Description

  The present invention relates to a vehicle window glass structure, and more particularly, to a vehicle window glass structure in which a frame portion is provided on an outer edge of a vehicle window glass and a lip portion that is in close contact with the vehicle is provided on the frame portion.

There is a vehicle window glass structure in which a lip portion made of resin is provided on the peripheral edge portion of a window glass for a vehicle, the lip portion is closely attached to the peripheral edge of the window opening, and the peripheral edge of the window opening is sealed.
In the vehicle window glass structure, a resin-made frame portion is provided on the periphery of the vehicle window glass, and the lip portion is integrally formed with the frame portion, so that the lip portion protrudes from the outer periphery of the frame portion.
As the material for the frame portion and the lip portion, soft polyvinyl chloride or the like is usually employed.

By attaching the vehicle window glass structure to the window frame of the vehicle body, the lip portion is brought into close contact with the vehicle, and the gap between the vehicle and the window glass is sealed.
By sealing the gap between the vehicle and the window glass with the lip portion, water and dust outside the vehicle are prevented from entering the vehicle interior through the gap between the vehicle and the window glass.

By the way, when the automobile travels, the lip portion and the vehicle vibrate differently, and thus the lip portion and the vehicle may rub against each other to generate abnormal noise.
In order to prevent the generation of noise due to this rubbing, a vehicle window glass structure in which a lip portion is formed of a member separate from a frame portion is known (for example, see Patent Document 1).
Japanese Patent Laid-Open No. 2002-129839 (Japanese Patent Laid-Open No. 14-129839) (FIG. 4)

Patent document 1 is demonstrated based on the following drawings.
FIG. 11 is a diagram for explaining a conventional basic configuration.
The vehicle window glass structure 200 is provided with a resin frame portion 203 on the periphery 202 of the vehicle window glass 201, and a lip portion 204 is formed on the frame portion 203 by, for example, two-color molding, so that the frame portion 203 can be formed from the outer periphery. The lip portion 204 is projected.
Thus, by forming the frame portion 203 and the lip portion 204 in two colors, the material of the lip portion 204 can be made different from that of the frame portion 203.

Therefore, it is possible to select a material having a so-called low friction coefficient as the material of the lip portion 204. Thereby, the abnormal noise which generate | occur | produces when the lip | rip part 204 and the vehicle 205 rub against each other can be suppressed.
Here, the material having a low friction rate refers to a material that can smoothly rub against other members in order to suppress the generation of abnormal noise due to friction.

However, in order to form the frame portion 203 and the lip portion 204 in two colors, the lip portion 204 must be welded to the frame portion 203.
Therefore, it is necessary to select a material having two kinds of characteristics as a material of the lip portion 204, such as a material having a low friction coefficient and high weldability to the frame portion 203.

For this reason, when the material of the lip part 204 is selected, the range of material selection is narrowed, which causes a long time for selecting the material of the lip part 204.
Furthermore, by selecting a material with a low friction coefficient and high weldability as the material of the lip portion 204, an expensive material is selected as the lip portion 204, which hinders cost reduction. .

  In addition, if the frame portion 203 and the lip portion 204 are integrally formed by two-color molding, if the lip portion 204 is damaged, it is necessary to replace the vehicle window glass structure 200 as a whole. It becomes a hindrance to hold down expenses.

  The present invention suppresses abnormal noise that occurs when the lip part rubs against the vehicle, makes it possible to easily select the material of the lip part, and to select an inexpensive material for the lip part. It aims at providing the window glass structure for vehicles which can exchange only a part.

  The invention according to claim 1 is a vehicle window glass structure in which a frame portion is provided at an outer edge of the vehicle window glass, and a lip portion that is in close contact with the vehicle is provided on the frame portion. The lip portion is defined as the frame portion. As a separate member, the lip portion is integrated with the frame portion by fitting and coupling.

The lip portion is a separate member from the frame portion, and the lip portion is fitted and joined to the frame portion. Therefore, it is not necessary to select a material having high weldability with respect to the frame portion as the lip portion, and it is possible to select only a material having a low friction coefficient.
By selecting a material having a low coefficient of friction as the lip portion, it is possible to suppress abnormal noise generated when the lip portion and the vehicle rub against each other.
Moreover, since it is only necessary to provide a material with a low friction coefficient as the lip portion, the material of the lip portion can be easily selected, and the degree of freedom in design can be increased.

Furthermore, since it is only necessary to provide a material with a low friction coefficient as the lip portion, an inexpensive material can be selected.
In addition, since the lip portion is a separate member from the frame portion and the lip portion is fitted and coupled to the frame portion, only the lip portion can be replaced.

  The invention according to claim 2 is characterized in that a fitting concave portion is formed in the frame portion, a fitting convex portion is formed in the lip portion, and the fitting convex portion is fitted in the fitting concave portion.

By fitting the fitting convex part of the lip part into the fitting concave part of the frame part, the lip part can be coupled to the frame part relatively easily and reliably.
By the way, in order to form the recessed part for fitting, a pair of wall part is required on both sides. For this reason, in order to form the recessed part for fitting, it is necessary to ensure a comparatively big site | part. On the other hand, the fitting convex portion only needs to form a protrusion, and therefore can be formed in a relatively small portion compared to the fitting concave portion.
Therefore, a concave portion for fitting was formed in a frame portion having a width larger than that of the lip portion, and a convex portion for fitting was formed in the lip portion. Thereby, the recessed part for fitting and the convex part for fitting can be formed in a suitable shape.

  The invention according to claim 3 is characterized in that the lip portion is made of a different material for each part by two-color molding or the like.

By configuring the lip portion with a different material for each portion, it is possible to form the fitting convex portion of the lip portion with a hard material and the other portion with a material having a low friction coefficient.
By forming the fitting convex portion with a hard material in this manner, the fitting convex portion can be firmly fitted into the fitting concave portion, and the lip portion can be fitted and coupled to the frame portion even better.

  The invention according to claim 4 is characterized in that a hollow portion is formed in the fitting convex portion to improve the deformability of the fitting convex portion.

  By forming the hollow portion in the fitting convex portion, it becomes possible to improve the deformability of the fitting convex portion, and the fitting convex portion can be easily and reliably fitted into the fitting concave portion.

In the invention which concerns on Claim 1, there exists an advantage that the window glass structure for vehicles excellent in living property can be obtained by selecting the material of a low friction coefficient for a lip | rip material, and suppressing generation | occurrence | production of abnormal noise.
In addition, there is an advantage that the design time of the vehicle window glass structure can be shortened by widening the selection of the material of the lip portion and increasing the freedom of design.

Further, by selecting an inexpensive material as the lip material, there is an advantage that the cost of the vehicle window glass structure can be suppressed.
In addition, by allowing only the lip portion to be replaced, there is an advantage that the cost for repair can be suppressed.

In the invention which concerns on Claim 2, there exists an advantage that a lip | rip part can be couple | bonded easily and reliably with a frame part by fitting the convex part for fitting to the recessed part for fitting.
Furthermore, there exists an advantage that a lip | rip part can be more reliably couple | bonded with a frame part by making the recessed part for fitting and the convex part for fitting into a suitable shape.

  In the invention which concerns on Claim 3, there exists an advantage that a lip | rip part can be combined still more favorably by forming the convex part for fitting with a hard material.

  In the invention which concerns on Claim 4, there exists an advantage that the convex part for fitting can be easily and reliably engage | inserted in the concave part for fitting by improving the deformability of the convex part for fitting.

As a resin material for the frame portion 31, soft vinyl chloride is used as an example, but is not limited thereto.

  The fitting recess 35 is formed with protrusions 37, 37 on a pair of wall surfaces, thereby forming a lock space 38 at the bottom of the fitting recess 35, and tapered surfaces 39, 39 ( 4 (a) is also formed. The width W2 of the lock space 38 is formed to be larger than the gap S between the pair of projecting pieces 37, 37.

The lip portion 32 is formed with a fitting convex portion 42 from the base portion 41 toward the quarter window glass 21, and a lip main body 43 (see also FIG. 4B) is formed on the opposite side of the quarter window glass 21 from the base portion 41. Is.
The base 41 is a member formed in a substantially rectangular cross section. A corner 41 a on the vehicle side of the base 41 (see also FIG. 4B) is formed so as to be fitted into the step 34 of the frame 31.

The fitting convex portion 42 is formed with tapered surfaces 44, 44 on the quarter window glass 21 side of the base portion 41, and a neck portion 46 is formed on the quarter window glass 21 side of the tapered surfaces 44, 44. An extended portion 47 (see also FIG. 4B) is formed on the quarter window glass 21 side.

It is formed so as to be fitted to.
In addition, the extended portion 47 is formed so as to be fitted into the lock space 38 of the fitting recess 35.

A pair of tapered surfaces 47 a and 47 a (see also FIG. 4B) are formed at the tip of the extended portion 47. The inclination of the pair of tapered surfaces 47a, 47a is matched to the inclination of the pair of tapered surfaces 39, 39 of the fitting recess 35.
A width W3 of the extended portion 47 is formed slightly smaller than a width W2 of the lock space 38, and a width W4 of the neck portion 46 is formed slightly smaller than the gap S between the pair of projecting pieces 37, 37.
Accordingly, the fitting convex portion 42 of the lip portion 32 can be fitted and coupled to the fitting concave portion 35 of the frame portion 31.

A hollow portion 48 is formed in the fitting convex portion 42, specifically, substantially at the center of the extended portion 47, thereby improving the deformability of the extended portion 47.
Thereby, the fitting convex part 42 of the lip part 32 can be easily and reliably fitted to the fitting concave part 35 of the frame part 31.

The lip body 43 is formed in a substantially curved shape so as to extend along the slide side door 12 and slightly protrude toward the slide side door 12. The convex portion 43 a of the lip main body 43 is formed so as to contact the inner surface 12 a of the slide side door 12.
As the resin material of the lip portion 32, a material having a low friction coefficient, for example, a chlorinated ethylene copolymer crosslinked product “Alclin” (registered trademark; manufactured by DuPont) is used, but is not limited thereto.

  When the vehicle window glass structure 20 thus configured is attached to the vehicle 10, an adhesive 49 is applied to the back surface 21 a of the quarter window glass 21 and in the vicinity of the frame portion 31, and the adhesive 49 is interposed therebetween. The quarter window glass 21 is attached to the panel 51 of the vehicle 10.

FIG. 3 is a perspective view showing a state in which the frame portion and the lip portion according to the first embodiment of the present invention are disassembled.
The vehicle window glass structure 20 includes a front molding 23 on the front edge 22 of the quarter window glass 21, and an upper molding 27 and a lower molding 28 on the upper edge 24 and the lower edge 25, respectively.
The upper end 52 of the frame 31 constituting the front molding 23 is formed flush with the upper side 27a of the upper molding 27, and the lower end 53 of the frame 31 is formed flush with the lower side 28a of the lower molding 28.

The outer peripheral portion 33 of the frame portion 31 is provided with a step portion 34 and a fitting concave portion 35.
By forming the fitting recess 35 with a length L1 smaller than the length L2 of the frame portion 31, the upper end 35a of the opening of the fitting recess 35 is arranged on the inner side of the upper end 52 of the frame portion 31, and the fitting recess 35 The lower end 35 b of the opening is arranged inside the lower end 53 of the frame portion 31.

The upper end 35a of the fitting recess 35 is closed by the upper end 52 of the frame portion 31, and the fitting recess 35 is hidden so that it cannot be seen. In addition, the lower end 35 b of the fitting recess 35 is closed by the lower end 53 of the frame portion 31 so that the fitting recess 35 is hidden from view.
Here, when the frame portion 31 is formed of soft vinyl chloride as an example, it is preferable to set the thickness t of the upper and lower ends of the frame portion 31 to about 2 mm, but the thickness t is not limited to this. Absent.

The length L3 of the fitting convex portion 42 of the lip portion 32 is formed slightly smaller than the length L1 of the fitting concave portion 35 of the frame portion 31.
Thereby, the fitting convex portion 42 of the lip portion 32 can be fitted into the fitting concave portion 35 of the frame portion 31.
At this time, the appearance can be enhanced by hiding the upper and lower ends 54 and 55 of the fitting convex portion 42 of the lip portion 32 so as not to be seen by the upper and lower ends 52 and 53 of the frame portion 31.

Next, the manufacturing process of the window glass structure 10 for vehicles is demonstrated based on FIGS.
4 (a) and 4 (b) are diagrams illustrating a process for manufacturing the frame portion and the lip portion according to the first embodiment of the present invention.
In (a), the quarter window glass 21 is disposed in the mold by clamping a forming mold (not shown), and the front edge 22 of the quarter window glass 21 is disposed in a cavity (not shown) of the mold. To do.
By filling the cavity with molten resin (soft vinyl chloride), the frame portion 31 is integrally formed on the front edge 22 of the quarter window glass 21.
The mold is opened and the quarter window glass 21 provided with the frame portion 31 is taken out of the mold.

In (b), a billet (chlorinated ethylene copolymer cross-linked product “Alcrine” (registered trademark; manufactured by DuPont)) is placed in an extrusion mold (not shown), and the billet is extruded by a plunger of the extrusion mold. Passes through the die.
At this time, the billet is extruded and formed on the lip portion 32.

FIGS. 5A to 5C are views for explaining a process of assembling the lip portion to the frame portion according to the first embodiment of the present invention.
In (a), a lubricant (for example, water + ethanol) is applied to the fitting recess 35 of the frame portion 31. Next, the fitting convex portion 42 of the lip portion 32 is moved as shown by the arrow a toward the fitting concave portion 35 of the frame portion 31.

In (b), the tapered surfaces 47 a and 47 a of the fitting convex portion 42 are brought into contact with the tapered surfaces 39 and 39 of the fitting concave portion 35. In this state, the base 41 is pressed by a roller (not shown) or the like with the pressing force of the arrow F1.
As a result, the pair of projecting pieces 37 and 37 are elastically deformed as shown by the arrow b, and the gap S (see FIG. 2) between the pair of projecting pieces 37 and 37 is greatly widened.

At the same time, the extended portion 47 of the fitting convex portion 42 is elastically deformed as shown by an arrow c.
Here, by forming the hollow portion 48 in the fitting convex portion 42, it is possible to improve the deformability of the fitting convex portion 42, that is, the expansion portion 47. As a result, the width W3 (see FIG. 2) of the extended portion 47 is reduced.
In addition, by applying a lubricant (for example, water + ethanol) to the fitting concave portion 35 of the frame portion 31, the fitting convex portion 42 slides with respect to the fitting concave portion 35.

In (c), in particular, the hollow portion 48 is formed in the fitting convex portion 42 to enhance the elastic deformability of the expansion portion 47, so that the fitting convex portion 42 can be easily and surely fitted into the fitting concave portion 35. Include.
By fitting the fitting convex portion 42 into the fitting concave portion 35, the extended portion 47 of the fitting convex portion 42 enters the locking space 38 (see (a)) of the fitting concave portion 35.

The projecting pieces 37 of the fitting concave portion 35 sandwich the neck portion 46 of the fitting convex portion 42 and hold the expansion portion 47 in the lock space 38 (see (a)).
Therefore, the pair of protrusions 37, 37 prevent the extended portion 47 from coming out of the fitting recess 35, that is, the lock space 38.
As a result, the lip portion 32 is prevented from slipping out of the frame portion 31, and the lip portion 32 is securely fitted and coupled to the frame portion 31.

  In the present embodiment, the content of applying the lubricant (for example, water + ethanol) to the fitting recess 35 of the frame portion 31 is illustrated in (a), but the lubricant is applied to the fitting recess 35 of the frame portion 31. It is also possible to fit the fitting convex portion 42 into the fitting concave portion 35 without applying.

  Returning to FIG. 2, according to the glass window structure 20 for a vehicle of the first embodiment, the lip portion 32 is a separate member from the frame portion 31, and the lip portion 32 is fitted and coupled to the frame portion 31. did. Therefore, it is not necessary to select a material having high weldability with respect to the frame portion 31 as the lip portion 32, and it is possible to select only a material having a low friction coefficient.

By selecting a material having a low coefficient of friction as the lip portion 32, it is possible to suppress abnormal noise generated by the lip portion 32 and the slide side door 12 of the vehicle 10 rubbing against each other.
Moreover, since it is sufficient to provide only a material having a low friction coefficient as the lip portion 32, the material of the lip portion 32 can be easily selected, and the degree of freedom in design can be increased.

Furthermore, since it is only necessary to provide the lip portion 32 with a material having a low friction coefficient, an inexpensive material can be selected.
In addition, since the lip portion 32 is a separate member from the frame portion 31 and the lip portion 32 is fitted and coupled to the frame portion 31, only the lip portion 32 is replaced if the lip portion 32 is damaged. can do.

By fitting the fitting convex portion 42 of the lip portion 32 into the fitting concave portion 35 of the frame portion 31, the lip portion 32 can be coupled to the frame portion 31 relatively easily and reliably.
By the way, in order to form the fitting recess 35, a pair of wall portions are required on both sides. For this reason, in order to form the fitting recess 35, it is necessary to secure a relatively large portion. On the other hand, the fitting convex portion 42 only needs to form a protrusion, and therefore can be formed in a relatively small portion compared to the fitting concave portion 35.
Therefore, the fitting concave portion 35 is formed in the frame portion 31 having a width W 1 larger than that of the lip portion 32, and the fitting convex portion 42 is formed in the lip portion 32.
Thereby, the recessed part 35 for fitting and the convex part 42 for fitting can be formed in a suitable shape.
