Description

The invention relates to a fastener for holding cables or hoses, especially in a vehicle running cables or hoses.

There are known fasteners which serve to fix cables or hoses or strands on a carrier, in particular on a panel or on a frame in a vehicle. For this purpose, such a fastener having a shaft with a plurality of at least partially circumferential grooves or projections, which can be inserted into a hole on the carrier. The at least partially encircling grooves or projections can ensure that the shaft is held therein by a detent after insertion into the hole therein. Such a fastening is also known as a Christmas tree fastener or fir-tree fastener.

Attached to an upper surface of the shank is a cable tie having a receiving portion and a fluted tab, wherein the fluted tab may be received in an opening in the receiving portion such that a closed loop is formed through the tab. The closed loop can be downsized by the tab is pulled further and further through the opening in the receiving section. Opening the loop is prevented, for example, by a detent on the receiving portion engages the corrugation on the tab, as is known for cable ties.

Due to the closed loop, the cables or hoses can be passed individually or in strands. By a corresponding tightening of the tab in the receiving section, the cables or hoses or strands can be clamped in the loop, so that they are held on or by the fastening element. If such a fastener is inserted with the shaft in the hole on the carrier, the cables or hoses or strands are also held on the carrier. As a result, a specific cable or hose path can be determined by a corresponding arrangement of such fastening elements on the carrier. For this purpose, holes are to be inserted into the carrier at appropriate intervals, into which the shaft can be inserted with the circumferential grooves or projections.

Such generic fasteners are for example in US 2006/0239796 A1 . US 7793895 B2 . US 7503528 B2 and US 5803413 A shown.

If a plurality of cable or hose paths are provided on a carrier from mutually independent complexes of cables or hoses or strands, each complex is fastened to the carrier by itself over a certain number of such known fastening elements. As a result, a large number of fastening elements can be fastened to the carrier of the vehicle. This has in addition to a high assembly and material costs the consequence that also a large number of holes are to be introduced into the carrier. Optionally, two or more fasteners are disposed adjacent to each other such that the beam is weakened in that area by the holes.

The object of the invention is therefore to provide a fastener that allows in a simple manner holding or setting of cables or hoses on a support, while minimizing the assembly and material costs, while ensuring a high degree of flexibility.

This object is achieved by a fastening element according to claim 1. The dependent claims indicate preferred developments.

• einen Schaft mit mehreren Vorsprüngen, wobei der Schaft, vorzugsweise durch seine Symmetrieachse, eine Zentralachse definiert und die Vorsprünge derartig von dem Schaft abstehen, dass der in ein vorzugsweise kreisrundes Loch in einem Träger eingesteckte Schaft über die Vorsprünge am Träger gehalten werden kann zum Fixieren des Befestigungselementes am Träger. Somit wird am Befestigungselement ein sog. Tannenbaumverschluss ausgebildet, der zum Halten von Kabeln und/oder Schläuchen insbesondere an einem Träger in einem Fahrzeug, beispielsweise einem Fahrzeugsitz, vorgesehen ist. Als Kabel kommen elektrische Kabel in Frage und als Schläuche können beispielsweise druckmittelführende Schläuche (Pneumatik) aber auch seilführende Schläuche (Seilzugmechanismen) vorgesehen sein.

Accordingly, a fastener for holding cables and / or hoses is provided, comprising at least:

• a shaft having a plurality of projections, wherein the shaft, preferably by its axis of symmetry, defines a central axis and the protrusions protrude from the shaft such that the shaft inserted into a preferably circular hole in a carrier can be held over the protrusions on the carrier to fix the shaft Fastener on the carrier. Thus, a so-called. Christmas tree closure is formed on the fastener, which is provided for holding cables and / or hoses, in particular on a support in a vehicle, such as a vehicle seat. As cable electrical cables in question and as hoses, for example, pressure medium-carrying hoses (pneumatics) but also cable-carrying hoses (cable mechanisms) may be provided.

Thus, a so-called. Cable tie is formed, which can be held by the Christmas tree closure in a hole of a carrier, so that thereby a first complex of cables or hoses can be held on the carrier.

According to the invention, the fastening element furthermore has a hollow body with an inner space for receiving a second complex of at least one cable and / or at least one tube, which can be inserted through the hollow body or plugged in at the end, through the hollow body, preferably through its axis of symmetry , A hollow body axis is defined and the central axis passes through the hollow body and the central axis intersects the hollow body.

Thus, with such a fastener advantageously provides a simple way to hold two different complexes of cables and / or hoses with only one fastener on the carrier. As a result, the installation effort is reduced, in particular for introducing the holes and for inserting the fastening element into the hole of the carrier. At the same time the material costs are reduced because, for example, parallel or intersecting complexes, which are otherwise secure at certain positions by two fasteners, can be secured by only one fastener according to the invention. As a result, fasteners can be saved and holes can be reduced in the carrier, which provide for a partial weakening of the wearer. This also positions can be used for attachment, where otherwise only space for only one fastener.

Preferably, different orientations are provided between the central axis and the hollow body axis, whereby the flexibility of such a fastening element can be increased. According to one embodiment, it is provided that the central axis runs perpendicular to the hollow body axis. Accordingly, the cables and / or hoses received by the hollow body extend perpendicularly to the insertion direction of the shaft into the carrier. Thereby, the cables can be guided by the fastening element parallel to a surface of the carrier. Preferably, it can be additionally provided that the central axis intersects the hollow body axis at a point, so that a symmetrical construction of the fastening element can be achieved.

According to an alternative embodiment, it is provided that the central axis runs parallel to the hollow body axis, wherein preferably both lie on one another. Depending on the field of application, end pieces of cables or hoses, for example, which are to be held parallel to the insertion direction of the shaft and perpendicular to the surface of the carrier by the fastening element, can be received with such a fastening element.

Also, the loop axis can be set in a variable manner by a corresponding positioning of the receiving portion or the opening. For example, it may be provided that the loop axis runs parallel or at an angle, preferably perpendicular to the hollow body axis. Thus, the alignment of the two complexes of cables and / or hoses, which are received by a fastener at a certain position can be determined. Accordingly, depending on the cable or hose path, the corresponding fastening means can be selected and introduced into the carrier at the corresponding positions in order to adhere to the predetermined cable or hose path.

Preferably, it is provided that the loop axis does not run through the hollow body and / or the hollow body axis through the loop, so that the two complexes do not interfere with each other.

Preferably, it is further provided that the receiving portion between the hollow body and the shaft is arranged. As a result, good accessibility to the hollow body can be achieved.

It is provided that the hollow body is a hollow cylinder open on both sides or on one side, in the cylindrical interior of which the cables and / or hoses can be accommodated. Depending on the position of the hollow body axis relative to the central axis can be ensured by such a shape simple Einsteckbarkeit and optimal hold of the second complex.

Preferably, it is further provided that the tab is held by friction and / or by a detent in the opening. As a result, a simple and reliable hold of the first complex can be ensured.

Furthermore, it can be provided that a plate-shaped element is arranged on an upper side of the shaft. This can serve as a stop for the insertion of the shaft into the hole on the carrier and at the same time prevent by elastic resilience vibrate the fastener in the inserted state.

The invention will be explained in more detail below with reference to figures. Show it:

• 1 an inventive fastener in a first embodiment;
• 2a . 2 B the fastener according to 1 in different perspective views;
• 3 an inventive fastener in a second embodiment;
• 4a . 4b the fastener according to 3 in different perspective views.

According to 1 is a fastener 1a shown in a first embodiment. This has a shaft 2 on, whose axis of symmetry is a central axis C Are defined. On the outside of the shaft 2 are according to 2a and 2 B several partially circumferential and offset from each other protruding projections 3 arranged. These serve to fasten the fastener 1a in a circular hole of a carrier, not shown, for example, a fairing or a frame in a vehicle to record and fix it. This is the shaft 2 with a bottom 2a in the direction of the central axis C plugged into the circular hole of the wearer. The trained projections 3 engage behind the circular hole of the carrier in this state such that a removal of the fastener 1a is prevented from the hole on the carrier and the fastener 1a is held thereby. Such attachment is also known as Christmas tree fastener or fir-tree fastener.

On a top 2 B of the shaft 2 is a plate-shaped element 4 arranged, in the inserted state of the fastener 1a covers the circular hole in the carrier and thus acts as a stop and the carrier is optionally applied under a slight tension to vibrate the fastener 1a to avoid during operation.

According to the first embodiment of the fastening element 1a is at the top 2 B of the shaft 2 above the dish-shaped element 4 a receiving section 5 with an opening 6 provided that the receiving section 5 completely penetrates. The recording section 5 serves a tab 7 to pick up and hold, with the recorded and held tab 7 a closed loop 8th (S. 2a dashed) trains. The recording section 5 and the tab 7 thus form a kind of cable tie, which can be used in a known manner to one or more cables or hoses within the closed loop 8th to keep.

Around the closed loop 8th to fix, is the tab 7 For example, superficial grooved or toothed. Will this fluted or toothed tab 7 through the opening 6 in the recording section 5 plugged, so is the closed loop 8th educated. At the same time engages a corresponding locking element (not shown) in the opening 6 in the corrugation or perforation on the surface of the tab 7 such a way that the tab 7 no longer out of the opening 6 can be removed. This allows the closed loop 8th be secured and recorded therein cables or hoses are held.

The cables or hoses are doing along a loop axis S held by the closed loop 8th is defined. The loop axis S runs perpendicular to the central axis C but does not cut them. The orientation of the loop axis S can by the arrangement of the opening 6 or their recording axis A be set, the recording axis A also perpendicular to the central axis C runs and this cuts. This is the recording section 5 with the opening 6 above the shaft 2 on the central axis C arranged.

According to the 2a and 2 B is above the receiving section 5 furthermore a hollow body 9 arranged, which is formed according to this embodiment by a hollow cylinder which is open on both sides. Through an interior 9a of the hollow body 9 One or more cables or hoses can be inserted. Therefore, with such a fastener 1a two different complexes K1 . K2 held by cables or hoses, being a first complex K1 from the closed loop 8th that goes through the tab 7 is formed, and a second complex K2 through the hollow body 9 can be held.

From the hollow body 9 protrude elastic attachment tabs 9b in the interior 9a on the inserted cables or hoses of the second complex K2 can rest from outside to those in the interior 9a to center in about and protect against vibration.

A hollow body axis H passing through the symmetry axis of the hollow body 9 is formed, runs parallel to the receiving axis in this embodiment A and perpendicular to the central axis C of the shaft 2 , It is also the hollow body 9 above the shaft 2 on the central axis C arranged. The loop axis S is still perpendicular to the hollow body axis H aligned so that of the cable tie or the closed loop 8th held cables or hoses of the first complex K1 perpendicular to in the hollow body 9 held cables or hoses of the second complex K2 be guided. In principle, however, it is also possible that the hollow body 9 in this first embodiment of the fastener 1a to the central axis C is twisted as a rotation axis, so that the hollow body axis H and the loop axis S at an angle of not equal to 90 ° to each other. A parallel alignment with each other is conceivable. Accordingly, can be adjusted selectively, as of the hollow body 9 held second complex K2 relative to that of the cable tie or of the closed loop 8th held first complex K1 should run.

A fastener 1a can therefore have two different complexes K1 . K2 hold of cables or hoses, these being in the inserted state of the fastener 1a can be fixed point by point to the respective carrier. Because two different complexes K1 . K2 with only one fastener 1a can be held pointwise, for example, two intersecting or two at least partially parallel complexes K1 . K2 be fixed at respective positions via only a circular hole on the carrier. As a result, material can be saved and the carrier is less weakened against attachment via one fastener per complex K1 . K2 ,

In 3 is a second embodiment of a fastener 1b shown. This does not differ in the basic function of the fastener 1a the first embodiment. Accordingly, can also with this fastener 1b two different complexes K1 . K2 held by cables or hoses and fixed to a support via a circular hole. For this purpose, the fastener 1b in this embodiment also a shaft 2 with projections 3 on that with a bottom 2a can be inserted into the circular hole in the carrier to the fastener 1b safe to hold on the carrier (Christmas-tree fastener or fir-tree fastener).

Furthermore, in this embodiment is a hollow body 9 provided, an interior 9a in which, according to this embodiment, an end portion of one or more cables or tubes of the second complex K2 can be included. The hollow body 9 is in contrast to the first embodiment of the fastener 1a not opened on both sides, so no cables or hoses through the hollow body 9 can be inserted through. Accordingly, the hollow body serves 9 merely attaching or receiving an end piece of the cables or hoses of the second complex K2 ,

The hollow body 9 is according to this embodiment, such on the top 2 B of the shaft 2 arranged that the hollow body axis H parallel to the central axis C runs or these lie on each other. This will cause the hollow body 9 to one side from the top 2 B of the shaft or of the dish-shaped element 4 at least partially covered or closed. In the inserted state of the fastener 1b in the hole in the carrier, the cables or hoses with their end portion so from above into the hollow body 9 be plugged in.

To hold the first complex K1 is also a fluted or toothed tab in this embodiment 7 and a receiving section 5 provided, which form a cable tie, with a closed loop 8th can be formed when the tab 7 in the opening 6 of the receiving section 5 locks. As a result, in this embodiment, a loop axis S formed, which are both perpendicular to the central axis C as well as the hollow body axis H lies. The recording axis A of the receiving section 5 runs, in particular in 4a shown, parallel to the central axis C and to the hollow body axis H , In principle, however, a different orientation can be selected to the position of the loop axis S to the hollow body axis H adjust and thus the relative positions of the individual complexes K1 . K2 to each other.

This can also with this fastener 1b a specific cable or tube path for the two complexes K1 . K2 be achieved. This is in this embodiment of the fastener 1b given a slightly modified to the first embodiment possibility, but with the same general functionality is achieved, namely two different complexes K1 . K2 of cables or hoses in a particular relative orientation to each other and over the shaft 2 to fix on a carrier, so that at the respective position only one hole in the carrier is necessary.

The complexes K1 . K2 This can consist of individual cables or hoses or cable harnesses or hose strings. Under certain circumstances, a combination is possible. It is also possible that the same cables or hoses via a fastener 1a . 1b be held twice, for example, if the respective cables or hoses are laid in a loop and are guided along the carrier twice at the same position. The same cables or hoses then become the first complex K1 from the loop 8th and once as a second complex K2 from the hollow body 9 held. Also, other elongated objects can by the described fasteners 1a . 1b held and fixed to the carrier.
