Abstract

A quick coupling bucket mounting mechanism is disclosed for coupling a material handling bucket, blade, compactor, impact hammer or other attachment to the free end of a scoop arm extending from a loader or backhoe. A quick coupler is provided which is pivotally mounted to the loader scoop arm for readily receiving various types and sizes of attachments. The quick coupler has a three-leg configuration including a pair of bucket mounting legs adaptable for engagement with a bucket mounting pin. One end of each bucket mounting leg has a hook portion which cooperatively locks around lateral projections of the bucket mounting pin. A releasable latch mechanism is pivotally mounted on the third leg of the quick coupler for engagement with a complementary latch pin on the bucket. The latch mechanism is selectively rotatable to two positions. In a first position, it is aligned with and forms an opening which permits the quick coupler to be seated on the bucket latch pin. The latch mechanism is then rotated to a second position which closes the opening thereby providing a bearing mounting for the bucket latch pin in the latch mechanism. In the latched position of the quick coupler, a quick and reliable coupled connection is formed between the bucket and loader scoop arm.
