Description

Technical Field

[0001] The invention relates to a ski support and a ski device. Background Art

[0002] Natural ski resorts are limited by temperature and seasons, and the maintenance cost is relatively high. They cannot meet the sports needs of ski enthusiasts in a timely manner. Therefore, artificial ski equipment is applied. Traditional artificial ski equipment generally includes a mounting seat and a ski support member arranged on the mounting seat. The ski support member includes a mounting bar and a plurality of support columns spaced along the length direction of the mounting bar. A ball head is arranged at the upper end of the support column. The upper end points of all ball heads are located on the same plane to support the ski equipment on the feet of the skier.

[0003] When a skier needs to brake during dry skiing, he usually squats down and tilts the outer side of the ski downward to act on the support. At this time, the support column produces elastic deformation, and the outer side of the ski contacts the junction of the ball head and the support column and then separates from the ball head, thereby achieving the purpose of braking.

[0004] Traditional ski supports, while meeting certain braking effects, have relatively large sliding resistance, resulting in a shorter sliding distance, which affects the skiing experience. Summary of the invention

[0005] In order to overcome the shortcomings of the prior art, one of the objects of the present invention is to provide a ski support component that reduces sliding resistance, increases sliding distance, and has a longer wear life while ensuring braking performance. The second object is to provide a ski device using the above-mentioned ski support component.

[0006] According to the first aspect of the present invention, the ski support device comprises: a mounting bar, wherein a plurality of elastic support columns extending upward are arranged at intervals along the extension direction of the mounting bar, a large head is provided at the upper end of the elastic support column, a small head is provided above the large head, and the upper part of the small head has an arc-shaped supporting surface.

[0007] The ski support according to the embodiment of the present invention has at least the following beneficial effects:

[0008] The above ski support is provided with a large head at the upper end of the elastic support column, a small head is provided above the large head, and an arc-shaped supporting surface is provided on the upper part of the small head. When braking is required, the ski equipment tilts sideways and acts downward on the ski support, the elastic support column undergoes elastic deformation and makes the ski equipment contact the junction of the large head and the elastic support column, thereby achieving a braking effect; when the ski equipment slides on the ski support, the ski equipment contacts the arc-shaped supporting surface on the small head, and the contact part of all the arc-shaped supporting surfaces and the ski equipment constitutes a supporting surface for supporting the ski equipment. The friction resistance of the supporting surface is small, so that the ski equipment slides more smoothly and the sliding distance is increased; and the use of the large head for braking and the small head for sliding can increase the wear life of the ski support.

[0009] In some embodiments of the present invention, the surface of the large head and the surface of the small head have at least a partial spherical surface or an ellipsoidal surface.

[0010] In some embodiments of the present invention, the surface of the large head is a first spherical surface, the surface of the small head is a second spherical surface, and the diameter of the first spherical surface is greater than the diameter of the second spherical surface.

[0011] In some embodiments of the present invention, the large head is in the shape of a spherical segment, the small head is connected to the upper end of the large head, and the small head is in the shape of a spherical crown.

[0012] In some embodiments of the present invention, a first transition groove is provided between the lower end of the large head portion and the upper end of the elastic support column.

[0013] The elastic support column is a cylinder. In the radial direction of the elastic support column, the radial dimension of the large head is larger than the radial dimension of the elastic support column. The arc transition between the lower end of the large head and the outer circumferential surface of the upper part of the elastic support column defines the first transition groove.

[0014] In some embodiments of the present invention, the large head is a first cylinder, and the small head is a second cylinder disposed on the upper end surface of the first cylinder.

[0015] In some embodiments of the present invention, the elastic support column, the large head and the small head are an integral plastic structure.

[0016] A skiing device according to an embodiment of the second aspect of the present invention comprises a skiing support member of any of the above-mentioned schemes. The skiing device using the skiing support member not only ensures the braking effect, but also reduces the sliding resistance, so that the skiing equipment slides more smoothly and increases the sliding distance, and the skiing device has high durability.

[0017] In some embodiments of the present invention, the ski device includes a plurality of mounting bases that can be spliced ​​into one body, the mounting bases are provided with a plurality of strip-shaped mounting grooves that are spaced apart in parallel, and the mounting strips are detachably mounted in the strip-shaped mounting grooves.

[0018] Additional aspects and advantages of the present invention will be given in part in the following description and in part will be obvious from the following description, or will be learned through practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0030] Reference Figure 1 , Figure 2 and Figure 6 The ski support of the present invention comprises: a mounting bar 100, a plurality of elastic support columns 200 extending upward are arranged at intervals along the extending direction of the mounting bar 100, a large head 300 is arranged at the upper end of the elastic support column 200, a small head 400 is arranged above the large head 300, and the upper part of the small head 400 has an arc-shaped supporting surface. It should be noted that the small head 400 is smaller in volume than the large head 300, and generally speaking, the vertical projection of the small head 400 is located within the vertical projection of the large head 300.

[0031] The above ski support has a large head 300 at the upper end of the elastic support column 200, a small head 400 above the large head 300, and an arc-shaped support surface on the upper part of the small head 400. When braking is required, the ski equipment tilts and acts downward on the ski support, the elastic support column 200 undergoes elastic deformation and makes the ski equipment contact the junction of the large head 300 and the elastic support column 200, thereby achieving a braking effect; when the ski equipment slides on the ski support, the ski equipment contacts the arc-shaped support surface on the small head 400, and the contact part of all the arc-shaped support surfaces and the ski equipment constitutes a support surface for supporting the ski equipment. According to the experiment, the friction resistance of the above structure is small, so that the ski equipment slides more smoothly and increases the sliding distance; and the large head 300 is used for braking and the small head 400 is used for sliding, which can increase the wear life of the ski support. It should be noted that in the sliding state, the tops of the arc-shaped support surfaces on all the small heads 400 are all located on the same height plane, which is the above support surface.

[0032] In order to verify that the frictional resistance of the ski support of the present invention on the ski equipment is less than the frictional resistance of the conventional ski support on the ski equipment, the following comparative test is given:

[0033] Two mutually parallel conventional ski supports are installed at intervals on the mounting base (the conventional ski support only has a large head 300 provided on the upper end of the elastic support column 200, and does not have a small head 400), and then the mounting base with the conventional ski support is inverted on the test platform so that the small head on the ski support is in contact with the surface of the test platform, a 5N weight is placed on the mounting base, and a tension testing instrument is used to pull the mounting base with the conventional ski support to move at a constant speed. The above test method is used for 6 consecutive tests to obtain a set of tension data, which is the friction resistance of the conventional ski support on the ski equipment.

[0034] Then, two mutually parallel ski supports of the present invention are installed at intervals on another mounting base, and then the mounting base with the ski supports of the present invention is inverted on the test platform so that the small head of the ski supports contacts the surface of the test platform, a 5N weight is placed on the mounting base, and the mounting base with the ski supports of the present invention is pulled by a tension testing instrument to move at a constant speed. The above test method is used for continuous testing 6 times to obtain another set of tension data, which is the friction resistance of the ski supports of the present invention on the ski equipment. The following are two sets of tension data for the comparative test:

[0035]

[0036] It can be seen that the frictional resistance of the ski support of the present invention on the ski equipment is smaller than the frictional resistance of the conventional ski support on the ski equipment.

[0037] In some embodiments of the present invention, in order to allow the ski to stop smoothly during braking and avoid the large head 300 and the small head 400 causing the ski to bounce, the surface of the large head 300 and the surface of the small head 400 have at least a partial spherical or ellipsoidal surface, which can contact the ski.

[0038] For details, see Figure 3 In some embodiments, the large head 300 and the small head 400 are both irregularly shaped, and both the large head 300 and the small head 400 have a partial spherical surface, and the spherical surfaces of the large head 300 and the small head 400 are both facing the direction in which the skier approaches the ski support.

[0039] For details, see Figure 4In some embodiments, the large head 300 is a first ellipsoid, the small head 400 is a second ellipsoid formed on the first ellipsoid, the volume of the second ellipsoid is smaller than the volume of the second ellipsoid, and the vertical projection of the second ellipsoid is within the range of the vertical projection of the first ellipsoid.

[0040] See also Figure 2 In some embodiments of the present invention, the surface of the large head 300 is a first spherical surface, the surface of the small head 400 is a second spherical surface, and the diameter of the first spherical surface is greater than the diameter of the second spherical surface. It should be noted that when braking is required, the skier squats and makes the skiing equipment act downward on the ski support. Generally speaking, the bottom of the skiing equipment is tilted laterally and pressed against part of the ski support. The elastic support column 200 is elastically deformed so that the side wall of the large head 300 contacts the bottom of the skiing equipment. In the process of the skiing equipment first contacting and then separating from the ski support, the skiing equipment contacts the first spherical surface and the second spherical surface in turn. The surface of the large head 300 is the first spherical surface and the surface of the small head 400 is the second spherical surface, which is conducive to smooth braking, and can avoid the large head 300 and the small head 400 from causing serious interference with the movement direction of the skiing equipment, so that the skiing equipment slides more smoothly.

[0041] See also Figure 2 In some embodiments of the present invention, the large head 300 is in the shape of a spherical segment, the small head 400 is connected to the upper end of the large head 300, and the small head 400 is in the shape of a spherical crown. When the skier needs to stop while sliding in any direction, the large head 300 and the small head 400 of the above structure can ensure that the ski equipment can stop smoothly, avoiding the phenomenon of the ski equipment jumping. Moreover, the connection strength between the large head 300 and the small head 400 is relatively high, which improves the service life of the ski support.

[0042] In some embodiments of the present invention, a first transition groove 510 is provided between the lower end of the large head 300 and the upper end of the elastic support column 200. It is understandable that when braking is required, the skier operates the bottom of the skiing device to tilt sideways to act on the support member, and the side edge of the bottom of the skiing device first contacts the elastic support column 200, and then passes from the upper end of the elastic support column 200 through the lower end of the large head 300. The provision of the first transition groove 510 can accelerate the attenuation of the kinetic energy of the skiing device, making the braking more rapid.

[0043] In some embodiments of the present invention, the elastic support column 200 is a cylinder, and in the radial direction of the elastic support column 200, the radial dimension of the large head 300 is greater than the radial dimension of the elastic support column 200, and the arc transition between the lower end of the large head 300 and the outer circumferential surface of the upper part of the elastic support column 200 defines the first transition groove 510. The arc transition between the lower end of the large head 300 and the outer circumferential surface of the upper part of the elastic support column 200 helps the ski equipment to smoothly pass through the junction of the elastic support column 200 and the large head 300, thereby improving the stability of the brake stop operation.

[0044] See also Figure 5 In some embodiments of the present invention, the large head 300 is a first cylinder, and the small head 400 is a second cylinder disposed on the upper end surface of the first cylinder. It can be understood that during the sliding process, the bottom of the ski equipment contacts the top wall of the second cylinder, and when the ski equipment needs to stop, the bottom of the ski equipment contacts the side wall of the first cylinder. The ski support of this structure is easy to produce and process.

[0045] See also Figure 1 and Figure 2 In some embodiments of the present invention, in order to simplify the production process and ensure the structural strength and elastic performance of the ski support, the elastic support column 200, the large head 300 and the small head 400 are an integrated plastic structure. The ski support having the elastic support column 200, the large head 300 and the small head 400 can be obtained by integrated injection molding.

[0046] See also Figure 1 In some embodiments of the present invention, in order to facilitate the removal and installation of the ski support and to facilitate the application of the ski support to the ski device, a plurality of plug-in components 600 are arranged at intervals along the length direction of the bottom of the mounting bar 100 .

[0047] See also Figure 6 A skiing device according to an embodiment of the second aspect of the present invention comprises a skiing support member of any of the above schemes. A skiing device comprising a skiing support member of any of the above schemes. The skiing device using the skiing support member not only ensures the braking effect, but also reduces the sliding resistance, so that the skiing equipment slides more smoothly and increases the sliding distance, and the skiing device has high durability.

[0048] See also Figure 6In some embodiments of the present invention, the ski device includes a plurality of mounting bases 10 that can be spliced ​​into one body, and a plurality of parallel and spaced strip mounting grooves 11 are provided on the mounting base 10, and the mounting strips 100 can be detachably mounted in the strip mounting grooves 11. The plurality of mounting bases 10 can be freely spliced ​​in different directions according to the needs of use, so as to obtain a dry skiing field, and the manner in which the mounting strips 100 can be detachably mounted in the strip mounting grooves 11 simplifies the production and assembly of the ski device, and is convenient for use.

To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
