Summary of the Invention

Problems to be Solved by the Invention

[0004] However, in the storage shelf described in Patent Document 1 above, the attachment and detachment of the shelf board by the shelf receiver to the shelf post are performed at the position of the side surface on the back side of the shelf board. Therefore, in the above-described storage shelf, the attachment and detachment portion between the shelf post and the shelf board is difficult to see. Further, in the above-described storage shelf, since the front portion of the shelf board on the side opposite to the attachment and detachment portion has to be held to operate the shelf board in the front-rear direction, there is a problem that it is not easy to attach and detach the shelf board.

[0005] Therefore, the main object of the present invention is to contribute to the improvement of the above-described problems.

Means for Solving the Problems

[0006] In response to the above problems, the present invention provides a shelf board having a rectangular shape in plan view, <00000^5>four shelf posts installed near each corner portion of the shelf board, <000?036>A storage shelf comprising shelf support brackets integrally attached to each corner of the shelf board, The shelf support has a locking hole on the shelf mounting surface facing the end face in the width direction of the shelf board. The aforementioned shelf brackets are A lower mounting portion fixed to the lower surface of the shelf board, The L-shaped metal fitting body has a side contact portion that abuts against the front or rear side of the shelf board, The metal fitting body extends outward from the side contact portion in the width direction of the shelf board. It has a hook portion that can be inserted into and locked into the locking hole. death, The side contact portion has a base portion of the hook portion that serves as a positioning portion in the width direction relative to the end face of the shelf board. A gap is formed between the shelf mounting surface of the shelf post and the end surface of the shelf, and the shelf support fitting is characterized in that the hook portion extends longer than the gap. [Effects of the Invention]

[0007] According to the present invention, the above configuration makes it possible to easily attach and detach the shelves. Furthermore, by using the base of the hook portion as the positioning portion on the side contact portion of the shelf bracket, the shelf bracket can be easily positioned and fixed to the shelf board.

Modes for Carrying Out the Invention

[0009] This embodiment will now be described in detail with reference to the drawings. Figures 1 to 17 illustrate this embodiment. Of these, Figures 1 to 14 represent Example 1, and Figures 15A to 17 represent Example 2. [Examples]

[0010] <Configuration>The configuration of this embodiment will be described below.

[0011] A storage shelf 1, as shown in Figure 1, is installed inside a building such as a house. The storage shelf 1 is a storage device for storing items and is equipped with shelves 2.

[0012] Here, the building can be made of any structure, such as wood, concrete, or steel. In this embodiment, the building is a modular building composed of multiple box-shaped building units.

[0013] Shelf board 2 is one of the components of the storage shelf 1, and is a horizontal side panel with a surface on which objects are placed. Shelf board 2 can be provided as a single unit or in multiple units at different heights.

[0014] To explain the directions, the horizontal direction connecting the front and back of storage shelf 1 is the depth direction X (or front-to-back direction). The horizontal direction in which shelf board 2 extends laterally toward the depth direction X is the width direction Y of storage shelf 1. The vertical direction in which multiple shelf boards 2 are installed is the height direction Z (or up-and-down direction) of storage shelf 1. The depth direction X, width direction Y, and height direction Z are perpendicular to each other. The height of shelf board 2 is determined by the position in the height direction Z where shelf board 2 is installed.

[0015] Then, as shown in Figures 2 (to 4), storage shelf 1 is installed using the building's wall.

[0016] A wall is a vertical surface located inside a building that divides the space within the building. Preferably, the wall on which the storage shelf 1 is installed has three surfaces: a back wall 3 that faces away from the viewer, and a pair of parallel side walls 4 located on both sides in the width direction Y, forming a storage space such as a closet. The side walls 4 are located on either side of the back wall 3 and face each other at a distance from each other.

[0017] Each wall (back wall 3, side walls 4) may be a panel-like structure having a panel frame 5 and a facing material 6 (Figure 1). The panel frame 5 is rectangular in shape, consisting of a pair of vertical frames 5a and a pair of horizontal frames 5b. The panel frame 5 has multiple horizontal bars 5c inside (between the vertical frames 5a) spaced apart in the height direction Z. The facing material 6 is approximately rectangular in shape and size to the panel frame 5 and is attached to one or both sides of the panel frame 5. The facing material 6 is attached to at least the inner surface of the panel frame 5 that faces the storage space. The storage space is also provided with a floor 7 and a ceiling.

[0018] In addition to the basic configuration described above, this embodiment may also include the following configuration.

[0019] (1a) Storage shelf 1 is As shown in Figure 5, the shelf board 2 has a rectangular shape in plan view, As shown in Figure 6 (Figure 7), four shelf supports 12 are installed near each corner 11 of the shelf board 2, The system includes shelf support brackets 13 that are integrally attached to each corner 11 of the shelf board 2, as shown in Figures 8 (to 11).

[0020] Here, the storage shelf 1 is a variable storage device that has a shelf board 2, shelf posts 12, and shelf support brackets 13, and allows the height of the shelf board 2 to be easily changed. The shelf board 2 and shelf posts 12 are formed to fit within the storage space described above. The storage capacity of the storage shelf 1 can be increased by making the shelf board 2 larger and the shelf posts 12 smaller.

[0021] The shelf board 2 (Figure 5) can be made of any material as long as the required strength and appearance quality are achieved. The shelf board 2, which is rectangular in plan view, has a top surface 2a and a bottom surface 2b, front and back side surfaces 2c in the depth direction X, and end surfaces 2d on both sides in the width direction Y. The top surface 2a and the bottom surface 2b are flat, horizontal surfaces. The side surfaces 2c are elongated, flat, vertical surfaces that extend linearly in the width direction Y. The end surfaces 2d are elongated, flat, vertical surfaces that extend linearly in the depth direction X.

[0022] Shelf board 2 is sized to fit between a pair of shelf posts 12 installed on both sides of the storage space in the width direction Y. In this embodiment, the storage space is wide enough to accommodate only one shelf board 2. That is, only one shelf board 2 is installed horizontally between a pair of shelf posts 12 that are spaced apart in the width direction Y.

[0023] The corner sections 11 are the four corners of the rectangular shelf board 2 in plan view. The corner sections 11 are formed at approximately right angles to the intersection of the side surface 2c and the end surface 2d of the shelf support 12.

[0024] The shelf support 12 (Figure 6) is a vertical member that constitutes the main body of the storage shelf 1 and supports the shelf board 2 at the required height. The shelf support 12 is designed to provide the necessary strength and appearance quality. The shelf board 2 is made of a material with a cross-sectional size similar to or smaller than that used in a typical storage shelf 1. The shelf support 12 is attached to the front and back sides of the wall that constitutes the storage space, on both sides of the wall in the width direction Y, with the shelf support 12 attached to the front and back sides in the depth direction X (Figure 2).

[0025] First, the four shelf supports 12 are positioned to form a rectangular shape when viewed in plan, so that they are adjacent to each other with a gap in the depth direction X, and spaced apart facing each other with a gap in the width direction Y, and are parallel to each other.

[0026] The four shelf supports 12 are fixed to each side wall 4 with respect to the depth direction X, at intervals that are approximately the same as or slightly wider than the depth direction X of the shelf board 2.

[0027] In this case, the shelf support 12 on the rear side may be installed slightly in front of the rear wall 3. This may create a gap (finger-insertion gap f, Figure 3) between the shelf board 2 (the rear side 2c) and the rear wall 3 for inserting a finger. The finger-insertion gap f can be set appropriately within the range of, for example, 15 mm to 25 mm. In this embodiment, the finger-insertion gap f is set to approximately 20 mm.

[0028] The four shelf supports 12 are installed opposite each other on the side walls 4 in the width direction Y, such that the distance between the opposing parts of the shelf supports 12 is slightly wider than the width direction Y dimension of the shelf board 2. This is the configuration when only one shelf board 2 is installed in the width direction Y.

[0029] The shelf support 12 may be formed to a length where its lower end reaches the floor 7, or it may be formed to a length where its lower end does not reach the floor 7. If the lower end does not reach the floor 7, the shelf support 12 is installed above the floor 7, with its lower end separated from the floor 7. The position of the lower end of the shelf support 12 is set, for example, at the height of the lowest shelf board 2 or slightly lower (lower end height h, Figure 3). This keeps the overall length of the shelf support 12 short.

[0030] The shelf support 12 (Figures 6 and 7) is a long member with a C-shaped cross-section, having a shelf mounting surface 12a to which the shelf board 2 is attached, and a pair of side portions 12b that extend parallel to each other and of the same length from both side edges of the shelf mounting surface 12a in the out-of-plane direction. The side portions 12b extend toward the side wall 4 to which it is attached.

[0031] The shelf support 12 is made of a metal member having a uniform cross-section, and the shelf mounting surface 12a and the side portion 12b have a substantially constant thickness t (Figure 7(c)) that is the same along their entire length. The shelf support 12 is hollow inside (the portion between the pair of side portions 12b).

[0032] The shelf support 12 has mounting holes 12c (round holes) formed through the shelf mounting surface 12a, and the shelf mounting surface 12a is attached to the side wall 4 almost perpendicularly by screws 14 (Figure 2) or the like through the mounting holes 12c.

[0033] The mounting holes 12c are provided at least near the upper and lower ends of the shelf post 12, in locations where there are panel frames 5 of the side wall 4 (such as vertical frames 5a, horizontal frames 5b, or horizontal rails 5c). This allows the shelf post 12 to be fixed to the panel frame 5 with screws 14.

[0034] The mounting holes 12c near the upper and lower ends of the shelf post 12 may be provided at different distances from the ends of the shelf post 12. By creating these differences in the distance of the mounting holes 12c from the ends, the shelf post 12 will have a distinction in its up and down orientation.

[0035] Additionally, the mounting holes 12c may be provided in the middle of the shelf support 12 as appropriate. The mounting holes 12c in the middle are provided at the position of the panel frame 5 of the side wall 4 (for example, the horizontal bar 5c). The mounting holes 12c are provided in a position that does not overlap with the locking holes 17.

[0036] In addition, end caps 15 (Figure 6) are attached to the upper and lower ends of the shelf support 12.

[0037] The shelf support 12 is installed against the side wall 4 with its shelf mounting surface 12a facing perpendicular to the width direction Y, and the shelf mounting surface 12a is fixed to the side wall 4 with screws 14 (Figure 2) approximately in the width direction Y. At this time, the side portion 12b of the shelf support 12 is oriented perpendicular to the depth direction X. The side portion 12b abuts against the side wall 4, and the shelf mounting surface 12a is oriented inward into the storage space and spaced apart from the side wall 4.

[0038] As a result, the size of the internal space of the hollow shelf post 12 in the width direction Y is equal to the length of the side portion 12b (post width w, Figure 7) excluding the thickness t of the shelf mounting surface 12a. Furthermore, the distance between opposing parts of the shelf posts 12 is equal to the distance between the surfaces of the opposing shelf mounting surfaces 12a of the opposing shelf posts 12.

[0039] The shelf support bracket 13 (Figure 8) is a fitting that is attached to the shelf board 2 to support the shelf board 2 on the shelf column 12. The shelf support bracket 13 is designed to provide the necessary strength and appearance quality. The shelf support bracket 13 is attached integrally to the shelf board 2 with screws 16. The shelf support bracket 13 is fixed to the shelf board 2 so as not to move relative to it. The shelf support bracket 13 in this embodiment has a structure that allows the height of the shelf board 2 to be changed without removing it from the shelf board 2. Two types of shelf support brackets 13 are provided, one with the left and one with the right-hand orientation opposite each other, as shown in Figures 9 and 10, respectively, and two of each are used so that the diagonal positions of the shelf board 2 are the same.

[0040] (1b) As shown in Figure 12, in storage shelf 1, The shelf support 12 has a locking hole 17 on the shelf mounting surface 12a that faces the end face 2d in the width direction Y of the shelf board 2. The shelf support bracket 13 has a hook portion 18 that extends in the width direction Y and can be inserted into and locked into the locking hole 17. Furthermore, a gap S is formed between the shelf mounting surface 12a of the shelf post 12 and the end surface 2d of the shelf board 2, and the hook portion 18 of the shelf support bracket 13 extends longer than the gap S.

[0041] Here, the shelf mounting surface 12a of the shelf post 12 is a vertical surface on the shelf post 12 that is perpendicular to the width direction Y on the side of the shelf board 2. The shelf mounting surface 12a partially faces the end face 2d on the same side of the shelf board 2 with a gap S between them. At least approximately half of one side of the locking hole 17 of the shelf mounting surface 12a faces a portion of the end face 2d of the shelf board 2. The front and back portions of the end face 2d of the shelf board 2 face a portion of the shelf mounting surface 12a in the depth direction X.

[0042] The locking hole 17 is a hole formed through the shelf mounting surface 12a of the shelf post 12 for receiving the hook portion 18. By inserting the tip of the hook portion 18 into the locking hole 17, the locking hole 17 holds the hook portion 18 in a locked state.

[0043] The locking hole 17 is a rectangular hole (vertical hole) that extends vertically and is large enough (height) to allow the hook portion 18 to be inserted and removed. The dimension of the locking hole 17 in the depth direction X (hole width) is approximately the same as or slightly wider than the plate thickness of the hook portion 18.

[0044] Multiple locking holes 17 are formed with intervals between them in the height direction Z. The upper and lower locking holes 17 are formed with appropriate intervals necessary for adjusting the height at which the shelf board 2 is installed. Between multiple shelf posts 12, the locking holes 17 are formed at the same height.

[0045] The hook portion 18 is a protruding part of the shelf support bracket 13 that extends outward in the width direction Y (towards the side wall 4). The hook portion 18 is inserted into the locking hole 17 and is locked and held in place by the locking hole 17. The shape and size of the hook portion 18 are such that they provide the necessary strength (load capacity) and locking condition for supporting the shelf board 2. The hook portion 18 will be described later.

[0046] The gap S is a space in the width direction Y that is formed between the shelf support 12 and the shelf board 2. The gap S is formed between the shelf board mounting surface 12a of the shelf support 12 and the end face 2d of the shelf board 2. The gap S allows the shelf board 2 to be mounted away from the shelf support 12 so as not to come into direct contact with the shelf support 12. The gap S is formed by shortening the width direction Y dimension of the shelf board 2. In addition, a larger gap space (compared to the gap S) is also formed between the middle portion of the end face 2d of the shelf board 2 and the side wall 4, but this gap space is different from the gap S described above.

[0047] The gap S is formed on one or both sides of the shelf board 2 in the width direction Y. When there are gaps S on both sides of the shelf board 2 in the width direction Y, the gaps S on both sides can be of different sizes or of the same size. In this embodiment, the gaps S on both sides are set to be of the same size. In this case, the storage shelf 1 has a symmetrical shape.

[0048] As described above, the end faces 2d of the shelf board 2 are the faces on both sides in the width direction Y of the shelf board 2, and face the shelf board mounting surface 12a of the shelf column 12 and the side wall 4.

[0049] (2) The shelf support brackets 13 (Figures 8 to 11) that are integrally attached to the corner portion 11 of the rectangular shelf board 2 in the above storage shelf 1 will be described below. The shelf support bracket 13 is A lower mounting portion 21 is fixed to the lower surface 2b of the shelf board 2, The device includes an L-shaped metal fitting body 23 having a side contact portion 22 that abuts against the front or rear side surface 2c of the shelf board 2. The metal fitting body 23 has a hook portion 18 that extends outward in the width direction Y of the shelf board 2 from the side contact portion 22.

[0050] Here, the lower surface 2b of the shelf board 2 is the side of the shelf board 2 that faces downwards in the height direction Z when the rectangular shelf board 2 is installed horizontally. The lower surface 2b of the shelf board 2 is a flat surface and serves as the mounting surface for the shelf support bracket 13. The shelf support bracket 13 is attached to the shelf board 2 with the lower surface 2b facing upwards.

[0051] The lower mounting portion 21 is the lateral surface (contact fixing surface) of the shelf support bracket 13, which is fixed in contact with the lower surface 2b of the shelf board 2. The lower mounting portion 21 of the shelf support bracket 13 is a flat surface.

[0052] The lower mounting portion 21 is provided with a through-hole 21a for the screw 16. The through-hole 21a may be a round hole, or it may be an elongated hole extending in the width direction Y.

[0053] The side surface 2c of shelf board 2 is the vertical surface of shelf board 2 that faces either the front or back side in the depth direction X when the rectangular shelf board 2 is installed horizontally. The side surface 2c of shelf board 2 is a flat surface with a certain height that is equal to the thickness of shelf board 2.

[0054] The side contact portion 22 is the vertical surface (contact locking surface) of the shelf support bracket 13, which is designed to lock into place in a near-contact state with the side surface 2c of the shelf board 2. The side contact portion 22 of the shelf support bracket 13 is a flat surface with a nearly constant height that is approximately the same as, or slightly lower than or higher than, the thickness of the shelf board 2.

[0055] In this embodiment, the side contact portion 22 rises from the bottom mounting portion 21 by approximately the thickness of the side surface 2c of the shelf board 2, so that the top surface 2a of the shelf board 2 and the upper edge of the side contact portion 22 are aligned at approximately the same position.

[0056] The metal fitting body 23 is the mounting portion of the shelf support fitting 13 to the shelf board 2, and has a bottom mounting portion 21 and a side contact portion 22 integrated together, so that it is approximately L-shaped when viewed from the width direction Y. The metal fitting body 23 may also be formed by bending the bottom mounting portion 21 and the side contact portion 22 at approximately a right angle. The metal fitting body 23 is installed so that it fits approximately between the top surface 2a and the bottom surface 2b of the shelf board 2 in the height direction Z by aligning the bottom mounting portion 21 and the side contact portion 22 along the bottom surface 2b and side surface 2c of the shelf board 2. The metal fitting body 23 may be rounded in various parts as needed.

[0057] The hook portion 18 is the locking portion of the shelf support fitting 13 to the shelf post 12 and is integrally formed with the fitting body 23. The hook portion 18 extends outward in the width direction Y from the side of the shelf post 12 of the side contact portion 22, or from the outer edge portion in the width direction Y (outer end edge portion), toward the shelf mounting surface 12a of the shelf post 12, and extends beyond the shelf mounting surface 12a. As a result, the total length of the hook portion 18 in the width direction Y (hook length L) is longer than the gap S between the shelf post 12 and the shelf 2 (gap S < hook length L). The hook length L is set to be shorter than the length that reaches the side wall 4. The hook portion 18 is also set to have a vertical surface that is flush with the side contact portion 22. The hook portion 18 is formed so as to fit approximately between the upper surface 2a and the lower surface 2b of the shelf 2 in the height direction Z.

[0058] (3) With the shelf support bracket 13 described above, The side contact portion 22 may also have the base of the hook portion 18 as a positioning portion 22a in the width direction Y relative to the end face 2d of the shelf board 2.

[0059] Here, the base of the hook portion 18 is the starting point of the hook portion 18 extending from the side contact portion 22. That is, the outer edge (outer end edge portion) of the side contact portion 22 in the width direction Y becomes the base of the hook portion 18.

[0060] The end face 2d of the shelf board 2 is the vertical surface of the shelf board 2 that faces both sides in the width direction Y when the rectangular shelf board 2 is installed horizontally. The end face 2d of the shelf board 2 is a flat surface with a certain height which is the thickness of the shelf board 2. The end face 2d of the shelf board 2 faces (partially) the shelf board mounting surface 12a of the shelf column 12 with a gap S between them.

[0061] The positioning section 22a is provided to accurately determine the mounting position of the shelf support bracket 13 in the width direction Y relative to the shelf board 2 when attaching the shelf support bracket 13 to the shelf board 2. By aligning the positioning section 22a with the end face 2d of the shelf board 2 and attaching the shelf support bracket 13 to the shelf board 2, the shelf support bracket 13 is fixed in a position that is accurately positioned in the width direction Y relative to the shelf board 2.

[0062] The positioning portion 22a is formed at the boundary between the base of the hook portion 18 and the side contact portion 22. In other words, the outer edge (outer end edge portion) of the side contact portion 22 becomes the positioning portion 22a.

[0063] In this embodiment, the shelf support bracket 13 extends the side contact portion 22 further outward in the width direction Y than the bottom mounting portion 21, forming a width-enlarged portion 22b, and a positioning portion 22a is formed on the outer edge of the width-enlarged portion 22b. Due to the width-enlarged portion 22b, the outer edge of the bracket body 23 has a stepped shape between the side contact portion 22 and the bottom mounting portion 21.

[0064] The side contact portion 22 has a hook portion 18 formed on the upper side of its outer edge and a positioning portion 22a formed on the lower side. The positioning portion 22a extends in the height direction Z.

[0065] (4) With the shelf support bracket 13 described above, The hook portion 18 has an extended portion 31 that extends toward the shelf column 12, which is installed with a gap S between it and the end face 2d of the shelf board 2, and is the same length as or longer than the gap S. The extension portion 31 may also have a claw portion 32 formed at its tip, which can be inserted into and locked into a locking hole 17 formed on the shelf mounting surface 12a of the shelf post 12 that faces the end face 2d of the shelf board 2.

[0066] Here, as shown in Figure 9, the extension portion 31 is an elongated part that extends approximately in the width direction Y from the base of the hook portion 18 toward the claw portion 32 at the tip, and is formed between the side contact portion 22 and the claw portion 32 of the shelf support fitting 13. The extension portion 31 functions as a movement range L1 for moving the shelf board 2 in the width direction Y when attaching or detaching the shelf board 2 to the shelf column 12. The movement of the shelf board 2 in the width direction Y is made possible by the presence of a gap S between the shelf column 12 and the shelf board 2. The amount of movement of the shelf board 2 is determined by the size of the gap S in the width direction Y and the length of the side portion 12b of the shelf column 12 (column width w) in the width direction Y.

[0067] Furthermore, the extension portion 31 can function even if it is only provided on the hook portion 18 of the shelf support bracket 13 installed on one side in the width direction Y of the shelf board 2. In this case, the gap S is formed on the side of the shelf support bracket 13 on which the extension portion 31 is provided. The hook portion 18 on the side without the extension portion 31 has a base length that is approximately equal to the thickness t of the shelf board mounting surface 12a with respect to the width direction Y.

[0068] The claw portion 32 is a hook-shaped projection that extends downward from the tip of the extended portion 31. In this embodiment, the claw portion 32 has a width (claw width L2) that is almost uniform with respect to the width Y and extends in the height Z (almost vertically downward). The claw portion 32 may be of any length (total height H), but it may be formed to a length that does not reach the lower surface 2b of the shelf board 2 so that it fits between the upper surface 2a and the lower surface 2b of the shelf board 2.

[0069] Furthermore, the portion of the claw portion 32 that is below the position of the lower edge portion 31a of the extended portion 31 becomes the claw engagement portion that catches on the lower edge portion 17a (Figure 6) of the locking hole 17. The claw engagement portion of the claw portion 32 is set to a length H1 that securely locks onto the locking hole 17.

[0070] Furthermore, the hook portion 18 is formed such that the upper edges of the extended portion 31 and the claw portion 32 smoothly connect with the upper edge of the side contact portion 22. The upper edge of the side contact portion 22 is made to be a nearly horizontal straight line.

[0071] The upper edge of the hook portion 18 may, for example, be connected to the upper edge of the side contact portion 22 and extended almost horizontally at the same height. Alternatively, the upper edge of the hook portion 18 may be bent from the upper edge of the side contact portion 22 and inclined downwards toward the tip.

[0072] In either of the above cases, the hook portion 18 may have a chamfered portion 18a, such as a sloping portion or a rounded portion, on the tip side of its upper edge. The chamfered portion 18a is formed over a relatively wide area, extending from the upper side of the claw portion 32 to a part of the tip side of the extension portion 31. The chamfered portion 18a facilitates the entry and exit of the hook portion 18 into the locking hole 17. In this embodiment, the chamfered portion 18a is a rounded portion.

[0073] The following explains the dimensions.

[0074] The claw width L2 of the claw portion 32 is set to a dimension greater than the minimum required to obtain the strength (load capacity) and locking condition necessary to support the shelf board 2. The minimum dimension of the claw width L2 can be obtained by strength calculation.

[0075] The column width w of the shelf support 12 is set to be greater than twice the claw width L2 (2·(claw width L2) ≤ column width w). The column width w can be obtained from the claw width L2 or the standard dimensions of shelf support 12 that are commonly used.

[0076] The gap S between shelf board 2 and shelf support 12 is set to be larger than the claw width L2 (claw width L2 ≤ gap S). The gap S can be determined from the claw width L2 and the standard dimensions of shelf board 2 that are commonly used.

[0077] Note that if the column width w and gap S are made too large, the shelf board 2 will become smaller, reducing storage capacity, so it is best to set them to the minimum size possible.

[0078] The length of the extension 31 in the width direction Y (movement range L1) is, for example, the sum of the gap S and the thickness t of the shelf column 12, with a slight margin of error, or larger. The extension 31 can be extended to a length where the claw portion 32 reaches the side wall 4 when the claw portion 32 is released from the locking hole 17 (gap S + thickness t < movement range L1 < gap S + thickness t + column width w - 2 * (claw width L2)).

[0079] Furthermore, the height dimension (hole height) of the locking hole 17 in the height direction Z is set to a size that does not connect with the upper and lower locking holes 17. The hole height of the locking hole 17 is set to a size that is slightly larger than the sum of the total height H of the claw portion 32 and the downward length H1 of the claw engagement portion 32 (total height H + length H1 < hole height).

[0080] (5) With the shelf support bracket 13 described above, The hook portion 18 has a stopper portion 41 at the lower edge portion 31a on the tip side of the extended portion 31, and the stopper portion 41 may be in the shape of an upwardly convex arc.

[0081] Here, the lower edge 31a of the extension 31 is the lower edge of the extension 31. When the shelf board 2 is attached to the shelf post 12, the hook portion 18 is inserted into the locking hole 17, and the lower edge 31a of the extension 31 is placed on the lower edge 17a (Figure 6) of the locking hole 17 in a nearly point contact state. When the shelf board 2 is moved in the width direction Y, the contact position of the lower edge 31a of the extension 31 with respect to the lower edge 17a of the locking hole 17 is displaced in the width direction Y. That is, the extension 31 moves while its lower edge 31a rubs against the lower edge 17a of the locking hole 17. The extension 31 is made to be in a nearly horizontal straight shape except for the stopper portion 41 of the lower edge 31a.

[0082] The stopper portion 41 is formed on the hook portion 18 and stops the movement of the shelf board 2 when it moves in the width direction Y relative to the shelf column 12. The stopper portion 41 may also stop the movement of the shelf board 2 by aligning with the locking hole 17.

[0083] The stopper portion 41 may have any shape or structure. Furthermore, the stopper portion 41 may be provided on any part of the hook portion 18, but in this embodiment, it is provided on the extension portion 31. The stopper portion 41 may be formed on either the upper edge or the lower edge 31a of the extension portion 31 on the hook portion 18. In this embodiment, the stopper portion 41 is provided on the lower edge 31a of the extension portion 31. By forming the stopper portion 41 on the lower edge 31a of the extension portion 31, the stopper portion 41 becomes inconspicuous from the outside. Additionally, the stopper portion 41 on the lower edge 31a directly stops the movement of the contact position of the lower edge 31a of the extension portion 31 with respect to the lower edge 17a of the locking hole 17, thereby restricting the movement of the hook portion 18 in the width direction Y and stopping the shelf board 2.

[0084] Furthermore, the stopper portion 41 is formed on the lower edge portion 31a of the extended portion 31, close to the claw portion 32. The stopper portion 41 can have any shape, such as a convex or concave portion, but in this embodiment, the stopper portion 41 is a notched portion that is convex upwards in the shape of an arc.

[0085] By making the stopper portion 41 an upwardly convex notch, when the stopper portion 41 reaches the position of the lower edge portion 17a of the locking hole 17, the lower edge portion 17a of the locking hole 17 and the stopper portion 41 will fit together. Alternatively, when the stopper portion 41 reaches the position of the lower edge portion 17a of the locking hole 17, the hook portion 18 will fall in.

[0086] Then, when the stopper portion 41 fits into the lower edge portion 17a of the locking hole 17, the movement of the hook portion 18 in the width direction Y is stopped. The hook portion 18 stops at approximately the top of the stopper portion 41. At this time, the claw portion 32 is substantially locked to the inner surface of the locking hole 17 in the width direction Y. In addition, by making the stopper portion 41 an upwardly convex arc shape, the stopper portion 41 can be removed from the locking hole 17 in the easiest and smoothest way possible.

[0087] Furthermore, the stopper portion 41 can function even if it is only provided on one of the extension portions 31, relative to the shelf support brackets 13 which are provided on both sides in the width direction Y of the shelf board 2.

[0088] The following describes the dimensional relationship of the stopper portion 41.

[0089] It is preferable that the stopper portion 41 is designed to be easily fitted into the locking hole 17 and easily disengaged from the locking hole 17.

[0090] To this end, the width dimension Y of the stopper portion 41 (stopper width L3) is set to be greater than or equal to the thickness t of the shelf column 12. To allow for some margin, the stopper width L3 may be at least 2 to 3 times the thickness t of the shelf column 12. Also, the stopper width L3 is set to be less than or equal to half the length Y of the extension portion 31 (movement range L1) (2·(thickness t) < stopper width L3 < 1 / 2(movement range L1)). In this case, the movement range L1 may be, for example, the length of the portion excluding the stopper width L3, which may be an intermediate size between the claw width L2 and the gap S.

[0091] Furthermore, the depth of the stopper portion 41 (stopper depth H2) should be set within a range of about half to twice the thickness t of the shelf post 12, so as not to be too deep or too shallow relative to the lower edge 17a of the mating locking hole 17.

[0092] Furthermore, the stopper portion 41 is set to have a larger radius of curvature within the range of the stopper width L3 and stopper depth H2. This reduces the snagging of the lower edge 17a of the locking hole 17 at the boundary between the stopper portion 41 and the portion other than the stopper portion 41 at the lower edge 31a of the extended portion 31.

[0093] <effect>

[0094] First, we will explain how to attach the shelf board 2 to the shelf support 12.

[0095] First, as shown in Figure 13(a), the shelf board 2 is tilted so that one end face 2d in the width direction Y (left side in the figure) is lower and the other end face 2d is higher, and the shelf board 2 is inserted between the shelf posts 12 on both sides in the width direction Y, starting from the front side in the depth direction X.

[0096] Then, the shelf support bracket 13 attached to the corner portion 11 of the lowered end face 2d of the shelf board 2 inserts its hook portion 18 almost to the base into the locking hole 17 of the shelf post 12 on the same side (Figure 14(a)). At this time, with the shelf board 2 tilted, the hook portion 18 of the shelf support bracket 13 attached to the corner portion 11 of the higher end face 2d of the other side is positioned on the upper side outside the locking hole 17 of the shelf post 12 on the same side (Figure 14(b)).

[0097] Next, as shown in Figure 13(b), the shelf board 2 is gradually lowered at the other end face 2d until it is at approximately the same height as the locking hole 17 of the shelf post 12 on the same side.

[0098] Next, as shown in Figure 13(c), the shelf board 2 is moved approximately in the width direction Y from one side to the other, and the hook portion 18 of the shelf support bracket 13 attached to the corner portion 11 of the other end face 2d is inserted into the locking hole 17 of the shelf post 12 on the same side.

[0099] At this time, the hook portion 18 of the shelf support bracket 13 attached to the corner portion 11 of the end face 2d on one side moves toward the tip side of the extension portion 31, where it contacts the locking hole 17 of the shelf post 12 on the same side, and the lower edge portion 17a of the locking hole 17 and the stopper portion 41 of the extension portion 31 fit together. Almost simultaneously, the claw portion 32 on one side is almost locked to the inner surface of the locking hole 17. As a result, the movement of the hook portion 18 on one side in the width direction Y is stopped, and the claw portion 32 is stably locked and held in the locking hole 17.

[0100] Finally, as shown in Figure 13(d), with the other hook portion 18 inserted into the locking hole 17 of the shelf post 12 on the same side, the shelf board 2 is rotated downward around the position of the stopper portion 41 of the one hook portion 18, gradually lowering the other end face 2d of the shelf board 2 and making the shelf board 2 horizontal. This locks and holds the other hook portion 18 in the locking hole 17 of the shelf post 12 on the same side.

[0101] At this time, the hook portion 18 of the shelf support bracket 13 attached to the corner portion 11 of the other end face 2d has its lower edge portion 17a of the locking hole 17 directly fitted into the stopper portion 41 of the extension portion 31. In addition, the claw portion 32 on the other side is almost locked to the inner surface of the locking hole 17. As a result, the stopper portion 41 of the other side of the hook portion 18 restricts the movement of the hook portion 18 in the width direction Y, and the claw portion 32 is stably locked and held in the locking hole 17.

[0102] As described above, the shelf board 2 is attached to the shelf support 12. The shelf board 2 is then stopped in the width direction Y by the stopper part 41 in a highly stable manner.

[0103] Next, we will explain how to remove the shelf board 2 from the shelf support 12. In this case, you will perform almost the opposite operation to the one described above.

[0104] Specifically, as shown in Figure 13(d), the shelf board 2 is horizontal, and the hook portions 18 on both sides in the width direction Y are inserted into the locking holes 17. At this time, in each locking hole 17, the stopper portion 41 of the extended portion 31 of the hook portion 18 fits into the lower edge portion 17a of the locking hole 17, and the claw portion 32 is almost locked to the inner surface of the locking hole 17, so that the shelf board 2 is in a stable state.

[0105] From this stable position, slightly lift shelf 2 upwards, as shown in Figure 13(c). Due to balance constraints, it is difficult to lift shelf 2 perfectly horizontally unless you consciously try to do so. Therefore, if you lift it unconsciously, one side will naturally lift first, resulting in a slightly tilted position. This tilted position of shelf 2 actually helps you understand its movement and how to move it, allowing you to intuitively understand how to remove shelf 2.

[0106] Therefore, for example, as shown in the diagram, the shelf board 2 is first lifted so that the other side is higher, and then removed from the shelf support 12.

[0107] At this time, with the other hook portion 18 inserted into the locking hole 17 of the shelf post 12 on the same side, the shelf board 2 is rotated upward around the position of the stopper portion 41 of the one hook portion 18, gradually raising the other end face 2d of the shelf board 2 and tilting the shelf board 2. The shelf post 12 is raised to a maximum height where the other hook portion 18 touches the upper edge 17b (Figure 6) of the locking hole 17 of the shelf post 12 on the same side. As a result, the locking and holding state of the other hook portion 18 in relation to the locking hole 17 of the shelf post 12 on the same side is released.

[0108] At this time, the hook portion 18 of the shelf support bracket 13 attached to the corner portion 11 of the other end face 2d moves upward from the lower edge portion 17a of the locking hole 17, and the stopper portion 41 of the extension portion 31 floats away from the locking hole 17. As a result, the lower end of the claw portion 32 becomes higher than the lower edge portion 17a of the locking hole 17. This releases the restriction on movement in the width direction Y by the stopper portion 41 of the other hook portion 18.

[0109] Next, as shown in Figure 13(b), the shelf board 2 is moved (as if being pushed) from one side to the other side in approximately the width direction Y, while remaining in an inclined position, so that the hook portion 18 of the shelf support bracket 13 attached to the corner portion 11 of the other end face 2d comes out of the locking hole 17 of the shelf post 12 on the same side.

[0110] At this time, the hook portion 18 of the shelf support bracket 13 attached to the corner portion 11 of one end face 2d is moved in the width direction Y such that the lower edge portion 17a of the locking hole 17 is engaged with the stopper portion 41 of the extension portion 31, and the stopper portion 41 is disengaged. At this time, the contact position between the lower edge portion 31a of the extension portion 31 and the lower edge portion 17a of the locking hole 17 of the shelf post 12 on the same side moves towards the base of the hook portion 18.

[0111] This allows the hook portion 18 on one side to move in the width direction Y, and the claw portion 32 to be inserted deep into the locking hole 17. The shelf board 2 can move until the hook portion 18 on one side abuts against the back (side wall 4) of the shelf post 12 on the same side, or until the end face 2d on one side of the shelf board 2 abuts against the shelf board mounting surface 12a of the shelf post 12 on the same side.

[0112] In this case, for example, suppose the stopper portion 41 is a projection extending downward from the lower edge portion 31a of the extension portion 31. In this case, the locking hole 17 cannot be easily removed from the stopper portion 41 by lateral movement of the hook portion 18 alone. Alternatively, suppose the stopper portion 41 is a convex, angular notch formed on the lower edge portion 31a of the extension portion 31. In this case, a relatively large corner is formed at the boundary between the notch and the remaining part of the lower edge portion 31a, causing snagging or other issues between the notch and the lower edge portion 17a of the locking hole 17, making it difficult to remove the locking hole 17 from the stopper portion 41 by lateral movement of the hook portion 18.

[0113] In this embodiment, the stopper portion 41 is shaped like an upward-convex arc to reduce snagging. As a result, the locking hole 17 can be easily and smoothly released from the stopper portion 41 simply by moving the hook portion 18 laterally.

[0114] The lifting and lateral movement of shelf board 2 described above may be performed simultaneously.

[0115] Then, as shown in Figure 13(a), the shelf board 2 is raised on the other side so that the hook portion 18 protruding from the locking hole 17 is higher than the locking hole 17.

[0116] Finally, the shelf board 2 is lifted further on the other side, gradually increasing its tilt. This creates a gap between the tip of the hook portion 18 on the other side and the shelf board mounting surface 12a of the shelf post 12 on the same side that is greater than the total length of the hook portion 18 (hook length L). After that, or simultaneously, the shelf board 2 is moved to the other side, allowing the hook portion 18 of the shelf support bracket 13 attached to the corner portion 11 of the end face 2d on one side of the shelf board 2 to exit the locking hole 17 of the shelf post 12 on the same side. At this time, small movements of moving the shelf board 2 to the other side by a small amount by the amount of the gap created between the shelf board 2 and the shelf post 12 by lifting the shelf board 2 may be performed continuously or discontinuously.

[0117] Then, the shelf board 2 is tilted so that one end face 2d in the width direction Y is lower and the other end face 2d is higher, and with the hook portions 18 on both sides protruding from the locking holes 17, the shelf board 2 is pulled out from between the shelf posts 12 on both sides in the width direction Y toward the front in the depth direction X. In this way, the shelf board 2 is removed from the shelf posts 12.

[0118] The installation and removal of shelf board 2 can be performed smoothly without removing the shelf support bracket 13 from shelf board 2. Furthermore, the height of shelf board 2 can be easily changed by performing the installation and removal procedures described above as needed.

[0119] In all of the above cases, creating a gap (finger gap f) between the shelf board 2 and the back wall 3 makes it easier to install and remove the shelf board 2.

[0120] <Effects>According to this embodiment, the following effects can be obtained.

[0121] (Effect 1) The storage shelf 1 may also consist of a shelf board 2, shelf posts 12, and shelf support brackets 13. This simplifies the structure of the storage shelf 1.

[0122] Then, a total of four shelf support brackets 13 are attached to each corner 11 of the shelf board 2, and the shelf support brackets 13 at each corner 11 of the shelf board 2 are held by the four shelf posts 12. As a result, all corners 11 of the shelf board 2 are supported by the shelf posts 12. Therefore, the storage shelf 1 can withstand a large load (or the load capacity of the shelf board 2 can be increased).

[0123] In this process, the shelf board 2 is installed on the shelf post 12 by inserting and locking the hook portion 18 of the shelf support bracket 13, which is integrally attached to the end face 2d of the shelf board 2, into the locking hole 17 formed in the shelf board mounting surface 12a of the shelf post 12. The height of the shelf board 2 can then be changed by inserting and locking the hook portion 18 into locking holes 17 of different heights.

[0124] The storage shelf 1 has a gap S (in the width direction Y) between the shelf mounting surface 12a of the shelf post 12 and the end surface 2d of the shelf board 2. This gap S allows the shelf board 2 to be moved in the width direction Y relative to the shelf post 12 by the amount of the gap S. Furthermore, by using the movement of the shelf board 2 to release the locking state between the hook portion 18 of the shelf support bracket 13 and the locking hole 17 of the shelf post 12, it becomes possible to directly attach and detach the shelf board 2 to the shelf post 12 without removing the shelf support bracket 13 from the shelf board 2. Therefore, attaching and detaching the shelf board 2 for height changes, etc., can be done easily without using tools. In addition, since the shelf support bracket 13 does not need to be removed from the shelf board 2, loss of the shelf support bracket 13 can be prevented.

[0125] The storage shelf 1 has a gap S (in the width direction Y) between the shelf mounting surface 12a of the shelf column 12 and the end surface 2d of the shelf 2. This allows the engagement point between the hook portion 18 extending from above in the width direction Y and the locking hole 17 to be directly visible through the gap S. This enables work while visually inspecting the shelf, thus improving the workability when attaching and detaching the shelf 2. The gap S does not need to be large; it can be made small enough to be inconspicuous unless consciously looked at. In addition, the shelf support bracket 13 has a hook portion 18 that is of an appropriate length greater than the gap S in the width direction Y, making it easier to manipulate the shelf 2 when attaching and detaching it. Thus, the storage shelf 1 can be made more detachable.

[0126] The shelf support 12 may also be attached to the wall (side wall 4), which allows the shelf support 12 to be made into a minimal shape and size. Alternatively, the rear shelf support 12 may be installed slightly in front of the wall (back wall 3) to create a gap (finger gap f) between the rear side 2c of the shelf board 2 and the wall. By creating a finger gap f in this way, when attaching or detaching the shelf board 2, it becomes possible to insert a finger into the gap S between the rear side 2c of the shelf board 2 and the wall and directly grasp the shelf board 2 with the fingers. Therefore, the operation of the shelf board 2 when attaching or detaching it becomes easier (or the ease of attaching and detaching the shelf board 2 can be improved). Since the attachment and detachment of the shelf board 2 mainly involves movement in the width direction Y of the shelf board 2, being able to hold both the rear side 2c and the front side 2c of the shelf board 2 makes it easier to attach and detach the shelf board 2 compared to when the rear side 2c cannot be held.

[0127] (Effect 2) The shelf support bracket 13 may also include an L-shaped bracket body 23 having a bottom mounting portion 21 and a side contact portion 22. This allows the side contact portion 22 to contact the front or back side 2c of the shelf board 2, preventing rotation, so that the bottom mounting portion 21 can be fixed to the bottom surface 2b of the shelf board 2 with a single screw 16. Furthermore, if the insertion hole 21a for the screw 16 provided in the bottom mounting portion 21 is an elongated hole extending in the width direction Y, it becomes possible to finely adjust the mounting position of the shelf support bracket 13 with respect to the shelf board 2 in the width direction Y.

[0128] The L-shaped bracket body 23 has a horizontal lower mounting portion 21 and a vertical side contact portion 22 that is bent upward from the lower mounting portion 21. The bracket body 23 is installed so that the lower mounting portion 21 follows the lower surface 2b of the shelf board 2 and the side contact portion 22 follows the side surface 2c of the shelf board 2. As a result, the bracket body 23 is attached to the shelf board 2 with virtually no out-of-plane protrusion beyond the thickness of the shelf board relative to the outer shape of the shelf board 2. Furthermore, the bracket body 23 can be formed so that the side contact portion 22 fits within the height range of the shelf board 2.

[0129] Furthermore, by extending the hook portion 18 outward in the width direction Y from the side contact portion 22, the hook portion 18 becomes a vertical surface, making it possible to install it so that it fits within the height range of the shelf board 2.

[0130] Therefore, the shelf bracket 13 is almost integrated with the shelf board 2 in appearance, and the overall height is also reduced. As a result, the shelf bracket 13 can be attached to the shelf board 2 in an aesthetically pleasing and inconspicuous manner. Other aspects are the same as (Effect 1).

[0131] (Effect 3) In the shelf bracket 13, the side contact portion 22 may have the base of the hook portion 18 as the positioning portion 22a. Therefore, by simply aligning the base of the hook portion 18 with the end face 2d of the shelf board 2, the base of the hook portion 18 becomes a positioning marker (positioning portion 22a), and the shelf bracket 13 is accurately positioned. Thus, the shelf bracket 13 does not require measuring, marking, or drilling pilot holes for positioning. As a result, the shelf bracket 13 can be easily positioned and fixed to the shelf board 2.

[0132] In this case, the side contact portion 22 may have a hook portion 18 formed on the upper side of the outer edge and a positioning portion 22a on the lower side. This allows the positioning portion 22a to be on the upper side when, for example, the shelf board 2 is turned upside down and the shelf support bracket 13 is attached, making the positioning portion 22a easier to see and the shelf support bracket 13 easier to attach. Furthermore, when the shelf board 2 is attached to the shelf column 12, the hook portion 18 is on the upper side, making the hook portion 18 easier to see from above. As a result, the work can be done while visually checking the hook portion 18, improving the workability when attaching and detaching the shelf board 2.

[0133] Furthermore, by providing a positioning portion 22a on the outer edge of the side contact portion 22 and extending the hook portion 18 from the position of the positioning portion 22a, the length of the part of the hook portion 18 that functions when attaching or detaching the shelf board 2 becomes clear. Therefore, it becomes easy to set the hook portion 18 to the optimal length that matches the gap S between the shelf column 12 and the end face 2d of the shelf board 2. Alternatively, if there is a gap S between the shelf column 12 and the end face 2d of the shelf board 2, clearly separating the positioning portion 22a and the hook portion 18 extending from the positioning portion 22a makes it easy to set the gap S. Thus, the design of the storage shelf 1 also becomes easier.

[0134] (Effect 4) In the shelf bracket 13, the hook portion 18 may have an extension portion 31 and a claw portion 32. When the hook portion 18 is inserted into the locking hole 17, the claw portion 32 at the tip of the extension portion 31 and a part of the tip side of the extension portion 31 enter the locking hole 17. At this time, the extension portion 31 rests on the lower edge portion 17a of the locking hole 17 in a state of almost point contact. When the hook portion 18 is moved inside the locking hole 17, the lower edge portion 31a of the extension portion 31 shifts laterally, and the position of point contact is displaced in the width direction Y.

[0135] Furthermore, by extending the extension portion 31 to be the same length as or longer than the gap S, it can be used as a movement allowance L1 for moving the shelf board 2 in the width direction Y when attaching or detaching the shelf board 2. In addition, by extending the extension portion 31 to be longer than the gap S, a movement allowance L1 greater than the size of the gap S can be obtained, allowing for ample adjustment of the mounting position of the shelf support bracket 13 in the width direction Y relative to the shelf board 2.

[0136] Furthermore, the claw portion 32 enters the locking hole 17 and catches on the locking hole 17 from the inside of the shelf post 12, preventing it from coming loose. Therefore, the hook portion 18 can be securely inserted and locked into the locking hole 17 of the shelf post 12.

[0137] (Effect 5) In the shelf support bracket 13, the hook portion 18 may have a stopper portion 41 on the lower edge portion 31a of the claw portion 32 side of the extension portion 31. This allows the hook portion 18 to be moved in the width direction Y relative to the locking hole 17, and the stopper portion 41 to come to the position of the lower edge portion 17a of the locking hole 17, thereby stopping the movement of the hook portion 18 between the lower edge portion 17a of the locking hole 17 and the stopper portion 41. As a result, the stopper portion 41 restricts the movement of the shelf board 2 in the width direction Y, and the shelf board 2 is reliably stopped and stabilized at the position of the stopper portion 41, so that the fixed position of the shelf board 2 when installed is ensured by the stopper portion 41. In addition, the forced stopping by the stopper portion 41 creates a sense of determination, making it intuitively clear that the shelf board 2 has been stabilized in its fixed position. Thus, the shelf board 2 can be correctly installed on the shelf column 12.

[0138] In this case, the stopper portion 41 is made into an upwardly convex arc shape. As a result, the lower edge portion 17a of the locking hole 17 and the stopper portion 41 fit together, stopping the movement of the hook portion 18. Furthermore, the stopped state of the shelf board 2 by the stopper portion 41 is highly stable.

[0139] Furthermore, by optimally setting the curvature, depth, and width of the upward-convex arc-shaped stopper portion 41, the lower edge 17a of the locking hole 17 does not catch more strongly than necessary. As a result, the upward-convex arc-shaped stopper portion 41 can be released relatively easily when moving the shelf board 2 from a stable position in the width direction Y. Thus, the upward-convex arc-shaped stopper portion 41 does not unnecessarily hinder the movement of the shelf board 2 in the width direction Y when attaching or detaching the shelf board 2.

[0140] When the shelf board 2 is moved in the width direction Y, the contact position of the extension 31 with respect to the locking hole 17 shifts from the upwardly convex arc-shaped stopper portion 41 on the lower edge 31a of the extension 31 to another portion. At this time, the position of the hook portion 18 rises slightly, and the tilt of the shelf board 2 changes slightly. As a result, the status of the hook portion 18 and how to move the shelf board 2 can be naturally understood by the change in the tilt of the shelf board 2, so that the storage shelf 1 allows for intuitive attachment and detachment of the shelf board 2.

[0141] Furthermore, since the hook portion 18 has a stopper portion 41, the mounting position of the shelf support bracket 13 can be adjusted more accurately by using the stopper portion 41. That is, when attaching the shelf support bracket 13 to the shelf board 2, the stopper portion 41 and the lower edge portion 17a of the locking hole 17 are aligned at the position that should be the fixed position on the shelf board 2. This ensures that the shelf support bracket 13 is correctly attached to the shelf board 2. The mounting position of the shelf support bracket 13 to the shelf board 2 can be easily adjusted using the insertion hole 21a (elongated hole) of the lower mounting portion 21. [Examples]

[0142] Figures 15A to 17 illustrate Example 2.

[0143] In this embodiment, the storage space is wide enough to accommodate multiple shelves 2 installed side-by-side in the width direction Y. That is, multiple shelves 2 can be installed side-by-side between the shelf posts 12 attached to the side walls 4 on both sides in the width direction Y. In this case, the shelves 2 that are adjacent to each other in the width direction Y may be installed flush with the surface at the same height, or they may be installed at different heights in a staggered manner. The same shelves 2 and shelf support brackets 13 as in Embodiment 1 are used.

[0144] When two or more shelves 2 are installed side by side in the width direction Y, the four shelf supports 12 described above are installed at intervals in the depth direction X that are approximately the same as or slightly wider than the depth dimension of the shelves 2. In addition, in the width direction Y, the four shelf supports 12 are installed parallel to the side wall 4 at intervals wider than the combined width dimension of the multiple shelves 2.

[0145] Furthermore, between the shelves 2 that are adjacent to each other in the width direction Y, for example, two shelf posts 12, or a hollow intermediate shelf post 51 (Figure 17) that combines the same function as two shelf posts 12 into one, is installed. The two shelf posts 12 or the intermediate shelf post 51 are installed in pairs with approximately the same spacing as the shelf posts 12 in the depth direction X.

[0146] For example, when using two shelf supports 12, they are installed back-to-back so that the shelf mounting surfaces 12a face opposite each other in the width direction Y. The shelf supports 12 are of a length that reaches the floor 7 at their lower ends. In this case, the storage shelf 1 is separated into multiple sections in the width direction Y, each becoming independent.

[0147] On the other hand, when using the intermediate shelf support 51 as in this embodiment, the intermediate shelf support 51 is selected to provide the necessary strength and appearance quality. By using the intermediate shelf support 51, the storage shelf 1 is integrated as a single unit in the width direction Y. The intermediate shelf support 51 functions almost the same as the two shelf supports 12 described above as a second shelf support.

[0148] The intermediate shelf support 51 has shelf mounting surfaces 12a on both sides in the width direction Y, and each shelf mounting surface 12a has a locking hole 17 for attaching the shelf 2. The locking holes 17 of the intermediate shelf support 51 are formed in the same position and of the same size as the locking holes 17 of the shelf support 12 of the side wall 4 (hereinafter referred to as the first shelf support 12).

[0149] The intermediate shelf post 51 may be made of, for example, a C-shaped cross section member with a lip. The front surface of the intermediate shelf post 51 in the depth direction X is a side surface 12d that corresponds to the side surface 12b of the first shelf post 12. The width direction Y dimension (intermediate post width w1) of the side surface 12d of the intermediate shelf post 51 may be approximately the same as the side surface 12b of the first shelf post 12. In this case, the movement of the hook portion 18 in the width direction Y for attaching and detaching the shelf board 2 is mainly performed by the shelf post 12 on the opposite side in the width direction Y. In the intermediate shelf post 51, the movement of the hook portion 18 in the width direction Y is performed only when there is no shelf board 2 at the same height.

[0150] Even if there are shelves 2 at the same height, in order to allow movement of the hook portion 18 in the width direction Y using the intermediate shelf support 51, the width w1 of the intermediate support should be greater than or equal to the width w of the first shelf support 12 plus the width L2 of the claw portion 32. The width w1 of the intermediate support may be, for example, 1.5 to 2 times the width w of the first shelf support 12. It is also possible to make the width w1 of the intermediate support more than twice the width w. However, if the width w1 of the intermediate support is made more than twice the width w, the width of the intermediate shelf support 51 will become too wide, which will look bad and increase costs, thus diminishing the point of consolidating them into one support. Therefore, it is best to keep it to around twice the width w1.

[0151] Furthermore, the intermediate shelf support 51 has an opening on its rear side in the depth direction X, which includes a lip. By orienting the opening towards the rear, the opening can be made less conspicuous from the outside.

[0152] Furthermore, since the intermediate shelf posts 51 are installed in a location without a wall (side wall 4), mounting holes 12c for attaching to the wall (side wall 4) are unnecessary, and support from the floor 7 becomes necessary. The intermediate shelf posts 51 may be individual, but in this embodiment, the intermediate shelf posts 51 are connected in a frame-like structure by connecting the upper and lower ends of a pair of intermediate shelf posts 51, one at the front and one at the back in the depth direction X, with upper and lower horizontal members 52 and 53. By forming an intermediate frame, the pair of intermediate shelf posts 51 are easy to handle and easy to install on the floor 7.

[0153] The intermediate frame may be constructed from a C-shaped cross section member with a lip, similar to the intermediate shelf column 51. The upper horizontal member 52 has an open surface with a lip on its top. The lower horizontal member 53 has an open surface with a lip on its bottom. This makes the opening less conspicuous from the outside.

[0154] The intermediate shelf post 51 is formed so that its upper end is at the same height as the upper end of the first shelf post 12. A top plate 54 is attached to the upper horizontal member 52. The top plate 54 has dimensions that are approximately the same as or larger than those of the shelf board 2 in the depth direction X. The top plate 54 extends in the width direction Y, with both ends reaching the position of the upper end of the first shelf post 12, and is attached to the upper end of the first shelf post 12 directly, or to the upper wall (side wall 4) of the upper end, via L-shaped corner brackets (top plate support brackets 55) or the like using screws.

[0155] The intermediate shelf support 51 is formed to a length where its lower end reaches the floor 7. The lower horizontal member 53 is placed on the floor 7 and fixed to the floor 7 from above with screws or the like. Screw holes 53a are formed through the upper surface of the lower horizontal member 53 for passing screws through.

[0156] To summarize the above, in this embodiment of the storage shelf 1, multiple shelves 2 can be installed side by side in the width direction Y. Intermediate shelf posts 51 are installed between adjacent shelf posts 2 in the width direction Y. These intermediate shelf posts 51 have shelf mounting surfaces 12a on both sides in the width direction Y, each having a locking hole 17.

[0157] Furthermore, with the storage shelf 1 of this embodiment, compared to the case where multiple storage shelves 1 of Embodiment 1 are arranged in the width direction Y and shelves 2 are installed on each storage shelf 1, the structure can be consolidated into a single storage shelf 1. In addition, the storage shelf 1 of this embodiment has a simple structure, is aesthetically pleasing, has high storage capacity, and is suitable for large storage spaces.

[0158] Furthermore, the storage shelf 1 in this embodiment achieves cost reductions through space saving and reduced assembly time by consolidating two shelf supports 12, which are provided between adjacent shelf boards 2, into an intermediate shelf support 51. In addition, the appearance quality of the storage shelf 1 can be improved by consolidating the structure.

[0159] Other than those mentioned above, the configuration is the same as in the above embodiment, and the same effects and advantages as in the above embodiment can be obtained. [Explanation of Symbols]
