Abstract: A securing system for a helmet has a forehead band having two guiding installations and two neck band portions having in each case one counter guiding installation that corresponds to one of the two guiding installations of the forehead band. Each of the counter-guiding installations for repositioning the respective neck band portion in relation to the forehead band is disposed so as to be displaceable on the corresponding guiding installation.

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.

Abstract: A helmet is provided including a helmet shell for spatially defining a head receiving space and an adjustable ventilation arrangement which is in flow-connection with the head receiving space. The ventilation arrangement includes at least one first ventilation device having at least one first ventilation channel running in the helmet shell and a first slider device, which is assigned to the at least one first ventilation channel and which for varying a flow cross section of the at least one first ventilation channel is displaceable between a ventilation channel opening position and a ventilation channel closing position along the helmet shell. The at least one first ventilation device moreover includes a first latching device for latching the first slider device to secure it in at least one predefined latched position.

Abstract: A screw tool having a gear head, which has a freewheel gear, having an output shaft, which is inserted in a non-rotatable but displaceable manner in an output opening and can be moved to and fro between a right-hand screw position and a left-hand screw position in each case by use of axial displacement, wherein in each case a different end section of the output shaft projects out of the gear head, having at least one locking mechanism to secure the position of the output shaft in the respective screw position and/or around a screw output element on the output shaft. As a development which is advantageous for use, the at least one locking mechanism can be moved from a locking position to a release position by pressure on an actuation element arranged on the end face of the output shaft.

Abstract: A device for storing tools, in particular screwdriving tools, having a planar main body which has an inner side and an outer side, wherein holding devices for retaining the tools on the main body are provided on the inner side, wherein the main body is divided up into surface portions by a number of hinges, the surface portions being foldable about the hinges from a tool-removal position, in which the surface portions are located substantially in one plane, into a storage position, in which the outer sides of the surface portions form planar surfaces of a polygonal solid body.

Abstract: A socket spanner including a drive head, which forms a polygonal profile opening that can be plugged onto a polygonal bolt head or a polygonal screw nut, and includes a retaining element enclosed in a window of the wall of the polygonal profile opening, which retaining element is acted on by a spring element arranged outside the wall. In order to simplify such a socket spanner in terms of manufacturing technology and/or to improve it in terms of handling, it is proposed that the spring element is a shrinkable tube which is shrink-fitted on the wall.

Abstract: A screw tool having a gear head, which has a freewheel gear, having an output shaft, which is inserted in a non-rotatable but displaceable manner in an output opening and can be moved to and fro between a right-hand screw position and a left-hand screw position in each case by use of axial displacement, wherein in each case a different end section of the output shaft projects out of the gear head, having at least one locking mechanism to secure the position of the output shaft in the respective screw position and/or around a screw output element on the output shaft. As a development which is advantageous for use, the at least one locking mechanism can be moved from a locking position to a release position by pressure on an actuation element arranged on the end face of the output shaft.

Abstract: The aspects enable a multi-core processor or system on chip to determine a low power configuration that provides the most system power savings by placing selected resources in a low power mode depending upon acceptable system latencies, dynamic operating conditions (e.g., temperature), expected idle time, and the unique electrical characteristics of the particular device. Each of the cores/processing units treated in a symmetric fashion, and each core may choose its operating state independent of the other cores, without performing complex handshaking or signaling operations.

Abstract: A wrench including an inward opening that has a multi-point configuration for partially-surrounding engagement in a torque-transmitting manner on a polygonal profile of a nut or a bolt head, a radial jaw opening being associated with the inward opening and at least two corners of the multi-point configuration each having a stop for a portion of an end face of the polygonal profile. In order to extend the range of use of the wrench, the jaw opening has oppositely-disposed jaw cheeks as the opening of an open-end wrench for torque-transmitting engagement on the polygonal profile, the jaw cheeks extending over the corners of the multi-point configuration on only one wide face (of the wrench).

Abstract: 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.

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.

Abstract: A chuck for receiving tools (1) that are operated by rotating around the axis thereof, particularly screwdriver bits, and having an insertion section (3) which is provided with a receiving cavity (2) having a non-circular cross-sectional area (3). The tool can be locked in the cavity (2) by a holding element (4) which is assigned to the cavity wall in order to prevent the tool from being withdrawn from the cavity (2). The holding element (4) can be deactivated by displacing an actuating member in a form of an actuating sleeve (5). The tool (1) rests backwards against the cavity (2). The tool (1) can be displaced from the resting position in the direction of the opening of the cavity (2) by actuating the actuating sleeve (5). In order to facilitate removal of the bit, the chuck also comprises components (15, 16, 17) for releasing the face (1) of the bit, and a magnet (9) which retains the bit in the cavity from the resting position.
