Description

Skiveblokk. Disc block.

Patentet nr. 87 114 omhandler en wireanordning for trekning av gjenstander, særlig ved running av tømmer i skogen, hvor to eller tre wirer legges over en eller flere faststående wireblokker eller skiver. To av disse wirer løper over en faststående blokkskive og er forsynt i den ene ende med en stopper som hindrer denne ende fra å slippe fri av sin skive og som er forsynt med midler til å koples til vedkom-mende gjenstand som skål trekkes. Patent no. 87 114 deals with a wire device for pulling objects, particularly when running timber in the forest, where two or three wires are laid over one or more fixed wire blocks or disks. Two of these wires run over a fixed block sheave and are provided at one end with a stop which prevents this end from being released from its sheave and which is provided with means to be connected to the relevant object by which the bowl is pulled.

Nærværende oppfinnelse gå ut på en skiveblokk som er særlig egnet til bruk som sådan faststående wireblokk. Den utmerker seg hovedsakelig ved at skiveblokkens ene eller begge sideplater som danner lager for hvert sitt endeparti av skivebolten og ligger på hver sin side av selve skiven, er forsynt med inn mot den motsatte sideplate rettet framspring på en sådan måte at dette eller disse framspring, når begge sideplater er festet i arbeidsstilling udreibart i forhold til hinannen, danner sammen med skiven en smal gjennomgangskanal for wiren og stopper dennes løp over skiven, når en fortykkelse på wiren løper inn mot blokken. The present invention is based on a disc block which is particularly suitable for use as such a fixed wire block. It is distinguished mainly by the fact that one or both side plates of the disc block, which form a bearing for each end part of the disc bolt and lie on each side of the disc itself, are provided with protrusions directed towards the opposite side plate in such a way that this or these protrusions, when both side plates are fixed in a non-rotatable working position in relation to each other, together with the disc forms a narrow passage channel for the wire and stops its run over the disc, when a thickening of the wire runs into the block.

Hensiktsmessig holdes de to sideplater i normal arbeidsstilling udreibart i forhold til hinannen av en låsbar bolt eller liknende som kan være blokkens feste- eller opphengningsorgan..Hver av sideplatene kan ha et fremspring, og disse kan tilsammen begrense gjennomgangskanalen. Hver sideplate kan være forsynt tett ved sitt framspring mécPeri" turige som er bøyet inn mot og griper over kanten av den motsatte sideplate og hensiktsmessig videre rried på den sistnevnte plates ytterside. Derved kan begge sideplater ha identisk form og settes Appropriately, the two side plates in the normal working position are held non-rotatably in relation to each other by a lockable bolt or similar which can be the block's fastening or suspension device..Each of the side plates can have a projection, and these together can limit the passage channel. Each side plate can be provided close at its projection mécPeri" turige which is bent towards and grips over the edge of the opposite side plate and suitably further rried on the outer side of the latter plate. Thereby both side plates can have an identical shape and be set

:ammen i arbeidsstilling med sine fram-ipring vendende mot hinannen og med :ine tunger gripende over ytterkanten av len motsatte sideplate. :ammen in working position with their front-iprings facing each other and with :ine tongues gripping over the outer edge of the opposite side plate.

Oppfinnelsen er vist i en utførelsesform )å tegningen, hvor fig. 1 er et sideriss av ikiveblokken i arbeidsstilling. Fig. 2 viser )lokken sett fra den ene kant. Fig. 3 viser leiene i åpen stilling. The invention is shown in an embodiment in the drawing, where fig. 1 is a side view of the ikive block in working position. Fig. 2 shows the lid seen from one edge. Fig. 3 shows the bearings in the open position.

Selve skiven 1 er dreibar på bolten 2, ivis to ender er lagret i hver sin sideplate I resp. 4. Disse har på de mot hinannen sendende sider framspring 5 resp. 6, gjen-iom hvilke er ført en skruebolt 7 for skive-ilokkens feste- eller opphengningsorgan 8. The disc 1 itself is rotatable on the bolt 2, if two ends are stored in each side plate I or 4. These have protrusions 5 or 6, through which a screw bolt 7 is passed for the disc cover's fastening or suspension means 8.

Ved siden av framspringet er hver side-flate forsynt med en tunge 9 resp. 10 som ;r bøyet over kanten av den annen plate og griper omkring denne kant. Next to the projection, each side surface is provided with a tongue 9 or 10 which is bent over the edge of the second plate and grips around this edge.

Som det sees ligger framspringene så iær selve skiven for wiren 11 at der mellom skiven og framspringet bare er en trang jjennomgangskanal 12 for wiren, når sideplatene holdes i arbeidsstilling av skruen 7. As can be seen, the protrusions are so close to the disc itself for the wire 11 that there is only a narrow passage channel 12 for the wire between the disc and the protrusion, when the side plates are held in working position by the screw 7.

Wiren 11 har i den ene ende en for-;ykkelse eller stopper 13 som ikke kan løpe gjennom kanalen 12, når delene er i ar-Deidsstilling (fig. 1 og 2). Hvis derimot skruen 7 tas ut, kan skivene 3 og 4 dreies forhold til hinannen til den i fig. 3 viste stilling, hvori wiren lett kan legges over skiven 1, hvoretter platen 3 dreies tilbake Dg skruen 7 settes inn. The wire 11 has at one end an extension or stop 13 which cannot run through the channel 12, when the parts are in the closed position (fig. 1 and 2). If, on the other hand, the screw 7 is taken out, the discs 3 and 4 can be turned relative to each other to the one in fig. 3 shown position, in which the wire can easily be laid over the disk 1, after which the plate 3 is turned back Dg the screw 7 is inserted.

Som det sees er de to plater 3 og 4 As can be seen, the two plates are 3 and 4

identiske. identical.

Det er klart at det er tilstrekkelig å forsyne bare den ene av sideplatene med et' framspring som da får den dobbelte tyk-kelse. It is clear that it is sufficient to provide only one of the side plates with a projection, which then gets twice the thickness.

Claims
