Abstract
Description
Technical Field
[0001] The present invention relates to an elongated strip forming part which is fitted along the upper edge of the door panel of a vehicle door and seals between the door panel and the window panel. Background Technology
[0002] Typically, for vehicle doors that open / close the vehicle body, a window opening is provided, and a window panel (window glass) is installed to open / close the window opening, allowing it to move up and down. Furthermore, a slender strip-shaped component that seals between the door panel and the window panel is attached to the upper edge of the door panel. When the window panel moves up and down, the strip-shaped component slides against the window panel, thereby wiping away foreign matter (water droplets, grit, dust, etc.) adhering to the surface of the window panel (see, for example, Patent Document 1).
[0003] For example, in the prior art described in Patent Document 1, the strip-formed part has a vehicle interior sealing lip 32 that contacts the window panel and a decorative sealing lip 31 that protrudes from the upper end of the strip-formed part. When the window panel moves upward from the open position to the closed position, these sealing lips rub against each other, simultaneously sealing the space formed between the two sealing lips.

[0007] Technical issues
[0008] However, in the prior art disclosed in Patent Document 1, when the window panel is closed (moved upwards), friction is generated if the end of the inner sealing lip of the vehicle rubs against the lower surface of the decorative sealing lip. As a result, the end of the inner sealing lip of the vehicle becomes difficult to bend smoothly, and the load increases when the window panel is closed.
[0009] The present invention was made in view of the above circumstances, and its object is to provide a strip-formed part that can prevent the load from increasing when the window panel is closed.
[0010] Solution to the problem
[0011] To address the aforementioned problems, the invention described in Means 1 is an elongated strip forming component to be fitted along the upper edge of a door panel and to seal between the door panel and a window panel. The strip forming component includes: an outer sidewall portion and an inner sidewall portion facing each other in cross-section; a top wall portion connecting the sidewall portions; an inner lip portion protruding from the inner sidewall portion toward the inside of the vehicle; and a folded-back lip portion folding back from the end of the inner lip portion and protruding toward the inner sidewall portion. And a decorative lip that protrudes from the portion of the inner sidewall portion of the vehicle that is above the inner sidewall portion toward the inner side of the vehicle, wherein at least one first protrusion is formed on the inner sidewall portion of the vehicle on the inner side of the vehicle in cross section at a position between the inner sidewall portion and the decorative lip, and wherein, when the inner sidewall portion bends toward the outer side of the vehicle, the groove formed between the inner sidewall portion and the inner sidewall portion of the vehicle is blocked by the folded-back lip and the decorative lip, and the folded-back lip is slidable relative to the first protrusion.
[0012] Therefore, according to the invention described in Means 1, when the inner lip of the vehicle bends outward as the window panel closes, the contact area of the folded-back lip at the end of the inner lip is smaller than the contact area when it slides in contact with the apex of the first protrusion formed on the inner sidewall of the vehicle, since it slides in contact with the inner surface of the inner sidewall of the vehicle. At the same time, since the frictional force generated between the folded-back lip and the inner sidewall of the vehicle is also reduced, the inner lip can bend smoothly, and thus, an increase in load when the window panel is closed can be prevented.
[0013] Examples of materials used to form elongated strips include thermoplastic elastomers, thermoplastic resins, and rubber. As thermoplastic elastomers, olefin-based thermoplastic elastomers (TPO) and styrene-based elastomers (TPS) are preferred. Furthermore, as thermoplastic resins, vinyl chloride resin (PVC resin) and polypropylene resin (PP resin) are preferred. Furthermore, as rubber, ethylene propylene diene monomer (EPDM) rubber is preferred.
[0014] To address the aforementioned problems, the invention described in Means 2 is an elongated strip forming member to be fitted along the upper edge of a door panel and to seal between the door panel and a window panel. The strip forming member includes: an outer sidewall portion and an inner sidewall portion facing each other in cross-section; a top wall portion connecting the sidewall portions; an inner lip portion protruding from the inner sidewall portion toward the inside of the vehicle; a folded-back lip portion folded back from the end of the inner sidewall portion and protruding toward the inner sidewall portion; and a decorative lip portion extending from the portion of the inner sidewall portion above the inner lip portion toward the vehicle. The vehicle interior protrudes, wherein at least one of the outer surface of the folded-back lip and the lower surface of the decorative lip is covered by a sliding material, wherein the sliding material used to cover the outer surface of the folded-back lip has the same hardness as the material used to form the vehicle interior lip, wherein the sliding material used to cover the lower surface of the decorative lip has the same hardness as the material used to form the decorative lip, and wherein, when the vehicle interior lip bends outward, the groove formed between the vehicle interior lip and the vehicle interior sidewall is closed by the folded-back lip and the decorative lip, and the outer surface of the folded-back lip can slide relative to the lower surface of the decorative lip via the sliding material.
[0015] Therefore, according to the invention described in Means 2, when the vehicle inner lip bends outwards as the window panel closes, the outer surface of the folded-back lip at the end of the vehicle inner lip and the lower surface of the decorative lip protruding from the vehicle inner sidewall slide via a sliding material. Thus, compared to the case where the outer surface of the folded-back lip and the lower surface of the decorative lip slide without the sliding member, the frictional force generated between the folded-back lip and the decorative lip is less. As a result, the vehicle inner lip can bend smoothly, and therefore, an increase in load when the window panel is closed can be prevented. Furthermore, the hardness of the sliding material used to cover the outer surface of the folded-back lip is approximately the same as the hardness of the material used to form the vehicle inner lip, and the hardness of the sliding material used to cover the lower surface of the decorative lip is approximately the same as the hardness of the material used to form the decorative lip. Therefore, even when the sliding material is covered, the original flexibility of each lip is not compromised.
[0016] Regarding means 2, in the invention described in means 3, on the inner sidewall of the vehicle, at least one first protrusion is formed in cross-section at a position between the inner lip of the vehicle and the decorative lip, and the folded lip is slidable relative to the first protrusion when the inner lip of the vehicle bends outward toward the vehicle.
[0017] Therefore, according to the invention described in Means 3, when the inner lip of the vehicle bends outward, the contact area of the folded-back lip at the end of the inner lip is smaller than the contact area when it slides in contact with the apex of the first protrusion formed on the inner sidewall of the vehicle, since it slides in contact with the inner surface of the inner sidewall of the vehicle. At the same time, the frictional force generated between the folded-back lip and the inner sidewall of the vehicle is also reduced, allowing the inner lip to bend more smoothly.
[0018] Regarding means 1 or 3, in the invention described in means 4, the recess is formed on the lower side of the first protrusion on the inner sidewall of the vehicle.
[0019] Therefore, according to the invention described in Means 4, since the first protrusion increases higher as the concave portion is formed, it is possible to make it difficult for the folded lip portion to contact the inner surface of the vehicle inner sidewall portion.
[0020] Regarding one of means 1 to 4, in the invention described in means 5, at least one second protrusion is formed on the lower surface of the decorative lip in cross-section.
[0021] Therefore, according to the invention described in Means 5, when the inner lip of the vehicle bends outward, the folded-back lip at the end of the inner lip slides in contact with the second protrusion and is guided toward the inner sidewall of the vehicle. Therefore, the frictional force is less than in the case where it slides in overall contact with the lower surface of the decorative lip. Thus, the folded-back lip can be smoothly guided toward the inner sidewall of the vehicle.
[0022] With respect to any of means 1 to 5, in the invention described in means 6, the thickness of the root side of the folded-back lip is less than the thickness of the end side of the folded-back lip.
[0023] Therefore, according to the invention described in Means 6, by thinning the root side of the curved portion of the folded lip, the folded lip can be easily bent.
[0024] With respect to any of means 1 to 6, in the invention described in means 7, the end portion of the folded-back lip bends toward the interior of the groove, and the curvature of the folded-back lip at the end portion is greater than the curvature at the base portion.
[0025] Therefore, according to the invention described in Means 7, when the inner lip of the vehicle bends outward, the folding lip can fold and bend smoothly without being blocked (push up) by the inner sidewall of the vehicle.
[0026] Beneficial effects of the present invention
[0027] As described above, according to the present invention, it is possible to prevent an increase in load when the window panel is closed. Attached Figure Description

[0054] Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.
[0055] like Figure 1 As shown, for the door 1, which opens / closes the vehicle body, a window opening 2 is provided, and a window panel 3 (window glass) for opening / closing the window opening 2 is installed so that it can move up and down. An elongated strip-formed member 10 is attached to the door 1 along the upper edge of the door panel 4 (in other words, the lower edge of the window opening 2). In this embodiment, the door panel 4 is the outer door panel, and the strip-formed member 10 in this embodiment is an external strip-formed member that seals between the door panel 4 and the window panel 3. Note that when the window panel 3 moves up and down, foreign matter (water droplets, grit, dust, etc.) adhering to the surface 3a of the window panel 3 is wiped away by the strip-formed member 10.
[0056] also, Figure 1 The diagram shows the strip-formed component 10 attached to the front and rear doors on the left side of the vehicle body, but similar strip-formed components 10 are also attached to the front and rear doors on the right side of the vehicle body. Therefore, in this embodiment, only the strip-formed component 10 attached to the left front door is described, and the description of the strip-formed components 10 attached to the left rear door, right front door, and right rear door is omitted.
[0057] Furthermore, the strip-formed part 10 of this embodiment is an extruded product formed using an olefin-based thermoplastic elastomer (TPO), and is uniformly formed along its entire length. For example... Figure 2 As shown, the strip-formed part 10 has a body portion 11 with a generally U-shaped cross-section. The body portion 11 has: an outer vehicle sidewall portion 12 and an inner vehicle sidewall portion 13 facing each other in cross-section; and a top wall portion 14 connecting the upper edges of the sidewall portions 12 and 13 to each other. On the other hand, the end portion (upper edge portion) of the door panel 4 is processed (rolled) into a folded state to form a flange 4a. Then, the strip-formed part 10 is attached to the flange 4a by inserting the flange 4a between the outer vehicle sidewall portion 12 and the inner vehicle sidewall portion 13.
[0058] Furthermore, a locking portion 15, curving outwards towards the vehicle's outer side, is provided at the lower end of the vehicle's inner sidewall portion 13. When the strip-formed part 10 is attached to the door panel 4, the locking portion 15 is locked by the end edge (lower edge) of the folded-back portion 4b of the flange 4a. Additionally, the vehicle's inner sidewall portion 13 is provided with an inner lip 16, which protrudes from the vehicle's inner sidewall portion 13 toward the window panel 3 (vehicle interior). In the initial state, the inner lip 16 protrudes obliquely upwards from the lower side of the vehicle's inner sidewall portion 13 (see...). Figure 2 The inner lip 16 of the vehicle is adapted to bend toward the outer side of the vehicle (towards the inner sidewall 13 of the vehicle) by rotating about the root of the inner lip 16 in the direction of arrow F1 (see...). Figure 3 Note that the thickness of the root (base end) and end of the inner lip 16 is less than the thickness of the central part of the inner lip 16.
[0059] like Figure 2 As shown, the inner lip 16 of the vehicle is provided with a folded-back lip 17, which folds back from the end side of the inner lip 16 and protrudes toward the inner sidewall portion 13 (outer side of the vehicle). The folded-back lip 17 protrudes from the end of the inner lip 16, specifically, from a position slightly closer to the base (root) than the end of the inner lip 16. Note that the thickness of the root side of the folded-back lip 17 is less than the thickness of the end side of the folded-back lip 17. The end portion 19 of the folded-back lip 17 bends toward the inside of the groove A1 formed between the inner lip 16 and the inner sidewall portion 13 of the vehicle, and the curvature of the folded-back lip 17 at the end portion 19 is greater than the curvature at the base portion 18.
[0060] Furthermore, the outer sidewall portion 12 of the vehicle is provided with a retaining lip 20 protruding toward the inner sidewall portion 13 of the vehicle (inner side). The retaining lip 20 protrudes obliquely upward from the lower end of the outer sidewall portion 12. On the other hand, a retaining protrusion 21 is formed on the outer surface 13a of the inner sidewall portion 13 of the vehicle at a position that is approximately the center of the inner sidewall portion 13. In this embodiment, the retaining protrusion 21 is along the length direction of the strip forming member 10 ( Figure 2 An elongated protrusion extending in the depth direction of the strip forming member 10 is formed along its entire length. When the strip forming member 10 is attached to the door panel 4, the retaining lip 20 and the retaining protrusion 21 are adapted to clamp the flange 4a while simultaneously making elastic contact with it. Furthermore, a vehicle outer recess 22 is formed at the lower side of the retaining protrusion 21 of the vehicle inner sidewall portion 13, and the lower region of the vehicle outer surface 13a of the vehicle outer recess 22 contacts the side surface of the folded-back portion 4b of the flange 4a.
[0061] In addition, such as Figure 2As shown, the outer surface 12a of the outer sidewall portion 12 and the outer (upper) surface 14a of the top wall portion 14 are covered by a cover portion 23 with a good appearance. Furthermore, an outer lip 24 is provided at the position where the outer sidewall portion 12 and the retaining lip 20 are connected. When the strip-formed member 10 is attached to the door panel 4, this outer lip 24 fills the gap between the strip-formed member 10 and the door panel 4. The outer lip 24 protrudes downward from the lower end of the outer sidewall portion 12, and the end of the outer lip 24 curves towards the inside of the vehicle.
[0062] Furthermore, a decorative lip 25 protruding towards the inside of the vehicle is located above the inner lip 16 on the inner sidewall portion 13 and serves as a connection point with the top wall portion 14. The decorative lip 25 curves slightly downward and has a length that does not contact the window panel 3.
[0063] like Figure 2 As shown, on the inner surface 13b of the inner sidewall portion 13, a first protrusion 26 is formed at a position between the inner lip 16 and the decorative lip 25 in cross-section. In this embodiment, the first protrusion 26 is an elongated projection, positioned directly below the decorative lip 25 and along the length of the strip forming member 10. Figure 2 The first protrusion 26 extends along the entire length of the strip 10. Furthermore, the first protrusion 26 protrudes from the surface 13b of the inner sidewall portion 13 of the vehicle and has a generally triangular shape in cross-section. More specifically, the first protrusion 26 has a protrusion height h1 less than the width w1 and a gentle shape without corners. Additionally, an inner recess 27 is formed on the inner sidewall portion 13 of the vehicle below the first protrusion 26.
[0064] In addition, such as Figure 2 As shown, in cross-section, a second protrusion 28 is formed on the lower surface 25a of the decorative lip 25. In this embodiment, the second protrusion 28 is an elongated projection disposed at the end of the decorative lip 25 and extending along the length direction of the strip forming member 10. The second protrusion 28 is formed along the entire length direction of the strip forming member 10. Furthermore, the second protrusion 28 protrudes from the lower surface 25a of the decorative lip 25 and has a generally triangular shape in cross-section. More specifically, the second protrusion 28 has a protrusion height h2 less than the width w2 and a gentle shape without corners. On the surface of the second protrusion 28, the region on the end side of the decorative lip 25 serves as a guide surface 28a for guiding the return lip 17 into the groove A1.
[0065] Note that the body portion 11 (the outer sidewall portion 12, the inner sidewall portion 13, and the top wall portion 14) has an indicated hardness of 70 degrees (Type D) as defined in JIS K7215. On the other hand, the inner lip 16, the folding lip 17, the retaining lip 20, the outer lip 24, and the decorative lip 25 are made of a softer and more elastically deformable material than the body portion 11. Each of the lips 16, 17, 20, 24, and 25 has an indicated hardness of 70 degrees (Type A) as defined in JIS K7215.
[0066] Furthermore, the strip forming part 10 is formed by co-extruding the body part 11 and each lip part 16, 17, 20, 24 and 25. Then, secondary processing for attaching the strip forming part 10 to the door 1, such as stamping, cutting, etc., is performed at both ends of the strip forming part 10 in the length direction.
[0067] Next, the method of using the strip forming part 10 will be described.
[0068] For example, when the window panel 3 is in the open position (lower position) and the window opening 2 is in the open state (see...) Figure 2 The inner lip 16 of the vehicle with the molded part 10 is in a state of not contacting the window panel 3.
[0069] Then, as the window panel 3 moves upward from the open position to the closed position (upper position) and the window opening 2 moves to the closed state (see... Figure 3 The upward-moving window panel 3, surface 3a, contacts the end of the vehicle's inner lip 16. Furthermore, as the window panel 3 continues to move upward, the vehicle's inner lip 16 is pushed against the window panel 3 and bends towards the vehicle's inner sidewall 13 (outer side of the vehicle) (see reference). Figure 3 (In the direction of the middle arrow F1). Note that at this time, the inner lip 16 of the vehicle makes sliding contact with the window panel 3, so that the foreign matter adhering to the surface 3a of the window panel 3 is wiped away.
[0070] Furthermore, when the inner lip 16 bends toward the inner sidewall portion 13 (outer side of the vehicle), the outer surface 17a of the folded-back lip 17 protruding from the inner lip 16 contacts the guide surface 28a of the second protrusion 28 of the decorative lip 25 protruding from the inner sidewall portion 13. Then, as the outer surface 17a slides against the guide surface 28a of the second protrusion 28, the folded-back lip 17 is guided downward at an angle (into the groove A1 formed between the inner lip 16 and the inner sidewall portion 13) (see...). Figure 3Furthermore, the outer surface 17a of the folded-back lip 17 slides while in contact with the vertex P1 of the first protrusion 26 provided on the inner sidewall portion 13 of the vehicle, and then slides against the surface 26a of the first protrusion 26 below the vertex P1 (see...). Figure 3 As a result, the opening on the upper side of the groove A1 is blocked by the folded-back lip 17 and the inner sidewall portion 13 of the vehicle (and the decorative lip 25). Note that due to deviations in the position of the strip-formed part 10 (specifically, deviations in the position of the folded-back lip 17, the decorative lip 25, etc.) or deviations in the position of the window panel 3, the folded-back lip 17 does not need to slide against the surface 26a of the first protrusion 26. For example, the folded-back lip 17 may only contact the apex P1 of the first protrusion 26, or the folded-back lip may not contact the first protrusion 26 itself.
[0071] Therefore, according to this embodiment, the following effects can be obtained.
[0072] (1) In the strip-formed part 10 of this embodiment, when the inner lip 16 bends outwards as the window panel 3 closes, the folded-back lip 17 at the end of the inner lip 16 slides in contact with the apex (apex P1) of the first protrusion 26 formed on the inner sidewall portion 13. Therefore, compared to the case where the folded-back lip 17 slides in contact with the inner surface 13b of the inner sidewall portion 13, the contact area between the folded-back lip 17 and the inner sidewall portion 13 is smaller. At the same time, since the frictional force generated between the folded-back lip 17 and the inner sidewall portion 13 is also reduced, the inner lip 16 can bend smoothly, and therefore, the increase in load when the window panel 3 is closed can be prevented.
[0073] (2) Furthermore, in this embodiment, when the window panel 3 is opened, the inner lip 16 of the vehicle also returns to its initial state (see Figure 2 When moving (towards the inside of the vehicle), the return lip 17 slides in contact with the apex of the first protrusion 26. Therefore, the contact area is smaller compared to the case where the return lip 17 slides in contact with the inner surface 13b of the inner sidewall portion 13 of the vehicle. At the same time, since the frictional force generated between the return lip 17 and the inner sidewall portion 13 of the vehicle is also reduced, the inner lip 16 can easily return to its initial state, and therefore, the performance of wiping away foreign matter adhering to the surface 3a of the window panel 3 can be well maintained.
[0074] (3) In this embodiment, both the first protrusion 26 and the second protrusion 28 are along the length direction of the strip forming part 10. Figure 1The first protrusion 26 and the second protrusion 28 are elongated protrusions that extend in the front-rear direction and are formed along the entire length of the strip forming part 10. Therefore, when the strip forming part 10 is formed by extrusion molding, the first protrusion 26 and the second protrusion 28 can be formed simultaneously with each of the lips in the body part 11, lip parts 16, 17, 20, 24 and 25. In addition, when the window panel 3 is closed, the groove A1 is blocked by the folded-back lip 17 and the inner side wall part 13 of the vehicle (and the decorative lip 25), thus preventing foreign objects from entering the groove A1. Furthermore, when the window panel 3 is closed, wind noise caused by air entering the groove A1 can be prevented.
[0075] Note that the above embodiments can be modified as follows.
[0076] • In the above embodiment, the cross-section on the inner surface 13b of the inner sidewall portion 13 of the vehicle (see Figure 2 In this configuration, a first protrusion 26 is formed at a position between the inner lip 16 and the decorative lip 25. However, more than two first protrusions 26 may also be formed. For example, although... Figure 2 The first protrusion 26 is formed directly below the decorative lip 25, but another first protrusion 26 may be further formed at... Figure 2 The position below the center (specifically, the position between the first protrusion 26 on surface 13b and the root of the inner lip 16 of the vehicle) is where the folded lip 17 can slide.
[0077] In the above embodiment, in cross-section, a second protrusion 28 is formed on the lower surface 25a of the decorative lip 25 (see...). Figure 2 However, more than two second protrusions 28 can also be formed. For example, although in Figure 2 The second protrusion 28 is formed at the end of the decorative lip 25, but another second protrusion 28 may be further formed at the base end of the decorative lip 25.
[0078] • In the above embodiments, the cross-sections of the first protrusion 26 and the second protrusion 28 are both approximately triangular, but they may also have other shapes, such as a roughly rectangular cross-section and a roughly semi-circular cross-section.
[0079] • In this embodiment, both the first protrusion 26 and the second protrusion 28 are along the length direction of the strip forming member 10. Figure 1 The first protrusion 26 and the second protrusion 28 are elongated protrusions that extend in the front-back direction and are formed along the entire length of the strip forming member 10. However, each of the first protrusion 26 and the second protrusion 28 may be composed of a plurality of protrusions arranged along the length direction of the strip forming member 10 or a plurality of short protrusions arranged along the length direction of the strip forming member 10.
[0080] ·like Figure 4As shown, the body portion 11 can be formed of a relatively soft material (e.g., an olefin-based thermoplastic elastomer (TPO) with an indicated hardness (Type A) of 70 as defined in JIS K7215), and a core material 31, such as a metal plate, can be embedded in the body portion 11 to impart hardness. Furthermore, the surface of the first protrusion 26 can be covered by a cover portion 32, which is made of a material that slides more easily than the body portion 11 (e.g., an olefin-based thermoplastic elastomer with an indicated hardness (Type D) of 0 as defined in JIS K7215). Additionally, the surface of the first protrusion 26 can be covered by a cover portion 32, which is made of a material with a hardness equal to or greater than that of the body portion 11 (e.g., the inner sidewall portion 13 of the vehicle) (e.g., a material with an indicated hardness (Type D) of 40 as defined in JIS K7215 or a material with a hardness defined in JIS A70 to 85). Note that the cover portion 32 can cover the surface of the end portion 19 of the folded-back lip 17, the surface of the second protrusion 28, etc.
[0081] ·like Figure 5 As shown, the outer surface 17a of the folded-back lip 17 may be covered by a soft sliding material 42 (sliding material) with a hardness (e.g., the hardness defined in JIS A70 to 85) that is substantially the same as the hardness of the material used to form the inner lip 16 of the vehicle. Specifically, in addition to the outer surface 17a, the soft sliding material 42 may also cover all or part of the surface of the end portion 19 and the base portion 18 of the folded-back lip 17. Furthermore, the lower surface 25a of the decorative lip 25 may be covered by a soft sliding material 41 (sliding material) with a hardness (e.g., the hardness defined in JIS A70 to 85) that is substantially the same as the hardness of the material used to form the decorative lip 25. Specifically, in addition to the lower surface 25a of the decorative lip 25, the soft sliding material 41 may also cover all or part of the surface of the second protrusion 28 and the guide surface 28a of the second protrusion 28. Note that either the soft sliding materials 41 and 42 may be omitted.
