Abstract

Sleeve guide for screwdriving tools: by means of a sleeve fitted over a screwdriver and the head of the screw to be turned, the screwdriver (turned manually or mechanically) is fixed centrally in the screw slot. This prevents lateral slipping and off-centre screwing, which damages screwdriver and screw. <IMAGE>

Description

Das Instrument besteht aus einer länglichen Hülse (1), die auf einen Schraubendreher (4) aufgeschoben ist. Durch die fest an der Hülse befindliche Manschette (3), welche auf dem Schraubendreherschaft gleiten kann, und die fest am Schraubendreherschaft befindliche Abrutschsicherung (2), über die die Hülse gleiten kann, ist die Hülse auf dem Schraubendreher in der Achse des Schraubendrehers fest fixiert, jedoch in Achsenrichtung verschieblich und von den Drehungen des Schraubendrehers frei.The instrument consists of an elongated sleeve ( 1 ) which is pushed onto a screwdriver ( 4 ). The sleeve ( 3 ), which is fixed on the sleeve and can slide on the screwdriver shaft, and the anti-slip device ( 2 ), which is fixed on the screwdriver shaft and over which the sleeve can slide, firmly fix the sleeve on the screwdriver in the axis of the screwdriver , but slidable in the axial direction and free from the rotations of the screwdriver.

Die Klinge des Schraubendrehers (5) kann nun in den Schlitz einer Schraube (6) eingesetzt werden, indem der Schraubendreher auf die Schraube axial aufgesetzt wird (7), dann wird durch Überstülpen der Hülse die Schraubendreherklinge mittig im Schraubenschlitz fixiert und kann anschließend bei Drehung des Schraubendrehers unter Druck in Richtung Schraube (9) nicht mehr abrutschen.The blade of the screwdriver ( 5 ) can now be inserted into the slot of a screw ( 6 ) by placing the screwdriver axially on the screw ( 7 ), then by screwing the sleeve over, the screwdriver blade is fixed in the center of the screw slot and can then be turned of the screwdriver no longer slip under pressure in the direction of the screw ( 9 ).

Wenn durch Dreh- und Druckbewegung (9) die Schraube nun in den Werkstoff, z. B. eine Wand (8) eindringt (11), wird die über den Schraubenschaft vorgeschobene Hülse allmählich zurückgedrückt und ruscht über dem Schraubendreherschaft zurück (10).If by turning and pushing ( 9 ) the screw in the material, e.g. B. a wall ( 8 ) penetrates ( 11 ), the sleeve advanced over the screw shaft is gradually pushed back and rushes back over the screwdriver shaft ( 10 ).

Claims (2)

Hiermit wird Patentanspruch erhoben für die Hülsenführung bei Schraubendrehgeräten, gekennzeichnet durch
  • die über einen üblichen Schlitzschraubendreher (oder "Schraubenzieher") gestülpte, verschiebliche Hülse.
  • Bei der Anwendung dieses Instrumentes wird die Schraubendreherklinge in den Schlitz der Schraube ein­ gesetzt. Durch Überstülpen der auf dem Schraubendreher­ schaft verschieblichen Hülse, welche vorgeschoben wird über den Schraubenkopf wird nun ein seitliches Abrutschen des Schraubendrehers aus dem Schlitz der Schraube verhindert.
  • Dadurch werden auch Scherkräfte verhindert, die bei einer nicht mittigen Einsetzung des Schraubendrehers in den Schraubenschlitz zu Schäden an der Schraube bzw. dem Schraubendreher führen können.
  • Von besonderer Bedeutung ist dies bei Einsatz von hohen Kräften bei der Verschraubung, wie sie etwa bei der Anwendung elektrischer Schraubendreher auftreten.
Herewith, claim is made for the sleeve guide in screwdrivers, characterized by
  • the sliding sleeve, which is slipped over a conventional flat-blade screwdriver (or "screwdriver")
  • When using this instrument, the screwdriver blade is inserted into the slot of the screw. By slipping on the sleeve which is slidable on the screwdriver shaft and which is pushed forward over the screw head, the screwdriver is now prevented from sliding sideways out of the slot in the screw.
  • This also prevents shear forces, which can lead to damage to the screw or the screwdriver if the screwdriver is not inserted centrally into the screw slot.
  • This is particularly important when using high forces when screwing, such as occur when using electric screwdrivers.
Die zur Achsenfixierung der Schrauberachse mittig über die Schraubenachse auf dem Schraubendrehstift angebrache Hülse - für alle Formen manueller oder instrumentell angewendeter Schlitzschraubendreher soll in diesem Patent geschützt werden.The for fixing the screwdriver axis in the middle over the screw axis the sleeve attached to the screw - for all types of manual or Slotted screwdriver used as an instrument is intended in this patent to be protected.
