Abstract

In order to be able to use a bearing element of an upper pivot bearing for an at least pivotable or for a pivotable and tiltable sash/leaf of a window, of a door or the like, for right-hand attachment and for left-hand attachment of the sash/leaf, the rebate band (3) thereof is mounted, such that it can pivot about a geometrical axis (4), on the vertical retaining arm (5) of the bearing element and, with respect to the latter, can assume two operating positions which are offset through 180@. These are secured, according to the invention, with the aid of a latching device which comprises in each case one through-passage (16 or 17) and a latching member (18) which is retained, such that it can be deflected resiliently, on the vertical retaining arm (5), but, in particular, on the pivot pin (7). <IMAGE>

Description

The invention relates to a bearing element of an upper pivot bearing with an arm extending transversely to the geometric bearing axis, an upper cross member of an at least rotatably mounted on a fixed frame wing, a window, a door or the like assignable arm and at least one bearing sleeve for the wing pivot bearing, wherein the at least one bearing sleeve is located on a folding tape or the like, which is rotatably mounted about a horizontal axis on a vertical holding arm in the mounting position and can optionally be locked in one of two rotational positions offset by 180 °. Such upper pivot bearings are in connection with rotating blades or tilt and turn blades known from windows, doors and the like. The wings are hinged on either the left or right. However, one and the same pivot bearing should be usable for the two types of stop. As a result, this upper pivot bearing must be convertible so that it can be adjusted depending on the type of stop of the wing, which is done by rotating the folding band relative to the vertical holding arm of this upper pivot bearing. After reaching the rotary end position, the latter must be secured accordingly. In a previously known upper pivot bearing of the type described above, this is achieved in that the folding band is displaced upwards with respect to the vertical holding arm by means of an eccentric, wherein a twist approach of the folding band engages in a corresponding receptacle of the vertical holding arm. The eccentric is actuated using a suitable tool, preferably a so-called hexagon key, which is inserted into an internal hexagon of the eccentric. When shipping, the folding tape is normally in a neutral intermediate layer from which it only has to be turned 90 ° to the left or to the right, depending on whether the sash is hinged on the left or right.

It is now the task of developing a generic upper pivot bearing so that the adjustment to the left stop or right stop can be carried out without tools and the setting is nevertheless secured against rotation.

To achieve this object, it is proposed according to the invention that the upper pivot bearing is designed in accordance with the preamble of claim 1 in accordance with the characterizing part of this claim. With this upper swivel bearing, the folding tape is also in a neutral, rotating intermediate layer during shipping. The window manufacturer only has to check whether the sash should be hinged on the right or left and accordingly turn the folding tape into one of the two possible rotary end positions. Starting from the shipping neutral position, a 90 ° turn is sufficient. In the rotational end position, the folding tape is automatically locked with respect to the vertical holding arm, in that the locking member, due to its spring load, enters the then assigned locking recess or the like. The spring force must be selected so that the locking element cannot emerge again when the wing is operated normally. On the other hand, if a possibility is provided for this, the latching can be released by acting on the latching member counter to the latching direction and, especially if the folding tape has been accidentally rotated in the wrong direction before assembly, this error can be corrected again.

The locking member is advantageously located on a resiliently bendable arm. This must be held with respect to the vertical arm so that it can only perform the intended bending movement. In this respect, a further development of the invention provides that the locking member is integrally formed on the free end of the resiliently bendable arm, the end of which is remote from the latching element is held on the vertical holding arm. The held end of the bendable arm is held in a particularly expedient manner by means of the axis of rotation of the folding tape. As a result, the axis of rotation can then be used in two ways, which benefits the compact design and the inexpensive production.

A particularly preferred embodiment of the invention results from claim 5. It is particularly important when the bendable arm is held with the help of the axis of rotation of the folding tape and further measures are necessary to prevent rotation.

Particularly low manufacturing costs result in a very convenient manner in that the latching member is formed by the free end of the extension of the bendable arm. The locking member, the approach and the bendable arm are therefore in one piece, in particular made of spring steel.

A further embodiment of the invention is described in claim 7. In the case of a turn-tilt wing, a pin attached to the free end of the scissor arm engages in a corresponding keyhole-like elongated hole of a cuff at the upper wing end in a known manner. In the tilted position, the tilt position is secured with the help of these scissors and also specified.

Here, an advantageous development according to claim 8 is expedient, which allows a corresponding alignment of the scissor arm with respect to the guide arm rigidly connected to the vertical cold arm within certain limits.

The leaves of windows and doors usually have a rectangular shape. There are also deviations from this, especially if a window is installed near a roof. The sloping roof may then also have to be taken into account, i.e. the upper wing cross member runs parallel to the inclination of the roof and no longer parallel to the lower wing cross member. With the special training according to claim 9, such windows can also be equipped with an upper pivot bearing of the type according to the invention.

The bearing element of FIGS. 1 and 5 is, as it were, one half of an upper pivot bearing of a rotatable or a rotatable and tiltable wing of a window, a door or the like, this wing additionally being mounted on a lower opening-side bearing. In the case of a wing that can only be rotated, the lower wing bearing can be a simple pivot bearing. A tilt and turn sash must in any case be a corner bearing that enables these movements. On the fixed frame, against which the wing is at least rotatably mounted, there is a bearing block, which is fixedly mounted there. It has at least one bearing sleeve which engages in the space between the two bearing sleeves 1 and 2 of the bearing element according to the invention. In addition, two further bearing sleeves can be provided on this bearing block, the one above the bearing sleeve 1 and the other below the bearing sleeve 2. All bearing sleeves are supported by a bearing pin interspersed, the longitudinal axis of which also defines the geometric axis of rotation of the wing.

The two bearing sleeves 1 and 2 are located on a folding tape 3, which is vertical in the assembly position and angled in opposite directions in the exemplary embodiment, with which they are preferably produced in one piece.

The folding tape 3 is rotatably mounted about the geometric axis 4 on a vertical holding arm 5 of the bearing element. When dispatched, it assumes the central rotational position shown in FIG. From this it can be turned in the direction of arrow 6 or in the opposite direction to assume one of its two rotational end positions, which is then also the position of use for this bearing element. The axis of rotation can be formed by a rivet 7. The vertical holding arm 5 is connected in both embodiments to a sleeve-like guide arm 8, so that an angular element is formed overall. In the embodiment of Figure 1, the holding arm 5 and the guide arm 8 are made in one piece. In contrast, these two elements in the second variant (FIG. 5) are connected to one another via a swivel joint 9, so that the guide arm 8 can be pivoted in the direction of the double arrow 10 relative to the vertical holding arm 5, ie it can be adjusted to the course of the associated frame spar. In Figure 4, the vertical axis of rotation of the upper pivot bearing is not wing shown against its fixed frame or the like with the reference numeral 11.

The guide arm 8 forms, together with an element 13, which is only indicated schematically in FIG. 4, together an arm 12 which can be assigned to an upper cross member of a wing and thus also to the fixed frame. In the case of a pure rotating wing, this arm 12 is firmly connected to the upper wing cross member. However, if it is a turn-tilt wing, the arm 12 is a so-called scissor arm. The element 13 then forms the longer part of the scissor arm and this is preferably mounted on the guide arm 8 such that it can be rotated about the geometric axis 14 in the sense of the double arrow 15. For this reason, the guide arm is tubular in all variants. This allows the bearing element to be used very universally.

According to the design of this bearing element according to the invention, two locking recesses or preferably two openings 16 and 17 are located on the folding strip 3, each at the same distance from its axis of rotation 4 or the rivet 7. In each of the two rotational end positions of the folding strip 3, a locking member 18 engages in the assigned breakthrough 16 or 17. In the illustration according to FIG. 4, the latching element 18 has spring-loaded into the opening 17 associated with this rotational position of the folding tape 3. Because the latching member 18 protrudes beyond the plane 19 of the vertical holding arm 5 according to FIG. 3, the latching is achieved or the previously necessary pushing back of the latching member 18 with the aid of an inlet slope 20 assigned to each opening 16 or 17 (FIG. 1).

According to FIG. 3, for example, the latching member 18 is located on a resiliently bendable arm 21 with which it is preferably made in one piece. Its end remote from the latching element is held on the vertical holding arm 5. In the embodiment, it is provided in particular that the rivet 7 also penetrates a bore at the associated end of the bendable arm 21. Contrary to the latching member 18, an arcuate extension 22 projects beyond the plane of the bendable arm 21. According to FIG. 3, it engages in a receptacle 23 of the vertical holding arm 5, which is preferably an opening. Accordingly, the projection 22 and the receptacle 23 form a rotation lock for the bendable arm 21 about the axis of rotation or the rivet 7. At the same time, a pivoting guide is also formed. From Figure 3 it can be seen that the locking member 21 directly adjoins the extension 22 and both are made together in one piece with the bendable arm 21, the material preferably being spring steel as used in leaf springs. If you want to loosen the non-rotatable connection between the folding tape 3 and the vertical holding arm 5, you can use a tool, for example a screwdriver, in the direction of arrow 24 through the opening 16 and 17 to act on the latching member 18 and so far swing back that the locking between the locking member 18 and the opening 16 and 17 is released. The folding tape 3 can then be turned back, for example, from the position of use shown in FIG. 2 to an ineffective position as shown in FIG. 1 or transferred to the second effective rotational position.

In the exemplary embodiment in FIG. 5, a continuous long bearing sleeve 1 is provided instead of the two longitudinally spaced bearing sleeves 1 and 2, but there may also be two bearing sleeves according to FIG. 2. In any case, only one bearing sleeve 1 engages between two bearing sleeves of the mentioned bearing block on the fixed frame. Otherwise, the axis of rotation of the swivel joint is designated 25. Otherwise, the two variants can have the same design.

The folding band 3 is locked with the vertical holding arm 5 in the manner described above by means of the locking element 18 and one of the two openings 16 or 17, the locking element spring-elastically entering the respectively assigned opening. Of course, the kinematically reversed variant is also conceivable, according to which there is a receptacle or an opening on the vertical holding arm and according to which the two openings 16 and 17 of the folding tape 3 are each replaced by a spring-loaded latching element 18 of the same or a different type. The Training according to the two variants of Figures 1 and 5 is preferred for cost reasons.
