Document US 9972984B 1 discloses a device for arranging cables.

Disclosure of Invention

On this background, it is an object of the invention to provide a deformable fastening solution for cables.

This object is achieved by a fastening strip and a method having the features of the independent claims. Embodiments of the fastening strip and the method result from the dependent claims.

The fastening strip according to the invention is designed and provided for elongate components and has a plurality of, for example, solid and/or rigid carrier pieces for receiving the components, which carrier pieces are arranged one after the other, for example along a row. In this case, two directly adjacent carrier elements are connected to one another by, for example, a flexible and/or elastically deformable film hinge.

Since the carrier elements are connected to one another by flexible and/or elastically deformable film hinges, the fastening strips and/or the corresponding holding strips are also flexible and/or elastically deformable. The fastening strips can be arranged on and/or on differently shaped components, wherein the fastening strips can be adapted to the shape or contour of the component accordingly. The fastening strip can be used, for example, for a vehicle, in particular a motor vehicle or a motor vehicle. Typically, the component or assembly to which the elongate member is to be secured has a shape and/or surface that is different from a flat and/or planar shape. The fastening strip can also be used here to fasten elongate components to uneven and/or non-flat components or parts. The fastening strips have a chain/string of a plurality of carrier elements connected to each other via film hinges, which carrier elements can be moved relative to each other, whereby the fastening strips can be matched to the contour of the respective component.

Here, each carrier piece or piece has a receptacle, for example a clip, a clamping element or a clamp, for receiving a respective section of the elongated member or the elongated pipeline element. As a whole, the component is received by receivers in carrier parts connected to one another along a row, wherein the respective sections of the component can be snapped and/or clipped into the receivers and thus received therein. In this case, each carrier part of the fastening strip can be moved relative to any other carrier part.

In an embodiment, the fastening strip is used to receive an elongate electrical component or line element, for example designed as a cable, line or hose. In general, the component that can be or is to be received by the fastening strip has a cross section that can be designed as a circle or as an n-angle/polygon, wherein the component can extend perpendicular to this cross section along, for example, the longitudinal center axis. The component to be received can also be elastically deformable.

A first method according to the invention is designed for manufacturing a fastening or holding strip for an elongated member. The fastening strip produced by the first method has a plurality of carrier parts for receiving components, which are arranged one behind the other in a row, wherein each two directly adjacent carrier parts are connected to each other by a film hinge.

In this case, the carrier part and the film hinge of the fastening strip can be produced completely from the one-piece/continuous body/element by means of an injection mold for producing at least one part or at least one section of the fastening strip. The fastening strips can be produced here as an approximately unlimited number of goods sold in metres, from which chains of, for example, sections of the desired length or carrier elements connected to one another are separated, for example cut out.

Furthermore, as an alternative or in addition, a film hinge can be injection-molded onto each of two directly adjacently arranged carrier parts in order to produce at least one part or at least one section of the fastening strip. In this case, a film hinge is arranged between each two carrier parts. For example, two sections or chains from the two actual fastening strips can be connected to one another, and thus a longer fastening strip is formed, wherein the two carrier parts, each at one end of the respective actual fastening strip, are connected by a film hinge, which is arranged, for example, fastened, on the two carrier parts. The fastening strip can be designed or lengthened flexibly, for example lengthened or shortened, depending on its length requirement.

The second method according to the invention is designed for fastening an elongated member at and/or on a surface of a component. Here, using one embodiment of the fastening strip according to the invention, the fastening strip according to the invention is manufactured by an embodiment of the first method for manufacturing a fastening strip according to the invention.

In this case, the carrier elements or carriers respectively receive the respective sections of the elongate members, so that each section is clipped and/or clamped into the receiver of the respective carrier element. Each receiving element has a groove, which is delimited by two groove walls, for example two feet or arms. Alternatively or additionally, the elongate member may be threaded into the receivers of a plurality of carrier elements arranged one after the other along the fastening strip. In this case, the receiver may also enclose a slot for receiving a section of the elongate member. Alternatively, it is also conceivable for the receiving element to enclose a tunnel-like opening into which the component is inserted, i.e. for the receiving element to be designed in the form of an eyelet.

It is furthermore possible to fasten the carrier elements or at least some of the carrier elements, usually each carrier element, to a surface of the component. The carrier element can be fixedly bonded to the surface by at least one adhesive element. In this case, the adhesive surface of the at least one adhesive element can be arranged on the side of the carrier element that is to be fastened to the surface, while a receiver for receiving the component is arranged on the other side of the carrier element facing away from this side. Since the carrier elements can be moved relative to one another, the fastening strips can be adapted to the contour and shape of the component.

Embodiments utilizing the first method provide a flexible and, for example, shape adaptable fastening strip for electronic wires and other electronic components.

Possible applications of the fastening strip and the method are provided in the manufacture of motor vehicles. A sensor-controlled trunk lid is therefore installed in some high-end vehicles, providing additional convenience to the user when opening the trunk lid. Here, this opening is triggered by an air Kick (Luft-sock) under the rear bumper and/or rear apron. In order to be able to detect this kicking in the air, two coaxial lines are installed, for example, in the fascia of the bumper. Each coaxial wire is secured in the diffuser or trim plate by a special retaining device. Since very high installation differences can occur here, this involves high investment, development and testing costs.

In contrast, the fastening strip proposed here can be adapted to any shaped component, for example a component of a motor vehicle, and fastened thereto. Thus, the die and development costs can be saved. Due to the scale effect, the price of a single part is lower when manufacturing the fastening strips.

The entire fastening strip can also be produced from or in a single injection mold. The individual carrier parts are connected to one another here by a film hinge which is released (Werkzeugfallend), i.e. the film hinge can be easily released from the mold of the injection mold and removed therefrom. In this case, it is not necessary to subsequently connect or assemble the carrier elements to one another. Regardless of how the individual sections of the fastening strip are manufactured, the elongate member can be inserted into the receptacle of the carrier element and clipped and/or clamped with the receptacle in the receptacle.

It goes without saying that the features mentioned above and those yet to be described below can be used not only in the respectively mentioned combination but also in other combinations or alone without departing from the scope of the invention.

Drawings

The invention is schematically illustrated in the drawings according to embodiments and described in detail with reference to the drawings.

Fig. 1 shows a schematic view of an embodiment of a fastening strip according to the invention.

The description of the figures is generalized and associated, with like reference numerals being assigned to like components.

Detailed Description

Fig. 1a, 1b and 1c show schematically embodiments of a fastening strip 2 according to the invention in different states of bending or bending to different extents, which fastening strip is also referred to and/or designed as a retaining strip. Fig. 1d and 1e show an enlarged detail of the fastening strip 2.

The fastening strip 2 has a plurality of carrier parts 4, wherein each two directly adjacent carrier parts 4 are connected to one another by a flexible and/or elastically deformable film hinge 6. Each carrier element 4 has a receiving means 8 on its upper side and an adhesive means 10 on the lower side opposite the upper side.

Each receiving part 8 comprises two groove walls 14, 16 arranged next to one another, between which there is a groove, which is delimited by the two groove walls 14, 16. The individual sections of the cable 12, here as elongate members and/or wire elements, are received in the slots of the respective receivers 8, e.g. are clipped and/or clamped therein. The cross-section of the slot is at least as large as the cross-section of the cable 12 as the elongate member. A slot opening is arranged between the ends of the two slot walls 14, 16, but the width of the slot opening is smaller than the diameter of the cable 12. In an embodiment, at least one of the slot walls 14, 16 or the respective leg of the receiver 8 is elastically deformable, such that the slot walls 14, 16 can splay relative to each other when the section of the cable 12 is disposed therein. Furthermore, the sections of the cable 12 can be received in the corresponding grooves of the receiver 8 in a manner such that they can be released. The cable 12 is here received in its entirety along the fastening strip 2 in the grooves of the receivers 8.

The two groove walls 14, 16 of the receiving part 8 are designed and shaped here only schematically. The first groove wall 14 has a straight profile, while the second groove wall 16 has a curved profile and is longer or higher than the first groove wall 14. The first groove wall 14 surrounds the groove and the cable 12 arranged therein with a flat or straight surface. The second groove wall 16 surrounds the groove and the cable 12 arranged therein with a curved or bent surface, wherein the first groove wall 14 and the second groove wall 16 are oriented at an acute angle relative to each other. If the cable 12, which is cylindrical in cross section, is arranged in the groove between the two groove walls 14, 16, the curved face of the second groove wall 16 bears against the surface of the cable 12 and surrounds the cable over an angular range of up to 90 °. In this case, the flat surface of the first groove wall 14 bears along a line against the cable 12.

Due to the elastic deformability of the film hinge 6, the fastening strip 2 and the cable 12 received therein can be arranged straight (fig. 1) or curved or bent to different extents (fig. 1b and 1 c). The individual carrier elements 4 can be tilted relative to one another by means of the film hinges 6 and can be adapted to surfaces that are curved or arched in different ways. Furthermore, it is proposed that the fastening strip 2 and the received cable 12 are fastened to a surface of a component, not shown here, wherein the fastening strip 2 is adapted to the outer plate profile (Strak) of the component and thus to the geometry or design contour and/or surface contour of the component. In the embodiment, the fastening strip 2 is fastened to a component of the motor vehicle, for example to a body component, a bumper, a diffuser or a cover, in particular a trunk cover, or to a door for opening the motor vehicle, wherein the fastening strip 2 can be adapted to the respective contour and/or geometry of a surface, in particular a surface, of the component. The fastening strip 2 can thus be fastened to differently shaped components of different structural families.

The carrier element 4 is formed or produced from a plastic, for example polypropylene (PP) or ethylene-propylene-diene rubber (EPDM), in particular "PP EPDM T20". The film hinge 6 is injection-molded onto the carrier part 4. Alternatively, all parts of the fastening strip 2, i.e. the carrier piece 4 and the film hinge 6, can be manufactured as a one-piece element. The length of the fastener 2 can then be flexibly adjusted. If, for example, the actual length of the fastening strip 2 is longer than the target length, the fastening strip 2 can be shortened by removing sections of the fastening strip 2. Conversely, if the actual length of the fastening strip 2 is shorter than the target length, for example, the fastening strip 2 may be lengthened by adding further sections of the fastening strip 2. The ends of the two fastening strips 2, at which in each case one carrier part 4 is present, are connected to one another by film hinges 6, which are fastened to the two carrier parts 4.

The carrier element 4 and thus the fastening strip 2 are fastened to the base surface of the component, for example by means of an adhesive pad or a double-sided adhesive tape as adhesive 10. The cable 12 or the line (which may also be designed as an antenna) is then fastened, for example, to a shaped receptacle 8, for example a clip, of the carrier element 4. The individual carrier elements 4 at the ends of the fastening strips 2 can be broken off at the film hinges 6 without being required or damaged.
