Description
Forlengbar stige med sidestykker av profilerte rør. Extendable ladder with side pieces of profiled pipes.
Den foreliggende oppfinnelse går ut på en forlengbar stige med sidestykker av profilerte rør, hensiktsmessig av lettmetall, hvor rørtverrsnittet er hovedsakelig rektangulært med sin lengste dimensjon loddrett mot stigens plan, og hvor der i planet foran stigetrinnene på innsiden av sidestykket, finnes et langsgående spor, hvis bunn ligger innenfor det rektangulære rør-tverrsnitt. The present invention is based on an extendable ladder with side pieces of profiled pipes, preferably of light metal, where the pipe cross-section is mainly rectangular with its longest dimension perpendicular to the plane of the ladder, and where there is a longitudinal groove in the plane in front of the ladder steps on the inside of the side piece, whose bottom lies within the rectangular tube cross-section.
Oppfinnelsen har til hensikt å skaffe The invention aims to provide
en slik konstruksjon av stigen at en stigedel kan skyves direkte inn i en underliggende stigedel med noe større bredde uten hjelp av styretrinser, utstikkende bøyler such a construction of the ladder that a ladder part can be pushed directly into an underlying ladder part with a slightly larger width without the aid of guide pulleys, protruding hoops
eller andre bæreorganer montert på stigens sidestykker. Dette oppnås ifølge oppfinnelsen hovedsakelig ved at der på sidestykkets utadvendte side forekommer et parti som rager ut utenfor rørtverrsnittet og som er bestemt til å løpe i det førstnevnte spor på den underliggende stigedel og utgjøres av en langs sidestykket løpende skinne, or other supporting means mounted on the ladder's side pieces. According to the invention, this is mainly achieved by the fact that on the outward facing side of the side piece there is a part which protrudes beyond the pipe cross-section and which is intended to run in the first-mentioned groove on the underlying ladder part and is made up of a rail running along the side piece,
samt at det spor som ligger på innsiden av sidestykket oventil begrenses av en i rør-tverrsnittet utformet list, samtidig som der på sidestykkets ytterside er anordnet et spor med tilsvarende dimensjoner til å oppta listen på den underliggende stigedel. and that the track on the inside of the side piece above is limited by a strip designed in the pipe cross-section, at the same time that a track with corresponding dimensions is arranged on the outside of the side piece to accommodate the strip on the underlying ladder part.
På tegningen er vist et utførelsesek-sempel på en stige i henhold til oppfinnelsen. Fig. 1 viser skjematisk en forlengbar stige i tverrsnitt. Fig. 2 viser skjematisk stigen i uttruk-ket stilling. Fig. 3 viser tverrsnitt av stigens ene sidestykke i større målestokk. The drawing shows an embodiment of a ladder according to the invention. Fig. 1 schematically shows an extendable ladder in cross section. Fig. 2 schematically shows the ladder in an extended position. Fig. 3 shows a cross section of one of the ladders counterpart on a larger scale.
, I henhold til fig. 1 og 2 er stigen utført med tre stigedeler A, B, C, hvorav den siste utgjør den øverste stigedel og;har den min-ste bredde. Sidestykkene er betegnet 1, 2 og , according to fig. 1 and 2, the ladder is made with three ladder parts A, B, C, the last of which constitutes the top ladder part and has the smallest width. The side pieces are designated 1, 2 and
og 3 og stigetrinnene 4. and 3 and the ladder steps 4.
Som det fremgår tydeligere av fig. 3, As can be seen more clearly from fig. 3,
er sidestykkene utført av profilert rør, hensiktsmessig av lettmetall, med et rørtverr-snitt som er hovedsakelig rektangulært. the side pieces are made of profiled pipe, preferably of light metal, with a pipe cross-section that is mainly rectangular.
Tverrsnittets lengste dimensjon utgjør The longest dimension of the cross-section constitutes
høyden av sidestykket loddrett på stige-trinnenes plan. Stigetrinnet er ført inn i den midterste del av rørtverrsnittet og fast forbundet med dette. I planet ovenfor stigetrinnene har sidestykket på innsiden et the height of the side piece vertically on the plane of the ladder steps. The ladder rung is inserted into the middle part of the pipe cross-section and firmly connected to this. In the plane above the steps, the side piece on the inside has a
langsgående spor 5, som ifølge eksemplet har rektangulært tverrsnitt med bunnpar-tiet 6 anordnet parallelt med sidestykkets innervegg 7 og sideveggene 8 og 9 vinkel-rett til denne. Bunnen 6 ligger innenfor det rektangulære rørtverrsnitts omriss. På yttersiden av sidestykket finnes der ne-dentil et utspringende parti 10 i form av en skinne som løper langsetter sidestykket. longitudinal track 5, which according to the example has a rectangular cross-section with the bottom part 6 arranged parallel to the inner wall 7 of the side piece and the side walls 8 and 9 perpendicular to this. The bottom 6 lies within the outline of the rectangular pipe cross-section. On the outer side of the side piece there is a projecting part 10 in the form of a rail which runs along the length of the side piece.
Denne skinne på en stigedel skal løpe i This rail on a ladder section must run in
sporet 5 i den underliggende stigedel, som det fremgår av fig. 1. the groove 5 in the underlying ladder part, as can be seen from fig. 1.
Sporet 5 på innsiden av sidestykket begrenses oventil av en list 11, som er utformet i rørtverrsnittet, og dannes av spor-veggen 9, en del av rørtverrsnittets øvre vegg 12 og et veggparti 13, som kan ligge i samme plan som sideveggen 7 som vist på fig. 3. Alt etter den ønskede form av rør-tverrsnittet kan imidlertid veggen 13 be-finne seg innenfor eller utenfor den rektangulære kontur. Under hensyntagen til dimensjonene på listen 11 anordnes der på yttersiden av sidestykket et spor 14 i til-slutning til skinnen 10, slik at denne og sporet 14 på en stigedel samvirker med henholdsvis sporet 5 og listen 11 på en underliggende stigedel. Av det foregående turde det fremgå at sporet 14 på yttersiden av stigestykket er unødvendig i tilfelle av at listen 11 har liten høyde i stigens bred-deretning. The groove 5 on the inside of the side piece is limited at the top by a strip 11, which is designed in the pipe cross section, and is formed by the groove wall 9, part of the pipe cross section upper wall 12 and a wall section 13, which can lie in the same plane as the side wall 7 as shown on fig. 3. However, depending on the desired shape of the pipe cross-section, the wall 13 can be inside or outside the rectangular contour. Taking into account the dimensions of the strip 11, a groove 14 is arranged on the outer side of the side piece in connection with the rail 10, so that this and the groove 14 on a ladder part cooperate with respectively the groove 5 and the strip 11 on an underlying ladder part. From the foregoing, it should appear that the groove 14 on the outside of the ladder piece is unnecessary in the event that the strip 11 has a small height in the width direction of the ladder.
Såvel sporet 5 som skinnen 10 kan på et sted på sidestykket være kledd med en skoning 15 resp. 16 bestående av slitesterkt og fra et friksjonssynspunkt hensiktsmessig materiale. Skoningen 15 i sporet 5 er bare anbragt ved den øvre ende av hver stigedel som vist skjematisk på fig. 2, idet skoningen 16 på skinnen 10 er anbragt ved den nedre ende av hver stigedel. På denne måte løper en stigedel i en underliggende stigedel med den minst mulige berørings-flate mellom skinne og spor. Both the track 5 and the rail 10 can at one place on the side piece be covered with a shoe 15 or 16 consisting of durable and, from a friction point of view, appropriate material. The shoe 15 in the groove 5 is only placed at the upper end of each ladder part as shown schematically in fig. 2, as the shoe 16 on the rail 10 is placed at the lower end of each ladder part. In this way, a ladder part runs in an underlying ladder part with the smallest possible contact surface between rail and track.
Fra et framstillingssynspunkt med-fører oppfinnelsen spesielle fordeler først og fremst ved at sidestykkene kan frem-stilles i så godt som komplett stand i en trekningsprosess, så etterfølgende mon-teringsarbeide blir begrenset til et mini-mum. Styrespor og skinner utformes direkte i det profilerte rør som danner sidestykket. From a production point of view, the invention brings special advantages, primarily in that the side pieces can be produced in almost complete condition in a drawing process, so that subsequent assembly work is limited to a minimum. Guide tracks and rails are designed directly in the profiled tube that forms the side piece.
Dessuten gir den valgte tverrsnitts-form av sidestykket stigen en stor stabili-tet i alle retninger, samtidig som vekten av stigen er bemerkelsesverdig lav. Særlig er dette tilfellet når sidestykkene blir utført i lettmetall, noe som også letter form-ningsarbeidet ved trekning av profilrøret. In addition, the chosen cross-sectional shape of the side piece gives the ladder great stability in all directions, while the weight of the ladder is remarkably low. This is particularly the case when the side pieces are made of light metal, which also facilitates the forming work when drawing the profile pipe.
