Abstract

A multidirectional bent handrail stand column, which is placed in a subway and is a handrail used by multiple persons jointly. The multidirectional bent handrail stand column is bent and cannot be exclusively occupied, and can not only ensure that the needs of passengers who have not no seats and need to hold the handrail are not affected, but also save materials. Therefore, the handrail can play a more full role, reduce the danger of taking the subway, and solve the problem that one person exclusively occupies the handrail while other persons have no place to hold. The bent handrail is more good-looking, practical and space-saving.

Description

Multi-directional bending handrail post

Technical field

The invention relates to a multi-directional curved handrail post, in particular to a subway post that circulates and rises in a 90° direction. The main process is to perform partial bending treatment on the original metal post. The main purpose is to provide people who have no seats in the subway. Public environmental facilities and equipment and processing engineering technology fields.

Background technique

The existing subway handrail facilities are mainly straight column handrails. The disadvantages are: there is always a phenomenon in which one person alone occupies the armrest and leans on it. This phenomenon makes 1. other people have no place to support and cannot play the role of the armrest well; 2. a large amount of armrests are required and a lot of materials are consumed. , It is a bit wasteful to a certain extent; 3. It is not beautiful and has a certain degree of danger. Other people without armrests can only lean on or hold on to other places, and some even rely on subway doors, which is very dangerous.

Summary of the invention

The purpose of the present invention is to provide a handrail placed in the subway for common use by multiple people, and through the change and improvement of the shape design, the unreasonable use of the original column is improved. It not only reduces the bad use of the original passengers relying on the occupied columns, but also increases the use opportunities for passengers who need handrails, saves materials to the greatest extent, makes the handrails more effective, and reduces the danger of taking the subway.

In order to achieve the above purpose, the present design provides a multi-directional curved handrail post, which is characterized by comprising a curved body and a column foot at the bottom. The curved body is provided with four curved parts in sequence from top to bottom; the curved body The positions are separated by 90 degrees, and the four curved positions surround 360 degrees clockwise or counterclockwise.

The handrail of the present invention has four bends protruding outwards, and they are separated by 90 degrees from the first bend to the last bend. The main function of the four corners is for people to grasp and rotate by 90 degrees. It will be uncomfortable for a person to lean on it. This can avoid the situation where one person occupies the armrest exclusively and maximize the function of the armrest. This curved armrest does not take up space and is more beautiful in appearance.

The advantages of this patent are:

1. It can be used by multiple people, which increases the use opportunities to a certain extent;

2. The bending amplitude is not large, which saves space;

3. Reduce the danger of taking the subway and provide convenience for passengers;

4. The armrest itself has a certain sense of design, and looks more attractive from the appearance;

5. Less process and cost reduction.

Detailed ways

In order to make the present invention more comprehensible, preferred embodiments are described in detail below in conjunction with the accompanying drawings.

Example

This example is a multi-directional bending handrail post. The manufacturing process is bending and polishing; the material used is metal material (aluminum alloy or stainless steel welding).

The production process of the original iron mold: The first step is to prepare the aluminum profile mold, and extrude a cylindrical aluminum profile with a length of 2200mm and a radius of 20mm as the main body 1 of the entire handrail; the second step is to bend the aluminum profile , Bend the aluminum profile pillar at 350mm away from the top of the column to form the bending part 3. The bending start point and the end point are 200mm apart, and the second bending is performed at a place 150mm below the first bending end point to form the bending part 4. The start point and end point of the second bend are 200mm together, 90 degrees apart from the first bend, and the third bend is 150mm down from the end point of the second bend to form bend 5, the third bend The start point and the end point are 200mm together, and the three bends are 90 degrees apart from the second bend. The fourth bend is 150mm below the end point of the third bend to form the bend part 6, the fourth bend 90 degrees apart from the third bend. The third step is to install the column feet. The fourth step is to polish and spray paint to finely treat the handrails; the fifth step is to connect the column feet 2 to the subway.

Claims
