Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a health stair tread for indoor use, which is useful for preventing slipping and promoting health at the same time.

[Prior art and its problems]

Conventional indoor stair treads generally have smooth upper surfaces, which poses a risk of slipping and falling accidents, especially for young children and the elderly.

On the other hand, green bamboo and health pine are known as health appliances that stimulate the soles of the feet. The intended health-improving effects of these products can only be achieved by using them continuously on a daily basis, but users may find it troublesome to use them continuously or forget to use them, so they stop using them. It has the disadvantage that it tends to be hyperactive, making it difficult to expect much of the health-improving effect mentioned above.

[Means for solving problems]

The present invention has a recessed part on the top of the stair tread that is in contact with the sole of a standard adult's foot, from the base of the big toe to the rear end of the arch, when a stair user goes up or down the stairs. By providing the protrusions, not only does the stair tread have a non-slip effect, but also the protrusions allow the user who goes up and down the stairs on a daily basis to touch the pot on the sole of his/her foot. The problem of the conventional stair treads and health equipment can be solved all at once by allowing the user to receive continuous stimulation and improve health.

[Structure of the idea]

The present invention has a stair tread with a standard depth, on the upper surface of the stair tread, from its front edge toward the rear in the depth direction, within a range of approximately 5/8 of the stair tread's depth.
The feature is that a plurality of protrusions are provided along the width direction so that the line connecting the vertices of each protrusion forms an upwardly protruding line that is higher at the middle and lower at both sides when viewed from the side. It is a healthy stair tread.

Hereinafter, the embodiment will be explained in more detail based on the drawings.

1, 2, 3, and 4 are plan views of an embodiment of the health stair tread of the present invention, respectively;
2 is a side view seen from the direction of arrow A, a sectional view taken along a chain line - of the health stair tread shown in FIG. 1, and a perspective view of a staircase using the health stair tread of the present invention.

In the figure, 1 is the health stair tread of the present invention, and its depth L is about 240 mm, which is the same as the standard depth of a general stair tread. In particular, as can be seen from the side view of FIG. 2, on the upper surface of the flat plate part 2, from the front edge 5 toward the rear, there is an area approximately 5/8 (l ₁ ) of the depth L of the stair tread 1.
A plurality of protrusions 3 are arranged along the width direction so that a line (not shown) connecting the vertices of each protrusion 4 forms an arc that is higher at the middle and lower at both sides when viewed from the side. is provided.

Specifically, the range of approximately 5/8 (l ₁ ) of the depth L of the stair tread 1, which is the range in which the plurality of protrusions 3 are provided, is specifically the depth L of the stair tread 1.
is about 240 mm, so l ₁ is in the range of about 150 mm. Further, the length l ₁ =approximately 150 mm corresponds approximately to the distance from the base of the big toe of the sole of a standard adult's foot to the rearmost end of the arch of the foot.

When a stair user climbs up a flight of stairs, he or she usually steps on the stair tread with the sole of the foot, from the base of the big toe to the end of the arch, leaving the heel outside of the stair tread. At that time, the concave part of the user's sole from the base of the big toe to the rear end of the arch will just press down on the plurality of protrusions 3, and the user of the stairs will In the same way, when descending the stairs, a considerable portion of the user's sole from the base of the big toe to the rearmost end of the arch of the foot is pressed against the plurality of ridges 3.
Therefore, each time a stair user goes up or down the stairs, the user must check the area of the foot that exists in the concave area from the base of the big toe to the end of the arch (especially near the center of the arch). The pot on the back is stimulated under ideal conditions and has a remarkable health-promoting effect.

Furthermore, it goes without saying that the plurality of protrusions 3 also serve to prevent the stair tread 1 from slipping.

In addition, in this example, as a preferable configuration for stimulating the soles of the feet of stairs users,
The height h ₂ of the arc-shaped apex projecting upward is approximately 8 mm from the top surface of the flat plate portion 2, and the distance l ₂ between each protrusion 4, 4... is approximately 8 mm.
The cross-sectional shape of the 12 mm multiple protrusions 3 is a wavy shape consisting of alternately continuous semicircular peaks 4' and troughs 4''.In particular, the spacing between the protrusions 4, 4... l ₃
The reason for setting the distance to approximately 12 mm is that it is a well-established theory that the preferred distance between the pots for adults in acupressure, etc. corresponds to the distance between the first and second joints of the thumb of that person's hand. The first and second joints of the thumb of the hand
Considering the fact that the distance between the joints is generally about 24 mm, the use by children, and the anti-slip function, we selected about 12 mm, which is half of the above-mentioned about 24 mm.

In addition, in this embodiment, the width D of the stair tread 1 is 800 to 1000 mm, and the plurality of protrusions 3 are
Width d ₁ : 720 to 920 mm, Width d 2 of the ears 2' of the flat plate part 2 of the stair tread ₁ : 40 mm, Flat plate part 2 from the rear end of the plurality of protrusions 3 to the rear end of the stair tread 1 The depth of the top surface L ₂ : 90 mm, the thickness of the stair tread 1 h ₁ : 30 mm, and the height of the protrusion 4 h ₃ : 5 mm. A matching recess 6 is provided.

In addition, in this embodiment, a plurality of protrusions 3
Although the illustration shows an example in which the whole of the plurality of protrusions 3 is formed integrally with the flat plate part 2 of the stair tread 1, the whole of the plurality of protrusions 3 is formed separately from the flat plate part 2 of the stair tread 1, and is made of rubber or plastic. Other suitable materials, and
It may be made of a material with appropriate strength and fixed to the flat plate portion 2 by adhesive or other appropriate means.

It should be noted that the technical scope of the present invention should be determined based on the statement in the first claim of the utility model registration, and is not limited to the above-mentioned embodiments.

Therefore, for example, the cross-sectional shape of the plurality of protrusions is not limited to the wavy shape consisting of alternately continuous semicircular peaks and troughs as in the embodiment, but can also be formed by alternately continuous trapezoidal peaks and troughs. Various modifications are possible, such as a wave shape consisting of, and all of these modifications fall within the technical scope of the present invention as long as they achieve the intended effects of the present invention.

[Effect of idea]

As described above, the healthy stair tread of the present invention is designed to support the stair tread on the top surface of the stair tread when a stair user goes up or down the stairs. By providing multiple protrusions of a predetermined size and shape at the position where the recessed part comes into contact, it not only provides a non-slip effect, but also makes it suitable for daily use when going up and down stairs. The plurality of protrusions provide continuous stimulation to the soles of the feet of the stair users, resulting in a significant health-improving effect on the stair users.
