Hose Reel Rewind Speed Control

Abstract

The invention is a centrifugal brake device that is a speed control means for spring motor hose and cable reels. This brake device is mounted to a shaft of a hub associated with the reel, such that the device controls the reel rotation speed.

AI Technical Summary

Benefits of technology

The patent text describes an improved design for a spring motor reel that solves problems with traditional reel designs related to controlling the rewind spring. The improvement is a better braking system for the reel. The technical effect of this design is improved control of the rezip rewind spring, which results in better performance and reliability of the reel.

Problems solved by technology

There is an associated problem, however, in that the controlled rewind speed of the hose or cable is dependent on the operator maintaining control of the hose end and allowing for slow rewind of the hose by applying a resistance to the rewind process by keeping hold of the hose itself.

If the hose is accidentally released by the operator while still being mostly unwound, then it will rewind of its own accord in a most violent and rapid manner.

It is in these circumstances that serious personal injury can occur to personnel near the reel or that damage can occur to the reel apparatus or other items in the vicinity of the reel and hose.

These methods are expensive and complex and require maintenance and fine tuning, thus working against the original low-cost concept of the spring motor reel itself.
