Den foreliggende opfindelse angår en båndlås omfattende et i tværsnit U-formet legeme og en mellem legemets flanger lejret klap, der kan svinges om en tværakse for fastklemning af båndet mellem klappen og legemets krop ved nedfældning af klappen mod kroppen.The present invention relates to a belt lock comprising a cross-section U-shaped body and a flap located between the flanges of the body, which can be pivoted about a transverse axis for clamping the band between the flap and the body of the body by folding the flap against the body.

5 Låse af denne art har været kendt i lang tid og er i stort omfang blevet benyttet som sikkerhedsbælter i flyvemaskiner og biler. Klappen er i denne forbindelse fjederbelastet til sin nedslåede stilling, dvs. låsestillingen eller indgrebs-10 stillingen, og når båndet skal løsnes, må klappen således løftes mod fjederbelastningens virkning. Dette giver fuld tilstrækkelig sikkerhed mod, at låsen utilsigtet åbnes ved de anvendelser, der tidligere er forekommet i forbindelse med lås af den her omtalte art, men i den seneste tid har 15 o man fundet en ny anvendelse for lasen, hvor man synes, at udførelsesformen med en fjederbelastet klap ikke giver en betryggende sikkerhed, nemlig når låsen er anbragt på bånd, der anvendes til tøjring af dyr. Når låsen benyttes til dette formål, kan man ikke stole på den sikkerhed mod utilsigtet 20 åbning af låsen, som fjederbelastningen af klappen medfører.5 Locks of this kind have been known for a long time and have been widely used as safety belts in airplanes and cars. In this regard, the flap is spring-loaded to its downturned position, ie. thus, when the belt is to be loosened, the flap must be lifted against the action of the spring load. This provides full sufficient assurance that the lock will be unintentionally opened by the applications that have previously occurred in the case of locks of this type, but in recent times a new use has been found for the lock, where it appears that the spring-loaded flap embodiment does not provide reassuring security, namely when the latch is placed on ribbons used for tethering animals. When the lock is used for this purpose, the safety against unintentional opening of the lock caused by the spring load of the flap cannot be relied upon.

Det har vist sig, at låsen let går op, når dyret klør sig eller gnider sig mod en eller anden genstand, eller når dyrene angriber hinanden. Der kræves derfor en eller anden form for spærreanordning, der giver en større sikkerhed mod, at 25 låsen utilsigtet åbnes, men samtidigt stilles der krav om, at indarbejdningen af en sådan spærreanordning i låsen ikke medfører en væsentlig fordyrelse af låsen, der allerede i den nuværende udførelsesform er underkastet et kraftigt pristryk.It has been found that the lock easily opens when the animal itches or rubs against some object or when the animals attack each other. Therefore, some form of locking device is required which provides a greater security against unintentionally opening the lock, but at the same time it is required that the incorporation of such locking device into the lock does not result in a substantial costing of the lock already in the lock. current embodiment is subject to high price pressure.

Den på tegningerne viste lås omfatter et i tværsnit U-formet legeme 10 af stålplade med krop 11 og flanger 12. Kroppen er ved låsens ene ende udformet med en slids 13 for fastgørelse af 30 et band 14 og er ved den anden ende bukket op til dannelse af en vederlagsflade 15 med en vulst.The lock shown in the drawings comprises a cross-sectional U-shaped body 10 of steel plate with body 11 and flanges 12. The body is formed at one end of the lock with a slot 13 for attaching a band 14 and is bent at the other end to forming a reclining surface 15 with a bead.

En klap 16 er udformet med en fortykket del 17, hvorigennem der er ført en nitte 18, ved hjælp af hvilken klappen er sving-3 5 bart lejret mellem flangerne 12, hvorved klappen har en sådan bredde, at den kan svinges ned mellem flangerne mod kroppegA flap 16 is formed with a thickened portion 17 through which a rivet 18 is guided, by means of which the flap is pivotably supported between the flanges 12, the flap having a width such that it can be swung down between the flanges towards kroppeg

3 11. Den fortykkede del 17 er udformet med riller 19 på den mod kroppen 11 vendende side, og ved nedslåning af klappen mod kroppen kommer disse riller til at befinde sig i området for vederlagsfladen 15 og tæt op mod denne for fastklemning af et bånd 20 mellem den fortykkede del af klappen og veder- ® lagsfladen således, som vist i fig. 9 til 11. Jo længere ned med kroppen klappen svinges, desto hårdere klemmes båndet 20 fast i låsen. Båndene 14 og 20 kan naturligvis udgøres af endepartierne af et og samme bånd, f.eks. et bånd som er anbragt som halsbånd på et dyr. Når båndene trækkes i modsat retning, vil dette medføre, at indgrebet i låsen forstærkes, da klappen så bliver svunget mod kroppen. Det rillede parti af den fortykkede del 17 bør have en sådan vinkelstilling, at afstanden mellem rillerne 19 og vederlagsfladen 15 bliver mindre,jo længere ned mod kroppen klappen svinges med den 15 følge, at rillerne presses hårdere mod eller længere ind i båndet.11. The thickened portion 17 is formed with grooves 19 on the side facing the body 11, and when the flap is hit against the body, these grooves come into the region of the reclining surface 15 and close to it for clamping of a belt 20 between the thickened portion of the flap and the bed surface thus, as shown in FIG. 9 to 11. The further down with the body flap swings, the harder the belt 20 is clamped in the lock. The bands 14 and 20 can, of course, be constituted by the end portions of one and the same band, e.g. a leash which is placed as a collar on an animal. When the straps are pulled in the opposite direction, this will cause the locking mechanism to be tightened as the flap is then pivoted towards the body. The grooved portion of the thickened portion 17 should have an angular position such that the distance between the grooves 19 and the reclining surface 15 becomes smaller, the further down towards the body the flap is pivoted with the result that the grooves are pressed harder against or further into the belt.

Udførelsesformen og funktionen for låsen er indtil nu den samme som for kendte låse af den angivne art.The embodiment and function of the lock is so far the same as for known locks of the specified type.

Knappen 16 er på sin underside udformet med en skuffeformet liste 21 for montering af den i låsen ifølge opfindelsen indgående spærreanordning for klappen. Denne liste, der har en rektangulær tværsnitsform, tjener til at optage og styre 25 to tappe 22, der er indført i listen fra modsatte ender og er udformet med et fladt hoved 23, se fig. 6 og 7. I de mod hinanden vendende ender danner tappene et cylindrisk fremspring 24, og en skrueformet trykfjeder 25 er med sine ender indført på disse fremspring for at belaste tappene i retning bort 30 fra hinanden. For at forhindre at tappene derved skydes ud af listen, er et par tværstifter 26 fastgjort i tappene og optages i slidser 27 i listen.Begge slidser strækker sig i dennes længderetning og således begrænses den mulige forskydning af tappene i listens længderetning.The button 16 is formed on its underside with a drawer-shaped strip 21 for mounting the flap locking device included in the invention. This list, having a rectangular cross-sectional shape, serves to receive and guide two pins 22 inserted in the list from opposite ends and formed with a flat head 23, see FIG. 6 and 7. At the opposite ends, the pins form a cylindrical projection 24, and a helical compression spring 25 is inserted at these ends with these ends to load the pins in the direction away from each other 30. In order to prevent the pins from being ejected from the frame, a pair of cross pins 26 are secured to the pins and accommodated in slots 27 in the frame. Both slots extend in their longitudinal direction, thus limiting the possible displacement of the pins in the longitudinal direction of the frame.

Når tappene holdes i de viste ydre stillinger under påvirkning af fjederen 25, befinder disse kamflader sig midt over kanterne på flangerne 12, og de er så skråt stillet, at de ved anpresning af klappen med kroppen under anslag af kamfladerne mod flange-5 .kanterne vil tvinge tappene 22 indad i listen 21 mod fjederens 25 virkning.formed with a bevel or cam surface 28. When the pins are held in the outer positions shown under the action of the spring 25, these cam faces are located midway over the edges of the flanges 12 and are so inclined that when pressing the flap with the body under impact of the cam faces toward the flange-5 edges will force the pins 22 inwardly of the strip 21 against the action of the spring 25.

Mel Lem kc.mf laderne 2.8 og hovedet 23 er hver tap 22 udformet med en hals 29, der er smallere end tappen i øvrigt. Hver 10 flange 12 på legemet 10 har ud for den tilsvarende tap 22 en slids 30 med et smallere mundingsparti 31, der har en sådan bredde, at halsen 29 kan passere derigennem, men derimod ikke tappen i øvrigt, der imidlertid kan optages i slidsen 30 i øvrigt, hvor denne er bredere. Slidsén afsluttes ved 15 sin indre ende eller bund med et smallere bundparti 32, der har samme bredde som mundingspartiet 31. Bundpartiet 32 slutter sig til slidsen 30 i øvrigt ved to ansatse 33.Flour lem cc.mf chargers 2.8 and head 23 are each tab 22 formed with a neck 29 narrower than the pin overall. Each 10 flange 12 of the body 10 has, next to the corresponding pin 22, a slot 30 with a narrower mouth portion 31 having a width such that the neck 29 can pass therethrough, but not the other pin, which however can be received in the slot 30 moreover, where this is wider. The slit is terminated at its inner end or bottom by a narrower bottom portion 32 having the same width as the mouth portion 31. The bottom portion 32 joins the slot 30 otherwise by two abutments 33.

Funktionen af den beskrevne lås med den for opfindelsen spe-20 - - - cielle låseanordning beskrives under henvisning til fig. 8-11.The operation of the described lock with the special locking device of the invention is described with reference to FIG. 8-11.

Når låsen er i den åbne stilling vist i fig. 8 indføres båndet 20 fra venstre mellem den fortykkede del 17 af klappen 16 og vederlagsfladen 15, hvorefter klappen slås ned mod krop-25 . .When the lock is in the open position shown in FIG. 8, the strip 20 is inserted from the left between the thickened portion 17 of the flap 16 and the reclining surface 15, after which the flap is lowered against body-25. .

pen 11. Derved kommer kamfladerne 28 pa tappene 22 til at ligge an mod kamfladerne på flangerne 12, hvorved fortsat nedslåning af klappen standses, såfremt man ikke trykker tappene ind mod fjederens 25 virkning eller øger trykket på klappen således, at tappene kamskiveagtigt trykkes mod hinanden 30 mod fjederens virkning, og halsen 29 på hver tap kommer ud for mundingspartiet 31 og kan passere igennem dette, for at klappen skal nå stillingen vist i fig. 9. Nu kan tappene skydes ud i slidsen 30 med det bredere parti under fjederens 25 virkning, og dermed hindres klappen fra at svinge op fra 3 5 den nedslåede stilling til åbne stilling vist i fig. 8, da tappenes bredere parti ikke kan passere gennem slidsens mundings-pin 11. This causes the cam faces 28 of the pins 22 to abut against the cam faces of the flanges 12, thereby continuing to shut down the flap if the pins are not pressed against the action of the spring 25 or to increase the pressure of the flap so that the pins cam-like are pressed against each other. 30 against the action of the spring, and the neck 29 of each pin exits the orifice portion 31 and can pass therethrough for the flap to reach the position shown in FIG. 9. Now the pins can be pushed out into the slot 30 with the wider portion under the action of the spring 25, thus preventing the flap from swinging up from the knocked-down position to the open position shown in FIG. 8, since the wider portion of the pins cannot pass through the orifice of the slot.
