Pry Bar Holder with Blocking Beam
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tool holders, particularly those designed for carrying pry bars, are either unsafe due to the pry bar's shape causing it to tilt and fall, or overly complex and expensive, lacking a simple and cost-effective solution for secure attachment to a belt without additional attachment devices.
Innovation Solution
A pry bar holder with a plate member featuring an elongated holding slot and a blocking beam to prevent tilting, attached directly to a belt or a backrest, allowing the pry bar to hang vertically and securely, accommodating various tools without additional attachment structures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a generic tool holder with a simple horizontal holding loop is used, then the device is simple and inexpensive, but the pry bar tilts and falls off due to its shape
Solution Approach 1:
The holding loop is segmented into multiple functional zones: an upper curved portion for receiving the pry bar, a lower curved portion for support, and lateral sides for confinement. This segmentation allows each portion to perform a specific function in preventing tilting and falling, resolving the contradiction between simplicity and reliability.
Solution Approach 2:
The holder design incorporates preliminary anti-action by creating a pre-formed vertical holding configuration that counteracts the natural tendency of the pry bar to tilt horizontally. The curved portions and lateral sides are positioned in advance to prevent tilting before it occurs, eliminating the need for complex adjustment mechanisms.
2Reliability
If a complex prior art pry bar holder with separate slots and rests is used, then the pry bar is securely held, but the device becomes significantly more expensive
Solution Approach 1:
Multiple separate components (holding slot, claw rest, handle rest) are merged into a single integrated holding loop structure. The loop simultaneously provides vertical holding, lateral confinement, and support functions that were previously distributed across multiple separate parts, reducing complexity while maintaining reliability.
Solution Approach 2:
The holding loop is designed as a multi-functional universal structure that can accommodate different pry bar configurations (single claw, double claw, various handle shapes) through its curved geometry, eliminating the need for specialized slots and rests for each tool type.
3Device complexity
If a generic tool holder with the backrest directly attached to the belt is used, then the holder is simple, but the pry bar must be held very close to the body causing safety concerns
Solution Approach 1:
The holder design transitions from a horizontal holding orientation to a vertical holding orientation through the curved geometry of the loop. This dimensional change allows the pry bar to hang vertically with claws pointing upward, moving the tool away from the body and eliminating the hazard of claws pressing against the user.

AI summary
The current invention discloses a safe and inexpensive tool holder designed to accommodates a pry bar or other tools. The holder comprises: a plate member having a top surface and a bottom surface, wherein the plate member has an elongated holding slot connecting the top surface to the bottom surface and sized to be a loose fit to the pry bar, the elongated holding slot roughly divides the plate member to a proximal section and a distal section; a blocking beam attached to the bottom surface of the plate member, residing adjacent to the elongated holding slot and on the distal section of the plate member; and attachment structures that affix the plate member to the belt. The pry bar holder may further comprise a specially designed backrest that attaches the pry bar holder to a belt.
