Purchase safety furniture standard manual

Those who can meet the specific needs of the user are beneficial to the user's health. There are no hidden dangers to human body poisoning and injury. In the production process, there are strict dimensional standards. Furniture designed according to ergonomic principles should have the following characteristics:

1) Furniture materials tend to be natural and do not contain harmful substances.

2) Green products are ergonomically designed and people-oriented. They not only pay attention to the physiological conditions of the human body under static conditions, but also study the physiological conditions of the human body under dynamic conditions. In the normal use and occasional misuse, people will not have adverse effects and injuries.

3) Design and production as much as possible to extend the product life cycle, make it more durable and reduce energy consumption in reprocessing.

4) The designed product has a high grade and should have cultural heritage and scientific and technological content.

These furniture must be conducive to the health of the human body. For the height of tables and chairs, the country has established standards. Among them, the height standard of table furniture is 700-760mm, and four specifications; the seat height of the chair-stool is 400-440mm. In addition, it is also stipulated that tables and chairs are used with standard sizes, and the height difference between tables and chairs should be controlled within the range of 280-320 mm.

The correct height of the table and chair should enable the person to maintain two basic vertical positions while sitting: First, when the two feet are placed on the ground, the thigh and the lower leg can be substantially vertical, and the front edge of the seat cannot form an oppression on the lower plane of the thigh. The second is that when the arms are naturally suspended, the upper arm and the lower arm are substantially perpendicular. At this time, the height of the tabletop should be just in contact with the lower plane of the lower arm, so that the person can maintain the correct posture and writing posture. If the height of the table and chairs is unreasonably matched, it will directly affect people's sitting posture, which is detrimental to the user's health. For this reason, the space under the writing table top is not less than 580mm, and the space width is not less than 520mm.

As for the sofa size, the front width of the sofa seat should not be less than 580mm, the depth of the seat surface should be in the range of 480-600mm, and the height of the seat surface should be in the range of 360-420mm. The height of the hanging closet is 40-60mm from the upper edge of the clothes rail to the top of the cabinet, which is a waste of space. If it is small, it will not fit into the hanger. The distance from the bottom of the clothes rail to the bottom of the cabinet should not be less than 1350mm. The depth of the wardrobe mainly considers the shoulder width factor of the person, which is generally 600mm, and should not be less than 500mm, otherwise only the oblique hanging can close the door.
