Description

Technical field The present invention relates to an automatic door assistance system for opening and moving a door, in particular interior doors in residential or office buildings. The invention relates in particular to a floor-standing electromechanical device that can automatically open a door and close it again after a defined time or move it into a defined position, wherein the activation of the system is carried out by the detection of an authorized wireless identification transmitter in the vicinity of the door. State of the art Various systems are known from the state of the art that enable the automated opening or closing of doors. This includes, in particular, automatic door operators and door closing systems, which are typically installed on the door leaf, door frame, or in the building structure. Such systems generally require permanent installation and structural modifications to the door, door frame, or wall structure. Furthermore, systems are known in which doors can be operated by electronic authentication methods, for example, by wireless identification systems. However, with these systems, only the door lock is usually unlocked, while the actual movement of the door leaf is still performed manually by a user or by separate, permanently installed door operators. Furthermore, simple mechanical aids such as doorstops or holding devices are known to prevent a door from closing unintentionally or to secure a specific door position. However, such devices do not allow for automated movement of the door leaf. The known systems are therefore either permanently installed door drive systems or solutions that only allow unlocking of a door lock without providing automatic movement of the door leaf to a defined position. Object of the invention The object of the present invention is to provide a door assistance system that can automatically open a door and move it into a defined position without requiring any structural changes to the door or door frame and without fixed installation on the door or the building structure. Furthermore, the system should enable contactless operation and, in particular, provide automatic door opening based on the proximity detection of an authorized identification transmitter. Furthermore, the system should be easy to retrofit and can be used on different doors without any structural changes to the door or door frame. Description of the invention This task is solved by a door assistance system with the features of claim 1. The door assistance system comprises a floor-standing device (7) that can be positioned on the floor, with a housing (4), an electronic control, a radio detection device for detecting an authorized wireless identification transmitter, and an electromechanical drive (2) for moving the device. The device is designed to be positioned on the floor (7) directly next to the door leaf (1) in the area of the lock side of the door. The device is located in the immediate vicinity of the door rebate area or an edge area of the door leaf. The device includes a mechanical coupling device (5) which engages the door leaf (1), in particular engages under the door leaf or engages an edge area of the door leaf, and which establishes a mechanical connection between the device and the door leaf. The electromechanical drive (2) drives an axle on which at least one wheel (3) is arranged, enabling the device to move along the ground (7). This movement transmits a force to the door leaf (1) via the mechanical coupling device (5), thereby generating an opening or closing movement of the door. A frictional connection can be established between the mechanical coupling device (5) and the door leaf (1). A raising and protective element (6) shall be provided which prevents the coupling device from slipping and at the same time avoids damage to the door leaf. The element (6) can in particular be designed as an elastic or adhesion-enhancing contact material and can be provided on the mechanical coupling device (5), on the door leaf (1) or on both contact surfaces. The door assistance system is activated automatically by detecting an authorized wireless identification device in the vicinity of the door, provided that the identification device has previously been registered with the system or otherwise authorized. For this purpose, the system features a radio frequency identification device designed to detect such an identification transmitter within a predefined detection range. If an authorized identification transmitter is detected within this range, the door is automatically triggered to open. The detection range is preferably designed as a short-range area. The door can be triggered to close after a defined time interval, after the identification transmitter is no longer detected, or by a combination of both conditions, thereby closing the door again or moving it to a defined position or holding position. The identification of the identifier can be achieved in particular via a Bluet
