Description

Safety Sled

The present invention relates to a sled, and more specifically, to the structure of a sitting sled.

In high latitudes, snow activities are loved by people. For the first time, sleigh rides are the simplest and safest choice.

Butterfly sleds usually have a smooth bottom and handlebars on the structure. Users can ride in the depression of the sled or sit down, and they can slide down towards the slopes to experience the pleasure of sliding. They are widely loved by all ages because of their simple operation. In view of this, the present inventors also gathered many years of practical experience in related fields, and continued to conceive of a riding sled.

According to the purpose of the present invention, a safety riding sled is provided, which includes a loading unit and a balance member. The loading unit includes a bottom plate and a side plate surrounding the bottom plate. The front side and the back side of the side plate along the forward direction form a forward and upward inclined front guide portion and a backrest portion higher than the front guide portion. The bottom plate has a central axis parallel to the forward direction, and A convex structure is formed along the central axis. The two balancing pieces are elongated, and are respectively arranged on the left and right sides of the side plate and parallel to the central axis of the bottom plate.

As a result, the surface below the floor that touches the snow presents a "V" -shaped structure that begins with the center axis of the floor, and a smooth ski trail runs on the sloped snow along the direction of the slope.

Preferably, the loading unit may include a reinforcing structure, for example, a reinforcing structure protruding substantially parallel to the central axis of the bottom plate on the top surface of the bottom plate, and a reinforcing structure protruding substantially perpendicular to the central axis of the bottom plate on the bottom plate, The backrest portion includes a raised reinforcement structure for adjusting the center of gravity configuration of the loading unit, making it safer in operation, and providing a position of leaning on both feet when the user is riding the loading unit.

Preferably, the cross-section of the convex structure of the bottom plate has a tapered shape with an apex angle at an obtuse angle, thereby facilitating the opening of a passage in the snow.

Preferably, the leading portion is an arc-shaped structure protruding along the advancing direction, and when the loading unit is inclined by gravity, it slides down the slope.

In order to clearly illustrate the specific implementation, structure, and effects achieved by the present invention, the illustrations are as follows: Please refer to FIGS. 1 to 3. In the figure, a riding sled includes a riding unit and two sides of the riding unit. Balance piece 50.

The loading unit includes a bottom plate 11 and a side plate 12 surrounding the periphery of the bottom plate 11. The side plate 12 forms a front guide portion 121 and a high backrest portion 122 from front to back along the advancing direction of the sled, wherein the backrest portion 122 forms a groove shape. Whereas the user can sit on the back and rely on his back, the front guide 121 serves as a position where the user can step on.

According to this embodiment, the shape of the backrest portion 122 is approximately a rectangular parallelepiped, and the height of the backrest portion 122 is about half of the height of the back when the user's buttocks sit on the bottom plate 11 in a general body proportion. The front-to-back distance from the front guide portion 121 to the backrest portion 122 causes the user's back to tilt back. When the feet are bent about 60-90 degrees, the sole of the foot can be placed flat on the length of the front guide portion 121. The front guide 121 is inclined outward toward the forward direction of the riding sled, allowing the user to lean back slightly when riding, which is comfortable and safe.

The two balance pieces 50 are respectively arranged on the left and right sides of the side plate 12 along the advancing direction of the sitting sled and are parallel to the central axis of the bottom plate 11. As the wings of the sitting sled, they are used to assist balance, have the function of preventing overturning, and improve safety . According to this embodiment, the balance member 50 is cylindrical. However, the shape of the balance member 50 is not limited to this. The cross-sectional shape may be any geometric figure, such as a rectangle, a triangle, or other polygons. In other embodiments, The bottom of the balance member 50 may be a spindle type with the arc surface facing downwards, thereby reducing friction with snow.

According to this embodiment, the top surface of the bottom plate 11 further includes a first reinforcing structure 15 protruding substantially parallel to the central axis 13 (as shown in FIG. 4) of the bottom plate 11. In addition to focusing the center of gravity of the sitting sled, The user's feet are separated on both sides of the bottom plate 11 and the front guide 121.

In other embodiments, the first reinforcing structure 15 of the bottom plate 11 may also add a portion (not shown) that is perpendicular to the central axis of the bottom plate 11. For example, the first reinforcing structure 15 is located near the center of the bottom plate 11 and has a peak shape. Provides legs for relaxation and relaxation.

In addition, the backrest portion 122 includes a second reinforcing structure 16 protruding inward, and the second reinforcing structure 16 is provided with a concave arc-shaped surface, which makes the user more comfortable when leaning in a sitting position. In other embodiments, a buffer member is further provided on the second reinforcing structure 16 to reduce the buffering force transmitted to the user during coasting. In addition, the side plate 12 includes an auxiliary member 60 to increase the safety during sliding. For example, two sides of the side plate 12 may be provided with handles for holding, and the backrest portion 122 may be provided with a safety belt.

Another feature of the present invention is the structural design of the bottom plate 11 of the loading unit. Please refer to FIG. 4. In the figure, the other side of the bottom plate 11, that is, the bottom of the loading unit that is in contact with snow, is included in the central axis 13 of the bottom plate 11. A convex structure 14 is raised, and the surface contacting the snow below the bottom plate presents a "V" -shaped structure that starts from the center axis of the bottom plate and is used to cut through the snow to generate a passage.

According to this embodiment, the central axis of the base plate 11 is substantially perpendicular to the front guide portion 121 and the backrest portion 122, and the convex structure 14 is convex on the central axis of the base plate 11 and gradually flattens toward the outer edge of the base plate 11. For example, the design is convex The cross section of the structure is a tapered cone with an apex angle at an obtuse angle. When the structure is sliding on a snowy slope, the "V" shaped structure runs a smooth ski track along the direction of the slope. In other embodiments, the two sides of the “V” -shaped structure may be inwardly concave or outwardly convex structures, so as to generate appropriate resistance in snow.

According to this embodiment, the bottom of the balance member 50 and the bottom of the sitting sled are not on the same plane. When the bottom of the sitting sled sinks into the snowdrift, the bottom of the balance 50 is still higher than the snow surface. Therefore, when sitting When the sled is slanting away from the central axis 13, the balance member 50 can contact the snow surface without accidental overturning, thereby improving safety. However, the bottom of the balance member 50 may also be at the same height as the snow surface or the bottom of the riding unit, and at the same time, it forms a supporting part of the riding unit together with the bottom of the sitting sled.

According to this embodiment, the front guide portion 121 is inclined outward in the forward direction of the riding sled, resulting in a slightly warped structure in front of the riding unit, so that the riding unit slides down the slope. In addition, the leading part has an arc-shaped structure that protrudes forward and downward along the forward direction. It can also slide down the slope when the load unit is under the force of gravity. The maximum length is 150-200 meters. far.
