Description

  The present invention relates to a slide door that can be opened and closed on a side part of a vehicle, etc., and has a lift arm whose middle part is rotatably supported by a base plate, and a window regulator that raises and lowers a window glass at the other end of the lift arm. An intermediate stopper mechanism capable of restricting the movement of the sliding door in the middle of opening within a certain range, and when the opening of the window glass exceeds a certain level, the intermediate stopper mechanism moves the sliding door in the opening direction. The present invention relates to a sliding door provided with an intermediate stopper control mechanism that restricts the fixed range.

  As shown in FIG. 4, a wind glass 1 is provided on a slide door 3 such as a vehicle so as to be movable up and down. For this reason, when the sliding door 3 is opened with the window glass 1 lowered, if an object is inserted into the window of the sliding door 3, the object is sandwiched between the window frame 7 and the pillar 9 of the sliding door 3. May be damaged.

  Therefore, in order to avoid this situation, it has been proposed to provide an intermediate stopper mechanism and stop the sliding door that is moving in the opening direction in the middle of opening when the window glass 1 is lowered below a predetermined position. .

  An example of this sliding door is shown in FIG. In this figure, an intermediate stopper control mechanism 11 provided in the window regulator 16 is arranged such that a cable (inner wire) corresponds to the descending amount while the window glass 1 is lowered by a predetermined amount L (for example, 150 mm) from the fully closed state. Pull 13 in. On the other hand, when the moving stroke of the cable 13 reaches the set value, the drawing of the cable 13 is stopped.

  The intermediate stopper mechanism 15 is connected to the intermediate stopper control mechanism 11 by a cable 13. The intermediate stopper mechanism 15 is driven by the intermediate stopper control mechanism 11 and stops the slide door 3 moving in the opening direction in the middle of opening. The X arm type window regulator 16 drives the window glass 1 in the vertical direction.

  Here, the window regulator 16 and the intermediate stopper control mechanism 11 will be described with reference to FIG. The base plate 51 is attached to the inner panel of the slide door. A lift arm 55 is rotatably supported on the base plate 51 using pins 53.

  A driven gear 57 is fixed to one end of the lift arm 55 so as to overlap the lift arm 55 by welding or the like. The driven gear 57 meshes with a pinion 61 provided on an output shaft of a motor (including a gear box) 59 provided on the base plate 51 and is driven to rotate.

  A roller 63 is provided at the other rotating end of the lift arm 55, and this roller 63 is movable in the horizontal direction by a guide 67 formed on a lift arm bracket 65 attached to the lower end of the window glass 1. Is engaged.

  One end of the equalizer arm bracket 69 is rotatably fitted to the pin 53. The other end of the equalizer arm bracket 69 is fixed to the inner panel of the slide door.

  A spindle 71 passing through the lift arm 55 is rotatably provided between the pin 53 of the lift arm 55 and the roller 63, and a first end extending in the direction of the lift arm bracket 65 is provided at one end of the spindle 71. An equalizer arm 73 is fixed.

  A second equalizer arm 75 extending in the direction of the equalizer arm bracket 69 is fixed to the other end of the spindle 71. Accordingly, the first and second equalizer arms 73 and 75 are integrated with each other via the spindle 71.

  A roller 77 movably engaged with a guide 67 of the lift arm bracket 65 is provided at the distal end portion of the first equalizer arm 73, and an equalizer arm bracket 69 is formed at the distal end portion of the second equalizer arm 75. A roller 81 movably engaged with the guide 79 is provided.

In the window regulator 16 having such a configuration, when the motor 59 is driven, the lift arm 55 rotates around the pin 53 and moves the window glass 1 up and down.
Next, the configuration of the intermediate stopper control mechanism 11 will be described in detail with reference to FIG. The intermediate stopper control mechanism 11 is provided in the window regulator 16. A bell crank-shaped control lever 93 is pivotally attached to a bracket 91 fixed to the base plate 51 by welding or the like.

  In addition, a cam plate 95 is fixed on the surface of the lift arm 55 on which the driven gear 57 is overlapped with the driven gear 57. A cam surface 95 d is formed on the outer edge of the cam plate 95. The cam surface 95 d is in contact with the tip end portion 93 a which is one rotation end portion of the control lever 93. The cable 13 is connected to the other rotating end of the control lever 93. Further, the control lever 93 is in a direction in which the tip end portion 93 a abuts against the cam surface 95 d of the cam plate 95 by the biasing force of the spring 95 whose one end is locked to the bracket 91 and the other end is locked to the control lever 93. Is being energized.

  Accordingly, when the lift arm 55 rotates and the window glass 1 moves up and down, the cam plate 95 also rotates, and the control lever 93 that contacts the cam surface 95d of the cam plate 95 rotates. The cable 13 is advanced and retracted by the rotation of the control lever 93.

The cam surface 95d of the cam plate 95 pulls in the cable (inner wire) 13 and moves the cable 13 according to the descending amount while the window glass 1 descends by a predetermined amount L (for example, 150 mm) from the fully closed state. When the stroke reaches the set value, the cable 13 is set to stop drawing.
JP 2001-288916 A (FIGS. 1 and 2)

  However, the cam plate 95 and the control lever 93 of the intermediate stopper control mechanism 11 configured as shown in FIG. 6 are provided on the same surface side as the surface on which the lift arm 55 of the base plate 51 of the window regulator 16 is provided. Therefore, the control lever 93 needs to be arranged so as not to interfere with the lift arm 55. For this reason, the intermediate stopper control mechanism 11 requires a large space in the vertical plane direction of the window glass 1. Referring to the configuration shown in FIG. 6, in order to prevent interference with the lift arm 55, the control lever 93 is provided at a location away from the base plate 51 of the window regulator 16, and therefore the bracket 91 that rotatably supports the control lever 93. Is required.

Therefore, there is a problem in that the layout of other devices (for example, a door check device) provided in the door interior space is limited.
The present invention has been made in view of the above problems, and an object of the present invention is to provide a slide door that increases the degree of freedom in layout of the interior space of the door.

The invention according to claim 1, which solves the above problem, has a lift arm whose intermediate portion is rotatably supported by a base plate, and a window regulator that raises and lowers the window glass at the other end of the lift arm, and a slide that is being opened An intermediate stopper mechanism that can restrict the movement of the door in the opening direction within a certain range, and when the opening of the window glass exceeds a certain range, the intermediate stopper mechanism restricts the movement of the sliding door in the opening direction within the certain range. An intermediate stopper control mechanism to be driven, a driven gear is fixed to one end of the lift arm, and the base plate is provided with a pinion that meshes with the driven gear and drives the driven gear . in the face opposite to the lift arm is provided a surface of the base plate, before A control lever rotatably provided between the rotation axis of the lift arm and the rotation axis of the pinion; and a surface of the base plate opposite to the surface on which the lift arm is provided; A cam plate that is fixed to a rotating shaft that rotates together with the lift arm, and that has a cam surface that is in sliding contact with the tip of the control lever, and that pushes the tip of the control lever to rotate the control lever; A cable in which one end of the inner wire is locked to the control lever, transmits the opening of the window glass to the intermediate stopper mechanism, and restricts the movement of the sliding door in the opening direction to the intermediate stopper mechanism. to consist of a sliding door according to claim.

  When the window glass is opened using a regulator, and the window glass opens beyond a certain level, the intermediate stopper control mechanism is activated, and the intermediate stopper mechanism is used to regulate the movement of the sliding door in the middle of opening within a certain range. To do.

  When the window glass is moved up and down by rotating the lift arm, the pin that is the rotation axis of the lift arm also rotates and the cam plate also rotates. As the cam plate rotates, the control lever also rotates. The movement of the control lever, that is, the opening and closing of the window glass is transmitted to the intermediate stopper mechanism side via the inner wire of the cable.

According to the first aspect of the present invention, the intermediate stopper control mechanism is provided on the surface of the base plate opposite to the surface on which the lift arm is provided, so that the intermediate stopper is not considered without interference with the lift arm. A control mechanism can be provided in the window regulator.

Therefore, the space in the wind glass ascending / descending plane direction is more vacant than before, and the degree of freedom of layout of the door interior space is increased.
Ca Mupureto is attached directly to a pin that rotates with a rotation axis the lift arms of the lift arm. Accordingly, the cam plate can be reduced in size as compared with the conventional case where the cam plate is attached to the side surface of the lift arm, so that the intermediate stopper control mechanism can be reduced in size.

  4 to 6 showing the present embodiment and the conventional example are the window regulator and the intermediate stopper control mechanism, and the other parts are the same, so the explanation of the window regulator and the intermediate stopper control mechanism of this embodiment will be given. The description of other parts is omitted.

  First, the window regulator 116 will be described with reference to FIG. The base plate 151 is attached to the inner panel of the slide door. A lift arm 155 is rotatably supported on the base plate 151 using pins 153.

  A driven gear 157 is fixed to one end of the lift arm 155 so as to overlap the lift arm 155 by welding or the like. The driven gear 157 meshes with a pinion 161 provided on the output shaft of a motor (including a gear box) 159 provided on the base plate 151 and is driven to rotate.

  A roller 163 is provided at the other rotating end of the lift arm 155, and this roller 163 can move in a horizontal direction on a guide 167 formed on a lift arm bracket 165 attached to the lower end of the window glass 101. Is engaged.

  An equalizer arm bracket 169 is provided on the inner panel of the slide door. A spindle 171 passing through the lift arm 155 is rotatably provided between the pin 153 of the lift arm 155 and the roller 163, and a first end extending in the direction of the lift arm bracket 165 is provided at one end of the spindle 171. An equalizer arm 173 is fixed.

  A second equalizer arm 175 extending in the direction of the equalizer arm bracket 169 is fixed to the other end portion of the spindle 171. Therefore, the first and second equalizer arms 173 and 175 are integrated with the spindle 171.

  A roller 177 movably engaged with a guide 167 of the lift arm bracket 165 is provided at the distal end of the first equalizer arm 173, and an equalizer arm bracket 169 is formed at the distal end of the second equalizer arm 175. A roller 181 movably engaged with the guide 179 is provided.

In the window regulator 116 having such a configuration, when the motor 159 is driven, the lift arm 155 rotates around the pin 153 to raise and lower the window glass 101.
Next, the intermediate stopper control mechanism 111 will be described with reference to FIGS. The intermediate stopper control mechanism 111 of the present embodiment is provided on the surface of the base plate 151 opposite to the surface on which the lift arm 155 is provided, that is, on the inner panel side of the door of the base plate 151. A through hole 151 a is formed in the base plate 151. The above-described pin 153 is rotatably disposed in the through hole 151a, and the above-described lift arm 155 is fixed to one end portion of the pin 153 with the base plate 151 interposed therebetween. A hole 203 is formed on one end side of the cam plate 201, and a cam surface 205 and a flange portion 207 that covers the cam surface 205 are formed on the other end side. A hole 203 of the cam plate 201 is fixed to the other end side of the pin 153 (on the inner panel side of the door of the base plate 151) by a method such as press fitting. Therefore, the lift arm 155, the pin 153, and the cam plate 201 are integrated, and the lift arm 155 and the cam plate 201 rotate together.

  A bracket 211 is provided on the base plate 151, and a control lever 215 is rotatably provided on the bracket 211 using a pin 213. An abutting portion 216 that can abut against the cam surface 205 of the cam plate 201 is formed on one rotating end side of the control lever 215.

  A cable locking portion 217 is formed on the bracket 211, and one end portion of the outer casing 223 of the cable 221 is locked to the cable locking portion 217. The inner wire 225 on one end side of the cable 221 is locked to a cable locking portion 219 formed on the control lever 215. The other end side of the cable 221 is connected to the intermediate stopper mechanism.

  Further, the contact portion 216 of the control lever 215 contacts the cam surface 205 of the cam plate 201 by the biasing force of the spring 241 whose one end is locked to the control lever 215 and the other end is locked to the bracket 211. It is biased in the direction of contact. Note that the flange portion 207 of the cam plate 201 is provided so as to prohibit the movement when the contact portion 216 of the control lever 215 moves away from the base plate 151.

  Accordingly, when the lift arm 155 rotates and the window glass 101 moves up and down, the cam plate 201 also rotates, and the control lever 215 that contacts the cam surface 205 of the cam plate 201 rotates. As the control lever 215 rotates, the inner wire 225 of the cable 221 moves forward and backward.

  The cam surface 205 of the cam plate 201 draws the inner wire 225 of the cable 221 and moves the inner wire 225 according to the lowered amount while the window glass 101 is lowered by a predetermined amount L (for example, 150 mm) from the fully closed state. When the stroke reaches the set value, the inner wire 225 is set to stop drawing.

  According to such a configuration, the intermediate stopper control mechanism 111 is provided on the surface of the base plate 151 opposite to the surface on which the lift arm 155 is provided, so that the intermediate stopper control mechanism 111 is not considered without considering interference with the lift arm 155. The mechanism 111 can be provided in the window regulator 116. Therefore, the space in the wind glass ascending / descending plane direction is more vacant than before, and the degree of freedom of layout of the door interior space is increased.

  Further, the cam plate 201 is directly attached to a pin 153 that is a rotation axis of the lift arm 155 and rotates together with the lift arm 155. Therefore, the cam plate 201 can be reduced in size compared to the conventional case where the cam plate is attached to the side surface of the lift arm, and thus the intermediate stopper control mechanism 111 can be reduced in size.

  The present invention is not limited to the above embodiment. In the above embodiment, the slide door having an X arm type window regulator having a so-called lift arm and an equalizer arm has been described. However, the present invention can also be applied to a slide door having a so-called single arm type window regulator having only a lift arm. Needless to say.
