Definitions

  • the invention relates to a cartridge press with an actuating housing which has a handle, the movement of which relative to the actuating housing in an actuating direction results in a displacement of a pressure rod displaceably mounted in the actuating housing in a pressure direction, and with a receiving device for receiving a pasty mass which can be pressed out of a hose or a cartridge by the displacement of the pressure rod, wherein the receiving device is rotatably fastened to the actuating housing, for which purpose a fastening base having an opening for the passage of the pressure rod projects into a fastening opening and is there tied axially relative to the pressure rod with a form-fitting fastening means.
  • the invention further relates to a cartridge press with an actuating housing which has a handle, the movement of which relative to the actuating housing in an actuating direction results in a displacement of a pressure rod in a pressure direction, with a receiving device for receiving a pasty mass which can be pressed out of a hose or a cartridge by the displacement of the pressure rod and with a release lever arranged on a first side of the pressure rod on the actuating housing for interacting with a push-back locking element, and with a changeover switch which can be brought from a first switching position, in which the push-back locking element assumes an operative position relative to the pressure rod, into a second switching position, in which the push-back locking element assumes an inoperative position relative to the pressure rod.

  • a torque must be applied to the sleeve section.

  • the cartridge presses shown in the drawings have an actuating housing 1, which is made of plastic or another material, such as metal, and on which a Handle 2 in the direction of a handle 3 is also pivotally connected to a release lever 5.

  • the pivot axis 35 is inserted into an eccentric bushing 34 which is mounted in a bearing cavity of the housing.
  • the eccentric bushing 34 can be rotated by means of a changeover lever 33 attached to the eccentric bushing 34 in order to change the angle that the handle 2 assumes in relation to the handle 3.
  • the handle 2 is essentially a two-armed lever with a long lever arm that can be grasped by the fingers of a user's hand and a short lever arm that engages a driving member 8 consisting of two steel plates.
  • a driving member 8 consisting of two steel plates.
  • the driving member 8 is tilted.
  • the pressure rod 4 passes through an opening in the driving member 8, so that the driving member 8 tilts relative to the pressure rod 4 when tilted.
  • a displacement of the driving member 8 by pivoting the handle 2 thus results in a linear displacement of the pressure rod 4 in the pressure direction, in which the pressure plate 27 is displaced within the receiving device 10 in the direction of a grommet 30.

  • the push-back locking member 9 can be a steel plate that has an opening through which the push rod 4 passes. If the push-back locking member 9 assumes a tilted position relative to the push rod 4, the push rod 4 can only be displaced in the pressure direction. If, however, the push-back locking member 9 does not assume a tilted position, the push rod 4 can be displaced axially in both directions relative to the push-back locking member 9.
  • the actuating housing 1 has a first side on which the release lever 5 and the handle 2 as well as the handle 3 are arranged. A second side is opposite this first side.

  • the changeover switch 6 can be switched from a first switching position, which is in the Fig. 2 shown, can be brought into a second switching position, which is in the Fig. 11 is shown. In the first switching position, the push-back locking member 9 assumes an active position. In this position, the push rod 4 can only be moved against the pressure direction by actuating the release lever 5.
  • the push-back locking member 9 is thereby its side opposite the release lever 5 is held in the axial direction.
  • the eccentric section 31 presses the edge of the push-back locking element 9 against a housing wall of the actuating housing 1.
  • a spring 22 acts on the push-back locking member 9 in such a way that it assumes a tilted position, so that the push rod 4 becomes wedged in the opening of the push-back locking member 9. If the release lever 5 is pivoted, the push-back locking member 9 is brought out of the tilted position against the force of the spring 22.
  • the return locking element 9 is also brought out of the tilted position when the changeover switch 6 is moved from the Fig. 2 shown first switching position to the one in Fig. 11 shown second switching position. Then the push-back locking member 9 acted upon by the spring 22 is supported on a section of the changeover switch 6 and on the release lever 5 in such a way that the push rod 4 can be moved freely through the opening of the push-back locking member 9.
  • the push-back locking member 9 can thus assume two different inoperative positions, in each of which the push-back locking member 9 extends approximately transversely to the direction of extension of the push rod 4. In a first inoperative position, it is pressed against the housing wall by the projection of the changeover switch 6, designated as the eccentric section 31, and by the short arm of the release lever 5 when the latter is actuated. In the second inoperative position, the push-back locking member 9 is spaced from the housing wall 37 and is held in a parallel position to the housing wall 37 by a section of the changeover switch 6 and by the non-actuated release lever 5.

  • the rotation-inhibiting locking connection between the end piece 24 and the receiving body 25 or the head piece 26 and the receiving body 25 is selected such that a lower torque is required to release the head piece 26 from the receiving body 25 than to release the receiving body 25 from the end piece 24.
  • This has the advantage that to remove the head piece, the cartridge press can be held by the handle 3 and only the head piece 26 needs to be rotated. Since the number of interlocking locking means 42, 40 in the area of the head piece 26 is lower than the number of interlocking locking means 40, 41 in the area of the end piece 24, the head piece 26 can be released from the receiving body 25 without the locking connection between the end piece 24 and the receiving body 25 coming loose. In order to release the locking connection between the receiving body 25 and the end piece 24, a higher torque must be applied.
  • the receiving body 25 and/or the end piece 24 and the head piece 26 are made of an elastically deformable material, so that by applying a torque an elastic deformation occurs, during which the locking beads 40, 41 emerge from the locking grooves 42 assigned to them.
