Description

  The present invention relates to a vehicle roof rail made of an extrusion-molded body such as a metal material (aluminum) and a method for manufacturing the same.

  Vehicle roof rails are mainly attached to wagon vehicles and off-road vehicles, and various types of roof rails have already been proposed. For example, in the case of a vehicle roof rail composed of two rail members attached to both outer edges of the vehicle roof in the front-rear direction, a long beam portion (usually a rod shape such as a square pipe shape) extending in the front-rear direction of the normal vehicle. Part) and both leg parts (attachment parts to the vehicle roof) attached to both ends.

In the vehicle roof rail having such a structure, when the beam portion and the leg portion are formed of separate members, it is necessary to connect both of them. For this reason, the structure of a connection part becomes complicated, manufacture is troublesome, and becomes the cause of a cost increase. In addition, if the beam part and the leg part are made of separate members, there are problems such as subtle steps between them and subtle differences in color (such as metal color). There was a concern that the merchandise value would be greatly lost.
On the other hand, in recent wagon cars and off-road vehicles, the roof rails for vehicles have a stronger factor than the original function, that is, the luggage loading function, and this tendency is increasing. For this reason, the appearance of the vehicle roof rail, that is, a beautiful finish, is extremely important and greatly affects the commercial value.

For this reason, even if it exists in the past, after forming a beam part and a leg part integrally in some roof rails for vehicles, it finishes in a desired shape by post-processing (patent documents 1), and a beam part (Patent Document 2) and the like have been proposed in which the beam portion is supported by an auxiliary leg (supporting member) after being integrally formed in a shape including the leg portion.
JP 2001-158304 A JP 07-315135 A

  However, in the case of Patent Document 1, a beautifully finished appearance with a sense of unity between the beam part and the leg part can be obtained, but shape forming of the leg part by post-processing (bulging shape, etc.) is very difficult. There were problems such as poor workability. There is also a problem that special processing equipment and tools are required for special shape molding. Therefore, it can be said that cost reduction is difficult. On the other hand, in the case of Patent Document 2, although the auxiliary leg portion is difficult to stand out with a small structural part, it is basically exposed to the outside as a separate part from the beam part. Problems such as subtle steps in the beam and auxiliary legs, and subtle differences in color were not solved, and there were limits to the beautiful appearance.

  Therefore, as a result of intensive studies, the inventors of the present invention have used a metal material such as aluminum to form a main body of a vehicle roof rail. When extruding a long beam portion, the bowl portion is integrally formed with the beam portion. When the extruded piece is also extruded, it is possible to give a good sense of unity between the beam part and the leg part by simple processing thereafter, and the extruded piece can be used as a cover part for blindfold or various As a result, it was found that a vehicle roof rail excellent in cost and appearance can be obtained and applied (Japanese Patent Application No. 2006-047979). .

  Then, in actual production, an extrusion-molded body in which a long beam portion and a leg portion at both ends thereof are formed in an approximately arcuate shape is integrally formed, and the bowl-shaped extruded piece integrally formed therewith is removed (cut). Then, when leaving the cover part, the following room for improvement was found.

For example, as shown in FIGS. 2C to 2D, when the cover-shaped 131 of the leg portion 120 is formed by removing (cutting) the hook-shaped extruded piece 130 of the extruded molded body 100, The removal of the extruded piece 130 needs to be performed in a clean form along the bottom surface side of the beam portion 110.
However, the extrusion molded body 100 may be slightly distorted or twisted in the longitudinal direction in dimension due to the characteristic of extrusion molding. When cutting with a press or a milling machine is performed under this situation, for example, as shown in FIGS. 22A to 22C, the extruded piece 130 is substantially horizontal (surface) with the bottom surface side 110 a of the beam portion 110. 1) [FIG. 22 (A)], but depending on the location (part), the cut portion of the extruded piece 130 may remain in a convex shape (FIG. 22 (B)) or in a concave shape on the bottom side 110a. There was a bite. In addition, even if the extruded piece 130 is in a portion that is cut flush with the bottom surface side 110a of the beam portion 110, when observed in detail, the cut portion of the extruded piece 130 extends so that the bottom surface side 110a of the beam portion 120 extends. There was a case where rubbing traces remained on the edge of the.

  Vehicle roof rails are extremely fashionable (design) -rich equipment that has an important appearance, so if the above situation occurs, the value of the product will be significantly reduced and defective products will be rejected. ).

  The present invention has been made from this point of view. Basically, a rod-shaped extruded piece is extruded together with a beam portion (including a leg portion), and simple post-processing is performed on the extruded portion. By applying this, it is possible to reduce the cost and to prevent a difference in level and color between the beam portion and the leg portion.

That is, rapid manufacturing is possible and a work improvement function is obtained.

FIG. 1 shows one embodiment of a vehicle roof rail according to the present invention.
The vehicle roof rail 100A has a generally arcuate shape as a whole, and covers a long beam portion 110 constituting the rail body, leg portions 120 at both ends thereof, and one side of the leg portion 120 (usually the outside of the roof). 131 and a leg fixing member 140 which is fixed to the bottom surface of the leg and to which a vehicle mounting means 151 such as a screw or a nut is mounted.

  In manufacturing the vehicle roof rail 100A, first, as shown in FIG. 2A, a metal material (such as a hard resin material) such as aluminum or an alloy thereof is extrusion-molded to obtain, for example, a substantially trapezoidal shape. The long extrudate 100 is obtained. At this time, together with the long beam portion 110, the hook-shaped extruded piece 130 is integrally formed along the longitudinal direction of the beam portion 110. In addition, although the shape of the beam part 110 is usually a rectangular pipe-shaped cylindrical structure, it may be a round pipe-shaped cylindrical structure or a frame structure. Further, the extruded piece 130 can be provided not only on the outside of the roof but also on the inside of the roof. Furthermore, in addition to these, it is also possible to add at appropriate places. The widths of these extruded pieces can be adjusted as appropriate.

  After that, as shown in FIG. 2B, the beam section 110 is cut into a predetermined length (a length corresponding to at least one rail), and both ends of the beam section 110 are bent and formed in the same direction in a leg shape. 120. At this time, if necessary, the beam part 110 can also be bent in a form that is slightly aligned with the leg part 120 and slightly inflates upward. As a result, a generally arcuate shape with a beautiful shape is obtained as a whole. Of course, the bending width of the leg portion 120 and the beam portion 110 can be adjusted as appropriate.

  Next, as shown in FIG. 2C, the bottom surface 120a of the leg 120 is cut substantially horizontally, for example, in correspondence with the mounting surface (roof surface) of the vehicle roof. Depending on the cutting location, the extrusion-molded body 100 having a predetermined length cut in the previous step of FIG. 2B may be slightly shortened. Thereafter, as shown in FIG. 2D, the eaves-like extruded piece 130 is removed leaving only the vicinity of the outside of the roof of the leg portion 120 (when the roof rail is attached as the outer side of the extruded piece 130). Thereby, the cover part 131 which consists of a small arc-shaped (crescent shape) small piece is obtained. As a result, as shown in FIG. 3, the extruded piece 130 in the beam portion 110 portion is almost eliminated, and the extruded piece 130 in the leg portion 120 portion remains as a cover portion 131 as shown in FIG. 4. Since the bottom surface 131a of the cover part 131 is cut in accordance with the mounting surface of the vehicle roof, the cover 131 is in close contact with the vehicle roof at the time of mounting.

  The vehicle roof rail 100A shown in FIG. 1 is obtained by fixing the leg fixing member 140 to the bottom surface side of the leg portion 120 of the extrusion molded body thus obtained. The fixing structure of the leg fixing member 140 has a symmetrical structure on the left and right of the leg portion 120, and is enlarged as shown in FIGS.

  The leg fixing member 140 is made of a metal block or a hard resin block, and has a structure that is fitted into an empty space portion (cut opening) on the bottom surface side of the leg portion 120. As is apparent from FIG. 5, the leg fixing member 140 is attached to the vehicle with two (one or two or more screws) screws (screw equivalent members are also necessary) that are required for attachment to the vehicle roof. Means 151 are mounted. The vehicle attachment means 151 can be a nut (a member corresponding to a nut is also acceptable). In that case, a screw or a screw-equivalent member may be used as the vehicle-mounted attachment means. Furthermore, a nut structure of a female screw may be formed directly on the thick part on the leg fixing member 140 side.

  The fixing of the leg fixing member 140 to the leg 120 side is not particularly limited, but in the illustrated case, it is performed by a fixing tool 160 including a caulking nut 161 and a screw 162. Specifically, if the mounting hole 121 is made in the bottom surface side of the leg portion 120 (the bottom surface side frame portion of the extruded molded body), the caulking nut 161 and the screw 162 are fitted into this, and the screw 162 is tightened, the caulking nut 161 is crushed. It can be easily and firmly fixed to the mounting hole 121.

  Then, the screw of the vehicle mounting means 151 that is mounted in advance on the leg fixing member 140 is fitted into the mounting hole (not shown) of the vehicle roof from the outside, and a nut or a nut equivalent member (not shown) is mounted from the inside of the vehicle. Thus, the target vehicle roof rail 100A can be attached. In this mounted state, the bottom surface of the leg fixing member 140 and the bottom surface 131a side of the cover portion 131 are in close contact with the vehicle roof, so that a stable and strong mounting state can be obtained. In particular, the bottom 131a side of the cover portion 131 is in close contact with the vehicle roof over a long range, which can greatly contribute to the stability of the mounted state. That is, a reinforcing effect can be obtained. Further, since the bottom 131a side of the cover 131 is located outside the roof and is in close contact with the vehicle roof, a blinding effect on the leg fixing member 140 can be obtained. Further, as apparent from FIG. 7 (view from the bottom surface side), the cover 131 has a shape that slightly bulges outward, so that an effect of improving visual stability with respect to the leg 120 can also be obtained. Of course, as described above, there is no connection part between the beam part 110 and the leg part 120, and a complete and clean sense of unity can be obtained. In other words, a beautiful finish is obtained.

  In the above case, it is necessary to handle the attachment of the vehicle roof rail 100A from the inside of the vehicle. There is no particular problem at the production line stage in the vehicle factory, but there is a restriction that it cannot be handled after the interior processing of the vehicle ceiling is completed as a process procedure (order). In addition, there is a concern that there may be a restriction that it is impossible to deal with a case where a work space such as a work tool cannot be secured due to the relationship with other members on the vehicle ceiling side.

  Therefore, in the present invention, as another aspect, as shown in FIGS. 8 to 11, the upper surface side of the leg portion 120 (the upper surface side frame portion of the extrusion-molded body) so that the operation from the outside of the vehicle is possible. Are provided with a working opening 122 and a lid piece (cap) 170 thereof.

In this aspect, the fixing member 160 including at least one (one set) caulking nut 161 and a screw 162 is used to attach the leg fixing member 140 to the mounting hole on the bottom surface side of the leg portion 120 (bottom surface side frame portion of the extruded molded body). 121, and screw 162 is tightened and fixed.
In the other fixture 160a and the vehicle attachment means 151, the lid piece 170 is removed and the operation is performed from the opening 122. In addition, about the screw of the other fixing tool 160a, it fixes to the nut structure part of the internal thread previously formed in the leg fixing member 140 side, or it fixes to a nut (illustration omitted). Further, the fixture 160 a can also be composed of a caulking nut 161 and a screw 162.

  The lid piece 170 is attached and detached on the inside of the upper surface side of the leg portion 120 (the frame portion on the upper surface side of the extruded body), for example, two parallel rail pieces 123 for engagement such as a substantially L-shape, and these just The lid receiving member 171 attached to the four corners of the opening 122 and the detachable panel piece 172 provided on the back side of the lid piece 170 are easily and quickly performed.

  The parallel rail pieces 123 can be simultaneously molded at the time of extrusion molding of the extruded product. The lid receiving member 171 is provided with a fitting groove 171a fitted to the parallel rail piece 123, and is fitted to the parallel rail piece 123 by a sliding method. At a predetermined position, it may be stopped with a double-sided adhesive tape or the like. When the lid 170 is fitted into the opening 122, the space between the left and right hook-shaped elastic movable parts 172a and 172a is reduced by press-fitting and passes through the opening 122. The lid piece 170 is held by restoring and contacting the inner edge of the opening 122. When removing the lid piece 170, a thin knife-like tool may be inserted into the gap with the opening 122 and removed by overcoming the drag of the detachable panel piece 172 using the lever action of the tool.

  In securing the leg fixing member 140, as shown in FIGS. 12 and 13, in order to ensure better fixing stability, the leg fixing member 140 side and the bottom side of the leg part side (the bottom surface of the extruded product) Protrusions 141 (including protrusions having an engagement function) and fitting holes 124 (grooves having an engagement function), etc., which are fitted to each other on both sides of the side frame portion) which are in contact with each other Are also included). The number of protrusions 141 is not limited to two, and may be two or more or one. Contrary to the illustration, the side on which the projection (projection-shaped one) and the fitting hole (such as a groove) are provided can be reversed.

FIG. 14 shows another aspect of the vehicle roof rail according to the present invention.
The vehicle roof rail 100B is basically the same as the vehicle roof rail 100A, but has a structure in which the cover portion 132 is lengthened to cover the entire length of the beam portion 110 and both leg portions 120 outside the roof. In this case, the bottom surface 132a side of the cover portion 132 is extremely long and is in close contact with the vehicle roof over the entire length of the roof rail, so that a very large reinforcing effect is obtained. Further, since the roof rail is in close contact with the entire length of the roof rail, an extremely good sense of unity with the vehicle roof can be obtained. The mounting structure to the vehicle roof is exactly the same as that of the vehicle roof rail 100A, and can be made from inside and outside the vehicle.

  The method of manufacturing the vehicle roof rail 100B is basically the same as that of the vehicle roof rail 100A. However, as shown in FIG. 15, the hook-shaped extruded piece 130 integrally formed with the extruded body 100 is formed. The width may be increased so that the entire length of the extruded piece 130 remains when the legs 120 are cut.

In addition to leaving the hook-shaped extruded piece 130 over the entire length as described above, for example, as shown in the vehicle roof rails 100C to 100F shown in FIGS. It can also be set as the cover parts 133-136 which cover the suitable location of the roof outer side.
In FIG. 16, the above-described leg fixing member 140 is provided inside the central portion of the beam portion 110, and this portion is covered with the cover portion 133. This is effective when the length of the roof rail is long, or when the mounting strength is enhanced to obtain a larger load carrying function. In the case of FIGS. 17 to 19, the cover part 134 itself has a design shape, or another design shape is applied to the cover parts 135 to 136. Thereby, an unprecedented design structure can be obtained relatively easily. Since this is complicated in shape, it can be handled as a special order vehicle or a special order product for retrofitting. Of course, if these cover parts are also in close contact with the vehicle roof side, a good reinforcing effect can be obtained. Moreover, when the length of the extruded piece 130 is appropriately formed as described above and partially formed, the opened portion (opening) can be used as a rope hooking hole or the like.

  In the above description, the vehicle roof rail is attached in the front-rear direction of the vehicle. However, the present invention is of course not limited to this and can be applied to a vehicle roof rail attached in the vehicle width direction. Further, the attaching / detaching and holding means of the lid piece in the corresponding vehicle roof rail from the outside of the vehicle having the working opening and the lid piece are not limited to those described above.

FIG. 20 shows another aspect of the vehicle roof rail according to the present invention.
In the case of this vehicle roof rail 100F, the overall structure is substantially the same as that of the vehicle roof rails 100A to E described above, but the inside of the base end portion 130a of the hook-shaped extruded piece 130 and the beam portion 110. A recessed portion (concave groove) 110c is formed by extrusion molding in the longitudinal direction between the bottom surface side 110a and the edge portion 110b.

  The shape of the recessed portion 110c is not particularly limited, and when the base end portion 130a side of the extruded piece 130 is cut, an appropriate space (space) S between the cut portion and the bottom surface side 110a side of the beam portion 110. Any shape can be used. Usually, the distance S should be about 4 to 6 mm, although it depends on the type of roof rail.

  When such an interval S is formed, when the eaves-like extruded piece 130 is cut at the time of manufacturing the roof rail, for example, as shown in FIG. 21, the reference surface (the surface substantially the same as the bottom surface side 110 a side of the beam portion 110). Even if the cut surface L1 protrudes slightly convex with respect to the horizontal reference dimension surface L0, or the cut surface L2 bites slightly concave, these irregularities are If it is within ± 2.0 mm with respect to the dimension value, it may be difficult for an observer (vehicle dealer, user, etc.) to visually recognize it as a step or the like. That is, some steps and the like are within an allowable range. In other words, even if there are some level differences, the product can be handled as a non-defective product, and a function for expanding the non-defective product tolerance can be obtained.

  In addition, from the viewpoint of manufacturing work, such a point can be worked without much concern for convex steps, dents, and rubbing. That is, it is possible to obtain a work improvement function that enables rapid manufacturing and improves workability.
