Description

[Technical Field]

[0001] The present invention relates to a storage device on which articles are placed and which is attached to a shelf board, and a shelf provided with the storage device. [Background technology]

[0002] Conventionally, shelves with multiple shelves on which items can be placed have been used to store items. However, in shelves where the vertical spacing between the shelves cannot be adjusted, when low items are placed on the shelves, a space that cannot be used for storage, known as dead space, is generated. To solve this problem, various storage devices that can be attached to the shelves have been proposed.

[0003] For example, Patent Document 1 describes a storage device that has a storage basket that can be extended and retracted to the left and right and has an elastic locking strip arranged on the top, while Patent Document 2 describes a storage device that has a locking part that can be locked to a shelf board.

[0004] [Patent Document 1] Utility Model Registration No. 3231381 [Patent Document 2] Jitsuzenhei 3-089383 Publication Summary of the Invention [Problem to be solved by the invention]

[0005] However, in the storage devices described in Patent Documents 1 and 2, the storage section cannot be pulled out from the shelf board, making it difficult to store and remove items from the storage section.

[0006] The present invention has been made in consideration of the above-described circumstances, and an object of the present invention is to provide a storage device that can be pulled out from a shelf board and is easy to use, and a shelf equipped with the same. [Means for solving the problem]

[0007] In order to solve the above problem, the present invention is a storage device that is hung from a shelf, and includes a storage section for storing items and a holding section that is attached to the shelf, wherein the holding section holds the storage section so that it can slide freely in the depth direction of the shelf, and when attached to the shelf, the sliding direction of the storage section is inclined with respect to the surface of the shelf.

[0008] According to the present invention, the sliding movement of the storage section makes it easy to store and remove items from the storage section. Furthermore, since the sliding direction is inclined with respect to the bottom surface of the plate, the storage section can slide easily.

[0009] In a preferred embodiment of the present invention, the storage section has a gripping portion that is gripped by a user, and an extension line of the sliding movement intersects with a plane including the bottom surface of the shelf board at a position deeper than the shelf board. With this configuration, when the storage device is attached to the shelf, the front side is lower in the downward direction, making it easy to pull out the storage section. Furthermore, even if the storage device is attached in a high place, it can be easily grasped by the grip portion.

[0010] In a preferred form of the present invention, the storage section has an opening at its top connecting the internal space with the external space and a sliding protrusion protruding from the edge of the opening, the holding section has a support section on which the sliding protrusion is placed and is attached parallel to the bottom surface of the shelf, and the support section has an inclined surface that slopes downward toward the gripping section. With this configuration, a gap is created between the opening of the storage section and the holding section, making it easier to store and remove items from the storage section.

[0011] In a preferred embodiment of the present invention, the retaining portion has a first retaining portion component including the support portion, a second retaining portion component configured so that the length of protrusion from the first retaining portion component can be freely changed, and fixing means for fixing the length of protrusion from the first retaining portion component to the second retaining portion component at a predetermined position, the first retaining portion component and the second retaining portion component are provided with attachment portions for attachment to the shelf board, the first retaining portion component includes a leaf spring, and the fixing means is provided with a first uneven portion provided on the leaf spring and a second uneven portion provided on the second retaining portion, the leaf spring is formed so that the first uneven portion biases towards the second uneven portion, and the first uneven portion is fitted into and fixed to the second uneven portion. This configuration allows the storage device to be attached to the shelf board according to its size. Furthermore, by being firmly fixed to the shelf board, the holding part is prevented from moving when the storage part is slid. Furthermore, it is possible to maintain the tilted sliding direction.

[0012] In a preferred embodiment of the present invention, the grip portion includes a protruding portion that protrudes from the bottom surface of the storage portion. With this configuration, the storage section can be grasped from the ground surface.

[0013] In a preferred embodiment of the present invention, the protrusion extends from an edge of the bottom surface of the storage section. By adopting such a configuration, the manufacturing cost of the protrusion portion can be reduced. [Effects of the Invention]

[0014] According to the present invention, it is possible to provide a storage device that can be pulled out from a shelf board and is easy to use, and a shelf equipped with the same. [Brief explanation of the drawings]

[0016] Hereinafter, a storage device according to an embodiment of the present invention will be described with reference to FIGS. The embodiment shown below is an example of the present invention, and the present invention is not limited to the embodiment shown below. In these drawings, the symbol X indicates a storage tool according to this embodiment. Here, the front side means the side from which the user pulls out the storage device X when using it in the space where it is installed, and the back side means the side opposite the front side. The depth direction means the direction connecting the front side and the back side. The left-right direction means the left and right when viewing the storage device X from the front. The height direction means the direction perpendicular to both the depth direction and the left-right direction. The bottom surface means the surface facing the ground. In addition, the dotted lines in Figure 4 indicate horizontal lines parallel to the earth's surface.

[0017] <Configuration> As shown in Fig. 1, the storage device X includes a storage section 1 for storing items L, and a holding section 2 attached to a shelf board S (see Fig. 7) described below. The shelf board S may be, for example, a shelf board provided on a shelf in a refrigerator.

[0018] As shown in Figure 2, the storage section 1 has an opening 11 on the top surface (facing the shelf S) that connects the internal space with the external space, a handle 12 that the user holds when performing a drawer operation, and a sliding protrusion 13 that protrudes from the edge of the opening 11.

[0019] The storage unit 1 is a box having a substantially rectangular parallelepiped shape. The material of the storage unit 1 is preferably plastic, but is not particularly limited as long as it has rigidity.

[0020] The height direction length from the edge of the opening 11 to the bottom end of the grip portion 12 is set to be shorter than the length from the bottom end of the grip portion 12 to the sliding protrusion 13. The difference in length is preferably greater than the length of one of the user's fingers, for example, 1 cm to 3 cm. This makes it easy to grip the grip portion 12 from above. In addition, since a gap is created between the storage portion 1 and the holding portion 2 (see FIG. 1), it becomes possible to check the item L stored in the storage portion 1 from the outside.

[0021] As shown in FIG. 2 or FIG. 4(a), the grip portion 12 is formed on the front side of the storage portion 1, and has a grip portion main body 121 and a protruding portion 122 that protrudes from the bottom surface of the storage portion 1.

[0022] The grip body 121 is a part that is provided on the same plane as the side wall on the front side of the storage unit 1, and in this embodiment, this side wall is the grip body 121. The user can pull out the storage unit 1 by pinching the grip body 121 from above. The material of the protruding portion 122 is preferably the same as that of the storage portion 1, but is not particularly limited as long as it has rigidity.

[0023] Protruding portion 122 is a portion that extends from the bottom of grip body 121 perpendicularly to the bottom surface by approximately 1 cm to 4 cm, and is lower than the height of the main body of storage unit 1 at least to ensure space below storage unit 1. In the embodiment, protruding portion 122 extends around the edge of the bottom surface so as to surround the bottom surface of storage unit 1. This allows the user to grasp the protruding portion 122 from below and pull out the storage unit 1. This also creates a sense of unity with the shape of the grip body 121, contributing to excellent design. In addition, this also helps prevent damage to the packaging material of the storage device X and reduces the manufacturing costs of the storage device X. The material of the protruding portion 122 is preferably the same as that of the storage portion 1, but is not particularly limited as long as it has rigidity.

[0024] The sliding protrusion 13 extends outward from the opening 11, and its extension length is at least longer than the width of the support part P, which will be described later. This allows the bottom surface of the sliding protrusion 13 to be placed on and slide on the support part P of the holding part 2, which will be described later. In this embodiment, a groove adjacent to the storage part 1 is formed on the bottom surface of the sliding protrusion 13, which reduces the contact area with the support part P and makes the sliding smoother.

[0025] 3, the holding part 2 has a first holding part constituent 21, a second holding part constituent 22 configured so that the length of projection from the first holding part constituent 21 can be freely changed, and fixing means F that fixes the length of projection from the first holding part constituent 21 at a predetermined position with respect to the second holding part constituent 22. Furthermore, in the holding part 2, the surface that abuts against the shelf board S to support the lower member is used as a holding surface, and in this embodiment, the holding surface is provided horizontally with respect to the bottom surface of the shelf board S.

[0026] The first holding part constituent 21 is provided with a first mounting portion 211 that is attached to the shelf board S (see FIG. 7), an insertion portion 212 into which the second holding part constituent 22 is inserted, and a support portion P that supports the storage section 1 (see FIG. 1).

[0027] The first attachment portion 211 is a hook that is substantially L-shaped in side view, and has a first portion that protrudes from the end of the first holding part constituent 21 in the direction of the shelf board S, and a second portion that extends from the end of this vertical portion toward the inside of the first holding part constituent 21. The length of the first attachment portion 211 in the left-right direction is the same as the length of the first holding part constituent 21 in the left-right direction.

[0028] The insertion portion 212 includes a left insertion portion 212L provided at the left end of the first holding portion constituent 21 and a right insertion portion 212R provided at the right end of the first holding portion constituent 21.

[0029] The left insertion portion 212L and the right insertion portion 212R are grooves formed so that their respective cross sections are larger than the respective cross sections of the left second holding part component 22L and the right second holding part component 22R, which will be described later. This makes it possible to house and protrude the left-side second holding part constituent 22L and the right-side second holding part constituent 22R in the left-side insertion portion 212L and the right-side insertion portion 212R, respectively.

[0030] Moreover, it is preferable that the lengths in the depth direction of the left insertion portion 212L and the right insertion portion 212R are longer than the lengths in the depth direction of the left second holding part component 22L and the right second holding part component 22R, respectively. This makes it possible to store everything except the second attachment portion 221 of the left-side second holding portion component 22L and the right-side second holding portion component 22R in the left-side insertion portion 212L and the right-side insertion portion 212R, respectively, and therefore makes it possible to store the storage tool X compactly when not in use.

[0031] The left insertion portion 212L and the right insertion portion 212R are open at the bottom, and are provided with windows W that communicate with the top surface of the first holding portion component 21 (in the direction facing the shelf board S). This contributes to excellent maintainability by facilitating the position adjustment of the second holding part constituent 22 and facilitating the removal of dust and the like that has become mixed into the insertion part 212. Furthermore, the first holding part constituent 21 is lightweight, which makes it easy to attach it to the shelf board S (see FIG. 7).

[0032] As shown in Figure 3 or Figure 4(b), the support part P includes a top surface (facing the shelf board S) that is a flat surface on which a portion of one sliding protrusion 13 can be placed, and the top surface of the support part P is provided in each insertion part 212 in a state in which it slopes downward toward the front side. In this embodiment, the support portion P is provided in the depth direction relative to one slide protrusion 13, and the top surface of one support portion P is arranged so as to be on approximately the same plane as the top surfaces of the other support portions P. This makes it possible to hold the storage unit 1. In addition, the extension line of the sliding direction of the storage unit 1 intersects with the surface including the bottom surface (or holding surface) of the shelf board S on the back side of the shelf board S, so an inclination occurs toward the front side with respect to the bottom surface of the shelf board S, allowing for smooth sliding.

[0033] Preferably, a plurality of support portions P are provided at regular intervals in the depth direction. This reduces the contact area with the sliding protrusion 13, reducing friction and enabling smoother sliding.

[0034] The number of support parts P is not particularly limited as long as each support part P can hold one sliding protrusion 13 and allow one sliding protrusion 13 to slide. The top surface may be bent toward the shelf board S, thereby reducing the contact area with the sliding protrusion 13 and reducing friction, allowing for smoother sliding.

[0035] The inclination of the top surface of the support part P is preferably between 0.1° and 5°, and the inclination of the bottom surface is preferably reduced to prevent stored items from tipping over, and more preferably between 0.3° and 1.0°. In this embodiment, the inclination angle is 0.5°.

[0036] Some of the support parts P are provided with support protrusions P1 that protrude toward the top surface. More specifically, in this embodiment, the support protrusion P1 is provided on the top surface of the support part P that is located closest to the user, and is located toward the center when viewed from the front. This allows the storage part 1 to slide in the depth direction. When the storage part 1 slides, the support protrusions P1 are located between grooves provided on the bottom surfaces of the support parts P, and thus interfere with the storage part 1 in the left-right direction during sliding, preventing the storage part 1 from deviating in directions other than the depth direction and also restricting the sliding range. The support protrusions P1 may be provided on support parts P other than the support parts P described above, or may be provided on each support part P.

[0037] The first holding part constituent 21 also includes a leaf spring B. More specifically, the leaf spring B is provided along the depth direction on the rear side surface of each of the left insertion part 212L and the right insertion part 212R facing the storage part 1, and is arranged so as to bias the left insertion part 212L and the right insertion part 212R, respectively, with the rear side as a fixed axis and the front side as a free end, toward the adjacent left insertion part 212L and right insertion part 212R. In this way, even when the holder 2 is attached to the shelf board S, the leaf spring B can be gripped.

[0038] The second holding part constituent 22 is composed of a left second holding part constituent 22L and a right second holding part constituent 22R which are plane symmetrical to each other.

[0039] The left-side second holding part constituent 22L and the right-side second holding part constituent 22R are rod-shaped bodies that are long in the depth direction, and have a thickness that is large enough to allow them to be inserted into the insertion portion 212. This allows the left-side second holding part component 22L and the right-side second holding part component 22R to slide in the depth direction relative to the insertion portion 212 of the first holding part component 21 and to protrude. It should be noted that, although plastic is preferably used as the material for the left second holding part component 22L and the right second holding part component 22R, there are no particular limitations as long as it has rigidity.

[0040] The left-side second holding part component 22L and the right-side second holding part component 22R are each provided with a second mounting portion 221 that is attached to a shelf board S (see FIG. 7). More specifically, the second mounting portion 221 is an L-shaped hook in a side view, and its length in the height direction is the same as that of the first mounting portion 211. The second mounting portion 221 is provided opposite to the first mounting portion 211. The first mounting portion 211 and the second mounting portion 221 make it possible to mount the holding portion 2 in a state in which it is suspended from the shelf board S. In addition, the holding portion 2 can be mounted parallel to the bottom surface of the shelf board S.

[0041] In the embodiment, the surfaces of the first mounting portion 211 and the second mounting portion 221 that come into contact with the shelf board S are on the same plane parallel to the first holding part component 21, so that the first holding part component 21 is attached parallel to the bottom surface of the shelf board S. On the other hand, the protruding length of the second attachment portion 221 may be set longer than the protruding length of the first attachment portion 211, so that the second attachment portion 221 is inclined toward the front in the direction of gravity. In this case, it is preferable that the contacting surface is inclined at a predetermined angle.

[0042] As shown in FIG. 3 or 5, the fixing means F is provided with a first uneven portion F1 provided on the leaf spring B and a second uneven portion F2 provided on the second holding part constituent 22.

[0043] The first uneven portion F1 is provided on the surface of the leaf spring B adjacent to the second holding portion constituent 22. The second concave-convex portion F2 is provided along the depth direction on the surfaces of the left-side second holding part component 22L and the right-side second holding part component 22R that face the storage part 1.

[0044] A part of the second concave-convex portion F2 fits into the first concave-convex portion F1. This makes it possible to fix the length of the second holding part component 22 that protrudes in the depth direction from the first holding part component 21.

[0045] <How to use> Hereinafter, how to use the storage tool X will be described with reference to FIGS.

[0046] When mounting the storage device X on the shelf board S, the user first pulls each of the leaf springs B toward the interior space of the storage section 1, as shown in FIG. By doing so, the engagement between the first concave-convex portion F1 and the second concave-convex portion F2 is released, and the left second holding part component 22L and the right second holding part component 22R become slidable.

[0047] Next, the user slides the left-side second holding part component 22L and the right-side second holding part component 22R, respectively, to adjust the depth direction length of the holding part 2 according to the depth direction length of the shelf board S to be attached, and then biases each leaf spring B in the direction of the second uneven part F2. In this way, the protruding lengths of the left-side second retaining part component 22L and / or the right-side second retaining part component 22R from the first retaining part component 21 can be adjusted, and the first uneven portion F1 provided on the leaf spring B and the second uneven portion F2 provided on the second retaining part component 22 can be fitted together again, thereby making it possible to fix them.

[0048] Next, the user hooks the second attachment portion 221 to the rear side of the shelf board S, and hooks the first attachment portion 211 to the front side of the shelf board S. At this time, if necessary, the user may pull each of the leaf springs B toward the internal space of the storage unit 1 to readjust the length by which the left-side second holding part component 22L and the right-side second holding part component 22R protrude from the first holding part component 21. By doing this, it becomes possible to attach the storage device X to the shelf board S, as shown in FIG.

[0049] When storing an article L in the storage unit 1, first, the user grips the grip portion 12 as shown in FIG. 8, and pulls out the storage unit 1 toward the user. At this time, the user may grip either the grip body 121 or the protruding portion 122.

[0050] Next, the user stores the item L in the storage unit 1, and then the user grips the gripping portion 12 and slides the storage unit 1 toward the rear. In this way, the item L can be stored in the storage unit 1.

[0051] When removing the item L stored in the storage unit 1, the user pulls out the storage unit 1 in the same procedure as when storing the item L in the storage unit 1. In this way, the item L stored in the storage unit 1 can be removed.

[0052] <Effects> According to this embodiment, the holding unit 2 holds the storage unit 1 slidably in the depth direction of the shelf board S, and the sliding direction is inclined relative to the bottom surface of the shelf board S, making it easy to store and remove the article L in the storage unit 1. In addition, because the sliding direction is inclined relative to the bottom surface of the shelf board S, the storage unit 1 can slide easily.

[0053] In addition, the extension line of the sliding direction intersects with the surface including the bottom surface of the shelf board S at a point further back than the shelf board S, so that when the storage unit 1 is attached to the shelf board S, the front side is lower, making it easier to pull out the storage unit 1. In addition, even if the storage unit 1 is attached in a high place, it is easy to grip with the grip part 12.

[0054] In addition, the storage section 1 has a sliding protrusion 13, and the holding section 2, which is attached parallel to the bottom surface of the shelf board S, has a support section P on which the sliding protrusion 13 is placed, and the support section P has an inclined surface that slopes downward toward the front side. This creates a gap between the opening 11 of the storage section 1 and the holding section 2, making it easier to store and remove items in the storage section 1.

[0055] Moreover, the holding part 2 has a first holding part constituent 21 including the support part P, a second holding part constituent 22 configured so that the length of protrusion from the first holding part constituent 21 can be freely changed, and fixing means F that fixes the protrusion length from the first holding part constituent 21 at a predetermined position with respect to the second holding part constituent 22. Additionally, the first holding part constituent 21 includes a leaf spring B, and the fixing means F is provided with a first uneven portion F1 provided on the leaf spring B and a second uneven portion F2 provided on the second holding part constituent 22. Additionally, the leaf spring B is formed so that the first uneven portion F1 biases toward the second uneven portion F2, and the first uneven portion F1 fits into and is fixed to the second uneven portion F2. This configuration makes it possible to attach the storage device X according to the size of the shelf board S to which it is attached. Also, by being firmly fixed to the shelf board S, the holding part 2 is prevented from moving when the storage part 1 is slid. Also, it is possible to maintain the state in which the sliding direction is inclined.

[0056] Furthermore, the gripping portion 12 includes a protruding portion 122 that protrudes from the bottom surface of the storage portion 1, making it possible to grip the storage portion 1 from the ground surface.

[0057] The protruding portion 122 extends from the edge of the bottom surface of the storage portion 1, thereby making it possible to reduce manufacturing costs.

[0058] <Example of change> The shapes and dimensions of the components shown in the above-described embodiment are merely examples and can be modified in various ways based on design requirements, etc.

[0059] For example, the inclination of the top surface of each support portion P may be set so that it is closer to the front side than the bottom surface of the shelf board S. This makes it easier to slide the storage unit 1 toward the back, making it easier to return the storage unit 1 that has been pulled out. Furthermore, depending on the degree of inclination, when the user releases the grip portion 12, the storage portion 1 can automatically move in the depth direction.

[0060] Furthermore, for example, the length of the first mounting portion 211 in the height direction may be shorter than the length of the second mounting portion 221 in the height direction. In this way, the holding portion 2 is inclined in a direction away from the shelf board S toward the front side, so that the storage portion 1 can be easily pulled out without providing an inclination to the top surface of each support portion P.

[0061] Furthermore, for example, the contact surface of the sliding protrusion 13 with the support portion P may be inclined at approximately the same angle as the inclination of the top surface of the support portion P with respect to the storage portion 1. By doing so, the bottom surface of the storage section 1 becomes parallel to the ground surface in a side view, so that the article L can be stored in the storage section 1 in a stable state.

[0062] Furthermore, for example, the support portion P may be provided on each of the left and right sides, with the length in the depth direction being the same as that of the slide protrusion 13. By doing so, the area where the support part P comes into contact with the sliding protrusion 13 becomes larger, and the storage part 1 can be stably held.

[0063] Furthermore, for example, the first attachment portion 211 and the second attachment portion 221 may be extendable in the height direction, which makes it possible to adjust the size of the storage space formed by the storage unit 1 according to the length in the height direction of the article L to be stored. Here, the height direction is a direction perpendicular to both the depth direction and the left-right direction.

[0064] Furthermore, for example, the first attachment portion 211 and the second attachment portion 221 may each be provided with a wheel that is movable in the left-right direction and a locking mechanism that stops the rotation of the wheel. In this way, the storage item X attached to the shelf board S can be moved left and right to a desired position. In addition, the locking mechanism allows the storage item X to be fixed and attached.

[0065] Further, for example, the left-side second holding part component 22L and the right-side second holding part component 22R may be integral with each other. In this way, the rigidity of the holding part 2 is improved, and it becomes possible to firmly attach it to the shelf board S. [Explanation of symbols]
