Description

  The present invention relates to an opening trim that is assembled to a flange formed along a vehicle body opening edge of an automobile and elastically contacts a door panel.

This will be described with reference to FIGS. 1, 3, 8 and 9. The opening trim 20 assembled to the flange 2 formed along the vehicle body opening edge of the automobile has a substantially U-shaped cross section composed of a vehicle inner side wall portion 12, a vehicle outer side wall portion 13, and a back wall portion 14 connecting both side wall portions. The mounting base 10 is provided, and the flange 2 is clamped and assembled by a holding lip 21 protruding from the side wall. The opening trim 20 having such a shape is disclosed in, for example, Patent Document 1 and Patent Document 2.
JP 2006-232144 A Japanese Patent Laid-Open No. 8-142673

  Such an opening trim 20 is assembled with an opening having a substantially U-shaped cross section as an outer peripheral side. Accordingly, in the corner portion C of the vehicle body opening edge assembled in the bent state, a force is applied to the holding lip 21 to restore the elongation caused by the bending to the original state. This causes a so-called sink E that falls in the direction of 12 and forms a gap G with the flange 2 (see FIGS. 3, 7, and 8). The force acting on the lip 21 to restore the elongation to the original state is stronger at the lip root located on the outer peripheral side of the bending than at the lip tip.

  Therefore, the assembly force of the opening trim 20 with respect to the flange 2 is reduced, and in the worst case, there is a problem that the flange 2 is detached from the flange 2. This problem is conspicuous in two rear corner portions C1 located on the rear side of the rear door where the flange 2 is thin.

  In order to solve such a problem, a means for increasing the assembling force has been devised so far only in the corner portion C by reducing the distance between the inner wall portion and the outer wall portion of the opening trim by post-processing. .

  There is also a means for setting the entire circumference of the opening trim slightly longer than the length required for assembling the opening trim to the vehicle body opening edge and pressing the opening trim against the vehicle opening edge.

  In Patent Documents 1 and 2, no means for solving such a problem is shown.

  However, only in the above-described corner portion C, means for increasing the assembling force by narrowing the distance between the inner side wall portion and the outer side wall portion of the opening trim by post-processing is difficult to perform accurately. There is a problem in that productivity increases and productivity decreases.

  Also, the means that the entire length of the opening trim is set slightly longer than the length required to assemble the opening trim and the opening trim is pressed against the opening edge of the opening trim can alleviate sink marks on the holding lip. Since it was not possible, it was insufficient to prevent a decrease in the assembly force.

  The present invention has been devised in view of these problems, and an object of the present invention is to provide an automobile opening trim that can be firmly assembled even at a corner portion of a vehicle body opening edge.

  The opening trim 1 for an automobile according to claim 11 is formed by extrusion molding, and the processing to the holding lip 11 according to any one of claims 1 to 10 is performed simultaneously with the extrusion molding.

  The automobile opening trim 1 according to claim 12 is formed by extrusion molding, and the processing to the holding lip 11 according to any one of claims 1 to 11 is performed in a separate process after the extrusion molding is completed. It is characterized by.

  The opening trim 1 for an automobile according to claim 1 includes a vehicle interior side wall portion 12, a vehicle exterior side wall portion 13, and a rear wall portion 14 that continuously connects the vehicle interior side wall portion 12 and the vehicle exterior wall portion 13. A lip portion 11 that has a letter-shaped mounting base 10 and that is inserted from the opening side of the substantially U-shaped cross section and that holds the flange 2 formed along the vehicle body opening edge of the automobile is formed on the inner side of the side wall portion. In the opening trim 1 provided, the holding lip 11 is configured to be capable of being contracted in the longitudinal direction, so that any portion including the corner portion C of the opening edge of the vehicle body can be firmly assembled.

  The opening trim 1 for an automobile according to claim 2 includes a vehicle interior side wall portion 12, a vehicle exterior wall portion 13, and a rear wall portion 14 that continuously connects the vehicle interior side wall portion 12 and the vehicle exterior wall portion 13. A lip portion 11 that has a letter-shaped mounting base 10 and that is inserted from the opening side of the substantially U-shaped cross section and that holds the flange 2 formed along the vehicle body opening edge of the automobile is formed on the inner side of the side wall portion. In the opening trim 1 provided, since the holding lip 11 is provided with one or more cuts 15 in the direction intersecting the longitudinal direction from the root or tip thereof, any one including the corner portion C of the opening edge of the vehicle body is provided. Even in the portion, it can be firmly assembled.

  That is, for example, by providing the incision 15 in a portion of the holding lip 11 that is assembled to the corner C of the opening edge of the vehicle body, the holding lip 11 is divided and cuts continuity, so that elongation due to bending is suppressed. . Therefore, the holding lip 11 is very elastic in contact with the flange 2 without falling in the direction of the side wall 12 because the force for restoring the elongation to the original state is very weak. As a result, the opening trim 1 can be firmly assembled to the flange 2.

  This is particularly effective at the two rear corner portions C1 where the plate thickness of the flange 2 is thin and located on the rear side of the rear door, and it is possible to reliably prevent the opening trim 1 from falling off at the rear corner portion C1. it can.

  In addition, in the straight part S of the opening edge of the vehicle body, the holding lip 11 provided with the notch 16 in the part where the number of the flange plates 2 to be combined or the wall thickness is changed is minimized. It can be suppressed. Therefore, the holding lip 11 is elastically brought into contact with the flange 2 without falling in the direction of the vehicle interior side wall portion 12. Thereby, the opening trim 1 can be firmly assembled to the flange 2.

  The opening trim 1 for an automobile according to claim 3 has one or more notches 16 provided in the holding lip 11 in the direction intersecting the longitudinal direction from the root or tip thereof. Similar to the invention, the holding lip 11 does not extend greatly due to bending at the corner portion C or a change in the thickness of the flange 2 at the straight portion S. Therefore, it is not tilted by the accompanying restoring force. As a result, the corner portion C and the straight portion S can be firmly assembled.

  In the opening trim 1 for an automobile according to claim 4, the holding lip 11 is provided with one or more thin portions 17a thinner than other portions in a part in the longitudinal direction thereof. Since the restoring force due to the elongation due to the change in the thickness of the flange 2 in the straight portion S is absorbed by the elongation of the thin portion 17a, the holding lip 11 does not largely tilt and elastically contacts the flange 2. As a result, the opening trim 1 can be firmly assembled to the flange 2.

  In the opening trim 1 for an automobile according to claim 5, since the soft portion 17 b made of a material softer than other portions is arranged on a part of the holding lip 11 in the longitudinal direction, bending at the corner portion C or straight portion Since the restoring force accompanying the elongation due to the change in the wall thickness of the flange 2 in S is absorbed by the elongation of the soft portion 17b, the holding lip 11 does not tilt greatly and strongly contacts the flange 2. As a result, the opening trim 1 can be firmly assembled to the flange 2.

  The holding lip 11 in the opening seal according to any one of claims 2 to 5 is disconnected from the continuity by the notch 15, the notch 16 thin portion 17a, or the soft portion 17b, and can be elastically deformed locally. In both the corner portion C and the straight portion S, the insertion workability with respect to the flange 2 is excellent. Accordingly, the flange 2 can be easily assembled.

  Moreover, the flexibility is increased by forming the cut 15 and the like, and the effect of facilitating handling at the time of packing work or assembling work is also exhibited.

  The opening trim 1 for an automobile according to claim 6 exhibits the same effect as the invention according to claims 2 to 5. Further, since the notch 15, the notch 16, the thin portion 17a, or the soft portion 17b is provided from the tip to the root of the holding lip 11, the continuity of the holding lip 11 can be more reliably cut off. Thereby, the elongation at the corner portion C and the like and the generation of the restoring force associated therewith can be further suppressed, and the tilting of the holding lip 11 can be further reliably prevented. As a result, the opening trim 1 can be more firmly assembled to the flange 2.

  The opening trim 1 for an automobile according to claim 7 exhibits the same effect as the invention according to claims 2 to 6. Further, since the notch 15, the notch 16, the thin portion 17a, or the soft portion 17b is provided at least in the portion of the holding lip 11 that is assembled to the corner portion C of the opening edge of the vehicle body, for the reason described above, the corner portion C Can be firmly assembled.

  The notch 15, the notch 16 thin portion 17a, or the soft portion 17b provided in the direction intersecting the longitudinal direction alleviates elongation due to bending to follow the corner portion C of the opening edge of the vehicle body and prevents sink marks. For this purpose, it is more effective to provide it at the base of the lip located on the outer peripheral side of the bending than on the lip tip located on the inner peripheral side of the bending. However, considering the ease of processing, the tip of the lip may be sufficient, and the effect of preventing sink marks can be sufficiently obtained.

  The opening trim 1 for an automobile according to an eighth aspect exhibits the same effects as the inventions according to the second to seventh aspects. In addition, since a plurality of notches 15, notches 16, thin portions 17a, or soft portions 17b are provided and two or more of them are arranged in parallel to each other, molding is easy and accurate.

That is, for example, when forming the cut 15, it can be considered that a cutting device is provided in the extrusion line of the opening trim 1, but in this case, the processing of making the plurality of cuts 15 in parallel is not so. Compared to the case, the control of the cutting device and the die of the extrusion molding machine becomes easier and more accurate, so that molding can be performed easily and accurately.

  The automobile opening trim 1 according to the ninth aspect exhibits the same effects as the inventions according to the second to eighth aspects. Further, a plurality of notches 15, notches 16, thin portions 17a, or soft portions 17b are provided at equal intervals, or two or more of them are set as one set. Since the notches 16, the thin portions 17a, or the soft portions 17b are arranged so as to have at least one set having equal intervals, the molding can be performed easily and accurately.

  The interval between the cuts 15 and the like can be set narrow when the curvature of the corner portion C is large, and can be set wide when the curvature is small.

  The opening trim 1 for an automobile according to the tenth aspect exhibits the same effects as the inventions according to the second to ninth aspects. Further, since the notch 15, the notch 16, the thin portion 17a, or the soft portion 17b is provided in the direction perpendicular to the longitudinal direction of the holding lip 11, molding is easy and accurate in this case as well.

  Moreover, when forming the notch 16, the thin part 17a, and the soft part 17b, it is possible to carry out by slightly moving the die of the extruder while extruding, but also in this case, the notch 16 or the like is in the longitudinal direction. If the direction is perpendicular to the shape, molding is easy and accurate.

  Further, since the notches 15 and the like are provided in a direction perpendicular to the longitudinal direction of the holding lip 11, when the opening trim 1 is assembled to the flange 2, the notches 15 and the like are in a posture perpendicular to the longitudinal direction of the flange 2. . Therefore, unlike the case of the inclined posture, the problem that the holding lip 11 is turned up does not occur.

  The opening trim 1 for an automobile according to claim 11 is formed by extrusion molding, and the processing to the holding lip 11 according to any one of claims 1 to 10 is performed simultaneously with the extrusion molding, so that the productivity is high.

  The opening trim 1 for an automobile according to claim 11 is formed by extrusion molding, and the processing to the holding lip 11 according to any one of claims 1 to 10 is performed in a separate process after the extrusion molding is completed. Even when it is difficult to install a processing device for the holding lip 11 in the extrusion process, or when the actual holding lip 11 needs to be quickly processed due to a market failure or the like, it is possible to cope with it.

  A first embodiment of an automotive opening trim 1 according to the present invention is shown in FIGS. 1, 2 and 4. The opening trim 1 is formed by extrusion molding as a whole, and includes a vehicle interior side wall portion 12, a vehicle exterior wall portion 13, a vehicle interior side wall portion 12, and a vehicle exterior wall portion 13 provided with a holding lip 11 protruding therefrom. And a mounting base 10 having a substantially U-shaped cross section.

  The mounting base 10 is integrally formed with a hollow seal portion 18 that elastically contacts the door and an interior trim 19 that abuts the interior material. Further, a plurality of ribs 13 a are integrally projected from the inner surface of the vehicle outer side wall portion 13 and elastically contacted with the flange 2. This opening trim 1 is assembled by inserting a mounting base 10 into a flange 2 formed along an opening edge of a vehicle body of an automobile by inserting the mounting base 10 from the opening side having a substantially U-shaped cross section.

  In addition, the opening trim 1 is provided with a plurality of cuts 15 having a width of 1 mm or less in the direction intersecting the longitudinal direction from the tip to the root of the holding lip 11. In the present embodiment, the cuts 15 are formed in portions of the holding lip 11 that are assembled to the plurality of corner portions C, respectively.

  Since this opening trim 1 has a plurality of cuts 15 formed in the portion of the holding lip 11 that is assembled to the corner portion C, the continuity in that portion is broken, and therefore, the opening trim 1 is bent when assembled to the corner portion C. Even so, the elongation caused thereby is suppressed. For this reason, the holding lip 11 is strongly weakened by the flange 2 without being tilted in the direction of the vehicle interior side wall portion 12 because the force for restoring the elongation to the original state is very weakened. As a result, the opening trim 1 can be firmly assembled to the flange 2, and in particular, the opening trim 1 can be removed at the two rear corners C <b> 1 located on the rear side of the rear door where the flange 2 is thin. It can be surely prevented.

  The notch 15 can be formed not only in the portion of the holding lip 11 assembled to the corner portion C but also in the straight portion S. In that case, even if the thickness of the flange 2 is changed, the elongation due to the change can be minimized. Therefore, the holding lip 11 does not fall down in the direction of the vehicle interior side wall portion 12 but elastically contacts the flange 2, and the opening trim 1 can be firmly attached to the flange 2 even in the straight portion S.

  In addition, the opening trim 1 is provided with a plurality of cuts 15 in parallel in the direction perpendicular to the longitudinal direction of the holding lip 11 at equal intervals. The incision 15 is formed by providing an incision device in the extrusion molding line and processing the holding lip 11 after the extrusion molding. The incision 15 is formed by providing the incisions 15 in the vertical direction and at equal intervals. Can be performed easily and accurately.

  Note that the interval between the cuts 15 can be set narrow when the curvature of the corner portion C is large, and can be set wide when the curvature is small.

  A second embodiment of an automotive opening trim 1 according to the present invention is shown in FIGS. 1, 2 and 5. The feature of the opening trim 1 is that a plurality of notches 16 having a width of 2 to 3 mm are provided on the portion of the holding lip 11 that is assembled to the corner portion C in the direction intersecting the longitudinal direction from the tip to the root. It is. This notch 16 can also be provided in the straight line portion S. The width of the notch 16 is preferably formed in a range not exceeding 3 mm. If it is larger, water or sound may enter the room through the notch 16.

  By providing a plurality of cutouts 16, as in the first embodiment, the holding lip 11 is prevented from extending at the corner portion C (and the straight portion S), and the accompanying restoring force is prevented from being generated. Thus, the holding lip 11 can be prevented from tilting. As a result, the holding lip 11 can be strongly elastically contacted with the flange 2, and the opening trim 1 can be firmly assembled to the flange 2. Thereby, in particular, it is possible to reliably prevent the opening trim 1 from dropping off at the rear corner portion C1 where the flange 2 is thin.

  A third embodiment of an automotive opening trim 1 according to the present invention is shown in FIG. 1, FIG. 2 and FIG. The opening trim 1 is characterized in that a plurality of thin portions 17a each having a width of about 5 mm are provided in a portion that is assembled to the corner portion C of the holding lip 11 from the tip to the root in a direction intersecting the longitudinal direction. Yes. The thin portion 17a is formed by providing a recess on the back wall portion 14 side of the holding lip 11, but can also be formed by providing a recess on the opposite side. The thin portion 17a can also be formed in the straight portion S.

  In addition, it is preferable that the thin portion 17 a is set at a tip portion of the holding lip 11 to be equal to or less than half of the thickness of the holding lip 11. If it is thicker than that, tilting of the holding lip 11 may not be sufficiently prevented. The width of the thin portion 17 is preferably set to 2 mm to 5 mm. If it is narrower than that, tilting of the holding lip 11 cannot be sufficiently prevented, and if it is wider than that, water and sound may enter the room.

  Since the opening trim 1 is provided with a plurality of thin portions 17a, the restoring force accompanying the extension of the holding lip 11 at the corner portion C (and the straight portion S) is increased as the thin portion 17a is extended, as in the above embodiment. Therefore, it is possible to prevent the holding lip 11 from being largely inclined. As a result, the holding lip 11 can be strongly brought into elastic contact with the flange 2, and the opening trim 1 can be firmly assembled to the flange 2. Thereby, in particular, it is possible to reliably prevent the opening trim 1 from dropping off at the rear corner portion C1 where the flange 2 is thin.

  A fourth embodiment of an automotive opening trim 1 according to the present invention is shown in FIGS. 1, 2 and 7. The opening trim 1 is characterized in that a plurality of soft portions 17b having a width of about 5 mm are provided at a portion that is assembled to the corner portion C of the holding lip 11 from the tip to the root in a direction intersecting the longitudinal direction. Yes. In addition, this soft part 17b can also be formed in the straight part S.

  The soft part 17b may be provided in all the cross-sectional directions of the holding lip 11, or may be provided in a part of the cross section. Moreover, although the longitudinal direction width | variety of the soft part 17b is not specified in particular, it is preferable to form in the range which does not exceed 5 mm. If it is larger than that, there is a risk of lowering the holding power.

  Since the opening trim 1 is provided with a plurality of soft portions 17b, the restoring force accompanying the extension of the holding lip 11 at the corner portion C (and the straight portion S) is extended to the extension of the soft portion 17b. Therefore, it is possible to prevent the holding lip 11 from being largely inclined. As a result, the holding lip 11 can be strongly brought into elastic contact with the flange 2, and the opening trim 1 can be firmly assembled to the flange 2. Thereby, in particular, it is possible to reliably prevent the opening trim 1 from dropping off at the rear corner portion C1 where the flange 2 is thin.

  Installation of the soft portion 17b may be performed by extruding a normal material and a softer material alternately to the lip portion during extrusion molding, or a portion of the holding lip once extruded with a normal material. And a soft material may be filled in the cut-out portion by molding.

  Note that the holding lip 11 in the opening seal according to the above embodiment is elastically deformed locally because the continuity is cut off by the notch 15, the notch 16, the thin portion 17a, or the soft portion 17b. Therefore, since the flexibility is increased, there is an advantage that handling at the time of packing work or assembling work becomes easy.
