Definitions

• the present invention refers to a roller ski for training long distance skiing and of the type incorporating a foot plate with binding means adapted to retain the users' ski shoe in such a manner that its heel portion is freely pivotable about the firmly fixed toe portion, and which foot plate is supported by a front and a rear wheel, whereby supporting members are arranged to extend upwards from the foot plate in order to form side supports for the users' lower leg.
• Roller skis of the type mentioned hereabqve are wellknown aids for making possible training adapted to long distance skiing also when snow is missing.
• roller skis are designed in such a manner that they can only be used on a very smooth and even surface, preferably asphalted roads. It is of course less convenient that training and excersing skiing must take place in close vicinity to the road traffic, and furthermore often at dusk or even in darkness, which means great risks for traffic accidents and furthermore a not very healty environment for the roller skier, who will have to inhale exhaust-mingled air.
• roller skis are delimited to asphalted roads and the like.
• they for reaching a sufficient side-stability is equipped with small, broad wheels, which is necessary in order not to expose the skiers' ankles to very large lateral bending stresses.
• This design means that the roller ski will behave essentially as an ordinary ski which has rather small tendencies of wobbling laterally.
• roller skis having larger wheels, but these roller skis have been provided with binding means which have kept the ski boot in a fixed position, whereabove it has also been necessary to use stiff down-hill race boots in order to obtain a sufficient stability in order to have strength enough to balance the tendencies of side tilting. It has indeed been possible to use this type of roller ski in the terrain due to its large wheels, but due to the firm arresting of the ski boot has its use been limited to slope running or for long distance skiing with use only of the sticks and without use of the legs.
• the purpose of the present invention is to provide a roller ski for eross-country-skiing-like training or excercising, the use of which is not delimited to even and smooth surfaces and this is obtained thereby that the roller ski according to the invention is provided with supporting members which are formed by rigid side members which extend one of each side of the foot plate in arc-form upwards from the foot plate between its forward and rear portions for providing, during the pivoting of the heel portion around the binding means lateral supports, at a level just above the ski shoe along the entire motion path of the lower leg, without thereby holding or hampering the leg in its motion in the longitudinal direction of the roller ski.
• roller ski according to the invention with pneumatic rubber wheels, which can be used e.g. on forest pahaths, on prepared electriclight-illuminated snow-free tracks etc.
• Figure 1 shows in a schematic side view a roller skier with roller skis according to the invention
• Figure 2 is a side view in larger scale of a roller ski according to the invention
• Figure 3 shows in a view from above the roller ski according to figure 2.
• figure 1 is shown a side view of a roller skier
• roller skis 2 in accordance with the present invention.
• the binding means 4 are preferably yoke bindings but cable bindings can also be used.
• FIG 2 is shown in bigger scale and in a side view a roller ski 2 according to the invention, and as can be seen here the roller ski comprises a foot plate 6, which is equipped with said binding means 4, and which is carried by a forward and a rear wheel 7, 8, which wheels are preferably pneumatic rubber wheels of much larger size than the rigid, broad wheels at conventional designs of roller skis for crosscountry skiing.
• the supporting members 9 make such a high arc that their upper parts independent of the position of the foot always will be situated above the ski shoe which is held by the binding 4 and on each side of the users' lower leg, whereby they give a safe lateral support for the leg.
• the supporting members 9 run at essentially the same mutual distance between the forward and the rear wheel hubs, the natural movement of the leg when the foot pivots about the toe binding will not be hampered or obstructed.
• the user of the roller ski according to the invention will hereby make the same movement pattern as at real skiing.
• the use is not limited to plane surfaces and wheels which have very little ability of tipping over, but.it is instead possible to manage to counteract and fend off side inclinations of the roller skis. It is hereby possible to use pneumatic wheels 7 , 8 which in turn means that it is possible to run on the roller ski according to the invention also in terrain, on comparatively soft ground etc, which means that the roller skier will have a freedom of chosing the site for his practising track and is spared from running on asphalted roads and the like.
• roller ski according to the invention can preferably be provided with mud guards 10 over the wheels.
