Abstract

A threshold profiled rod (10) with a cap (12) is fixed to the floor and an in principle T-shaped profiled rod (20) is fixed to the door leaf (1). It comprises a star-shaped tilting element (24) having three legs. This tilting element is linked at its apex to a rib (22) of the profiled rod by a soft strip (29) which serves as a hinge. In addition, the connection between an inner leg (26) of the tilting element and a horizontal rib (23) is provided by means of an elastic band (26a). The figure shows the open position. When the door is closed, a lower leg (25) of the tilting element strikes the inner side of the cap, the tilting element snaps over and an outer leg (27) of the tilting element covers the outer side of the cap, at the same time as a soft sealing strip (28) comes to lie on the outer side of the cap. When the door leaf is opened, the tilting element automatically snaps back into the open position.

Description

'Floor sealing device for doors'

The invention relates to a bottom sealing device for doors according to the preamble of the main claim.

10

Is known (DE-GM 86 16 133) an adjustable threshold seal for door leaves, in which two elastic lips sit on a flat arched threshold. This known threshold seal does not meet the requirements regarding window doors

Sealing, because in harsh weather the lips can be pressed inwards so that the necessary sealing against wind and rain is no longer available.

In view of the prior art mentioned, it is the object of the present invention to permanently equip a bottom-side sealing device for doors with a better sealing effect even in very harsh weather conditions.

25

This object is achieved by a sealing device with the features according to the main claim.

The subclaims have special variants of these

30 basic solution for doors with or without threshold and preferred embodiments of these special solutions to the content.

In such a sealing device, the movable gr attached to the bottom of the door leaf is a so-called

Tilting element, which is in an open position when the door is open and, when the door is closed, is inevitably guided into a closed position in which a soft one Sealing strip on this tilting element is pressed directly against the floor or against the floor threshold, so that the seal is thereby ensured. The soft sealing element is covered by an outer leg of the tilting element in such a way that water can run off. The soft sealing strip, the outer leg of the tilting element, the inner leg and an adjoining elastic strip form a permanent and secure barrier against the weather. At the beginning of the opening movement of the door leaf, the tilting element automatically snaps into the open position.

In the special embodiment of the sealing device for doors with a threshold, a third downward leg is provided on the tilting element, which strikes the threshold when the door leaf is closed, as a result of which the tilting element is guided into the closed position. In the course of the closing movement of the door leaf, the stop initially occurs on the hinge side of the door leaf and continues successively as the door leaf width is extended to the door lock side, the tilting element executing a torsional deformation. The elastic band with which the tilting element is connected to the profile bar fixedly attached to the door leaf causes in the

The closed position is a moment that increases the closing pressure, and in the open position a moment in the opposite direction of rotation that ensures that it rests on the profile bar of the door leaf and thus determines the open position. Otherwise, the threshold profile bar, which can be made of aluminum, for example, can be made so low that it can also be run over by a wheelchair, so that the sealing device is suitable for the disabled. In connection with a threshold, a sealing device according to the invention is particularly suitable for so-called French doors that lead to balconies or patios and are subject to the highest requirements with regard to sealing against rain and wind. In the special embodiment of a sealing device for doors without thresholds, the soft sealing strip of the tilting element lies directly on the floor in the closed position. To guide the tilting element into the closed position when the door leaf is closed, a disk-like release element is provided on the lock side on the lock side. A recess is formed on the inside with an inclined guide surface, through which the outer leg of the tilting element is grasped when the door leaf is closed and is moved so far that the tilting element snaps into the closed position. When the door is opened, the outer leg is moved upward by running up a further guide surface of the release element so that the tilting element then snaps back automatically.

The further invention according to the subclaims relates to particularly expedient embodiments of the profile bar, which can be attached either by inserting it into a groove or by screwing it onto a lower surface of the door leaf. Profile bar on the door leaf and tilting element are preferably extruded as a uniform profile, including the elastic band and the soft sealing strip, which serves as a hinge, for which parts soft or elastic plastic is used, while the remaining profile parts of the profile bar and the tilting element are made of hard plastic consist.

Furthermore, the present invention contains measures that are advantageous in addition to the basic solution for the rejection and drainage of the water. Exemplary embodiments of the invention are described below with reference to the accompanying drawings.

Through the sealing device according to FIGS. 1 and 2 bottom-side gap of a so-called window door are sealed, which window door separates an interior from a balcony or terrace. The sealing device must meet the highest requirements. One recognizes

Fig. 1 in a greatly enlarged representation of a door leaf 1, with a stop 2 and an outer surface 3. On the floor side between an inner floor 4 and a terrace floor 5, a threshold profile bar 10 made of aluminum is firmly attached. This has a rectangular stop part 11 on the inside, which merges into a curved threshold 12 (crest). There is an inclined surface 13 directly below, directed outwards, where water can run off. Above this surface rises an upper part 14, on which a further inclined surface, namely a drain surface 14b, is formed, which merges into a nose 14a. Openings 14c are formed on the upper part 14 so that the water has a free path on the lower inclined surface 13. 11 screw receptacles are formed in the stop part for receiving fastening screws.

In the lower area of the door leaf following the outer surface 11, a fixed profile rod 20 is attached, made of plastic. This profile bar 20 has a vertical cut 21, which bears on a vertical surface and bears on a lower surface with an angle 21c. The profile bar 20 is inserted with an upper section 21a of the vertical web into a groove 4 in the door leaf and held by a sawtooth-like profile. The upper section 21a is continued by a lower section 21b. An inclined web 22 branches off from this. A horizontal web 23 rests on a lower surface of the door leaf, with a stop 23a, which is continued in the form of a drip nose 23b.

A pivotable profile bar, a so-called tilting element 24, is assigned to the fixed profile bar 20. It consists of three legs arranged in a star shape, namely a lower leg 25 with a stop 25a, an inner leg 26 arranged at an obtuse angle thereto and an outer leg 27 which is approximately at a right angle to the inner leg 26 and forms an obtuse angle to the leg 25. The leg 27 merges into a bend 27a. An arcuate soft sealing strip 28 is held there.

10 The tip of the tilting element is connected to the branching web 22 via a soft strip 29. There is also a connection between the leg 26 and the horizontal web 23 via an elastic band 26a.

,, - The fixed profile rod 20 and the tilting element 24 are a uniformly extruded profile made of a hard plastic. The profiling also includes the elastic band 26a and the soft joint strip 29, but these parts are made of a soft or elastic plastic

20 exist.

In the open position, as shown in FIG. 1, the outer leg 27 lies against the horizontal web 23 in an obliquely upward position. This position is held 25 by the tension of the elastic band 26a, which in the position shown generates a moment in the sense of an opening movement. The leg 25 is directed downwards.

Fig. 2 shows the closed position of the tilting element 24. The leg 25 of the tilting element lies inclined on the crest 12, while the outer leg 27 is also inclined downwards. The soft weather strip 28 sits on the outer surface of the crest 12. This closed _g5 position is held by the tension of the elastic

Band 26a, the position of which generates a moment in the sense of a closing movement. The closing process from the position shown in FIG. 1 to the ^' position shown in FIG. 2 takes place from the beginning of the closing movement of the door leaf, where the leg 25 comes to rest against the dome 12 on the hinge side of the door leaf, so that the pivoting movement there Sense of closure. When the door leaf is closed further, the pivoting movement of the tilting element continues gradually up to the lock side of the door leaf until the position according to FIG. 2 is reached over the entire width of the door leaf. The tilting element is designed so that it can cope with the compelling torsional movements.

While the pivoting movement of the tilting element takes place successively when closing, the opening occurs when the door leaf is opened

Emergence of the soft sealing strip 28 to the tip 12, a snap effect a is suddenly moved back by the tumbler in the open position, the opening movement ^is assisted by the pressure of the leg 25 -

In the closed position according to FIG. 2, the lower door gap is blocked in full by the cap 12, the soft sealing strip 28, the outer leg 27 and further by the leg 26 and by the elastic band 26a. An additional lock is given by the branching web 22 and the soft strip 29. The water can drain through the inclined outer leg 27 and is then taken up by the lower inclined surface 13 for further drainage.

The horizontal web 23 of the profile rod 20 is continued by a nose 23a from where the dripping water is taken up by the drainage surface 14b.

3 to 5, a profile bar 30 is provided on the bottom, which in principle has the same shape as the profile bar according to FIGS. 1 and 2, wherein however, the inner rectangular part 31 from the outer part with the drainage surfaces in the area of the dome 32

Sections 32a is thermally separated.

Embodiment according to FIGS. 3 to 5 the same as in the embodiment of FIGS. 1 to 2. On a soft

Sealing strip 49 is additionally formed with a lip 49a directed downwards. This continues upwards in the form of a tip 49b, which at

Snap the tilting element back into the open position to ensure a soft and therefore noiseless stop.

6 to 8 serves to seal a threshold-free door. A profile bar 60 is attached to the bottom of the door leaf 1, with a horizontal web 61, a vertical web 62, which merges into an inclined web 63. A tilting element 64 consists of an outer leg 65 and an inner leg 66. A soft sealing strip 69 is attached to the outer leg. In the apex, the tilting element 64 is connected to the inclined web via an articulated strip 67. The inner leg 66 is connected at its end to the horizontal web via an elastic strip 68.

Fig. 6 shows the open position. The outer leg 65 is in an upward position on the horizontal web. This position is held by the elastic strip 68.

The sealing device on the door leaf 1 is assigned a release element 71 which, as can be seen in FIG. 8, is fastened to the door frame 70, specifically on the lock side. The trigger element is in the form of a disc that is screwed on. The disc has a recess through which an oblique guide surface 72 and an oblique guide surface 73 are formed.

When the door closes, the outer leg 65 of the tilting element abuts the guide surface 72 on the door lock side and is guided during further closing such that the tilting element tips over into the closed position according to FIG. 7, the sealing strip 69 lying directly on the floor. The required pressure is formed by the elasticity of the strip 68.

The return movement of the tilting element into the open position when the door is opened takes place by running the outer leg 65 onto the guide surface 73 of the release element.
