Definitions

  • 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.
  • Such devices are known and are used for example in the form of folding / swing or swing doors.
  • hinged or swing doors are used, for example, as insect screens and are often constructed of light metal profiles.
  • plastic gazen used to prevent the ingress of insects inside the building.
  • 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.
  • hinges are usually attached to a frame, which allow a pivoting movement.
  • this closure devices is obviously due to the fact that no automatic closure of the opening takes place.
  • devices such as insect screens but automatic closure of the opening must be ensured to prevent the ingress of insects.
  • 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.
  • 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.
  • Swivel or sliding frame consist and of a second stationary magnetic element on the door frame.
  • 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.
  • 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.
  • 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.
  • an adjustability of at least one return device makes it possible to achieve an optimum closing behavior adapted to the respective circumstances, both with respect to the speed of the closing movement and the closing force.
  • the cost of materials, the manufacturing cost and the weight of the overall device can be kept as low as possible.
  • 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 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 ,
  • 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.
  • 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.
  • 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 so to speak, the "basic control", and thus to ensure 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, depending on the individual circumstances on the ground in the already suspended state can be adjusted so that the additional required closing force is provided
  • the principle of the power regulation is regulated by the between two fixing points clear length of the torsion bar, with a short distance between the fixing points more opening force is required for the door to twist the torsion bar, which is correspondingly larger stored spring force, which can then be returned by the twisted torsion bar to close the door again.
  • 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.
  • 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.
  • this device can also be designed such that it is adjustable, in particular adjustable in the installed state, designed.
  • this Device wholly or partially be integrated into the door element.

  • 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.
  • 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.
  • 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.
  • a corresponding number of magnets are fitted in the door elements, advantageously in the otherwise usually provided for the brush groove, that these also on the same areas of the magnets, the contact points of the inner U-profile are opposite with the door closed.
  • the movable inner U-profile is held reliably.
  • the above solution can be used for all four joints between door and frame, replacing the otherwise primarily used brush seals.
  • 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.
  • 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.
  • 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.
  • a restoring device can be used, for example, the above-mentioned disc spring element, steel plastic spring element are used with an inclined turret and in the lower part as a return device.
  • the inclined rotary head does not form straight, flat surfaces which are rotated against each other and thus generate the rotational force and, for example based on a suspension element on a part of the rotary head, the return forces, but have a curved shape.
  • 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, and as a result the material wear can be significantly improved, and a softer displacement of the two surfaces relative to one another is effected.
  • 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.
  • 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 complementary magnetic closure solution, for example by mounted in the door leaf magnetizable and movable devices, advantageously bolts, combined with holes for the bolts in the opposite frame element, for example in moving part of the vertical sealing rail.

  • 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.
  • 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.
  • 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.
