Abstract

One of the preferred features of ski (1) is that it would have without any considerable impact on other general mechanical properties of the ski (1) as such either during the production phase or even later the option of integrating the assembly for positioning of the ski binding components (31, 32) in such a way that the forces from the area of the ski binding would be as directly as possible transferred to the area beneath the neutral bending axis (O) of the ski (1), in particular into the direct vicinity of the edges (12, 13) along the sliding surface (11) of the ski (1). According to the invention this can be achieved thanks to the application of the specifically for this purpose designed guiding panel (2, 2', 2'') to the upper surface (17) of the ski (1) in the central part (16) of the latter. The specified panel (2, 2', 2'') includes ribs (21, 22, 23, 24) which are inserted and attached to the grooves (101, 102, 103, 104) provided in the area of the upper surface (17) of the ski (1), while inside the specified ribs (21, 22, 23, 24) there are guiding grooves (210, 220, 230, 240) available for receiving and guiding of the legs (311, 312) of the guiding tongues (31, 32) and slip pieces (31', 32') of the ski binding.

Description

Ski or similar skating gear with built-in guides for guiding and positioning parts of the ski link

The invention relates to the field of skis, and relates to design and technological measures in the design and manufacture of skis, which allow the attachment of a ski link to the surface of the ski.

The invention is based on the problem of how, in a ski without significantly affecting the mechanical properties of the ski as such, either already in the manufacturing stage or also afterwards, the possibility of installing an assembly for positioning the parts of the ski link in such a way that forces from the bond area as far as possible directly transmitted to the area under the neutral bending axis of the ski, especially in the immediate vicinity of the curbs along the sliding surface of the ski.

In the context of the subject matter, the term ski refers to the preparation for skating in the snow or even at the water surface, in particular the ski, and generally also a snow or similar board, which serves a similar purpose as a ski. This kind of skating device is designed as a relatively flexible line, bending and torsion-bearing bracket and on the opposite side of the scope a sliding surface is received, which is optionally completed with curbs along the longitudinal edges. A curved tip is provided at one end of this line preparation from the substrate, and a curved tail at the opposite end, optionally from the substrate as well. Preferably, between the said tip and the tail, the device is arranged in the direction away from the base, and in the said area there is a central area in which the upper, i.e. a ski or similar attachment attached to a ski or similar skating device, side-by-side, facing the ski surface or a similar skating device to connect the ski equipment to a ski boot or similar footwear or shoes. with the user's foot.

From SI 200400052 oz. SI 200400310 or also e.g. from AT 502 887 A2 is a known ski with a built-in assembly for positioning and fixing the ski link in each position selected. In this case, a relatively large additional plate with longitudinal guides and arresting elements is attached to the upper surface of the ski beneath each of the ski link members, which are adapted to cooperate with the arresting elements with said panel of the participating further plate, to which the respective ski link portion is attached; which is guided in a first-rate panel. The presence of said plates on the upper surface of the ski results in the mechanical properties of the ski being altered at least to some extent, which is undesirable. This means that the flexural elasticity of the ski changes to some extent after the installation of the first plate. On the other hand, during the use of the ski, all of the two parts of the ski link are transferred first to the upper surface of the ski and then to the curbs, which in certain situations may result in an unfavorable distribution of forces or deformation of certain areas of the ski instead of maximizing the forces in the ski. custom transferred to the active area of each current curb.

In addition, EP 1 161 972 BI describes a skating device, in particular a ski, in which the rails which are mounted, in particular, are glued to the corresponding grooves, which were previously made into the upper surface of the ski, in order to attach parts of the ties to the upper surface of the ski. . Considering the needs regarding the possibility of moving both parts of the ski link in the longitudinal direction of the ski and thus adjusting the length of the respective ski boots, it is obvious that this is a considerable length of the mentioned rails. The rails are preferably trapezoidal in profile, and are adapted to cooperate with the sliding guides on each plate to secure the respective portion of the ski link. The rails must be relatively rigid in order to provide sufficient load capacity. On the other hand, the rails are arranged on the outer surface of the ski, and therefore at a considerable distance from the neutral bending axis of the ski. It follows from the foregoing that the presence of rails undoubtedly significantly affects the stiffness and / or stiffness. the flexibility of the ski, which differs significantly from the bending stiffness of the ski after the installation of the rails.

Furthermore, EP O 383 104 BI proposes a ski in which sliding mounting plates are provided on the upper surface, one of which belongs to the front or front. finger, the rest of the last or. the fifth part of the ski link so that said two parts of the ski attach each to its mounting plate. Each of said mounting plates is guided in the longitudinal direction of the ski along the upper surface of the ski, thanks to intermittent and crosswise ski guides spaced apart, each belonging to a sliding plate, substantially designed as profile C, the arms of which are inserted into the longitudinal grooves, each arranged in its lateral surface of the ski between the sliding surface and the upper surface. In any case, this is a design and technologically demanding solution, in addition to unwanted grooves in the lateral surfaces of the ski, the upper surface is provided with relatively rigid guide pins, which are again arranged at a considerable distance from the bending neutral axis of the ski and therefore, they undoubtedly significantly influence the flexural rigidity of the ski.

Further, EP 1 785 171 A2 proposes a ski comprising at least one anchor element for anchoring a portion of the ligament to the ski by means of an anchor insertable into said anchor element. The anchor element is designed as a guide of said anchor and is mounted below the ski surface i.e. in the core area. sails. Such an approach, which is relatively well known to those skilled in the art in the field of snowboard mounting (eg from WO 2004/078285 or also from Slovenian patent application P-200300015 published under No. 21410 A), in principle, results in relatively favorable anchoring of part of the ties closer to the neutral axis, which, in addition to reducing the impact on the rigidity of the ski, results in a more favorable transfer of forces to the active edge at each time. On the other hand, it must be borne in mind that at least two anchoring elements are required to secure each of the two parts of the bond, which must be inserted into the tool at a very precise distance from each other during the skiing process, e.g. flooded with materials that make up the ski. Thus, each ski requires the installation of at least four very precisely positioned anchor elements, which is associated with a high complexity in terms of technology. In the case of different ski constructions, different reinforcement layers may be provided, e.g. layer of laminate undisturbed below the upper surface of the ski at a distance from the neutral axis, all these parts need to be adjusted to such an extent that the anchor elements can cross the areas in which these supporting parts are arranged. It goes without saying that the installation of anchoring elements requires a fundamental change in the technological process of making skis, and that the simple retrofitting of anchoring elements, as provided for in EP 1 785 171 A2, into existing skis or also to skis made according to conventional manufacturing processes are by no means possible.

The invention relates to a ski or similar skating device with built-in guides for guiding and positioning parts of the ski link, wherein such ski is designed as a flexible line carrier with a neutral bending axis and a sliding surface is applied to the base facing the longitudinal edges. optionally completed with curbs. In addition, a curved tip is provided at one end of the ski from the base, a ski tail is provided at the opposite end, and between these ends there is a central area in which there is an upper, i.e. a ski or similar link attached to the ski facing surface or similar skating device from the surface facing the ski or similar skating device with a ski boot or similar footwear and, indirectly, with the user's foot. Said connection between the ski and the connection is provided by means of guide straps and associated sliders, inserted and guided in the corresponding guide grooves extending in the longitudinal direction of the ski.

According to the invention, a guide plate is mounted on the upper surface of the ski, which is provided with at least two longitudinally spaced pairs in the transverse direction of the ski facing the upper surface of the ski, and in each of said ribs there are There is also a groove open in the longitudinal direction of the ski and a groove open in the direction of the ski surface, which is adapted to receive, at each time, one arm of the respective guide strap and slider of the ski link. The connection between said plate and the ski is due to the insertion and fixing of said ribs into the corresponding grooves on the upper surface of the ski.

In a preferred embodiment of the invention, the guide plate is uniformly designed and comprises two pairs of ribs with guide grooves, of which one pair of ribs is located closer to the front end of the ski and the remaining two ribs closer to the rear end of the ski. An embodiment is also possible in which the guide plate is formed by two separate and longitudinally spaced ski regions, each comprising at least two spaced ribs with guide grooves in the transverse direction.

Furthermore, an extension is provided in the area of each of the guide grooves to allow insertion or insertion. removal by the groove of the participating arm of the guide strap or ski link slider. It is further preferred according to the invention that the bottom of each groove for receiving the rib of the guide plate is located below the neutral bending axis, namely in the area between the latter and between the sliding surface of the ski. It is further preferred that the bottom of each slot for receiving the guide plate rib is located adjacent to the available ski edge.

In addition, according to the invention, it is provided that the groove in the respective rib on the inner side facing the ski facing side is closed with a pad inserted at the bottom of the corresponding groove in the ski. Said guide plate is preferably attached to the upper surface of the ski in such a way that the available ribs of the plate are each inserted and glued in the corresponding grooves on the upper surface of the ski. Preferably, the rib in each of the adjacent grooves is glued preferably in the region of its facing outer lateral surfaces, at least one lateral surface of each rib may also be uneven.

The ski according to the invention may comprise at least one additional groove at its upper surface, in addition to the grooves for receiving the guide plate ribs, which extends at least approximately in the longitudinal direction of the ski and is adapted to increase the contact adhesive surfaces with the guide plate in the area below the upper surface of the ski. In this case, at least one additional groove is arranged between each pair in the transverse direction of the spaced grooves to receive the guide plate ribs, or between each pair in the longitudinal direction of the spaced grooves to receive the ribs of the guide plate, and optionally at least one additional groove may also represent an extension of at least one from the grooves to receive the guide plate ribs.

Furthermore, the grooves of at least one pair in the transverse direction of the ski of the spaced ribs of the guide plate are at least adapted to receive either symmetrically or asymmetrically designed arms of the guide strap and the associated ski link slider. In one of the possible embodiments of the invention, each of the leading link arms and the associated ski link slider is designed as a downward rotated letter T.

Between the ends 14, 15, respectively. between the tip and the tail, the ski 1 is preferably aligned in a direction away from the base, and in said region there is a central region 16 in which the upper, i.e. a ski or similar link attached to the ski facing surface 17 or to a similar skating device from the base facing the surface 17 to connect the ski or similar skating device to a ski boot or similar footwear or shoes available. with the user's foot.

In order to attach the ties to the ski 1, the latter is provided with guide rails 31, 32. Thus, e.g. in FIG. 1 illustrates a leading strap 31 of the front of the bond and a guide strap 32 of the rear of the bond, e.g. present throughout the ski 1. During mounting of the link, a slider 3Γ is mounted along the guide spindle 31, and a slider 32 'along the guide spindle 32 of the rear link, whereby, for the purposes of understanding the invention, each of said sliders 3', 32 'can essentially be presents skiing or skiing. the front or back of it.

According to the invention, at least one guide plate 2, 2 ', 2 is provided on the upper surface 17 of the ski 1, which is fixed to the ski 1 on the one hand and, on the other hand, is adapted for guiding said guide straps 31, 32 and sliders 31', 32 'ski links in the longitudinal direction of ski 1, namely in the direction from the central region 16 of ski 1 to each of the two ends 14, 15 of ski 1.

Said guide plate 2, 2 ', 2 can be designed as either a single plate 2 (Figs. 2 and 3), adapted to guide the two guide joints 31, 32 of the front and rear of the ski link together with the respective slider 3 deli, 32 ', or also as a two-part formation, namely parts 2', 2 consisting of a formation on the upper surface 17 of ski 1 (Fig. 1), in which case each of said parts 2 ', 2 is adapted to cooperate with one guide strap 31, 32 which, together with the respective slider 3Γ, 32 ', is in each case one of the parts of the ski link.

The guide plate 2, 2 ', 2 is basically designed as a relatively flexible plate whose presence on the upper surface 17 of the ski has virtually no significant effect on the flexibility and / or flexibility. deformability of the ski itself 1. In addition, the board 2, 2 ', 2 may consist of an expensive plastic material, its thickness or thickness. however, the height above the upper surface 17 of ski 1 may be relatively small, e.g. only 2-5 mm, it is possible to optionally reach this height eg. to increase standing height also increase. Particularly in the case of a thick plate 2, 2 ', 2, a two-piece plate 2, 2', 2 may be preferred.

The ski 1 according to the invention on the upper surface 17 comprises an anchor formation 10 (Fig. 8) formed by at least two doubles in the longitudinal direction of the ski 1 of the running grooves 101, 102; 103, 104, the grooves being 101, 102; 103, 104 of each pair are parallel and spaced in the transverse direction of ski 1, and at the same time two grooves 101, 102 are mentioned; 103, 104 are spaced apart from one another in the longitudinal direction of ski 1 such that one pair of grooves 101, 102 is located closer to the front end 14 of ski 1 and the remaining two grooves 103, 104 are closer to the rear end 15 of ski 1.

Further, according to the invention, either the uniquely designed guide plate 2 or also of two separate parts 2 ', 2 the standing plate 2 on its side facing 20 (Fig. 5) comprises the aforementioned grooves 101, 102; 103; 104 ribs 21, 22, 23, 24 or similar projections arranged on the upper surface 17 of the ski 1, which can be tightly fitted into said grooves 101, 102; 103, 104 on the upper surface 17 of the ski 1, wherein in each of said ribs 21, 22, 23, 24 is provided in a profile properly shaped and open a guide groove 210, 220, 230 in the direction away from the upper surface 17 of the ski 1, 240, which is adapted to cooperate with each associated limb 311, 312 of each associated guide strap 31, 32 and at the same time with the respective ski link 3Γ, 32 '. Each of said guide grooves 210, 220, 230, 240 comprises a corresponding extension 210 ', 220', 230 ', 240' (Fig. 7), in the area of which the available limb 311, 312 in the respective groove 210 may be inserted, 220, 230,240 oz. its removal from the latter.

The unobstructed sliding of the arms 311, 312 of the guide straps 31, 32 and the sliders 3Γ, 32 'in said guide grooves 210, 220, 230, 240 is preferably ensured by the presence of the corresponding liners 211, 221, which close said guide grooves 210,220, 230, 240. This type of panel design 2, 2 ', 2 may be preferred for several reasons. On the one hand, the construction of the plate 2, 2 ', 2 in such an embodiment is relatively simple. On the other hand, the substrate 211, 221, 231, 241 may each consist of a material with good sliding properties and high abrasion resistance. Furthermore, the presence of this type of support in the groove 210,220, 230,240 effectively protects the ski core 1 from external influences.

Proper mounting of panel 2 or. of parts 2 ', 2 of panel 2 to the upper surface 17 of ski 1, after insertion of ribs 21, 22, 23, 24 into grooves 101, 102, 103, 104 is made by gluing, with relatively large lateral surfaces 212, 213; 222, 223 of each rib 21, 22, 23, 24 provide a good basis for establishing a reliable connection between ski 1 and plate 2, 2 ', 2'. The adhesive surface can be further enlarged if, e.g. lateral surfaces 212, 213; 222, 223 of each rib 21, 22, 23, 24 are embossed (Fig. 15). A further measure which is possible in the direction of increasing the adhesive surfaces between the ski 1 and the plate 2,2 ', 2 is e.g. that, in addition to the guide grooves 101, 102, 103, 104, at least one additional longitudinal groove 105, 105 ', 105 is provided on the upper surface 17 of the ski 1, with which it can then participate in the sketch not shown pen, which may be in addition to this The existing ribs 21, 22, 23, 24 are provided on the ski surface 1 facing surface 20 of the guide plate 2 ', 2', 2 (Figs. 9 and 10). Each such additional groove 105, 105 ', 105 may be provided either in the area between guide grooves 101, 102, 104, 104 (Fig. 10) or in each case longitudinally connecting adjacent guiding grooves 101, 103 or. 102, 104, and may optionally also be an extension of at least one of the leading grooves 101,102, 103, 104 (Fig. 9).

As can be seen in particular in FIG. 11 to 17, the depth of said grooves is 101,102, 103, 104, 105 and, accordingly, the height or height. the depth of the ribs 21, 22, 23, 24, such that the bottom of the respective groove 101, 102, 103, 104 is below the neutral bending axis O of the ski 1. This means that the loads from the arms 311, 312 of the respective guide strap 31, 32 the ski ties 1 are transferred to the ski 1 in the area below the neutral axis O and in the vicinity of the active curb 12.13 at each time along the sliding surface 11 of the ski 1.

Further, on the upper surface 17 of the ski 1, in addition to the aforementioned grooves 101, 102, 103, 104, there may be provided appropriately arranged blind holes 106, 107, 108, 109 (Fig. 8), adapted for receiving tight-fit studs 251,252,253, 254 available on the ski surface 1 facing surface 20 of the guide plate 2, 2 ', 2, thereby achieving even more precise and reliable positioning of the guide plate 2, 2', 2 on the upper surface 17 of the ski 1, while even more effective attachment of the respective guide plate 2, 2 ', 2 to the upper surface 17 of the ski 1.

It will be appreciated by those skilled in the art that the respective guide arms are 311, 312; 321, 322 guide straps 31, 32, and 3T sliders, 32 'ski ties may differently provide different guide grooves 210, 220, 230, 234 and associated extensions 210', 220 ', 230', 234 '. Thus, in the embodiment of FIG. 11 - 15 grooves 210, 220, 230, 234 asymmetrically designed and adapted to guide arms 311, 312, which are L-shaped and face each other. In the embodiment of FIG. 16 are again asymmetrically designed grooves 210, 220, 230, 234 adapted to guide arms 311, 312, which are L-shaped and facing each other, while in the embodiment of FIG. 17, the grooves 210,220, 230, 234 mentioned are symmetrically designed and adapted to guide arms 311, 312, which are designed in a downward shape against the sliding surface 11 of the inverted letter T.

This completely solves the aforementioned problem. For ski 1, without significantly affecting the mechanical properties of the ski 1 as such, either in the construction phase or afterwards, it is possible to implement the mounting of the arms 311,312 of the guide straps 31, 32 and the sliders 31 ', 32', and thus of the assembly for positioning the parts of the ski link. in such a way that forces from the bond area are transmitted to the area under the neutral bending axis 0 of the ski 1, especially in the immediate vicinity of the curbs 12,13 along the sliding surface 11 of the ski 1.
