Abstract

The fitting (2) has a part (5) with a guide (9) and a first bracket joined to a sliding part (25) that is guided in the guide with at least one lateral sliding surface, along which the sliding part slides when the bracket moves. The at least one lateral guide slide surface and a sliding part surface that slides along it during movement of the bracket are matched to each other so that the sliding part surface contacts different points pn the guide slide surface. An independent claim is also included for a window, door or similar with an inventive fitting.

Description

The invention relates to a fitting for a window, a door or the like. With a fitting part, which has a guide, and a first tab, which is connected to a slider which is guided in the guide, wherein the guide has at least one lateral Führungsgleitfläche along which the slider slides during a movement of the tab (see DE 20 2006 003 177 U1 and EP 1 612 356 A2 ).

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.

To stop the wing scissor geometries are known, wherein a tab with respect to a fitting part is slidably disposed at least one end. If such a scissor geometry to remove the load of the wing, the connection of the tab is subject to the fitting part of large forces.

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

This object is achieved by a fitting of the aforementioned, in which the at least one lateral Gleitgleitfläche and on the Führungsgleitfläche during movement of the tab along sliding Gleitstückfläche are coordinated such that the Gleitstückfläche in the movement along the Führungsgleitfläche with different locations, preferably always with another location, abuts the Führungsgleitfläche. By this measure, the resulting wear on the slider is distributed over a larger area, so that it does not fall into the weight. In contrast, a fully cylindrical slider would always have the nip at almost the same location, resulting in greater wear. Preferably, the contact surfaces are adapted to each other, that always takes place only a linear contact. However, this contact line moves with the movement of the tab relative to the fitting part along the Gleitstückfläche. Preferably, the fitting according to the invention is a concealed fitting.

The fitting 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 a particularly preferred embodiment it can be provided that the guide has two guide sliding surfaces and that the slider has two sliding surfaces, which are each tuned to a Führungsgleitfläche. By this measure, the slider is guided on two opposite surfaces. This increases the stability of the fitting.

An embodiment is characterized in that the slider is rotatably connected to the first tab. By this measure, it can be ensured that the contact line of the slider moves on the guide sliding surfaces during the relative movement of the tab to the fitting part. As a result, the wear can be minimized.

A particularly compact embodiment of the fitting results when the guide is formed bent and / or is aligned obliquely to a longitudinal direction of the fitting part. This is advantageous in particular for a concealed fitting.

In one embodiment of the invention can be provided that the guide has an undercut and the slider has a head portion with which it engages behind the guide in the region of the undercut. In particular, the guide may be T-shaped in cross-section. Because the slider with its head portion engages behind the guide in the region of the undercut, the slider is securely held on the guide. Forces generated by a wing acting on the slider can be absorbed without the slider becoming detached from the guide.

In one embodiment, the slider may be formed as Gleitniet. A Gleitniet consists of only one part and is therefore cheaper to manufacture and in the assembly as a two-piece glider. Although a two-piece slider (sliding element and Befestigungsniet) would have the advantage that the slider could lie flat against the guide and thereby lateral forces could initiate better in the leadership. The disadvantage lies in the fact that the two-piece glider is more expensive, since it consists of two parts and are mounted and joined in an additional operation got to. Furthermore, there is a risk that the sliding element breaks when the lateral forces are too great or the fastening rivet can be pulled out of the sliding element if the axial force is too great. The problem of the two-piece slider becomes greater the smaller the components (slider and fastener) become and the larger the forces that act.

When the guide sliding surface and the slider surface are matched, the slider must also be mounted in an appropriate position. Therefore, it is advantageous if the slide rivet has at its end to be fastened to the tab an alignment aid which is adapted to an alignment aid of the tab. Preferably, the slider has an alignment surface that cooperates with a corresponding surface or line of the tab. In particular, the contour of the slide rivet can be matched to the contour of a passage opening of the tab, so that the slider can be introduced into the tab only in the position predetermined by the contours. This can be avoided that wedges the slider in the guide and it comes to failure of the assembly.

In a preferred embodiment it can be provided that the slide rivet has an assembly aid, via which the slide rivet can be aligned in a riveting tool. The mounting aid is advantageously designed as a notch. About the notch, the slide rivet can be aligned in the riveting tool. This ensures that the Gleitniet sits properly in the rivet and the joining of the components is simplified.

A particularly good connection of the slider with the tab results when the slider is materially connected to the tab. This ensures a particularly good and secure mounting of the slider the tab secured. In this case, the slider can be expressed from the tab, pronounced or molded on it.

According to one embodiment, a second tab may be provided, which is pivotally connected to the first tab and the fitting part. Through the two tabs a scissor geometry can be realized, which allows exhibiting a wing.

Special. Benefits arise when a tab is thicker than the other. Thus, one of the tabs can be used to remove at least a portion, preferably the entire weight of a wing. The second tab may be made smaller in thickness if used exclusively or predominantly as a control tab. The fact that one tab is thinner than the other, the total height of folded tabs can be reduced, which is particularly advantageous for concealed fittings.

In one embodiment of the invention can be provided that the first tab has a Eckbandaufnahme, in particular a support pin has. This allows the weight of the wing to be transferred to the first tab. The first tab in turn rests on the second tab formed as a support tab and thus transfers the load to the support tab. The scissors geometry formed by the tabs is preferably chosen so that there is the greatest possible overlap of the control tab and the support tab. Thus, a resulting bending moment is kept low. This in turn spares the connection formed by the slider and the guide.

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

In a particularly preferred embodiment can be provided, the second tab is designed as a support tab and the fitting part as a base plate fastened to a frame, 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 pivotal connection of the fitting part and the second tab 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 fitting described above.

Further features and advantages of the invention will become apparent from the following description of embodiments of the invention, based on the Figures of the drawing, the invention essential details show, 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 the Figures 1 and 2 is designed as a corner bearing fitting 2 shown. This comprises a base part designed as a fitting part 5. A first tab 6 is pivotally connected to a second tab 7. The end 8 of the first tab 6 is displaceable along a guide 9 relative to the fitting part 5. The first tab 6 and the second tab 7 form a scissors geometry. In the exemplary embodiment, the scissors geometry is designed so that the wing is turned off as little as possible and still creates the largest possible clear width. With the fitting part 5 designed as a support tab second tab 7 is pivotally connected. When using the fitting 2 as Axerlager the pivotal connection of the fitting part 5 can be solved. To open the wing of this is just turned off so far from the frame, that there is no collision hiss the flashover and the frame.

The fitting 5 can be bolted to a frame. On the wing, a corner band 10 is provided, with which the wing is supported on the first tab 6.

A support pin 15 is from the first tab 6 from. On this support pin 15, the corner band sits 10. The support pin 15 forms a Eckbandaufnahme. The second tab 7 also has at its free end a bolt 16, which engages from below into the corner band 10. The weight of the wing is transmitted via the corner band 10 on the support pin 15. This then transmits the weight on the first tab 6. The first tab 6 rests on the second tab 7 and thus transmits the load on the second tab 7. The scissor geometry was chosen so that the greatest possible overlap of the first flap 6 and the second flap 7 is present with the wing open. Thus, a resulting bending moment is kept small. The second tab 7 must absorb a larger load than the first tab 6. Therefore, the second tab 7 is formed thicker than the first tab. 6

From the representation of FIG. 1 it can be seen that the guide 9 is executed bent. Through the ends of the guide 9, the movement of the first tab 6 is limited relative to the fitting part 5. The fitting part 5 and the second tab 7 together form a load-receiving device 20. For this purpose, the fitting 5 has a downwardly extending sleeve 21, in which a support pin 22 which is fixedly connected to one end of the second tab 7 protrudes. In this case, the second tab 7 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 to the occurring bending moment, which is introduced via the second tab 7 and the support pin 22. The sleeve 21 and the support pin 22 form a hinge. The forces occurring are transmitted to the fitting part 5 via the sleeve 21. This introduces the forces on the screw in the frame 1. Characterized in that the load-receiving device 20 projects downwards, in particular into the frame, the fitting 2 occupies only a small amount of space in the rebate air area.

By the sash weight, which acts on the first tab 6, the first tab 6 endeavors to tip over the second tab 7. Thus, there is a force on the first tab 6. This force endeavors to pull the slider 25 out of the guide 9. Due to the gravity of the wing, a force component in the horizontal direction is also exerted on the slider 25 via the first tab 6.

In the FIG. 1 It can be seen that the slider 25 at the end, with which it protrudes into the first tab, has an alignment aid 26 formed as an alignment surface. The breakthrough opening 27 of the first tab 6 also has an alignment aid. This means that the breakthrough opening 27 is not circular, but has a contour which is adapted to the slider 25, which is formed in the exemplary embodiment as Geleitniet. By this measure, on the one hand ensures that the slider 25 is properly inserted into the tab 6. In addition, thereby the rotationally fixed connection allows the slider 25 with the first tab 6.

In the FIG. 3 the slider 25 is shown. It can be seen that the slider 25 has a head portion 30 which is formed larger than the neck 31 of the slider 25. The head portion 30 has a substantially square basic shape. However, the Gleitstückflächen 32,33 rounded, and thus matched to the guide 9. Furthermore, the slider 25 has a trained as a notch mounting aid 34. At the end of the neck 31, the alignment aid 26 can be seen.

In the FIG. 4 is a plan view from below of the slider 27 is shown. In particular, the alignment aid 26 becomes clear again here.

The sectional view of FIG. 5 according to the line IV - IV of FIG. 4 it can be seen that the slider 25 is constructed stepwise. The step shape 37 corresponds to an inner contour of the guide. 9

In the FIGS. 6 to 9 the fitting 2 is shown with different opening positions. The FIG. 6 shows the position of the fitting 2 with the wing closed. In this position, the slider 25 is almost in an end position in the guide 9. The arrows 40,41 point to points of contact of Gleitstückflächen 32,33 with the Führungsgleitflächen 42, 43. Der FIG. 6 it can also be seen that the guide 9 has an undercut 44, which is engaged behind by the head portion 30 of the slider 25. This ensures that the first tab 6 does not lift off the fitting part 5.

In the FIG. 7 a first opening position of the wing is shown. This means that the second tab 7 is folded away from the fitting part 5. During this small opening movement is a shutdown of the wing. This means that the slider 25 first passes into a right end position of the guide 9. The arrows 40, 41 point again to points of contact of the surfaces 32, 33 with the surfaces 42, 43. It can be seen that now there are other points of contact than in the FIG. 6 , This means that the sliding surfaces 32, 33 of the slider 25 are adapted to the guide sliding surfaces 42, 43 such that the points of contact between the surfaces 32, 33, 42, 43 constantly change as the slider 25 moves in the guide 9.

In another opening movement, in the FIG. 8 is shown, the slider 25 moves in the figure to the left along the guide 9. Again, other points of contact are present, as shown by the arrows 40,41.

In a full open position, which in the FIG. 9 is shown, the slider 25 is moved to a second end position in the guide 9. Again, other touch points or lines of contact result, as indicated by arrows 40,41.
