EP2050918B1 - Lowering seal with passage opening - Google Patents

Description

Technical area

The invention relates to a lowerable door seal with a passage opening for a locking bolt according to the preamble of patent claim 1.

State of the art

Out EP 0 338 974 is a lowerable seal for a door without a threshold known. It has an outer guide rail and a sealing strip held therein with carrier rail and sealing lip. The carrier profile rail can be raised and lowered via a lowering mechanism with respect to the guide profile rail. The guide rail is mounted in a door groove or on a lower end surface of the door, so that the lowered sealing strip rests on the floor and seals a lower gap of the door. It thus protects against draft and unwanted light immissions and also serves as sound insulation.

A possible lowering mechanism of such a door seal is, for example, in DE 195 16 530 described. Two or more leaf springs arranged one behind the other are fastened both to the guide profile rail and to the carrier profile rail. An actuating rod, which is connected directly or via a power transmission rod with the leaf springs, protrudes on one side at a front end of the seal. If the door is closed, this actuating rod is pressed into the seal, wherein it biases the springs. These push the sealing strip downwards direction Ground. When the door is opened again, the springs relax, the actuating rod is pushed out and the sealing strip is raised again.

Such gaskets are manufactured and sold in standard lengths. If a door now has a different dimension, the seal must be shortened on site or at the door manufacturer. For this purpose, in the case of the door seals which can be triggered on one side, a shortenable region has hitherto been provided on the end facing away from the actuating rod, over which the sealing strip, but not the lowering mechanism, extends. This allowed the rail to be cut off without having to disassemble the seal and shorten the lowering mechanism.

Furthermore, it is off EP 1 191 182 and EP 1 308 590 known to provide such seals with a through hole, which serves to receive a locking bolt of a cant or drive bolt. The bolt passes through the guide rail and the sealing strip. As a result, even with the use of such a bolt, the entire width of the door can be sealed, wherein the bolt can be actuated independently of the lowering mechanism of the sealing strip.

JP 11 117640 discloses a lowering seal with a through hole for a bolt. An actuating rod protrudes into a housing of the seal, the housing of a sealing strip projects.

FR 1 354 194 shows a one-sided releasable lowering seal.

Since now not only the length of the gasket but also the exact location of the passage opening must be adapted to the door, the latter seals can no longer be cut to the desired mass on site or in the door factory. They are therefore manufactured in the factory on individual customer request with the desired mass or they are subsequently shortened by the metal workers, in which case there is a risk that the housing is bent or the lowering mechanism or the sealing strip are damaged. This subsequent adaptation is only possible with seals with round through holes, but not at oval or otherwise shaped openings.

Presentation of the invention

It is therefore an object of the invention, a Absenkdichtung with a through hole to provide for a locking bolt, which can be adapted to the desired mass even after their preparation.

This object is achieved by a door seal with the features of patent claim 1.

The inventive door seal has a guide rail and a sealing strip, which is held in the guide rail and can be raised and lowered via a lowering mechanism. Further, it has a through hole for receiving a locking bolt and at least one actuating rod for automatically actuating the lowering mechanism, which projects the guide rail at a first end. The passage opening is arranged adjacent to a first end opposite the second end of the door seal. According to the invention, the door seal at the first and second end each have a shortenable region over which the guide profile rail and at least one sealing element of the sealing strip completely extend. These shortenable areas neither have the passage opening nor does the lowering mechanism project into these areas.

The through-opening preferably adjoins the shortenable region of the second end, wherein the through-opening or the passage region of the seal defined by it preferably adjoins directly to this shortenable region.

Preferably, the door seal has a core portion which includes the lowering mechanism and which can not be shortened without destroying the lowering mechanism. The passage opening or the passage area of the seal defined by it preferably directly adjoins this core area.

As a result, not only can the seal be shortened to the desired length, but the passage opening can also be adapted locally to the position of the locking bolt or to the type of lock. Usually, the seal is first shortened at the end close to the passage opening, ie the distance of this opening from the rail end is selected. Subsequently, the seal on the opposite End shortened and so the total length of the seal chosen.

The gasket, because it is customizable, can be produced inexpensively. It can be sold as a stock item because customization is now possible.

Further advantageous embodiments will become apparent from the dependent claims.

Ways to carry out the invention

FIG. 1 shows a door seal according to the invention, as it can be installed in a door groove of a threshold-free door or can be attached to a front edge of the door.

It has in this example essentially the same structure and lowering mechanism as in the documents of the aforementioned prior art.

The door seal has a guide rail 1, which is designed substantially U-shaped and open at the bottom. It has an upper bridge and two thighs up. In the upper area, near the upper web of the guide rail 1, two vertically projecting from the legs, inwardly projecting webs are preferably present on the inner sides of both legs, which preferably extend approximately over the entire length of the rail 1 and which together with the uppermost Bridge a guide groove for a lowering mechanism 3 described later form.

In the guide rail 1, a sealing strip 2 is arranged, which is preferably designed to be the same length as the guide rail 1. However, it may also be formed longer or shorter. The sealing strip 2 has a carrier profile rail 20 and a sealing element 21 arranged thereon. The sealing strip 2 can be raised and lowered relative to the guide rail 1. This is effected by a lowering mechanism 3, which at the same time holds or fastens the sealing strip 2 in the guide profile rail 1. The sealing element 21 is in the lowered state on the floor below the door, thus protecting against draft, light and sound.

The carrier rail 20 and the guide rail 1 are preferably made of aluminum. The sealing element 21 is preferably made of rubber, silicone or other elastomeric material. The sealing element 21 is shown here as a one-piece strip with a U-shaped cross-section, which is fastened on both sides to the carrier profile rail 20 and projects beyond these attachment points with two legs. Other forms of sealing elements, single or multi-piece, but can also be used.

The seal has in one end region a passage opening 5 for receiving a locking bolt, not shown here, for locking the door. The locking bolt is preferably part of a cant or drive bolt.

The passage opening 5 passes through the entire seal in the vertical direction from top to bottom. Preferably, it is elongated. But it can also be configured round or square. The passage opening 5 is essentially formed by aligned holes in the individual parts of the seal. So For example, the guide profile rail 1 has a first through-hole 50, the carrier profile rail 20 has a second through-hole 51, and the sealing element 21 has a third through-hole 52. These holes can be arranged centrally or laterally offset with respect to the longitudinal axis of the seal. Depending on the design of the carrier rail 20, there is no need for a through hole. The individual holes may be round or preferably oblong, in particular oval.

The actuating mechanism or lowering mechanism 3 is in FIG. 2 recognizable. This is preferably a mechanism such as that mentioned in the opening paragraph DE 195 16 530 is described. He is purely mechanically trained and works with spring force, being activated via an operating knob 6, which on one side dominates the guide rail 1. Under operating button 6 is understood here any embodiment which is suitable to mechanically trigger the mechanism when opening or closing the door.

The mechanism 3 has one or more leaf springs 31, 32, which are arranged one behind the other in the longitudinal direction. A connecting rod 35, preferably a threaded rod, is connected to the operating knob 6. The operating knob 6 may preferably be plugged or clipped, screwed to the rod 35 or otherwise releasably connected. When shortening the seal of the operating knob 6 is removed, the connecting rod 35 is shortened to the desired length and the operating knob 6 screwed or otherwise secured.

A first spring 31 is fixedly connected at a first end to the connecting rod 35, preferably welded. This rod 35 is also coupled to a power transmission rod 30 which is fixedly connected to a first end of the second spring 32. Preferably, they are welded. The power transmission rod 30 is slidably held guided in the above-mentioned groove of the guide rail 1. The first spring 31 and the second spring 32 are also fastened at their second ends by means of first fastening means 33 on the guide rail 1. In their central region, they are fastened by means of second fastening means 34 to the sealing strip, more precisely to the carrier profile 20.

The operating knob 6 is thus preferably non-destructively releasably connected to the lowering mechanism 3. This knob 6 is disposed at the end remote from the through hole 5.

The door projecting actuator button 6 presses when closing the door against the door frame and thus biases the springs 31, 32. The sealing strip 2 is thereby lowered automatically. When opening the door, the operating knob 6 can emerge again from the rail and the springs 31, 32 are relaxed. The sealing strip 2 is raised automatically.

A locking bolt, which passes through the through hole 5, can be operated independently of the position of the sealing strip 2.

However, other mechanical lowering mechanisms can be used. In particular, a two-sided triggering with rods projecting on both sides can be used.

According to the invention, the door seal now has at least four differently formed zones or regions in its longitudinal direction. In this case, the end zones 11, 14 arranged on both sides can be shortened and the two middle zones 12, 13 can not be shortened or not easily shortened. At least a portion of the integrally formed parts, such as support rail 20, guide rail 1 and sealing element 21, are preferably optically divided into these areas. In particular, the guide rail 1 preferably has an optical subdivision.

As in FIG. 1 Recognizable, the seal is in its longitudinal direction in a first actuation-side shortenable region 11, a subsequent thereto second region, the core region 12, a third adjacent thereto, the passage area 13 and adjoining the fourth region, the hole-side shortenable region 14 divided.

Based on FIG. 2 It is now clear why one area can be shortened and the others are not or can not be easily shortened. The core portion 12 includes the mechanical lowering mechanism 3 and therefore can not be shortened without destroying the mechanism 3. Preferably, the core portion 12 is not formed substantially longer than the mechanism 3. The passage portion 13 includes the through hole 5 and is just long enough so that the opening 5 still has a sufficient material border.

The two shortenable areas 11, 14 are penetrated only by short or removable parts of the seal. The first shortenable region 11 is essentially penetrated only by the sealing strip 2 and the actuating rod 6. The latter can preferably be removed before shortening this region 11 and then screwed in again. In this case, it can also be shortened separately, for example by being sawed off or by being formed in several pieces and simply removing a corresponding piece, e.g. unscrewed, will. The sealing strip 2 can be sawed through easily, either together with the guide rail 1 or separately to this.

The second hole-side shortenable region 14 is preferably even penetrated only by the sealing strip 2, so that the above applies here as well.

The two shortenable regions 11, 14 are preferably optically marked as such on the outside of the guide profile rail 1. They can be painted or divided from the remaining areas by a simple painted or indented stroke or a glued strip.

By shortening the second shortenable region 14, the distance of the passage opening 5 from the seal end is selected. By the subsequent shortening of the first shortenable region 11, the total length of the seal is adjusted.

Erster Bereich 11:

50 bis 150 mm, vorzugsweise 100 bis 150 mm;

zweiter Bereich 12:

20 cm bis 6 m;

dritter Bereich 13:

20 bis 30 mm und

vierter Bereich 14:

5 bis 80 mm, vorzugsweise 20 bis 80 mm, wobei 15 mm bei Metall- und 30 mm bei Holztüren bevorzugt sind.

The areas preferably have the following lengths:

First area 11:

50 to 150 mm, preferably 100 to 150 mm;

second area 12:

20 cm to 6 m;

third area 13:

20 to 30 mm and

fourth area 14:

5 to 80 mm, preferably 20 to 80 mm, with 15 mm being preferred for metal doors and 30 mm for wooden doors.

The seal is shortened in the figures and not shown to scale. In particular, the second region 12 is formed too short compared to the other regions.

Although only one type of seal has been described here, the teaching according to the invention with the two shortenable regions can also be applied to other seals, e.g. with other mechanical, electrical or magnetic lowering mechanisms, differently shaped sealing strips and other forms of guide rails.

The inventive seal thus allows a simple way of cutting the seal on both sides, so that on the one hand the length of the seal and on the other hand, the position of the through hole over a large area can be selected independently on site or at the door manufacturer.
