EXTENSION-RETRACTION DEVICE - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240209923 titled 'EXTENSION-RETRACTION DEVICE

Simplified Explanation: The extension-retraction device described in the patent application consists of two belts spirally wound around a tubular structure, with the second belt having an engaging pin that fits into a hole in the first belt.

  • The device includes a first belt and a second belt wound around the outside of the first belt.
  • The second belt features an engaging pin with a fitting portion that fits into a hole of the first belt.
  • The engaging pin also has an insertion portion that protrudes from the fitting portion and is inserted into the hole of the first belt.
  • The fitting portion of the engaging pin is cylindrical in shape, matching the diameter of the hole in the first belt.
  • The side surface of the insertion portion is inclined, decreasing in diameter towards the tip.

Potential Applications: 1. Industrial machinery for extension and retraction mechanisms. 2. Automotive systems for adjustable components. 3. Medical devices for adjustable parts in equipment.

Problems Solved: 1. Simplifies the design of extension-retraction mechanisms. 2. Provides a secure and efficient way to connect belts in a spirally wound configuration.
