A hold-open arrester arrangement has a low power consumption, and therefore a battery lifetime is long in the embodiments of the invention utilizing the battery. The hold-open arrester arrangement has a hold-open arrester arrangement having a hold-open function to hold a door open. The arrangement has also an electric release arrangement. The release arrangement is arranged to release the hold-open function in a fire alarm situation. The hold-open arrester arrangement comprises a sliding block and an arrester unit. The sliding block is connectable with a slide rail in a sliding manner and also pivotable connectable to an arm of a door closer. The arrester unit is connectable to the slide rail and has a body, said electric release arrangement, and said hold-open function with the sliding block.

An exemplary door closer includes a body, a regulation screw, and an indicator. The body includes a surface and a cavity extending from the surface into the body, and the cavity includes an internal threading. The regulation screw is mounted in the cavity and includes an external threading engaged with the internal threading. The indicator is engaged with the regulation screw and positioned at least partially within the cavity. The indicator is positioned to project beyond the surface when the regulation screw is withdrawn to a reference position relative to the body.

A furniture fitting for movably mounting a furniture flap, in particular a two-part furniture flap, on a furniture carcass includes a main part which is or can be connected to the furniture carcass; a mounting device which is or can be connected to the furniture flap; and at least one, in particular exactly one, actuating arm which is mounted or can be mounted on the main part at a first end so as to be pivotable about an axis of rotation. The actuating arm is or can be connected to the mounting device at a second end opposite the first end via at least one multi-joint mechanism, and the multi-joint mechanism has at least three, preferably at least four, particularly preferably exactly four, joints each having an axis of rotation.

A door presenting device for a motor vehicle door element having an electric drive unit and an actuating means, wherein the actuating means can be adjusted by means of the drive unit and a gear mechanism arranged between the actuating means and the drive unit, with the result that a movement of the door element can be enabled, and further having a locking means. The door element can be maintained in position by means of the locking means and the locking means can be electrically actuated, namely indirectly, preferably manually, actuated.

The present invention relates to a door operator (1) and to a method performed in a door operator system (100) comprising a door operator (1) connected to and arranged to move at least one door leaf (5) between an open and closed position, the door operator (1) comprising a control unit (3) configured to control the movement of the at least one door leaf (5), the method comprising: obtaining (S100), in a sleep mode of the door operator system (100), a sequence of input data in one or more components of the door operator (1) or the at least one door leaf (5), receiving (S110), in the control unit (3) of the door operator (1), said sequence of input data from the one or more components, and evaluating (S120) said sequence of input data and ranking (S130) the probability of that said sequence of input data corresponds to an intrusion attempt on the door operator system (100).

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.

A door opener includes a first side cover fixed to a mounting seat. A mode switching device is disposed on the first side cover and includes an anti-theft control module. A driving device is operatively connected to a door for moving the door. A control device is electrically connected to the mode switching device and the driving device. The control device includes a control panel for operating the driving device. The mode switching device is switchable to a wake-up mode only when the anti-theft control module is unlocked. The driving device is operable by the control panel only when the mode switching device is in the wake-up mode. An outer cover is coupled to the first side cover and covers an outer side of the driving device and an outer side of the control device. The control panel is exposed via a window of the outer cover to permit operation.

The invention relates to a fitting arrangement having a furniture connecting fitting, in particular a hatch holder, which can be used to attach a furniture hatch or a door can be to a cabinet body in a swiveling manner, wherein an interlock (200) and a bracket (300) are provided, which can be used to connect the furniture hatch in a form-fitting and/or form-locked manner to the furniture body in a closed position of a kinematic arrangement (30) of the furniture connecting fitting, wherein the kinematic arrangement (30) has levers and links, which can be used to move the furniture hatch or door from the closed position into an open position, wherein a spring element (38.2) is provided which, in the closed position of the kinematic arrangement (30), introduces a prestress into the kinematic arrangement (30) in the opening direction, and wherein the interlock (200) and the bracket (300) form a release mechanism, which can be used to release the connection between the interlock (200) and the bracket (300) in the closed position of the kinematic arrangement. Such a fitting arrangement can be used to effect a convenient opening of a door or hatch from the closed position.

The present disclosure relates to a door leaf formed of a flexible material, wherein the flexible material is resistant to puncture and resistant to tearing; and to a door system comprising the door leaf.
