INDRETNING AF FQLDELIGE DØRPARTIER, FORTRINSVIS I KØRETØJERFACILITIES OF MULTIPLE DOOR PARTS, PRIOR TO VEHICLES

Nærværende opfindelse vedrører en indretning af hjulbårne, 5 fortrinsvis trukne køretøjer, hvis chassis bærer et skabs-lignende rum, hvis i det mindste ene langside kan åbnes og lukkes ved hjælp af et dørparti eller fortrinsvis to dørpartier af den art, hvor hvert dørparti består af et antal med hverandre ledforbundne elementer, hvoraf i det mindste 10 nogle er bevægeligt forbundne med skabsdelens øvre, langsgående del, hvorhos et i den ydre ende anbragt dørelement i hvert dørparti virker sammen med en som dørkarm fungerende, fast monteret lodret stander.The present invention relates to an arrangement of wheel-borne, 5 preferably towed vehicles, the chassis of which carries a cabinet-like compartment whose at least one long side can be opened and closed by means of a door portion or preferably two door sections of the kind in which each door portion consists of a plurality of interconnected members, at least some of which are movably connected to the upper, longitudinal portion of the cabinet portion, wherein a door member located at the outer end of each door portion cooperates with a door frame operating as a fixed vertical stand.

15 Skabsvogne eller køretøjer, ofte trukne køretøjer, af o-vennævnte art, konstrueres for at kunne rumme og beskytte store lastemner, og deres længde varierer normalt fra 6 meter og opefter. For at gøre skabsrummet let tilgængeligt er disse køretøjers ene eller to langsider forsynede med 20 et foldedørssystem, sædvanligvis opbygget af dørpartier, der åbnes i hinanden modsat rettede retninger på sædvanlig foldedørsmaner. Hele køretøjets langside kan på denne måde gøres tilgængelig for af- og pålæsning.15 Cabinets or vehicles, often towed vehicles, of an o-friend type, are designed to accommodate and protect large cargo items, and their length usually varies from 6 meters upwards. To make the locker room easily accessible, one or two long sides of these vehicles are provided with a folding door system, usually constructed of door portions which open in opposite directions in the usual direction of conventional folding door manners. In this way, the entire long side of the vehicle can be made available for loading and unloading.

25 De kendte konstruktioner har imidlertid den ulempe, at de, såfremt køretøjet udsættes for ujævn belastning, eller såfremt det står på ujævnt underlag, vanskeligt kan lukkes respektivt åbnes. Denne ulempe beror på skabsdelens opbygning, og ulempen optræder nærmere specificeret, når de 30 langsgående bærebjælker henholdsvis det til bjælkerne fastgjorte tag udsættes for vridnings- og forskydningsmomenter. Fordi dørpartierne sædvanligvis er ophængt i taget, der på sin side er fastgjort til bærebjælkerne, forskydes også dørpartierne mere eller mindre afhængigt af 35 den hældning/vridning, som skabsdelen udsættes for, og i25 However, the known constructions have the disadvantage that, if the vehicle is subjected to uneven loading, or if it is on uneven ground, they can be difficult to close or open, respectively. This disadvantage is due to the structure of the cabinet part, and the disadvantage occurs more specifically when the 30 longitudinal beams or the roof fixed to the beams are subjected to torsional and shear moments, respectively. Because the door portions are usually suspended in the roof, which in turn is attached to the supporting beams, the door portions are also more or less displaced depending on the inclination / twist to which the cabinet part is exposed and in

uheldigste tilfælde kan dørpartierne ikke bevæges, før køretøjet er transporteret hen til et jævnt underlag, eller før belastningen er ændret. Såfremt forskydningen er meget stor, kan taget endda deformeres.In the unfortunate case, the door sections cannot be moved until the vehicle has been transported to a level surface or before the load has changed. If the displacement is very large, the roof can even be deformed.

5 Målet med nærværende opfindelse er at anvise en indretning, som overvinder ovenfor anførte ulempe, og som følgelig eliminerer køretøjets følsomhed over for underlagets natur respektive køretøjets belastning.The object of the present invention is to provide a device which overcomes the disadvantage mentioned above and consequently eliminates the sensitivity of the vehicle to the nature of the underlay and the load of the vehicle.

Problemet løses ved en indretning af den indledningsvist angivne art, hvilken indretning ifølge opfindelsen er særegen ved, at det ydre dørelements lodrette endeparti over et hængsel er sluttet til et parallelt eller i hovedsagen 15 parallelt med standeren forløbende mellemstykke, der på sin side over en horisontal tap er ledforbundet med standeren, at et trykeelement, som udøver en horisontal trykkraft, ligger an mod mellemstykket og standeren for at holde hvert dørparti i horisontal stilling, hvorhos mel-20 lemstykkets endepartier er anbragt i afstand til skabs-konstruktionens øvre, respektive nedre, fast anbragte dele.The problem is solved by a device of the type mentioned in the preamble, which device is characterized in that the vertical end portion of the outer door element is connected over a hinge to a parallel or generally parallel parallel to the standard, which in turn over a horizontal pin is articulated to the stand that a pressure member exerting a horizontal compressive force abuts the spacer and the stand to hold each door portion in a horizontal position, the end portions of the spacer being spaced apart from the upper and lower members of the cabinet structure, respectively; fixed parts.

En foretrukken udformning af opfindelsen beskrives neden-25 for med henvisning til vedlagte skematiske tegning, hvor fig. 1 viser en skabsvogn med i det mindste et sideparti, der kan åbnes, 30 fig. 2 er en tegning af enden af et dørparti, fig. 3 er et snit langs linien III-III i fig. 2, fig. 4 er et snit langs linien IV-IV i fig. 2.A preferred embodiment of the invention is described below with reference to the accompanying schematic drawings, in which: Fig. 1 shows a cupboard with at least one openable side portion; 2 is a drawing of the end of a door portion; FIG. 3 is a section along line III-III of FIG. 2, FIG. 4 is a section along the line IV-IV of FIG. 2nd

Et køretøj, fortrinsvis men ikke udelukkende et trukket, betegnes med 10, og det bæres af et antal roterbare hjul 11, som på kendt måde er anbragte på hjulaksler 12. Køretøjets 10 i og for sig kendte chassiskonstruktion bærer en 5 skabslignende del bestående af gavldele 12, tag 13 og ved hjælp af to dørpartier 14, 15 i det mindste en langside, der kan åbnes og lukkes, samt af en til dørpartierne modstående langside, der kan være en fast væg. Gavlsider og tag er fast sammenkoblede med lodrette og vandrette bære-10 bjælker.A vehicle, preferably but not exclusively a tow, is designated 10, and it is carried by a plurality of rotatable wheels 11, which are known in a known manner on wheel axles 12. The vehicle structure 10, known per se, carries a cabinet-like part consisting of gable parts. 12, roof 13 and by means of two door portions 14, 15 at least one longitudinally openable and closed side, and one longitudinal side opposite to the door portions which may be a fixed wall. Gable sides and roofs are firmly interconnected with vertical and horizontal support-10 beams.

Et dørparti 14 (15) er opbygget med et antal med hverandre med led 16 forbundne dørelementer 17 (fig. 4). Et ydre dørelement i hvert dørparti er ved hjælp af et hængsel 18 15 (fig. 3) forbundet med et mellemstykke 19, der løber parallelt eller i hovedsagen parallelt med en stander 20, som er fast monteret, og som kan være en del af skabsde-lens struktur, og som har form af en U-bjælke med åbningen i længderetningen mod køretøjets modsatte ende. Mellem-20 stykket 19 har form af et rektangulært rør, og det er ek-centrisk og bevægeligt forbundet med standeren 20 ved hjælp af en tap 21.A door portion 14 (15) is constructed with a plurality of door elements 17 interconnected with links 16 (Fig. 4). An outer door element in each door portion is connected by means of a hinge 18 (Fig. 3) to an intermediate piece 19 running parallel or substantially parallel to a stand 20 which is fixedly mounted and which may be part of cabinet doors structure, which is in the form of a U-beam with the longitudinal opening towards the opposite end of the vehicle. The intermediate piece 19 is in the form of a rectangular tube and is eccentrically and movably connected to the stand 20 by means of a pin 21.

Mellemstykket 19 har en lodret udstrækning, således at der 25 er frigang mellem begge dets endedele og skabsdelens øvre respektive nedre del.The spacer 19 has a vertical extension so that there is clearance between both of its end portions and the upper and lower portions of the cabinet portion, respectively.

Den ovenfor beskrevne forbindelse mellem standeren 20 og mellemstykket 19 er i en foretrukken udformning placeret 30 omtrent i standerens 20 vertikale midre. Givetvis kan forbindelsen placeres anderledes, og dens udformning kan være anderledes.The connection described above between the stand 20 and the stand 19 is in a preferred embodiment 30 approximately in the vertical center of the stand 20. Of course, the connection can be positioned differently and its design may be different.

En trykfjeder 22 ligger an mod det rørformede mellemstykke 35 19 og standeren 20, og fjederens 22 dimensionering er af-A compression spring 22 abuts the tubular spacer 35 19 and the stand 20, and the dimension of the spring 22 is removed.

hængig af de beregnede belastninger, og af vægten af dørpartiet. Formålet med trykfjederen er at holde dørpartiet i korrekt, vandret stilling.depending on the calculated loads, and the weight of the door portion. The purpose of the compression spring is to keep the door portion in the correct, horizontal position.

5 I det mindste nogle af de i et dørparti indgående elementers 17 øvre kant virker sammen med i sig selv kendte styringer i skabsdelens tag i dettes ydre dels indadvendende side. Nedadtil løber elementerne 17 frit og kan tætnes med ikke viste gummilister mod skabsydersiden.5 At least some of the upper edge of a member of a door portion 17 extends together with self-guided controls in the roof of the cabinet part in the outer side of the outer part thereof. Downwards, the elements 17 run freely and can be sealed with rubber strips not shown towards the cabinet side.

10 Såfremt et køretøj med det ovenfor beskrevne dørarrangement eksempelvis placeres på et så ujævnt underlag, at de indledningvis anførte forskydninger/vridninger optræder, overføres disse til det respektive dørparti via de opadtil 15 placerede dørføringer, men derfra overføres de til mellemstykket 19, som på grund af den frigang, der findes mellem dettes endedele og skabets over- respektive underkant og gennem fjederen 22 fungerer som en opretningsindretning for dørpartierne via leddet 21.If, for example, a vehicle with the door arrangement described above is placed on such an uneven surface that the initially stated displacements / torsions occur, these are transmitted to the respective door portion via the upwardly facing door guides, but from there they are transferred to the intermediate piece 19, which of the clearance found between its end portions and the upper and lower edges of the cabinet and through the spring 22 acts as a rectifying device for the door portions via the link 21.

2020

Den ekcentriske befæstigelse mellem standeren 20 og mellemstykket medfører, at mellemstykket 19 og følgeligt også det med dette forbundne dørparti vippes omkring tappen 21, og dermed absorberes alle formforandringer af 25 mellemstykket 19 uanset retning.The eccentric attachment between the stand 20 and the spacer causes the spacer 19, and consequently also the door portion associated with it, to tilt around the pin 21, and thus all shape changes are absorbed by the spacer 19 regardless of direction.

Den ovenfor anførte frigang, som mellemstykket 19 har, er dimensioneret for at kunne optage de maksimale vridningsbevægelser i skabskonstruktionen.The clearance stated above, which the spacer 19 has, is sized to accommodate the maximum torsional movements in the cabinet structure.
