Description

The invention relates to an insect protection device for a door opening, for mounting in a building opening, with a winding shaft rotatably mounted in a roller housing and a developable from this and extendable from the roller shutter housing grid or fabric web according to the preamble of claim 1 for insect-tight overstretching the building opening. Such a protective device is for example from the US 5,868,191 known.

In particular, for the installation of insect protection systems in building openings, primarily on or in front of doors (patio doors, balcony doors or floor-to-ceiling sliding windows), at least two different principles of such protection devices are typical, namely hinged hinges on the door frame or on the wall reveal the building opening hinged doors, such as a from the DE 20 2010 012 403 U1 Known frame system for insect or pollen guards.

On the other hand, horizontally mountable insect screen roller blinds are often used, in particular in front of a window, whose protective fabric is horizontally removable from a take-up roll or winding shaft, which is rotatably mounted in a housing. Such an insect screen is, for example, from DE 103 51 336 A1 known. However, such insect protection roller blinds are only partially suitable for the possible insect-tight overstretching of a door opening, especially since a relatively long vertical path would have to be passed when pulling out the protective fabric.

From the DE 60 2006 000 307 T2 is also known as insect protection mountable protective device, the protective fabric of a take-up reel, which is rotatably mounted in a housing, is vertically removable.

From the above US 5,868,191 is known as a light or insect protection on a window or on a building opening protective device known which is telescopically adjustable to adapt to the size of the window or the building opening. A fabric web provided for this purpose, which can be unwound from a take-up roll rotatably mounted in a housing, has a middle inflexible fabric section and, for this purpose, a flexible fabric section on both sides. The fabric web is guided with its parallel to the extension direction (upper and lower) fabric edges in each of three-part, telescopically slidable guide rails of a three-sided closed telescopic frame. Also, the take-up reel and this receiving housing, on which the guide rails are held with the open frame side of the telescopic frame forming rail ends, in their length telesokartig adjustable and this also carried out in three parts. In particular, in the provision of kits of such protective devices to be assembled at the destination for (self-) assembly in front of a building door in a corresponding building opening (wall reveal) of individual components, it is desirable both in terms of packaging and in particular with regard to transport the individual components of the protective device easily manageable and easily transportable dimensions, in particular component lengths have. These desirable requirements for such a protection device, in particular as insect protection (insect protection device), are so far not satisfactorily fulfilled when using the roller blind principle.

The invention has for its object to provide an insect repellent device that is as easy as possible to handle packaging, transport and installation.

This object is achieved by a protective device with the features of claim 1. Advantageous embodiments and further developments are the subject of the dependent claims.

For this purpose, trained for vertical mounting insect protection device has a split winding shaft in a likewise divided roller blind housing and a developable and extendable from the roller blind housing via a housing slot grid or fabric web (insect screen) for insect-tight overstretching a building door or building window opening. Conveniently, the mesh or web is in one piece and, preferably for packaging and / or transport purposes, preferably folded to half the total length in a pre-assembled condition and then rolled or rolled up and rolled up by folding into two parallel web roll sections, preferably each of half track roll footage laid.

The roller blind housing is formed from a first housing part or housing section with a housing section length which corresponds at most to half the overall length of the roller housing and from a second housing part or housing section assembled with the first housing part and assembled in the assembled state with a housing section length corresponding to the total length of the roller housing. The section length of the two housing parts (housing sections) is preferably the same and corresponds in each case to half the total length.

Analogously, the winding shaft is expediently formed from a first shaft or hollow pipe section as well as from a second shaft or hollow pipe section which can be mounted end-to-end with the first shaft section and is non-rotatably joined in the assembled state by means of a joining element. One of the shaft sections has a maximum of half the total length of the winding shaft, while the other shaft section then has the corresponding to the total length of the winding shaft section length. The section lengths of the two shaft sections are preferably in turn equal and each corresponding to half the total length of the winding shaft.

The protective device also has a lateral edge side fastened to the grid or fabric web, preferably designed as a hollow profile Auszugsleiste, which is also divided and assembled in the assembled state to its overall length. The division corresponds to this analogous to the winding shaft and the blind housing turn vorzugswiese half the total length of the Auszugsleiste. As a result, the smallest possible packaging size and component length of the individual components (winding shaft, roller blind housing and Auszugsleiste) is achieved. In addition, the kit of the protection device can also be handled accordingly easy during transport. The Auszugsleiste is preferably designed as a hollow profile or hollow profile strip.

The attachment of the grid or fabric web on the composite of the shaft sections winding shaft on the one hand and on the hollow profile-like Auszugsleiste on the other hand is suitably carried out in the manner of a clamp mounting a corresponding side edge of the grid or fabric web, preferably by means of additionally provided Kederleisten. Also, the corresponding side edges of the mesh or fabric web can be designed with corresponding, kederartigen Wulstabschnitten, which may be formed in or from seams or glued grid or fabric eyelets. In this flexible or rubber-elastic rods or piping can be inserted.

For this purpose, in turn, the Auszugsleiste formed from a first and second profile section preferably with half the total length extending in the profile longitudinal direction, provided with a longitudinal slot receiving chamber for the side edge and optionally provided, kederartiges fastener on. Analogously, the winding shaft or its respective shaft section suitably also has a longitudinal groove for receiving a preferably kederartigen retaining element for the side edge attachment, in particular clamp attachment, the grid or fabric web.

The profile sections of the hollow profile or Auszugsleiste be suitably joined in the course of assembly frontally by means of a joining element. For this purpose, the profile sections expediently have a joining chamber extending in the longitudinal direction of the profile for receiving a respective joining element of the profile-side joining element. In the assembled state, the joining element is seated with the respective joint in the joining chamber of the corresponding profile section to produce a preferably positive and non-positive or frictional plug connection. An approximately centrally provided web of the joining element is suitably used as a stop for the respective profile section or for the respective joint, so that it can be inserted only up to this stop web in the corresponding joining chamber of the profile section.

In an advantageous embodiment, the shaft sections of the winding shaft are formed with an over the section length extending longitudinal groove for receiving a side edge and / or preferably kederartigen retaining element for the side edge side clamping or plug-fastening of the grid or fabric web. In this case, the longitudinal groove is pulled like a sickle from the lateral surface of the respective shaft portion in the pipe interior. In this way is suitably formed in the cross-section approximately U-shaped and, with the exception of a longitudinally extending exit slot for the grid or fabric web, closed receiving chamber for the holding element and the side edge of the grid or fabric web.

The joining element provided for connecting the two shaft sections for producing the overall length of the winding shaft is preferably also a hollow tube, that is essentially designed as a hollow tube. A longitudinal groove extending over the shaft section length, which engages over the longitudinal groove of the respective shaft section on the tube side, is preferably likewise drawn in like a sickle, that is to say in practice introduced as a material recess into the hollow tube jacket of the joining element.

The joining element also has, preferably in the center, a contact element, in particular a locking pin, as a joining stop for the hollow tube sections of the winding shaft. This ensures that in the course of the joining operation, the joining element is preferably inserted over half their total length in the respective shaft portion, and thus for the other shaft portion of the winding shaft is an approximately equal length section of the joining element for the joint connection of the shaft sections to the winding shaft available.

When using a separate plug pin as a contact element of this suitably via corresponding aligned openings or holes of the joining element is suitably radially, but preferably eccentrically - ie edge-like - inserted into the joining element at a position at which the retracted longitudinal groove of the respective shaft portion of the winding shaft whose groove bottom is spatially positioned inside the respective shaft section. As a result, on the one hand, a reliable stop for the respective shaft portion is formed. On the other hand, the longitudinal groove for receiving the retaining element at the corresponding stop point is not closed, so for the retaining element for fixing the side edge of the grid or fabric web at this point not blocked.

While in the joined state of the shaft portions of the winding shaft by means of the preferably hollow tube-like joining element already due to the suitably bead-like depressions, which in the joining state einliegen those of the waves of the shaft sections in that of the joining element already provides a torsion-proof plug connection, the relative rotational movement of the shaft sections of the winding shaft prevented against each other, at least one further form and / or frictional connection between the joining element and the two shaft sections is provided in an advantageous development. For this purpose, the shaft sections of the winding shaft on the tube side preferably have spring-like joining contours, which correspond with outside, opposite joining contours in the joining element. Here, suitably a number or plurality of such joining contours on the inner circumference of the shaft sections on the one hand and on the outer circumference of the joining element preferably arranged evenly distributed. As a result, in the course of the joining connection, there is practically a spline between the joining element and the two shaft sections, so that overall a particularly reliable joint connection is produced between the two shaft sections.

Suitably, in the assembled state of the protective device with its vertical orientation within the building opening horizontally - that is, almost sideways - pulled out grid or fabric web in suitably opposite, horizontally extending guide rails edge. For this purpose, the corresponding horizontally extending side edges of the grid or fabric web sit in these guide rails at least slightly.

Alternatively or preferably in addition to these horizontal guide rails, the protection device also comprises a guide rail which is vertical in the installed state and which is mounted on the wall or reveal side of the building opening opposite the roller blind housing. In this vertical guide rail sits suitably - in particular at about half the height of the protective device in the assembled state - a locking element. This locking element corresponds to a latching or joining contour in a grip element, which is connected via a preferably plug-mounted joint connection with one of the profile sections of the Auszugsleiste or attached thereto. In the extended state of the grid or fabric web with suitably complete coverage of the building opening the mesh or fabric web in this state via the latching connection between the handle member and provided in the vertical guide rail latching element securely, but releasably held.

Both for optical and designerischen as well as in particular for connection reasons, the front side in the course of assembly against each other guided housing sections in the region of the local shock or housing section edges are suitably embraced by means of a sleeve-like connecting element. At this connection element eyebolts can be formed to the blind housing with the rotatably mounted therein winding shaft and then rolled up grid or fabric web reliable in the building opening and there to fasten on a corresponding opening or Leibungswand by means of screws.

The connecting element expediently does not completely surround the opening edges of the housing sections of the roller shutter housing, but rather releases the housing slot for the grid or fabric track. On the connecting element plug-in pins are preferably formed, which engage in the assembled state in corresponding insertion openings of the housing sections, so that a secure and aligned connection of the housing sections is made.

Corresponding parts are provided in all figures with the same reference numerals.

The FIGS. 1 and 2 show a protective device 1 as insect protection for vertical mounting in a building opening, preferably in front of or on a door or Door opening, with a roller blind housing 2 and with a pull-out of this lattice or fabric web 3 and with an attached thereto Auszugsleiste. 4 Fig. 1 shows the protection device 1 with fully retracted grid or fabric web 3, while Fig. 2 the protective device 1 with approximately extended grid or fabric web 3 shows. The horizontally extendable at vertically mounted protection device 1 grid or fabric web 3 is hereinafter referred to as insect screens.

The protective system 1 further comprises two in the assembled state and in particular after successful vertical mounting two horizontally extending guide rails, namely an upper guide rail 5 and a lower guide rail 6 and a vertical guide rail 7. The guide rails 5, 6, 7 are with the blind housing 2 to a rectangular frame system mounted. The connection of the horizontal guide rails 5 and 6 to the roller shutter housing 2 via frontal end caps 8a and 8b as upper or lower completion of the roller shutter housing second

The roller shutter housing 2 and the Auszugsleiste 4 and the vertical guide rail 7 are divided, that is, each carried out in two parts and assembled in the illustrated vertical mounting state to the apparent total length or vertical total height of the protective device 1. For this purpose, the roller shutter housing 2 is composed of a first housing section 2a with a housing section length L ₁ corresponding to a maximum of half the total length of the roller housing ₂ and a second housing section 2b assembled with the first housing section 2a and assembled in the assembled state with a total length (L ₁₂ = L ₁ + L ₂ ) of the roller shutter housing 2 corresponding housing section length L ₂ formed. The housing section lengths (section length) L ₁ and L _{2 of} the roller shutter housing 2 suitably correspond in each case to half of the total length L ₁ + L _{2 of} the roller shutter housing 2.

Similarly, the preferably hollow profile-like pull-out strip 4 is composed of a first and second profile section 4a and 4b, whose respective profile section length (section length) L ₁ , L ₂ that of the housing sections 2a and 2b of the roller shutter housing 2 correspond. Also, the vertical guide rail 7 is formed of two rail sections 7a and 7b, whose respective rail section length (section length) L ₁ , L _{2 of} those of the housing section 2a, 2b of the roller shutter housing 2 and those of the profile section 4a, 4b, the Auszugsleiste 4 correspond.

At the Auszugsleiste 4 a handle element 9 is attached. This has latching elements (latching contours, latching hook) 10. At in Fig. 2 shown horizontally extended insect screen 3 locks the handle member 9 by means of its locking element 10 with a provided in the vertical guide rail 7 locking element (latch hook pair) 11. This is in Fig. 1 at transparently illustrated lower rail portion 7b of the guide rail 7 recognizable and in Fig. 2 shown separately in the manner of an exploded view. Fig. 13 shows this, designed as a latch hook pair latching element 11 within the guide rail 7 and there in the lower rail section 7b. Out Fig. 12 is the handle side, corresponding locking element 10 of the handle element 9 comparatively clearly visible.

Fig. 3 shows the area of the lower (left) corner of the protection device 1 with the cap 8b removed. This allows a view of the blind housing 2, in the lower housing portion 2b. Visible is the (lower) end face or the corresponding shaft end of a winding shaft 12, which is rotatably mounted within the blind housing 2, and on which the insect screen 3 is wound up. A central shaft opening 13 of the winding shaft 12 corresponds to a bearing pin 14, which is molded on the inner side of the cap 8b. In the assembled state, this bearing pin 14 is seated in the shaft opening 13 of the winding shaft 12 in a form-fitting manner and supports the winding shaft 12 at this end-face position in the roller housing 2.

Screw holes or holes 15 in a mounting bar 16 of Abdecckappe 8b serve to screw the protective device 1 in its vertical mounting in the Gebäuselaibung or -öffnung and there to a corresponding opening wall. One in a longitudinally slotted receiving chamber 17 of the Rollogehäuses 2 positively inserted, flexible or rubber-elastic sealing strip or sealing brush 18 serves to seal the blind housing 2 and thus the protection device 1 against the corresponding vertical wall of the building opening.

Fig. 4 shows the upper left corner of the vertically mounted protection device 1 overlooking the local cap 8a. Visible is an externally accessible threaded sleeve 19 with external thread and with a hexagon socket for receiving an Allen wrench. The threaded sleeve 19 engages in a manner not shown in the winding shaft 12 a form-fitting and allows rolling or winding the winding shaft 12 against the force of a return spring to adjust the spring force. When removing the insect screen 3 from the in Fig. 1 shown completely rolled up on the winding shaft 12 position in the in Fig. 2 shown extended (unwound) position, the mechanical return spring is tensioned, so that the insect screen 3 is automatically wound or rolled up on the winding shaft 12, if on the Auszugsleiste 4 no tensile force acts on the insect screen 3.

Fig. 5 shows the insect screen - so the grid or fabric web 3 - in a packaging, transport or pre-assembly state. In this example, the insect screen (fabric web) 3 is initially rolled up and laid in the rolled up state by folding in two parallel roller track sections 3a, 3b, each with half the web roll length. According to an advantageous alternative, the mesh or fabric web 3 is first folded to preferably half the total length (0.5 × L ₁₂ , with L ₁₂ = L ₁ + L ₂ ) and then rolled up, preferably from the fabric fold. In both cases, the fabric web 3 is in one piece and is ready for packing and transport ticks in half the total length.

The side edges (lattice edges) 20, 21 of the insect screen 3 are already designed as piping or Kederleisten or designed such that with a separately provided Kederleiste 22 as a holding element ( Fig. 8 ), the corresponding side edge 20, 21 can be fixed to the winding shaft 12. The other side edge 21 or 20 is then fastened analogously to the pull-out strip 4. In the assembled state is the insect screen 3 with its (horizontal) side edges 23 in the upper and lower guide rail 5, 6 out.

The (upper) cap 8a also has a mounting bar 16 with screw holes 15 for screw mounting the roller shutter housing 2 and thus the protection device 1 in the vertical mounting position on the facing (horizontal) opening wall of the housing opening.

Fig. 6 shows the essential components of the protective device 1 in disassembled state of the split roller housing 2, the split winding shaft 12 and the divided Auszugsleiste recognizable are the two profile sections 4a and 4b designed as a hollow profile strip Auszugsleiste 4th Similarly, the two are also designed as hollow sections housing sections 2a and 2b of the roller shutter housing 2 recognizable. Also, the two-part winding shaft 12, which is preferably also designed as a hollow profile, a first hollow tube-like shaft portion (hollow tube section) 12a and a second hollow tube-like shaft portion (hollow tube section) 12b. The section length L ₁ , L _{2 of} the two shaft sections 12a and 12b of the winding shaft 12 is again preferably the same or at least approximately equal and corresponds to half the total length of the winding shaft 12 in the assembled state.

Combined with Fig. 7 It can be seen that the respective shaft portion 12a, 12b of the winding shaft 12 has a groove-like retracted longitudinal groove 24. This longitudinal groove 24 is formed by an approximately U-shaped, tube-side groove wall 25 with an extending in the tube and wavelength direction V groove bottom 26. Visible, the longitudinal groove 24 is almost completely closed, with the exception of one in the longitudinal direction V of the respective shaft portion 12a, 12b extending longitudinal or exit slot 27 for the insect screen 3. In the longitudinal groove 24 is in the course of installation of the side edge or the side edge 20 of the insect screen 3 retracted and optionally by means of the likewise retracted into the longitudinal groove 24 Kederleiste 22 (FIG. Fig. 8 ) fixed in a clamp.

Inner wall side are formed on the sections 12a, 12b of the winding shaft 12 spring web-like joining contours 28 which extend as well as the exit slot 27 for the insect screen 3 in the tube longitudinal direction V, which corresponds to the vertical direction in the assembled state of the protective device 1. Preferably, a plurality of, in the exemplary embodiment, a total of seven such joining contours 28 are distributed uniformly on the inner circumference of the respective hollow pipe section 12a, 12b.

Combined with Fig. 8 is from the Fig. 7 a too in Fig. 6 shown joining element 29 for joining the two shaft sections 12a, 12b to the winding shaft 12 recognizable. The joining element 29 is in turn suitably hollow-tube-like and likewise formed with a longitudinal groove 30 which extends over the hollow tube section length V and extends in a bead-like manner. In the state inserted in the respective hollow pipe section 12a, the longitudinal groove 30 of the joining element 29 engages over the longitudinal groove 24 of the corresponding shaft section 12a, 12b on the inside. As a result, a rotationally fixed connection between the two shaft portions 12a and 12b is already made, so that they can not exert any relative rotational movement to each other.

In the pipe wall 31 of the joining element 29 corresponding groove-like joining contours 32 are introduced to the spring web-like joining contours 28 of the respective hollow pipe section 12a, 12b, z. B. retracted like a sickle. In plugged state of the joining element 29 in the respective shaft portion 12a, 12b is thus by a positive engagement of the joining contours 28 of the shaft portion 12a, 12b in the corresponding (opposite) joining contours 32 of the joining element 29 an additional joint connection and in particular a frictional plug connection between the joining element 29th and the respective shaft portion 12a, 12b. As a result, relative movements between the two shaft sections 12a, 12b of the winding shaft 12 are prevented in a particularly reliable manner and a secure seat of the friction element 29 is provided in the shaft sections 12a, 12b.

How out Fig. 8 can be seen, are in the hollow tube-like executed joining element 29 - seen in the longitudinal direction V preferably centrally - aligned openings 33 introduced. The position of these passage openings 33 is located virtually within the bead-like longitudinal groove 30. In the course of assembly, a plug or stop pin 34 is inserted into these aligned through holes 33. Its position, namely on the groove bottom 26 of the longitudinal groove 24 for the welt strip 22, is illustrated on one of the hollow pipe section 12a, 12b. Thus, it can be introduced virtually continuously in composite winding shaft 12 in the continuous longitudinal groove 24 of the hollow pipe sections 12a, 12b. In the course of the plug-in assembly of the joining element 29 in the respective shaft portion 12a, 12b of the winding shaft 12 of the inserted into the through holes 33 plug pin 34 serves as a stop, so that the joining element 29 can be inserted only with its half overall length in the respective shaft portion 12a, 12b.

Fig. 9 shows in conjunction with Fig. 6 the two housing sections 2a and 2b of the roller blind housing 2 in the pre-assembled state. As can be seen, the two hollow profile-like housing sections 2a, 2b have a housing or outlet slot 35 extending in the longitudinal direction V, over which the insect screen 3 exits the roller blind housing 2 and can be pulled out therefrom. In the assembled state, the two housing sections 2a and 2b abut each other with their opening edges 36 at the front.

For centering and fixing of the two housing sections 2a and 2b, a sleeve-like connecting element 37 is provided which surrounds the housing sections 2a, 2b in the region of their opening edges 36 with the exception of a slot 38 aligned with the housing slot 35. Fastening pins 39 are integrally formed on the connecting element 37 and, in the assembled state, fit into a form-fitting manner in corresponding joining openings 40 of the housing sections 2a, 2b. On the side opposite the slot 38, the sleeve-like connecting element 37 has two mounting or contact webs 41 with screw openings 42. This is an additional, approximately central Screw fastening of the roller blind housing 2 and thus allows the protection device 1 on the housing.

Fig. 10 shows the hollow profile-like Auszugsleiste 4 with their strip portions 4a, 4b in the pre-assembly. The profile sections 4a and 4b of the pull-out strip 4 each have a joining chamber 43 for receiving a respective joining sleeve 44a or 44b of a joining element 44 designed for plug-in mounting. Between the joining pieces 44a and 44b, a stop web 45 is formed, so that the joining element 44 can only be inserted with approximately half the length of the catch into the corresponding receiving chamber 43 of the corresponding profile section 4a, 4b of the pull-out strip 4.

An integrally formed in the region of the stop web 45 to the joining element 44 sleeve 46 forms an uninterrupted transition between corresponding receiving chambers 47 of the profile sections 4a, 4b. These are provided with a longitudinal slot 48, with which a sleeve slot 49 of the joining element 44 is aligned. The receiving chamber 48 of the Auszugsleiste 4 serves to receive the side edge or the side edge 21 of the insect screen 3, which for this purpose fed into the chamber 48 and possibly can be clamped by means of a likewise retracted into the chamber 48 Keder strip.

A further, the chamber 48 oppositely arranged receiving chamber 50 having a longitudinal slot 51 serves to receive a flexible or rubber-elastic sealing element or a sealing brush 52 which in the FIGS. 4 and 12 is relatively clear.

With view on 4 and 5 are the essential components of the protective device 1 recognizable, which is disassembled in the packaging and / or transport state in these components and assembled in the assembled state of these components. The sections 2a and 2b of the roller shutter housing 2 and the sections 4a and 4b of the pull-out strip 4 and the sections 12a and 12b of the winding shaft 12 and the sections 7a and 7b of the guide rail 7 to be mounted vertically can thus be arranged next to one another in the packaging, which is the packaging length on reduced about half the total length of the protective device 1. This ensures - compared to a one-piece protection device - also a much simplified transport of the protection device 1 in a vehicle, especially in a car.

Fig. 11 shows in conjunction with Fig. 10 one of the profile strips 4b of the Auszugsleiste 4 and the handle member 9 in a pre-assembly. The grip element 9 is constructed from two grip parts 9a and 9b. The handle part 9a has, in addition to two mutually spaced latching hooks 10, which cooperates with the insect rail 3 is provided with the provided in the vertical guide rail 7 locking element 11 for producing a releasable latching connection, a recessed grip 53 and a web-like plug-in part 54. The plug-in part 54 corresponds to a longitudinally slotted joining or plug-in chamber 55 of the profile section 4b.
