Description

Detailed Description of the Invention (Field of the Invention) The present invention provides a carrier that is slidably guided along a guide rail that is attached to a window glass, and a carrier that is spaced apart from the guide rail in a direction transverse to the direction of elevation. and at least one window glass guide provided in the vertical direction, and the window glass guide is included in the glass surface and swings perpendicular to the lifting direction at each lifting position of the window glass lifting device. The present invention relates to a window glass raising and lowering device, particularly for automobiles, which prevents the above-mentioned window glass from swinging about its axis as necessary.

(Prior Art) The minimum requirement for the window glass of a window having a window glass lifting device is that a window glass guide is usually provided on the side so that the glass can be raised and lowered in an orderly manner. Such a glazing guide can be constituted by a side rail having a U-shaped cross section that grips the edge of the glazing. However, window glass guides with other configurations are also conceivable; for example, a guide using a carrier that moves along a guide rail has been proposed, and such guides are placed at positions spaced apart in a direction transverse to the lifting direction.
A carrier is provided which is slidably guided along another guide rail and conveys the window glass. This carrier may be installed simply to guide the window glass, or may be used as a window glass gripping member for a power window that constitutes a power transmission element of a window glass lifting device. There is no problem in guiding the window glass by such a window glass guide and carrier as long as the window glass is formed into a flat plate or curved into a cylindrical shape. In other words, the trajectory drawn by the carrier during its vertical movement is equal to the curvature of the window glass along the guide rail at any vertical position, and the portion of the guide rail supporting the carrier at each vertical position is It is always oriented in the same direction as the facing portion of the window glass near the carrier. However, if the trajectory of the carrier does not match the shape or orientation of the window glass, more specifically, if it does not match the intersection curve with the window glass of a cutting plane extending along the guide rail substantially perpendicular to the window glass. , an inclination angle that is constant or varies depending on the elevation position is created between the carrier carrying portion of the guide rail at each elevation position and the window glass near the carrier. Therefore, in order to specify the carrier trajectory and the curvature of the guide rail to be different from the shape of the window glass, it is necessary to In the case of curved window glass, it may be possible to move it without following the cylindrical surface. According to this, for example, it is possible to rotate the window glass just before reaching the closing state and press the window glass against the seal strip disposed on one side, but it is also possible to press the window glass against the seal strip disposed on one side. In a window pane that is curved in shape, the trajectories of two points on the pane (e.g. the attachment points of a pair of carriers) that are spaced apart from each other in a direction perpendicular to the direction of elevation are generally given different shapes and orientations. , when such a glazing is guided by a glazing guide, for example consisting of a U-section rail curved in the form of a corresponding sector arc and gripping the longitudinal edge of the glazing, the carrier spaced apart from the glazing guide is Draw a trajectory with a different curved shape. This means that the orientation of the window pane in each lifting position is determined, in part, by the side pane guides and, in other respects, by the horizontal pane guide groove on the upper edge of the door, and its orientation is determined accordingly. The attitude of the carrier at the time of is oriented, and based on this the carrier trajectory and the curvature of the guide rail, which generally differ in shape as described above, are determined.

(Problems to be Solved by the Invention) Thus, in the conventional window glass lifting device consisting of a combination of a window glass guide and a carrier,
There is a problem in that the shape of the target window glass, the carrier trajectory to be adopted, and the shape and/or orientation of the curved line of the window glass guide are individually determined by the device.

Therefore, in the field of the window glass lifting device, the present invention is capable of running with low friction even when the shape and/or direction of the curved line of the window glass guide and the locus of the carrier are variously different. The main technical problem is to provide a window glass lifting device that can easily raise and lower the window glass.

That is, although it is possible to impart rotatability by constructing the carrier using an elastic intermediate member, for example, a rubber sleeve disposed perpendicular to the window glass surface, there is a window that allows the carrier to be rotated effectively. The company aims to provide glass lifting equipment.

In this regard, if the guide rail has a curvature different from that of the glazing guide, the distance between the guide rail and the glazing guide in each lifting position on the projection plane perpendicular to the given pivot axis. In addition to the change in the angle between the window glass and the guide rail in the vicinity of the carrier, the angle between the window glass and the guide rail in the vicinity of the carrier changes, especially the angle between the window glass and the guide rail on the projection plane perpendicular to the lifting direction. These angular changes caused by the position of the carrier can be accommodated by constructing the guide rail with a member with a Z-shaped cross section and giving the member a corresponding torsion, but in this case, the member has no freedom. The problem is that the carrier to which the pieces are attached is also subject to corresponding torsions when running along the guide rail, and that the production and installation of such guide rails is therefore expensive. Therefore, it is necessary to overcome the problems in this respect as well. Furthermore, it is desirable to provide the carrier with rigidity in other rotational directions.

Even if there is a wide range of manufacturing accuracy, it is necessary to allow the carrier to run along the guide rail with low friction and low noise.

Furthermore, when moving up and down, the angle between the window glass and the second guide rail also changes in the vicinity of the second carrier. It is desirable to be able to cope with the above-mentioned angle change without having to do so.

Furthermore, when the windowpane lifting device has a simple structure, it is desirable that its lifting and lowering movements be performed with low noise, especially without causing damage to the edges of the windowpane.

(Means for Solving the Problems) In order to solve the above-mentioned main problems, the present invention provides, in the field of the above-mentioned window glass lifting device, a carrier movable along the above-mentioned one guide rail. The guide rail can be applied to the window glass at a position that is inclined with respect to the portion of the guide rail that carries the carrier, and is substantially parallel to the window glass surface and perpendicular to the lifting direction. To provide a window glass raising and lowering device which can also perform rotation.

The other problems mentioned above can be solved according to the attached drawings.
As is clearly exemplified by the subsequent detailed description of the preferred embodiments of the invention, the problem is advantageously solved by the measures disclosed in the claims.

(Embodiments) Below, preferred embodiments of the present invention will be described with reference to the accompanying drawings.

1 to 4 are simplified diagrams of a window glass lifting device 10 that is installed inside an automobile door 12 (the right-hand door in the direction of travel) and that moves a window glass 14 in a substantially vertical lifting direction (direction of arrow A in FIG. 1). It is a diagram. In its lowest position, the gas 14 is within the double-walled body of the door 12, the outline of which is shown in phantom in FIGS. 1 and 2. The window pane 14 in its highest position (outlined in solid lines in FIG. 1) closes the window defined when the vehicle door is closed. The window glass 14 appears after being guided as described below, but at that time, the window frame that accommodates the upper edge of the glass when the window is closed is not included.

The window glass 14 has a pair of carriers, namely:
It is guided and slid by the front carrier 16 and the rear carrier 18, and although it is not necessary,
A lip seal extends horizontally across the exit width of the slit 20 at the horizontal edge of the upper part of the door gap for auxiliary guidance. An example of such a sealing lip 22 is shown in FIG.

The pair of carriers 16 and 18 are connected to the guide rail 2.
4 and 26, respectively, in a manner as described below with respect to FIGS. 9 and 10 and FIGS. 11-14, respectively. Both guide rails extend parallel to each other in the direction A, and each rail has a Z-shaped cross section as shown in FIGS. 3 and 4. Rear guide rail 2
6 is a straight guide rail curved along an arc of radius _R1 , and the arc drawn by the guide rail 26 is on a plane equivalent to the plane of the paper in FIG. , parallel to the plane containing the curved arc of the front guide rail 24, and perpendicular to the span between the guide rails 24, 26. Both guide rails 24, 26 according to Fig. 2
The curved lines of are offset with respect to each other. That is, the front guide rail 24 in the illustrated example is similarly curved into an arc shape with a radius R ₂ smaller than R ₁ , and both radii R ₁ ,
The centers of each circle based on R ₂ have different projected positions in FIG. 2 with respect to each other. The curvature of the rear guide rail 26 corresponds to the curvature of the glass 14 at the lowest position along the guide rail 26, so that when the glass 14 moves up and down, the window glass 14 directly facing the guide rail 26 is Since the ears move on an arc of radius R ₁ , as an auxiliary or alternative measure to the guidance of the window pane 14 by the carrier 18, guidance by a U-shaped rail that receives the vertical trailing edge of the window pane is also conceivable, in which case: A known pivot allowance, which will be described later with reference to FIGS. 3 and 4, is provided. Then, window glass 1
4. Since the carrier 18 moves within a range along the guide rail 26 without necessarily rotating on an arc of radius R ₁ corresponding to the curvature of the guide rail 26, the carrier 18 is perpendicular to the lifting direction A. It is not necessary to have flexibility around the swing axis included in the glass surface. A preferred embodiment of the rear carrier 18 is shown in FIG. 10 and will be described later.

The curved line of the front guide rail may be practically arbitrary, and in the illustrated example, it has the shape of a window glass 14. Each position of the glass 14 is specifically determined by the position of the carrier 18 at each lifting position and the guidance condition of the window glass between the door upper edge seal lips 22, and thus the corresponding position of the front carrier 16 is determined. Become.

Here, to further describe the overall structure of the window glass lifting device 10, both the carriers 16 and 18 have four guide rails 32 (disposed near the upper and lower ends of both guide rails 24 and 26) and eight They are simultaneously driven by one pulling wire 30 guided in a shape and running through a wire drum 34, which can be driven by a crank 36 or a drive mechanism not shown. Also, door 10
A small triangular window 38 is fixed in the front part.

Since the guide rails 24 and 26 have different curvatures, the angle between the two carriers 16 and 18, more precisely, the longitudinal direction 39 of the carrier 18 and the longitudinal direction of the carrier 16 projected onto the plane of FIG. The angle α with respect to the direction 40 changes, so that both carriers 16, 18 are aligned with the guide rails 24, 2.
6, the second furthest away from the intersection on the projection of each curved line
It is maximum at the lowest position in the figure, and minimum near the above-mentioned intersection (angle α' in the upper part of FIG. 2). window glass 14
The two areas facing the carriers 16 and 18 have a mutual orientation that is not affected by the vertical position. Therefore, the angle between the longitudinal direction 40 of the carrier 16 guided on the guide rail 24 and the window glass 14 in this vicinity changes on the plane of the second drawing. There, in order to prevent this angle change from making it difficult to slide the carrier 16 along the guide rail 24 or increasing the glass tension, the ninth
The carrier 16 shown in the figure has a rotation axis 42 parallel to the window glass surface and perpendicular to the lifting direction A, and has a carrier member 44 directly fixed to the window glass.
First joint 41 engaged with two carrier members 46
It is configured to be able to pivot freely. The carrier member 44 can be glued or otherwise connected to a window pane (not shown in FIG. 9), for example by screwing, as in the further embodiment according to FIGS. 11 and 14. Also good. This carrier member 44 has a substantially U-shaped horizontal cross section, and the U-shaped side piece 48 holds the other carrier member 46 .
8 and carrier member 46 (illustrated in dotted lines).
A pin-shaped rotation shaft 50 is passed through the pivot joint to form a pivot joint.

As shown in both cross sections of FIGS. 3 and 4, when the window glass lifting device 10 moves up and down, the carrier 18 of the window glass 14 is shown by a straight two-dot chain line for convenience.
The neighboring portion and the guide rail 24 are arranged in the sliding direction A.
The angle γ formed in the vertical projection onto the projection plane perpendicular to
also changes. The angle γ is defined, for example, as the angle between the parallel pieces 52, 54 and the glass 14 in the vicinity of a given position of the carrier.

When both carriers 16 and 18 are located near the - cross section in FIG. 2 and juxtaposed according to the projection shown in FIG. Thus, the angle .gamma. becomes zero degrees, and when the carriers 16, 18 are relocated and brought to the height of the - section in FIG. 2, the angle .gamma. ceases to be zero degrees. In order to bring about the above-mentioned angle change without generating torsional stress inside the window glass during the vertical movement, the front carrier 16 is provided with a rotation parallel to the longitudinal direction of the carrier (parallel to the longitudinal direction of the guide rail near the carrier). A second pivot joint 56 is provided having a dynamic axis 58. As shown in FIG. 9, the pivot joint 56 is comprised of a pair of split pivot shafts 60 spaced apart from each other in the direction of the axis 58, as shown in more detail in FIGS. 11-14. As would be expected, each pair of shaft members 62 facing each other are spaced apart with a gap 64 including the rotation axis,
In this gap 64, there is provided a side piece 54 of the guide rail 24 which is directed towards the other guide rail 26 of the U-shape.
is inserted. Therefore, both shaft members 62 are directly attached to the guide rail 24, and are each fitted into a cylindrical support hole 66 formed in the carrier member 46 in correspondence with the husband or the like. It is rotatable about the axis 58 together with the side piece 54 with respect to the member 46 . Note that the carrier member 46 includes:
In consideration of the above points, a wide longitudinal groove 68 is provided to communicate between the pair of two-part rotating shafts 60.

The tension wire 30 is connected to the carrier 16 by means of a wire nipple 70, which is in the x direction,
That is, it is fitted into a wire nipple storage chamber 72 having an opening corresponding to the direction of the other guide rail 26. By the way, as part of FIG. 9, beside the coordinate direction x, there is shown a coordinate direction z, which is directed upward parallel to the lifting direction A, and a coordinate direction y, which is perpendicular to z and x. .

Thus, due to the presence of the second pivot joint 56, the variation of the angle γ between the pane 14 and the guide rail 24 in the projections of FIGS. 3 and 4 will guide the corresponding rotation. It is permissible not to have the rail 24 run about its longitudinal axis.

During the raising and lowering movement, a corresponding fluctuation occurs in the rear guide rail 26, indicated by reference numeral δ in FIG.
10 and the window pane 14, this is allowed by a correspondingly pivotable configuration of the carrier 18 according to FIG. The rear carrier 18 has a (third) pivot joint 7 having a rotation axis 76 parallel to the carrier longitudinal direction.
4, which has the same construction as the second pivot joint 56 of the front carrier 16. In other words, the side piece 78 of the guide rail 26 having a Z-shaped cross section and oriented toward the front guide rail 24 also extends in the longitudinal direction of the carrier 18 connecting the pair of two-part rotating shafts 80 and the shafts 80. It is inserted into the groove 82. The window glass is raised and moved, and the carriers 16, 18 and the seal lip 22 on the upper edge of the door are removed accordingly.
When the distance between the front carrier 16 and
The third pivot joint 74 corresponding to the second pivot joint 56 is provided, and no other joint corresponding to the first pivot joint 41 is provided. Therefore, in the above state, the swinging moment around the swinging axis perpendicular to the lifting direction A of the window glass and included in the glass surface is transferred by the carrier 18 to the guide rail 2.
6 can be conveyed.

The connection of the carrier 18 to the pull wire 30 takes place in this case too by means of a wire nipple 84 in a wire nipple storage chamber 86 .

It should be noted that both carriers 16 and 18 of the double-strip type window glass lifting device shown in FIG. It may be driven by etc.

In addition, in order to block the swinging around the swinging axis that is perpendicular to the up-and-down direction of the window glass and included in the glass surface, if a method other than the above is used, the rear carrier is also configured in a double pivot type (rail The restriction on the curvature of the rear guide rail 26 (with the same orientation and curvature as the neighboring window panes) may be removed, and the window pane is then guided freely by both carriers 16, 18, but in any case the above-mentioned The window glass guiding system described above is used for arbitrarily curved window glass, and apart from this, it can also be used to guide the window glass in different orientations and/or curvatures, such as on both vertical edges of window glass that face each other in various lifting and lowering positions. This is an example of how to use both guide rails with different conditions. It is also possible to rotate it toward the seal lip inside the opening.

5 to 8 show a further embodiment of a double pivot carrier corresponding to the carrier 16 shown schematically in FIGS. 1 to 4, 9 and 10.

It consists of a support bolt 89 that is parallel to the glass surface and perpendicular to the rotation axis 42 and fixes the rotation axis 58,
This is fixed to a side piece 90 bent approximately parallel to the window glass 14 in the L-shaped cross section of the carrier member 46a, and is housed in a grooved support case 92 fixed to the member 88. The groove width of the case is set to a size sufficient to allow the rotation γ (FIG. 3) of the member 88 relative to the member 46a to change.

b has the same shape and configuration as the member 44a and the pivot joint 40a, respectively, but the carrier member 46b in this example is straight (unlike the L-shaped cross section of FIG. 5). It consists of a metal strip member.
The member 46b is fixed to the rotation shaft 50b by brazing or welding, for example, and is erected at right angles, and the opposite edge of the member 46b is provided with the above-mentioned pivoting shaft, which differs from the previous example in the following points. Support shaft 8 of joint 56b
9b is fixed. That is, when connecting the grooved case 92 of the joint to the member 88b having a U-shaped cross section, the case 92 is fixed to the side piece of the U-shaped cross section in the case of FIG. In the example, the carrier 16b is fixed in the middle of the U-shaped cross-section, and in this way the carrier 16b connects the window pane 14 and the guide rail 24 in a double pivoting manner.

Similarly, the carrier 16c according to FIG. 7 also couples the window glass 14 and the guide rail 24 in a double pivoting manner, and the first pivot joint 40c is the same as the pivot joint 40a according to FIGS. 5 and 6. and 40b. It should be noted here that FIGS. 5 to 8 are schematic diagrams, and the pivot joint shown in diagrammatic notation can also be realized in other ways. The second pivot joint 56c of the carrier 16c is schematically illustrated as a pivot joint substantially corresponding to the pivot joint 56 described with reference to FIGS.
A split support shaft 60 rotatably supported on the shaft grips the side piece 54 of the Z-shaped cross section of the guide rail 24.

The carrier 16d according to FIG.

A support shaft 50 whose both ends are rotatably supported by a support case 85 provided on the carrier member 44d to determine the horizontal rotation axis 42.
A second support shaft 89d (shown as an interrupted plane in FIG. 8) perpendicular to the axis 42 is provided at the longitudinally intermediate portion of d.
In this example as well, the second support shaft 89d, which is fixedly provided and defines the rotation axis 58, is fitted into the support case 92d of the carrier member 46d, which has a corresponding groove cut therein. The carrier member 46d is formed into a plate shape, and a member 93 having a U-shaped cross section is fixed to its longitudinal edge facing the case 92d.
This grips the side piece 54 of the guide rail 24 in a corresponding direction.

In FIG. 8, the dashed outline indicates the direction and position of the vehicle door on the opposite side of the vehicle body and the guide rail 24' placed inside the vehicle body, and the carrier 16d is also located on this side of the vehicle. In order to be able to install the carrier member 46d, it is necessary to rotate the carrier member 46d through a corresponding angle of about 180° about a rotation axis perpendicular to both the axes 42 and 58. At this point, the above member 46

11 to 14 are detailed views of a further embodiment of a dual pivot carrier, designated by the reference numeral 116 and corresponding to said carrier 16, of which said carrier Items corresponding in structure and function to 16 are given the same reference number as 1.
It is indicated by a number with 00 added.

00 (Fig. 12). As an auxiliary or alternative measure, the intermediate portion 144a may be attached to the glass 14 (patch reinforcement 202 in FIG. 13).

The side piece 144b in the U-shape holds another carrier member 146, and a support bolt 150 for determining the rotation axis 142 is connected to the carrier member 1.
46 and both side pieces 144b. The bolt 150 has a side piece 1 at its right end in FIG.
44b has a bolt head that abuts from the outside,
Further, at the end of the bolt located on the opposite side and extending through the side piece 144b on that side, an outer circumferential groove is provided at a corresponding portion, and a snap spring 204 is fitted thereinto to fix the bolt 150 in the axial direction. It is planned.

The carrier member 146 is connected to the second pivot joint 1
56, it is supported by the side piece 54 in the Z-shaped cross section of the guide rail 24 so as to be rotatable around the rotation axis 158 and slidable in the vertical direction A, and in the illustrated example, Instead of the pair of split support shafts 60 shown in FIG. 9, only one set of split support shafts 160, the details of which are shown in FIGS. 13 and 14, is provided.
Note that if the size of the window glass is large and the guiding conditions for the window glass are severe, using a pair of split support shafts spaced apart in the lifting direction as shown in FIGS. is always preferable because it is necessary to transmit the swing moment between the window glass 14 and the guide rail 26 about the swing axis parallel to the glass surface and perpendicular to the lifting direction. However, in the case of the front carrier described above, the existence of the two pivot joints 140 and 156 eliminates the need to receive the corresponding rocking moment, so in many cases, the split support shaft is It is sufficient to simply provide a length of 160 mm.

The support shaft 160 has a gap 164 defined along a plane including the axis 158, into which the side piece 54 of the guide rail 24 is fitted, and the flat dividing surface 210 of both shaft members 162 is inserted into the gap 164. Cross section side piece 54
is in contact with the side of the In addition, the above-mentioned both dividing surfaces 210
are each provided with a recess 212 in the axially intermediate region,
You can also add lubricant. The shaft member is provided with an outer periphery 214 formed by increasing the diameter at both ends in the axial direction, and further includes a carrier member 146.
are fitted together into a cylindrical support hole 166 provided in the. The support hole 166 is provided with the side piece 54.
The introduction groove 168 is open, and the groove 168 is
As is clear from FIG. 14, it passes through the support hole 166 and extends into the inside of the carrier member 146.
The inner groove end 215 is widened in the circumferential direction about the axis 158 to allow suitable pivoting.

The support hole 166 opens at the upper end surface of the carrier member 146 in FIG. Also, the hole 1
Inner circumferential grooves 220 formed by increasing the hole diameter are provided at both axial ends of the shaft members 162.
The outer circumferential collar 214 of the shaft member 162 is fitted thereinto, and the shaft member 162 is thus fixed in the axial direction inside the hole 168.

The purpose is to allow the carrier 116 to travel along the guide rail 24 easily and without noise.
Alternatively, in order to ensure reliable production even when the manufacturing accuracy of the guide rails is not constant, a rubber cord 222 is attached to the outer periphery of one of the pair of shaft members 162.
58, and therefore, the shaft member 162
is pressed against the side piece 54 without any play.
The rubber cord is disposed in a recess 224 extending in the inner circumferential wall of the support hole 166 with appropriate parallelism to the axis 158.

(Effects of the Invention) As is clear from the above explanation, according to the present invention, the inclination angle between the guide rail and the window glass near the carrier of the window glass lifting device is constant or varies as the window glass moves up and down. For example, if the radius of curvature of the guide rail is different from the radius of curvature of the window glass guide, the inclination angle will inevitably vary, but it has the great effect of allowing such variation. . Furthermore, for carriers, there is no problem with practical restoring force, and extremely light running can be expected, and in addition, the rigidity of the parts that is often desired for rotation around an axis different from the rotation axis can be expected. . In addition to the above, it has various other effects, such as being able to manufacture and install it at a very small cost.
