DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shoe structure in a wind regulator device for a vehicle having no sash hardware for supporting an upper end of a window glass, such as a passenger car, particularly a hard-top vehicle.

[0002]

2. Description of the Related Art Conventionally, a wire-type window glass regulator has been used to drive a window glass that moves up and down from a door body. FIGS. 14 and 15 show a window regulator device that has been widely known from the past (for example, see Japanese Utility Model Laid-Open No. 2-129585). In FIGS. 14 and 15, 25 is a window glass, 50
Is a guide rail arranged substantially vertically in the door main body. The guide rail 50 is fixed to the door main body via upper brackets 51 and lower brackets 51 at upper and lower ends 51, respectively. Reference numerals 30a and 30b denote upper shoes and lower shoes slidably mounted on the guide rails 50, respectively. Reference numeral 14 denotes a carrier plate that is coupled to the upper shoes and lower shoes and that can move up and down along the guide rails 50.

The upper shoe 30a and the lower shoe 30b are
As shown in FIG. 14, the carrier plates 14 are vertically arranged. The carrier plate 14 has a connecting portion 27 for attaching a window glass 25 at two places. Glass
Each of the 25 has a bolt insertion hole, and the window glass 25 is fixed to the carrier plate 14 by a bolt. Further, in FIG. 14, reference numeral 15 denotes pulleys provided on the upper and lower brackets and the lower bracket, respectively.
A wire cable 13 is wound around these pulleys 15. The wire cable 13 is placed in the proper position 20 on the carrier plate 14.
When the carrier plate 14 is driven via the wire cable 13 by the operation of the drive mechanism 18, the window glass 25 moves up and down.

[0004] In a shoe 30a in a guide rail 50 having a C-shaped cross section provided with a streak-shaped opening in the peripheral wall, a base member 32 serving as a base portion (connection portion) of the carrier plate 14 and a depth side thereof are provided. It is composed of a sliding member 36 arranged in an overlapping manner, an elastic body 34 disposed in a concave portion on both sides between them, and a sliding member 36b pressed against the inner surface 50c of both side walls of the guide rail 50 by the elastic body 34. .

[0005]

In the structure of the shoe in this conventional window regulator device, the inner surfaces 50c on both sides of the guide rail 50 in FIG.
Since the sliding member 36b is pressed by the elastic body 34 and the sliding member 36 is pressed against the bottom surface 50b of the guide rail 50, when the shoe 30a moves up and down in the guide rail 50, It has the characteristic that it can move up and down smoothly without rattling in the left and right or in the depth direction. However, as is apparent from FIG. 1, the rail is generally formed so as to bulge outward, and the bottom surface 50b of the guide rail 50 and the inner surface 50a of the inner wall of the guide rail 50 are formed.
Is not completely uniform at any point in the longitudinal direction. Then, from the viewpoint of the design, it is necessary to determine the dimension of the shroud 30a in the depth direction with respect to the smallest inner dimension of the dimension W therebetween. Therefore, at a place where the depth dimension W is large in the guide rail 50, the shoe 30a has a problem that rattling occurs in the depth direction and rattling occurs.
In addition, when the window glass 25 in FIG. 1 receives the suction force due to the wind in the direction of arrow 19a while the car is running at high speed,
The reaction force must be received by the lower shoe 30b of the shoe.
When there is a play on b, the shoe 30b sinks and the upper part of the window glass 26
Opening outward (in the direction of 19a) causes wind noise and rainwater, causing problems.

The structure of the shoe in the wind regulator device of the present application is provided to solve the above-mentioned problems of the prior art. The purpose of the present application is that even if the rail is curved in a state in which it bulges outward, the shoe smoothly moves up and down along the curve, and similarly, the glass curved outwardly along a fixed locus. It is an object of the present invention to provide a window regulator device that can be driven up and down. Another purpose is that even if there are variations in the inner dimensions of the rail in the depth direction, the shoe always expands and contracts in accordance with the inner dimensions of the rail, so that the rails always have a larger diameter. An object of the present invention is to provide a structure of a shoe in a wind regulator device which is in contact with an inner surface without a gap and eliminates backlash in a depth direction. Another purpose is that, when the vehicle travels at high speed with the sashless type window closed, even when the upper part of the glass 25 receives a large suction power toward the outside, even if the suction power is small or large. It is an object of the present invention to provide a shoe structure in a wind regulator device in which expansion and contraction is performed in accordance with the expansion and the deflection of the glass toward the outside is restricted to a very small extent. Another object of the present invention is to provide a shoe structure in a window regulator device in which the tightening force between the glass and the shoe can be adjusted even from the bottom (back side) of the guide rail.
Other objects and advantages will be more readily apparent from the drawings and the following description associated therewith.

[0007]

The structure of the shoe in the window regulator device according to the present invention includes a guide rail having a C-shaped cross section provided with a streak-shaped opening in the peripheral wall and an inner wall surface of the sliding space of the guide rail. The shoe includes a shoe slidably supported and driven in a vertical direction by a drive mechanism, and a window glass connected to the shoe so as to move up and down in conjunction with up and down movement of the shoe.

Reference numeral 20 denotes a portion where a part of the wire 16 is fixed to the carrier plate 14. Reference numeral 21 denotes a stopper position for limiting the ascending position and the descending position of the carrier plate 14.

Next, as shown in FIG. 1, the window glass 25 is normally curved so that the outside of the room is bulged, and is fixed to the frames 7, 8 as shown in FIGS. It moves up and down while the left side in the figure is supported by the delta sash 12 that has been set. Depending on the type of vehicle, the upper end of the delta sash generally extends upward, and holds the upper end 26 of the glass in a rising state. However, in a sashless type such as a hard-top car, the upper end 26 of the glass is connected to the receiving portion of the vehicle body. It is only in contact with 24, it is in a free state toward the outside, and if a strong suction force is applied, its upper end is outside the room 19
Receives a large suction power to a. The window glass 25 has a connecting portion 27 at the bottom. The structure of the connection is shown in detail in FIGS.

Next, the guide rail 50 will be described. As shown in FIGS. 4 and 5, the guide rail 50 has a U-shaped free end directed inward as shown in FIGS. 4 and 5, and is generally called a C-shaped steel. Therefore, as shown in FIGS. 2 and 3, a streak-like opening 54 is formed between the bent portions 53. The guide rails 50 are arranged in the vertical direction of the door panel so as to correspond to the vertical movement locus of the window glass 25. Next, reference numeral 30 denotes a shoe for vertically sliding the sliding space 52 of the guide rail 50. The surface of the guide rail 50 which contacts the inner wall surface is formed of a slippery material, for example, a plastic material (eg, polyacetal, nylon, etc.). Have been. 4 and 5, the cover members 31a, 31b, 31
Each of c is plastically formed of an integral material, and a base member 32 of the metal connecting rod 40 is accommodated in an inner space. The lower member of the base member 32 has a cushioning property, for example, shows an elastic body 34 made of synthetic rubber or the like, and further below, that is, a sliding member 36 in contact with the bottom surface 50b of the guide rail 50,
4, 5, 6, 7, and 8,
It is made of a slippery member (for example, polyacetal or nylon). In such a configuration, the surfaces sliding on the inner surfaces of the guide rails 50 are each formed of a slippery material such as plastic, so that they move up and down very smoothly. Next, the base member 32 at the base of the connecting rod 40 is
32b and the seat plate member 32a are integrally formed of a metal material. Reference numeral 41 denotes a pressing member for pressing the glass 25, which has a female screw therein and is usually called a nut. Therefore, in assembling, the seat plate member 32a connected to the connecting rod 40 is pushed (or plastically integrally formed) into the inside of the outer cover member 31 of the shoe 30, and then the elastic body 34 and the sliding member 36 are respectively attached to the shoe 30 in FIG. Assemble as shown in 5. in this case,
An annular bulging portion 37 that bulges on the surface of the sliding member 36 is brought into contact with an annular contact surface 35 provided on the back surface of the elastic body 34. These are inserted from the end of the guide rail 50 to the inside. In this case, when there are a plurality of shoes 30 in the upper part and the lower part, these outer cover members 31 are connected to each other in advance by a connecting member 39 as shown in FIG. The connecting member 39
The material is a member 39 (for example, polyacetal, nylon, or the like) having flexibility as long as the interval between the shoes can be kept constant, and is connected to the jacket member 31a by an integral plastic molding. The shape of the bulging portion 37 provided on the surface of the sliding member 36 is not limited to the annular shape of FIG. 7A, but also to the shape of an independent columnar bulging portion 37 as shown in FIGS. The bulge may be of any shape, such as the bulge 37 having the shape of a circle.

Next, the glass 25 having a plurality of holes 28 is attached to the shoes 30, 30 while penetrating the heads of the connecting rods 40, 40, respectively. In that case, washers 45 and 46 are overlaid on both surfaces of the glass 25. This washer is preferably larger in size than the inner diameter of the hole 28, and the outer washer 45 is formed of a hard sheet metal, and the inner washer 46 is formed of a soft material capable of soft touch such as resin. In this case, as shown in FIG. 3, the carrier plate extended between the left and right wires 16, 16.
4, the female screw of the nut 41 and the male screw of the connecting rod 40 are screwed together as shown in FIG. Then, the glass 25 and the shoe 30 are integrated via the rod-shaped connecting rod 40. Note that the width of the seat plate member 32a is set so that the tensile force of the seat plate member 32a in the direction of the window glass can be covered by the inner opening edge of the bent portion 53 of the guide rail as apparent from FIG. The width of the opening 54 is larger than the width of the opening 54.

Next, when there are large and small variations in the dimension W between the inner surface 50a and the bottom surface 50b of the guide rail 50 in the longitudinal direction, and when a pressing force is applied to the shoe 30, respectively. The operation of the shoe 30 will be described with reference to FIGS. FIG. 8A shows a case where the dimension W is an average dimension, and a swelling portion 37 is formed in a state where a gap G is formed between both opposing surfaces 34a and 36a of the elastic body 34 and the sliding member 36.
Is lightly in contact with the contact surface 35. In that state
The repulsive force of the elastic body is in a relatively small range in the section indicated by reference numerals (O) to (A) in FIG. Next, FIG. 8C shows a state of the shoe 30 when the shoe 30 passes through a portion of the guide rail 50 where the dimension W is slightly smaller due to a manufacturing error. The sliding member 36 is pressed against the elastic body 34 by the bottom surface 50b, and the opposing surfaces 34a, 36a of the sliding member 36
9 shows a state in which it is deeply sunk into the elastic body 34, that is, a state in a section (C) in FIG.
The resilience of the elastic body is slightly larger than that of the section (A). Next, FIG. 8B shows that the window glass 25 receives the suction force in the direction of the arrow 19a in the state of FIGS. 1 and 4, and a pressing force in the direction of the arrow 19c is generated in the lower shoe 30b of the upper and lower two shoes. This shows the state of the shoe when it is done. In this state, the connecting rod 40 receives a pressing force in the direction of arrow 19c, and causes the elastic body 34 to slide on the sliding member 36.
Press toward. Then, the elastic body 34 and the opposing surfaces 34a and 36a of the sliding member 36 come into contact with each other, and the repulsive force of the elastic body rapidly increases in the range of the symbol (B) in FIG. As described above, the elastic body 34 and the sliding member 36 in the shoe 30 function as shown in FIGS. 8A and 8C to fulfill the roles of expansion and contraction, respectively.
Shoe 30 and guide rail
A gap is formed between the 50 and the inner surface to prevent rattling and noise. Also, the pressure in the direction of arrow 19a in FIG. 4 is as shown in FIG. 8B, and a corresponding repulsive force is exerted so that the upper edge 26 of the window glass 25 opens greatly toward the outside of the room. There is a function to prevent.

Next, a description will be given of a shoe 30e located on the lower side of FIG. 10 showing a configuration example in which the positional relationship between the elastic body 34 and the seat plate member 32a is reversed in the shoe 30 shown in FIG. As shown, the seat plate member 32ae directly abuts the sliding member 36e. A rough surface or a pair of uneven surfaces may be provided so as to mesh with each other so as not to slide on the contact surfaces of both. Thus, even if the force in the direction of the arrow 19a in FIG. 4 is transmitted as the force in the direction of the arrow 19c, the force of the connecting rod 40e is transmitted to the hard sliding member 36e via the seat plate member 32ae, and the bottom surface 50be is moved. This is directly received, and the upper end of the window glass 25e is prevented from greatly opening outside. There is an advantage that the stopping force is greater than that in the case where a considerably hard elastic body 34 is arranged in the middle as shown in FIG. 8A and FIG. 8C, the bent portion 53e of the guide rail 50e and the elastic member
The elastic body of the sliding element 31be of the jacket member 31e located between
An annular bulged portion 37e corresponding to the bulged portion 37 in FIG. 7 is formed in the facing portion 34e, and is applied to the contact surface 35e of the elastic body 34e having the through hole 56 as shown in FIG. 8A, 8C, and 9, the same operations and functions as described with reference to FIGS.

Next, the glass 25 and the shoe 30 in FIG.
11, 12 and 13 showing examples which are relatively different from each other in the configuration of the connecting portion 27 with FIG. In these figures, a connecting portion 33f at one end of the connecting rod 40e is formed with a male screw, a female screw is formed on the side of the seat plate member 32ae, and the two are screwed together to form a detachable connecting portion 33f. They are united. Pressing member 41f at the other end of connecting rod 40e
Fig. 4 shows the shape of a hexagonal head with a normal bolt.
As in the case of (1), the glass 25e and the shoe 30e can be integrated via the connecting rod 40e.

In the above description, the elastic member 34e and the sliding member 36e shown in FIGS. 12 and 13 are provided with through holes 56 and 57 for tool insertion (operation) at the center, respectively. These are similar to those shown in FIGS. Also, two through holes 58 provided on the bottom surface 50be of the guide rail 50e are through holes for tool insertion, and the through holes 5 in the upper and lower two shoes 30e.
At positions corresponding to 7 and 57, for example, at positions where the window glass 25e is adjusted for maintenance and inspection, an interval is provided so as to correspond to the shoe 30e. By doing so, the deep end face 59 of the connecting rod 40e is exposed to the through holes 56 to 58. Therefore, if a tool engaging portion, for example, a hexagonal hole or hexagonal pillar is formed therein, a tool such as a hexagonal wrench or a box is used from the right side indoor side in FIG. Various adjustments can be made, such as loosening the tightening force of the connecting rod and tilting the window glass 25e. The lower shoe 30 in FIG.
In order to provide the same function to e, a through hole is provided in the sliding member 36e, and the connecting rod 40e and the seat plate member 32ae are formed as two members as shown in FIG. It is preferable to form a tool engaging portion in the tool. Furthermore, the through holes 5 in the elastic body 34e
6 is formed large and a space is formed inside, and when the annular bulging portion 37e which is the other party is pressed, the central through hole 56e is formed.
Since the reaction force from the position (1) becomes small, the inclination in the section (O) to (A) to (C) in FIG. 9 becomes small, and the degree of sliding of the shoe 30e can be adjusted. FIG.
0, 11, 12, and 13 are functionally described above with reference to FIGS.
The parts that are considered to be the same as or equivalent to those described above are denoted by the same reference numerals as those in the above-mentioned figures, and the letter e is added to the parts, and redundant description will be omitted.

[0016]

As described above, according to the present invention, the shoe 30 moves up and down along the guide rail 50. In this case, the dimension W between the upper wall inner surface 50a and the bottom surface 50b of the guide rail 50 is reduced. Even if there is a large or small variation in the vertical direction, the space between the elastic body 34 and the sliding member 36 is relatively expanded and contracted in a state where the pressure is partially in contact with each other, so that the shoe 30 is softly attached to the inner surface of the guide rail 50. It has the effect of moving up and down lightly while being familiar, and supporting the window glass 25 without rattling even if it stops halfway.

In addition, even if the upper portion of the window glass 25 receives the suction force in the outdoor direction 19a during high-speed running, the shoe 3
The opposing surfaces 34a and 36a of the elastic body 34 and the sliding member 36 at 0 are entirely in contact with each other, counter the suction force in a state where a large reaction force is generated, and also have an effect of preventing a large opening at the top of the window glass 25. is there.
