Description

  The present invention provides a vehicle glass in which a pulley is disposed at the rising end of a window glass, a retainer is disposed at a descending end, a movement locus of the endless belt is defined, and the endless belt is driven by a motor to raise and lower the window glass. The present invention relates to a lifting device, and more particularly to a vehicle glass lifting device with improved assembly to an inner panel.

  A window regulator that raises and lowers the window glass of an automobile is disposed between an outer panel and an inner panel that constitute a door panel of the automobile. The window glass moves up and down while being guided by a pair of side frames. The window regulator drives the window glass to move up and down by moving the window glass support portion (fastening portion) fixed to the window glass up and down with an endless belt or a tubular wire (hereinafter referred to as endless belt). As this window regulator, there are a wire type guideless window regulator in which the window glass support is not guided by the guide rail, and a window regulator with guide in which the window support is moved up and down by being guided by the guide rail.

  Patent Document 1 discloses a wire-type guideless window regulator. In this conventional window regulator, an endless wire is wound around four guide members in an eight-letter shape, a part of the wire is wound around a drum, and the drum is rotated in the forward and reverse directions to thereby move the wire. Move along an 8-shaped trajectory. And by fixing the window glass support part at two positions of the wire at the part along the moving direction of the window glass in the wire movement locus, the window glass support part is moved by the movement of the wire driven by the drum. Drive up and down.

  When assembling this conventional window regulator to the inner panel, the wires are bundled with a belt separate from the window regulator, i.e., it is hard to prevent the wires from getting tangled in the band, and the window regulator is removed from the hole provided in the inner panel. It is inserted into the space between the panel and the outer panel and attached to the inner panel.

JP 2006-348627 A

  However, in the above-mentioned Patent Document 1, when assembling the window regulator to the inner panel, the wires are bundled using a separate belt, so that the parts cost is high and the space between the inner panel and the outer panel is high. There is a problem that workability is poor to remove the belt inside.

  This invention is made | formed in view of this problem, Comprising: It aims at providing the glass raising / lowering apparatus for vehicles with low components cost and the excellent assembly | attachment property to an inner panel.

  The glass lifting device for a vehicle according to the first invention of the present application is a glass lifting device for a vehicle, which is attached to an inner panel of the vehicle and lifts and lowers the window glass. A first guide member that can be driven and rotated by the movement of the endless belt and is arranged on the side where the window glass rises to define the locus of the endless belt; and the window glass is wound around the endless belt. A second guide member which is disposed on the descending side and defines the trajectory of the endless belt; a drive unit which meshes with the belt teeth to move the endless belt; the first guide member; A carrier bracket which is fixed to the endless belt at a portion between the guide member and connected to the window glass; and And having a portion with a clamp that detachably engaged to said endless belt between the catcher is fixed to the rear bracket, or provided the driving unit and the first guide member.

  In this case, it is preferable that the clamp is a recess provided in the carrier bracket and into which a part of the endless belt can be fitted.

  A glass lifting device for a vehicle according to a second invention of the present application is a glass lifting device for a vehicle which is attached to an inner panel of a vehicle and raises and lowers a window glass, and meshes with the endless belt having belt teeth on the inner surface and the belt teeth A first guide member that can be driven and rotated by the movement of the endless belt and is arranged on the side where the window glass rises to define the locus of the endless belt; and the window glass is wound around the endless belt. A second guide member which is disposed on the descending side and defines the trajectory of the endless belt; a drive unit which meshes with the belt teeth to move the endless belt; the first guide member; A carrier bracket which is fixed to the endless belt at a portion between the guide member and connected to the window glass; and And having a clamp for engaging detachably with the housing of the turbocharger rear bracket and the drive unit.

  In this case, the clamp includes a protrusion provided on one of the carrier bracket and the driving portion, and a fitting portion provided on the other of the carrier bracket and the driving portion to fit the protrusion. It is preferable.

  According to the first invention of the present application, the clamp fixed to the carrier bracket is engaged with the endless belt between the holder and the pulley, and in this state, for example, with the motor, from the hole of the inner panel, Insert it into the space between the outer panel and assemble it to the inner panel. As a result, when the window regulator is assembled, the endless belt can be prevented from drooping, so that the endless belt is not entangled and the attaching operation to the inner panel is extremely easy. And since a clamp can be shape | molded integrally with a carrier bracket, component cost can be reduced. In addition, since the clamp can be engaged with an arbitrary position between the holder and the pulley in the endless belt, the engagement position can be appropriately adjusted in order to facilitate handling. Thereby, for example, when the clamp is engaged in the vicinity of the pulley, the position of the pulley from the motor can be defined, and when the pulley is assembled to the inner panel, it can be easily attached to the assembly hole of the inner panel.

  The above effects are the same even when the clamp is configured to detachably engage the carrier bracket and the motor housing as in the second invention of the present application.

  Hereinafter, embodiments of the present invention will be specifically described with reference to the accompanying drawings. FIG. 1 is a diagram showing a state in which the vehicle glass lifting apparatus according to the embodiment of the present invention is installed on the right door of the rear seat of the automobile (viewed from inside the vehicle), and FIG. 2 is a diagram showing the inner panel. It is. The automobile door 1 includes a pair of side frames 3 and an upper frame 4 at the upper end of the window frame. The window glass 2 is guided by the side frame 3 to move up and down, and the upper end position is restricted by the upper frame 4. Has been.

  The window regulator 10 is disposed between an outer panel (not shown) on the vehicle door outer side and an inner panel 5 on the vehicle inner side. The window regulator 10 includes a pulley 14 disposed above, a retainer 15 disposed below, a drum 12 of the drive unit 11 disposed in the middle in the vertical direction, the pulley 14, the retainer 15, and the drum 12. And an endless belt 16 that is stretched over the three points. When the drum 12 is driven to rotate by the motor 13 of the driving unit 11, the belt 16 is driven to rotate forward and backward. The belt 16 is formed with teeth on the inner surface side, and the teeth of the belt 16 mesh with the teeth formed on the outer surface of the drum 12 and further mesh with the teeth provided on the peripheral surface of the pulley 14. Yes. The retainer 15 has a circumferential surface (half circumferential surface) on which the belt slides. The movement locus of the belt 16 is determined by the pulley 14, the retainer 15, and the drum 12, and the movement locus between the pulley 14 and the retainer 15 is the same as the up-and-down direction of the window glass 2. Of the movement trajectory of the belt 16, a large load for raising the window glass acts on the folding point of the upper end, and therefore a pulley 14 having teeth on the peripheral surface is used, and the folding point of the lower end is used. Since the application of the load is small, a retainer 15 that does not have teeth and has a peripheral surface for simply sliding the belt smoothly is used.

  For example, a resin carrier bracket 17 is fixed to the belt 16 between the pulley 14 and the retainer 15 by integral molding. Further, a window glass support portion 19 is fixed to the lower edge of the window glass 2, and the support portion 19 and the carrier bracket 17 are fixedly connected by a bolt 18.

  As shown in FIG. 2, the inner panel 5 has a hole 22 for fixing the pulley 14 to the inner panel 5 with bolts and nuts (not shown). That is, a bolt is fixed to the pulley 14, and the bolt 14 is inserted through the hole 22 into the inner surface of the inner panel 5. The bolt 14 is tightened with a nut from the inner side of the inner panel 5. Fixed to the panel 5. Similarly, the housing 50 of the drive unit 11 is fixed to the inner panel 5 with bolts and nuts through holes 21 formed in the inner panel 5.

  On the other hand, the retainer 15 is fixed to the inner panel 5 by being hooked on the inner panel 5 through a hole 23 formed in the inner panel 5. The inner panel 5 is provided with a working hole 20 for a worker to put a hand in the space between the inner panel 5 and the outer panel in order to perform these operations.

  FIG. 3 is a view showing the window regulator 10 (vehicle glass lifting device) shown in FIG. 1 with the door portion omitted. A pulley 14 having teeth formed on its peripheral surface is disposed at the rising end of the window glass, and a retainer 15 having a smooth semicircular sliding surface having no teeth formed at the falling end of the window glass. Is arranged. Further, a drum 12 having teeth formed on the peripheral surface is disposed at an intermediate position between the pulley 14 and the retainer 15, and teeth are formed on the inner surface of the pulley 14, the drum 12 and the retainer 15. The endless belt 16 is stretched over. The inner surface teeth of the endless belt 16 mesh with the teeth of the pulley 14 and the teeth of the drum 12. The drum 12 is rotationally driven in the forward and reverse directions by the motor 13, whereby the endless belt 16 that meshes with the drum 12 reciprocates. A carrier bracket 17 is fixed to a portion between the pulley 14 and the retainer 15 in the moving range of the endless belt 16, and the carrier bracket 17 supports the lower end of the window glass 2 as shown in FIG. 1. The supporting part 19 is connected by a bolt 18. As a result, when the endless belt 16 is raised or lowered in the movement range between the pulley 14 and the retainer 15, the glass window 2 is raised or lowered via the carrier bracket 17 and the support portion 19.

  For example, the endless belt 16 is formed with teeth on one surface of a rubber belt such as chloroprene rubber or acrylonitrile butadiene rubber (NBR), and a nylon woven fabric is provided so as to cover the surface on which the teeth are formed. It has been processed. The endless belt is reinforced by embedding a plurality of core wires extending in the longitudinal direction of the belt in the rubber belt. Further, the carrier bracket 17 is made of, for example, resin, and is fixed to the endless belt 16 by integral molding.

  This window regulator 10 is a door 1 as shown in FIG. 1 in a state where a pulley 14, a retainer 15, a carrier bracket 17, a drum 12 and a motor 13 are attached to an endless belt 16 shown in FIG. It will be transported to. Then, the worker usually holds the heaviest motor 13 and inserts the window regulator 10 into the space between the inner panel and the outer panel through the work hole 20. At this time, since the motor 13 does not rotate unless energized, the positions of the drum 12 and the motor 13 on the endless belt 16 do not change. Further, since the carrier bracket 17 is fixed to the endless belt 16, the position with respect to the endless belt 16 does not change in the same manner. However, the pulley 14 moves on the endless belt 16 between the drum 12 and the carrier bracket 17 as indicated by an arrow in FIG. Thus, if the pulley 14 moves, the operation | work which attaches the window regulator 10 to the back side of the inner panel 5 will become difficult. Moreover, since the endless belt 16 hangs down for a long time, the handling thereof is complicated.

  Therefore, in the present embodiment, the clamp 30 is fixed to the carrier bracket 17 as shown in FIG. The clamp 30 is formed with a thin recess 31 at its tip, and the endless belt 16 is restrained by inserting the endless belt 16 into the recess 31. The restraining position of the endless belt 16 is a portion between the drum 12 and the pulley 14. In addition, as shown in FIG. 6, this restraint mode only fits the endless belt 16 in the recess 31, so that the relative movement in the belt longitudinal direction between the clamp 30 and the endless belt 16 is Is possible. However, by constraining the endless belt 16 with the clamp 30, the distance between the drum 12 and the pulley 14 inevitably falls below a certain size (A in FIG. 5). The clamp 30 can be formed of resin. Since the carrier bracket 17 is also formed by integral molding (casting molding) on the endless belt 16 with resin, when the carrier bracket 17 is molded with resin, the clamp 30 is also molded by resin molding in the same process. do it. It should be noted that by setting the tip side portion of the portion of the clamp 30 where the recess 31 is formed thin, the tip side resin portion has elasticity, and the endless belt 16 can be sandwiched with elasticity. it can.

  Next, the operation of the window regulator 10 thus configured will be described. As shown in FIG. 5, with the endless belt 16 fitted and clamped in the recess 31 of the clamp 30, the operator holds the motor 13 and inserts the window regulator 10 into the work hole 20. First, the motor 13 and the drum 12 are fixed to the hole 21 (see FIG. 2) provided in the inner panel 5 from the back side of the inner panel 5.

  Next, as shown in FIG. 7, with the endless belt 16 clamped by the clamp 30, the pulley 14 is fixed to the hole 22 (see FIG. 2) provided in the inner panel 5 from the back side of the inner panel 5. At this time, as shown in FIG. 9, the pulley 14 is fixed to the inner panel 5 on the front side (inner side) of the inner panel 5 by the rotation shaft of the pulley 14 passing through the hole 22. Thereafter, the concave portion 31 of the clamp 30 is pulled out in the width direction of the endless belt 16 to release the clamp of the endless belt 16 by the clamp 30 as shown in FIG. Then, the clamp 30 is detached from the endless belt, and the endless belt 16 is slightly slackened particularly in the lower half as shown in FIG. 8, but the retainer 15 is suspended from the lower end thereof. Therefore, as shown in FIG. 11, the retainer 15 is pulled downward, the endless belt 16 is pulled, and the retainer 15 is fixed to the mounting hole 23 (see FIG. 2) of the retainer 15 from the back side of the inner panel 5.

  As a result, as shown in FIG. 11, the pulley 11 and the retainer 15 are arranged at predetermined positions on the inner panel 5, and the endless belt 16 is pulled at three positions including the drum 12 on the pulley 11 and the retainer 15. It can be wound around.

  In this embodiment, until the pulley 14 is attached to the inner panel 5, the clamp 30 provided on the carrier bracket 17 clamps the endless belt 16, so that the endless belt 16 droops greatly during assembly work. The window regulator 10 can be easily inserted between the inner panel 5 and the outer panel through the work hole 20. Further, since the dimension of “A” shown in FIG. 5 is regulated to a certain value or less by the clamp of the endless belt 16, the pulley 14 shown in FIG. 7 can be easily attached. Furthermore, after the drum 12 and the pulley 14 are attached, the retainer 15 can be positioned easily by simply pulling the retainer 15 downward, so that the retainer 15 can be positioned easily. Installation work is also easy.

  Next, a second embodiment of the present invention will be described with reference to FIGS. The second embodiment is characterized in that the clamp 40 detachably engages the carrier bracket 17 and the housing 50 of the drive unit 11. In the present embodiment, the housing 12a of the drum 12 is adopted as the housing 50 of the drive unit 11. That is, the clamp 40 is provided with a protrusion 41 on the carrier bracket 17 so as to protrude with respect to the carrier bracket 17, and the protrusion 41 is inserted into a ring-shaped fitting portion 43 provided on the drum housing 12 a of the drive unit 11. Thus, the carrier bracket 17 and the drum housing 12a are detachably engaged with each other. The protrusion 41 is formed by cutting out the central portion into two halves, and a large-diameter portion 42 is formed at the tip of these two rods. The ring-shaped fitting portion 43 has an inner diameter larger than the outer diameter of the protrusion 41 in a state where the two protrusions are separated from each other, but this inner diameter is smaller than the outer diameter of the large-diameter portion 42. The two bars can be elastically approached, and when the two bars approach each other, the outer diameter of the large diameter portion 42 is smaller than the inner diameter of the fitting portion 43. Note that the protrusion 41 of the carrier bracket 17 is fitted not in the fitting portion 43 provided in the housing 12a of the drum 12 but in the motor housing 13a as in the above embodiment. It can also be a fitting part of the housing 13a. Also in this case, the carrier bracket 17 and the housing 50 of the drive unit 11 can be detachably engaged.

  Therefore, in the present embodiment configured as described above, the protrusion 41 provided on the carrier bracket 17 is connected to the ring-shaped fitting portion 43 provided on the motor housing 13a or the drum housing 12a from the large diameter portion 42 side. The large diameter part 42 protrudes from the fitting part 43 by inserting in. Since the outer diameter of the large-diameter portion 42 is normally larger than the inner diameter of the fitting portion 43, the carrier bracket 17 and the motor housing 13a or the drum housing 12a are engaged with each other. Further, this engagement can be easily removed by pulling the carrier bracket 17 or the motor housing 13a or the drum housing 12a from the other side, whereby the carrier bracket 17 is detached from the motor housing 13a or the drum housing 12a. .

  Thus, in the present embodiment, the carrier bracket 17 that does not move relative to the endless belt 16 and the drum 12 or the motor 13 (drum housing 12a or motor housing 13a) can be temporarily fixed. Large sagging can be prevented. Further, the pulley 14 can be easily attached after the motor 13 and the drum 12 are attached to the inner panel 5.

  The protrusion 41 with the large diameter portion 42 is not limited to the carrier bracket 17, and may be attached to the motor housing 13 a or the drum housing 12 a, for example, and the fitting portion 43 may be attached to the carrier bracket 17 instead. Further, the engaging means is not limited to those shown in the above embodiments, and various means can be adopted.
