Abstract

The invention is based on the problem how to provide a concept of an utmost lightweight and handy handcart which could be produced simply and cheaply, and would be unconditionally reliable and safe without lifting and lowering, provide the possibility of clamping and subsequently manual transportation as well as unfastening of gas cylinders for households, and apart from that similar containers or similar objects serving other purposes, where a similar attachment to the handcart is possible. At the same time the handcart when loaded should be suitable for safe transportation in vehicles with an available flat surface, particularly at the bottom of a car trunk. The handcart includes a U-shaped framework from pipes (10), consisting of two parallel legs (11, 12) as well as a handle (13) between them. On the outermost ends of these legs (11, 12) there is an axis (19) featuring wheels (5', 5''). In the central part (14) of the framework (10) there is a slip piece (20) featuring a bolt (27) and movable along the legs (11, 12) against the force of a spring (24). On each of the legs (11, 12) there is on their outermost terminal part at least one support (1, 2) available.

Description

Ročni vozičekHand trolley

Izum se nanaša na ročni voziček, zlasti za prevoz posod. Kot posoda v tem primeru pride v poštev bodisi plinska jeklenka, zlasti takšna za uporabo v gospodinjstvu, ali tudi druga posoda, npr. nakupovalno košaro ali podobna posoda, ki je vsaj na zgornjem in spodnjem robu zasnovana s po vsaj enim vsaj približno kot izsek obroča zasnovanim in razmeroma togim območjem, prirejenim vsakokratnim zahtevam v zvezi s pritrditvijo vsakokratne posode na voziček.The invention relates to a hand trolley, in particular for the transport of containers. In this case, either a gas cylinder, especially one for domestic use, or another container, e.g. a shopping basket or similar container designed at least at the upper and lower edges with at least one at least approximately a portion of the ring designed and relatively rigid, adapted to the particular requirements for attaching the respective container to the trolley.

Izum temelji na problemu, kako zasnovati karseda, lahek, priročen ter na enostaven in cenen način izvedljiv ročni voziček, ki naj bi na brezpogojno zanesljiv in varen način brez dviganja in spuščanja omogočal vpenjanje in zatem ročno prevažanje ter nato tudi odpenjanje oz. raztovarjanje plinskih jeklenk za gospodinjstvo in razen tega tudi podobnih posod oz. podobnih predmetov za druge namene, pri katerih je možna analogna pritrditev na voziček, hkrati pa naj bi bil voziček v natovorjenem stanju prirejen tudi za varno prevažanje na vozilu z razpoložljivo ravno podlago, zlasti npr.na dnu prtljažnega prostora osebnega avtomobila.The invention is based on the problem of how to design as simple, easy, convenient and in a simple and inexpensive way feasible hand trolley, which should in unconditionally reliable and secure way without lifting and lowering enable clamping and then manually transporting and then unlocking or. unloading of gas cylinders for the household and, in addition, similar containers or containers. similar articles for other purposes, for which an analogue attachment to the trolley is possible, and at the same time the trolley in the loaded state is also designed to be safely carried on a vehicle with a flat surface available, in particular, for example, at the bottom of the luggage compartment of a passenger car.

Iz patentne literature so znane Številne rešitve ročnih priprav za prevažanje tovora. Tako je npr. znana samokolnica, ki je sicer prednostno namenjena za prevoz sipkega ali gosto tekočega gradbenega materiala in s pomočjo katere je v splošnem možno na določeno razdaljo prepeljati tudi plinsko bombo za gospodinjske potrebe. Dve rešitvi samokolnice sta opisani v EP 0 218 520 in WO 90/03 907. Pri prevažanju npr. plinske jeklenke s samokolnico ali njej podobnim vozičkom se uporabnik sooča s problematičnim nakladanjem in razkladanjem razmeroma težke jeklenke, ki jo je potrebno dvigniti na precejšnjo višino in seveda tudi spustiti s precejšnje višine. Po drugi strani pa na samokolnici naložena jeklenka ni vpeta, zato se lahko kotali sem ter tja ter s tem ogroža stabilnost samokolnice med prevažanjem in so za obdržanje stabilnosti pač potrebni toliko večji napori uporabnika. Še nadalje je težišče na samokolnici naloženega bremena razmeroma visoko nad podlago, kar spet ogroža stabilnost tovora in terja izdatne napore uporabnika za realizacijo varnega prevažanja tovora. Taisti problem se kaže tudi v primeru, če bi na samokolnici naloženo jeklenko prevažali na ravni podlagi v prtljažnem prostoru osebnega avtomobila, pri čemer je zaradi visokega težišča brez dodatnega zavarovanja s pomočjo vezi ali drugih pritrdilnih sredstev nemogoče izključiti možnost prevračanja, razen tega pa je tudi skupna višina na samokolnici naloženega tovora lahko problematična z vidika samega razpoložljivega prostora.The patent literature discloses a number of solutions for manual cargo handling. Thus, e.g. a well-known wheelbarrow, which is preferably used for the transport of bulk or dense liquid building materials, which generally makes it possible to carry a gas bomb for household purposes over a certain distance. Two wheelbarrow solutions are described in EP 0 218 520 and WO 90/03 907. When carrying e.g. gas cylinders with wheelbarrow or similar trolley, the user is faced with the problematic loading and unloading of a relatively heavy cylinder, which must be raised to a considerable height and, of course, also lowered from a considerable height. On the other hand, the cylinder loaded on the wheelbarrow is not clamped, so it can roll here and there, thus endangering the stability of the wheelbarrow during transport, and the greater effort of the user is required to maintain stability. Furthermore, the center of gravity on the wheelbarrow of the loaded load is relatively high above the ground, which again threatens the stability of the cargo and requires considerable effort on the part of the user to realize the safe transport of cargo. This problem is also manifested in the fact that the cylinder loaded on a wheelbarrow would be transported on a flat basis in the luggage compartment of a car, and because of the high center of gravity it is impossible to exclude the possibility of rollover without additional securing by means of ties or other fastening means. the total height on the wheelbarrow of the loaded cargo can be problematic in terms of the space available.

Nadalje je splošno znan tkzv. skladiščni ročni transportni voziček, ki sestoji iz ogrodja, ki je v pogledu od strani izvedeno v obliki črke L. Daljši krak ogrodja, ki je v delovnem položaju vozička vsaj približno pravokoten ali postavljen nekoliko poševno glede na podlago, je zgoraj podaljšan v ustrezni držali, s pomočjo katerih je možno upravljati voziček. Krajši krak ogrodja je izveden kot podloga za vsakokraten tovor in se med uporabo nahaja vsaj približno vzporedno s podlago oz. nekoliko poševno glede na podlago. Naposredno ob krajšem kraku oz. za njim se nahaja par koles, ki sta prosto vrtljivi in nameščeni vsako na svoji strani vozička. Kolesi sta med seboj soosni. Med nalaganjem bremena se podloga vsaj s svojim prednjim robom praviloma nahaja na podlagi, tako da breme lahko potisnejo nanjo. Zatem, voziček nagnejo, tako da se tovor oz. breme nasloni na daljši krak ogrodja. Dominantno komponento teže bremena naj bi prevzeli kolesi in uporabnik naj bi se torej soočal zgolj z manjšim deležem siceršnje obremenitve. Breme je sicer v splošnem možno tudi pritrditi na ogrodje, vendar večina univerzalnih vozičkov s pritrdilnimi sredstvi niti ni opremljena. Taki vozički so masivni, robustni in razmeroma težki ter večidel primerni predvsem za uporabo v industriji in skladiščih in razen tega praviloma tudi zgolj s strani oseb, ki so primemo poučene vFurthermore, the so-called so-called so-called. a hand-held storage trolley consisting of a skeleton, in side view, made in the shape of an L. The longer arm of the skeleton, which is at least approximately orthogonal to the working position of the trolley, is lengthened above in a suitable holder, with which the trolley can be operated. The shorter arm of the frame is designed as a support for each load and, during use, is at least approximately parallel to the base or to the load. slightly oblique to the base. Directly with a shorter arm or. behind it is a pair of wheels that are freely rotatable and mounted on each side of the cart. The wheels are co-axial. As the load is being loaded, the liner is generally located at the base with at least its leading edge so that the load can be pushed against it. Then, they tilt the trolley so that the load or the load rests on the longer arm of the frame. The dominant component of the weight of the load is assumed by the wheels, and the user therefore faces only a smaller proportion of the normal load. Although the load can generally be mounted on a frame, most universal carts are not equipped with fasteners. Such trolleys are massive, robust and relatively heavy and mostly suitable for use in industry and warehouses, and as a rule, only by persons who are well versed in

In particular, such trolleys do not seem to be suitable for transportation with other vehicles, especially when loaded.

Še nadalje je iz WO 84/02499 znan ročni voziček, ki sestoji iz razstavljivega ogrodja, na katerega enem koncu je na voljo ročaj, na drugem koncu pa sta nameščeni soosni kolesi. Na ogrodju, ki zaradi svoje zasnove tudi sicer ne deluje zelo togo, so nameščene vzdolž ogrodja drsno premakljive sani, na njih pa vakuumska prijemala. V območju koles sta na voljo konzoli, ki naj bi služili za podporo tovora med vožnjo. Voziček je sicer domiselno zasnovan in kot kaže primeren za prevažanje trdnih bremen, najverjetneje kovčkov in podobnih. PO drugi strani pa je voziček očitno razmeroma kompliciran in ga zato v zadoviljivi kakovosti in togosti nikakor ni mogoče izdelati na cenen način. Zavarovanje tovora proti prevračanju s pomočjo vakuumskih prijemal se v primeru bremen s hrapavo ali neravno ali umazano površino lahko zelo hitro izkaže kot docela nesprejemljivo. Še zlasti v primeru plinskih jeklenk in podobnih bremen, kjer kaže zaradi varnostnih zahtev in konec koncev vendarle tudi zaradi dokajšnje teže bremena možnost prevračanja tovora med prevažanjem kjer je le mogoče vnaprej izključiti.Further, from WO 84/02499, a hand trolley is known, consisting of a disassembled frame with a handle at one end and coaxial wheels mounted at the other end. On the frame, which does not work very rigidly due to its design, sliding movable sleds are mounted along the frame and vacuum grips are mounted on them. There are brackets in the wheel area that are designed to support the load while traveling. The trolley is imaginatively designed and seems to be suitable for carrying heavy loads, most likely suitcases and the like. The trolley, on the other hand, is obviously relatively complicated and therefore cannot be produced in an inexpensive way in satisfactory quality and rigidity. Vacuum overload securing by vacuum grips can very quickly be totally unacceptable in the case of loads with rough or uneven or dirty surfaces. Especially in the case of gas cylinders and similar loads, where, due to safety requirements and, ultimately, due to the weight of the load, the possibility of tipping the load during transport is possible where it can be excluded in advance.

Po izumu je ročni voziček, ki sicer obsega cevasto ogrodje, ki je zasnovano v obliki črke U in sestoji iz dveh med seboj vzporednih krakov kot tudi iz med slednjima nahajajočega se ročaja, pn čemer je na skrajnih koncih omenjenih krakov nameščena os s kolesoma, izpopolnjen na ta način, da je v osrednjem območju ogrodja predviden vzdolž omenjenih krakov proti sili vzmeti premakljiv in z zapahom opremljen drsnik, Razen tega je na vsakem od omenjenih krakov na njegovem skrajnem končnem območju na voljo vsaj po en konzolni nosilec. V osrednjem območju ogrodja je nameščena prečka, ki je predvidena za držanje vzmeti, slednja pa je po drugi strani koncu pripeta na drsnik. Razen tega sta med omenjeno prečko in ročajem na vsakem kraku ogrodja na voljo po dva zatiča, s pomočjo katerih je omejeno premikanje drsnika vzdolž krakov ogrodja. Drsnik sestoji iz prečke, ki je s pomočjo drsnih puš ali podobnih drsnih sredstev premakljiva vzdolž krakov ogrodja med vsakokrat sosednjima zatičema na vsakem od pripadajočih krakov, in je razen tega opremljen z ročico ter z vzmetjo vlečen v smeri proti osi. Na omenjenem drsniku je prednostno v osrednji razporeditvi na voljo v smeri glede na voziček kot celoto naprej štrleč zapah, ki je opremljen s poševnino, ki poteka med bližje vsakokrat pripadajočemu kraku ogrodja nahajajočim se daljšim robom in od vsakokrat pripadajočega kraka ogrodja bolj oddaljenim krajšim robom v zapahu predvidene zajede. Vsak od konzolnih nosilcev na skrajnih koncih krakov ogrodja je prednostno zasnovan kot ploščat trak, ukrivljen v obliko črke U, pri čemer je en njegov krak zasukan okoli svoje vzdolžne osi v položaj pravokotno glede na preostali krak in opremljen s skoznjo luknjo, zahvaljujoč kateri je - kadar je vstavljen v svetlino vsakokrat pripadajočega cevastega kraka ogrodja vozička - skozenj vstavljena os z na sebi nameščenima kolesoma. Samo ogrodje vozička je prednostno torej zasnovano iz okrogle cevi, ki je s stiskanjem in krivljen jem preoblikovana nekako v obliko črke U, in sicer na ta način, da je med vsakim od med seboj vzporednih krakov in glede na slednja pravokotno potekajočim ročajem na voljo stisnjeno in nekako v obliko črke V ukrivljeno območje. Nadalje je za voziček po izumu značilno, da je na krakih ogrodja bližje ročaju nahajajoči se par zatičev izrazito podaljšan in štrli v smeri nazaj in pravokotno tako glede na kraka ogrodja kot tudi glede na ročaj ogrodja, pri čemer skupaj s kolesoma služi kot podpora ogrodja v položaju, kadar se slednje nahaja vsaj v bistvu vzporedno s podlago.According to the invention, a hand trolley, which otherwise comprises a tubular frame, which is U-shaped and consists of two parallel arms as well as a handle located between them, whereby an axle with wheels is provided at the extreme ends of said arms. in such a way that, in the central area of the frame, there is a movable and lockable slider provided along said force bars, in addition, at least one cantilever bracket is provided at each end of said frame at its extreme end region. In the central area of the frame there is a crossbar which is designed to hold the spring, the latter on the other end being attached to the slide. In addition, two pins are provided between said bar and handle on each frame arm, which restrict the movement of the slider along the frame arms. The slider consists of a crossbar which, by means of sliding bushings or similar sliding means, is movable along the arms of the frame between the adjacent pins on each of the adjacent arms, and is further provided with a lever and with a spring drawn in an axial direction. On the slider, in a central arrangement, it is preferably provided in a direction relative to the trolley as a whole, a projecting latch, which is provided with a slant extending between the longer edge of each frame and the longer edge of the frame corresponding to each frame. the bite of the intended bite. Each of the cantilever brackets at the far ends of the frame arms is preferably designed as a U-shaped curved strip, with one of its arms rotated about its longitudinal axis in a position perpendicular to the remaining arm and provided with a through hole, by virtue of which - when inserted into the brightness of the respective tubular arm of the trolley body - through it an inserted axle with wheels mounted on it. Thus, the cart body itself is preferably formed of a round tube, which is shaped and shaped into a U-shape by compression and bending, in such a way that compressed arms are provided between each of the two parallel arms and with respect to the latter. and somehow in the shape of a letter V curved area. Furthermore, the trolley according to the invention is characterized by the fact that on the arms of the frame closer to the handle, the locating pair of pins is markedly extended and protruding in the direction back and perpendicular to the frame arms as well as to the frame handle, and together with the wheels serves as a support for the frame in position where the latter is at least substantially parallel to the substrate.

Ročni voziček je izveden iz ogrodja 10, na katerem je nameščen drsnik 20 z zapahom 27.The hand trolley is made of a frame 10 on which a slider 20 with a latch 27 is mounted.

Ogrodje 10 je prednostno izvedeno kar iz okrogle kovinske cevi, prekrivljene v obliko črke U. V danem primeru ogrodje 10 sestoji iz med seboj vzporednih krakov 11, 12 in med slednjima nahajajočega ročaja 13 za upravljanje vozička. Vogalni območji 13', 13 med krakoma 11, 12 in omenjenim ročajem 13 sta prednostno izvedeni kot stisnjeni in v obliko črke V prekrivljeni območji, zahvaljujoč katerima je na enostaven način bistveno izboljšana togost celotnega ogrodja 10.The frame 10 is preferably made of a circular metal tube overlaid in the U-shape. In this case, the frame 10 consists of parallel arms 11, 12 and a cart handle 13 located between them. The corner regions 13 ', 13 between the arms 11, 12 and said handle 13 are preferably designed as compressed and letter-shaped, overlapped areas, which significantly improve the rigidity of the entire frame 10 in a simple manner.

Nekako v osrednjem območju 14 ogrodja 10 je med krakoma 11, 12 na voljo prečka 15, med slednjo in ročajem 13 pa sta na vsakem kraku 11, 12 na hrbtni strani na voljo po dva glede na ogrodje 10 v smeri nazaj štrleča zatiča 16', 16 in 17', 17. Zatiča 16', 16, ki sta od ročaja 13 bolj oddaljena, sta namenjena zgolj za omejevanje hoda drsnika 20. Preostala dva zatiča 17', 17 sta bistveno daljša in razen za omejevanje hoda drsnika 20 služita tudi kot podpori za držanje ogrodja 10 na odmiku od podlage, kadar je voziček položen v vsaj približno vodoraven položaj, namreč vsaj v bistvu vzporedno s podlago, hkrati pa v tem položaju preprečujeta tudi njegovo premikanje.Somehow, in the central region 14 of the frame 10, there is a crossbar 15 between the arms 11, 12, and between the latter and the handle 13 there are two at each back 11, 12 in relation to the frame 10 in the rearwardly projecting pin 16 '. 16 and 17 ', 17. The pins 16', 16, which are farther from the handle 13, are intended solely to limit the stroke of the slider 20. The remaining two pins 17 ', 17 are substantially longer and, except for limiting the stroke of the slider 20, also serve as the supports for holding the frame 10 at a distance from the base when the trolley is positioned in at least approximately horizontal position, at least substantially parallel to the ground, but also prevent its movement in this position.

Na skrajnih koncih krakov 11, 12 je na vsakem od slednjih na voljo po ena skoznja luknja 18', 18. Omenjeni luknji 18', 18 sta soosni, skozi njiju pa je vstavljena os 19, na kateri sta prednostno kar prostovrtljivo nameščeni kolesi 5', 5.At the far ends of the arms 11, 12, one through hole 18 ', 18 is provided on each of the latter. The said holes 18', 18 are coaxial, through which an axis 19 is inserted, on which the 5 'wheels are preferably mounted. , 5.

Razen tega je na obeh skrajnih koncih kot rečeno cevasto zasnovanih krakov 11, 12 cevastega ogrodja 10 v vsakega od krakov 11, 12 vstavljen po en konzolni nosilec 1, 2. Prednostna izvedba takega nosilca 1, 2 je posebej prikazana na sl. 6 inIn addition, at the two extreme ends, as said tubular-shaped arms 11, 12 of the tubular frame 10, one cantilever bracket 1, 2 is inserted into each of the arms 11, 12. A preferred embodiment of such bracket 1, 2 is shown separately in FIG. 6 in

7. Vsakokraten nosilec 1, 2 je izveden iz ploščatega gradiva, npr. iz ploščatega vroče valjanega jeklenega traku, ki je ukrivljen v obliko črke U. Eden od omenjenih krakov Γ, 1, v danem primeru krak Γ, je prekrivljen oz. zasukan okoli svoje vzdolžne osi v položaj pravokotno na preostali krak 1. Na tem prekri vij enem kraku 1 je na vol jo skoznja luknja 1'.7. The respective carrier 1, 2 is made of flat material, e.g. flat, hot-rolled steel strip, which is curved in the shape of the letter U. One of the mentioned arms Γ, 1, in this case the arm Γ, is overlapped or folded. rotated about its longitudinal axis in a position perpendicular to the remainder of the limb 1. Thereupon, through the screw of one limb 1 there is a hole through the hole 1 '.

Zahvaljujoč tovrstni zasnovi nosilcev 1, 2 je možno vsakega od slednjih vstaviti v svetlino na skrajnem koncu vsakokrat pripadajočega kraka 11,12 ogrodja 10 (sl. 5) in nato skozi skoznjo luknjo 1' vstaviti os 19 ter zatem na slednjo namestiti kolesi 5', 5. V smislu še nadaljnjega izboljšanja togosti celotnega ogrodja 10 je lahko tudi prednostno, če je na osi 19 med obema krakoma 11,12 ogrodja 10 nameščen še na skici sicer neprikazan distančnik, ki je lahko na karseda preprost način izveden kar kot na primemo dolžino odrezana cev.Thanks to this type of mounting brackets 1, 2 it is possible to insert each of the latter into the luminaire at the far end of the respective arm 11,12 of the frame 10 (Fig. 5), and then insert a shaft 19 through the hole 1 'and then mount the wheels 5' thereon. 5. In order to further improve the rigidity of the entire frame 10, it may also be advantageous if, on the axis 19 between the two arms 11,12 of the frame 10, an otherwise not shown spacer is mounted on the sketch, which can be made in as simple a way as possible at a given length cut off pipe.

Na ogrodju 10. natančneje na njegovih krakih 11, 12, je v osrednjem območju 14, natančneje med prej omenjenimi zatiči 16', 16 in 17', 17, nameščen drsnik 20. Ta je v osnovi izveden kot prečka 21, na katere koncih 2Γ, 21 sta na voljo drsni puši 22, 23 ali podobni sredstvi za omogočanje premikanja drsnika 20 po zunanji površini obeh krakov 11, 12 ogrodja 10.On the frame 10. More specifically on its legs 11, 12, in the central region 14, more precisely between the previously mentioned pins 16 ', 16 and 17', 17, there is a slider 20. This is basically made as a crossbar 21, at which ends 2Γ , 21, sliding sleeves 22, 23 or similar means are provided to allow the slider 20 to move along the outer surface of the two arms 11, 12 of the frame 10.

Drsnik 20 je opremljen z vzmetjo 24, ki je v danem primeru izvedena kot natezna vijačna vzmet in ki je po eni strani pripeta na prej omenjeno prečko 15 med krakoma 11,12 ogrodja 10, po drugi strani pa na samo prečko 21, in sicer v danem primeru s pomočjo skoznje luknje 26, ki je na voljo na ustrezni lokaciji na prečki 21. Prečka 21 je opremljena z ročico 25, ki služi za premikanje drsnika 20 proti sili omenjene vzmeti 24 v območju od zatičev 16', 16 proti zatičema 17', 17 in obratno. Razen tega je v osrednjem območju drsnika 20 oz. natančneje njegove prečke 21 na vol jo zapah 27, ki je viden na sl. 1 in 3, podrobneje pa je prikazan tudi na sl. 4.The slider 20 is provided with a spring 24, which is optionally made as a tensile screw spring, which is attached on the one hand to the aforementioned crossbar 15 between the arms 11,12 of the frame 10 and, on the other, to the crossbar 21 itself, in as the case may be, through a hole 26 provided at a suitable location on the rung 21. The rung 21 is provided with a lever 25 which serves to move the slider 20 against the force of said spring 24 in the range of the pins 16 ', 16 towards the pins 17' , 17 and vice versa. In addition, there are 20 or more sliders in the central slider area. more specifically, its bars 21 on the shaft latch 27 which is visible in FIG. 1 and 3, and is shown in more detail in FIGS. 4.

Zapah 27 drsnika 20 obsega zajedo 28. ki je prednostno trapezna in obsega daljši notranji naslonski rob 28', ki v danem primeru poteka vzporedno s krakoma 11, 12 ogrodja 10, in krajši zunanji naslonski rob 28 ki v danem primeru poteka vzporedno s prej omenjenim robom 28'. Med omenjenima roboma 28', 28 je na voljo poševnina 28'.The latch 27 of the slider 20 comprises a lug 28. which is preferably trapezoidal and comprises a longer inner abutment edge 28 'extending in parallel with the arms 11, 12 of the frame 10, and a shorter outer abutment lip 28 extending in parallel with the aforementioned. edge 28 '. A slant 28 'is available between said edges 28', 28.

Ko je ročni voziček sestavljen, sta konzolna nosilca 1, 2 vstavljena v svetlinah krakov 11, 12 ogrodja 10, s čimer je preprečeno njuno premikanje v katerikoli smeri. Zahvaljujoč sili vzmeti 24, vpete med prečko 15 ogrodja 10 in prečko 21 drsnika 20, je drsnik 20 povlečen v svojo skrajno spodnjo lego oz. karseda blizu prečki 15 oz. osi 19 s kolesoma 5', 5, pri čemer je v tem položaju naslonjen na zatiča 16', 16. Voziček v takšnem stanju lahko bodisi prenašamo ali ga prevažamo v vozilu. Lahko ga vsekakor npr. tudi primemo za ročaj 13 in ga zahvaljujoč kolesoma 5', 5 prepeljemo na mesto, kjer je za natovarjanje pripravljena plinska jeklenka ali podobna posoda.When the trolley is assembled, the cantilever brackets 1, 2 are inserted in the luminaires of the arms 11, 12 of the frame 10, which prevents them from moving in any direction. Due to the force of the spring 24 clamped between the frame 15 of the frame 10 and the bar 21 of the slider 20, the slider 20 is pulled into its extreme lower position, respectively. as close as possible to the 15 oz. axles 19 with wheels 5 ', 5, in which position it is rested on the pin 16', 16. The trolley in this state can either be carried or carried in the vehicle. It can definitely be e.g. also grip handle 13 and, thanks to the 5 ', 5 wheels, transport it to a place where a gas cylinder or similar container is prepared for loading.

Kot je znano, je plinska jeklenka pod dnom opremljena z obročem, ki služi kot podstavek, razen tega pa je obroč na voljo tudi na njenem zgornjem koncu in služi kot ročaj.As is known, the gas cylinder under the bottom is provided with a ring that serves as a base, except that the ring is also available at its upper end and serves as a handle.

Ko takšno jeklenko - polno ali prazno - nagnemo, lahko konzolna nosilca 1, 2 sežeta pod omenjeni spodnji obroč jeklenke, tako da od okvira 10 bolj oddaljeni krak 1 (po sl. 6) naleže na notranjo površino spodnjega obroča jeklenke. S povlečenjem ročice 25 drsnika 20 vozička v smeri navzgor oz. proti ročaju 13 in torej proti sili vzmeti 24 dosežemo premik drsnika 20 v smeri proti ročaju 13. Ta premik je mogoč vse do zatičev 17'. 17. S premikom drsnika 20 pa se v smeri proti ročaju 13 premakne tudi zapah 27. Z zavihtenjem vozička oz. krakov 11, 12 ogrodja 10 v smeri proti jeklenki zatem zlahka dosežemo, da se zajeda 28 zapaha 27 nahaja neposredno nad zgornjim obročem vsakokratne plinske jeklenke ali podobne posode. Po sprostitvi ročice 25 vzmet 24 pritegne prečko 21 drsnika 20 in premakne 20 drsnik v smeri proti prečki 15 oz. proti osi 19. Pri tem zgornji obroč vsakokratne plinske jeklenke ali podobne posode uprime v zajedo 28 zapaha 27 drsnika 20 vozička. Za nameček poševnina 28' ustvari primemo komponento sile, ki jeklenko vseskozi pritiska v smeri proti krakoma 11, 12 ogrodja 10. S pomočjo ročaja 13 lahko voziček nagnemo in jeklenko ali podobno posodo prepeljemo kamor je pač potrebno. Okvir 10 skupaj z jeklenko ali podobno posodo, vpeto med konzolna nosilca 1, 2 in zapah 27, lahko (po sl. 3 v smeri urinih kazalcev) tudi zavihtimo v vodoraven položaj, torej v položaj, ko sta kraka 11, 12 ogrodja 10 vzporedna s podlago. V tem primeru je ogrodje 10 po eni strani podprto s kolesoma 5', 5. po drugi strani pa z zatičema 17', 17, pri čemer je voziček zahvaljujoč zatičema 17', 17 zavarovan proti vsakršnemu premikanju. To je še zlasti ugodno v primeru prevažan ja plinske jeklenke ali podobne posode na primerni ravni podlagi v vozilu, npr. na dnu prtljažnega prostoraWhen tilting such a cylinder - full or empty -, the cantilever brackets 1, 2 can extend below said lower ring of the cylinder so that the more distant arm 1 (according to Fig. 6) fits on the inner surface of the lower ring of the cylinder. By pulling the lever 25 of the trolley 20 of the trolley upwards or. towards the handle 13 and therefore against the force of the spring 24, the slide 20 is moved in the direction towards the handle 13. This movement is possible up to the pins 17 '. 17. By moving the slider 20, however, the latch 27 moves in the direction of the handle 13. the legs 11, 12 of the housing 10 in the direction of the cylinder can then be easily reached so that the latch 28 of the latch 27 is located directly above the upper ring of the respective gas cylinder or similar container. After releasing the lever 25, the spring 24 engages the bar 21 of the slider 20 and moves the slider 20 toward the 15 or 12 bar. 19. The upper ring of the respective gas cylinder or similar container is supported by the latch 28 of the latch 27 of the slider 20 of the trolley. For example, the bevel 28 'creates a gripping force component that presses the cylinder all the way towards the arms 11, 12 of the frame 10. With the help of the handle 13, the trolley can be tilted and the cylinder or similar container transported where necessary. The frame 10 together with the cylinder or similar container clamped between the cantilever brackets 1, 2 and the latch 27 can (in Fig. 3 clockwise) also be rotated to a horizontal position, ie to a position where the arms 11, 12 of the frame 10 are parallel. with the base. In this case, the frame 10 is supported, on the one hand, by the wheels 5 ', and 5. on the other, by the pins 17', 17, and the trolley is secured against any movement thanks to the pins 17 ', 17. This is especially advantageous in the case of transporting a gas cylinder or similar container on an appropriate level basis in a vehicle, e.g. at the bottom of the luggage compartment
