    • A T-handle latch in which a housing is designed for reception in an opening of an item to be latched. A shank of a handle is rotationally disposed in the housing, and an actuating member of the latch is fixed on the end of the shank. The shank may be received in a shank-receiving opening of the actuating member, the opening being elongate so that the actuating member may be fixed in any of a plurality of discrete transverse positions with respect to the shank. Keying elements on the shank and in the shank-receiving opening define the discrete positions and are useful in achieving initial adjustment of the latch, in preventing the latch from slipping out of adjustment during use, and in helping to prevent relative rotation of the shank and the actuating member. Return springs bias the handle toward a neutral, home position. The return springs may be housed completely within the body of the latch, thereby protecting them from accidential damage, dislodging or loss during use, installation or shipping.
    • 一个T形手柄闩锁,其中壳体被设计成用于在待锁定的物品的开口中接收。 手柄的柄部旋转地设置在壳体中,并且闩锁的致动构件固定在柄的端部上。 柄可以容纳在致动构件的柄接收开口中,该开口是细长的,使得致动构件可以相对于柄固定成多个离散的横向位置中的任何一个。 柄和柄接收开口中的键元件限定离散位置,并且可用于实现闩锁的初始调节,以防止闩锁在使用期间滑出调节,并且有助于防止柄部的相对旋转,并且 致动构件。 返回弹簧将手柄偏置到中立的原位。 复位弹簧可以完全容纳在闩锁的主体内,从而在使用,安装或运输过程中保护它们免受安全损坏,移动或丢失。
