Definitions

  • the invention relates to a handle for an at least partially striking Tool device such as a hammer drill or chisel hammer, which is preferably used in mining is used.
  • Powerful rotary or chisel hammers with a mass greater than 10 kg, as in Mining operations are typically used for their intended purpose operated on drill supports or drill carriages and are used by one person for implementation portable.
  • the tooling devices are usually rough loads subject and are sometimes also dragged across the floor.
  • the tools point along the mostly long tool shank at least partially an axially extending one Rinsing hole for the passage of liquid detergent and coolant such as water either centrally via the tool holder or via one, the tool shank in the Area of a flush opening sealingly enclosing flush head is introduced.
  • this is a form fit in the tool holder striking hand tool device introduced, limited axially movable tool with locked around a circumferential collar via a swiveling wire bracket, which on the Tool holder is attached.
  • a rotary hammer is also used for dust extraction, hollow side handle airtight with a suction head, which the tool in Seals area of a suction opening.
  • a heavy chisel hammer has a cranked, rotating one Support frame, with the tool-shaped, above the direction of impact the bow-shaped handle arranged on the tool holder does not hold the tool holder protects against direct contact with the ground.
  • the supporting frame surrounding the tool device is very bulky.
  • a wood chisel has a tool holder on the tool holder a side guide handle, which in connection with a handle for Attaching one arm to the user's forearm allows.
  • This guide handle does not protect the tool holder.
  • To the Carrying the wood chisel on the guide handle is anatomically unsuitable.
  • the object of the invention is to realize a multifunctional handle for a heavy tool, which is both for anatomically suitable carrying of the Tool device as well as to protect the tool holder from direct contact with the ground serves.
  • the hand-held at least partially points along the stroke axis striking tool device with a striking mechanism and a tool holder for rotationally positive reception of a tool on a handle, which in Functional unit with a flushing head that can be firmly connected to the tool holder connected is.
  • the handle forms an extension of the tool holder along the stroke axis Emergency skid, over which the tool holder slides in direct contact with the ground and is thus protected from the coarsest impurities.
  • the handle is advantageously formed closed closed, whereby this mechanically very stable and therefore highly resilient.
  • the functional unit consisting of a handle and a flushing head can be easily mounted on the housing of the tool device can be fastened, for example using screws.
  • the handle with both legs in the direction of the tool tip is advantageous cantilevered on the flushing head, whereby the load-bearing point in front of the Tool device relocated, so that long, heavy tools together with the Tool device are portable with one hand.
  • the leg arranged in the direction of the tool tip advantageously forms a bow closed handle a coaxial eyelet through which the tool shank including collar can be inserted coaxially, which means that the handle is symmetrical parallel to Fold axis can be arranged.
  • a locking means for the axially limited is advantageously on the tool side of the handle Movable tool arranged, whereby the locking outside of the Tool holder takes place and thus the rinsing head between the tool holder and the lock can be arranged.
  • a possible empty blow on the tool shank is over the locking device via the handle and the flushing head to the machine housing transferred and thus intercepted.
  • the locking means is advantageous as a tool stop on the handle, Locking flap which can be pivoted axially in the direction of the tool device, which with one edge, facing the tool axis, one radial on the tool shank engages behind the protruding collar and locks the tool shank in this way. Further the locking flap is advantageously resiliently biased, thereby locking done automatically. To unlock the locking flap against the Spring preload swung in on the device side.
  • the flushing head itself advantageously has an inlet opening for the tool device the detergent, which opens into a circumferential groove in which the Tool holder can be inserted coaxially on both sides, and thus an annular space forms, in the axial region of which the radial opening of the tool shank is arranged.
  • the inside of the Tool device directed detergent directly into the rinsing head and from this into the Tool shank and further to the drill head.
  • a tool holder 3 which is an insertion end of the Tool shaft 2 rotatably receives, connected to a flushing head 4, which has a handle-shaped closed handle 5 in the functional unit.
  • the Functional unit consisting of handle 5 and rinsing head 4 can be easily assembled using screws and removably attached to the housing 6 of the tool.
  • the handle 5 is one Flapping axis A with both legs 7a, 7b projecting in the direction of the tool tip on Rinsing head 4 arranged.
  • bracket-shaped handle 5 forms a coaxial eyelet 8 through which the Tool shaft 2 including a radially projecting collar 9 is introduced coaxially.
  • the handle 5 has an axial stop on the tool side Locking flap pivotable in the direction of the tool device as locking means 10 arranged, which is biased with respect to a pivot axis S via a spring 11.
  • the rinsing head itself has an inlet opening 12 oriented toward the tool device 1 for the Detergent, which opens into a circumferential groove 13 into which the tool holder 3 coaxially insertable on both sides by seals 14a, 14b, which in turn the tool shaft 2 with the radial opening into one within an annular space Detergent channel sealed on both sides.
