RETAINER SLEEVE FOR GROUND ENGAGING TOOLS
First Claim
1. A retainer sleeve configured for use in a retainer system for a ground engaging tool, the retainer sleeve comprising:
- a plurality of sections, each section being joined with an adjacent section along either a radially inner edge or a portion of a radially outer edge;
the radially inner edges of the plurality of sections forming part of a segmented inner surface configured for engagement with an outer surface of a locking member of the retainer system, the inner surface extending partially around a central axis of the retainer sleeve to form a substantially C-shaped retainer sleeve having opposite circumferential ends that are spaced from each other; and
the radially outer edges of the plurality of sections forming part of a segmented, frustoconical outer surface configured for engagement in an internal lock cavity of a ground engaging tool tip, wherein each of the sections that is joined with an adjacent section along a radially inner edge is joined to the adjacent section along the entire length of the radially inner edge, and each of the sections that is joined with an adjacent section along a portion of a radially outer edge is joined to the adjacent section along only the portion of the radially outer edge, with the remaining portions of the radially outer edges of the adjacent sections being separated from each other and angled away from each other along the remaining portions of the radially outer edges.

Abstract
A retainer sleeve configured for use in a retainer system for a ground engaging tool includes a plurality of plate-like sections, each section being flexibly joined with an adjacent section along either a radially inner edge or a portion of a radially outer edge. The radially inner edges of the plurality of sections form part of a segmented inner surface configured for engagement with an outer surface of a locking member of the retainer system. The inner surface extends partially around a central axis of the retainer sleeve to form a substantially C-shaped retainer sleeve having opposite circumferential ends that are spaced from each other. The radially outer edges of the plurality of sections form part of a segmented, frustoconical outer surface configured for engagement in an internal lock cavity of a ground engaging tool tip.

10. A retainer sleeve configured for use in a retainer system for a ground engaging tool, the retainer sleeve comprising:
-
an outer surface configured to mate with a lock cavity of a ground engaging tool tip; an inner surface extending at least partially around a central axis of the retainer sleeve, wherein the inner surface is configured to receive a lock; and a plurality of sections joined together along radially inner edges of adjacent sections or along radially outer edges of adjacent sections in an accordion-like arrangement configured such that the retainer sleeve is compressible for insertion into the lock cavity, and expandable when the retainer sleeve seats inside the lock cavity, wherein each of the sections that is joined with an adjacent section along a radially inner edge is joined to the adjacent section along the entire length of the radially inner edge, and each of the sections that is joined with an adjacent section along a radially outer edge is joined to the adjacent section along only a first portion of the radially outer edge, with the remaining portions of the radially outer edges of the adjacent sections being separated from each other and angled away from each other along the remaining portions of the radially outer edges. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)

19. A metal retainer sleeve configured for use in a retainer system for a ground engaging tool, the metal retainer sleeve comprising:
-
an outer surface configured to mate with a lock cavity of a ground engaging tool tip; and an inner surface extending at least partially around a lock rotation axis, wherein the inner surface is aligned in a direction substantially parallel to the lock rotation axis, and wherein the inner surface is configured to receive the lock rotatably about the lock rotation axis and in a direction substantially parallel to the lock rotation axis; and the metal retainer sleeve including a plurality of sections joined together along radially inner edges of adjacent sections or along radially outer edges of adjacent sections in an accordion-like arrangement configured such that the metal retainer sleeve is compressible for insertion into the lock cavity, and expandable when the metal retainer sleeve seats inside the lock cavity, wherein each of the sections that is joined with an adjacent section along a radially inner edge is joined to the adjacent section along the entire length of the radially inner edge, and each of the sections that is joined with an adjacent section along a radially outer edge is joined to the adjacent section along only a first portion of the radially outer edge, with the remaining portions of the radially outer edges of the adjacent sections being separated from each other and angled away from each other along the remaining portions of the radially outer edges. - View Dependent Claims (20)
