TEKNIKKENS STANDPUNKTBACKGROUND OF THE ART

Der kendes i dag adskillige forskellige udførelsesformer for rørformede nøglebokse af den ovennævnte art. Disse rørformede nøglebokse har det til fælles at de er tiltænkt montering i en murkonstruktion eller anden bygningsdel ved at der først tildannes et hul i murkonstruktionen, som har en sådan størrelse og form at det tillader at den rørformede nøgleboks netop kan indføres i hullet, hvorefter den rørformede nøgleboks kan fastgøres i murkonstruktionen ved brug af de nævnte fastgørelsesmidler.Today, several different embodiments of tubular key boxes of the above kind are known. These tubular key boxes have in common that they are intended to be mounted in a wall structure or other building part by first forming a hole in the wall structure which is of such size and shape as to allow the tubular key box to be inserted precisely into the hole, after which it is inserted. tubular key box may be secured to the wall structure using said fasteners.

Eksempler på de førstnævnte bølgeenergianlæg kendes f.eks. fra DK brugsmodel nr. 200500079, og fra EP patent nr. 90675, som begge er indrettet med fastgørelsesmidler, som er indrettet på en sådan måde at man ved tilspænding af en bolt i rørboksens bundplade kan bevirke at et fastgørelses-element deformeres således at det delvist forskydes radialt udad og dermed trykkes ud mod den omgivende murkonstruktion.Examples of the first-mentioned wave energy systems are known e.g. from DK utility model no. 200500079, and from EP patent no. 90675, both of which are provided with fasteners which are arranged in such a way that, by tightening a bolt in the bottom plate of the pipe box, a fastening element can be deformed so that it partially displaced radially outward and thus pushed out against the surrounding wall structure.

Det ovennævnte EP patent beskriver i denne sammenhæng specielt anvendelsen af et bukket stykke metal, som har to modsat orienterede ender der ligger an mod bunden af rørboksen, og ved belastning forskydes radialt ud fra bunden af rørboksen hvor ender trykkes ind mod indersiden af hullet i murkonstruktionen. Et problem med denne løsning er at fastgørelsesmidlerne ikke fungerer i f.eks. en hul murkonstruktion, hvor rørboksen strækker sig ind i hulrummet i murkonstruktionen.In this context, the above-mentioned EP patent specifically describes the use of a curved piece of metal having two oppositely oriented ends abutting the bottom of the tube box and, under load, being radially displaced from the bottom of the tube box where ends are pressed against the inside of the hole in the wall structure. . One problem with this solution is that the fasteners do not work in e.g. a hollow wall structure wherein the tube box extends into the cavity of the wall structure.

Den ovennævnte DK brugsmodel angiver således en løsning på dette problem, hvorved der er tilvejebragt et fastgørelsesrør på ydersiden af rørboksen, hvilket fastgø reises rør er forsynet med svækkelseslinier indrettet således at røret ved en stor aksialt orienteret kraftpåvirkning vil kollapse omkring svækkelseslinierne, således at dele af fastgørelsesrøret trykkes radialt udad til anlæg mod indersiden af hullet i murkonstruktionen.The above-mentioned DK utility model thus provides a solution to this problem whereby an attachment tube is provided on the outside of the tube box, which attaches raised tubes are provided with weakening lines arranged so that the tube will collapse around the lines of weakening by a large axially oriented force. the attachment tube is pressed radially outward to abut the inside of the hole in the wall structure.

En konstant udfordring ved udvikling af rørbokse af denne type, er at tilvejebringe rørbokse med en fastgørelsesindretning som er universelt anvendelig, således at en enkelt udførelse af rørboksen er anvendelig til fastgørelse i flere forskellige murtyper, samtidig med at der, med simple midler, sikres en effektiv fastholdelse af rørboksen i murkonstruktionen,A constant challenge in the development of pipe boxes of this type is to provide pipe boxes with a fastening device which is universally applicable, so that a single embodiment of the pipe box is applicable for fastening in several different types of walls, while ensuring, with simple means, a effective retention of the pipe box in the wall structure,

OPFINDELSENS FORMALFORMAL OF THE INVENTION

Det er derfor på denne baggrund formålet med den foreliggende opfindelse at angive en rørboks af den indledningsvist anførte art, som med simple midler afhjælper de ovennævnte problemer.Accordingly, it is the object of the present invention to provide a tube box of the kind initially provided which, by simple means, solves the aforementioned problems.

Dette opnås ved en rørboks af den art der angives i indledningen, og hvor rørboksen yderligere er speciel ved at der at der på ydersiden af yderrøret i afstand fra både den åbne ende og den lukkede ende er indrettet en aftrapning, således at den ydre diameter på det ydre rør mellem aftrapningen og den lukkede.ende er mindre end den største ydre diameter på den modsatte side af aftrapningen, og hvor fastgørelsesmidlerne omfatter et fastgørelses- 3 DK 2009 00067 U3 rør som strækker sig uden på yderrøret fra den bageste ende og fremad mod aftrapningen, og hvor der er indrettet midler til at forskyde fastgørelsesrøret frem mod aftrapningen med en sådan kraft at fastgørelsesrøret deformes ved anlæg mod aftrapningen.This is achieved by a tube box of the kind specified in the preamble, and wherein the tube box is further special in that a step away from both the open end and the closed end is arranged in a step so that the outer diameter of the the outer tube between the taper and the closed end is smaller than the largest outer diameter on the opposite side of the taper, and the fasteners comprise a fastener extending beyond the outer tube from the rear end forward. the step, and where means are provided for displacing the fastener tube towards the step with such force that the fastener tube is deformed by abutment against the step.

I situationer hvor rørboksen tænkes monteret specielt i en murkonstruktion bestående af mursten, da vil det være specielt fordelagtigt såfremt aftrapningen er placeret i det mindste 1 cm. og fortrinsvis mellem 3 og 8 cm. fra yderrørets forkant, således at der opnås en god fastholdelse, samtidig med at risikoen, for at ødelægge den eller de mursten hvori rørboksen monteres, er minimeret.In situations where the pipe box is thought to be mounted especially in a brick structure consisting of bricks, then it will be especially advantageous if the step is at least 1 cm. and preferably between 3 and 8 cm. from the leading edge of the outer tube, so that good retention is achieved while minimizing the risk of destroying the brick (s) in which the tube box is mounted.

I en specielt fordelagtig udførelse, da er aftrapningen udformet skrå, således at fastgørelsesrørets forreste kant som ligger an mod aftrapningen, forskydes radialt udad når den forreste kan trykkes ind mod aftrapningen.In a particularly advantageous embodiment, the tapping is configured obliquely so that the front edge of the attachment tube abutting the tapping is displaced radially outward when the front can be pressed into the tapping.

I denne sammenhæng er det yderligere fordelagtigt såfremt fastgørelsesrøret i den ende der vender mod aftrapningen, er forsynet med langsgående slidser.In this connection, it is further advantageous if the fastening tube at the end facing the step is provided with longitudinal slots.

Der kan opnås en specielt enkelt metode til fastgørelse af rørboksen i en mur, såfremt midlerne til at forskyde fastgørelsesrøret omfatter at fastgørelsesrøret har en bundplade der helt eller delvist lukker den ende der vender bort fra aftrapningen, og hvor der er en eller flere spændbolte, som hver er indrettet således at de kan tilspændes fra yderrørets indre, og hvor hver spændholt strækker sig frit forskydeligt gennem yderrørets bundplade, og derefter strækker sig gevindført gennem fastgørelsesrørets bundplade.A particularly simple method can be obtained for securing the tube box to a wall, if the means for displacing the fastening tube comprise that the fastening tube has a bottom plate which completely or partially closes the end facing away from the step and where there are one or more clamping bolts which each is arranged so that they can be tightened from the interior of the outer tube, and each tensioning cavity extends freely displaceably through the bottom plate of the outer tube, and then extends threaded through the bottom plate of the fastening tube.

UDFØRELSESFORM FOR OPFINDELSENEMBODIMENT OF THE INVENTION

På fig. 1 ses således en rørformet nøgleboks ifølge opfindelsen, set fra siden, og hvor nøgleboksen omfatter et yderrør 1, som fortil har en åbning 7 placeret i den ene ende for indføring af et ikke vist dæksel. Nøgleboksen har yderligere et fastgørelsesrør 2, som v.h.a. spændbolten 3 kan forskydes og presses hen mod aftrapningen 6, som deler yderrøret 1 i en forreste ende og en bageste ende, som fastgørelsesrøret 2 delvist omslutter. Ifølge opfindelsen har den bageste ende på yderrøret et reduceret tværmål end det tilsvarende største tværmål på den forreste ende på yderrøret. I den viste udførelsesform er både yderrøret 1 og fastgørelsesrøret 2 udført i et hovedsageligt cirkulærcylindrisk tværsnit, således at tværmålet svarer til diameteren på rørene 1,2In FIG. 1, a tubular key box according to the invention is seen from the side, the key box comprising an outer tube 1 having a front opening 7 located at one end for insertion of a cover not shown. The key box further has an attachment tube 2 which, e.g. the clamping bolt 3 can be displaced and pressed against the step 6 which divides the outer tube 1 at a front end and a rear end, which the securing tube 2 partially encloses. According to the invention, the rear end of the outer tube has a reduced cross-section than the corresponding largest cross-section of the front end of the outer tube. In the embodiment shown, both the outer tube 1 and the attachment tube 2 are formed in a substantially circular cylindrical cross-section such that the cross-section corresponds to the diameter of the tubes 1,2

Fastgørelsesrøret 2, som i øvrigt er vist som en selvstændig komponent på fig. 2, er i den ende der vender mod den forreste ende på yderrøret 1 forsynet med slidser 4 som adskiller fastgørelsesrøret i et antal tunger 5, som når fastgørelsesrøret 2 ved hjælp af spændbolten 3 forskydes med stor kraft frem i retning mod yderrørets 1 forreste ende, vil blive presset hårdt in mod aftrapningen 6 som i denne udførelsesform strækker sig ubrudt hele vejen rundt om yderrøret 1. Fastgørelsesrøret 2 vil således deformeres, således at det vil lægge an med stor kraft mod en omgivende murkonstruktion (ikke vist).The attachment tube 2, which is otherwise shown as an independent component in FIG. 2, at the end facing the front end of the outer tube 1 is provided with slots 4 separating the fastening tube in a plurality of tongues 5, which when the fastening tube 2 is displaced with great force forward towards the front end of the outer tube 1, will be pressed hard against the step 6 which in this embodiment extends unbroken all the way around the outer tube 1. The fixing tube 2 will thus deform so that it will apply with great force to a surrounding wall structure (not shown).

Aftrapningen 6 på yderrøret er i den viste udførelsesform udformet således at den har en vinkel i forhold til yderrørets overflade, således at tungerne 5, når de presses ind mod aftrapningens overflade, vil blive tvunget udad og evt. bliver plastisk deformeret, således at de graver sig ind i den omgivende mur-5 konstruktionen, hvorved der er opnået en effektiv fastholdelse af rørboksen i muren.The tapping 6 on the outer tube is designed in the illustrated embodiment so that it has an angle to the surface of the outer tube, so that the tongues 5, when pressed against the surface of the tapping, will be forced outwards and possibly. are deformed plastically so that they dig into the surrounding wall structure, thereby providing an effective holding of the tube box in the wall.

På fig. 3 ses herefter yderrøret ifølge fig. 1, men her er det vist som en snit-tegning langs med symmetriaksen for yderrøret. Her ses det at yderrøret 1, 10 bagved åbningen 7, har en indre slids 9 for optagelse af et kamstykke på et dæksel, som yderligere er forsynet med en låsecylinder som kan forskyde kamstykket til låsning eller åbning af nøgleboksen. Idet fagmanden naturligt kan foreslå mange alternative løsninger og udformninger for dæksler med tilhørende låsecylindre og kamstykker, f.eks. som det vises i den kendte tek-15 nik ifølge DK brugsmodel nr. 200500079 eller EP patent nr. 90675, så vises dette ikke på tegningen.In FIG. 3, the outer tube of FIG. 1, but here it is shown as a sectional view along the axis of symmetry of the outer tube. Here it is seen that the outer tube 1, 10 behind the opening 7 has an inner slot 9 for receiving a cam piece on a cover, which is further provided with a locking cylinder which can displace the cam piece for locking or opening the key box. As the person skilled in the art can naturally propose many alternative solutions and designs for covers with associated locking cylinders and comb pieces, e.g. as shown in the prior art according to DK utility model no. 200500079 or EP patent no. 90675, this is not shown in the drawing.

Dette er klart at fagmanden uden at fravige det grundlæggende princip for den foreliggende opfindelse, kan angive andre udformninger for nøglebokse. 20 F.eks. kan nøgleboksen have et tværsnit som ikke er cirkulærcylindrisk, og antallet at slidser 4 og tunger 5 kan varieres afhængigt af behov.It is clear that, without departing from the basic principle of the present invention, the person skilled in the art can specify other designs for key boxes. For example, For example, the key box may have a cross-section which is not circular cylindrical and the number of slots 4 and tongues 5 may be varied according to need.
