Description

[0001] The invention relates to a frame system for an insect and / or pollen protection screen, according to the preamble of claim 1.

[0002] To protect building openings, such as windows or doors (balcony or patio doors), insect, particle, or pollen screens can be mounted as frame systems. These screens are inserted into a profile frame, which in turn should cover the building opening as completely as possible. The greatest possible flexibility in adapting to different opening sizes is desirable.

[0003] Furthermore, a straightforward frame assembly and easy insertion of the protective mesh or fabric into the profile frame are desirable. Disassembly should also be possible, particularly for replacing individual parts. Secure mounting of the profile frame covered with the protective mesh (mesh or fabric) at its intended location, especially on a door or window, should also be ensured. Finally, the overall system should be as flexible as possible to allow for adaptation to varying on-site installation conditions.

[0004] A protective grille for mounting on a door frame is known, for example, from EP 2 392 761 A1. The known protective grille comprises a grille frame made of profile rails, which is positioned in front of the door frame and has vertical and horizontal profiles connected to each other by corner connectors. The profile rails are designed as hollow chamber profiles. A receiving channel open towards the door frame serves to receive a keder (seal) to which the mesh (mesh insert) is attached. The mesh covers the frame opening of the grille frame, and thus the door opening, in a way that allows air to pass through and protects against the ingress of foreign objects.

[0005] In this type of safety gate, a further vertical profile is typically arranged as a crossbar at half the height of the vertical profiles. The crossbar is also connected to the vertical profiles at the corners by means of corner connectors, with at least one such corner connector serving as a door handle for easier opening and closing of the safety gate.

[0006] The corner connector has a substantially T-shaped form, with the horizontal leg of the T engaging as a joint in a joining chamber of the vertical profiles and the vertical leg of the T engaging as a joint in a joining chamber of the cross member. The door handle is designed specifically by means of a widened cover collar on the corner connector, which, when installed, extends beyond the facing end faces of the profile strips on the front of the profile frame. This ensures that the tensioning of the mesh on the frame side is not adversely affected.

[0007] Such door handles often exhibit reduced stability, as their installation depth in the profile rails is limited to the length of the footplates. Furthermore, these types of door handles typically offer reduced user comfort, since the gripping surface of the cover collar is only a few centimeters from the protective grille, making it difficult for users to grasp the handle.

[0008] From DE 10 2011 051 303 A1, a swing-gate handle is known as a door handle for, for example, an insect screen door. The known door handle comprises a frame part prepared for positive engagement with the edge of an opening in a door frame, to which a swing-gate part is hinged, at least partially covering the clear opening of the swing-gate handle in the door leaf. A spring is provided to hold the swing-gate part against a spring force in the clear opening, so that the swing-gate part can be swung open against the spring force, allowing access through the clear opening. The spring is supported on one side by the swing-gate part and on the other side directly by the frame part or via a groove-shaped piece for bearing in a groove in the edge of the opening.

[0009] The familiar door handle is roughly rectangular and can be inserted into a special, approximately U-shaped, retaining contour in the door leaf, thus securing the frame section stably on three sides. This design is particularly disadvantageous in a modular frame system of the type mentioned earlier. The necessary provision of a special retaining contour in the area of ​​the crossbar for the door handle negatively reduces the flexibility of the frame system.

[0010] From EP 2 392 761 A1, a frame system for an insect and / or pollen screen is known, comprising a number of longitudinal and transverse profiles mounted perpendicular to each other in frame corner areas. The longitudinal and transverse profiles are designed as hollow profiles with an angled inner profile contour and with at least one receiving chamber extending in the longitudinal direction of the profile and accessible via a longitudinal slot in the profile. This chamber is designed to receive a keder-like retaining element for attaching a mesh fabric to the frame. The longitudinal and / or transverse profile accommodates connecting elements that have a fixing shaft adapted to the respective inner profile contour and at least one through-opening or screw-in opening. At a corner connection between the longitudinal and transverse profiles, a screw element is screwed through a side opening in the longitudinal profile into the screw-in opening of the connecting element held by the transverse profile.

[0011] The invention is therefore based on the objective of providing a frame system and in particular a door handle for it, which is particularly easy to assemble, stable and as visually appealing as possible, while avoiding the aforementioned disadvantages.

[0012] This problem is solved according to the invention by the features of claim 1. Advantageous embodiments and further developments are the subject of the dependent claims.

[0013] For this purpose, a frame system for an insect and / or pollen screen door comprises a number of longitudinal and transverse profiles, which are mounted perpendicular to each other in frame corner areas by means of corner connectors. The longitudinal and transverse profiles are designed as hollow profiles with at least one receiving chamber extending in the profile direction and accessible via a longitudinal slot in the profile for receiving a retaining element, in particular a bead-like retaining element, for attaching a mesh fabric to the frame, as well as with a joining chamber parallel to the receiving chamber. A connecting element serves to attach a single transverse profile in a corner area along the longitudinal profile with a first joining leg that can be screwed to it and with a second joining leg that is molded onto this first leg and can be inserted into the joining chamber of the transverse profile.In its assembled state, a handle section spanning the corner area is screwed on one side to a first T-nut located in the receiving chamber of the transverse profile and on the other side to a second T-nut located in the receiving chamber of the longitudinal profile.

[0014] The handle is secured using T-nuts inserted into the mounting chambers, enabling stable mounting of the handle to the longitudinal and transverse profiles. Furthermore, this allows for a shallow installation depth of the handle within the profile frame.

[0015] The handle is essentially arranged in the same plane as the mesh fabric. This eliminates the disadvantageous need to grip the handle behind the mesh fabric, making the handle easy for people to use.

[0016] In a typical embodiment, the frame system is designed according to a modular principle. This means that, for example, the profile strips and the mesh are manufactured and supplied in various standard sizes, allowing a consumer to assemble a customized frame system for different building openings. This easily and advantageously increases the flexibility of the frame system, thus enabling adaptation to varying on-site installation conditions. For this purpose, the profile strips are designed to be cut to length. This further increases the flexibility of the device and simplifies its use in older buildings with variable opening dimensions.

[0017] For mounting the insect and / or pollen screen door, two T-shaped connecting elements for coupling the individual cross profiles and a handle are additionally provided. Furthermore, at least two, preferably three, hinges (including groove and screw elements) are provided for the secure and reliable attachment and pivoting of the frame system, particularly to a door frame. A footboard is also preferably provided as a bottom-side cross profile.

[0018] The profile strips are preferably cuttable metal profiles, for example made of aluminum. Their cross-section is preferably essentially rectangular, although square versions are also conceivable. The front of the profile strips is essentially smooth, resulting in a visually appealing frame system. A number of profile slots are arranged on the back, allowing keder-like functional elements to be inserted and / or pressed into the respective receiving chambers of the hollow profile.

[0019] The single cross profile, which is positioned along the longitudinal profile, essentially serves as a cross brace for the frame system during assembly. This effectively avoids the risk of the frame system twisting, which can sometimes cause the corner connections to loosen.

[0020] For the corner connection of the longitudinal profiles to the individual transverse profile, a connecting element, preferably a one-piece connector, is provided as a corner connector. For this purpose, the transverse profile receives the connecting element at its end face, preferably in a form-fitting and suitablely force-fit manner, with the second connecting leg expediently having an outer contour adapted to the inner contour of the profile. In a corner connection of the longitudinal profile to the transverse profile, at least one screw element is screwed to the first connecting leg, which is essentially T-nut-like, in the longitudinal profile via a screw-in opening in the connecting element received by the transverse profile.

[0021] In a particularly advantageous embodiment, the handle is essentially triangular with an adjacent side and an opposite side, the adjacent side being oriented along the transverse profile and the opposite side along the longitudinal profile. This results in a stable design for the handle element, which thus serves as an additional stabilizing element, particularly in the corner area of ​​the frame system.

[0022] Preferably, the triangular handle is approximately right-angled. In particular, the angle between the adjacent and opposite sides is preferably 90°. In a suitable embodiment, the angles between the hypotenuse and adjacent sides, as well as between the hypotenuse and opposite sides, are equal and approximately 45°. This allows the handle to be easily positioned in the corner area between the longitudinal profile and the individual transverse profile.

[0023] The adjacent side extends perpendicular to the opposite side and thus, in the installed state, in the longitudinal direction of the profile, for example, in the direction of the longitudinally arranged longitudinal profile, which runs approximately vertically on a door when installed. The opposite side extends essentially transversely along the single, approximately horizontally arranged transverse profile, so that the longitudinal and transverse profiles are at least approximately perpendicular to each other and the handle part fits snugly against both the adjacent and opposite sides. This ensures an improved overall visual appearance of the handle part and frame system.

[0024] In a suitable design, the first T-nut extends essentially over the entire length of the adjacent side, and the second T-nut extends essentially over the entire length of the opposite side. This enables a particularly stable and reliable mounting of the handle part in the frame system.

[0025] The T-nuts are positively and preferably force-fitted within the receiving chambers, the T-nuts expediently having an outer contour adapted to the inner profile of the receiving chamber. The T-nuts preferably have a number of threaded bores, which are preferably accessible in the installed state by means of a longitudinal slot in the profile of the receiving chamber.

[0026] The handle preferably has a number of recesses which are large enough for the shank of a screw element, yet small enough for the head of the screw element. In this way, the handle can be easily and reliably screwed to the T-nuts, while maintaining a shallow installation depth.

[0027] In an advantageous embodiment, the handle part comprises a rigid handle frame screwed to the T-nuts and a handle element pivotally coupled to it. In a suitable embodiment, the handle frame is approximately triangular and firmly screwed to the T-nuts in the corner region of the frame system. In a suitable embodiment, the handle element and the handle frame interact approximately in the manner of a hinged flap handle.

[0028] In a suitable embodiment, the handle frame has mounting surfaces, particularly on the profile strip side, for screwing it to the T-nuts embedded in the longitudinal or transverse profile. In an equally suitable embodiment, the handle frame has a substantially trapezoidal recess in which the similarly substantially trapezoidal handle element is inserted. Preferably, the base direction of the trapezoidal recess or of the handle element is substantially parallel to the orientation of the hypotenuse side of the handle part / handle frame.

[0029] The handle frame is, in particular, a triangular piece of metal with screw plates molded onto the front and opposite sides, allowing the handle frame to be screwed to the T-nuts. The handle element is also made of metal, preferably the same material as the handle frame and the profile strips, resulting in a visually appealing frame system.

[0030] In a preferred embodiment, the handle element lies in the same plane as the handle frame when the insect and / or pollen screen door is closed. When the insect and / or pollen screen door is opened, the handle element pivots essentially perpendicular to the handle frame. In this embodiment, the handle element, which pivots outwards, i.e., towards a person opening the door, is designed as a door handle. This door handle provides additional leverage to make opening and closing the frame system easier. Preferably, in this embodiment, the handle element is ergonomically shaped so that it can be easily and comfortably grasped by a person.

[0031] Alternatively, it is also conceivable that the handle element is an inwardly pivoting cover plate, whereby to open the insect and / or pollen screen door, the handle element pivots inwards and the rigid handle frame is gripped from behind. This increases, for example, the service life of the handle component, as the comparatively large forces exerted when opening the door are transferred to the stable frame. This also makes it possible to design the pivoting handle element for lower mechanical loads, thus advantageously reducing manufacturing costs.

[0032] In a particularly advantageous embodiment, a cylindrical support element is provided which rests on a wedge-shaped support surface of the handle frame on the hypotenuse side of the handle element, wherein, when the handle element is pivoted, the support element and the support surface interact like a hinge joint. This results in a particularly simple and cost-effective design of the handle part.

[0033] In a particularly preferred embodiment, the handle frame on the one hand and the handle element on the other have rectangular magnetic elements facing each other with opposite magnetic polarity. The dimensions and / or material composition of the magnetic elements are specifically adapted such that the attractive force acting between them is strong enough to keep the handle frame and handle element closed, yet weak enough that pivoting the handle element during opening is not adversely affected. This advantageously and simply avoids, for example, the problem of the handle element being uncontrollably pivoted out of the handle frame by wind, thereby causing undesirable noises (rattling or the like).

[0034] In a suitable embodiment, the magnetic elements are seated in corresponding hollow-profile-like retaining contours of the handle frame and the handle element during assembly. This ensures particularly simple and reliable fastening of the magnetic elements during assembly. Preferably, the T-nut-like magnetic elements are positively and, suitablely, frictionally engaged in the retaining contours, with the magnetic elements expediently having an outer contour adapted to the inner profile of the retaining contour. Additionally or alternatively, in an advantageous embodiment, the magnetic elements have threaded bores for screws, with which the magnetic elements can be screwed or clamped into the retaining contour, similar to the T-nuts in the longitudinal and transverse profiles.

[0035] In a particularly advantageous embodiment, the mesh fabric is attached to the handle, handle element, and / or handle frame in the corner area. Due to the handle's placement in the corner, the handle and the mesh fabric lie essentially in the same plane when installed. Attaching the mesh fabric to the handle, handle element, or handle frame ensures that the frame system reliably protects against the unwanted ingress of insects and / or pollen. Preferably, the mesh fabric is attached to the handle, handle element, and / or handle frame along essentially the entire length of the hypotenuse side when installed. In another embodiment, it is conceivable, for example, that the handle frame—similar to the profile strips—has a receiving chamber for the retaining element used to attach the mesh fabric to the frame.

[0036] In a preferred embodiment, the handle frame has an upper and a lower cover plate, wherein the mesh fabric is clamped between the upper and lower cover plates during assembly. In a particularly advantageous further development, the lower cover plate of the handle frame has a clamping structure with a number of rib-like projections and recesses. The rib-like clamping structure is arranged, in particular, along the hypotenuse side, i.e., the side of the handle not in contact with the profile strips. The clamping structure ensures a particularly reliable clamping of the mesh fabric to the handle, so that the mesh fabric remains securely connected to the frame system, even during a storm.

[0037] An embodiment of the invention is explained in more detail below with reference to a drawing. The drawing shows: Fig. 1 in a rear view a frame system mounted as an insect screen door made of transversely and longitudinally arranged profile strips, which are connected in the corner areas by means of corner connectors, as well as a clamped mesh fabric as insect or pollen protection and a door handle, Fig. 2.

[0038] Corresponding parts and sizes are always marked with the same reference symbols in all figures.

[0039] The Fig. Figure 1 shows a rear view of a frame system 2 mounted as an insect or pollen screen door, consisting of longitudinal profiles 4 and transverse profiles 6, which are mounted perpendicular to each other in the frame corner areas. For this purpose, a (horizontally extending) transverse profile 6 adapted to the desired door dimensions of a building door opening is required in the Fig. The left and right upper frame corners are each stably connected to a (vertically running) longitudinal profile 4 by means of a corner connector 8. A building door opening refers in particular to a balcony, patio or front door.

[0040] Approximately in the middle of the frame system 2, another transverse profile 6 is connected to the two longitudinal profiles 4 via essentially T-shaped connecting elements 10. The longitudinal profiles 4 are further connected to each other at the underside of the frame system 2 by means of a special transverse profile, in particular designed as a tread cross profile 12, in stable corner connections using connecting elements 10. Of the connecting elements 10 of the lower corner connections, only one is shown in the figures with a reference numeral as an example.

[0041] The longitudinal profiles 4 and transverse profiles 6 are essentially identical aluminum profile strips with a hollow profile (not shown in detail), differing only in their cut dimensions and mounting orientation. The tread cross profile 12 is approximately twice as wide as the transverse profile 6 and is connected to the longitudinal profiles 4 at its corners via four connecting elements 10.

[0042] On the rear surface of the frame system in its assembled state, a mesh fabric 14 is mounted on the transverse and longitudinal profiles 6, 4 to provide insect protection, pollen protection, or generally particle protection. The mesh fabric 14 is attached by means of keder-like, preferably flexible clamping strips, which can be pressed into receiving chambers 16a on the rear of the profile or frame, slotted in the longitudinal direction of the profile, i.e., facing the inside of the frame, during assembly.

[0043] The receiving chamber 16a serves to receive the cut or trimmed edges of the mesh fabric 14, which is pressed into the receiving chamber 16a for clamping and fixing the mesh fabric 14 by means of an elongated clamping strip (not shown in detail). The clamping strip is preferably a keder-like, elastic rubber element.

[0044] At the in Fig. A hinge 18 is provided in the area of ​​each corner joint on the right frame member. The hinges 18 are each attached to the right longitudinal profile 4.

[0045] As in the Fig. As can be seen in Figure 2, the external receiving chamber 16b, which faces the outside of the frame in the assembled state of frame system 2, serves to receive a sealing element 20 in the form of a sealing brush. Alternatively, the sealing element can be designed, for example, as a sealing lip.

[0046] The connecting element 10 is, as in Fig. 2 and Fig. As can be seen in Figure 3, the connecting element 10 is essentially T-shaped, with the vertical leg of the T acting as a fixing shaft 22, which, in the assembled state, is inserted into a joining chamber 24 of the transverse profile 6. The joining chamber 24 is located approximately midway between the receiving chambers 16a and 16b. The horizontal leg of the T of the connecting element 10 is designed as a cover collar 26, which, in the assembled state, projects beyond the inner receiving chamber 16a of the longitudinal profile 4 in the corner area. The cover collar 26 has two screw-in openings 28, through which screw elements inserted into these openings are screwed to a T-nut 30 in the longitudinal profile 4. This screw connection enables a reliable, stable, and torsion-free connection between the longitudinal profile 4 and the transverse profile 6.

[0047] In the section defined by the middle cross-section 6 and the section in Fig. A door handle 32 is arranged in the left longitudinal profile 4 of the frame corner area. The construction of the door handle 32 is described below. Fig. 2, Fig. 3, Fig. 4, Fig. 5 and Fig. 6 explained in more detail.

[0048] The door handle 32 is approximately triangular in shape and comprises a triangular, rigid handle frame 34 and a handle plate 36 that can pivot relative to it. The handle frame 34 has an adjacent side A and an opposite side G, with the adjacent side A oriented along the transverse profile 6 and the opposite side G oriented along the longitudinal profile 4.

[0049] Preferably, the triangular handle frame 34 is approximately right-angled; in particular, the angle between the adjacent side A and the opposite side G is preferably 90°. The angle between the hypotenuse side H and the adjacent side A, as well as the angle between the hypotenuse side H and the opposite side G, are equal and approximately 45°. This allows the handle frame 34 to be easily positioned in the corner area between the longitudinal profile 4 and the transverse profile 6.

[0050] The handle frame 34 is in particular a triangular metal part on which protruding screw plates 38 are formed on the adjacent and opposite sides A, G ( Fig. 4) The mounting plates 38 each have two recesses for screw elements 40, with which the handle frame 34 is rigidly screwed to two T-nuts 42 in the assembled state.

[0051] The T-nuts 42 ( Fig. 3) In the assembled state, the T-nuts 42 are positively and, preferably, force-fitted into the receiving chambers 16a, the T-nuts 42 expediently having an outer contour adapted to the inner profile contour of the receiving chamber 16a. The T-nuts 42 have two threaded bores which, in the installed state, are accessible for screwing them to the mounting plates 38 via a longitudinal profile slot in the receiving chamber 16a. The recesses of the mounting plate 38 and the threaded bores of the T-nuts 42 are suitably arranged complementarily to each other so that they can be easily screwed together.

[0052] The mounting plates 38 extend - as in Fig. 4 evident - essentially over the entire length of the adjacent and opposite sides A, G with a rectangular recess 44 in the Fig. 4. Lower left corner area. In recess 44 - as in Fig. Figure 3 clearly shows that the cover collar 26 of the connecting element 10 is arranged in a space-saving manner when installed. The screw plates 38 on one side and the recess 44 on the other result in a particularly shallow installation depth for the door handle 32 while maintaining high stability.

[0053] The handle frame 34 has a centrally located, approximately trapezoidal recess 46 in which, when assembled, the similarly trapezoidal handle plate 36 is arranged. When closed, the handle plate 36 lies in the plane of the handle frame 34. Fig. Figure 5 shows that the handle frame 34 further comprises a frame structure 48 and a lower cover plate 50. The frame structure 48 includes the screw plates 38, as well as a retaining contour 52 facing the recess 44. In the assembled state, the lower cover plate 50 is screwed to the frame structure 48 from below and extends essentially over the entire length of the hypotenuse side H.

[0054] To facilitate the opening of the frame system 2 by a user, the handle plate 36 is pivotably arranged relative to the handle frame 34. In particular, the handle plate 36 is positioned in the drawing plane in Fig. The handle 32 can be pivoted inwards, allowing the user to reach behind the handle frame 32 to open the frame system 2. Conversely, the door handle 32 is also designed so that the handle plate 36 can be pivoted outwards from the plane of the drawing, allowing the handle plate 36 to be used as an additional lever for pivoting the frame system 2 if required.

[0055] For this purpose, the trapezoidal handle plate 36 has an integrally formed, cylindrical support element 54 at its base, which, in the assembled state, rests on an approximately wedge-shaped support surface 56 of the cover plate 50. The handle plate 36, the support element 54, and the support surface 56 interact like a hinge joint.

[0056] The lower end of the support surface 56 is positioned slightly lower than the upper surface of the cover plate 50, thereby creating an approximately trough-like indentation which, in the assembled state, prevents the support element 54 from slipping out towards the recess 46.

[0057] In the assembled state, the cover plate 50 is screwed to the frame structure 48, thereby ensuring that the support element 54 is held securely in a form-fitting manner between the frame structure 48 and the support surface 56 of the cover plate 50, and that the handle plate 36 can be pivoted easily relative to the handle frame 34 due to the wedge-shaped design of the support surface 56 on the one hand and the cylindrical shape of the support element 54 on the other.

[0058] The handle plate 36 has a retaining contour 58 on the side facing away from the support element 54, which, in the assembled state, is located directly opposite the retaining contour 52 of the frame structure 48. In the assembled state, a magnetic element 60 is arranged facing each other in the retaining contours 52 and 58.

[0059] The T-nut-like magnetic elements 60 are essentially rectangular and have oppositely directed magnetic polarity. The magnetic elements 60 are positively and force-fitted in the retaining contours 52, 58, the magnetic elements 60 advantageously having outer contours adapted to the inner profile contour of the retaining contours 52 and 58, respectively. For axial fixation within the retaining contours 52, 58, the magnetic elements can be screwed into the respective contours ( Fig. 7).

[0060] As in Fig.As can be seen in Figure 8, a wedge-shaped stop surface 62 is arranged below the support surface 56. Compared to the support surface 56, the stop surface 62 has a steeper slope and is slightly shorter with respect to the hypotenuse side H than the support surface 56. In the installed state, the stop surface 62 prevents the handle plate 36 from pivoting too far. Preferably, the pivot radius of the handle plate 36, determined by the stop surface 62, is selected such that, even at the maximum pivoted position of the handle plate 36, the magnetic elements 60 attract each other just strongly enough to close the door handle 32 automatically.

[0061] For fastening the mesh 14 on the door handle side, the mesh 14 is clamped between the frame structure 48 and the cover plate 50 in the assembled state. For improved hold, the lower cover plate 50 of the handle frame 34 has a clamping structure 64 with a number of rib-like projections and recesses. The rib-like clamping structure 64 is arranged along the hypotenuse side H and thus additionally secures the support element 56 against slipping out towards the inside of the frame.

[0062] Preferably, the frame system 2 is designed according to a modular principle. This means that, for example, the longitudinal and transverse profiles 4, 6, as well as the tread cross profile 12 and the mesh fabric 14, are manufactured in various standard sizes, and a consumer can assemble an individual frame system 2 for different door openings.
