A locking post for a closure, the post having front and rear walls joined at their sides by two side walls to form a tubular post having a generally quadratic cross-sectional shape. Each side wall has a groove therein, the groove parallel to the longitudinal axis of the post, and wide enough and deep enough to at least partly receive a locking element carried by the post. The sides of the groove also provide handles which can be gripped to move a closure the post is mounted on.

A partition system has at least one pivot joint, each pivot joint having two pivot structures with partial circular cross-sections centered on a pivot axis. Each pivot structure engages with one of a plurality of wall panels and permits the engaged wall panel to pivot about the pivot axis. A linking structure extends between and joins the two pivot structures. A stop member extends outwardly from the linking structure to limit a range within which the wall panels can pivot about the pivot axis. Each of the wall panels has a pair of parallel tabs extending substantially perpendicularly from at least one end face of the wall panel. At least one parallel tab has an end flange extending inwardly toward the second tab. The end flange snap fit onto one of the pivot structures. Each of the wall panels is pivotally connected to the at least one pivot joint.

A sealing device can be used for an edge joint between a cladding part of drywall and an adjacent floor, wall, or ceiling. The sealing device contains a one-piece base body having a carrier portion, a contact portion, and a sealing portion. The carrier portion forms a support for the circumferential side of the cladding part. The contact portion starts from the carrier portion and protrudes in a first direction angled with respect to the carrier portion in order to rest against an edge of an end face of the cladding part. The sealing portion starts from the carrier portion and extends away from the carrier portion. The sealing portion has two spaced apart webs that bridge the edge joint. Furthermore, drywall can have at least one cladding part and a sealing device of this type.
