Description

Oppfinnelsen vedrører hurtiglåsing. The invention relates to quick locking.

Mere spesielt er den foreliggende oppfinnelse beregnet på å tilveiebringe en god og produksjonsvennlig låsemetode for ben, som benyttes for å oppnå en ergonomisk riktig arbeidsstilling ved arbeide med f.eks. tangentbord, enklere tegnebord, gjennom-lysningsskap, etc. Oppfinnelsen kan også benyttes for andre formål, hvis man ønsker en låseanordning som kan fremstilles sikkert og enkelt. More particularly, the present invention is intended to provide a good and production-friendly locking method for legs, which is used to achieve an ergonomically correct working position when working with e.g. keyboard, simpler drawing table, see-through cabinet, etc. The invention can also be used for other purposes, if you want a locking device that can be manufactured safely and easily.

Det som først og fremst er kjennetegnende for en anordningWhat is primarily characteristic of a device

ved hurtiglåsing ifølge den foreliggende oppfinnelse fremgår av patentkravene. in the case of quick locking according to the present invention appears from the patent claims.

Oppfinnelsen skal i det følgende forklares nærmere ved hjelp av et utførelseseksempel for en anordning for hurtiglåsing ifølge oppfinnelsen, som er fremstilt på tegningen, som viser: fig. 1 en første detalj, som er låst med hurtiglås i en inn- felt dreiestilling i forhold til en annen konstruksjonsdetalj , In the following, the invention will be explained in more detail with the help of an embodiment of a device for quick locking according to the invention, which is shown in the drawing, which shows: fig. 1 a first detail, which is locked with a quick lock in an in- field pivot position in relation to another structural detail,

fig. 2 den første konstruksjonsdetalj i en dreiestilling uten fig. 2 the first structural detail in a pivoting position without

hurtiglåsingseffekt,quick lock effect,

fig. 3 den første konstruksjonsdetalj låst med hurtiglås ifig. 3 the first construction detail locked with quick lock i

en utfelt dreiestilling i forhold til den andre detalj, an unfolded pivot position in relation to the other detail,

samt .as well as .

fig. 4 i større målestokk en noe annerledes utførelse av den første konstruksjonsdetalj og en del av den andre konstruksjonsdetalj . fig. 4 on a larger scale, a somewhat different embodiment of the first construction detail and part of the second construction detail.

Den første konstruksjonsdetalj 1, som er illustrert i de ved-lagte tegninger, består av en, alternativt to deler. Den ene ende 2 av konstruksjonsdetaljen eller -delen 1 kjennetegnes ved å være i det vesentlige sirkelformet og utført av et fjæ-rende, holdbart materiale, som f.eks. glassfiberforsterket termoplast. Den andre ende 3 av konstruksjonsdelen er kjenne- tegnet ved å være utført av et friksjonsmateriale, som f.eks. "dexmopane" som enten limes eller skrus fast i konstruksjonsdelen. Alternativt anbringes friksjonsmaterialet■ved dobbelt-støping. The first construction detail 1, which is illustrated in the attached drawings, consists of one, alternatively two parts. One end 2 of the construction detail or part 1 is characterized by being essentially circular and made of a resilient, durable material, such as e.g. fiberglass reinforced thermoplastic. The other end 3 of the structural part is characterized by being made of a friction material, such as e.g. "dexmopane" which is either glued or screwed into the construction part. Alternatively, the friction material■is placed by double casting.

Den første konstruksjonsdel kjennetegnes videre ved at en ytre halvsirkelformet ring 4 er utformet i delens ene ende 2. Denne ring har i omkretsen minst to - adskilte - nedsenkninger 5 The first structural part is further characterized by the fact that an outer semicircular ring 4 is formed at one end 2 of the part. This ring has at least two - separated - immersions 5 in its circumference

og 6, som på sin side har motsvarighet i nedsenkinger 7 og 8 i den indre sirkelformede periferiflate 9. Konstruksjonsdelen forløper rundt det markerte sentrum 10 for hullet. Når en ytre tapp 11, som utgjør en integrert del av den andre konstruksjonsdetalj 12, trykker mot den beskrevne ring, trykkes denne inn mot den nedre periferiflate, slik at en "fast" stilling oppstår, når tappen har passert frem til en av de nedsenkede stillinger ifølge fig. 1 henholdsvis fig. 3. For at den første detalj skal kunne vris videre i forhold til den andre detalj 12 kreves til å begynne med et betydelig større dreiemoment. and 6, which in turn have a counterpart in recesses 7 and 8 in the inner circular peripheral surface 9. The construction part extends around the marked center 10 for the hole. When an outer pin 11, which forms an integral part of the second structural detail 12, presses against the described ring, this is pressed against the lower peripheral surface, so that a "fixed" position occurs, when the pin has passed to one of the submerged positions according to fig. 1 and fig. 3. In order for the first detail to be able to be turned further in relation to the second detail 12, a significantly greater torque is initially required.

En låsing er oppnådd.A lock has been achieved.

Som det tydelig fremgår av fig. 1, 2 og 3 forandres ikke stil-lingen for den første konstruksjonsdetaljs sentrumsmarkerte hull i forhold til den ytre tapp når den første detalj dreies i forhold til den andre detalj til noen av de stillinger hvor en hurtiglåsingsvirkning oppnås, fig. 1 og fig. 3, eller til en mellomliggende dreiestilling uten hurtiglåsingseffekt, fig. 2. Dette beror på den første konstruksjonsdetaljs dreibare opphen-ging. Hvis den første detaljs ene ende 2 har en liten godstykkelse i forhold til diameteren for hullet med sentrumsmar-keringen 10, kan enden 2 rundt hullet ha en krave eller en flens 13 som kan strekke seg ut fra endens plan en avstand med samme størrelsesorden som hullets diameter. Den første detalj kan da være opphengt ved hjelp av en dreietapp 15 eller et lignende organ som strekker seg inn i hullet og langs kra-vens innside og er forbundet med den andre detalj. As is clear from fig. 1, 2 and 3, the position of the first construction detail's center-marked hole in relation to the outer pin does not change when the first detail is rotated in relation to the second detail to any of the positions where a quick locking effect is achieved, fig. 1 and fig. 3, or to an intermediate turning position without quick locking effect, fig. 2. This is due to the rotatable suspension of the first construction detail. If the first part's one end 2 has a small material thickness in relation to the diameter of the hole with the center marking 10, the end 2 around the hole can have a collar or a flange 13 which can extend from the end's plane a distance of the same order of magnitude as the hole's diameter. The first detail can then be suspended by means of a pivot pin 15 or a similar body which extends into the hole and along the inside of the collar and is connected to the second detail.

Som det tydelig fremgår av fig. 1 og 2 hviler den andre endeAs is clear from fig. 1 and 2 the other end rests

3 av den første detalj mot et underlag 14 såvel i den innfelte som i den utfelte dreiestilling. Forskjeller mellom disse stillinger bestemmes av forskjellene mellom nedsenkningenes stilling og er som tydelig vist på fig. 1 og 3 noe mindre enn en kvart omdreining. 3 of the first detail against a base 14 both in the recessed and in the unfolded pivot position. Differences between these positions are determined by the differences between the positions of the immersions and are, as clearly shown in fig. 1 and 3 somewhat less than a quarter of a turn.

Ved en godstykkelse på 2-3 mm for den ene ende 2 kan ringen ha en ytterdiameter på ca. 23,5 mm og en indre diameter på ca. With a material thickness of 2-3 mm for one end 2, the ring can have an outer diameter of approx. 23.5 mm and an inner diameter of approx.

21,1 mm. Derved kan den indre periferiflate ha en ytre diameter på ca. 19,9 mm, hullet en diameter på ca. 8,2 mm, flensen eller kraven en ytre diameter på ca. 112,2 mm, samt den første detal-jen kan ha en total lengde på ca. 55 mm. Den halvsirkelformede ring som da sitter sammen med resten av enden 2 bare ved sine to diametralt motsatte endepartier har herved en radiell tykkelse på ca. 2,4 mm. Nedsenkingene kan da ha en i det vesentlige plan bunn og plane sidevegger, idet sideveggene danner ca. 90°'s vinkel med hverandre. Den ytre tapp har da en i det vesentlige plan topp, hvis bredde er tilpasset til nedsenkingenes 5 og 6 bunnbredde og plane sidevegger hvis helning er tilpasset til nedsenkningens 5 og 6 sideveggers helning. 21.1 mm. Thereby, the inner peripheral surface can have an outer diameter of approx. 19.9 mm, the hole a diameter of approx. 8.2 mm, the flange or collar an outer diameter of approx. 112.2 mm, as well as the first detail can have a total length of approx. 55 mm. The semi-circular ring which then sits together with the rest of the end 2 only at its two diametrically opposite end parts has a radial thickness of approx. 2.4 mm. The immersions can then have an essentially flat bottom and flat side walls, with the side walls forming approx. 90° angle with each other. The outer pin then has an essentially flat top, the width of which is adapted to the bottom width of the immersions 5 and 6 and flat side walls whose slope is adapted to the inclination of the immersions 5 and 6 side walls.

Oppfinnelsen er selvfølgelig ikke begrenset til den på fig. viste utførelsesform, idet mange andre utførelsesformer er tenkelige. For eksempel behøver ringen 4 ikke utstrekke seg nøyaktig en halv omdreining rundt hullet, men det er tenkelig at den kan forløpe noe mer eller noe mindre enn en halv omdreining. I tillegg behøver ringen ikke ha bare to nedsenkinger, men det er tenkelig at det er anordnet flere enn to hvis mere enn to vinkelstillinger med hurtiglåsing er ønsket. Dreievin-kelen mellom to hurtigstillinger behøver ikke være nøyaktig en kvart omdreining, men kan såvel være noe større som noe mindre med hensyn til dreievinkel. The invention is of course not limited to that in fig. shown embodiment, many other embodiments being conceivable. For example, the ring 4 does not have to extend exactly half a turn around the hole, but it is conceivable that it may extend slightly more or slightly less than half a turn. In addition, the ring does not have to have only two recesses, but it is conceivable that more than two are arranged if more than two angular positions with quick locking are desired. The angle of rotation between two quick positions does not have to be exactly a quarter of a turn, but can be both slightly larger and slightly smaller with respect to the angle of rotation.
