Definitions
- the invention relates to a holder for tubular components with a receptacle body that has a holding area and a receptacle for at least one component, and with a fastening element that has a longitudinal axis and is arranged in an opening in the receptacle body.
- Holders of the specified type are used to fasten a tubular component to a carrier.
- a common application of such holders is found in motor vehicles, where they are used for fastening brake or fuel lines, as well as cables.
- the receiving body and the fastening element are two parts which are produced separately from one another and are joined together when the holder is assembled.
- the fastening element consists of a cylindrical sleeve with a head designed as a flange, which is inserted into a circular hole in the holder.
- the holder can be fastened with its fastening element to a bolt, for example welded to the body of a motor vehicle, this penetrating into the sleeve bore of the fastening element.
- EP 0 597 718 A1 discloses a holder for pipelines which is to be fastened by means of a fastening element in the manner of a nut to a threaded pin connected to a plate.
- the holder in this case has a coupling member which connects the holder to the fastening element and which can be moved perpendicular to the longitudinal axis of the pipeline held in a recess of the holder relative to the latter.
- the coupling member also has a recess for receiving the shaft of the fastening element.
- the recess has an excess length in the longitudinal direction of the pipeline held.
- the invention has for its object to provide a stable holder for tubular components, which is simple to manufacture and easy to assemble and which allows compensation for dimensional deviations in terms of the position of the tubular components and the attachment point in any direction.
- a space extending in all directions radial to the longitudinal axis of the fastening element is provided to compensate for dimensional deviations during installation, and the fastening element is connected to the receiving body by connecting elements connected and held in a defined position, in particular a central position, in the opening of the receiving body, the connecting elements being separable or deformable in such a way that they do not hinder the compensatory movement of the fastening element within the opening.
- the holder according to the invention makes it possible to compensate for dimensional tolerances of considerable size when fastening pipelines and cables, for example in motor vehicles.
- the holder according to the invention also has the advantage that it can be produced inexpensively in one piece from plastic. Additional effort for the completion of several parts is eliminated, and the mounting of the holder is very simple due to the one-piece design.
- the fastening element of the holder according to the invention is preferably designed as a sleeve with a sleeve bore for receiving a bolt and can be fastened by movement in the direction of its longitudinal axis, for example a correspondingly directed impact on the bolt.
- the fastening element is arranged in the receiving body in such a way that it can be moved axially into the fastening position relative to the receiving body during assembly. This axial movement can cause the connecting elements to break, so that the receptacle body and the fastening element are separated before the final fastening position of the holder is reached and the receptacle body can carry out the compensating movement necessary to compensate for dimensional deviations.
- the connecting elements can consist of thin-walled webs which bridge an axial and / or radial intermediate space between the fastening element and the receiving body.
- the thin-walled webs between the edge of the opening in the holding area of the receiving body and a flange of the fastening element which interacts with the holding area are arranged at an angle to the longitudinal axis thereof. In this way, a sufficiently strong fixation of the fastening element on the receiving body is achieved and the webs are broken by the axial force acting on the fastening element during the assembly process.
- the shape for injection molding the holder can also be simple in this embodiment of the webs.
- the webs bridge a radial space between a flange of the fastening element and walls of the holder that are adjacent thereto, the webs being able to be broken through by an axial movement of the fastening element relative to the holder.
- the connecting elements can be designed as elastically deformable rockers, which follow the compensating movements of the fastening element with respect to the receiving body and are not severed during assembly of the holder.
- the rockers can additionally serve to secure the fastening element against rotation and prevent the fastening element from loosening automatically from a bolt provided with a screw thread.
- the rockers are preferably separated from the fastening element here only if the fastening element is forcibly rotated in the release direction with the aid of a tool.
- a further embodiment of the invention provides a ring membrane as a connecting element between the receiving body and the fastening element, which is produced together with the receiving body and the fastening element in a common shape.
- the ring membrane is preferably made of a rubber-like material and is bead-like thickened at its edges and anchored in each case in an annular groove of the receiving body or the fastening element.
- the very thin-walled membrane can be broken, elastically deformed or torn by the compensating movements of the fastening element relative to the receiving body, without thereby impairing the necessary compensation.

- FIG. 2 shows a view of the holder according to FIG. 1 from above
- FIG. 3 shows a cross section through a second embodiment of a holder with frangible connecting elements
- FIG. 4 shows a view of the holder according to FIG. 3 from above
- FIG. 5 shows a side view of a holder with elastic rockers
- FIG. 6 shows a cross section A-A of the holder according to FIG. 5,
- Figure 7 shows an axial section of a holder with a connecting element formed by a membrane
- Figure 8 is a view of the holder of Figure 1 in the mounting position.
- the holder 1 consists of a receiving body 2 and a fastening element 3, which serves to fasten the receiving body 2 to a support part provided with a threaded bolt.
- the receiving body 2 has a central holding area 4 and 4 receptacles 5 for tubular components on both sides of the holding area.
- Each receptacle 5 is formed by a partially cylindrical shell 6, which is open to the contact side of the receptacle body 2.
- a blocking element 7 which extends from a wall 8 arranged laterally next to the shell at an angle to the latter in the direction of the opening.
- the locking elements 7 are resilient and can deflect resiliently towards the wall 8 for inserting a tubular component into the shell 6. As soon as the component is in the shell 6, the locking element 7 returns to its starting position, in order to thereby hold the component in the shell 6.
- the holding area 4 of the receiving body 2 has a flat contact surface 9 parallel to the axes of the shell 6 and a central cylindrical bore 10 perpendicular to the contact surface 9.
- Guide elements 12, 13 are provided on both sides of the holding surface 11, which serve to guide and support the holder 1 in an assembly device.
- the fastening element 3 has a cylindrical sleeve 14, an annular flange 15 projecting radially outward from the sleeve 14 and a head 16.
- the sleeve 14 is arranged with a substantial part of its length in the bore 10 and aligned coaxially with this.
- the outer diameter of the sleeve 14 is smaller than the inner diameter of the bore 10 by an amount required to compensate for dimensional tolerances.
- the annular flange 15 is located outside the bore 10 at a distance from the holding surface 11.
- the annular flange 15 is also at a distance from the guide elements 12 , 13, which is at least as large as the space between the sleeve 14 and the wall of the bore 10.
- the fastening element 3 is connected to the receiving body 2 by a plurality of thin-walled webs 17, which bridge the gap between the holding surface 11 and the annular flange 15.
- the webs 17 are connected at one end to the edge of the bore 10 adjoining the holding surface 11 and are convergingly inclined at an angle of approximately 30 ° to the bore axis towards the flange 15.
- the connection points of the webs 17 are at a distance from the outer surface of the sleeve 14.
- the ring flange 15 has a fillet groove 18, which serves to accommodate fragments of the webs 17.
- the sleeve 14 has a sleeve bore 19 which extends from the sleeve end adjacent to the contact surface 9 into the head 16.
- the end of the sleeve bore 19 adjacent to the contact surface 9 is provided with a chamfer 20 of 45 ° to facilitate the insertion of a retaining bolt.
- the sleeve bore 19 is provided with a vent hole 21.
- the head 16 also has a radially extending slot which is used to attach a screwdriver.
- the holder 1 can be produced with comparatively simple primary molding tools in an injection molding process from plastic.
- the formation of the webs 17, which connect the fastening element 3 to the receiving body 2, can take place here by means of cutouts on the tool parts, which on the one hand surround the sleeve 14 and on the other hand the ring flange 15.
- the fastening element 3 is pressed into the bore 10 of the receiving body 2 by an axial force until the ring flange 15 rests on the holding surface 11.
- the webs 17 break, so that the fastening element 3 is freely movable relative to the receiving body 2 in the radial direction, with respect to its longitudinal axis, to an extent that the gap between the sleeve 14 and the wall of the bore 10 permits. In this way, deviations from the nominal dimension between the position of the fastening element 3 and the position of the tubular components held by the receiving body 2 can be compensated for during the mounting of the holder 1.
- the holder 101 shown in FIGS. 3 and 4 differs from the holder according to FIGS. 1 and 2 only with regard to the arrangement of the webs 117, which connect the receiving body 102 to the fastening element 103.
- the webs 117 here extend on two opposite sides from the peripheral edge of the ring flange 115 to a respective guide element 112 or 113, the connection points on the guide elements 112, 113 being at a greater distance from the holding surface 111 than the connection points on the ring flange 115.
- the fastening element 103 is pressed with its ring flange 115 onto the holding surface 111, the webs 117 break off, so that the fastening element 103 is separated from the receiving body 102 and can perform compensating movements relative to the latter.
- the fastening element 203 is connected to the receiving body 202 by elastically deformable rockers 222.
- the rockers 222 are located in recesses 223 in the holding surface 211 of the receiving body 202.
- the rockers 222 have a straight section 224 connected to the receiving body 202, which extends parallel to the longitudinal axis of the shells 206, and a curved section 225, which connects with the Fastening element 203 is connected.
- the rockers 222 are resilient and have such a large free movement space within the recesses 223 that the sleeve 214 of the fastening element 203 is transverse to the longitudinal axes of the Shells 206 can move in both directions up to the wall of the bore 210 relative to the receiving body 202.
- the rockers 222 are connected to the fastening element 203 such that they can break off when the fastening element 203 is rotated.
- FIG. 7 shows an exemplary embodiment of a holder 301, in which the fastening element 303 is connected to the receiving body 302 by an annular membrane 326.
- the ring membrane 326 is also formed in the same tool, the ring membrane 326 either being made of the same material as the other two parts of the holder 301 or of a different, in particular softer and more stretchable plastic material, as in FIG Figure 7 shown.
- the ring membrane 326 which consists of a softer material component, has thickened beads 327, 328 at its edges, with which it is anchored in ring-groove-like depressions in the sleeve 314 of the fastening element 303 and in the holding surface 311 of the receiving body 302.
- the ring membrane 326 extends essentially in the plane of the holding surface 311. When the holder 301 is assembled, it is stretched or torn depending on the compensating movement of the fastening element 303.
- FIG. 8 shows the holder 1 in a typical mounting position on the floor plate 27 of a vehicle.
- a bolt 28, which is provided with an external thread, is welded to the base plate and is used to fasten the holder 1.
- the holder 1 is first connected to the pipes 29, 30 by snapping them into the shells 6 of the receptacles 5. Subsequently, the holder 1 with the fastening element 3 is brought up to the bolt 28, the chamfer 20 making alignment easier.
- the fastening element 3 is driven onto the bolt 28, for example by a blow to a head 16, as a result of which it reaches the position shown in FIG. 8, in which the receiving body 2 with its contact surface 9 is pressed against the base plate 27. In this process, the webs 17 are broken, so that the receiving body 2 through the pipes 29, 30 transversely to the bolt axis around Dimension x can be moved from its original central position into a position in which the pipes 29, 30 are not braced.
