Description

[Detailed Description of the Invention] [Industrial Field of Application] This invention relates to a door glass structure that is inserted and guided in a vertically slidable manner into a door frame disposed on a door of, for example, an automobile.

[Conventional technology]

Conventionally, as a door and door glass structure of an automobile, etc., for example, a structure of a vehicle with a door frame in which a door frame having substantially the same external shape as the door glass is fixed to the upper part of the door is taken as an example. As shown in FIG. 8 and FIG. 8, a door frame 1 having substantially the same external shape as the door glass 30 is fixed by welding or the like between the door outer panel and the door inner panel that constitute the door D. As shown in FIG. 8, a door glass run 20 having a U-shaped cross section is fitted into the door frame 1, and a door glass 30 is inserted and guided into the door glass run 20 so as to be slidable up and down. That is, the door frame 1 has a front side 11a and a rear side 11b which are arranged substantially parallel to each other at intervals in the longitudinal direction of the vehicle so as to have substantially the same external shape as the door glass 30, and an upper side connecting these sides. 12, and each of these sides 11a, 11b,
A door glass run 20 having a U-shaped cross section is fitted into a door frame 1 consisting of 12 parts. By inserting the front side 310a and the rear side 310b, which are the vertical sides 310, the door glass 30 is inserted and guided in the door frame 1 (inside the door glass run 20) so as to be slidable up and down. Further, when the door glass 30 is closed, the upper side 320a of the lateral side 320 of the door glass 30 is inserted (inserted and guided) into the door glass run 20 fitted to the upper side 12 of the door frame 1. . In this way, the door glass 30 is inserted and guided so as to be vertically slidable into the door glass run 20 fitted to the door frame 1 (front side 11a and rear side 11b). ), the door frame 1 (door glass run 2
0) It has a structure that allows it to move up and down by sliding up and down inside. That is, as shown in FIG. 7, the regulator handle 14 on the passenger compartment side is attached to the regulator 13.
When the regulator arm 15 is rotated, the regulator arm 15 rotates (swings), and the channel 16 is moved in the vertical direction.
The door glass 30 whose lower side 320b, which is 0, is fixed, is moved up and down (sliding up and down).
It is something that goes up and down. In this case, the door glass 3
The front side 310a and the rear side 3 which are the vertical sides 310 of 0
10b is supported in the vehicle longitudinal direction or the vehicle width direction by the door glass 30 fitted to the front side 11a and rear side 11b of the door frame 1, as shown in FIG. (The front side 11a and the rear side 11b) are slidably guided (that is, moved) in a direction along the front side 11a and the rear side 11b.

The shape of the door glass 30 configured in this way (external shape in side view) differs depending on the vehicle, but generally it is a modified pentagon (mainly used for the front door) or a pentagon as shown in FIG. It is formed into a substantially parallelogram shape (mainly used for rear doors) as shown in Fig. 10, and the configuration shown in Fig. 7 described above is for a rear door. The formed door glass 30 is used.

The door glass 30 having such a shape has a front side 310a, which is the vertical side 310, and a rear side 31.
0b is inserted into the door glass run 20 fitted to the front side 11a and the rear side 11b of the door frame 1, and is supported by the door glass run 20 as shown in FIG. The door glass 30 comes into direct contact with the door glass run 20 and is slid and guided up and down so that it is slid (moved) in the direction along the side 11a and the rear side 1b. )
It is something. That is, when the door glass 30 slides up and down (opening and closing), the door glass 30 (the front side 310a and the rear side 310b, which are the vertical sides 310) moves toward the door frame 1 (the front side) as shown in FIG. It slides in direct contact with the door glass run 20 fitted on the side 11a and the rear side 11b), and during this vertical sliding, the door glass run 20 (particularly in FIGS. 9 to 11) Each corner 4 forming the outer shape of the door glass 30 as shown in FIG.
0) and the door glass run 20 (a weather strip attached to the vehicle body in door frameless vehicles that do not have the door frame 1 on the upper part of the door D). In order to reduce the force required to lift and lower the door glass 30 during movement, the steps shown in FIGS.
As shown in Fig. 1, each corner 40 (40a to 40d) forming the outer shape of the door glass 30 is formed into a rounded shape (generally a simple radius with a radius of about 5 mm) by chamfering, that is, rounded. It is configured to be formed into a rounded shape.

Further, as shown in FIG. 6, the door glass 3
The fulcrum 70 that supports the door glass 30 of the channel 16 in the regulator mechanism that is raised and lowered (to which lifting force is applied to raise and lower it) is:
Due to constraints of each structural component inside the door D, it is often impossible to match the center of gravity of the door glass (so-called center of gravity of the door glass) 80, and the fulcrum 70 of the door glass 30 is located at the front and back of the vehicle with respect to the center of gravity of the door glass 30. In most cases, the direction is shifted. In the prior art shown in FIGS. 4 to 7, the fulcrum 70 of the door glass 30 is deviated from the center of weight of the door glass 80 toward the rear of the vehicle. Furthermore, the direction in which the door glass 30 is raised and lowered by the regulator mechanism (the direction in which the raising and lowering force is applied) is the vertical (vertical) direction A, which is the vertical direction of the vehicle. As shown in FIG. 7, the side 11a and the rear side 11b are inclined so that their lower sides face the front of the vehicle (that is, the entire front side 11a and rear side 11b of the door frame 1 are inclined backward). , the direction in which the door glass 30 vertically slides (moves) within the door frame 1 (door glass run 20) by the regulator mechanism is along the rearwardly inclined door frame 1 (front side 11a and rear side 11b). It is in the diagonal direction B, which is different from the above-mentioned lifting direction A of the door glass 30 (vertical direction where lifting force is applied).

Furthermore, the front side 310 of the door glass 30
a and the rear side 310b, and this door glass 30
The door glass run 20 fits into the front side 11a and the rear side 11b of the door frame 1, in which the front side 310a and the rear side 310b are inserted and guided.
(U-shaped base) and each part (door glass 30, door frame 1, door glass run 20)
A certain gap 90 is provided as shown in FIG. 6 to absorb product errors and assembly errors (such as ).

Therefore, as described above, when the door glass 30 slides up and down (up and down), the door glass 30 does not slide in the vertical direction but in an oblique direction. Door glass 3 as shown
In a configuration in which the fulcrum 70 of the door glass 0 is shifted toward the rear of the vehicle from the door glass center of weight 80, the door glass 30
When rising, the door glass 30 slides (rises) in a forward tilted state (so-called forward leaning) as shown by arrow C in FIG. (so-called backward movement) and slides (descends).

In addition, in order to prevent the door glass from hitting the door frame or the door glass run and being unable to close completely when the door glass is closed with the door glass being eccentric when the door glass is opened, A configuration in which the vertical and upper sides of the glass are slightly inclined with respect to each side of the door frame to create a difference between the door glass and the door frame (i.e., a configuration in which the shape of each side of the door glass is changed)
For example, as a conventional technology showing this,
There is a published publication (Utility Application No. 52-89846).

[Problem that the invention attempts to solve]

However, in the case of the door and door glass structures shown in FIGS. 5 to 11, when the door glass 30 slides up and down (ascends and descends), the door glass 30 is not aligned vertically, but rather the door frame 1 tilts backward. (the front side 11a and the rear side 11b), and the gap 90 provided between the door glass run 20 fitted to the door frame 1 and the door glass 30. ), and supports the door glass 30 of the channel 16 as shown in FIG.
In order to close the door glass 30 in a configuration where the door glass 30 is located on the rear side of the vehicle (shifted) from 0, the door glass 30
5, the door glass 30 moves toward the front of the vehicle by the gap 90 (see FIG. 6) with the door glass run 20, as shown by arrow C in FIG. When the door glass 30 is raised in such a state, the entire front side 310a and rear side 310b of the door glass 30 will come into direct contact with the door glass run 20. Instead, what comes into direct contact with the door glass run 20 are the upper corner 40a of the front side 310a and the lower corner 40b of the rear side 310b of the door glass 30, which are in a forward inclined state (leaning forward). corner 40a,
Although 40b is formed in a rounded shape, it is a simple radius with a radius of about 5 mm, for example, as shown in FIG.
a), the upper corner 40a of the front side 310a of the door glass 30 is shown.
0a (simple rounded shape) is the door glass run 2
0, and due to this point contact (point contact), the corner portion 40a
The sliding contact force (sliding surface pressure) with the door glass run 20 concentrates on the door glass run 20.
b), the sliding resistance between the door glass 30 (corner portion 40) and the door glass run 20 increases, and the lifting operation load of the door glass 30 increases, thereby reducing the liftability of the door glass 30. decreases. Further, due to the point contact (point contact) of each of the corners 40a, 40b with the door glass run 20 and the concentration of sliding contact force (sliding surface pressure) caused by this, when the door glass 30 is raised, the corner portions 40a,
40b may get caught (so-called stuck) on the door glass run 20, which further increases the sliding resistance as described above (further reduces the ability of the door glass to rise), and the door glass run 20
This door glass run 2 due to wear itself
The durability of 0 is reduced.

In addition, in order to open the door glass 30, the door glass 3
Although not shown, when lowering the door glass 30, contrary to the above-mentioned raising of the door glass 30,
moves toward the rear of the vehicle and descends in a backward tilted state (so-called backward tilt), so that the lower corner 40c of the front side 310a and the upper corner 40d of the rear side 310b of the door glass 30 are aligned with the door. This directly contacts the glass run 20, and causes the same problem as when the door glass 30 is raised (shown in FIGS. 4 and 5) as described above. Also, a fulcrum 7 that supports (raises and lowers) the door glass 30
Even if the door glass 3 is located (deviated) toward the front of the vehicle from the door glass center of gravity
0 movement is opposite to the configuration shown in FIGS. 4 to 6 described above, but when the door glass 30 slides up and down (when going up and down), it is similar to the configuration shown in FIGS. 4 to 6 described above. This will cause problems.

Here, in order to prevent such a problem, in order to soften the point contact (point contact) between each of the simple rounded corners 40 of the door glass 30 and the door glass run 20 (to reduce sliding resistance). Therefore, instead of making each corner 40 of the door glass 30 into a small simple radius with a radius of about 5 mm,
It is conceivable to create a simple radius with a large radius (increase the simple radius of each corner 40), but if the radius of each corner is too large, the door glass 3
0 When the door glass 30 is fully closed, each corner 40 of the door glass 30 with a large simple radius can reliably and sufficiently enter (retain) each corner of the door glass run 20 fitted to the door frame 1. This may cause problems such as water leakage and wind noise due to the reduced sealing performance. It cannot be formed.

In addition, in a so-called door frameless vehicle that does not have the door frame 1 above the door D, the upper part of the door D (above the door belt line) is the door glass 30.
The door D slides (seals) by coming into direct contact with the weather strip attached to the vehicle body.Although not shown, the interior of the door D (below the door belt line) is approximately parallel to the weather strip at intervals in the longitudinal direction of the vehicle. A lower door frame is arranged opposite to the lower door frame, and the door glass 30 (the front side 310a and the rear side 310b, which are the vertical sides 310) is vertically slidably inserted into the door glass run fitted to each of the lower door frames. The support structure and movement of the door glass 30 inside the door D (each lower door frame) are shown in FIGS. In the case of the door glass 30), the configuration is approximately the same as that shown in
When the door glass 30 of a door frameless vehicle that does not have such a door frame 1 slides up and down (raises and lowers), the inside of the door D (between each lower door frame) as shown in FIGS. The same problem occurs as in the case of the vehicle with a door frame shown in FIG.

Further, in the above explanation, the case of a rear door in which the door glass 30 formed in the substantially parallelogram shape shown in FIG. In the case of the door glass 30 in the door, the structure is exactly the same as that described above (shown in FIGS. 4 to 8), and similar problems occur.

That is, a fulcrum 70 that supports (raises and lowers) the door glass 30 and a center of gravity (center of gravity) 80 of the door glass.
and the direction A in which the door glass 30 is raised and lowered by the regulator mechanism (direction in which lifting force is applied) and the direction in which the door glass 30 actually slides (moves) up and down within the door frame 1 (door glass run 20). As long as B does not match, the above-mentioned problems may occur when the door glass 30 slides up and down (as it goes up and down), and it is impossible with the current car body structure to match each of the above conditions completely. be.

Therefore, the purpose of this invention is to reduce the sliding resistance between the door glass and the door glass run when the door glass is raised and lowered, reduce the force required to raise and lower the door glass, and improve the operability of raising and lowering the door glass. The goal is to improve durability.

[Means for solving problems]

Therefore, this idea solves the above problem by forming the corner of the door glass that comes into contact with the door glass run when the door glass is raised and lowered into an approach radius shape with a large curvature from the vertical side to the horizontal side of the door glass. At the same time, the problem is to be solved by connecting the approach radius of this corner and the lateral side of the door glass with a simple radius of small curvature.

More specifically, referring to the reference numerals shown in FIG. 1, there is a front side 31a and a rear side of 31b (see Figure 2)
vertical sides 31 and each of these vertical sides 31, 31a, 31
In a door structure in which a door glass 3 consisting of horizontal sides 32 such as an upper side 32a and a lower side 32b (see FIG. 2) connecting the edges 3 and 3 is inserted and guided so as to be vertically slidable, the corners forming the outer shape of the door glass 3 Part 4
(corner 4a at the top of the front side 31a of the door glass) is cut into an approach round shape with a gentle large curvature little by little from the vertical side 31 to the horizontal side 32 of the door glass 3. An approach radius portion 5 is formed at the door, and the approach radius portion 5 and the horizontal side 32 of the door glass 3 are connected by a simple radius portion 6 having a small curvature.

[Effect]

According to the above-mentioned means, the door glass 3 comes into direct contact with the door glass run 2 when the door glass 3 is raised or lowered.
A large curvature cut is cut into the corner portions 4, 4a of the door glass 3 from the vertical side 31 (front side 31a) to the horizontal side 32 (upper side 32a), forming the corner portions 4, 4a. An approach radius portion 5 is formed, and the corner portions 4, 4a of the door glass 3 are formed by connecting the approach radius portion 5 and the horizontal sides 32, 32a of the door glass 3 with a simple radius portion 6 having a small curvature. By doing so,
When the door glass 3 moves up and down, for example, if the door glass 3 moves as shown by the arrow C in FIG. The approach radius portion 5 having a large curvature formed at the corner portion 4a and the lower corner portion 4b of the rear side 31b shown in FIG. 2 comes into direct contact with and slides on the door glass run 2, The point contact (point contact) between this door glass run 2 and the approach radius portion 5 of the corner portions 4, 4a, 4b of the door glass 3 can be softened, that is, it can be brought closer to a line contact, and the contact area can be reduced. This can increase the sliding contact force (sliding surface pressure) that acts on the approach radius portion 5 of the corner portions 4, 4a, 4b of the door glass 3.
can be dispersed to some extent, so the door glass 3 (each corner portion 4a, 4b) can smoothly slide up and down within the door glass run 2,
The sliding resistance between the door glass 3 and the door glass run 2 can be reduced to improve the operability of raising and lowering the door glass.
Since the (approach radius portion 5) does not get caught (so-called pecking) on the door glass run 2, the door glass run 2 is prevented from getting caught (so-called pecking) on the door glass run 2, which reduces sliding resistance as described above. 4 U, 4
The wear caused by b) can be reduced, and the durability of the door glass run 2 can be improved.

〔Example〕

Hereinafter, embodiments of this invention will be described based on the accompanying drawings.

The drawings from Fig. 1 to Fig. 3 show an embodiment of this invention, and take as an example the configuration of a rear door on the rear side of the vehicle side in a vehicle with a door frame fixed to the upper part of the door. To explain, as shown in FIGS. 2 and 3, a door frame 1 having substantially the same external shape as the door glass 3 is fixed to the upper part of the door D body, and a cross section is formed inside the door frame 1. A U-shaped door glass run 2 is fitted, and the front side 11 of the door frame 1 into which this door glass run 2 is fitted.
The front side 31a and the rear side 31b are inserted and guided by the vertical side 31 of the door glass 3 into the door glass run 2 at the a and rear sides 11b, and the door glass 3 is inserted and guided so as to be slidable up and down. This is what is being done. Also, when the door glass 3 is closed, the upper side 32a is the horizontal side 32 connecting the vertical sides 31 (front side 31a and rear side 31b) of the door glass 3.
is inserted (inserted and guided) into the door glass run 2 fitted on the upper side 12 of the door frame 1. and door glass 3
When the door glass 3 is raised and lowered to open and close, the regulator mechanism (numerals 13 to 16) moves the door glass 3 (the front side 31a and the rear side 31b, which are the vertical sides 31) to the door frame 1 (the front side 11).
The door glass 3 is configured to be raised and lowered by sliding up and down along the door glass run 2 (inside the door glass run 2 fitted to the rear side 11b).

In the door and door structure constructed in this way, as shown in FIGS. 1 and 2, corner portions 4 of the door glass 3 (door glass 3 from the vertical side 31 to the horizontal side 32 of the door glass 3 forming the corner 4,
That is, as shown in the enlarged view of FIG. 1, in the case of the upper corner 4a of the front side 31a of the door glass 3, from the front side 31a which is the vertical side 31 of the door glass 3 toward the upper side 32a which is the horizontal side 32. , by cutting (i.e., cutting off) into a so-called approach round shape with a gentle large curvature, this corner 4a (front side 31a
An approach radius 5 with a large curvature is formed at the upper corner 4a), that is, the front side 31 of the door glass 3
a Upper corner 4a from this front side 31a to the upper side 32
In order to form a so-called approach-shaped radius which is gradually cut deeply toward the corner a and slightly sloped into an arc shape, the approach radius 5 is formed in the approach radius 5 formed at the corner 4a. The upper end (that is, the end on the upper side 32a side that is the horizontal side 32) and the upper side 32a that is the horizontal side 32 of the door glass 3 are connected in a simple rounded shape with a small curvature, that is, a simple rounded part 6 with a small curvature. The corners 4a of the door glass 3 are formed by tying them together. In addition, the front side 31 of this door glass 3
The cut size 10 of the approach radius portion 5 formed at the upper corner portion 4a is the same as that of the door glass 3.
This is determined by the degree of forward inclination (that is, the backward inclination state of the door frame 1, the size of the gap 9 between the door glass 3 and the door glass run 2, etc.). Although FIG. 1 shows the shape of the corner 4a at the upper part of the front side 31a of the door glass 3, the other corners 4b, 4c, and 4d in FIG. and is formed in the simple rounded portion 6).

Similarly to the prior art shown in FIGS. 4 to 8, for example, as shown in FIG. 2, the door glass 3 is supported by the channel 16 (see FIG. 3) in the regulator mechanism (as shown in FIG. The fulcrum 7 (where lifting force is applied) is on the rear side of the vehicle (shifted) from the door glass 3 weight fulcrum (weight) 8
When the door glass 3 rises to close, the front side 11a and the rear side 11b of the door frame 1 are tilted (backwards) as shown in FIG. The door glass 3 moves toward the front of the vehicle by the gap 9 with the door glass run 2 and is in a forward tilted state (so-called forward leaning).
As a result, the upper corner 4a of the front side 31a and the rear side 31 of the door glass 3 are raised (pushed up) and are in this forward inclined state (leaning forward).
b The lower corner 4b directly contacts the door glass run 2 and slides (rises), but each corner 4a directly contacts and slides (slides in contact) with the door glass run 2. , 4b is formed by an approach radius portion 5 with a large curvature and a simple radius portion 6 with a small curvature, for example, the front side 3 of the door glass 3.
Regarding the corner 4a at the upper part of the door glass 1a, as shown in FIG. Since the approach radius portion 5 having a large curvature formed in the door glass run 2 comes into direct contact with and slides on (sliding contact with) the door glass run 2, the upper part of the front side 31a of the door glass run 2 and the door glass 3 The so-called point contact (point contact) with the approach radius portion 5 formed at the corner portion 4a can be softened, that is, the door glass run 2 and the approach radius portion 5 of the corner portion 4a can be brought closer to line contact. At the same time, by softening this point contact (bringing it closer to line contact), the front side 3 of the door glass 3 can be
The sliding force (sliding surface pressure) due to the contact (sliding contact) with the door glass run 2 acting on the approach radius portion 5 formed at the upper corner portion 4a of the door glass run 2 can be dispersed to some extent. Incidentally, when the door glass 3 is raised in a forward inclined state (leaning forward), the lower corner 4b of the rear side 31b of the door glass 3 shown in FIG. 2 also directly contacts and slides on the door glass run 2. ) However, the lower corner 4b of the rear side 31b of this door glass 3 is also the same as the front side 31a.
Like the upper corner portion 4a, it is formed by an approach radius portion 5 and a simple radius portion 6, and the door glass run 2 is the upper corner portion of the front side 31a of the door glass 3 as shown in FIG. It is possible to create a sliding contact state similar to that of 4a.

Therefore, due to the sliding contact between the approach round portion 5 of each corner 4a, 4b of the door glass 3 and the door glass run 2, the door glass 3 (each corner 4a,
4b) can slide extremely smoothly within the door glass run 2 and rise, and the door glass run 3
(each corner 4a, 4b) and the door glass run 2 can be reduced, the lifting operation load (lifting operation force) of the door glass 3 can be significantly reduced, and the so-called door glass run 2 can be reduced. It is possible to significantly improve the lifting operability of No. 3.

Further, each corner portion 4a, 4b of the door glass 3 that comes into sliding contact with the door glass run 2 is formed into an approach round portion 5, and thereby the approach radius portion 5 of each corner portion 4a, 4b and the door glass The point contact (per point) with the run 2 can be softened (can be brought closer to line contact), and the sliding contact force (sliding surface pressure) with the door glass run 2 acting on the approach radius portion 5 can be made softer. ) can be dispersed to some extent, thereby reducing the forward tilting state (leaning forward) of the door glass 3 when the door glass 3 is rising.
Also, each corner 4a, 4 of the door glass 3
b (approach radius portion 5) can be prevented from getting caught (so-called pecking) on the door glass run 2, that is, each corner 4a, 4b of the door glass 3.
(Approach round part 5) The door glass run 2
This reduces the sliding resistance between the door glass 3 (the approach radius 5 of each corner 4a, 4b) and the door glass run 2 (by reducing the lifting force of the door glass 3) as described above. In addition to improving lift operability), the door glass 3
Abrasion of the door glass run 2 due to sliding contact between the approach radius portions 5 of the corners 4a and 4b can be significantly reduced, and the durability of the door glass run 2 can be greatly improved. It is.

Furthermore, each corner 4a, 4b of the door glass 3
(i.e., the upper edge 32a which is the horizontal edge 32 of the door glass 3)
Since the simple radius portion 6 is formed so as to connect the side edge (side end) and the upper side 32a of the door glass 3 with a simple radius of small curvature, this portion (i.e., the simple radius portion 6) is connected to the door glass run 2. Even in the case of sliding contact, the problem of increased sliding contact resistance due to getting caught on the door glass run 2 does not occur at all.

Furthermore, as explained in the problems of the prior art shown in FIGS. 4 to 8, compared to the structure in which the simple radius of the corner 4 of the door glass 3 is simply increased to reduce the sliding resistance. In this invention, as shown in FIGS. 1 and 2, the approach rounded portion 5 is formed in each corner 4a, 4b of the door glass 3 in a manner that is slightly and gently cut into the approach rounded portion 5. In order to form the corner portions 4a and 4b of the door glass 3, the amount of cut (in other words, the amount of cut off) is not so large (the amount of cut can be small due to the approach radius portion 5), so that when the door glass 3 is fully closed, Each corner portion 4a, 4b (approach radius portion 5) of this door glass 3 can reliably and completely enter (retain) each corner portion of the door glass run 2, and the sealing performance will not be reduced. Therefore, problems such as water leakage and wind noise do not occur at all.

In addition, when lowering the door glass 3 in order to open the door glass 3, the above-mentioned (Figs. 1 and 2)
Although not shown, the door glass 3 moves toward the rear of the vehicle, becoming tilted backwards (so-called backward bending) and lowering, contrary to when the door glass 3 rises as shown in FIG. Front side 31a of door glass 3
The lower corner 4c and the upper corner 4d of the rear side 31b directly contact and slide (slide) on the door glass run 2, but each of these corners 4c, 4d
By forming the approach radius portion 5 and the simple radius portion 6 with a small curvature as described above (shown in FIG. 1), the door glass 3 rises as described above (shown in FIGS. 1 and 2). It has the same effect as that and can obtain the same effects.

In addition, the fulcrum 7 that supports the door glass 3 (to which lifting force is applied to raise and lower it) is located (shifted) toward the front of the vehicle from the door glass center of gravity (center of gravity) 8.
In this configuration, the movement (tilting state, etc.) of the door glass 3 is opposite to the configuration shown in FIGS. 1 and 2 described above, but the corners 4, 4a, 4b,
By forming the approach radius portion 5 and the simple radius portion 6 with a small curvature at c and 4d, when the door glass 3 is raised and lowered, it is possible to obtain the same effect as the configuration shown in FIGS. 1 and 2 described above. be.

Furthermore, in the case of a so-called door frameless vehicle that does not have a door frame 1 above the door D, the door glass 3 (approach radius 5 of the corner 4) is attached to the vehicle body at the top of the door frame 1D (above the door belt line). The corner portion 4 of the door glass 3 that comes into sliding contact with the weather strip is formed with an approach radius portion 5 and a simple radius portion 6 with a small curvature. As a result, the sliding movement between the door glass run 2 fitted into the door frame 1 and the door glass 3 (the approach radius portion 5 of the corner portion 4) in the vehicle with the door frame shown in FIGS. 1 to 3 described above is reduced. It has the same effect (movement) as in the case of contact, and the same effect can be obtained even in this door frame-less vehicle. The door glass 3 (front side 31a and rear side 31b) is inserted and guided into a door glass run fitted in each lower door frame disposed in the lower part),
The inside of this door D has the same structure as the door glass 3 that is inserted and guided into the door frame 1 at the upper part of the door D shown in FIGS. 1 to 3 described above. Even inside, the same effects as those of the vehicle with a door frame shown in FIGS. 1 to 3 described above can be obtained.

Furthermore, in the above explanation, FIGS.
As shown in the figure, we have described the case of a rear door in which the door glass 3 formed into a substantially parallelogram is mainly used. In the case of the door glass 3 of the front door to be used, the structure as described above (FIGS. 1 to 3) is used (the corner portion 4 of the door glass 3 is formed with an approach radius portion 5 and a simple radius portion 6 with a small curvature). ), similar effects can be obtained.

[Effect of idea]

As mentioned above, this invention has a corner part that forms the outer shape of the door glass 3 (i.e., a corner part of the door glass that comes into direct contact with the door glass run when the door glass is raised and lowered).
An approach radius with a large curvature is cut gradually from the vertical side to the horizontal side of the door glass to form an approach radius at this corner, and the approach radius and the horizontal side of the door glass are connected. It is connected by a simple rounded part with a small curvature, and when the door glass is raised or lowered, the approach rounded part formed at the corner part of this door glass comes into sliding contact with the door glass run,
The point contact (point contact) between this door glass run and the door glass corner (approach round part) can be softened (it can be brought closer to a line contact),
In addition, since the sliding contact force (sliding surface pressure) can be dispersed, the sliding resistance between the door glass (approach radius of the corner) and the door glass run can be reduced, and the lifting operation load of the door glass can be reduced. (that is, lifting operation force) can be significantly reduced, and the so-called lifting operability can be greatly improved. In addition, since the approach radius of the corner of the door glass comes into sliding contact with the door glass run, it is possible to prevent the corner of the door glass (approach radius) from getting caught (so-called pecking) on the door glass run. Therefore, together with the above-mentioned reduction in sliding resistance, wear of the door glass run due to sliding contact of the door glass run can be reduced, and the durability of the door glass run can be greatly improved. Furthermore, in order to obtain such an effect, the cut amount of the approach radius portion formed at the corner of the door glass is small, so that it can reliably and completely enter the corner of the door glass run when fully closed. The sealing performance between the door glass (approach rounded corner) and the door glass run (corner) is not degraded at all, and water leakage and wind noise can be reliably prevented.
