Description

DOOR SYSTEM

The invention relates to a door system with an unfolded door leaf, to which at least two bands are fastened on one side, and to a frame with two vertical legs, one of which carries angling for the bands.

In some countries, especially in the Eastern bloc, so-called butt joint door systems are common in which the door leaf has no fold.

The object of the invention is to provide a door system of this kind, which can be manufactured and assembled more efficiently.

This object is achieved in that the hinges are arranged in height symmetrical to a horizontal center plane of the frame and that fastening means for fixing the bands on the door panel and for fixing the hinges on the frame each have a 180 ° rotational symmetry with respect to a horizontal axis.

Due to the rotational symmetry of the fasteners, it is possible to mount the bands in two rotated by 180 ° to each other positions on the door leaf. Likewise, the fishing can be mounted in two rotated by 180 ° to each other positions on the associated frame legs. This allows one and the same door system to be used optionally for a right door or a left door. If the door is to be installed as a right door, then the positions of the two vertical frame legs are reversed compared to the installation situation in a left door. In addition, these legs are mounted in the reverse orientation, so that the ends facing upwards in a left-door, at the right door facing down. With unchanged arrangement of the fishing, the result would be that the journals of the fishing point in the wrong direction, namely down. However, that can be corrected. by mounting the hinges in the reverse position so that the journals are facing upwards again. Due to the symmetrical arrangement of the hinges and the associated parts of the fasteners with respect to the horizontal center plane of the frame is then ensured that the hinges are at the right door at the same height as the left door.

In the case of a right-hand door, the door leaf is mounted in a position rotated by 180 ° about the vertical center axis compared to the installation position of the left-hand door. Since the door leaf has no fold, it fits in this rotated position in the door frame. However, the rotation also has the consequence that the bands, in particular their eyes, with respect to the plane of the door leaf to the wrong side and therefore do not match the positions of the journals of the hinges. However, this can also be corrected by mounting the bands in the 180 ° rotated position.

The invention thus also allows a method for converting a right door to a

Link door and vice versa, with the following steps:

Interchanging the left and right vertical legs of the frame and mounting these legs in a position where top and bottom are reversed, reversing the attachment position of each tang,

Reversing the mounting position of each band on the door leaf, and

Hooking the door leaf into the hinges in a rotated by 180 ° about the vertical center axis position. The order of the first three steps is arbitrary.

Advantageous embodiments and further developments of the invention are specified in the subclaims. According to an independent aspect of the invention, however, which can be combined with the solution presented above, the frame has a door frame and a chuck, which are interconnected by a frame outside the door frame mounted bracket. In this case, the clamp with the outer surface of the door frame forms a gap into which a portion of the chuck can be inserted so that it is held by the clip self-locking. In an advantageous embodiment, the lining in turn consists of two parts, which can be pushed from opposite sides under the clip. In a further embodiment, the lining may consist of three parts, namely two frame and a clothing for the reveal of the door opening. In this case, one of the frame and the clothing can be held by means of the clip, while the second frame is connectable by a locking profile with the clothing. The substantially plate-shaped clothing can be vorgewächt along one or more vertical lines, so that they can be adjusted by canceling or cutting these lines to different thicknesses of the masonry.

The vertical legs and a horizontal upper leg of the frame are preferably mitred together. For this purpose, one can use fasteners, preferably made of metal, which have the form of angles whose legs each have a trapezoidal, on the shorter side of the trapezoid open profile. The legs of the angle can then be inserted into complementary profiles of the horizontal leg and a vertical leg of the frame, so that a stable corner connection is made. In a particularly advantageous embodiment, the vertical leg and the horizontal leg of the door block, after they have been connected to each other, pre-assembled in the door opening. For this purpose, tension fittings are used, which pass through the horizontal leg of the door frame and each carrying at the upper end of a support plate, with which they, for example by means of thread against the Innenflä- the door opening. Since the lower ends of the vertical legs of the door block are supported on the floor, the door frame is stably mounted in the door opening in this way, but it still has a certain distance to the soffit surfaces of the door opening. In the space between the door frame and the Leibungsflächen can then be introduced a swelling foam, before this space is covered with the help of the lining. The temporary fixing of the door frame with the help of the clamping fittings is so stable that the door can be hung before the swelling foam has swelled and hardened. In this way, the door leaf stiffen the door sill and supported from the inside, so that the force of the swelling foam can be better absorbed. Preferably, the edges of the door leaf are previously stuck with thin strips, which act as spacers and determine the width of the joint between the door leaf and the frame. After the swelling foam has cured, the strips are removed so that the door leaf has even air on all sides.

This method of mounting the door can also be used independently of the features of claim 1 with advantage.

In the following an embodiment will be explained in more detail with reference to the drawing.

Door frame, which is fixed with clamping fittings; and

Fig. 15 is a perspective view of a clamping fitting. The door system shown schematically in an exploded view in Fig. 1 has an unrebated door leaf 10 and a frame 12, of which only two vertical legs 14, 16 of a door jaw are shown. The door leaf 10 has on the right side of a pawl 18 and on the left in Fig. 1 side two bands 20, which are fastened with corresponding fastening means 22 at the edge of the door leaf. On the associated leg 14 of the frame fishing 24 are attached to which the door leaf can be hung with the bands 20. For this purpose, as is common practice, each tang 24 has an upwardly projecting bearing journal 26 which engages in an eye of the respective band 20.

As shown in FIG. 2, the door leaf 10 has a rectangular cross-section without folds, while the legs 14, 16 each have an L-shaped cross-section and thus form a fold, strikes the door leaf with its blunt edges. In Fig. 2 can also be seen fastening means 28 for the fishing 24th

The fastening devices 22 and 28 for the bands 20 and the hinges 24 are each formed in the example shown by two holes in the door leaf 10 and the leg 14, engage in the corresponding bolts of the belt 20 and the fishing rod 24. In Fig. 1, the center between the two pins of the fishing rod 24 is marked by a dash-dotted horizontal line A respectively. Another dash-dotted horizontal line B marks the height of the centers of the two legs 14, 16 and thus a horizontal center plane of the frame 12. The two lines A are symmetrical to this center plane. With the components of the door system shown in Fig. 1 can optionally install a right door. To illustrate the manner of mounting a right door, Figs. 3 and 4 show an intermediate stage in a conversion of the link door of Fig. 1 in a right door according to FIGS. 5 and 6. As shown in FIG. 3, on the one hand, the positions of the two legs 14, 16 are reversed. In addition, the legs are mounted in reverse position, so that the ends, which are the upper ends in Fig. 1, in Fig. 3, the lower ends. In the leg 14, this can be seen from the fact that in Fig. 3, the journals 26 have the hinges down. This transformation corresponds to a rotation of the frame 12, so in particular of the two legs 14, 16, about an axis C, which is marked in Fig. 1 and 3 by a dash-dotted cross and runs at the height of the line B perpendicular to the plane. Due to the symmetrical arrangement of the hinges 24 with respect to the line B, the lines A in FIG. 3 are at the same height as in FIG. 1.

In addition, in the transition from Fig. 1 to Fig. 3, the door leaf 10 has been rotated by 180 ° about its vertical center axis D, so that in Fig. 3, the pawl 18 is located on the left side, while the bands 20 on the right side are located. However, in this position, the door leaf can not be hung in the fishing 24 yet. The reason is that the bands 20 each have an eye 30 which receives the bearing pin 26 of the tang and which is arranged asymmetrically on one side of the door leaf. As shown in Fig. 4, this eye 30 is in the state shown in Figs. 3 and 4 on the wrong side. However, the fasteners 22 and 28 for the bands 20 and 24 have the hinges each a 180 ° rotational symmetry, so that can be fixed in two rotated by 180 ° positions on the door leaf 10 and the leg 14, the bands and fishing. It is therefore possible to mount the hinges 24 in the reverse position, so that the position pins 26 are facing upwards again, and also to mount the bands 20 in the reverse position, so that the eye 30 is centered again on the bearing pin 26. In this way, the right door configuration shown in Figs. 5 and 6 is obtained.

Fig. 7 shows a perspective view of a door hinge, which is formed by one of the bands 20 and the associated tang 24. The band 20 has a base plate 32 projecting from the two threadless bolts 34, which together with corresponding holes in the door leaf form the aforementioned fastening device 22. Additional screw holes 36 allow the base plate 32 to be securely but releasably secured to the edge surface of the door panel 10 while the pins 34 engage the associated holes and securely receive the weight of the door panel.

To a vertical edge of the base plate 32, a web 38 is attached, which carries at the free end of the eye 30, which has the shape of a vertical cylinder.

The tang 24 has a cylindrical supporting body 40, from which a threadless bolt 42 and a threaded bolt 44 exit at right angles. The threaded bolt 44 is rotatably mounted in the support body 40 and has a hexagon socket 46, so that the threaded bolt can be screwed into the corresponding bore of the leg 14, while the smooth bolt 42 dips into another bore of the leg.

In the plan view in Fig. 8, the threaded bolt 44 and one of the bolts 34 of the belt 20 can be seen, while the other bolt 34 and the smooth bolt 42 are hidden here.

In the exploded views in FIGS. 9 and 10, one recognizes the bearing pin 26 of the tang 24 in a position in which it is aligned with the eye 30 of the band 20.

In Fig. 10 it can also be seen that the band 20 including the pins 34 is formed symmetrically with respect to an axis E. If the tape is rotated through 180 ° about this axis E and the bolts 34 are inserted again into the corresponding holes of the door leaf, therefore, the eye 30, in particular its lower end face, the same height as before. , C) _

Accordingly, the smooth bolt 42 and the threaded bolt 44 are arranged symmetrically with respect to an axis F, so that it is also the Angel 24 can be secured in two 180 ° to each other rotated positions on the leg 14. Also, the support body 40 may be formed symmetrically to the axis F, so that in Fig. 10 upper end face, which carries the bearing pin 26 and forms the support for the lower end face of the eye 30, in Fig. 5 in the same Height is as in Fig. 1. However, this arrangement is not mandatory. It is only necessary that a possible height offset, which occurs at the transition from Fig. 1 to Fig. 5 at the upper end face of the support body 40 is compensated by a corresponding height offset of the lower end face of the eye 30 during the repositioning of the belt 20. Under these conditions, it is ensured that the door leaf 10 has the same height relative to the door frame both as a right door and as a left door.

Fig. 11 shows in a horizontal section one end of the door leaf 10 with the band 20 in the hinged position and with the door closed together with a complete door frame, in addition to the leg 14 of the door frame still a lining 48, which is a door opening limiting masonry 50 surrounds.

On the masonry 50 facing outer surface of the leg 14, a clamp 52 is attached made of metal, which has two symmetrical wings. A central portion of the clip 52 abuts against the leg 14 and is attached thereto by means of a plug 54 which engages the clip 52 with a harpoon web and is fixed in a slot of the leg 14. The two wings of the bracket 52 have at the free ends on flanges 56 which are bent back by more than 90 ° in the direction of the leg 14 and each form a slot with the leg 14, can be inserted into the parts of the liner 48. In the example shown, the lining 48 is composed of three parts, namely a garment 58 which covers the reveal of the door opening, and two identical frame profiles 60 which surround the brickwork 50. The clothing 58 is formed by a plate which is extended at its the leg 14 of the door handle facing edge by a thinner web 62. This web is pushed by the limited by the flange 56 of the bracket 52 slot against a stop 64, which in turn is held in a groove of the leg 14. By the leg 56 of the clip 52 of the web 62 is clamped in the slot, and due to the angling of the flange 56 by more than 90 ° results in a self-locking fixation, when trying to the web 62 upward in Fig. 11 from the To extract slot.

In a corresponding manner, a web 66 of the bottom frame profile 60 in FIG. 11 is also held on the other wing of the clamp 52.

The upper frame profile 60 in FIG. 11 is connected to the clothing 58 by a clamping profile 68. The clothing 58 forms on the side facing away from the masonry at the edge of a shallow groove which receives the web 66 of the frame profile flush. This groove is bounded by a spring 70, which forms a locking bead for the clamping profile 68.

The frame profile 60 has two dovetail grooves 72 on the inside. The clamping profile 68 has a complementary dovetail-shaped profile region which is inserted into one of the dovetail grooves 72. In this way, the clamping profile 68 is attached to the frame profile 60. The Klemmpro fil and the Blendrahmenpro fil can then lock with the edge of the clothing 58, wherein a nose formed by the clamping profile 68 over the bead of Fe. the 70 slides away. The clamping profile 68 may be, for example, a self-elastic hollow profile made of plastic or metal.

The garment 58 is provided, for example, by a panel of wood or a wood material, e.g. formed in the example shown on the masonry 50 side facing by a plurality of grooves 74 which extend parallel to the edge formed by the web 62. If the masonry 50 has a smaller thickness and consequently a clothing with a smaller width is needed, then at one of the grooves 74 a piece of the clothing can be broken. One or more of the remaining between the grooves 74 ribs 76 is then pricked away, for example, with a pry bar, so that at the edge of the plate again receives a thinned web that can be inserted into the limited by the clip 52 slot to the clothing on the leg 14 of the door jamb. As a rule, in addition to the two vertical legs, the frame 12 will also have an upper horizontal leg connecting the two vertical legs. This upper leg can also comprise a door frame leg and a lining, which can be formed from the same profiles as in FIG. 11. At the corners, the frame profiles are then set against one another and connected to each other with miter.

Fig. 12 shows an elbow 78, preferably made of metal, which can be used to fix and reinforce the miter connection between two of the frame profiles 60. The elbow has two legs 80 extending at right angles to one another, which are each bent into a flat, trapezoidal profile, the shorter (in Fig. 12 lower) side of the trapezoid is missing. The obliquely converging flanges 82, which form the flanks of the trapezoid, are each serrated on the lower edge in FIG. 12. In Fig. 13, a vertically extending Blendrahmenpro fil 60 is shown in section, while one end of a mitred thereto attached, horizontally extending Blendrahmenpro fils 60 'is shown in a view from below (with a view of the web 66). The two frame profiles 60 are thereby pushed onto the legs 80 of the angle piece 78, that the flanges 82 of the trapezoidal profile in each case engage in one of the two dovetail grooves 72. The limited by the dovetail grooves 72 middle part of the frame profile (again a dovetail profile) is held in this way in snug fit and with slight clamping in the profile of the elbow, the toothing of the flanges 82, einkrallt at the bottom of the dovetail grooves 72 and a retraction of the Frame frame prevents. In this way, with identical elbows 78 miter joints between the frame profiles can be made on both sides of the door. In this case, the flanges 82 of the angle piece also engage in that dovetail groove 72 which, according to FIG. 11 (in another longitudinal position), receives the clamping profile 68. It is understood that it may also be relatively short profile pieces in the clamping profiles 68, which only partially establish a connection between the frame profile and the clothing. In Fig. 11 it can also be seen that the limited by the dovetail grooves 72 middle part of the frame profile 60 is slightly behind the inner surface of this frame profile, namely just the thickness of the relevant wall portion of the elbow 78. This ensures that the frame profile 60 in its outer Edge area (left in Fig. 11) sat against the masonry 50.

In the following, a method will be described with which the door system presented here can be mounted in a door opening in a particularly efficient and secure manner. Fig. 14 shows the upper portion of a door opening 84 and the two vertical legs 14, 16 and a horizontal leg 86 of the door frame. The horizontal leg 86 is connected in a known manner, for example by means of known corner connectors, rigid miter with the vertical legs 14, 16. The thus formed The frame is set in the door opening 84 such that the vertical legs 14, 16 are supported by their lower ends on the floor and have some air to the lateral boundaries of the masonry. Accordingly, the horizontal leg 86 has some air to the upper boundary of the door opening.

5

The horizontal leg 86 of the door block is penetrated at two points, preferably in the region of its opposite ends of two clamping fittings 88. A single clamping fitting 88 is shown in perspective in FIG. It has a threaded bolt 90 and a support plate 92 which is rotatably supported at the upper end of the threaded bolt. The corners of the support plate 92 are bent into claws 94, with which the support plate can dig into the lintel or masonry, which limits the door opening 84 upwards. The threaded bolt 90 has a tool handle 96 at the lower end and is screwed from above into a corresponding threaded bore of the horizontal leg 86 such that the tool handle 96 of FIG. 15 is accessible from the underside of the leg 86. In the position shown in Fig. 14 then the threaded bolt with the aid of a tool is unscrewed so far that the support plate 92 is firmly supported under the edge of the door opening. In this way, the door frame, which rests with the lower ends of the legs 14, 16 on the floor, securely clamped in the door opening.

20

FIG. 14 also shows the flanges 56 of some of the staples 52 described with reference to FIG. 11, which serve to secure the lining. In the example shown, the flanges 56 are serrated on the edge bounding the slot for the webs 62,66.

OK

Before the lining 48 is fastened to the clips 52 in the manner shown in FIG. 11, a swelling foam 98, for example a PU foam, is applied to the inner surface of the door opening. Subsequently, the chuck 48 is attached and the door leaf 10 is hung in the hinges 24 of the door frame, which with the help of Spannbeschläge 88 is fixed. Preferably, the edges of the door leaf 10 are covered with spacer strips that completely fill the space between the door leaf and the legs of the door frame with the door closed, so that the door can be closed only with a slight resistance. Then, when the door is closed, these spacer strips serve as spacers, and the door frame formed by the legs 14, 16 and 86 is stiffened by the door leaf 10, while the swelling foam 98 swells. Due to the hardening expanding foam, the door frame, including the door frame, is then securely held on the masonry. After opening the door, the glued-on spacer strips are removed, so that the door has air on all sides in the folds of the door frame.
