SECTIONAL DOOR

Description

[0001] The invention relates to a sectional door with a door leaf which is movable along a path predetermined by a guide rail arrangement between a closed position, in which it is arranged approximately in a vertical plane, and an open position, in which it is preferably arranged overhead, in particular approximately in a horizontal plane, said door leaf comprising a plurality of door leaf elements arranged one behind the other in the direction of door leaf movement and articulated to one another with respect to hinge axes running perpendicular to the predetermined path, in which at least one door leaf element comprises a surrounding frame having a filling, such as a transparent pane arrangement, with a holding device designed to hold the filling and which, via a sealing device, bears against an outer boundary surface of the filling which, in the closed position, faces away from the space to be closed off with the door leaf.

[0002] Sectional doors are used to close garage and hall openings. They feature a door leaf that can be moved along a guide rail arrangement between an open and a closed position. The door leaf consists of a plurality of door leaf elements that can be pivoted relative to one another along hinge axes running perpendicular to the direction of movement. This door leaf design allows for opening and closing movements along the guide rail arrangement without pivoting the door leaf into the area facing away from the space to be closed, because the door leaf panels can be tilted relative to one another along an arcuate guide rail section.

[0003] The guide rails typically comprise a first guide rail section running linearly in the direction of gravity, a second guide rail section running linearly and essentially horizontally, and a curved guide rail section connecting the two linear guide rail sections. The horizontal guide rail section is typically arranged overhead, so that the sectional door can be arranged overhead in the open position, approximately in a horizontal plane, while in the closed position it is arranged approximately in a vertical plane. Corresponding guide rail arrangements can also be used for the sectional door according to the invention.

[0004] When designing sectional doors, care must be taken to ensure that, in addition to ensuring a secure opening closure, the door leaf also remains sufficiently stable in the open position. Furthermore, in many cases, the door leaf is also required to provide thermal separation between the space to be closed off by the door leaf and the outside. As is known, the panels of such door leaves can be designed as so-called sandwich constructions, in which an insulating foam core is sandwiched between two metal shells. Corresponding sectional door panels are described, for example, in EP 0370376. The disclosure content of this document with regard to the design of sectional door panels, in particular with regard to their edge profiles, is hereby expressly incorporated into this description.

[0005] The sandwich panels described above not only provide good burglar protection and satisfactory thermal insulation, but also effective privacy protection. In many cases, however, it is desirable for the sectional door leaf to also function as a window when closed. For this purpose, EP 0370376 proposes aluminum frame constructions with frames of the type described above.In the known frames, the frame members forming the frame can have an outer profile forming an outer side of the frame facing away from the space to be closed with the gate in the closed position and an inner profile forming an inner side of the frame facing the space to be closed with the gate in the closed position, wherein these profiles are spaced apart from one another in a direction extending perpendicular to the outer side and / or inner side and are connected to one another via a connecting device formed at least partially from thermally insulating material.

[0006] A panel (thermopane panel), for example, comprising two, three, or more transparent panes, can be inserted into such a frame. This panel typically rests on a retaining device, also known as a positioning bar of the outer profile, via a sealing arrangement and can be locked there using another retaining device that engages behind or underneath the panel.

[0007] To further improve thermal separation with the aid of corresponding frame constructions, EP 2666948 A1 proposes a further development in which a coupling device is arranged on the boundary surface of the connecting device between the outer and inner profiles facing the filling. This coupling device serves to establish a positive connection with a further holding device designed to hold the filling and resting against an inner boundary surface of the filling. This arrangement reduces a thermal bridge across the holding device designed to hold the filling. The disclosure content of EP 2666948 A1 ( Fig. 1 and 2 , Description Sections

[0027] to

[0040] ) regarding the design of the coupling and holding devices is hereby incorporated into this description by express reference.

[0008] However, when using the frames described above to manufacture sectional door elements, it has been shown that the thermal separation between the interior space to be closed off with the door leaf and the exterior space deteriorates with increasing service life.

[0009] Sectional doors according to the preamble of patent claim 1 are described in DE 60308908 T2.

[0010] Sectional doors with door leaf elements that have a frame surrounding a panel are described in EP 0787882 A2 and EP 2666948 A1. Window and door frames with drainage and / or ventilation slots or openings are described in DE 2930539 A1, GB 1210410 A, and DE 3308273 A1.

[0011] In view of these problems in the prior art, the invention is based on the object of providing a sectional door with thermal separation between the interior and exterior spaces, with which the desired thermal separation can be permanently ensured.

[0012] According to the invention, this object is achieved by a sectional door according to claim 1.

[0013] This invention is based on the realization that the observed reduction in thermal separation between the space to be closed off by the sectional door and the outside space is caused by moisture penetrating into a cavity between the sealing device, frame, and / or filling, despite the sealing device between the retaining device and the filling. It has been shown that the penetration of moisture into this cavity is unavoidable. The moisture collects in the cavity and forms a thermal bridge, which causes the observed deterioration in thermal separation. According to the invention, this deficiency is remedied by equipping the frame with a drainage device for draining liquids from the cavity between the sealing device, frame, and / or filling.It was recognized that a corresponding discharge device can be implemented without any significant impairment of the overall stability and the otherwise desired thermal separation, in order to permanently ensure the desired thermal separation.

[0014] The frame of door leaf elements of sectional doors is usually made from individual frame members, each designed as a hollow profile, with aluminum being the preferred material for manufacturing these hollow profiles. The drainage device provided according to the invention is characterized in that at least one lower frame member of the frame, which is arranged below the filling in the closed position, is designed at least partially as a hollow profile, and the drainage device has an opening in an upper wall of the hollow profile separating the cavity from a chamber of the hollow profile, which chamber preferably runs approximately parallel to the joint axes. Through this opening in the upper wall of the chamber of the hollow profile, moisture can drain from the cavity into a chamber of the hollow profile.If the hollow profile according to the teaching of EP 2666948 has an inner profile and an outer profile which are connected to each other via a connecting device made of thermally insulating material, it can be ensured in this way that the desired thermal separation is not significantly impaired by penetrating moisture.

[0015] Within the scope of the invention, however, it has proven particularly advantageous if the discharge device has a second opening in an outer wall facing away from the space to be closed off with the door leaf in the closed position and / or an inner wall facing towards the space to be closed off with the door leaf in the closed position and / or the lower wall of the chamber in the closed position, through which the moisture which initially entered the chamber through the cavity can be released from the chamber again and thus removed from the frame beam as a whole.

[0016] Within the scope of the invention, it is also contemplated that the inner wall, possibly together with other components of the lower frame beam, defines a receptacle for a projection on the upper edge of a door leaf element arranged below the lower frame beam in the closed position, based on the construction already known from EP 0370376 A1. In this case, the opening in the inner wall of the chamber opens into a slot formed between the projection and the inner wall and can run from there along an outer boundary surface of the projection.

[0017] If an opening is provided in an outer wall, the drainage of liquids from the chamber can be promoted if the lower wall of the chamber, in the closed position, slopes towards this opening formed in the outer wall.

[0018] The invention also contemplates the use of hollow profiles that, in order to increase the stability of the frame structure, have two, three, or more chambers separated from one another by corresponding partition walls. In such constructions, the lower frame member can have a second chamber arranged below the chamber in the closed position. The drainage device can then have an opening in the lower, upper, inner, and / or outer wall of the second chamber, which is connected to the chamber arranged above it via an opening in the wall separating this second chamber from the chamber arranged above it.

[0019] In order to increase the stability of the overall arrangement, a receiving element can be arranged between the filling and the lower frame member, which delimits the cavity together with the sealing device, the holding device and a wall of a chamber of the hollow profile.

[0020] In conventional doors in which a receptacle for a projection formed on the upper edge of a lower door leaf element is formed in the area of ​​a lower edge of an upper door leaf element for the purpose of finger pinching protection, a sealing element is usually provided for the purpose of thermal separation and to prevent the penetration of liquid and / or dust into the space to be closed off with the door leaf, which sealing element is arranged in the closed position between the lower frame member and the projection on the upper edge of the door leaf element arranged below.Within the scope of the invention, despite the provision of a corresponding sealing element in the sense of promoting the thermal separation, a further promotion of the thermal separation can be achieved particularly effectively by providing a drainage device if an opening in an inner wall of a chamber of the lower frame member is arranged in the closed position in the side of the sealing element facing away from the space to be closed with the door leaf, so that the drainage of liquid from the chamber is not hindered by the sealing element.

[0021] As can be seen from the introductory explanation of conventional frame constructions, the invention is used with particular advantage in sectional doors in which at least one frame member of the frame, preferably the lower frame member, particularly preferably all frame members of the frame, has an outer profile which, in the closed position, forms an outer side of the frame facing away from the space to be closed off with the door, and an inner profile which, in the closed position, forms an inner side of the frame facing the space to be closed off with the door, wherein the profiles are spaced apart from one another in a direction extending perpendicular to the outer side and / or inner side and are connected to one another via a connecting device formed at least partially from thermally insulating material, wherein the drainage device is provided in the outer profile.

[0022] The invention is explained below with reference to the drawing, to which reference is expressly made for all details essential to the invention and not further detailed in the description. The drawing shows: Fig. 1 a schematic representation of a transition between successive door leaf elements of a door according to the invention according to a first embodiment of the invention, Fig. 2 one of the Fig. 1 corresponding representation of a second embodiment of the invention, Fig. 3 one of the Fig. 1 corresponding representation according to a third embodiment of the invention, Fig.4 one of the Fig. 1 corresponding representation according to a fourth embodiment of the invention, Fig. 5 one of the Fig. 1 corresponding representation according to a fifth embodiment of the invention, and Fig. 6 one of the Fig. 1 corresponding representation according to a sixth embodiment of the invention.

[0023] The Fig. 1 The gate shown comprises a gate with gate leaf elements 100 and 200 arranged one above the other in the closed position, which are connected to one another in an articulated manner via a hinge 10, the hinge axis in the drawing running perpendicular to the plane of the paper and, during operation, perpendicular to a path predetermined by guide rails.

[0024] The door leaf elements 100 and 200 have a filling 110 or 210 surrounding frames, of which Fig. 1an upper frame member 120 of the lower door leaf element 100 and a lower frame member 220 of the upper door leaf element 200 are shown. The lower frame member 220 has a holding device 222, which rests against an outer boundary surface 212 of the filling 210 via a sealing device designed as a sealing strip 250. Furthermore, the lower frame member 220 of the upper door leaf element 200 is equipped with a further holding device 260, which rests against an inner boundary surface of the filling 210. A cavity, designated overall by 270, is formed between the holding device 222, the further holding device 260, the filling 210, and an upper wall of a chamber 224 of a frame member 220 designed as a hollow profile below the holding device 222. Moisture penetrating into the cavity 270 can drain into this chamber through an opening 225 in the upper wall of the chamber 224.The liquid entering the chamber 224 via the opening 225 can drain through an opening 223 in an outer wall of the chamber 224. The shape of the openings 225 and 223 is shown in . Fig. 1 indicated at A. The opening extends only over a small portion of the total length of the chamber 224 extending parallel to the joint axis. The lower wall of the chamber 224 slopes down towards the opening 223 in order to promote the drainage of liquid from the chamber 224.

[0025] The lower wall of the chamber 224, together with an inner wall of a chamber 226 arranged thereunder and an outer wall of a chamber 228 arranged thereunder and spaced from the chamber 226, defines a receptacle 280 in which a projection 130 is received on the upper edge of the upper frame member 120 of the lower door leaf element 100.

[0026] The Fig. 2The embodiment of the invention shown differs essentially from that shown in the Fig. 1 illustrated embodiment, that instead of the opening 223 in the outer wall of the chamber 224, an opening 223' is provided in the lower wall of the chamber 224 through which liquid can drain into the chamber 226. Liquid can drain from the chamber 226 through an opening 227 in the inner wall of the chamber 226.

[0027] The Fig. 3 The embodiment of the invention shown differs essentially from the embodiments shown in Fig. 1 and Fig. 2illustrated embodiments, that the lower frame member 220 of the frame 200 is designed in two parts with an outer profile 220a forming an outer side of the frame facing away from the space to be closed with the gate in the closed position, and an inner profile 220b forming an inner side of the frame facing the space to be closed with the gate in the closed position. The outer profile 220a is connected to the inner profile 220b via a connecting device 300 made of thermally insulating material. The further holding device is arranged on the connecting device 300. This construction is described in EP 2666948 A1. The content of this document is hereby incorporated into this description by express reference with regard to the construction of the inner profile, the outer profile, the connecting device and the holding device.

[0028] At the Fig. 3In the embodiment of the invention shown, a cavity 270 is formed between the holding device 222, the filling 210, and the lower frame member, designated overall by 220. Moisture can drain from this cavity 270 through an opening 225 in an upper wall of a chamber 224 of the outer profile 220a, which is designed as a hollow profile, into this chamber 224 and through an opening 227 in an inner wall of the chamber 224 into a slot formed between the projection 130 and the inner wall of the chamber 224.

[0029] The Fig. 4 The embodiment of the invention shown differs essentially from that shown in Fig. 3 illustrated embodiment, the filling 210 is supported on the lower frame member 220 via a support element 280. The cavity 270' is formed between the support element 280, the holding device 222 and the upper wall of the chamber 224.

[0030] In the Figures 5 to 8 In the embodiments of the invention shown, the filling 210' comprises three spaced-apart discs to improve thermal insulation.

[0031] Furthermore, the Figures 5 and 6 The constructions presented essentially correspond to the Figures 3 and 4explained constructions. However, the chamber in the profile 200a, which is designed as a hollow profile, is divided into two chambers 224a and 224b in order to increase the overall stability. From the cavity 270, liquid can first drain through an opening 225 in an upper wall of an upper chamber 224a into this upper chamber 224a, from which it can drain through an opening 225a in a wall separating the upper chamber 224a from a lower chamber 224b into the lower chamber 224b, from which it can in turn drain through an opening 227 in the inner wall of the lower chamber 227b into a slot 280 formed between the projection 130 on the upper edge of the lower door leaf element and the receptacle formed in the lower frame member 220 of the frame of the upper door leaf element. In the Figures 5 and 6In the closed position shown, a sealing element 400 is arranged within the slot. The opening 227 is arranged on the side of the sealing element 400 facing away from the space to be closed with the door leaf.

[0032] The Fig. 6 The embodiment of the invention shown differs essentially from that shown in the Fig. 5 explained embodiment, that the filling 210' rests on the lower frame member 220 via a support element 280.

[0033] The Figures 7 and 8 The embodiments of the invention shown differ essentially in the shape of the projection 130 at the upper edge of the lower door leaf element 100 and the shape of the receptacle formed by the lower frame beam 220 of the upper door leaf element 200 from the Figures 3 to 6 illustrated embodiments of the invention, wherein in the Figures 7 and 8illustrated embodiments correspond to the embodiments according to the Figures 3 and 4 only one chamber is provided in the outer profile 220a of the lower frame member.
