  • Patent number: 10828751
    Abstract: A screwdriver having a changeable direction freewheel lock, having a drive output member that is mounted so as to be rotatable about an axis in a bearing eye of a drive input member and has a circumferential toothing and a drive-output profile portion, and locking members that are inserted in a pocket of the drive input member and each have a locking toothing for engaging with the circumferential toothing in a manner preventing rotation. What is essential is that the locking members are two bodies that are movable relative to one another, can be displaced in an articulated manner with respect to one another and each have a switching extension which project into the same switching recess of a switching member.

  • Patent number: 7779732
    Abstract: Screwdriver handle has a storage chamber for screwdriver bits, the storage chamber being displaceable from a closed position into an open position by axial displacement of two parts of the handle with respect to one another. One handle part has a core, which is disposed in a cavity in the other handle part. The two handle parts are held in the closed position of the storage chamber by latching means movable out of a latching position by pressure on an actuating zone (8) associated with an end side of the handle.

  • Patent number: 7677391
    Abstract: A storage device for tools comprising a basic housing that is provided with a swiveling-in space for a pivotable part which is hinged to the basic housing so as to be pivotable from a storage position into a removal position. The pivotable part encompasses retaining openings for tool retaining arranged in a first row and extend into a tool accommodating compartment in the storage position. At least one additional row of retaining openings is provided that runs parallel to the first row. The retaining openings of the first and the at least one additional row are offset relative to one another in a zigzag-shaped manner.

  • Patent number: 7458296
    Abstract: The invention relates to a tool, especially a screwing tool having a handle with a chuck, and a blade, especially a screwdriver blade, that can be inserted into an insertion opening of the chuck. The blade inserted into the insertion opening is held by a detent of the chuck, said detent being displaced from a detent position to a release position by actuating a trigger. The inventive tool is characterized in that the detent comprises a detent projection which is located on a spring arm that extends in the axial direction of the insertion opening and on the periphery thereof. Said spring arm is displaced by a control element of the trigger that can be displaced in the axial direction from the detent position to the release position. The insertion opening is configured by an insertion cylinder located in a cavity of the handle. The insertion cylinder is produced from plastic and the spring arm is associated with the insertion cylinder in order to form a single part consisting of the same material.
