  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIG. 12 shows a retractable assist grip G, which is attached and fixed from the vehicle compartment side to a vehicle body panel as a fixed body constituting a part of the vehicle compartment side wall of the vehicle, for example. The assist grip G includes a resin grip body 1 made of, for example, PP (polypropylene) and a pair of first and second mounting seats 3, 5 made of, for example, POM (polyacetal). The grip body 1 has a long bar shape, and is arranged so that the longitudinal direction thereof substantially coincides with the longitudinal direction of the vehicle body. The grip body 1 has both ends in the longitudinal direction curved in the same direction to form a substantially U shape, and the both ends are the first and second legs 1a and 1b, respectively.

  The grip body 1 has a pair of first and second leg portions 1a and 1b rotatably attached to a pair of first and second mounting seats 3 and 5 by support shafts 7 and 9, respectively. Due to the pivotal support structure of both the leg portions 1a and 1b, the grip body 1 rotates between the use position and the storage position, and when in the use position, the intermediate portion of the grip body 1 protrudes toward the interior of the vehicle and projects horizontally. On the other hand, when in the retracted position, the grip body 1 is rotated approximately 90 ° upward from the use position and is in a state along the vehicle body panel on the side wall of the passenger compartment.

  In the first and second leg portions 1a and 1b of the grip body 1, a substantially semi-elliptical recess cut out in a substantially rectangular cross section is formed on the vehicle body panel facing surface when the grip body 1 is in the retracted position. And a part of the first and second mounting seats 3 and 5 are accommodated in each accommodating part 11 at the storage position of the grip body 1 (see FIG. 10).

  The support shaft 7 that pivotally supports the first leg 1a (the left side in FIG. 12) of the grip body 1 on the first mounting seat 3 is urged to rotate the grip body 1 from the use position to the storage position. A torsion coil spring 13 is fitted as a means, and a support shaft 9 for viewing the second leg 1b (on the right side in FIG. 12) on the second mounting seat 5 gives resistance to the rotation of the grip body 1. For example, a damper device 15 filled with a viscous fluid having a high viscosity (preferably 100000 cps or more) such as silicon is mounted as a damper means for slowing the rotating operation.

  The first and second mounting seats 3 and 5 are provided with a mounting seat body 17 having an insertion hole 17a penetrating the front and back, and the periphery of the insertion hole 17a on the back surface of the mounting seat body 17 is also shown in FIGS. As shown, a pair of flexible locking pieces 19 each having a locking claw 19a at the tip thereof are provided so as to protrude from each other, and the cap 21 is inserted in a state where both the locking pieces 19 are inserted into the locking holes of the vehicle body panel. A lock pin 23 that protrudes integrally from the insertion hole 17a is inserted from the front side into the insertion hole 17a so that both the locking pieces 19 are pushed outward outward from each other, and the insertion hole 17a is covered with the cap 21 by The locking claws 19a of both locking pieces 19 are locked to the periphery of the locking hole of the vehicle body panel, and the first and second mounting seats 3, 5 are fixedly mounted on the vehicle body panel.

  The assist grip G configured as described above includes the grip body 1, the first mounting seat 3, the second mounting seat 5, the torsion coil spring 13, and the damper device 15, but the cap 21 is not yet assembled. At a stage, it is carried into a damper function inspection device 25 as shown in FIG. 1 provided in the damper function inspection process, and the quality of the damper function is determined.

  The damper function inspection device 25 includes a vertically long rectangular parallelepiped casing 27. Below the casing 27, two first elevating cylinders 29 are supported by a gantry 31 with a distance from each other, and are vertically moved up and down. A horizontal plate 33 is bridged at the tip of the piston rod 29a (see FIG. 4) of each first elevating cylinder 29, and two second elevating cylinders 35 are mounted on the horizontal plate 33 to the housing 27. It arrange | positions so that raising / lowering is possible via the support member 37 at intervals, so that it may incline and rise toward the back toward the inner part. A temporary receiving tool 39 for temporarily receiving the assist grip G is attached to the tip of the piston rod 35a (see FIG. 5) of each second elevating cylinder 35.

  On the other hand, above the inside of the casing 27, a set wall 41 serving as an inspection position is disposed so as to incline forward toward the front of the casing 27. The inclination angle of the set wall 41 is set to an angle that assumes an actual attachment state of the assist grip G to the vehicle body panel. A pair of insertion holes 43 (see FIGS. 6 and 10) are formed in the set wall 41 in accordance with the distance between the first and second legs 1a and 1b of the assist grip G. The insertion holes 43 have holding means. The holding pin 45 is arranged so as to be able to advance and retreat by operating means (not shown). The size, pitch, parallelism, and the like of the pair of insertion holes 43 are also set assuming actual mounting states of the first and second mounting seats 3 and 5 with respect to the vehicle body panel. Then, the assist grip G carried in by the first robot 47 is provisionally received by the temporary receiver 39 (see FIGS. 2 and 3), and the first elevating cylinder 29 is extended (see FIG. 4). The elevating cylinder 35 is extended (see FIG. 5), whereby the locking pieces 19 of the first and second mounting seats 3, 5 are inserted into the insertion holes 43 of the set wall 41, and in this state, the holding The pin 45 is advanced and its tip is inserted between the pair of locking pieces 19 and both locking pieces 19 are pushed outward so as to be separated from each other, and each locking claw 19 a is locked to the periphery of the insertion hole 43. Thus, the assist grip G is received from the temporary holder 39 and is held on the set wall (inspection position) 41 in a posture assuming an actual attachment state (see FIGS. 6 and 10).

  A gear 49 that meshes with a rack (not shown) is disposed on the set wall 41 between the pair of holding pins 45, and a lever 53 is integrally connected to a rotating shaft 51 of the gear 49 so that the rack is connected to a drive cylinder. By moving the gear 49 counterclockwise in FIG. 1 by moving it (not shown), the lever 53 is pivoted downward with the pivot shaft 51 as a fulcrum, and the grip body 1 is moved from the retracted position. It is designed to rotate to the use position. Therefore, the gear 49, the lever 53, the rack and the drive cylinder constitute a rotating device 55 as a rotating means.

  On both side walls of the casing 27, a first infrared sensor 57 as a first detecting means for detecting that the grip body 1 is in the retracted position, and a first infrared sensor 57 for detecting that the grip body 1 is in the use position. 2 A second infrared sensor 59 as a detection means is arranged at a distance from the top and the bottom, and the grip body 1 is in a use position or is stored by blocking the infrared rays projected from the sensors 57 and 59 by the grip body 1. It detects the position. The detection signals of the first and second infrared sensors 57 and 59 are input to the CPU 61 as a determination means (see FIG. 1), and the normal grip body 1 is rotated from the use position to the storage position. The return time until reaching the position is preset and stored, and the grip body 1 of the assist grip G used for the inspection is rotated from the use position in FIG. 7 until it reaches the retracted position through the state in FIG. The return time is measured based on the detection signals of the first and second infrared sensors 57 and 59, and this measurement time is compared with the set time to determine whether the damper function of the assist grip G is good or bad. . The return time from the normal grip body 1 rotated from the use position to the storage position after the set time is set in the range of 0.5 to 3.5 seconds. This is because if the return time is shorter than 0.5 seconds, the damper effect is not subjectively recognized, and a hitting sound is easily generated when the grip body 1 rotates from the use position and stops at the retracted position. It is. On the other hand, if the return time is longer than 3.5 seconds, the grip body 1 may subjectively feel that it has not returned to the storage position.

  Next, a procedure for determining the quality of the damper function of the assist grip G by the damper function inspection device 25 will be described with reference to the process diagrams of FIGS. 2 to 10 and the flowchart of FIG.

  First, as shown in FIG. 2, the first robot 47 holds the assist grip G in which the grip body 1, the first mounting seat 3, the second mounting seat 5, the torsion coil spring 13 and the damper device 15 are assembled. It carries in to the damper function test | inspection apparatus 25, and as shown in FIG. 3, it mounts on the temporary holder 39 in the state which the latching piece 19 faces upwards, and temporarily receives with the temporary holder 39 (step S1). The cap 21 is not yet assembled to the assist grip G at this stage.

  Next, as shown in FIG. 4, the two first lifting cylinders 29 are simultaneously extended to move the assist grip G closer to the set wall 41, and then, as shown in FIG. The cylinder 35 is simultaneously extended to bring the first and second mounting seats 3 and 5 of the assist grip G into contact with the set wall 41, and the first and second mounting seats 3 and 5 are locked as shown in FIG. The pieces 19 are inserted into the two insertion holes 43, respectively. Thereafter, the holding pin 45 is advanced from the state shown in FIG. 6 in each insertion hole 43 and inserted between the pair of locking pieces 19, and both locking pieces 19 are pushed outward so as to be separated from each other. And the assist grip G is held on the set wall (inspection position) 41 in a posture assuming an actual attachment state (step S2).

  Thereafter, as shown in FIG. 7, after the first and second elevating cylinders 29 and 35 are both contracted and retracted downward, the rack of the rotating device 55 is moved by the drive cylinder to move the gear 49 to the position shown in FIG. Then, the lever 53 is rotated downward with the rotation shaft 51 as a fulcrum, and the grip body 1 is pushed down to be positioned at the use position. In this state, the grip body 1 blocks the infrared rays from the second infrared sensor 59 and the second infrared sensor 59 detects that the grip body 1 is in the use position, and this detection signal is input to the CPU 61. From this state, when the rack is moved in the opposite direction by the drive cylinder, the gear 49 is rotated clockwise in FIG. 7, and the lever 53 is rotated upward with the rotation shaft 51 as a fulcrum. The posture is along the set wall 41, and the grip body 1 is released from the pressing force of the lever 53. Then, the grip body 1 is rotated upward with the support shafts 7 and 9 as fulcrums while being rotated slowly by the damper device 15, and is rotated to the retracted position through the state of FIG. 8 (step S3). In this state, the infrared ray from the first infrared sensor 57 is blocked by the grip body 1 and the first infrared sensor 57 detects that the grip body 1 is in the storage position, and this detection signal is input to the CPU 61.

  The CPU 61 measures the return time until the grip body 1 rotates from the use position to the storage position based on the detection signals of the first and second infrared sensors 57 and 59, and compares this measurement time with the set time. Then, the quality of the damper function of the assist grip G is determined (step S4). If the determination is YES, it is considered that the damper function is normal, the rack of the rotation device 55 is moved by the drive cylinder, the gear 49 is rotated counterclockwise in FIG. 9, and the lever 53 is rotated. The grip body 1 is pushed downward by turning 51 downward with the fulcrum as a fulcrum, and is rotated again to the use position (step S5). In this state, the cap 21 is gripped by the second robot 63, and the lock pin 23 is inserted into the insertion holes 17a of the first and second mounting seats 3, 5 from the front side as shown in FIG. The grip body 1 is temporarily fixed by being brought into contact with the accommodating portions 11 of the first and second leg portions 1a and 1b, and held at an intermediate position between the use position and the storage position. The holding state is shown in FIG. 10 (step S6).

  Thereafter, the first elevating cylinder 29 is extended to bring the temporary holder 39 closer to the assist grip G. In this state, the holding pin 45 is retracted and removed from between the locking pieces 19, and then an unillustrated push pin The assist grip G is removed from the set wall (inspection position) 41 (step S7), held by the first robot 47, and carried out to the non-defective product storage area (step S8).

  On the other hand, if the determination in step S4 is NO, the damper function is regarded as abnormal, the cap 21 is not temporarily fixed, the first elevating cylinder 29 is extended, and the temporary holder 39 is brought closer to the assist grip G. In this state, the holding pin 45 is retracted and removed from between the locking pieces 19, and then the push pin is advanced to remove the assist grip G from the set wall (inspection position) 41 (step S9). It is gripped by 47 and carried out to the defective product storage area (step S10).

  As described above, the time taken for the assist grip G to be held on the set wall (inspection position) 41 in a posture assuming an actual mounting state and the grip body 1 to be rotated from the use position to the storage position is set time. Since it is determined whether or not the damper function is normal, the defective product is removed from the assembly line before the assembly of the assist grip G is completed, and only the non-defective product having the normal damper function is processed next. Can be stably supplied, and a defective product can be replaced with a non-defective product by being actually attached to the vehicle body or the like, so that assembly work can be performed efficiently.

  The present invention relates to a method for assembling a retractable assist grip having a damper function so that when the grip body is rotated from the use position to the retracted position, the rotating operation is slowed down, and used in the assembling process. It is useful as a damper function inspection device.
