Definitions
- the present invention relates to a roller ski including a ski body mounted on a forward and a rear wheel, a binding or attachment for a ski shoe (boot) being arranged between the wheels, close to the rear wheel.
- ski-skating In skiing today, apart from the conventional poling and diagonal skiing, there is used to an ever-increasing extent so-called “ski-skating". This is pronounced to a high degree of ordinary ice skating, and is either done by toeing out with the ski tips, so-called “herringboning”, this technique mostly being used heretofore on upward slopes, or by toeing out with one ski only, resulting in that the other ski (hereinafter designated the “track ski”) is kept in the track, the other ski (hereinafter designated “the skate ski”) being toed out sideways, this manner of skiing being the one most prevalent of the two, and allowing the maintenance of greater speed with less effort than customary poling or diagonal skiing. This kind of skiing is most often done without so-called ground wax which also contributes to the ski working more lightly and quickly.
- the track ski In snow skiing using single-sided toeing out of one ski, the track ski is down in the track or rut formed by earlier skiing and the transverse forces acting on the ski and urging it outtransversely are entirely taken up by the edges of the rut.
- the track ski In a corresponding manner of skiing with roller skis, the track ski is also affected by transverse forces steering it outwards, and it must be returned to the travelling direction using a technique not found in the present snow skiing technique.
- the foot on the skate ski is put down as near as possible to the heel on the track ski, the skate ski then crossing over the track ski, which is possible since the track ski is down in the rut at a depth which is greater than the height of the ski.
- skate ski base In skiing with snow skis, customary in the technique in question, the skate ski base is angled to a considerable degree. If known roller skis are angled to the same amount, the roller fork mountings scrape against the ground, which means that the skier cannot train technically correctly and also that the fork mounting can dig into the ground and cause abrupt stoppage with a fall and a risk of injury.
- roller ski It is attempted today, by such as the selection of materials, to make the roller skis in question as light as possible.
- a roller ski is described in DE-A-28 23 152.
- the roller ski comprises a ski body mounted on forward and rear wheels and it includes two parallel bars of solid cylindrical cross sections being connected with cross brac- ings and carrying a binding for the ski shoe close to the rear wheels.
- the known roller ski is a rather stiff construction for taking up vertical and horizontal forces.
- roller skis of today are dimensioned to completely take up both vertical and horizontal forces so that, for example, the positions of the wheels in the travelling direction will not be changed. They are often also implemented with a roll-back stop unnecessary for "ski skating” involving that wheel hub and shaft are made in strong steel. Altogether this makes the roller ski used at present about 3 times as heavy as the appropriate competition snow ski of today.
- the object of the present invention is therefore to solve the above-mentioned problem in the difference between skiing with snow skis and skiing with roller skis, and particularly with reference to ski skating.
- roller ski defined in claim 1.
- the ski body By shaping the hollow section with a rectangular cross section with its short side downwards, the ski body will be laterally flexible for the skiing load. At the same time it supports mounting portions for the forward and rear wheels.
- the carrying member is implemented such as to take up vertical forces to a greater extent than horizontal forces, it is suitable to use for it a rectangular hollow section with its short side downwards.
- the inventive roller ski has been formed with only a half fork mounting for each of the forward and rear wheels.
- the fork mountings of the roller ski are formed by the hollow section itself.
- the lightness of the ski is enabled by using less material, since it does not need to be dimensioned for being straight when it takes up horizontal forces, and is intended to be laterally flexible, as well as not being provided in a basic embodiment with a roll-back stop not necessary for skate skiing.
- the wheel hub can then be made in such as aluminium or plastics material.
- the wheel shaft can be implemented in lighter material, e.g. with a steel core for carrying and assembly.
- FIGS 1 and 2 illustrate one-sided toeing-out on snow with ordinary skis, one ski, the track ski 1, following the track or rut 2 in the snow. The other ski, the skate ski 3, is put down behind the skier in ski-skating so that it crosses over the other ski, as will be seen from Figure 1.
- Figure 8 it will be seen how this crossing of the skis 1 and 3 is possible when skiing on snow, due to the track ski 1 lying deep in the rut 2.
- roller skis implemented in accordance with the present invention, there is however obtained an action entirely corresponding to that carried out in the relevant snow skiing technique.
- the roller ski in accordance with the present invention as will be more closely described in conjunction with Figures 10-13, is short and it has the binding or foot deck arranged in the immediate vicinity of the rear wheel.
- the roller skier can thus train and ski in exactly the same way as is applicable to skiing on snow, as will be noted by comparing Figures 5 and 7 with Figures 1 and 2. It will thus be seen from Figure 5 that the skate ski 3 can be moved crosswise behind the track ski 1, the travelling movement and the application of effort corresponding to what is applicable with the crossing ski movement according to Figure 1. This is also apparent from the comparison of Figure 9 with Figure 8.
- the reason that the track ski 1 during skiing on roller skis in accordance with the present invention follows the direction of travel 2' without the skier needing to take any corrective movements is primarily due to the lateral flexibility of the ski, as is exaggeratedly indicated in Figure 6.
- the roller skis in accordance with the invention are namely formed to be laterally flexible. Another reason for the tracking property may be attributed to the journalling of the wheel and the implementation of the wheel.

Abstract
Description
- The present invention relates to a roller ski including a ski body mounted on a forward and a rear wheel, a binding or attachment for a ski shoe (boot) being arranged between the wheels, close to the rear wheel.
- In skiing today, apart from the conventional poling and diagonal skiing, there is used to an ever-increasing extent so-called "ski-skating". This is reminiscent to a high degree of ordinary ice skating, and is either done by toeing out with the ski tips, so-called "herringboning", this technique mostly being used heretofore on upward slopes, or by toeing out with one ski only, resulting in that the other ski (hereinafter designated the "track ski") is kept in the track, the other ski (hereinafter designated "the skate ski") being toed out sideways, this manner of skiing being the one most prevalent of the two, and allowing the maintenance of greater speed with less effort than customary poling or diagonal skiing. This kind of skiing is most often done without so-called ground wax which also contributes to the ski working more lightly and quickly.
- In snow skiing using single-sided toeing out of one ski, the track ski is down in the track or rut formed by earlier skiing and the transverse forces acting on the ski and urging it outtransversely are entirely taken up by the edges of the rut.
- In a corresponding manner of skiing with roller skis, the track ski is also affected by transverse forces steering it outwards, and it must be returned to the travelling direction using a technique not found in the present snow skiing technique.
- In snow skiing with toeing out of one ski, the foot on the skate ski is put down as near as possible to the heel on the track ski, the skate ski then crossing over the track ski, which is possible since the track ski is down in the rut at a depth which is greater than the height of the ski.
- With roller skis this crossover is impossible, and the difference between snow skiing will be greater the more the track ski is extended behind the shoe heel and the wider the skate ski is, due, for example, to the fact that the fork halves of the roller mountings on both sides of the roller must be added to the width of the roller.
- In skiing with snow skis, customary in the technique in question, the skate ski base is angled to a considerable degree. If known roller skis are angled to the same amount, the roller fork mountings scrape against the ground, which means that the skier cannot train technically correctly and also that the fork mounting can dig into the ground and cause abrupt stoppage with a fall and a risk of injury.
- It is attempted today, by such as the selection of materials, to make the roller skis in question as light as possible. Such a roller ski is described in DE-A-28 23 152. The roller ski comprises a ski body mounted on forward and rear wheels and it includes two parallel bars of solid cylindrical cross sections being connected with cross brac- ings and carrying a binding for the ski shoe close to the rear wheels. The known roller ski is a rather stiff construction for taking up vertical and horizontal forces.
- Also other roller skis of today are dimensioned to completely take up both vertical and horizontal forces so that, for example, the positions of the wheels in the travelling direction will not be changed. They are often also implemented with a roll-back stop unnecessary for "ski skating" involving that wheel hub and shaft are made in strong steel. Altogether this makes the roller ski used at present about 3 times as heavy as the appropriate competition snow ski of today.
- The object of the present invention is therefore to solve the above-mentioned problem in the difference between skiing with snow skis and skiing with roller skis, and particularly with reference to ski skating.
- This is achieved by the roller ski defined in claim 1.
- By shaping the hollow section with a rectangular cross section with its short side downwards, the ski body will be laterally flexible for the skiing load. At the same time it supports mounting portions for the forward and rear wheels.
- That the track ski in roller skiing tends to diverge is thus prevented by the carrying member being so slender in relation to horizontal forces that it flexes, the wheels then changing their attitude in relation to the straight line so that the roller ski steers inwards towards the direction from which the horizontal force comes. When the roller ski is not actuated on by horizontal forces it remains straight, of course, and goes straight forward like other known roller skis.
- Since the carrying member is implemented such as to take up vertical forces to a greater extent than horizontal forces, it is suitable to use for it a rectangular hollow section with its short side downwards.
- To prevent that the foot deck will not reinforce the carrying member and prevent its lateral deflection properties it is suitable to make cutouts in the areas of the deck not required for its intended purpose, thus solely forming a toe portion and a heel portion.
- So that the skate ski may have its base tilted at a large angle to the horizontal and to enable it to be put down as near the shoe on the track ski as possible, the inventive roller ski has been formed with only a half fork mounting for each of the forward and rear wheels. In accordance with the invention the fork mountings of the roller ski are formed by the hollow section itself.
- The lightness of the ski is enabled by using less material, since it does not need to be dimensioned for being straight when it takes up horizontal forces, and is intended to be laterally flexible, as well as not being provided in a basic embodiment with a roll-back stop not necessary for skate skiing. The wheel hub can then be made in such as aluminium or plastics material. The wheel shaft can be implemented in lighter material, e.g. with a steel core for carrying and assembly.
- The present invention will now be described in detail below in connection with the preferred embodiments illustrated on the accompanying drawings, where
- Figures 1 and 2 illustrate known skiing technique using ordinary skis on snow,
- Figures 3 and 4 illustrate the same skiing technique using known roller skis,
- Figures 5-7 again show the same skiing technique, but now using roller skis in accordance with the present invention,
- Figures 8 and 9 illustrate in more detail what is characteristic for this skiing technique, on snow with ordinary skis and also on the ground using roller skis,
- Figure 10 is a side view of a first embodiment of the inventive roller ski,
- Figures 11 and 12 illustrate the roller ski according to Figure 10 seen from above,
- Figure 13 illustrates a second embodiment of the inventive roller ski seen from above,
- Figures 14-16 are sections A, B and C according to Figures 10 and 13,
- Figure 17 is a detail of a preferred embodiment of the journalling shaft for the roller ski in accordance with the invention and
- Figure 18 is a preferred embodiment of a wheel for the inventive roller ski.
- When skiing on snow the skiers have more and more embraced a skiing style similar to ordinary ice-skating. This can be executed as one-sided toeing-out of the ski tip or toeing-out both skis. Figures 1 and 2 illustrate one-sided toeing-out on snow with ordinary skis, one ski, the track ski 1, following the track or rut 2 in the snow. The other ski, the
skate ski 3, is put down behind the skier in ski-skating so that it crosses over the other ski, as will be seen from Figure 1. In Figure 8 it will be seen how this crossing of theskis 1 and 3 is possible when skiing on snow, due to the track ski 1 lying deep in the rut 2. - If this skiing style is transferred to roller skis of the kind known up to now, the situation illustrated in Figures 3 and 4 is obtained. Since known roller skis are relatively long, i.e. the binding is arranged at a good distance from the rear wheels, the
skate ski 3 cannot be made to cross the "track" of the track ski 1, which is illustrated in Figure 3. Furthermore, known roller skis are so implemented that if the ski skating technique is used, the track ski 1 diverges from the track and forms an angle a to the travelling direction 2' in a manner illlustrated in Figure 4, and must be returned to the track by the skier. This return movement or force has no correspondence in the relevant snow skiing technique. - With roller skis implemented in accordance with the present invention, there is however obtained an action entirely corresponding to that carried out in the relevant snow skiing technique. The roller ski in accordance with the present invention, as will be more closely described in conjunction with Figures 10-13, is short and it has the binding or foot deck arranged in the immediate vicinity of the rear wheel. The roller skier can thus train and ski in exactly the same way as is applicable to skiing on snow, as will be noted by comparing Figures 5 and 7 with Figures 1 and 2. It will thus be seen from Figure 5 that the
skate ski 3 can be moved crosswise behind the track ski 1, the travelling movement and the application of effort corresponding to what is applicable with the crossing ski movement according to Figure 1. This is also apparent from the comparison of Figure 9 with Figure 8. - The reason that the track ski 1 during skiing on roller skis in accordance with the present invention follows the direction of travel 2' without the skier needing to take any corrective movements is primarily due to the lateral flexibility of the ski, as is exaggeratedly indicated in Figure 6. The roller skis in accordance with the invention are namely formed to be laterally flexible. Another reason for the tracking property may be attributed to the journalling of the wheel and the implementation of the wheel.
- In Figures 10-12, 14 and 15 there is illustrated a first embodiment of the roller ski in accordance with the present invention. The roller ski includes a
ski body 10 mounted on aforward wheel 11 and arear wheel 12. Theski body 10 comprises a hollow body with a rectangular cross section with its short side downwards, as will be seen from Figure 14. The hollow body thus hasside walls 13 of greater extension than its upper andbottom walls ski body 10 is obtained when skiing. - In this embodiment of the roller ski in accordance with the invention, the
upper wall 14 of the hollow body is formed with afoot deck foot deck longitudinal axis 20 of theski body 10, and hasfastenings 18 for bindings for the ski shoe (not shown). Thefoot deck rear wheel 12 and is further divided into atoe portion 16 and aheel portion 17, substantially for reducing the weight of the roller ski, but also so as not to constitute an obstacle to the above-mentioned lateral flexing ability. - The
wheels sided fork 19 being formed by the hollow body. In the embodiment illustrated in Figures 10-12 of the roller ski, the hollow body is joggled so that theforks 19 are parallel to the rest of the hollow body. The central axis of the wheels, which is at right angles to their axes of rotation, is thus in register with thelongitudinal axis 20 of theski body 10. - A second embodiment of the roller ski in accordance with the present invention is illustrated in Figures 13, 14 and 16. Elements which are the same as in the above-described first embodiment have been given the same reference numerals. The illustrated second embodiment of the roller ski in accordance with the invention has a foot deck 16', 17' starting from the
upper wall 14 of the hollow body in only one direction as will be seen from Figure 16. The foot deck 16', 17', which is similarly divided into a toe portion 16' and a heel portion 17', thus has its longitudinal axis displaced parallel relative the longitudinal axis of the ski body in a direction towards the roller ski lying at its side in a roller ski pair. - With this arrangement of the foot deck 16', 17', the
wheels straight ski body 10, 19'. - Returning to Figure 12, it will be seen that this figure illustrates to an exaggerated scale how the track ski 1 (Fig. 6) flexes laterally under the action of the horizontal forces P occurring during skiing, thus causing the track ski to go straight.
- An essential part of the invention for this maintenance of tracking would also be the suspension of the
wheels extensions 19, 19' of the hollow body, these extensions having been termed fork mountings hereinbefore. Figure 17 illustrates thewheel shaft 21 made in a light material such as plastics or aluminium with acore 22, e.g. of steel. Thecore 22 has the form of a screw or bolt which consists of, or reinforces the carrying properties of thewheel shaft 21 as well as fastening it to theski body 10. Through holes 33 have thus been made in the hollow section (the forks)side walls 13. The screw or bolt-like core 22 is taken through theholes 23 and into thehollow wheel shaft 21, which has aninterior thread 24 coacting with athread 25 on thecore 22. The portion of thewheel shaft 21 facing towards oneside wall 13 of theski body 10 has aflange 26 of large diameter, forming a contact surface against theside wall 13 when thecore 22 is threaded into thewheel shaft 21. - The
wheel shaft 21 is intended to coact with awheel wheel rim 27, as will be seen from Figure 12. Therim 27 may be of plastics and form a relatively largeinner cavity 28 in thewheel rim 27 carries a tire or atread 29 of suitable form and pattern for roller skis. Therim 27 is formed to carry ball orroller bearings 30 at the sides of thewheel bearings 30 are mounted on thewheel shaft 21 and thewheel wheel shaft 21 with a spring clip (not shown) in theannular groove 31 at the end of thewheel shaft 21.
