<p>Coupling for detachably coupling an implement (50) to an excavator, comprising two link arms (11, 12) each having a support surface (16), and a locking means comprising a wedge support (4) attached to the implement (50) and a displaceable tension pin (7) for cooperation with the support (4), said locking means having support surfaces (24) to cooperate with the support surfaces (16) of the arms (11, 12). The locking means comprises a housing (20) extending between the arms (11, 12), in which the tension pin (7) is displaceable between free and locking positions, said housing (20) having an opening (33) for receipt of the support (4) therein when the tension pin (7) is in free position. The housing (20) has opposite pins (22, 23) to be received in openings (15) in the arms (11, 12), said pins (22, 23) and openings (15) being provided with said cooperating support surfaces (16, 24). The front end portion (40) of the tension pin (7) is positioned in a cavity (34) of the housing (20) and has a surface (41) for cooperation with a surface (43) in the cavity (34). One of the supporting pins (22) has a through-hole (36) to receive a rear end portion (45) of the tension pin (7).</p> |
