Description

TITLE

DOOR SEAL WITH FASTENING ELEMENT

TECHNICAL AREA

The present invention relates to a door seal, a clamp of this door seal and a door wing for receiving the door seal.

STATE OF THE ART

Door seals for sealing a lower end face of a thresholdless door are known. They should prevent light transmission and also provide sound insulation. Depending on the embodiment, an air passage should be avoided. Furthermore, door seals for exterior doors are known, which protect against driving rain and wind. These door seals can be mounted not only in or on a lower end face of a door leaf but also in or on upper and lateral end faces of the door leaf.

These door seals can be designed, for example, as sliding seals or as lowerable door seals. Slip seals usually have a housing rail with a sealing lip or attached thereto. Lowerable door seals have a housing rail and a sealing strip arranged therein with an elastomeric sealing profile. The sealing strip is automatically lowered when closing the door leaf relative to the housing rail and raised automatically when opening the door leaf. The release is preferably carried out purely mechanically by a protruding release button, the provision of the sealing strip in the raised basic position is usually achieved with return springs. Such lowering seals have been known for years and are described, for example, in EP 0 338 974, DE 19 516 530, EP 0 509 961, DE 3 526 720, DE 3 418 438 and DE 3 427 938. If the door seal is fastened in a groove of the door leaf, the housing rail is usually screwed to the door wing with two fastening angles. A leg of the mounting bracket is inserted for this purpose below an upper web of the housing rail and the leg arranged at right angles is screwed over the web of the housing rail to the end face of the door leaf.

In EP 1 486 639 B1, a clip-type fastening element is disclosed, which surrounds the upper web of the housing rail and which is hammered by means of nail pins in the top surface of the groove to fix the housing rail in the groove.

EP 3 095 949 A1 discloses a multiply bent fastener with two U-shaped interventions. Depending on the desired mounting position, the upper web of the housing rail is inserted into one of these two interventions and the fastener is fastened by means of a screw in the groove.

EP 2 055 888 A2 describes a fastening means in the form of two leaf springs with end claws. These leaf springs are arranged on each outer side surface of the housing rail and they fix the inserted into the groove housing rail. This type of holder is suitable for wooden doors.

EP 2 949 855 A1 likewise shows leaf springs which are formed on or held on the housing and which point downwards. These fixings are only suitable for wooden doors. In addition, they require a relatively large amount of space, so that a relatively wide groove must be present.

PRESENTATION OF THE INVENTION

It is therefore an object of the invention to provide a door seal with a fastener, which is particularly applicable to plastic doors and metal doors. This object is achieved by a door seal, a clamp and a door leaf with the features of claims 1, 11 and 15.

The erfmdungsgemäße door seal with a housing rail and held in the housing rail sealing strip has a fastener for attachment of the front side rail of the housing rail in a groove of a door leaf. The fastening element is a clamping element, which is designed for attachment to the front or bottom of the housing rail. It is advantageous that no further aids and tools are necessary for mounting. The fastener and thus the door seal can be mounted without tools. In addition, no screw with the door are necessary. Preferably, the clamping element can also be easily removed again, for example with a simple lever element, e.g. with the shaft of a screwdriver or by means of a ballpoint pen.

A further advantage is that the clamping element can form relatively narrow. It does not require more space in the transverse direction of the seal than the seal itself. This fastener can also be used for very narrow seals, without the groove and thus the thickness of the door leaf must be increased.

The fastener can be produced inexpensively and it hardly affects the appearance of the door leaf with mounted door seal. Preferably, the clamping element is resilient. Preferably, it engages the front side of the housing rail. Alternatively, it may be firmly connected to the housing rail or the door leaf.

The clamping element is hereinafter referred to as "clip". However, this term is understood to mean not only clamping elements which themselves pinch something, but also elements which are held in place by clamping, in particular by spreading. Preferably, the clamp is designed for clamping reception in a frontal window of the door leaf or in a window which is arranged on an underside of the door leaf and thus allows a lower-side attachment. As a result, the clip can be arranged so that it hardly protrudes the surface of the door leaf and thus hardly affects the overall appearance. The window can have different shapes. Preferably, it is rectangular. For example, it is formed by a slot. The arrangement on the front side has the advantage that the door does not have to be unhooked to assemble or disassemble the door seal. The arrangement of the window on the bottom has the advantage that the window and, depending on the embodiment of the clip, and the clip itself are not visible when mounted sealing device.

Preferably, the clip is integrally formed, in particular of metal or plastic. This minimizes the Flerstellungskosten and simplifies storage and installation.

Preferably, the housing rail of the door seal on two lateral legs and an upper web, which connects the two lateral legs together. The clip is preferably inserted below this web and comprises in a preferred embodiment with a U-shaped engagement the web and an intermediate bottom of the door leaf. Preferably adjoins this U-shaped engagement a resilient hook member to fix the clip within a recess of the door leaf.

This recess in the door leaf is shaped differently depending on the embodiment of the clip and the door. Preferably, the recess is a frontal window or a frontally open cavity and the false floor is a lower floor or it is formed by two spaced-apart lateral lower webs of this window. In the latter case, the intermediate bottom is thus not formed continuously in the transverse direction of the sealing arrangement.

The clamp according to the invention preferably has a base leg and a parallel leg spaced therefrom and approximately parallel thereto, which together form the U-shaped engagement. Preferably, the base leg engages in the housing rail and the parallel leg is designed to rest on the intermediate bottom of the door leaf. The distance between the base leg and the parallel leg preferably makes it possible to jointly receive the upper web and the intermediate bottom. The base leg preferably has a free end, and a fixing element for fixing the clip in or on the door leaf is preferably arranged on the parallel leg.

Preferably, the clip has a hook element for fixing the clip relative to the door leaf. This hook element is preferably designed to queue in an end-side inner wall of the window. Preferably, the hook element is integrally formed on the U-shaped engagement, wherein it is connected in a preferred embodiment via an obliquely extending leg with the parallel leg.

In a preferred embodiment, the two approximately mutually parallel legs are connected to each other via a first arc, wherein the first sheet projecting in the longitudinal direction of the hook member or aligned therewith. The longitudinal direction is defined by the two approximately mutually parallel legs or by the longitudinal extent of the housing rail.

The skew leg preferably forms an angle with the parallel leg, the hook element being located above the first bow. The helical leg can be pushed in the direction of the parallel leg to mount the clip, for example, to push the clip through the window of the door leaf.

The inventive clip has other forms in other embodiments. If the window is arranged on the underside of the door leaf, the clamp preferably has at least one horizontally extending base leg, an upward vertical leg and a hook element integrally formed thereon, for example in the form of an obliquely downwardly extending free leg.

The hook element is preferably in all Ausführungsfbrmen to a angefonten leg, for example, the vertical leg or the skew leg out pressed so as to squeeze the clip and push through the window in the cavity behind it.

The inventive door leaf for receiving this door seal has on a front side or on an underside a window for receiving the clamping element. Preferably, the door leaf has a groove which extends along a lower end side of the door leaf and which is designed to be open at the bottom. Above the groove, a window in the door leaf is arranged on at least one lateral end side of the door leaf. The window preferably leads to a cavity which has a lower intermediate floor. Alternatively, the window is arranged on the underside of the door leaf, for example in the groove base.

The floor does not have to be completely closed towards the groove in both embodiments. It can also be formed by two lateral upper webs extending in the longitudinal direction of the groove, which can be covered by the U-shaped engagement of the clip together with the upper web of the housing rail.

The window is preferably spaced from the groove above the groove. Other positions or an aligned adjacency to the groove are also possible depending on the embodiment.

Depending on the embodiment, the door leaf is made of metal, plastic, glass, wood or combinations thereof.

Further embodiments are given in the dependent claims.

DESCRIPTION OF PREFERRED EMBODIMENTS

FIG. 1 shows a door leaf 6 with a door seal according to the invention. It has a housing rail 1, which is usually formed substantially U-shaped and open at the bottom and two lateral, approximately parallel legs 10 and one of these two legs 10 interconnecting upper web 11 has. Below the upper web 11 preferably extend over the entire length of two lateral ribs 12 which project horizontally into the interior of the housing rail 1. Together with the upper web, they form a channel 13 in which a slide, not shown here, of a lowering mechanism runs. The housing rail 1 is preferably formed as a profile rail of a metal, for example of aluminum.

In the housing rail 1, a sealing strip is held. The sealing strip has a carrier rail 2 and a sealing profile 3 arranged on this carrier rail 2. The support rail 2 is also a profile rail, preferably made of metal, in particular aluminum. The sealing profile 3 is formed in one or more pieces and made of an elastomeric material, preferably made of silicone or rubber.

The support rail 2 is connected to the lowering mechanism, not shown, and is lowered automatically when closing the door leaf 6 together with the sealing profile 3 until the sealing profile 3 rests sealingly on a building floor. When opening the door leaf 6, it is automatically raised again together with the sealing profile 3. The sealing strip can thus be moved automatically relative to the relative to the door leaf 6 stationary housing rail 1.

The lowering mechanisms used for this purpose are well known and are therefore not described. Usually, they have springs, in particular leaf springs, to connect the support rail 2 with the housing sections 1 and to ensure the restoring force when lifting the sealing strip.

The lowering mechanism can be triggered by an electric motor, magnetically or mechanically. In this example, the preferred one-sided mechanical release is represented by means of an actuating knob 4, which projects on one side of a lateral end face 62 of the door leaf 6 and is pressed when closing the door leaf 6, the slide and thus the lowering mechanism actuated. The operating knob 4 can be seen in Figures 1 and 3 to 5. These figures show the seal in each case in the raised state.

For fixing the housing rail 1 in a groove of the door leaf 6, an inventive fastening element is now present on at least one, preferably on both end sides of the housing rail 1. If such a fastening element is present on only one side, then the housing rail 1 is fastened on the other side with other known means, or the nozzle is formed such that it forms a bearing surface for the housing rail 1.

The fastening element is designed as a resilient clip 5. It has, as is clearly recognizable in FIGS. 7 and 8, a planar base leg 50, which merges via a first arc 51 into a plane parallel leg 51 which extends approximately parallel to the base leg 50 and is arranged at a distance. The two legs 50, 52 form a common U-shaped engagement and define a longitudinal direction L.

A second arc 53 connects to the second end of the parallel leg 51 and leads to a bevel 54 which forms an acute angle with the parallel leg 52, directed upward from the base leg 50 and points with its second end in the direction of the first arc 51 , At this second end, a third arc 55 leads to a hook element 56 which has a free upwardly directed end 57. The free end 57 is preferably recessed from the outer surface of the first sheet 51 or flushed therewith. Preferably, the free end 57 of the hook member 56 is not on this side of the remaining areas of the clip 5. As can be seen in Figure 7, the base leg 50 and a portion of the first sheet 51 are preferably formed wider than the remaining areas, wherein the free end of the base leg 50 is tapered. The remaining regions of the clip 5 preferably have a constant width and / or preferably a constant thickness. They are each designed plan. Preferably, the entire clip 5 is formed over the entire surface. Alternative forms, in particular with recesses, widths and changes in thickness, however, are also possible.

The clip 5 is preferably made of metal, in particular spring steel, or made of a plastic.

As can be clearly seen in FIG. 1, the door leaf 6 has a window 60 above its groove. This leads into a cavity 63 of the door leaf 6, which is bounded below by an intermediate floor 61. The intermediate bottom 61 is formed in this embodiment by the groove bottom in the door leaf, as can be seen in Figures 3 to 6. Other arrangements are possible.

During assembly, the housing rail 1 is first inserted with the sealing strip in the groove of the door leaf 6. This is shown in FIG. Subsequently, the bracket 5 is inserted with its base leg 50 below the upper web 11, more precisely in the channel 13, the housing rail 1. For this purpose, the clip 5 is slightly compressed, so that the upper part of the clip 5 can be inserted through the frontal window 60 of the door leaf 6. The parallel leg 52 comes to rest on the intermediate bottom 61 in the cavity 63, so that the U-shaped engagement of the clip 5 now includes the upper web 11 of the housing rail 1 and the intermediate bottom 61 of the door leaf 6 together. This position is shown in FIG.

The clip 5 is now pressed further through the window 60 until the first sheet 51 is present at the end face of the housing rail 1 and / or on the front side of the window 60 and thus the clip 5 can not be pushed further. In this position, the flap element 56 has hooked in the upper region of the window 60, ie it stands on the back, and the previously compressed clip 5 has again partially or completely relaxed. This can be seen in FIG. The window 61 is preferably in height smaller than the relaxed spring, but larger than the compressed spring so that the window 61 can be inserted into the cavity 63.

As can be seen in Figure 8, forms the hook member 56 with the sheet 55 is an S-shape, the middle arc forms a negative angle. Upon a force from the left on the seal, e.g. by the operation knob 4, this geometry causes an increased hooking of the clip 4 in the window. This prevents that the clip 4 and thus the housing rail 1 is moved when closing the door.

FIG. 6 shows the same situation as in FIG. 5 in a variant of a door leaf 6. In this example, the free end 57 of the hook member 56 protrudes the first sheet 51 and thus forms on this side the most projecting part of the clip fifth

As can be clearly seen in FIGS. 5 and 6, the bracket 5 barely projects toward the door leaf 6 at the end. Figure 2 shows a view of the door seal in the assembled state with fully inserted clip 5. Here it can be seen that the clip 5 is very narrow and thus does not affect the choice of the width of the door leaf.

In the figures 9 to 11 a second erfmdungsgemässe embodiment is shown. The bracket 5 in turn has a base leg 50, a first arc 51 and a parallel leg 52. However, the parallel leg 52 is formed relatively short compared to the base leg 50. It merges into an upwardly directed vertical leg 54 ', which preferably forms exactly or at least approximately a right angle with the parallel leg 52. At the vertical leg 54 'is an obliquely downward to the first sheet 51 inclined towards free leg 56' is arranged, which forms a hook element.

The associated door 6 in turn has the window 60 for insertion of the clip 4 a. In this case, however, the window 60 is located on the lower side of the door leaf 6, again leading into a cavity 63 above the door seal. The lower end face may be the lowest surface of the door leaf 6 or, as in this Example, be arranged in a groove bottom 64 a receiving groove for receiving the housing rail 1.

The front side is a smaller access window 65, preferably only a small through hole exists, into which a pin can be inserted to release the clip 5 and thus remove the housing rail 1 again.

This clamp also allows a tool-free mounting of the sealing device on or in the door leaf. 6

In the first exemplary embodiment, the sealing device can also be mounted or removed even when the door leaf 6 is already mounted, since the housing rail 1 and the clamps 5 can be pushed into the door leaf 6 at the end.

In the second embodiment, the Klammem 5 are pushed frontally on the housing rail 1, but the housing rail 1 is then pressed from below into the groove or on the lower side of the door leaf 6 and the brackets 5 are pushed through the downwardly directed window 60 of the door leaf 6 and clamped in the underlying cavities 63. This second embodiment has the advantage that the user sees only a very small, barely visible opening and the larger window 60 is covered by the seal.

FIGS. 12 and 13 show a third embodiment according to the invention. Again, the window 60 is arranged on the underside of the door leaf. Again, there is a small access window 65 on the front. The clip 5 is inserted in this example in an upper opening 14 of the housing rail 1. The opening 14 is, depending on the embodiment, an upwardly open groove, for example a C-groove, or it is merely a window, which is arranged at one or both ends in an uppermost web 11 of the housing rail 1.

The clip 5 may in turn have different shapes. Preferably, it has a 50, a molded-on vertical gifts! 54 'and one at this molded, obliquely downwardly directed free leg 56 'on. The free leg 56 'in turn forms the hook element. The clip 5 is in turn held in the window 60 by means of the free leg 56 '. It can be pressed against the vertical leg 54 'as in the second embodiment in order to push the chamber 5 through the window 60. It can also, as in the second embodiment, by a pin which is pushed through the access window 65 into the cavity 63, press in the direction of vertical leg 54 'to remove the clip 5 again through the window 60. This embodiment has the advantage that the clamp 5 is no longer visible from the outside when the housing rail 1 is mounted.

The door seal with the inventive fastener is suitable for use in plastic doors and metal doors. She can also train very narrow.
