RU60380U1 - DEVICE FOR ROLLER SKATING IN WINTER CONDITIONS - Google Patents

Abstract

The utility model relates to sports equipment. The proposed utility model solves the problem of creating a device for roller skating in winter conditions for extreme skiing. In a device for roller skating in winter conditions, including a frame and ski, the front and rear ski has an arched spherical surface and does not protrude from the front and rear frame more than 6 cm, the sliding surface of the ski consists of a profiled middle section having guide runners along the edges and a sample in the middle part, with the end and nose of the ski having a narrowing of the middle part, and the frame and the ski can be made non-releasable. The ski can be made of various materials: wood, plastic. It is also possible to produce frames with whole skis for replacing the frame with rollers on a frame for winter skiing (not shown in the drawing). The device for inline skating in winter conditions provides safe inline skating in winter conditions, technologically advanced in production, convenient in operation. Allows athletes to engage in extreme roller-skating - rollerblading in the winter. The use of this device allows you to expand the boundaries of rollerblading, i.e. allows you to ride where there are no indoor skateparks, but there is a cover of snow.

Description

The utility model relates to sports equipment.

Known shoe according to patent US 3983643, suitable for walking and for rollerblading.

US Pat. No. 3,884,485 describes a skate with retractable rollers, the casing of which is adapted to be attached to the boot, and a plurality of rollers are rotatably supported on the retractor and retracted into the casing.

Patent 4333249 describes a device convertible for sports use. The device is a roller skate, fixed between two positions by means of rotary levers, made with the possibility of their fixing between the retracted position and the position of rolling on the rollers.

Known shoe with retractable rollers according to patent No. 2114670 (publ. 07.10.98), including front and rear rollers, made with the possibility of movement between the first position of contact with the ground and the second raised position, and the front and rear rollers are interconnected with at least one link skipped inside the sole, with the aim of simultaneously moving the front and rear rollers using means for pulling connected to the specified flexible connecting link.

The disadvantages of these solutions is the inability to use these structures for extreme skiing in the winter season.

Known boot for aggressive skiing, according to patent FR 2833180 (publ. 2003.06.13) including a frame and skis.

The disadvantage of this solution is the inconvenience in operation in extreme skating - rollerblading. Skis of this design break quickly, because the load when jumping on the protruding parts of the side, front

and the back is large, there is a great danger of injury to athletes, because there is a chance that the toe and heel of the skis can catch on an obstacle after jumping to the ground from the railing and from the ground to the railing. The use of skis wider than the frame for roller skates interferes with simple skiing and gliding along the railing. The device for winter extreme skiing is inconvenient to use, bulky.

The proposed utility model solves the problem of creating a device for roller skating in winter conditions for extreme skiing.

To achieve the specified technical result in the device for rollerblading in winter conditions, including a frame and ski, the front and rear ski has an arched spherical surface and protrudes beyond the frame front and rear by no more than 6 cm, the sliding surface of the ski consists of a profiled the middle section, with guide runners along the edges and a sample in the middle part, with the end and nose of the ski narrowing in the middle part, and the frame and ski can be made integral

The distinctive features of the proposed device for rollerblading in winter conditions from the above, the closest one is that the ski front and rear has an arched spherical surface and protrudes beyond the frame in front and behind by no more than 6 cm, the sliding surface of the ski consists of a profiled middle section having guide rails along the edges and a sample in the middle part, with the end and nose of the ski narrowing in the middle part, and the frame and ski can be made integral

Due to the presence of these signs, a device was created for inline skating in winter conditions, the boundaries of “roller blading” were expanded, i.e. it becomes possible to ride where there are no indoor skateparks, but there is a cover of snow.

The proposed design is illustrated by the drawings shown in figures 1-4.

Figure 1 shows a shoe with a frame for roller skates designed for aggressive roller skating;

Figure 2 shows a boot with a frame with interchangeable skis;

Figure 3 shows a frame with interchangeable skis;

Figure 4 shows a section aa

Figure 5 shows a view along arrow B.

A device for roller skating in winter conditions (figure 2), is a frame 1, which is mounted on boots for roller skating (figure 1) The frame 1 for extreme roller skating has grooves 2 under the pipe for skiing railing. For training in the winter season, it is necessary to find a replacement for rollers 3 (Fig. 1) - a device for roller skating in winter conditions. The proposed device is a ski 4 (figure 3) having a sliding surface 5 with a profiled middle section 6 (figure 3), having guide rails 7 along the edges and a sample 6 in the middle part for ease of sliding and a quick set of the required speed. The ski (Fig. 3) consists of 2 parts: front 8 and rear 9, which are placed in the frame, respectively, front and rear. The ski (figure 4) has a protrusion 10 on the upper platform, the size of the protrusion is selected so that it follows the shape of the groove 11 of the frame of the roller skates. The protrusion of the ski is inserted into the groove of the roller skates and fixed by fasteners 12 in the place where the rollers were previously attached (figure 4). The ski protrudes in front and behind the frame by the same L value (Fig. 2) as the rollers, but no more than 6 cm, which preserves the usual riding conditions for athletes and reduces injuries. Skis front and rear have an arched spherical surface with flat sidewalls having a narrowing in the middle part for ease of skiing (figure 5). The ski has a width equal to the width of the frame or slightly greater than the width of the frame. The nose of the frame is mounted on the boot flush with the toe of the boot, and the back of it is flush with the back of the boot, and the skis respectively extend beyond the heel and toe of no more than 6 cm. When the ski protrudes more than 6 cm relative to the boot and frame falling athletes and ski breaks.

The ski has a rounded front and rear, and the rounding in its upper part closes the groove of the frame from the ingress of snow. The rounding of the ski front and rear is made in an arcuate shape with flat side parts having a narrowing in its middle part, and the side parts protect the frame from snow and freezing

ice, and also repeat the roller contour habitual for the athlete, which allows you to perform complex tricks without retraining the athlete after the usual winter skating rollers on the proposed device.

The ski can be made of various materials: wood, plastic. It is also possible to produce frames with whole skis for replacing the frame with rollers on a frame for winter skiing (not shown in the drawing).

The device for inline skating in winter conditions provides safe inline skating in winter conditions, technologically advanced in production, convenient in operation. Allows athletes to engage in extreme roller-skating - rollerblading in the winter. The use of this device allows you to expand the boundaries of rollerblading, i.e. allows you to ride where there are no indoor skateparks, but there is a cover of snow.
