Description

The present invention relates to a door leaf for a door assembly.

Out DE 10 2010 012 357 A1 is already known a door assembly with a folding in a Zargenfalz door leaf, which has a resilient portion, in the form of a over the entire height of the door leaf extending hollow profile which is provided in a cutout of the door leaf edge and has a quadrangular cross-section. When the door is closed, the flexible area extends on both sides of the folded edge of the Zargenfalzes. The thickness of the plastic profile is chosen to approximate the thickness of a human finger, particularly a child's finger, and the compliance of the plastic profile is selected so that the resistance forces exerted by a human finger against compression are readily sufficient for complete compression of the hollow profile ,

The DE 10 2011 113 820 A1 shows as also explained above DE 10 2010 012 357 A1 a door leaf, in which a rectangular or square hollow profile as a resilient element in a cutout of the door leaf edge on the hinge opposite side of the door leaf in the region of the band edge and / or the lock edge is so as to prevent pinching of a finger between the hinge opposite side and a corresponding Zargenfalz or at least mitigate. In addition, a substantially square element for protection against edge impacts is shown, which has a substantially C-shaped groove, in which a correspondingly shaped web is provided on the door leaf for supporting the edge protection element on the door leaf.

The US 2,747,237 describes a door whose door leaf is provided with compliant elements both at the band edge and at the lock edge. The resilient elements, which are substantially square in shape, are fastened with L-shaped brackets to the hinge edge of the door panel. In order to pivot the door leaf on the frame pivotally, a piano hinge-like hinge is provided.

In order to lock the door in frame frame A, unlike conventional room, apartment or building doors vertical locking bars are provided which engage in the horizontal verlaufenden sections of a four-sided circumferential frame frame.

DE 20 2011 110 026 U1 describes a finger protection arrangement with a roller blind, which covers the gap forming during the opening of the door between the Zargenfalz and the hinge opposite side in the band edge.

The US 20080190029A1 also shows only a cover of the gap between the door and frame, which is formed from curved or flat slats.

The object of the present invention is to provide a door leaf for a door assembly or door, the optimal stability and without sacrificing the room finishes or the usual sealing function even with additional door functions such as sound insulation, fire and smoke protection and / or wet and damp aptitude improved

Finger protection guaranteed. The present invention is intended in particular to increase the safety against a risk of crushing on the secondary closing edge (band edge) of the door.

This object is achieved by the door leaf for a door assembly according to claim 1. Further developments of the invention are specified in the subclaims.

In particular, by the inventive L-shape of the flexible, resilient element, hereinafter referred to as a compliant element, the finger guard can be realized in a door assembly having the door panel according to the invention, in an advantageous manner, since the resilient element over both a part of the back (Hinge opposite side) of the door leaf, so the enveloping in the Zargenfalz side of the door leaf as well as on the band facing longitudinal side (band edge) of the door leaf extends and thus covers the entire crimp-critical area.

Advantageously, the resilient element is releasably connected to the door leaf. The releasable connection allows the compliant element to be easily replaced or replaced, e.g. in case of wear or damage. An exchange can be made without the removal of the door panel. Furthermore, the resilient element can be retrofitted and installed in already produced door arrangements of, for example, wood and / or plastic.

Advantageously, the resilient element is connected via at least one tongue and groove connection with the door leaf, which is a cost-efficient, simple yet secure connection option, which also makes it possible to replace the resilient element without tools or other aids. Alternatively, the resilient element can also be connected without tongue and groove connection, for example, by an adhesive bond with the door leaf.

Advantageously, the resilient element is provided in a recess which is designed such that the resilient element is formed flush with the rear side (tape opposite side) of the door assembly and the first longitudinal side (band edge) of the door leaf. In this way, in addition to optical and hygienic aspects, the standard geometry of the door panel can be maintained. Features such as the dimensions in width, height, thickness and cross section, ie the contour, are retained. The inventive L-shape is further ensured that the resilient element can be used in a cutout of the door leaf, for the production of which not too much material must be removed, which has a positive effect on the stability and stamina of the door panel and thus on the raumabschließende as well as sealing effect against fire, smoke, sound, cold and draft.

In order to facilitate the retrofitting of existing door leaves, especially on the construction site, it is provided in an advantageous embodiment of the invention that a profile strip is provided on the band edge of the door leaf to form the recess. In principle, the profiled strip can be made of any suitable material, such as wood, plastic or metal, but not the stability and stamina of the door leaf to impair, but rather to increase, without significantly increasing the weight of the door leaf is provided in particular that the profile strip is made of aluminum.

Advantageously, the resilient element is designed as a hollow profile, whereby material is saved and further influences and ensures the flexibility of the element and its compliance.

Conveniently, the resilient element has integrated ribs or webs, which serve the stability of the hollow profile.

Advantageously, at least one rib extends substantially parallel to the first longitudinal side, that is approximately perpendicular to the hinge opposite side, whereby the stability of the resilient element in the closing direction of the door is increased, thereby ensuring a sufficient tightness between the door leaf and rebate seal when the door assembly is closed. In the squish direction, that is approximately perpendicular to the first longitudinal side (band edge) of the door, however, the flexibility of the compliant element required for effective finger protection is maintained since the rib can be easily bent transversely.

Advantageously, the rib has at least one bend, whereby the stability or the flexibility of the resilient element in the closing direction of the door during manufacture can be defined as desired.

Advantageously, the resilient element is formed of an elastomer, whereby the flexibility of the element is ensured.

Fig. 3 shows a closed door assembly 1 with the door panel. 7

Fig. 4 shows the door assembly 1 in section (CC; DD) with a frame 2 from Fig. 3 , which has a Zargenfalz or fold 3, wherein on a wall 4 by means of at least one first screw 51, a mounting bracket 5 is attached to the at least one second screw 52, a first half-shell 21 (folding part of the frame) is attached. The first half-shell 21 is connected via a connecting screw 8 with a second half-shell 22 (cladding part of the frame). The two half-shells 21, 22 and together form the frame 2. Further, a door leaf 7 is provided, which cooperates with the frame 2 and with the fold 3.

At the locations where the first half-shell 21 and the second half-shell 22 touch the wall 4, a first seal receptacle 25 or a second seal receptacle 26 is provided, in which a first wall seal 23 and a second wall seal 24 are accommodated. The first wall seal 23 and the second wall seal 24 are designed as resilient seals to ensure a flush installation, easy installation and, if necessary, a silicone-free installation of the door assembly 1.

The fold 3 is a part of the first half-shell 21 and has a Falzdichtungsaufnahme 27 for receiving a rebate seal 31 in order to ensure a seal against fire and smoke, sound, cold and draft, and possibly odors through the door assembly 1.

Further, door hinges 6 are provided, e.g. are connected by screws with the first half-shell 21. In order to ensure the opening and closing of the door assembly 1, the door leaf 7 is connected to the door bands 6, so that it is pivotally mounted on the frame 2. Usually, the door hinges 6 pins, tabs or fishing, which are connected to the door panel 7.

For adjusting the door leaf 7 in the frame 2 and in particular within the fold 3, the tape tabs of the hinges 6 are screwed with fasteners 10, which are embedded in the band edge 73. In order to arrange the resilient element 9 over the entire door height, in particular in the region of the door hinges 6, the connecting elements 10 are arranged behind the resilient element 9.

Fig. 5 shows the section EE of in Fig. 3 shown door assembly 1. In this view, neither the door hinge 6 nor the connecting element 10 can be seen.

Fig. 6 shows a detail sectional view of the door leaf 7, wherein the door leaf 7 has a recess 77. The recess 77 has a substantially L-shaped cross-section in a plane parallel to the upper edge 75 and lower edge 76 of the door leaf 7 and extends with a first length L1 along the tape opposite side 72 of the door leaf 7 and with a second length L2 along the tape edge 73rd of the door leaf 7. The edge created by the L-shaped recess 77 is suitably bevelled. The angle of the edge is determined, on the one hand, by a finger, for example, which can be securely clamped between the band edge 73 and the fold 3 without being pinched by the remaining edge of the door and, on the other hand, by the positioning and dimensioning of the door edge under the resilient element This results in an angle of 110 ° to 140 °, preferably 120 ° to 130 °, which is formed with the band edge 73 of the door panel 7.

Further, a first groove 78 and a second groove 79 are provided on the legs of the L-shaped recess 77. The grooves 78, 79 are approximately at 90 ° to each other, thus extending substantially perpendicular to the respective leg surface of the L-shaped recess 77 in the door leaf, and extend in the present embodiment However, the grooves 78, 79 may also be at an angle to each other, which is greater or less than 90 °.

As in the Figures 8a, 8b and 8c shown, it is possible according to other embodiments of the invention, at the band edge 73 of the door leaf 7 a profile strip 80, 80 ', 80 "to install, which optionally forms the recess 77 with the band edge of the actual door leaf 7, instead of the recess 77 directly from the Door leaf 7. In the illustrated embodiments, the grooves 78, 79 (see. Fig. 6 However, it is also conceivable to form the profile strip 80, 80 ', 80 "narrower than the door leaf thickness and a bottom of the groove 78 forming the area against the belt edge 73' of the door leaf 7, so that the groove 78 is then formed together by the corresponding area of the profiled strip 80, 80 ', 80 "and the band edge 73'.

The use of the profile strip 80, 80 ', 80 "facilitates the retrofitting of already produced doors, especially on the construction site, since the existing door leaves 7 need to be cut to length preferably only on the side of the strip edge over the entire height of the door to the width of Door leaf to reduce the corresponding thickness D of the profile strip 8. After attaching the profile strip 80, 80 ', 80 "on the door panel 7 can then be used as in the above-described embodiment of the invention, the resilient element 9.

The profile strip 80 for forming the recess 77 may be made of any suitable material, such as solid wood, plastic, or metal. Preferably, however, an aluminum hollow profile is provided that can be easily screwed or glued to the correspondingly reduced in width door leaf. The mounting holes to be provided for the screwing in the profile strip do not interfere because they are concealed by the mounting of the resilient element 9 by this.

As in FIG. 8a is shown, the profile strip 80 is formed as an aluminum profile, which at its resting on the band edge 73 'of the door leaf 7 side 81 two to each other has parallel springs 82 which can extend over the entire length of the profile strip 80. The springs 82 can also be provided only in sections. Furthermore, it is possible to provide only a single spring. The springs 82 are then placed in corresponding grooves 83 in the belt edge 73 'of the door panel 7. Such Nutfederverbindung between profile strip 80 and door leaf 7 not only increases the stability of the attachment of the profile strip 80 on the door panel 7, but can also contribute to increase the stability of the entire door leaf.

In another embodiment of the invention, which in FIG. 8b is shown, which is to be arranged on the door leaf 7 side of an aluminum profile without springs smooth. Such a profile strip 80 'can also be screwed or glued.

FIG. 8c shows a profile strip 80 "in which the resting on the band edge 73 'of the door leaf 7 side or surface 81" is also formed without springs. For a plastic profile, as in FIG. 8c is indicated, however, as in the embodiment according to FIG. 8a, one or two springs may be provided wholly or partly over the length of the profiled strip.

The recess 77 is configured such that it can receive the resilient element 9. Fig. 7 shows the substantially L-shaped resilient element 9, which is designed as a hollow profile. The resilient element 9 has a first leg 91 and a second leg 92 and has between the two legs of the L an inclined surface 93 which is adapted to the chamfer of the recess 77 of the door panel 7. In this way, the spatial extent of the resilient element 9 is increased, in particular in the crush-critical area, but without negatively influencing the stability and door functions of the door leaf 7. It is also conceivable that the resilient element 9 has no inclined surface 93 and the area between the two legs 91, 92 is formed at right angles or rounded. In this case, a cavity is provided between the resilient element 9 and the recess 77 (not shown), which facilitates the assembly of the resilient element 9. In extension of the inclined surface 93 extends in the interior of the hollow profile in the region of the first leg 91, a first rib 94, which serves to reinforce the resilient element 9. Furthermore, one is second rib 95 and a third rib 96 which extend within the second leg 92 and also serve to reinforce the resilient element 9. The rib 96 also forms a limiting flank for the partial recess of the resilient element 9 for passing the tape tab of the door hinge 6 to the underlying connecting element 10 or to the belt substructure.

Furthermore, a fourth rib 97 is provided which, when the door arrangement 1 is closed, extends from the strip-facing inner wall of the resilient element 9 in the direction of the fold 3 or the seam seal 31 so as to ensure optimum sealing when the door arrangement 1 is closed. At the same time, this arrangement ensures maximum flexibility in the crimping direction, ie in the event that when closing the door assembly 1, e.g. a finger between the frame 2 and the second leg 92 of the resilient element 9 device. The fourth rib 97 also has a kink, in order to obtain some flexibility in the closing direction despite improved stability. Due to the nature of the buckling, the stability and the flexibility of the resilient element 9 in this direction can be defined as desired during production. All the ribs advantageously extend, like the resilient element 9 itself, over the entire height of the door leaf 7.

It is also conceivable that the two legs of the L not by a straight surface, but z. B. are connected to each other by a rounding or other profiling. The recess 77 would not necessarily have the same contour for this, so that a simpler introduction of the resilient element 9 can be ensured in the recess 77. Furthermore, the number and arrangement of the ribs may differ from the arrangement described above.

The resilient element 9 has a first spring 98 on the first leg 91 and a second spring 99 on the second leg 92, which are adapted to fit into the first groove 78 and the second groove 79, respectively, around the resilient element 9 Way safely connect to the door panel 7. The first spring 98 and the second spring 99 extend over the entire height of the door leaf 7 and are each perpendicular to the respective leg surface of the L. In the present embodiment, the first spring 98 is at the end of the first leg 91 and the second spring 99 are spaced from the end of the second leg 92. It is also conceivable to arrange the springs 98 and 99 elsewhere in the resilient element 9, wherein their angle to the respective leg can be greater or smaller than 90 °. Furthermore, it is conceivable that the resilient element 9 and / or the ribs and / or the grooves 78, 79 and / or the springs 98, 99 extend partially or intermittently over the height of the door leaf 7. This may possibly be required in the region of the hinges 6 or the connecting elements 10 or in the region of the door lock. Matching to the executed Nutfräsung then the springs 98 or 99 of the elastic element 9 are partially removed. However, in view of the possibility of retrofitting doors, it is advantageous that the grooves 78, 79 can be produced as continuous cutouts. The number, shape and size of the springs may differ from the design described above.

The resilient element 9 is adapted to the recess 77 such that its outer surfaces is flush with the hinge opposite side 72 of the door and the belt edge 73 of the door leaf 7. However, it is also conceivable that the resilient element 9 protrudes beyond the tape opposite side 72 and / or the belt edge 73 or with respect to the belt opposite side 72 and / or the belt edge 73 is sunk. Furthermore, the resilient element 9 concludes flush with the top edge 75 and bottom edge 76 of the door panel 7. However, it is also conceivable that the resilient element 9 is formed shorter with respect to the height of the door leaf 7 or is integrated only in certain areas of the door leaves.

In order to ensure optimum crush protection, in particular for fingers, the resilient element 9 is dimensioned with respect to its two legs 91, 92 such that in the space formed by the hollow profile of a finger of a child or possibly the finger of an adult can be added in order to reduce the risk of crushing and its consequences even when the door assembly 1 is completely closed.

By the L-shape of the resilient member 9, it is so connected to the door panel 7 that even bonding allows sufficient strength of the connection, since the pressing force of the seam seal 31 can not shear the adhesive joint by the L-shape; there is a positive connection. Likewise, a pinched finger with the Force direction always substantially perpendicular to at least one adhesive surface or flank.

It is also possible that the resilient element 9 is provided with vents (not shown) which prevent air cushions used to prevent squeezing of e.g. Fingers counteract required compression of the compliant element 9.

It is also possible to fill these through openings or the open cross-section of the compliant element 9 with a resilient material or material to achieve the desired compression of the compliant element 9.
