Description

The present invention relates to a door handle set for conveying information to a user which is transmitted when a door belonging to the door handle set is opened or closed.

State of the art

Door handle sets have been known for a long time. Hardware that is usually used to open and close swing doors is called a door handle set. A door handle set has two door plates or escutcheons attached to the two sides of the door, as well as two door handles which are connected to a handle pin that passes through the door leaf. This trigger pin triggers a latch mechanism when actuated, by which the latch bolt is pulled back and the door is unlocked. The actuation of the door handle radially around the handle pin first moves the latch, the actuation of the door handle axially on the handle pin subsequently moves the door leaf or door leaf. Lever handles are the central operating element in opening and closing processes and are accordingly located in an ergonomically optimal position and centrally visible within the door view.

Arrangements for outputting information are known in the prior art which output the information in a visual, auditory and audio-visual manner.

From the EP 2 816 180 A2 A safety device for locking devices with a handle is known, wherein the handle can be freely rotated in the idle state and can be coupled to a locking member of the locking device in the open or closed state, comprising a braking and possibly blocking device which brakes and possibly blocks the rotary movement of the handle , wherein the braking device is designed as an eddy current brake.

The EP 0 785 324 A1 discloses a drive device for a lock, a lock cylinder or the like, in the form of a fitting plate with a drive shaft for transmitting a rotary movement to the lock or the lock cylinder, with a rotary handle for manual rotation of the output shaft and a geared motor for motorized rotation of the output shaft, the Geared motor is driven in rotation with the turning handle, so that a torque applied to the motor housing when it is actuated is transmitted to the drive shaft and that the rotatability of the motor housing can be blocked for motor rotation.

An object of the invention is to improve the state of the art. In particular, it is an object of the invention to provide a door handle set which passes on information to a user of the door handle set without the information being accessible to outsiders. Another object of the invention is to provide a lever handle set which improves the transfer of information which is related to opening or closing processes.

The task is solved by a lever handle set for conveying information to a user which is transmitted when a door belonging to the door handle set is opened or closed.

The door handle set has a doorknob for opening a lock latch of a door by the user, a receiving unit for receiving the information, a force setting device for setting a force for actuating the doorknob and a control and arithmetic unit for processing the received information and for controlling the force setting device. Here, the control and arithmetic unit is designed and set up in such a way that, depending on the information received on the force setting device, a force for actuating the doorknob is set if the user actuates the doorknob, so that in this case the user perceives a mechanical resistance of the doorknob proprioceptively can, whereby the received information is passed on to the user.

A door handle, also called a door handle or door handle, is usually an angled lever for opening and / or closing a door by hand. In the present case, the term door handle should also be understood to mean a doorknob which is actuated by a rotation.

Proprioception, proprioception, proprioceptive perception or depth sensitivity describes the perception of body movement and position in space or the position of individual body parts to one another. It is part of the interoception and differs from the surface sensitivity, especially the tactile or haptic perception. In particular, the power sense for proprioception is included, which provides information about the state of tension of muscles and tendons.

The force for actuating the doorknob can also be set such that a human user can no longer actuate the doorknob because the force to be applied is too great. Alternatively, the door can be locked. However, it is preferred that the resistance of the doorknob is increased and the doors are not locked, since an improvement in compliance with escape route concepts, for example in fire situations, can thus be achieved. Escape and rescue routes are therefore not impaired and can be used without restriction in an emergency.

One advantage of the door handle set is that when the door is actuated, a user of the door is proprioceptively perceived change in the pressure of the door handle information by the action performed, i.e. by operating the doorknob. The strength of the mechanical resistance is used to clearly and individually, i.e. without disclosing the information to outsiders to provide the user with information.

In the case of door handle sets of the prior art, the conveyance of information relating to the opening or closing process is visual or audio-visual by means of textual and symbolic warnings and warning tones, and a binary influence on the opening or closing process, e.g. by refusing access. This reduction to audio-visual textual and symbolic information and sounds creates serious problems in many application scenarios.

Information that is conveyed through strong visual and auditory stimuli is often not perceived optimally and is overlooked with increasing exposure or ignored or not optimally considered.

Frequently, a continuous request by notices and in particular refusal of access is perceived by a user as an external restriction of his personal freedom. A resulting negligent misconduct such as the active overriding of health and safety regulations, e.g. keeping doors open is observed as the main cause of accidents at work.

In addition, users who have impaired eyesight or hearing cannot or only to a very limited extent capture visual or auditory stimuli. This results in an avoidable accumulation of accidents at work that affect people with impaired vision or hearing.

Another advantage of the lever handle set is that it allows integration into existing door systems and IT infrastructures.

The door handle set can have a handle pin which is designed and set up such that when a user actuates the door handle, the handle pin is rotated about its longitudinal axis. This actuates the lock latch, which is colloquially called the snap, so that the door can be opened. This feature allows the lever handle set to be combined with existing systems.

In order to implement the force setting device in a simple manner, it can be implemented by an electromagnetic brake having a coil and a rotor, a current flow through the coil causing a frictional connection between the rotor and the coil. The coil is preferably applied centered on the shaft, in the present case the handle pin, with the flange on the door leaf. Furthermore, the rotor of the clutch is mounted on the pusher pin via a feather key connection and axially secured. The rotor of the clutch is thus connected to the door handle via the handle pin. The frictional connection of the rotor and coil thus results in a change in the torque to be applied for actuating the pawl.

An axis of the coil can be arranged coaxially with the longitudinal axis of the pusher pin, whereby a simple construction can be achieved, which at the same time achieves an optimal physical coupling.

In order to detect a user touching the door handle, the door handle set can have a capacitive sensor module which is electrically connected to the door handle. Since the return of the latch bolt and thus the door handle to the original position should preferably not be affected by the spring pressure due to the frictional engagement described, it is necessary in this case to produce this frictional engagement only when actuated by the user. For this purpose, the capacitance is continuously measured by the capacitive sensor on the jack, the capacitive sensor preferably being connected to the control and computing unit. If a touch has been identified by the user, the coil is switched on, which causes a frictional connection between the rotor and the coil. Processing of the sensor data and switching of the current flow through the coil is ensured by the control and computing unit, which can be implemented by a microcontroller.

The door handle set can also have a visual output module for outputting information. In this way, it is advantageously achieved that, in addition to the information which is conveyed to the user by actuating the latch with a different torque, the door handle set can convey at least one further visually recognizable information.

Here, the visual output module can be used to ensure, in addition to the proprioceptively perceived transmission of information, redundant or precise transmission of this information. In experimental tests with the lever handle set, it was recognized that the attention of users to a visual output module at the level of the door handle set is clearly supported by changing the pressure on the handle.

The visual output module is preferably attached to the sensor and is preferably ring-shaped.

In order to supplement the proprioceptively perceived information with a further sense perception, the door handle set can also have an auditory output module for outputting information.

The receiving unit can have a network interface. Such a, preferably standardized, interface in a simple manner ensures that information can be made available to the lever handle set. The network interface can be connected to the control and computing unit.

In order to easily implement the control and arithmetic unit with standard components, the control and arithmetic unit can have or consist of a microcontroller.

The information which is related to the opening or closing process of the door belonging to the lever handle set can be directly and / or indirectly related to an opening or closing process of the door.

In this case, indirect information is understood to mean information which has no current temporal connection with an area which is opened or closed by the present opening or closing process of the door. This information can e.g. Include warnings or warning signs regarding recommended or to be observed occupational safety measures in the developed area. There is no current chronological relationship here, as these warnings apply permanently and must be observed.

In the present case, immediate information is understood to mean information which is in a current temporal relationship with an area which is opened or closed by the present opening or closing process of the door. This can e.g. Provide information on access authorization, use of space and chemical or biological contamination of the area opened up by the opening or closing process. In contrast to an indirect connection with the opening or closing process, information directly related to the opening or closing process is intended to sensitize the user to the information communicated in a small time window around the current opening or closing process. The time window can range from a few milliseconds to months or years.

The information received by the receiving unit can come from local sources or from remote sources.

Here, information from local sources is understood to mean information which is sensed by sensors in one of the adjacent rooms or which originates from there. This includes, for example, image recognition systems, CO2 sensors, room air sensors, condition measurements of machines and devices, etc. Remote sources can include databases, programming interfaces to services such as calendars, and sensor-acquired information from areas that are not adjacent to the door. This also includes information about an opening status of a door other than the door of the present lever handle set.

A door with a lever handle set, which is located in the adjacent rooms, is therefore also considered to be a distant source.

The information received can have an opening angle of the door. Furthermore, the information received can also have opening angles from other doors which are equipped with the lever handle set presented here. This feature advantageously makes it possible for the force to be actuated to actuate the lever handle set to be dependent on other doors which are in a local, temporal or other connection with the present door. One possible application of this feature is e.g. a scenario in which behind a first open door, e.g. a fire door, a second door, e.g. also a fire door is arranged. If it is not intended that the first door is open, the lever handle set of the second door can be set so that only difficult passage is possible.

A scenario in which local information which is indirectly related to the opening or closing process is conveyed is an application in which compliance with self-determined occupational safety measures is supported. If a user disregards given occupational safety measures, the resistance of the doorknob is increased in order to sensitize the user to this fact individually and without disruption. Specifically, wearing protective clothing, e.g. Safety glasses, breathing apparatus, flame-retardant protective clothing etc., as a recommended occupational safety measure confirmed by an image recognition system and the resistance of the door handle modified accordingly. This resistance alerts the user to the fact that there is a lack of occupational safety and health, without restricting it when carrying out his action. Passing through the door is difficult, but there is no functional limitation of the door handle. The door can still be walked through.

Another scenario in which local information that is directly related to the opening or closing process is conveyed is an application in which the sensitization of visitors and staff to a possible contamination with multi-resistant pathogens (MRE) in inpatient medical facilities is achieved. A disinfection dispenser monitoring sensory disinfection processes is used here. Room users become two-stage for disinfection measures that have not taken place, e.g. initially proprioceptive and still auditory, as well as visually informed about contamination of the door handle.

Yet another application scenario in which remote information that is directly related to the opening or closing process is conveyed is the case in which room users are informed about room occupancies of meeting rooms. Here, information is obtained from a remote calendar or room booking system. If there is room occupancy for a room, the resistance of the doorknob is increased, the entrant is informed about the use of the room and a non-disruptive, inconspicuous opening or closing process is supported by the user.
