Description

  The present invention relates to a vehicle deck board that closes a storage opening provided on a floor of a vehicle body and constitutes a part of the floor of the vehicle body.

For example, as shown in FIG. 6, a storage space 3 is provided in a part of the floor 2 of the luggage room 1 in a rear luggage room (called a luggage room) behind the rear seat of the car. The storage opening 4 may be closed with a removable deck board 5 in some cases.
Conventionally, as a structure of this type of deck board, a floor lid body described in Patent Document 1 or a luggage floor trim described in Patent Document 2 is known.

  The floor lid body described in Patent Document 1 is composed of a plate-like base body having a hollow inside and a mat member attached to the surface of the base body. A hollow portion is formed along the side end edge of the base body, and a long mounting hole is formed in the end surface portion of the side end edge directly or through the protruding edge portion. Note that the mat member is bonded to the surface of the base body, and the terminal portion is fitted and fastened in the attachment long hole of the base body.

  The luggage floor trim described in Patent Document 2 includes a double core material composed of an upper core material and a lower core material, and a skin material adhered to the surface of the double core material. The edge of the skin material is folded back along the end surface of the lower core material of the double core material, and is adhered and fixed to the peripheral flange surface of the lower core material.

Utility Model Registration No. 2519479 Japanese Patent Laid-Open No. 10-44880

However, the structures described in Patent Documents 1 and 2 described above have the following problems.
In the floor lid body described in Patent Literature 1, when the mat member is fixed to the base body, the end portion of the mat member must be folded back along the end surface portion of the base body, and then fitted into the mounting long hole. Since the peripheral wall of the hole is substantially perpendicular to the mounting oblong hole, it is difficult to perform the fitting operation. For example, even if the end portion of the mat member is bent along the end surface of the base body with a tool such as a screwdriver or a scraper, it is difficult to insert the tip into the mounting slot from the state as it is. Difficult to do.

  In the luggage floor trim described in Patent Document 2, when the skin material is fixed to the double core material, the skin material is peeled off only by folding the edge of the skin material along the end surface of the lower core material of the double core material. Therefore, after applying an adhesive to the edge of the skin material, it must be adhered and fixed to the peripheral flange flange surface of the lower core material. For this reason, when adhesive force becomes weak, an edge will peel and the problem that an external appearance is impaired arises.

  An object of the present invention is to provide a vehicle deck board that can easily and surely attach a skin material to a substrate and that also has a good appearance.

  A vehicle deck board according to the present invention is a vehicle deck board that closes a storage opening provided on a floor of a vehicle body and constitutes a part of the floor of the vehicle body. The vehicle deck board is mounted on a base and the surface of the base. The base body has a groove along the end surface longitudinal direction at an intermediate position in the end face thickness direction of the base body, and the end surface on the back side of the substrate from the groove is the end face formed with the groove. The outer surface of the substrate is projected from the groove to the substrate surface side end surface portion, and the skin material has a portion corresponding to the surface of the substrate bonded to the surface of the substrate via an adhesive, and an edge of the substrate. It is characterized by being press-fitted and fixed in the groove.

According to this invention, in order to fix the skin material to the substrate, the skin material is bonded to the surface of the substrate via an adhesive, and then the edge of the skin material is pressed into the groove of the substrate and fixed.
In this case, a groove along the longitudinal direction of the end surface is formed at the intermediate position in the thickness direction of the end surface of the substrate, and the end surface on the back side of the substrate from the groove is the end surface on the substrate surface side from the groove. Since the tool protrudes to the outside of the base with respect to the part, a tool such as a scraper is applied to the edge of the skin material, the edge of the skin material is folded back to the end surface on which the groove of the base is formed, and the tip of the tool is It is applied to the substrate rear surface side end surface portion that protrudes outward from the side end surface portion.
When the angle of the tool is further tilted from this position (when the tool is tilted so that the angle of the tool gradually becomes parallel to the groove), the edge of the skin material folded back to the end face is inserted into the groove. Therefore, the tool is moved along the end face direction of the base body in this posture. Then, the edge of the skin material is inserted into the groove, and is pressed and fixed by being sandwiched between the grooves. Therefore, the skin material can be easily and reliably attached to the base. Here, the base surface side end surface portion herein refers to the surface side on which the epidermis is mounted.

In the vehicle deck board of the present invention, the amount of the back surface side end surface portion protruding from the groove to the base surface side from the groove to the base surface side end surface portion is substantially the same as the thickness of the skin material, The dimension is preferably slightly smaller than the thickness of the skin material.
According to the present invention, when the skin material is mounted on the base and the edge of the skin material is inserted and fixed in the groove of the base, the edge of the skin material is substantially the same as the contour shape of the end face on the back side of the base. Or a slightly larger shape. In this state, when the vehicle deck board is mounted in the storage opening of the vehicle, the vehicle can be fitted into the storage opening without any gap.

In the vehicle deck board of the present invention, it is preferable that the inner surface on the surface side constituting the inner wall of the groove is formed as an inclined surface that gradually inclines toward the surface of the substrate as it goes toward the end surface of the substrate.
According to the present invention, a tool such as a scraper is applied to the edge of the skin material, the edge of the skin material is folded back to the end surface on which the groove of the base is formed, and the tip of the tool is moved outward from the end surface on the base surface side. Since the tool can be tilted at an angle at which the tip of the tool can be easily inserted into the groove when received by the protruding end face of the back surface of the base, the edge of the skin material can be easily inserted into the groove of the base.

In the vehicle deck board according to the present invention, it is preferable that the end surface of the base surface side of the groove is formed in a projecting circular arc surface toward the outside of the base.
According to the present invention, when the edge of the skin material is folded back to the end face while squeezing along the surface of the base, the base surface side end face part projects from the groove toward the outside rather than the base back side end face part. Since it is formed on the arcuate surface of the shape, stress is not concentrated on the edge of the skin material, and damage and the like can be reduced.

In the vehicle deck board according to the present invention, it is preferable that a width of the groove is narrower than a thickness of the skin material.
According to this invention, since the width of the groove is formed narrower than the thickness of the skin material, when the edge of the skin material is inserted into the groove, the leading edge of the skin material is press-fitted into the groove Because it is inserted in, it is hard to come off.

In the vehicle deck board according to the present invention, it is preferable that an end surface portion on the back surface side of the substrate is formed on a flat surface substantially orthogonal to the back surface of the substrate.
According to the present invention, when the vehicle deck board is mounted in the storage opening of the vehicle, the end surface on the back side of the base body comes into contact with and fits into the storage opening from the groove, so that the vehicle can be mounted without a gap. The vehicle deck board is less likely to generate vibration even when it is running.

In the vehicle deck board according to the present invention, the base is formed in a flat rectangular shape, and a pair of end surfaces facing the base are provided with the structure according to any one of the first to sixth aspects. It is preferable that a cap is fitted on the other pair of opposing end faces, and a clamping protrusion is formed on the cap so as to sandwich the edge of the skin material with the base.
According to this invention, the pair of facing edges of the skin material are inserted and fixed in grooves provided on the pair of facing end surfaces of the base body, and the other pair of facing edges of the skin material are attached to the base body. Since it fixes in the state pinched | interposed between the clamping protrusion edge of the cap to be fitted, and a base | substrate, all the outer periphery can be fixed reliably. In addition, since these outer peripheral edges are not exposed to the outside, it is possible to finish the appearance well.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
FIG. 1 is an exploded perspective view of the vehicle deck board according to the present embodiment, and FIG. 2 is a cross-sectional view of the vehicle deck board. The vehicle deck board of the present embodiment is a vehicle deck board that closes the storage opening 4 provided in the floor 2 of the vehicle body and constitutes a part of the floor 2 of the vehicle body, as in FIG. 10, a skin material 20 attached to the surface of the base body 10, and a pair of caps 30 detachably fitted to the end face of the base body 10.

  The base 10 is integrally formed in a planar rectangular plate shape by extrusion molding of aluminum. Specifically, an upper wall 11 and a lower wall 12 formed in parallel with each other at a predetermined interval, and a pair of side walls 13 formed between a pair of opposing side surfaces between the upper wall 11 and the lower wall 12. And four rib walls 14 formed in parallel with the side wall 13 between the upper wall 11 and the lower wall 12.

As shown in FIG. 3 (enlarged sectional view), each side wall 13 is provided with a groove 15 along the side wall direction (end face direction) at an intermediate position in the thickness direction of the base 10.
Of the side walls 13 on which the grooves 15 are formed, the lower side wall portion 13A serving as the end surface on the back side of the substrate from the grooves 15 and the upper side wall portion 13B serving as the end surface portion on the substrate surface side from the grooves 15 It protrudes outside. This protrusion amount T1, that is, the protrusion amount T1 of the lower side wall portion 13A from the end surface of the upper side wall portion 13B is formed to have a dimension that is substantially the same as the thickness of the skin material 20 or slightly smaller than the thickness of the skin material 20. Yes. Further, the lower side wall portion 13 </ b> A is sized to fit into the storage opening 4, and is formed on a flat surface that is substantially orthogonal to the back surface (lower wall 12) of the base body 10.

The groove 15 is formed horizontally from the side wall 13 toward the inside of the base body 10, and includes a back-side inner wall surface 15A, a front-side inner wall surface 15B, and a bottom inner wall surface 15C connecting these at the back. The back side inner wall surface 15 </ b> A is formed in parallel with the lower wall 12. The front-side inner wall surface 15B is formed in parallel with the back-side inner wall surface 15A at the back, and is an inclined surface that gradually inclines toward the surface side (upper wall 11 side) of the substrate 10 from the intermediate portion toward the side wall 13 of the substrate 10. After being formed and formed into a projecting circular arc surface from the tip to the outside of the base body 10, it is connected to the upper wall 11.
Here, the groove width dimension T <b> 2 of the groove 15, that is, the groove width dimension T <b> 2 between the back-side inner wall surface 15 </ b> A and the front-side inner wall surface 15 </ b> B constituting the groove 15 is formed narrower than the thickness of the skin material 20. ing. Further, the depth dimension T3 of the groove 15 has a depth dimension that can absorb the variation in the protruding length dimension of the edge of the skin material 20.

  The skin material 20 is obtained by cutting a material such as carpet, cloth, and non-woven fabric into a planar rectangular shape slightly larger than the planar rectangular shape of the substrate 10, and a portion corresponding to the surface of the substrate 10 is bonded to the substrate 10 via an adhesive 21. Bonded to the surface, the edge is inserted and fixed in the groove 15 of the base 10.

The cap 30 is detachably fitted to another pair of end faces orthogonal to the pair of side walls 13 in which the grooves 15 of the base body 10 are formed, and has a contour substantially the same shape as the end face of the base body 10. The cap main body 31 has a rectangular frame-shaped fitting portion 32 that protrudes from the inner surface of the cap main body 31.
On the upper surface of the inner surface of the cap body 31, as shown in FIG. 4, a clamping protrusion 33 is formed that sandwiches the edge of the skin material 20 with the base body 10 when the cap 30 is fitted to the base body 10. Has been. The clamping protrusion 33 is formed in a triangular cross section that protrudes in an inclined manner in the protruding direction of the fitting portion 32 from the inner surface of the cap body 31 toward the upper end.

In the above configuration, in order to fix the skin material 20 to the substrate 10, the adhesive 21 is applied to the surface portion of the substrate 10, or the adhesive 21 is applied to the back surface of the skin material 20, and the adhesive 21 is interposed therebetween. After the skin material 20 is bonded to the surface of the substrate 10, the edge of the skin material 20 is inserted into the groove 15 of the substrate 10 and fixed.
For this purpose, as shown in FIG. 5A, a tool 40 such as a scraper is applied to the edge of the skin material 20, and the edge of the skin material 20 is along the side wall 13 in which the groove 15 of the base 10 is formed. And turn it back. At this time, since the upper side wall portion 13B above the groove 15 is formed in a circular arc surface projecting outward, the side wall 13 is squeezed along the surface of the base body 10 while the edge of the skin material 20 is squeezed. Even when it is folded along, the stress is not concentrated on the edge of the skin material 20, and damage and the like can be reduced.

  In addition, when the edge of the skin material 20 is folded back along the side wall 13, the tip of the tool 40 can be received by the lower side wall portion 13A protruding outward from the upper side wall portion 13B. Therefore, it is possible to stably perform the folding operation of the edge of the skin material 20, and it is easy to stably tilt the tool 40 when tilting the posture of the tool 40 in the next work process.

  When the angle of the tool 40 is further tilted from this posture, that is, when the tool 40 is tilted so that the angle of the tool 40 gradually becomes parallel to the groove 15 as shown in FIG. The edge of the skin material 20 folded back along 13B is inserted into the groove 15. At this time, the surface-side inner wall surface 15B constituting the inner wall of the groove 15 is formed on an inclined surface that is gradually inclined toward the surface side (upper wall 11 side) of the base body toward the side wall 13 of the base body 10. The front end of 40 is easy to insert into the groove 15, and therefore, the edge of the skin material 20 is easy to insert into the groove 15 of the base 10.

  Next, the tool 40 is moved along the side wall 13 direction of the base body 10 in this posture. Then, the end edge of the skin material 20 is inserted into the groove 15 and is sandwiched and fixed by the groove 15. Since the width of the groove 15 is narrower than the thickness of the skin material 20, when the leading edge of the skin material 20 is inserted into the groove 15, the leading edge of the skin material 20 is press-fitted into the groove 15. Because it is inserted in the state, it is hard to come off.

Finally, when the cap 30 is fitted to the end surface of the base 10 where the grooves 15 are not formed, the deck board is assembled.
Therefore, the skin material 20 can be easily and reliably attached to the base 10. In addition, the edge of the skin material 20 is not fixed using an adhesive, and the edge of the skin material 20 is inserted into the groove 15, so that the end surface of the vehicle deck board is finished well. be able to.

  The vehicle deck board combined in this way is mounted in the storage opening 4 of the car. Then, as shown in FIG. 3, the lower side wall 13 </ b> A below the groove 15 is fitted into the storage opening 4 of the vehicle, and the outer edge of the skin material 20 is also in contact with the inner surface of the storage opening 4. Therefore, the vehicle deck board can be fitted into the storage opening 4 without a gap. Therefore, the vehicle deck board is less likely to generate vibration even when the vehicle is running.

When the base 10 is molded from resin, the skin material 20 may be integrally formed on the surface of the base 10 when the base 10 is molded, and the edge of the skin material 20 may be inserted and fixed to the base 10 after molding.

  In the above embodiment, the pair of facing edges of the skin material 20 is press-fitted and fixed in the groove 15 of the base body 10. However, the present invention is not limited to this, and the groove 15 is formed on the four end surfaces of the base body 10. The other pair of opposing edges of the skin material 20 may also be press-fitted and fixed in the groove 15 of the base 10.

  In the above-described embodiment, the groove 15 is configured to include the back side inner wall surface 15A, the front side inner wall surface 15B, and the bottom inner wall surface 15C that connects these at the back, but not limited thereto, the bottom inner wall surface 15C Alternatively, the configuration may be such that the inner part is open. In this way, even if the edge of the skin material 20 becomes long, it can be accommodated in the base 10.
