The invention relates to a door system with a non-folded door leaf on which at least two hinge barrels are fixed on one side, and with a frame having two vertical legs, one of which bears pivot hinges for the barrels.
In some countries, in particular in Eastern Europe, so-called butt joint door systems are frequently used, wherein the door leaf has no fold.
It is an object of the invention to provide a door system of this type which can be manufactured and mounted more efficiently.
In order to achieve this object, according to the invention, the hinges are arranged symmetrically in height relatively to a horizontal center plane of the frame, and fixing devices for fixing the barrels on the door leaf and for fixing the hinges on the frame each have a 180° rotational symmetry relative to a horizontal axis.
Thanks to the rotational symmetry of the fixing devices it is possible to mount the barrels on the door leaf in two positions rotated by 180° relative to one another. Likewise can the hinges be mounted in two positions rotated by 180° against one another on the corresponding frame leg. This permits to use one and the same door system selectively for a right side hinged door and a left side hinged door. If the door is to be mounted as a right side hinged door, then the positions of the two vertical frame legs are interchanged in comparison to the mounting situation for a left side hinged door. Moreover, these legs are mounted with inverted orientation, so that the ends that face upwards for a left side hinged door will face downward for a right side hinge door. Would the arrangement of the hinges be left unchanged, this would have the consequence that the pivots of the hinges would point into the wrong direction, i.e. downwards. This, however, can be corrected by mounting the hinges in the reversed position, so that the pivots point upwardly again. Due to the symmetric arrangement of the hinges and the related parts of the fixing devices relative to the horizontal center plane of the frame, it is assured that the hinges will be in the same height for both a right side hinged door and a left side hinged door.
For a right side hinged door, the door leaf is mounted in a position rotated 180° about the vertical center axis in comparison to the mounting situation for a left side hinged door. Since the door leaf does not have a fold, it fits with the frame even in this rotated position. However, the rotation has the consequence that the barrels, in particular the eyelets thereof, project to the wrong side relative to the plane of the door leaf and therefore do not match with the positions of the pivots. Again, this may be corrected by mounting the barrels in a position rotated by 180°.
Thus, the invention also permits a method for converting a right side hinged door into a left side hinged door and vice versa, the method comprising the following steps:
In this method, the order of the first three steps is arbitrary.
Useful details and further developments of the invention are indicated in the depending claims.
According to an independent aspect of the invention which may however be combined with the solution described above, the frame has a door post and a door case that are connected to one another by a bracket arranged on the outward side of the door post. The bracket and the outward surface of the door post form a gap into which a part of a door case may be inserted such that it is self-lockingly held by the bracket. In a preferred embodiment the door case is itself composed of two parts which may be inserted underneath the bracket from opposite sides. In another embodiment the door case may be composed of three parts, i.e. two blinds and a sheathing for the jamb of the door opening. In this case one of the blinds and the sheathing may be held by means of the bracket whereas the second blind is adapted to be connected to the sheathing by means of a snap-in profile. The sheathing which is essentially plate-shaped may be weakened along one or more vertical lines so that it can be adapted to different thicknesses of the wall by breaking or cutting along these lines.
The vertical legs and a horizontal top leg of the door frame are preferably connected by miter joints. To that end, connecting elements may be used, preferably of metal, which have the form of angle brackets the legs of which each have a trapezoidal profile that is open on the shorter side of the trapezoid. Then, the legs of the angle bracket may be inserted into complementary profiles of the horizontal leg and one vertical leg of the frame so as to form a stable corner joint.
In a particularly useful embodiment the vertical legs and the horizontal legs of the door post are pre-mounted in the door opening after they have been connected to one another. For that purpose, tightening fittings are used which pass through the horizontal leg of the door post and each of which carries at its top end a support plate which may be tightened, by means of a screw thread for example, against the inner surface of the door opening. Since the lower ends of the vertical legs of the door post are supported on the floor, the door post is stably mounted in the door opening while still being disposed at a certain distance from the jamb surfaces of the door opening. The gap between the door post and the jamb surfaces may be filled with expanding foam material before this gap is covered by means of the door case. The provisional mounting of the door post by means of the tightening fittings is so stable that the door leaf may be suspended before the foam material has expanded and cured. In this way, the door leaf may reinforce the door post and support it from inside, so that the force of the expanding foam may be better absorbed. Preferably, thin strips are adhered to the edges of the door leaf, these strips serving as spacers and determining the width of the rabbet between the door leaf and the frame. When the foam material has cured, the strips are removed, so that the door leaf will have equal play on all sides.
This method of mounting the door can also be taken advantage of independently of the features of claim 1.
An embodiment example will now be described in conjunction with the drawings, wherein:
The door system which has been shown in a schematic exploded view in
As is shown in
The fixing devices 22 and 28 for the barrels 20 and the hinges 24 are respectively formed by two bores in the door leaf 10 and the leg 14, respectively, in which bolts of the barrel 20 and the hinge 24 are inserted, respectively, in this example. In
If desired, a right side hinged door may be formed with the components of the door system shown in
As is shown in
Moreover, in the transition from
However, the fixing devices 22 and 28 for the barrels 20 and the hinges 24 each have a 180° rotational symmetry, so that the barrels and the hinges may be mounted at the door leaf 10 and at the leg 14, respectively, in two positions rotated by 180°. It is therefore possible to mount the hinges 24 in inverted position, so that their pivots 26 point upwardly again, and to mount the barrels 20 also in inverted position, so that the eyelet 30 is centered again on the pivot 26. In this way, one obtains the configuration of a right side hinged door as shown in
On one vertical edge of the base plate 32, a web 38 has been formed which carries at its free end the eyelet 30 that has the shape of a vertical cylinder.
The hinge 24 has an essentially cylindrical support body 40 with a non-threaded bolt 42 and a threaded bolt 44 projecting therefrom at right angles. The threaded bolt 44 is rotatably supported in the support body 40 and has an internal hexagon 46, so that the threaded bolt may be screwed into the corresponding bore of the leg 14 whereas the non-threaded bolt 42 is inserted in the other bore of the leg.

Similarly, the non-threaded bolt 42 and the threaded bolt 44 are arranged symmetrically with respect to an axis F, so that the hinge 24 can also be mounted at the leg 14 in two positions rotated by 180° relative to one another. The support body 40 may also be configured symmetrically with respect to the axis F, so that the top end face in
A metal bracket 52 with two symmetric wings is fixed on the outward side of the leg 14 facing the masonry 50. A center part of the bracket 52 engages the leg 14 and is fixed thereat with a plug 54 that penetrates the bracket 52 with a harpoon strip and is immobilized in a slot of the leg 14. The two wings of the bracket 52 are formed at their outer ends with flanges 56 that are bent back by more than 90° towards the leg 14 and form, together with the leg 14, a respective slot into which parts of the door case 48 may be inserted.
In the example shown, the door case 48 is composed of three parts, i.e. a sheathing 58 that covers the jamb of the door opening, and two identical blind profiles 60 that straddle the masonry 50.
The sheathing 58 is formed by a plate that is prolonged at the edge facing the leg 14 of the door post by a thinner web 62. This web has been pushed through the slot formed between the flange 56 and the bracket 52 and against an abutment 64 which is held in a groove of the leg 14. The flange 56 of the bracket 52 clamps the web 62 in the slot, and, due to the position of the flange 56 angled by more than 90°, a self-locking effect is obtained if one attempts to withdraw the web 62 from the slot, upwards in

The blind profile 60 has two dovetail grooves 72 on its inner side. The clamp profile 68 has a dovetail profile complementary to and inserted into one of the dovetail grooves 72. In this way, the clamp profile 68 is fixed at the blind profile 60. Then, the clamp profile and the blind profile may be snap-fastened at the edge of the sheathing 58, with a nose formed by the clamp profile 68 snapping-in behind the bulge of the tongue 70. The clamp profile 68 may for example be an elastic hollow profile of plastic or metal.
The sheathing 58 may for example be a plate of wood or timber product, e.g. fiberboard, and is, in this example, weakened on the side facing the masonry 50 by several grooves 74 that extend in parallel with the edge formed by the web 62. If the masonry 50 has a smaller thickness and, consequently, a sheathing with a smaller width is needed, then a part of the sheathing can be broken away at one of the grooves 74. Then, one or more of the webs 76 formed between the grooves 74 is cut away, with a broach for example, so that the edge of the plate is formed again a thinned web which may be inserted into the slot delimited by the clamp 52 in order to fix the sheathing at the leg 14 of the door post.
In general, the door frame 12 will comprise not only the two vertical legs but also a horizontal top leg that interconnects the two vertical legs. This top leg may also comprise a door post leg and a door case leg which will be formed of the same profiles as in
In
What will now be described is a method by which the door system that has been disclosed here can be installed in a door opening in a particularly efficient and safe way.
At two points, preferably near the opposite ends, the horizontal leg 86 is penetrated by two tightening fittings 88. A single tightening fitting 88 has been shown in a perspective view in
