  In order to obtain a reliable waterproof effect by the seal member, the seal member needs to abut against both the door frame and the window glass with an appropriate contact pressure. If the components constituting the door frame have variations in accuracy, an appropriate contact pressure of the seal member cannot be obtained, and the water tightness may be lowered. As countermeasures, a plurality of seal members are arranged in the middle of the water intrusion path, or a large seal member having a large contact area with the water stop target is used. For example, in Patent Document 1, the inner weather strip is arranged on the inner side of the outer weather strip. However, if a plurality of seal members are arranged, the number of parts increases and the cost increases, and the accuracy management of each part becomes complicated. Further, when a plurality of seal members or a large seal member is used, a large space is required and the space efficiency is deteriorated.

  The present invention has been made on the basis of the above problem awareness, and an object of the present invention is to provide a waterproof structure for a vehicle door frame having a simple structure and excellent water tightness.

  A waterproof structure for a vehicle door frame according to the present invention includes a window glass that opens and closes a window opening of a vehicle door, an exterior member that has an edge portion that faces the edge surface of the window glass, and constitutes the outer surface of the door frame; And a seal member that is sandwiched between the edge surface of the glass and the edge portion of the exterior member and extends in the longitudinal direction of the door frame. The seal member has a hollow drainage channel extending in the longitudinal direction of the door frame inside the sandwiched portion sandwiched between the window glass and the exterior member, and has a through portion that communicates the drainage channel with the outside. .

  The sealing member may have a concave portion that is concave toward the drainage channel on the side facing the edge of the exterior member, and a through portion may be formed in the concave portion. By arranging the edge of the exterior member in the recess of the seal member, water can be reliably guided from the penetrating portion to the drainage channel.

  The edge of the exterior member has a shape that protrudes toward the inside of the vehicle, and the seal member includes an adhesion wall portion that is in close contact with a surface facing the edge surface of the window glass, and an edge of the exterior member. It is preferable to have a retaining portion for restricting the movement of the seal member to the outer side of the portion facing the end surface facing the vehicle inner side, and to have a penetrating portion between the adhesion wall portion and the retaining portion.

  In this case, the retaining portion may have an inclination that increases the distance in the vehicle interior / exterior direction with respect to the contact wall portion as it proceeds inward of the drainage channel. Thereby, water can be made to easily flow into the drainage channel through the penetration portion.

  The seal member may have a through portion that opens toward the exterior member side, and the edge of the exterior member may be configured to be inserted through the through portion to the inside of the drainage channel of the seal member. Accordingly, the degree of coupling between the exterior member and the seal member can be increased, and the ease of guiding water from the edge of the exterior member into the drainage channel of the seal member can be improved.

  ADVANTAGE OF THE INVENTION According to this invention, the waterproof structure of the vehicle door frame which is excellent in watertightness can be obtained by the simple structure of providing a drainage channel and a penetration part in a sealing member.

The partition wall portion 31d extends from the base portion 31a in the vehicle exterior direction, and a bent portion 31e that bends forward is provided at the vehicle outer end of the rear wall portion 31c. In addition, a bent portion that bends forward is also provided at the end of the partition wall 31d on the vehicle outer side.

  The guide rail 31 is disposed so as to be fitted inside the open portion of the inner side of the bag-like portion 30a of the inner sash 30, and the front wall portion 31b and the rear wall portion 31c are arranged in the vehicle front-rear direction by the bag-like portion 30a. It is sandwiched. A part of the guide rail 31 protrudes outside the bag-shaped portion 30a in a state of being fitted to the bag-shaped portion 30a. In particular, a part of the rear wall portion 31c of the guide rail 31 protrudes from the end portion of the rear side wall portion 30d (the end portion on the vehicle outer side connected to the rearward extending portion 30e) to constitute the positioning portion 31f. .

  The window glass W is supported and guided by the guide rail 31 so as to be movable up and down. That is, the guide rail 31 constitutes a main body portion of the upright pillar sash 15 together with the inner sash 30 and also functions as a member for supporting and guiding the window glass W in the window regulator 18.

  The shoe base 21 of the slider 20 included in the window regulator 18 is bonded and fixed to a part of the vehicle inner side surface W2 of the window glass W (see FIGS. 2 and 3). The slider 20 includes a shoe base 21 and a shoe 22. As shown in FIG. 1, two sliders 20 are provided that are spaced apart in the vertical direction.

  The space in the guide rail 31 is partitioned into a first partition 31g and a second partition 31h in the front-rear direction by a partition wall portion 31d. The shoe 22 of the slider 20 is accommodated in the first section 31g so as to be slidable in the vertical direction (the direction perpendicular to the paper surface shown in FIGS. 2 and 3). A wire end support portion 23 connected to the shoe base 21 of the slider 20 is accommodated in the second section 31h (see FIG. 3). A wire end (not shown) provided at the end of a wire 24 that drives the slider 20 is connected to the wire end support portion 23. Of the two sliders 20 shown in FIG. 1, only the upper slider 20 has the wire end support portion 23.

  As shown in FIG. 4, the wire 24 is routed along the longitudinal direction of the guide rail 31. A motor unit 25 is attached to the guide rail 31. The motor unit 25 includes a drum that is rotationally driven by the driving force of the motor 25a, and a pair of wires 24 are wound around the drum. One wire 24 shown in FIG. 4 extends upward from the drum along the vehicle inner side of the base portion 31a of the guide rail 31, and the vehicle outer side of the base portion 31a by the guide pulley 26 supported near the upper end of the guide rail 31 ( It is guided to the second section 31h) and connected to the wire end support portion 23 from above. The other wire 24 extends upward from the drum along the vehicle outer side of the base portion 31a of the guide rail 31, and is connected to the wire end support portion 23 from below. The window regulator 18 pulls the slider 20 up and down to drive the window glass W up and down by controlling the winding or unwinding of each wire 24 by driving the motor 25a.

  Of the standing pillar sash 15, the inner sash 30 has a length from the door corner portion 17 to the vicinity of the upper edge of the door panel 11. On the other hand, since the guide rail 31 guides the slider 20 to the fully open position of the window glass W, it has a length inserted to the lower part of the door panel 11 (see FIG. 1).

  The garnish 32 is an exterior member that is attached to the vehicle exterior side of the main body portion of the upright column sash 15 including the inner sash 30 and the guide rail 31 and forms the appearance of the upright column sash 15. ).

  The garnish 32 has a cover portion 32 a that covers the vehicle exterior side of the design portion 30 b of the inner sash 30. As shown in FIG. 2, the cover portion 32a has a width that covers the entire design portion 30b in the vehicle front-rear direction. A rear edge (32b) having a shape that curves (bends) and protrudes toward the vehicle inner side and covers the rear end of the design portion 30b is provided at the rear edge (outer peripheral side) of the cover portion 32a. Yes. A front edge 32c that is curved (bent) and protrudes toward the inside of the vehicle and enters the first space U1 is provided at the edge on the front side (inner circumferential side) of the cover portion 32a.

  The garnish 32 is fixed to the design portion 30 b of the inner sash 30. The means for fixing the garnish 32 is not shown. With the garnish 32 attached to the design portion 30b, the vehicle outer side surface 32d facing the vehicle outer side is substantially flush with the vehicle outer side surface W1 of the window glass W. That is, a so-called flash surface structure is obtained in which there is no uneven relationship between the wind glass W and the garnish 32 in the vehicle interior / exterior direction. The front edge portion 32c of the garnish 32 faces the edge surface W3 of the window glass W with a predetermined interval in the front-rear direction. The front edge portion 32c has an inclined shape that increases the forward protrusion amount (decreases the distance from the edge surface W3 of the window glass W) as it moves away from the cover portion 32a and advances to the front end of the vehicle interior. .

  2 and 3, with the window glass W closed, the positioning part 31f of the guide rail 31, the connection part 30c of the inner sash 30, the front edge part 32c of the garnish 32, and the window glass W A first space U1 defined by the edge surface W3 is formed. Further, a second space U2 communicating with the first space U1 is formed between the bent portion 31e of the guide rail 31 and the vehicle interior side surface W2 of the window glass W.

  The elastic cover 33 is made of an elastic body, is held inside the first space U1 and the second space U2, and extends in the longitudinal direction of the upright column sash 15. The elastic cover 33 includes a first water stop portion 33a disposed in the first space U1 and a second water stop portion 33b disposed in the second space U2.

  The first water stop portion 33a of the elastic cover 33 includes a base portion 33c positioned on the vehicle inner side, a front side wall portion 33d positioned on the front side, a rear side wall portion 33e positioned on the rear side, and a vehicle outer side positioned on the vehicle outer side. And a wall portion 33f. At the rear end portion of the first water stop portion 33a, a retaining portion 33g that protrudes rearward is formed. The first water stop portion 33a is hollow inside the base portion 33c, the front side wall portion 33d, the rear side wall portion 33e, the vehicle outer side wall portion 33f, and the retaining portion 33g, and this internal space is connected to the drainage channel 33h. It has become. Between the rear side wall part 33e and the retaining part 33g, a through part 33i is formed which communicates the external space (first space U1) of the first water stop part 33a and the drainage channel 33h.

  By bringing the inner surface of the base portion 33c into contact with the rearward extending portion 30e of the inner sash 30, the position of the elastic cover 33 in the vehicle interior / exterior direction is determined. By bringing the front end portion of the base portion 33c into contact with the positioning portion 31f of the guide rail 31, the position of the elastic cover 33 in the vehicle front-rear direction (inner and outer peripheral directions) is determined. In this state, the front side wall portion 33d abuts on the edge surface W3 of the window glass W, and the rear side wall portion 33e abuts on the front edge portion 32c of the garnish 32. 2 and 3 show the shape of the elastic cover 33 in a free state. The elastic cover 33 is elastically deformed from the free state by being sandwiched by the wind glass W and the garnish 32 from the front and rear, and the front side wall 33d and the rear side wall 33e are respectively the edge surface W3 of the wind glass W and the front edge of the garnish 32. Adheres closely to the part 32c. As a result, the first water stop portion 33a of the elastic cover 33 is watertightly sealed between the wind glass W and the garnish 32.

  The retaining portion 33g of the elastic cover 33 is positioned to face the end surface of the front edge portion 32c of the garnish 32 facing the vehicle inside. Then, the movement of the elastic cover 33 to the vehicle outer side (dropping from the first space U1) is prevented by the relationship between the retaining portion 33g and the vehicle inner end surface of the front edge portion 32c.

  The rear side wall portion 33e of the elastic cover 33 has a shape that increases along the front edge portion 32c of the garnish 32 so as to increase the amount of protrusion into the drainage channel 33h as it moves away from the vehicle outer wall portion 33f and toward the vehicle inner side. Yes. In other words, the first water stop portion 33a is formed with a recess that is concave toward the drainage channel 33h by the rear side wall portion 33e and the retaining portion 33g of the elastic cover 33. The front edge 32c of the garnish 32 is arranged in the recess.

  The second water stop portion 33b of the elastic cover 33 is a cantilevered lip portion that protrudes forward from between the first water stop portion 33a and the front side wall portion 33d in the first water stop portion 33a. The second water stop portion 33b is elastically deformed by being sandwiched between the vehicle interior side surface W2 of the window glass W and the bent portion 31e of the guide rail 31, and tightly seals between the window glass W and the bent portion 31e. The tip of the second water stop portion 33b is in contact with a part of the slider 20 accommodated in the guide rail 31 (first section 31g).

  As described above, the elastic cover 33 is closed in a watertight manner over the first space U1 and the second space U2 in an elastically deformed state, and prevents water from entering from the peripheral edge of the window glass W to the inside of the vehicle. The elastic cover 33 is further provided with a through portion 33i that allows the drainage channel 33h to communicate with the inside and outside of the drainage channel 33h, thereby obtaining a higher level of waterproof performance.

  Specifically, the water flowing from the vehicle outer surface 32d of the garnish 32 toward the elastic cover 33 and the water flowing to the vehicle rear wall 33f of the elastic cover 33 toward the rear side wall 33e are formed in the shape of the front edge 32c of the garnish 32. To enter the first space U1. The rear side wall 33e of the elastic cover 33 is in close contact with the front edge 32c, and blocks water from entering the first space U1. However, when the water pressure is strong or when the degree of adhesion of the rear side wall portion 33e to the front edge portion 32c is low due to an assembling error or the like, there is a possibility that water may enter the vehicle inner side than the rear side wall portion 33e.

  The water that has passed between the front edge portion 32c of the garnish 32 and the rear side wall portion 33e of the elastic cover 33 reaches the formation portion of the penetration portion 33i located on the vehicle inner side of the rear side wall portion 33e. Then, water enters the drainage channel 33h through the through portion 33i. The drainage channel 33h forms a flow path extending in the vertical direction (longitudinal direction of the upright column sash 15) without having an opening other than the through portion 33i. Therefore, the water that has entered the drainage channel 33h falls downward through the drainage channel 33h due to gravity. The door 10 includes a drainage structure (not shown) capable of draining water reaching the lower end of the drainage channel 33h to the outside of the vehicle.

  In this manner, by adopting a configuration in which water is guided into the hollow drainage channel 33h of the elastic cover 33, it becomes difficult for water to flow to the inside of the vehicle through the periphery of the elastic cover 33, and high water tightness can be obtained. it can. Since the through portion 33i is formed in the first water stop portion 33a having the drainage channel 33h, the water tightness can be improved without increasing the number of parts and increasing the cost. Moreover, since the drainage channel 33h is located inside the space (first space U1) partitioned by the wind glass W and the garnish 32, a special space for installing the drainage channel 33h is not required. It can be configured to save space.

  In particular, in the present embodiment, a recess (rear side wall portion 33e and retaining portion 33g) that is concave toward the drainage channel 33h side on the side (rear) facing the front edge portion 32c of the garnish 32 in the elastic cover 33. The through portion 33i is formed in the recess. The front edge portion 32c of the garnish 32 is disposed in the recess of the elastic cover 33, and the front end of the front edge portion 32c is positioned in the vicinity of the through portion 33i in the recess. Accordingly, the through portion 33i is positioned on the extension of the water traveling direction to advance toward the inside of the vehicle along the front edge portion 32c, and has a structure that allows water to easily flow into the drainage channel 33h from the through portion 33i. .

  Further, as a structure for preventing the elastic cover 33 from coming off, a retaining portion 33g of the elastic cover 33 is located opposite to an end surface of the front edge portion 32c of the garnish 32 facing the vehicle interior, and the elastic cover 33 is separated from the front edge portion 32c. The gap between the stoppers 33g is set narrow. For this reason, the flow of water that does not enter the drainage channel 33h from the through portion 33i and passes between the retaining portion 33g and the front edge portion 32c and travels toward the vehicle interior (in the first space U1) is less likely to occur.

  Therefore, according to the configuration of the present embodiment, in the elastic cover 33, the water that has passed through the water stop region by the rear side wall portion 33e can be surely guided and drained into the drainage channel 33h without proceeding to the vehicle interior side. it can.

  The elastic cover 33 is also disposed adjacent to the garnish 32 to prevent a part of the door frame 12 disposed on the vehicle inner side from being visually recognized from the vehicle outer side. The elastic cover 33 covers the connection portion 30c of the inner sash 30, the entire second section 31h of the guide rail 31, and a part of the first section 31g so that the elastic cover 33 is not visible from the outside of the vehicle.

  As described above, in the upright pillar sash 15 constituting the door 10 of the present embodiment, the through-hole 33i is formed in the elastic cover 33, and the space formed in the first water stop 33a is used as the drainage channel 33h. The single elastic cover 33 can provide high water tightness. The first water stop portion 33a of the elastic cover 33 fits in the space between the wind glass W and the garnish 32, and can be arranged in a space-saving manner.

  Further, the upright pillar sash 15 is configured to be excellent in assembling property of the elastic cover 33. As described above, the front edge portion 32c of the garnish 32 is disposed in a recess formed by the rear side wall portion 33e and the retaining portion 33g in the elastic cover 33. Therefore, it can be handled as a subassembly in which the elastic cover 33 is assembled to the garnish 32 in advance, and the garnish 32 and the elastic cover 33 can be assembled to the vertical pillar sash 15 at a time.

  After the elastic cover 33 is assembled, the position of the elastic cover 33 is stabilized with respect to the main body portion of the upright pillar sash 15 by the abutment of the base portion 33c against the rearwardly extending portion 30e of the inner sash 30 and the positioning portion 31f of the guide rail 31. Can be made. Furthermore, the high positional stability of the elastic cover 33 can be obtained with respect to the garnish 32 by the insertion structure of the front edge portion 32 c of the garnish 32 into the recess of the elastic cover 33. Therefore, regarding the elastic cover 33, it is possible to achieve both high water tightness and excellent assemblability.

  The waterproof structure in the present invention is not limited to the above embodiment. For example, FIGS. 5 to 7 show modifications of the upright column sash 15 in which the detailed structures of the elastic cover 33 and the garnish 32 are different. In these modifications, portions common to the previous embodiment are denoted by common reference numerals, and description thereof is omitted.

  In the first modification of the upright pillar sash 15 shown in FIG. 5, the front edge portion 32e provided on the garnish 32 is longer than the front edge portion 32c of the previous embodiment, and the vehicle inner side as it advances forward (inner peripheral side). It has an inclined shape that increases the amount of protrusion. And the front edge part 32e of the garnish 32 penetrates the penetration part 33j formed in the elastic cover 33, and is inserted to the inside of the drainage channel 33h.

  Similarly, in the second modification of the upright pillar sash 15 shown in FIG. 6, the front edge portion 32 f provided in the garnish 32 passes through the through portion 33 k formed in the elastic cover 33 and is inserted into the drainage channel 33 h. Yes. The front edge portion 32f has a shape that protrudes toward the vehicle inner side with respect to the cover portion 32a of the garnish 32 and then bends forward (inner circumferential side). The front edge portion 32e shown in FIG. The insertion direction with respect to the drainage channel 33h is different.

  In the configuration of the first and second modified examples shown in FIGS. 5 and 6, the front edge 32e and the front edge 32f provided on the garnish 32 are formed by the recesses of the elastic cover 33 (the rear side wall 33e and the retaining portion 33g). In addition, it is not only located within, but also inserted through the through portions 33j and 33k to the inside of the first water stop portion 33a. Therefore, the garnish 32 and the elastic cover 33 are more closely coupled, and the handling property as a subassembly in which the garnish 32 and the elastic cover 33 are combined is improved. In addition, the water flowing along the front edge portion 32e and the front edge portion 32f of the garnish 32 can be easily guided into the drainage channel 33h of the elastic cover 33, and the effect of making it difficult for water to leak around the first space U1 and the like. Is obtained.

  In the third modification of the upright pillar sash 15 shown in FIG. 7, the through-hole 33m formed in the elastic cover 33 has a shape that can easily guide the water transmitted from the front edge 32c of the garnish 32 into the drainage channel 33h. Yes. More specifically, the retaining portion 33n of the elastic cover 33 has an inclined shape that protrudes toward the vehicle inner side from the rear (outer peripheral side) to the front (inner peripheral side). That is, the retaining portion 33n has an inclination that increases the distance from the rear side wall portion 33e in the vehicle interior / exterior direction as it goes inward of the first water retaining portion 33a.

  As a result, when the water that has entered between the front edge portion 32c of the garnish 32 and the rear side wall portion 33e of the elastic cover 33 reaches the position of the retaining portion 33n, the inclination of the retaining portion 33n causes the depth of the through portion 33m to be increased. Water easily flows toward the side (in the drainage channel 33h). As a result, water leakage to the surroundings such as the first space U1 is less likely to occur, and an effect of improving waterproof performance can be obtained.

  The elastic cover 33 of the above embodiment and each modified example includes a second water stop portion 33b in addition to the first water stop portion 33a, and not only the edge surface W3 of the window glass W but also the vehicle inner side surface W2. High watertightness is obtained. However, when paying attention to the improvement of water tightness using the drainage channel 33h and the through portion 33i on the first water stop portion 33a side, the present invention is also applied to a configuration in which the elastic cover 33 does not include the second water stop portion 33b. Is applicable.

  In the above-described embodiment and each modified example, the guide rail 31 includes the positioning portion 31f that determines the position of the elastic cover 33 in the front-rear direction (inner and outer peripheral directions), but the inner sash 30 may be provided with a similar positioning portion. Is possible.

  Further, in the above-described embodiment and each modification, the window regulator 18 is incorporated in the upright column sash 15, and the guide rail 31 involved in the support and guidance of the window glass W constitutes a part of the main body of the upright column sash 15. However, it is also possible to apply the present invention to a door frame in which a window regulator component is not incorporated in a vertical pole sash.

  Moreover, although said embodiment and each modification are intended for the waterproof structure between the garnish 32 and the window glass W in the vertical pillar sash 15, if it is a site | part provided with the exterior member equivalent to the garnish 32 The door frame can be applied to portions other than the vertical pillar sash.

  Although the said embodiment and each modification are applied to the door 10 of the right front part of a vehicle, the application to doors other than this is also possible.

  The embodiments of the present invention are not limited to the above-described embodiments and modifications, and various changes, substitutions, and modifications may be made without departing from the spirit of the technical idea of the present invention. Furthermore, if the technical idea of the present invention can be realized in another way by technological advancement or another derived technique, the method may be used. Accordingly, the claims cover all embodiments that can be included within the scope of the technical idea of the present invention.
