    专利说明:

    The invention relates to a roller ski for training Skatingschritts, with an elongated spar member which is connected at the front end with a front wheel receiving element for at least a front wheel and at the rear end with a rear wheel receiving element for at least one rear wheel, wherein the front Radaufnahmeelement and the rear Radaufnahmeelement are each angled upwards from the longitudinal plane of the Holmelements.
    Such roller skis have long been in use to allow ambitious cross-country skiers to practice the skating or diagonal pace during the summer months. Usually, these roller skis have an elongated spar, which has at the ends depending on a wheel receptacle for the front or rear wheel. In the prior art, however, ski rollers have already been proposed in which the wheel receivers are bent upwards, so that the spar is arranged below the wheel axles. Thus, the center of gravity of the skiroller can be arranged closer to the ground, whereby the skating step of cross-country skiing can be trained closer to reality. An example of such a roller ski is shown in WO 02/09828 A1.
    In the known embodiments, however, the lowering of the center of gravity by the bent wheel receivers is only to a limited extent feasible, otherwise the side edges of the spar could come into contact with the ground. However, this would disadvantageously bring about a wear or damage to the skiroller. On the other hand, although a flatter geometry of the wheel bearings would allow the practice of skating technique without contact with the ground, but the benefits of center of gravity reduction would be limited use.
    In WO 2010/034695 Al another roller skis described in which the wheel axles, however, are arranged substantially in the longitudinal plane of the spar. At the bottom of the spar a longitudinally extending stiffening element is provided. This ski roller disadvantageously has a comparatively high center of gravity, which is used for training the skating
    Step is not optimally suitable.
    Furthermore, DE 10 2007 027 002 B4 discloses a roller ski in which the upper side of the spar is arranged substantially in the same plane as the upper side of the wheel receiving element. In this construction, the footprint for the foot of the user, however, is located at a greater distance to the ground, whereby the skating movement in cross-country sports can only be simulated insufficient. The known roller skis has stability reasons in the central region of a T-shaped cross section and at the end regions of a rectangular cross section.
    Accordingly, the object of the present invention is to eliminate or mitigate the disadvantages of the prior art. The invention is therefore particularly aimed at creating a roller ski of the type mentioned, which is equipped with a low center of gravity, but without affecting the exercise of the skating step.
    This object is achieved with a roller ski according to claim 1. Preferred embodiments are given in the dependent claims.
    According to the invention, the spar element has at least one lateral recess on the underside, with which the spar element can be arranged in a position tilted about its longitudinal axis without contact to a flat surface when the skating step is exerted.
    Accordingly, the spar element in the region of the lateral recess has a small wall thickness (defined as extension perpendicular to the longitudinal plane of the Holmelements) than in a central cross-sectional region of the Holmelements. The Radaufnahmeelemente are angled relative to the longitudinal plane of the Holmelements upwards, so that the upper side of the Holmelements is arranged below a the wheel axles of the front wheel and the rear wheel having plane. On the one hand, this embodiment has the advantage that, regardless of its low center of gravity, the spar element can be reliably held at a distance from the level ground when the spar element is exercising during training
    Skating step temporarily tilted out of the horizontal middle position. On the other hand, the stability of the Holmelements is less affected by the lateral recess than in prior art designs in which the exemption of Skatingbewegung was trying to reduce the wall thickness of the Holmelements across the width evenly. Thus, a roller skier with lowered center of gravity is created with which the skating step for cross-country skiing can be trained more realistic than in the prior art. By the lateral recess wear or damage to the Holmelements can be reliably avoided by a sliding contact with the ground, creating a particularly durable exercise equipment is provided.
    In order to release the tilting movement of the skirl roller when the skating step is exercised, it is in principle sufficient if a lateral cutout is provided on the lower inner edge of the skip element. In order to provide an identical pair of roller skis available and thus to avoid different configurations for the left and right foot, however, it is preferably provided that a respective lateral recess is provided at the lower longitudinal edges of the Holmelements, wherein the two lateral recesses preferably in Essentially ident are formed.
    According to a particularly preferred embodiment, the lateral recess extends at least along a central longitudinal section of the Holmelements. Due to the burden of the weight of the user, the spar member is bent more in the central region between the Radaufnahmeelementen, with a grinding of the Holmelements is reliably avoided on the ground by means of the lateral recess in this area.
    To equip the roller ski with a low center of gravity, it is also advantageous if the lateral recess extends from the central longitudinal section in a front and / or in a rear longitudinal portion of the Holmelements. Preferably, the lateral recess is formed symmetrically with respect to a median plane of the Holmelements perpendicular to its longitudinal extent. The lateral execution extends before preferably without interruption from the central longitudinal section in the front and in the rear longitudinal portion of the Holmelements.
    In order to arrange the spar member in the tilted position during skating step at a distance to a flat surface, it is advantageous if the lateral recess in cross-section is substantially triangular. The triangular design of the lateral recess here refers to a rectangular basic shape of the cross section of the Holmelements. Preferably, the cross member in cross section in the shape of an isosceles trapezoid. In this embodiment, the spar member in the region of the lateral recess on a flat boundary surface, which is arranged with respect to the untilted normal position of the Holmelements at an angle to the horizontal (or to the flat top of the Holmelements). This inclination angle of the flat boundary surface of the lateral recess is preferably between 20 ° and 60 °, in particular between 30 ° and 50 °.
    According to an alternative preferred embodiment, the lateral recess in cross-section is substantially circular sector-shaped. Accordingly, the spar member in this embodiment in cross-section on a circular arc-shaped boundary line on the lateral recess, so that the lateral recess is concave at the lower longitudinal edge of the Holmelements. This embodiment has the advantage that, in the tilted position, the spar element can be protected against contact with smaller objects on the level ground, such as pebbles, when the skating step is being performed.
    In order to take into account the weakening of the deflection of the Holmelements towards the Radaufnahmeelementen, it is advantageous if the width and / or height of the lateral recess decreases starting from the central longitudinal portion to the front and / or to the rear longitudinal portion of the Holmelements out. Thereby, the lateral recess can be precisely adapted to the deflection of the Holmelements, which decreases from the central longitudinal section to the Radaufnahmeelementen out. Advantageously, on the one hand, the skating motion is released in this way, on the other hand, the stability of the
    Holmelements is affected as little as possible by the lateral recess.
    In order to design the roller skis on the underside with the lateral recess, it is advantageous if the spar member on the underside of a plastic element, in particular of a thermoplastic material, preferably of polyurethane, polyamide or acrylonitrile-butadiene-styrene copolymer, on which the at least one lateral recess is formed. The plastic element preferably extends over the entire width of the Skiroller.
    To achieve a weight-saving on the one hand and on the other hand tensile structure, it is advantageous if the spar member has a honeycomb core, in particular of a composite of wood and cardboard, which is at least partially covered with one or more layers of fiber-reinforced plastic. At least one layer of fiber-reinforced plastic, in particular of glass-fiber-reinforced plastic, is preferably provided on the upper side of the honeycomb core. Furthermore, a layer of carbon fiber reinforced plastic is preferably provided on the outside of the Holmelements, which extends at least over the top and the two longitudinal sides of the Holmelements.
    If the plastic element is exposed at least in the region of the lateral recess on the outside of the Holmelements, the plastic element can also provide for the protection of the lower longitudinal edge of Skiroller in the lateral recess. When skating is practiced, the lower longitudinal edges of the skiroller are particularly susceptible to damage from obstacles on the road. The plastic element can withstand even stronger impacts in the region of the lateral recess, so that damage to the Holmelements is avoided. For this purpose, the plastic element is preferably made of a thermoplastic material such as polyurethane, polyamide or acrylonitrile-butadiene-styrene copolymer, since these materials are characterized by a high impact strength. As a result, the service life of the skirl roller can be extended compared with designs in which sensitive layers, such as carbon layers, are provided in the region of the lower longitudinal edges on the outside.
    To absorb tensile forces, it is favorable if the underside of the plastic element between the lateral recesses is covered by at least one layer of fiber-reinforced plastic. Accordingly, the boundary surfaces of the lateral recesses are formed by sections of the plastic element, whereby an efficient edge protection is achieved. In contrast, the underside of the Holmelements between the lateral recesses is formed by the at least one layer of fiber reinforced plastic, whereby the transmission of tensile forces can be improved. It is particularly preferred if the spar member has an outer layer of carbon fiber reinforced plastic, which is interrupted in the region of the lateral recesses, so that the plastic element is arranged exposed in this area.
    As known per se in the prior art, the spar element can have a holding device for a cross-country binding at the top. The cross-country binding may be formed according to the prior art, so that it is not discussed in detail.
    The invention will be explained below with reference to preferred embodiments, to which it should not be limited, however. In the drawing shows:

The roller skier 1 has an elongated body element or spar element 2, which is arranged substantially horizontally in the unloaded and untilted normal position. The spar member 2 is connected at the front end with a front wheel receiving element 3, on which a front wheel 4 is rotatably mounted. Furthermore, the spar member 2 is connected at the rear end with a rear wheel receiving element 5, on which a rear wheel 6 is rotatably mounted. The front wheel receiving element 3 and the rear wheel receiving element 5 are each angled obliquely upward from the longitudinal or main plane of the Holmelements 2, so that the upper side of the Holmelements 2 below the axis of rotation 4 'of the front wheel 4 and the axis of rotation 6' of the rear wheel 6 extending level extends. In Fig. 1 also front and rear splash guard elements 7 can be seen, which are fixed to the front wheel receiving element 3 and the rear wheel receiving element 5. In addition, at the top of the Holmelements 2 a (schematically shown) holding means 8 for a conventional cross-country binding (not shown) is provided. For the purposes of this disclosure, the statements "front", "rear", "top" and "below" refer to the position of use of Skiroller 1 when rolling on the ground 9.
    1, the bar element 2 has at least one lateral recess or recess 10 on the underside facing a flat base 9 (cf., FIG. 2) such that the bar element 2 is in a position tilted about its longitudinal axis 11 is arranged without contact to the substrate 9 when the skating step is performed. The recess 10 is thus adapted to release the tilting movement of the handle member 2 which is required for practicing the skating technique (i.e., a movement corresponding in basic form to the skating step).
    As shown in FIG. 3, in the embodiment shown, two lateral recesses 10, namely one lateral recess 10 each at the two lower longitudinal edges or edges of the Holmelements 2, are provided. The two lateral recesses 10 are formed ident, so that the same roller scooter 1 can be used for both feet.
    2, the lateral recesses 10 extend without interruption along a central longitudinal section 12 of the Holmelements 2. In addition, the lateral recesses 10 extend from the central longitudinal section 12 without interruption forward in a front longitudinal section 13 and uninterrupted back into a Rear longitudinal section 14 of the Holmelements 2. With the longitudinal sections 12, 13, 14 consecutive sections of the Holmelements 2 are referred to in the longitudinal direction 11 of the Skiroller 1.
    In Fig. 3, the cross section of the skiroller 1 in the central longitudinal section 12 can be seen. In the embodiment shown, the two lateral recesses 10, based on an imaginary rectangular basic shape of the Holmelements 2, triangular in cross section, whereby the spar member 2 assumes the shape of an isosceles trapezoid in cross section.
    As is further apparent from FIG. 3, the spar element 2 has a one-part plastic element 15 on the underside, which extends over the entire width of the hollow element 2. The plastic element 15 has lateral boundary surfaces 16, which limit the lateral recesses 10 of the Holmelements 2. 3, planar boundary surfaces 16 are provided, which are arranged at an acute angle to the horizontal underside of the Holmelements. The plastic element 15 is formed from a thermoplastic material, for example thermoplastic polyurethane, polyamide or acrylonitrile-butadiene-styrene copolymer. These materials are characterized by a high impact resistance. In order to protect the lower longitudinal edges of the Holmelements 2 in use, the boundary surfaces 16 of the plastic element 15 are exposed in the region of the lateral recesses 10 on the outside of the Holmelements.
    3, the spar member 2 has a honeycomb core structure 17, hereafter honeycomb, of a combination of wood and cardboard, which honeycomb core 17 is laterally bordered by side tongues 18 made of wood. At the top of the honeycomb core 17 at least one (schematically drawn) layer 20 of (glass) fiber-reinforced plastic is provided. Accordingly, a further layer 20 'of (glass) fiber-reinforced plastic is provided on the underside of the plastic element 15. This structure is encased with a layer 21 of carbon fiber reinforced plastic, which layer 21 is interrupted in the region of the boundary surfaces 16 of the plastic element 15. The individual layers of Skirollers 1 are glued together in a known manner.
    FIGS. 4 to 10 show further embodiments of the skirl roller 1, which differ in the design of the lateral cutouts 10.
    According to Fig. 4, 5, the spar member 2 is formed according to the embodiment of Figs. 1 to 3 with a trapezoidal cross section, wherein in Fig. 5 only schematically the outer contour of the cross section, without inner structure is visible. In this embodiment, on the one hand, the width of the lateral recess 10, i. their extent in the longitudinal plane of the Holmelements 2, and on the other hand, the height of the lateral recess 10, i. their extension perpendicular to the longitudinal plane of the Holmelements 2, from the central longitudinal section 12 forward to the front longitudinal section 13 and from the central longitudinal section 12 to the rear to the rear longitudinal section 14 of the Holmelements 2 from. As a result, the lateral recesses 10 extend from the central longitudinal section 12 forward and backward gradier-Lich. The front wheel receiving element 3 and the rear wheel receiving element 5 are rectangular in cross section.
    According to Fig. 6, 7, the lateral recesses in cross-section (relative to a rectangular basic shape) are formed substantially circular sector-shaped. Accordingly, the lateral boundary surfaces 16 of the lateral recesses 10 are curved in this embodiment in a circular arc inwardly. The circular sector-shaped recesses 10 extend in the embodiment shown in the central longitudinal section 12 substantially over the entire height and each over approximately half the width of the Holmelements second
    According to Fig. 8, 9 also circular sector-shaped recesses 10 are provided, which, however, have a smaller width and a lower height than in the embodiment of FIGS. 6, 7. In contrast to the other embodiments, the width of the lateral recesses according to FIG. 8, 9 in the longitudinal direction along the central longitudinal section 12 to the front longitudinal section 13 and in the rear longitudinal section 14 is substantially constant, wherein the lateral recess adjacent the front Radaufnahmeelements 13th or the rear wheel receiving element 14 over a short section expires.
    According to Fig. 10, 11, the lateral recesses 10 are triangular as in the embodiment of Figs. 1 to 3, wherein the lateral recesses, however, in the central longitudinal portion 12 substantially over the entire height of the Holmelements 2 and each approximately over half the width of Holmelements 2 extend.
