Abstract: The invention relates to a cylinder housing (2) for a pressure cylinder (1) of light-weight/hybrid construction, having a support structure (4) comprising an inner tube (6) with ends (7, 8) that are spaced apart in the axial direction, and a first and a second end piece (10, 11) in the region of one of the ends (7, 8) of the inner tube (6). A composite structure (12) made of a fiber-reinforced plastics material is arranged on an outer surface (13) of the inner tube (6). Arranged on an outer surface (16) of the first and the second end piece (10, 11) in each case in a manner distributed over the circumference thereof are a plurality of rod-like winding aids (17) that protrude from the outer surface (16).

Abstract: A cylinder for high-pressure hydraulics is disclosed, with a cylinder sleeve extending between a cylinder base and a cylinder head composed of an inner tube and an outer sleeve made from fiber-reinforced plastic placed on the inner tube. According to the invention, a weight reduction without loss of rigidity may be achieved, whereby the inner tube of the cylinder sleeve screwed to the cylinder base and joined to the outer sleeve in a thrust-resistant or shear-resistant manner engages with the cylinder head in a tensile-resistant manner.

Abstract: The invention relates to a fastening mechanism (1) for shoes, articles of clothing, tents, rucksacks etc. with a lace or tape-like tying element (2) which is inserted into a guiding tab (9) designed as a hook or eye, which at least in an end region (15) which is opposite a fastening tab (4) connected to the guiding tab (9), has a base web (16), which spaces apart the facing inner surfaces (18) of two arms (10) of the guiding tab (9) at a distance (19), whereby the inner surfaces (18) with the base web (16) form a housing chamber (20) for the tying element (2), in which a reversing element (21) for the tying element (2) is arranged, whereby the reversing element (21) is arranged at a distance (24) from the base web (16) in the direction of the fastening tab (4) and has a height (27) which corresponds at least to the distance (19).

Abstract: The invention relates to a fastening element (1) with a cylindrical casing (2) comprising an internal thread (20), which at one of its outside ends has at least one support element (4) projecting over the casing (2) in a plane perpendicular to the longitudinal middle axis (3), and at an end region (23) of the casing (2) opposite the support element (4) at least two expanding elements (29) which project over the latter in longitudinal direction and are deformable in radial direction are arranged, and the support element (4) and the casing (2) with the expanding elements (29) are made of a one-piece metal component, whereby at least one securing extension (7) is arranged on the support element (4) and the expanding elements (29) converge in the direction of a length and outside faces (28) of the expanding elements (29) opposite the support element (4) are arranged at an angle to one another.

Abstract: The invention relates to a jamming device (1) for a cord or tape fastener (30), such as e.g. shoelaces (31), for shoes, jackets, trousers and other articles of clothing, comprising a ring lug (3) for looping the fastening means (30) and a rivet strap (2) which forms a hinge bearing (14) for the ring lug (3) and which is joined to the article of clothing by means of at least one fixing element, such as for example a rivet, stitching or gluing, the rivet strap (2) having a jamming cleat (43) joined to the rivet strap and provided with an end face (35) which is surrounded by the ring lug (30) when the latter is in a position more or less parallel with a contact surface (11) in a jamming zone (29) which is made up of jamming surfaces (36) formed by the end face (35) and an inner surface of the ring lug (3) facing the end face (35), the jamming surfaces (36) being separated from each other by a gap (38) in the jamming zone (29).
