Opfindelsen angår en stige, især metalstige af den art, der har to parallelle vanger, hvorimellem der strækker sig et antal tværstivere, som danner stigens trin, hvilken stige er forbundet med bæreorganer, der er indrettede til at blive fastgjort på en mur eller et lignende bygningselement.BACKGROUND OF THE INVENTION 1. Field of the Invention This invention relates to a ladder, in particular metal ladder of the type having two parallel bars, between which extends a plurality of transverse struts forming the ladder steps, which ladder is connected to supporting means adapted to be secured to a wall or the like. building element.
For at lette skorstensfejerens arbejde og formindske risikoen derved, forsynes huse ofte med fastsiddende stiger, der har en lodret del, der er fastgjort til muren ved hjælp af bæreorganer, og ofte en dertil sluttet skrå del, der ligger på en skrå del af taget. Formålet med nærværende opfindelse er at tilvejebringe en stige, som med enkle midler kan fastgøres sikkert på en mur eller et lignende bygningselement.To facilitate the work of the chimney sweeper and to reduce the risk thereof, houses are often provided with fixed ladders having a vertical portion attached to the wall by means of supports, and often a sloping portion connected thereto which is on an inclined portion of the roof. The object of the present invention is to provide a ladder which can be secured securely to a wall or similar building element by simple means.
Stigen ifølge opfindelsen er ejendommelig ved, at hvert bæreorgan består af to konsoller, der hver er dannet af to skråstænger, hvis længst fra bygningselementet beliggende ender er forbundet med en af stigens vanger i et fælles punkt, medens de to skråstængers modsatte ender er indrettede til at blive fastgjort i væsentlig lodret afstand fra hinanden til bygningselementet, hvorhos en tværstang forbinder et forbindelsespunkt på en vange med et diagonalt modsat liggende forbindelsespunkt med bygningselementet .The ladder according to the invention is characterized in that each support member consists of two brackets, each formed of two inclined rods, the furthest ends of the building element being connected to one of the ladders at a common point, while the opposite ends of the two inclined rods are arranged to being fixed at substantially vertical distance from each other to the building element, wherein a cross bar connects a connecting point on a vane with a diagonally opposite connecting point to the building element.
Herved åbnes der mulighed for en god og stabil fastgørelse af stigen på en mur eller et lignende bygningselement ved hjælp af enkle midler, hvilket især skyldes opbygningen af bæreorganerne af to konsoldele, der hver består af to skråstænger, og af en tværstang. Tværstangen hindrer konsoldelene i at dreje omkring hver sin lodrette akse medens skråstængerne hindrer drejning omkring en vandret akse.This allows for a good and stable attachment of the ladder to a wall or similar building element by simple means, which is mainly due to the construction of the supporting members of two bracket parts, each consisting of two sloping rods and of a cross bar. The transverse bar prevents the bracket members from rotating about their vertical axis while the inclined bars prevent rotation about a horizontal axis.
Ved udførelsesformen ifølge krav 2 forenkles bæreorganerne, i-det de kommer til at bestå af forholdsvis få rørdele, som næsten alle er ens, og som let kan samles og forbindes med stigens vanger og bygningselementet.In the embodiment according to claim 2, the supporting members are simplified in that they are made up of relatively few pipe parts, which are almost all the same, and which can be easily assembled and connected to the rails of the ladder and the building element.
Ved udførelsesformen ifølge krav 3 opnås en god stiv og enkel 2 142246 forbindelse imellem konsollerne og stigen.In the embodiment of claim 3, a good rigid and simple connection is obtained between the brackets and the ladder.
I det følgende forklares opfindelsen under henvisning til tegningen, hvor fig. 1 viser skematisk en stige ifølge opfindelsen set forfra, fig. 2 det samme set fra siden, fig. 3 en stigeséktion set forfra i større målestok, fig. 4 en øverste del af et bæreorgan og en stigesektion set fra oven og fig. 5 et bæreorgan set forfra i større målestok.In the following, the invention is explained with reference to the drawing, in which 1 is a schematic front view of a ladder according to the invention; FIG. 2 shows the same side view; FIG. 3 is a front elevation section on a larger scale; FIG. 4 is a top view of a support member and a ladder section, and FIG. 5 is a front elevation on a larger scale.
Stigen, der som helhed er betegnet med 1, er sammenbygget af et antal sektioner, hvoraf én er vist på fig. 3. Stigesektionen, som er betegnet med 2, består af to parallelle vanger 3, der hver er dannet af en metalprofilskinne med en flad kropdel, som står vinkelret på stigens plan. Imellem vangerne strækker der sig fire tværstivere 4, som danner stigens trin, og som består af rør, hvis ender er fastgjort i vangerne 3, fortrinsvis ved vals-ning og stukning.The ladder, which is generally denoted by 1, is joined by a number of sections, one of which is shown in FIG. 3. The ladder section, denoted by 2, consists of two parallel bars 3, each formed of a metal profile rail with a flat body part perpendicular to the plane of the ladder. Between the bars there are four transverse struts 4 which form the steps of the ladder, and which consist of tubes whose ends are fixed in the bars 3, preferably by rolling and pruning.
Sektionerne 2 er forbundet med hinanden ved hjælp af laskeplader 5, som er fastgjort til vangerne 3's kropdel ved hjælp af nitter eller bolte, og de udragende ender af laskepladerne 5 er forsynet med huller, således at de ved hjælp af bolte kan forbindes med en anden lignende sektion.The sections 2 are connected to each other by means of wafer plates 5, which are attached to the body part of the vanes 3 by means of rivets or bolts, and the projecting ends of the wafer plates 5 are provided with holes so that they can be connected with another by means of bolts. similar section.
Stigen er indrettet til at blive permanent fastgjort på en mur 6 eller et andet bygningselement, og den på fig. 1 og 2 viste stige bæres af to bæreorganer 7, der hvert består af to konsoller, én på hver side af stigen. Hver konsol er dannet af to skråstænger 8, som består af rør, hvis endedele er presset sammen til dannelse af flanger 9, ved hjælp af hvilke skråstængerne er fastgjort henholdsvis til muren 6 og til en vange 3.The ladder is arranged to be permanently attached to a wall 6 or other building element, and the one shown in FIG. 1 and 2 are supported by two supporting members 7, each consisting of two brackets, one on each side of the ladder. Each bracket is formed of two sloping rods 8, which consist of tubes whose end portions are compressed to form flanges 9, by means of which the sloping rods are attached respectively to the wall 6 and to a bar 3.

De to konsoller 7' er indbyrdes forbundet ved hjælp af en tværstang 10, der ligeledes er et rør, hvis ender er klemt sammen til dannelse af flanger.The two brackets 7 'are interconnected by means of a crossbar 10, which is also a tube whose ends are clamped together to form flanges.
Af fig. 5 fremgår det tydeligt, hvorledes stængerne er udformet og forbundet med henholdsvis stigens vanger 3 og muren, som er repræsenteret af papirets plan.In FIG. 5 it is clear how the rods are designed and connected to the ladders 3 of the ladder and the wall respectively represented by the plane of the paper.
De fire skråstænger 8 i hvert bæreorgan er identiske, idet flangerne 9 er drejet til siden, således at den flange, der ligger op ad flangen på tværstangen 10, i hovedsagen flugter med denne, som det er vist i det øverste højre hjørne på fig. 5. Det ses således, at den pågældende skråstang 8 og tværstangen 10 kan fastgøres til muren ved hjælp af en enkelt bolt, der strækker sig igennem flugtende huller i de to flanger 9.The four sloping rods 8 in each support member are identical, with the flanges 9 being turned to the side so that the flange lying upwards on the flange of the transverse rod 10 is substantially flush with it, as shown in the upper right corner of FIG. 5. Thus, it is seen that the respective inclined rod 8 and the transverse rod 10 can be secured to the wall by a single bolt extending through flushing holes in the two flanges 9.
I den højre side af fig. 5 ses to flanger 9 på de to skråstænger 8 liggende op ad hinanden og imod enden af trinet 4 eller et imellem dette og flangerne anbragte afstandsorgan 11. I venstre side af figuren ligger de to flanger på skråstængerne 8 i-mod hinanden; imod den inderste flange ligger tillige flangen på tværstangen 10. Delene sammenspændes ved hjælp af en stagbolt 12, der strækker sig igennem de nævnte dele og røret, der danner trinet 4, og sammenspændingen foretages ved hjælp af en møtrik 13 på stagbolten. Ved hjælp af denne forbindelse og tværstangen 10 tilvejebringes der et stift og stabilt bæreorgan for stigen.In the right side of FIG. 5, two flanges 9 are seen on the two sloping rods 8 adjacent to each other and towards the end of the step 4 or a spacer 11 arranged between them and the flanges. In the left side of the figure the two flanges of the sloping rods 8 lie opposite each other; against the inner flange also lies the flange on the transverse rod 10. The parts are clamped by means of a stag bolt 12 extending through said parts and the tube forming the step 4, and the clamping is carried out by means of a nut 13 on the stag bolt. By means of this connection and the transverse rod 10, a rigid and stable carrier for the ladder is provided.
