  Hereinafter, the best mode for carrying out the present invention will be described in detail with reference to the accompanying drawings.

  FIG. 1A is an explanatory diagram of an example in which the wire harness mounting structure to which the present invention is applied is adopted at a plurality of locations, and FIG. 1B is the same as the wire harness mounting structure to which the first present invention is applied. It is sectional drawing when cut | disconnecting by the AA line in a figure (a).

  The wire harness attachment structure 1A of FIG. 1B is a structure in which the wire harness WH is attached to the harness attachment surface S of the vehicle with the surface fastener 2, and as the vehicle harness attachment surface S to which this structure is applied, For example, the back surface of vehicle interior parts such as a vehicle ceiling trim material, a vehicle door trim material, and the like can be cited, but the invention is not limited to this.

  The wire harness WH is used, for example, for information communication between a lighting device such as a room lamp mounted on a vehicle and a power supply cable for supplying power to various electronic devices, and the various electronic devices and an in-vehicle computer. A predetermined number of various wiring cables C mounted on the vehicle, such as communication cables, are bundled together.

  In the wire harness mounting structure 1A of FIG. 1B, the hook and loop fastener 2 includes a first hook and loop fastener base material 3 attached to the harness mounting face S and a second hook and loop fastener base material 4 attached to the wire harness WH. And.

  A first engagement element 5 is provided on the surface of the first surface fastener base 3, and a first engagement element 5 is engageable on the surface of the second surface fastener base 4. Two engaging elements 6 are provided, and an adhesive material V is applied to the back surface of the second surface fastener base 4. Instead of the adhesive material V, an adhesive material may be applied.

  The first engagement element 5 is formed of a loop material or a hook material that is well known as a hooking member for the hook-and-loop fastener. Here, for example, as shown in FIG. 1B, when a loop material is employed as the first engagement element 5, a hook material is employed as the second engagement element 6. On the contrary, when a hook material is employed as the first engagement element 5, a loop material is employed as the second engagement element 6.

  And in the wire harness attachment structure 1A of FIG.1 (b), said 2nd surface fastener base material 4 demonstrated previously said 2nd so that the back surface may oppose up and down via the adhesive material V (or adhesive material). By folding the surface fastener base material 4 as shown in FIG. 1B, the back surfaces of the second surface fastener base material 4 are brought into close contact with each other via the adhesive material V (or adhesive), and the folding of the surface fastener base material 4 is also performed. When the outer surface of the wire harness WH is wound around the back surface of the second hook-and-loop fastener base 4 as shown in FIG. 1B, the second wire harness WH is connected to the wire harness WH via the adhesive V (or adhesive). The surface fastener base material 4 is fixed. Thereafter, the attachment of the wire harness WH to the harness attachment surface S is completed by engaging the first engagement element 5 and the second engagement element 6.

  FIG. 2 is a cross-sectional view of the wire harness mounting structure to which the second aspect of the present invention is applied, taken along the line AA in FIG.

  The wire harness attachment structure 1B of FIG. 2 is also a structure in which the wire harness WH is attached to the harness attachment surface S of the vehicle with the surface fastener 2 in the same manner as the wire harness attachment structure 1A of FIG. Examples of the harness mounting surface S and the wire harness WH of the vehicle to which this structure is applied are as described above, and detailed description thereof is omitted.

  Further, also in the wire harness mounting structure 1B of FIG. 2, the surface fastener 2 is similar to the wire harness mounting structure 1A of FIG. A second hook-and-loop fastener base 4 attached to the wire harness WH, and a first hook-and-loop fastener base 3 is provided with a first engagement element 5 on the surface of the first hook-and-loop fastener base 3. On the surface of the material 4, a second engagement element 6 that can be engaged with the first engagement element 5 is provided.

  In the wire harness mounting structure 1A of FIG. 1B, the configuration in which the adhesive material V (or adhesive) is applied to the back surface of the second surface fastener base 4 is adopted. In the structure 1B, a third engagement element 7 and a fourth engagement element 8 that can be engaged with the third engagement element 7 are provided on the back surface of the second surface fastener base 4.

  The third engagement element 7 is made of a loop material or a hook material known as a hooking member for the hook-and-loop fastener. Here, for example, as shown in FIG. 2, when a loop material is employed as the third engagement element 7, a hook material is employed as the fourth engagement element 8. On the contrary, when a hook material is employed as the third engagement element 7, a loop material is employed as the fourth engagement element 8.

  In the wire harness attachment structure 1B of FIG. 2, the second engaging element 7 and the fourth engaging element 8 in the second hook-and-loop fastener base 4 described above are vertically opposed to each other. The hook-and-loop fastener base material 4 is folded, the third engaging element 7 and the fourth engaging element 8 facing each other are engaged, and at the time of the folding, the back surface of the second hook-and-loop fastener base material 4 is engaged. The 2nd surface fastener base material 4 is attached to the wire harness 3 by winding in the outer peripheral surface of the wire harness WH. Thereafter, the attachment of the wire harness WH to the harness attachment surface S is completed by engaging the first engagement element 5 and the second engagement element 6.

  The wire harness mounting structures 1A and 1B shown in FIGS. 1B and 2 described above are adopted at a plurality of locations in the length direction with respect to one wire harness WH as shown in FIG. 1A, for example. At the same time, it can be set so that the color of the hook-and-loop fastener 2 is different at each location.

  When the setting of the color of the surface fastener 2 is different at each location as described above, the color of the surface fastener 2 at each location is read by, for example, a color identification sensor, and in what order the read color data is actually used. The wire harness WH with respect to the harness mounting surface S is obtained by acquiring whether the colors are arranged or not, and by comparing the obtained actual color arrangement and the set value (predetermined color arrangement). It can be determined whether or not the attachment position of the wire harness WH with respect to the harness attachment surface S is correct, such as whether or not the attachment position of the wire harness is shifted in the harness length direction. The color reading by the identification sensor as described above and the comparison with the set value may be performed by a computer.

  In the wire harness mounting structures 1A and 1B described above with reference to FIGS. 1 and 2, as a means for attaching the second surface fastener base material 4 to the wire harness WH, it is applied to the back surface of the second surface fastener base material 4. The third engagement element 6 and the fourth engagement element 7 provided on the back surface of the second hook-and-loop fastener base 4 using the adhesive material V (or adhesive) that has been used. Both use engagement, both abolishing fixed plates and vinyl tape that have been used as such attachment means, and abolishing vinyl tape wrapping work (see << Working Procedure 1 >> above) Therefore, it is possible to reduce the number of attachment parts and the number of attachment work steps of the wire harness WH.

  In particular, in the wire harness mounting structure 1B of FIG. 2, as described above, as a means for attaching the second surface fastener base material 4 to the wire harness WH, a method that does not use the adhesive material V (or adhesive material), that is, the third The second hook-and-loop fastener base 4 is folded so that the engaging element 6 and the fourth engaging element 7 face each other in the vertical direction, and the third engaging element 6 and the fourth engaging element 7 are In addition to being engaged, a method was adopted in which the outer peripheral surface of the wire harness WH was wound on the back surface of the second surface fastener base 4 during the folding. For this reason, the wire harness WH can slide in the length direction and the circumferential direction when viewed from the second surface fastener base 4, and the twisting and slack of the wire harness 3 can be absorbed by the operation of such a slide. For example, it is possible to effectively prevent problems caused by the wire harness WH being attached to the harness attachment surface S while being twisted (specifically, the peeling failure of the surface fastener 2 due to the reaction force of the twist).

  The present invention is not limited to the embodiments described above, and many modifications can be made by those having ordinary knowledge in the art within the technical idea of the present invention.

  For example, in the wire harness attachment structure 1A of FIG. 1B, since the adhesive material V (or adhesive) is applied to the entire back surface of the second surface fastener base material 4, the second surface The form when the 2nd surface fastener base material 4 is folded so that the back surface of the fastener base material 4 may oppose up and down via the adhesive material V (or adhesive material) is folded like FIG.1 (b). In addition, the adhesive material V (or adhesive material) is vertically opposed between the second surface fastener base materials 4, and any one of the adhesive materials V (or adhesive materials) facing up and down as such. By making one form omitted, the back surfaces of the second surface fastener base material 4 may be brought into close contact with each other through the other adhesive material V (or adhesive) which is not omitted.

  In addition, in the wire harness mounting structure 1A of FIG. 1B, the second surface fastener base material so that the back surface of the second surface fastener base material 4 is vertically opposed via the adhesive material V (or adhesive material). 4 is folded, but as another embodiment, the second surface is such that the back surface of the second surface fastener base 4 faces left and right or diagonally via the adhesive material V (or adhesive). You may comprise so that the fastener base material 4 may be folded.

  Further, in the wire harness mounting structure 1A of FIG. 1B, the second hook-and-loop fastener base material 4 is folded so that the third engagement element 6 and the fourth engagement element 7 face each other vertically. However, as another embodiment, the second hook-and-loop fastener base 4 is folded so that the third engagement element 6 and the fourth engagement element 7 face each other left and right or obliquely. May be.
