Description

Technical Field

[0001] The present invention relates to a shelf receiving fitting, a shelf board installation method using the shelf receiving fitting, and an installation structure of a shelf board.

Background Art

[0002] For example, when installing a shelf board in a storage space, a horizontally long receiving bar was attached to the wall surface of the storage space, and the shelf board was placed and fixed on the receiving bar (see, for example, Patent Document 1).

[0003] However, when installing a shelf board using a receiving bar, a plurality of receiving bars of lengths corresponding to each side of the shelf board are required to support each side of the shelf board, and an adhesive and screws are required for attaching the receiving bar to the wall surface. Therefore, when using a receiving bar, the number of parts used increases, on-site processing of the receiving bar becomes necessary, and since it is a wet combined fixing using an adhesive and screws for the receiving bar, it takes time and effort.

[0004] Therefore, there has also been a practice of installing a shelf board using a fitting (shelf receiving fitting) instead of a receiving bar (see, for example, Patent Document 2).

Mode for Carrying Out the Invention

[0011] Hereinafter, this embodiment will be described in detail with reference to the drawings. FIGS. 1 to 12 are for explaining this embodiment. Among these, FIGS. 1A to 8 are Example 1 and its modification examples, FIGS. 9A to 11 are Example 2 and its modification examples, and FIG. 12 is a comparative example.

Example

[0012] <Configuration> Hereinafter, the configuration of this example will be described.

[0013] A storage space 1 is provided inside the building. For example, the storage space 1 is a storage shelf or the like in which a shelf board 3 is installed on a wall surface 2 as shown in FIGS. 1A to 1E (or a modification example of FIGS. 2A to 2C). Note that the storage space 1 in FIGS. 1A to 1E (or FIGS. 2A to 2C) will be described later.

[0014] At this time, in the storage space 1, the shelf board 3 is attached to the wall surface 2 using a shelf receiving metal fitting 4.

[0015] Here, the building can be any type. For example, the building can be a unit building or the like. A unit building is a building that can be constructed in a short period by transporting a box-shaped building unit prefabricated in a factory to a construction site and assembling it at the construction site.

[0016] The storage space 1 is preferably a closet or the like installed in a built-in state with respect to the building.

[0017] The wall 2 of the storage space 1 is made up of an interior wall of a building, a partition wall, etc. The wall 2 of the storage space 1 is made up of, for example, a rear wall 5 located at the rear side as viewed from the front, and a pair of parallel side walls 6 located on both sides of the rear wall 5 and extending from the rear side to the front side.

[0018] The wall surface 2 is, for example, formed by attaching an interior base board 8 to a mounting frame 7 and pasting wallpaper 9 on the surface of the interior base board 8. The mounting frame 7 is rectangular with upper and lower horizontal frames and left and right vertical frames, and has multiple rows of approximately horizontal support bars 11 (horizontal bars) spaced apart in the vertical direction 12 inside.

[0019] The shelf board 3 is a nearly horizontal board that divides the storage space 1 into upper and lower sections, forming shelf levels. The shelf board 3 is formed in a nearly rectangular shape in plan view, with a size that fits the storage space 1. A decorative front frame 13 can be attached to the edge of the front side of the shelf board 3.

[0020] 1A to 1E has one shelf 3 with a substantially horizontal hanger pipe 14 attached below the shelf 3. The hanger pipe 14 is attached to the shelf 3 with screws 16 via pipe mounting brackets 15.

[0021] 2A to 2C has two or more shelves 3 arranged vertically. In the figures, the lower shelf 3 is wider than the upper shelf 3. However, the size relationship between the upper and lower shelves 3 is not limited to this.

[0022] Shelf brackets 4 are metal fittings that support shelf boards 3, and it is preferable that storage space 1 basically has shelf boards 3 attached using only shelf brackets 4. The shelf brackets 4 are attached to support rails 11 inside wall surface 2 or to the vertical frame of mounting frame 7. For this reason, support rails 11 are installed at the positions where shelf boards 3 will be attached.

[0023] In addition to the basic configuration described above, this embodiment may also have the following configuration.

[0024] (1) As shown in Figure 3 (Figure 4), the shelf bracket 4 is The metal fitting body 23 has an L-shaped cross section and includes a horizontal horizontal surface portion 21 and a vertical surface portion 22 extending downward from the end of the horizontal surface portion 21. The side surface portion 21 has a first mounting hole 25 for abutting and fixing to the shelf board 3 with a fixing device 24 (FIG. 5). The vertical surface portion 22 has a second mounting hole 27 and a third mounting hole 28 for abutting and fixing to the wall surface 2 with another fixing tool 26 (FIG. 5). The first mounting hole 25 is an elongated hole extending in the extending direction 29 of the lateral surface portion 21 . The second mounting hole 27 and the third mounting hole 28 are formed at positions offset in the width direction 31 and the up-down direction 12 of the vertical surface portion 22 . The second mounting hole 27 is located above the third mounting hole 28 and is an elongated hole extending in the up-down direction 12 .

[0025] Here, the shelf bracket 4 is a metal fitting used to attach the shelf board 3 to the wall surface 2 of the storage space 1, and supports the underside of the shelf board 3 from below. The shelf bracket 4 may be plated, but it is preferable to use one that is colored the same color as the wallpaper 9 on the wall surface 2 or a similar color.

[0026] The lateral surface portion 21 is a lateral surface that is installed so as to protrude from the wall surface 2 in a substantially horizontal direction, and is in contact with the lower surface of the shelf board 3 to support the shelf board 3 from below.

[0027] The end portion is a terminal portion of the horizontal surface portion 21 that is located on the wall surface 2 side.

[0028] The vertical surface portion 22 is a vertical surface that is installed facing the up-down direction 12, and fixes the shelf support bracket 4 to the wall surface 2 while in contact with the wall surface 2. The vertical surface portion 22 is preferably formed to have the same width dimension and thickness as the horizontal surface portion 21.

[0029] The metal fitting body 23 is the main part of the shelf support metal fitting 4, and is a corner fitting shaped like a rectangular metal plate bent at an angle of approximately 90 degrees in the out-of-plane direction at the middle part.

[0030] The fasteners 24 are components that secure the shelf board 3 to the side surface portion 21 from bottom to top. Ordinary screws or the like can be used for the fasteners 24. The fasteners 24 are long enough so that they do not penetrate the shelf board 3 when the shelf board 3 is attached to the side surface portion 21. The fasteners 24 may be plated, but it is preferable that the entire fasteners 24 or at least their heads be the same color as the shelf brackets 4.

[0031] The first mounting holes 25 are holes through which fasteners 24 for fixing the shelf board 3 to the side surface portion 21 from below are passed, and are through holes in the up-down direction 12 perpendicular to the side surface portion 21 .

[0032] The other fastener 26 is a member that fixes the vertical surface portion 22 horizontally to the wall surface 2. It is preferable to use a flat head screw or the like as the other fastener 26. A flat head screw is a screw with a conical head. The surface of the head is basically flat (except for the groove for inserting a tool). The other fastener 26 is long enough so that it does not penetrate the receiving rail 11 when the vertical surface portion 22 is attached to the wall surface 2. The other fastener 26 may be plated, but it is preferable to color the entire fastener 26, or at least the head, the same color as the shelf bracket 4.

[0033] The second mounting hole 27 is a hole through which another fastener 26 passes to fix the metal fitting body 23 laterally to the wall surface 2, and is a horizontal through-hole perpendicular to the vertical surface portion 22. The second mounting hole 27 has a tapered surface 32 on the front edge that matches the conical surface of the head of a flat head screw.

[0034] The third mounting hole 28 is a hole through which another fastener 26 passes to fix the metal fitting body 23 laterally to the wall surface 2, and is a horizontal through-hole perpendicular to the vertical surface portion 22. The third mounting hole 28 has a tapered surface 32 on the front edge that matches the conical surface of the head of a flat head screw.

[0035] The extension direction 29 is a horizontal direction perpendicular to the width direction 31 of the horizontal surface portion 21. The extension direction of the vertical surface portion 22 is a direction perpendicular to the width direction 31 of the vertical surface portion 22, which is different from the extension direction 29 of the horizontal surface portion 21 and is the up-down direction 12.

[0036] The elongated hole of the first mounting hole 25 has an oval shape that extends in a horizontal direction perpendicular to the width direction 31 relative to the lateral surface portion 21 .

[0037] The width direction 31 is the direction of the width of the horizontal surface portion 21 and the vertical surface portion 22.

[0038] The vertical direction 12 is the direction connecting directly above and directly below.

[0039] The elongated hole of the second mounting hole 27 has an oval shape that extends substantially vertically relative to the vertical surface portion 22.

[0040] The third mounting hole 28 may be an elongated hole similar to the second mounting hole 27, but in this embodiment it is a round hole.

[0041] The second mounting hole 27 and the third mounting hole 28 are formed at positions that do not substantially overlap with each other in both the up-down direction 12 and the width direction 31 .

[0042] (2) In the shelf support fitting 4, the horizontal surface portion 21 may be shorter than the vertical surface portion 22. The first mounting hole 25 may be formed in the center of the width of the lateral surface portion 21 . The second mounting hole 27 is vertical surface portion 22 The dimension from the top to the center of the may be a minimum distance 44 (FIG. 5) at which a power tool 43 can be used.

[0043] Here, the horizontal surface portion 21 being shorter than the vertical surface portion 22 means that the length 41 of the horizontal surface portion 21 in the extension direction 29 is smaller than the length 42 of the vertical surface portion 22 in the extension direction (length 41 of the horizontal surface portion 21 < length 42 of the vertical surface portion 22, Figure 3).

[0044] Forming the first mounting hole 25 at the center of the width of the side surface portion 21 means that the center of the first mounting hole 25 is formed at a position equidistant from both widthwise ends of the side surface portion 21 (distance 45 = distance 46, FIG. 4(c)). This makes the side surface portion 21 symmetrical and allows it to be used in either direction.

[0045] The power tool 43 is, for example, a powered tool such as an electric screwdriver.

[0046] The minimum distance 44 is the dimension in the up-down direction 12 from the top of the body 43a of the power tool 43 to the center of a replacement tool 43b, such as a driver bit, attached to the body 43a of the power tool 43. Specifically, the minimum distance 44 is preferably set to about 20 mm (for example, between 18 mm and 24 mm). Regarding the first mounting hole 25, the dimension from the end of the side surface portion 21 on the wall surface 2 side to the center of the first mounting hole 25 may also be set to approximately the minimum distance 44. Furthermore, when the necessary adjustment amount is taken into consideration, it is preferable that the first mounting hole 25 is longer than the second mounting hole 27. For example, if the first mounting hole 25 is 10 mm, second mounting hole 27 8 It is preferable to use mm.

[0047] The vertical surface portion 22 has a length 42 that is slightly longer than the minimum distance 44 plus the length of the lower half of the second mounting hole 27 and the diameter of the third mounting hole 28. The horizontal surface portion 21 has a length 42 that is slightly longer than the minimum distance 44 plus half the length of the first mounting hole 25. 41 It is as follows.

[0048] More specifically, the vertical surface portion 22 is preferably set to a length of about 40 mm (for example, between 36 mm and 42 mm), and the horizontal surface portion 21 is preferably set to a length of about 30 mm (for example, between 28 mm and 32 mm).

[0049] A shelf board installation structure using the shelf support bracket 4 will be described below.

[0050] In this shelf board installation structure, the shelf support fittings 4 are installed on the wall surface 2 as follows.

[0051] As described above, the wall surface 2 of the storage space 1 has the rear wall 5 located on the rear side as viewed from the front, and a pair of side walls 6 located on both sides of the rear wall 5 and extending toward the front. A shelf board 3 is installed inside a space surrounded by a back wall 5 of the storage space 1 and a pair of side walls 6.

[0052] The shelf board 3 is, for example, of a size that allows a single shelf board to form one stage inside the storage space 1. In other words, the shelf board 3 is a board of a size (width and length) that exactly fits the cross section of the storage space 1. For this reason, the shelf board 3, which is rectangular in plan view, has a pair of long sides 3a, 3b whose length is approximately the same as or slightly shorter than the width of the rear wall 5 (the width of the storage space 1), and a pair of short sides 3c, 3d whose length is approximately the same as or shorter than the width of the side wall 6 (the depth of the storage space 1). A front frame 13 is attached to the long side 3a, which is the front side facing the storage space 1. For example, the long side 3b on the far side is installed facing the rear wall 5 and close to it, and the short sides 3c, 3d are installed facing the side wall 6 and close to it.

[0053] 2A to 2C, when multiple shelf levels are formed inside storage space 1 at intervals in vertical direction 12, shelf boards 3 are installed at positions of different heights in vertical direction 12. Each shelf board 3 is attached to a support rail 11 of a different height.

[0054] At least three or more shelf support fittings 4 are used for one shelf board 3, and the shelf board 3 is supported by the three or more shelf support fittings 4. The three or more shelf support fittings 4 are installed on the shelf board 3 in positions that form a polygon that surrounds the center of gravity of the shelf board 3 on the inside.

[0055] Specifically, the shelf brackets 4 are attached to at least two or all three of the three sides (for example, the long side 3b and the short sides 3c, 3d) of the shelf 3 facing the back wall 5 and the pair of side walls 6.

[0056] For example, when only three shelf brackets 4 are provided, one shelf bracket 4 is provided along the long side 3b of the shelf board 3. Another shelf bracket 4 is provided along one of the short sides 3c, 3d. The remaining shelf bracket 4 is installed along one of the sides so that, in relation to the two shelf brackets 4 described above, it forms a triangle that surrounds the center of gravity of the shelf board 3 on the inside.

[0057] In this case, it is preferable to provide three shelf support brackets 4 on all sides (for example, long side 3b and short sides 3c, 3d) if possible. However, depending on the situation, it is also possible to provide two shelf support brackets 4 on long side 3b and one on either short side 3c, 3d, or one on long side 3b and two on either short side 3c, 3d.

[0058] This allows the shelf board 3 to be supported efficiently with the fewest number of shelf support metal fittings 4. Furthermore, if more than three shelf support metal fittings 4 are provided, the shelf board 3 can be supported more firmly and reliably.

[0059] In this embodiment, the shelf support metal fittings 4 are provided at two locations on each of the short sides 3c and 3d of the shelf board 3, and at one or more locations on the long side 3b, for a total of five or more.

[0060] In this case, the shelf brackets 4 are installed at two locations on the short sides 3c and 3d, spaced apart from each other, near both ends of the short sides 3c and 3d. The number and location of the shelf brackets 4 installed at one or more locations on the long side 3b are determined by the length of the long side 3b. For example, if the long side 3b is short, one is installed in the center. If the long side 3b is long, two or more are installed spaced apart from each other. It is preferable that the multiple shelf brackets 4 supporting the long side 3b be installed in positions that are approximately symmetrical with respect to the long side 3b.

[0061] (3) A method for installing a shelf board using the shelf bracket 4 will now be described.

[0062] The shelf board installation method using the shelf bracket 4 is as follows: As shown in Fig. 6, a temporary fixing step of positioning and temporarily fixing the fitting body 23 on the wall surface 2; A reattachment step of once removing the temporarily fixed fitting body 23 from the wall surface 2, pasting the cross 9 on the wall surface 2, and then reattaching it to the wall surface 2; A final fixing step of adjusting the height 52 of the refitted fitting body 23 and finally fixing it to the wall surface 2; As shown in Fig. 7, a shelf board mounting step of placing the shelf board 3 on the finally fixed fitting body 23 and adjusting the gaps 53, 54 between the shelf board 3 and the wall surface 2 to mount the shelf board 3 on the fitting body 23 are performed in sequence.

[0063] Here, initially, the surface of the interior base board 8 before pasting the cross 9 is exposed on the wall surface 2. In the temporary fixing step, with respect to the surface of the interior base board 8, the fitting body 23 is temporarily fixed by positioning the vertical surface portion 22. The positioning is performed based on the height 52 of the fitting body 23, the distance 55 from the end of the wall surface 2 to the fitting body 23, the interval 56 between the inner portions of the fitting body 23, etc. It is preferable to perform the temporary fixing of the fitting body 23 using only the second mounting hole 27.

[0064] The cross 9 refers to wallpaper. The cross 9 is appropriately selected according to the building plan, interior situation, etc. and is pasted onto the surface of the interior base board 8 during the finishing of the wall surface 2. The cross 9 is attached to the wall surface 2 as almost an essential item.

[0065] In the reattachment step, immediately before pasting the cross 9, the fitting body 23 is once removed from the interior base board 8. Then, when pasting the cross 9 onto the surface of the interior base board 8, the position where the fitting body 23 was temporarily fixed is marked with respect to the cross 9. After pasting the cross 9 onto the surface of the interior base board 8, the vertical surface portion 22 of the fitting body 23 is refixed to the wall surface 2 using the marking as a guide. It is preferable to first perform the refixing to the wall surface 2 using only the second mounting hole 27.

[0066] The height 52 is the exact position in the vertical direction 12 of the fitting body 23.

[0067] In the actual fixing process, the height 52 of the metal fitting body 23 is precisely adjusted using the elongated second mounting hole 27, and once the correct height 52 is determined, the second mounting hole 27 and the third mounting hole 28 are used to properly fix the metal fitting body 23 to the wall surface 2.

[0068] To permanently fasten the metal fitting body 23, another fastener 26 such as a flat head screw is used in the second mounting hole 27 and the third mounting hole 28. This makes the head of the other fastener 26 flush with the surface of the vertical face portion 22 of the metal fitting body 23, making the other fastener 26 less noticeable.

[0069] Gaps 53, 54 are non-contact spaces formed between the sides of shelf 3 (short sides 3c, 3d and long side 3b) and wall 2 (rear wall 5 and side wall 6). If shelf 3 comes into contact with wall 2 during installation, the shelf 3 will damage the wallpaper 9, requiring the wallpaper 9 to be reattached. For this reason, shelf 3 is made slightly smaller than storage space 1 so that it can be installed without contacting wall 2. In this case, the size of shelf 3 is set so that the minimum gaps 53, 54 are secured so that the installation can be performed without damaging the wallpaper 9 and so that the appearance of the shelf is not marred.

[0070] The shelf boards 3 are installed in the storage space 1 so that the gaps 53, 54 between each section are uniform and even. The gaps 53, 54 are adjusted by placing the shelf boards 3 on multiple side surfaces 21 of the metal fitting bodies 23 attached at the same height 52, and then moving the shelf boards 3 sideways along the side surfaces 21. Therefore, aligning all of the metal fitting bodies 23 at the same height 52 so that they can support the shelves 3 is extremely important for the task of adjusting the gaps 53, 54. Furthermore, installing the shelves 3 so that the gaps 53, 54 between each section are uniform is extremely important for improving the appearance quality of the storage space 1.

[0071] In the shelf board mounting process, using the first mounting holes 25 which are elongated holes, the shelf board 3 set in the accurate gaps 53, 54 is fixed from below with the fixture 24 while maintaining the gaps 53, 54. When there is a deviation during the fixing or when the fixing is performed in two steps, etc., the first mounting holes 25 which are elongated holes are used to perform the final adjustment of the gaps 53, 54 midway. At this time, while pressing the shelf board 3 from above so that there is no floating between the shelf board 3 and the horizontal surface portion 21, it is fixed (force F). Since the fixture 24 is mounted from below, the head of the fixture 24 is less likely to be conspicuous from the outside, so in particular, it is not necessary to use a countersunk head screw.

[0072] In the above shelf board installation method, for example, the short sides 3c, 3d of the shelf board 3 are attached to the side walls 6 on both sides using the shelf receiving fittings 4.

[0073] Next, as shown in FIG. 8, the long side 3b of the shelf board 3 is attached to the back wall 5 using the shelf receiving fittings 4 (the other side part fitting attachment process). The attachment of the long side 3b to the back wall 5 by the shelf receiving fittings 4 is performed with respect to the shelf board 3 fixed at the accurate height 52 and gaps 53, 54 as described above. Therefore, the attachment to the long side 3b of the shelf board 3 can be performed much more easily and accurately than the attachment to the short sides 3c, 3d because no adjustment work is required.

[0074] As described above, all the shelf receiving fittings 4 are attached to the wall surface 2, and the shelf board 3 is accurately installed in the storage space 1 only by the shelf receiving fittings 4.

[0075] <Function and Effect>According to this embodiment, the following function and effect can be obtained.

[0076] (Function and Effect 1) The shelf receiving fitting 4 is a fitting for attaching the shelf board 3 to the wall surface 2. The shelf receiving fitting 4 is made of a fitting body 23 having an L-shaped cross section with a horizontal surface portion 21 and a vertical surface portion 22. The fitting body 23 abuts and fixes the vertical surface portion 22 against the wall surface 2. Then, since the horizontal surface portion 21 protrudes horizontally from the wall surface 2, it is possible to place the shelf board 3 on the horizontal surface portion 21 from above to support the shelf board 3 and fix the shelf board 3 from below in this state. Thereby, the shelf board 3 is installed on the wall surface 2 via the fitting body 23.

[0077] The fixing of the shelf board 3 to the wall surface 2 only requires the fitting body 23 and a fixing tool 24 such as a screw or another fixing tool 26 such as a countersunk head screw. Therefore, parts necessary for attaching the shelf board 3 (for example, a horizontally long receiving bar 11, etc.) can be reduced, and the number of parts can be minimized.

[0078] In addition, since the shelf receiving fitting 4 has a simple and easy-to-handle shape with only a horizontal portion 21 and a vertical portion 22, the same fitting body 23 can be used at any position on each side of the shelf board 3. Therefore, the shelf receiving fitting 4 has versatility, and the standardization of parts as a whole can be achieved, making the manufacturing, processing, and on-site construction of parts easier. Also, since the shelf receiving fitting 4 enables the attachment of the shelf board 3 by a dry construction method without using an adhesive or the like, the shelf board 3 can be easily installed and constructed in a short time.

[0079] Furthermore, by using the same (simple) fitting body 23 to support each side of the shelf board 3, the fitting body 23 itself and the gaps 53, 54 between the shelf board 3 and the wall surface 2 can be made less conspicuous from the outside.

[0080] In addition, the shelf receiving fitting 4 can easily adjust the horizontal position of the shelf board 3 (horizontal position adjustment function) by the first mounting hole 25 formed as an elongated hole.

[0081] Also, by forming the positions of the second mounting hole 27 and the third mounting hole 28 at vertically shifted positions, the shelf receiving fitting 4 can prevent the receiving bar 11 installed inside the wall surface 2 from cracking.

[0082] And by making the upper second mounting hole 27 an elongated hole extending in the vertical direction 12, the shelf receiving fitting 4 can accurately adjust the height 52 of the shelf board 3 (height 52 adjustment function).

[0083] Therefore, although the shelf receiving fitting 4 has a simple shape, it can perform both the adjustment of the height 52 and the adjustment of the gaps 53, 54 with a single fitting, making it a high-functional member equipped with a plurality of adjustment functions.

[0084] (Effect 2) The shelf support fitting 4 has a horizontal surface portion 21 shorter than the vertical surface portion 22. As a result, the shelf support fitting 4 has an overall vertically long shape, which makes it easier to enhance the stability of attachment to the wall surface 2 and effectively transmit the load from the shelf board 3 to the wall surface 2.

[0085] Also, the first mounting hole 25 is formed at the width center of the horizontal surface portion 21. Thereby, the shelf support fitting 4 can be used in either the left or right orientation. Thus, there is no need to prepare fittings for the left and right opposite orientations, and accordingly, the required number of parts is reduced.

[0086] And the second mounting hole 27 vertical surface portion 22 has a dimension from the upper part to the center that is the minimum distance 44 at which the power tool 43 can be used. Thereby, the size of the shelf support fitting 4 can be minimized. Also, even when the shelf support fitting 4 is made to have the minimum size, attachment using the power tool 43 becomes possible.

[0087] On the other hand, for example, when the shelf board 3 is attached to the wall surface 2 of the storage space 1 using a fitting 61 as in the comparative example of FIG. 12, the following problems occur.

[0088] That is, in the fitting 61 of the comparative example, the horizontal surface portion 61a is longer than the vertical surface portion 61b. Therefore, since the fitting 61 as a whole has a horizontally long shape, it is difficult to stably support the shelf board 3 and effectively transmit the load from the shelf board 3 to the wall surface 2.

[0089] Also, in the fitting 61 of the comparative example, since the first mounting hole 61c is provided at a position closer to the end of the horizontal surface portion 61a, it cannot be used in the left and right opposite orientations, and it is necessary to prepare separate fittings for left attachment and right attachment, and accordingly, the required number of parts is doubled.

[0090] Furthermore, in the fitting 61 of the comparative example, since both the second mounting hole 61d and the third mounting hole 61e are round holes, the height 52 cannot be adjusted, so it is difficult to attach the shelf board 3 at the exact height 52.

[0091] Therefore, even though the bracket 61 of the comparative example may appear to be the same as the shelf receiving bracket 4 of the embodiment at first glance, since the bracket 61 of the comparative example has many problems as described above, the shelf board 3 cannot be properly and accurately attached to the wall surface 2 of the storage space 1. On the other hand, the shelf receiving bracket 4 of the embodiment that solves the above problems has high functionality and versatility compared to the bracket 61 of the comparative example, and is optimal for accurately attaching the shelf board 3 to the wall surface 2 of the storage space 1.

[0092] (Function and Effect 3) The shelf board installation method may sequentially perform a temporary fixing step, a reinstallation step, a main fixing step, and a shelf board attachment step to attach the shelf board 3 to the wall surface 2.

[0093] Thereby, in the temporary fixing step, the metal fitting body 23 can be positioned and temporarily fixed to the wall surface 2 (interior finishing base board 8) before the cross 9 is pasted and completed.

[0094] In the reinstallation step, the metal fitting body 23 can be easily reattached to the wall surface 2 with the cross 9 pasted so as to be in the same state as when it was positioned.

[0095] In the main fixing step, the height 52 of the metal fitting body 23 can be accurately adjusted and main fixed to the wall surface 2 with the cross 9 pasted.

[0096] In the shelf board attachment step, the shelf board 3 can be placed on the metal fitting body 23 having the accurate height 52, the gaps 53, 54 between the shelf board 3 and the wall surface 2 can be accurately adjusted, and the shelf board 3 can be attached to the metal fitting body 23 in a state where the gaps 53, 54 are adjusted. As described above, it is possible to easily install the shelf board 3 accurately on the wall surface 2 with the cross 9 pasted without damaging the cross 9.

Embodiment

[0097] <Configuration> Hereinafter, the configuration of the installation structure of the shelf board 3 according to this embodiment will be described.

[0098] As shown in FIGS. 9A (~FIG. 11), A plurality of shelf boards 3 having a rectangular shape in plan view are connected. Each shelf board 3 is supported by a fitting body 23 at positions near a boundary portion 71 that contacts an adjacent shelf board 3. The boundary portion 71 between the shelf boards 3 is supported by a shelf receiving arm 72.

[0099] Here, the connection of a plurality of shelf boards 3 means that a plurality of shelf boards 3 are arranged side by side on the same shelf level. Or, it means forming the same level of shelf with a plurality of shelf boards 3.

[0100] The shelf boards 3 can be arranged in any way. For example, they can be arranged in a straight line (I-shaped arrangement (Figs. 9A and 9B)) with the long sides 3b facing the same direction. Also, the shelf boards 3 can be arranged in a bent configuration (L-shaped arrangement with two shelf boards 3 (Fig. 10), U-shaped arrangement with three shelf boards 3 (Fig. 11)) by connecting the long side 3b and the short sides 3c, 3d.

[0101] The boundary portion 71 is a side or a part of a side of the shelf board 3 that abuts against the side of an adjacent shelf board 3. For example, in the case of an I-shaped arrangement, the boundary portion 71 is the joint portion between the short sides 3c, 3d of the shelf boards 3 connected to each other and is formed to have the same length as the short sides 3c, 3d of the shelf board 3.

[0102] Also, in the case of an L-shaped arrangement with two shelf boards 3, the boundary portion 71 is the joint portion between a part of the long side 3b of one shelf board 3 and the short sides 3c, 3d of the other shelf board 3 and is formed to have the same length as the short sides 3c, 3d of the other shelf board 3.

[0103] And, in the case of a U-shaped arrangement with three shelf boards 3, the boundary portion 71 is two joint portions between a part of the long side 3b of the shelf board 3 located in the middle and the short sides 3c, 3d of the remaining two shelf boards 3 and is formed to have the same length as the short sides 3c, 3d of the remaining two shelf boards 3.

[0104] The position near the boundary portion 71 is a position close to the boundary portion 71 and away from the boundary portion 71 to such an extent that there is no hindrance to the attachment of the shelf receiving arm 72 on the side adjacent (or orthogonal) to the boundary portion 71 of each shelf board 3 and on the side (adjacent side) in contact with the wall surface 2.

[0105] As shown in Fig. 9B, the shelf receiving arm 72 is a long receiving member that supports part or all of the boundary portion 71 from below. The shelf receiving arm 72 is preferably approximately the same length as the short sides 3c, 3d of the shelf board 3, or approximately half or more of the length of the short sides 3c, 3d.

[0106] The shelf receiving arm 72 has an attachment surface 72a for the wall surface 2, a support surface 72b for the shelf board 3, and an arm body 72c that connects the attachment surface 72a and the support surface 72b. The attachment surface 72a is formed parallel to the wall surface 2 at the end of the shelf receiving arm 72 on the side of the wall surface 2. The support surface 72b is formed parallel to the shelf board 3 at the upper edge of the shelf receiving arm 72. The arm body 72c is substantially L-shaped or triangular in side view. Attachment holes for passing screws 73, 74 are provided in the support surface 72b and the attachment surface 72a.

[0107] The shelf receiving arm 72 may be configured to support and fix the boundary portions 71 between adjacent shelf boards 3 simultaneously with one. Also, the shelf receiving arm 72 may be configured to install two members that support and fix the boundary portion 71 of one shelf board 3 (connected and fixed to each other with a fixture 75 (Fig. 9B(b)) such as a rivet).

[0108] In this case, for example, using the above-described shelf board installation method, the shelf receiving fittings 4 are attached to the lower sides of the two sides (long side 3b and short sides 3c, 3d) of each shelf board 3 facing the wall surface 2 so that each shelf board 3 is supported and fixed in a flush state only by each shelf receiving fitting 4.

[0109] For example, in the case of the I-shaped arrangement in Fig. 9A, the shelf receiving fittings 4 are installed at two locations each on the short sides 3c and 3d of each shelf board 3 other than the boundary portion 71, and at two locations each on the long side 3b (including those close to the boundary portion 71). As a result, each shelf board 3 is in a state where it can be supported only by the shelf receiving fittings 4.

[0110] In the case of the L-shaped arrangement in Fig. 10, the shelf receiving fittings 4 are installed at two locations on the short sides 3c and 3d of the shelf board 3 with the short sides 3c and 3d as the boundary portion 71 (including those close to the boundary portion 71), and at two locations on the long side 3b. As a result, this shelf board 3 is in a state where it can be supported only by the shelf receiving fittings 4. For another shelf board 3 with one side portion of the long side 3b as the boundary portion 71, the shelf receiving fittings 4 are installed at two locations on the short sides 3c and 3d close to the boundary portion 71. For another shelf board 3 as well, it is made to be in a state where it can be supported only by the shelf receiving fittings 4.

[0111] In the case of the U-shaped arrangement in Fig. 11, the shelf receiving fittings 4 are installed at two locations each on both short sides 3c and 3d of the shelf board 3 with both side portions of the long side 3b as the boundary portion 71 (including those close to the boundary portion 71), and at one location on the long side 3b. As a result, this shelf board 3 is in a state where it can be supported only by the shelf receiving fittings 4. For the two other shelf boards 3 with the short sides 3c and 3d as the boundary portion 71, they are also made to be in a state where they can be supported only by the shelf receiving fittings 4.

[0112] Thereafter, in this state, the shelf receiving arm 72 is attached below the boundary portion 71 so that the boundary portion 71 is supported from below by the shelf receiving arm 72 (shelf receiving arm 72 attachment step). As a result, adjacent shelf boards 3 are in a flush state and the boundary portion 71 is supported by the shelf receiving arm 72.

[0113] In this embodiment, in the case of the I-shaped arrangement, the shelf receiving arms 72 support and fix the boundary portions 71 between two adjacent shelf boards 3 simultaneously.

[0114] Also, in the case of the L-shaped arrangement and the U-shaped arrangement, one shelf receiving arm 72 is used to directly support and fix the short sides 3c and 3d of the shelf board 3 forming the boundary portion 71 from below with the shelf receiving arm 72. And the shelf receiving arm 72 abuts the arm body 72c against the front frame 13 of the long side 3a of the other shelf board 3, and the arm body 72c and the front frame 13 are horizontally connected and fixed with screws 76 (Fig. 10(b)).

[0115] <Function and Effect>According to this embodiment, the following function and effect can be obtained.

[0116] (Function and Effect 4)In the installation structure of the shelf board 3, when a plurality of shelf boards 3 having a rectangular shape in plan view are connected, each shelf board 3 is supported by the shelf receiving fitting 4 at positions near the boundary portion 71 in contact with the adjacent shelf board 3, and the boundary portion 71 between the shelf boards 3 may be supported by the shelf receiving arm 72.

[0117] Thereby, the positions near the boundary portion 71 of the adjacent shelf boards 3 can be accurately aligned with each other by the shelf receiving fitting 4 so that the heights 52 are the same. And the boundary portion 71 of both shelf boards 3 whose heights 52 are aligned and flush can be reliably supported by the shelf receiving arm 72 to increase the support strength. Therefore, it is possible to prevent a step from occurring between the adjacent shelf boards 3 and firmly support the boundary portion 71 by the shelf receiving arm 72.
