Patent number: 8448357Abstract: Couplers for attaching an accessory to an excavator arm of an excavator. Couplers having a first side for attaching the coupler to the excavator arm and a second side onto which the accessory will be coupled. The coupler includes a latch for selectively securing and releasing an attachment pin of the accessory in a jaw, groove, hook or slot in the second side of the coupler. The coupler is fully controllable from within the cab of the excavator and it allows improved security in the securement of the accessory to the coupler, i.e. preventing accidental decouplings, but while still allowing intentional decoupling operations to be carried out without undue burden.Type: GrantFiled: August 1, 2012Date of Patent: May 28, 2013Assignee: Miller UK LimitedInventors: Gary Miller, Ronald Keith Miller, Gary Pendleton, Howard Reay, Paul Grant
