Description
Foreliggende oppfinnelse angår et sikkerhetsgitter av den type som er angitt i innledningen til det etterfølgende patentkrav. The present invention relates to a safety grid of the type specified in the introduction to the subsequent patent claim.
Et slikt sikkerhetsgitter er kjent fra DK-utlegningsskrift nr. 154717. Such a safety grid is known from DK design document no. 154717.
Sikkerhetsgitter av denne type monteres f.eks. bak glassruten i utstillingsvinduer i forretninger, og de skal forhindre at tyver får adgang til de utstilte varer etter at glassruten er slått istykker. Safety grilles of this type are installed, e.g. behind the pane of glass in display windows in shops, and they must prevent thieves from gaining access to the displayed goods after the pane of glass has been smashed.
Sikkerhetsgitteret er normalt opprullet på en trommel i åpningstiden og nedrullet etter stengetid. Sikkerhetsgitteret er låst i den nedrullede stilling av en trommelbrems, slik at det ikke kan løftes opp utenfra. Den foranliggende glassrute kan være koblet til et alarmanlegg, slik at en alarm aktiveres og politiet eller en sikkerhetsvakt blir tilkalt dersom ruten slås i stykker. Sikkerhetsgitteret skal derfor være gjennomsiktig, samtidig med at det sperrer for adgangen til de utstilte varer i lengst mulig tid etter at glassruten er slått i stykker. The safety grid is normally rolled up on a drum during opening hours and rolled down after closing time. The safety grid is locked in the rolled-down position by a drum brake, so that it cannot be lifted from the outside. The front glass pane can be connected to an alarm system, so that an alarm is activated and the police or a security guard is called if the pane is broken. The safety grid must therefore be transparent, while at the same time blocking access to the exhibited goods for the longest possible time after the glass pane has been broken.
Broelementene i dette kjente gitter er fremstilt av stål eller aluminium. Broelementene har et konvekst midtparti, som har skarpe overganger til vulstene. Dette bevirker kjerwirkning og spenningskonsentrasjon i disse overganger. The bridge elements in this known grid are made of steel or aluminium. The bridge elements have a convex middle section, which has sharp transitions to the beads. This causes core action and stress concentration in these transitions.
Et formål med den foreliggende oppfinnelse er å komme frem til et sikkerhetsgitter som har bedre sikkerhet mot å kunne brytes opp, og som muliggjør at broelementene også har høy styrke når de er fremstilt av polykarbonat, slik at gitteret delvis er An aim of the present invention is to arrive at a safety grid that has better security against being broken up, and which enables the bridge elements to also have high strength when they are made of polycarbonate, so that the grid is partly
gjennomsiktig. transparent.
Som andre eksempler på kjent teknikk skal nevnes følgende: The following should be mentioned as other examples of known technology:
Fra GB-patentsøknad med publ. nr. 2120306 er det kjent et sikkerhetsgitter som består av flere gjennomsiktige, like lange paneler, som ved hver ende er hengslet i metallskinner. Dette kjente sikkerhetsgitter er således helt lukket, men det er en ulempe ved dette gitter at det i opprullet tilstand vil få store ytre tverrmål i forhold til panelbredden, og dessuten kommer noen av metallskinnene i opprullet tilstand til anlegg mot panelene, slik at disse kan bli skadet. From GB patent application with publ. No. 2120306, a safety grid is known which consists of several transparent, identical long panels, which are hinged at each end in metal rails. This known safety grid is thus completely closed, but there is a disadvantage of this grid that in the rolled-up state it will have large outer transverse dimensions in relation to the panel width, and furthermore some of the metal rails in the rolled-up state come into contact with the panels, so that these can become hurt.
US-patent nr. 4567931 beskriver sammenhengslede seksjoner av en dør for et varerom til bruk på lastebil, idet seksjonene er utstyrt med hule tetningslister som kommer til anlegg mot hverandre når døren lukkes. US patent no. 4567931 describes interconnected sections of a door for a goods compartment for use on a truck, the sections being equipped with hollow sealing strips that come into contact with each other when the door is closed.
NO-patentsøknad nr. 9003 55 beskriver et sikkerhetsgitter som består av flere plane, gjennomsiktige paneler, som ved hver kant er festet til profiler som utgjør hengsler. For å minske tverrmålet til gitteret i opprullet tilstand har panelene minst bredde ved den enden av gitteret som opprulles først og størst bredde ved den enden som opprulles sist. Dermed bir gitteret komplisert å fremstille. NO patent application no. 9003 55 describes a safety grid which consists of several flat, transparent panels, which are attached at each edge to profiles which form hinges. In order to reduce the transverse dimension of the grid when rolled up, the panels have the smallest width at the end of the grid that is rolled up first and the largest width at the end that is rolled up last. Thus, the grid is complicated to manufacture.
Sikkerhetsgitteret i henhold til den foreliggende oppfinnelse kjennetegnes ved de trekk som fremgår av patentkravet. The safety grid according to the present invention is characterized by the features that appear in the patent claim.
Dermed oppnås at det unngås kjerwirkning eller spenningskonsentrasjon i overgangene mellom broelementenes midtpartier og vulstene. In this way, it is achieved that core effect or stress concentration is avoided in the transitions between the middle parts of the bridge elements and the beads.
Oppfinnelsen skal forklares nærmere i det følgende, under henvisning til de vedføyde tegninger. The invention will be explained in more detail below, with reference to the attached drawings.

Fig. 5 viser et horisontalt snitt gjennom gitteret, i Fig. 5 shows a horizontal section through the grid, i
større målestokk. larger scale.
Fig. 6 viser to broelementer i henhold til oppfinnelsen, Fig. 6 shows two bridge elements according to the invention,
sett fra enden, og montert i et sporprofil. seen from the end, and mounted in a track profile.
Fig. 7 viser et snitt gjennom et sporprofil. Fig. 7 shows a section through a track profile.
Som vist i fig. 1 består et kjent, opprullbart sikkerhetsgitter av flere innbyrdes parallelle sporprofiler 1, som ved endene er ført inn i og kan gli i styreskinner 2, slik at gitteret kan beveges i vertikal retning, opp eller ned, av en ikke vist valse med en rørmotor oventil i sikkerhetsgitteret. As shown in fig. 1, a known roll-up safety grid consists of several mutually parallel track profiles 1, which at the ends are led into and can slide in guide rails 2, so that the grid can be moved in a vertical direction, up or down, by a roller (not shown) with a tubular motor above in the safety grid.
Sporprofilene 1 er oventil og nedentil på den innvendige side utformet med sylinderformede spor 3, som rager i hele sporprofilets lengde. I sporene 3 er det som vist i fig. 6 svingbart lagret flere broelementer 4, som ved endene er utformet med hengseltapper i form av vulster 5. Broelementene 4 forbinder sporprofilene 1, slik at det dannes et sammen-hengende gitter. Broelementene 4 har lik bredde og holdes ved hjelp av sylinderformede avstandsstykker, som er ført inn i sporene 3 i en bestemt innbyrdes avstand. The groove profiles 1 are designed above and below on the inner side with cylindrical grooves 3, which project along the entire length of the groove profile. In the tracks 3, as shown in fig. 6 pivotably stored several bridge elements 4, which at the ends are designed with hinge pins in the form of beads 5. The bridge elements 4 connect the track profiles 1, so that a coherent grid is formed. The bridge elements 4 have the same width and are held by means of cylindrical spacers, which are inserted into the grooves 3 at a certain distance from each other.
Sporprofilene 1 er fremstilt av aluminium, og broelementene 4 kan likeledes være fremstilt av aluminium. Mellom broelementene 4 er det åpninger 6, gjennom hvilke de gjenstander som er utstilt bak sikkerhetsgitteret kan betraktes. The track profiles 1 are made of aluminium, and the bridge elements 4 can likewise be made of aluminium. Between the bridge elements 4 there are openings 6, through which the objects displayed behind the safety grid can be viewed.
De øvrige figurer viser et sikkerhetsgitter i henhold til den foreliggende oppfinnelse. Således viser fig. 3 at det mellom broelementene 4 er innsatt andre broelementer 4', som er fremstilt av et glassklart, gjennomsiktig material, fortrinnsvis av et polykarbonat, og som utfyller åpningene 6 og ligger mot et foregående og etterfølgende broelement 4 langs kanten 7 i hele kantens lengde. Broelementene holdes som vist i fig. 5 i stilling mot hverandre av sylinderformede låsetapper 8. Broelementene 4 og 4' danner således sammen en lukket rad 9 mellom sporprofilene. Denne rad 9 er ved begge ender, slik som vist i fig. 5, ført et stykke inn i styreskinnene 2. Broelementene 4 og 4' har fortrinnsvis samme tverrsnittsprofil, og de kan være fremstilt av samme type material. The other figures show a safety grid according to the present invention. Thus, fig. 3 that other bridge elements 4' are inserted between the bridge elements 4, which are made of a glass-clear, transparent material, preferably of a polycarbonate, and which fill the openings 6 and lie against a preceding and subsequent bridge element 4 along the edge 7 along the entire length of the edge. The bridge elements are held as shown in fig. 5 in position against each other by cylindrical locking pins 8. The bridge elements 4 and 4' thus together form a closed row 9 between the track profiles. This row 9 is at both ends, as shown in fig. 5, guided a bit into the guide rails 2. The bridge elements 4 and 4' preferably have the same cross-sectional profile, and they can be made of the same type of material.
Som vist i fig. 4, kan broelementene 4 ha samme lengde som broelementene 4'. As shown in fig. 4, the bridge elements 4 can have the same length as the bridge elements 4'.
Som vist i fig. 6, er et broelement 4' i henhold til oppfinnelsen ved yttersiden fremstilt med et konvekst midtparti 10 og med konkave ytterpartier 11, som ved overgangen til en vulst 5 har en felles tangent t± med denne. Helningsvinkelen vx til denne tangent er mindre eller lik helningsvinkelen v2 til tangenten t2 til det sirkelformede tverrsnitt i sporene 3 ved sporenes ytterste kant 12. Broelementene 4' har i hele tverrsnittets utstrekning mellom vulstene 5 fortrinnsvis ensartet tykkelse t, som er mindre enn diameteren av en vulst 5. As shown in fig. 6, a bridge element 4' according to the invention is produced on the outer side with a convex middle part 10 and with concave outer parts 11, which at the transition to a bead 5 has a common tangent t± with this. The angle of inclination vx to this tangent is less than or equal to the angle of inclination v2 to the tangent t2 to the circular cross-section in the grooves 3 at the outermost edge 12 of the grooves. The bridge elements 4' throughout the extent of the cross-section between the beads 5 preferably have a uniform thickness t, which is smaller than the diameter of a bead 5.
Et broelement 4' med et slikt tverrsnittsprofil og fremstilt A bridge element 4' with such a cross-sectional profile and produced
av et gjennomsiktig polykarbonat kan ha stor lengde, samtidig med at det er slagfast. of a transparent polycarbonate can have a great length, while being impact-resistant.
