Description

i 148212 5 Opfindelsen angår et låsbart spænde for bånd eller remme af den i krav 1's indledning angivne art.The invention relates to a lockable buckle for straps or straps of the kind specified in the preamble of claim 1.

Spænder af denne art, hvor låsevirkningen udøves ved friktion, og hvor de låsende dele kan føres 10 mellem en låsestilling og en åben stilling eller fristilling af et manuelt påvirkeligt manøvreringsorgan er kendte, fx til anvendelse på sikkerhedsbælter. Fra US-patentbeskrivelserne nr. 2.511.579 og nr. 3.152.374 kendes sådanne låsbare spænder af 15 den nævnte art, hvor spændet fastgøres i den ene ende af et bånd eller en rem, medens båndets anden ende føres gennem en åbning i spændet og danner en løbedel, og hvor båndet kan klemmes fast et vilkårligt sted af et låseorgan. Låseorganet er ofte 20 udformet således, at det er selvlåsende, d.v.s.Buckles of this kind in which the locking action is exerted by friction and where the locking parts can be guided between a locking position and an open position or release of a manually actuated actuator are known, for example, for use on seat belts. From U.S. Patent Specifications Nos. 2,511,579 and 3,152,374, such lockable buckles of the said kind are known in which the strap is secured to one end of a strap or strap, while the other end of the strap is passed through an opening in the strap and forming a running part and where the belt can be clamped at any location by a locking means. The locking member is often designed to be self-locking, i.e.

at låsekraften forøgs, når båndet udsættes for belastning, idet den gennem spændet gående bånddel udsættes for en kilevirkning af låseorganet. Sådanne spænder er konstrueret til at anvendes på bånd af 25 naturlige materialer af fx leeder, bomuld, hamp og lignende materialer, der kan være vævede. Sådanne materialer har en rimelig trækstyrke og kan tåle store deformationer, fx fra låseorganer med kæber eller tænder, der kan bide fast i materialet og 30 derved give stor friktion. Sådanne naturlige materialer har dog visse uheldige egenskaber, som fx at de ældes, hvorved trækstyrken bliver mindre, hvilket er uheldigt fx ved sikkerhedsbælter.that the locking force is increased when the belt is subjected to stress, the exposed belt member being subjected to a wedge effect by the locking means. Such buckles are designed to be used on strips of 25 natural materials of, for example, leather, cotton, hemp and similar woven materials. Such materials have a reasonable tensile strength and can withstand large deformations, for example, from locking means with jaws or teeth that can bite into the material and thereby provide high friction. However, such natural materials have certain unfortunate properties, such as their aging, thereby reducing tensile strength, which is unfortunate, for example, in seat belts.

2 148212 1 Man ønsker derfor at anvende bånd af syntetiske materialer, fx af amid-plast eller polyesterplast, idet sådanne materialer har meget stor trækstyrke, der forbliver konstant. Materialer af denne art 5 har god enkelte ulemper, idet de har en lav overfladefriktion og derfor er meget glatte og desuden tåler de dårligt de deformationer, som de kendte båndspænder påfører, er båndspændet udført, så låseorganet påfører båndet lokale fastklemninger, fx 10 fordi det er udformet med tænder som i de foran omtalte USA-patentbeskrivelser, kan det syntetiske materiale deformeres og give efter, således at friktionen bliver for lille og båndet kryber i spændet, når båndet belastes.Therefore, it is desired to use bands of synthetic materials, for example, of amide-plastic or polyester-plastic, since such materials have very high tensile strength which remains constant. Materials of this kind 5 have good single disadvantages in that they have a low surface friction and therefore are very smooth and, in addition, they can withstand the deformations that the known belt buckles are applied to the belt buckle, so that the locking means applies to the belt local clamps, e.g. is designed with teeth as in the aforementioned United States Patent Specifications, the synthetic material may be deformed and yield, so that the friction becomes too small and the belt creeps into the buckle when the belt is loaded.

Formålet med opfindelsen er at angive et låsbart spænde af den i krav l's indledning angivne art, men som er anvendeligt til bånd eller remme af syntetiske materialer.The object of the invention is to provide a lockable buckle of the kind specified in the preamble of claim 1, but which is applicable to straps or straps of synthetic materials.

2020

Dette opnås ved at udforme spændet som angivet i krav 1!s kendetegnende del.This is accomplished by designing the clamp as set forth in claim 1!

Herved bliver det muligt at udnytte den store og 25 stabile trækstyrke ved plastbånd, idet de kan fastlåses sikkert uden fare for at glide i spændet, og uden at der sker ødelæggende plastiske deformationer på båndet, fordi kombinationen af, at båndet presses mod indersiden af huset af glideorganet 30 og udøver en vis selvlåsende virkning og kamvirkningen ved glideorganets modsatte ende, tilsammen frembringer en jævnt fordelt, men fuldstændig låsende virkning. Den låsende virkning er således opnået uden tænder eller andre former for friktionsgivende 148212 3 1 deformeringer på låseorganet, således at låsnin gen sker jævnt fordelt over hele glideorganet og den her overfor liggende del af huset.This makes it possible to utilize the large and stable tensile strength of plastic strips, since they can be securely locked without danger of slipping in the strap and without damaging plastic deformations on the strip because the combination of the strip being pressed against the inside of the housing of the slider 30 and exert some self-locking action and the cam action at the opposite end of the slider together produces an evenly distributed but completely locking action. The locking effect is thus obtained without teeth or other types of frictional deformations on the locking member, so that the locking is evenly distributed over the entire sliding member and the opposite part of the housing.

Huset 10, fig. 1, har i hovedsagen form af en opadtil åben U-skinne med en krop eller bund 12 og to opadragende flanger eller gavle 14. Ved enderne af huset er anbragt par af indadbøjede ører 16 og 30 18 ved overkanten af gavlene 14, hvor ørerne 16 ved husets i figurens venstre ende dels er noget mindre og kortere end ørerne 18 ved husets højre ende, dels rettet således, at deres undersider danner en lille vinkel med husets bund 12. I den sidstnævnte 148212 5 1 findes der to åbninger/ hvoraf en første åbning 22 har form af et spor, der strækker sig vinkelret på husets længderetning over den største del af husets bund, nser den ende, hvor ørerne 18 befin-5 der sig. En anden åbning 24 er beliggende et stykke længere inde i huset og strækker sig ligeledes vinkelret på husets længderetning og langs størstedelen af bredden af bunden 12. Åbningen 24 er med fordel frembragt ved, at en flig 26 er brudt 10 op af bunden 12, og fligen er udformet med afrundet tværsnit, som det fremgår af fig. 1. De to åbninger 22 og 24 har en længde svarende til bredden af det til spændet bestemte bånd, som det skal beskrives nedenfor. I husets opragende vægge eller gavle 14 15 er der udformet midt for hinanden beliggende lejeåbninger 28 fog akselen 20, fig. 2.The housing 10, fig. 1, is generally in the form of an upwardly open U-rail having a body or bottom 12 and two upwardly extending flanges or gables 14. At the ends of the housing are placed pairs of inwardly bent ears 16 and 30 at the upper edge of the gables 14, the ears 16 at the left-hand end of the housing is somewhat smaller and shorter than the ears 18 at the right-hand end of the housing, and partly so that their undersides form a small angle with the bottom of the housing 12. In the latter there are two openings / of which a first opening 22 is in the form of a groove extending perpendicular to the longitudinal direction of the housing over the greater part of the bottom of the housing, reaching the end at which the ears 18 are located. Another opening 24 is located a little further inside the housing and also extends perpendicularly to the longitudinal direction of the housing and along most of the width of the base 12. The opening 24 is advantageously provided by a tab 26 being broken up by the bottom 12, and the tab is formed with a rounded cross-section, as shown in FIG. 1. The two apertures 22 and 24 have a length corresponding to the width of the strap-determined band, as will be described below. In the upright walls or ends 14 15 of the housing, central bearing openings 28 along the shaft 20 are formed, FIG. 2nd

Fig. la og lb anskueliggør modifikationer af huset i fig. 1. I fig. la er således bundpartiet 12' af 20 huset 10' forlænget noget til venstre, set på tegningen, hvorved en tværgående åbning eller et spor 25 er udformet i dette forlængede bundparti, fortrinsvis ved at en flig 27 er presset op af partiet, som tydeligt vist i fig. la. Endvidere har sporet 25 25 en længde svarende til bredden af det til sporet bestemte bånd eller remmen. Ifølge fig. lb er huset 10'' udstyret med et krummet bundparti 121', der enten kan være kontinuerligt bøjet, eller som vist i fig. Ib, sammensat af to i hovedsagen rette dele, 30 der ligger under en vis vinkel med hinanden.FIG. 1a and 1b illustrate modifications to the housing of FIG. 1. In FIG. 1a, the bottom portion 12 'of the housing 10' is thus slightly extended to the left, as seen in the drawing, whereby a transverse opening or groove 25 is formed in this extended bottom portion, preferably by a tab 27 being pushed up by the portion, as clearly shown. in FIG. la. Further, the groove 25 25 has a length corresponding to the width of the strap or strap provided for the groove. According to FIG. 1b, the housing 10 '' is provided with a curved bottom portion 121 'which can either be continuously bent or as shown in FIG. Ib, composed of two generally straight parts 30 lying at a certain angle to each other.

Det bevægelige glideorgan 30, fig. 3, har også i hovedsagen U-formet tværsnit og består af et bundparti 32 med opragende gavle 34, hvis overkanter er 6 UD212 1 udformet med i hovedsagen samme hældning som husets 10 ovenfor nævnte ører 16. Bundpartiets ifølge figuren højre ende er forlænget og forhøjet til en bueformet tunge 36, medens den venstre ende ligeledes 5 er forlænget, men nedadbøjet til en kortere tunge 41. Mellem gavlene 34 findes en åbning 38 i bunden 32, ved at en flig 40 er brudt op gennem bunden mellem gavlene, som vist tydeligt i fig. 3. Den udvendige bredde af glideorganet 3 0 over gavlene 10 34 er således afpasset, at glideorganet med let løbende pasning kan optages mellem husets 10 opragen-de gavle 14, og længden af åbningen eller sporet 38, d.v.s. den indvendige afstand mellem gavlene 34, svarer til bredden af det for spændet bestemte 15 bånd.The movable slider 30, FIG. 3, also has a generally U-shaped cross-section and consists of a bottom portion 32 with projecting gables 34, the upper edges of which are 6 UD212 1 formed with substantially the same inclination as the ears of the housing 10 mentioned above 16. The bottom end of the right end of the figure is extended and raised to an arcuate tongue 36, while the left end is also extended 5, but bent downwards to a shorter tongue 41. Between the gables 34 is an opening 38 in the bottom 32 by a tab 40 being broken through the bottom between the gables, as clearly shown. in FIG. 3. The outside width of the slider 30 over the gables 10 34 is adapted so that the slider with easy running fit can be accommodated between the raised gables 14 of the housing 10 and the length of the opening or groove 38, i.e. the internal distance between the gables 34 corresponds to the width of the strap for the tension.

Vedrørende låsearmen 50, fig. 4, består denne af et i hovedsagen cylindrisk kamparti 52, til hvis modstående ender der er fastgjort modstående side-20 stykker 56. De fri ender af sidstnævnte er forbundet ved en bro 58, der strækker sig langs sidestykkernes overkanter, som det fremgår af fig. 4, og fortsætter udad i form af et gribeøre eller håndtag 60, der er adskilt fra broen i øvrigt ved fra hver side 25 udgående udsparinger eller indskæringer 62. det cylindriske kamparti 51 er udformet med en gennemgående, ekscentrisk beliggende lejeåbning 54 indrettet til glidbart at optage ovennævnte aksel 20. Længden af kampartiet 52, d.v.s. den udvendige bredde af 30 låsearmen 50 som helhed, er således afpasset at armen med ubetydeligt spillerum passer ind mellem husets 10 opadragende gavle 14.Regarding the locking arm 50, FIG. 4, it consists of a generally cylindrical match portion 52, to the opposite ends of which are attached opposed side pieces 20. The free ends of the latter are joined by a bridge 58 extending along the upper edges of the side pieces, as shown in FIG. . 4, and extends outwardly in the form of a gripping ear or handle 60, which is separated from the bridge otherwise by recesses or notches 62 extending from each side. The cylindrical bore portion 51 is formed with a continuous, eccentrically located bearing opening 54 arranged for slidably take up the aforementioned shaft 20. The length of the match portion 52, ie the outer width of the locking arm 50 as a whole is adapted such that the arm with negligible clearance fits between the upwardly facing end 14 of the housing 10.

Spændets sammensætning og dets samvirkning med tilhø- U8212 7 1 rende bånd eller rem skal nu beskrives under henvisning til fig. 5-7. Glideorganet 30 indlægges mellem husets 10 gavle 14 således, at det befinder sig i husets ifølge figurerne venstre del og med sin 5 venstre ende liggende under husets ører 16. Låsearmen 50 indlægges mellem husgavlene 14 med sin lejeåbning 54 sammenfaldende med lejeåbningerne 24 i huset.The composition of the buckle and its interaction with the associated belt or strap will now be described with reference to FIG. 5-7. The slider 30 is inserted between the gables 14 of the housing 10 so that it is in the left part of the housing according to the figures and with its 5 left end lying under the ears of the housing 16. The locking arm 50 is inserted between the housing gables 14 with its bearing opening 54 coinciding with the bearing openings 24 in the housing.

Akselen 20 indføres i åbningerne og fikseres på egnet, ikke nærmere vist måde i stilling. Herved 10 vil låsearmens 50 cylindriske kamparti 52 optages indenfor glideorganets 30 bueformede tunge 36, hvor dennes indvendige krumning er således, at tungen tilslutter sig efter kappefladen af det cylindriske kamparti 52, som vist i fig. 5. Glideorganets 30 15 opadragende gavle 34 er som vist udformede med højre siderne hældende, hvorved det cylindriske kamparti 52 vil optages mellem den nedre del 35 af disse hældende sider og indersiden af den opadbøjede tunge 36. Når akseltappen 20 fjernes kan låsearmen 50 20 med sit kamparti 52 løftes ud af glideorganet i den med pilen A markerede retning, eventuelt efter først at være bøjet bort fra den øvre ende eller spidsen af tungen 36.The shaft 20 is inserted into the openings and fixed in a suitable position, not shown in detail. Hereby, the cylindrical collar portion 52 of the locking arm 50 will be accommodated within the arcuate tongue 36 of the slider 30, the inner curvature thereof being such that the tongue joins the casing surface of the cylindrical collar portion 52, as shown in FIG. 5. The upwardly facing end 34 of the slider 30 is inclined as shown with the right sides, whereby the cylindrical match portion 52 will be accommodated between the lower portion 35 of these inclined sides and the inside of the upwardly bent tongue 36. When the shaft 20 is removed, the locking arm 50 20 can be removed with its combat portion 52 is lifted out of the slider in the direction marked by arrow A, optionally after first bending away from the upper end or tip of the tongue 36.

25 Som vist er kampartiets 52 ekscentriske lejring således, at når låsearmen 50 svinges i hovedsagen lige op som vist i fig. 5 vil kampartiet bevæge glideorganet 30 noget til højre og opad i forhold til en stilling, i hvilken låsearmen er svinget 30 med-urs ifølge tegningerne til en i hovedsagen vandret stilling, som vist i fig. 6. I sidstnævnte stilling er glideorganet 30 således af det ekscentriske kamparti 52 presset stort set nedad, og det indgriber herved låsende med den samvirkende rem, som det 148212 8 1 skal beskrives.25 As shown, the eccentric bearing of the match 52 is such that when the locking arm 50 is pivoted substantially straight up as shown in FIG. 5, the combat portion will move the slider 30 slightly to the right and upwardly with respect to a position in which the locking arm is pivoted 30 in accordance with the drawings to a substantially horizontal position, as shown in FIG. 6. Thus, in the latter position, the slider 30 is pressed downwardly by the eccentric combat portion 52, thereby engaging the locking belt with the cooperating belt which it is to be described.

I princippet kan remspændet ifølge opfindelsen anvendes til at sammenkoble to adskilte remme, hvorved 5 den ene rem er fast forankret i spændet, medens den anden er anbragt løbende gennem dette. Det sædvanligste tilfælde er imidlertid, at spændet anvendes med en sammenhængende rem, hvor dennes ene endeparti 70 danner en forankringsdel, der forbindes fast 10 med spændet, se fig. 5 og 6. Remdelen 70 forenes således med den højre del af husets 10 bundparti 12, hvorhos denne sammenkobling kan skal på vilkårlig måde, fx ved at remenden nittes fast i bunden eller føres gennem åbningen 22 og nittes eller syes fast 15 til sig selv i et øje, der griber om det af åbningen 22 adskilte parti af husets bund 12. Imidlertid kan remenden med stor fordel trædes et par gange mellem åbningerne 22 og 24, så at remmen danner dobbelte omslag, fx som vist i fig. 5 og 6. Herved 20 trædes den fri remende 70 først oppefra ned gennem åbningen 24, derefter rundt om enden af bundpartiet 12, ned gennem åbningen 22 og tilbage til åbningen 24 for denne gang at trædes opad gennem denne åbning, så at den fri remende havner lige udenfor huset 25 under den fra dette udgående del af remmen 70. Når remmen trækkes til, fås den form, der er vist i fig. 5 og 6, og den giver remmen, en urokkelig fast forankring i spændet. Dette arrangement har givetvis den store fordel, at man bliver helt uafhængig af 30 syning og nitning. Remmen kan afskæres i vilkårlig ønsket længde, og hvis der er tale om et plastbånd eller en plastrem kan trådene i den afklippede remene smeltes sammen og forsegles med en tændstik eller anden åben flamme. Ved som antydet at træde remmen 148212 9 1 nogle gange mellem åbningerne 22 og 24 fås hurtigt en fast og helt sikker kobling til spændets hus eller faste del 10.In principle, the belt buckle according to the invention can be used to couple two separate belts, whereby one belt is firmly anchored to the buckle while the other is arranged continuously through it. The most common case, however, is that the strap is used with a continuous strap, one end portion 70 of which forms an anchoring member which is fixedly fixed 10 to the strap, see fig. 5 and 6. The belt part 70 is thus joined to the right part of the bottom portion 12 of the housing 10, which this coupling may be in any way, for example by riveting the belt end to the bottom or passing through the opening 22 and riveting or stitching 15 to itself. an eye gripping the portion separated by the aperture 22 from the bottom of the housing 12. However, the belt end can be advantageously threaded a few times between the apertures 22 and 24 so that the strap forms double covers, e.g., as shown in FIG. 5 and 6. Hereby 20, the free strap 70 is first stepped from the top down through the opening 24, then around the end of the bottom portion 12, down through the opening 22 and back to the opening 24 to be threaded upwards through this opening so that the free strap ends just outside the housing 25 below it from this portion of belt 70. When the belt is pulled, the shape shown in FIG. 5 and 6, and it gives the strap an unshakable firm anchor in the strap. This arrangement obviously has the great advantage of being completely independent of 30 sewing and riveting. The belt can be cut to any desired length, and in the case of a plastic belt or a plastic belt, the threads of the cut belt can be fused together and sealed with a match or other open flame. As indicated by the tensioning of the belt 1482 sometimes between the openings 22 and 24, a fast and completely secure coupling to the housing or fixed part 10 of the belt is quickly obtained.

5 Remmens anden, frie ende 75 trædes ind gennem spændets modsatte ende, som vist i fig. 5, d.v.s. ovenfra ned gennem åbningen 38 i glideorganets 30 bund 32 og videre ind mellem glideorganets underside og oversiden af husets bund 12 for senere at fortsætte 10 op omkring ydersiden af glideorganets bøjede tunge 36. Det er nødvendigt at remmen føres ned gennem åbningen 38. Den må således ikke rage direkte ind under glideorganet 30. Til dette formål er glideorganets bundparti forlænget med den nedadbøjede. tunge 15 41, der således forhindrer en sådan fejltrædning af båndet. Remdelen 75 føres derefter passende videre ud mellem låsearmens 50 sidestykker 56 og. gennem den åbning der dannes mellem låsearmens bro 58 og kamparti 52, som vist med fuldt optrukne linier 20 i fig. 5. Remmen kan imidlertid, hvis det er egnet i visse tilfælde, fortsætte lige ud, som det er markeret med punkterede linier ved 75' i fig. 5 (dog skal remmen før den efterfølgende låsning trædes gennem den nævnte åbning mellem broen 58 og kampar-25 tiet 52, som det vil fremgå af det følgende). Remmen kan nu strækkes, fx efter at den er anbragt omkring en genstand, om hvilken der skal spændes, ved at dens løbedel 75 trækkes gennem spændet, hvilket således nu befinder sig i sin i fig. 5 viste åbne 30 stilling, i hvilken remmen kan løbe frit mellem glideorganets 30 underside og oversiden af husets 10 bund 12.5 The second free end 75 of the belt is retracted through the opposite end of the strap, as shown in FIG. 5, i.e. from above down through the opening 38 in the bottom 32 of the slider 30 and further in between the underside of the slider and the upper side of the bottom 12 of the housing to later continue 10 up around the outside of the bent tongue of the slider 36. It is necessary that the strap be passed down through the opening 38. do not project directly under the slider 30. For this purpose, the bottom portion of the slider is extended with the downwardly bent. tongue 15 41 thus preventing such a failure of the belt. Conveniently, the belt portion 75 is further extended between the side pieces 56 and of the locking arm 50. through the aperture formed between the locking arm's bridge 58 and combat portion 52, as shown by fully drawn lines 20 in FIG. 5. However, the belt, if suitable in certain cases, may continue straight out, as is marked by dashed lines at 75 'in FIG. 5 (however, the belt must be threaded through the said opening between the bridge 58 and the combat device 52 before the subsequent locking, as will become apparent from the following). The belt can now be stretched, for example, after it is placed around an object about which to be tightened, by pulling its running part 75 through the tension, which is thus now in its position in FIG. 5, in which the belt can run freely between the underside of the slider 30 and the upper side of the bottom 12 of the housing 10.

148212 10 1 Når remmen er trukket så kraftigt som muligt, låses den fast i spændet ved at låsearmen 50 svinges ned til sin i fig. 6 viste låsestilling. Herved presser kampartiet 52 ved excentervirkning glideorganet 5 30 nedad til indgreb med remmen, der klemmes fast mod husets bund 12. Samtidig presses glideorganets venstre ende nedad af spændingen P i remmen 75, se fig. 6, på grund af, at den afbøjes nedad gennem åbningen 38 i glideorganet. Remspændingen får herved 10 en nedadrettet ko'mposant P', der virker mod glideor-' ganets venstre ende med det resultat, at påtrykningskraften eller klemmekraften på remmen fordeles mere ensartet langs glideorganet. Herved kan også overkanterne af glideorganets gavle 34 med en vis kilevirk-15 ning gribe ind under husets venstre skrånende ører ved at det ekscentriske kamparti 52 ved låsningen også forskyder glideorganet 30 noget mod venstre.When the strap is pulled as tightly as possible, it is locked into the buckle by pivoting the locking arm 50 down to the one shown in FIG. 6. In this way the fighting part 52, by eccentric action, presses the slider 5 downwards to engage the strap which is clamped against the bottom of the housing 12. At the same time, the left end of the slider is pressed downwards by the tension P in the belt 75, see fig. 6, because it is deflected downwardly through the opening 38 of the slider. The belt tension hereby causes a downwardly directed component P 'which acts against the left end of the slider, with the result that the pressing force or clamping force on the belt is distributed more uniformly along the slider. Hereby, the upper edges of the slider member's gables 34 can also, with a certain wedge action, engage under the left sloping ears of the housing by the eccentric match portion 52 at the locking also displacing the slider 30 slightly to the left.

Ved dette indgreb mellem ørerne 16 og glideorganet vil dettes venstre ende yderligere presses nedad 20 til påpresning mod remmen. Hvis det ønskes, og for at sikre glideorganets nævnte sideforskydning, kan gavlenes 34 nær kampartiet 52 liggende kanter 35, se fig. 5, indrettes til delvis at indgribe med kampartiet, så at glideorganet tvangsmæssigt forsky-25 des mod venstre, set på tegningen, når der sker låsning.In this engagement between the ears 16 and the slider, its left end will be further pressed downwardly 20 to press against the strap. If desired, and to ensure said slider of said sliding member, the edges 35 of the gables 34 may be adjacent to the match portion 52, see FIG. 5, is arranged to partially engage the combat portion so that the slider is forcibly displaced to the left, as seen in the drawing when locking occurs.

Sammenfatningsvis vil glideorganet således ved låsningen påtrykkes kraftigt mod remmen, hvorhos påtryk-30 ningskraften ved glideorganets begge ender bliver temmelig ensformigt fordelt over glideorganet uden opståen af punktbelastninger, der kan skade remmen.In summary, the sliding member will thus be forcefully pressed against the belt during locking, whereby the compressive force at both ends of the sliding member is distributed fairly uniformly over the sliding member without the occurrence of point loads which may damage the belt.

For at forstærke friktionsvirkningen kan de med remmen indgribende flader af spændet forsynes med 148212 11 .In order to enhance the frictional effect, the surfaces engaging the belt with the belt can be provided with 148212 11.

1 en friktionsforøgende belægning eller behandles på en anden måde, fx ved opruning eller rifling.1 a friction-increasing coating or is treated in a different way, for example by rolling or rifling.

Ved låsningen glider som nævnt låsearmens 50 kamparti 5 mod indersiden af glideorganets bøjede tunge 36, og ved egnet valg af materiale tilstræbes mindst mulige friktion. Friktionen kan også formindskes ved at kampartiet eller excenterpartiet 52 omgives af en lejebøsning 53 af egnet materiale, der indsky-10 des mellem kampartiet og glideorganets tunge 36, som anskueliggjort i fig. 5a.As mentioned, in the locking, the fighting portion 5 of the locking arm 50 slides against the inside of the sliding tongue 36 of the slider, and in the appropriate choice of material, the least possible friction is sought. The friction can also be reduced by surrounding the combat portion or eccentric portion 52 by a bearing sleeve 53 of suitable material inserted between the combat portion and the tongue 36 of the slider as illustrated in FIG. 5a.

Den ovenfor beskrevne klemmevirkning som spændingen i remmen 75 udøver på glideorganets venstre ende 15 kan yderligere forstærkes hvis spændets hus modificeres som vist i fig. la. I dette tilfælde vil det sammensatte spændes venstre del få det udseende, som fig. 5b viser. Husets 10' venstre ende er således noget forlænget og dets bund optager her det yderli-20 gere spor 25, hvorved remmen 75 kan indtræde i spændet gennem dette spor, som vist i fig. 5b. Det anvendte glideorgan 30' har i dette tilfælde en tunge 41' der er meget kort eller er helt udeladt, eftersom faren for fejltrædning ved denne udførelsesform 25 for spændet er ubetydelig. I øvrigt passerer remmen glideorganet på samme måde som forud, og af fig.The clamping action described above which the tension in the belt 75 exerts on the left end 15 of the slider may be further enhanced if the housing of the tension is modified as shown in FIG. la. In this case, the left part of the composite clamp will have the appearance that FIG. 5b shows. The left end of the housing 10 'is thus somewhat extended and its bottom here occupies the additional groove 25, whereby the belt 75 can enter the clamp through this groove, as shown in FIG. 5b. In this case, the slider 30 'used has a tongue 41' which is very short or completely omitted, since the danger of misreading in this embodiment 25 for the buckle is negligible. Incidentally, the belt passes the slider in the same way as before, and from FIG.

5b fremgår det tydeligt, at remspændingen P får en på glideorganets 30' venstre ende virkende, nedad-rettet komposant P'', der er betydeligt forstærket 30 jævnført med komposanten P' ved udførelsen ifølge fig. 6. En yderligere forbedring af klemmévirkningen opnås, hvis der anvendes et hus 10'' udformet med en konveks bund 12'' j-følge fig. Ib.5b, it is clear that the belt tension P is provided with a downwardly directed component P 'acting on the left end of the slider 30', which is considerably amplified 30 as compared with the component P 'in the embodiment according to FIG. 6. A further improvement of the clamping effect is obtained if a housing 10 '' formed with a convex bottom 12 '' j following FIG. Ib.

148212 12 1 Efter låsningen, når således låsearmens gribeører eller håndtag 60 indtager en i fig. 6 og 7 vist nedsvinget stilling, befinder det ydre hus eller hylsterets 10 højre ører 18 sig ovenfor låsearmens 5 håndtag 60 på grund af de ovennævnte indskæringer 62 mellem håndtaget og broen 58 er således placeret, at de giver fri passage for ørerne 18 ved låsearmens nedsvingning. Den fra spændet udgående frie remdel 75 kan nu let krænge s ind mellem og under ørerne 10 18 til en stilling mellem disse og håndtaget 60, som vist i fig. 7. Herved hindres håndtaget effektivt mod utilsigtet at svinges mod åben stilling, på grund af at remmen selv danner en spærring mod denne bevægelse. Det skal dog påpeges, at spændingen P 15 i remmen, hvilken spænding via glideorganet 30 påvirker låsearmens kamparti eller excenterparti 52, ikke har nogen tilbøjelighed til at dreje låsearmen mod åben stilling, men det er naturligvis alligevel en stor fordel, at låsearmen på denne enkle måde 20 kan beskyttes mod ydre påvirkning, som kunne medføre, at armen utilsigtet blev svinget mod åben stilling.After locking, the gripping arms or handle 60 of the locking arm thus occupy one of FIG. 6 and 7, the outer ears 18 of the housing 10 or the housing 10 of the sheath 10 are located above the handle 60 of the locking arm 5 due to the above notches 62 between the handle and the bridge 58 so as to allow free passage of the ears 18 upon locking of the locking arm . The free belt portion 75 exiting the tension can now easily penetrate between and under the ears 10 18 to a position between them and the handle 60, as shown in FIG. 7. This effectively prevents the handle from inadvertently pivoting toward the open position, because the belt itself forms a lock against this movement. However, it should be noted that the tension P 15 in the belt, which tension via the slider 30 influences the locking arm or eccentric portion 52 of the locking arm, has no tendency to turn the locking arm towards the open position, but it is nevertheless a great advantage that the locking arm of this simple way 20 can be protected from external influences which could cause the arm to be inadvertently pivoted to open position.

Som forklaret ovenfor er det en stor fordel ved spændet ifølge opfindelsen, at det let kan læsnes 25 selv om det befinder sig under fuld belastning.As explained above, it is a great advantage of the clasp of the invention that it can be easily readable even under full load.

Når låsearmen 50 svinges op mod urvisernes bevægelsesretning, d.v.s. fra den i fig. 6 til den i fig.As the locking arm 50 is pivoted upwards in the clockwise direction of movement, i.e. from the one shown in FIG. 6 to that of FIG.

5 viste stilling, tvinger kampartiet 52 ved sin excentervirkning glideorganet 30 til at glide opad, 30 hvilket medfører at glideorganet letter fra remmen.5, the combat portion 52, by its eccentric action, forces the slider 30 to slide upwards, which causes the slider to release from the belt.

Bevægelsen sker altså tvangsmæssigt, og remmen eller båndet kan nu frit trækkes gennem spændet.The movement is thus forced, and the belt or belt can now be freely pulled through the strap.

Hvad angår materialet i spændet ifølge opfindelsen 148212 13 1 udføres dette ved større belastninger og grove remme hensigtsmæssigt af metal, fortrinsvis stål. Bånd og remme af de moderne plastmaterialer har en bemærkelsesværdig lastbæreevne, og som det fremgår af 5 ovenstående beskrivelse og tegninger kan spændet ifølge opfindelsen udføres særdeles kompakt og robust. Belastningen overføres gennem spændet praktisk taget direkte mellem de sammenkoblede remdele uden at fremkalde knækvirkning eller ekstreme momentbe-10 lastninger i spændets komponenter. Ved lettere remeller båndmateriale kan spændet ifølge opfindelsen meget vel udføres af egnede stærke plastmaterialer og derved danne et særdeles smidigt og lidet pladskrævende sammenkoblingselement for sådanne tyndere 15 bånd eller remme. Spændets konstruktion kan herved let tilpasses således, at dets komponenter egner sig for formsprøjtning eller formpresning i plastværktøj af enkel stempel-understempel-type. Således kan fx spændets hus 10 udformes således, at ørerne 20 16 og 18 ved spændets ender vil befinde sig vertikalt uden for hisets bund 12, som antydet ved stiplede linier i fig. 1, hvorhos spændets øvrige dele tilpasses derefter. Spændet kan også fremstilles ved præcisionsstøbning i letmetal.Concerning the material of the buckle according to the invention, this is carried out by larger loads and coarse belts, preferably of metal, preferably steel. The straps and straps of the modern plastic materials have a remarkable load carrying capacity, and as can be seen from the above description and drawings, the clamp according to the invention can be made extremely compact and robust. The load is transmitted through the clamp practically directly between the interconnected belt parts without causing cracking or extreme torque loads in the clamp components. In the case of lighter belt or belt material, the clasp of the invention may very well be made of suitable strong plastic materials, thereby forming a highly flexible and slightly space-consuming interconnecting element for such thinner belts or belts. The structure of the buckle can hereby be easily adapted so that its components are suitable for injection molding or injection molding in simple plunger-piston-type plastic tools. Thus, for example, the housing 10 of the strap may be designed such that the ears 20 and 18 at the ends of the strap will be vertically outside the bottom 12 of the elevator, as indicated by dashed lines in FIG. 1, wherein the other parts of the buckle are then adjusted. The buckle can also be manufactured by precision casting in light metal.
