Description

description

The invention relates to a system with a hardware element and a profile, and the system has at least two clamping elements for fixing the hardware element on the profile.

A similar system is already known, for example, from EP 2347073 B1. The disadvantage of known systems is that they do not under any circumstances, for example, with profiles with the widest groove, provide the desired combination of a high maximum permissible load, adaptability to simple installation and cost-effective manufacturability.

The invention set itself the task of creating a system that is improved with respect to at least one of the indicated shortcomings.

This task is solved with the help of the system specified in Clause 1 of the claim.

The system according to the invention includes a hardware element and a profile. Speaking about the hardware element, we can be talking about the hinge element for the rotary connection of the sash with the frame. Speaking of a hardware element, we can be talking about a hinge element for doors, windows, and the like.

The profile has a longitudinal direction and includes a longitudinal groove with an opening of the groove that defines the plane. The groove has two opposite undercuts. To fix the hardware element on the profile, the system has at least two clamping elements that can be rotated between the mounting position and the fastening position. Clamping elements interact in the fastening position, respectively, with only one undercut. Predominantly, the clamping elements in their fastening position enter the protrusion into the undercut engagement, preferably, respectively, with only one undercut of the groove.

Clamping elements in the installation position mostly do not interact with the profile. Due to the undercuts, the groove can preferably also be referred to as an undercut groove or an undercut longitudinal groove. Due to the fact that each clamping element interacts with only one undercut, conditions are created for the fastening to withstand a special load, even with the widest grooves, that is, undercuts located the most widely apart from each other.

The fastening position of the clamping elements differs from the mounting position mainly by turning the 902 clamping elements. Clamping tools can within this framework

From the patent application, it is also indicated mainly as fastening screws. Clamping elements may also be referred to preferably as clamping crackers within the scope of this patent application.

Preferably, if viewed in the longitudinal direction of the profile, two clamping elements are provided in height. As a result, an even effort can be applied to the profile through both sides.

The axis around which the clamping elements can rotate is preferably perpendicular to the opening plane of the groove.

Clamping elements mainly have a main body, which is most preferably axisymmetric.

Clamping elements preferably have a protrusion, which is further preferably made protruding in the radial direction.

Preferably, each clamping element has two protrusions projecting in the radial direction.

Both performances are mostly opposite to each other. Clamping elements can respectively have only one projection. A protrusion can extend to an angle greater than 18092.

Preferably, the clamping elements are fixed with a clamping screw on the hardware element.

Predominantly, the clamping elements have a threaded hole with which the clamping screw engages. The clamping screw passes preferably through the hole in the fitting element.

This hole is mainly made in the form of a stepped hole.

The diameters of the main bodies and/or the length of the protrusions and/or the location of the holes in the fitting element are preferably selected in such a way that the assembly, which consists of the clamping element, the clamping screw and the fitting element, can thus be displaced perpendicular to the opening plane of the groove, that the clamping elements can be introduced by their protrusions into the groove - preferably if the protrusions of the clamping elements are not directed outwards - and holding forces can be transmitted through the clamping elements - preferably if the protrusions are directed outwards. The protrusions are preferably located on the side of the clamping elements remote from the hardware element.

Preferably, the fitting element can be brought to the mounting position on the profile using a purely translational mounting movement. This has the advantage that, unlike, for example, a rotary assembly movement, further fastening means can be provided in the simplest way, which increase the maximum allowable load of fastening the fitting element to the profile. The mounting position of the clamping elements, in particular in the variant of implementation 60 in which the fitting element can be brought to the mounting position by means of a purely translational mounting movement on the profile, can preferably also be referred to as the insertion position.

Further fastening means preferably include at least one protrusion on the profile and at least one groove on the fitting element, and the protrusion is included in the mounting position of the fitting element in engagement with the groove of the fitting element.

Preferably, there are two protrusions opposite to opening the groove and two grooves of the hardware element interacting with these protrusions. Thus, the most stable connection of the hardware element on the profile can be achieved, in particular against the overturning of the hardware element.

The protrusion on the profile can have a locking recess. In the groove of the hardware element, a locking nose can be provided, which engages with the locking recess.

Thus, it may already be possible to position the fitting element before the protrusions of the clamping elements enter the undercut engagement with undercuts of the groove.

In principle, it is possible that the protrusion or protrusions are located not on the profile, but on the fitting element, and the groove or grooves are located not on the fitting element, but on the profile.

Preferably, by driving the corresponding clamping screw in a rotary motion, the corresponding clamping element can, preferably due to the frictional locking of the thread of the clamping screw with the threaded hole, return from the mounting position to the fastening position.

Preferably means are provided to increase the friction of the cuts, preferably between the clamping screw and the clamping element. These means may include the fact that the threads of the clamping screw and the clamping element are not made, as in the case of a conventional threaded connection, completely corresponding to each other, and, for example, either the thread of the clamping screw or the thread of the clamping element have an error of the cutting pitch. As a result, it is preferably ensured that by turning the corresponding clamping screw, the corresponding clamping element is returned from the mounting position to the fastening position. Due to the increase in the tightening torque associated with the increased friction of the cutting, the fitter thus mainly receives feedback about the position of the corresponding clamping element. Mainly due to the increased friction of the thread, an increase in the tightening moment is achieved as soon as it is clamped

The element is in the fastening position. This increase in tightening torque signals the fitter primarily that the rotation of the clamping element is complete in the fastening position.

In principle, it is possible that the clamping elements are not fixed with a clamping screw on the hardware element, but with a clamping nut, and that the clamping elements do not have a threaded hole, but an external thread. The above-described means for increasing the friction of the cuttings can be provided in this case between the clamping element and the clamping nut.

Preferably, a friction lock is made between the clamping screw and the hardware element, preferably in such a way that, for example, during transportation or storage of the unit consisting of the clamping element, the clamping screw and the hardware element, spontaneous torsion between the clamping screw and the hardware element does not occur. Thus, each clamping element can be brought into the installation position, preferably in factory conditions, and it can be ensured that the clamping elements still occupy this position also during installation. Since the unwanted twisting of the clamping elements relative to the corresponding clamping screw can be avoided by the already mentioned, preferably provided means for increasing the friction of the threads between the clamping screw and the clamping element. Undesired rotation of the clamping screw together with the corresponding clamping element can be avoided by the preferential frictional locking between the clamping screw and the fitting element.

Means for increasing the friction of cuts can therefore have a dual function. On the one hand, they can ensure that by turning the corresponding clamping screw, the corresponding clamping element is returned from the mounting position to the fastening position. On the other hand, they can prevent unwanted rotation of the clamping element.

Friction locking can be accomplished by providing a tension fit between the clamping screw and the hardware. The threaded screw can for this purpose have a screw body or an external thread, the outer diameter of which, according to the distribution of tolerances between the clamping screw and the hardware element, is slightly larger than the internal diameter of the corresponding hole in the hardware element, through which the clamping screw preferably passes accordingly.

Undercuts preferably have in each case at least one, preferably two boundary surfaces, namely preferably a support surface and then preferably a support surface.

The clamping elements adjoin in their fastening position mainly to the boundary surface, preferably to the support surface, and abut further, mainly in this position, to the support surface. Mainly clamping forces are introduced through the support surface, which hold the fitting element on the profile. The contact surfaces mainly prevent excessive rotation of the clamping elements. Instead of or in addition to the abutment surfaces on the profile, the abutment surfaces can be provided on the fitting element with the same purpose.

Preferably, the clamping elements have edge sections which, during the assembly movement, are turned to the opening plane of the groove and then preferably directed outwards, and these edge sections are further provided with a mostly beveled surface, in order to facilitate the introduction of the clamping elements into the groove during the assembly movement. In these marginal areas, the protrusion mostly does not spread.

Preferably, the clamping forces between the profile and the clamping elements act on the clamping element only on one side of its axis of rotation. In order to deflect or reduce the bending load of the clamping screw, the clamping elements preferably have two opposing protrusions or one protrusion extending more than 1802, and the hardware element preferably has a counter-port with which one of the two protrusions or a portion of the protrusion interacts in the clamping position elements. Preferably, a projection that does not interact with the profile, or a section of the projection interacts with the counterpoise. As a result, the bending load or overturning of the clamping screw is avoided. It has been found that, despite the fact that, as a result, part of the screw force is not available for clamping, but acts inside the fitting, sufficient clamping force can be applied.

The protrusions of the clamping elements can have a toothed crown, which in the fastening position of the clamping elements cuts into the profile and/or into the hardware element.

To deflect the one-sided load of the clamping element and the consequent overturning of the clamping element or the clamping screw, the counter-prop serves as a support for the clamping element mainly in the direction of its axis of rotation.

To prevent overturning of the clamping element or clamping screw, means are preferably provided that cause resistance of the clamping element, which acts in the radial direction, that is, perpendicular to its axis of rotation. These means include a predominantly axisymmetric main body of the clamping element, which then preferably interacts with the corresponding opening of the hardware element. This hole extends preferably only on one side of the respective clamping element, namely on the side facing away from the nearest undercut of the profile, so that the overturning of the clamping element on this side is preferably averted. Therefore, this hole is mostly not cylindrical, but only partially cylindrical. This opening is preferably located in the protrusion of the hardware element, which extends further mainly only on one side of the corresponding clamping element, namely preferably on the side facing away from the nearest undercut of the profile. In the unloaded state, the main body is located mainly with a slight gap in the corresponding opening of the fitting element. A significant overturning of the clamping element is mostly avoided due to the fact that already at the very minimum overturning that begins, this gap is reduced to zero, and the main body abuts the opening.

Preferably, the protrusion of the hardware element, in which the hole for radial resistance of the clamping elements is located, simultaneously provides a counter-support for the resistance of the clamping element in the direction of its axis of rotation. This protrusion is located mostly not perpendicular to the opening plane of the groove, but passes at an angle to it. Preferably, the fitting element has two similar protrusions, which are then preferably opposite to each other. The protrusions are located preferably in such a way that they converge with each other at an angle to the opening plane of the groove.

As approximately shows Fig. 1, indicated in general by the reference item 100, the system of the shown example of implementation includes a hardware element 1 and a profile 2, which has a longitudinal direction H. In Fig. 1, its longitudinal direction is perpendicular to the plane of the drawing, which is symbolically shown by a circle with a cross. The profile 2 has a longitudinal groove C with an opening 4 of the groove defining the plane E, and two opposite undercuts 5, 5. To fix the hardware element 1 on the profile 2, at least two clamping elements 8 are provided (in the example shown, exactly four, see Fig. 2), which can be rotated between the mounting position M and the mounting position H. In its mounting position H, each clamping element 8 interacts with only one undercut 5, 5, see, for example, Fig. 11. As can be seen, for example, from Fig. 4 and 12, if viewed in the longitudinal direction of the GI. profile 2,

Two clamping elements 8 are provided at the height of Z. The clamping elements can be rotated around the axis A, which runs perpendicular to the plane E of opening 4 grooves. As approximately shows Fig. 17, each clamping element 8 has an axisymmetric main body 8a, from which, on the side facing away from the hardware element 1, only one projection 9 protrudes in the radial direction, extending to an angle a greater than 1802. Only on one side 17 does the clamping element not have a projection from the main body and protrusion 9.

The diameters of the main bodies and the length of the protrusions 9, 9 are selected in such a way that the assembly 15, consisting of the clamping element 8, the clamping screw 10, and the hardware element 1, can thus move perpendicularly to the plane E of the opening 4 of the groove, that the clamping elements 8 can be inserted with their protrusions 9 in the groove 3, if the protrusions 9 of the two clamping elements are not directed outwards, and accordingly if the side 17, on which the clamping element 8 does not have a protrusion from the main body and the protrusion 9, is directed outwards (see, for example, Fig. 1). Fig. 1 also shows that the fitting element 1 can be brought into the mounting position on the profile 2 by means of a purely translational assembly movement B. For example, Fig. 5 and 17 show that the clamping elements 8 have a threaded hole 18 and interact with the clamping screw 10, which passes through the hole of the hardware element 1.

Fig. 17 also shows that both protrusions 9 are combined into one protrusion that extends to an angle α greater than 1802.

For example, looking at Fig. 5 and 10, as well as 12, it can be seen that by driving the corresponding clamping screw 10 into a rotary movement, the corresponding clamping element 8 can, thanks to the frictional closing of the thread of the clamping screw 10 with the threaded hole 18, turn from the position M of the insert to the fastening position H. For example, with fig. 10 and 12 it follows that the undercuts 5, 5, respectively, have two boundary surfaces 6, 7, namely the bearing surface ba and the bearing surface 7a, and the clamping elements 8 fit in the fastening position H to the bearing surface ba and abut against the bearing surface 7a. Further support surfaces 20 are provided on the hardware element 1, against which the clamping elements 8 also abut in the fastening position H.

As can be seen, for example, from an overview of Fig. 1 and 5, the clamping elements 8 have edge sections which, during the installation movement B, are turned to the plane E of opening the groove and are directed outward, and these edge sections are provided with a beveled surface 12, in order to facilitate the introduction of the clamping elements 8 into the groove 3.

For example, from Fig. 14 to 16, it follows that the clamping elements 8 have a protrusion 9 extending to an angle of more than 1802, and the hardware element 1 has a counterporous 11 with which the section of the protrusion 9 interacts in the fastening position H of the clamping elements 8.

Fig. 1 also shows that the profile has two protrusions 13, 137, and the hardware element 1 has two grooves 14, 14, and both protrusions 13, 13 are included in the mounting position OO of the hardware element 1 in the engagement, respectively, with the groove 14, 14" of the hardware element 1 .

From Fig. 5 it follows that the protrusions 9 of the clamping elements 8 have a toothed crown 16, which in the fastening position cuts into the profile 2 (see Fig. 10). Also, the hole 19 of the fitting element 1 can be seen in this figure, and it is shown that it is made in the form of a stepped hole.

The hardware element 1 has two opposite protrusions M, which are not located perpendicular to the plane E of opening the groove, but converge at an angle to it (see, for example, Fig. 1). As an alternative to that shown in the figures, each protrusion may not only have one slope to the plane E of opening the groove side, but both sides of the protrusion may run at least substantially parallel to each other and inclined to this plane E. These protrusions M provide, respectively, a counter-support 11, which serves a support for the clamping element in the direction of its axis A of rotation. The partially cylindrical section of the stepped opening 19 in the protrusion M interacts with the main body and in addition to prevent the clamping element 8 or the clamping screw from tipping over in the sense of the radial resistance of the clamping element 8 (Fig. 5).

Fig. 5 also shows that in the area of the stepped hole 19 in the fitting element 1, which is directly penetrated by the clamping screw 10, there is a fit P with tension between this clamping screw 10 and the stepped opening 19, while in the area of the stepped opening 19, in which the the main body va of the clamping element 8, there is a landing 5 with a gap between the main body va and the stepped hole 19.

Fig. b to 9 clearly show the return of the clamping elements 8 from the position M of the insert (shown in Fig. 6) to the fastening position H (shown in Fig. 9). In Fig. 7 clamping elements are rotated relative to the position M of the insert by 22.57, in Fig. 8 by 66 g, and shown in Fig. 9, the fastening position H differs from the position M of the insert by turning the clamping elements 8 by 902. The clamping elements are turned by turning the ones shown, for example, in Fig. 13 fastening screws 10.

The surfaces on the hardware element 1 and the profile 2, in other words the abutment surface 7a on the profile 2 and the further abutment surfaces 20 on the hardware element 1, prevent that the clamping elements can be turned further than 902.

Fig. 14 shows a situation in which the clamping elements are returned by turning the clamping screws 10 to the fixing position H, but the clamping screws 10 are not yet tightened further. Due to the further rotation of the fastening screws 10, the clamping element moves in the direction of the axis A of the screws, as a result of which the toothed crown 16 of the clamping elements 8 comes into contact with the profile 2 for the first time (this is shown in Fig. 15). Due to the further rotation of the clamping screws 10, the clamping elements 8 are moved even further in the direction of the axis A of the screws. The clamping elements 8 then come into contact with the hardware element 1 for the first time. As a result, the overturning of the clamping elements 8 is prevented. The toothed crown 16 cuts into the profile 2.

For example, Fig. C shows that the node 15 can be freely inserted by the clamping elements 8, which are in the position M of the insert, into the groove 3.

Undercuts 5, 5 of profile 2 can be made in different ways. Fig. 18 and 19 schematically show further examples.
