Abstract: A joint assembly includes a structural body having a key which projects cantilevered from an abutment surface. The key includes a stem with a first stem portion having a reduced transverse encumbrance, and a second stem portion from which fins project and define locking surfaces. A seat body includes an abutment counter-surface facing the abutment surface. A seat is formed by opening from the abutment counter-surface, which delimits a key entry slot. A first seat portion proximate the entry slot allows insertion of the key if the fins are aligned with the entry slot. A second seat portion internal and opposite the entry slot widens to allow free rotation of the key. The seat body forms locking counter-surfaces having an inclined plane portion moving away from the entry slot so that key rotation brings the abutment surface in force-contact against the abutment counter-surface, creating a firm frictional fit.

Abstract: A door (1) for an oven (100) for closing and opening a cooking chamber (120) of the oven (100), comprising a frame (20) able to be hinged to the oven (100), and a first panel (30) fixed to the frame (20), comprising at least a second panel (31,32) associated to the frame (20) removably by means of jointing fastening elements (24,213,222).

Abstract: A modular frame structure (1) of a partition wall made of glass panes, or other pane material, or pane (7), comprises: —a side assembly (2) to form at least one of the lower side, or base, of the frame structure (1), or the upper side, or cross bar, of the frame structure (1), or a mount, or column member arranged between the base and the cross bar, of the frame structure (1); —said side assembly (2) comprising—a track (3) suitable to firmly connect to the ceiling or the floor or a support structure, said track (3) having body extending along a preset first longitudinal extent (X-X); —said assembly further comprising a telescopic section bar (4), suitable to be connected to said track (3); —said telescopic section bar (4) forming at least one invitation and coupling seat (5) and being suitable to receive a coupling section bar (6) secured to said pane (7); —said invitation and coupling seat (5) being defined by a sliding and resting wall (8) that, with an edge (9) thereof, defines a seat opening (10) through
