A door operation method, apparatus and system for a portable module for operating a door. The door operating method includes sensing a reason to at least one of open or close the door, processing the at least one of opening or the closing of the door based on the sensing, engaging a door operation mechanism, and at least one of opening or closing the door by the portable module, wherein the portable module is coupled the door.

A corner fitting for a door element, in particular for a glass door element, includes first and second fitting elements, which each include, at least sectionwise, a locating portion, which includes an intermediate layer able to contact the door element. The fitting elements delimit the restraining area, wherein a holding element is in operative connection with a connecting element, which serves for supporting the door element on a center of rotation and/or an axis. At least one exchangeable rigid distancing element is disposed between the fitting elements outside the locating portions. The distancing element forms a counter-bearing to the locating portions and the door element which can be restrained in the restraining area.

The invention relates to a drive device (1), essentially including a motor (26) and a gearbox (27, 83) and a control system (123), for the automation of a door, preferably a garage door, with a connection (120) to a force transmitting means (46) revolving within the drive track (4) and driven by means of the motor (26), wherein the gearbox (27, 83) includes a worm (29) and is equipped with two opposing motor connectors (57, 58), to which selectively a motor (26) or (28) or simultaneously both motors (26, 28) can be connected, wherein the motors (26, 28) act upon the common worm (79), the rotational movement thereof being transferred onto a worm wheel (100), which directly or indirectly acts like a gearbox onto the force transmitting means (46).

A revolving door assembly (1) comprising a central column (2) and at least one door panel (3) connected to the central column (2) and rotatably arranged around a central axis (X). The central column (2) comprises a drive unit (6) comprising a motor (13) and a gear (11). The gear (11) comprises at least one rod through hole (18). A support rod (20) passes through the rod through hole (18) and supports the motor (13). A driving base unit (5) for a revolving door assembly (1).

A power boost assembly is disclosed that can be used with a door actuator, such as a door closer. The power boost assembly is structured to store an energy during a first movement of a door and release the stored energy during a second movement of the door. In one form the power boost assembly can be structured as a module that can be added to an existing door and door closer installation. In one form the power boost assembly is used to increase a closing force imparted to a door to ensure a latching event.

The invention relates to a flap drive system for a flap which is movably mounted on a furniture carcass. The flap drive system is arranged on a sidewall of the furniture carcass. The flap drive system includes a mechanical actuating unit having an actuating arm that can be connected to the flap and an accumulator acting upon the actuating arm, and an electric drive, fastened on the mechanical actuating unit for driving the flap. The electric drive has at least one electric motor, and a gear stage which allows the transmission of force from the electric drive onto the mechanical actuating unit. The gear stage is designed as a separate component, and has a housing that is independent from the mechanical actuating unit and the electric drive or an independent mounting plate.

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).

A revolving door assembly (1) comprising a central column (2) and at least one door panel (3) connected to the central column (2) and rotatably arranged around a central axis (X). The central column (2) comprises a support structure (14) and a drive unit (6) including a motor (13) arranged to rotate said at least one door panel (3) around said central axis (X). The support structure (14) is arranged to be mounted to a bottom restriction of an opening in which the revolving door assembly is to be installed. The central column (2) comprises at least one bearing (15, 16) arranged to rotatably support said at least one door panel (3). The motor (13) and the bearing (15,16) are mounted to the support structure (14). A driving base unit (5) for a revolving door assembly (1).

A door-hinge jig for forming hinge-receiving recesses in a door edge or door frame includes an elongate body (having at least one longitudinal rail element connected by at least two rail members), at least one hinge-recess guide element (defining a guide channel and including engagement means), and at least one connector element for connecting two rail members. The engagement means engage with the at least one longitudinal rail element to set a longitudinal position of the guide element. Each hinge-recess guide element is located in a recess guide region extending continuously along a length of a longitudinal rail element. A hinge-recess guide element is selectively positionable to define a position of a guide channel in the recess guide region without obstruction or interference by a remotely located connector element.
