Description

  The present invention relates to an interior skin terminal processing structure in which a terminal portion of an interior skin is fixed to a core material.

  Conventionally, when fixing the end portion of the skin to the core material, the skin is heated and melted at the position of the projection provided on the back surface side of the core material to form a hole, and the hole penetrates the projection. There is one that forms a head part that engages with a hole by heating and melting the tip part (see, for example, Patent Document 1).

Japanese Patent No. 396618

  However, such a conventional terminal treatment structure of the skin is heated and melted to form a hole in the skin, and is heated and melted to form a head at the tip of the protrusion. For this reason, a process of heating and melting is required in addition to the process of forming the skin and the core material, and a lot of equipment, cost and work time are required.

  Therefore, the present invention provides a terminal treatment structure for interior skin that can fix the terminal portion of the skin to the core material in a short time without using any new equipment in the manufacturing process.

  In the terminal treatment structure for an interior skin according to the present invention, a tab portion provided with a latch hole is projected from a terminal portion of the skin, while a projection portion for inserting and engaging the latch hole with a core member. Is provided. In addition, a tongue having a contact surface that follows and contacts the side surface of the protrusion is provided in a projecting manner in the peripheral portion of the retaining hole. And when attaching a skin, the contact surface of the said tongue part is closely_contact | adhered to the side surface of the said projection part, inserting the latching hole of the said tab part in the said projection part.

  According to the present invention, the terminal portion of the skin can be attached to the core material by inserting the retaining hole of the tab portion protruding from the terminal portion of the skin into the protrusion provided in the core material. At this time, since the contact surface of the tongue protruding from the peripheral portion of the retaining hole is in close contact with the side surface of the projection, the frictional resistance between the tongue and the projection increases, and the tab portion is separated from the projection. It is difficult to come off, and the skin can be fixed more reliably.

  Accordingly, since the tab portion and the projection portion can be formed at the time of forming the skin and the core material, the terminal portion of the skin can be cored in a short time without newly using equipment and jigs in the manufacturing process. It can be fixed to the material.

The core material 2 is formed in substantially the same shape as the skin 1 and is disposed on the back surface of the skin 1. The skin 1 has a decorative surface and is formed of a flexible soft resin or the like. The core material 2 is formed of a hard resin having high rigidity, such as a fiber reinforced resin.

  As shown in FIG. 2, a skin-side bent edge 1 a that bends to the back surface side is formed on the terminal peripheral edge portion 1 </ b> E (see FIG. 1) of the skin 1. Similarly, as shown in FIG. 2, a core material side bent edge 2 a that bends to the back surface side is formed at the peripheral edge portion of the core material 2. In this case, the skin side bent edge 1 a is bent substantially perpendicular to the general surface of the skin 1. The core material side bent edge 2 a is bent at an obtuse angle with respect to the general surface of the core material 2. And when the core material 2 is covered with the skin 1, the skin side bent edge 1a is covered on the outer side of the core material side bent edge 2a.

  A plurality of tab portions 11 project from the tip of the skin-side bent edge 1a at appropriate intervals in the length direction thereof. The tab portion 11 is molded at the same time as the skin 1 is molded, and has a rectangular shape as a whole and protrudes from the tip of the skin bent edge 1a. The base end portion 11a of the tab portion 11 is formed thinly over a predetermined section, and the tab portion 11 can be bent as a whole from the base end portion 11a.

  Further, the tab portion 11 is a distal end portion 11b whose tip end side is thicker than the base end portion 11a formed to be thin, and the distal end portion 11b is slightly thinner toward the distal end. It is inclined to. A rectangular hooking hole 12 is formed at the center of the tip portion 11 b of the tab portion 11.

  On the other hand, as shown by an arrow a in FIG. 4, a protruding portion 21 protrudes from the back surface of the core member 2 at a position corresponding to the latch hole 12 when the tab portion 11 is bent from the base end portion 11 a. ing. A plurality of protrusions 21 are provided corresponding to the respective tab portions 11, and the latch holes 12 are inserted and engaged with the respective protrusions 21. The protruding portion 21 is a protruding portion 21 having a tapered cylindrical shape whose cross section decreases toward the tip.

  Further, the tongue portion 13 is integrally protruded along the peripheral portion of the latch hole 12 of the tab portion 11, that is, along the side 12 a on the distal end side of the latch hole 12 that is rectangular in this embodiment. . As for this tongue part 13, the surface (inner side surface) which opposes the inner side of the latching hole 12 becomes the contact surface 13a which follows the side surface 21a of the projection part 21, and contacts.

  That is, in the present embodiment, the tongue portion 13 is inclined in a direction along the inclined side surface 21a of the protruding portion 21 so that the contact surface 13a contacts the side surface 21a of the protruding portion 21 having a tapered shape. At this time, it is preferable that the tongue portion 13 is inclined slightly larger than the side surface 21a of the protruding portion 21, and the tongue portion 13 is pressed against the side surface 21a. In the present embodiment, the tongue portion 13 is provided so as to protrude outside the tab portion 11 (upward in FIG. 3).

  In order to attach the skin 1 to the core material 2, as shown in FIG. 4, the core material 2 is covered with the skin 1 while matching the skin side bent edge 1 a and the core material side bent edge 2 a. At this time, a plurality of ribs 1b for receiving the core-side bent edge 2a formed at an obtuse angle are provided at appropriate intervals inside the skin-side bent edge 1a formed at a substantially right angle.

  In the state where the core material 2 is covered with the skin 1 as described above, as shown in FIGS. 2 and 4, the tab portion 11 stands up so as to extend substantially from the skin side bent edge 1 a, and from this standing state, The tab portion 11 is bent inward of the core material 2 as indicated by an arrow a. Then, as shown in FIGS. 3 and 5, the retaining hole 12 of the tab portion 11 is inserted toward the root from the tip of the protruding portion 21, and inserted and engaged in close contact with the side surface 21 a of the protruding portion 21. Is done.

  In this insertion engagement state, the four sides of the rectangular retaining hole 12 are in contact with each other in the tangential direction around the side surface 21 a having a circular cross section of the protrusion 21. Thereby, the terminal peripheral edge part of the skin 1 can be fixed to the peripheral edge part of the core material 2 only by engaging the retaining hole 12 of the tab part 11 so as to be hooked on the protruding part 21 of the core material 2. .

  At this time, as shown in FIG. 6A, the tongue portion 13 protruding from the side 12 a on the front end side of the retaining hole 12 to the outside of the tab portion 11 has its contact surface 13 a as the side surface 21 a of the protrusion portion 21. Are in a state of following the initial state of the two-dot chain line (shown by a solid line in the figure). Thereby, the frictional force between the tongue portion 13 and the projection portion 21 is increased, and the tab portion 11 can be efficiently prevented from coming out of the projection portion 21, and as a result, the fixing force of the skin 1 can be further increased.

  Further, in the present embodiment, the tongue portion 13 protrudes in the direction of the outer surface 11 c of the tab portion 11. Accordingly, as shown in FIG. 6B, when the tab portion 11 slides up the protruding portion 21 for some reason, the side surface of the protruding portion 21 is indicated by the solid line-shaped tongue portion 13 as indicated by a two-dot chain line. It acts in the direction of biting into 21a. 6 (a) and 6 (b), the tongue portion 13 indicated by a two-dot chain line indicates a natural state before the retaining hole 12 is inserted into the projection portion 21, and the tongue portion 13 indicated by a solid line is A state in which the retaining hole 12 is inserted into the protrusion 21 and follows the side surface 21a is shown.

  As described above, according to the terminal treatment structure for the interior skin of the present embodiment, the tab portion 11 is integrally projected on the peripheral edge portion of the skin 1, and the projection portion 21 is provided on the core material 2. Projected. And the terminal peripheral part of the skin 1 can be easily attached to the core material 2 by inserting the latching hole 12 provided in the tab part 11 in the projection part 21.

  At this time, the contact surface 13a of the tongue portion 13 protruding from the hole peripheral portion of the retaining hole 12 follows and closely contacts the side surface 21a of the protrusion portion 21, so that the frictional resistance force between the tongue portion 13 and the protrusion portion 21 is increased. Can be increased. Thereby, the tab part 11 can be made hard to remove | deviate from the protrusion part 21 in the removal direction, and fixation of the skin 1 can be made more reliable.

  Therefore, since the tab part 11 and the protrusion part 21 can be integrally formed at the time of molding the skin 1 and the core material 2, the terminal of the skin 1 can be used in a short time without using any new equipment in the manufacturing process. The peripheral edge can be fixed to the core material 2.

  In addition, according to the present embodiment, the protruding portion 21 has a tapered shape whose cross section decreases toward the tip, so that the latch hole 12 of the tab portion 11 can be easily inserted into the protruding portion 21, and the skin 1 is fixed. Work can be done more easily.

  Furthermore, according to this embodiment, since the tongue portion 13 protrudes in the direction of the outer surface 11c of the tab portion 11, when the tab portion 11 tries to slide up the protrusion portion 21 for some reason, the tongue portion 13 protrudes. Since it acts in the direction of biting into the side surface 21a of the portion 21, it is possible to efficiently prevent the tab portion 11 from sliding up.

  By the way, as shown in FIG. 7A, the tongue portion 13 can project in the direction of the inner surface 11 d of the tab portion 11. In this case, however, the contact surface 13a of the tongue portion 13 follows the side surface 21a of the projection portion 21 in a state where the retaining hole 12 is inserted at the normal position of the projection portion 21 as shown in FIG. Due to the close contact, a sufficient frictional resistance can be obtained. In the figure, a tongue portion 13 indicated by a two-dot chain line indicates a natural state before the retaining hole 12 is inserted into the protruding portion 21, and a tongue portion 13 indicated by a solid line indicates that the retaining hole 12 is the protruding portion. The state which inserted in 21 and followed the side surface 21a is shown.

  On the other hand, as shown in FIG. 7B, when the retaining hole 12 is raised, the tongue portion 13 is lifted from the side surface 21a of the protruding portion 21, so that sufficient frictional resistance can be obtained. There is a risk that it will not be possible. Thereby, it is preferable that the tongue portion 13 protrudes in the direction of the outer surface 11c as shown in the above-described embodiment with respect to the phenomenon of the latching hole 12 rising.

  By the way, although the terminal processing structure of the interior skin of the present invention has been described by taking the above embodiments as examples, the present invention is not limited to these embodiments, and various modifications can be made without departing from the scope of the present invention.
