Description

Device for a sliding movement on the snow, driven by the wind,

The invention relates to a wind-driven device for a sliding movement of the persons on the snow or ice, insbesondre provided with a sail device.

The previous products of the similar kind arise basically from two concepts.

The first concept usually applies a common sail for windsurfing and various constructions for a sliding movement on the snow or ice, some constructions of which arise as a construction of snowboard or monoski, others from the windsurfing float, with a Series of which are provided with the various longitudinal ribs, profiles, runners or knives for increasing the resistance to the lateral force. This subheading includes in particular "surfschütten" (snowboard) according to the document DE-OS 37 05 568, for gliding on a solid surface, especially on snow, ice or on the track of plastic, with a mast and board (a plate). The board has on its lower sliding surface a superior runner, which is flat in the direction of sliding and is provided in the rearward direction with a downwardly conducting sharp edge.

Furthermore, this includes an existing in two or three parallel skis device, which is provided with a platform for the driver's standing. This is, for example, "Dispositif de sport de glisse a voile" (A sportive gliding device with sail), according to the font FR 2 796 850, with a basis for the attachment of the Mast is formed, which is provided with a non-slip surface on which the user stands. The device is further provided with a lubricant in the form of two skis. This is attached to the base with the help of an inserted agent. The inserted means is provided with the flexible and damping plates and with the fasteners on the lubricant. The fastening means are provided with a means for rapid blocking and unblocking. Also included herein is an apparatus "winter sports equipment" according to document DE-OS-36 28 623 formed by a platform for standing and two runners connected to the platform by means of a swivel mechanism The platform is provided with the loops for fastening the feet Mistake.

In this arrangement, the driver is free on the device, in some cases he can use loops for the insertion of feet. Such a solution, well proven in windsurfing, allows the driver to change the position of the feet as needed depending on the course of the ride in view of the wind, but when driving on the snow, it does not secure the driver enough firm connection of the feet with the lubricant, and therefore it does not provide optimal control over the ride. Another concept consists in a conventional skis ausnützenden solution where the driver is in a familiar ski binding frontal. For example, a sailboard sail is used for propulsion, which is connected to the skis by means of the mechanism which allows a free movement of the skis within certain limits and at the same time delimits the position of the joint of the sail, or a certain wing that the driver holds in his hand, or a kitting kite, etc. In particular, this device includes a device according to the document WO9408670 "Ski sailing method and apparatus." The device is The device provides a joint limited independent both pivotal and vertical movement of each ski, approximately in a common movement of the skis, which in the rotation, plowing and the other common Skiing are required.

Although these solutions meet the requirement of a firm connection of shoes with the skis, but allow only a frontal position, which is not suitable for some courses. In particular, driving for the lateral and frontal courses is difficult, and in some cases even impracticable.

Furthermore, well-known snowboards are known, which are provided individually for each shoe with a binding on a pivoting and blocking platform, which is attached to the body of the snowboard. These solutions are described, for example, in the specifications CZ PV 1994-1813 "Binding for snowboard" or CZ PV 1996-1310 "Method and device for tilting and lifting the binding for snowboard". A disadvantage of these arrangements is that they are designed individually for each shoe. These mechanisms are components of the common snowboard bindings in the various forms and, in essence, they serve to fine-tune the position of the binding according to the individual needs of the particular driver. A disadvantage of these solutions is that they at least while driving the - A -

do not allow fundamental changes of position, in the sense of confusion of the front and rear foot - the left front, the right rear ("regular"), or the right front, the left rear ("goofy"), taking over the frontal position and all liners are not talking. Such changes are possible here only after the dismantling of the binding but for snowboard without sails quite sufficient. It is the object of the present invention to eliminate the disadvantages of said solutions, and at the same time to take advantage of the two concepts. Nevertheless, the author recommends to move on the snow a conceptually outgoing from the snowboard means, best in one of the modifications described below, if necessary to apply a common snowboard, it is possible, even another means, for example one from the above apply successfully. In addition, the term "lubricant" is used in the text, and the author recommends that you use a sailor's sails.It is also possible to use other products for a similar purpose, so here is a general term "sails".

The indicated disadvantages are inventively eliminated from the larger part and the specified object is specifically by means of a device for a sliding movement on the snow, which is driven by the wind, consisting of a sail, a particular formed by snowboard lubricant, and in particular by a binding formed for snowboard, which is connected to the lubricant with the possibility of rotation about the vertical axis, and provided with a mechanism of safety connection with the lubricant, the transverse profile of the runner of the ~~ Ö "**

Lubricant changes along its length, characterized in that the binding is arranged on a pivotable platform, with which it is firmly connected, and which with a possibility of controllable rotation about its vertical axis together with the binding, with a Possibility of braking its rotational movement is arranged ..

According to a further implementation, the pivotable platform consists of a base and a base rotatably mounted insert, wherein the base is fixedly connected to the lubricant, and on the base by means of the center screw, the insert is rotationally fixed about the vertical axis.

After a further implementation, a ball bearing is arranged between the base and the insert, which is formed by a row of the balls and a ball cage, wherein the ball cage is freely rotating about the center screw and is provided with openings for accommodating balls. After further implementation brake pads are attached to the insert, which also serve as seats for mounting the binding, and are provided with the brake segments, wherein the insert further tension springs are attached to the attraction of the brake shoes and the simultaneous pressing of the brake segments are arranged on the cylindrical wall of the base and for braking the pivotable insert in a required position.

After a further implementation, the brake shoes are fixed to the insert by means of fixing screws for minimizing their vertical movement, wherein in the horizontal plane, the brake shoes to the screws rotating around a Angle are arranged, wherein the angle is limited by the movement of the fixing screws in the arranged in the insert oval openings.

After further implementation, the insert is further provided with an adjusting screw for adjusting the bias of the tension springs.

After a further implementation, the pivotable platform from the braked position by means of the pressure of the driver against the force of the tension springs with the heels of each other and the tips to each other, for a separation of the brake shoes and the brake segments from the contact against the cylindrical wall detachable from the base.

After a further implementation, the pivotable platform is connected to the lubricant by means of the safety mechanism which includes the pressure springs connected to the pressing elements, which engage with their outer shape in the depressions formed on the inner sides of the strips, which fastened on the lubricant are, wherein an adjustment of the contact pressure of the pressure springs by means of the adjusting screw mounted on the base is changeable.

[0018] According to a further implementation, the cross section of the blade of the lubricant varies along their length, so that the functional portion of the runner which is in contact with the terrain, in ^• the front portion is convex, with the edges above the plane of the blade , and in the back part is concave, with a possibility of forming at least two longitudinal concave strips, at least one edge being below the plane of the runner. The main advantage of the solution is that it allows the driver to achieve an optimal orientation of the position for all possible courses and to make their changes at any time while driving, and at the same time it offers a firm connection with the lubricant, and thus giving the driver a high degree of control over the ride.

Another advantage of the solution is that the insert can be fastened with the binding to the different types of lubricant, for movement on the different types of surface, for example for lubricants, with the skates for movement on the ice , or even provided with the scooters or wheels for a solid surface.

The variant with the safety mechanism, which shuts off the platform of the lubricant when exceeding the set forces, can prevent injury, in particular in the example of the case.

An advantage of the variant with the modified snowboard is that the angle of the peripheral edge is smaller in the front part in view of the surface of the snow or ice, and on the contrary in the rear part, and a change of this angle can be continuous, so that with the small inclination of the lubricant, the center of gravity of the lateral resistance is pushed more backwards, so that as the lubricant advances forward, this center of gravity is continuously pushed forward to its usual position in the middle of the effective length of the edge. For the larger slopes, the edge cuts one off the snowboard or from the skis known classic carving (bow). Moreover, in the case of using the variant having a plurality of concave edges and an inner edge (inner edges), when the lubricant is laid flat, the inner edge (y) is emphasized, which further increases the lateral resistance in the rear part, and more it allows the driver to avoid unwanted activation of the leeward Kannte. The above-described design of the skid and the edges optimizes the position of the center of gravity of the lateral resistance, offers a high ride stability, good guidance in the direct direction and also in the arc, allows a sensitive steering of the lubricant by means of the inclination of the lubricant and also the manipulation with the sail, allows a carving, a controlled sliding, etc.

Thanks to the above-mentioned advantages, the invention makes it possible to drive at a high speed and also to carry out the radical maneuvers, jumps and a lot of freestyle tricks, under a wide range of conditions, types of surface and terrain.

In the following examples of the invention are explained in more detail with reference to figures. In the drawings:

The device according to the invention according to Fig. 1 consists of a sail 1 and a particular by

2. The lubricant 2 is provided with a rail 3 for the connection of the lubricant 2 with the

Sailings 1 provided. Furthermore, it contains one with a

Binding 6 snowboard platform 5 provided with snowboard.

The sail 1 is with the lubricant 2 in its front Part connected by means of a joint 4, which allows a free inclination and rotation of the sail 1, and by means of the rail 3, which allows an optimal adjustment of the position of the joint 4. For the lubricant 2 and the pivotable platform 5 is fixed, to which the binding 6 is screwed. The pivotable platform 5 is horizontally placed at a sufficient height above the lubricant 2, so as not to prevent the transverse inclination of the lubricant 2. In spite of the fact that the lubricant 2 is generally inclined during travel, the term "horizontal" refers to such a situation where the pivotable platform 5 is also arranged "horizontally ^" , ie in a position parallel to the lubricant 2 analogical situation also applies to the further specified terms, for example, "vertical axis", "vertical", etc.

The pivotable platform 5, as shown in Fig. 2 to 6, consists of a base 7, a ball bearing formed by a series of balls 8 and 9 ball cage, it further consists of a turning plate 10, the brake shoes 11, the brake segments 12 and the tension springs 13. The base 7 is fixedly connected to the lubricant 2, and on the base 7 by means of a center screw 14 which rotatable about its vertical axis insert 10 is fixed. The specified between the base 7 and the insert 10 accommodated ball bearing facilitates rotation. The ball bearing is formed by a series of balls 8 and ball cage 9, which is freely rotatable about the center screw 14 and is provided with the openings for accommodating balls. To the insert 10, the brake shoes 11 are attached, which also serves as a seat for the assembly of Binding 6 in the openings 21, and are provided with the brake segments 12. The brake shoes 11 are fixed to the insert 10 by means of the fixing screws 15, 16, 17 and 18 so that their vertical movement is minimized. In the vertical plane, the brake shoes 10 can rotate about the screws 15 at an angle which is limited by the movement of the screws 16, 17 and 18 in the oval openings 19 arranged in the insert. The insert 10 is further provided with a set screw 20 for adjusting the bias of the tension springs 13. The screws 16 also contribute to the brake segments 12. The tension springs 13 pull the brake shoes 11 to each other, and thereby they press the brake segments 12 to the cylindrical wall of the base 7 at. The pivoting platform 5 is therefore braked in this state in the specified location and allows a comfortable ride in the specified course. If the driver wants to change an orientation of the position, for example, when changing the course or performing a maneuver, tricks, etc., he develops a pressure with the heels from each other and with the tips to each other and thereby slightly rotates the brake shoes 11 in the mutually reversed direction, the brake segments 12 are detached and the driver can easily turn the pivotable platform 5 in the required position. Thereafter, the driver releases the pressure, so that the pivotable platform 5 is braked again by means of the force of the tension springs 13.

In Fig. 7, a mechanism of the safety connection of the pivotable platform 5 and the lubricant formed by snowboard 2 is shown. In this variant with the safety connection with the lubricant 2, this can Mechanism are constructed so that the base 7, a tube 27 is attached, which limits the height of the pivotable platform 5 above the lubricant 2, and at the same time carries other parts for connection with the lubricant 2. These are pressure springs 22, which press on the pressing elements 23, and which are slidably inserted into the openings in the opposite sides of the wall of the tube 27, and which on the inner side have a drop-out preventing flange and on the outer side an approximately hemispherical Having shape, by means of which in the formed on the inner sides of the strips 25 depressions 25A, which are mounted on the lubricant 2. A change in the adjustment of the contact pressure of the pressure springs is possible by means of a regulating screw 24 fastened to the base 7. The mechanism formed by the parts 22, 23 and 24 is a component of the base 7, and the strips 25 are to the lubricant 2 means the fastening screws 24 screwed. There may be a number of the indicated depressions 25A in the strips 25, which makes it possible to choose different positions of the pivotable platform 5 in the longitudinal axis of the lubricant 2.

To decouple the pivotable platform 5 and the lubricant 2 so it must come to press at least one of the pressing elements 23 in the tube 27, then the pressing member 23 can fail 25 of the recess 25A in the bar 25. For this purpose, it is necessary to overcome the pressing force of the pressing elements 23 in depressions 25A pressing force 22. This is in the situation when the attached to the pivotable platform 5 binding 6 and thus on the legs of the driver, for example, in his case, acting Torque rises above the set limit. The bias of the pressure springs 22, and thus also the decoupling of the pivotable platform 5 and the lubricant 2 required force can be changed by means of the adjusting screw 24.

In Fig. 8, the lubricant formed by snowboard with the pivotable platform with the safety connection and the rail for mounting the sail is shown. In Fig. 9, the lubricant formed by snowboard with the construction of the transverse and longitudinal beams is shown. In Fig. 10 is shown schematically the adjustment of the sail of the device according to the invention and the orientation of the position for different courses, where the arrow shows the wind direction. Furthermore, here are actual schematics of the layouts of the device in position to wind for actual courses shown: three left schemes with the courses "on starboard" - "front", "sideways" and "behind" three right schemes the same "on port" and the middle scheme for the "back" course.
