Description

[Technical Field]

[0001] The present invention relates to a grid-like structure including a pair of first members and a second member extending between the pair of first members. [Background technology]

[0002] A grid structure described in Patent Document 1 is known. The grid structure includes a plurality of vertical bars and horizontal bars that span between the vertical bars, and the vertical bars have horizontal bar support holes through which the horizontal bars are inserted. In such a grid structure, it is believed that the horizontal bars can be attached to the vertical bars by inserting the horizontal bars into the horizontal bar support holes of the vertical bars and fastening them with pins to form the grid structure. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Utility Model Registration No. 3131017 Summary of the Invention [Problem to be solved by the invention]

[0004] In a lattice structure such as that described in Patent Document 1, if the position of the horizontal bars relative to the vertical bars is to be changed, the pin must be removed to remove the horizontal bar from the vertical bars, and then the horizontal bar must be inserted into another horizontal bar support hole and secured with a pin, making it difficult to change the position of the horizontal bar as needed.

[0005] Therefore, an object of the present invention is to provide a grid structure that allows the position of the second member relative to the first member to be easily changed as needed. [Means for solving the problem]

[0006] The grid-like structure of the present invention comprises a pair of first members extending in a first direction and facing each other in a second direction perpendicular to the first direction, and a second member positioned between the pair of first members and supported by the pair of first members, wherein the pair of first members have a pair of opposing edge portions facing each other in the second direction, the pair of opposing edge portions having a pair of support portions that support the second member, the pair of support portions being capable of supporting the second member at a plurality of support positions of the first member, the plurality of support positions including positions where the distance between the support portions is different, and the second member has a second-direction length that can be changed to match the distance between the support portions, or the second member has a plurality of types with different second-direction lengths corresponding to the different distances between the support portions.

[0007] According to this configuration, the second member having a length in the second direction corresponding to the distance between the support portions at the support position where the second member is to be attached can be placed at the support position, thereby making it possible to place the second member between the first members, thereby making it easy to change the position of the second member relative to the first members.

[0008] Furthermore, at least one of the pair of support portions may be an inclined support portion inclined with respect to a first direction, and the second member may be configured to have an inclined engagement portion that is supported by engaging with the inclined support portion in the first direction.

[0009] According to this configuration, the position of the second member can be finely changed by utilizing the inclination of the inclined support portion, making it easy to adjust the position of the second member.

[0010] Furthermore, the pair of support portions are configured to support the end portions of the second member in the second direction, and at least one of the pair of support portions has a stepped support portion extending toward the other support portion in the second direction, and the stepped support portions are arranged in multiple in the first direction, and the multiple stepped support portions can be configured to have different extension lengths in the second direction or different distances to the other support portion.

[0011] According to this configuration, the position of the second member can be changed by changing the position of the stepped support portion that supports the second member, making it easy to change the position of the second member.

[0012] The configuration may also include a fall prevention means for preventing the second member supported at the support position from moving in a third direction perpendicular to the first direction and the second direction relative to the opposing edge portion and falling off.

[0013] According to this configuration, the second member is restricted from moving in the third direction and falling off, and therefore, the second member can be prevented from falling off the first member.

[0014] The second member may be a strip whose width direction coincides with the first direction and whose length direction coincides with the second direction.

[0015] According to this configuration, deflection of the second member in the first direction can be suppressed, so that the second member is less likely to deform even when a load is applied in the first direction. [Effects of the Invention]

[0016] According to the present invention, a grid structure can be obtained in which the position of the second member relative to the first member can be easily changed as needed. [Brief explanation of the drawings]

[0018] A grid structure 1 according to one embodiment of the present invention will be described with reference to Fig. 1 to Fig. 8. For convenience of explanation, the up-down direction, left-right direction, and front-rear direction will be described based on the directions in an example of a usage state shown in Fig. 8.

[0019] 1, the grid structure 1 includes a pair of first members 2 extending in a first direction, that is, a vertical direction, a second member 3 extending in a second direction, that is, a front-rear direction, a separation restriction member 4 connected to the pair of first members 2, and a falling-off restriction means 27. In this embodiment, the falling-off restriction means 27 is provided on the first members 3. In the grid structure 1 of this embodiment, the second members 3 and the separation restriction member 4 are arranged between the first members 2 extending in the vertical direction, with a gap between them, so that the grid structure 1 is formed in a grid shape as a whole.

[0020] As shown in FIGS. 1 and 2, the first member 2 is a band-shaped plate-like body as a whole, and is arranged so that its longitudinal direction coincides with the up-down direction, its width direction coincides with the front-rear direction, and its thickness direction coincides with the left-right direction, which is a third direction. In this embodiment, the pair of first members 2 are arranged symmetrically with each other in the front-rear direction. In the following explanation, the first member 2 located on the front side will be described first. As shown in FIGS. 2 and 3, the first member 2 located on the front side is a plate-like body with a substantially constant thickness in the up-down direction. Specifically, the first member 2 includes a band-shaped first main body portion 21 extending in the up-down direction and an opposing edge portion 22 that forms the rear end portion in the front-rear direction.

[0021] The first main body portion 21 is strip-shaped and configured such that the upper and lower ends extend along the front-to-rear direction and the front and rear ends extend in a direction inclined relative to the up-down direction. Specifically, the first main body portion 21 is inclined relative to the up-down direction so that the lower side is located further rearward than the upper side.

[0022] The opposing edge portion 22 is a portion that extends in the up-down direction from the upper end to the lower end along the rear end of the first main body portion 21, and extends from the left face to the right face of the first main body portion 21. In this embodiment, the opposing edge portion 22 has a columnar shape with a substantially trapezoidal cross section perpendicular to the up-down direction, and the cross-sectional shape perpendicular to the up-down direction is the same from the upper end to the lower end. In addition, the entire rear face of the opposing edge portion 22 is configured as a support portion 23, and the support portion 23 can support the second member 3.

[0023] As shown in FIGS. 2 and 3 , the support portion 23 includes a first edge surface 24 extending rightward from the left surface of the first main body portion 21, a second edge surface 25 extending leftward from the right surface of the first main body portion 21, and a connecting edge surface 26 connecting the right end of the first edge surface 24 and the left end of the second edge surface 25. The first edge surface 24 and the second edge surface 25 are inclined in the left-right direction, with the central portion positioned rearward in the left-right direction. The connecting edge surface 26 extends along the left-right direction. The first edge surface 24, the second edge surface 25, and the connecting edge surface 26 are smooth surfaces without any protruding portion toward the rear. In other words, the support portion 23 is a rail that protrudes rearward from the first main body portion 21 and extends vertically. The support portion 23 of this embodiment is configured to be symmetrical in the left-right direction with respect to the center portion in the left-right direction. Furthermore, the support portion 23 of this embodiment is an inclined support portion 231 that is inclined in the vertical direction so that the lower side is located further rearward than the upper side. The inclined support portion 231 extends linearly and is inclined at a certain rate in the vertical direction. Specifically, in the inclined support portion 231, the first edge surface 24, the second edge surface 25, and the connecting edge surface 26 are configured as inclined surfaces so that the lower side is located further rearward than the upper side. The inclination of the support portion 23 is the same as the inclination of the first main body portion 21.

[0024] The support portion 23 also includes a fall-off prevention means 27 that prevents the supported second member 3 from moving in the left-right direction and falling off. In this embodiment, the fall-off prevention means 27 is configured by the first edge surface 24 and the second edge surface 25. Specifically, the fall-off prevention means 27 is a portion that extends in the front-rear direction, and comes into contact with the second member 3 that moves in the left-right direction, thereby preventing the second member 3 from moving in the left-right direction.

[0025] As shown in Fig. 1, the first member 2 located on the rear side is symmetrical in the front-rear direction to the first member 2 located on the front side. That is, the first member 2 located on the rear side includes a first main body portion 21 and an opposing edge portion 22. The first main body portion 21 is inclined so that the upper side is located further rearward than the lower side. The opposing edge portion 22 also includes a support portion 23, which is an inclined support portion 231 inclined in the up-down direction so that the lower side is located further forward than the upper side.

[0026] The first member 2 located on the front side and the first member 2 located on the rear side are disposed at a distance from each other so that their opposing edges 22 face each other in the front-to-rear direction. Here, the support portion 23 of the first member 2 located on the front side is an inclined support portion 231 inclined so that its lower side faces the rear side, and the support portion 23 of the first member 2 located on the rear side is an inclined support portion 231 inclined so that its lower side faces the front side. Therefore, the distance between the support portions 23 of the pair of first members 2 is shorter on the lower side than on the upper side. In this embodiment, the inclined support portion 231 is inclined at a constant rate in the vertical direction, so the distance between the support portions 23 of the pair of first members 2 is shorter on the lower side than on the upper side by a constant rate. In other words, the distance between the support portions 23 gradually becomes shorter toward the bottom, and varies depending on the vertical position. In addition, the pair of first members 2 are arranged so that the support portions 23 are spaced apart even at the lower ends, where the distance between the support portions 23 is the shortest; specifically, the distance between the support portions 23 at the shortest position is longer than the minimum length of the second member 3 described below.

[0027] 4 to 6, the second member 3 is generally band-shaped and is arranged so that its longitudinal direction coincides with the front-rear direction, its width direction coincides with the up-down direction, and its thickness direction coincides with the left-right direction. Specifically, the second member 3 includes a second main body portion 31 and a pair of second stretchable portions 32 provided at both left-right end portions of the second main body portion 31. The pair of second stretchable portions 32 have shapes symmetrical to each other in the front-rear direction.

[0028] The second main body 31 is a cylindrical body with open front and rear ends. Specifically, the second main body 31 is a rectangular tube with a rectangular cross section perpendicular to the front-rear direction. The second main body 31 has a substantially constant length in the left-right direction and a constant length in the up-down direction, and the left and right ends have shapes corresponding to the second extendable section 32.

[0029] The second extensible portion 32 has a symmetrical shape from front to back, so we will first describe the front second extensible portion 32. The second extensible portion 32 includes a second insertion portion 33 that extends frontward from the rear end portion and can be inserted into the second main body portion 31, a supported portion 34 that forms the front end portion of the second main body portion 31, and a second surface portion 35 that extends rearward from the supported portion 34 and covers the outer peripheral surface of the second insertion portion 33.

[0030] The second insertion portion 33 is a plate-like body having a constant length in the up-down direction and a constant length in the left-right direction, and is a band-like plate body extending in the front-rear direction. The second insertion portion 33 is block-shaped and large enough to be fitted into the second main body portion 31 from the front side, and is movable in the front-rear direction when fitted into the second main body portion 31. The second insertion portion 33 can be inserted into the second main body portion 31 until the second surface portion 35 abuts against the front end of the second main body portion 31. The front end of the second main body portion 31 abuts against the supported portion 34 from the rear side, and the outer circumferential surface abuts against the second surface portion 35 from the inside.

[0031] The supported portion 34 includes a first supported surface 36 extending from the left end to the right, a second supported surface 37 extending from the right end to the left, and a connecting supported surface 38 connecting the first supported surface 36 and the second supported surface 37. The first supported surface 36 and the second supported surface 37 are surfaces that incline in the left-right direction, and are inclined so that the center side in the left-right direction is located rearward. The connecting supported surface 38 is a surface that extends along the left-right direction. Furthermore, the first supported surface 36, the second supported surface 37, and the connecting supported surface 38 are smooth surfaces without any protruding portions on the rear side. In other words, the supported portion 34 is a portion that is concave from the front end to the rear. The supported portion 34 of this embodiment is configured to be symmetrical in the left-right direction with the center in the left-right direction as the base. Furthermore, the first supported surface 36, the second supported surface 37, and the connecting supported surface 38 of the supported portion 34 are configured to have the same inclination in the left-right direction as the first edge surface 24, the second edge surface 25, and the connecting edge surface 26 of the support portion 23. Furthermore, the supported portion 34 of this embodiment is an inclined engagement portion that is inclined in the up-down direction so that the lower side is located further rearward than the upper side. The inclined engagement portion extends linearly and is inclined at a constant rate in the up-down direction. Specifically, in the inclined engagement portion, the first supported surface 36, the second supported surface 37, and the connecting supported surface 38 are configured as surfaces that are inclined so that the lower side is located further rearward than the upper side. The inclination in the up-down direction of the inclined engagement portion is symmetrical to the inclination in the up-down direction of the inclined support portion 231.

[0032] The second surface portion 35 is cylindrical and located on the outer peripheral surface of the front end of the second insertion portion 33, and extends around the entire circumference of the second insertion portion 33. The second surface portion 35 is configured so that its top, bottom, and left and right surfaces are substantially flush with the top, bottom, and left and right surfaces of the second main body portion 31 when the second insertion portion 33 is fitted into the second main body portion 31. The rear end of the second surface portion 35 is a second abutting portion 351 that can abut against the front end of the second main body portion 31. The second abutting portion 351 has a shape corresponding to the front end of the second main body portion 31, and abuts against the front end of the second main body portion 31 in its entirety. The abutting of the second abutting portion 351 against the second main body portion 31 restricts rearward movement of the second extendable portion 32.

[0033] The second telescopic section 32 located on the rear side is provided symmetrically in the front-to-rear direction with the second telescopic section 32 located on the front side. Specifically, the second telescopic section 32 located on the rear side includes a second insertion section 33 that extends rearward from its front end and can be inserted into the second main body section 31, a supported section 34 that forms the rear end of the second main body section 31, and a second surface section 35 that extends frontward from the supported section 34 and covers the outer peripheral surface of the second insertion section 33. Such a second telescopic section 32 can be inserted into the second main body section 31 from the rear side, and its movement forward is restricted by a second abutment section 351, which is the front end of the second surface section 35, abutting against the rear end of the second main body section 31.

[0034] The length of the second member 3 in the front-rear direction changes when the second extendable section 32 moves relative to the second main body section 31. Specifically, when the second abutting section 351 of the second surface section 35 abuts against the second main body section 31, the length of the second member 3 in the front-rear direction is shortest, and when the second abutting section 351 is slid in a direction away from the second main body section 31, the length of the second main body section 31 in the second direction increases. Furthermore, when the second extendable section 32 is slid in a direction in which the second abutting section 351 approaches the second main body section 31 from a state in which the second main body section 31 extends in the front-rear direction, the length of the second main body section 31 in the front-rear direction decreases. Therefore, the second member 3 includes the second extendable section 32, which is a portion whose length changes when the second member 3 extends or contracts, and the second main body section 31, which is a portion whose length does not change.

[0035] The separation restriction member 4 connects the pair of first members 2 to each other and restricts the first members 2 from moving in the front-to-rear direction. The separation restriction member 4 also connects the first members 2 at two or more locations spaced apart in the vertical direction, restricting the first members 2 from moving apart in the front-to-rear direction. The separation restriction member 4 also connects the opposing edges 22 of the first members 2 to each other. The separation restriction member 4 of this embodiment includes an upper end separation restriction portion 41 that connects the upper ends of the first members 2 to each other, and a lower end separation restriction portion 42 that connects the lower ends of the first members 2 to each other. The upper end separation restriction portion 41 and the lower end separation restriction portion 42 have fixed lengths in the front-to-rear direction and are configured not to expand or contract in the front-to-rear direction.

[0036] The upper end separation restriction portion 41 has a strip shape extending in the front-rear direction and has a thickness approximately equal to the thickness of the first member 2. Furthermore, the length of the upper end separation restriction portion 41 in the front-rear direction is approximately equal to the separation distance in the front-rear direction of the upper end of the first member 2. The upper end separation restriction portion 41 of this embodiment includes a strip-shaped upper end separation restriction main body portion 411 and upper end fixing portions 412 that are provided at the front and rear ends of the upper end separation restriction main body portion 411 and are fixed to the upper end of the first member 2. The upper end fixing portions 412 of this embodiment have a shape that can be fitted into the support portion 23, and are fixed to the support portion 23 when fitted into the support portion 23.

[0037] The lower end separation restricting portion 42 has a strip shape extending in the front-rear direction and has a thickness that is approximately equal to the thickness of the first member 2. Furthermore, the length of the lower end separation restricting portion 42 in the front-rear direction is approximately equal to the separation distance in the front-rear direction of the lower end of the first member 2. The lower end separation restricting portion 42 of this embodiment includes a strip-shaped lower end separation restricting main body portion 421, and lower end fixing portions 422 that are provided at the front and rear ends of the lower end separation restricting main body portion 421 and are fixed to the ends of the first member 2. The lower end fixing portions 422 of this embodiment have a shape that can be fitted into the support portion 23, and are fixed to the support portion 23 when fitted into the support portion 23.

[0038] In this way, a frame is formed by providing the separation restricting members 4 at the upper and lower ends of the pair of first members 2. The second member 3 can be placed within this frame. Specifically, as shown in FIGS. 1 and 7 , the length of the second member 3 in the front-rear direction is adjusted to the separation distance between the support portions 23 of the first member 2 at the support position where the second member 3 is placed, and the supported portions 34 are engaged with the support portions 23, thereby placing the second member 3 between the pair of first members 2. To engage the supported portions 34 with the support portions 23, the second member 3 is moved from above to below, and the supported portions 34 are fitted into the support portions 23 from above. Here, the support portions 23 are rails that are convex toward the other support portion 23 in the front-rear direction and extend in the up-down direction. The supported portions 34 are configured to be concave in the front-rear direction away from the support portions 23. Therefore, the concave portions of the supported portions 34 fit along the convex portions of the support portions 23, allowing the second member 3 to be moved downward. This makes it easy to lock the second member 3 to the supporting portion 23. In addition, after aligning the second member 3 with the desired installation position relative to the pair of first members 2, the second extendable portion 32 is moved to extend the second member 3, thereby locking the supported portion 34 to the supporting portion 23, and attaching the first member 2 to the second member 3.

[0039] When the second member 3 is disposed between the pair of support portions 23, the distance between the support portions 23 of the pair of first members 2 becomes shorter toward the bottom, causing the side surfaces of the second member 3 to abut against the support portions 23, thereby restricting downward movement. Therefore, the second member 3 is supported by the support portions 23 at a position corresponding to the length of the second member 3. Furthermore, since the support portions 23 are provided with the fall-off prevention means 27, when the supported second member 3 attempts to move left or right, the supported portion 34 abuts against the fall-off prevention means 27, restricting the left or right movement, thereby preventing the second member 3 from falling off. Specifically, when the second member 3 attempts to move leftward, the first edge surface 24 abuts against the first supported surface 36, and when the second member 3 attempts to move rightward, the second edge surface 25 abuts against the second supported surface 37, restricting the left or right movement of the second member 3.

[0040] When removing the second member 3, the second member 3 supported by the supporting portion 23 can be moved upward to release the engagement between the supporting portion 23 and the supported portion 34, thereby removing the second member 3 from the first member 2. In addition, by shortening the length of the second member 3 in the front-to-rear direction while it is supported by the supporting portion 23, the engagement between the supporting portion 23 and the supported portion 34 can also be released, allowing the second member 3 to be removed from the first member 2.

[0041] Such a grid structure 1 is used to support a storage unit 5, for example, as shown in Fig. 8. The storage unit 5 includes a pair of grid structures 1 and a drawer section 51 supported by the pair of grid structures 1. In the storage unit 5 of this embodiment, the pair of grid structures 1 are arranged so as to face each other in the left-right direction.

[0042] The drawer section 51 comprises a box-shaped drawer main body section 52 capable of storing objects, and a pair of drawer rail sections 53 connected to the lattice structure 1 and supporting the drawer main body section 52 so that it can slide in the front-to-rear direction. In this embodiment, the drawer section 51 has the drawer main body section 52 and the drawer rail sections 53 arranged in two locations spaced apart in the vertical direction.

[0043] The drawer main body 52 is box-shaped with an open top and includes a storage main body 54 capable of storing items, and rolling elements (not shown) that are provided at both left and right ends of the storage main body 54 and roll in contact with the drawer rail 53. The rolling elements roll in contact with the drawer rail 53, allowing the entire drawer main body 52 to move in the front-to-rear direction. Note that the configuration is not limited to one that includes rolling elements, and for example, the drawer main body 52 may be configured to slide along the drawer rail 53.

[0044] The pair of drawer rails 53 are rails extending in the front-rear direction and connected to the lattice structure 1 so as to face each other in the left-right direction. Specifically, one of the pair of drawer rails 53 is disposed on the right surface of the left lattice structure 1 of the pair of lattice structures 1, and the other of the pair of drawer rails 53 is disposed on the left surface of the right lattice structure 1 of the pair of lattice structures 1. In this embodiment, the pair of upper drawer rails 53 is connected to the second member 3, and the pair of lower drawer rails 53 is connected to the separation restriction member 4. Specifically, the pair of upper drawer rails 53 is connected to the second main body portion 31 of the second member 3. In this manner, the drawer rails 53 are connected to a non-extendable portion of the member extending between the pair of first members 2 in the lattice structure 1. In other words, the non-extendable portion of the member extending between the pair of first members 2 in the lattice structure 1 is an article support portion for supporting other articles.

[0045] In such a storage unit 5, the position of the drawer main body 52 in the up-down direction can be changed by changing the height of the second member 3. Therefore, the position of the drawer main body 52 can be changed according to convenience, making it easy to use.

[0046] According to the grid structure 1 configured as above, by arranging the second members 3 at the support positions, the second members 3 having a length in the second direction corresponding to the distance between the support portions 23 at the support positions where the second members 3 are to be attached, the second members 3 can be arranged between the first members 2. Therefore, the position of the second members 3 relative to the first members 2 can be easily changed.

[0047] Furthermore, since the position of the second member 3 can be changed finely by utilizing the inclination of the inclined support portion 231, the position of the second member 3 can be easily adjusted.

[0048] Furthermore, since the second member 3 is restricted from moving in the third direction and falling off, the second member 3 can be prevented from falling off the first member 2.

[0049] Furthermore, since deflection of the second member 3 in the first direction can be suppressed, the second member 3 is less likely to deform even if a load is applied in the first direction.

[0050] Furthermore, the non-stretchable portion of the member extending between the pair of first members 2 is an article support portion for supporting other articles, so that other articles can be supported without being affected by the expansion and contraction of the second member 3.

[0051] The above describes an embodiment of the present invention using an example, but the present invention is not limited to the above embodiment, and various modifications can be made within the scope that does not deviate from the gist of the present invention.

[0052] For example, while the support portion 23 has been described as an inclined support portion 231, the present invention is not limited to this configuration. The support portion 23 may be configured as a stepped support portion 232 as shown in FIG. 9 . The stepped support portion 232 includes a step portion 28 extending from one opposing edge portion 22 toward the other opposing edge portion 22, and the step portions 28 are spaced apart in the up-down direction. In this embodiment, the opposing edge portion 22 is generally inclined in the front-to-rear direction (second direction) so that the lower side is closer to the other opposing edge portion 22 than the upper side, and the extension lengths of the step portions 28 are approximately equal. Therefore, the distance between the lower step portions 28 is shorter than the distance between the upper step portions 28. In addition, the end portions of the second member 3 in the second direction have a shape corresponding to the step portions 28, and in this embodiment, the end portions extend straight along the up-down direction. In the grid structure 1 configured as described above, by placing the end of the second member 3 on the step portion 28, the lower surface of the second member 3 comes into contact with the step portion 28, and the second member 3 can be supported by the step portion 28. Therefore, by changing the position of the step support portion 232 that supports the second member 3, the position of the second member 3 can be changed.

[0053] In the configuration including the stepped support portion 232, the case where the extension lengths of the step portions 28 are equal has been described, but the present invention is not limited to this configuration, and the extension lengths of the step portions 28 may be different. For example, the opposing edge portion 22 may be configured to extend in the vertical direction, and the extension lengths of the step portions 28 may be different, so that the distances between the step portions 28 are different.

[0054] Furthermore, although the case where the length of the second member 3 is changeable has been described, the present invention is not limited to this configuration. For example, as shown in Fig. 10, a configuration may be adopted in which a plurality of non-extendable second members 3 having different lengths in the second direction are provided, and second members 3 having lengths corresponding to the separation distance between support portions 23 at the support positions where the second members 3 are arranged are arranged. Even with this configuration, by arranging second members 3 of corresponding lengths, the second members 3 can be arranged between the first members 2. Furthermore, with this configuration, the entire second member 3 can be configured as an article support portion, making it easy to use.

[0055] Furthermore, in the above description, the inclined support portions 231 are configured such that the distance between the support portions 23 at the bottom is shorter than the distance at the top, but the present invention is not limited to this configuration and the distance between the support portions 23 at the top may be shorter than the distance at the bottom. Even in this configuration, the second member 3 can be sandwiched and supported by the inclined support portions 231 by fitting the second member 3 between the inclined support portions 231.

[0056] Furthermore, although the first member 2 has been described as being symmetrical from front to back, the present invention is not limited to this configuration. For example, one inclined support portion 231 and the other inclined support portion 231 may have different inclinations, or the other support portion 23 may extend in the vertical direction (not incline). Furthermore, one support portion 23 may be an inclined support portion 231, and the other support portion 23 may be a stepped support portion 232.

[0057] Furthermore, although the grid structure 1 has been described as being configured as part of a storage unit and used to support the storage main body, it is not limited to this configuration and can be used for various purposes. For example, it can be used as a partition to separate a space, as part of decoration, or as part of furniture or fittings. Even in such cases, the position of the second member 3 can be easily changed to change the appearance, etc. Furthermore, even when the grid structure 1 is used to support an item, it is not limited to supporting the drawer portion 51 and can be used to support various items.

[0058] In addition, although the above description has been given using an example in which the fall-off prevention means 27 is convex toward the other support portion 23, the present invention is not limited to this configuration and may be configured so as to be concave toward the other support portion 23. Even in this configuration, the supported portion 34 can be configured to be able to fit into the fall-off prevention means 27, thereby preventing the second member 3 from falling off. Furthermore, the fall-off prevention means 27 may be configured as a separate member provided on the first member 2. For example, the fall-off prevention means 27 may be configured as a plate-like member extending from the left and right surfaces of the first main body portion 21 toward the other first member 2. Even in this configuration, the second member 3 can be prevented from falling off by abutting the plate-like fall-off prevention means 27 against the second member 3. Furthermore, the fall-off prevention means 27 may be configured as a plate-like member extending from the left and right surfaces of the second extendable portion 32 toward the opposite side of the second main body portion 31. In this configuration, when the second member 3 attempts to move in the left-right direction, the fall-off prevention means 27 comes into contact with the first member 2, thereby preventing the second member 3 from falling off. Furthermore, the fall-off prevention means 27 may be configured as an independent structure separate from the first member 2 and the second member 3. For example, as shown in FIG. 11 , the fall-off prevention means 27 may be configured to include a fall-off prevention fixing portion 271 that is disposed between the support portion 23 of the first member 2 and the supported portion 34 of the second member and is fixed between the first member 2 and the second member 3, and a plate-shaped fall-off prevention main body portion 272 that is connected to both left-right ends of the fall-off prevention fixing portion 271 and extends in the front-rear direction from the fall-off prevention fixing portion 271. Even in this configuration, the fall-off prevention means 27 is disposed between the first member 2 and the second member 3, and the fall-off prevention main body portion 272 can prevent the second member 3 from moving in the left-right direction relative to the first member 2, thereby preventing the second member 3 from falling off. In any case, the fall-off prevention means 27 prevents the second member 3 from moving in the left-right direction relative to the first member 2, thereby preventing the second member 3 from falling off.

[0059] Furthermore, although the first direction is the up-down direction, the second direction is the front-rear direction, and the third direction is the left-right direction, the present invention is not limited to these directions. [Explanation of symbols]
