Description
459 955 2 Ytterligare kânnetecknande âr att vid lika stor kolvyta âr kolvens grundform- bredd mindre än rundkolvens diameter. Enl- uppfinningen förutses vidare att kolven vid lika kolvytstorlek kan uppvisa valfri breddstorlek. 459 955 2 A further characteristic is that with the same piston surface area, the basic width of the piston is smaller than the diameter of the round piston. According to the invention, it is further envisaged that the piston with the same piston surface size can have any width size.
Genom utförandet enl. uppfinningen erhålles bland annat den fördelen, att den kan användas vid för en cylinder med rund kolv pà grund av trånga utrymmen icke användbara ställen. För rundkolvutföranden alltför kraftigt begränsade och icke användbara eller 1 övrigt helt oanvändbara ställen kan nu emellertid användas på ett ändamålsenligt sätt.Through the design according to The invention has the advantage, among other things, that it can be used in places which are not usable for a cylinder with a round piston due to narrow spaces. However, for round piston designs that are too severely restricted and unusable or otherwise completely unusable, places can now be used in an appropriate manner.
Härvid förefínns den ytterligare fördelen, att den enl. uppfinningen mindre utrymme krävande anordningen kan i förhållande till utförandet med rund kolv ha lika stor kolvyta. Det är emellertid även med fördel möiligt att välja kolvytan större eller mindre än rundkolvytan.There is the further advantage that according to the device requires less space, the device can have the same piston surface in relation to the round piston design. However, it is also advantageously possible to select the piston surface larger or smaller than the round piston surface.
Därutöver är anordningen enl. den föreliggande ansökan på ett fördelaktigt sätt framställbar pà ett material-, vikt-, arbets- och kostnadsbesparande sätt och mera användbar än de kända anordningarna.In addition, the device according to the present application can be advantageously manufactured in a material, weight, labor and cost saving manner and more useful than the known devices.
Ett utföringsexempel pà uppfinningen visas på den bifogade ritningen och beskrivas i det följande. Pà ritningen visar: - fig. 1 en lângssektionsvy av anordningen i spännarmens vilolâge, - fig. 2 en sektion A-B enl. fig. 1 med en grundform hos cylindern och kolven av en lângstrâckt oval, - fig. 3 en cylindrisk kolv med kolvytstorleken "X" och - fig. 4 en kolv med làngstrâckt oval och kolvytstorleken "X".An embodiment of the invention is shown in the accompanying drawing and is described in the following. In the drawing: - Fig. 1 shows a long sectional view of the device in the rest position of the clamping arm, - Fig. 2 a section A-B according to Fig. 1 with a basic shape of the cylinder and the piston of an elongated oval, - Fig. 3 a cylindrical piston with the piston size "X" and - Fig. 4 a piston with an elongated oval and the piston size "X".
I ett ett- eller flerdelat hus 1 har anordnats ett ifråga om sin grundform smalt cylinder- eller arbetsrum 2 med en däri axiellt förskjutbar kolv 3 med motsvarande grundform. Den tillsammans med kolven 3 förskiutbara kolvstàngen 4 âr vid sin utskjutande ände 5 på i och för sig känt sätt försedd med en lânkdel 6 så att kolvens 3 och kolvstàngens 4 rörelser är med eller utan mellandelen 7 överförbara till spânnarmen 8 och denna i motsvarande grad svängbar. I enlighet med de i varje särskilt fall förelig- gande kraven uppvisar cylinder- eller arbetsrummet 2 tillsammans med kolven 3 en làngstrâckt oval. I enlighet med uppfinningen är det möjligt att välja grundformens mätt sådana, att företrädesvis för kolven i utrymmesbe- 'IX 459 955 3 sparande gynnsamt smalt utförande ernàs en lika stor kolvyta "X" som för en ifråga om diametern större utrymme fordrande cylindrisk kolv. Av fig- 3 och 4 framgår tydligt vilka utrymmesbesparingar, som kan ernás vid lika stor kolvyta genom den i enlighet med uppfinningen smala grundformen hos cylinder- eller arbetsrummet och kolven i förhållande till ett utförande med cylindriskt arbetsrum och kolv. Cylinderrummets och den cylindriska kolvens diameter "a" enl. fig. 3 är avsevärt större än bredden "b" hos den flata kolven enl. fig. 4. Kolvens och arbetsrummets màttförhållanden kan eventuellt bestämmas på sådant sätt att det till och med möjliggöres en större eller mindre kolvytstorlek i förhållande till kolvytan hos en cylindrisk kolv. Härigenom erhålles den fördelen att för den erforderliga eller önskvärda kolvytstorleken kan vid behov anordningen framställas och användas i en bredd, men även í olika breddmàtt. Detta är särskilt gynnsamt för att kunna anbringa och använda anordningen även pà mycket begränsade ställen.In a one- or multi-part housing 1, a narrow cylinder or working space 2 has been arranged in terms of its basic shape with a piston 3 of corresponding corresponding shape axially displaceable therein. The piston rod 4, which is displaceable together with the piston 3, is provided at its projecting end 5 in a manner known per se with a link part 6 so that the movements of the piston 3 and the piston rod 4 are transferable to the clamping arm 8 with or without the intermediate part 7. . In accordance with the requirements in each particular case, the cylinder or working space 2 together with the piston 3 has an elongated oval. In accordance with the invention, it is possible to select the basic shape measured such that, preferably for the piston in space-saving favorable narrow design, an equally large piston surface "X" is obtained as for a cylindrical piston requiring a larger diameter in terms of space. Figures 3 and 4 clearly show the space savings which can be achieved with an equally large piston surface through the narrow basic shape of the cylinder or working space and the piston in accordance with the invention in relation to an embodiment with a cylindrical working space and piston. The diameter "a" of the cylinder space and the cylindrical piston acc. Fig. 3 is considerably larger than the width "b" of the flat piston according to Fig. 4. The dimensional conditions of the piston and the working space can optionally be determined in such a way that even a larger or smaller piston surface size in relation to the piston surface of a cylindrical piston is made possible. This has the advantage that, for the required or desired piston surface size, the device can, if necessary, be manufactured and used in a width, but also in different width dimensions. This is particularly favorable for being able to apply and use the device even in very limited places.
Dylika insatsställen kan utgöras av spalter, mellanrum eller andra tränga ställen, där en anordning med i tvärsnitt cirkulärt cylinderrum och kolv över huvud taget icke eller endast med svårighet kan insättas och användas.Such insertion points may consist of gaps, gaps or other narrow points, where a device with a cylindrical circular chamber and piston in cross section can not be inserted and used at all or only with difficulty.
Kolven 3 och kolvstången 4 har allsidigt säkrats mot vridning i cykinderrum- met 2 för att hindra snedställning, vridning eller andra ofördelaktiga besvärligheter.The piston 3 and the piston rod 4 have been versatile secured against rotation in the cylinder compartment 2 to prevent skew, rotation or other disadvantageous difficulties.
Ansökningsföremälet är icke inskränkt till de angivna anvândningsändamálen, utan det ligger även inom uppfínningens ram att använda det för genomförande av andra uppgifter och arbeten.The subject matter of the application is not limited to the stated uses, but it is also within the scope of the invention to use it for carrying out other tasks and work.
