Tool kit

A storage device including a storage container that can be brought from a storage position in which a tool stored therein cannot be removed, to a removal position, in which the tool stored therein can be removed, with an indication element indicating the tool, the indication element being distinct from the storage container but firmly attached to the storage container and visible in the storage position. According to the invention, an indication element is provided that can be attached to the storage container in simple manner and is not only visible but also palpable, wherein the indication element is a flattened relief of the tool.

A screwdriving tool includes a gear head and a drive arm. The gear head forms a gear housing, in which a free wheel or ratchet gear having an output rotational axis is arranged. A front side of the gear head includes an output coupling, in the shape of a polygon. The drive arm can be pivoted about a pivot axis, which is substantially transverse to the output rotational axis, from a quick-action screwdriver position, in which the drive arm is in the output rotational axis, into a power-action screwdriver position, in which the drive arm extends substantially transversely to the output rotational axis and can be fixed in both pivot positions by detents. The detents can be moved from a detent position into a release position by means of an actuating member associated with the drive arm.

A chuck for receiving tools () that are operated by rotating around the axis thereof, particularly screwdriver bits, and having an insertion section () which is provided with a receiving cavity () having a non-circular cross-sectional area (). The tool can be locked in the cavity () by a holding element () which is assigned to the cavity wall in order to prevent the tool from being withdrawn from the cavity (). The holding element () can be deactivated by displacing an actuating member in a form of an actuating sleeve (). The tool () rests backwards against the cavity (). The tool () can be displaced from the resting position in the direction of the opening of the cavity () by actuating the actuating sleeve (). In order to facilitate removal of the bit, the chuck also comprises components () for releasing the face () of the bit, and a magnet () which retains the bit in the cavity from the resting position.

A process for profiling a workpiece engagement surface of a band tool, and a hand tool produced thereby, in particular a screwing tool, such as a screwdriver or wrench, pliers, a clamping tool or a file, comprising the steps of briefly irradiating the workpiece engagement surface () over a large area and/or locally with a high level of energy, such that a region of an irradiated zone which is close to the surface melts and solidifies suddenly at an edge to form a rib.

Hand tool, in particular, a screwdriver

A tool set having a screwdriver handle with a chuck for insertion and latched mounting of screwing-tool inserts provided with standard polygonal shank segments, and having screwing-tool inserts, which are insertable into the chuck and are provided with the standard polygonal shank segments, in particular bits, nuts or ratchets and extensions for drive of the latter, comprising a supplementary tool which has a plier head ( ) and a plier-handle projection ( ) which is disposed immediately behind a knuckle joint ( ) and is in form of the standard shank segment of the screwing-tool inserts, the screwdriver handle ( ) latches to the plier-handle projection by its chuck ( ), forming one of two plier arms and a blade extension ( ) which likewise has a chuck ( ), forming other of the two plier arms.

Tool set

A clamping chuck comprising a shank which has two sleeve-like shank sections ( ), one of the sleeve-like sections ( ) on an end side thereof being coordinated to a clamping section ( ) for clamping into a drive member, and the other of the sleeve-like sections ( ) on its end side being coordinated to a toolholder ( ) for mounting a tool, in particular a screwdriver bit ( ). The two sleeve-like shank sections ( ), by a torsion section ( ) formed by a torsion member ( ) coordinated to cavities of the shank sections, being twistable with respect to one another about a stop-limited angular distance (a-b), wherein the torsion section ( ) is arranged between two hexagon sections of the torsion member ( ), by which hexagon sections the torsion member is fitted without play into hexagon profile sections in the cavities ( ) of the sleeve-like shank sections ( ), and the torsion member continues, as one material integral piece into the clamping section formed as an insertion section ( ).

Clamping chuck for bits

A invention relates to a chuck having a shank which provides two shank sections (,), forms a clamping section (,) at one end for clamping in place in a drive member and forms a tool mounting (,) at the other end for mounting a tool, in particular a screwdriver bit (,), having an elastic element between the clamping-side shank section (,) and the tool-mounting-side shank section (,) for permitting a stop-limited twisting capability of the clamping section relative to the tool mounting (,). To achieve a narrow type of construction, provision is made for the elastic element to be formed as a bending spring which is bendable transversely to the axis of the chuck and connects the two shank sections to one another.

The invention relates to a force transmission structure especially for a screwing wrench with multiple corners. The invention is configured for an inner multiple cornered mating profile especially for a screw with a six cornered inner case profile. The force transmission structure is constructed with equal multiple corners whose flanks border one another in a circumferential direction. The diameter contour line of each flank possesses two convex curvature lines which are interspaced and the interspacing area recoils between the curvature lines and connecting tangent lines, the tangent lines consisting of both crowns of the convex curvature lines. In order to transmit high levels of torque, the invention provides that the section of the curvature lines between the crowns and the multiple corners is either rectilinear of its curvature is flatter than that of the convex curvature line.
