JP 2006-28973 A WO2002 / 75090 JP-A-11-303503 JP 2005-307529 A JP 2006-76457 A JP 2001-342774 A

  A window regulator that raises and lowers the window glass of an automobile door is supported by a guide rail that is mounted on the inner panel of the door in the vertical direction, and moves up and down along the guide rail, and is fixed to the lower end of the window glass to support the window glass. Carrier plate, an inner cable for raising and lowering that a cable end is locked to the carrier plate, an upper and lower guide member that changes the direction of the inner cable at the upper and lower ends of the guide rail, and for raising and lowering A cable drive mechanism that winds one of the inner cables and feeds the other (see Patent Document 1). The inner cable is slidably guided by an outer casing (conduit) between the upper and lower guide members and the cable driving mechanism.

  A carrier plate used in such a cable type window regulator generally includes a base made of a metal plate, a guide portion made of a synthetic resin insert-molded to the base, and a cable locking portion (patent) Literature 2, Patent Literature 3). The guide portion is a portion that slides with the guide rail. A resin carrier plate formed entirely of synthetic resin or fiber reinforced resin has also been proposed (Patent Document 4). Further, when the carrier plate is raised or lowered, the upper and lower guide members and the carrier plate are brought as close as possible to reduce the dead stroke. There has also been proposed a structure in which the portions are obliquely crossed and locked (see FIG. 4 of Patent Document 5).

  On the other hand, in a device for driving a slide door of an automobile using a control cable, a synthetic resin end holder that locks the cable ends of the front and rear (front and rear) inner cables is used as a member for connecting the door to the front and rear ends. A metal plate bracket having a curved portion is used (Patent Document 6).

  Each of the conventional carrier plates has a relatively wide surface arranged in parallel with the window glass. This flat form is based on a traditional form in which the surfaces are brought into contact with the lower part of the window glass and fixed with two bolts, etc. The glass holder fixed to the lower end of the window glass is a carrier plate. The type of window regulator (see Patent Document 1) that is connected to is continuously adopted. The “plate” named “carrier plate” is also based on its form. Moreover, the carrier plate of the type which reduces the dead stroke of patent document 3 is not greatly deviated from the basic form.

  However, in the case of a window regulator using a glass holder, a wide surface is not actually required. Further, in the window regulator developed by the present inventors and using a glass run channel or the like without using a guide rail, a guide portion that slides with the guide rail is unnecessary. However, a cable locking part is necessary.

  On the other hand, the slide door bracket of Patent Document 6 does not attach a window glass, and may require strength to support the guide roller, so a metal plate is press-molded without using a synthetic resin. It has a simple form.

  In view of the above-described changes in the situation surrounding the window regulator, it is an object of the present invention to provide a carrier plate for a cable-type window regulator that has a simple configuration and can reduce dead strokes. It is another object of the present invention to provide a window regulator that has a simple overall configuration and has a small dead stroke, thereby reducing a required space such as an automobile door.

  The carrier plate according to the present invention (Claim 1) is a carrier plate used in a cable type window regulator, and is an end locking portion for locking the cable end of the rising cable and an end for locking the cable end of the falling cable. A locking portion is provided, and at least one of the end locking portions is constituted by a curved metal plate.

  In such a carrier plate, for a rising cable having a surface that comes into contact with the front surface of the glass holder, having a mounting hole formed therein, protruding forward from the base portion, and having a tip curved downward And an end locking portion for a descending cable that protrudes forward from the base portion and has a tip that curves upward (Claim 2).

  Further, it is preferable that a temporary placement portion for supporting a glass holder is provided at the left end and / or the right end of the base portion, and the temporary placement portion is constituted by a bent piece continuous with the base portion. ). Further, the left end and / or the right end of the base portion is provided with an abutting portion for abutting and positioning on the side surface of the glass holder, and the abutting portion is constituted by a bent piece continuous with the base. Those are preferred (claim 4). In that case, a metal plate piece extends from the rear end of the left and / or right contact portion to the left and / or right, and the metal plate piece constitutes a temporary placement portion that supports the glass holder. It is further preferable (Claim 5).

  The window regulator of the present invention (Claim 6) drives any one of the carrier plates described above, the rising cable and the lowering cable locked to the end locking portion of the carrier plate, and the rising cable and the lowering cable. And a cable guide for changing the direction of the cable.

  Since the carrier plate according to the present invention (Claim 1) is made of a metal plate having at least one of the end locking portions for locking the ascending cable and the descending cable, the configuration is simple and easy to manufacture. It is. Moreover, since a metal plate has high intensity | strength, it can be made thin. Therefore, at the stroke end on the end locking portion side, it is easy to approach the cable guide, which contributes to the reduction of the dead stroke. When both the ascending and descending end locking portions are made of a curved metal plate, the configuration is further simplified. Further, the dead stroke can be reduced at both the rising end and the falling end.

  The carrier plate has a surface that comes into contact with the front surface of the glass holder, a base portion in which an attachment hole is formed, and an end for the rising cable that protrudes forward from the base portion and has a tip curved downward. In the case of including a latching portion and an end latching portion for the descending cable that protrudes forward from the base portion and has a tip curved upward (Claim 2), the configuration of the entire carrier plate is provided. It can be simplified, and the dead stroke can be reduced at both the rising end and the falling end.

  In the case where the left and / or right end of the base is provided with a temporary placement portion that supports the glass holder, and the temporary placement portion is constituted by a bent piece continuous with the base portion (Claim 3), When the carrier plate is attached to the window glass to which the glass holder is attached, the weight of the window glass is temporarily supported by the temporary placement portion of the carrier plate supported by the cable, and operations such as screw tightening can be performed in that state. Therefore, the assembly work is facilitated. Further, positioning in the vertical direction is easy. In the case where the temporary placement portions are provided at the left and right ends, after the carrier plate is attached to the window glass, the carrier plate does not rotate and the angular position is restricted even if there is only one attachment hole.

  In the case where the left end and / or the right end of the base portion is provided with a contact portion for contacting and positioning the side surface of the glass holder, and the contact portion is constituted by a bent piece continuous with the base portion. (Claim 4) facilitates positioning in the left-right direction when the carrier plate is attached to the window glass. In addition, the rotation angle is restricted after mounting. When the contact portions are provided on the left and right, positioning is easier.

  When a metal plate piece extends from the rear end of the left and / or right contact portion to the left and / or right, and the metal plate piece constitutes a temporary placement portion that supports the glass holder According to (Claim 5), the contact portion and the temporary placement portion can be configured integrally, and the configuration of the entire carrier plate can be further simplified.

  Since the window regulator of the present invention (Claim 6) includes any of the carrier plates described above, the configuration of the entire window regulator is simplified, and assembly work is facilitated. Also, the dead stroke can be reduced. As a result, it is possible to reduce the installation space for the doors of automobiles. In the same space, the window glass can be moved up and down longer.

  Next, embodiments of the carrier plate and the window regulator of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view showing an embodiment of a carrier plate according to the present invention together with a glass holder and a cable, FIGS. 2a and 2b are front and side views of the carrier plate, respectively, and FIG. 3 is an embodiment of a window regulator according to the present invention. 4a and 4b are a side view and a front view of the main part when the window glass in the window regulator is raised, respectively, and FIGS. 5a and 5b are respectively lowered the window glass in the window regulator of FIG. It is the principal part front view and principal part side view when doing.

  The carrier plate 10 shown in FIG. 1 is a component for connecting the window glass W and the cables 11 and 12 for driving up and down. The carrier plate 10 has a base portion 14 that comes into contact with the front surface of the glass holder 13 fixed to the lower edge of the window glass W, and projects forward from the upper end of the base portion, and the tip 15a is curved downward. An end locking portion 15 for the rising cable 11 and an end locking portion 16 for the falling cable that protrudes forward from the lower end of the base portion 14 and has a tip 16a curved upward are provided.

  Further, the carrier plate 10 includes contact pieces 17 and 17 for positioning by contacting the side surface of the glass holder 13 at the left and right ends of the base portion 14. Each contact piece 17 is formed by bending a metal plate piece continuous with the base portion 14 backward, and temporarily placed outward from the rear end of the contact piece (left side is left and right side is right). The parts 18, 18 extend. The contact piece 17 and the temporary placement portion 18 may be only on one side. In this embodiment, the base portion 14, the upper and lower end locking portions 15, 16, the contact piece 17, and the temporary placement portion 18 are formed by press forming such as punching or bending a single metal plate as a whole. Can be manufactured easily.

  An attachment hole 19 for attachment to the glass holder 13 is formed at a position on the right side in the substantially central portion of the base portion 14. The end locking portions 15 and 16 are provided in the vicinity of the left end of the base portion 14 so as not to interfere with a screw (see reference numeral 20 in FIG. 2 b) or a bolt that passes through the mounting hole 19. In this embodiment, the upper end locking portion 15 extends forward obliquely upward, and its tip 15a is curved downward in an arc shape to lock the cable end 21 of the rising cable 11.

  The curved end 15a of the end locking portion 15 for the rising cable 11 is formed with a substantially L-shaped introduction groove 22 through which the cable portion passes when the cable end 21 is arranged on the inner surface of the end 15a. ing. The introduction groove 22 is a substantially L-shaped notch including a horizontal groove 22a cut out to the side edge of the end locking portion 15 and a vertical groove 22b extending upward along an arc from the end of the horizontal groove 22a. It is a groove.

  The end locking portion 16 for the descending cable has a vertically symmetrical form with the end locking portion 15 for the rising cable. However, in this embodiment, the entire lower edge of the base portion 14 is bent obliquely downward in the same manner as the end locking portion 16, and the tip is slightly curved upward except for the end locking portion 16. Yes. The portion 23 extending obliquely forward serves as a stopper that comes into contact with the rubber cushion (see reference numeral 24 in FIG. 5) when the window glass reaches the descending end.

  As the ascending cable 11 and the descending cable 12, a cable in which metal strands are twisted together, particularly an inner cable of a pull control cable can be used. The cable ends 21 and 21 are cylindrical parts fixed to the ends of the cables by casting or caulking. The conventional window regulator also uses a cylindrical cable end, but the cylindrical axis is oriented in the front-rear direction (inside / outside of the car), along with the axial direction of the guide pulley that changes the direction of the cable. Is provided with an end locking portion. However, in the carrier plate 10 shown in FIG. 1, the cylindrical axis is locked in the left-right direction (the front-rear direction of the automobile).

  The glass holder 13 in FIG. 1 includes a glass holding portion 32 having a groove 31 into which the lower end of the window glass W is inserted at the upper end, and a plate-like fixing portion 33 fixed in contact with the base portion 14 of the carrier plate 10. It has. The fixing portion 33 is a portion inserted between the left and right contact pieces 17, 17 of the carrier plate 10, and the left and right side surfaces thereof are in contact with the contact piece 17. However, a gap may be provided. The left and right side surfaces of the lower portion of the fixing portion 33 are tapered so as to narrow downward. As a result, when the window glass W is assembled from above the carrier plate 10, a guide action is exerted, and left and right positioning is facilitated.

  Further, the glass holder 13 is provided with a temporary placement step 34 that is placed on the temporary placement portion 18 of the carrier plate 10 so as to protrude from the fixing portion 33 to the left and right. A guide piece 35 extending obliquely downward is provided in front of the temporary placement step 34. The guide piece 35 has a guide action of drawing the carrier plate 10 toward the glass holder 13 when the window glass W is lowered from the upper side to approach the carrier plate 10. This facilitates the positioning of the glass holder 13 and the carrier plate 10 in the front-rear direction (inward and outward direction of the automobile). The inner end surface of the guide piece 35 may be guided by the outer surface of the contact piece 17. The glass holder 13 is usually molded from a synthetic resin. A cylinder 36 or a nut in which a female screw is formed is fixed to the center portion of the fixing portion 33 by insert molding. However, the carrier plate 10 and the glass holder 13 can be connected with a simple through-hole and using bolts and nuts.

  2a and 2b show a state in which the glass holder 13 is placed on the carrier plate 10 and the screws 20 are coupled to each other. In the attached state, the left and right temporary placement steps 34 of the glass holder 13 are placed on the upper end of the temporary placement portion 18 of the carrier plate 10, so that the carrier plate 10 and the glass are fixed even if they are fixed by one screw 20. The mutual rotation of the holder 13 is prevented. As shown in FIG. 2 b, a gap 37 is opened between the groove 31 of the glass holder 13 and the window glass W, and a cushion sheet or filler for protecting the glass is interposed in the gap 37.

  Since the carrier plate 10 configured as described above is formed from a single metal plate, it has a very simple configuration, is easy to manufacture, and is inexpensive. Furthermore, since the upper and lower end locking portions 16 and 17 are formed of metal plates, for example, when attached to the window regulator 40 of FIG. 3, the accessibility to the cable guides 41 and 42 is high. Therefore, useless strokes, so-called dead strokes, can be reduced.

  Further, since the axial center of the cylindrical cable end 21 is parallel to the window glass W and faces substantially in the horizontal direction, the cables 11 and 12 swing back and forth (in the direction of arrow R in FIG. ) Is forgiven. When used in a curved glass window regulator, the angles of the cables 11 and 12 and the window glass W change as the carrier plate 10 moves up and down, but if the cables 11 and 12 can swing back and forth, the cable The root portions of the cables 11 and 12 attached to the end 21 are not bent in the front-rear direction, and durability is improved.

  Next, with reference to FIG. 3, an embodiment of the window regulator 40 including the carrier plate 10 described above will be described. The window regulator 40 shown in FIG. 3 includes upper, lower, left and right cable guides 41, 42, 43, and 44 attached to an inner panel of an automobile door, and a cable 45 stretched in an approximately eight shape by these four cable guides. A cable driving device 46 that circulates and reciprocates the loop of the cable and left and right carrier plates 10L and 10R provided in the middle of the cable 45 are provided. Guide rails for guiding the carrier plates 10L and 10R are not employed. Moreover, the outer casing (conduit) which guides a cable is not employ | adopted.

  The left side of the window regulator 40 in FIG. 3 corresponds to the front side of the automobile. Therefore, “left” and “right” of the window regulator 40 and the carrier plates 10L and 10R in FIG. 3 correspond to “front” and “rear” of the automobile. The inner panel is disposed on the front side (the vehicle inner side) in FIG. 3, but is not shown here. Therefore, the window regulator 40 of FIG. 3 is provided at the right door toward the front of the automobile. The window regulator provided on the left door is different from the left and right sides in FIG.

  Reference numeral 47 in FIG. 3 is a connecting bar that connects the upper left and right cable guides 41 and 43 to restrict the positional relationship. In the case of the window regulator 40 that does not include a guide rail, the four cable guides 41 to 44 are separated before being attached to a panel such as an inner panel. It ’s easy to get together. Further, the connecting bar 47 is provided with a hooking portion 48 for hooking the lower cable guides 42 and 44. For this reason, the four cable guides 41 to 44 can be held by the single connecting bar 47, and the conveyance and assembly work are facilitated. The connection bar 47 can be left as it is after the window regulator 40 is assembled to the panel, or it can be removed and reused after the assembly.

  In this window regulator 40, one end of the loop of the cable 45 arranged in an 8-character shape is locked to the drum of the cable driving device 46, extends toward the upper right, and is turned downward by the cable guide 43 at the upper right. The first cable 45a is extended to the right, and the other end is locked to the right carrier plate 10R. The other end is locked to the right carrier plate 10R, extends downward, and is turned by the lower right cable guide 44. A second cable 45b extending to the upper left, changed in direction by the upper left cable guide 41 and extending downward, the other end being locked to the left carrier plate 10L, and one end locked to the left carrier plate 10L; A third cable that extends downward and is redirected by the lower left cable guide 42 and is locked to the other end of the drum of the cable driving device 46. Consisting of a 5c.

  In this case, the portion locked to the right carrier plate 10R of the first cable 45a and the portion locked to the left carrier plate 10L of the second cable 45b are the rising cable 11 of FIG. Further, the portion locked to the carrier plate 10R on the right side of the second cable 45b and the portion locked to the carrier plate 10L on the left side of the third cable 45c are the descending cable 12 of FIG. The ends of the first cable 45a and the third cable 45c on the cable driving device 46 side are wound around the drum, and the cable ends are locked in the locking holes of the drum.

  The cable driving device 46 includes a motor and a speed reducer for reciprocatingly driving the drum in the same manner as the conventional one. Further, the cable driving device 46 includes a tension mechanism 50 for taking the slack of the loop of the cable 45. The tension mechanism 50 is fixed to the coil portion 51 rotatably disposed in the housing and torsion coil springs including left and right arms 52 and 52 extending from the coil portion, and to the end portions of the arms 52 and 52. It comprises guide members 53 and 53 each having an arcuate guide groove. When the cable 45 is slack, the tension mechanism 50 causes the arms 52 and 52 to expand like an imaginary line by the urging force of the torsion coil spring, thereby increasing the cable 45 length. As a result, the tension is restored to the cable 45.

  Each of the upper left, upper right and lower right cable guides 41, 43, 44 includes a shaft 54 fixed to a panel such as an inner panel, and a pulley 55 provided rotatably on the shaft, as shown in FIG. The pulley type is composed of a guide plate 56 that is externally provided between the pulley and the panel. However, a slide type as described later may be used. In addition to reducing friction with the panel when the pulley 55 rotates, the guide plate 56 supports a claw piece 57 having an L-shaped cross section protruding from the periphery of the guide plate 56 as shown in FIG. The claw piece 57 is for preventing the cable from dropping from the guide groove on the peripheral edge of the pulley.

  5A and 5B, the lower left cable guide 42 includes a so-called slide guide 59 having an arcuate guide groove 58, a set screw 61 for fixing the slide guide to the panel 60, and a slide guide. And a rubber cushion 24 provided at the upper end of the. A pulley type can also be used. The slide guide 59 can be formed of a synthetic resin. At the left and right ends of the slide guide 59, locking claws 62 that engage with the panel 60 and act to prevent rotation are provided. Reference numeral 63 in FIG. 5 b denotes a nut that is screwed with the set screw 61.

  In the window regulator 40 described above, when the drum of the cable driving device 46 rotates clockwise, the third cable 45c is wound around the drum, and the first cable 45a is sent out from the drum. As a result, the loop of the 8-shaped cable circulates in the direction of arrow D, the left and right carrier plates 10L, 10R descend, and the windows open. When the drum rotates in the reverse direction and the loop of the cable 45 circulates in the direction of the arrow U, the left and right carrier plates 10L and 10R are similarly raised and the windows are closed.

  At the rising end of the window glass W, as shown in FIGS. 4a and 4b, even if the left carrier plate 10L approaches the pulley 55 of the upper left cable guide 41, interference does not occur. The same applies to the upper right cable guide 43 and the right carrier plate 10R, as indicated by the imaginary line in FIG. Further, as shown in the lower right of FIG. 3, the right carrier plate 10 </ b> R can approach to the vicinity of the pulley 55 of the lower right cable guide 44 at the lower end. Further, as shown in FIGS. 5a and 5b, the left carrier plate 10L and the slide guide 59 can also be brought close to each other.

  Therefore, the space | interval of the upper cable guides 41 and 43 and the lower cable guides 42 and 44 can be made small, and a dead stroke can be reduced.

  In the carrier plate 10 shown in FIG. 1 and the like, it is formed only of a metal plate, but a synthetic resin may be partially used. For example, the whole except for the upper and lower end locking portions can be made of synthetic resin, and both or one or both of the upper and lower end locking portions can be made of a metal plate. The upper and lower end locking portions may be integrally formed. In addition to press molding, it can also be formed by die casting. Further, in the carrier plate 10, the cylindrical cable end is locked toward the left and right (front and rear of the vehicle), but is locked toward the front and rear (inside and outside of the vehicle) or up and down. May be. Furthermore, a spherical cable end can be adopted.

  Moreover, in the said embodiment, although the carrier plate 10 is attached to the glass holder 13 with one screw or a volt | bolt, you may attach with two or more screws or volt | bolts.

  In the window regulator 40 of FIG. 3, the cable guides 41 to 44 are arranged at four places, upper, lower, left and right, but a window regulator of a type arranged only in the upper and lower directions may be used. In that case, it is preferable to provide in the center part of the left-right direction (front-back direction of a motor vehicle) of a window glass. In addition, a pair of left and right guide rails can be employed in a window regulator having four upper, lower, left and right cable guides. In a window regulator provided with two upper and lower cable guides, one guide rail disposed at the center in the left-right direction can be employed. When the carrier plate is guided by the guide rail, for example, the base portion 14 of the carrier plate 10 shown in FIG. 1 is extended to the left and right, and a guide portion that slides on the guide rail is provided by a synthetic resin or the like. Furthermore, a conduit for guiding the cable 45 between the cable guides 41 to 44 or between the cable guides 42 and 43 and the cable driving device 46 may be provided.
