Abstract: An anti-ligature door system that utilizes an anti-ligature hinge to operatively couple the door to the door frame. The anti-ligature hinge has an assembled leaf portion formed from a pair of leaves that are operatively coupled together using one or more pins. The anti-ligature cap that is operatively coupled to the leaf portion has a body with one or more projections extending therefrom. The one or more projections may comprise a leaf projection that is configured to be located between the first leaf and the second leaf and operatively coupled to the first leaf or the second leaf. The one or more projections may further comprise a knuckle projection that is configured to be operatively coupled to a knuckle of the first leaf or the second leaf, such as by being inserted into a knuckle aperture formed by the inner surface of the knuckle.

Abstract: Door operator systems are described herein that include the use of an adaptor. It should be understood that the adaptor may be utilized in order to operatively couple separate door operator assemblies together in a double door operator system. The adaptor may include control components (e.g., switches, buttons, toggles, levers, or the like) that are used to turn the door operator system on and off. While the adaptor may be used to operatively couple two separate door operator assemblies together to form a double door operator system, the adaptor may also be used within a single door operator system. Furthermore, with respect to double door operator systems, the system may also utilize a back plate assembly comprising two or more separate back plates (e.g., two or more back plate portions).

Abstract: An anti-obstruction system for improved safety in the event a barrier becomes obstructed by objects or a person. The anti-obstruction system utilizes a double swing hinge and an emergency release stop to act as the stop for the barrier so that the barrier can only swing in one direction. The release stop may have a support member (e.g., coupled to a frame) and a stop member coupled together through the use of a cover. The stop member stops the door from swinging in two directions when the release stop is engaged and allows the door to swing past the stop member when it is disengaged. The release stop may be engaged and disengaged through the use of a release lock that has one or more projections that restrict movement between the support member, the stop member, and/or the cover when engaged, and allows for movement when disengaged.

Abstract: A door holder and release system having a release apparatus and a door holder. The release apparatus utilizes a switchable permanent magnet, a drive (motor, actuator, or the like), and an energy storage device (e.g., capacitor, battery, or the like). The door holder may be a static or dynamic door holder. When a door is held open by the release apparatus, minimum power is drawn from a power supply to maintain the charge of the energy storage device. During a disengagement event, such as a power loss event (e.g., in the event of a fire, or the like) or a disengagement request, the drive is powered by the energy storage device in order to reduce (e.g., remove, minimize, redirect, or the like) the magnetic field in the switchable permanent magnet such that the release apparatus disengages from the door holder such that the door closes.

Abstract: A door system includes a controller for controlling the door system. A user computer system transmits information to the controller over a wireless connection to modify operating parameters for controlling the operation of the door system. During installation of the door system sensors may be utilized to determine if the door system has been installed properly. The sensors may be used to identify if the door system is mounted level and plum, and to review the movement, vibration, speed, acceleration, force, or the like of the sensors, and thus, the components to which the sensors are operatively coupled in order to make adjustments to the door assembly. Furthermore, the operating parameters of the installed door system, may be cloned and provided to other door systems in order to quickly clone and distribute the operating parameters of one or more door systems to one or more other door systems.

Abstract: A door system having a linkage assembly with a drive arm and an attendant arm coupled at the ends through a gear joint. The gear joint has drive teeth on an end of the drive arm and attendant teeth on an end of the attendant arm. The drive arm is coupled to a motor in the door system that is coupled to a door, or a door frame or a wall. The attendant arm is coupled to the opposite of the door, or the door frame or the wall to which the door system is coupled. When the door system is installed on the push side or the pull side of the door the drive arm and the attendant arm are parallel with the door and the upper door frame. During operation the motor transfers the torque from the motor through the gear joint to open the door.

Abstract: A detection sensor or a user device is used to aid in providing authentication and activation of a door system when a user tries to access the door for ingress and egress. Operating parameters of the door systems may be set to allow ingress and egress only when a user is identified and authorized. As such, the operating parameters of the door systems may include authentication and activation parameters such that the door systems are controlled, at least in part, based on the presence of a user and/or a user device and the identification of the specific user. As such operating parameters may be different for different users or types of users. Moreover, the user device may be used to authenticate a user and control ingress and egress through the door automatically or through an authentication action taken by the user.

Abstract: A door closer and assist system that utilizes a door closer and door assist that aids in reducing the force required to open the door and/or increasing the force for closing the door. The door closer may be installed along with the door assist, or the door assist may be installed to any door closer that is already installed to a door. The door assist may include a track and a drive assembly having a motor assembly, a carriage, and a drive shaft. The motor assembly may have a drive train, a motor, and a controller. One or more sensors may be used to determine when to activate the motor to aid in opening and/or closing the door. The door closer and assist system allows for a door to be closed with a force that is greater than or equal to the force required to open the door.

Abstract: A door closer may utilize a door closing device (e.g., spring) and a force adjustment device (e.g., a motor) in order to allow for manual door opening and assisted door closing. During operation, as a door is manually opened, the spring is loaded (e.g., compressed or tensioned) above its pre-loaded closed position state. Once manual opening is completed, the spring that is loaded during opening begins returning to the pre-loaded closed position state, and thus, moves the door automatically towards the closed position. Depending on the pre-loaded spring setting, the closing force of the door may not be enough to close the door, or to close the door with the preferred force. As such, during closing a controller may engage a motor not to drive the door directly, but to increase the pre-load of spring to increase the closing force in order to allow the door to close as preferred.

Abstract: A dampener for an exit device may be disposed between a portion of an exit device actuator and an exit device chassis so that the dampener dampens vibrations to reduce noise of the exit device and/or inhibit unintentional movement of the actuator to an actuated position. The dampener may be composed at least partially of a viscoelastic material.

Abstract: A patch fitting coverplate or cap for a patch fitting that extends a pivot point centerline of the patch fitting. The patch fitting coverplate may be constructed as a retrofit cover to integrate a patch fitting of one standard pivot point centerline to a door pane of another standard pivot point centerline. A patch fitting assembly including the patch fitting coverplate and patch fitting may also include buffers to fill in the interior portion between the extended patch fitting coverplate and the patch fitting. The patch fitting may be tapered at an edge close to the pivot axis of the door pane for smooth actuation of the door pane.

Abstract: During operation of the door system one or more sensors may be utilized in order to monitor the operation of the door assembly (e.g., door system, door, frame, etc.), review the operating parameters, troubleshoot potential issues, schedule and monitor service requests, review and take actions for potential security threats, and/or the like. Consequently, users may determine if the door system operates the door in accordance with the desired operating parameters by reviewing the movement, vibration, speed, acceleration, force, or the like based on the sensor information captured and use the information to adjust the door assembly. Notifications regarding the operation of the door systems may be sent automatically and/or in response to requests from users. The users may utilize one or more applications and interfaces thereof to remotely connect to the door systems in order to review and analyze the sensor information and take the desired actions.
