[Industrial applications]
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an ornament with gathers for a vehicle which is mounted inside a vehicle such as a door trim of a vehicle, and a method for manufacturing the same.
[0002]
[Prior art]
For example, an ornament is mounted inside a door trim of a vehicle in addition to an armrest and a door pocket. Many ornaments have a configuration in which the surface of a substrate in which pads are stacked on a plate material such as an iron plate is covered with a synthetic leather skin. As shown in FIGS. 6, 7, and 8, there is a type with a gather that elaborates a design in which a gather 102 is formed on a skin 101. FIG. The ornament in which the gather 102 is attached to the outer skin 101 is provided with a unique tone produced by the gather 102 as compared with the monotonous flat surface of the skin, thereby enhancing the value of the ornament as a decorative part. Conventionally, such ornaments with gathers are formed by forming a gather 102 on the upper and lower surfaces of a skin 101 in advance by sewing with a sewing machine as shown in FIG. It is manufactured by inserting it while pulling it so that unnecessary wrinkles are not formed on the side surface.
[0003]
[Problems to be solved by the invention]
The conventional ornament with gathers described above has a problem that the production is troublesome and the quality control is troublesome, so that the cost is high. That is, the synthetic leather used as the outer skin 101 is not so flexible, and has a relatively high rigidity as a sheet-shaped member. Therefore, it is difficult to form the gathers 102 even by pinching in the first place. In addition, since the terminal portion of the skin 101 with the gather 102 is strongly pulled so that unnecessary wrinkles are not generated when the skin 101 is stretched, the gather 102 is extended and tends to disappear. Therefore, the proportion of defective products is much higher than that of a monotonous ornament with no gathers 102.
[0004]
Then, this invention is made in order to solve the said conventional problem mentioned above, and the subject is to improve the appearance of the ornament with a gather by a stable gather, and to reduce the cost of the ornament with a gather. Another object of the present invention is to provide a manufacturing method for easily and easily manufacturing a ornament with gathers.
[0005]
[Means for Solving the Problems]
In order to achieve the above object, an invention according to claim 1 is an ornament with a gather for a vehicle which forms a decorative surface on the inside of a vehicle such as a door trim of a vehicle in which a skin is adhered to a base material and the skin is gathered. The base material is provided with a corrugated (corrugated) resin plate having a corrugated (corrugated) resin plate having a corrugated shape for forming a gather on the surface of the pad. It is characterized by having gathers that are closely bonded to the surface and are formed by the corrugations of the pads.
[0006]
In order to achieve the above object, an invention according to claim 2 is an ornament with a gather for a vehicle which forms a decorative surface on the inside of a vehicle such as a door trim of a vehicle in which a skin is adhered to a base material and the skin is gathered. In the manufacture of the above, a skin in a material state without gathers is adhered to the surface of a pad constituting a part of the base material, and a thin, gather-forming corrugation constituting another part of the base material is formed on the back surface. A layered body is formed by superimposing a corrugated resin plate, and the layered body is fitted to upper and lower weld types each having a contact surface corresponding to the corrugation of the resin plate. It is characterized in that the pad and the resin plate are welded to each other in a state of close contact with each other at their peripheral edges, and that the outer skin is formed with a gather following the corrugation for forming the gather.
[0007]
[Action]
According to the first aspect, the gather is formed into the skin by the corrugation of the pad by the resin plate irrespective of sewing by the close bonding of the skin to the base material.
[0008]
In the second aspect, the outer skin is formed on the outer skin by welding the outer skin, the pad and the resin plate in a state of being in close contact with each other by the upper and lower weld types each having a contact surface corresponding to the corrugation of the resin plate. Gather is formed following the wave shape for use.
[0009]
【Example】
An embodiment of the present invention will be described below with reference to FIGS.
FIGS. 1 to 4 show an ornament 1 with gathers for a door trim of a vehicle according to an embodiment of the present invention. The feature of the ornament 1 with gathers is that the gathers 2 are formed by molding, so to speak, without using sewing such as pinching. That is, the ornament 1 with gathers attached to the door trim 3 has a configuration in which a synthetic leather skin 5 made of vinyl chloride or the like is adhered to the surface of a base material 4, and the vertical gathers 2 are formed on the skin 5. Is formed. As shown in FIG. 2, the base material 4 was lined on one side of a resin impregnated pad 6 with a thin, corrugated, resin plate 8 made of polyethylene or the like having a thickness of about 1.0 mm and having a corrugation 7 for forming a gather. In the configuration, the surface of the soft resin-impregnated pad 6 has a waveform that is lined up in the vertical direction by the backed resin plate 8. The skin 5 is tightly bonded to the surface of the resin-impregnated pad 6 having a corrugated shape by using an adhesive, and is thermally fused to the base material 4 at the peripheral edge 9 to be integrated with the base material 4. The gathers 2 of the skin 5 are formed in a uniform and stable form so as to follow the waveform appearing on the surface of the resin-impregnated pad 6 as they are, and have a good appearance.
[0010]
The mounting of the ornament 1 with gathers on the door trim 3 is performed by a boss 11 formed at a necessary portion of a frame portion 10 having a U-shaped cross section integrally formed on the periphery of the resin plate 8 as shown in FIGS. To the door trim 3 side. That is, on the door trim 3 side, a spring nut 12 is attached to the back of the boss fitting portion, and the boss 11 is gripped by the spring nut 12 as the boss 11 is fitted. In FIGS. 3 and 4, M indicates a decorative molding.
[0011]
Next, a method of manufacturing the ornament 1 with gathers described above will be described. The remarkable difference from the conventional method of manufacturing the ornament with gathers is a method of forming the gathers 2 on the skin 5 and a method of attaching the skin 5 to the base material 4. That is, first, the skin 5 in a material state cut into a required shape and size without the gathers 2 is adhered to the surface of the resin impregnated pad 6 constituting a part of the base material 4 using an adhesive. Subsequently, on the back surface of the resin impregnated pad 6, a thin corrugated resin plate 8 having a corrugated waveform 7 for forming a gather forming another part of the base material 4 is overlapped to form a layered body. Thereafter, as shown in FIG. 5, this layered body is fitted to upper and lower weld dies 14 and 15 each having a contact surface 13 corresponding to the corrugation 7 of the resin plate 8, and the skin is formed by the weld dies 14 and 15. 5, the resin impregnated pad 6, and the resin plate 8 are welded together at their peripheral edges 9 in a state of close contact. As a result, the three members are all formed as having the same waveform as the resin plate 8, and the gathers 2 are formed on the skin 5 following the corrugations 7 for forming the gathers.
[0012]
According to the manufacturing method of the ornament 1 with gathers, it is not necessary to form the gathers 2 on the fairly rigid skin 5 by pinching and sewing, and the manufacturing is easy because the skin 5 is not attached while being stretched. The quality is stable and the cost is reduced. The gathers 2 of the skin 5 are molded so as to be uniform and the quality is stable, so that the ratio of defective products is significantly reduced. Although the above-described embodiment has been described with reference to the case of a synthetic leather skin, the skin is not limited to the synthetic leather, and the present invention can be applied to a rigid or non-rigid skin.
[0013]
【The invention's effect】
As is apparent from the above description of the embodiment, according to the first aspect of the present invention, the gathers are formed on the skin by the waveform of the pad formed by the resin plate, not by sewing, due to the close bonding of the skin to the base material. The uniformity and stability of the gather shape are improved, and a low-cost ornamented ornament with good appearance can be obtained.
[0014]
According to the second aspect of the present invention, it is not necessary to form a gather by sewing, and it is possible to easily and easily manufacture an ornament with a stable appearance having a stable appearance and a reduced cost.
