Description

Technical Field

[0001] The present invention relates to an improvement of a step elimination slope that is installed at a stepped portion of a building such as a threshold or a room entrance to eliminate these steps and facilitate crossing the stepped portion with a wheelchair or a nursing walker.

Background Art

[0002] A wedge-shaped member called a step elimination slope is generally installed at a stepped portion of a building such as a threshold or a room entrance to eliminate the steps and facilitate crossing the stepped portion with a wheelchair or a nursing walker (hereinafter referred to as "wheelchair etc."). As an example of such a step elimination slope, for example, the one shown in Patent Document 1 is known.

Summary of the Invention

Problems to be Solved by the Invention

[0004] When the step elimination slope is installed at the stepped portion of a building, it is generally colored in a color that is not conspicuous even when placed at the stepped portion (for example, brown, a color similar to wood) so as not to damage the indoor atmosphere. However, there have been voices saying that the position of the entrance of the step elimination slope is difficult to understand and that there is anxiety when passing through the step elimination slope. Such problems are particularly prominent in dim places.

[0005] An object of the present invention is to provide a step elimination slope that can easily grasp the position of the entrance of the step elimination slope even when installed in a dim place.

Means for Solving the Problems

[0006] The device described in claim 1 is a step elimination slope 10 having a substantially wedge-shaped longitudinal section in vertical section, which has a back surface 16 in contact with a vertical surface X1 of a corner portion Y of a step X of a building, a running surface 18 that slopes downward from the upper edge of the back surface 16 toward the front end, and a bottom surface 20 in contact with a floor surface F. In the step elimination slope 10, a colored portion 14 having a higher brightness than the running surface 18 is provided along an entrance 18c of the running surface 18.

[0007] The device described in claim 2 is a step elimination slope 10, characterized in that the colored portion 14 is colored yellow.

[0008] The device described in claim 3 is a step elimination slope 10, characterized in that the colored portion 14 is one or a plurality of belt-like bodies provided along the entrance 18c of the running surface 18.

Effect of the Invention

[0009] According to the step elimination slope of this device, since a colored portion having a higher brightness than the running surface is provided along the entrance of the running surface, it becomes easy to grasp the position of the step elimination slope. In particular, when the colored portion is colored yellow, it becomes easier to grasp the position of the step elimination slope even in a dim place.

Mode for Carrying Out the Invention

[0011] Hereinafter, the present invention will be described in detail with reference to FIGS. 1 to 3. The step elimination slope 10 according to the present invention includes a slope main body 12 and a coloring portion 14.

[0012] As shown in FIG. 2, the slope main body 12 has a horizontally long rectangular shape in plan view, and has a back surface 16 in contact with the vertical surface X1 of the corner portion Y of the step X of the building, a running surface 18 that slopes downward from the upper end edge of the back surface 16 toward the front end, and a bottom surface 20 in contact with the floor surface F. Therefore, the longitudinal section of the slope main body 12 is formed as a substantially wedge-shaped member. The slope main body 12 is colored brown so as not to be conspicuous even when the whole is placed in the step X portion so as not to damage the indoor atmosphere when installed in the step X portion of the building.

[0013] The width of the slope main body 12 (the length in the left-right direction in FIG. 2) is set in the range of 60 cm to 80 cm, and the length is appropriately selected according to the frontage of the step X portion (set to 76 cm in this embodiment).

[0014] The inclination angle of the running surface 18 is set in the range of 10° to 20°, and preferably set in the range of 15° ± 2° (set to 14° in this embodiment). When the gradient exceeds 20°, it becomes difficult to get on with a wheelchair. On the other hand, when the gradient is 10° or less, the running surface 18 becomes too long and it becomes difficult to install indoors.

[0015] The running surface 18 is configured in a substantially trapezoidal shape in plan view with the rear end side being narrower than the front end side, and on both the left and right sides thereof, side surfaces 22a and 22b are formed which slope downward from the side edges 18a and 18b of the running surface 18 toward the side ends 12a and 12b of the slope main body 12. The side surfaces 22a and 22b are triangular in plan view.

[0016] A plurality of (four in this embodiment) concave grooves 24 are formed at predetermined intervals on the running surface 18 and the left and right side surfaces 22a and 22b of the slope main body 12, passing through the running surface 18 from the side end 12a of one side surface 22a to the side end 12b of the other side surface 22b.

[0017] At the front end (entrance 18c) of the running surface 18 of the slope body 12, a plurality (three in this embodiment) of colored portions 14 are formed at predetermined intervals along the entrance 18c. Each colored portion 14 is provided to make it easier to grasp the position of the step elimination slope 10, and is formed by painting the surface of the slope body 12 with paint in a strip shape. As the color of the colored portion 14, a color with higher lightness than the running surface 18 is selected. In this embodiment, yellow is selected so as to be conspicuous even in the dark.

[0018] On the running surface 18 of the slope body 12 including the colored portion 14, anti-slip irregularities 26 are formed on the entire surface except for the concave groove 24. In this embodiment, the irregularities 26 are in a diamond pattern and are formed by inclined grooves 28 intersecting each other (see inside the circle in FIG. 2).

[0019] Since the back surface 16 of the slope body 12 is arranged in contact with the vertical surface X1 of the step X, the angle of the back surface 16 with respect to the bottom surface 20 is set to 90°.

[0020] The height of the back surface 16 is set in the range of 1.5 cm to 5 cm, and a height suitable for the height of the step X of the building is selected.

[0021] When using the step elimination slope 10 configured as described above, as shown in FIG. 4, the step elimination slope 10 may be installed at the corner portion Y of the step X.

[0022] Since the running surface 18 of the step elimination slope 10 of this embodiment is provided with the colored portion 14 colored with a color having higher lightness than the running surface 18, the position of the entrance 18c can be easily grasped, and the step elimination slope 10 can be climbed with confidence.

[0023] Moreover, in this embodiment, since the colored portion 14 is colored yellow, the position of the entrance 18c can be easily grasped even in a dim place, and the user can use it with confidence.

[0024] In the above-described embodiment, three colored portions 14 were formed at the entrance 18c of the running surface 18. However, as in the slope for eliminating steps 10 of the second embodiment shown in FIG. 5, only one colored portion 14 may be provided, or although not shown, two or more than four colored portions 14 may be provided.

[0025] Also, the color of the colored portion 14 is not limited to yellow, and any color may be selected as long as it is conspicuous in relation to the color of the slope main body 12. If the colored portion 14 is formed by applying a fluorescent paint, it becomes possible to grasp the position of the slope for eliminating steps 10 as the colored portion 14 emits light in the dark.
