Mechanical brake arrangement (400) for controlling the movement of one of the door leafs of a double door system. Door operator system (10) comprising a first door operator (11), a second door operator (12) and a mechanical brake arrangement (400).

An arrangement for closing an access member rotatable relative to a frame about a hinge axis, the arrangement comprising a primary element for fixation to either the frame or the access member; a secondary element for fixation to the other of the frame and the access member; a connection device arranged between the primary element and the secondary element and engaging the secondary element; and a force device comprising a drive element rotatable about a pivot axis and engaging the connection device, the force device being arranged to force rotation of the connection device relative to the primary element about the pivot axis, wherein a position of the force device relative to the primary element is adjustable after fixation of the primary element and the secondary element to adjust a distance between the pivot axis and the hinge axis. An access member system and a method are also provided.

Device for the closing and/or opening of a leaf, to be applied to a concealed hinge comprising two bodies articulated to each other through at least a pair of articulation arms and connectable respectively to a leaf and to a fixed structure, the device being intended to be associated with one of the two bodies of the hinge, the device including: a translating element engageable to/with an articulation arm of the hinge, at least one mobile group configured to cooperate with the translating element and which is mobile with respect to an element/structure which can be mechanically fixed to the hinge body to which the device is to be associated; elastic means acting on the mobile group to cause the movement of the mobile group and the translating element;
the translating element, the at least one mobile group and the elastic means are configured and reciprocally arranged.

A door pop-up system includes a check link, which is rotatably coupled to a body of a vehicle, and a pressure member, which is rotatably arranged inside a door. The check link has a tip portion to enter the inside of the door. The pressure member presses a tip of the check link in a movement direction of the check link in which the check link moves as the door in a closed position is actuated to be opened. The door in a closed position is actuated to be opened by rotation of the pressure member and pressing of the tip of the check link with the pressure member. The pressure member has a pressure surface at which the tip of the check link is pressed. The pressure surface has a restriction surface to restrict displacement of the check link in a height direction.

Telescopic assembly with locking device in retracted configuration A telescopic assembly (10) includes: a first (12) and a second (14) body; the second body comprising a rod capable of sliding into the first body between extended and retracted configurations; and a device (18) for locking in the retracted configuration. The locking device includes a ferrule (60) positioned on the rod, the ferrule comprising an internal stop (80) and the first tubular body comprising a counter-stop (34), capable of cooperating to lock the first tubular body and the ferrule. The ferrule is locked in translation relative to the second body (14) and rotatable around said second body, between an unlocked position, allowing the sliding of the second body into the first body (12), and a locked position retaining the second body in the retracted configuration.

An arrangement for closing an access member rotatable relative to a frame about a hinge axis, the arrangement comprising a primary element for fixation to either the frame or the access member; a secondary element for fixation to the other of the frame and the access member; a connection device arranged between the primary element and the secondary element and engaging the secondary element; and a force device comprising a drive element rotatable about a pivot axis and engaging the connection device, the force device being arranged to force rotation of the connection device relative to the primary element about the pivot axis, wherein a position of the force device relative to the primary element is adjustable after fixation of the primary element and the secondary element to adjust a distance between the pivot axis and the hinge axis. An access member system and a method are also provided.

A double locked safety door barrier is provided, which includes a door frame and a door leaf hinged inside the door frame. A switch housing is provided on the door leaf, an upper locking tongue and a lower locking tongue are respectively provided in the switch housing and at a bottom of the door leaf. An upper locking buckle and a lower locking buckle are provided on the door frame; an upper unlocking component and a lower unlocking component are respectively provided on the switch housing. The lower unlocking component is connected to the lower locking tongue through a connector and is provided with a two-way lock structure that can only be driven to be retracted by pressing the upper unlocking component after pressing the lower unlocking component. The two-way lock structure simplifies the user's operation process and increases the safety of a locker.
