Definitions

  • the present invention relates to a door closing device for a door leaf of a swing door and such a swing door with such a door closing device.
  • swing doors are equipped with door locking devices.
  • a swing door is movable between a closed position and at least one opening position over an opening area. In the closed position, the swing door closes the door opening. In the open position, the swing door is open so that a person can move through the door opening.
  • a known swing door can be movable on one side or on both sides in a second opening position.
  • mechanical door closing devices are known. These are usually equipped with a spring device which spans when opening the door in the open position. This means that during the opening movement from the closed position to the open position, the exciting spring must be overcome with regard to the increasing spring force. The corresponding torque situation for the swing door usually runs linear. Depending on which shape and type of swing door is present, different biases or different spring characteristics for the door closing device may be important. Therefore, it is also known to make corresponding spring devices adjustable, so that the spring can be used with different bias values.
  • a disadvantage of known door closing devices is that they have only a low flexibility with regard to their possible use.
  • an adjustment basically offers a variation of the bias of a spring device for closing or in terms of the closing force for the swing door, but here is a more or less linear force situation given. This means that when increasing a preload force for a necessary larger closing torque with a larger closing force automatically a more difficult operability of the swing door is accompanied.
  • the bias voltage for the closing force of the corresponding spring device is increased, accordingly more force must be expended in order to move the swing door from the closed position in the direction of the open position already at the beginning of the opening movement.
  • z In particular, in use, which require a smooth operation, z. As in retirement homes, daycare or in the field of housing for the disabled, such a difficult movement is undesirable or even prohibited in principle.
  • Known door closing devices with adjustable spring devices are therefore not applicable in such sensitive areas, which suffers their versatility.
  • a possible use with easier opening operation is achieved.
  • a door closing device designed for a door leaf of a swing door, which is movably mounted between a closed position and at least one opening position over an opening area.
  • the door closing device has a torque connection for the torque-transmitting connection with the door leaf.
  • a closing spring is provided, which acts on the door leaf via the torque connection in the direction of the closed position with a closing force.
  • an opening spring is provided, which acts on the door leaf via the torque connection in the direction of the opening position with an opening force.
  • the opening spring has an adjusting device for adjusting the opening force.
  • the combination of two springs is provided according to the invention. These apply forces which act in different directions of action via the torque connection on the door leaf.
  • the closing spring thus tries to move the door leaf into the closed position.
  • the opening spring serves to push the door leaf into the open position with its opening force. It is irrelevant at first in which orientation the respective spring is located. It is crucial that z.
  • an opening spring and a closing spring are basically spring devices to understand that have an elastic deformability and accordingly along a spring characteristic deformability. It may be z. B. act to coil springs. However, other elastic materials for the formation of the respective spring, so the closing spring and the opening spring, in the context of the present invention are possible.
  • the two opening springs act against one another, so that the force situation or the torque situation on the door leaf is established by the combination of the two spring forces.
  • the opening force thereby supports the opening movement, in particular in the front region of the opening region, ie when the door leaf has just left or left the closed position.
  • the opening force decreases during the movement from the closed position to the open position and reaches in particular at the latest when the open position is reached, the value zero.
  • the closing spring serves to make movement from the closed position into the open position more difficult.
  • the closing force increases by increasing the bias in the closing spring from the closed position to the open position.
  • the two springs work in opposite directions, so that despite a desired bias with high efficiency in the open position by the opening spring takes place a support in the front opening area in the closed position.
  • the support by means of the opening force through the opening spring is despite the high Closing force also a smooth operation when leaving the closed position possible, since there is a significantly changed torque situation on the door leaf. Accordingly, the closing torque is reduced by the opening torque provided by the opening force of the opening spring. In this way, a combination is achieved by ease of use for leaving the closed position and at the same time high restoring force by the closing spring in the open position.
  • a door closing device can also be used in sensitive applications with smooth operation. Nevertheless, it is possible to equip even heavy door leaves with such a door closing device, so so still a high biasing force for the opening position can be selected by means of the closing spring. In the rear opening area is thus the usual and above all also desired opening damping or return characteristic for the door leaf.
  • the adjustment of the opening spring now serves to adjust the ease of opening support and thus the door panel.
  • the opening spring and its adjustment device are used to provide an adapted to the particular application situation opening characteristic. If the opening spring is preloaded, the opening force in the closed position is strengthened on the one hand, and the distance over which the opening spring actually acts on the door leaf is increased on the other hand. If the opening spring is reduced with respect to the opening force by means of the adjusting device or even left without any bias, this opening spring is substantially turned off, so that the opening support now no longer takes place. Any setting can now be made on the opening spring via the adjusting device, so that a particularly flexible application is possible by selecting the corresponding preload of the opening spring the door closing device is possible.
  • the door closing device according to the invention can be found by using the opening spring and appropriate adjustment to the setting and for ease of use in sensitive situations use. Due to the increased flexibility, a reduction in costs can be achieved by increasing the number of individual components.
  • the torque connection has a coupling device which distributes the torque transmission from the door leaf to the opening spring and the closing spring.
  • This coupling device can, for. B. be designed as a lever kinematics, so that a rotational movement of the door is distributed over one or more levers of the torque connection to the opening spring.
  • These may be external levers, z. B. to a Zweigelenksystem act, which extend between the door frame and the door closing device on the door leaf.
  • the coupling device may comprise internal levers which are formed between a rotatable sleeve and the corresponding springs. Further, it is possible that the coupling device, for. B. achieved via an eccentric disc, a correlation movement between the springs.
  • an eccentric disc can be supported on contour sections, so that the contour sections are pressed in a predefined direction through the eccentric disc by rotation of the eccentric disc during the opening movement of the door.
  • the opening spring and the closing spring each have a spring rotation axis, in particular designed as a helical spring and the spring rotation axes are aligned parallel or substantially parallel.
  • the opening spring and the closing spring are thus parallel to each other, so that in particular the smallest possible distance between the opening spring and the closing spring can be specified. This reduces the space required for the door closing device. Also, the cost of materials for a surrounding the opening spring and the closing spring housing is reduced in this way. Not least, in this way, a simpler deflection of the opening force and the closing force on the torque connection, z. B. by a coupling device possible. Accordingly, corresponding lever connections preferably also extend in parallel from the torque connection to the respective spring.
  • the opening spring has an area of action which, starting from the closed position, is smaller than the effective area of the closing spring.
  • An area of action is to be understood as the area in which the opening force, which acts on the door leaf via the torque connection, is greater than zero. In this area of action, therefore, the opening force is transmitted to the door leaf of the opening spring.
  • the closing spring preferably acts over the entire opening area, ie completely over the opening movement between the closed position and the open position.
  • the opening spring is designed, in particular, at least in the front opening area, that is to say starting from the closed position.
  • the opening force is no longer crucial and can be omitted accordingly.
  • the opening spring can be made smaller and thus cheaper and more compact. After leaving the front opening area thus acts only the closing spring with its closing force, so that the known, a particular on the closing spring also adjustable, force characteristic can be provided for the rear opening area.
  • the adjusting device is designed for setting a minimum preload of the opening force of the opening spring, so that it is out of action over the entire opening area of the door leaf.
  • a minimum bias of the opening force is in particular a bias that does not exist, so an unstressed opening spring. This is already applied in the closed position of the door leaf with an opening force of zero, so that no support of the opening movement takes place in the front opening area.
  • This door closing device is thus used as a classic door closer, and will find particular use in normal applications.
  • the setting device thus also allows the classic application possibility, without affecting the basic inventive support option in the front opening area.
  • the adjusting device is designed for setting the opening force of the opening spring with a maximum bias, so that the opening spring acts with its opening force over the entire or substantially entire opening area.
  • the two limits defined the range of action of the opening spring.
  • the smooth operation of the operation of the door closing device can be varied as desired and, in particular, also be adjustable from a complete mechanical switching off of the opening spring to the maximum effect over the entire opening range.
  • the flexibility of the door closing device is further improved by the adjusting device formed in this way.
  • a further advantage may be provided when a damping device according to the invention for damping the movement of the door leaf in the opening region is provided.
  • This is in particular a hydraulically acting damping device.
  • This can, for. B. be formed as part of the torque connection. This ensures that, in particular during the automated mechanical closing movement of the door leaf, no too rapid release of the spring energy of the closing spring is carried out. A heavy slamming with appropriate risk to the person using is further reduced by the damping device.
  • the adjustment device has a handling interface for handling the adjustment of the opening force of the opening spring.
  • the handling interface may comprise a knurled screw, which is preferably designed for a tool-free adjustment of the opening force of the opening spring.
  • an attack section as a handling interface for a tool eg. B. one Screwdrivers, an Allen key or an open-end wrench are possible in the context of the present invention.
  • a swing door having a door leaf and a bearing device, by means of which a movement of the door leaf over an opening region between a closed position and at least one open position can be carried out.
  • a swing door according to the invention is characterized in that a door closing device is provided, which is connected via a torque connection to transmit torque to the door leaf.
  • the door closing device is designed according to the invention, so that the swing door brings about the same advantages as have been explained in detail with reference to a door closing device according to the invention.
  • the storage device can be formed arbitrarily and in particular independently of the door closing device.
  • a swing door according to the invention can be further developed in that the door leaf, the storage device and the door closing device are designed for a double-sided opening with a second opening position.
  • the swing door can therefore be opened inwards and outwards, so that there are two oppositely oriented opening positions. If the closed position z. B. defined by a 0 ° -Auslenkung the bearing device, the two opening positions z. B. defined by about -90 ° and about + 90 °. In particular, accordingly, the two opening positions are arranged symmetrically to the closed position on both sides.

In the FIGS. 2a and 2b it is the minimum bias of the opening spring 40, so there is no bias at all. Accordingly, the opening spring 40 does not introduce an opening force OK into the torque port 20 at this setting.
