JP6711481B2 - Step elimination slope - Google Patents

Description

The present invention relates to a step eliminating slope that is brought into contact with a step surface on a passage.

Steps are provided in various places both outdoors and indoors, which not only is inconvenient for wheelchair users, elderly people, and people with disabilities, but in some cases it may be dangerous. There are also examples. In order to deal with such a situation, various step difference eliminating slopes have been conventionally proposed (for example, refer to Patent Document 1).

Patent Document 1 discloses a step-eliminating block for allowing a person who uses a wheelchair indoors to easily pass through a stepped portion such as a threshold. The block has multiple grooves parallel to the contact surface with the step on the slope of the slope (upper surface of the slope) at equal intervals, and when the wheels of the wheelchair roll on the slope. It is said that it has a non-slip function.

However, in these techniques, there is a problem in that the sloped surface of the step eliminating slope has monotonous irregularities repeated in a side sectional view, and thus the anti-slip performance is not necessarily high. In particular, if the slope is wet due to bad weather such as rain, if the slope is not dry after cleaning, or if the wheel of a wheelchair or the foot or sole of a pedestrian is wet, clean the slope. There is a problem that the wheel of the wheelchair may slip when riding over, or the elderly may slip their legs.

It is a perspective view of the level difference elimination slope which concerns on 2nd Embodiment of this invention. It is a figure which expands and shows the connection part in the β-β line of FIG.

Hereinafter, modes for carrying out the present invention (hereinafter, referred to as “embodiments”) will be described in detail with reference to the accompanying drawings. The same elements are denoted by the same numbers throughout the description of the embodiments.

(First embodiment)
The level difference eliminating slope 1 according to the first embodiment is used by being brought into contact with various level difference surfaces existing on a passage outdoors or indoors. Indoors, for example, it is placed on an upstile at the entrance, a step like a threshold separating the dressing room and the bathroom. Outdoors, for example, it is arranged at a step or the like with a road provided at the entrance of a house or a store. Although the heights of these step portions are various, the step eliminating slope 1 according to the present embodiment can be applied to any height, and the placement location is not selected.

As shown in FIGS. 1 and 2, the level difference eliminating slope 1 contacts the upper surface 20 through which pedestrians such as wheelchairs and the elderly pass, both side surfaces 30 and 30 located at both ends of the upper surface 20, and the step surface D. The main body 10 is constituted by a contact surface 40 that contacts and a bottom surface 50 that contacts the floor F or the like. The height of the step surface D is not particularly limited, but is set to about 10 to 100 mm.

The upper surface 20 is inclined at an angle determined according to the place of arrangement and has a distance in the passing direction. The upper surface 20 is provided with a shallow concave portion 21 extending parallel to the step surface, and a pair of convex portions 22 and 22 extending parallel to the shallow concave portion 21 so as to sandwich the shallow concave portion 21. The details of the shallow concave portion 21 and the pair of convex portions 22 and 22 will be described later.

Further, on the upper surface 20, at least one of the pair of convex portions 22, 22 and the first deep concave portion 23 extending in parallel on the opposite side of the shallow concave portion 21, the shallow concave portion 21, and the pair of convex portions 22, 22 are provided. And a second deep recess 24 extending so as to intersect with each other. In other words, the first deep recessed portion 23 is positioned so that the shallow recessed portion 21 and the pair of protruding portions 22 and 22 that sandwich the shallow recessed portion 21 as one unit are divided into units. These deep recesses are provided to improve drainage of the upper surface 20. Although FIG. 1 and FIG. 2 occupy an example in which there are three first deep recesses 23 and three second deep recesses, the number is not limited to these, and the entire step eliminating slope 1 is not limited to these numbers. It can be appropriately set according to the desired size.

Both side surfaces 30 and 30 are configured to be inclined like the upper surface 20 from the viewpoint of barrier-free. As a result, it is possible to prevent the wheel of the wheelchair and the foot of the pedestrian from colliding against the side surface, and it is possible to access the upper surface 20 not only from the front surface but also from the side surface. A first deep recess 23 extends from the upper surface 20 on both side surfaces 30 and 30 in order to laterally drain the water on the upper surface 20. The extended portion 231 of the first deep recessed portion 23 is formed so that the higher it is, the closer it is to the bottom surface 50, depending on the height of the upper surface 20 due to the inclination.

Next, the details of the shallow concave portion 21 and the pair of convex portions 22 and 22 will be described. As shown in FIG. 2A, first, the upper surface 20 of the main body 10 is partitioned by the first deep recess 23. Unlike the inclination of the upper surface 20, the bottom surface 23a of the first deep recess is formed parallel to the floor F or the like on which the main body 10 is grounded. This is to prevent water on the upper surface 20 from flowing over the shallow concave portion 21 and the pair of convex portions 22, 22 when the upper surface 20 is inclined. In this embodiment, water is drained from the upper surface 20 via the first deep recess 23 and/or the second deep recess 24 intersecting with the first deep recess 23.

On the other hand, the bottom surface 21a of the shallow recessed portion 21 forms an inclination of the upper surface 20 with an inclination angle θ1 as shown by an imaginary line L1 in the figure, which allows smooth passage when a wheelchair or a pedestrian goes up and down. Is possible. The inclination angle θ1 is set to, for example, a maximum of 14 degrees in consideration of the fact that the wheelchair can be pushed to pass through. A pair of convex portions 22 and 22 are provided on both sides of the shallow concave portion 21 so as to sandwich the shallow concave portion 21, and the convex portion 22 on the lower side of the upper surface 20 is the second convex portion 221 and the upper surface 20 is higher. Assuming that the convex portion 22 on the side is the first convex portion 222, the second convex portion 221 sharply rises at an angle θ2 with respect to the bottom surface 21a of the shallow concave portion 21 as shown in an enlarged view in FIG. 2B. The first convex portion 222 is configured to rise gently at an angle θ3 with respect to the bottom surface 21a of the shallow concave portion 21.

In addition, as shown in FIG. 2B, the second convex portion 221 and the first convex portion 222 do not have the same or similar shapes but different shapes. Here, in the present specification, those having the same contour but different sizes are defined as different shapes. More specifically, above the imaginary line L1 connecting the bottom surface 21a of the shallow recess 21, the second protrusion 221 linearly moves upward from the lower side of the upper surface 20 to the apex 221a. It is deeply recessed toward the lower end 21a1 of the bottom surface 21a of the shallow recess 21. On the other hand, the first convex portion 222 is continuous with the first deep concave portion 23 extending in parallel above the first convex portion 222, and the first deep concave portion is above the first convex portion 222. It has a step portion 222c continuous from 23. By forming the step portion 222c, the area of the portion that is not the inclined surface is increased, and by extension, the pedestrian's foot and the installation area of the wheel when the wheelchair is passing can be increased, and an excellent anti-slip effect is achieved. Is possible. Further, by chamfering the step portion 222c with the C surface or the R surface, it is possible to relieve the pain of the foot when passing. The lower side of the first convex portion 222 is smoothly connected by a rising portion 222b connected to the shallow concave portion.

In the first convex portion 222, the rising portion 222b is depressed toward the step portion 222c at the boundary between the step portion 222c and the rising portion 222b, and the rising portion 222b is located above the step portion 222c. The apex 222a (also referred to as a protrusion) is formed, and the first protrusion 222 has a two-stage protrusion structure. The apex 221a of the second convex portion 221 and the apex 222a of the first convex portion 222 are configured to be located on the virtual line L2 parallel to the virtual line L1 throughout the entire section of the upper surface 20.

In this way, by making the combination of the second convex portion 221/shallow concave portion 21/first convex portion 222 as one unit, it is possible to use the wheel of the wheelchair or the foot of the pedestrian, rather than the upper surface where the irregularities are simply repeated. It can be captured with certainty. That is, the second convex portion 221 that is the lower side of the upper surface 20 supports the wheel of the wheelchair and the foot of the pedestrian, and the first convex portion 222 that is the upper side can be gently received together with the shallow concave portion 21 and is easy to pass. At the same time, it has improved anti-slip performance.

Since the first deep recesses 23 are provided on both sides of the unit except for the unit on the lowermost side, as described above, moisture such as rainwater is removed from the upper surface 20, that is, the second projection 221/shallow recess 21/. It is possible to prevent the combination of the first convex portions 222 from flowing out to the surface, and to smoothly drain the water in combination with the second deep concave portions 24 provided in the inclined direction of the upper surface 20. As a whole, a step having an improved anti-slip function. It can be set as the elimination slope 1.

By the way, it is preferable that the main body 10 of the step eliminating slope 1 according to the present invention is made of a soft resin, so that the effect of the above-described configuration can be further exerted. As the soft resin, various elastomers can be adopted, for example, TPS (styrene-based elastomer), TPEE (polyester-based elastomer), TPO (olefin-based elastomer). TPA (polyamide type elastomer), TPU (urethane type elastomer), etc. can be adopted.

Furthermore, it is more preferable that at least a part of the upper surface 20, for example, the shallow concave portion 21 and the pair of convex portions 22 and 22 are textured. When the surface is textured, for example, even when the step-resolving slope 1 is installed indoors and the pedestrian wears slippery socks, the second surface can be more easily caught on the upper surface 20, and The combination of the convex portion 221/the shallow concave portion 21/the first convex portion 222 can synergistically enhance the anti-slip effect.

(Second embodiment)
Next, a second embodiment will be described with reference to FIGS. 3 and 4. In the second embodiment, at least one of the both side surfaces 30, 30 of the step eliminating slope 1 is a cut surface 31, and the plurality of main bodies 10 are connected to each other as follows. The description is omitted because it is the same as the first embodiment except that a plurality of main bodies 10 are connected. Note that FIGS. 3 and 4 show a case where the combination of the second convex portion 221/the shallow concave portion 21/the first convex portion 222 is five rows.

FIG. 3 shows the step eliminating slope 1 corresponding to the case where the step surface is long in the lateral direction. Here, an example in which two main bodies 10a and 10b whose one side surface 30 is cut are connected to each other. Shows. Of course, it is also possible to prepare a product obtained by cutting the both side surfaces 30, 30 and connect three or more main bodies.

When the main bodies 10a and 10b are connected to each other, for example, as shown in FIG. 4, two fastening pins 32 and 32 and a space between the two fastening pins 32 and 32 are provided on the cut surface 31 closer to the contact surface 40, that is, on the higher side. A large hexagon bolt 33 is attached, and two smaller hexagon bolts 34, 34 are attached to the cut surface 31 on the lower side on the opposite side. Although not shown here, a space is provided on the back side of the main bodies 10a, 10b at a predetermined distance from the cut surfaces 31a, 31b, and a large hexagon bolt 33 and a large hexagonal bolt 33 penetrating both cut surfaces 31a, 31b. By tightening the small hexagon bolts 34, 34, the two main bodies 10a, 10b are fastened.

(Effects of the embodiment)
According to the above-described embodiment, the level difference eliminating slope 1 is a combination of the second convex portion 221/shallow concave portion 21/first convex portion 222, and the second convex portion 221 and the first convex portion 222 have different shapes (first shape). Since the second convex portion 221 is steep with respect to the shallow concave portion 21 and the first convex portion 222 is gentle with respect to the shallow concave portion 21, the wheelchair wheel and the pedestrian's foot (bare feet or socks indoors are worn) , It is easy to support (whether wearing shoes outdoors), and a high anti-slip effect can be achieved. Moreover, since the side surface 30 of the main body 10 is also configured to be inclined, a pedestrian such as a wheelchair or an elderly person can easily go up and down not only from the front but also from the left and right side surfaces.

Furthermore, the step-resolving slope 1 is made of a soft resin, or the surface of the second convex portion 221/shallow concave portion 21/first convex portion 222 is textured, whereby the catching effect is further enhanced.

In addition, the level difference eliminating slope 1 is installed outdoors by providing the first deep recess 23 in the horizontal direction having the horizontal bottom surface 23a and the second deep recess 24 in the inclined direction. Also, drainage such as rainwater is smoothly performed, and slippage due to moisture can be prevented. In this respect, the same applies to the case of cleaning.

Although the embodiment has been described above, the present invention is not limited to the specific embodiment and includes various modifications, which is claimed by a person skilled in the art. It is clear from the description of the range. For example, the level difference eliminating slope 1 may be arranged vertically rather than horizontally with respect to the level difference surface, or a means for fixing the level difference eliminating slope to the floor or the like may be added.
