BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a glass run arranged on a window frame of an automobile door and a method for assembling the glass run.

There are several types of doors provided on the sides of automobiles, one of which is a door having a window frame that holds the peripheral edge of the window glass. A door having this window frame is provided with a glass run for sealing between the window frame and the window glass (see, for example, Patent Document 1).

The glass run of Patent Document 1 is assembled to the window frame from the outside of the passenger compartment. The glass runs that are assembled to the window frame from the outside of the vehicle, such as the glass runs disclosed in these documents, are called hidden types that cover and hide part of the window frame from the outside of the vehicle. may be adopted from the requirements of

Further, the glass run of Patent Document 1 includes a glass run body having an insertion groove attached to a glass run mounting plate portion extending from the upper portion of the window frame toward the vehicle exterior side, and a molding assembled to the vehicle exterior side of the glass run body. ing. The molding is a member used as part of the design of the vehicle, and is generally made of a hard member such as stainless steel or aluminum, and has a shape that extends long in the vehicle front-rear direction along the glass run body. Upper and lower portions of the molding are provided with upper and lower fitting portions that are bent toward the inside of the passenger compartment, respectively.

By the way, FIG. 1 to FIG. 3. By using a relatively soft material for the rail portion of the glass run main body and forming a lip shape, the molding can be pushed into the glass run main body from the outside of the vehicle interior to the inside of the vehicle interior, that is, in the cross-sectional direction. discloses a method of assembly. However, in this structure and assembly method, the lip-shaped rail-shaped portion is easily flexed and deformed, so although it is easy to install, there is a possibility that the molding will come off the glass run main body after assembly.

Therefore, when assembling a glass run having a molding as in Patent Document 1, the rail-shaped portion provided on the exterior side of the glass run main body is made of a relatively hard material, and the molding is formed in the longitudinal direction. A method is conceivable in which the upper and lower fitting portions of the molding are fitted to the rail-shaped portions by sliding (in the longitudinal direction of the vehicle), and the molding and the glass run body are aligned in the longitudinal direction of the vehicle.

However, the upper part of the glass run body on the outside of the passenger compartment is provided with a contact part that contacts the upper part of the molding after assembly, and the contact part is made of the same soft elastomer as the glass run body. Therefore, the frictional force generated between the molding and the contact portion increases when the molding is slid during assembly. This means that a large force is required to assemble the molding, making it difficult for workers to manually assemble the molding.

In response to this, it is conceivable to reduce or eliminate the contact portion that contacts the upper part of the molding, but doing so creates a gap between the glass run body and the upper part of the molding, which is undesirable in terms of appearance. .

Therefore, as a means of assembling the molding without reducing or eliminating the contact portion, it is conceivable to introduce a machine for assembling the molding and perform assembly by machine. However, such a machine does not have general versatility, so it is extremely expensive, and it is a large-scale device that is difficult to adjust and install, making it difficult to introduce itself.

SUMMARY OF THE INVENTION The present invention has been made in view of the above points, and an object of the present invention is to enable an operator to manually assemble a molding to a glass run body without introducing a machine for assembling the molding. In addition, after assembly, the gap between the glass run body and the molding is minimized, and the external appearance is improved.

In order to achieve the above object, the first invention provides an automobile door which is assembled from the outside of the vehicle to a window frame extending to form a window opening of the automobile door, and which seals between the window frame and the window glass.

The design portion 33 is gently curved toward the outside of the passenger compartment.

An upper body-side fitting portion 23a and a lower body-side fitting portion 23b, into which the upper molding side fitting portion 31 and the lower molding side fitting portion 32 are respectively fitted, are provided on the outside of the vehicle of the glass run body 20 in the longitudinal direction. formed to extend. That is, a base portion 23c is formed on the exterior surface of the interior side plate portion 23 of the glass run body 20 so as to protrude toward the exterior side of the interior. The base portion 23c is positioned near the center in the vertical direction of the outer surface of the vehicle interior of the vehicle exterior side plate portion 23, and is continuous in the front-rear direction.

As shown in FIG. 4, the upper main body side fitting portion 23a is formed of a plate-like portion formed to protrude upward from the distal end portion of the base portion 23c in the projecting direction and extend in the front-rear direction. Between the upper body side fitting portion 23a and the exterior surface of the vehicle exterior side plate portion 23, a gap S1 wider than the thickness of the plate material forming the upper molding side fitting portion 31 of the molding 30 is formed. there is

Further, the lower main body side fitting portion 23b is formed of a plate-like portion formed so as to protrude downward from the distal end portion of the base portion 23c in the projecting direction and extend in the front-rear direction. Between the lower main body side fitting portion 23b and the vehicle exterior surface of the vehicle exterior side plate portion 23, a gap S2 wider than the thickness of the plate material forming the lower molding side fitting portion 32 of the molding 30 is formed. there is

The upper main body side fitting portion 23a and the lower main body side fitting portion 23b continuously extend from the front end portion to the rear end portion of the glass run body 20. It is a rail-shaped part that also functions as a rail that guides in the direction.

As shown in FIG. 3, the upper molding side fitting portion 31 of the molding 30 is arranged to surround the upper body side fitting portion 23a of the glass run body 20 from above. is fitted into the upper main body side fitting portion 23a. Further, the lower molding side fitting portion 32 of the molding 30 is arranged so as to surround the lower body side fitting portion 23b of the glass run body 20 from below. It fits into the side fitting portion 23b. When the upper molding side fitting portion 31 and the lower molding side fitting portion 32 are fitted to the upper body side fitting portion 23a and the lower body side fitting portion 23b, respectively, the upper molding side fitting portion 31 and the lower molding side fitting portion 31 are fitted. The shape of the joining portion 32 prevents the molding 30 from being displaced with respect to the glass run main body 20 in the vehicle interior and exterior directions and in the vertical direction.

In this embodiment, since the upper body side fitting portion 23a and the lower body side fitting portion 23b are formed integrally with the vehicle exterior side plate portion 23, the upper body side fitting portion 23a and the lower body side fitting portion 23a and the lower body side fitting portion 23b can also be constructed of a highly rigid material. Therefore, the molding 30 is removed from the glass run main body 20 in a state where the upper molding side fitting portion 31 and the lower molding side fitting portion 32 are respectively fitted with the upper body side fitting portion 23a and the lower body side fitting portion 23b. become difficult.

An upper contact portion 40 made of an elastic material is formed on the exterior side of the glass run body 20 so as to contact the upper portion of the outer surface of the molding 30 . The upper contact portion 40 is provided so as to protrude toward the outside of the passenger compartment from the surface of the base end portion of the upper seal lip 24 facing toward the outside of the passenger compartment. The upper contact portion 40 and the upper seal lip 24 are formed integrally. It is The upper contact portion 40 is formed so as to taper toward the distal end side in the projecting direction (outside the vehicle compartment), and extends continuously in the front-rear direction. The lower surface of the tip side of the upper contact part 40 contacts the molding 30 from above, thereby eliminating the gap between the upper part of the molding 30 and the upper part of the glass run body 20, and improving the external appearance.

Since the upper contact portion 40 and the upper seal lip 24 are formed integrally with each other through the thick base end portion 24a, when the upper seal lip 24 is elastically deformed in the vehicle interior and exterior direction, the upper contact portion 40 is moved to the upper seal lip 24. is slightly displaced corresponding to the amount of deformation and the direction of deformation. For example, the upper seal lip 24 has a shape that protrudes substantially upward when the left front door 1 is in the open state as described above. The position and shape of the upper contact portion 40 are set so as to contact from above. Further, when the left front door 1 is closed, the upper seal lip 24 is elastically deformed so as to fall obliquely downward on the outside of the passenger compartment. is slightly displaced toward the outside of the vehicle and downward. As a result, the lower surface of the tip side of the upper contact portion 40 contacts the molding 30 somewhat strongly from above, so that the upper contact portion 40 and the molding 30 can be brought into closer contact with each other.

A lower contact portion 41 made of an elastic material is formed on the outside of the glass run body 20 at a portion spaced downward from the upper contact portion 40 so as to come into contact with the lower portion of the outer surface of the molding 30 . The lower contact portion 41 is provided so as to protrude from the surface of the lower seal portion 27 on the outside of the passenger compartment toward the outside of the passenger compartment, and the lower contact portion 41 and the lower seal portion 27 are integrally molded. there is The lower contact portion 41 extends continuously in the front-rear direction. The lower contact part 41 comes into contact with the molding 30 from below, thereby eliminating a gap between the lower part of the molding 30 and the lower part of the glass run body 20, thereby improving the external appearance.

Since the lower contact portion 41 and the lower seal portion 27 are integrally formed and both extend downward from the base end portion 27a, when the lower seal portion 27 is elastically deformed, the lower seal portion 27 is deformed. The side contact portion 41 is displaced according to the amount and direction of deformation of the lower seal portion 27 . For example, when the window glass 4 is in the closed state as described above, the lower seal portion 27 contacts the outer surface of the window glass 4 inside the vehicle compartment, so at this time, it may be elastically deformed toward the outside of the vehicle compartment. be. As a result, the lower contact portion 41 is displaced to the outside of the passenger compartment and comes into strong contact with the molding 30 from below, so that the lower contact portion 41 and the molding 30 can be brought into close contact with each other.

A projection 23d that contacts the interior surface of the molding 30 is provided on the exterior side of the glass run body 20 so as to protrude toward the interior side of the vehicle. The protrusion 23 d contacts the interior surface of the molding 30 , so that a wide area of the exterior side plate portion 23 can be prevented from coming into contact with the molding 30 . 23 d of protrusions can be integrally formed by the vehicle exterior side board part 23. As shown in FIG.

(Coating for reducing sliding resistance)
In this embodiment, the molding 30 is attached to the glass run body 20 by sliding it in the longitudinal direction from one end. In order to do so, a structure capable of reducing the sliding resistance of the molding 30 is provided.

That is, the portion of the upper contact portion 40 that contacts the molding 30 has an elastic upper coating 40a. The upper coating 40a has a lower sliding resistance against the molding 30 than the elastic material forming the portion of the upper contact portion 40 covered by the upper coating 40a. Specifically, the portion of the upper contact portion 40 covered with the upper coating 40a is made of the same elastic material as the upper seal lip 24 and the like, but the upper coating 40a is made of olefin resin mixed with silicon. As a result, the upper seal lip 24 and the like are made of a material with a smaller coefficient of dynamic friction than an elastic material. It should be noted that the material constituting the upper coating 40a may be other than a mixture of olefinic resin and silicon.

The coefficient of dynamic friction of the upper coating 40a is preferably 0.5 or less. The dynamic friction coefficient of the upper coating 40a can be arbitrarily changed by the amount of silicon mixed. On the other hand, the coefficient of dynamic friction of the elastic material forming the portion of the upper contact portion 40 covered with the upper coating 40a is about 0.6.

Here, a method for measuring the coefficient of dynamic friction will be described. As a method for measuring the coefficient of dynamic friction, the method disclosed in Japanese Patent Application Laid-Open No. 9-123761 can be used, and the coefficient of dynamic friction is the value obtained by this measuring method. As a measuring instrument, a surface texture measuring instrument "HEIDON-14D" manufactured by Shinto Kagaku Co., Ltd. was prepared, and the dynamic friction coefficient was measured using a sheet metal watch glass. That is, as described in FIG. 3 of Japanese Patent Application Laid-Open No. 9-123761, a sheet metal watch glass is pressed against the upper surface of the sample with a load of 1 kgf, and the sheet metal watch glass and the sample are moved relative to each other at a speed of 1000 mm/min. Measure the dynamic friction coefficient by

The thickness of the upper coating 40a is set to 0.005 mm or more and 0.5 mm or less. By ensuring the thickness of the upper coating 40a to be 0.005 mm or more, the sliding resistance to the molding 30 is sufficiently reduced. In addition, by setting the thickness of the upper coating 40a to 0.5 mm or less, deterioration in flexibility of the upper contact portion 40 due to the presence of the upper coating 40a is suppressed.

The thickness of the upper coating 40a is more preferably 0.01 mm or more and 0.2 mm or less, more preferably 0.03 mm or more and 0.1 mm or less. By setting the thickness of the upper coating 40a in this manner, it is possible to sufficiently reduce the sliding resistance and maintain the flexibility of the upper contact portion 40 at the same time. Also, the upper coating 40a can be integrally extruded at the same time that the upper contact portion 40 is extruded. By integrally extruding, the thickness of the upper coating 40a can be accurately controlled. It should be noted that the upper coating 40a may be formed by pasting a sheet-like material, or by coating with a spray or brush, instead of extrusion molding.

A portion of the lower contact portion 41 that contacts the molding 30 has a lower coating 41a. is set lower than the elastic material forming the portion covered by The lower coating 41a may be made of the same material as the upper coating 40a and may have the same thickness. Also, the lower contact portion 41 is molded in the same manner as the upper coating 40a.

(Method for assembling glass run for automobile door)
Next, a method for assembling the left front door glass run 10 configured as described above will be described. Before the glass run body 20 is attached to the window frame 3, a portion (glass run upper side portion 11) extending along the frame upper side portion 3a is formed linearly. On the other hand, the molding 30 is curved in advance along the frame upper side portion 3 a of the window frame 3 .

Then, the upper body side fitting portion 23a and the lower body side fitting portion 23a of the glass run body 20 are attached to the upper molding side fitting portion 31 and the lower molding side fitting portion 32 of the molding 30 from one longitudinal end thereof. After fitting one longitudinal end of 23b, the glass run main body 20 is slid on the molding 30 in the longitudinal direction to perform a slide assembling process.

In this slide assembly process, first, the upper body side fitting portion 23 a and the lower body side of the glass run body 20 are attached to the front end portions of the upper molding side fitting portion 31 and the lower molding side fitting portion 32 of the molding 30 . The rear end portion of the side fitting portion 23b is fitted. After the upper body side fitting portion 23 a and the lower body side fitting portion 23 b are fitted to the upper molding side fitting portion 31 and the lower molding side fitting portion 32 , the glass run body 20 is rearwardly attached to the molding 30 . Slide it to the side. When the molding 30 is slid, as described above, the molding 30 is curved, but the glass run upper side portion 11 of the glass run main body 20 is straight. The upper contact portion 40 of 20 makes a strong contact. Further, the lower contact portion 41 of the glass run body 20 may come into contact with the lower molding-side fitting portion 32 of the molding 30 .

At this time, since the portion of the upper contact portion 40 that contacts the molding 30 is covered with the upper coating 40a having a lower dynamic friction coefficient with respect to the molding 30 than the upper contact portion 40, the upper portion of the molding 30 and the upper contact portion 40 are separated. The sliding resistance between In addition, since the portion of the lower contact portion 41 that contacts the molding 30 is covered with the lower coating 41a that has a lower dynamic friction coefficient with respect to the molding 30 than the lower contact portion 41, the lower portion of the molding 30 is in contact with the lower side. The sliding resistance between the portion 41 is also reduced. Therefore, the operator can easily assemble the glass run main body 20 to the molding 30 by hand, thus eliminating the need to introduce a molding assembling machine. When the front end portion of the molding 30 reaches the front end portion of the glass run upper side portion 11 of the glass run main body 20, the sliding operation is stopped. By assembling the glass run main body 20 to the molding 30 as described above, the assembly work of the left front door glass run 10 is completed.

Since the molding 30 is curved upward, the upper portion of the molding 30 contacts the glass run body 20 more strongly than the lower portion. Therefore, the glass run body 20 may be provided with at least the upper coating 40a, and the lower coating 41a may be omitted.

Also, in the slide assembly process, the method of sliding the glass run main body 20 with respect to the molding 30 has been described, but the reverse method of sliding the molding 30 with respect to the glass run main body 20 may be used.

(When using a glass run for automobile doors)
When the left front door glass run 10 is attached to the left front door 1, the left front door glass run 10 is attached to the glass run attachment plate portion 8 of the window frame 3, and at the same time, the lower engaging projection of the upper plate portion 21 is mounted. 21a and the upper engaging projection 22a of the lower plate portion 22 contact the upper surface side and the lower surface side of the glass run mounting plate portion 8, respectively. When the left front door glass run 10 is attached in this manner, the bending elastic modulus of the upper plate portion 21, the lower plate portion 22, and the exterior side plate portion 23 is set to 2000 MPa or more and 5000 MPa or less. The fixing strength of the glass run body 20 to the portion 8 is increased.

After that, when the left front door 1 is closed, the upper seal lip 24 and the inner seal lip 25 of the glass run body 20 come into contact with the vehicle body 100 and are elastically deformed so as to bend toward the outside of the passenger compartment. 100 can be sealed by an upper sealing lip 24 and an inner sealing lip 25 . At this time, since the upper contact portion 40 is provided on the outside of the passenger compartment of the thick base end portion 24a of the upper seal lip 24, the bending deformation of the upper seal lip 24 also displaces the upper contact portion 40 slightly toward the outside of the passenger compartment. As a result, the upper contact portion 40 comes into contact with the upper portion of the molding 30 on the outer surface of the passenger compartment. Therefore, there is no gap between the upper contact portion 40 and the molding 30, and the external appearance can be improved.
