Description

[Technical Field]

[0001] The present invention relates to a slope that bridges a lower surface and a higher surface. [Background technology]

[0002] To facilitate movement over the step that occurs between a lower surface (low level surface) and an elevated surface (high level surface), a ramp is used to bridge the lower and higher surfaces.

[0003] For example, Japanese Patent Application Laid-Open No. 2017-133231 (Patent Document 1) discloses a slope member that is disposed adjacent to a step formed between a high surface and a low surface. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Application Laid-Open No. 2017-133231 Summary of the Invention [Problem to be solved by the invention]

[0005] However, the slope member disclosed in Patent Document 1 can accommodate a set height of steps, so the height of the steps must be known in advance in order to install the slope member. Therefore, if the height of the steps cannot be known in advance, it is necessary to investigate the height of the steps on site in advance, which is time-consuming. For this reason, it is desirable to realize a slope that can easily accommodate different heights without requiring a preliminary investigation, even if the height of the steps is not known in advance. [Means for solving the problem]

[0006] The slope according to the present invention comprises: A slope disposed adjacent to a step formed between a lower surface and a higher surface, bridging the lower surface and the higher surface, A plurality of divided bodies divided in the vertical direction and the front-rear direction; a connecting body that is separate from the divided bodies and connects the divided bodies together, Each of the plurality of divided bodies has a recess that can communicate with another divided body at abutting position with the other divided body, The connecting body is fitted across the recesses of the segments to be connected.

[0007] According to this configuration, the segments to be connected are connected by fitting a connector across the segments while the recesses of the segments are in communication with each other. Therefore, by connecting multiple segments to each other in the vertical and longitudinal directions, a slope bridging a low surface and a high surface can be appropriately formed. By adjusting the number and arrangement of the segments and connectors, steps of various heights can be accommodated. Therefore, prior on-site inspection is not required, and differences in height can be easily accommodated.

[0008] Preferred embodiments of the present invention will be described below, but the scope of the present invention is not limited to the preferred embodiments described below.

[0009] In one aspect, the recess has an opening portion that opens to the outer surface of the divided body, and a rear portion that is connected to a rear side of the opening portion and is formed wider than the opening portion, The connecting body preferably has enlarged portions at both ends that fit into the innermost portions of the segments to be connected.

[0010] With this configuration, the enlarged portion of the connector fits into the deep portion of the recess, preventing them from coming loose. By providing such a fitting structure at both ends of the connector, the segments to be connected can be properly connected to each other, and ultimately the entire slope can be properly formed.

[0011] In one embodiment, the divided body has: a slope member having a lower surface and an inclined surface inclined relative to the lower surface; a planar member having a first surface and a second surface disposed at an interval in the vertical direction relative to the first surface; The recess is formed on the lower surface and the first surface out of the lower surface, the inclined surface, the first surface, and the second surface.

[0012] According to this configuration, since no recesses are formed on the inclined surface of the inclined member, when forming a slope that is inclined as a whole, the surface can be made flat without any irregularities. Also, since no recesses are formed on the second surface of the planar member, by using the second surface as part of the surface of the slope, it is possible to form a slope that has, in addition to the inclined portion, portions with a different slope or shape from the inclined portion while keeping the surfaces of those slopes flat without any irregularities.

[0013] In one embodiment, the device further includes a spacer accommodated in the recess.

[0014] According to this configuration, when the movable body is positioned so as to overlap with the recessed portion in a vertical view, the spacer supports the weight of the movable body, thereby preventing the divided body from being deformed in the vertical direction due to the weight of the movable body.

[0015] Further features and advantages of the present invention will become more apparent from the following description of exemplary and non-limiting embodiments, which is given with reference to the drawings. [Brief explanation of the drawings]

[0016] [Figure 1] FIG. 1 is a perspective view showing a usage state of the slope of the first embodiment. [Figure 2] Side view of Figure 1 [Figure 3] FIG. 1 shows one aspect of connecting a ramp member to a planar member. [Figure 4] FIG. 2 shows a first example of use of the slope shown in FIG. 1; [Figure 5] FIG. 2 shows a second example of use of the slope shown in FIG. 1. [Figure 6] FIG. 10 is a perspective view showing a usage state of the slope of the second embodiment. DETAILED DESCRIPTION OF THE INVENTION

[0017] (Embodiment 1) A slope 1 of a first embodiment will be described with reference to the drawings. The slope 1 is disposed adjacent to a step 102 formed between a low level surface 100 and a high level surface 101 that is higher than the low level surface 100, and serves as a bridge between the low level surface 100 and the high level surface 101. Such a slope 1 makes it easy for a moving body 10, which moves using wheels, to move over the step 102 that occurs between the low level surface 100 and the high level surface 101. In this embodiment, a slope 1 is illustrated that allows a wheelchair, which is an example of the moving body 10, to easily move over the step 102. Note that the use of the slope 1 is not limited to wheelchairs. For example, the slope 1 may be used to allow a car to easily move over a step 102 that occurs between a parking space for a car and a road.

[0018] In this embodiment, the height direction of the step 102 between the lower surface 100 and the higher surface 101 is referred to as the "vertical direction H," the direction connecting the lower surface 100 and the higher surface 101 is referred to as the "front-rear direction D," and the direction perpendicular to both the vertical direction H and the front-rear direction D is referred to as the "width direction W." In the "front-rear direction D," the side closer to the lower surface 100 relative to the object described in the text is referred to as the "front side," and the side closer to the higher surface 101 is referred to as the "rear side." Also, for convenience of explanation, height refers to the height from the lower surface 100.

[0019] As shown in Figures 1 to 3, the slope 1 comprises partitions 2 divided in the up-down direction H and the front-to-back direction D, a connecting body 3 connecting the multiple partitions 2, and a spacer 4 attached to the partitions 2.

[0020] The multiple divided bodies 2 are aligned and butted against each other in the up-down direction H and the front-rear direction D, thereby forming a surface (surface 20) that bridges the lower surface 100 and the higher surface 101. The surface 20 is a surface on which the moving body 10 is placed, and is a surface that smoothly connects the lower surface 100 and the higher surface 101. Note that the surfaces 20 and the lower surface 100, and the surfaces 20 and the higher surface 101, do not have to be completely smoothly connected. For example, there may be a small step or gap between the lower surface 100 and the surface 20, and between the surface 20 and the higher surface 101, that does not hinder the moving body 10 from climbing over it.

[0021] In this embodiment, the divided body 2 has a solid structure except for the recessed portion 23 described below. A divided body 2 having such a structure allows the relatively heavy moving body 10 to be placed on the surface 20. The divided body 2 may also have a hollow structure. A divided body 2 having a hollow structure is light in weight, making it easy to transport to a site where there is a step 102.

[0022] The divided body 2 includes a slope member 21 and a planar member 22. The slope member 21 forms the surface 20. The planar member 22 adjusts the installation height of the slope member 21 or forms the surface 20. Preferably, the divided body 2 is composed of only two types of members, the slope member 21 and the planar member 22. This configuration is preferable because it reduces manufacturing costs by standardizing parts compared to when the divided body 2 is composed of multiple types of parts. Furthermore, because the slope 1 only has two types of parts that are relatively large in volume, the volume of parts that need to be transported to the site when installing the slope 1 at a site with a step 102 can be reduced.

[0023] As shown in FIGS. 2 and 3 , the slope member 21 has a lower surface 211, an inclined surface 212, a connecting surface 213, and a pair of side surfaces 214. The lower surface 211 includes a surface facing the low surface 100 or the planar member 22. The inclined surface 212 includes a surface inclined with respect to the lower surface 211. In this embodiment, the inclined surface 212 starts from the front end of the lower surface 211 and slopes obliquely upward toward the rear. The connecting surface 213 includes a surface connecting the lower surface 211 and the inclined surface 212. In this embodiment, the connecting surface 213 connects the rear end of the lower surface 211 and the rear end of the inclined surface 212. The pair of side surfaces 214 are surfaces facing outward in the width direction W and connect the lower surface 211, the inclined surface 212, and the connecting surface 213, respectively, on both sides of the width direction W.

[0024] The planar member 22 has a first surface 221, a second surface 222, a pair of third surfaces 223, and a pair of fourth surfaces 224. The first surface 221 includes a surface facing the lower surface 100 or the lower surface 211 of the sloped member 21. The second surface 222 is disposed at a distance from the first surface 221 in the up-down direction H. In this embodiment, the second surface 222 is a flat surface. The third surface 223 is a surface facing the step 102 or the connecting surface 213 of the sloped member 21. In this embodiment, the pair of third surfaces 223 are disposed at a distance from each other in the front-rear direction D. Furthermore, in this embodiment, one of the pair of third surfaces 223 connects the front end of the first surface 221 to the front end of the second surface 222, and the other of the pair of third surfaces 223 connects the rear end of the first surface 221 to the rear end of the second surface 222. The fourth surface 224 is a surface facing outward in the width direction W, and connects the first surface 221, the second surface 222, and the pair of third surfaces 223 on both sides in the width direction W, respectively.

[0025] As illustrated in FIGS. 1 and 2, the surface 20 is formed by arranging inclined surface members 21 and planar surface members 22 side by side in the up-down direction H and the front-rear direction D. In the example illustrated in FIGS. 1 and 2, the inclined surfaces 212 of the multiple inclined surface members 21 are arranged at different positions in the front-rear direction D and are smoothly connected to each other. The planar surface members 22 are arranged below the inclined surface members 21 so that the inclined surfaces 212 of the respective inclined surface members 21 are smoothly connected to each other. In other words, the planar surface members 22 serve to increase the installation height of the inclined surface members 21. In this embodiment, the number of planar surface members 22 arranged below the inclined surface members 21 increases by one toward the rear.

[0026] In this embodiment, the sloped surface member 21 is arranged so that the lower surface 211 faces downward. The planar member 22 is arranged so that the second surface 222 faces downward. In detail, in this embodiment, the planar members 22 are arranged in two tiers adjacent to the step 102, and the sloped surface member 21 is stacked on top of these planar members 22. The sloped surface member 21 is arranged so that the connecting surface 213 faces the step 102. One planar member 22 is arranged in front of the bottom planar member 22 of the two tiers of planar members 22. The sloped surface member 21 is arranged on top of this planar member 22. The sloped surface member 21 is arranged in front of this planar member 22.

[0027] The sloped surface member 21 and the planar surface member 22 are made of a hard material. Examples of hard materials include aluminum and other metal materials, thermoplastic resins, fiber-reinforced plastics, and wood. This configuration can suppress deformation of the sloped surface member 21 and the planar surface member 22 due to the weight of the moving body 10 when the moving body 10 is placed on the surface 20. Therefore, even when the moving body 10 is placed on the surface 20, it is easy to maintain a smooth connection between the surface 20 and the higher surface 101.

[0028] As shown in FIG. 2 , the recesses 23 are formed in the multiple segments 2 so that when the multiple segments 2 are arranged side by side in the up-down direction H and the front-rear direction D, the adjacent segments 2 can communicate with each other at their butt positions. The recesses 23 are depressions formed in the outer surfaces of the multiple segments 2. In this embodiment, the recesses 23 are formed on the lower surface 211 and the first surface 221 out of the lower surface 211, the inclined surface 212, the first surface 221, and the second surface 222. In the inclined surface member 21, the recesses 23 are formed on the lower surface 211 but not on the inclined surface 212. In this embodiment, in addition to the lower surface 211, the recesses 23 are also formed on the connecting surface 213. In addition, in the planar member 22, the recesses 23 are formed on the first surface 221 but not on the second surface 222. In this embodiment, in addition to the first surface 221, the recesses 23 are also formed on the third surface 223.

[0029] In this embodiment, when a plurality of segments 2 are assembled to form a slope 1, the recesses 23 of different segments 2 communicate with each other at the following three locations. The first portion P1 is the position where the lower surface 211 of the slope member 21 abuts against the first surface 221 of the planar member 22. The second portion P2 is the position where the connecting surface 213 of the slope member 21 abuts against the third surface 223 of the planar member 22. The third portion P3 is the position where the third surfaces 223 of two different planar members 22 abut against each other. Note that FIG. 2 shows one representative location each of the first portion P1, second portion P2, and third portion P3.

[0030] In this embodiment, as shown in FIG. 2 (see in particular the recess 23 arranged on the upper rear side), the recess 23 has an opening 231 and a rear portion 232. The opening 231 opens to the outer surface of the divider 2. The rear portion 232 communicates with the rear side of the opening 231. The rear portion 232 is formed wider than the opening 231. Note that "wide" generally means wide, regardless of the dimension in the width direction W. In this embodiment, the opening 231 is formed in a rectangular shape in cross section, and the rear portion 232 is formed in a circular shape in cross section.

[0031] The connector 3 is separate from the segments 2. The connector 3 fits across the recesses 23 of the segments 2 to be connected. In this embodiment, the connector 3 is formed in each of two different segments 2 and fits across both of the recesses 23 that communicate with each other. Specifically, as shown in FIGS. 1 to 3 , the connector 3 fits across the recesses 23 that communicate with each other in each of the first portion P1, the second portion P2, and the third portion P3. In this embodiment, the connector 3 connects the segments 2 in the second portion P2 and the third portion P3, so that the different segments 2 are connected so as not to be separated from each other in the front-rear direction D. Therefore, when the moving body 10 is placed on the surface 20, it is possible to prevent the different segments 2 from shifting in the front-rear direction D.

[0032] In this embodiment, as shown in FIG. 2 (particularly referring to the connecting body 3 arranged at the lower front side), the connecting body 3 has a bulging portion 31 and a connecting portion 32. The bulging portion 31 fits into the rear portion 232 of each of the segments 2 to be connected. The bulging portion 31 has a structure wider than the opening portion 231 of the recess 23. Therefore, the member constituting the opening portion 231 acts as a resistance against the bulging portion 31 fitted into the rear portion 232 slipping out of the rear portion 232 through the opening portion 231. The connecting portion 32 is a portion that connects the two bulging portions 31. The bulging portions 31 are formed at both ends of the connecting portion 32. When connecting the segments 2 to be connected, the connecting portion 32 is placed in the opening portion 231 of each of the segments 2 to be connected.

[0033] In this embodiment, as shown in FIG. 3 , the connector 3 has a uniform cross-sectional shape in the width direction W. Corresponding to the structure of this connector 3, the recesses 23 are provided along the width direction W and are open on at least one side in the width direction W. As illustrated in FIG. 3 , openings leading to the recesses 23 are formed in the side surface 214 of the sloped member 21 and the fourth surface 224 of the planar member 22. Therefore, the connector 3 can be inserted in the width direction W and fitted into the recesses 23 of the segments 2 to be connected, with the recesses 23 of the segments 2 communicating with each other. Therefore, there is no need to deform the segments 2 to fit the connector 3 into the recesses 23, which facilitates the work of connecting multiple segments 2.

[0034] 3, openings for the recesses 23 are formed on both of the pair of fourth surfaces 224. Similarly, openings for the recesses 23 are formed on both of the pair of side surfaces 214 of the inclined surface member 21. With this configuration, the connecting body 3 can be inserted into the segments 2 to be connected from either side in the width direction W and fitted into the recesses 23. Therefore, the insertion direction is less likely to be restricted by the surrounding conditions of the installation location, making the work of connecting multiple segments 2 even easier.

[0035] Preferably, the connector 3 is made of a hard material. With such a configuration, the expanded portion 31 of the connector 3 can function as a structural member that supports the weight of the moving body 10.

[0036] The spacer 4 is housed in the recess 23. More specifically, the spacer 4 is housed in a recess 23 that does not contribute to the connection of the multiple connecting bodies 3. Specifically, the spacer 4 is housed in a recess 23 that does not communicate with other recesses 23 when the multiple divided bodies 2 are assembled. In this way, the spacer 4 housed in the recess 23 that does not contribute to the connection can support the weight of the moving body 10 placed on the surface 20.

[0037] In this embodiment, the spacer 4 is formed in a shape obtained by dividing the connector 3 in half (more specifically, by dividing it in half at a midpoint in the direction connecting the two swollen portions 31). The spacer 4 has a circular shape that is wider than the opening portion 231 in a cross-sectional view. This prevents the spacer 4 housed in the recess 23 from passing through the opening portion 231 and slipping out of the recess 23. In this embodiment, the spacer 4 has a uniform cross-sectional shape. The spacer 4 having such a shape is inserted and housed in the recess 23, for example, along the width direction W through an opening of the recess 23 formed on the side surface 214 of the slope member 21 or the fourth surface 224 of the planar member 22.

[0038] The connector 3 and the spacer 4 may be pressed from the up-down direction H or the front-rear direction D to widen the opening 231 , and then housed in the recess 23 through the widened opening 231 .

[0039] In this embodiment, the spacer 4 has a solid structure. Preferably, the spacer 4 is made of the hard material described above. With this configuration, the spacer 4 can support the weight of the moving body 10 well.

[0040] According to the slope 1 of the present embodiment described above, the segments 2 to be connected are connected by connecting the recesses 23 of the segments 2 to be connected and fitting the connector 3 across them. Thus, by connecting multiple segments 2 to each other in the up-down direction H and the front-to-back direction D, it is possible to appropriately form a slope 1 that bridges a low surface 100 and a high surface 101. In this case, by adjusting the number and arrangement of the segments 2 and connectors 3, it is possible to accommodate steps 102 of various heights. Therefore, there is no need for a prior on-site survey, and differences in height can be easily accommodated.

[0041] Furthermore, with the slope 1 of this embodiment, the positions of the segments 2 and the connecting members 3 can be changed simply by inserting and fitting the connecting members 3 into the recesses 23. Therefore, the slope 1 of this embodiment can be adjusted more easily than when a connecting member 3 structure that cannot be separated once connected is adopted. In addition, the slope 1 of this embodiment connects multiple segments 2 using connecting members 3 that are separate from the segments 2, so there is no structure that protrudes outward. Therefore, the slope 1 of this embodiment does not have a protruding structure that is unsuitable as a structure for supporting weight, positioned in a position that supports weight. Furthermore, with the slope 1 of this embodiment, the protruding structure is positioned on the path along which the moving body 10 passes, so the movement of the moving body 10 is not obstructed by the protruding structure.

[0042] (First use case) A first example of use of the slope 1 will be described with reference to Fig. 4. This example shows an example in which the height of the slope 1 is adjusted to a step 102 that is lower than the step 102 shown in Figs. 1 to 3. In the following explanation, explanations that overlap with the contents explained above will be omitted.

[0043] The height of the step 102 shown in FIG. 4 is approximately the height of one inclined surface member 21 stacked on top of one planar surface member 22. Therefore, one planar surface member 22 is placed in a position adjacent to the step 102. An inclined surface member 21 is placed on top of this planar surface member 22. In front of the planar surface member 22, another inclined surface member 21 is placed in addition to the inclined surface member 21 placed adjacent to the step 102. In other words, the surface 20 is formed by the inclined surface member 21 placed in a position adjacent to the step 102 and the inclined surface member 21 placed in front of the planar surface member 22. In this first usage example, the entire surface 20 of the slope 1 is formed to be a flat, inclined surface without any irregularities.

[0044] (Second use case) A second use example of the slope 1 will be described with reference to Fig. 5. In this use example, the slope 1 having a flat surface as the surface 20 other than the inclined surface 212 is placed on the step 102 having the same height as the step 102 shown in Fig. 4.

[0045] The surface 20 of the slope 1 illustrated in FIG. 5 is formed so that the position adjacent to the step 102 is a horizontal plane. To achieve this, planar members 22 are arranged in two layers at the position adjacent to the step 102. Of the two layered planar members 22, the lower planar member 22 is arranged so that its second surface 222 abuts the lower surface 100. The upper planar member 22 of the two layered planar members 22 is oriented opposite to the lower planar member 22, and its first surface 221 abuts the first surface 221 of the lower planar member 22. As a result, the second surface 222 of the upper planar member 22 is positioned on the upper side. Therefore, the second surface 222 becomes part of the surface 20. The recess 23 formed in the first surface 221 of the lower planar member 22 is connected to the recess 23 formed in the first surface 221 of the upper planar member 22. This allows the connector 3 to connect the planar member 22 arranged on the upper side to the planar member 22 arranged on the lower side.

[0046] In front of the two-tiered planar members 22, a planar member 22 and an inclined surface member 21 placed on this planar member 22, and the inclined surface member 21 are arranged in the order shown facing forward. In this second example of use, the surface 20 of the slope 1 is formed so as to be a combination of a flat, inclined surface without any irregularities and a flat, horizontal surface without any irregularities.

[0047] (Embodiment 2) The slope 1 of the second embodiment will be described with reference to Fig. 6. The slope 1 of the second embodiment differs from the slope 1 of the first embodiment in that the dimension in the width direction W can be adjusted. Hereinafter, the differences between the slope 1 of the second embodiment and the slope 1 of the first embodiment will be mainly described.

[0048] The multiple segments 2 are arranged along the width direction W. In this case, the recess 23 of one segment 2 is formed so that it can communicate with the recess 23 of another segment 2 that is arranged adjacently at a different position in the width direction W. The dimension L1 of the connecting member 3 in the width direction W is larger than the dimension of one segment 2 in the width direction W. With this configuration, the connecting member 3 can connect segments 2 that are arranged at different positions in the width direction W. Therefore, the dimension of the slope 1 in the width direction W is adjustable. Furthermore, because no structure or parts other than the connecting member 3 are required to connect segments 2 that are arranged at different positions in the width direction W, the number of types of parts required to form the slope 1 can be reduced.

[0049] In this embodiment, the recess 23 of the division 2 arranged on the left side (one side in the width direction W) is connected to the recess 23 of the division 2 arranged on the right side (the other side in the width direction W). Therefore, by fitting the connector 3 across the recess 23 of the division 2 arranged on the left side and the recess 23 of the division 2 arranged on the right side, the division 2 arranged on the right side is connected to the division 2 arranged on the right side. Here, if the dimension L1 of the connector 3 in the width direction W is larger than the dimension L2, which is the sum of the dimension in the width direction W of the division 2 arranged on the left side and the dimension in the width direction W of the division 2 arranged on the right side, a portion of the connector 3 protrudes from the division 2 arranged on the left or right side. However, because the cross section of the connector 3 is smaller than that of the division 2, it can be easily cut even at a site where a step 102 is provided. Therefore, as shown in FIG. 6 , the portion of the connector 3 protruding from the division 2 is cut off. This prevents a protruding structure from being located in a position that will be a path through which the moving body 10 passes.

[0050] In this embodiment, similar to the connecting body 3, the spacer 4 is also accommodated across the recess 23 of the division body 2 arranged on the left side and the recess 23 of the division body 2 arranged on the right side. If the dimension of the spacer 4 in the width direction W is larger than the dimension of the width direction W of the division bodies 2 arranged in the width direction W, the portion protruding from the division body 2 is cut off.

[0051] Other Embodiments (1) In the first embodiment, the divided body 2 is described as including the sloped member 21 and the planar member 22. However, the divided body 2 is not limited to only the sloped member 21 and the planar member 22, and may include other members.

[0052] (2) In the first embodiment, the inclined surface member 21 and the planar surface member 22 are described as being made of a hard material. However, the inclined surface member 21 and the planar surface member 22 may be made of a soft material. Examples of soft materials include rubber and elastomer. With this configuration, even if the moving body 10 makes impact contact with the surface 20, the impact caused by the contact of the moving body 10 can be mitigated. Furthermore, the members arranged on the lower step can be made of a hard material, and the members arranged on the upper step can be made of a soft material. In this way, the weight of the moving body 10 can be supported, and the impact can be mitigated when the moving body 10 makes impact contact with the surface 20.

[0053] In addition, the surface 20 is preferably made of a material or structure that prevents the movable body 10 from slipping. Examples of materials that prevent the movable body 10 from slipping include rubber, and examples of structures that prevent the movable body 10 from slipping include unevenness provided on all or part of the surface 20. This configuration prevents the movable body 10 from slipping on the surface 20. Furthermore, it is also preferable that the surfaces of one divided body 2 other than the surfaces that make up the surface 20, i.e., the surfaces that contact other divided bodies 2, the surfaces that contact the lower surface 100, and the surfaces that contact the step 102, are also made of a material or structure that prevents slipping, similar to the above. This configuration prevents misalignment between one divided body 2 and another divided body 2 adjacent to the divided body 2, between the divided body 2 and the lower surface 100, and between the divided body 2 and the step 102.

[0054] (3) In the first embodiment, the recesses 23 are not formed on the second surface 222 of the planar member 22. However, the recesses 23 may be formed on the second surface 222 of the planar member 22.

[0055] (4) In the first embodiment, a single connector 3 is used to connect the segments 2 to be connected. However, the segments 2 may be connected using multiple connectors 3 each having a length in the width direction W that is shorter than that of the segments 2.

[0056] (5) In the first embodiment, it has been described that the inclined surface 212 and the second surface 222 form the surface 20. However, it is also possible to arrange a separate member such as non-slip rubber on the inclined surface 212 or the second surface 222, and form the surface 20 using the separate member.

[0057] (6) In the second use example of the first embodiment, the case where the surface 20 at a position adjacent to the step 102 is formed by the second surface 222 has been described as an example. However, the planar member 22 and the inclined surface member 21 may be arranged so that the second surface 222 is arranged at a position other than the position adjacent to the step 102. For example, the inclined surface member 21 and the planar member 22 may be arranged so that the surface 20 is formed by the inclined surface 212, the second surface 222, and the inclined surface 212 in the stated order.

[0058] (7) In the first embodiment, the second surface 222 of the planar member 22 is described as being flat. However, the second surface 222 is not limited to being flat as long as the planar member 22 can be stably placed on the lower surface 211. For example, the second surface 222 may be a surface having a slight curved or bent portion.

[0059] (8) In the second embodiment, two divided bodies 2 are arranged adjacent to each other in the width direction W, and the recesses 23 thereof are connected to each other. However, three or more divided bodies 2 may be arranged adjacent to each other in the width direction W, and all of the recesses 23 thereof may be connected to each other. With such a configuration, the number of types of parts required to form a large slope 1 in the width direction W can be reduced.

[0060] (9) The configurations disclosed in the above-described embodiments (including the above-described embodiments and other embodiments; the same applies hereinafter) can be applied in combination with configurations disclosed in other embodiments, as long as no contradiction occurs. Regarding other configurations, the embodiments disclosed in this specification are illustrative in all respects and can be appropriately modified within the scope of the present disclosure.
