Description

The invention relates to a door hinge for a concealed arrangement between the door leaf and door frame. The door hinge comprises two receiving bodies, which can be used in recesses of the door frame and in the narrow side of the door leaf. In addition, the door hinge comprises an at least two-part joint, which connects the receiving body.

A concealed door hinge is, for example, in EP 1 308 592 A2 described. Door bands of this type have two elongated receiving body, which are rotatably connected to each other via a hinge bracket assembly. One of the receiving body is fastened in a recess of the door frame and the other receiving body in the narrow side of a door leaf. For ease of installation, it has been proven in practice to equip door hinges of this type with adjusting devices, whereby the door is adjustable relative to the door frame. The adjustability can be realized either in one or more independent directions.

In a door hinge, which is equipped with one or more adjusting devices, for example, inserts are provided, which are arranged in one or both receiving bodies. In terms of manufacturing, this means that a receiving body of a door hinge without adjusting devices differs structurally from a receiving body of a door hinge with adjusting devices. Likewise, the receiving body can also differ in terms of their dimensions. Thus claimed, for example, a receiving body to which a Schamierbügelanordnung is to be attached for the transmission of large loads, and moreover has a plurality of adjusting significantly more space within the frame or within the door leaf, as a receiving body, no adjustment and to which a less resilient Schamierbügelanordnung is attached.
Against this background, the invention has for its object to provide a door hinge, which is designed simpler and therefore is less expensive to manufacture.

The object is achieved in that the receiving body of the concealed door hinge at the end each comprise two head modules having openings for fastening screws and where the joint is mounted. According to the invention a separate intermediate piece is arranged between the head modules, which connects the two head modules. Each of the head modules in this case comprises a mounting surface with which the module is to be fastened in the recess. The modular design of the receiving body offers the advantage that, for example, two door hinges, which differ in terms of the height of their joints, can be equipped with the same head modules. There are only different levels of intermediate pieces ready to hold, which are adapted to the given height of the respective joint. It is therefore not necessary to construct a separate receiving body for each door hinge variant.

Conveniently, the intermediate piece, which connects the two head modules together, is formed substantially U-shaped. A U-shaped configuration is particularly preferred because the recesses into which the receiving body are inserted, for visual reasons to be completely or at least largely hidden. Alternatively, however, in principle also an intermediate piece may be provided, which is formed from two lateral plates or a simple back plate. The head modules can be fixed without restriction by screws, rivets or a plug connection to the intermediate piece. For example, in the preferred U-shaped configuration on the side surfaces and / or openings may be provided on the rear surface of the intermediate piece, engage in the projections of the head modules or other fastening means. Regardless of the design of the intermediate piece its function is to fasten the two head modules of a receiving body for the purpose of assembly within the recess of a frame or door leaf together. Since the head modules are firmly bolted with their mounting plates within the frame and within the wing, the intermediate piece is no supporting function.

In a preferred embodiment of the door hinge according to the invention, it may be provided that the head modules are formed from metal castings. In terms of production, castings are comparatively expensive, but since according to the invention only the head modules are to be manufactured as cast parts, there is a potential for cost savings in the production of door hinges of different types in large numbers. Due to the modular design of the receiving body of the door hinge, it is now no longer necessary to manufacture and keep holding body for different dimensions and required different shapes. It only requires a production and availability of different height intermediate pieces, which then in combination with the head modules receiving body of the desired type are to be formed. It may, for example, also be provided that the intermediate piece is formed from sheet metal. Sheet metal has the advantage that it is easy to process and therefore a further cost reduction can be achieved. Even with thin sheets sufficient strength of the entire door hinge receiving body can be achieved. This is due to the fact that the forces and moments that are transmitted from the door leaf to the door frame via the door hinge are transmitted essentially by the head modules fastened to the door frame and the door wing and the joint attached thereto. For this reason, the intermediate piece may for example also be formed from plastic.

Conveniently, the intermediate piece is fixed by clamping to the head modules of a receiving body. Preferably, the clamping connection may be formed by a grain or a comparable local material deformation. For this purpose, the head modules can, for example, have a depression in the form of a groove. The clamping connection has the advantage that it can be produced particularly easily in the manufacture of the door hinge, and that no further fastening elements are required. Alternatively or in addition to the clamping connection, a screw connection can be provided, with which the intermediate piece is screwed to the head modules of a receiving body. Due to the screw the modular composite receiving body receives a higher stability. In the assembly of receiving bodies with particular large dimensions, this stability may be desirable. As an alternative to the screw or to the clamp connection and other compounds, such. B. rivets or bent retaining lugs conceivable. Furthermore, material-locking connections may also be expedient. For example, the head modules with the intermediate piece can be fastened to one another by a welded connection.

With regard to a further reduction of the production costs, it may be useful for at least one of the receiving bodies to have two head modules of the same design. Especially in castings, where a corresponding casting mold must be present during production, it is advantageous if no different shapes are to be used for the two head modules of a receiving body. It therefore requires in the production of a receiving body only a small form for the production of the head modules. Two such identical head modules then form together with the intermediate piece the receiving body.
In a preferred embodiment of the door hinge according to the invention can be provided that the head modules each have an end-side extension for attachment in a recess. Preferably, it can be provided that the head modules each comprise a support element and an insert, wherein in the insert, the joint is mounted. Such a multi-part design of a head module allows the arrangement of adjusting means for adjusting the door used within the frame.

With regard to a vertical adjustment of the door leaf may, for example, be provided that in a head module adjusting means are provided for adjusting the door leaf in the vertical direction, wherein the vertical direction is determined by the longitudinal direction of the receiving body. This adjustment can, for example, be realized in that the carrier element of the head module is displaceable relative to the extension piece. Such displaceability can be achieved in that the extension piece has vertically aligned slots, which are penetrated by screws which are arranged in the carrier element. If the extension piece, for example, already fixed within the recess of a frame, so can be moved relative to the extension piece in the vertical direction by loosening the screws which pass through the slots, wherein on the support the hinge of the door hinge and thus the door leaf is attached. Alternatively or in addition thereto, provision may also be made for an adjusting screw acting on a wedge to be arranged in the head module, the wedge being oriented at right angles to the adjusting screw and in the vertical direction. In this case, the wedge on the support of the head module is such that by actuation of the adjusting screw of the carrier can be positioned in the vertical direction.

In a further embodiment of the door hinge according to the invention can also be provided that in a head module adjusting means for adjusting the door leaf in a first horizontal direction (X) are provided. This first horizontal direction (X) is orthogonal to the front side of the associated receiving body. With such an adjustment can the Side folding air of the door leaf can be adjusted within the door frame after inserting the door. Can be realized, the adjustment of the door leaf in the first horizontal direction, for example. By a spindle with which the insert is mounted in a carrier. By adjusting the spindle, the insert is adjusted relative to the carrier in the first horizontal direction (X), whereby the lateral position of the door leaf, which is connected via the joint with the insert in the carrier, is variable.

A further embodiment of the door hinge according to the invention provides that in a head module adjusting means for adjusting the door leaf in a second horizontal direction (Y) are provided. This second horizontal direction (Y) runs parallel to the front surface of the associated receiving body. Such an adjustment means can, for example, be realized in that the use of a head module has horizontally aligned elongated holes, which are penetrated by at least one screw which can be fastened in the carrier of the head module. Alternatively, an eccentric can be provided, which causes a shift between the insert and the carrier. By actuating this eccentric, the insert is then adjusted relative to the carrier in the second horizontal direction. By adjusting the door leaf in the second horizontal direction (Y), the pressure position of the door leaf can be adjusted within the frame.

In a particularly preferred embodiment of the door hinge according to the invention, it is expedient that in the head modules of a receiving body adjusting means for adjusting the door leaf in the vertical direction (Z) are arranged. At the same time adjusting means for adjusting the door leaf in a first horizontal direction (X) and / or adjusting means for adjusting the door leaf in a second horizontal direction (Y) are arranged in the head modules of the other receiving body. In this case, the vertical direction (Z) is determined by the longitudinal direction of the receiving body. The second Horizontal direction (Y) is orthogonal to the first horizontal direction (X). This embodiment of the door hinge makes it possible to adjust the door leaf in two or all three spatial directions relative to the door frame. The adjusting means can be designed as described above. By a common arrangement of both adjusting means for adjustment in one and in the other horizontal direction within a receiving body arise in the adjustment of the door after its insertion in the door frame benefits related to the operation of the adjustment. The arrangement of the adjusting means in a receiving body ensures that even with an opening angle of the inserted but not yet adjusted door of, for example, about 90 °, the two adjustment axes (X, Y) continue to extend mutually orthogonal. This would not be the case if the adjustment means for the first horizontal direction is arranged in the one receiving body and the adjusting means for the second horizontal direction in the other receiving body. The installer can thus adjust the arrangement of the adjustment means for the horizontal adjustment in a receiving body which a horizontal direction regardless of the other horizontal direction and thus adjust the door easier. Preferably, the fitter will use the door hinge so that the adjusting means are arranged in that receiving body, which is associated with the door leaf.

In a particularly preferred embodiment of the door hinge according to the invention can be provided that the hinge has two hinge brackets, which are rotatably connected to each other by a common axis of rotation. Each hinge bracket is rotatably mounted on one side in the inserts and slidably mounted on its other side in slide guides of the inserts. Alternatively, it can also be provided that one of the two hinge brackets is rotatably mounted on both sides and the other hinge bracket is slidably mounted on both sides in sliding guides of the inserts. It can also be provided that the joint has at least two multi-membered hinge bracket, which are scissor-like connected to each other and are mounted on at least two axes of rotation in the housing.

With regard to the optical design of the door hinge, it may be expedient that at least one cover can be fastened and released again on a head module, whereby openings for fastening screws can be covered. Such a cover may, for example, be color matched to the design of the door frame, whereby the concealed door hinge is disposed inconspicuously in the frame even when the door is open. If the door frame and the door leaf have a different color design, then it may be appropriate for the head modules, which are arranged in the door frame, to be provided with covers other than those head modules, which are arranged in the door leaf.
