Abstract

An arrangement related to furniture legs, in particular legs of chairs, for reducing scraping sounds arising from vibrations between the leg and the support - the floor - and comprising a vibration-damping elastic body 16 arranged at the end of the leg and provided with a friction-reducing coating. The object is to provide an arrangement having a high vibration-damping effect, and at the same time reducing friction between the piece of furniture and the floor. This has been achieved by the vibration-damping body 16 compressing so much when subjected to an external load acting on the piece of furniture that the coating 17 becomes situated within a cutout 15 in the shoe 12, which is formed with an abutment surface 13 surrounding the body 16 and the coating 17 and designed as an abutment surface against the floor. <IMAGE>

Description

8106655-2 förslitning. 8106655-2 wear.

Uggfinningens ändamål gch viktigaste käggetggken Ändamålet med föreliggande uppfinning år att åstadkomma en anordning, speciellt för stolsben, som uppvisar mycket goda vibrationsdämpande och därmed ljuddämpande effekt och vars friktionsminskande beläggning är så arrangerad att den även under ogynnsamma betingelser. dvs. när stolen under belastning skjutes längs golvet har mycket stor livslängd. Dessa uppgifter har lösts genom att den vibrationshämmande kroppen under inverkan av en på möbeln verkande extern belastning är komprimerbar så mycket att beläggningen kommer att bli belägen inuti en urtagning i foten. vilken är utformad med en kroppen och beläggningen omgivande anliggningsyta utformad som kontaktyta mot golvet.The object of the present invention and the most important cogwheel teeth is The object of the present invention is to provide a device, especially for chair legs, which exhibits very good vibration-damping and thus sound-damping effect and whose friction-reducing coating is so arranged that even under unfavorable conditions. i.e. when the chair under load is pushed along the floor has a very long service life. These data have been solved in that the vibration-inhibiting body, under the influence of an external load acting on the furniture, is compressible so much that the coating will be located inside a recess in the foot. which is formed with a contact surface surrounding the body and the coating designed as a contact surface against the floor.

Beskrivning av ritningar Figurerna 1-4 visar fyra olika utföringsformer av anordningen enligt uppfinningen i snitt. ßgskrivninq av utförindsexempgl Pâ ritningen betecknar 11 nedre delen av ett möbelben, exempelvis ett stolsben. och med 12 en benets nedre ände omslutande fot. Vid utföringsformen enligt fig. 1 har foten försetts med en relativt bred bas eller anliggningsyta 13 mot golvet samt en urtagning 14 i vilken benet 11 är inskjutbart.Description of drawings Figures 1-4 show four different embodiments of the device according to the invention in section. Description of Embodiment In the drawing, 11 denotes the lower part of a furniture leg, for example a chair leg. and with 12 the lower end of the leg enclosing the foot. In the embodiment according to Fig. 1, the foot has been provided with a relatively wide base or abutment surface 13 against the floor and a recess 14 in which the leg 11 is slidable.

I Fotens nedre del är anordnat en mot kontaktytan 13 öppen urtagning 15 i vilken en vibrationshämmande. elastisk kropp 16 av t.ex. gummi år placerad. Vid gummikroppens 16 undersida är fäst en friktionsminskande beläggning 17, exempelvis ett filtstycke. Kroppen 15 år så dimensionerad att om stolen belastas kommer gummikroppen 16 att komprimeras så mycket att filtstycket 17 blir beläget innanför urtagningen 15.In the lower part of the foot is arranged a recess 15 open towards the contact surface 13 in which a vibration-inhibiting. elastic body 16 of e.g. rubber year placed. Attached to the underside of the rubber body 16 is a friction-reducing coating 17, for example a felt piece. The body 15 is so dimensioned that if the chair is loaded, the rubber body 16 will be compressed so much that the felt piece 17 will be located inside the recess 15.

Foten 12 framställes av ett 7'plastmaterial med låg friktionskoefficient, exempelvis något av de plastmaterial som 8106653-2 finns under handelsnamnet Delrin, nylon el.likn. Den hylsformade foten 12 avsmalnar i riktning mot sin övre ände samtidigt som hâligheten 14 kring stolsbenets nedre ände är något större än benets tvärsnitt, varigenom stolsbenet kan utföra vissa begränsade rörelser i Förhållande till Foten 12.The foot 12 is made of a 7 'plastic material with a low coefficient of friction, for example some of the plastic materials which 8106653-2 are under the trade name Delrin, nylon or the like. The sleeve-shaped foot 12 tapers towards its upper end while the cavity 14 around the lower end of the chair leg is slightly larger than the cross section of the leg, whereby the chair leg can perform certain limited movements in relation to the foot 12.

Utföringsexemplet enligt fig. 2 skiljer sig från föregående genom att benet 11 verkar direkt på gummikroppen 15 via en tryckfördelningsskiva 18. För att begränsa benets 11 axiella rörelse och därmed gummikroppens 16 sammanpressningsgrad, samverkar tryckplattan 18 med en ansats 19 i utrymmet 14. Vid möbelns belastning kommer således beläggningen 1? att pressas in i foten samtidigt som benet från motsatta hållet sammanpressar gummikroppen 15 tills tryckfördelningsplattan 18 vilar mot ansatsen 19, varigenom belastningen även överföras till Foten 12 som pressas till anliggning mot golvet.The exemplary embodiment according to Fig. 2 differs from the previous one in that the leg 11 acts directly on the rubber body 15 via a pressure distribution plate 18. To limit the axial movement of the leg 11 and thus the degree of compression of the rubber body 16, the pressure plate 18 cooperates with a shoulder 19 in the space 14. thus will the coating 1? to be pressed into the foot at the same time as the leg from the opposite direction compresses the rubber body 15 until the pressure distribution plate 18 rests against the shoulder 19, whereby the load is also transferred to the foot 12 which is pressed to abut against the floor.

Vid utföringsformen enligt Fig. 3, som principiellt är lik utföringsexemplet enligt fig. 2. år utrymmet 14 fyllt med en relativt mjuk gummimassa 20. som ger benet 11 en viss styrning i sidled, men samtidigt tillåter benet att utföra de nödvändiga sidorörelserna som uppkommer genom vibrationer när benet drages över golvet.In the embodiment according to Fig. 3, which is in principle similar to the embodiment according to Fig. 2, the space 14 is filled with a relatively soft rubber mass 20. which gives the leg 11 a certain lateral control, but at the same time allows the leg to perform the necessary lateral movements resulting from vibrations when the leg is pulled across the floor.

I det visade utföringsexemplet är Foten 12 tvådelad. vilket underlättar anbringandet av gummikroppen 16. som För övrigt kan vara en integrerad enhet med filtstycket 17 och Fördelningsplattan 15. vid utföringsexemplet enligt fig. 4 är foten 12 utformad att dels omsluta benets nedre ände och att dels samverka med en central styrtapp 21 i rörbenets 11 inre. Benets 11 ände vilar pa en ringformad gummikropp 1Sa, som är skild Från gummikroppen 16b vid vilken filtstycket 17 är anbragt.In the exemplary embodiment shown, the foot 12 is two-part. which facilitates the application of the rubber body 16. which can otherwise be an integrated unit with the felt piece 17 and the distribution plate 15. in the exemplary embodiment according to Fig. 4, the foot 12 is designed to enclose the lower end of the leg and to cooperate with a central guide pin 21 in the tube leg 11. internal. The end of the leg 11 rests on an annular rubber body 1Sa, which is separate from the rubber body 16b at which the felt piece 17 is arranged.

Kring övre delen av styrtappen 21 är anordnad. exempelvis fastvulkad. en mjuk gummiring 22, som tillåter benet att utföra begränsade rörelser i foten samtidigt som vibrationsrörelser från Foten icke överföras den vägen. 8106653-2 Utförda; jämförande skrapljudtester har visat. att en stålrörsstol av konventionell konstruktion och av det slag som användes i stor utsträckning i grundskolan och gymnasium, och som är försedd med konventionella plasttassar, samt en likadan stol försedd med anordningen enligt uppfinningen har skrapljudet kunnat reduceras från i genomsnitt 65 DBA till i genomsnitt LU DBA.Around the upper part of the guide pin 21 is arranged. for example, solidified. a soft rubber ring 22, which allows the leg to perform limited movements in the foot while not transmitting vibrational movements from the foot that way. 8106653-2 Performed; comparative scratch sound tests have shown. that a tubular steel chair of conventional construction and of the kind used extensively in primary and secondary school, and which is provided with conventional plastic paws, and a similar chair provided with the device according to the invention, the scratching noise has been reduced from an average of 65 DBA to an average LU DBA.

Uppfinningen är icke begränsad till de visade och beskrivna utföringsformerna utan ett flertal variationer år tänkbara inom ramen för patentkraven. Således är det möjligt att kombinera i en utföringsvariant visade kännetecken med någon eller de övriga av utföringsexemplen.The invention is not limited to the embodiments shown and described, but a number of variations are conceivable within the scope of the claims. Thus, it is possible to combine features shown in an embodiment variant with one or the other of the embodiments.
