Abstract: The invention deals with an adjustable wrench comprising: a first jaw (8) and a second jaw (10) movable relative to the first jaw (8), wherein the second jaw (10) comprises a rack (12), a worm gear (18) movable into an engaged position wherein the worm gear (18) engages the rack (12) and wherein a rotation of the worm gear (18) causes the second jaw (10) to move relative to the first jaw (8), and into a disengaged position wherein the worm gear (18) does not engage the rack (12), a body (2) defining two surfaces, one of the surfaces comprising a first portion (14a) and a second portion (14b), the other surface comprising a third portion (16a) and a fourth portion (16b), the first portion (14a), the second portion (14b), the third portion (16a) and the fourth portion (16b) comprising a first point (140a), a second point (140b), a third point (160a) and a fourth point (160b) respectively, a biasing element (20) configured to urge the worm gear (18) toward the engaged position by applying forces on both surfaces

Abstract: A ratchet wrench comprising a ratchet head with a cylindrical bore having a central axis; a handle; a drive member (26) with a rotation axis (W-W) retained within the cylindrical bore for rotation about the central axis; and a toothed ratchet pawl (42); a cylindrical array of straight ratchet teeth arranged about one of the cylindrical bore or the drive member; and a pawl recess (36) arranged to support the pawl. The pawl may mesh with the ratchet teeth for transmission of rotation of the handle in a first direction to the drive member about the rotation axis or disengage from the ratchet teeth to decouple rotation of the handle in a second direction from the drive member. Support (37a, 37b, 46, 48, 50) for the pawl in the recess is shaped to accommodate divergence between the central axis and the rotation axis.

Abstract: A tool (10) for rotating a screw-on oil filter cartridge, the tool comprising a driving member (28, 28b); gripping jaws (12a, 12b) movable in relation to each other for gripping an oil filter cartridge; a guide arrangement (13, 14a, 14b) for guiding the gripping jaws; means (16a, 16b) for biasing the gripping jaws towards each other; and a driving mechanism (28, 28c, 24, 22a, 22b, 20a, 20b, 21a, 21b) coupled to the driving (28b) member and gripping jaws (12a, 12b) for converting rotation into movement of the gripping jaws towards each other, into engagement with an oil filter cartridge and applying either screwing or unscrewing torque thereto. The tool comprises: a locking mechanism (30, 32, 28, 24) for releasably locking the gripping jaws (12a, 12b) at a pre-determined distance from each other; and a release actuator (28a) for unlocking the locking mechanism and releasing of the gripping jaws.

Abstract: A self-contained portable electrical appliance (10) includes: an electrical unit (12); an electric power pack (14); the unit (12) including a handgrip (28) which extends in a handgrip direction Y-Y, the handgrip (28) removably connecting the unit (12) and the pack (14) in a coupled position, the handgrip (28) and the pack (14) including a first locking element (36) and a second locking element which are designed to lock together in the coupled position, the first locking element (36) being able to move between a rest position and an unlocked position. The first locking element (36) is able to move in terms of rotation between its locked and released position about an axis of rotation substantially parallel to the handgrip direction Y-Y.
