.
[0042] According to one embodiment, the crampon spikes include two lateral flexible connectors.
[0043] The previously described device allows for lateral stability of the boot on the crampon spikes, particularly by preventing relative rotation of the front, rear, and middle components, especially when the crampon spikes are longitudinally tensioned. In other words, the previously described arrangement allows for suppression of lateral pivoting of the crampon spikes.
[0044] According to one embodiment, each flexible connector may be selected from: a cable, a strap, or a rope.
[0045] According to one embodiment, the front component, the rear component, and at least one middle component are configured to nest with each other when they are stacked relative to each other in the lateral direction of the crampon spikes.
[0046] According to one embodiment, at least one flexible connector is configured to allow the crampon spike to change between an unfolded configuration and a nested configuration. In the unfolded configuration, the crampon spike can be fastened to the boot, and in the nested configuration, the front component, the rear component, and at least one middle component are nested within each other. Therefore, it is readily understood that the flexibility of the flexible connector allows the crampon spike to fold itself, particularly allowing it to be stored when in the nested configuration.
[0047] According to one embodiment, the crampon spike remains intact when it changes between an unfolded configuration and a nested configuration. Therefore, it is easy to understand that removing the crampon spike to create a nested configuration is unnecessary.
[0048] According to one embodiment, when the front component, the rear component, and at least one middle component are nested together, they are included within a 450mm radius. 3 In the volume.
[0049] According to one embodiment, when the front component, the rear component, and at least one middle component are nested together, they are included in a parallelepiped having a lateral dimension between 35 mm and 70 mm, a longitudinal dimension between 75 mm and 150 mm, and a transverse dimension between 75 mm and 150 mm.
[0050] The previously described arrangement allows the crampon spikes to be folded when not in use. This allows the crampon spikes to be very compact when folded during transport or storage. Furthermore, the overall weight of the crampon spikes can be very light.
[0051] According to one embodiment, the front component includes a front platform for receiving the front portion of the boot, and wherein the rear component includes a rear platform for receiving the rear portion of the boot, the front platform and the rear platform having a length in the longitudinal direction, the length being between 3 cm and 6 cm, particularly approximately equal to 4 cm.
[0052] According to one embodiment, the front component includes a front fastener, and the rear component includes a rear fastener, at least one of the front and rear fasteners including a lever configured to support a shoulder (which is included on a portion of the boot) and to longitudinally tension at least one flexible connector when the front and rear portions of the boot are respectively fastened to the crampons by means of the front and rear fasteners of the crampons.
[0053] Advantageously, the presence of the middle component allows for limiting the length of the front and rear platforms while maintaining the grip of the crampons on the ice.
[0054] According to one embodiment, the rear component includes a rear fastener configured to support a shoulder portion included on the rear portion of the boot.
[0055] According to one embodiment, the rear fastener is a wire that applies pressure to the boot to prevent a relative gap between the boot and the crampon spikes.
[0056] According to one embodiment, the rear fastener includes a lever configured to longitudinally tension at least one flexible connector when the front portion of the boot is secured to the crampon spikes by means of the front fastener.
[0057] According to one embodiment, the lever is configured to tension the rear fastener on the shoulder.
[0058] According to one embodiment, crampon spikes may include a stop band, which is provided, for example, at a lever and configured to attach around the boot.
[0059] According to one embodiment, the front component includes a front fastener for securing the front component to the front portion of the boot. For example, the front fastener may be configured to support the shoulder portion included in the front portion of the boot.
[0060] According to one embodiment, the front fastener is a wire that applies pressure to the boot to prevent a relative gap from forming between the boot and the crampon spikes.
[0061] According to one embodiment, the front fastener includes a lever configured to longitudinally tension at least one flexible connector when the rear portion of the boot is secured to the crampon spikes by means of the rear fastener.
[0062] According to one embodiment, the lever is configured to tension the front fastener on the front shoulder of the boot.
[0063] According to one embodiment, the front fastener is rigid and configured to automatically conform to the shape of the front portion of the boot.
[0064] According to another embodiment, the front fastener is semi-rigid; for example, the front fastener may include an adjustable band. Attached Figure Description

[0070] In the accompanying drawings and the following description, the same reference numerals denote the same or similar elements. Furthermore, for the sake of clarity, different elements are not shown to scale. Moreover, different embodiments and variations are not mutually exclusive and can be combined together.
[0071] like Figure 1 As shown, the present invention relates to a crampon stud 1 for fastening to a boot.
[0072] The crampon spike 1 includes a front component 200, a rear component 300, at least one middle component 400, and a flexible connector 500.
[0073] The front component 200 includes at least one pair of front spikes 202 that are offset from each other in the lateral direction of the front component 200.
[0074] According to one embodiment, the front component 200 includes a front fastener 210 for securing the front component 200 to the front portion of a boot.
[0075] For example, the front fastener 210 may be rigid and configured to automatically conform to the shape of the front portion of the boot.
[0076] Alternatively, the front fastener 210 may be semi-rigid, for example, the front fastener 210 may include a belt.
[0077] The rear component 300 includes at least a pair of rear spikes 302 that are offset from each other in the lateral direction of the rear component.
[0078] Figure 1 One embodiment is shown in which the rear component 300 includes a rear fastener 310 configured to support the shoulder of the rear portion of the boot. Figure 2 A configuration is shown in which crampon spikes 1 are fastened to the boot.
[0079] According to a non-limiting variant, the rear fastener 310 is a wire that applies pressure to the boot to prevent a relative gap between the boot and the crampon spike 1.
[0080] According to another non-limiting variation, the rear fastener 310 includes a lever 312 configured to longitudinally tension at least one flexible connection 500 when the front portion of the boot is secured to the crampon spikes 1 by means of the front fastener 210. For example, when the front fastener 210 includes a rigid or semi-rigid stop, at least one flexible connection 500 can be tensioned by the lever 310.
[0081] Advantageously, lever 312 may include a micro-adjustment system 316 (e.g., a threaded component) configured to adjust the height of lever 312 relative to the shoulder of the boot. In this way, when crampon spikes 1 are tensioned on the boot, crampon spikes 1 can be adapted to different boot types or to the possible elongation of the flexible connection 500.
[0082] Alternatively or commonly, the crampon spike 1 may include a stop band 314, which is provided, for example, at the lever 312 and configured to attach around the boot.
[0083] According to one embodiment, the front component 200 includes a front platform 208 for receiving the front portion of the boot, and the rear component 300 may include a rear platform 308 for receiving the rear portion of the boot.
[0084] According to this embodiment, the lengths of the front platform 208 and the rear platform 308 along the longitudinal direction can be included between 3 cm and 6 cm, especially approximately equal to 4 cm.
[0085] As described above, the crampon spike also includes at least one flexible connector 500 that connects the front component 200 and the rear component 300 to each other along the longitudinal direction of the crampon spike 1. For example, the at least one flexible connector 500 is made as a single piece that extends integrally between the front component 200 and the rear component 300.
[0086] according to Figure 1In the non-limiting variant shown, the front component 200 includes a front connecting element 204 configured to connect the front component 200 to the at least one flexible connector 500.
[0087] The front connecting element 204 may specifically include a front recess 206 into which at least one flexible connector 500 is inserted, the at least one flexible connector 500 having a width smaller than the lateral dimension of the front recess 206 along the lateral direction of the front component 200.
[0088] Alternatively or commonly, the rear component 300 may include a rear connecting element 304 configured to connect the rear component 300 to the flexible connector 500.
[0089] The rear connecting element 304 may include a rear recess 306 into which at least one flexible connector 500 is inserted, the at least one flexible connector 500 having a width smaller than the lateral dimension of the rear recess 306 along the lateral direction of the rear component 300.
[0090] According to one embodiment, the at least one flexible connector 500 is configured to have an adjustable length. Advantageously, the rear connecting element 304 and the front connecting element 204 enable length adjustment of the at least one flexible connector 500.
[0091] According to one embodiment, the crampon spike 1 includes a single flexible connector 500, the width of which is sufficient to ensure the stability of the crampon spike, such that the front, middle, and rear components remain parallel to each other, particularly when the crampon spike 1 is longitudinally tensioned after being fastened to the boot. For example, the width of the flexible connector can be greater than 3 cm when calculated perpendicular to the longitudinal direction of the crampon spike 1.
[0092] According to another embodiment not shown, the crampon spike 1 includes two flexible lateral connectors 500.
[0093] According to one embodiment, each flexible connector 500 may consist of a cable, a strap, or a rope.
[0094] The crampon spikes 1 also include at least one central component 400, which is mounted on the flexible connector 500 by being positioned between the front component 200 and the rear component 300. The at least one central component 400 includes at least a pair of central spikes 402 that are offset from each other in the lateral direction of the central component 400.
[0095] Advantageously, the middle component 400 can be configured to be detachable from the flexible connector 500 at the rear connecting element 304 or the front connecting element 204. In this way, the middle component 400 can be completely removed from the crampon spike 1, for example to promote the compactness and lightness of the crampon spike 1 to accommodate the user practicing with the crampon spike 1.
[0096] The at least one pair of front spikes 202, the at least one pair of rear spikes 302, and the at least one pair of middle spikes 402 are configured to prevent the crampon spikes 1 from sliding on the ground (especially on icy ground).
[0097] Furthermore, the front component 200, the rear component 300, and the at least one middle component 400 are hinged to each other independently at least along the longitudinal direction and along the lateral direction.
[0098] Finally, the position of the middle component 400 can be adjusted relative to the flexible connector 500 in the longitudinal direction. Advantageously, at least one flexible connector 500 can be configured to allow the middle component 400 to be positioned on the front component 200 or the rear component 300 in a pier-like manner.
[0099] As shown in the figure, at least one flexible connector 500 is configured to continuously adjust the position of the central component 400 relative to the flexible connector 500 along its entire length. Specifically, the adjustment of the central component 400 on the flexible connector 500 can be achieved through friction.
[0100] Furthermore, it can be specified that at least one flexible connector 500 is configured to continuously adjust the position of the rear member 300 relative to the flexible connector 500 along its entire length. Specifically, the adjustment of the rear member 300 on the flexible connector 500 can be achieved through friction.
[0101] The previously described arrangement allows the crampon spikes 1 to be fastened to the boot.
[0102] According to one embodiment, when the crampon spike 1 is fastened to the boot, at least one flexible connector 500 is subjected to longitudinal tension.
[0103] For example, the longitudinal tension is greater than 40N, more specifically greater than 50N, and especially approximately equal to 60N.
[0104] Advantageously, the longitudinal tension borne by the flexible connector 500 between the front member 200 and the rear member 300 provides positive locking of the middle member 400 along the longitudinal position of the flexible connector 500, for example by friction.
[0105] According to one embodiment, the material of at least one flexible connector 500 has a certain rigidity such that when the crampon spike 1 is longitudinally tensioned, the elongation of the flexible connector is less than 15%.
[0106] For example, the material of at least one flexible connector 500 may include ultra-high molar mass polyethylene and / or high toughness polyester, thereby ensuring an elongation of less than 3%.
[0107] The presence of the middle component 400 specifically allows for limiting the length of the front platform 208 and the rear platform 308 while maintaining the grip performance of the crampon spikes 1 on the ice.
[0108] When the crampon spikes 1 are not fastened to the boot, the previously described arrangement (in particular the presence of the flexible connector 500) allows for separate articulation of the front component 200, the rear component 300, and at least one middle component 400.
[0109] In this way, and as Figure 3 As shown, the front component 200, the rear component 300 and at least one middle component 400 are configured to nest with each other when they are stacked relative to each other in the lateral direction of the crampon spike 1.
[0110] For example, when the front component 200, the rear component 300, and at least one middle component 400 are nested together, they are contained within a 450mm radius. 3 In the volume.
[0111] Alternatively or collectively, the front component 200, the rear component 300, and at least one middle component 400 may be contained in a parallelepiped when nested together, the parallelepiped having a lateral dimension between 35 mm and 70 mm, a longitudinal dimension between 75 mm and 150 mm, and a transverse dimension between 75 mm and 150 mm.
[0112] Therefore, advantageously, at least one flexible connector 500 is configured to allow the crampon spike 1 to change between an unfolded configuration and a nested configuration, in which the crampon spike 1 can be fastened to the boot, and in the nested configuration, the front component 200, the rear component 300, and at least one middle component 400 nest together. Thus, it is readily understood that the flexibility of the flexible connector 500 allows the crampon spike 1 to fold itself, particularly allowing it to be stored when the flexible connector is in the nested configuration.
[0113] According to one embodiment, the crampon spike 1 remains intact when it changes between an unfolded configuration and a nested configuration. Therefore, it is easy to understand that it is unnecessary to remove the crampon spike 1 to allow it to occupy the nested configuration.
[0114] Therefore, the crampon spike 1 can fold itself when not in use. This allows for increased compactness of the crampon spike 1 in its folded position during transportation or storage. Furthermore, the overall weight of the crampon spike 1 can be very light.
[0115] Finally, advantageously, the use of a wide flexible connector 500 can improve the lateral holding force of the crampon spikes 1. Furthermore, the combination of the wide flexible connector 500 with the smaller front component 200, middle component 400, and rear component 300 allows for good stability of the boot on the ground and allows for the provision of crampon spikes 1 that are both compact and lightweight.
[0116] In addition, the wide flexible connector 500 can help adjust the position of the middle component 400 along the flexible connector 500 as well as adjust the dimensions between the front component 200 and the rear component 300.
[0117] "Wide" should be understood as the width of the flexible connector 500 being larger than one-third of the width of at least one central member 400 calculated in the lateral direction of at least one central member 400.
[0118] The previously described device allows for lateral stability of the boot on the crampon spike 1, particularly by preventing relative rotation of the front part 200, rear part 300, and middle part 400, especially when the crampon spike 1 is longitudinally tensioned. In other words, the previously described arrangement allows for suppression of lateral pivoting of the crampon spike 1.
