Description

  The present invention relates to a storage case that can move a storage space in a rotatable manner.

  Multi-stage storage cases with multi-stage drawer containers are used for clothing, daily necessities, ornaments, etc. (clothing, etc.), and the basic configuration is, for example, a combination of a resin container and a resin frame A combination of a resin container and a member.

  In a multi-stage storage case for storing an arbitrary number of container bodies in a drawer shape, a protrusion is provided around the top surface of the top plate, and a connecting recess is formed at an appropriate position on the upper surface of the protrusion, and facing in the recess. A wall is provided with an elastic force that is independent of the wall, provided with a holding part with a locking projection, and connected to the bottom part of the case frame body at a position corresponding to the connecting part and into the connecting part. It is known that a protrusion is provided and a locking portion that is pushed below the locking protrusion is provided (see, for example, Patent Document 1).

  Further, in the drawer container, the drawer is composed of a frame having a seat and a space where the drawer is opened so as to be detachable from a plurality of sides, a guide protrusion is formed on the seat in four directions, and a rear portion of the bottom of the drawer It is known that ribs are provided on the left and right parts, and the ribs on the left and right parts slide only in the front-rear direction of the drawer according to the guide protrusions while the rear ribs are located inside the guide protrusions (for example, , See Patent Document 2).

Utility Model Registration No. 3066410 No. 6-14581

  (1) In a known multistage storage case such as Patent Document 1, when the depth of the storage case is long, for example, it takes time to take out clothes and the like stored in the back of the storage case. For example, it is necessary to pull out the drawer portion of the storage case to the front and take out clothes and the like stored in the back. Moreover, it takes time and effort to take out clothes and the like stored in the back, such as once taking out the clothes on the front side of the storage case from the storage case. Further, when clothes or the like in the back of the storage case are taken out, it takes time and effort for the storage work each time, for example, by moving other clothes or the like to a storage space that is vacant in the back. Therefore, there was a trouble in taking out.

  (2) Also, it is difficult for the user to check which clothing or the like is stored as it is stored from the front to the middle and further to the back. For this reason, the user feels inconvenience in selecting the items to be stored from the storage case due to storage circumstances such as when clothes are rushed and clothes are stored in front of the storage case. In addition, in order to pull out the desired clothing or the like in front of the storage case, the organized clothing or the like may be forcibly pulled out and the clothing or the like stored by being folded may be disturbed.

(3) On the other hand, in a known technique such as Patent Document 2, since it is a drawer container comprising a drawer and a frame body having a seat and a space where the drawer is removably opened from a plurality of sides, the drawer can be pulled out from all directions. It is assumed that sufficient space is secured. For this reason, when the space where the drawer container is deferred is a space where the drawer cannot be pulled out in any of the front, left and right sides, and the back direction, it cannot be deferred in a limited space. In addition, even when it is left stationary, when it becomes necessary to pull out in that direction, the entire drawer container must be moved to a space where it can be pulled out in that direction, and work such as storing or taking out stored items has to be performed. .
The problem to be solved by the present invention is to provide a storage case in which a storage space can be moved in a rotatable manner so that stored items can be easily taken in and out.

  In order to solve the above-described problems, a storage case according to the present invention is a storage case that can be stacked in an upper and lower stage as a configuration having a plurality of stages, and that stores an object to be retracted. The storage case is formed in a hollow cylindrical shape having an opening at the top, and includes a middle case rotating portion that forms a storage space for storing the storage object, and a rod-shaped shaft in a plate-like and plate-like vertical direction. An intermediate case that is formed and disposed below the intermediate case rotation part and has an intermediate case bottom that rotatably supports the intermediate case rotation part with the shaft as a rotation center; The top case and the bottom plate, and an outer case that has a side wall that covers the periphery so that a drawer direction side is opened between the top plate and the bottom plate, and that accommodates the middle case so that the middle case can be pulled out freely. When the middle case accommodated in the outer case is pulled out to a position where at least a part of the storage space of the portion is visible from the side of the drawer direction where the side wall is opened, the middle case bottom is Serial storage space, characterized in that the rotatably supporting said in case the rotating part so as to circulate.

  According to the storage case according to the present invention, the storage space can be moved in a rotatable manner so that stored items can be easily taken in and out.

  (1) Thereby, since each storage case can circulate through the storage space and move freely, the stored items stored in front of the drawer can be easily moved. Moreover, the empty storage space can be easily moved to the front side. Thereby, the convenience in a user's storage work improves.

  (2) Since the storage case can stack a plurality of stages in the vertical direction, the number of stacking stages can be selected according to the installation space in the height direction of the installation location. Thereby, the installation space with restrictions in the height direction, such as a closet, a closet, a kitchen storage, etc., can be utilized effectively and without impairing convenience.

Further, as will be described later, the support column 14 has a convex locking portion 141 (shown in FIG. 6) and a concave locking portion 142 (shown in FIG. 7) of the storage case 1a positioned at the other stage (upper stage or lower stage). The support 14 can be fitted.

  6A is a plan view of the column 14 shown in FIG. 4, and FIG. 6B is a side view of the column 14 shown in FIG. 7A is a bottom view of the support column 14 shown in FIG. 4, and FIG. 7B is a vertical cross-sectional view taken along line XX in FIG. 7A.

  As shown in FIGS. 6 (A) and 6 (B), the support 14 is formed with a convex locking portion 141 protruding in a convex shape at one end (upper surface side) in the longitudinal direction. Further, as shown in FIGS. 7A and 7B, the column 14 is provided with a concave engaging portion 142 having a concave groove provided on the other end (bottom surface side) in the longitudinal direction.

  The convex locking part 141 can be fitted into the concave locking part 142 of the storage case 1a located in the upper stage. The concave locking part 142 can be fitted into the convex locking part 141 of the storage case 1a located in the lower stage. Further, the concave locking portion 142 may be configured not only to fit into the convex locking portion 141 but also to be used as a screw hole or a mounting hole of an accessory such as a caster or to share a part. In addition, the convex locking part 111a described above has a structure similar to the convex locking part 141, and the concave locking part 122a described above has a structure similar to the concave locking part 142.

  In the storage case 1a of the present embodiment, the outer case side wall 13a and the support column 14 in the outer case 10a are shown as separated from each other. However, the outer case side wall 13a, the support column 14 and the like may be integrated. You may give a support | pillar structure in the whole case side wall. In such a case, as a locking structure in the case of multi-stage loading, for example, a convex locking portion 111a on the top surface of the top plate 11a and a concave locking portion 122a on the bottom surface of the outer case bottom plate 12a are provided at a plurality of locations. It may be provided.

  Next, the detailed structure of the middle case 2a will be described. FIG. 8 is a perspective view of the middle case bottom 20a shown in FIG. 9A is a plan view of the middle case bottom 20a shown in FIG. 8, and FIG. 9B is a vertical cross-sectional view taken along line IV-IV in FIG. 9A.

  The bearing 21 of the middle case bottom 20a supports the middle case rotating part 30 so as to be rotatable. Specifically, as shown in FIGS. 3A and 3B, the bearing 21 is loosely inserted into the rotating shaft hollow portion 132 of the rotating shaft 31 provided in the middle case rotating portion 30. For this reason, the inner diameter of the rotating shaft hollow portion 132 is formed larger than the outer diameter of the shaft of the bearing 21.

  As a result, the middle case rotating unit 30 is supported so as to be rotatable by the bearing 21 that is loosely inserted into the rotating shaft 31, and therefore when the rotational force is applied via the middle case side wall 32 or the like, the rotating shaft 31. Rotate (turn around) so that the storage space circulates around the center of rotation.

  As shown in FIG. 9A, the middle case bottom plate 22a is formed in a disk shape having a surface wider than the middle case rotating bottom plate. Specifically, the disc-shaped outer diameter of the middle case bottom plate 22 a is formed larger than the disc-shaped outer diameter of the middle case rotating bottom plate 34.

  The bearing 21 has a rotating shaft hollow portion at a center position (a position where the axis line J passes) of a surface (the upper surface of the middle case bottom plate 22a) facing the middle case rotating portion 30 and in a direction perpendicular to the surface of the middle case bottom plate 22a. It is formed with a length shorter than the depth of the groove in the axial direction 132 (direction of the axis J).

  A plurality of ball receiving holes 23 are provided on the upper surface side of the middle case bottom plate 22a on the circumference centered on the shaft of the bearing 21. For example, as shown in FIG. 8, the ball receiving hole 23 is on the circumference of a circle having a sufficiently smaller diameter than the outer diameter of the middle case bottom plate 22a (inner-dot chain line circumference N shown in FIG. 9A). 8 on the circumference of a circle that is larger than the circle having the smaller diameter and smaller than the outer diameter of the middle case bottom plate 22a (the outer periphery of the alternate long and short dash line M shown in FIG. 9A). Eight places are provided.

  The ball receiving hole 23 is formed in a hemispherical (bowl-shaped) groove at the above-described position of the middle case bottom plate 22a. For example, the longitudinal section of the ball receiving hole 23 is a hemispherical (bowl-shaped) section as shown in FIG. 9B. Further, the depth of the groove of the ball receiving hole 23 is formed smaller than the radius of the ball 5a described later.

  With the structure of the ball receiving hole 23 as described above, the user rotates the middle case rotating portion 30 supported by the bearing 21 via the plurality of balls 5a (rotation in the R direction in FIG. 1B). It can be operated smoothly.

  The guide rail groove portion 24 is formed on the bottom surface side of the middle case bottom plate 22a so that the guide rail 121 can slide within a certain range. For example, in the guide rail groove portion 24, as shown in FIG. 9A, two square grooves are formed in parallel with the longitudinal direction as a path from the vicinity of the front of the middle case 2a to the vicinity of the rear along the pulling direction. Is done. Further, the groove depth of the guide rail groove portion 24 is formed to be shallower than the height of the convex portion of the guide rail 121, and the width of the groove is slightly larger than the width of one convex portion of the guide rail 121. The

  By the guide means by the guide rail 121 and the guide rail groove portion 24 as described above, the user can easily pull out the middle case 2a from the outer case 10a, and when the middle case 2a is pulled out, it is unexpectedly pulled out of the outer case 10a. Can be prevented from coming off in any direction. Furthermore, it is possible to prevent the pulled out middle case 10a from being shifted to a state in which it is difficult to be accommodated in the outer case 10a. That is, the guide means assists the sliding operation as described above so that it can slide.

  Next, the detailed structure of the middle case rotating part 30 of the middle case 2a will be described.
