Sprinkler Installation Tool for Straight Thread Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for an installation device and method to properly locate fire protection sprinklers in their operative position within through holes of walls or ceilings without relying on tapered threads, especially for sprinklers with straight or parallel threads, and to ensure a captive escutcheon is flush-mounted, particularly in unfinished or finished wall systems.
Innovation Solution
The development of installation tools and methods that include a gauge and reference surfaces to locate the sprinkler frame and operational components within the through hole, using a rail member and guide member for sliding engagement, and an adjustable connection between the sprinkler and fluid supply pipe, allowing for flexible placement and centering of the sprinkler body and its components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If tapered threads are used for sprinkler installation, then the sprinkler can be securely coupled to the fluid supply piping, but the installation method is not compatible with sprinklers using straight or parallel threads
Solution Approach 1:
The patent introduces an intermediary installation tool that mediates between the sprinkler body and the wall structure. This tool includes a coupling mechanism that can accommodate both tapered and straight threads, allowing universal compatibility without requiring the sprinkler itself to change. The intermediary tool translates different thread types into a common mounting interface.
Solution Approach 2:
The installation system is segmented into separate functional components: the sprinkler body with its native thread type, the installation tool with adaptable coupling mechanisms, and the wall mounting structure. This segmentation allows each component to maintain its optimal design while achieving compatibility through the modular interface provided by the installation tool.
2Manufacturing precision
If the sprinkler is coupled to the fluid supply piping at sufficient depth within the through hole, then the captive escutcheon can be flush mounted to the wall mounting face, but the installation precision requirements increase
Solution Approach 1:
The installation tool incorporates preliminary positioning features such as depth gauges, alignment guides, and stop mechanisms that establish the correct sprinkler depth and orientation before final coupling. These preliminary actions ensure that when the sprinkler is installed at the sufficient depth required for flush mounting the escutcheon, the positioning accuracy is achieved without requiring excessive installation skill or repeated adjustments.
3Adaptability or versatility
If an adjustable fitting is used instead of tapered threads, then flexibility in sprinkler positioning is improved, but the ability to properly locate the sprinkler in its operative position becomes more difficult
Solution Approach 1:
The installation tool serves as an intermediary measurement and positioning device that works in conjunction with adjustable fittings. It includes measurement scales, alignment references, and positioning stops that enable the installer to accurately determine and achieve the operative position despite the flexibility provided by the adjustable fitting. The intermediary tool translates the flexibility into controllable, measurable adjustments.

AI summary
Installation tools and methods for installing a sprinkler within an opening or through hole in a wall or ceiling of an area to be protected. The tools include a reference surface and a gauge to be contacted by a sprinkler frame. The reference surface locates the gauge to define an operative position for the sprinkler frame and its operational components within a through hole of a wall.
