摘要： A lever operated compression latch has an elongated, hook-ended pawl carrying a longitudinal slot, and is cam guided and pin rotated while translated to engage and withdraw from a keeper cup. The compound movement of the pawl includes a lateral translation towards the keeper cup while rotating there into, followed by a lateral withdrawal to exert a compression force between the latch body which is attached to a door and the keeper cup which is attached to a door frame. A series of interconnected links is operated by a lever handle to fold into one another to provide a compact envelope when the latch is closed and to expand outwardly to open the latch and disengage the pawl from the keeper when operated by the lever. Of this series of links, a pair of release links operates in contact with one another, and rotates on respective individual pivot points to extend outwardly from the latch envelope to engage a striker plate portion of the keeper cup. This striker engagement causes the release links to push the latch and the door from a sealing engagement with the keeper and door jamb for a short distance, prior to the latch and the door thereafter being fully opened. This striker engagement of the release links also causes the latch links to fold inwardly which rotates and translates the pawl into keeper engagement and compression. This operation is facilitated with a floating spring having one end operating as a pivot member. A detent engages one of the links to provide a physical indication to the handle lever between the hard closed position and the closed about to open position.
摘要翻译： 杠杆操作的压缩闩锁具有带有纵向狭槽的细长的钩形棘爪，并且被凸轮引导并且销被转动而转动以接合并从保持杯中退出。 棘爪的复合运动包括朝向保持器杯的侧向平移，同时在那里转动，随后侧向抽出以在附接到门的闩锁体和附接到门框之间的保持杯之间施加压缩力 。 一系列相互连接的连杆由杠杆手柄操作以相互折叠以在闩锁关闭时提供紧凑的包络，并且向外扩展以打开闩锁并且当杠杆操作时将棘爪与保持器分离。 在该系列连杆中，一对释放连杆彼此接触地操作，并且在相应的各个枢轴点上旋转以从闩锁外壳向外延伸以接合保持杯的撞击板部分。 这种撞击器接合使得释放连接件在闩锁和门之后被完全打开之前将闩锁和门与保持器和门侧柱的密封接合推动一段短距离。 释放链节的这种撞击器接合还使得闩锁连杆向内折叠，其旋转并将棘爪转换成保持器接合和压缩。 这种操作通过具有作为枢转构件操作的一端的浮动弹簧来促进。 制动器接合其中一个连杆，以在硬关闭位置和关闭到打开位置之间向把手提供物理指示。

摘要： According to one aspect of the invention, a latch is configured to fix a panel relative to a frame. The latch includes a housing configured for engagement to the panel. The housing defines an aperture extending along a longitudinal axis, and further defines a cam surface facing in a direction along the longitudinal axis. A shaft extends within the aperture of the housing and along the longitudinal axis. The shaft is mounted for at least one of rotational movement relative to the housing about the longitudinal axis and axial movement relative to the housing along the longitudinal axis. A barrier wall is mounted for axial movement relative to the housing along the longitudinal axis. The barrier wall at least partially overlaps with the housing along the longitudinal axis. A shaft surface extends radially outwardly from the shaft relative to the longitudinal axis. The shaft surface contacts the cam surface defined by the housing. The shaft is configured to be coupled to a pawl for engagement of the frame. The cam surface defined by the housing is configured to guide the movement of the shaft relative to the housing along the longitudinal axis or about the longitudinal axis as the shaft is moved within the aperture defined by the housing along the longitudinal axis or about the longitudinal axis and as the shaft surface of the shaft and the cam surface of the housing move relative to one another, such that the pawl can engage or disengage the frame. The barrier wall and the housing move relative to one another along the longitudinal axis in a range of relative positions, and the barrier wall and housing together inhibit the ingress of unwanted materials into the aperture of the housing throughout the range of relative positions.

摘要： A controlled motion hinge assembly having a base with a first actuator mount, a pivot arm with a second actuator mount, a hinge pivotally connecting the base to the pivot arm to be movable between an extended position and a retracted position, and an actuator shaft. The shaft has a first end, a second end, and a threaded body extending between the first and second ends. The first end is configured to receive a drive torque about the actuator shaft axis. The second end is rotatably connected to the second actuator mount, but fixed thereto along the actuator shaft axis. The threaded body engages a threaded bore of the first actuator mount such that rotation of the body causes the first actuator mount to move along the actuator shaft axis. Also provided is a pole assembly, and a method for retrofitting a pole, with a controlled motion hinge.

摘要： A latch assembly includes a frame and a pawl including a surface for receiving a striker and being movably coupled to the frame between an open and a closed position. In the closed position, the pawl is positioned to retain the striker to the latch assembly, and, in the open position, the pawl is not positioned to retain the striker to the latch assembly. A spring guide is connected to the pawl and the frame, wherein, in the closed position of the pawl, the spring guide is configured to bias the pawl such that the pawl remains in the closed position, and in the open position of the pawl, the spring guide is configured to bias the pawl such that the pawl remains in the open position. One end of the spring guide is connected to the pawl, and the opposite end of the spring guide is unconstrained.

摘要： Aspects of the present invention provide a display support arm assembly that includes a proximal housing supporting at least one proximal shaft, a distal housing spaced from the proximal housing and supporting at least one distal shaft, and at least one link extending from the at least one proximal shaft to the at least one distal shaft. The at least one link is coupled for pivotal movement about an axis of the at least one proximal shaft. The display support assembly also includes a gas strut extending between the proximal housing and the distal housing. The gas strut provides substantially constant force throughout a range of the vertical adjustment of the display support arm. The display support assembly further includes at least one torque element associated with either or both of the at least one proximal shaft and the at least one distal shaft.

摘要： A latch includes a ferrule defining a hollow interior region and a ferrule opening that opens into the hollow interior region. A washer is positioned adjacent an end of the ferrule. The washer defines a washer opening. A stud has an elongated body extending along a stud axis, and the stud is positioned to extend through the ferrule opening and keyed to the washer opening such that the stud rotates about the stud axis along with the washer. A lever is pivotably connected to the stud. Rotation of the lever about the pivot axis causes translation of the stud along the stud axis with respect to the ferrule between a latched position, in which an end of the stud protrudes beyond a connection end of the ferrule, and an unlatched position, in which the end of the stud is contained within the interior region defined by the ferrule.
