Definitions
- the field of the invention is that of devices for the practice of snow sliding sports and more particularly that of snowboards which can be separated into two bodies and which can be used as an aid to climbing the snow. Similar to hiking skis using separate bodies. Such boards are generally better known by the term "splitboard" (in English).
- the present invention relates more precisely to a surfboard for the practice of sliding snow sports and a method of transforming such a board into a board, called "splitboard", adapted to be used both as a board classic surfing and hiking skis by separating the board into two distinct slippery bodies.
- this second alternative requires many tools (hacksaw, drill, circular saw, greenhouse joints, etc.), serious manual and technical skills to make the cuts with a circular saw, but also to make the holes for the hooks and other necessary fastening systems, additions of resin or plastic, sanding, etc. Thus, it takes not less than thirty successive operations to cut and transform a standard board into a "splitboard".
- This second solution although attractive on paper for practitioners, is difficult to implement by a single individual and the transformation is often aborted for lack of time or does not give full satisfaction for lack of technical skills and / or manual on the part of the user.
- the invention aims to provide a board for the practice of sliding on snow and a method of transformation to solve the aforementioned problems.
- the board according to the invention has the advantage of simplifying the transformation by a particular of a standard board (not pre-cut in the factory) into a board called "splitboard" allowing the combined practice of ski touring and snowboarding.
- the invention aims to protect a board for the practice of sliding on snow formed by a sandwich structure comprising a core formed by a first portion and a second distinct portion extending in the longitudinal direction of said board; said board having a central member positioned between the first portion and the second portion of said core formed by two independent pieces; said board being characterized in that said independent parts are secured together non-permanently by connecting means ensuring a reversible holding and positioning of the two independent parts, said connecting means ensuring a seal of the connection against the insertion of resin during the manufacture of said board.
- the snowboard proposed by the invention is a snowboard of standard construction having the particularity of predisposing a separate core into two distinct parts (ie not integral) so as to facilitate a transformation into a board called "splitboard" ".
- the board according to the invention may also have one or more of the following characteristics considered individually or in any technically possible combination: said central element is positioned at the median plane of said board;
- said central element is made of polymer material or of composite material; each of the two independent parts of said central element is integral with a part constituting the core;
- the reversible connection means are formed by an adhesive layer for temporarily and reversibly maintain the two parts;
- the reversible connection means are made by magnetization of the two parts of the central element
- the two pieces of the central element are made from a magnetic powder or a permanent magnet and a thermoplastic or thermally bondable binder;
- the two pieces of the central element are separated by an anti-polymerization layer intended to prevent the permanent adhesion of the two parts during the manufacture of said board.
- the invention also relates to a method of transforming said board according to one of the preceding claims into a board divided into two parts for the combined practice of ski touring and snowboarding, said board having a sandwich structure formed by a core constituted by two distinct parts, lower and upper skins situated on either side of said cores in the direction of the thickness, a sole and an upper outer layer, said method of transformation comprising the steps of:
- the transformation method according to the invention may also have one or more of the following characteristics, considered individually or in any technically possible combination:
- a cutting tool for example a cutting tool such as a cutter or a knife;
- the step of separating the two parts forming the core consists of a step of breaking the layer separating the two pieces forming the central element
- the method comprises a step of assembling fastening means for reversibly securing and separating the two cut portions of said board.
- FIG. 1 shows a cross-sectional view of a first embodiment of a snowboard according to the invention
- FIG. 2 represents a cross-sectional view of a second embodiment of the center piece of the snowboard shown in FIG. 1;
- FIG. 3 represents a cross-sectional view of a third embodiment of the snowboard shown in FIG. 1;
- FIG. 4 represents a cross-sectional view of a fourth embodiment of the snowboard shown in FIG. 1.
- Figure 1 shows a sectional view along the cross section of a first embodiment of a snowboard 100 according to the invention.
- the snowboard 100 or snowboard, consists of a sandwich structure formed by a succession of layers.
- the sandwich structure of the snowboard 100 is conventionally composed of:
- lower skins 121 and upper 122 respectively covering the lower surface and the upper surface of the core 1 and protecting it from all external elements that may damage it, in particular water;
- the lower skin 121 and upper 122 provide the rigidity necessary for snowboard 100 and are conventionally composed of fibers and resin:
- a sole 150 intended to be in contact with the snow and allowing the glide of the surf;
- an upper face 1 60 guaranteeing the upper protection of the sandwich structure sensitive to water
- - 170 inserts for screwing bindings for the practice of classic alpine surfing but also for the practice of ski touring.
- the snowboard 100 called board in the following description, has the distinction of having a core 1 10 in two separate parts. According to the first embodiment illustrated in FIG.
- (1 10) is formed by two pieces thus forming two half-cores 1 1 1 and 1 12 extending longitudinally along the longitudinal axis of the board 100, at the median plane of the board.
- the half-cores 11 1, 1 12 are preferably made of wood, but it is also envisaged to make the two half-cores polyurethane foam or all types of materials conventionally used in the construction of a snowboard or of equipment for the practice of sliding sports on snow.
- the board 100 according to the invention also comprises in its center, and positioned between the two half-cores 1 1 1, 1 12, a central element 180 made of polymer, advantageously ABS (for Acrylonitrile-Butadiene-Styrene) or in elastomer or rubber material.
- polymer advantageously ABS (for Acrylonitrile-Butadiene-Styrene) or in elastomer or rubber material.
- ABS for Acrylonitrile-Butadiene-Styrene
- polymer is meant both natural polymers and synthetic or artificial polymers as well as polymer blends.
- the central element 180 may also be formed by a composite part combining different mechanical, chemical, etc. properties of different materials.
- the central element 180 may be formed by the combination of different polymeric materials, for example an ABS part in contact with the cores and a polyethylene central part or by the combination of a polymer material (for example rubber for example) and a plant tissue (for example cork).
- the central element 180 can also be made from wood species advantageously having a natural resistance to moisture.
- this central wooden element is not intended to take over the constraints of the core.
- this central polymer element 180 consists of two independent pieces 181, 182 of substantially rectangular shape and extending over the entire length of the board 100 on either side of the median plane of 100.
- the two pieces may have different shapes depending on the design of the board and the type of desired cutting profile. Examples of embodiments will be described later, in particular in Figures 4 and 5.
- the two parts 181, 182 are held fast, non-permanently and reversibly, by specific connecting means.
- These connecting means are for example made by temporary gluing (non-permanent) of the two pieces 181, 182 by means of an adhesive layer reversibly solidifying the two pieces 181, 182.
- the purpose of this adhesive layer is to to facilitate the positioning, to ensure a temporary maintenance of the two half-cores 1 1 1, 1 12 during the assembly of the board 100 and to avoid a resin insertion between the two parts 181, 182 during the manufacture of the board 100.
- layer is meant a physical layer, for example a sheet or a strip which is deposited between the two pieces of the central element, but also a thin layer sprayed from a liquid agent.
- the two parts 181, 182 of the central element 180 are held together, non-permanently and reversibly, by magnetic attraction of the two parts 181, 182.
- the two parts 181 , 182 are plasto-magnets, that is to say composite materials formed of a magnetic powder or a permanent magnet and a thermoplastic or thermally bondable binder.
- the manufacture of these plasto-magnets is by injection under pressure or by cold compression.
- the magnetic powders may be permanent magnet magnetic powder, for example based on neodymium, ferrite, iron or boron. The magnetization of these plasto-magnets is performed either during the molding of parts 181, 182 or after molding.
- the connecting means are dimensioned so that they generate a holding force sufficient to withstand the pressure of the resin exerted during the manufacture of the board , so as to avoid any introduction of resin between the two parts 181, 182 and therefore between the two cores while allowing manual tearing or detachment of the two half-cores without the use of specific tools.
- the two pieces 181, 182 constituting the central element 180 may also be separated by an additional layer 183, for example a polytetrafluoroethylene (PTFE) sheet or strip, intended to prevent any adhesion of the two polymer pieces 181, 182 during the resealing operation during the manufacture of the board 100 in the factory.
- PTFE polytetrafluoroethylene
- the central element 180 is also intended to advantageously form a protective element and a lateral reinforcing element at each half-core 1 1 1, 1 12 when the board according to the invention is divided into two parts so as to turn into a "splitboard".
- edges 140 positioned at the periphery of the board 100 are not joined at the level of the median plane of each end (i.e. at the nose and heel of the surf).
- the internal configuration of the board as described facilitates the transformation operation of a classic snowboard (ie monobloc) into a surfboard, called “splitboard” having two parts that it is possible to to use independently (mounted ski touring) or jointly reforming a snowboard for the descent via means provided for this purpose (not shown).
- a classic snowboard ie monobloc
- splitboard having two parts that it is possible to to use independently (mounted ski touring) or jointly reforming a snowboard for the descent via means provided for this purpose (not shown).
- the central element 180 separating the two half-cores 1 1 1, 1 12 may be of different materials and have different shapes as long as they make it easier to transform the board by the user and make it possible to perform a protection of the songs of the half-cores against external aggressions.
- Figures 2 to 5 show, in cross section, different designs of this central part 180.
- the central element 380 is formed by two parts 381, 382 extending over the entire length of the surf 100, on either side of the median plane of the surf 100.
- the two parts 381, 382 cooperate with each other by means of a link 384 type mortise-mortise.
- the tenon-mortise connection 384 advantageously makes it possible to stiffen the connection between the two parts 381, 382 of the central element 380.
- the tenon-mortise connection 384 is illustrated by way of example and other connections allowing the two parts 381, 382 to nest so as to stiffen the assembly are also envisaged.
- the two parts 381, 382 of the central element 380 may be separated by a layer 383, for example polytetrafluoroethylene (PTFE), intended to increase the seal of the connection by avoiding the introduction of resin at the bond and thus preventing the adhesion of the two parts 381, 382 during the resinsing operation.
- PTFE polytetrafluoroethylene
- the central element 480 is formed by two parts 481, 482 extending over the entire length of the surf 100 and having an oblique contact surface (ie non-normal with respect to the upper or lower surface of central element 480).
- the two parts 481, 482 of the central element 480 can be separated by a layer 483. intended to increase the sealing of the connection by avoiding the introduction of resin at the bond and thus preventing the adhesion of the two parts 481, 482 during the resin.
- the central element 580 is formed by two pieces 581, 582 extending over the entire length of the surf 100 and having a contact surface curved either in the longitudinal plane of the board 100 as shown, either in the transverse plane of the board 100 (not shown).
- the surfboard according to the invention has an internal structure allowing the practice of snowboarding on piste or off-piste in a conventional manner, and has predispositions in its internal structure to facilitate the separation of the board in two parties in order to use it in combination for the practice of ski touring and snowboarding.
- a user conventionally using the surfboard as presented above can decide, for example when it is at the end of life, to make a "splitboard" type board from this particular board that it has already.
- the transformation operation by the user becomes extremely simple. Indeed, the user can by means of a simple cutting tool, such as a knife or a cutter, and a guide rule cut surf in minutes and without the need for specific tools or special technical knowledge.
- a simple cutting tool such as a knife or a cutter
- a guide rule cut surf in minutes and without the need for specific tools or special technical knowledge.
- this step can be further facilitated by presence of a visual means or by the presence of a physical guide, such as a groove, provided on the upper face 1 60 from the design of the board 100;
- the separation may consist if necessary in a breaking step of the adhesive layer now together the two parts of the central element.
- the cutting of the board can be performed in a rectilinear manner, at the median plane or not, as described above or in a different profile, for example in a curved profile or a zigzag profile.
- the two half-cores and / or the central element will have suitable shapes to achieve such a cut.
- a sixth embodiment more economical, it is possible to overcome the positioning of a central element between the two half-cores.
- the two half-cores are then separated by an adhesive layer or by a layer that makes it possible to avoid the polymerization of the resin at the junction plane of the two half-cores.
- the user will have to carry out an additional step, during the transformation of his board into a "splitboard" type board, consisting of protecting the edges of the two half-cores cut out, for example by the application a protective stain protecting the half-cores from moisture.
- the structure of the board according to the invention it is possible to incorporate at the factory manufacturing inserts for fastening bindings for the combined practice of ski touring and snowboard whose standards of attachment are different from the hull setting standards for snowboarding. This is made possible by mastering the cutting and the distance between the inserts once the two sliding bodies reassembled.
- the method of separation described in the patent and the advantageous structure of the board allow to maintain an identical spacing of the inserts between the one-piece board (ie without transformation) and the board reassembled in surf after transformation into "splitboard", which this type of insert can be positioned at the factory, which is not possible with traditional methods of transformation.
- a cutting tool such as a saw
- a blade whose thickness is variable and not known when of the realization of the board, which would vary the inter-inserts space and would not allow the positioning and screwing of the fasteners.
- the invention and the method of separation of the board the user is freed from the use of a cutting tool, the thickness of the blade is not controlled and may vary depending on the size of the board. cutting tool used.
- the invention has been particularly described for snowboarding; however, the invention is also applicable to a monoski which also forms a single board on which both feet are fixed and whose internal structure is similar to a snowboard.
