Description

[Technical Field]

[0001] The present disclosure relates to a glass run for an automobile door that is assembled to a window frame of the automobile door. [Background technology]

[0002] For example, Patent Document 1 discloses a glass run that is attached to a window frame from the exterior side of the vehicle. The glass run in Patent Document 1 includes an upper edge of the glass run that extends in the longitudinal direction along the side edge of the roof of the vehicle, and a molding that is attached to the exterior side of the glass run upper edge. On the exterior side of the glass run upper edge, a fitting portion into which the molding fits is formed in the shape of a rail that is continuous in the longitudinal direction. Meanwhile, a terminal member is fixed to the rear end of the molding. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Publication No. 2023-101051 Summary of the Invention [Problem to be solved by the invention]

[0004] However, the fitting portion provided on the upper edge of the glass run in Patent Document 1 is continuous in the front-to-rear direction, but does not reach the installation position of the terminal member, so the terminal member cannot be fitted into the fitting portion. As a result, the terminal member cannot be positioned by the fitting portion, and as a result, there is a risk that the terminal member side of the molding will be displaced in the vertical direction from the intended position.

[0005] This will be explained in detail with reference to Figures 9 and 10. Figure 9 is a right side view of an automobile 100, showing a conventional glass run 102 attached to a window frame 101 of a rear door 100. A rear door molding 102a extending in the longitudinal direction of the vehicle is attached to the exterior side of the glass run 102. A rear side glass 104 is fixed to the vehicle body behind the rear door 100. A rear molding 106 is provided along the upper edge of the rear side glass 104. A garnish 105 is attached to the rear edge 101a of the window frame 101.

[0006] 10 is an enlarged view of the area within frame A in FIG. 9. A terminal member 102b is fixed to the rear end of the rear door molding 102a, but in the structure disclosed in Patent Document 1, the terminal member 102b cannot be positioned by a fitting, so that when the window glass is fully closed, for example, the lower portion of the rear door molding 102a may be displaced toward the outside of the vehicle and lift off from the main body of the glass run. If the lower portion of the rear door molding 102a lifts off, the terminal member side of the rear door molding 102a will be displaced upward from its normal position (shown by a virtual line).

[0007] On the other hand, the rear molding 106 is fixed to the vehicle body, and the front end of the rear molding 106 is positioned so that it is at the same height as the rear end of the rear door molding 102a in the correct position, so a step will be created between it and the rear end of the rear door molding 102a that has shifted upward, which will result in a deterioration in the external appearance of the vehicle.

[0008] The present disclosure has been made in consideration of such points, and its purpose is to improve the external appearance of the vehicle by preventing the end of the molding from shifting vertically from its correct position. [Means for solving the problem]

[0009] To achieve the above object, one aspect of the present disclosure can be premised on a glass run for an automobile door that is attached from the exterior of the vehicle to a window frame that extends to form a window opening of the automobile door and seals the gap between the window frame and the windshield. The glass run for an automobile door includes a glass run body that is attached to a glass run mounting plate that extends from the upper part of the window frame to the exterior of the vehicle and has a glass run upper edge that extends in the fore-and-aft direction of the vehicle, and a molding that is attached to the exterior of the glass run upper edge and extends in the fore-and-aft direction of the vehicle. The molding has upper and lower molding-side fitting portions that extend in the vehicle front-to-rear direction and fit onto the exterior side of the glass run upper edge portion, a body-side fitting portion that extends in the vehicle front-to-rear direction and into which the upper and lower molding-side fitting portions fit onto the exterior side of the glass run upper edge portion, an end cap having a locking portion that protrudes toward the other end is fixed to one end of the molding in the vehicle front-to-rear direction, an insertion hole is opened at one end of the glass run upper edge portion in the vehicle front-to-rear direction, and the locking portion of the end cap is inserted into the insertion hole and locks onto the glass run upper edge portion, and the end cap has a fixing plate that extends along the interior surface of the molding and is fixed to the molding, and a groove is formed in the fixing plate so as to fit onto the exterior side of the body-side fitting portion of the glass run upper edge portion.

[0010] With this configuration, when assembling the glass run main body to the molding, the main body side fitting portion on the outside of the vehicle of the upper edge of the glass run is fitted into the upper and lower molding side fitting portions of the molding from its end, and then the upper edge of the glass run is moved relative to the molding in the fore-and-aft direction of the vehicle, thereby easily assembling the molding to the upper edge of the glass run.

[0011] When the molding is attached to the upper edge of the glass run, the locking portion of the end cap is inserted into the insertion hole in the upper edge of the glass run and locked to the upper edge of the glass run. In this state, the fixing plate of the end cap is fixed to the molding and fits into the outer side of the upper edge of the glass run, so that the one end of the molding in the front-to-rear direction of the vehicle is positioned on the upper edge of the glass run via the end cap. This makes it difficult for the one end of the molding in the front-to-rear direction of the vehicle to shift upward from its correct position, even if it is pushed up by the window glass when the window is fully closed.

[0012] The main body-side fitting portion may extend to reach one end of the upper edge portion of the glass run in the vehicle longitudinal direction and may have an upper fitting portion that protrudes upward and a lower fitting portion that protrudes downward. The fixing plate may be formed with an upper groove that fits into the upper fitting portion and a lower groove that fits into the lower fitting portion. This allows the upper and lower fitting portions to be easily fitted together by inserting them into the upper and lower grooves during assembly.

[0013] The fixing plate may have a shape extending in the up-down direction and the fore-and-aft direction of the vehicle. The upper groove may be formed by an upper portion of the fixing plate, an upper protrusion protruding upward from an upper portion of the fixing plate, and an upper inner protrusion protruding downward from the interior side of the upper protrusion. The lower groove may be formed by a lower portion of the fixing plate, a lower protrusion protruding downward from a lower portion of the fixing plate, and a lower inner protrusion protruding downward from the interior side of the lower protrusion.

[0014] The upper and lower fitting portions may be integrally formed with a base portion that protrudes from the upper edge portion of the glass run toward the exterior of the vehicle. With the upper groove and the lower groove of the fixing plate fitted into the upper fitting portion and the lower fitting portion, respectively, a gap is formed between the lower end of the upper inner protrusion and the upper surface of the base, while the upper end of the lower inner protrusion may abut against the lower surface of the base.

[0015] An upper inclined surface is formed on the other side of the upper inner protrusion in the fore-and-aft direction of the vehicle, which is inclined so that it becomes higher as it approaches the other end, and a lower inclined surface is formed on the other side of the lower inner protrusion in the fore-and-aft direction of the vehicle, which is inclined so that it becomes lower as it approaches the other end, so that it is less likely to get caught during assembly.

[0016] A separate resin part may be provided between the design portion of the molding and the upper edge of the glass run. In this case, an upper bent portion is formed above the design portion of the molding so as to be bent toward the vehicle interior and bent downward, and a lower bent portion is formed below the design portion of the molding so as to be bent toward the vehicle interior and bent upward. Furthermore, an upper resin fitting portion that fits inside the upper bent portion may be formed at an upper part of the resin part, and a lower resin fitting portion that fits inside the lower bent portion may be formed at a lower part of the resin part. [Effects of the Invention]

[0017] As explained above, an end cap is fixed to one end in the vehicle's fore-and-aft direction of the molding that is assembled to the vehicle's exterior side of the upper edge of the glass run, and this end cap is fitted to the vehicle's exterior side of the upper edge of the glass run, so that the one end in the vehicle's fore-and-aft direction of the molding is prevented from shifting up and down from its correct position, improving the external appearance of the vehicle.

DETAILED DESCRIPTION OF THE INVENTION

[0019] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. Note that the following description of the preferred embodiments is merely exemplary in nature and is not intended to limit the present invention, its applications, or its uses.

[0020] FIG. 1 is a right side view of an automobile 200 equipped with an automobile door glass run 1 according to an embodiment of the present invention. A right front door 300 and a right rear door 100 are provided on the right side of the automobile 200. Although not shown, the left front door is provided bilaterally symmetrically with the right front door 300, and the left rear door is provided bilaterally symmetrically with the right rear door 100. The automobile door glass run 1 of this embodiment is provided on the right rear door 100, but the present invention can also be applied to glass runs on the right front door 300, left rear door, left front door, etc. In the description of this embodiment, the front side of the vehicle will be simply referred to as the "front" and the rear side of the vehicle will be simply referred to as the "rear."

[0021] 1, the right rear door 100 has a door body 120 that constitutes approximately the lower half of the right rear door 100, and a window frame 130 that constitutes approximately the upper half. Although not shown, the front end of the door body 120 is attached to a pillar of the vehicle body via a hinge that has a rotation shaft that extends in the vertical direction. The interior of the door body 120 can accommodate a window glass 121 that can be raised and lowered, a lifting device (not shown) for raising and lowering the window glass 121, and the like.

[0022] The window frame 130 functions as a sash that holds the peripheral edge of the window glass 121, and extends to form a window opening 122. The window opening 122 formed by the window frame 130 is opened and closed by the window glass 121. The window frame 130 of this embodiment is formed by combining an outer panel 131 and an inner panel 132 that are formed by press-forming steel plates or the like, as shown in Fig. 3. The window frame 130 may also be formed by roll forming, for example.

[0023] As shown in FIG. 1, the window frame 130 is composed of a frame upper edge portion 130a, a frame rear edge portion 130b, and a frame front edge portion 130c. The frame upper edge portion 130a is gently curved so that it is positioned lower as it moves toward the rear. The frame rear edge portion 130b extends upward from the rear portion of the upper edge of the door body 120. The window frame 130 is composed by connecting the upper end of the frame rear edge portion 130b to the rear end of the frame upper edge portion 130a. The frame front edge portion 130c extends upward from the front portion of the upper edge of the door body 120. The window frame 130 is composed by connecting the upper end of the frame front edge portion 130c to the front end of the frame upper edge portion 130a.

[0024] The shape of the window frame 130 is not limited to the shape shown in the figure, but may be a shape that is curved upward overall, and the position of the curved portion, the inclination angle of the frame upper edge portion 130a, and the curvature can also be set arbitrarily to correspond to the roof shape of the vehicle body.

[0025] As shown in FIG. 3 , a glass run mounting plate 135 extending toward the vehicle exterior is formed on the frame upper edge portion 130a of the window frame 130. The glass run mounting plate 135 is made up of the vehicle exterior portions of the outer panel 131 and the inner panel 132. That is, the vehicle exterior portion of the outer panel 131 extends substantially horizontally and continuously in the front-to-rear direction. The vehicle exterior portion of the inner panel 132 also extends substantially horizontally and continuously in the front-to-rear direction. The glass run mounting plate 135 is formed by overlapping the upper surface of the vehicle exterior portion of the outer panel 131 with the lower surface of the vehicle exterior portion of the inner panel 132. Note that the glass run mounting plate 135 may be formed by both the outer panel 131 and the inner panel 132, or it may be formed by one of the outer panel 131 and the inner panel 132.

[0026] A weatherstrip 400 is provided on the upper surface of the frame upper side portion 130a. The weatherstrip 400 is fixed to the upper surface of the frame upper side portion 130a on the vehicle interior side.

[0027] 1, a garnish 105 made of, for example, a resin plate is attached to the exterior side of the frame rear edge 130b of the window frame 130. The garnish 105 extends vertically along the exterior surface of the vehicle cabin of the frame rear edge 130b and is a member that covers the exterior surface of the vehicle cabin. The upper end of the garnish 105 reaches the rear end of the frame upper edge 130a.

[0028] A rear side window 104 is fixed to the vehicle body behind the rear door 100. The rear side window 104 cannot be raised or lowered. A rear molding 106 is provided along the upper edge of the rear side window 104.

[0029] (Configuration of glass runs for automobile doors) As shown in FIGS. 1 to 3, the automobile door glass run 1 is attached to the frame upper side 130a of the window frame 130 from the vehicle exterior side, and functions as a sealant for sealing between the window frame 130 and the window glass 121.

[0030] The glass run 1 for an automobile door comprises a glass run upper edge portion 11, a glass run front vertical edge portion 12, and a glass run rear vertical edge portion 13. The glass run upper edge portion 11, the glass run front vertical edge portion 12, and the glass run rear vertical edge portion 13 are integrated together. The glass run upper edge portion 11 extends in the front-to-rear direction along the frame upper edge portion 130a, which is the upper part of the window frame 130, and is curved along the frame upper edge portion 130a when assembled to the glass run mounting plate 135, and is positioned so that it is positioned lower as it approaches the rear end.

[0031] The glass run front vertical side portion 12 extends downward from a position rearward of the front end portion of the glass run upper side portion 11. The glass run rear vertical side portion 13 extends downward from a position rearward of the glass run upper side portion 11 and forward of the rear end portion of the glass run upper side portion 11. Therefore, the rear end portion of the glass run upper side portion 11 is located rearward of the upper end portion of the glass run rear vertical side portion 13.

[0032] The lower sides of the front vertical side portion 12 and the rear vertical side portion 13 of the glass run extend until they reach the inside of the door body 120, and these front vertical side portion 12 and rear vertical side portion 13 of the glass run guide the front and rear parts of the windshield 121 in the vertical direction, respectively.

[0033] The glass run upper edge portion 11 of the right-side rear door glass run 1 comprises a glass run main body 20 having an insertion groove 14 into which a glass run mounting plate 135 is inserted, and a molding 30 that is attached to the exterior side of the vehicle of the glass run main body 20 and extends in the front-to-rear direction. The molding 30 is attached only to the glass run main body 20 that constitutes the glass run upper edge portion 11, and is not attached to the glass run front vertical edge portion 12 or the glass run rear vertical edge portion 13. This molding 30 can also be called a sash molding because it extends along the frame upper edge portion 130a.

[0034] The glass run body 20 has an upper plate 21 extending along the upper surface of the glass run mounting plate 135, a lower plate 22 extending along the lower surface of the glass run mounting plate 135, and an exterior plate 23 extending in the vertical direction from the exterior end of the upper plate 21 to the exterior end of the lower plate 22. The upper plate 21, lower plate 22 and exterior plate 23 are integrally molded.

[0035] An insertion groove 14 is formed between the upper plate 21 and the lower plate 22. The insertion groove 14 opens between the vehicle interior end of the upper plate 21 and the vehicle interior end of the lower plate 22, and extends in the front-to-rear direction. The bottom of the insertion groove 14 is formed by the vehicle exterior plate 23. The depth of the insertion groove 14 and the dimension in the vehicle interior / exterior direction (left-right dimension) of the glass run mounting plate 135 are set so that when the glass run upper edge portion 11 of the glass run main body 20 is attached to the glass run mounting plate 135, the vehicle exterior end of the glass run mounting plate 135 reaches near the bottom of the insertion groove 14.

[0036] The upper plate 21, the lower plate 22, and the exterior panel 23 can be made of, for example, a hard resin (e.g., polypropylene mixed with talc or glass fiber), but the materials are not limited to these, and other materials such as metal or various composite materials can also be used. By making the upper plate 21, the lower plate 22, and the exterior panel 23 out of the above-mentioned high-rigidity materials, the rigidity of the upper plate 21, the lower plate 22, and the exterior panel 23 is increased, and in particular, opening of the upper plate 21 and the lower plate 22 can be suppressed. As a result, with the glass run main body 20 attached to the glass run mounting plate 135, the glass run mounting plate 135 can be firmly sandwiched between the upper plate 21 and the lower plate 22 in the vertical direction, making it difficult for the glass run main body 20 to come off the glass run mounting plate 135.

[0037] An upper engagement protrusion 21a that protrudes downward is formed on the lower surface of the upper plate 21. The lower end of the upper engagement protrusion 21a is formed so as to abut against the upper surface of the glass run mounting plate 135. The upper surface of the lower plate 22 is formed so as to abut against the lower surface of the glass run mounting plate 135.

[0038] An outer body seal lip 24 is provided to protrude upward from the upper portion of the glass run body 20 on the outer side of the vehicle. The base end of the outer body seal lip 24 is integrated with the outer side portion of the upper surface of the upper plate 21.

[0039] An inner body seal lip 25 is provided at the upper part of the interior side of the glass run body 20 so as to protrude obliquely upward toward the exterior side of the vehicle. The base end of the inner body seal lip 25 is integrated with the interior side portion of the upper surface of the upper plate 21.

[0040] An inner seal lip 26 is provided so as to protrude downward from the end of the upper plate 21 facing the vehicle interior. The inner seal lip 26 is fixed to and integrated with the end of the upper plate 21 facing the vehicle interior. The lower end of the inner seal lip 26 is adapted to elastically contact the upper surface of the glass run mounting plate 135.

[0041] A lower seal portion 27 is provided at the lower part of the exterior side of the glass run body 20 so as to protrude downward. A base end 27a of the lower seal portion 27 is integrated with the exterior side portion of the underside of the lower plate 22. The lower part of the lower seal portion 27 is bent toward the interior side of the vehicle. An outer glass seal lip 27b is provided at the lower part of this lower seal portion 27, protruding upward as it approaches the interior side of the vehicle, and is configured to come into contact with the exterior surface of the window glass 121 in the closed state.

[0042] An inner seal portion 28 is provided at the lower part of the glass run body 20 on the interior side of the vehicle so as to protrude downward. A base end 28a of the inner seal portion 28 is integrated with the end surface of the lower panel 22 on the interior side of the vehicle. A lower part of the inner seal portion 28 is bent toward the interior side of the vehicle. This lower part of the inner seal portion 28 is adapted to contact the window frame 130. More specifically, the tip protruding portion of the downward flange 136 of the window frame 130 is covered by a molding lip 28c that folds back from the lower end of the inner seal portion 28 and protrudes upward. The inner seal portion 28 is also provided with an inner glass seal lip 28b that protrudes upward as it moves toward the exterior of the vehicle, and is adapted to contact the interior surface of the window glass 121 when closed.

[0043] An intermediate seal lip 29 is provided on the lower surface of the lower plate 22 between the base end 27a of the lower seal portion 27 and the base end 28a of the inner seal portion 28. The base end of the intermediate seal lip 29 is integrated with a middle portion of the lower surface of the lower plate 22 in the interior / exterior direction. The intermediate seal lip 29 is formed to extend obliquely downward toward the exterior of the vehicle, and is configured to come into contact with the upper end of the window glass 121 in the closed state.

[0044] The outer body seal lip 24, the inner body seal lip 25, the inner seal lip 26, the lower seal portion 27, the inner seal portion 28, and the intermediate seal lip 29 are made of a material that is softer and more elastically deformable than the components (the upper panel 21, the lower panel 22, and the outer panel 23) made of the high-rigidity material. The outer body seal lip 24, the inner body seal lip 25, the inner seal lip 26, the lower seal portion 27, the inner seal portion 28, and the intermediate seal lip 29 can be made of elastic materials such as EPDM (ethylene propylene diene rubber) and TPO (olefin-based thermoplastic elastomer). The EPDM and TPO may be foamed or non-foamed. When the high-rigidity material is a hard resin such as polypropylene, it is preferable to use TPO.

[0045] The outer body seal lip 24, the inner body seal lip 25, the inner seal lip 26, the lower seal portion 27, the inner seal portion 28 and the intermediate seal lip 29, together with the upper plate 21, the lower plate 22 and the outer side plate 23, are parts that make up the glass run main body 20.

[0046] The molding 30 is a component used as part of the vehicle design, and generally comprises a design portion 33 made of a hard material such as stainless steel or aluminum, and a resin component 35 that is separate from the design portion 33. In this embodiment, the design portion 33 that constitutes the exterior design is made of a stainless steel plate. The resin component 35 is a component provided between the design portion 33 and the glass run upper edge portion 11. The molding 30 has a shape that extends long in the front-to-rear direction along the glass run main body 20, with the front end of the molding 30 located near the front end of the frame upper edge portion 130a of the window frame 130, and the rear end of the molding 30 located near the rear end of the frame upper edge portion 130a of the window frame 130.

[0047] An upper retaining portion 31 and a lower retaining portion 32 are formed on the upper and lower portions of the design portion 33 of the molding 30, extending in the front-rear direction and respectively holding the upper and lower portions of the resin part 35. The upper retaining portion 31 is formed by bending the plate material constituting the design portion 33 toward the interior of the vehicle and bending it downward, resulting in a shape that opens downward. The lower retaining portion 32 is formed by bending the plate material constituting the design portion 33 toward the interior of the vehicle and bending it upward, resulting in a shape that opens upward. An upper resin fitting portion 35a that fits inside the upper holding portion 31 is formed on the upper portion of the resin part 35. Furthermore, a lower resin fitting portion 35b that fits inside the lower holding portion 32 is formed on the lower portion of the resin part 35.

[0048] The portion of the design portion 33 between the upper holding portion 31 and the lower holding portion 32 is a main body portion 35c that extends in the vertical and longitudinal directions and is gently curved toward the exterior of the vehicle.

[0049] Upper and lower molding-side fitting portions 36, 37 that fit onto the exterior side of the glass run body 20 are formed on the resin part 35 so as to extend in the front-to-rear direction. The upper molding-side fitting portion 36 is formed so as to protrude from the upper side of the resin part 35 toward the interior side of the vehicle and bend downward, forming an upper groove 35A that opens downward. The lower molding-side fitting portion 37 is formed so as to protrude from the lower side of the resin part 35 toward the interior side of the vehicle and bend upward, forming a lower groove 35B that opens upward.

[0050] When the upper groove 35A and the lower groove 35B of the resin part 35 are fitted into the upper body fitting portion 23a and the lower body fitting portion 23b, respectively, the upper end of the upper groove 35A abuts against the upper surface of the upper body fitting portion 23a, and a gap S1 is formed between the lower end of the lower groove 35B and the lower surface of the lower body fitting portion 23b. In other words, the lower end of the lower groove 35B and the lower surface of the lower body fitting portion 23b are not in contact with each other.

[0051] Furthermore, when the upper groove 35A and the lower groove 35B of the resin part 35 are fitted into the upper body side fitting portion 23a and the lower body side fitting portion 23b, respectively, the lower end of the upper molding side fitting portion 36 abuts against the upper surface of the base 23c, and a gap S2 is formed between the upper end of the lower molding side fitting portion 37 and the lower surface of the base 23c.

[0052] That is, the upper end of the lower molding-side fitting portion 37 and the underside of the base 23c are not in contact with each other. To achieve this relationship, the root position and protrusion amount of the upper molding-side fitting portion 36 and the root position and protrusion amount of the lower molding-side fitting portion 37 are set relative to the protrusion amounts of the upper main body-side fitting portion 23a, the lower main body-side fitting portion 23b, and the thickness of the base 23c in the vertical direction. This relationship makes it easier to slide and assemble the molding 30 and the resin part 35 to the exterior side of the upper edge of the glass run.

[0053] 4 to 7, an end cap 40 is fixed to the rear end portion (one end portion in the vehicle longitudinal direction) of the molding 30 as a positioning member for positioning the molding 30 with respect to the glass run upper edge portion 11. The end cap 40 is a resin part formed so as to cover the rear end surface of the molding 30 from behind.

[0054] 3, an upper body-side fitting portion 23a and a lower body-side fitting portion 23b, into which the upper molding-side fitting portion 36 and the lower molding-side fitting portion 37 respectively fit, are formed on the vehicle exterior side of the glass run upper edge portion 11 of the glass run body 20 so as to extend in the front-to-rear direction. That is, a base portion 23c is formed on the exterior surface of the vehicle compartment of the exterior panel 23 of the glass run body 20 so as to protrude toward the exterior of the vehicle. This base portion 23c is positioned near the center in the up-down direction of the exterior surface of the vehicle compartment of the exterior panel 23 and is continuous in the front-to-rear direction.

[0055] The upper body fitting portion 23a is configured as a plate-like portion formed to protrude upward from the tip of the protruding direction of the base portion 23c and extend in the front-rear direction. A gap larger than the thickness of the plate material constituting the upper molding fitting portion 36 of the molding 30 is formed between the interior surface of the upper body fitting portion 23a and the exterior surface of the exterior panel 23.

[0056] The lower main body fitting portion 23b is formed as a plate-like portion that projects downward from the tip of the base portion 23c in the protruding direction and extends in the front-rear direction. A gap that is larger than the thickness of the plate that forms the lower molding fitting portion 37 of the molding 30 is formed between the interior surface of the lower main body fitting portion 23b and the exterior surface of the exterior panel 23.

[0057] The upper body side fitting portion 23a and the lower body side fitting portion 23b extend continuously from the front end to the rear end of the glass run body 20, and are rail-like portions that also function as rails to guide the molding 30 (separate resin parts 35 and end cap 40) in the forward and backward directions when assembling the molding 30 (separate resin parts 35 and end cap 40) described below.

[0058] The upper molding-side fitting portion 36 of the molding 30 (separate resin part 35) is arranged to surround the upper body-side fitting portion 23a of the glass run main body 20 from above, and in this state, the upper molding-side fitting portion 36 fits into the upper body-side fitting portion 23a. Furthermore, the lower molding-side fitting portion 37 of the molding 30 (separate resin part 35) is arranged to surround the lower body-side fitting portion 23b of the glass run main body 20 from below, and in this state, the lower molding-side fitting portion 37 fits into the lower body-side fitting portion 23b. When the upper molding-side fitting portion 36 and the lower molding-side fitting portion 37 fit into the upper body-side fitting portion 23a and the lower body-side fitting portion 23b, respectively, the shapes of the upper molding-side fitting portion 36 and the lower molding-side fitting portion 37 make it difficult for the molding 30 (separate resin part 35) to displace in the interior / exterior and up / down directions relative to the glass run main body 20.

[0059] 4 to 7, the end cap 40 has a cover plate 41, a fixing plate 42, and a locking portion 43, and the cover plate 41, fixing plate 42, and locking portion 43 are integrally molded. The cover plate 41 extends in the vertical direction so as to cover the rear end surface of the molding 30. The upper end of the cover plate 41 is located at the same height as the upper end of the molding 30, and the lower end of the cover plate 41 is located at the same height as the lower end of the molding 30. In other words, the shape and size of the cover 41 are set so that the rear end surface of the molding 30 is not visible when the molding 30 with the end cap 40 fixed is viewed from its rear end.

[0060] The fixing plate 42 extends in the up-down and front-rear directions along the interior surface of the decorative portion 33 of the molding 30, is supported so as to be slidable in the front-rear direction, and is fixed to the molding 30. An upper protrusion 42a provided at the upper end of the fixing plate 42 reaches the interior of the upper holding portion 31, which supports the upper protrusion 42a in the thickness direction (interior-exterior direction of the vehicle). A lower protrusion 42c provided at the lower end of the fixing plate 42 reaches the interior of the lower holding portion 32, which supports the lower protrusion 42c in the thickness direction (interior-exterior direction of the vehicle). In other words, the upper protrusion 42a and the lower protrusion 42c of the fixing plate 42 are supported by the upper and lower parts of the molding 30 and are slidable in the front-rear direction.

[0061] Then, after the front end of the end cap 40 is assembled and positioned while sliding forward from the rear end of the molding 30, the upper holding portion 31 and the lower holding portion 32 of the molding 30 are crimped (tightened) to prevent movement in the front-to-rear direction, thereby preventing movement in the interior / exterior direction of the vehicle and in the up-and-down direction. Since a conventionally known method can be used for crimping, a detailed description will be omitted.

[0062] The locking portion 43 is integrally formed on the interior side of the cover plate 41. The locking portion 43 is formed as a protruding piece that protrudes from the cover plate 41 toward the front end of the molding 30. The length of the locking portion 43 in the front-rear direction is set to be shorter than the length of the fixing plate 42 in the front-rear direction. In addition, the locking portion 43 is spaced away from the interior surface of the fixing plate 42 toward the interior of the vehicle, and a predetermined gap S4 is formed between the locking portion 43 and the fixing plate 42.

[0063] 6 shows a cross section of the rear portion of the glass run upper edge portion 11. The rear portion of the glass run upper edge portion 11 has an outer vertical plate 55 that is disposed on the exterior side of the vehicle and extends in the vertical direction, and an inner vertical plate 56 that extends to cover the outer vertical plate 55 from the interior side of the vehicle.

[0064] As shown in Figure 7, an insertion hole 58 is formed in the rear end (one end in the vehicle longitudinal direction) of the glass run upper edge portion 11, into which the locking portion 43 of the end cap 40 fixed to the molding 30 is inserted. The insertion hole 58 is formed between the vehicle exterior panel 23 and the inner vertical panel 56, and the locking portion 43 inserted into the insertion hole 58 is accommodated in a storage space R defined by the vehicle exterior panel 23 and the inner vertical panel 56. The dimension of the storage space R in the interior / exterior direction of the vehicle is set to be larger than the dimension of the locking portion 43 in the interior / exterior direction of the vehicle.

[0065] As shown in FIG. 6 , the fixing plate 42 is formed to fit onto the exterior side of the glass run upper edge portion 11. That is, the fixing plate 42 is formed with an upper groove 42A that fits into the upper main body fitting portion 23a and a lower groove 42B that fits into the lower main body fitting portion 23b. The upper groove 42A is a generally U-shaped portion that opens downward and is formed by an upper portion of the fixing plate 42, an upper protrusion 42a that protrudes upward from the top of the fixing plate 42, and an upper inner protrusion 42b that protrudes downward from the interior side of the upper protrusion 42a. The upper protrusion 42a is a portion that is supported by the upper holding portion 31 of the molding 30.

[0066] The lower groove 42B is a generally U-shaped portion that opens upward and is formed by a lower portion of the fixing plate 42, a lower protruding portion 42c that protrudes downward from the lower portion of the fixing plate 42, and a lower inner protruding portion 42d that protrudes upward from the vehicle inner side of the lower protruding portion 42c. The lower protruding portion 42c is a portion that is supported by the lower holding portion 32 of the molding 30.

[0067] When the upper groove 42A and the lower groove 42B of the fixing plate 42 are fitted into the upper body-side fitting portion 23a and the lower body-side fitting portion 23b, respectively, a gap S3 is formed between the lower end of the upper inner protrusion 42b and the upper surface of the base 23c. That is, the lower end of the upper inner protrusion 42b is not in contact with the upper surface of the base 23c. Furthermore, when the upper groove 42A and the lower groove 42B of the fixing plate 42 are fitted into the upper body-side fitting portion 23a and the lower body-side fitting portion 23b, respectively, the upper end of the lower inner protrusion 42d abuts against the lower surface of the base 23c. To achieve this relationship, the root position and protrusion amount of the upper inner protrusion portion 42b and the root position and protrusion amount of the lower inner protrusion portion 42d are set relative to the protrusion amount of the upper main body side fitting portion 23a, the protrusion amount of the lower main body side fitting portion 23b, and the vertical thickness of the base portion 23c.

[0068] 5, an upper inclined surface 42e is formed on the front side (the other side in the vehicle front-rear direction) of the upper inner protrusion 42b, which is inclined so as to become higher toward the front end. Furthermore, a lower inclined surface 42f is formed on the front side of the lower inner protrusion 42d, which is inclined so as to become lower toward the front end. This makes it less likely that the front ends of the upper inner protrusion 42b and the lower inner protrusion 42d will get caught on the rear ends of the upper main body side fitting portion 23a and the lower main body side fitting portion 23b in the initial stage of inserting and fitting the upper grooves 42A and the lower grooves 42B into the upper main body side fitting portion 23a and the lower main body side fitting portion 23b.

[0069] 5 and 6, an upper abutment portion 42g that protrudes toward the vehicle interior is provided in the middle of the interior side of the upper inner protrusion 42b. The amount of protrusion of the upper abutment portion 42g is set so that when the end cap 40 is attached to the molding 30 and the upper abutment portion 42g is attached to the main body-side fitting portion K (23a, 23b) of the glass run upper edge portion 11, the upper abutment portion 42g will abut against the exterior surface of the exterior panel 23.

[0070] At this time, the exterior surface of the upper inner protrusion 42b is set to abut against the interior surface of the upper main body fitting portion 23a. A lower abutment portion 42h that protrudes toward the interior of the vehicle is provided in the middle of the interior surface of the lower inner protrusion 42d. The amount of protrusion of the lower abutment portion 42h is set so that the lower abutment portion 42h abuts against the exterior surface of the exterior panel 23 when the end cap 40 is attached to the molding 30 and the molding 30 is attached to the main body fitting portion K (23a, 23b) of the glass run upper edge portion 11.

[0071] At this time, the outer surface of the lower inner protrusion 42d is set to abut against the inner surface of the lower main body fitting portion 23b. By setting it in this manner, when the end cap 40 is attached to the molding 30 and then attached to the main body fitting portion K (23a, 23b) of the glass run upper edge portion 11, the molding 30 and the end cap 40 can be positioned and fixed in the vehicle interior / exterior directions relative to the glass run upper edge portion 11.

[0072] FIG. 8 shows the rear vertical side portion 13 of the glass run. The rear vertical side portion 13 of the glass run has an outer wall 13a located on the outer side of the vehicle, an inner wall 13b located on the inner side of the vehicle, and a rear wall 13c located on the rear side. The rear vertical side portion 13 of the glass run is adapted to be assembled to the frame rear side portion 130b. The outer wall 13a is provided with an outer lip 13d, which comes into sliding contact with the outer surface of the windshield 121. The inner wall 13b is provided with an inner lip 13e, which comes into sliding contact with the inner surface of the windshield 121.

[0073] (Method of assembling glass runs for automobile doors) Next, a method for assembling the glass run 1 for an automobile door configured as described above will be described. As shown in Figs. 1 to 8, the glass run upper edge portion 11 of the glass run main body 20 is formed in a straight line before being attached to the glass run mounting plate 135. The end cap 40 is slid onto the rear end of the molding 30 in advance, and then fixed by crimping. In addition, a resin part 35 is attached to the design portion 33 of the molding 30.

[0074] Then, the rear ends of the upper body-side fitting portion 23a and the lower body-side fitting portion 23b of the glass run main body 20 are fitted into the upper and lower molding-side fitting portions 36, 37 of the molding 30 from its front end, and then the molding 30 is slid longitudinally relative to the glass run main body 20 to perform sliding assembly. When the front end of the molding 30 reaches the front end of the glass run upper edge portion 11 of the glass run main body 20, the sliding operation is stopped.

[0075] Before the front end of the molding 30 reaches the front end of the glass run upper edge portion 11 of the glass run main body 20, the upper groove 42A and the lower groove 42B of the fixing plate 42 of the end cap 40 are inserted from the rear end portions of the upper body-side fitting portion 23a and the lower body-side fitting portion 23b of the glass run main body 20. At this time, since the upper inclined surface 42e and the lower inclined surface 42f are formed, the front end portions of the upper inner protrusion 42b and the lower inner protrusion 42d are less likely to get caught on the rear end portions of the upper body-side fitting portion 23a and the lower body-side fitting portion 23b, allowing for smooth assembly.

[0076] Just before the front end of the molding 30 reaches the front end of the glass run upper edge portion 11 of the glass run main body 20, the locking portion 43 of the end cap 40 begins to be inserted into the insertion hole 58 that opens at the rear end of the glass run upper edge portion 11. When the front end of the molding 30 reaches the front end of the glass run upper edge portion 11 of the glass run main body 20, the locking portion 43 of the end cap 40 is completely inserted into the insertion hole 58 of the glass run upper edge portion 11, and the locking portion 43 is locked to the rear end of the glass run upper edge portion 11.

[0077] By assembling the molding 30 to the glass run body 20 in the above manner, the assembly work of the glass run 1 for an automobile door is completed.

[0078] In the slide assembly process, the method of sliding the molding 30 relative to the glass run body 20 has been described, but the reverse method of sliding the glass run body 20 relative to the molding 30 may also be used.

[0079] (Effects of the embodiment) As described above, according to this embodiment, when attaching the vehicle door glass run 1 to the right rear door 100, the glass run upper edge portion 11 can be attached and fixed to the glass run mounting plate 135 of the window frame 130 from the outside of the vehicle compartment toward the inside of the vehicle compartment. The vehicle door glass run 1 is previously set in a state in which the locking portion 43 of the end cap 40 is inserted into the insertion hole 58 of the glass run upper edge portion 11 and locked to the glass run upper edge portion 11. In this state, the fixing plate 42 of the end cap 40 is fixed to the molding 30, and the fixing plate 42 is directly fitted to the outside of the vehicle of the glass run upper edge portion 11. Therefore, the rear end of the molding 30 is directly positioned and fixed to the glass run upper edge portion 11 via the end cap 40. This makes it difficult for the rear end of the molding 30 to shift upward from its normal position, even if the glass run upper edge portion 11 is pushed up by the window glass 121 when the window glass 121 is fully closed.

[0080] The above-described embodiments are merely examples in all respects and should not be construed as limiting. Furthermore, all modifications and variations within the scope of the claims are within the scope of the present invention. [Industrial Applicability]

[0081] As described above, the present invention can be applied to a glass run disposed on a window frame of an automobile door. [Explanation of symbols]
