DÆKSEL TIL EN SKAKTAFDÆKNING OG EN SKAKTAFDÆKNINGCOVER FOR A SHOCK COVER AND A SHOCK COVER

Frembringelsen angår et dæksel til en skaktafdækning og med mindst ét på dækslet anbragt låsemiddel, der har mindst én fjederarm med et indgrebsafsnit, der kan bringes i indgreb med en del afen ramme eller karm. Frembringelsen angår endvidere en skaktafdækning med et sådant dæksel og en ramme eller karm, der optager dette.The invention relates to a cover for a shaft cover and with at least one locking means disposed on the cover having at least one spring arm with an engaging section which can be engaged with part of a frame or frame. The production further relates to a shaft cover with such a cover and a frame or frame which accommodates this.

Skaktafdækninger med en sådan låsning, hvor indgrebet sædvanligvis finder sted som en slags arretering eller snaplåsning, er kendt og er i stort omfang i brug. Der henvises her eksempelvis til WO 86/04624, der beskriver et selvlåsende mandehulsdæksel, ved hvilket den fjedrende arm på dækslets underside er udformet på en afstivningsribbe og i det væsentlige strækker sig parallelt med en del af dækslets omkreds.Shaft covers with such locking, where the intervention usually takes place as a sort of arrest or snap lock, are known and are widely used. For example, reference is made to WO 86/04624 which describes a self-locking manhole cover in which the resilient arm on the underside of the cover is formed on a stiffening rib and extends substantially parallel to a portion of the circumference of the cover.

Ved den foreliggende frembringelse foreslås det at anbringe den fjedrende arm således, at dennes indgrebsafsnit i forhold til det tilgrænsende afsnit af dækslets omkreds er bevægelig under en vinkel, der er mindre end en ret vinkel.In the present invention, it is proposed to position the resilient arm such that its engagement portion relative to the adjacent portion of the circumference of the cover is movable at an angle less than a right angle.

Det har nemlig vist sig, at der ved konstruktionen ifølge frembringelsen kan opnås en låsning, der fungerer særligt effektivt, og som samtidigt er særlig simpel at betjene.It has been found that in the construction according to the invention a locking device which is particularly effective and which is at the same time particularly easy to operate can be obtained.

Specielt er fjederarmens indgrebsafsnit bevægeligt nogenlunde parallelt med det tilgrænsende afsnit af dækslets omkreds.In particular, the engagement portion of the spring arm is movable approximately parallel to the adjacent portion of the circumference of the cover.

Fjederarmens indgrebsafsnit strækker sig fortrinsvis under en vinkel i forhold til det tilgrænsende afsnit af dækslet.The engagement portion of the spring arm preferably extends at an angle with respect to the adjacent portion of the cover.

Ved en fælles videreudvikling af de ovenfor omtalte udførelsesformer strækker fjederarmens indgrebsafsnit sig nogenlunde under en ret vinkel med det tilgrænsende afsnit af dækslet. Ved et i det væsentlige cirkelformet dæksel kan fjederarmens indgrebsafsnit strække sig nogenlunde radialt, og især fjederarmen kan i det væsentlige være anbragt radialt.In a common further development of the above-mentioned embodiments, the engagement portion of the spring arm extends somewhat at a right angle with the adjacent portion of the cover. With a substantially circular cover, the engagement portion of the spring arm may extend somewhat radially, and in particular the spring arm may be substantially radially disposed.

For at forøge fjederegenskaberne kan fjederarmen fortrinsvis have et bueformet afsnit. Det bueformede afsnit kan så være anbragt mellem indgrebsafsnittet og et yderligere afsnit af fjederarmen, og de to afsnit kan nogenlunde flugte med hinanden.To increase the spring characteristics, the spring arm may preferably have an arcuate section. The arcuate section may then be disposed between the engagement section and a further section of the spring arm, and the two sections may be approximately aligned with one another.

En for øjeblikket særligt foretrukken udførelsesform udmærker sig ved, at låseorganet har to med indbyrdes afstand anbragte og fortrinsvis mindst afsnitsvis parallelt med hinanden forløbende fjederarme, hvorved låsemidlets låsevirkning kan forøges. I tilfælde af, at der anvendes et bueformet afsnit for begge fjederarme, skal disse hver især være krummet udefter, hvorved afstanden mellem de to fjederarme og dermed låsemidlets konstruktionsform ved denne udførelsesform kan gøres lille.A presently particularly preferred embodiment is characterized in that the locking means has two spaced apart and preferably at least partially parallel parallel spring arms, whereby the locking action of the locking means can be increased. In case an arcuate section is used for both spring arms, these must each be curved outwards, thereby reducing the distance between the two spring arms and thus the design of the locking means in this embodiment.

Indgrebsafsnittet har fortrinsvis et kileformet snaplåsafsnit, hvorved indgrebet finder sted som snaplåsning. Følgelig er snaplåsafsnittet forsynet med en i indgrebsretningen hældende flade. Desuden er det også muligt for at opnå en lettere udløsning ved snaplåsafsnittet at udforme en i modsat retning ligeledes hældende flade. Alternativt eller yderligere er det imidlertid også muligt 2 DK 2002 00198 U3 at udforme de tilsvarende indgrebsflader pi rammedelen kileformet eller hældende som skråflader.The engagement section preferably has a wedge-shaped snap-lock section, whereby the engagement takes place as a snap-lock. Accordingly, the snap-lock section is provided with a face inclined in the engagement direction. In addition, it is also possible to obtain a lighter release at the snap-lock section to form a surface inclined in the opposite direction. Alternatively or further, however, it is also possible to design the corresponding engagement surfaces of the frame part wedge-shaped or inclined as inclined surfaces.

Fjederarmen er fortrinsvis fastgjort til dækslet med en fra indgrebsafsnittet fjerntliggende ende. Sædvanligvis er låsemidlet anbragt på dækslets underside.The spring arm is preferably secured to the cover with a remote end from the engagement section. Usually, the locking means is located on the underside of the cover.

Såfremt dækslet er forsynet med afstivningsribber, skal låsemidlet være anbragt på dækslet i afstand fra afstivningsribberne, hvorved der opnås en særlig pladsbesparende anbringelse af låsemidlet.If the cover is provided with stiffening ribs, the locking means must be placed on the cover away from the stiffening ribs, thereby obtaining a special space-saving application of the locking means.

Ved en yderligere udførelsesform, ved hvilken dækslet har et indgrebsmiddel for et værktøj, er dette indgrebsmiddel anbragt i afstand fra låsemidlet og således udformet, at værktøjet ved indgreb med dette indgrebsmiddel samtidigt kan bringes i indgreb med en del af rammen for derved at påvirke dækslet med et vægtstangsmoment og således at løsne dækslet fra rammen mod indvirkningen af fjederarmens fjederkraft. Denne udførelsesform tillader således, at dækslet løftes ud af rammen ved hjælp af værktøjet, uden at der med dette værktøj indvirkes på låsemidlet. Indgrebsmidlet har fortrinsvis en udsparing, gennem hvilken værktøjet kan indføres.In a further embodiment, in which the cover has an engagement means for a tool, this engagement means is spaced apart from the locking means and is designed so that the tool, when engaged with this engagement means, can be simultaneously engaged with a part of the frame, thereby affecting the cover with a lever torque and thus loosening the cover from the frame against the action of the spring force of the spring arm. This embodiment thus permits the cover to be lifted out of the frame by the tool without having any effect on the locking means with this tool. The engagement means preferably has a recess through which the tool can be inserted.

Endelig skal det på dette sted yderligere omtales, at der på dækslet sædvanligvis findes to låsemidler, der ligger over for hinanden, og som ved et cirkelformet dæksel ligger radialt over for hinanden.Finally, it should be further mentioned at this point that there are usually two locking means which are opposite each other on the cover and which are radially opposite to one another with a circular cover.

I det følgende vil to foretrukne udførelsesformer for frembringelsen blive nærmere beskrevet under henvisning til de medfølgende figurer. Pa disse viser: fig. 1 en fragmenteret ramme for en skaktafdækning set fra oven, fig. 2 et tværsnit i den i fig. 1 viste ramme efter den i fig. 1 viste stiplede linje II-II, fig. 3 en forstørret detalje af et afsnit af den i fig. 1 viste ramme med en snaplåsudsparing og set i den retning, der i fig. 1 er vist med en pil III, fig. 4 en afbildning af undersiden af et dæksel for skaktafdækningen med en låseindretning ifølge en første udførelsesform, fig. 5 et tværsnit i det i fig. 4 viste dæksel langs den i fig. 4 viste stiplede linje V-V, fig. 6 et delsnit i en detalje i dækket ifølge fig. 4 langs den i fig. 4 viste stiplede linje VI-VI, fig. 7 en afbildning af undersiden af et dæksel for skaktafdækningen med en låseindretning ifølge en anden udførelsesform, fig. 8 et snit i en detalje af dækslet ifølge fig. 7 langs den i fig. 7 viste stiplede linje VIII-VIII, og 3 DK 2002 00198 U3 fig. 9 et tværsnit i omkredsafsnittet for anordningen af dæksel og ramme med et værktøj til at løfte dæksiet ud af rammen.In the following, two preferred embodiments of the invention will be described in more detail with reference to the accompanying figures. In the following: FIG. 1 is a fragmentary top view of a shaft cover; FIG. 2 is a cross-sectional view in the embodiment of FIG. 1 according to the frame shown in FIG. 1 is a dotted line II-II; FIG. 3 is an enlarged detail of a section of the embodiment of FIG. 1 with a snap lock recess and seen in the direction shown in FIG. 1 is indicated by an arrow III; FIG. 4 is a view of the underside of a cover of the shaft cover with a locking device according to a first embodiment; FIG. 5 is a cross-sectional view in the embodiment of FIG. 4, along the cover shown in FIG. 4 is a dotted line V-V, fig. 6 is a fragmentary sectional view of a tire of FIG. 4 along the line shown in FIG. 4 is a dotted line VI-VI; FIG. 7 is a view of the underside of a cover for the shaft cover with a locking device according to another embodiment; FIG. 8 is a sectional view of a detail of the cover of FIG. 7 along the line shown in FIG. 7 shows dotted line VIII-VIII, and 3 FIG. 9 is a cross-section in the circumferential section of the cover and frame assembly with a tool for lifting the cover out of the frame.

Den i det følgende beskrevne skaktafdækning har en ringformet ramme 1 og et dertil passende skiveformet dæksel 10. Rammen 1 er vist i fig. 1 til 3, og dækslet 10 med en låseindretning i en første udførelsesform er vist i fig. 4 til 6 og i en anden udførelsesform i fig. 7 og 8.The shaft cover described below has an annular frame 1 and a suitable disc-shaped cover 10. The frame 1 is shown in FIG. 1 to 3, and the cover 10 with a locking device in a first embodiment is shown in FIG. 4 to 6 and in another embodiment of FIG. 7 and 8.

Den i fig. 1 og 2 viste ramme 1 har pi sin inderside en indefter ragende, omløbende ribbe eller flange 2, hvis overside 2a danner en understøtningsflade for dækslet 10, og som ligger i et plan, der i rammen l's indbyggede tilstand strækker sig i det væsentlige vandret. På flangen 2 er der anbragt et indad ragende, omløbende flangeagtigt fremspring 4, der ved den viste udførelsesform på to over for hinanden liggende steder er afbrudt af en udsparing 6. Som det fremgår af fig. 3 begrænses hver af disse udsparinger 6 ved begge ender af det flangeagtige fremspring 4 af udefter spidst mod hinanden forløbende øverste og nederste skråflader 6a og 6b.The FIG. The frame 1 shown in Figures 1 and 2 has on its inside an inwardly projecting, circumferential rib or flange 2, the upper surface of which 2a forms a support surface for the cover 10, and which lies in a plane extending substantially in the horizontal state of the frame 1. On the flange 2 is arranged an inwardly extending, circumferential flange-like projection 4, which in the illustrated embodiment is interrupted at two opposite locations by a recess 6. As can be seen in FIG. 3, each of these recesses 6 is restricted at both ends of the flange-like projection 4 by outwardly extending upper and lower inclined surfaces 6a and 6b.

Dækslet 10 har på sin underside en langs omkredsen forløbende ribbe eller flange 12 (se især fig. 4, 5 og 7), med hvilken dækslet 10, når det indsættes i rammen 1, ligger an mod den som understøtningsflade tjenende overside 2a af den omløbende flange 2 på rammen 1. Endvidere er dækslet 10 på sin underside forsynet med radialt forløbende afstivningsribber 14.The cover 10 has on its underside a circumferentially extending rib or flange 12 (see in particular Figs. 4, 5 and 7), with the cover 10, when inserted into the frame 1, abuts the upper surface 2a of the circumferential surface serving as a support surface. flange 2 on the frame 1. Furthermore, the cover 10 on its underside is provided with radially extending stiffening ribs 14.

På to radialt over for hinanden beliggende steder er der i afstand fra ribberne 14 på undersiden af dækslet 10 anbragt to klodser eller knaster 16, på hver af hvilke der er udformet to fjederarme 18. Fjederarmene 18 er anbragt frit svævende på den pågældende klods 16 og er rettet radialt udefter i retning af dækslet 10's omkreds 10a. Fjederarmene 18 i hvert par af fjederarme 18 strækker sig således parallelt med hinanden og med dækslet 10 samt i en afstand fra dettes underside. Således ligger fjederarmene 18 i skaktafdækningens samlede tilstand med dækslet 10 indsat i rammen 1 nogenlunde i et vandret plan, der forløber parallelt med og i afstand fra det af dækslet 10 bestemte plan.At two radially opposite locations, two blocks or knobs 16 are spaced apart from the ribs 14 on the underside of the cover 10, on each of which are formed two spring arms 18. The spring arms 18 are freely suspended on the respective block 16 and is directed radially outwards in the direction of the circumference 10a of the cover 10. The spring arms 18 in each pair of spring arms 18 thus extend parallel to each other and to the cover 10 and at a distance from the underside thereof. Thus, the spring arms 18 lie in the overall state of the shaft cover with the cover 10 inserted in the frame 1 roughly in a horizontal plane extending parallel to and spaced from the plane determined by the cover 10.

Hver anordning af klodsen 16 og det derpå anbragte par af fjederarme 18 danner et låsemiddel til at fastlåse dækslet 10 til rammen 1. Med dette formål er fjederarmene 18 mod virkningen af en iboende tilbageførende fjederkraft med deres frie ender 18a bevægelige mod hinanden og således i retning af dækslet 10's omkreds 10a og tjener som snaplåselementer til snaplåsning i rammen l's udsparing 6.Each arrangement of the bracket 16 and the pair of spring arms 18 provided therewith provide a locking means for locking the cover 10 to the frame 1. For this purpose, the spring arms 18 are movable towards each other against the action of an inherently retractable spring force and thus in a direction. of the circumference 10a of the cover 10 and serves as snap-locking elements for snap-locking in the recess 6 of the frame 1.

Ved den i fig. 4 og 6 viste udførelsesform er fjederarmene 18 udformet retlinjet og forsynet med en kileformet yderside, der dannes afen hældende øverste skråflade 18b og en hældende nederste skråflade 18c, idet de to hældende skråflader 18b og 18c forløber spidst udefter mod hinanden, som det fremgår af fig. 6.In the embodiment shown in FIG. 4 and 6, the spring arms 18 are formed rectilinear and provided with a wedge-shaped outer surface formed by the sloping upper sloping surface 18b and a sloping lower sloping surface 18c, the two sloping sloping surfaces 18b and 18c extending pointedly towards one another, as can be seen in FIG. . 6th

Dækslet 10 anbringes således på rammen 1, at de frie ender 18a af fjederarmene 18 ligger ud for udsparingerne 6. Således kommer de frie ender 18a af fjederarmene 18 først med deres nederste skråflader 18c til at ligge an mod de øverste skråflader 6a på rammen l's udsparing 6. Ved fortsat bevægelse af dækslet 10 mod rammen 1 bevirker de øverste skråflader 6a i udsparingen 6, at fjederarmene 18 ved deres frie ender 18a trykkes sammen, indtil de passerer det af de to skråflader 6a, 6b dannede indsnævrede sted i udsparingen 6. Følgelig er lysningsbredden for det af skråfladerne 6a, 6b dannede indsnævrede sted af udsparingen 6 en 4 DK 2002 00198 U3 lille smule større end summen af bredden af fjederarmene 18's frie ender 18a regnet i retning af dækslet 10's omkreds 10a. Indtil det indsnævrede sted i udsparingen 6 passeres, bliver fjederarmene 18 altså sammentrykket mod virkningen af den iboende tilbageførende fjederkraft. Efter at det indsnævrede sted i udsparingen 6 er passeret, bevirker den i fjederarmene 18 iboende fjederkraft ved fortsat bevægelse af dækslet 10 mod rammen 1 en tilbageføring af fjederarmene til den i figurerne 4 og 6 viste position, hvorved de frie ender 18a af fjederarmene 18 nu med deres øverste skråflader 18b kommer til at ligge an mod udsparingen 6's skråflader 6b og på denne måde griber ind bag de afsnit af rammen l's flangeagtige fremspring 4, der begrænser udsparingen 6.The cover 10 is positioned on the frame 1 so that the free ends 18a of the spring arms 18 lie against the recesses 6. Thus, the free ends 18a of the spring arms 18 first come into contact with the lower sloping surfaces 18c of the upper sloping surfaces 6a on the recess of the frame 1 6. By continuing to move the cover 10 toward the frame 1, the upper sloping surfaces 6a of the recess 6 cause the spring arms 18 at their free ends 18a to be compressed until they pass the narrowed place formed by the two sloping surfaces 6a, 6b in the recess 6. Accordingly For example, the luminous width of the narrowed location of the recess 6 formed by the sloping surfaces 6a, 6b is a little greater than the sum of the width of the free ends 18a of the spring arms 18 in the direction of the circumference 10a of the cover 10. Thus, until the narrowed location in the recess 6 is passed, the spring arms 18 are compressed against the action of the inherent return spring force. After the constricted location in the recess 6 is passed, the spring force inherent in the spring arms 18, upon continued movement of the cover 10 against the frame 1, returns the spring arms to the position shown in figures 4 and 6, whereby the free ends 18a of the spring arms 18 now with their upper sloping surfaces 18b, abut the sloping surfaces 6b of the recess 6 and in this way intervene behind the portions of the flange-like projections 4 of the frame 1 which restrict the recess 6.

Således danner fjederarmene 18 med deres frie ender 18a på dækslet 10 og udsparingerne 6 i rammen 1 en arreterende låsning eller en snaplåsning.Thus, the spring arms 18 with their free ends 18a on the cover 10 and the recesses 6 in the frame 1 form an arresting lock or snap lock.

I fig. 7 og 8 er der vist en anden udførelsesform for den på dækslet 10's underside udformede låsning. Fjederarmene 18' ved denne anden udførelsesform er ganske vist ligesom ved den i fig.In FIG. 7 and 8, another embodiment of the locking formed on the underside of the cover 10 is shown. The spring arms 18 'in this second embodiment are admittedly like the one shown in FIG.

4 og 6 viste første udførelsesform via en klods eller en knast 16' udformet på dækslet 10's underside og på samme måde på deres yderside forsynet med øverste og nederste skråflader 18b1 og 18c'. Imidlertid adskiller den anden udførelsesform sig fra den første udførelsesform derved, at fjederarmene 18' mellem de frie ender 18a' og en til klodsen 16' grænsende afsnit 18e' har et udefter bøjet afsnit 18d', idet de bøjede afsnit 18d' af de to fjederarme 18' i hvert par fjederarme 18' ved den viste anden udførelsesform er udformet symmetrisk i forhold til hinanden og således, at de to afsnit 18a' og 18e' flugter med hinanden. De bøjede afsnit 18d' af fjederarmene 18' tjener til at forøge den tilbageførende fjederkraft. Hvad angår de øvrige træk og især den arreterende eller snaplåsende låsevirkning henvises der til den ovenfor i forbindelse med fig. 4 og 6 givende beskrivelse af den første udførelsesform.4 and 6 are shown by means of a block or cam 16 'formed on the underside of the cover 10 and similarly on their outer surface provided with upper and lower sloping surfaces 18b1 and 18c'. However, the second embodiment differs from the first embodiment in that the spring arms 18 'between the free ends 18a' and a section 18e 'adjacent to the block 16' have an outwardly bent section 18d ', the bent sections 18d' of the two spring arms 18 'in each pair of spring arms 18' in the second embodiment shown is symmetrical with respect to each other and so that the two sections 18a 'and 18e' align with each other. The bent sections 18d 'of the spring arms 18' serve to increase the return spring force. With regard to the other features and especially the arresting or snap-locking action, reference is made to the above in connection with FIG. 4 and 6 give descriptive description of the first embodiment.

For at frigøre det på rammen 1 anbragte og fastlåste dæksel 10 indføres et stangformet værktøj 32 gennem en ved dækslet 10's omkreds 10a udformede udsparing 30 og bringes således i indgreb med et derunder liggende afsnit af rammen 1, at værktøjet frembringer en vægtstangsvirkning, der gør det muligt at løfte dækslet 10 op fra rammen 1, som det er vist i fig. 9. Denne vægtstangsvirkning skal da være således afpasset, at fjederarmene 18's tilbageførende fjederkraft overvindes, og at de frie ender 18a af fjederarmene 18 derfor ved afløftning af dækslet 10 fra rammen 1 kan bevæges langs de nederste skråflader 6b af udsparingen 6 i retning af dennes indsnævrede sted. Derved bliver fjederarmene 18 igen trykket sammen, indtil de ved fortsat bevægelse af dækslet passerer det indsnævrede sted af udsparingen 6 bort fra rammen 1.To release the cover 10 secured to the frame 1, a rod-shaped tool 32 is inserted through a recess 30 formed at the circumference 10a of the cover 10, and is brought into engagement with an underlying portion of the frame 1 to produce a lever action which makes it it is possible to lift the cover 10 from the frame 1, as shown in FIG. 9. This lever action must then be adapted so that the return spring force of the spring arms 18 is overcome and that the free ends 18a of the spring arms 18 can therefore be moved by lifting the cover 10 from the frame 1 along the lower inclined surfaces 6b of the recess 6 in the direction of its narrowing place. Thereby, the spring arms 18 are compressed again until, by continued movement of the cover, the narrowed place of the recess 6 passes away from the frame 1.
