WIPO Patent Application WO/2005/108684
Kind Code:
A1
Abstract:
The present invention provides a locking assembly for releasably locking a ground engaging wear member to a base structure. The wear member and the base structure both have passages extending through them and positioned to form a contiguous channel having a recessed cavity when the wear member and base structure are operatively assembled. The locking assembly comprises a resilient pin retainer sized for placement in the recessed cavity and having a central passage with a locking element. The central passage is positioned for alignment with the contiguous channel when the pin retainer is placed in the recessed cavity. The locking assembly also comprises a pin, radially sized for passage through the contiguous channel and the central passage. The pin has a complementary locking element for engaging the locking element in the central passage to impede axial motion of the pin through the channel in at least one direction, for engaging the passage of the wear member and base structure to lock the wear member to the base structure.
