CONNECTING ELEMENT FOR FASTENING THE SINK TO THE WORKTOP Russian patent published in 2023 - IPC E03C1/33 

FIELD: sanitary devices.

SUBSTANCE: connecting element (1) is made for fixing the sink (10) in the worktop (20) of the desktop. The tabletop (20) of the desktop has a cut-out (21) for installing the sink. The notch (21) has a peripheral boundary surface (22). The connecting element (1) contains: the main body (2), which serves as a contact element for attaching to the sink (10), a plurality of spring elements (3.1-3.8) protruding on the first side of the main body (2), made to provide a load of direction of the main body (2) of the force (F) of the spring acting from the main body (2), and at least one fastener (4.1-4.6) , protruding on the second side of the main body (2), located opposite the first side, and designed to enter with engagement into the slot-like groove (15) in the sink (10). The angle between the engagement direction (E) of the fastener (4.1-4.6) and the direction (F) of the spring force is at least substantially 135° , preferably at least essentially 150° , especially preferably substantially 180°. The spring elements (3.1-3.8) are made in the form of tongues protruding in the edge section of the main body (2) from the main body (2), having the first continuing section (3.8a) adjacent to the edge section and the second continuing section adjoining the first continuing section (3.8b). The tongues in the first extension (3.8a) extend generally vertically to the main body (2), while in the second extension (3.8b) they extend generally parallel or at an acute angle less than 45°, preferably less than 30°, to the main body (2). The spring elements (3.1-3.8) have another, third continuing section (3.8c) adjacent to the second continuing section (3.8b) and in which the spring elements (3.1-3.8) are bent more from the main body (2) than in the second continuing section. plot (3.8b). The spring elements (3.1-3.8) differ with respect to the angle between the main body (2) and the tongue in the second extension (3.8b) and/or with respect to the length of the third extension (3.8c). The layout consists of a sink (10) and at least one located in the sink (10) of the above-described connecting element (1).

EFFECT: increased efficiency of fixation.
