Description

Anordning for drift av hengestillas. Device for operating suspended scaffolding.

Foreliggende oppfinnelse vedrører en anordning for drift av hengestillas og vedrører spesielt den type anordninger som de-fineres i det etterfølgende patentkravs innledning og som utgjør gjenstanden for patentbeskyttelsen ifølge svensk patent nr. 309484. The present invention relates to a device for operating suspended scaffolding and relates in particular to the type of device which is defined in the introduction of the following patent claim and which forms the subject of patent protection according to Swedish patent no. 309484.

Fra den tidligere kjente anordning er det gitt anvisning på å la linen samvirke med drivskiven og motskiven slik at ...linen dan-ner en åttetall-formig slynge. From the previously known device, instructions have been given to allow the line to interact with the drive sheave and counter sheave so that ... the line forms a figure-eight-shaped loop.

Den foreliggende oppfinnelse tar sikte på å fremskaffe en mulighet til å tre linen på en annen måte slik at det oppnås den fordel at motskiven kan gjøres smalere, det vil si har. færre spor, enn drivskiven, samtidig som ileggingen av løftelinen blir enklere. Det som først og fremst kjennetegner, en anordning ifølge den foreliggende oppfinnelse er angitt i det medfølgende patentkravs kjennetegnende del. The present invention aims to provide an opportunity to thread the line in a different way so that the advantage is achieved that the counter sheave can be made narrower, that is to say has. fewer tracks than the drive sheave, while at the same time the insertion of the lifting line becomes easier. What primarily characterizes a device according to the present invention is indicated in the characteristic part of the accompanying patent claim.

I det etterfølgende skal det nærmere beskrives en passende utførelsesform som er utstyrt med de spesielle kjennetegn ifølge den foreliggende oppfinnelse, under henvisning til medfølgende tegninger, hvori: Fig. 1 viser anordningen for drift av hengestillaset, In what follows, a suitable embodiment which is equipped with the special characteristics according to the present invention will be described in more detail, with reference to accompanying drawings, in which: Fig. 1 shows the device for operating the suspended scaffold,

vist 'i perspektivriss. shown 'in perspective view.

Fig. 2 viser hvorledes linens slynger er anordnet. Fig. 2 shows how the line's loops are arranged.

I fig. 1 er det følgelig vist den anordning som er innrettet til å drive et hengestillas eller liknende og anordningen for-utsettes fast forbundet med hengestillaset på i og for seg kjent måte. Anordningen er utstyrt med en beskyttelseskappe A utstyrt med et antall låsekroker. Et fjærende organ B bestående av en strekkfjær og låsemutter samvirker med en arm C som bærer en trykkrull H. Armen C er dreibart forbundet med et stativ eller hengestillaset ved hjelp av en tapp H<1.>En låsebøyle D er innrettet til å samvirke med linen L og består av en stang som samvirker med or-ganet G. In fig. 1 shows the device which is designed to drive a suspended scaffold or the like, and the device is assumed to be firmly connected to the suspended scaffold in a manner known per se. The device is equipped with a protective cover A equipped with a number of locking hooks. A resilient member B consisting of a tension spring and locking nut co-operates with an arm C carrying a pressure roller H. The arm C is pivotally connected to a stand or suspension scaffold by means of a pin H<1.>A locking hoop D is arranged to co-operate with the line L and consists of a rod that cooperates with the organ G.

En tannh julsveksel E samvirker med en drivskive F og i samme plan som drivskiven finnes en motskive I. Drivskiven har to spor mens motskiven bare har et spor. Den utadløpende linepart L' er tredd gjennom en linestyring G. A gear wheel E cooperates with a drive disc F and in the same plane as the drive disc there is a counter disc I. The drive disc has two grooves while the counter disc has only one groove. The outgoing line part L' is threaded through a line guide G.

Under henvisning til fig. 2 skal det beskrives nærmere«. ileggingen av linen L. Først legges linen L rundt drivskiven F og nærmere betegnet i dennes innerspor. Deretter legges linen rundt motskiven I samt tilbake til drivskiven og nå i dennes ytterspor. With reference to fig. 2 it must be described in more detail'. the laying of the line L. First, the line L is laid around the drive sheave F and more specifically in its inner groove. The line is then laid around the counter sheave I and back to the drive sheave and now in its outer groove.

I denne stilling skal beskyttelseskappen A stenges og deretter på-settes trykkrullen H ved å.dreie'armen C slik at låsebøylen D kan hakes fast. Muen vil derved komme til å løpe gjennom låsebøylen. In this position, the protective cover A must be closed and then the pressure roller H must be attached by turning the arm C so that the locking bracket D can be engaged. The muen will thereby run through the locking hoop.

I denne stilling er beskyttelseskappen låst i stengt stilling og kan ikke åpnes så lenge linen er. strukket. Linen, skal ilegges i line-styringen G og den utgående linepart L<*>kan utstyres med en avtag-bar vekt for å holde linen strukket. In this position, the protective cover is locked in the closed position and cannot be opened as long as the line is. stretched. The line must be inserted into the line guide G and the outgoing line part L<*>can be equipped with a removable weight to keep the line taut.

For å gi en mer detaljert beskrivelse av anordningens prin-sipielle oppbygning, henvises til beskrivelsen for det svenske patentskrift nr. 309-484. To give a more detailed description of the device's principle structure, reference is made to the description for the Swedish patent document no. 309-484.

Oppfinnelsen er ikke begrenset til det som er beskrevet ovenfor og som angitt i utførelseseksemplet, men det kan foretas modifikasjoner innenfor rammen av det etterfølgende patentkrav. The invention is not limited to what is described above and as indicated in the embodiment, but modifications can be made within the scope of the subsequent patent claim.
