The invention relates to an anchor sleeve (perforated sleeve 10) for injection fixing of an anchor bar, not represented, in a drilled hole, not represented, in masonry. According to the invention, the anchor sleeve (10) is provided with support ribs (18), extending inwards for the anchor bar and the support ribs (18) are arranged along chord directions instead of radially. The support ribs (18) hold an anchor bar coaxially in the anchor sleeve (10) and permit a diameter matching by means of deformation. A greater diameter adjustment is achieved by means of said arrangement of the support ribs (18) in chord directions, whereby the support ribs (18) may be more easily pushed to the side.

The invention relates to a case (10) for storing a pair of spectacles (54) in an intermediate space between a spectacle holder (56) and a pivoting housing cover (20). When the housing cover is closed (20), two elastic bands which are stretched inside the housing (12) of the case (10) below the cover (20), press the spectacles against the inside of the housing cover (20) so that the spectacles (54) are firmly clamped in the housing cover(20) and do not rattle.

The invention relates to a drill bit (10) for producing drilled holes with relief cutting, whereby the drill bit (10) comprises a flexible bit stop (22). According to the invention, the bit stop (22) is provided in the form of a sheet metal stamped and bent part, for example, made of spring steel with spring tabs (26) projecting toward the brickwork and with clip elements (28), which project in the opposite direction and hold the bit stop (22) on a collar (20) of the drill bit (10) The invention makes it possible to simply and economically produce said bit stop (22) that easily withstands heating caused by the drilling hammer.

The invention relates to a straddling dowel comprising a dowel sleeve and a straddling screw (10). According to the invention a rear flank (20) of the screw thread (18) of the straddling screw (10) is oriented, in the direction of screwing, at a flat angle of approximately 9° in relation to the direction of the axis of the straddling screw (10) and the screw thread (18) is formed with a large thread pitch. When the straddling screw (10) is impinged upon in the direction of extraction, the rear flank (20) acts in the manner of straddling cone-shaped elements which are arranged axially behind each other and the sleeve of the dowel is expanded. The straddling dowel is post-expanded when the bore hole is widened. In order to prevent the straddling screw (10) from rotating out of the sleeve of the dowel, anti-rotation flanks (26) which are oriented both radially and in a longitudinal direction are provided on the screw thread (18), said flanks pressing into the dowel sleeve during expansion and thereby preventing the straddling screw (10) from rotating out of the dowel sleeve.

The invention relates to an expansion bolt (10) for anchoring in a cylindrical borehole (40). According to the invention, the expansion bolt (10) is configured with a tubular bolt base part (12) to which a hollow conical expansion section (22) is moulded by forming. An expansion sleeve (14) that is bent from a sheet is placed on said expansion section. The expansion bolt (10) is anchored in the borehole (40) by the axial displacement of the expansion sleeve (14) on the expansion section (22). The expansion bolt (10) expands further if the borehole (40) expands, for example as a result of cracking.

The invention relates to a holder (10) for a drinks container. The aim of the invention is to accommodate said holder (10) in a space-saving manner. According to the invention, the holder (10) is configured as a recess (14) in a dashboard (12) of a motor vehicle for instance. The holder is provided with an ashtray (20) which can be pivoted into and out of said recess (14). When the ashtray is in the holding position, i.e. pivoted out of said recess (14), said ashtray (20) laterally closes the recess (14) in such a way that a mug (44), for instance, can be placed into the recess (14). The advantage of the invention is that the space for receiving the ashtray (20) is also used for placing the mug (44).

The invention relates to a connector (10) which is used to connect assembly rails (18, 19, 20, 21) in a cross joint. In order to enable time-saving assembly carried out by a fitter, the joint connector (10) is provided with a connector device (14) consisting of an angle piece (34) with two limbs (39,40). One limb (40) of the angle piece (34) can be suspended in an opening (42) on the joint connector and the other limb (39) can be fixed to the assembly rail (18,21) inserted into a receiving element (16) of the joint connector (10).

The invention relates to a shear connector consisting of an anchor rod (1) which can be anchored in a bore hole (12) of a component (13) by means of a jointing mass. Said rod comprises several cone sections (3a, 3b, 3c) which are distanced from each other by means of cylindrical sections (6a, 6b), and which expand in the direction of the inserted end (4). The cylindrical sections (6a, 6b) are 0.5 to 2.0 times as long as the cone section (6a, 6b) which connects to the respective section in the direction of the inserted end (4). A solid concrete shell (14) is thus achieved, once the jointing mass has hardened, said shell exhibiting high drawing values on slippage of the cone sections (6a, 6b, 6c) in the hardened concrete shell (14) following the expansion of the bore hole through fissuring. The inventive shear connector is particularly suited to anchoring in the zone which is subject to tensile force.

The invention relates to a fixing element for double glass plates. Said element consists of a threaded bolt (2) with an expansion cone (3) that is arranged at the front end. A ring-shaped expansion element (5) can be slid onto said cone in order to expand a bore of the glass plate (6) that is at the back, whereby the bore is provided with an undercut (10) in the area of the bottom of the bore. The aim of the invention is to prevent a direct contact between the fixing element consisting of steel and the glass surface in the area of the expansion element as well as in the area of the threaded bolt. To this end, a cap (9) that consists of soft plastic and rests on the front end of the threaded bolt (2) is put over the expansion element (5). Furthermore, a distance sleeve (12) made of hard plastic that rests on the glass plate (6) which is at the back and that penetrates the glass plate (15) which is at the front is arranged on the shaft of the threaded bolt (2). Said sleeve is provided with a section (13) that supports the expansion element (5) and that engages with the bore (11) of the glass plate (6) which is at the back.
