Abstract
A locking assembly for locking a ground engaging tool such as a point onto an adapter is disclosed. The locking assembly has a lock which can pivot between a locking position and a release position. The lock is biased into the locking position. The action of pushing the point onto the adapter moves the lock into its release position until the point is fully engaged on the adapter, when the lock returns to its locked position, now in engagement with a lock receiving recess in the adapter.

A locking assembly 16 for locking a ground engaging tool 14 over a base 12, the locking assembly 16 including a lock 18 arranged to pivot between a locking position and a release position, the lock 18 being biased into the locking position, the lock 18 having a first face 30 arranged to act against an activating surface 122, 124 of the base 12, wherein the action of the first face 30 of the lock 18 against the activating surface 122, 124 of the base 12 causes pivoting of the lock 18 into the release position.
A ground engaging tool 14 having an internal socket 82 arranged to locate over a base 12, and an external wear face 84, the ground engaging tool 14 having a lock receiving aperture 80 extending between the external wear face 84 and the internal socket 82, the lock receiving aperture 80 having a forward portion 90 and a rear portion 92, the rear portion 92 having a lateral width greater than that of the forward portion 90.
A ground engaging tool releasing means 160 having an inner end 164 and an outer end 168, the ground engaging tool releasing means 160 having a cylindrical inner portion 162 extending from the inner end 164, the inner portion 162 being arranged to be received within a pin-receiving aperture 190 in a base 12 on which a ground engaging tool 14 is attached;
- the ground engaging tool releasing means 160 having a tool-receiving formation 172 at the outer end 168;
- wherein the ground engaging tool releasing means has a cam surface 174 remote from the inner end 164, the cam surface 174 being arranged to engage with a surface 194 of the ground engaging tool 14 and to provide a releasing force to the ground engaging tool 14 when the ground engaging tool releasing means 160 is rotated.
