    • An orthodontic device includes a bracket having a body and the body includes external surfaces. An archwire passageway is formed in the body. An aperture extends from one of the external surfaces of the body to the passageway. A pawl is attached to the body and includes stop and cam surfaces which extend into the aperture. An extendable archwire includes an adjustment portion having a locking surface and a loop-spring therein and the adjustment portion is inserted into and through the passageway. The pawl and the locking surface form a ratchet. The cam surface of the pawl interengages the extendable archwire as the extendable archwire is extended through the bracket under the application of force to the extendable archwire. The stop surface of the pawl interengages the locking surface of the adjustment portion of the extendable archwire preventing retraction of the extendable archwire upon discontinuation of the application of force.
    • 正畸装置包括具有主体的支架,该主体包括外表面。 弓形通道形成在体内。 孔从主体的一个外表面延伸到通道。 棘爪附接到主体并且包括延伸到孔中的止动件和凸轮表面。 可延伸的弓丝包括具有锁定表面和其中的环形弹簧的调节部分,并且调节部分插入并穿过通道。 棘爪和锁定表面形成棘轮。 棘爪的凸轮表面与可延伸的弓丝相接合,因为可伸缩的弓丝在施加力的作用下延伸穿过支架延伸到可延伸的弓丝。 棘爪的止动表面相互接合可延伸弓丝的调节部分的锁定表面,从而防止在停止施加力时可伸缩弓丝退回。

    • An article has a body facing engagement surface for contacting a wearer's tissue layer. The body facing engagement surface has a first state adapted to inhibit movement of the article with respect to the tissue layer of the wearer, and a second state adapted to enhance movement of the article with respect to the tissue layer. The body facing engagement surface is adapted to transform from the first state to the second state upon application of a force greater than a threshold force. The body facing engagement surface has a gripping component and a sliding component wherein the gripping component overlies the sliding component in the first state. The gripping component is disposed for engaging and gripping the tissue layer in the first state until a force greater than the threshold force is encountered which transforms the engagement surface to promote relative sliding motion between the engagement surface and the tissue layer.
    • 制品具有接触穿用者组织层的面向身体的接合表面。 身体接合表面具有适于阻止制品相对于穿着者的组织层移动的第一状态,以及适于增强物品相对于组织层的移动的第二状态。 面向身体的接合表面适于在施加大于阈值力的力时从第一状态转换到第二状态。 身体接合表面具有夹持部件和滑动部件,其中夹持部件在第一状态下覆盖滑动部件。 夹持部件被布置成用于在第一状态下接合和夹持组织层,直到遇到大于阈值力的力,其转换接合表面以促进接合表面和组织层之间的相对滑动运动。
