Description
Anordning ved dørvrider. Device for doorknobs.
Nærværende oppfinnelse vedrører en The present invention relates to a
dørvrider av den type som består av en firkantbolt som strekker seg gjennom låsekassen og dørbladet og på hvis fremskyt-ende ender der er påtredd og festet en hylseformet indre del av dørvriderhåndtak-ene. I befestigelsen inngår da fjærende inngrepsorgan som er slik anordnet at de tillater håndtakenes innskyvning i retning mot låsekassen, men motsetter seg beveg-else i den motsatte retning. door twister of the type which consists of a square bolt which extends through the lock box and the door leaf and on whose projecting ends a sleeve-shaped inner part of the door twister handles is applied and fixed. The fastening then includes spring-loaded engagement means which are arranged in such a way that they allow the handles to be pushed in towards the lock box, but oppose movement in the opposite direction.
I den ytre ende er denne befestigelses-hylse fortrinnsvis forsynt med et mutterhode eller annen passende utformning slik at befestigelseshylsen kan dreies i forhold til dørhåndtaket ved påsetning av hensiktsmessig verktøy. Denne anordning av befestigelseshylsen er særlig hensiktsmessig når fjærstålskiven — slik som videre foreslåes ifølge nærværende oppfinnelse — utformes slik at den i hviletilstand er krummet. Ved innspenningen vil krumnin-gen måtte rettes ut slik at skiven blir plan og dens tenner vil derved gripe inn i firkantbolten. Når innspenningen derved løs-nes, vil skiven igjen innta sin buede form, og tanninngrepet mer eller mindre opp-heves. At the outer end, this fastening sleeve is preferably provided with a nut head or other suitable design so that the fastening sleeve can be rotated in relation to the door handle by fitting a suitable tool. This arrangement of the fastening sleeve is particularly appropriate when the spring steel disc — as further proposed according to the present invention — is designed so that it is curved in its rest state. During clamping, the curvature will have to be straightened so that the disc becomes flat and its teeth will thereby engage in the square bolt. When the clamping is thereby released, the disc will again assume its curved shape, and the tooth engagement is more or less raised.
Til bedre forståelse av oppfinnelsen skal nedenfor beskrives et utførelseseksem-pel vist på tegningen. Fig. 1 viser et aksialt snitt gjennom den indre ende av det ene dørhåndtak inn-festet ved en anordning ifølge oppfinnelsen. Fig. 2 viser fjærstålskiven sett i plan. Fig. 3 viser skiven sett i tverrsnitt etter linjen III—III i fig. 2, henholdsvis i hvile-stilling A og i innspent stilling B. For a better understanding of the invention, an embodiment shown in the drawing will be described below. Fig. 1 shows an axial section through the inner end of one door handle attached by a device according to the invention. Fig. 2 shows the spring steel disc seen in plan. Fig. 3 shows the disk seen in cross-section along the line III—III in fig. 2, respectively in rest position A and in clamped position B.
Med 1 er betegnet døren. Rundt dør-vrideranordningen kan der om ønskes være anbragt et dørskilt 2. Dørhåndtakets hylsedel 3 omslutter firkanttappen 4 på kjent måte. Med den indre ende av hylsedelen 3 for dørhåndtaket er der så anbragt en fjærstålskive 6 med en sentral åpning 8 for bolten 4 og et hensiktsmessig antall tenner 7 rettet innover mot nevnte åpning 8. Fjærstålskiven 6 er utformet slik at den i hviletilstand har en buet profil slik som vist i fig. 3A. The door is denoted by 1. If desired, a door sign 2 can be placed around the door-turning device. The sleeve part 3 of the door handle encloses the square pin 4 in a known manner. With the inner end of the sleeve part 3 for the door handle, a spring steel disc 6 is then arranged with a central opening 8 for the bolt 4 and an appropriate number of teeth 7 directed inwards towards said opening 8. The spring steel disc 6 is designed so that it has a curved profile in its resting state as shown in fig. 3A.
For fastholdelse av fjærstålskiven ved enden av dørhåndtakets hylsedel 3 er der anordnet en hylsemutter 9, pågjenget dør-håndtaksdelen 3 og i den indre ende forsynt med et ombøyet parti eller flens 10 samt i den ytre ende 12 forsynt med et mutterhode. Når hylsemutteren 9 trekkes til på delen 3 vil den i det derved tilveiebragte ringrom anbragte f jærstålskive 6 innspen-nes mot enden av dørhåndtakhylsen 3. Ved tiltrekning av mutteren 9, 12 vil fjærstålskiven 6 måtte rette seg ut slik som vist i fig. 3 B. Derved vil tennene 7 gripe ytter-ligere fatt i omkretsen av firkantbolten. To retain the spring steel washer at the end of the door handle's sleeve part 3, a sleeve nut 9 is arranged, threaded onto the door handle part 3 and provided at the inner end with a bent part or flange 10 and at the outer end 12 provided with a nut head. When the sleeve nut 9 is tightened on the part 3, the spring steel disc 6 placed in the annulus thus provided will be clamped against the end of the door handle sleeve 3. When the nut 9, 12 is tightened, the spring steel disc 6 will have to straighten as shown in fig. 3 B. Thereby, the teeth 7 will grip the circumference of the square bolt further.
Hvis imidlertid innspenningen løsnes f. eks. ved påsetting av en nøkkel på mutterhode 12 og dreining av dette i forhold til håndtaket 3, vil fjærstålskiven 6 igjen innta sin buede form, hvorved tanninngrepet med hylsedelen vil mer eller mindre løsnes slik at håndtaket kan trekkes av firkantbolten 4. If, however, the clamping is loosened, e.g. by placing a key on the nut head 12 and turning this in relation to the handle 3, the spring steel washer 6 will again assume its curved shape, whereby the tooth engagement with the sleeve part will more or less loosen so that the handle can be pulled off the square bolt 4.
