Description

  The present invention relates to a mechanism for detecting a descending amount of a window glass of an automobile or the like.

  As shown in FIG. 5, a wind glass 1 is provided on a slide door 3 such as a vehicle so that the window glass 1 can be moved up and down. Therefore, 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, an intermediate stopper mechanism, a pinching prevention mechanism, and the like are provided, and when the window glass 1 is lowered below a predetermined position, the sliding door that is moving in the opening direction is stopped in the middle of opening. Has been proposed.

An example of the intermediate stopper mechanism is shown in FIG.
First, the intermediate stopper control mechanism 11 as a detection mechanism for detecting the amount of fall of the window glass 1 detects the amount of fall while the window glass 1 is lowered by a predetermined amount L (for example, 150 mm) from the fully closed state. Pull in the cable (inner cable) 13. On the other hand, when the moving stroke of the cable 13 reaches the set value, the drawing of the cable 13 is stopped. However, even in this situation, the wind glass 1 can be lowered.

  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 configuration of the intermediate stopper control mechanism (window glass descending amount detection mechanism) 11 will be described in detail with reference to FIG. A base plate 31 is fixed to the inner panel of the slide door 3, and pins 33 are erected on the base plate 31. A first lever 35 and a second lever 37 are rotatably attached to the pin 33.

The spiral spring 39 is wound around the pin 33, one end 39 a is hooked on the first lever 35, and the other end 39 b is hooked on the second lever 37.
A roller 41 is provided at the rotating end of the first lever 35, and this roller 41 is engaged with a guide 17 provided at the lower part of the window glass 1 so as to be movable in the horizontal direction in the figure. . The cable 13 is connected to the second lever 37.

  In the conventional sliding door 3, when the fully closed window glass 1 is lowered using the window regulator 16, the first lever 35 also rotates counterclockwise in FIG. 6 as the window glass 1 is lowered. . Further, since the second lever 37 is also connected to the first lever 35 via the spiral spring 39, the second lever 37 rotates counterclockwise and pulls in the cable 13.

  When the moving stroke of the cable 13 reaches the set value, the rotation of the second lever 37 is restricted and the second lever 37 cannot rotate following the first lever 35. However, even in this situation, by elastically deforming the spiral spring 39 so as to reduce the diameter, only the first lever 35 can be rotated counterclockwise, and the window glass 1 can be lowered.

Accordingly, when the window glass 1 is lowered by a predetermined amount L or more from the fully closed state, the intermediate stopper control mechanism 11 pulls the cable 13 by a predetermined amount, and the intermediate stopper mechanism 15 is put into an operating state. When the sliding door 3 is moved in the opening direction in this state, the sliding door 3 is stopped halfway by the intermediate stopper mechanism 15 and cannot be opened any more. That is, in the sliding door 3, even if the window glass 1 is lowered and an object is inserted into the window of the sliding door 3, there is always a space between the window frame 7 and the pillar 9 of the sliding door 3. Therefore, it is possible to avoid a situation where an object inserted into the window is pinched (see, for example, Patent Document 1).
JP 2000-160930 (2nd page, FIG. 7)

  When the intermediate stopper control mechanism 11 is used, it is necessary to reduce the diameter of the spiral spring 39 in order to keep the window glass 1 lowered even after the window glass 1 is lowered by a predetermined amount L from the fully closed state. Load increases. For this reason, there is a problem that a large operating force is required.

  SUMMARY OF THE INVENTION An object of the present invention is to provide a window glass descending amount detecting mechanism that eliminates the disadvantages of the conventional window glass descending amount detecting mechanism. That is, an object of the present invention is to realize a window glass descending amount detection mechanism capable of reducing the operating force of the window regulator.

  According to a first aspect of the present invention, in a window glass descending amount detecting mechanism for detecting the descending amount of the window glass that is moved up and down by the window regulator, the upper arm portion and the lower arm are pivotally mounted on the vehicle body side so as to be pivotable in the vertical direction. A control lever having a bifurcated driven arm composed of a portion, an upper limit stopper that can be contacted by the control lever and prohibits further upward rotation of the control lever, and the control lever A lower limit stopper that prohibits further downward rotation of the control lever, and urging the control lever in a reverse direction with a neutral position as a boundary, so that the control lever is moved to the upper limit stopper or the lower limit. A spring that abuts against the stopper, and is provided on the window glass side, abutting against the control lever And when the control lever is in the lower limit position where it abuts against the lower limit stopper, only the upper arm portion of the driven arm can abut against the pressing member, and the control lever The window glass lowering detection mechanism is characterized in that only the lower arm portion of the driven arm can be in contact with the pressing member when the upper limit position is in contact with the upper limit stopper.

When the window glass is closed, the control lever is in the upper limit position, and only the lower arm portion of the driven arm can come into contact with the pressing member.
When the window glass is lowered from the state in which the window glass is closed, the pressing member pushes the lower arm of the driven arm of the control lever against the biasing force of the spring, and the control lever rotates downward and the spring The urging force is used to move the lower limit position to contact the lower limit stopper. At this time, only the upper arm portion of the driven arm of the control lever can come into contact with the pressing member.

  When the window glass is raised from this state, the pressing member pushes the upper arm of the driven arm of the control lever against the biasing force of the spring, the control lever rotates upward, and the upper limit stopper is pressed by the spring biasing force. Move to the upper limit position where it touches.

  If the pressing member is set to push the control lever when the window glass is lowered by a predetermined amount, it can be detected whether the window glass is lowered by a predetermined amount depending on whether the control lever is at the upper limit position or the lower limit position.

  According to the first aspect of the invention, since the pressing member resists the urging force of the spring only while the control lever rotates the control lever from the upper limit position or the lower limit position to the neutral position, a load is applied to the window regulator. Therefore, the window regulator operating force can be reduced as compared with the conventional example.

  Embodiments of the present invention will be described with reference to the drawings. The present embodiment includes not only an intermediate stopper mechanism that stops the sliding door that moves in the opening direction, but also a fully-open stopper mechanism that prohibits the movement of the sliding door at the fully-open position.

(Intermediate stopper mechanism)
FIG. 4 conceptually shows the configuration (plan view) of the stopper mechanism portion in the embodiment of the present invention. In this figure, the guide rail 51 is provided on the vehicle body side and is directed in the opening / closing direction of the slide door. The rollers 53 and 55 are movably fitted to the guide rail 51 and are rotatably supported by the roller arm 50.

  The support plate 57 is attached to the door panel of the slide door, and the base plate 61 is attached to the support plate 57 and the roller arm 50. Accordingly, the slide door is guided by the guide rail 51 and can move between the fully closed position and the fully open position.

  On this base plate 61, there are provided an intermediate stopper mechanism 63 capable of stopping the sliding door moving in the opening direction halfway, and a fully opening stopper mechanism 65 for holding the sliding door in the fully open position. Here, the support plate 57 is located on the outer side (window side), and the guide rail 51 is located on the inner side (vehicle interior side). FIG. 4 shows a state where the slide door is in the fully closed position.

  An intermediate striker 67 that engages with the intermediate stopper mechanism 63 is provided on the vehicle body side. When the sliding door moves from the fully closed position toward the fully opened position, if the window glass is opened by a predetermined amount or more, the pole 71 of the intermediate stopper mechanism 63 and the intermediate striker 67 come into contact with each other. The movement in the above opening direction is restricted.

  Here, the intermediate stopper mechanism 63 will be described in detail. On the base plate 61, a pole 71 capable of contacting the intermediate striker 67 is rotatably supported by a pin 71c. The pole 71 is urged in the direction of arrow D by a first urging means (not shown). Further, a buffer plate 71b is fixed to a contact portion of the pole 71 with the intermediate striker 67.

  Further, on the base plate 61, a first hook 73 is rotatably provided by a pin 73c. The first hook 73 engages with the protrusion 71a of the pole 71 rotated to a position where it does not contact the intermediate striker 67 (the rotation position shown in FIG. 4) with the protrusion 73a, and the pole 71 is restrained at that position. To do. The first hook 73 is urged in a direction E in which the protrusion 73 a engages the protrusion 71 a of the pole 71 by a second urging means (not shown).

When the protrusion 73a of the first hook 73 is engaged with the protrusion 71a of the pole 71, the rotation of the pole 71 in the arrow D direction is prohibited.
A cable 75 that is driven by an intermediate stopper control mechanism described later is connected to the first hook 73.

  The pole pushback member 68 is disposed on the vehicle body side. The pole push-back member 68 abuts on the pole 71 in the slide door that is moving in the closing direction, and rotates the pole 71 from a position where it can abut against the intermediate striker 67 to a position where it cannot abut. Further, the stopper 77 protruding from the base plate 61 abuts on the pole 71 whose restriction by the first hook 73 is released, and stops the pole 71 at this abutting position.

(Fully open stopper mechanism)
The full opening stopper mechanism 65 will also be described in detail with reference to FIG. A fully-open striker 69 that is engaged with the fully-open stopper mechanism 65 when the slide door moves to the fully-open position is disposed on the vehicle body side. On the other hand, the base plate 61 is provided with a latch 81 formed with an engaging groove 81a that can be engaged with and disengaged from the fully-open striker 69 so as to be rotatable by a pin 81c. The latch 81 is urged in the direction of arrow F by third urging means (not shown).

  Here, the position of the latch 81 shown in FIG. 4 is a position that can be engaged with the fully-open striker 69, and the latch 81 in a state not restrained from the outside is shown in FIG. It is biased to return to position.

  On the base plate 61, a second hook 83 is rotatably provided by a pin 83c. The second hook 83 is engaged with the protrusion 81b of the latch 81 that is engaged with the full-open striker 69 and rotated to the lock position with the protrusion 83a, and restrains the latch 81 at the lock position. The second hook 83 is urged in a direction G in which the protrusion 83 a engages with the protrusion 81 b of the latch 81 by a fourth urging means (not shown).

  When the protrusion 83a of the second hook 83 engages with the protrusion 81b of the latch 81, the rotation of the latch 81 in the direction of arrow F is prohibited. In the case of an automobile, the second hook 83 is connected to a cable 85 that is driven by an inner handle, an outer handle, or the like. Although not shown, the latch 81 is restricted from rotating in the F direction from the position shown in FIG.

(Window regulator)
In the present embodiment, the slide door includes a wire type power window regulator as shown in FIG. The configuration of the power window regulator itself is the same as that generally known. In FIG. 1, the guide 101 is arranged so that the longitudinal direction thereof coincides with the up-and-down direction of the window glass 102 (up and down direction in FIG. 1). The guide 101 has a substantially rectangular cross section, and a slit 101a is formed in the longitudinal direction at the center of one side of the cross section. An upper bracket 103 is provided on the upper end side of the guide 101, and a lower bracket 104 is provided on the lower end side of the guide 101. Both the upper bracket 103 and the lower bracket 104 are attached to a door inner panel (not shown). Yes.

  Two sliders 105A and 105B are fitted to the guide 101 so as to be movable up and down, and a slider base 106 is connected to the sliders 105A and 105B. The slider base 106 and the lower portion of the window glass 102 are fixed using screws (bolts and nuts). Thereby, the window glass 102 can be moved up and down along the guide 101.

  A drum base 108 is disposed on the side of the guide 101. The drum base 108 is formed with a drum holding portion formed of a columnar space, and a drum 109 having a spiral groove formed on a cylindrical surface is rotatably held therein. An intermediate portion of the wire 112 is wound around the groove on the cylindrical surface of the drum 109. The motor 110 drives the drum 109 to rotate.

  One end of the wire 112 is wound on the slider base 106 after being wound around an upper pulley 113 that is rotatably supported on the upper bracket 103. The other end side of the wire 112 is wound on the slider base 106 after being wound around a lower pulley 114 rotatably supported on the lower bracket 104.

  In this window regulator, the drum 109 is rotated by driving the motor 110. As the drum 109 rotates, one end side of the wire 112 is fed out from the drum 109 and the other end side is wound around the drum 109. Due to the circulating motion of the wire 112, the slider base 106 moves along the guide 101, and the window glass 102 is raised and lowered.

(Intermediate stopper control mechanism)
As shown in FIG. 1, the guide 101 is provided with an intermediate stopper control mechanism 151 that detects the descending amount of the window glass 102. The configuration of the intermediate stopper control mechanism 151 will be described with reference to FIGS.

  The bracket 152 is fixed to the guide 101, and a control lever 153 is pivotally attached to the bracket 152 with a pin 154. The control lever 153 can rotate in the clockwise direction in FIG. 2 to an upper limit position (solid line position in FIG. 2) that contacts an upper limit stopper 152a formed by bending a part of the bracket 152, and in the counterclockwise direction, the bracket 152 Can be rotated to a lower limit position (a two-dot chain line position in FIG. 2) that abuts on a lower limit stopper 152b formed by bending (cutting and raising) a part thereof.

  On the other hand, the slider base 106 is provided with a pressing member 160 that presses the control lever 153. In this embodiment, as the pressing member 160, a pair of upper and lower pressing members 160a and 160b are formed by bending a part of the slider base 106 to the back side of the paper surface of FIG. The pressing members 160a and 160b are formed with an inclination with respect to a horizontal plane as shown in FIG. 2 so that the control lever 153 can be smoothly pushed.

  The control lever 153 has a bifurcated pushed arm 153a pushed by the pushing member 160. When the control lever 153 is at the upper limit position, only the lower arm portion 153b of the pushed arm 153a is the pushing member. When the control lever 153 is in the lower limit position, only the upper arm portion 153c of the pushed arm 153a can come into contact with the pressing member 160.

  Synthetic resin coating layers 161 and 162 are provided on the lower arm portion 153b and the upper arm portion 153c (contact portion with the pressing member 160) of the driven arm 153a of the control lever 153 in order to ensure smooth sliding. Is formed. In addition, in order to restrict the contact portion of the control lever 153 with the pressing member 160 from moving in the direction of the rotation center axis of the control lever 153, the ends of the pressing members 160a and 160b are bent to have flanges 160c and 160d. Is formed.

  A hook 153d is formed at the center of the branch of the arm 153a to be pushed of the control lever 153, and a hook 152c is formed on the bracket 152 on the right side of the center of the pin 154 in FIG. A tension spring 163 is hooked between 153d and 152c.

  The tension spring 163 functions as a turnover spring that urges the control lever 153 in the reverse direction with respect to the neutral position, and is a position where the tension spring 163 overlaps with a straight line connecting the center of the hook 152c and the pin 154. However, when the tension spring 163 is tilted upward from the neutral position at the neutral position of the control lever 153, the tension spring 163 drives the control lever 153 to the upper limit position, and when tilted downward, the control lever 153 is moved to the lower limit position. I will drive you.

  Here, the formation position of the pressing member 160 on the slider base 106 is lower when the pressing member 160 is lowered integrally with the slider base 106 and the window glass 102 is lowered to a predetermined position (lowering amount L). The pressing member 160b on the side is set to a position that drives the control lever 153 to the lower limit position. Further, when the window glass 102 rises to a predetermined position, the upper pressing member 160a pushes the control lever 153 upward beyond the neutral position, and is set to a position where the control lever 153 is driven to the upper limit position.

  One end of the inner wire 75a of the cable 75 is locked to the swing arm 153e of the control lever 153, and the movement of the control lever 153 is transmitted to the intermediate stopper mechanism side. The cable 75 is fixed to the cut-and-raised portion 152d of the bracket 152 so that one end of the cable 75 is opposed to the control lever 153 with the end thereof being lower than the horizontal direction, and the inner wire 75a is pulled out when the window glass 102 is lowered. It has become.

(Operation of this embodiment)
In the intermediate stopper mechanism 63, when the sliding door is in the fully closed position and the window glass 102 is in the fully closed state, the pole 71 rotated to a position where it cannot contact the intermediate striker 67, as shown in FIG. One hook 73 is engaged by the urging force of the second urging means.

  Here, when the motor 110 is driven to lower the fully closed window glass 102 and the slider base 106 is lowered in FIG. 1, the pressing member 160 is also lowered. When the window glass 102 is lowered to a predetermined position, the lower pressing member 160b drives the control lever 153 to the lower limit position. As a result, the first hook 73 is driven in the direction of separating from the pole 71 (counterclockwise in FIG. 4), and the engagement between the first hook 73 and the pole 71 is released.

  Therefore, when the pole pushing-back member 68 is not restrained, the pole 71 is rotated to a position where it comes into contact with the stopper 77 by the urging force of the first urging means, and can come into contact with the intermediate striker 67.

  When the sliding door with the window glass 102 lowered to a predetermined position is moved in the opening direction, the pole 71 moves away from the pole pushing-back member 68 and moves to a position where it abuts against the stopper 77 as shown by a two-dot chain line. Rotate until. When it further moves, the pole 71 comes into contact with the intermediate striker 67, and further movement of the sliding door is prohibited (intermediate lock state).

  To release the intermediate lock state, the slide door is moved in the closing direction, returned to the position shown in FIG. 4, and the window glass 102 is raised from a predetermined position. By this returning operation, the back surface of the pole 71 is pushed by the pole pushing back member 68 provided on the vehicle body side, the pole 71 rotates in the direction opposite to the arrow D, and the first hook 73 is engaged with the pole 71 again, The intermediate lock state is released.

  Next, the operation of the fully open stopper mechanism 65 will be described. When the sliding door is not fully opened, the latch 81 is in a position (position shown in FIG. 4) that can be engaged with the fully open striker 69 by the urging force of the third urging means.

When the sliding door moves in the fully open direction, the fully open striker 69 engages with the engaging groove 81a of the latch 81, and further, the latch 81 rotates in the clockwise direction in FIG.
When the latch 81 rotates to the position indicated by the two-dot chain line, the second hook 83 engages with the latch 81 by the urging force of the fourth urging means, and the fully open lock prohibiting the rotation of the latch 81 in the arrow F direction. It becomes a state.

To release the fully open lock state, operate the inside handle and outside handle. Then, the cable 85 is pulled in, the engagement of the second hook 83 with the latch 81 is released, the latch 81 can be rotated in the direction of arrow F, and the fully open lock state is released. For this reason, the slide door can be moved in the closing direction.

  In the sliding door according to the present embodiment, a wire type window regulator is used and the amount of lowering of the window glass 102 is indirectly obtained by using the elevation of the slider base 106, so the intermediate stopper control mechanism 151 is made small. Can be

  Furthermore, since the pressing member 160 resists the biasing force of the tension spring 163 only while the control lever 153 rotates the upper limit position or lower limit position to the neutral position, a load is applied to the window regulator. Therefore, the window regulator operating force can be reduced as compared with the conventional configuration in which the diameter of the spiral spring is reduced.

  Further, the pressing member 160 is formed by bending a part of the slider base 106, and the stoppers 152a and 152b for stopping the control lever 153 at the lower limit position and the upper limit position are formed by bending a part of the bracket 152. The number of points can be reduced and the configuration can be simplified. In addition, since the control lever 153 having the bifurcated pushed arm 153a pushed by the pressing member 160 is used, the configuration of this portion is also simplified.

  Further, since the flanges 160c and 160d are provided on the pressing member 160 and the contact portion of the control lever 153 with the pressing member 160 is restricted from coming off in the direction of the rotation center axis of the control lever 153, the sliding door is strongly opened and closed. The intermediate stopper control mechanism 151 can be surely operated even when it is subjected to the impact of when traveling on a rough road.

  Further, since the synthetic resin coating layers 161 and 162 are formed on the contact portion of the control lever 153 with the pressing member 160, a good sliding state can be obtained, and the intermediate stopper control mechanism 151 can be reliably operated. It can be secured.

  Furthermore, since the cable 75 is fixed to the cut-and-raised portion 152d of the bracket 152 so that one end of the cable 75 is opposed to the control lever 153 with the horizontal direction downward, water entering the slide door is No entry into 75. For this reason, the malfunction of the intermediate stopper control mechanism 151 due to freezing does not occur.

  The present invention is not limited to the embodiments described above. For example, a fully open stopper mechanism is not always necessary. Further, although the tension spring is used as the turnover spring, any spring may be used as long as it exhibits this function. Furthermore, a part of the slider base is bent to form a pressing member, or a part of the bracket is bent to form a stopper, but it goes without saying that these may be configured as separate parts.

  In the above embodiment, the bracket for pivotally attaching the control lever is directly fixed to the guide. However, the bracket may be indirectly fixed to the guide by fixing the bracket to the door panel or other members. . Further, the door panel may be used as a bracket. In short, it is only necessary that the bracket and the guide are integrally arranged so that they cannot be displaced relatively.

  In the above embodiment, the covering layers 161 and 162 are formed at the contact portions of the control lever 153 with the pressing member 160 on the lower arm portion 153b and the upper arm portion 153c. The part 153b and the upper arm part 153c may be brought into direct contact with the pressing member 160.
