Description

The invention relates to a displacement arrangement for displacing a sash of a window or a door transversely to the main plane of a fixed frame of the window or the door according to the preamble of patent claim 1. The invention further relates to a window or a door with such a displacement arrangement.

From the EP 2 829 679 A1 a displacement arrangement mentioned at the outset has become known which has a guide part which can be fixedly arranged on a wing and a first control part guided on the guide part. The first control part has a curved first control link in which a first control projection is guided, the first control projection being firmly connected to an actuating mechanism in the form of a drive rod.

The WO 2007/139354 A1 discloses an actuating mechanism in the form of a drive rod on which a roller arrangement is mounted, the drive rod being received in a guide profile with a U-shaped cross section. The guide profile has curved control slotted links in which control projections are guided, the control projections being firmly mounted on connecting rods. The control projections can have roller bearings in order to reduce the friction between the control projections and the control link.

From the WO 2012/093382 A1 a displacement arrangement has also become known which has a control projection, the control projection being guided in a control link. To reduce the friction between the control projection and the control link, a roller bearing is arranged on the control projection.

The DE 10 2014 220 837 B3 discloses a displacement assembly having a roller assembly. The roller arrangement comprises a guide part which can be arranged on a wing and a first control part with a roller which can be displaced relative to the guide part. Several roller bearings are provided between the first control part and the guide part.

From the CN 105 909 155 A a generic displacement arrangement for displacing a sash of a window or a door transversely to the main plane of a fixed frame of the window or the door has become known.

It is thus known to reduce the friction during the actuation of the displacement arrangement by arranging a roller bearing between the control projection and the control link. Nevertheless, it has been shown that, in particular, very heavy sashes with multiple glazing can only be disconnected from the fixed frame with forced control with difficulty. Furthermore, with the known solutions, only a limited contact pressure can be generated with user-friendly operators.

The object of the present invention is therefore to provide a displacement arrangement which enables a user to make wing movements easier. It is a further object of the present invention to provide a window or a door with such a displacement arrangement.

This object is achieved by a displacement arrangement according to claim 1 or a window or door according to claim 9. The sub-claims reproduce preferred developments.

The object according to the invention is thus achieved by a displacement arrangement for a sash of a window or a door, the sash being able to be parked in a positively controlled manner from the fixed frame by operating an actuating mechanism of the displacement arrangement. The relocation order has a first control projection and a first control link, the first control projection engaging the first control link. The first control link runs at least in sections at an angle to the main plane of the wing, the main plane of the wing in particular coinciding with the plane spanned by the actuating mechanism. A displacement of the first control projection by means of the actuating mechanism causes a movement of a control part of the displacement arrangement, so that the sash can be set down from the fixed frame. The displacement arrangement also has a guide part which can be fixedly arranged on the wing. The first control projection is partially guided in a first guide slot which is formed in the guide part. The first guide link preferably runs in the main plane of the wing or parallel to the main plane of the wing. The first control projection has a first roller bearing in the area of the first guide slot, which can be supported on the first guide slot when the actuating mechanism is actuated. The control part is preferably displaceable transversely to the main plane of the wing.

The invention is based on the knowledge that the operation of the actuating mechanism is significantly facilitated if the sliding friction of the first control projection on the guide part is eliminated. This sliding friction has so far been neglected, since it was assumed that significant friction losses only occur between the first control projection and the first control link. However, it has been shown that, especially with high contact pressure of the sash on the fixed frame (and the resulting compression of a seal between the sash and the fixed frame), the friction between the first control projection and the first guide slot accounts for a large part of the resistance of the actuating mechanism User. The arrangement of the first roller bearing between the first control projection and the first guide slot therefore significantly facilitates the operation of the displacement arrangement.

The first roller bearing can be designed in the form of a ball bearing or needle bearing. The first roller bearing can have an outer ring made of metal. As an alternative or in addition to this, the first roller bearing can have an additional body, in particular in the form of an additional outer ring, made of plastic. In this case, the outer ring of the first roller bearing can be coated with plastic.

In the first guide slot, the first roller bearing preferably has a play of less than 2 mm, in particular less than 1 mm, preferably less than 0.5 mm, more preferably less than 0.2 mm, particularly preferably less than 0, 1 mm.

According to the invention, the first control projection is arranged or formed on the actuating mechanism and the first control link is arranged or formed on the first control part. This enables a particularly simple construction of the displacement arrangement.

The first control part can be guided on the guide part in such a way that it can only be moved in one direction relative to the guide part. The control part is preferably movable relative to the guide part exclusively perpendicular to the main plane of the wing.

The first control part can be rotatably mounted on the guide part. The axis of rotation is preferably arranged parallel to the main plane of the wing or in the main plane of the wing.

The displacement arrangement can have a roller arrangement connected to the control part on the lower side of the displacement arrangement and / or a support arrangement on the upper side of the displacement arrangement. The support arrangement can have a roller with an axis of rotation, the axis of rotation being aligned in particular in the main plane of the wing.

In addition to the first roller bearing, the first control projection can have a second roller bearing in the area of the first control link in order to minimize the friction losses between the first control projection and the first control link. The second roller bearing can be designed in the form of a ball bearing or needle bearing. The first roller bearing and the second roller bearing are preferably of identical design.

More preferably, the displacement arrangement has a roller support bearing which is arranged or formed between the guide part and the control part. The support roller bearing can be designed in the form of a ball bearing or - preferably - in the form of a roller bearing with several needle rollers.

The displacement arrangement can have a second control projection which engages in a second control link and is guided in a second guide link of the guide part. The second control link is formed at least in sections at an angle to the main plane of the wing. The second guide link preferably runs in the main plane of the wing or parallel to the main plane of the wing.

The first roller bearing of the second control projection preferably has a play of less than 2 mm, in particular less than 1 mm, preferably less than 0.5 mm, more preferably less than 0.2 mm, particularly preferably less, in the second guide slot than 0.1 mm.

The second control projection preferably has a first roller bearing for supporting the second control projection on the second guide slot. As an alternative or in addition to this, the second control projection can have a second roller bearing to support the second control projection on the second control link.

The first roller bearing of the first control projection can be designed in the same way as the first roller bearing of the second control projection. The second roller bearing of the first control projection can be designed like the second roller bearing of the second control projection. The first control projection is preferably designed in the same way as the second control projection.

The object according to the invention is also achieved by a window or a door with a fixed frame, a sash and a displacement arrangement as described above. The guide part can be permanently mounted on the wing.

The wing is preferably designed in the form of a sliding wing, which can be set down, in particular parallel, from the fixed frame and is displaceable parallel to the fixed frame.

Further features and advantages of the invention are illustrated in the following detailed description by way of several exemplary embodiments of the invention. The various features can be realized in any combination in variants of the invention without departing from the scope defined in the appended claims. The features shown in the drawing are shown in such a way that the special features according to the invention can be made clearly visible.

Fig. 1 shows a displacement arrangement 10 with an actuating mechanism 12 designed as a circumferential drive rod fitting which can be operated via an actuating handle 14. The actuation mechanism 12 is on a / a in the Figs. 4 and 5 window or door shown and extends along the fold circumferential direction 16. The fold circumferential direction 16 extends in the main plane 18 (in Fig. 1 only indicated) of the window or door. In the exemplary embodiment shown, the displacement arrangement 10 has two points a, b with a roller arrangement 20a, 20b and two points c, d with a support arrangement 22a, 22b, the Roller arrangements 20a, 20b and the support arrangements 22a, 22b can each be displaced transversely to the circumferential direction 16 of the fold.

Fig. 2 shows part of the components of section II according to FIG Fig. 1 . It can be seen that the actuation mechanism 12 has a bolt-shaped first control projection 24a which engages in a first control link 26a which is designed in the form of a first control slot. The first control link 26a is formed at least in sections at an angle to the circumferential direction 16 of the fold. When the actuating mechanism 12 is displaced in the fold circumferential direction 16, the roller arrangement 20a is displaced perpendicular to the fold circumferential direction 16. The first control link 26a is formed in a control part 28.

The roller arrangement 20a has at least one roller 30a, 30b. In addition, the roller arrangement 20a has a support roller 32 in the present case. The support roller 32 has an outer diameter which is greater than the width of the rest of the roller arrangement 20a. In this way, by supporting the support roller 32, transverse forces on the roller arrangement 20a can be avoided.

Fig. 3 shows a representation of the detail III according to Fig. 1 . The support arrangement 22a also has a support roller 32 which is arranged around a vertical axis of rotation. Analogous to the structure according to Fig. 2 If the displacement arrangement 10 has a control part 28 with a first control link (not visible) in the area of detail III, into which a first control projection 24a engages. Furthermore, the displacement arrangement 10 has a guide part 34, which in the displacement arrangement 10 according to FIG Fig. 2 is not shown. The guide part 34 is immovable on the wing 40 (see Figs. 4, 5 ) assembled. To reduce the friction when operating the actuating mechanism 12, the first control projection 24a is mounted in the circumferential direction 16 of the fold on a first guide slot (not shown) in the guide part 28. The first Control projection 24a passes through guide part 34 and engages control part 28.

Fig. 4 FIG. 11 shows a view from the locking side of a window or door 36 with a fixed frame 38 and a leaf 40. The actuating mechanism 12 is mounted on the leaf 40. This is supported on a running rail 42 via the roller arrangement 20a. There is a gap 44 between the wing 40 and the fixed frame 38. The wing 40 accordingly does not lie against a circumferential seal 46 of the fixed frame 38.

The support roller 32 rests on a guide 48 of the fixed frame 38, which guide is designed as a vertical web. In the position shown, the wing 40 can be displaced with respect to the fixed frame 38, the support roller 32 being supported on the guide 48 or being able to roll on it.

In the upper area of the window or door 36, the fixed frame 38 also has a guide 48, which here is designed like a groove. In the guide 48 is the support roller 32 (see also Fig. 3 ) guided.

Fig. 5 12 shows the window or door 36 after the actuation mechanism 12 has been operated. By actuating the actuation mechanism 12, the roller assemblies (in Fig. 5 the roller assembly 20a is visible) and the support assemblies (in Fig. 5 the support arrangement 22a is visible) displaced. This means that the wing 40 approaches the fixed frame 38 so that the seal 46 is pinched and compressed between the wing 40 and the fixed frame 38.

Fig. 6 shows a further detailed view of the displacement arrangement 10 according to detail II of FIG Fig. 1 . Out Fig. 6 it can be seen that the first control projection 24a has a cylindrical shape and is arranged on the actuating mechanism 12. The first control projection 24a has a first roller bearing 50 and a second roller bearing 52. The first roller bearing 50 serves to guide the first control projection 24a with little friction in a first guide slot 54a of the guide part 34. The second roller bearing 52 serves to guide the first control projection 24a with little friction in the first control slot 26a of the control part 28.

The first guide slot 54a is formed in the direction of the circumferential fold direction 16 or parallel to the circumferential fold direction 16, whereas the first control slot 26a is formed at least partially transversely to the circumferential fold direction 16. The roller arrangement 20a is arranged on the control part 28. The displacement arrangement 10 is in the area of detail III (see Fig. 3 ) designed analogously to this, the control part 28 instead of the roller arrangement 20a the support arrangement 22a (see Fig. 3 ) having.

The guide part 34 is fixed, ie rigid and immobile, on the wing 40 (see Figs. 4, 5 ) can be arranged, screwed on here. How out Fig. 6 As can be seen, a guide 56 is provided between the guide part 34 and the control part 28, which only allows a limited movement of the control part 28 relative to the guide part 34 transversely to the fold circumferential direction 16. In the present exemplary embodiment, the guide 56 is designed in the form of a dovetail guide.

Fig. 7 shows a further example of a displacement arrangement 10. The displacement arrangement 10 has a first control projection 24a and a second control projection 24b. The control projections 24a, 24b are identical. Furthermore, both control projections 24a, 24b are identical to the first control projection 24a according to FIG Fig. 6 educated. Both control projections 24a, 24b are arranged on the actuation mechanism 12.

The first control projection 24a is guided in a first guide slot 54a, here open on one side. The second control projection 24b is in one, here also open, second guide slot 54b out. Furthermore, the first control projection 24a engages in a first control link 26a and the second control projection 24b in a second control link 26b. When the displacement arrangement 10 is actuated, the first control projection 24a emerges from the connecting links 26a, 54a assigned to it. Shortly before this exit, the second control projection 24b enters into the connecting links 26b, 54b assigned to it, so that continuous guidance of the control part 28 (see FIG Figs. 8, 9 ) given is. The embodiment described here is analogous to FIG DE 10 2014 220 837 B3 , the content of which is fully referred to.

Fig. 8 shows a cross section of the displacement arrangement 10 in area VIII (see Fig. 7 ). Out Fig. 8 the guidance of the first roller bearing 50 on the first guide part 34 and the guidance of the second roller bearing 52 on the control part 28 can be seen. The horizontal play of the first control projection 24a in the guide part 34 and in the control part 28, which is made up of the distances A and B (in Fig. 8 indicated enlarged for clarity) is less than 0.5 mm. Ideally, the game tends towards zero. The inner rings of the roller bearings 50, 52 are spaced apart by a spacer ring 58.

Fig. 9 shows a cross section of the displacement arrangement 10 in the area IX (see Fig. 7 ). Out Fig. 9 it can be seen that a support roller bearing 60 is arranged between the control part 28 and the guide part 34. This means that very heavy wings 40 (see Figs. 4, 5 ) be supported with low friction.

Taking all the figures of the drawing together, the invention relates in summary to a displacement arrangement 10 for moving a sash 40 of a window or a door 36 transversely to the fixed frame 38 of the window or door 36. The displacement arrangement 10 has a means of indirectly supporting the transverse movement Control part 28, which by means of a Actuating device 12 is moved relative to a guide part 34 which can be fixedly mounted on the wing 40. Between the control part 28 and the actuating device 12, a first control projection 24a is provided, which engages in a first control link 26a of the control part 28 and at the same time in a first guide link 54a of the guide part 34. The first control projection 24a has a first roller bearing 50 for bearing on the first guide slot 54a. In addition to this, the first control projection 24a can have a second roller bearing 52 for support on the first control link 26a. Alternatively or in addition to this, a roller support bearing 60 can be provided between the guide part 34 and the control part 28. The displacement arrangement 10 enables a high contact pressure of the sash 40 to be generated against the fixed frame 38 with moderate operating forces and thus a good sealing of the window or door 36. Furthermore, even heavy sashes 40 can be put down with very little friction by operating the actuating device 12 a user of the window or the door 36 is possible.
