Description
Anordning ved stolskallDevice for chair shell
Oppfinnelsen angår en anordning ved et stolskall av p.1 ast eller liknende som ei tilpasset for montering på et understell, hvor stolskallet omfatter en setedel og en ryggdel som er fremstilt: i ett stykke og på sidene bar avstivende vanger. The invention relates to a device for a chair shell of p.1 ast or similar that is adapted for mounting on a frame, where the chair shell comprises a seat part and a back part which are produced: in one piece and on the sides bare stiffening ribs.
I forbindelse med montering av sådanne stolskall på til-borende rdrverk som utgjor bærende enhet eller understell for stolen, er det kjent å feste stolskallet ved hjelp av låsbare klips eller skruer som eventuelt kan være selvgjengende. En ulempe ved benyttelse av skruer for befestigelse er imidlertid at disse under brui; sier ut- In connection with the assembly of such chair shells on the attached wheelwork which forms the supporting unit or underframe for the chair, it is known to fasten the chair shell by means of lockable clips or screws which may possibly be self-tapping. However, a disadvantage of using screws for fastening is that these break during says out-
seg ut eller er utséit t for brekas le ■ Ved denne f es ternet ode kreves dessuten benyttelse av spesielt verktov oe monteringen blir forholdsvis tidkrevende. stand out or is suitable for breaking ■ In addition, this type of suspension requires the use of special tools and assembly is relatively time-consuming.
Det er i denne forbindelse også. kjent å benytte sneppert-montasje, noe som gir færre komponenter og dessuten sikrere festean-ordning. Andre fordeler ved sneppertbefest i geise er at monteringen kan skje uten benyttelse av verktoy og med mindre monteringsarbeide. Ved en kjent anordning er festeklosser for snepperttilkopling anordnet under stolskallets setedel. Når stolskallet er fremstilt av press-stopt plast, forer imidlertid sådanne festeklosser til dannelse av såkalte synkemerker under fremstillingen. For at. stolskallets sta-bilitet og befestigelsen skal være tilfredsstillende, må videre kreftene fra sneppertbefestigelsen overfores til vangene når stolskallets ryggdel er belastet, altså når ryggdelen belastes av en person som sitter på stolen. Denne kjente lbsning innebærer således at man enten må benytte forholdsvis stor godsmengde for å oppnå tilstrekkelig styr-ke for kraftoverfdring, eller det må røre anordnet stotteribber som er forbundet med vangene. It is in this connection as well. known to use snap-on assembly, which results in fewer components and also a more secure attachment arrangement. Other advantages of snappert fastening in geyser are that the assembly can take place without the use of tools and with less assembly work. With a known device, fastening blocks for snapper connection are arranged under the seat part of the chair shell. When the chair shell is made of press-stopped plastic, however, such fastening blocks lead to the formation of so-called sink marks during manufacture. So that. the stability of the chair shell and the attachment must be satisfactory, the forces from the snap fastening must also be transferred to the legs when the back part of the chair shell is loaded, i.e. when the back part is loaded by a person sitting on the chair. This known loading thus means that one must either use a relatively large quantity of goods in order to achieve sufficient strength for power transmission, or it must touch arranged support ribs which are connected to the vanes.
Det er et formål med oppfinnelsen å tilveiebringe en stol--skallkonstruksjon med festeanordninger som gir stabilt feste og effek-tiv opptagelse av belastende krefter. Andre formål er å tilveiebringe et stolskall som er velegnet for stabl ing og dermed muliggjor billig transport og forsendelse av stolskall og rorverk hver for seg, sam-tidig som festeanordningen gir meget lettvint og rask montering av stolskall og understell, slik at monteringsutgiftene reduseres tii et minimum. It is an aim of the invention to provide a chair-shell construction with fastening devices which provide stable fastening and effective absorption of burdensome forces. Another purpose is to provide a chair shell that is suitable for stacking and thus enables cheap transport and dispatch of the chair shell and steering gear separately, at the same time that the fastening device provides very easy and quick assembly of the chair shell and underframe, so that the assembly costs are reduced in a minimum.
De nevnte formål oppnås ved et stolskall av den innlednings-vis angitte type som ifolge oppfinnelsen er kjennetegnet ved at innskjæringer for opptagelse med sneppert virkning av festede Ler på understellet er anordnet i stolskallets sidevanger.. The aforementioned purposes are achieved by a chair shell of the type indicated at the outset which, according to the invention, is characterized by the fact that incisions for the reception with a snapping effect of fixed clay on the underframe are arranged in the side walls of the chair shell.
En vesentlig egenskap ved stolskallet ifolge oppfinnelsen er at sneppertfestene er anordnet på de steder hvor kreftene må opptas ved belastning av stolryggen. Dette innebærer at man i forhold til den kjente teknikk oppnår' mer solid og stivere konstruksjon med an-vendelse av samme materialmengde og kvalitet.. An essential feature of the chair shell according to the invention is that the snap fasteners are arranged in the places where the forces must be absorbed when the chair back is loaded. This means that compared to the known technique, a more solid and stiffer construction is achieved using the same quantity and quality of material.
Oppfinnelsen skal beskrives nærmere i det folgende under henvisning til tegningen, der fig. 1 viser et sni ttbiide, sett fra siden, av et stolskall med en utforelse av festearrangementet ifolge oppfinnelsen, og fig. 2 viser den ene halvdel 'av stolskallet på fig. The invention shall be described in more detail in the following with reference to the drawing, where fig. 1 shows a section, seen from the side, of a chair shell with an embodiment of the fastening arrangement according to the invention, and fig. 2 shows one half of the chair shell in fig.
1, sett ovenfra..1, seen from above..
Slik det fremgår av tegningen, omfatter det viste stolskall 1 en setedel 2 og en i ett stykke med setedelen fremstilt ryggdel 3-Det benyttede materiale er fortrinnsvis en passende plast, såsom poly-propylen, A.B.S. (akrylnitrilbutadienstyren) , polyamid eller liknende., Materialtykkelsen fremgår av de på tegningen viste snitt. De på frg. As can be seen from the drawing, the chair shell 1 shown comprises a seat part 2 and a back part produced in one piece with the seat part 3 - The material used is preferably a suitable plastic, such as polypropylene, A.B.S. (acrylonitrile butadiene styrene), polyamide or similar., The material thickness can be seen from the sections shown in the drawing. Those on frg.
2 viste snitt illustrerer setedelens 1 form og orienteringen av de The section shown in 2 illustrates the shape of the seat part 1 and its orientation
avstivende sidevanger 4 i forhold til setedelen. Som vist er setedelens vanger 4 sammenhengende med avstivende vanger 5 på ryggdelen 3. stiffening side rails 4 in relation to the seat part. As shown, the seat part's legs 4 are continuous with stiffening legs 5 on the back part 3.
Hver av setedelens vanger er forsynt med innskjæringer eller spor for sneppertopptagelse av passende festedeler på et understell (ikke vist) som f.eks. kan være laget av passende stålror. I den viste utforelse består innskjæringene av et fremre spor 6 og et bakre spor 7 med innfciringsåpninger som munner ut ved sidevangens underkant. Den kant av det bakre spor 7 som ligger nærmest det fremre spor 6, er utformet med en nese 8 som bevirker sneppertfastspenning til stolskallet av en festede], på understellet når en annen, s^^.marbei-dende festedel forst er fort på plass i det fremre spor. Dette ar-rangement sikrer stabil fastspenning og dessuten lettvint montering ved at ryggdelen boyes eller presses noe bakover ved den avsluttende montasje når vedkommende festedel innfores i det bakre spor. Under belastning blir vedkommende festedel presset mot nesepartiet 8, slik Each of the sides of the seat part is provided with notches or grooves for snap-on mounting of suitable fastening parts on a base (not shown) such as e.g. can be made of suitable steel rudder. In the embodiment shown, the incisions consist of a front groove 6 and a rear groove 7 with insertion openings that open out at the lower edge of the sidewall. The edge of the rear track 7 which is closest to the front track 6 is designed with a nose 8 which causes snapping to the chair shell by a fixed], on the chassis when another, s^^.marbing fixing part is first quickly in place in the front track. This arrangement ensures stable clamping and, moreover, easy assembly by bending or pushing the back part slightly backwards during the final assembly when the fastening part in question is inserted into the rear groove. Under load, the fastening part in question is pressed against the nose part 8, as follows
at understellfestedelen blir stabilt fastholdt i sporet 7. For å that the undercarriage attachment part is stably held in the groove 7. In order to
sikre,fastholdelse av festedelen som anbringes i sporet 6 under den innledende monteringsfase, bar dette spor fortrinnsvis en slik form at festedelen fastholdes med sneppertvirkning i sporet. ensure retention of the fastening part which is placed in the groove 6 during the initial assembly phase, this groove preferably has such a shape that the fastening part is retained with a snap action in the groove.
For at stolskallet ikke skal være for tett under bruk, er en åpning 9 anordnet/i den nedre del av ryggdelen 3. In order for the chair shell not to be too tight during use, an opening 9 is arranged/in the lower part of the back part 3.
Vangene 4 og 5 er vist å ha i hovedsaken samme tykkelse som stolskallets setedel og ryggdel, roen vangene kan selvsagt være tykkere, avhengig av de aktuelle styrkekrav. The legs 4 and 5 are shown to have essentially the same thickness as the seat and back part of the chair shell, although the legs can of course be thicker, depending on the current strength requirements.
Man vil innse at utformningen og anbringelsen av innskjam-ringene eller sporene for sneppertbefestigelse kan varieres på mange forskjellige måter-, idet det. vesentlige er at, sporene er anordnet i s i de van gene•p å de steder hvor de virkende krefter må opptas ved be-. lastning av stolen og sar: li g dennes ryggdel. It will be realized that the design and placement of the in-frame rings or slots for snappert attachment can be varied in many different ways, since that. essential is that, the tracks are arranged in s in the van gene•p in the places where the acting forces must be taken up by be-. loading the chair and sar: li g its back part.
