Definitions

  • the invention relates to an actuating device according to the preamble of patent claim 1.
  • An actuating device of the type mentioned is according to the DE 196 45 778 A1 known.
  • This operating device designed as a tensioning device consists of a rotationally fixed connected to a rotatably mounted in a housing shaft actuator (clamping arm), wherein the actuating element is pivotally connected to a shaft connected to the hand lever, wherein the hand lever of a shaft connected to the connecting element and a thereto fastened, elongated handle member is formed.
  • the grip element is firmly connected to the connection element.
  • the attachment element itself can, as the shaft has a square cross-section perpendicular to its major axis direction, be secured in four different positions on the shaft.
  • the invention has the object to improve an actuator of the type mentioned.
  • the flexibility of the connection of the hand lever to the actuator should be improved.
  • the grip element is designed to be fastened at different positions on a front side of the attachment element which is oriented perpendicular to the main axis direction of the shaft.
  • the invention provides that the attachment of the grip element no longer takes place on a circumferential surface of the connection element, but on its (shaft-free) end face.
  • the number of possible attachment points is limited (for example, four pieces, as in the solution according to the DE 60 2004 010 217 T2 ).
  • the connection element on the other hand, even with a small diameter of the connection element, relatively many attachment points for the grip element can be provided, ie the connection of the hand lever to the actuation device can be adapted much more accurately to the actual spatial conditions at the point of use.
  • FIGS. 1, 2 and 4 shown actuating or clamping devices are all in a known manner from a rotationally fixed to a rotatably mounted in a housing 1 shaft 2 associated actuator 3.
  • the shaft 2 has perpendicular to their in FIG. 1 Dashed main axis direction typically a polygonal cross-section.
  • a square cross section which is also known per se, is particularly preferably provided, because, for example, a hexagonal cross section regularly causes higher production costs.
  • the actuating element 3 is designed to be pivotable with a hand lever 4 connected to the shaft 2, the hand lever 4 being formed from a connecting element 5 connected to the shaft 2, preferably arranged at a free end of the shaft 2 and a longitudinally extended grip element 6 attached thereto ,
  • a handle for example, as in FIG. 4 has a spherical shape; just as well, the handle can also be designed as a corresponding plastic or rubber coating. And this in particular when the grip element 6, which is preferred, is designed as a flat bar with a rectangular cross-section.
  • the shaft 2 (as in the solution according to the DE 196 45 778 A1 ) may consist of a hollow shaft and an inner shaft, in which case the actuating element 3 is rotationally connected to the hollow shaft and the connecting element 5 rotationally connected to the inner shaft.
  • the connecting element 5 is preferably disc-shaped, wherein a disc is to be understood as a cylinder whose thickness (possibly by a multiple) is less than its radius.
  • the grip element 6 is fastened to the attachment element 5 with two fastening connections 8 positioned at a distance from one another.
  • the fastening connections 8 are furthermore preferably each formed from a connecting element-side and a handle-element-side fastening element 9, 10, wherein these fastening elements 9, 10 particularly preferably consist for example of corresponding threaded holes and screws or threaded rods and nuts, d.
  • the fastening connection 8 is preferably designed as a screw connection, wherein further preferably on the handle element 6 two through holes for two corresponding fastening elements 9, 10 are provided.
  • connection element 5 more connection element side Fasteners 9 (for example, as mentioned, tapped holes) are arranged.
  • connection element side Fasteners 9 for example, as mentioned, tapped holes
  • FIGS. 2 and 3 not all connecting element-side fastening elements 9 can be seen here, since two of them are covered by the grip element 6 and the corresponding grip element-side fastening elements 10 (for example, as mentioned, screws).
  • a connecting element-side fastening element 9 (in FIG. 2 Covered by handle element-side fastening element 10) is provided as the center of an imaginary circular path with further connection element-side fastening elements 9, wherein the center of the imaginary circular path on one side (in FIG. 2 left) and the other (three) fasteners 9 on an opposite side (in FIG. 2 right) of the connection element 5 are arranged.
  • this solution only the (complete) loosening of a fastener 10 is required to adjust the handle member 6 with respect to the connecting element 5.
  • FIG. 2 Although a total of only three parking positions seems to reveal, taking into account the fact that the connecting element 5 but in four different positions with the square in cross-section shaft 2 is connected, according to the invention actually twelve different positions (four times three!) Are possible for the grip element 6.
