Description

The present invention relates to stairs that improve safety when going up and down by making step nosings easier to recognize.

BACKGROUND ART Conventionally, in order to improve safety when going up and down stairs, proposals have been made to increase the visibility of stair nosings and make it easier to check the difference in level of stairs (see, for example, Patent Document 1 and Patent Document 2). Patent Document 1 proposes a step nosing in which a plurality of grooves extending in the width direction of the stairs are formed, and a bright plate is embedded and fixed inside one of these grooves. According to this, even in cases of insufficient illumination such as in a dark place or at twilight, it is easy to confirm the position of the stair nosing, making it easy to recognize stair steps.

In addition, in Patent Document 2, by adhesively fixing a colored identification tape having protrusions on the surface to a groove provided in the stair nosing, the position of the stair nosing can be identified regardless of the height of the line of sight through the diffuse reflection of external light by the protrusions. This makes it easier to recognize stair steps.

However, since the above-mentioned conventional technology makes it easy to recognize the nosing by light and shape, there is a risk of dazzling due to reflected light. Furthermore, in cases where the user has color blindness, which makes it difficult to recognize colors, the user may not be able to sufficiently recognize colored identification tapes and may have difficulty recognizing differences in stair steps.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a staircase in which the position of the stair nosing can be easily recognized and the difference in stair steps can be easily recognized without depending on the color or shape.

The stairway of the present invention is a stairway in which a stair nosing display part that is visible to pedestrians is formed on the upper surface of the stair nosing formed along the tip edge of the tread plate, and the stair nosing display part is responsive to changes in viewing position. It is characterized by being a lenticular shape in which two or more types of patterns can be viewed alternately.

You can increase your sexuality. The term "optical illusion design" as used herein refers to a design that causes pedestrians to perceive a pattern as a three-dimensional object through an optical illusion, or to make pedestrians perceive a pattern that has not actually changed as if it were changing. .

According to the stairs of the present invention, the step nosing display parts are arranged at intervals of 600 mm or less in the width direction of the stairs, so that they can easily be seen by pedestrians and make them recognize the steps of the stairs.

According to the staircase of the present invention, since the surface of the nosing display part is provided with a transparent protective covering material, it is possible to suppress the lenticular from being soiled, and the durability of the nosing display part can be increased.

According to the staircase of the present invention, the nosing display part and the anti-slip part are arranged alternately along the width direction of the stair nosing, so that by directing attention to the nosing display part, the stair step difference can be recognized. It is possible to improve the safety of walking on stairs, and also to prevent slipping and falling on the stairs. Since the step nosing display part and the anti-slip part are fitted and fixed in the base groove of the same cross-sectional shape, by forming one long base groove in the step nosing, the step nosing display part and the non-slip part are fixed. It is possible to improve the workability.

According to the staircase of the present invention, at least one of the patterns includes two colors with different brightness, so the pattern is clearly recognized due to the difference in brightness, and changes in the lenticular pattern and The change in pattern caused by the optical illusion becomes clearer and attention is directed to the step nosing display, making it possible to recognize the difference in stair steps and improve the safety of walking on stairs.

In the staircase of the present invention, at least one of the patterns is a pattern including two complementary colors, so the pattern is clearly recognized due to the contrast between the two colors, and the lenticular pattern Changes in patterns and changes in patterns caused by optical illusions become clearer, and attention is directed to the stair nosing display, making it possible to recognize the difference in stair steps and improve the safety of walking on stairs.

FIG. 3 is a cross-sectional view illustrating the configuration of a nosing display section. FIG. 3 is a diagram illustrating the form of a lenticular image. FIG. 3 is a sectional view illustrating a state in which the anti-slip portion is housed in the base groove.

Hereinafter, an embodiment of the staircase 1 of the present invention will be described with reference to FIGS. 1 to 6. The stairs 1 are, for example, stairs 1 made of steel and used in accommodation facilities or apartment complexes. Note that the staircase 1 is not limited to this, and may be a staircase 1 installed in a public facility or an outdoor road, or may be a staircase 1 installed in a detached house. Moreover, the stairs 1 are not limited to a steel structure, and may be stairs 1 of other forms such as an RC structure or a wooden structure.

As shown in FIG. 1, the staircase 1 is a straight staircase formed from steps 2 and risers 3 supported by non-illustrated beams. Note that the staircase 1 is not limited to a straight staircase, and may be a staircase of other shapes such as a round staircase, a winding staircase, or a turning staircase. Further, the riser board 3 is not essential, and a see-through staircase with a gap between the upper and lower step boards 2 may be used.

As shown in FIG. 2, a step nosing 4 is formed along the leading edge of the step board 2. As shown in FIG. A groove metal fitting 5 bent into a groove shape is fixed to the step nosing 4, and forms a base groove 6 opening upward along the width direction of the stairs 1. A nosing display section 7 and a non-slip section 8 are housed and fixed in the base groove 6. The groove fitting 5 has a groove main body 51 that is bent to form the base groove 6, and a hanging portion 52 that hangs down from the side edge of the groove main body 51 and covers the upper end of the riser 3. The groove fittings 5 are made of steel such as stainless steel or aluminum, and are fixed to the nosings 4 of all the step boards 2 of the stairs 1 over the entire width of the stairs 1. The nosing display parts 7 and the anti-slip parts 8 housed in the base groove 6 are arranged alternately, and are arranged on the upper surface of the nosing 4 along the width direction of the stairs 1.

The anti-slip part 8, which is stored in the part of the base groove 6 where the step nosing display part 7 is not provided, has a flat plate shape that can be inserted into the base groove 6, and has three grooves 81 on the top surface along the width direction of the stairs 1. is formed. The anti-slip portion 8 is made of resin such as polyvinyl chloride, and is colored in a different color from the upper surface of the step board 2. Note that the top surface shape of the anti-slip portion 8 is not limited to the three grooves 81, and for example, although not shown, it may be configured to have a large number of protrusions in an uneven shape so that it can function as an anti-slip. good. The anti-slip part 8 has a dimension of 40 mm in the depth direction of the stairs 1, is formed long in the width direction of the stairs 1, and is housed between adjacent stair nosing display parts 7.

As shown in FIG. 3, the nosing display section 7 includes a flat lenticule 71 and a protective covering material 72 that covers and protects the upper surface of the lenticular 71. The nosing display part 7 is fixed to the base groove 6 by, for example, adhesive, and its dimensions are, for example, a rectangle of 100 mm in the width direction of the stairs 1 and 40 mm in the depth direction of the stairs 1. A plurality of step nosing display sections 7 are housed in the base groove 6 at intervals of 600 mm, and a non-slip section 8 is housed between the step nosing display sections 7.

As shown in FIG. 4, the lenticular lens 71 includes, for example, a sheet-shaped lenticular lens 73 in which a large number of very small semicylindrical convex lenses are lined up on the upper surface, and a lenticular image 74 pasted on the lower surface of the lenticular lens 73. It consists of The lenticular lens 73 is made of resin such as transparent acrylic resin, and the lenticular image 74 is, for example, an image obtained by cutting two kinds of patterns 74a and 74b into long thin strips and arranging them alternately and combining them, as shown in FIG. When viewed through the screen, two types of patterns 74a and 74b are visible that change alternately depending on the viewing angle. Note that the lenticular lens 73 is not limited to one that allows two types of patterns 74a and 74b to be viewed alternately, but may be configured to allow three or more types of patterns to be viewed depending on the viewing angle. Further, the lenticular lens 73 is preferably arranged so that the width direction of the stairs 1 and the length direction of the semi-cylindrical convex lens are parallel to each other. The pattern is difficult to change, and the pattern changes easily depending on the vertical movement of the pedestrian or the progress of the pedestrian.

The protective covering material 72 is a flat sheet made of a transparent synthetic resin material or a glassy material, and covers the upper surface of the lenticule 71 to increase durability. In addition, in order to prevent the visible pattern from changing due to refraction of visible light transmitted through the protective covering material 72, the protective covering material 72 is formed in a simple flat plate shape, and has a shape that does not follow the unevenness of the lenticular lens 73. It is preferable that

At least one of the two types of patterns 74a and 74b displayed by the lenticular 71 of the nosing display section 7 is an optical illusion design. Optical illusion design is, for example, a design in which a pattern that is actually stationary is perceived as moving due to the illusion. Optical illusion designs are not limited to these, and include other well-known optical illusion designs, such as optical illusion designs in which a two-dimensional pattern appears to be a three-dimensional shape through illusion, and optical illusion designs in which a pattern appears larger than it really is. Also good. Both of the two types of patterns 74a and 74b may each have an optical illusion design. It should be noted that optical illusion design differs from color illusions, which create visual illusions depending on the hue of the pattern, in that the slope of the line, the angle, the size of the object, or the position of the object, depending on the shape of the pattern, differs from the physical reality. Preferably, the design uses a geometric illusion that is perceived differently. By using an optical illusion design pattern that uses a geometric illusion that does not depend on hue, the nosing display section 7 can be effectively made noticeable even to pedestrians with color blindness who have difficulty understanding colors.

In this way, the stair nosing display section 7 displays the two types of patterns 74a and 74b by the lenticular 71, so that the pattern changes depending on the vertical movement of the pedestrian as he walks or the angle of his line of sight as he approaches the stairs 1. Since the position of stair nosing 4 of stair 1 is displayed by simply using color or shape, the addition of elements of pattern change and movement helps pedestrians pay attention to the position of stair nosing 4. This makes it easier to draw, for example, even if you have tired eyes or have poor vision, you can easily grasp the difference in one step of a staircase, and it is possible to prevent falls when walking one staircase. In particular, even pedestrians with color blindness, who have difficulty grasping colors, can easily perceive changes in the patterns and movements of the stair nosing display section 7, so they can draw their attention to the stair nosing display section 7, thereby increasing the safety of walking on one staircase. can be increased. Since the two types of patterns 74a and 74b displayed by the lenticular 71 are optical illusion designs, the patterns appear to move or appear to have a three-dimensional shape due to the optical illusion, so pay more attention to the nosing display section 7. This can improve the safety of walking up the stairs.

Each pattern 74a, 74b is formed from two or more colors, and two of the colors forming the patterns 74a, 74b have different lightness. Further, it is preferable that the two colors forming the patterns 74a and 74b are complementary to each other. Specifically, the patterns 74a and 74b are composed of only two colors, and these two colors are complementary colors such as "red" and "green" or "yellow" and "purple"; It is preferable that the difference in color brightness is 3.0 or more. Note that the colors that make up the patterns 74a and 74b are not limited to complementary colors, and may also be achromatic colors; however, when the colors that make up the patterns 74a and 74b are achromatic colors, Or, even if the colors are chromatic, when the hues are close and the saturation is low, it is preferable that the difference in brightness is larger, and it is preferable that the difference in brightness is, for example, 8.0 or more.

As described above, the two types of patterns 74a and 74b of the optical illusion design displayed on the nosing display section 7 are made of two colors with different brightness, and the two colors are in a complementary color relationship, so that the patterns are visible to pedestrians. Changes in the pattern of the lenticular 71 according to the movement of the pedestrian and changes in the pattern due to optical illusions can be more clearly recognized, and attention is directed to the step nosing display section 7, so that the change in the pattern of the lenticular 71 according to the movement of the pedestrian can be more clearly recognized. The safety of walking up the stairs can be improved by making the person clearly aware of the situation.

It goes without saying that the embodiments of the present invention are not limited to the above-described embodiments, and can be modified as appropriate without departing from the scope of the idea of the present invention.

The staircase 1 according to the present invention can be suitably used as a staircase 1 that can improve the safety of walking on the staircase 1, for example, as a staircase 1 of a facility used by an unspecified number of people.
