Den foreliggende opfindelse angår en teleskopsø j lekonstruktion f.eks. til brug i udstillingsstativer, og af den art, der er angivet i indledningen til krav 1.The present invention relates to a telescopic column construction e.g. for use in exhibition stands and of the kind specified in the preamble to claim 1.

I udstillingsstativer kan det være ønskeligt at ændre 5 eller indstille højdebeliggenheden af en fra den øvre søjledel udragende bærearm, f.eks. for højderegulering af hyldebærere eller af ophængningsindretninger for beklædningsgenstande. Det forøger anvendeligheden af udstillingsstativer, hvis disses bærende dele er højde-10 indstillelige, og medens dette er let opnåeligt ved brug af f.eks. vægmonterede, høje bæresøjler udformet med en række bærehuller til valgfri optagelse af bærekonsoller, så er det straks vanskeligere at arbejde med den art af stativer, navnlig fritstående stativer, hvor højdeind-15 stillingen udvirkes ved op- og nedføring af en teleskopsøjle i forhold til en fastholdt, evt, gulvstøttet basissøjle. Denne art af stativer har den fordel, at søjledelene ikke vil optage mere plads i højderetningen end der aktuelt er brug for, idet den øvre søjledel for oven 20 kan være permanent forsynet med en udragende bærearm, som så kan højdestilles ved en mere eller mindre vidtgående opskydning af den øvre søjledel fra basissøjledelen, der i sig selv kan være af ringe højde.In display stands, it may be desirable to change or adjust the height position of a supporting arm projecting from the upper column portion, e.g. for height adjustment of shelf carriers or of garments for garments. It increases the usefulness of display stands whose supporting parts are height-adjustable, while easily obtainable by using e.g. wall-mounted, high support columns designed with a series of support holes for optional mounting of support brackets, it is immediately more difficult to work with the kind of racks, in particular freestanding racks, where the height adjustment is effected by the up and down of a telescopic column relative to a retained, possibly, floor-supported base column. This kind of racks has the advantage that the pillar parts will not take up more space in the height direction than is currently needed, since the upper column part above 20 can be permanently provided with a protruding support arm which can then be heightened at a more or less distant projecting the upper column portion from the base column portion, which in itself may be of low height.

Ved en sådan indstilling er det meget afgørende, at 25 indstillingen, dvs. en tilhørende udløsning og genlåsning af den øvre søjledel i forhold til basisdelen, både er meget let at udføre for teknisk utrænet personale og er muliggjort ved hjælp af udløselige holdeorganer, der rent æstetisk fremtræder på yderst diskret måde.In such a setting, it is very important that the setting, i.e. an associated release and re-locking of the upper column member relative to the base member is both very easy to perform for technically untrained personnel and is made possible by releasable retaining means which appear purely aesthetically in a highly discreet manner.

30 Fra EP-A-181 584 kendes en søjlekonstruktion af den nævnte art, hvor ringlegemet er udført som en særligt formet rørbøsning, der kan hvile mod den øvre ende af den nedre rørdel. Bøsningen udvider sig lidt opefter, således at den kan vippes et stykke frem og tilbage. Ud 35 for den side af det øvre rør, som er forsynet med rækken af huller, har bøsningen ved sin øvre kant en indragende30 from EP-A-181 584 is known a column structure of the said kind, in which the annular body is designed as a specially shaped pipe sleeve which can rest against the upper end of the lower pipe part. The sleeve expands slightly upwards so that it can be tilted back and forth. Out of 35 for the side of the upper tube which is provided with the row of holes, the sleeve at its upper edge has a protruding

2 knast, der ved vipningen af bøsningen kan bringes henholdsvis ind i og ud af indgreb med det relevante hul.2 cam which can be brought into and out of engagement with the relevant hole when tilting the bush.

På den modstående inderside er anbragt en bladfjeder, der trykker bøsningen mod dens indgribende yderstilling.On the opposite inside is arranged a leaf spring which pushes the bushing towards its engaging outer position.

5 Hvis det øvre rør ønskes sænket, trykker man bøsningen over til dens modsatte yderstilling imod virkningen af fjederen og slipper bøsningen, når det nye relevante hul er ud for bøsningen. Ønskes røret hævet, kan det blot trækkes op; man kan samtidigt holde bøsningen i udløst 10 stilling, indtil den nye rørstilling er nået, eller man kan lade bøsningen følge med op, hvorefter man i den nye stilling udløser den og trækker den ned til anlæg mod enden af det nedre rør.5 If the upper pipe is desired to be lowered, push the bushing to its opposite outer position against the action of the spring and release the bushing when the new relevant hole is next to the bushing. If the tube is raised, it can simply be pulled up; you can simultaneously hold the bushing in triggered position until the new pipe position is reached, or you can let the bushing follow up, then in the new position you release it and pull it down to abutment towards the end of the lower pipe.

Ved denne kendte indretning danner bøsningen med 15 sin øvre udvidelse ikke nogen elegant afslutning på det nedre rør, og ved omstillinger skal bøsningen slæbe på det øvre rør. Hertil kommer, at bøsningen med sin irregulære form er ganske bekostelig at fremstille.In this known device, the sleeve with its upper extension does not form an elegant finish on the lower tube, and in the case of adjustments, the sleeve must drag on the upper tube. In addition, the bush with its irregular shape is quite expensive to manufacture.

Opfindelsen har til formål at angive en sådan tele-20 skopsøjlekonstruktion, ved hvilken ringlegemet er en simpel, billig enhed, som kan danne en elegant afslutning på det nedre rør og være yderst let at betjene.The invention has for its object to provide such a telescopic column structure, in which the annular body is a simple, inexpensive unit which can form an elegant end of the lower tube and be extremely easy to operate.

Dette opnås ifølge opfindelsen ved, at konstruktionen er udført som angivet i den kendetegnende del af 25 krav 1. Herved kan ringlegemet udføres, så det danner en ikke udstående, diskret randafslutning på det nedre rør, og det kan tildannes med en simpel form, f.eks. blot som et bukket trådstykke, der ikke skal være forsynet med nogen fjeder. Når det øvre rør skal hæves, trækker man 30 det blot opad, hvorved man end ikke behøver at røre ved ringlegemet, der vil virke som en løs pal, der automatisk udløses og går i indgreb med det nye udvalgte hul, når det øvre rør efter optrækningen sænkes en smule. Skal røret sænkes, må man ganske vist løfte den lave 35 side af ringlegemet op til udløst stilling, men der skal ikke herved overvindes nogen fjederkraft, og omstillin-This is achieved according to the invention in that the construction is carried out as defined in the characterizing part of claim 1. Hereby the annular body can be designed to form a non-protruding, discrete rim end on the lower pipe, and it can be formed with a simple shape, e.g. .g. just like a bent piece of wire that should not be provided with any spring. When the upper tube is to be raised, you simply pull it upwards, so that you do not even have to touch the ring body, which will act as a loose pawl, which is automatically released and engages with the new selected hole when the upper tube after the pull-up is slightly lowered. If the pipe is to be lowered, it is necessary to lift the low side of the ring body to the released position, but no spring force must be overcome and the adjustment

3 gerne kan udføres uden nogen egentlig slæbning af ring-legemet langs det øvre rør.3 can be carried out without any actual drag of the ring body along the upper tube.

Opfindelsen forklares i det følgende nærmere under henvisning til tegningen, på hvilken 5 fig. l er et perspektivisk billede af et bæreele ment til brug som eller i et udstillingsstativ, medens fig. 2-4 er tilsvarende billeder af en del af dette element vist i forskellige situationer.The invention will now be explained in more detail with reference to the drawing, in which 1 is a perspective view of a carrier for use as or in an exhibition stand, while FIG. 2-4, similar images of part of this element are shown in different situations.

Det i fig. 1 viste bæreelement er en søjledel, som 10 på forskellige måder kan være støttet i opstående stilling, og som omfatter et nedre søjlerør 2 og et deri optaget, øvre søjlerør 4, som ved sin mod højre vendende bagside er udformet med en række aflange huller 6, medens dette rør øverst har en udragende bærearm 8, der på 15 her uvæsentlig måde kan benyttes til bæring af udstillingsemner eller være forbundet med videregående bæredele. Det væsentlige er, at det øvre søjlerør 4 er optaget teleskopisk i røret 2 og kan højdeindstilles deri.The FIG. 1 is a pillar member 10 which in various ways may be supported in the upright position, comprising a lower column tube 2 and an upper column tube 4 accommodated therein, which at its rear-facing rear face is formed with a series of elongated holes 6 while this tube at the top has a protruding support arm 8 which in a non-essential way here can be used for carrying exhibition items or be connected to higher supporting parts. Essentially, the upper column tube 4 is telescopically accommodated in the tube 2 and can be height adjusted therein.

Låsningen af det øvre rør 4 i dets forskellige høj-20 destillinger udvirkes med et ringlegeme 10 placeret ved toppen af det nedre rør 2 for indgreb med et udvalgt hul 6 i det øvre rør 4, hvilket indgreb er tydeligere vist i fig 2.The locking of the upper tube 4 in its various high distances is effected by a ring body 10 located at the top of the lower tube 2 for engagement with a selected hole 6 in the upper tube 4, the engagement being more clearly shown in Figure 2.

Som det fremgår endnu klarere af fig. 3 og 4 er den 25 øvre ende af det nedre firkantrør 2 skråt afskåret mellem en vandret forkant 12 og en lavere beliggende, vandret bagkant 14, idet de skrå sidekanter er betegnet med 16. Ringlegemet 10 er ikke helt lukket, idet det dannes af et enkelt trådstykke, hvis ene endedel 18 ved bagsi-30 den er bukket indad ved midten af den pågældende side af ringlegemet, hvorved denne endedel udgør en tap, der som vist i fig. 2 kan være indragende i et af hullerne 6, når ringlegemet i en skrå stilling ligger an mod overkanten 10 af det nedre rør 2 og i denne stilling passer 35 snævert om det øvre rør 4. Ved dette indgreb af tappen 18 i hullet 6 vil røret 4 som vist være spærret modAs can be seen even more clearly in FIG. 3 and 4, the 25 upper end of the lower square tube 2 is obliquely cut between a horizontal leading edge 12 and a lower lying horizontal rear edge 14, the inclined side edges being indicated by 16. The annular body 10 is not fully closed, formed by a a single piece of thread whose end portion 18 at the back 30 is bent inwardly at the center of the respective side of the annular body, this end portion constituting a pin, as shown in FIG. 2 may be projecting into one of the holes 6 when the annular body is in an inclined position against the upper edge 10 of the lower tube 2 and in this position 35 fits snugly about the upper tube 4. In this engagement of the pin 18 in the hole 6 the tube will 4 as shown to be barred against

4 nedskydning i det nedre rør 2.4 lowering in the lower tube 2.

Man kan dog frit trække røret 4 opad, hvorved tappen 18 vil blive løftet ved et bæreindgreb med underkanten af indgrebshullet 6, således at ringlegemet som vist 5 i fig. 3 vil blive opsvunget omkring dets forreste, mod forkantdelen 12 hvilende stykke 20. Tappen 18 har en sådan afpasset længde, at afstanden mellem dens frie ende og forstykket 20 er lidt større end den modsvarende tykkelse af det øvre rør 4, dvs. under hævningen af 10 dette rør vil ringlegemet ved bagsiden blive svunget op indtil tappen 18 som vist i fig. 4 udtræder af hullet 6 og blot lægger sig løst an mod bagsiden af dette rør.However, one can freely pull the pipe 4 upwards, whereby the pin 18 will be lifted by a carrier engagement with the lower edge of the engagement hole 6, so that the ring body as shown 5 in FIG. 3 will be pivoted about its forward portion resting against the leading edge portion 12. The pin 18 is of such a length that the distance between its free end and the front portion 20 is slightly greater than the corresponding thickness of the upper tube 4, ie. during the raising of this tube, the annular body at the rear will be pivoted up to the pin 18 as shown in FIG. 4 emerges from the hole 6 and simply loosely abuts the back of this tube.

Under hævningen kan et eller flere huller 6 frit passere tappen 18, der blot midlertidigt vil indsvinges i hullet 15 og derefter igen udsvinges derfra. Når en ønsket højdestilling af røret 4 er nået kan et bæreindgreb mellem det pågældende hul og tappen 18 etableres ved en kort retursænkning af røret.During the raising, one or more holes 6 can freely pass the pin 18 which will only be temporarily pivoted in the hole 15 and then again pivoted therefrom. When a desired height position of the pipe 4 is reached, a supporting engagement between the respective hole and the pin 18 can be established by a short return lowering of the pipe.

Hvis røret 4 ønskes sænket er det tilstrækkeligt 20 først at hæve det lidt indtil den i fig. 3 og 4 viste tilstand er opnået, hvorefter man manuelt kan holde ringlegemet 10 i dets næsten vandrette fristilling, hvori det tillader fri passage af hullerne 6 for nedadgående, idet man så blot kan slippe ringlegemet, når det 25 er ønskeligt at etablere et fornyet bæreindgreb med røret 4.If the pipe 4 is desired to be lowered, it is sufficient to first raise it slightly until it is shown in FIG. 3 and 4 are obtained, after which the annular body 10 can be manually held in its almost horizontal release position, which allows free passage of the holes 6 downwards, and then only the annular body can be released when it is desirable to establish a renewed bearing engagement. with the tube 4.

Der kan eventuelt etableres en fast hængselforbindelse mellem forstykket 20 af ringlegemet 10 og den øvre forkant af det nedre rør 2, men det vil ses, at en 30 sådan forbindelse er overflødig, da det for den relevante virkning er tilstrækkeligt, at ringlegemet ved sin forkant blot hviler på den høje forkant af den øvre ende af røret 2.Optionally, a fixed hinge connection may be established between the front portion 20 of the annular body 10 and the upper leading edge of the lower tube 2, but it will be seen that such a connection is superfluous, since for the relevant effect it is sufficient that the annular body at its leading edge merely rests on the high leading edge of the upper end of the tube 2.

I fig. 5 er vist en modificeret udførelse hvor 35 forstykket af ringlegemet 10 er indlejret i en vandret indskæring 22 i forsiden af underrøret 2, medens bag-In FIG. 5, a modified embodiment is shown in which the front piece of the annular body 10 is embedded in a horizontal cut 22 in the front of the lower tube 2, while the rear

5 stykket med tappen 18 kan svinge op og ned i en højere reces 24 udformet i bagsiden af underrøret.Herved kan ringlegemet være placeret neden under den f.eks. vandret afskårne øvre ende af underrøret. Det er herved ikke 5 afgørende at den bageste ende af ringlegemet er understøttet med en kantdel af det nedre rør 2, da der alligevel kan etableres et bæreindgreb mellem røret 4 og det ved forstykket 20 understøttede ringlegme. Omvendt vil netop denne understøtning være uden særlig betydning, 10 hvis tappen 18 kan ligge an mod den bageste kant af det nedre rør 2.The piece with the pin 18 can swing up and down in a higher recess 24 formed in the back of the lower tube. horizontally cut upper end of lower tube. It is therefore not essential that the rear end of the annular body is supported with an edge part of the lower tube 2, since a support can still be established between the tube 4 and the annular body supported by the front 20. Conversely, this particular support will be of no particular significance if the pin 18 can abut the rear edge of the lower tube 2.

Opfindelsen er ikke begrænset til udstillingsstativer, da man også ved andre former for standere eller teleskopsystemer kan drage fordel af det enkle arrange-15 ment ifølge opfindelsen.The invention is not limited to display stands, as the simple arrangement according to the invention can also benefit from other types of stands or telescopic systems.
