Technical Field

This technical solution relates to a sports equipment, particularly for ride on snow or artificial surface.

Background Art

This technical solution follows the previous technical solution named "Sports equipment for ride on snow", registered as utility model CZ19782 dated 29.06.2009, which is characterized by that it comprises two boards for simultaneous use, the boards having lateral cut and are at least on one side flexed upwards, each board containing binding for shoe and the longitudinal axis of the board being horizontally asymmetrical to the longitudinal axis of the binding. The issue of the former solution lies in the fact that the ride is physically demanding, particularly in heavy terrain. Therefore, it is impossible to make use of such board safe for kids and untrained persons.

Disclosure of the Technical Solution

New technical solution avoids the disadvantages of the previous technical solution by allowing a significantly better control over the handling two boards, wherein each is attached to one leg of the rider, characterized in that the two boards are interconnected permanently or temporarily via a coupling mechanism BO that the two boards in their longitudinal axis are parallel to one another. The coupling mechanism may be formed with the aid of technical features, which will be described below. Providing two boards for driving with coupling mechanism is the core idea of this technical solution, which will be developed further in specific embodiments. The coupling mechanism described below can also be used for connecting boards of two and more riders by interconnecting them with this coupling mechanism, i.e., at least one pair of boards of one rider connected by coupling mechanism is coupled via a coupling mechanism with at least one pair of boards of another rider whose boards are connected by the coupling mechanism.

In one embodiment of the present Invention according to Fig. 1 to 3, a connecting mechanism comprises at least two swinging arms, two holders for mounting the arms to the board, the holder with the arm and the arms are connected to each other with a pivot allowing rotation of the arms at both ends thereof about the longitudinal axis of the board. Arm holders are arranged in such a manner that one holder on one board is placed in front of the binding and on the second board the holder is placed behind the binding, i.e. so that the coupling mechanism is always located between the bindings. Preferably, the coupling mechanism further comprises at least one stopper on the holder placed under or behind the fastening of the arm with a pivot, the stopper shall prevent the arm from touching the board or the holder and thereby prevent damage to sports equipment. In another preferred embodiment, one of the arms is extended in the longitudinal axis of the board so that there is sufficient distance between the two bindings to ensure the stability of the rider. In another preferred embodiment, the arm length in the longitudinal axis of the board is adjustable, e.g. in that the arm is telescopic. In another preferred embodiment it is possible to adjust the rotational stiffness of the arm and, eventually, one arm or both arms can be fixed so as not to move against each other. In another preferred embodiment the length of at least one of the arms in the transverse axis of the board can be changed, e.g. again in that the arm is telescopic, thereby allowing to additionally change the mutual distance of the two boards. Disconnection may for example be ensured by that the coupling mechanism comprises a quick coupling, for example at a contact point of the two arms by releasing the pivot from one of the arms, or the quick coupling component forms part of any of the arms, wherein the disconnection can be achieved by releasing the lever connection. In a preferred embodiment, it is possible to uncouple the coupling mechanism during the ride.

In another embodiment shown on FIO. 4 to 6, the coupling mechanism is formed by using two pads for receiving the arm holders, wherein each of the pads is attached to one board. The arm holder is mounted to each of the pads by means of fixed or rotatable joint, wherein in case of need, it is thereby possible to regulate the rotation position of the arm holder in the longitudinal axis of the boards. The arm holder is connected with the arm rotary joint on one side so that the arm can be lifted or tilted in the longitudinal axis of the boards up to the vertical position, i.e. perpendicular to the board. For this purpose, a rotary joint is provided with a spring which is supported on the second end by a stopper formed on the arm. The spring thereby pushes the arm to the vertical position. At the end of the arm a retaining member provided with a head is connected with a rotary joint, wherein the head for connection of the two boards by coupling mechanism is received with the shape- complementary cavity formed in the second arm of the coupling mechanism. In Figs. 4 to 6, the cavity is formed so that the head of the retaining member could not be released spontaneously, i.e. in the longitudinal direction is continuous so that the head of the retaining member can move inside, wherein the head of the retaining member has a greater width than the remaining portion of the retaining member and, therefore, the end of the cavity of the arm closer to the second arm is narrowed at its upper edge so that it accommodates the head, but does not allow releasing of the head of the retaining member when the head is retracted to its outermost position closer to the second arm. Preferably, the arm having a cavity contains a safeguard against accidental release of the retaining member from the cavity. The rotary joint connecting the arm with the retaining member is also provided with a spring which draws the retaining member to the arm so that the head of the retaining member touches the arm. For this purpose, the retaining member is also provided with a spring stopper of the rotary joint. The arm provided with a cavity is mounted to the arm holder with a joint, preferably with two screw joints. Said arm holder is connected to the holder pad which fixes the holder to the board. Preferably, the center of the coupling mechanism passes through the longitudinal axis of both boards.

In a further exemplary embodiment according to Fig. 7 to 8, the coupling mechanism is formed in a structurally simpler way, so that it comprises holders mounted on each of the boards, wherein a head of coupling mechanism is inserted to each of the holders, and these two heads are firmly connected with a body. The body of the coupling mechanism is rigid or flexible. The material of the coupling body can be a strong steel wire rope with appropriate flexibility. At least one head of coupling mechanism, or preferably both, can be disconnected from the respective holder. Head of the coupling mechanism can be released when the user unlocks it. The fixation of the head into holder can be assured with an appropriate locking element or ratchet. In this variation, the rider can arbitrarily set the mutual position of the boards during driving by sliding his foot or feet, respectively.

In accordance with the above description, the coupling mechanism according to any of the preceding embodiment can be disconnect to ensure free movement of both legs during the ride, or during the movement on a plane or uphill, respectively. With a possibility of flexible connection of the boards, this new solution allows to set the level of mutual active suspension.
