Description
Higienski stekleni pokrov hladilnih pultov za svežo hrano Področje tehnikeHygienic glass cover for refrigerated counters for fresh food Field of the technique
Tehnična rešitev se nanaša na higienski stekleni pokrov hladilnih pultov za svežo hrano, ki ga sestavlja navpično pomični stekleni poklop, ki je s pomočjo pomičnega sistema nameščen nad notranjim prostorom hladilnega pulta za svežo hrano.The technical solution relates to a hygienic glass cover for fresh food refrigerators, consisting of a vertical sliding glass cover, which is mounted above the interior of the refrigerator counter for fresh food using a movable system.
Znano stanje tehnikeA known state of the art
Za ponujanje, prodajo ali tudi za samopostrežno serviranje sveže hrane, predvsem jedi iz svežih sestavin, ki se hitro pokvarijo, kot so npr. solate, mlečni izdelki, sušeno meso ipd., so trgovine s sadjem in zelenjavo, menze, bifeji in drugi podobni obrati opremljeni z različnimi hladilnimi vitrinami in pulti. Ti pulti in vitrine so v različnih postavitvah zaprti s prozornimi, najpogosteje steklenimi pokrovi v obliki krilnih ali stransko pomičnih poklopov, pokrovov ali sten. Takšna oprema je znana tudi iz patentnih listin, in sicer npr. iz listin EP 2512296 in EP 1427315 ali iz čeških patentov s skrajšanim trajanjem št. prijave CZ 14299 in št. prijave CZ 17797 U. Z vidika funkcionalnosti, manipulacije in estetike so priročnejši navpično pomični stekleni poklopi, ki so namenjeni predvsem za hladilne pulte za shranjevanje sveže hrane večjih dimenzij. Takšni poklopi oziroma celotni pulti so znani na primer iz ponudbe proizvajalcev ENOFRIGO, ARNEG ali AICHINGER. Vendar, pri teh napravah lahko pri dviganju oziroma spuščanju steklenih poklopov v vrsti primerov pride predvsem do križanja njihovih postavitev, do nepravilnosti v njihovem pomikanju in posledično do težav pri njihovi uporabi.For offering, selling or for self-service fresh food, especially dishes from fresh ingredients that are quickly broken down, such as, for example, salads, dairy products, dried meat, etc., fruit and vegetable stores, canteens, buffets and other similar plants are equipped with various refrigerating showcases and counters. These counters and showcases are sealed in various layouts with transparent, most often glass lids in the form of wings or side movable covers, lids or walls. Such equipment is also known from patent documents, e.g. from EP 2512296 and EP 1427315, or from Czech short-term patents no. applications CZ 14299 and no. applications CZ 17797 U. From the aspect of functionality, manipulation and aesthetics, the more vertically movable glass covers are more convenient, which are intended primarily for refrigerated counters for storing fresh foods of larger dimensions. Such covers or complete counters are known, for example, from the offer of ENOFRIGO, ARNEG or AICHINGER manufacturers. However, in these devices, in the case of raising or lowering of glass coverings, in a number of cases, it may occur, above all, to cross their layouts, to the irregularities in their movement, and, consequently, to difficulties in their use.
Cilj predlagane tehnične rešitve je zato po eni strani odstranitev navedenih težav in po drugi strani izboljšanje funkcionalnosti navpično pomičnih steklenih pokrovov hladilnih posod pri tovrstni opremi.The aim of the proposed technical solution is therefore to eliminate these problems on the one hand and, on the other hand, to improve the functionality of the vertical sliding glass roofs of the cooling containers in such equipment.
Bistvene značilnosti nove tehnične rešitveEssential features of the new technical solution
Ta cilj do znatne mere izpolnjuje higienski stekleni pokrov hladilnih pultov za svežo hrano, ki ga sestavlja navpično pomičnistekleni poklop, ki je s pomočjo sistema pomika nameščen nad notranjim prostorom hladilnega pulta skladno s predlagano tehnično rešitvijo, katere bistvo je v tem, daje sistem pomika steklenega poklopa sestavljen iz vsaj enega para nasproti umeščenih vodilnihvozičkov, ki sta opremljena s poševno nameščenimidrsnimi kolesci, ki se z nastavljivim tlakom prilegajo poševnim drsnim površinam njihovih navpičnih tirnic pomika. Vodilna vozička sistemov pomika steklenega poklopa sta pri temv gibanju medsebojno povezana preko sestava prenosnih škripcev z vsaj enim kablom.This objective satisfies the hygienic glass cover of fresh food refrigerating hoods consisting of a vertical movable glass cover which is positioned above the interior of the cooling counter with the shaft system in accordance with the proposed technical solution, the essence of which is that the system of displacement of the glass a lid made up of at least one pair of opposite-mounted guides which are fitted with obliquely mounted helical rollers that fit with the adjustable pressure to the oblique sliding surfaces of their vertical displacement rails. The guide trunks of the glass cover shaft systems are interconnected in this movement through the assembly of portable pulleys with at least one cable.
Bistvo tehnične rešitve je nadalje v tem, da je sistem pomika steklenega poklopa nameščen znotraj nasproti ležečih stranskih navpičnih opor okviija zgornje konstrukcije pulta za svežo hrano, v katerih je za nastavitev tlaka vodilnih vozičkov na njihove poševne drsne površine v eni stranski opori umeščen vsaj en nastavljiv vodilni voziček, v nasprotni stranski opori pa vsaj en nasproti ležeči vodilni voziček. Nastavljivi vodilni voziček je za nastavljanje tlaka pri tem opremljen z vsaj eno drsno pušo, usmeijeno pravokotno na stransko steno steklenega poklopa, v katero je vstavljen drsni vložek, ki z enim svojim koncem prehaja skozi stransko steno steklenega poklopa, na katero je z notranje strani pritrjen s pritrdilnimi vijaki. Z drugim koncem ta drsni vložek prehaja skozi telo nastavljivega vodilnega vozička, na tem mestu pa je opremljena s prednapeto vzmetjo in njenim nastavitvenim vijakom. Nasproti ležeči vodilni voziček je opremljen le s podporno pušo, s katero se opira na drugo stransko steno steklenega poklopa, na katero je oporna puša z notranje strani ravno tako pritrjena s pritrdilnimi vijaki. Velikost tlaka tega nasproti ležečega vozička na njegove poševne drsne površine je pri tem dana z nastavljeno velikostjo tlaka v nastavljivem vodilnem vozičku, saj se nastavljena velikost tlaka v nastavljivem vodilnem vozičku prenaša na nasproti ležeči voziček preko telesa steklenega poklopa, s katerim sta oba vozička povezana.The essence of the technical solution further lies in the fact that the glass cover shaft system is located inside the opposite side vertical support frame of the upper construction of a fresh food counter in which, for adjusting the pressure of the guide carriages to their oblique sliding surfaces in one side support, at least one adjustable a leading trolley, and at least one opposite leading trolley in the opposite side support. The adjustable guide trolley is provided with at least one sliding sleeve arranged perpendicular to the lateral wall of the glass cover in which a sliding insert is inserted which, with one end, passes through the side wall of the glass cover, which is attached from the inside with fixing screws. At the other end, this sliding insert passes through the body of the adjustable guide carriage, and is fitted with a prestressing spring and its adjusting screw. The opposite leading trolley is only fitted with a support sleeve, which rests on the other side wall of the glass cover, on which the support sleeve from the inner side is also fixed with the fixing screws. The pressure of this opposite trolley on its oblique sliding surfaces is given with the adjusted pressure in the adjustable guide trolley, as the set pressure in the adjustable guide trolley is transmitted to the opposite trolley over the body of the glass cover, with which both trolleys are connected.
Izvedba z zgornjo konstrukcijo z okvirjem je koristna predvsem s konstrukcijskega vidika, po potrebi pa je mogoče sistem pomika higienskega steklenega pokrova skladno s tehnično rešitvijo namestiti tudi na stranice pulta za shranjevanje sveže hrane, pod njegovo vrhnjo površino. Skupno število vodilnih vozičkov tega sistema pomika je v obeh primerih odvisno od dimenzij pulta za svežo hrano in temu primerne velikosti steklenega poklopa, po potrebi pa je mogoče tudi vse vodilne vozičke opremiti z zgoraj opisanim mehanizmom za nastavljanje tlaka le-teh na njihove poševne drsne površine, tj. s pomočjo drsnih vložkov s prednapetimi vzmetmi in nastavitvenimi vijaki.The design with the upper structure with the frame is useful primarily from the constructional point of view, and, if necessary, the system of moving the hygienic glass cover in accordance with the technical solution can also be installed on the sides of the counter for storage of fresh food, under its top surface. The total number of guide wheels of this shift system in both cases depends on the dimensions of the fresh food table and the appropriate size of the glass cover, and, if necessary, all the guide trolleys can be fitted with the above-described mechanism for adjusting the pressure of these on their oblique sliding surfaces , ie. with sliding inserts with prestressed springs and adjusting screws.
Bistvo tehnične rešitve je tudi v tem, daje sistem pomika steklenega poklopa nadalje opremljen tudi s protiutežmi z nastavljivo maso za uravnovešanje mase steklenega poklopa, ki so opremljene z elektromagnetom za ohranjanje položaja steklenega poklopa v zgornjem položajupo njegovem dvigu. V okvirju zgornje konstrukcije je pri tem umeščen senzor gibanja oseb v prostoru za serviranje jedi za krmiljenje dovoda električnega toka v elektromagnet in za samodejno spuščanje steklenega poklopa v spodnji položaj, če senzor ne zazna nobenega gibanja v predvidenem intervalu, elektromagnet pa je (lahko) tudi opremljen z vzmetnim blažilcem in povezan s prekinitvenim stikalom dovoda električnega toka za ročno spuščanje steklenega poklopa v spodnji položaj. Ta vzmetni blažilec omogoča v obsegu svojega hoda premik protiuteži zaradi povzročenega ročnega tlaka na stekleni poklop in izklop dovoda električnega toka v elektromagnet s prekinitvenim stikalom.The essence of the technical solution also lies in the fact that the hinged glass hinge system is further provided with counterweights with an adjustable mass for balancing the weight of the glass hood which are fitted with an electromagnet to maintain the position of the glass hood in its upper position. In the frame of the upper structure there is a sensor of movement of persons in the room for serving dishes for controlling the flow of the electric current into the electromagnet and for automatically lowering the glass cover into the lower position if the sensor detects no movement at the predetermined interval and the electromagnet can fitted with a spring damper and connected to the power supply interruption switch to manually lower the glass cover into the lower position. This spring shock absorber allows, in the extent of its course, the displacement of the counterweight due to the applied manual pressure on the glass cover and the shutdown of the electric current in the electromagnet with the breaker switch.
Za običajno ročno odpiranje in morebitno ročno zapiranje higienskega steklenega pokrova pultov za svežo hrano skladno s predlagano tehnično rešitvijo je mogoče uporabiti komercialno dostopne ročke ali druga prijemala, ki se uporabljajo tudi za druge enostavne krilne ali stransko pomične pokrove in poklope. Lahkoten in gladek pomik pri odpiranju in zapiranju zagotavlja možnost nastavitve optimalnega tlaka drsnih kolesc vodilnih vozičkov steklenega poklopa na njihove drsne površine znotraj stranskih opor okvira zgornje konstrukcije in pa možnost nastavitve optimalne mase protiuteži glede na maso samega steklenega poklopa. Vsaj v eni od stranskih opor okviija zgornje konstrukcije je lahko nameščen tudi sistem mehkega odpiranja in zapiranja. Običajno zadostuje, da je ta sistem nameščen v eni od stranskih opor zgornje konstrukcije.For conventional manual opening and possible manual closing of the hygienic glass cover for fresh food stalls in accordance with the proposed technical solution, commercially available handles or other grips can be used, which are also used for other simple wings or side movable covers and taps. A smooth and smooth opening and closing movement provides the possibility of setting the optimum pressure of the sliding wheels of the guide rails of the glass cover to their sliding surfaces within the side supports of the frame of the upper structure and the possibility of setting the optimal weight counterweight according to the weight of the glass cover itself. At least in one of the side supports of the frame of the upper structure, a soft opening and closing system can be installed. It is usually sufficient for this system to be installed in one of the lateral supports of the upper structure.
Ključno k lahkotnemu in gladkemu pomiku steklenega poklopa prispeva tudi sama konstrukcija sistema pomika steklenega poklopa, pri kateri se vodilni vozički s svojimi poševno nameščenimi drsnimi kolesci samo dotikajo poševne drsne površine in ne potujejo po polzaprtih profilih ali tirnicah, v katerih lahko potem pri pomikanju steklenega poklopa pride do križanja. Kot nagiba poševnih drsnih površin se pri tem lahko giblje med 100° in 150°. V alternativni izvedbi je lahko sistem pomika steklenega pokopa opremljen z električnim pogonom in senzorjem za prostoročno delovanje za njegovo samodejno odpiranje in zapiranje, kar zagotavlja še privlačnejšo ponudbo jedi, ki so shranjene v pultu za svežo hrano.The key to the smooth and smooth displacement of the glass cover is also provided by the construction of the hinged roofing system itself, where the guide trolleys with their sloping wheel slopes are only touched by the oblique sliding surfaces and do not travel on half-closed profiles or rails in which, when moving the glass cover there is a crossword. As an inclination of oblique sliding surfaces, this can range from 100 ° to 150 °. In an alternative embodiment, the bucket propagation system can be fitted with an electric drive and a hands-free sensor for its automatic opening and closing, which ensures an even more attractive offer of dishes stored in a fresh food counter.
Prednost higienskega steklenega pokrova pultov za svežo hrano skladno s tehnično rešitvijo je tudi dejstvo, da gaje v osnovi mogoče uporabiti za najrazličnejše tipe prodajnih ali samopostrežnih pultov, vključno na primer z obojestransko dostopnimi in tistimi, ki so z eno stranjo prislonjeni k steni. Rešitev je primerna tudi za hladilne pulte na primer za serviranje solat ali pa za ogrevane pulte za serviranje toplih jedi kot tudi za nevtralne pulte. Prednost higienskega steklenega pokrova pultov za svežo hrano skladno s tehnično rešitvijo je poleg že omenjenega lahkotnega in gladkega odpiranja in zapiranja z možnostjo delne ali popolne avtomatizacije le-tega tudi njegov zunanji izgled, ki ga ne kazijo nobeni elementi pomičnega mehanizma, saj so ti v celoti skriti v okvirju zgornje konstrukcije oziroma v stranicah prodajnega pulta.The advantage of the hygienic glass cover for fresh foodstuffs according to the technical solution is also the fact that it can basically be used for a wide variety of types of sales or self-service counters, including for example two-way access and one side facing the wall. The solution is also suitable for refrigerated counters such as salad serving, or for hot serving hotplates as well as for neutral counters. In addition to the aforementioned easy and smooth opening and closing of the hygienic glass cover for fresh foods in accordance with the technical solution, the possibility of partial or complete automation of the latter is also its external appearance, which is not shown by any elements of the movable mechanism, as these are completely hide in the frame of the upper construction or in the sides of the sales counter.

Primer izvedbe tehnične rešitveAn example of a technical solution
Higienski stekleni pokrov pultov za svežo hrano skladno s prikazanim primerom izvedbe, ki je namenjen za obojestransko dostopne hladilne solatne bare, je sestavljen, kot je razvidno s sl. 1, iz navpično pomičnega steklenega poklopal, ki je s pomočjo sistema pomika nameščen v okvir zgornje konstrukcije 2 pulta za svežo hrano nad notranjim prostorom 3 njegove hladilne posode. Okvir zgornje konstrukcije2sestavljata dve stranski opori 2.1 z navpično režo 2.2 na vsaki od njunih nasproti ležečih stranic, pri čemer sta stranski opori 2.1 na zgornji strani med seboj povezani s povezovalno prečko 2.3. Stekleni poklop 1 z zgornje strani tvori sestav med seboj povezanih vrhnjih steklenih plošč 1.1 in stranskih nagnjenih steklenih plošč 1.2, ki so na obeh vzdolžnih stranicah steklenega poklopa 1 opremljene z ročico 1.3, pri čemer je stekleni poklop 1 s strani opremljen s plastičnima stranskima stenama 1.4.The hygienic glass lid for fresh foods according to the embodiment illustrated for use on both sides of the refrigerated salad ponds is composed as shown in FIG. 1, made of vertically movable glass cover, which is positioned in the frame of the upper structure of the 2 table for fresh food above the interior space 3 of its cooling container by means of a shaft system. The frame of the upper structure2 consists of two side supports 2.1 with a vertical slot 2.2 on each of their opposite faces, with the side supports 2.1 on the upper side interconnected by the connecting bar 2.3. The top cover 1 from the upper side forms a set of interconnected glass panes 1.1 and lateral inclined glass panels 1.2 which are provided with a handle 1.3 on both longitudinal sides of the glass cover 1, with the side cover 1 on its side equipped with plastic side walls 1.4 .
Sistem pomika steklenega poklopa 1 je, kot je razvidno iz nadaljnjih slik, vstavljen v okvir zgornje konstrukcije 2 in ga sestavljata dva vodilna vozička 4, 5, od katerih je vsak umeščen v eno od stranskih opor 2.1 in preko navpične reže 2.2 v stranskih oporah 2.1 povezan s priležno stransko steno 1.4 steklenega poklopa 1. Vodilna vozička 4, 5 steklenega poklopa 1 sta na obeh straneh opremljena, kot je razvidno predvsem iz sl. 7 in sl. 8, s pari poševno nameščenih drsnih kolesc 6, ki se z nastavljivim tlakom dotikajo poševnih drsnih površin 7, ki so tvoijene pod kotom 110° znotraj stranskih opor 2.1 okvirja zgornje konstrukcije 2.As shown in the accompanying drawings, the scrolling system of the glass cover 1 is inserted into the frame of the upper structure 2 and consists of two guide trolleys 4, 5 each of which is arranged in one of the lateral support 2.1 and through the vertical slit 2.2 in the lateral supports 2.1 connected to the adjacent side wall 1.4 of the glass cover 1. The guide trolleys 4, 5 of the glass cover 1 are provided on both sides, as shown in particular in FIG. 7 and the like. 8, with pairs of slidly mounted wheels 6 inclined on the sloping wheels 6, which, with adjustable pressure, touch the oblique sliding surfaces 7 which are screwed at an angle of 110 ° inside the side supports 2.1 of the upper structure 2 of the frame.
Nastavitev tlaka obeh vodilnih vozičkov 4, 5 na poševne drsne površine 7 se izvaja s pomočjo nastavljivega vodilnega vozička 4, ki je v ta namen opremljen z dvema nad seboj umeščenima drsnima pušama 10, usmerjenima pravokotno na stransko steno 1.4 steklenega poklopa 1, v katerih sta umeščena navojna drsna vložka 11, ki z enim koncem prehajata skozi stransko steno 1.4 steklenega poklopa 1, na katero sta z njene notranje strani pritrjena s pritrdilnimi vijaki 8, na drugem koncu pa sta drsna vložka 11 opremljena z nastavitvenima vijakoma 12 in prednapetima vzmetema 9.The adjustment of the pressure of the two guiding trolleys 4, 5 to the oblique sliding surfaces 7 is carried out by means of an adjustable guide trolley 4, which is equipped with two above-slip sliding bushings 10, directed perpendicular to the side wall 1.4 of the glass cover 1, in which mounted threaded slide inserts 11 which, with one end, pass through the side wall 1.4 of the glass cover 1 to which are fastened from its inside by fastening screws 8, and on the other end, the slide inserts 11 are provided with adjusting screws 12 and preloaded springs 9.
Drugi vodilni voziček 5 je podobne izvedbe kot prvi vodilni voziček 4 s to razliko, da je namesto drsnih puš 10, kot je razvidno iz sl. 7, opremljen z dvema fiksnima podpornima pušama 13 z notranjim navojem, ki s se s svojima navoj nima koncema dotikata druge stranske stene steklenega poklopa 1, na katero sta z njene druge strani ravno tako pritrjena s pritrdilnimi vijaki8. Na tirnici pomika drugega vozička 5 je v stranski opori 2.1 nameščen mehanizem za mehko odpiranje 23 in mehko zapiranje 24.The second guide trolley 5 is a similar embodiment as the first guide trolley 4, with the difference that instead of sliding sleeves 10, as shown in FIG. 7, provided with two fixed support sleeves 13 with inner thread, which has no ends of the other side wall of the glass cover 1 with which it is attached to the other side by means of fastening screws8. A mechanism for soft opening 23 and a soft closing 24 is mounted in the side support of the second trolley 5 on the track.
Za zagotovitev hkratnega gladkega pomika sta oba vodilna vozička 4, 5 med seboj v gibanju povezana z jeklenim kablom 14, ki poteka po povezovalni prečki 2.3 stranskih opor 2.1 okvirja zgornje konstrukcije 2 od nastavljivega vodilnega vozička 4 preko sestava prenosnih škripcev 15 in s sl. 2 razvidnih protiuteži 16 z nastavljivo maso za optimalno uravnovešenje mase steklenega poklopa 1 do nasproti ležečega vodilnega vozička 5. Oba vodilna vozička 4, 5 sta v ta namen opremljena s pritrdišči za kabel 14 in protiuteži 16, ki niso prikazani na slikah in so tvoijeni iz posameznih jeklenih zank, po potrebi pa jih je mogoče tudi odstraniti ali dodajati.In order to ensure a simultaneous smooth movement, the two guide trolleys 4, 5 are interconnected in motion by a steel cable 14 which extends through the connecting bar 2.3 of the lateral support 2.1 of the upper frame structure 2 from the adjustable guide trolley 4 via the assembly of the transmission pulleys 15 and Fig. 2 illustrative counterweights 16 with adjustable mass for optimum balance of the weight of the glass cover 1 to the opposite guide trolley 5. Both guiding trolleys 4, 5 are equipped with cable anchorages 14 and counterweights 16 which are not shown in the figures and are drawn from individual steel loops and, if necessary, can also be removed or added.
Protiuteži 16 so opremljene z elektromagnetom 17 za vzdrževanje položaja steklenega poklopa 1 v zgornjem položaju po njegovem dvigu, pri čemer je v okvirju zgornje konstrukcije 2 umeščen senzor gibanja 18, ki spremlja prisotnost oseb v prostoru za serviranje jedi in krmili dovod električnega toka v elektromagnet 17. Ko je tok prekinjen, pride do samodejnega spuščanja steklenega poklopa 1 v spodnji položaj, s čimer se prostor nad hladilno posodo zapre. Poleg tega je elektromagnet 17 povezan s prekinitvenim stikalom 19 dovoda električnega toka in opremljen z vzmetnim blažilcem 20 za zagotavljanje možnosti omejenega pomika protiuteži 16 tudi pri prekinjenem električnem toku v elektromagnet 17 v smeri navzgor do položaja, v katerem pride do stika s prekinitvenim stikalom 19, po katerem je mogoče stekleni poklop 1 v spodnji položaj spustiti ročno. V alternativni izvedbi higienskega steklenega pokrova pultov za svežo hrano skladno s to tehnično rešitvijo, ki je shematsko prikazana na sl. 6, je sistem pomika steklenega poklopa 1 opremljen z električnim pogonom 22 in kamemim senzoijem 21 za prostoročno upravljanje njegovega samodejnega odpiranja in zapiranja.The counterweights 16 are equipped with an electromagnet 17 to maintain the position of the glass cover 1 in the upper position after its lift, wherein in the frame of the upper structure 2 there is a motion sensor 18 which monitors the presence of persons in the serving room and controls the supply of the electric current to the electromagnet 17 . When the current is interrupted, the automatic lid of the glass cover 1 will be lowered to the lower position, thereby closing the space above the cooling container. In addition, the electromagnet 17 is connected to the electrical supply circuit breaker 19 and is provided with a spring buffer 20 to provide the possibility of a limited displacement of the counterweight 16 even when the electric current is interrupted in the electromagnet 17 upwards to a position in which a contact is interrupted by a break switch 19, by which the glass cover 1 can be lowered manually in the lower position. In an alternative embodiment of a hygienic glass cover for fresh food desks in accordance with this technical solution, schematically shown in FIG. 6, the sliding system of the glass cover 1 is provided with an electric drive 22 and a camera sensor 21 for the hands-free control of its automatic opening and closing.
Vsa druga električna oprema je v pult za shranjevanje sveže hrane vgrajena pod hladilno posodo, pri čemer je, kot je razvidno iz sl. 1, pult opremljen tudi z odlagalno mizico.All other electrical equipment is installed in a refrigerated storage container in a fresh food storage counter, as shown in FIG. 1, the counter is also equipped with a storage table.
Industrijska uporabljivostIndustrial Usability
Ta tehnična rešitev omogoča široko rabo v velikih trgovskih verigah, nakupovalnih središčih, v hotelih in samopostrežnih bifejih s hrano, uporabiti pa jo je mogoče tudi povsod, kjer je potrebno razstaviti kakršnokoli blago, kot npr. v zlatarnah, vendar v tem primeru je priporočljivo stekleni pokrov opremiti z mehanizmom za zaklepanje.This technical solution enables wide use in large retail chains, shopping centers, hotels and food buffets, and it can also be used wherever goods are to be dismantled, for example, in goldsmiths, but in this case it is advisable to have a glass cover fitted with a locking mechanism.
