Description

  The present invention relates to a glass run channel assembly that is mounted along a window frame of a vehicle and guides sliding movement of the window glass.

  In general, the window frame structure of an automobile is mounted with a long glass run channel along the inner periphery of the door window frame, for example, as described in Patent Document 1 (Japanese Patent Laid-Open No. 2002-301936). The glass run channel guides the window glass to move up and down (slide movement). The glass run channel includes a base portion opposed to the end face of the window glass, side walls on the vehicle inner side and vehicle outer side formed from both ends in the width direction of the base portion toward the window glass side, and A vehicle interior and exterior seal lip formed from the front end side toward the center in the width direction of the base portion, and holding the window glass by bringing each seal lip into contact with the surface of the window glass. There is one that seals between the window frame and the window glass.

For example, as shown in FIG. 5, the window frame 2 of the front door 1 of a general automobile has two parallel window frame portions 4 and 5 parallel to the up-and-down movement direction of the window glass 3, and the inclination of the front pillar. Corresponding inclined window frame part 6 and upper window frame part 7 extending in a substantially horizontal direction corresponding to the roof are formed, and a long glass run channel 8 is formed along the inner peripheral edge of window frame 2. It is installed. Thus, in the window frame structure having the inclined window frame portion 6, the glass run channel in which the front end portion 3a and the rear end portion 3b of the window glass 3 are always attached to the parallel window frame portion 4 and the parallel window frame portion 5, respectively. 8 when the window glass 3 is raised to the uppermost position (fully closed position), the inclined portion 3c and the upper end portion 3d of the window glass 3 are inclined window frame portion 6 and upper window frame portion, respectively. 7 is held by a seal lip of the glass run channel 8 attached to the unit 7.
JP 2002-301936 A (2nd page, FIG. 1 etc.)

  However, as shown in FIG. 5, in the window frame structure having the inclined window frame portion 6, when the window glass 3 is in a half-open state, the inclined portion 3 c and the upper end portion 3 d of the window glass 3 are respectively inclined window frame portions 6. And the upper window frame portion 7 away from the center of the opening of the window frame 2 and disengaged from the seal lip of the glass run channel 8 attached to the inclined window frame portion 6 and the upper window frame portion 7. The portion 3c and the upper end portion 3d are not held by the glass run channel 8. For this reason, when the inclined window frame portion 6 has a relatively long window frame structure like the door 1 of a truck or the like, the inclined window glass 3 is not held by the glass run channel 8 when the window glass 3 is in a half-open state. Since the portion 3c becomes long, the window glass 3 may be displaced in the groove width direction of the glass run channel 8 due to vibration of the vehicle or the like, and unpleasant noise may be generated due to vibration.

  The present invention has been made in view of such circumstances. Accordingly, the object of the present invention is to reduce or prevent window glass misalignment and vibration due to vehicle vibration even when the window glass is in a half-open state. It is an object of the present invention to provide a glass run channel assembly.

  In order to achieve the above object, a glass run channel assembly according to claim 1 of the present invention includes a parallel window frame portion that is substantially parallel to a moving direction of a window glass that slides within a window frame of a vehicle, and the window glass. A long glass run channel assembly made of a polymer material, which is mounted along a window frame having an inclined window frame portion inclined with respect to the moving direction, and is configured to guide the sliding movement of the window glass A long first member that is continuously attached along at least the parallel window frame portion and the inclined window frame portion, and an inclined window frame that is integrally provided at least on the vehicle exterior side of the first member. A substantially plate-like second member protruding beyond the first member toward the center of the opening of the window frame at a position corresponding to the portion, and the first member has at least a base portion facing the end surface of the window glass And stand from both ends of the base in the width direction. Vehicle interior and vehicle exterior side walls extending so as to rise, and vehicle interior and vehicle exterior seal lips that protrude from the front end side of each sidewall portion toward the center in the width direction of the base portion and can contact the window glass. The provided second member is provided with a misregistration restricting portion for regulating the misalignment of the window glass to at least the vehicle outer side at the center side of the opening of the window frame relative to the seal lip of the first member.

  If it does in this way, a window glass will be in a half-opened state, the inclination part of a window glass will leave | separate from the inclination window frame part to the opening-part center side of a window frame, and the 1st member with which the inclination window frame part was mounted | worn Even when it deviates from the seal lip, the positional deviation of the window glass to at least the outside of the vehicle can be regulated by the positional deviation regulating portion of the second member protruding beyond the first member toward the center of the opening of the window frame. . Thereby, even when the window glass is in a half-opened state, positional deviation and vibration of the window glass due to vehicle vibration or the like can be reduced or prevented.

  In this case, when the window glass is fully closed, the gap between the inclined window frame portion and the window glass can be sealed by the seal lip of the first member attached to the inclined window frame portion. It is not necessary to have a sealing function. That is, it is not always necessary to bring the position deviation restricting portion of the second member into contact with the window glass surface.

  Therefore, as described in claim 2, the position deviation restricting portion of the second member is provided so that a slight gap is formed between the glass run channel assembly and the window glass surface when the glass run channel assembly is mounted on the window frame. You may do it. In this way, when the window glass is opened / closed, no sliding resistance is generated between the position shift restricting portion and the window glass surface, so that the window glass opening / closing operation force (power window motor load) is quite large. Therefore, it is possible to provide a function for preventing the window glass from shifting without impairing the opening / closing performance of the window glass.

  Alternatively, as described in claim 3, the position deviation restricting portion of the second member is greater than the force with which the seal lip of the first member contacts the window glass surface when the glass run channel assembly is mounted on the window frame. You may make it provide so that it may contact with the window glass surface with weak force. In this way, when the window glass is opened / closed, the sliding resistance generated between the position deviation restricting portion and the window glass surface can be reduced, so that the window glass opening / closing operation force (power window motor load) Can be prevented from becoming too large, and the function of preventing the window glass from shifting can be provided without significantly reducing the opening / closing performance of the window glass.

  Further, a low friction material layer having a smaller friction coefficient than that of the second member may be formed on the surface of the position deviation restricting portion of the second member. In this way, even if the position deviation restricting portion comes into contact with the window glass surface, it is possible to prevent the sliding resistance generated between the position deviation restricting portion and the window glass surface from excessively increasing. it can.

  By the way, the distance from the inclined window frame portion to the inclined portion of the window glass becomes longer as the window glass moves in the opening direction. In consideration of this point, it is preferable that the second member is formed in a substantially triangular shape whose width is increased in the opening direction of the window glass. In this way, the more the window glass moves in the opening direction, the longer the distance from the inclined window frame part to the inclined part of the window glass, the wider the width of the second member, and the inclined window. The distance from the frame part to the position deviation regulating part can be increased, and the position deviation of the window glass can be reduced or prevented in a wide range of the half-open position of the window glass.

  In this case, the range of the half-open position of the window glass that can prevent the window glass from being displaced can be increased as the width of the second member is increased to increase the distance from the inclined window frame part to the position deviation restricting part. it can. However, if the width dimension of the second member is too large, the amount of protrusion of the second member toward the center of the opening of the window frame increases, and the window opening area is reduced accordingly.

  Therefore, as in claim 6, the second member is preferably formed such that the edge of the window frame facing the center of the opening portion extends substantially parallel to the moving direction of the window glass. In this way, the window glass moves in the opening direction while ensuring both the width of the second member (the amount of protrusion of the second member toward the center of the opening of the window frame) and the area of the window opening. The larger the width of the second member is, the longer the distance from the inclined window frame portion to the misregistration restricting portion is, so that the range of the half-open position of the window glass that can prevent the misalignment of the window glass is widened. can do.

  Moreover, you may make it integrally form the some reinforcement rib extended in the direction which cross | intersects the moving direction of a window glass in the back surface of the 2nd member like Claim 7. If it does in this way, the 2nd member can be reinforced with a reinforcement rib, and the position shift prevention effect of the window glass by the 2nd member can be heightened.

  Further, as in claim 8, the second member may be integrally provided on both the vehicle inner side and the vehicle outer side of the first member. If it does in this way, since the position shift of a window glass can be controlled by the position shift control part from both the vehicle inside and the vehicle outside of the 1st member, the position shift of a window glass can be prevented more certainly. .

  According to a ninth aspect of the present invention, the first member may be formed in an elongated shape by extrusion molding, and the second member may be formed by injection molding and integrally joined to a predetermined portion of the first member. Thus, if the second member is injection-molded, unlike the case where it is extrusion-molded, it is not necessary to mold the second member into a constant cross-sectional shape. For this reason, there is an advantage that the degree of freedom of the shape of the second member can be made larger than that of extrusion molding, and the shape of the second member can be easily designed into a shape that places importance on the functional surface, the design surface and the like. In addition, since the first member and the second member can be joined simultaneously with the injection molding of the second member, the productivity can also be improved.

  Furthermore, when the shielding lip which covers the inner periphery of the window frame along the longitudinal direction of the first member is integrally provided as in the tenth aspect, the first of the shielding lips of the first member. The portion where the two members are provided is removed along the longitudinal direction, and the shielding lip of the second member is formed in the portion where the shielding lip of the first member is removed, thereby shielding the shielding lip of the first member and the second member. You may make it join a lip so that it may continue in a longitudinal direction. In this way, it is possible to ensure a wide bonding area between the first member and the second member, increase the bonding strength between the first member and the second member, and to increase the bonding strength between the first member and the second member. The two-member shielding lip can be formed continuously, and the first member and the second member can be integrated with good appearance.

  Further, as in claim 11, the first member is formed of vulcanized rubber, the second member is formed of vulcanized rubber or olefinic thermoplastic elastomer, and the first member and the second member are They may be integrated by vulcanization or fusion bonding. When both the first member and the second member are formed of vulcanized rubber, for example, the first member formed and vulcanized by extrusion molding of unvulcanized rubber is set in the injection mold of the second member. In this state, the unvulcanized rubber is injected into a heatable injection mold to form and vulcanize the second member, and in the vulcanization process by heating the second member, the second member becomes the first member. It can be firmly joined by vulcanization joining. Further, when the first member is formed of vulcanized rubber and the second member is formed of olefinic thermoplastic elastomer, for example, the first member formed and vulcanized by extrusion molding of unvulcanized rubber is used. The second member is formed by injecting the heat-melted olefin-based thermoplastic elastomer into the injection mold in a state where the second member is set in the injection mold of the second member, and the olefin component in the rubber of the first member and the first The olefin component in the two-membered olefinic thermoplastic elastomer can be firmly bonded by fusion.

  Further, as in the twelfth aspect, both the first member and the second member may be formed of an olefin thermoplastic elastomer, and the two members may be integrated by fusion bonding. In this case, for example, the first member formed by extrusion molding of the olefinic thermoplastic elastomer is set in the injection molding die of the second member, and the olefinic thermoplastic elastomer heated and melted is injected into the injection molding die. Thus, the second member can be formed, and the first member and the second member can be firmly bonded to each other by fusion of the olefinic thermoplastic elastomers, and a stable bonding strength can be obtained.

  Hereinafter, an embodiment in which the present invention is applied to a glass run channel assembly mounted on a window frame of a truck door will be described with reference to FIGS.

  First, a schematic configuration of the entire door 11 will be described with reference to FIG. A window frame 12 is integrally provided on the door 11, and a long glass run channel assembly 13 made of an elastic polymer material is attached to the window frame 12 along the window frame 12. The assembly 13 guides the window glass 14 to move up and down (slide movement). A belt molding 46 that guides the window glass 14 to move up and down is attached to the lower edge of the opening of the window frame 12.

  The window frame 12 includes two front and rear parallel window frame portions 15 and 16 substantially parallel to the moving direction of the window glass 14, and an inclined window frame portion 17 inclined in accordance with the inclination of the front pillar, The upper window frame portion 18 extends substantially in the horizontal direction corresponding to the roof.

  Further, the glass run channel assembly 13 includes a long front side glass run channel 19 (first number) that is continuously mounted along the front parallel window frame portion 15, the inclined window frame portion 17, and the upper window frame portion 18. 1 member), a long rear glass run channel 20 mounted along the parallel window frame 16 on the rear side, a corner for joining the front glass run channel 19 and the rear glass run channel 20 to each other. The glass run channel 21 and sub glass run channels 22 and 23 (second members) integrally joined to both the vehicle inner side and the vehicle outer side of the front side glass run channel 19 are configured. Each of the sub glass run channels 22 and 23 is provided in a portion of the front side glass run channel 19 that is attached to the lower end portion of the inclined window frame portion 17 or in the vicinity thereof.

  The elastic polymer material for forming the front side glass run channel 19, the rear side glass run channel 20, and the corner glass run channel 21 is, for example, a thermoplastic elastomer such as TPO (olefin-based thermoplastic elastomer) or an EPDM containing an olefin component ( A rubber such as ethylene-propylene-diene copolymer rubber) is used, and the front side glass run channel 19 and the rear side glass run channel 20 are each formed in a straight line during molding by extrusion molding or the like. Further, the corner glass run channel 21 is formed in a curved shape according to the shape of the corner portion of the window frame 12 by injection molding or the like.

  In this case, the injection molding is performed in a state where the rear end portion of the front side glass run channel 19 and the upper end portion of the rear side glass run channel 20 are set to intersect at a predetermined angle in the injection mold of the corner glass run channel 21. By injecting an elastic polymer material into the mold to form the corner glass run channel 21, the front side glass run channel 19 and the rear side glass run channel 20 are joined via the corner glass run channel 21.

  The elastic polymer material for molding the sub glass run channels 22 and 23 is, for example, a thermoplastic elastomer such as TPO or rubber such as EPDM containing an olefin component, and the sub glass run channels 22 and 23 are formed by injection molding or the like. Is formed in a substantially plate shape.

  The combination of the elastic polymer material forming the front side glass run channel 19 and the sub glass run channels 22 and 23 is, for example, the front side glass run channel 19 in order to secure the bonding strength when both are bonded by the method described later. Is formed by TPO, the sub-glass run channels 22 and 23 are preferably formed by TPO. Further, when the front side glass run channel 19 is formed of vulcanized rubber (vulcanized rubber), the sub glass run channels 22 and 23 are preferably formed of vulcanized rubber or TPO.

  Next, the configuration of the front side glass run channel 19 will be described with reference to FIG. The front side glass run channel 19 includes a base portion 24 facing the end face of the window glass 14, a vehicle inner side wall portion 25 and a vehicle outer side wall portion 26 extending so as to rise from both ends in the width direction of the base portion 24. The inner side seal lip 27 and the outer side seal lip 28 which are formed in a folded shape so as to protrude from the front end sides of the side wall portions 25 and 26 toward the substantially central side in the width direction of the base portion 24, respectively, A shielding lip 29 on the inside of the vehicle and a shielding lip 30 on the outside of the vehicle, which are formed in a folded shape so as to protrude from the front end sides of 25 and 26 toward the opposite sides of the seal lips 27 and 28, are integrally formed.

  When the front side glass run channel 19 is mounted on the window frame 12, the inner rim 31 on the inner side of the car frame and the inner peripheral edge 31 on the outer side of the car frame, respectively, 32 is concealed. Further, the seal lip 27 on the inside of the vehicle and the seal lip 28 on the outside of the vehicle are in contact with the surface of the window glass 14 so as to hold the window glass 14 and seal between the window frame 12 and the window glass 14. It has become.

  Further, low friction material layers 33 and 34 are formed on the surfaces of the seal lips 27 and 28 (surfaces on the window glass 14 side) with a thickness of 0.02 to 3 mm, for example. The low-friction material layers 33 and 34 are formed of a low-friction material whose friction coefficient with respect to the surface of the window glass 14 is smaller than that of the main body of the seal lips 27 and 28, and the seal lips 27 and 28 and the window glass when the window glass 14 moves. 14 plays a role in reducing the sliding resistance generated between the two. The seal lips 27 and 28 and the low friction material layers 33 and 34 are fused and integrated by coextrusion molding.

  When the seal lips 27 and 28 are made of a thermoplastic elastomer such as TPO, the low friction material forming the low friction material layers 33 and 34 is compatible with, for example, the material forming the seal lips 27 and 28. Thermoplastic elastomer, which has a higher resin component ratio than seal lips 27 and 28 (that is, a lower rubber component ratio), and a lubricant material (for example, silicone oil, fluororesin fine powder, silicone resin) A thermoplastic elastomer kneaded with fine powder, high molecular weight polyethylene or the like is used. The low friction material layers 33 and 34 may be formed by bonding low friction films on the surfaces of the seal lips 27 and 28 after extrusion molding. When the seal lips 27 and 28 are made of vulcanized rubber, the low friction material layers 33 and 34 may be formed by applying urethane paint or the like on the surfaces of the seal lips 27 and 28.

  Also, the low friction material layer 35 may be formed on the surface of the base portion 24 (the surface on the window glass 14 side). Further, at least one of the inner surfaces (surfaces on the seal lips 27 and 28 side) of the side walls 25 and 26 and the back surfaces (surfaces on the side of the side walls 25 and 26) of the seal lips 27 and 28 is non-adhesive and low friction. The material layers 36 and 37 may be formed to prevent the generation of the separation sound caused by the separation after the seal lips 27 and 28 are attached to the side wall portions 25 and 26.

  Next, the configuration of the sub glass run channels 22 and 23 that are integrally joined to both the inside and the outside of the front side glass run channel 19 will be described with reference to FIGS. 3 and 4. As shown in FIG. 3, each of the sub glass run channels 22 and 23 is provided in a portion of the front side glass run channel 19 that is attached to the lower end portion of the inclined window frame portion 17 or in the vicinity thereof, and the window frame 12. It is formed in a substantially plate shape that protrudes beyond the front side glass run channel 19 toward the center of the opening.

  Each of the sub glass run channels 22 and 23 is formed in a substantially triangular shape whose width is increased toward the opening direction of the window glass 14. Accordingly, as the window glass 14 moves in the opening direction, the distance from the inclined window frame portion 17 to the inclined portion 14c of the window glass 14 (see FIG. 1) becomes longer. , 23 is made wider. In this case, if the width dimension of each of the sub glass run channels 22 and 23 is excessively widened, the amount of projection of each sub glass run channel 22 and 23 toward the center of the opening of the window frame 12 increases. Since the opening area becomes small, each of the sub glass run channels 22 and 23 has an edge portion (tip portions of position shift restricting portions 38 and 39 described later) facing the center of the opening portion of the window frame 12. It is formed so as to extend substantially parallel to the moving direction. Thus, both the securing of the width dimension of each of the sub glass run channels 22 and 23 (the amount of protrusion of each sub glass run channel 22 and 23 toward the center of the opening of the window frame 12) and the securing of the window opening area are achieved. I have to.

  As shown in FIG. 4, each sub glass run channel 22, 23 is joined to the front side glass run channel 19 at the front end side cut surface of each side wall portion 25, 26 of the front side glass run channel 19, and from there Projection bases 51 and 52 projecting toward the opposite side of the seal lips 27 and 28, vehicle interior and exterior shielding lips 42 and 43 formed in a folded shape from the projection bases 51 and 52, and projection bases, respectively. 51, 52 projecting walls 53, 54 projecting toward the center of the opening of the window frame 12, respectively, and positions on the vehicle inner side and the vehicle outer side extending obliquely from the tips of the projecting walls 53, 54 toward the window glass 14, respectively. The shift restricting portions 38 and 39 are integrally formed.

  The front side of each sub glass run channel 22, 23 is closer to the front side of the center of the opening of the window frame 12 than the seal lips 27, 28 of the front side glass run channel 19. A position deviation restricting portion 38 on the inside of the vehicle and a position displacement restricting portion 39 on the outside of the vehicle are integrally formed so as to protrude toward the center side in the width direction of the glass run channel 19. When each of the sub glass run channels 22 and 23 is mounted on the window frame 12, the position deviation restricting portion 38 on the vehicle inner side and the position deviation restricting portion 39 on the outside of the vehicle are respectively displaced from the window glass 14 toward the inside of the vehicle. And the position shift to the outside of the car is regulated.

  When the sub-glass run channels 22 and 23 are mounted on the window frame 12, the position shift restricting portions 38 and 39 are slightly spaced from the surface of the window glass 14 (for example, a gap of 0.1 to 5 mm). (Preferably a gap of 0.5 to 2 mm) is formed so that sliding resistance does not occur between the position shift restricting portions 38 and 39 and the surface of the window glass 14 when the window glass 14 is opened and closed. ing.

  Furthermore, low friction material layers 40 and 41 are formed on the surfaces of the respective displacement control portions 38 and 39 with a thickness of several μm to several tens of μm, for example. The low friction material layers 40 and 41 are formed of a low friction material whose friction coefficient with respect to the surface of the window glass 14 is smaller than that of the main body of the position deviation restricting portions 38 and 39, and the position deviation restricting portions 38 and 39 are in contact with the surface of the window glass 14. Even in such a state, it plays a role of preventing the sliding resistance generated between the position shift restricting portions 38 and 39 and the window glass 14 from excessively increasing. The low-friction material layers 40 and 41 are formed by coating the surface of the misregistration restricting portions 38 and 39 with a low-friction material such as a liquid urethane resin lubricant, for example. In FIG. 4, the thickness of the low friction material layers 40 and 41 is shown exaggerated larger than the actual thickness. Instead of the above configuration or in addition to the above configuration, the surface of the positional deviation restricting portions 38 and 39 may be roughened, or a plurality of ridges may be formed. Can be prevented or more effectively prevented.

  On the other hand, on the base side of each of the sub glass run channels 22 and 23, a shielding lip 42 on the inside of the vehicle that protrudes toward the opposite side of the seal lips 27 and 28 of the front side glass run channel 19 and is folded back. A shielding lip 43 on the outside of the vehicle is integrally formed. When each sub glass run channel 22, 23 is mounted on the window frame 12, a shielding lip 42 on the inside of the vehicle and a shielding lip 43 on the outside of the vehicle are respectively connected to the inner peripheral edge 31 on the inside of the vehicle on the inside of the window frame 12 and on the outside of the vehicle. The inner peripheral edge 32 is obscured.

  A plurality of reinforcing ribs 44 a, 44 b, 45 a, 45 b extending in the direction intersecting the moving direction of the window glass 14 are maintained at predetermined intervals on the back surfaces (surfaces on the window glass 14 side) of the sub glass run channels 22, 23. Is formed. That is, reinforcing ribs 45a and 45b are provided on the back surface of the projecting wall 54 and the shielding lip 43 in the sub glass run channel 23 on the outside of the vehicle, and reinforcing ribs 44a are provided on the back surface of the projecting wall 53 in the sub glass run channel 22 on the inside of the vehicle. A reinforcing rib 44b is formed on the outside of the side wall 25 on the vehicle inner side of the front side glass run channel 19 at the same time as the sub glass run channels 22 and 23 are formed. Further, as shown in FIG. 3, the lower end portions of the sub glass run channels 22 and 23 are formed in a bent shape in accordance with the shape of the corner portion of the window frame 12, and when attached to the window frame 12, The side end surfaces of the lower end portions of the sub glass run channels 22 and 23 are abutted against and connected to the end surface of the belt molding 46.

  The front glass run channel 19 and the sub glass run channels 22 and 23 are joined as follows. The front side glass run channel 19 is a portion where the sub glass run channels 22 and 23 are provided in the shielding lips 29 and 30 integrally formed along the longitudinal direction (at the lower end portion of the inclined window frame portion 17 or in the vicinity thereof). The portion from the attached portion to the portion attached to the parallel window frame portion 15) is cut and removed at the boundary portions with the side wall portions 25 and 26.

  Then, the sub glass run channels 22 and 23 are formed by injection molding at the portion where the shielding lips 29 and 30 of the front side glass run channel 19 are cut and removed, as shown in FIG. Sub-glass run channels 22 and 23 are joined to the front end portions of 19 side wall portions 25 and 26 (the cut surface from which the shielding lips 29 and 30 are cut and removed and the periphery thereof), as shown in FIG. Further, the upper ends of the shielding lips 42 and 43 of the sub glass run channels 22 and 23 are joined to the cut surfaces of the shielding lips 29 and 30 of the front side glass run channel 19 so as to be continuous in the longitudinal direction.

  When both the front glass run channel 19 and the sub glass run channels 22 and 23 are formed by TPO, the straight front glass run channel 19 formed by TPO extrusion molding corresponds to the bent shape of the window frame 12. The sub glass run channels 22 and 23 are formed by injecting TPO that has been heated and melted into the injection mold in a state where the sub glass run channels 22 and 23 are set in the injection mold of the sub glass run channels 22 and 23. Thereby, the front side glass run channel 19 and the sub glass run channels 22 and 23 can be firmly joined by fusion of TPOs (fusion by the heat and pressure of molten TPO injected into the mold). Stable bonding strength can be obtained.

  Further, when both the front side glass run channel 19 and the sub glass run channels 22 and 23 are formed of vulcanized rubber, vulcanization (hereinafter referred to as “molding / vulcanization”) is performed by extrusion molding of unvulcanized rubber. In a state where the straight front side glass run channel 19 which is abbreviated) is set in the injection mold of the sub glass run channels 22 and 23, unvulcanized rubber is injected into the heatable injection mold and the sub glass run Channels 22 and 23 are formed and vulcanized. Accordingly, the sub glass run channels 22 and 23 can be firmly bonded to the front side glass run channel 19 by vulcanization in the vulcanization process by heating the sub glass run channels 22 and 23.

  When the front side glass run channel 19 is formed of vulcanized rubber and the sub glass run channels 22 and 23 are formed of TPO, the front side glass run channel formed and vulcanized by extrusion molding of unvulcanized rubber. In a state where 19 is set in the injection mold of the sub glass run channels 22 and 23, TPO heated and melted is injected into the injection mold to form the sub glass run channels 22 and 23. Thereby, the olefin component in the rubber of the front side glass run channel 19 and the olefin component in the TPO of the sub-glass run channels 22 and 23 can be firmly bonded by fusion.

  As shown in FIG. 1, in the window frame structure having the inclined window frame portion 17, the front end portion glass and the rear end portion 14 b of the window glass 14 are always attached to the front parallel window frame portion 15. The run channel 19 and the rear side glass run channel 20 mounted on the rear parallel window frame 16 are held. When the window glass 14 is raised to the uppermost position (fully closed position), the inclined portion 14c and the upper end portion 14d of the window glass 14 are mounted on the inclined window frame portion 17 and the upper window frame portion 18, respectively. It is sealed and held by the partial glass run channel 19 (see the two-dot chain line in FIG. 4).

  However, when the window glass 14 is in a half-open state, the inclined portion 14c and the upper end portion 4d of the window glass 14 are separated from the inclined window frame portion 17 and the upper window frame portion 18 toward the center of the opening of the window frame 12, respectively. Since the inclined portion 14c and the upper end portion 14d of the window glass 14 are detached from the seal lips 27, 28 of the front side glass run channel 19 mounted on the inclined window frame portion 17 and the upper window frame portion 18, the inclined portion 14c of the window glass 14 is removed. The upper end portion 14d is not held by the seal lips 27 and 28 of the front side glass run channel 19 (see the solid line in FIG. 4).

  In consideration of such circumstances, in this embodiment, both the vehicle interior side and the vehicle exterior side of the predetermined portion of the front side glass run channel 19 (the lower end portion of the inclined window frame portion 17 or a portion mounted in the vicinity thereof). Sub-glass run channels 22 and 23 projecting beyond the front glass run channel 19 toward the center of the opening of the window frame 12 are provided, and the seal of the front glass run channel 19 is provided on each sub-glass run channel 22 and 23. Since the position shift restricting portions 38 and 39 for restricting the position shift of the window glass 14 are provided closer to the center of the opening of the window frame 12 than the lips 27 and 28, the window glass 14 is in a half-open state, and the window glass is opened. Even when the 14 inclined portions 14c are disengaged from the seal lips 27 and 28 of the front side glass run channel 19, the sub glass run channels 22 and 2 on the inside and outside of the vehicle are provided. The positional displacement restricting portions 38, 39 of it is possible to restrict the positional deviation of the window glass 14 from both sides of the vehicle interior side and the exterior. Thereby, even when the window glass 14 is in a half-opened state, positional deviation and vibration of the window glass 14 due to vibration of the vehicle or the like can be effectively reduced or prevented.

  In this case, when the window glass 14 is fully closed, the gap between the inclined window frame portion 15 and the window glass 14 can be sealed by the seal lips 27 and 28 of the front side glass run channel 19 attached to the inclined window frame portion 17. Therefore, the sub glass run channels 22 and 23 do not necessarily have to have a sealing function. That is, it is not always necessary to bring the position deviation regulating portions 38 and 39 of the sub glass run channels 22 and 23 into contact with the surface of the window glass 14.

  Focusing on this point, in the present embodiment, since a slight gap is formed between the position shift restricting portions 38, 39 and the surface of the window glass 14 in the mounted state, when the window glass 14 is opened and closed, There is no sliding resistance between the position shift restricting portions 38 and 39 and the surface of the window glass 14. For this reason, the opening / closing operation force of the window glass 14 (the load of the motor of the power window) is not increased at all, and the function of preventing the window glass 14 from being displaced can be provided without impairing the opening / closing performance of the window glass 14 at all. .

  Furthermore, in the present embodiment, since the low friction material layers 40 and 41 are formed on the surfaces of the positional deviation regulating portions 38 and 39, the positional deviation regulating portions 38 and 39 are in contact with the surface of the window glass 14. Even if it becomes, it can prevent that the sliding resistance which arises between the position shift control parts 38 and 39 and the window glass 14 surface increases too much.

  By the way, the distance from the inclined window frame part 17 to the inclined part 14c of the window glass 14 becomes longer as the window glass 14 moves in the opening direction. In consideration of this point, in the present embodiment, the sub glass run channels 22 and 23 are formed in a substantially triangular shape whose width is widened in the opening direction of the window glass 14. As the distance from the inclined window frame portion 17 to the inclined portion 14c of the window glass 14 increases, the width of the sub glass run channels 22 and 23 is increased to move the inclined window frame portion 17 toward the inclined window frame portion. It is possible to increase the distance from 17 to the position deviation regulating portions 38 and 39, and to reduce or prevent the position deviation of the window glass 14 in a wide range of the half-open position of the window glass 14.

  In this case, the window glass 14 that can prevent the positional deviation of the window glass 14 is increased as the width of the sub glass run channels 22 and 23 is increased and the distance from the inclined window frame part 17 to the positional deviation regulating parts 38 and 39 is increased. Can be widened. However, if the width dimensions of the sub glass run channels 22 and 23 are too large, the amount of projection of the sub glass run channels 22 and 23 toward the center of the opening of the window frame 12 increases, and the window opening area is accordingly increased. It gets smaller.

  Therefore, in this embodiment, the sub glass run channels 22 and 23 are formed so that the edge portion facing the opening center side of the window frame 12 extends substantially parallel to the moving direction of the window glass 14. The window glass 14 opens while ensuring the width dimension of the glass run channels 22 and 23 (the amount of protrusion of the sub glass run channels 22 and 23 toward the center of the opening of the window frame 12) and the window opening area. As the position is moved in the direction, the width dimension of the sub glass run channels 22 and 23 can be increased to increase the distance from the inclined window frame portion 17 to the position deviation restricting portions 38 and 39, and the position deviation of the window glass 14 can be achieved. This can widen the range of the half-open position of the window glass 14 that can prevent the above.

  Furthermore, in this embodiment, since the plurality of reinforcing ribs 44 and 45 are provided on the back surfaces of the sub glass run channels 22 and 23, the sub glass run channels 22 and 23 are reinforced by the reinforcing ribs 44 and 45. Thus, the effect of preventing the window glass 14 from being displaced by the sub-glass run channels 22 and 23 can be enhanced.

  Further, in this embodiment, the sub glass run channels 22 and 23 are formed by injection molding and integrally joined to a predetermined portion of the front side glass run channel 19, so that the sub glass run channels 22 and 23 are extruded. Unlike the case of forming, there is no restriction on forming the sub-glass run channels 22 and 23 into a constant cross-sectional shape. For this reason, the degree of freedom of the shape of the sub glass run channels 22 and 23 can be made larger than the case of extrusion molding, and the shape of the sub glass run channels 22 and 23 is made a shape that places importance on the functional aspect, the design aspect, etc. There is an advantage that it is easy to design. Moreover, since the front glass run channel 19 and the sub glass run channels 22 and 23 can be joined simultaneously with the injection molding of the sub glass run channels 22 and 23, the productivity can be improved.

  Further, in this embodiment, the shielding lips 29, 30 of the front glass run channel 19 and the shielding lips 42, 43 of the sub glass run channels 22, 23 are joined so as to be continuous in the longitudinal direction. It is possible to secure a wide bonding area between the partial glass run channel 19 and the sub glass run channels 22 and 23 and increase the bonding strength between the front glass run channel 19 and the sub glass run channels 22 and 23. In addition, the shielding lips 29 and 30 of the front glass run channel 19 and the shielding lips 42 and 43 of the sub glass run channels 22 and 23 can be continuously formed without a step, and the front glass run channel 19 and the sub glass can be formed. It can be integrated with the run channel 22 with good appearance.

  In the above-described embodiment, a slight gap is formed between the position deviation restricting portions 38 and 39 and the surface of the window glass 14, but the position deviation restricting portions 38 and 39 are formed on the front side glass run channel 19. The seal lips 27 and 28 may contact the surface of the window glass 14 with a weaker force than the force of contacting the surface of the window glass 14. Even in this case, when the window glass 14 is opened and closed, the sliding resistance generated between the position shift restricting portions 38 and 39 and the surface of the window glass 14 can be reduced. The load of the window motor 14 can be prevented from becoming too large, and the window glass 14 can be provided with a function of preventing the position shift without deteriorating the opening / closing performance of the window glass 14 so much.

  In the above embodiment, the front glass run channel 19 and the sub glass run channels 22 and 23 are joined simultaneously with the injection molding of the sub glass run channels 22 and 23. The glass run channels 22 and 23 may be joined and integrated to the front side glass run channel 19 by bonding or the like.

  In the above embodiment, the sub glass run channels 22 and 23 are provided on both the vehicle inner side and the vehicle outer side of the front side glass run channel 19, but the vehicle inner side and the vehicle outer side of the front side glass run channel 19 are provided. Only one of them may be provided with a sub-glass run channel.

  In addition, the scope of application of the present invention is not limited to a glass run channel assembly mounted on a window frame of a truck door, but mounted on a window frame of a door that can be opened and closed such as a front door and a rear door of a general passenger car.
