This vehicle is an automatic vehicle, and an accelerator pedal 51, a brake pedal 52, and the like are arranged in the dash floor portion on the driver's side, and a floor carpet 53 is laid over substantially the entire floor panel. The floor carpet 53 is formed as a three-dimensional one piece according to the shape of the vehicle body floor as shown in FIG. 4, and after being laid on the vehicle body floor, the side terminal portion 53a of the floor carpet 53 attaches the mounting retainer 54. It is locked and fixed to the side sill side of the vehicle body floor side.

In recent years, a wire or an electric harness has been arranged along a shoulder surface of a side sill portion which constitutes a vehicle body, and a harness protector covers the wire surface. Therefore, a structure in which the side protector of the floor carpet is processed by using this harness protector has been known.

FIG. 5 and FIG. 6 show an example of a structure in which a side end portion of a floor carpet is fixed by using such a protector for harness. A strip-shaped attachment retainer 54 is attached to the side terminal portion 53a of the floor carpet 53 along the side terminal portion 53a. The mounting retainer 54 is a resin-made long object, and a square engagement hole 55 is formed at a plurality of positions along the longitudinal direction. The engagement hole 50 is set to be slightly larger in consideration of the operability of engagement and the variation in size.

On the other hand, on the floor side of the vehicle body, the side sill portions 57, which form the lower portion of the vehicle body, are welded to the left and right ends of the floor panel 56 and extend in the front-rear direction. The side sill portion 57 is composed of a sill inner panel 57A and a sill outer panel 57B. The upper flange portions 57a and the lower flange portions 57b of both panels 57A and 57B are abutted and integrated with each other. On the shoulder surface 57c, upper flange portions 57a abutted against each other extend in the front-rear direction to form a standing wall 58. An electric harness 59 is arranged on the shoulder surface 57c of the sill inner panel 57A in the front-rear direction along the standing wall 58, and the electric harness 59 is covered with a protector 60 for the harness.

The protector 60 integrally includes a horizontal portion 60a, an inner vertical portion 60b and an outer vertical portion 60c that are bent downward from the left and right ends of the horizontal portion 60a, respectively. The opening has a substantially U-shaped cross section. Further, the tip portion 60d of the inner vertical portion 60b is slightly bent inward. Although not shown, a clip is formed on the lower surface of the tip portion 60d, and when this clip is press-fitted into an engaging hole (not shown) formed on the shoulder surface 57c of the sill inner panel 57A, the clip engages with the clip. The structure is such that the protector 60 can be mounted on the shoulder surface 57c by engagement with the dowel hole (see Japanese Utility Model Laid-Open No. 2-26949). Further, on the upper surface of the horizontal portion 60a, a locking projection 61 with a claw portion 61a protruding outwardly is integrally formed at the tip end corresponding to the engagement hole 55.

When fixing the side terminal portion 53 a to the protector 60 described above, first, the floor carpet 53 is laid on the floor panel 56, and then the engaging holes 55 of the mounting retainer 54 are respectively associated with the engaging holes 55. The stop projection 61 is inserted, and the peripheral edge of the engagement hole 55 is hooked on the claw portion 61a of the locking projection 61 to engage with the same. Further, after this, the kicking plate 62 is attached to the shoulder surface 57c of the sill outer panel 57B, and the side terminal portion 53a and the protector 60 are covered with the kicking plate 62. The kicking plate 62 includes a lower horizontal wall portion 62a fixed to the shoulder surface 75c, a vertical wall 62b bent upward from one end of the lower horizontal wall portion 62a, and an upper end of the vertical wall portion 62b. The upper horizontal wall portion 62c that is bent and the contact wall portion 62d that is bent at the tip of the upper horizontal wall portion 62c are integrally formed.

[0008]

[Problems to be solved by the device]

 In the above-described conventional floor carpet terminal fixing structure, when the locking projection 61 on the protector 60 side is engaged with the engagement hole 55 of the mounting retainer 54 and then the kicking plate 62 is mounted, the contact wall portion Since 62d presses the floor carpet 53 from the upper side, the engagement between the engagement hole 55 and the claw portion 61a is not easily disengaged. However, there were problems as shown in the following (a) to (c) during the assembly process before the kicking plate 62 was attached.

(A) Since the mounting retainer 54 can move a little in the outward direction, which is the direction in which the claw portion 61a of the locking projection 61 projects, with respect to the protector 60, the mounting retainer 54 can be moved to the floor during the assembly. When the carpet 53 is moved in the outward direction together with the carpet 53, the engaged locking projection 61 may come out of the engaging hole 55 and come off before the kicking plate 62 is attached. (B) The attachment retainer 54 has a long strip-like plate shape formed by extrusion molding, and a plurality of engagement holes 55 are formed at predetermined intervals in advance. Therefore, the accuracy of the side sill portion 57 and the installation of the protector 53 are set. Depending on the accuracy or the relative positional accuracy with respect to the plurality of locking projections 61, the corresponding locking projections 61 may not be able to be engaged. (C) It should be noted that the longer the mounting retainer 54 is, the more difficult it is to maintain its flatness due to the warpage after it has been molded, so that the engaging operation at the above-mentioned multiple points cannot be performed smoothly and is easily disengaged. , Work efficiency is poor.

An object of the present invention is to solve the above problems, and to provide a terminal fixing structure for a floor carpet of a vehicle, which can alleviate the dimensional accuracy of each member and improve the workability of installation. It is in.

[0011]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention relates to a vehicle floor carpet terminal fixing structure in which a side end portion of a carpet is locked to a harness protector installed on a side sill portion of a vehicle body floor side through a mounting retainer. The mounting retainer is formed as a substantially inverted L-shaped small piece, while the protector has a substantially U-shaped cross section of the lower opening and is provided in a vertical portion on one side of the U-shaped retainer so that the L-shaped mounting retainer is provided. It has an upper opening locking groove into which the vertical part can be inserted, and a plurality of the mounting retainers are scattered on the side end of the carpet and fixed at the horizontal part. The gist is to insert the vertical portion of the mounting retainer into the locking groove to lock it.

[0012]

[Action]

 According to the above configuration, the mounting retainer is locked by inserting the vertical portion thereof into the locking groove on the protector side. In this case, since the locking groove is provided in the protector and is open upward, it is possible to easily insert the corresponding vertical portion of the mounting retainer. In the locked state, the mounting retainer is also restricted from moving horizontally and upwardly, so that it is prevented from moving together with the floor carpet. Further, the mounting retainer of the conventional structure is formed in the shape of a strip plate having a plurality of engaging holes, whereas it is formed of small pieces and is provided scattered at the side terminal portions. The insertion work into the stop groove will be carried out for each small piece one after another, and the dimensional accuracy of each member can be sufficiently absorbed by the elasticity of the carpet. Further, since one side vertical portion of the mounting retainer itself is inserted into the engaging groove in the conventional engaging structure of the engaging hole and the engaging protrusion, the engaging or engaging workability is good.

【Example】

 Embodiments of the present invention will be described below with reference to the drawings. 1 and 2 show an embodiment of the present invention. 1 and 2, parts corresponding to those in FIGS. 3 to 6 are designated by the same reference numerals and will be described.

FIGS. 1 and 2 utilize the harness protector 4 covering the electrical equipment harness 59 arranged along the shoulder surface 57 c of the side sill portion 57 to utilize the side terminal portion 53 a of the floor carpet 53. It shows the structure of the main part that is fixed. A plurality of small-sized attachment retainers 2 are scattered and attached to the side terminal portions 53a of the floor carpet 53. The mounting retainer 2 is a substantially L-shaped resin molded body, and integrally has a horizontal portion 2a and a vertical portion 2b. The horizontal portion 2a is provided with a square engagement hole 3 penetrating vertically. Each mounting retainer 2 is fixed by stapling the horizontal portion 2a directly below the side terminal portion 53a, and the vertical portion 2b faces downward.

The vehicle body floor side is the same as the conventional one, and side sill portions 57 that constitute the vehicle body lower side portion are spot-welded to both left and right ends of the floor panel 56 and extend in the front-rear direction. The side sill portion 57 is composed of a sill inner panel 57A and a sill outer panel 57B. The upper flange portions 57a and the lower flange portions 57b of both panels 57A and 57B are brought into contact with each other, and spot welding is performed between them. The side wall portion 57 is formed in a substantially cylindrical shape, and on the shoulder surface 57c of the side sill portion 57, a standing wall 58 extending in the front-rear direction is formed by the upper flange portions 57a abutted against each other. On the shoulder surface 57c of the sill inner panel 57A, an electric harness 59 is arranged in a front and rear direction along the standing wall 58, and the electric harness 59 is covered with the harness protector 4.

The protector 4 is a resin molded body that is injection molded, and includes a horizontal portion 4a, an inner vertical portion 4b and an outer vertical portion 4c that are bent downward from both left and right ends of the horizontal portion 4a. Is integrally formed and has a substantially U-shaped cross section with an open lower surface. The tip portion 4d of the outer vertical portion 4c is slightly bent inward. Further, the inner vertical portion 4b is provided with a locking groove 3 which is opened upward and is continuously provided in the front-rear direction, and the lower end of the inner vertical portion 4b is extended downward to form a scart portion 4e. Has been formed. The width of the locking groove 3 is slightly larger than the thickness of the vertical portion 2b of the mounting retainer 2 in the opening portion, and gradually becomes smaller than the thickness of the vertical portion 2b as it goes to the groove bottom. It is formed in a taper shape and has a structure capable of being press-fitted and locked by pushing the vertical portion 2b into the locking groove 3. In addition, the clip 5 is formed on the inner surface of the skirt portion 4e (the surface facing the sill inner panel 57A) so as to face an engagement hole (not shown) formed in the sill inner panel 57A. .

When the protector 4 is mounted on the side sill portion 57, the electrical harness 59 is arranged along the vertical wall 58 on the shoulder surface 57c of the sill inner panel 57A, at which time the skirt portion 4e is attached to the sill inner panel 57A. To face. Next, when the clip 5 formed on the inner surface of the skirt portion 4e is press-fitted into the engagement hole on the sill inner panel 57A side, the protector 4 accommodates the electrical harness 59 in the internal space and the shoulder surface 57c. Fixed on top.

Next, when fixing the side terminal portion 53a to the protector 4, first, after laying the floor carpet 53 on the floor panel 56, until the inner surface of the horizontal portion 2a abuts on the upper surface of the horizontal portion 4a. The vertical portion 2b of the mounting retainer 2 is strongly pushed into the locking groove 3. Then, the width of the locking groove 3 is slightly larger at the opening portion than the thickness of the vertical portion 2b of the mounting retainer 2 and gradually becomes smaller than the thickness of the vertical portion 2b toward the bottom. Since the vertical portion 2b has a structure in which the vertical portion 2b can be press-fitted and locked, the vertical portion 2b is locked at the pushed-in position, and is prevented from coming off and fixed. Further, after this, the resin kicking plate 62 is attached from the shoulder surface 57c of the sill outer panel 57B to the inside of the terminal portion 53a.

That is, the kicking plate 62 is a resin molded body, and the lower horizontal wall portion 62a fixedly arranged on the shoulder surface 75c of the sill outer panel 57B and the upper horizontal wall portion 62a are bent upward from one end. Vertical wall 62b, an upper horizontal wall portion 62c bent substantially at a right angle from the upper end of the vertical wall portion 62b, and an abutment wall slightly bent downward from the tip of the upper horizontal wall portion 62c. And a portion 62d. On the lower surface of the lower horizontal wall portion 62a, a clip (not shown) integrally formed with the shoulder surface 57c of the sill outer panel 57B and press-fitted into an engaging hole (not shown) is integrally formed. When the clip of the lower horizontal wall portion 62a is attached to the kicking plate 62 by engaging with the engaging hole of the shoulder surface 57c of the sill outer panel 57B (see Japanese Utility Model Laid-Open No. 2-26949), the sill inner panel 57A is attached. On the side, the abutment wall portion 62d abuts the upper surface of the floor carpet 53, and the abutment wall portion 62d presses the floor carpet 53 to engage the engagement hole 3 with the claw portion 5a of the locking protrusion 5. And the side end portion 53a and the engaging portion are covered.

Therefore, according to the structure of this embodiment, when the vertical portion 2b of the mounting retainer 2 is inserted into the locking groove 3 on the protector 4 side, the vertical portion 2b of the mounting retainer 2 is positioned on the protector 4 side. It is easily press-fitted and locked in the locking groove 3 to prevent the side terminal portion 53a and the mounting retainer 2 from moving. Further, since the mounting retainer 2 is a small piece, the mounting retainer of the conventional structure has a plurality of engaging holes together and is formed into a strip plate shape, whereas the handling and locking operation is smooth. Since it is possible to pull the side terminal portion 53a partially, it is possible to absorb the positional or dimensional accuracy error between the respective members. Since the mounting retainer 2 is fixed to the side terminal portion 53a so as not to fit into the side terminal portion 53a as in the embodiment, appearance and handling are improved before the floor carpet 53 is mounted on the vehicle body.

Although the above embodiment discloses the structure in which the skirt portion 4e is provided with the clip 5 and the clip 5 is press-fitted into the engagement hole on the side of the sill inner panel 57A to be attached, Other structures may be used. Further, although the example in which the locking groove 3 is formed so as to form a part of the inner vertical portion 4b is shown, it may be provided on the outer surface of the inner vertical portion 4b, for example. Thus, the present invention can be variously developed within the scope of the claims.

[0022]

[Effect of device]

 As described above, in the vehicle floor carpet terminal fixing structure according to the present invention, the vertical portion of the mounting retainer is pushed into the locking groove formed on the protector side for locking, so that As you can see, it doesn't come off easily before the kicking plate is attached. This locking operation can be performed efficiently because the locking groove is opened upward and the vertical portion of the mounting retainer is simply pushed. Also, since the mounting retainer is a small piece, it is easy to engage with the long strip-shaped mounting retainer of the conventional structure, and even if there is a dimensional variation between each member, it is absorbed by the elasticity of the carpet. This makes it possible to reduce the dimensional accuracy of each member. However, the engaging structure is simple and the molding die can be simplified.
