ARRANGEMENT CONSISTING OF A GLASS DOOR LEAF AND AN AUTOMATIC DOOR SEAL

Description

[0001] The present invention relates to an arrangement comprising a glass door leaf and an automatic door seal, wherein the door seal has a housing which has a first leg, a second leg and a web connecting the two legs, wherein an outer side of the web abuts the lower side of the door leaf at a joint and is glued there to the lower side of the door leaf.

[0002] Athmer oHG produces and sells automatic door seals for glass doors that can be glued to the bottom of the glass door leaf. These seals have a housing with an H-shaped cross-section. The housing is placed on the bottom end of the door leaf, and an adhesive is applied to the joint. This creates not only an adhesive connection but also a positive connection. The connection between the door leaf and the housing is particularly durable.

[0003] DE 20221112 U1 describes an arrangement according to the preamble of claim 1.

[0004] A disadvantage of the known solution with an H-shaped housing is that for an optimal form-fitting and visually appealing connection between the housing and the door leaf, a housing must be provided for each thickness of the door leaf.

[0005] This is where the present invention comes in.

[0006] The present invention is based on the object of proposing an arrangement of a seal and a door leaf of a glass door, in which the thickness of the housing of the seal and the thickness of the door leaf can be selected independently of each other.

[0007] This object is achieved according to the invention by a. that the housing has a substantially U-shaped cross-sectional profile, and neither the first leg nor the second leg of the housing projects beyond the joint between the door leaf and the housing, b. that the arrangement has a first cover which is glued to an outer side of the first leg of the housing and which extends from a free end of the first leg in the direction of an upper end of the door leaf at least beyond the joint between the housing of the seal and the door leaf, and c. that the arrangement has a second cover which is glued to an outer side of the second leg of the housing and which extends from a free end of the first leg in the direction of an upper end of the door leaf at least beyond the joint between the housing of the seal and the door leaf.

[0008] The covers allow the seal to be attached to the underside of the door in a visually appealing manner. The first and / or second cover can have the same cross-sectional profile or different cross-sectional profiles. A small number of different cover profiles can be used with a large number of combinations of seals and door leaves of different thicknesses, creating arrangements according to the invention in which, in particular, the joint between the web of the housing and the underside of the door leaf is covered. Thus, it is possible for the seal housing and the door leaf to be the same thickness, for the housing to be thicker than the door leaf, or for the door leaf to be thicker than the housing.

[0009] If the casing and door leaf are the same thickness, the casing is attached to the door leaf with its outer surfaces flush with the front and back of the door leaf. The first and second covers can then have the same cross-sectional profile. The two covers are then glued to the outer sides of the casing, mirroring each other.

[0010] If the casing and the door leaf are of different thicknesses, this difference in thickness can be compensated for by a strip of material, for example an insulating and / or sealing strip, in particular an EPDM strip. This can then be attached to one of the two outer sides of the casing. The casing can then be arranged flush with one side of the door leaf. The material strip can then be arranged on the opposite side. If the door leaf is thicker than the casing, the material strip can compensate for the difference in thickness between the casing and the door leaf. If, on the other hand, the casing is thicker, it may still be useful to glue such a strip of material to the casing.This can be particularly useful if it makes it possible to choose a profile for the cover on this side of the door that is glued to the material strip on the one hand and rests on the outside of the door leaf with an inward-projecting upper end of the profile on the other.

[0011] But even if the casing and the door leaf do not have different thicknesses, i.e. even if the casing and the door leaf have the same thickness, a strip of material can be provided.

[0012] According to the invention, the first and / or the second cover can be glued to the housing by means of an adhesive strip.

[0013] The first and / or second cover may have a recess on an inner side. The adhesive strip may be glued into the recess. The depth of the recess may correspond to the thickness of the adhesive strip. The material strip may also be glued into the recess.

[0014] The first cover and the second cover can have the same cross-sectional profile.

[0015] Further features and advantages of embodiments of the invention are described below with reference to the drawings. The same reference numerals are used for identical or similar parts and for parts with identical or similar functions. They show: Fig. 1 a side view of a first arrangement according to the invention with a first door leaf and a first automatic seal, Fig. 2 a side view of a second arrangement according to the invention with a second door leaf and the first automatic seal, Fig. 3 a side view of a third arrangement according to the invention with a third door leaf and a second automatic seal, Fig. 4 a side view of a fourth arrangement according to the invention with a fourth door leaf and the second automatic seal, Fig. 5 a side view of the first automatic seal and Fig. 6 a side view of the second automatic seal.

[0016] The seals 2 used in the illustrated inventive arrangements comprise a housing 21, a sealing strip 22, 23 with a retaining strip and a sealing element 23, a movement mechanism (not shown), a return spring (not shown), and a trigger 24. The sealing strip 22, 23 is connected to the housing 21 via the movement mechanism and can be moved either from a release position to a sealing position or vice versa upon actuation of the movement mechanism.

[0017] In the sealing position, the sealing strip 22, 23 is moved out of the housing and rests against a counter surface, such as a floor. In the release position, the sealing strip 22, 23 is lifted from the counter surface, allowing a door leaf to move freely relative to the counter surface.

[0018] The movement mechanism can be a movement mechanism with leaf springs or a scissor mechanism, as is known from the prior art and has also been disclosed in great variety by the applicant in particular. The movement mechanism can be actuated by a force introduced into the movement mechanism. To move the sealing strip 22, 23 from the release position into the sealing position, a force can be introduced via the trigger 24, which is connected to the movement mechanism. To move the sealing strip 22, 23 from the sealing position to the release position, the return spring, which is also connected to the movement mechanism or is even an integral part of the movement mechanism, introduces a force onto the movement mechanism. The return spring can be tensioned, in particular when the sealing strip 22, 23 moves from the release position into the sealing position, by the force introduced via the trigger 24.

[0019] In principle, it is also possible for a seal to be used in an arrangement according to the invention in which the force for moving the sealing strip 22, 23 is applied by a motor.

[0020] The seal housing is essentially U-shaped. It has two parallel legs and a web connecting the first ends of the legs. The web of the second seal provides an upwardly open channel, which could be used to attach the seal, in particular to a wooden or steel door leaf, as is known from prior art seals. No channel is provided in the web of the housing of the first seal.

[0021] The housings of the first seal and the second seal have different thicknesses D1 and D2. The housing of the second seal is thicker than the housing of the first seal.

[0022] The door leaves 1 are all-glass door leaves of different thicknesses d1, d2, d3, d4, where d1 < d2 < d3 < d4 and d1 is the thickness of the first door leaf, d2 is the thickness of the second door leaf, d3 is the thickness of the third door leaf and d4 is the thickness of the fourth door leaf.

[0023] Furthermore, for the first arrangement d1 ≈ D1, for the second arrangement d2 > D1, for the third arrangement d3 < D2 and for the fourth arrangement d4 > D3.

[0024] The arrangements also have adhesive strips 4 and material strips 5 made of EPDM.

[0025] The seals 2 are glued to the underside of the door leaf 1 by means of one of the adhesive strips 4. The adhesive strip 4 connects the outer side of the web of each housing 21 of one of the seals 2 to the underside of the door leaf 1. The seals 2 are positioned such that the outer side of the first leg of the housing, shown on the left in the figures, is flush with the outer side of the door leaf. Depending on the thickness of the door leaf 1 and the thickness of the attached seal 2, the outer side of the second leg is flush with the second outer side of the door leaf, as in the arrangement from the Fig. 1 the case, the outer side of the second leg jumps back behind the second outer side of the door leaf 1, as in the second and fourth arrangements, or the second outer side of the door leaf 1 jumps back behind the outer side of the second leg of the housing 21 of the seal 2.

[0026] In addition to the seals 2, the door leaves 1, the adhesive strips 4, and the material strips 5, the arrangements also include two covers 31, 32, 33 each, namely a first cover 31 and a second cover 31, 32, 33. Covers made of three different profiles are used for the four arrangements, so that there are three different variants 31, 32, 33 for the four arrangements shown.

[0027] Adhesive strips 4 are provided for attaching the seal 2 to the door leaf 1 and for attaching the covers 31, 32, 33 to the housing 21 of the seals 2. The EPDM material strips 5 fill the cavities between the covers 5 and the housing 21 of the seals 2. The EPDM material strips are easily compressible and can be used to fill cavities of various sizes.

[0028] A first variant 31 has an outer side that is curved at the upper end and tapers to a point with an inner side. At the lower end, the first variant protrudes slightly inward. On the inner side of the first variant 31 of the cover, a recess is provided into which the adhesive strip 4 is glued, with which this variant is adhered to the housing 21 of the seal 2.

[0029] The first variant 31 of the covers is used as the first cover in the four arrangements shown in the figures. It is glued to the outside of the first leg of the housing 21 of the seal 2 of the first, second, third, and fourth arrangements using an adhesive strip. The first cover slightly projects beyond the lower end of the first leg of the housing 21 and protrudes upwards over a joint between the door leaf 1 and the housing 21 of the seal 2, so that this joint is covered and not visible.

[0030] The first variant 31 is used in the second arrangement on the other side of the arrangement. For this purpose, it is glued by means of an adhesive strip 4 to a material strip 5 made of EPDM, which has a thickness corresponding to the extent of the projection of the thickness d2 of the door leaf 1 of the second arrangement over the thickness D1 of the housing 21 of the first seal 2. The material strip 5 extends over the entire height of the second leg of the housing 21 of the first seal. Together with the second outer surface of the door leaf of the second arrangement, an outer side of the material strip 5 forms a surface to which the first variant 31 forming the second cover of the second arrangement is glued.

[0031] The second variant 32 is bent inwards from a central flat area at an upper end and angled inwards at a lower end, with the upper end projecting more inwards over the central area than the lower angled end.

[0032] The second variant 32 is used as the second cover in the first arrangement. For this purpose, an adhesive strip 4 is first glued to the outside of the second leg of the housing 21 of the seal 2, to which a material strip 5 is then glued. The second variant of the profiles is then glued to this material strip 5 as the second cover.

[0033] The third variant 33 of the profiles is similar to the second variant 32. They differ essentially in that, starting from a central, flat area, the upper end is bent further inward than in the second variant 32, and that the lower end, which is also angled inward like the second variant 32, protrudes further inward and ends in a plane parallel to the central area, like the upper, inwardly bent end.

[0034] The third variant 33 is used as a second cover in the third and fourth variants. For this purpose, material strips 5 are first glued to the outer sides of the second legs of the housings 21 of the seals of the third and fourth arrangements using adhesive strips 4, to the outer sides of which the third variants 33 of the profiles are then glued. The thickness of the material strip of the second arrangement is selected such that the upper end is a small distance from the second outer side of the door leaf 1, whereas in the fourth arrangement the thickness of the material strip is selected such that the upper end rests against the second outer side of the door leaf 1.

[0035] The second covers also protrude upwards over a joint between the door leaf 1 and the housing 21 of the seal 2, so that this joint is also covered by the second outer side of the door leaf 1 and is not visible.
