Description

The utility model relates to vehicles on snowy and icy surfaces, in particular, to sledges designed for skiing from mountains and movement on a horizontal surface, as well as for transportation of household goods in the winter. In addition, sledges can be used for rescue purposes if it is necessary to transport people on snow and ice.

Inflatable sledges are known, comprising a body made in the form of an inflatable element that is housed in a case, the case having an opening for accommodating an inflatable balloon closed with a zipper or Velcro, RU 63308 U1 05.27.2007.

The disadvantages of these sleds include the fact that lightning under a load acting perpendicular to the surface of the sled is affected by a large force, which causes the opening and / or breaking of the lightning; in addition, when the user lands, the center of gravity is located quite high above the rolling surface, which can lead to loss of balance, capsizing of the sled and injury to the user and / or others.

Inflatable sledges are known, comprising a body including an elastic inflatable element housed in a case with a hole; the hole is located in the upper half of the cover, the cover is equipped with a flexible element located around the perimeter of the hole and forming a concave parabolic seat, a device for reducing the size of the hole is placed on the outer edge of the flexible element, RU 104912 U1 05/27/2011.

The disadvantage of this device is the presence of a hole in the upper half of the cover, which does not completely close, as a result of which snow, rain, etc. can get inside the sleigh.

Inflatable sledges are known comprising a body including a cover with an opening and an inflatable element housed in the cover; the inflatable element has the shape of a torus, the hole is made in the upper half of the cover above the hole of the inflatable element, and the center of the hole is at an equal distance from the edges of the sled body, RU 104913 U1 05/27/2011.

The disadvantage of this technical solution is that the cavity of the cover is completely open from above, and a large amount of snow, water can get into it with the formation of ice, which is traumatic; in addition, the seat, essentially, is the edge of the hole in the upper part of the cover, which is inconvenient in operation. If the size of the hole is too large for a specific user, for example, a child, then he will fail and will sit on the bottom of the cover, which is very dangerous if there are solid sharp elements on the sliding surface.

Sledges are also known, comprising a carcass consisting of an elastic inflatable member housed in a case with a hole; the cover has a seat in the form of a hemisphere concave downward, RU 128170 U1 05/20/2013.

The hole in the upper part of the cover and, accordingly, the hemisphere diameter should be at least 35-40 cm, even when used by their children and adolescents. In this case, the hemisphere radius, respectively, will be 17.5-20 cm. However, the height of the sleigh is usually not more than 25-30 cm, since an increase in the height of the sleigh will lead to an increase in their weight, which will complicate their operation, and also to increase material consumption, which will increase the cost of the sleigh. With the generally accepted height of the sleigh of 25-30 cm, the implementation of the seat in the form of a hemisphere leads to the fact that the distance from it to the sliding surface is 5-12 cm, and when landing in the sleigh of the child, this distance is minimal. Thus, the implementation of the hemisphere-shaped seating can lead to injuries when riding on a surface on which there are bumps and protrusions visible or hidden under the snow, especially sharp ones.

Inflatable sledges are known, comprising a body made in the form of an inflatable element housed in a case with an opening in its upper part intended to be inserted into the case of an inflatable element. With the edges of the hole, a seat is made of flexible material, divided into two parts with the possibility of pairing for overlapping holes facing each other of the edges of both parts, made with an overlap of one part to another, RU 111829 U1 12/27/2011.

This technical solution was made as a prototype of this utility model.

The disadvantages of the prototype are as follows.

Overlapping the hole in the cover only due to overlapping edges of the parts of the seat does not prevent the ingress of rain and foreign objects into the sleigh even without load, since there are sufficiently large gaps between the parts of the seat from flexible material; under load, the edges of the parts of the seat can diverge even more significantly, which, in addition to precipitation and foreign objects, causes the lowering of the load (person, load) in the direction of the rolling surface, as a result of which mechanical contact with bumps and protrusions on this surface is possible. As a result of this, serious injuries or damage to the load when moving the sled are possible.

The objective of this utility model is to prevent the divergence of the edges of the parts of the seat and, thereby, reduce the ingress of rainfall and foreign objects into the sleigh; In addition, the task of improving operational safety is being addressed.

According to a utility model, in an inflatable sled containing a body made in the form of an inflatable element placed in a case with an opening in its upper part, with which a seat is made of flexible material, divided into two parts, with the possibility of their docking to close the opening, while the edges of the parts of the seat facing each other are made with an overlap of one part on the other, a strip of flexible durable material is attached to the cover under the seat; a strip of flexible durable material is located in the center of the hole in the cover perpendicular to the edges of the parts of the seat.

The applicant has not identified any technical solutions identical to the claimed one, which allows us to conclude that the utility model meets the patentability condition “Novelty”.

The essence of the utility model is illustrated by drawings, which depict:

in FIG. 1 is a plan view;

in FIG. 2 is a section A-A in FIG. 1, pens are not shown conditionally;

in FIG. 3 - device in a perspective view. Inflatable sledges contain a housing made in the form of an inflatable element 1, in this example, a rubber automobile camera. The inflatable element 1 is placed in a cover 2 made of polyvinyl chloride material. In the case 2, a hole 3 is made in its upper part. A hole 3 is associated with a seat made of flexible material, in particular, Oxford fabric with a density of 600D. The seat is made of two parts 4, 5 with the possibility of their joining to overlap the holes, while the edges of the parts 4, 5 facing each other are overlapped with one part to another. A strip 6 of flexible flexible material is attached to the cover 2 under the seat, in this example, of woven material with mylar threads. The strip 6 is located in the center of the hole 3 in the case 2 perpendicular to the edges of the parts of the seat. The sleigh is equipped with handles 7 of flexible material attached to the cover 2. For transporting the sleigh, a towing belt 8 is used (shown only in Fig. 3).

The device operates as follows. To open the hole 3 in the cover 2, the edges of the seats 4, 5 are bred to the sides, between which the inflatable element 1 is introduced into the cover 2 through the hole 3 and then inflated with a pump or compressor to a predetermined air pressure value. After that, they overlap the edges of parts 4, 5 of the seat. Hole 3 is thus blocked. Parts 4, 5 of the seat are supported by strip 6. The result is a technical result consisting in preventing the divergence of the edges of parts 4, 5 of the seat, and thereby reduce the ingress of rain and foreign objects into the sleigh; an additional technical result is also achieved: the operation safety of the device is increased, since the sagging of the seat under load is prevented, and thereby the contact of a seated person or cargo with uneven surfaces is excluded.

The sled is installed on a snowy or icy surface, the user sits on the seat, while he can hold the handles during movement 7. Moving the sled with or without load is carried out by the towing belt 8.

The applicant manufactured and successfully tested a prototype device.
