Description

The invention relates to a bearing for the at least rotatable mounting of a wing, a window, a door or the like on a fixed frame or a second wing, according to the preamble of claim 1. Such a bearing is known from US-A-2 926 382 known. A scissor store of a turn-tilt fitting has become known from DE-U-88 05 504. Due to the special design of its base body is only an asymmetrical attachment of the mounting screws for this bearing part possible on the frame. In addition, in the case of a large and heavy wing, the two bearing eyes are heavily loaded. If the bearing pin breaks, the wing can fall in the worst case.

With the US-A-2,926,382 a bearing has become known in which on the one hand the bearing sleeves are open at the periphery, on the other hand the bearing pin has two flats over which the bearing sleeves are pushed. A backup cannot take place.

Starting from US-A-2 926 382, the object of the invention is to develop a bearing of the type described at the outset in such a way that the disadvantages described do not occur, with a high load capacity and security against a wing crash being important in the event of a bearing pin break.

To achieve this object it is proposed according to the invention that the bearing is designed according to the preamble of claim 1 in accordance with the characterizing part of this claim. By attaching a third bearing eye between the two outer bearing eyes, there is the possibility of mounting the mounting holes between two bearing eyes so that a symmetrical drilling pattern can be realized. In addition, the load capacity of this bearing part increases in that the weight can now be absorbed by three instead of two bearing eyes. Should there be a bearing pin break - which is certainly extremely rare - this does not have the serious consequence that the wing can fall, rather one can safely assume that at least one of the bearing pin parts between two adjacent bearing eyes is still full is functional and thus prevents the wing from coming loose in the area of this bearing.

A further development of the invention provides that there is a fastening attachment, in particular a fastening bolt, on the back of the base body, at least in the region of the outer bearing eyes, the longitudinal axis of which runs perpendicular to the axis of rotation of the bearing. These two attachment approaches, which can have a maximum possible distance based on the length or height of the base body, allow additional anchoring of the bearing part in the frame in question, so that the load on the bearing part not only by the fastening screws, but also the fastening bolts on the material of the Frame is transmitted. The large base, which is given by the two attachment lugs, in particular attachment bolts, reduces the backlash, which can lead to undesired movements of the sash relative to the fixed frame to a minimum. If one provides fastening bolts, this has the advantage that the receptacles for this are circular, that is to say can be drilled.

According to a further embodiment of the invention, there are two fastening bores for the base body between two adjacent bearing eyes, all four fastening bores advantageously being arranged symmetrically to a longitudinal center plane.

A particularly cost-effective production can expediently be achieved in that the base body is made in one piece with the three bearing eyes and the attachment lugs. It is in particular a die-cast part. Furthermore, it is particularly advantageous that the bearing part is formed symmetrically to an imaginary central transverse plane. It can therefore be used equally for left and right hinged wings.

According to a particularly preferred variant of the invention, a bearing part with a securing device for the inserted bearing pin is characterized in that the securing device is assigned to the third, central bearing eye. It is particularly the case that the securing device is integrated in the third bearing eye. This gives a very compact, particularly slim design of the bearing part. In addition, an improvement over the known prior art results from the fact that only a single securing device is required.

A further embodiment of this camp is evident from claim 7. The locking member mentioned there is initially in its inactive release position, so that the bearing pin can be easily inserted into the three bearing eyes. When it has reached its final displacement position, this is easily done, for example can be realized that one attaches a corresponding head to its upper end in the position of use, which then comes to rest on top of the upper bearing eye, one rotates the securing member with the aid of a suitable tool, for example a screwdriver, through the intended angle, which then causes the engages at least one locking lug in the annular groove and thereby prevents the bolt from being moved or pulled out of the bearing eyes.

A problem-free assembly of the securing member and overall extremely low costs for the securing device as a whole can be achieved on the basis of the development according to claim 8. The securing member is simply inserted into the radial bore, and it thus has the correct position in relation to the bearing pin in the direction of its axis of rotation, that the locking is ensured by a simple rotation. The securing member is prevented from falling out by the bearing bolt itself, so that special measures in this regard are not necessary. The securing element can also be held in the bearing eye by groove chips.

The invention further relates to a bearing with a fixed frame side bearing part according to at least one of claims 1 to 11, and this is advantageously characterized in that the wing-side bearing part has two bearing sleeves offset in the longitudinal direction of the bearing axis of rotation, each between the middle and an outer Engage the bearing eye of the bearing part on the fixed frame with a small amount of axial play. It is preferably a scissors-type bearing, that is to say an upper pivot bearing of a so-called tilt-and-turn sash of a window or a door. If a second wing occurs instead of the fixed frame, this bearing can serve as a connecting bearing between adjacent elements of a folding door or a folding window. It can be seen from the drawing that the two bearing sleeves can be attached to a suitable base body shaped in accordance with the task, preferably molded on.

A particularly preferred embodiment of the invention results from claim 13. The advantage of this embodiment lies above all in the fact that in a series production, the frame, in particular the fixed frame, can be drilled regardless of whether the fitting parts in question later a turn fitting or a turn -Tilt hardware and whether this fitting is intended for a wing hinged on the right or on the left. Of course, in the case of a turn-tilt fitting, the corresponding hole for the opening-side bearing parts must also be made, which enable the sash to be tilted about the lower horizontal transverse axis. The holes for the vertical axis are always the same. So far there is no differentiation between the fixed frames in a series production Right-hinged and left-hinged as well as between the rotating sash and the tilt-and-turn sash.

Further advantageous configurations result from the subclaims and the following description of an exemplary embodiment.

The bearing part shown in Figure 1 is preferably used as a fixed frame side bearing part, and together with the bearing part of Figure 2 it forms a bearing for an at least rotatable mounting of a wing on a fixed frame or on a second wing. The two bearing parts 1 and 2 are rotatably connected to one another by means of a bearing pin 3, which results from FIG. 3.

The first bearing part 1 of FIG. 1 essentially consists of a plate-shaped base body 4 in the exemplary embodiment with first bearing eye 5 and second bearing eye 6 attached to its upper and lower ends in the drawing. In between there is the third or middle bearing eye 7 according to the invention arranged exactly between the first and the second bearing eye in the exemplary embodiment, whereby a symmetry to an imaginary horizontal plane through the center of the third bearing eye 7 is created. In addition, the bearing can be formed symmetrically to an imaginary vertical plane through the middle of all three bearing eyes. Instead, the base body according to FIG. 1 can have a reinforced edge on one long side for reasons of stability. The bearing bores of the three bearing eyes are designated 8, 9 and 10. They run coaxially and are through holes. The geometric axis of the rotary bearing is defined by the geometric longitudinal axis of the bearing pin 3 or the central axes of the three bearing bores 8, 9 and 10.

It can also be seen from FIG. 1 that between two adjacent bearing eyes 5 and 7 on the one hand and 7 and 6 respectively on the other hand, two fastening bores 11 and 12 or 13 and 14 are provided, which are countersunk bores. At the upper and lower ends in FIG. 1 there is a preferably bolt-shaped attachment projection 15 or 16 on the base body 4. It extends opposite to the associated bearing eye 5 or 6 and engages in a bore of the frame corresponding to its cross section, on which the first Bearing part 1 is to be attached. The base body 4 is preferably embedded in the material of the frame in question. In order to be able to mill out the recess in a simple manner, the upper and lower ends 17 and 18 are semicircular.

The third or middle bearing eye 7 receives a securing device 19 for the bearing pin 3. The essential element of this securing device is the securing member 20 shown enlarged in FIGS. 4 to 6. It is rotatably mounted in a radial bore 21 of the third bearing eye 7. This bore is narrowed outwards in sections. The pin-shaped part 22 of the securing member 20, which is smaller in diameter and provided with a longitudinal slot, projects into the smaller bore part visible in FIG. 1. It can end approximately flush with the jacket of the third bearing eye 7. The securing member 20 is supported with its collar 23 on the shoulder, which arises from the transition from the narrowed part of the radial bore into the further part of the latter.

Opposed to the peg-shaped part 20, two locking projections 24 and 25 offset from the collar 23 project in the axial direction. They form a longitudinal groove 26 lying between them, which is circular in cross-section and extends perpendicular to the image plane in FIG. 4. Its radius corresponds to that of the bearing bolt 3 or more precisely its sections located on either side and beyond its annular groove 27. Accordingly, the bearing pin 3 can be moved along the longitudinal groove 26 with the corresponding rotational position of the securing member 20, without the displacement movement being impeded by the two locking projections 24 and 25. These are in the ineffective rotational position of the securing member outside the range of movement of the bearing pin 3. However, if the securing member 20, starting from the position shown in FIG. so engage the two locking lugs 24 and 25 in the annular groove 27 and thereby prevent, largely free of play, the displacement movement of the bearing pin 3 in the first bearing part 1. The rotation of the locking member 20 is achieved by means of a suitable tool, for example a screwdriver, which in the externally accessible slot 28 of the securing member 20 can be inserted.

The bearing pin 3 is conical at its insertion end in a known manner and has a plate-shaped head 29 at its opposite end is supported when the bearing pin 3 is fully inserted on the upper side of the first bearing eye 5 visible in FIG. 1. In this way, on the one hand, the insertion movement is ended and, on the other hand, the exact assignment of the annular groove 27 to the securing member 20 or its locking projections 24 and 25 is ensured. At the same time, of course, this head also forms a handle for pulling out and protection against falling out downwards, if or as long as the locking member has not yet been turned into the working position.

When the rotary bearing is assembled, the bearing sleeve 30 of the second bearing part 2 engages between the bearing eyes 5 and 7. The other bearing sleeve 31 consequently engages between the third bearing eye 7 and the second bearing eye 6. The lengths of the bearing sleeves 30 and 31 are selected so that they match the usual axial play fit exactly between the bearing eyes. In the exemplary embodiment in FIG. 2, the two bearing sleeves 30 and 31 are attached to an angular base body 32, in particular made in one piece. It has mounting holes in a known manner, which, however, cannot be seen in FIG. 2.
