Abstract

So that one and the same bearing can be used for the wing end (14) of a swivel arm (4) of a wing (2), especially of a so-called skylight wing, irrespective of the height of a wing overlap (41 or 45), the bearing element (15) having a bearing journal (10) is held on a bearing part (12 or 13) so as to be displaceable transversely relative to the frame plane and lockable. According to the invention, the adjustment is carried out via a threaded connection (21), by means of which the bearing element (15) can be displaced in a transverse guide (16) of the bearing part (12 or 13) towards the wing (2) or away from this. Furthermore, the wing end of the swivel arm (4) can be coupled via an automatically acting journal-locking device (54) to the bearing journal (10) and be uncoupled from this as a result of the actuation of a release button (68). <IMAGE>

Description

The invention relates to a bearing according to the preambles of independent claims 1 to 3.

A bearing for a skylight opener is made known from DE-U-72 25 330.

This warehouse is a warehouse for a skylight opener on which the opening arm, especially a so-called opener scissors, is articulated, this extension arm detachable is coupled. Under a skylight often very high up in the room Tilting door understood, usually around a lower one horizontal axis is tiltable and by means of at least an opening device, preferably the mentioned opening scissors, by actuating a Hand lever or a crank tilted and can be closed again.

If the sash and therefore usually also the frame or fixed frame built from wooden profiles and he also with is equipped with a so-called rollover, so the geometric bearing axis for the wing side End of the extension arm from the inner surface of the wing a comparatively short distance to have. This distance increases with profiles, in particular made of aluminum profiles Frame. If you have one instead so-called smooth flapping wings, i.e. one Wing with no flap in front of it, that is Distance of the geometric axis from the inner wing surface even bigger.

To all these frame constructions To be able to take into account is that from DE-U-72 25 330 known bearings the bearing element move transversely to the sash or frame level - and lockable on a threaded connection Bearing part held, which is usually at the top Flügelguerholm is attached. The bearing pin engages or one at its in use position lower end, reduced in diameter Part in the transverse guide. The finding takes place axially with the help of a bearing element screwed screw, which then cas bearing part or be the slit-shaped transverse guide having thighs between the head of the Clamping screw and a collar or the thicker Part of the bearing element, if necessary under Interposition of a washer. So it is a purely frictional Connection of the bearing element to the bearing part.

This known camp allows, how said, an adaptation to different wing flap heights from zero to maximum usual wing flap thickness, however, is here the setting of a wing pressure on the fixed Frame very difficult and cumbersome to make. It should be noted that at Skylights due to a special scissor construction the geometric bearing axis of the bearing element moved perpendicular to the fixed frame plane can be. As I said, this is the attitude the wing pressure more difficult than with an arched shift of the geometric Bearing axis. On the other hand, it has to be considered that if the wing pressure is too strong Clamp connection between the bearing element and the bearing part is heavily loaded and under certain circumstances cannot withstand this burden. It can happen. that a set contact pressure changes in the course repeated operation of the skylight changed and in extreme cases the clamp connection is loosened to the extent that it is no longer usable is.

Generic bearings are known from DE-U-7 125 959.

Starting from the generic state of the art, the object of the invention is to simplify the assembly of the extension arm. This is particularly so meaningful in connection with window cleaning.

To solve this problem, the invention proposed that the bearing is designed according to the preambles of claims 1 to 3 according to the characterizing parts of these claims. After the clamp connection between the bearing element and bearing part in a known manner and a threaded connection has taken its place, which neither adjusts due to the self-locking still releases and large, from the wing pressure resulting forces can absorb on the one hand, an optimal closing of the wing is guaranteed and on the other hand permanent maintenance of the contact pressure are observed. The thread connection is like any other Threaded connection also, from a threaded bolt on one part and one nut thread on the other part. The shift movement sets that one of the two parts of the threaded connection is rotatable and immovable while the other the displacement movement causing the stroke can perform.

The one element of Threaded connection is a screw with a head, Outer band or the like. And the other element Nut thread. Use is conceivable an outer waistband in addition to the head, also around the head Diameter and thus the contact surface enlarge.

While at State of the art according to DE-U-7 225 330 the bearing element with a Pin in the slot-shaped transverse guide of the bearing part intervenes and thus rotatable and crosswise slidable to its longitudinal axis in the transverse guide is stored, the invention as well as the known from DE-U-7 125 959 bearing element in the Lateral guidance only shifted, but not by the geometric bearing element axis rotated become. Of course, this is also due the threaded connection prevented. The lateral guide but prevents due to their special Training also a tilting of the bearing element transverse to its geometric axis, if one appropriate force attacks on it.

For the rotatable but unmovable Mounting the screw on the bearing part it is sufficient according to claim 2 if it is only in one recording engages at the far end of the guide slot. The "storage" of the screw in this case, this is done exclusively on the bearing element. The bearing part needed due to good guidance of the bearing element no special Bearing hole for the screw. This makes it easier Assembly and also cheaper the manufacture of the Stock part. The screw has in on her head known way a slot, cross recess, hexagon socket or the like, on which a corresponding Actuating tool can be applied.

An opening device, in particular a so-called opening scissors, connects the upper end of a wing 2 with the associated cross member a fixed frame 3. The spars of the frame 1 made of wood or according to FIG. 2 consist of profile material, in the latter case both plastic and aluminum or the like. in Question come. An extension arm 4 (Fig. 5) is with its one end on the fixed frame 3, for example pivoted and slidable while being other end by means of a bearing 5 on the wing, more precisely, rotatable on its upper cross member is stored. As a rule, it is Raising arm 4 around an element of a scissor arm, although in the case of a larger wing also more than such opening or opening scissors Can find use. 6 are still a fixed frame side scissor stay 7 and a handlebar 6 is shown. He makes the connection between the hinge points 8 and 9 ago.

The sash end 14 of this opener scissors or the extension arm 4 is on a journal 10 stored. This is in the sense of Double arrow 11 on a bearing part 12 or 13 held adjustable. The bearing pin 10 forms to a certain extent an approach of a bearing element 15, with which it is made in one piece.

The bearing element 15 is in a transverse guide 16 of the bearing part 12 or 13 in the sense of the double arrow 11 movable. With this lateral guidance it’s a slit-like breakthrough, its longitudinal edges 19 and 20 in after opposite sides open guide grooves 17 or 18 of the bearing element 15 engage.

The bearing element 15 and the bearing part 12 or 13 are coupled via a threaded connection 21, where in the case of the embodiment Bearing element 15 the threaded bore or Has nut thread 22. A threaded bolt engages in it 23 a, which is relative to the bearing part 12 or 13 is rotatable, but is held immovably. At the Threaded bolt 23 is the threaded part a screw with head 24. So that the Screw can turn, her head is more common Way with a hexagon socket 25, slot, Phillips or the like. In which one appropriate turning tool can be inserted. Around to get a slightly larger diameter the head is rotatably connected to a disc 26. This can also be easily done on the threaded bolt 23 screwed on and opposite the head in Be tense in the sense of a lock nut. It attacks at least with your radial over the screw head protruding edge in a receptacle 27, 28 of the Bearing part 12 or 13 a.

These recordings are short Cross slots at the far end of the long edge 19 and 20 of the transverse guide 16 forming Guide slot of the bearing part 12 or 13. As can be seen, for example, in FIG. 1, is the longitudinal thread axis 29 below the Level of the transverse guide 16, which is why the disc 26 with the top of its edge in the Recording 27 engages. Also located also the screw head 24 below the plate-shaped Part 30 or 31 of the bearing part 12 or 13, the two beads 32 and 32 a in this area has on both sides of the disc 26. The gap space forms between these two beads in the embodiment the receptacle 27 for the disk 26. Additionally or alternatively, the receptacle 27 also by two short, opposite one another Laterally extending slots 28 on the far side of the wing Be formed end of the transverse guide 16.

3, the plate-shaped part 30 of the bearing part 12, the horizontal leg of a Angle, the vertical leg 33 to the ins Interior surface 34 or 44 of the upper Wing cross member 35 is attached. He is with Mounting holes 36 and 37 for mounting screws 38 equipped. Besides, is still at least one thread 39 for a fastening screw 40 provided. The thread comes with frames constructed from profiles (Fig. 2) Importance while fastening screws 38 can be used in conjunction with wooden frames. The mounting holes 36 and 37 are like this deeply arranged that the screws below a Wing flap 41 screwed into the frame wood can be.

In contrast, it is the plate-shaped Part 31 of Fig. 4 around the cranked Part of the bearing part 13. This consists essentially from a mounting plate with mounting holes 42 and the plate-shaped part 31. In contrast to the bearing part 12 on the upward-facing surface of the cross member 35 put on and screwed on there. A wing-side Extension 43 of the guide slot for the bearing element 15 is so large in cross section chosen that the latter transverse to its direction of displacement 11 used and in the through the longitudinal edges 19 and 20 formed transverse guide can be "threaded".

If you have the screw head 24 and so turns the threaded bolt 23 in one direction, this leads because of the rotatable and immovable Holding the screw, for example, to a Approach of the journal 10 to the fixed Frame 3. One turn in the opposite direction the journal 10 from the fixed frame 3. If the threaded bolt on the bearing element instead 15 is located, so it is immovable and is held non-rotatable, so causes a rotation a mother engaging in the receptacle 27, 28 or the like. Because of their rotatable but immovable Bracket or storage exactly the same.

Figure 1 removes that at a comparatively wide wing flap 41, measured across the frame plane, the bearing element 15 a shorter distance from the ins Interior wing surface 34 has as for example with an aluminum construction the case is where the bearing element 15 from the comparable wing surface 44 a greater distance has, because there the wing flap 45th is much narrower. If you instead uses a so-called smooth-beating wing, at which the wing surface 44 is flush with the frame surface 46 runs, so the bearing element 15 in the direction of arrow 47 further to the right be relocated. It also lights up easily that you can use this setting device or Threaded connection 21 the contact pressure of the wing 2 adjust precisely to the fixed frame 3 and can readjust if necessary, whereby the set position due to the self-locking Thread connection is adhered to safely. Here it does not matter whether the journal 10 when tilting the wing, i.e. when opening the Skylights, perpendicular to the fixed frame plane or in moved an arc.

As can be seen in particular from FIG. 6, the bearing pin 10 consists of a neck 48 with an attached thickened forming the free end Head 49. The latter is at least on his free end, but in the embodiment as a whole designed as a truncated cone or cone. The Transitions to the head on the one hand and to an im essential cuboid base body 50 on the other hand takes place via fillets 51 or 52. To get a slightly sharper paragraph, the fillet 51 becomes much smaller Radius executed.

The bearing pin 10 engages in one on the sash frame side End of the arm 4 held Bearing piece 53, which with a pin locking device 54 is equipped. The Bearing piece 53 consists essentially of two preferably in the longitudinal direction of the extension arm 4 mutually displaceable parts 55 and 56, between which a spring 57, in particular a Compression spring, is switched. The spring 57 holds this two parts 55 and 56 in the from the drawing apparent locking end position. In this the inserted head 49 of the journal 10 held.

The one bearing piece part is in particular as an approximately U-shaped housing 56 trained, on the U-Mittelsteg there is one End of the spring 57 is supported. The other Bearing piece part is one in the sense of the double arrow 58 sliding guide body 55. Er can be associated with a recording for the Be end of the spring 57 equipped.

The raising arm 4 has, at least in the exemplary embodiment, a U cross section. Between his two U-legs 59 and 60 becomes the bearing piece 53, more precisely his housing 56 inserted.

The height of the housing 56 essentially corresponds the clear distance between the U-legs 59 and 60. There are also two in line with the latter Bores 61 and 62 attached, in which a bolt-shaped element, in particular a rivet 63, is inserted. It passes through a bore 64 of the guide body 55 and thus connects the the latter with the extension arm 4 immovable. Rotation is also not possible because of the edges 65 and 66 of the housing 56 on the inside of the U-cross bar 67 of the extension arm 4 abut.

The two U-legs 59 and 60 are on Housing 56 is not tight, but the latter can not only relative to the guide body 55, but also with respect to the extension arm 4 in the sense of Double arrow 58 are moved. His after The protruding ends form a release button 68. If the latter in the sense of arrow 69 presses against the resistance of the spring 57, so you can extend arm 4 in the direction of the arrow 70, i.e. detach from the journal 10. The Coupling the extension arm to the bearing journal is based on the following Construction automatically when you open the extension arm against arrow 70 on the bearing journal 10 touches down and depresses.

On the two U-legs 59 and 60 of the Extension arms 4 are aligned holes 73 and 74. Holes of the same size are 75 and 76 on the U-legs 71 and 72 of the housing 56 the device 54 attached. Finally located such a bore 77 also on the guide body 55. In the mounting position of the journal 10, all of these holes 73 to 77 are congruent. The bore diameter corresponds approximately the largest diameter 78 of the journal 10th

The holes 75 and 76 of the housing U-legs 71 and 72 are 69 in the direction of displacement extended like a keyhole. The one in the drawing upper extension 79 can be in the locked position the free end of the journal 10 or be associated with his thickened head 49 while in the lower extension of the neck 48 of the Bearing pin 10 engages. The thickened head 49 can also be completely in the Bore 77 of the guide body 55 are. On is due to the laterally shifted case Position of the hole in relation to the holes 74 and 76 pulling out the bearing pin 10 contrary to arrow 70 not possible. The side Offset of the holes is chosen so that the free end of the journal 10 despite the locking position of the guide body enter and push the latter away to the side until it locks can.

From Fig. 5 it can be seen that on the two U-legs 71 and 72 of the housing 56 recesses 80 are attached, which the necessary Slidability of the housing 56 against allow the rivet 63. It goes without saying between parts 55 and 56 of the pin locking device 54 a sufficient distance 81 available, which is pressing the release button 68 enables.

The housing 56 is expediently the Device 54 made of the same material like the extension arm 4, for example made of metal, especially made of anodized aluminum. The same thing applies to one on the other end of the extension arm inserted end part 82. In contrast one manufactures the guide body 55 preferably made of a stable plastic.

It remains to be added that the Screw 40 for fastening the bearing part 12 on To a certain extent screwed in wing 2 from the inside, so that her head does not when the wing is closed is accessible and also an optically favorable Training arises. An advantage of the one described above Construction is that one now independent of the rollover heights can use the same construction and one by replacing only a single part, namely the bearing part 12 or 13, another Can choose stroke type. This will result in a reduction of warehousing and on the other hand one Expansion of the series reached. The whole construction is also characterized by a very advantageous Look from what it is all about fittings general and in particular with so-called skylights arrives. The correct position of the opener and the desired contact pressure can be found at closed wing by turning the screw 23, 24 easily and quickly. Moreover the bearing part is equally suitable for assembly Wooden and on plastic or aluminum windows suitable. By screwing in the fastening screw 40 from the inside there is no longer the usual Insert a retaining strip with threads in the Flap of the wing. The threads are now instead on the vertical leg 33 of the bearing part 12.

The offset 83 ensures that the bearing element 15 the same position to the scissors or to the extension arm 4 as in the version with angular bearing part 12. The training of the neck 48 of the bearing pin 10 with the Fillets 51 and 52 allow the necessary Inclined position in relation to the extension arm 4 tilted wing 2.

Furthermore, it can be seen from Fig. 6 that the Distance of the guide body 55 from the handlebar 6 and / or from the fixed frame-side scissor bearing 7 when the wing is closed is so low that the Release button 68 not actuated and thus the extension arm 4 cannot be unhooked. To this Manipulations in this area become wise safely prevented. Otherwise you can see the position of the release button 68 from below, whether the wing is properly hooked in or the extension arm 4 is correctly coupled or not. Should this Coupling has not been carried out correctly you cannot close the wing completely and is automatically due to this lack attentive. This undoubtedly increases security for this window. Furthermore, they are scissor bearings 7 and the handlebar 6 and the pin locking device 54 designed and each other assigned that with the housing 56 jammed Trigger button 68 through the scissor stay or Handlebar is pressed into the locked position.
