SIDDE/STÅBORDSEAT / stand table

Frembringelsens anvendelsesområdeScope of production

Denne frembringelse angår et sidde/ståbord med et basiselement til anbringelse på et underlag og en platform, et mellem basiselementet og platformen anbragt og i højden vari-erbart saksestativ, der består af et første ben og et andet ben, som er indbyrdes hængslet ved deres midte, hvor benenes ene ende er hængslet ved platformen henholdsvis ved basiselementet, og deres anden ende er forskydbart lejret ved basiselementet henholdsvis ved platformen, samt et drivaggregat til hævning og sænkning af sidde/ståbordets platform ved ændring af benenes indbyrdes vinkel.This arrangement relates to a sitting / standing table with a base element for mounting on a support and a platform, a space between the base element and the platform, and a height-adjustable scissor stand consisting of a first leg and a second leg, which are mutually hinged at their a center where the one end of the legs is hinged at the platform or base element, and their other end is slidably mounted at the base element and platform, respectively, and a drive assembly for raising and lowering the platform / seating platform by changing the angle of the legs.

Sidde/ståborde af denne art er udviklet til arbejdspladser, hvor højdejustering af bordplade eller arbejdsområde er hensigtsmæssig ved arbejdssituationen.Sitting / standing tables of this kind are designed for workplaces where height adjustment of countertop or work area is appropriate in the work situation.

Begrebet arbejdspladser skal forstås i bred forstand og omfatter for eksempel skriveborde, der skal bruges som sidde/stå bord, hvor der kan være et ønske om højdejuste-ring fra 65 til 125 cm.The concept of workplaces must be understood in a broad sense and includes, for example, desks that should be used as sitting / standing tables where there may be a desire for height adjustment from 65 to 125 cm.

Der kan også være tale om montagepladser, svejseborde og pakkeborde, der skal benyttes af skiftende operatører eller skal bruges under et monteringsarbejde, hvor der er behov for en højdejustering under monteringsarbejdet.There may also be mounting places, welding tables and packing tables to be used by changing operators or to be used during assembly work where a height adjustment is required during assembly work.

Udtrykket platform skal også tages i bred forstand og kan således omfatte egentlige bordplader og stativer, der er udformet til at understøtte emner, der skal bearbejdes og/eller monteres.The term platform should also be taken in a broad sense and thus may include actual countertops and racks designed to support items to be machined and / or assembled.

Kendt teknikPrior art

Sidde/ståborde af denne art er kendt fra for eksempel FR offentliggørelsesskrift nr. 2 637 165, US patentskrift nr. 5 400 720 og SE patentansøgnincr nr. 9200511-5.Seating / standing tables of this kind are known from, for example, FR Publication No. 2,637,165, U.S. Patent No. 5,400,720, and SE Patent Application No. 9200511-5.

Det tekniske problem, der skal løsesThe technical problem to be solved

De kendte sidde/ståborde er noget uhensigtsmæssige i brug, da bordpladen og eventuel last let kan bringe sidde/ståbor-det i ubalance, idet tyngdepunktet forskydes under højdeindstillingen. Endvidere synes tværsarg og ben at komme i vejen, idet der er et stativ i hver side af de kendte borde. Endelig er udformningen og anbringelsen af drivaggregatet ikke hensigtsmæssig, da der til højdejusteringen kræves store kræfter. Ved kendte sidde/ståborde bevæges bordpladen ikke lodret op og ned, hvorfor der ved sådanne borde, der stilles mod hinanden, kan opstå et gab mellem bordpladerne, når der sker en justering af højden.The known sitting / standing tables are somewhat inconvenient in use, as the countertop and any load can easily put the sitting / standing table in unbalance as the center of gravity is shifted during the height adjustment. Furthermore, cross-legs and legs appear to get in the way, with a stand on each side of the known tables. Finally, the design and arrangement of the drive unit is not appropriate, as high forces are required for the height adjustment. In the case of known sitting / standing tables, the table top does not move vertically up and down, which is why at such tables that are set against each other, a gap may occur between the table tops when adjusting the height.

Med frembringelsen ønskes der tilvejebragt en forbedret type af sidde/ståbord, som ikke kan bringes i ubalance, hvor det skal være nemmere at indstille bordets højde uanset den foreliggende vaegtbelastning, og hvor stativet ikke er i vejen under brugen.With the creation, it is desired to provide an improved type of sitting / standing table which cannot be imbalanced, where it should be easier to adjust the height of the table regardless of the present weight and where the rack is not in use during use.

Den nye teknikThe new technique

Det nye ved frembringelsen udgøres af, at saksestativet efter valg er anbragt variabelt under sidde/ståbordets platform, at drivaggregatet omfatter et vægtudligningsorgan og et låseorgan, der begge ved deres ene ende er lejret til basiselementet, at vægtudligningsorganet ved den anden ende er indstilbart lejret til det andet ben mellem dettes midte og dets hængsling ved basiselementet, og at låseorganet med sin anden ende er hængslet til det andet ben mellem vægtud-What is new in the production is that the scissor stand is optionally placed under the seating / standing table platform, that the drive assembly comprises a weight equalizer and a locking member, both at one end of which are mounted to the base element, that the weight equalizer at the other end is adjustably mounted to the second leg between its center and its hinge at the base member, and the locking member with its other end being hinged to the second leg between

Den tekniske virkning 5Technical effect 5

Ved anbringelse af et enkelt saksestativ variabelt under sidde/ståbordets platform skabes der gode adgangsforhold, idet benene ikke er i vejen under arbejde ved bordet, og ved drivaggregatets udformning opnås en hurtig og enkel 10 højdejustering af sidde/ståbordet.By placing a single scissor stand variable under the seating / standing platform, good access conditions are created, as the legs are not in the way during work at the table, and in the design of the drive unit a quick and easy height adjustment of the sitting / standing table is achieved.

De uselvstændige krav omhandler fordelagtige udførelsesformer for sidde/ståbordet ifølge frembringelsen.The dependent claims relate to advantageous embodiments of the seating / standing table according to the invention.

Sidde/ståbordet ifølge frembringelsen forklares nærmere i enkeltheder i det følgende under henvisning til den vedlagte tegning, der viser sidde/ståbordet ifølge frembringelsen 20 set i sidebillede.The seating / standing table according to the invention is explained in more detail in the following with reference to the attached drawing which shows the sitting / standing table according to the creation 20 as seen in side view.

Udførelseseksempel På tegningen er med tallet 1 angivet en første udførelses-25 form for et sidde/ståbord ifølge frembringelsen. Bordet om fatter et basiselement 2, som har en støttedel 2a i tegningens plan. Basiselementet 2 har også en bæreflade 2b, der strækker sig et stykke til hver side af støttedelen 2a vinkelret på tegningens plan.Embodiment Example In the drawing, the number 1 indicates a first embodiment of a sitting / standing table according to the invention. The table includes a base member 2 having a support portion 2a in the plan of the drawing. The base member 2 also has a support surface 2b which extends one piece to each side of the support member 2a perpendicular to the plane of the drawing.

30 På basiselementet 2 er anbragt et saksestativ 3 med to ben 3a og 3b, der omkring deres midte er hængslet drejeligt om en aksel 3c. Benene 3a og 3b er i det væsentlige lige store og krydser hinanden ved akslen 3c. Hvert ben består af blot et lag eller profil med tilstrækkelig styrke til at modstå kræfter, som påvirker benene under sidde/ståbordets 1 be- 35 4 DK 96 00452 U3 lastning under brugen.30 On the base member 2 is mounted a scissor stand 3 with two legs 3a and 3b, which are hinged about a center 3 about a shaft 3c. The legs 3a and 3b are substantially equal and intersect at the shaft 3c. Each leg consists of just one layer or profile of sufficient strength to withstand forces that affect the legs during loading of the seating / standing table 1 during use.

Saksestativet 3 er forbundet til basiselementet 2, idet det første ben 3a har en aksel, i hvis ender to hjul 5 løber i hver sin U-skinne 6 parallelt med den øverste kant på det ene hjørne af støttedelen 2a. Ved det modsatte hjørne på støttedelen 2a og ligeledes ved den øverste kant er det andet ben 3b drejeligt fastgjort ved et hængsel 7.The scissor stand 3 is connected to the base member 2, the first leg 3a having a shaft, at the ends of which two wheels 5 run in their respective U-rail 6 parallel to the upper edge of one corner of the support part 2a. At the opposite corner of the support portion 2a and also at the upper edge, the second leg 3b is pivotally secured by a hinge 7.

I en foretrukken udførelsesform kan det andet ben 3b være suppleret med en afstivning i form af et ekstra ben 3d, der er lejret ved akslen 3c og ved sin anden ende har et med støttedelen 2a forbundet hængsel 7a, der svarer til det andet bens 3b hængsel 7. I denne udførelsesform ligger det andet ben 3b på tegningen foran det første ben 3a, og det ekstra ben 3d ligger bagved d€it første ben 3a, der således er indesluttet mellem det andet ben 3b og det ekstra ben 3d.In a preferred embodiment, the second leg 3b may be supplemented with a brace in the form of an additional leg 3d, which is mounted at the shaft 3c and at its other end has a hinge 7a connected to the support part 2a which corresponds to the hinge of the second leg 3b. 7. In this embodiment, the second leg 3b of the drawing is in front of the first leg 3a, and the extra leg 3d lies behind the first leg 3a, thus enclosed between the second leg 3b and the extra leg 3d.

Hvilende på saksestativet 3 findes en bordplade eller platform 8, der er fastgjort på tilsvarende måde, idet det første ben 3a i hovedsagen lodret oven over hængslet 7 er drejeligt forbundet til platformen 8 ved et hængsel 9, og det andet ben 3b ved sin ende ha.r en aksel, i hvis ender to hjul 10 løber parallelt i hver sin U-skinne 11 langs undersiden af platformen 8.Resting on the scissor stand 3 is a countertop or platform 8 which is similarly secured, the first leg 3a substantially vertically above the hinge 7 being pivotally connected to the platform 8 by a hinge 9, and the second leg 3b at its end having is an axle at the ends of which two wheels 10 run parallel to each other in U-rail 11 along the underside of the platform 8.

Platformen 8 kan derfor hæves eller sænkes i forhold til basiselementet 2 ved ændring af den indbyrdes vinkel mellem de to ben 3a og 3b, ved hvilken ændring hjulene 5 og 10 forskydes i de respektive U-skinner 6 henholdsvis 11, og benene drejer om hængslerne 7 henholdsvis 9.The platform 8 can therefore be raised or lowered relative to the base element 2 by changing the mutual angle between the two legs 3a and 3b, at which change the wheels 5 and 10 are displaced in the respective U-rails 6 and 11, respectively, and the legs rotate around the hinges 7 9 respectively.

Ved enderne af U-skinnerne 6 og 11 findes naturligvis stop, så hjulene ikke kan køre ud af U-skinnerne.Of course, at the ends of the U-rails 6 and 11 there are stops so that the wheels cannot run out of the U-rails.

5 DK 96 00452 U3 I basiselementet 2, for eksempel tæt ved bærefladen 2b, findes et leje 12, hvorpå et vægtudligningsorgan 13 er drejeligt understøttet ved sin ene ende. Vægtudligningsorganet 13 kan for eksempel være en gastrykcylinder af almindelig 5 kendt art. Vægtudligningsorganet 13 er ved sin anden ende indstilbart lejret i forhold til det andet ben 3b mellem dettes aksel 3c og dets hængsling 7 ved basiselementet 2.In the base element 2, for example close to the support surface 2b, there is a bearing 12 on which a weight equalizing means 13 is pivotally supported at one end. The weight equalizer 13 may, for example, be a gas pressure cylinder of a known type. The weight equalizer 13 is adjustable at its other end relative to the second leg 3b between its shaft 3c and its hinge 7 at the base member 2.

Til den indstilbare lejring i forhold til det andet ben 3b 10 findes en spindel 15, der omsluttes af en ikke vist møtrik, som ved et hængsel 14 er drejeligt forbundet med vægtudligningsorganet 13. Spindlen 15 kan roteres ved hjælp af en justernøgle, der er antydet med tallet 16 på tegningen, hvorved møtrikkens vandring på spindlen 15 kan frembringes. 15 Spindlen 15 ligger ved siden af det andet ben 3b og mellem dette og det ekstra ben 3d, når der findes et ekstra ben 3d.For the adjustable bearing relative to the second leg 3b 10, there is a spindle 15 which is enclosed by a nut not shown, which at a hinge 14 is pivotally connected to the weight equalizer 13. The spindle 15 can be rotated by means of an adjustable wrench indicated with the number 16 in the drawing, whereby the nut migration on the spindle 15 can be produced. The spindle 15 is adjacent to the second leg 3b and between this and the extra leg 3d when an extra leg 3d is found.

Ved en lille belastning af platformen 8 forskydes møtrikken 20 i retning mod hængslet 7, og ved stor belastning i retning mod akslen 3c.At a small load of the platform 8, the nut 20 is displaced in the direction towards the hinge 7, and at a large load in the direction towards the shaft 3c.

Der findes også et låseorgan 17, der ligeledes kan være en gastrykcylinder af almindelig kendt art. Låseorganet 17 25 tjener til låsning af benenes 3a, 3b indbyrdes vinkel og er ved sin ene ende svingbart lejret til basiselementet 2 ved et hængsel 18.There is also a locking means 17, which may also be a gas pressure cylinder of a generally known type. The locking member 17 25 serves to lock the legs 3a, 3b mutually at an angle and is pivotally mounted at one end to the base member 2 by a hinge 18.

Låseorganet 17 er med sin anden ende hængslet 19 til det 30 andet ben 3b mellem vægtudligningsorganets 13 indstilbare lejring 14, 15 og benets 3b hængsling 7 ved basiselementet 2.The locking means 17 is hinged at its other end 19 to the second leg 3b between the adjustable bearing 14, 15 of the weight equalizer 13 and the hinging 7 of the leg 3b at the base element 2.

Ved sidde/ståbordet 1 ifølge frembringelsen består drivaggregatet således af to dele: Et vægtudligningsorgan 13 og et låseorgan 17, hvor vægtudligningsorganet 13 først betje- 35 6 DK 96 00452 U3 nes til nulstilling af vægten på platformen 8. Dernæst låses saksestativet 3 i den ønskede højde ved hjælp af låseorganet 17.Thus, at the seating / standing table 1 according to the invention, the drive assembly consists of two parts: a weight equalizer 13 and a locking means 17, where the weight equalizer 13 is first operated to reset the weight of the platform 8. Next, the scissor frame 3 is locked in the desired height by means of the locking means 17.

5 Hvis der ikke er behov for en udligning af belastnincjen på platformen 8, kan sidde/ståbordet i en modificeret udførelsesform være uden vægtudligningsorgan 13 og et låseorgan 17, idet disse to organer i stedet for erstattes af en enkelt spindel 20, som er anbragt under platformen 8 og er 10 lejret roterbart, men uforskydeligt i sin længderetning ved hængslet 9. Spindlen 20 omsluttes af en møtrik, der er fastgjort ved hjulene 10 på den anden arm 3b. Ved rotation af spindlen 20 bevæges møtrikken hen langs spindlen sammen med hjulene 10, så benenes 3a, 3b indbyrdes vinkel ændres til hævning/sænkning af platformen 8.In the absence of an equalization of the load on the platform 8, the seating / standing table in a modified embodiment may be without weight equalizer 13 and a locking means 17, instead of replacing these two means by a single spindle 20 which is placed underneath. the platform 8 and 10 are rotatably mounted, but slidably longitudinally at the hinge 9. The spindle 20 is enclosed by a nut attached to the wheels 10 of the second arm 3b. When rotating the spindle 20, the nut is moved along the spindle along with the wheels 10, so that the angles of the legs 3a, 3b are mutually angled to raise / lower the platform 8.
