  • Patent number: 11591845
    Abstract: Disclosed is a sectional door adapted to withstand high wind load and impact from flying debris. The door includes a glazing bead to secure glazing panels into frames formed by the rails and stiles of the door. The bead is connected with the frame by engagement between extensions on the bead and respective lips along the edges of the frame. The bead is pressed against the frame, causing the extension to elastically flex to allow the extensions to fit between the lips. The extensions are received in gaps formed by the lips to secure the bead in place on the frame. Force on the door cause by high winds is communicated from the glazing panel through the bead and to the frame. The door also includes reinforcements arranged along the rails to communicate forces, such as high wind load forces, from the frame to the edges of the doorway surrounding the door. The reinforcements include endcaps that increase stiffness of the rails to prevent the rails from buckling during severe weather events.

  • Patent number: 11536078
    Abstract: An entrance system is disclosed which has a movable door member having a door leaf with a first vertical edge and a second vertical edge. A sensor unit monitors a zone at or near the door leaf for presence or activity of a person or object, and captures an image of an external object at the first vertical edge of the door leaf, and processing the captured image to identify an optical code and recognize a learning mode trigger instruction encoded therein. Triggered by the recognizing of the learning mode trigger instruction, a learning mode of the sensor unit is automatically entered into, in which a distance between the sensor unit and the external object at the first vertical edge is automatically measured and a field width parameter value of the sensor unit is set based on the measured distance.

  • Patent number: 11507926
    Abstract: An automatic dock servicing system can monitor status of dock stations and/or dock station components, analyze the status to determine whether it satisfies a service condition for one or more service actions and, when service conditions are satisfied, cause the corresponding service actions to be performed. In some embodiments, a control panel can track a number of trailer loading/unloading cycles at the dock station. When the number of cycles reaches a threshold for performing a service on the dock station, the control panel can automatically initiate the service action. Some service actions that can be initiated by placing a maintenance or part request, sending control signals to a control panel or to dock station components, and/or sending messages or providing remote controls to other personnel.

  • Patent number: 11448003
    Abstract: Disclosed is a vertical profile for an automated sliding door. The profile is formed by front and rear walls connected by nose and tail walls. The nose and tail walls are thicker than the front and rear walls to provide enhanced resistance to deflection in the through-door direction. The walls are formed as an aluminum extrusion. The arrangement and thickness of the walls provides strength sufficient to withstand high wind loads without the installation of reinforcing members. Fillets may be provided where the walls are joined to lessen the tendency for the nose and tail walls deflect, further strengthen the profile.
