Description

The invention relates to an adapter for at least one strip grid rail of a strip grid ceiling, having a rectangular base, a first side wall which extends at right angles from an edge region of the base, a second side wall which extends at right angles from an edge region of the base, wherein the first side wall and the second side wall are oriented parallel to one another and are arranged on opposite edge regions of the base, and a fastening device which extends from an end-side edge region of the base.Adapters of this type are fundamentally known and serve for fastening a band grid rail to a wall.The fastening device is rigid and rests flat against the wall.The disadvantage of this is that the adapter is suitable only for this special purpose. If, on the other hand, a band-raster rail is to be connected to a further, for example transversely oriented, band-raster rail, a different component is necessary. The differently configured components make assembly more difficult.It is therefore an object of the invention to provide an adapter and a system which is / are versatile in use.This object is achieved by the subject matters of the independent claims.According to the invention, the adapter serves for fastening at least one strip grid rail of a strip grid ceiling, is designed for this purpose and / or can be used for this purpose.The band grid rail is preferably U- or C-shaped. At the ends of the legs a securing edge can be provided. The securing edge serves on the one hand for fastening a ceiling element. Thus, the cover element can be hooked onto the securing edge from the outside. On the other hand, the securing edge serves as a guide and / or upper stop for an adapter inserted into the band-grid notes.The adapter has a rectangular, preferably plate-shaped, base.Preferably, the base has two longitudinal sides and two end sides, wherein the longitudinal sides are longer than the end sides.The adapter has a first side wall which extends at right angles from an edge region, for example a longitudinal side, of the base.Furthermore, the adapter has a second side wall which extends at right angles from an edge region, for example a longitudinal side, of the base.The first side wall and the second side wall are oriented parallel to one another and are arranged at opposite edge regions of the base.The adapter has a fastening device, preferably at least partially at right angles, extending from an end-face edge region of the base.The fastening device is configured in a multifunctional manner for selective fastening to a wall or to a, for example transversely oriented, band grid rail.By means of the selective attachment to a wall or a, for example transversely oriented, band-grid rail, the multifunctional adapter can be used in a versatile manner, so that different components can be dispensed with.Optionally, a third side wall may be provided. This can extend, for example, at right angles to the first side wall and to the second side wall and / or be arranged on an end-face edge region of the base and preferably extend at right angles thereto. The third side wall and the fastening device may be arranged on opposite sides.The third side wall can, for example, increase the stability.Further, the third side wall may be bent downward, for example, if necessary. This increases the size of the base. The adapter is thus versatile in use. For example, the adapter can be used with strip grid rails of different widths.The side walls can preferably have the same height. The fastening device may have the same height or a lower height than the side walls. Thus, the fastening device does not protrude upward.The adapter can preferably be designed as a longitudinal connector for connecting two strip grid rails. Because the fastening device does not protrude upward, the adapter can be inserted into the band grid rails without any problem.The adapter hereby holds via the side walls on the securing edges of the band grid rails.The adapter is preferably designed to be axially symmetrical. The width of the adapter is basically arbitrary. Preferably, the width is adapted to the width of the band grid rail. Thus, the adapter is preferably somewhat narrower than the band-locking rail, so that the adapter can be inserted into the band-locking rail.For example, the adapters can be designed in different widths. The width can be, for example, between 10 cm and 30 cm, for example 10 cm, 12.5 cm or 15 cm.Regardless of the width, the dimensioning of the fastening device can remain the same. Thus, only the distance to the side walls increases, while the central region remains unchanged.The adapter can have or consist of a metal material, e.g. aluminum and / or spring steel, for example.The adapter is preferably formed in one piece.The metal material can be plate-shaped from the home and / or have a uniform thickness. The contour can then be formed, for example bent, beveled, machined, drilled, cut, irradiated, milled and / or lasered in.Further developments of the invention can also be taken from the dependent claims, the description and the accompanying drawings.According to one embodiment, the fastening device has a rigid fastening portion and at least one gripping portion, which is preferably movable relative to the base and / or the fastening portion.The rigid attachment portion preferably extends perpendicular to the base. The fastening section preferably has at least or exactly one hole. Via the hole, the adapter can be screwed, for example, to a wall of a building or to a wall of a transversely oriented band grid rail.It is also possible to provide a plurality of, for example at least or exactly two, three, four or more, holes.The gripping section preferably has a gripping support for placing on a securing edge of a, for example transversely oriented, strip grid rail. The adapter and / or the band grid rail connected to the adapter therefore does not twist.According to a further embodiment, two gripping portions are provided.This further improves the hold on the securing edge of the, for example transversely oriented, band grid rail.According to a further embodiment, the fastening section is arranged between the two gripping sections.This is advantageous from a static point of view. Thus, the adapter can be screwed centrally, for example, on the fastening section. The gripping sections slightly offset laterally thereto counteract an undesired rotation.According to a further embodiment, the gripping portion is arranged flexibly on the base.In order to facilitate the bending, which is preferably carried out by hand, a predetermined bending point can be provided. This can have, for example, one or more holes or a perforation. This is simple and cost-effective to implement on the manufacturing side.Alternatively, for example, a hinge and / or a joint can be provided.According to a further embodiment, the gripping portion is adjustable between a transverse connector holding position and a wall holding position.In the transverse connector holding position, the gripping portion and the fastening portion are preferably arranged in the same plane.Preferably, in the wall holding position, the gripping portion is bent rearward away from the wall. Thus, the gripping portion does not prevent the fastening portion from abutting the wall in a planar manner.According to a further embodiment, the fastening device is spaced apart from the first side wall and / or the second side wall.As a result, sufficient space is available for the securing edge of the band grid rail and / or a cover element fastened thereto.Preferably, the fastening device is arranged centrally and / or tapers upwards. For example, the fastening device can be at least substantially trapezoidal. As a result, the distance from the side walls can be realized in a simple manner.According to a further embodiment, at least one corner of the first side wall and / or of the second side wall is flattened.Preferably, both corners of both side walls are each flattened.The flattened corners facilitate insertion of the adapter into the band grid rail. Thus, the side walls can be threaded under the securing rims in a simple manner.The invention also relates to a system having at least or exactly one adapter according to the invention and at least or exactly one strip grid rail of a strip grid ceiling.Preferably, a plurality of band grid rails are part of the system.Optionally, at least or exactly one cover element can be part of the system.Protection is claimed for both the mounted and the unmounted state.Finally, the invention relates to the use of an adapter according to the invention for fastening a band grid rail of a band grid ceiling to a further, for example transversely oriented, band grid rail and / or a wall, for example a building wall.All aspects, embodiments and features of the invention described here can be combined with one another, preferably also separately from the specific configuration in the context of which they are mentioned. Preferably, all the subjects of the dependent claims can be combined with each other and with each subject of the independent claims.It is generally noted that terms such as "a" or "an" do not necessarily mean "exactly one" or "exactly one", this being likewise possible. The terms "a" and "an" can therefore be understood as "at least or exactly one" or "at least or exactly one". The use of the singular preferably includes the presence of the plural components and vice versa.It is noted that "preferably" and "preferably" may be translated as "preferably" to English. A feature introduced by "preferably" or "preferably" is purely optional, may be omitted and does not represent a limitation, for example of the claims.The invention is described below by way of example with reference to the drawings.
