Description

Opis Description

[0001] Predmetni pronalazak se generalno odnosi na reviziono okno, odnosno na sredstvo za inspekciju ili pristup podzemnoj infrastrukturi. Takvo reviziono okno obuhvata fiksni ram ugrađen u kolovoz, poklopac ili zatvarač (ili rešetku) koji je povezan sa ramom pomoću šarke koja omogućava da se poklopac kreće između položaja zatvaranja otvora rama i položaja oslobađanja otvora da bi se radniku omogućio pristup revizionom oknu. [0001] The subject invention generally relates to an inspection shaft, that is, to a means of inspection or access to underground infrastructure. Such a manhole includes a fixed frame built into the roadway, a cover or shutter (or grate) connected to the frame by a hinge that allows the cover to move between the frame opening closed position and the opening open position to allow worker access to the manhole.

[0002] Na poznati način, reza se može povezati sa poklopcem na suprotnom kraju od njegove šarke na ram i omogućava zaključavanje poklopca u njegovom spuštenom položaju na ramu i otključavanje poklopca što dovodi do njegovog položaja za oslobađanje otvora rama. [0002] In a known manner, a latch can be connected to the cover at the opposite end of its hinge on the frame and allows locking the cover in its lowered position on the frame and unlocking the cover leading to its position for releasing the frame opening.

[0003] Kao što je predstavljeno u dokumentu EP 0 856 611, reza može biti u obliku kolenaste ručice koja je okretno postavljena na poklopac i čiji jedan krak sarađuje sa elementom koji formira udarnu stranu zida rama kako bi se izvršilo zaključavanje poklopca na ram, a drugi krak formira ručku za manipulaciju rezom za dovođenje kraka za zaključavanje u njegov otključani položaj i podizanje poklopca u uspravni položaj dalje od otvora rama. [0003] As presented in the document EP 0 856 611, the latch can be in the form of a crank arm which is rotatably placed on the lid and one arm of which cooperates with the element forming the striking side of the frame wall in order to lock the lid to the frame, and the other arm forms a handle for manipulating the latch to bring the locking arm to its unlocked position and lift the lid into an upright position away from the frame opening.

[0004] Podnosilac prijave je utvrdio da iako je ovaj uređaj za zaključavanje poklopca na ram potpuno zadovoljavajući, ipak nije imun na zlonamerni čin. Zaista, krak koja formira ručku za manipulaciju rezom je lako dostupan izvan poklopca i zauzima svoj zaključani položaj na ramu, tako da svaka zlonamerna osoba može lako dovesti rezu u njen otključani položaj poklopca rama. [0004] The applicant has determined that although this device for locking the cover to the frame is completely satisfactory, it is still not immune to a malicious act. Indeed, the arm which forms the handle for manipulating the latch is easily accessible from outside the cover and takes its locked position on the frame, so that any malicious person can easily bring the latch to its unlocked position of the frame cover.

[0005] Da bi se rešio ovaj problem, predložen je u dokumentu FR 3 022 923 sličan poklopac revizionog okna, čiji poklopac se sastoji od prolaznog otvora u koji se može montirati okretna osovina koja se kontroliše ključem i koji ispod poklopca nosi zasun koji pod dejstvom ključa može da zauzme položaj blokiranja kraka brave u svom položaju zaključavanja poklopca na ram ili položaj deblokiranja kraka za zaključavanje omogućavajući rad drugom kraku reze da bi krak za zaključavanje doveo do njegovog položaja otključavanja poklopca rama. Reviziono okno stavljeno na uvid javnosti u ovom dokumentu ima poboljšanu bezbednost putem primene brave s ključem, ali ima taj nedostatak da otvor i ključem pokretana okretna osovina zauzimaju položaj između reze i centralne zone poklopca. Ovo shodno tome ograničava površinu dostupnu za obeležavanje poklopca. U slučaju rešetke, ovo ograničava otvorenu površinu rešetke, ili ako je ima, i površinu za obeležavanje koja se nalazi na rešetki. [0005] In order to solve this problem, a similar inspection window cover is proposed in document FR 3 022 923, the cover of which consists of a through hole in which a key-controlled pivot shaft can be mounted and which carries a latch under the cover which, under the action of the key, can take the position of blocking the lock arm in its position of locking the cover to the frame or the position of unlocking the locking arm allowing the operation of the second arm of the latch to bring the locking arm to its frame cover unlock position. The inspection window disclosed to the public in this document has improved security through the use of a keyed lock, but has the disadvantage that the opening and the key-operated pivot shaft occupy a position between the latch and the central area of the cover. This consequently limits the area available for marking the cover. In the case of a grid, this limits the open area of the grid, or if there is one, and the marking area located on the grid.

[0006] Pored toga, određene primene mogu zahtevati upotrebu revizionog okna čiji je poklopac (ili rešetka) osiguran rezom sa ključem, dok je poklopac za zatvaranje bez ključa dovoljan za druge primene. Dakle, osim da se u komercijalnom asortimanu kreiraju dva različita poklopca prema predviđenim primenama, zona obeležavanja poklopca se smanjuje bez obzira na to da li je on opremljen ključem ili ne. Pored toga, u slučaju poklopca sa velikom površinom za obeležavanje, takva diferencijacija ne omogućava da se izabere da li će se reviziono okno opremiti bravom sa ključem tokom njegove ugradnje ili ne. [0006] In addition, certain applications may require the use of an inspection window whose cover (or grill) is secured with a key lock, while a keyless closing cover is sufficient for other applications. So, in addition to creating two different covers in the commercial range according to the intended applications, the marking area of the cover is reduced regardless of whether it is equipped with a key or not. In addition, in the case of a cover with a large marking area, such differentiation does not allow choosing whether or not to equip the inspection window with a key lock during its installation.

[0007] Pronalazak ima za cilj da reši najmanje jedan od prethodno navedenih nedostataka. [0007] The invention aims to solve at least one of the aforementioned disadvantages.

[0008] U tom cilju, pronalazak se odnosi na reviziono okno koje sadrži fiksni ram, poklopac ili rešetku povezanu za ram pomoću šarke koja omogućava da se poklopac ili rešetka kreće između položaja zatvaranja otvora rama i položaja oslobađanja ovog otvora i rezu povezanu sa poklopcem ili sa rešetkom u položaju nasuprot šarke. Reza uključuje ručku koja se može pomerati u odnosu na navedeni poklopac ili rešetku, između zaključanog položaja u kome imobilizuje poklopac ili rešetku u odnosu na ram u svom položaju zatvaranja otvora, i položaja otključavanja u kome omogućava okretanje poklopca ili rešetke ka njihovom položaju oslobađanja otvora. Ručka je oblikovana za fiksiranje brave ključem, što omogućava blokiranje ručke reze u njenom položaju zaključavanja ili deblokiranje ručke omogućavajući rad ručke reze da bi se ona dovela u njen položaj otključavanja. [0008] To this end, the invention relates to an inspection window that contains a fixed frame, a cover or a grid connected to the frame by means of a hinge that allows the cover or grid to move between the position of closing the opening of the frame and the position of releasing this opening and a latch connected to the cover or to the grid in a position opposite the hinge. The latch includes a handle which is movable relative to said cover or grill, between a locked position in which it immobilizes the cover or grill relative to the frame in its opening closing position, and an unlocking position in which it allows the cover or grill to be rotated to its opening release position. The handle is shaped to engage the lock with a key, thereby allowing the latch handle to be locked in its locked position or to unlock the handle by allowing the latch handle to be operated to bring it to its unlocked position.

[0009] Zahvaljujući posebnoj konfiguraciji ručke reze koja omogućava pričvršćivanje brave sa ključem, površina poklopca ostaje u velikoj meri dostupna za obavljanje obeležavanja, bez obzira da li je reviziono okno konačno opremljeno bravom sa ključem ili ne. [0009] Thanks to the special configuration of the latch handle that allows the attachment of a key lock, the cover surface remains largely accessible for marking, regardless of whether the inspection window is finally equipped with a key lock or not.

[0010] Reza, na primer, može biti u obliku kolenaste ručice zglobno montirane na poklopac ili rešetku i jedan od krakova sarađuje sa elementom koji formira udarnu ploču zida rama kako bi se izvršilo zaključavanje poklopca ili rešetke na ram, a drugi krak čini ručku za manipulisanje rezom i za podizanje poklopca ili rešetke u položaju otključavanja navedenog poklopca ili rešetke. [0010] The latch, for example, can be in the form of a crank handle hingedly mounted on the cover or grid, and one of the arms cooperates with the element forming the impact plate of the frame wall in order to lock the cover or grid to the frame, and the other arm forms a handle for manipulating the latch and for lifting the cover or grid in the position of unlocking said cover or grid.

[0011] U jednom tehničkom rešenju, ručka ima prolazni otvor, kao konfiguraciju za pričvršćivanje brave sa ključem. U ovom slučaju, otvor koji prolazi kroz ručku može se zatvoriti lomljivim poklopcem koji se može ukloniti pomoću alata da bi se oslobodio otvor i omogućio da se u njega ugradi brava sa ključem. [0011] In one technical solution, the handle has a through opening, as a configuration for attaching a lock with a key. In this case, the opening passing through the handle can be closed with a frangible cover that can be removed with a tool to free the opening and allow a keyed lock to be installed in it.

[0012] Zaun se može napraviti od livenog gvožđa. Može se dobiti izlivanjem u kalupu. Oblikovanje reze može se izvesti bez umetka ili jezgra. [0012] Zaun can be made of cast iron. It can be obtained by pouring in a mold. Slot molding can be done without an insert or core.

[0013] Pronalazak se, takođe, odnosi na sklop koji sadrži reviziono okno kako je prethodno definisano i bravu sa ključem uključujući okretnu osovinu koju kontroliše ključ i koji nosi ispod ručke zasun koji može da zauzme pod dejstvom ključa položaj blokiranja ručke u položaju zaključavanja ili položaj deblokiranja ručke koji omogućava manipulisanje ručkom reze da se ona dovede u njen položaj otključavanja. [0013] The invention also relates to an assembly containing an inspection window as previously defined and a lock with a key including a rotating shaft controlled by the key and which carries under the handle a latch that can take under the action of the key the position of blocking the handle in the locking position or the position of unlocking the handle that allows manipulation of the latch handle to bring it to its unlocking position.

[0014] U jednom tehničkom rešenju iz primera, kada je ručka u položaju zaključavanja, zasun u položaju blokiranja mehanički ometa noseću površinu formiranu ispod poklopca ili rešetke tako da imobiliše ručku u odnosu na poklopac ili rešetku. Noseća površina može biti formirana pomoću kućišta za prihvatanje reze formiranog kao integralni deo poklopca ili rešetke u navedenom poklopcu ili u navedenoj rešetki i ispod donje strane navedenog poklopca ili navedene rešetke. [0014] In one technical solution from the example, when the handle is in the locking position, the latch in the blocking position mechanically interferes with the bearing surface formed under the cover or grid so as to immobilize the handle in relation to the cover or grid. The bearing surface may be formed by means of a housing for receiving a latch formed as an integral part of the cover or grid in said cover or in said grid and below the underside of said cover or said grid.

[0015] Takav sklop može da sadrži sredstvo za indeksiranje koje drži bravu sa ključem u stabilnom položaju bilo u položaju blokiranja ručke ili u položaju deblokiranja ručke. [0015] Such an assembly may comprise an indexing means which holds the keyed lock in a stable position in either the handle locking position or the handle unlocking position.

[0016] Sredstva za indeksiranje mogu uključivati: [0016] Indexing means may include:

• izbočinu koja ima udubljenje u obliku krsta, čvrsto povezanu sa rezom ili formiranu integralno sa rezom, i • a protrusion having a cross-shaped indentation firmly connected to the cut or formed integrally with the cut, and

• podlošku koja ima ispupčenje (izbočinu) prilagođeno da zahvati granu udubljenja u obliku krsta i čvrsto je povezana sa bravom sa ključem, • a washer that has a protrusion (protrusion) adapted to engage the branch of the cross-shaped recess and is firmly connected to the lock with a key,

tako da je navedena izbočina zahvaćena u najmanje prvoj grani udubljenja u obliku krsta kada je brava sa ključem u položaju blokiranja ručke i kada deo izbočine zahvaćen u navedenoj prvoj grani u položaju blokiranja ručke je zahvaćen u drugoj grani udubljenja u obliku krsta ortogonalnoj na prvu granu kada je brava sa ključem u položaju deblokiranja ručke. such that said protrusion is engaged in at least a first branch of the cross-shaped recess when the key lock is in the handle locking position and when a portion of the protrusion is engaged in said first branch in the handle locking position is engaged in a second cross-shaped recess branch orthogonal to the first branch when the key lock is in the handle unlocking position.

[0017] Ostale karakteristike i prednosti pronalaska će se pojaviti u opisu u daljem tekstu. [0017] Other features and advantages of the invention will appear in the following description.

[0019] Na slici 1 je prikazano reviziono okno prema jednom tehničkom rešenju pronalaska. [0019] Figure 1 shows a revision pane according to one technical solution of the invention.

[0020] Poklopac revizionog okna 1 je namenjen za ugradnju u kolovoz i obuhvata ram 2 koji, u prikazanom primeru tehničkog rešenja, ima osmougaoni spoljašnji opšti oblik. Reviziono okno 1 dalje obuhvata poklopac 3 povezan sa ramom 2 pomoću šarke 4. Poklopac 3 čini kapak koji omogućava zatvaranje ili otkrivanje otvora 5 rama 2. Alternativno, rešetka se može koristiti za poklapanje otvora 5 dok se dozvoljava, na primer, prolaz vode u navedeni otvor 5. [0020] The cover of the inspection shaft 1 is intended for installation in the roadway and includes the frame 2 which, in the shown example of the technical solution, has an octagonal external general shape. The inspection window 1 further includes a cover 3 connected to the frame 2 by means of a hinge 4. The cover 3 forms a shutter that allows the opening 5 of the frame 2 to be closed or opened. Alternatively, a grill can be used to cover the opening 5 while allowing, for example, the passage of water into said opening 5.

[0021] Konkretno, poklopac 3 može se zaokretati između položaja zatvaranja otvora 5 rama 2 u kome je navedeni poklopac 3 oboren, horizontalno, preko navedenog otvora 5, i položaja oslobađanja ovog otvora 5. Na primer, u svom položaju za oslobađanje poklopac 3 može da formira ugao od približno 110° u odnosu na ram, položaj otvaranja od 90° omogućava demontažu šarke 4 i vađenje poklopaca 3 iz rama 2. [0021] In particular, the cover 3 can be rotated between the closing position of the opening 5 of the frame 2 in which said cover 3 is knocked down, horizontally, over said opening 5, and the release position of this opening 5. For example, in its release position, the cover 3 can form an angle of approximately 110° in relation to the frame, the opening position of 90° allows the dismantling of the hinge 4 and the removal of the covers 3 from the frame 2.

[0022] Na slici 1 poklopac je prikazan u poluotvorenom položaju, između položaja zatvaranja otvora 5 rama 2 i položaja oslobađanja ovog otvora 5. [0022] In Figure 1, the cover is shown in a half-open position, between the closing position of the opening 5 of the frame 2 and the opening position of this opening 5.

[0023] Šarka 4 može biti tipa koji sadrži osovinu 41 koja je integralna sa poklopcem 3 koji može da se naginje u prostoru 42 u spoljašnjoj ušici 22 rama 2. Naravno, druge vrste zglobnih spojeva poklopca 3 i rama 2 mogu se razmatrati i bez udaljavanja od pronalaska. [0023] The hinge 4 can be of the type containing a shaft 41 which is integral with the cover 3 which can be tilted in the space 42 in the outer eye 22 of the frame 2. Of course, other types of hinged connections of the cover 3 and the frame 2 can be considered without departing from the invention.

[0024] U prikazanom primeru, poklopac 3 je generalno kružnog oblika sposobnog za uklapanje u odgovarajući kružni otvor 5 rama 2 u cilju zatvaranja ovog otvora 5. Poklopac 3 je opremljen centrirajućim ušicama 6 omogućavajući dobro usmeravanje i centriranje poklopca 3 u kružni otvor 5 rama 2. U zatvorenom položaju otvora 5 rama 2, poklopac 3 je oslonjen na unutrašnje periferno rebro 21 rama 2 pomoću elastične potpore integralne sa rebrom 21. [0024] In the example shown, the cover 3 is generally circular in shape capable of fitting into the corresponding circular opening 5 of the frame 2 in order to close this opening 5. The cover 3 is equipped with centering lugs 6 enabling a good orientation and centering of the cover 3 in the circular opening 5 of the frame 2. In the closed position of the opening 5 of the frame 2, the cover 3 is supported on the inner peripheral rib 21 of the frame 2 by means of an elastic support integral with rib 21.

[0025] Reviziono okno 1 je, takođe, opremljeno rezom 7 povezanom sa poklopcem 3 nasuprot šarke 4. Dakle, kada poklopac 3 ima kružni oblik, reza 7 je dijametralno suprotna šarki 4. [0025] The inspection window 1 is also equipped with a cut 7 connected to the cover 3 opposite the hinge 4. Thus, when the cover 3 has a circular shape, the cut 7 is diametrically opposite to the hinge 4.

[0026] Reza 7, čije je tehničko rešenje specifično za pronalazak, prikazana na slikama 3 do 5, je u obliku savijene poluge u suštini pod pravim uglom, postavljena da se može okretati na poklopcu 3. [0026] The latch 7, whose technical solution is specific to the invention, shown in figures 3 to 5, is in the form of a bent lever essentially at a right angle, placed so that it can be turned on the cover 3.

[0027] Kolenasta ručica sadrži prvi krak 71 koji na svom kraju sadrži prvu poprečnu šipku 72 koja je oblikovana tako da sarađuje sa elementom koji formira udarnu ploču 23 i izlazi iz zida rama 2 u njegov otvor 5, kako bi se izvršilo zaključavanje poklopca 3 na ramu 2. Posebno, prva poprečna šipka 72 viri sa obe strane prvog kraka 71 i obuhvata gornju stranicu 73 sposobnu da se postavi sa malim zazorom ispod elementa formirajući udarnu ploču 23 da bi se zaključao poklopac 3 na ramu 2. [0027] The crank arm contains a first arm 71 which at its end contains a first transverse rod 72 which is shaped to cooperate with the element forming the impact plate 23 and exits from the wall of the frame 2 into its opening 5, in order to perform the locking of the cover 3 on the frame 2. In particular, the first transverse rod 72 protrudes from both sides of the first arm 71 and includes an upper page 73 able to be placed with a small gap under the element forming impact plate 23 to lock cover 3 on frame 2.

[0028] Kolenasta ručica sadrži drugi krak koji formira ručku 74 za manevrisanje rezom 7. Ručka 74, takođe, omogućava podizanje poklopca 3 kada se ovaj otključa od rama 2. U tu svrhu, ručka 74 može imati kraj koji olakšava pokretanje (tj. naginjanje ili okretanje) i hvatanje. U tu svrhu, drugi krak koji formira ručku 74 može da sadrži drugu poprečnu šipku 75. [0028] The crank arm contains a second arm that forms a handle 74 for maneuvering the cut 7. The handle 74 also enables the cover 3 to be lifted when it is unlocked from the frame 2. For this purpose, the handle 74 may have an end that facilitates movement (ie tilting or turning) and grasping. For this purpose, the second arm forming the handle 74 may comprise a second transverse bar 75.

[0029] Reza 7 u obliku kolenaste ručice obuhvata okretnu osovinu 76 koja se proteže poprečno na dva kraka brave. Okretna osovina 76 čini koleno između navedena dva kraka i dva u suštini cilindrična poprečna umetka koja štrče sa obe strane kolena reze 7. [0029] Latch 7 in the form of a crank handle includes a pivot shaft 76 that extends transversely on the two arms of the lock. The pivot shaft 76 forms a knee between said two arms and two essentially cylindrical transverse inserts projecting from both sides of the latch knee 7.

[0030] Reza 7 je umetnuta i zadržana u kućištu 31 predviđenom u i ispod poklopca 3. [0030] The latch 7 is inserted and retained in the housing 31 provided in and under the cover 3.

[0031] Kućište 31 ima otvorenu stranu koja izlazi na gornju površinu 32 poklopca 3. Otvorena površina kućišta 31 ima suštinski krstast oblik koji odgovara obliku krsta formiranog od drugog kraka koji formira ručku 74 i drugu poprečnu šipku 75 reze 7, tako da je u zaključanom položaju poklopca 3 na ramu 2, ručka 74 smeštena u otvorenu stranu kućišta 31 bez da viri iz ravne gornje površine 32 poklopca 3. Kućište 31 ima dve ušice 33 koje se nalaze jedna naspram druge na razmaknuti način i nalaze se ispod donje stranice 34 poklopca 3. Ove dve ušice 33 služe kao noseća ležišta za dve izbočine okretne osovine 76 reze 7, ili za smeštaj dela, na primer od plastičnog materijala, koji formira ležajni rukavac između okretne osovine 76 i kućišta 31. Kada se reza 7 ubaci u kućište 31 pokloca 3, reza 7 koja formira kolenastu ručicu može da se okreće u ušicama 33 formirajući noseća ležišta između: [0031] The housing 31 has an open side that protrudes on the upper surface 32 of the cover 3. The open surface of the housing 31 has an essentially cruciform shape corresponding to the shape of the cross formed by the second arm forming the handle 74 and the second transverse bar 75 of the latch 7, so that in the locked position of the cover 3 on the frame 2, the handle 74 is placed in the open side of the housing 31 without protruding from the flat upper surface 32 of the cover 3. The housing 31 has two lugs 33 which are located opposite each other in a spaced manner and are located under the lower side 34 of the cover 3. These two lugs 33 serve as supporting beds for the two protrusions of the pivot shaft 76 of the latch 7, or to accommodate a part, for example of plastic material, which forms a bearing sleeve between the pivot shaft 76 and the housing 31. When the latch 7 is inserted into the housing 31 cover 3, cut 7 which forms a crank handle, it can rotate in the lugs 33, forming bearing bearings between:

• zaključanog položaja poklopca 3 na ramu 2, predstavljenog na slikama 6 i 7, u kome drška 74 zauzima položaj približno paralelno gornjoj površini 32 poklopca 3 i prvi krak 71 se proteže nadole u pravcu suštinski okomito na navedenu gornju površinu 32 poklopca 3, sa gornjom stranicom 73 prve poprečne šipke 72 prvog kraka 71 postavljenom ispod i blizu elementa koji formira udarnu ploču 23 rama 2 da spreči podizanje poklopca 3 u odnosu na ram 2 u odsustvu rada reze 7, i • the locked position of the cover 3 on the frame 2, represented in figures 6 and 7, in which the handle 74 occupies a position approximately parallel to the upper surface 32 of the cover 3 and the first arm 71 extends downwards in a direction substantially perpendicular to said upper surface 32 of the cover 3, with the upper side 73 of the first transverse bar 72 of the first arm 71 placed below and close to the element forming the impact plate 23 of the frame 2 to prevent the lifting of the cover 3 in relation to the frame 2 in the absence of operation of the latch 7, i

• otključanog položaja prikazanog na slici 8 u kome se poklopac 3 može nagnuti pomoću ručke 74 u svoj položaj za oslobađanje otvora 5 rama 2. • the unlocked position shown in Figure 8 in which the cover 3 can be tilted by means of the handle 74 into its position to release the opening 5 of the frame 2.

[0032] Prema pronalasku, ručka 74 obuhvata sredstvo 8 konfigurisano da omogući pričvršćivanje brave sa ključem. To znači da 8 može biti oblikovani oslonac koji omogućava čvrsto pričvršćivanje odgovarajuće brave sa ključem. U primeru predstavljenom ovde, sredstva 8 oblikovana za pričvršćivanje brave sa ključem sadrže otvor 81 koji prolazi kroz dršku prekriven lomljivim poklopcem 82. Lomljivi poklopac 82 može biti odvojen upotrebom odgovarajućeg alata umetnutog na nivou otvora 81. Kada se lomljivi poklopac odvoji, otvor 81 se oslobađa i omogućava ugradnju brave sa ključem kroz ručku 74. Lomljivi poklopac 82 može da se učini odvojivim od ostatka drške 74 tankim vezama napravljenim između pomenutog poklopca i zidova otvora 81 drške 74. Tanke veze pucaju pod dejstvom udarca odgovarajućeg alata, a to može biti malo dleto ubačeno u otvor 81 koji leži na lomljivom poklopcu 82 i na koje se vrši nasilna sila, na primer čekićem, tako da šok potpuno odvaja poklopac 82 sa ručke 74. [0032] According to the invention, the handle 74 comprises a means 8 configured to enable the fastening of a lock with a key. This means that 8 can be a shaped support that allows a suitable lock with a key to be firmly attached. In the example presented here, the means 8 shaped for attaching a key lock comprise an opening 81 passing through the handle covered by a frangible cover 82. The frangible cover 82 can be detached using a suitable tool inserted at the level of the opening 81. When the frangible cover is detached, the opening 81 is released and allows the installation of the key lock through the handle 74. The frangible cover 82 can be made detachable from the rest of the handle 74 by thin connections made between said of the cover and the walls of the opening 81 of the handle 74. Thin connections break under the impact of a suitable tool, which can be a small chisel inserted into the opening 81 lying on the fragile cover 82 and subjected to violent force, for example with a hammer, so that the shock completely separates the cover 82 from the handle 74.

[0033] Lomljivi poklopac se može dobiti u jednom komadu sa ručkom 74, na primer tokom izlivanja, poželjno bez jezgra ili umetka reze 7 koja obuhvata ručku 74. Reza 7 koja sadrži ručku 74 može se posebno napraviti od livenog gvožđa. [0033] The frangible cap can be obtained in one piece with the handle 74, for example during casting, preferably without the core or the insert of the latch 7 which includes the handle 74. The latch 7 which includes the handle 74 can be separately made of cast iron.

[0034] Kada otvor 81 prođe kroz otvor nakon odvajanja poklopca 82 od ručke 74, kroz otvor 81 može da se montira brava 9 sa ključem. [0034] When the opening 81 passes through the opening after separating the cover 82 from the handle 74, the lock 9 with the key can be mounted through the opening 81.

[0035] Slika 5, kao i slike 6 do 8, prikazuje rezu 7 čija je ručka 74 opremljena bravom 9 sa ključem. [0035] Figure 5, as well as Figures 6 to 8, shows a latch 7 whose handle 74 is equipped with a lock 9 with a key.

[0036] Brava 9 sa ključem, prilagođena da se montira u otvor 81 prikazan ovde, obuhvata okretnu osovinu 91 koja se kontroliše pomoću ključa, a nije prikazana. [0036] The keyed lock 9, adapted to be mounted in the opening 81 shown here, includes a pivot shaft 91 controlled by a key, not shown.

[0037] Osovina 91 nosi, prema svom kraju koji se pruža ispod drške 74 reze 7, zasun 92. Zasun 92 može da zauzima položaj blokiranja drške 74 reze 7, prikazan na slici 6. Zasun može zauzeti, posle rotacije od oko 90° osovine 91, položaj za deblokiranje ručke 74 reze 7, predstavljen na slici 7. Položaj za deblokiranje drške 74 dozvoljava njen rad, što će reći njenu rotaciju u odnosu na poklopac 3, a samim tim i okretanje reze 7 oko svoje okretne osovine 76. Položaj za deblokiranje ručke 74 stoga omogućava da se reza 7 dovede u nagnuti položaj prikazan na slici 8, u kome je poklopac otključan, što omogućava njegovo otvaranje prema položaju za oslobađanje otvora 5 rama 2. [0037] The shaft 91 carries, towards its end which extends below the handle 74 of the latch 7, a latch 92. The latch 92 can occupy the position of blocking the handle 74 of the latch 7, shown in Figure 6. The latch can occupy, after a rotation of about 90° of the shaft 91, the position for unlocking the handle 74 of the latch 7, presented in Figure 7. The position for unlocking the handle 74 allows it work, that is to say its rotation in relation to the cover 3, and therefore the rotation of the latch 7 around its pivot axis 76. The unlocking position of the handle 74 therefore allows the latch 7 to be brought to the inclined position shown in Figure 8, in which the lid is unlocked, which allows it to be opened towards the release position of the opening 5 of the frame 2.

[0038] Zasun 92 može imati oblik izdužene krute ploče. Zasun 92 je oblikovan da mehanički deluje sa nosećom površinom 35 formiranom ispod poklopca 3 tako da se rad ručke 74 i naginjanje reze 7 sprečava, kada je navedeni zasun u poziciji blokiranja drške koja je prikazana na slici 6. Zasun 92 je spojen sa osovinom 91. Zasun se prostire pod pravim uglom u odnosu na osovinu 91. Rotacijom osovine 91 zasun 92 može da se uvede u položaj deblokiranja ručke 74, kako je prikazano na Sl.7. U položaju deblokiranja drške 74, zasun 92 više ne ometa noseću površinu 35, koja oslobađa rad drške 74 i reze 7. [0038] The latch 92 may have the form of an elongated rigid plate. The latch 92 is designed to mechanically interact with the bearing surface 35 formed under the cover 3 so that the operation of the handle 74 and tilting of the latch 7 is prevented, when said latch is in the handle blocking position shown in Figure 6. The latch 92 is connected to the shaft 91. The latch extends at right angles to the shaft 91. By rotating the shaft 91, the latch 92 can be brought into position unlocking the handle 74, as shown in Fig. 7. In the unblocking position of the handle 74, the latch 92 no longer interferes with the bearing surface 35, which releases the operation of the handle 74 and the latch 7.

[0039] Osovina 91 može biti sastavljena od tela generalno cilindričnog oblika. Zasun se može učiniti nepokretnim u rotaciji u odnosu na osovinu 91 tako što će se obezbediti ravan na osovini 91 i probijanjem zasuna otvorom odgovarajućeg oblika. Zasun je imobilisan na osovini 91 pomoću navrtke 93. [0039] The shaft 91 may be composed of a generally cylindrical body. The latch can be made stationary in rotation relative to the shaft 91 by providing a plane on the shaft 91 and piercing the latch with an appropriately shaped hole. The latch is immobilized on the shaft 91 by means of the nut 93.

[0040] Drugi kraj osovine 91 se nalazi iznad drške 74, odnosno je na nivou njene površine koja je izložena gornjoj površini 32 poklopca 3. Na ovom kraju, osovina 91 je opremljena sa glavom 94. [0040] The other end of the shaft 91 is located above the handle 74, i.e. it is at the level of its surface which is exposed to the upper surface 32 of the cover 3. At this end, the shaft 91 is equipped with a head 94.

[0041] Glava 94 počiva na površini drške 74, na primer u kružnom udubljenju 83 formiranom na dršci 74. Podloške mogu biti postavljene između glave 94 i drške 74, olakšavajući rotaciju glave 94 i samim tim osovine 91, i izbegavajući habanje ručke 74. [0041] The head 94 rests on the surface of the handle 74, for example in a circular recess 83 formed on the handle 74. Washers can be placed between the head 94 and the handle 74, facilitating the rotation of the head 94 and thus the shaft 91, and avoiding wear of the handle 74.

[0042] Glava 94 ima oblik prilagođen da se rotira pomoću ključa odgovarajućeg oblika. Dakle, glava 94 može da ima spoljašnji oblik koji nije okretan (cilindar skraćen ravnom površinom koja je uzdužna, kvadratna, trouglasta, šestougla, itd.) ili da ima udubljenje koje omogućava okretanje glave 94 (šestougaono, kvadratno, trouglasto, krstasto, itd.). [0042] The head 94 has a shape adapted to be rotated by means of a key of suitable shape. Thus, the head 94 can have an external shape that is not rotatable (a cylinder truncated by a flat surface that is longitudinal, square, triangular, hexagonal, etc.) or has a recess that allows the head 94 to rotate (hexagonal, square, triangular, cruciform, etc.).

[0043] Očigledno, u pronalasku se mogu uspešno koristiti i drugi tipovi brave sa ključem koji se aktiviraju ključem složenijeg sastava. [0043] Obviously, other types of keyed locks that are activated by a key of a more complex composition can be successfully used in the invention.

[0044] Zavojna opruga 95 je postavljena na osovinu 91 i umetnuta između zasuna 92 i ručke 74. Opruga se, u nivou drške, nalazi na podloški 96. Zavojna opruga 95 može imati nekoliko funkcija. Opruga može održavati bravu ključa u ispravnom aksijalnom položaju u otvoru 81 ručke 74. Posebno, glava 94 se održava ravno u kružnom udubljenju 83, naspram površine ručke 74. [0044] The coil spring 95 is placed on the shaft 91 and inserted between the latch 92 and the handle 74. The spring, at the level of the handle, is located on the washer 96. The coil spring 95 can have several functions. The spring may maintain the key lock in the correct axial position in the opening 81 of the handle 74. In particular, the head 94 is held flat in the circular recess 83 against the surface of the handle 74.

[0045] Zavojna opruga, takođe, može da upravlja sredstvom za indeksiranje držeći bravu sa ključem u stabilnom položaju bilo u položaju blokiranja ručke ili u položaju deblokiranja ručke. [0045] The coil spring can also actuate the indexing means by holding the keyed lock in a stable position in either the handle locking position or the handle unlocking position.

[0046] Kao što je prethodno objašnjeno, položaj za blokiranje ručke odgovara određenoj orijentaciji zasuna 92, a položaj za deblokiranje ručke odgovara orijentaciji zasuna 92 koja je u suštini ortogonalna u odnosu na orijentaciju u položaju za blokiranje. [0046] As previously explained, the locking position of the handle corresponds to a certain orientation of the latch 92, and the unlocking position of the handle corresponds to an orientation of the latch 92 that is substantially orthogonal to the orientation in the locking position.

[0047] Kako bi se garantovala stabilnost zasuna u jednoj ili drugoj od ovih orijentacija, drška je opremljena, na nivou njene donje strane (suprotne strane nosećoj strani glave 94) sa izbočinom 77 kroz koji prolazi otvor 81. Izbočina 77 ima udubljenje 78 u obliku krsta, odnosno udubljenje koje je formirano na navedenoj izbočini 77. [0047] In order to guarantee the stability of the latch in one or the other of these orientations, the handle is equipped, at the level of its lower side (the side opposite to the bearing side of the head 94) with a projection 77 through which the opening 81 passes. The projection 77 has a depression 78 in the shape of a cross, that is, a depression that is formed on said projection 77.

[0048] Poželjno je da se izbočina može formirati u jednom komadu sa rezom 7, ili biti čvrsto pričvršćena za nju. [0048] Preferably, the protrusion can be formed in one piece with the cut 7, or be firmly attached to it.

[0049] Podloška 96 ima, na svojoj prednjoj strani koja je u kontaktu sa izbočinom pod dejstvom spiralne opruge 95, ispupčenje prilagođeno da zahvati krstasto udubljenje 78. [0049] The washer 96 has, on its front side which is in contact with the projection under the action of the spiral spring 95, a projection adapted to engage the cross recess 78.

[0050] Funkcionalno, ispupčenje može biti u obliku jednostavnog klina, ali da bi se garantovala bolja ravnoteža podloške 95, ispupčenje može biti u obliku dva dijametralno suprotna klina, ili četiri klina raspoređena u krst. Ispupčenje se može proizvesti savijanjem podloške 95. Ispupčenje može biti formirano krstom napravljenim na podloški 95, a da odgovara krstastom udubljenju 78, koje je probijeno u svom centru sa rupom koja dozvoljava prolaz osovine 91. Rupa u podloški 96 može imati ravan koji odgovara ravni na osovini 91 kako bi se podloška 96 imobilizirala u rotaciji u odnosu na osovinu 91. [0050] Functionally, the protrusion can be in the form of a simple wedge, but to guarantee a better balance of the washer 95, the protrusion can be in the form of two diametrically opposite wedges, or four wedges arranged in a cross. The bulge may be produced by bending the washer 95. The bulge may be formed by a cross formed on the washer 95, and corresponding to the cross recess 78, which is bored in its center with a hole to allow the shaft 91 to pass through.

[0051] Prema tome, ispupčenje podloške 96 je zahvaćeno najmanje prvim krakom ukrštene matrice kada je brava sa ključem u položaju blokiranja ručke i zahvaćena je drugim krakom ukrštene matrice koji je suštinski ortogonalan u odnosu na prvi krak, kada je brava sa ključem u položaju za deblokiranje ručke. U slučaju poprečnog ispupčenja, navedeno ispupčenje se istovremeno angažuje u četiri kraka krstastog udubljenja 78, element ispupčenja (na primer ogranak krsta) prolazi iz prve grane krstastog udubljenja do drugog dela krstastog udubljenja između položaja blokiranja ručke ključem i položaja za deblokiranje ručke. [0051] Accordingly, the protrusion of the washer 96 is engaged by at least the first leg of the cross die when the key lock is in the handle locking position and is engaged by the second leg of the cross die substantially orthogonal to the first leg when the key lock is in the handle unlock position. In the case of a transverse protrusion, said protrusion is simultaneously engaged in four arms of the cross recess 78, the protrusion element (for example a branch of the cross) passes from the first branch of the cross recess to the second part of the cross recess between the position of locking the handle with the key and the position of unlocking the handle.

[0052] Drugim rečima, deo ispupčenja koji je zahvaćen u prvoj grani u položaju blokiranja drške je zahvaćen u drugom kraku u položaju za deblokiranje drške. [0052] In other words, the part of the protrusion which is engaged in the first branch in the position of locking the handle is engaged in the second leg in the position of unlocking the handle.

[0053] Tako, otključavanje reze 7 (brava je prvobitno na poziciji blokiranja drške i pod pretpostavkom da glava 94 osovine 91 ima spoljni oblik koji dozvoljava njenu rotaciju), operater predstavlja deo koji formira glavu 94 osovine 91 u komplementarno udubljenje za blokiranje i operativni ključ (nije prikazan) i okreće navedeni ključ u smeru koji omogućava da se osovina 91 i zasun 92 obrnu simultano kroz ograničeni ugao rotacije, na primer, 90° u primeru tehničkih rešenja predstavljenih ovde, tako da zasun 92 više ne ometa mehanički element koji je spojen sa poklopcem 3. [0053] Thus, unlocking the latch 7 (the lock is initially in the locking position of the handle and assuming that the head 94 of the shaft 91 has an external shape that allows its rotation), the operator presents the part that forms the head 94 of the shaft 91 into the complementary recess for the blocking and the operating key (not shown) and turns said key in a direction that allows the shaft 91 and the bolt 92 to turn simultaneously through a limited angle of rotation, on for example, 90° in the example of the technical solutions presented here, so that the latch 92 no longer interferes with the mechanical element that is connected to the cover 3.

[0054] Na ovaj način, operater može zatim uhvatiti drugu šipku 75 operativne ručke 74 da rotira rezu 7 tako da zauzme položaj prikazan na slici 8 i odvoji prvu šipku 72 sa donje strane elementa koji formira udarnu ploču 23. U ovom takozvanom otključanom položaju reze 7, operater može da nagne poklopac 3 iz njegovog zatvorenog položaja gde zatvara otvor 5 rama 2 do njegovog položaja za oslobađanje otvora 5 rama 2. [0054] In this way, the operator can then grasp the second rod 75 of the operating handle 74 to rotate the latch 7 so that it takes the position shown in Figure 8 and detaches the first rod 72 from the underside of the element forming the impact plate 23. In this so-called unlocked position of the latch 7, the operator can tilt the cover 3 from its closed position where it closes the opening 5 of the frame 2 to its position for releasing the opening 5 of the frame 2.

[0055] Kada se želi da se ponovo zatvori ram 2 poklopcem 3, poklopac 3 se naginje oko šarke 4 kako bi se pružio horizontalno iznad otvora 5, a ručka 74 se vraća u horizontalni položaj unutar kućišta 31, čime se pomera reza 7 u zaključani položaj sa slika 7 i 8 u kojem prva šipka 72 sarađuje sa elementom koji formira udarnu ploču 23 da imobiliše poklopac. [0055] When it is desired to close the frame 2 with the cover 3 again, the cover 3 is tilted around the hinge 4 to extend horizontally above the opening 5, and the handle 74 is returned to the horizontal position inside the housing 31, thereby moving the latch 7 to the locked position of figures 7 and 8 in which the first rod 72 cooperates with the element forming the impact plate 23 to immobilize the cover.

[0056] Reviziono okno čija je ručka predviđena za ugradnju odgovarajuće brave sa ključem može se, na primer, isporučiti sa kompletom koji omogućava ugradnju (ili ne, prema potrebama) brave sa ključem. Dakle, takav komplet sadrži navedenu bravu sa ključem i, opciono, alate neophodne za njeno sklapanje. U primeru koji je detaljno opisan gore, alat sadrži bušilicu prilagođenu za uklanjanje poklopca koji zatvara prolazni otvor na ručki. [0056] An inspection window whose handle is designed for the installation of a suitable lock with a key can, for example, be supplied with a kit that allows the installation (or not, according to needs) of a lock with a key. Thus, such a kit contains the specified lock with a key and, optionally, the tools necessary for its assembly. In the example detailed above, the tool includes a drill adapted to remove a cap that closes a through hole in the handle.

[0057] Pronalazak je opisan uz upućivanje na reviziono okno čiji poklopac je generalno kružnog oblika, ali se podrazumeva da se može primeniti na bilo koji drugi oblik poklopca, kao što je pravougaoni poklopac koji odgovara pravougaonom obliku rama ili trouglasti poklopac koji odgovara ostalim susednim trouglastim poklopcima u pravougaonom ramu. Pronalazak se može primeniti na reviziono okno sa rešetkom bilo kog od gore navedenih oblika. [0057] The invention is described with reference to an inspection window whose cover is generally circular in shape, but it is understood that it can be applied to any other cover shape, such as a rectangular cover that fits a rectangular frame or a triangular cover that fits other adjacent triangular covers in a rectangular frame. The invention can be applied to an inspection window with a grid of any of the above-mentioned shapes.
