Description

  The present invention relates to an interior part and a work tool for manufacturing the interior part, and more particularly to a support structure for a skin material that covers the surface of an interior part such as a console box provided inside an automobile.

  Various interior parts are provided in the interior of a vehicle such as a passenger car in order to enhance the convenience of the vehicle and improve the design. For example, a console box for storing small items is installed between the driver's seat and the passenger seat, and this console box generally has a box-shaped console box main body with an opening on the upper surface for taking in and out things. A lid for closing the upper surface opening is provided. The lid is attached to one end portion or one side edge portion of the console box main body portion via a hinge so as to be freely opened and closed.

  In recent years, such interior parts often have a structure in which a core material, which is a resin molded product, is covered with a skin material such as cloth or synthetic leather. This is to improve the design of the interior parts by covering the resin core material with a skin material while forming the core material as a casing with a resin that is lightweight, high-strength and can be molded at low cost. Covering with a skin material to improve the appearance and feel and imparting an excellent texture contributes to improving the design of the interior of the vehicle, and also increases the commercial value of the car from the design aspect. For the same reason, the same structure in which the core material is covered with the skin material is also adopted for various interior parts such as the center console and the door lining.

  In order to attach the skin material to the core material, conventionally, for example, a skin material that has been sewn in accordance with the shape of the part, such as a bag shape, is placed so as to wrap the core material while applying tension (tensile force). Fold the hem part back to the back side of the lid (turn around the inner side) and fix it to the back side (inner side) of the core material. For example, an adhesive or a tucker is used for fixing the skin material.

  Further, the following patent documents disclose such a skin material support structure.

Japanese Utility Model Publication No. 4-7954 Utility Model Registration No. 2527224 Japanese Utility Model Publication No. 3-94342 Japanese Utility Model Publication No. 1-89249 Japanese Utility Model Publication No. 1-132447 JP 2011-143782 A

  By the way, the conventional structure for fixing the skin material to the core material has the following problems, and there is still room for improvement.

  First, in the method using an adhesive, after the adhesive is applied to the back surface of the core material, the skin material is put on the core material and the edges are attached manually, but the tension is applied without slack. In order to bond in such a manner that it is taut, it is not possible to apply the skin material immediately after applying the adhesive, and it is necessary to wait for the adhesive to become semi-dry and then affix it. For this reason, work takes time. In addition, it is not always easy to cleanly adhere the skin material so that the bonded portion does not shift and wrinkles are generated on the surface.

  In addition, relying on an adhesive for all the fixing points may be exposed to a high in-vehicle temperature, and the adhesive points may loosen during use for many years, and the skin material may become loose.

  Furthermore, in recent years, it has been pointed out that as a sick car syndrome, a chemical substance contained in an adhesive used for the interior of an automobile as well as a house can cause allergies such as atopic dermatitis. On the other hand, if the use of the adhesive can be suppressed, such a problem can be dealt with. Although it is possible to switch to an adhesive that does not contain components that may cause the cause, it is difficult to completely identify all the causative substances, and from a cost standpoint, changes to other fixing methods and other fixing methods It is desired to reduce the amount of adhesive used in combination.

  On the other hand, according to the tucker, there is no need to wait for the adhesive to dry, and it can be fixed immediately. However, if there is a case where the tucker is broken and it is placed on the thin part of the core material, the needle of the tucker may protrude to the surface side of the lid, which causes a decrease in yield and safety. Anxiety remains.

  On the other hand, in the said patent document, the structure which latches the edge part of a skin material using a hook is taken (for example, refer to the said patent document 1 and patent document 2). However, in such a method described in the literature, a large number of hooks are required to fix the flexible skin material so that the surface does not wrinkle, and the work of hanging the skin material on each of these requires time and is troublesome. . In addition, although there are a plurality of pieces, the support is discrete (fluctuated) only by the hooks, so it is not easy to keep the skin material stretched cleanly.

  The invention described in Patent Document 6 has been proposed by the present applicant in order to improve the conventional support structure for the skin material as described above. As a result, an excellent support structure was obtained.

  The above problems are also common to various interior parts having the same structure including the core material and the skin material.

  Accordingly, an object of the present invention is to reduce the amount of adhesive used or fix the skin material without using the adhesive to obtain a good finish of the interior part, and to improve the workability of mounting the skin material. is there.

  In order to solve the above problems and achieve the object, the interior component according to the present invention is an interior component including a rigid hard core material and a skin material covering the core material, and the skin material is A skin body portion covering the outer surface of the core material; and a hem edge portion that is wound around the inner surface side of the core material and supports the skin material to the core material, the hem edge portion of the skin material A plurality of locking holes drilled so as to be arranged along the outer edge, a bottom edge base end portion located on the skin body side from the locking hole, and extending from the locking hole to the outer edge side of the skin material. A plurality of bridging portions that are formed between the adjacent hem edge tip portions and the adjacent locking holes and the locking holes, and connect the hem edge base end portions and the hem edge tip portions, The core material extends along the peripheral edge of the core material on the inner surface (back surface) side of the core material and can fix the hem edge of the skin material. A plurality of slits that include a wall, the base end of which is fixed to the inner surface (back surface) of the core material, and the bridge portion of the skin material can be sandwiched at the top And a plurality of engagement wall portions that are formed between the adjacent notch grooves and penetrate the locking holes when the bridging portion is sandwiched between the notch grooves, The core material is covered with the skin main body so that an edge is wound on the inner surface (back surface) side of the core material, the bridging portion is inserted into the cut groove, and the engagement is performed in the engagement hole. By inserting a wall portion, the hem edge portion was fixed to the locking wall, and the skin material was supported by the core material.

  In the interior part according to the present invention, it is produced by covering the core material with a skin material so as to cover the surface of the core material, and supporting the peripheral edge portion of the skin material on the peripheral edge portion of the core material, As a means for supporting the skin material, a locking wall formed on the peripheral edge of the inner surface side (back surface side) of the core material is provided, and the skin material is fixed by this locking wall.

  Specifically, after covering the outer surface of the core material on the outer surface of the core material and turning the hem edge of the skin material to the back side of the core material, the bridging portion of the hem edge is the core material (locking wall). At the same time, the engaging wall portion of the core material (locking wall) is inserted into the locking hole of the hem edge. As a result, the bridging portion is sandwiched in the cut groove and the hem edge is hooked on the engaging wall portion by the locking hole, and the peripheral portion of the skin material is supported by the locking wall on the back surface of the core material. Note that this skin material mounting operation can be easily performed by pinching the tip of the hem edge, which is the edge of the skin material, with a finger, for example, and pushing it down toward the back surface of the core material.

  As described above, according to the support structure of the present invention, when the skin material is mounted, it is only necessary to push the bridging portion of the skin material into the cut groove of the core material locking wall. There is no need to apply an adhesive or hit a tucker. Therefore, workability in the production of interior parts can be improved.

  Further, in the present invention, the engagement holes and the bridge portions alternately arranged along the periphery of the skin material, and the engagement wall portions and the cut grooves alternately arranged along the periphery of the back surface of the core material corresponding to these are continuously provided. Furthermore, since the skin material can be supported (rather than jumping like a conventional hook), the skin material can be stretched over the core material neatly and a good finish of the interior parts can be obtained.

  On the other hand, contrary to the mounting operation as described above, according to the present invention, it is possible to remove the skin material, which can be said to be an advantageous support structure from this aspect. That is, while the user is using the vehicle installed in the vehicle, the skin material is not usually peeled off, but in order to obtain a better finish during the manufacture or finishing of the interior parts, It may be desirable to correct the looseness or correct a part of it. In such a case, unlike the case of fixing with an adhesive or a tucker, for example, the once-fixed skin material can be removed from the locking groove together with the clasp material. Can be made better.

  Further, when a vehicle is discarded, the parts are generally disassembled and sorted for each part in order to separate and discard each material or to reuse the component constituent materials. At this time, according to the component structure of the present invention, it is easy to remove the skin material from the core material as compared with the conventional structure fixed by an adhesive or a tacker, and a different material (for example, an adhesive or It is possible to prevent the metal tucker needle) from being mixed in.

  In the present invention, the skin material may directly (directly) cover the core material, but other members / materials may be interposed between the skin material and the core material. For example, if an elastic material (cushion material) such as polyurethane, foamed urethane, or sponge is placed between the core material and the skin material, the texture and comfort when touched by the hand with the elasticity of the interior parts. (Cushioning property) can be improved, and the skin material can be tensioned by the elasticity of the elastic material to prevent the skin material from loosening.

  Moreover, it is preferable that the said locking hole has a substantially rectangular horizontally long shape, and the said engagement wall part has a substantially rectangular horizontally long whole shape corresponding to the shape of a locking hole. This is to make it easier to hook the engaging hole in the engaging wall during the manufacturing operation and to support the skin material more securely on the engaging wall of the core material by the wide (horizontal) engaging wall and the engaging hole.

  Moreover, it is preferable to make the width of the bridging portion smaller than the lateral dimension of the locking hole. This is to facilitate insertion of the bridging portion into the cut groove of the locking wall.

  Furthermore, as a preferable aspect, the V-shaped cut is formed at the top of the locking wall at each formation position of the cut groove, toward the cut groove at the top corner of the end of the engagement wall. A slope that is a downward slope is formed. According to such an aspect, a bridge | crosslinking part can be made easy to insert in a notch groove at the time of the mounting | wearing operation | work of a skin material.

  Moreover, in one aspect of the present invention, the end of the engaging wall portion that forms the cut groove has a shape in which the wall thickness gradually decreases toward the center of the cut groove. The reason for this is as follows.

  The core material including the locking wall can be manufactured by integral molding, for example, with a resin. In addition, it is preferable that the cut groove for sandwiching the cross-linked portion of the skin material is formed to have a narrow groove width because the cross-linked portion can be strongly held. However, when the locking wall including the cut groove portion is integrally formed with the core material, if the width of the cut groove is narrowed, the cut groove forming portion of the mold becomes very thin, and the durability of the mold Decreases.

  Therefore, in one aspect of the present invention, the cut groove portion has the shape as described above, that is, each end portion of the adjacent engagement wall portions forming the cut groove is gradually thickened toward the center of the cut groove. Is made thin (a shape in which the ends of the sharp engagement wall portions are abutted with each other / see FIGS. 11A to 11C described later), thereby avoiding the above-described problem of the mold.

  Further, according to another aspect of the present invention, it further includes a back cover that covers the inner surface side of the core material, and the core material includes a top plate portion and a peripheral wall portion that falls from the periphery of the top plate portion, and is locked. The wall extends substantially in parallel with the peripheral wall portion of the core material, thereby forming a fitting groove between the locking wall and the peripheral wall portion, and the back cover includes the fitting groove. In the state in which the skin material is supported by the core material, the base of the hem edge is accommodated in the fitting groove, and the back cover is pressed so as to press down the base edge of the hem edge. The fitting edge is inserted into the fitting groove.

  According to such a component structure, in addition to the support by the notch groove and the bridging portion, the engagement wall portion and the locking hole, the bottom edge of the skin material is placed in the fitting groove of the core material by the back cover. It is possible to hold and prevent the skin material from detaching from the engaging wall and the cut groove, so the skin material is more securely fixed to the core material, and the skin material in use is more reliably loosened and detached. Can be prevented.

  Similarly, in order to increase the support strength of the skin material to the core material, the inner surface of the locking wall further includes a plurality of locking pins for hooking and locking the tip of the hem edge, and at the tip of the hem edge. In addition, a plurality of auxiliary locking holes may be further provided that allow the locking pin to pass therethrough and allow the tip of the hem edge to be hooked on the locking pin.

  According to such an aspect, since the auxiliary | assistant latching hole can be used to hook and support the skirt edge front-end | tip part of a skin material on the said locking pin, the support strength of a skin material can be improved. . In particular, some types of interior parts do not have a back cover, and this aspect can be preferably applied to such interior parts. In addition, in this invention, it is also possible to use together this aspect provided with the locking pin, and the aspect provided with the back cover mentioned above (it is provided with both a locking pin and a back cover).

  Further, in the work tool for manufacturing an interior part according to the present invention, the hem edge portion of the skin material is used as a fitting groove (between the peripheral wall portion and the locking wall of the core material) in manufacturing the interior component of the present invention described above. While pushing in, the operation | work which pinches | interposes the bridge | crosslinking part of a skin material in the latching groove | channel of a core material is enabled easily.

  Specifically, the work tool includes a rod-shaped tool body for pushing the hem edge of the skin material into the fitting groove of the core material, and the tool body has a cross-sectional shape having a substantially T-shaped tip. A long plate-shaped abutting plate portion extending in the length direction of the tool main body, and a surface of the tool main body protruding from the front surface of the abutting plate portion so as to be orthogonal to the abutting plate portion. A long plate-like pushing plate portion extending in the length direction, and the width size of the pushing plate portion is made larger than the width size of the fitting groove of the core material (between the peripheral wall portion and the locking wall of the core material). Thus, when the tool main body is inserted into the fitting groove, the edge portion of the pressing plate portion protruding from the front surface of the abutting plate portion is inserted into the cutting groove of the locking wall.

  As described above, the interior part to be used for this tool includes a hard core material having rigidity and a skin material covering the core material, and the skin material has an outer surface of the core material. A covering skin main body portion, and a hem edge portion that is wound around the inner surface side of the core material and supports the skin material on the core material, and the hem edge portion is arranged along an outer edge of the skin material. A plurality of locking holes drilled in this way, a hem edge base end portion located on the skin body part side from the locking hole, and a hem edge tip portion extending from the locking hole to the outer edge side of the skin material And a plurality of bridging portions that are formed between the adjacent locking holes and the locking holes and connect the base end portion of the hem edge and the tip end portion of the hem edge, and the core material is a top plate Part, a peripheral wall part falling from the periphery of the top plate part, and extending along the periphery of the core material on the inner surface side of the core material. A locking wall capable of fixing the hem edge portion of the core material, the locking wall having a base end portion fixed to the inner surface of the core material, and sandwiching a bridging portion of the skin material at the top. A plurality of slits to be enabled, and a plurality of engagements formed between the adjacent slits and the slits and penetrating the locking holes when the bridging portion is sandwiched between the slits And a fitting groove is formed between the locking wall and the peripheral wall portion by extending substantially parallel to the peripheral wall portion of the core member with a space therebetween.

  If the work tool of the present invention is used, at the bridging portion forming position of the skin material (that is, the cut groove forming position of the core material), T So that the tip of the tool body having a letter-shaped cross-sectional shape protrudes, the abutting plate portion is parallel to the outer edge of the skin material (base end portion of the hem edge), and the pushing plate portion is along the bridging portion (bridging portion If the tip of the tool body is pushed into the fitting groove while the back surface of the abutting plate is in contact with the inner surface of the peripheral wall of the core material, the base of the hem edge is pushed by the abutting plate. Is pushed into the fitting groove of the core material. At the same time, the push plate portion of the tool body is inserted into the cut groove as the tool main body advances (enters into the fitting groove). It is pushed into the cut groove of the core material. Along with this, the engaging wall portion of the core material is inserted into the locking hole of the skin material.

  As described above, when the work tool of the present invention is used, the hem edge of the skin material can be quickly and easily supported on the inner surface of the core material, and the skin material can be mounted efficiently.

  The interior parts referred to in the present invention are various parts installed inside a vehicle or the like, and have a structure in which a core material is covered with a skin material. For example, a console box (console box body or lid), a center console, a door lining, an instrument, a pillar, a storage box (a body or lid of the box) installed on a rear seat, an armrest, and the like are included. In addition, the console box described later as an embodiment is typically a container placed between the driver's seat and the passenger seat, but may be placed in the rear seat or other places, There is no particular limitation. For example, the present invention can be widely applied to parts having a structure in which a hard core material is covered with a sheet-like skin material, such as a case with a lid provided on a passenger seat side of a dashboard or inside a door.

[Interior parts]
As shown in FIGS. 1 to 11C, an interior part 11 according to an embodiment of the present invention is a lid of a console box installed between seats 1 and 2 in an automobile, and can store articles therein. The top opening of the box body (console box body) 3 is closed so that it can be opened and closed. The lid 11 is an elastic material arranged so as to cover the core material 12 formed of a hard resin material (for example, polypropylene), and the top plate portion 12a and the peripheral wall portions 12b, 12c, 12d, and 12e of the core material 12. (Sponge material) 13, a skin material 14 that covers the core material 12 and the elastic material 13 to form the surface of the lid 11, and a back lid 15 that covers the inner surface (back surface) side of the core material 12 (FIGS. 8 to 8). 9B / not shown in FIGS. 2 to 3, FIG. 10, etc.).

  The elastic material 13 is interposed between the core material 12 and the skin material 14 so as to soften the feeling when the lid 11 is touched (assuming that the cushion is effective) and is pressed by the skin material 14. It becomes a state (crushed to some extent) and contributes to keeping the skin material 14 in a tension state by the repulsive force.

  In the following description of the embodiment, three-dimensional coordinates (X1-X2, Y1-Y2 and Z1-Z2 axis coordinates) are appropriately shown in the drawing, and Y1 is the forward direction of the automobile with reference to the installation state in the automobile. The direction is “front”, the backward direction Y2 direction is “rear”, the left side X1 direction is “left”, and the right side X2 direction is “right”. The description will be made assuming that the Z1 direction which is the upward direction is “up” and the Z2 direction which is the vertically downward direction is “down”.

  The core material 12 has a substantially rectangular planar shape, and covers a top plate portion 12a that covers the upper surface of the box body 3, and peripheral wall portions 12b to 12e that fall from the front end, rear end, left edge, and right edge of the top plate portion 12a. That is, it has the front wall part 12b, the rear wall part 12c, the left side wall part 12d, and the right side wall part 12e. Locking walls 21 for fixing the skin material 14 are provided inside the peripheral wall portions 12b to 12e. The locking wall 21 has substantially the entire circumference (the front wall portion 12b, the rear wall portion 12c, and the left and right side wall portions) of the peripheral wall portions 12b to 12e so that the periphery (hem edge portion) 30 of the skin material 14 can be fixed. 12d and 12e) are provided in parallel with the peripheral wall portions 12b to 12e at a predetermined interval, and the edge portion (fitting of the back cover 15 is fitted between the locking wall 21 and the peripheral wall portions 12b to 12e. A fitting groove 22 capable of fitting the edge portion 15a is formed.

  The core material 12 is appropriately provided with a pedestal for attaching a hinge for connecting the box body 3 and the lid 11, a reinforcing rib, a pedestal for fixing the back lid 15, and the like. The stop wall 21 is integrally molded together with the pedestal and the rib together with the top plate portion 12a and the peripheral wall portions 12b to 12e by, for example, injection molding.

  A plurality of cut grooves 23 are formed in the locking wall 21 with a certain interval. These cut grooves 23 are formed so as to extend upward (in a direction orthogonal to the top plate portion 12a) from the bottom surface of the locking wall 21 toward the top plate portion 12a of the core material 12, and the groove width is the skin described later. It is narrower than the bridging portion 33 of the material 14, thereby enabling the bridging portion 33 of the skin material 14 to be sandwiched and supported inside the cut groove 23.

  Further, an engagement wall portion 24 is formed between the adjacent cut grooves 23 by forming the cut grooves 23. The engaging wall portion 24 penetrates the hem edge portion 30 (latching hole 34 described later) of the skin material 14 when the bridging portion 33 of the skin material 14 is sandwiched in the cut groove 23, and the edge of the skin material 14 It functions to be supported on the inner surface of the core material 12 so as to be hooked.

  As shown in FIGS. 4 and 6, the lower end of the cut groove 23 for receiving the skin material 14 (the bridging portion 33) (FIGS. 4 and 6 are shown with the lid 11 turned upside down. The upper end is cut out from the lower surface of the locking wall 21 (engagement wall portion 24) so as to cut out the corners of the adjacent engagement wall portions 24 so as to have a V-shape. A slope is formed so as to descend toward the inside of the insertion groove 23. This is to facilitate insertion of the bridging portion 33 of the skin material 14 into the cut groove 23.

  Further, as shown in FIGS. 5 to 11A, the planar shape of the cut groove forming portion, that is, the end shape of the pair of (adjacent) engagement wall portions 24 forming the cut groove 23, is shown in FIG. The shape in which the wall portion 24 gradually decreases in thickness toward the central portion of the cut groove 23, in other words, the sharp ends of the engagement wall portion 24 are abutted against each other and a gap (cut groove) 23) is formed. This is because of the reason for manufacturing the mold as already described. That is, in the present embodiment, the cut groove 23 is formed thin (for example, about 1 mm in width). However, if the parallel end faces are simply abutted without changing the wall thickness of the engagement wall portion 24, The mold part for forming the cut groove 23 becomes a thin plate, the strength is weakened, and the durability of the mold is lowered. Therefore, in order to avoid this, the structure as described above is adopted.

  In addition, the planar shape of the cut groove portion is, for example, as shown in FIGS. 11B to 11C, in addition to a mode in which inclined surfaces are formed on both the front surface side and the back surface side of the engagement wall portion 24 as shown in FIG. In addition, a slope may be formed only on one of the front surface side or the back surface side of the engagement wall portion 24 so that the end portion of the engagement wall portion 24 has a planar shape.

  The skin material 14 is formed by sewing a sheet-like material into a bag shape so as to match the shape of the core material 12 and cover it. The size of the skin material 14 is set to a size such that the skin material 14 is stretched without slack when the core material 12 is covered and the peripheral portion of the skin material 14 is fixed using the locking wall 21. As the material of the skin material 14, for example, cloth, moquette (wool fabric), synthetic leather, natural leather, resin sheet, or other flexible sheet-like material can be used.

  In the lower edge portion (hem edge portion) 30 of the skin material 14, a bridging portion 33 and a locking hole 34 are provided corresponding to the cut groove 23 and the engaging wall portion 24 of the core material 12, respectively. Specifically, the locking hole 34 is formed so as to be disposed at a position where the engaging wall portion 24 of the core material 12 is formed and to be able to insert the engaging wall portion 24. On the other hand, the bridging portion 33 to be formed between the adjacent locking holes 34 and the locking holes 34 is arranged at the position where the cut groove 23 is formed.

  Strictly speaking, the width dimension of the bridging portion 33 is the width of the arrangement direction of the locking holes 34 (direction parallel to the edge of the skin material 14) and the extending direction of the locking wall 21. Therefore, the width dimension of the locking hole 34 is slightly smaller than the width dimension of the engaging wall portion 24. However, since the skin material 14 has flexibility (stretchability), it is possible to push the bridging portion 33 into the cut groove 23 and push the engagement wall portion 24 into the locking hole 34. The 14 edge portions can be favorably supported by the locking wall 21.

[Manufacturing process and work tools]
The mounting work of the skin material 14 to the core material 12 will be described together with a tool suitable for the work.
In order to attach the skin material 14 to the core material 12, the skin material 14 is put on the core material 12 provided with the elastic material 13 as shown by the arrows in FIGS. 2 and 3, and then the skin material as shown in FIG.
