DK 162014 BDK 162014 B
Den foreliggende opfindelse angår en demonterbar stolebasis af den i krav l's indledning angivne art.The present invention relates to a removable chair base of the kind set forth in claim 1.
Der kendes en stolebasis med et midtersamlestykke og et antal 5 eger, der forløber radialt udad fra samlestykket, og som hver for enden bærer et hjul til at understøtte stolen på gulvet.There is known a chair base with a center assembly piece and a number of 5 spokes extending radially outward from the assembly piece, each carrying a wheel to support the chair on the floor.
Ved denne kendte stolebas iskonstruktion kan den søjle, der bærer stolesædet, være stift eller aftageligt fastgjort til samlestykket. På grund af den betydelige vægt, som stolebasi-10 sen skal bære, har egerne hidtil været formet i ét med eller været permanent fastgjort til samlestykket, således at stolebasisen med samlestykket og de radialt forløbende eger må lagres og transporteres som en enkelt samlet enhed.In this known chair base ice structure, the column supporting the chair seat may be rigid or detachably attached to the connector. Owing to the considerable weight that the chair base must carry, the spokes have hitherto been formed integrally or permanently attached to the connector so that the chair base with the connector and the radially extending spokes must be stored and transported as a single assembled unit.
15 Det er den foreliggende opfindelses formål at anvise en demonterbar stolebasis, der kan skilles i de enkelte komponenter for lagring og transport, og som hurtigt og nemt kan samles til dannelse af en stiv og stærk stolebasis på det sted, hvor den skal bruges, uden at der er behov for noget specielt værk-20 tøj eller nogen specielle evner.SUMMARY OF THE INVENTION It is an object of the present invention to provide a removable chair base which can be separated into individual components for storage and transport and which can be quickly and easily assembled to form a rigid and strong chair base in the place where it is to be used, without that there is a need for some special work-clothes or some special abilities.
For at tilgodese dette formål er den indledningsvist omtalte stolebasis ifølge den foreliggende opfindelse ejendommelig ved det i den kendetegnende del af krav 1 anførte.In order to meet this purpose, the initially mentioned chair base according to the present invention is characterized by the characterizing part of claim 1.
25 Når en eger er låst på plads i hver af fatningerne og stolesøjlen er sat på plads i samlestykket, vil en nedadrettet kraft, som virker på søjlen, f.eks. ved at en person sidder på stolen, blive overført gennem hver ege til forstarkningspla-30 den, der kan optage en større del af den belastning som udø ves. Som følge af hver eges indpasning i en tilhørende fatning og som følge af låsevirkningen opnået ved gevindenes samvirke, der klemmer pladen, hovedkroppen og egerne sammen, opnås en meget stiv og solid sammenkobling, som kan tåle betydelige 35 vægtpåvirkninger.When a spokes is locked in place in each of the sockets and the chair column is inserted into the connector, a downward force acting on the column, e.g. in that a person sitting on the chair is transferred through each oak to the reinforcing plate, which can take up a greater part of the load exerted. Due to the fit of each oak into a corresponding socket and due to the locking effect obtained by the co-operation of the threads clamping the plate, the main body and the spokes together, a very rigid and solid connection can be obtained which can withstand considerable weight effects.

3 I fig. 1 til 4 ses en stolebasis 10. Stolebasisen 10 omfatter et samlestykke 11 og et antal eger 12, der hver bærer en del til indgreb med gulvet og udformet som en møbelrulle eller et møbelhjul 13.3 In FIG. 1 to 4, a chair base 10 is seen. The chair base 10 comprises an assembly piece 11 and a plurality of spokes 12, each carrying a part for engaging the floor and formed as a furniture roll or a furniture wheel 13.
55
Samlestykket 11 kan være fremstillet af ethvert egnet materiale og i den i fig. 1 til 4 viste udførelsesform indbefatter den en hovedkrop 14 fremstillet som en sprøjtestøbedel af et stærkt, syntetisk plastmateriale, såsom nylon, og en stål-10 plade 15. Samlestykkets krop 14 er formet med en midterboring 16, der er tilspidset, så den kan optage en kendt stolbære-søjle 17. Søjlen kan være en ved gasvirkning højdeindstillelig søjle og kan monteres i boringen 16 ved friktionspasning. Samlestykkets krop 14 er også formet med fem ens og med lige 15 store vinkelmellemrum anbragte, radialt forløbende fatninger 18, hvori egerne 12 kan indsættes.The connector 11 may be made of any suitable material and in the embodiment shown in FIG. 1 to 4, it includes a main body 14 made as an injection molding member of a strong synthetic plastic material such as nylon and a steel 10 plate 15. The body 14 of the connector is shaped with a center bore 16 which is tapered to accommodate a known chair support column 17. The column can be a height adjustable column by gas action and can be mounted in the bore 16 by friction fitting. The body 14 of the connector is also formed with five identical and radially extending sockets 18 with equal 15 spaced apart spacers 18 into which the spokes 12 can be inserted.
Hver eger 12 er fremstillet af pladestål og har en rørform med et i det væsentlige rektangulært tværsnit. Hver af egerne 12's 20 dimensioner er sådan, at dens indre ende er i tæt skubbepasning med den pågældende fatning 18's hul.Each spokes 12 is made of sheet steel and has a tubular shape of a substantially rectangular cross-section. Each of the 20 dimensions of the spokes 12 is such that its inner end is in close push fit with the hole of the respective socket 18.
Den ydre ende af hver eger 12 er lukket af en rørendeindsats 19, der kan være en støbedel af plast. Hver indsats 19 har et 25 hovedlegeme 20, der med tæt pasning er indsat i rørets ende, og en endeflange 21, der ligger an mod rørets ende. Indsatsen 19's legeme 20 er formet med en boring 22, der flugter med et hul 23 i egeren 12's bundvæg nabostillet til egerens ende.The outer end of each spokes 12 is closed by a touching insert 19 which may be a plastic molding member. Each insert 19 has a main body 20, which is snugly inserted into the end of the tube, and an end flange 21 abutting the end of the tube. The body 20 of the insert 19 is formed with a bore 22 which aligns with a hole 23 in the bottom wall of the spokes 12 adjacent to the spokes end.
Hvert hjul 13 har en kendt lodret akseltap 24, der er ført 30 gennem hullet 23 i egeren ind i indsatsens boring 22, hvor den fastholdes ved friktionsindgreb udøvet på akseltappen 24 af indsatsens plastmateriale.Each wheel 13 has a known vertical shaft pin 24 which is guided 30 through the hole 23 in the spoke into the bore 22 of the insert, where it is held by friction engagement exerted on the shaft pin 24 by the plastic material of the insert.
For at samle en eger 12 med samlestykket 11 skubbes egeren 35 12's indre ende helt ind i fatningen 18, således at denne egerende ligger an imod fatningens endevæg 25. I denne stilling flugter et skrueoptagende hul 26 i egerens bundvæg med etTo assemble a spokes 12 with the connector 11, the inner end of the spokes 35 12 is pushed all the way into the socket 18 so that this spokes abuts against the end wall 25. In this position, a screw receiving hole 26 in the spokes bottom wall flushes with a

4 hul 27 i fatningen 18's bundvæg. Når egerne er i position, placeres stålpladen 15 mod bunden af samlestykkets krop 14, hvor det placeres i stilling ved hjælp af en læbe 28 på samle-stykkets krop.4 hole 27 in the bottom wall of the socket 18. When the spokes are in position, the steel plate 15 is positioned against the bottom of the body piece 14, where it is positioned by a lip 28 on the body of the body piece.
55
Stålpladen 15 er formet med et antal huller 29, der kan flugte med hullerne 27 i kroppen 14. Med hullerne 29 i pladen flugtende med hullerne 27 i kroppen 14 kan en skrue føres gennem hvert flugtende hulpar 29 og 27 og skrues ind i det skruemod-10 tagende hul 26 i egeren 12, således at hver eger låses i sin tilhørende fatning.The steel plate 15 is formed with a plurality of holes 29 which can align with the holes 27 in the body 14. With the holes 29 in the plate flush with the holes 27 in the body 14, a screw can be passed through each flushing pair of holes 29 and 27 and screwed into the screw mode. 10, taking hole 26 in the spokes 12 so that each spokes locks in its associated socket.
Når en eger er blevet låst på plads i hver af de fem fatninger 18, og søjlen 17 er indsat i samlestykket, vil en nedadrettet 15 kraft udøvet på søjeln 17, f.eks. af en person, der sidder på stolen, overføres gennem hver eger til stålpladen 15, der vil bære en større del af den på samlestykket og egerne udøvede belastning. Takket være hver egers tætte pasning i den tilhørende fatning 18 og låsevirkningen fra skruen 30, der klemmer 20 stålpladen, samlestykkets krop og egeren sammen, opnår man en meget stiv og solid sammenkobling, der kan tåle meget betydelige vægtpåvirkninger.When a spokes has been locked in place in each of the five sockets 18 and the column 17 is inserted into the connector, a downward force 15 will be exerted on the column 17, e.g. of a person sitting on the chair is transmitted through each spokes to the steel plate 15 which will carry a greater portion of the load exerted on the connector and spokes. Thanks to the close fit of each spokes in the associated socket 18 and the locking action of the screw 30, which squeezes the steel plate, the body of the connector and the spokes together, a very rigid and solid connection can be obtained which can withstand very significant weight effects.
Det ses, at stolebasisen 10's komponenter omfattende samle-25 stykket 11, egerne 12 og stolehjulene 13 kan emballeres og transporteres i de monteret tilstand med omtrent 1/4 af den plads, der kræves for den samlede stol, hvilket giver væsentlige transport- og lagerbesparelser. Komponenterne kan så samles på brugsstedet med et minimalt tidsforbrug og en mini-30 mal arbejdsindsats ved simpelthen at stikke egerene i samlestykket, placere pladen på plads, indsætte og skrue skruerne i bund og så samle rørendeindsatsene og stolehjulene på plads. Stolebasisen 10 er så helt samlet og klar til at optage søjlen 17.It is seen that the components of the chair base 10 comprising the assembly piece 11, the spokes 12 and the chair wheels 13 can be packaged and transported in the assembled condition with about 1/4 of the space required for the total chair, which provides significant transport and storage savings. . The components can then be assembled at the point of use with minimal time and minimal work effort by simply inserting the spokes into the connector, placing the plate in place, inserting and unscrewing the screws and then assembling the stirrups and chair wheels in place. The chair base 10 is then completely assembled and ready to receive the column 17.

5 stålplade 31 med en perifer læbe 32, der placeres i en spalte 33 formet i hver eger 34. Som det fremgår af fig. 8, skråner egerspalten 33's endeflade 35, der er i indgreb med stålpladens læbe 32, under en vinkel på ca. 12° i forhold til lodret, 5 således at læben 32 udøver en kilevirkning på egeren 34 og tvinger egeren imod endevæggen af den muffe, hvori den er placeret. Tilvejebringelsen af en læbe forbedrer følgelig opnåelsen af en solid og fast forbindelse mellem samlestykke og eger.5 shows steel plate 31 with a peripheral lip 32 placed in a slot 33 formed in each spokes 34. As can be seen in FIG. 8, the end surface 35 of the spokes 33, which engages the lip 32 of the steel plate, slopes at an angle of approx. 12 in relation to the vertical, 5 such that the lip 32 exerts a wedge effect on the spokes 34 and forces the spokes against the end wall of the sleeve in which it is located. Accordingly, the provision of a lip improves the attainment of a solid and firm connection between the connector and the spokes.
