The invention further relates to an adjustment device of the aforementioned type.

25 ROTO FRANK AG, 70771 Leinfelden-Echterdingen, Germany, offers a hardware arrangement in the form of a corner bearing with the designation "Roto NT Designo®". The already known corner bearing is part of hidden hardware, through which window or door sheets are attached to corresponding fixed frames. The fittings allow a

30 turning movement and a tilting movement of the sheet in question in relation to the fixed frame where it is housed. The corner bearing comprises an angle of attachment, which is inserted on the side of the revalve into a corner of the fixed frame and bolted to it. On the side of the angle of fixation opposite a horizontal surface of the fixed frame is an extension compass of the corner bearing, which in turn has two compass rods. These are placed one above the other in a perpendicular position with respect to the horizontal surface of the fixed frame and intervene, with their free ends away from the fixing angle, on the sheet to be supported. The leaf is guided in the extensor compass

5 its movement in relation to the fixed frame. The load of the leaf is transmitted by the connecting rods to the fixed frame. To this end, the already known corner bearing is provided, in addition to the fasteners between the fixing angle and the fixed frame, of a bearing projection that intervenes vertically in the fixed frame from the renewal side of said fixed frame .

In WO 01/44610 A1 another current state of the art is described. This publication refers to hardware for housing a window, door or similar sheet in a vertical stringer of a fixed frame. The subassemblies of the hardware are distributed at the top of the frame of the frame in question. A band of each subset is fixed to the frame stringer by means of bushings

15 spacers oriented horizontally and by means of fixing screws screwed into the spacers and also extending horizontally. The distance bushings are in turn fixed to a seat plate and at the same time are moved backwards, towards the inside of the seat plate, with respect to the edges of the seat plate

20 extending parallel to the frame stringer. In the assembled state, the seat plate rests on the side that is away from the renewal side of the frame stringer and at the same time on ribs of the frame stringer profile provided therein.

From US 3,145,414 A is known a current state of the art of this

25 type This publication describes a reciprocating door with a rotating bearing on the floor side. The rotating bearing cooperates on the one hand with a stump in the door leaf to be supported and, on the other hand, with a threaded bolt on a door threshold. On the side of the door threshold opposite the stump, on the threaded bolt, there is a stepped nut in the axial direction of the threaded bolt. With a

30 axial section of reduced diameter, the nut intervenes in the opening of the door threshold that is crossed by the threaded bolt. An axial section of the radially enlarged nut rests on the lower side of the door threshold and is housed therein which, by virtue of the vaulted form of the door threshold, is configured between it and the floor which supports the threshold of

35 door The enlarged axial section of the nut protrudes in the radial direction of the threaded bolt on all sides in relation to its axial section of reduced diameter.

The aim of the present invention is to provide an easy-to-fit adjustment device by which heavy sheets, in particular sheets weighing 130 kilograms and more, can also be housed in a corresponding fixed frame, as well as providing a corresponding window, a door

5 corresponding or similar.

According to the invention, this objective is achieved by means of the adjustment device according to claim 1 and by the window, the door or the like according to claim 2.

The bearing projection of the adjusting device according to the claim is propped up.

10 using a counter bearing. The counter-bearing comprises a counter-bearing base and a counter-bearing projection provided therein. The latter intervenes in the fixed frame in the opposite direction to the bearing projection and props the bearing projection against a slope in the transverse direction of the main plane of the window, door or the like. Thanks to the use of the counter bearing,

15, the fixing device makes it possible to support also heavy-weight sheets in the fixed frame, in particular sheets of 130 kilograms and more, without having to fear deformations and / or unwanted damage to the window, the door or the like in question . The counter bearing provides the fixed frame with a reinforcement, which is especially useful when the fixed frame itself has a limited load capacity.

In particular, fixed frames made of wood or with hollow profiles, for example with hollow plastic or metal profiles, especially hollow aluminum profiles, can also be reinforced correspondingly. The reciprocal displacement provided in the case of the invention of the counter-bearing projection and the counter-bearing base allows the counter-bearing base to be arranged on the side

25 opposite of the fixed frame that is away from the side of its revamp at a greater distance from the delimitation of the opening side of the fixed frame than the counter-bearing projection housed inside the fixed frame. These features of the invention are especially important when the fixed frame is provided with one or more frame projections on the opposite side of the frame.

30 fixed that is away from the side of revalidation and, in the same, near the opening side of the fixed frame. Such frame projections would prevent the mounting of the counter-bearing base near the opening side of the fixed frame and, therefore, would have to be removed, at least in part, before mounting the counter-bearing according to the invention. This additional assembly step is avoided if, as planned according to

In accordance with the invention, the counter-bearing base can be arranged at a sufficient distance from the opening side of the fixed frame and with it next to the said projections of the fixed frame. The frame projections of the type described are provided primarily for fixed window frames and plastic doors. Particularly advantageous is the fact that the counter bearings according to the invention can be used in combination with the hardware arrangements of the current state of the art described above. Accordingly, arrangements according to the invention can also be obtained by only subsequently equipping already known arrangements.

From dependent claims 3 to 8, special embodiments of the devices described in independent claims 1 and

2.

From claims 3 to 5, features can be concluded which, in a preferred configuration of the invention, allow a simple construction from the construction point of view and thus economical of the fittings.

The realization of the counter-bearing base as a counter-bearing seat plate (claim 4) is especially recommended in view of the conditions of the reduced mounting space in the fixed frame of windows, doors or the like according to the invention.

The connection between the counter-bearing base and the counter-bearing projection of the counter-bearing according to the invention can be carried out in multiple ways (claim 5).

Claims 6 and 7 refer to applications of the invention especially relevant for practice.

According to claim 6, the fixing device according to the invention is a concealed device with at least two connecting rods that, being the closed leaf, are housed in a revalidation between the leaf and the fixed frame, so that they are not visible from the outside. At least one of the connecting rods is housed in the fixed frame by means of the bearing boss that interacts in the fixed frame from the side of the same. In the case of hardware arrangements of this type, the weight of the blade to be transmitted to the fixed frame has a relatively long force arm, especially with the blade open. Correspondingly large is the load that, through the arrangement of hardware, is applied to the fixed frame. The counter bearing according to the invention guarantees, especially in the case of heavy weight blades, a functionally safe load absorption, without deformation and / or unwanted damage, in particular in the fixed frame.

image5

According to claim 7, the concept according to the invention is applied in a fixed frame configured as a hollow profile frame and, therefore, in a type of frame that originally has only a limited load absorption capacity.

According to claim 8, in another preferred configuration of the invention, the

5 inside the fixed frame is sealed from the outside in the counter bearing area. In this way, the penetration of moisture or dirt into the fixed frame and, from it, into the enclosure provided with the window, the door or the like in question can be prevented in particular. As gaskets, for example, o-rings, flat gaskets and extruded silicone gaskets are considered.

The invention is explained in more detail below by means of the figures, which by way of example show:

Figure 1: Design of the principles of a lower corner area on the side of the band of a plastic window, Figure 2: Partial representation of the arrangement according to Figure 1, in the sectional plane II of Figure 1 ,

Figure 3: representation in partial section of the arrangement of Figures 1 and 2, in the section plane III-III of Figure 2,

Figures 4a, 4b, 4c: three representations of a first form of

20 construction of the counter bearing of a fixing device according to the invention for the plastic window of Figures 1 to 3 and

Figures 5a, 5b, 5c: three representations of a second form of construction of the counter bearing of a fixing device according to the invention for the plastic window

of Figures 1 to 3.

Referring to Figure 1, a plastic window 1 has, as usual, a sheet 2 and a fixed frame 3. By means of hidden hardware and therefore not visible when the sheet 2 is closed, the sheet 2 is housed in the fixed frame 3 so that it can rotate around a vertical pivot axis and swing around a horizontal tilting axis. Part of the concealed fittings is an arrangement of fittings in the form of a corner bearing 4, of which a counter-bearing base 5 of a counter-bearing 6 can be seen in Figure 1. By means of the counter-bearing 6 the fundamental design and operation are described fundamental of a

35 counter-bearing of this type. Counter bearings 6/1, 6/2 according to the invention are shown in Figures 4a to 5c.

image6

Figures 2 and 3 show other details of the corner bearing 4.

According to Figure 2, the corner bearing 4 comprises a corner bearing angle 7, which is inserted in a revalve side 8 of the fixed frame 3, in a corner of the fixed frame 3. On a horizontal side of angle 9 and on one side

5 vertical angle 10, the corner bearing angle 7 is screwed to a horizontal crossbar 11 and to a vertical crossbar 12 of the fixed frame 3. Additionally, positioning projections 13 of the corner bearing angle 7 fit into corresponding housings of the fixed frame 3.

Next to the top of the horizontal side 9 of the corner bearing angle 7

10, an extension bar 14, made as an X compass, of the corner bearing 4 is provided. The extension bar 14 comprises, as is known, two connecting rods 15, 16 angled in opposite directions, which, when the leaf 2 is closed, is they find one on top of another in a rebate 17 (Figure 3) between sheet 2 and the fixed frame 3. In the opening and closing movements of sheet 2 in relation to the frame

15 fixed 3, the extension bar 14 guides the leaf 2 in relation to the fixed frame 3 perpendicular to the main plane of the window 1. The connecting rods 15, 16 are articulated on the one hand on the leaf 2 and on the other hand in the angle 7 of corner bearing 4.

The sheet 2 shown by way of example has a weight of 130 kilograms. The weight

20 of the blade is transmitted to the angle 7 of the corner bearing 4 by means of the extension compass 14. From the corner bearing angle 7, the load acting on it must be transmitted to the fixed frame 3 of the window 1. This function is performed on the one hand the screws provided between the corner bearing angle 7 and the fixed frame 3. Furthermore, on the bottom of the horizontal side 9 of the bearing angle of

25 corner 7, the corner bearing 4 has a bearing projection 18 which has a projection 19 of the counter bearing 6 assigned. The bearing projection 18 is a circular cylindrical stump 20 and a stump bush 21 placed with an exact fit on the stump 20. The stump 20 is provided on the connecting rod 16 of the extension compass 14, and the stump bush 21 is provided on the horizontal side 9 of the

30 corner bearing angle 7. The bearing projection 18 sinks into the horizontal crossbar 11 of the fixed frame 3, in the vertical direction of the projection, from the renewal side 8 of the fixed frame 3.

In the opposite vertical direction, the protrusion 19 of the counter bearing 6 cooperates with the horizontal crossbar 11 of the fixed frame 3 from an opposite side of the fixed frame 22, 35 opposite to the revamp side 8 of the fixed frame 3. In the example shown, the projection of counter-bearing 19 forms a concentric counter-bearing bushing to the projection

image7

of bearing 18. In the vertical direction, the counter-bearing boss 19 is overlapped with the bearing boss 18 along its entire axial length. In addition, the counter-bearing projection 19 encloses the bearing projection 18 with an exact adjustment and, consequently, with a radial play at the most minimum.

At its longitudinal end assigned to the opposite side of the fixed frame 22, the counter-bearing projection 19 is fixed to the base 5 of the counter-bearing 6, which protrudes laterally in relation to the counter-bearing projection 19. For this purpose, the counter-bearing projection as a of bushing 19 is inserted with its axial end in question in a blind bore correspondingly sized from the counter-bearing base 5 and welded to the counter-bearing base 5. In the example shown, the counter-bearing base 5 is made as a seat plate of counter-bearing and bolted to the horizontal crossbar 11 of the fixed frame 3 at a certain radial distance from the counter-bearing boss 19. Overall, the counter-bearing 6 is angled.

The fixed frame 3 is configured as a hollow plastic profile frame and, as such, has several hollow chambers inside. In a hollow chamber 23 of the fixed frame 3 a reinforcement profile 24 is inserted in the usual way (Figure 3). In the reinforcement profile 24, three of the total five fixing screws for the counter bearing 6 are involved. The other two fixing screws for the counter bearing 6 are screwed into the plastic material of the fixed frame 3.

The projection 19 of the counter bearing 6, with the bearing projection 18 housed therein, is located inside a bore 25, which has been created in the fixed frame 3 near the visible surface of the fixed frame 3 facing a opening side 26 of the fixed frame 3. The opening side 26 is about the side of the fixed frame 3 in which the sheet 2 can move relative to the fixed frame 3. A seal configured as an O-ring 27 is placed on the projection of counter-bearing 19 and seals, inside the fixed frame 3, relative to the outside, the hole 25 which serves to house the counter-bearing projection 19.

As can be seen from Figures 1 and 3, the fixed frame 3 is provided, for example on the opposite side of the fixed frame 22, with projecting moldings 28. To mount the corner bearing 4, the moldings 28 must be removed in the area where the base 5 of the counter bearing 6 is found. The molding 28 located towards the opening side 26 of the fixed frame 3 can be left partially here near the counter bearing base 5.

image8

In the case of the invention, instead of the counter bearing 6 according to Figures 1 to 3, a counter bearing 6/1 (Figures 4a, 4b, 4c) or a counter bearing 6/2 (Figures 5a, 5b, 5c) is provided. Figures 4b and 5b are sectional representations, whose section planes are indicated in Figures 4a and 5a.

5 In the case of counter-bearing 6/1, a counter-bearing projection 19/1 as a counter-bearing bushing only in a part of its longitudinal extension has been made, unlike the projection 19/ of the counter-bearing 6. To produce the counter-bearing bush, a central bore is made in a part of the axial length of a circular cylindrical blank, composed of a

10 solid material, for counter-bearing projection 19/1. At its end facing the counter-bearing base 5/1, in the blank, for the counter-bearing boss 19/1, an eccentric fixing pin 30 with a non-circular cross-section is formed. With the fixing pin 30, the counter-bearing boss 19/1 fits into a corresponding passage opening 31 in the

15 counter-bearing base 5/1. In cooperation, the fixing pin 30 and the passage opening 31 ensure the counter-bearing projection 19/1 being dragged against an unwanted turning movement in relation to the counter-bearing base 5/1. In addition, the counter-bearing boss 19/1 and the counter-bearing base 5/1 are welded together in the fixing pin 30.

20 A passage opening 31 is arranged in the counter bearing base 5/1 so that, with the counter bearing 6/1 mounted, there is a reciprocal lateral displacement between the counter bearing boss 19/1 and the counter bearing base 5/1 (Figure 4c). If the counter bearing 6/1 is used instead of the counter bearing 6 to accommodate the projection 18 of the corner bearing 4, the molding 28 located to the side

Opening 25 of the fixed frame 3 - unlike the conditions according to Figure 3

- it can remain complete in the fixed frame 3. This simplifies the mounting of the corner bearing 4.

The use of the 6/2 counter bearing of Figures 5a, 5b, 5c implies a corresponding advantage. Unlike the 6/1 counter bearing, in the case of the counter bearing

30 6/2 a counter-bearing projection 19/2 is riveted to a counter-bearing base 5/2 in a rivet stump 32. Otherwise, the counter-bearings 6/1 and 6/2 have the same design.

Regardless of the design used for the counter bearing, the corner bearing 4 guarantees a functionally safe transmission of the weight of the blade 2 35 to the fixed frame 3. Especially with the blade 2 open, the weight of the blade acts on the fixed frame 3 by means of the extensor compass 14 with a relatively long force arm. Accordingly, the blade 2 tends to tip the projection 18 of the corner bearing 4 in the direction of the opening side 26 of the fixed frame 3 with its end located towards the renewal side 8 of the fixed frame 3. The counter bearing 6, 6/1 , 6/2 counteracts such a tilting movement and deformations and / or 5 the damages resulting therefrom in the fixed frame 3 and / or in the corner bearing 4,

image9

or in other hardware pieces provided between sheet 2 and fixed frame 3; it houses the bearing projection 18 against a tilting movement in the direction of the opening side 26 of the fixed frame 3. The shoring of the counter-bearing base 5, 5/1, 5/2 on the opposite side of 10 is of essential importance here fixed frame 22 made as a screw in the example shown. By means of this shoring or this screwing, the counter-bearing base 5, 5/1, 5/2, and with it the end of the counter-bearing projection 19, 19/1, 19/2 assigned to it, is prevented from moving under the load in the opposite direction to the opening side 26 of the fixed frame 3. To reinforce the shoring effect of the

15 counter-bearing 6, 6/1, 6/2, the fixed frame 3 can be filled with an additional material around the counter-bearing 6, 6/1, 6/2, for example loaded with a suitably strong hardening foam.
