具有配合环尖端的软闭合活页夹机构

Soft close ring binder mechanism with mating ring tips

US-8573876-B2

用于活页夹，确保环闭合牢固且防止纸张脱落。

专利摘要

一种用于保持活页纸的活页夹机构，将闭合的环构件牢固地保持在一起，以防止由该机构保持的纸张意外丢失。该机构包括壳体，支撑两个铰链板以进行枢转运动，从而打开和关闭安装在板上的成对环构件。成对环构件的自由端具有互锁构造，当环构件闭合时，这些构造牢固地接合在一起。这些构造防止闭合的环构件在横向于环构件纵向中心线的所有方向上不对准。该机构还包括锁定元件，这些锁定元件与铰链板相互作用，以在环构件闭合时阻止其枢转运动。这将闭合的成对环构件的自由端保持在一起，使得环构件的互锁构造保持互锁。

Original abstractA ring binder mechanism for retaining loose-leaf pages securely holds closed ring members together to prevent inadvertent loss of pages retained by the mechanism. The mechanism comprises a housing supporting two hinge plates for pivoting motion to open and close paired ring members mounted on the plates. Free ends of the paired ring members have interlocking configurations that securely join together when the ring members close. The configurations prevent misalignment of the closed ring members in all directions transverse to longitudinal centerlines of the ring members. The mechanism also includes locking elements that interact with the hinge plates to block their pivoting motion when the ring members are closed. This holds the free ends of the closed paired ring members together so that the interlocking configurations of the ring members remain interengaged.
