Description

Field of the InventionThe present invention relates to a holder for mechanical and / or electronic or electrical devices having the features according to claim 1 and to a fastening means having the features according to claim 13.In this case, basically all that is to be held on fastening means by such holders is considered as a mechanical and / or electronic or electrical device. Conceivable are, for example, hooks, hangers, connection elements, cameras, radio devices and the like.Prior ArtConventional holders often consist of several parts, which are expensive to manufacture and assemble. Due to the multi-part nature, they are often also prone to errors and awkward to operate. In particular, the connection to a fastening means such as a suction cup is usually not unproblematic in practice, since a stable connection between the holder and the fastening means is important in order to prevent unintentional detachment of the holder, in particular of the mechanical and / or electronic or electrical device connected thereto, from the fastening means. This is often achieved by means of a complex and complex mechanism, which is also intended to prevent a relative movement between the holder and the fastening means.Such a suction cup is known as a suction device, for example from EP 3 855 031 A1. It has a first region which serves for the actuation of the suction device and a second region which can be brought into contact with a substrate surface via a suction cup surface. The first region consists of a harder first material and the second region consists of a second material which is softer with respect to the first material, wherein the second material is an ultraplastic material having a shore hardness of less than 50. The thickness of the second region in an unloaded state is at least 2.5% of an outer diameter or a length or width of the first region and / or particles and / or fibers are integrated into the second material that are harder than the second material. The suction cup presented can be used on very rough and wavy surfaces and also under water. Preferably, on the side opposite the suction cup, it has a holding element for attaching a holder.SUMMARY OF THE INVENTIONThe object of the invention is to specify a holder and a fastening means which can be connected to one another in a simple and reliable manner and prevent unintentional detachment from one another and a movement relative to one another.SUMMARY OF THE INVENTIONThis is achieved with a holder according to the features of claim 1. The holder has a plurality of interconnected part holders which can be pushed radially on a second axial end of a coupling part via the coupling part. The partial holders have on their inner sides preferably radially protruding connecting webs which, in the pushed-on state, engage in at least one preferably radially arranged recess of the coupling part. The partial holders also form, in a connected state, at least one shell-shaped holder body which, in the pushed-on state, surrounds the coupling part at the second axial end with an inner side at least partially and / or in sections, preferably completely.The object is also achieved with a fastening means according to the features of claim 13. The coupling part has at least one preferably radially arranged recess which, in the state connected to the holder, accommodates connecting webs which preferably project radially from an inner side of a shell-shaped holder body of the holder. In the connected state, the shell-shaped holder body of the holder furthermore encloses the coupling part at the second axial end with the inner side of the shell-shaped holder body at least partially and / or in sections, preferably completely.Advantageously, simple mounting of the holder on the coupling part is possible in that no tool is necessary for this purpose, but only the partial holders have to be pushed onto the coupling part for this purpose. Sliding apart of the partial holders is avoided by the engagement of the connecting webs of the partial holders in the recesses of the coupling part. Likewise, a secure connection between the holder and the coupling part is achieved as a result. Due to the friction or, in the case of a corresponding material of the coupling part and the partial holders, also due to adhesion, the connection between them is further improved. In the case of a connection of the coupling part to the fastening means, in particular a suction cup, which can optionally be made in one piece, the fastening means and the coupling part can be formed from a rubber-like plastic, which enables good adhesion between the coupling part and the holder. At the same time, the engagement of the connecting webs in the recesses prevents a relative rotation of the coupling part and the partial holders or of the shell-shaped holder body formed by the partial holders.Advantageous further developments are the subject matter of the dependent claims. The features individually listed in the claims can be combined with one another in a technically meaningful manner and can be supplemented by explanatory facts from the description and by details from the figures, wherein further embodiment variants of the invention are shown.In a preferred embodiment which advantageously improves the stability of the connection of the holder and the coupling part, the partial holders have internal radial projections which, in a state pushed onto the coupling part, engage in at least one first circumferential radial groove of the coupling part. As a result, the connection strength in the axial direction of the coupling part is increased.In a preferred embodiment which advantageously improves the stability of the connection of the holder and the coupling part, the radially protruding connecting webs protrude from the inner projections of the partial holders. The at least one first circumferential radial groove of the coupling part and the radial projections engaging therein can be arranged geometrically centrally, whereby the stability of the connection is further improved in conjunction with the radially protruding connecting webs engaging in the at least one radial recess.In a preferred embodiment which advantageously improves the design and adaptation capability of the holder and of the coupling part and the stability of the connection of the holder and of the coupling part, the at least one holder body has an inner shape which is round, oval or polygonal at least in the radial direction and corresponds to an outer shape of the coupling part. The outer shape of the holder can be adapted to the inner shape in order to achieve a shape of the holder that is individual for the intended use. The outer shape can, however, also be independent of the inner shape. However, the inner shape of the holder can also additionally improve the stability of the connection with respect to a relative movement of the holder and the coupling part with respect to one another.In a preferred embodiment advantageously facilitating the connection of the holder to a mechanical and / or electronic or electrical device, the at least one shell-shaped holder body has at least one connecting piece on a shell outer side of at least one partial holder for connection to the mechanical and / or electronic or electrical device. The adaptation of the mechanical and / or electronic or electrical device to the holder is thereby substantially facilitated.In a preferred embodiment which advantageously further facilitates the connection of the holder to a mechanical and / or electronic or electrical device, the at least one connecting piece of the at least one shell-shaped holder body has a tab-shaped form with a first aperture. A corresponding counter piece can easily be placed on the tab-shaped connecting piece and fastened by means of the first aperture, for example via a screw connection.In a preferred embodiment advantageously facilitating the connection of the holder to a mechanical and / or electronic or electrical device, a plurality of connecting pieces are arranged parallel spaced apart from one another. This arrangement of the connecting pieces opens up the possibility of frictionally engaging connection with connecting pieces of the mechanical and / or electronic or electrical device which are likewise spaced apart in parallel. These can be easily pushed into one another, which already clearly improves the stability of the connection.In a preferred embodiment advantageously facilitating the connection of the holder to a mechanical and / or electronic or electrical device, a hexagonal nut or a recess corresponding to the shape of the nut is integrally formed on the at least one connecting piece around the first opening. In the case of a screw connection, a separate nut can be dispensed with by this measure and the screw can easily be screwed into the nut which is fixed as a result.In a preferred embodiment which advantageously improves the stability of the connection of the holder and the coupling part, the partial holders have pin / pin hole connections on their connection sides. This further increases the stability of the connection already provided by frictional engagement or adhesion and additionally counteracts slipping apart of the partial holders.In a preferred embodiment which advantageously improves the transport of the holder and optionally of the coupling part connected thereto and of the device connected to the coupling part, the at least one shell-shaped holder body has at least one second aperture on a shell outer side, to which aperture a carrying loop can be fastened.In a preferred embodiment which advantageously improves the stability of the connection of the holder and the coupling part, the at least one shell-shaped holder body has at least one second circumferential radial groove on an outer shell side, into which groove an O-ring can be inserted, which additionally presses the partial holders together.In a preferred embodiment which advantageously extends the possible uses, the holder, in the connected state of the partial holders, has two shell-shaped holder bodies which are connected to one another and are arranged symmetrically mirrored with respect to one another and can be connected simultaneously to two coupling parts. One of the coupling parts can be connected to a fastening means such as a suction cup, whereas the other coupling part is connected to a mechanical and / or electronic or electrical device. Alternatively, both coupling parts can also be connected to a fastening means such as a suction cup, and a mechanical and / or electronic or electrical device is optionally connected to the holder by means of at least one connecting piece.In a preferred embodiment which advantageously improves the design and adaptation capability of the holder and of the coupling part and the stability of the connection of the holder and of the coupling part, the holder is made of plastic or metal. Depending on the nature of the surface of the holder, the frictional engagement and / or the adhesion between the material of the holder and the material of the coupling part is thereby increased.In a preferred embodiment which advantageously improves the stability of the connection of the fastening means and the holder, the coupling part has at least one first encircling radial groove which, in a connected state of the fastening means to the holder, accommodates radial projections arranged on an inner side of a cup-shaped holder body. As a result, the connection strength in the axial direction of the coupling part is increased once more.In a preferred embodiment which advantageously simplifies the fastening of the holder, the fastening means is a suction cup which enables a screw-free connection.The invention will now be explained in more detail with reference to an exemplary embodiment. The following are shown: FIG. 1 shows a perspective view of a first embodiment of a holder and a fastening means, FIG. 2 is a perspective view of the underside of the first embodiment, FIG. 3 shows a perspective view of the first embodiment of the holder with the fastening means connected thereto, FIG. 4 is a sectional view of the first embodiment according to FIG. 3 , FIG. 5 shows a perspective view of a second embodiment of the holder and of the fastening means, FIG. 6 shows a perspective view of the second embodiment of the holder with the fastening means connected thereto, FIG. 7 is a perspective view of a third embodiment of the holder.DESCRIPTION OF PREFERRED EMBODIMENTSBefore describing the invention in detail, it should be noted that it is not limited to the respective components of the device according to the invention as well as the respective method steps, since these components and methods can vary. The terms used herein are intended to describe particular embodiments only and are not used in a limiting sense. Moreover, when the singular or indefinite articles are used in the specification or claims, this also refers to the plurality of these elements unless the overall context clearly indicates otherwise.FIGS. 1 to 4 show a first embodiment of a holder 10 according to the invention for mechanical and / or electronic or electrical devices, such as a camera, for example, which can be connected to at least one fastening means 170, wherein the at least one fastening means 170 has a coupling part 20 which is connected by a first axial end 22 either integrally to the at least one fastening means 170 or can be connected thereto. The fastening means 170 can be configured, for example, as a suction device, such as a suction cup.The holder 10 comprises a plurality of interconnected part holders 40 which can be pushed radially on over the coupling part 20 at a second axial end 24 of the coupling part 20. In the specific exemplary embodiment, these partial holders form two half shells which enclose the coupling part 20, which is round in the exemplary embodiment, with an angular range of 180°. In principle, however, it is also possible to provide more than two partial holders 40 for forming the holder, which also have a different angle, preferably also less than 180°. In addition, it is also possible for the partial holders 40 not to enclose the coupling part 20 completely or over the entire circumference, but only partially or also only in sections. The coupling part 20 can also have any other shape as long as the partial holders are to be fastened thereto.Preferably, the partial holders 40 have on their inner sides preferably radially protruding connecting webs 60 which, in a state pushed onto the coupling part 20, engage in at least one preferably radially arranged recess 70 of the coupling part 20. As can be seen in FIG. 3, the partial holders 40 form, in a connected state, at least one shell-shaped holder body 80 which, in the pushed-on state, surrounds the coupling part 20 at the second axial end 24 with an inner side at least partially and / or in sections, preferably completely. In this case, the connecting webs produce a reinforced positive connection between the coupling part 20 and the part holders 40.For the strength of the connection in the axial direction, the partial holders 40 preferably have inner radial projections 50 which, in a state pushed onto the coupling part 20, engage in at least one first circumferential radial groove 30 of the coupling part 20. This likewise represents a positive connection between coupling part 20 and partial holders 40.In an embodiment which further increases the stability of the connection, the radially protruding connecting webs 60 preferably protrude from the inner radial projections 50 of the partial holders 40. The projections 50 and the connecting webs 60 can be arranged centrally, just like the first encircling radial groove 30 of the coupling part 20, in order to ensure optimum force transmission.The at least one shell-shaped holding body 80 can advantageously have at least one inner shape that is round, oval or polygonal in the radial direction and corresponds to an outer shape of the coupling part 20 or is adapted thereto. This advantageously increases the resistance to rotation between the holder 10 and the coupling part 20 on the one hand and also opens up design possibilities on the other hand, in that, for example, the outer shape of the holder 10 can be adapted to its inner shape or deviates therefrom.The at least one shell-shaped holder body 80 can advantageously have at least one connecting piece 90 on a shell outer side of at least one partial holder 40 for connection to and / or for connection of a mechanical and / or electronic or electrical device. The mechanical and / or electronic or electrical device can be attached to this connecting piece 90, for example, either directly or by means of an adapter.The at least one connecting piece 90 can preferably have a tab-shaped form with a first through opening 100. For example, either a further tab-shaped connecting part of the mechanical and / or electronic or electrical device or an adapter can be placed directly on this tab and connected to the at least one connecting piece 90 by means of a screw connection. In principle, a connection of a preferably diametrically opposed holding body is also possible.The strength of the connection can advantageously be increased by arranging a plurality of connecting pieces 90 at a distance from one another in parallel. In this case, for example, the further tab-shaped connecting part can be inserted between two connecting pieces 90, preferably by friction locking, and optionally additionally screwed.A screw connection is advantageously facilitated if a hexagonal nut 110 or a recess corresponding to the shape of the nut according to FIGS. 3, 4 is preferably formed on the at least one connecting piece 90 around the first opening 100. This eliminates fixation of the nut while a screw is being screwed in.If the partial holders 40 have pin 120 / pin hole 130 connections according to FIGS. 1, 2, 7 on their connecting sides, the strength or stability of the connection between the partial holders 40 can thereby be advantageously increased. Optionally, the pins 120 may also snap into the pin holes 130.For transporting the holder 10 and the fastening means 170 optionally connected thereto, the at least one shell-shaped holder body 80 can advantageously have at least one second aperture 140 according to FIGS. 1, 3 on a shell outer side, said second aperture being designed for fastening a carrying loop.The stability or strength of the connection of the interconnected partial holders 40 can preferably be increased by the at least one shell-shaped holder body 80 having at least one second circumferential radial groove 150 according to the second exemplary embodiment of the holder 10 according to FIGS. 5, 6 on a shell outer side, which groove is designed to receive an O-ring 160. The O-ring 160 presses the partial holders 40 together on the one hand and securely prevents the partial holders 40..It is also possible that the holder 10 in the connected state of the partial holders 40 has two shell-shaped holder bodies 80 connected to one another, which are arranged symmetrically mirrored with respect to one another and at the same time can be connected to two coupling parts 20 at axially opposite ends. In FIG. 7, this third embodiment of the holder 10 is illustrated. As a result, for example, the holder 10 can be arranged between two fastening means 170, such as, for example, suction cups or solid structures. If appropriate, a mechanical and / or electronic or electrical device can be arranged on the holder, for example by means of at least one connecting piece 90. However, the holder 10 can also be fastened to a solid structure only on one side by means of a suction cup and a mechanical and / or electronic or electrical device can be fastened to a corresponding fastening means 170 on the other side of the holder 10.In order to advantageously increase the connection strength between the holder 10 and the fastening means 170, in particular the coupling part 20, the holder 10 can preferably be made of plastic or metal. As a result, their material properties can be coordinated with one another in a targeted manner with respect to an optimized friction and / or adhesion force. In particular, if the fastening means 170 is a suction cup, which has, for example, a coupling part 20 formed integrally on and is made of a rubber-like material specially created for this purpose, the connection to a holder 10 made of plastic or metal is advantageous. In this case, a frictional connection between the materials can be achieved, which also makes radial removal of the partial holders 40 from the coupling part 20 more difficult.Part of the invention is also a fastening means 170 which has a coupling part 20 and can be connected to a holder 10 as described above, wherein the fastening means 170 is either connected or can be connected in one piece to a first axial end 22 of a coupling part 20. The coupling part 20 has at least one radially arranged recess 70 which, in the state connected to the holder 10, accommodates connecting webs 60 projecting radially from an inner side of a shell-shaped holder body 80 of the holder 10. The shell-shaped holder body 80 of the holder 10 is designed in the connected state to enclose the coupling part 20 at the second axial end 24 with the inner side at least partially, preferably completely.In a manner advantageous for the strength of the connection in the axial direction, the coupling part 20 has at least one first circumferential radial groove 30, which, in the connected state of the fastening means 170 with the holder 10, accommodates radial projections 50 arranged on the inner side of the cup-shaped holder body 80 of the holder 10.For the fastening of the holder 10, it is particularly advantageous if the fastening means 170 is a suction cup. This permits simple mounting of the holder 10 on surfaces compatible therewith without bores or screw connections.List of reference characters10 Holding device, 20 coupling part, 22 first axial end of the coupling part, 24 second axial end of the coupling part, 30 first encircling radial groove, 40 partial holding device, 50 internal protrusion, 60 radially protruding connecting web, 70 radially arranged recess, 80 cup-shaped holding body, 90 connecting piece, 100 first aperture, 110 hexagonal nut or corresponding recess, 120 pin, 130 pin hole, 140 second aperture, 150 second encircling radial groove, 160 O-ring, 170 fastening means.References included in the specificationThis list of documents cited by the applicant has been produced in an automated manner and is only included for the better information of the reader.
