[0005] The present invention has been made in consideration of the above-mentioned problems, and has an object to provide a slope device whose height is fixed. [Means for solving the problem]

[0006] The slope device of the present invention is characterized by comprising a slope portion disposed at an angle, and a support portion that supports the slope portion in a fixed height direction. Effect of the Invention

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0009] The slope device according to this embodiment will be described below with reference to the drawings. For ease of explanation, in each drawing, the upper side is indicated as Up, the lower side as Lo, the right side as R, the left side as L, the front side as Fr, and the rear side as Rr, as necessary.

FIG. 2(b) is a rear view showing an example of the configuration of the slope device 100. FIG. 3 is a side view showing an example of the configuration of the slope device 100. FIG. 4(a) is a side view showing a part of the configuration of the slope device 100. FIG. 4(b) is a rear view showing a part of the configuration of the slope device 100. FIG. 5 is a bottom view showing an example of the configuration of the slope device 100. FIG. 6 is a side view of the slope device 100 when installed on a double floor surface. The slope device 100 includes a slope portion 110, a support portion 120, an anti-slip portion 130, and a linear portion 140.

[0011] The slope section 110 is disposed at an incline and has the function of allowing people and objects to pass over a step at a gentle gradient. The slope section 110 has a substantially rectangular shape when viewed from above. The slope section 110 is supported by support sections 120 disposed at the rear ends of the slope section 110, respectively at both ends in the left and right directions.

[0012] The slope portion 110 has a length in the front-rear direction of, for example, 800 mm to 1200 mm, and a length in the left-right direction of, for example, 400 mm to 800 mm. The slope portion 110 has a first slope portion 111, a second slope portion 112, and a main slope portion 113. The slope portion 110 is arranged in the order of the first slope portion 111, the second slope portion 112, and the main slope portion 113 from the front side to the rear side. The surfaces (upper surfaces) of the first slope portion 111, the second slope portion 112, and the main slope portion 113 are each the same color, for example, silver. The slope portion 110 has a ridge on the surface thereof that is integrally formed in the left-right direction as an anti-slip protrusion. The ridge has a substantially sawtooth shape when viewed from the side.

[0013] The first slope portion 111 is in contact with the lower step of the step and forms an inclined surface continuing from the lower step. The first slope portion 111 is located in front of the second slope portion 112. The first slope portion 111 is, for example, in the shape of a generally flat plate whose left-right length is longer than its front-to-back length, and is configured as a single piece. The first slope portion 111 is made of, for example, an aluminum alloy, and is formed by extrusion molding.

[0014] The first slope portion 111 also has a seat portion 1112 that comes into contact with the lower step of the step. The seat portion 1112 is formed across the left-right direction of the first slope portion 111. In this embodiment, the seat portion 1112 is formed integrally with the first slope portion 111 by extrusion molding, but it may also be formed by combining separate members. The seat portion 1112 also has a plurality of holes 1113 for fixing to the lower step of the step using anchor bolts or the like.

[0015] The first slope portion 111 has a rotated portion 1111 at its rear end. The rotated portion 1111 fits into a rotating portion 1121 (described later) of the second slope portion 112, and rotates relative to the second slope portion 112. That is, the first slope portion 111 can rotate about an axis along the left-right direction of the rotating portion 1121 relative to the second slope portion 112. When the rotating portion 1121 and the rotated portion 1111 exceed a certain rotation range, they come into contact with each other and the rotation is restricted. In this embodiment, the rotated portion 1111 is formed integrally with the first slope portion 111 by extrusion molding, but separate members may be combined.

[0016] The second slope portion 112 constitutes an inclined surface continuing from the first slope portion 111. The second slope portion 112 is connected to the main slope portion 113. The second slope portion 112 is located between the first slope portion 111 and the main slope portion 113. The second slope portion 112 is, for example, a substantially flat plate whose length in the left-right direction is longer than its length in the front-rear direction, and is configured as a single piece. The second slope portion 112 is made of, for example, an aluminum alloy, and is formed by extrusion molding.

[0017] The second slope portion 112 has a rotated portion 1122 at its rear end. The rotated portion 1122 fits into a rotating portion 1135 (described later) of the main slope portion 113, and rotates relative to the main slope portion 113. That is, the second slope portion 112 can rotate about an axis along the left-right direction of the rotating portion 1135 relative to the main slope portion 113. When the rotated portion 1122 and the rotating portion 1135 exceed a certain rotation range, they come into contact with each other and the rotation is restricted. In this embodiment, the rotated portion 1122 is formed integrally with the second slope portion 112 by extrusion molding, but separate members may be combined.

[0018] The second slope portion 112 has a rotating portion 1121 at the front end. As described above, the rotating portion 1121 fits into the rotated portion 1111 and rotates relative to the first slope portion 111. The rotating portion 1121 and the rotated portion 1111 come into contact with each other and the rotation is restricted when they exceed a certain rotation range. In this embodiment, the rotating portion 1121 is formed integrally with the second slope portion 112 by extrusion molding, but separate members may be combined.

[0019] The second slope portion 112 has angle members 1123 at both left and right ends. The angle members 1123 function as stoppers that prevent the second slope portion 112 and the first slope portion 111 or the main slope portion 113 from sliding relative to each other. The rotating part 1121 and the rotated part 1111, and the rotating part 1135 and the rotated part 1122, are fitted together and do not separate in the front-rear direction, but they do slide relative to each other in the left-right direction. To prevent this from happening, angle members 1123 are placed on both left-right ends of the second slope part 112 as stoppers.

[0020] The angle member 1123 is L-shaped and made of an aluminum alloy, and is joined to the second slope portion 112 by screws, rivets, etc., but may be made of other materials or may be joined by other methods.

[0021] The angle member 1123 is colored in a color, for example, red, different from the surfaces of the first slope portion 111, the second slope portion 112, and the main slope portion 113. This allows the angle member 1123 to function as a visual recognition portion for recognizing the end of the slope portion 110. The coloring includes coloring by surface treatment such as anodizing, coloring by applying paint, coloring by attaching a sticker or the like, coloring by mixing a coloring agent, and the like. In this embodiment, the angle member 1123 is L-shaped, but it may be a plate member covering the side surface of the end of the second slope portion 112, or it may be a plate member covering the surface of the end of the second slope portion 112.

[0022] The main slope portion 113 constitutes an inclined surface continuing from the second slope portion 112. The main slope portion 113 is located on the rear side of the second slope portion 112. The main slope portion 113 has a main body portion 1131, a rail member 1132, and an angle member 1133.

[0023] The main body 1131 is a base for integrally connecting other members constituting the main slope section 113. As shown in FIG. 3, the main body 1131 is substantially U-shaped at both front and rear ends, and is substantially groove-shaped with an opening in the downward direction. Note that the angle members 1123 and 1133 are omitted in FIG. 3. The main body 1131 joins a plurality of rail members 1132 so as to enclose them from the front and rear with portions each formed in a substantially U-shape. The second slope section 112 is connected to the front side of the main body 1131. In addition, the angle members 1133 are joined to both left and right ends of the main body 1131. The surface (upper surface) of the main body 1131 is, for example, silver colored.

[0024] The main body 1131 is, for example, substantially flat with a left-right length longer than a front-to-back length. The main body 1131 is configured by arranging a plurality of plate-like members in parallel from front to back with no gaps. The plurality of plate-like members that configure the main body 1131 are, for example, made of an aluminum alloy and formed by extrusion molding.

[0025] The main body 1131 has a rotating part 1135 at the front end. As described above, the rotating part 1135 fits into the rotated part 1122 and rotates relative to the rotated part 1122. That is, the main slope part 113 can rotate about an axis along the left-right direction of the rotating part 1135 relative to the second slope part 112. When the rotating part 1135 and the rotated part 1122 exceed a certain rotation range, they come into contact with each other and the rotation is restricted. In this embodiment, the rotating part 1135 is formed integrally with the main body 1131 by extrusion molding, but it may be combined with separate members.

[0026] The rail members 1132 are members that support the main body portion 1131 and thereby transmit the load applied to the main slope portion 113 to the entire slope portion 110 or the support portion 120. As shown in FIG. 2(b) and FIG. 5, the rail members 1132 include rail members 1132a disposed at both the left and right ends of the main slope portion 113 and rail member 1132b disposed therebetween. The rail members 1132a and 1132b are joined so as to be wrapped around the main body portion 1131. In this embodiment, two rail members 1132a and three rail members 1132b are joined to the main body portion 1131, but any other number may be used.

[0027] The beam member 1132a is disposed along the front-rear direction at both left-right ends of the main slope section 113. The beam member 1132a is elongated in the front-rear direction. Specifically, as shown in FIG. 2(b), the beam member 1132a is hollow and has a substantially rectangular shape with a closed cross section and has ribs inside. The beam member 1132a is also substantially rectangular when viewed from the side. The width of the beam member 1132a in the left-right direction is wider than that of the beam member 1132b. The beam members 1132b are disposed along the front-rear direction at intervals in the center of the left-right direction of the main slope section 113. The beam members 1132b are elongated in the front-rear direction. Specifically, as shown in FIG. 2(b), the beam members 1132b are hollow and have a substantially rectangular shape with a closed cross section, and have a pair of protrusions 1134 protruding toward the floor surface from two vertices on the substantially floor surface side. The pair of protrusions 1134 can improve the strength of the beam member 1132b. The pair of protrusions 1134 are located in a portion of the beam member 1132b excluding the front and rear ends, i.e., in the substantially center of the front-rear direction, as viewed from the side. Therefore, as shown in FIG. 3, the distance l1 of the beam member 1132b from the substantially center as viewed from the side is longer than the distance l2 of the front or rear ends. By configuring the beam member 1132b in this manner, it is possible to improve the strength of the slope portion 110 while suppressing interference with the protrusion portion 1134 when the main body portion 1131 encloses the beam member 1132b from the front and rear.

[0028] The support portion 120 is disposed below the slope portion 110, and supports the slope portion 110 in an inclined state, thereby providing a gentle gradient. The support portion 120 does not have a function of adjusting the height of the slope portion 110, and supports the slope portion 110 in a state in which the height direction is fixed. That is, the support portion 120 supports the slope portion 110 at a predetermined height. Specifically, the support portion 120 supports the slope portion 110 so that the height of the slope portion 110 is in the range of approximately 20 mm or more and approximately 100 mm or less. Here, the height of the slope portion 110 refers to the distance from the floor surface to the part of the slope portion 110 that is furthest away in the vertical direction. The support portion 120 of this embodiment supports the slope portion 110 so that the height of the slope portion 110 is approximately 80 mm. The length of the slope portion 110 in the front-rear direction is set so that the gradient of the slope portion 110 is expressed as the height of the slope portion 110 divided by the length of the slope portion 110 in the front-rear direction, and is less than 1 / 6 and more than 1 / 12. The gradient of the slope portion 110 is specified in this manner in consideration of the "Enforcement Order of the Parking Lot Law," "Law Concerning Promotion of Smooth Movement of the Elderly, Disabled, etc.", and if the gradient was within a range outside of this range, the slope device 100 would become large and the gradient would become too steep.

[0029] The support portion 120 of this embodiment has support portions 120L and 120R. The support portion 120L is disposed at the rear end and left end below the slope portion 110, and the support portion 120R is disposed at the rear end and right end below the slope portion 110. The support portions 120L and 120R have the same basic configuration. Therefore, the following mainly describes the support portion 120L, and the description of the support portion 120R is omitted as appropriate.

[0030] The support portion 120L has an attachment portion 121 and a ground portion 122. The mounting portion 121 is a portion to which the grounding portion 122 is fixed and which mounts the grounding portion 122 to the slope portion 110. As shown in FIG. 4, the mounting portion 121 has a substantially hat-shaped cross section when viewed from the back (rear side) and a substantially trapezoidal cross section when viewed from the side. The mounting portion 121 is an integral member formed by bending through press molding, and is made of, for example, iron, but may be made of other materials. The mounting portion 121 has a hole on the surface in contact with the grounding portion 122 for mounting to the main slope portion 113. The mounting portion 121 is attached to the slope portion 110 through the hole using a screw, rivet, or the like, but may be attached by other methods.

[0031] The grounding portion 122 comes into contact with the floor surface and supports the slope portion 110 via the mounting portion 121. The grounding portion 122 also generates friction between the floor surface and the slope device 100, making it difficult for the slope device 100 to move when an external force is applied. The grounding portion 122 is made of, for example, a soft synthetic resin.

[0032] 4 and 5, grounding portion 122 is generally L-shaped when viewed from the back, side, and bottom. Grounding portion 122 has holes on the surface that contacts the floor for fixing to mounting portion 121. Grounding portion 122 is fixed to mounting portion 121 through the holes using screws, rivets, or the like. The grounding portion 122 protrudes toward the floor surface and has protrusions 1221 and 1222 that come into contact with the floor surface. Here, the protrusions 1221 and 1222 are formed in different directions and are different types. As shown in Fig. 4, the protrusions 1221 are disposed on the outer side in the left-right direction of the grounding portion 122 (see also Fig. 5). The protrusions 1221 are convex stripes along the front-rear direction, and are formed in approximately the same shape along the front-rear direction. A plurality of the protrusions 1221 (three in this example) are formed at intervals in the left-right direction, and are saw-tooth shaped when viewed from the rear. The protrusions 1221 protrude obliquely so as to extend outward in the left-right direction as they approach the floor surface.

[0033] As shown in the enlarged view of FIG. 4(b), the angle of the protrusion 1221 between the side surface on one side and the floor surface is α1, and the angle of the outer side in the left-right direction is β1. The angle α1 is smaller than the angle β1. Therefore, when the grounding part 122 is in contact with the floor surface, the grounding part 122 is difficult to move toward the outside in the left-right direction. The protrusion 1221 of the grounding part 122 of the support part 120L and the protrusion 1221 of the grounding part 122 of the support part 120R are symmetrical with respect to the left-right center line of the slope device 100. Therefore, since the grounding part 122 of the support part 120L and the grounding part 122 of the support part 120R are difficult to move toward opposite directions in the left-right direction, it is possible to suppress the slope device 100 from shifting in either the left or right direction due to vibrations or the like when a person or object passes by. The protrusion 1221 is not limited to being disposed on a part of the grounding portion 122, but may be disposed over the entire surface that contacts the floor surface.

[0034] On the other hand, as shown in FIG. 4, the protrusion 1222 is disposed on the center side of the grounding part 122 in the left-right direction (see also FIG. 5). The protrusion 1222 is a convex strip along the left-right direction, and is formed in approximately the same shape across the left-right direction. A plurality of protrusions 1222 (12 in this example) are formed at intervals in the front-rear direction, and are saw-tooth shaped when viewed from the side. In FIG. 4(a), two of the plurality of protrusions 1222 reach the left end of the grounding part 122 and are therefore visible, but the other protrusions 1222 do not reach the left end and are therefore not visible. The protrusions 1222 protrude obliquely so as to extend forward as they approach the floor surface.

[0035] As shown in the enlarged view of FIG. 4(a), the protrusion 1222 has an angle between the side surface on one side (rear side) and the floor surface, where the angle on the rear side is α2 and the angle on the front side is β2, and the angle α2 is smaller than the angle β2. Therefore, when the grounding part 122 is in contact with the floor surface, the grounding part 122 is difficult to move toward the front side. Therefore, it is possible to prevent the slope device 100 from moving forward and creating a gap between the slope part 110 and the upper step of the step. Note that the protrusion 1222 is not limited to being disposed on a part of the grounding part 122, but may be disposed over the entire surface in contact with the floor surface. In addition, the protrusion 1222 of the grounding part 122 of the support part 120L and the protrusion 1222 of the grounding part 122 of the support part 120R protrude obliquely in the same direction.

[0036] The anti-slip portion 130 is disposed between the slope portion 110 and the floor surface. The anti-slip portion 130 generates friction between the slope portion 110 and the floor surface, thereby making it difficult for the slope device 100 to move when an external force is applied. 5, anti-slip portion 130 has anti-slip portion 130a which is long in the left-right direction and anti-slip portion 130b which is long in the front-rear direction. A plurality of anti-slip portions 130a (three in this example) are arranged at intervals in the left-right direction on the rear surface of first slope portion 111 of slope portion 110. A plurality of anti-slip portions 130b (three in this example) are arranged at intervals in the left-right direction on the rear surface of second slope portion 112 of slope portion 110. Anti-slip portions 130a and 130b are substantially rectangular when viewed from below.

[0037] The linear portion 140 functions as a visual recognition portion for recognizing the boundary between the slope portion 110 and the step. The linear portion 140 is, for example, a plate-shaped member, and is disposed at the rear end of the main slope portion 113 and fixed by screws, rivets, or the like. The linear portion 140 is colored in a color different from the surfaces of the first slope portion 111, the second slope portion 112, and the main slope portion 113, for example, in pink. The linear portion 140 may be the same color as the angle member 1133 or may be a different color. The coloring includes coloring by surface treatment such as anodizing, coloring by applying paint, coloring by attaching a sticker or the like, coloring by mixing a coloring agent, and the like. In this embodiment, the linear portion 140 is colored by applying paint, but the linear portion 140 may be, for example, a plate-shaped member different from the main body portion 1131 of the main slope portion 113 and fixed to the main body portion 1131 by screws, rivets, or the like.

[0038] A method for installing the slope apparatus 100 configured as above at a work site having steps will be described with reference to FIG. FIG. 6 is a side view showing an example of a work site with a step between a room and a corridor (at the boundary). A room is an office, a living space, or the like, and is a space partitioned by a floor of a building. A corridor is a passageway that connects rooms together or connects a room to an entrance of a floor. As shown in FIG. 6, a floor has a floor surface 151 on the room side and a floor surface 152 on the corridor side, for example, as a reinforced concrete structure. The floor surface 152 on the corridor side corresponds to an example of a first step. In general, in a building where people perform office work or live, the floor surface 151 on the room side is lower than the floor surface 152 on the corridor side, and there is a step between the room and the corridor. The reason why the floor surface 151 on the room side is lower than the floor surface 152 on the corridor side is because it is assumed that a double floor 153 will be installed on the floor surface 151 on the room side, as shown in FIG. 6. The double floor 153 corresponds to an example of a second step. The double floor 153 is installed so as to overlap the upper side of the room-side floor surface 151 with a space therebetween. By installing the double floor 153, communication / power cables and various piping can be arranged in the space between the room-side floor surface 151 and the floor surface panel 1531. By installing the double floor 153 so as to cover the entire room-side floor surface 151, the height of the floor surface of the double floor 153 can be made approximately the same as the height of the corridor-side floor surface 152.

[0039] As shown in Fig. 6, the double floor 153 has a floor panel 1531 and a support member 1532. The floor panel 1531 is a plate-like member arranged along the horizontal direction, and is approximately rectangular when viewed from above. The support member 1532 is approximately columnar along the up-down direction. A plurality of support members 1532 are attached to the lower surface of the floor panel 1531, and support the floor panel 1531.

[0040] At a work site before the double floor 153 is installed on the room-side floor 151, a step occurs between the room-side floor 151 and the corridor-side floor 152. In this case, a slope device 100 is installed on the room-side floor 151 close to the end of the corridor-side floor 152 so that workers, transport carts, etc. can easily pass between the room-side floor 151 and the corridor-side floor 152. Meanwhile, at a work site where the double floor 153 is being installed over the entire surface of the room-side floor 151, the double floor 153 is installed continuously from the corridor-side floor 152, and a step occurs between the room-side floor 151 and the upper surface of the floor panel 1531 of the double floor 153. In this case, the slope device 100 is installed on the room-side floor 151 close to the end of the floor panel 1531 so that workers, transport carts, etc. can easily pass between the room-side floor 151 and the upper surface of the floor panel 1531.

[0041] In the following, as shown in FIG. 6, a method of installing the slope device 100 at a work site where a raised floor 153 is being installed over the entire surface of a floor surface 151 on the room side will be described. Here, among the work sites shown in FIG. 6, the height from the floor surface 151 on the room side to the floor surface 152 on the corridor side is set as the height Ha of the floor surface on the corridor side. The height Ha of the floor surface on the corridor side is, for example, approximately 100 mm. Approximately 100 mm means a range of, for example, 95 mm to 105 mm. Also, the height from the floor surface 151 on the room side to the upper surface of the floor panel 1531 is set as the height Hb1 of the upper surface of the floor panel, and the height from the floor surface 151 on the room side to the lower surface of the floor panel 1531 is set as the height Hb2 of the lower surface of the floor panel. Here, the height Hb1 of the upper surface of the floor panel is lower than the height Ha of the floor surface on the corridor side (Hb1 < Ha). The height Hb1 of the upper surface of the floor panel is, for example, approximately 90 mm. Approximately 90 mm means a range of, for example, 85 mm to 95 mm. Thus, Hb1 < Ha because it is assumed that, for example, a floor carpet with a thickness of 10 mm is laid on the upper surface of the floor panel 1531. Therefore, finally, when the floor carpet is laid, there is no height difference between the corridor and the room, and it becomes approximately flat.

[0042] Also, the height of the slope portion 110 of the present embodiment is set as the height H of the slope portion 110. The height H of the slope portion 110 is lower than the height Hb1 of the upper surface of the floor panel 1531 (H < Hb1). Also, the height H of the slope portion 110 is higher than the height Hb2 of the lower surface of the floor panel 1531 (H > Hb2). The height H of the slope portion 110 is, for example, approximately 80 mm. Approximately 80 mm means a range of, for example, 75 mm to 85 mm.

[0043] First, the operator brings the slope device 100 into the work site. Next, the operator grounds the grounding portions 122 of the support portions 120R and 120L on the floor surface 151 on the room side near the step formed by the floor panel 1531, and grounds the first slope portion 111 and the second slope portion 112 of the slope portion 110 on the floor surface 151 on the room side away from the step.

[0044] Next, the operator adjusts the orientation and position of the slope device 100 so that the rear end of the main slope portion 113 contacts the end of the floor panel 1531. At this time, since the height H of the slope portion 110 is higher than the height Hb2 of the lower surface of the floor panel, the main slope portion 113 can contact the floor panel 1531, preventing it from entering under the lower surface of the floor panel 1531. Also, at this time, since the height H of the slope portion 110 is lower than the height Hb1 of the upper surface of the floor panel, the rear end of the main slope portion 113 is at a position lower than the upper surface of the floor panel 1531.

[0045] Further, even if there are some irregularities on the floor 151 on the room side where the anti-slip portion 130 of the slope device 100 is grounded, by rotating between the rotating portions 1121, 1135 and the rotated portions 1111, 1122, the anti-slip portion 130 can be grounded on the floor 151 on the room side. Finally, the operator can install the slope device 100 on the floor 151 on the room side by fixing it to the floor using an anchor bolt or the like through the hole 1113 or the like of the first slope portion 111.

[0046] In this way, by installing the slope device 100, an operator, a transport cart, etc. can easily pass through the step formed by the double floor 153. For example, assume a case where an operator passes a transport cart from a corridor into a room. In this case, it can be assumed that the transport cart is loaded with equipment and materials (such as windows and ceiling materials) for attachment to the room and is heavy. Here, the height Hb1 of the upper surface of the floor panel 1531 is lower than the height Ha of the floor on the corridor side (Hb1 < Ha), and the height H of the slope portion 110 is lower than the height Hb1 of the upper surface of the floor panel 1531 (H < Hb1). Therefore, there is a slight height difference between the floor 152 on the corridor side and the floor panel 1531, and between the floor panel 1531 and the slope portion 110. However, when passing from the corridor into the room, since it is a passage from a higher place to a lower place, even if it is heavy, for example, it is possible to pass through the height difference using gravity without lifting the transport cart. On the one hand, assume a case where an operator passes through from a room to a corridor using a transport cart. In this case, it can be assumed that the capital equipment and materials are unloaded in the room and the transport cart is lightweight. Therefore, even if there is a slight height difference between the floor surface 152 on the corridor side and the floor panel 1531, and between the floor panel 1531 and the slope portion 110, and even if the passage is from a lower place to a higher place, since it is a lightweight transport cart, it can easily pass through the height difference.

[0047] Here, a method of installing the slope device 100 at a work site during the process of installing the double floor 153 across the entire floor surface 151 on the room side has been described. However, even at a work site before the double floor 153 is installed on the floor surface 151 on the room side, the slope device 100 can be installed in the same way. In this case, since the slope device 100 is installed on the floor surface 151 on the room side close to the end of the floor surface 152 on the corridor side without passing through the double floor 153, the height difference between the height H of the slope portion 110 and the height ha of the floor surface 151 on the corridor side may be, for example, 10 mm or more. However, the height H of the slope portion 110 is lower than the height ha of the floor surface 151 on the corridor side (H < Ha). Therefore, as described above, when going from the corridor to the room, gravity can be utilized, and when going from the room to the corridor, a lightweight transport cart can easily pass through the height difference.

[0048] As described above, the slope device 100 of the present embodiment includes a slope portion 110 that is arranged obliquely, and a support portion 120 that supports the slope portion 110 at a constant height. In this way, by fixing the height of the support portion 120, the operator does not need to adjust the height, and it is possible to suppress the time-consuming adjustment.

[0049] (First Modification Example) FIG. 7 is a perspective view showing a case where the slope devices 100 are arranged side by side. In the above embodiment, the case where one slope device 100 is used has been described, but multiple slope devices may be used. For example, when it is desired to allow a wide person or object to pass at a gradient, the slope devices 100 are arranged side by side with no gaps between them as shown in FIG. 7. In this case, the slope devices 100 may have a connecting portion and a connected portion at the left and right ends, respectively. By connecting the connecting portion of one slope device 100 to the connected portion of the other slope device 100, the slope devices 100 can be prevented from being separated from each other.

[0050] (Second Modification) FIG. 8 is a perspective view showing the slope device 100 with side guards attached thereto. As shown in Fig. 8, the slope device 100 may have side guards 160 attached to both left and right ends of the slope section 110. The side guards 160 prevent people or objects from falling off the left and right ends when passing over the slope section 110. The side guards 160 are made of an aluminum alloy, are hollow, and have a substantially trapezoidal cross section, but may be made of other materials and have other cross-sectional shapes.

[0051] The present invention has been described above using various embodiments, but the present invention is not limited to the above-described embodiments, and modifications and variations are possible within the scope of the present invention, and the embodiments and modified examples may be combined as appropriate.

[0052] In the above embodiment, the supporting portion 120 supports the slope portion 110 in a state in which the height direction is fixed, but this is not limited to the above case. In other words, if it is not intended to provide a slope device with a fixed height, the supporting portion 120 may support the slope portion so that the height direction is adjustable. In the above embodiment, the height H of the slope portion 110 is, for example, approximately 80 mm, but is not limited to this. For example, the height H of the slope portion 110 may be any of 50 mm or more, 60 mm or more, 70 mm or more, 80 mm or more, and 90 mm or more, or may be any of 100 mm or less, 90 mm or less, 80 mm or less, 70 mm or less, and 60 mm or less.

[0053] In the above embodiment, the linear portion 140 is disposed at the rear end of the main slope portion 113, but it may be disposed at a position other than the rear end. For example, it may be disposed approximately at the center in the left-right direction of the slope portion 110 along the front-rear direction to improve visibility in the traveling direction, or may be disposed in the left-right direction of the slope portion 110 to visually recognize the distance to the slope portion 110.
