DOOR PLACEMENT

Description

Main application:

[0001] The invention relates to a door assembly according to the preamble of claim 1, comprising a door frame, a door leaf, and at least one hinge with a frame part and a leaf part. The invention relates in particular to a door assembly in which the hinge is at least partially concealed, wherein the frame part is designed to be inserted laterally into a reveal of the door frame.

[0002] Such a door hinge is known, for example, from DE 101 64 979 B4 and DE 20 2014 102 793 U1, wherein it is installed as a concealed door hinge in the narrow sides of the door leaf and the jamb side on the door frame and is not visible when the door is closed. The two hinge brackets are each rotatable at one end about a vertical axis of rotation and longitudinally displaceable and rotatable at the other end.

[0003] The door hinge is characterized by a stable construction and good performance. To allow for the formation of the necessary guides on both the door leaf and the frame, these components must be of sufficient size, and the door frame must also provide adequate space for the door leaf.

[0004] The present invention is based on the objective of providing a door arrangement that enables a compact design of the door hinge and has a high-quality appearance.

[0005] The problem is solved by a door arrangement comprising a door frame, a door leaf, and at least one hinge comprising a frame part and a leaf part, wherein the door frame, in the closed position of the door leaf and thus also in the closed position of the hinge, has a mirror section aligned parallel to the door leaf and a reveal perpendicular to it, adjoining the door leaf laterally, wherein the reveal, starting from the mirror section, has a first reveal section and a second reveal section adjoining it via a step, and wherein the frame part is inserted into an opening of the reveal, which extends from the first reveal section to the second reveal section, and a separate cover part with a step is arranged on the frame part.wherein a first cover section of the cover part is flush with the first reveal section and a second cover section is flush with the second reveal section.

[0006] The mirror section therefore extends along a first horizontal direction as well as the vertical direction, while the jamb section - except for the offset along the first horizontal direction at the step - extends perpendicular to the first horizontal direction along a second horizontal direction as well as the vertical direction.

[0007] The step acts as a stop for the door leaf.

[0008] Because the frame section is inserted into an opening in the reveal, it is partially concealed. In particular, since the opening extends from the first reveal section to the second, the step area can also be used for positioning the frame section.

[0009] To ensure a high-quality appearance visible from the outside, a separate cover part is arranged on the frame part, which has a step corresponding to the reveal, so that a first cover section of the cover part connects at least substantially flush with the first reveal section and a second cover section connects at least substantially flush with the second reveal section.

[0010] In the simplest case, the cover plate is designed in its shape and, primarily, in its height, such that after the cover plate is attached, both the first cover section and the second cover section are flush with the first reveal section. Attachment is achieved, for example, via a screw, adhesive, or clamp connection.

[0011] A cover plate designed in this way has the advantage that its one-piece construction allows for simple attachment to the frame. However, a differently designed cover plate must be provided for each type of frame, and minor differences in manufacturing tolerances cannot be compensated for.

[0012] Against this background, the cover part is preferably designed to be adjustable along the first horizontal direction. According to a further development, the cover part therefore has one or more adjustment means in the first cover section, which are received in a guide, in particular a dovetail guide, by means of which the distance between the first cover section and the frame part can be adjusted.

[0013] In this context, a dovetail guide represents a preferred embodiment of a guide. However, the invention also encompasses T-guides or other types of quasi-positive locking connections. A dovetail guide is based on a tongue-and-groove connection, wherein the groove has a conical cross-section into which a similarly conical spring is inserted and mounted to be longitudinally displaceable along the conical groove. In this case, the spring is an adjustment element, preferably a screw with a conical screw head, wherein the screw heads are mounted in the conical groove and engage in a corresponding threaded recess in the frame member.

[0014] A dovetail guide creates an almost form-fitting connection perpendicular to the dovetail, or perpendicular to the conical groove, so that when the screws are adjusted, their conical screw heads move the first cover part either in the direction of the frame part or in the opposite direction to it.

[0015] This type of adjustment allows the first cover section to be flush with the frame. However, with this design, the cover section remains a single piece, meaning the step between the first and second cover sections is predetermined and cannot be adjusted to different reveal heights.

[0016] Preferably, the cover part is designed in two parts, wherein the cover part has a base and a cover plate arranged on it, and the first cover section is formed on the base and the second cover section on the cover plate.

[0017] With such a design, several adjustment options are available between the base and the cover plate, so that the step or step height between the first and second cover section can be adjusted to the first and second reveal sections.

[0018] According to a first embodiment of such an adjustment mechanism, the base has a recess that engages in a groove for the cover plate. This recess forms a snap-fit ​​connection with the groove by means of a profile provided on each of its side surfaces, allowing the distance between the base and the cover plate to be adjusted. Suitable profiles include, for example, teeth, arcs, or the like. The depth and number of these profiles are selected to ensure that, on the one hand, the cover plate can be easily and, as far as possible, flush with the surface, and on the other hand, that the cover plate is securely fastened to the base. In addition to the design of the profile, the material used is also of particular importance. Preferably, both the base and the cover plate are made of a material that exhibits a certain degree of flexibility. This is preferably a plastic.Alternatively, the shape can also be assigned to the cover plate, in which case the base is provided with a corresponding base groove.

[0019] According to a second embodiment, the base and the cover plate each have a collar, the collars being designed such that a friction-fit connection is formed between them during assembly, allowing the distance between the base and the cover plate to be adjusted. The cover plate is adjusted and fastened to the base by means of an interference fit formed between the two collars.

[0020] Preferably, the step has a groove along its slope, and the cover plate has a recess flush with the groove into which a seal can be inserted. This allows the door assembly between the door frame and the door leaf to be sealed when closed.

[0021] According to a further development, the groove is divided into an upper section and a lower section by an intermediate space, with the sections separated from the intermediate space by a cover surface. Thus, the door assembly is divided into an upper and a lower sealing section, into each of which a seal can be inserted.

[0022] Previously, possible, preferred designs of the cover part were explained using examples. Accordingly, both adjustable and non-adjustable designs are possible.

[0023] With a non-adjustable cover plate, the installation depth of the frame section and the height of the step must be fixed if a flush fit is desired. If the only aim is to at least partially conceal the frame section and aesthetic requirements are less stringent, recessed steps between the reveal and the cover plate may be acceptable.

[0024] If the step height is fixed, but the installation depth of the frame section can vary, it is advisable to design the entire cover plate to be adjustable along the first horizontal direction. In addition to the adjustment method described using dovetail guides, washers or shims can also be used, for example. It is also possible, among other things, to design the cover plate so that it clamps within the opening of the reveal and is then inserted to the desired depth.

[0025] In both of the previously described variants, the cover plate can be manufactured in a single piece in a particularly simple manner, allowing it to be mounted in the specified position or adjusted along the first horizontal direction. Manufacturing using a plastic injection molding process is especially suitable, and the cover plate can optionally be adapted to the shape and structure of the frame or reveal.

[0026] If, on the other hand, the installation depth or the setback of the frame part relative to the first reveal section is fixed, but the height of the step can vary, the cover part is expediently designed to be at least two-part, with the first cover section being flush with the first reveal section and the second cover section being adjustable according to the step height so that it too is flush with the second reveal section.

[0027] Finally, a design is also possible in which both the first cover section and the second cover section are adjustable, whereby the measures described above can be combined with each other, for example.

[0028] The door arrangement according to the invention is particularly preferred when the door leaf is made of glass.

[0029] The invention will now be explained in more detail with reference to a drawing that illustrates only one embodiment. The drawing shows: Fig. 1 a door arrangement according to the invention, Fig. 2 a door arrangement according to the invention with a non-adjustable cover part, Fig. 3a a door assembly with a one-piece, adjustable cover plate, Fig. 3b the door arrangement of the Fig. 3a in a sectional view Fig. 4a a door assembly with a two-piece cover and snap-fit ​​connection, Fig. 4b the door arrangement of the fig. 4a in a sectional view Fig. 5a a door assembly with a two-piece cover and friction-fit connection, Fig. 5b the door arrangement of the Fig. 5a in a sectional view Fig. 6 a door arrangement with a separate groove.

[0030] The Fig. 1 Figure 1 shows a door assembly with a door frame 1, a door leaf 2, and at least one hinge 3 with a frame part 4 and a leaf part 5. In the closed position of the hinge 3, and thus also of the door leaf 2, the door frame 1 has a mirror section 6 aligned parallel to the door leaf 2 and a reveal 7 extending perpendicular to it and laterally adjoining the door leaf 2. The reveal 7 has a first reveal section 8 extending from the mirror section 6 and a second reveal section 10 adjoining it via a step 9. The frame part 4 is inserted into an opening 11 in the reveal 7, which extends from the first reveal section 8 into the second reveal section 10.

[0031] According to the Fig. 1 The mirror section is thus created along a first horizontal direction x and the vertical z, while the reveal 7 – except for step 9 – runs along a second direction y and the vertical z. Due to both the opening 11, into which the hinge 3 with the frame part 4 is inserted into the door frame 1, and the step 9 formed between the first reveal section 8 and the second reveal section 10, the viewer, especially when the door is open, experiences a less than optimal appearance from an aesthetic point of view. Therefore, this area is compensated for by a corresponding cover part 12, which can optionally be adapted to the reveal 7 in terms of its structure and color.

[0032] According to the Fig. 2 A separate cover part 12, featuring a step, is arranged on the frame section 4, such that a first cover section 13 of the cover part 12 is flush with the first reveal section 8 and a second cover section 14 is flush with the second reveal section 10. The cover part 12 is shaped to fit the opening 11, with the distance between the first cover section 13 and the second cover section 14 corresponding to the distance between the first reveal section 8 and the second reveal section 10. In the example shown, the cover part 12 is attached by means of an adhesive bond, although screw or clamp connections are also possible in principle.

[0033] The Fig. 3a and 3bFigure 1 shows a door assembly with a one-piece cover part 12, wherein the cover part 12 has, in the first cover section 13, an adjustment element in the form of a screw connection 16 in both an upper and a lower section of a dovetail guide 15, by means of which the distance between the first cover section 13 and the frame part 4 can be adjusted. By turning the screw connection 16, the cover part can be adjusted so that it lies flush against the first jamb section 8.

[0034] Due to the one-piece design of the cover part 12, the distance between the first cover section 13 and the second cover section 14 is predetermined, and the cover part 12 is selected according to the height of the step 9 or the distance between the first reveal section 8 and the second reveal section 10.

[0035] The Fig. 4a and 4bFigures 5a and 5b show a door arrangement with a two-part cover part 12, which has a base 17 and a cover plate 18, wherein the first cover section 13 is formed on the base 17 and the second cover section 14 is formed on the cover plate 18.

[0036] According to the Fig. 4a and 4b The base 17 has a projection 19 that engages in a cover plate groove 20, and the projection 19 forms a snap-fit ​​connection with the cover plate groove 20 by means of a profile 21 provided on each of its side surfaces, via which the distance between the base 17 and the cover plate 18 can be adjusted. In this case, the profile 21 is realized by teeth formed on each of the side surfaces of the cover plate groove 20 and the projection 19, although other types of profile 21 are also possible, e.g., in the form of arcs.

[0037] According to the Fig. 5a and 5bThe base 17 and the cover plate 18 each have a collar 22, 23, wherein the collars 22, 23 are designed such that a friction-fit connection is established between the collars 22, 23 during assembly. This allows the distance between the base 17 and the cover plate 18 to be adjusted, so that, similar to the one described in the Fig. 4 The mechanism shown allows for a flush fit of the first cover section 13 to the first reveal section 8 and of the second cover section 14 to the second reveal section 10.

[0038] From the Fig. 6A door arrangement is shown in which the step 9 has a groove 24 along the step slope and the cover part 12 has a receptacle 25 flush with the groove 24, wherein the groove is divided by a gap 26 into an upper section 27 and a lower section 28, and wherein the sections are each separated from the gap 26 by a cover surface 29, 30. A seal 31 is inserted into the groove 24, and into the upper section 27 and the lower section 28 of the groove 24, respectively, whereby in the example shown only the seal 31 in the lower area 28 of the groove 24 is visible.
