  • Patent number: 11040457
    Abstract: A system and devices for guiding flexible corrugated hoses in industrial and robotic applications, where it is common to require tubing and electrical cables to be routed to various locations. A device for guiding such flexible hoses is described, comprising a rigid tube for containing a length of flexible corrugated hose and a spring element. A first end of the spring is fixed to an end of the tube, and a second end of the spring is fixed to an end of the flexible corrugated hose. The flexible corrugated hose may be drawn out of the tube against the force of the spring element, the spring element urging the flexible hose to return to a home position.

A first end of the spring is fixed to an end of the tube, and a second end of the spring is fixed to an end of the flexible corrugated hose. The flexible corrugated hose may be drawn out of the tube against the force of the spring element, in a longitudinal direction. A fitting for a robotic arm is also described, comprising an arc-shaped wall comprising a portion of a cylinder wall, with first and second plates fixed to top and bottom edges of the arc-shaped wall. The first and second plates of this device may be mounted within a joint of a robotic arm.
