TRANSPORTVOGNTRANSPORT TROLLEY

Opfindelsen angår en transportvogn omfattende en nedre bærende ramme med kørehjul og en med den bærende ramme til-5 nærmelsesvis parallelt forløbende bærende plade, hvilken bærende plade ved hjælp af forskydningsorganer, der i den ene ende ligger an mod den bærende ramme og/eller forbindelseselementer til den bærende ramme og med dele af den anden ende ligger an mod den bærende plades nedre flade el-10 ler forbindelseselementer til den bærende plade forskydes vertikalt i forhold til den bærende ramme.The invention relates to a transport trolley comprising a lower supporting frame with driving wheels and a supporting plate extending approximately parallel to the supporting frame, which supporting plate by means of displacing means abutting at one end against the supporting frame and / or connecting elements for the supporting frame and with parts of the other end abut against the lower surface of the supporting plate or connecting elements to the supporting plate are displaced vertically relative to the supporting frame.

Kendte transportvogne, der anvendes til transport af større og tunge enheder, eksempelvis hårde hvidevarer og kopi-15 maskiner, omfatter blandt andet deciderede sækkevogne eller rulleborde.Known transport trolleys used for transporting large and heavy units, for example white goods and copiers, include, among other things, fixed sack trolleys or trolleys.

Sækkevognene virker ved, at vognen, der i vertikal stilling skubbes ind under lasten, vippes, hvorved tyngdepunktet 20 forskubbes til et punkt, som gør det muligt at transportere lasten uden større besvær. Sækkevognen letter således arbejdet med selve transporten fra et punkt til et andet, men afhjælper ikke det fysiske problem, der er ved at hæve og sænke lasten fra et niveau til et andet, hvilket dels inde-25 bærer risiko for rygskader, dels ved større opgaver kræver flere personer.The sack carriages operate by tilting the carriage, which is pushed under the load in the vertical position, whereby the center of gravity 20 is displaced to a point which makes it possible to transport the cargo without great difficulty. The sack trolley thus facilitates the work of the actual transport from one point to another, but does not alleviate the physical problem of raising and lowering the load from one level to another, which partly entails a risk of back injuries and partly major tasks. requires more people.

Fra DE/A/3614877 kendes en transportvogn for transport af især vasketøj, som er sammenklappelig. Vognen er uanvende-30 lig til transport af tungt gods og kan ikke rejses op til vertikal stilling og således gøre det muligt at transportere gods, sådan som det kendes eksempelvis fra sækkevogne.DE / A / 3614877 discloses a transport trolley for transporting especially laundry, which is collapsible. The trolley is unusable for transporting heavy goods and cannot be raised to a vertical position and thus makes it possible to transport goods, as is known, for example, from sack wagons.

Rullebordene har i forhold til sækkevognene den fordel, at 35 højden herpå kan vælges ud fra det højdeniveau, lasten skal afhændes fra eller placeres på, og letter således løfte- DK 172090 B1 2 eller sænkearbejdet. Vognen tilgodeser dog ikke det fulde transportbehov, idet den ikke kan indstilles som funktion af arbejdshøjden og ej heller kan hæve/sænke den transporterede last.In relation to the sack carts, the trolleys have the advantage that the height thereof can be selected on the basis of the height level at which the load is to be disposed of or placed, and thus facilitates the lifting or lowering work. However, the trolley does not meet the full transport requirement, as it cannot be adjusted as a function of the working height, nor can it raise / lower the transported load.

Det er formålet med opfindelsen at tilvejebringe en transportvogn, der ikke har den kendte tekniks ulemper, og hvor det let og ubesværet er muligt at få emner placeret i ét højdeniveau transporteret til et modtagelsessted eventuelt 10 i et andet niveau, uden at det er nødvendigt manuelt at hæve/sænke lasten, idet dens hæve/sænke funk ti on er en integreret del af transportvognen og hvor transportvognen kan anvendes som en decideret sækkevogn. Dette har stor betydning ved tung og svær transportabel last, idet en sækkevogn 15 i forhold til andre transportvogne er nemmere at dirigere rundt med og eksempelvis forcere ujævne underlag med. Herved reduceres risikoen for rygskader samtidig med, at bemandingen for transport af tunge genstande minimeres.It is the object of the invention to provide a transport trolley which does not have the disadvantages of the prior art, and where it is easily and effortlessly possible to have items placed in one height level transported to a reception point or possibly in another level, without the need for manual to raise / lower the load, as its raising / lowering function is an integral part of the transport trolley and where the transport trolley can be used as a definite sack trolley. This is of great importance in the case of heavy and heavy transportable loads, as a sack trolley 15 in relation to other transport trolleys is easier to direct around with and, for example, climb uneven surfaces with. This reduces the risk of back injuries while minimizing manning for the transport of heavy objects.

20 Desforuden er transportvognen også anvendelig til at transportere effekter liggende på gulvniveau, idet lasten vipper over på transportvognen, der i dette tilfælde er klappet sammen og håndteres i vertikal stilling, og således fungerer som sækkevogn.20 In addition, the transport trolley is also usable for transporting effects lying at floor level, the load tilting onto the transport trolley, which in this case is folded and handled in a vertical position, and thus functions as a sack trolley.

Dette formål opnås ved at udforme transportvognen ifølge opfindelsen, så at den bærende ramme tillige omfatter en i forhold til den bærende ramme tilnærmelsesvis vinkelret forløbende bundplade fæstnet til den ene ende af den bæren-30 de ramme samt håndtag fæstnet til den modsat liggende ende af den bærende ramme.This object is achieved by designing the transport trolley according to the invention so that the supporting frame also comprises a base plate extending approximately perpendicularly to the supporting frame attached to one end of the supporting frame and handles attached to the opposite end of the load-bearing frame.

Ved at h^ve en bæreplade, der er vertikal forskydeligt anbragt i forhold til bærerammen, er det muligt at placere 35 pladen ud for emnet, der ønskes flyttet, og skubbe dette over på bærepladen. Herefter sænkes lasten eventuelt såle- DK 172090 B1 3 des, at tyngdepunktet ligger hensigtsmæssigt lavt. Transportvognen vippes nu op til tilnærmelsesvis lodret stilling, idet der gribes fat i de dertil indrettede håndtag.By having a support plate which is vertically displaceably arranged relative to the support frame, it is possible to place the plate next to the workpiece which it is desired to move and push it onto the support plate. The load may then be lowered so that the center of gravity is suitably low. The transport trolley is now tilted up to an approximately vertical position, gripping the handles arranged for this purpose.

Den vertikale plade fungerer nu som bundplade og lasten kø-5 res nu hen til modtagelsesstedet, hvor vognen sættes ned i vandret stilling. Pladen reguleres igen via forskydningsorganer til den højde, der modsvarer modtagelsesstedets højde, og lasten skubbes nu på plads.The vertical plate now acts as a base plate and the load is now driven to the receiving point, where the carriage is lowered into a horizontal position. The plate is again adjusted via displacement means to the height corresponding to the height of the receiving point, and the load is now pushed into place.

10 Ved at udforme transportvognen ifølge opfindelsen som angivet i krav 2 og 3 opnås en hensigtsmæssig udformning af forskydningsorganet, således at det dels ved sammenfoldning fylder minimalt, dels ved maksimal højde af vognen giver stabilt anlæg for den bærende plade.By designing the transport trolley according to the invention as stated in claims 2 and 3, a suitable design of the displacing member is obtained, so that it fills minimally at folding, partly at maximum height of the trolley, provides stable abutment for the supporting plate.

Ved at udforme transportvognen ifølge opfindelsen som angivet i krav 4 opnås en enkel og solid udformning af organet til aktivering af hæve/sænkefunkt ionen, og som via sit kraftoverførselsprincip sikrer, at der kun skal bruges små 20 kræfter for at aktivere forskydningsorganet og hæve/sænke lasten.By designing the transport trolley according to the invention as stated in claim 4, a simple and solid design of the means for activating the raising / lowering function is obtained, and which via its power transmission principle ensures that only small forces are needed to activate the displacing means and raising / lowering the load.

Ved at udforme transportvognen ifølge opfindelsen som angivet i krav 5 og 6 opnås, at pladen kan hæves og sænkes med 25 minimal friktion mellem ramme, forskydningsorgan og plade.By designing the transport trolley according to the invention as stated in claims 5 and 6, it is achieved that the plate can be raised and lowered with minimal friction between frame, displacement means and plate.

Ved at udforme transportvognen ifølge opfindelsen som angivet i krav 7 opnås, at pladens udformning kan vælges og fremstilles ud fra lastens geometri og vægt.By designing the transport trolley according to the invention as stated in claim 7, it is achieved that the design of the plate can be selected and manufactured on the basis of the geometry and weight of the load.

Opfindelsen forklares herefter nærmere i forbindelse med en foretrukken udførelsesform under henvisning til tegningen, hvor 35 fig. 1 viser transportvognen set i et midtersnit og fra siden, DK 172090 B1 4 fig. 2 viser transportvognen set fra den ene ende, fig. 3a viser et fastgørelsesprincip for den bærende pla-5 de, fig. 3b viser forskydningsorganets udløselige indgrebsdel.The invention will now be explained in more detail in connection with a preferred embodiment with reference to the drawing, in which fig. 1 shows the transport trolley seen in a central section and from the side, DK 172090 B1 4 fig. 2 shows the transport trolley seen from one end, fig. 3a shows a fastening principle for the supporting plate 5, fig. 3b shows the releasable engaging part of the displacing member.

10 På fig. 1 og 2 ses transportvognen, som er opbygget af en transportenhed 1, et forskydningsorgan 2, et spindelorgan 7, 19 samt en aftagelig plade 3.In FIG. 1 and 2 show the transport trolley, which is built up of a transport unit 1, a displacing member 2, a spindle member 7, 19 and a removable plate 3.

Transportenheden 1 er udformet af en rektangulær bærende 15 ramme 11, eksempelvis fremstillet i metalprofiler, hvis langsgående profiler er udformet med skinner, hvori forskydningsorganets hjul 21 kan glide. På den bærende ramme 11 er hæftet fire hjul 5 og 4, hvoraf de to bageste 5 er mindre i diameter end de forreste hjul 4, (der eksempelvis 20 er forbundet med hinanden via en aksel 24) og i øvrigt er roterbare omkring en vertikal akse, hvorfor styring af disse hjul er mulig, samt har tilkoblet en bremsemekanisme 25, der virker efter kendte principper.The transport unit 1 is formed by a rectangular supporting frame 11, for example made of metal profiles, the longitudinal profiles of which are formed with rails in which the wheels 21 of the displacing member can slide. Attached to the supporting frame 11 are four wheels 5 and 4, of which the two rear 5 are smaller in diameter than the front wheels 4, (which for example 20 are connected to each other via a shaft 24) and are otherwise rotatable about a vertical axis. , why steering of these wheels is possible, as well as having coupled a braking mechanism 25 which operates according to known principles.

25 Hjulophænget kan også være et trepunktsophæng, hvorved det er nemmere at forcere trapper.25 The wheel suspension can also be a three-point suspension, making it easier to climb stairs.

I samme ende som de små hjul 5 er der tildannet to håndtag 13, udformet eksempelvis af faconbukkede rør og eventuelt 30 aftagelige. Modsat disse håndtag 13 i den anden ende er der fæstnet en i forhold til den bærende ramme tilnærmelsesvis vinkelret forløbende bundplade 12.At the same end as the small wheels 5, two handles 13 are formed, formed for example of shaped bent pipes and possibly 30 removable. Opposite these handles 13 at the other end, a base plate 12 extending approximately perpendicularly to the supporting frame is attached.

Forskydningsorganet 2 består af to over for hinanden lig-35 gende saksebenpar 6, der med tværstivere 14 er forbundet til hinanden. Hvert saksebenpar består af to ben 16 og 17, DK 172090 B1 5 hvoraf det ene ben 17 har fæstnet et hjul 21 i den ene ende 17a, så det kan glide i rammens skinne, hvorpå det ligger an, og i den anden ende 17b er fæstnet roterbart 22 til spindelorganet eller forbindelseselementer dertil. Det an-5 det bens 16 ene ende 16a, og som vender mod rammen 11, er fæstnet udløseligt til dette via en krogagtig udformning 20, som det fremgår af fig. 3b. I den anden ende 16b er benet udstyret med et hjul 18, der glider langs den bærende plades 3 nederste flade. Den anden ende er også fæstnet ro-10 terbart til spindelorganets gevindbøsning 19 ved hjælp af forbindelseselementerne 23 og følger således dettes horisontale bevægelser, hvorfor benets ene ende 16a tvinges i modsat retning og via akslen 15 tvinger det andet ben 17 til at udføre den modsat rettede bevægelse. Herved udføres 15 saksebevægelsen.The displacement means 2 consists of two pairs of scissor legs 6 facing each other, which are connected to each other by cross braces 14. Each pair of scissor legs consists of two legs 16 and 17, DK 172090 B1 5 of which one leg 17 has attached a wheel 21 at one end 17a so that it can slide in the rail of the frame on which it rests and at the other end 17b is attached rotatably 22 to the spindle member or connecting members thereto. The one end 16a of the other leg 16, which faces the frame 11, is releasably attached thereto via a hook-like configuration 20, as shown in FIG. 3b. At the other end 16b, the leg is provided with a wheel 18 which slides along the lower surface of the supporting plate 3. The other end is also rotatably attached to the threaded sleeve 19 of the spindle member by means of the connecting elements 23 and thus follows its horizontal movements, so that one end 16a of the leg is forced in the opposite direction and via the shaft 15 the other leg 17 forces to perform the opposite direction. movement. Hereby the scissor movement is performed.

Rotation af spindelen 7 frembringes enten ved at dreje på et håndtag 8 eller ved at udforme gevindspindelens ende 9 med et indvendigt sekskantet tværsnit således, at eksempel-20 vis en motor, såsom en boremaskine kan benyttes til at hæve og sænke bærepladen.Rotation of the spindle 7 is produced either by turning a handle 8 or by forming the end 9 of the threaded spindle with an internal hexagonal cross-section so that, for example, a motor such as a drilling machine can be used to raise and lower the support plate.

Spindelorganet omfatter en langsgående gevindspindel 7, der i den ene ende omsluttes af gevindbøsningen 19 samt for-25 bindelseselementer 23 til forskydningsorganet. Gevindbøs ningen er hæftet roterbart til forbindelseselementerne 23.The spindle means comprises a longitudinal threaded spindle 7, which is enclosed at one end by the threaded sleeve 19 as well as connecting elements 23 for the displacement means. The threaded sleeve is rotatably attached to the connecting elements 23.

Den aftagelige og udskiftelige bæreplade 3 er fæstnet til spindelorganets/forskydningsorganet via splits 10, som det ses af fig. 3a, eller ved hjælp af fingerskruer.The removable and replaceable support plate 3 is attached to the spindle member / displacement member via splice 10, as seen in fig. 3a, or by means of thumbscrews.
