Tehnički problemTechnical problem

Tehnički problem koji treba da se reši pronalaskom sastoji se u sledečem: kako ostvariti čvršče povezivanje čivije mehanizma za prikopčavanje na osnovnu ploču uz povečani broj tabaka koji se navlači na čivije, a za istu veličinu mehanizma za prikopčavanje?The technical problem to be solved by the invention consists in the following: how to achieve a more rigid connection of the hinged attachment mechanism to the baseplate with the increased number of hinged attachments for the same size of the attachment mechanism?

Stanje tehnikeThe state of the art

Kod poznatih mehanizama za prikopčavanje, koji se npr. koriste u registratorima, čivije su izvedene sa oblikovanim ogrlicama, koje leže na ravnom, prema gore izvučenom delu osnovne ploče. Kako je prečnik ogrlica veči od prečnika uobičajenih perforiranih otvora, perforirani tabaci leže na ogrlicama, umesto na osnovnoj ploči, čiine se smanjuje broj tabaka koji se navlači na čivije.With known coupling mechanisms, e.g. used in binders, the chihuahuas are made with shaped necklaces, which lie on a flat, upwardly drawn part of the baseplate. As the diameter of the necklaces is larger than the diameter of the usual perforated openings, the perforated tabs lie on the necklaces instead of the base plate, thus reducing the number of tabs that fold into the nibs.

Kod još jednog poznatog mehanizma za prikopčavanje, osnovna ploča ima cilindrični otvor za sprovodjenje jednog kraja čivije, pri čemu osnovna ploča leži uklještena izmedju dva cilindrična dela. Spoljni cilindrični deo zahvata u jedno udubljenje na osnovnoj ploči i zatvara se čvrsto sa gornjom stranem osnovne ploče. Medjutim, kod ovog oblika izvodjenja nije postignuto solidno učvrščivanje čivije u odnosu na osnovnu ploču, tako da se isti lako mogu zakrenuti u odnosu na osnovnu ploču i ne mogu se dovesti više u ispravan položaj.In yet another known attachment mechanism, the base plate has a cylindrical opening for conduction of one end of the nib, with the base plate lying wedged between two cylindrical portions. The outer cylindrical part engages one recess in the baseplate and closes tightly with the upper side of the baseplate. However, in this embodiment, no solid fixture is achieved with respect to the base plate, so that they can easily be rotated with respect to the base plate and can no longer be brought into the correct position.

Opis rešenja tehničkog problemaDescription of solution to a technical problem

Tehnički problem rešen je pronalaskom na taj način, što su u osnovnu ploču, oko oba njena otvora utisnuta konusna udubljenja i u njima zakovane sa konusnom ogrlicom izradjer.e čivije. Na ovaj način biče postignuto, da deo čivije koji se nalazi izvan osnovne ploče, po celoj dužini ima jednak prečnik, tako da se ovaj deo čivije po celoj dužini može koristiti za prihvatanje tabaka, čime se primenom konstrukcije prema pronalasku, može prihvatiti više tabaka, nego što je to slučaj kod poznatih mehanizama. *The technical problem was solved by finding the tapered recesses in the base plate, rounded at both its openings, and riveted in them with a conical collar made more durable. In this way, it will be achieved that the part of the chivia that is outside the base plate has the same diameter throughout the length, so that this part of the chivia along the whole length can be used to receive the plates, which can be used to accept more plates by the construction of the invention. than is the case with known mechanisms. *

Konstrukcija prema pronalasku ne obezbedjuje samo kruče učvrščivanje čivija na osnovnu ploču, več i povečanje breja tabaka koji se postavlja na čivije. Takodje je i utrešak materijala manji kod koriščenja čivija i njihovog učvrščivanja prema pronalasku.The construction according to the invention not only provides a sharper fixation of the chivy to the base plate, but also an increase in the birch of the tabs placed on the chivy. Also, the material shrinkage is less when using chihuahuas and fixing them according to the invention.

Pronalazak če biti bliže objašnjen na osnovu primera izvodjenja prikazanog na ertežima, pri čemu:The invention will be explained in greater detail by way of an exemplary embodiment shown in the drawings, wherein:

Mehanizam za prikopčavanje ima osnevnu pleču 1, na kojoj se nalaze dve čivije 2, koje prema sl. 1 stoje jedna iza druge, i dve kuke 4, medjusobno povezane medjudelom 3. Kuke 4 su cod dejstvom opruge, koja ge pričvrščena na osnovnu ploču 1 i nije prikazana, a zakretne su pemeču poluge 5 koja je uležištena na šapu 6 vezanu za osnovnu pleču 1, a na poiuzi 9 nalazi se valjcie 7 koji pritiska medjudeo 3 tako, da su kuke 4 zakretne izmedju črtasto prikzizancg cc ležaja i položaja prikazar.og punem lir.ijcm. ?ri tem^ su kuke 4 povezane sn osnovnem plocom i, preko savijenih jezičaka 8.The attachment mechanism has a shoulder arm 1, on which there are two nuts 2, which according to FIG. 1 are one behind the other, and two hooks 4 interconnected by the interconnect 3. The hooks 4 are coded by a spring attached to the base plate 1 and not shown, and rotatable by a lever arm 5 which is mounted on the paw 6 attached to the base arm. 1, and at step 9 there is a roller 7 which presses the bear 3 so that the hooks 4 are rotatable between the striped cc bearing and the position shown in full lir. The four tems are hooks 4 connected to the base plate and, via the bent tabs 8.

Sl. 2 i 3 prikazuju csr.cvnu ploču ! u povečane: razmeri, pri čemu- su Šapa 6 i jezicci 8 prikazani ne u konačnem položaju, kac na si. 1, več u medjupoložaju.FIG. 2 and 3 show the csr.cv board! u enlarged: proportions, in which Paw 6 and tabs 8 are not shown in the final position, as in si. 1, more in between.

Osnovna ploča 1 ima dva otvora 9 za pričvrščivanje čivija 2. Iz sl. ¹ prciziazi, da su otvori 9 predvidjer.i u delu 31, kcji J^J u odnosu na rub 10 osnovne ploče 1 povučen nagote, i koji je na mestu otvora 9 utisnut u cilju obrazovanja udubljenja 12, čiji su zidovi deo omotača konusa, pri čemu se prečnik udubljenja 12 smanjuje u pravcu otvora 9. Takodje proizlazi lz sl. 3, da je χ otvor 9 izveden konično, pri čemu prečnik otvora 9 stalno raste u smeru suprotnom udubljenju 12.The base plate 1 has two openings 9 for securing the pin 2. From FIG. ¹ specifies that the openings 9 are predicted in section 31, in which J ^J with respect to the edge 10 of the base plate 1 is drawn inclined, and which is pressed at the location of the opening 9 in order to form recesses 12, the walls of which are part of the cone sheath, wherein the diameter of the recess 12 decreases in the direction of the opening 9. It also follows from FIG. 3, that the χ aperture 9 is conical, with the diameter of the aperture 9 constantly increasing in the opposite direction to the recess 12.

Slika 4 prikazuje čiviju 2, pre učvrščivanja na osnovnu ploču 1. Sa iste slike proizlazi da čivija 2 ima na svom donjem kraju ogrlicu 13, izvedenu iz jedna sa čivijom 2, dok je kraj 14, koji' se nalazi ispod ogrlice, izveden cilindrično, kao i ostali deo čivije 2. Oblik ogrlice 13 odgovara obliku udubljenja 12, a pričvrščivanje čivije 2 na osnevnu ploču 1 vrši se tako, što se čivija 2 svojim krajem 14 postavi u otvor 9 udubljenja 12. Kraj 14 se zakuje, u cilju pričvrščivanja čivije 2 na osnovnu ploču 1. Takodje se vidi, da je konična ogrlica 13 tako postavljena u udubljer.je 12, da čeona površina ogrlice ne viri izvan gornje površine dela 11, osnovne ploče 1.FIG. 4 shows a pin 2, before attaching it to the base plate 1. From the same image, it follows that the pin 2 has at its lower end a collar 13, derived from one with a pin 2, while the end 14, which is' below the collar, is cylindrical. like the rest of the chihuahua 2. The shape of the collar 13 corresponds to the shape of the recess 12, and the attachment of the chivia 2 to the pivot plate 1 is made by placing the chivia 2 with its end 14 in the opening 9 of the recess 12. The end 14 is riveted, in order to attach the chivia 2 to the base plate 1. It is also seen that the conical collar 13 is positioned in the recess 12 so that the front surface of the collar does not extend beyond the upper surface of the base plate 1 portion 11.

Iz ovih razloga tabaci, navučeni na čivije 2 pričvrščene na osnovnu ploču 1, mogu ravne da leže na osnovnoj ploči 1, tako da pri isto j višini čivija 2, može da se navuže veči broj tabaka nego kod poznatih konstrukcija, kod kojih sa čivijom 2 izjedna izvedena ogrlica P leži iznad dela .11. Konstrukcija prema pronalasku, daje ovim ne samb veču krutost čivijama, vec je povečan i kapacitet mehanizma.For these reasons, the tabs attached to the chippers 2 attached to the base plate 1 may lie flat on the base plate 1, so that at the same height of the chippers 2, a larger number of tabs can be threaded than in the known constructions, in which with the chippers 2 an even derived necklace P lies above the .11 part. The construction according to the invention gives these not only greater rigidity to the nuts, but also increases the capacity of the mechanism.
