Sliding Door Bracket With Lateral Adjustment Mechanism
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 or precise leveling.
Innovation Solution
A support bracket with a metal profile that allows for easy height adjustment and lateral locking without removing the hanging element, utilizing a slider mechanism with inclined lugs and a torsion spring to stabilize and adjust the door or leaf, reducing the space between the rail and the hanging element while preventing recoil and noise.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If traditional support brackets are used with frontal adjustment, then height adjustment is possible, but the space between the sliding rail and hanging element remains large
Solution Approach 1:
The patent inverts the traditional adjustment approach by moving from frontal adjustment (from the front of the bracket) to lateral adjustment (from the side of the bracket). The adjustment mechanism is accessed through the lateral face of the bracket body, allowing the hanging element to be positioned closer to the sliding rail while maintaining ease of adjustment through side-accessible adjustment means.
Solution Approach 2:
The patent transitions the adjustment access from one dimension (frontal access requiring significant front space) to another dimension (lateral access through the side face). This dimensional change allows the hanging element to be positioned closer to the sliding rail in the frontal direction while the adjustment mechanism is accessed through the lateral dimension.
2Length of moving object
If lateral adjustment brackets are used, then space between rail and element is reduced, but adjustment requires removing the hanging element from the bracket
Solution Approach 1:
The patent inverts the adjustment access approach by providing adjustment means accessible through the lateral face of the bracket body, allowing adjustment without removing the hanging element. This resolves the contradiction by maintaining lateral access (reducing space) while eliminating the need to detach the hanging element.
3Manufacturing precision
If precise lateral adjustment is required, then adjustment accuracy improves, but the bracket structure becomes more complex
Solution Approach 1:
The bracket body serves multiple functions: it supports the hanging element, provides lateral adjustment access through its face, and integrates the adjustment mechanism. This multi-functionality achieves precise adjustment without proportionally increasing structural complexity, as the same bracket structure accomplishes both support and precise positioning functions.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution enables precise and easy adjustment of sliding doors to be flush with ceilings, reduces the space between the rail and the hanging element, and minimizes recoil and noise, ensuring reliability and resistance over time.
Implementation Method 1
a torsion spring (74) made of harmonic steel... which, being connected to the carriage (56), prevents the door or leaf (22) from being subjected to impact and violent recoils in the vertical direction
Implementation Method 2
a torsion spring (74) made of harmonic steel, typically in the form of a foil
Implementation Method 3
a threaded pin (54) inserted in an opening (52) extended vertically... By acting on the screw (54) the bracket (10) is moved in height
Implementation Method 4
a slider (28)... consisting of a prismatic body provided with superposed and aligned openings... The bracket (10)... is stabilised in it by means of a slider (28)... which makes the bracket (10) rise

AI summary
A support bracket (10) with side locking and adjustment for sliding doors and leaves (22) is positioned and stabilised 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).
