A fastener including a screw receiving element extending along a first axis and having a first end and a second end, the screw receiving element including a through hole extending through a thickness of the screw receiving element perpendicular to the first axis, the fastener further including a retention element arranged at the first end of the screw receiving element, wherein the retention element is plate-shaped and extends in a direction perpendicular to the first axis of the screw receiving element, and the retention element further includes a panel facing surface extending in a plane substantially perpendicular to the first axis of the screw receiving element, and side surfaces extending in planes substantially along the first axis of the screw receiving element.

A concrete system comprising a concrete threaded rod and a concrete part having a threaded aperture for receiving the concrete threaded rod.

A set including a first element with a cylindrical shaped part, a second element having a cylindrical shaped groove with a circular opening in an outer surface of the second element, and a mechanical locking device. The mechanical locking device includes a tongue groove, a displacement groove and a flexible tongue in the displacement groove, and is configured to lock the cylindrical shaped part to the cylindrical shaped groove. The flexible tongue is configured to cooperate with the tongue groove for locking the cylindrical shaped part to the cylindrical shaped groove. The flexible tongue is configured to be reshaped and displaced in the displacement groove during locking, and spring back to a locked position. The flexible tongue is configured to exert a spring force on the tongue groove in the locked position.

A crib assembly includes a frame to support a mattress, an enclosure having sides defining an enclosure area, and an attachment system including a first and second attachment mechanisms. A first side of the enclosure has a first end and a second end. The first end is configured to removably attach via the first attachment mechanism to a first corner of the enclosure and the second end is configured to removably attach via the second attachment mechanism to a second corner of the enclosure. The first attachment mechanism includes (a) a first bolt located at the first end of the first side or the first corner of the enclosure and (b) a first slot located at the first end of the first side or the first corner of the enclosure, opposite the first bolt. The second attachment mechanism includes (a) a second bolt located at the second end of the first side or the second corner of the enclosure and (b) a second slot located at the second end of the first side or the second corner of the enclosure, opposite the second bolt. The first and second bolts are dimensioned to be slidably received within the respective first and second slots to removably attach the first and second ends of the first side to the respective first and second corners of the enclosure.

In order to provide a connecting device for connecting two components, which is simple to manufacture and enables a stable and reliable connection of the two components, it is proposed that the connecting device comprises a main body which comprises a receiving channel extending through the main body for accommodating a fixing element, wherein the receiving channel is preferably accessible at one end by way of an insertion opening of the main body and/or preferably at a (further) end by way of a fixing opening of the main body, wherein the main body preferably further comprises an actuating opening that is different from the insertion opening and/or the fixing opening, by way of which in particular the fixing element arranged in the receiving channel is preferably accessible for the actuation thereof.

A method for manufacturing furniture using extruded polymeric honeycomb profiles, capable of providing the market with a sustainable product which can be exposed to moisture. The method includes three polymeric extruded honeycomb profiles, the extruded profile being fitted to the profile by inserting the flanges into the angled conformation, being anchored by the contact of the external flexible flaps with the flexible flaps. The union of profiles and provides an intermediate fitting allowing fixating the shelves, for example, being anchored by inserting the appendage into the angled conformations, fixating them through contact of the flexible external flanges with the external flexible flaps, allowing the formation of a three-part conjugation, being one profile and two profiles. The method allows the union of two profiles through the union of the external flexible flaps of the appendage, anchored to the internal flexible flaps of the flanges. After fitting the three profiles, which can be bottom, bases and shelves, the furniture is semi finished, the sides are mounted using profiles also fitted to the bottom, which refer to and position them, allowing the use of self-tapping screws attached to the hole of the support, allowing it to be anchored internally to the profiles, thus improving the finish in view of its honeycomb structure, after being finished with the cap to conceal the hole and the screw. The cutting edges are covered with adhesive border strips along the side walls, internal structural elements and supports.
