Description

[0001] The present connection relates to a T-connection for a facade or a window, with a first profile which rests on a second profile at one end face and at least one connecting element is arranged in a receptacle of the first profile and passes through a wall of the second profile and is fixed to the second profile via a fastening means, as well as a method for assembling a T-connection.

[0002] DE 20 011 197 U1 discloses a T-connection between a mullion profile and a transom profile of a facade, in which a fastener is fixed in a transom via a screw. To secure the transom, a connecting pin is provided, which is inserted into a screw channel of the transom. The transoms have a notch and cover a receptacle on the mullion with a protruding section. The production of such a T-connection is comparatively complex and involves numerous assembly steps.

[0003] EP 1 681 398 B1 discloses a T-connection in which T-connectors are fixed to the transom profiles. These T-connectors have a locking bar on a locking section that is preloaded into the locking position by a spring. This allows the locking sections to be inserted into an opening in the post. This simplifies assembly on site, but the fixation of the T-connectors and their manufacture with the locking bars remains complex.

[0004] It is therefore an object of the present invention to provide a T-connection for a facade or a window and a method for assembling a T-connection, which enable two profiles of a T-connection to be fixed using simple means.

[0005] This object is achieved with a T-connection having the features of claim 1 and a method for assembling a T-connection having the features of claim 10.

[0006] The T-connection according to the invention comprises a first profile which rests on a second profile at one end face and has at least one

[0007] Connecting element is arranged in a receptacle of the first profile and passes through a wall of the second profile and is fixed to the second profile via a fastening means. Before being fastened to the second profile, the at least one connecting element is guided displaceably on the receptacle on the first profile and is prestressed by a spring element, in particular prestressed in a direction towards the second profile. As a result, the at least one connecting element can be pre-assembled in the receptacle of the first profile and can then be moved along the receptacle from the assembly position into a protruding fastening position for fastening to the second profile via the spring element in order to be fixed to the second profile via the fastening means. This simplifies assembly since the first profile can be securely fixed to the second profile using only a few components.

[0008] Preferably, the at least one connecting element is fixed to the first profile via a further fastening means. The fastening means can each be designed as a screw. The first profile or the second profile can be clamped to the connecting element via the screw. A head of the screw can be received in a groove in the first profile or the second profile, so that the fastening means are not or barely visible from the outside. The groove can be used to insert sealing profiles, so that the head of the screw is also covered by them.

[0009] The receptacle for guiding the at least one connecting element can be designed as a groove or channel which extends in the longitudinal direction of the first profile. The connecting element can optionally be displaced in the longitudinal direction, but not rotated, for example if the connecting element and the receptacle have a cross-section which deviates from a circular shape. The connecting element can for example be designed as an elongated pin, in particular made of metal. One or more openings for the introduction of fastening means can be formed in the pin. Preferably, at least two spaced-apart openings are provided in the connecting element for inserting one of the fastening means, so that these can be introduced at predetermined positions and the first profile and the second profile can be provided with openings at these positions.When inserting the fasteners, the connecting element can optionally be expanded to clamp it into the receptacle. For this purpose, the fastener can be designed, for example, as a bolt with a slot that allows for such expansion.

[0010] For a stable fixation of the first profile and the second profile, two spaced-apart connecting elements can be arranged between the first profile and the second profile. Each connecting element can be provided in a receptacle, for example in a channel adjacent to a groove. The first profile can be designed symmetrically to a central plane parallel to the longitudinal direction, so that a connecting element for fixing the first profile to the second profile is provided on both sides of such a central plane. Alternatively, only a single connecting element can be provided, which is slidably guided in a corresponding groove or receptacle.

[0011] In a preferred embodiment, the first profile and the second profile have the same cross-section, so that the T-connection can be produced with few components.

[0012] The T-connector can be used in a facade, for example, in a mullion-and-transom construction with butt-cut transom profiles mounted on a mullion. Alternatively, a notch or recess can be provided on the transom into which a section of the mullion is inserted. The T-connector can also be used in unitized facades, windows, or doors. Furthermore, the T-connector can also be used for furniture or structural elements.

[0013] The first profile and the second profile are preferably extruded profiles, for example, made of metal and / or plastic. The profiles can have different visible widths.

[0014] In a method according to the invention for assembling a T-connection, a connecting element is pushed into a receptacle of a first profile against the force of a spring element arranged in the receptacle and then fixed in the pushed-in position by a fastening means. Optionally, several connecting elements can each be pushed into different receptacles on the first post and fixed in place. In this pre-assembled position, the first profile can be brought to the construction site. The connecting element can be arranged essentially flush with the front side of the first profile and does not protrude. In a next step, the fastening means can be released in order to slide the connecting element along the receptacle using the force of the spring element, wherein the connecting element is inserted through an opening in a wall of a second profile.The connecting element is then fixed to the second profile using a fastener. This allows a quick connection between the first profile and the second profile to be achieved on site by loosening the fastener on the first profile and fixing the connecting element to the second profile using a fastener. Optionally, two connecting elements are provided on the first profile, each of which is fixed to the second profile using a fastener in the fastening position.

[0015] The connecting element can be fixed to the first profile using additional fastening means. For example, the fastening means that was used to release the connecting element from the mounting position can be reinserted after the connecting element has been moved in the longitudinal direction of the first profile in order to fix the connecting element in a fastening position on the first profile. For this purpose, a plurality of spaced-apart openings or internal threads can be provided on the connecting element, by means of which the connecting element can be fixed to the first profile in different positions. The fastening means are preferably introduced perpendicular to the sliding direction of the connecting element, in particular also perpendicular to the longitudinal direction of the first and second profiles.

[0016] A stop is preferably arranged in the receptacle on the first profile, against which the spring element is supported. This stop can optionally be formed by a screw or other fastening means. This stop limits the insertion depth of the spring element, which is compressed when the connecting element is inserted.

[0017] The invention will be explained in more detail below using an exemplary embodiment with reference to the accompanying drawings. Fig. 1 is a perspective view of a T-connection according to the invention; Fig. 2 is a perspective view during assembly of two connecting elements on a first profile; Fig. 3 is a view during fixing of the connecting element to the first profile for a transport position; Fig. 4 is a perspective view of the first profile after releasing the two connecting elements; Fig. 5 is an exploded view of the T-connection of the Figure 1during assembly; Fig. 6 a detailed view of the fastening means on the first profile, and Fig. 7 a view of the T-connection in the fastening position.

[0018] A T-connection 1 for a facade or a window comprises a first profile 2, which rests on a cut-off end face of a second profile 3. The first profile 2 is arranged at a right angle to the second profile 3 with respect to the longitudinal direction of the profiles 2 and 3, but an arrangement at a different angle is also possible.

[0019] The first profile 2 is designed as a hollow profile and has a hollow chamber 20 which is essentially rectangular in cross-section. On an outer side of the first profile 2, on which filling elements, such as insulating glass panes, will later be arranged, grooves 22 are formed for fixing sealing profiles. Between the two grooves 22 there is a screw groove 23, to which pressure strips can be fixed using screws or other fastening means. A drainage channel 24 is provided between the screw groove 23 and the grooves 22. On the groove 22, adjacent to a groove bottom on the side facing away from the groove 22, there is a receptacle 21 which is designed as a closed channel and is provided for inserting a connecting element which is connected to the first profile 2 via first fastening means 7 and to the second profile 3 via second fastening means 8.

[0020] The second profile 3 has the same cross-section as the first profile 2 and comprises a hollow chamber 30 with a substantially rectangular cross-section. On an outer side of the second profile 3, two grooves 32, a screw groove 33, and drainage channels 36 are provided between a groove 32 and the screw groove 33. Receptacles 31 in the form of closed channels are provided at a groove bottom of the groove 32, extending parallel to the longitudinal direction of the second profile 3.

[0021] In Figure 2 The first profile 2 is shown during the assembly of two connectors 4. Each connector 4 is designed as an elongated pin having three openings 40, 41, 42 perpendicular to the longitudinal direction for fastening means 7 or 8. A tool insert 43, for example a slot or Allen key, is formed on one end face of the connecting element 4 to enable the connecting element 4 to be rotated within the receptacle 21.

[0022] Two stops 6 are mounted on the first profile 2, each engaging a receptacle 21. The stops 6 are formed by screws that are screwed into corresponding threaded openings on the groove bottom of the groove 22. By providing a stop within the receptacle 21, a spring element 5, which is formed, for example, as a helical spring or from an elastic material, can be inserted into the receptacle in the next step. Then, a connecting element 4 can be inserted into each receptacle 21, with the spring element 5 being supported on the stop 6 and being compressed when the connecting element 4 is inserted.

[0023] In the Figure 3In the position shown, the connecting elements 4 have been inserted into the receptacles 21 to such an extent that one end face of the connecting elements 4 is arranged substantially flush with one end face of the first profile 2. In this position, the connecting element 4 can be fixed by a fastening means 7, which is designed as a screw and is screwed into one of the openings 40, 41 or 42 in order to fix the connecting element 4 to the first profile 2. In this inserted position of the connecting element, the first profile 2 can be transported to the construction site without the connecting element 4 causing any interference.

[0024] The first profile 2 can be arranged in the assembly position on the construction site, whereby by loosening the fastening means 7 the respective connecting element 4 is released from the transport position and is moved by the force of the adjacent spring element 5 into a protruding position, which in Figure 4is shown.

[0025] In Figure 5the first profile 2 is shown in the assembly position adjacent to the second profile 3. The second profile 3 has two openings 35 on a side wall 34 and a connecting element 4 is inserted into each of the two openings 35. After the connecting element 4 has been inserted, it is fixed by a fastening means 8 in the form of a screw which is screwed into the opening 42 on the protruding section of the connecting element 4. This clamps the connecting element to the second profile 3. In addition, the respective connecting element 4 is fixed to the first profile 2 by further fastening means 7 in the form of screws which are inserted into the opening 40 or 41 on the connecting element 4 so that the first profile 2 is also clamped to the connecting element 4.The connecting element 4 can be made of metal for stable fastening, whereby the openings 40, 41 and 42 can optionally also have an internal thread.

[0026] In Figure 6 The first profile 2 is shown in a transport position, with the groove bottom of the groove 22 partially omitted. It can be seen that the connecting element 4 in the form of the pin is fixed by the fastening means 7 in the form of the screw, and the compressed spring element 5 is arranged between the stop 6 and the connecting element 4. The receptacle 21 has a cross-section that deviates from the circular shape and has a flattened portion to prevent twisting of the connecting element 4, which can optionally be provided with a flattened portion or a slot.

[0027] Figure 7shows the fastening position of the two connecting elements 4, whereby only the left connecting element 4 is fixed to the second profile 3 via a fastening means 8 and to the first profile 2 via a fastening means 7. It can be seen that the connecting elements 4 pass through the opening 35 in the wall 34 of the second profile 3 and extend to a wall 37 of the receptacle 31. The connecting element 4 is fixed by the fastening means 8 in the form of a screw, which passes through a groove bottom of the groove 32 and the opening 42 of the connecting element 4, as shown in the detailed view of the profile 3 on the right.

[0028] In the illustrated embodiment, two connecting elements 4 are mounted spaced apart from one another on the first profile 2, each in a receptacle 21. It is of course also possible to guide only a single connecting element 4 slidably on the first profile 2 in a receptacle 21, for example, on grooves within the first profile 2, which then passes through a slot-shaped opening in the wall 34 of the second profile 3. Optionally, more than two connecting elements 4 can be used for a particularly stable fixation of the T-connection.

[0029] The connecting element 4 is formed in one piece, but can also be assembled from several parts, for example with an expanding connection, for a clamping attachment to the first profile 2 and / or the second profile 3.

[0030] In addition, it is also possible to provide a different number of openings on the connecting element 4 instead of three openings 40, 41 and 42 or to arrange an elongated hole in the connecting element 4, so that when the connecting element 4 is released, the fastening means 7 does not have to be completely dismantled.
