Sliding Door Anti-Jamming Mechanism for Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Sliding doors with idle wheels fixed to a vertical wall are prone to disengagement due to violent operation, doorstops can facilitate release, and are sensitive to floor irregularities, leading to instability and potential jamming.
Innovation Solution
A sliding door system featuring a top profile with adjustable idle wheels and an anti-releasing component, including a lever mechanism, to securely engage with the door and a pivotable component for handling angle adjustments, along with shock-absorbing devices to stabilize the door at extreme positions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the door is suspended on idle wheels fixed to a vertical wall, then the door can slide between extreme positions, but the door may disengage from the idle wheels when run with violence
Solution Approach 1:
The anti-releasing component with lever is pre-configured to engage with the top profile before violent operation occurs. The lever is positioned to automatically contact and secure the top profile, creating a preliminary restraining force that prevents disengagement when the door is operated violently
Solution Approach 2:
The anti-releasing component acts as an intermediary between the idle wheels and the top profile. When the door experiences violent movement, the lever of the anti-releasing component engages with the top profile, providing an additional securing mechanism that prevents direct disengagement from the idle wheels
2Ease of operation
If doorstops are fixed to the door, then the door can be stopped at end limits, but the doorstops can facilitate release of the door from idle wheels
Solution Approach 1:
The anti-releasing component serves as an intermediary that secures the top profile to the support device structure. This intermediary connection prevents the doorstops from facilitating release, as the top profile is already secured by the lever engagement with the support guide or frame element
3Ease of operation
If sliding means are provided at lower ends of the door, then the door can slide freely on the floor, but the sliding means are sensitive to floor irregularities and facilitate release
Solution Approach 1:
The anti-releasing component with lever provides beforehand cushioning by being pre-positioned to engage with the top profile. This preliminary engagement absorbs and compensates for the effects of floor irregularities, preventing them from propagating upward to cause disengagement of the idle wheels

AI summary
A sliding door device (14) comprising a frame element (19) securable to a vertical wall (15) and a guide and/or support component comprising at least one idle wheel configured to drive and/or support by way of a guide and/or support profile (21) a door (11) when sliding. The device (14) also comprises an anti-jamming component associated with the support component and configured to be moved and adjusted in vertical direction as to the frame element (19) at the same time as the support component so that the at least one idle wheel is brought into contact with the guide and/or support profile (21) and the anti-jamming component is brought into engagement with the profile (21). The invention also relates to a sliding door and a method of making the same sliding door.
