Description

TECHNICAL AREA

The present invention relates to a seal unit for a sillless door for sealing a gap between a door leaf and a floor. The sealing unit preferably comprises a lowerable door seal.

STATE OF THE ART

Door seals for sealing a lower end face of a thresholdless door are known. They should prevent light transmission and also provide sound insulation. Depending on the embodiment, an air passage should be avoided. Furthermore, door seals for exterior doors are known, which protect against driving rain and wind.

Lowerable door seals have a sealing strip with an elastomeric sealing profile, which is lowered automatically when the door leaf is closed and automatically raised again when the door leaf is opened. The release is preferably carried out purely mechanically by a protruding release button: The provision of the sealing strip in the raised basic position is usually achieved with return springs. Such Absenkdichtungen are known for years and, for example, in EP 0 338 974 as in DE 19 516 530 . EP 0 509 961 . DE 3 526 720 . DE 3 418 438 and DE 3 427 938 described.

The stroke of the sealing strip, the spring pressure and the nature of the surface to be sealed significantly affect the quality of the sealing effect. The hub is usually set during assembly, but not or rarely checked again later by the resident of the building.

The force applied to trigger the seal affects worse Setting the seal the closing behavior of the door. This aspect is usually observed only when mounting the door.

However, these settings may change over time for a variety of reasons. Furthermore, depending on the age of the seal greases may be compressed or the seal may be dirty, so that the triggering and / or the raising and lowering no longer be optimal. Lowering seals should also be subjected to maintenance from time to time in order to maintain their optimum function.

Furthermore, it is not always optimal for the room climate that a seal is lowered, although the door is closed. For example, in this case, a ventilation of the interior would have to be put into operation.

All these aspects have been little or only sporadically respected.

PRESENTATION OF THE INVENTION

It is therefore an object of the invention to provide a sealing unit which allows optimum use of a lowerable door seal.

This object is achieved by a sealing unit having the features of patent claim 1.

The sealing unit has at least one means for detecting a property or a state of the sealing unit, wherein information about this detected property or this detected condition can be displayed in the sealing unit or transmitted to a reading device.

The sealing unit thus allows monitoring of their condition or their properties. Depending on the embodiment, a regular maintenance is unnecessary by the sealing unit automatically makes itself felt when maintenance is necessary.

Depending on the embodiment, for example, one or more of the following properties and conditions can be detected or monitored, in particular in the lowered state of the sealing strip: the contact pressure on the ground; the tightness against water; the air outlet; the light transmission (e.g., in Minergie® solutions); the force required to trigger the seal; the time required for the reduction and / or increase; the total number of elevations and depressions of the sealing strip; the number of increases and decreases as a function of time; the age of the seal unit; the position of the sealing strip, i. it is lowered or raised; the degree of bending of the bending springs of the lowering mechanism; the displacement of the slider of the lowering mechanism; the displacement of the release button of the triggering device; a front-side contact pressure of the sealing strip; the temperature of the sealing strip; the force distribution along the sealing strip.

The at least one means is a corresponding sensor, transducer or counter or another means suitable for detection, depending on the nature of the property to be monitored or monitored or the state to be monitored or monitored. Preferably, the at least one means is at least one of the following units: contact pressure sensor, force sensor, humidity sensor, hydrosensor, air pressure sensor, stroke counter, light sensor, service life counter.

It is also possible to use several such agents together. The collected information can be individually edited or combined with each other and synthesized from it, which can be used by a user or a controller.

Preferably, the information obtained can be transmitted by means of near field communication (NFC = near field communication) and / or by means of Bluetooth or by means of similar types of communication to external devices or controllers. This eliminates a physical data connection from the sealing unit or the door wing to other building areas. In particular, the information can be sent by means of such communication techniques, in particular by means of NFC, to a smart device such as, for example Transfer mobile phone. This facilitates the commissioning of the seal, as set values, such as the correct choice of the stroke, which has a significant influence on the contact pressure, thus can be easily checked. Another important advantage is that the maintenance of the sealing unit is facilitated. On the one hand, it is easy to find out whether or how often the sealing strip has been lowered and how large the suspected wear of individual components is. Furthermore, it can also be determined immediately whether the functioning of the sealing unit is impaired, for example, whether the contact pressure no longer meets the requirements or whether, over time, passages have formed through which, for example, light or sound can pass. For example, it can also be determined whether a lubricating or lubricating grease has compressed and whether parts no longer move sufficiently smoothly or if parts of the seal are so dirty that the movement of individual parts is impeded.

As an alternative or in addition to the wireless transmission of information, it is also possible to attach at least one plug connection in the sealing unit in order to feed in and / or read out data.

In one embodiment, the at least one means is a passive data transmission element which only transmits the information upon request. In other embodiments, it is an active data transmission element, which sends an error message to an external receiver, for example by means of an app to the mobile phone of the homeowner or maintenance technician, for example, in the presence of a malfunction or failure to achieve a desired value.

The sensors can also be mounted on or in the housing rail, on or in the release button, on or in the lowering mechanism, on a fastening means used to attach the sealing unit to the door leaf, or at other suitable locations.

In one embodiment, the sealing unit has a stationary module to be arranged on the floor or in the door frame, which comprises at least one of the at least one means. Depending on the embodiment, the module alternatively or additionally has a reading unit and / or a display unit.

The sealing strip is preferably lowered automatically when closing the door leaf and can be raised automatically when opening the door leaf. Additionally or alternatively, elements may be present to operate the sealing strip manually or by motor independently of the position of the door leaf.

In a preferred embodiment, the triggering of the automatic lifting operation and lowering operation takes place mechanically. Additionally or alternatively, an electric motor is provided for automatically lowering and raising the sealing strip.

In a simple embodiment, the sealing unit indicates the achievement of a desired value or the non-fulfillment of a desired value optically. For example, a color change may take place. Alternatively or additionally, such information within the sealing unit can lead to the further actuation of the sealing strip being blocked. Depending on the embodiment, mechanical or electronic means are used for this purpose.

In preferred embodiments, the at least one means comprises a transmission means for transmitting the information. As a result, the information can be passed on to automatic or semi-automatic control systems and / or reported to interested parties.

In one embodiment, a reading device is present, which allows the homeowner and / or a maintenance fitter to query without disassembly of the sealing unit, the information on the condition, age and functional behavior of the seal and to make decisions on further action based on this information. This information can preferably be sent to readers such as a cell phone or a mobile phone Send another smart device, for example with an app.

A service module according to the invention for processing information of the sealing unit compares the information with desired values and signals the information deviating from the desired values. The service module may be a software program in a computing device, a device designed specifically for that application, an app for a smart device, or the like. The service module can be integrated in the sealing unit itself, in particular it can be arranged on or in the housing rail of the sealing unit or externally to the sealing unit, for example in the door frame. In other embodiments, the service module is a unit separate from the seal unit.

A sealing unit control system according to the invention for processing information of the sealing unit controls the sealing unit in accordance with the information and / or signals information differing from setpoint values. For example, the controller can lower a motor-driven sealing strip further, if the contact pressure on the ground has not reached a target value or it can raise the sealing strip slightly, should the contact pressure be too high. Depending on the embodiment, the control can also increase or decrease a lateral seal if the contact pressure in this direction does not correspond to the desired value. In addition or instead of the contact pressure, the light, water or air passage can also be used as the authoritative property for this purpose.

Preferably, the control system controls at least one further door unit, wherein the control system controls at least one of the at least one further door unit in accordance with the information. For example, the door may be provided with an anti-burglar or another lowering seal, which is lowered or raised in accordance with the information received from the controller.

The control system can be integrated in the sealing unit itself, in particular it can be arranged on or in the housing rail of the sealing unit or externally to the sealing unit, for example the door frame. In other Embodiments, the control system is a separate unit to the seal unit.

A building control system according to the invention for processing information of the sealing unit controls further units of the building in accordance with the information obtained. For example, a ventilation and / or air conditioning can be switched on or off, depending on whether the door is closed or opened.

Further embodiments are given in the dependent claims.

DESCRIPTION OF PREFERRED EMBODIMENTS

In the FIGS. 1 to 3 a sealing unit according to the invention is shown. It has a lowering seal of known type, which is provided with at least one means for detecting a property or a state of the sealing unit. The illustrated drop seal is to be understood as an example. It is also possible to provide other known lowering seals with inventive means for detecting a property or a condition of the sealing unit.

The lowering seal has a housing rail 1 which can be fastened to a door leaf T of a door. In this example, the door leaf T at its lower end face a groove N, in which the housing rail 1 is received and fixed to the front side, each with a mounting bracket 4 on the front side of the door leaf. The housing rail 1 can also be fastened laterally to the door leaf T or flush with the lower end side of the door leaf T. Furthermore, the lowering seal can also be attached to the upper end face of the door leaf and sealed to the ceiling. The term "floor" is therefore to be understood broader in this text, so that it includes at least the ceiling or other stationary or movable surfaces opposite the door leaf.

In the housing rail 1, a sealing strip is held, which is raised and lowered relative to the housing rail 1. The sealing strip comprises in this example a carrier rail 2, which, like the housing rail 1, is preferably made of a metal, in particular of aluminum. The sealing strip further comprises a one-piece or multi-piece elastomeric sealing profile 3, which is preferably made of silicone or rubber. The sealing strip preferably extends approximately over the entire length of the housing rail 1. The sealing strip, more precisely the support rail 2, is connected to the housing rail 1 via a lowering mechanism.

The lowering mechanism preferably has one or more leaf springs 6, arranged one behind the other in the longitudinal direction, which are connected at a first end to the housing rail 2, at a second end to a slide 7 displaceable in the longitudinal direction and in a central region to the support rail 2. This is in FIG. 2 recognizable. The slider 7 is connected to a release button 5, which the housing rail 1 laterally or, as shown here, protruding frontally. When pressure on the release button 5 from the outside, the sealing strip is lowered, without pressure, the sealing strip is raised again. The pressure on the release button 5 takes place when the door T is closed and the trigger button 5 is present on the door frame. If the door T open again, the release button 5 can assume its original projecting position and the sealing strip is raised thanks to the leaf springs 6 again. In other embodiments, the seal may alternatively be tensioned trigger. Such mechanisms are known in the art.

The FIG. 2 shows the release button 5 in partially depressed position and the sealing strip in partially lowered position. FIG. 3 shows the sealing strip and in particular the sealing profile 3 in the fully lowered position. The floor against which the Absenkdichtung seals, and the door are not shown here.

According to the invention, the sealing unit now has at least one means for detecting a property or a condition of the sealing unit. These means are usually sensors, transducers, counters or similar means. Hereinafter, the means will be referred to as a sensor, although other suitable means are intended to be encompassed by this term.

In FIG. 1 a first sensor 80 is arranged in the lower region of the sealing profile 3. This may be located at a single point in a limited area of the length of the sealing profile 3. In other embodiments, it consists of several parts, which are distributed over the length of the sealing profile 3. In other embodiments, it extends as in FIG. 2 Depending on the embodiment, the sensor is applied to the outside of the sealing profile 3, incorporated into the material of the sealing profile 3 or it is located on the inside of the sealing profile 3. Preferably, this first sensor 80 is a sensor for determining the contact pressure of the sealing strip on the ground.

In FIG. 1 a second sensor 81 is arranged on or in the mounting bracket 4. This detects, for example, the closing of the door leaf T and thus the position of the sealing unit as a whole with respect to the door frame, not shown here.

A third sensor 82 is in FIG. 3 recognizable. It detects, for example, the size of the stroke, for example, by detecting the distance between stationary housing rail 1 and movable sealing strip. Alternatively or additionally, for example, he can determine the number of reductions and increases.

In FIG. 2 a fourth sensor 83 is shown. This is located on the housing rail 1 and determines, for example, the age of the seal. It can thus be, for example, a counter or a clock. Alternatively, this fourth sensor 83 is arranged in or on the housing rail 1.

Also in FIG. 2 a fifth sensor 84 can be seen, which is connected to the lowering mechanism and / or arranged on the inside of the housing rail. It determines, for example, the bending of the leaf spring 6. A sixth sensor 85, which is likewise connected to the lowering mechanism and / or arranged on the inside of the housing rail, monitors, for example, the displaceability of the slide 7.

A seventh sensor 86, which is also in FIG. 2 is shown located at one or both ends of the sealing profile 3. For example, thereby the lateral contact pressure on the door frame can be detected. An eighth sensor 87 is located at the free end of the release button 5 and detects, for example, the force that is necessary to trigger the Absenkdichtung.

A ninth sensor 88 is found in FIG. 1 on the support rail 2. This sensor can be formed, for example, as a proximity sensor to determine whether the support rail 2 is present when closing the door leaf T on the door frame and could scratch it.

These are just a few examples of where and why the mentioned sensors can be used. They can also be used in other places, in particular, they can also be fixed in suitable modules, for example, arrange on the door frame or on the floor. The specified tasks of the sensors are to be understood as an example. Thus, other types of sensors with different detection options can be arranged at the specified locations.

The data of the sensors can be in an external control system, in particular in a as in FIG. 1 displayed building control system 9, evaluate, display and / or forward to readers. However, they can also be additionally or alternatively used in a sealing unit control system 9 'integrated in the lowering seal, as in FIG FIG. 3 shown, for the same purposes forward. The integrated control system may, for example, also be arranged in the door frame, in the floor, in the adjacent building wall or in the door leaf.

The inventive seal unit allows optimal adjustment and monitoring. It allows alternatively or additionally optimal maintenance.
