Description

  The present invention relates to a glass run disposed on an automobile door, and particularly belongs to the technical field of a structure that is attached to a wind frame frame from the outside of a passenger compartment.

  In general, there are a plurality of types of doors provided on the side of an automobile. One of them is a door having a window frame (also referred to as a sash) that holds a peripheral edge of a window glass. The door having the window frame frame is provided with a glass run for sealing between the window frame frame and the window glass.

  The glass runs disclosed in Patent Literatures 1 to 5 are attached to the wind frame frame from the outside of the passenger compartment. This type of glass run is called a hidden type that partially covers and hides the wind frame from the outside of the passenger compartment, and may be employed, for example, due to vehicle design requirements.

  In the hidden type, a glass run attachment plate portion to which the glass run body is attached is provided on the wind frame so as to protrude outward from the passenger compartment. On the other hand, the glass run body is formed with an insertion groove into which the glass run mounting plate portion of the wind frame frame is inserted. The glass runs of Patent Documents 1 to 5 are attached to the wind frame frame from the outside of the passenger compartment by inserting an insertion groove in the glass run attachment plate portion of the wind frame frame. The holding power can be obtained.

  In Patent Documents 1 to 5, a molding member made of a metal material or the like is attached so as to cover the outside of the cabin of the glass run body. Further, a body seal lip portion protruding upward is integrally formed on the upper portion of the glass run body. The vehicle body seal lip portion is for contacting the vehicle body panel when the door is closed to seal between the vehicle body panel and the door.

  The vehicle body seal lip portions of Patent Documents 1 and 2 are arranged so as to be separated from the molding member attached to the glass run body. Moreover, the vehicle body seal lip part of patent documents 3 and 4 is arranged so that the base end may contact the molding member attached to the glass run body. Further, FIGS. 2 to 4 of Patent Document 5 disclose that the vehicle body seal lip portion is disposed so as to be separated from the molding member attached to the glass run body, and FIG. It is disclosed that the base end portion of the seal lip portion is arranged so as to contact a molding member attached to the glass run body.

  By the way, when attaching the molding member which consists of another member to a glass run main body like patent documents 1-5, since a molding member is long and long in the direction of vehicles front and back, it is rear from the glass run main body, for example from the front side. A method is conceivable in which a rail-shaped portion extending toward the side is set, and the molding member is attached to the glass run body by sliding the molding member along the rail-shaped portion.

  However, as disclosed in FIG. 5 of Patent Documents 3, 4, and 5, when the base end of the vehicle body seal lip is disposed so as to contact the molding member, the molding member is attached to the glass run body. When trying to slide, the base end of the vehicle body seal lip is in contact, and frictional resistance is generated between the molding member and the vehicle body sealing lip, making it difficult to slide the molding member against the glass run body. As a result, the mounting workability of the molding member is deteriorated.

  On the other hand, as disclosed in FIGS. 2 to 4 of Patent Documents 1, 2, and 5, when the base end of the vehicle body seal lip is disposed away from the molding member, the molding member is attached to the glass run body. It is considered that the molding member can be easily slid because no frictional resistance is generated between the lip portion and the vehicle body seal lip.

  However, the fact that the base end portion of the vehicle body seal lip portion is arranged away from the molding member means that a gap is formed between the base end portion of the vehicle body seal lip portion and the molding member, and the installation is completed. It becomes difficult to regulate the movement of the molding member later. Specifically, for example, when a hand touches the molding member, the molding member easily moves in the longitudinal direction, which may cause a misalignment of the molding member and deteriorate the appearance of the appearance.

  Since the molding member is long in the vehicle longitudinal direction as described above, if there is a gap between the body seal lip portion of the glass run body and the molding member, the gap is kept constant over the entire vehicle longitudinal direction. This is difficult, and the size of the gap differs depending on the part, which may deteriorate the appearance of the appearance.

  The present invention has been made in view of such points, and the purpose of the present invention is to improve the mounting workability of the molding member when the molding member can be mounted by sliding it on the glass run body. It is to improve the appearance of the appearance after installation.

  In order to achieve the above object, according to the present invention, when the automobile door is in the open state, the vehicle body seal lip portion is arranged so as to be separated from the molding member, while when the automobile door is in the closed state, the vehicle body seal lip portion is The molding member is brought into contact with the panel by elastic deformation in contact with the panel.

  According to a first aspect of the present invention, there is provided a glass run for an automobile door which is attached to a wind frame frame extending so as to form a window opening of the automobile door from the outside of the passenger compartment and seals between the window frame frame and the wind glass. The glass run has a glass run body having an insertion groove into which a glass run mounting plate portion extending to the outside of the passenger compartment formed on the upper side of the wind frame frame is inserted, and a molding member attached to the outer side of the passenger compartment of the glass run main body. The glass run body includes a vertical plate portion extending in the vehicle front-rear direction along an end of the glass run mounting plate portion on the vehicle exterior side, and the upper side of the glass run mounting plate portion from the upper side of the vertical plate portion to the vehicle interior side. An upper plate portion that extends toward the vehicle interior, and a lower plate portion that extends from the lower side of the vertical plate portion toward the vehicle interior side under the glass run mounting plate portion. A rail-shaped portion that engages with the molding member and guides the molding member in the longitudinal direction of the vehicle is provided to extend in the longitudinal direction of the vehicle. A vehicle body made of an elastic material that protrudes upward on the upper side and outside the vehicle compartment and that contacts the vehicle body panel and seals between the vehicle body panel and the glass run body when the automobile door is in a closed state A seal lip portion is provided, and the vehicle body seal lip portion is separated from an upper end portion of the molding member when the automobile door is in an open state, and is in contact with the vehicle body panel and elastic when the vehicle door is in a closed state. The upper surface of the molding member is brought into contact with the molding member by being deformed.

  According to this configuration, when the molding member is attached to the glass run body, the molding member is slid in the vehicle front-rear direction along the rail shape portion with the molding member engaged with the rail shape portion of the glass run body. Let When performing the work of attaching the molding member to the glass run body, since the automobile door is normally open, the vehicle body seal lip portion of the glass run body is not in contact with the vehicle body panel. It will be located away from the upper end of the. Therefore, no frictional resistance is generated between the vehicle body seal lip portion and the molding member, so that the molding member can be easily slid and the mounting workability is improved.

After the molding member is attached to the glass run body, when the automobile door is closed, the vehicle body seal lip portion contacts the vehicle body panel and elastically deforms, and the vehicle body seal lip portion contacts the upper end portion of the molding member. That is, the shape of the vehicle body seal lip portion changes between a separated state away from the upper end portion of the molding member and a contact state in contact with the upper end portion of the molding member.
Thereby, since frictional resistance is generated between the seal lip portion and the molding member, the molding member is difficult to move in the longitudinal direction. Therefore, the misalignment of the molding member is suppressed and the appearance is improved.

  In addition, since the vehicle body seal lip portion contacts the upper end portion of the molding member, there is no gap between the vehicle body sealing lip portion and the molding member, so that the appearance is improved.

  According to a second invention, in the first invention, a groove extending in the vehicle front-rear direction is formed at a base end portion of the vehicle body seal lip portion.

  According to this configuration, when the automobile door is closed and the vehicle body seal lip portion contacts the vehicle body panel, the vehicle body seal lip portion is reliably elastically deformed in the vicinity of the groove so that the vehicle body seal lip portion is made of the molding member.

  According to this configuration, after the glass run main body and the vehicle body seal lip portion are integrally formed, the workability of attaching the molding member can be further improved without any additional processing.

  A sixth invention is characterized in that, in any one of the first to fifth inventions, a base end portion of the vehicle body seal lip portion is configured to be softer than the base end portion compared to the front end side. To do.

  According to this configuration, since the vicinity of the base end portion of the vehicle body seal lip portion is easily elastically deformed, the vehicle body seal lip portion can be reliably brought into contact with the upper end portion of the molding member.

  According to a seventh invention, in any one of the first to sixth inventions, the vehicle body seal lip portion has a contact portion that contacts the upper end portion of the molding member when the automobile door is in a closed state. It is integrally formed so as to protrude toward the surface.

  According to this structure, since the contact part of the vehicle body seal lip part protrudes toward the vehicle compartment outer side, it contacts the upper end part of a molding member reliably.

  According to the first invention, when the automobile door is in the open state, the vehicle body seal lip portion is separated from the upper end portion of the molding member, so that the mounting workability is improved when the molding member is slid and attached to the glass run body. Can do. In addition, when the automobile door is in the closed state, the vehicle body seal lip portion contacts the upper end of the molding member, so that the movement of the molding member can be suppressed, and the gap between the molding member and the glass run body can be eliminated. Appearance can be improved.

  According to the second invention, since the groove is formed in the base end portion of the vehicle body seal lip portion, the vehicle body seal lip portion can be reliably elastically deformed in the vicinity of the groove when the automobile door is closed. The vehicle body seal lip can be reliably brought into contact with the upper end of the molding member.

  According to the third invention, since the groove at the base end portion of the vehicle body seal lip portion is opened outside the vehicle compartment, the vehicle body seal lip portion is easily elastically deformed toward the vehicle compartment outside, and the vehicle body seal lip portion is The upper end of the molding member can be reliably brought into contact.

  According to the fourth invention, since the base end portion of the vehicle body seal lip portion is thinned, the vehicle body seal lip portion can be elastically deformed in the vicinity of the base end portion when the automobile door is closed. The vehicle body seal lip portion can be reliably brought into contact with the upper end portion of the molding member.

  According to the fifth invention, since the outer side wall portion is provided at the lower end portion of the vertical plate portion and the groove is formed at the base end portion of the outer side wall portion, after molding, the molding is not performed separately. The attachment workability of the member can be improved.

  According to the sixth invention, since the base end portion of the vehicle body seal lip portion is softened, the vehicle body seal lip portion can be reliably elastically deformed in the vicinity of the base end portion when the automobile door is closed. The vehicle body seal lip can be reliably brought into contact with the upper end of the molding member.

  According to the seventh aspect, since the contact portion is integrally formed with the vehicle body seal lip portion, the contact portion of the vehicle body seal lip portion can be reliably brought into contact with the upper end portion of the molding member.

By forming the groove 29a in the base end portion of the outer vehicle body seal lip portion 29, the thickness of the base end portion of the outer vehicle body seal lip portion 29 is thinner than the thickness of the front end side of the base end portion. Will be set. As described above, the base end portion of the outer vehicle body seal lip portion 29 is relatively thin, so that the base end portion of the outer vehicle body seal lip portion 29 is compared to the front end side of the base end portion. It will be constructed softly. Therefore, when an external force is applied in the vehicle interior / exterior direction with respect to the front end side of the base end portion of the outer vehicle body seal lip portion 29, the outer vehicle body seal lip portion 29 starts from the vicinity of the base end portion in the direction in which the external force acts. Elastically deforms so that it falls easily. Further, when the outer vehicle body seal lip portion 29 receives an external force in the vehicle interior / exterior direction, not only the vicinity of the base end portion but also the entire body is easily elastically deformed.

  Further, the outer body seal lip 29 is integrally formed so that a contact portion 29b that contacts the upper end portion of the molding member 40 protrudes toward the outside of the vehicle compartment when the automobile door 1 is in the closed state. The contact portion 29 b is located immediately above the groove 29 a in a portion near the base end portion of the outer vehicle body seal lip portion 29. The vertical cross-sectional shape of the contact portion 29b is tapered so that the dimension in the vertical direction becomes shorter toward the tip in the protruding direction (outside the passenger compartment). The tip of the contact portion 29b mainly contacts the upper end of the molding member 40 and is elastically deformed.

  Further, the outer vehicle body seal lip portion 29 is integrally formed with the glass run main body 21 so as to be separated from the upper end portion of the molding member 40 in a state where no external force is applied. That is, as shown in FIG. 2, after the glass run body 21 and the outer vehicle body seal lip portion 29 are formed, the outer vehicle body seal lip portion 29 is in a posture extending in the vertical direction, and the contact portion 29 b is formed of the molding member 40. It is away from the upper end to the vehicle interior side. As a result, a predetermined gap is formed between the tip end portion of the contact portion 29 b and the upper end portion of the molding member 40. The size of the gap can be set to about 0.5 mm to 2.0 mm, for example, but is not limited to this range, and the size can avoid contact between the contact portion 29b and the molding member 40. Just set it up.

(Configuration of molding material)
As shown in FIG. 3, the molding member 40 includes a resin fixing member 41 and a metal outer covering member 42. The fixing member 41 is a long member that is long in the front-rear direction so as to follow the rail-shaped portion 26 of the glass run body 21. On the upper portion of the fixing member 41, an upper bent portion 41a that is bent so as to surround the upper protruding portion 26b of the rail-shaped portion 26 from above is provided. The upper bent portion 41a engages with the upper protruding portion 26b of the rail-shaped portion 26. In addition, a lower bent portion 41b that is bent to surround the lower protrusion 26c of the rail-shaped portion 26 from the lower side is provided at the lower portion of the fixing member 41. The lower bent portion 41b engages with the lower protrusion 26c of the rail-shaped portion 26. A portion of the fixing member 41 between the upper bent portion 41 a and the lower bent portion 41 b extends substantially flat so as to follow the outer surface of the rail-shaped portion 26.

  Further, a lower protruding portion 41 c that protrudes downward is formed on the lower bent portion 41 b of the fixing member 41. The lower protrusion 41c extends in the front-rear direction. The fixing member 41 can be slid in the longitudinal direction with respect to the glass run body 21 with the upper bent portion 41a and the lower bent portion 41b engaged with the upper protruding portion 26b and the lower protruding portion 26c, respectively. It has become.

  The outer covering member 42 is made of, for example, a metal material such as a stainless steel plate or an aluminum alloy, but is not limited thereto, and may be made of a member obtained by applying metal plating to a resin material. That is, any member that can give a metallic accent to the window frame 3 of the automobile door 1 may be used.

  On the upper portion of the outer covering member 42, an upper bent portion 42a formed so as to surround the upper bent portion 41a of the fixing member 41 from above is formed. On the other hand, a lower bent portion 42b that is bent to surround the lower protruding portion 41c of the fixing member 41 from the lower side is formed at the lower portion of the outer covering member 42. By holding the fixing member 41 in the vertical direction between the upper bent portion 42a and the lower bent portion 42b of the outer covering member 42, the outer covering member 42 and the fixing member 41 are relatively difficult to move in the longitudinal direction. It is assembled and integrated. When the fixing member 41 and the outer covering member 42 are assembled and integrated, the end portion in the longitudinal direction of the fixing member 41 is inserted from the end portion in the longitudinal direction of the outer covering member 42, and the end portion of the fixing member 41 and the outer side What is necessary is just to make the edge part of the coating | coated member 42 correspond.

  The lower ridge portion 27b of the outer side wall portion 27 of the glass run main body 21 is in contact with the lower bent portion 42b of the outer covering member 42 from the lower side. Further, a portion between the upper bent portion 42 a and the lower bent portion 42 b of the outer covering member 42 extends substantially flat so as to follow the outer surface of the vehicle interior of the fixing member 41.

  Although not shown, the molding member 40 may be composed of one component. In this case, metal plating or the like may be applied to the outer surface of the passenger compartment of a member such as the fixing member 41.

(Glass run installation procedure)
Next, how to attach the glass run 20 configured as described above will be described. First, the glass run body 21 is attached to the wind frame 3 of the automobile door 1. At this time, the glass run main body 21 is disposed outside the cabin of the wind frame 3 and the open portion of the insertion groove 21a is opposed to the end of the glass run mounting plate 10 on the outside of the cabin. Thereafter, the glass run body 21 and the window frame 3 are relatively moved to insert the insertion groove 21 a into the glass run attachment plate portion 10. At this time, the glass run body 21 is moved in a direction approaching the window frame 3.

  Thereafter, the molding member 40 is attached to the glass run body 21. When the molding member 40 is attached to the glass run body 21, the molding member 40 is engaged with the rail-shaped portion 26 of the glass run body 21. For example, the front end portion of the fixing member 41 of the molding member 40 is inserted into the rear end portion of the rail-shaped portion 26, and the upper bent portion 41 a is engaged with the upper protruding portion 26 b of the rail-shaped portion 26, and the lower bent portion 41b is engaged with the lower protrusion 26c of the rail-shaped portion 26. In this state, the molding member 40 is slid in the forward direction of the glass run body 21 along the rail-shaped portion 26. When the rear end portion of the fixing member 41 of the molding member 40 is inserted into the front end portion of the rail-shaped portion 26, the molding member 40 may be slid in the rear direction of the glass run body 21.

  When the work for attaching the molding member 40 to the glass run body 21 is performed, the automobile door 1 is normally in an open state, so that the outer body seal lip 29 of the glass run body 21 is not attached to the body panel P as shown in FIG. There is no contact. Accordingly, the outer vehicle body seal lip 29 of the glass run body 21 is positioned away from the upper end of the molding member 40. Therefore, since frictional resistance does not occur between the outer vehicle body seal lip 29 and the molding member 40, the molding member 40 can be easily slid, and mounting workability is improved.

(Door closed)
After the molding member 40 is attached to the glass run body 21, when the automobile door 1 is closed, the outer vehicle body seal lip 29 comes into contact with the vehicle body panel P as shown in FIG. As a result, an external force from the vehicle body panel P toward the vehicle compartment outside acts on the outer vehicle body seal lip portion 29. Since the base end of the outer body seal lip portion 29 to which an external force directed toward the outside of the passenger compartment acts is thinned, the outer body seal lip 29 is easily elastically deformed so as to fall to the outside of the passenger compartment starting from the vicinity of the base end. In this state, the contact portion 29b of the outer vehicle body seal lip portion 29 contacts the upper end portion of the molding member 40, and the vehicle interior side of the outer vehicle body seal lip portion 29 contacts the vehicle body panel P. Further, the loop lip portion 28 of the glass run body 21 also contacts the vehicle body panel P. Sealing performance can be ensured by the outer vehicle body seal lip portion 29 and the inner vehicle body seal lip portion 28.

  When the contact portion 29b of the outer vehicle body seal lip portion 29 comes into contact with the upper end portion of the molding member 40, a frictional resistance is generated between the outer vehicle body seal lip portion 29 and the molding member 40. It becomes difficult to move. Therefore, for example, even if the hand touches the molding member 40, the molding member 40 is not easily displaced, and the appearance is improved.

  Further, since the outer vehicle body seal lip portion 29 comes into contact with the upper end portion of the molding member 40, there is no gap between the outer vehicle body seal lip portion 29 and the molding member 40. This also improves the appearance of the appearance.

  Furthermore, since there is no gap between the outer vehicle body seal lip portion 29 and the molding member 40, wind noise during traveling can be reduced.

(Effect of embodiment)
As described above, according to the glass run 20 for an automobile door according to this embodiment, the outer vehicle body seal lip 29 is separated from the upper end of the molding member 40 when the automobile door 1 is in an open state. When the molding member 40 is mounted by sliding in the longitudinal direction, the mounting workability can be improved. Further, when the automobile door 1 is in the closed state, the outer vehicle body seal lip portion 29 contacts the upper end portion of the molding member 40, so that the movement of the molding member 40 can be suppressed and the gap between the molding member 40 and the glass run body 21 is reduced. It can be eliminated, and the appearance can be improved.

  Further, since the groove 29a is formed at the base end portion of the outer body seal lip 29, the outer body seal lip 29 can be reliably elastically deformed in the vicinity of the groove 29a when the automobile door 1 is closed. Thus, the outer vehicle body seal lip 29 can be reliably brought into contact with the upper end of the molding member 40.

  Further, the outer side wall portion 27 may be provided at the lower end portion of the vertical plate portion 23, and the groove portion 27 c extending in the front-rear direction may be formed at the base end portion of the outer side wall portion 27. Thereby, after shaping | molding, the attachment workability | operativity of the molding member 40 can be made still more favorable, without giving a process etc. separately.

  Further, since the rigidity of the base end portion of the outer vehicle body seal lip portion 29 is lowered, the force acting on the molding member 40 in a state where the contact portion 29b of the outer vehicle body seal lip portion 29 is in contact with the molding member 40 is applied. Can be small. Thereby, since the meandering of the molding member 40 in the longitudinal direction can be suppressed, the appearance of the appearance can be further improved.
