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

VSEngineering 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

Engineering Contradiction:
Improvespace between sliding rail and hanging elementVSAvoidadjustment operation
Core Design Contradiction:
Length of moving objectVSEase of operation

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.

Inventive Principle:
Principle #13The other way round (Inversion)

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.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

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

Engineering Contradiction:
Improvespace between sliding rail and hanging elementVSAvoidadjustment operation
Core Design Contradiction:
Length of moving objectVSEase of operation

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.

Inventive Principle:
Principle #13The other way round (Inversion)

3Manufacturing precision

If precise lateral adjustment is required, then adjustment accuracy improves, but the bracket structure becomes more complex

Engineering Contradiction:
Improveadjustment precisionVSAvoidbracket structure
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

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.

Inventive Principle:
Principle #6Universality (Multi-functionality)

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).
