Definitions

  • the invention relates to a machine base for a machine tool, according to the preambles of claims 1 and 2, in particular for a powered circular table saw, comprising a machine frame which limits at least in a storage position of the machine base a receiving space for protected receiving and supporting the machine tool, and at least three, preferably four support legs which are pivotally mounted on the machine frame.
  • Such machine bases are known from the prior art and basically have the advantage that the machine base frame can be transferred from a storage position to an operating position in which the support legs serve to support the machine frame on a substrate, wherein the support legs in the storage position at least partially within of the limited by the machine frame receiving space are added.
  • the machine base frame with the machine tool in the storage position is comparatively compact, while in the operating position of the machine frame reliable support of the machine tool is achieved.
  • Such a machine undercarriage is known for example from Festool, wherein the support legs can be pivoted in pairs in relation to the machine frame in the receiving space.
  • the paired support legs do not interfere with each other in Figureschwenktem state, the pivot axis of the first Support leg pair arranged with a larger distance in the operating position to the ground than the pivot axis of the second support leg pair.
