Description

Uppfinnare: S-E Innernean Foreliggande uppfinning,avser en skidstavstruga, fOretradesvis av det slag som anbringas mellan tvh flansar ph en skidstav. Vid trugor av ,detta slag ha uppstatt vissa problem i samband med trugans vickning i relation till skidstaven. Harvid uppstaende pfikanningar i infastningen ha resulterat i icke onskvarda tojningar sarskilt vid trugans centrum, varigenom infastningen forlorat sin elasticitet och fasthet, och trugans centrumhal vidgats sa att den far benagenhet att lossna ur infastningen. Dessutem ha pakannin,garna pa de trugbanden sammanhallande nitarna blunt sá stora att nitforbindningarna i vissa fall brustit. Inventor: S-E Innernean The present invention relates to a ski pole trough, preferably of the type applied between two flanges or a ski pole. In the case of sledges of this kind, certain problems have arisen in connection with the rocking of the sledge in relation to the ski pole. As a result, pivots in the fastening have resulted in undesirable strains, especially at the center of the trough, whereby the fastening has lost its elasticity and firmness, and the center hall of the trough has been widened so that it has a tendency to detach from the fastening. In addition, the pakannin, the yarns on the trough bands holding the rivets blunt, are so large that in some cases the rivet connections have broken.

Uppfinningen avser att undvika dessa genheter, darigenom att trugan utformas med relativt latt bojliga och vridbara forbindningspartier mellan trugans yttre del och dess centrumparti. Uppfinningen framgar narmare av foljande beskrivning jamte bifogade ritningsfigurer av vilka Fig. 1 visar en schematisk sidovy delvis i sektion av en skidstavstruga. The invention intends to avoid these features, in that the trough is designed with relatively slightly flexible and rotatable connecting portions between the outer part of the trough and its center portion. The invention will become more apparent from the following description taken in conjunction with the accompanying drawing figures, of which Fig. 1 shows a schematic side view partly in section of a ski pole trough.

Fig. 2 och 3 visa skidstavstrugor av tidigaire typ. Figs. 2 and 3 show ski pole troughs of earlier type.

Fig. 4 och 5 visa tva utforingsformer av skidstavstrugor enligt uppfinningen. fig. 1 visas en del av en skidstav 10 med en truga 11 anbragt darpa, varvid trugan rifats i sektion. Trugan ar placered mellan tva flansar 12 och 13 pa staven. Av dessa kan den ena, lampligen den nedre, vara lostagbar for aft mojliggora utbyte av trugan. For att Oka trugans rorlighet kan mellan ena eller hada flansarna och trugen en elastisk bussning va.4 ra anbragt. Figures 4 and 5 show two embodiments of ski pole troughs according to the invention. Fig. 1 shows a part of a ski pole 10 with a trough 11 arranged darpa, the trough being torn into sections. The trough is placed between two flanges 12 and 13 on the rod. Of these, one, probably the lower one, may be detachable for possible replacement of the trough. In order to increase the mobility of the trough, an elastic bushing va.4 ra can be arranged between one or the flanges and the trough.

Fig. 2 visar en truga av konventionell modell. En luans 20 halles av tva korslagda rem-mar av lader eller dylikt 21, 22, vilka lagts om kransen och fasts med nitar 23. Fig. 3 visar en annan truga av konventionell modell. Centrum av trugan bildas liar av ett triangulart parti. 25, vilket medelst nitade oglor 26 fasts vid trugkransne 2. Bhda dessa utforingsformer ha den nackdelen gemensamt, att en vickniag av trugan relativt staven resulterar i en sa kraftig deformation av centrumpartiet, dâ dettas mittdel Mlles mellan flansarna 12 och 13, att deformationen efter nagon tids anvau.dning air staven blir permanent. Trugan her da lag-en styrsel pa staven utan kan fritt vicka mellan olika vinkellagen, vilket icke är onskvart. Man efterstravar att hãlla trugan vinkehatt mot istaven, da. den är 1 obelastat tillstand. Samtidigt shall den au kunna installa sig i vinkel mot staven under inflytande av en yttre kraft. Fig. 2 shows a trough of conventional model. A luans 20 is held by two crossed straps of ladders or the like 21, 22, which are folded over the wreath and fastened with rivets 23. Fig. 3 shows another trough of conventional model. The center of the trough is formed by a triangular portion. 25, which by means of riveted hoops 26 are fixed to the trough ring 2. Both of these embodiments have the disadvantage in common that a wobbling of the trough relative to the rod results in such a strong deformation of the center portion, then its middle part Mlles between the flanges 12 and 13, that the deformation after any time use the air rod becomes permanent. Trugan here then teams a guide on the rod but can freely swing between different angles, which is not uncommon. One strives to hold the trugan waving hat against the ice rod, then. it is 1 unloaded state. At the same time it must be able to position itself at an angle to the rod under the influence of an external force.

For .att undvika de kraftiga deformationer air centrumpartiet som uppst& vid tidigare anvanda trugor foreslas enligt uppfinningen den I fig. 4 eller 5 visade konstruktionen. I fig. 4 Mies trugkransen 20 av en hallare av lader .eller lik.n.ande med fyra armar 31, vilka pa vanligt satt aro lagda runt kransen och nitade till oglor kring denna. Armarna 31 Oro forenade med .smalare pallier 32. Centrum av trugan bildas av ett cirkelringformat mittparti 33, som ar forenat med. partierna 32 medelst radiellt riktade smala partier 34. Nar trugan vickas i forhallande till staven komma de av partierna 34, som ligga nara vickningsaxeln, aft utsattas for vridning. De av partierna 34, som ligga pa avstand Iran vickningsaxeln, komma att utsattas for en bojning tillsammans med angransade parti 32. Centrumpartiet 33 kommer harigenom let bli i huvudsak oph.verkat av trugans rorelse, och da partierna 32 och 34 dro relativt smala hommer den dari uppstaende vridningen .eller b6jningen att resultera .endast i elastiska formforandringar. Par- 2 tierna 34 komma salunda ,artt bilda en form .av kardanupphangning mellan. tva. hallarpartier bildande var sin slirten figur omgivande centrum, en yttre figur bildad .av partierna 32 och 31 och en inre bestaende av partiet 33. In order to avoid the strong deformations in the center portion which arise in the case of previously used troughs, the construction shown in Fig. 4 or 5 is proposed according to the invention. In Fig. 4, the trough wreath 20 is made of a holder of ladders or the like with four arms 31, which are usually placed around the wreath and riveted to eyelets around it. The arms 31 are connected by narrower pallets 32. The center of the trough is formed by a circular ring-shaped central portion 33, which is joined to. the portions 32 by means of radially directed narrow portions 34. When the trough is folded in relation to the rod, those of the portions 34 which lie near the pivot axis are again subjected to rotation. Those of the portions 34, which are at a distance from the pivot axis of Iran, will be subjected to a bend together with adjacent portion 32. The center portion 33 will thereby be mainly affected by the movement of the trough, and since the portions 32 and 34 pulled relatively narrow in the resulting rotation or bend to result only in elastic deformations. The parts 34 come together, thus forming a form of gimbal suspension between. two. hallway portions forming the center surrounding its slippery figure, an outer figure formed by the portions 32 and 31 and an inner consisting of the portion 33.

I fig. har visats en variation av utforingsformen enligt fig. 4. Trugkransen 20 Mlles liar i tre oglor 35 fastade i hornen pa ett i huvudsak triangelformat mellanstycke 36, omfattande relativt Kuala remsor 37 mellan oglorna. Yid mitten av remsorna är mellanstycket medelst korta forbindningspartier 38 fOrenat med ett oirkelringformat mittparti D. Fig. 1 shows a variation of the embodiment according to Fig. 4. The trough ring 20 Mlles liar in three owls 35 fastened in the horns of a substantially triangular intermediate piece 36, comprising relatively Kuala strips 37 between the owls. In the middle of the strips, the intermediate piece is joined by short connecting portions 38 joined by a non-circular center portion D.
