Description

  The present invention relates to a belt molding that is mounted along a window opening edge so as to cover a space between a window plate that opens and closes a window opening of a vehicle body and an edge of the window opening and wipes off foreign matter adhering to the window plate surface. is there.

  In this type of belt molding, the sealing lip provided integrally with the belt molding is elastically contacted with the window plate surface, so that the gap between the window plate and the window opening edge is covered with the sealing lip and the visibility is kept good. For this reason, there is a type in which foreign matter such as water droplets adhering to the window plate surface is wiped off by a seal lip when the window plate is opened and closed.

Further, as described in Patent Document 1 (Japanese Patent Laid-Open No. 8-282282), an upper lip and a lower lip are provided on the belt molding, and the upper lip is pivotally supported so that the window plate is lowered. There is an apparatus in which the upper lip is isolated from the window plate, and when the window plate is raised, the upper lip is elastically contacted with the window plate to improve the wiping performance of water droplets when the window plate is raised.
JP-A-8-282282 (second page, etc.)

  By the way, it is unavoidable in terms of manufacturing technology that the positional relationship between the belt molding and the window plate varies due to accumulation of dimensional variations and assembly errors of the belt molding, the window plate, and peripheral components. Furthermore, the positional relationship between the belt molding and the window plate may change depending on the movement position (movement locus) of the window plate when the window plate is opened and closed. For these reasons, it is practically difficult to make the positional relationship between the belt molding and the window plate constant regardless of the position of movement of the window plate for each window of each vehicle. In the conventional belt molding, when the positional relationship between the belt molding and the window plate changes, the contact state between the seal lip provided on the belt molding and the window plate surface changes, and the window plate surface is favorable. There is a drawback that the wiping performance cannot be ensured.

  The present invention has been made in consideration of such circumstances, and therefore the object of the present invention is to ensure good wiping performance on the window plate surface even if the positional relationship between the belt molding and the window plate fluctuates. It is to provide a belt molding that can do.

  In order to achieve the above object, the invention according to claim 1 is directed to a window opening that covers between a window plate that opens and closes a window opening of a vehicle body and an edge of the window opening and wipes off foreign matter adhering to the window plate surface. A belt molding that is mounted along the edge, and is a long molding body part that is attached along the window opening edge, a distal end part that can be elastically contacted with the window plate surface, and a proximal end that is held on the molding body part side. A long wiper lip made of an elastic polymer material having a connecting portion for connecting the tip end portion to the base end portion so as to allow a swinging motion in which the tip portion and the tip end portion are tilted in the moving direction of the window plate, and a molding body portion The wiper lip base is provided so as to prevent the base end of the wiper lip from moving in the moving direction of the window plate and to allow the wiper lip to move in a direction close to or away from the window plate within a predetermined range. Wiper lip holding part for holding the end part and wiper The base end portion of the lip is obtained by a structure in which a wiper lip biasing means for urging the window plate side.

  In this configuration, when the belt molding is mounted along the edge of the window opening, the tip of the wiper lip is elastically contacted with the window plate surface, thereby covering the space between the window plate and the window opening edge with the wiper lip. When the plate is opened and closed, foreign matters such as water droplets adhering to the window plate surface can be wiped off at the tip of the wiper lip. Since the base end portion of the wiper lip is held by the wiper lip holding portion so as to be movable toward and away from the window plate and is biased toward the window plate by the wiper lip biasing means. Even if the positional relationship between the belt molding and the window plate fluctuates, the wiper lip can move accordingly, and the positional relationship between the wiper lip and the window plate can be held almost constant. It can be brought into elastic contact with the window plate surface with an appropriate pressing force. As a result, the positional relationship between the belt molding and the window plate varies due to individual differences between the vehicles and windows (part size variations, assembly errors, etc.), or the window plate moves when the window plate opens and closes. Even if the positional relationship between the belt molding and the window plate changes depending on the position, the tip of the wiper lip can always be brought into elastic contact with the window plate surface with an appropriate pressing force. Can be secured.

  In this case, the wiper lip connecting portion may be formed so that the thickness dimension in the moving direction of the window plate is thinner than the base end portion. In this way, it is possible to facilitate the swinging motion in which the tip of the wiper lip tilts in the moving direction of the window plate, and the wiper lip is elastically contacted with the window plate surface at an appropriate angle. be able to.

  Moreover, it is preferable to form an edge that contacts the window plate surface at the tip of the wiper lip. In this way, the edge of the wiper lip can be brought into linear contact with the window plate surface, and the tip of the wiper lip can be brought into contact with the window plate surface without any gap. The wiping performance against can be improved.

  Further, as in claim 4, the edge is formed on the first edge that contacts the window plate surface when the window plate moves in the opening direction, and on the window plate surface when the window plate moves in the closing direction. You may make it provide the 2nd edge which contacts. If it does in this way, the edge which contacts a window board surface can be switched whenever the moving direction of a window board reverses, the amount of wear of each edge can be reduced, and good wiping performance can be maintained for a long period of time. .

  According to a fifth aspect of the present invention, the wiper lip urging means may be composed of an elastic body that can be elastically deformed. In this way, the base end of the wiper lip can be urged by the elastic force when the elastic body is elastically deformed, and no additional energy or the like is required.

  In this case, as described in claim 6, the elastic body constituting the wiper lip urging means has an elastic deformation amount in a direction approaching and separating from the window plate larger than an allowable movement amount of the base end portion of the wiper lip. It is good to form like this. In this way, the base end portion of the wiper lip can be reliably urged by the wiper lip urging means (elastic body).

  Further, as in claim 7, the elastic body constituting the wiper lip urging means may use a metal spring. In this way, the base end portion of the wiper lip can be urged with a stable pressing force even under a high or low temperature environment.

  In this case, the metal spring may be a leaf spring or the like. However, as in claim 8, the coil spring is used to generate the wiper lip by the elastic force when elastically deformed by applying a load in the radial direction. The proximal end portion may be biased. In this way, the base end portion of the wiper lip can be urged using the elastic force of the coil spring in the radial direction, and the base end portion of the wiper lip can be applied over a long range of the entire length of the long coil spring. Can be energized.

  Further, as in claim 9, the elastic body constituting the wiper lip urging means is formed of an elastic polymer material into a long cylindrical shape, cylindrical shape or bellows shape, and is loaded in a direction intersecting the longitudinal direction. The base end portion of the wiper lip may be urged by the elastic force when it is elastically deformed by being applied. In this way, the wiper lip biasing means can be easily formed by extrusion molding or injection molding of the elastic polymer material.

  In this case, as in claim 10, the elastic body constituting the wiper lip urging means may be integrally formed with the wiper lip. If it does in this way, a number of parts can be reduced and an assembly man-hour can be reduced.

  Further, as in claim 11, the wiper lip urging means may be provided over substantially the entire length of the wiper lip. In this way, the base end of the wiper lip can be urged toward the window plate over almost the entire length, and the tip of the wiper lip can be biased over the entire length with an appropriate pressing force. Can be elastically contacted.

  Further, as in claim 12, a shielding lip that protrudes toward the window plate side may be provided in the molding body on the closing direction side of the window plate with respect to the wiper lip. If it does in this way, it can block with a shielding lip that a foreign object etc. penetrate | invade between a belt molding and a window board from the closing direction side of a window board. Further, the wiper lip can be concealed by the shielding lip, and there is an effect of preventing the decorativeness from being lowered.

  Further, as in claim 13, the present invention may be applied to an outer belt molding provided with an attachment portion that can be attached to a window opening edge on the vehicle exterior side of the window plate. In this way, foreign matter such as rainwater and mud adhering to the window plate surface outside the vehicle can be wiped off with the wiper lip.

  In this case, as in claim 14, when the window plate is curved with the outside of the vehicle as a convex surface, the wiper lip is held in a state in which the wiper lip is curved in a direction in which the front end portion becomes the concave side. It should be attached to the outside of the car. In this way, even when the window plate is curved with the outside of the vehicle as a convex surface, the tip of the wiper lip is curved in a concave shape so that the entire tip can be elastically contacted with the outer surface (convex surface) of the window plate. it can.

  Further, as in claim 15, the present invention may be applied to an inner belt molding provided with an attachment portion that can be attached to a window opening edge on the vehicle inner side of a window plate and / or an inner door trim. In this way, foreign matters such as water droplets adhering to the window plate surface inside the vehicle can be wiped off with the wiper lip.

  In this case, as in claim 16, when the window plate is curved with the inside of the vehicle as a concave surface, the wiper lip is held in a state in which the wiper lip is curved in a direction in which the tip portion becomes the convex side. It is better to install it inside the car. In this way, even if the window plate is curved with the inside of the vehicle as a concave surface, the tip of the wiper lip is curved in a convex shape so that the entire tip is elastically contacted with the inner surface (concave surface) of the window plate.

In this way, a structure in which the wiper lip unit integrated with the wiper lip or the wiper lip urging means attached to the wiper lip holding portion is attached to the molding body is also possible.

  Hereinafter, the best mode for carrying out the present invention will be described using five Examples 1 to 5.

A first embodiment of the present invention will be described with reference to FIGS.
As shown in FIG. 1, a window frame 12 is integrally provided on a front door 11 of an automobile, and a window plate 13 (window glass) that opens and closes a window opening formed by the window frame 12 can be moved up and down. Is provided. A long outer belt molding 16 is attached along the upper edge flange 15 to an upper edge flange 15 (see FIG. 2) provided at the upper edge of the outer door panel 14 (a window opening edge outside the vehicle). The outer belt molding 16 covers the space between the upper edge flange 15 of the outer door panel 14 and the window plate 13, and wipes off foreign matters such as rainwater and mud adhering to the vehicle outer surface 13 a of the window plate 13. Yes. In addition, since the inner belt molding attached to the vehicle inner side is not visually recognized from the vehicle outer side, it is omitted in FIG.

  Next, the configuration of the outer belt molding 16 will be described with reference to FIGS. As shown in FIG. 2, the molding main body portion 17 of the outer belt molding 16 is formed in a substantially inverted U-shaped cross section by extrusion molding of a polymer material, thereby forming a downward mounting groove G <b> 1 (attachment portion). The molding body 17 is formed in a long shape so as to extend along the upper edge flange 15 of the outer door panel 14, and a wiper lip, which will be described later, is formed on the side of the side wall 17 a on the vehicle interior side of the molding body 17. The holding part 18 is integrally formed.

  In addition, the molding body 17 includes a shielding lip 19 that protrudes from the upper end of the side wall 17a on the vehicle inner side toward the window plate 13 and a length that does not come into contact with the window plate 13 and the lower end of the side wall 17a on the vehicle inner side toward the window plate 13. A projecting contact lip 20, a cushion 21 projecting downward from the lower end of the side wall 17 b on the outside of the vehicle toward the outer door panel 14, and a resilient lip 22 projecting toward the outside of the vehicle from the side wall 17 b on the outside of the vehicle. And the some protrusion 23-26 which protrudes toward inner side from the internal peripheral surface of the molding main-body part 17 is fuse | fused by coextrusion molding, and is integrated.

  For example, a hard synthetic resin or the like is used as the polymer material for molding the molding body 17. Further, the polymer material that forms the shielding lip 19, the contact lip 20, the cushion portion 21, the elastic lip 22, and the protrusions 23 to 26 is a polymer material that is compatible with the polymer material that forms the molding body portion 17, For example, a thermoplastic elastomer that is softer and more elastic than the molding body 17 is used. Further, a low friction material layer 27 is formed on the surface of the contact lip 20 (at least the contact surface with the window plate 13) by flocking such as nylon pile, and is formed on the vehicle outer side of the side wall portion 17b on the vehicle outer side of the molding body 17. Is covered with a decorative cover member 28 formed of a metal plate or the like. The molding body 17 may be a roll-formed bent product of a metal plate or a composite extruded product of the bent product and a polymer material.

  When the outer belt molding 16 is attached to the outer door panel 14, the outer belt molding 16 is pressed from the top to the bottom, and the upper edge flange portion 15 of the outer door panel 14 is inserted into the downward mounting groove G1 of the molding body portion 17. The locking piece 17c formed at the lower end of the side wall portion 17a on the inner side of the molding body 17 is locked to the lower end of the upper edge flange portion 15. In that case, the cushion part 21 and each protrusion 23-26 contact | abut to the outer door panel 14, respectively, and are hold | maintained at the outer door panel 14 in the state by which the molding main body part 17 was positioned.

  As shown in FIGS. 3A and 3B, a wiper lip 29 is held on the wiper lip holding portion 18 provided on the side wall portion 17 a on the vehicle inner side of the molding body portion 17. The wiper lip holding portion 18 and the wiper lip 29 are formed in a long shape so as to extend over substantially the entire width of the maximum width portion (lower portion) of the window plate 13.

  The wiper lip 29 is formed by injection molding or extrusion molding of an elastic polymer material, and a tip 30 having a substantially triangular cross section that can be elastically contacted with the vehicle outer surface 13a of the window plate 13 and a base held by the wiper lip holding unit 18. An end portion 31 and a connecting portion 32 that connects the distal end portion 30 to the proximal end portion 31 are integrally formed, and a core material 33 formed of an elastic metal strip material is embedded in the proximal end portion 31 by insert molding. Has been. Note that the core material 33 may be omitted. Further, the base end portion 31 may be formed of an elastic polymer material harder than the distal end portion 30. As the elastic polymer material for forming the wiper lip 29, for example, natural rubber, chloroprene rubber, EPDM (ethylene / propylene / diene copolymer rubber), mixed rubber obtained by mixing these rubbers, thermoplastic elastomer, and the like are used.

  The connecting portion 32 of the wiper lip 29 is formed such that the thickness dimension in the moving direction of the window plate 13 is thinner than the base end portion 31 and the root portion of the distal end portion 30, and the connecting portion 32 moves the window plate 13. It is designed to bend and deform easily in the direction. Due to the bending deformation of the connecting portion 32, the swinging motion in which the distal end portion 30 tilts in the moving direction of the window plate 13 can be facilitated, and the distal end portion 30 is the outer surface (window plate outer surface) 13a of the window plate 13. Is elastically contacted at an appropriate angle (an angle suitable for wiping).

  Further, an upper edge 34 (first edge) and a lower edge 35 (second edge) are formed at the distal end of the distal end portion 30 of the wiper lip 29 so as to contact the window plate outer surface 13a. These edges 34 and 35 are formed to be sharp and continuous edges by cutting the tip of the tip 30 of the wiper lip 29. The surface of the wiper lip 29 is further treated with chlorine and graphite so as to reduce friction with the surface of the window plate 13. As shown in FIG. 3A, when the window plate 13 is lowered (when the window plate 13 moves in the opening direction), the tip portion 30 is tilted downward (elastically deformed in a state inclined downward). The upper edge 34 is in linear contact with the window plate outer surface 13a. On the other hand, as shown in FIG. 3B, when the window plate 13 is raised (when the window plate 13 moves in the closing direction), the tip 30 is tilted upward and the lower edge 35 is lined with the window plate outer surface 13a. It comes in contact with the shape.

  On the other hand, as shown in FIGS. 3A and 3B, the wiper lip holding portion 18 has an upper wall portion 37 and a lower wall portion 38 that extend substantially in parallel from the upper and lower ends of the bottom wall portion 36 toward the window plate 13 respectively. Are formed so as to sandwich the base end portion 31 of the wiper lip 29 in the vertical direction (moving direction of the window plate 13). Accordingly, the base end portion 31 of the wiper lip 29 moves in the moving direction of the window plate 13 while allowing the base end portion 31 of the wiper lip 29 to move in the direction approaching and separating from the window plate 13. The upper wall portion 37 and the lower wall portion 38 are used for blocking. Further, distal end stopper portions 39 and 40 for restricting unlimited movement of the base end portion 31 of the wiper lip 29 toward the window plate 13 are respectively connected to the distal ends of the wall portions 37 and 38 of the wiper lip holding portion 18. It is formed thinner than 32 lengths. The tips of the tip stoppers 39 and 40 are rounded so that they can be easily bent with less interference when the connecting portion 32 of the wiper lip 29 is bent. Furthermore, a plurality of foreign matter discharge holes 41 are provided in the lower wall portion 38 of the wiper lip holding portion 18 so that foreign matters such as water and mud that have entered the wiper lip holding portion 18 are discharged downward from the foreign matter discharge holes 41. It has become.

  Further, between the bottom wall portion 36 of the wiper lip holding portion 18 and the base end portion 31 of the wiper lip 29, a metal coil spring 42 (wiper lip urging means) extends over almost the entire length of the wiper lip 29. The base end portion 31 of the wiper lip 29 is urged toward the window plate 13 by the coil spring 42. As shown in FIG. 4A, the coil spring 42 is formed into a cylindrical shape by spirally winding a stainless steel wire or a metal wire subjected to rust prevention treatment. As shown in FIG. 4B, the coil spring 42 is formed in the radial direction. The base end portion 31 of the wiper lip 29 is arranged to be urged toward the window plate 13 by elastic force when a load is applied so as to be crushed and elastically deformed into a substantially elliptical cross section (see FIG. 3). Yes. The coil spring 42 is formed so that the elastically deformable amount in the radial direction (that is, the direction approaching / separating from the window plate 13) is larger than the allowable movement amount of the base end portion 31 of the wiper lip 29. The base end portion 31 of the lip 29 can be positively biased toward the window plate 13 side.

  As shown in FIG. 5A, when the outer belt molding 16 is attached to the outer door panel 14, and the distance between the molding body 17 and the window plate outer surface 13a is a normal dimension L (variation median value), the coil spring 42 is It is set so as to be elastically deformed by a predetermined amount in the radial direction by being pushed by the base end portion 31 of the wiper lip 29, and the distal end portion 30 of the wiper lip 29 is appropriately pressed by the elastic force of the coil spring 42. It comes in contact with 13a.

  Then, as shown in FIG. 5B, when the distance between the molding body 17 and the window plate outer surface 13a is a dimension L1 larger than the normal dimension L, the wiper lip 29 is correspondingly caused by the elastic force of the coil spring 42. By moving to the window plate 13 side, the positional relationship between the tip portion 30 of the wiper lip 29 and the window plate outer surface 13a is kept constant, and the tip portion 30 of the wiper lip 29 is elastically applied to the window plate outer surface 13a with an appropriate pressing force. It comes to touch.

  On the other hand, as shown in FIG. 5C, when the distance between the molding body 17 and the window plate outer surface 13a is a dimension L2 smaller than the normal dimension L, the wiper lip 29 resists the elastic force of the coil spring 42 accordingly. Then, it moves to the opposite side of the window plate 13 so that the positional relationship between the distal end portion 30 of the wiper lip 29 and the outer surface 13a of the window plate is kept constant, and the distal end portion 30 of the wiper lip 29 is pressed with an appropriate pressing force. The outer surface 13a is elastically contacted.

  In FIGS. 5A to 5C, for easy understanding, the tip portion 30 of the wiper lip 29 is illustrated in a state where the tip end portion 30 of the wiper lip 29 is not tilted. When the window plate 13 is moved, the window plate 13 is tilted in the moving direction (see FIGS. 3A and 3B), and when the window plate 13 is stopped, the window plate 13 is tilted in the moving direction of the immediately preceding window plate 13.

  When the outer belt molding 16 is attached to the outer door panel 14, the tip 30 of the wiper lip 29 elastically contacts the window plate outer surface 13a, so that the window belt 13 and the outer door panel 14 (upper edge flange 15) are in contact with each other. Is wiped with a wiper lip 29, and when the window plate 13 is opened and closed, foreign matter such as rain water and mud adhering to the outer surface 13a of the window plate is wiped off at the tip 30 of the wiper lip 29.

  When the window plate 13 is curved with the outside of the vehicle as a convex surface, the molding body 17 is curved so as to hold the entire wiper lip 29 in a direction in which the distal end 30 is concave. The outer door panel 14 (upper edge flange 15) may be attached. Thereby, even when the window plate 13 is curved with the outside of the vehicle as a convex surface, the distal end portion 30 of the wiper lip 29 is curved in a concave shape so that the entire distal end portion 30 is elastically contacted with the window plate outer surface 13a (convex surface). be able to. The molding body 17 may be formed in a curved shape in advance.

  Further, the contact lip 20 provided below the wiper lip 29 (on the opening direction side of the window plate 13) elastically contacts the window plate outer surface 13a, so that the window plate 13 and the outer door panel 14 (upper edge flange 15) are not in contact with each other. Is covered with the contact lip 20 and when the window plate 13 is opened and closed, the contact lip 20 also wipes off foreign matter such as rainwater and mud adhering to the window plate outer surface 13a. The contact lip 20 also functions as a stopper portion that prevents the window plate 13 from being excessively displaced to the outside of the vehicle due to vehicle vibration or the like, and the opening and closing of the window plate 13 is hindered by the excessive displacement of the window plate 13. It is possible to prevent the wiper lip 29 from being damaged. In this case, even if a wiping residue is generated at the contact lip 20, the wiping residue can be wiped off by the wiper lip 29 provided in the closing direction (upper side) of the window plate 13. Closed and good visibility can be maintained.

  Further, the shielding lip 19 provided above the wiper lip 29 (on the closing direction side of the window plate 13) prevents foreign matters from entering between the outer belt molding 16 and the window plate 13 from above. It has become. Further, the wiper lip 29 can be concealed by the shielding lip 19, and the decorativeness is prevented from deteriorating.

  In the first embodiment described above, the base end portion 31 of the wiper lip 29 is held by the wiper lip holding portion 18 so as to be movable toward and away from the window plate 13 and is moved toward the window plate 13 by the coil spring 42. Therefore, even if the positional relationship between the outer belt molding 16 and the window plate 13 fluctuates, the wiper lip 29 moves correspondingly and the positional relationship between the wiper lip 29 and the window plate 13 is substantially constant. The tip 30 of the wiper lip 29 can always be brought into elastic contact with the window plate outer surface 13a with an appropriate pressing force. As a result, the positional relationship between the outer belt molding 16 and the window plate 13 varies due to individual differences of each vehicle and each window (part dimensional variations, assembly errors, etc.), or when the window plate 13 is opened and closed. Even if the positional relationship between the outer belt molding 16 and the window plate 13 fluctuates depending on the movement position (movement locus) of the window plate 13, the tip 30 of the wiper lip 29 is always continuously pushed over the entire length and properly pressed. It can be elastically brought into contact with the window plate outer surface 13a by pressure, and a good wiping performance for the window plate outer surface 13a can be stably secured.

  In the first embodiment, since the edges 34 and 35 that contact the window plate outer surface 13a are formed at the tip 30 of the wiper lip 29, the edges 34 and 35 of the tip 30 of the wiper lip 29 are formed in the window. The tip 30 (edges 34, 35) of the wiper lip 29 and the window plate outer surface 13a can be brought into contact with the outer surface 13a in a linear manner without gaps, and the wiper lip 29 is wiped from the surface of the window plate 13. Performance can be improved.

  Moreover, in the first embodiment, when the window plate 13 is lowered (when the window plate 13 moves in the opening direction), the tip portion 30 tilts downward and the upper edge 34 is linearly formed on the window plate outer surface 13a. When the window plate 13 rises (when the window plate 13 moves in the closing direction), the tip 30 is tilted upward so that the lower edge 35 comes into linear contact with the window plate outer surface 13a. Therefore, every time the moving direction of the window plate 13 is reversed, the edge contacting the window plate outer surface 13a can be switched, and the amount of wear of each edge 34, 35 can be reduced to maintain good wiping performance for a long period of time. Can do.

  In the first embodiment, since the wiper lip 29 is provided over almost the entire width of the maximum width portion (lower portion) of the window plate 13, the distal end portion 30 of the wiper lip 29 is substantially the same as that of the window plate 13. Elastic contact can be achieved over the entire width, and almost the entire width of the window plate outer surface 13a can be wiped and cleaned by the tip 30 of the wiper lip 29.

  In the first embodiment, since the metal coil spring 42 (elastic body) is used as the wiper lip urging means for urging the base end portion 31 of the wiper lip 29, the coil spring 42 is elastically deformed. The base end portion 31 of the wiper lip 29 can be urged by the elastic force generated at the time, and no additional energy or the like is required. In addition, the base end portion 31 of the wiper lip 29 can be urged with a stable pressing force even under a high or low temperature environment.

  Furthermore, in the first embodiment, since the base end portion 31 of the wiper lip 29 is urged by utilizing the elastic force of the coil spring 42 in the radial direction, the long range of the long coil spring 42 is long. Thus, the base end portion 31 of the wiper lip 29 can be urged.
