Drawer Slide Bracket Locator for Out-of-Square Cabinet Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tools fail to consistently and easily locate the mounting position of a rear bracket for drawer slide assemblies, leading to misalignment and premature failure due to out-of-square cabinet carcasses, which affects smooth drawer operation and functionality of features like soft close and push-to-open.
Innovation Solution
A mounting point locator tool comprising a base slidably mounted on a rod with a bracket holding fixture, where the base is secured to the cabinet face frame and the rod extended to position the bracket correctly on the rear panel, ensuring alignment with the face frame, even in non-square cabinets.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If drawer slide assemblies are mounted in non-square cabinets, then the mounting process becomes simpler, but the drawer slides become misaligned and bind during operation
Solution Approach 1:
The patent introduces a mounting template as an intermediary tool that mediates between the non-square cabinet structure and the square drawer slide assembly. The template compensates for the cabinet's lack of squareness by providing reference edges that are square to each other, allowing the drawer slide to be mounted correctly even when the cabinet itself is not square. This resolves the contradiction by enabling simple mounting procedures while ensuring reliable drawer slide operation.
2Adaptability or versatility
If the cabinet front face frame is not parallel with the rear panel, then cabinet manufacturing becomes more flexible, but drawer slide assemblies become out of alignment and fail prematurely
Solution Approach 1:
The patent applies preliminary action by providing a pre-fabricated mounting template that has already been manufactured with precise square reference edges. This template is prepared in advance and then applied to the cabinet during installation, eliminating the need for complex measurements and adjustments during the mounting process. The pre-established square references on the template ensure precise drawer slide alignment even when the cabinet lacks parallelism between face frame and rear panel.
3Adaptability or versatility
If the degree of misalignment is increased by cabinet frame depth, then undermount and side mount slides with rear brackets are more adaptable, but the misalignment problem is exacerbated
Solution Approach 1:
The patent addresses the depth-related misalignment problem by extending the mounting template into the third dimension (depth). The template includes reference features that extend from the front face frame toward the rear panel, providing square reference edges at multiple depths. This dimensional extension allows the template to compensate for misalignment that accumulates over the cabinet's depth, ensuring precise mounting location even for undermount and side mount slides with rear brackets.

AI summary
Disclosed is a mounting point locator tool for positioning a bracket of a drawer slide assembly such that the drawer slide assembly is square with the face frame of a cabinet carcass. The locator tool comprises a base perpendicularly extending from a first end of a rod. A bracket holding fixture is connected to a second end of the rod. In one embodiment, the base, the rod, and the fixture are ridgidly connected. In an alternate embodiment, the base is comprised of a sleeve extending generally perpendicular from a planar plate and slidingly engaged with the rod. The sleeve includes a pair of sides connected at a right angle for alignment with the face frame. The fixture includes a pair of prongs having edges spaced a predetermined distance and a set of slots having a predetermined width for releasably securing the bracket.
