  The present invention relates to an opening / closing body opening / closing device having an inner guide that regulates the routing route of an inner cable so as to follow a guide rail.

  2. Description of the Related Art Conventionally, there has been known a window regulator that raises and lowers a window glass attached to a carrier plate along a guide rail by driving an inner cable. In general, in a window regulator for raising and lowering a window glass provided on a vehicle door, a guide rail is formed to be curved in a bow shape in order to raise and lower the window glass in accordance with the shape of the vehicle body. Therefore, in such a window regulator, for example, an inner guide is attached to the guide rail in order to restrict the inner cable routing path along the guide rail (see, for example, Patent Document 1).

  In Patent Document 1, a guide member (inner guide) is provided between both ends of the guide rail, and the inner cable is slidably supported so as to approach the guide rail, thereby being rotatably provided at the upper end of the guide rail. The inner cable guide member such as a pulley and the inner cable groove of the drum of the driving portion provided at the lower end of the guide rail are prevented from being obliquely routed, and abnormal noise is prevented from being generated.

The carrier plate 3 has a fixing hole 31 for fixing a window glass (not shown) with a screw or the like. The carrier plate 3 can be integrally formed with, for example, a synthetic resin or the like, but may be formed by being fixed to each other separately by heat fusion or the like. The material of the carrier plate 3 is not particularly limited to a synthetic resin, and may be a metal or a combination of a metal and a synthetic resin.

  The guide rail 4 is formed so that a thin metal plate such as a substantially rectangular galvanized steel sheet having a predetermined length in the vertical direction is bent in a bow shape so that the window glass moves up and down along a curved path. Yes. For example, as shown in FIGS. 1 and 6, the guide rail 4 is formed such that one end in the width direction is bent substantially at right angles to the concave surface 41 side, and the other end side protrudes to the convex surface 42 side in the opposite direction. A rail portion 43 is formed. The rail portion 43 is formed along the vertical direction of the guide rail 4 and is fitted into a guide groove (not shown) formed in the carrier plate 3.

  The inner cable 5 moves the carrier plate 3 up and down by the driving device 2. When the inner cable 5 is not arranged in the inner guide 6, the pulley 7 and the guide rail 4 provided at the upper end of the guide rail 4 are arranged. It is arranged in a straight line so as to pass the shortest distance between the drums 21 provided at the lower end.

  The pulley 7 functions as a direction changing member for changing the direction of the inner cable 5. The direction changing member is not limited to the pulley 7, and a member known as a guide member for changing the moving direction of the inner cable 5 such as a member having a groove formed in a semicircular shape is adopted.

  Next, the inner guide 6 of this embodiment will be described. The inner guide 6 is for restricting the routing route of the inner cable 5 so as to follow the guide rail 4, and as shown in FIGS. 2 and 3, a first restricting portion 61 having elasticity, A second restricting portion 62.

  As shown in FIG. 3, the inner guide 6 has a space in which the inner cable 5 can slide in the inner guide 6 when the carrier plate 3 moves up and down by the first restricting portion 61 and the second restricting portion 62. A confinement structure S is formed. This confinement structure S is a structure formed so that the inner cable 5 arranged in the inner guide 6 does not come out of the inner guide 6. In this embodiment, as shown in FIG. The inner guide 6 is formed in a closed shape with no gap when viewed from the longitudinal direction.

  Further, as shown in FIGS. 1 and 6, the inner guide 6 extends in a direction substantially orthogonal to the axial direction of the guide rail 4 with the one end 81 fixed to the concave surface 41 side of the guide rail 4. The plate-like bracket 8 is detachably attached. As shown in FIGS. 4 and 6, the inner guide 6 is formed with an insertion groove 64 into which the other end portion 82 of the bracket 8 can be inserted. Further, as shown in FIGS. 2 and 5, the inner guide 6 is provided with a pair of locking pieces 65 extending in a direction orthogonal to the sliding direction of the inner cable 5. This locking piece 65 has elasticity, and its tip is locked in a hole 82a formed in the other end 82 of the bracket 8 as shown in FIG. For example, as shown in FIG. 6 and FIG. 7, the bracket 8 is formed to be bent so as to be provided with a step H, and since the carrier plate 3 is separated from the track when the carrier plate 3 moves up and down, the carrier plate 3 is raised and lowered. It does not interfere. As described above, the inner guide 6 is configured so that the locking piece 65 is locked to the hole 82a of the bracket 8 in a state where the other end 82 of the bracket 8 is inserted into the insertion groove 64. It is attached to the bracket 8 so that the position is at a height aligned with the convex surface 42 of the guide rail 4.

  As shown in FIG. 2, the first restricting portion 61 has a pair of restricting members 61 a that are spaced apart from each other in the axial direction of the guide rail 4. The restricting member 61a is made of, for example, a synthetic resin having elasticity. As shown in FIG. 3, the regulating member 61 a is formed as a claw member that protrudes in a direction substantially perpendicular to the sliding direction of the inner cable 5, and the inner cable 5 is closed by the inner guide 6. The inner cable 5 can be disposed in the confinement structure S by bending when being disposed in the structure S. After the inner cable 5 is disposed in the confinement structure S, the confinement structure S is formed again. It has elasticity that can return to the original position before bending. Further, the restricting member 61a has such elasticity that the inner cable 5 disposed in the confinement structure S is restrained from being bent with respect to the force acting in the direction in which the inner cable 5 tends to come out of the confinement structure S. Is formed.

  As shown in FIGS. 2 and 3, the second restricting portion 62 is disposed between the pair of restricting members 61a so as to face the extending direction of the restricting member 61a in the direction perpendicular to the longitudinal direction of the guide rail 4. ing. The second restricting portion 62 is formed so as to be substantially orthogonal to the sliding direction of the inner cable 5 and to protrude in the direction opposite to the distal end side of the restricting member 61a. As shown in FIG. 3, when viewed from the longitudinal direction of the guide rail 4, the position of the protruding tip of the second restricting portion 62 in the direction orthogonal to the longitudinal direction of the guide rail 4 is the tip of the restricting member 61a. It extends to the overlapping position. Further, the bottom surface of the second restricting portion 62 is provided so as to have substantially the same height as the top surface of the restricting member 61a. Therefore, when viewed from the longitudinal direction of the guide rail 4, the inner guide 6 is formed with a closed structure S without a gap, as shown in FIG. Moreover, as shown in FIG. 3, the front-end | tip of the 2nd control part 62 is formed in the taper shape. Therefore, it is easy to guide the inner cable 5 into the confinement structure S when the inner cable 5 is inserted into the confinement structure S.

  The inner guide 6 has a temporary placement portion 63 on which the inner cable 5 can be temporarily placed. The temporary placement portion 63 is a portion for temporarily placing the inner cable 5 when the inner cable 5 is inserted into the closed structure S. As shown in FIG. 2, the temporary placement portion 63 is provided between the pair of regulating members 61a. A pair is provided. The temporary placement portion 63 can temporarily place the inner cable 5 before applying the tension to place the inner cable 5 in the closed structure S, and the inner cable 5 moves to the regulating member 61a by the application of the tension. It is a possible part. The temporary placement portion 63 is provided so as to protrude in a direction orthogonal to the sliding direction of the inner cable 5 in FIG. 3, and the upper surface is formed to be substantially horizontal. The dimension in the depth direction orthogonal to the sliding direction of the inner cable 5 on the upper surface of the temporary placement portion 63 is set to be at least longer than the diameter of the inner cable 5 as shown in FIG. Can be placed stably. Further, the upper surface of the temporary placement portion 63 is set to have substantially the same height as the sliding surface 66 on which the inner cable 5 slides when the inner cable 5 is disposed in the confinement structure S. Yes. Note that the position of the upper surface of the temporary placement portion 63 is not limited to the above-described height, and may be set to a position that is at least lower than the upper surface of the restricting member 61 a and is higher than the sliding surface 66. It may be set to. In addition, in this embodiment, as shown in FIG. 2, the temporary placement part 63 has shown the example provided as a pair between the control members 61a, However, The number of the temporary placement parts 63 and the position provided are here. It is not limited, and when the inner cable 5 is inserted into the closed structure S, the inner cable 5 may be temporarily placed so that it can be easily inserted along the outer peripheral surface of the regulating member 61a. It ’s fine.

  The sliding surface 66 is a surface on which the inner cable 5 disposed in the confinement structure S slides, and is formed to be slightly curved in the sliding direction of the inner cable 5 as shown in FIG. . Thereby, since the inner cable 5 slides on the sliding surface 66 so as to follow the curved guide rail 4, the surface pressure can be lowered, so that the inner cable 5 can be easily slid. .

  Hereinafter, a method of inserting the inner cable 5 into the inner guide 6 will be described with reference to FIG. When the inner cable 5 is not disposed in the closed structure S of the inner guide 6, the pulley 7 provided at the upper end of the guide rail 4 and the lower end of the guide rail 4 are applied by the tension applied by the driving device 2. The drums 21 are arranged in a straight line so as to pass through the shortest distance between the drums 21 provided. When the inner cable 5 is inserted into the closed structure S of the inner guide 6 from this state, the inner cable 5 is separated from the straight cable routing route of the inner cable 5 by a device (not shown) or manually. Apply tension to. Here, as shown in FIG. 8A, the inner cable 5 is pulled toward the upper surface of the regulating member 61 a, and the inner cable 5 is temporarily placed on the upper surface of the temporary placement portion 63.

  And as shown to Fig.8 (a), it moves to the upper surface direction of the control member 61a along the outer peripheral surface of the control member 61a. At this time, tension is applied to the inner cable 5.

  Therefore, as shown in FIG. 8B, the inner cable 5 is moved by the tension applied to the inner cable 5, and the elastic regulating member 61a is pressed so that the tension of the inner cable 5 is reduced. The inner cable 5 is arranged in the closed structure S by bending downward. In addition, the tension | tensile_strength provided to this inner cable 5 should just be a tension | tensile_strength which can bend at least the control member 61a.

  When the inner cable 5 is disposed in the confinement structure S, as shown in FIG. 8C, the regulating member 61a that has been bent by the tension of the inner cable 5 is restored to the position before the bending, The confinement structure S is formed again. As described above, the regulation member 61 a is configured such that the inner cable 5 that is routed between both ends in the vertical direction of the guide rail 4 in a state in which tension is applied by the driving device 2 is routed along the guide rail 4. It is only necessary to be able to bend by the tension applied to the inner cable 5 when being disposed in the inner guide 6. Further, the restricting member 61a has such an elasticity that the inner cable 5 disposed in the confinement structure S is restrained from being bent by a force acting in a direction to escape from the confinement structure S. Since it is formed, it is possible to prevent the inner cable 5 from coming out of the closed structure S.

  In the inner guide 6 according to the present embodiment, the temporary placement portion 63 is provided. Therefore, when the inner cable 5 is inserted into the closed structure S, the inner cable 5 is temporarily placed in the temporary placement portion 63, By moving the cable 5 along the outer peripheral surface of the restricting member 61a, the cable 5 can be easily inserted into the confinement structure S. Further, by temporarily placing the inner cable 5 in the temporary placement portion 63, it is possible to prevent the inner cable 5 from entering under the inner guide 6 or the like. The inner cable 5 may be directly placed on the upper surface of the regulating member 61a without providing the temporary placement portion 63. Moreover, in the inner guide 6 of this embodiment, although the example which provided a pair of control member 61a is shown, it is not limited to this, The at least 1 control member 61a should just be provided.

  In the present embodiment, the window regulator 1 has been described as an example of the opening / closing body opening / closing device. However, the opening / closing body opening / closing device is not limited to the window regulator, and is provided along the guide rail 4 by the inner cable 5.
