Abstract

PURPOSE:To enable visibility to become wider allowing the surface of a door glass to fall in the same plane as that of the outer panel by securing one end of a guide shoe on both sides of the glass with a pin allowing the other end of the shoe to be fitted slidably into a guide channel through a door glass seal. CONSTITUTION:A guide shoe 2 is fixed on the front and rear ends of a glass by means of a pin 5 through a clapper 4 which projects as an integral part from the guide shoe 2 itself against the glass 2. An end section 6 of the shoe which offsets to a cabin side from the outside of the shoe 2 in regard to a vehicle, is fitted into a groove. Here, the groove is formed by a door glass seal 9 which is fitted to a flange section 14 of a door glass lift guide channel 12. And the end section of the shoe is allowed to move slidably up and down. A trim molding 7 not only covers the flange section 13 of a door outer panel 15, but also overlaps both the periphery of the glass 1 and the outside of the end section 5 of the shoe 2 so as to allow a maze to be formed preventing injected water from blasting directly against the seal 9.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an automobile door window glass device that is fitted and guided by a guide channel to move up and down, and particularly relates to an automobile door window glass device that moves up and down while being fitted and guided by a guide channel. The present invention relates to a door window glass device for an automobile that eliminates the step between the windows and forms a smooth curved surface.

[Conventional technology]

As shown in FIG. 12, a conventional automobile door window glass device has a structure in which the end of the door glass 1 is directly fitted into a guide channel 12 constituting the door frame to move up and down. The outer surface is necessarily recessed from the outer surface of the door frame, ie the door skin surface 15, and there is a considerable step difference between the glass 1 and the skin surface 15.

In order to reduce this difference in level, as shown in FIG. 13, a door window has been developed in which the peripheral edge of the door glass 1 is sandwiched between one end of a guide shoe 2, which has a generally inverted cross-section, and held firmly therein. Glass devices have been proposed. (For example, Utility Model Application Publication No. 56-85520, Utility Model Application Publication No. 56-14
(Refer to Publication No. 3475) [Problems to be Solved by the Invention] However, in such a door window glass device where there is a considerable step between the glass surface and the outer surface of the door, it is difficult to maintain the smooth appearance of the automobile body surface. In addition to the loss of continuity and integrity, the airflow around the surface of the vehicle body is disturbed and vortices are generated when the vehicle is running, resulting in increased air resistance of the vehicle body and problems such as the generation of so-called wind noise.

Further, in the case of a device having a small step difference as shown in FIG. 13, a new problem arises in that the width of the window frame becomes large and the field of view becomes small, as shown by W' in the figure.

Therefore, the present invention eliminates the level difference existing between the automobile door window glass surface and the outer panel surface of the automobile body, and arranges both on the same surface as much as possible to form a continuous and smooth curved surface of the entire automobile. The purpose is to

[Means for solving problems]

In order to achieve the above object, according to the present invention, the outer surface of the door glass is covered over the entire four peripheral areas of the upper, lower and both sides, the outer surface of the door frame, and the outer surface of the door belt line (door outer surface). An automobile door window glass device arranged substantially on the same plane as the
The door has tapered guide shoes that are narrow at the top and wide at the bottom fixed to both sides of the lath by pins at one end, and the other ends of the guide shoes are fixed in the door glass lifting guide channel formed in the door frame. Provided is a door window glass device for an automobile, which is slidably fitted to the door glass through a door glass seal.

[Effect]

In the automobile door window glass device of the present invention, the door glass and the guide shoe are fixed to each other through the bottle, and the door glass is not fixedly held by only one end of the guide shoe. That is, the guide shoe does not have the function of firmly holding the door glass, or does not have the function of holding the door glass firmly, or -
The wearing function is almost completely entrusted to the pin. As a result, in the present invention, it is possible to maintain a wide field of view and to make the door glass substantially flush with the outer surface of the door.

〔Example〕

Next, the present invention will be explained in more detail based on examples.

1 to 5 show one embodiment of the present invention.

FIG. 1 is a sectional view taken along line A-A in FIG. 6,
(In addition, □Figure 6 is a schematic diagram of an automobile.) The guide shoe 2 does not fix or hold both sides of the glass 1 only by the portion 5 which is this one end, and the guide shoe 2 does not fix or hold the glass 1 on both sides. 1. It is fixed to the front and rear end surfaces of the glass at a total of 4 places on the top and bottom respectively through the tongue-like piece 4 that protrudes integrally from the main body of the guide shoe 2 to the glass 1 by the kin 3 without being fixed by sandwiching both sides. has been done. The part 5 of the guide shoe 2 that contacts the side edge of the glass 1 increases the stability of the shoe 2 fixing to the glass 1, but in order to reduce the width W, the part 5 is removed and the part 5 is removed. There is no problem with the minute extending the last 1. Shoe 20 End part 6 offset to the outside of the vehicle (X in the figure) or to the inside of the cattle compartment (Y)
The door glass is slidably raised and lowered by fitting into a groove formed by a door glass seal 9 attached to the flange portion 14 of the ID channel A/12. The trim molding 7 covers the flange 13 of the door outer panel 15 constituting the door frame, and also extends around the peripheral edge of the glass 1 and the outside of the end 5 of the shoe 2 to prevent water jets from high-pressure car washing etc. from forming on the door glass seal 9. A labyrinth is constructed to prevent the part from being hit directly, and at the same time the glass seal 9 is held. The lip 8 of the glass seal 9 lightly contacts the side surface of the shoe 2 to prevent water and dust from entering, and when a high-pressure jet hits, the contact pressure of the seal lip 8 increases in proportion to the jet pressure to maintain watertightness. . 10 is another core material of the wire carrier, and the flange 14 is sandwiched therebetween. 11 is a pile fabric for ensuring sliding properties and airtightness.

Although the 7-lantern 13 is configured to be shorter than the flange 14, its purpose is to make the width dimension W as small as possible in terms of appearance.

FIG. 2 is a sectional WJ diagram taken along line BB in FIG. 6, and the door glass seal 9 has the same constant cross section as in FIG.
The offset dimension 81 from the surface of the glass 1 to the center line of the end 6 of the shoe 2, that is, the center line 21 of the door glass seal, is larger than the offset dimension 8u in FIG.

Reference numeral 15 denotes a door outer panel that constitutes the door frame, and as shown in the figure, the level difference between the outer surface of the outer panel 15 and the outer surface of the door lath 1 is extremely small. Reference numeral 16 designates another tongue-shaped piece protruding from the shoe 2, but it is located below the door belt line, so it is not visible from the outside.

FIG. 6 is an overall view of the shoe 2, where the two-dot chain line indicates the door glass 1 and the hatched area indicates the cross-sectional shape of the shoe 2.

The shoe 2 as a whole has a tapered shape that becomes wider from the top toward the bottom. Basically, the shoe 2 is fixed to the glass 1 by a bottle connection via the tongues 4 and 16, but it is also possible to use adhesive, sealer, etc. on the contact surface between the shoe 2 and the glass 1. .

FIG. 4 is a sectional view taken along line CC in FIG. 6,
17 is Uniday seal, 18 is trim molding,
19 is the primary seal ridge, 20 is the secondary
It is a seal lip. The trim molding 18 is integrally molded with the weather seal 17 to prevent the glass 1 from moving to the outside of the vehicle, and overlaps the edge of the glass 1 to prevent water from directly hitting it.

The primary seal lip 19 smoothly moves upward and deforms while contacting the inside of the trim molding 18 with its tip, follows the rise of the glass, and exerts a sealing force by contacting the upper end of the glass 1, and its deflection amount is several seconds. It absorbs errors in IJ and each component and maintains sufficient airtightness over the entire length of the top of the glass.

FIG. 5 is a sectional view taken along line DD shown in FIG. 6. 1
5 is the door outer panel, 23 is the door inner trim panel,
24 is the door belt line out of town strip,
Reference numeral 25 indicates a door belt line inner sea urchin strip, and reference numeral 26 indicated by a two-dot chain line indicates a state in which the door glass 1 is lowered to the lowest position, whereas the glass shown in 1 indicates a state in which it is raised upward to the maximum extent and is completely closed. 27 and 28 are pile fabrics. The solid line of the belt line sea urchin strip 24.degree. 25 shows the state of contact with the closed glass, and the shape shown by the two-dot chain line shows the state of contact with the lath when it is lowered to the lowest position.

Since the shoe 2 is vertically wedge-shaped, the sea urchin strips 24 and 25 constantly follow the lateral movement of the glass that occurs in the direction perpendicular to the vertical movement of the glass, that is, in the left and right directions, and come into contact with the inner and outer surfaces of the glass. It can be kept airtight. The sea urchin strips 24 and 25 are made into a loop shape to increase the restoring force to the initial shape.In the case of the outer sea urchin strip 24, by rolling up the lower half of the loop, and in the case of the inner sea urchin strip 25, allows for large deformations by folding the upper half of the loop.

7 to 9 show another embodiment of the present invention.
The figure shows the glass 1 further extended to the outside of the vehicle by removing the part 5 of the shoe 2 in Figure 1 to about half the thickness of the glass lath 1.
The outer surface of the trim molding 29 and the outer surface of the door outer panel 15 are completely on the same plane, achieving a so-called full flush glass condition. This is the 6th
This is only possible because the shoe 2 supports the glass 1 only from the inside with the tongue-like piece 4 as shown in the figure.

Further, the width dimension W of the trim molding 29 in FIG. 7 is smaller than the width dimension W of the trim molding 7 in FIG. 1.

FIG. 8 is another example of FIG. 4, and in this case, the bridge-shaped portion 30 forming the hollow corresponds to the Zoraimali Seal Rizzo 19 of FIG.

The seal shown in FIG. 8 is characterized in that the arch-shaped bridge portion 30 bends as shown by the two-dot chain line without undergoing any elongation deformation. Furthermore, since the bridge portion 30 wraps around the upper end of the glass, there is a large contact area and good sealing performance. Also, by inverting the arch shape, a large amount of deflection can be secured.

FIG. 9 is another example of FIG. 5, in which the door belt line outer sea urchin strip 31 is not a loop, but
It has two upper and lower lips 32 and 33. In this case, 33 is a main seal lip, and 32 is a cover lip that assists the main seal lip 33 in maintaining contact with the glass 1 and also has the function of improving the appearance. The reason why the main seal lip 33 has a nearly linear shape is to prevent the lip 33 from buckling and deforming due to the frictional force between the lath 1 and the tip of the lip 33. Furthermore, since the lip 33 is in contact with the glass surface at an angle close to parallel, the lip is not rolled up by the glass, and it can easily follow large lateral movements of the glass. Also, the first
In the example shown in FIG.
The shoe 2 in FIG. 1 is fixed as an integral continuous member, and in this case, the added shoe.

Since the glass 34 functions to maintain watertightness and prevent the glass from moving outward, it is possible to expose the glass not inside the trim molding 18 but on the same plane as the trim molding 18.

FIG. 11 shows still another embodiment of the present invention, in which a guide shoe 35 having an inverted U-shaped cross section is attached to the outer flange 13 of the guide channel 12, and a tongue-like shape protrudes from an appropriate position of the guide shoe 35. Both sides of the door glass are fixed to the bin 3 via the pieces 4, and the glass 1 is extended to the end face.

Since the present invention has the configuration and operation as explained above,
It has the following unique effects. (1) The level difference between the car body and the door glass surface is minimized or zero, improving the appearance.

++) Reduced air resistance, increased top speed, and reduced fuel consumption.

'm) Air noise during driving is reduced.

iv) Width of the window frame member around the door glass, i.e., Fig. 1;
The dimension W illustrated in Fig. 7 etc. is the width of the same type of conventional one aiming for flushing as illustrated in Fig. 13. □ Effective glass area is large, visibility is widened, the interior of the vehicle is bright, and the exterior appearance is also improved. do.

■) At the upper horizontal part where the door window touches the roof and the vertical part where it touches the front, middle and rear pillars, the door glass is flush with the surface of the vehicle body, as well as the door belt line. That is, even at the section D-'D in FIG. 6, it is possible to position the glass much closer to the door panel outer panel surface than in the prior art configuration. In other words, the glass and the vehicle body surface are on the same surface over the entire periphery of the four sides of the door glass.

V+) The number of parting lines for parts, which are normally 3 to 4, is reduced to 2, improving the appearance.
