Description

The invention relates to a door fitting system and a door handle and a cleaning unit for such a door fitting system.

Doors are usually opened and closed manually using door handles such as door handles or knobs. Viruses, bacteria and/or germs can settle on the door handle through contact, which in turn can then be transmitted to other people through contact with them. Especially in high-traffic and/or health-sensitive areas, such as hospitals, door handles should therefore be cleaned or disinfected regularly. Such cleaning or disinfection is carried out manually and is therefore associated with a corresponding amount of effort. In addition, it cannot be guaranteed that cleaning will be carried out after each contact. Corresponding transmission risks can therefore not be ruled out.

In view of the above statements, it is therefore the object of the present invention to provide a door fitting system and a door handle and a cleaning unit for such a door fitting system in order to enable the door handle to be cleaned or disinfected by the door fitting system.

The object is achieved by a door fitting system and a door handle and a cleaning unit for such a door fitting system according to the independent claims. Advantageous developments of the invention are contained in the dependent claims.

According to the invention, a door fitting system has a door handle for actuating a door latch and a cleaning unit, the door fitting system being designed in such a way that a relative movement between the cleaning unit and the door handle can be carried out to clean the door handle.

The door handle is thus guided past the cleaning unit or vice versa via the relative movement, so that the door handle can be cleaned directly. Separate cleaning is therefore no longer necessary.

In one embodiment, the door handle is configured to be moveable through a door in a substantially horizontal direction for relative movement with respect to on-demand installation.

Accordingly, the relative movement between the cleaning unit and the door handle can take place via the movement of the door handle through the door. Due to the provided essentially horizontal direction of movement when the door handle is installed as required, the direction of movement for cleaning the door handle can differ in particular from the direction of actuation for actuation of the door bolt. The separation of the directions favors both the handling and the constructive structure of the door fitting system. The term "essentially" refers to the fact that the direction of movement of the door handle for cleaning can also deviate from a horizontal direction of movement, but the basic orientation of the movement can be seen as essentially horizontal, in contrast to an essentially vertical direction of actuation.

The movement of the door handle through the door enables installation space that is independent of the respective door. The door therefore does not have to have a minimum thickness to accommodate the door fitting system. Correspondingly, such door fitting systems can also be used or retrofitted in many ways in a simple manner.

According to a further development, the door handle is designed to be rotationally symmetrical with respect to an axis that is perpendicular to a direction of movement provided for cleaning.

Thus, the door handle can be turned through the door by means of a rotary movement about the vertical axis provided for the direction of movement intended for cleaning.

This is preferably done in that the door handle is designed as a ring-shaped pawl, so that the pawl or the handle is rotated through the door.

Alternatively, however, the door handle can perform a translational movement in order to be moved through the door. In such a case, the door handle does not have to be rotationally symmetrical.

In one embodiment, the door fitting system has a drive, via which the relative movement can be carried out.

An independent self-cleaning of the door handle can be carried out via the drive. It is therefore not necessary to carry out the relative movement manually, so that there is no renewed risk of contamination when the door handle is cleaned.

In particular, the door fitting system is designed in such a way that the door handle rotates at least 180°, preferably 360°, with respect to the drive a vertical axis provided for the cleaning direction of movement is rotatable.

By rotating through at least 180°, at least half of the door handle can also be guided past the cleaning unit in the rotationally symmetrical design of the door handle. If the axis of rotation for the relative movement and the cleaning unit are essentially in the area of the door plane, a completely cleaned door handle section is available again at least on one side of the door for cleaning that corresponds to the drive path. If the cleaning unit spans the entire passage area of the door handle or if several cleaning units are arranged accordingly, complete cleaning can also be carried out on both sides by turning 180°.

With a rotation of 360°, a smaller cleaning unit and/or just one cleaning unit can be sufficient to clean all contact-relevant areas of the door handle in one rotation.

The rotation can be implemented, for example, via a simple motor in connection with a rubber friction wheel.

According to a development, the drive can carry out the relative movement bidirectionally.

In this way, for example, a door handle section can be repeatedly cleaned without having to carry out a complete revolving movement.

In one embodiment, the drive is designed as an electric motor and the door handle is designed as a stator of the electric motor.

The door handle can thus be moved directly between the drive and the door handle without any further transmission components. This also enables a compact structure of the door fitting system, for example.

In particular, the door fitting system comprises at least one door plate on which the door handle is provided such that the door plate can be moved when the door handle is actuated to open the door, and/or on which the cleaning unit can be arranged.

Due to the fact that the door plate can also be moved when the door handle is actuated, a corresponding door handle guide can be omitted. A door handle that is designed to be rotationally symmetrical in the direction of movement for cleaning and that extends through the door can thus, for example, be rotated about an axis of rotation that is perpendicular to its axis of symmetry in order to actuate the door latch. The door sign turns with it. The axis of rotation of the door sign is in particular in the center of the door sign and concentric with the axis of rotation of the door handle.

The cleaning unit can be arranged on the door plate in conjunction with the mobility of the door plate or also independently thereof. In the case of door signs provided on both sides of the door, both door signs can each have a cleaning unit. By arranging the cleaning unit on the door sign, a compact design of the door fitting system is possible. In addition, better accessibility to the cleaning unit can result.

According to one embodiment, the cleaning unit and/or the protruding door plate has an operating display, from which an operating status can be read.

The operating display can, for example, be an indicator that cleaning has taken place. For example, the cleaning unit and/or the door sign can have a light that lights up after cleaning has taken place without further actuation of the door handle. However, the operating display can also alternatively or additionally indicate an operability of the cleaning unit and/or the drive.

In a further development, at least one resource level can be read from the status display.

The resource level includes, for example, a fill level indicator for a cleaning agent in the cleaning unit and/or a battery level indicator for driving the door handle.

In one embodiment, the door handle can be moved in an actuation direction to actuate the door bolt and the relative movement for cleaning is triggered after the actuation process of the door handle has ended to open the door bolt.

The cleaning process is thus triggered automatically after the door handle is operated to open the door bolt. This can be implemented, for example, via a contact switch that closes when the door handle is in an initial position, ie without being actuated. The closing of the contact can then start the cleaning process once per closing process.

Alternatively or additionally, a cleaning process can also be triggered independently of an actuation of the door handle to open the door bolt. A switch or other trigger, such as a capacitive or optical sensor, can be provided for this purpose. So it's a nut It is also possible to initiate a precautionary cleaning process without operating the door handle.

In particular, the door fitting system is configured in such a way that kinetic energy for the relative movement for cleaning can be stored by actuating the door handle.

For example, the movement of the door handle for cleaning can be converted directly from an actuation movement to open the door latch. The movement triggered thereby is preferably delayed, so that the cleaning process only begins when contact with the door handle can no longer be assumed. Alternatively or additionally, the kinetic energy can also be stored by driving a dynamo or exciting piezo elements for energy supply. The stored kinetic energy can be fed to the drive for the relative movement. The drive can thus be operated independently or at least in support of reducing the consumption of other energy sources.

In a further aspect, the invention relates to a door handle for a protruding door fitting system, the door handle being ring-shaped.

The ring-shaped design of the door handle allows the door handle to be easily guided through the door for cleaning while at the same time being easy to handle. In addition, the cleaning surface of the door handle is reduced compared to a full-surface door handle. In this way, the size and installation space of the cleaning unit can also be reduced.

In one embodiment, the door handle includes at least one magnet, preferably a permanent magnet.

The door handle can be used via the at least one magnet as a rotor of an electric motor for driving the door handle, as has already been addressed above. Permanent magnets offer a simple and inexpensive implementation variant. For example, at least one magnet can be installed in the ring body of the door handle or this can be formed at least in sections from one or more magnets.

In addition, the invention relates to a cleaning unit for a protruding door fitting system, the cleaning unit having an operating fluid reservoir which can be removed and/or filled from the outside when installed in a door.

The resource store can thus be exchanged, checked and/or filled with resources, for example without removing the cleaning unit or the entire door fitting system or at least parts thereof.

• 2 zeigt eine schematische Draufsicht in einer Ebene senkrecht zur horizontalen Querschnittsebene des Türbeschlagsystems gemäß 1.

The invention is explained in more detail below on the basis of an embodiment with reference to the accompanying figures. The figures show in detail:

• 1 shows a schematic cross-sectional view of a door hardware system according to an exemplary embodiment of the invention in a horizontal cross-sectional plane.
• 2 shows a schematic plan view in a plane perpendicular to the horizontal cross-sectional plane of the door fitting system according to FIG 1 .

1 shows a schematic cross-sectional view of a door fitting system 1 in a horizontal cross-sectional plane when the door fitting system 1 is installed in a door 5. The door fitting system 1 in the present embodiment has a ring-shaped door handle 2, two door plates 3 each arranged on one side of the door, and a cleaning unit 4. The door bolt 6 can be locked via the door handle 2 when the door handle is actuated in the in 2 actuation direction B shown can be actuated. The axis of symmetry of the rotationally symmetrical door handle 2 lies in the middle of the door 5 during installation. The door handle 2 can be rotated about its axis of symmetry in a direction of movement A for cleaning by means of a drive 31 . The axis of symmetry of the door handle 2 is thus concentric with the axis of rotation for the movement for cleaning.

The cleaning unit 4 is arranged here as an example on one of the door plates 3 and covers the lead-through sections of the door handle 2 on both sides. Due to the overlap on both sides, the door handle 2 can also be cleaned simultaneously on almost opposite door handle sections. Accordingly, the rotary movement can be limited to about 180° for a complete cleaning process. Even if the cleaning unit 4 only shows cleaning on one side in the illustration, the cleaning unit itself can also act on the door handle 2 from the opposite side, so that cleaning takes place on both sides. Alternatively, a further cleaning unit located opposite can be provided.

2 shows that in 1 illustrated door hardware system 1 in a plan view of the door 5 perpendicular to the cross-sectional view. The door handle 2 is connected to the respective door plates 3 on both sides of the door 5 . The rotary movement of the door handle 2 for actuating the door bolt 6 in the actuating direction B takes place about an axis of rotation located in the center of the door plate 3 . The arranged on the door sign 3 designated cleaning unit 4 is moved along with it. In the 2 The horizontal position of the door handle shown represents an exemplary starting position or resting position of the door handle 2. If the door handle 2 is now moved out of this starting position in the operating direction B and then returns to this position, a cleaning process is automatically initiated. For this purpose, a contact switch (not shown) is provided, for example, which is closed after moving back into the starting position. The drive 31 then controls the rotational movement of the door handle 2 about the axis of rotation, so that the door handle is moved in the direction of movement A for cleaning. All the surfaces of the door handle 2 facing the cleaning unit 4 are cleaned by the rotary movement in the horizontal plane here by at least 180°. In addition to the automatic cleaning of the door handle 2 after the end of an actuation process, cleaning can also be initiated alternatively or additionally via a corresponding trigger, such as a switch button or a capacitive or optical sensor.

The movement of the door handle 2 in the direction of actuation or back to the starting position can not only cause the cleaning process, but can also be used to generate energy for the drive 31 . For example, a dynamo of the drive 31 can be coupled to the movement in the actuation direction B for energy storage. Actuation can also stimulate corresponding piezo elements.

The door sign 3 or the cleaning unit 4 arranged thereon also has an operating display 41 . In the illustrated embodiment, the status display 41 shows a resource level 41a, here the fill level of a cleaning agent in the cleaning unit 4. Alternatively or additionally, the status display 41 can also show a battery level for the drive or a cleaning status. Operating status 41a corresponds to in 2 to the contents of a resource store 42 of the cleaning unit 4. In the embodiment shown, the resource store 42 is accessible from the outside and can therefore be exchanged or filled without further expansion measures.

The invention is not limited to the embodiment described. In particular, the use of the door fitting system according to the invention also extends to furniture doors. The term "door plate" also includes door rosettes. Even if a specific design variant is aimed at rotationally symmetrical door handles in connection with a rotary movement, asymmetrical door handles can also be used. These then perform a translatory movement through the door for cleaning.
