Summary of the Invention

Problems to be Solved by the Invention

[0004] However, the above-described conventional art has the following problems. Firstly, in the shelf mounting device described in Patent Document 1, the pins are only fixed with set screws, so the strength is not sufficient. Therefore, it was necessary to install a connecting arm in a diagonal brace-like manner between the shelf-side member and the wall-side member. Moreover, in order to fix the pins with set screws, the pins had to be moved to the back of the long groove, which was time-consuming work, and there was a problem in that the shelf support could not be easily changed between the folded state and the state in use. Next, in the folding shelf support described in Patent Document 2, the sliding member provided on the shelf side member is subjected to moment loads, which presents a problem in that high strength is required not only for the wall side member and the shelf side member, but also for the sliding member. Furthermore, in the conventional shelf mounting device and folding shelf bracket described above, when in use, the shelf plate and shelf support arm are pulled up from below and unfolded to a position perpendicular to the mounting surface such as a wall, i.e., a horizontal position (the position in use). When not in use, the shelf mounting device and folding shelf bracket, respectively, have the shelf plate and shelf support arm folded into a mounting plate and mounting bracket lower than the position in use. Therefore, if items are placed on the lower part of the wall, those items will get in the way, preventing the shelf plate and shelf support arms from being pulled up to the usable position, and furthermore, preventing the shelf plate and shelf support arms from being pulled down to the folded position (unused position). In other words, conventional shelf mounting devices and folding shelf brackets had the problem that they could not effectively utilize the space below the wall, whether they were in use or not. Furthermore, in conventional folding shelf brackets, when the shelf support arm is folded when not in use, the folded width is relatively wide. That is, in folding shelf brackets, the stopper and knob provided on the shelf support arm abut against the outer surface of the web of the mounting bracket (see Figures 1 and 5 of Patent Document 2). As a result, when the shelf support arm is folded, the width is wide by the length of the stopper and knob, which does not look neat and is not aesthetically pleasing.

[0005] Therefore, the main objective of the present invention is to provide a support for a flat furniture member that can be easily changed between a folded state (unused state) and a horizontal state (used state), can effectively utilize the space below the wall, can ensure the strength of the shelf support member in the used state, and is also aesthetically pleasing. [Means for solving the problem]

[Figure 10] This is an explanatory diagram showing an example of an installation method for attaching a support for a flat furniture member of the present invention to, for example, a wall surface, where Figure 10(A) and Figure 10(B) are explanatory diagrams showing the fifth and sixth steps, respectively. [Figure 11] Figures 8(A), 8(B), and 9(A) are partially abbreviated plan views showing examples of mounting support sheets used in the first, second, and third steps. [Modes for carrying out the invention]

[0010] This support 10 for a furniture flat member can be suitably used as a furniture flat member such as a shelf, a stand, a table, or a top plate of a desk, for example. In an example of this embodiment, a shelf board is particularly used as the furniture flat member. Since this support 10 for a furniture flat member has the structure shown in the following example of the embodiment, a user alone can use the support 10 for a furniture flat member to attach a shelf board, a workbench, or the like to a desired position on an indoor wall surface or in a kitchen, and it can meet the demand for DIY (Do It Yourself), which has been attracting attention in recent years. In the following description of an example of the embodiment, as shown in, for example, Fig. 1, Fig. 2, Fig. 5, Fig. 6, Fig. 7, etc., when viewed from the viewing direction of the user who uses this support 10 for a furniture flat member, the axis in the front-rear direction (x-x axis) is defined as the front-rear axis, the axis in the left-right direction (y-y axis) is defined as the left-right axis, and the axis in the up-down direction (z-z axis) is defined as the up-down axis.

[0011] Fig. 1 is a perspective view showing an example of an embodiment of the support for a furniture flat member according to the present invention and its usage state. As shown in Fig. 1 for example, this support 10 for a furniture flat member includes a pair of left and right mounting portions 12 disposed on a vertical wall surface W in a room or the like. A pair of left and right flat member holding portions 14 are rotatably disposed on the inner surface side of the pair of left and right mounting portions 12 by a rotation mechanism 16. Between the inner surface sides of the pair of left and right mounting portions 12, for example, a horizontally long rectangular shelf board 100 is mounted. The shelf board 100 is made of wood, but other than that, those made of plastic, artificial wood, or metal such as aluminum can be appropriately used. Further, a pair of left and right cover portions 18 are disposed on the outer surface side of the pair of left and right mounting portions 12. As shown in Fig. 1 and Fig. 2, the pair of left and right flat member holding portions 14 with the shelf board 100 mounted thereon are rotatably displaced by the rotation mechanism 16 from a vertical state position (non-use state position) substantially parallel to the wall surface W to a horizontal state position (use state position) where the shelf board 100 is substantially perpendicular to the wall surface W.

[0012] First, the structure of the pair of left and right mounting portions 12 will be described below with reference to Figure 1, Figure 3, Figure 4, Figure 6 and Figure 7. As particularly shown in Figure 6 and Figure 7, the pair of left and right mounting portions 12 each include a vertically long rectangular wall mounting piece 20, and the wall mounting piece 20 has, for example, three wall-side mounting holes 22 spaced apart in its longitudinal direction. At one widthwise end (left end) of the wall mounting piece 20, a side piece 24 extending vertically forward from the one end (left end) is disposed. The side piece 24 has, for example, two cover mounting holes 26 spaced apart in its longitudinal direction. Further, at one longitudinal end (lower end) of the wall mounting piece 20, a lower surface piece 28 extending vertically inward from the one end (lower end) is disposed.

[0013] Next, the structure of the pair of left and right planar member holding portions 14 will be described. As particularly shown in Figure 6 and Figure 7, the pair of left and right planar member holding portions 14 each include a vertically long rectangular planar member mounting piece 30, and a connecting piece 32 wider than the planar member mounting piece 30 is disposed on one longitudinal end side (the lower end side as viewed in the viewing direction of Figure 6 and Figure 7) of the planar member mounting piece 30. The planar member mounting piece 30 has, for example, three planar member mounting holes 34 spaced apart in its longitudinal direction. Further, the connecting piece 32 has, at a position near one longitudinal end side (near the lower end side) and spaced apart in its longitudinal direction, for example, a first insertion hole 36 and a second insertion hole 38 each having a circular cross-section.

[0014] At one widthwise end (the front end as viewed in the viewing direction of Figure 6 and Figure 7) of the planar member mounting piece 30, a first vertical piece 40 extending vertically inward from the one end (the front end as viewed in the viewing direction of Figure 6 and Figure 7) is disposed. Further, at one longitudinal end (the lower end as viewed in the viewing direction of Figure 6 and Figure 7) of the first vertical piece 40, a second vertical piece 42 extending vertically rearward from the one end (the lower end as viewed in the viewing direction of Figure 6 and Figure 7) is disposed. In this case, in the pair of left and right planar member holding parts 14, for example as seen in Figure 1, the mounting piece 30 and connecting piece 32 for the planar member abut against one end face and the other end face in the longitudinal direction of the shelf board 100, that is, the side end face of the shelf board 100, and hold the side end face of the shelf board 100. In addition, the first vertical piece 40 abuts against the portions on one end and the other end in the longitudinal direction of the lower surface of the shelf board 100, and holds those portions of the shelf board 100. Furthermore, the second vertical piece 42 abuts against the portions on one end and the other end in the longitudinal direction of the rear end face in the width direction of the shelf board 100, and holds those portions of the shelf board 100.

[0015] On the other hand, a rotating mechanism 16 is provided on the left and right pair of mounting parts 12 and the left and right pair of planar member holding parts 14. The structure of the rotating mechanism 16 will be described below with reference to Figures 1, 2, 5, 6, and 7. The rotation mechanism 16 includes, for example, a linear first elongated hole 44 provided on the lower end side of the side pieces 24 of the pair of left and right mounting parts 12. In the first elongated hole 44, the center of one arc ac1 is denoted as o1, the center of the other arc ac2 is denoted as o2, and the line connecting centers o1 and o2 is the axis L1 of the first elongated hole 44. One arc ac1 is located near the rear end of the side pieces 24 of the pair of left and right mounting parts 12 when viewed from the user's perspective in Figure 1, and the other arc ac2 is located near the front end of the side piece 24. One arc ac1 and the other arc ac2 are each formed in a semi-circular shape.

[0016] Furthermore, the side piece 24 includes a second elongated hole 46, for example, which is arc-shaped, located near the upper part of the first elongated hole 44. In the second elongated hole 46, the center of one arc ac3 is defined as o3, and the center of the other arc ac4 is defined as o4, with the line connecting centers o3 and o4 being the arc-shaped axis L2 of the second elongated hole 46. One arc ac3 is formed in a semi-circular shape and, as viewed from the user's perspective in Figure 1, is located near the front end of the pair of left and right mounting parts 12 side pieces 24, while the other arc ac4 is formed in a roughly quarter-circular shape and is located near the rear end of the side piece 24.

[0017] Furthermore, the side piece 24 is provided so as to be connected to the upper part of the second elongated hole 46 and extending downward, and includes a third elongated hole 48, for example, which is straight and functions as a locking part. In the third elongated hole 48, the center of one arc c5 is o5, the center of the other arc c6 is o6, and the line connecting centers o5 and o6 is the axis L3 of the third elongated hole 48. One arc ac5 is formed in the shape of a semicircular arc and, as viewed from the user's perspective in Figure 1, is located near the rear end of the pair of left and right mounting parts 12 side pieces 24, while the other arc ac6 is formed in the shape of a roughly quarter-circular arc and is located near the front end of the side piece 24. In this case, the center o6 of the other arc ac6 of the third elongated hole 48 and the center o4 of the other arc ac4 of the second elongated hole 46 are in the same position, and the other arc ac6 of the third elongated hole 48 and the other arc ac4 of the second elongated hole 46 are arranged concentrically.

[0018] The first elongated hole 44 and the second elongated hole 46 are arranged to communicate with the first through-hole 36 and the second through-hole 38 of the connecting piece 32 of the planar member holding portion 14, respectively. In this case, one arc ac5 of the first elongated hole 44 is able to communicate with the first through-hole 36, and the other arc ac4 of the second elongated hole 46 or the other arc ac6 of the third elongated hole 48 is able to communicate with the second through-hole 38.

[0019] In the furniture planar member support 10 according to this embodiment, the first elongated hole 44 and the third elongated hole 48 are arranged such that the axis L1 of the first elongated hole 44 and the axis L3 of the third elongated hole 48 are arranged substantially parallel to each other, as shown in Figure 1, for example. Furthermore, the first elongated hole 44 and the third elongated hole 48 are set to incline at the same angle so as to tilt forward from the rear end to the front end of the side pieces 24 of the left and right mounting portion 12. In other words, the first elongated hole 44 and the third elongated hole 48 each have a forward-tilting posture in which they incline from the rear end edge to the front end edge of the side pieces 24 of the left and right mounting portion 12 that are attached to a vertical wall surface 100.

[0020] In one example of this embodiment, as shown in Figure 1, for example, the inclination angle α of the axis L1 of the first elongated hole 44 relative to the front end edge of the lower surface piece 28 of the pair of left and right mounting portions 12, and the inclination angle β of the axis L3 of the third elongated hole 48 relative to the front end edge of the lower surface piece 28 are set to the same angle. In the example of the embodiment shown in Figure 1, the inclination angles α and β are set to, for example, 75°.

[0021] The inclination angles α and β may be set to a range of, for example, 75° to 90°. In this case, the setting α=β=75° is based on the clearance required for the lock to engage when the shelf board 100 is moved from the use state to the non-use state. For example, α=β=90° would also be acceptable. However, from the perspective of detailed design and actual use, it becomes difficult to engage the lock unless the shelf is raised firmly to 90°. Therefore, to ensure that the lock engages without raising it to 90°, the axis L3 of the third elongated hole 48 is tilted forward (for example, tilted to α=β=75°), making it easier to engage the lock.

[0022] Furthermore, by inclining the axis L1 of the first elongated hole 44 and the axis L3 of the third elongated hole 48 with inclination angles α and β of, for example, 75° to 90°, the movement distance of the pivot portion 50 and the displacement shaft portion 52 can be increased at the same height position compared to when the axis L1 of the first elongated hole 44 and the axis L3 of the third elongated hole 48 extend in a substantially vertical direction, that is, when the axis L1 of the first elongated hole 44 and the axis L3 of the third elongated hole 48 are arranged substantially perpendicular to the horizontal plane (e.g., mounting surface) of the shelf board 100 in use. In other words, when the axis L1 of the first elongated hole 44 and the axis L3 of the third elongated hole 48 are located on a line connecting, for example, the center o2 of the other arc ac2 of the first elongated hole 44 and the center o6 of the other arc ac6 of the third elongated hole 48, the distance traveled by the pivot portion 50 and the displacement shaft portion 52 moving within the first elongated hole 44 and the third elongated hole 48 is longer when the axis L1 of the first elongated hole 44 and the axis L3 of the third elongated hole 48 are inclined (when they are in a forward-tilted position) compared with when the first elongated hole 44 and the third elongated hole 48 are located substantially perpendicular to the lower surface pieces 28 of the left and right mounting portions 12 (vertical position).

[0023] In other words, the furniture flat member support 10 according to this embodiment has the above-described configuration, which makes it possible to increase the distance required to release the lock, preventing accidental operation by infants and children (unintentional opening of the shelf board 100), and in a sense making it difficult to easily release the lock. Therefore, the configuration is designed with safety in mind, so that infants and children do not accidentally open the shelf board 100 and get injured by the shelf board 100 hitting their heads or other body parts. Of course, as the travel distance increases, the compactness of the furniture support 10 is lost. Therefore, in the actual product, the length and inclination angle of the axis L1 of the first elongated hole 44 and the axis L3 of the third elongated hole 48 are set to maintain balance.

[0024] Furthermore, in the furniture flat member support 10 according to this embodiment, as shown in Figure 1 for example, the line connecting the center o2 of the other arc ac2 of the first elongated hole 44 and the center o3 of the one arc ac3 of the second elongated hole 46 is located on a plane parallel to the main surface (upper or lower surface) of the shelf board 100 when the pair of left and right flat member holding parts 14 to which the shelf board 100 is attached are displaced by the rotation mechanism 16 to a horizontal position (usage position) that is substantially perpendicular to the wall surface W. In one example of this embodiment, the intersection angle θ between the line connecting the center o2 of the other arc ac2 of the first elongated hole 44 and the center o3 of the one arc ac3 of the second elongated hole 46 and the line connecting the center o2 of the other arc ac2 of the first elongated hole 44 and the center o6 of the other arc ac6 of the third elongated hole 48 is set to, for example, 88°.

[0025] Note that this intersection angle θ may be set in the range of, for example, 88° to 90°. In this case, the setting of intersection angle θ = 88°, like the setting of inclination angles α and β, takes into account the clearance on the manufacturing side, so ideally it is preferable to set the intersection angle θ = 90°. However, if the design is made with a setting of 90°, if manufacturing errors occur, when the shelf board 100 is displaced from the unused state to the used state, the intersection angle θ often opens to 91° or 92°, causing the shelf board 100 to tilt at an obtuse angle. Therefore, the intersection angle θ is set from the perspective of detailed design and actual use, as well as from experience. If the opening angle (intersection angle θ) of the shelf board 100 is obtuse, when a round object is placed on the surface of the shelf board 100, there is a risk that the object will roll across the surface of the shelf board 100 and fall to the floor. Conversely, if the intersection angle θ = 89° due to manufacturing tolerances, there is a risk that the object will roll towards the wall W, but since it will stop on the wall W side, there is no problem in terms of the commercial value of the furniture flat member support 10. Therefore, it is not a problem even if this difference angle θ is set in the range of, for example, 88° to 90°.

[0026] Furthermore, the rotating mechanism 16 includes a pivot portion 50 that is inserted through the first elongated holes 44 of the left and right mounting portions 12 and the first insertion holes 36 of the left and right flat member holding portions 14, and that rotatably supports the flat member mounting pieces 30 of the left and right flat member holding portions 14 on the side pieces 24 of the left and right mounting portions 12, and a displacement shaft portion 52 that is inserted through the second elongated holes 46 of the left and right mounting portions 12 and the second insertion holes 38 of the left and right flat member holding portions 14, and that rotatably supports the flat member mounting pieces 30 of the left and right flat member holding portions 14 on the side pieces 24 of the left and right mounting portions 12. In this embodiment, for example, rivets 54 are used as the pivot portion 50 and the displacement shaft portion 52, respectively. Furthermore, washers 56 are provided on one main surface and the other main surface of the side pieces 24 of the pair of left and right mounting portions 12, respectively, in the first elongated hole 44 and the first through hole 36 through which the rivets 54 are inserted. Similarly, washers 56 are provided on one main surface and the other main surface of the side pieces 24 of the pair of left and right mounting portions 12, respectively, in the second elongated hole 46 and the second through hole 38 through which the rivets 54 are inserted.

[0027] Furthermore, the rotation mechanism 16 includes a third elongated hole 48 in the left and right pair of mounting parts 12. As shown in Figure 2, when the left and right pair of planar member holding parts 14 are in the unused position, the displacement shaft 52 abuts against one of the arcs ac5 of the third elongated hole 48. Therefore, the shelf board 100 is configured to prevent the displacement of the displacement shaft 52 so that the shelf board 100 does not move from the unused position shown in Figure 2 to the used position shown in Figure 1. In other words, the third elongated hole 48 functions as a locking hole that prevents the displacement of the displacement shaft 52.

[0028] In the furniture flat member support 10 according to this embodiment, a pair of left and right cover parts 18 are attached from the outside of the side pieces 24 of a pair of left and right mounting parts 12. As shown in Figures 1, 3, 6, and 7, the cover parts 18 are attached to the wall surface W via three wall-side mounting holes 22, each using wall-side mounting screws 60. On the other hand, the shelf board 100, which serves as a flat furniture member, is attached to the mounting pieces 30 of the left and right flat member holders 14 by mounting screws 62 for flat members, via three mounting holes 34 for flat members, as shown in Figures 1, 6, and 7, and is held between the mounting pieces 30 for flat members.

[0029] Next, the method of using the furniture flat member support 10 according to this embodiment will be described below with reference to, for example, Figures 8 to 11. First, a pair of left and right mounting parts 12 and a pair of left and right flat member holding parts 14 are prepared. Also, a paper mounting support sheet S is prepared for when attaching the furniture flat member support 10 to the wall surface W. The mounting support sheet S will now be described below. Specifically, as shown in Figure 11, for example, the mounting support sheet S is formed in the shape of a horizontal rectangle, and positioning lines 80A and 80B, formed by dashed lines, are indicated on the left and right ends of its longitudinal direction (left-right direction), from the top to the bottom. Furthermore, on the left and right sides of the mounting support sheet S, there are two comment fields 82A and 82B, and two other comment fields 84A and 84B, respectively. Comment field 82A contains a comment such as "the position that will be the upper left corner of this shelf bracket (corresponding to the support for the flat furniture member 10)," and comment field 82B contains a comment such as "the position that will be the upper right corner of this shelf bracket (corresponding to the support for the flat furniture member 10)." In another comment section 84A, for example, there is a comment that says, "To determine the length of this mounting support sheet, align the left end of the furniture flat component (corresponding to shelf board 100) with this positioning line," and in another comment section 84B, for example, there is a comment that says, "To determine the length of this mounting support sheet, align the right end of the furniture flat component (corresponding to shelf board 100) with this positioning line." Furthermore, on the left and right sides of the mounting support sheet S, markings 86A and 86B indicating the drilling positions of, for example, three mounting holes are indicated, spaced apart in the vertical direction. The marks 86A for the drilling positions of one set of three mounting holes are arranged so that the lines connecting their centers lie on the same straight line and are perpendicular to the longitudinal direction of the mounting support sheet S. Similarly, the marks 86B for the drilling positions of the other set of three mounting holes are also arranged so that the lines connecting their centers lie on the same straight line and are perpendicular to the longitudinal direction of the mounting support sheet S.

[0030] Now, returning to the explanation of how to use the support 10 for the furniture flat members, the mounting support sheet S described above is attached horizontally to the wall surface W using a spirit level or the like. Furthermore, as shown in the diagram in Figure 8(A), one side of the mounting support sheet S is appropriately folded in the left-right direction to match the length of the shelf board 100 that is attached to the wall surface W. Next, as shown in Figure 8(B), the folded mounting support sheet S is attached to the desired mounting location of the shelf board 100 using masking tape T or the like. Furthermore, as shown in Figure 9(A), pilot holes for mounting are drilled in the wall W at intervals along a straight line, approximately straight in the vertical direction of the wall W, using an electric drill or the like, aligned with the markings 86A and 86B on the mounting support sheet S. Then, as shown in Figure 9(B), peel the mounting support sheet S from the wall surface W, align the pilot hole with the wall-side mounting hole 22 of the mounting part 12 of the furniture flat member support 10, and temporarily fasten the set screw. Subsequently, as shown in Figure 10(A), the shelf board 100 is placed on the first vertical piece 40 of the pair of left and right flat member holding parts 14, and the shelf board 100 is held in place by the flat member mounting piece 30, the first vertical piece 40, and the second vertical piece 42 surrounding it. Then, the shelf board 100 is fixed to the flat member mounting piece 30 with set screws through the flat member mounting holes 30. Then, as shown in Figure 10(B), the shelf board 100 is rotated toward the wall surface W, and after confirming that the shelf board 100 can be stored inside the wall mounting pieces 20, side pieces 24 and bottom piece 28 of the pair of left and right mounting parts 12, the mounting parts 12 are firmly fixed to the wall surface W.

[0031] In this furniture flat member support 10, as shown in Figure 2, it is normally folded to a vertical position approximately parallel to the wall W (the unused position). When in use, the pair of left and right flat member holders 14, to which the shelf board 100 is attached, are rotated by a rotation mechanism 16, as shown in Figures 1 and 2, to move the shelf board 100 from a vertical position approximately parallel to the wall W (the unused position) to a horizontal position approximately perpendicular to the wall W (the used position). In other words, with this furniture flat member support 10, the shelf board 100 can be lowered from a vertical position (the unused position) to a horizontal position relative to the wall W (the used position) for use, making it possible to place items below the wall, and allowing effective use of the space below the wall W, regardless of whether the shelf board 100 is in use or not.

[0032] Furthermore, in this furniture flat member support 10, due to its structure, it is necessary to support the load of the shelf board 100 (furniture flat member) like a cantilever beam. However, the left and right pair of flat member holding parts 14 to which the shelf board 100 is attached are rotatably supported at two points, the pivot part 50 and the displacement axis part 52, on the side pieces 24 of the left and right pair of mounting parts 12. This is stronger than when supported at one point, and therefore the furniture flat member support 10 can maintain the strength to withstand the moment load of the shelf board 100 (furniture flat member).

[0033] Furthermore, this furniture flat member support 10 has a small number of parts, consisting mainly of four components: a pair of left and right mounting parts 12, a pair of left and right flat member holding parts 14, a pivot part 50, and a displacement shaft part 52, and can be easily attached to a wall surface W. Furthermore, in this furniture flat member support 10, when the shelf board 100 is displaced to a vertical position (unused position), the flat member mounting piece 30, the first vertical piece 40, and the second vertical piece 42 of the pair of left and right flat member holding parts 14 can be stored inside the wall mounting piece 20 and side piece 24 of the pair of left and right mounting parts 12, surrounding them. Therefore, when not in use, the furniture flat member support 10 with the shelf board 100 attached can be compactly folded, resulting in a neat and aesthetically pleasing appearance.

[0034] Furthermore, in this furniture flat member support 10, the third elongated hole 48 functions as a locking mechanism to prevent the displacement of the displacement shaft 52, so that the shelf board 100 does not move from the unused position shown in Figure 2 to the used position shown in Figure 1. In other words, the furniture flat member support 10 is provided with a third elongated hole 48 that functions as a locking mechanism to prevent the shelf board 100 from moving and hitting the head or other body parts of infants or children who may accidentally touch the shelf board 100, thus preventing injury.

[0035] Furthermore, when displacing the pair of left and right flat member holders 14 to which the shelf board 100 is attached to a horizontal position approximately perpendicular to the wall surface W (the position in use), as shown in Figure 5, it is only necessary to lift the pair of left and right flat member holders 14 to which the shelf board 100 is attached, release the displacement shaft portion 52 from the third elongated hole 48 which acts as a locking portion to release the lock, and then lower the pair of left and right flat member holders 14 to which the shelf board 100 is attached to displace it to the position in use. Thus, the shelf board 100 can be easily displaced to the position in use. Thus, in this furniture flat member support 10, in particular, has a third elongated hole (locking elongated hole) 48 that functions as a locking part. For example, even if an infant or child carelessly tries to lower the shelf board 100, the shelf board 100 cannot be moved to the position of use unless the pair of left and right flat member holding parts 14 are lifted and the displacement shaft part 52 is disengaged from the third elongated hole 48 to release the lock. This prevents accidental injuries to infants and children, and provides excellent safety.

[0036] In other words, the furniture flat member support 10 described above can be easily changed between a folded state (not in use) and a horizontal state (in use), the space below the wall W can be effectively utilized, and strength in the state of use can be ensured, while also providing a furniture flat member support that is aesthetically pleasing, thus offering extremely excellent effects.
