Description

[Technical field]

[0001] The present invention relates to a shelf support structure having a vertically extending support column and a shelf bracket for supporting a shelf. [Background technology]

[0002] Generally, as shown in FIG. 21, a support 101 has a plurality of mounting holes 103 arranged at a predetermined pitch in the vertical direction. On the other hand, the shelf bracket is formed with an engagement claw 104 that detachably engages with a desired one of a plurality of mounting holes 103 in the support.

[0003] 21, the conventional shelf support structure 100 is configured such that the above-mentioned multiple support posts 101 are arranged in an upright state along side walls 110a, 110b of a case equipped with a shelf 111, such as a display case or storage case, so as to be spaced apart in the width direction V and depth direction W of the internal space of the case. The above-mentioned multiple shelf brackets 102 are attached to each of the multiple support posts 110 at the same height to suspend the shelf 111 equipped in the case.

[0004] The conventional shelf support structure 100 shown in FIG. 21 has four pillars 101, of which two pillars 101a arranged on one side of the width direction V of the case are attached to a side wall portion 110a on that side, and two pillars 101b arranged on the other side are attached to a side wall portion 110b on the other side.

[0005] Generally, in order to suspend the shelf 111 by the plurality of shelf brackets 102 without rattling or prying, a so-called leveling operation is performed to mount the plurality of supports 101 at the same mounting height. In this leveling operation, for example, height measurement from the floor or ceiling and positioning operations must be performed so that there is no error of millimeters in the mounting height at which the multiple support columns 101 are attached to the side walls 110a, 110b. However, in the above-mentioned conventional shelf support structure 100, the above-mentioned leveling operation must be performed not only for the multiple support columns 101 provided in the width direction V of the case but also in the depth direction W, which is a concern as it requires a lot of work.

[0006] On the other hand, even though the shelf bracket receives a load applied downward through the shelf, if the number of posts to which the shelf bracket is attached is simply reduced for leveling work, the farther the point on the shelf bracket is from the point of attachment to the post, the more likely it is to receive a moment load based on the downward load described above, and there is a concern that the shelf may tilt inadvertently, causing it to rattle or be gouged as described above.

[0007] In contrast to this, in Patent Document 1, while a configuration is provided with one support for each side wall of a storage case etc., multiple engaging claws are provided along the vertical direction of the shelf bracket, and these engaging claws engage with multiple mounting holes in the support, thereby increasing the support strength of the shelf bracket against the support.

[0008] However, the shelf bracket of Patent Document 1 only has two engaging claws arranged along one direction (i.e., only the up-down direction), and there is room for further improvement, for example in the layout and shape of the engaging claws, in order to increase the attachment strength of the shelf bracket to the support column in response to the action of the moment load described above. [Prior art documents] [Patent documents]

[0009] [Patent Document 1] JP 2013-247990 A Summary of the Invention [Problem to be solved by the invention]

[0010] To provide a shelf support structure that can firmly support shelves without gouging them with shelf brackets attached to the supports, while reducing the number of supports from the conventional level in order to simplify shelf leveling work. [Means for solving the problem]

[0011] This invention is a shelf support structure comprising a pillar extending in the vertical direction and a shelf bracket supporting a shelf, wherein the pillar has a plurality of engageable holes arranged at predetermined intervals in each of the width and vertical directions for releasably attaching the shelf bracket, and the shelf bracket has a plurality of engaging claws arranged in each of the vertical and width directions corresponding to the locations of the engaged holes so as to be engageable with and releasable from the engaged holes, and all of the engaging claws are formed by protrusions cut and raised from the plate-shaped shelf bracket.

[0012] According to the above configuration, the engaging claw and the engaged hole can be engaged at multiple points in both the vertical and horizontal directions, so that even if a moment load acts on the shelf bracket due to the shelf bracket supporting the shelf in a cantilever manner in the width direction, the moment load can be firmly absorbed by the multiple engagement points between the engaging claw and the engaged hole. Therefore, the shelf bracket can be securely attached to the support without rattling or gouging.

[0013] Furthermore, since the multiple engaging claws are formed by cutting and raising, as described above, they can be easily formed by press molding, etc., even in a configuration in which multiple engaging claws are provided in the vertical and width directions of the shelf bracket.

[0014] As an aspect of the present invention, the engaging claw may be cut and raised in the width direction from a cut and raised base end portion extending in the up-down direction as a starting point.

[0015] When the shelf bracket is engaged with the support, loads are likely to be applied to the engaging claws in the vertical direction. However, with the above configuration, the base end of the cut and raised part, which is the starting point of the cut and raised part, extends in the vertical direction. In other words, the cut and raised direction is set in a direction (width direction) different from the vertical direction in which loads are likely to be applied. As a result, the cut and raised plate-shaped engaging claws are less likely to bend and deform inadvertently in response to the load from the shelf when they engage with the engaged hole, and can firmly withstand the load.

[0016] As an aspect of the present invention, the engaging claws may include a pair arranged in parallel in the width direction, and may be cut and raised so as to open outward like double doors relative to each other.

[0017] According to the above configuration, the pair of engaging claws can be cut and raised so as to open like a double door, in a direction that moves them away from each other in the width direction, thereby efficiently absorbing the moment load acting by supporting the shelf bracket shelf.

[0018] In one aspect of the invention, the shelf bracket comprises a shelf support portion that supports the shelf, and a pillar mounting portion having the engaging claw, the pillar mounting portion being formed to extend to at least one side in the upward or downward direction relative to the shelf support portion, and a bracket-side fastening hole that allows the insertion of a fastening member may be provided in the pillar mounting portion at a position toward the tip side in the extension direction of the engaging claw.

[0019] According to the above configuration, the shelf support portion of the shelf bracket attached to the support pillar supports the shelf, so that even if a moment load acts on the support pillar mounting portion of the shelf bracket, the moment load can be effectively absorbed by the fastening member fastened to the bracket side fastening hole from a position at the tip side in the extension direction of the support pillar mounting portion, i.e., a position spaced apart in the vertical direction from the shelf support portion.

[0020] Therefore, rattling or gouging of the shelf bracket attached to the support can be effectively suppressed.

[0021] As an aspect of the invention, the pillar mounting portion extends to either the upper or lower side relative to the shelf support portion, and the three engaging claws are arranged in at least one row along the extension direction, and the bracket side fastening hole may be provided at a position farther away than the engaging claw that is furthest away from the shelf support portion in the extension direction among the three engaging claws.

[0022] According to the above configuration, the bracket side fastening hole can be provided at a position further away from the shelf support portion than the engaging claw that is furthest away from the shelf support portion among the three engaging claws arranged in at least one row along the extension direction, thereby ensuring sufficient vertical spacing from the shelf support portion.

[0023] In this way, by fastening the fastening member in the bracket side fastening hole located at a position spaced apart from the shelf support portion, even if the shelf support portion receives a load from the shelf and a moment load acts on the shelf support portion, the moment load can be firmly received at the fastening point spaced apart from the shelf support portion to either side in the vertical direction.

[0024] Furthermore, by attaching at least three of the engaging claws arranged along the extending direction to the respective mounting holes of the support, the shelf bracket can be securely engaged with the support. As described above, rattling and gouging of the shelf bracket attached to the support can be effectively suppressed.

[0025] As an aspect of the invention, the post may have a plurality of post-side fastening holes arranged at the above-mentioned predetermined intervals in the vertical direction to allow the insertion of fastening members for fastening the shelf bracket to the post, and a notch may be formed on the periphery of the post-side fastening hole extending radially outward from the post-side fastening hole.

[0026] According to the above configuration, the post-side fastening hole can be expanded or contracted to some extent by the notch when the fastening member is inserted, so that the peripheral portion tightly adheres to the inserted fastening member and can hold the fastening member. In other words, the post-side fastening hole can firmly fasten (insert) the fastening member without additional processing such as threading.

[0027] In particular, when forming the pillar-side fastening hole, which allows the fastening member to be firmly fastened (inserted), the hole can be easily formed by punching, including the notch, without requiring additional processing such as threading.

[0028] As an aspect of the invention, the support may have a main wall portion on its front surface facing the shelf bracket, and a side wall portion protruding rearward from at least one side edge portion in the width direction of the main wall portion formed along the side edge portion, and a vertical rib may be formed along the vertical direction protruding rearward from the rear surface of the shelf bracket so as to be guided in the width direction relative to the side wall portion when the engaging claw and the engaged hole are engaged.

[0029] According to the above configuration, the vertical rib of the shelf bracket engages with the side wall portion of the support in the vertical direction, thereby effectively suppressing rattling or gouging of the shelf bracket attached to the support.

[0030] As an aspect of the invention, the side wall portions may be formed on both sides of the main wall portion in the width direction, and the vertical ribs may be arranged in pairs in the width direction of the shelf bracket at a distance corresponding to the main wall portion so that they can be guided from the outside in the width direction relative to the side wall portions on both sides in the width direction.

[0031] According to the above configuration, the shelf bracket can be attached to the support from the front by the pair of vertical ribs so as to surround (embrace) the support, thereby making it possible to suppress misalignment on both sides in the width direction. Effect of the Invention

[0032] According to the present invention, it is possible to provide a shelf support structure that can firmly support a shelf without gouging the shelf by using shelf brackets attached to posts. [Brief description of the drawings]

[Figure 21] Illustrative diagram of a conventional shelf support structure DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0034] An embodiment in which the shelf support structure of the present invention is applied to a storage case 1 with shelves will be described below. As shown in FIG. 1, the storage case 1 of this embodiment comprises a case main body 2 having an internal space 1s for storing items such as books, a plurality of shelves 3 (only one is shown) arranged horizontally in the internal space 1s, and a shelf support structure 10.

[0035] The case main body 2 includes a case underside (not shown) which corresponds to the floor of the internal space 1s, a pair of case side walls 4 (only one in the case width direction is shown) which face each other across the internal space 1s in the case width direction, and a case rear wall 5 which is located on the rear side of the internal space 1s, and is configured so that at least the front side of the case (front surface side of the case) of the internal space 1s is open.

[0036] In the figure, arrow H indicates the up-down direction, arrow V indicates the width direction of the case, and arrow W indicates the depth direction of the case. The shelf board 3 is suspended by a pair of case side walls 4 via a shelf support structure 10 so as to straddle the internal space 1s horizontally in the case width direction.

[0037] The shelf support structure 10 of this embodiment includes two sets corresponding to each of the pair of case sidewalls 4 (only one in the case width direction is shown), and is symmetrical (having the same shape in this example) with respect to a line passing in the vertical direction at the middle position in the case width direction as the axis of symmetry, and is arranged to face each other across the internal space 1s. Therefore, in the following description, the shelf support structure 10 of this embodiment will be described based on the shelf support structure 10 provided on one side in the case width direction, unless otherwise specified. Also, in the following description, the shelf support structure 10 will be described based on the posture provided on the case main body 2 as shown in FIG. 1.

[0038] In addition, in the front view of the shelf support structure 10 (viewed from the side of the internal space 1s), the front side is the front direction, the back side is the rear direction, the rear side in the case depth direction is one side in the width direction, and the near side in the case depth direction is the other side in the width direction. In other words, the width direction of the shelf support structure 10 corresponds to the case depth direction, and the front-rear direction corresponds to the case width direction. In the drawings, arrow Y indicates the front-rear direction, arrow X indicates the width direction, arrow Ya indicates the front direction, arrow Yb indicates the rear direction, arrow Xa indicates one side in the width direction, and arrow Xb indicates the other side in the width direction. In the following description, the outer side in the width direction indicates at least one side in the width direction with respect to the support post mounting portion 33 of the shelf bracket 31.

[0039] As shown in FIGS. 1 to 4, the shelf support structure 10 of this embodiment includes a support column 21 extending in the vertical direction, and a shelf bracket 31 that supports the shelf board 3.

[0040] The support pillar 21 is formed, for example, by pressing (bending, punching) a metal plate such as a steel plate into a long plate shape extending linearly upward from the underside of the case with a length slightly shorter than the vertical length of the case side wall portion 4 of the storage case 1.

[0041] The support pillar 21 includes a main wall portion 22 that extends linearly in the vertical and width directions, and a pair of side wall portions 23 that protrude rearward from both side edges in the width direction over the entire vertical length of the main wall portion 22. As a result, the support pillar 21 has a cross section orthogonal to the vertical direction over approximately the entire vertical length, which is formed into a U-shape having corners on both sides in the width direction.

[0042] The support pillar 21 stands up from the underside of the case at the middle portion in the case depth direction of one of the case side walls 4 of the storage case 1, and is positioned in such a manner that the tip portions (rear ends) of the pair of side walls 23 protruding rearward abut against one of the case side walls 4 from the side of the internal space 1s (see Figures 4(b)(d)).

[0043] 2, 3, 4(a), 4(b) and 4(c), a plurality of case side wall fastening holes 24 (only one is shown in the figures) are formed through the main wall 22 of the support 21 at predetermined intervals in the vertical direction, and the support 21 is attached to one of the case side walls 4 by fastening with a screw B1 inserted into the case side wall fastening hole 24. Note that, when the support 21 is attached to one of the case side walls 4, a space 21s extending in the vertical direction is defined between the main wall 22 of the support 21 and the one of the case side walls 4 facing the main wall 22 (see FIGS. 4(b) and 4(d)).

[0044] 2 and 4(b), a concave (countersink-shaped) seat 24a is formed around the periphery of the case sidewall fastening hole 24 on the front surface of the main wall portion 22 of the support 21, into which the head of the screw B1 can be embedded when the screw B1 is inserted and fastened. As a result, when the screw B1 is inserted into the case sidewall fastening hole 24 and fastened, the head of the screw B1 is formed to be approximately flush with the front surface of the main wall portion 22 without protruding forward, and is formed to firmly abut against the main wall portion 22 of the support 21 when the shelf bracket 31 is attached to the support 21.

[0045] Also, as shown in Figures 1 to 3 and 4(a)(b)(c)(d), the main wall portion 22 of the support 21 is formed with a plurality of engaged holes 25 that engage (attach) the shelf bracket 31 to the support 21 so that it can be engaged (detached) at a desired height, and a plurality of support-side fastening holes 26 (pilot holes) that allow the insertion of screws B3 as fastening members that fasten the shelf bracket 31 to the support 21.

[0046] These engaged holes 25 and post-side fastening holes 26 are both formed by punching out the locations corresponding to the respective holes 25, 26 when the metal plate material for the post 21 is press-worked. The multiple engaged holes 25 and the post-side fastening holes 26 are formed to penetrate each other so that they have the same shape and size as one another.

[0047] In detail, as shown in Figures 1 to 3 and 4(a), the engaged hole 25 is formed in the shape of a long hole that is longer in the up-down direction than in the width direction, and is formed to be longer in the up-down direction than the engaging claw 36 (see Figure 3) described later so that the engaging claw 36 can be inserted therethrough, and is formed wide around the middle part in the up-down direction.

[0048] However, the engaged hole 25 is formed to have a generally elliptical shape when viewed from the front, so that it gradually becomes narrower as it approaches the upper and lower ends relative to the vertical middle portion (see Figure 4(a)), and is formed to be narrower than the engaging claw 36 at least at both vertical ends.

[0049] As a result, when the engaging claw 36 is inserted into the engaged hole 25, the tip portion 362 (see Figure 4(b)) described later engages with the periphery of the engaged hole 25. In addition, as the mass of the shelf bracket 31 supporting the shelf board 3 urges the engaging claw 36 downward in the vertical direction of the engaged hole 25, the base portion 361 (see Figure 4(b)) described later is tightened from both widthwise edges of the engaged hole 25, which gradually become narrower toward the bottom, so that the engaging claw 36 firmly engages with the engaged hole 25.

[0050] The engaged holes 25 are arranged at predetermined intervals in both the width direction and the vertical direction of the main wall portion 22 of the support pillar 21 . 1 to 3, the engaged holes 25 are arranged at a predetermined interval (predetermined pitch) in the vertical direction of the main wall portion 22 of the support 21. The engaged holes 25 arranged in the vertical direction (hereinafter also referred to as "engaged hole group rows 25A") are provided in a total of two rows on each side separated by a middle portion in the width direction of the main wall portion 22 of the support 21.

[0051] Furthermore, in these two rows of engaged hole groups 25A, the engaged holes 25 are arranged in the vertical direction at the same pitch, and at each pitch the engaged holes 25 are arranged in parallel in the width direction to form pairs.

[0052] Also, as shown in FIG. 4(a), the pillar-side fastening hole 26 has a round hole portion 261 formed through in a perfect circular shape when viewed from the front, and a notch portion 262 extending linearly radially outward (downward) from a part of the circumferential direction of the periphery (seat surface) of the round hole portion 261 (in this example, the lower end periphery), and is formed through in an overall keyhole shape.

[0053] Although the post-side fastening hole 26 is a pilot hole that is not machined with a female thread, the notch 262 makes it easier to screw the screw B2 into the post-side fastening hole 26, and the periphery of the post-side fastening hole 26 can be deformed so as to fit closely to the screw B3 that has been screwed in, allowing the screw to be firmly fastened. The notch 262 described above is also formed when the metal steel plate for the post 21 is pressed, i.e., when the post-side fastening hole 26 is punched out. In other words, the post-side fastening hole 26 does not require additional processing to form a female thread, and the screw B3 can be firmly fastened.

[0054] 1 to 3, the above-mentioned pillar-side fastening holes 26 are arranged at a predetermined interval in the vertical direction at the intermediate position in the width direction of the main wall portion 22, i.e., at the position between the two rows of engaged hole groups 25A. These vertically arranged pillar-side fastening holes 26 (hereinafter also referred to as "pillar-side fastening hole groups 26A") are arranged so that each pitch is at the same height as the engaged holes 25 corresponding to each pitch of the two rows of engaged hole groups 25A.

[0055] The above-mentioned case side wall fastening hole 24 is formed at a predetermined location (predetermined height) in the vertical direction of the support 21, in a portion between two predetermined support side fastening holes 26 adjacent in the vertical direction.

[0056] Next, the shelf bracket 31 will be described. The shelf bracket 31 includes a shelf support portion 32 that supports the shelf board 3 and a post attachment portion 33 that is attached to the post 21 .

[0057] In other words, the shelf bracket 31 comprises a widthwise extending portion 41 having an L-shaped cross section that extends linearly in the width direction, and a downward extending portion 42 that extends linearly downward from the middle position in the width direction of the widthwise extending portion 41, and is formed overall into an approximately T-shape when viewed from the front by pressing a metal steel plate.

[0058] As shown in Figures 5(a), (b), and (c), the widthwise extending portion 41 comprises a horizontal piece 43 that extends horizontally and linearly so that the widthwise direction is longer than the front-to-rear direction, and a vertical piece 44 that protrudes downward from the rear end of the horizontal piece 43 over the entire widthwise length and extends linearly like a vertical wall so that the widthwise direction is longer than the top-to-bottom direction.

[0059] In addition, the widthwise extending portion 41 is formed by bending the portion corresponding to the horizontal piece 43 and the portion corresponding to the vertical piece 44 of the metal steel plate for the shelf bracket 31 at right angles to each other, so that the cross section perpendicular to the width direction between the vertical piece 44 and the horizontal piece 43 is L-shaped over the entire width direction length. The downward extension 42 extends downward in a straight line from the middle position of the vertical piece 44 in the width direction.

[0060] 1 to 6, the shelf support portion 32 is formed of a widthwise extending portion 41 extending in the width direction, excluding a widthwise central portion (a portion directly above the downward extending portion 42) of the vertical piece 44. In other words, the shelf support portion 32 is formed of the widthwise extending portion 41, excluding the entire horizontal piece 43 and the widthwise central portion of the vertical piece 44.

[0061] 1, the shelf support portion 32 is formed so as to be able to support one end of the shelf board 3 in the case width direction when placed on the upper surface of the horizontal piece 43 of the widthwise extending portion 41, and has a widthwise length that is slightly shorter than the length of the shelf board 3 in the depth direction of the case body. As shown in FIG. 2, the horizontal piece 43 has a plurality of screw holes 43a formed therethrough at a widthwise intermediate position and at positions spaced a predetermined distance on both sides of the widthwise intermediate position for fastening the shelf board 3 placed on the horizontal piece 43 with screws B2.

[0062] 1 to 3 and 6(a) and (c), horizontal ribs 45 protruding rearward are formed on both sides of the shelf support portion 32 in the width direction separated by the downward extension portion 42 of the vertical piece 44. These horizontal ribs 45 are formed linearly along the lower edge of the vertical piece 44 from the corner portion 7 between the vertical piece 44 and the downward extension portion 42 to the outside in the width direction. In this embodiment, the horizontal rib 45 is formed to the middle of the vertical piece 44 extending from the downward extension portion 42 to both outer sides in the width direction, but it may also be formed, for example, to the outer width ends of the vertical piece 44 extending to both outer sides in the width direction.

[0063] On the other hand, the above-mentioned pillar attachment portion 33 is constituted by the widthwise central portion of the vertical piece 44 (the portion directly above the downward extension portion 42) in the widthwise extending portion 41, and the downward extension portion 42, as described above.

[0064] The pillar mounting portion 33 includes a main wall portion 34 and a pair of vertical ribs 35 . The main wall portion 34 of the pillar mounting portion 33 is formed in a generally flat plate shape extending linearly in the vertical and width directions so as to be able to abut against the main wall portion 34 of the pillar 21 from the front side, and is formed slightly wider than the main wall portion 22 of the pillar 21.

[0065] The main wall portion 34 of the pillar mounting portion 33 is provided with a plurality of engaging claws 36 (six in this example) that can be detachably engaged with the engaged hole 25 of the pillar 21, and one bracket side fastening hole 37 that allows the insertion of a screw B3 as a fastening member for fastening the shelf bracket 31 to the pillar 21.

[0066] As shown in Figures 4(b) and (d), each of the multiple engaging claws 36 is formed by a protrusion that is cut and raised from the main wall portion 34 of the plate-shaped pillar mounting portion 33 rearward and outward in the width direction, starting from a cut-and-raised base end portion 36a extending in the vertical direction.

[0067] As shown in FIG. 4(b), the engaging claw 36 has a base portion 361 that protrudes rearward from the cut-and-raised base end portion 36a, and a tip portion 362 that protrudes further rearward than the base portion 361. A base 361 of the engaging claw 36 protrudes slightly longer than the thickness of the main wall portion 22 of the support 21. A tip portion 362 of the engaging claw 36 protrudes downward beyond the lower end of the base 361 so as to be able to engage with the edge of the engaged hole 25 when inserted through the engaged hole 25. As shown in Figures 4(b) and (d) , the tip portion 362 of the engaging claw 36 is disposed in the space 21s between the main wall portion 34 of the support 21 and one of the case side walls 4 when the engaging claw 36 is engaged with the engaged hole 25 of the support 21.

[0068] As shown in Figures 4(a), 4(b), 4(c) and 5(b), an opening 38 is formed through the main wall 34 of the post mounting portion 33 on the inside (center) of the width direction relative to the engaging claw 36. This opening 38 is formed when the metal steel plate for the shelf bracket 31 is pressed, by punching out the peripheral portion of the metal steel plate except for the cut-and-raised base end 36a of the portion corresponding to the engaging claw 36 before cutting and raising the portion corresponding to the engaging claw 36 from the cut-and-raised base end 36a as a starting point. As shown in Figures 4(a), 4(b), 4(d) and 5(b), the cut-and-raised base end 36a is formed in the vertical direction along the outer edge 38a of the opening 38.

[0069] As shown in FIG. 2, a plurality of the above-mentioned engaging claws 36 are arranged in the vertical and width directions of the main wall portion 34 of the pole attachment portion 33 in correspondence with the locations of the above-mentioned engaged holes 25 .

[0070] 6(a), 6(b), and 6(c), the engaging claws 36 are disposed at predetermined intervals (predetermined pitch) in the up-down direction of the main wall portion 34 of the pole mounting portion 33. These multiple (three in this example) engaging claws 36 (hereinafter also referred to as "engaging claw group row 36A") (see FIG. 6(c)) disposed in the up-down direction are provided in a total of two rows (six in this example) on each side separated by a middle portion in the width direction of the main wall portion 34 of the pole mounting portion 33.

[0071] In these two rows of engaging claw groups 36A, the engaging claws 36 are vertically arranged at the same pitch, and at each pitch the engaging claws 36 are arranged in parallel in the width direction so as to form pairs.

[0072] As described above, the engaging claws 36 are cut and raised in the shape of protrusions extending rearward and outward in the width direction from the main wall portion 34 of the plate-shaped pillar mounting portion 33. Therefore, when arranged in parallel in the width direction, the engaging claws 36 are cut and raised in directions that move away from each other in the width direction, i.e., like a double door.

[0073] The bracket side fastening hole 37 is formed as a round hole formed through the bracket side fastening hole 37 in a perfect circular shape when viewed from the front. The periphery of the bracket side fastening hole 37 is bent so that the entire periphery is raised forward, and the front surface of the raised portion is formed with a flat seat surface 37a. As shown in Fig. 4(b), the center of the seat surface 37a, i.e., the periphery of the bracket side fastening hole 37, is formed in a concave shape (countersink shape) so that the head of the screw B3 can be embedded when the screw is inserted and fastened.

[0074] In this embodiment, the screw B3 is a countersunk head tapping screw with a flat head tip, while the seat surface 37a around the periphery of the bracket side fastening hole 37 is formed into a cone-like recess to accommodate the head of the countersunk head tapping screw B3. As a result, when the screw B3 is inserted into the bracket side fastening hole 37 and fastened, the head of the screw B3 is formed to be substantially flush with the front surface of the seat surface 37a without protruding forward.

[0075] Here, as shown in Figures 4(a)(c), 5(b) and 6(c), in an embodiment, the widthwise central portion of the vertical piece 44 in the pillar mounting portion 33 has a vertical length equivalent to one vertical arrangement pitch of the engagement claws 36.

[0076] On the other hand, the downward extension portion 42 of the post mounting portion 33 has a length equivalent to three vertical arrangement pitches of the engagement claws 36 and extends downward beyond the shelf support portion 32. As a result, the post mounting portion 33 as a whole has a vertical length equivalent to four vertical arrangement pitches of the engagement claws 36.

[0077] As shown in FIGS. 6(b) and 6(c), a pair of engagement claws 36u located at the uppermost row (first pitch from the top) of the two engagement claw rows 36A is provided at the center portion of the vertical piece 44 in the width direction.

[0078] Furthermore, a pair of engagement claws 36m located in the vertical middle (middle row) (second pitch from the top) of the two engagement claw rows 36A are provided on the upper part of the downward extension portion 42, a pair of engagement claws 36d located in the lowest row (third pitch from the top) are provided at the vertical middle position of the downward extension portion 42, and the bracket side fastening hole 37 is provided in the lower part of the downward extension portion 42 (fourth pitch from the top).

[0079] In this way, the multiple engaging claws 36 are arranged at locations equivalent to three pitches from the top on the main wall portion 34 of the pillar mounting portion 33, and the bracket side fastening hole 37 is provided at the fourth pitch from the top so as to be further downward than the lower engaging claw 36d, which is the furthest downward from the horizontal piece 43 supporting the shelf board 3.

[0080] As shown in Figs. 1 to 3, 4(b), 4(c), 4(d), and 6(a), 6(b), 6(c), the support post attachment portion 33 includes a main wall portion 34 and a pair of vertical ribs 35. The vertical ribs 35 protrude rearward from both side edges of the main wall portion 34 in the width direction in the downward extension portion 42 of the support post attachment portion 33. The pair of vertical ribs 35 are formed so that the protruding length rearward is slightly shorter than the protruding length of the corresponding side wall portion 23 in the width direction of the support post 21 (see Fig. 4(d)). The pair of vertical ribs 35 are formed over the entire vertical length of the downward extension portion 42. As a result, the downward extension portion 42 is formed by the main wall portion 34 and the pair of vertical ribs 35 into a U-shape (C-shape) having corners on both sides in the width direction in a cross section perpendicular to the vertical direction over approximately the entire vertical length.

[0081] 4(d), when the main wall portion 34 is in contact with the main wall portion 22 of the pillar 21 from the front side, the pair of vertical ribs 35 of the pillar mounting portion 33 described above contact the corresponding side wall portions 23 of the pillar 21 from the outside in the width direction, thereby guiding them in the width direction. That is, the downward extension portion 42 of the pillar mounting portion 33 is disposed so as to be fitted into the pillar 21 from the front (embracing it from both sides in the width direction).

[0082] As shown in Figures 4(c) and 6(c), on both sides of the width of the shelf bracket 31, the vertical ribs 35 and the horizontal ribs 45 are integrally formed at the corner portions 7 between the widthwise extending portion 41 (shelf support portion 32) and the downward extending portion 42 (pillar mounting portion 33).

[0083] More specifically, on both sides of the shelf bracket 31 in the width direction, the corner portion 7 between the widthwise extending portion 41 (shelf support portion 32) and the downward extending portion 42 (pillar mounting portion 33) is formed in an arc shape that gently connects the lower edge of the vertical piece 44 of the widthwise extending portion 41 extending in the width direction to the side edge of the downward extending portion 42 extending in the up-down direction in a front view. The vertical rib 35 and the horizontal rib 45 are continuous in an arc shape along the edge of the corner portion 7. The vertical rib 35 and the horizontal rib 45 are formed to protrude rearward with the same protruding length.

[0084] As shown in Figures 1 to 3, the shelf support structure 10 of the present embodiment described above comprises a pillar 21 extending in the vertical direction and a shelf bracket 31 supporting a shelf board 3, and the pillar 21 has a plurality of engageable holes 25 arranged at predetermined intervals in each of the width direction and the vertical direction for releasably attaching the shelf bracket 31, and the shelf bracket 31 has a plurality of engaging claws 36 arranged in correspondence with the locations of the engaged holes 25 so that the engaging claws 36 can engage with the engaged holes 25 at multiple points in each of the vertical direction and the width direction.

[0085] As a result, the shelf board 3 is supported via the shelf bracket 31 by the pillars 21 provided on each of a pair of opposing case side wall portions 4 (only one of the width directions is shown) in the case width direction, and the shelf support portion 32 receives the load from the shelf board 3 in a cantilever manner in the width direction, so that even if a moment load acts on the shelf support portion 32, the moment load can be firmly received. Therefore, the number of supports 21 can be reduced, reducing the time and effort required for leveling between the multiple supports 21, while the shelf brackets 31 can be securely attached to the supports 21 without rattling or being gouged out.

[0086] Furthermore, since the multiple engaging claws 36 are all formed by protrusions cut and raised from the plate-shaped shelf bracket 31, they can be easily and accurately formed by press molding, etc., even in a configuration in which multiple engaging claws are provided on the shelf bracket 31 in the vertical and horizontal directions.

[0087] That is, for example, if multiple engagement claws 36 are formed individually, there is a risk of variation in precision between the multiple engagement claws 36, but by forming them by molding as in this embodiment, such variation can be mitigated.

[0088] Furthermore, for example, in a configuration in which a plate on which multiple engaging claws 36 are already arranged is later attached to the shelf bracket 31 by welding or the like, there is a risk that the attachment position and posture of the multiple engaging claws 36 will shift depending on the attachment accuracy of the plate to the shelf bracket 31. However, by forming them by molding as in this embodiment, it is possible to reduce the positional shift of the multiple engaging claws 36 provided on the main wall portion 34.

[0089] Furthermore, as shown in FIG. 7, the shelf support structure 10 of this embodiment is applied to a storage case 1 installed in a closet or the like, and even in an indoor space where there is a hanging wall 50 hanging down from the ceiling on the front side in the depth direction and the top shelf board 3 is placed in the space 50s behind the hanging wall 50, items can be easily placed on and off the shelf board 3 without being hindered by the hanging wall 50.

[0090] In detail, as described above, the shelf support structure 10 of this embodiment can engage the engaging claws 36 and the engaged holes 25 at multiple points in the vertical and width directions, so that the pair of case side walls 4 are each provided with one support 21, and the shelf brackets 31 extending in the width direction support the shelf board 3, so that the shelf brackets 31 can firmly receive the moment load even if the moment load acts on the shelf brackets 31 due to the shelf board 3 being supported via the shelf brackets 31 extending in the width direction. Therefore, as shown in FIG. 7, the shelf board 3A with a shallow depth can be firmly supported even when the shelf board 3A is shifted toward the rear side in the case depth direction from the position of the support 21. By shifting the shelf board 3A with a shallow depth toward the rear side in this way, even when the shelf board 3 is placed in the space 50s behind the hanging wall 50, the space 50s can be secured between the hanging wall 50 and the shelf board 3, so that items can be easily placed on and off the shelf board 3 through the space 50s.

[0091] As an aspect of the present invention, as shown in FIG. 5(b), the engaging claw 36 is cut and raised starting from the vertically extending cut-and-raised base end 36a, so that the cutting and raising direction can be set in a direction different from the vertical direction in which load is likely to be applied (rearward and outward in the width direction), and the engaging claw 36 can be firmly engaged with the engaged hole 25.

[0092] Specifically, when the shelf bracket 31 is engaged with the support 21, a load is likely to be applied to the engaging claw 36 in the vertical direction. In contrast, in this embodiment, the direction in which the engaging claw 36 is cut and raised (the direction in which it is bent and deformed) starting from the cut-and-raised base end 36a is set to a direction different from the vertical direction in which a load is likely to be applied to the engaging claw 36 by supporting the shelf board 3, so that the plate-shaped engaging claw 36 cut and raised in a cantilever shape is less likely to bend and deform inadvertently due to the load from the shelf board 3 when engaged with the engaged hole 25, and the load can be firmly received.

[0093] In one embodiment of the invention, as shown in Figures 3, 4(c)(d), and 6(c), a pair of engaging claws 36 are provided in parallel in the width direction, and can be cut and raised so that they open like a double door, so that they are cut and raised in directions that are as far apart as possible in the width direction.This pair of engaging claws 36 can efficiently absorb the moment load that acts as a result of supporting the load from the shelf 3 in a cantilever manner in the width direction.

[0094] In one embodiment of the invention, as shown in Figures 2, 3, 4(c), 5(b) and 6(c), the shelf bracket 31 comprises a shelf support portion 32 that supports the shelf board 3, and a pillar mounting portion 33 provided with an engaging claw 36, the pillar mounting portion 33 being formed to extend downwardly from the shelf support portion 32, and a bracket side fastening hole 37 is provided at a lower portion of the pillar mounting portion 33 that is located toward the tip side in the extension direction relative to the engaging claw 36, to allow the insertion of a screw B3 as a fastening member for fastening the shelf bracket 31 to the pillar 21.

[0095] According to the above configuration, even if a moment load acts on the shelf bracket 31 attached to the pillar 21 due to the shelf support part 32 supporting the load from the shelf board 3 in a cantilever manner in the width direction, the moment load can be effectively received by the screw B3 from a position at the tip side of the extension direction of the pillar mounting part 33, i.e., a position as far away as possible downward from the shelf support part 32. Therefore, rattling or gouging of the shelf bracket 31 attached to the support 21 can be effectively prevented.

[0096] In one embodiment of the invention, as shown in the figure, the post mounting portion 33 extends downward relative to the shelf support portion 32 and has two rows of three engaging claws 36 arranged along the downward extension direction, and the bracket side fastening hole 37 is located further below the lowest engaging claw 36d (see Figure 6(a)) of the six engaging claws 36, thereby ensuring sufficient vertical spacing relative to the shelf support portion 32.

[0097] This allows the shelf bracket 31 to be firmly attached to the support column even if a moment load acts on the shelf support portion 32 due to the shelf support portion 32 supporting the load from the shelf board 3 in a cantilever manner in the width direction.

[0098] Furthermore, by engaging the six engaging claws 36 arranged in the vertical and width directions with the respective engaged holes 25 of the support 21, the shelf bracket 31 can be securely attached to the support 21. As described above, rattling and gouging of the shelf bracket 31 attached to the support 21 can be effectively suppressed.

[0099] In one embodiment of the present invention, as shown in Figures 1 to 3 and 4(a), a plurality of post-side fastening holes 26 are arranged at predetermined intervals in the vertical direction on the post 21 to allow insertion of screws B3 as fastening members for fastening the shelf bracket 31 to the post 21, and as shown in Figure 4(a), a notch 262 is formed on the periphery of the post-side fastening hole 26, extending downward (radially outward) from the round hole portion 261 of the post-side fastening hole 26.

[0100] According to the above configuration, the post-side fastening hole 26 can expand or contract to some extent as the screw B3 is inserted because of the notch 262. Therefore, the peripheral edge of the post-side fastening hole 26 can be tightly attached to the inserted screw B3, and the fastened state can be firmly maintained.

[0101] Therefore, the post-side fastening hole 26 can firmly fasten (insert) the screw B3, and the screw B3 can be firmly fastened without performing additional processing such as thread cutting. That is, the post-side fastening hole 26 can be easily formed, including the notch 262, for example, when punching out the post-side fastening hole 26 in the press forming process of the metal steel plate for the post 21.

[0102] In one embodiment of the invention, as shown in Figures 1 to 3 and 4(a) to (d), the pillar 21 has a main wall portion 22 facing the pillar mounting portion 33 on its front side, and a pair of side wall portions 23 protruding rearward from both side edges of the main wall portion 34 in the width direction, and the shelf support portion 32 has vertical ribs 35 formed along the vertical direction which protrude rearward so as to guide the side wall portions 23 in the width direction when the engaging claws 36 are engaged with the engaged holes 25, and a pair of the vertical ribs 35 are arranged at intervals in the width direction of the pillar mounting portion 33 so as to be able to guide each of the pair of side wall portions 23 from the outside in the width direction.

[0103] According to the above configuration, the shelf bracket 31 can be attached to the support pillar 21 from the front by embracing it from both sides in the width direction with a pair of vertical ribs 35, i.e., by fitting the support pillar 21 in the width direction. Even if a moment load acts on the shelf support portion 32 due to the shelf support portion 32 supporting the load from the shelf board 3 in a cantilever manner in the width direction, rattling or gouging of the shelf bracket 31 attached to the support pillar 21 can be suppressed.

[0104] 1 to 3, 4(b)(c), 5(a), and 6(a)(c), in an embodiment of the present invention, horizontal ribs 45 extending along the width direction are formed on shelf support portion 32, thereby increasing the strength of shelf support portion 32. Furthermore, horizontal ribs 45 extending in the width direction and vertical ribs 35 extending in the up-down direction extend continuously with each other along arc-shaped corner portions 7 between shelf support portion 32 and post attachment portion 33 (see FIG. 6(c)), thereby enabling shelf support portion 32 and post attachment portion 33 to mutually increase their strength.

[0105] In detail, when the pillar mounting portion 33 is attached to the pillar 21, when the side wall portion 23 of the pillar 21 is guided in the width direction by the vertical rib 35, the load acting on the vertical rib 35 can be transmitted and distributed to the horizontal rib 45, while when the shelf board 3 is supported by the shelf support portion 32, the load acting on the horizontal rib 45 can be transmitted and distributed to the vertical rib 35.

[0106] Next, a description will be given of shelf support structures 10', 10A, 10A', 10B, 10B', 10C, 10C', 10D, 10D', 10E, 10E', 10F, 10F', 10G, and 10G' that are modifications of the shelf support structure 10 of the above-described embodiment. However, the same components as those of the above-described embodiment will be given the same reference numerals and the description thereof will be omitted.

[0107] (Variation 1) As shown in FIG. 8, the support pillar 21 provided in the shelf support structure 10' of the first modified example is disposed on one side in the width direction (the back side in the case depth direction) rather than at the center position in the width direction (the case depth direction).

[0108] On the other hand, shelf bracket 31' provided in shelf support structure 10' of modified example 1 is formed so that shelf support portion 32 does not extend to either outer side in the width direction relative to post mounting portion 33, but extends only to the other side in the width direction (the front side in the depth direction of the case) as shown in Figures 8, 9(a), (b), (c), and 10(c). Note that shelf bracket 31' has a length slightly shorter than the length of shelf board 3 in the depth direction of the case.

[0109] Furthermore, as shown in Figures 9(b) and 10(a)(b)(c), one of the widthwise side edges of the post mounting portion 33 has an upper end that extends in a straight line in the vertical direction to the vicinity of the horizontal piece 43 of the shelf support portion 32, and accordingly, one of the widthwise vertical ribs 35 extends in a straight line upward not only to the downward extension portion 42 but also to the vicinity of the upper end of the post mounting portion 33, as shown in Figures 10(a)(c). According to the above configuration, the single support pillar 21 for attaching the shelf bracket 31' supporting the shelf board 3 is configured to be moved all the way to one end in the depth direction of the case, making it difficult to see the support pillar 21 from the near side in the depth direction of the case, i.e., from the front side of the storage case 1, thereby improving the external design of the storage case 1.

[0110] Furthermore, even if a large moment load acts on the shelf support portion 32 due to the pillar mounting portion 33 of the shelf bracket 31' being positioned toward the rear side in the case depth direction, the moment load can be firmly received by the shelf support portion 32.

[0111] In detail, by moving the pillar mounting portion 33 of the shelf bracket 31' toward the rear in the depth direction of the case, the extension length of the shelf support portion 32 to one side in the width direction is increased, making it easier for a larger moment load to act on the shelf support portion 32.

[0112] In contrast, in this embodiment, when attaching the shelf bracket 31' to the support 21, the engaging claws 36 and the engaged holes 25 can be engaged at multiple points in both the vertical and horizontal directions, so that even if the moment load described above is applied, the moment load can be firmly absorbed.

[0113] (Variation 2-1) As shown in Figures 11(a)(b)(c)(d)(e), the shelf bracket 31A provided in the shelf support structure 10A of modified example 2-1 does not have vertical ribs 35 or horizontal ribs 45, and the vertical piece 44A extends over the entire width direction to the lower end of the downward extension portion 42, and is formed into a vertical wall that is flush and continuous with the downward extension portion 42 in the width direction and up and down directions.

[0114] According to the above configuration, by forming the vertical piece 44A into a wide vertical wall that is continuous with the downward extension portion 42 in the width direction, the support effect between the horizontal piece 43 supporting the shelf board 3 and the pillar mounting portion 33 in the shelf bracket 31A can be enhanced.

[0115] (Variation 2-2) 12(a), 12(b), 12(c), 12(d), 12(e), and 12(f), shelf bracket 31A' provided in shelf support structure 10A' of modified example 2-2 is formed, compared to shelf bracket 31A of modified example 2-1 described above, such that shelf support portion 32 extends only to the other widthwise side relative to post mounting portion 33. Also, similar to modified example 1, one widthwise side edge of post mounting portion 33 has an upper end that extends linearly in the vertical direction up to the vicinity of horizontal piece 43 of shelf support portion 32, and accordingly vertical rib 35 formed on one side in the widthwise direction extends linearly upward not only to downward extension portion 42 but also to the vicinity of the upper end. According to the above-mentioned configuration, it is possible to form the shelf 3 in a compact manner so as to be able to support the shelf 3 which is shallow in the depth direction as shown in FIG.

[0116] In the configuration of this invention and the above-mentioned embodiment, the shelf corresponds to the shelf board 3, The fastening material corresponds to screw B3. Of the three engagement claws 36, the engagement claw that is furthest away from the shelf support portion 32 in the extension direction corresponds to the lower engagement claw 36u, "To either the top or bottom side relative to the shelf support portion" corresponds to "to the bottom side relative to the shelf support portion 32," however, this invention is not limited to the configuration of the above-described embodiment, and many embodiments can be obtained.

[0117] In addition, the shelf bracket of the present invention may be formed in a notched shape such that the lower edges of vertical pieces 44B, 44C are positioned higher and further outward in the width direction than vertical piece 44A (see Figure 11) of shelf bracket 31A of modified example 2-1, such as shelf bracket 31B provided on shelf support structure 10B of modified example 3-1 shown in Figures 13(a) and (b) and shelf bracket 31C provided on shelf support structure 10C of modified example 4-1 shown in Figures 14(a), (b), (c), and (d).

[0118] In addition, in the shelf bracket 31B of the modified example 3-1, as shown in Fig. 13(a)(b), the lower edge of the vertical piece 44B is formed in a shape in which the degree of the upward cutout increases toward the outside in the width direction. In contrast, in the shelf bracket 31C of the modified example 4-1, as shown in Fig. 14(a)(c), the lower edge of the vertical piece 44C is formed in a shape in which the degree of the upward cutout decreases toward the outside in the width direction.

[0119] In addition, the shelf bracket of the present invention may have openings 60D, 60E, 60F formed through vertical pieces 44D, 44E, 44F, for example, as in shelf bracket 31D provided on shelf support structure 10D of modified example 5-1 shown in Figures 16(a)(b), shelf bracket 31E provided on shelf support structure 10E of modified example 6-1 shown in Figures 17(a)(b), and shelf bracket 31F provided on shelf support structure 10F of modified example 7-1 shown in Figures 18(a)(b).

[0120] In addition, the shelf bracket 31D of variant 5-1 has a large opening 60D formed through the center of both widthwise outer portions of the vertical piece 44D, the shelf bracket 31E of variant 6-1 has three medium openings 60E smaller than the large opening 60D arranged along the width direction in the center of both widthwise outer portions of the vertical piece 44E, and the shelf bracket 31F of variant 7-1 has a large number of small openings 60F smaller than the medium openings 60E arranged throughout both widthwise outer portions of the vertical piece 44F.

[0121] Furthermore, the shelf bracket of the present invention has been formed as, for example, shelf bracket 31A' (see FIG. 12) of modified example 2-2 as a configuration associated with shelf bracket 31A (see FIG. 11) of modified example 2-1. However, the present invention is not limited to this. As configurations associated with shelf brackets 31B, 31C, 31D, 31E, and 31F, shelf bracket 31B' provided on shelf support structure 10B' of modified example 3-2 shown in FIGS. 13(c) and (d), shelf bracket 4-2 of modified example 4-2 shown in FIGS. 15(a)(b)(c)(d) may also be used.
