Description

The present invention relates to an assembly fence that can be assembled into a wall shape by abutting the sides together. More specifically, it relates to an assembly fence that can be stacked flat with its faces facing each other when not assembled.

Conventionally, an assembly fence has been used in which a fence is constructed by assembling a plurality of pieces at a construction site. Fences with such assembled fences are not always used permanently in the built state. The fence once built may be dismantled and later used for the construction of the fence again. Therefore, it is necessary to store a large number of assembly fences in the state of individuals that are not assembled. Furthermore, it will be necessary to transport it to the construction site in that state.

As an example of such an assembled fence in consideration of convenience during storage and transportation, the guard fence described in Patent Document 1 can be mentioned. Figure 2 of the same document depicts the guard fences being stacked flat. The guard fence of the same document has a square convex portion (5a) and a concave portion (5b) formed in the frame portion (1). In the flat stacking state of FIG. 2 of the same document, the convex portion (5a) and the concave portion (5b) are fitted to each other between the guard fences. As a result, the flat stacking state does not easily collapse. Therefore, it is possible to transport this flat-stacked guard fence without worrying about it collapsing.

However, the above-mentioned conventional technique has the following problems. When actually trying to stack guard fences flat, the convex portion (5a) and the concave portion (5b) may not fit well. Of course, this is a case of stacking guard fences with the same specifications. The causes of such occurrences are individual differences in individual guard fences and aging expansion and contraction. In particular, when old and new guard fences were used in a mixed manner, it was often difficult to stack them flat. It is conceivable to stack the new and old ones separately, but there is a problem that management becomes complicated.

The present invention has been made to solve the problems of the above-mentioned conventional techniques. In other words, the problem is to provide an assembly fence that can be easily stacked flat and does not easily collapse in that state, regardless of individual differences or expansion and contraction over time.

The assembly fence in one aspect of the present invention is a polygonal flat plate, and can be assembled into a wall shape by abutting the sides together, and the assembly fence can be stacked flat with the faces facing each other. Therefore, it has an overlapping portion that comes into contact with other assembly fences during stacking, and the overlapping portion is formed with a curved surface shape portion that is oriented with respect to the position of the other assembly fence that is the stacking partner. It is something that is.

The assembly fence in the above embodiment can be stacked in a flat stack when it is not used in a state where it is assembled and has a wall shape. In the stacked body in this stacked state, the curved surface-shaped portions of the stacked portions are in contact with each other between the upper and lower assembly fences. Therefore, even if there are some individual differences or aging expansion and contraction between the assembly fences, they can be easily stacked. Therefore, it is easy to store and transport in the state of stacked bodies.

Further, in the assembly fence of the above aspect, curved surface shape portions are formed on both the front and back surfaces of the overlapped portion, and the curved surface shape portion of one surface is a convex curved surface and the curved surface shape portion of the other surface is a concave curved surface. The curvature of a concave curved surface is gentler than the curvature of a convex curved surface . When there is a relationship of curvature between the convex curved surface and the concave curved surface in this way, the stability is high even if there is a slight positional deviation in the horizontal plane between the upper and lower superposition portions. Therefore, the stacked bodies are unlikely to collapse.

It is more preferable that the assembly fence of the above aspect also has a superposition portion on one side and the opposite side in the overall shape. If this is the case, when the assembly fences are stacked flat, they will have the same shape even if they are rotated 180 ° in a horizontal plane. Therefore, it is not necessary to align the orientation of the individual assembly fences when forming the stack. Therefore, the stacking work is easy.

In the assembly fence of the above aspect, it is further desirable that the curved surface-shaped portion has an arch shape separately in the superposition portion on one side and the superposition portion on the opposite side. If this is the case, even if there is a slight dimensional difference between the upper and lower assembly fences, the stable position is the state in which the positional deviation between the superposed portions due to the dimensional difference is evenly distributed to both. Therefore, the stability of the stacked body is extremely high.

In the assembly fence having an overlapping portion on one side and the opposite side, a concave curved surface is formed on the overlapping portion on the opposite side with respect to the surface on which the convex curved surface is formed on the overlapping portion on one side. It is desirable to be. If this is the case, it is not necessary to align the front and back of the individual assembly fences when forming the stack. Therefore, the stacking work is easy.

In each aspect of the assembly fence having superpositions on one side and the opposite side, or on one side and the opposite side in the overall shape, there is a support hole for holding the support in cooperation with another assembly fence or base at the time of assembly. It is desirable that the position between the convex curved surface on one side and the concave curved surface on the other side of the superposed portion is the hollow portion of the column holding hole. In such an assembly fence, the parts related to the functions for assembly and stacking are concentrated on the edge of the end. Therefore, it is possible to take a wide range of parts where there are no restrictions on the design process.

According to this configuration, an assembly fence that can be easily stacked flat and does not easily collapse in that state is provided regardless of individual differences or expansion and contraction over time.

[First form]
Hereinafter, embodiments embodying the present invention will be described in detail with reference to the accompanying drawings. The first embodiment embodies the present invention as an assembly fence 2 shown in FIGS. 1 and 2 and a modification thereof described later. The assembly fence 2 of FIGS. 1 and 2 is for constructing a fence as shown in FIG. 1 of Patent Document 1 by combining a large number of the same fences. In this specification, the whole assembled is referred to as a "fence", and the individual pieces thereof are referred to as an "assembled fence".

FIG. 1 is a view looking down on the assembly fence 2 from above, and FIG. 2 is a view looking up from below. Therefore, if the surface appearing in FIG. 1 is the front surface (Omotemen) of the assembly fence 2, FIG. 2 is the back surface. The assembly fence 2 shown in FIGS. 1 and 2 has a substantially square flat plate shape as a whole, and frame portions 21 are arranged on four sides. The frame portion 21 imparts the strength of the assembly fence 2 as a whole. The internal portion surrounded by the frame portion 21 on all sides is the design portion 22. Although the design portion 22 is drawn as a plain one in the figure, it is a portion to which a decorative design can be appropriately applied.

Superimposing portions 23 are provided at both ends of the frame portion 21 in the X direction of the X direction and the Y direction in the drawing of the assembly fence 2. There are a total of four overlapping portions 23 in one assembly fence 2, and the assembly fences 2 are in contact with each other in the stacking body 7 (see FIG. 3) in which a plurality of assembly fences 2 are stacked in a flat stack. That is, the superposition portion 23 is a portion for superimposing the assembly fences 2 on each other.

The portion of region F in FIGS. 1 and 2 is enlarged and shown in FIGS. 4 and 5. One superposition portion 23 appears in both figures. FIG. 4 is a part of FIG. 1, that is, the front side, and FIG. 5 is a part of FIG. 2, that is, the back side. The superposition portion 23 has a substantially rectangular parallelepiped shape due to the vertical ribs 24 and 25 parallel to the X direction and the vertical ribs 26 and 27 parallel to the Y direction in the drawing. Each of the vertical ribs 24 to 27 is a portion that is not horizontal but vertical when the assembly fence 2 is placed flat (including the stack 7 in FIG. 3). Of these, the vertical ribs 24 and 25 are parallel to the frame portion 21 provided with the superposition portion 23, and the vertical ribs 26 and 27 are vertical. However, in the superposed portion 23, the positions of the ceiling surface and the bottom surface in the vertical position in the flat state are open. Therefore, the inside of the superposition portion 23 can be seen from either the top (FIG. 4) or the bottom (FIG. 5).

A cylindrical portion 28 is formed inside the superposition portion 23. The inside of the cylindrical portion 28 is hollow, and the opening 29 is formed in the vertical rib 26. The internal space of the cylindrical portion 28 and the opening 29 thereof are support holes for inserting columns for assembling the assembly fence 2 into a fence. This support hole is provided on one side of the assembly fence 2 as a whole and on the opposite side thereof. For the columns for assembling the fence, refer to “3” in FIGS. 1 and 2 of Patent Document 1. In the case of this embodiment, the support column is a member independent of the assembly fence 2, and is inserted into the support hole (opening 29, cylindrical portion 28) at the time of assembly. As a result, the columns can be made by the cooperation of the upper and lower assembly fences 2, or the assembly fence 2 and the base under it (circular ones drawn without a number in FIG. 1 of Patent Document 1, whether portable or installed. Good) will be retained in collaboration with. In this way, the upper and lower assembly fences 2 are connected to each other, or the assembly fence 2 and the base below the assembly fence 2 are connected to each other.

Further, a plurality of intermediate vertical ribs 30 are formed in the superposition portion 23 of FIGS. 4 and 5. The intermediate vertical rib 30 is provided between the vertical ribs 26 and 27 in parallel with them. However, the vertical ribs 26 and 27 are not formed to extend to the inside of the cylindrical portion 28. The feature of the assembly fence 2 of this embodiment is the shape of the upper side and the lower side of the intermediate vertical rib 30. Therefore, these will be described with reference to FIG. In FIG. 6 when the superposed portion 23 is viewed from the front, the shape of the bottom portion of the cylindrical portion 28 can be seen in the opening 29. However, since the shape of this bottom is not a feature point of this embodiment, the description thereof will be omitted.

In the superposition portion 23 in the present embodiment, as shown in FIG. 6, both the upper side 31 and the lower side 32 of the intermediate vertical rib 30 are curved rather than straight. Since the shape of the upper side of the intermediate vertical rib 30 and the vertical rib 26 are the same, the portion visible as the upper side of the vertical rib 26 in FIG. 6 shows the shape of the upper side 31 of the intermediate vertical rib 30 as it is. On the other hand, regarding the lower side, the lower side 33 of the vertical rib 26 is linear, but the lower side 32 of the intermediate vertical rib 30 is in a position protruding below it. Therefore, in FIG. 6, the lower side 32 of the intermediate vertical rib 30 is visible separately from the lower side 33 of the vertical rib 26.

As shown in FIG. 6, both the upper side 31 and the lower side 32 of the intermediate vertical rib 30 form an upwardly convex curve in the figure. Therefore, the shape of the intermediate vertical rib 30 is such that the upper side 31 has a convex curve shape and the lower side 32 has a concave curve shape. Further, although not shown in FIG. 6, the upper side and the lower side of the vertical rib 27 have the same shape as the upper side 31 and the lower side 32 of the intermediate vertical rib 30, respectively. Further, as can be seen from FIG. 3 and the like, the superposition portions 23 in the assembly fence 2 are located at both ends in the Y direction. The convex curve of the upper side 31 and the concave curve of the lower side 32 are arched at the superposed portions 23 at both ends.

As can be seen from FIGS. 4 and 5, the intermediate vertical rib 30 has a finite thickness. Therefore, although it is described above that the upper side 31 and the lower side 32 of the intermediate vertical rib 30 are curved, they are strictly curved surfaces. Further, since there are a plurality of intermediate vertical ribs 30, the upper side 31 (including the upper side of the vertical ribs 26 and 27) and the lower side 32 (including the lower side of the vertical rib 27) having the same shape are the overlapping portions 23, respectively. You can imagine a convex curved surface or a concave curved surface stretched on the ceiling surface or bottom surface.

Further, from the above, the lowest position of the superposition portion 23 is the positions 34 and 35 at both left and right ends in FIG. 6 on the lower side 32 of the intermediate vertical rib 30. This position corresponds to the lower sides of the above-mentioned vertical ribs 24 and 25 (FIGS. 4 and 5). The ground contact point when the assembly fence 2 is laid flat on a flat floor surface is at this position.

Further, as shown in FIG. 4, a convex portion 36 is provided on the upper surface side of the overlapping portion 23. The convex portion 36 also appears in FIG. The position where the convex portion 36 is provided is the position closest to the innermost side when viewed from the opening 29 in the superposed portion 23. The above-mentioned cylindrical portion 28 does not reach the position below the convex portion 36. Looking at the back view of FIG. 5, the position corresponding to the back surface of the convex portion 36 is the opening 37, and there is no cylindrical portion 28 inside the opening 37.

From this, in the state of the stacked body 7 shown in FIG. 3, the convex portion 36 of the assembly fence 2 of each stage except the uppermost stage is inserted into the opening 37 of the assembly fence 2 immediately above the convex portion 36. ing. However, the size of the convex portion 36 is set to have a considerable margin with respect to the opening 37. Therefore, it is not so much that the upper assembly fence 2 is positioned by fitting the convex portion 36 into the opening 37. Further, when the assembly fence 2 is placed flat inside out, the grounding point is the top of the convex portion 36.

Here, the relationship between the convex curved surface and the concave curved surface on the upper side 31 and the lower side 32 of the intermediate vertical rib 30 will be described. The curvature of the convex curved surface of the upper side 31 and the concave curved surface of the lower side 32 are actually different. More specifically, the concave curved surface of the lower side 32 is a gentler curved surface than the convex curved surface of the upper side 31. Therefore, as shown in the cross-sectional view of FIG. 7, when the overlapping portions 23 of the two assembly fences 2 are overlapped with each other, the convex curved surface (upper side 31) of the lower assembly fence 2 and the concave portion of the upper assembly fence 2 The curved surface (lower side 32) does not exactly match, but a gap is created between the two. The gaps are not uniform, and are larger toward both ends in the left-right direction in FIG. 7. And there is no gap at the center in the left-right direction. That is, the top of the convex curved surface and the bottom of the concave curved surface are in contact with each other.

In this embodiment, since the curvatures of the convex curved surface and the concave curved surface have the above-mentioned relationship, the stability of the stacked state shown in FIG. 7 is good. This will be described with reference to FIGS. 8 to 13. FIG. 8 shows a cross-sectional view of a situation in which the upper superimposing portion 23 is located and overlapped directly above the lower superimposing portion 23. However, in FIG. 8, the curvatures of the convex curved surface (upper side 31) and the concave curved surface (lower side 32) are emphasized more than they actually are. In the situation of FIG. 8, the centers of the convex curved surface (upper side 31) and the concave curved surface (lower side 32) are in contact with each other.

FIG. 9 shows a situation in which the upper superimposing portion 23 is slightly shifted to the right while the lower superimposing portion 23 is fixed with respect to the situation of FIG. In the state of FIG. 9, the contact point P1 between the convex curved surface (upper side 31) and the concave curved surface (lower side 32) is located at a position slightly shifted to the left from the center. The upper superimposing portion 23 in the state of FIG. 9 is slightly raised with respect to the upper superimposing portion 23 in FIG. The amount of increase is expressed as follows.
Rise width = (height difference between contact point P1 and center point P3)-(height difference between contact point P1 and center point P2) P2: center position of convex curved surface (upper side 31) P3: center position of concave curved surface (lower side 32)

That is, when the positional deviation in the left-right direction is small as shown in FIG. 9, the rising width of the upper superimposing portion 23 is also very small. This is because the rise of the upper superposition portion 23 is diminished by the difference in curvature between the convex curved surface and the concave curved surface.

FIG. 10 shows a situation in which the deviation is further increased from the situation in FIG. In the state of FIG. 10, the end point P4 of the concave curved surface (lower side 32) is a contact point between the convex curved surface (upper side 31) and the concave curved surface (lower side 32). In such a situation, the rising width of the upper superposition portion 23 is largely dominated by the shape of the convex curved surface (upper side 31). In other words, the above-mentioned reduction due to the difference in curvature is not very effective. Therefore, in the state of FIG. 10, the amount of increase is considerably larger than that of the situation shown in FIG.

What has been described with reference to FIGS. 8 to 10 will be considered for the entire assembly fence 2. In the stacking body 7 shown in FIG. 3, the situation where the stacking portions 23 are vertically overlapped with each other exists at both ends in the Y direction.

Here, consider a situation in which the dimensions of the upper and lower assembly fences 2 in the Y direction are slightly different due to individual differences or expansion and contraction over time. In this case, it is assumed that one of the left and right superposition points is correctly superposed as shown in FIG. Then, at the other superimposing point, the upper superimposing portion 23 and the lower superimposing portion 23 are inevitably displaced to the left and right. If the dimensional difference between the upper and lower assembly fences 2 is large, the deviation will be large as shown in FIG. 10 (or its left-right inversion). In this case, if the deviations are evenly distributed to the left and right overlapping points so that the entire assembly fence 2 is substantially symmetrical, both the left and right sides will be in the state shown in FIG. 9 (and their left-right inversion).

Considering the position of the center of gravity of the assembly fence 2 above, it is lower when both the left and right sides are in the state shown in FIG. 9 than when one is left in the state shown in FIG. This is because, as described above, the amount of increase in the state of FIG. 9 is very small, whereas the amount of increase in the state of FIG. 10 is quite large. Therefore, even if there is a certain dimensional difference between the upper and lower assembly fences 2, the stacked body 7 naturally tends to have a substantially symmetrical arrangement. Therefore, the stability of the stacked body 7 is extremely high. Further, the above-mentioned convex curved surface (upper side 31) and concave curved surface (lower side 32) are arched at the superposed portions 23 at both left and right ends, which also contributes to this stability. This is because even if the assembly fences 2 are slightly staggered and stacked, the upper assembly fence 2 does not tilt significantly unless the above-mentioned dimensional difference occurs.

Here, as a modification example, a case where the strength relationship of the curvature between the convex curved surface and the concave curved surface is reversed can be mentioned. Considering the situation corresponding to FIG. 8 in this case, FIG. 11 is obtained. That is, in FIG. 11, in the upper and lower superposition portions 123, the convex curved surface (upper side 131) is a gentler curved surface than the concave curved surface (lower side 132). In this case, as shown in FIG. 11, there are two points of contact between the two superposition portions 123.

In this case, the situations corresponding to the above-mentioned FIGS. 9 and 10 are shown in FIGS. 12 and 13. That is, in the case of this modification, if there is a positional deviation in the upper and lower superposition portions 123, the end portion of the upper concave curved surface (lower side 132) becomes a contact point regardless of the magnitude of the deviation. The rising width of the upper superposition portion 123 with respect to the state of FIG. 11 is determined only by the shape of the convex curved surface (upper side 131). There is no reduction due to the difference in curvature. Then, even when the deviation amount is small as shown in FIG. 12, there is a certain amount of increase. Further, even if the amount of deviation increases as shown in FIG. 13, the amount of increase does not increase much as compared with the case of FIG.

Consider the situation of the entire assembly fence in this case. When there is a dimensional difference between the upper and lower assembly fences, the position of the center of gravity of the upper assembly fence is as follows depending on the allocation between the left and right sides of the deviation. First, it is assumed that one of the superposition points is correctly superposed as shown in FIG. 11 and the other is in a state of being greatly displaced as shown in FIG. 13 (or its left-right inversion). In this case, the position of the center of gravity of the upper assembly fence is, of course, considerably higher than that in the case where there is no dimensional difference and both the left and right sides are as shown in FIG. However, even if the deviation is evenly distributed and the deviation is small as shown in FIG. 12 (and its left-right inversion) on both the left and right sides, the position of the center of gravity is still high to some extent. This is due to the above-mentioned increase. Therefore, in this modified example, there is a weak tendency for the stacked bodies to naturally have a substantially symmetrical arrangement.

However, this does not mean that the modified examples shown in FIGS. 11 to 13 cannot be used at all. Even in this modified example, the stability is much better than the case where the convex curved surfaces (or the concave curved surfaces) face each other between the upper and lower superposition portions. Further, the case where the convex curved surface and the concave curved surface have the same curvature may be considered in the same manner as the modified examples of FIGS. 11 to 13. Further, what has been described with reference to FIGS. 8 to 13 is the same even when the upper and lower assembly fences are all turned upside down and stacked. All of FIGS. 8 to 13 may be turned upside down.

Returning to the description of this embodiment. FIG. 14 is a cross-sectional view of the cut surface perpendicular to the X direction in FIG. 4 in a state where the overlapped portions 23 are overlapped with each other as in FIG. 7. However, the cutting position of the cross section is different between FIGS. 7 and 14. FIG. 7 is a cross-sectional view at a location where the intermediate vertical rib 30 is present, whereas FIG. 14 is a cross-sectional view at a location where the intermediate vertical rib 30 is not present. Note that FIG. 14 shows a situation in which the position between the convex curved surface (upper side 31) and the concave curved surface (lower side 32) in each superposition portion 23 is the hollow portion of the cylindrical portion 28. FIG. 15 is a cross-sectional view of the cut surface perpendicular to the Y direction. FIG. 15 shows a cross-sectional perspective view of the portion in the state of the stacked body 7 shown in FIG. FIG. 15 shows that the convex portion 36 of the lower assembly fence 2 is inserted into the opening 37 of the upper assembly fence 2.

The assembly fence 2 of this embodiment has the same shape even when rotated by 180 ° in a horizontal plane with respect to the posture shown in FIG. Therefore, when stacking as shown in FIG. 3, it is necessary to unify whether it is face up or inside out, but 180 ° rotation in the horizontal plane is arbitrary. This also applies to the modified examples shown in FIGS. 11 to 13.

[Second form]
16 and 17 show the assembly fence 4 according to the second embodiment. The difference between the assembly fence 4 of the present embodiment and the assembly fence 2 of the first embodiment described above lies in the details of the superposed portion. The points common to the assembly fence 2 will be omitted. In the assembly fence 4 of this embodiment, two types of superimposing portions 43 and superimposing portions 53 are arranged at diagonal positions, respectively. I wrote two types of superimposing part 43 and superimposing part 53, but these are actually related to the same shape turned upside down. Therefore, the superimposing portion 43 in FIG. 16 (bird's-eye view) and the superimposing portion 53 in FIG. 17 (top view) have the same shape. Naturally, the superimposing portion 53 in FIG. 16 and the superimposing portion 43 in FIG. 17 have the same shape.

The portion of region G in FIGS. 16 and 17 is enlarged and shown in FIGS. 18 and 19. One superposition portion 43 appears in both figures. The configuration of the superposition portion 43 is basically the same as that of the first embodiment with respect to the vertical ribs 44, 45, 46, 47, the cylindrical portion 48, the opening portion 49, and the intermediate vertical rib 50. The same applies to the convex curved surface of the vertical ribs 46 and 47, the upper side 51 of the intermediate vertical rib 50, and the concave curved surface of the lower side 52 as in the case of the first embodiment. The convex curved surface (upper side 51) and the concave curved surface (lower side 52) appear in FIGS. 20 to 22. On the other hand, the other type of superimposing portion 53 has a shape in which FIGS. 20 to 22 are turned upside down. Note that "52" appearing on the upper side in FIG. 20 is the lower side of the superposition portion 53 (upside down from the one on the front side) on the back side (upper right) in the X direction in FIG.

Therefore, in the assembly fence 4 of the present embodiment, as shown in FIG. 16, the superposition portion 43 with the convex curved surface (upper side 51) facing up and the superposition portion 43 with the concave curved surface (lower side 52) facing up are superposed. The portions 53 and the portions are arranged diagonally to each other. As a matter of course, when viewed from the perspective view of FIG. 17, a concave curved surface (lower side 52) is visible in the superposition portion 43, and a convex curved surface (upper side 51) is visible in the superposition portion 53. Therefore, when the assembly fence 4 is made into a stacking body 8 as shown in FIG. 23, the overlapping portions 43 are overlapped with each other as shown in FIGS. 21 and 22 at the two diagonal positions indicated by the arrows A. The orientation of the convex and concave curved surfaces is such that they are convex upward. On the other hand, in the remaining two locations indicated by the arrows B, the superposed portions 53 are superposed on each other. The state of the cross section here is an upside-down view of FIGS. 21 and 22.

Even in the case of this embodiment, as in the case of the first embodiment, the assembly fence 4 has the same shape even when rotated by 180 ° in the horizontal plane. Therefore, the assembly fence 4 of the present embodiment is also arbitrary with respect to 180 ° rotation in the horizontal plane when forming the stacking body 8. Of course, even in this embodiment, the stacked body 8 has high stability against misalignment.

The assembly fence 4 of the present embodiment has a higher degree of freedom in stacking than the assembly fence 2 of the first embodiment. This is because the assembly fence 4 has the same shape not only when it is rotated in a horizontal plane but also when it is rotated by 180 ° around the X axis in FIG. This is because when the assembly fence 4 is rotated in this way, the superposition portion 53 on the left end front side in the Y direction comes to the right end front side and is in the same direction as the original superposition portion 43. Of course, the superposition portion 43 on the front side of the right end comes to the front side of the left end and has the same orientation as the original superposition portion 53. The same goes for the back side. The same thing happens with a 180 ° rotation around the Y axis. That is, the assembly fence 4 of this embodiment can be stacked without worrying about whether it is face up or inside out. Therefore, in the assembly fence 4 of the present embodiment, it is sufficient to pay attention only to the distinction between the X direction and the Y direction when stacking the body 8.

In the superposition portion 43 and the superposition portion 53 in the assembly fence 4 of the present embodiment, the portions corresponding to the convex portions 36 and the openings 37 in the first embodiment have different shapes from those in the first embodiment. .. That is, the portion corresponding to the convex portion 36 is the convex portion 56 in FIG. 18 in this embodiment. The portion corresponding to the opening 37 is the recess 57 in FIG. 19 in this embodiment. The size of both the convex portion 56 and the concave portion 57 in the plate surface (XY plane) is smaller than that of the convex portion 36 and the opening portion 37 in the first embodiment. Further, it is arranged close to the end of the assembly fence 4. Further, it is not that they are arranged closest to the innermost side when viewed from the opening 49 in the superimposing portion 43 and the superimposing portion 53. The recess 57 is surrounded on three sides by auxiliary ribs 58.

The convex portion 56 also appears in FIG. The auxiliary rib 58 also appears in FIGS. 20 and 21. Note that "58" appearing on the upper side in FIG. 20 is an auxiliary rib in the superposition portion 53 on the back side (upper right) in the X direction in FIG. Further, "56" appearing on the lower side in FIG. 22 is a convex portion on the superimposing portion 53 on the back side. From the situation on the upper side in FIG. 20, it can be seen that the heights of the convex portion 56 and the auxiliary rib 58 are equal. The top of the convex portion 56 and the top of the auxiliary rib 58 are grounding points when the assembly fence 4 is laid flat on a flat floor surface.

24 to 26 show cross-sectional perspective views of the portion of the superposition portion 43 or the superposition portion 53 in the stacking body 8 of FIG. 23. FIG. 24 is a view of the cut surface at the same location as the figure shown as FIG. 15 in the first embodiment described above and the same line-of-sight direction. FIG. 25 is a view of a cut surface parallel to FIG. 24 but at a cut position slightly closer to the end. FIG. 25 shows that the convex portion 56 of the lower assembly fence 4 is inserted into the concave portion 57 of the upper assembly fence 4. Further, the position of the convex portion 56 in the X direction is within the range in which the cylindrical portion 48 exists, but the convex portion 56 of the lower assembly fence 4 and the cylindrical portion 48 of the upper assembly fence 4 still interfere with each other. I haven't. This is because the convex portion 56 is formed closer to the end portion and is located off the axis of the cylindrical portion 48. FIG. 26 is a diagram showing a situation of cutting in a vertical cross section parallel to the Y direction. The cutting position is a position where the convex portion 56 is located. FIG. 26 also shows a situation in which the convex portion 56 of the lower assembly fence 4 and the cylindrical portion 48 of the upper assembly fence 4 do not interfere with each other.

[Third form]
27 and 28 show the assembly fence 6 according to the third embodiment. The assembly fence 6 of this embodiment is based on the above-mentioned second embodiment, and the action of stabilizing the stacked body by the convex curved surface and the concave curved surface works not only in the Y direction but also in the X direction. Therefore, in the assembly fence 6 of the present embodiment, not only the superimposing portion 63 and the superimposing portion 73 are formed on both the frame portions 61 in the X direction, but also the superimposing portion 83 and the superimposing portion 83 are formed on both the frame portions 61 in the Y direction. The mating portion 93 is formed. The superimposing portion 63 and the superimposing portion 73 in the present embodiment are substantially the same as the superimposing portion 43 and the superimposing portion 53 in the second embodiment.

The portion of the region H in FIGS. 27 (bird's-eye view) and 28 (top view) is enlarged and shown in FIGS. 29 and 30. In both figures, one superimposing portion 63 and the adjoining superimposing portion 93 appear. The difference between the superposed portion 63 and the superposed portion 43 in the second form is that the vertical rib 64 is directly connected to the vertical rib 66 of the superposed portion 93.

The superposed portion 93 is formed with a convex curved surface 81 and a concave curved surface 82 in which the convex curved surface 71 and the concave curved surface 72 of the superposed portion 63 are turned upside down. Further, the convex portion 96 and the concave portion 97 are also formed in the superposed portion 93, but the vertical direction thereof is opposite to the convex portion 76 and the concave portion 77 of the superposed portion 63. The superposition portion 93 does not have a cylindrical portion 68, and therefore does not have an opening corresponding to the opening 69. As described above, in the assembly fence 6, when the corner portion is viewed from the outside (FIGS. 27 and 29), the convex curved surface 71 is formed on the right side and the concave curved surface 82 is formed on the left side. Looking up (FIGS. 28 and 30), the relationship between the left and right and the unevenness is reversed. This is the same in every corner of the four corners.

From this, even in the case of the present embodiment, as in the case of the second embodiment, the assembly fence 6 can be stacked without worrying about whether it is face up or inside out. Further, in this embodiment, the rotation of the assembly fence 6 in the horizontal plane during stacking has a higher degree of freedom than in the cases of the first and second embodiments described above. This is because the assembly fence 6 has the same shape even when rotated by 90 ° in the horizontal plane with respect to the arrangement of the convex curved surface and the concave curved surface of the superposed portion. In the case of 90 ° rotation (or 270 ° rotation), the directions of the cylindrical portion 68 and the opening 69 are not aligned, but this does not cause any particular problem in stacking.

A perspective view and a partially enlarged perspective view of the stacked body 9 in the case of this embodiment are shown in FIGS. 31 and 32. In the stacked body 9, the above-mentioned convex curved surface faces upward at the four points indicated by arrows C in FIG. 31. On the other hand, at the four points indicated by the arrows D, the convex curved surface faces downward. As a result, the stacked body 9 is highly stable against misalignment in both the X direction and the Y direction. In addition, the grounding points in the lowermost assembly fence 6 in the stacking body 9 of this embodiment are four convex portions 76 (and locations having the same shape) and four auxiliary ribs 79 (and locations having the same shape). There are 8 places.

In the assembly fence 4 in the second form and the assembly fence 6 in the third form, the curvatures of the convex curved surface (upper side 51) and the concave curved surface (lower side 52) are shown in the same manner as in the case of the first embodiment. The modified examples described with reference to FIGS. 11 to 13 can be applied. It is also possible to make the curvature of the convex surface and the concave surface the same.

As described in detail above, according to the present embodiment, the overlapping portions 23, 43, 53, 63, 73, 83, 93 are provided on the frame portions of the assembly fences 2, 4, and 6, and a plurality of overlapping portions are provided. The assembly fences can be stacked flat to form stacks 7-9. A convex curved surface and a concave curved surface are provided on the upper and lower surfaces of the superposed portion, and the convex curved surface enters the concave curved surface between the upper and lower assembly fences during stacking. This makes it difficult for the stacked bodies to collapse even if there is a slight dimensional difference between the assembly fences. In particular, by making the curvature of the convex curved surface steeper than the curvature of the concave curved surface, the stability of the stacked body can be further improved.

Further, in this embodiment, the above-mentioned superimposing portion is provided in the frame portion. The frame portion is also a place where the above-mentioned cylindrical portions 28, 48, 68 are provided. By concentrating the shapes related to the functions of the assembly fence (during flat stacking and assembling) on the frame portion in this way, the design portion 22 can be widely taken. Therefore, it is possible to make an assembly fence with high design. It does not mean that the frame part cannot be designed at all. Although there are some restrictions as compared with the design portion 22, the frame portion can also be used as a part of the design.

It should be noted that the present embodiment is merely an example and does not limit the present invention in any way. Therefore, as a matter of course, the present invention can be improved and modified in various ways without departing from the gist of the present invention. For example, the material of the assembly fence was not mentioned in particular, but synthetic resin, metal, wood, etc. may be used. However, synthetic resin is the easiest to apply.

Further, in the first embodiment, the convex curved surface and the concave curved surface are separately arched on the left and right at the superposition portion at both ends in the Y direction, but the present invention is not limited to this. Convex curved surfaces and concave curved surfaces may be connected to each other by the superposition portion at the left end and the superposition portion at the right end to form one virtual arch shape. Such a thing is inferior to the one of this embodiment in the stability of the stacked body, but it is much better than the one in which the convex curved surface vs. the convex curved surface or the concave curved surface vs. the concave curved surface face each other between the upper and lower assembly fences. Stability is obtained.

Further, in the third embodiment, the convex curved surface and the concave curved surface for the stability in the X direction and the convex curved surface and the concave curved surface for the stability in the Y direction are separately provided, but both are superposed. It may be provided concentrated on the part. The convex and concave curved surfaces themselves may also form a three-dimensional curved surface to provide stability in both directions. The overall shape of the assembly fence is almost square, but it is not limited to this and may be rectangular. However, if it is a rectangle, the degree of freedom of rotation in the horizontal plane during stacking is limited to every 180 ° even in the third case. Further, it is not essential that it is a rectangle, and it may be another polygonal shape.
