Description

Vynález sa 'týká zdvíhacieho vozíka, najma pre kuchyně, o nosnosti do 70 kg, použiteíného v závodných, školských a iných kuchyniach.The invention relates to a lift truck, in particular for kitchens, with a load capacity of up to 70 kg, to be used in racing, school and other kitchens.

Doterajší stav techniky pri preprave potravin v kuchyniach tam, kde nie sú linky, rieši přepravu vozíkmi bez možnosti zdvíhania plošiny na vyrovnanie rozdielnych výšok kuchyňských zariadení. Zdvihanie tažkých nádob je ručné a teda namáhavé.BACKGROUND OF THE INVENTION In the transport of food in kitchens where there are no lines, the prior art solves transportation by trolleys without the possibility of lifting the platform to compensate for different heights of the kitchen appliances. Lifting heavy containers is manual and therefore laborious.

Žalej sú známe vozíky, ktoré zdvíhajú plošiny vertikálně, či už mechanickým spSsobom, alebo hydraulickým, sú však opatřené nosnými stípmi, ktoré zavadzajú pri manipulácii s bremenami a nevyhovujú pri obsluhe jedným pracovníkom.Still further, there are known trucks that lift the platforms vertically, either mechanically or hydraulically, but are provided with load-bearing columns which obstruct the handling of loads and do not suit one operator to operate them.

Tieto nevýhody odstraňuje zdvíhací vozík pre kuchyně podía vynálezu, pozostávajúci z nosnej plošiny, převodového paralelogramu, zdvíhacieho ústrojenstva a rámu opatřeného otočnými kolieskami, ktorého podstata spočívá v tom, že nosná plošina je vyhotovená vo formě konzoly, na jej zvislej .časti su výkyvné, uchytené pravé konce převodového zdvojeného paralelogramu, ktorého íavé.konce sú výkyvné spojené s konzolou na nosnom ráme vozíka, pričom hydraulický mechanizmus je opatřený pákou pre zdvíhanie nosnej plošiny a spúštadlom, pričom horné tiahlo paralelogramu je výkyvné spojené so zdvíhacím valcom hydraulického mechanizmu v rozpatí jednej čtvrtiny až jednej třetiny jeho dížky.These drawbacks are eliminated by the kitchen lift according to the invention, consisting of a support platform, a gear paralelogram, a lifting device and a frame provided with swivel castors, the main feature of which is that the support platform is in the form of a bracket. the right ends of the geared double parallelogram, the left ends of which are pivotally connected to a bracket on the carrier frame of the carriage, the hydraulic mechanism being provided with a lever for lifting the carrier and a trigger, one third of his length.

Výhodou zdvíhacieho vozíka podía vynálezu je, že umožňuje manipuláoie s tažkými kuchyňskými nádobami s horúcimi potravinami vo všetkých smeroch horizontálnej roviny.An advantage of the lift truck according to the invention is that it allows to handle heavy kitchen containers with hot food in all directions of the horizontal plane.

205 397 ako aj vo vertikálnem smere.. Vozík má možnost skladat potraviny, vamice z plošiny nákladného auta, čo je obzvlášť namáhavá práca.205 397 as well as in the vertical direction. The truck has the option of storing groceries, shells from the truck platform, which is a particularly arduous job.

Výrazné sa znižuje obarenia horúcami tekutinami a zvyšuje sa bezpečnost pri práci v kuchyni. Zároveň sa zrýchíuje pohyb přepravovaných potravin pri ioh príprave á rozvoze, odstraňuje sa tažká práca a šetria sa pracovně sily. Salšou výhodou zdvíhacieho vozíka podía vynálezu je, že pre svoje rozměry-si nevyžaduje vačšie priechodné priestory ako potřebuje člověk. Vozík sa ,dá použit i v cukrárskom priemysle-pri odbere nádob z miešačiek pre vylievanie poliev na zákusky, čo je dosial pre jej namáhavost výlučné mužská práca. Vozík je hygienický a dobré umývateíný.Significantly reduced scalding from hot liquids and increased safety when working in the kitchen. At the same time, the movement of transported food is accelerated during preparation and distribution, heavy work is eliminated and labor is saved. A salerary advantage of the lift truck according to the invention is that, because of its dimensions, it does not require larger passage spaces than a human needs. The trolley can also be used in the confectionery industry by taking containers from mixers for pouring desserts, which until now has been exclusively male labor for its labor. The trolley is hygienic and well washable.

Jeden z príkladov vyhotovenia zdvíhaoieho vozíka podía vynálezu je znázorněný na priloženom výkrese, v ktorom obr. 1 představuje nárysný a obr. 2 půdorysný pohíad na uvedený vozík.One example of an embodiment of a lift truck according to the invention is shown in the accompanying drawing, in which FIG. 1 is a front view and FIG. 2 is a plan view of said cart.

Hlavně časti zdvíhaoieho vozíka sú nosná plošina 1 (obr. 2) spojená s konzolou 2 (obr. 1) s převodovým zdvojeným paralelogramora £, ktorý je spojený kíbovite s konzolou 4 a je opatřený výkyvným hydraulickým valcom £, hydraulickým mechanizmom 6, ktoré nesie nosný rám 2 opatřený štyrmi otočnými kolieskami 8. Hydraulický.mechanizmu^ & je ovládaný šlapacou nožnou pákou £ pre zdvíhanie plošiny 1 (obr. 2), ktorá má nožné spúštadlo 10 pre spúštanie nosnej plošiny 1 a regulačnú skrutku.11 pre nastavenie rychlostí spúštania břemena. Vozík je riadený ručně držiakom 12.Mainly the parts of the lift truck are a support platform 1 (Fig. 2) connected to a bracket 2 (Fig. 1) with a geared double parallelogramor 6 which is articulated to the bracket 4 and is provided with a pivotable hydraulic cylinder 6, a hydraulic mechanism 6 supporting the support The frame 2 is provided with four swivel castors 8. The hydraulic mechanism 8 is operated by a pedal foot 5 for lifting a platform 1 (FIG. 2) having a foot trigger 10 for lowering the support platform 1 and a control screw 11 for adjusting the load lowering speeds. The trolley is controlled manually by the holder 12.

Uvedený zdvíhací vozík má široké možnosti uplatnenia i mimo činnosti, pre kíoíé je určený. Može sa použit pre skladanie nákladov z plošin nákladných aut, čo sa robí dosial ručně před každým obchodom. V sklade može byt využitý ako zdvíhacia plošina pre pracovníka na nakladanie potravin do vyšších regálov. Jeho využitie je vo výrobných. závodoch, v sklade na přepravu súčiastok, kde nie je zavedená ihá mechanizácia.Said forklift has a wide range of applications outside the activity for which it is intended. It can be used to stack loads from truck platforms, which is done by hand before each shop. In the warehouse it can be used as a lifting platform for a worker for loading food into higher shelves. Its use is in production. plants, in the warehouse for the transport of parts where there is no direct mechanization.
