摘要： A lock nut threadably engageable and lockingly retainable about a threaded shaft extending through a workpiece, the lock nut having at least one deformable slot disposed on a side portion thereof and disposed transversely relative to the lock nut bore axis, the lock nut also having a nut deforming member protruding from a bottom end thereof, wherein at least a portion of the nut deforming member is in substantial axial alignment with the deformable slot. The lock nut is undeformed prior to installation thereof about the threaded shaft. The nut deforming member is engageable with the workpiece to deform the lock nut upon threadably installing the lock nut about the threaded shaft, thereby retaining the lock nut thereabout, whereby the lock nut has a relatively consistent torque performance with reduced statistical spread over several installation and removal cycles of the nut about the threaded shaft. The nut deforming member is an annular portion of the skirt disposed peripherally on the bottom end of the lock nut, which may have a substantially countersunk surface. The lock nut may alternatively include a spring washer rotatably coupled thereto.

摘要： The grommet assembly includes a grommet head and a pin. The pin includes longitudinal guide channels and an enlarged head which may include undercuts formed immediately underneath the enlarged head. The grommet head includes grommet segments secured radially by radial bands with a nose band forming the tip of the grommet head. An aperture is formed between the grommet segments, with guide ridges formed on the interior arcuate walls to engage said longitudinal guide channels. The aperture further includes inwardly ramped surfaces which are forced apart by the enlarged head of the pin during insertion. Thereafter, in the fully installed position, the inwardly ramped surfaces engage the undercuts formed beneath the enlarged head.

摘要： The rings of a loose leaf ring binder are selectively locked and unlocked by a locking member which travels within a slot on the spine of the ring binder. The leaf springs of the loose leaf ring binder have notches formed below a portion of the slot. Therefore, when a W-shaped locking prong of the locking member is aligned with the notches, the leaf springs can freely flex upwardly and downwardly allowing the rings of the loose leaf ring binder to open and close. However, when the W-shaped locking prong is not aligned with the notches, the W-shaped locking prong is urged against the leaf springs thereby maintaining the leaf springs in a downward position thereby locking the rings of the loose leaf ring binder in a closed position. The locking member further includes a locking tab to maintain the locking member within a locked position within the slot.

摘要翻译： 松动叶环结合器的环通过在环形活页夹的脊上的狭槽内行进的锁定构件选择性地锁定和解锁。 松动叶环装订器的板簧在槽的一部分下方形成有切口。 因此，当锁定构件的W形锁定爪与凹口对准时，板簧可以自由地向上和向下弯曲，允许松动叶环活页夹的环打开和关闭。 然而，当W形锁定爪不与凹口对准时，W形锁定爪被推靠在板簧上，从而将板簧保持在向下位置，从而将松动叶环装订器的环锁定在闭合 位置。 锁定构件还包括锁定突片，以将锁定构件保持在狭槽内的锁定位置。
