The slope device 100 of the present embodiment includes the slope portion 10 and the support portion 50.

First, the slope unit 10 will be described.
The slope portion 10 is disposed at an incline, and has a function of passing a person or an object with a gentle slope to the level difference. The slope portion 10 has, for example, a substantially rectangular shape whose front and rear lengths are longer than the left and right lengths in a plan view.
The slope unit 10 includes a main slope unit 11, a first slope unit 21, a second slope unit 31, and a third slope unit 41. The slope portion 10 is disposed in order of the first slope portion 21, the second slope portion 31, the third slope portion 41, and the main slope portion 11 from the rear side toward the front side.

The main slope portion 11 is located between the third slope portion 41 and the upper stage of the step. The main slope portion 11 has a plurality of (e.g., eight) slope members 12 and a plurality (e.g., five) large pulling members 16.
The slope member 12 is, for example, a substantially flat plate whose left and right lengths are longer than front and rear lengths. The slope member 12 is made of, for example, an aluminum alloy, and is formed by extrusion. In addition, the slope members 12 are arranged in parallel in the front and back without a gap. Furthermore, the slope member 12 is integrally provided with a ridge as a non-slip projection on the upper surface in the lateral direction (width direction). In addition, it is not restricted to a case where the non-slip projections are convex lines, and it may be configured by blasting or fixing a checker plate over the entire upper surface. The configuration of the non-slip projections is the same as in the other slope portions.
In addition, the slope member 12 at the front of the main slope portion 11 and the slope member 12 at the central portion of the main slope portion 11 have holes 13 for accessing adjustment members 58 and 68 described later on both left and right sides. Have.

Further, the slope member 12 at the rear of the main slope portion 11 is different in shape from the other slope members 12.
Fig.3 (a) is the enlarged view to which a part of side view of FIG.2 (b) was expanded. In FIG. 3A, it is illustrated in a state of being transmitted through angle members 36 and 46 described later. As shown in FIG. 3A, the rear slope member 12 has a substantially circular turning portion 14 at its rear end. The pivoting portion 14 is engaged with a pivoted portion 43 of the third slope portion 41, which will be described later, and pivots relative to each other. That is, the third slope portion 41 can rotate around an axis along the lateral direction of the rotation portion 14 with respect to the main slope portion 11. In addition, the rotation part 14 and the to-be-rotated part 43 contact each other when the fixed rotation range is exceeded, and the rotation is restricted.
The rear slope member 12 has a holding portion 15 extending forward from the rear end. There is a gap above the holding portion 15, and the holding portion 15 holds the large pulling member 16 inserted into the gap from the front side from the lower side.

  The large pulling member 16 is disposed on the lower surface of the slope member 12 to improve the strength of the main slope portion 11. The large pulling member 16 is a hollow member having a substantially rectangular cross section along the front-rear direction. The pulling member 16 is made of, for example, an aluminum alloy, and is formed by extrusion. As shown by a two-dot chain line in FIG. 2A, the plurality of large pulling members 16 are arranged in parallel at the left and right with an interval. The large pulling member 16 is fixed to the lower surface of the slope member 12 using a bolt or a rivet. Therefore, each slope member 12 and each large pulling member 16 are configured to intersect with each other.

The first slope portion 21 is in contact with the lower end of the step, and forms an inclined surface continuous from the lower end. The first slope portion 21 is located on the rear side of the second slope portion 31. The first slope portion 21 has a plurality of (for example, six) slope pieces 22.
The slope piece 22 is, for example, a substantially flat plate whose front and rear lengths are longer than the left and right lengths. The slope piece 22 is made of, for example, an aluminum alloy, and is formed by extrusion. The plurality of slope pieces 22 are disposed side by side in parallel with almost no gap. Further, the sloped piece 22 is integrally provided with a convex streak as a non-slip projection on the upper surface in the left-right direction. The slope pieces 22 may have a substantially flat plate shape whose front and rear lengths are shorter than the left and right lengths, and may be made of a flexible synthetic resin.

Moreover, as shown to Fig.3 (a), the slope piece 22 has the to-be-rotated part 23 in a front end. The pivoted portion 23 engages with a pivoting portion 32 of the second slope portion 31 described later and pivots relative to each other. That is, the slope piece 22 can rotate around an axis along the left-right direction of the rotation portion 32 with respect to the second slope portion 31. In addition, the rotation part 32 and the to-be-rotated part 23 contact each other when the fixed rotation range is exceeded, and the rotation is restricted. Since the slope pieces 22 of the present embodiment are disposed in parallel on the left and right, the slope pieces 22 can be independently rotated with respect to the second slope portion 31.
The sloped piece 22 has seat portions 24a and 24b at the rear end and the front end, respectively, which are in contact with the lower end of the step. The seat portions 24 a and 24 b are formed in the left-right direction of the slope piece 22. The seat 24 b is located below the pivoted portion 23.
In addition, the slope piece 22 is colored in a color different from the upper surface of the second slope portion 31, the third slope portion 41, and the main slope portion 11, for example, red, in order to recognize the start of the slope. Is preferred. The coloring includes coloring in surface treatment such as alumite treatment, coloring in which a paint is attached, coloring in which a seal or the like is attached, coloring in which a coloring agent is mixed, and the like.

The second slope portion 31 constitutes an inclined surface which is continuous with the first slope portion 21. The second slope portion 31 is located on the front side of the first slope portion 21 and on the rear side of the third slope portion 41. The second slope portion 31 has, for example, a substantially flat plate shape in which the left and right lengths are longer than the front and rear lengths, and is constituted by one sheet. The second slope portion 31 is made of, for example, an aluminum alloy, and is formed by extrusion. The second slope portion 31 is integrally provided with a ridge as a non-slip projection on the upper surface in the left-right direction.
The second slope portion 31 has a pivoting portion 32 at its rear end and has a pivotable portion 33 at its front end. The pivoted portion 33 is engaged with a pivoting portion 42 of the third slope portion 41 which will be described later, and pivots with respect to each other, that is, the second slope portion 31 rotates relative to the third slope portion 41. It is rotatable around an axis along the lateral direction of the moving part 42. In addition, when the rotation part 42 and the to-be-rotated part 33 exceed a fixed rotation range, they abut each other and rotation is regulated.

  Further, the second slope portion 31 has seat portions 34a and 34b at the center and the front end in the front-rear direction, respectively. A non-slip member 35 such as rubber is coupled to the lower end of the seat portion 34a. Further, the seat portion 34 b is located below the pivoted portion 33 and is grounded to the lower side in a state of being bifurcated in the front and rear direction. Even when a person or a thing moves back and forth between the second slope portion 31 and the third slope portion 41 by grounding the seat portion 34b at two places, the second slope portion 31 is the seat portion It is possible to prevent swinging in a seesaw shape around 34b.

The third slope portion 41 constitutes an inclined surface continuous from the second slope portion 31. The third slope portion 41 is located on the front side of the second slope portion 31 and on the rear side of the main slope portion 11. The third slope section 41 has the same configuration as that of the second slope section 31, and will be described focusing on different points.
The third slope portion 41 has a pivoting portion 42 at its rear end and has a pivotable portion 43 at its front end. As described above, the pivoted portion 43 fits into the pivoting portion 14 of the main slope portion 11 and pivots relative to each other. That is, the third slope portion 41 can rotate around an axis along the lateral direction of the rotation portion 14 with respect to the main slope portion 11.

  Further, the third slope portion 41 has seat portions 44a and 44b at the center and the front end in the front-rear direction, respectively, which are in contact with the lower end of the step. A non-slip member 45 such as rubber is coupled to the lower end of the seat portion 44a. The seat portion 44b is located below the pivoted portion 43, and is grounded to the lower side in a bifurcated state.

  It should be noted that since the pivoting portion 32 and the pivoted portion 23, the pivoting portion 42 and the pivoted portion 33, and the pivoting portion 14 and the pivoted portion 43 are respectively fitted, they do not separate in the front and rear direction. , Slide relative to each other in the lateral direction. Therefore, L-shaped angle members 36 are fixed to the second slope portion 31 as stopper members at both ends in the left-right direction. The angle member 36 regulates the first slope portion 21 and the third slope portion 41 not to slide in the left-right direction. In addition, the third slope portion 41 has L-shaped angle members 46 as stopper members at both ends in the left-right direction. The angle member 46 regulates the main slope portion 11 so as not to slide in the left-right direction.

Next, the support unit 50 will be described.
The support portion 50 is disposed below the slope portion 10. Further, the support portion 50 supports the slope portion 10 in an adjustable manner in the height direction. The support portion 50 of the present embodiment has a first support portion 50a and a second support portion 50b which are located apart in the front-rear direction.

The first support portion 50 a is located on the center side in the front-rear direction of the slope portion 10.
The first support portion 50 a has a joist member 51 and two support units 52.
The joist member 51 is disposed on the lower surface of the large pulling member 16 to improve the strength of the main slope portion 11. The joist member 51 has a length from the right end in the left-right direction of the slope portion 10 to the left end, and is disposed so as to overlap the holes 13 on both sides formed in the slope member 12 at the central portion of the main slope portion 11 in plan view Be done. The joist member 51 is made of, for example, iron and is a member having a substantially U-shaped cross section. The joist member 51 is fixed to the lower surface of the large pulling member 16 using a bolt or a rivet. Accordingly, the joist members 51 and the large pulling members 16 are configured to intersect with each other.

The two support units 52 are disposed on the left and right sides of the joist member 51. Specifically, the two support units 52 are disposed so as to overlap the holes 13 on both sides formed in the slope member 12 at the central portion of the main slope portion 11 in plan view. The two support units 52 have the same configuration.
FIG. 4 is a cross-sectional view taken along the line I-I of FIG.
As shown in FIG. 4, the support unit 52 includes a swing support portion 53, a swing portion 54, and an adjustment member 58.
The swing support portion 53 swingably supports the swing portion 54 and supports the adjustment member 58 in an adjustable manner in the height direction. The rocking support portion 53 is, for example, an iron member, and is a substantially U-shaped member that opens downward when viewed from the front-rear direction. Further, a nut 57 as a female screw portion is fixed to the U-shaped inside of the rocking support portion 53 by welding or the like in a state in which the axis line is along the height direction.

  The swinging portion 54 swings with respect to the swing support portion 53. The swinging portion 54 is, for example, an iron member, and is a substantially U-shaped member that opens downward when viewed from the front-rear direction. The swinging portion 54 has a shape in which the swinging support portion 53 is enlarged, and overlaps in a state of being loosely fitted to the outside of the swinging support portion 53. The swinging support portion 53 and the swinging portion 54 are connected in a state in which the hanging side plates respectively have a certain amount of play by the bolt 55 and the nut 56. Therefore, the swinging portion 54 can swing around the axis (La) of the bolt 55 with respect to the swing support portion 53, that is, around the axis along the left-right direction. In addition, the rocking portion 54 is fixed to the lower surface of the joist member 51 with the upper surface using welding or the like.

The adjusting member 58 can adjust the amount of protrusion projecting from the lower side of the slope portion 10, and supports the slope portion 10 by grounding the lower end of the step. As the adjustment member 58, a so-called adjuster bolt can be used. The adjustment member 58 is grounded at the lower end of the step and has a receiving seat 59 rotatable around the axis of the adjustment member 58. On the other hand, the adjustment member 58 has an operation hole at the upper end where an operator can insert a tool T such as a hexagonal wrench. The male screw portion of the adjustment member 58 is screwed with the nut 57 of the swing support portion 53, whereby the adjustment member 58 is disposed with its axis line along the height direction. Here, the swinging portion 54 and the joist member 51 each have a hole through which the adjusting member 58 is inserted. Therefore, the adjustment member 58 passes through the swinging portion 54 and the joist member 51, and the upper end is positioned in the hole 13 of the slope portion 10.
Here, the operator inserts the tool T into the operation hole at the upper end of the adjustment member 58 and rotates it in one direction, so that the position screwed with the nut 57 changes, and the whole advances downward. Do. On the other hand, when the worker rotates in the other direction, the position screwed with the nut 57 changes, and the whole retracts upward. Thus, the worker can adjust the amount of projection of the adjustment member 58 protruding from the lower side of the slope portion 10 by rotating the adjustment member 58.

The second support portion 50 b is located on the front end side of the slope portion 10. In the following, a configuration different from that of the first support portion 50a in the second support portion 50b will be mainly described.
The second support 50 b has a joist 61, two support units 62, and a ground 70.
The joist member 61 has the same configuration as the joist member 51 of the first support portion 50a, and is disposed so as to overlap the holes 13 on both sides formed in the slope member 12 of the front end of the main slope portion 11 in plan view. .

The two support units 62 are disposed on the left and right sides of the joist member 61. Specifically, the two support units 62 are arranged to overlap the holes 13 on both sides formed in the slope member 12 at the front end of the main slope portion 11 in plan view. The two support units 62 have the same configuration.
FIG. 5 is a cross-sectional view taken along the line II-II in FIG. 2B and viewed from the arrow direction.
As shown in FIG. 5, the support unit 62 includes a swing support portion 63, a swing portion 64, and an adjustment member 68.
The swing support portion 63 swingably supports the swing portion 64 and supports the adjustment member 68 in an adjustable manner in the height direction. The rocking support portion 63 is, for example, an iron member, and is a substantially U-shaped member that opens upward when viewed from the front-rear direction. Further, a nut 67 as a female screw portion is fixed to the U-shaped exterior of the rocking support portion 63 by welding or the like in a state where the axis line is along the height direction.

  The swinging portion 64 swings with respect to the swing support portion 63. The swinging portion 64 has the same configuration as the swinging portion 54 of the first support portion 50a. The swinging portion 64 overlaps with the pair of side plates loosely fitted to the pair of side plates of the swing support portion 63. The swing support portion 63 and the swing portion 64 are connected in a state in which the side plates have a certain amount of play by the bolts 65 and the nuts 66. Therefore, the swinging portion 64 can swing around the axis (Lb) of the bolt 65 with respect to the swing support portion 63, that is, around the axis along the left-right direction. In addition, the swinging portion 64 is fixed to the lower surface of the joist 61 by using welding or the like.

The adjusting member 68 can adjust the amount of protrusion projecting from the lower side of the slope portion 10, and supports the slope portion 10 by grounding it on the lower side of the step. The adjustment member 68 has the same configuration except that the male screw portion is longer than the adjustment member 58 of the first support portion 50a. The adjustment member 68 is grounded at the lower end of the step and has a receiving seat 69 rotatable around the axis of the adjustment member 68.
Therefore, by inserting the tool T into the operation hole at the upper end of the adjustment member 68 and rotating it in one direction, the position screwed with the nut 67 changes and the whole advances downward. . On the other hand, when the worker rotates in the other direction, the position screwed with the nut 67 changes, and the whole retracts upward. Thus, the worker can adjust the amount of projection of the adjustment member 68 protruding from the lower side of the slope portion 10 by rotating the adjustment member 68.

The ground portion 70 is in contact with the upper end of the step.
FIG. 3 (b) is an enlarged view of a part of FIG. 2 (b). As shown in FIG. 3 (b), the ground portion 70 is located on the front side of the main slope portion 11. The ground portion 70 is substantially L-shaped as viewed in the left-right direction, and the length in the left-right direction is substantially the same as that of the slope portion 10. The ground portion 70 is made of, for example, iron and is formed by bending.
The ground unit 70 includes a fixing unit 71 and a placement unit 72.
The fixing portion 71 has a plate shape along the vertical direction. The fixing portion 71 is fixed to the front end of the swing support portion 63 using a bolt, a rivet or the like. Accordingly, even if the inclination angle of the slope portion 10 is changed, the ground portion 70 can always maintain a fixed posture without being synchronized in synchronization with the slope portion 10.
The placement portion 72 is a substantially horizontal plate shape, and by being placed on the upper stage of the step, the ground portion 70 is in contact with the upper stage of the step. The mounting portion 72 is positioned slightly higher than the front end of the main slope portion 11. In addition, in the placement portion 72, a gap between the mounting portion 72 and the main slope portion 11 does not interfere with the slope portion 10 when the slope portion 10 swings in synchronization with the swinging portion 64 and the inclination angle is changed. (See FIG. 6 described later). The placement unit 72 also has a plurality of holes 73 for fixing to the upper stage of the step.
In addition, the placement portion 72 may be colored in a color different from the top surface of the second slope portion 31, the third slope portion 41, and the main slope portion 11, for example, red, in order to recognize the start of inclination. preferable. The coloring includes coloring at the surface treatment, coloring for attaching the paint, coloring for sticking the seal and the like.

Next, a method of installing the slope device 100 configured as described above at a work site having a step will be described. Here, in order to secure a sufficient length in the left-right direction, the two slope devices 100 are installed in parallel in the left-right direction.
First, the worker brings the two slope devices 100 assembled in advance to the work site. At this time, the adjustment member 58 of the support unit 52 of each slope device 100 and the adjustment member 68 of the support unit 62 are in a state where the receiving seat 59 and the receiving seat 69 are close to the main slope portion 11 respectively. That is, the amount of protrusion of the adjusting members 58 and 68 from the lower side of the slope portion 10 is short.

Next, the operator places the mounting portion 72 of the grounding portion 70 on the upper stage of the step, and the first slope portion 21, the second slope portion 31, and the third slope portion 41 of the slope portion 10 are stepped. Ground to the bottom of the At this time, the operator arranges the two slope devices 100 in parallel with almost no space left and right.
Next, the operator inserts the tool T into the operation holes of the adjustment members 58 and 68 through the holes 13 of the main slope portion 11 and rotates the adjustment members 58 and 68 downward by rotating in one direction. . The operator rotates the receiving seat 59 of the adjusting member 58 and the receiving seat 69 of the adjusting member 68 until it contacts the lower end of the step. Therefore, the slope portion 10 is supported by the adjustment members 58 and 68 of the support portion 50.
Next, the worker can install the slope device 100 by fixing the grounding portion 70 to the upper stage of the step using the bolt or the like through the hole 73 of the mounting portion 72. As described above, in the slope device 100 according to the present embodiment, the operator does not need to assemble the slope device 100. Therefore, the slope device 100 can be easily installed. Here, although the case where two slope devices 100 are installed in parallel in the left and right direction has been described, only one slope device 100 may be installed, and three or more slope devices 100 in parallel in the left and right directions. It may be installed as

  In a state where the slope device 100 is installed, the adjustment members 58 and 68 of the support portion 50 support the slope portion 10. Therefore, the load when passing over the slope portion 10 is not received by only the first slope portion 21 or the like or the ground portion 70, but is received by the lower portion through the adjustment members 58 and 68 of the support portion 50, The strength of the slope device 100 can be improved.

  FIG. 6 is a side view showing a state in which the slope device 100 is installed on the upper step which is higher than the upper step shown in FIG. 2 (b). In FIG. 6, the adjustment members 58 and 68 are grounded at the lower end of the step by adjusting so that the amount of projection of the adjustment members 58 and 68 protruding from the lower side of the slope portion 10 is longer than that in FIG. ing. Thus, since the support part 50 supports the slope part 10 adjustably in the height direction via the adjustment members 58 and 68, it can respond to various level | step differences. In the present embodiment, the height from the lower stage to the upper stage can correspond to, for example, 110 mm to 210 mm.

  Further, the slope portion 10 swings with respect to the swing support portion 53 via the swing portion 54, that is, with respect to the adjustment member 58. Similarly, the slope portion 10 swings with respect to the swing support portion 63 via the swing portion 64, that is, with respect to the adjustment member 68. That is, even when the amount of protrusion of the adjustment members 58 and 68 is adjusted to be installed at different steps, the distance between the swing support portion 53 and the swing portion 54 and the swing support portion 63 and the swing portion 64 And the inclination angle of the slope portion 10 can be changed. Therefore, it can respond to various level differences.

  Moreover, the support part 50 has the earthing | grounding part 70 earth | grounded to the upper stage of a level | step difference. Specifically, the ground portion 70 is not provided in the slope portion 10, and is connected to the swing support portion 63 of the support portion 50. Therefore, even if the inclination angle of the slope portion 10 is changed by installing on different steps, the ground portion 70 does not incline in synchronization with the inclination angle of the slope portion 10, so Unintended gaps and steps can be prevented from occurring between the two.

Furthermore, the mounting portion 72 of the grounding portion 70 is positioned slightly higher than the front end of the main slope portion 11. In other words, the front end of the main slope portion 11 is lower in height than the mounting portion 72 of the ground portion 70. Therefore, even when, for example, a transport carriage passes from the ground portion 70 toward the slope portion 10, the transport carriage can be prevented from hitting the front end of the slope portion 10. Therefore, since the external force which slope part 10 receives from the front side can be controlled, breakage of slope part 10 and position shift of slope part 10 can be prevented.
Further, since there is a gap between the ground portion 70 and the slope portion 10, the slope portion 10 swings in synchronization with the swing portion 64 and does not interfere with the slope portion 10 when the inclination angle is changed. You can do so.

  Further, between the first slope portion 21 and the second slope portion 31, between the second slope portion 31 and the third slope portion 41, and between the third slope portion 41 and the main slope portion 11. Are pivotable about axes along the left and right direction, respectively. Therefore, when the first slope portion 21, the second slope portion 31, and the third slope portion 41 are grounded to the lower side of the step, each slope portion follows the unevenness even if the lower side is uneven. Rotate between. Therefore, even if the lower portion is uneven, each slope portion can be grounded, so that the slope portion 10 can be prevented from rising.

  Further, the first slope portion 21 has slope pieces 22 disposed in parallel on the left and right. Since the slope pieces 22 are rotatable independently of each other with respect to the second slope portion 31, when the first slope portion 21 is grounded to the lower side of the step, the lower side has undulation in the horizontal direction at the lower side. Each slope piece 22 pivots so as to follow ups and downs even when it is present. Therefore, each slope piece 22 can constitute an inclined surface so that it may continue from a lower part. When the slope piece 22 is made of a material (for example, made of synthetic resin) that is more flexible than the second slope portion 31 or the like, the slope piece 22 itself can be flexed to further follow up and down.

In the present embodiment, the support portion 50 of the first embodiment is replaced with the support portion 80, and the ground portion 70 is replaced with the ground portion 95. The same components as those of the first embodiment are denoted by the same reference numerals, and the description thereof will be omitted as appropriate.
FIG. 7 is a side view showing an example of the configuration of the slope device 200. As shown in FIG. FIG. 8 is a side view showing an example of the configuration around the support portion 80 in the slope device 200. As shown in FIG. FIG. 9 is a cross-sectional view taken along the line III-III shown in FIG. 7 and viewed from the arrow direction. In FIG. 7 and FIG. 8, it is illustrated in a state of being transmitted through an angle member 97 described later.
The support portion 80 of the present embodiment is configured only at the front end of the slope portion 10. The support portion 80 includes a swing portion 81, a swing support portion 84, an adjustment member 88, and a ground portion 95.

The swinging portion 81 swings with respect to the swing support portion 84. The swinging portion 81 is located on the front side of the main slope portion 11 and on the rear side of the ground portion 95. The swinging portion 81 has substantially the same length as the slope portion 10 in the left-right direction. The swinging portion 81 in the present embodiment functions as a part of the slope portion 10 by being inclined so that the upper surface is continuous with the main slope portion 11.
The swinging portion 81 is made of, for example, an aluminum alloy, and is formed by extrusion. The swinging portion 81 has a coupling portion 82 at the rear end. The coupling portion 82 couples the large pulling member 16 by holding the front end of the large pulling member 16 from above and below and fixing the front end using bolts and rivets.

The swinging portion 81 also has a guided portion 83 whose swing is guided by the guide portion 85 of the swing support portion 84. The guided portion 83 is formed in a concave shape with respect to the lower surface of the swinging portion 81. Specifically, the guided portion 83 is formed as a part of a circle curved in an arc shape toward the upper surface centering on a horizontal axis (Lb) along the left-right direction when viewed from the left-right direction. The guided portion 83 is formed from the right end in the left-right direction of the swinging portion 81 to the left end.
The swinging portion 81 also has holes 13 for accessing the adjusting member 88 on both the left and right sides, as in the first embodiment.

The swing support portion 84 swingably supports the swing portion 81 and supports the adjustment member 88 in an adjustable manner in the height direction. The swing support portion 84 has substantially the same length as the swing portion 81 in the left-right direction.
The swing support portion 84 is made of, for example, an aluminum alloy, and is formed by extrusion. Further, the swing support portion 84 has a guide portion 85 which guides the guided portion 83 of the swing portion 81 at the top. The guide portion 85 is formed to be convex toward the upper side. Specifically, the guide portion 85 is a part of a circle centered on the axis (Lb) when viewed in the left-right direction, and the center is formed hollow for lightening. Further, at the top of the guide portion 85, a hole communicating with the hole 13 is formed in plan view.

In addition, the rocking support portion 84 has a substantially U-shaped base 86 that opens downward at a lower portion as viewed in the left-right direction. The base 86 is formed with a hole communicating with the hole 13 in a plan view. Further, a nut 87 as a female screw portion is disposed on the base portion 86 via the mounting plate 90. Specifically, the mounting plate 90 is attached to the base portion 86 in a fitted state, and a nut 87 is fixed to the lower surface of the mounting plate 90 by welding or the like in a state in which the axis extends in the height direction.
The base portion 86 is not limited to a substantially U-shaped opening, and may have a substantially horizontal plate shape. In this case, the mounting plate 90 is fixed to the lower surface of the base 86 using a bolt, a rivet or the like.

  The adjusting member 88 can adjust the amount of protrusion projecting from the lower side of the swinging portion 81, and supports the slope portion 10 by grounding the lower end of the step. The support 80 has two adjustment members 88 on the left and right sides of the swing support 84. The adjustment member 88 has the same configuration as the adjustment member 68 of the first embodiment. The adjusting member 88 is grounded at the lower end of the step and has a receiving seat 89 rotatable around the axis of the adjusting member 88. The male screw portion of the adjustment member 88 is screwed with the nut 87 fixed to the swing support portion 84, whereby the adjustment member 88 is disposed with the axis line along the height direction. The guide portion 85 and the base portion 86 of the swing support portion 84 have holes communicating with the holes 13, so the upper end of the adjustment member 88 is located in the hole 13 of the swing portion 81.

  Further, a retaining member 92 is connected to the receiving seat 89. The retaining member 92 is, for example, a bolt. As shown in FIG. 9, the retaining members 92 are respectively positioned outside in the left-right direction of the adjusting member 88. The retaining member 92 passes through the mounting plate 90 and the swing support portion 84 and approaches the top of the swing support portion 84 with the axis line extending in the height direction. Further, the retaining member 92 has a stopper 93 at the top. The stopper portion 93 is, for example, a head of a bolt and has a diameter larger than the diameter of the male screw portion of the bolt. Since the retaining member 92 is connected to the receiving seat 89, it moves in synchronization with the movement of the adjusting member 88 in the height direction. When the adjustment member 88 advances excessively downward, the adjustment member 88 comes out of the nut 87 when the stopper portion 93 of the retaining member 92 abuts on the upper surface of the contact portion 91 of the mounting plate 90. To prevent. The contact portion 91 is a U-shaped upper surface projecting downward from the mounting plate 90, and is located below the lower surface of the mounting plate 90.

The pivot shaft 96 inserts the front end of the swinging portion 81 and the rear end of the ground portion 95 with the axis line extending in the left-right direction. Therefore, even if the inclination angle of the slope portion 10 changes, the ground portion 95 can be grounded evenly to the upper end of the step. Further, by rotating the front end side of the ground portion 95 toward the receiving seat 89 of the adjusting member 88, the slope device 200 can be carried compactly.

The operator inserts the tool T into the operation hole of the adjustment member 88 through the hole 13 of the swinging portion 81 and rotates the adjustment member 88 in one direction, whereby the adjustment member 88 advances downward. The operator rotates the receiving seat 89 of the adjustment member 88 to the ground at the lower end of the step, whereby the slope 10 is supported by the adjustment member 88 of the support 80.
The two-dot chain line shown in FIG. 8 shows a state in which the adjusting member 88 has been adjusted to the limit. At this time, the stopper portion 93 of the retaining member 92 is in contact with the upper surface of the contact portion 91 of the mounting plate 90.
Since the swinging portion 81 and the swing support portion 84 are respectively fitted to each other, they do not separate in the height direction, but they slide relative to each other in the lateral direction. Therefore, an L-shaped angle member 97 is fixed to both ends of the swinging portion 81 in the left-right direction as a stopper member.

  According to the present embodiment, for example, an aluminum alloy can be used for the rocking portion 81 and the rocking support portion 84, so that the weight of the slope device 200 can be reduced. Moreover, the adjustment member 88 of the support part 80 supports the slope part 10 in the state in which the slope apparatus 200 was installed similarly to 1st Embodiment. Therefore, the load when passing over the slope portion 10 is not received by only the first slope portion 21 or the like or the ground portion 95, but is received by the lower portion through the adjustment member 88 of the support portion 80, so the slope device The strength of 200 can be improved.

Moreover, since the support part 80 supports the slope part 10 in the height direction so that adjustment is possible via the adjustment member 88, it can respond to various level | step differences.
Further, since the ground portion 95 is rotatably connected to the swing portion 81 functioning as a part of the slope portion 10, even if the inclination angle of the slope portion 10 changes, It can be grounded flat on the upper stage. In addition, it is possible to prevent a gap from being generated between the swinging portion 81 and the ground portion 95.

FIG. 16C is an enlarged view of a part of the protrusion 226. In FIG. 16C, the non-slip member 224 and the non-slip member 234 are in contact with the horizontal floor surface (two-dot chain line). The protrusion 226 has a front side surface 227a and a rear side surface 227b, and a center line Ce of the front side surface 227a and the rear side surface 227b is inclined toward the front side. In addition, the protrusions 226 are formed such that the front side surface 227a and the rear side surface 227b are not parallel to each other, and come closer to each other as they go downward. Here, an angle formed on the front side between the front side surface 227a of the protrusion 226 and the floor is defined as an angle α1, and an angle formed on the rear side between the rear side 227b of the protrusion 226 and the floor is defined as an angle α2. At this time, the protrusion 226 is formed such that the angle α1 is smaller than the angle α2.
The shape described above makes the non-slip member 224 and the non-slip member 234 less likely to move rearward. Therefore, the first slope portion 221 and the second slope portion 231 to which the non-slip member 224 and the non-slip member 234 are respectively fixed become difficult to move in the direction away from the upper stage of the step, and the slope device 500 and the upper stage of the step It is possible to suppress the formation of a gap between them. On the other hand, even if the first slope portion 221 and the second slope portion 231 move to the front side, the gap between the slope device 500 and the upper stage of the step is reduced because it is in the direction approaching the upper stage of the step. Can.

Although the pivoting portion 232 and the pivoted portion 222, and the pivoting portion 214 and the pivoted portion 233 respectively fit in each other, they do not separate in the front-rear direction, but slide relative to each other relative to each other. I will. Therefore, L-shaped angle members 236R and 236L are fixed as stopper members at both ends in the left-right direction on the second slope portion 231. The angle members 236R and 236L restrict the first slope portion 221 and the main slope portion 211 not to slide in the left-right direction.
Here, in the angle members 236R and 236L, the surface and the side surfaces, that is, the exposed surfaces are colored in a color different from the surface of the second slope portion 231, for example, red. The angle members 236R and 236L function as a visual recognition unit for recognizing the left and right ends of the slope unit 210. The coloring includes coloring in surface treatment such as alumite treatment, coloring in which a paint is attached, coloring in which a seal or the like is attached, coloring in which a coloring agent is mixed, and the like. The angle members 236R and 236L are not limited to L-shaped, and may be plate members that only cover the side surfaces of the right end and the left end of the second slope portion 231. It may be a plate member that covers the surface.

Next, the support portion 250 will be described.
The support portion 250 is located below the slope portion 210 and on the front end side of the slope portion 210 in the front-rear direction. The support portion 250 adjustably supports the slope portion 210 in the height direction.
The support 250 of the present embodiment includes a first support unit 251 a and a second support unit 251 b. The first support unit 251a and the second support unit 251b are disposed below the front slope member 212b and on the left and right sides of the front slope member 212b. Specifically, the first support unit 251a and the second support unit 251b are disposed so as to overlap the holes 216 on both sides formed in the main slope portion 211 at the front in plan view. The first support unit 251a and the second support unit 251b have the same basic configuration. Therefore, the first support unit 251a is taken up here to explain the basic configuration of the two, and the different configuration will be described later.

As shown in FIG. 12, the first support unit 251 a has a screwing member 252 and an adjusting member 261.
The screwing member 252 is fixedly attached to the slope portion 210 and screwed with the adjusting member 261. Specifically, the screwing member 252 includes a main body portion 253, a first attachment portion 255, a second attachment portion 256, and a nut 257 as a female screw portion. Here, the main body portion 253, the first attachment portion 255, and the second attachment portion 256 are integral members formed by bending by press forming, and are made of, for example, iron.

The main body portion 253 is in the form of a long plate in the front and rear direction, and has a hole 254 through which the adjusting member 261 is inserted substantially at the center (see FIGS. 20A and 20B described later).
The first attachment portion 255 is substantially U-shaped as viewed in the front-rear direction. Specifically, the first attachment portions 255 extend upward in parallel from the left and right ends on the rear side of the main body portion 253 in a pair. The first attachment portion 255 sandwiches the large pulling member 217 from the left and right, and is fixed to the large pulling member 217 through a plurality of mounting holes using screws, rivets, and the like.
The second attachment portion 256 is substantially hat-shaped as viewed in the front-rear direction. Specifically, the second attachment portion 256 is extended in parallel as a pair from the left and right ends in parallel on the front side of the main body portion 253 and then bent and extended in the left and right direction. The second mounting portion 255 is fixed to the slope member 212 b through a plurality of mounting holes using a screw, a rivet, or the like in a state of being in contact with the lower surface of the slope member 212 b at the front.

  The nut 257 is fixed to the lower surface of the main body portion 253 by, for example, welding in a state of being in communication with the substantially central hole 254 of the main body portion 253. Here, in a state where the first support unit 251a and the second support unit 251b are attached to the slope portion 210, the axis line of the nut 257 is not along the vertical direction when viewed from the front-rear direction, and the intentional predetermined It is inclined at an angle of. That is, the extension direction of the first attachment portion 255 and the second attachment portion 256 so that the main body portion 253 to which the nut 257 is fixed is not intentionally parallel to the horizontal surface when viewed from the front-rear direction. Is designed.

The adjusting member 261 engages with the screwing member 252 and is grounded to the floor surface.
FIG. 18A is a partial cross-sectional view showing the configuration of the adjustment member 261. As shown in FIG. FIG. 18 (b) is a bottom view of the adjustment member 261.
The adjusting member 261 has a bolt 262 as an external thread, a fixing plate 264 and a seat 265. The head side of the bolt 262 is located in the seat 265 and the tip side is exposed. A hole 263 is formed in the end face of the tip end side of the bolt 262. The fixing plate 264 is made of, for example, iron, and has a substantially disc shape having a diameter larger than the head of the bolt 262. The fixing plate 264 is fixed by welding, screwing or the like in a state of being in contact with the head of the bolt 262.

  The seat 265 is made of, for example, resin or rubber, and has a substantially disc shape larger than the head of the bolt 262 and the fixing plate 264. The seat 265 has a space 266 which opens upward at the inside. In the space 266, the head of the bolt 262 and the fixing plate 264 are accommodated. Further, the receiving seat 265 has a plurality of operation parts 267 for allowing the user to turn the adjusting member 261 about the axis around the entire circumference of the outer peripheral surface. Although the operation part 267 is concave shape which goes to the center of the seat 265 from an outer peripheral surface, it is not restricted to such a shape. Further, the receiving seat 265 is not a flat bottom surface, but is a curved surface convex downward. In the bottom surface of the receiving seat 265, the portion passing through the center line Cr is located at the lowermost position. In addition, irregularities are formed on the bottom of the seat 265. Specifically, in the receiving seat 265, annular concave portions 268 and annular convex portions 269 are alternately formed from the center to the outer peripheral edge around the center line Cr. The bottom surface of the receiving seat 265 has a plurality of (for example, four) counterbored portions 270 for preventing the fixing member 271 for fixing the receiving seat 265 to the fixing plate 264 from protruding from the bottom surface of the receiving seat 265 .

Here, in order to assemble and configure the first support unit 251 a, the fixing plate 264 is previously fixed to the bolt 262, and the head of the bolt 262 is accommodated in the space 266 of the receiving seat 265. Next, the adjustment member 261 is assembled by fixing the receiving seat 265 and the fixing plate 264 from the counterbored portion 270 of the receiving seat 265 using a screw, a rivet or the like. Next, the bolt 262 of the adjusting member 261 is screwed into the nut 257 of the screwing member 252 from the lower side, and is inserted into the hole 254 of the main body portion 253. Finally, it is inserted into the hole 263 at the tip of the bolt 262 using the screw 273 (see FIG. 1, FIG. 20A, FIG. 20B), and a washer 272 as a stopper is attached to the tip of the adjustment member 261. One support unit 251a can be assembled.
Although the second support unit 251b has the same configuration as the first support unit 251a, the direction in which the axis of the nut 257 is inclined when viewed from the front-rear direction is the center in the left-right direction of the slope portion 210. The configuration is symmetrical with respect to the line C.
The slope device 500 can be assembled by attaching the assembled first support unit 251a and the second support unit 251b to the main slope portion 211, respectively.

Next, a method of installing the slope device 500 configured as described above at a work site having a step will be described. The operator brings the slope device 500 to the work site. At this time, it is assumed that the amount of protrusion of the adjustment member 261 of the support portion 250 from the lower side of the slope portion is short.
Next, the operator grounds the adjustment member 261 of the support portion 250 to the lower end near the step, and grounds the first slope portion 221 and the second slope portion 231 of the slope portion 210 to the lower end away from the step. .
Next, the worker advances the adjustment members 261 of the first support unit 251a and the second support unit 251b downward. For example, the operator rotates the adjustment member 261 of the first support unit 251a using the operation unit 267 while lifting the slope device 500 with the handle portion 244R, or lifts the slope device 500 with the handle portion 244L. The adjustment member 261 of the second support unit 251b can be rotated using the operation unit 267. The operator advances the adjustment member 261 downward for adjustment so that the height of the front upper end of the front slope member 212b of the main slope portion 211 and the height of the upper end of the step coincide with each other.

Finally, the operator can install the slope device 500 by fixing the lower side of the step using the bolt or the like through the hole 228 of the first slope portion 221.
Note that the method of installing the slope device 500 is not limited to the method described above, and the adjustment member 261 may be advanced downward before the slope device 500 is grounded. Further, the adjustment member 261 of the support portion 250 is kept in a state in which the amount of protrusion from the lower side of the slope portion 210 is long, and the adjustment member 261 is retreated upward to the front upper end of the slope member 212 b at the front. You may adjust so that the height with the upper stage of a level | step difference may correspond.

Next, referring to FIGS. 19 and 20, a state in which the slope device 500 is installed will be described.
19A and 19B are rear views showing the configuration of the slope device 500. FIG. FIG. 19A shows a state in which the amount of projection of the adjustment member 261 is the shortest, that is, a state in which the main slope portion 211 is the lowest (the lower limit of the adjustment range). On the other hand, FIG. 19B shows a state in which the amount of protrusion of the adjustment member 261 is the longest, that is, a state in which the main slope portion 211 is the highest (upper limit of the adjustment range). Thus, by adjusting the amount of projection of the adjustment member 261, the main slope portion 211 pivots about the pivot portion 214, and the height of the main slope portion 211 changes.

Here, as shown in FIGS. 19A and 19B, the adjustment member 261 of the first support unit 251a and the adjustment member 261 of the second support unit 251b are grounded in an inclined state with respect to the floor surface. That is, the axes S of the bolt 262 of the first support unit 251a and the bolt 262 of the second support unit 251b are inclined with respect to the floor surface.
Specifically, in the rear view, the bolt 262 of the first support unit 251a and the bolt 262 of the second support unit 251b are inclined such that the upper sides are close to each other and the lower sides are separated from each other. That is, the bolt 262 of the first support unit 251a and the bolt 262 of the second support unit 251b are substantially V-shaped. Here, since the bottom of the reception seat 265 of the first support unit 251a and the reception seat 265 of the second support unit 251b is a curved surface, the slope device 500 is closer to the center line Cr (see FIG. 18B). The part of the center line C that is biased to the side of the ground and the floor surface are grounded. When vibration or the like is applied to the adjusting member 261 by passing a person or an object over the slope portion 210, the direction of the reaction force received from the floor surface of the adjusting member 261 becomes substantially parallel to the axis S.

Therefore, the adjusting member 261 of the first support unit 251a and the adjusting member 261 of the second support unit 251b mainly move in the left or right direction. However, the adjustment member 261 of the first support unit 251a and the adjustment member 261 of the second support unit 251b are inclined symmetrically to each other, and can not move as a result because the directions to move are opposite to each other. Lateral shift is suppressed in the entire 500.
In any of the states of FIGS. 19A and 19B, the inclination angles of the bolt 262 of the first support unit 251a and the bolt 262 of the second support unit 251b are always constant or substantially constant. .

20A and 20B are cross-sectional views showing part of the slope device 500. FIG. Here, although the 1st support unit 251a is demonstrated, the 2nd support unit 251b is also the same.
FIG. 20A shows a state in which the amount of projection of the adjustment member 261 is the shortest, that is, a state in which the main slope portion 211 is the lowest (the lower limit of the adjustment range). In the state shown in FIG. 20A, the upper end of the adjustment member 261 is located in the hole 216 of the front slope member 212b. Further, since the lower end of the nut 257 is in contact with the surface of the fixing plate 264 of the adjusting member 261, the amount of projection of the adjusting member 261 can not be shorter than this state.
FIG. 20B shows the state where the amount of protrusion of the adjustment member 261 is the longest, that is, the state where the main slope portion 211 is the highest (upper limit of the adjustment range). In the state shown in FIG. 20B, the upper end of the adjustment member 261 is positioned in the hole 254 of the main body portion 253 of the screwing member 252. Further, since the upper end of the nut 257 is in contact with the washer 272 at the upper end of the adjustment member 261, the amount of protrusion of the adjustment member 261 can not be longer than in this state.

Here, as shown in FIG. 20A, the adjusting member 261 is grounded in a state of being inclined with respect to the floor surface. That is, the axis S of the bolt 262 of the adjustment member 261 is inclined with respect to the floor surface. Specifically, in the side view, the bolt 262 of the adjustment member 261 is inclined such that the upper side is close to the step and the lower side is away from the step, in other words, the upper side is forward and the lower side is backward. There is.
From this state, by adjusting the protrusion amount of the adjustment member 261 in the direction of advancing, the inclination of the axis line S of the bolt 262 of the adjustment member 261 changes as the inclination of the slope portion 210 changes. Specifically, the inclination angle of the axis S of the bolt 262 changes so as to be close to the vertical direction with respect to the floor surface.

In the present embodiment, even in the state of FIG. 20B, the adjusting member 261 is not vertical, and is strictly grounded in a slightly inclined state with respect to the floor surface. That is, the axis S of the bolt 262 of the adjustment member 261 is inclined with respect to the floor surface. Specifically, in the side view, the bolt 262 of the adjustment member 261 is inclined such that the upper side is close to the step and the lower side is away from the step, in other words, the upper side is forward and the lower side is backward. There is.
That is, in the adjustment range of the adjustment member 261 from the lower limit to the upper limit, the axis S of the bolt 262 is inclined such that the upper side is close to the step and the lower side is away from the step.

Here, since the bottom surface of the receiving seat 265 of the adjusting member 261 is a curved surface, a portion biased to the step than the center line Cr (see FIG. 18B), that is, a portion biased to the front side and the floor surface Ground it. When vibration or the like is applied to the adjusting member 261 by passing a person or an object over the slope portion 210, the direction of the reaction force received from the floor surface of the adjusting member 261 becomes substantially parallel to the axis S.
Therefore, when vibration or the like is applied to the adjusting member 261 as a person or an object passes on the upper side, the adjusting member 261 tries to move to the front side in the front-rear direction, that is, the step side. Therefore, the formation of a gap between the step and the front slope member 212b is suppressed. Moreover, the annular convex part 269 of the bottom face of the receiving seat 265 is in contact with the floor surface in the inclined state. Therefore, the annular convex portion 269 acts similarly to the projections 226 of the anti-slip member 224 and the anti-slip member 234, and becomes less likely to move in the direction away from the upper step of the step. Can be further suppressed.

In the present embodiment, in the side view, in the adjustment range of the adjustment member 261 from the lower limit to the upper limit, the axis S of the bolt 262 is described such that the upper side approaches the step and the lower side inclines away from the step But it is not limited to this case.
For example, in a state from the lower limit of the adjustment range of the adjustment member 261 to the middle of the adjustment range, the axis S of the bolt 262 may be inclined such that the upper side approaches the step and the lower side separates from the step. Further, assuming that the adjustment range is R, the axis S of the bolt 262 is in a state from the lower limit to R × 3/4 in the adjustment range (more than half the adjustment range and not including all of the adjustment range) The upper side may be close to the step and the lower side may be inclined in a state of being separated from the step. That is, in the upper limit state of the adjustment range, the axis S of the bolt 262 may be perpendicular to the floor surface, and the upper side may be away from the step and the lower side may be inclined to approach the step. In this case, for example, the operator is warned that the range in which the upper side of the axis S of the bolt 262 is close to the step and the lower side is inclined away from the step is the adjustment range of the adjustment member 261. can do.

Next, a case where a plurality of (for example, two) slope devices 500 are installed in parallel in the left and right direction to configure the slope unit 600 will be described.
FIG. 21 is a perspective view showing the configuration of the slope unit 600. As shown in FIG.
First, after the operator installs the first slope device 500a, the operator installs the second slope device 500b on the left side of the first slope device 500a. At this time, the second slope device 500b is installed from the upper side while aligning the second slope device 500b so that the connection portion 242 of the second slope device 500b is connected to the connected portion 243 of the first slope device 500a.
Therefore, the two slope devices 500a and 500b can be installed in parallel in the lateral direction with almost no gap, and the slope unit 600 can be configured. Here, in the entire slope unit 600, the angle members 241R, 241L, 236R, 236L are positioned along the front-rear direction substantially at the center in the left-right direction. Here, the angle members 241R, 241L, 236R, and 236L positioned substantially at the center in the left-right direction correspond to an example of the linear portion. When passing through the slope unit 600, the worker can recognize the approximate center in the width direction using the angle members 241R, 241L, 236R, and 236L positioned at the approximate center in the width direction as an index. Therefore, for example, when the worker travels the carriage and passes through the slope unit 600, the carriage can easily travel along the approximate center in the width direction of the slope unit 600, and the wheel is removed from the slope unit 600. Can be prevented. In addition, the index for recognizing the approximate center in the width direction is not limited to the angle members 241R, 241L, 236R, 236L, but it is possible to attach a paint, attach a seal, or mix a coloring agent. It may be applied. In addition, the index for recognizing the approximate center in the width direction is not limited to the case of being continuous in the front-rear direction, but may be intermittent in the front-rear direction. Even when only one slope device 500 is installed, a linear portion along the front-rear direction may be provided substantially at the center in the width direction.

Next, the ridges as the non-slip projections will be described.
FIG. 22 is a side view or a cross-sectional view showing an example of the ridge 280.
The ridges 280 in the present embodiment are substantially triangular. Here, the ridges 280 are not in the form of an isosceles triangle, but in the shape of a so-called saw blade. Specifically, the ridge 280 has a lower surface 281 a and an upper surface 281 b. Here, among the inclination angles formed by the ridges 280 and the surface F of the slope portion 210, the inclination angle on the acute angle side of the surface 281a on the lower side and the surface F of the slope portion 210 is β1. Further, the inclination angle on the acute angle side between the upper surface 281 b and the surface F of the slope portion 210 is β2. In the ridge 280 of the present embodiment, the inclination angle β2 on the upper side is larger than the inclination angle β1 on the lower side.

Here, it is assumed that the worker travels, for example, a carriage and passes the slope portion 210 of the slope device 500 to the upper stage side. The surface 281 a of the ridge 280 has a relatively low resistance because the angle of inclination with respect to the surface F is gentle, so that the castor of the carriage can easily ride over the ridge 280. On the other hand, after crossing over the ridge 280, the caster caster truck moves from the surface 281b to the surface 281a because the surface 281b of the ridge 280 has a steep inclination angle with respect to the surface F and thus becomes a resistance. Is suppressed.
Therefore, the worker can easily move the slope portion 210 toward the upper stage, but can suppress unintentional movement toward the lower stage after passing through. The shape of the ridges 280 is not limited to the case where the apex of the triangle is a corner, and may be curved. The ridges 280 are preferably provided on all of the main slope portion 211, the first slope portion 221, and the second slope portion 231, but may be provided on at least one of them.

As mentioned above, although this invention was described with embodiment mentioned above, this invention is not limited only to embodiment mentioned above, A change etc. are possible within the scope of the present invention, and can suitably change the embodiment mentioned above. It may be combined.
In addition, although the case where the support part 50 has the 1st support part 50a and the 2nd support part 50b was demonstrated in 1st Embodiment mentioned above, it is not restricted to this case. For example, the support portion 50 may be configured by only the second support portion 50b without the first support portion 50a. Also, for example, the support portion 50 may have first to n-th (n ≧ 3) support portions.
Moreover, although the case where it comprises the support part 80 only by one is demonstrated in 2nd Embodiment and 3rd Embodiment which were mentioned above, it is not restricted to this case. For example, as in the first embodiment, the support 80 may have a first support 80a and a second support 80b. Also, for example, the support portion 80 may have first to n-th (n ≧ 3) support portions.

  Moreover, although the case where the support part 250 has two support units 251a and 251b was demonstrated in 5th Embodiment mentioned above, it is not restricted to this case, You may have three or more support units. For example, in the case where the support 250 includes three support units, the third support unit 251c includes the first support unit 251a and the second support unit, where the third support unit is the third support unit 251c. Place it between 251b. At this time, in the rear view, the bolt 262 of the third support unit 251c is different from the first support unit 251a and the second support unit 251b, and is in a state along the vertical direction without being inclined with respect to the floor surface I assume. On the other hand, in the side view, the bolt 262 of the third support unit 251c is inclined so that the upper side is near the step and the lower side is away from the step, similarly to the first support unit 251a and the second support unit 251b. It shall be. Even when the fourth and subsequent support units are added, they are disposed between the first support unit 251a and the second support unit 251b, and in the same manner as the bolts 262 of the third support unit 251c, the rear view In this case, it can be configured to be inclined in side view.
