摘要： The present invention provides a height-adjustment mechanism for an armrest. In an embodiment, a height-adjustment mechanism for an armrest includes an integral one-piece leverage body, and an integral one-piece sleeve. In an embodiment, the integral one-piece sleeve has pivot seats formed on a pair of locking arms depending from a first wall of the sleeve. These parts may be made of low cost materials suitable for integrally forming their features in an injection-moulding operation. Various features built into these parts may provide a user with a sense of quality.

摘要： A height-adjustment mechanism may include an integral one-piece leverage body; an integral one-piece sleeve; and a locking member. In an embodiment, the integral one-piece leverage body has a handle, a pair of pivot pins projecting from opposed sides, a tongue projecting rearwardly, and a resilient biasing member projecting forwardly. These parts may be made of low cost materials suitable for integrally forming their features in an injection-moulding operation. Various features built in to these parts may provide a user with a sense of quality.

摘要： A chair control mechanism has a rotatable shaft with a radially extending member abutting an actuating finger of a gas control cylinder. A slider may push a second radially extending member of the rotatable shaft in order to rotate the shaft. The slider has a tab extending into the mouth of the head of a further shaft which is rotated by a user operated handle. Thus, when the user operates the handle, the head of the further shaft causes the slider to slide.
摘要翻译：椅子控制机构具有旋转轴，其具有与气体控制气缸的致动指状件邻接的径向延伸构件。滑块可以推动可旋转轴的第二径向延伸的构件以便旋转轴。滑块具有延伸到由用户操作的手柄旋转的另一轴的头部的口中的突片。因此，当用户操作手柄时，另一个轴的头部导致滑块滑动。

摘要： A first chair part may be fixed relative to a second chair part by way of a sliding member attached to the first part which slides in a body attached to the second chair part. The chair parts are fixed relative to each other when a pin associated with the body engages in one of several apertures in the sliding member to fix the chair parts. A bent leaf spring may have an end engaging a collar on the pin. The other end of the leaf spring may be pulled to urge the leaf spring to pivot about a fulcrum created by the bend. However, if there is a force trying to move the sliding member with respect to the body (as may result from a spring between the two chair parts), a consequent shear force on the pin may be sufficiently strong to resist the urging of the leaf spring. In such case, the leaf spring will simply bend when its other end is pulled until the force between the body member and slider is relieved. The other end of the leaf spring may be pulled with an actuator device having a track bearing member with a closed loop track. An actuator member is linked to the other end of the leaf spring and has a track follower received by the track. The actuator member may be pushed against the urging of a spring to move the track follower between first and second locating positions on the track. Movement of the track follower from the first to the second locating position and back again causes no net rotation of the actuator member relative to the track bearing member.
摘要翻译：第一椅子部件可以通过附接到第一部件的滑动构件相对于第二椅子部件固定，第一部件在附接到第二椅子部件的主体中滑动。当与本体相关联的销接合在滑动构件中的多个孔中的一个孔中以固定椅子部分时，椅子部件相对于彼此固定。弯曲的板簧可以具有接合销上的套环的端部。可以拉动板簧的另一端以促使板簧围绕由弯曲部产生的支点枢转。然而，如果存在试图使滑动构件相对于主体移动的力（可能由两个椅子部件之间的弹簧产生），则销上的随之而来的剪切力可能足够强以抵抗叶片的推动弹簧。在这种情况下，当其另一端被拉动时，板簧将简单地弯曲，直到本体构件和滑块之间的力被释放。可以用具有闭环轨道的轨道轴承构件的致动器装置拉动板簧的另一端。致动器构件连接到板簧的另一端并且具有由轨道接收的轨道跟随器。致动器构件可以被克服弹簧的推动而推动，以使轨道从动件在轨道上的第一和第二定位位置之间移动。轨道跟随器从第一定位位置移动到第二定位位置并且再次返回，导致致动器构件相对于履带支承构件没有净转动。
