Description

DK 163593 BDK 163593 B

Opfindelsen angår et lukkeorgan til låger, døre, fløje, skuffer og lignende og af den i krav l's indledning angivne 5 art.The invention relates to a closing means for doors, doors, wings, drawers and the like and of the kind specified in the preamble of claim 1.

Ved pladekapslede elektriske anlæg til stærkstrøm stilles der ved visse anvendelser krav om, at døre og låger ikke må kunne springe op, selvom der opstår en lysbue, f.eks. fra 10 en kortslutning bag døren eller lågen, og der herved momentant opstår et stort gas- eller lufttryk fra lysbuen, også selvom der findes midler til bortledning af gas- eller lufttrykket. Hermed stilles der meget store krav til lukketøjet, dels til dets styrke og dels til dets konstruktion, 15 så det sikres, at lågen ikke kan lukkes, uden at lukkeorganet er i sikkert indgreb med det tilhørende holdeorgan eller lignende midler i karm eller stolpe.In case of plate-enclosed electrical systems for high current, certain applications require that doors and doors must not be able to open even if an arc arises, e.g. from 10 a short circuit behind the door or door, and thus instantaneous large gas or air pressure arises from the arc, even if there are means for dissipating the gas or air pressure. This places very high demands on the closure, partly for its strength and partly for its construction, so as to ensure that the door cannot be closed without the closure member being securely engaged with the corresponding holding means or similar means in the frame or post.

Også til andre anvendelser, f.eks. ovndøre, døre til frost-20 rum eller kemikalieskabe og lignende, har det stor betydning, at en ilukning af en låge eller dør betyder, at dens lukketøj er i sikkert og solidt indgreb med karm eller stolpe, så døren ikke kan springe op ved påvirkninger indefra, men kun kan åbnes med håndgrebet.Also for other applications, e.g. oven doors, doors to frost-20 compartments or chemical cabinets and the like, it is of great importance that the closing of a door or door means that its closure is securely and firmly engaged with a frame or post, so that the door cannot open when exposed from the inside, but can only be opened with the handle.

Kendte lukkeorganer til sådanne anvendelser kan være udformet således, at man enten skal anvende værktøj eller nøgle for at lukke en fløj, eller man skal manuelt bruge fingerskruer eller lignende, inden fløjen kan lukkes.Known closure means for such applications may be designed such that either tool or key must be used to close a wing, or manually using finger screws or the like before the wing can be closed.

Fra USA patent nr, 4.489.966 kendes et lukkeorgan af den i krav 1's indledning angivne art, men som omfatter en meget kompliceret mekanisme med mange samvirkende enkeltdele, der skal fungere i forbindelse med åbning og lukning af en fløj 35 eller låge til et pladekapslet elektrisk anlæg. Denne konstruktion har desuden den ulempe, at den fylder meget, ogU.S. Patent No. 4,489,966 discloses a closure means of the kind set forth in the preamble of claim 1, but which comprises a very complicated mechanism with many interacting single parts to operate in opening and closing a wing 35 or cover of a plate encased electrical system. In addition, this construction has the disadvantage of being very filling, and

DK 163593 BDK 163593 B

2 at den kræver flere forskellige fjederelementer og mange bevægelige dele, hvilket øger mulighederne for fejl i forbindelse med samling af delene og i øvrigt øger mulighederne for fejlfunktionering. Denne konstruktion har desuden 5 ikke nogen sikker mekanisme, der sikrer, at den fjedermeka nisme, der skal manøvrere lukkeorganet, altid bliver spændt, når fløjen åbnes.2 that it requires several different spring elements and many moving parts, which increases the possibility of errors in connection with the parts and in addition increases the possibilities of malfunctioning. In addition, this construction does not have a secure mechanism which ensures that the spring mechanism to actuate the closing means is always tightened when the wing is opened.

Formålet med opfindelsen er at angive et lukkeorgan af den 10 art, der er indrettet således, at når fløjen eller skuffen lukkes i, sker der en automatisk lukning og tilspænding i sidste fase af lukningen, men hvor dette opnås med en mekanisk meget enkel og dermed meget driftsikker funktion, og som yderligere er indrettet således, at det ikke er muligt 15 at åbne fløjen eller skuffen, uden at fjederen bliver spændt igen.The object of the invention is to provide a closure member of the kind arranged so that when the wing or drawer is closed, an automatic closure and tightening takes place in the last phase of the closure, but where this is achieved with a mechanical very simple and thus very reliable operation and further arranged such that it is not possible to open the wing or drawer without the spring being retightened.

Dette opnås ved at udforme lukkeorganet ifølge opfindelsen som angivet i krav l's kendetegnende del. Når en fløj eller 20 en skuffe med et lukkeorgan ifølge opfindelsen lukkes, d.v.s. føres mod karm eller stolpe med holdeorgan ifølge opfindelsen, udløses den oplagrede energi i det mekaniske energilager, og rigelen går i fast og solidt indgreb med sporene i holdeorganet, og kan kun føres ud af indgreb her-25 med ved drejning af håndtaget, men f.eks. ikke ved en kraftig trykpåvirkning, f.eks. fra en eksplosion eller lysbue i det af fløjen afspærrede område. Energilageret, der sædvanligvis vil være en stålfjeder, vil automatisk blive spændt, når fløjen eller skuffen åbnes på korrekt måde ved hjælp af 30 håndtaget.This is achieved by designing the closure means according to the invention as set forth in the characterizing part of claim 1. When a wing or drawer with a closure member according to the invention is closed, i.e. directed against the frame or post with holding means according to the invention, the stored energy is released into the mechanical energy storage and the bolt engages firmly and firmly with the grooves in the holding means, and can only be released from engagement with this by turning the handle, but .g. not by excessive pressure, e.g. from an explosion or arc in the wing blocked area. The energy storage, which will usually be a steel spring, will automatically be tightened when the wing or drawer is opened properly using the handle.

Lukkeorganets eneste bevægelige del er en aksel, der drejes om sin længdeakse, således at de dele, der er solidt fastgjort til akslen, følger med. Dette giver en robust og so-35 lid konstruktion, der altid fungerer præcist.The only movable member of the closure member is a shaft rotated about its longitudinal axis so that the parts firmly attached to the shaft follow. This provides a robust and so-35 lid construction that always works precisely.

Lukkeorganet bliver meget driftsikkert og kan, fordi det kun består af få enkeltdele, fremstilles med særdeles rimelige omkostninger.The closure means becomes very reliable and, because it consists of only a few parts, can be manufactured at very reasonable costs.

5 Ved at udforme lukkeorganet ifølge opfindelsen som angivet i krav 2' s kendetegnende del vil udløserorganet være upåvirket når fløjen er korrekt lukket, hvilket medfører øget levetid for lukkeorganet.By designing the closure means according to the invention as set forth in the characterizing part of claim 2, the release means will be unaffected when the wing is properly closed, resulting in increased life of the closure member.

10 Ved at udforme lukkeorganet ifølge opfindelsen som angivet i krav 3's eller 4's kendetegnende dele fås på enkel og driftsikker måde delene koblet fast sammen.By forming the closure means according to the invention as defined in the characterizing parts of claim 3 or 4, the parts are connected in a simple and reliable manner.

Udløserorganet i lukkeorganet kan være udformet som angivet 15 i krav 5's kendetegnende del, der anviser en mulig udførelsesform for opfindelsen, idet udløserorganet hermed får en yderligere funktion, nemlig sikring af, at man ved åbning af fløjen ved hjælp af det udvendige håndtag på skabet, ikke kan undgå at få spændt fjederen tilstrækkeligt, idet 20 fløjen først kan åbnes, når fjederen er spændt og udløseren er fastholdt i indgreb med kanten af åbningen i låsehuset.The release member of the closure member may be configured as defined in the characterizing portion of claim 5, which indicates a possible embodiment of the invention, thereby releasing the additional means, namely ensuring that when opening the wing by means of the outer handle of the cabinet, The spring cannot be opened until the spring is tensioned and the trigger is engaged in engagement with the edge of the opening in the lock housing.

Ved denne udformning får udløserorganet en begrænset bevægelsesmulighed og kan ikke ødelægges, selv ved voldsom åbning eller lukning af fløjen.In this embodiment, the trigger means has a limited range of motion and cannot be destroyed, even by violent opening or closing of the wing.

2525

Lukkeorganet ifølge opfindelsen er fortrinsvis udformet som angivet i krav 6's kendetegnende del, idet man hermed får mulighed for at samle og sammenholde delene på en enkel og praktisk måde og får en stærk konstruktion, der kan gå i 30 meget solidt indgreb med holdeorganet.The closure means according to the invention is preferably designed as defined in the characterizing part of claim 6, thereby giving the possibility to assemble and compare the parts in a simple and practical manner and to obtain a strong construction which can engage very firmly with the holding means.

Selvom lukkeorganet ifølge opfindelsen kan anvendes mange forskellige steder, er det især udviklet til anvendelse i forbindelse med fløje, såsom låger, døre, lemme, skuffer 35 m.v. i pladekapslede elektriske stærkstrømsanlæg, som angivet i krav 7. Herved får man sikkerhed for, at lukningen afAlthough the closure means of the invention can be used in many different places, it is especially designed for use in connection with wings such as doors, doors, hinges, drawers 35 and so on. in plate-enclosed electric high-power systems, as specified in claim 7. This ensures that the closure of

7 til at være i indgreb med udløserfjederen 11. Holdeorganet omfatter desuden en U-formet fjeder 11 af plademateriale, f.eks. rustfrit stål. Udløserfjederen 11 fastholdes til stolpen 2 sammen med låseorganet 7, således at en fri ende 5 rager fremad. Den frie ende er udformet og bukket således, at der fremkommer to dele 25 og 26, se fig. 2 og 5, der udgør en fremadvendende kroglignende del og et vinkelbukket område 24, der støtter den kroglignende del, så den ikke kan bevæges sideværts eller fremad på grund af fingeren 9 10 på holdeorganet 7. Den kroglignende del 25, 26 kan dog bevæges ind mod stolpen 2 mod udløserf jederen 11's fjederkraft.7 to engage the release spring 11. The holding means further comprises a U-shaped spring 11 of sheet material, e.g. stainless steel. The release spring 11 is secured to the post 2 together with the locking member 7 so that a free end 5 protrudes forward. The free end is formed and bent so that two parts 25 and 26 appear, see FIG. 2 and 5 constituting a forward-facing hook-like portion and an angled region 24 supporting the hook-like portion so that it cannot be moved laterally or forwardly by the finger 9 10 of the holding member 7. However, the hook-like portion 25, 26 may be moved in toward the post 2 against the spring force of the spring 11.

På fig. 5 ses udløserfjederen 11's funktion fra siden under 15 henholdsvis lukning (fig. 5A) og åbning (fig. 5B) af en fløj med et lukkeorgan ifølge opfindelsen. På fig. 6 ses udløserf jederens 11 samvirken med udløseren 13 set i retningen mod holdeorganet gennem huset, jfr. pilen mærket fig. 6 i fig. 4, idet fig. 6A viser delenes position i luk-20 keøjeblikket, umiddelbart før den forsatte kant 14 går fri af åbningen 12, hvilket svarer til fig. 5A. I fig. 6C ses situationen et øjeblik senere, nemlig når riglen er gået i indgreb med holdeorganet, og det ses, at udløserfjederen rager frit ind gennem åbningen 12, fordi den udragende, 25 forsatte del jo følger med akselens drejning. På fig. 6B ses delene under åbning af fløjen svarende til fig. 5B, og hvor udløserfjederen 11’s kroglignende del 26 er "bag" udløserskiven 13 og trækker den mod åbningen 12.In FIG. 5, the function of the release spring 11 is seen from the side during closing 15 (Fig. 5A) and opening (Fig. 5B), respectively, of a wing with a closure member according to the invention. In FIG. 6, the interaction of the trigger 11 with the trigger 13 is seen in the direction towards the holding means through the housing, cf. the arrow labeled fig. 6 in FIG. 4, FIG. 6A shows the position of the parts at the closing moment, immediately before the offset edge 14 clears from the opening 12, which corresponds to FIG. 5A. In FIG. 6C, the situation is seen a moment later, namely when the bolt engages with the holding means, and it is seen that the release spring projects freely through the opening 12, because the protruding 25 part follows the rotation of the shaft. In FIG. 6B, the parts are seen during opening of the wing similar to FIG. 5B, and wherein the hook-like portion 26 of the spring 11 is "behind" the release disc 13 and pulls it toward the opening 12.

30 Lukkeorganet ifølge opfindelsen virker som følger. Når fløjen 1 er lukket mod stolpen 2 vil rigelen 4’s ruller 20 være i fast indgreb med sporene 8 i holdeorganet 7. Fløjen åbnes i det viste eksempel ved at dreje håndtaget 3 i retningen mod uret. Samtidig hermed drejes akslen 5, 5' og 35 fjederen 15 spændes og fordi fjederen 15 trykker skiverne 16 og 13 mod husdelens 6' indvendige side, og udløserfjede- 8The closure according to the invention works as follows. When the wing 1 is closed against the post 2, the rollers 20 of the latch 4 will be firmly engaged with the grooves 8 in the holding member 7. The wing is opened in the example shown by turning the handle 3 in the counterclockwise direction. At the same time, shaft 5, 5 'and 35 spring 15 is tightened and because spring 15 presses washers 16 and 13 towards the inside of housing 6' and release spring 8

ren 11 (se fig. 5B og 6B) trykker udløserskivens 13 udragende, forsatte del mod åbningen 12, vil udløserskivens 13 låsekant 14 smutte ud i hullet 12 og når håndtaget 3 slippes, vil kanten 14 med sikkerhed hvile mod hullets 12 5 rand (se fig. 3) og fjederen vil forblive spændt. Dette sker samtidig med, at rigelen går fri af holdeorganet, så man ikke kan åbne fløjen, uden at spænde fjederen.Clean 11 (see Figs. 5B and 6B) presses the protruding, biased portion of the release disc 13 toward the opening 12, the locking edge 14 of the release disc 13 will protrude into the hole 12, and when the handle 3 is released, the edge 14 will rest safely against the rim of the hole 12 (see FIG. Fig. 3) and the spring will remain tense. This is done at the same time as the bolt is released from the holding means so that the wing cannot be opened without tightening the spring.

Når fløjen 1 lukkes, vil udløserfjederen 11*s kroglignende 10 del 26trykke udløserskiven 13 så meget ind i huset, at kanten 14 går fri af åbningen 12 og fjederkraften i fjederen 15 vil sikre, at rigelen går i fast og sikkert indgreb med sporene 8, og at rigelen forbliver i indgreb hermed. Fløjen 1 kan altså ikke lukkes, uden at lukkeorganet sikrer en so-15 lid fastholdelse af fløjen mod stolpen 2. Fjederen 11 er ligesom fjederen 15 en solid fjeder, f.eks. af rustfrit stål, der kan tåle store mekaniske påvirkninger uden at ødelægges.When the wing 1 is closed, the hook-like 10 portion of the release spring 11 * will push the release disc 13 so much into the housing that the edge 14 is released from the opening 12 and the spring force of the spring 15 will ensure that the bolt engages the grooves 8 securely and securely. and that the bolt remains engaged. Thus, the wing 1 cannot be closed without the closure member securing a sole member of the wing against the post 2. The spring 11, like the spring 15, is a solid spring, e.g. made of stainless steel that can withstand large mechanical stresses without being destroyed.
