Description

The invention relates to a bearing for doors, windows or the like. With a first and a second bearing part and a control tab, which is pivotally connected to a bearing part, and along a guide limited relative to the other bearing part is movable.

For concealed fittings of windows, doors or the like, with and without rollover, the sash weight must be absorbed by the concealed fitting. Furthermore, in particular in the case of windows, doors or the like with rollover, the wing must first be opened for opening from the fixed frame so that there is no collision between the rollover and the frame when the wing is opened. For the concealed fitting only a limited installation space is available. In this narrow installation space, a scissors geometry must be provided so that a parking of the wing is even possible.

From the DE 3516 560 U1 For example, an opening device for wings of windows, doors or the like has become known, wherein the opening device has a short arm, which has at its ends in each case a joint and has a long arm, which also has joints at its ends. The short link communicates with the fixed frame via a hinge while engaging the wing with a second link. The long handlebar is in turn articulated by a hinge on the fixed frame, while he attacks on his other joint on the wing. Each one joint of the long and short handlebar are with connected to the fixed frame by screws to be fastened bearing rail, which is fixed parallel to the plane of the fixed frame at its Falzumfangsfläche. The respective other joints of the short and long arm engage with a retaining rail, which is also connected to the wing, also parallel to its plane, connected to the Falzumfangsfläche. Some joints are designed as pure hinges, while others are designed as a spur - tilt bearings.

There are other scissor geometries known which have fewer components, wherein a control tab is slidably disposed with respect to a bearing part at least one end.

Object of the present invention is to develop a bearing such that it can be made small on a small building and can accommodate the other wing loads with a small size.

This object is achieved by a bearing of the aforementioned, in which the guide is arc-shaped. By this measure, it is possible to build the camp as a whole smaller and more stable. In particular, this makes it possible to realize a very small pair of scissors. Preferably, the guide is bent in the direction of the other bearing part. Particularly preferred is an embodiment in which
the guide is circular segment-shaped. The bearing can be designed as a so-called Axerlager or corner bearing. An axle bearing serves to connect the frame and sash in an upper area and the corner bearing serves to connect the frame and the sash in a lower area of the frame. In particular, in an embodiment as a corner bearing, the first and second bearing part can be arranged pivotally to each other.

In a preferred embodiment of the invention, the guide is designed as a gate in which a rotatably connected to the control tab slider is guided at least with a section. A backdrop is a particularly simple embodiment of a guide. It may be formed in particular as a cutout or punched in a bearing part. The fact that the slider is rotatably mounted on the control tab, this is constantly properly oriented in the backdrop during the opening or opening movement. In addition, this makes it possible that the control flap with respect to the second bearing part performs a pivoting movement.

In a particularly preferred embodiment, it can be provided that, during operation, at least one lateral contact surface of the slider abuts flat against an inner wall of the slide. If a force acting transversely to the frame main plane, for example due to a heavy wing or a small size of the bearing, which acts on the control tab by the scissors, too large, it is advantageous if the slider rests not only punctiform or linear on the backdrop, such as This would be the case, for example, in a circular slider, but rests flat. As a result, the wear can be significantly reduced.

It is particularly preferred if the slider has two parallel abutment surfaces, which abut against inner walls of the link. As a result, the slider has two parallel contact surfaces, which rest in the curved backdrop. For this purpose, it is conceivable on the one hand to give the slider the same geometries as the scenery. This would mean that the contact surfaces of the slider from the outset have the same curvature as the inner walls of the backdrop. With a large radius of the scenery and a small circle section on the slider, however, the correct mounting position is difficult to see. If the slider does not match the scenery has curved contact surfaces, but initially has an elongated shape with substantially straight side surfaces is located at the beginning (immediately after installation), the slider on the curve (inner wall) with the larger radius initially only at two points and on the opposite side only at one Point on. The slider is loaded on a built-in at the upper end of the frame bearing (Axerlager) on the contact surface to the large radius of the backdrop stronger. If the bearing is installed at the bottom (corner bearing), on the other hand, the opposite contact surface is more heavily loaded. The slider and the gate are advantageously designed so that the distance between the slider and gate is so small that the surfaces even after just a few movements to match in their forms and for the further operation of a planar system arises.

A planar system has the disadvantage over a linear system that a larger friction surface is available. Therefore, it is advantageous if the contact surfaces of the slider and the guide are tuned to minimize friction, in particular at least the material of the contact surface of the slider and the inner wall of the guide to minimize the sliding friction are matched. For example, the inner wall of the gate, or the entire bearing part, which has the backdrop may be formed of steel. The contact surface of the slider, or the entire slider, may be formed of bronze, brass, ceramic or sintered metal. It is understood that the contact surface of the slider is formed of steel and the inner wall of the slide can be formed from one of the other materials. Furthermore, the surfaces may be coated with Teflon.

The assembly of the slider is facilitated if the slider is formed symmetrically with respect to its central longitudinal plane. Thus, the fitter does not have to pay attention to his orientation.

It is advantageous if the ratio between length and width is chosen so that the slider can be installed in only two or four positions in the guide. The slider is automatically installed correctly. Costs and mix-ups can be significantly reduced. Misassembly and consequent rejects are excluded. The slider may for example be substantially rectangular, in particular square.

If the gate in cross-section is stepped or formed as an undercut groove, it can be ensured that the slider is not accidentally removed from the backdrop. Alternatively it can be provided that the slider has a projection with which it engages behind the Berandlung the backdrop. On the control tab, the slider may be attached via suitable fasteners, for example by riveting.

Preferably, the control tab on a Eckbandaufnahme, in particular a support pin on. This allows the weight of the wing to be transferred to the control tab. The control flap in turn rests on a support member designed as a bearing member and thus transmits the load on the support bracket. The scissors geometry is preferably chosen so that there is the greatest possible overlap of the control flap and the support flap. Thus, a resulting bending moment is kept low.

A compact construction of the bearing is made possible when a downwardly directed load-bearing device is provided. Such a load-bearing device is advantageous because it does not have to be accommodated in the seaming air area between the frame and the wing.

In a particularly preferred embodiment can be provided, a bearing part as a support tab and a bearing part as attachable to a frame Base plate is formed, wherein the base plate has at least a portion of the load receiving device. Preferably, the base plate has a downwardly directed sleeve in which a downwardly directed support pin of the support lug is rotatably arranged. By this arrangement, the support tab can initiate the resulting bending moment on the support pin in the sleeve. The support bracket is firmly connected to the support bolt. The sleeve, which is fixedly connected to the base plate, serves as an abutment to the occurring bending moment, which is introduced via the support bracket and the support bolt. The sleeve and the support bolt form a hinge. As a result, the pivotable connection of the first and second bearing part is realized. The distances between the support bolt, control tab and support pin significantly influence the resulting bending moment. Therefore, these are to be kept as small as possible in order to minimize the bending moment. The forces are transmitted to the base plate via the sleeve. This directs the forces on the screw in the frame. The forces in the base plate are influenced by the length of the sleeve and the support pin. These must therefore be selected accordingly for a sufficient load bearing.

The scope of the invention also includes a window, a door or the like, with a fixed frame and / or at least one wing, comprising at least one bearing described above.

Further features and advantages of the invention will become apparent from the following description of embodiments of the invention, with reference to the figures of the drawing, which show details essential to the invention, and from the claims. The individual features can be realized individually for themselves or for several in any combination in a variant of the invention.

In Fig. 1, the lower corner portion of a window is shown. A designed as a frame solid frame 1 is connected via a bearing 2 with a wing 3. The wing 3 has a rollover 4. In order to open the wing 3, therefore, the wing 3 must first be parked by the frame 1. This is made possible by the bearing 2.

The bearing 2 comprises a base plate designed as a first bearing part 5, with which a support member designed as a second bearing member 6 is pivotally connected. When using the bearing 2 as Axerlager the pivotal connection of the first bearing part 5 can be solved. A control tab 7 is pivotally connected to the second bearing part 6. The end 8 of the control plate 7 is displaceable along a guide 9 relative to the first bearing part 5. The control tab 7 and the bearing part 6 form a scissors geometry. In the exemplary embodiment, the scissors geometry is designed so that the wing 3 is turned off as little as possible and still creates the largest possible clear width. To open the wing 3, this is just as far from the frame 1, that there is no collision between the flashover 4 and the frame 1.

The first bearing part 5 is bolted to the frame 1. On the wing 3, a corner band 10 is provided, with which the wing 3 is supported on the control flap 7.

The illustration of FIG. 2 substantially corresponds to that of FIG. 1. Only the wing 3 is no longer shown. For this purpose, now connected to the control tab 7 supporting bolt 15 which forms a Eckbandaufnahme, visible on which the corner band 10 can be stored. The second bearing part 6 has at its free end also a pin 16 which engages from below into the wing 3, or a fitting part arranged thereon. The weight of the wing 3 is transmitted via the corner band 10 on the support pin 15. This transfers the weight then on the control tab 7. The control tab 7 rests on the second bearing part 6 and thus transmits the load on the second bearing part 6. The scissor geometry was chosen so that the greatest possible overlap of the control tab 7 and the second bearing part. 6 with the wing open 3 is present. Thus, a resulting bending moment is kept small.

From the representation of the bearing 2 in Fig. 3 it can be seen that the guide 9 is executed bent. In particular, the guide 9 is bent in the direction of the second bearing part 6. Through the ends of the guide 9, the movement of the control flap 7 is limited relative to the first bearing part 5. The first and second bearing part 5, 6 together form a load-receiving device 20. For this purpose, the first bearing part 5 a downwardly extending sleeve 21 into which a support pin 22 which is fixedly connected to one end of the second bearing part 6, protrudes. In this case, the second bearing part 6 initiates the bending moment arising under the weight of the flared wing via the support bolt 22 into the sleeve 21. The sleeve 21 serves as an abutment for the occurring bending moment, which is introduced via the second bearing part 6 and the support pin 22. The sleeve 21 and the support pin 22 form a hinge. The forces occurring are transmitted to the first bearing part 5 via the sleeve 21. This introduces the forces on the screw in the frame 1. Due to the fact that the load-receiving device 20 projects downwards, in particular into the frame, the bearing 2 occupies only a small amount of space in the rebate air area.

In the partial exploded view of Fig. 4, the support pin 22 is better seen, which is inserted into the sleeve 21. Furthermore, it can be seen in this illustration that the guide 9 is formed bent. About a closer to be described slider 30, the control tab 7 and the first bearing part 5 in the region of the guide 9 and the passage opening 25 are interconnected.

5 shows a view from below of the bearing 2. The guide 9 is formed as a backdrop whose boundary is made stepwise. A slider 30 is slidably disposed in the guide 9 and establishes the connection to the control tab 7 ago. For this purpose is as a fastener Gleiterniet 31 is provided which connects the slider 30 rotatably connected to the control tab 7. The fastening means, in particular the Gleiterniet, can be considered as part of the slider 30. Due to the rotatable connection, the slider 30 can align during a sliding movement in the guide 9. The guide 9 has an inner wall 32 with a smaller radius and an inner wall 33 with a larger radius. The slider 30 has two contact surfaces 34, 35 with the inner walls 32, 33 of the guide 9. The planar contact of the slider 30 on the inner walls 32, 33 results in a good absorption of laterally acting forces. In this case, the slider 30 rests on the steps 36, 37 at least with sections, so that it is prevented that this falls through the first bearing part 5 therethrough.

In Fig. 6a, a rear view of the slider 30 is shown. The contact surfaces 34, 35 are straight in the still unused state. Overall, the slider 30 has an elongated shape. It is formed symmetrically with respect to a central longitudinal plane 40. From FIGS. 6b, 6c, it can be seen that the slider 30 is also step-shaped. It is with the step 41 on the step 36 of the guide 9 and with the step 42 on the step 37 of the guide 9. Due to the step-shaped configuration, two contact surface sections 34.1, 34.2 or 35.1, 35.2 can each result on both sides. All surface sections 34.1, 34.2, 35.1, 35.2 can interact with corresponding inner wall sections of the guide 9. However, it is also conceivable that, for example, only the contact surface sections 34.1, 35.1 interact in a sliding manner with corresponding inner wall sections of the guide 9.
