Detailed Description

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

In some of the drawings, some of the detailed reference numerals shown in the other drawings are omitted.

In the following embodiments, the directions such as the vertical direction will be described with reference to a state where the opening side faces the storage device provided, the front side being the front side, and the opposite side being the rear side. The same direction will be described in principle with reference to a state in which the storage body of the storage device is stored in the box as shown in fig. 1 to 3.

Fig. 1 to 7 are diagrams schematically showing an example of the storage device according to the first embodiment.

As shown in fig. 1 to 3, the storage device 1 of the present embodiment includes upper and lower rotation mechanism portions 20 and 21, and the upper and lower rotation mechanism portions 20 and 21 guide the storage body 10 so as to be rotatable about shafts 18 and 19 in the vertical direction and movable in the front-rear direction (storage depth direction) so that the storage body 10 can be turned over in the front-rear direction. The rotary storage device 1 as this storage device is configured such that the upper and lower rotary mechanism portions 20 and 21 are provided in a casing 2 which opens forward.

The rotary storage device 1 may be installed in a hallway corner, a hallway floor, or the like as a hallway storage device for storing shoes or the like. As will be described later, the rotary storage device 1 is configured to hold the rotary storage body 10 as a storage body in a load-bearing manner, and therefore has a higher load-bearing capability than a top-hung type, and can be installed in a kitchen or the like as a dish chamber-shaped storage for storing dishes, food materials, beverages, and the like. The rotary storage device 1 may be installed in a living room or the like as a rack-like storage box for storing various disk-shaped storage media, books, and the like. The rotary storage device 1 is not limited to such a device installed in a house, and may be installed in various buildings.

The casing 2 is formed into a substantially rectangular box shape when viewed from the front with its front opening. The housing 2 includes a top surface portion 3, a bottom surface portion 4, a back surface portion 5, and a pair of lateral side portions 6 and 6 in a lateral width direction (left and right), and thereby defines a housing space of the rotary housing 10. The storage space is formed such that a storage width dimension (a left-right dimension) is larger than a front-back dimension (a storage depth dimension).

The face portions 3, 4, 5, 6, and 6 may be made of a plate material, or the case 2 may be made of a wood material, a metal material, a synthetic resin material, or the like.

Further, a door may be provided to open and close the front opening of the case 2. Further, another storage space may be provided above or below the storage space of the rotary storage body 10. In this case, the upper and lower storage spaces may be partitioned by a bulkhead or the like. The case 2 may be opened at least at the front, or may be opened at both the front and rear sides. In the figure, the bottom portion 4 is formed in an upper bottom shape so as to be positioned above the lower ends of the side portions 6 and 6 on both sides, and a cross member extending in the front-rear direction is provided at the center in the lateral width direction (left-right direction) on the lower surface side.

The rotary container 10 is provided in the casing 2 so as to be rotatable 180 ° about the shafts 18 and 19 in the vertical direction and can be turned back and forth. In the present embodiment, the rotary container 10 is configured to include a frame 11 having a substantially rectangular frame shape in front view and a container 16 held by the frame 11. The rotary container 10 is configured such that the container 16 is disposed in the housing 11 to divide the container space into a plurality of layers.

The frame 11 includes an upper frame portion 12, a lower frame portion 13, and a pair of left and right vertical frame portions 14, 14.

As shown in fig. 2 and 3, the housing 11 is disposed in a substantially central portion in the front-rear direction in the case 2 in a state where the rotatable storage body 10 is stored in the case 2.

The frame 11 may be made of a rigid material such as a metal material.

The upper frame portion 12 and the lower frame portion 13 are elongated in the lateral width direction. The left and right vertical frame portions (vertical frame portions on both sides) 14, 14 are elongated in the vertical direction. The upper frame portion 12, the lower frame portion 13, and the vertical frame portions 14 and 14 on both sides are formed substantially rectangular when viewed in the longitudinal direction, and may be formed of, for example, a tubular material. The upper frame portion 12 and the lower frame portion 13 are disposed substantially parallel to each other, and the vertical frame portions 14 and 14 on both sides are disposed substantially parallel to each other.

Both ends in the longitudinal direction of the upper frame portion 12 are fixed to the upper ends of the vertical frame portions 14, 14 on both sides, and both ends in the longitudinal direction of the lower frame portion 13 are fixed to the lower ends of the vertical frame portions 14, 14 on both sides.

The frame body 11 including the upper frame portion 12, the lower frame portion 13, and the vertical frame portions 14, 14 on both sides may be integrally formed, or may be formed by connecting end portions of the respective frame portions 12, 13, 14 by fasteners such as screws, welding, or the like.

Further, a grip portion 17 that is gripped when the rotary container 10 is turned upside down as described later is provided on one of the vertical frame portions 14, 14 on both sides. In the illustrated example, the grip portions 17 and 17 are provided so as to protrude in the front-rear direction from the middle portion in the vertical direction of one of the vertical frame portions 14.

A housing portion 16 is provided so as to span between the vertical frame portions 14, 14 on both sides.

The housing portion 16 may be configured such that both end portions in the width direction (lateral width direction) are fixed to the vertical frame portions 14, 14 on both sides by appropriate fasteners, or may be configured such that they are detachably attached to the vertical frame portions 14, 14 on both sides. In the legend, the following examples are shown: insertion holes 15 are provided at a plurality of positions at intervals in the vertical direction on the inner side surfaces of the vertical frame portions 14, 14 on both sides facing each other, and the insertion holes 15 serve as engagement holding portions for detachably holding holders that hold both width-direction end portions of the storage portion 16. With such a configuration, the number and the height position of the storage units 16 can be changed.

Even when the front-rear dimension of the storage section 16 is relatively large, the rotatable storage body 10 is rotated and turned over by 180 ° as described later, thereby improving the article taking-in and taking-out performance.

In the illustrated example, the thin basket-shaped storage unit 16 and the thin box-shaped storage unit 16, which are open upward, are provided at a plurality of positions, including the upper and lower positions. The storage unit 16 may be a flat plate-like (shelf-like), tray-like, or bottle storage rack-like member, or may be a rod-like hook member or the like, which is formed in various shapes according to the type of the object to be stored. The objects to be stored in the rotary storage device 1 may be shoes such as shoes, clothes, umbrellas, hats, and the like, or may be storage media such as books, ornaments, tableware, foods, bottles, seasonings, various magnetic disks, and the like.

In the illustrated example, the storage unit 16 is illustrated as a substantially octagonal shape with four corners cut away in a plan view, but the present invention is not limited to this form. For example, the storage portion 16 may be formed with a C-chamfered or R-chamfered corner at four corners in a plan view.

In the illustrated example, the storage section 16 is held by the vertical frame portions 14 and 14 on both sides in a horizontal state so that the upper surface of the article placement section is horizontal. For example, the housing portion 16 may be held by the vertical frame portions 14 and 14 on both sides in a forward tilting state or a backward tilting state. In this case, the plurality of storage units 16 may be arranged to be alternately inclined vertically toward different sides. By inclining the storage section 16 in this manner, for example, when the object to be stored is a shoe or the like, the object can be efficiently stored. In addition, when the storage sections (shelves) in the forward tilted state and the storage sections (shelves) in the backward tilted state are provided vertically alternately as described above, the storage sections (shelves) in the backward tilted state can be switched to the forward tilted state by rotating the rotary storage body 10 to turn it over by 180 ° as will be described later, and the article taking-in and taking-out performance can be improved. With such a configuration, the storage space of the rotary storage device 1 (rotary storage body 10) can be effectively used.

The housing body for holding the housing portion 16 is not limited to the housing 11 described above. For example, the storage body 11 may be formed in various shapes such as a plate-like member that partitions the storage space in the front-rear direction, a rod-like member that extends in the up-down direction substantially coaxially with the shafts 18 and 19 along the up-down direction, and a member that is integrally provided with storage portions that are open at both the front and rear sides in the stored state.

The coupling shaft 28 may be provided coaxially with the upper end-side shaft 18 and may be fixed to the bearing 22. That is, the upper end side shaft 18 fixedly provided to the upper frame portion 12 may be rotatable with respect to the bearing portion 22 and the connecting shaft 28. Instead of this, the upper end-side shaft 18 and the coupling shaft 28 may be fixedly or integrally provided so as to be rotatable with respect to the holding member 27. Alternatively, instead of the upper end side shaft 18 being fixedly provided to the upper frame portion 12, a bearing portion or the like that rotatably holds the upper end side shaft 18 may be provided to the upper frame portion 12.

The holding member 27 is substantially square in plan view, and a holding hole 27b through which the coupling shaft 28 is inserted is provided at substantially the center thereof. The holding member 27 is movable up and down with respect to the connecting shaft 28.

The biasing mechanism 39 is substantially the same as described above, and is configured to bias the guide rollers 36, 36 on both sides in the lateral width direction toward the lower side that is the other side in the vertical direction so as to press the guide rollers 36, 36 against the inclined surfaces 48a, 48a of the lower rail portion 45. That is, the lower biasing mechanism 39 is configured to bias the lower holding member 37 downward. Further, biasing mechanisms 39, 39 are provided on both front and rear sides of the holding member 37, respectively. The biasing mechanisms 39 and 39 are compression coil springs inserted with the coupling shafts 38 and disposed between the holding member 37 and the flange- like retaining portions 38a and 38a provided at the upper ends of the coupling shafts 38 and 38 (see also fig. 6 c). That is, the biasing mechanisms 39 and 39 are configured to bias the holding member 37 so as to be pressed from above. The guide rollers 36, and 36 biased via the holding member 37 are in contact with the lower end side edges of the outer peripheral surfaces so as to be pressed against the corresponding inclined surfaces 48a and 48a on both sides in the lateral width direction. The biasing mechanism 39 is not limited to such a compression coil spring, as described above.

As shown in fig. 5, the lower end holding member 34 is disposed below the holding member 37, and has a downwardly open shape including an upper plate portion disposed below the holding member 37 and provided with coupling shafts 38, and side wall portions on both left and right sides and provided so as to hang down from both lateral end portions of the upper plate portion. In the present embodiment, the plurality of rolling elements 31A, 31B, and 31B are rotatably held by the lower end holding member 34. The plurality of rolling elements 31A, 31B, and 31B include a pair of rolling elements 31B and 31B provided in parallel with a space therebetween in the lateral width direction, and a rolling element 31A provided at a space on one side in the front-rear direction of the pair of rolling elements 31B and 31B. With such a configuration, the load of the rotary housing 10 and the object housed in the rotary housing 10 can be dispersed and received by the at least three rolling elements 31A, 31B, and 31B. Further, for example, in comparison with a configuration in which the three rolling elements 31A, 31B are provided in a row or in a straight row in the lateral width direction, that is, in a row, the load can be received in a three-point support manner, and the rotary housing 10 can be moved stably in the front-rear direction.

The plurality of rolling elements 31A, 31B, and 31B are disposed such that the upper end side shaft 18 and the lower end side shaft 19, which become the rotation center of the rotating case 10, are positioned between the pair of rolling elements 31B and the rolling element 31A on one side in the front-rear direction of the pair of rolling elements 31B and 31B in a plan view. That is, as shown in fig. 4(B), the rolling element 31A on one side in the front-rear direction of the pair of rolling elements 31B, 31B is provided so as to be located on one side in the front-rear direction with respect to the rotation center (the axial center of the lower end side shaft 19) of the rotation container 10 in a plan view. In addition, the pair of rolling elements 31B, 31B are provided so as to be located on the other side in the front-rear direction from the rotation center of the rotating case 10 in a plan view. With such a configuration, the load of the rotary housing 10 can be more stably dispersed and received by the pair of rolling elements 31B, 31B and the rolling element 31A on one side in the front-rear direction, and the rotary housing 10 can be more stably moved in the front-rear direction.

The plurality of rolling elements 31A, 31B, and 31B are provided so that the trajectories of the rolling elements 31A, 31B, and 31B are different in the lateral width direction. That is, the rolling elements 31A, 31B, and 31B are provided so that, as viewed in the front-rear direction along the moving direction of the rolling elements, contact portions with the groove bottom 47, which are trajectories of the rolling elements 31A, 31B, and 31B, do not overlap with each other. With such a configuration, the plurality of rolling elements 31A, 31B, and 31B do not roll on the same trajectory, and the rotary container 10 can be moved more stably in the front-rear direction while suppressing the dent, wear, and the like of the groove bottom 47 of the lower guide rail portion 45.

The plurality of rolling elements 31A, 31B, and 31B are constituted by a pair of rolling elements 31B and a central rolling element 31A, the pair of rolling elements 31B and 31B are provided at equal distances from the widthwise central portion of the housing 2, and the central rolling element 31A is provided so as to be positioned at the widthwise central portion of the housing 2 on one side in the front-rear direction of the pair of rolling elements 31B and 31B. That is, the central rolling elements 31A are provided so as to be positioned on one side in the front-rear direction of the upper end side shaft 18 and the lower end side shaft 19, and the upper end side shaft 18 and the lower end side shaft 19 serve as the rotation center of the rotation storage body 10 provided so as to be positioned in the center portion in the lateral width direction of the housing 2. With such a configuration, the load of the rotating case 10 can be dispersed and received by the pair of rolling elements 31B, 31B and the central rolling element 31A. Further, since the rolling elements 31A, 31B, and 31B are constituted by three, some of the rolling elements 31A, 31B, and 31B are less likely to lift up than a structure in which four or more rolling elements are provided, and the rolling elements 31A, 31B, and 31B stably roll on the groove bottom 47.

The pair of rolling elements 31B and 31B are provided such that an intermediate portion between them is located on the other side in the front-rear direction of the upper end side shaft 18 and the lower end side shaft 19, and the upper end side shaft 18 and the lower end side shaft 19 serve as the rotation center of the rotation housing 10. In the present embodiment, the central rolling element 31A is provided so as to be positioned on the front side of the pair of rolling elements 31B and 31B. The three rolling elements 31A, 31B, and 31B may be disposed at positions substantially equidistant from the upper end-side shaft 18 and the lower end-side shaft 19, which are located at the respective contact portions with the groove bottom 47 in a plan view, and which are located at the rotation center of the rotation housing 10.

In the present embodiment, the plurality of rolling elements 31A, 31B, and 31B are formed in a roller shape that is rotatable around the roller shafts 31Aa and 31Ba in the lateral width direction along the axial direction (see also fig. 4a and 6B). These roller shafts 31Aa and 31Ba are held so as to bridge the side walls on both sides of the lower end holding member 34. The rolling elements 31A, 31B, and 31B are formed to have the same size and the same shape (the same diameter).

In the present embodiment, the rolling elements 31A, 31B, and 31B include bearing portions (bearings) having an inner ring 31B fixed to the roller shafts 31Aa and 31Ba and an outer ring 31c provided rotatably with respect to the inner ring 31B (see fig. 6 c). With such a configuration, the rolling elements 31A, 31B, and 31B can smoothly rotate around the roller shafts 31Aa and 31 Ba.

The outer circumferential surfaces of the rolling elements 31A, 31B, and 31B may be formed of a metal outer ring 31c as described above, or may be formed of a resin or the like provided on the outer circumferential side so as to cover the outer ring 31 c. The bearing portions of the rolling elements 31A, 31B, and 31B are rolling bearings in which a plurality of balls or cylindrical rollers held by a cage (Retainer) are interposed between the inner ring 31B and the outer ring 31 c. Further, a suitable lubricant such as grease is sealed between the inner ring 31B and the outer ring 31c of the bearing portions of the rolling elements 31A, 31B, and a suitable sealing member (sealing member) is provided on both sides in the axial direction of the bearing portions so as to seal the inner space.

In the present embodiment, the suction bodies 32, 32 that suck the leaked lubricant are provided, and the suction bodies 32, 32 are disposed close to both axial side surfaces of the bearing portions of the rolling elements 31A, 31B. With such a configuration, even when a relatively high load is applied to the plurality of rolling elements 31A, 31B, and 31B, the lubricant sealed in the bearing portion can be prevented from dropping. This can prevent the lubricant from adhering to the groove bottom 47 of the lower rail portion 45 and dust and the like from adhering to the groove bottom 47.

These suction bodies 32, 32 are formed in a ring shape having openings through which the respective roller shafts 31Aa, 31Ba are inserted. Further, the suction bodies 32 and 32 are formed into a substantially disc-like shape (pad shape) having a relatively small dimension along the roller shafts 31Aa and 31 Ba. As the adsorbents 32 and 32, either a felt (woven cloth) type adsorbent having water absorption properties utilizing capillarity or a continuous bubble-like porous adsorbent (sponge) may be used.

The suction bodies 32 and 32 may be disposed in contact with or close to both axial side surfaces of the bearing portions so as to suck the leaked lubricant without causing excessive resistance to the outer ring 31c on the rotation side of the bearing portions of the rolling elements 31A, 31B, and 31B.

Further, receiving members 33, 33 for holding the suction bodies 32, 32 on both sides are provided on both sides in the axial direction of the bearing portions of the rolling elements 31A, 31B. These receiving members 33, 33 are formed in a ring shape having openings through which the respective roller shafts 31Aa, 31Ba are inserted.

The rolling elements 31A, 31B, and 31B of the lower end side center guide 30 that receive the load of the rotating container 10 and the object stored in the rotating container 10 are not limited to the above-described forms, and various modifications are possible. For example, the receiving members 33, 33 and the suction bodies 32, 32 may not be provided on both sides of the bearing portions of the rolling elements 31A, 31B in the axial direction. Instead of the roller-shaped form, the rolling elements 31A, 31B, and 31B may be formed in a ball (sphere) shape. Instead of providing three rolling elements 31A, 31B, and 31B, four or more or two or less rolling elements 31A, 31B, and 31B may be provided.

In the present embodiment, a movement suppressing unit 49 for suppressing the movement of the rotary container 10 in the stored state is provided. Further, a movement suppressing portion 49 is provided to the lower rail portion 45 so as to suppress the movement of the lower end side center guide 30 of the rotating container 10 in the stored state to the front side. In the present embodiment, the movement suppressing unit 49 is configured to allow the rotational storage body 10 to move (turn back and forth) when a load (operation load) equal to or greater than a predetermined load such as a manual force for moving (rotating) the rotational storage body 10 is applied. As shown in fig. 4(b), the movement suppressing portion 49 is configured to have an advancing/retreating portion 49a that advances and retreats in the groove width direction with respect to the inner walls 48, 48 on both sides of the guide groove 46 of the lower guide rail portion 45. Further, movement suppression portions 49, 49 are provided on the inner side walls 48, 48 on both sides, respectively, and the movement suppression portions 49, 49 have advancing and retreating portions 49a, 49a arranged in an opposed shape. The advancing and retreating portions 49a, 49a are formed in a projecting curved shape projecting toward the center side in the groove width direction in plan view. The movement-inhibiting portions 49, 49 may be spherical plungers or pin plungers having spherical or pin-shaped advancing and retreating portions 49a, 49a at the distal end of the cylindrical portion and incorporating biasing members such as springs for biasing the advancing and retreating portions 49a, 49a in the advancing and retreating directions.

As shown in fig. 4(b) and fig. 6(a) and (b), engaging recesses 35 and 35 as engaging portions that engage with advancing and retreating portions 49a and 49a through which the movement suppressing portions 49 and 49 advance and retreat are provided on both sides in the lateral width direction of the lower end side center guide body 30. These engaging recesses 35, 35 are provided so as to open outward in the lateral width direction on both side wall portions of the lower end holding member 34. The advancing and retreating portions 49a, 49a engaged with the engaging recesses 35, 35 so as to be inserted thereinto can suppress an unexpected movement of the rotary container 10 in the stored state. When a load greater than or equal to a predetermined value is applied to move the rotary container 10, the rear side edges of the engaging recesses 35, 35 move over the advancing and retreating portions 49a, 49a as the advancing and retreating portions 49a, 49a retreat, and the engagement of the engaging recesses 35, 35 by the advancing and retreating portions 49a, 49a is released. The engaging recesses 35, 35 are formed in a concave curved shape or a shape that expands toward the opening side in a plan view, corresponding to the shape of the advancing and retreating portions 49a, 49a of the movement restraining portions 49, 49 in a plan view. Further, inclined surface portions inclined so as to descend toward the widthwise central portion side as they go toward the rear side are provided so as to be continuous with at least rear side edges of both front and rear side edges of the engagement concave portions 35, 35.

The movement suppressing portions 49 and the engaging portions 35 and 35 are not limited to the above-described configurations, and various modifications are possible. For example, the movement suppressing portions 49 and 49 may be formed as leaf spring-like portions or as magnetic clip-like portions that are substantially elastically deformable in the groove width direction. Further, the movement suppressing portions 49 and 49 are not limited to the configuration in which the rotary case 10 can be moved (rotated) if a load of a predetermined amount or more is applied as described above, and may be configured as a lock mechanism that needs to be manually released when the rotary case 10 is moved.

In addition, the movement suppressing portions 49, 49 may be provided on the upper rail portion 40 instead of or in addition to the lower rail portion 45. In this case, an engagement portion may be provided at an appropriate position of the upper end side center guide body 25.

In the present embodiment, the upper and lower rotation mechanism units 20 and 21 are provided with a rotation path guide mechanism for guiding the rotation path of the rotary container 10 so as to be restricted. The rotation locus guide mechanism includes side guide bodies 24, 24 and curved guide grooves 51, 51 for guiding the side guide bodies 24, 24 upward and downward, and the side guide bodies 24, 24 are provided on both upper and lower sides of one side portion in the lateral width direction of the rotation container 10 in the stored state. These curved guide grooves 51, 51 guide the side guide bodies 24, 24 so as to move to the back side as they go toward the widthwise central portion.

In the present embodiment, the upper and lower side guides 24 and 24 have the same structure. These side guides 24, 24 are provided so as to be aligned with each other in a plan view. As will be described later, these side guides 24 and 24 are configured to move on a substantially circular arc centered on the upper and lower shafts 18 and 19 of the rotating container 10 when the rotating container 10 is guided and rotated by the upper and lower rotating mechanism portions 20 and 21.

In the present embodiment, the side guide bodies 24 and 24 are provided at one longitudinal side portion of the upper frame 12 and the lower frame 13. In the present embodiment, the side guide bodies 24 and 24 are side guide rollers 24 and 24 that are rotatable about roller shafts 24a and 24a, respectively, which are vertical axes.

The roller shafts 24a, 24a of these side guide rollers 24, 24 are provided coaxially with each other, and are provided on the upper frame portion 12 and the lower frame portion 13 so as to protrude outward in the vertical direction, respectively. Instead of rotatably holding the side guide rollers 24 and 24 on the roller shafts 24a and 24a fixed to the upper frame 12 and the lower frame 13, bearing portions may be provided on the upper frame 12 and the lower frame 13 to rotatably hold the roller shafts 24a and 24 a. Instead of such a rotatable member, a pin-shaped or block-shaped side guide 24, 24 may be used.

The upper and lower curved guide grooves 51, 51 are provided so as to open to the center side in the vertical direction and extend substantially in the lateral width direction. In the present embodiment, the upper and lower curved guide grooves 51, 51 are provided in curved guide rail portions 50, 50 fixed to extend along the top surface 3a and the bottom surface 4a of the casing 2, respectively. Further, both or one of the upper and lower curved guide grooves 51, 51 may be provided directly or embedded in the upper and lower surfaces 3, 4 (the top surface 3 and the bottom surface 4) of the casing 2. The upper and lower curved rail portions 50 and 50 (curved guide grooves 51 and 51) are provided so as to be vertically reversed from each other, and are positioned on the top surface 3a and the bottom surface 4a of the casing 2 in plan view. Hereinafter, the lower curved rail portion 50 (curved guide groove 51) will be described as an example.

As shown in fig. 3, the curved guide groove 51 is configured to connect a curved groove portion 52 at the center side in the lateral width direction and linear groove portions 53, the curved groove portion 52 is formed in a curved shape protruding to the rear side in a plan view, and the linear groove portions 53, 53 are provided to extend in the lateral width direction on both sides in the lateral width direction of the curved groove portion 52.

The curved guide groove 51 is formed in a substantially rectangular groove shape having a substantially rectangular shape as viewed in the groove longitudinal direction, and the groove width and the groove depth are substantially equal to each other over the entire length (see fig. 4 (a)). The curved guide groove 51 has a groove width dimension corresponding to the outer diameter of the side guide roller 24. That is, the curved guide groove 51 has a groove width dimension that faces the two groove side walls with a slight gap therebetween, so that the outer peripheral surface of the side guide roller 24 rolls in contact with one of the groove side walls. In the illustrated example, a part of the side guide roller 24 is exposed outside the curved guide groove 51, but the entire side guide roller 24 may be accommodated in the curved guide groove 51.

The curved groove portion 52 is provided so that both lateral end portions of the boundary portion with the linear groove portions 53, 53 are positioned at a substantially central portion in the depth direction of the storage space of the case 2. The curved groove portion 52 is provided so as to be located on the back side of the storage space as it is separated from the linear groove portions 53, 53 on both sides, that is, as it is directed toward the widthwise central portion, and the innermost portion is located at the widthwise central portion of the storage space.

As shown in fig. 7(a) to (c), when the rotary container 10 rotates, the curved groove portion 52 is formed in a substantially arc shape centered on the upper and lower shafts 18 and 19 of the rotary container 10 in the most forward position. The center angle and the radius of curvature of the curved groove portion 52 may be appropriately set so as not to contact the box 2 when the rotary container 10 rotates, depending on the depth and width of the container space, the shape of the container portion 16 of the rotary container 10 in plan view, and the like. The central angle of the curved groove portion 52 may be, for example, about 60 ° to 120 °. The radius of curvature of the curved groove portion 52 may be increased as the ratio of the lateral width to the depth of the storage space (the rotatable storage body 10) is increased, for example.

The linear groove portions 53 and 53 are provided so as to be continuous with both lateral end portions of the curved groove portion 52. These linear grooves 53, 53 are provided so as to be located at a substantially central portion in the depth direction of the housing space of the case 2 and extend in the lateral width direction. The boundary between the linear groove portions 53 and the curved groove portion 52 is formed in a curved shape so that the side guide roller 24 moves smoothly.

The side guide rollers 24 are positioned in the linear groove portions 53 and 53 on both sides thereof in the state of housing the rotary housing body 10 and in the initial and final states when the rotary housing body 10 is rotated (see fig. 3 and 7 (d)).

As shown in fig. 3 and 7, in the rotary storage device 1 configured as described above, the rotary storage body 10 rotates as follows and is turned upside down.

In an initial state when the rotating container 10 is rotated from a state in which the rotating container 10 is stored, the side guide roller 24 moves toward the center in the lateral width direction along one of the linear groove portions 53 of the curved guide groove 51, and the upper and lower center guide members 25 and 30 move forward. When the side guide rollers 24 reach the curved groove portions 52 of the curved guide grooves 51, the side guide rollers 24 move so as to draw an arc along the curved groove portions 52 so that the rotating case 10 rotates about the upper end side shaft 18 and the lower end side shaft 19 as substantially pivot points. When the side guide rollers 24 reach the other linear groove portion 53 in the final stage of the rotation of the rotatable container 10, the side guide rollers 24 move outward in the lateral width direction along the other linear groove portion 53, and the upper and lower center guide bodies 25 and 30 move rearward. Thereby, the rotary container 10 is rotated 180 ° about the vertical shafts 18 and 19, and is turned back and forth. In this way, the rotating storage device 1 can change (switch) the front and rear of the rotating storage body 10 by rotating the rotating storage body 10 about the shafts 18, 19 while moving the shafts 18, 19 on the upper and lower sides of the rotating storage body 10 in the front and rear directions.

The storage device (rotary storage device) 1 of the present embodiment can effectively reduce the depth dimension of the casing 2 and can smoothly move the storage body (rotary storage body) 10 in the front-rear direction by adopting the above-described configuration.

That is, the rotating mechanism portions 20 and 21 are provided in the case 2 opened forward, and the rotating mechanism portions 20 and 21 guide the rotating container 10 to be rotatable about the shafts 18 and 19 in the vertical direction and movable in the front-rear direction so that the rotating container can be turned over in the front-rear direction. Therefore, the stored object can be efficiently stored in the rotary storage body 10, or the stored object can be easily taken out by rotating the rotary storage body 10. The rotary container 10 can be rotated about the shafts 18 and 19 in the vertical direction while being moved in the front-rear direction with respect to the case 2. This prevents the rotatable container 10 from protruding rearward from the state of being accommodated in the case 2 when the rotatable container 10 is rotated. That is, the space for rotation of the rotary container 10 required for the back side of the rotary container 10 in the state of being stored in the box 2 can be reduced, and the depth dimension of the storage portion 16 of the rotary container 10 can be secured and the depth dimension of the box 2 can be effectively reduced.

Further, at least one of the upper and lower rotation mechanism portions 20 and 21 is provided with an urging mechanism 29 or 39, and the urging mechanism 29 or 39 urges the guide roller 26 or 36 to press the inner wall (inclined surface) 43 or 48(48a) of the guide rail portion 40 or 45 extending in the front-rear direction. Therefore, it is possible to suppress formation of a gap between the inner walls (inclined surfaces) 43 and 48(48a) of the guide rail portions 40 and 45 and the guide rollers 26 and 36, and to guide the guide rollers 26 and 36 along the inner walls 43 and 48a of the guide rail portions 40 and 45. Accordingly, when the rotary container 10 is rotated while being moved in the front-rear direction, the occurrence of rattling and noise caused by the rattling can be suppressed at least at one of the upper and lower rotating mechanism portions 20 and 21, and the rotary container 10 can be smoothly moved in the front-rear direction.

In the present embodiment, the guide rollers 26 and 36 guided by the guide rail portions 40 and 45 and the biasing mechanisms 29 and 39 for biasing the guide rollers 26 and 36 are provided in both the upper and lower rotation mechanism portions 20 and 21. Therefore, the swing of the rotary housing 10 on both the upper and lower sides and the generation of abnormal noise caused by the swing can be suppressed, and the rotary housing 10 can be moved more smoothly in the front-rear direction.

In the present embodiment, the guide rollers 26, 36, and 36 are provided at intervals in the front-rear direction. Therefore, the rotary container 10 can be moved stably in the front-rear direction, as compared with a configuration in which a single guide roller 26, 36 is provided.

In the present embodiment, the guide rollers 26, 36 are provided on both sides in the lateral width direction so as to abut against the inner side walls (inclined surfaces) 43, 48(48a) on both sides of the guide rail portions 40, 45, respectively. Therefore, compared to a configuration in which only the guide rollers 26 and 36 are provided to abut against the inner side walls (inclined surfaces) 43 and 48(48a) in one lateral width direction, the play of at least one side of the upper and lower rotation mechanism sections 20 and 21 and the generation of abnormal noise caused by the play can be more effectively suppressed. In addition, the rotary container 10 can be moved more smoothly and stably in the front-rear direction.

In the present embodiment, inclined surfaces 43, 48a inclined so as to expand toward one side in the vertical direction are provided on the inner side walls 43, 48 on both sides of the guide rail portions 40, 45. The biasing mechanisms 29, 39 bias the guide rollers 26, 36 toward the other side in the vertical direction so that the guide rollers 26, 36 on both sides in the lateral width direction are pressed against the inclined surfaces 43, 48 a. Therefore, the biasing direction is inclined with respect to the inclined surfaces 43, 48a, and is substantially along the roller shafts 27a, 37a, and 37a of the guide rollers 26, 36, and 36. Thus, for example, compared to a configuration in which the biasing mechanisms 29 and 39 for biasing the guide rollers 26, 36, the shafts, the bearing portions, and the like in the radial direction of the guide rollers 26, 36, and 36, which are substantially perpendicular to the inner walls 43, 48, and 48, are provided, it is possible to effectively suppress vibrations and the like in the width direction of the guide rail portions with respect to the guide rollers 26, 36, and 36 of the guide rail portions 40 and 45.

In the present embodiment, holding members 27 and 37 are provided to rotatably hold the plurality of guide rollers 26, 36 and 36. The biasing mechanisms 29 and 39 bias the holding members 27 and 37 so that the guide rollers 26, 36 and 36 are pressed against the inner walls (inclined surfaces) 43 and 48(48a) of the guide rail portions 40 and 45. Therefore, the structure can be simplified as compared with the structure in which the biasing mechanisms 29 and 39 that individually bias the shafts, bearings, and the like of the guide rollers 26, 36, and 36 are provided.

Next, an example of a storage device according to another embodiment of the present invention will be described with reference to the drawings.

Fig. 8 is a diagram schematically showing an example of a rotary housing apparatus as a housing apparatus of the second embodiment.

Note that differences from the first embodiment described above will be mainly described, and the same components will be denoted by the same reference numerals, and description thereof will be omitted or simplified.

As shown in fig. 8, the rotating and housing apparatus 1A of the present embodiment is different from the first embodiment mainly in the configuration of the central guide bodies 25A, 30A of the vertical rotating mechanism portions 20A, 21A.

In the present embodiment, the directions of the roller shafts 27Aa and 37Aa of the guide rollers 26 and 36 of the upper and lower central guide bodies 25A and 30A are set to be parallel to the inclined surfaces 43 and 48a of the inner walls 43 and 48 of the upper and lower guide rail portions 40 and 45. That is, the roller shafts 27Aa and 37Aa of the guide rollers 26 and 36 are inclined so as to be parallel to the inclined surfaces 43 and 48a when viewed in the front-rear direction. In the present embodiment, the guide rollers 26, 36, and 36 are also provided on both sides in the lateral direction. The roller shafts 27Aa, 37Aa, and 37Aa of the guide rollers 26, 36, and 36 on both sides in the lateral width direction are inclined so as to be parallel to the corresponding inclined surfaces 43, 48a, and 48 a. The roller shafts 27Aa, 37Aa, and 37Aa of the guide rollers 26, 36, and 36 may be parallel to the corresponding inclined surfaces 43, 48a, and 48a as viewed in the front-rear direction, or may be inclined with respect to the direction along the vertical direction or the vertical direction as viewed in the lateral width direction.

The roller shafts 27Aa, 27Aa on both sides in the lateral width direction of the upper end side center guide body 25A are provided so as to be inclined toward the lateral width direction center side as going toward the upper end side, with the upper end side being closer to the lateral width direction center side than the lower end side. In the present embodiment, the upper surfaces of both ends in the lateral width direction of the holding member 27A provided with the roller shafts 27Aa, 27Aa of the upper end side center guide body 25A are inclined so as to be orthogonal to the directions of the respective roller shafts 27Aa, 27Aa on both sides in the lateral width direction. That is, the upper surfaces of both ends in the lateral width direction of the holding member 27A are formed in an inclined plane shape that descends from each outer end edge in the lateral width direction toward the center side in the lateral width direction. The lateral width direction both end portions of the holding member 27A are bent upward with respect to the lateral width direction center portion so that the upper surfaces thereof are perpendicular to the directions of the roller shafts 27Aa and 27Aa on both sides in the lateral width direction. The guide rollers 26, 26 held on both sides in the lateral width direction of the holding member 27A are in contact with the corresponding inner side walls (inclined surfaces) 43, 43 on both sides in the lateral width direction of the upper guide rail portion 40 so that substantially the entire axial direction of each outer peripheral surface is pressed, unlike the first embodiment.

The roller shafts 37Aa, 37Aa on both sides in the lateral width direction of the lower end side center guide body 30A are provided so as to be inclined outward in the lateral width direction toward the upper end side with their upper end sides being located more outward in the lateral width direction than the lower end side. In the present embodiment, the upper surfaces of both ends in the lateral width direction of the holding member 37A provided with the roller shafts 37Aa, 37Aa of the lower end side center guide 30A are inclined so as to be orthogonal to the directions of the respective roller shafts 37Aa, 37Aa on both sides in the lateral width direction. That is, the upper surfaces of both ends in the lateral width direction of the holding member 37A are formed in a tilted surface shape rising from each outer end edge in the lateral width direction toward the center side in the lateral width direction. The lateral width direction both end portions of the holding member 37A are bent downward with respect to the lateral width direction center portion so that the upper surfaces thereof are perpendicular to the lateral width direction both side roller shafts 37Aa, 37 Aa. The guide rollers 36, 36 held on both sides in the lateral width direction of the holding member 37A are in contact with each other so that substantially the entire axial direction of each outer peripheral surface is pressed by the corresponding inclined surfaces 48a, 48a on both sides in the lateral width direction of the lower guide rail portion 45, unlike the first embodiment.

The rotary housing device 1A according to the present embodiment also achieves substantially the same effects as those of the first embodiment. In the present embodiment, the directions of the roller shafts 27Aa, 37Aa, and 37Aa of the guide rollers 26, 36, and 36 on both sides in the lateral width direction are set to be parallel to the inclined surfaces 43, 48a, and 48a of the inner side walls 43, 48, and 48. Therefore, the outer peripheral surfaces of the guide rollers 26, 36 can be stably brought into contact with the inclined surfaces 43, 48 a. Accordingly, compared to the first embodiment in which the direction of the roller shafts 27a, 37a is inclined with respect to the inclined surfaces 43, 48a, the load applied to the guide rollers 26, 36, and the local wear of the guide rollers 26, 36 and the rail portions 40, 45 can be suppressed.

Next, an example of a storage device according to still another embodiment of the present invention will be described with reference to the drawings.

Fig. 9 and 10 are diagrams schematically showing an example of a rotary storage device as a storage device according to a third embodiment.

Note that, differences from the above-described embodiments will be mainly described, and the same components will be denoted by the same reference numerals, and description thereof will be omitted or simplified.

As shown in fig. 9, the rotating storage device 1B of the present embodiment is different from the above-described embodiments mainly in the structure of the upper end side center guide body 25B of the upper rotation mechanism section 20B.

In the present embodiment, two guide rollers 26, 26 are provided at a distance in the front-rear direction on one side in the lateral width direction, and one guide roller 26 is provided between the two guide rollers in the front-rear direction on the other side in the lateral width direction. That is, in the present embodiment, the upper end side center guide body 25B is provided with three guide rollers 26, 26. The three guide rollers 26, 26 are disposed so as to be located at the apexes of a triangle, respectively, in a plan view (viewed in the up-down direction).

In the present embodiment, the three guide rollers 26, 26 are disposed so as to be located at the apexes of a substantially regular triangle, respectively, in a plan view. That is, the three guide rollers 26, 26 are provided at substantially equal distances from each other. That is, in the present embodiment, the one guide roller 26 on the other lateral width direction side is provided substantially at the center between the two guide rollers 26, 26 on the one lateral width direction side in the front-rear direction. The other guide roller 26 on the other side in the lateral width direction is provided at a position substantially coincident with the coupling shaft 28 (the upper end side shaft 18) in the front-rear direction. In place of this, the three guide rollers 26, 26 may be arranged so as to be positioned at the apexes of triangles having other shapes such as substantially isosceles triangles, substantially right-angled triangles, and scalene triangles in plan view.

As shown in fig. 10(b), the roller shafts 27Aa, 27Aa of the guide rollers 26, 26 are arranged in parallel with the inner walls 43, 43 of the upper rail portion 40 formed in an inclined plane, as in the second embodiment. Further, as described above, the widthwise opposite end portions of the plate-like holding member 27A are bent upward with respect to the widthwise central portion so that the upper surfaces thereof are perpendicular to the directions of the roller shafts 27Aa, 27Aa on both sides in the widthwise direction.

In the present embodiment, as shown in fig. 10(a) and (B), the upper end side center guide body 25B is provided with a shaft insertion portion 25a, and the shaft insertion portion 25a is provided with a holding hole 25B communicating with the holding hole 27B of the holding member 27A. The shaft insertion portion 25a is fixed to one side in the thickness direction of the plate-shaped holding member 27A, and is block-shaped in the drawing. The holding hole 25b of the shaft insertion portion 25a is formed to have substantially the same diameter as the holding hole 27b of the holding member 27A and a diameter corresponding to the outer diameter of the coupling shaft 28. The coupling shaft 28 is inserted into the holding hole 25b of the shaft insertion portion 25a and the holding hole 27b of the holding member 27A, and the holding member 27A is held to be movable in the axial direction of the coupling shaft 28.

The rotary housing device 1B according to the present embodiment also achieves substantially the same effects as those of the above-described embodiments. In the present embodiment, as described above, the three guide rollers 26, 26 are provided on the upper end side center guide body 25B so as to be positioned at the apexes of a triangle in plan view. Therefore, as described above, the simplification of the structure can be achieved as compared with the structure in which four guide rollers 26 are provided. Even if the number of the guide rollers 26 is reduced in this way, all of the three guide rollers 26, 26 can be stably brought into contact with the inner side walls 43, 43 of the upper guide rail portion 40. That is, in the case where a plurality of guide rollers 26 such as four are provided, if the upper end side center guide body 25B is inclined around the connection shaft 28, it may be difficult to bring all the guide rollers 26 into contact with the inner side walls 43, but such a situation can be suppressed. In the present embodiment, only the upper end side center guide body 25B is illustrated, but three guide rollers 36, 36 may be provided on the lower end side center guide bodies 30, 30A substantially in the same manner as the upper end side center guide body 25B.

In addition, in the present embodiment, since the shaft insertion portion 25a is provided as described above, the holding member 27A can be formed in a plate shape to simplify the structure, and the dimension in the axial direction of the holding holes 25b and 27b through which the coupling shaft 28 is inserted can be increased. This can suppress the inclination of the holding member 27A when moving in the axial direction of the coupling shaft 28. The shaft insertion portion 25a is not limited to the block shape shown in the drawing, and may be a cylindrical shape. Further, the retaining member 27A may be integrally provided with a boss-shaped shaft insertion portion 25a so as to increase the dimension of the retaining hole 27b in the axial direction. The shaft insertion portion 25A may be provided in the upper end side central guide bodies 25 and 25A and the lower end side central guide bodies 30 and 30A in the above embodiments.

In the above embodiments, the example in which four or three guide rollers 26 and 36 are provided on the upper and lower central guide bodies 25, 25A, 25B, 30, and 30A so as to be positioned on both sides in the front-rear direction and both sides in the lateral width direction is shown, but the present invention is not limited to this form. The upper and lower central guide bodies 25, 25A, 25B, 30A may be provided with five or more or two or less guide rollers 26, 36.

In the above embodiments, the biasing mechanisms 29 and 39 for biasing the holding members 27, 27A, 37 and 37A that rotatably hold the guide rollers 26, 36 and 36 are provided, but the present invention is not limited to this configuration. Biasing mechanisms 29 and 39 for biasing the guide rollers 26, 36 and 36, respectively, may be provided.

In the above embodiments, the inclined surfaces 43, 48a are provided on the upper and lower rail portions 40, 45, but the inclined surfaces 43, 48a may not be provided. In this case, the biasing mechanisms 29 and 39 and the like may be appropriately deformed.

In the above embodiments, the guide rollers 26 and 36 pressed against the inner side walls 43 and 48 of the guide rail portions 40 and 45 by the biasing mechanisms 29 and 39 are provided in the upper and lower rotation mechanism portions 20, 20A, 20B, 21 and 21A, respectively. The guide rollers 26 and 36 pressed against the inner side walls 43 and 48 of the guide rail portions 40 and 45 by the biasing mechanisms 29 and 39 may be provided only on one side of the vertical rotation mechanism portions 20, 20A, 20B, 21 and 21A. In this case, an appropriate guide mechanism may be provided on the other side of the vertical rotation mechanism portions 20, 20A, 20B, 21A. In addition, as in the above embodiments, in the case where the lower rail portions 45 of the lower rotating mechanism portions 21 and 21A are of a lower load type receiving the load of rotating the container 10, at least the upper rotating mechanism portions 20, 20A, and 20B that are likely to vibrate in the lateral direction may be configured as in the above embodiments.

In the above embodiments, the lower guide rail portions 45 of the lower rotation mechanism portions 21 and 21A are of a lower load type receiving the load of the rotating storage body 10, but may be of an upper suspension type in which the rotating storage body 10 is held in a suspended state by the upper guide rail portions 40. In this case, at least the lower rotation mechanism portions 21 and 21A which are likely to vibrate in the lateral direction may be configured as in the above embodiments. In this case, each of the upper and lower rotating mechanism units 20, 20A, 20B, 21A may be deformed as necessary.

In the above embodiments, the upper and lower side guide bodies 24 and the upper and lower curved guide grooves 51 and 51 constituting the rotational locus guide mechanism are provided in the upper and lower rotation mechanism sections 20, 20A, 20B, 21 and 21A, but the present invention is not limited to this configuration. For example, the side guide 24 and the curved guide groove 51 constituting the rotational locus guide mechanism may be provided only on one of the vertical and vertical rotation mechanism sections 20, 20A, 20B, 21A. The rotation trajectory guide mechanism is not limited to this form, and a connection arm having both end portions rotatably connected to each other may be provided at one lateral width direction position in the stored state of the rotary storage body 10 and at the rear end portion of the guide rail portions 40 and 45. Such a mechanism for regulating the rotation locus of the rotary container 10 may not be provided. The specific configuration of each part of the rotary storage devices 1, 1A, and 1B according to the above embodiments is not limited to the above configuration, and various modifications may be made in addition to the above configuration.
