Description

Hinge for doors that close butt

The invention relates to a hinge for doors that close butt, in which two hinge parts are rotatable about a common hinge shaft, so that at least one part of the hinge has a flap that can be inserted into a hinge bag in a door fence and that is pivotable in the hinge bag around an axis that extends parallel to the hinge axis and can be adjusted in its regulated articulation position as well as in its height position, in which the flap fits into a bearing element of the bag type and is supported with its upper closure and its lower closure on the upper and lower inner limiting surfaces of the bearing element, in which an end zone of the flap that fits in the bearing element and two limiting surfaces parallel to each other of the bearing element are in operative connection with each other on a bearing part formed in the end zone of the flap and which extends parallel to the axis of the hinge with arc-shaped surfaces in the cross-section, and in which the flap has a regulation screw for the articulation and fixation thereof within the bearing element.

Hinges with hinge parts adjustable in various directions are known in some embodiments. In the embodiment according to WO 02/086263 A1 on a hinge for doors that close butt, two hinge pieces are rotatable about a common hinge shaft. At least one hinge piece has a flap that can be inserted into a hinge bag in a door frame, which is rotatable in the hinge bag around an axis that extends parallel to the hinge axis and that is adjustable in its regulated articulation position as well as its height position. The flap is fixedly connected, but detachably with a pivotable flange around the axis that extends parallel to the axis of the hinge. In the flange fits a regulation screw for the articulation and fixation of the same and, in addition, to the flange is associated a regulation organ that causes a regulation of the height of the same. The flange can be inserted together with bearing blocks that are connected below and above it in common from the front side of a door fence in the hinge bag and can be screwed through a cover element and the bearing blocks with the bottom of the hinge bag. There are no relatively small mutual support surfaces in this case between the flap and the axial bolt that supports it. In addition, a complete pre-assembly of the hinge piece provided with the hinge bag is not previously necessary.

Another hinge for doors that close butt is known from DE 44 31 799 C1. Also in this known hinge, an axial bolt carries the flap. In addition, the flap can be supported on the upper and lower inner limiting surfaces, so that a fixing support is achieved without the danger of a lateral inclination. The flap and the bearing element are adjustable in height in common in the hinge bag. This results in simple possibilities for height adjustment, on the one hand, and the guided fixing support of the bearing element in the vertical direction, on the other hand. In this known hinge there is a need for a further improvement of the adjustment and fixing possibilities, in particular for the flap.

A hinge of the type mentioned at the beginning is known from document FR 2 411 292 A1. In this known hinge, a transverse regulation of the flap with respect to the bearing element and a regulation of the height of the bearing element are not provided.

A similar hinge is known from US 2004/128794 A1, in which a height adjustment arrangement is provided for regulating the height of the bearing element. The flap is adjustable at the angle relative to the bearing element.

From US 5 339 493 it is known from another similar hinge, in which the flap is adjustable against the bearing element both in height and in angle.

The invention has set forth the task of further improving in a hinge of the type mentioned above the possibilities of adjustment and fixation.

According to the invention, this is achieved because alternatively to the bearing part with arc-shaped surfaces in the cross section, the end zone of the flap and the two limiting surfaces are in operative connection with each other by means of support ribs with arc-shaped closure, which are formed on the limiting surfaces facing the essentially flat flap, because a cross-regulation arrangement is provided between the flap and the bearing element, which causes a flap adjustment transversely to the axis of the hinge as well as to the bearing element, a height adjustment arrangement is associated which causes a height adjustment thereof, because the bearing element is formed by a base piece and a cover element, the base piece presenting one of the limiting surfaces for the support of the bearing part and the two limiting surfaces upper and lower position for the support of the upper and lower closure (of the flap and in which the second limiting surface is formed for the support of the bearing part from the inner side of the cover element, because the base part is provided above and below the space configured for the housing of the flap with grooves aligned parallel to the axis of the hinge, being provided with hinge bushings that are arranged in the hinge bag, which pass through the grooves for driving the hinge base piece in a direction parallel to the hinge axis, and because as a height adjustment arrangement for the base piece and, therefore, also for the flap there are provided bolts of the base piece, which can be supported in the hinge bag, which can be adjusted in height by means of another adjustment screw, the base part of the bearing element being movable during adjustment ón of the height along the caps.

Through these measures according to the invention, essentially improved support and a simpler regulation possibility have been created. In particular, the articulation of the flap in the bearing element is essentially simplified through the alternative according to the invention. The same optimal possibilities are achieved in this way, of course, also for adjustment transversely to the hinge axis. If the flap is now more or less widely fitted in the bearing element, an optimal fixation is always achieved in the area of the bearing position in the bearing element.

In the alternative according to the invention to the bearing part with arc-shaped surfaces in the cross-section, the bearing part is formed by support ribs, configured on the two limiting surfaces opposite each other of the bearing element with arc-shaped closure, between which the flap is configured essentially flat. This is properly an equivalent embodiment, in which, however, the manufacturing of the bearing element and the cover element must be carried out in each case in another way.

Since, according to the invention, the bearing element is formed by a base piece and a cover element, where the base part has one of the delimiting surfaces for supporting the bearing part and the two bearing surfaces. upper and lower limitation for the support of the upper and lower closure of the flap and where the second limiting surface for the support of the bearing part is formed by the inner side of the cover element, the cover element is a separate part of the Bearing element and assembly and disassembly, but also the manufacture of the parts are simple and, therefore, also economical.

In order to achieve a good retention and a conduction of the bearing element in the vertical direction, the bearing element is provided according to the invention above and below the space configured for the housing of the flap with grooves aligned parallel away from the hinge, so that bushings are provided in the hinge bag for driving the bearing element in a direction parallel to the hinge shaft. In this way, stable driving can be carried out without problems of a lateral inclination and also the height adjustment has been carried out in this way easily.

For the realization of a height adjustment, according to the invention, the entire unit formed by the base piece and the bearing element and the flap can be moved in height in front of the hinge flange and the cover element . To this end, as a provision for height adjustment for the bearing element and, therefore, the flap is also provided with bolts that can be supported on the hinge bag, which can be adjusted in height by means of a regulation screw, so that the base part of the bearing element is movable along the bushings during height adjustment. In addition, it is proposed that the bearing element together with the mounted flap be inserted or can be inserted from the front side of the door frame into the hinge bag and be screwed or screwed with the bottom of the hinge bag. Therefore, the assembly and also a necessary disassembly are very easily carried out.

In addition, it is proposed that the bushings be equipped with an internal thread, so that the fixing of the bearing element is carried out in the hinge bag by means of screws that fit through the cover element in the bushings. Therefore, a multiple function can be associated with the bushings. They not only form the support and the conduction of the bearing element, but also its fixation in the hinge bag with the help of the cover element.

An embodiment of the hinge provides that the bearing part is formed by ribs that move towards both sides from the end zone of the flap that fits in the bearing element, which in each case have one of the shaped surfaces arc in the cross section. The free end of the flap is therefore supported on the two flat limiting surfaces opposite each other with the arc-shaped surfaces and, therefore, in this embodiment it can act in the same manner as a post of bearing with an axial bolt.

A variant provides in this context that the two arc-shaped surfaces are, in general, partial sections of a single circular arc. In this way, it is ensured that the arc-shaped surfaces are always supported and, therefore, in each articulation position, on the flat limiting surfaces.

Therefore, it is also possible that the entire bearing part is configured as a cylindrical thickening of the free end of the flap. However, then this may condition a little more material expense, but the simplest manufacturing is configured.

In addition, it is proposed that a threaded rod inserted in a hole in the flap, which fits into a rotating threaded nut, but not detachably retained in the direction of the bearing element in front of the hinge axis is provided. the bearing element. In this way, this regulation is also possible with simple technical means and, above all, a simple adjustment is also possible after the assembly of the hinge. In addition, there is a self-inhibiting regulation, which does not release automatically.

A simple constructive configuration foresees in this context that the threaded nut has radial holes in its outer boundary for the support of a regulating tool.

In addition, it is proposed that the adjustment screw for the articulation and fixing of the flap in the bearing element crosses the flap and rests with its ends on the limiting surfaces opposite each other of the bearing element. This regulation can also be carried out easily after the hinge is assembled, the desired simple construction being guaranteed and, above all, the necessary self-inhibition.

In connection with the regulation in the most different directions, it is especially advantageous that both the threaded nut and the adjustment screw are freely accessible through holes in the cover element.

Examples of embodiment of the invention are explained in detail in the following description with the help of the drawing. In this case:

Figure 1 shows a horizontal section through a fence and a door with a hinge inserted in a hinge bag.

Figure 2 shows a section according to line II-II in Figure 3.

Figure 3 shows a section according to line III-III in Figure 1.

Figure 4 shows an inclined view of a hinge piece with an embodiment of the flap.

Figure 5 shows a partial view of another embodiment of a bearing part between a bearing element and the flap.

In a hinge 1 for doors 9 that are closed butt, two hinge pieces 2 and 3 are provided, which are rotatable about a common hinge shaft 4. At least one hinge piece 3 has a flap 7, which can be inserted in a hinge bag 5 in a door fence 6, so that this flap 7 is pivotable in the hinge bag 5 around an axis that extends parallel to the hinge axis 4 and can be adjusted in its adjusted articulation position as well as in its height position. The flap 7 fits into a bearing element 8 of the bag type. The end zone of the flap 7, which fits into the bearing element 8, is in operative connection with two limiting surfaces 13, 14 arranged parallel to each other of the bearing element 8 through a bearing piece 10, which extends parallel to the axis of the hinge 4, with surfaces 11, 12 essentially arc-shaped in the cross section. The flap 7 is supported guided with its upper and lower closure 15, 16 on the upper and lower inner limiting surfaces 17, 18 of the bearing element 8. The flap 7 has a regulation screw 19 for articulation and fixing thereof within the bearing element 8. Between the flap 7 and the bearing element 8, a transverse regulation arrangement is also provided, which causes a regulation of the flap 7 transversely to the axis of the hinge 4 - which is explained further below. -. To the bearing element 8 is associated a height adjustment arrangement that causes a height adjustment thereof.

The bearing element together with the mounted flap 7 is inserted or can be inserted from the front side of the door frame 6 into the hinge bag and is screwed or it can be screwed with the bottom 20 of the hinge bag 5. In this case, the bearing element 8 is formed by a base piece 21 and a cover element 22. The base piece 21 has one of the limiting surfaces 13 for supporting the bearing part 10 and the two surfaces of upper and lower limitation 17,18 for the support of the upper and lower closure 15, 16 of the flap 7 and in addition, the second limiting surface 14 for the support of the bearing part 10 is formed by the inner side of the element of cover 22.

The base piece 21 is provided above and below the space configured for the housing of the flap 7 with grooves 23, 24 aligned parallel to the axis of the hinge 4, so that bushings 25 provided in the hinge bag are provided. 5 for driving the base piece 21 in a direction parallel to the hinge shaft 4. The bushings 25 are configured with an inner thread, so that the fixing of the base piece of the bearing element 8 in the hinge bag 5 it is carried out by means of screws 26 that fit through the cover element 22 in the bushes 25.

In the example shown in accordance with Figures 1 to 4, the bearing part 10 is formed by ribs that distance both sides at the free end from the flap 7, which have an arc-shaped surface 11, 12 in the cross section. The two arc-shaped surfaces 11, 12 are preferably, in general, partial sections of a single circular arc. The entire bearing part 10 can be configured, if necessary, also as a cylindrical thickening of the free end of the flap 7.

In a variant, shown in Figure 5, the bearing part is formed by support ribs 27, 28 with an arc-shaped closure, which are configured on the two limiting surfaces 13, 14 opposite each other of the element of bearing 8, between whose support ribs the flap 7 configured essentially flat is inserted.

As a transverse regulation arrangement for the regulation of the flap 7 in front of the bearing element 8 transversely to the axis of the hinge 4, a threaded bar 31 is provided inserted in a hole 30 in the flap 7, whose threaded bar fits into a threaded nut 32 swiveling, but not detachably retained in the base piece 21 of the bearing element 8. In order to be able to make an adjustment from the outside when the hinge is mounted, the threaded nut 32 has radial holes 33 in its outer limitation for the application of A regulation tool.

For the articulation and fixing of the flap 7 in the bearing element 8, a regulating screw 19 is used, which passes through one of the flaps 7 in a threaded bore 29, which has, for example, an internal attack element 34 for the application of a tool. The ends of the adjusting screw 19 are supported on the limiting surfaces 13, 14 opposite each other of the bearing element 8.

Both the threaded nut 32 and also the adjustment screw 19 are freely accessible through holes 35, 36 in the cover element 22.

As a height adjustment arrangement for the base piece 21 and, therefore, also for the flap 7, bolts 37 are provided that can be supported on the hinge bag 5, which are adjustable in height by means of a regulating screw 38. The base element 21 of the bearing element 5 is movable during height adjustment along the bushings 25. To have here a possibility of bilateral use of the hinge and also for the purpose of blocking in an adjusted position, such support bolts 37 with regulating screws 38 may be present on the upper side and also on the lower side of the bearing element. A simple construction is deduced from the drawing. Support pieces 40 are provided that can be inserted laterally into recesses 39 of the base piece 21 of the bearing element 8, which in each case receive a bolt 37 and a regulation screw 38. The recesses 39 and also the parts of support 40 are made approximately elliptical, so that they are retained in their position through insertion and spin-proof.

All the parts of the hinge 1 and also of the bearing element 8 are generally made of metal. But it is also conceivable that at least partial sections are made of plastic. In the invention, it is especially advantageous that all the adjustable elements of the hinge 1 and the bearing element 8 are not accessible when the door is closed. Only when the door is hinged to the open position, can the hinge be adjusted three-dimensionally. In this way there is an optimal adjustment position also in doors that close butt.
