Description

[0001] The invention relates to a connecting angle for creating a connection between two groove profiles, with two surfaces perpendicular to each other, each of which has a receiving opening for passing a fastening means.

[0002] Connecting brackets are known in which two grooved profiles are fastened together by means of a fastener. Document DE 10 2020 117 657 A1 describes such a connecting bracket. The connecting bracket comprises a receptacle and an insert containing a movable fastener. This fastener is designed to engage in a receiving opening of the grooved profile. The head of a hammerhead bolt can be pushed through the receiving opening and then abuts against the receptacle. In this way, the hammerhead bolt can be installed or removed through the bracket while the bracket is in position and, if necessary, also secured on one side.

[0003] In the field of joining technology for T-slot profiles, it is common to use connecting brackets to ensure stable and precise connections between two profiles. Well-known systems typically include simple angle brackets that are attached to the profiles using screws or other fasteners. These conventional connecting brackets are often made of metal or plastic and offer a certain degree of stability and strength. However, they also have some disadvantages; for example, the installation of such connecting brackets can be time-consuming and complicated, especially when multiple fastening points are required.

[0004] Furthermore, the problem with common connecting angles is that they can only be used on grooved profiles with a specific cross-section.

[0005] One object of the present invention is to provide a connecting bracket for creating a connection between two groove profiles, which is particularly versatile for use with groove profiles of different widths. Furthermore, the connecting bracket should be mountable in two mutually perpendicular positions.

[0006] According to the present disclosure, these problems are solved by the features of independent claim 1. Furthermore, additional advantageous embodiments are described in the dependent claims and the description.

[0007] A connecting angle is provided for creating a connection between two groove profiles, with two mutually perpendicular surfaces, each of which has a receiving opening for the insertion of a fastening element. According to the invention, the surfaces are assigned back sides with surfaces, each of which has an insert structure with an inserted rubber profile, wherein the rubber profile has movable lips for fitting into a groove of the groove profile, which are bent upwards away from the surfaces under preload.

[0008] The connecting bracket consists of two perpendicular surfaces, each with a receiving opening for a fastener. This arrangement allows for a precise and secure connection of the groove profiles. Both surfaces of the connecting bracket have profiled backs, creating an insertable structure to which a rubber profile can be attached. The connecting bracket is fastened to the groove profile using a fastener. The lips serve to secure the connecting bracket to the groove profile. They engage with the groove profile, ensuring a slip-resistant connection.

[0009] The reverse sides of the surfaces can be equipped with two lateral channels, a central insertion channel running parallel to the lateral channels, and a transverse connecting channel linking the two lateral channels. A cross-shaped rubber profile with two bars arranged at a 90° angle can be installed at the intersection of the insertion channel and the connecting channel. A transverse connecting channel can link the two lateral channels. A cross-shaped rubber profile consisting of two bars arranged at a 90° angle to each other can also be installed at the intersection of the insertion channel and the connecting channel. The receiving opening for the fastener can be located at the intersection of the insertion channel and the connecting channel.

[0010] In one embodiment, the lips are fixed to the ends of the profiles. The preload on the lips causes them to engage with the aluminum profiles and be secured there. Furthermore, the upward bending of the lips allows for better adaptation and flexibility during the assembly of the grooved profiles. The lips can easily adapt to different tolerances and deviations in the profiles.

[0011] According to another embodiment, the ends of the beams of the cross-shaped rubber profile are equipped with extensions. These extensions play a crucial role in the mechanical interaction between the components of the connecting angle. Two of the extensions are inserted into the lateral channels, meaning they are housed within these channels and do not interfere with assembly. Their surface ensures a secure anchorage within the structure of the connecting angle. This arrangement also ensures that the rubber profile is held securely in the channels and cannot slip, thus increasing the stability of the entire connection. The other two extensions rest on the surfaces on either side of the insertion channel and can engage in the groove of the grooved profile.The extensions act as anchor points, stabilizing the rubber profile and preventing it from deforming or shifting under load. Furthermore, the extensions facilitate the installation of the connecting angle, as they allow for precise positioning of the rubber profile and ensure that it sits correctly in the channels and on the surfaces.

[0012] The insert structure can each have two parallel insert channels and a connecting channel running perpendicular to the two parallel insert channels, wherein the connecting channel connects the two lower ends of the parallel insert channels together and wherein the rubber profile, which is U-shaped, is installed in the insert structure when used as intended.

[0013] According to another embodiment, the U-shaped rubber profile can have lips for engaging with a groove in the groove profile. These lips improve the fixation of the rubber profile in the grooves by creating a mechanical lock that securely holds the profile in position. This prevents lateral slippage of the rubber profile, especially under load. Furthermore, the specific shape of the lips allows for quick and easy installation of the rubber profile, as the lips act as guides and facilitate positioning relative to the groove. This reduces installation effort and minimizes the risk of installation errors. Overall, the lips contribute to improving the functionality, reliability, and durability of the connection between the groove profiles by ensuring secure fixation, easy installation, and optimized force distribution.

[0014] According to another embodiment, the rubber profile has a through-opening. When properly positioned, this through-opening aligns with the receiving opening. This means that the through-opening of the rubber profile and the receiving opening are in a straight line when the rubber profile is correctly positioned at the intersection. The through-opening in the rubber profile allows for a direct and unobstructed connection between the fastener and the receiving opening.

[0015] Furthermore, the connecting angle for creating a connection between two groove profiles can have a side surface that is arranged at a 90° angle to the two mutually perpendicular surfaces. The free edge, together with the widely separated edges of the two surfaces, forms an access opening to the enclosed space.

[0016] Preferably, a cover can be arranged on the connecting angle, contacting the edges of the access opening. The cover prevents dirt, dust, or other foreign matter from entering the access opening. Furthermore, the cover contributes to the aesthetic improvement of the connecting angle by creating a smooth and uniform surface, thus enhancing the overall appearance of the connecting angle. The cover can be made from various materials, selected according to the specific requirements of the application. For example, the cover could be made of a flexible plastic or a robust metal.

[0017] According to another embodiment, the cover has a slot. The slot in the cover allows for improved accessibility and flexibility during the assembly and disassembly of the connecting bracket. The slot makes it easier to position the cover over the fasteners and the receiving opening, resulting in simpler handling and faster installation. Furthermore, a tool can be used to grip the cover and lift it.

[0018] According to a further embodiment, the connecting bracket for creating a connection between two T-slot profiles includes a fastener designed as a hammerhead screw. A hammerhead screw is designed such that its head has a flat, wide shape, allowing it to be inserted into a slot and locked by a turning motion. This mechanism of communication between the hammerhead screw and the slot of the profile ensures a firm and secure connection that is easy to make but not easily loosened. In particular, it is advantageous that such a hammerhead screw does not have to be threaded into the T-slot profile from the end face, as is the case with conventional T-nuts, but can be inserted laterally into the slot at any desired point. The hammerhead screw is inserted into the connecting bracket through the receiving opening and secured there with a nut as a counterpart.A pre-prepared angle is placed on the groove profiles to be joined in such a way that the head of the hammerhead screw lies in the groove and is anchored in the groove of the profile by a turning movement.

[0019] According to one embodiment, screw sleeves for fixing the hammerhead screws can be aligned with the receiving openings.

[0020] The invention described above will be explained in more detail below using an exemplary embodiment.

[0021] They show Fig. 1 An embodiment of a connecting angle with an inserted cross-shaped rubber profile in a view from below. Fig. 2 a cross-shaped rubber profile according to the embodiment in Fig. 1 both in side view and in top view, as well as Fig. 3 another embodiment of a connecting angle for creating a connection between two groove profiles, Fig. 4 an exploded view of a connecting angle according to Fig. 3 with various components, including a cover, a hammerhead screw and a U-shaped rubber profile, Fig. 5 an embodiment according to Fig. 3 or Fig. 4 of a U-shaped rubber profile both in side view and in an oblique view, as well as Fig. 6 a connecting angle according to the Fig. 3 to 5 with inserted rubber profile in a view from below.

[0022] Fig. Figure 1 shows a perspective view of the connecting angle in which the rubber profile 12 is integrated. The connecting angle consists of two mutually perpendicular surfaces 3, each with a receiving opening 4 for the insertion of a fastening element 5. Rear faces are assigned to the surfaces 3, each featuring two lateral channels 8, a central insertion channel 9 running parallel to the lateral channels, and a transverse connecting channel 10 linking the two lateral channels 8. The cross-shaped rubber profile 12 is attached at the intersection 11 between the insertion channel 9 and the connecting channel 10. The beams 24 and the lips 13 of the rubber profile 12 are bent upwards towards their ends away from the surfaces 3 under pre-tension. The extensions of the beams 24 are positioned such that two are inserted into the lateral channels 8 and the other two rest on the surfaces 3 on either side of the insertion channel 9.The lips 13 at the ends of the beams 24 ensure that the rubber profile 12 is securely nestled into the groove of the groove profile 2.

[0023] The connecting angle 1 is designed to provide a stable connection between two groove profiles 2. The lateral channels 8 and the insertion channel 9 ensure precise positioning of the rubber profile 12, while the connecting channel 10 facilitates the integration of the various components. The receiving opening 4 in the intersection 11 allows the insertion of a fastener 5, such as a hammerhead screw 21, to secure the connection.

[0024] Fig. Figure 2 shows a schematic representation of a cross-shaped rubber profile 12 used in a connecting angle. The rubber profile 12 consists of two beams 24 arranged at a 90° angle to each other. These beams 24 have widened ends. The widened ends are designed to fit into the lateral channels of the connecting angle. Additionally, the ends of the beams 24 are provided with a lip 13, which allows the rubber profile 12 to fit into a groove of the grooved profile 2. In the central area of ​​the rubber profile 12, there is a through-opening 23, which, when properly positioned on the intersection, aligns with the receiving opening.

[0025] The representation in Fig. Figure 3 illustrates the spatial arrangement and functional integration of the various components of the connecting angle. The groove profiles 2 are connected in such a way that the surfaces 3 of the connecting angle ensure stable and precise alignment. A cover 19, which can contact the access opening 18, contributes, if necessary, to the functional completeness of the connecting angle by covering the edges 17 and forming a clean finish, as shown in Figure 3. Fig. 3 indicated.

[0026] The slot 20 in the cover 19 allows for easy and secure attachment of the connecting angle to the groove profiles 2.

[0027] Fig. Figure 4 shows an exploded view of a connecting angle according to Fig. 3 with various components, including a cover 19, a hammerhead screw 21, and a U-shaped rubber profile 12, in side view. U-shaped rubber profiles 12 are fastened to the surfaces 3 by means of hammerhead screws 21 and screw sleeves 22. The free edges 17 of the side surfaces 16 enclose a space with the surfaces 3. The cover 19 contacts this free space.

[0028] In Fig. Figure 4 shows a U-shaped rubber profile 12 in a side view as well as in an oblique view. A through-opening 23 in the form of a slot is visible. When the rubber profile 12 is properly positioned on the surfaces 3, the through-opening 23 aligns with the receiving opening 4, allowing a fastening element 5 to be inserted through both openings 4 and 23 to secure the rubber profile 12. Furthermore, movable lips 13 are arranged on the rubber profile 12, which serve to secure the rubber profile 12 to the groove profile 2. When properly positioned, the lips 13 conform to the groove profiles 2 and prevent the rubber profile 12 from slipping.

[0029] Fig.Figure 6 shows a U-shaped rubber profile attached to a connecting bracket. The surfaces 3 of the connecting bracket have corresponding back faces, which have profiled surfaces 6. The profiling of the surfaces 6 creates an insert structure 7 into which the U-shaped rubber profile 12 can be inserted. The insert structure 7 has two parallel insertion channels 14 and a connecting channel 15 running perpendicular to the two parallel insertion channels 14. The connecting channel 15 also connects the two lower ends of the parallel insertion channels 14.

[0030] The above describes a connecting bracket for creating a connection between two grooved profiles, which is particularly versatile for use with grooved profiles of different widths. Furthermore, the connecting bracket can be mounted in two mutually perpendicular positions.
