Definitions

  • the present invention relates to a device according to the preamble of claim 1.
  • An apparatus has become known exclusively for use with hand drills, which essentially consists of a carrier tube of approximately 150 mm in length and approximately 20 mm in diameter. The outer end of this tube is fixed in a handle coupled to the spindle neck of the drill, and is then parallel to the axis of the drill spindle, respectively. aligned the drill. So the handle as equipment of the hand drill when using such a pre direction is an essential requirement.
  • the carrier tube mentioned is in turn the seat of a tubular rod which can be telescopically displaced in the carrier tube by a suspension. In the idle state, the tubular rod is fully extended by the action of the spring installed there.
  • This pipe rod has, in addition to other auxiliary devices, a mechanical information transmitter at the end, which provides information about the position of the drill bit relative to the drill spindle, that is to say relative to the drilling plane.
  • This auxiliary mechanism is extended on the wall side by a stop surface that is operatively connected to a ball joint.
  • the information about the prevailing angularity of the drilling spindle is conveyed via a pin which is firmly coupled to the flexible stop surface.
  • the visible end face of the pen is centered on a target facing the surgeon.
  • a corresponding deflection of the drilling plane of the hand drill relative to the stop surface produces a deflection of the drilling angle, the target having a gradation of up to 15 °.
  • a device for aligning the drilling angle with free use of a hand drill which essentially consists of a U-shaped support.
  • One leg of this support serves as a contact surface on the housing of the drilling machine, the other leg carries a tubular spirit level parallel to the first leg underneath.
  • An envelope circular bubble is installed in the leg at a right angle to the tubular spirit level. While the tubular spirit level conveys the angularity of the drilling spindle when drilling holes in walls, the envelope circular bubble level displays the angularity of the drilling spindle when drilling in ceilings, i.e. upwards, or in floors, i.e. downwards.
  • the invention seeks to remedy this.
  • the object of the invention is to improve the handiness and visual perceptibility of the air bubble belonging to the dragonfly in a device of the type mentioned at the outset, and to simplify the design of the device.
  • the device itself is an optical straightening device which can be used universally, that is not only in use when aligning the drilling angle in hand drills, although it should not be overlooked that this use of the invention device will probably represent its main area.
  • the device according to the invention can thus be placed and locked on any hand drill without problems, without this would have to have a special clutch mechanism.
  • the retrofitting of all existing hand drills with such a straightening device is therefore easily possible.
  • the locking can take place in various ways. It is advantageous here to design the device on the underside of the saddle rail, which serves as a support surface in relation to the axially parallel curvature of the housing of the hand drill. Such an attachment then has the further advantage that the device can be easily assembled and disassembled.
  • the device manages for all drilling levels with a single envelope circular bubble, which is arranged in an arm that can be swiveled through 360 °, and which is optically at least in every position, that is to say at every drilling angle remains observable at a viewing level.
  • the swivel arm can be locked in any position, with the relevant angular statement in terms of scale being interdependent with the alignment of the drilling spindle, so that the correspondence of the drilling plane of this angle with the optical centering of the air bubble in the envelope circular bubble is congruent.

  • FIG 8 shows a further use of the hand drill in oblique bores at about the eye level of the surgeon.
  • FIG. 1 shows a side view of a device for aligning a drilling angle with the free use of a manual drilling machine.
  • the orientation of this drilling angle for a subsequent drilling corresponding to the angle, which each drilling plane is able to detect in the 360 ° arc range, is induced by the visual statement of an air bubble belonging to a dragonfly, which is integrated in an easy-to-adjust system.
  • the device shown here consists of a device carrier 1, which is anchored non-positively via a support 2 provided with a saddle surface (see FIG. 2, item 2a) via a semi-elastic adjustable fastening strap 3 to the outer contour of the housing of a hand drill 100 parallel to the drilling axis.
