Door panel with ventilation openings

The invention relates to a one-piece or multi-piece door panel, in particular a vertically movable door panel, consisting primarily of lamellae with foam, e.g. polyurethane, inside the housing, which is provided with ventilation openings to allow air to pass to the outside of the door panel. between the spaces, and having a sealing strip at the downward edge of the closing-10 position, comprising a deformable hollow bead or lip formation which, in the closed position of the door leaf, rests against the floor of the door opening to be closed.

15 Doors such as those at issue here, which have ventilation openings for ventilation and which are suitable for spaces in which there is otherwise no ventilation, such as garages, may have a different structure. This is especially the case for doors with a vertically movable yk-20 inner or multi-part door leaf. In addition to one - piece door panels, these are, above all, door panels which consist of successively articulated,. panels such as rolling doors, but above all articulated! through the doors.

5 Door panels or panels such as those at issue here often consist of a double-walled sheet metal casing with a foamed plastic filling in between. Subsequent fabrication of the openings in a door panel or door panel panel that is fabricated as a continuous step causes considerable difficulty and results in cutting areas that are prone to rust.

The placement of the ventilation openings - in particular in the form of longitudinal holes running parallel to the lower edge 15 of the door - in the area of the mounting strip, which acts as a connection between the lower edge of the door or its downward end wall and the elastic sealing profile, must be closed. a vertical dimension of a corresponding size so that it can contain ventilation openings. In the closed position, the space between the lower edge of the door leaf or its downward end wall and the floor or floor edge shall be as small as possible, taking into account any unevenness in the floor; the same applies to the security list ’; when using a hollow profile when facing an obstacle.

German application 35 03 314 discloses a rope-shaped profile seal of flexible material for windows, doors and the like, the seals of which have a plurality of sealing lips in the foot area, some of which are provided with air-through openings.

The object of the invention is to provide a door panel of the type mentioned at the beginning, the ventilation openings of which are inconspicuous and of advantageous construction, and which are located in the lower area of the door panel in the closed position 10.

With a door leaf such as the one mentioned at the outset, this object is achieved in that the ventilation openings are formed in the web-15 area formed above the bead or lip formation and are covered at least from outside the door leaf by heavy downwardly hanging cover against heavy rain and snow.

By fitting the ventilation openings according to the invention inside the sealing strips not only is the door panel itself free of ventilation openings and its appearance undisturbed, but as a result the structure of the mounting strip between the lower edge of the door panel and the sealing strip in the closed vertical position is relatively low and attaching. The mounting strip can thus be formed with respect to its shape without the need for • · ***. taking into account the ventilation of the space separated by the door panel, but • · · it can be formed on its own according to its fastening function and the fitting of the door panel to the lower edge or the end of the lower door panel. The sealing strip with ventilation openings, on the other hand, depends only on the structure of the fastening strip · and is thus available in different types of door panels, regardless of their closed down wall structure, which has the great advantage of having the door panel constructed of similarly shaped panels. adhere to each other in a certain way, e.g. in such a way that in no position of use it is possible to insert fingers into the gap between successive panels.

98752 4

Since the harmful gases are heavier than air, ventilation in the vicinity of the floor is particularly favorable, which is achieved by the arrangement according to the invention in an optimal manner by placing the ventilation openings in the sealing strip.

5

Another advantage is that the seal with ventilation openings according to the invention can be fitted to the fastening strip without hindrance instead of the seal according to the previous construction method or a similarly shaped fastening structure.

The sealing strip formed or made into a rope profile is preferably made afterwards, in particular by stamping.

In order to fasten the sealing strip to the lower edge of the door leaf, a fastening strip, e.g. aluminum, is used in a particularly advantageous structure, which in turn can be made in profile and the profile-shaped fastening structure has groove-shaped grips behind it.

20

The ventilation openings may be covered with a screen or lattice-shaped cladding to prevent the entry of coarser objects.

. . ·. In a preferred embodiment, the seal is prefabricated such that, ____; 25 that the ventilation openings or part of them are only installed in the desired way at their place of use. In this case, • · ”* can be condensed. taking into account the edging of the ventilation openings, the pre- • · · pre-stamping and the raw materials surrounded by the edging are left undisturbed, in particular from the corner portions of the openings. These parts are then removed on site from the seal ϊ. · .: to meet ventilation requirements. In another embodiment, the seal is provided in preparation with all ventilation openings, which are then covered with one or more adhesive tapes or the like.

1 ,! through. At the place of use, the adhesive tape can be completely, 35 or partially removed, thus opening the ventilation openings.

This and other preferred embodiments of the invention appear from the subclaims, in particular with reference to 98752 5 shown in the drawing and the exemplary embodiments described below, in which Figure 1 shows a perspective view of the end and vertical cross-sectional side of a vertically movable door panel part 1; Fig. 2 shows a partial view of a vertical cross-section of the lower part of the lower panel according to Fig. 1 in two different embodiments of the sealing strip.

10

The door leaf marked with the common reference 1 or its lowest door panel has a seal marked with the common reference 3 at its lower edge 2, which is fastened to the end wall 8 of the lower edge 2 of the panel 1 by means of a fastening strip 4. Both the sealing strip and thus the fastening structure as well as the fastening strip are made in profile, the sealing strip being of rubber profile and the fastening strip being of metal, in particular aluminum profile, whereby the fastening structure can be pushed or pressed into the fastening strip. The fastening strip is constructed in a C-shape at least with respect to the connection area of the fastening structure of the sealing strip and in such a way that the open gap between the free sides of the C-profile is downwards. Closed! a cross-section of the sealing strip protrudes into this opening of the sealing strip. 25 the upper strip of the T- or I-shaped fastening structure 6, as can be seen from the corresponding figures, and in such a way that the fastening strip engages behind the free-ending side of the T- • · or I-shaped upper cross-member of the fastening cross-section • · · '· Closed. In another embodiment, the fastening strip 5 has two grooves open to the outer and inner side of the door panel 30, into which are inserted • gripping flanges 7 built into the side walls of the sealing profile, which are open upwards, as shown in Fig. 2.

An embodiment of the sealing strip is shown in Figures 1 and 2/1. The seal has a base part 10 between the fastening structure 6 and the hollow profile 12 facing the floor, which, reaching a certain vertical height, runs parallel to the lower edge 2 of the door leaf 1 98752 6. The hollow profile 12 may initially be viewed as a generally hollow bead portion, but this embodiment also provides an embodiment of a sealing strip that acts as a safety strip formed so that when the door leaf moves and the seal encounters an obstacle, a corresponding emergency signal is deformed.

In this case, the ventilation openings 14 are in the base part 10 of the sealing profile 10, being primarily constructed as a row of longitudinal openings running parallel to the lower edge 2 of the door panel 1.

In order to ensure a wind-resistant sealing device against the floor and against the northern edge part, with the door plate in the closed position, external and internal sealing lips 13 are formed primarily in the area close to the floor of the sealing strips, as can be seen from the figures. These sealing lips prevent the ingress of dust, liquid or the like. In order to protect the ventilation openings 14 from the ingress of moisture, in particular during an oblique rain, it has guards 15 which are primarily constructed in the area of the fastening structure. hanging downwards and covering the ventilation openings, being separate from their mouths, whereby - as shown in the figures - 1; 25 shown by the dashed arrows - they do not block the air transfer chute ... through the ventilation openings 14.

In the example according to Fig. 2/2, the sealing strip is constructed • · · V * seen downwards from the fastening structure 6 - here always with the door plate 30 in the closed position - into a through-web portion 11 which::: becomes a sealing lip 13, and where the ventilation openings 14 are located.

• · «· ·

As can be seen from Figures 1 and 2/1, the sealing profile 35 can be made in advance so that the area of action of the opening formed by the ventilation openings can be adjusted as desired. Referring to Fig. 1, this can be done in such a way that the sealing wall in question is delivered in such a way that the circumferential edges of the openings of the ventilation opening 98752 7 are only partially stamped, whereby e.g. the material parts 18 inside the edge are closed only. from the corner areas of the sealing wall. At the place of use, the number of openings 5 required for ventilation can then be determined by breaking open these parts of material surrounded by the edge. According to the example according to Fig. 2/1, the ventilation openings 14 in the base part 10 are covered unilaterally or double-sided - already at the factory with adhesive tape 19, which can be removed at the door leaf where required, whereby also the total area of opening can be determined.

As can be seen from the figures, the formation of the sealing strip 3 is independent of the downward end wall 8 of the lower edge 2 of the door leaf 1 in that the corresponding adaptation to this extreme shape 15 can take place by means of the fastening strip 4. Figures 1 and 2 show the cross-sectional contours of this lower end wall, as it appears in the case of panels which, in no position, at their underlying joints, are possible for fingers to grip along their trajectory. Due to the inexpensive manufacture, only panels formed in the same way are used for the entire door panel, so that the end wall 8 placed at the bottom is constructed in accordance with the seam dimensions between the panels. By means of the corresponding curvature of the fastening strip, this design of the lower edge area of the door panel 1 of the end wall 8 can be taken into account.
