Abstract

The arrangement involves a frame band part (32) fixed to the frame (10) and a panel or pane band part fixed to the panel or pane (20) located pivotably in relation to each other. The bands (30) with the panel or pane closed are arranged invisibly from the opening side in the interior of the fixed frame and the panel or pane. The panel or pane band part is pivotable round a hinge axis located in the interior of the fixed frame near its front wall (2). The frame band part has a cross-section vertical to the hinge axis fitting in a chamber (4) of the fixed frame. The frame band part is fixed by means of screws (46) to at least one (6) of the walls (6,7) of the chamber running vertically to the frame plane.

Description

The invention relates to a belt arrangement of the type corresponding to the preamble of claim 1.

Such hinge arrangements are well known. In the vast majority of cases, the hinges are attached to the visible side or opening side of the frame and sash facing the inside of the room. They therefore form protruding parts that protrude from the visible side of the fixed frame and the sash or sash frame and are attached using screws. The protruding hinge parts disrupt the calm appearance of the door, window and the like, represent a certain risk of injury and also represent a security risk insofar as they are openly accessible to attempted break-ins.

The invention is based on the object of creating a generic band arrangement that is not visually noticeable and does not pose any risk of injury or break-in.

This object is solved by the invention set out in claim 1.

Due to their arrangement inside the frame and the sash, the hinges are visible and easy to access when

closed wing withdrawn.

Claim 2 represents an important prerequisite for the other hinge part mounted on hinge parts in the fixed frame to be able to pivot through a sufficient opening angle.

The frame hinge part can correspond in its cross-section perpendicular to the hinge axis to the cross-section of the chamber formed in the fixed frame, i.e. essentially fill this chamber, so that a transmission of the forces introduced from the sash hinge part via the hinge pin into the frame hinge part is ensured over large cross-sections (claim 3).

If the hinge is a two-part hinge, the frame hinge part only has a hinge part arranged on one side of the sash hinge part. In the case of a three-part hinge hinge, hinge parts of the frame hinge part are provided on both sides of the sash hinge part.

For the arrangement of the screws for securing the frame hinge part, the arrangement shown in claim 4 is recommended, which makes it possible to carry out the fastening on walls of the fixed frame, which are not visible from the opening side of the sash and which are usually made of a hollow profile.

Claim 5 represents a possible design of the sash hinge part, which engages the sash or the hollow profile forming it with a leg that is not visible from the opening side.

Claim 6 is directed to an embodiment of the sash hinge part which allows it to be accommodated in the fixed frame and yet still allows it to be opened by a sufficiently large pivoting angle.

In the embodiment according to claim 7, the projection of the angle part of the hinge part in a plane perpendicular to the hinge axis is as small as possible. The hinge part moves with the cylindrical surface past the edge of the recess of the fixed frame.

It is advantageous if the angle part and the

Legs of the sash hinge part are separate parts which are connected to one another at separating surfaces parallel to the sash plane (claim 8) and if the connection is adjustable perpendicular to the hinge axis (claim 9), in particular by means of a toothing according to claim 10.

In this way, the sash can be adjusted in the frame opening parallel to the frame or sash plane using simple means.

It is not impossible that the leg of the sash hinge part engages in a chamber of the sash, in particular in a chamber of a hollow profile forming the sash frame. In the preferred embodiment according to claim 11, however, the leg rests from the outside on a wall of the sash in the rebate area and is fastened there (claim 11), whereby here too, cooperating teeth parallel to the hinge axis (claim 12) can be provided in order to be able to set the sash perpendicular to the frame or sash plane and to be able to adjust the cover dimension or the sealing pressure.

The screws for securing the leg can engage in a fastening piece according to claim 13, which according to claim 14 is provided with wedge-shaped inclined side surfaces which interact with correspondingly wedge-shaped counter surfaces on the wing.

The fastening piece and thus the fastening screws thus experience a forced and play-free positioning.

An embodiment of the invention is shown in the drawing.

Fig. 2 shows a horizontal section along the line H-II in Fig. 1;

Fig. 3 shows a front view of the belt;

Fig. 4 shows a view along the line IV-IV in Fig. 3;

Fig. 5 shows a view from above, partly in section, along the line V-V in Fig. 3.

Fig. 1 and 2 show the frame area of a door, a window or the like with a fixed frame 10 and a sash frame 20, which are connected to one another by a plurality of, generally two or three, hinges 30 distributed over the height so as to be pivotable about a hinge axis A which is vertical in the exemplary embodiment. In the exemplary embodiment, the hinges 30 are hinged hinges with a sash hinge part 32 and two hinge parts 31', 31' fastened to fixed frames 10 above and below, which are collectively referred to as frame hinge part 31.

In the exemplary embodiment, the fixed frame 10 comprises a frame profile 1 with a flat front wall 2, to the rear of which the band 30 is attached with its frame band part 31. On the side facing away from the band 30, a frame outer profile (not shown) is attached to the frame profile 1 via heat-insulating plastic webs 3. Accordingly, the casement frame 20 comprises a casement frame profile 11 with a flat front wall 12; on the rear of the casement frame profile 11, a casement frame outer profile 14 (not shown) is attached via heat-insulating plastic webs 13. All actual frame profiles consist of extruded aluminum hollow profiles.

The design of the fixed frame 10 and the sash frame 20 with heat-insulating webs 3,13 is a feature of the exemplary embodiment. Both the fixed frame 10 and the sash frame 20 could consist of a uniform profile made of metal or plastic, the latter optionally with a metallic reinforcement. In the exemplary embodiment, a so-called three-part or hinged band is shown. However, it could also be a simple two-part band.

The frame profile 1 comprises a rectangular

ge Kanuner 4, into which the two block-like hinge parts 31', which together form the frame hinge part, fit exactly with their floor plan. The hinge parts 31'/31' extend below and above the sash hinge part

32 and hold the hinge pin 25, which is held in the hinge parts 31' in the manner shown in Fig. 3 by transverse grub screws 26 engaging in circumferential grooves 25' of the hinge pin. The sash hinge part, designated as a whole by 32, is pivotably mounted on the hinge pin 25 between the hinge parts 31' of the frame hinge part 31 about the hinge axis A and is attached to the sash frame 20. The hinge parts 31' of the frame hinge part 31 are attached by means of horizontal screws 46, which pass through the wall 6 of the frame profile 1 facing away from the frame opening and running into the depth and are not visible from the visible side (Fig. 2).

The design of the sash hinge part 32 is particularly evident from Fig. 2 and 5. It comprises an angle part 33 with an angle leg 34, which at its free end engages the hinge pin 25. The hinge pin 25 is located close to the front wall 2 of the frame profile 1 in the chamber 4, which is located on the opening side of the sash 20. In addition, the hinge pin 25 is offset from the middle of the chamber 4 to the side remote from the frame opening. The left leg 34 extends from the hinge pin 25 in the chamber to the rear, i.e. to the outside remote from the opening side. The apex of the angle part

33 is located in the area of the left outer corner of the frame profile 1 according to Fig. 2 or 5. The other angle leg 35 extends towards the fold area 50 and encloses with its center line with the center line of the angle leg 34 in the embodiment an angle 36 (Fig. 5) of about 45 ⁰ C. However, the angle leg 35 is not straight, but is cylindrical on its inner peripheral surface 35' and on its outer peripheral surface 35" and coaxial with the hinge axis A. At the free

At the end, the angle leg 35 extends through a recess 37 in the wall 7 of the frame profile 1 which extends into the depth and faces the rebate area 50. In the area of the penetration through the recess 37, the angle leg 35 is bent and has on the end part 38 engaging in the rebate area 50 on the side facing the front wall 2 a separating surface 39 which is parallel to this or the frame surface and which rests against a corresponding separating surface 40 on an angled part 41 of a leg 45 of the sash hinge part 32 which engages from the front into the rebate area 50. The separating surfaces 39, 40 are flat and provided with a toothing 42, wherein the vertices of the teeth run parallel to the hinge axis A (Fig. 5). The parts 38,41 are connected to one another by screws 43 (only indicated) which extend perpendicular to the separating surfaces 39,40 and can be adjusted relative to one another in a plane perpendicular to the hinge axis A and parallel to the sash plane. This adjustment allows the position of the sash to be adjusted in the frame plane.

The leg 45 rests with its side surface 45' on the outside 14' of a wall 14 of the casement profile 11, which extends essentially perpendicular to the front wall 12 and faces the rebate area 50. The surfaces 14' and 45' are also serrated parallel to the hinge axis, so that the leg 45 can be brought into different positions perpendicular to the front surface 12. The leg 45 is fastened perpendicular to the surfaces 14', 45' by screws 15 which pass through the leg 45 and the wall 14 and which engage in threaded holes in a fastening piece 16 arranged inside the casement profile 11, the side surfaces of which approach one another in a wedge shape towards the head 15' of the screws 15.

In the side wall 14, a recess or groove is machined that extends parallel to the hinge axis A, the side surfaces or flanks 17' of which are inclined in accordance with the side surfaces 16'.

When the fastening screws 15 are tightened, the fastening piece 16 is pulled into the recess or groove without play, thereby positioning the fastening screw 15, which passes through the leg 45 in the bore 27 (Fig. 5) with a clearance that allows adjustment in the depth direction.

The sash frame profile 11 is a cover profile, which overlaps the frame profile 1 with its outermost profile part facing the fixed frame 10, the cover rebate 21. The front wall 12 of the sash frame profile 11 is therefore offset inwards from the front wall 2, namely by the so-called cover dimension 22 (Fig. 2). A C-groove 23 is formed in the cover rebate 21 of the sash frame profile 11, in which the foot 24' of a seal 24 is accommodated, which rests with a lip or the like against the front wall 2 of the frame profile 1 when the sash is closed and creates the seal. Depending on the setting of the interacting teeth on the surfaces 14' and 45', the cover dimension 22 and thus the pressure force of the seal 24 can be adjusted.

When the sash is closed, as shown in Fig. 1 and 2, the parts of the band 30 cannot be seen from the visible side, i.e. the inside. For this reason, the outline of the band 30 in Fig. 1 is only indicated by dashed lines.

For opening the sash, it is important that the essentially flat inner side 34' of the angle leg 34 of the angle part 33 is inclined at an angle 28 of approximately 20° to 30°, in the embodiment 22.5°, starting from the hinge pin 25, outwards, i.e. away from the frame opening, when the sash is closed. In this way, the angle leg 34 located in the chamber 4 can cover a swivel angle exceeding 90° before its inner side comes to rest on the back of the front wall 2. This state is indicated in dashed lines in Fig. 2. The possible swivel angle

of the angle part 33 or the sash hinge part 32 corresponds to the possible opening angle of the sash. Thanks to the design of the inner peripheral surface 35' of the angle leg 35 as a cylindrical surface, when the sash approaches the opening position, it moves over the remaining opening angle close to the boundary 37' of the recess 37 located on the right edge of the frame profile 1 in Fig. 2. The same applies to the outer cylindrical peripheral surface 35". Despite the fact that part of the sash hinge part 32 is accommodated in the frame profile 1 and the need to reach out of the frame profile 1 with the other part 38, 41, 45 over a considerable swivel angle, the recess 37 can be kept small and the closedness of the hinge arrangement can be achieved when the sash is closed.
