Definitions

  • the invention relates to a tool in the manner of a pair of pliers or a wrench, with a handpiece and two gripping jaws which can be moved relative to one another between an open position and a closed position and can be clamped in the closed position, for grasping objects.
  • the invention relates to a universal pliers.
  • Tools which can be adapted to a wide variety of uses and can be adjusted to objects of different sizes are known in the form of pliers or wrenches, the gripping jaws of which can be moved relative to one another by suitable mechanisms the gripping positions can be clamped with more or less large clamping forces.
  • Such pliers consist of two two-armed levers of different lever lengths connected to each other via a joint, in which the longer lever arms are designed as operating handles and the shorter lever arms are designed as gripping jaws.
  • pipe wrenches it is also known to design the articulation point of one two-armed lever so that it can be displaced relative to at least the gripping jaw of the other two-armed lever in such a way that the mouth width between the gripping jaws can be adjusted.
  • the clamping forces that can be achieved between the gripping jaws of such pliers are determined by the different lengths of the lever arms as a function of the manual forces that can be applied to the actuating handles by a user.
  • a movable gripping jaw is slidably guided on a handpiece equipped with a fixed gripping jaw, and a spindle connected to the movable gripping jaw, which interacts with a threaded sleeve that is fixed in the longitudinal direction but otherwise rotatable, serves as a means for adjusting.
  • the invention is intended to create a tool which can be used equally as pliers and / or wrenches and can be adapted in a simple manner to the requirements of the respective application and with which it is possible to apply greater clamping forces than precisely known tools of this type in the case of precisely guided gripping jaws.
  • this object is achieved in that a gripping jaw is guided in a longitudinally movable manner in a guide of the handpiece that extends in the direction of the closing and opening movements, and is guided via a handlebar by means of an actuating lever articulated with its end remote from the latter on the handpiece, which forms a closed multi-link chain with the handlebar, the handpiece and the movable gripping jaw accommodated in the guide, can be actuated between the closed and open positions.
  • Characteristic of the invention is therefore the design of the movable gripping jaw and the actuating means for this in the manner of a push crank, the handpiece with the guide for the movable gripping jaw acting as a frame and the actuating lever as a crank pivotable about its articulation point on the handpiece by a predetermined angle are, while the link articulated at one end to the actuating lever and at the other end to the gripping jaw form the coupling of this drive system.
  • the other gripping jaw of the tool is arranged at the end of the guide for the movable gripping jaw that is remote from the articulation point of the actuating lever, and the guide for the movable gripping jaw can advantageously be a straight guide.
  • the actuating lever with the link providing its operative connection with the movable gripping jaw is designed as a toggle lever drive for this gripping jaw, not only the precise guidance and delivery of the movable gripping jaw to the other succeed, but also the application of extraordinarily large clamping forces between the Gripping jaws that cannot be realized with conventional tools of the type specified at the outset.
  • Another advantageous design feature is that the length of the operative connection between the gripping jaw slidably received in the guide of the handpiece and the actuating lever is adjustable, thereby adapting the tool to the respective requirements of the application, in particular adjusting the jaw width between the gripping jaws to enable.
  • the length adjustability of the handlebar can be realized in that it has a telescopic guide which conveys the stepless length adjustment with a locking means.
  • the telescopic guide can consist of a guide bore extending in the longitudinal axis of the handlebar and a guide pin which can be displaced therein and locked in any setting position.
  • An adjustment thread with self-locking can serve as a means for adjusting the length of the handlebar.
  • a simple embodiment results when a threaded spindle and a threaded sleeve cooperating therewith are provided, which are rotatable relative to one another and are each axially fixed to one of the articulation points of the handlebar on the gripping jaw or the actuating lever.
  • the threaded spindle which is axially fixedly connected to the one control arm part, can extend as a guide pin into a longitudinal guide of the other control arm part, in which case the threaded sleeve is axially fixed but rotatably connected to the latter control arm part.
  • Another design feature provides a clamping device acting between the handpiece and the actuating lever for clamping the gripping jaws in the clamping position, which has proven to be particularly advantageous if the tool is to be used, for example, as a wrench.
  • This clamping device can have a clamping thread with self-locking, in the form of a screw bolt that can be clamped between the pivot point of the actuating lever and the handpiece.
  • the arrangement can so that the bolt that can be clamped between the actuating levers and the handpiece is articulated in the vicinity of the guide for the movable gripping jaw on the handpiece and extends through a recess in the actuating lever, a clamping nut acting on the actuating lever being screwed onto the end of the bolt that is remote from the articulation point is.
  • a handpiece 11 In the case of the universal pliers, designated as a whole by 10, a handpiece 11 consists of a grip section 12 and a guide section 13. At the end of the guide section, a fixed gripping jaw 14 is integrally formed on the handpiece. Following this fixed gripping jaw, a guide 15 extends in the guide section 13 in the direction of the grip section 12, which guide can be designed as a dovetail or T-guide and in which a second gripping jaw 16 is accommodated in a longitudinally movable manner. On the side remote from the fixed gripping jaw 14, the guide is blocked by a lock 17 which limits the maximum open position of the movable gripping jaw 16.
  • a Handlebar 18 On the gripping jaw 16 is a Handlebar 18 connected via a pin 19, the other end of which is articulated via a pin 20 to an actuating lever 22.
  • the other end of the actuating lever 22 is articulated via a pin 23 to the end of the handle section 12 remote from the guide section 13.
  • the handpiece 11 with the guide 15 and with the handle section 12, the actuating lever 22 hinged to the latter and the handlebar 18 thus form a closed multi-link chain together with the movable gripping jaw 16.
  • the handlebar 18, which extends between the movable gripping jaw 16 and the end of the actuating lever 22 remote from the grip section 12 of the handpiece 11, is designed to be variable in length and consists of a handlebar part 24 articulated by means of a pin 19 on the movable gripping jaw 16 and one via a pin 20 on the actuating lever 22 articulated handlebar part 25, which has an externally threaded guide pin 26 which is received in a guide bore 27 in the handlebar part 24.
  • this guide hole extends transversely to the latter extending, open to one side, U-shaped transverse recess 28 in the link member 24 into it, in the one with a A ußenriffelung 29 fitted and screwed on the thread of the guide pin 26 of the link member 25 threaded sleeve 30 relative to guide recess 27 is axially fixed in the handlebar part 24, but is rotatably received. It can be seen that by correspondingly turning the threaded sleeve 30 axially fixed on the handlebar part 24 of the guide pin 26 of the handlebar part 25 and thus the latter relative to the one shown in FIGS.
  • an end position can be shifted, which changes the length of the handlebars 18 and so that an adjustment of the jaw width between the gripping jaws 14, 16 results.
  • the cooperating threads of the guide pin 26 and the threaded sleeve 30 are of course designed to be self-locking.
  • the handpiece 111 of the universal pliers 110 likewise consists of a handle section 112 and a guide section 113, at the end of which is remote from the handle section a fixed gripping jaw 114 is arranged.
  • a longitudinal guide 115 extends for the movable gripping jaw 116, the maximum opening position of which is determined by one of the the fixed gripping jaw distal end of the guide 115 arranged lock 117 is limited.
  • the drive movements from the actuating lever 122 which is articulated via a bearing pin 123 at the end of the handle portion 112 remote from the guide portion 113 of the handpiece, are transmitted to the movable gripping jaw 116 via the handlebar 118 consisting of the two length-adjustable handlebar parts 124, 125, the handlebar being connected by means of the pin 119 , 120 is articulated on the movable gripping jaw or the actuating lever.
  • a tensioning device 135 acts between the handle section 112 and the actuating lever 122 and which at the end of the longitudinal guide 115 for the movable gripping jaw 116 by means of a bearing pin 136 on the handpiece articulated threaded pin 137, which extends near the end distant from the handle 112 through a recess 138 of the actuating lever 122 and on the free thread end of which a clamping nut 139 is screwed.
  • the grip section 12, 112 extends from the guide section 13, 113 on the side distant from the gripping jaws 14, 16 and 114, 116 in the manner of a pistol grip, are located at 7 and 8, the handle section 212 and the guide section 213 of the handpiece 211 are approximately in the extended position.
  • the fixed gripping jaw 214 is arranged at the end of the guide section 213 remote from the grip section 212 and the gripping jaw 216 is accommodated in a longitudinally movable manner in the guide delimited by a lock 217. The actuation of the gripper jaw from the open position shown in FIG. 7 into the closed position shown in FIG.
  • a closed multi-link chain is therefore again realized, which in this embodiment, however, has a toggle lever drive for the application of extremely large clamping forces for the gripping jaw 216 movably received in the longitudinal guide 215 forms by means of the length-adjustable handlebar parts 224 and 225 consisting of the handlebar 218 a setting in which the clamping position of the gripping jaws is achieved when the handlebars 218 and the actuating lever are in or approximately in the extended position. This is shown in FIG. 8.
  • return springs can be provided for returning the movable gripping jaw into the open position, which springs are clamped, for example, between the handle section of the handpiece and the actuating lever. For reasons of clarity, however, such return springs have not been shown.
