Description

[0001] The invention relates to a hinge for a door or window according to the preamble of claim 1.

[0002] Such a hinge is already known from EP 3529440 B1. The hinge consists of a frame part and a sash part. The sash part and the frame part are mounted separately to the sash and frame. The frame part consists of a mounting section and a coupling piece pivotally mounted to it. The coupling piece has a hinge flap that is flat and rectangular, forming a tongue with a tapered end and two open-edged retaining recesses opposite each other on parallel side edges. Hinge pockets are attached to the sash in recesses. To attach the sash to the frame, the hinge pockets, which move together with the sash, are slipped over the hinge flaps, and the sash is then lowered. This causes a retaining projection located in the sash part to engage in the upper retaining recess of the hinge flap. The retaining projection can be moved horizontally by means of an adjusting device, so that the hinge flap can be adjusted relative to the hinge pocket.As long as the sash's weight presses the hinge pocket with the retaining projection into the retaining recess, the sash is secured. To prevent the retaining projection from being dislodged from the retaining recess, an anti-lift device is provided.

[0003] The SIEGENIA-Axxent hinge system, apparently used in June 2011, employs a PFVP7000 hinge pocket. The anti-lift device consists of a cover plate attached to the front of the lower end of the hinge pocket. A section of this cover plate protrudes into the hinge pocket opening, partially closing it. This prevents the hinge leaf from being lifted further by causing it to strike the cover plate. The cover plate must be manually installed.

[0004] Therefore, EP 3529440 B1 specifies a clamping element which is movably mounted in the tape pocket against a spring force in the insertion direction of the tape leaf. When the flap with tape pockets is slid over the tape leaves, the tape leaf pushes the clamping element backward into the pocket. When the flap is lowered, the tape leaf releases the clamping element, which is then pushed toward the fold by the spring force. The clamping element then engages the tape leaf with a key-bit-like projection. This limits the movement of the tape leaf within the tape pocket. For this to work, the clamping element must be movably guided within a guide in the tape pocket. Therefore, the clamping element has the cross-sectional shape of a key with a bit. The cylindrical section forms the guide for the clamping element, and the compression spring, which must also be housed within the guide, acts upon this section.

[0005] The design therefore consists at least of the spring and the clamping element. The movable clamping element must be mounted in the guide and requires additional space behind the tape pocket. Since the guide and the clamping element are attached to the lower end of the tape pocket, dirt and abrasion can impair the movement of the clamping element. Furthermore, the design is quite complex to assemble and has the disadvantage that, in the embodiment described above, the clamping element supports the tape flap over a small portion of its length. To prevent this, EP 3529440 B1 provides additional means, for example, in Figures 4 and 7.

[0006] From DE 20 2017 005 348 U1 a belt corresponding to the apparent prior use SIEGENIA-Axxent has become known, in which an additional adjustment device is proposed.

[0007] The invention is based on the objective of avoiding the disadvantages of the prior art and providing a simple, easy-to-install anti-lift device that is activated without manual intervention and consists of few components.

[0008] The invention provides a solution by using a clamping element that is spread apart by the tape flap when it is inserted, allowing a vertical displacement of the tape flap until the tape flap interacts with the retaining projection and the clamp engages the tape flap with the support section.

[0009] This design requires only the spring to be provided in the belt pocket. When the belt flap is inserted, the spring moves laterally through a horizontal movement and does not occupy any space in the rear of the belt pocket. In the simplest case, the invention therefore provides a spring with only one leg, which, when the belt flap is inserted, moves laterally and elastically, and springs back into the space freed up when the flap is lowered.

[0010] A further development proposes that the clamp be U-shaped. This achieves greater stability while maintaining the basic function.

[0011] For the latter design, it is advantageous if the two legs return horizontally to the relaxed position in the securing position in order to be able to securely grip the ligament flap.

[0012] A simple yet stable design is achieved when the spring is formed from a strip of leaf spring arranged vertically in the band pocket.

[0013] To ensure that the strap flap is reliably supported, the spring is designed to have an arc in a central section that points towards the center of the strap pocket.

[0014] To deactivate the anti-lift device, for example in the event of disassembly, it is sufficient to insert a suitable tool into the area of ​​the spring. However, it is advantageously suggested that a switch be arranged in the strap pocket, which deflects the clamping element into a release position as needed.

[0015] The drawings illustrate further advantageous designs. They show: Fig. 1 shows an overall view of a band consisting of a wing band section and a frame band section; Fig. 2 shows a sectional view of the band along line II-II in Fig. 1 , Fig. 3 a general view of the mounted tape with the tape pocket partially open.

[0016] In the Fig. 1 A hinge 1 consisting of a sash part 2 and a frame part 3 is shown. The sash part 2 consists of a rebate rail 4 and a hinge pocket 5 attached to it. The rebate rail 5 is fixed to the rebate of the sash (not shown) by means of fastening screws.

[0017] From the Fig. 2It is evident that the frame part 3 has a hinge axis 6 and terminates in a hinge leaf 8 with an angled cantilever arm 7. The hinge leaf 8 is designed for coupling with the sash part 2. The hinge pocket 5 has a hinge pocket opening 9 for this purpose, which is open towards the frame rebate. The width of the hinge pocket opening 9 is adapted to the dimensions of the hinge leaf in its upper part. In the exemplary embodiment, the clamp is U-shaped and symmetrical with respect to a horizontal insertion direction E. The hinge pocket 5 forms a housing for the hinge leaf 8 and the clamping elements and adjusting pieces arranged therein, as will be shown below.

[0018] As the Fig. 3 As shown, the belt pocket 5 is equipped with a clip 10 in its lower section. In the exemplary embodiment, the clip 10 is shown according to... Fig. 2 U-shaped and supported on a lower horizontal wall 11. According to the Fig. 2The clamp 10 is formed from a leaf spring strip and has an arc-shaped course in the middle area, in which the two legs 12, 13 of the clamp 10 approach each other.

[0019] A changeover element 14 is located between the legs 12, 13 of the clamp 10. The changeover element 14 is designed as a flat strip in one plane. The thickness of the flat strip is less than the thickness of the band flap 8 in this direction. In the plane transverse to this, the changeover element 14 is provided with three reinforcements 15, 16, and 17. The reinforcement 16 is positioned such that it lies between the smallest distance between the two opposing arcs of the clamp 10, while the reinforcements 15 and 17 are located near the ends of the changeover element 14. The reinforcements 15, 16, and 17 are symmetrical with respect to a longitudinal center axis of the changeover element 14, and their dimensions widen the changeover element 14 to a size that is slightly larger than the thickness of the band flap 8.This design gives the changeover switch 14 a first flat rectangular shape and, in the plane running transversely to it, a flat rectangular contour with two elongated constrictions between the reinforcements 15, 16, 17. The changeover switch 14 can be pivoted by means of a tool engagement not shown here.

[0020] The hinge mechanism functions as follows: The sash, to which the hinge pocket 5 is attached, is moved towards the frame part 3 in the insertion direction E. The sash part 2 is then slipped over the hinge flap 8. The hinge flap 8 thus enters the hinge pocket opening 9. In order to pass the retaining projection 18 of the adjusting piece 19, which projects into the hinge pocket opening 9, the sash is raised until the hinge flap 8 is guided along the lower wall 11. During this process, the hinge flap 8 pivots its legs 12 and 13 outwards.

[0021] When the sash is lowered, the retaining projection 18 engages in the retaining recess 20 of the hinge leaf 8. The legs 12, 13 spring back, and their longitudinal edges engage under the upwardly displaced hinge leaf 8 in the area of ​​the opposing arches. The legs 12, 13 then strike the changeover switch 14, producing a distinct click that signals to the user that the anti-lift device is activated. The legs 12, 13 are then supported against the lower wall 11. The retaining projection 18 can therefore no longer disengage from the retaining recess 20 of the hinge leaf 8. The clamp 10 forms a clamping element 21. The sash is thus secured against being lifted out.

[0022] To disassemble the wing again, the adjuster 14 can be pivoted by 90°. In doing so, the adjuster 14, with its reinforcement 16, spreads the clamp 10 and is held in this position by the clamp 10. The hinge leaf 8 can now move freely between the pivoted legs when the wing is lifted.

[0023] The in the Fig. 2 The illustrated embodiment shows a U-shaped clamp 10. In contrast, the clamp 10 can also be equipped with only one leg, which is initially swung out laterally by the band flap during assembly and swings back into its clamping position due to the elastic restoring force when the wing is lifted.

[0024] As from the Fig. 2As can be seen further, the folding rail 4 forms a recess 22 open in the direction of the fold, into which the tape pocket 5 sits with a flange 23. The folding rail 4 thus forms a stationary bearing for the tape pocket 5, which allows adjustment of the tape pocket 5 relative to the folding rail 4 via adjusting means such as eccentric pins.
