Den foreliggende opfindelse angår en løftevogn af den i den indledende del af krav 1 angivne type og især indrettet til indendørs brug, eksempelvis til løftning af paketterede varer fra lastpaller.The present invention relates to a lifting trolley of the type specified in the preamble of claim 1 and in particular arranged for indoor use, for example for lifting packaged goods from pallets.

05 Sådanne løftevogne er kendt i flere former. Det er dog sæd vanligt, at disse kendte vogne, for at løfte et løftebord langs en i hovedsagen lodret søjle, har til løftebordet fastgjorte kæder eller liner, som løber over en venderulle eller tilsvarende ved søjlens Øverste del. Da kæderne skal være belagt med smøremiddel, forhin-10 drer denne konstruktion, at løftevognen kan vaskes fuldstændigt og eventuelt desinficeres, hvilket er nødvendigt ved visse anvendelser, eksempelvis på hospitaler og apoteker.05 Such lifting trolleys are known in several forms. It is common practice, however, that these known carriages, in order to lift a lifting table along a substantially vertical column, have chains or lines attached to the lifting table, which run over a turning roller or equivalent at the upper part of the column. Since the chains must be coated with lubricant, this construction prevents the trolley from being completely washed and possibly disinfected, which is necessary for certain applications, for example in hospitals and pharmacies.

Fransk patentskrift nr. 1.376.014 viser et eksempel på en løftevogn af den aktuelle type, hvori søjlen er sammensat af indbyrdes 15 forbundne U-profiler, og hvor løftebordet bliver bevæget langs søjlen ved hjælp af et remsystem, der er kompliceret og enten er helt åbent eller kræver omfattende afskærmninger.French Patent Specification No. 1,376,014 shows an example of a lifting trolley of the current type, in which the column is composed of interconnected U-profiles, and in which the lifting table is moved along the column by means of a belt system which is complicated and either complete. open or requires extensive fencing.

Ovenstående ulempe afhjælpes ved hjælp af den foreliggende opfindelse, der tilvejebringer en i sin helhed vaskbar løftevogn, 20 som desuden er enkel og billig at fremstille.The above disadvantage is remedied by the present invention, which provides a fully washable lifting trolley, which is moreover simple and inexpensive to manufacture.

Løftevognen ifølge opfindelsen er ejendommelig ved det i den kendetegnende del af krav 1 angivne. Dermed opnås en løftevogn, som er særlig velegnet til anvendelse, hvor der tilstræbes høj renlighed, idet tandremmen ikke kræver smøring og for en stor dels 25 vedkommende kan løbe i den dannede firkantkanal.The lifting trolley according to the invention is characterized by what is stated in the characterizing part of claim 1. This results in a lifting trolley which is particularly suitable for use where high cleanliness is sought, as the toothed belt does not require lubrication and can for the most part run in the formed square channel.

I krav 2 angives en hensigtsmæssig håndsvingsbetjent udførelsesform for løftevognen ifølge opfindelsen.Claim 2 states a suitable crank-operated embodiment of the lifting trolley according to the invention.

I det følgende skal opfindelsen beskrives nærmere under henvisning til tegningen, hvor 30 figur 1 er et perspektivisk billede af en løftevogn ifølge opfin delsen, figur 2 løftevognen i figur 1 set fra siden, figur 3 en skematisk afbildning af den øverste og den nederste ende af en i løftevognen indgående søjle samt det indre af et hånd-35 svingshus, figur 4 en del af søjlen ved stedet for håndsvingshusets tilslutning til søjlen, 145642 2 figur 5 et sidebillede af en modificeret udførelsesform for løftevognen, og figur 6 et snit langs linien A-A og linien B-B i figur 2.In the following, the invention will be described in more detail with reference to the drawing, in which Figure 1 is a perspective view of a lifting trolley according to the invention, Figure 2 the lifting trolley in Figure 1 seen from the side, Figure 3 a schematic view of the upper and lower end of a column included in the carriage and the interior of a crankcase, Figure 4 a part of the column at the site of the crankcase connection to the column, Figure 5 a side view of a modified embodiment of the carriage, and Figure 6 a section along the line AA and the line BB in Figure 2.

I figurerne 1 og 2 vises en løftevogn ifølge opfindelsen, som 05 indeholder en vandret liggende ramme 2 bestående af firkantbjælker og i hovedsagen formet som et H. Ved de yderste ender er rammen 1 forsynet med kørehjul 2 til flytning af vognen. Pi rammen er der fastgjort en opretstående søjle 3, der fortrinsvis står vinkelret på planet for rammen 1. En løftegaffel 4 eller et løftebord er anbragt -JO forskydeligt langs i hovedsagen hele søjlens 3 højde. Endvidere findes en mekanisme, som generelt er betegnet med henvisningstallet 5, til drivning af iøftegaflen 4 langs søjlen.Figures 1 and 2 show a lifting trolley according to the invention, which 05 contains a horizontal frame 2 consisting of square beams and substantially shaped as an H. At the outer ends the frame 1 is provided with drive wheels 2 for moving the trolley. Attached to the frame is an upright column 3, which is preferably perpendicular to the plane of the frame 1. A lifting fork 4 or a lifting table is arranged -JO displaceably along substantially the entire height of the column 3. Furthermore, there is a mechanism, generally denoted by the reference numeral 5, for driving the lifting fork 4 along the column.

Søjlen 3 indeholder i tværsnit to U-profiler 6, 7, som er vendt med de åbne partier rettet bort fra hinanden, se figur 3 og 4. To 15 plader 8, 9 er fastgjort, fortrinsvis svejst, til U-profilernes frie ben, således at der dannes en i tværsnit firkantet kanal 10 af ll-profilernes bundpartier 11, 12 samt nævnte plader 8, 9.The column 3 contains in cross section two U-profiles 6, 7, which are turned with the open portions facing away from each other, see Figures 3 and 4. Two 15 plates 8, 9 are attached, preferably welded, to the free legs of the U-profiles, so as to form a cross-sectional square channel 10 of the bottom portions 11, 12 of the II profiles as well as said plates 8, 9.

Løftegaflen 4 har et bæreorgan 13, se figur 6, hvori der er lejret ruller 14, 15 i hver af to niveauer, som modsvarer snittene 20 A-A og B-B i figur 2. Hver af rullerne 14, 15 er lejret ved hjælp af respektive akseltappe 16, 17. Rullerne løber imod de to U-profil-ers inderste vægge, der står vinkelret på løftegaflens 4 ben 18. I og med at løftegaflen 4 belaster rullerne 15, 16 også uden last på gaflen, vil rullerne løbe mod de nærmest løftegaflen 4 beliggende af 25 nævnte vægge.The lifting fork 4 has a support member 13, see figure 6, in which rollers 14, 15 are mounted in each of two levels, which correspond to the sections 20 AA and BB in figure 2. Each of the rollers 14, 15 is mounted by means of respective shaft pins 16 , 17. The rollers run against the inner walls of the two U-profiles, which are perpendicular to the legs 18 of the lifting fork 4. Since the lifting fork 4 loads the rollers 15, 16 also without load on the fork, the rollers will run towards the nearest lifting fork 4. located by 25 said walls.

Drivmekanismen 5 indeholder en tandrem 19, hvis to ender er fastgjort til bæreorganet 13. Tandremmen 19 løber fra bæreorganet 13 og i en ubrudt sløjfe 20 langs hele søjlen 3 på den side 21, hvor løftegaflen 4 er anbragt, og videre, fortrinsvis inden i nævnte fir-30 kantkanal 10 (se figur 3), tilbage til bæreorganet 13. Tandremmens 19 sløjfe 20 fremgår særligt tydeligt af figur 2.The drive mechanism 5 comprises a toothed belt 19, two ends of which are attached to the support member 13. The toothed belt 19 runs from the support member 13 and in an unbroken loop 20 along the entire column 3 on the side 21 where the lifting fork 4 is arranged, and further, preferably within said fir-30 edge channel 10 (see figure 3), back to the support member 13. The loop 20 of the toothed belt 19 is particularly clear from figure 2.

Drivmekanismen 5 indeholder endvidere en kraftoverførende del, som i en udførelsesform udgøres af et manuelt håndsving 22 med tilhørende drev, der er lejret i et hus 23, som er fastgjort til 35 søjlen 3 på dennes bort fra løftegaflen 4 vendende side 24. Tandremmen 19 forløber ud fra nævnte firkantkanal 10 igennem en åbning 25, se figur 4, derfra over et drev 26, som er i indgreb med 145642 3 et andet drev 27 koblet til håndsvinget 22, og videre ind i firkantkanalen 10 igennem åbningen 25.The drive mechanism 5 further comprises a force-transmitting part, which in one embodiment is constituted by a manual crank 22 with associated drive, which is mounted in a housing 23, which is attached to the column 3 on its side 24 facing away from the lifting fork 4. The toothed belt 19 extends from said square channel 10 through an opening 25, see figure 4, thence over a drive 26 which engages a second drive 27 coupled to the crank 22, and further into the square channel 10 through the opening 25.

Ved åbningen 25 er der anbragt to venderuller 28, 29 for tandremmen 19. Endvidere findes en venderulle 30 i søjlens 3 øver-05 ste ende samt en venderulle 31 i søjlens nederste ende.At the opening 25, two reversing rollers 28, 29 are arranged for the toothed belt 19. Furthermore, there is a reversing roller 30 at the upper end of the column 3 and a reversing roller 31 at the lower end of the column.

Drevene 26, 27 samt venderullerne 28, 29, 30, 31 er vist mere detaljeret i figur 3.The drives 26, 27 and the turning rollers 28, 29, 30, 31 are shown in more detail in Figure 3.

Imellem håndsvingets 22 aksel og drevets 27 aksel findes en friktionskobiing 32, for at tandremmen 19 ikke skal kunne overbela-10 stes. Friktionskoblingen 32 indeholder hensigtsmæssigt et frihjul, der er indrettet således, at de udkobler friktionskoblingen, når en last hejses op, og indkobler friktionskoblingen, når en last hejses ned.Between the shaft of the crank 22 and the shaft of the drive 27 there is a friction coupling 32, so that the toothed belt 19 can not be overloaded. The friction clutch 32 suitably includes a freewheel arranged so as to disengage the friction clutch when a load is hoisted up and engage the friction clutch when a load is hoisted down.

Fra rammen 1 udgår en bøjle 33, der også er fastgjort til den 15 øverste del af søjlen 3 ved hjælp af en stiver 34. Denne bøjle anvendes til at flytte løftevognen.From the frame 1 a bracket 33 emerges, which is also fastened to the upper part of the column 3 by means of a strut 34. This bracket is used to move the lifting carriage.

Tandremmen er af en type, som kan modstå høje temperaturer over 100°C, og som ikke kræver smøring. Fortrinsvis anvendes stålarmeret plast.The toothed belt is of a type which can withstand high temperatures above 100 ° C and which does not require lubrication. Steel-reinforced plastic is preferably used.

20 Løftevognen er i øvrigt udført af rustfrit stål og/eller alumini um, og kørehjulene 2 er udført i et materiale, som kan modstå høje temperaturer over 100°C.The lifting trolley is otherwise made of stainless steel and / or aluminum, and the drive wheels 2 are made of a material that can withstand high temperatures above 100 ° C.

Hele løftevognen kan således vaskes i vaskemaskiner beregnet til sådanne store indretninger, uden at dele af vognen ødelægges 25 eller undergår forandringer. Anvendelse af en tandrem medfører, at smøring ikke er nødvendig, således som det er tilfældet, når der anvendes kæder eller liner til at bevæge løftegaflen 4. Tandremmens 19 afsnit inden i søjlen 3 og uden på søjlen 3 på den side 21, hvorpå løftegaflen 4 er anbragt, medfører, at tandremmen 19 er tilstræk-30 keligt beskyttet og samtidigt er let at inspicere.The entire lifting trolley can thus be washed in washing machines intended for such large devices, without parts of the trolley being destroyed or undergoing changes. The use of a timing belt means that lubrication is not necessary, as is the case when chains or lines are used to move the lifting fork 4. The sections of the timing belt 19 inside the column 3 and outside the column 3 on the side 21 on which the lifting fork 4 is arranged, means that the toothed belt 19 is sufficiently protected and at the same time is easy to inspect.

Ifølge en anden udførelsesform indeholder drivmekanismen 5 en elektrisk motor 35 i stedet for håndsvinget 22, se figur 5. Motoren kan være af en helt tæt type, nemlig en såkaldt neddykkelig type, hvorved hele løftevognen kan vaskes ved høje temperaturer og kan 35 desinficeres ved høje temperaturer og højt tryk.According to another embodiment, the drive mechanism 5 comprises an electric motor 35 instead of the crank 22, see figure 5. The motor can be of a completely tight type, namely a so-called submersible type, whereby the whole lift car can be washed at high temperatures and can be disinfected at high temperatures and high pressure.

Motoren kan være batteridrevet, idet batterierne hensigtsmæssigt placeres på en ikke vist hylde, der er sluttet ti! den bagesteThe motor can be battery-powered, the batteries being conveniently placed on a shelf (not shown) connected ten! the rear
