  As shown in FIG. 1, a handle 128 is provided at the front right end portion of the left sliding door 51 and the front left end portion of the right sliding door 52.

  Next, the operation and the like of the storage device 1 will be described.

  As shown in FIGS. 2, 6 and 14, when the front opening 2 of the storage device body 4 is fully closed, the sliding doors 51, 52 are positioned in the closed position in a posture along the left-right direction and are in a left-right flat state. It has become.

  In this state, the left guide body 57 and the right guide body 58 are both positioned parallel to each other along the front-rear direction, and the rear shaft 82 of the left guide body 57 is positioned at the left end of the left elongated hole portion 66. The rear shaft 92 of the right guide 58 is located at the left end of the right long hole 68. Further, the horizontal rollers 113 and 114 of the sliding door mounting body 101 are located at the rear ends of the arcuate guide portions 29 and 31 of the upper guide rails 26 and 27. Further, with respect to the left and right tuning mechanisms 55, as shown in FIGS. 18 to 20, etc., the upper and lower rotating bodies 136 are brought into a desired approach by engaging a part of the spherical positioning body 152 and the approach state recess 141. The guided members 147 of the upper and lower guided bodies 137 are engaged with the guide rails 36 and 37.

  For example, when the left half of the front opening 2 of the storage device body 4 is opened, the operator holds the handle 128 and pulls the left sliding door 51 forward against the urging force of the tension coil spring 121.

  Then, as shown in FIGS. 3, 7, and 15, the left sliding door 51 rotates while moving forward to change the posture from the posture along the left-right direction to the inclined posture slightly inclined with respect to the left-right direction. .

  That is, when the horizontal rollers 113 and 114 of the sliding door mounting body 101 of the upper traveling unit 53 travel along the arcuate guide portions 29 and 31 of the upper guide rails 26 and 27, the sliding door mounting bodies 101 and 126 become the left sliding door 51. And rotate while moving forward.

  At this time, with respect to the traveling body 56 in the stopped state, the left guide body 57 rotates rightward so that the rear shaft 82 moves along the left long hole portion 66 about the front shaft 59, and the sliding door mounting body The left roller 102 of 101 travels forward along the guide groove 83 of the rotating left guide body 57, and the right guide body 58 is rearward about the front shaft 60 with respect to the travel body 56 in a stopped state. The side shaft 92 rotates rightward so as to move along the right long hole portion 68, and the right roller 103 of the sliding door mounting body 101 moves forward along the guide groove portion 93 of the rotating right guide body 58. Run. Therefore, the sliding door mounting body 101 smoothly travels forward along the left and right guide bodies 57 and 58 due to the rotation of the left and right rollers 102 and 103 in spite of receiving the weight of the left sliding door 51. Smooth movement of the mounting body 101 is obtained.

  At this time, the upper and lower rotating bodies 136 of the tuning mechanism 55 rotate about the shaft body 131 with respect to the mounting body 132, and a part of the positioning body 152 is in an approaching state against the urging force of the compression coil spring 153. It slips out of the concave portion 141 for use.

  Subsequently, the operator moves the left sliding door 51 to the right while holding the handle 128. Then, as shown in FIGS. 4, 8, and 16, the left sliding door 51 rotates while moving forward and returns to the posture along the left-right direction, and then moves rightward to the open position. As a result, the sliding doors 51 and 52 are in a sliding state where they overlap each other in the front-rear direction, and the left half of the front opening 2 opens.

  That is, the horizontal rollers 113 and 114 of the sliding door mounting body 101 travel along the arcuate guide portions 29 and 31 and the linear guide portions 28 and 30 of the upper guide rails 26 and 27, and the traveling body 56 is guided by the guide rails 21 and 22 And the guided member 147 of the synchronization mechanism 55 travels along the guide rails 36 and 37, so that the sliding door mounting bodies 101 and 126 rotate together with the left sliding door 51 while moving forward. Then move to the right.

  At this time, the left guide body 57 is rotated leftward with respect to the traveling body 56 that is traveling, and the left roller 102 of the sliding door mounting body 101 is rotated to the left. The vehicle slides forward along the guide groove 83 of the guide body 57 and rotates to the left until the right guide body 58 is in a state along the original front-rear direction with respect to the traveling body 56 that is running. The right roller 103 of the mounting body 101 travels forward along the guide groove portion 93 of the rotating right guide body 58. Therefore, the sliding door mounting body 101 smoothly travels forward along the left and right guide bodies 57 and 58 due to the rotation of the left and right rollers 102 and 103 in spite of receiving the weight of the left sliding door 51. Smooth movement of the mounting body 101 is obtained.

  Further, the upper end portion and the lower end portion of the left sliding door 51 are synchronized by the synchronization mechanism 55, and the upper end portion and the lower end portion of the left sliding door 51 perform the same movement. When the left sliding door 51 moves to the right side and is positioned at the open position, the upper and lower rotating bodies 136 are separated from a part of the spherical positioning body 152 as shown in FIGS. It is positioned in a desired separated state by engagement with the recess 142.

  When closing the left half of the front opening 2, the left sliding door 51 is operated to perform a closing operation. At the end of the closing operation, the sliding door mounting body 101 is similar to the above-described initial opening operation. The left and right rollers 102 and 103 rotate smoothly along the left and right guide bodies 57 and 58, so that the sliding door mounting body 101 moves smoothly. In addition, what is necessary is just to operate the right sliding door 52, when opening and closing the right half part of the front opening part 2. FIG.

  According to such a storage device 1, the left and right synchronization mechanisms 55 are in an approaching state close to the attachment body 132 when the sliding doors 51 and 52 are located at the closed position, and the sliding doors 51 and 52 are located at the open position. The upper and lower rotating bodies 136 that are separated from the mounting body 132 in the state, the upper and lower guided bodies 137 that run along the corresponding guide rails 36 and 37 provided on each rotating body 136, and the rotating body 136 are approached. Since the upper and lower torsion coil springs 138 are energized so as to be in a state, the upper and lower ends of the sliding doors 51 and 52 can be synchronized by the synchronization mechanism 55 when the sliding doors 51 and 52 are operated. 51 and 52 can be prevented from fluttering, so that the operability of the sliding doors 51 and 52 can be improved, and the sliding doors 51 and 52 can be appropriately opened to the open position.

  Further, when the sliding doors 51 and 52 are in the closed position by the positioning means 151 of the synchronization mechanism 55, the rotating body 136 can be positioned in the approaching state, and when the sliding doors 51 and 52 are in the open position, the rotating body 136 is separated. The sliding doors 51 and 52 can be effectively prevented from fluttering.

  Further, since the guided body 137 of the synchronization mechanism 55 includes the elevating member 146, the guided member 147, and the compression coil spring 148, for example, when the sliding doors 51, 52 are assembled to the storage device body, the sliding doors 51, 52 The tuning mechanism 55 attached to the upper and lower guide rails 36 and 37 can be easily mounted between the upper and lower guide rails.

  Further, since the shaft body 131 of the tuning mechanism 55 is fixedly attached to the rear surfaces of the sliding doors 51 and 52 via the attachment body 132 and the support body 133, an excessive torsional moment does not act on the shaft body 131. In addition, torsional deformation of the shaft body 131 can be prevented.

  Furthermore, no space is required between the lower surface of the lower plate 12 of the storage device main body 4 and the mounting surface such as the floor surface, the storage space 3 can be enlarged, and the storage device main body 4 is suspended and installed. The metal plate is not exposed on the lower surface of the lower plate 12, so that it looks good.

  On the other hand, a left guide body 57 and a right guide body 58 that are rotatably attached to the traveling body 56 in the left-right direction, and a left roller 102 and a right guide body 58 that travel in the front-rear direction along the left guide body 57. Since the sliding door mounting body 101 has the right roller 103 that travels in the front-rear direction, the sliding door mounting body 101 can be smoothly moved at the initial opening operation time and at the end of the closing operation of the sliding doors 51 and 52. Thus, the operability of the sliding doors 51 and 52 can be improved.

  The left roller 102 of the sliding door mounting body 101 is rotatably fitted in a guide groove 83 having a substantially C-shaped cross section of the left guide 57 and travels in the front-rear direction along the guide groove 83 while rotating. Since the right roller 103 of the mounting body 101 is configured to run in the front-rear direction along the guide groove 93 while being rotatably fitted in the guide groove 93 having a substantially C-shaped cross section of the right guide 58, The left roller 102 and the right roller 103 do not slip outward from the guide groove portions 83 and 93, and the sliding movement of the sliding door mounting body 101 can be obtained more smoothly by the rotation of the left roller 102 and the right roller 103. it can.

  In addition, although the said embodiment demonstrated the structure provided with the left-right paired sliding door 51 and the sliding door 52, the structure provided with one sliding door or three or more sliding doors etc. may be sufficient, for example.

  Further, the arcuate guide portion 29 of the upper front guide rail 26 may have a larger radius of curvature than the arcuate guide portion 31 of the upper rear guide rail 27, for example, as shown in FIG. Specifically, the radius of curvature of the arcuate guide portion 29 is preferably 5 to 7.5 times the radius of curvature of the arcuate guide portion 31.

  Furthermore, the guide rails 26 and 27 do not have an arcuate guide portion, for example, a linear guide portion that is longitudinal in the left-right direction, and a slightly longitudinal shape in the front-rear direction that is connected to both ends in the left-right direction of the linear guide portion. The structure which has a front-back guide part may be sufficient. In this configuration, the sliding doors 51 and 52 do not have an inclined posture that is slightly inclined with respect to the left-right direction, but always perform an opening operation and a closing operation in a posture along the left-right direction.

  The tuning mechanism 55 includes, for example, a mounting body 132 rotatably provided at both ends in the vertical direction of the shaft body 131, and the shaft body 131 around the shaft body 131 at both ends in the vertical direction of the shaft body 131. The structure etc. which have the rotation body 136 provided so that rotation was possible, and the to-be-guided body 137 provided in each rotation body 136 may be sufficient.

  Further, for example, the handle 128 held by the operator may be provided at the front left end portion of the left sliding door 51 and the front right end portion of the right sliding door 52. For example, a concave handle portion is formed on the front surface of the sliding doors 51 and 52. A configuration or the like may be used.

  Further, for example, as shown in FIGS. 25A and 25B, at the end of the closing operation of the sliding doors 51 and 52, the closing operation speed of the sliding doors 51 and 52 is gradually increased in cooperation with the buffer means 122 of the upper traveling unit 53.
