Description

Snørydder Snow plow

Den foreliggende oppfinnelse vedrører en snørydder, og mer spesifikt en snørydder som angitt i ingressen til krav 1. The present invention relates to a snow blower, and more specifically a snow blower as stated in the preamble to claim 1.

Av tidligere kjent teknikk kan nevnes Fl 874371 A, US 5943796 A og US 5570524 A, som beskriver ulike typer snøryddere. Of prior art, mention can be made of Fl 874371 A, US 5943796 A and US 5570524 A, which describe different types of snow blowers.

Den foreliggende oppfinnelse søker å tilveiebringe en mer effektiv snøfjerning, med en snørydder som angitt i karakteristikken til krav 1. The present invention seeks to provide a more efficient snow removal, with a snow blower as stated in the characteristic of claim 1.

Fordelaktige utførelsesformer av oppfinnelsen fremgår av de uselvstendige krav. Advantageous embodiments of the invention appear from the independent claims.

I den etterfølgende beskrivelse, og med henvisning til vedlagte figur 1, er det gitt en nærmere beskrivelse av en fordelaktig, ikke-begrensende utførelsesform av snørydderen i henhold til oppfinnelsen. In the following description, and with reference to the attached Figure 1, a more detailed description of an advantageous, non-limiting embodiment of the snow plow according to the invention is given.

I figur 1 er det vist en snørydder 1 i henhold til oppfinnelsen, innbefattende tre plater 2, 8, 9 i halvstivt materiale der platenes 2, 8, 9 langsider har bølger eller tenner 3 for å skjære sideveis inn i et (ikke vist) snølag. Platene er som vist forbundet med hverandre via hengsler 11 i hver kortende av en midtre plate 8.1 figur 1 er det også vist en bruker av snørydderen 1, og som holder denne oppe i en mulig bruksposisjon. Figure 1 shows a snow plow 1 according to the invention, including three plates 2, 8, 9 in semi-rigid material where the long sides of the plates 2, 8, 9 have waves or teeth 3 to cut laterally into a layer of snow (not shown) . As shown, the plates are connected to each other via hinges 11 at each short end of a middle plate 8.1 Figure 1 also shows a user of the snow blower 1, who holds it up in a possible position for use.

Det er fordelaktig anordnet håndtak 4 på begge langsider av platene 2, 8,9. Videre er det fordelaktig anordnet håndtak 5 på en kortside av den ytre platen 2, og som vist er håndtakene 4, 5 fordelaktig utformet som åpninger eller hull i platene 2, 8, 9. A handle 4 is advantageously arranged on both long sides of the plates 2, 8, 9. Furthermore, a handle 5 is advantageously arranged on a short side of the outer plate 2, and as shown, the handles 4, 5 are advantageously designed as openings or holes in the plates 2, 8, 9.

Ved at håndtak 4, 5 er utformet både på kortsiden og på langsiden av snørydderen kan to personer samarbeide om snøskjæringen ved at en person benytter håndtakene 5 på kortsiden (som vist i figur 1) og den andre personen benytter to av håndtakene 4 på en langside av snørydderen 1. Når snørydderen 1 er saget inn i snølaget kan man fordelaktig løsne den del av snølaget som befinner seg oppå snørydderen ved å stikke en spade ned i dette langs en langside av snørydderen 1. By the fact that handles 4, 5 are designed both on the short side and on the long side of the snowplow, two people can work together on the snow cutting by one person using the handles 5 on the short side (as shown in figure 1) and the other person using two of the handles 4 on a long side of the snowplow 1. When the snowplow 1 has been sawed into the snow layer, the part of the snow layer that is on top of the snowplow can advantageously be loosened by sticking a shovel into it along a long side of the snowplow 1.

Håndtaket 5 på kortsiden er fordelaktig utformet med en forsterkning 6 i en øvre kant av håndtaket 5, idet håndtaket 5 på kortsiden fordelaktig er utformet med feste for et sikringstau 7 og idet festet fordelaktig er anordnet i forsterkningen 6. The handle 5 on the short side is advantageously designed with a reinforcement 6 in an upper edge of the handle 5, the handle 5 on the short side being advantageously designed with an attachment for a safety rope 7 and the attachment being advantageously arranged in the reinforcement 6.

Den midterste platen 8 er fordelaktig noe lenger enn de ytre platene 2, 9, for enkel sammenfolding av snørydderen 1 for lagring eller transport. The middle plate 8 is advantageously somewhat longer than the outer plates 2, 9, for easy folding of the snow blower 1 for storage or transport.

I det minste den ene ytre platen 2 i hvilken håndtak 5 er utformet i en kortside er fordelaktig fleksibel for å kunne overføre sagebevegelse i snølaget fra en vinkelposisjon til en posisjon parallelt med en takflate. At least one outer plate 2 in which handle 5 is designed on a short side is advantageously flexible in order to be able to transfer sawing movement in the snow layer from an angular position to a position parallel to a roof surface.

Platene 2, 8, 9 har fordelaktig glatte siderflater 12, for enkel saging i snølaget og for at en ved saging løsnet del av snølaget kan skli nedover sideflatene 12. The plates 2, 8, 9 advantageously have smooth side surfaces 12, for easy sawing in the snow layer and so that a part of the snow layer loosened by sawing can slide down the side surfaces 12.

En nedre ende av snørydderen 1 motsatt av kortsiden utformet med håndtak 5 er fordelaktig tilveiebrakt med et (ikke vist) påmonterbart, sammenrullbart plastark for forlengelse av en sklibane for den løsnede delen av snølaget, fortrinnsvis utover taket slik at snøen faller ned fra taket etter å ha blitt løsnet. A lower end of the snow plow 1 opposite the short side formed with a handle 5 is advantageously provided with a (not shown) mountable, roll-up plastic sheet for extending a slide for the loosened part of the snow layer, preferably beyond the roof so that the snow falls from the roof after have been loosened.

Selv om det i den viste utførelsesformen er benyttet tre sammenhengslede plater 2, 8, 9 kan et man også tenke seg en snørydder 1 med et annet antall plater, og minimum en enkelt plate 2. Den ene platen av fleksibelt materiale, fordelaktig med en lengde tilsvar-ende som for den viste utførelsesformen, vil da av materialhensyn neppe kunne foldes flatt sammen slik som for den viste, hengslede utførelsesformen, men vil mer sannsynlig kunne rulles sammen til en rull grunnet de samme fleksible materialegenskaper. Although in the embodiment shown three connected plates 2, 8, 9 are used, one can also imagine a snow plow 1 with a different number of plates, and at least a single plate 2. The one plate of flexible material, advantageously with a length correspondingly as for the embodiment shown, due to material considerations it is unlikely to be able to be folded flat as for the hinged embodiment shown, but will more likely be able to be rolled up into a roll due to the same flexible material properties.

I en fordelaktig utførelsesform er den minst ene platen 2 utformet av et egnet plast-materiale, men kan alternativt være utformet av tynnplate eller blikk eller annet egnet fleksibelt materiale med glatt overflate. In an advantageous embodiment, the at least one plate 2 is made of a suitable plastic material, but can alternatively be made of thin plate or tin or other suitable flexible material with a smooth surface.

Den forliggende oppfinnelse skal ikke anses som begrenset til utførelsesformene beskrevet ovenfor, men kan varieres innenfor rammen av de vedlagte krav. The present invention shall not be regarded as limited to the embodiments described above, but may be varied within the framework of the appended claims.
