Description

Equipment for tobogganing for cross-country skis

Field of technology

The invention relates to a device for the tobogganing of cross-country skis, comprising a tubular frame connected to a seat and attachable to a ski binding, for use mostly in cross-country skiing and hiking.

Prior art

Cross-country skis are used for cross-country skiing and for hiking on snow. When hiking on cross-country skis in hilly terrain, it is sometimes necessary to descend to lower positions on an unpaved surface or on a surface suitable only for downhill skiing. In this case, normal cross-country bindings do not guarantee sufficient stability of the skier and there is a risk of injury. This applies in particular to descending forest roads with insufficient width, or icy or insufficiently groomed slopes. Often all that remains is to unclip the skis and walk down the slope, which can be a very difficult journey. EP 0 149 953 discloses embodiments of downhill skis which are connected in their front part by a connecting rod and in the rear part these skis are also connected and a seat with a backrest is placed on them. Although this design is comfortable for normal downhill skiing, it is not usable for cross-country skiing. The same is true in the solution according to document FR 2 573 660, where the robust seat is attached to the downhill skis and it is also possible to insert it into the binding of these skis. In the front part, these downhill skis are equipped with a footrest and are equipped with control levers. It is also possible to disassemble them. This construction is also comfortable for downhill skiing, but due to the complexity of this design it is not usable for cross-country skiing. GB 2 323 338 uses cross-country skis connected to a fixed seat provided at the front with short cylindrical protrusions insertable into a cross-country binding and at the rear with a short support. This design can be used for bobsleigh downhill, which requires some skills and the seat used must be solid, so they are uncomfortable to ski for cross-country skiing or hiking and the skier is soon tired due to the weight he has to carry. In addition, this device is difficult for an ordinary skier to operate.

The essence of the invention

It is therefore an object of the invention to provide a cross-country ski sledding device which is easy to carry, easy to assemble, safe and easy to operate.

The object is achieved by a solution according to the invention, the essence of which consists in that the device for sledding of cross-country skis, comprising a tubular frame connected to the seat and attachable to the ski binding, has a tubular frame formed by a front foot tube articulated to the rear foot. the front foot tube is placed in the front adapters for attachment to the clamping portion of the cross-country binding, the bodies of which conform to the shape of the clamping portion of the running shoes, and a screw is mounted above the front foot tube to secure the vertical position, and the rear foot tube is housed in rear adapters for support in the base plate of the running binding, comprising bodies located on the positioning and abutment plates, a screw being placed in the bodies above the rear foot tube to secure the vertical position.

The front adapters may be on the front foot tube and the rear adapters may be mounted on the rear foot tube.

The front adapters can be detachably mounted on the front foot tube and the rear adapters can also be detachably mounted on the rear foot tube.

- 1 CZ 306442 B6

Adjustable stops can be placed on the front foot tube and rear foot tube.

The cross-country ski sledge assembly can be mechanically strengthened by modifying the design of the rear adapters and modifying the base plate of the binding, which will allow a temporary firm connection of the rear adapters with the base plate of the cross-country binding.

To connect the seat to the cross-country skis, the two front adapters, which correspond in shape to the clamping part of the cross-country skis, are clamped in the binding of both skis. The front leg tube is then seated and secured in the front adapters so that each of the two adapters is located between two adjustable stops predetermined on the front leg tube. Furthermore, the two rear adapters are mounted on the rear foot tube so that each of the two adapters is located between two adjustable stops predetermined on the rear foot tube. After landing on the seat, both rear adapters rest and stabilize in position on the back of the base plate of the cross-country binding of both cross-country skis. Alternatively, the cross-country ski sled assembly can be further strengthened on site by mechanically connecting the rear adapters to the rear of the binding base plate.

The advantage of the sledge arrangement according to the invention is its low weight and small dimensions, especially when using a light tubular folding seat which weighs up to 1 kg and measures approx. 450 x 350 x 50 mm when folded, so that it can be easily attached to a small tourist backpack.

Examples of embodiments of the invention

The sledge adjustment according to Figs. 1 and 2 is performed on a pair of cross-country skis 6 and the device for performing this adjustment consists of a tubular frame 2, seat 3, front adapters 4, rear adapters 5 and adjustable stops 6. The front foot tube 9 is by means of front adapters 4 mounted in the clamping part 7 of the cross-country binding of both skis. The rear foot tube 12 is supported by the rear adapters 5 on the base plate 8 of the cross-country binding of both skis. The shape of the front adapters 4 corresponds to the shape of the cross-section of the cross-country ski boots and at the same time allows the front foot tube 9 to be attached. The shape of the rear adapters 5 corresponds to the specific design of the cross-country ski base plate 8 and also allows the rear foot tube 12 to be attached. fixed connection with the base plate 8 of the running binding. The screws £ 5 are used for this

-2GB 306442 B6 for firmly connecting the rear adapter to the guide rib 17 of the base plate 8 of the binding and the threaded holes in the guide rib 17 on the base plate 8 of the running binding. The mutual horizontal position of the front adapters 4 on the front foot tubes 4 and the rear adapters 5 on the rear foot tube 12 of the tubular frame 2 is defined by adjustable stops 6. To connect the tubular frame 2 to the cross-country skis 1, both front adapters 4, which correspond to the shape of the clamping part The front foot tube 9 is then seated in the recesses of the front adapters 4 so that each of the two front adapters 4 is located between two adjustable stops 6, which are pre-arranged on the front foot tube 9. the position of the front foot tube 9 is secured in both front adapters 4 by screws 11 for manual assembly / disassembly of adapters passing through the body 10 of the front adapter 4. Further, the rear foot tube 12 is seated in the recesses of the rear adapters 5 so that each of the two rear adapters 5 located between two pre-arranged adjustable stops 6 on the rear foot tube 12. The vertical position of the rear foot tube 12 adapters 5 secure screws 11 for manual assembly / disassembly of the rear adapters. After abutment on the seat 3, both rear adapters 5 rest and stabilize in position on the rear part of the base plate 8 of the cross-country binding of both skis 1. The body 13 of the rear adapter 5 is placed on the positioning and abutment part 14. The seat 3 is made of canvas, plastic or other of a material allowing easy articulation and opening of the tubular frame 2, on which this elastic seat 3 is placed in the upper part of the tubular frame 2. The positioning and abutment part 14 is connected to the body 13 of the rear adapter by a screw 18 for connecting the positioning and abutment part to the body of the rear adapter 5.

The equipment for tobogganing of cross-country skis significantly expands the possibilities of choosing hiking trails, for example to mountain ridges, from which it is often not possible to go downhill on classic tourist cross-country skis. Due to its low weight and small dimensions, this device is a suitable addition to equipment for cross-country hiking.
