POWER FOR ONE WING

Description

[0001] The invention relates to a drive for a wing, in particular of a door, window or gate, with a drive unit attachable to the wing or a fixed frame, comprising an output shaft which is rotationally fixed to one of the two ends of a sliding arm which is guided at its other end in a sliding rail attachable to the fixed frame or the wing, wherein the drive has a connecting device for connecting conductor elements of electrical components of the drive to externally supplied electrical lines.

[0002] Drives of the type mentioned above generally offer the option of expansion with additional electrical components, such as an electromagnetic hold-open device or an electric hold-open device. To install these additional electrical components, it is necessary to connect the drive's conductor elements to the electrical leads of the additional components to enable their electrical operation. The connection between the drive's conductor elements and the externally supplied leads is typically made using screws or similar fixing devices, with the conductor elements and leads being secured in or to the connecting device, which is located inside the guide rail. Such a device is described in document EP3064694A1.

[0003] However, handling such connection devices, such as terminal blocks, often proves to be impractical or difficult, as the conductors and / or wires can easily slip out of the connection before they are secured. Furthermore, additional tools, such as screwdrivers, are frequently required to secure the wires, which further complicates handling.

[0004] The invention is therefore based on the objective of providing an improved drive of the above-mentioned type, which features a simpler, faster and safer connection of conductor elements of the drive with externally supplied electrical lines.

[0005] This problem is solved by a drive with the features of claim 1, and in particular by the fact that the connecting device comprises a housing, that the housing has an opening through which a housing interior is accessible from the outside, that the housing can be fixed or fixed, in particular detachably, on an outside of the slide rail, and that a clamping device providing a detachable clamping connection is arranged in the housing interior, by means of which the conductor elements can be electrically connected to the externally supplied electrical lines.

[0006] The connecting device allows the drive's conductor elements and externally supplied cables to be connected quickly, easily, conveniently, and securely. Because the housing is mounted on the outside of the guide rail, access is simplified compared to conventional solutions.

[0007] The housing of the connecting device can be made of plastic or metal. The housing can be attached and fixed at any point along the outside of the guide rail. The connecting device is therefore suitable for connecting a wide variety of external electrical components to the drive.

[0008] The flexibility of the application is further increased by the fact that the housing can be detachably fixed to one side of the slide rail. This means that once fixed, the housing can be removed from the slide rail and reattached to a different position along the slide rail, which may be more suitable for the current application.

[0009] The clamping device is located inside the housing and is freely accessible from the outside through the opening of the housing, making it easy and convenient to connect conductor elements and electrical lines.

[0010] Advantageous embodiments of the invention can be found in the dependent claims, the description and the drawing.

[0011] According to one embodiment of the invention, the housing has a U-shaped cross-section. The housing is thus particularly cuboid in shape, with at least one of the side walls being replaced by an opening. Such a housing can be manufactured cost-effectively, and the straight course of its side walls allows for easy attachment to the equally straight outer surfaces of the slide rail.

[0012] According to one embodiment of the invention, the housing can be detachably attached or fixed to a side wall of the slide rail, the side wall extending essentially parallel to a guide surface of the slide rail that runs along the slide rail. The housing can thus be fixed to the front of the slide rail within the installer's field of vision. This has the advantage that the housing, fixed to the slide rail, is easily accessible to the installer, and connecting conductor elements and electrical wires inside the housing can be carried out simply and conveniently.

[0013] According to one embodiment of the invention, the housing has at least one connecting element by means of which the housing can be detachably fixed to the slide rail by means of a snap-fit ​​connection, in particular by clipping the at least one connecting element into a correspondingly designed connecting element on the slide rail. This enables particularly simple and convenient fixing of the housing to the slide rail, and the fixing can be released just as easily and conveniently. The at least one connecting element of the housing can, in particular, be adapted to structural elements already present on the slide rail, which thus form the corresponding connecting elements of the slide rail. It is therefore not necessary to equip the slide rail with additional connecting elements.Rather, it is sufficient to provide at least one connecting element for the housing that is adapted to the existing structural elements of the slide rail. This at least one connecting element of the housing can, for example, be made of plastic and / or be manufactured as a single piece with the housing. To facilitate locking and, in particular, clipping the at least one connecting element onto the slide rail, the connecting element of the housing advantageously possesses a slight flexibility or a certain degree of bending ability, which facilitates its attachment to the connecting element of the slide rail.

[0014] According to one embodiment of the invention, the clamping connection is designed to be manufactured without tools. In other words, the clamping connection can be activated and released without tools or aids, resulting in simple and quick handling of the connection device.

[0015] According to one embodiment of the invention, the clamping device comprises at least one movably arranged, in particular linearly displaceable or pivotable, clamping element, which can be fixed in a position that clamps the conductor elements and the externally supplied cables. By inserting the conductor element and the cable into the clamping device and fixing them in the clamping position, a permanent electrical connection between the conductor element and the cable can be established. The clamping device can be configured such that each clamping element acts on one conductor element or cable individually or separately. Alternatively, the clamping device can be configured such that it acts on all conductor elements and cables simultaneously and / or collectively.This allows all conductor elements and cables to be fixed simultaneously and in one step, which further simplifies the handling of the connection device.

[0016] According to one embodiment of the invention, at least one clamping element is designed as a lever clamp. If several clamping elements are provided in the clamping device, each of the several clamping elements can be designed as a lever clamp. Lever clamps guarantee, firstly, a particularly stable and secure clamping connection of conductor elements and externally supplied cables. Secondly, the clamping connection can be activated and released again without tools or other aids using lever clamps, resulting in simple and quick handling of the connection device.

[0017] According to one embodiment of the invention, the interior of the housing provides a storage space for excess cable sections. These excess cable sections can, for example, be wound up in this storage space to keep them safe. By securely storing the excess sections in this space, it is particularly important to prevent tangles of excess cable from being visible from the outside in the guide rail, thereby also improving the visual appearance of the drive unit.

[0018] According to one embodiment of the invention, the housing has at least one, in particular releasable, fixing element for securing the excess cable sections in the storage compartment. The at least one fixing element can, for example, be designed as a bracket with a film hinge, which extends over the opening of the housing and is pivotable between an open and a closed position, and can be fixed to the housing in the closed position, in particular by snapping. In the closed position, excess cable sections are secured in the storage compartment by the fixing element.

[0019] According to one embodiment of the invention, a cover is provided which covers the slide rail and / or the connecting device fixed to the slide rail. The cover protects the slide rail and the connecting device from dirt, moisture and other external influences and also improves the visual appearance of the drive.

[0020] The invention is explained below only by way of example with reference to the figures.

[0021] Here they show Fig. 1 a schematic representation of an embodiment of a drive 10 according to the invention, Fig. 2A and 2B schematic cross-sectional views of the slide rail of the Fig. 1 with a connecting device fixed to the slide rail, Fig. 3A and 3B perspective views of the slide rail of the Fig. 1 with a connecting device fixed to the slide rail, Fig. 4 a perspective view of an end section of a slide rail covered by a cover with a connecting device fixed to the slide rail, and Fig. 5 a top view of an end face of a slide rail covered with a cover and a connecting device fixed to the slide rail.

[0022] Fig. 1 Figure 1 shows a schematic representation of an embodiment of a drive 10 according to the invention for a leaf 12 of a door, window or gate, with a drive unit 14 attached to the leaf 12 with an output shaft 16, which is non-rotatably connected to one of the two ends of a sliding arm 18, which is guided at its other end in a sliding rail 20 which can be attached to a fixed frame not shown.

[0023] According to the invention, the drive 10 comprises a connecting device 22 (see Fig. 2A und 2B ) for connecting conductor elements of electrical components of the drive 10 to externally supplied electrical lines. The connecting device has a housing 24 (see Fig. 2A und 2B ), which can be detachably fixed to an outer side 26 of the sliding rail 20.

[0024] Fig. 2A und 2B show cross-sectional views of the slide rail 20 of the embodiment of the Fig. 1 The schematic representation shows the fixing of the housing 24 to an outer surface 26 of the slide rail 20. The housing 24 is made of plastic and has a U-shaped cross-section. On the underside 24U of the housing 24, pin-shaped connecting elements 28 are designed such that they can engage with structural elements 20V of the slide rail 20 that protrude from the outer surface 26. To fix the housing 24 to the outer surface 26 of the slide rail 20, as shown in Fig. 2A As shown, the underside 24U of the housing 24 is first placed onto the outer side 26 of the slide rail 20. Then, as shown in Fig. 2B shown, the connecting elements 28 of the housing 24 are engaged with the corresponding connecting elements 20V of the slide rail 20 and the housing 24 is thus detachably fixed by clipping it onto the outside 26 of the slide rail 20.

[0025] According to the embodiment of the Fig. 2A und 2B The housing 24 can be fixed to a side wall 20S of the slide rail 20, which extends essentially parallel to a guide surface 20F of the slide rail 20 that runs along the slide rail 20. The housing 24 is thus fixed in the installer's line of sight in front of the slide rail 20, making it easily accessible. As can be seen, structural elements 20V are also provided on the opposite side wall 20S, so that the housing 24 can also be mounted there, depending on the installation situation.

[0026] Fig. 3A und 3B show perspective views of the slide rail 20 of the Fig. 1 with a connecting device 22 fixed to a side wall 20S of the slide rail 20. As shown in the Fig. 3A und 3B As can be seen, an additional electrical component 30 is attached to a longitudinal end 20E of the slide rail 20, the electrical lines 32 of which are electrically connected to electrical conductor elements 34 of the drive 10 by means of the connecting device 22.

[0027] As previously described, the housing 24 of the connecting device 22 has a U-shaped cross-section, with an opening 36 extending across the entire top of the housing 24 and further lateral openings 38 provided at the two longitudinal ends 24E of the housing 24. In addition, a smaller opening 40 is formed in the underside 24U of the housing 24, which is fixed to the slide rail 20. The interior 42 of the housing 24 is thus accessible from the outside via the top opening 36 and the two lateral openings, and provides access to the side wall 20S of the slide rail 20 via the bottom openings 40.

[0028] A clamping device 44 providing a releasable clamping connection is arranged in the interior of the housing 42. The clamping device 44 comprises several clamping elements 46, which in the illustrated embodiment are each designed as lever clamps.

[0029] To establish an electrical connection between the electrical leads 32 of the additional electrical component 30 and the electrical conductor elements 34 of the drive, the leads 32 and the conductor elements 34 are guided through a lateral opening 38 and the lower opening 40 into the interior of the housing 42 and inserted into one of the lever clamps 46. By actuating or closing the lever clamps 46, the leads 32 and the conductor elements 34 are clamped in the respective lever clamp 46, thus establishing a permanent electrical connection between the leads 32 and the conductor elements 34. The clamping connection can be activated and released without tools or aids using the lever clamps 46, resulting in simple and quick handling of the connection device 22.

[0030] The connecting device 22 allows the externally supplied lines 32 and the conductor elements 34 to be connected quickly, conveniently and safely in an uncomplicated and simple manner.

[0031] The interior of the housing 42 provides a storage compartment 48 for storing excess sections of the cables 32. The excess sections of the cables 32 can, for example, be wound up in the storage compartment 48 to keep them safe.

[0032] To secure the excess sections of the cables 32 in the storage space 48, the housing 24 has two fixing elements 50, which are designed as brackets with film hinges and extend over the upper opening 38 of the housing 20 (see also Fig. 2A und 2B The film hinges 50 can be pivoted between an open and a closed position, whereby the film hinges 50 can be fixed to the housing 24 by latching in the closed position. Fig. 3A und 3B The film hinges are shown in the open and closed positions. By pivoting the film hinges 50 into the closed position, excess sections of the cables 32 (not shown here) are fixed in the storage space 48 and prevented from falling out of the housing 24.

[0033] The drive 10 also has a cover 52, which covers the slide rail 20 and the connecting device 22 fixed to the slide rail 20. The cover 52 is in Fig. 4 The cover 52 is shown in a perspective view. It is attached after the additional electrical component 30 has been installed and connected to the drive 10. The cover 52 protects the guide rail 20 and the connecting device 22 from dirt, moisture, and other external influences, and also improves the visual appearance of the drive 10.

[0034] Fig. 5 shows a top view of an end face of a slide rail 20 covered with a cover 52 and a connecting device 22 fixed to the slide rail 20. The view of the Fig. 5 Figure 1 shows the additional electrical component 30 attached to the longitudinal end 20E of the slide rail 20 together with the housing 24 of the connecting device 22 fixed to a side wall 20S of the slide rail 20. The cover 52 is detachably fixed to the slide rail 20 by means of clipping and is designed such that it covers both the slide rail 20 and the connecting device 22 fixed to the slide rail 20.
