DEFINITION

Classification: 24/420

Having surface engaging element shifted by reorientation of pull tab:

(under subclass 418) Sliding device provided with a movably attached member (e.g., bar, chain) by which the pulling force necessary to shift the device along the length of the interlocking surfaces is transmitted, and wherein the locking-means* for anchoring the sliding device includes an element either separate from or movably attached to the pull member which is engaged with the interlocking surfaces when the pull member is reoriented or relocated relative to the sliding device.
