Description

[Technical field]

[0001] The present invention relates to a shelf that is attached to a wall surface. [Background technology]

[0002] For example, shelves are installed on the walls of kitchens, etc. to store or display various items. Patent Document 1 describes a hanging shelf (rack) that is attached to a horizontal bar installed on the wall of a kitchen.

[0003] This hanging shelf has a hanging piece, an inclined piece, a vertical piece, and a horizontal piece. The hanging piece is a section that can be hung on a horizontal bar that is installed in a protruding manner on the kitchen wall. The inclined piece is a section that is bent from the hanging piece toward the wall. The vertical piece is a section that is in near contact with the wall. The horizontal piece is a section on which cooking utensils and the like can be placed.

[0004] In this hanging shelf, when the hanging piece is hung on the bar that is installed on the wall to protrude, the inclined piece is bent from the hanging piece toward the wall, so the vertical piece almost abuts against the wall. For this reason, Patent Document 1 says that it is possible to effectively use the space below the horizontal bar and eliminate dead space. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] Japanese Utility Model Application Publication No. 4-125846 Summary of the Invention [Problem to be solved by the invention]

[0006] Patent Document 1 gives two examples of hanging shelves (racks) that are attached to a horizontal bar: a plate stand and a knife holder. Similar storage devices are also available on the market, such as hooks for hanging ladles and other cooking utensils, such as frying pans. However, although these hanging shelves can be selected according to the desired function, each part only has one function. Since the width of the kitchen wall on which the horizontal bar can be installed is limited, the number of hanging shelves (i.e., the number of selectable functions) is inevitably limited to two or three. Therefore, there is a problem that the storage capacity is not increased much and the wall space is used in a low efficiency manner.

[0007] Furthermore, in the conventional technology, the shapes and structures of the hanging shelves (racks) are completely different for each function, such as shelves for placing items, hooks for hanging items, knife holders, etc. For this reason, there was a problem that when they were installed side by side on a horizontal bar, there was no sense of unity in the design.

[0008] In view of the above problems, the present invention has an object to provide a shelf that has multiple functions with a simple configuration and that can achieve a sense of design unity when multiple shelves are lined up together. [Means for solving the problem]

[0009] In order to solve the above problems, a typical configuration of a shelf according to the present invention is a shelf that is attached to a wall surface, and comprises a shelf board having a vertical board that is attached to the wall surface and a horizontal board that stands upright on the vertical board, and a bar unit that is removably attached to the horizontal board, and the bar unit is attached to the horizontal board at any position in the depth direction of the horizontal board so that the bar is located above or below the horizontal board.

[0010] In the above configuration, the bar can be placed above or below the horizontal plate with the bar unit detachably attached at any position in the depth direction of the horizontal plate of the shelf. Therefore, as an example, if the bar unit is attached to the front side of the horizontal plate, i.e., the side away from the wall, and the bar is placed above the horizontal plate, the bar can prevent various items from falling when placed on the horizontal plate. Also, if the bar unit is attached to the back side of the horizontal plate, i.e., the side closer to the wall, with the bar placed above the horizontal plate, various items such as tablets and books can be supported by the bar.

[0011] Furthermore, by arranging the bar below the horizontal plate, various items such as towels, kitchen paper, ladles, etc. can be hung on the bar. Furthermore, by removably attaching multiple bar units to the horizontal plate of the shelf board and arranging bars above and below the horizontal plate, respectively, or arranging multiple bars only above or only below the horizontal plate, further functions can be added.

[0012] Therefore, with the above-mentioned configuration, the bar unit can be detachably attached to the horizontal plate of the shelf board, and the horizontal plate can have multiple functions in addition to placing various items on it, thereby saving space. Even if multiple shelves are installed side by side, the main components, the vertical and horizontal plates, are the same, so a sense of unity in design can be achieved and the aesthetic appearance can be improved.

[0013] The above-mentioned bar unit has a bar and two columnar members, the base of which can be fixed to the horizontal plate of the shelf, and the tip side of the columnar member is formed with a conical hole base whose diameter decreases toward the side facing the other columnar member, and both ends of the bar are provided with truncated cone end members whose diameter decreases toward the center of the bar, and the bar unit is formed by fitting the end members of the bar into the bases of the columnar members.

[0014] In this way, when attaching the bar to the two columnar members, the truncated cone end members at both ends of the bar are fitted into the bases of the conical holes formed at the tip side of the columnar members. This applies a force toward the center of the bar, pulling the bar into a fixed position in the width direction. This allows the end members of the bar and the bases of the columnar members to fit together without misalignment. This allows the bar to be securely attached to the two columnar members.

[0015] It is preferable that a plurality of bases for mounting the bars be provided at different heights on the tip side of the columnar member.

[0016] This allows the height of the bar to be changed by attaching the bar to a base at a different height, improving convenience. For example, if the bar unit is attached to a horizontal plate so that the bar is located below the horizontal plate of the shelf, by attaching the bar to a base at a high position, dish towels and the like can be hung on the bar at a position away from the kitchen worktop, and by attaching the bar to a base at a low position, for example, large-diameter kitchen paper made overseas can be attached to the bar.

[0017] A hook is attached to the wall surface, and a hook receiver is attached to the back of the vertical plate of the shelf, the hook receiver having a frame-shaped frame portion that is symmetrical in the vertical direction, the frame portion being provided at the center of the upper and lower edges and raised to form a gap between it and the vertical plate, and having an engagement portion that engages with the hook, and inclined surfaces formed on both sides of the engagement portion inside the frame portion and inclined so as to approach the engagement portion as it goes in the vertical direction.

[0018] In this way, the vertical shelf board has a frame-shaped hook receiver attached to the back surface, which is symmetrical from top to bottom. Therefore, even if the vertical shelf is turned upside down, the hook receiver can be attached by engaging the upper and lower edge hooks with the hooks on the wall. This allows the height of the horizontal board, which is erected on the vertical board and on which various items are placed, to be changed, improving convenience.

[0019] Also, when attaching the shelf board to the hook on the wall, since the hook receiver is attached to the back of the vertical board, it may be difficult to see and position the hook receiver. Therefore, in the above configuration, inclined surfaces are formed on both sides of the engagement part of the hook receiver. As a result, when attaching the shelf board to the hook on the wall, simply positioning the hook on the wall inside the frame part of the hook receiver allows the hook on the wall to be guided to the engagement part while contacting the inclined surface of the frame part and easily engage with the engagement part. Therefore, even if the hook receiver of the shelf board is difficult to see, the shelf board can be easily attached to the hook on the wall.

[0020] The above-mentioned hook is formed with tongues on the top and bottom thereof which engage with the top and bottom engaging portions of the hook receiver, and the length of the upper tongue is set longer than that of the lower tongue, so that when the upper tongue is inserted into the upper engaging portion, the lower tongue does not reach the lower engaging portion, and when the lower tongue engages with the lower engaging portion, the upper tongue maintains its engagement with the upper engaging portion.

[0021] In this way, the lower tongue is shorter than the upper tongue so that it does not reach the lower engagement part even when the upper tongue is inserted into the upper engagement part. This allows the upper tongue of the hook to be securely engaged with the upper engagement part of the hook receiver, and the shelf to be securely attached to the hook on the wall.

[0022] In addition, the upper tongue is set longer than the lower tongue so that it can maintain engagement with the upper engagement part even when the lower tongue engages with the lower engagement part. This keeps the upper tongue of the hook engaged with the upper engagement part of the hook receiver even when the shelf is pushed up from below by an impact from below, preventing the shelf from falling off the wall. Effect of the Invention

[0023] According to the present invention, it is possible to provide a shelf that has a plurality of functions with a simple configuration and that can provide a sense of unity in design when multiple shelves are arranged side by side. [Brief description of the drawings]

[Figure 8] 7(a) to 7(c) are diagrams showing a procedure for attaching the shelf of FIG. 7(a) to a wall surface. [Figure 9] FIG. 8(c) is a diagram showing a state in which the shelf in FIG. 8(c) receives an impact from below. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0025] A preferred embodiment of the present invention will be described in detail below with reference to the accompanying drawings. The dimensions, materials, and other specific values ​​shown in the embodiment are merely examples for facilitating understanding of the invention, and do not limit the present invention unless otherwise specified. In this specification and drawings, elements having substantially the same functions and configurations are given the same reference numerals to avoid repeated explanations, and elements not directly related to the present invention are not shown.

[0026] Fig. 1 is a diagram showing a shelf 100 according to an embodiment of the present invention. The shelf 100 is attached to a wall surface 102 in a kitchen, for example, and is used to store or display various items. As shown in Fig. 1(a), the shelf 100 comprises a shelf board 104 and a bar unit 106. The shelf board 104 has a vertical board 108 attached to the wall surface 102, and a horizontal board 110. The horizontal board 110 stands upright from the vertical board 108, and forms a horizontal surface on which various items can be placed.

[0027] The bar unit 106 is a unit that is detachably attached to the horizontal plate 110 of the shelf board 104, and has a bar 112 and a pair of two columnar members 114, 116 on the left and right sides, which are assembled together. Note that Fig. 1(a) also shows the state of the bar unit 106 before each member is assembled.

[0028] Fixing parts 118, 120 are formed at the bases of the columnar members 114, 116. The fixing parts 118, 120 vertically sandwich side edges 122, 124 along the depth direction of the horizontal plate 110 of the shelf board 104, and detachably attach the columnar members 114, 116 to any positions in the depth direction of the horizontal plate 110. Hereinafter, the side of the horizontal plate 110 away from the wall surface 102 is referred to as the front side, and the side approaching the wall surface 102 is referred to as the back side.

[0029] Furthermore, a plurality of (here, two) pedestals 126, 128 are provided at different heights on the tip side of columnar member 114. Furthermore, pedestals 130, 132 are provided at different heights on the tip side of columnar member 116. Note that columnar members 114, 116 have bilaterally symmetrical structures and have similar functions, so the following description of columnar member 116 will be omitted where appropriate.

[0030] End members 134, 136 are provided on both ends of the bar 112. The end members 134, 136 of the bar 112 are fitted into, for example, the bases 126, 130 of the columnar members 114, 116 (see FIG. 4), thereby forming the bar unit 106.

[0031] The bar unit 106 is detachably attached to the horizontal plate 110 at any position in the depth direction of the horizontal plate 110 by the columnar members 114, 116 so that the bar 112 is located above or below the horizontal plate 110 of the shelf board 104 (see FIG. 2). In other words, the bar unit 106 can be attached upside down to the horizontal plate 110, or moved to the back or front side of the horizontal plate 110 and attached.

[0032] Also, hooks 138, 140 shown in Fig. 1(a) are attached to the wall surface 102. Also, frame-shaped hook receivers 144, 146 that are vertically symmetrical are attached to the back surface 142 of the vertical plate 108 of the shelf board 104 shown in Fig. 1(b). Therefore, even if the vertical plate 108 is turned upside down, the shelf board 104 can be attached by engaging the hook receivers 144, 146 with the hooks 138, 140 of the wall surface 102. Note that in Fig. 1(b), the back surfaces of the hooks 118, 120 are shown through the wall surface 102.

[0033] 1, the shelf board 104 is in a position where the horizontal board 110 is located below the vertical board 108. Furthermore, the bar unit 106 is detachably attached to the horizontal board 110 such that the bar 112 is located above the horizontal board 110.

[0034] Here, the bar unit 106 can be attached to the horizontal plate 110 at any position in the depth direction of the horizontal plate 110. And the shelf plate 104 can be attached to the wall surface 102 even if the vertical plate 108 is turned upside down. Therefore, the shelf 100 can be attached to the wall surface 102 in a variety of different styles (see FIG. 2).

[0035] 2 is a diagram showing shelves 101A to 101H of various different styles. In shelf 101A, columnar members 114, 116 of bar unit 106 are attached to the front side of horizontal plate 110 of shelf board 104, and further, bar 122 is disposed above horizontal plate 110. Shelf board 104 is oriented such that horizontal plate 110 is located below vertical plate 108. In this type of shelf 101A, when various items (such as bottles containing seasonings) are placed on horizontal plate 110, bar 112 can prevent the various items from falling.

[0036] In shelf 101B, compared to shelf 101A, bar unit 106 is attached to the back side of horizontal plate 110, so that when various items (such as books or tablets) are placed on horizontal plate 110, the various items can be supported by bar 112.

[0037] In shelf 101C, columnar members 114, 116 of bar unit 106A are attached to the front side of horizontal plate 110 of shelf board 104, and further, bar 122 is disposed below horizontal plate 110. In such shelf 101C, various items (e.g., ornamental plants) can be placed on horizontal plate 110 while various items (e.g., kitchen paper) can be hung on bar 112.

[0038] Compared to shelf 101A, shelf 101D adds bar unit 106A that places bar 122 below horizontal plate 110. As a result, when various items (such as potted plants) are placed on horizontal plate 110, shelf 101D not only supports the items with bar 112 of bar unit 106, but also allows various items (such as kitchen paper) to be hung on bar 112 of bar unit 106A.

[0039] In shelf 101E, vertical plate 108 of shelf 104 is upside down compared to shelf 101A, so that the height of horizontal plate 110 on which various items (such as bottles containing seasonings) are placed can be changed. In shelf 101E, pillar members 114, 116 of bar unit 106 are attached to the front side of horizontal plate 110 of shelf 104, and further, bar 122 is disposed above horizontal plate 110, so that bar 112 can prevent various items from falling.

[0040] Unlike shelf 101E, shelf 101F has a bar unit 106A attached to horizontal plate 110, which disposes bar 122 below horizontal plate 110, instead of bar unit 106. With shelf 101F like this, various items (such as containers) can be placed on horizontal plate 110 while various items (such as kitchen paper) are hung on bar 112.

[0041] Compared to shelf 101E, shelf 101G adds bar unit 106A that arranges bar 122 below horizontal plate 110. As a result, when various items are placed on horizontal plate 110, shelf 101G not only supports the items with bar 112 of bar unit 106, but also allows various items (e.g., kitchen paper) to be hung on bar 112 of bar unit 106A.

[0042] Compared to shelf 101F, shelf 101H adds a bar unit 106A that arranges bar 122 below horizontal plate 110. As a result, shelf 101H has two bars 112 arranged side by side below horizontal plate 110. Therefore, shelf 101H can increase the height of horizontal plate 110 even if wall surface 102 (see FIG. 1) such as a fixture facing wall is low. Various items (such as dish towels and ladles) can be hung on these two bars 112.

[0043] 1 has a simple configuration in which bar unit 106 is detachably attached to horizontal plate 110 of shelf board 104, and shelves 101A-101H of different styles as shown in Fig. 2 can be appropriately assembled. Shelf 100 not only allows various items to be placed on horizontal plate 110, but also has multiple functions such as preventing various parts from falling with bar 112, supporting various parts, and even hanging various items on bar 112, thereby enabling space saving.

[0044] Furthermore, even if multiple shelves 100 are installed side by side, the main components, the vertical boards 108 and horizontal boards 110, are common, so a sense of unity in design can be achieved and the aesthetic appearance can be improved.

[0045] Fig. 3 is an enlarged view of a portion of bar units 106A and 106B. Bar unit 106A shown in Fig. 3(a) is used in shelves 101C, 101D, 101F, 101G, and 101H in Fig. 2, and has columnar members 114 and 116 attached to horizontal plate 110 of shelf board 104, and bar 122 disposed below horizontal plate 110.

[0046] 1 shown in Fig. 1 is clamped from above and below, and then the urea screws 147 are tightened to secure the fixing parts 118 formed at the bases of the columnar members 114 to the side edges 122 of the horizontal plate 110. Note that the fixing parts 118 are not limited to the urea screws 147, and any suitable mechanism capable of clamping the side edges 122 of the horizontal plate 110 of the shelf board 104 from above and below can be used.

[0047] As described above, the bases 126, 128 are provided at different heights on the tip side of the columnar member 114. In the bar unit 106A, the end member 134 of the bar 112 is fitted into the base 126 of the columnar member 114 as shown in FIG. 3(a). In the bar unit 106B shown in FIG. 3(b), the end member 134 of the bar 112 is fitted into the base 128 of the columnar member 114. In this way, in the bar units 106A, 106B, the height of the bar 112 can be changed by attaching the bar 112 to the bases 126, 128 provided at different heights, thereby improving convenience.

[0048] Fig. 4 is a diagram showing a state in which the bar unit 106A of Fig. 3(a) is assembled. Fig. 5 is a diagram showing a shelf 101F equipped with the bar unit 106A of Fig. 4.

[0049] 5 is configured such that columnar members 114, 116 of bar unit 106A are attached to the front side of horizontal plate 110 of shelf board 104, and further, bar 122 is disposed below horizontal plate 110 (see FIG. 2). Additionally, shelf board 104 is oriented such that horizontal plate 110 is located above vertical plate 108.

[0050] The base 126 of the columnar member 114 forms a conical hole as shown in Figure 4(a) and has a diameter that decreases toward the side facing the other columnar member 116 as shown in Figures 4(b) and 4(c). The base 130 of the columnar member 116 also forms a conical hole and has a diameter that decreases toward the side facing the columnar member 114. The end members 134, 136 at both ends of the bar 122 form truncated cones and have a diameter that decreases toward the center of the bar 112.

[0051] When the end members 134, 136 of such a bar 122 are fitted into the bases 126, 130 of the columnar members 114, 116, one end member 134 may be hooked onto the base 126 and then the other end member 136 may be attached to the base 130 (see Figure 5(a)), or both end members 134, 136 may be attached to the bases 126, 130 simultaneously (see Figure 5(b)).

[0052] Here, the end members 134, 136 of the bar 122 form a truncated cone, and the seats 126, 130 of the columnar members 114, 116 form a conical hole. For this reason, when the end members 134, 136 are fitted into the seats 126, 130 as shown in Figure 4(b), even if the positions are slightly misaligned, a force acts toward the center of the bar 122, so that the bar 122 is pulled into a fixed position in the frontage direction.

[0053] Therefore, the end members 134, 136 of the bar 122 and the seats 126, 130 of the columnar members 114, 116 fit together without misalignment, as shown in Figure 4(c). Therefore, the bar 122 can be securely attached to the two columnar members 114, 116 to form the bar unit 106A.

[0054] Here, the user can appropriately assemble and use shelves 101A-101H of various different styles, for example as shown in Fig. 2. Therefore, the mounting position of bar 122 may frequently change to above or below horizontal plate 110 of shelf board 104, or even to the front or back side of horizontal plate 110, depending on the user's usage method. In such a case, even if the positions are slightly shifted when fitting end members 134, 136 of bar 122 into bases 126, 130 as described above, bar 122 can be reliably mounted to two columnar members 114, 116, so shelves 101A-101H can be assembled in a short time, improving workability.

[0055] Fig. 6 is a diagram showing a shelf 101I with a different style from the shelf 101F in Fig. 5. As shown in Fig. 6(a), in the shelf 101I, the bar unit 106A is disposed on the rear side of the horizontal plate 110 of the shelf board 104 compared to the shelf 101F. Also, in the shelf 101I, as an example, the vertical plate 108 of the shelf board 104 is attached to the wall surface 102 above the worktop A.

[0056] When user B looks down on shelf 101I from diagonally above as shown in Fig. 6(a) (see dotted line C), shelf 101I as seen by user B is in a state in which bar 112 (see Fig. 6(a)) of bar unit 106A is hidden by horizontal plate 110 of shelf 104 as shown in Fig. 6(b). However, as described above, even if the positions are slightly misaligned when fitting end members 134, 136 of bar 122 into bases 126, 130, bar 122 is pulled into a fixed position in the frontage direction.

[0057] Therefore, when the bar 122 cannot be seen due to the positional relationship between the shelf 101I and user B, user B can reliably attach the bar 122 to the two columnar members 114, 116 by hooking one end member 134 of the bar 122 onto the base 126 as shown in Fig. 5(a) and then attaching the other end member 136 to the base 130. In other words, user B does not need to attach both end members 134, 136 of the bar 122 to the bases 126, 130 simultaneously (see Fig. 5(b)) in a state where the bar 122 cannot be seen, and the attachment work does not require much effort.

[0058] Fig. 7 is a diagram illustrating hook receivers 144, 146 of shelf 100 in Fig. 1 and hooks 138, 140 of wall surface 102. As shown in Fig. 7(a), hook receivers 144, 146 are attached to back surface 142 of vertical plate 108 of shelf board 104, and hooks 138, 140 are attached to wall surface 102. Note that hook receivers 144, 146 and hooks 138, 140 each have the same structure and similar functions, so the following description of hook receiver 146 and hook 140 will be omitted as appropriate.

[0059] The hook receiver 144 has a frame portion 148 as shown in FIG. 7(b). The frame portion 148 forms a frame shape that is symmetrical in the up-down direction, and has engagement portions 150, 152 and inclined surfaces 154, 156, 158, 160. The engagement portion 150 is provided at the center of an upper side 162 of the frame portion 148, and is raised so as to form a gap 164 shown in FIG. 7(a) between the frame portion 148 and the vertical plate 108. The engagement portion 152 is provided at the center of a lower side 166 (see FIG. 7(b)) of the frame portion 148, and is raised so as to form a gap 168 shown in FIG. 7(a) between the frame portion 148 and the vertical plate 108.

[0060] 7(b), the inclined surfaces 154, 156 are formed on both sides of the engaging portion 150 inside the frame portion 148, and are inclined so as to approach the engaging portion 150 as they extend upward. The inclined surfaces 158, 160 are formed on both sides of the engaging portion 152 inside the frame portion 148, and are inclined so as to approach the engaging portion 152 as they extend downward.

[0061] 7(c), an upper tongue piece 170 and a lower tongue piece 172 are formed above and below the hook 138. The upper tongue piece 170 is set to be longer than the lower tongue piece 172.

[0062] Here, the vertical length of the inside of frame 148 of hook receiver 144 shown in Fig. 7(b) is dimension W1, the vertical length of hook 138 shown in Fig. 7(c) excluding lower tongue piece 172 is dimension W2, and the vertical length of hook 138 excluding upper tongue piece 170 is dimension W3. In hook receiver 144 and hook 138, these dimensions are set so that "W2>W1>W3".

[0063] Figure 8 is a diagram showing the procedure for attaching the shelf 100 of Figure 7(a) to the wall surface 102. First, the hook receivers 144, 146 attached to the back surface 142 of the vertical plate 108 of the shelf board 104 of Figure 7 are hooked onto the hooks 138, 140 of the wall surface 102. At this time, for example, as shown by the arrow in Figure 8(a), the engagement portion 150 of the hook receiver 144 is brought close to the tongue piece 170 on the hook 138.

[0064] However, because the hook receiver 144 is attached to the back surface 142 of the vertical plate 108, it may be difficult to see and position the hook receiver 144. In consideration of such a situation, inclined surfaces 154, 156 are formed on both sides of the engagement portion 150 on the inside of the frame portion 148 of the hook receiver 144.

[0065] That is, by simply positioning hook 138 of wall surface 102 inside frame portion 148 as shown in FIG. 8(d), tongue piece 170 on top of hook 138 is guided to engagement portion 150 as indicated by the arrow in the figure while contacting either inclined surface 154, 156 (in this case inclined surface 154) of frame portion 148.

[0066] As a result, as shown in Fig. 8(b), the tongue 170 on the hook 138 easily engages with the engaging portion 150 of the hook receiver 144. Then, when the tongue 170 on the hook 138 is inserted into and engaged with the engaging portion 150 of the hook receiver 144, the lower side of the shelf board 104, i.e., the horizontal board 110, is brought closer to the wall surface 102, as shown by the arrow in Fig. 8(b).

[0067] At this time, because the dimension W3 is shorter than the dimension W1, when the upper tongue 170 of the hook 138 is inserted into the engaging portion 150 of the hook receiver 144, the lower tongue 172 does not reach the engaging portion 152 as shown in Fig. 8(e). This allows the upper tongue 170 of the hook 138 to be securely engaged with the engaging portion 150 of the hook receiver 144. Therefore, even if the hook receivers 144, 146 of the shelf board 104 are difficult to see, the shelf 100 can be easily and securely attached to the hooks 138, 140 of the wall surface 102.

[0068] Fig. 9 is a diagram showing a state in which the shelf 100 in Fig. 8(c) receives an impact from below. When the shelf 100 receives an impact from below and is pushed up from below as shown by the arrows in Fig. 9(a) and Fig. 9(b), the lower tongue piece 172 of the hook 138 engages with the engagement portion 152 of the hook receiver 144.

[0069] At this time, since the dimension W2 is longer than the dimension W1, when the lower tongue 172 of the hook 138 engages with the engaging portion 152 of the hook receiver 144, the upper tongue 170 maintains engagement with the engaging portion 150 as shown in Figures 9(a) and 9(b). This makes it possible to prevent the shelf 100 from falling off the wall surface 102 even when the shelf 100 is pushed up from below due to an impact from below.

[0070] Although the preferred embodiment of the present invention has been described above with reference to the accompanying drawings, it goes without saying that the present invention is not limited to the above-described embodiment. It is clear that a person skilled in the art can think of various modifications or alterations within the scope of the claims, and it is understood that these also naturally belong to the technical scope of the present invention.
