Description

Technical Field

[0001] The utility model relates to winter equipment used for winter sports, in particular to a device moving on a snow surface. Background Art

[0002] Existing snowboards and snowskates (models Burton, Ambition, etc.) are designed specifically for downhill skiing. The main disadvantages of these devices are that the snowboards are provided with foot fixing devices, which increase injuries and inconveniences when used, and because there is only one snowboard, the stability is insufficient and the adhesion to the snow is poor.

[0003] The closest prior art to the present invention is a snowboard (patent number RU2344864), which includes two parallel snowboards connected to each other by a mechanical connector so that the snowboards are parallel to each other, a footboard is divided into two footboards in a transverse plane, each footboard is used to fix a boot, and the footboard is equipped with at least two mechanical elements, which are knee-shaped levers, and the knees of which are connected to the footboards by cylindrical hinges. The two ends of each lever are connected to the same side edge of different snowboards in pairs by cylindrical hinges, wherein the axes of the paired pairs are parallel to each other.

[0004] The splitting of the footrest into two parts complicates the design of the device and the connection thereto causes inconvenience and unnecessary trauma. The cylindrical hinge connecting the curved arms prevents the ski from following the terrain. In addition, the known device does not have a return mechanism with adjustable stiffness. Another disadvantage of the prior art device is that there is no carving radius on the ski, so carving (in an arc) cannot be performed. Utility Model Content

[0005] The problem that the utility model aims to solve is to facilitate use, reduce damage and improve maneuverability.

[0006] The technical effect achieved by the present application is to improve the maneuverability of a device moving on snow.

[0007] The technical solution adopted by the utility model to solve the technical problem is: in the known device, it includes two parallel skis and a foot pedal equipped with a knee-shaped lever, the knee of the lever is connected to the foot pedal in pairs, and the end of each lever is connected to the same side edge of different skis through a hinge. The utility model provides the following content: the foot pedal is made in one piece and connected to the knee of the lever, and the end of each lever is connected to the same side edge of different skis in pairs through a spherical hinge, and the ski is provided with a carved radius. Further, the device is also provided with a reset mechanism with adjustable stiffness, which is composed of two vertical threaded shafts, each of which is provided with a mute block and an adjusting nut mounted thereon, and the threaded shafts are respectively mounted at the center of the ski and connected to each other through a cross plate, and the cross plate is connected to the foot pedal through a spherical hinge, and the spherical hinge is close to any pair of the knee-shaped levers.

[0011] Figure 1 It is a schematic diagram of the main components of the utility model.

[0012] The device comprises a footrest 1 and a snowboard 2 placed parallel to each other. The footrest 1 is connected to the snowboard 2 via two knee-shaped levers 3, each end of which is connected to the snowboard 2 via a ball joint 4. The resetting mechanism with adjustable stiffness comprises two vertical threaded shafts 7. The threaded shafts 7 are provided with a mute block 5 and an adjustment nut 6 mounted thereon. The threaded shafts 7 are connected to each other via a cross plate 8, which is connected to the footrest 1 via a ball joint 4.

[0013] Figure 2 Schematic diagram of an arrangement of a snowboard 2 having a carved radius.

[0014] Figure 3 Schematic diagrams of the device in static and motion states are shown.

[0015] When the device moves on the snow, in order to turn, the athlete, who stands freely on the footrest, must transfer his center of gravity along the axis of movement to the edge of the footrest 1 to tilt it. The snowboard 2 tilts with the footrest 1 and enters the radius of the carving, and will continue to move along this radius. During the movement of the device, when the athlete involuntarily tilts to either side along the axis of movement of the device, the footrest 1 will also tilt accordingly, the device will move under the athlete and the tilt will be leveled. The presence of a ball hinge allows the necessary decoupling between the snowboard 2 and the footrest 1, so as to have an optimal adaptability to the sliding terrain of the snowboard 2, as well as enabling the snowboard 2 and the footrest 1 to bend in different directions, thereby improving the adhesion of the snowboard 2 to the sliding slope and increasing the life of the device.

[0016] For specific missions, the number of skis 2 can be increased to 3 or more.
