EP3695080B1 - Rotary fitting for concealed arrangement on windows or doors - Google Patents

Description

The invention relates to a swivel fitting for windows or doors according to the preamble of claim 1.

Concealed rotary fittings are built into the frame on the one hand and in the profile of the adjoining door or window sash on the other hand in such a way that they allow doors or windows to be opened and closed without the individual parts of the rotary impact on the corresponding outer or visible surface of the The door or window. In addition, increased protection against break-ins is guaranteed by such rotary fittings, since the rotary fitting or the hinge is not accessible when the window or door is closed.

Furthermore, the swivel fittings, especially when an adjustment option is to be provided, are generally designed to be complicated in structure and are therefore expensive to manufacture and, moreover, difficult to operate.

From the DE 41 37 050 A1 a rotary fitting for a door is known in which both the frame and the door frame connected to the frame by the hinge elements are designed as a box profile. The known swivel fitting has a hook-shaped hinge bracket, the foot of which is fastened to the door frame profile to be pivoted by means of a separate holding part to be positioned inside the profile. A pin is provided on the holding part required for screwing the hinge bracket foot, which must be inserted from the interior of the door frame profile through the profile wall and inserted into a corresponding hole in the hinge bracket base in order to be able to attach the holding part. The other end of the hinge bracket ends in a holder in which the relevant end of the hinge bracket is pivotably mounted by means of a bearing pin. The holder is arranged within the frame profile so that the axis of rotation of the hinge bracket extends within the frame profile and essentially parallel to the axis of the frame profile. The installation and fastening of the bracket with the bearing pin for the hinge bracket takes place from the side of the frame profile which faces away from the door frame when the door is closed.

The ones from the DE 41 37 050 A1 known solution has the disadvantage that there is no possibility of adjustment in the construction of the rotary fitting elements, by means of which an adjustment of the door frame, and thus of the door leaf, can be carried out after installation in the frame. Such an adjustment is necessary in spite of the high accuracy in the manufacture of the individual parts of the door, especially in the case of large doors with relatively heavy door leaves, in order to enable the door leaf to be precisely fitted into the three-sided frame profile.

Is known from the DE 299 04 129 U1 a concealed rotary fitting for connecting a frame of the wing of a door or window made from a box or solid profile with the associated frame made from a box or solid profile. With a hook-shaped hinge bracket and a bracket arranged within the cross-sectional profile of the frame or the wing, which has a bearing pin that fixes one end of the hinge bracket within the bracket in such a way that the axis of rotation of the hinge bracket extends within the profile and parallel to its longitudinal axis. For the end of the hinge bracket remote from the axis of rotation, fastening means are provided, by means of which the hinge bracket is held adjustable relative to the frame or the door or window sash relative to the hinge bracket.

The disadvantage of this adjusting means is that, in order to adjust the wing, the adjusting means has to be released and tightened again after the adjustment. It is true that this rotary fitting can be adjusted by means of actuation, but the manufacture, assembly and also the operation for adjustment prove to be complex and expensive.

Furthermore, from the EP 1 617 025 A2 a hinge for butt closing doors emerges, in which two hinge parts can be rotated about a common hinge axis. At least one hinge part has a flap which can be pushed into a belt pocket in a door frame and which can be pivoted in the belt pocket about an axis running parallel to the hinge axis and adjustable in its set pivot pitch and in its height position. The rag engages pocket-like bearing element and is supported with its upper and lower ends guided on the upper and lower inner boundary surfaces of the bearing element. In addition, a transverse adjustment arrangement which effects adjustment of the lobe transversely to the hinge axis is provided between the tab and the bearing element, and a height adjustment arrangement which effects a height adjustment of the same is assigned to the bearing element. An end region of the tab engaging in the bearing element is operatively connected via a bearing part running parallel to the hinge axis with surfaces of arcuate cross-section with two mutually parallel boundary surfaces of the bearing element, the tab having an adjusting screw for pivoting and fixing the same within the bearing element.

In order to be able to meet the criteria for the use of rotary fittings with an adjustment device with large and high sash weights, a stable and compact structural unit of the hinge is required.

The invention is therefore based on the object of developing a rotary fitting for a window or a door of the type mentioned at the beginning, which is simple and inexpensive to manufacture, that a simple and exact installation of the rotary fitting is possible with subsequent exact adjustment relative to the frame, and specify a rotary fitting with adjusting means, which avoids the aforementioned disadvantages of the prior art.

The object is achieved with the means of the characterizing part of claim 1 in that a hinge bracket comprises an integrally formed thickening at its end remote from the axis of rotation, which is adapted to the walls of a hinge part that form the receptacle and faces the end of a receptacle, with one to for the thickening of the web-like section of the hinge bracket is spaced from the walls, and wherein the hinge bracket has an adjusting device with which the hinge bracket is held in the receptacle about its axis of rotation on the frame via the thickening on the wing. The advantages of the invention are, in particular, that when the rotary fitting according to the invention is used, the door or window sash held in a frame, the possibility of adjustment provided on the rotary fitting to the exact Fitting the pivotable wing can be made much easier and can be adjusted exactly even with prolonged use. For this purpose, adjusting means are provided between the end of the hinge bracket near the axis of rotation and the end of the hinge bracket remote from the axis of rotation, by means of which the wing profile and thus the door wing are held adjustable relative to the frame.

All adjusting means, consisting of the adjustment device and the adjustable section of the hinge bracket, are effectively related to the hinge part and together ensure that the elastic seals or sealing lips often present between the profile of the sash and the profile of the window frame have their intended effect, namely the seal the remaining column with the sash closed, can meet particularly effectively.

Advantageously, the adjustment via the adjustment device is essentially assigned to the hinge bracket and the hinge part attached to the sash. The swivel fitting with the swivel joint as a hinge bracket can be designed in a very simple construction and can be aligned in a simple, stable and inexpensive manner in a direction to adjust the pressure of the window or the door or the sash to the frame.

To realize an adjustment, in particular pressure adjustment of the window or the door, the sash can be displaced almost perpendicularly to the frame wall of the frame by means of the adjustment device.
Since, as a rule, at least two rotary fittings are required to attach to a frame and to a door or window sash, an undesired inclination of the sash can also be corrected by the adjustment device, the adjusting means of the two rotary fittings being adjusted differently.

A special hold, higher force absorption and a guide suitable for the purpose for the adjustability of the sash to the frame via the adjustment device is achieved in that the hinge bracket enters into a material connection with the thickening at its free end and the thickening perpendicular to the axis of rotation has a bolt-shaped shape occupies. The design also proves to be inexpensive to manufacture.

A simple constructive measure provides that the slot-like receptacle contains a cavity that is continuously enlarged in the width of the walls for receiving the thickening, the receptacle and the thickening forming sliding fits. Thus, for assembly, the thickening, which is located on the side of the hinge bracket remote from the axis of rotation, can be easily inserted from the open side of a cavity in the hinge part and, when the rotary fitting is adjusted by the adjusting device, the section can be limited to the walls.

The adjustment device and the hinge bracket together form a one-piece component as a preassembled unit, with the adjustment device being able to be mounted in the hinge parts received in a recess of the hinge bracket. According to the invention, the adjusting device consists of a bearing part fastened in a non-positive manner to the hinge bracket, an adjusting cam and a threaded pin. For the sake of simplicity, the hinge bracket with the bearing part is attached to each other by means of a rivet connection, whereby in the assembled state a recess that functions as a guide is formed for the adjusting cam, which protrudes with its free end forming collar from the rotatable bearing forming for the threaded pin.

According to the invention, the adjusting cam engages with a curvature arranged at the free end and the hinge bracket in the receptacle of the hinge part on the wing, the curvature favoring the receptacle forming a sliding fit. With almost the same dimensional adjustment of the curvature for receiving, as well as the thickening of the hinge bracket for receiving in the hinge part, in adaptation to the seat of the rotary fitting in the window or door, disruptive, non-functionally controlled movements are advantageously avoided.

According to a preferred embodiment, which proves to be space-saving, the threaded pin in the recess forming the hinge bracket and bearing part is guided cooperatively by means of a screw drive to adjust the adjustment device. For adjustment, the threaded pin has a tool engagement, preferably a hexagon socket for an Allen key, which is accessible from a hole in the hinge bracket. The pivot fitting can be adjusted in the pivot-open position of the sash relative to the frame due to the freely accessible position of the adjustment device.

So that a simple adjustment movement can be carried out, it is proposed that with freely accessible adjustment of the threaded pin outside the frame and sash, the adjusting cam moves perpendicular or almost perpendicular to the frame wall, the hinge bracket rotating around its axis of rotation on the frame and with the circular contour of the The thickening on the casement leaning against the mount is twisted.

In order to obtain a defined limitation for the adjustability of the pressure from the sash to the frame with means that are simple to manufacture and inexpensive, the receptacle and the section of the hinge bracket that is formed between the thickening of the hinge bracket and the curvature of the adjusting cam with the section in contact with the walls, limits the adjustment range of the swivel joint.

In order to achieve a simple construction and an inexpensive design of the rotary fitting in terms of manufacturing technology, at least parts are made from a die-cast material produced by the die-casting process or from a plastic material formed by the injection molding process.

Based on Figures 1 to 7 the arrangement of a swivel fitting 1 with two hinge parts 3 and 5 that are operatively connected to one another about a common axis of rotation 11 by means of a swivel joint 7 or hinge bracket 8 is explained. In these representations, profiles for the window or door 2 of the window frame 4 and wing 6 are designed as hollow metal profiles. However, the invention can also be used with plastic hollow profiles or with wooden profiles or with profiles made of material combinations. The following description is based on a rotary fitting 1, which can be used for windows, doors 2 or, in the same way, for large doors and possibly also in furniture construction.

the Figs. 1 to 2 show the rotary fitting 1 in the installed state of the window or door 2, seen from above. Fig. 1 shows a plan view in the closed position of the door or window sash 6 to the frame 4 in a sectional view. Fig. 2 shows the corresponding top view in the closed position of the door or window sash 6 to the frame 4 in a complete representation of the rotary fitting 1 outside the object.

The rotary fitting for the concealed arrangement on doors or windows 2 according to the Figs. 1 to 4 , thus has a first hinge part 3 for attachment to a wing 6 and a second hinge part 5 for attachment to a frame 4, a hinge bracket 8 being arranged to form a hinge-like pivotable connection of the swivel joint 7. To Fig. 1 if the hinge bracket 8 in the frame 4 has at one end 9 with the hinge part 5 fastened to the frame 4 for a bearing bolt 10 extending through a receiving bore 12, 13 forming an axis of rotation 11. With its facing the wing 6 other end 14 engages The hinge bracket 8 is operatively connected in a receptacle 15 of the hinge part 3 fastened to the wing 6, which is bordered with a rectangular cross-section.

After the Figures 1 and 3 to 7 the hinge bracket 8 comprises, at its end 14 remote from the axis of rotation 11, an integrally formed thickening 16, which follows the walls 17, 18 of the hinge part 3 that form the receptacle 15 Fig. 1 is adapted and facing the engaging end 19 of the receptacle 15. The hinge bracket 8 is up to the thickening 16 Fig. 1 formed as a web-like section 20 in the area of the walls 17, 18. The distance between the walls 17, 18 and the section 20 results from the remaining gap, which results from the difference between the diameter of the thickening 16 and the thickness of the section 20. Furthermore, on the hinge bracket 8 according to the Figures 1 and 3 to 7 an adjusting device 21 is provided, with which the hinge bracket 8 in the receptacle 15 after Fig. 1 is held rotatable about the axis of rotation 11 via the thickening 16.

To Fig. 1 Part of the adjustment device 21 with the section 20 of the hinge bracket 8 dips into the receptacle 15 of the hinge part 3. The door or window sash 6 held in a frame 4 can thus be precisely adjusted by the rotary fitting 1 within the receptacle 15 of the hinge part. In addition, the pivotable wing 6 is precisely fitted. For this purpose, between the end 9 of the hinge bracket 8 close to the axis of rotation and the end 14 of the hinge bracket 8 remote from the axis of rotation Fig. 1 Adjusting means are provided, by means of which the wing profile and thus the door wing 6 are kept adjustable relative to the frame 4.

All actuators after Fig. 1 , consisting of the adjusting device 21 and the adjustable section 20 of the hinge bracket 8 are in effective connection with the hinge part 3 and together cause the elastic seals or sealing lips that are often present between the profile of the wing 6 and the profile of the window frame 4 to follow Fig. 1 and Fig. 2 can fulfill their intended effect, namely the sealing of the remaining gaps when the wing 6 is closed, particularly effectively.

The adjustability of the sash 6 to the frame 4 is thus effected via the adjustment device 21 in an operative connection between the hinge bracket 8 and the am Blind frame 4 attached band part 3 after Fig. 1 . The swivel fitting 1 with the swivel joint 7 as a hinge bracket 8 can be designed in a very simple design and can be aligned in a simple, stable and inexpensive manner in a direction for adjusting the pressure of the window or door 2 or the sash 6 to the frame 4. After the Figures 3 to 5 three adjustment settings of the swivel joint 7 are shown, with the after Fig. 5 The setting shown is a first end position for the adjustability of the rotary fitting 1 in the assembled state Fig. 1 is equivalent to. As in Fig. 1 clearly visible, the section 20 of the hinge bracket 8 in the receptacle 15 rests against the wall 17, the hinge bracket 8 rotates with the section 20 in the receptacle 15 to the walls 17, 18 at an angle about an axis of rotation 22 of the thickening 16 is positioned. Fig. 3 has a second end position for the adjustability of the sash 6 relative to the frame 4. Not shown, but in a descriptive manner, the section 20 of the hinge bracket 8 in the receptacle 15 rests against the wall 18 rotated at an angle about the axis of rotation 22 of the thickening 16. the Fig. 4 represents the middle position of the adjustment device, after which an adjustment is possible in both directions. The section 20 of the hinge bracket 8 is not shown here in a position that is parallel and at the same distance from the walls 17, 18 without contact.
