摘要： A touch bar (24) exit device (20) comprises a retractor element (50) disposed in the housing (22) for substantially restilinear movement. The retractor element (50) connects the touch bar (24) and the latch bolt (82) such that the retractor element (50) and the latch bolt (82) are moved toward the retracted position in response to movement of the touch bar (24). An electrically energizable locking mechanism (104) in the exit device (20) includes a reciprocating plunger (106) moving transverse to the retractor element (50). When energized, the locking mechanism (104) is operative to move the plunger (106) to the projected locking position to prevent retraction of the latch bolt. A time delay circuit is connected to the locking mechanism (104). A switch (120) actuated in response to movement of the touch bar (24) is connected to the time delay circuit for starting a predetermined time interval for temporarily delaying deenergization of the locking mechanism (104). When the time delay circuit interrupts power to the locking mechanism (104), the plunger (106) moves allowing the latch bolt (82) to move to the retracted position.

摘要： A removable mullion assembly comprises a fitting attached in the door opening for receiving an end of the mullion. The fitting houses a locking mechanism for selectively holding the mullion in place in the fitting. The locking mechanism comprises a latch bolt which in an extended position engages the end of the mullion and secures the mullion in the fitting. A key-operated mechanism, such as a cylinder lock, is operatively connected to the bolt for moving the latch bolt to the retracted position in response to turning the key in the cylinder. An actuating element is also provided which is activated by the end of the mullion as the mullion enters the retaining element for moving the bolt to the retracted position. The locking mechanism may further comprise a blocking element to block movement of the latch bolt from the extended position. The blocking element may be moved to the non-blocking position as the mullion is inserted into the retaining element by a release lever which is actuated by the end of the mullion or in response to turning the key in the cylinder. The new fitting allows the mullion to be mounted to the top fitting and in the door opening without the need for latch or lock components in the mullion. Having the lock mechanism permanently mounted in the fitting prevents damage and contamination to the components thereof when the mullion is removed and laid on the floor.
摘要翻译：可拆卸的竖框组件包括附接在门开口中用于接收竖框的端部的配件。该装置装有用于选择性地将竖框保持在配件中的锁定机构。锁定机构包括闩锁螺栓，该闩锁螺栓在延伸位置接合竖框的端部并将竖框固定在配件中。诸如气缸锁的钥匙操作机构可操作地连接到螺栓上，以响应于转动气缸中的钥匙而将闩锁螺栓移动到缩回位置。还提供致动元件，当竖框进入保持元件以将螺栓移动到缩回位置时，致动元件由竖框的端部启动。锁定机构还可以包括阻挡闩锁件从延伸位置移动的阻挡元件。当竖框通过由竖框的端部致动的释放杆或者响应于在气缸中转动钥匙而将竖框插入保持元件中时，阻挡元件可以移动到非阻挡位置。新的配件允许竖框安装到顶部配件和门开口中，而不需要在竖框中锁定或锁定组件。当锁定机构永久地安装在配件中时，当竖框移除并放置在地板上时，防止其部件损坏和污染。

摘要： A fire retardant door having a vertical latch stile extending the length of the stile for receiving the elements of a concealed vertical rod exit device therein along with an expanding, fire resistant material, preferably an intumescent compound, for sealing the opening when subjected to heat. The vertically reciprocating exit device rods disposed in the opening are operably connected to bolts disposed in the end of the stile openings, the bolts moveable in response to movement of the vertically reciprocating element from a retracted position within the door edge opening to an extended position to engage the door frame. The composition of the door and arrangement of the exit device elements is selected for a high fire rating, and preferably includes a wooden outer layer provided on each of the major faces of the door. A fire retardant door latch stile for housing the elements of a concealed vertical rod exit device is also provided, the stile defining a vertical opening extending the length of the stile for receiving the exit device elements, and an expanding, fire resistant material, preferably an intumescent compound, is disposed in the stile for sealing the opening when the stile is subjected to heat.

摘要： An apparatus for operating a door-latching and -unlatching device includes a thumbturn, a barrel cam, a shaft for coupling the thumbturn to the barrel cam to cause rotation of the barrel cam in response to movement of the thumbturn, a follower for the barrel cam and apparatus attaching the follower to the latch bolt to cause the latch bolt to move in response to actuation of the barrel cam. The illustrative barrel cam includes two generally diametrically opposed cam lobes such that rotation of the thumbturn either clockwise or counter-clockwise retracts the latch bolt. The follower includes a bar which lies against the cam surface of the barrel cam, and the latch bolt moving apparatus includes an actuator arm which is pivotally mounted adjacent one of its ends, the follower pin being mounted intermediate the actuator arm ends, the follower pin being supported adjacent the barrel cam, and the actuator arm further including a roller retractor actuator adjacent its other end.
