It describes how the shelf body is set up and operated using movable shelves on which products can be placed and pushed out, allowing only the shelves to be replenished to be selected and pulled out to the front for refilling, thereby reducing the management burden on store managers.

[0005] Patent Document 3 discloses an assembly shelf for use in ordinary households, etc., that allows various items to be connected in a highly convenient manner. It describes how providing gaps in the shelf makes it easy to add outlets, connectors, etc., and how the aesthetic appearance can be maintained without adding any mounting structure. [Prior art documents] [Patent documents]

[0006] [Patent Document 1] JP 2023-33886 A [Patent Document 2] Patent Publication No. 2021-108801 [Patent Document 3] Utility model registration No. 3095668 Summary of the Invention [Problem to be solved by the invention]

[0007] In a work site such as a factory or a warehouse, it is common to temporarily store materials, semi-finished products, finished products, and other items on shelves after they have been brought in or manufactured, and then remove them from the shelves when a worker uses or transports them in the next process. In such a temporary storage shelf device, various items of different sizes, such as materials, semi-finished products, and finished products, are frequently taken in and out. In addition, the number of items varies depending on the peak and off-peak seasons.

[0008] A temporary storage shelf device is required to be easy to take in and out individually of items of different sizes (widths) while preventing them from falling off the shelf device. In addition, since items are frequently taken in and out of a temporary storage shelf device, it is important to reduce the physical burden on the worker, and it is required that items be easy to take out from the lower shelves. Furthermore, it is required that it is possible to confirm at a glance where items are placed.

[0009] The present disclosure is an invention made in consideration of the above problems, and has as its main object to provide a temporary storage shelf device that makes it easy to individually insert and remove items of different widths while preventing items from falling, makes it easy to remove items from the lower shelf, and allows the placement position of an item to be confirmed at a glance. [Means for solving the problem]

[0010] The present disclosure provides a temporary storage shelf device for temporarily placing items, the temporary storage shelf device having an upper shelf arranged at a predetermined position, and a lower shelf stored under the upper shelf and capable of being pulled out in a forward direction relative to the upper shelf, wherein the upper shelf has a first shelf with multiple tiers, a rail fixed to the front of the first shelf and extending in the left-right direction, and a stopper movably installed on the rail, and the lower shelf has a second shelf which is the lowest tier of the temporary storage shelf device, and an operation unit fixed to the front of the second shelf and which accepts operations for moving the lower shelf by a worker. Effect of the Invention

[0011] According to the present disclosure, it is possible to provide a temporary storage shelf device that prevents items from falling from the shelf device, makes it easy to individually insert and remove items of different widths, makes it easy to remove items from the lower shelf, and allows the placement position of the items to be confirmed at a glance. [Brief description of the drawings]

[Figure 4] 2A and 2B are schematic perspective and top views of an upper shelf in the present disclosure. [Diagram 5] Schematic cross-sectional view illustrating a blind rivet DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0013] Embodiments of the present disclosure will be described below with reference to the drawings and the like. However, the present disclosure can be implemented in many different modes and is not to be construed as limited to the description of the embodiments illustrated below. Also, for the purpose of making the description clearer, the drawings may schematically represent the width, thickness, shape, etc. of each part as compared with the actual form, but this is merely an example and does not limit the interpretation of the present disclosure. Further, in this specification and each drawing, elements that are the same as those described above with respect to the previously presented drawings may be denoted by the same reference numerals, and detailed descriptions thereof may be omitted as appropriate.

[0014] In this specification, when expressing the mode of arranging one member on another member, if simply denoted as "on" or "under", unless otherwise specified, it includes both the case where another member is arranged directly on or under so as to be in contact with a certain member, and the case where another member is arranged above or below a certain member with yet another member interposed therebetween. Also, in this specification, when expressing the mode of arranging one member on the surface of another member, if simply denoted as "on the surface side" or "on the surface", unless otherwise specified, it includes both the case where another member is arranged directly on or under so as to be in contact with a certain member, and the case where another member is arranged above or below a certain member with yet another member interposed therebetween.

[0015] Hereinafter, a temporary storage shelf device of the present disclosure will be described. FIG. 1 is a schematic perspective view showing an example of the temporary storage shelf device of the present disclosure. FIG. 2 is a schematic side view showing an example of the temporary storage shelf device of the present disclosure. FIG. 3 is a schematic front view showing an example of the temporary storage shelf device of the present disclosure.

[0016] 1 to 3 has an upper shelf 1 arranged at a predetermined position, and a lower shelf 2 stored in the upper shelf 1 and capable of being pulled out in a forward direction relative to the upper shelf 1. The upper shelf 1 has first shelves 11 (11a, 11b, 11c, 11d) of multiple levels, a rail 14 fixed to the front of the first shelf 11 and extending in the left-right direction, and a stopper 12 movably installed on the rail 14. The lower shelf 2 has a second shelf 21 which is the lowest level of the shelf device 100, and an operating unit 22 fixed to the front of the second shelf 21.

[0017] In this specification, the front-to-rear direction is defined as the direction toward the worker (nearby) when the temporary storage shelf device is viewed from the worker's side while the lower shelf is being pulled out. The left-to-right direction is defined as the direction when the temporary storage shelf device is viewed from the worker's side while being pulled out. In addition, the angle between the front-to-rear direction and the left-to-right direction in the horizontal direction is usually 90 degrees.

[0018] FIG. 4(a) is a schematic perspective view of the upper shelf 1 in the present disclosure. FIG. 4(b) and FIG. 4(c) are schematic top views of the upper shelf 1. As shown in FIG. 4, the stopper 12 in the present disclosure can move left and right along the rail 14. Therefore, the position of the stopper 12 can be adjusted according to the width of the article, so that articles of various widths can be placed while preventing them from falling. For example, in FIG. 4(b), the distance between the four stoppers 12 is set to be approximately the same, and four rows of articles W1 of the same width are placed. On the other hand, in FIG. 4(c), the distance between the stoppers 12 is adjusted according to the width of the articles W2 to W5 to be placed. The width of the article refers to the length of the width of the article in the left-right direction. It is preferable to adjust the position of each stopper 12 so that the center position of the stopper 12 in the left-right direction coincides with the center position of each of the articles W1 to W5.

[0019] Furthermore, in the present disclosure, the stopper can be moved left or right to easily remove the items individually.

[0020] In addition, because the lower shelf has an operating part, the worker can pull out the lower shelf by grabbing the operating part with his or her hand and pulling it towards himself or herself. Also, by pushing the lower shelf towards the upper shelf, the lower shelf can be stored under the upper shelf. This means that the lower shelf can be taken in and out with less physical strain, and pulling out the lower shelf also makes it easy to take out items from the back of the second shelf.

[0021] Furthermore, when an operator looks at the shelf device from the front, all that exists between the operator and the items on the shelf device is the stopper on the upper shelf or the operating part on the lower shelf, so the items are easily visible and it is possible to see at a glance what is placed where.

[0022] Here, the shelves described in Patent Document 1 and Patent Document 2 are intended for displaying products in mass retailers such as supermarkets and convenience stores, and are intended for use on the assumption that the width of the products to be displayed is constant, probably because the size (width) of the products to be displayed does not vary much. Therefore, they do not fully meet the needs of workplaces such as factories that handle items of different widths and deal with frequent increases and decreases in the number of items. For example, the shelves described in Patent Document 2 use movable shelves to enable items to be removed one by one, but because the width of the shelves cannot be freely changed, they are not suitable for use in workplaces such as factories and warehouses.

[0023] The shelves described in Patent Document 1 have the problem that when items are taken out one by one, they may come into contact with other items displayed nearby, causing them to fall. Also, when pulling out the bottom shelf, the worker must bend over, which places a great strain on the worker's body. The shelves described in Patent Document 3 have the problem that it is difficult to take out items from the bottom shelves, and there is a possibility that other items may fall when items are frequently taken in and out.

[0024] Furthermore, in furniture used in ordinary households, it is often required that items placed on shelves are not conspicuous so as not to spoil the aesthetic appearance, but in work sites such as factories and warehouses, items are frequently taken in and out, so it is desirable to be able to see at a glance what is placed where.

[0025] According to the present invention, a temporary shelf device is provided that makes it easy to individually load and unload items of different widths while preventing items from falling off the shelf device, makes it easy to remove items from the lower shelf, and allows the placement position of an item to be confirmed at a glance. Therefore, the temporary shelf device is particularly useful in work sites such as factories and warehouses where the number of items frequently increases and decreases due to peak and off-season periods.

[0026] The configurations and characteristics of the shelf device according to the present disclosure will be described in detail below.

[0027] 1. Upper shelf The upper shelf in the present disclosure has a plurality of first shelves. The number of shelves of the upper shelf is not particularly limited as long as it is two or more, and may be three or more, four or more, or six or more. The upper shelf 11 in Figs. 1 to 3 has four first shelves 11a to 11d. As shown in Fig. 1, the first shelf 1 has, for example, a plurality of first columnar members extending in the front-rear direction. On the other hand, the first shelf may be a single plate-like member.

[0028] The height of the top first shelf is preferably 180 cm or less, and more preferably 170 cm or less. If it is less than the above height, the worker can reach it by stretching out his / her hand, which improves workability. On the other hand, for example, it is 140 cm or more. As shown in FIG. 2, the height H1 of the top first shelf refers to the shortest distance between the floor surface G and the placement surface of the top first shelf 11a.

[0029] Each of the first shelves of the multiple tiers may have rollers arranged on the placement surface. This provides good sliding properties, making it easy to remove items from the back of the shelf. The placement surface may also be inclined so that the height decreases from the back of the shelf to the front. In the upper shelf of the present disclosure, a stopper is arranged in front of the first shelf, so that even if the placement surface of the first shelf is inclined, it is possible to prevent items from falling. The inclination angle may be different or the same for each first shelf.

[0030] As shown in FIG. 1, the upper shelf 1 has, for example, a pair of left and right supports 13 (13X, 13Y) that support the first shelves 1 of multiple levels. The supports 13X, 13Y may each include a plurality of second columnar members 13a, 13b extending in the vertical direction. The number of second columnar members included in the support is not particularly limited, but may be, for example, two or more, three or more, four or more, or ten or more. Meanwhile, the support may be a single plate-like member.

[0031] 1, the upper shelf 1 has a rail 14 that is fixed to the front of the first shelf 11 and extends in the left-right direction. The upper shelf 1 also has a stopper 12 that is movably installed on the rail 14. The rail 14 is, for example, a member that connects the second columnar members 13a to each other.

[0032] As shown in FIG. 1, the rails 14 are preferably fixed to each of the first shelves 11 in the multiple tiers. The stoppers 12 are preferably movably installed on each of the first shelves 11 in the multiple tiers. The number of stoppers 12 on each first shelf 11 may be different or the same. The number of stoppers 12 on each first shelf 11 is not particularly limited, but is, for example, 2 or more, may be 3 or more, or may be 4 or more. On the other hand, it is, for example, 10 or less.

[0033] The shape of the stopper is not particularly limited. As shown in Figures 1 to 3, the shape of the stopper 12 when viewed from the front may be a U-shape with an opening downward, a U-shape, or a rectangular shape.

[0034] As shown in FIG. 2, it is preferable that the upper shelf 1 has slide rails 15 that support the lower shelf 2 so as to be movable in the front-rear direction. By having the slide rails 15, it becomes possible to move the lower shelf 2 back and forth with respect to the upper shelf 1 without shifting in the left-right direction.

[0035] As shown in FIG. 1, in order to suppress the fall of articles from the left and right, the upper shelf 1 may have side portions 16 disposed at both left and right ends of the first shelf 11. It is preferable that the side portions 16 are disposed on each of the plurality of stages of the first shelf 11.

[0036] 2. Lower shelf As shown in FIGS. 1 to 3, the lower shelf in the present disclosure has a second shelf 21 that is the lowermost stage of the shelf device 100 and an operation unit 22 fixed in front of the second shelf 21.

[0037] The second shelf is the lowermost shelf. As shown in FIG. 1, it is preferable that the second shelf 21 has a plurality of third columnar members extending in the front-rear direction. On the other hand, the second shelf may be a single plate-like member.

[0038] The height of the second shelf is preferably, for example, 40 cm or more, and more preferably 50 cm or more. This is because the burden on the operator's body when placing and lifting articles is reduced. On the other hand, for example, it is 100 cm or less. As shown in FIGS. 2 and 3, the height H2 of the second shelf refers to the shortest distance between the floor surface G and the placement surface of the second shelf 21.

[0039] The lower shelf in the present disclosure has an operating unit fixed to the front of the second shelf. The number of operating units in the second shelf is not particularly limited, and may be one or more than two. The shape of the operating unit 22 is not particularly limited, but for example, as shown in FIG. 1, it is preferable to have a columnar member 22a extending vertically and a handle 22b extending in the left-right direction provided on the upper part of the columnar member. The operator can easily pull the lower shelf forward by grabbing the handle with his / her hand and pulling it toward himself / herself. On the other hand, the lower part of the stand can be easily moved into the upper part of the stand by grabbing the handle with his / her hand and pushing it into the upper shelf. The height of the handle 22b is not particularly limited, but is, for example, 70 cm or more and 120 cm or less, and preferably 70 cm or more and 80 cm or less, from the viewpoint of workability. As shown in FIG. 2 and FIG. 3, the height H22 of the handle 22b refers to the longest distance between the floor surface G and the upper end of the handle 22b.

[0040] The operating portion also functions as a stopper to prevent articles from flying out forward when the lower shelf is pulled out.

[0041] The lower shelf in the present disclosure may have a partition plate that is erected perpendicular to the placement surface of the second shelf to divide the second shelf into multiple regions. The partition plate may extend in the front-rear direction to divide the width (left-right direction) of the second shelf. On the other hand, the partition plate may extend in the left-right direction to divide the depth (front-rear direction) of the second shelf. In addition, the lower shelf may have side portions disposed on both the left and right ends of the second shelf to prevent items from falling from the left and right.

[0042] 1, the lower shelf 2 is preferably movable by having casters 23. The lower shelf 2 may also have a rear stopper 25 disposed behind the second shelf 21. By having the rear stopper 25, it is possible to prevent items from falling backward when the lower shelf is stored in the upper shelf.

[0043] The lower shelf in the present disclosure may have rollers 24 that run on slide rails 15 that extend in the front-rear direction, as shown in Fig. 2. This is because the lower shelf can be slid along the front-rear direction without being displaced in the left-right direction.

[0044] 3.Other (1) Slide mechanism In the temporary storage shelf device of the present disclosure, the lower shelf can be pulled out in a forward direction relative to the upper shelf. The slide mechanism that enables the lower shelf to be pulled out is not particularly limited, but for example, as shown in Fig. 2, it has a slide rail 15 extending in the front-rear direction below the upper shelf 1, and a roller 24 that slides on the slide rail 15 and is provided below the second shelf 21 of the lower shelf 2. The slide mechanism is preferably disposed, for example, near the left and right ends of the lower shelf.

[0045] The sliding mechanism is not limited to the above configuration, but may be any mechanism that has a rail extending in the front-to-rear direction on either the lower shelf or the upper shelf, and has a sliding part that slides against the rail, such as a roller that rolls on the rail or a protrusion or block that slides on the rail, on the other of the lower shelf or upper shelf, allowing the lower shelf to slide freely in the front-to-rear direction relative to the upper shelf.

[0046] (2) Fixtures In the temporary storage shelf device of the present disclosure, the members are preferably fixed to each other by a blind rivet. FIG. 5 is a schematic cross-sectional view for explaining how a blind rivet is used to fix a member A and a member B. The blind rivet 50 has a flange 50a, a sleeve 50b extending in the axial direction from the flange 50a, and a mandrel 50c inserted into the sleeve 50b. A barb is provided at the end T of the mandrel 50c (i.e., the end opposite the flange 50a) and engages with a part of the sleeve 50b. After the blind rivet 50 is inserted into the fastening holes of the members A and B, when the mandrel 50c is pulled toward the axial front side, the barb of the mandrel 50c plastically deforms the end of the sleeve 50b so as to bulge in the radial direction. The dashed line in FIG. 5 indicates the shape of the sleeve 50b after plastic deformation.

[0047] By using blind rivets, it is possible to reduce the weight of the temporary storage shelf device while maintaining strength, compared to when a commercially available connector is used. For example, when creating a temporary storage shelf device with seven shelves, the number of connectors required is equivalent to 642. If a commercially available connector (multi-connector made by SUS Corporation) is used, the weight of the fastening part is equivalent to approximately 12.2 kg. In contrast, by using blind rivets (blind rivets (round head) / NST, Lobtex Corporation) as the fastener, the weight of the fastening part can be reduced to approximately 1.1 kg. In other words, a weight reduction of 91% can be achieved.

[0048] Furthermore, in terms of strength, a commercially available connector (a multi-connector made by SUS Corporation) has a sliding load of 800N and a tensile load of 300N, whereas a blind rivet (blind rivet (round head) / NST made by Lobtex Corporation) has a sliding load of 1560N and a tensile load of 1240N. In other words, the sliding load is 2.0 times and the tensile load is 4.1 times.

[0049] In this way, the use of blind rivets makes it possible to achieve high strength and lightweight construction. Furthermore, by using blind rivets, two or more parts can be fixed (fastened) together from only one side. This improves the workability of manufacturing, installing, and transporting the shelves.

[0050] (3) Upper and lower shelves The shelf device according to the present disclosure may have one lower shelf for one upper shelf as shown in Fig. 1 to Fig. 3, but is not limited to this embodiment. For example, two or more lower shelves may be provided for one upper shelf. In this case, each lower shelf can be independently drawn out from the upper shelf.

[0051] The members constituting the temporary storage shelf device of the present disclosure are preferably made of metal, since this provides high strength. Among these, it is more preferable that the members be made of aluminum, since this provides high strength and light weight.

[0052] 4.Goods The articles to be placed on the temporary storage shelf device of the present disclosure include materials, finished products, semi-finished products, etc. The shape of the articles is preferably a box shape.

[0053] 5.Applications The temporary storage shelf device in the present disclosure is a shelf device for temporarily placing items such as materials, semi-finished products, and finished products after delivery or manufacture until they are used or transported by workers in the next process. The temporary storage shelf device is used in work sites such as factories and warehouses. The temporary storage shelf device in the present disclosure is a temporary storage shelf device that allows items of different widths to be individually put in and taken out, makes it easy to take items out of the lower shelves, and allows you to check at a glance what is placed where. Therefore, it is more effective when used in work sites such as factories and warehouses where the number of items frequently increases and decreases due to busy and slow seasons.

[0054] The temporary storage shelf device of the present disclosure may be used with its rear side facing the wall of a factory, warehouse, etc., or may be disposed so that the rear side has a space for people to enter. In the latter case, it becomes possible to place an article on the rear side of the shelf device.
