JP5623799B2 - Window regulator - Google Patents

Description

  The present invention relates to a window regulator that moves a window glass up and down. More specifically, the present invention relates to a window regulator used in a car or the like.

  Parts used in vehicles are required to be lighter for reasons such as improved fuel efficiency, and light weight is also required for window regulators. As a light weight type of window regulator, there is no outer casing from the upper and lower ends of the guide rail to the drive unit near the center as a window regulator of the delta type (the motor is near the center of the guide rail). There is a so-called outerless window regulator that is routed to In such an outerless window regulator, a sharp blade is inserted through the gap of the door, and the inner cable not covered by the outer casing (not stored in the outer cable) is cut and suspended by the window. There is a possibility that the glass is dropped downward and the interior of the vehicle is damaged.

  For this reason, Patent Document 1 discloses a window regulator anti-theft protector (hereinafter referred to as a protector) that covers the outer periphery of the control cable as a means for preventing such entry into the vehicle. This protector includes a metal wire braid layer that covers at least a part of the outer peripheral surface of the outer casing, and a rubber-made outer layer that covers the outer periphery of the metal wire braid layer.

  In addition, crime prevention technology to prevent such theft has been advanced and spread in recent years, and vehicle crime prevention theft alarm devices that generate alarm sounds by detecting vibrations and impacts on doors and glass are also widespread. . For this reason, when a vehicle equipped with a vehicle security theft alarm device is stolen, the owner of the vehicle resident in the vicinity of the parked vehicle rushes with an alarm sound, but before the owner arrives at the vehicle It is desirable that the theft work not be completed until the vehicle is taken away.

Patent Publication No. 4021346

Generally, an outerless window regulator is defenseless against both a blade and a clipper because an inner cable is not covered with an outer casing. On the other hand, if the inner cable is housed inside the outer casing, it may not be useful for the clipper as described above, but the advantage is that it cuts off the inner cable more than it is not covered at all. is there. However, when the outer casing is used, the weight of the entire apparatus and the number of parts increase. For example, in the outer casing, when the carrier plate stops at the upper and lower ends of the guide rail as the inner cable is moved in the guide rail axial direction by the driving device, the restraining force (reaction of the tension of the inner cable) is applied from the inner cable to the motor. Force, ie compression force). The inner cable swings in the width direction of the drum when it is wound and fed out to the drum, and comes into contact with the drum-side end of the outer casing. For this reason, the outer casing is required to have rigidity to withstand the compressive force and contact, and the weight increases accordingly. Furthermore, a cushion mechanism using a spring that can absorb the compressive force is used at the end of the outer casing. For this reason, when the window regulator of Patent Document 1 is used, the inner cable cannot be easily cut even if a blade or clipper is used, but the number of parts and weight increase.

  Therefore, an object of the present invention is to provide an outerless window regulator having a simple configuration and high antitheft performance.

  The window regulator according to the present invention includes a carrier plate for holding a window glass, a guide rail for movably guiding the carrier plate, a direction changing member provided at an upper end portion and / or a lower end portion of the guide rail, In a window regulator having an inner cable spanned by a direction change member and connected to the carrier plate, and a driving device for moving the inner cable in the guide rail axial direction, the driving device winds up the inner cable. A drum, and the inner cable is arranged in a substantially straight line between the direction changing member and the drum, and is arranged in a longitudinal direction outside the substantially straight inner cable. The outer tube has an outer tube. The ingredients, at least end portions of the drum side, is characterized in that it is held so as to be swung to follow the swing of the inner cable caused by the winding and unwinding by the drum.

(1) Since the window regulator of the present invention has an outer tube, it has excellent anti-theft properties. In particular, it has better anti-theft properties than conventional outerless window regulators.
Further, since the inner cable is linearly routed from the drum to the direction changing member, the outer tube is not subjected to the restraining force by the motor. Therefore, it is not necessary to hold the outer tube firmly on the drum side or the guide rail side. That is, since simple holding is sufficient, the holding portion can be reduced in weight or space can be saved.
Furthermore, since simple holding is sufficient, if the outer tube is held by the outer holder and the end of the outer tube on the drum side is not fixed (movable freely), the inner cable generated by winding and feeding by the drum The outer tube can be swung following the swing. The straight wiring includes a substantially straight wiring, and includes a slightly bent state in the outer holder when the inner cable moves in the width direction of the drum.

  (2) When the outer holder of such a window regulator holds the vicinity of the end portion on the direction changing member side of the outer tube, the end portion on the drum side of the outer tube becomes free. The outer tube can be swung following the swinging of the inner cable in the drum width direction on the drum by winding and feeding the inner cable. Therefore, it is possible to prevent the outer tube from being worn and the occurrence of vibration caused by the movement of the inner cable being restricted by the outer.

  (3) When the drive device is mounted between the upper end portion and the lower end portion of the guide rail, the position of the drive device is determined. can do. In particular, the position where the driving device is disposed is preferably disposed near the center between the upper end portion and the lower end portion of the guide rail.

(4) Furthermore, the inner cable is protected from the vicinity of the drum by a drum cover that covers the drum so that the inner cable is protected to the vicinity of the drum by the outer tube, and the inner cable can be wound and fed by the drum. When protecting the inner cable until it comes into contact with the drum, even if the outer tube is arranged at a distance from the drum, the inner cable near the drum can be efficiently cut and the outer tube can be protected. And the drum do not collide.

FIG. 3 is a perspective view of the drum cover. 4 is a cross-sectional view taken along the line II of FIG. FIG. 5 is a perspective view showing the back side of the outer holder of FIG. FIG. 6 is a view on arrow A in FIG. 7 is a cross-sectional view taken along the line II-II in FIG.

  FIG. 1 shows a window regulator of the present invention. The window regulator 1 includes a guide rail 2, a carrier plate 3 that is slidably disposed on the guide rail 2 and holds the window glass W, and a drive device 4 that is fixed near the middle of the guide rail 2. ing. Direction change members 5a and 5b are provided at the upper and lower ends of the guide rail 2, respectively. The carrier plate 3 is engaged with a rising inner cable 6 extending upward along the guide rail 2 and a lowering inner cable 7 extending downward. The inner cable 6 for raising and the inner cable 7 for lowering are respectively turned in opposite directions by the direction changing members 5a and 5b, and are respectively locked to the drum 4c (see FIG. 2) of the driving device 4. . In addition, the window regulator 1 in a figure is provided in the door at the right rear of a vehicle body, and has shown a mode that the state which attached was seen from the inside of the vehicle body.

  The window regulator 1 can also be used for a front door of a vehicle body. Furthermore, it may be used for windshields for vehicles such as ships, airplanes, and trains.

  An outer tube 9 is provided in the longitudinal direction of the outer periphery of the rising inner cable 6 in the range from the upper direction changing member 5a to the drum 4c. The outer tube 9 accommodates the rising inner cable 6 therein, prevents the rising inner cable 6 from being cut, and obstructs the cutting thereof. The outer tube 9 is fixed to the guide rail 2 by an outer holder 8. Although not shown, an outer tube 9 can be provided on the outer periphery of the lowering inner cable 7 for further safety. In addition, when the drive device 4 is mounted above the guide rail 2 (when mounted above the center shown in the figure), the vicinity of the drum 4c of the lowering inner cable 7 is also arranged so as to be higher from above. Cutting tool may arrive. Therefore, an outer tube 9 may be provided on the lowering inner cable 7 for a window regulator of the type in which the driving device 4 is mounted on the upper side or the upper end of the guide rail.

  The guide rail 2 is a long metal member extending vertically, and a conventionally known one can be used. In the case of a guide railless window regulator, the outer holder 8 may be attached to a member on the vehicle body side (such as an inner panel or an outer panel).

The carrier plate 3 is provided with a cable locking portion 3a for locking the cable ends 6a and 7a of the rising inner cable 6 and the lowering inner cable 7 at the center. The cable locking portion 3a has a substantially box shape in which the cable end can be accommodated, and is open to the outside of the vehicle body. Then, slits 3b and 3b are formed on the upper and lower side walls forming the box, and the cable ends 6a and 7a are hooked via a biasing member 3c (compression coil spring) for extending the cable. The carrier plate 3 has a cable locking portion 3.
Mounting holes 3d and 3d for fixing the window glass W are formed on both sides centering on a. The carrier plate 3 is preferably integrally formed with a synthetic resin. As a material of the synthetic resin, polybutylene terephthalate (PBT) or polyethylene terephthalate (PET) is preferable, and a material with high wear resistance such as polyoxymethylene (POM) is particularly preferable.

  As shown in FIG. 2, the driving device 4 includes a driving device bracket 4a fixed to the inner surface of the guide rail 2 and a fastener 4g (bolt or the like) from the inner surface of the driving device bracket 4a to the driving device bracket 4a. A drive motor assembly 4b (including a motor, a speed reducer, etc.) having an output shaft that is fixed and projects through the drive device bracket 4a and protrudes to the outside of the vehicle; a drum 4c coupled to the output shaft; The drum cover 4d covers the upper side of the drum 4c.

  Returning to FIG. 1, the drive device bracket 4 a of the drive device 4 is attached near the middle of the upper and lower direction changing members 5 a and 5 b of the guide rail 2. This is a delta type window regulator. On the other hand, although not shown, the drive device 4 can be fixed to the lower end of the guide rail 2 to form a lower end drive type window regulator. In either type of window regulator, the drive device 4 is fixed to the guide rail 2, so that the rising inner cable 6 and the lowering inner cable 7 can be routed substantially linearly. Therefore, an outer casing for guiding the inner cable 6 for raising and the inner cable 7 for lowering is not necessary. The drive device bracket 4a may be attached to a member (an inner panel or an outer panel) on the door side of the vehicle body without being fixed to the guide rail 2.

  As shown in FIG. 3, the drum cover 4d includes a cylindrical peripheral wall that covers the periphery of the drum 4c. The upper end of the peripheral wall is closed by the top surface, and the lower end is open. Openings 4e and 4e for guiding the rising inner cable 6 and the lowering inner cable 7 to the internal drum 4c are formed in two upper and lower portions on the peripheral wall of the drum cover 4d. The openings 4e and 4e are formed to be larger than the swing width so that the edges of the openings do not come into contact with the cables 6 and 7 even when the cables 6 and 7 are swung in the width direction of the drum 4c by winding and unwinding the drum 4c. Yes. Further, protective walls 4f and 4f are formed so as to cover the periphery of the cables 6 and 7 from the opening edges of the openings 4e and 4e. When the outer tube 9 is not provided in the lowering inner cable 7, the protective wall 4f may not be formed in the opening 4e on the lowering side. However, in this embodiment, the protective wall 4f is used for the left and right doors of the vehicle body. The opening 4e and the protective wall 4g are formed on the upper and lower sides.

  The direction changing member 5a provided at the upper end of the guide rail 2 is a pulley. Further, the direction changing member 5b at the lower end is a slide guide. These pulleys and slide guides are conventionally known. In addition, a pulley may be used for the lower direction change member, and a slide guide may be used for the upper part.

  The ascending inner cable 6 and the descending inner cable 7 are conventionally known ones in which a plurality of metal strands are twisted together.

As shown in FIGS. 4 and 5, the holder 8 includes an outer bracket 10 attached to the guide rail 2 and a clip 11 attached to the tip of the outer bracket 10. The outer bracket 10 is a strip-shaped member. The outer bracket 10 has an attachment piece 10a that is an attachment portion to the guide rail 2, and a support that is bent perpendicularly from the front end to the vehicle outer side and that extends in parallel to the attachment piece 10a from the bent front end. It consists of a piece 10b. A locking hole 10c is formed near the tip of the support piece 10b. The outer holder 8 has the support piece 10b extended obliquely upward (FIG. 1).
The mounting piece 10a is mounted below the direction changing member 5a of the guide rail 2. The attachment piece 10a of the outer holder 8 can be attached to a member on the vehicle body side (for example, an inner panel or an outer panel).

  The clip 11 is provided at a plate-like base portion 11a, a protruding portion 11b that protrudes from the surface of the base portion 11a and fits into the locking hole 10c of the support piece 10b, and a distal end of the base portion 11a. And a gripping portion 11c that grips the outer periphery of the elastically. The protruding portion 11b may be configured as a shaft member that can rotate within the locking hole 10c.

  The grip portion 11c is a substantially cylindrical member in which a plate is molded into a cylindrical shape. A gap having a width the same as or slightly smaller than the outer diameter of the outer tube 9 is formed at the tip of the cylindrical plate. Then, the outer tube 9 is pushed in from the gap while the cylindrically shaped plate is opened, and the outer tube 9 is held inside the tubular shape by the repulsive force caused by the pushing. Further, as shown in FIG. 5, the clip 11 has a grip portion 11c sandwiched between a casing cap 12 and a stopper 13 fixed to the outer tube 9 by a fixing means such as adhesion or caulking. 9 is held near the end. The outer tube 9 is prevented from moving in the longitudinal direction by being sandwiched and held between the casing cap 12 and the stopper 13. The clip 11 is preferably formed of a polyamide resin such as polyoxymethylene (POM) or nylon, or a synthetic resin such as polybutylene terephthalate (PBT). In addition, when forming with a metal, you may make it use the holding | grip part 11c which shape | molded the thin metal piece to the cylinder shape, and may clamp the holding part 11c from the outer side after inserting the outer tube 9, and may fix it.

  The support piece 10b is extended obliquely upward so that the clip 11 at the tip is disposed in a region (reference S in FIG. 6) on the back side (inner side) of the carrier plate 3 at the rising end. By arranging in this way, the vicinity of the lower end of the carrier plate 3 or the window glass W is obstructed, and the synthetic resin clip 11 is prevented from being broken by a blade or the like. Further, when the clip 11 is formed of a flexible material, it can bend following a free end shake (an arrow in FIG. 6) of the outer tube 9 described later, and bends by swinging as a base point of the shake. The outer tube 9 can be securely held, and the force applied to the outer tube by winding and feeding the inner cable 6 of the drum 4C can be reduced. Furthermore, if the protruding portion 11b of the clip 11 can rotate within the locking hole 10c, even if an unexpected load is applied to the clip 11 via the outer tube 9, the load can be released in the rotating direction. . Therefore, it is possible to prevent the outer tube 9 from falling off the grip portion 11c due to an unexpected load, or to prevent the clip 11 itself from being damaged. The strip-shaped support piece 10b may be bent in a direction perpendicular to the plate surface to follow the deflection of the outer tube 9.

The outer tube 9 is a member that covers the periphery of the rising inner cable 6 and is not particularly limited as long as it covers the inner cable and is lighter than the outer casing including the metal wire braiding layer. It is possible to use a rigid tube such as a metal pipe, or a tube made of sticky rubber or other material that cannot be easily torn so that cutting is troublesome. It is preferable to use a synthetic resin tube because it is easily available. For example, it is preferably formed of a material such as polypropylene (PP), polyethylene (PE), or polyvinyl chloride (PVC). Moreover, you may use the steel-bar outer which each distribute | arranged so that two straight steel wires may become a parallel and symmetrical position with respect to a longitudinal direction axis | shaft in the synthetic resin outer tube thickness.
As will be described later, the outer tube 9 is preferably flexible so that the lower end (drum 4c side) of the outer tube 9 can easily swing together with the rising inner cable 6. Note that if the outer tube 9 is highly flexible, it may become a source of vibration. Therefore, the entire outer tube 9 and the clip 11 (and the outer bracket 10) may be bent to follow the swing of the rising inner cable 6.

  The outer tube 9 does not cover the outer periphery of the rising inner cable 6 immediately adjacent to the upper direction changing member 5a. The outer tube 9 covers the outer periphery from a position where some space (reference S) is provided from below the upper direction change member 5a (see FIGS. 1 and 6). This is because the lower end of the closed window glass W is disposed in the space S, so that the cutting tool cannot enter without being covered with the outer tube 9. On the other hand, the opposite end is housed in the protective wall 4f of the drum cover 4 (see FIG. 7). Therefore, the drum cover 4 does not have a gap that allows the cutting tool to contact the rising inner cable 6 from the upper end of the guide rail 2 to the drum 4c from the vicinity of the drum 4c until the inner cable 6 contacts the drum 4c.

  FIG. 6 shows a view of FIG. In order to facilitate the explanation, in the figure, the carrier plate 3 is shown by a solid line at the upper limit, and the carrier plate 3 at the original position in FIG. 1 is shown by a two-dot chain line. As shown in FIG. 6, the upper end of the outer tube 9 is held by a holder 8. On the other hand, the other end is not held and is left free. When the rising inner cable 6 is wound / sent out to / from the drum 4c, the rising inner cable 6 swings in the width direction of the drum 4c (see arrow). However, since the outer tube 9 is free except at the upper end, it can bend or swing following the deflection of the inner cable 9. Therefore, the rising inner cable 6 does not come into contact with the end of the outer tube 9 on the drum 4c side and is not damaged (see FIG. 7). Moreover, if the upper end of the outer tube 9 is fixed with the holder 8, the outer tube 9 can shake largely at the lower end.
