Description

Technical Field

[0001] The present application relates to a storage warehouse and a storage structure suitable for storing articles such as foodstuffs and pharmaceuticals, appropriately replenishing new articles, and using them from old ones.

Background Art

[0002] In recent years, in response to the increasing awareness of disaster prevention, the number of cases where storage warehouses for disaster preparedness such as earthquakes are installed in private houses is increasing. In this type of storage warehouse, for example, foodstuffs, drinking water, pharmaceuticals, sanitary products, etc. are stored. Many of these articles have expiration dates set. Therefore, in order to prevent old articles from being pushed downwards or to the back and expiring, it is necessary to regularly check the expiration dates of the stored articles, preferentially consume (use or dispose of) old ones, and replenish new ones.

[0003] Storage facilities that can accommodate such a "first-in, first-out" method are also used in, for example, logistics warehouses and assembly factories. However, since they are large-scale facilities that electrically control the conveyance of articles using conveyors, lifters, etc., or move articles using gentle slopes, they are not suitable for private houses. As a relatively compact storage facility that enables "first-in, first-out", a type in which a plurality of box shelves are attached to an endless chain and the position of the box shelves is changed by circulating the chain is known (for example, Patent Documents 1 to 3, etc.). However, in this type of storage facility, individual box shelves have to be made small in order to secure space for circulating the box shelves, and the substantial storage capacity tends to be reduced. In addition, in a structure in which an endless chain is driven by a motor or the like, there is also the inconvenience that it cannot be used when a power outage occurs due to a disaster or the like.

Patent Document 2

[0005] The invention disclosed in the present application has been made in view of the above circumstances, and aims to provide a non-electric storage warehouse and a storage structure that have a simple structure that can be installed in individual houses and the like and can accommodate the "first-in, first-out" method. [Means for Solving the Problems]

[0006] In order to achieve the above object, the storage repository of the invention disclosed in the present application includes an outer box enclosing a storage space with a uniform cross-section in the vertical direction, a plurality of inner boxes that are stacked in an individually independent state without being connected to each other and are stored in the storage space, a door attached to the outer box so as to be able to open the front of the storage space, an inner box receiver installed on the side plate of the outer box to support the inner box at a predetermined height, a movable shelf plate installed on the outer box below the inner box receiver and held so as to be able to move up and down, and a non-electric pushing means for raising the movable shelf plate to the height of the inner box receiver. The inner box receiver is configured to be deformable into both a receiving form that protrudes into the storage space from the side plate of the outer box and engages with the bottom surface or side surface of the inner box, and a floating form that retracts laterally by being pushed up from below to allow the inner box to rise. When the door is closed, the lowermost inner box is supported by the inner box receiver. When the door is opened and the uppermost inner box is taken out, and the movable shelf plate is pushed down against the pushing means, the inner boxes below the second stage are maintained in a state of being supported by the inner box receiver, and a replenishment space having a height of at least one inner box is formed between the movable shelf plate and the inner box receiver, enabling re-storage. When the pushing means is activated with the inner box re-stored in the replenishment space, the movable shelf plate rises, and the re-stored inner box overlaps the lower side of the inner box supported by the inner box receiver, and the plurality of inner boxes are lifted together by one stage, so that the re-stored inner box is supported by the inner box receiver, adopting the basic configuration as described above.

[0007] Furthermore, in the storage repository of the invention disclosed in the present application, an upward restriction device that operates in conjunction with the opening and closing of the door is provided on the side plate of the outer box surrounding the replenishment space. When the door is opened, the movable shelf plate is pushed down, and the inner box is re-stored in the replenishment space, the upward restriction device engages with the re-stored inner box to restrict the upward movement of the re-stored inner box. When the door is closed, the restricted state is released, the movable shelf plate rises together with the re-stored inner box, and the re-stored inner box is pushed up to the height at which it is supported by the inner box receiver, adopting the additional configuration as described above.

[0008] The upward restricting tool is attached via a biasing member so as to protrude into the replenishment space from the side plate of the outer box, and an engaging member is attached to the door such that when the door is closed, the upward restricting tool is pressed against the side plate side of the outer box, and when the door is opened, the engaging member is separated from the upward restricting tool.

[0009] Furthermore, in the storage and storage warehouse of the invention disclosed in the present application, a second upward restricting tool that operates in conjunction with the opening and closing of the door is provided above the storage space. When the door is opened, the second upward restricting tool engages with the top surface of the uppermost inner box, and when the door is closed, the second upward restricting tool disengages from the storage space. An additional configuration is adopted.

[0010] In addition, the storage and storage structure of the invention disclosed in the present application includes a storage space that is continuous in the vertical direction, a plurality of inner boxes that are stacked in a state of being independent of each other and individually stored in the storage space, a door that opens and closes the storage space, an inner box receiving tool that is installed on the side wall surrounding the storage space and supports the inner box at a predetermined height, a movable shelf board that is held so as to be movable up and down below the inner box receiving tool, and a non-electric pushing-up means that raises the movable shelf board to the height of the inner box receiving tool. The inner box receiving tool is configured to be deformable into both a receiving form that protrudes from the side wall into the storage space and engages with the bottom surface or side surface of the inner box, and a floating form that retracts laterally by being pushed up from below and allows the inner box to rise. When the door is closed, the lowermost inner box is supported by the inner box receiving tool. When the door is opened, the uppermost inner box is taken out, and the movable shelf board is pushed down against the pushing-up means, the inner boxes below the second stage are held in a state of being supported by the inner box receiving tool, and a replenishment space having a height of at least one inner box is formed between the movable shelf board and the inner box receiving tool, enabling re-storage. When the pushing-up means is activated with an inner box re-stored in the replenishment space, the movable shelf board rises, and the re-stored inner box overlaps the lower side of the inner box supported by the inner box receiving tool, and the plurality of inner boxes are lifted together by one stage, so that the re-stored inner box is supported by the inner box receiving tool. It is characterized by this.

Effect of the Invention

[0011] The storage bin and storage structure according to the invention disclosed in the present application store a plurality of inner boxes containing articles in an outer box in a stacked manner with each inner box being independent and not connected to each other. When the oldest articles are consumed by taking out the topmost inner box and then the inner box is replenished with new articles and re-stored at the bottommost position, the "first-in, first-out" of the stored articles is realized by swapping the positions of the inner boxes. The swapping method of taking out the articles to be consumed from the topmost position and replenishing the new articles at the bottommost position makes it easy for the user to grasp the storage status of the articles and also provides a user-friendly experience with less physical burden when taking in and out the articles.

[0012] For the movement of the stacked inner boxes, a pushing means that does not rely on electric power, such as a spring member, is adopted. Therefore, it can be used without any problems even in the event of a power outage due to a disaster or the like. Also, since a complex drive mechanism or the like is not used, it is easy to secure a storage capacity while being compact. Therefore, it can be installed at low cost in individual houses or apartment houses, and maintenance is also easy.

Embodiments for Carrying Out the Invention

[0014] Hereinafter, embodiments of the invention disclosed in the present application will be described with reference to the drawings. FIGS. 1 to 8 show the structure of the storage repository 1 according to the embodiments of the invention disclosed in the present application. In the following, when explaining the relative positional relationship of parts and members and the direction of operation, the surfaces shown in FIGS. 1 to 4 are defined as the front, and the left - right direction (width direction), front - rear direction (depth direction), and up - down direction (height direction) are specified based on the direction of viewing this front. Also, the representations in each figure are merely schematic, and the sizes and shapes of parts and members are appropriately deformed for ease of understanding or to avoid complication of the drawings.

[0015] This storage repository 1 basically includes an outer box 2 enclosing a storage space 11 with a uniform cross - section in the up - down direction, a plurality of inner boxes 3 (3A, 3B, 3C) stored in the storage space 11 in a stacked state in the up - down direction, a door 4 attached to the outer box 2 so as to be able to open the front of the storage space 11, an inner box retainer 5 provided on the side plates of the outer box 2 to support the inner box 3 at a predetermined height, a movable shelf board 6 installed at the bottom of the outer box 2 and held so as to be able to move up and down, and a non - electric pushing - up means for raising the movable shelf board 6 to the height of the inner box retainer 5.

[0016] The outer box 2 of the exemplary embodiment is configured by connecting a bottom plate 21, a top plate 22, left and right side plates 23, 23, and a back plate 24, and a substantially rectangular - parallelepiped - shaped storage space 11 is formed inside it. However, in this invention, the material of the plate material constituting each surface of the outer box 2, the shape and design of each surface, the joining structure between the plate materials, etc. are not particularly limited. The door 4 attached to the outer box 2 assumes a double - opening double - leaf door in the exemplary embodiment, but as long as it can open substantially the entire front of the outer box 2, a single - opening or folding - door type can also be used.

[0017] There are a plurality (three in the exemplary embodiment) of inner boxes 3 that have the same shape and dimensions, are not connected to each other, are individually independent, and can be stacked interchangeably. The material and shape of the inner box 3 can be arbitrary as long as they are suitable for stacking and long-term storage. Regarding the depth of the inner box 3, shallow types and deep types can be mixed within the range that can be accommodated in the storage space 11.

[0018] The lowermost inner box 3C is placed on the movable shelf board 6, pushed up by the rising of the movable shelf board 6, and when it reaches a predetermined height, it is supported by the inner box stopper 5 installed at that position. The inner box stopper 5 is attached, for example, at a total of four locations, two locations each in the front and rear of the left and right side plates 23 of the outer box 2. Each inner box stopper 5 is configured to be deformable into both a receiving form in which it protrudes from the side plate 23 into the storage space 11 to support the inner box 3 and a floating form in which it retracts to the side plate 23 side by being pushed up from below to allow the inner box 3 to rise.

[0019] The inner box stopper 5 shown in FIG. 6(a) includes a movable inner box support piece 51 attached to the side plate 23 via a spring hinge 52. The form in which this inner box support piece 51 protrudes horizontally by the biasing force of the spring hinge 52 to support the load of the inner box 3 is the receiving form. To supplement the supporting force at this time, a support material 53 that supports the lower surface of the inner box support piece 51 is also attached to the side plate 23. When the inner box 3 rising from below abuts against the lower surface of the horizontally protruding inner box support piece 51, the inner box support piece 51 is bounced up along the side plate 23, and it becomes the floating form. In this floating form, the opposing interval between the left and right inner box support pieces 51 is slightly larger than the lateral width of the inner box 3.

[0020] FIG. 6(b) shows another configuration example of the inner box retainer 5. This inner box retainer 5 is provided with a latch bolt-shaped inner box support piece 54 that protrudes in and out of the storage space 11 from the side plate 23 side. This inner box support piece 54 is assembled together with a spring member 56 in a case 55 attached to the side plate 23 and is held so as to be slidable in the width direction. The form in which the inner box support piece 54 protrudes into the storage space 11 by the biasing force of the spring member 56 or the like and supports the load of the inner box 3 is the receiving form. An inclined surface 57 for releasing the pressing force from below is formed at the tip of the inner box support piece 54. When the inner box 3 rising from below abuts against the inclined surface 57, the inner box support piece 54 is pushed outward and immersed in the case 55, and this becomes the floating form.

[0021] In addition, in both of the two examples shown in FIGS. 6(a) and (b), the inner box support pieces 51 and 54 engage with the bottom surface of the inner box 3 to support the inner box 3. However, appropriate engaging recesses or the like may be formed on the side surface of the inner box 3, and the inner box support pieces 51 and 54 may be engaged therewith.

[0022] The movable shelf board 6 is made of a substantially flat plate material, and its lateral width is formed to be slightly smaller than the opposing interval in the receiving form of the left and right inner box retainers 5. The movable shelf board 6 is supported on the bottom plate 21 of the outer box 2 via compression coil springs 7 attached near the four corners of its lower surface, and is biased upward by the elasticity of the compression coil springs 7. In the illustrated embodiment, this compression coil spring 7 constitutes a non-electric pushing-up means. In addition, the movable shelf board 6 can also be supported via a compression coil spring 7 on a member (not shown) that protrudes into the storage space 11 from the side plate 23 of the outer box 2, for example. When it is desired to avoid the compression coil spring 7 being exposed on the front side when the door 4 is opened, the lower side of the movable shelf board 6 may be hidden by, for example, a cloth cover material (not shown). Further, instead of such a coil spring, a constant load spring or other spring members of appropriate forms can also be used as the pushing-up means. Also, not limited to spring members, for example, a conventionally known mechanism that physically lifts (or pulls up from above) the movable shelf board 6 to a predetermined height by a manual lever, winch, or the like can also be adopted.

[0023] The basic usage method of the reserve storage 1 configured as described above is as follows. Figure 1 shows the normal reserve state with the door 4 closed. In this reserve state, the lowermost inner box 3C in the stacked inner boxes 3 is supported on the inner box retainer 5. At this time, the movable shelf board 6 is pushed up by the biasing force of the compression coil spring 7 to near the inner box retainer 5. However, in this reserve state, it does not particularly matter if the movable shelf board 6 does not contact the bottom surface of the lowermost inner box 3C.

[0024] Figure 2 shows the state where the door 4 is opened from the state of Figure 1 and the uppermost inner box 3A is taken out. Even in this state, the support form of the inner boxes 3B and 3C below the second stage and the position of the movable shelf board 6 do not particularly change, and the lowermost inner box 3C remains supported on the inner box retainer 5. In this way, the articles in the inner box 3A taken out from the uppermost stage can be consumed as appropriate. Even if the door 4 is closed again while the uppermost inner box 3A is being taken out, the support form of the inner boxes 3B and 3C and the position of the movable shelf board 6 are maintained without change. Therefore, if only a small amount of the articles stored in the uppermost inner box 3A are consumed and no replenishment is made, the door 4 can be opened and the inner box 3 can be returned to the uppermost stage again.

[0025] Figures 3 and 5 show the state where the articles stored in the inner box 3A taken out from the uppermost stage are consumed, new articles are replenished, and then re-stored at the lowermost stage. When re-storing, the movable shelf board 6 is pushed down against the biasing force of the compression coil spring 7 to near the bottom plate 21 of the outer box 2. Then, a replenishment space 12 having a height of more than one inner box is formed between the movable shelf board 6 and the inner box retainer 5. In other words, the installation position of the inner box retainer 5 is set to a height at which a replenishment space 12 of more than one inner box is formed when the movable shelf board 6 is pushed down. To facilitate the pushing down of the movable shelf board 6, the movable shelf board 6 is formed such that its depth is larger than the depth of the inner box 3, and its front edge portion is assembled to protrude forward from the inner box 3. The inner box 3A replenished with new articles is re-stored in the replenishment space 12 thus formed.

[0026] After the inner box 3A is re-stored in the replenishment space 12, when the force pressing down the movable shelf board 6 is removed, the movable shelf board 6 rises by the biasing force of the compression coil spring 7. The movable shelf board 6 stacks the re-stored inner box 3A under the upper inner boxes 3B and 3C supported by the inner box retainer 5, and as shown in FIG. 4, lifts up a row of those multiple inner boxes 3B, 3C, and 3A together. Then, the re-stored inner box 3A will be newly supported on the inner box retainer 5.

[0027] However, if the inner box 3A re-stored on the movable shelf board 6 suddenly rises when the door 4 is open and the user is in front, it is somewhat dangerous. Therefore, in the exemplary embodiment, in order to prevent the inner box 3A from rising rapidly from the states shown in FIGS. 3 and 5, a rising regulator 8 is provided to temporarily regulate the rising of the inner box 3A in conjunction with the opening and closing of the door 4. The rising regulator 8 in the exemplary embodiment is attached at least one position on the left and right at a position slightly below the inner box retainer 5 at the upper part of the replenishment space 12, or at a position slightly shifted in the front-rear direction at substantially the same height as the inner box retainer 5.

[0028] FIG. 7 shows a configuration example of the rising regulator 8. The exemplary rising regulator 8 includes a regulating piece 81 that is attached to the side plate 23 side and slides in the width direction of the replenishment space 12 and is substantially T-shaped in top view. The base of this regulating piece 81 is inserted into a guide hole portion 82 provided in the side plate 23. An urging member composed of a compression coil spring 83 or the like is incorporated in the guide hole portion 82 to push the regulating piece 81 out into the replenishment space 12. When this regulating piece 81 protrudes into the replenishment space 12, it interferes with the top surface of the re-stored inner box 3A, and the rising of the inner box 3A is regulated.

[0029] On the other hand, on the back surface of the door 4, an engaging member 84 is attached that abuts against the regulating piece 81 and retracts the regulating piece 81 outward when the door 4 is closed. The exemplary engaging member 84 is substantially L-shaped in top view, its short piece is joined to the door 4, and its long piece protrudes toward the back side. When the door 4 is closed, it abuts against the inner side surface of the regulating piece 81 and retracts the regulating piece 81 to the side plate 23 side.

[0030] Note that the regulating plate 81 constituting the rising regulator 8 is not limited to the substantially T-shaped view from above as illustrated, and can adopt, for example, a substantially L-shaped view from above or other appropriate shapes, as long as it can protrude into the replenishment space 12 and interfere with the top surface of the inner box 3A. Also, the engaging member 84 is not limited to the substantially L-shaped view from above as illustrated, and can have an appropriate shape according to the shape of the regulating plate 81.

[0031] When such a rising regulator 8 is provided at the upper part of the replenishment space 12, in the state of FIG. 3 where the inner box 3A is re-stored on the pushed-down movable shelf board 6, even if the force pushing down the movable shelf board 6 is removed, the re-stored inner box 3A will not rise suddenly, so the safety is improved. And when the door 4 is closed, the engaging member 84 pushes the regulating plate 81 into the side plate 23 side, and the interference between the regulating plate 81 and the inner box 3A disappears. Then, as shown in FIG. 4, the stacked inner boxes 3B, 3C, 3A are lifted together by one step and return to the storage state shown in FIG. 1.

[0032] Furthermore, in the exemplary embodiment, when the stacked inner boxes 3 are lifted together, a second rising regulator 9 that operates in conjunction with the opening and closing of the door 4 is provided at the upper part of the storage space 11 so that the uppermost inner box 3 is held at an appropriate height. The second rising regulator 9 is constituted by, for example, a plate piece or the like with an appropriate shape attached to the upper part of the back surface of the door 4 as shown in FIG. 8. And when the door 4 is closed, this second rising regulator 9 protrudes above the inner box 3 and engages with the top surface of the uppermost inner box 3B, and when the door 4 is opened, it disengages forward of the storage space 11 together with the door 4. Thereby, for example, when the top surface of the outer box 2 is open and another storage cabinet or the like is placed above it, or when the weight of the articles stored in the inner box 3 is small and the inner box 3 is lifted excessively, etc., it is possible to appropriately hold the height of the uppermost inner box 3.

[0033] As described above, when the uppermost inner box 3 is taken out and the old items are consumed, the position of the inner box 3 is switched by replenishing the inner box 3 with new items and then re-storing it at the lowermost position, so that the "first-in, first-out" of the stored items can be realized without difficulty. The switching method of taking out from the upper layer and replenishing the lower layer is easy for general users to grasp the storage status of the items, and it is convenient to use with less physical burden when taking in and out the items. Therefore, it is particularly convenient for users with limited strength. Needless to say, not only when re-storing the taken-out uppermost inner box 3, but also inner boxes having substantially the same height dimension can be appropriately stored.

[0034] For the movement of the stacked inner boxes 3, for example, a pushing means that does not depend on electric power, such as a spring member, is adopted, so that it can be used without trouble even in the event of a power outage due to a disaster or the like. In addition, since a complicated drive mechanism or the like is not used, it is compact and easy to secure a storage capacity. Therefore, it can be installed at low cost in both individual houses and apartment houses, and maintenance is also easy.

[0035] Thus, it is possible to periodically check the storage status of the items, consume the old items in order, eliminate wasteful disposal, etc., and obtain an efficient and economical storage environment in which the stored items can be used with confidence in the event of a disaster.

[0036] Moreover, the present invention is not limited to the form in which the outer box is independent as a single unit as described above. For example, it can also be implemented in a form in which a plurality of outer boxes are connected in the left - right direction or the up - down direction, or in a form in which the outer box is incorporated as a part of pre - assembled furniture such as a system kitchen, a pantry rack, or a living board. Such a form can be specified as a reserve storage structure comprising: a storage space that is continuous in the up - down direction; a plurality of inner boxes that are stacked in a state of being independent of each other without being connected to each other and are stored in the storage space; a door for opening and closing the storage space; an inner box receiver installed on a side wall of an appropriate shape surrounding the storage space (corresponding to the "side plate" in the above - mentioned embodiment) to support the inner box at a predetermined height; a movable shelf board installed on the bottom plate or the side wall below the inner box receiver and held so as to be movable up and down; and a non - electric pushing - up means for raising the movable shelf board to the height of the inner box receiver. Also in this reserve storage structure, the inner box receiver is configured to be deformable into both a receiving form that protrudes from the side wall into the storage space and engages with the bottom surface or side surface of the inner box, and a floating form that retracts laterally by being pushed up from below to allow the inner box to rise. When the door is closed, the lowermost inner box is supported by the inner box receiver. When the door is opened, the uppermost inner box is taken out, and when the movable shelf board is pushed down against the pushing - up means, the state where the inner boxes below the second stage are supported by the inner box receiver is maintained, and a replenishment space having a height of at least one inner box is formed between the movable shelf board and the inner box receiver so that it can be re - stored. When the pushing - up means is activated with an inner box re - stored in the replenishment space, the movable shelf board rises, and the re - stored inner box overlaps the lower side of the inner box supported by the inner box receiver, and the plurality of inner boxes are lifted together by one stage, so that the re - stored inner box can be configured to be supported by the inner box receiver.

A storage space that is continuous in the vertical direction, A plurality of inner boxes that are stacked in a state where they are not connected to each other and are individually independent and stored in the storage space, A door that opens and closes the storage space, An inner box receiving tool installed on the side wall surrounding the storage space to support the inner box at a predetermined height, A movable shelf board that is held so as to be able to move up and down below the inner box receiving tool, A non-electric pushing-up means for raising the movable shelf board to the height of the inner box receiving tool, Comprising, The inner box receiving tool is configured to be deformable into both a receiving form that protrudes from the side wall into the storage space and engages with the bottom surface or side surface of the inner box, and a floating form that retreats laterally by being pushed up from below and allows the inner box to rise. When the door is closed, the lowermost inner box is supported by the inner box receiving tool. When the door is opened and the uppermost inner box is taken out, and the movable shelf board is pushed down against the pushing-up means, the inner boxes below the second stage are maintained in a state of being supported by the inner box receiving tool, and a replenishment space having a height of at least one inner box is formed between the movable shelf board and the inner box receiving tool, enabling re-storage. When the pushing-up means is activated with an inner box re-stored in the replenishment space, the movable shelf board rises, and the re-stored inner box overlaps the lower side of the inner box supported by the inner box receiving tool, and the plurality of inner boxes are lifted together by one stage, so that the re-stored inner box is supported by the inner box receiving tool. A storage structure configured as described above.
