Description

The present invention relates to a protective arrangement for an opening which is surrounded by a border and which can be closed by means of a protective device comprising a frame. The invention also relates to a kit for such a protective arrangement and to a protective device for the protective arrangement.

In addition to the frame, the protective device preferably comprises a particularly textile fabric which is stretched across the frame. The textile fabric can be attached to the frame in a suitable and already known manner. The textile fabric can be designed as an insect protection fabric, sun protection fabric, privacy protection fabric, pollen protection fabric and/or similar fabric/knitted fabric. The protective device can therefore be an insect protection device, sun protection device, privacy protection and/or pollen protection device. The particularly rectangular frame of such a protective device often has four frame struts, with adjacent frame struts being arranged at a right angle to one another. The frame struts can each consist of at least one profile strip made of metal or plastic, with profile strips of adjacent frame struts being connected to one another via a corner connector. Alternatively, the frame can be bent from just one part (for example from a rod).

The border that delimits the opening can, for example, be a door frame to which, in addition to the protective device, a door leaf is pivotably attached. In this case, the opening is the door opening. The border that surrounds the opening can also be a window frame to which, in addition to the protective device, a window sash is pivotably attached. In this case, the opening is the window opening. The opening can also be a different type of opening in a building. The opening can also be formed in a vehicle or a caravan. The opening can, for example, be the door opening of a caravan, such as a mobile home or trailer.

If the protective device is designed as an insect screen door, it is known to attach the frame of the protective device to a door frame by means of hinges, so that the protective device can be pivoted between a closed position that closes the door opening and an open position that exposes the door opening. The hinges thus form a holding device with which the protective device is held to the frame. In order to hold the insect screen door in its closed position, it is also known to integrate a magnet in the frame on a side of the frame opposite the hinges, which interacts with a magnetizable element on the door frame in the closed position. Such an insect screen door is made, for example, from EN 10 2009 012 655 A1 To install the insect screen door, it is necessary to attach the frame of the insect screen door to the hinges the door frame, which requires the hinge to be manually attached to both the frame and the surround, which requires a certain amount of effort.

The object of the present invention is therefore to at least partially eliminate the disadvantages described with reference to the prior art and in particular to provide a protective arrangement and a kit for such a protective arrangement with which the effort for installing an (insect) protective arrangement can be reduced.

A solution to the problem is provided by the protective arrangement and the protective device with the features of the respective independent claim. Further solutions and advantageous developments of the protective arrangement, the kit and the protective device are specified in the above and following description and the subclaims, whereby individual features of the developments can be combined with one another in a technically reasonable manner. Embodiments and advantages described with reference to the protective arrangement are applicable to the kit and the protective device and vice versa.

The object is achieved in particular by a protective arrangement for an opening, which comprises a border surrounding the opening (i.e. limiting or edging it), a protective device comprising a frame for closing the opening and a holding device with which the protective device is held on the border. It is now proposed in particular that the holding device comprises at least one magnet, preferably at least two magnets, and that the frame of the protective device is magnetizable/magnetized in sections, so that the protective device is held/can be held on the border by means of the at least one magnet.

In other words: The basic idea of the invention is that the protective device is or can be attached to the frame surrounding the opening exclusively by means of at least one magnet and that the protective device is held on the frame solely by means of the at least one magnet. The magnet(s) and the protective device are thus arranged and designed in such a way that the protective device is held on the frame solely by the magnets. No further mechanical elements (such as hinges or suspension brackets) are therefore required to connect the protective device to the frame. The protective device is therefore held on the frame solely by the magnetic forces between the at least one magnet and the magnetizable/magnetized element of the frame. The at least one magnet can itself be attached to the frame simply by gluing or screwing. A particularly simple installation is possible if the frame itself is made of a magnetized or magnetizable material. In this case, the at least one magnet is simply attached to the frame due to the magnetic forces, whereby the position of the at least one magnet on the frame can be changed without great effort. By using at least one magnet, the installation of the protective arrangement on the enclosure is greatly simplified.

In a particularly preferred embodiment, it is provided that at least one (preferably exactly two or three and particularly preferably all) of the at least one magnet is arranged and/or designed as a hinge magnet such that the protective device can be pivoted about an axis predetermined by the at least one hinge magnet. In other words: the at least one, preferably the at least two, particularly preferably three, four or all magnets are arranged such that a (virtual) axis is predetermined around which the protective device can be pivoted between a closed position closing the opening and a position closing the opening. can be pivoted into the opening position, while the protective device continues to be held on the frame by means of the at least one hinge magnet. The (virtual) axis can be predetermined, for example, by the alignment of the magnetic field of one magnet or the magnetic fields of several magnets, wherein in the case of at least two magnets the magnets are arranged one behind the other on a straight line, wherein in particular a longitudinal extension direction of the at least one magnet is aligned parallel to the (virtual) straight line. Alternatively or additionally, the (virtual) axis can be predetermined by a surface design of the magnets and/or the frame.

The magnets therefore serve, on the one hand, to hold the protective device on the frame and, on the other hand, to specify a (virtual) axis around which the protective device can be pivoted. It is therefore no longer necessary to provide hinges with two straps each for a rotatable mounting of the protective device, one of which must be attached to the frame. The assembly of a protective device that can be opened by moving around the hinge axis is thus drastically simplified. Since the at least one magnet can have smaller dimensions than a strap on a hinge, the use of hinge magnets can be used to pivot a protective arrangement even in otherwise difficult-to-access places, such as in a caravan door frame or in a frame holder for a window/door. In addition, the at least one magnet can also be attached to a frame in difficult-to-access places simply by gluing or using magnetic force.

In order to hold the protective arrangement, which is held so as to be rotatable, in its closed position closing the opening, it can be provided that a closing magnet is formed which is arranged at a distance from the axis defined by the at least one hinge magnet, wherein the at least one closing magnet is preferably weaker than the at least one hinge magnet. Such a closing magnet is also easy to attach to a frame of the opening and is therefore easy to install. As an alternative to the closing magnet, a simple mechanical fixing device, such as a latching connection with a hook-shaped spring element for engaging behind an undercut, can be designed, which provides a fixing force for securing the protective arrangement in the closed position, wherein the force applied by the fixing device is less than the force applied by the hinge magnets for holding the protective arrangement.

The invention therefore does not exclude the provision of, for example, an additional fixing element which mechanically holds, for example, a protective arrangement designed as an insect screen door in its closed position, as long as the insect screen door is held on the frame without the further (fixing) element solely by means of the at least one magnet. Preferably, however, no further element is provided which mechanically fixes the protective arrangement to the frame.

If the at least one hinge magnet is arranged in or on the enclosure, the at least one hinge magnet is in particular attached to one side of a preferably rectangular enclosure.

If the magnets are arranged on opposite sides of a rectangular opening, the guard can be attached to the enclosure in a position closing the opening, for which purpose the guard as a whole can also be removed from the magnets without the magnets providing a hinge function.

To mechanically support the pivoting/rotating movement of the frame of the protective arrangement and/or to define the axis of rotation, that the frame (i.e. in particular components of the frame struts, such as in particular the magnetizable, curved metal rod) and/or the at least one hinge magnet have a curved surface at least in sections, the curvature of the surface guiding the rotation about the axis specified by the at least one hinge magnet. In a cutting plane aligned orthogonally to the axis, for example, the surface of the frame resting on the magnet, which preferably has a flat surface, has a circular-arc, parabolic or hyperbolic convex shape. Alternatively or additionally, it can be provided that the at least one hinge magnet has a concave (circular-arc, parabolic or hyperbolic) shaped surface (in a cutting plane orthogonal to the axis), in which a frame strut of the protective arrangement is arranged. In a further embodiment, both the surface of the at least one hinge magnet and the surface of the frame can be curved. In a preferred embodiment, a metallic rod forming the frame in one piece is elliptical or circular in cross section.

In principle, it is possible for the at least one magnet to be integrated into the enclosure. Alternatively, it can be provided that the at least one magnet is provided as a separate component, which can be attached to the enclosure, for example by gluing. If the enclosure is made of a magnetizable material or has a magnetizable element, the at least one magnet can also be attached to the enclosure based on the magnetic force alone. The at least one magnet is in particular a neodymium magnet. The at least one magnet preferably has a cuboid shape with an edge length of no more than 20 mm x 10 mm x 10 mm, particularly preferably no more than 15 mm x 5 mm x 5 mm. In this way, relatively small magnets can also be attached to hard-to-reach places.

The frame of the protective device has at least one element made of a magnetizable/magnetized material. For example, it can be provided that frame struts forming the frame have profile strips made of plastic, with an element made of a magnetizable/magnetized material being arranged at suitable locations in at least one profile strip.

However, it is preferred that the frame or the frame struts forming the frame are made of a magnetizable/magnetized material. The frame struts that give the frame its stability or the preferably one-piece frame are made of magnetizable steel or a magnetizable composite material, for example. It can be provided that the textile fabric in particular is secured to the frame struts/to the frame by means of separate clamping elements that are not made of a magnetizable material.

In a particularly preferred embodiment, the frame is formed from a one-piece, bent metal rod to which the textile fabric is attached in particular in a materially bonded manner, for example by gluing or welding, for which purpose the bent metal rod can have a coating. The rod consists in particular of steel. The frame is in particular rectangular, for which purpose the metal rod is bent in the corners by approximately 90° with the desired radius. The frame is preferably formed in a flat plane. When the frame is formed by a bent metal rod, it can also be provided that the frame is bent in a third dimension, so that the textile fabric spanned by the frame has a curvature. The metal rod preferably has a cross-sectional area of no more than 3 cm ² , preferably no more than 1 cm ² . The rod preferably has a width (parallel to the The sheet material has a width (in the plane spanned by the sheet material) of not more than 8 mm, particularly preferably not more than 5 mm, and a height (orthogonal to the plane spanned by the sheet material) of more than 8 mm but not more than 12 mm. The ratio of width to height is preferably greater than 1.5.

If the frame has several profile strips made of plastic to form the frame struts, it is particularly provided that at least one magnetizable/magnetized element is arranged in at least one profile strip. Such a magnetizable element can, for example, be a small plate which is fastened in the profile strip or attached to the profile strip.

In a preferred embodiment, the magnetizable element is designed as a rod-shaped element. In principle, a rod-shaped magnetizable element, for example a rod made of steel, can be arranged in each of the profile strips, which in particular consist of plastic. In particular, if the frame can be pivoted about the axis defined by the at least one hinge magnet, it can be sufficient if exactly one magnetizable rod extends over the entire length of exactly one profile strip made of plastic. The rod-shaped element preferably has a cross-sectional area of at least 1 cm ² . It is particularly preferred if the outer surface of the profile strip has a curvature to support the pivoting movement about the axis defined by the at least one hinge magnet.

In order to be able to arrange the frame together with the at least one magnet in a receptacle delimited by a window frame and the window sash (or by a door frame and the door sash), the frame and one of the magnets (in a plane spanned by the surface structure and the longitudinal extension direction of the The frame has a width (parallel to the plane spanned by the sheet-like structure) of not more than 12 mm (particularly preferably not more than 10 mm), but particularly preferably more than 8 mm, and a height (orthogonal to the plane spanned by the sheet-like structure) of more than 8 mm but not more than 14 mm, preferably not more than 12 mm.

In the Figures 1 to 3 a protective arrangement is shown. The protective arrangement comprises a frame 2 that surrounds/edges an opening 1. The frame 2 can be realized, for example, by a window or door frame.

The protective arrangement further comprises a protective device 3 with a frame 3.1, which spans a textile fabric 3.2. The textile Fabric 3.2 may be designed to provide protection against the penetration of insects, sunlight and/or pollen.

The protective arrangement further comprises a holding device 4 which has three hinge magnets 4.1, 4.2 and 4.3 as well as a closing magnet 5 which are attached to the frame 2.

The hinge magnets 4.1, 4.2 and 4.3 are arranged one above the other in a straight line on one long side of the frame 2. The closing magnet 5, however, is arranged on the opposite side of the opening 1 and is weaker than each of the hinge magnets 4.1 to 4.3. The magnets 4.1 to 4.3 and 5 can be glued to the frame 2 using an adhesive strip, for example. If the frame 2 is made of a magnetizable material, the magnets 4.1 to 4.3 and 5 can be held on the frame 2 solely due to the magnetic forces. The holding device 4 can thus be attached to the frame 2 very easily.

The frame 3.1 of the protective device 3 comprises at least one magnetizable element or consists of a magnetizable material. In the Figure 1 In the closed position shown, the frame 3.1, which is magnetized in sections by the hinge magnets 4.1, 4.2 and 4.3 as well as the closing magnet 5, is held by the magnetic forces alone. The protective device 3 can therefore also be attached very easily to the holding device 4 attached to the frame 2.

As in Figure 2 As shown, the frame 3.1 can be pivoted/rotated about an axis defined by the hinge magnets 4.1, 4.2 and 4.3, so that the protective device 3 can be moved from its Figure 1 shown closed position, whereby the opening position in Figure 3 is shown. In all positions, the protective device 3 is held to the frame 2 by the hinge magnets 4.1, 4.2 and 4.3.

According to a first embodiment, the frame 3.1 is formed by a magnetizable steel rod which is inserted into the Figures 1 to 3 A cross-sectional view through the frame in the area of the hinge magnets is shown in Figure 4 The frame 3.1, which is magnetized at least in sections by the hinge magnet 4.2, is pulled towards the hinge magnet 4.2. The textile fabric 3.2 is connected to the frame 3.1 by gluing or welding. The Figure 4 The noticeable curvature of the surface of the frame 3.1 supports the rotational movement of the frame 3.1 during an opening or closing process.

According to the Figure 5 In the second embodiment shown, the frame 3.1 comprises a profile strip 3.3 made of plastic, inside which a magnetizable rod 3.4 is arranged. The textile fabric 3.2 is fixed to the profile strip 3.3 by means of a clamping strip 3.5. It can be provided that the magnetizable rod 3.4 extends over the entire length of a profile strip 3.3. Alternatively, it can be provided that magnetizable rods 3.4 are arranged in the profile strip 3.3 extending over the entire length of the frame 3.1 only in the area of the hinge magnets 4.1, 4.2, 4.3. The rod 3.4, which is at least partially magnetized by the hinge magnets 4.1 to 4.3, is attracted by the hinge magnets 4.1 to 4.3.

Depending on the curvature of the profile strip, which has an omega-shaped cross-section, a rotary movement during an opening/closing process can be supported by the profile strip 3.3. However, it can also be provided that magnets are arranged on both sides of an opening 1 and that the profile strips 3.3 forming the corresponding frame struts have a magnetizable rod 3.4 in their interior, so that the The protective device 3 is held equally firmly by the magnets on both sides of the opening 1. In this case, a rotating bearing is not provided, so that the profile strips can also lie flat against the magnets.
