Description

The invention relates to a frame design as part of a panel element for a sectional door leaf, which consists of several panel elements that are hinged together. The sectional door leaf is guided in a movable manner in side guides. The frame formation consists of horizontal and vertical aluminum profile elements that are connected to each other, with the aluminum profile elements being provided with insulating bars that create a thermal separation between outside and inside a building.

The DE 10 2012 010 028 A1 relates to a frame arrangement for producing a frame surrounding a filling for a component, such as a sectional door panel, a door or the like, with an outer profile forming an outside of the frame and an inner profile forming an inside of the frame, the profiles in a preferably in in a direction extending perpendicular to the outside or inside and are connected to one another via a connecting device consisting at least partially of a thermally insulating material with at least one boundary surface facing the filling, with one for producing a positive connection on the boundary surface of the connecting device facing the filling with a coupling device designed to hold the filling is arranged.

An overhead door system having an overhead door panel with multiple horizontal sections movable between a vertical closed position and a horizontal, open or overhead position within a guide rail system provides the WO 2021/209536 A1 again. The sectional door leaf has an inner and an outer door surface.

The object of the invention is to create a frame design as part of a panel element for sectional doors, which ensures that the legal requirements for thermal insulation are met. Such a frame design should be easy to produce, while at the same time there must be sufficient longitudinal shear strength. It is important to ensure that such an assembly of the frame structure can be carried out easily.

The object of the invention is achieved by the features of claim 1. The subsequent subclaims reflect a further embodiment of the idea according to the invention.

Aluminum profile elements are used which have an outer hollow section and an inner hollow section in cross section, which are separated from one another. The outer hollow section is used to ensure thermal insulation. This hollow section is formed by an outer outer leg of the aluminum profile element by insulating webs on the top and bottom, which are connected to an inner intermediate web running in the direction of the aluminum profile element. This creates an external hollow section that ensures that the necessary thermal bridge, i.e. separation between the inside and outside of a building, is guaranteed. The second, inner hollow section is directed towards the interior of the building and is formed by the intermediate web and aluminum profile element sections connected to it towards the interior of the building. The inner leg of the aluminum profile element can be connected directly or indirectly to the insulating intermediate webs. This design of the aluminum profile elements applies to both horizontal and vertical profile versions.

Because the frame formation is intended as part of a panel element for sectional door leaves, it must be ensured that the frame formation is so stable at the top and bottom that the same sealing and cooperating function is ensured with a conventional panel element of the same design arranged above or below it. For this purpose, such frame designs have a convex shape on their upper side and a concave shape on their underside. Such a construction ensures that the interaction of a frame formation with panel elements arranged above or below works without any problems. With such an embodiment, the same fittings can also be used between a frame formation and a closed panel element in order to be able to carry out a hinged movement with one another.

The structural design of the aluminum profile elements into an inner and an outer hollow section in cross section results in a very effective division into an outer hollow section that serves exclusively for thermal insulation and an inner hollow section that also contributes to thermal insulation, but also to connect corner versions of the aluminum profile elements in one Joint design with one another, i.e. there are no miter cuts, is used.

The outer hollow section has an outer leg which has no further reinforcing elements or chambers or projections formed on the inside. The intermediate bridge points does not necessarily have a straight course between the inner and outer hollow sections, but can also take on other shapes. The outer hollow section is closed off on the top and bottom by the insulating webs. For the connection between the outer leg and the intermediate web with the insulating webs, these have fastening sections at the end, which make it possible to permanently attach the insulating webs in a different shape to aluminum profile elements in a manufacturing process. For this purpose, the insulating webs preferably have approximately trapezoidal clamping sections at the end, which are permanently pressed with the sections of the aluminum profile elements in the manufacturing process. In order to achieve great strength and at the same time rigidity in the insulating bars used, polymers are used as a material. Polymers are ideally suited to forming such insulating bars. The polymers are characterized as a tough material with high strength and rigidity, which can also be used in a wide temperature range from around -30°C to over +100°C. This is particularly important for sectional doors with a frame design, as very high temperatures are possible when the outer legs are exposed to sunlight, but also very low temperatures in winter. The family of linear polymers with amide compounds is particularly suitable for this.

In order to achieve even greater dimensional stability and resilience of the insulating bars, the linear polymers can be provided with additives. Elongated glass fibers in the form of glass fiber-reinforced polyamides have proven to be particularly useful in the design and execution of insulating bars. The possibility of rational production of rod materials for the insulating bars made of polyamide can be carried out cost-effectively. The complexity of the geometry of the insulating bars with and without fiber-reinforced polyamides results in enormous rigidity and at the same time great elasticity. Water absorption by the insulating webs cannot generally be avoided, but can be described as minimal and does not affect the dimensional stability of the frame design of the aluminum profile elements in any way.

The inner hollow section of the aluminum profile elements can in principle also contribute to the thermal insulation of the profile formation as a whole. However, this inner hollow section has the particular task of facilitating the connection between vertical and horizontal profile sections to form the frame. The inner hollow section has on the inside a substantially straight inner leg and the connecting sections connected thereto, which are, for example, directly or indirectly connected to the intermediate web or can enable the inclusion of retaining strips for holding plate-shaped elements. Furthermore, connecting screws can be inserted into a profile to be connected as a butt joint. There are holes for this purpose through which the connection between two aluminum profile elements at an angle of 90° to one another can be carried out using reinforced connection bearings. This enables a simple and permanent, cost-effective connection of two profile sections.

A receiving space for the retaining strips is formed via the connecting section between the inner leg and the intermediate web. For example, such a retaining strip can be made of plastic or light metal for weight reasons. Such a holding strip has a cavity enclosed on all sides by walls, which thereby makes the holding strip as a whole torsion-resistant. For assembly and disassembly in the event of damage to the fillings of the fields of vision, it is necessary that the plate-shaped elements can be replaced quickly and easily. If the retaining strip is made of plastic, an impact-resistant plastic with a very high Shore hardness is preferably used. The enclosed cavity has a base on the underside from which a protruding, spread-out hook extends. The holding strip engages with this hook in a recess in the aluminum profile element, which is part of the inner hollow section. With a lower support side, which is part of the base and lies in the area in front of the hook, the retaining strip rests on part of the aluminum profile element. The design of the hook is characterized by two different sections. A high prestress should be generated on an outside of the retaining strip relative to the plate-shaped element. It is necessary that only materials that are not subject to embrittlement are used for the retaining strip.

It is also possible for the side with which the retaining strip is positioned against the plate-shaped element to be provided with sealing lips. Such a construction can be carried out in production using a two-component technology. Different hardnesses of a retaining strip are produced in an injection molding process in one operation, but with strictly separated component areas. By using such additional sealing lips, a further very good seal can be achieved between the retaining strip and the plate-shaped element. The combination of thermoplastic plus elastomer, ie plastic and rubber, means that complex assembly work on the frame formation can be reduced Avoid inserting the plate-shaped element to ensure sufficient sealing.

By separating the cross section of the aluminum profile element into an outer and an inner hollow section, the greatest possible thermal insulation is achieved because the outer hollow section is only used for thermal insulation. In the EP 2 666 948 A1 The opening of the insulating webs is carried out via connections of vertical and horizontal hollow sections, which can no longer guarantee effective thermal insulation.

A sectional door leaf in a partial sectional view is shown in the 1 shown in a perspective view with a horizontal profile 24 and a horizontal profile 23 arranged underneath. This schematic representation shows the interaction of two panel elements in frame formations for a sectional door leaf. These frame designs can consist of one or more divided fields that are filled with replaceable panes 45. Such disks 45 can be used as plate-shaped elements in a transparent or opaque design. Such panes 45 hold their position within the frame formation by replaceable retaining strips 1 that are attached to the inside of the building. Since these frame formations are functionally equivalent to the known panel elements in the closed state of the sectional door leaf, it is necessary that such frame formations are installed on both the upper and lower sides lower horizontal sections in the closed position of the sectional door leaf are designed to overlap in the same design. For this purpose, for example, the horizontal profile 23 has a convex design on the top and the corresponding horizontal profile 24 shown above has a concave area, with the two aluminum profile elements 23 and 24 virtually interlocking in this position. To seal the two horizontal profiles 23 and 24 from one another, a sealing element 33 is present in the profile 24, for example; other sealing options are also possible. This sealing element 33 performs a sealing function against moisture and wind loads, etc. to the interior of the building in the closed position of the sectional door leaf, ie when the two panel elements 23, 24 are one above the other.

The panel elements usually consist of outer and inner sheet metal elements spaced apart by an insulating foam.

The cross section of the horizontal profile 23 is divided into two separate cavities. This means there is an outer cavity and an inner cavity. The outer cavity is limited to the outside of the building 26 by an outer leg 28 as part of the frame formation. Insulating webs 22 are arranged on the top and bottom between the outer leg 28 and an intermediate web 25, so that there is a closed outer cavity. There are no chambers or other self-contained additional cavities within this enclosed, outer cavity. The insulating webs 22 are made of a polyamide and each have clamping sections 53 at their lateral ends, which were connected in a non-positive and positive manner to the outer leg 28 made of aluminum and the intermediate web 25 made of aluminum in a manufacturing process. The inner cavity, which faces the interior of the building, has an inner leg 29 as part of the frame formation, which has a profile offset 2 on the top, which merges into the intermediate web 25 in an upper end region. The lower end of the inner cavity between the intermediate web 25 and the inner profile is formed by a connecting section 61 with a receiving section 16 for a retaining strip 1. This lower connecting section 61 has a thickened cross-section compared to the other aluminum profile designs with an additional recess in the form of a connecting bearing for connecting the horizontal profiles 23 with a vertical profile 27 in a joint design. The inner cavity has molded material thickenings in the area in which there are holes 31 on the bottom for the butt connection with the vertical profile 27, which are used to connect the vertical profiles 27 via connecting elements 48. As a result, the inner cavity essentially becomes a mounting section with insulating properties and the outer cavity becomes an exclusive insulating section in the frame formation.

To form the upper convex end shape of the horizontal profile 23, a profile offset can be present on the upper side of the outer leg 28 before the insulating web 22 begins. The upper end of the horizontal profile 23 is therefore provided with a protruding, convex end.

In the closed position of the sectional door leaf, an upper panel element interacts with the horizontal profile 23, which is in the form of a frame and contains the sealing element 33 for the sealing function against the insulating web 22, which is embedded in a seal receptacle 36 of the horizontal profile 24. In order to ensure the sealing function of the two panel elements in the frame formation with one another, there are lugs on the side of the horizontal profile 24 as a continuation of an inner leg 57 and the outer leg 30, which protrude against the profile attachments with a play.

The horizontal profile 24, like the horizontal profile 23, is also equipped with an outer and inner cavity in cross section. The outer cavity is formed by the outer leg 30 as part of a frame formation in connection with the intermediate web 56 spaced apart by the insulating webs 22. The inner cavity has the bore 31, through which the connection bearing 32, which is also formed here, is accessible in order to connect the horizontal profile 24 with a vertical profile 27 via a butt connection formed at an angle of 90 °. In the horizontal profile 24 there is also a receiving section 16 for the holding strip 10. In order to carry out the butt connection between the horizontal profile 24 and the vertical profile 27, the profile thickening in the connecting section 61 is also present here, aligned with the bore 31, as a reinforcement, which is used for the connecting bearing 32, so that the horizontal profile 24 does not warp if the connection between a vertical profile 27 and horizontal profile 24 is carried out. At the same time, the connecting section 61 strengthens the horizontal profiles 23, 24 without increasing the weight of the aluminum profile elements.

The inner cavity is designed differently in the horizontal profile 24 than in the horizontal profile 23. This is because the panel elements of the sectional door leaf are intended to achieve a sealing function between two adjacent panel elements in the closed position of the door. For this purpose, there is an additional chamber at the bottom of the inner cavity, which ends in a rounding 39. Due to the rounding 39, the existing sealing element 33, which is attached to the horizontal profile 24, is pressed against the convex profile attachment 2 of the underlying panel element with the horizontal profile 23. To the outside, the projecting end leg 58 of the outer leg of the horizontal profile 24 is carried out relative to the profile offset 2. As a result, a substantially concave shape is formed on the underside of the horizontal profile 24, into which the convex end region of the horizontal profile 23 is immersed.

The butt joint is in the 1 not shown. For execution between the vertical profile 27 and the horizontal profile 24, a substantially flat surface is created, for example, on the outside 26 of the sectional door leaf. For this purpose, for example, the horizontal profile 24 has a cantilevered outer leg 30, the end of which dips into a shoulder 34 incorporated into the vertical profile 27.

In the 2 Only the horizontal profiles 23 and 24 were shown with the retaining strips 1 inserted. The retaining strip 1 is inserted into the two profiles 23 and 24 via a bend 12. From this illustration it is clear in the horizontal profile 24 that above the bore 31 there is a smaller bore 38 in the reinforced connecting section 61. Thus, the connection bearing 32 can be provided with a continuous guide 59, according to that shown in FIGS 9 and 10 connecting element 48 shown can be used. The lateral guide 59 not only makes inserting the connecting element 48 much easier, but it also ensures that the profiles 23 and 24 do not warp.

To place the panes 45 or the like on the outside of the building 26, sealing receptacles 35 are present in the cantilevered leg designs of the horizontal profiles 23 and 24 and at the end of the vertical profiles.

The horizontal profile 24 after 3 , in a cross-sectional view, shows the connection bearing 32 with the reinforced material design in the connection section 61 with the frame support 15. The construction makes it possible for a permanent, secure, non-positive and positive connection to be provided by the butt connection between the vertical profile 27 and the horizontal profiles 23 and 24, without the need to use additional components. The cross-sectional reinforcement in the connecting section 61 with the guide 59 represents a simple connection and no further components need to be provided for stabilization when executing a frame corner connection, which would also lead to an increase in weight.

By showing the detail of the detail 3 will be in the 4 illustrates how the holding strip 1 can be inserted within the open receiving space 16 with the protruding hook 12 and placed against the plate-shaped element 45. There is the 4 a first preferred embodiment of a retaining strip 1 again. The holding strip 1 has a cavity 6 that is closed on all sides and is enclosed on the outside of the door leaf by an outer wall 4 and on the inside by a contact side 3, as well as an intermediate leg 5 on the top and a base 7 on the bottom. When installed, the contact side 3 leads to contact with the disk 45. The contact side 3 must apply the necessary pressure against the disk 45 or another plate-shaped element so that no water can penetrate from the outside between the contact side 3 and the disk 45. This can be achieved in particular by making the holding strip 1 from an impact-resistant plastic with a high Shore hardness, which nevertheless ensures a high contact pressure and thus large adhesion forces on the pane 45. However, it is also possible to produce the retaining strip 1 from another material, such as aluminum.

The base 7 of the holding bar 1 consists of a substantially straight support side 9, the adjoining hook 12 and an adjoining side with a bevel 8, which ends in an outer support point 11. The support side 9 and the support point 11 are at the same height level. The bevel 8, starting from the support point 11, is essentially in a range of 1° to 10°. The hook 12 is divided into a first section 10 and a second section 60. The first section 10 is set at an angle between 91° and 110° relative to the essentially straight support side 9. Following this first section 10, the second section 12 is again beveled towards the support side 6, with this angle, starting from the first section 10, being approximately between 40° and 50°. At the end of the second section 12 there is a projecting contact point 13. The section 10 and the bend 60 of the hook 12 dip into the receiving section 16. The support side 9 rests on the frame support 15 of the profiles 23, 24, 27 of the frame training. At the same time, the support point 11 has further contact with the frame support 15. While the support point 11 is in contact with the leg 20, the section 10 of the hook 12 is laterally in contact with a counter bearing 19 of the frame formation in the receiving section 16. Due to the inclination of the bend 60 of the hook 12, it comes into contact with an inner wall 17 at the end within the receiving section 16 on a contact wall 18 via the contact point 13. This type of construction ensures that the mounting strip 1 with the contact areas is safer and more durable Support can be awarded. The frame formation has a frame profile outside 14 on the outside, which is essentially aligned with the outer wall 4 of the retaining strip 1 after the mounting strip 1 has been used.

In the 5 a further preferred embodiment of the mounting strip 1 is shown. In this embodiment, additional sealing lips 21 are formed on the contact side 3. These sealing lips 21 have a lower Shore hardness than the retaining strip itself. This means that the two components of the retaining strip 1 can be manufactured in one operation using a 2K spraying process, so that the contact side 3 is made of a thermoplastic and the sealing lips are made of an elastomer can.

In another excerpt from 9 The design of the butt joint between the vertical profile 27 and one of the horizontal profiles 23 or 24 will be discussed again. This representation makes it clear that in the area in which the connecting element 48 dips into the connecting section 61, there is a substantially greatly enlarged profile formation compared to the other walls of the aluminum profile elements. This thickening of the profile element puts the connection bearing 32 in a position such that tightening of the connection element 48 does not result in any distortion of one of the aluminum profile elements used.

An exemplary preferred embodiment of a vertical profile 27 is given by: 7 again. In this embodiment, an outer leg 40 is shown, which has a projecting area for a seal receptacle 35 at one end. Here too there is an inner and an outer one Cavity present. The outer cavity is separated from the inner cavity by an intermediate web 41. The screw channels only have the functional task of dealing with the butt joint. Here too, the outer leg 40 is distanced from the intermediate web 41 by insulating webs 22. Reference is once again made to the non-positive and positive connection of the clamping sections 53 of the insulating webs 22 with the aluminum profile elements. The insulating webs 22 here have a substantially straight distance 52, which is followed by offsets 54 at each end. The offsets 54 then merge into the clamping sections 53. On the inside of the building there is also the profile training 7 an inner cavity is present, which is formed on one side with the receiving section 16 for the holding strip 1.

In the 8th a further, modified preferred embodiment of a vertical profile 37 is reproduced. The vertical profile 37 is essentially formed by an outer leg 46 and insulating webs 22 connected to it, which are then connected at the end to an intermediate web 56. Such a vertical profile 37 is used when the frame formation consists of several, ie self-contained, fields for panes 45. This is also evident from the fact that the inner cavity is closed on the outside by an inner leg 47. The inner leg 47 has the receiving sections 16 for the holding strips 1 and thus for the use of disks 45 on its two vertical sections. The outer leg 46 has projecting ends on both sides, each with a seal receptacle 35.

The 6 shows an upper end of a sectional door leaf. The execution is carried out according to 6 used in such a way that a seal receptacle 36 on the top with a sealing foot 44 on a projecting upper seal 43 can be carried out. Here too, an intermediate wall 55 separates the outer and inner cavity from each other.

The lower section of a sectional door leaf, which has been provided with a frame, for example, is shown 10 , whereby a bottom end profile 49 is used here. This bottom end profile 49 has a much higher level of training than the other horizontally used profiles 23 and 24. As a result, the outer cavity is divided by several insulating webs 22 in order to achieve good thermal insulation in addition to greater strength for the floor end profile 49. The floor seal 51 with its sealing foot 42 is inserted within a seal receptacle 50, which forms the lower end of a contact area on the building side.
