Description

TECHNICAL AREA

The present invention relates to a door seal system according to the preamble of patent claim 1.

STATE OF THE ART

Door seals are used in areas where soundproofing and draft protection are desired. Likewise, they should conclude light-tight. Simple door seals are so-called sliding seals whose sealing lip or brush projects beyond a lower end face of the door leaf.

Furthermore, lowerable door seals are known, which usually consist essentially of a housing in the form of a downwardly open, U-shaped rail, a held in this housing and relative to this sliding sealing strip with a sealing element and a drive mechanism for lowering or lifting the sealing strip consist. Usually, the sealing strip automatically lowers when closing the door by a longitudinal force acting on an actuating rod and sets the mechanical lowering mechanism in operation. However, it is also possible to provide a manually operable drive mechanism. Such door seals are made, for example EP 0 338 974 . DE 299 16 090 and EP 0 509 961 known. These door seals have proven themselves. In particular, the door seal according to EP 0 338 974 stands out for its particularly efficient sealing performance thanks to the one-piece sealing lip, the legs of which slide against the guide rail.

However, these seals can be in low or zero energy houses with controlled ventilation, especially in Minergie ^® homes, not use. In such buildings, a ventilation system is present, which blows air in part of the rooms via ventilation grille in the wall, in the floor or in the ceiling and sucks it in other rooms also located in the wall, in the ceiling or in the bottom suction. The aim of ventilation is to heat fresh air drawn in from outside by means of the exhausted air flowing outwards in order to minimize the energy required to heat the rooms. In this case, preferably each room have an air supply and discharge opening, which is connected to the ventilation system. In cheaper variants, the exchange of air takes place between the rooms, for which purpose small ventilation grilles are arranged in the door or the walls. Alternatively, the doors do not close very tightly, so that the air exchange is ensured. Usually, a relatively large gap is left between the lower edge of the door and the floor. However, there is no sound insulation and light shimmers from one room to the other.

In EP 1 498 569 It was therefore proposed to provide pressure equalization openings in the sealing lip or in the seal housing. However, these are sometimes insufficient for adequate ventilation of the rooms.

In EP 1 936 097 is a door sealing system for use in Minergie ^® -Houses disclosed. The seal housing is arranged in an outer rail, wherein between these two rails a continuous air passage extends from one side to the other side of the door. In the air duct sound damping elements in the form of deposits of rock wool or felt are arranged. These should allow a certain soundproofing.

In WO 2010/142053 a door seal system is proposed with an air duct, which ensures air circulation from a first side of the door leaf to a second side of the door leaf. In order to improve the sound insulation, a sound-absorbing resonator is present in the air duct. The resonator may be formed by the door seal itself, for example by the guide rail or an outer rail surrounding the guide rail.

Especially in closed rooms, however, there is an increased need for air renewal and thus an increased need for air exchange with adjacent rooms. This is usually solved by fans, which are arranged in wall openings. These fans are visible to everyone and can negatively affect the aesthetics of the room. A subsequent installation of such fan requires a major structural change, since the wall breakthrough must be created. In addition, the airflow generated in the room is often perceived as disturbing.

PRESENTATION OF THE INVENTION

It is therefore an object of the invention to allow increased air renewal in rooms without compromising the freedom in designing these spaces. In particular, the air renewal in existing buildings should be improved without major structural changes.

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

The door sealing system according to the invention has a door seal for sealing a lower or upper side of a building door leaf and an air duct, which in the sealing position of the door seal air circulation from one side of the door leaf and the longitudinal side of the door seal on the opposite side of the door leaf and the opposite longitudinal side the door seal allows. According to the invention, the door sealing system has at least one fan, which conveys air through this air duct.

The air duct is thus in the area of the door seal and preferably leads around it. The door seal system also provides an active element for ventilating the room.

The combination of the existing air duct in the door seal system with at least one fan improves the air exchange without major structural measures. In addition, this ventilation system is almost invisible, as it is in the lower or upper area of the Door leaf is located. Existing buildings can be easily retrofitted by either replacing the entire door leaf or retrofitting existing door leaves with this sealing system including a fan. The circulating air flow preferably extends over the entire width of the door and is thus barely perceived. The system according to the invention can be used effectively in buildings without central ventilation. It can also be used in combination with a central home ventilation system.

Preferably, the at least one fan is motor driven, preferably electric motor operated.

The power supply of the fan can be done via the in-house power grid or via a battery.

The at least one fan can be in continuous operation and / or manually switched on and off. In a preferred embodiment, it is switched on when closing the door and off when opening the door leaf. The switching on and off can be done for example via an activated when closing the door switch or by another closing circuit. The switching on and off can also be done by lowering and raising the door seal. If it is coupled with a movement of the door seal, so it can be activated even when the door is not closed, for example by the door seal in this state can be lowered manually or motorized. If the at least one fan is only in operation with the door closed and / or with the seal lowered, energy consumption is minimized. Since the fan is used only when needed in this case, it also has a longer life. In one embodiment, the fan is connected to an electronic controller which controls the operation of the fan in response to external conditions. For example, a CO ₂ sensor and / or a hydrometer can be present and the fan can be switched on when a threshold value is exceeded. The controller is in a preferred embodiment, a central home control or it can be connected to this.

The at least one fan is arranged on or in the door leaf. Preferably, he is in Area of the door seal and arranged above this. As a result, the air duct can be optimally formed, and the mode of action is increased. Furthermore, the inventive system can thereby compact and space-saving form, so that the creative freedom in the design of the door leaf is limited only slightly. In particular, the door leaf can thereby be formed so that the observer does not notice the door seal and the fan at first sight.

The at least one fan is preferably fastened to the door seal or to an outer housing accommodating the at least one fan and the door seal. This facilitates the assembly, and it is only a single groove in the door necessary to accommodate the entire system. The door seal system is preferably designed for placement in a groove of a door leaf and for attachment in or on this door leaf. The system may additionally or alternatively be designed for attachment to the lower or upper end side of the door leaf, wherein it projects beyond this. A lateral arrangement in the lower or upper region of the door leaf leaf is possible. Preferably, in the door seal system according to the invention, the fan and the door seal are connected to one another, wherein this connection is approximately airtight. This increases the efficiency.

In preferred embodiments, the at least one fan is a compact or miniature fan. In a preferred embodiment, the at least one fan is a cross-flow fan, which blows air in the longitudinal direction of the door seal. However, this cross-flow fan is designed so that it promotes air from one longitudinal side of the door seal on the other longitudinal side. This can be achieved, for example, by forming a suitable flow channel in a housing of the fan.

There may be more than one cross-flow fan. Preferably, however, only a single cross-flow fan is present. Preferably, the door seal has in its longitudinal direction at a first and a second end, wherein the fan is arranged in the region of one of these ends so that it blows air in the direction of the other end. At the opposite end, a second cross-flow fan can be arranged with opposite orientation.

In another embodiment, the at least one fan is at least one axial fan, which blows air in the direction transverse to the longitudinal extent of the door seal. Preferably, a plurality of axial fans in the direction of the longitudinal extent of the door seal are arranged side by side and distributed over approximately the entire longitudinal extent of the door seal.

In a preferred embodiment, the door seal system comprises an outer housing in which the at least one fan and the door seal are arranged. Preferably, the outer housing has a U-shaped cross-section and it is designed to be open towards the end face of the door leaf to be sealed. Preferably, the air duct is formed in the outer housing between outer walls of the door seal and inner walls of the outer housing.

A common outer housing is not absolutely necessary. Fan and seal may also be mounted together or individually on or in the door leaf, wherein the fan promotes air along the door seal from one side to the other side. The air duct may for example be formed between the door seal and the groove of the door leaf.

If an outer housing is present, it preferably has two legs and a web connecting these two legs, wherein the at least one fan is arranged adjacent to the web.

In order to enable an optimal air duct, the door seal is preferably arranged on both longitudinal sides spaced from the outer housing.

The door seal may be a sliding seal with a sealing lip or brush. Preferably, however, it has an automatically lowered when closing the door leaf and automatically raised when opening the door leaf sealing element. The sealing element can be actuated magnetically, motorized or inductively. Preferably, however, it is mechanically, for example spring loaded, activated. The aforementioned lowering mechanisms with actuation rod which can be activated on one side are preferred embodiments.

The door can be a hinged door or part of a sliding door.

DESCRIPTION OF PREFERRED EMBODIMENTS

In the FIGS. 1 to 6 a first embodiment of the inventive door seal system is shown.

According to FIG. 1 This door seal system is mounted in a groove N, which is present in a lower edge of a door leaf T. Alternatively, the door sealing system can also be arranged on an upper end edge, on a lateral surface of the door leaf T or on a lower or upper end face of the door leaf T.

As in the FIGS. 2a and 2b can be seen, the U-shaped groove N is stepped or offset formed. At least one, preferably at both lateral ends of the groove N, this is narrower and less deeply formed than in the central region. However, the groove N may also have a constant over its entire length width and depth.

The attachment of the door sealing system on or in the door T is done by known means. In particular, an outer housing 1 accommodating all parts of the door sealing system can be present, which is hat-shaped with legs parallel to the end face of the door leaf T. These legs are preferably screwed to the end face of the door leaf T. This type of attachment is suitable for consistently trained grooves as well as stepped grooves.

In the embodiment shown here, the outer housing 1 has a U-shaped cross section, as shown in FIG FIG. 4 is clearly recognizable. It may be recessed in the groove N or, as in FIGS. 1 and 2 shown, flush with the lower edge of the door T end. Although protruding outer housing 1 are also possible, but less desirable in practice.

The outer housing 1 encloses a seal housing 2 of a door seal. Outer housing 1 and seal housing 2 are preferably profiled rails made of aluminum or plastic. The seal housing 2 also preferably has a substantially U-shaped cross-section and has a web and two mutually parallel legs through this web.

Preferably, the door seal is designed as Absenkdichtung, as is known in the prior art. In this example, in the seal housing 2 is a support rail 3, a fixed to the support rail 3 sealing element 4 and a lowering mechanism, not shown, wherein the support rail 3 and the sealing element 4 can be raised and lowered together about this lowering mechanism relative to the seal housing 2. The sealing element 4 is formed here in one piece and has in this example on the seal housing 2 adjacent lateral legs 40 and an obliquely downwardly projecting projecting sealing lip 41, which extends over the entire length of the seal. However, the sealing element 4 can also be formed in several pieces and / or have a different shape and other attachment points on the support rail 3, the seal housing 2 or at other points of the seal. The lowering mechanism preferably has leaf springs, which can be actuated via an actuating rod running parallel to the longitudinal direction of the seal. The actuating rod ends in an operating knob 5, which protrudes on one side of the door seal, as shown in FIG FIG. 3 is recognizable. When closing the door leaf T of the actuating rod is thus pressed and the force is transmitted to the leaf springs.

Other types of lowering mechanisms and also other types of door seals, in particular sliding seals and brushes, can also be realized with the inventive idea.

In this example, the seal housing 2 protrudes the outer housing 1 on both sides, as in FIG. 3 is recognizable. In this way, the sealing system according to the invention can be mounted in a recessed groove N of the door leaf T. For this purpose, a mounting bracket 6 is present, which engages with a leg below the web of the seal housing 2 and is screwed to a second, approximately perpendicular leg to the end face of the door leaf T. This is in FIG. 1 good to see. The sealing system mounted in this way is barely visible from the outside, only the front sides are visible.

The seal housing 2 is arranged at a distance in the outer housing 1, so that on both its longitudinal sides, a gap 8, 8 'is formed. These spaces 8, 8 'form part of an air duct.

The inventive door seal system further comprises at least one fan or fan 7. The fan 7 is arranged above the web of the seal housing 2, as shown in the FIGS. 4 and 6 is recognizable. Preferably, the fan 7 is mounted on the web of the seal housing 2, for example screwed, clamped or glued or otherwise sealed.

The fan 7 is surrounded by the outer housing 1, as in FIG. 5 is recognizable. The fan 7 may additionally or alternatively be attached to or in the outer housing 1.

This fan 7 is preferably designed as a miniature fan, so that it is designed to save space as possible and can be operated with low energy consumption. It can be battery operated or connected or connectable to the mains. For example, a connection to the mains can be made by closing the door via a contact, e.g. in the door frame, done. Cable ties, e.g. to the door lock, be present.

The fan 7 is arranged in the region of one end of the seal. Preferably, however, it is located at a distance from the end of the seal housing 2. This allows the arrangement in a remote groove N of the door leaf T. It can also be used several such cross-fan. In particular, a transverse fan may also be arranged in the region of the other end of the seal housing 2. However, at least one fan 7 is preferably arranged in the region of that end to which the door leaf T is pivotally mounted in the door frame; i.e. hinge side.

In this embodiment, the fan 7 is a cross-flow fan. It blows air along the longitudinal direction of the seal housing 2. The fan 7, however, has a flow channel 70 with an inlet 71 on one longitudinal side of the seal housing 2 and an outlet 72 on the opposite longitudinal side of the seal housing 2. This can be, for example, as shown here, achieve by suitable design of the fan housing. The inlet 71 opens into the first gap 8 on a first longitudinal side of the seal housing 2. The outlet 72 opens into the second gap 8 'on the second opposite longitudinal side of the seal housing 2. This is in FIG. 4 good to see. As a result, this fan 7 promotes air from one side of the door leaf to the other side and thus from one room of the building to another. The gaps 8, 8 'and the flow channel 70 thus form the air duct. This arrangement ensures that even with the door closed and with the door seal lowered a sufficient exchange of air between the rooms can take place. This is even possible in particular central ventilation system.

In FIG. 7 is a first variant of the inventive door seal system according to the FIGS. 1 to 6 shown. Here, the seal housing 2 is provided with holes to as sound-absorbing resonator to act. Other types of resonators, in particular those in WO 2010/142053 can also be used in the door seal system according to the invention.

In the FIGS. 8 to 10 is a further embodiment of the inventive door seal system shown. Here is also a cross fan 7 available. However, it is arranged azentrisch in the outer housing 1, so that its inlet 71 is not directed downwards as in the embodiments according to the FIGS. 1 to 6 , But is laterally directed to the side wall of the outer housing 1 out. Its outlet 72 is directed downwards in this example. Alternatively, however, the inlet 71 may be downwardly oriented and the outlet 72 may be laterally aligned.

In another, not shown embodiment, inlet and outlet 71, 72 end laterally. For this purpose, only the outer housing 1 must be wider than the fan 7. The fan 7 can be arranged azentrisch or centric in the outer housing 1, as long as an air duct is formed from one side to the other side of the seal.

In all of these embodiments, the seal housing 2 is preferably centric, i. arranged along the longitudinal center axis of the outer housing 2 in this. However, it can also be arranged acentric.

Incidentally, the variations mentioned in the first embodiment including the use of resonators are also possible in this embodiment.

In the embodiment according to the FIGS. 11 to 13 a plurality of radial fans 7 are arranged over at least part of the length of the seal housing 2. Preferably, these are in turn secured to the seal housing 2. The variations according to the previous embodiments are also possible here.

The radial fan 7 can be distributed over the entire length of the seal housing 2, preferably evenly distributed, arranged. However, they could also be in the area of one end. Preferably in the area where the door is in Door frame is pivotally mounted.

The radial fans 7 direct the air from one side of the door T to the other side. A special design of a flow channel is therefore not necessary in this example. This has the advantage that the sealing system can be made narrower overall.

In FIG. 15 a damping element 9 is shown, which is fixed to the inner sides of the two parallel legs of the outer housing 1. Preferably, it is glued. The damping element 9 is used for soundproofing. It is thus a sound absorber. It can be designed as a simple sound-insulating mat, for example made of felt, or as a Helmholtz resonator. It preferably extends approximately over the entire length of the sealing system.

The inventive door seal system allows a sufficient exchange of air even with the door closed.
