Description

The invention relates to a bearing element of an upper Pivot bearing according to the preamble of claim 1. Such Bearing element is known from DE-A-4040233.

Similar upper pivot bearings are in connection with rotating blades or turn and tilt sashes of windows, doors and the like e.g. known from FR-A-2 284 739. The wings are there either left or right hinged. For both However, one and the same pivot bearing should be used be usable. As a result, this upper pivot bearing be convertible so that it can be used depending on the type of attack Wing can adjust what by turning the folding band compared to the vertical holding arm of this upper pivot bearing he follows. After reaching the rotary end position the latter be secured accordingly. You achieve this with one previously known upper pivot bearing of the type described above in that a locking spring is inserted, the Folded tape connects to the holding arm. The connection of The holding arm and folding tape are made using a screw connection, which must also absorb high tractive forces.

From the earlier application EP-A-590 258 it is known on Retaining arm recesses and one piece with the folding tape projecting lugs to be provided in the recesses can intervene. In the event of signs of fatigue The entire bearing element must be replaced by a snap-in connection will.

From DE 30 24 746 A1 an opening device for Tilt-swing wing became known. There is one Locking of the folding tape over a cam, which in a Recess engages. It is considered disadvantageous here that the cam wears out relatively quickly and the Spring force mainly from the bolt connection of the Folding tape depends on the holding arm. Are the two Holding projections of the pin worn out, then the loses Fogged up its pretension completely. A safe one Bracket is then no longer guaranteed.

DE 40 40 233 A1 shows a pivot bearing on one Opening device of turn-tilt sashes of windows, Doors or the like, which is rotatable. The Swivel bearing can be locked in two end positions by a spring-loaded bolt into a locking opening intervenes. The spring element is at the end of the horizontal Extension arm provided. Such spring elements are in the Usually unstable and cannot absorb high forces.

There is now the task of a generic upper one To further develop the pivot bearing so that the setting on Left or right stop without tools can be and which can also absorb high forces.

To solve this problem, the invention proposed that the upper pivot bearing according to the preamble of claim 1 corresponding to the characterizing part of this Claim 1 is formed.

The folding tape is also located in this upper pivot bearing when shipping in a neutral rotary liner. Of the The window maker only has to check whether the sash to be struck right or left and accordingly the folding tape in one of the two possible rotary end positions rotate. Starting from the shipping neutral position an approximately 90 ° turn is sufficient for this. In the rotary end position there is an automatic locking of the folding tape opposite the vertical holding arm due to the locking member its spring load in the then assigned recess or the like occurs. The spring force must be chosen in this way be that the locking member with normal operation of the Wing can not emerge again. On the other hand, you can but - if a possibility is provided for this - by acting on the locking element against the locking direction release the catch and especially if the folding tape inadvertently in wrong before assembly Direction has been reversed, this error again correct. High forces can be taken over because the Folding tape is gripped behind by the holding arm.

The latch is on a resiliently bendable arm. This must with regard to the vertical holding arms so that it is only the can perform the intended bending movement. In this respect sees a development of the invention that the locking member to the free end of the resiliently bendable arm is integrally formed, the end remote from the latching member on vertical arm is held. The held end of the bendable arm is by means of the axis of rotation of the folding tape held. This allows then take advantage of the axis of rotation in two ways what the compact design and inexpensive manufacturing benefits is coming.

A particularly preferred embodiment of the invention results from claim 4. You come especially then Importance when the bendable arm using the axis of rotation of the folding tape is held and to secure against rotation Measures are necessary.

Particularly low manufacturing costs result in very expediently in that the latching member by free end of the approach of the bendable arm is formed. The Locking element, the approach and the bendable arm are accordingly made in one piece, in particular from spring steel.

Another embodiment of the invention describes claim 6. In the case of a turn-tilt sash, it intervenes in a known manner pin attached to the free end of the scissor arm in a corresponding keyhole-like elongated hole of a cuff on upper wing end. In the tilted position Tilt position secured with the help of these scissors and also given.

Here is an advantageous development according to claim 7 expedient, which a corresponding alignment of Scissor arm opposite the rigid with the vertical holding arm connected guide arm within certain limits allowed.

The leaves of windows and doors usually have one rectangular form. There are also deviations from this, especially if a window is mounted near a roof becomes. The sloping roof may also have to be used be taken into account, i.e. the upper wing cross member runs parallel to the slope of the roof and not more parallel to the lower cross spar. With the help of special training according to claim 8 are also such Window with an upper pivot bearing of the type according to the invention equip.

The bearing element of Figures 1 and 5 is, so to speak a half of an upper pivot bearing of a rotatable or a rotating and tilting wing of a window, a door or the like, with this wing in addition to a lower opening-side bearing is mounted. In the event of the lower wing can only be rotated Wing bearings can be a simple pivot bearing. At a The tilt and turn sash must definitely be one of these Act a corner bearing that enables movement. On firm Frame against which the wing is at least rotatable is stored, there is a bearing block, which is fixed there is mounted. It has at least one bearing sleeve, which in the space between the two bearing sleeves 1 and 2 engages the bearing element according to the invention. In addition can still two more bearing sleeves on this bearing block be provided, the one above the Bearing sleeve 1 and the other below the bearing sleeve 2 located. All bearing sleeves are supported by a bearing pin interspersed, the longitudinal axis of which is also the geometric one Defined axis of rotation of the wing.

The two bearing sleeves 1 and 2 are in one Mounting position vertical, in the embodiment according to opposite directions angled folding tape 3, with which they are preferably made in one piece.

The folding tape 3 is around the geometric axis 4 on one vertical support arm 5 of the bearing element rotatably mounted. When shipping, it takes the middle shown in Figure 1 Rotational position. From there it can be in the direction of arrow 6 or rotated in the opposite direction to either one of them To take rotary end positions, which then also the Use position for this bearing element. The axis of rotation can be formed by a rivet 7. The vertical Holding arm 5 is in both embodiments with a sleeve-like guide arm 8 connected, so that a total angular element is created. In the embodiment 1, the holding arm 5 and the guide arm 8th made in one piece. In contrast, these two are Elements in the second variant (Figure 5) over a Swivel 9 connected to each other so that the guide arm 8th in the sense of the double arrow 10 compared to the vertical Holding arm 5 pivoted, i.e. on the course of the assigned frame spar can be set. In Figure 4 is the vertical axis of rotation of the upper pivot bearing of the wing shown against its fixed frame or the like with the reference number 11.

The guide arm 8 only forms with one in FIG schematically indicated element 13 together a upper cross member of a wing and thus of the fixed Frame assignable arm 12. In the case of a pure Swivel wing, this arm 12 is fixed to the upper one Wing cross member connected. However, if it is one Turn-tilt wing, the arm 12 is a so-called Scissor arm. The element 13 then forms the longer one Part of the scissor arm and this is preferably around Geometric axis 14 rotatable in the sense of the double arrow 15 mounted on the guide arm 8. For this reason, the Guide arm tubular in all variants. So you can then use the bearing element very universally.

According to the inventive design of this bearing element are located on the folding tape 3, each at the same distance from the axis of rotation 4 or the rivet 7, two locking recesses or preferably two openings 16 and 17. In each of the two rotational end positions of the folding tape 3 intervenes Locking member 18 in the associated opening 16 or 17th a. 4 is the latching element 18 in the assigned at this rotational position of the folding tape 3 Breakthrough 17 spring-loaded. Because that Locking member 18 according to Figure 3 on the level 19 of vertical holding arm 5 protrudes, you reach the snap or the previously necessary pushing back of the locking member 18 with the help of each breakthrough 16 or 17 assigned entry slope 20 (Figure 1).

The locking member 18 is according to the figure 3 on a resiliently bendable arm 21 with which it is preferably made in one piece. Its from The end of the latching member is on the vertical holding arm 5 held. In the embodiment is particular provided that the rivet 7 also has a bore on passes through the associated end of the bendable arm 21. opposite the latching member 18 projects over an arcuate extension 22 the plane of the bendable arm 21. According to FIG. 3, it engages in a receptacle 23 of the vertical holding arm 5, wherein it is preferably a breakthrough. Therefore form the approach 22 and the receptacle 23 one Anti-rotation device for the bendable arm 21 about the axis of rotation or the rivet 7. At the same time there is also a swivel guide educated. From Figure 3 it can be seen that the locking member 21 connects directly to the approach 22 and both are made together in one piece with the bendable arm 21, spring steel is the preferred material, how to use it on leaf springs. If you have the non-rotatable connection between the folding tape 3 and the vertical arm 5 wants to solve, so you can with the help a tool, for example a screwdriver, in Direction of arrow 24 through the opening 16 and 17 respectively act on the latch member 18 and this so far swing back that the locking between the Locking member 18 and the opening 16 and 17 is released. Then the folding tape 3 can then, for example from the use position shown in Figure 2 in a Turn back the ineffective position according to FIG. 1 or into the transfer the second effective rotational position.

In the embodiment of Figure 5 is instead of the two arranged in the longitudinal distance bearing sleeves 1 and 2 a continuous long bearing sleeve 1 provided, but it can can also be two bearing sleeves according to FIG. 2. In any Case intervenes with only one bearing sleeve 1 two bearing sleeves of the mentioned bearing block on the fixed frame. Otherwise, the axis of rotation of the swivel joint is 25 designated. Otherwise, the two variants can be the same be trained.

The locking of the folding tape 3 with the vertical holding arm 5 takes place in the manner described above by means of Locking member 18 and one of the two openings 16 or 17, wherein the locking member is resilient in each assigned breakthrough occurs.
