Air-Conditioning Support Bracket With Retained Sliding Screws
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing support brackets for air-conditioning plant units are cumbersome and complicated to install, particularly at heights, due to the risk of locking screws falling out during anchoring.
Innovation Solution
A support bracket with elongate slots in the second portion that slidingly engage with screw members, preventing them from falling out until locked by a nut, allowing easy installation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If locking screws are used to anchor equipment to the bracket, then the equipment can be securely fixed, but the screws may fall out during installation requiring the fitter to retain them
Solution Approach 1:
The patent introduces an intermediary retention mechanism (the bracket structure itself) that prevents the screw from falling out. The screw passes through a slot in the bracket, and the bracket's geometry acts as a physical barrier that retains the screw head or shaft, eliminating the need for the fitter to manually hold the screw during installation.
Solution Approach 2:
The bracket is pre-configured with slots and retention features before installation. The screw is designed with a head or shaft geometry that will be retained by the bracket structure, so the retention function is built into the system beforehand rather than requiring manual intervention during the anchoring process.
2Reliability
If the fitter must retain the locking screw until the nut is screwed on, then secure anchoring is achieved, but the installation process becomes complicated especially at heights
Solution Approach 1:
The bracket structure serves as an intermediary retention mechanism that automatically holds the screw in place through its slot geometry. This eliminates the need for complex manual retention procedures and simplifies the installation process, especially when working at heights where manual retention would be difficult.
Solution Approach 2:
The bracket structure provides self-retention of the screw through its built-in slot geometry. The system serves itself by automatically retaining the screw without requiring external manual intervention, thereby simplifying the installation procedure while maintaining secure anchoring.
3Ease of manufacture
If traditional L-shaped brackets with through-holes are used, then equipment can be fixed to walls, but the screws may fall out and complicate the fixing operations
Solution Approach 1:
The bracket is designed with localized retention features at specific locations where screws pass through. The slot geometry is modified locally to include retention edges or barriers that prevent screw drop-out, while the rest of the bracket maintains its simple L-shaped construction for ease of manufacture.
Solution Approach 2:
The bracket structure acts as an intermediary that provides both the simple L-shaped construction for ease of manufacture and the retention function for screw security. The slot geometry in the bracket mediates between these two requirements by incorporating retention features into the otherwise simple structure.

AI summary
There is described a support bracket for equipment, in particular units for air-conditioning plants, comprising a first bracket portion and a second bracket portion (2, 3) which are arranged for anchoring the bracket to a wall and for supporting and fixing the equipment to the bracket, respectively, the first and second bracket portions (2, 3) being able to be secured to each other in an operating condition, in which they assume an L-shaped configuration suitable for supporting the equipment, there being defined on the second bracket portion (3) a surface portion (4) which is intended for the supporting contact of the equipment, the surface portion (4) being provided with at least one through-opening (5) which is in the form of an elongate slot, for engaging in a sliding manner with at least one respective screw type member (6) which is intended to anchor the equipment on the corresponding bracket, the screw type member (6) comprising a head (8) and a threaded shank (9) which extends from the head, and comprising, in the region of the head, a pair of opposite seats (10a, 10b), each seat being configured to be connected, with sliding engagement, to a corresponding peripheral edge of the through-opening (5) so that the screw type member (6) is retained in a manner slidingly guided along the opening (5), thereby preventing the screw type member (6) from falling out of the opening.
