Abstract
A gate ring for a combination lock tumbler that has securing means on the gate ring that normally prevents rotation of the gate ring with respect to the drive member. The securing means includes a cam that alternatively releases the securing means to permit rotation of the gate ring with respect to the drive means or returns the securing means to the normal position. The securing means also comprise a flexible web on the gate ring extending adjacent the outside of the drive member. The cam is mounted between the web and a portion of the gate ring. Rotation of the cam to its normal position moves the flexible web to its normal position against the drive member, and rotation of the cam to its releasing position allows the web to move to its releasing position away from the drive member. The web is integrally formed on the gate ring, which is preferably plastic. The web is located along a chord of the circular gate ring perpendicular to a radius extending from the center of the gate ring through to the cam. The cam may have shoulders that go over a portion of the gate ring and the web to hold the cam in place. The web is mounted such that it is elastically stretched by the cam to its normal position whereby the web is urged against the cam to limit movement of the cam, and the elasticity of the web urges it to the releasing position when the cam is not urging the web to its normal position. Both the web and the drive member have gripping means for securing the drive member to the web and gate ring.
