Abstract

The mast (6) and horizontal beam (7) are telescopically length adjustable and can be fixed in an extended position. The tips (9, 12) of the mast and beam have sharp points housed inside a sleeve, eyelet etc. at two of the sail corners (3, 5), the other two corners (2, 4) being releasably attached to the opposite end of the mast and beam. With the mast and beam fully retracted and the sail tied around them and held in place with e.g. a band, the dismantled sail construction can be used as an ice pick, preferably with a handle.

Description

511 685 2 spets 9 försedd ände, som är förd genom en öljett 10 fastsatt vid seglets hörnparti 3. 511 685 2 end 9, which is passed through an eyelet 10 attached to the corner portion 3 of the sail.

Bcnnen 7 är på motsvarande sätt försedd med en grövre del 7a och en teleskopiskt utskjutbar del 7b låsbar medelst en låsring 7c. Bonnens 7 grövre del 7a har en ände 7d, som är inskjuten i en ficka ll fastsydd vid seglets hörnparti 4, och bonnens utskjutbara del 7b har en med en vass spets 12 försedd ände, som är förd genom en öljett 13 fastsatt vid seglets hörnparti 32 Monteringen av seglet sker genom att seglet l vecklas ut och mastens 6 och bommens 7 ändar förs in i tillhörande fickor 8,11 och öljetter 10,13 under utskjutning av de utskjutbara delarna 6b och 7b tills seglet är ordentligt spänt, då låsringarna 6c och 7c drages åt för fixering av de teleskopiskt utskjutbara delarna. Därefter anbringas lämpligen en fästanordning 14 i form av exempelvis ett kardborrband runt mastens och bommens korsningspartier för fixering av dessa inbördes. Alternativt kan ett fast förband användas i form av ett beslag, som är glídbart fästat på masten och trnmen och omsluter dessa, och som medger vridning av masten och bommen från korsande läge till ett läge parallellt bredvid varandra och omvänt (ej visat).The body 7 is correspondingly provided with a coarser part 7a and a telescopically extendable part 7b lockable by means of a locking ring 7c. The coarser part 7a of the well 7 has an end 7d which is inserted into a pocket 11 sewn to the corner portion 4 of the sail, and the extendable part 7b of the well has a end provided with a sharp tip 12, which is passed through an eyelet 13 attached to the corner portion 32 of the sail The sail is mounted by unfolding the sail 1 and inserting the ends of the mast 6 and the boom 7 into the associated pockets 8,11 and eyelets 10,13 while firing the extendable parts 6b and 7b until the sail is properly tensioned, when the locking rings 6c and 7c tightened to fix the telescopically extendable parts. Thereafter, a fastening device 14 in the form of, for example, a Velcro strap is suitably applied around the crossing portions of the mast and the boom for fixing them mutually. Alternatively, a fixed joint may be used in the form of a bracket which is slidably attached to the mast and the frame and encloses them, and which allows rotation of the mast and boom from a crossing position to a position parallel next to each other and vice versa (not shown).

Vid demontering av skridskoseglet lossas låsringarna 6c och 7c och masten och bonnen skjuts ihop till kortaste längd, varvid seglet lösgörs från dessa. Masten och bonmen placeras sedan parallellt med varandra med de vassa spetsarna belägna bredvid varandra. Motsatta ändar är lämpligen försedda med handtag 15 med handledsrem av liknande slag som användes vid skidstavar och ispikar. Därefter viras seglet hårt omkring masten och txnnæn, och fixeras seglet medelst ett band e.d., lämpligen ett kardborrband 16, såaun visas i fig.2. Det demonterade skridskoseglet utgör därmed en enhet, som kan användas son en ispik med två vassa spetsar eller som ett räddningredskap i händelse av att isen skulle brista.When disassembling the skate sail, the locking rings 6c and 7c are loosened and the mast and beam are pushed together to the shortest length, whereby the sail is detached from them. The mast and beam are then placed parallel to each other with the sharp tips located next to each other. Opposite ends are suitably provided with handles 15 with wrist straps of a similar type used for ski poles and ice spikes. Then the sail is wound tightly around the mast and txnnæn, and the sail is fixed by means of a band or the like, preferably a Velcro strap 16, as shown in fig.2. The disassembled skate sail thus forms a unit, which can be used as an ice nail with two sharp points or as a rescue tool in the event that the ice should break.

Uppfinningen är självfallet inte begränsad till den här beskrivna och visade utföringsformen utan kan modifieras på åtskilliga sätt inom ramen för den i patentkraven definierade uppfinningen. Sålunda kan exempelvis bunnen ha mindre diameter än masten och vid demontering av skridskoseglet placeras inuti masten. Vidare kan naturligtvis seglet vid demonteringen viras omkring masten eller bonnen och fästas på denna, varefter masten och bommen kan användas som två spetsförsedda stavar.The invention is of course not limited to the embodiment described and shown here, but can be modified in several ways within the scope of the invention defined in the claims. Thus, for example, the bottom can have a smaller diameter than the mast and when dismantling the skate sail is placed inside the mast. Furthermore, of course, during disassembly, the sail can be wrapped around the mast or beam and attached to it, after which the mast and boom can be used as two pointed rods.

Claims
