Description

[Technical Field]

[0001] The present invention relates to a storage shelf. [Background technology]

[0002] A known tension pole, for example, has a pole body that can be adjusted to extend or retract, a contact part that is fitted to the upper end of the pole body so that it can slide in the axial direction of the pole, and a compression spring that is interposed between the upper end and the contact part. With this tension pole, the pole body is adjusted to extend and press the contact part against the ceiling, compressing the compression spring and bringing the lower end of the pole body into contact with the floor. Thus, the pole body is held in a tensioned state between the floor and ceiling (see, for example, Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2000-9115 Summary of the Invention [Problem to be solved by the invention]

[0004] One possible solution is to use a tension pole as the vertical frame of a storage shelf. In this case, it is preferable to make the vertical frame of the storage shelf thin to give it a slim impression, for example, from the standpoint of design. However, if the vertical frame is made thin, it is difficult to ensure the necessary size of the contact portion and compression spring. This makes it difficult to press the contact portion against the upper fixed portion (e.g., ceiling) to compress the compression spring and to abut the lower end of the pole body against the lower fixed portion (e.g., floor) to maintain the vertical frame in a tensioned state between the floor and ceiling.

[0005] To provide a storage shelf which can give a slim impression by forming a vertical frame thin, and furthermore can reliably hold the vertical frame in a stretched state between a lower fixing part and an upper fixing part. [Means for solving the problem]

[0006] In order to solve the above problems, the present invention proposes the following means. (1) The storage shelf of the present invention comprises at least four vertical frames that can be held in a tensioned state between lower and upper fixed parts, and shelves supported by the vertical frames, or shelves supported by the vertical frames via shelf support brackets, wherein the vertical frames are hollow and comprise a vertical frame body that extends in the up-down direction with one end abutting one of the lower and upper fixed parts, a support post that is inserted into the other end of the vertical frame body so as to be slidable in the axial direction and has an H-shaped cross section, a cylindrical portion that is fitted into the tip of the support post that protrudes from the vertical frame body, a contact portion that is inserted into the cylindrical portion so as to be slidable in the axial direction and can abut the other of the lower and upper fixed parts, and a compression spring that is interposed between the contact portion and the cylindrical portion.

[0007] According to the above configuration, the support pillar that is slidably inserted into the other end of the vertical frame body is formed with an H-shaped cross section. By forming the support pillar with an H-shaped cross section, the strength of the support pillar can be ensured and the cross-sectional shape of the support pillar can be kept small. This allows the vertical frame body (i.e., the vertical frame) to be formed thin, giving the impression of a slim design.

[0008] In addition, the cylindrical portion is fitted into the tip of the support post. This allows the cross section of the cylindrical portion to be made large. This allows the cross section of the contact portion that is slidably inserted into the cylindrical portion to be formed large, thereby ensuring a large contact area of ​​the contact portion that abuts against the other of the lower fixed portion and the upper fixed portion. Furthermore, the shape of the compression spring can be ensured to be of the required size. Therefore, the vertical frame can be reliably held in a tensioned state between the lower fixed portion and the upper fixed portion.

[0009] Furthermore, the contact portion is slidably inserted into the cylindrical portion. Therefore, by abutting the contact portion against the other of the lower fixed portion and the upper fixed portion, the contact portion can be pushed (entered) into the cylindrical portion and hidden. The state in which the contact portion is pushed into the cylindrical portion can be easily confirmed visually. This allows visual confirmation that the contact portion is securely abutting against the other of the lower fixing portion and the upper fixing portion, and the tensioned state of the vertical frame body can be easily confirmed at a glance.

[0010] (2) In the above aspect, the tubular portion may have an attachment portion that is attached to the tip portion of the support when fitted into the tip portion, an expansion portion that expands at an incline with respect to the axial direction as it extends from the tip of the attachment portion toward the axial direction, and a receiving portion that is provided on the expansion portion and slidably receives the contact portion.

[0011] According to this configuration, the cylindrical portion has an enlarged portion that expands at an angle, thereby ensuring a large cross-sectional shape for the receiving portion. Therefore, the cross-section of the contact portion that is slidably inserted into the receiving portion can be made large, ensuring a large contact area for the contact portion that abuts against the other of the lower fixed portion and the upper fixed portion. This allows the vertical frame to be made thin, giving it a slim impression, and furthermore, the vertical frame can be reliably held in a tensioned state between the lower fixed portion and the upper fixed portion.

[0012] (3) In the above aspect, the shelf support bracket may be attached to mounting holes formed in the left and right walls of the vertical frame body, and the support may have a pair of flanges and a web connecting the central portions of the pair of flanges, and the web may be positioned so as to face the left and right walls of the vertical frame body at a distance.

[0013] According to this configuration, in the vertical frame, a mounting hole is formed in the left wall of the vertical frame body, and a mounting hole is formed in the right wall of the vertical frame body. Furthermore, a shelf support bracket is attached to the mounting holes. Furthermore, the web of the support column is positioned with a gap between it and the left and right walls of the vertical frame body. Therefore, when the locking portion of the shelf support bracket is inserted into the mounting hole at the insertion portion of the vertical frame body where the support column is inserted, the locking portion can be prevented from interfering with the web (i.e., the support column). This allows the shelf support bracket to be attached to the insertion portion of the vertical frame body by engaging the locking portion of the shelf support bracket with the mounting hole at the insertion portion of the vertical frame body.

[0014] Next, we will explain an example of attaching shelf support brackets to the mounting holes on both the left and right walls of the vertical frame body. Hereinafter, the shelf support bracket attached to the mounting hole on the right wall of the vertical frame body will be referred to as the "first shelf support bracket," and the shelf support bracket attached to the mounting hole on the left wall of the vertical frame body will be referred to as the "second shelf support bracket." Additionally, the portion where the first shelf support bracket is attached to the mounting hole will be referred to as the "first locking portion," and the portion where the second shelf support bracket is attached to the mounting hole will be referred to as the "second locking portion."

[0015] Here, a space is secured between the left and right walls of the vertical frame body. Therefore, when the first and second locking portions are formed in the same shape, the space formed between the left and right walls can prevent interference between the first and second locking portions. As a result, when the first and second locking portions are formed in the same shape, the first shelf support bracket and the second shelf support bracket can be attached at the same height on the vertical frame body.

[0016] Furthermore, the web of the support pillar is positioned with a gap between it and the left and right walls of the vertical frame body, which prevents the first locking portion engaged with the mounting hole in the right wall and the second locking portion engaged with the mounting hole in the left wall from interfering with the web (i.e., the support pillar) at the insertion portion of the vertical frame body where the support pillar is inserted.

[0017] This prevents the first locking portion of the first shelf support bracket from interfering with the web (i.e., the support) when inserting the first locking portion into the mounting hole at the insertion portion of the vertical frame main body where the support is inserted. Also, when inserting the second locking portion of the second shelf support bracket into the mounting hole at the insertion portion of the vertical frame main body, it prevents the second locking portion from interfering with the web (i.e., the support). Therefore, even at the insertion site of the vertical frame main body, with the first locking portion and the second locking portion formed in the same shape, the first shelf support bracket and the second shelf support bracket can be attached at the same height position on the vertical frame main body.

[0018] (4) In the above aspect, the vertical frame body may include a first frame body that forms the one end side of the vertical frame and has a first connecting portion that protrudes in the axial direction from the end opposite the one end side, and a second frame body that forms the other end side of the vertical frame and has a second connecting portion that is connected to the first connecting portion by being fitted into the first connecting portion.

[0019] According to this configuration, by connecting the first connecting portion of the first frame body and the second connecting portion of the second frame body, the first frame body and the second frame body can form a vertical frame body. In other words, the vertical frame body can be divided into the first frame body and the second frame body. This allows the storage shelf to be made small and compact when transporting, for example, making it easier to transport. Furthermore, when disassembling and storing the storage shelf, the storage shelf can be made small and compact when disassembling and storing it, for example, making it easier to store.

[0020] (5) In the above aspect, the first connecting portion may have guide holes formed at positions facing the mounting holes arranged in the left side wall and the right side wall of the second connecting portion.

[0021] According to this configuration, a guide hole is formed in the first connecting portion, and the guide hole is positioned opposite the mounting hole of the second connecting portion. Therefore, when engaging the locking portion of the shelf support bracket with the mounting hole, the locking portion can be inserted into the mounting hole and the guide hole at the same time. As a result, when the second connecting portion is connected to the first connecting portion, the locking portion of the shelf support bracket 21 can be engaged with the mounting hole of the second connecting portion. Therefore, the shelf support bracket can be attached to the second connecting portion.

[0022] Next, we will explain an example of attaching shelf support brackets to the mounting holes on both the left and right side walls of the vertical frame body. The vertical frame body has guide holes formed in the first connecting section, and the guide holes are positioned opposite the mounting holes in the second connecting section. Therefore, when the first locking section of the first shelf support bracket is locked into the mounting hole, the first locking section can pass through the guide hole. This allows the first locking section of the first shelf support bracket to be locked into the mounting hole of the second connecting section when the second connecting section is connected to the first connecting section.

[0023] Similarly, when the second locking portion of the second shelf support bracket is locked into the mounting hole, the second locking portion can be passed through the guide hole. This allows the second locking portion of the second shelf support bracket to be locked into the mounting hole of the second connecting portion when the second connecting portion is connected to the first connecting portion. Therefore, even at the connection portion where the second connecting portion is connected to the first connecting portion, the first shelf support bracket and the second shelf support bracket, whose first and second locking portions are formed in the same shape, can be attached at the same height position. [Effects of the Invention]

[0024] According to the present invention, a storage shelf can be provided in which the vertical frame can be formed thin to give a slim impression, and further, the vertical frame can be securely held in a tensioned state between the lower fixing part and the upper fixing part.

[0026] Hereinafter, a storage shelf according to an embodiment of the present invention will be described with reference to the drawings. In the following explanation, unless otherwise specified, front, back, up, down, left and right refer to the front, back, up, down, left and right when looking at the storage shelf from the front. Also, the drawings show an arrow UP pointing upward on the storage shelf, an arrow FR pointing forward on the storage shelf, and an arrow LH pointing to the left side of the storage shelf. Furthermore, the axial direction of the vertical frame of the storage shelf is sometimes simply referred to as the axial direction.

[0027] First Embodiment <Storage shelf> Fig. 1 is a perspective view showing a storage shelf of the first embodiment, and Fig. 2 is a perspective view showing the configuration of the left side of the storage shelf of the first embodiment. As shown in Figures 1 and 2, the storage shelf 10 can be held by, for example, a floor section (lower fixed section) FL and a ceiling section (upper fixed section) CE in a room with four vertical frames 11, 12, 13, and 14 stretched between the floor section FL and the ceiling section CE. Therefore, the storage shelf 10 can be installed, for example, along a wall surface in a room or in any location away from the wall surface in a room. In the storage shelf 10, multiple shelves 22 are supported via multiple shelf support brackets 21 on the four vertical frames 11, 12, 13, and 14 fixed to the floor section FL and the ceiling section CE.

[0028] Specifically, the storage shelf 10 includes four vertical frames 11, 12, 13, and 14, a first horizontal frame 16, a second horizontal frame 17, a third horizontal frame 18, a plurality of shelf support brackets 21, and a plurality of shelf boards 22. Hereinafter, the four vertical frames 11, 12, 13, and 14 will be described as the first vertical frame 11, the second vertical frame 12, the third vertical frame 13, and the fourth vertical frame 14.

[0029] <First vertical frame> The first vertical frame 11 is located on the left front side of the storage shelf 10. The first vertical frame 11 includes a vertical frame main body 24, a support 25, a cylindrical portion 26, a contact portion 27, and a compression spring . The vertical frame body 24 is hollow and made of square steel pipes for machine structures. The vertical frame body 24 extends upward (in the vertical direction) with its lower end (one end) abutting against the floor section FL (one of the lower fixed section and the upper fixed section). The vertical frame body 24 includes a first frame body 31 and a second frame body 32.

[0030] Fig. 3 is a side view showing a state in which the first vertical frame and the second vertical frame of the first embodiment are connected by the first horizontal frame, and Fig. 4 is a perspective view showing a first connecting portion formed on the first frame main body of the first embodiment. 2 to 4, the first frame body 31 forms, for example, the lower half of the first vertical frame 11 (i.e., one end side of the first vertical frame 11). The first frame body 31 is a frame in which a main portion 34, excluding an upper end portion, is formed hollow. The main portion 34 of the first frame body 31 has, for example, peripheral walls formed in a rectangular cross section with the same width dimension, a front wall 34a, a rear wall 34b, a left side wall 34c, and a right side wall 34d, and a hammer-in type lower contact portion 35 is fixed to a lower end portion 34e.

[0031] The first frame body 31 has a plurality of first mounting holes (mounting holes) 37 formed at intervals in the up-down direction (i.e., axial direction) in the right wall 34d of the main portion 34. The first frame body 31 also has a plurality of first mounting holes (mounting holes) 38 (shown in FIG. 15) formed at intervals in the up-down direction (i.e., axial direction) in the left wall 34c of the main portion 34. The first mounting holes 38 are formed in the same shape as the first mounting holes 37. The first mounting holes 37 will be described in detail later. The first mounting holes 38 will be described in detail in the second embodiment.

[0032] Furthermore, the first frame body 31 has a first connecting portion 41 that protrudes in the axial direction from, for example, the upper end of the main portion 34 (i.e., the end opposite to one end of the first vertical frame 11). The first connecting portion 41 has, for example, a peripheral wall formed with a rear wall 41a, a left side wall 41b, and a right side wall 41c, with a U-shaped cross section. The first connecting portion 41 has a guide hole 42 formed in the right side wall 41c. The first connecting portion 41 also has a guide hole 43 (see FIG. 16) formed in the left side wall 41b. The guide hole 43 is formed in the same shape as the guide hole 42. The guide hole 42 will be described in detail later. The guide hole 43 will be described in detail in the second embodiment.

[0033] FIG. 5 is a side view showing the second frame main body of the first embodiment. As shown in FIGS. 2 and 5, the second frame main body 32 forms, for example, the upper half of the first vertical frame 11 (i.e., the other end side of the first vertical frame 11). The second frame main body 32 is, for example, a hollow frame formed in the same rectangular cross section as the first frame main body 31. The second frame main body 32 has a second connecting portion 45 at its lower end. The second connecting portion 45 is formed so as to be connectable to the first connecting portion 41 by fitting into the first connecting portion 41 from above. By fitting the second connecting portion 45 into the first connecting portion 41, the first frame main body 31 and the second frame main body 32 are connected together to form the vertical frame main body 24 (see also FIG. 1).

[0034] Additionally, a nut 46 is fixed to the rear wall 32a at the upper end of the second frame body 32, and a through hole 49 (see FIG. 7) is formed opposite the screw hole of the nut 46. The second frame body 32 has a plurality of second mounting holes (mounting holes) 47 formed in the right wall 32c at intervals in the up-down direction (i.e., the axial direction). Hereinafter, the lowest second mounting hole 47 among the plurality of second mounting holes 47 (i.e., the second mounting hole 47 of the second connecting portion 45) will be described as the second mounting hole 47A. The second mounting hole 47A of the second connecting portion 45 is formed in a position facing the guide hole 42 of the first connecting portion 41 in the first frame main body 31. In other words, the guide hole 42 is formed in a position facing the second mounting hole 47A. The nut 46 and the second mounting hole 47 will be described in detail later.

[0035] The second frame main body 32 has a plurality of second mounting holes (mounting holes) 48 (shown in FIGS. 16 and 17) formed in the left side wall 32b at intervals in the vertical direction (i.e., the axial direction). Hereinafter, the lowest second mounting hole 48 of the plurality of second mounting holes 48 (i.e., the second mounting hole 48 of the second connecting portion 45) will be described as second mounting hole 48A. A guide hole 43 is formed in a position facing second mounting hole 48A. The second mounting holes 47 and 48 are formed in the same shape. The second mounting holes 47 and 48 are also formed in the same shape as the first mounting holes 37 and 38. The second mounting holes 48 will be described in detail in the second embodiment.

[0036] Fig. 6 is a perspective view showing an upper constituent member of the first vertical frame of the first embodiment. Fig. 7 is a cross-sectional view of the upper constituent member of Fig. 6 taken along line VII-VII. Fig. 8 is a cross-sectional view of the upper constituent member of Fig. 6 taken along line VIII-VIII. As shown in FIGS. 6 to 8, the support pillar 25 is inserted into the upper end of the second frame body 32 (i.e., the other end of the vertical frame body) so as to be slidable in the axial direction. The support pillar 25 is formed with an H-shaped cross section. Specifically, the support pillar 25 has a pair of flanges 25a and a web 25b. The web 25b connects the central portions of the pair of flanges 25a. As a result, the support pillar 25 is formed with an H-shaped cross section by the pair of flanges 25a and the web 25b.

[0037] The support pillar 25 is arranged so that one of the pair of flanges 25a faces the front wall 32d of the second frame main body 32, and the other of the pair of flanges 25a faces the rear wall 32a of the second frame main body 32. One of the pair of flanges 25a is the front flange 25a, and the other of the pair of flanges 25a is the rear flange 25a. In this state, the fixing screw 51 is screwed into the nut 46 of the second frame body 32 and passes through the through-hole 49 in the rear wall 32a. Therefore, the tip of the fixing screw 51 abuts against the rear flange 25a. As a result, the support column 25 is fixed in a predetermined position when inserted into the upper end of the second frame body 32.

[0038] Furthermore, when the support pillar 25 is inserted into the upper end of the second frame main body 32, the web 25b is positioned so as to face the left side wall 32b and the right side wall 32c of the second frame main body 32 (i.e., the vertical frame main body 24) at a distance. Furthermore, the support column 25 has a screw hole 53 formed in the web 25b at the tip (upper end) 25c. The reason for disposing the web 25b at a distance from the left side wall 32b and the right side wall 32c of the second frame body 32 will be explained in detail later. Also, the reason for forming the screw holes 53 in the web 25b will be explained in detail later.

[0039] Fig. 9 is a side view showing an upper constituent member of the first vertical frame of the first embodiment. Fig. 10 is a cross-sectional view of the upper constituent member of Fig. 9 taken along line XX. Fig. 11 is a perspective view showing a tubular portion of the first embodiment. 9 to 11, the cylindrical portion 26 is fitted from above into the tip portion 25c that protrudes upward from the upper end of the second frame main body 32 (i.e., the vertical frame main body 24) of the support 25. The cylindrical portion 26 is made of, for example, ABS resin, and has an attachment portion 55, an expansion portion 56, and a receiving portion 57.

[0040] The mounting portion 55 is formed, for example, with a hollow rectangular cross section so that it can be fitted into the tip portion 25c of the support 25, and its tip is closed by a mounting top 58. The mounting portion 55 has a through-hole 61 (see also FIG. 8) formed in its right side wall 55a. A lock screw 62 is inserted into the through-hole 61 and threadedly engages with the threaded hole 53 of the web 25b. As a result, the mounting portion 55 is fixed (attached) in a state where it is fitted into the tip portion 25c of the support 25.

[0041] Furthermore, the mounting portion 55 has a protrusion 63 that protrudes downward from the lower edge of the rear wall 55b. The protrusion 63 is formed so as to be able to come into contact with the upper end portion (specifically, the rear wall 32a) of the second frame main body 32 (see FIG. 9). Therefore, when the protrusion 63 comes into contact with the rear wall 32a, a gap S can be secured between the mounting portion 55 and the second frame main body 32 (i.e., the upper end portion). As a result, for example, when an assembler extends the support column 25 toward the ceiling portion CE (see FIG. 1) and fixes it with the fixing screw 51, if the support column 25 is lowered, the protruding piece 63 can come into contact with the rear wall 32a, ensuring a gap S between the mounting portion 55 and the second frame main body 32. This prevents the assembler's fingers from being pinched between the mounting portion 55 and the second frame main body 32.

[0042] An enlarged portion 56 is formed integrally with the tip of the mounting portion 55. The enlarged portion 56 is formed hollow and, for example, enlarged at an angle relative to the axial direction as it extends from the tip (mounting top portion 58) of the mounting portion 55 in the axial direction. Therefore, the tip 56a of the enlarged portion 56 is greatly enlarged in a direction perpendicular to the axial direction of the mounting portion 55. Note that the enlarged portion 56 may also be enlarged, for example, from the tip of the mounting portion 55 so as to be perpendicular to the axial direction. A receiving portion 57 is formed (provided) integrally with the tip 56a of the enlarged portion 56.

[0043] The receiving portion 57 extends in the axial direction from the tip 56a of the enlarged portion 56. The receiving portion 57 is formed into a hollow rectangular cross section so as to slidably receive the contact portion 27, which will be described later. By being provided at the tip 56a of the enlarged portion 56, the receiving portion 57 is greatly enlarged in the direction perpendicular to the axial direction compared to the mounting portion 55. The receiving portion 57 has a left wall 57a and a right wall 57b each having an elongated hole 65. The elongated hole 65 extends in the vertical direction. The elongated hole 65 will be described in detail later.

[0044] FIG. 12 is a perspective view showing a contact portion of the first embodiment. 10 and 12, the contact portion 27 is made of, for example, ABS resin and includes a contact body 67 and a contact top 68. The contact body 67 is hollow and rectangular in cross section so that it can slide when inserted inside the receiving portion 57. The receiving portion 57 is greatly enlarged in a direction perpendicular to the axial direction. Therefore, the contact body 67 is also greatly enlarged in a direction perpendicular to the axial direction.

[0045] The tip (upper end) of the contact main body 67 is closed by a contact top 68. The contact top 68 protrudes in a direction intersecting the axial direction so as to be able to abut against the tip 57c of the receiving portion 57. Therefore, the contact top 68 is formed larger in the direction perpendicular to the axial direction than the mounting portion 55. The contact top 68 has a flat upper surface (surface) 68a so as to be able to abut against the ceiling portion CE (the other of the lower fixing portion and the upper fixing portion) shown in FIG. By forming the contact top 68 large in the direction perpendicular to the axial direction, the contact top 68 can be held stably on the ceiling portion CE. Note that the contact top 68 may be formed so that the friction resistance of the upper surface 68a is higher than that of other portions. A protrusion 71 protrudes downward in the axial direction from the back surface of the contact top 68.

[0046] Furthermore, stopper protrusions 73 are formed on the left and right walls 67a and 67b of the contact body 67. The stopper protrusions 73 have upwardly sloping portions 73a formed on the lower portions. The stopper protrusions 73 are arranged in the elongated holes 65 of the receiving portion 57 so as to be slidable up and down. Furthermore, the contact body 67 has slits 75 formed on both sides (front and rear sides) of the stopper projection 73 in the left and right walls 67a and 67b (the slit 75 in the left wall 67a is not shown).

[0047] Therefore, by pressing the stopper protrusion 73 in a direction intersecting the axial direction, the left side wall 67a and the right side wall 67b are elastically deformed inward of the contact main body portion 67, and the stopper protrusion 73 can be pushed toward the inside of the contact main body portion 67. As a result, when the contact main body portion 67 is inserted into the receiving portion 57, the inclined portion 73a of the stopper protrusion 73 abuts against the inner surface of the receiving portion 57, pushing the stopper protrusion 73 toward the inside of the contact main body portion 67 and guiding it up to the elongated hole 65. Furthermore, the stopper protrusion 73 guided up to the elongated hole 65 can be positioned in a state where it is accommodated in the elongated hole 65.

[0048] A compression spring 28 is disposed inside the contact portion 27 (specifically, the contact main body portion 67) and inside the tubular portion 26 (particularly, the receiving portion 57). The compression spring 28 is interposed in a compressed state between the mounting top portion 58 of the tubular portion 26 and the protrusion 71 of the contact portion 27. Here, the receiving portion 57 and the contact main body portion 67 are greatly expanded in a direction perpendicular to the axial direction. This allows the shape of the compression spring 28 to be secured to the required size, and the spring force of the compression spring 28 can be secured.

[0049] The compression spring 28 biases the contact portion 27 by a restoring force (spring force) in a direction away from the cylindrical portion 26. The stopper protrusion 73 abuts against the upper end of the elongated hole 65, so that the contact portion 27 is held at the upper end position P1 against the restoring force of the compression spring 28. This prevents the contact portion 27 from coming off the cylindrical portion 26 due to the spring force of the compression spring 28. In other words, the spring force of the compression spring 28 can stably hold the contact top portion 68 against the ceiling portion CE.

[0050] Furthermore, by pressing the contact top 68 and pushing the contact portion 27 into the receiving portion 57, the contact top 68 comes into contact with the tip 57c of the receiving portion 57. As the contact top 68 comes into contact with the tip 57c of the receiving portion 57, the first vertical frame 11 is held at the lower end position P2 against the restoring force of the compression spring 28. In this state, the first vertical frame 11 is held in a state in which it is tensioned against the floor FL and ceiling CE of the room (see FIG. 1).

[0051] Furthermore, by arranging the stopper protrusion 73 in the elongated hole 65, the assembler can visually check the position of the stopper protrusion 73. As a result, by visually checking the position of the stopper protrusion 73 during assembly work, the assembler can easily check the compressed state of the compression spring 28.

[0052] <Second vertical frame, third vertical frame, fourth vertical frame,> 1 and 2, the second vertical frame 12, the third vertical frame 13, and the fourth vertical frame 14 are configured in the same manner as the first vertical frame 11. Therefore, the components of the second vertical frame 12, the third vertical frame 13, and the fourth vertical frame 14 are given the same reference numerals as the first vertical frame 11, and detailed explanations will be omitted. Hereinafter, the first vertical frame 11, the second vertical frame 12, the third vertical frame 13, and the fourth vertical frame 14 may be collectively referred to as the "first to fourth vertical frames 11 to 14."

[0053] <First horizontal frame> 2 and 3, a first horizontal frame 16 is connected to the lower end of each of the first frame main body 31 of the first vertical frame 11 and the first frame main body 31 of the second vertical frame 12. The first horizontal frame 16 is, for example, a hollow frame formed with a rectangular cross section. By connecting the first frame bodies 31 of the first vertical frame 11 and the second vertical frame 12 at their lower ends with the first horizontal frame 16, the first vertical frame 11 and the second vertical frame 12 can be reinforced by the first horizontal frame 16.

[0054] <Second horizontal frame> A second horizontal frame 17 is connected to the lower end of each of the first frame main body 31 of the third vertical frame 13 and the first frame main body 31 of the fourth vertical frame 14. The second horizontal frame 17 is, for example, a hollow frame formed with a rectangular cross section, similar to the first horizontal frame 16. By connecting the first frame bodies 31 of the third vertical frame 13 and the fourth vertical frame 14 at their lower ends with the second horizontal frame 17, the third vertical frame 13 and the fourth vertical frame 14 can be reinforced by the second horizontal frame 17.

[0055] <Third horizontal frame> FIG. 13 is a rear view showing a state in which the second frame bodies of the second vertical frame and the third vertical frame of the first embodiment are connected by the third horizontal frame. 1 and 13, a third horizontal frame 18 is connected to the upper end portions of the second frame main body 32 of the second vertical frame 12 and the second frame main body 32 of the third vertical frame 13. The third horizontal frame 18 is, for example, a hollow frame formed with a rectangular cross section. By connecting the upper ends of the second frame bodies 32 of the second vertical frame 12 and the third vertical frame 13 with the third horizontal frame 18, the second vertical frame 12 and the third vertical frame 13 can be reinforced by the third horizontal frame 18. Specifically, the third vertical frame 13 can ensure rigidity against lateral shaking of the second vertical frame 12 and the third vertical frame 13.

[0056] Furthermore, the second frame bodies 32 of the second vertical frame 12 and the third vertical frame 13 are connected at their upper ends by the third horizontal frame 18. This allows the third horizontal frame 18 to be disposed at the rear (i.e., the back side) of the storage shelf 10. In other words, it is not necessary to dispose the third horizontal frame 18 at the front (i.e., the front side) of the storage shelf 10. As a result, at the front part (ie, the near side) of the storage shelf 10, a large vertical distance L between the shelf boards 22 (described later) can be ensured without being obstructed by the third horizontal frame 18.

[0057] <Shelf support bracket> FIG. 14 is a perspective view showing the shelf support bracket of the first embodiment. 2 and 14, shelf support brackets 21 are attached to the vertical frame bodies 24 of the first vertical frame 11 and the second vertical frame 12. In addition, shelf support brackets 21 are attached to the vertical frame bodies 24 of the third vertical frame 13 and the vertical frame bodies 24 of the fourth vertical frame 14.

[0058] Here, the vertical frame main body 24 of the first vertical frame 11 is integrally formed by fitting the second connecting portion 45 of the second frame main body 32 into the first connecting portion 41 of the first frame main body 31. The first frame main body 31 has first mounting holes 37 formed at intervals in the vertical direction in the right side wall 34d of the first frame main body 31 (specifically, the main portion 34). Also, the first frame main body 31 has second mounting holes 47 formed at intervals in the vertical direction in the right side wall 32c of the second frame main body 32. That is, the vertical frame body 24 of the first vertical frame 11 has a plurality of first mounting holes 37 formed at intervals in the vertical direction in each lower half of the right side wall, and a plurality of second mounting holes 47 formed at intervals in the vertical direction in each upper half of the right side wall.

[0059] The vertical frame body 24 of the second vertical frame 12 is formed symmetrically in the front-to-rear direction with respect to the vertical frame body 24 of the first vertical frame 11. Therefore, the vertical frame body 24 of the second vertical frame 12 has a plurality of first mounting holes 37 formed at intervals in the vertical direction in each lower half of the right side wall, and a plurality of second mounting holes 47 formed at intervals in the vertical direction in each upper half of the right side wall.

[0060] The shelf support bracket 21 is formed so as to be attachable to, for example, the first mounting hole 37 and the second mounting hole 47 on the right side wall of the vertical frame main body 24 of the first vertical frame 11, and the first mounting hole 37 and the second mounting hole 47 on the right side wall of the vertical frame main body 24 of the second vertical frame 12. In addition, the shelf support bracket 21 is formed so as to be attachable to the vertical frame main body 24 of the third vertical frame 13 and the vertical frame main body 24 of the fourth vertical frame 14, for example, in the same manner as the first vertical frame 11 and the second vertical frame 12.

[0061] Specifically, the shelf support bracket 21 has a bracket body 81 and a pair of locking portions 82. The bracket body 81 is formed with a U-shaped cross section that is open at the top, and is formed with a first upright wall 84, a bottom portion 85, and a second upright wall 86. The first upright wall 84 of the bracket body 81 has locking portions 82 formed on both ends. The locking portion 82 has a protruding side 87 and an inclined side 88. The protruding side 87 protrudes horizontally (i.e., in a direction intersecting the axial direction) from the upper side at the end of the first upright wall 84 toward the outside of the bracket main body 81. The inclined side 88 is formed at the tip of the protruding side 87. The inclined side 88 is formed so as to incline toward the bracket main body 81 as it moves from the tip of the protruding side 87 in the axial direction. In other words, the locking portion 82 is formed in a V-shape by the protruding side 87 and the inclined side 88.

[0062] FIG. 15 is a cross-sectional view showing a state in which a shelf support bracket is attached to a main portion of a first frame body in the first vertical frame of the first embodiment. 15, the shelf support bracket 21 has the locking portion 82 inserted into the first mounting hole 37 from the outside of the first vertical frame 11, and the protruding edge 87 placed in the first mounting hole 37. In other words, the locking portion 82 is locked in the first mounting hole 37. In this state, the shelf support bracket 21 has the first upright wall 84 contacting the right side wall of the first vertical frame 11 (specifically, the right side wall 34d of the main portion 34). As a result, the shelf support bracket 21 is attached to the right side wall 34d of the main portion 34 of the first frame main body 31.

[0063] Here, the inclined edge 88 is formed so as to incline toward the bracket main body 81 (i.e., toward the right side wall 34d of the main part 34). Therefore, when the overhanging edge 87 moves in a direction to come out of the first mounting hole 37, the tip 88a of the inclined edge 88 abuts against the right side wall 34d of the main part 34, preventing the overhanging edge 87 from coming out of the first mounting hole 37. In other words, the shelf support bracket 21 can be reliably attached while being positioned on the right side wall 34d of the main part 34.

[0064] FIG. 16 is a cross-sectional view showing a state in which shelf support brackets are attached to the first connecting portion and the second connecting portion in the first vertical frame of the first embodiment. 16, the first vertical frame 11 has a guide hole 42 formed in the first connecting portion 41 of the first frame main body 31, and a second mounting hole 47A formed in the second connecting portion 45 of the second frame main body 32. The first vertical frame 11 is also positioned so that the guide hole 42 of the first connecting portion 41 faces the second mounting hole 47A of the second connecting portion 45.

[0065] Therefore, when attaching the shelf support bracket 21 to the first connecting portion 41 and the second connecting portion 45 of the first vertical frame 11, the locking portion 82 is inserted into the second mounting hole 47A and the guide hole 42 from the outside of the first vertical frame 11, and the protruding edge 87 is placed in the second mounting hole 47A. In other words, the locking portion 82 is locked in the second mounting hole 47A. In this state, the first upright wall 84 of the shelf support bracket 21 comes into contact with the right side wall of the first vertical frame 11 (specifically, the right side wall 32c of the second frame main body 32 (second connecting portion 45)). As a result, the shelf support bracket 21 is attached to the right side wall 32c at the second connecting portion 45 of the second frame main body 32.

[0066] Here, the inclined edge 88 is formed so as to incline toward the bracket main body 81 (i.e., toward the right side wall 41c of the first connecting portion 41). Therefore, when the overhanging edge 87 moves in a direction to come out of the second mounting hole 47A, the tip 88a of the inclined edge 88 abuts against the right side wall 32c of the second frame main body 32, preventing the overhanging edge 87 from coming out of the second mounting hole 47A. In other words, the shelf support bracket 21 can be reliably attached in a state where it is positioned on the right side wall 32c of the second frame main body 32 (second connecting portion 45) in the first vertical frame 11.

[0067] FIG. 17 is a cross-sectional view showing a state in which a shelf support bracket is attached to a portion of the second frame body where a support post is inserted into the upper end of the second frame body in the first vertical frame of the first embodiment. As shown in Figure 17, when the support pillar 25 is inserted into the upper end of the second frame main body 32, the web 25b is positioned so that it faces the left side wall 32b and the right side wall 32c of the second frame main body 32 (i.e., the vertical frame main body 24) with a gap between them.

[0068] Therefore, when attaching the shelf support bracket 21 to the right wall 32c of the second frame main body 32 of the first vertical frame 11, the locking portion 82 is inserted into the second mounting hole 47 from the outside of the first vertical frame 11, and the protruding edge 87 is placed in the second mounting hole 47. In other words, the locking portion 82 is locked in the second mounting hole 47. In this state, the locking portion 82 is positioned away from the web 25b of the support 25. Furthermore, the first upright wall 84 of the shelf support bracket 21 comes into contact with the right wall of the first vertical frame 11 (specifically, the right wall 32c of the second frame main body 32). As a result, the shelf support bracket 21 is attached to the right wall 32c of the second frame main body 32.

[0069] Here, the inclined edge 88 is formed so as to incline toward the bracket main body 81 side (i.e., toward the right side wall 32c of the second frame main body 32). Therefore, when the overhanging edge 87 moves in a direction to come out of the second mounting hole 47, the tip 88a of the inclined edge 88 abuts against the right side wall 32c of the second frame main body 32, preventing the overhanging edge 87 from coming out of the second mounting hole 47. In other words, the shelf support bracket 21 can be reliably attached in a state where it is positioned on the right side wall 32c of the second frame main body 32 in the first vertical frame 11.

[0070] 1 and 2, the locking portions 82 of the shelf support bracket 21 can be attached to the second vertical frame 12 as well, in the same way as the first vertical frame 11. Therefore, by locking the pair of locking portions 82 of the shelf support bracket 21 to the first vertical frame 11 and the second vertical frame 12, the shelf support bracket 21 can be attached to the first vertical frame 11 and the second vertical frame 12.

[0071] Furthermore, the locking portions 82 of the shelf support bracket 21 can be attached to the third vertical frame 13 and the fourth vertical frame 14, just like the first vertical frame 11. Therefore, by locking the pair of locking portions 82 of the shelf support bracket 21 to the third vertical frame 13 and the fourth vertical frame 14, the shelf support bracket 21 can be attached to the third vertical frame 13 and the fourth vertical frame 14.

[0072] A shelf board 22 is supported by shelf support brackets 21 attached to the first vertical frame 11 and the second vertical frame 12, and shelf support brackets 21 attached to the third vertical frame 13 and the fourth vertical frame 14. Hereinafter, the shelf support bracket 21 attached to the first vertical frame 11 and the second vertical frame 12 may be referred to as the "left shelf support bracket 21." Additionally, the shelf support bracket 21 attached to the third vertical frame 13 and the fourth vertical frame 14 may be referred to as the "right shelf support bracket 21."

[0073] <Shelf> Figure 18 is a perspective view of the shelf board of the first embodiment as seen from above. Figure 19 is a perspective view of the shelf board of the first embodiment as seen from below. 18 and 19, the shelf 22 has a shelf body 91, a pair of first legs 92, and a pair of second legs 93. The shelf body 91 is formed in a rectangular shape in a plan view. The first legs 92 are formed on the front and rear edges of the shelf body 91. The first leg portion 92 has a first standing piece 95 and a first horizontal piece 96. The first standing piece 95 is bent downward (i.e., in the axial direction) from the front and rear edges of the shelf board main body 91. The first horizontal piece 96 is bent horizontally (i.e., in a direction perpendicular to the axial direction) from the lower edge of the first standing piece 95 toward the shelf board main body 91. Second leg portions 93 are formed on the left and right sides of the shelf board main body 91. The second leg portions 93 are bent downward (i.e., in the axial direction) from the left and right sides of the shelf board main body 91.

[0074] 1, 15, and 19, the second leg 93 and the left end portions 92a of the pair of first legs 92 are placed from above on the left shelf support bracket 21, whereby the left end portion of the shelf board 22 is supported by the left shelf support bracket 21. Furthermore, the second leg 93 and the right end portions 92b of the pair of first legs 92 are placed on the right shelf support bracket 21, whereby the right end portion of the shelf board 22 is supported by the right shelf support bracket 21. Thus, the shelf board 22 is supported by the left shelf support bracket 21 and the right shelf support bracket 21. That is, the shelf board 22 is supported by the first vertical frame 11, the second vertical frame 12, the third vertical frame 13, and the fourth vertical frame 14 via the left shelf support bracket 21 and the right shelf support bracket 21.

[0075] Each component of the storage shelf 10 is formed with a hanging hole so that the component can be hung when being painted, thereby ensuring an even coating of the component. 13, a hanging hole 98 for hanging the second frame main body 32 during painting is formed at the upper end of the second frame main body 32. Therefore, the support pillar 25 (see FIG. 2) can be visually observed through the hanging hole 98. As a result, by visually observing the support pillar 25 through the hanging hole 98, it can be easily determined whether the support pillar 25 is properly inserted into the upper end of the second frame main body 32. In other words, the hanging hole 98 can be used as a mark to prevent the support pillar 25 from slipping out of the upper end of the second frame main body 32.

[0076] As described above, according to the storage shelf 10 of the first embodiment, the support columns 25 that are slidably inserted into the upper ends of the second frame bodies 32 in the first to fourth vertical frames 11 to 14 are formed with an H-shaped cross section, as shown in Figures 1 and 2. By forming the support columns 25 with an H-shaped cross section, the strength of the support columns 25 can be ensured and the cross-sectional shape of the support columns 25 can be kept small. This allows the vertical frame main body 24 (that is, the first to fourth vertical frames 11 to 14) to be formed thin, giving the impression of a slim design.

[0077] 2 and 10, the mounting portion 55 of the tubular portion 26 is fitted into the tip portion 25c of the support column 25. This allows the mounting portion 55 to be made thicker than the support column 25, ensuring a large cross-section of the tubular portion 26 (particularly, the receiving portion 57). This allows the cross-section of the contact portion 27 (specifically, the contact main body portion 67), which is slidably inserted into the tubular portion 26, to be made large. Furthermore, the shape of the compression spring 28 can be ensured to have the required size. This allows a large contact area of ​​the contact top portion 68 that contacts the ceiling portion CE to be ensured. As a result, the first to fourth vertical frames 11 to 14 can be reliably held in a tensioned state between the floor portion FL and the ceiling portion CE.

[0078] Furthermore, for example, by forming the frictional resistance of the upper surface 68a of the contact top 68 to be higher than that of other parts, the contact top 68 can be maintained in a state in which it is in more favorable contact with the ceiling part CE, thereby making it possible to more reliably maintain the first to fourth vertical frames 11 to 14 in a state in which they are stretched between the floor part FL and the ceiling part CE.

[0079] Furthermore, the contact main body 67 is slidably inserted into the receiving portion 57 of the tubular portion 26. Therefore, by abutting the contact top 68 against the ceiling portion CE and pushing (entering) the contact main body 67 into the receiving portion 57, the contact main body 67 can be hidden by the receiving portion 57. This makes it easy to visually confirm that the contact main body 67 has been pushed into the receiving portion 57. Therefore, it is possible to visually determine whether the contact top 68 is securely abutting against the ceiling portion CE, and the tension state of the first to fourth vertical frames 11 to 14 (see Figure 1 for the second to fourth vertical frames 12 to 14) can be easily confirmed at a glance.

[0080] Furthermore, by providing the expanding portion 56 that expands in an inclined manner in the cylindrical portion 26, it is possible to ensure an even larger cross-sectional shape of the receiving portion 57. Therefore, it is possible to form an even larger cross-section of the contact main body portion 67 that is slidably inserted into the receiving portion 57. This makes it possible to ensure an even larger cross-section of the contact top portion 68 that abuts against the ceiling portion CE. Therefore, the first to fourth vertical frames 11 to 14 are formed thin to give a slim impression, and the first to fourth vertical frames 11 to 14 can be reliably held in a tensioned state between the floor portion FL and the ceiling portion CE.

[0081] 6, 7, and 17, the web 25b of the support column 25 is disposed at a distance from the left side wall 32b and the right side wall 32c of the second frame body 32. Therefore, at the insertion portion of the second frame body 32 where the support column 25 is inserted, when the locking portion 82 of the shelf support bracket 21 is inserted into the second mounting hole 47, it is possible to prevent the locking portion 82 from interfering with the web 25b (i.e., the support column 25). As a result, even at the insertion portion of the second frame main body 32, the locking portion 82 of the shelf support bracket 21 can be locked into the second mounting hole 47, allowing the shelf support bracket 21 to be attached to the insertion portion of the second frame main body 32.

[0082] 1 and 2, the first to fourth vertical frames 11 to 14 are configured so that the first connecting portion 41 of the first frame main body 31 is connected to the second connecting portion 45 of the second frame main body 32. Therefore, the first frame main body 31 and the second frame main body 32 form the vertical frame main body 24. In other words, the vertical frame main body 24 can be divided into the first frame main body 31 and the second frame main body 32. As a result, for example, when transporting the storage shelf 10, the storage shelf 10 can be folded up small and compact, making it easier to transport. Also, for example, when disassembling and storing the storage shelf 10, the storage shelf 10 can be folded up small and compact, making it easier to store.

[0083] 2 and 16, guide hole 42 is formed in first connecting portion 41, and guide hole 42 is positioned opposite second mounting hole 47A of second connecting portion 45. Therefore, when locking portion 82 of shelf support bracket 21 is locked into second mounting hole 47A, locking portion 82 can be inserted into second mounting hole 47A and guide hole 42 at the same time. As a result, with the second connecting portion 45 connected to the first connecting portion 41, the locking portion 82 of the shelf support bracket 21 can be locked into the second mounting hole 47A of the second connecting portion 45. Therefore, the shelf support bracket 21 can be attached to the second connecting portion 45.

[0084] Second Embodiment The storage shelf of the second embodiment will be described below with reference to Figures 20 to 23. In the second embodiment, the same or similar members as those in the storage shelf 10 of the first embodiment will be given the same reference numerals and detailed description thereof will be omitted. <Storage shelf> FIG. 20 is a perspective view showing a storage shelf according to the second embodiment. As shown in Figure 20, the storage shelf 100 includes, in addition to the storage shelf 10 of the first embodiment, a fifth vertical frame (vertical frame) 102, a sixth vertical frame (vertical frame) 103, a fourth horizontal frame 104, a plurality of shelf support brackets 21 (see Figures 21 to 23), a plurality of shelf boards 107, and a plurality of side panels 108.

[0085] Hereinafter, the storage shelf 10 of the first embodiment may be referred to as the "first storage shelf 10." In the first storage shelf 10, the distance between the first vertical frame 11 and the fourth vertical frame 14 is set to L1, and the distance between the second vertical frame 12 and the third vertical frame 13 is also set to L1. Furthermore, the "left shelf support bracket 21" provided on the storage shelf 10 of the first embodiment may be described as the "first shelf support bracket 21A (see Figures 21 to 23)." Furthermore, the locking portion 82 of the first shelf support bracket 21A may be described as the "first locking portion 82A (see Figures 21 to 23)."

[0086] <Fifth vertical frame, sixth vertical frame> The fifth vertical frame 102 is configured in the same manner as the first vertical frame 11. Therefore, the same reference numerals as those of the first vertical frame 11 are used for the components of the fifth vertical frame 102, and detailed explanations will be omitted. The fifth vertical frame 102 is disposed on the left side of the first vertical frame 11, with a distance L2 therebetween. The distance L2 is greater than the distance L1.

[0087] The sixth vertical frame 103 is configured in the same manner as the first vertical frame 11. Therefore, the same reference numerals as those of the first vertical frame 11 are used for the components of the fifth vertical frame 102, and detailed explanations will be omitted. The sixth vertical frame 103 is disposed on the left side of the second vertical frame 12, with a distance L2 therebetween.

[0088] <Fourth horizontal frame> 2 and 20, a fourth horizontal frame 104 is connected to the lower end of each of the first frame main body 31 of the fifth vertical frame 102 and the first frame main body 31 of the sixth vertical frame 103. The fourth horizontal frame 104 is, for example, a hollow frame formed with a rectangular cross section, similar to the first horizontal frame 16. By connecting the lower ends of the first frame bodies 31 of the fifth vertical frame 102 and the sixth vertical frame 103 with the fourth horizontal frame 104, the fifth vertical frame 102 and the sixth vertical frame 103 can be reinforced by the fourth horizontal frame 104.

[0089] <Second shelf support bracket, third shelf support bracket> In the storage shelf 100, multiple shelf support brackets 21 (see Figures 21 to 23) are attached at intervals in the vertical direction to the left wall of the first vertical frame 11 and the left wall of the second vertical frame 12. Hereinafter, the shelf support bracket 21 attached to the left wall of the first vertical frame 11 and the left wall of the second vertical frame 12 may be referred to as the "second shelf support bracket 21B," and the locking portion 82 of the second shelf support bracket 21B may be referred to as the "second locking portion 82B." Furthermore, the storage shelf 100 has a plurality of shelf support brackets 21 (not shown) attached at intervals in the vertical direction to the right wall of the fifth vertical frame 102 and the right wall of the sixth vertical frame 103. Hereinafter, the shelf support bracket 21 attached to the right wall of the fifth vertical frame 102 and the right wall of the sixth vertical frame 103 may be referred to as the "third shelf support bracket 21C (not shown)."

[0090] A shelf board 107 is supported by the second shelf support bracket 21B and the third shelf support bracket 21C. The shelf board 107 has a width W2 (not shown) in the left-right direction that is wider than the width W1 (not shown) of the shelf board 22, and is otherwise configured the same as the shelf board 22, except that a reinforcing member (not shown) is provided on the bottom surface facing left-right (width direction). The reinforcing member (not shown) has, for example, a hat-shaped cross section, and a pair of flanges are connected to the bottom surface by spot welding. In this way, the storage shelf 100 can be equipped with shelf boards 22 and 107 of different widths. This allows the storage shelf 100 to be used in a wider range of applications. The shelf board 22 and the shelf board 107 can be attached at different heights, or can be attached at the same height. An example in which the shelf board 22 and the shelf board 107 are attached at the same height will be described in detail with reference to Figures 21 to 23.

[0091] FIG. 21 is a cross-sectional view showing a state in which a first shelf support bracket is attached to a main portion of a first frame body in a first vertical frame of the second embodiment. 21, the first shelf support bracket 21A is engaged with the first mounting hole 37 by inserting the first locking portion 82A into the first mounting hole 37 from the outer right side of the first vertical frame 11. In this state, the first shelf support bracket 21A is attached to the right side wall 34d of the main portion 34 of the first frame body 31. The left end of the shelf board 22 is supported by the first shelf support bracket 21A. Additionally, the second shelf support bracket 21B has its second locking portion 82B inserted into the first mounting hole 38 from the outside left of the first vertical frame 11 and locked to the first mounting hole 38.

The right end of the shelf board 107 is supported by the second shelf support bracket 21B.

[0092] FIG. 22 is a cross-sectional view showing a state in which shelf support brackets are attached to the first connecting portion and the second connecting portion in the first vertical frame of the second embodiment. 22, the first vertical frame 11 is positioned so that the guide hole 42 of the first connecting portion 41 faces the second mounting hole 47A of the second connecting portion 45. Therefore, the first shelf support bracket 21A is engaged with the second mounting hole 47A by inserting the first locking portion 82A into the second mounting hole 47A and the guide hole 42 from the left outer side of the first vertical frame 11. In this state, the first shelf support bracket 21A is attached to the right side wall 32c at the second connecting portion 45 of the second frame main body 32. The left end of the shelf board 22 is supported by the first shelf support bracket 21A.

[0093] Additionally, the first vertical frame 11 is positioned so that the guide hole 43 of the first connecting portion 41 faces the second mounting hole 48A of the second connecting portion 45. Therefore, the second shelf support bracket 21B is engaged with the second mounting hole 48A by inserting the second locking portion 82B into the second mounting hole 48A and the guide hole 43 from the outer right side of the first vertical frame 11. In this state, the second shelf support bracket 21B is attached to the left side wall 32b at the second connecting portion 45 of the second frame main body 32. The right end of the shelf board 107 is supported by the second shelf support bracket 21B.

[0094] FIG. 23 is a cross-sectional view showing a state in which a shelf support bracket is attached to a portion of the upper end of the second frame body where the support post is inserted in the first vertical frame of the second embodiment. As shown in Figure 23, when the support 25 is inserted into the upper end of the second frame main body 32, the first vertical frame 11 is positioned so that the web 25b faces the left side wall 32b and the right side wall 32c of the second frame main body 32 at a distance.

[0095] Therefore, the first shelf support bracket 21A has its first locking portion 82A inserted into the second mounting hole 47 from the outer right side of the first vertical frame 11 and locked to the second mounting hole 47. Additionally, the locking portion 82 of the first shelf support bracket 21A is positioned away from the web 25b of the support column 25. In this state, the first shelf support bracket 21A is attached to the right wall 32c of the second frame main body 32. The left end of the shelf board 22 is supported by the first shelf support bracket 21A. Additionally, the second shelf support bracket 21B has its second locking portion 82B inserted into the second mounting hole 48 from the outside left side of the first vertical frame 11 and locked to the second mounting hole 48. Additionally, the locking portion 82 of the second shelf support bracket 21B is positioned away from the web 25b of the support column 25. In this state, the second shelf support bracket 21B is attached to the left wall 32b of the second frame main body 32. The right end of the shelf board 107 is supported by the second shelf support bracket 21B.

[0096] <Side panel> Figure 24 is a perspective view of the side panel of the second embodiment as seen from the front side, and Figure 25 is a perspective view of the side panel of the second embodiment as seen from the back side. As shown in Figures 24 and 25, the side panel 108 includes a side panel main body 111 and a plurality of magnet sheets 112. The side panel main body 111 has a panel 113, a pair of leg portions 114, a first bent portion 115, and a second bent portion 116. The panel 113 is formed in a rectangular shape when viewed from the side. A pair of leg portions 114 is formed on each of the front and rear edges of the panel 113.

[0097] The leg portion 114 has a first upright bending piece 121 and a second upright bending piece 122. The first upright bending piece 121 is bent in the left-right direction from the front and rear edges of the panel 113. The second upright bending piece 122 is bent in the front-rear direction from the side edge of the first upright bending piece 121. The magnet sheet 112 is fixed to the upper and lower ends of the second upright bending piece 122.

[0098] The first bent portion 115 has a first bent piece 124 and a second bent piece 125. The first bent piece 124 is bent horizontally in the left-right direction from the upper edge of the panel 113. The second bent piece 125 is bent downward from the side edge of the first bent piece 124. The second bent portion 116 is a bent edge that is bent horizontally in the left-right direction from the lower edge of the panel 113. The first bent portion 115 is formed so that it can be hooked from above onto the bottom portion 85 and second upright wall 86 (see FIG. 14) of the shelf support bracket 21. In other words, the shelf support bracket 21 not only serves to support the shelf boards 22 and 107, but also serves to hook and support the side panel 108.

[0099] As shown in FIG. 20, the first to fourth vertical frames 11 to 14, the fifth vertical frame 102, and the sixth vertical frame 103 have hollow vertical frame bodies 24 formed from square steel pipes for machine structures. Furthermore, shelf support brackets 21 can be attached to the first to fourth vertical frames 11 to 14, the fifth vertical frame 102, and the sixth vertical frame 103. Therefore, the side panels 108 are attached to the vertical frame bodies 24 of the first vertical frame 11 and the second vertical frame 12 with magnet sheets 112, for example, with the first bent portions 115 (see also FIG. 25) hooked from above onto the shelf support brackets 21. This allows the side panels 108 to separate the shelf boards 22 and 107.

[0100] The side panel 108 is attached to the vertical frame bodies 24 of the fifth vertical frame 102 and the sixth vertical frame 103, for example, by the shelf support bracket 21 or the magnetic sheet 112. This allows the left side of the shelf board 107 to be partitioned by the side panel 108. It is also possible to attach a magnetic hanger bar or the like to the side panel 108 or the vertical frame main body 24.

[0101] As described above, according to the storage shelf 100 of the second embodiment, the following functions and effects can be obtained in addition to the functions and effects of the storage shelf 10 of the first embodiment. 21, the vertical frame main body 24 of the first vertical frame 11 has a space between the left and right walls. Therefore, when the first locking portion 82A and the second locking portion 82B are formed in the same shape, the space formed between the left and right walls prevents interference between the first locking portion 82A and the second locking portion 82B. As a result, when the first locking portion 82A and the second locking portion 82B are formed in the same shape, the first shelf support bracket 21A and the second shelf support bracket 21B can be attached to the vertical frame main body 24 at the same height.

[0102] 23, the first vertical frame 11 is arranged such that the web 25b of the support pillar 25 is spaced apart from the left and right walls of the vertical frame main body 24. Therefore, at the insertion portion of the vertical frame main body 24 where the support pillar 25 is inserted, the first locking portion 82A locked in the second mounting hole 47 in the right wall and the second locking portion 82B locked in the second mounting hole 48 in the left wall can be prevented from interfering with the web 25b (i.e., the support pillar 25).

[0103] This prevents the first locking portion 82A of the first shelf support bracket 21A from interfering with the web 25b when the first locking portion 82A is inserted into the second mounting hole 47 at the insertion portion of the vertical frame main body 24 where the post 25 is inserted. Also, when the second locking portion 82B of the second shelf support bracket 21B is inserted into the second mounting hole 48 at the insertion portion of the vertical frame main body 24, it prevents the second locking portion 82B from interfering with the web 25b. Therefore, even at the insertion site of the vertical frame main body 24, with the first locking portion 82A and the second locking portion 82B formed in the same shape, the first shelf support bracket 21A and the second shelf support bracket 21B can be attached at the same height position on the vertical frame main body 24.

[0104] 22, when first locking portion 82A of first shelf support bracket 21A is locked into second mounting hole 47A, first locking portion 82A can be passed through guide hole 42. Therefore, with second connecting portion 45 connected to first connecting portion 41, first locking portion 82A of first shelf support bracket 21A can be locked into second mounting hole 47A of second connecting portion 45.

[0105] Similarly, when second locking portion 82B of second shelf support bracket 21B is locked into second mounting hole 48A, second locking portion 82B can be passed through guide hole 43. Therefore, with second connecting portion 45 connected to first connecting portion 41, second locking portion 82B of second shelf support bracket 21B can be locked into second mounting hole 48A of second connecting portion 45. This allows the first shelf support bracket 21A and the second shelf support bracket 21B, whose first and second locking portions 82A and 82B are formed in the same shape, to be attached at the same height even at the connection portion where the second connecting portion 45 is connected to the first connecting portion 41.

[0106] The technical scope of the present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the spirit of the present invention. In the above embodiment, an example was described in which the vertical frame bodies 24 of the first to fourth vertical frames 11 to 14, the fifth vertical frame 102, and the sixth vertical frame 103 are formed into hollow rectangular cross-sections, but the vertical frame bodies 24 may also be formed into other cross-sectional shapes.

[0107] In the above embodiment, an example has been described in which one end of the vertical frame body 24 abuts against the floor FL and the contact top 68 abuts against the ceiling CE, but this is not limiting. As another example, one end of the vertical frame body 24 may abut against the ceiling CE and the contact top 68 may abut against the floor FL.

[0108] Furthermore, in the above embodiment, an example has been described in which the shelf boards 22 and shelf boards 107 are supported on the vertical frame bodies 24 of the first to fourth vertical frames 11 to 14, the fifth vertical frame 102, and the sixth vertical frame 103 via the shelf support brackets 21, but this is not limiting. As another example, for example, the shelf boards 22 and shelf boards 107 may be directly supported on the vertical frame bodies 24 of the first to fourth vertical frames 11 to 14, the fifth vertical frame 102, and the sixth vertical frame 103.

[0109] Furthermore, in the second embodiment, an example was described in which the side panels 108 were attached to the left and right sides of the storage shelf 100, but the side panels 108 may also be attached to the rear side of the storage shelf 100. In this case, for example, it is necessary to provide shelf support brackets 21 on the vertical frame main bodies 24 of the sixth vertical frame 103 and the second vertical frame 12. Also, in the side panel 108, the spacing between the magnetic sheets 112 needs to be adjusted to match the spacing between the vertical frame main bodies 24 of the sixth vertical frame 103 and the second vertical frame 12. This makes it possible to attach the side panels 108 to the vertical frame main bodies 24 of the sixth vertical frame 103 and the second vertical frame 12 (i.e., the rear side of the storage shelf 100).

[0110] Additionally, although an example in which a side panel 108 is attached to the storage shelf 100 of the second embodiment has been described, the side panel 108 may also be attached to the storage shelf 10 of the first embodiment. For example, the side panel 108 may be attached to the vertical frame bodies 24 of the first vertical frame 11 and the second vertical frame 12 using shelf support brackets 21 and magnetic sheets 112. This allows the left side of the shelf board 22 to be partitioned by the side panel 108. The side panel 108 may also be attached to the vertical frame bodies 24 of the third vertical frame 13 and the fourth vertical frame 14 using shelf support brackets 21 and magnetic sheets 112. This allows the right side of the shelf board 22 to be partitioned by the side panel 108.

[0111] Furthermore, a side panel 108 may be attached to the rear side of the storage shelf 10 of the first embodiment. In this case, for example, it is necessary to provide shelf support brackets 21 on the vertical frame bodies 24 of the second vertical frame 12 and the third vertical frame 13. Also, in the side panel 108, the spacing between the magnetic sheets 112 must be adjusted to match the spacing between the vertical frame bodies 24 of the second vertical frame 12 and the third vertical frame 13. This makes it possible to attach the side panel 108 to the vertical frame bodies 24 of the second vertical frame 12 and the third vertical frame 13 (i.e., the rear side of the storage shelf 10).

[0112] In addition, within the scope of the spirit of the present invention, the components in the above-described embodiments may be replaced with well-known components as appropriate, and the above-described modifications may be combined as appropriate. [Explanation of symbols]
