Den foreliggende opfindelse angår et letmetalprofil, specielt beregnet til afviserbjælke i sikkerhedsværn og af den i krav l's indledning angivne art.The present invention relates to a light metal profile, specially designed for safety beam deflector beam and of the kind specified in the preamble of claim 1.

g Det er kendt at fremstille bærende bjælker af letmetal. Disse bjælker får imidlertid en begrænset styrke og bæreevne, når bjælkerne ved stor belastning udsættes for en deformerende ud-bøjning, der kan give anledning til brud i bjælkerne.g Lightweight metal beams are known to be manufactured. However, these beams have a limited strength and bearing capacity when the beams are subjected to a deforming deflection at high loads which may cause the beams to break.

Det er desuden kendt at fremstille strengpressede bjælker af 10 plast eller letmetal med en eller flere armeringsstrenge indlagt. Disses udformning er dog ikke af en sådan art, at de kan bruges som sikkerhedsværn.In addition, it is known to manufacture extruded beams of 10 plastic or light metal with one or more reinforcing strings inlaid. However, these designs are not such that they can be used as a safety guard.

Det er endvidere kendt at fremstille bjælker, i form af afvi-15 serbjælker til sikkerhedsværn, af stål eller beton. Sådanne bjælker er imidlertid vanskelige at håndtere på grund af deres store vægt, hvilket gør bjælkernes montering vanskelig og kostbar. Stålbjælkerne er endvidere kostbare at fremstille og er udsat for rustangreb, såfremt de ikke får en vediigeholdel-20 seskrævende beskyttelsesmaling, og betonbjælkerne er pladskrævende, hvilket er en ulempe, når pladsen er begrænset.Furthermore, it is known to manufacture beams, in the form of deflection beams for security, steel or concrete. However, such beams are difficult to handle due to their heavy weight, which makes mounting the beams difficult and expensive. Furthermore, the steel beams are expensive to manufacture and are subject to rust attacks if they do not receive a maintenance-resistant protective paint and the concrete beams are space-consuming, which is a disadvantage when space is limited.

Det er den foreliggende opfindelses formål at anvise et afsti-vet letmetalprofil, der ved brug i sikkerhedsværn kan defor-25 meres væsentligt uden at briste, således at den kan optage påvirkninger, der kan forekomme i forbindelse med trafikulykker.It is the object of the present invention to provide a stiffened light metal profile which, when used in safety guards, can be significantly deformed without bursting, so that it can absorb stresses that may occur in traffic accidents.

Dette formål tilgodeses ved, at det indledningsvist omtalte letmetalprofil ifølge opfindelsen er ejendommeligt ved det i den kendetegnende del af krav 1 anførte.This object is met by the fact that the initially mentioned light metal profile according to the invention is characterized by the characterizing part of claim 1.

Ved at letmetalsprofilet udformes således, at kernen er anbragt op ad profilets bagside, og at profilets forside har i det mindste en del, der skyder ud frem foran kernen, og har et bueformet tværsnit, der kan deformeres ved stød- eller chock-35 belastning, inden kernen eller kernerne udsættes for maksimal belastning, får profilet egenskaber, der gør det egnet til anvendelse som afviserbjælke i sikkerhedsværn. Dette gælder især såfremt profilets kerne, der kan udgøres af en stål line, ind- 2The light metal profile is formed such that the core is arranged upstream of the back of the profile and that the front of the profile has at least a portion protruding in front of the core and has an arcuate cross-section which can be deformed by shock or shock load. , before the core or cores are subjected to maximum load, the profile acquires properties that make it suitable for use as a deflection bar in security guards. This is especially true if the core of the profile, which can be constituted by a steel line, is 2

lejres i letmetallet ved profilets fremstilling, og derved bliver fast forankret i profilet, hvorved man får et letmetalprofil med meget god styrke og båreevne.is stored in the light metal during the fabrication of the profile, thereby being firmly anchored in the profile, giving a light metal profile with very good strength and bearing capacity.

g En udførelsesform for letmetalprofilet ifølge opfindelsen beskrives nærmere neden for under henvisning til tegningen, der i tværsnit viser en afviserbjælke til brug i sikkerhedsværn.An embodiment of the light metal profile according to the invention is described in more detail below with reference to the drawing, which shows in cross section a bar for use in security protection.

Den i figuren viste afviserbjælke består af et sprøjtestøbt aluminiumprofil, der er udformet med to bueformede kantdele 10 10, 11, der er forbundet ved hjælp af en midterdel 12. Midter delen 12 danner profilets bagside og de bueformede kanter 10, 11 skyder ud fremad fra midterdelen 12 og danner profilets forside. Kantdelene 10, 11 har et i det væsentlige U-formet tværsnit med to ben 10A, 10B henholdsvis 11A, 11B og en bund-15 del 10C henholdsvis 11C. Midterdelen 12 er forbundet med kantdelene 10, 11 ved kanterne på benene 10B henholdsvis 11B.The bar shown in the figure consists of an injection molded aluminum profile formed with two arcuate edge portions 10, 10, 11, which are connected by a central part 12. The middle part 12 forms the back of the profile and the arcuate edges 10, 11 protrude from the front. the center portion 12 forming the front of the profile. The edge portions 10, 11 have a substantially U-shaped cross section with two legs 10A, 10B and 11A, 11B and a bottom 15, 10C and 11C, respectively. The center portion 12 is connected to the edge portions 10, 11 at the edges of the legs 10B and 11B, respectively.

Profilet er ved forbindelsen mellem midterdelen 12 og den ene kantdel 11 udformet med en hul liste 13 med et langsgående hul 20 14, hvori en stålline 15 er anbragt. Hullisten 13 løber langs hele profilet i dennes længderetning og stållinen 15 omsluttes helt af hullisten. Stållinen indlægges i aluminiumprofilet ved sprøjtestøbning af denne således, at materialet i profilet indgriber i fordybningerne mellem stållinens forskellige par-25 ter, hvorved stållinen bliver fast forankret i profilet langs hele dennes længde.The profile is formed at the connection between the middle part 12 and one edge part 11 with a hollow strip 13 with a longitudinal hole 20 14 in which a steel line 15 is arranged. The hole strip 13 runs along the entire profile in its longitudinal direction and the steel line 15 is completely enclosed by the hole strip. The steel wire is inserted into the aluminum profile by injection molding it so that the material in the profile engages in the recesses between the different parts of the steel wire, whereby the steel wire becomes firmly anchored in the profile along its entire length.

De U-formede kantdele 10, ll's forbindelsesben 10B henholdsvis 11B danner en stump vinkel β med den forbindende midterdel 12.The connecting legs 10B and 11B of the U-shaped edge portions 10, 11 respectively form a blunt angle β with the connecting center part 12.

30 Herved opnås, at profilet deformeres ved stød- eller chockbe-lastninger på forsiden, dvs. på de fremskydende kantdele 10, 11. Denne deformering sker ved, at benene 10B, 11B svinges omkring midterdelen 12. Deformer ingen frembringes inden stållinen udsættes for maksimal belastning, og medfører, at et køre-35 tøj, der f.eks. i forbindelse med en trafikulykke kastes imod afviseren med en vis fjedring bremses op af afviserbjælken, således at risikoen for skader på den eller de personer, der kører i køretøjet, reduceres noget. Fjedringen medfører også, 3This results in the profile being deformed by shock or shock loads on the front, ie. on the projecting edge portions 10, 11. This deformation is caused by the legs 10B, 11B being pivoted about the middle portion 12. Deforms are not produced before the steel line is subjected to maximum load, resulting in a vehicle which, e.g. in the event of a traffic accident, the tire is thrown against the repeater with a certain suspension, so that the risk of injury to the person or persons driving the vehicle is reduced somewhat. The suspension also causes, 3

at påvirkningerne på stållinen og på profilets fastgørelsespunkter reduceres, hvilket gør det muligt med en forholdsvis tynd line og tyndere fastgørelsesorganer at opnå en tilstrækkelig styrke for afviserbjælken. En sådan fjedring kan ikke 5 opnås ved hjælp af konventionelle stål- eller betonafviser-bjælker og er yderligere en fordel ved letmetalprofilet ifølge opfindelsen ved brug som afviserbjælke i sikkerhedsværn.that the effects on the steel line and on the points of attachment of the profile are reduced, enabling a relatively thin line and thinner fasteners to obtain a sufficient strength for the deflector beam. Such a suspension cannot be obtained by conventional steel or concrete repellent beams and is a further advantage of the light metal profile according to the invention when used as a deflection beam in security guards.

Ved det på tegningen viste profil er stållinen indlagt i vink-10 len mellem midterdelen 12 og den ene kantdel ll's ben 11B, således at stållinen ligger i en vis afstand fra profilets centerlinie 16. Stållinen får derved større virkning, end om den havde været placeret på profilets centerlinie.In the profile shown in the drawing, the steel line is inserted at the angle between the center part 12 and the leg 11B of one edge part 11, so that the steel line is at a certain distance from the center line of the profile 16. The steel line thus has a greater effect than if it had been placed. on the centerline of the profile.

Ved at stållinen 15 er indlagt i profilets midterdel 12, vil 15 kantdelene 10 og 11 ligge an imod begge sider af stållinen. Derved vil begge kantdelene 10, 11 deformeres på omtrent samme måde ved en forekommende stød- eller chockbelastning, hvilket giver en maksimal fjedringsvirkning for profilet.By inserting the steel line 15 into the center portion 12 of the profile, the edge portions 10 and 11 will abut on both sides of the steel line. Thereby, both edge portions 10, 11 will be deformed in approximately the same way at an occurring shock or shock load, providing a maximum spring action for the profile.

20 Profilet og eventuelt også stållinen fastgøres ved enderne i sikkerhesværnets stolper eller på andre hensigtsmæssige bærere ved hjælp af kendte (ikke viste) fastgørelsesorganer.The profile and possibly also the steel wire are fastened at the ends of the posts of the safety guard or on other suitable carriers by means of known (not shown) fasteners.

Det er muligt i stedet for en stål line at benytte en anden 25 type kerne, f.eks. en stav, der kan have et vilkårligt tværsnit. Kernen indlægges i profilet enten ved dennes fremstilling eller senere, hvorved den indskydes i den i profilet udformede hulliste og fastgøres eventuelt til profilet i et antal punkter. I stedet for en eneste kerne kan to eller flere 3Q kerner indlægges i profilet. Såfremt man be-nytter to kerner, placeres disse hensigtsmæssigt i profilets yderkanter, eftersom kernernes virkning øger med afstanden fra profilets centerlinie. Profilet kan også udformes på anden må-de end med to bueformede kantdele, f.eks. med en eneste bueformet del, der 35 så kan strække sig frem fra den eller de i profilet anbragte kerner. Væsentlig ved profilets udformning for sikkerhedsværn er imidlertid, at profilet deformeres ved stød-eller chockbe-lastninger, således at den størst mulige fjedringsvirkning opnås ved belastning.It is possible to use another type of core instead of a steel line, e.g. a rod that can have any cross section. The core is inserted into the profile either by its manufacture or later, whereby it is inserted into the hole molding formed in the profile and possibly attached to the profile in a number of points. Instead of a single core, two or more 3Q cores can be embedded in the profile. If two cores are used, these are conveniently placed at the outer edges of the profile as the effect of the cores increases with the distance from the center line of the profile. The profile can also be designed in a different way than with two curved edge parts, e.g. with a single arcuate portion which may then extend from the core (s) located in the profile. However, an essential part of the profile design for safety protection is that the profile is deformed by shock or shock loads, so that the greatest possible springing effect is achieved by load.
