Description

Snowshoe TECHNICAL FIELD OF THE INVENTION

[0001] The present invention relates to a snowshoe comprising a basic structure forming a boot area and a support area. The support area includes a lateral overhang on each side of the boot area and extends towards the rear of the boot area to form a rear tip. The snowshoe exhibits advantageous characteristics of flexibility and ergonomics. STATE OF PRIOR ART

[0002] Snowshoes have been around for many years. They were originally designed to allow people to move across terrain covered in deep snow. They are also very common in Nordic countries, which frequently experience heavy snowfall. However, these extreme conditions are increasingly less representative of how snowshoes are used today. In fact, nowadays they are primarily used for sport and leisure by hikers. Since snowshoe enthusiasts vary greatly in skill level, from beginners to expert hikers, the requirements of each level are very different. This diversity compels manufacturers to constantly develop new products to best meet these varied expectations. As a result, several product lines are now available, each with its own specific advantages.But manufacturers are still looking for innovative solutions that can provide greater comfort and improved dynamic performance.

[0003] Generally speaking, snowshoes consist of a deck, a front tip, a rear section, and a binding system. The basic configuration allows for easy movement on snow due to increased flotation, preventing sinking into the snow.

[0004] The front and rear spatulae are designed to allow for an easy gait, with a natural foot roll, facilitating walking and making it more comfortable. However, this objective is generally not achieved due to the bulk of the snowshoes; their shape, the shoe support, and their surface often make them difficult to maneuver. Thus, in use, the snowshoer's gait is often arduous, as the walker must lift the front of the snowshoe, pull it forward, and then set it flat, without being able to perform a natural and ergonomic foot roll. These constraints mean that the vast majority of users quickly show signs of fatigue and / or discomfort, even after a short hike.

[0005] Many users only use snowshoes occasionally, for example, during a stay at a winter resort. In these cases, snowshoes are rented from specialized shops. To meet profitability requirements, rental companies want to keep the equipment for as long as possible and demand very robust and durable products from manufacturers. In response to these requirements, manufacturers offer snowshoes with a rigid frame.

[0006] This design presents several drawbacks. First, the lack of flexibility makes snowshoes unergonomic. A rigid snowshoe doesn't conform to the shape of the shoe or the surface on which it's placed. Second, the materials used are selected primarily to meet the requirements of lightness, durability, and rigidity. These types of materials generally offer weak, or even poor, traction. To overcome these limitations, many snowshoes are equipped with metal inserts designed to increase grip on snow or ice. This feature is practical for these types of terrain, but users may encounter hard surfaces, such as when crossing a road, where snowshoes are no longer suitable.

[0007] Finally, to compensate for the snowshoe's rigidity and facilitate walking, snowshoes are equipped with either a hinge or a double-bladed design, meaning one blade at the front of the foot and another at the back, or a very raised front blade combined with a relatively flat rear section. These features allow the user to have a more natural gait than with completely flat snowshoes. However, the raised front blades require the user to lift their foot relatively high, which demands additional effort with each step. Without this unnatural movement, the front blade can strike an obstacle and / or catch on the ground, causing a fall. Furthermore, because the feet have a slight angle of inward rotation, the rear blades can interfere with each other while walking. If they become stuck together, there is a risk of falling.

[0008] The shoes are fixed to a hinged support connected to the frame to facilitate foot pivoting during walking. This hinge generates noise. The rigid joints restrict the flexibility of both the shoes and the foot. These supports are not suitable for walking on uneven terrain. The lack of deformation of the support and the frame results in a non-vertical foot placement, which becomes misaligned with the lower limb. These movements can lead to pathologies.

[0009] Various documents illustrate the different types of snowshoes available, which present the aforementioned disadvantages.

[0010] For example, document FR2912928 describes a snowshoe with a front tip, a rear section, and a deck. The foot is secured to the snowshoe by the front of the boot so that the back of the foot is mobile. A pivoting mounting plate with a hinge is attached to the deck frame. This design allows the foot to pivot on the snowshoe. A lateral hinge is also included. These features They allow for a more natural foot roll. But the architecture is complex and expensive to implement.

[0011] US patent 6006453 describes a snowshoe with a front tip and a rear section, and a frame formed by rails. The foot is attached to the snowshoe only by the front of the boot. The tips are interchangeable, and several sizes are available by adjusting the rail extension to accommodate the intended use and the user's shoe size. Despite this design, the presence of the front tip forces the user to lift their feet relatively high while walking, leading to premature fatigue.

[0012] Asymmetrical snowshoes are also known. For example, document FR2560055 describes asymmetrical snowshoes with multi-size, articulated, offset, and off-center bindings, allowing for easy movement on varied snowy terrain. These snowshoes are characterized by their ease of use. The effort required by the user to move forward is considerably reduced thanks to the articulated binding system, the offset frame, the stabilizing wing, and the crampon. However, these snowshoes have the aforementioned drawbacks related to the presence of the front tip, which requires the user to lift their foot relatively high.

[0013] With the aim of improving comfort and grip, deformable snowshoes have been developed.

[0014] For example, document FR2768938 describes a racket with a head surrounded by a frame, the outline of which defines the bearing surface, and a support piece extending inside to which the user's shoe is attached. The frame's outline is open. More precisely, it has an opening providing a discontinuity between the outside and inside of the frame where the support piece is located. This opening is intended to make the parts of the frame on either side more flexible. Maximum flexibility is achieved at the opening. This feature allows the snowshoe frame to deform differently on either side of the opening, thus adapting to challenging terrain that doesn't define a single point of contact, resulting in improved grip. However, this snowshoe has the aforementioned drawbacks related to the presence of the front tip, requiring the user to lift their foot relatively high.

[0015] The US2010132225 document describes a snowshoe with a flexible binding interface, a front tip, and a rear section. The rear section is made of a softer material than the front. This feature allows the snowshoe to cushion the user's foot during walking, thus increasing comfort. Despite this, the snowshoe has the aforementioned drawbacks related to the presence of the front tip, requiring the user to lift their foot relatively high.

[0016] US2014041258 describes a snowshoe consisting of a long, wide deck, a front tip, and a rear section. The snowshoe is made of a flexible material incorporating a plurality of interlocking cone-shaped circles. These circles can deform under the user's weight to compensate for uneven terrain, ensuring good support and improved comfort. However, the snowshoe has the aforementioned drawbacks related to the front tip, requiring the user to lift their foot relatively high.

[0017] Following the evolution of deformable rackets, flexible rackets have been developed.

[0018] For example, document FR2999446 describes a racket in the form of an elongated plate called a "mesh" on which is mounted a binding designed to hold the user's shoe, the binding being of the pivoting type around a transverse axis (X, X'), said "mesh" comprising a part The central area, located within the space occupied by the shoe, extends forward beyond the pivot point (X, X') with a forward portion called the spatula, which curves upwards, and backward beyond the central portion with a rear portion called the heel. The deck is flexible, at least longitudinally and at least in the central portion. The snowshoe also presents the aforementioned disadvantages related to the presence of the front spatula, requiring the user to lift their foot relatively high.

[0019] Document W09506502 describes a snowshoe consisting of a semi-flexible platform with connecting means for attaching the heel and front of the user's shoe to the platform. The platform is molded from a semi-flexible plastic material capable of flexing during walking. This characteristic makes the snowshoe slightly flexible, but not sufficiently so for real comfort during the foot's roll. The snowshoe also has the aforementioned drawbacks related to the presence of the front tip, which forces the user to lift their foot relatively high.

[0020] Document FR2743501 describes a snowshoe, particularly for use on snow, consisting of a substantially flat platform equipped with reversible fastening elements for attaching the user's foot to said platform, made of cellular elastomer. This snowshoe is lightweight, rigid, but with a degree of elasticity. This characteristic allows the user to have a more comfortable snowshoe than traditional snowshoes. However, the snowshoe has the aforementioned drawbacks related to the presence of the front tip, which requires the user to lift their foot relatively high.

[0021] The US standard S20170225061 describes a substantially flat snowshoe with a basic structure forming a boot area and a support zone surrounding the boot area, except at the front, where the binding placement causes the boot to extend beyond the front of the snowshoe. When walking, this allows the toes to catch on or interfere with any obstacle, increasing the risk of falls. potential. Furthermore, the natural progression of walking is not respected.

[0022] To overcome these various drawbacks, the invention provides for different technical means. DESCRIPTION OF THE INVENTION

[0023] Firstly, a primary objective of the invention is to provide a flexible and ergonomic snowshoe.

[0024] Another objective of the invention is to provide a snowshoe with good range and optimal grip on all types of ground and varied terrain.

[0025] Yet another objective of the invention is to provide a snowshoe of simple and inexpensive design.

[0026] Finally, another objective of the invention is to provide a snowshoe that facilitates walking and has the necessary characteristics to allow the user to have the most natural gait possible.

[0027] To achieve this, the invention provides for a snowshoe comprising a basic structure forming a shoe area and a bearing area, in which the bearing area includes a lateral overhang on each side of the shoe area, the front of the snowshoe ending with a front beak corresponding to the front of the shoe area and housing the front part of the shoe, and the basic structure being elastically deformable.

[0028] Thanks to these features, and in particular the fact that the front of the snowshoe and the front of the shoe area are aligned, ergonomics and comfort are optimized. Furthermore, the user uses the snowshoe in a normal walking motion, with a foot roll that respects the body's biomechanics, for enhanced comfort. Increased and improved performance. The racket also offers increased safety, particularly in preventing falls.

[0029] In an advantageous embodiment, the front portion of the snowshoe is raised. This arrangement, forming an upward-curving frontal area, helps to avoid friction and interference with the ground and potential obstacles while walking.

[0030] According to another advantageous embodiment, the basic structure includes a main reinforcing element having at least three substantially "T"-shaped sectors corresponding respectively with support areas A of the first metatarsal, B of the fifth metatarsal and C of the heel.

[0031] This feature allows for a snowshoe that is flexible enough to adapt to uneven terrain, yet rigid enough to provide good flotation and traction. The main reinforcement element transfers lateral pressure from the snowshoe to different areas of the foot when walking on slopes. These reinforcements are directed towards key ergonomic points on the foot. The main reinforcement is centered at the first metatarsal and extends to the inner end of the snowshoe to enhance propulsion when walking on slopes. Stabilization of the uphill foot when walking on slopes is ensured by reinforcement lines between the fifth metatarsal and the outer end of the snowshoe.

[0032] Advantageously, the basic structure includes a secondary reinforcement element with a lower level of rigidity than the primary reinforcement element, this secondary reinforcement element extending between the sectors of the primary reinforcement element. This arrangement provides a good level of load-bearing capacity while maintaining structural flexibility that promotes the ergonomics of the racket.

[0033] According to another advantageous embodiment, the basic structure also includes a comfort layer made of expanded or non-expanded material, covering all or part of the main reinforcement element.

[0034] This feature makes it possible to obtain a racket with a simple, comfortable, and inexpensive design.

[0035] Advantageously, the basic structure is elastically deformable. This characteristic allows for physiological gait, furthermore, by enabling an ergonomic and natural foot roll.

[0036] In an advantageous embodiment, the basic structure has a solid surface. The absence of sieves, holes, or perforations provides better load-bearing capacity and creates thermal insulation between the snow and the shoe.

[0037] Also advantageously, the snowshoe also features two lateral edges, arranged on either side of the shoe area.

[0038] These edges provide good lateral foot support thanks to the proper positioning of the boot on the snowshoe. The boot area may include crampons and / or a non-slip surface to improve support and prevent the foot from slipping on the snowshoe. This allows for better power transfer to the snowshoe and improves overall performance. These edges can also serve as a support for a binding system.

[0039] In an advantageous embodiment, the bearing area is curved, preferably on the lateral edges. This feature prevents snow from accumulating next to the boot and stiffens the snowshoe.

[0040] Advantageously, each of the lateral overhangs has a lower surface, said lower surface being raised on at least one of the two Lateral overhangs. This arrangement allows for better ergonomics, for example by reducing the risk of friction with the ground or potential obstacles, particularly when walking on flat ground.

[0041] According to an advantageous embodiment, the basic structure is made of thermoplastic material, preferably included in the list of the following families: thermoplastic polyurethane, thermoplastic elastomer such as polyethylene vinyl acetate or styrene butadiene styrene.

[0042] These materials withstand harsh operating environments, offer good resistance to wear (particularly from friction), and allow for a remarkably flexible and exceptionally lightweight structure. All these characteristics contribute to user comfort and enhance the user experience. The density of polyethylene vinyl acetate is approximately 0.1 to 0.2, and that of thermoplastic polyurethane or thermoplastic elastomer is approximately 0.4 to 0.8.

[0043] According to yet another advantageous embodiment, the material of the basic structure is expanded or not.

[0044] Advantageously, the rear of the shoe area is asymmetrical and preferably with a cutout freeing up the inner side. This design prevents interference between the two rear sections of the shoe area and facilitates walking, particularly at speed, where the risk of snowshoe collisions is higher.

[0045] Also advantageously, the rear of the shoe area is raised and / or twisted outwards and / or has an opening.

[0046] Such an arrangement, with a section that rises upwards, helps to avoid friction and interference with the ground and any potential obstacles. The section The raised design allows for a more ergonomic and natural foot roll. This arrangement helps to channel snow away to the sides, preventing it from being thrown up. The twisted structure also provides rigidity to the snowshoe. The optional opening also serves as a grip and / or attachment point.

[0047] According to an advantageous embodiment, a shoe is integrated into the shoe area. DESCRIPTION OF THE FIGURES

DETAILED DESCRIPTION OF THE INVENTION RACKET BODY AND BASIC STRUCTURE

[0049] Figures 1 to 6 illustrate, from various perspectives, an example of a snowshoe according to the invention. As clearly visible in Figures 1 and 3, the snowshoe 1 comprises a basic structure 2 including a shoe area 3 and a support area 4 surrounding the shoe area 3, except at the front of the shoe area, where the snowshoe terminates in a frontal portion 7. This frontal portion includes a front beak 8 corresponding substantially to the front of the shoe area 3. This results in a snowshoe without a front tip, significantly improving ergonomics and walking comfort. Furthermore, the user can use their snowshoes by walking in a manner similar to normal walking with shoes, by rolling the foot, that is, by placing the heel down first, then the ball of the foot, and finally the forefoot. The rolling motion then continues with the lifting of the heel and ends with propulsion at the toes.As illustrated, the front beak 8 is advantageously curved, forming a kind of protective shell for the front end of the shoe.

[0050] On each side of the shoe area 3, the support zone 4 includes a lateral overhang 5. At the rear, the support zone 2 extends beyond the shoe area 3 to form the back of the shoe area 3. As clearly visible in Figure 1, the basic structure has a solid surface. The support zone 4 thus provides an optimal weight distribution effect, minimizing sinking in the snow and ensuring a well-balanced gait. The continuous surface also provides good thermal insulation, protecting the feet from cold and dampness.

[0051] To further enhance ergonomics, ease of use, and comfort, the base structure 2 is preferably made from an elastically deformable material, giving it great flexibility. The deformability of the base structure allows the rear spatula to flex under the walker's weight as they bring their heel to the ground and place it down. The snowshoe's flexibility also optimizes ergonomic behavior, in accordance with and respecting the biomechanics of the foot, which results in a gait with a rolling motion of the foot, as previously mentioned.

[0052] Figure 5 and Figures 7a to 7g illustrate the shaping of the load-bearing area 4 in a curved manner, preferably on the lateral overhangs 5. The lateral overhangs can thus be made according to various types of profiles, such as rectangular (Figure 7a), with inclined external walls (Figure 7b), in arc of a circle (Figure 7c), flat (Figure 7d), inclined outwards (Figure 7e), or inwards (Figure 7f), or even in the shape of a "V" (Figure 7g).

[0053] Each of the lateral overhangs 5 ​​has a lower surface 16, said lower surface 16 being raised on at least one of the two lateral overhangs 5, as shown in the examples in Figures 7d, 7e, 7f and 7g. The lateral overhangs are sufficiently flexible to conform to various obstacles in the terrain such as holes, stones, or other features.

[0054] The basic structure 2 is advantageously made of a thermoplastic material, preferably from the following families: thermoplastic polyurethane, thermoplastic elastomer. Polyethylene vinyl acetate or styrene butadiene styrene are advantageously used. The material of the basic structure 2 can be expanded or unexpanded, depending on the application.

[0055] As shown in the example in Figure 1, the rear of the shoe area 3 is preferably asymmetrical and advantageously includes a clearance 15 freeing the inner side.

[0056] As shown in Figure 6, the rear of the shoe area 3 is raised and / or twisted outwards. It preferably includes an opening 19. REINFORCEMENT STRUCTURE

[0057] According to an advantageous embodiment, to prevent the snowshoe from being too flexible, and generating little or no lift, the basic structure 2 includes a main reinforcement element 20 designed to provide sufficient rigidity so that the weight transfer of the walker is well distributed over the entire surface of the snowshoe.

[0058] As illustrated in Figures 8, 9 and Figure 10, the main reinforcing element 20 comprises at least three sectors 21, 22, 23 corresponding respectively with support areas A of the first metatarsal, B of the fifth metatarsal and C of the heel.

[0059] The main reinforcement element 20 is designed to transmit any stresses that may be received by sectors 21, 22, 23 to the rest of the basic structure 2.

[0060] As shown in the example in Figure 8a, the main reinforcing element 20 has, for example, a profile substantially in the shape of a "T".

[0061] Sectors 21 and 22 can extend into adjacent lateral overhang zones 5. Similarly, the heel sector 23 can also extend into the lateral overhang zone 5 towards the rear of the heel and / or on either side of it.

[0062] To obtain the continuous (or open-ended) structure of the load-bearing zone 4 and to help distribute the user's weight, the basic structure 2 includes a secondary reinforcement element 30. This secondary reinforcement element has a lower level of rigidity than the main reinforcement element 20.

[0063] The secondary reinforcement element 30 is arranged between sectors 21, 22, 23 of the main reinforcement element 20.

[0064] To improve comfort, the basic structure 2 also includes a comfort layer 40 made of expanded or non-expanded foam, covering all or part of the main reinforcement element 20, as shown in the examples of figures 11a, 11b and 11c, in median axial section in figure 11a, and at different longitudinal positions of the racket for figures 11b and 11c. A thermoplastic material is used for example to make the comfort layer.

[0065] As shown for example in figures 2 to 5, two lateral edges 9 are arranged on either side of the shoe area 3. The lateral edges 9 are preferably made of material with the basic structure 2, for maximum robustness.

[0066] As illustrated in the embodiment examples in Figures 8, 9 and 10, the main reinforcement may also include a cubo-scaphoidal sector 24, 25, which extends substantially between the bearing areas of the scaphoid and the cuboid.

[0067] In the example in Figure 10, the cubo-scaphoidal zone 24, 25 extends on either side into the zone of the adjacent lateral overhangs 5.

[0068] Also in the embodiment example of Figure 10, the main reinforcement element includes a cuboid-5th metatarsal axis extending substantially between the bearing areas of the cuboid 24 and the 5th metatarsal 22.

[0069] Figure 10 also illustrates that the main reinforcement element can include lateral sectors 26, 27 extending over at least a portion of each of the lateral overhangs 5. Alternatively, these lateral sectors 26, 27 are connected to each other.

[0070] According to yet another embodiment, the reinforcement structure described above can be used on one or more other types of rackets, for similar functions. FIXING SYSTEM

[0071] According to yet another advantageous embodiment, as shown in figures 2 to 6, the racket includes a shaft cover 10 extending longitudinally from said front beak 8 to the instep and laterally between each of the lateral edges 9. The shaft cover with the front beak 8 and the lateral edges 9 form a forefoot housing 6, adapted to accommodate the front part of the shoe.

[0072] Considering the racket in the axial direction, that is to say lengthwise, the upper cover 10 is preferably made of a single piece covering the shoe from the front beak 8 to the instep. This single piece is generally elastic, either with an elastic material or with elastic zones.

[0073] To implement this elasticity, it is anticipated, for example, that the Elastic material is an elastic fabric, preferably substantially waterproof. According to various embodiments, the fabric may, for example, have meshes oriented at approximately 45° to the longitudinal axis of the racket, or one or more mesh areas oriented at approximately 90° to the longitudinal axis of the racket. In another embodiment, the fabric is expanded and preferably contains neoprene.

[0074] Considering the racket in the transverse direction, or perpendicular to the axial direction, the stem cover 10 covers the entire surface between the front beak 8 on one side, and at least one of the lateral edges 9 on the other. In the embodiment shown in Figures 2 and 3, a fastening element 18, such as a lace, strap, or belt, cooperates with the stem cover 10.

[0075] An anti-recoil element 13, fixed for example on the lateral edges 9 and adapted to surround at least partially the back of the shoe, is illustrated in the examples of figures 2 to 6. Such a tightening element 18 can be coupled to one or more blockers 14, as shown in the example of figure 2.

[0076] According to various potential embodiments, the stem cover 10 is made in a removable manner, and / or extends to form a gaiter made of the same material as said stem cover 10. In another variant, the stem cover 10 and the front beak 8 are one piece.

[0077] According to yet another embodiment, the previously described fastening system can be used on one or more other types of snowshoes, for similar functions. Reference numbers used in the figures
