The ends (27) of the vertical rod sections (14) are each received in rotationally fixed manner in a holder (16). The horizontal rod sections (15) interlock with a frame-side stop (20) and a door-side catch (22).

Description

The invention relates to an insect screen door with a wing pivotally received in a frame or a door frame, and a closing device for automatically closing the wing.

Such an insect screen with the features according to the preamble of claim 1, for example, is made DE 100 39 829 B4 known. As a closing mechanism there is a torsion bar is used, which is rotatably disposed with one end in a provided on a mounting or a frame holding means, while the other end is also rotatably received in a arranged on the wing holder. Now, if the door is pivoted relative to the frame, the torsion bar is twisted, so that builds up a restoring force.

At the DE 100 39 829 B4 known additional door is a usual, rising only to one side door. Occasionally, however, swing doors are installed, which can be pivoted to both sides starting from a closed position in which the swing door rests in the door frame or the door frame. This is with the out DE 100 39 829 B4 Known door not possible, also can not be realized on the described therein closing mechanism which is formed over only one, parallel to a vertical side of the sash torsion bar.

The invention is based on the problem of specifying an insect screen, which can be closed automatically with pendulum swivel bearing via a locking mechanism.

To solve this problem is provided according to the invention in an insect screen door of the type mentioned that according to claim 1, the closing means of the pendulum wing received two mutually parallel to substantially 90 ° angled torsion bars in the corner region between the frame or the door frame and the Wings extend, the rod ends of the substantially vertically extending rod sections each in a holder are rotatably received, while between the substantially horizontally extending rod sections engages a frame or door floor side arranged stop and a wing side arranged driver.

In the insect screen comes a locking mechanism comprising two separate, preferably biased in the mounting position torsion bars, which are each angled at substantially 90 °, used, wherein a torsion bar for the return of the one-way door and the other for the return the door opened in the other direction. The torsion bars are rotatably held with the end located at the vertical rod portion in a holder which is arranged on the frame or on the door frame, so are rotated relative to this fixed point. The other end cooperates with a driver-stop combination, which are provided in the region of the vertical wing and frame or door frame sections. A stop is provided on the frame or the door frame, while a catch is provided on the hinged door. Both are positioned so that they engage between the two substantially horizontally extending rod sections, which rod sections extend for several, for example 5 - 10 cm in the horizontal. In the rest position, the two bar sections are located both on the driver and on the stop, which are provided relatively close to each other, to. If the door is swiveled to one side, a rod section is taken over the driver and thus twisted a torsion bar, while the other at the stop, which remains stable. This torsion bar is not twisted. The built-up restoring force of the twisted torsion bar extends in conjunction with acting on the wing lever, formed on the horizontal bar section and the relatively far from the pivot point of attack on the wing, from the pivoted door readily returned to the closed position.

Correspondingly reversed is the operation in a swing in the other direction. Now the previously stationary torsion bar is pivoted or twisted following the driver of the pivoting movement of the wing, while the previously twisted rod remains at rest on the stop.

Overall, results in a very simple and safe-working locking system that ensures the provision of the swing door in each case.

As described, the holder z. B. on the frame or on the door floor. The holder can either be in a frame-side groove (the mounting frame as well as the casement usually consist of four mitred cut, held together by pressing angle profile sections preferably aluminum) recorded where it is vertically displaceable and can be fixed in the desired position. Alternatively, it would also be conceivable to arrange for direct storage of the door on the door frame, there a corresponding mounting rail, where the holder can be vertically displaced and fixed by a suitable screw (grub screw), so that the corresponding height position can be adjusted.

It should be noted at this point that, of course, the holder also on the casement itself, there also preferably in a corresponding groove, where it is vertically displaceable and can be fixed, is possible. In this embodiment of the invention, therefore, the closing device comprising the two torsion bars and the holder would remain fixed on the wing and with this on and removed, while in a fixation of the holder on the frame / door the locking device would remain there in an expansion of the door. In an arrangement of the bracket on the wing, the operating principle inevitably rotates after the lower, located in the bracket end is taken with the wing. In this case, the restoring force is generated via the torsion bar abutting the stop when swinging the door, which, after the holder, where it is fixed against rotation, is pivoted with the wing, is twisted and generates the restoring force.

In order to ensure a safe pivoting movement and storage, the wing is preferably pivotally mounted via hinges, wherein a hinge arranged in the region of the vertical bar sections and one of the hingedly connected hinge parts of these in one or in each case an opening is interspersed. The hinges should be positioned as close as possible to the respective corner areas of the wing or the sash to ensure a safe pivoting movement. After there, the torsion bars are arranged there, according to the invention, a particularly executed hinge part is used, which has one or two corresponding openings through which the torsion bars run, which are automatically guided through these openings. Again, it is useful if the interspersed by the rod sections hinge part in the frame-side groove or the groove of the door floor side arranged or mounting rail when positioning the bracket on the frame or on the door frame, or positioning the bracket and thus the locking device on the wing in the wing-side groove is vertically displaceable and fixable, which applies mutatis mutandis to the other hinge part, which is correspondingly vertically displaceable and fixable on the opposite part. This embodiment also allows a simple adjustment of the height of the hinge by moving the individual parts in the correspondingly assigned groove while guiding the torsion bars.

It is also expedient if a rod guide positioned in the region of the substantially 90 ° bend of the torsion bars is provided, which ensures that the bars are securely guided in this area, which is important for good torsion directly following the pivot angle. This rod guide can also serve as a stop or contact surface for the torsion bars at the same time. Conveniently, this rod guide is in a groove of one of the components to which the holder or the hinge part are slidably and fixably accommodated arranged, so therefore also vertically displaceable and fixable in order to be able to be positioned accordingly.

Furthermore, expediently, a cover sleeve, which is penetrated by the substantially vertically extending bar cuts, be provided to encapsulate and protect them.

In any case, to ensure that in case of a longer installation time, possibly slightly forgiving frame or wing, the door still in the Closed position is brought, it is expedient if two or more closer to each other in approaching magnetic closure elements are provided on the opposite side of the closing device vertical side of the wing and the frame or the door. These closing elements, for example, two magnets that tighten when approaching, support the provision by the closing device, so the torsion bars, so that even if due to structural conditions, etc., the closing device does not apply enough force to the increased power demand due to the delay The door is securely closed. In a corresponding manner and with corresponding effect, alternatively or additionally, at least one of the substantially horizontally extending wing side and frame side or door leaf side can be provided with two or more closing elements that can be magnetically brought into contact with each other, preferably both in the region of the upper and the lower horizontal side. Incidentally, a certain fixation of the insect screen door in the closed position is achieved on all these closing elements, so that too easy opening can be avoided for example by wind draft or the like.

The stop and the driver are formed in a particularly simple manner by means of frame or door floor side or wing side arranged screws, which are screwed as a simple sheet metal screws in the existing usually made of aluminum corresponding profile section. Although already a closing device comprising the two parallel, separately operating torsion bars in the upper or in the lower corner region is sufficient, appropriate closing devices may expediently be provided in both corner regions, whereby of course the restoring force is correspondingly increased.

For further sealing of the insect screen in the closed position against possibly penetrating insects are expediently in the frame-side groove or groove of the door floor side arranged or to be arranged mounting rail and / or on the circumferential, external grooves of the wing forming profile bars one or more sealing elements, in particular brushes or Rubber seals or sealing tapes, are used, which lie in the closed position on the opposite part of the frame or door frame, etc.

Fig. 1 shows a schematic diagram of an insect screen door 1 according to the invention comprising a wing 2, which is verschenkbar in both directions, so oscillating, is accommodated in a mounting frame 3, which in turn is arranged on a door frame 4. The wing 2 has a sash 5, which consists of four metal profile bars, which are interconnected. As part of an insect screen 6, for example, a fine-meshed metal or plastic grid, added. Accordingly, the mounting frame 3 consists of several individual metal profile bars, which are pressed into a frame. The basic structure of such an insect screen is known per se.

Fig. 2 shows in the form of a schematic representation of - based on Fig. 1 - Area of the upper left corner. Shown is a section of the sash 5 and the mounting frame 3. Both consist of corresponding profile sections, which, as shown in dashed lines, are fixed by means of compressed connection angle 7. The pivotal mounting of the wing 2 on the frame 3 via a plurality of hinges 8, of which in Fig. 2 only two are shown. The hinges 8 are designed with their two hinge parts 9, 10 so that a double-sided pivoting is possible. The fixation takes place via a corresponding axle pin 11, which is in a simple manner by the two hinge parts 9, 10, forming the axis of rotation, inserted. In a correspondingly simple manner, it can also be dismantled so that the wing 2 can be removed from the mounting frame 3.

Also provided is a locking device 12, which will be discussed in greater detail below. The locking device 12 comprises two torsion bars 13, of which in the side view in Fig. 2 only one can be seen Fig. 9 shows a top view of both torsion bars 13 which are parallel to each other. Both torsion bars 13 have a vertical bar section 14 and a horizontal bar section 15. They are essentially in the area between the Sash frame 5 and the mounting frame 3. On the mounting frame 3, a holder 16 is provided, in which the two lower ends of the bar sections 14 of both torsion bars 13 are rotatably received, which can be effected via a corresponding geometry of the plug receptacle and the bar ends. The holder 16 is in a corresponding groove on the mounting frame 3, in which the holder is vertically displaceable and fixable, which can be done by means of a screwed into a threaded receptacle 17 grub screw, added.

The locking device further comprises a rod guide 18, which is also vertically displaceable in the groove of the mounting frame 3 and fixed via a corresponding screw via a threaded bore 19. This rod guide has, as will be discussed below, one or more corresponding openings through which the torsion bars 13 run. The torsion bars 13 are executed angled, they describe an angle of substantially 90 °. Provided is also provided on the mounting frame 3 stop 20, formed by a screwed screw 21, and provided on the wing driver 22, also formed by a simple screw screw 23. The function of these elements will be discussed below.

The following are the various sectional views according to the FIGS. 3 to 8 described in more detail.

Fig. 3 shows a section along the line III - III in Fig. 2 , Shown is the mounting frame 3 and the sash 5. Both have a corresponding groove 24, 25, in each of which a hinge part 9, 10 as described height adjustable, so slidably received. For fixing here are corresponding threaded holes 39, 40 (see Fig. 2 ), in which appropriate screws can be used for fixing. Shown is also the bolt 11, which forms the axis of rotation.

Fig. 4 shows a sectional view in the region of line IV - IV in Fig. 2 , The section extends through the holder 16, which is also received in the mounting frame side groove 24 as described vertically displaceable and fixable. The holder has two receptacles 26 which serve to receive the ends 27 of the two torsion bars 13. Obviously, the receptacles 26 are square, the same applies to the bar ends 27, so that they are taken rotationally fixed in the receptacles 26. As Fig. 4 also shows, in the groove 25 of the sash 5, a sealing element 28, here a brush seal, added, inserted here, be to seal the gap between the sash 5 and the mounting frame 3 in this area. For clarity, the bar ends 27 are not shown here.

Fig. 5 shows a sectional view taken along the line V - V in Fig. 2 , This view passes through a cover sleeve 29, which is also visible in the groove 24 on the mounting frame 3 and also has two here, however, circular, therefore not rotatably overlapping apertures 30 which are penetrated by the two torsion bars 13 and the bar sections 14 what a corresponding rod guide is achieved.

Fig. 6 further shows a section along the line VI - VI in Fig. 2 passing through the hinge 8. It can be seen on the hinge part 9, which is accommodated on the mounting frame 3 in the local groove 24, two apertures 31 are provided which are penetrated by the rod portions 14, that is, the hinge part 9 is designed specifically with respect to the locking device 12 according to the invention.

Fig. 7 shows a sectional view taken along the line VII - VII Fig. 2 by the rod guide 18, which is also received vertically displaceable and fixable in the mounting frame side groove 24. The rod guide has two circular openings 32 which are penetrated by the vertical bar sections 14 of both torsion bars 13. Immediately after the rod guide, the - see Fig. 2 - Has an upper stop 33, with which it abuts the vertically running profile bar of the mounting frame 3, and engages acting as a rotation stop between the two torsion bars 13, bend the two torsion bars 13 and go into the respective horizontal bar section 15. This also runs in the gap between the two frames 3 and 5 and cooperate with the stopper 20 and the driver 22. These two are each in separate representations in Fig. 8 which is a view along the line VIII - VIII in Fig. 2 shows shown.

Shown is in Fig. 8 on the right of the mounted on the mounting frame 3 stop 20, formed on the screw 21. The stopper 20 extends to just before the sash 5 so that it can vorbeischwenken below the stop. In a similar way, see Fig. 8 left, provided on the casement 5 of the driver 22 in the form of a screw 23. It also extends to just before the mounting frame 3, so that the pivoting movement is possible.

The function of the stopper 20 and the driver 22 results from the FIGS. 9-11. FIG. 9 shows the wing 2 in the closed position. In this engage the driver 22 and the stopper 20 between the two horizontal bar sections 15 of both torsion bars, the sections 15 are thus applied to both. Will now starting from the closed position according to Fig. 9 the wing 2 - based on the above-mentioned supervision - pivoted to the right ( Fig. 10 ), so takes the driver 20, which is pivoted with the wing 2, the in Fig. 9 10 and 10, while the left rod section 15 of the other torsion bar remains resting against the stop 20. As a result of the deflection of the rod portion 15 via the driver 22 of the torsion bar 13, which is rotatably received with its lower end 27 in the holder 16, twisted. This torsion generates a restoring force. The restoring force acts continuously on the driver 22 and on this on the wing 2 and urges this back in the Fig. 9 shown closed position. Here, only the torsion bar 13 shown in the figures on the right is active.

Otherwise, or vice versa, the function in a pivoting of the wing, starting from Fig. 9 to the left, as in Fig. 11 shown. In this case, the driver 22 takes the in Fig. 11 On the left shown rod portion 15 of the torsion bar, while the right rod portion in this case on the stop 20, which is arranged fixed on the mounting frame 3 rests. Here now the left torsion bar 13 is twisted, the rod end 27 is also rotatably received in the holder 16. In a corresponding manner, a restoring force is also here exerted that the torsion bar 13 exerts on the driver 22 on the wing 2 and this pushes back into the closed position.

As a result of the holder of the torsion bars in the holder 16 and the guide in the rod guide 19 in the range of Torsionsstababwinkelung safe guidance and thus a safe and equal swinging action achieved torsion of the respective Torsionsstabs is possible, and therefore also the corresponding structure of a sufficiently high Restoring force for returning the wing 2.

The two torsion bars are expediently prestressed in every possible embodiment of the insect screen door, that is to say they exert a restoring force on the driver 22 or the stop 20 already in the closed position. For this, e.g. in an arrangement of the locking device 12 on the mounting frame 3, the rod ends 27 and the receptacles 26 on the holder 16 carried out such that when inserting the rod ends 27 in the receptacles 26, the rod sections 15 are not parallel to the mounting frame 3, but at an angle, preferably approx 90 °, possibly also less, projecting from it, crossing each other towards the other frame side. For assembly, the rod sections 15 are then rotated back before the onset of the wing 2 under construction of the restoring bias and snapped over the stop 20. Inevitably, they then each exert a biasing force on the stopper 20 and after the onset of the wing 2 also on the driver 22, so that when entering the swung back wing 2 in the closed position, the torsional restoring force does not drop to zero, but still the default Preload is given, but after the restoring rod portion 15 runs with running into the closed position against the stop 20, the wing 2 can not move further, this is braked over the current to the stop torsion bar.

Fig. 2 also shows two closing elements 34, 35, one of which is arranged on the mounting frame 3 and the other on the casement 5, in each case in the region of one of the horizontally extending profile bars. These closing elements act magnetically together, preferably both are permanent magnets, wherein both magnets are arranged so that they attract each other when approaching. This magnetic interaction or attraction supports the closing movement of the wing, which is generated via the locking device 12 and serves to fix the wing 2 in the closed position. Of course, distributed over the horizontal length can be provided a plurality of such magnetic closure elements, as these can of course also be provided in the region of the lower horizontal profile sections.

In a similar way, see Fig. 12 , On the vertical portions of the sash 5 and the mounting frame 3 corresponding closing elements 36, 37 may be provided, which are also arranged here - as well as in the closing elements 34, 35 - in corresponding recesses in the respective profile bar. These are also preferably corresponding magnets, via which the closing movement is supported, after the two closing elements 36, 37 attract and thus pull the door into the closed position, even if, for whatever reason, this alone on the effect the locking device should not happen. Of course, several such closing element pairs can be arranged over the vertical length.

Obviously, the profile of the profiled bar of the sash frame 5 provided in this area corresponds to that of the profiled bar used on the opposite side as well as on the horizontal sides, thus likewise having the groove 24, in which here as well as on the opposite side (and correspondingly on the horizontal sides, not shown), a corresponding sealing element 38, here also a sealing brush, is used.

It should be noted at this point that the use of a mounting frame 3 is not mandatory. Of course, it would also be conceivable to store the casement 5 directly to the door frame. In this case, the corresponding hinge part as well as the Torsionsstabhalterung and the rod guide on the door frame or arranged there mounting rail, which should also preferably have a groove for vertical adjustment of the corresponding parts, arranged. In a similar way would be - based on Fig. 12 - Then arranged on the door frame, a corresponding mounting rail or, for example, a magnetic tape to cooperate as a corresponding magnetic closure member with the arranged on the casement magnetic closure member.

Finally, it should be noted that the invention is not limited to the arrangement of the closing device or the torsion bars on the mounting frame or in case of elimination of the mounting frame on the door frame or a corresponding mounting rail, etc. Rather, it would also be possible to arrange the holder, the rod guide and the torsion bars, etc. positionally fixed to the sash, the function or the interaction with the driver and the stop would then be essentially the same, but it is twisted each of the torsion bar, the abuts against the stop, after this point of attack due to the arrangement of the bracket on the sash twisted the corresponding rod end and therefore the rod is twisted, while the entrained over the driver Torsionsstab is not twisted after his rod end rotated as a result of Mitverschwenkung the holder together with the driver becomes.
