Definitions

the invention relates to a device for permanent positive and play-free connection of a household appliance on a stick.
the invention on a stem connection for attaching garden tools, for example in the form of rakes, cultivators, hoes, weed killers, etc.
So-called spout devices / spout stems are often used as device-stem connections used, in which in a conical insert sleeve of the device the corresponding conical designed stem end is driven, which is fixed under frictional engagement.
temperature and humidity fluctuations often lead to relative a short time to loosen the frictional connection.
additional Fixing elements used that can cause a positive connection. So it is common in punch the appropriate holes in the spout nails into the end of the stem. Also However, loosening cannot be ruled out here if the wood of the handle end changed over time.
a clamping screw In a known handle fastening device, a clamping screw must be loosened or be tightened. When tightening the screw with the required force takes place, a permanent positive connection can be established. It However, it has been found that the screws are often not tightened sufficiently become and loosen up.
the problem is solved by all of the specified in claim 1 Characteristics.
the invention is accordingly based on the knowledge that the known and long-proven handle mounting coupling with relatively simple measures like this can be modified that a permanent stem connection is created.
the invention relates to a device with a permanent positive play-free connection between a tool handle 10 and a garden tool 12, for example, a cultivator.
the stem 10 which is made of wood or can consist of a tube carries at the end of the device a connector 14, which Grips end of the handle and is attached to this.
the garden tool 12 has a Connector, consisting of a sleeve 16 and one of the above Device plug 18, on.
the sleeve-like connector 14 has one Plastic insert 15 on that with a device insertion hole arranged in the stem axis 20 is provided.
the device insertion hole 20 and the device insertion pin 18 have the same polygonal, preferably rectangular, cross-section, so that when inserted a non-rotatable connection is established.
a leaf spring 22 with her front end 24 firmly anchored and this stands with its rear end that as Bolt latch has an offset 26, in the device insertion hole 20 and is transverse to Arm axis biased.
the connecting sleeve 16 of the device has a sleeve extension 28 which in assembled state ( Figures 2 and 3) the front end of the connecting sleeve 14th of the stem.
the base of this sleeve forms an axial stop surface for the End face of the stem or the connecting sleeve 14 and the insert piece 15.
the Device insertion pin 18 has a chamfered control surface 30 and one at the end transverse locking recess 40.
the front end of the connecting sleeve 14 with spring claws 42 be provided, which act on the device insertion pin and a support on Effect muff bottom.
connection once snapped in, should be maintained permanently.
the device inserted into the stem end without damaging the Loosen connecting parts again. This can be useful if one of the parts damaged and the other part is still fully functional, for example if the Stem.
