Pivot Door Assembly Vertical Adjustment Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pivot door assemblies lack flexibility and ease of adjustment, making it difficult to align and maintain the pivot door within the door frame, especially when manufacturing tolerances and floor-to-ceiling dimensions vary.
Innovation Solution
The pivot door assembly includes a bottom bracket with a pin and a lower adjustment assembly featuring a pivot member with a ramp, a traveling assembly, and a threaded adjustment rod, allowing for vertical movement of the beam relative to the pivot member, along with an upper adjustment assembly that secures the top bracket to the horizontal jamb, enabling horizontal adjustments and smooth pivoting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional pivot door assemblies are used, then the structure is simple, but the ease of adjustment and alignment is poor
Solution Approach 1:
The pivot door assembly incorporates adjustable components including a movable bottom bracket that can be repositioned along the vertical jamb, and an adjustable beam that can be repositioned along the pivot member. These dynamic adjustment capabilities allow the system to adapt to varying manufacturing tolerances and dimensional variations, improving ease of alignment and operation while maintaining a relatively compact structure.
2Adaptability or versatility
If traditional pivot door assemblies are used, then the device is simple, but the adaptability to dimensional variations is poor
Solution Approach 1:
The assembly allows for parameter changes through adjustable components: the bottom bracket can be positioned at different locations along the vertical jamb, and the beam can be positioned at different locations along the pivot member. This enables the system to accommodate variations in floor-to-ceiling dimensions and manufacturing tolerances by changing the positional parameters of these components, thereby improving adaptability without requiring an overly complex structure.
3Manufacturing precision
If traditional pivot door assemblies are used, then the assembly process is simple, but the precision of alignment is poor
Solution Approach 1:
The pivot door assembly incorporates preliminary adjustment capabilities where the bottom bracket and beam can be pre-positioned and adjusted during assembly to achieve proper alignment. The adjustable design allows for preliminary alignment adjustments to accommodate manufacturing tolerances, thereby improving alignment precision while keeping the assembly process relatively straightforward through the use of standard adjustment mechanisms.

AI summary
A pivot assembly for supporting a pivot door within a door frame includes a bottom bracket and a lower adjustment assembly that includes a pivot member. The pivot member includes a ramp inclined at an angle to a rotation axis, and a traveling assembly positionable along the ramp of the pivot member. The traveling assembly includes a traveling body, a dowel adapted to move along the ramp, and a threaded adjustment rod. The lower adjustment assembly also includes a locking fastener that is adjustable between a locked configuration and an unlocked configuration. In the unlocked configuration, rotation of the adjustment rod causes movement of the traveling assembly vertically relative to the pivot member, thereby permitting a beam of the pivot door to move vertically relative to the pivot member.
