FIG. 2 is a side view showing a mounting position of the opening trim to the body of the automobile. FIG. 3 is a sectional view taken along line AA of FIG. 2 showing a conventional opening trim.

In FIG. 2, an opening trim 60 is generally mounted along the outer edge of a roof side rail from the front and rear door openings of a body 51 of an automobile, for example, from an upper front pillar on a front door 52 side. . As shown in FIG. 3, the conventional opening trim 60 is made of a relatively hard material having a predetermined hardness (for example, about 85 degrees JISA) such as a synthetic resin material such as polyvinyl chloride (PVC) or a rubber material. 61 and the fin portion 62 are integrally formed. The trim portion 61 has a substantially U-shaped cross section, and the end of the door opening 53 of the body 51 can be inserted into the insertion recess 63. A metal insert 64 having a substantially U-shaped cross section substantially the same as that of the trim portion 61 is embedded in the trim portion 61, and a pair of holding lips made of synthetic resin are provided on opposing surfaces of the insertion concave portion 63. The holding lip 65 is elastically contacted with the door opening 53 by the clamping force of the trim portion 61 made of a hard material and the metal insert 64 to hold the opening trim 60 at a predetermined position of the door opening 53. It is supposed to.

The fin portion 62 is integrally formed on one side surface (inside the vehicle) of the trim portion 61 so as to extend in substantially the same direction as the opening direction of the insertion concave portion 63 of the trim portion 61. A shielding recess 66 is formed between the side wall and the side surface. In the shielding recess 66, the end of the interior member of the vehicle such as the ceiling 54 is housed and shielded from the outside, so that the design effect in the vehicle is improved.

In the conventional opening trim 60 configured as described above, the insertion concave portion 63 of the trim portion 61 is inserted into the door opening 53 so as to face the door opening 53, and the outer side surface of the door opening 53 is held by both holding lips 65. Can be assembled along the door opening 53 of the automobile.
Further, by inserting the end of the interior member of the vehicle into the shielding recess 66 inside the fin portion 62 and housing it, the end of the interior member is housed and shielded from the outside, and the design effect in the vehicle is improved. can do.

[0007]

At this time, the opening trim 60 is assembled at the corner of the door opening 53 so as to be bent in accordance with the curvature of the corner. Depending on whether the tip apex is located on the vehicle interior or exterior from the fulcrum F located at the base end of the fin portion 62, the tip apex receives stress on the vehicle interior or exterior due to the curved deformation, and either side thereof Trying to warp back.

However, the conventional opening trim 60
Is configured as described above, the fulcrum F of the fin portion 62 is located at the position closest to the trim portion 61, that is, the lower end position of the inner side surface of the trim portion 61. Therefore,
Regardless of the shape of the fin 62, the top of the fin 62 is
As shown by the two-dot chain line in the drawing, the fin portion 62 is greatly bent toward the vehicle interior at the corner of the door opening 53, and the end of the interior member is completely removed. It cannot be shielded, which may impair the design effect in the car.

Therefore, conventionally, in order to prevent the fin portion 62 from warping inward of the vehicle at the corner portion of the door opening 53, the door opening 53 is mounted before the opening trim 60 is assembled to the door opening 53. Fin 6 corresponding to the corner
It is necessary to heat and soften a portion such as 2 and to add a habit according to the curvature of the corner portion.

In the conventional opening trim, the trim 61 and the fin 62 are integrally formed of a single hard resin material or the like. Difficult to present. As a result, it is also difficult to provide a soft feeling to the design surface of the opening trim and to satisfy the demand for a high-grade feeling as a whole.

In view of the above, the present invention provides an opening trim which ensures sufficient followability of the fin portion at the door opening, imparts a soft feeling to the design surface, and makes it possible to bring out a luxurious feeling as a whole. It is an issue.

SUMMARY OF THE INVENTION An opening trim according to the present invention is a hard resin material or rubber having a substantially U-shaped cross section which can be inserted and held at an end of a door opening (53) of a body (51). A trim portion (11) made of a material, and a fin portion integrally formed of a hard resin material or a rubber material on one side surface of the trim portion (11) so as to extend in substantially the same direction as the opening direction of the trim portion (11). supporting part (14), a resin material or rubber material softer integrally formed as with the outer surface coating, which extends in the opening direction substantially the same direction of the trim portion (11) of the fin support part (14) Fin portion (15) comprising the fin portion (15) and fin portion support
In cooperation with the inner surface of the portion (14), one side of the trim portion 11
And a fulcrum (F2) when curved and deformed in accordance with the curvature of the corner of the fin (15) is formed at a position on the vehicle interior side from the top. It was done.

[0013]

In the present invention, the fin support portion and the fin portion covering the fin support portion integrally extend substantially in the same direction as the opening direction of the trim portion to form a recess between the trim portion and the fin portion. I do. In response to an external force, the fin support portion made of a hard material does not easily bend and deform in the thickness direction, whereas the fin portion made of a soft material deforms relatively easily in the thickness direction. Here, the fin portion is firmly supported on the base end side by the fin portion support portion, and the bending deformation is regulated. Therefore, the fulcrum at the time of the fin portion bending is located at the tip of the fin portion support portion. As a result, as compared with the case where the trim portion and the fin portion are integrally formed of a single hard material, the trim portion and the fin portion are located closer to the vehicle interior with respect to the tip of the fin portion. Moreover, since the fin portion located inside the vehicle is made of a soft material, a soft feeling is given to at least a main portion of the design surface which is visually recognized by the passenger.

Embodiments of the present invention will be described below.

FIG. 1 is a sectional view of an opening trim according to an embodiment of the present invention.

In the drawings, the same reference numerals and symbols as those of the conventional example indicate the same or corresponding parts as those of the conventional example, and therefore, duplicate description will be omitted.

The opening trim 10 of this embodiment includes a trim portion 11 in which an insert 64 is buried as in the conventional example. The trim portion 11 is formed in a substantially U-shaped cross section from a relatively hard resin material or rubber material.
The end of the door opening 53 of the body 51 can be inserted into the inside 2. A pair of holding lips 13 made of a soft resin material or a rubber material are integrally formed on the facing surface of the insertion recess 12 of the trim portion 11, and the holding lip 13 is formed by a clamping force of the trim portion 11 made of a hard material and the metal insert 64. The holding lip 13 is elastically contacted with the door opening 53 to hold the opening trim 10 at a predetermined position in the door opening 53.

A fin support portion 14 made of a relatively hard resin material or rubber material is integrally formed on one side (inside of the vehicle) of the trim portion 11 at a lower end thereof. 12 opening direction), and
The tip is formed at an acute angle. A fin portion 15 made of a soft resin material or a rubber material is integrally formed on an outer surface (inside of the vehicle) of the fin portion support portion 14 so as to extend in substantially the same direction as an opening direction of the insertion concave portion 12 of the trim portion 11, In cooperation with the inner surface of the fin portion support portion 14, a shielding recess 16 is formed between the trim portion 11 and one side surface (vehicle inner side surface).
The interior of the vehicle interior such as the ceiling 54 is accommodated in the shielding recess 16 and shielded from the outside to improve the design effect in the vehicle.

The fin support 14 is provided with a fin 1
Since the fin 15 serves as a fulcrum F2 at the time of bending deformation in the thickness direction of the fin 5, the fin 15 is bent or inclined such that the top of the fin 15 is bent outward from the tip of the fin support 14 as shown in FIG. It is preferable to configure so as to be positioned at On the other hand, if the tip of the fin support portion 14 is located too far from the center of the fin portion 15 in the longitudinal direction, there is a possibility that a problem may occur in the followability at the time of bending at the corner of the door opening 53. Therefore, it is preferable to position the tip near the center in the longitudinal direction.

Further, continuously with the lower end of the fin portion 15,
Design part 1 made of the same soft resin material or rubber material
7 is integrally formed so as to cover the entire bottom surface and other side surface (vehicle outer side surface) of the trim portion 11. It is preferable that the holding lip 13, the fin 15 and the design 17 are formed of the same soft material from the viewpoint of moldability and the like. In particular, the fin 15 and the design 17 have the same design. It is preferable to use the same soft material.

As the relatively hard resin material or rubber material having a predetermined hardness for forming the trim portion 11 and the fin portion support portion 14, for example, polyvinyl chloride (PVC) or other synthetic resin materials may be used. it can. Also,
The hardness may be the same as the hardness of the hard material of the trim part 61 of the conventional example. However, in this embodiment, the trim part 11 and the fin support part 14 are externally covered by the fin part 15 and the design part 17. In view of the fact that it does not appear on the design surface, it is desirable to use a recycled material as a material for the trim portion 11 and the fin portion support portion 14.
It is preferable that the angle be in the range of 5 to 97 degrees. The hardness is appropriately changed depending on the material used.

On the other hand, as the soft resin material or rubber material forming the holding lip 13, the fin portion 15, and the design portion 17, for example, polyvinyl chloride (PVC) or other synthetic resin materials can be used. Although the hardness is slightly different depending on the material used, in the case of a synthetic resin material such as polyvinyl chloride (PVC), a JIS hardness of 7 is used.
It is preferable to select within the range of 0 to 80 degrees.
More preferably, the SA hardness is about 70 degrees. Further, in the case of a rubber material such as an olefin rubber, a JISA hardness of 6
It is preferable to select from a range of 0 to 75 degrees. When the hardness of the synthetic resin material is less than JISA 70 degrees, or when the hardness of the rubber material is less than 60 degrees, there is a possibility that a problem may occur in terms of moldability, and a sticky feeling may appear on the whole. This is not preferable, and may further increase the cost. Conversely, the hardness of the synthetic resin
If the value exceeds the degree, or if the hardness of the rubber material is 7
If the value exceeds 5 degrees, there is a possibility that a soft feeling cannot be sufficiently exerted.

The opening trim 10 of the present embodiment constructed as described above is manufactured by, for example, two-layer molding by injection molding, and the insertion recess 12 of the trim portion 11 is formed in the door opening 53 in the same manner as in the conventional example. It is possible to assemble the vehicle along the door opening 53 of the automobile by inserting it opposite to each other and elastically holding the outer surface of the door opening 53 by the two holding lips 13. At this time, the holding lip 13 made of a soft material securely holds the end of the door opening 53 in elastic contact.
Further, by inserting the end of the interior member of the vehicle into the shielding recess 16 inside the fin portion 15 and housing it, the end of the interior member is housed and shielded from the outside, and the design effect in the vehicle is improved. can do.

Here, the opening trim 1 of the present embodiment.
0, the fulcrum F2 of the fin 15 is located at the tip of the fin support 14, and the fulcrum F1 when the fin 15 is formed of the same hard material as the trim 11 as in the conventional example. As compared with the above, the vehicle is located closer to the inside of the vehicle by the distance D with respect to the tip top. In particular, in the present embodiment, the fulcrum F2 of the fin 15 is, as shown in FIG.
It is located much inside the car from the top. Therefore, when the opening trim 10 is bent and deformed in accordance with the curvature of the corner portion at the corner portion of the door opening portion 53, the fin portion 15 does not bend back to the vehicle interior due to stress applied to the vehicle interior. Rather, they tend to warp outward due to stress on the outside of the vehicle.

On the other hand, the opening trim 10 of this embodiment is
Has a fin portion 15 and a design portion 17 made of a soft material, and a trim portion 11 and a fin portion support portion 14 made of a hard material are covered with the design portion 17 and the fin portion 15 and are exposed to the outside. Never.

As described above, the opening trim 10 of the above embodiment has the insertion concave portion 12 which can be inserted at the end of the door opening 53 of the body 51 and has a substantially U-shaped cross section in which the insert 64 is embedded therein. A trim portion 11 made of a hard resin material or a rubber material having a predetermined hardness, and a predetermined portion which is integrally formed on a surface of the trim portion 11 facing the insertion concave portion 12 so as to elastically hold an end of the door opening 53. A holding lip 13 made of a soft resin material or a rubber material having a hardness, and a recess 12 for inserting the trim portion 11 on one side surface of the trim portion 11.
A fin support 14 integrally formed of a hard resin material or a rubber material having a predetermined hardness so as to extend in substantially the same direction as the opening direction of the fin, and covering the outer surface of the fin support 14 and the trim 11 The fin support portion 14 is formed integrally with the fin support portion 14 so as to extend in substantially the same direction as the opening direction of the insertion concave portion 12, and the trim portion 11 is formed together with the fin support portion 14.
A fin 15 made of a soft resin material or rubber material having a predetermined hardness to form a shielding recess 16 with the one side surface.
And a design part 17 formed of a predetermined soft resin material or rubber material, which is formed integrally and continuously with the lower end of the fin part 15 and covers the entire bottom surface and side surfaces of the trim part 11.

Therefore, in the above embodiment, the fin support portion 14 and the fin portion 15 covering the fin portion support portion 14 are integrally formed in the same direction as the opening direction of the insertion concave portion 12 of the trim portion 11. The shielding recess 16 extends between the
To form The fin support 14 made of a hard material does not easily bend and deform in the thickness direction with respect to external force, while the fin 15 made of a soft material is more easily deformed than the fin support 14 in the thickness direction. Is relatively easily bent.
Here, since the fin portion 15 is firmly supported on the base end side by the fin portion support portion 14 and the bending deformation is regulated, the fulcrum F2 of the fin portion 15 at the time of the curvature is set to the fin portion support portion. 14, the trim portion 61 and the fin portion 62 are more integrally formed with the tip of the fin portion 15 as compared to the conventional example in which the trim portion 61 and the fin portion 62 are integrally formed of a single hard material. They will be located close together. As a result, when the trim portion 11 is inserted and held in the door opening portion 53 of the body 51, the fin portion 15 can be effectively prevented from warping inward of the vehicle, and the fin portion 11 reliably blocks the end of the interior member. By doing so, it is possible to always ensure good design in the car. Further, as in the conventional example, in order to prevent the fin portion 62 from warping toward the inside of the vehicle at the corner portion of the door opening portion 53, the door opening portion 53 is provided before the opening trim 60 is attached to the door opening portion 53. Fin 6 corresponding to the corner
Since there is no need for habit work such as 2 etc., productivity is improved,
Manufacturing costs can be reduced.

Further, since the fin portion 15 and the design portion 17 constituting the design surface are made of a soft material, a soft feeling is given to the entire design surface. As a result, the opening trim 10
The appearance of the design can give a sense of luxury.

Further, the trim portion 11 and the fin support portion 14 are provided.
Is covered with the design portion 17 and the fin portion 15 and does not constitute a design surface, so that its appearance quality is not regarded as a problem. As a result, as a hard material for the trim portion 11 and the fin support portion 14, a recycled material, which is a second-class material, can be used, so that the manufacturing cost can be further reduced and the recycling which has been increasing more and more in recent years from the viewpoint of environmental protection. Can also respond to requests. In addition, the opening trim 1 of the present embodiment
0 is formed of two layers, and the holding lip 13 elastically contacting the door opening 53 is formed of a soft material, so that the hardness of the trim portion 11 and the fin supporting portion 14 which are hard materials requires a certain degree of flexibility. It can be determined regardless of the hardness of the holding lip 13. As a result, the hardness of the trim portion and the fin portion support portion is increased, and the door opening portion 53 through the holding lip 13 is increased.
Can be increased, and the mounting force of the opening trim 10 on the door opening 53 can be improved.

By the way, the fin support portion 14 of the above embodiment is used.
Extends from the side of the trim portion 11 (inside the vehicle) upward (in the opening direction of the insertion concave portion 12) and extends at an acute angle. Is not limited to this, and may be any as long as it extends in substantially the same direction as the opening direction of the insertion recess 12 of the trim portion 11. Also, in the above embodiment, the fin portion 15 is also configured so that the top of the tip is curved or inclined outward from the tip of the fin support portion 14. Any shape may be used as long as it extends in substantially the same direction as the opening direction and cooperates with the inner surface of the fin support portion 14 to form a shielding recess 16 between the trim portion 11 and one side surface (the vehicle inner side surface). For example, another configuration such as providing the fin portion 15 substantially vertically above the fin portion support portion 14 is also possible.

Further, in the above embodiment, the entire outer surfaces of the trim portion 11 and the fin support portion 14 made of a hard material are covered with the design portion 17 and the fin portion 15 made of a soft material. If only the fin 15 visually recognized by the above is formed of a soft material, a desired design effect can be expected. Therefore, the design 17 is provided only on the bottom surface of the trim 11 according to the design of the opening mall. The design part 17 may be abolished.

In the above embodiment, the holding lip 13
Is formed of the same soft material as the fin portion 15 and the design portion 17, but the holding lip 13 becomes the fin portion 15 and the design portion 17 as long as the end portion of the door opening 53 can be reliably elastically held. It may be formed of a soft material or a hard material.

Further, the shapes or configurations of the trim portion 61, the holding lip 13, and the fin portion 15 in the above embodiment are not limited to those in the above embodiment, and may be changed as appropriate, such as eliminating the insert 64. In addition, its material or manufacturing method can be appropriately selected.
