Description

The present invention relates to a long body attached to a vehicle and having at least a rigid wall having a certain rigidity, and a method for manufacturing the same.

Such a long body includes an outer belt molding and an inner belt molding arranged along the window glass elevating opening of the vehicle door, and a roof attached to a roof groove which is a joint between the roof panel and the roof side panel. There are moldings and seat rail covers that are mounted so as to cover the seat rails that slidably support the legs erected under the vehicle seats. These long bodies consist of a lip portion that holds the attached state by bullet contact (pressure contact in an elastically deformed state) with the mating member to be attached, and a main body portion that serves as a base material (base) of the lip portion. .. The lip portion is made of a flexible material having a high elastic deformability. On the other hand, the main body portion has a certain rigidity (shape retention) in order to define the basic shape of the long body and secure the holding force by the lip portion.

For example, the main body of the outer belt molding and the inner belt molding is substantially U-shaped by two side walls that are erected facing each other and a connecting wall that connects both side walls (also called a top wall or a bottom wall depending on the mounting direction). The body panel, which is the mating member, and the peripheral edge of the vehicle component are inserted into the main body. The main body of the roof molding has a substantially T-shape including a support column standing in the roof groove and an upper surface wall covering the upper surface opening of the roof groove. The main body of the seat rail cover has a substantially T-shape or a substantially L-shape including a support column erected in the seat rail and an upper surface wall covering the upper opening of the seat rail. As described above, the long body attached to the vehicle has at least a rigid wall having a certain rigidity. That is, the main body of the outer belt molding and the inner belt molding, and the columns and the upper surface wall of the roof molding and the seat rail cover correspond to the rigid walls, respectively. Further, the rigid wall has an outer surface exposed to the outside and an inner surface not exposed to the outside, and typically, the outer surface exposed to the outside forms the appearance of a long body.

When these long bodies are attached to a vehicle, the longitudinal end face of the long body faces the other in order to reduce the distance between the longitudinal end of the long body and the mating member to make the gap as small as possible. Depending on the shape of the member, it may be an inclined surface. In particular, if the long body is an outer belt molding, at least the tip surface of the outer belt molding is often an inclined surface along the inclination of the door panel facing the outer belt molding. Specifically, the tip surface of the outer side wall of the outer belt molding is inclined toward the other end side from the outer surface side to the inner surface side. In this case, the corner portion between the outer surface of the outer side wall of the vehicle and the inclined surface (tip surface) is an acute angle.

In this case, if a finger is caught on the tip corner of the outer belt molding when transporting or attaching to the vehicle body panel, the pressure is high and the feeling of attack from the outer belt molding is strong, which is unpleasant. Gripping hard or sliding your fingers sideways can cause pain and injury. Such discomfort and danger are not limited to the outer belt molding but other long lengths as long as the longitudinal end surface (front end surface or rear end surface) of the rigid wall having a certain rigidity is an inclined surface. The same is true for the body.

Further, when the rigid wall is exposed to the outside, the outer surface of the rigid wall may be covered with a decorative coating in order to enhance the design. Even if the decorative coating is provided as described above, the corners between the outer surface and the inclined surface of the rigid wall including the decorative coating are still sharp, and there is still the above-mentioned discomfort and danger.

Here, Patent Document 1 below is disclosed as a method for processing the end portion in the longitudinal direction of a long body. Also in the long body described in Patent Document 1, the outer surface (design surface) of the outer side wall of the vehicle, which is a rigid wall, is covered with a decorative coating. In addition, Patent Document 1 improves the appearance of the design surface by preventing the occurrence of boundary lines, burrs, steps, etc. at the end in the longitudinal direction in the manufacturing process of the elongated body, and improves the appearance of the design surface in the longitudinal direction of the elongated body. The end is heat-deformed by die press molding for finishing.

Japanese Unexamined Patent Publication No. 8-267609

Also in the long body described in Patent Document 1, the end surface in the longitudinal direction is an inclined surface, and the corner portion between the outer surface (design surface) of the outer side wall of the vehicle and the inclined surface is covered with a decorative coating. However, the inclined surface here is inclined toward the other end side from the inner surface side to the outer surface side, and the corner portion between the outer surface and the inclined surface of the outer side wall of the vehicle is an obtuse angle. On the other hand, the corner between the inner surface of the outer side wall of the vehicle and the inclined surface is an acute angle. The corner between the inner surface and the inclined surface of the outer side wall of the vehicle is also covered with the decorative coating, but the angle is acute including the decorative coating. With this, it is undeniable that there is discomfort when a finger is hung on the end face in the longitudinal direction of the long body and there is a danger when the finger is firmly gripped.

Further, in Patent Document 1, the end portion in the longitudinal direction of the long body is thermally deformed by die press molding. In this case, not only a mold is required and the device becomes large-scale, but also the final shape is formed by thermal deformation. Therefore, it is difficult to reliably form the desired final shape unless the conditions are set strictly. ..

Therefore, the present invention solves the above-mentioned problems, and is a long body having less discomfort and danger when a finger is caught on the end in the longitudinal direction, and a method for manufacturing the long body which can be easily manufactured. The purpose is to provide.

As a means for that purpose, the elongated body of the present invention is attached to a vehicle and has at least a rigid wall having a certain rigidity, and the rigid wall includes an outer surface exposed to the outside and an inner surface not exposed to the outside. At least one end surface in the longitudinal direction of the rigid wall is an inclined surface inclined toward the other end side from the outer surface side to the inner surface side. On top of that, the corners of the outer surface of the rigid wall and the inclined surface are rounded in an arc shape.

In the long body of the present invention, at least one end surface in the longitudinal direction of a rigid wall having a certain rigidity is an inclined surface inclined from the outer surface side to the inner surface side toward the other end surface. Therefore, when attached to the vehicle, the gap between one end thereof and the mating member facing the end thereof is reduced, and the appearance and the function of the long body are improved. On top of that, the acute-angled corners between the outer surface and the inclined surface of the rigid wall have an arc shape. According to this, even if the operator's finger hangs on one end of the rigid wall during transportation or installation work on the vehicle, the pressure received from the long body is reduced, causing discomfort and injury. The risk of injury can be reduced.

Since the corners of the inner surface and the inclined surface of the rigid wall are obtuse angles, it does not necessarily have to be arcuate.

When the outer surface of the rigid wall is exposed and visible from the outside, it is preferable to cover the outer surface of the rigid wall with a decorative coating. As a result, the appearance is improved and the design is improved. At this time, it is preferable that the corners between the outer surface of the rigid wall and the inclined surface are also covered with the decorative coating. As a result, the appearance of the outer wall surface as seen from the end side is also improved. In this case, it is preferable to form the decorative coating in the rounded arc shape. This is because even if the corners of the rigid wall body have an arc shape, if the decorative coating covering the rigid wall body has an acute angle, there is a high risk of discomfort or injury.

On the other hand, it is preferable that the inner surface of the rigid wall is not covered with the decorative coating, and the decorative coating does not reach the corners between the inner surface of the rigid wall and the inclined surface. The decorative coating only improves the appearance from the outside, but since the end face of the rigid wall is an inclined surface that is inclined from the outer surface to the inner surface, the part on the inner surface side of the inclined surface and the inner surface side of the rigid wall Is almost never visible. For this reason, it is wasteful of material cost and labor to cover the inner surface side of the rigid wall and the corner portion between the inner surface of the rigid wall and the inclined surface with the decorative coating film.

The decorative coating is preferably formed of a material that is more deformable than the rigid wall. According to this, it becomes easy to form the decorative film into an arc shape along the corners of the rigid wall in the manufacturing process.

When one end of the rigid wall in the longitudinal direction has a tapered shape toward the center in the height direction, the outer surface and the inclined surface of the rigid wall also have a tapered top of the one end of the rigid wall. It is preferable that the corners of the sword have a rounded arc shape. As a result, the corners of the tapered top, which can receive the greatest pressure from the long body, are also neatly arcuate, effectively reducing discomfort and danger even if a finger hangs on the part. can do.

Further, according to the present invention, the rigid wall is attached to a vehicle and has at least a rigid wall having a certain rigidity, and the rigid wall includes an outer surface exposed to the outside and an inner surface not exposed to the outside, and the rigid wall is provided in the longitudinal direction of the rigid wall. It is also possible to provide a method for manufacturing a long body in which at least one end surface thereof is an inclined surface inclined toward the other end side from the outer surface side to the inner surface side. In this manufacturing method, a cutting step of cutting an extruded member extruded by extrusion molding as an intermediate having a rough length and a rough end shape, and molding the longitudinal end of the intermediate body into a final length and a final shape. It has a finishing process to be performed. Then, the finishing step is a step of cutting the longitudinal end portion of the intermediate body, and the corner portion between the outer surface of the rigid wall and the inclined surface is rounded due to the cutting of the longitudinal end portion of the intermediate body. It is characterized by having an arc shape with a tinge.

According to this, the shape of the end portion in the longitudinal direction of the long body is formed by cutting, and the corner portion between the outer surface and the inclined surface of the rigid wall becomes an arc shape due to cutting, so that it is a strict condition for processing. No setting is required, and it can be manufactured easily and easily.

The cutting in the finishing step is preferably performed by press cutting. According to this, the shape of the end portion in the longitudinal direction can be processed more easily and easily.

In this case, in the finishing step, it is preferable that the intermediate is arranged diagonally and cut in the vertical direction. As a result, the shape of the end portion in the longitudinal direction can be accurately processed.

When the outer surface of the rigid wall is covered with a decorative coating, a coating step of covering the outer surface of the rigid wall with a decorative coating is provided before the finishing step. Then, in the finishing step, the decorative coating film may also be cut. As a result, it is possible to form an arc shape including the decorative coating by cutting.

The decorative coating is preferably formed of a material that is more deformable than the rigid wall. This facilitates the formation of the decorative coating in an arc shape along the corners of the rigid wall. Further, since the shear stress generated at the time of cutting is small, it is possible to prevent the decorative coating film from hindering the cutting.

When one end of the rigid wall in the longitudinal direction has a tapered shape toward the central portion in the height direction, it is preferable that the cutting blade in the finishing process has a curved shape corresponding to the tapered shape. .. As a result, even a special shape can be accurately machined in one process with one cutting blade.

A typical example of the long body is an outer belt molding which is arranged along the upper edge of the outer door panel of the vehicle door and has an outer side wall of the vehicle, an inner side wall of the vehicle, and a top wall connecting both side walls. can. In this case, at least the outer side wall of the vehicle corresponds to the rigid wall of the present invention.

According to the long body of the present invention, even if a finger is caught on the longitudinal end portion when transporting or attaching to a vehicle, the corner portion of the longitudinal end portion has an arc shape, so that the receiving portion is received. The pressure decreases. As a result, it is possible to obtain a long body with less risk of discomfort or injury to the operator.

Further, according to the method for manufacturing a long body of the present invention, stricter condition setting is not required as compared with the case of processing by thermal deformation by a mold press, and the long body can be manufactured easily.

It is a perspective view of a vehicle door. FIG. 2 is a cross-sectional view taken along the line II-II of FIG. It is a side view of the outside of the outer belt molding. FIG. 3 is a sectional view taken along line IV-IV of FIG. It is a side view which shows the state of cutting in a finishing process. It is sectional drawing corresponding to line IV-IV of FIG. 3 in another embodiment.

The long body of the present invention is attached to a vehicle such as an automobile and has at least a rigid wall having a certain rigidity (shape retention), and the rigid wall includes an outer surface exposed to the outside and an inner surface not exposed to the outside. As long as at least one end surface of the rigid wall in the longitudinal direction has an inclined surface inclined from the outer surface side to the inner surface side toward the other end surface, it can be widely applied. For example, the outer belt molding and inner belt molding arranged along the window glass elevating opening of the vehicle door, the roof molding attached to the roof groove which is the joint between the roof panel and the roof side panel, and the lower part of the vehicle seat. Examples thereof include a seat rail cover that is mounted so as to cover a seat rail that slidably supports the legs erected on the floor.

These long bodies are manufactured through extrusion molding, and integrally have a main body portion having a certain rigidity (shape retention) and one or a plurality of lip portions extending in each direction from an appropriate position of the main body portion. Have. The lip portion is highly elastically deformable, and the attached state is maintained by making a bullet contact with the mating member to be attached. The rigidity in the present invention does not necessarily mean a high level of rigidity, but means a level having a shape retention property that is not easily deformed by the elasticity when the lip portion comes into contact with the mating member. ..

Hereinafter, as a typical embodiment of the present invention, an outer belt molding will be described as an example. As shown in FIG. 1, the outer belt molding 10 is attached along the upper edge of the outer door panel 2 of the vehicle door 1. As shown in FIG. 2, the outer belt molding 10 includes a vehicle outer side wall 11 and a vehicle inner side wall 12 which are erected at predetermined intervals, and a top wall (corresponding to a connecting wall) 13 which connects both side walls 11 and 12. It is provided with a main body portion configured in a substantially U shape. Reference numeral 15 is a seal lip that comes into contact with the window glass 3. Reference numeral 16 is a decorative lip that improves the appearance from the outside. Reference numeral 17 is a holding lip that comes into contact with the outer door panel 2.

The vehicle outer side wall 11, the vehicle inner side wall 12, and the top wall 13 constituting the main body are made of a thermoplastic resin having a certain rigidity (shape retention). Further, the vehicle outer side wall 11 has a central portion in the height direction curved or bent toward the outside (vehicle outer side), and has higher shape retention than the other walls 12 and 13. On the other hand, each of the lips 15, 16 and 17 is made of a material highly elastically deformable, for example, made of rubber or elastomer. These lips 15, 16 and 17 correspond to the lip portion. Further, as will be described in detail later, in the present embodiment, the vehicle outer side wall 11 corresponds to the rigid wall of the present invention.

The outer door panel 2 is made of metal, and its upper edge is bent into a flange shape. Then, the upper edge flange portion 2a is inserted between the vehicle outer side wall 11 and the vehicle inner side wall 12. In this state, each holding lip 17 comes into contact with the upper edge flange portion 2a, so that the outer belt molding 10 is held in a state of being attached to the outer door panel 2.

When the outer belt molding 10 is attached to the outer door panel 2, the vehicle outer side wall 11 is located outside the vehicle from the upper edge flange portion 2a of the outer door panel 2 and is exposed to the outside. In this sense, the vehicle outer side wall 11 can also be referred to as an outer wall. Therefore, in order to improve the appearance (design) from the outside, the outer surface of the vehicle outer side wall 11 is covered with the decorative coating 14. The decorative coating 14 is made of a material that is more deformable (easily stretchable) than the main body including the outer side wall 11 of the vehicle. Specifically, in addition to thermoplastic resins and elastomers that are easier to stretch than the thermoplastic resin that forms the main body including the outer side wall 11 of the vehicle, even if it is a single-layer or multi-layer resin film or a film having a metal layer. good. Further, the decorative coating 14 may be a material having the same or harder hardness as the thermoplastic resin forming the main body portion, and may be a material having higher scratch resistance than the thermoplastic resin forming the main body portion.

The inner surface of the outer side wall 11 of the vehicle is not covered with the decorative coating 14, and the main body is exposed. By arranging the decorative coating 14 only in the necessary parts, waste of the material can be eliminated, and further, when the decorative coating 14 is made of a material harder than the main body, the contact between the attached body and the decorative coating causes the decorative coating 14 to be placed. It is possible to prevent abnormal noise and damage to the surface of the attached body.

The outer belt molding 10 is formed to have substantially the same shape over the entire longitudinal direction, but as shown in FIG. 3, the inner side wall 12 of the vehicle is missing over a predetermined range at the tip portion (one end portion in the longitudinal direction). is doing. The range in which the vehicle inner side wall 12 is missing depends on the shape and arrangement of the outer door panel 2 and other components of the vehicle door 1. Further, the tip portion of the outer belt molding 10 has a tapered shape toward the central portion in the height direction (vertical direction) in order to minimize the gap between the outer belt molding 10 and the mating member and improve the design. It has a slightly pointed shape.

Further, as shown in FIG. 4, the tip surface 11a of the vehicle outer side wall 11 is inclined toward the rear side (the other end side in the longitudinal direction) from the outer surface side to the inner surface side along the shape of the outer door panel 2 facing the outer side wall 11. It is a face. As a result, the gap W between the outer belt molding 10 and the outer door panel 2 which is the mating member becomes smaller. On the other hand, the rear end (the other end in the longitudinal direction) of the outer belt molding 10 is a straight flat surface as shown in FIG. If necessary, an end cap may be attached to the rear end of the outer belt molding 10.

The decorative coating 14 reaches the corner portion (hereinafter, referred to as the outer corner portion 11b) between the outer surface of the outer side wall 11 of the vehicle and the inclined surface 11a, and also covers the outer corner portion 11b. The outer corner portion 11b has an acute angle, but has a rounded arc shape. On top of that, the decorative coating 14 that covers the outer corner portion 11b also has an arc shape that follows the arc shape of the outer corner portion 11b. As a result, even if a worker's finger hangs on the tip of the outer belt molding 10 when transporting the outer belt molding 10 or attaching it to a vehicle, the acute outer corner portion 11b including the decorative coating 14 has an arc shape. Therefore, the risk of discomfort or injury is low. The tip of the outer belt molding 10 has a tapered shape, but as is often shown in FIG. 4, even at the top of this tapered shape, the decorative coating 14 including the outer corner portion 11b has a rounded arc. It has a shape. Therefore, even if the operator's finger hangs on the top of the sharpest tapered shape, the discomfort and danger are effectively reduced.

On the other hand, the corner portion between the inner surface of the vehicle outer side wall 11 and the inclined surface 11a (hereinafter referred to as the inner corner portion 11c) is not covered with the decorative coating 14. Since the inner corner portion 11c is located on the rear side of the outer corner portion 11b, the operator's finger is rarely caught. Even if the operator's finger touches the inner angle portion 11c, since the inner angle portion 11 has an obtuse angle, the discomfort and danger of the outer corner portion 11b are inherently low. Therefore, the internal angle portion 11c does not need to have an arc shape.

Such an outer belt molding 10 is manufactured through well-known extrusion molding. Specifically, an extrusion step of extruding a material softened by heating into a series of predetermined shapes, and a cutting step of cutting an extruded member extruded by extrusion molding as an intermediate body having a coarse length and a rough end shape. , Manufactured through a finishing step of molding the longitudinal end of the intermediate into the final length and final shape. Further, in the outer belt molding 10 of the present embodiment, since the outer surface of the vehicle outer side wall 11 is covered with the decorative coating 14, the outer surface of the vehicle outer side wall 11 is also covered with the decorative coating 14.

In the extrusion process, the material for the lips 15, 16 and 17 and the material for the vehicle outer side wall 11, the vehicle inner side wall 12, and the top wall 13 constituting the main body are extruded at the same time, so that these are integrally molded. Will be done. When the decorative coating 14 is used as a thermoplastic material, molding and coating can be performed at the same time by extruding the decorative coating 14 at the same time as other materials in the extrusion process. In this case, the extrusion process and the coating process are performed at the same time. On the other hand, when a film or sheet is used as the decorative coating 14, the coating step can be performed at the same time as the extrusion step, and the decoration is performed as the coating step between the extrusion step and the cutting step or between the cutting step and the finishing step. The coating film 14 can also be attached or fused.

The cutting step is usually performed by press cutting, and an intermediate having a flat tip and trailing end is obtained. At this point, the processing of the rear end portion is completed. On the other hand, at the time of the intermediate obtained by the cutting step, the length and the shape of the tip portion are not the final length and shape. Therefore, a finishing process is performed to finish this intermediate as a final product.

In the finishing step, after cutting the car inner side wall 12 from the tip of the intermediate body, the tip of the car outer side wall 11 is cut into the final shape. The cutting here is also performed by press cutting, as shown in FIG. As the cutting blade (cutting blade) 20 used here, a curved cutting blade is used so that the tip end portion of the vehicle outer side wall 11 has a tapered shape. This eliminates the need for additional processing such as cutting into a tapered shape after cutting.

When cutting the tip of the intermediate in the finishing step, as shown in FIG. 5, a die 21 whose mounting surface is inclined with respect to the horizontal direction is used. Then, the intermediate body 10'is placed on the die 21 with the outer surface side facing up, and the intermediate body 10'is inclined with respect to the moving direction of the cutting blade 20 so that the tip end side is upward in the vertical direction. The cutting blade 20 is lowered vertically. As a result, the tip surface of the vehicle outer side wall 11 inevitably becomes an inclined surface. At this time, the outer corner portion 11b including the decorative coating 14 is stretched downward due to shear friction caused by the press cut, so that the outer corner portion 11b and the decorative coating 14 covering this portion both have a rounded arc shape. It becomes. That is, by press-cutting the cutting in the finishing step in the vertical direction with the intermediate body tilted, the outer corner portion 11b including the decorative coating 14 is formed into an arc shape at the same time as the inclined surface 11a is formed.

In the finishing step, it is preferable to keep at least the tip of the intermediate 10'heated or heated. As a result, the deformability of the vehicle outer side wall 11 and the decorative coating 14 is increased, and it becomes easy to form an arc shape.

Although the typical embodiments of the present invention have been described above, the present invention is not limited to this, and various modifications can be made without departing from the gist of the present invention. For example, as shown in FIG. 6, the outer surface of the vehicle outer side wall 11 does not necessarily have to be covered with the decorative coating 14. In this case, the coating step is not required in the manufacturing process. Even so, the outer corner portion 11b still has a rounded arc shape. The tip of the vehicle outer side wall 11 does not necessarily have to have a tapered shape.

The long body is a long body for vehicles other than the outer belt molding as long as it has at least a rigid wall having a certain rigidity and at least one end surface in the longitudinal direction of the rigid wall is an inclined surface. It is also applicable to. The outer corner portion may have an arc shape at the rear end portion instead of the front end portion. Further, not only one end portion in the longitudinal direction but also the outer corner portions of both end portions may have an arc shape.

The rigid wall may be not only the outer side wall of the vehicle but also other walls as long as it is a wall constituting the main body having a certain rigidity.

For cutting in the finishing process, the rigid wall can be cut diagonally by placing the intermediate horizontally and then moving the cutting blade non-vertically.
