Hose Reel System

Patent Number: US 12252375 Grant Date: 2025-03-18 Filing Date: 2022-02-24

Overview

Filed on February 24, 2022 and granted on March 18, 2025, this patent protects a purpose-built reel system that streamlines setup and teardown for mobile foam-spraying operations. Drafted to address the practical challenges of long, mixed-function lines on trailers, the disclosed apparatus integrates a driven belt assembly with a center shaft that routes two separate fluids through sealed shaft-end couplers and bearing-coupling assemblies. Inventors based in Idalou, TX and an applicant based in Lubbock, TX engineered a system in which hoses, pneumatic and electrical lines can remain connected yet rotate freely, eliminating repetitive detachment and exposure of sensitive materials. The design includes pneumatic pump-driven actuation with a fail‑safe trigger for controlled winding, off-axis side-input ports for power, control and air, and a locking assembly to secure the spool during transport.

The firm’s prosecution emphasized robust mechanical and fluid-transfer details: internal fluid channels, rotating fluid input couplers, toothed belt interfaces, and serviceable bearings that preserve reservoir connections while the spool turns. These drafting choices protect reactive fluids from air exposure, reduce labor at job sites, and extend equipment life.

Key Features

  • Center shaft with dual shaft-end fluid inputs and rotating fluid outputs
  • Pneumatic pump drive, belt-and-teeth interface, and fail‑safe trigger
  • Side-input ports for electrical/pneumatic/controller lines and locking pin

By keeping transfer lines connected and automating winding, the invention reduces on-site labor and contamination risk. Its applicability extends across mobile spraying trades and industrial hose-management systems, offering measurable efficiency and safety advantages to contractors and OEMs.

Invention Details

Abstract: A reel system comprising a spool support, a belt drive assembly, a center shaft assembly, and one or more spool cross support bars. The reel system further comprises two spool side members having a first spool side member and a second spool side member. A spool portion comprises the two spool side members, the center shaft assembly and the one or more spool cross support bars. The spool portion is configured to mount between a first side support, a second side support. The spool portion is configured to rotate around a spool axis. The belt drive assembly comprises a drive system, and a belt. The drive system comprises a pneumatic pump driven drive system. The drive system comprises a drive shaft.

Summary of the Invention: A reel system for speeding up setup and teardown of a foam spraying system while increasing safety and protecting equipment. Said reel system comprises a spool support, and a spool portion. Said spool portion comprises a center shaft assembly, two spool side members having a first spool side member and a second spool side member. Said spool portion is configured to rotate around a spool axis, wherein said spool portion rotates about said spool axis. Said center shaft assembly comprises a first end and a second end, each rotatably supported by a bearing-coupling assembly. each end of said center shaft assembly comprises shaft-end fluid input. Said first end of said center shaft assembly comprises a first shaft-end fluid input and said second end of said center shaft assembly comprises a second shaft-end fluid input. Said first shaft-end fluid input is configured to receive a first fluid and said second shaft-end fluid input is configured to receive a second fluid. Said center shaft assembly comprises a shaft portion being between said two spool side members. Said center shaft assembly comprises two or more fluid outputs in said shaft portion. Said two or more fluid outputs comprise a first fluid output, and a second fluid output. Said reel system is configured to receive said first fluid and said second fluid at opposite ends of said center shaft assembly in said first shaft-end fluid input and said second shaft-end fluid input and deliver them to said first fluid output and said second fluid output, respectively. Said two or more fluid outputs are located in said shaft portion to allow a first end of two hoses to connect to and rotate with said center shaft assembly. each among said bearing-coupling assembly comprises a bearing, and a fluid input coupler. Said center shaft assembly is configured to slide through and rotate within said bearing.
