Abstract
Claims
1.

The connecting block element (20; 20') has a housing (21; 21'), and the housing (21; 21') is contoured on the side facing the split element (10) to guide the split element (10) in a shape-connected manner. On opposite sides of the housing (21; 21') are arranged a single locking element (22; 22') that is displaceable within at least a locking element guide hole (21.2; 21.2'), the outward-extending end (22.2) of the locking element (22; 22') being configured to engage with a locking element housing (17) provided on the inner side surface (18) of the split element (10). Both locking elements (22; 22') are displaceable outward by a common expanding element that engages between the locking elements (22; 22'). In the linked block element (20;20'), The expanding element is formed by an eccentric pin (24; 24'), which is rotatably positioned in the housing (21; 21') and oriented laterally to the locking element guide hole (21.2; 21.2') of the locking element (22; 22'), and has a cross-section of a shape other than circular in at least the region adjacent to the locking element guide hole (21.2; 21.2') of the locking element (22; 22'). A connected block element (20; 20') characterized by the above.
2. The connecting block element (20; 20') according to claim 1, characterized in that the cross-sectional region having a shape other than circular has at least one flat contact surface (24.2, 24.3) for contacting the locking element (22; 22') in the open and / or closed positions of the locking element (22; 22').
3. The connecting block element (20; 20') according to any one of claims 1 to 3, characterized in that the eccentric pin (24; 24') has a head (24.1) having a circumferential surface of a shape different from that of a circle, and the head (24.1) is shape-connected and fixed in position with respect to rotation within a matching housing (27; 27') recessed in the side surface of the housing (21; 21').
4. The connecting block element (20; 20') according to any one of claims 1 to 3, characterized in that the central axis of the eccentric pin (24; 24'), the locking element guide hole (21.2; 21.2'), and the locking element (22; 22') are arranged on the first axis of symmetry (S1) of the housing (21; 21').
5. The connecting block element (20; 20') according to any one of claims 1 to 4, characterized in that the locking element guide holes (21.2; 21.2') and the locking element (22; 22') open perpendicularly to the central hole (21.1; 21.1') of the eccentric pin (24; 24') and are arranged offset from each other in the axial direction and with respect to the second axis of symmetry (S2).
6. The connecting block element (20; 20') according to any one of claims 1 to 5, characterized in that a recessed housing portion (27) for the head (24.1; 24.1') of the eccentric pin (24; 24') is formed in the opening of the central hole (21.1; 21.1') in the housing (21; 21').
7. The connecting block element (20; 20') according to claim 6, characterized in that a locking element (29; 29') is disposed on the head (24.1; 24.1') of the eccentric pin (24; 24') and protrudes radially beyond a stepped portion provided on the eccentric pin (24; 24'), and the locking element (29; 29') is engaged with a locking slider guide (27.3; 27.3') provided in the housing portion (27) for the head (24.1; 24.1').
8. The connecting block element (20; 20') according to claim 9, characterized in that the eccentric pin (24; 24') is positioned and fixed in the axial direction within the central hole (21.1; 21.1') via the engagement of the locking element (29; 29') into the groove (27.3; 27.3') and / or retracted into a notch provided in the eccentric pin (24; 24') and via the locking element (22; 22') in contact with the contact surface (24.2, 24.3; 24.3', 24.6')
9. The connecting block element (20') according to any one of claims 1 to 8, characterized in that the central hole (21.1') is formed as a blind hole, and the eccentric pin (24') is pushable into the central hole (21.1') against the force of at least one spring element (28').
10. A Kenta shackle (100) or anchor Kenta shackle used in an anchor chain, Two interlocking split elements (10), each comprising a shorter leg (11) with a deformed structural portion (13) at its end and a longer leg (12) having a housing chamber (14) for the shorter leg, and a locking element housing portion (17) formed on the inner side surface (18) of the split element (10), A connecting block element (20; 20') according to any one of claims 1 to 9 is inserted between the two interlocking half-elements (10) and A Kenta shackle (100) or anchor Kenta shackle comprising at least the following:
