Opfindelsen angår en fastspændingsindretning af den type, som bruges til midlertidigt at sammenholde to emner, fx ved limning, eller til at fastholde et emne ved svejsning. Der er tale om en hurtigtvirkende fastspændingsindretning, hvor en bevægelig kæbe hurtigt kan rykkes frem, eller hvor den rykkes frem i små trin af valgbar længde. En sådan 5 fastspændingsindretning af stangtypen er velkendt. I de senere år er man gået over til at anvende betjeningshåndgreb, som er drejelige om en tværstift, til brug ved endelig fastgørelse mod emnet, se fx US patent nr. 4.088.313 og US patent nr. 4.563.921. Disse kendte fastspændingsindretninger har den ulempe, at justering af den bevægelige kæbe over en betragtelig afstand er besværlig og upræcis. Ofte frigøres den bevægelige kæbe 10 helt og kan bevæges frit, indtil den endelige fastgørelse af et emne mellem den bevægelige og den faste kæbe opnås. En tredje hånd ville være nyttig.The invention relates to a clamping device of the type used to temporarily compare two items, for example by gluing, or to hold a workpiece by welding. This is a fast-acting clamping device in which a movable jaw can be advanced rapidly or in small steps of selectable length. Such a rod type clamping device is well known. In recent years, operating handles, which are pivotal about a cross-pin, have been used for final attachment to the workpiece, see, for example, U.S. Patent No. 4,088,313 and U.S. Patent No. 4,563,921. These known fasteners have the disadvantage that adjusting the movable jaw over a considerable distance is cumbersome and imprecise. Often, the movable jaw 10 is released completely and can move freely until the final attachment of a workpiece between the movable and fixed jaw is achieved. A third hand would be useful.
Andre fastspændingsindretninger af den omhandlede art er beskrevet i US patentskrift nr. 3.427.016, US patentskrift nr. 4.220.322, GB offentliggørelsesskrift nr. 2 178 689 og DE 15 U1 nr. 87 03 379.Other clamping devices of this type are disclosed in US Patent No. 3,427,016, US Patent No. 4,220,322, GB Publication No. 2 178 689 and DE 15 U1 No. 87 03 379.
Opfindelsen angår en hurtigtvirkende spændeindretning af den ovenfor beskrevne type, der er væsentligt simplere og enklere at betjene end de kendte spændeindretninger.The invention relates to a fast-acting clamping device of the type described above, which is substantially simpler and easier to operate than the known clamping devices.
20 Ved opfindelsen er der således blevet tilvejebragt en hurtigtvirkende spændeindretning omfattende en fast kæbe, en over for den faste kæbe anbragt bevægelig kæbe, en skinne, til hvis ene ende den bevægelige kæbe er fastgjort, og som er bevægelig således, at den bevægelige kæbe kan føres mod og bort fra den faste kæbe, et håndtag, der er udformet på et støtteorgan, og med hvilket spændeindretningen kan holdes, et 25 betjeningshåndgreb, der er monteret på støtteorganet, og envejs drivorganer, der indbefatter en bremsearm, til udløseligt at indgribe med og til, når de er i indgreb, ved betjening af betjeningshåndgrebet at fremføre skinnen og den dertil fastgjorte bevægelige kæbe fra en første stilling til en anden stilling nærmere ved den faste kæbe, idet bremsearmen normalt er i indgreb med skinnen og er indrettet til derved at hindre, at den 30 bevægelige kæbe bevæges i retning bort fra den faste kæbe, medens den bevægelige kæbe kan forskydes i retning mod og bort fra den faste kæbe, når drivorganeme og bremsearmen ved fingerpåvirkning af en betjeningsdel ikke er i indgreb, og spændeindretningen ifølge opfindelsen er ejendommelig ved, at bremsearmens betjeningsdel er anbragt på samme side af håndtaget som betjeningshåndgrebet og er DK 173524 B1 2 indrettet til at blive påvirket med en finger i samme retning, som andre fingre på samme hånd påvirker betjeningshåndgrebet.According to the invention, there has thus been provided a fast-acting clamping device comprising a fixed jaw, a movable jaw placed opposite the fixed jaw, a rail to which one end of the movable jaw is attached and which is movable so that the movable jaw can is moved toward and away from the fixed jaw, a handle formed on a support member with which the clamping device can be held, a control handle mounted on the support member, and one-way drive means including a brake arm for releasably engaging with and, when engaged, by operating the operating handle to advance the rail and the movable jaw attached thereto from a first position to a second position nearer to the fixed jaw, the brake arm normally engaging the rail and being adapted to: prevent the movable jaw from moving in the direction away from the fixed jaw, while the movable jaw may be displaced in the right direction bending against and away from the fixed jaw when the actuating means and the brake arm are not engaged by the actuation of a control part and the clamping device according to the invention is characterized in that the operating part of the brake arm is arranged on the same side of the handle as the operating handle and is arranged to be affected with a finger in the same direction that other fingers on the same hand affect the operating handle.
Fastspændingsindretningen ifølge opfindelsen kan altså betjenes med én og samme 5 hånd. Således kan bremsearmens betjeningsdel bekvemt påvirkes ved hjælp af pege- og langfingeren, og dette vil endvidere sikre, at man ikke ved et uheld kommer til at trykke på betjeningshåndgrebet, fordi håndens modsat rettede kraft virker på bagsiden af spændeindretningens faste håndtag.Thus, the clamping device according to the invention can be operated with one and the same hand. Thus, the operating arm of the brake arm can be conveniently actuated by the forefinger and middle finger, and this will furthermore ensure that you do not accidentally press the operating handle because the opposite directed force of the hand acts on the back of the clamping device fixed handle.
10 Ved en foretrukken udførelsesform er bremsearmen ved sin ene ende svingbart monteret på støtteorganet, og der findes organer til at påvirke bremsearmen i retning af indgreb med skinnen, så at skinnen kan frigøres ved påvirkning af bremsearmens betjeningsdel i retning mod håndtaget. Derved bliver betjeningen af spændeindretningen særlig bekvem.In a preferred embodiment, the brake arm is pivotally mounted at one end to the support member, and means are provided to actuate the brake arm towards engagement with the rail so that the rail can be released by actuating the operating portion of the brake arm toward the handle. This makes the operation of the clamping device particularly convenient.
15 Drivorganeme kan yderligere omfatte en indgrebsarm og påvirkningsorganer til at påvirke indgrebsarmen i retning afen inaktiv stilling, i hvilken den ikke indgriber med skinnen, medens betjeningshåndgrebet kan være indrettet til ved svingning mod håndtaget at tvinge indgrebsarmen i indgreb med skinnen og til at bevæge denne i retning mod den faste kæbe. På denne måde holdes indgrebsarmen ude af indgreb med skinnen, indtil 20 betjeningshåndgrebet påvirkes i retning mod holdehåndtaget.The drive means may further comprise an engaging arm and actuating means for actuating the engaging arm in the direction of an inactive position in which it does not engage with the rail, while the operating handle may be adapted to force the lever into engagement with the rail and to move it in pivot against the handle. direction towards the fixed jaw. In this way the engagement lever is kept out of engagement with the rail until the 20 operating handle is actuated in the direction of the holding handle.

Figur 1-7 viser et hurtigtvirkende fastspaendingsapparat eller en fastspændingsindretning 10 af stangtypen med en bevægelig kæbe 12 forbundet til en giidestang 14. Giidestangen understøttes glidende i en spalte 16 (fig. 4), som går gennem et håndgrebsaggregat 18.Figures 1-7 show a fast-acting clamping device or a rod-type clamping device 10 with a movable jaw 12 connected to a guide rod 14. The guide rod is slidably supported in a slot 16 (Figure 4) passing through a handle assembly 18.
5 Håndgrebsaggregatet 18 omfatter en krop 19, hvor spalten går igennem, et håndtag 20 fastgjort til kroppen 19 på den ene side af spalten 16, og en fast kæbe 22 fastgjort til kroppen 19 på den anden side af spalten 16. Et betjeningshåndgreb 24 er monteret drejeligt på kroppen 19 ved siden af spalten 16 ved hjælp af en drejetap 26. Den bevægelige kæbe 12 er anbragt over for den faste kæbe 22.The handle assembly 18 comprises a body 19 through which the slot passes, a handle 20 attached to the body 19 on one side of the slot 16, and a fixed jaw 22 attached to the body 19 on the other side of the slot 16. An operating handle 24 is mounted. rotatably on the body 19 adjacent to the slot 16 by means of a pivot pin 26. The movable jaw 12 is positioned opposite the fixed jaw 22.

Som det bedst ses på fig. 4, er håndtaget 20 delvis hult således, at det kan optage betjeningshåndgrebet i hulrummet 28. Et andet hulrum 30 i kroppen 19 opdeler boringen 16. En drivarm eller indgrebsarm 32 er ophængt på giidestangen 14, som går gennem et hul 34 i drivarmen 32. En fjeder 36 er sammentrykket mellem drivarmen 32 og overfladen 15 38 af hulrummet 30 og presser dermed drivarmen 32 mod den øvre ende 40 af betjeningshåndgrebet 24. Den øvre ende 40 af betjeningshåndgrebet 24 er forgrenet og skræver over giidestangen 14. Kraften i fjederen 36 presser betjeningshåndgrebet 24 mod en indre overflade 42 af kroppen 19, hvorved der opnås en hviletilstand. I hvilestilstanden er drivarmen 32 anbragt vinkelret på bevægelsesretningen, som vist med pilen 44, for 20 giidestangen 14, når den er i funktion. Enhver bevægelse af håndgrebet 24 omkring omdrejningstappen 26 i retning af pilen 44 sker mod forspændingen af fjederen 36.As best seen in FIG. 4, the handle 20 is partially hollow so that it can receive the operating handle in the cavity 28. Another cavity 30 in the body 19 divides the bore 16. A drive arm or engagement arm 32 is suspended on the guide rod 14 which passes through a hole 34 in the drive arm 32. A spring 36 is compressed between the drive arm 32 and the surface 15 38 of the cavity 30, thereby pushing the drive arm 32 toward the upper end 40 of the operating handle 24. The upper end 40 of the operating handle 24 is branched and extends over the guide rod 14. The force of the spring 36 presses the operating handle. 24 toward an inner surface 42 of the body 19, thereby providing a resting state. In the idle state, the drive arm 32 is perpendicular to the direction of movement, as shown by arrow 44, for the guide rod 14 when in operation. Any movement of the handle 24 around the pivot pin 26 in the direction of the arrow 44 occurs against the bias of the spring 36.
En bremsearm 46 er ophængt fra giidestangen 14, som går gennem en åbning 48 i bremsearmen 46. Den ene ende 50 af bremsearmen 46 er fastholdt drejeligt i en 25 indskæring 52 inden i kroppen 19, således at bremsearmen 46 kan dreje inden for de begrænsninger, der defineres af overfladerne for indskæringen 52, og ved at fastgøre bremsearmen 46 til giidestangen 14, når kanterne for åbningen 48 i armen 46 griber fat i overfladen på giidestangen 14. En fjeder 54 sidder i en indskæring 56 i kroppen 19 og forspændinger den frie ende af bremsearmen 46 bort fra betjeningshåndgrebet 24. Den 30 forspændte stilling for bremsearmen 46 begrænses af berøringen mellem åbningen 48 i armen 46 og giidestangen.A brake arm 46 is suspended from the guide rod 14 which passes through an opening 48 in the brake arm 46. One end 50 of the brake arm 46 is pivotally secured in a cut 52 within the body 19 so that the brake arm 46 can rotate within the constraints. defined by the surfaces of the notch 52, and by attaching the brake arm 46 to the guide rod 14 as the edges of the opening 48 of the arm 46 engage the surface of the guide rod 14. A spring 54 sits in a notch 56 in the body 19 and biases the free end. of the brake arm 46 away from the operating handle 24. The biased position of the brake arm 46 is limited by the contact between the opening 48 of the arm 46 and the guide rod.
Det skal bemærkes, at i den i fig. 4 viste hvilestilling er drivarmen 32 stort set vinkelret på Λ længdeaksen for giidestangen 14, medens den del af bremsearmen 46, som har fat i 35 giidestangen 14, er på tværs af længdeaksen for stangen 24, men ikke vinkelret derpå.It should be noted that in the embodiment shown in FIG. 4, the drive arm 32 is substantially perpendicular to the longitudinal axis of the guide rod 14, while the portion of the brake arm 46 which grips the guide rod 14 is transverse to the longitudinal axis of the rod 24, but not perpendicular thereto.

Hvis en kraft i denne stilling påtrykkes den bevægelige kæbe 12 i retningen, som indikeres med pilen 44, kan giidestangen 14 frit bevæge sig gennem hullet 34 i drivarmen 32 og gennem Ijederen 36. Da bremsearmen 46 frit kan dreje sig mod forspændingen af fjederen 54, nåren kraft påtrykkes den bevægelige kæbe 12 i retning af pilen 44, udgør 5 bremsearmen 46 ikke nogen forhindring for denne bevægelse af giidestangen, og den bevægelige kæbe 12 kan føres kontinuert frem mod den faste kæbe 22.If a force in this position is applied to the movable jaw 12 in the direction indicated by the arrow 44, the guide rod 14 can freely move through the hole 34 in the drive arm 32 and through the spring 36. As the brake arm 46 can freely rotate against the bias of the spring 54, when force is applied to the movable jaw 12 in the direction of arrow 44, the brake arm 46 does not impede this movement of the guide rod and the movable jaw 12 can be advanced continuously towards the fixed jaw 22.
Hvis man imidlertid i hviletilstanden som vist i fig. 4 påtrykker en kraft på den bevægelige kæbe 12 i retningen modsat af retningen vist af pilen 44, vil kanterne af åbningen 48 i 10 armen 46 tage fat mod overfladen på giidestangen 14, og det er ikke muligt uden yderligere indgreb at trække den bevægelige kæbe længere bort fra den faste kæbe 22, som det nærmere vil blive beskrevet i det følgende. Sammentrykningen af fjederen 56 ved at trykke bremsearmen 46 i retning af pilen 44 tillader, at giidestangen 14 og den bevægelige kæbe 12 kan trækkes bort fra den faste kæbe 22. Denne kraft bringer enden 15 50 af armen 46 i vinkelret stilling i forhold til retningen af den påtænkte bevægelse for giidestangen. Giidestangen 14 kan frit glide i begge retninger gennem åbningen 48 i bremsearmen 46.However, if in the resting state as shown in FIG. 4 exerts a force on the movable jaw 12 in the direction opposite to the direction shown by arrow 44, the edges of the aperture 48 in the arm 46 will engage the surface of the guide rod 14 and it is not possible to extend the movable jaw without further engagement. away from the fixed jaw 22, as will be described in more detail below. The compression of the spring 56 by pushing the brake arm 46 in the direction of the arrow 44 allows the guide rod 14 and the movable jaw 12 to be pulled away from the fixed jaw 22. This force puts the end 15 50 of the arm 46 in a perpendicular position with respect to the direction of the the intended movement for the guide rod. The guide rod 14 is free to slide in both directions through the opening 48 of the brake arm 46.
Betjeningshåndgrebet 24 presses i den i pilen 44 viste retning for i små skridt at føre 20 giidestangen 14 med dens tilhørende bevægelige kæbe 12 mod den faste kæbe 22. Betjeningshåndgrebet 24 presses mellem en brugers hånd (ikke vist) og håndtaget 20, sker der en drejning omkring drejetappen 26, og enden 40 af betjeningshåndgrebet 24 bevæger sig i den af pilen 44 viste retning. Dette får drivarmen 32 tit at dreje sig omkring sin øvre ende (fig. 4) således, at drivarmen 32 ikke længere er vinkelret på retningen 44 25 for den tilsigtede bevægelse af giidestangen 14. Drejningen af drivarmen 32 sammentrykker fjederen 36 og får også kanterne af hullet 34 i drivarmen 32 til at trykke sig mod overfladen af giidestangen 14. Fastholdelse sker, fordi drivarmen 32 ikke længere er vinkelret på retningen 44 for den tilsigtede bevægelse for giidestangen 14. Yderligere bevægelse af betjeningshåndgrebet 24 får drivarmen 32 til at forskyde sig i 30 retning af pilene 44. Denne bevægelse sammentrykker yderligere fjederen 36, og denne proces medfører ved hjælp af friktionen mellem armen 32 og stangen 14, at stangen 14 og den dermed forbundne bevægelige kæbe 12 føres frem mod den faste kæbe 22. Det maksimale stykke, som den bevægelige kæbe 12 kan føres frem med et tryk på betjeningshåndgrebet 24, er begrænset, når fjederen 36 er helt sammentrykket eller, i en 35 alternativ konstruktion, håndgrebet 24 rammer den indre overflade 58 af håndtaget 20.The operating handle 24 is pressed in the direction shown in the arrow 44 to guide the guide rod 14 with its associated movable jaw 12 against the fixed jaw in small steps 22. The operating handle 24 is pressed between a user's hand (not shown) and the handle 20, a rotation occurs. about the pivot pin 26 and the end 40 of the operating handle 24 moves in the direction indicated by arrow 44. This causes the drive arm 32 to rotate about its upper end (Fig. 4) so that the drive arm 32 is no longer perpendicular to the direction 44 25 for the intended movement of the guide rod 14. The rotation of the drive arm 32 compresses the spring 36 and also causes the edges of the hole 34 in the drive arm 32 to press against the surface of the guide rod 14. Retention occurs because the drive arm 32 is no longer perpendicular to the direction 44 of the intended movement of the guide rod 14. Further movement of the operating handle 24 causes the drive arm 32 to displace for 30 direction of the arrows 44. This movement further compresses the spring 36, and this process, by means of the friction between the arm 32 and the rod 14, causes the rod 14 and the associated movable jaw 12 to advance toward the fixed jaw 22. The maximum piece which the movable jaw 12 can be advanced by a pressure on the operating handle 24, is limited when the spring 36 is fully compressed or r, in an alternative construction, the handle 24 strikes the inner surface 58 of the handle 20.
DK 173524 B1 5 Håndgrebet 24 kan imidlertid bevæges i enhver mindre bue, hvorved det stykke, som den bevægelige kæbe 12 flytter sig i et enkelt tryk, bliver mindre i forhold til vinklen for betjeningshåndgrebets bevægelse. Yderligere tryk af enhver størrelse på 5 betjeningshåndgrebet 24 kan ske, indtil kæberne 12, 22 når sammen, eller et emne (ikke vist) holdes fast mellem dem.However, the handle 24 can be moved in any smaller arc, whereby the piece on which the movable jaw 12 moves in a single pressure becomes smaller relative to the angle of movement of the operating handle. Additional pressures of any size on the operating handle 24 may occur until the jaws 12, 22 reach together, or a blank (not shown) is held between them.
Når betjeningshåndgrebet 24 er drejet helt i den af pilen 44 viste retning omkring drejetappen 26, medføreren frigørelse af betjeningshåndgrebet 24, at dette håndgreb 24, 10 drivarmen 32 og fjederen 36 vender tilbage til den i fig. 4 viste stilling som et resultat af kræfterne i fjederen 36, som presser komponenterne mod den bevægelige kæbe 12.When the operating handle 24 is turned completely in the direction shown by the arrow 44 around the pivot pin 26, release of the operating handle 24 causes this handle 24, 10 the drive arm 32 and the spring 36 to return to the one shown in FIG. 4 as a result of the forces in the spring 36 pushing the components against the movable jaw 12.
En tværstift 60, som går gennem den frie ende af giidestangen 14, forhindrer, at giidestangen 14 kan trækkes helt ud af spalten 16, når bremsearmen 46 trykkes i retning 15 af pilen 44, og når den bevægelige kæbe 12 manuelt trækkes bort fra den faste kæbe 22.A transverse pin 60 passing through the free end of the guide rod 14 prevents the guide rod 14 from being pulled completely out of the slot 16 when the brake arm 46 is pressed in the direction 15 of the arrow 44 and when the movable jaw 12 is manually pulled away from the fixed jaw 22.
Det skal bemærkes, at betjening af betjeningshåndgrebet 24 ikke kan medføre nogen bevægelse af giidestangen 14 i retning modsat af pilen 44.It should be noted that operating the operating handle 24 may not cause any movement of the guide rod 14 in the direction opposite to the arrow 44.
Blot for illustrationens skyld er der vist beskyttelsespuder 62 fastgjort til kæberne 12, 22.Just for the sake of illustration, protective pads 62 attached to the jaws 12, 22 are shown.
20 Ligeledes for illustrationens skyld er den bevægelige kæbe 12 og håndgrebsaggregatet 18 udformet af halvdele, som holdes sammen af skruer 68.1 den viste udførelsesform (fig.20 For the sake of illustration as well, the movable jaw 12 and the handle assembly 18 are formed of halves held together by screws 68.1 of the embodiment shown (FIG.
4) ifølge opfindelsen har giidestangen 14 et rektangulært tværsnit. I alternative udførelsesformer ifølge opfindelsen kan giidestangen 14 have enhver form, fx kvadratisk, rund, trekantet, og åbningerne 34,48 i armene henholdsvis 32,46 er udformet passende 25 til korrekt friktion med giidestangen 14.4) according to the invention, the guide rod 14 has a rectangular cross section. In alternative embodiments of the invention, the guide rod 14 may have any shape, e.g., square, round, triangular, and the apertures 34,48 in the arms 32,46, respectively, are designed appropriately for proper friction with the guide rod 14.
Det vil altså sige, at hvis vi betragter den situation, hvor et emne skal fastholdes mellem kæberne 12, 22, kan den bevægelige kæbe 12 føres frem mod den faste kæbe 22 enten i én kontinuert bevægelse ved blot at skubbe i den af pilen 44 angivne retning på den 30 bevægelige kæbe 22 eller ved at betjene betjeningshåndgrebet 24 i en serie af tryk, hvis længde bestemmes af brugeren. Store tryk kan benyttes i starten og mindre tryk senere, når det ønskede tryk påføres emnet. Under denne fremføringsoperation forhindrer bremsearmen 46 enhver baglæns bevægelse af giidestangen 14, efter at hvert skridt frem er blevet fuldført. Medens bremsearmen 46 holder stangen 14, frigøres 35 betjeningshåndgrebet 24. Fjederen 36 skubber så håndtaget 24 og drivarmen 32 til de i 6 DK 173524 B1 fig. 4 viste stillinger klar til endnu et tryk. Når som helst brugeren ønsker at trække den bevægelige kæbe 12 bort fra den faste kæbe 22, fx for at frigøre et emne eller for at åbneThat is, if we consider the situation in which a workpiece is to be held between the jaws 12, 22, the movable jaw 12 can be advanced toward the fixed jaw 22 either in one continuous movement simply by pushing in the arrow 44 indicated by direction of the movable jaw 22 or by operating the operating handle 24 in a series of pressures the length of which is determined by the user. Large pressures can be used initially and smaller pressures later when the desired pressure is applied to the workpiece. During this advance operation, the brake arm 46 prevents any backward movement of the guide rod 14 after each step forward has been completed. While the brake arm 46 holds the rod 14, the actuating handle 24. The spring 36 then pushes the handle 24 and the drive arm 32 to those shown in FIG. 4 positions ready for another push. Anytime the user wishes to pull the movable jaw 12 away from the fixed jaw 22, for example, to release a blank or to open
Ti spændeindretningen, for at det kan modtage et emne, er det blot nødvendigt at trække i den bevægelige kæbe 12 i retningen modsat af pilen 44, samtidig med at fjederen 54 5 sammentrykkes ved at trykke på bremsearmen 46 i den af pilen 44 viste retning.For the clamping device to receive a workpiece, it is only necessary to pull the movable jaw 12 in the direction opposite to the arrow 44 while simultaneously compressing the spring 54 by pressing the brake arm 46 in the direction shown by the arrow 44.
Det skal bemærkes at alle betjeningerne af betjeningshåndgrebet 24 og bremsearmen 46 kan udføres med den samme hånd, samtidigt med at denne hånd også holder spændeindretningen 10. Enten pege- eller langfingeren er i position til at påvirke 10 bremsearmen 46 efter behov, medens fingrene omfatter og holder på betjeningshåndgrebet 24 og håndtaget 20.It should be noted that all the controls of the operating handle 24 and the brake arm 46 can be performed with the same hand, while also holding the clamping device 10. Either the forefinger or middle finger is in position to actuate the brake arm 46 as required, while the fingers comprise and holds on the operating handle 24 and the handle 20.
Som det bedst er vist i fig. 2 og 3, er de samlede hurtigtvirkende spændeindretninger 10 ifølge opfindelsen grundlæggende fladt, optager kun lille plads og kan benyttes på snævre 15 steder. Der kan benyttes glidestænger 14 af forskellige længder.As best shown in FIG. 2 and 3, the overall fast-acting clamping devices 10 according to the invention are basically flat, occupy only a small space and can be used in narrow 15 places. Sliding rods 14 of different lengths can be used.
I fig. 1-4 er håndgrebsaggregatet 18 udformet af halvdele, som holdes sammen af skruer 66, og betjeningshåndgrebet 24 er fast og glider ind i hulrummet 28 i håndtaget 20.1 en alternativ udførelsesform (fig. 5-7) omfatter en hurtigtvirkende spændeindretning 110 af 20 stangtypen, et håndgrebsaggregat 118 i ét stykke, som ikke omfatter nogen indvendig indskæring, og et grundlæggende U-formet betjeningshåndgreb 124. Når betjeningshåndgrebet 124 presses mod håndtaget 120, bevæger håndgrebet 124, som det vil fremgå af fig. 7, sig i den af pilen 144 angivne retning og skræver over håndtaget 20. Enden 150 af bremsearmen 146 drejer i en indskæring 152 i 25 håndgrebsaggregatkroppen 119. Betjeningshåndgrebet 124 drejer som om en akse 126 og omfatter halvcirkelformede flanger 170, som strækker sig ind i tilsvarende udformede spalter 172 i kroppen 119.In FIG. 1-4, the handle assembly 18 is formed of halves held together by screws 66, and the operating handle 24 is fixed and slides into the cavity 28 of the handle 20.1. An alternative embodiment (Figs. 5-7) comprises a quick-acting clamping device 110 of the bar type. a one-piece handle assembly 118 which does not include any internal cut-in, and a basic U-shaped operating handle 124. When the operating handle 124 is pressed against the handle 120, the handle 124 moves, as will be seen in FIG. 7, in the direction indicated by arrow 144 and projecting over handle 20. The end 150 of the brake arm 146 rotates in a notch 152 in the handle assembly body 119. The operating handle 124 rotates as an axis 126 and comprises semicircular flanges 170 extending into the correspondingly shaped slots 172 in the body 119.
Funktionen for fastspændingsindretningen ifølge fig. 5-7 er den samme som for den i fig.The function of the clamping device according to FIG. 5-7 are the same as those of FIG.
30 1-4 viste udførelsesform, idet det bemærkes at henvisningsnumrene i fig. 5-7 svarer ti! de numre, som er benyttet ved beskrivelsen af fig. 1-4 blot med 100 lagt til.30 to 4, it is noted that the reference numbers in FIG. 5-7 answers ten! the numbers used in the description of FIG. 1-4 simply with 100 added.
