Description

Sash structure for vehicle window glass and vehicle

[0001] The present invention relates to a sash structure for a vehicle window glass and a vehicle.

[0002] Patent Document 1 discloses an automobile including a sash of a window frame of a window glass and a window glass provided on a door panel so as to be movable up and down.

[0003] Japanese Patent Laid-Open No. 2007-137144

[0004] In the disclosure of Patent Document 1, it is preferable to make the surface difference between the outer surface of the sash and the outer surface of the window glass as small as possible to streamline the air of the automobile during running and improve the running performance of the automobile. However, when the surface difference between the outer surface of the sash and the outer surface of the window glass is small, when the window glass is lowered in rainy weather, rainwater from the outer surface of the sash may enter the vehicle interior.

[0005] The present invention has been made under the above circumstances, and an object thereof is to provide a sash structure for a vehicle window glass and a vehicle capable of suppressing water from the outer surface of the sash from entering the vehicle interior.

[0006] In order to achieve the above object, a sash structure for a vehicle window glass according to the present invention is disposed in a sash of a window frame of a vehicle, and includes a glass run provided on an outer peripheral portion of a window frame opening, and a window glass having an end portion fitted into the glass run and provided so as to be movable up and down. A lip portion is provided at an upper portion of the window frame. In a state where the window frame opening is opened by the window glass, the lip portion protrudes outward of the vehicle compartment from an outer end portion of the glass run in a top view, and in a state where the window frame opening is closed by the window glass, the lip portion is pushed into the vehicle compartment side by the window glass and stored.

[0007] According to the present invention, in a state where the window frame opening is opened by the window glass, the lip portion protrudes outward of the vehicle compartment from an outer end portion of the glass run in a top view. Therefore, water from the outer surface of the sash drops onto the lip portion before entering the vehicle interior. Thereby, it is possible to suppress water from the outer surface of the sash from entering the vehicle interior.

[0008] This is a side view of a vehicle according to Embodiment 1 of the present invention. This is a top view of a vehicle according to Embodiment 1.

This is a cross-sectional view taken along line XI-XI in Figure 10.

[0009] Embodiment 1. Hereinafter, a sash structure 1 for a vehicle window glass according to an embodiment and a vehicle 100 equipped therewith will be described with reference to the figures. For ease of understanding, mutually orthogonal XYZ coordinates will be set and referred to as appropriate. As shown in Figures 1A and 1B, the X-axis direction of the XYZ coordinates is the vehicle width direction of the vehicle 100, the Y-axis direction is the front-rear direction of the vehicle 100, and the Z-axis direction is the vehicle height direction of the vehicle 100. In each figure, the same reference numerals indicate the same or corresponding parts.

[0010] Vehicle 100 comprises, for example, a body 110, tires 120, a gasoline engine, a sash structure 1 for vehicle windows, and other automobile parts, as shown in Figures 1A and 1B. Vehicle 100 is, for example, an automobile equipped with a gasoline engine for driving the tires 120. However, it is not limited to this. Vehicle 100 may be an electric vehicle equipped with a drive motor, a hybrid vehicle equipped with both a gasoline engine and a drive motor, an automobile equipped with a diesel engine, and the like.

[0011] The sash structure 1 for the vehicle window glass is provided on the left and right side doors of a vehicle 100 equipped with a window E. In this embodiment, the left front door will be described, but the other doors have a similar structure. The sash structure 1 for the vehicle window glass comprises a door body 10 and a sash 20. In addition, as shown in Figures 2 and 3, the sash structure 1 for the vehicle window glass comprises a window glass 30 and a glass run 40 in addition to the door body 10 and sash 20. The aforementioned window E is provided on the side door and comprises a window glass 30 and a sash 20.

[0012] As shown in Figures 1A and 1B, the door body 10 is provided to be openable and closable from the vehicle 100 so that the driver can get in and out of the vehicle 100. In this embodiment 1, the door body 10 is exemplified as a hinged door that swings outwards from the vehicle around a pivot point as shown in the swing direction A1. However, it is not limited to this. The door body 10 may also be a sliding door that opens and closes parallel to the surface of the vehicle body 110. As shown in Figures 2 and 3, the door body 10 is provided with a window glass 30. The window glass 30 is fitted into a glass run 40 and is provided to be able to move up and down as shown in the up and down direction A2. For example, the door body 10 has an outer panel 11 and an inner panel 12, and the lowered window glass 30 is housed between the outer panel 11 and the inner panel 12.

[0013] The sash 20 is a window frame that holds the window glass 30 in the correct position when it is raised to its upper limit, i.e., when the window E is fully closed, and also allows it to move smoothly up and down. Together with the window glass 30, the sash 20 prevents rain and wind from entering the vehicle. The sash 20 has a recessed portion 21 into which the glass run 40 is fitted, and a protruding portion 23 into which the glass run 40 is fitted.

[0014] The window glass 30 is a transparent, plate-shaped member capable of closing the window E of the vehicle 100. The window glass 30 consists of a single glass plate, however, it is not limited to this. The window glass 30 only needs to allow visibility to the outside and prevent rain and wind from entering the vehicle. For example, the window glass 30 may be laminated glass, made by bonding two panes of glass together with a resin in between, in order to improve sound insulation inside the vehicle 100. The window glass 30 is installed in the door body 10. The window glass 30 is installed so that it can move up and down to close or open the window E, and when the window E is opened, the air inside the vehicle 100 is ventilated. The window glass 30 is fully closed when its end moves upward (in the +Z direction) and is positioned on the sash 20, and comes into contact with the glass run 40 provided on the outer periphery of the window frame opening. The window glass 30 is fully open when it moves downward (in the -Z direction) and is stored between the outer panel and the inner panel of the door body 10. When the window glass 30 is fully closed, it has a shape that slopes inward toward the inside of the vehicle as it approaches its upper end. When the window E is opened, the upper end of the window glass 30 moves diagonally downward toward the outside of the vehicle, creating a gap in the vehicle width direction between the upper end of the window glass 30 and the sash 20.

[0015] The glass run 40 is made of an elastic material. The glass run 40 guides the raising and lowering of the window glass 30 and suppresses vibrations of the window glass 30 while driving or when the door is closed. The glass run 40 has a lip portion 50, a window glass holding portion 60, and a base portion 70.

[0016] As shown in Figure 3, the lip portion 50 is formed to protrude from the base portion 70 and has a cylindrical shape with the Y-axis as its axis. The lip portion 50 is also shaped to catch water dripping from the vehicle exterior surface 20b of the sash 20 during rainy weather. The lip portion 50 is made of an elastic material. When the window glass 30 rises and contacts the glass run 40, closing the window E completely, the lip portion 50 is pressed by the window glass 30, causing it to elastically deform and be retracted inside the vehicle beyond the window glass 30. In other words, the lip portion 50 is provided on the upper part of the window frame, and when the window frame opening is opened by the window glass 30, it protrudes further out of the vehicle interior than the outer end of the glass run 40 when viewed from above. Specifically, when the window frame opening is opened by the window glass 30, the lip portion 50 protrudes further out of the vehicle interior than the outer end of the main body of the glass run 40 excluding the lip portion 50. As shown in Figure 4, when the window glass 30 descends from its fully closed position and the window E opens, the lip portion 50 elastically recovers as its elastic deformation is relieved, and the outer end 50a of the lip portion 50 is formed to protrude outwards. At this time, the outer end 50a of the lip portion 50 protrudes outwards beyond the outer end 20a of the sash 20. In other words, when the window frame opening is closed by the window glass 30, the lip portion 50 is pushed inwards and stored by the window glass 30. The protruding length from the outer end 20a of the sash 20 to the end 50a of the lip portion 50 at this time is, for example, in the range of 8 to 10 millimeters. However, it is not limited to this. The protruding length L1 may be, for example, a dimension other than the range of 8 to 10 millimeters.

[0017] Furthermore, the lip portion 50 is formed to incline upward toward the outside of the vehicle when the window glass 30 descends from its fully closed state and the window E opens. By being formed to incline upward, the lip portion 50 is designed to easily catch water dripping from the outer surface of the sash 20. The lip portion 50 also has a multi-wall structure having a first wall portion 51 and a second wall portion 52. The second wall portion 52 of the two wall portions 52 is located closer to the window glass 30 than the first wall portion 51. Specifically, as shown in Figure 3, when the window glass 30 is fully closed, the second wall portion 52 is located closer to the +X side than the first wall portion 51. For example, as shown in Figure 4, when the window glass 30 has descended from its fully closed state, the second wall portion 52 is located lower than the first wall portion 51.

[0018] As shown in Figures 3 and 4, the window glass holding portion 60 is a part that is fitted into the recessed portion 21 of the sash 20. The window glass holding portion 60 holds the window glass 30 in a state where the window frame opening is closed by the window glass 30, i.e., by the raising of the window glass 30, in order to prevent water from entering the vehicle interior. The window glass holding portion 60 is formed in a polygonal cylindrical shape with the Y-axis direction as the cylindrical axis. The window glass holding portion 60 has an upper wall portion 61 positioned on the bottom surface 21a of the recessed portion 21, and a lower wall portion 62 provided below the upper wall portion 61 (on the -Z side). The lower wall portion 62 is formed opposite to the upper wall portion 61 and is formed to bend when it comes into contact with the upper end of the raised window glass 30.

[0019] The upper wall portion 61 is the part positioned on the bottom surface 21a of the sash 20. The upper wall portion 61 is made of hard rubber. However, it is not limited to this. The upper wall portion 61 may be made of a material other than hard rubber. The upper wall portion 61 should be made of a material that is difficult to deform so that the window glass holding portion 60 does not come off the recessed portion 21. However, it is preferable that the upper wall portion 61 be made of an elastic material so as not to damage the sash 20.

[0020] The lower wall portion 62 is the part that contacts the upper end of the window glass 30. The lower wall portion 62 is made of a softer, more elastic material than the upper wall portion 61. When the lower wall portion 62 contacts the upper end of the window glass 30, it flexes and adheres tightly to the inner surface of the window glass 30 facing the vehicle 100 and the outer surface of the window glass 30. The lower wall portion 62 maintains airtightness by adhering tightly to the two surfaces of the window glass 30.

[0021] The base portion 70 is fixed to the sash 20. The base portion 70 has a cylindrical shaft portion 71 formed in a rectangular tube shape with the Y-axis direction as the axis, and a clamping portion 72 that protrudes from the cylindrical shaft portion 71. The clamping portion 72 is shaped to be able to be clamped into a plate-shaped projection portion 23 formed on the sash 20. The window glass holding portion 60 and the lip portion 50 are integrally provided on the base portion 70 and support the window glass holding portion 60 and the lip portion 50. The window glass holding portion 60 is also provided on the clamping portion 72 via a connecting portion 73. The lip portion 50 is formed to protrude outwards from the lower end of the cylindrical shaft portion 71.

[0022] The cylindrical shaft portion 71 is a rectangular tube shape with a hollow section extending in the Y-axis direction. At least a portion of the cylindrical shaft portion 71 is made of an elastic material. The deformation of the hollow section of the cylindrical shaft portion 71 facilitates the deformation of the lip portion 50.

[0023] The clamping portion 72 is the part that fixes the base portion 70 to the sash 20. The clamping portion 72 fixes the base portion 70 to the sash 20 by clamping the protruding portion 23 of the sash 20. The clamping portion 72 is made of hard rubber. However, it is not limited to this. The clamping portion 72 should be made of a material that is resistant to deformation so that the base portion 70 does not come off the protruding portion 23. However, it is preferable that the clamping portion 72 be made of an elastic material so as not to damage the protruding portion 23.

[0024] A drainage channel 80 is formed between the base portion 70 and the lip portion 50, through which water flowing in from the lip portion 50 passes. The drainage channel 80 is designed such that, for example, water flows to the front or rear side of the vehicle 100 before flowing down below the vehicle 100.

[0025] As described above, in this embodiment 1, as shown in Figures 3 and 4, when the window glass 30 descends from a fully closed state and the window E of the vehicle 100 opens, the outer end 50a of the lip portion 50 protrudes outward beyond the outer end 20a of the sash 20. That is, when the window frame opening is opened by the window glass 30, i.e., by the descent of the window glass 30, the lip portion 50 protrudes outward from the outer end of the glass run 40 when viewed from above. Therefore, rainwater from the outer surface of the sash 20 falls onto the lip portion 50 before entering the vehicle 100. The rainwater W that falls onto the lip portion 50 then flows into the drainage channel 80. The rainwater W flows to the front or rear of the vehicle via the drainage channel 80, and flows down below the vehicle 100 without entering the vehicle 100. This prevents water from the outer surface of the sash 20 from entering the vehicle 100. Furthermore, even when a flush surface is created to minimize the surface difference between the outer surface 30a of the window glass 30 and the outer surface of the sash 20, it is possible to suppress water from dripping from the outer surface of the sash 20 into the vehicle 100.

[0026] Furthermore, in this embodiment 1, the lip portion 50 is formed to be inclined upward toward the outside of the vehicle 100, as shown in Figure 4. By being formed to be inclined upward, the lip portion 50 is designed to facilitate the flow of water that drips from the outer surface of the sash 20 into the drainage channel 80. This enhances the effect of suppressing water from the outer surface of the sash 20 from entering the vehicle 100.

[0027] Furthermore, in this embodiment 1, the lip portion 50 has a multi-wall structure having a first wall portion 51 and a second wall portion 52, as shown in Figure 3. Therefore, the lip portion 50 is formed to allow water dripping from the outer surface of the sash 20 to flow easily into the drainage channel 80 while ensuring its flexibility. This enhances the effect of suppressing water from entering the vehicle 100 from the outer surface of the sash 20 while ensuring the flexibility of the lip portion 50.

[0028] Furthermore, in this embodiment 1, the lip portion 50 is formed to protrude from the base portion 70. This makes it easier to form a drainage channel 80 between the base portion 70 and the lip portion 50. As a result, it is possible to suppress water from the outer surface of the sash 20 from entering the vehicle 100.

[0029] Embodiment 2. Hereinafter, a vehicle window glass according to Embodiment 2 and a vehicle 100 equipped therewith will be described with reference to the figures. For ease of understanding, mutually orthogonal XYZ coordinates will be set and referred to as appropriate. As shown in Figures 1A, 1B and 5, the X-axis direction of the XYZ coordinates is the vehicle width direction of the vehicle 100, the Y-axis direction is the front-rear direction of the vehicle 100, and the Z-axis direction is the vehicle height direction of the vehicle 100. In each figure, the same reference numerals indicate the same or corresponding parts.

[0030] Vehicle 100 includes, for example, a body 110, tires 120, a gasoline engine, vehicle doors D, and other automobile parts, as shown in Figures 1A and 1B. Vehicle 100 is, for example, an automobile equipped with a gasoline engine for driving the tires 120. However, it is not limited to this. Vehicle 100 may be an electric vehicle equipped with a drive motor, a hybrid vehicle equipped with both a gasoline engine and a drive motor, an automobile equipped with a diesel engine, and the like.

[0031] Vehicle doors D are provided on the left and right side doors of the vehicle 100. In this embodiment, the left front door will be described, but the other doors have a similar structure. As shown in Figure 5, the vehicle door D comprises a door body 10 and a window glass 30. In addition, as shown in Figures 6 and 7, the vehicle door D comprises a door frame member 25, a window frame rubber member 40-1, and a door regulator 90 for raising and lowering the window glass 30, in addition to the door body 10 and window glass 30. The vehicle door D in Figure 7 represents the front right door.

[0032] The door body 10 is provided to be openable and closable from the vehicle 100 so that the driver can get in and out of the vehicle 100. In this second embodiment, the door body 10 is exemplified as a hinged door that swings outwards from the vehicle around a pivot point as shown in the swing direction A1. However, it is not limited to this. The door body 10 may also be a sliding door that opens and closes parallel to the surface of the vehicle body 110. The door body 10 is provided with a window glass 30. The window glass 30 is provided to be able to move up and down relative to the window frame rubber member 40-1 as shown in the up and down direction A2. For example, the door body 10 has an outer panel 11 and an inner panel 12, and the lowered window glass 30 is housed between the outer panel 11 and the inner panel 12.

[0033] Since the door frame member 25 is fixed to the door body 10, when the door body 10 is opened or closed, it opens and closes together with the door body 10, along with the window glass 30 and the like. A window frame rubber member 40-1 is attached to the door frame member 25. Furthermore, the door frame member 25 is made of a material with higher rigidity than the window frame rubber member 40-1 in order to increase the strength of the vehicle door D. In this second embodiment, the vehicle door D is not a frameless door without a door frame member 25, but a framed door with a door frame member 25. The vehicle door D is opened and closed from the vehicle 100 when the driver gets in or out of the vehicle 100.

[0034] The window glass 30 is a transparent plate-shaped member capable of closing the window E of the vehicle 100. The window glass 30 is provided so as to be able to move up and down to close or open the window E, for example, when the window E is opened, the air inside the vehicle 100 is ventilated. The window glass 30 is in a fully closed state when its end moves upward (+Z direction) and contacts the window frame rubber member 40-1 attached to the door frame member 25. The window glass 30 is in a fully open state when it moves downward (-Z direction) and is stored between the outer panel 11 and the inner panel 12 of the door body 10. In the fully closed state, the window glass 30 has a shape that slopes inward towards the vehicle as it approaches its upper end. The upper end of the window glass 30 moves outward as the window glass 30 moves downward (-Z direction), and a gap is created between the upper end of the window glass 30 and the window frame in the vehicle width direction (X-axis direction). In this embodiment 2, the window glass 30 is a laminated glass comprising a first glass 31 and a second glass 32. More specifically, in this second embodiment, the window glass 30 comprises a first glass 31, a second glass 32, and a resin part 33 (resin layer).

[0035] The first glass 31 is formed from a plate-like member having a uniform thickness t1. The thickness t1 of the first glass 31 is, for example, 2 mm to 3.5 mm. The roof portion 31a, which is the upper (+Z side) end of the first glass 31, is the portion that contacts the window frame rubber member 40-1 located on the door frame member 25 when the door is fully closed, as shown in Figure 6. The roof portion 31a of the first glass 31, which is its upper (+Z side) end, is formed to protrude more than the roof portion 32a of the second glass 32. As a result, a step 34 is formed between the roof portion 31a of the first glass 31 and the roof portion 32a of the second glass 32.

[0036] Furthermore, as shown in Figures 7 and 8, the rear end (+Y side) 31b of the first glass 31 is formed to protrude further than the rear end (+Y side) 32b of the second glass 32. As a result, a step 34 is also formed between the rear end (+Y side) 31b of the first glass 31 and the rear end (+Y side) 32b of the second glass 32. In addition to Figure 7, the vehicle door in Figure 8 also represents the front right door. Furthermore, in this embodiment 2, the front end (-Y side) 31c of the first glass 31 is formed to protrude further than the front end (-Y side) 32c of the second glass 32, and a step 34 is also formed between the front end (-Y side) 31c of the first glass 31 and the front end (-Y side) 32c of the second glass 32. Furthermore, the lower (-Z side) end 31d of the first glass 31 is not formed to protrude more than the lower (-Z side) end 32d of the second glass 32. Since the lower end 31d of the first glass 31 and the lower end 32d of the second glass 32 are housed in the door body 10, there is no need to create a flush surface, and therefore no step 34 is formed there.

[0037] The second glass 32 is formed from a plate-like member having a uniform thickness t2. The thickness t2 of the second glass 32 may be the same as or different from that of the first glass 31, for example. The upper end surface of the roof portion 32a, which is the upper (+Z side) end of the second glass 32, is positioned close to or in contact with the window frame rubber member 40-1 when fully closed, as shown in Figure 6, unlike the roof portion 31a of the first glass 31. The second glass 32 is bonded to the first glass 31 and is positioned on the outside of the vehicle.

[0038] Furthermore, the rear (+Y side) end 32b and the front (-Y side) end 32c of the second glass 32 are positioned without contact with the window frame rubber member 40-1, as shown in Figure 8. In this second embodiment, the rear (+Y side) end 32b and the front (-Y side) end 32c of the second glass 32 are positioned without contact with the window frame rubber member 40-1 from the fully closed state to the fully open state.

[0039] The resin portion 33 is a resin layer made of an adhesive used to bond the second glass 32 to the first glass 31. The resin portion 33 is formed from a permeable material. For example, the resin portion 33 is made of PVC (polyvinyl chloride). The thickness of this resin portion 33 is formed to be, for example, 0.5 mm to 1.0 mm.

[0040] The window frame rubber member 40-1 is made of an elastic material. The window frame rubber member 40-1 guides the raising and lowering of the window glass 30 and suppresses vibrations of the window glass 30 while driving or when the door is closed. The window frame rubber member 40-1 has a lip portion 50, a window glass holding portion 60, and a base portion 70.

[0041] As shown in Figure 6, the lip portion 50 is made of an elastic material. When the window glass 30 rises and contacts the window frame rubber member 40-1, thereby fully closing the window E, the lip portion 50 is pressed by the window glass 30, causing it to elastically deform and be retracted inside the vehicle relative to the window glass 30. When the window glass 30 descends from the fully closed position and the window E opens, the elastic deformation of the lip portion 50 is released, causing it to elastically recover, and the outer end portion 50a of the lip portion 50 is formed to protrude outwards from the vehicle.

[0042] The window glass holder 60 is fixed to the door frame member 25. The window glass holder 60 holds the window glass 30 in a way that prevents water from entering the vehicle interior when the window frame opening is closed by the window glass 30. The window glass holder 60 has an end holder 63 that extends in the Y-axis direction and into which the upper end of the window glass 30 fits, and a clamping portion 64 provided on the end holder 63. The clamping portion 64 is shaped to be able to be clamped into a plate-shaped projection 22A formed on the door frame member 25. The lower wall portion 65 provided on the lower side (-Z side) of the window glass holder 60 is shaped to bend when it comes into contact with the upper end of the raised window glass 30.

[0043] The base portion 70 is attached and fixed to a plate-like protruding portion 22B formed on the door frame member 25. A window glass holding portion 60 and a lip portion 50 are provided on this base portion 70. The window glass holding portion 60 is provided at a position shifted upward via a connecting portion 73. The lip portion 50 is formed to protrude in the vehicle exterior direction from the base portion 70.

[0044] A drainage channel 80 through which water flowing in from the lip portion 50 passes is formed between the base portion 70 and the lip portion 50. The drainage channel 80 is formed, for example, such that water flows to the front side or the rear side of the vehicle 100 and then falls downward of the vehicle 100.

[0045] As described above, in the second embodiment, as shown in FIG. 6, the second glass 32 is bonded to the first glass 31. And a roof portion 31a which is an end portion of the first glass 31 is formed to protrude more than a roof portion 32a which is an end portion of the second glass 32. Thereby, a step 34 is formed between the roof portion 31a of the first glass 31 and the roof portion 32a of the second glass 32. That is, the roof portion 31a of the first glass 31 is made to protrude more than the roof portion 32a of the second glass 32 so as to form a step 34 between the roof portion 31a of the first glass 31 and the roof portion 32a of the second glass 32. For this reason, while forming a step 34 at the end portion of the window glass 30, the manufacturing cost can be suppressed. Also, the window glass 30 of the second embodiment can be applied to a frame door type automobile having a door frame member 25 without changing the existing structure.

[0046] Further, the second embodiment includes a resin portion 33 (resin layer) provided between the first glass 31 and the second glass 32 and formed of a resin for bonding the first glass 31 and the second glass 32. For this reason, in the second embodiment, the manufacturing cost can be suppressed as compared with the case of forming a step 34 at the end portion of the window glass 30 by injection molding or the like.

[0047] Furthermore, in this second embodiment, the roof portion 31a of the first glass 31 is formed to protrude above the vehicle 100 more than the roof portion 32a of the second glass 32. Therefore, by adjusting the thickness of the second glass 32 and the amount of protrusion of the first glass 31 (i.e., the size of the second glass 32), the protrusions and irregularities from the outer surface of the vehicle 100 can be reduced. Thus, a flush surface can be achieved by minimizing the surface difference between the outer surface 30a of the window glass 30 and the outer surface 40a of the rubber member 40-1 for the window frame and the outer surface 100a of the metal part of the vehicle body 110. By achieving a flush surface, the air resistance of the vehicle 100 can be reduced, wind noise and vibration during driving can be reduced, and the design of the vehicle body 110 can be improved. As a result, in addition to reducing manufacturing costs, it becomes possible to achieve a flush surface. Furthermore, by adjusting the thickness of the second glass 32 and the amount of protrusion of the first glass 31 (i.e., the size of the second glass 32), a flush surface can be achieved. For this reason, the window glass 30 of this second embodiment can be applied to frame door type automobiles having a door frame member 25 without changing the existing structure.

[0048] Also, in the second embodiment, the roof portion 31a of the first glass 31 is a portion that contacts the window frame rubber member 40-1 in the fully closed state. And the roof portion 32a of the second glass 32 is arranged so as not to contact the window frame rubber member 40-1 in the fully closed state. Therefore, by adjusting the thickness of the second glass 32, protrusions and unevenness can be reduced from the outer surface of the vehicle 100. Thus, it is possible to achieve a flush surface state that minimizes the surface difference between the outer surface 30a of the window glass 30, the outer surface 40a on the vehicle outside of the window frame rubber member 40-1, and the outer surface 100a of the metal portion of the vehicle body 110. By achieving the flush surface state, the air resistance of the vehicle 100 can be reduced, the wind noise and vibration during driving can be reduced, and the design of the vehicle body 110 can be improved. As a result, in addition to suppressing the manufacturing cost, it becomes possible to achieve the flush surface state. Also, by adjusting the thickness of the second glass 32, the flush surface state can be achieved. Therefore, the window glass 30 of the second embodiment can be applied to a frame door type automobile having a door frame member 25 without changing the existing structure.

[0049] Also, in the second embodiment, as shown in FIG. 7, the end portions 31b, 31c of the first glass 31 are formed to protrude forward and backward in the front-rear direction from the end portions 32b, 32c of the second glass 32. Therefore, in the second embodiment, compared with the case where a step 34 is formed at the end of the window glass 30 by injection molding or the like, the manufacturing cost can be suppressed. Also, in addition to suppressing the manufacturing cost, the air resistance of the vehicle 100 can be reduced, the wind noise and vibration during driving can be reduced, and the design of the automobile can be improved.

[0050] Embodiment 3. In Embodiment 2 described above, as shown in Figure 6, the vehicle door D of the automobile is a framed door having a door frame member 25. However, it is not limited to this. The vehicle door D2 may be a frameless door or a sashless door that does not have a door frame member 25. Hereinafter, Embodiment 3, in which a window glass 30 with a step 34 is applied to a frameless door or sashless door of an automobile, will be described with reference to Figures 9 to 11. For the sake of ease of understanding, XYZ coordinates will be set and referred to as appropriate. Except for the differences described, it will be the same as or equivalent to Embodiment 2.

[0051] As shown in Figure 9, the vehicle door D2 comprises a door body 10, a retaining member 20-2, a window glass 30, window frame rubber members 40-1 and 40-2, and a door regulator 90 for raising and lowering the window glass 30. Since the vehicle door D2 is a frameless or sashless door, when the driver gets in or out of the vehicle 100, the upper end, front end, and rear end of the window glass 30 are exposed when the door is opened and closed from the vehicle 100.

[0052] The door body 10 is provided with a window pane 30 that can move up and down relative to the window frame rubber member 40-1 in the direction of vertical movement A2. For example, the door body 10 has an outer panel 11 and an inner panel 12, and the lowered window pane 30 is housed between the outer panel 11 and the inner panel 12.

[0053] The retaining member 20-2 is a window frame that holds the fully closed window glass 30 in the correct position and allows it to be raised and lowered smoothly. Together with the window glass 30, the retaining member 20-2 prevents rain and wind from entering the vehicle. The retaining member 20-2 has a recessed portion 21 into which the window frame rubber member 40-1 is fitted.

[0054] The window glass 30 is a transparent, plate-shaped member capable of closing the window E of the vehicle 100. The window glass 30 is provided so as to be able to move up and down to close or open the window E, for example, when the window E is opened, the air inside the vehicle 100 is ventilated. The window glass 30 is in a fully closed state when its end moves upward (+Z direction) and contacts the window frame rubber member 40-1 provided on the holding member 20-2. The window glass 30 is in a fully open state when it moves downward (-Z direction) and is stored between the outer panel 11 and the inner panel 12 of the door body 10. In the fully closed state, the window glass 30 has a shape that slopes inward towards the vehicle as it approaches its upper end. The upper end of the window glass 30 moves outward as the window glass 30 moves downward (-Z direction), creating a gap between the upper end of the window glass 30 and the window frame in the vehicle width direction (X-axis direction). In this third embodiment, the window glass 30 is a laminated glass comprising a first glass 31 and a second glass 32, and has the same structure as that of the second embodiment. More specifically, in this third embodiment, the window glass 30 comprises a first glass 31, a second glass 32, and a resin part 33 (resin layer).

[0055] The first glass 31 is formed from a plate-like member having a uniform thickness t1. The thickness t1 of the first glass 31 is, for example, 2 mm to 3.5 mm. The roof portion 31a, which is the upper (+Z side) end of the first glass 31, is the portion that contacts the window frame rubber member 40-1 located on the holding member 20-2 when the window is fully closed. The roof portion 31a of the first glass 31 is formed to protrude more than the roof portion 32a of the upper (+Z side) end of the second glass 32. As a result, a step 34 is formed between the roof portion 31a of the first glass 31 and the roof portion 32a of the second glass 32.

[0056] Furthermore, as shown in Figures 10 and 11, the rear end (+Y side) 31b of the first glass 31 does not protrude beyond the rear end (+Y side) 32b of the second glass 32. The vehicle door in Figures 10 and 11 represents the front right door. There is no step 34 between the rear end (+Y side) 31b of the first glass 31 and the rear end (+Y side) 32b of the second glass 32. Also, in this embodiment 3, the front end (-Y side) 31c of the first glass 31 does not protrude beyond the front end (-Y side) 32c of the second glass 32. There is no step 34 between the front end (-Y side) 31c of the first glass 31 and the front end (-Y side) 32c of the second glass 32. Furthermore, the lower (-Z side) end 31d of the first glass 31 is not formed to protrude more than the lower (-Z side) end 32d of the second glass 32. Since the lower end 31d of the first glass 31 and the lower end 32d of the second glass 32 are housed in the door body 10, there is no need to create a flush surface, and therefore no step 34 is formed there.

[0057] The second glass 32 is formed from a plate-like member having a uniform thickness t2. The thickness t2 of the second glass 32 may be the same as or different from that of the first glass 31, for example. The upper end surface of the roof portion 32a, which is the upper (+Z side) end of the second glass 32, is positioned close to or in contact with the window frame rubber member 40-1 when fully closed, as shown in Figure 9, unlike the roof portion 31a of the first glass 31. The second glass 32 is bonded to the first glass 31 and is positioned on the outside of the vehicle.

[0058] The resin portion 33 is an adhesive that bonds the second glass 32 to the first glass 31. The resin portion 33 is made of a permeable material. For example, the resin portion 33 is made of PVC (polyvinyl chloride). The thickness of this resin portion 33 is formed to be, for example, 0.5 mm to 1.0 mm.

[0059] The window frame rubber member 40-1 is made of an elastic material. The window frame rubber member 40-1 guides the raising and lowering of the window glass 30 and suppresses vibrations of the window glass 30 while driving or when the door is closed. The window frame rubber member 40-1 is formed in a cylindrical shape with the Y-axis direction as the axis of the cylinder. The window frame rubber member 40-1 has an upper wall portion 41 that contacts the bottom surface 21a of the recessed portion 21, and a lower wall portion 42 that is provided below the upper wall portion 41 (on the -Z side). The lower wall portion 42 is formed opposite to the upper wall portion 41 and is formed to bend when it comes into contact with the upper end of the raised window glass 30.

[0060] The window frame rubber member 40-2 is fixed to the end of the metal part of the vehicle 100. The window frame rubber member 40-2 has a clamping portion 43. The clamping portion 43 is shaped to be able to be clamped onto the plate-shaped protrusion 102 of the metal part of the vehicle 100. The window frame rubber member 40-2 is also provided with a lip portion 50.

[0061] The lip portion 50 is made of an elastic material. When the window glass 30 rises and contacts the window frame rubber member 40-1, thereby fully closing the window E, the lip portion 50 is pressed by the window glass 30, causing it to elastically deform and be retracted inside the vehicle relative to the window glass 30. When the window glass 30 descends from the fully closed position and the window E opens, the elastic deformation of the lip portion 50 is released, causing it to elastically recover, and the outer end portion 50a of the lip portion 50 protrudes outward from the vehicle.

[0062] The window frame rubber member 40-2 has a drainage channel 80 formed at the base end of the lip portion 50 through which water flowing in from the lip portion 50 passes. The drainage channel 80 is formed so that, for example, water flows to the front or rear side of the vehicle 100 before flowing down below the vehicle 100.

[0063] As described above, in this embodiment 3, as shown in Figure 9, the second glass 32 is bonded to the first glass 31. The roof portion 31a, which is the end of the first glass 31, is formed to protrude more than the roof portion 32a, which is the end of the second glass 32. As a result, a step 34 is formed between the roof portion 31a of the first glass 31 and the roof portion 32a of the second glass 32. Therefore, it is possible to suppress manufacturing costs while forming a step 34 at the end of the window glass 30. Furthermore, the window glass 30 of this embodiment 3 can be applied to frameless door type or sashless type automobiles that do not have a door frame member without changing the existing structure.

[0064] Furthermore, this third embodiment includes a resin portion 33 provided between the first glass 31 and the second glass 32, which is formed from resin for bonding the first glass 31 and the second glass 32 together. Therefore, in this third embodiment, manufacturing costs can be reduced compared to the case where a step 34 is formed at the edge of the window glass 30 by injection molding or the like.

[0065] Furthermore, in this third embodiment, the roof portion 31a of the first glass 31 is formed to protrude above the vehicle 100 more than the roof portion 32a of the second glass 32. Therefore, by adjusting the thickness of the second glass 32 and the amount of protrusion of the first glass 31 (i.e., the size of the second glass 32), the protrusions and irregularities from the outer surface of the vehicle 100 can be reduced. Thus, a flush surface can be achieved by minimizing the surface difference between the outer surface 30a of the window glass 30 and the outer surface 40a of the rubber member 40-1 for the window frame and the outer surface 100a of the metal part of the vehicle body 110. By achieving a flush surface, the air resistance of the vehicle 100 can be reduced, which can reduce wind noise and vibration during driving and improve the design of the automobile. As a result, in addition to suppressing manufacturing costs, it becomes possible to achieve a flush surface. Furthermore, by adjusting the thickness of the second glass 32 and the amount of protrusion of the first glass 31 (i.e., the size of the second glass 32), a flush surface can be achieved. For this reason, the window glass 30 can be applied to frameless door types or sashless types that do not have a door frame member without changing the existing structure.

[0066] Furthermore, in this third embodiment, the roof portion 31a of the first glass 31 is in contact with the window frame rubber member 40-1 when fully closed. The roof portion 32a of the second glass 32 is positioned without contact with the window frame rubber member 40-1 when fully closed. Therefore, by adjusting the thickness of the second glass 32, the protrusions and unevenness from the outer surface of the vehicle 100 can be reduced. Thus, a flush surface can be achieved by minimizing the surface difference between the outer surface 30a of the window glass 30 and the outer surface 40a of the window frame rubber member 40-1 and the outer surface 100a of the metal part of the vehicle body 110. By achieving a flush surface, the air resistance of the vehicle 100 can be reduced, wind noise and vibration during driving can be reduced, and the design of the vehicle body 110 can be improved. As a result, in addition to suppressing manufacturing costs, it becomes possible to achieve a flush surface. Furthermore, a flush surface can be achieved by adjusting the thickness of the second glass 32. Therefore, the window glass 30 can be applied to a frame door type automobile having a door frame member 25 without changing the existing structure. Furthermore, the same effects as in the second embodiment can be achieved in the third embodiment.

[0067] Although the embodiments described above have been explained, the present invention is not limited to the embodiments described above.

[0068] For example, in this embodiment, as shown in Figure 4, the lip portion 50 is formed to incline upward toward the outside of the vehicle 100 when the window E is opened. However, the shape of the lip portion 50 is not limited to this. The lip portion 50 may be formed in a shape other than that of this embodiment, for example, by protruding horizontally.

[0069] Furthermore, in this embodiment, the lip portion 50 has a multi-wall structure having a first wall portion 51 and a second wall portion 52, as shown in Figure 4. However, it is not limited to this. The lip portion 50 may, for example, have a structure having only one wall portion instead of a multi-wall structure.

[0070] Furthermore, as shown in Figures 6 and 9, this embodiment includes a resin portion 33 provided between the first glass 31 and the second glass 32, formed from a resin for bonding the first glass 31 and the second glass 32 together. However, it is not limited to this. This embodiment does not need to have a resin portion 33. For example, in this embodiment, the first glass 31 and the second glass 32 may be bonded together using a material other than resin, as long as it can be bonded together. Also, although the resin portion 33 in this embodiment is formed from PVC (polyvinyl chloride), it is not limited to this, and may be formed from a material other than PVC.

[0071] Furthermore, in this embodiment, the lower (-Y side) end 31d of the first glass 31 is not formed to protrude more than the lower (-Y side) end 32d of the second glass 32. However, it is not limited to this. The lower (-Y side) end 31d of the first glass 31 may be formed to protrude more than the lower (-Y side) end 32d of the second glass 32. However, since the lower (-Y side) end 31d of the first glass 31 and the lower (-Y side) end 32d of the second glass 32 are housed in the door body 10, from the viewpoint of manufacturing cost, the end 31d does not need to protrude more than the end 32d.

[0072] Furthermore, in these two and three embodiments, when the window E of the vehicle 100 is opened, the outer end 50a of the lip portion 50 may or may not protrude outward from the outer end of the window frame rubber member 40-1 or the retaining member 20-2.

[0073] The present invention allows for various embodiments and modifications without departing from the broad spirit and scope of the invention. Furthermore, the embodiments described above are for illustrative purposes only and do not limit the scope of the invention. In other words, the scope of the invention is indicated by the claims, not by the embodiments. Various modifications made within the scope of the claims and the equivalent significance of disclosure are considered to be within the scope of the invention.
