摘要： An electromagnetic doorholder for retaining a door in an open position by magnetic interaction with an armature secured to the door. The doorholder includes a core having a face confronting the armature and a coil of wire surrounding the core. A cup having an inside diameter somewhat greater than the coil outside diameter receives the coil, the core extending from the face to the cup bottom. A power control circuit including a resistor circuit controls electrical power supplied to the coil, the power control circuit being mounted on a circuit board situated between the coil rear surface and the cup bottom. The resistor circuit being situated in sufficiently close proximity to the cup bottom for transfer of heat from the resistor circuit to the cup. The power control circuit also includes a low resistance circuit coupled to the resistor circuit, the low resistance circuit including a fusible link, the fusible link being selected to carry current when the power input terminals are coupled to a lower voltage power source and to stop carrying current when the power input terminals are coupled to a higher voltage power source.

摘要： A door lever assembly having a locked and an unlocked position includes a trim housing and a lever handle and cam rotatably connected to the trim housing. A rotatable shaft extends between the lever handle and the cam, with the shaft defining a connection groove therethrough to provide access to a shaft interior. The shaft interior is configured to accept a pin for connecting the cam and the shaft. This pin can be wedgably disconnected following controlled slippage of frictional wedge surfaces in response to excessive force applied to rotate the cam.

摘要： A mullion assembly mountable in a door frame includes a bottom fitting attached to a floor and a top fitting attached to the door frame above the bottom fitting. The top fitting supports a latch engagement assembly for engaging a latch assembly positioned in a mullion cavity of a mullion. The latch assembly has a latch extendable from the mullion cavity to engage the latch engagement assembly supported by the top fitting and hold the mullion in a fixed position. Retraction of the latch is controlled by a key lock assembly connected to the latch assembly through an actuating link assembly. The key lock assembly permits key controlled disengagement of the latch from the latch engagement assembly, followed by temporary removal of the mullion from its position in the door frame.

摘要： An overhead mounted door holder assembly for attachment between a door jamb and a door, to hold the door in an open position, includes a jamb bracket attached to the door jamb and a jamb arm pivotally attached to the jamb bracket. A channel assembly having a longitudinally extending channel is attached to the door, and first and second end caps are attachable to opposing ends of the channel assembly, with each end cap being held by a retaining key in locked connection with the channel assembly. The first and second end caps are configured to allow alternate positioning of the channel assembly inset in a top of the door or attached to a side of the door. A hold open stop is fixably held in the channel of the channel assembly. The hold open stop is configured to have a stop element for engaging a slide assembly pivotally attached to the jamb arm and positioned for longitudinal movement in the channel. The slide assembly is configured to engage the stop element of the hold open stop and hold the door in an open position. The force required to engage the hold open stop and the slide assembly is determined by the position of an adjustment wedge.

摘要： A mullion assembly mountable in a door frame includes a bottom fitting attached to a floor and a top fitting attached to the door frame above the bottom fitting. The top fitting supports a bolt engagement assembly for engaging a lock assembly positioned in a mullion cavity of a mullion. The lock assembly has a bolt extendable from the mullion cavity to engage the bolt engagement assembly supported by the top fitting and hold the mullion in a fixed position. Retraction of the bolt is controlled by a key lock assembly that allows controlled access disengagement of the bolt from the bolt engagement assembly, followed by pivoting movement of the mullion away from its upright position in the door frame.

摘要： An electromagnetic door lock assembly employs an electromagnet positioned in a frame adjacent to a door, and an adjustable armature assembly positioned in the door for interaction with the electromagnet. The armature assembly includes an armature plate having a pair of shear low-cost, replaceable elements that initially engage the electromagnet. A backing plate is situated adjacent to the armature plate, and a stem coupling the backing plate to the armature plate includes a spring biasing the backing plate and armature plate toward each other. A mounting portion for mounting the armature assembly to a door to be locked is provided with adjusting screws for adjustably positioning the backing plate at a fixed position with respect to the mounting portion so that the armature plate is positioned at a first position for optimum interaction with the electromagnet, the screws having elongated heads for maintaining the relative alignment between the armature plate and the mounting portion as the armature plate moves between the first position and a position contiguous to the electromagnet.

摘要： The Device is of the push pad type having a translating action rod which is biased in the latch bolt-extended position. An abutment is fixed to the action rod to receive thereagainst the extending plunger of a shock absorber which is removably coupled to an open guide base. The base is mounted on a base plate to support action rod operating bellcranks, and to support the action rod therein also. A shock absorber holder is clasped to the guide base, and the cylinder of the shock absorber, in which a viscous fluid is confined, is engaged by the holder to direct the plunger toward the abutment. In the depicted embodiment, the plunger resists retraction, to decelerate and damp the return of the push pad and action rod to their at-rest positions and, consequently, to suppress the operating noise of the panic exit device.

摘要： The mechanism is configured to operate both a primary latch bolt and secondary latches, and provides for immediate, ready egress for the side of a door to which the mechanism is mounted, but offers high security for the other, outside of the door. The latch bolt is directly controlled by a first linkage, and the secondary latches are directly controlled by a second linkage. During egress, both linkages translate together, via a pin connection. However, a lost motion arrangement prevents retraction of either the bolt, or the secondary latches, if the other is compromised (or operated by a key or combination). From the outside, high security side of the door, the latch bolt and the secondary latches must be retracted together.
摘要翻译：该机构被配置为操作主闩锁螺栓和辅助闩锁，并且为安装机构的门的侧面提供立即准备的出口，但是在门外提供对另一个的高安全性。闩锁由第一连杆机构直接控制，二次锁闩由第二连杆机构直接控制。在出口期间，两个连接通过引脚连接平移在一起。然而，如果另一个被破坏（或者由钥匙或组合操作），则丢失的动作装置可防止螺栓或辅助闩锁的退回。从外部，门的高度安全侧，闩锁螺栓和辅助闩锁必须缩回到一起。
