Pierwszenstwo: 15.11.1971 (P. 151569) Zgloszenie ogloszono: 30.05.1973 Opis patentowy opublikowano: 25.01.1975 74277 KI. 21c,25/03 MKP H05k 5/03 Twórca wynalazku: Czeslaw Nowak Uprawniony z patentu tymczasowego: Zaklady Radiowe „Diora", Dzier¬ zoniów (Polska) Sposób mocowania oslon w obudowach urzadzen Przedmiotem wynalazku jest sposób mocowania oslon w Obudowach urzadzen technicznych zwlasz¬ cza scianek tylnych do skrzynek odbiorników ra¬ diowych. Obudowy i oslony te moga byc wykonane z dowolnych materialów jak drewno, metal, tektu¬ ra, szczególnie zas z tworzyw sztucznych.Znamy sposób oslaniania urzadzen polegal na wy¬ konywaniu w oslonie oraz obudowie otworów, do których wkladano wkrety ii za pomoca nakretek laczono calosc "urzadzania. NieMedy wyuposazano scianki i skrzynki w dodatkowe elementy konstruk¬ cyjne, które umozliwialy polaczenie oslony z obu¬ dowa.Wadami opisanych sposobów mocowania scianek do .skrzynek na przyklad radioodbiorników sa klo¬ potliwe czynnosci w operacji skrecania ze soba oslony i obudowy, które wplywaja na wysoka pra¬ cochlonnosc montazu jak równiez ultrudniaja na¬ prawy sprzetu. Przy stosowaniu specjalnych detali ulatwiajacych pnzyimocowamie scianek wzrastal koszt' produkcji przez naklady na dodatkowe ma¬ terialy i oprzyrzadowamie. I tak w obudowach me¬ talowych wykonywano ksztaltki stalowe, które ostatnio najczesciej zgrzewano z korpiusem, w skrzynkach drewnianych doklejano klockti, a do obudów z tworzyw sztucznych Wprasowywano me¬ taliczne elementy gwintowane lulb wklejano do- daltfcowe wypraski mocujace. Rozwiajzainda takie charakteryzowaly sie niska trwaloscia i mala pewnoscia polaczen zwfesacsa po wJjelokrotriym 2 demontazu. Inna niekorzystna cecha znanyich spo¬ sobów mocowania oslon w skrzynkach sa mozli¬ wosci zagrozenia bezpieczenstwa obslugi w przy¬ padkach wewnetrznych zwarc elektrycznych i prze- 5 dostania sie napiecia na zewnetrzne nieosloniete metaliczne elementy mooujjace.Usuniecie opisanych niedogodnosci byilo celem wynalazczym, które osiagnieto przez opracowanie nowego sposobu mocowanlia scianek do skrzynek io aparatów.Istote wynalazku stanowi sposób (mocowania oslon do obudów urzadzen zwlaszcza radiotech¬ nicznych (polegajacy na wykrojeniu w drewnie kub wyprasowaniu w tworzywie sztucznym odpowied- 15 nich przybrzeznych wyciec w krawedziach skrzyn¬ ki i scianki aipairatu.

Obudowa 1 i oslona 2 wykonane przykladowo z tworzyw 25 sztucznych posiadaja w swych krawedziach wy¬ prasowane przybrzezne rowki 3 i wyciecia 4. Do nich wsuwa sie wkret 5 z nakretka i przez jego dokrecenie laczy sie skrzynke 1 ze scianka 2.Najwazniejsza zaleta sposobu wedlug wynalazku, so który pozwala na latwe zamocowanie do obudów 74 27774 277 3 oslon wyprodukowanych z tworzyw nieprzewo- dzacyoh pradów elektrycznych jest zapewnienie calkowitego bezpieczenstwa dla uzytkowników przez to, ze nie osloniete zewnetrznie imeitaIMczne elementy mocujajce sa wewnatrz urzadzenia po- ikryte warstwa mialterialu izolacyjnego wykluczaja- cego calkowicie mozliwosc pojawienia sie napiecia na izewnajtrz aparatu. Poza tym dodatkowa cecha pozytywna nowego irozwiazania jest uproszczenie i przyspieszenie procesu mocowania oslony zwlasz¬ cza dzieki prostej czynnosci wsuniecia wkretów z nakretkami i podkladkami do odpowiednio przy¬ stosowanych wyciec w skrzynce i sciance. Zastoso¬ wanie itych wyciec pozwolilo wyeliminowac spe¬ cjalne dodatkowe detale konstrukcyjne sluzace dawniej do mocowania oslon wplywajac na oszczed¬ nosci materialowe i obnizke pracochlonnosci wyste- 10 15 pujaca równiez przy wykonywaniu mniej skom¬ plikowanego oprzyrzadowania. Jako dodatkowy walor wynalazku nalezy wymienic jego universal- nosc, bowiem opisany sposób mozna zastosowac do wszelkiego rodzaju obudów jak na przyklad meta¬ licznej, drewnianej i z róznych tworzyw sztucznych, a w kazdym wykonaniu sposób ten zapewnia dobra skutecznosc i dlugotrwala wytrzymalosc oraz este¬ tyczny wyglad zaimorowaniia oslon. PLPriority: November 15, 1971 (P. 151569) Application announced: May 30, 1973 Patent description was published: January 25, 1975 74277 KI. 21c, 25/03 MKP H05k 5/03 Inventor: Czeslaw Nowak Authorized by the provisional patent: Zaklady Radiowe "Diora", Dzierzoniów (Poland) Method of mounting shields in device housings The subject of the invention is the method of mounting shields in housings of technical devices, especially Back panels for radio receiver boxes. These housings and covers can be made of any materials such as wood, metal, cardboard, especially plastic. We know the method of shielding devices by making holes in the cover and housing, to which screws were inserted and the whole device was connected with the help of nuts. However, the walls and boxes were equipped with additional structural elements that made it possible to connect the shield with the housing. The disadvantages of the described methods of attaching walls to boxes, for example radios, are the disruptive activities in the operation of screwing the shield and housing together, which affect the high easy to install as well as make the repair of the equipment very difficult. When special details were used to facilitate the endless strength of the walls, the production cost increased due to the expenditure on additional materials and equipment. Thus, steel shapes were made in metal housings, which were recently most often welded to the body, blocks were glued into wooden boxes, and metal threaded elements or bits were pressed into plastic housings. Such solutions were characterized by a low durability and a low reliability of the connections withfesacs after the dismantling. Another disadvantage of the known methods of fixing the covers in the boxes is the possibility of compromising the safety of operation in the event of internal short circuits and the transfer of voltage to the external bare metallic elements. A new method of attaching walls to boxes and apparatuses. The essence of the invention is a method (attaching covers to casings of especially radio-engineering devices (consisting in cutting out in wood and pressing in plastic appropriate coastal leaks in the edges of the box and aipairat wall. These cut-outs are slipped in and the covers are attached to the housing. The method according to the invention explains the example of fixing the rear wall to the radio box shown in the attached drawing, Fig. 1 of which shows a fragment of the wall box and 2 of them are cross section at the connection point The bottom 1 and the cover 2, for example made of plastics, have in their edges pressed coastal grooves 3 and cuts 4. A screw 5 with a nut is inserted into them and the box 1 is connected to the wall by tightening it. 2. The most important advantage of the method according to the invention , which allows easy attachment to the housings 74 27 774 277 3 shields made of non-conductive plastics is to ensure complete safety for users due to the fact that the external and improper fasteners are inside the device covered with a layer of insulating material excluding there is a possibility of voltage inside and outside the camera. In addition, an additional positive feature of the new solution is the simplification and acceleration of the shield fastening process, especially due to the simple operation of inserting screws with nuts and washers to the appropriately applied cutouts in the box and the wall. The use of these cutouts allowed for the elimination of special additional constructional details formerly used to fasten the covers, affecting material savings and a reduction in labor consumption also occurring in the implementation of less complex equipment. As an additional advantage of the invention, its universality should be mentioned, because the described method can be applied to all kinds of housings, such as metal, wooden and various plastics, and in each embodiment this method ensures good efficiency and long-lasting durability and aesthetic appearance of the imitation. cover.
