Description

[Technical Field]

[0001] The present invention relates to a storage device. [Background technology]

[0002] Techniques for storing items have already been developed, and the technique described in Patent Document 1 is one example. The storage shelf described in Patent Document 1 includes shelf rails that are installed on a wall and extend in the vertical direction, and shelf boards on which stored items are placed. The shelf rails have multiple locking holes formed along the vertical direction, and the shelf boards are engaged with the locking holes via bracket members. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Publication No. 2023-58227 Summary of the Invention [Problem to be solved by the invention]

[0004] In a storage device such as the storage shelf described in Patent Document 1, the load capacity of the stored items is determined in advance, and the user needs to store the items taking the load capacity into consideration. However, the load capacity is generally not directly written on the storage device, but is often written in, for example, an instruction manual that comes with the storage device. Therefore, when a user wants to check the load capacity of a storage device, they have to take out the instruction manual and check the load capacity, which is time-consuming. Furthermore, even if the load capacity of a storage device is known, it is not easy to determine the actual weight of the stored items. This is fine if the load of the stored items is clearly below the load capacity, but if the load of the stored items is assumed to be close to the load capacity, it is necessary to accurately determine the load of the stored items, which is time-consuming. If a storage device is used without determining the load of the stored items, there is a risk that the load of the stored items will exceed the load capacity, and it is not recommended to use the storage device in such a state.

[0005] Therefore, the present invention was made in consideration of the above-mentioned problems, and its purpose is to provide a storage device that allows visual confirmation that the stored items have exceeded the load capacity. [Means for solving the problem]

[0006] The above object is achieved by a storage device of the present invention, which comprises a base portion having a fixed portion fixed to a wall surface, a movable portion located below the fixed portion, and a spring member connecting the fixed portion and the movable portion and resisting downward movement of the movable portion relative to the fixed portion, and a movable member that engages with a support that supports the stored items and moves vertically together with the movable portion, wherein the fixed portion can protrude from the upper end of the movable member, and the amount of protrusion of the fixed portion relative to the upper end of the movable member changes as the vertical position of the movable member changes depending on the load of the stored items.

[0007] In the storage device of the present invention, the vertical position of the movable member changes in response to the load of the stored items, thereby changing the amount of protrusion of the fixed part from the upper end of the movable member. This allows the user to visually confirm that the stored items have exceeded the load capacity by checking the change in the amount of protrusion.

[0008] In addition, when the stored items exceed the load capacity, the fixed portion may protrude from the upper end of the moving member. With the above configuration, the user can visually confirm that the stored items have exceeded the withstand load simply by checking whether or not the fixing part is protruding.

[0009] In addition, a first display unit may be provided on the fixed portion that protrudes from the upper end of the movable member when the load of the stored items exceeds a first threshold value, to indicate that the load of the stored items has exceeded the first threshold value. With the above configuration, the user can easily confirm that the stored items have exceeded the withstand load by looking at the first display section.

[0010] Furthermore, a second indicator may be provided on the fixed part below the first indicator to indicate that the load of the stored items has exceeded a second threshold value that is larger than the first threshold value. With the above configuration, the level of excess load relative to the withstand load can be checked in stages using the first display section and the second display section.

[0011] In addition, the storage device of the present invention may include a plurality of base parts arranged at intervals in the vertical direction as base parts, and the movable parts of each of the plurality of base parts may be fixed to a common movable member, and the fixed part of the base part located at the top of the plurality of base parts may be capable of protruding from the upper end of the common movable member. With the above configuration, the user can visually confirm that the stored items have exceeded the load capacity by checking the change in the amount of protrusion of the fixing part located at the top.

[0012] In addition, the storage device of the present invention may include, as base portions, a plurality of base portions arranged at different positions in a direction intersecting the vertical direction, and as movable members, a plurality of movable members arranged corresponding to the plurality of base portions, and the fixed portions of the plurality of base portions may each be capable of protruding from the upper ends of the corresponding movable members. With the above configuration, it is possible to appropriately confirm whether the stored item has exceeded the load capacity, regardless of the position of the center of gravity of the stored item.

[0013] The movable member may also have a first plate portion fixed to the movable portion from the side opposite the wall surface, a second plate portion protruding from the end of the first plate portion in the second direction toward the movable portion, when the direction in which the movable portion and the first plate portion are aligned is defined as the first direction and the direction intersecting both the vertical direction and the first direction is defined as the second direction, and an engaging portion provided on the second plate portion that engages with an engaged portion provided on the movable portion. With the above configuration, the moving member is fixed to the movable portion from the first direction and engages with the movable portion from the second direction, so that the moving member can be appropriately attached to the movable portion. [Effects of the Invention]

[0014] According to the present invention, it is possible to provide a storage device that allows visual confirmation that the stored items have exceeded the withstand load. [Brief explanation of the drawings]

FIG. DETAILED DESCRIPTION OF THE INVENTION

[0016] One embodiment of the present invention (hereinafter referred to as the present embodiment) will be described in detail below with reference to a preferred embodiment shown in the accompanying drawings. Note that the following embodiment is merely an example given to facilitate understanding of the present invention and is not intended to limit the present invention. In other words, the configuration of the present invention may be modified or improved from the following embodiment without departing from the spirit of the present invention. In addition, the drawings show each component somewhat simplified and schematic to make the explanation easier to understand, and the size (dimensions) of each component and the spacing between components shown in the drawings may differ from the actual ones. Furthermore, unless otherwise specified, the material and shape of each member used to implement the present invention can be set arbitrarily depending on the application of the present invention and the state of the art at the time of implementing the present invention. Furthermore, "orthogonal," "vertical," and "horizontal" include the range of error generally accepted in the technical field of the present invention, and also include states where they deviate within a range of several degrees (e.g., 5° to 10°) from the strict "orthogonal," "vertical," and "horizontal."

[0017] In addition, in this specification, three mutually orthogonal directions are referred to as the "up-down direction," the "first direction," and the "second direction," as shown in FIG. 1. The "up-down direction" corresponds to the vertical direction or the height direction. The "first direction" and the "second direction" correspond to the horizontal direction. More specifically, the "first direction" corresponds to the left-right direction (width direction) of a storage space S (described later) whose front side (front face side) is open, as shown in FIG. 1, and also corresponds to the direction in which a first plate portion 31 and a movable portion 22 (described later) are aligned, as shown in FIG. 3. The "second direction" corresponds to the front-to-back direction (depth direction) of the storage space S, as shown in FIG. 1. In the following description, unless otherwise specified, the "first direction" will be referred to as the "left-right direction" and the "second direction" will be referred to as the "front-rear direction." In the following description, unless otherwise specified, the "left side" and "right side" refer to the left side and right side when the storage space S is viewed from the front.

[0018] <<Overview of the storage device according to this embodiment>> A storage device according to this embodiment (hereinafter referred to as storage device 10) will be described with reference to FIGS. As shown in FIG. 1, the storage device 10 is used, for example, to efficiently store items (not shown) in the storage space S and is installed in the storage space S. An example of the storage device 10 is a storage shelf. An example of the storage space S is a closet installed in a building such as a house. In the example shown in FIG. 1, the storage space S is a space open to the front and surrounded by a top surface C, a floor surface F, a left wall surface W1, a right wall surface W2, and a rear wall surface W3. The top surface C and the floor surface F are spaced apart in the vertical direction. The left wall surface W1 and the right wall surface W2 are located between the top surface C and the floor surface F and spaced apart in the horizontal direction. The left wall surface W1 is the wall located on the left side of the storage space S when viewed from the front, and the right wall surface W2 is the wall located on the right side of the storage space S when viewed from the front. The rear wall surface W3 is the wall located on the rear side of the storage space S in the front-to-rear direction.

[0019] In the example shown in Fig. 1, the storage device 10 is installed across both the left and right wall surfaces (left wall surface W1 and right wall surface W2) of the storage space S. The storage device 10 has a plurality of supports 40 (described later) (three in Fig. 1) arranged in the vertical direction, and by placing items to be stored on the supports 40, the items can be efficiently stored in the vertical direction. When items are stored in the storage device 10, a movable member 30 (described later) moves downward in accordance with the load of the items. When the load of the items exceeds the withstand load, a fixed portion 21 (described later) of a base portion 20 protrudes from an upper end 30a (see FIG. 5) of the movable member 30. By checking the change in the amount of protrusion of the fixed portion 21, the user can visually confirm that the items have exceeded the withstand load. Note that the "load of stored items" referred to here corresponds to the total load of all stored items supported by multiple (three in Figure 1) supports 40, that is, the total load of all stored items stored in the storage device 10. Furthermore, the "load capacity" referred to here corresponds to a value calculated by multiplying the actual load capacity by a safety factor. Therefore, even if the stored items exceed the load capacity, it will not immediately cause a malfunction in the storage device 10. However, from a long-term perspective, since there is a possibility of malfunction, if the stored items exceed the load capacity, it can be said that this is a load that requires a warning to the user to reduce the amount of stored items.

[0020] In the above description, the storage device 10 is installed across both the left and right walls of the storage space S (left wall W1 and right wall W2), but this is not limited to this and it may be fixed to, for example, the rear wall W3. Furthermore, although the storage device 10 is described as being installed in a storage space S within a building, this is not limited to this, and it may be installed, for example, on a wall surface of another space within the building (e.g., a living space), on a wall surface outside the building (outdoors), or on a wall surface of a structure other than a building.

[0021] <<Configuration of the storage device according to this embodiment>> As shown in FIG. 1, the storage device 10 includes a plurality of base portions 20 (eight in FIG. 1), a plurality of movable members 30 (four in FIG. 1), and a plurality of support bodies 40 (three in FIG. 1). The eight base portions 20 are arranged at different positions in directions intersecting the up-down direction, i.e., in the left-right and front-rear directions, and in this embodiment, two are arranged at each of four points. The two base portions 20 arranged at each point are spaced apart in the up-down direction. The four moving members 30 are arranged corresponding to the eight base portions 20, and in this embodiment, they are arranged at four points, just like the base portions 20. The three supports 40 are arranged spaced apart in the up-down direction. In this embodiment, the supports 40 are supported on both sides in the left-right direction and also in the front-rear direction by the four moving members 30. The numbers of base units 20, movable members 30, and supports 40 described above are merely examples, and the numbers are arbitrary and may be one or a plurality of numbers other than those mentioned above. For example, the base units 20 and movable members 30 may be arranged at only one point, and the support 40 may be supported on one side in the left-right or front-back direction by the movable member 30 arranged at that one point.

[0022] In the following explanation, unless otherwise specified, we will explain the base unit 20 and movable member 30 at one of the four points mentioned above, specifically the base unit 20 and movable member 30 located in front of the left wall W1, but the same applies to the base unit 20 and movable member 30 located at the other three points.

[0023] <Base part> As shown in FIG. 3, the base portion 20 has a fixed portion 21, a movable portion 22, and a spring member 23.

[0024] The fixing portion 21 is a member formed of a material such as resin or metal, and in this embodiment, as shown in Fig. 3, is in the form of, for example, a rectangular parallelepiped block, and is fixed to the left wall W1 with a fastener (screw, etc.) not shown. The shape of the fixing portion 21 is not particularly limited, and for example, the shape of a cross section perpendicular to the up-down direction may be rectangular, circular, elliptical, quadrangle other than a rectangle, polygon other than a quadrangle, or irregular, etc.

[0025] Here, among the multiple base parts 20 positioned apart in the vertical direction, the fixed part 21 of the uppermost base part 20 is provided with a first display part 24 and a second display part 25 as shown in FIG.

[0026] 5, the first display unit 24 is provided on a portion of the fixed part 21 that protrudes from the upper end 30a of the movable member 30 when the load of the stored items exceeds a first threshold (load capacity) (hereinafter referred to as the upper part 21a), and indicates that the load of the stored items has exceeded the first threshold. The upper part 21a corresponds to a portion of the fixed part 21 that is above the center position of the fixed part 21 in the up-down direction. The first display portion 24 may be, for example, a specific pattern, shape, character, color, or marker provided on the surface of the upper portion 21a. The "first threshold" may be a load capacity, for example, a load at a caution level. The first display unit 24 is preferably provided at least on the front side in the front-to-rear direction of the upper portion 21a (fixed portion 21). This allows the user to easily visually confirm the first display unit 24 from the front (front side) of the storage space S.

[0027] The second indicator 25 indicates that the load of the stored items has exceeded a second threshold value that is larger than the first threshold value. The second indicator 25 is provided on the fixed part 21 below the first indicator 24, and as shown in Fig. 6, is provided on a portion of the fixed part 21 that protrudes from the upper end 30a of the movable member 30 when the load of the stored items has exceeded the second threshold value (hereinafter referred to as the lower part 21b). The lower part 21b corresponds to a portion of the fixed part 21 that is below the center position of the fixed part 21 in the up-down direction. The second display portion 25 is provided, for example, on the surface of the lower portion 21b, and may be a specific pattern, shape, character, color, or marker that is different from the first display portion 24. The "second threshold" may be a load at a warning level that exceeds the load capacity and requires even more caution than the caution level. The second display unit 25 is preferably provided at least on the front side in the front-to-rear direction of the lower portion 21b (fixed portion 21). This allows the user to easily visually check the second display unit 25 from the front (front side) of the storage space S.

[0028] In the above description, the first display unit 24 and the second display unit 25 are provided on the fixed part 21 of the base unit 20 located at the top, but this is not limiting and they may be provided on the fixed part 21 of another base unit 20 (for example, the base unit 20 located at the bottom in FIG. 3). For example, if the first display unit 24 and the second display unit 25 are provided on the fixed part 21 of all the base units 20, the number of types of base units 20 will be reduced, and the management burden of the base units 20 (and further the storage devices 10) can be reduced at each stage of design, assembly (production), and shipping.

[0029] As shown in Fig. 3, the movable part 22 is located below the fixed part 21 and is a member made of, for example, a material such as resin or metal, and in this embodiment, is in the form of, for example, a rectangular parallelepiped block. The shape of the movable part 22 is not particularly limited, and the cross section perpendicular to the up-down direction may be, for example, rectangular, circular, elliptical, quadrilateral other than a rectangle, polygonal other than a rectangle, or irregular, etc. As shown in Fig. 3, the movable part 22 is located away from the left wall surface W1 in the left-right direction, and a gap is provided between the movable part 22 and the left wall surface W1. 4, an engaged portion 22a that engages with (fits into) an engaging portion 33 (described later) is provided on an end (side surface) in the front-rear direction of the movable portion 22. The shape of the engaged portion 22a is not particularly limited as long as it corresponds to the shape of the engaging portion 33, and in this embodiment, it is a concave groove. In this embodiment, the movable part 22 has two engaged parts 22a, one of which is provided at the front end of the movable part 22 in the front-to-rear direction, and the other engaged part 22a is provided at the rear end of the movable part 22 in the front-to-rear direction.

[0030] The spring member 23 connects the fixed part 21 and the movable part 22, and resists downward movement of the movable part 22 relative to the fixed part 21. In other words, when the movable part 22 moves away from the fixed part 21, a force acts on the movable part 22 to return it to its original position. The spring member 23 is located between the fixed part 21 and the movable part 22 in the vertical direction, and the upper end of the spring member 23 is attached to the lower end of the fixed part 21, and the lower end of the spring member 23 is attached to the upper end of the movable part 22. The spring constant of the spring member 23 is set (adjusted) so that, as shown in Fig. 5, when the load of the stored item exceeds a first threshold, the first display part 24 protrudes from the upper end 30a of the movable member 30, and, as shown in Fig. 6, when the load of the stored item exceeds a second threshold, the second display part 25 protrudes from the upper end 30a of the movable member 30.

[0031] <Moving parts> The moving member 30 engages with a support 40 that supports stored items as shown in FIG. 1, and moves vertically together with the movable part 22 as shown in FIGS. When an item is placed on the support 40, the weight of the item causes the movable part 22, the moving member 30, and the support 40 to move downward as a unit against the spring member 23 attached to the movable part 22. Conversely, when the item is removed from the support 40, the movable part 22, the moving member 30, and the support 40 move upward as a unit due to the force of the spring member 23 attached to the movable part 22.

[0032] The movable member 30 is a member that extends in the vertical direction and is positioned away from the top surface C and the floor surface F in the vertical direction. The movable member 30 is, for example, a cylindrical rail (a square cylindrical rail in FIG. 2) that is open at both ends in the vertical direction. Furthermore, as shown in FIG. 2, the movable member 30 is open at the end (left end) on the left wall surface W1 side in the horizontal direction, and a part of the base portion 20 extends into the movable member 30 from the open end on the left wall surface W1 side. In other words, when viewed from the vertical direction, the movable member 30 surrounds the outside of the base portion 20 except for the left wall surface W1 side.

[0033] As shown in Figure 3, the movable parts 22 of two base parts 20 arranged at a distance from each other in the vertical direction are fixed to a common movable member 30, and the fixed part 21 of the base part 20 located at the top of the two base parts 20 can protrude from the upper end 30a of the movable member 30. In addition, in this embodiment, as shown in Figure 1, the base portion 20 and the movable member 30 are respectively arranged at four points, and at each point, the fixed portion 21 of the base portion 20 located at the top can protrude from the upper end 30a of the corresponding movable member 30.

[0034] As shown in FIG. 4, the moving member 30 has a first plate portion 31, two second plate portions 32, and two engagement portions 33.

[0035] The first plate portion 31 is a plate extending in the vertical direction and has, for example, a rectangular shape. The first plate portion 31 is fixed to the movable portion 22 from the side opposite the left wall surface W1 in the left-right direction, and is fixed to the movable portion 22 by, for example, a fastener (screw or the like) not shown. Note that while the first plate portion 31 is fixed to the movable portion 22, it is not fixed to the fixed portion 21, and a gap is provided between the first plate portion 31 and the fixed portion 21 in the left-right direction. As shown in Figure 3, the first plate portion 31 has a plurality of holes 31a arranged at intervals in the vertical direction, and any one of the plurality of holes 31a (or a hole 31a selected by the user) is engaged with the left-right end of the support body 40 described below.

[0036] 4, the second plate portion 32 protrudes from the front-rear end of the first plate portion 31 toward the movable portion 22 in the left-right direction, and is adjacent to the movable portion 22 in the front-rear direction. The second plate portion 32 is a plate that extends in the up-down direction and has, for example, a rectangular shape. In this embodiment, of the two second plate portions 32, one second plate portion 32 protrudes from the front end portion of the first plate portion 31 in the fore-and-aft direction, and the other second plate portion 32 protrudes from the rear end portion of the first plate portion 31 in the fore-and-aft direction.

[0037] 4, the engaging portion 33 is provided on the second plate portion 32, specifically, on the end of the second plate portion 32 opposite to the first plate portion 31 in the left-right direction, and engages (fits) with the engaged portion 22a provided on the movable portion 22. The shape of the engaging portion 33 is not particularly limited as long as it corresponds to the shape of the engaged portion 22a, and in this embodiment, the engaging portion 33 forms a convex protrusion corresponding to the concave engaged portion 22a. For example, unlike this embodiment, if the engaged portion 22a is convex, the engaging portion 33 may be a concave groove.

[0038] <Support> The support body 40 supports the stored items and is, for example, a flat rectangular plate (shelf board) on which the stored items are placed to support the stored items. The left and right ends of the support body 40 are engageable with a plurality of holes 31a provided in the first plate portion 31, and the support body 40 engages with any of the plurality of holes 31a (or a hole 31a selected by the user).

[0039] <<Operations and Effects of the Storage Device According to the Present Embodiment>> 3, when the support body 40 is not supporting an item to be stored, the upper end 21c of the fixed part 21 is positioned lower than the upper end 30a of the movable member 30. On the other hand, when the support body 40 supports an item to be stored, the load of the item causes the movable member 30 to move downward against the spring member 23. Then, when the load of the item to be stored further increases and the item to be stored reaches the withstand load (first threshold), the upper end 21c of the fixed part 21 is positioned at the same height as the upper end 30a of the movable member 30. Furthermore, when the load of the stored items exceeds the withstand load (first threshold), the upper portion 21a of the fixed part 21 protrudes from the upper end 30a of the movable member 30, as shown in Fig. 5. This makes the first display unit 24 provided on the upper portion 21a visible. Then, when the load of the stored items further increases and exceeds the second threshold, the lower portion 21b of the fixed part 21 protrudes from the upper end 30a of the movable member 30, as shown in Fig. 6. This makes the second display part 25 provided on the lower portion 21b visible.

[0040] In this way, in the storage device 10, the vertical position of the movable member 30 changes depending on the load of the stored items, thereby changing the amount of protrusion of the fixed part 21 from the upper end 30a of the movable member 30. This allows the user to visually confirm that the stored items have exceeded the withstand load by checking the change in the amount of protrusion.

[0041] Furthermore, in the storage device 10, when the stored item exceeds the withstand load (first threshold), the fixed part 21 protrudes from the upper end 30a of the movable member 30. This allows the user to visually confirm that the stored item has exceeded the withstand load by the simple method of checking whether the fixed part 21 protrudes or not. Furthermore, a first display unit 24 is provided on the upper portion 21a of the fixed part 21. This allows the user to easily check that the stored items have exceeded the withstand load by looking at the first display unit 24. In addition, a second display unit 25 is provided on a lower portion 21b of the fixed part 21, which is located below the first display unit 24. Therefore, the first display unit 24 and the second display unit 25 allow the user to check the level of excess load relative to the withstand load in stages.

[0042] The storage device 10 also includes two base sections 20 that are spaced apart in the vertical direction, and the movable sections 22 of the two base sections are fixed to a common movable member 30. The fixed section 21 of the uppermost base section 20 of the two base sections 20 can protrude from the upper end 30a of the common movable member 30. This allows the user to visually confirm that the stored items have exceeded the load capacity by checking the change in the amount of protrusion of the uppermost fixed section 21.

[0043] Furthermore, the storage device 10 includes a plurality of base portions 20 arranged at different positions (points) in directions (left-right and front-rear directions) intersecting the up-down direction, and the fixing portions 21 of the base portions 20 at each point can protrude from the upper ends 30a of the corresponding movable members 30. This makes it possible to appropriately confirm that the stored item has exceeded its load capacity, regardless of the position of the center of gravity of the stored item. In other words, even if the position of the center of gravity of the stored item is offset in either the left-right or front-rear directions with respect to the position of the center of gravity of the support body 40 when viewed from the up-down direction, it is possible to appropriately confirm that the stored item has exceeded its load capacity by checking the change in the amount of protrusion of the fixing portions 21 at each point.

[0044] The moving member 30 has a first plate portion 31, a second plate portion 32, and an engaging portion 33. As a result, the moving member 30 is fixed to the movable part 22 from the left-right direction and engages with the movable part 22 from the front-rear direction, so that the moving member 30 can be appropriately attached to the movable part 22. For example, even if vibrations occur in the movable part 22 and the moving member 30 due to swinging of the spring member 23 when a stored item is supported on the support body 40, it is possible to prevent the moving member 30 from coming off the movable part 22.

[0045] <<Other embodiments>> In the above embodiment, when the stored item exceeds the withstand load, the fixed portion 21 protrudes from the upper end 30a of the movable member 30. However, this is not limited to this, and for example, even when the stored item is below the withstand load, the fixed portion 21 may be made to protrude from the upper end 30a of the movable member 30 in advance. In this case, the amount of protrusion when the stored item exceeds the withstand load is specified in advance, and the user can visually confirm that the stored item has exceeded the withstand load by confirming that the specified protrusion amount has been reached.

[0046] In the above embodiment, the storage device 10 is provided with a plurality of base parts 20 (two in FIG. 1) spaced apart from one another in the vertical direction, but this is not limiting and the storage device may be provided with three or more base parts 20 spaced apart from one another in the vertical direction. The storage device may also be provided with only the top-most base part 20, i.e., only one base part 20.
