CONNECTING BOLT AND RELATED CONNECTION FITTINGS Russian patent published in 2022 - IPC F16B12/24 

FIELD: couplings.

SUBSTANCE: invention relates to fittings having a connecting bolt and a coupling. The connecting fittings (1) contain a connecting bolt (10) having a bolt shaft (11) and a bolt head (12), which has a protrusion (13) of the bolt extending radially outward and a locking protrusion (14) located between the rod (11) of the bolt and ledge (13) of the bolt on the side opposite to the ledge (13) of the bolt, and the rear side of the ledge (13) of the bolt, facing the rod (11) of the bolt, is made in the form of an inclined surface (15), passing obliquely with respect to the longitudinal axis of the rod ( 11) a bolt, and a sleeve (20), which has a front opening (21) of the sleeve and inside the sleeve (20) both an inclined transverse surface (22) of the sleeve oriented in the direction from the opening (21) of the sleeve, and a fixing recess (23), located between the hole (21) of the coupling and the transverse surface (22) of the coupling on the side opposite the inclined transverse surface (22) of the coupling, and the transverse surface (22) of the coupling forms the wall of the side opening (24) of the coupling, open from the outside, and in the installation In the open state of the connecting fittings (1), the head (12) of the bolt is inserted into the hole (21) of the coupling and, as the protrusion (13) of the bolt, with its inclined surface (15), engages with the inclined transverse surface (22) of the coupling in the direction of insertion of the connecting bolt (10 ) and the locking lug (14) is fixed in the locking recess (23). The furniture system contains two furniture panels (2, 4) and connecting fittings (1), wherein the sleeve (20) is supported in the hole (3) of one furniture panel (2), and the connecting bolt (10) is supported in the other furniture panel (4).

EFFECT: improving connection efficiency.
