EP2320022B1 - Hinge for an insect and/or pollen protection screen - Google Patents

Description

The invention relates to a hinge for the pivotable connection of an insect and / or pollen protection grid with a frame, in particular with a frame edge of a building exterior door frame, according to the preamble of claim 1. Such a shearing is z. B. from the EP 1 898 041 A1 known.

To protect housing openings, such as window or door openings (balcony or patio doors), serve as a frame mountable insect, particle or pollen guards, which are inserted into a profile frame, which in turn should cover the building opening as fully as possible. Here, the most flexible adaptation to different opening sizes is desirable.

Furthermore, it is desirable both a possible unproblematic frame assembly as well as a simple insertion of the protective mesh or fabric in the profile frame. In addition, a disassembly should be possible, in particular to replace individual parts. Furthermore, a secure mounting of the covered with the protective mesh fabric (mesh or cloth) profile frame should be guaranteed at the destination, especially on a door. In addition, the overall system should be as flexible as possible in order to adapt to different on-site found boundary conditions for assembly.

A protective grid for attachment to a window frame, for example, from DE 20 2007 009 166 U1 known. The known protective grid comprises a composite of profile rails, can be placed in front of the window frame grid frame with vertical and horizontal bars, which are connected to each other via corner joints. The rails are designed as hollow chamber profiles. One to the window frame open receiving channel serves to receive a welt, to which the grid (mesh) is attached. The grid covers the Frame opening of the lattice frame and thus the window opening against ingress of foreign particles permeable to air.

In a frame system for covering a window or door opening often one-piece and rectangular corner connectors are used for connecting longitudinal and transverse profiles. Also, the longitudinal and transverse profiles of frame systems, such as door or window openings, be bolted together. In order to movably connect the framed insect or pollen guard to a frame edge of a building door frame, hinges are provided with an axle and two bushings, as well as perforated door hinges for fastening the hinges by means of screws or nails. However, a nondestructive mounting of the insect or pollen grille is not possible by means of such fasteners, since they leave corresponding holes in the building frame, which is extremely undesirable.

The invention is therefore based on the object while avoiding the disadvantages mentioned to provide a suitable hinge for pivotally mounting an insect or pollen grille on a building frame.

This object is achieved by the features of claim 1. Advantageous embodiments, developments and variants are the subject of the dependent thereupon dependent claims.

For this purpose, the hinge has a protective grid side fixable, hereinafter referred to as a profile band first band part and a rahmenseitg fixable, hereinafter referred to as a frame band second band part, which is articulated, ie pivotally connected to the first band part. On the frame band, a clamping leg is held in an adjustable clamping distance for frame-side clamping fixation of the frame band and thus the hinge and on this the insect or pollen guards on a frame edge of the building frame. The hinge thus enables a non-destructive and at any time detachable and reliable connection of the insect or pollen guard with, for example, a door frame edge as a clamping hinge.

The insect or pollen door frame system can be mounted to a door frame using two or three hinges without damaging it through holes or screw holes. For this purpose, each hinge is designed to produce a clamp with the door frame. For this purpose, the first, safety-belt-side band part (profile band) of the hinge is fixed to the protective grid profile frame by means of screwing.

For screwing is advantageously a sliding block, which in the assembled state in a corresponding, accessible via a profile longitudinal slot for mounting screws receiving chamber of the hollow profile designed as an open front hollow profile, in particular longitudinal profile, inserted and at the desired position along the frame or longitudinal profile with the profile band of screwed respective clamping hinge. Into the sliding block introduced internally threaded holes are accessible via the profile longitudinal slot of this receiving chamber and are brought in the assembly of the hinge with provided in its profile band corresponding openings in coverage. A screwing of the hinge with the longitudinal profile is thus possible in a simple manner.

On the frame band of the clamping hinge, the clamping leg is held with adjustable clamping distance on the side of the leg facing away from the hinge joint. For this purpose, the clamping leg is suitably screwed to the frame band of the clamping hinge, so that the clamping distance is adjustable by a corresponding number of screw revolutions. Appropriately, the clamping leg for this purpose has a preferably provided with an internal thread screw channel which receives a clamping screw. The frame band then has a screw opening, over which the threaded shaft of the clamping screw is guided into the screw channel of the clamping leg and screwed there to the internal thread.

The clamping leg is suitably guided, for which purpose the tower belt of the clamping hinge expediently protruding from the belt plane

Tabs are formed with guide grooves. In these guide grooves integrally formed on the clamping leg and perpendicular to this guide lip is guided.

In an advantageous development, the tabs of the frame band of the clamping hinge for adapting to the frame corner to each other at least approximately at right angles arranged for mounting the hinge in a formed by the corner joint of the longitudinal profile with the cross-section frame corner, while the guide lip of the clamping leg is bent at right angles. A recess in the frame band forms a band gusset, which is bounded by the tabs of the frame band and the bent guide lip of the clamping leg at two mutually approximately rectangular sides. The gusset formed by the corner joint of the longitudinal profile and the transverse profile is therefore not covered by this in the assembled state of the clamping hinge. The hinge or its clamping leg does not protrude into the frame interior in the corner area, i. in the plane of the hollow sections (longitudinal and transverse profiles) frame plane. At the bent guide lip of the clamping leg, a clamping plate is formed, which has two mutually perpendicular and parallel to each one of the guide tabs of the second hinge part plate edges. These are at the Eckmontage the clamping hinge in the frame corner of the frame at the corner edges.

In order to keep the distance between the door frame and the (profile) frame system caused by the clamping hinge as low as possible, the hinge is pot-shaped. For this purpose, a recess is made in the frame band, in which the profile band of the hinge rests when the insect screen is closed. The mounting distance between the insect screen, so the profile frame system and the door frame is thus ultimately determined by the small thickness of the frame hinge of the hinge.

For a suitable self-closing of the mounted insect screen door, ie the mounted frame system on the door frame carries a hinge pin (hinge rod) of the hinge joint a spring element, in particular a coil spring, for generating a force acting on the profile band and on this on the frame system restoring force. A spring end of the spring element is suitably introduced into a receiving opening of a T-shaped corner connector, which connects two longitudinal profiles with a transverse profile within the frame system. With this opening in the corner connector a corresponding opening in a decorative cap is aligned, so that the spring end is inserted via the decorative cap in the corner connector.

The advantages achieved by the invention are in particular that due to the formation of the hinge as a clamping hinge a pivotable and thereby nondestructive clamp connection of an insect or pollen protection grid can be made to a frame edge of a building door frame. The development as a corner hinge also allows optimal positioning of the clamping hinge in a frame corner of the profile or grid frame system. In this case, the corner hinge on the side facing away from the mounting side frame outside of the profile or grid system in the corner joint is almost completely covered by the there mutually perpendicular frame profiles and therefore almost invisible. In addition, the or each clamping hinge can be mounted in a simple manner both on the frame system of the insect or pollen guard and on the building door frame.

A profile frame system with two or three such clamping hinges including sliding blocks and screws is preferably provided as a modular system with a number of longitudinal and transverse profiles, wherein at least the longitudinal profiles on profile longitudinal slots accessible receiving chambers for the sliding blocks have, with which the hinge is screwed.

The Fig. 1 to 4 show in various perspective views and in an exploded view ( Fig. 2 ) formed as a hinge hinge 1 with a hereinafter referred to as a profile band first band part 2 and a subsequently referred to as a frame band second band part 3. The two band parts 2 and 3 are connected by means of a hinge pin 4 with each other. For this purpose, the frame band 3 on two spaced-apart sockets 5, which receive a socket 6 of the profile strip 2 between them. In the assembled state of the hinge 1, the bushings 5 and 6 are aligned with each other and are interspersed by the hinge pin 4, which forms the hinge axis of the hinge joint of the hinge 1, so that the hinge pin 4, the two bands 2 and 3 of the hinge 1 interconnects. Between the two sockets 5 extends into the frame band 3 in a recess 7, the dimension of which are adapted to that of the profile strip 2 such that this completely rests in the recess 7 and is thus absorbed by the frame band 3 in the manner of a cup hinge or pot band, without stand out from the xy plane of the frame band 3.

The profiled strip 2 has two screw holes 8 designed as countersunk holes for fastening screws 9 with a metric thread running in the exemplary embodiment as a hexagon socket. The mounting screws 9 are screwed for mounting the hinge 1 in corresponding internal thread openings 10 of a sliding block 11, as described below with reference to FIG Fig. 5 is explained in more detail.

On the second band part or frame band 3, a clamping leg 12 is held displaceably in an adjustable clamping distance a _k perpendicular to the band plane xy of the frame band 3 in the z direction. For this purpose, two guide plates 13 are integrally formed with guide grooves 14 on the frame band 3. The tabs 13 protrude in the z direction out of the xy plane of the frame band 3. In the guide grooves 14 of the tabs 13 integrally formed on the clamping legs 12 guide lips 15 are guided. Between the guide lips 15, a guide or screw channel 16 is formed, which has at its the frame band 3 facing the channel end a cylindrical inner threaded collar 17. In this, the provided with a metric external thread screw shank of an adjusting and clamping screw 19 is screwed, which is screwed via a screw hole 20 in the frame band 3 in the screw channel 16.

In the in the Fig. 1 to 6 illustrated embodiment of the formed for a clamp attachment and as a corner hinge hinge 1 which are integrally formed on the frame band 3 tabs 13 to each other approximately at right angles. Accordingly, the guide lips 15 of the clamping leg 12 are bent approximately at right angles. The guide plates 13 of the frame band 3 and the bent guide lip 15 of the clamping leg 12 thus limit two sides a band gusset 18 within which the frame band 3 is recessed, ie free of material. In the clamping connection of the hinge 1, the frame band 3 of the hinge 1 is located at a in the Figures 1 and 2 dashed line indicated door frame 21 or the like or on the frame edge, while the clamping leg the door frame 21 in the corner, ie within a door frame corner 22 engages behind. For this purpose, a clamping plate 23 which is integrally formed with the formation of the clamping leg 12 to the guide lip 15, substantially square approximately to form two mutually perpendicular plate edges 24. For corner mounting in the frame corner 22 of the door frame 21, these plate edges 24 of the clamping leg 12 abut against corner edges 25 of the door frame 21, which are usually formed by an inner frame rebate ( Fig. 2 ).

The Fig. 5 and 6 show the formed as a corner hinge clamping hinge 1 in the assembled state of a partially illustrated frame system 26 of an insect repellent or pollen protection grid. The frame system 26 comprises longitudinal and transverse profiles, of which a longitudinal profile 27 and a transverse profile 28 are shown in sections and are mounted perpendicular to one another in a corner region. For this purpose, a screw connection by means of fixing screws 29 is provided in the exemplary embodiment, which are screwed transversely to the longitudinal profile 27 extending through this into the transverse section 28 on the front side.

In the region of this corner connection of the profiles 27, 28, the profiled strip 2 of the hinge 1 is screwed by means of the screws 9 to the longitudinal profile 27. For this purpose, the in Fig. 5 invisible sliding block 11 is inserted into a receiving chamber 30 of the longitudinal profile 27 from one of their end faces. The threaded openings 10 of the sliding block 11 are accessible via a profile longitudinal slot 31, which opens into the receiving chamber 30. To attach the hinge 1 on the longitudinal profile 27, the screw openings 8 of the profile strip 2 are brought into coincidence with the internal thread openings 10 of the sliding block 11 and then the fastening screws 9 are screwed into the threaded openings 10 of the sliding block 11. In this way, the hinge 1 with the frame system 26 is fixed, but releasably connected.

The clamping leg 12 protrudes with its clamping plate 23 on the in Fig. 5 visible frame inside in the door frame 21 or the like, not shown here. In the assembled state, the clamping plate 23 of the clamping leg 12 engages behind the corresponding frame rebate of the door frame 21 in the frame corner 22. By means of the clamping screw 19, the clamping connection between the hinge 1 - before or after this is connected to the frame system 26 - and the door frame 21. For this purpose, the clamping leg 12 is tensioned by means of the clamping screw 19 in the direction of the frame band 3. This clamp connection is non-destructive and can be detached at any time.

In the longitudinal profile 27 and in the transverse profile 28 a further, the frame interior facing receiving chamber 32 is provided in each case, which in turn are accessible via a profile longitudinal slot 33. During assembly of the frame system 26 and for covering the frame inner surface (inner frame plane) 34, the cut edges of a net or mesh fabric 35 (FIG. Fig. 6 ) and clamped by means (not shown) Kederelemente or the like by being pressed over the profile longitudinal slots 23 in the inner receiving chambers 32.

Fig. 6 shows in detail the frame profile 26 with in the frame corner (corner joint) 22 between the longitudinal profile 27 and the cross section 28 mounted hinge 1 in a plan view of the frame system 26. It can be seen that due to the recessed band gusset 18 in the frame hinge 3 of the hinge 1 this only insignificantly in the limited by the longitudinal and transverse profiles 27 and 28 frame surface 34 projects, which is covered with the here indicated by dashed lines guard 35.

The Fig. 7 to 10 show an embodiment of the turn designed as a hinge hinge 1 for a longitudinal side mounting on the frame system 26 in the region between an upper and a lower frame corner 22. The profile band or first band part 2 is movably connected to the frame band or second band part 3 again by means of the hinge pin 4 , In the composite State of the hinge 1, the sockets 5 and 6 are aligned with each other and are penetrated by the hinge axis of the hinge 1 forming hinge pin 4. The profiled strip 2 is completely in the recess 7, without protruding from the xy plane of the frame band 3. The fastening screws 9 are in turn screwed into the corresponding internal threaded openings 10 of a further sliding block 11 for mounting the hinge 1. The clamping leg 12 is held in the adjustable clamping distance a _k perpendicular to the belt plane xy of the frame belt 3 in the z-direction slidably on the frame belt 3.

For this purpose, two guide plates 13 are integrally formed with guide grooves 14 on the frame band 3. The tabs 13 protrude in the z direction out of the xy plane of the frame band 3. In the guide grooves 14 of the tabs 13 integrally formed on the clamping legs 12 guide lips 15 are guided. Between the guide lips 15, a guide or screw channel 16 is formed, which has at its the frame band 3 facing the channel end a cylindrical inner threaded collar 17. In this, the provided with a metric external thread screw shank of an adjusting and clamping screw 19 is screwed, which is screwed via a screw hole 20 in the frame band 3 in the screw channel 16.

In contrast to the embodiment as a corner hinge formed on the frame band 3 and out of the band plane xy in the z direction protruding tabs 13 are aligned with each other and provided as possible at the outer end or at the outer edge of the frame band 3. The tabs 13 in turn form mutually facing guide grooves 14 in which the guide lip 15 of the clamping leg 12 for adjusting the adjustable clamping distance a _{k is} guided displaceably. The clamping plate 23 of the clamping leg 12 is bent at its leg end 36 approximately S-shaped and thus forms there compared to the clamping plate 23 after the FIGS. 1 to 6 narrow clamping web 37 for a reliable clamping fixation on the corresponding frame edge of the door frame 21 or the like.

The assembly of the hinge 1 in turn, preferably the longitudinal profile 27 is analogous to the assembly of the executed as a corner hinge hinge 1 according to the Fig. 1 to 6 , For this purpose, in turn, the hinge 1 is fastened with its profiled strip 2 by means of the sliding block 11 and the fastening screws 9 on the longitudinal profile 27 ( Fig. 10 ). In Fig. 9 comparatively clearly visible is the screw channel 16 with the local internal thread 17 for the clamping screw 19 in the clamping leg 12 and there between the guide lips 15th

In order to automatically return this and thus the frame system 26 in the closed position when mounted insect or pollen guards, the hinge pin 4 of the hinge 1 carries a spring element 38 in the form of a spiral spring. This generates a spring restoring force, the hinge 1 and its bands 2 and 3 and thus the frame system 26 in the in the Figures 5 . 6 and 10 shown closed position leads and holds there sufficiently stable. For this purpose, the hinge pin 4 is extended beyond the axial hinge length out, wherein in the assembled state, the coil spring 38 is seated on an extended shaft portion 39 of the hinge pin 4.

One of the spring ends 40a of the spring element 38 is bent at right angles and lies in the assembled state on the door frame 21 - and there on a frame rebate - frame inside. The other spring end 40b is inserted in a manner not shown in a T-shaped corner connector 41, for which purpose there is provided a corresponding receiving opening. The T-shaped corner connector 41 connects two longitudinal profiles 27 and a transverse profile 28, for example in the region of the frame center of the frame system 26 with each other. About a corresponding recess 42 in the T-shaped corner connector 41 of the nut 11 in the receiving chamber 30 of the in Fig. 10 lower longitudinal profile 27 are inserted for screw fixation of the hinge 1.
