Security doors are generally divided into external opening and internal opening. The direction is divided into: external left opening, external right opening, internal left opening and internal right opening.
Opening to the left means that people face the outdoor door, and the hinge (hinge) is opened to the left.
Open to the right means that people face the door outdoors, and the hinge (hinge) opens to the right.
Opening from the inside to the left means that people face the door opening of the room, and the hinge on the left hand side means opening from the inside to the left.
Opening from the inside to the right means that people face the door indoors, and the hinge on the right hand side means opening from the inside to the right.
The door is open for fire prevention and evacuation. Interior doors can follow the following principles.
First, after the door is opened, try not to occupy the main traffic area. Its purpose is to keep the passage or corridor as unobstructed as possible without being affected by opening the door. So in most cases, the bedroom door is basically open in the direction of the bedroom.
Second, after the door is opened, try not to affect the high-frequency use behavior. For example, when the bathroom door opens inward, it will block the toilet or wash basin. It is recommended to open it outward. Try not to be affected after the kitchen door is opened. If the related operations of the kitchen are opened inward, the above problems will occur, and it is recommended to open outward.
Third, if the doors are all concentrated in a narrow space, it is necessary to consider whether there will be a collision when they are opened at the same time. If so, we need to consider how to avoid this situation. Some drive outward, some drive inward, so that we can avoid each other.
