Definitions

  • the invention relates to a clamping device comprising a Guide rail, a supported on the guide rail first clamping element with a first of a pressure piece at a first end a clamping spindle and formed in one clamping direction movable clamping surface and with a clamping handle formed on the opposite end of the clamping spindle, with one on the guide rail guided, movable along this and by a first tilting element lockable slide bracket, which is one of the Carried spindle nut, and with a Feed device, which can be supported on the guide rail second tilting element and a swivel stored, with his handle between the guide rail and a feed lever on a clamping handle of the clamping spindle with which the slide bracket relative to the second tilting element is displaceable in the tensioning direction, and a second clamping element supported on the guide rail with a second clamping surface.
  • Such a tensioning device is for example from the US 4,989,847.
  • this tensioning device is cumbersome to use .
  • the first clamping element relative to move to the second clamping element in order to first Attach tensioning device, with the feed lever in the direction the guide rail is to be moved and as a counter bearing for the hand on one opposite the feed lever Projection extending side of the guide rail is provided.
  • the invention is therefore based on the object of a tensioning device to improve the generic type such that these can be attached ergonomically to a workpiece and the workpiece is finally clamped.
  • This task is the beginning of a tensioning device described type according to the invention solved in that the Feed lever with a first pressure element between the second canting element and the slide bracket acts that when operating the feed lever in the direction of the clamping handle the clamping spindle of the slide bracket relative to the second canting element is displaceable in the tensioning direction.
  • the tensioning device After a first start the tensioning device according to the invention then exists the possibility with the already on the clamping handle of the clamping spindle adjacent hand to tighten this further, the Hand can easily release the feed lever and still the clamping handle of the clamping spindle, for example between the palm of the hand, thumb and palm, can hold on, so that with one hand on the one hand the first clamping element is displaceable and then at already attached clamping device through the full clamping force Turning the clamping spindle can be applied without the There is a need to use a second hand and with this first to hold the clamping device on the clamping handle.
  • Possibility of storage provides that the feed lever on the second canting element about a pivot axis is pivotally mounted and that when the feed lever is actuated the first pressure element is movable in the direction of the slide bracket is.

  • the action on the first slide bracket is also can be implemented in a variety of ways. Because of Simplicity has also proven to be relatively cheap, when the first pressure element on one between the guide rail and the clamping spindle, preferably between the swivel axis of the feed lever and the clamping spindle, extending area of the slide bracket acts.

  • a mechanically particularly favorable solution provides that first and the second pressure element in one piece on the feed lever are integrally formed, so that a particularly simple and inexpensive manufacture of the tensioning device according to the invention is possible.
  • first and the second pressure element approximately symmetrical to the pivot axis of the feed lever are arranged so that when moving the feed lever in the direction of the clamping handle and in the direction the guide rail approximately the same feed paths of the Slide bracket are accessible.
  • first and the second pressure element on the between the guide rail and Area of the slide bracket acting and thus the slide bracket is independent of the direction of the pivoting of the feed lever always in Can move the clamping direction.
  • the second pressure element it has proved to be particularly favorable if the second pressure element to one between the pivot axis of the feed lever and the guide rail area of the slide bracket acts because in this case one of the pressure element exerted force acts on the slide bracket with a moment, that does not work against a canting moment.

  • the counter bearing and a place of action of the tilting spring element on the first tilting element have the greatest possible distance from one another, preferably arranged on opposite sides of the guide rail are.
  • the tilt of the first To also create the possibility to move freely of the first clamping element the tilt of the first To solve tilting element, it would be conceivable, for example, to provide the first canting element with an extension, which can be operated manually and when operated the Tilting of the first tilting element can be canceled.
  • a particularly advantageous solution provides that the housing a storage for on the first tilting element has acting and manually operable release element with which, when actuated, the canting of the first canting element can be canceled.
  • This release element is in an advantageous embodiment formed as a slide, which is slidable the housing is stored.
