Description

The invention relates to a device for closing an opening, in particular door, window, flap with a (profile) frame, which forms the door which is pivotally mounted in at least one direction in an outer frame (opening frame), said door frame with at least one Return device is provided and is automatically fixed in the opening plane by magnetic forces.

State of the art

Such devices are known and are used for example in the form of folding / swing or swing doors.

Such hinged or swing doors are used, for example, as insect screens and are often constructed of light metal profiles. As a filling u. a. Fabric, plastic gazen used to prevent the ingress of insects inside the building.

Their application often find these devices in the form of so-called intent doors, which are mounted on the outside of buildings, etc. on the door frame or on the frame of the door. Such devices make it possible, on the one hand to prevent the ingress of insects, but on the other hand, to ensure easy access. Furthermore, the invention also relates to folding or swing doors and windows that provide visual and / or sun protection functions.

These devices can be designed as folding as well as swing doors, wherein the swing doors are characterized in that they can be pivoted to both sides, thus allowing easy access both from outside to inside, and from the inside out.

For closing an opening, for example by means of a door, a window or a flap, hinges are usually attached to a frame, which allow a pivoting movement. The disadvantage of this closure devices is obviously due to the fact that no automatic closure of the opening takes place. In particular, for devices such as insect screens but automatic closure of the opening must be ensured to prevent the ingress of insects.

Also known are devices which have in addition to the hinges mounted door closer. Such additional closure mechanisms are not advantageous because they add additional manufacturing and material costs and bring with them an increased weight.

In order to reduce these additional expenditures, devices are known that provide integrated reset devices that allow both pivotal movement and provide a closing function.

DE 100 34 071 describes such a return device for folding doors, in the form of a torsion bar, which moves the frame in the starting position for closing the opening.

DE 20 2005 020 describes a further integrated return device for swing doors, in which case the restoring device consists of a resilient steel plastic spring element.

Also other restoring devices in the form of spring elements such as coil springs etc, as well as combinations of two torsion bars as in DE 10 2006 005 375 described, are known.

One problem that is not taken into consideration are the very different local requirements for such devices. So it is known that the restoring forces, if they are slightly overdosed, bring with swing doors frequent penetration through the opening plane with them This unwanted pendulum motion can only be prevented by stronger magnets. It is also known that strong gusts of wind, especially in swing doors are responsible for an undesirable continuous pendulum motion. This problem can only be counteracted by stronger magnets. However, this means that either correspondingly expensive conversion measures must be carried out, or several differently strong magnetic locks or doors with different strength magnetic locks must be kept in stock, which leads to increased costs. Or the overall construction of the device becomes very massive, heavy and expensive.

The same applies to hinged doors, again very strong spring forces and strong magnets must be used to ensure a secure closure. Here oversizing must also be taken into account, which leads to higher costs and higher weight. Furthermore, oversized restoring forces bring disadvantages in handling with it. Thus, there is a risk that the door swings back too fast beats the user in the back or legs and can cause injuries in the worst case, especially with heavy doors.

Equally problematic, different climatic conditions and in particular different temperatures can affect. So it is to be expected both with a different restoring behavior, as well as with other gaps between the door element and the frame, due to the different expansion behavior of the materials involved.

It is also known that, for example, with torsion bars of the same size, which are usually prefabricated by the corresponding wholesalers, up to 15 tolerances with respect to the torsion force occur. This can lead to problems with the closing movement. Comparable tolerances of the spring forces can also occur with other spring elements.

Furthermore, the devices for closing openings are often provided with magnetic devices which have the tasks to dampen the movement of the restoring devices and to temporarily fix the door in the opening plane.

DE 10 2004 026 270 describes such magnetic closing elements, which consist of at least one first magnetic element on the frame part of a pivoting or sliding frame and a second stationary magnetic element on the door frame.

Typically, many of the proposed devices operate with brushes retracted into grooves in the profile elements that make up the door frame or door, or similar means to seal the four openings between the door and frame member, especially on the side of the magnetic closure device, against insects. as well as to close visually, so that no gap is more visible, especially in cases where due to dimensional differences in production or installation asymmetric stomata between the door and frame can occur and they are to be sealed.

These sealing measures are often combined with additionally mounted frame elements that possibly overlap at least visually appearing, not completely sealed by the brush seals columns.

A recurrent problem in this context, especially in the very frequently used solution of brush materials, is the insufficient effect of these sealing solutions, especially in the case of non-parallel gaps which are to be closed. Due to the stiffness of the individual bristles in the entirety, the material properties of the brushes result in a strong unwanted braking effect during the closing movement, which is why it is often not possible to completely close the occurring, in particular asymmetrical, stomata

A supplementary general problem continues to be that by known solutions, also due to the reasons described above, such. B. high weight and solid construction, as well as by the previously found sealing solutions, the clear passage width which is given by the outer frame element in the case of intent doors, is relatively greatly reduced. In particular, additionally attached frame elements for optical sealing reduce this passage width.

Another problem is that many of the solutions cited, because of their structure, the proposed connections between the frame and door element, as well as their high weight are not easy to install and user-friendly, especially when it comes to quickly and easily unhook the door and unmount.

None of the proposed solutions succeed in describing a device which provides a closing force corresponding to the respective circumstances and at the same time describes a temporary, in particular magnetic closing device which at the same time dampens the movement of the return devices, fixes the device in the opening plane and additionally a sealing function provides against invading insects, and is easy to install.

task

The invention has for its object to develop a device of the type described above, which avoids the disadvantages mentioned, wherein both at least one closing force generating return device is described as well as a attracting effect, in particular magnetic effect, based closure device is shown, in addition provides a sealing function against insects and dirt to the occlusive and damping properties.

This object is achieved in conjunction with the preamble of claim 1 according to the invention by the characterizing features of claim 1.

Surprisingly, it has been found that an adjustability of at least one restoring device makes it possible to achieve an optimum closing behavior adapted to the respective circumstances, both in terms of speed of closing movement and closing force to achieve. Thus, the cost of materials, the manufacturing cost and the weight of the overall device can be kept as low as possible. In addition, a particularly advantageous embodiment of the invention designed so that the adjustment of the restoring forces is very easy to install, since this setting can be made in the already installed state.

The hitherto unused idea of using the magnetic closure system present in virtually all known devices as a sealing system also offers a number of considerable technical advantages, which are otherwise always achieved by means of complementary sealing devices in the form of brushes, etc., as well as often complementary devices which reduce the clear passage width , were very elaborate and not satisfactorily resolved.

To solve the problem is provided in the inventive device for automatically closing an opening that between the door and door frame at least one spring element is mounted, which is stretched when the door is opened and the door is released back into the opening plane when you release the door by the stored energy , In order to ensure a variable closure force which takes into account the respective requirements, at least one spring element is constructed so that its closing force, when installed, can be adjusted so that the spring force can be adapted to the requirements. This can be achieved in an advantageous embodiment in that at least one of the spring elements is a torsion bar, which is firmly fixed on one side, but can be adjusted by a possible displacement of the second fixing point to the respective required closing force.

An advantageous solution can be designed such that, in a first, for example upper spring element to a steel plastic spring element with inclined turret and an elastic plastic spring package or cup spring package as in DE 20 2005 020 194 described and the second spring element to an adjustable torsion bar combined with a magnetic closure system, which consists of at least one movable magnetic element, for example, attached to the door frame, and at least one further magnetic element, which is attached to the zero position opposite the door frame portion of the door is.

In this case, in an advantageous embodiment, the first spring element used above in the guide profile of the door, which is formed from an elastic plastic spring element, assumes the task of ensuring, so to speak, the "basic control", and thus the actual closing movement. the second introduced in this embodiment below in the guide profile spring element, which is formed by an adjustable torsion bar can be adjusted depending on the individual circumstances on the ground in the already suspended state that the additional required closing force is provided, the principle of force regulation on the between two fixing points existing clear length of the torsion bar is regulated, with a short distance between the fixing points more opening force is required for the door to twist the torsion bar, correspondingly larger is the stored spring force, which can then be discharged again from the twisted torsion bar to close the door again. However, it is advantageous, in particular for swing doors, when the spring force is not chosen to be too large. So choosing a slightly longer length between the two fixing points, this has the advantage that no very strong magnets are needed to fix the swinging door immediately, ideally at the first swing in the opening plane. In particular, the proposed combination of two spring elements is also ideal for quick and easy installation and removal of the door. The proposed system is both easy to install and user-friendly.

In order to prevent too fast closing of the door and thus the risk of being injured by slamming the door, it has surprisingly been found that in addition to at least one return device, which is responsible for closing the door, at least one additional device can be added to counteract the restoring forces when needed and thus to dampen the closing movement of the door, at least over a certain range of the total closing movement. Here, for example, a spring element can be used, which counteracts the restoring forces which generate the closing movement of the door in the opening plane, that its spring force acts opposite, ie counteracts a certain part of the closing force. In a particularly advantageous embodiment, this device can also be designed such that it is adjustable, in particular adjustable in the installed state, designed. Advantageously, this device can be completely or partially integrated in the door element. Surprisingly, it has been found that an advantageous embodiment of the complementary magnetic closure system according to the invention, which consists for example of an edge profile forming the frame, which is formed in this particular case of two mutually and in each other extending profiles, in particular U-profiles, by means of a permanent magnet and a magnetizable element adhere to each other, both the task of holding the door in the closed position, the damping of the restoring forces, but also can provide a sealing function, which is also also suitable to reliably close uneven gaps between door and frame.

Advantageously, a frame element which forms the outer door frame for the door movably mounted therein with at least three other frame elements is attached vertically to the door frame on the locking side. Preferably, a slightly wider, ideally closed at the top and bottom U-profile, at the inner rear side is a magnetizable metal device, in particular a metal strip mounted, either a running over the entire length of the outer U-profile metal strip or cost reasons, for example three magnetizable metal bands, preferably above, below and in the middle are needed, if necessary and depending on the particular dimensions present, more or fewer metal bands or magnetizable or magnetic devices can be used.

On the inside of an inner likewise vertically extending U-profile, which is mounted movably, preferably predominantly horizontally displaceable in the outer U-profile is fitted, in the metal devices opposite areas, preferably above, below and in the middle several, advantageously the same number of magnets, attached. For example, so that they face the magnetizable metal bands, these form the mutually attractive contact points.

Likewise, a corresponding number of magnets are fitted into the door elements, advantageously in the otherwise usually provided for the brush groove, that they are also mounted on the same areas of the magnets, the contact points of the inner U-profile with the door closed. In a particularly advantageous embodiment, the magnets on the inside of the inner, movable U-shaped profile on a stronger magnetic attraction, as opposed to them with the door closed magnets in the door element. This ensures that after opening the door, by the magnetic force of the stronger magnets, the inner, movable U-profile always immediately due to the magnetic interaction with the metal strip of the outer U-profile creates a sufficient magnetic attraction, which both profiles, the outer U-profile and the sliding inside U-profile, pulls together and holds reliably in this position until the door is closed again and the resulting greater magnetic attraction between the magnet of the inner U-profile and the magnet , which are mounted in the door element, the inner U-profile slides horizontally back toward the door, thereby both dampens the closing movement, and the gap between the door and frame completely closes and seals by the magnets of the inner U-profile with the magnets interact with the door and thereby pull the profile against the door leaf to achieve the always flush sealing of the device.

Due to the main, but not exclusive horizontal sliding direction of the inner U-profile, also any existing differences in the width of the door gap can be reliably and completely sealed sealing.

By the magnets of the inner U-profile, which are attracted by the attached to the inside of the outer U-profile metal strip, the movable inner U-profile is held reliably.

Of course, the above solution can be used for all four joints between door and frame, replacing the otherwise primarily used brush seals. Particularly advantageously, this solution is used for the joints that occur at the top between the door and door frame and the side to which the magnetic closure is usually attached.

In order to avoid any resulting noise when closing the door at the flush meeting of the two metal elements, ie the inner, movable U-profile and the profile of the door element, various advantageous embodiments are possible. Thus, for example, a thin, elastic sealing medium, in particular a sealing tape, which is glued, for example, or inserted into a prepared groove in the movable U-profile, is particularly well suited to damp a possibly resulting shutter noise. Alternatively, of course, other sound-absorbing materials can be used. Such media have only the task of attenuating any resulting noise and are not needed to seal the door gap against insects or dirt. This function reliably takes over the magnetic locking device according to the invention.

In a further advantageous embodiment, a restoring device can be used, for example, the above-mentioned disc spring element, steel plastic spring element can be used with tilted turret and in the lower part as a return device. A particularly advantageous embodiment provides that the inclined turret no straight plan Forms surfaces that are rotated against each other and thus the rotational movement and, for example, based on a suspension element on a part of the turret generate the restoring forces, but have a curved shape. In particular, a sinusoidal surface has been found to be advantageous. This shaping makes it possible for the two inclined surfaces of the rotary head to slide past each other in a particularly gentle manner, thereby significantly improving the wear of the material, and to effect a softer displacement of the two surfaces relative to each other. Another return device may, but need not, be used, particularly when providing a sealing function that simultaneously provides soft, smooth cushioning. Such a sealing function can be achieved for example in the form of a sealing tube as described below.

If required, the device according to the invention can of course be supplemented by additional functions, for example by devices which allow the temporary closing of the door, in the simplest case by means of a key and lock, but advantageously also by means of a supplementary magnetic closure solution, for example by magnetisable and displaceable devices mounted in the door leaf Advantageously, bolts, combined with holes for the bolts in the opposite frame member, for example in the moving part of the vertical sealing rail. By means of a magnetic key, these movable bolts can then be positioned in the holes, thereby permanently closing the door. These and similar closure solutions are suitable, for example, as reliable wind / storm protection, as well as a transit barrier

An advantageous, further possible solution, which is best suited for damping the closing movement and sealing all occurring between door and frame joints can be achieved by a flexible device, for example consisting of a weather-resistant and abrasion-resistant material, advantageously silicone, which in an advantageous embodiment in Form of a cylindrical material, in particular in the form of a tube is used. The solution described below is used in particular to solve the problem of mostly very reduced passage width, which occurs primarily in insect screens and windows. Thus, this special solution provides the ideal prerequisite to achieve the greatest possible passage width, on the other hand, an advantageous, hardly space-demanding solution is proposed by the solution described below for sealing the joints, as well as possibly occurring dimensional differences between the door and frame. In a particularly advantageous embodiment, a silicone tube with a wall thickness between 0.6 mm and 0.7 mm is used as the sealing material as a flexible seal. This seal can be used for one, several or preferably for all four joints between the door and frame. An advantageous variant is likewise to combine this solution with a magnetic closure solution, as in the abovementioned solution. In this case, for example, already in the door profile, as well as on the likewise desired sides of the opening frame, but in particular in the region of the locking side, existing groove, which is often used for attachment of brush materials, be used so that this groove on all four sides advantageously with magnets or magnetizable device is provided, which can be additionally used on the closure side for fixing the door in the frame and damping the restoring forces, on the other hand, in addition to ensure the flexible sealing of all four gaps occurring between door and frame. In order to advantageously achieve the solution proposed for four sides of the door by means of silicone hose, it is proposed, on all four sides of the door, which are opposite the frame, a suitable number of magnets flush with the door profile or something deepened, for example in a groove or Comparable to introduce and fasten. A silicone tube, with a diameter which is large enough to ensure an all-round seal, preferably 10 mm, and a wall thickness of preferably 0.6 to 0.7 mm in order to ensure a correspondingly elastic behavior, by means of or a plurality of magnetizable elements, preferably a stainless, polygonal, in particular four-edged metal rod, which in an advantageous embodiment, the same length as the corresponding silicone tube and a width of about 2 mm × 1.5 mm to about 3 mm × 3.5 mm , and in these inserted reliably held over the magnetic elements in the door profile. On the one hand it serves the stability of the sealing solution, since the silicone hose is very soft, on the other hand he holds it reliably at the desired position on the door profile. On each side of the door profile, such a combination of magnets, silicone hose and metal rod can be attached, so that a seal of all four sides is guaranteed. Since the silicone tubes can be opened at their ends, during the sealing process, the hose can be compressed in accordance with the joint distances that occur and the air can escape accordingly, so that a sealing closure between the door and the frame is always ensured. Of course, a circumferential silicone hose can be selected if z. B. is ensured by perforations, etc., that the air can escape if necessary, to adapt to the gap to be bridged is achieved. By this kind of Attachment of the silicone tube is provided a solution that has both a reliable sealing effect, but at the same time provides a closure function, optimizes the clear passage width and ultimately holds the actual sealing material without material damage reliable. Of course, alternative solutions that solve the same tasks can also be used. An advantageous embodiment of this invention is in the 4a and 4b described.

Surprisingly, it has been found that several previously unsatisfactorily solved disadvantages of the prior art could be solved in a cost-effective, simple and reliable manner with this solution.

Thus, both a reliable, asymmetric seal is guaranteed on all four sides, at the same time, the door passage width and height is only slightly reduced and no additional elements, such as additional devices needed. In addition, due to the elastic properties of the material used, an undesired braking effect, as is usual, for example, with rigid brushes, is prevented. In a special embodiment, however, this solution can also be used to dampen restoring forces.
