Description

Foreliggende oppfinnelse angår en hev- og senkbar arbeidsanordning, f.eks. arbeidsbord. The present invention relates to a work device that can be raised and lowered, e.g. work table.

De fleste eksisterende arbeidsbord av denne art utmerkerMost existing work tables of this kind excel

seg ved en komplisert og følgelig sårbar og dyr konstruksjon. Hensikten med oppfinnelsen er å skaffe et konstruksjonsmessig enkelt, ' billig og pålitelig arbeidsbord hvis løfteanordning dessuten er lite plasskrevende. by a complicated and consequently vulnerable and expensive construction. The purpose of the invention is to provide a structurally simple, inexpensive and reliable work table whose lifting device also requires little space.

Denne hensikt oppnås ved at anordningen ifølge oppfinnelsen erkarakterisert vedto vertikale løfteben som styres på hvert sitt føringsben som i sin tur er festet ved en undre stativdel, samt ved et mellom den undre stativdel ogløfte-benehe virkende; symmetrisk leddsystem i hvis symmetripunkt en løftemotor, f. eks., en garasjedonkraft, angriper. This purpose is achieved in that the device according to the invention is characterized by two vertical lifting legs which are each controlled on their own guide legs which in turn are attached to a lower stand part, as well as by one acting between the lower stand part and the lifting leg; symmetrical joint system at whose point of symmetry a lifting motor, e.g., a garage jack, attacks.

Oppfinnelsen skal i det følgende beskrives nærmere-..under henvisning til vedlagte tegning som viser et hev- og senkbairt arbeidsbord i perspektivriss. The invention shall be described in more detail in the following -..with reference to the attached drawing which shows a raised and lowered work table in perspective view.

Bordet omfatter et stativ med en underdel som genereit er betegnet med 2 og en overdel som generelt er betegnet med 4. Underdelen omfatter en undre horisontal støttebjelke 6, hori-sontale benbjelker 8 som er festet ved støttebjeikens ender, og vertikale f ørings.b j eiker 10 som likeledes ér festet i nærheten av bjelkens 6 ender. Bjelken 6 bærer en løftemotor 12, f.eks. The table comprises a stand with a lower part which is generally denoted by 2 and an upper part which is generally denoted by 4. The lower part comprises a lower horizontal support beam 6, horizontal leg beams 8 which are attached at the ends of the support beam, and vertical guide beams. 10 which is also attached near the 6 ends of the beam. The beam 6 carries a lifting motor 12, e.g.

en konvensjonell hydraulisk garas j édonkraft, med løf.testempel 14 -og løftemånøverarm 16. Stemplet 14 eir beliggende midt mellom f øring.sb jelkene 10 og virker p-å et symmetrisk leddsystem. Leddsystemet omfatter to i det vesentlige opprettstående ledd a conventional hydraulic garage jack, with lifting piston 14 and lifting arm 16. The piston 14 is located in the middle between the guide beams 10 and works on a symmetrical joint system. The joint system comprises two essentially upright joints

18 som ved sine nedre ender er leddopplagret i bjelken 6; Ved sine øvre ender er leddene 18 leddforbundet med den ene ende av hver sin av to kryssende ledd 20. Stemplet 14 angriper ved et leddpunkt 22 ved leddenes 20 skjæringspunkt. Ved sine ytre ender bærer leddene 20 den øvre stativdel 4. Stativdelen 4 omfatter to vertikaie, • téleskopmessig på føringssterigéne forskyv-bare ben 24 som hår leddpunkter 26 for leddenes 20 øvre ender. Benene 24 er stivt innbyrdes forbundet ved hjelp av en tverr-bjelke 26 og bærer en bordplate 28. Bordplaten 28 er imidler-tid bare vist som eksempel og kan erstattes med passende an-ordninger av annen type som kan hå behov for stillbarhet i høyderetning. Senking av benene 24 skjer ved hjelp av et hånd-tak 30 som via en kabel 32 er forbundet, med en ikke vist ventil 18, which at its lower ends is joint supported in the beam 6; At their upper ends, the joints 18 are articulated with one end of each of two intersecting joints 20. The piston 14 engages at a joint point 22 at the intersection of the joints 20. At their outer ends, the joints 20 carry the upper stand part 4. The stand part 4 comprises two vertical, telescopic legs 24 which can be moved telescopically on the guiding sterigene as joint points 26 for the upper ends of the joints 20. The legs 24 are rigidly connected to each other by means of a cross beam 26 and carry a table top 28. The table top 28 is, however, only shown as an example and can be replaced with suitable arrangements of another type that may require height adjustment. Lowering of the legs 24 takes place by means of a handle 30 which is connected via a cable 32, with a valve not shown

på donkraften 12..on the jack 12..

Det.beskrevne leddsystem er eksakt symmetrisk beliggendeThe joint system described is exactly symmetrical

i forhold til donkraften 12 og benene 10, 24. Leddsystemet er. slik dimensjonert at benene 24 støter mot føringsbenenes 10 nedre festepunkter 34 når stemplet 14 er helt innskjøvet i sin sylinder. Stemplets .14 fra sylinderen maksimalt utskjøvne stilling motsvares på samme måte av bordets 28 høyest mulige nivå. in relation to the jack 12 and the legs 10, 24. The joint system is. so dimensioned that the legs 24 collide with the lower attachment points 34 of the guide legs 10 when the piston 14 is completely pushed into its cylinder. The piston's .14 maximum extended position from the cylinder corresponds in the same way to the table's 28 highest possible level.

Tverrbjelkene .8 bærer i hver ende hjul 36..The cross beams .8 carry wheels 36 at each end.

Ved 38 er vist støtte for.ikke viste skjermplater for At 38, support is shown for. screen plates are not shown for

leddsystemet.og løftemotoren.the joint system.and the lifting motor.

Ved" det beskrevne symmetriske leddar.rangement, som virker på. bare to ben, er kommodeskuffeffekten helt eliminert, samti-dig som et enkelt, pålitelig og lite plasskrevende l.øftearran-gement er oppnådd. With the symmetrical joint arrangement described, which acts on only two legs, the dresser drawer effect is completely eliminated, while a simple, reliable and space-saving lifting arrangement is achieved.

En kontinuerlig innstilling av stativets høyde er mulig og med det øvre håndtaket 30 kan en meget nøyaktig og følgelig eksakt innstilling oppnås etter at en grov■høydeinnstilling er foretatt ved hjelp av armen 16. A continuous adjustment of the stand's height is possible and with the upper handle 30 a very precise and consequently exact adjustment can be achieved after a rough height adjustment has been made using the arm 16.
