Abstract

The invention relates to a track for a ski slope machine, comprising a multiplicity of element rails (1) arranged transversely to the driving direction of the track and borne by at least one flexible carrying belt, each rail (1) bearing at least one ice pin element? (6) and lateral stabilising element (6). The latter are arranged on wear rails (4) which project from the element rails (1) and are shorter in length than the element rails (1), all the ice pin elements (6) and laterally stabilising elements (6) projecting over the wear rail edges by the same amount. The invention also relates to an element rail (1) in which the ice pin element (6) and laterally stabilising elements (6) are borne by a wear rail (5) which is shorter in length than the element rail (1). <IMAGE>

Description

466 758 ~ 2 10 15 20 25 30 35 gummibärband). För att förbättra fixeringen i gummibärbanden är skenans l undersida lämpligen räfflad, såsom antyds vid 2a i Fig. 3. I sin överdel, dvs. den del som går emot underlaget, är länkskenan 1 försedd med en slitskena 4 av hårt material t.ex. stål, och med samma längd som skenan 1. En ytterligare,-kortare slitskena 5, t.ex. också av stål, (med exempelvis ca 700 mm längd) som skjuter upp, t.ex. ca 10 mm, över slitskenan 4 och vars funktion kommer att beskrivas nedan, är väsent- ligen centralt anordnad på skenan 1 (i huvudsak över mattans driv- hjulsparti) och uppbär sidostabiliserande isdubbar 6. De senare är lämpligtvis fastsvetsade på slitskenan 5 och skjuter upp ett lämpligt stycke över dennas överkant, t.ex. ca 10 mm. Beroende på omständig- heterna är ett lämpligt antal isdubbar ca l till 10. Slitskenorna 4 och S är i det illustrerade fallet fästa i skenan 1 med bultförband 7 genom hål 7a i skenan 2. V Isdubbarna 6 har här formen av ett plattelement med en form som bäst framgår av Fig. 4. Från plattans underdel sträcker sig en central urtagning 8 med en djupare del 8a för slitskenan 5 och grundare del 8b för slitskenan 4. Den sidostabiliserande egenskapen hos isdubben 6 åstadkommes genom att den monteras tvärs skenan 1, dvs. vinkelrätt mot skenans längdaxel, såsom framgår av Fig. 3. Man inser att isdubbarna 6 enkelt kan bytas och flyttas i olika lägen. 466 758 ~ 2 10 15 20 25 30 35 rubber conveyor belt). In order to improve the fixation in the rubber carrier strips, the underside of the rail 1 is suitably grooved, as indicated at 2a in Fig. 3. In its upper part, i.e. the part which goes against the ground, the link rail 1 is provided with a wear rail 4 of hard material e.g. steel, and with the same length as the rail 1. A further, -shorter wear rail 5, e.g. also of steel, (with for example about 700 mm length) which protrudes, e.g. about 10 mm, over the wear rail 4 and whose function will be described below, is substantially centrally arranged on the rail 1 (mainly over the drive wheel portion of the mat) and supports side stabilizing ice studs 6. The latter are suitably welded to the wear rail 5 and project a suitable piece over its upper edge, e.g. about 10 mm. Depending on the circumstances, a suitable number of ice studs is about 1 to 10. In the illustrated case, the wear rails 4 and S are fixed in the rail 1 with bolted joints 7 through holes 7a in the rail 2. The ice studs 6 here have the shape of a plate element with a shape as best seen in Fig. 4. From the lower part of the plate extends a central recess 8 with a deeper part 8a for the wear rail 5 and shallower part 8b for the wear rail 4. The side stabilizing property of the ice stud 6 is achieved by mounting it across the rail 1, i.e. perpendicular to the longitudinal axis of the rail, as shown in Fig. 3. It is realized that the ice studs 6 can be easily replaced and moved in different positions.

En pistmaskinsmatta kan exempelvis innehålla ca 75 länkskenor l. I Fig. 5 visas schematiskt ett exempel på ett pistmaskinsmattarrangemang av isdubbsförsedda länkskenor 1, här av tydlighetsskäl representerade av enbart de båda slitskenorna 4,-5. Lägena för fyra gummibärband 9, i vilka länkskenorna 1 är fästa, är antydda med streckade linjer. De centrala slitskenorna 5 är här alternerande sidoförskjutna något, samtidigt som de tre isdubbarnas 6 inbördes placering också alternerar.A piste machine mat can for instance contain about 75 link rails 1. Fig. 5 schematically shows an example of a piste machine mat arrangement of ice-studded link rails 1, here for reasons of clarity represented by only the two wear rails 4, -5. The positions of four rubber support bands 9, in which the link rails 1 are attached, are indicated by dashed lines. The central wear rails 5 are here alternately laterally offset slightly, at the same time as the mutual position of the three ice studs 6 also alternates.

Eftersom isdubbarna 6 är lika höga på varje skena eller "steg" 1 kan de som ovan nämnts enkelt (då de är svetsbara) flyttas i olika lägen för uppnående av bästa grepp på hårt underlag. Härigenom uppnås även kraf- tigt minskade vibrationer. Greppet på hårt underlag förbättras ytter- ligare av arrangemanget med den uppskjutande slitskenan 5, som uppbär isdubbarna 6. Eftersom pistmaskinens drivhjul ligger an i mattans mittparti (här i ingrepp med de båda centrala gummibärbanden 9), kommer således på ett hårt underlag väsentligen hela maskintyngden att för- delas på de kortare mittskenorna 5, vilket ger ett högre anliggnings- tryck och därmed bättre grepp liksom förbättrade sidoglidnings- och klättringsegenskaper. ' 10 a 466 758 Det har visat sig att man med en pistmaskinsmatta av den ovan be- skrivna typen i förhållande till en konventionell pistmaskinsmatta uppnår åtminstone ca 25% minskade vibrationer, samtidigt som tendensen till besvärande kast så gott som elimineras. Eftersom speciella sido- stabilisatorer inte behöver användas, förenklas och förbilligas även tillverkning och underhåll av pistmaskinsmattan betydligt jämfört med de konventionella pistmaskinsmattorna.Since the ice studs 6 are equally high on each rail or "step" 1, those mentioned above can be easily (when they are weldable) moved in different positions to achieve the best grip on hard surfaces. This also greatly reduces vibration. The grip on a hard surface is further improved by the arrangement with the projecting wear rail 5, which carries the ice studs 6. Since the drive wheel of the piste machine rests in the middle part of the mat (here in engagement with the two central rubber support bands 9), on a hard surface substantially the entire machine weight to be distributed on the shorter center rails 5, which gives a higher abutment pressure and thus better grip as well as improved lateral sliding and climbing properties. It has been found that with a piste machine mat of the type described above in relation to a conventional piste machine mat, at least about 25% reduced vibrations are achieved, while the tendency to troublesome throws is virtually eliminated. Since special side stabilizers do not need to be used, the manufacture and maintenance of the piste mat is also simplified and cheaper compared to the conventional piste mats.

Uppfinningen är givetvis inte begränsad till den ovan beskrivna och i ritningarna visade utföringsformen, utan många modifieringar och ändringar kan utföras utan att man avviker från uppfinningens grund- tanke, sådan den framgår av de följande patentkraven.The invention is of course not limited to the embodiment described above and shown in the drawings, but many modifications and changes can be made without departing from the basic idea of the invention, as it appears from the following claims.
