A spacer for connecting a suspension component to a frame of a bicycle includes a spacer body and a flexible portion disposed at one end of the spacer body and configured to exert an axial bias force under compression. The spacer body and the flexible portion form a unitary part.

A collet to feed and fasten cylindrical rivets includes an inlet unit that accepts and supports the rivet, a first feeding unit connected from the inlet unit and configured to feed the rivet, a second feeding unit connected to the first feeding unit opposite to the inlet unit and configured to feed the rivet, and an outlet unit that is connected to the second feeding unit opposite to the first feeding unit and supports the rivet that is fed to it. The inlet unit and the first feeding unit have at least two first slots at opposite angles, the second feeding unit and the outlet unit have more of second slots than the first slots, and when the rivet enters the first feeding unit, the second slots are closed by the opening of the first slots.

A rear wall/panel connector includes a stud, which has a receiving groove and two walls projecting vertically from the stud on both sides of the receiving groove. The two walls each have an opening configured for screwing in a screw. One of the two walls forms an arm of a rocker which is mounted on the stud wherein it is pivotable between a starting position and an end position about an axis which is parallel or almost parallel to the longitudinal direction of the receiving groove. The inside of the second wall is positioned obliquely outwards with respect to the longitudinal center plane of the receiving groove in the starting position and extends parallel to the longitudinal center plane in the end position. The other rocker arm projects outwards over the stud, at least in the end position.

An apparatus for use with a sheet of rigid support material at a hole formed therein through a thickness of the sheet to provide an anchoring point at a proximal face of the sheet for anchoring an object thereto comprises a frame member supporting a face-engagement member for engaging a distal face of the sheet which is spaced from the proximal face by the thickness of the sheet, so as to resist removal from within the hole by the object anchored to the apparatus, and a buttress member also supported on the frame member for buttingly engaging a peripheral wall of the hole so as to resist movement transversely to a thickness direction of the sheet.

A measuring device is provided, configured to be mounted on or in an opening of a container, the measuring device including: a flange configured to rest on a top of a wall of the container enclosing the opening of the container; and a clamping or spreading device configured to adjust and apply a clamping or spreading force to an underside of the wall or to an inside of the opening to secure the flange to the opening. A flange configured to be mounted on or in an opening of a container, and a container, are also provided.

A hydraulic coupling device includes an inner sleeve having a tapered outer surface, an outer sleeve having a tapered inner surface mounted on the tapered outer surface of the inner sleeve, a nut screwed onto the inner sleeve, and a cylinder formed separately from the outer sleeve and secured to the outer sleeve. The cylinder abuts axially against the outer sleeve to form a j oint. At least part of the nut extends into the cylinder, and the cylinder, the nut and the outer sleeve together delimit a chamber. A friction enhancing coating is provided between the cylinder and the outer sleeve and/or at least one protrusion extends from one of the outer sleeve or cylinder into a complementary recess in the other of the outer sleeve or cylinder.

The invention relates to a tensioning ring (1) having a tensioning section (3), the tensioning section (3) comprising a wedge element (6), a guide member (7a) and a tensioning screw (5), wherein a width of the tensioning section (3) and thus a circumference of the tensioning ring (1) can be changed by tightening the tensioning screw (5), for which purpose the wedge element (6) is guided at the guide member (7a) and is movable in this guide along a movement way (20a) at the guide member (7a) by tightening the tensioning screw (5), the movement way (20a) having a portion in a width direction (4) determining the width of the tensioning section (3), wherein the wedge element (6) and the guide member (7a) engage in one another with an undercut in such a way that they are held together in a form-locking manner with respect to the width direction (4).
