Description

fitting part with halves that can be mounted one after the other

Background of the invention

The invention relates to a fitting part for fastening to a profile groove of a window or a door, wherein the profile groove extends in its longitudinal axis and has a first web which extends radially inwards and, opposite the first web, has a second web which extends radially inwards, wherein the fitting part has a first body with a first foot section for engaging behind the first web and the fitting part has a second body with a second foot section for engaging behind the second web.

It is known that fittings with opposite foot sections can be inserted into profile rails with almost no play, so that the foot sections engage behind opposite webs of the profile rail. However, if the profile rails are closed at both ends when installed, the fittings cannot can no longer be dismantled from the profile rail and no fittings of this type can be added subsequently.

There are therefore considerations to design a fitting part in such a way that, on the one hand, it is firmly mounted on a profile rail, but on the other hand is easy to assemble and disassemble.

EP 1 493 889 A1 discloses a locking plate which has two opposing foot sections in order to engage behind webs of a profile rail. The locking plate is pivoted with a first foot section under a first web of the profile rail and then pivoted with the opposite foot section under the opposite web. A disadvantage of the known locking plate, however, is that the locking plate has a large amount of play in the profile rail in order to enable the locking plate to pivot into the profile rail.

The generic EP 1 619 334 A2 discloses a door hinge with a first part that has a first foot section for insertion under a first web of a profile rail. The door hinge has a second part with a second foot section that can engage behind a second web of the profile rail. The two parts can be mounted on top of each other. However, the arrangement of the two parts on top of each other leads to a relatively large construction height of the door hinge.

A similar functional principle is known from EP 1 972 743 A1. The locking part shown in EP 1 972 743 A1 has two parts that can be mounted on top of one another, each of which has a foot section, wherein the foot sections extend in opposite directions in the assembled state of the locking part in order to engage behind a web of a profile rail.

EP 2 514 892 A1 discloses a system for fastening a fitting part with a joint. The joint connects two parts of the system, each of which has a foot section for engaging behind opposite webs of a profile rail.

EP 3 091 157 A1 discloses a locking part with a base block and a clamping piece. The base block has a first foot section and the clamping piece has a second foot section extending in the opposite direction. The clamping piece can be moved relative to the base block by means of a spindle screw. This allows the locking part to be partially inserted into a profile rail and the spindle screw can then be operated in order to further distance the two foot sections from each other and to engage behind webs of the profile rail.

However, the two aforementioned embodiments are relatively complex in terms of construction.

EP 3 396 084 A1 discloses a fitting part that can be pivoted about a rotation axis in the groove of a profile rail. The fitting part is designed asymmetrically to its rotation axis so that it can be clamped in the groove by pivoting about its rotation axis.

The fittings known from the state of the art are therefore either structurally complex or their connection has only a low strength when assembled or they cannot be subsequently mounted or dismantled on profile rails that are closed at both ends.

task of the invention

It is therefore the object of the invention to provide a fitting part that is easy to install, has a simple construction and whose connection has a high level of strength. It is also the object of the invention to provide a fitting part arrangement with such a fitting part and a window or a door with such a fitting part arrangement. Finally, it is the object of the invention to provide a method for installing such a fitting part. Description of the Invention

This object is achieved according to the invention by a fitting part according to claim 1, a fitting part arrangement according to claim 11, a window or a door according to claim 13 and a method according to claim 14. The dependent claims give preferred embodiments.

The object according to the invention is thus achieved by a fitting part as described at the outset, in which the first body and the second body can be pivoted independently of one another into the profile groove about their respective longitudinal axes, can be moved towards one another in the direction of their respective longitudinal axes and can be fixed to one another with aligned longitudinal axes, so that the bodies, viewed in the direction of the longitudinal axis of the profile groove, are at least partially arranged one behind the other.

On the one hand, the fitting part is easy to assemble due to the division of the foot sections into the two bodies, but can still form a firm connection with the profile groove when assembled.

When the fitting is assembled, the two foot sections protrude in opposite directions. When the fitting is not assembled, one body can be swiveled into the profile groove clockwise - viewed in the direction of the longitudinal axis of the profile groove - and the other - viewed in the same direction - can be swiveled into the profile groove anti-clockwise.

When the fitting is assembled, the bodies can overlap when viewed in the direction of the longitudinal axis of the profile groove, so that the longitudinal axes of the bodies are not only aligned but also overlap.

The fitting part has at least two bodies, in particular exactly two bodies. The bodies can be formed in one piece (single part). The fitting part can be anvil-shaped. In the assembled state, the fitting part is preferably designed symmetrically to a central plane extending perpendicular to the longitudinal axes of the base bodies, except for the foot sections.

The fitting part can have a first threaded pin with a first external thread which engages in a first internal thread of the first body, so that the first threaded pin can be screwed in and out transversely to the longitudinal axes of the bodies in order to be able to clamp the fitting part in the profile groove.

The first threaded pin can be designed in the form of a screw. The first threaded pin is preferably designed in the form of a grub screw in order to be able to fix the fitting part flexibly in profile grooves of different depths.

The first threaded pin can also fasten the first body to the second body. The first threaded pin can therefore fulfil a dual function and both fix the fitting part in the profile groove and fix the first body to the second body.

The fitting part can further comprise a second threaded pin with a second external thread which engages in a second internal thread of the second body, so that the second threaded pin can be screwed in and out transversely to the longitudinal axes of the bodies in order to be able to clamp the fitting part in the profile groove.

The second threaded pin can be designed in the form of a screw. The second threaded pin is preferably designed in the form of a grub screw in order to be able to fix the fitting part flexibly in profile grooves of different depths.

To facilitate the assembly of the fitting, the first threaded pin and the second threaded pin can be of the same design. The fitting part can also have a third threaded pin to fasten the first body to the second body. The third threaded pin is preferably designed in the form of a screw, in particular with a screw head, so that it can be easily operated by a user. This makes it easier to handle the fitting part as long as the two bodies are not yet fixed in the profile groove and holding the movable individual parts of the fitting is laborious.

The fitting part can have a cover plate section that can be placed on webs of the profile groove and that extends over the first body and the second body. The cover plate section prevents the fitting part from being immersed too deeply in the profile groove. The cover plate section can be formed partly on the first body and partly on the second body. The fitting part can have a T-shaped cross-section along the longitudinal axes of the base bodies, from which the foot sections protrude, with the cover plate section forming the top of the T-shape.

To support the cover plate section, the profile groove can have a third web projecting radially inwards and extending parallel to the longitudinal axis of the profile groove and a fourth web projecting inwards and extending parallel to the longitudinal axis of the profile groove, opposite the third web.

In a particularly preferred embodiment of the invention, the bodies are connected in a form-fitting manner at least in sections when the fitting part is in the assembled state. This allows both the strength of the connection between the bodies and the strength of the connection of the fitting part to the profile groove to be significantly increased.

The first body and the second body can be identical and/or mirror-symmetrical to each other. The identical or mirror-symmetrical design of the bodies facilitates the manufacture and assembly of the fitting part. The first body and/or the second body can be designed in the form of a metal casting. This allows the bodies to be manufactured cost-effectively despite the protruding foot sections. The bodies are particularly preferably designed in the form of zinc die-cast parts or steel die-cast parts.

The first threaded pin can connect the first body directly to the second body. In particular, the first threaded pin can be inserted into a recess in the first body as well as into a recess in the second body.

The first body can be held directly in a rotationally fixed manner, in particular with respect to the longitudinal axis of the fitting part, on the second body by means of a positive connection. In particular, a projection of the first body extending in the direction of the longitudinal axis can be accommodated in a recess of the second body extending in the direction of the longitudinal axis.

The fitting part can be designed, for example, in the form of a window or door hinge. The fitting part is preferably designed in the form of a locking piece for hooking onto a locking pin and/or a locking hook. For this purpose, the first body and/or the second body can have a projection that can be gripped behind by the locking pin or locking hook.

The object according to the invention is further achieved by a fitting part arrangement with a profile rail which has a profile groove, and a fitting part as described here which is fastened to the profile groove, wherein the profile groove has a first web which extends parallel to the longitudinal axis of the profile groove and projects radially inwards, and a second web which extends parallel to the longitudinal axis of the profile groove and projects radially inwards, wherein the first foot section surrounds the first web and the second foot section surrounds the second web. The profile groove preferably has a constant cross-section along its longitudinal axis. The profile rail is preferably designed in the form of an extruded profile, in particular made of aluminum.

The profile groove can be designed to be mirror-symmetrical to a center plane that intersects the longitudinal axis of the profile groove. In a particularly preferred embodiment of the fitting part arrangement, the longitudinal axis of the first threaded pin extends parallel to or in the center plane and perpendicular to the longitudinal axis of the profile groove.

The object according to the invention is further achieved by a window or a door with a fixed frame, a sash and a fitting arrangement described here.

Preferably, the fixed frame has the profile rail.

The fixed frame is also preferably made of aluminum. The arrangement according to the invention is particularly effective for windows or doors with fixed aluminum frames because drilling should be avoided when attaching fittings to aluminum windows or doors.

The object according to the invention is finally achieved by a method for assembling a fitting part arrangement described here with the method steps:

A) pivoting the first body about its longitudinal axis into the profile groove so that the first foot section engages behind the first web;

B) pivoting the second body about its longitudinal axis into the profile groove so that the second foot section engages behind the second web; wherein the process steps A) and B) are carried out in any order or simultaneously, and wherein the bodies are pivoted in particular in opposite directions;

C) Bringing the bodies together in the direction of their longitudinal axes until the bodies touch each other, whereby the longitudinal axes of the bodies coincide with the longitudinal axis of the profile groove or run parallel to the longitudinal axis of the profile groove.

In addition, the method may comprise the following step:

D) Screw in the first threaded pin until the fitting is clamped in the profile groove.

Preferably, the method also comprises screwing in the second threaded pin. Alternatively or additionally, the method may comprise connecting the bodies with the third threaded pin.

Further advantages of the invention emerge from the description and the drawing. Likewise, the features mentioned above and those described below can be used individually or in combination in any desired way. The embodiments shown and described are not to be understood as an exhaustive list, but rather are exemplary in nature for describing the invention.

Finally, Fig. 1e shows the window 10 with the fitting part 20 completely assembled, with the first threaded pin 24a screwed in to connect the two bodies 22a, b and to clamp the fitting part 20 in the profile groove 16.

Fig. If shows a part of a fitting part arrangement 28, consisting of the profile rail 14 with the profile groove 16 and the fitting part 20. From Fig. 1f it can be seen that the first body 22a has a first foot section 30a for engaging behind a first web 32a of the profile rail 14 and the second body 22b has a second foot section 30b for engaging behind a second web 32b of the profile rail 14.

A cover plate section 34 with a first head section 36a and a second head section 36b rests on a third web 32c and a fourth web 32d of the profile rail 14.

The first threaded pin 24a presses, in particular vertically, onto the groove base 38 of the profile groove 16.

The first web 32a and the second web 32b, and preferably also the webs 32c, d, can be designed symmetrically to a center plane 40 intersecting the longitudinal axis 18 (see Fig. 1a) of the profile groove 16. Particularly preferably, the first web 32a and the third web 32c are C-shaped and the second web 32b and the fourth web 32d are mirrored about the center plane 40.

In a particularly preferred embodiment of the fitting part arrangement 28, the longitudinal axis 41 of the first threaded pin 24a extends parallel to or in the center plane 40 and perpendicular to the longitudinal axis 18 (see Fig. 1a) of the profile groove 16. In order to enable the first foot section 30a to grip onto the first web 32a, the first foot section 30a can have at least one first tooth 42a. In order to enable the second foot section 30b to grip onto the second web 32b, the second foot section 30b can have at least one second tooth 42b (see also Fig. 1g).

Fig. 1g shows the fitting part 20. From Fig. 1g it can be seen that the two bodies 22a, b form a positive connection 44 in the assembled state.

Fig. 1h shows the fitting part 20 in a side view. The first threaded pin 24a has a first external thread 46a, which engages in a matching first internal thread 48a of the first body 22a.

Fig. li shows a top view of the fitting part 20, from which it can be seen that the first threaded pin 24a is designed in the form of a grub screw. The first threaded pin 24a preferably has a polygon socket 50 at one end, here in the form of a hexagon socket.

A first threaded pin 24a is guided in the first body 22a and a second threaded pin 24b in the second body. The two bodies 22a, b can be connected via a positive connection 44 and a third threaded pin 24c.

Figs. 2b, c show the fitting part 20 in the assembled state on its own. From a view of Figs. 2b, c together, it is clear that the fitting part 20, except for the formation of the positive connection 44, can be formed symmetrically to the longitudinal axis 52 of the third threaded pin 24c.

Fig. 3a shows a further example of a fitting part arrangement 28 with a profile groove 16 and a fitting part 20 which can be fastened to or in the profile groove 16. The fitting part 20 has a first body 22a in which a first thread destift 24a is guided, and a second body 22b, in which a second threaded pin 24b is guided. The first body 22a is designed identically to the second body 22b. This can significantly simplify the manufacture and assembly of the fitting part 20. The first threaded pin 24a has a first external thread 46a, the second threaded pin 24b has a second external thread 46b. The first threaded pin 24a can be designed identically to the second threaded pin 24b.

Figs. 3b-e show the fitting part 20 in the assembled state on its own. The anvil-shaped design of the fitting part 20 is particularly evident in Fig. 3d. Furthermore, Fig. 3d indicates that a first internal thread 48a matching the first external thread 46a (see Fig. 3a) and a second internal thread 48b matching the second external thread 46b (see Fig. 3a) are formed in a cover plate section 34.

Taking a look at all the figures in the drawing, the invention relates in summary to a fitting part arrangement 28 with a profile rail 14 having a profile groove 16 and a fitting part 20 that can be mounted on the profile rail 14. The fitting part 20 has a first body 22a with a first projecting foot section 30a and a second body 22b with a second projecting foot section 30b.
