Abstract
Description
The invention relates to a frame system for an insect screen door, comprising a number of profile strips (longitudinal and transverse profiles) mounted or mountable perpendicular to one another in frame corner areas, and a handle element. It further relates to an insect screen door with such a frame system and a handle element for it. To protect building openings, such as doorways (balcony or patio doors), insect, particle, or pollen screens are mounted as frame systems. These screens are inserted into a frame system, which in turn covers the building opening as completely as possible. Ideally, the system should be flexible enough to adapt to different opening sizes, easy to install, and allow for simple attachment or insertion of the (protective) mesh or netting onto the frame system or into the profile frame. Disassembly should also be possible, particularly for replacing individual parts. Furthermore, the frame, covered with the (protective) netting or netting, should be securely fastened at its intended location, especially on a door.Furthermore, the overall system should be as flexible as possible to allow adaptation to different local conditions encountered during assembly. 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, assembled from profile rails and positioned in front of the door frame, with strip-like vertical and horizontal profiles (profile strips) connected to each other via profile or corner connectors. The profile strips or rails are designed as hollow chamber profiles. A receiving channel, open towards the door frame or building opening, serves to receive a flexible clamping or keder strip for attaching the grille or mesh to the frame system. The grille or mesh covers the frame opening of the frame system or profile frame, and thus the door opening, in a permeable manner to prevent the ingress of foreign objects or particles. In the frame system or profile frame designed and installed for an insect screen door, a further transverse profile is typically arranged as a cross brace at approximately half the height of the longitudinal or vertical profiles. This transverse profile is also connected to the longitudinal or vertical profiles at the end-face corners via corner connectors, particularly T-shaped ones. A door handle is attached to one of the corner connectors via a tongue-and-groove connection for easier opening and closing of the insect screen door. Such a door handle offers only limited user comfort and low stability. From DE 10 2011 051 303 A1, a swing-gate handle is known as a door handle for 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. The swing-gate part is held in the clear opening against the spring force of a spring mounted on the swing-gate part and the frame part, or via a grooved insert in an edge groove of the opening, in order to allow the swing-gate part to swing open against the spring force and to allow access through the clear opening. The door handle is roughly rectangular and can be inserted into an approximately U-shaped retaining contour in the door leaf, so that the frame section is held on three sides. This design is particularly disadvantageous in a modular frame system of the type mentioned above. Because a special retaining contour is required in the area of a crossbar for the door handle, the flexibility of the frame system is adversely reduced. From DE 10 2014 000 286 A1, a frame system for an insect and / or pollen screen door is known, comprising longitudinal and transverse profiles mounted perpendicular to each other in frame corner areas, a connecting element for attaching a single transverse profile in a corner area along one of the longitudinal profiles, and a handle section spanning the corner area, which is screwed to T-nuts located in receiving chambers of the transverse and longitudinal profiles. The handle section has a rigid handle frame screwed to the T-nuts and a handle element pivotally coupled to it, which rests in a polygonal recess of the handle frame. The invention is based on the objective of providing a particularly suitable frame system and, in particular, a handle element for it. Specifically, the frame system should be easy to install, expediently as comfortable to operate or handle as possible, and preferably as airtight as possible. Furthermore, an insect screen door with such a frame system and a handle element for such an insect screen door are to be provided. With regard to the frame system, the problem is solved according to the invention with the features of claim 1, with regard to the insect screen door with the features of claim 14, and with regard to the handle element with the features of claim 15. Advantageous embodiments and further developments are the subject of the dependent claims. The frame system is specifically designed and configured for an insect and / or pollen screen door. The frame system comprises a number of longitudinal and transverse profiles mounted or mountable perpendicular to each other in (frame) corner areas, with a vertically oriented frame system including an upper and a middle, and preferably also a lower, transverse profile. The frame system features a handle element located in a corner area between the central transverse profile and an adjacent longitudinal profile. The longitudinal and transverse profiles each have at least one receiving chamber, extending lengthwise and accessible via a longitudinal slot, for attaching a mesh fabric. The handle element has a triangular frame with a handle opening and two handle parts. The frame has two mutually perpendicular or right-angled frame struts, which allow the handle element to be mounted in the corner area within the receiving chambers of the longitudinal profile and the central transverse profile. The handle element suitably has a base strut connecting the mutually perpendicular frame struts. This base strut advantageously incorporates a receiving chamber, preferably U-shaped in cross-section, for a clamping strip (keder strip) for attaching and / or securing the mesh fabric to the handle element. The handle element preferably comprises a handle plate as the first handle part and a handle bracket as the second handle part, wherein the handle bracket or the handle plate is pivotably or pivotably mounted in the handle frame. The mounting is preferably designed or configured as a hinge or pivot joint, or acts as such. In an advantageous embodiment, the handle element is fastened in the receiving chamber of the longitudinal profile and in the receiving chamber of the central transverse profile by means of clamping strips, in particular elastic or flexible ones. Suitablely, the respective clamping strip is fastened to the corresponding frame strut of the handle element by means of at least one screw, preferably with two spaced-apart screws. Advantageously, the clamping strip has parallel clamping legs which are clamped within the corresponding receiving chamber. The clamping strip, and thus the handle element, can be advantageously clamped to the frame system by means of the respective screw, similar to an expansion anchor, due to the expansion of the clamping legs or the clamping strip itself. In a particularly advantageous design, the handle and the grip plate of the handle element are rotatably held or mounted on a joint pin, preferably a common one. The joint pin suitably runs between the mutually perpendicular frame struts of the handle frame. Additionally or alternatively, the joint pin is inserted or can be inserted into joint or bearing openings in the handle frame, which are provided in the mutually perpendicular frame struts and accessible from their outside. Advantageously, the handle opening of the handle frame is polygonal, preferably hexagonal, and suitably has two pairs of sides, each with two parallel opening sides or edges. Additionally or alternatively, the handle plate, as the first handle part of the handle element, is polygonal, particularly hexagonal, with two pairs of sides, each with two parallel plate edges or contours. A fold is expediently formed on each of the frame struts of the handle frame, projecting into the handle opening and reducing its cross-sectional area. The handle arm of the handle element, in its closed position, suitably rests against these folds. The handle plate is particularly advantageously adapted to the handle opening of the handle frame and pivotally mounted within the handle frame so that, when the handle is operated, the handle plate can swing through the handle opening. To ensure the tightest possible, and especially particle-tight, seal of the handle opening, the handle bracket covers any gap remaining between the handle plate and the folds of the handle frame by resting against these folds. A sealing brush is advantageously provided for particle-tight sealing or covering of the handle opening. According to an advantageous embodiment, the handle element is provided with magnetic or magnetizable elements, in particular to position the handle parts in a defined closed position while covering the handle opening, or to ensure a secure and / or as (particle-)tight closure of the handle opening of the handle frame. For this purpose, at least one magnetic element and / or at least one magnetizable element, or a metal element, preferably strip-shaped or plate-like, is suitably provided on the handle element and / or on the handle frame. Advantageously, the magnetic element is inserted or can be inserted into a receiving groove. The respective receiving groove is provided on one of the mutually perpendicular frame struts of the handle frame or, preferably, on their respective fold. Preferably, the respective or a further magnetic element is inserted into a corresponding receiving groove in the handle plate. Suitablely, the metal element(s) (metal plate) is attached to the handle bracket of the handle element, in particular by a material bond. An embodiment of the invention is explained in more detail below with reference to a drawing. Figure 1 shows a front view of a frame system consisting of profile strips (longitudinal and transverse profiles) arranged transversely (horizontally) and longitudinally (vertically) and connected in the corner areas by means of corner connectors, with a mesh fabric clamped inside as insect and / or pollen protection, forming an insect screen door with a handle element, in particular a double-flap swing handle, as the door handle. Figure 2 shows an enlarged detail II from Figure 1 in a rear view of the handle element in its connection with the frame system in the corner area of a central transverse profile and an adjacent longitudinal profile. Figure 3 shows the handle element in a front view with a substantially triangular handle frame and with two handle parts pivotally connected to it, showing a view of a handle bracket.4 the handle element in a rear view showing a handle plate as the (first) handle part and clamping strips on mutually perpendicular frame struts of the handle frame, Fig. 5 in a representation according to Fig. 3 the handle element with the handle bracket removed and showing magnetic elements, Fig. 6 in a perspective view the handle bracket as the (second) handle part with metal strips (metal plates) attached to bracket tabs, Fig. 7 the handle element in an exploded view showing magnetic elements seated in receiving grooves of the handle frame, Fig. 8 in a perspective view the handle frame showing a bearing point with a pivot pin inserted for the handle parts and into a receiving chamber on a base strut, Fig. 9 the handle parts in a perspective view showing magnetic elements seated in receiving grooves of the handle plate, and Fig.10 in an exploded view the handle parts with a pivot pin seated in a bearing sleeve of the handle plate. Corresponding parts and sizes are marked with the same reference symbols in all figures. Fig. 1 shows a front view of a frame system 2 mounted to an insect or pollen screen door 1, consisting of (vertically oriented) longitudinal profiles 3 and (horizontally oriented) transverse profiles 4, which are mounted perpendicular to each other in the (frame) corner areas. For this purpose, an upper transverse profile 4, adapted to the desired dimensions of a building door opening, is stably connected to a longitudinal profile 3 in the left and right upper frame corners of Fig. 1 by means of a corner connector 5. A building door opening is understood to be, in particular, a balcony, patio, or front door. With reference also to Fig. 2, in the central area of the frame system 2, a central transverse profile 4 is connected to the opposing longitudinal profiles 3 via connecting elements 6. The longitudinal profiles 3 are connected to a lower transverse profile 4 at the underside of the frame system 2 in stable corner connections using corner connectors 7. In the exemplary embodiment, a tread profile 4a is provided on the underside of the frame. The lower transverse profile 4 can also be designed as such. The longitudinal profiles 3 and the upper, middle, and / or lower transverse profile 4 are essentially identical aluminum strips with a hollow profile (not shown in detail). On the rear surface of the frame system 2 in its assembled state, a mesh fabric 8 is mounted on the longitudinal and transverse profiles 3, 4 to provide insect protection, pollen protection, or, more generally, particle protection. The mesh fabric 8 is attached by means of keder-like, preferably flexible, clamping strips. These can be pressed into receiving chambers 9 during assembly. These chambers are accessible via longitudinal slots 10 running along the profile or frame's rear surface in the longitudinal direction L. Each receiving chamber 9 serves to receive the cut edges of the mesh fabric 8. These edges can be pressed into the receiving chamber 9 to clamp and fix the mesh fabric 8 in place by means of an elongated clamping strip (not shown). The clamping strip is suitablely a keder-like, elastic rubber element. In the exemplary embodiment, three hinges 11 are provided on the right-hand side of the frame system 2 in Fig. 1, spaced apart from each other in the longitudinal direction L of the longitudinal profiles 3. The hinges 11 are attached to the longitudinal profile 3 there. By means of the hinges 11, the frame system 2 or the insect screen door 1 can be pivotally attached or hinged to a wall reveal or to a door frame. The respective longitudinal profile 3 can have a receiving chamber, facing the outside of the frame or the outside of the frame system 2 in its assembled state, for receiving a sealing element, for example, a sealing brush. A handle element 12 is attached to the frame system 2. This handle element is positioned in a corner area between the central transverse profile 4 and the adjacent longitudinal profile 3. The handle element 12 has a triangular handle frame 13 with a handle opening 14 and a first handle part in the form of a handle plate 15, as well as a second handle part in the form of a handle bar 16. The handle element 12 is attached to the longitudinal profile 3 and the transverse profile 4 in the corresponding corner area of the frame system 2 by means of screws 17. With reference also to Figures 3, 4 to 5, a U-shaped receiving chamber 18 is provided on the handle frame 13 for a clamping strip (not shown) for attaching the mesh fabric 8 or a (fabric) cut edge to the handle frame 13 of the handle element 12. The handle frame 13 has two mutually perpendicular or right-angled frame struts 13a and a base strut 13b connecting them. The receiving chamber 18 is provided on or along the base strut 13b. The handle element 12 is mounted, or can be mounted, in the corner area of the frame struts 13a within the receiving chambers 9 of the longitudinal profile 3 and the central transverse profile 4. For this purpose, a clamping strip 19 is attached to each frame strut 13a by means of two screws 17. Each clamping strip 19 has parallel clamping legs 19a, which, in the assembled state, engage in the corresponding receiving chamber 9. The clamping legs 19a of the clamping strips 19 are widened by the screws 17, thus ensuring a reliable clamping fixation of the respective clamping strip 19, and consequently of the handle element 12, to the frame system 2. The handle parts 14, 15 are attached to the handle frame 13 by means of a common pivot pin 20 in a bearing or bearing point 21 in the manner of a hinge or pivot joint. The pivot pin 20 runs between the mutually perpendicular frame struts 13a of the handle frame 13. The pivot pin 20 is inserted or can be inserted into pivot or bearing openings 22 of the frame struts 13a of the handle frame 13. The pivot or bearing openings 22 provided in the mutually perpendicular frame struts 13a are accessible from the outside of the handle frame 13. The handle parts 15, 16 are mounted in the handle opening 14 of the handle frame 13 of the handle element 12 and are pivotably movable, either individually or together. With reference also to Figures 7 and 8, the handle opening 14 of the handle frame 13 is hexagonal and has two pairs of sides, each with two opposing and parallel opening sides or edges 14a, 14b. Similarly, the handle plate 15, as the first handle part of the handle element 12, is hexagonal with two pairs of sides, each with two opposing and parallel plate edges or contours 15a, 15b. The area of the handle plate 15 is preferably only slightly smaller than the clear dimension or the opening area of the handle frame 13. As can be seen in Figures 5 and 8, a fold 23 is formed on each of the frame struts 13a and preferably also on the base strut 13b of the handle frame 13. These folds project into the handle opening 14 and reduce its clear dimension accordingly. The handle plate 15 is adapted to the handle opening 14 and, in particular, to the clear dimension between the folds 23, such that the handle plate 15, which is pivotally mounted in the handle frame 13 of the handle element 12, can swing through the handle opening 14 when it is actuated. In the closed position, the handle bracket 16 of the handle element 12 rests against the folds 23 of the handle frame 13. The handle bracket 16 covers a gap 24 of the handle opening 14 remaining between the handle plate 15 and the folds 23 of the handle frame 13 (Figure 5). With reference also to Figures 6 and 7, as well as 9 and 10, the handle 16 has two handle tabs 16a and a handle or grip strut 16b connecting them. A sealing brush 25 is provided on this strut for particle-tight sealing or covering of the handle opening 14 of the handle frame 13 or the handle element 12. For this purpose, the handle or grip strut 16b of the handle 16 has a receiving chamber or groove 9a (Figure 10). Bearing sleeves 26 for the passage and reception of the pivot pin 20 are provided on the free ends of the bracket tabs 16a. A bearing sleeve 27 of the handle plate 15, arranged between them, is aligned with the bearing sleeves 26. The sleeve-like bearing sleeve 27 is integrally formed with the plate edge 15a of the handle plate 15 associated with the bearing point 21. In the assembled state of the handle element 12, the pivot pin 20 passes through the bracket-side bearing sleeves 26 and the plate-side bearing sleeve 27, which is aligned with them. As can also be seen in Fig. 5, the handle element 12 has magnetic or magnetizable elements in the form of magnets 28 and metal plates or strips 29. This positions the handle parts 15, 16 in a defined closed position, flush with the handle frame, covering the handle opening 14 and ensuring a secure and, as far as possible, (particle-)tight closure of the handle opening 14 of the handle frame 13. For this purpose, a receiving pocket or groove 30 is provided on each of the two frame struts 13a or on the folds 23 of the handle frame 13, into which the magnets 28, which in this embodiment have a double-T shape in cross-section, are inserted. Similarly, the handle plate 15 has a receiving groove 31 on each of its plate edges 15b for a corresponding magnet 28. Metal strips or plates 29 are attached, in particular by adhesive bonding, to the tabs 16a of the handle 16. The size and arrangement or positioning of the metal strips or plates 29 are such that they cover the adjacent magnets 28 of the handle frame 13 on the one hand and the handle plate 25 on the other. In the closed position, the handle 16 thus holds the handle plate 15 in an adhesive bond. This bond, which can be released via the adhesive magnetic elements 28, 29, is held detachably on the handle frame 13 by means of the handle 16. The positions of the magnetic elements 28 and the metal strips 29 can also be reversed, in which case the magnets 28 are located on the handle 16 and the metal strips 29 are located on the handle frame 13 or on the handle plate. In summary, the invention relates to a frame system 2 for an insect and / or pollen screen door 1, comprising a number of longitudinal profiles 3 and transverse profiles 4, and a handle element 12 arranged in a corner region between one of the longitudinal profiles 3 and a central transverse profile 4, wherein the handle element 12 has a triangular handle frame 13 with a handle opening 14, a handle plate 15, and a handle bracket 16, and wherein the handle plate 15 and / or the handle bracket 16 are pivotably or pivotably mounted in the handle frame 13. The handle element 12, or its handle frame 13 and handle parts 15 and 16, are preferably die-cast parts, particularly preferably made of die-cast zinc. The invention is not limited to the embodiments described above. Rather, other variants of the invention can also be derived by a person skilled in the art without departing from the subject matter of the invention. In particular, all individual features described in connection with the various embodiments can also be combined with one another in other ways without departing from the subject matter of the invention.
