Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a sashless door for an automobile, and more particularly to a window regulator for a sashless door suitable for a flush-surfaced body.

1. Prior Art As is well known, 1. In order to improve the aerodynamic characteristics of passenger cars and respond to changes in user preferences, flush-surfaced bodies are being adopted in which the outer surface of the vehicle has as few irregularities as possible. However, in a car with a door without a door, it is difficult to create a flush surface because there is no door to guide the window panel. In other words, in a flush-surfaced body, the outer surface of the window panel in the closed state must be located on an extension of the door outer panel or vehicle body panel, but in the structure of a typical window regulator, Since the window panel is opened and closed inside the door, if the lower end of the closed window panel is placed close to the general surface of the door outer panel, the window panel cannot be stored inside the door.

For this reason, Japanese Patent Application Laid-Open No. 56-81785 has proposed a window regulator for a sashless door that can control the attitude of a window panel also in the thickness direction of the door when opening and closing. That is, the window regulator disclosed in the publication has a pair of curved guide rails that guide the lower end of the window panel, and a pair of curved guide rails that guide the lower portions of the window panel on both sides in the longitudinal direction of the vehicle body. These guide rails gradually control the posture of the window panel during lifting and lowering operations, achieving both a flush surface for the stubless door and the ability to store the window panel.

However, since this window regulator has a structure in which four independent guide rails are individually fixed to the door inner panel, assembly and adjustment of the automobile door is extremely troublesome, which poses a practical problem. In addition, since the window panel of the window regulator is controlled in posture by drawing a movement trajectory as shown in Figure 5 of the above-mentioned publication, there is no particular problem in the closed state or fully open state, but the window panel When the panel is in a half-opened state, the upper end of the window panel protrudes outward beyond the outside line of the vehicle body. As a result, when the window panel is in a half-open state, there are problems such as the generation of wind noise due to the protrusion of the upper end of the window panel and the entrapment of pedestrians by the protruding upper end.

1. OBJECTS OF THE INVENTION 1. An object of the present invention is to solve the problems of the window regulator of conventional satsure-less doors as described above, and to make assembly and adjustment of the door panel easy, so that even when the window panel is half open, a part of the window panel can be removed from the vehicle body. To provide a window regulator for a satsuru door that does not protrude outside the outside line of the door and can ensure stable lifting and lowering of the window panel.

Structure of the Invention - In order to achieve this object, the present invention supports an elevating member along a guide member fixed to a door inner panel, and configures a four-bar linkage mechanism between it and a supporting member that holds a window panel. A support member is attached to the elevating member with at least two sets of links, a block is fixed to the support shaft with at least one link support shaft for the elevating member and the support member being coaxial, and the block is attached to the corresponding elevating member or the support member. A position regulating member that prevents movement of the device is fixed, and a biasing spring interposed between the lifting member and the lifting member presses the supporting member in one direction, and when the supporting member approaches the upper limit, the device fixing portion It is proposed that the support member be moved toward the outside of the door against the force of the biasing spring by means of a stopper provided in the support member.

One example- Embodiments of the invention will now be described in detail with reference to the drawings.

1 to 6 show a first embodiment of the present invention, and this window regulator has a pair of idle rails (guiding members) IA and IB that are installed inside a door in a state that is adjacent to each other in the longitudinal direction of the vehicle body. have. In other words, these guide rails IA and IB are curved in a cross section in the door thickness direction shown in FIG. 3, and are straight in the plane shown in FIG. The guide rails IA and IB are located along the waist line L formed by the waist weather strip 2 in the plane of FIG.
The relationship is perpendicular to . And these guide rails IA.

The lower part of 1B is integrated by a connecting plate 3, and by adjusting the position of the connecting plate 3 fixed to the door inner panel 4, the angle of both guide rails IA and IB with respect to the waistline L can be adjusted.

Each guide rail IA, IB having a "U"-shaped cross section has opposing guide grooves la, lb as shown in FIG.

A pair of elevating tables (elevating members) 7A having protrusions 7a and 7b that slidably engage with 1b.

7B is a holder that can be moved up and down along each guide rail IA, IB. That is, one of these lifting platforms 7A and 7B is connected to both ends of an actuation wire 10 whose middle part is hooked to a pulley 8.9 attached to the upper and lower ends of the corresponding guide rails IA and IB. It can be raised and lowered by a drive drum 12 of a geared motor 11 that drives the. Each of the lifting platforms 7A and 7B is provided with a pair of mounting walls 7c and 7d that protrude toward the outside of the vehicle body from the guide rails IA and IB, and two sets of links are provided at the upper and lower ends of these mounting walls 7c and 7d. The base of 13.14 is supported by a support shaft 15.16. The tips of the links 13 and 14 are engaged with the corresponding support plates 17A and 17B through support shafts 18 and 19 on the back surfaces of the support plates (support members) 17A and 17B, respectively. As shown enlarged in FIG. 4, each pair of links 13 and 14 constitutes a four-link mechanism in combination with the lifting platforms 7A and 7B and the support plates 17A and 17B. By making the lengths of 14 different, the elevating platform 7A.

The inclination of support plates 17A and 17B with respect to support plate 7B and the amount of separation between them can be changed.

1 actuation link 2 is provided on the back surface of each of the support plates 17A and 17B.
0 bases are rotatably supported by support shafts 19,
The bins 21 at the tips 20a of these operating links 20 are the respective lifting platforms 7A.

It is guided to the moving part along the sliding groove 23 formed in the notch 22 of 7B. Further, the other end of a biasing spring 24 whose one end is hooked to the back surface of the corresponding support plates 17A, 17B is hooked to the intermediate portion of the operating link 20, and the biasing spring 24 causes the operating link 20 to move to the fourth position. It is biased counterclockwise in the figure. Therefore, the force of the biasing spring 24 biases the operating link 20 in the counterclockwise direction in FIG.
Since the links 13° and 14 are rotated clockwise around the support shafts 15 and 16, the support plate ! 7A, 1
7B is the lifting platform 7A as shown in Fig. 6.

It is kept close to 7B. On the other hand, stoppers 25A and 25B are fixed to the upper ends of each of the guide rails LA and IB, the tips of which can enter into the notches 22 when the respective lifting platforms 7A and 7B move to their highest positions.

These stoppers 25A and 25B are connected to each lifting platform 7A,
When 7B moves to the highest position shown in FIG. 4, it engages with the tip 20a of the actuating link 20 and presses it downward. Therefore, in the latter half of the upward stroke of the lifting platforms 7A and 7B, the stoppers 25A and 25B press the tip 20a of the operating link 20 downward, but the bottle 21 of the tip 20a slides as described above. Since it is guided by the groove 23, the clockwise rotation of the operating link 20 causes the links 13 and 14 to rotate counterclockwise, and the lifting platform 7A.

The inclination angle of the support plates 17A and I7B with respect to 7B changes, and the support plates 17A and 17B are the lifting platform 7A.

Move away from 7B. In addition, since the window panel 28 at the lower end 27a of the window panel 27 is fixed between the support plates 17A and 178 via the spacer 26, the window panel The lower end portion 27a of the window panel 27 rapidly moves toward the door outer panel 29, and the window panel 27 is positioned on an extension of the door outer panel 29.

The window regulator of the first embodiment has a structure for stabilizing the behavior of the window panel 27 due to the collapse of the links 13, 14 during the opening/closing operation of the window panel 27. FIG. 5 shows the same structure represented by a link 14, in which the base and tip of the link 14 are attached to the lifting platform 7B and the support plate 17B by coaxial support shafts 16 and 19. A cylindrical rotation block 30.31 is fixed at the middle of the support shaft 16.19 so as not to move in the longitudinal direction of the support shaft 16.19. On the front surface of the lifting platform 7B and the back surface of the support plate 17B corresponding to each rotating block 30.31, there is a pair of "coats" having side portions 32a and 33a with an interval equal to the length dimension of the rotating block 30.31. ""-shaped position regulating members 32, 33 are fixed respectively, and a rotating block 30, 31 is received between these side parts 32a, 33B to prevent the support shaft 15, 18 from moving in the longitudinal direction. . Of course, in the first embodiment, behavior stabilization means consisting of rotation blocks 30, 31 and position regulating members 32 and 33 are also provided for the support shafts ts and ia of the link 13.

Since the window regulator according to the first embodiment has the above-described structure, in the vehicle body assembly process, both guide rails IA are aligned with the waist line L of the door panel.
, adjust the IB so that it is at a right angle, and then attach the door inner panel 4.
It is sufficient to fix the guide rails IA and IB to the guide rails IA and IB. Further, the window regulator of the first embodiment has a geared motor 1.
1, the window panel 27 can be opened and closed by remote control by driving the operating wire 10. When the window panel 27 is in a completely open state, each member assumes the position indicated by the imaginary line in FIG.
is in a state closer to the elevator platform 7A, 7B side, that is, the door inner panel 4, due to the force of the biasing spring 24. Therefore, as the elevator platforms 7A and 7B rise, the window panel 27
The lower end 27a and upper end of the window panel 27 rise along the interlocking trajectories α and β shown in FIG. Therefore, the upward movement of the window panel 27 is carried out smoothly (as shown in Fig. 6), and since the movement locus β of the upper end of the window panel 27 is inside the outside line of the vehicle body, the window panel 27 is stopped in a half-open state. Also, it is possible to prevent wind noise from occurring while the vehicle is running, and the upper end of the window panel 27 protruding outside the outside line of the vehicle body from causing a sense of discomfort or causing pedestrians to get caught in the vehicle.

The lifting tables 7A and 7B are further raised, and the lifting tables 7A and 7
When B is the road eye section and the window panel 27 is in the B111 button state, the elevator platform 7A is activated.

7B rises, the upper stoppers 25A and 25B of the guide rails IA and IB enter into the notch 22, and the stoppers 25A and 25B are attached to the tip 20a of the operating link 20.
However, since the tip 20a is guided by the sliding groove 23, the operating link 20 engages with the pin 2 of the tip 20a.
1 as a fulcrum and rotates clockwise against the biasing spring 24. For this reason, links 13 and 14 are used for lifting platforms 7A and 7B.
The support plates 17A and 17B supported by the support plates 17A and 17B are rotated and moved to the state shown in FIG. In other words, window panel 2
7 approaches the closed position, the support plates 17A and 17B move toward the door outer panel 29 and rotate, causing the lower end 27a of the window panel 27 to close to the door outer panel 2.
The window panel 27 is rapidly moved in nine directions, and the lower end 27a of the window panel 27 is brought into close contact with the waist weather strip 2. Therefore, the window panel 27 in the closed state is pushed out to the outside of the vehicle body by pushing out the lower end 27a of the window panel 27.
The surface of the door panel 29 can be located on an extension of the door outer panel 29 to obtain a flush-surfaced body. In this case, since the locus of motion of the upper end of the window panel 27 hardly changes, the upper end and side portions of the window panel 27 are easily sealed with a conventional weather strip installed at the opening of the vehicle body.

Furthermore, when the window panel 27 is completely closed, the amount of movement of the lower end 27a of the window panel 27 toward the door outer panel 29 is determined by the guide rail I as described above.
A.

Since the direction of the IB is perpendicular to the waist line L, even if the waist line L is inclined from the horizontal line, when viewed from the end of the waist weather strip 2 in the longitudinal direction of the vehicle body, they are completely equal. Therefore, in the structure of the first embodiment, the degree of freedom in shaping is increased by tilting the waist line L with respect to the horizontal line or making the waist line L curved.

When opening the window panel 27 from the closed state 5B, when the lifting platforms 7A and 7B are slightly lowered, the stoppers 25A and 25B operate at the tips 20a of the links 20.
The force of the biasing spring 24 causes the support plate 17A to move away from the
, 17B return to the state shown in FIG. 6, and the lower end 27a of the window panel 27 is stored inside the door along the movement trajectory α intermediate between the door outer panel 29 and the door inner panel 4.

Furthermore, in the structure of the first embodiment, during the opening/closing operation of the window panel 27 described above, no unreasonable external force is directly applied to the links 13.14, so the behavior of the window panel 27 is affected by the deformation of the links 13.14. In other words, the supporting shafts 15, 16 of the links 13, 14 are prevented from moving in the longitudinal direction by the position regulating members 32 and 33, so that they cannot be forcibly removed from the window panel 27. When a force is applied to the link 13.14, this external force is transferred via the rotating block 30.31 to the regulating member 32.3.
Can be accepted by 3. Conversely, due to external force, link 1
Even if 3.14 tries to tilt in a direction perpendicular to the paper plane of FIG. 4, this is prevented by the position regulating member 32.33, so the behavior of link 13.14 and support plates 17A and 17B is kept stable. be able to.

FIGS. 7 to 11 show a second embodiment of the present invention, and the window regulator of this embodiment has a wide guide plate (guide member) 101 that is incorporated into the inside of a sashless door. That is, these guide plates 101 are curved in the cross section in the door thickness direction shown in FIG. 8, and are formed in a straight line in the plane shown in FIG. Both side surfaces 101c and 101d of the plate 101 and the central guide surface 101e are as in the first embodiment,
In the plane of Fig. 7, the waist weather strip 1
The relationship is perpendicular to the waist line L formed by 02. Both side surfaces 101c, IQld, and central guide surface 101e of the guide plate 101 fixed to the door inner panel 104 guide movable pulleys 134, 135, 138 that can move along these. The lift plate 107 to which 138 is attached is slightly floating from the guide plate LQ1, and the guide plate 10
It is raised and lowered by an actuating wire 110 whose middle part is hooked to pulleys 10B and 109 at the upper and lower ends of 1. That is, both ends of the actuating wire 110 are connected to the elevating plate 107, and the actuating wire 110 can be raised and lowered by a drive drum 112 of a geared motor 111 that drives the actuating wire 110. Further, the elevating plate (elevating member) 107 has a pair of mounting portions 10 bent at right angles toward the door inner panel 104 at both sides of the guide plate 101 . c and 107d, and on the upper and lower outer surfaces of these mounting portions 107c and 107d, the bases of one pair of links +13A and 114A are connected to support shafts 115A and 118.
I support it with A. Link! The tips of +3A and 114A are respectively engaged with the corresponding back surface portion of the support plate 117 by support shafts 118A and 119A on the back surface portion of the support plate (support member) 117 which also serves as a window panel. 6 pairs of links 113A
, 114A are the lifting plates 1 as shown in an enlarged view in FIG.
07 and the support plate 117 constitute a 4I'i link mechanism, and the link 112A and the link 114
By varying the length of A, the inclination of the support plate 117 with respect to the elevating plate 107 and the amount of separation between the two can be changed.

A pair of actuation links 12 are provided on the back surface of each support plate 117.
The bases of OA and 120B are rotatably supported by a support shaft 119A, and these operating links 12OA and 120
The tip 120a of B is projected onto the guide plate 101 through the window 137 of the elevating plate 107 shown in FIG. Print! @ Let the movable note guide along the groove 123A. Further, the operating link 12
A biasing spring 124A whose one end is hooked to the back surface of the support plate 117 and the other end of the biasing spring 124A is hooked to the intermediate portion of the OA, 120B.
20B is biased counterclockwise in FIG. Therefore, due to the force of the biasing spring 124A, the operating link 12OA,
120B is biased counterclockwise in FIG. 9, the links 113A and 114A are rotated clockwise around the support shafts 115A and 118A, and therefore, in normal cases, the support plate 117 is biased in the imaginary direction in FIG. It is maintained at a position close to the elevator plate 107 as shown in the line. On the other hand, on the upper surface of each of the guide plates 101, when each y-no-descend plate 107 moves to the highest position, the tip portions 12 of the operating links 12OA and 120B are provided.
A stopper 1250.1250 is fixed that can be engaged with Oa. These stoppers 125C, 1250 engage with the tips 120a of the operating links 120^, 120B and press them downward when each elevating plate 107 moves to the highest position shown in FIG. Therefore, the lifting plate 1
0? In the latter half of the upward stroke of the stopper 125C, 1
250, the tip part 1 of the actuating link 12OA, 120B
20a is pressed downward, but since the pin 121A of this tip 120a is guided by the sliding groove 123A as described above, the links 113A and 114A are rotated clockwise by the operating links 12OA and 120B. It rotates counterclockwise, the angle of inclination of the support plate 117 with respect to the elevating plate 107 changes, and the supporting plate 117 separates from the elevating plate 107. Furthermore, since the lower end 127a of the window panel 127 is fixed to the support plate 117, the lower end 127a of the window panel 127 rapidly moves toward the door outer panel 129 as the support plate 117 moves toward the outside of the vehicle body. , the window panel 127 is positioned on an extension of the door outer panel 129.

The window regulator of the second embodiment has a structure for stabilizing the behavior of the window panel 127 due to the collapse of the links 113A and 114A during the opening/closing operation of the window panel 127. FIG. 11 shows link 113A,
The same structure is represented by the tip of link 114A, and the tips of links 113A and 114A are coaxial with support shaft 11.
8A and 119A are attached to the support plate 117, and in the middle part of these support shafts 118A and 119A, a cylindrical rotation block +3OA and 131A are attached to the support shaft 118A.
, 119A are fixed so as not to move in the length direction. On the back surface of the support plate 117 corresponding to each rotation block 130A, 131A, there is a pair of "co" having side portions 132a, +33a with an interval equal to the length dimension of the one rotation blocks 130A, 131A.
The °-shaped position regulating members 132A and 133A are fixed respectively, and the supporting shaft 1 is
18A and 1i9A are prevented from moving in the length direction.

Although the tips of the links 113A and 114A in this embodiment are stabilized by such means, and this configuration provides a sufficient window panel stabilization structure, the bases of the links 113A and 114A may be stabilized as necessary. You can also. In this case, the mounting portion 107c of the elevating plate 107
, 107d may be folded toward the door outer panel 129 side, and position regulating members similar to the position regulating members 132A and 133A may be placed on the surface of the elevating plate 107.

Since the window regulator according to the second embodiment has the above-described structure, in the car body assembly process, the guide plate 101 is adjusted to be perpendicular to the waist line L of the door panel, and the door inner panel The guide plate 101 may be fixed to 104. Further, the window regulator of the second embodiment operates by driving the operating wire 110 by the geared motor 111, thereby controlling the window panel 127.
can be opened and closed by remote control. When the window panel 127 is in a completely open state, each member assumes the position indicated by the imaginary line in FIG.
Due to the force of 4A, the elevating plate 107 side, that is, the door inner panel 1
It is close to 04. Therefore, the elevating plate 10? As the lower end 127 of the window panel 127 rises, the lower end 127 of the window panel 127
a and the upper end of the window panel 127 rise along the motion trajectories α and β in FIG.
Since the movement locus α of 7a is approximately midway between the door outer panel 129 and the door inner panel 104, its upward movement is performed smoothly. Since the motion trajectory β of the upper end of the window panel 127 is inside the outside line of the vehicle body,
Even if the window panel 127 is stopped in a half-open state, it is possible to prevent wind noise from occurring during driving, a sense of discomfort caused by the upper end of the window panel 127 protruding outside the outside line of the vehicle body, and pedestrians being trapped.

When the lift plate 107 is further raised and the window panel 127 is in a substantially closed state, the lift plate 107 is raised and the stopper 1 on the upper part of the guide plate 101 is lifted.
25C:, 12511 is the operating link t20A, 1208
(7) Engages with the tip portion 120a, but the tip portion 120a
a is guided by the sliding groove 123A, so the operating links 120A and 120B are connected to the bottle 121A of the tip 120a.
It rotates clockwise against the biasing spring 124A using the fulcrum as a fulcrum. Therefore, the lift plate 1 is connected to the links 113A and 114A.
07 is rotated and moved to the state shown in FIG. In other words, the window panel 127
When the window panel 127 approaches the closed position, the support plate 117 moves toward the door outer panel 129 and rotates, causing the lower end 127a of the window panel 127 to close to the door outer panel 129.
The waist weather strip 1
02, the lower end 127a of the window panel 127 is brought into close contact with the window panel 127. Therefore, the lower end 12 of the window panel 127
By extruding 7a to the outside of the vehicle body, the surface of the window panel 127 in the closed state can be positioned on an extension of the door outer panel 129, and a flush surfaced body can be obtained. In this case, since the locus of movement of the upper end of the window panel 127 hardly changes, the upper end and side portions of the window panel 127 are easily sealed with a conventional weather strip installed at the opening of the vehicle body.

Furthermore, when the window panel 127 is completely closed, the amount of movement of the lower end 127a of the window panel 127 in the direction of the door outer panel 129 is determined by the guide plate 1 as described above.
Since the direction of 01 is perpendicular to the waist line L, even if the waist line L is tilted from the horizontal line, when viewed from the end of the waist weather strip 102 in the longitudinal direction of the vehicle body, they are exactly the same.

Therefore, in the structure of the second embodiment, the degree of freedom in shaping is increased by tilting the waist line L with respect to the horizontal line or by making the waist line L curved.

When opening the window panel 127 from the closed state, when the lifting plate 107 is lowered slightly, the stopper 1
25G, 1250 is working link 12OA, 120817
) When the note leaves the tip 120a, the support plate 117 returns to the state shown in FIG. 6 due to the force of the biasing spring 124A, and the lower end 127a of the window panel 127 moves midway between the door outer panel 129 and the door inner panel +04. It will be stored inside the door along the trajectory α.

Further, in the structure of the second embodiment, during the opening/closing operation of the window panel 127 described above, no excessive external force is applied directly to the links 113A and 114A.
, 114A will not cause the behavior of the window panel 127 to become unstable. That is, link 113A, 1
The support shafts 118A and +19A of 14A are prevented from moving in the longitudinal direction by the position regulating members 132A and 133A, so if an unreasonable force is applied from the window panel 127 to the links 113A and 114A, this External force is received by position regulating members 132A, 133A via rotation blocks 130A, 131A. In other words, even if the links 113A, 114A tend to tilt in a direction perpendicular to the plane of FIG. can be kept in a stable state.

In each of the above embodiments, the guide rails IA, IB and the guide plate 101, which are the guide members, are arranged at the waist line L.
In the present invention, these guide rails LA, IB and the guide plate 1
01 may be oriented at right angles to the horizontal direction.

Effects of the Invention - As is clear from the above description, in the window regulator of the present invention, the lower end of the window panel is rapidly moved toward the outside of the vehicle body immediately before the window panel is closed, so that the window regulator has a flush surface. Since the upper end of the window panel is always located within the outside line of the vehicle body when the window panel is half open, there is no need to worry about the generation of wind noise or the possibility of pedestrians getting caught in the vehicle. It can have no structure. Furthermore, in the window regulator of the present invention, one assembly and adjustment can be performed simply by assembling the guide member to the door panel, so that a structure that facilitates one assembly and adjustment can be obtained. Furthermore, in the present invention, the block is fixed to the link support shaft of at least one of the elevating member and the supporting member, and the movement of the block is prevented by the position regulating member that is fixed to the elevating member or the supporting member, so that no excessive external force is applied to the link. It is possible to obtain a structure in which the ascending and descending properties of the window panel are not deteriorated due to this effect.
