As shown in FIGS. 7A to 7C, the curved grooves 62 are used to rotate the rotating housing 10 so that the upper and lower shafts 18 and 19 of the rotating housing 10 are positioned at the forefront position. Is a substantially arc shape having a circle as a center. The central angle and the radius of curvature of the curved groove 62 are determined by the depth and width of the storage space, the shape of the storage section 16 of the rotary storage body 10 in plan view, and the like when the rotary storage body 10 is rotated. 2 may be set as appropriate so as not to touch the 2. The central angle of the curved groove 62 may be, for example, about 60 ° to 120 °. Further, the radius of curvature of the curved groove 62 may be increased, for example, as the ratio of the width dimension to the depth dimension of the storage space (rotary storage body 10) increases.

The straight groove portions 63 are provided so as to be continuous with both end portions in the frontage direction of the curved groove portion 62. These straight groove portions 63 are provided so as to be located substantially at the center in the depth direction of the storage space of the box body 2 and to extend in the frontage direction. The boundary between the straight groove portions 63 and the curved groove portion 62 is curved so that the first roller 54 and the second roller 55 move smoothly.
The side guide bodies 50 are positioned in the linear grooves 63 on both sides in the state where the rotary storage body 10 is stored and in the initial and final states when the rotary storage body 10 is rotated (FIGS. 3 and 7). (D)).
As shown in FIGS. 3 and 7, the rotating storage device 1 having the above-described configuration is configured such that the rotating storage body 10 is rotated and turned back and forth as described below.

  As shown in FIG. 3 and FIG. 7A, in an initial state when rotating the rotary storage body 10 from a state in which the rotary storage body 10 is stored, the side guide body 50 is provided with one of the curved guide grooves 61. The upper and lower central guides 20 and 30 move forward while moving toward the center in the frontage direction along the straight groove 63. Then, as shown in FIGS. 7A to 7C, when the side guide body 50 reaches the curved groove 62 of the curved guide groove 61, the upper guide shaft 18 and the lower guide shaft 19 are rotated about the pivot. The side guide body 50 moves along the curved groove 62 so as to draw an arc so that the storage body 10 rotates. Then, as shown in FIGS. 7 (c) and 7 (d), when the rotation storage body 10 is rotated in the final state, that is, when the side guide body 50 reaches the other linear groove 63, the side guide body is rotated. The upper and lower central guides 20 and 30 move rearward while 50 moves outward along the frontage along the other straight groove 63. As a result, the rotary housing 10 is rotated by 180 ° around the upper and lower shafts 18 and 19, and the front and rear sides are inverted. As described above, the rotary storage device 1 rotates the rotary storage body 10 around the shafts 18 and 19 while moving the upper and lower shafts 18 and 19 of the rotary storage body 10 in the front-rear direction. The front and rear can be switched (switched).

The guide device 9 and the rotary storage device 1 including the same according to the present embodiment can smoothly guide the movement of the rotary storage body 10 to be guided by having the above-described configuration.
That is, the first roller 54 is urged so as to contact the groove wall (first groove wall) 65 on one side in the groove width direction of the guide groove (curved guide groove) 61, and the second roller 55 is turned on the other side in the groove width direction. An urging mechanism 53 for urging the groove wall (the second groove wall) 66 so as to contact the groove wall 66 is provided. Therefore, the first roller 54 of the side guide body 50 as a guided member attached to the rotary housing 10 is brought into contact with the first groove wall 65 on one side in the groove width direction to roll, and the second roller 55 is moved. The rolling can be performed by contacting the second groove wall 66 on the other side in the groove width direction. As a result, when the rotary storage body 10 is moved, the rattling generated between the groove walls 65, 66 on both sides of the curved guide groove 61 of the rail (curved rail) 60 and the side guide body 50, and an irregularity caused by the rattling occur. Generation of sound can be suppressed, and the side guide body 50 can be moved smoothly.

  Also, in the present embodiment, the groove walls 65 and 66 on both sides in the groove width direction of the curved guide groove 61 are inclined so that the groove width dimension of the curved guide groove 61 decreases toward the groove bottom 64 or the groove opening. The inclined surface is provided. Further, the urging mechanism 53 is configured to urge the first roller 54 and the second roller 55 in a direction along the axis (common roller axis) 52 toward the side where the groove width dimension of the curved guide groove 61 becomes smaller. ing. Therefore, the first roller 54 can be pressed against the inclined surface of the first groove wall 65 on one side in the groove width direction in the direction along the common roller axis 52 direction. Further, the second roller 55 can be pressed against the inclined surface of the second groove wall 66 on the other side in the groove width direction in the direction along the common roller axis 52 direction. Thereby, for example, the load on the common roller shaft 52 in the groove width direction can be effectively reduced as compared with the case where one of the groove walls (65) is formed in a plane perpendicular to the groove bottom 64. . Further, the first roller 54 and the second roller 55 can be smoothly rotated along the respective groove walls 65 and 66 with which the respective rollers abut. Further, the biasing direction is a direction inclined with respect to each of the groove walls 65 and 66, and is a direction substantially along the common roller shaft 52 direction of each of the rollers 54 and 55. Thereby, for example, compared to a mechanism provided with an urging mechanism for urging each of the rollers 54 and 55 in the groove width direction, the deflection of the rollers 54 and 55 with respect to the curved guide groove 61 in the groove width direction is more effectively achieved. Can be suppressed. Further, in the present embodiment, since the outer peripheral surfaces of the rollers 54 and 55 are configured to be in point contact with the inclined surfaces of the groove walls 65 and 66, the outer peripheral surfaces are linearly contacted. The rollers 54 and 55 can be rotated more smoothly than those in contact with each other.

  In the present embodiment, the first roller 54 and the second roller 55 are provided coaxially at intervals in the direction of the common roller shaft 52. Therefore, the structure can be simplified as compared with the case where the first roller 54 and the second roller 55 are provided in parallel in the groove width direction or the groove longitudinal direction. Further, the first roller 54 disposed on the side where the groove width dimension of the curved guide groove 61 becomes smaller has a smaller diameter than the second roller 55, and the curved guide groove 61 is formed to have a groove width with which the first roller 54 abuts. The second roller 55 is formed so as not to contact the first groove wall 65 on one side in the direction. Accordingly, while the first roller 54 and the second roller 55 are provided coaxially, the first roller 54 having a small diameter is brought into contact with the first groove wall 65, and the second roller 55 having a large diameter is connected to the first groove wall. The second groove wall 66 can be contacted without contacting the second groove wall 65.

The parts 7 and 8 are provided. Therefore, it is possible to efficiently store the object to be stored in the rotating storage body 10 or to easily remove the stored object by rotating the rotating storage body 10. In addition, the rotating housing 10 can be rotated around the axes 18 and 19 along the vertical direction while moving the rotating housing 10 in the front-back direction with respect to the box 2. Thereby, when rotating the rotating container 10, it is possible to prevent the rotating container 10 from projecting rearward from the state in which the rotating container 10 is stored in the box 2. In other words, it is possible to reduce the space required for rotating the rotating housing 10 that is required on the back side of the rotating housing 10 housed in the box 2, and to secure the depth dimension of the storage unit of the rotating housing 10. However, the depth dimension of the box 2 can be efficiently reduced. Further, since the movement of the rotary housing 10 can be guided by the guide device 9 according to the present embodiment, as described above, rattling and generation of abnormal noise can be suppressed.

In the present embodiment, the wall height of the first groove wall 65 is set smaller than the wall height of the second groove wall 66 so that the second roller 55 does not contact the first groove wall 65. Although an example is shown, the present invention is not limited to such an embodiment. For example, the first groove wall 65 may be provided with a stepped or curved wall that avoids the second roller 55.
In the present embodiment, an example is shown in which the first roller 54 and the second roller 55 are provided coaxially and one of the first rollers 54 has a smaller diameter than the second roller 55. It is not limited to the embodiment. For example, a configuration in which a roller shaft that individually and rotatably holds the first roller 54 and the second roller 55 may be provided. In this case, the configuration may be such that the roller shaft of the first roller 54 and the roller shaft of the second roller 55 are provided at different positions in the groove width direction or the groove longitudinal direction. In this case, the first roller 54 and the second roller 55 may have substantially the same diameter or the like. In this case, the urging mechanism 53 may be provided on each of the roller shaft of the first roller 54 and the roller shaft of the second roller 55. In addition, the urging mechanism 53 having various configurations may be employed. Is possible.

Further, in the present embodiment, the groove width dimension of the groove walls 65, 66 on both sides of the curved guide groove 61 of the curved rail 60 is increased toward the groove bottom 64 side in the vertical direction (the vertical direction outer side of the box body 2). Although an example in which a small inclined surface is provided is shown, the configuration may be reversed. In other words, the groove walls 65 and 66 on both sides of the curved guide groove 61 of the curved rail 60 are inclined such that the groove width decreases toward the center in the vertical direction (the center in the vertical direction of the box body 2) which is the groove opening side. A configuration having a surface may be adopted. In this case, the rollers 54 and 55, the roller shaft 52, the urging mechanism 53, and the like may be appropriately deformed as needed.
