Description

It relates to handrails installed to assist walking and prevent falling.

Handrails are bars and fences that are installed to assist walking and prevent falls.The roles required of handrails are to prevent falls, and to support a comfortable daily life by making walking and movement smoother. That's what it is. A handrail may help you when standing up or going over a step. However, this is for able-bodied people, and for people with physical disabilities, although there are differences depending on the level of disability, there are those who can barely move by holding on to a handrail, and those who cannot move at all without a handrail. be.
Handrails are absolutely essential for people with physical disabilities, even in daily life. The same applies to elderly people with weak legs.

However, there are many places where the handrail is not installed at all, where it is only on the right side or the left side, and where it is cut off in the middle.
In order to compensate for this, there are temporary handrails and standing handrails that can be installed where there are no handrails. The object is large and heavy, and cannot be easily moved.

Occupational Safety and Health Ordinance, (Stepladder) Article 528, 3

Handrails are important for people with physical disabilities, people with physical disabilities, and elderly people with weakened legs, but they are not installed in places where they are not installed, and even if they are installed, they are not on both sides. In many places it is only on one side.
For example, a person with a left hand or left leg is trying to climb stairs. If there is a handrail only on the right side when going up, it may be possible to go up, but when going down, the handrail is only on the left side, making it impossible to go down.
In addition, there are cases where, even though you have struggled to reach the top of the stairs, you cannot climb the last step because it is a landing and the handrail is broken.
This is what actually happened in the dance hall on the second floor, which is the common area of the apartment complex, when I had a physically handicapped friend come to my house on the third floor of the apartment complex.
The same is true when going down, and there are many places where there are no handrails on the platform or on the flat area under the stairs.
The last step, one step can't move forward.
In order to solve these problems, there is a handrail that can be carried by the servants, attendants, and caregivers wherever they want it, can be installed reliably on the right or left side, and can be used with peace of mind. ,is necessary.

Stairs and steps are everywhere, not only in buildings but also in parks and other places where we live.
It would be nice if the handrails were firmly installed so that physically handicapped people and the elderly with weakened legs could move easily. , Since it is going to be moved to a place where it is not installed, it must be something that can be carried by the servant and the attendant or caregiver.
In order to be portable, it must be as small and light as possible.
For that reason, we have to think about making it foldable or assembled.
In addition, it is necessary to have something that is strong and that can be installed reliably.
Considering these factors, the most important thing is how to make sure that it can be installed in places with steps such as stairs. There is another problem in that regard.
Stairs, steps, etc. vary depending on the building and location you visit, and the width, depth (dimensions of the tread), and height (dimensions of the riser) of the stairs and steps are not constant.
If it works in one place but doesn't work in another, it's useless.
A thing that can be installed firmly and reliably in any place you visit (other than rare, special stairs, etc.).
In order to solve it, we can solve it by giving it an expansion and contraction function that can be adjusted according to the site where we visit.

Disabled people, elderly people with weakened legs, and their attendants and caregivers want handrails here and there, whether they are on the right side or the left side. By installing this portable railing where you think, you can't go until now. I can go to places I thought. The possibilities are wide open. I think that the.
I made a prototype and actually used it to get the friend who was unable to climb the last step to go up the landing on the second floor of our house.
The physically handicapped person was full of anxiety and was unable to move, but the caregiver supported the prototype installed on the stairs from below with his left hand and placed his right hand on his buttocks. When I supported it, I was able to rise.
Secure placement of attendants and caregivers and this posture are absolutely necessary to prevent falls.
The caretaker's wife said, "If I have this, I can go to that inn at that hot spring."
“For 10 years after my husband became disabled, I had been wondering if there was something like this.
“This makes me happy that people with physical disabilities and people with disabilities can see the light, but I am also a caregiver and have a bright future. "
It is a very important and necessary item not only for the physically handicapped, those requiring nursing care, and the elderly with weakened legs, but also for their attendants and caregivers.

A perspective view of a handrail spanning the third and fourth steps of a staircase. The perspective view which installed the handrail over the 3rd and 4th steps of the stairs in the stairs. The perspective view which installed the handrail over the 2nd and 3rd steps of the stairs in the stairs. The side view when the center part of the handrail which straddles 3rd and 4th steps is installed in the height of 75 cm from a tread surface in the stairs of the kind 4 of the Building Standards Law Enforcement Ordinance. (Example 1) FIG. 4 is a side view showing the installable height and position of the handrail when the handrail extending over the 3rd and 4th steps of the same staircase in FIG. (Example 1) The side view when the center part of the handrail which spans the 2nd and 3rd steps of stairs is installed in the height of 80 cm from a tread surface in the stairs of the kind 4 of the Building Standards Law Enforcement Ordinance. (Example 1) FIG. 6 is a side view showing the installable height and position of the handrail when the handrail extending over the 2nd and 3rd steps of the same staircase in FIG. (Example 1)

In order to install it firmly and reliably on stairs, steps, slopes, and flat areas, it is of course necessary to have an extension and adjustment function that can be adjusted according to the site you visit. However, it is most important to be able to use the railing safely.
For that reason, how to install the handrail that can be carried.
Ordinance on Industrial Safety and Health, (Stepladder) Article 528, 3. The angle between the legs and the horizontal plane shall be 75 degrees or less, and for foldable ones, the angle between the legs and the horizontal plane shall be securely maintained. Be prepared with metal fittings.
Safety standards for each work, work using stepladders, etc., 11. Ladders, (2) Use non-slip items and have other workers hold the legs. (3) As a general rule, the angle should be 75 degrees or less with respect to the plane.
In order to materialize such things, in order to ensure that the angle between the legs and the horizontal plane is kept at 75 degrees, it can be installed anywhere such as stairs, flat ground, etc. If so, it can be realized by attaching a level to the 75-degree structure and the 75-degree portion.

Just as the speed of walking on flat ground with a cane differs depending on the degree of physical disability or the degree of weakness of the elderly, how to hold the handrail, how to apply force, and how to apply weight. There are various ways.
So, I made two prototypes.

For people with a little disability, elderly people with weak legs, etc., put a lot of force on the handrail and lift your own weight as if you were doing a pull-up. The perspective views of FIGS. 1 and 2 show an object straddling four stages.

People with mild disabilities, elderly people with weakened legs, etc., who do not need to apply too much force to the handrails, and who only need to hold them lightly to maintain their balance, are recommended for those who need to use the handrails on stairs and steps. An object straddling two or three stages is represented by the perspective view of FIG.

The table below is the Building Standard Law Enforcement Ordinance, Article 3, the dimensions of the stairs. is.

In the table above, with regard to stairs in houses of type 5, handrails, etc., have already been installed in the homes of people with physical disabilities. This is a specific example of installation at a place visited by an elderly person, etc., when they go out from home.
4, 5, 6, and 7 are stairs of type 4 in the table above.
The above-mentioned shared stairs in our apartment, where the last step could not be climbed, is a staircase of this type 4 with a riser dimension of 22 cm or less and a tread dimension of 21 cm or more.
This is the steepest staircase other than the staircases in houses of type 5 in the table above.
This slope and the staircase with a gentler slope than this slope can be installed without fail.
This means that it can be installed reliably in all facilities other than residences specified by the Building Standards Act.
The details of main uses and scales are nursing homes, universities, libraries, museums, hospitals, clinics, hotels, inns, gymnasiums, department stores, markets, and other merchandise stores with an area of 1,500 square meters or less.
The dimensions in the figure are the dimensions of the prototype that was made, and can be made in any way by setting the size of the main body, expansion and contraction, and the length of the adjustment part.
FIG. 4 is a side view of a handrail that spans the 3rd and 4th steps of the stairs and is installed at a height of 75 cm from the tread surface of the central part of the handrail at each location of the stairs.
Fig. 5 shows the possible height and position of the handrail when the object in Fig. 4 is installed on each tread on the same stair, with both the upper and lower expansion parts of the staircase expanded and contracted to the maximum. is a side view. The height of the handrail from the tread is between 70 cm and 85 cm, and can be installed at a desired height for each individual.
FIG. 6 is a side view of a handrail placed over 2nd and 3rd steps at a height of 80 cm from the tread surface of the central part of the handrail at each location of the stairs.
Fig. 7 shows the possible height and position of the handrail when the object in Fig. 6 is installed on each tread by maximizing the expansion and contraction of both the upper and lower expansion parts of the stairs on the same staircase. is a side view. The height of the handrail from the tread is between 67 cm and 95 cm, and can be installed at the height desired by each individual.
