Pivot doors are one of the most impressive details of architecture.
To ensure this visual and functional impact, the hinge position must be determined correctly.
Where we place the pivot hinge determines the aesthetics of the door and the passage width.
It also directly affects the ergonomics of use and the life of the door.
Factors Affecting Passage Distance
- Frame thickness: The frame to which we mount the door consumes a certain thickness from the wall cavity.
Therefore, when calculating the net passage distance, the frame thickness must be subtracted. - Door thickness: The thickness of the leaf itself also takes a share from the passage area when opening.
- Section behind the pivot point: The rear part after the hinge narrows the theoretical passage width.
- Hinge position: The closer the pivot hinge is to the corner, the wider the passage becomes.
However, getting too close to the corner creates technical problems such as profile collision.
Pivot Hinge Positioning
FritsJurgens’ standard pivot hinge systems are among the highest quality solutions.
In these systems, we can place the pivot point up to 70 mm to the corner.
We can reduce this distance even further with FritsJurgens’ 40 mm hinges.
However, approaching the corner in entrance doors increases the risk of profile collision.
The profile type and construction detail determine this decision.
Hinge Quality and Installation
As important as the quality of the hinge is, it is necessary to install it correctly.
High load-bearing hinges such as FritsJurgens provide assurance for heavy doors.
The floor and superstructure on which we install it must be solid.
Otherwise, the load-bearing capacity of the hinge becomes irrelevant.
It is also important to design the construction of the door correctly.
It is essential that the body is resistant to flexing and bending in large dimensions.
Door Dimensions and Parameters
- Leaf Width: As the door widens, the pivot point needs to be taken more to the center.
Thus, the aesthetic ratio is preserved and the leaf works in a balanced way. - Leaf Weight: The pivot position should be determined more carefully for heavy leaves.
Thus, the weight distribution is correct. - Height: Height is the third parameter after width and weight.
As the height increases, the rigidity of the construction becomes more important.
Recommended Ratios in Practice
- Doors with a width of 1.20–1.40 m: The pivot point is usually positioned close to the center.
- Doors of 1.60 m and above: The pivot point is taken to the center.
This provides both aesthetics and stability. - Narrow interior pivot doors (80–100 cm): The pivot is placed 60–100 mm from the inside.
From an aesthetic point of view, a ratio of 1/6 – 1/8 creates a balanced image.
This ratio is the relationship between the door width and the pivot distance.
The pivot hinge position is not only an engineering detail but also a design decision. To correctly calculate the passage distance, all parameters such as frame thickness, door thickness, hinge back clearance, and door dimensions must be evaluated together. The right hinge selection, solid construction, and perfect installation are the cornerstones of this decision.
