Hose Tool With Hinged Handles And Plunger Bar Rack
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for inserting hose fittings into hoses require physical strength due to the difficulty in engaging fittings of the same diameter, making the process cumbersome and inefficient.
Innovation Solution
The Hose Tool features a head assembly with hose dogs and a handle assembly that includes hinged handles and a plunger bar rack, allowing for controlled expansion and collapse to guide and secure hose fittings into hoses, utilizing a spring mechanism for tension and easy operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If physical strength is used to insert hose fittings into hoses, then the fitting can be forced into the hose, but the process becomes cumbersome and requires excessive user effort
Solution Approach 1:
The patent introduces a hose tool as an intermediary device between the user and the hose fitting. The tool includes a plunger bar that pushes against the fitting and hose dogs that engage with the hose, mediating the insertion process and reducing direct user effort required to force the fitting into the hose.
Solution Approach 2:
The hose tool is divided into segmented components including multiple hose dogs that can independently engage with the hose, a plunger bar for applying force, and a handle assembly. This segmentation allows each component to perform its specific function efficiently, with the hose dogs gripping the hose while the plunger bar applies insertion force.
2Productivity
If a simple manual insertion method is used, then the device structure remains simple, but the insertion process becomes time-consuming and inefficient
Solution Approach 1:
The hose tool employs dynamic components including hinged handles that can pivot between open and closed positions, a movable plunger bar that extends and retracts, and spring-loaded latch pins. These dynamic elements allow the tool to adapt during the insertion process, enabling efficient operation while maintaining a relatively compact structure when not in use.
Solution Approach 2:
The insertion process utilizes periodic action through the cyclic opening and closing of the hinged handles. The handles are opened to position the hose dogs, closed to apply insertion force through the plunger bar, then opened again to release the fitting. This periodic cycle repeats until the fitting is fully inserted, improving efficiency through rhythmic, controlled motion.

AI summary
Embodiments of the Hose Tool are comprised of head assembly and handle assembly. The head assembly is comprised of a hose tab guide, a plurality of hose dogs, a plunger bar rack, and a hose tab guide sleeve. The handle assembly is comprised of a chassis, plunger bar rack, two handle pinons, a spring, two hinged handles, two bolts, a pivot pin, a guide bolt, two latch pins, and latch pin spring. The two hinged handles are attached to the two handle pinons via two bolts; held open by two latch pins being pressed into slot in two handles pinons by a latch pin spring. Depressing the two latch pins allows two hinged handles to swing alongside hose tool for storage. The two halves of two handle pinons are separated, timed and engaged within the plunger bar rack; then inserted into chassis and secured with pivot pin.
