Abstract

PROBLEM TO BE SOLVED: To prevent the generation of a sprained finger by catching the tip of a toe to a stair-nosing section at the time of ascending on a stair by installing an auxiliary member consisting of a flexible material onto the underside of the stair-nosing section in the stair. SOLUTION: An auxiliary member 14 composed of a flexible material is mounted on the underside of the stair-nosing section 13 of the tread 11 of the stair 10. It is further favorable that the auxiliary member 14 is set up so as to cover the whole of the front-side lower section or front-side whole of the stair-nosing section 13. A silicone rubber, an SBR foamed rubber, an urethane rubber, etc., and a polyethylene foam, a vinyl chloride foam, etc., may be used as the auxiliary member 14. When the auxiliary member 14 is fitted to the tread 11 and a riser 12, epoxy adhesives, a double-sided adhesive tape, etc., may be employed. Accordingly, there is no possibility of a strained finger even when the tip of a toe is dashed against the stair at the time of ascending on the stair 10, and safety is obtained.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a foot-friendly, safe staircase.

[0002]

2. Description of the Related Art Conventionally, in a staircase structure for a house, a nose portion of a tread plate protrudes from a burr plate. Due to the protruding nose, for example, when a person with weak legs climbs the stairs, there is a very high risk of catching his toes.
Therefore, in order to prevent hooking, an auxiliary member having a substantially triangular cross section is attached to the lower side of the nosing portion by contacting the lower surface of the protruding nosing portion and the side surface of the baffle plate.

[0003]

However, in the above-mentioned conventional stairs, hooking can be prevented, but since the auxiliary member attached below the nosing portion is made of a hard material such as a wood material, it is necessary to use a fingertip. There was a fear.

The present invention has been made in view of such circumstances, and an object of the present invention is to provide a safe stair that is gentle to a toe when climbing the stairs.

[0005]

According to the present invention, there is provided a semiconductor device comprising:
The described stairs are provided with an auxiliary member made of a soft material, which prevents a toe from being caught on the nose when climbing, on the lower surface of the nose of the tread plate. The stairs according to claim 2,
The stairs according to claim 1, wherein the auxiliary member also covers a lower part on the front side or the entire front side of the nose.

[0006]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, embodiments of the present invention will be described with reference to the accompanying drawings to provide an understanding of the present invention. Here, FIG. 1 is an enlarged sectional view of a staircase according to an embodiment of the present invention, and FIG. 2 is an enlarged sectional view of a main part of a modification of the staircase. As shown in FIG. 1, a staircase 10 according to an embodiment of the present invention includes two not-shown girder beams (not shown) that are arranged between upper and lower floor beams at a predetermined interval in the horizontal direction so as to face each other. A predetermined pitch P in the vertical direction
Is opened to connect a plurality of treads 11 provided in the horizontal direction and adjacent treads 11 to form a predetermined pitch S in the horizontal direction.
And a plurality of burr plates 12 provided in the vertical direction by opening the opening. Below the nose 13 of the tread plate 11 protruding from the burr plate 12, an auxiliary member 14 for preventing fingertips made of a soft material is provided. It has an attached configuration. The details will be described below.

[0007] The tread 11 and the recess 12 are made of the same material as the conventional one, such as wood, and the structure is the same as the conventional one.
Any material can be used for the auxiliary member 14 as long as the material shows softness. For example, a soft rubber material such as silicone rubber, SBR foam rubber, urethane rubber, or the like is used. It is safer to use a foamed resin such as a polyethylene foam or a vinyl chloride foam. The shape of the auxiliary member 14 is, as shown in FIG.
5 and a substantially triangular shape contacting the upper side surface 16 of the recessed plate 12, and a curved surface 17 is formed on the oblique side. In order to attach the auxiliary member 14 to the tread plate 11 and the squeezing plate 12, a nail or the like cannot be used. Therefore, an adhesive such as an epoxy-based adhesive is used.

When the stairs 10 having such a configuration are used, for example, when a person with weak feet rises, if the toes of the feet accidentally hit the auxiliary member 14, the auxiliary member 14 is made of a soft material. There is little risk of fingering.
Thus, the stairs 10 are gentle and safe stairs to the toes.

In the above embodiment, the indentation plate 12
In order to prevent the lower surface 15 of the nosing portion 13 protruding from the side surface 16 of the snare, the auxiliary member 14
Although the structure is such that only the lower surface 15 of the nose portion 13 is covered, as in the modification shown in FIG. May be improved. In addition, the auxiliary member 14,
Regarding the shape of 14a, the lower surface 1
5 only, the lower surface 15 of the nosing portion 13 and the front surface 18 of the nosing portion 13
Is not particularly limited as long as it can be covered. The lower surface 15 and the front surface 18 can cover the entire surface or a part thereof.

In the present embodiment, the stairs provided with the burr plate 12 have been described. However, in a stair without a burr plate, an auxiliary member having a similar structure can be provided at the same position. Further, as the structure of the stairs, the tread plate 11 and the burr plate 12 have been described as a basic type provided between the slab beams, but one side of the tread plate and / or the burr plate is directly fixed to the side wall of the staircase room. Method,
The present invention can also be applied to a spiral staircase type in which one of the tread and / or the dent plate is fixed to the side wall, and the other is fixed around a central pillar.

[0011]

According to the first and second steps,
The lower surface of the nose of the tread is made of a soft material, and an auxiliary member is provided to prevent the toe from being caught on the nose when ascending.When ascending the stairs, for example, use the toe of the foot as an auxiliary member. Even if it strikes, there is no need to worry about fingering as in the past, and it is safe. Particularly, in the staircase according to the second aspect, the auxiliary member further covers the lower part on the front side or the entire front side of the stair nosing portion, so that it is more secure.
