Definitions

  • the invention relates to a device for dressing steps made of natural and / or stone with undercut holes designed as blind holes, in particular for producing the undercuts in these holes for receiving connecting elements on stairs, the steps without cheeks and risers connected by bolts are.
  • anchor sleeves with an internal thread are glued into the bores, insofar as they are designed as blind holes, into each of which the upper end of a connecting screw bolt is screwed.
  • Gluing or pouring the anchor sleeves in synthetic resin has the advantage that the holes are not specially prepared, e.g. must be provided with undercuts.
  • the disadvantage of this type of attachment is that it requires a high level of precision in manual work. The anchor sleeves must remain exactly in the intended position until the synthetic resin or adhesive has hardened, so that there is no tension in the assembled staircase, which can cause the anchor sleeves to break out when subjected to loads. ,
  • the invention has for its object to provide a simple, portable device for dressing stairs made of stone material with which the necessary holes are made, but in particular also the required undercuts of any shape in the holes - e.g. in the form of ring grooves, conical extensions or threads.
  • the movements of the heavy stairs for the finishing work should be kept to a minimum.
  • the invention is explained in more detail below on the basis of a drawing which, for example, reproduces it.
  • the drawing shows such a device in perspective.
  • the device consists essentially of a tripod 1 designed as a vertical stand, which carries at its upper end a threaded bushing 2 with a vertically arranged thread axis, a threaded spindle 3, which is screw-mounted in the threaded bushing 2 by means of a hand crank 4 arranged at its upper end, and from an engine 5 arranged axially parallel at the lower end of the threaded spindle 3, the drive axis of which is equipped with a chuck 6 for the interchangeable receiving of a stone working tool, for example a grinding wheel 7.
  • the connecting device between the threaded spindle 3 and the engine 5 consists of two superimposed plates 8, 9, which are connected to one another by a dovetail guide 10.
  • the upper plate 8 is attached to the lower end of the threaded spindle 3, while the counter plate 9 carries the engine 5.
  • the dovetail guide 10 the counter plate 9 with the engine 5 can be laterally offset with respect to the threaded spindle 3 with the upper plate 8, so that when the threaded spindle 3 is rotated, the axis of the grinding wheel 7 attached to the engine 5 moves on a circular line.
  • Any displacement position that can be reached by the dovetail guide 10 can be fixed by a locking screw, not shown in the drawing.
  • Another embodiment, not shown in the drawing, is also possible, in such a way that the two plates are connected to one another by an axle screw instead of a dovetail guide, the upper plate being fastened eccentrically to the threaded spindle and the counter plate carrying the engine.
  • the two plates are expediently designed as round disks with the same diameter.
  • the drive member of the engine 5 is an electric motor. Instead, a compressed air turbine known per se can also be used.
  • the stand 1 is equipped with a plate clamping foot 11 for a connection which can be quickly and easily produced and is connected to a step 12 to be processed.
  • a plate clamping foot 11 for a connection which can be quickly and easily produced and is connected to a step 12 to be processed.
  • the device which is much lighter than a stone step, can be clamped onto the step in the desired position.
  • the device can also be arranged on a table frame, with the steps being pushed under the clamping foot and clamped to it.
  • the threaded bushing 2 on the stand 1 is expediently rotatably mounted about the thread axis and lockable in any direction of rotation, a lock nut 13 being arranged on the threaded spindle 3.
  • undercuts e.g. Incorporate ring grooves in bores.
  • the tool is first brought to the desired depth by rotating the threaded spindle 3 with the threaded sleeve 2 locked and the lock nut 13 is tightened.
  • an annular groove is ground into the bore of the stair step by laterally displacing the engine 5 and rotating the threaded spindle 3.
  • Conical undercuts of the bores can also be produced in the same way.
  • the threaded sleeve 2 can also be arranged fixed on the stand 1, the lock nut 13 being omitted.
