Sliding Door Support Bracket With Side Locking and Flush Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing support brackets for sliding doors face challenges in minimizing the space between the sliding rail and the hanging element, requiring complex adjustments and often resulting in recoil and noise issues, especially when trying to achieve flush installation with ceilings.
Innovation Solution
A support bracket with a metal body and slider mechanism that allows for lateral height adjustment and locking without removing the hanging element, utilizing a torsion spring to prevent recoil and noise, and a design that reduces the space between the rail and the door or leaf.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If traditional frontal adjustment brackets are used, then height adjustment is possible, but the space between the sliding rail and hanging element remains large
Solution Approach 1:
The adjustment operation is moved from the frontal dimension (between rail and door) to the lateral dimension (along the rail). The bracket can be adjusted and locked from the side, allowing the door to be positioned flush with the ceiling while eliminating the need for frontal access space.
Solution Approach 2:
A lateral access mechanism is introduced as an intermediary approach. Instead of directly adjusting from the front, the system uses a lateral adjustment interface that allows operation from the side, thereby reducing the required frontal space while maintaining adjustability.
2Length of moving object
If lateral adjustment brackets are used, then access space is reduced, but tool attachment in the upper part adjacent to the rail creates problems
Solution Approach 1:
The bracket is divided into separate functional components: a body portion that attaches to the door, a lateral adjustment mechanism, and a locking system. This segmentation allows the adjustment function to be separated from the attachment function, simplifying the overall design and eliminating the need for complex upper-part tool attachments.
Solution Approach 2:
Instead of attaching tools to the upper part adjacent to the rail, the adjustment mechanism is inverted to allow lateral access from the side. The adjustment operation is performed from below or the side rather than from the upper frontal area, reversing the traditional approach.
3Ease of operation
If simple locking mechanisms are used, then ease of operation is improved, but recoil and noise occur at the end stroke
Solution Approach 1:
A damping element is incorporated into the locking mechanism to provide beforehand cushioning. This element absorbs the impact and prevents recoil at the end stroke, reducing noise and preventing dangerous oscillations while maintaining the simplicity of the locking operation.
Solution Approach 2:
The potential harmful recoil and impact at the end stroke are converted into a beneficial damping effect. The damping element transforms the harmful kinetic energy into heat through controlled deformation, eliminating noise and oscillations while maintaining the locking function.
4Measurement precision
If complex adjustment mechanisms are used, then adjustment precision is improved, but device complexity increases
Solution Approach 1:
The bracket incorporates a self-locking mechanism that automatically maintains the adjusted position without requiring complex fastening systems. The lateral adjustment design allows the door to be positioned and locked in place through simple lateral movement, with the structure itself providing the locking function rather than requiring additional complex components.

AI summary
A support bracket (10) with side locking and adjustment for sliding doors and leaves (22) is positioned and stabilized in a metal profile (14) attached with screws (26) in the cavity (18) formed along the upper edge of said doors or leaves and protrudes from the top of said profile with a threaded pin (54) designed to engage with a carriage (56) sliding in a rail (56′). The bracket comprises a body (12) of a substantially parallelepiped shape extending in a horizontal direction and with an open lower face, in the rear part of which opposite the mouth (14″) of the profile (14) a slider (28) is placed, fitted at the bottom with opposite projecting and inclined lugs (34) designed to abut with corresponding inclined portions (36) made in the lower part of the opposite sides of said body (12) for moving said slider. Said latter is provided with superposed through openings (30), (32), oriented in alignment with the longitudinal axis of the body (12), which respectively house a first screw (40) partially threaded and a second screw (46), said latter being moved with respect to the slider (28) starting from a through opening (44) made at the bottom of the rear face of said body (12).
