Definitions
- Snowboard binding with a base plate to be fastened on a board a support plate which can be fixed in an adjustable angular position relative to the base plate, a first coupling part arranged on the support plate, a second coupling part to be fastened to a shoe, which coupling parts by rotating the shoe by one to the plane of the Snowboards vertical axis between an initial position and an engagement position are movable, and with means for releasably locking the engagement position.
- Snowboard bindings primarily have the task of connecting the athlete's shoes with the snowboard. In addition, however, a whole series of other requirements are placed on snowboard bindings today.
- the angles of the longitudinal axes of both shoes with respect to the longitudinal axis of the board should be arbitrarily and independently adjustable, and the adjustment of these angles should be as simple as possible.
- the binding together with the shoe attached to it should have as little impact as possible on the elastic deformation of the board that occurs during the journey. This applies in particular to the bending of the board, but also to its twisting around the longitudinal axis.
- Such snowboard bindings are also required to be able to be coupled to and released from the boot simply and without great effort.
- Such snowboard bindings are known in various designs. In most cases, the above requirements are met by connecting two base plates to the snowboard independently and at a distance from each other, usually by screws.
- Another plate which carries the elements that hold the shoe, is detachably connected to each base plate, the base plate and the further plate having parts that can be brought into engagement with one another, for example in the form of a toothing.
- the shoe is formed by strap-like elements that cross over the front and rear areas of the sole captured.
- plate binding sometimes also called “hard binding”
- stiff soles as are common today in ski boots.
- the main disadvantage is that both the mutual distance of the bow-like elements and the position of the center of the shoe with respect to the board must be adapted to the shoe length of the user. This is particularly annoying when the athletes want to exchange their snowboards for a short time.
- the shoe must exert more or less pressure on the binding to get into plate bindings. This creates another disadvantage of this type of binding, namely that the board does not offer enough resistance to this pressure in soft and deep snow.
- a second group of snowboard bindings are the so-called "soft bindings", in which the user's shoe is held in a shell-like part by strap-like elements.
- a disadvantage of this group of bindings is that attaching and detaching the belt-like elements is perceived as tedious by many users, especially in cold weather, because it can hardly be done with gloves.
- the belt-like elements have a tendency to break, particularly when they are subjected to impacts, for example when a board that is deposited in a standing position falls over and falls onto the binding.
- a part is mounted on the sole of the shoe that can be engaged with a mechanism attached to the board.
- At least one strip-like part fastened in a recess of the shoe sole is held on two sides by members arranged on the binding, one of which is movable between an engaged position and a release position.
- the two links can either be arranged on the binding on both sides of the shoe or in the toe and heel area.
- the board In order for the pressure on the shoe to achieve the desired effect, the board has to resist this pressure, which is not always guaranteed in soft and deep snow. For the same reason, it is practically impossible for an athlete sitting on the floor to fix such a binding to the shoe without getting up. To release this binding, the movable member is brought into its release position, for example by a lever, after which the shoe can be lifted out of the binding.
- WO 94/21339 also relates to a snowboard binding belonging to the third of the groups mentioned. It has a sole plate to be fastened to the shoe, which carries a number of pins, each of which has a shaft and a head. A round plate is arranged on the snowboard, in which there is an arcuate slot for each pin, the width of which is smaller than the head but larger than the shaft of the pin. Each of the slots has an extension at its end into which the head of a pin fits. To get into this binding, the user must position the shoe so that the heads of the pins reach through the extended area of the slots.
- a common disadvantage of the latter two bindings is the relatively precise positioning of the shoe that is required when boarding.
- the longitudinal axis of the shoe must be brought into a certain angular position with respect to the longitudinal axis of the binding, and the starting position for locking the binding must be found at the same time.
- the sole In the binding according to EP A1 0 712 646, the sole must additionally be inclined in relation to the surface of the board in such a way that the said first end of the strip-like element can be gripped by the first of the said members.
- the sole is then again aligned parallel to the board surface, depending on the design, about an axis lying parallel or perpendicular to the longitudinal axis of the shoe.
- the starting position is reached when the heads of the pins are inserted into the enlarged areas of the slots in the round plate.
- the shoe sole should be aligned as parallel as possible to the board surface. Only then can the binding be engaged by turning the shoe.
- the position of the shoe relative to the snowboard must meet three conditions more or less simultaneously. It's easy to imagine that this is very difficult, especially on uneven ground and on a slope.
- Another disadvantage of both bindings is that snow and ice, which adhere to parts of the binding, can make it difficult or even impossible to get in. In such cases, the relevant parts must first be cleared of snow and ice, which is a tedious task, especially in deep snow.
- Another object of the invention is to propose a snowboard binding in which only a small amount of force and, accordingly, little counterforce from the snowboard is required for the latching movement.
- Another object of the invention is to design a snowboard binding in such a way that its functionality is not impaired by snow and ice, or that snow and ice, which adhere to the binding, are displaced when getting in.
- the object of the invention is to propose a snowboard binding whose parts to be fastened to the shoe can be attached in such a way that they do not disturb or endanger the user when walking.
- the snowboard binding according to the invention solves these tasks in that the first coupling part has cam-like elements which interact in the engagement position with hook-like elements arranged on the second coupling part, and on the first coupling part between the cam-like elements there is a support element on which the second The coupling part can be supported in such a way that it can be tilted in at least one direction in the starting position, and that control surfaces are present on the first coupling part, which cooperate with the hook-like elements in such a way that the second coupling part is rotated against the first one by a starting rotary movement Coupling part is clamped and fixable.
- the support element which allows the second coupling part to tilt in at least one direction, there is practically line contact between the coupling parts or preferably at least approximately point contact, as a result of which snow and ice, which may be present between the coupling parts when entering, are subject to high pressure exposed and thereby displaced.
- the tilting movement that is possible in the starting position around this line of contact or this point of contact supports the displacement of snow and ice.
- a point contact is also achieved if the shoe sole is not exactly parallel to the plane of the Boards is brought into the starting position.
- the interacting coupling parts can be designed so that there is a lot of play between them in the starting position, which makes this starting position easy for the user to hit. This play and the fact that practically no pressure is required on the board for the rotating latching movement make it possible to get into the binding even on uneven ground and in soft and deep snow or in a sitting position.
- the support element is a convexly curved surface of the first coupling part, as a result of which the second coupling part can be supported on the first coupling part in a tiltable manner.
- the support element can consist of at least one part protruding beyond the first coupling part, for example a pin inserted in the coupling part, or it can be designed as an elongated elevation projecting beyond the first coupling part.
- three cam-like elements are provided. This makes it easy to center the coupling parts together in the engagement position.
- the first coupling part has a substantially frustoconical base body, there is a lot of play during the approach of the coupling parts between this base body and the hook-like elements, which makes it even easier to bring the coupling parts into the starting position. Due to the fact that, according to a further embodiment, a screw received in a central threaded bushing of the base plate passes through the first coupling part eccentrically, this and with it the second coupling part is displaced against the heel, that is to say in an area of the sole in which there is more space than in the bale area.
- Means for locking two locking levers each pivotable about an axis, which can be pivoted simultaneously by means of a pivotable release lever. This further simplifies the use of the binding, because not only getting in, but also swiveling both locking levers out, can also be done by turning the shoe clockwise or counterclockwise.

- Figure 9 is a perspective view of the means for locking the engaged position
- Figure 10 is a perspective view of another embodiment of the two coupling parts.
- the base plate 1 shown in FIG. 1, for example made of cast aluminum, is fastened to the board with screws which extend through the holes denoted by 3.
- the holes are designed as elongated holes so that the position of the base plate on the board can be adjusted.
- a threaded bushing 5 (FIG. 8) is received in an opening 4 in the center of the base plate. Since very large forces are transmitted via this threaded bushing, the material of the base plate surrounding the threaded bushing is solidified when the base plate is manufactured by first forming a projecting collar around the opening 4 and then pressing it flat.
- the outer circumference 6 of the base plate 1 encloses an angle of 55 ° with the horizontal and has a toothing which is continued on the upper surface in an annular region 7.
- FIG. 2 shows the above the base plate 1, preferably also made of cast aluminum, which has the task of supporting other parts of the binding so that the angular position of the user's shoe with respect to the longitudinal axis of the board is adjustable.
- the support plate On its underside (not visible in the figure), the support plate has a toothing that fits onto the toothing 6, 7 of the base plate 1. In order to adjust the angular position, one only has to loosen the screw reaching through the central opening 9 a little, lift the support plate together with the elements attached to it, twist it and tighten the central screw again.
- the support plate 8 only needs to be raised for adjustment by an amount which is less than the thickness of the base plate.
- the edge 12 of the support plate overlaps the damping plate 14 described below, the bulges 13 formed on the edge preventing the damping plate from rotating about the support plate.
- Figure 3 shows the damping plate 14, which consists of plastic and can be produced for example by injection molding. It is primarily used to transmit forces between the user's shoe and the board, but also to dampen vibrations that occur while driving. So that the above-mentioned elastic deformation of the board is not hindered by the damping plate, the latter is not connected to the surface of the board, but is only held on the board by the edge 12 of the support plate 8. The edge 12 of the support plate with the bulges 13 fits into the annular region 15 and the depressions 16 of the damping plate.
- the surface of the damping plate is structured, on the one hand as anti-slip protection, on the other hand to make it easier for snow lying on the damping plate to be pushed out of the area between the shoe and the damping plate or scraped off the shoe sole when the shoe is latched in.
- An additional mechanical connection can be provided between the support plate 8 and the damping plate 14, so that these two parts can be assembled and disassembled as a unit and so that the damping plate easily follows an angular adjustment of the support plate.
- the roller plate 17 shown in perspective in FIGS. 4 and 5 is fastened by two screws projecting from below through holes 10 in the support plate 8 into the threaded holes 19.
- a third screw 11 extends from above through the opening 18 of the roller plate into the threaded bushing 5 (FIG. 8), which is received in the center of the base plate 1.
- the roller plate forms one of the two mutually engageable coupling parts of the binding and is so named because it has a convex curved surface 20 as a supporting element on which the coupling part interacting with it, namely the bracket described below, until the bracket is reached Can roll the engagement position. Due to this curved design of the surface, the contact zone between the roller plate and the underside of the bracket is almost punctiform. Such a contact zone, which allows the second coupling element to tilt in at least one direction, could also be formed by a different design of the support element, for example by at least one hump-like elevation or by one or more inserted pins. Since very large forces act on parts of the roller plate during travel, it is preferably made of forged steel.
- each cam has control surfaces 25a to 25e, the function of which will be described later.
- recesses 26 which serve two functions. On the one hand, they serve to save weight, on the other hand, these recesses reduce the curved surface, which can come into contact with the bracket. This makes it easier to to replace existing snow when entering the binding. If an ice layer has settled on the roller plate or on the underside of the bracket, this is exposed to great pressure in the contact zone, which is additionally reduced by the recesses, as a result of which it breaks and is also displaced.
- the bracket 28 mentioned is shown in perspective in FIG. It is fastened in a recess in the shoe sole in a manner not shown. This attachment can be done by screws, rivets, straps or in any other way.
- three hooks 29 are formed, which engage around the cams 24 of the roller plate 17 in the engagement position of the binding.
- Each hook has a back part 31 which extends essentially vertically downwards from the flat part 30 of the bracket and then has a leg part 32 which extends inwards essentially parallel to the flat part.
- At least the edge 33 of the back part 31 pointing forward in the viewing direction of the user is bent as shown in Figure 6, which reduces the risk that the hook 29 gets stuck on objects such as cables, gratings, floor mats and the like when walking.
- the arch could also be convex.
- FIG. 7 shows the two coupling parts 17 and 28 in a position which they can assume when the user brings his foot into the starting position in a tilted position. From this unfavorable position, too, the bracket 28 is not blocked by a rotational movement of the foot, but rather is brought into the engagement position by the control surfaces 25a to 25e. As can be clearly seen in the figure, the leg part 32 will abut the control surface 25b, for example, when the bracket is rotated clockwise, as a result of which the bracket is pulled against the roller plate and at the same time aligned parallel to it.
- FIG. 8 shows in longitudinal section the sole 35 of a boot fastened to a snowboard 38 by means of a snowboard binding according to the invention.
- the parts belonging to the locking mechanism are omitted in this figure.
- the depth of the Take 36 in the shoe sole 35 selected so that the bracket 30 does not protrude beyond the sole surface and thus does not hinder walking on a flat surface.
- the dimensions are selected so that in the engagement position of the binding when the shoe is unloaded, there is a small play 37 between the shoe sole and the damping plate 14, so that the rotational movements during engagement and release are not impeded by friction between the sole and the damping plate.
- the locking mechanism shown in FIG. 9, designated as a whole by 40, contains two mirror-symmetrically designed locking levers, designated 41 and 43, pivotable about axes 42 and 44, and a release lever 49, which is pivotable about an axis 50.
- the locking lever and the release lever are held by springs 45, 52 in the position shown in the figure.
- the area between the two locking levers lies below the cam 24 of the roller plate 17 and is intended to accommodate the leg part 32 of the hook 29 arranged on the front of the bracket 28 between them.
- the leg part of the hook first hits the outer surface 46 of the one locking lever, as a result of which it is forced inward against the force of the spring 45 and the path to the area between the two Releases locking levers.
- the bracket can then be rotated further until the leg with a side surface on the inner surface 48 of the other locking lever strikes.
- the other side surface of the leg has passed the outer edge 47 of the outer surface 46 of one locking lever, the locking lever 41 snaps back into its starting position and the leg 29 of the hook 29 is clamped between the two locking levers 41 and 43. Due to the symmetrical construction of the locking lever, the latching movement just described can take place exactly the same way from the other side, by first pushing the other locking lever inward through the leg part.
- the actuating end 53 of the release lever 49 is guided next to the damping plate 14 all the way down to the level of the board in order to avoid injuries or clothes getting caught.
- a plastic part 54 is attached to this actuating end 53 so that the surface of the board is not scratched by the release lever.
- the release lever is pulled backwards by the user against the force of the spring 52, that is to say in the direction of the heel. With this movement, the substantially T-shaped central region 55 of the release lever takes both locking levers at the same time and pivots them inward, so that the leg part 32 of the hook of the bracket is released. The user can then turn his or her foot clockwise or counterclockwise as required and thereby loosen the bracket attached to the shoe from the roller plate.
- the release levers of the two bindings can be directed inwards with respect to the user's feet, on the one hand because they are easier to reach there by hand, and on the other hand it makes it possible for the release lever of the second binding to be released by the shoe released from the first binding to be operated by sliding it along the inside of the other shoe from front to back over the board.
- a pin 51 serving as a stop is fastened in the support plate.
- the flat part 30 of the bracket is in contact with the curved surface 20 of the roller plate and can carry out the aforementioned tilting movement.
- the latching movement can begin, in which the user turns his shoe in the direction of the longitudinal axis of the damping plate.
- one of the leg parts 32 of the hooks 29 first comes into contact with one of the control surfaces, either with the control surface 25a (FIG. 5) or with the control surface 25b and is guided through it against the board.
- the bracket 28 begins to align parallel with the support plate 8, whereby the other two legs are also guided against the corresponding control surfaces of the associated cams.
- the inner surfaces 34 (FIG.
- the above-described embodiment of the snowboard binding leaves the user free to carry out the rotating latching movement and also the release movement both clockwise and counterclockwise.
- FIG. 10 shows the two coupling parts 117 and 128 in a perspective view.
- Two cam-like elements 124 and 124a can be seen on the roller plate 117, with which the hook-like elements 129 and 129a interact, as will be described below, between the two a support element 120 is arranged, which in this example is designed as an elongate elevation.
- the two ends of the support element are slightly raised in relation to its central region and form two points of contact with the second coupling part 128, so that the second coupling part can tilt in one direction about the connecting axis of these points in the starting position.
- the support element could also consist of one or two pins inserted into the roller plate, or, as in the first exemplary embodiment, of a curved surface. Of the control surfaces present on the first coupling part, only the control surfaces 125a and 125e are visible in this figure.
- the user When getting into this binding, the user will bring his foot from the front to the back of the roller plate such that the plate part 130 rests on the support element 120 and the leg part 132 is guided into the position indicated by the dash-dotted lines by the corresponding control surfaces becomes.
- the movement of the foot automatically changes into a rotational movement, the axis of rotation 170 of which extends through the hook-like element 129a.
- the other hook-like element 129 is guided along the control surfaces 125a and 125e, pushing the locking cam 161 of the single locking lever 160 inwards.
- the control cam jumps out again due to the force of the spring 162 and the binding is locked.
- the locking lever 160 also forms the release lever. If it is pivoted counterclockwise, the locking cam 161 clears the way to be able to release the shoe from the binding by rotating the foot clockwise - again about the axis 170.
