Definitions

  • the invention relates to a toggle lever tensioning device according to the preamble of the main claim.
  • Such a toggle lever tensioning device is known according to US-A-3 792 853 and a principle similar to US- A -3 924 844.
  • the locking lever in the tensioning device according to US-A-3 792 853 is not located directly on the actuating lever, but on a pivotable with respect to this locking member, which enables locking in the relaxed position, the locking member being braced against the actuating lever with a compression spring. Locking the clamping position with the locking lever or the locking member is not possible.
  • the invention has for its object to improve a toggle lever tensioning device of the type mentioned in such a way that not only this locking in the relaxation position but also in the tensioned position can be effected with a just-formed actuating lever and a correspondingly designed locking lever with the simplest possible design.
  • the housing-side end of the locking lever which has the relaxation lock, is used to form a clamping position lock in the form of a clamping jaw, which is supported in a wedge-like manner on a clamping jaw contact surface of the housing in the clamping position.
  • a clamping position lock In the simple design of the locking lever, which requires no special locking element, the housing-side end of the locking lever, which has the relaxation lock, is used to form a clamping position lock in the form of a clamping jaw, which is supported in a wedge-like manner on a clamping jaw contact surface of the housing in the clamping position.
  • the housing behind the clamping jaw contact surface is advantageously provided with a rounding over which the locking end of the locking lever can slide comfortably.
  • the locking lever is advantageously made from a single punched blank formed, which then Abkantverformung is deformed to the locking lever with a U-shaped cross section, between the free legs of the compression spring is fixed at a suitable point.
  • the width dimensioning of the U-shaped cross section of the locking lever in the region of the locking end is chosen so that the legs of the locking lever are flush with the side cheek surfaces of the device housing, the upper edges of the side cheek walls of the housing forming the clamping jaw contact surfaces for the clamping jaws of the locking lever.
  • the toggle lever tensioning device is explained in more detail below with reference to the drawing of an exemplary embodiment.
  • a toggle lever clamping device consists of a housing 6 'pivotally stored on its side cheeks walls 6 tensioner arm 11 and B e-tuschistshebel 1 which is provided with a latchable to the housing 6, spring-loaded locking lever 3.
  • this device such that the at just formed operating lever 1 pannarmgelenkes above the S 2 hinged locking lever is oriented in the same direction 3, as the operating lever 1, that is, in the illustrated embodiment, the operating lever 1 and the catch lever enclose an acute angle.
  • a compression spring 4 is arranged braced above the locking lever joint 14.
  • the locking end 5 of the locking lever 3 is formed thereon in the form of a clamping jaw 7 which is supported in the locking position on the housing 6 in the manner of a wedge.
  • the locking lever is designed as an angle lever and is articulated with its short leg 15 on the actuating lever 1 or on the joint 14.
  • the locking lever consists of a single punched blank which, at least in the area shown in FIG. 1, is deformed into a U-shaped bracket 3 'in cross section. In Fig. 1, this U-shaped cross section is indicated by dashed lines.
  • the locking lever 3 is covered with a handle 9 in a known manner.
  • the free ends of the short leg 15 of the locking lever 3 are, as shown in Fig. 3, bent inwards, so that, as can be seen from Fig. 3, inserted between the two legs of the actuating lever 1 on the joint 14 and articulated there with the Actuating lever 1 can be connected.
  • the compression spring 4 is formed in the illustrated embodiment in the form of a sleeve spring or a so-called pruning shear spring, which is fixed at its ends to pin-shaped holders 8 of the two levers 1, 3. If such pins are used as holders 8, the actuating lever 1 is provided with beads 13 arranged in its legs, between which the holder 8 is simply driven, as shown. The holder 8 is fixed in a suitable manner on the locking lever 3.
  • holders 8 for example in the form of small receptacles, can also be provided without further notice, and it is also possible, if suitable surface areas are present on the levers, as is the case here with the locking lever 3, to form the holders 8 in the form of small dots on which the open. 1 ends or an open end of the compression spring 4 is seated.
  • the housing 6 of the device has two side cheek walls 6 ', on which the actuating lever 1 and the tensioning arm 11 are mounted.
  • the lock 18 of the locking lever 3 is realized in a simple manner in that at the locking end 5, a locking lever locking extension 19 is integrally formed on at least one side, which can sweep past the housing wall 6 'by means of an offset 21 and, as shown, engages behind the actuating lever stop 20 which is usually present on such devices anyway in the most relaxed position.
  • a locking lever locking extension 19 is integrally formed on at least one side, which can sweep past the housing wall 6 'by means of an offset 21 and, as shown, engages behind the actuating lever stop 20 which is usually present on such devices anyway in the most relaxed position.
