DE3526720C2 - Sealing device for the lower door gap of a door leaf - Google Patents

Abstract

The sealing device is intended for sealing the lower door gap of sliding door leaves. While a pivoting door leaf is held in the stop position by a lock, this is not always the case with sliding door leaves. For this reason, the sealing device is designed so that the door leaf is held in the stop position solely by the friction generated by the pressed rubber strip (6). In the lowered position of the lowering bar (5), the springs (20) are tensioned, but horizontal restoring forces are no longer effective. When the door leaf hits, a coupling (3, 16) is produced between a slide at the end and an element on the door frame. This coupling ensures that when the sash is pushed away from the stop position, the slides are pulled out again and again, so that the springs can relax and the lowering bar goes up. The coupling releases automatically when the outer slide has reached its protruding position.

In a known sealing device of the aforementioned type (DE-OS 24 58 496) are when the Lowering bar has reached its lower position, the rising elements of the spring are still attached to the Inclined surfaces of the slide, so that there is still a horizontal force in the sense of a push back in effect is. However, it cannot take effect if the door leaf is in the closed position by a lock is held, which is usually the case with pivoting door leaves. Because of this, the aforementioned is known door sealing device is also limited to the use of corresponding doors.

The object of the invention consists in the design of the sealing device of the aforementioned type, suitable for sliding door leaves.

The basic solution to this problem results from the features according to the main claim. The subclaims have different variants of the housing

sequschnitts, the slider, the springs and the tensile strength Coupling to the content

If a sliding door leaf with a sealing device according to the invention, the stop position (closed position) has been reached, then the lowering bar lowered, the rubber strip rests on the floor with pressure and the sash is in this position held off the floor solely by the friction of the rubber strip. This position can be a restoring force do not cancel, as the elements of the springs that have accumulated on the sloping surfaces of the slides are no longer on the inclined surface, but on the bottom of the horizontal slide surface. So there is no force acting which tries to push the slide back again. The stop position of the sliding door leaf can can only be canceled by external forces by moving the wing just a few millimeters from the stop pushes away, which the elasticity of the rubber strip also allows by the fact that between the end slide and a tensile coupling is established for the door leaf, When the door is moved back, the slide is briefly held in place until the slider opens Elements again rest on the inclined slide surfaces and the slide together with the lowering bar are automatically moved back into the open position by the spring forces. The tensile coupling of the door frame releases automatically so that the sliding door leaf can move freely again.

According to the further invention, the springs can be designed as ribbon springs or as wire springs. the accruing parts can be formed directly by shaping the springs or by the Cylindrical parts attached to springs, which due to their circular cross-section run well onto the inclined surfaces can. The invention also relates to various embodiments of coupling elements for example a push-button connection, a locking connection using two balls or a magnetic adhesive connection. By suspending the lowering bar on at least two springs a stable position of the lowering bar will still be achieved the lowering bar has the option of being in the closed position for the purpose of adapting to the floor to adjust something at an angle.

In a door leaf 1 of a sliding door, a housing 10 is grooved at the bottom which than in cross section rectangular profile bar that is open at the bottom is formed Chamber 11, a middle chamber 12 and a lower chamber 13 open at the bottom divided the lower chamber takes up vertically movable also a lowering strip 5, which is also rectangular in cross section, on which a rubber strip 6 is attached to the floor for sealing. The upper chamber and the middle chamber are used to accommodate the lowering mechanism.

This lowering mechanism includes two slides, namely an outer slide 14 and an inner slide 17, which are slidably mounted in the central chamber 12. These two slides are motion-wise beheaded by a rod 19 which extends in the area the upper chamber 11 extends the outer slide 14 protrudes a little at a front end of the housing. This position is through one Stop 18 fixed on which the inner slide 17 rests. An inclined surface 15 is formed on each slide

A profiled spring (band) is assigned to each slide, either as a band spring or as a wire spring can be formed. A U-bend 21 is formed on each spring. The spring is like this in the area of the U-bend wide like the middle chamber 12, from which the U-bend is received. The assembly is carried out by Insertion of the U-bend up to a stop which is defined by a pin 27.

From the U-bend, a sloping leg 22 is formed on the spring, which is in an ascending one Leg 24 extends in between in the apex 23, the spring is connected to the ceiling of the lowering strip 5, in this area the spring is so narrow that it extends into the area of the lower chamber 13 can expand. An inclined surface 25 adjoins the leg 24, corresponding to the inclined surface 15 on the respective slide. From the inclined surface 25, the spring settles in the form of an end section 26 away which rests freely movable on the lowering bar

On the protruding part of the outer slide 14 is a buttonhole 16. This corresponds to a button 3 of a fixed one Coupling element on the door frame 2. A corresponding fixed coupling element 4 is on the opposite End of the housing 10 attached

In the state according to FIG. 1 the sealing device is open, i.e. the lowering bar is in the upper position ucd the door leaf can be moved freely. If the stop position on the door frame 2 according to FIG. 3 reached then the valve 14 has been pushed in, a releasable connection being made between the button 3 and the buttonhole 16.

The pushing in of the outer slide 14 also has a corresponding displacement of the inner slide Result, by coupling the two slides with the rod 19. By moving the two slides the inclined surfaces 25 of the springs on the inclined surfaces of the slide slid down until the Position according to FIG. 3 is reached where the apex on the spring between the leg 24 and the inclined surface 25 on the underside of the respective slide lies the two spring apexes connected to the lowering strip 23 have lowered themselves, that is, the lowering bar has lowered overall. Though the feathers

are stretched, no horizontal restoring force is transmitted to the two slides because the associated Inclined surfaces no longer lie against one another. By lowering the bar S has also become after F i g. 4 of the rubber strips 6 applied to the floor. The sliding door leaf is in the stop position due to the friction held.

The stop position according to FIG. 3 is reversed by pulling back the wing a few millimeters, which allows the elasticity of the rubber strip 6 to easily. During this short retraction movement, the Outer slide 14 pulled out by the tensile coupling connection 3 / J6, with the result that the The lowering bar goes up and the door leaf can be moved freely automatically.

The button 4, which is firmly attached to the other end of the housing, serves to establish a tensile connection with the Outside slider of an adjoining Sciiiebeiüi hill to manufacture.

The sealing device according to FIGS. 5 to 10 has in principle the same housing 30 as that previously described Sealing device. The cross section of the housing 30 is again divided into an upper chamber 31, a middle chamber 32 and a lower chamber 33. The upper chamber 31 is kept relatively low, the middle chamber 31 serves as a path for the slide and the lower chamber 33, which is open at the bottom, takes one Lowering bar 46 with a rubber strip.

In this sealing device, three slides are used in the web 32, namely in the central area the two slides 34 and 37, which are connected to one another by a bar 39, and the end slide 50. This is connected to the slide 37 by a rod 45. As already mentioned, the sliders are taken from track 32. The upper chamber 31 is provided to accommodate the bar 39 *

The two slides 34 and 37 are each assigned a spring, which in this case is a wire spring 40. As shown in FIG. 8 can be seen, an elongated U-shape with two parallel legs. The spring ends 41 are inserted into a block 43, which is received in the middle chamber 32 so as to be immovable. The other, bent end of the wire spring 40 is articulated to a block 44 which is firmly attached to the lowering bar 46 is attached. Between the two blocks are the spring legs through holes in a cylinder 42 led.

The two slides 34 and 37 are each assigned to a spring, wherein in the open position, the F i g. 5 shows, in each case the inclined surface 35 of the slide rests on the cylinder 42. If the door leaf is closed, so If the end slide 50 is moved to the left by elements on the door frame, the two slides 34 and 37 slide over the same path to the left, the two cylinders 42 run onto the inclined surfaces, are thereby forced to move downwards, which has the consequence that the free Ends of the springs, which are hinged to the lowering bar, move downwards, that is, the The lowering bar also goes down and the rubber strip sits on the floor. This position (Closed position) is from FIG. 6 can be seen. The two cylinders 42 have the inclined surfaces 35 essentially overflow and hang on to the lower horizontal slide surface. The two feathers are then although tensioned that means the restoring forces are present, but a horizontal backward movement of the Sliders can no longer cause them. The closed position of the door leaf remains in place if no locking has taken place in a lock.

By moving the slide into the closed position, a coupling element 60 is provided on the door leaf. This coupling element has an abutment 61, the task of which is to hold the slide 50 in place, when the housing 30 is moved towards the door frame, as shown in FIG. 10 shown.

A neck 62 is formed axially on the abutment 61 and merges into a head 63 via a conical surface 64. An axial bore 51 is provided in the slide 50 to accommodate these parts. Two radial bores 52 extend from this bore in the end area, each of which receives a ball 53. A part of the respective ball is also received by a bore 54 in the housing wall 30. If the slide 50 is pressed into the closed position according to FIG. 10 by the abutment 6i from the opening according to FIG. In this way, a tensile connection between the coupling element 60 and the slide 50 is established. This has the consequence that the slide 50 is held when the door leaf moves to the left again when the door is opened. However, if the slide 50 reaches a joint position with the housing according to FIG. 9. so the two balls have the possibility of dodging in the radial direction in the bores 54 of the profile bar 30 and the connection is canceled, so that the further movement of the door leaf is free.
