ELEKTRIČNO IZOLIRANO ROČNO ORODJE Z ZASKOČNIM MEHANIZMOMELECTRICALLY ISOLATED HAND TOOLS WITH LOCKING MECHANISM

Predmet izuma je električno izolirano ročno orodje (“račna”) z zaskočnim mehanizmom, ki dopušča vrtenje, oziroma prenos sile samo v določeni smeri, pri čemer je smer, v katero je možno vrtenje oz. prenos sile, določljiva s pomočjo dveh pritisnih gumbov. Orodje uporabljamo v is kombinaciji z različnimi dimenzijami natičnih nastavkov za privijanje oz. odvijanje matic oz. vijakov z ustrezno oblikovanimi glavami. Izum sodi v razred B 25B 13/46 mednarodne patentne klasifikacije.The subject of the invention is an electrically insulated hand tool ("hand") with a snap mechanism that allows rotation or transfer of force only in a certain direction, the direction in which rotation or rotation is possible. force transfer, determined by two push buttons. The tool is used in combination with various dimensions of the socket mounting screws. unwinding of nuts or. screws with properly shaped heads. The invention belongs to Class B 25B 13/46 of the International Patent Classification.

Tehnični problem, ki ga predložen izum uspešno rešuje je takšna konstrukcija in izvedba električno izoliranega ročnega orodja (“račne”), ki μ bo omogočala učinkovito izolacijo in enostaven preklop smeri vrtenja.A technical problem that the present invention successfully solves is the construction and construction of electrically insulated hand tools ("hand tools"), which will enable effective isolation and easy change of direction of rotation.

Problem izolacije ročnega orodja z zaskočnim mehanizmom (“račne”) je pri dosedanjih konstrukcijah tega orodja rešen s pomočjo plastifikacije običajnega orodja in to posebej ročaja in posebej posameznih natičnih nastavkov. Takšna rešitev je npr. opisana v patentnem dokumentu št. EPThe problem of isolation of a hand tool with a snap mechanism ("handles") has been solved in the structures of this tool so far by the plastification of ordinary tools, and especially of the handle and of the individual sockets. Such a solution is e.g. described in patent document no. EP

Ο 331 534. Pomanjkljivosti takšne rešitve se kažejo predvsem v tem, da takšnega orodja pri kakršnemkoli popravilu ni možno razdreti in popraviti, ampak ga moramo nadomestiti z novim, poleg tega pa je gumb za spremembo smeri vrtenja orodja pri tej rešitvi neizoliran.4. 331 534. The disadvantages of such a solution are mainly due to the fact that such a tool cannot be torn apart and repaired in any repair, but must be replaced with a new one, and the button for changing the direction of rotation of the tool in this solution is uninsulated.

s V patentnem dokumentu EP 0 432 278 je opisano orodje z zaskočnim mehanizmom, pri katerem je omogočen preklop smeri vrtenja s pomočjo drsnega gumba na ročaju. Drsni gumb je povezan z zatikalno kuliso, ki jo premaknemo v eno ali drugo smer in tako omogočimo vrtenje orodja v eno ali drugo smer. Drsno premikajoč gumb v tem primeru ni popolnoma io zanesljiva konstrukcijska rešitev, saj pri slučajnem, nenamenskem pritisku na gumb premaknemo zatikalno kuliso in v primeru močnejše delujoče sile tudi poškodujemo zobnike, ki so trenutno v oprijemu.s EP 0 432 278 discloses a tool with a snap mechanism that enables the rotation direction to be rotated by means of a sliding knob on the handle. The slider is connected to a snap-in scroll, which can be moved one way or the other to allow the tool to rotate in one direction or another. Sliding a button in this case is not a completely reliable construction solution, because by accidentally unintentionally pushing a button, we move the pinion scaffold and, in the case of stronger force, also damage the gears currently in the grip.

Zgoraj opisani izvedbi orodja z zaskočnim mehanizmom rešujeta vsaka zase določen tehnični problem, medtem ko je cilj predložene rešitve is izdelati takšno električno izolirano ročno orodje (“račno”) z zaskočnim mehanizmom, katere konstrukcija bo omogočala zanesljivo električno izolacijo orodja, sistem preklopa smeri vrtenja pa bo enostaven in izvedljiv samo z roko v kateri držimo orodje.The above described implementations of the lathe tool solve each technical problem, while the aim of the proposed solution is to produce such electrically insulated hand tools ("hand") with a lathe mechanism whose construction will allow reliable electrical isolation of the tool and the rotation direction switching system it will only be easy and workable with the hand in which we hold the tool.

Električno izolirano ročno orodje z zaskočnim mehanizmom po izumu ima v osnovi izvedeno telo orodja, ki ga z gornje in spodnje strani zapirata pločevinasta pokrova, nameščen preklopni mehanizem, upravljan z dvema potisnima preklopnima gumboma, ki sta prekrita z mehko opno, celotno orodje prevlečeno z izolacijsko prevleko, ki omogoča dobro električno izoliranost orodja od uporabnika.The electrically isolated hand tool with the locking mechanism according to the invention has a substantially derived tool body, which is closed from the top and bottom by sheet metal lids, a switching mechanism is mounted, operated by two push-button toggles covered with a soft membrane, the entire tool is coated with insulation a cover that provides good electrical insulation of the tool from the user.

Izum bomo podrobneje obrazložili na osnovi izvedbenih primerov in ustreznih slik, od katerih kaže:The invention will be explained in greater detail on the basis of embodiments and corresponding figures, of which:

Električno izolirano ročno orodje z zaskočnim mehanizmom po izumu, is ki je prikazano na slikah od 1 do 3, je v osnovi sestavljeno iz telesa 8 orodja, ki ga z zgornje strani zapira gornji pločevinasti pokrov 5, s spodnje pa spodnji pločevinasti pokrov 6. Oba pokrova 5,6 sta na telo 8 pritrjena z vijakoma 18,19. Na enem koncu orodja sta nameščena gornji ročaj 9 in spodnji ročaj 10, na drugem koncu orodja pa je pravokotno na os telesa 8 nameščen zobnik 1. Skozi zobnik 1 poteka odpiralna os 2, ki deluje preko vzmeti 16 na kroglico 17. S pritiskom na vrh odpiralne osi 2 dosežemo premaknitev osi 2 in tako, da se kroglica 7 umakne v odprtino na osi 2. Na ta način je možna enostavna zamenjava natičnega orodja, medtem ko je pri prvotnem položaju odpiralne osi 2 izpad natičnega orodja zaradi izstopajoče kroglice 17 onemogočen.The electrically insulated hand tool with the locking mechanism according to the invention, shown in Figures 1 to 3, consists essentially of a tool body 8, which is closed from the top by a top canopy 5 and from a lower canopy 6. the covers 5,6 are fixed to the body 8 by screws 18,19. An upper handle 9 and a lower handle 10 are mounted at one end of the tool, and a sprocket 1 is positioned perpendicularly to the axis of the body 8. The opening axis 2 is passed through the gear 1, acting through a spring 16 on the ball 17. By pressing the top of the opening axis 2, the axis 2 is displaced and the ball 7 is withdrawn into the opening on the axle 2. This allows easy replacement of the tool, while the initial position of the opening axis 2 prevents the failure of the tool due to the protruding ball 17.

Približno na sredini orodja po izumu je v telesu 8 nameščen mehanizem za preklop vrtenja v eno ali drugo smer. Sestavljen je iz nihala s 12, preklopnika 13 in vzmeti 14, ki deluje na zatikač 3. Z gornje strani orodja sta nameščena preklopna gumba 11, ki delujeta na nihalo 12. Nihalo 12 v odvisnosti od tega, kateri od preklopnih gumbov 11 je pritisnjen, deluje preko preklopnika 13 na vzmet 14, katere prosti konec omogoča linijski premik zatikača 3, ki ni nikjer vpet in delno leži v io zobniškem oprijemu zobnika 1. Vzdolžni pomik zatikača 3 onemogočata podpori 4. Pri pritisku na enega od obeh preklopnih gumbov 11 se sila prenese na nihalo 12, ki zarotira in premakne preklopnik 13. S tem se spremeni naslon na preklopno vzmet 14 in postavitev zatikača 3 v enega od obeh skrajnih položajev. S pritiskom na drug gumb 11 nihalo is zarotiramo nazaj in preklop se izvrši v nasprotno smer. Zatikač 3 je konstrukcijsko izveden tako, da ga obremenitev zobnika 1 vleče v smer v kateri drži, sila pa se prenese na podporo. Ko zobnik 1 vrtimo v drugo smer se zatikač 3 odmika iz položaja držanja, kar nam omogoči povratni hod. Nazaj v pozicijo držanja ga potiska preklopna vzmet 14. V poziciji držanja ima zatikač 3 v oprijemu več zob, kar omogoča prenašanje tudi večjih momentov.Approximately in the middle of the tool according to the invention, a mechanism is provided in the body 8 for switching rotation in one direction or another. It consists of a pendulum 12, a switch 13, and a spring 14 that acts on the pin 3. On the top of the tool, there are toggle buttons 11 that act on the pendulum 12. The pendulum 12, depending on which of the switch buttons 11 is pressed, acts via a switch 13 on a spring 14, the free end of which allows the linear movement of the pin 3, which is not engaged anywhere and partially rests on the pinion pinion of the pinion 1. The longitudinal movement of the pin 3 prevents the supports 4. By pressing one of the two switching buttons 11, the force it transfers to the pendulum 12, which rotates and moves the switch 13. This changes the backrest to the switch spring 14 and the placement of the pin 3 in one of the two extreme positions. By pressing the other button 11, the pendulum is rotated backwards and the changeover is made in the opposite direction. The pin 3 is constructed so that the load of the pinion 1 pulls it in the direction in which it is held and the force is transferred to the support. When the gear 1 is rotated in the other direction, the pin 3 moves away from the holding position, which enables us to return. It is pushed back into the holding position by the changeover spring 14. In the holding position, the pin 3 has several teeth in the grip, which allows for greater torque transfer.

Oba preklopna gumba 11 sta prekrita z mehko opno 7, celotno telo 8 orodja pa z izolacijsko prevleko 15. Izolacijska prevleka 15 je izvedena z zabrizgavanjem orodja po sami montaži. Sam ročaj orodja je anatomske oblike in je izdelan v kombinaciji z mehkim materialom. Telo 8 je izvedeno iz plastike in ojačano z gornjim pločevinastim pokrovom 5 in spodnjim pločevinastim pokrovom 6.Both toggle buttons 11 are covered with a soft membrane 7 and the entire tool body 8 with an insulating cover 15. The insulating cover 15 is made by injecting the tool after assembly. The tool handle itself is anatomically shaped and is made in combination with a soft material. The body 8 is made of plastic and reinforced with an upper canopy cover 5 and a lower canopy cover 6.
