Question

Почему дверные ручки устанавливают вдали от петель на которое вешают дверь

Answer 1

Потому что двери основаны на принципе рычага. Чем дальше ручка от точки опоры (в данном случае от петель), тем меньшую силу нужно приложить, чтобы открыть дверь.

Answer 2

Why are door handles installed away from the hinges?

Door handles are typically installed away from the hinges on which the door is hung. This placement is based on several practical and ergonomic considerations.

1. Ease of Use: Placing the door handle away from the hinges allows for easier and more comfortable operation of the door. When the handle is located closer to the edge opposite the hinges, it provides better leverage for opening and closing the door. This design makes it more convenient for people to grasp and manipulate the handle, reducing strain on the hand and wrist.

2. Clearance: Placing the door handle away from the hinges ensures that there is enough clearance for the door to swing open without obstruction. If the handle were located too close to the hinges, it could interfere with the door's movement and limit the range of motion. By positioning the handle away from the hinges, the door can open and close freely without any hindrance.

3. Aesthetics: Another reason for installing door handles away from the hinges is for aesthetic purposes. Placing the handle on the side opposite the hinges creates a more balanced and visually pleasing appearance. It allows for a symmetrical design, especially when considering the placement of other elements on the door, such as locks or decorative hardware.

It's important to note that while these reasons explain the general practice of installing door handles away from the hinges, there may be variations and exceptions depending on specific door designs, cultural preferences, or functional requirements.
