EXTENSION-RETRACTION DEVICE - A simplified explanation of the abstract

This abstract first appeared for US patent application 18501428 titled 'EXTENSION-RETRACTION DEVICE

The telescopic device described in the patent application consists of a telescopic tubular structure with an inner guide member. The outer belt and inner belt of the tubular structure have protrusions and holes arranged in two rows along the length of the structure. The inner guide member features first and second helical grooves that align with projections on the tubular structure.

  • The telescopic device includes a tubular structure with inner and outer belts, both having protrusions and holes in two rows.
  • An inner guide member with helical grooves aligns with projections on the tubular structure.
  • The device allows for smooth telescopic movement with precise alignment.

Potential Applications: - Industrial machinery for extending and retracting components - Automotive systems for adjustable parts - Aerospace technology for deployable structures

Problems Solved: - Ensures accurate and smooth telescopic movement - Provides stability and alignment during extension and retraction

Questions about Telescopic Device: 1. How does the inner guide member contribute to the telescopic movement? The inner guide member with helical grooves aligns with projections on the tubular structure, ensuring smooth and precise telescopic movement.

2. What are the potential applications of this telescopic device? This technology can be applied in industrial machinery, automotive systems, and aerospace technology for adjustable and extendable components.


Original Abstract Submitted

A telescopic device includes a telescopic tubular structure and an inner guide member. The outer belt and the inner belt of the tubular structure are provided with a plurality of protrusions and holes provided in two rows in the longitudinal direction. The inner guide member has a first helical groove and a second helical groove extending along a plurality of projections respectively provided in one row on the tip side and the base side of the tubular structure. The first straight line connects the end of the fitting portion where the first spiral groove and a part of the plurality of projections of the inner belt are fitted and the center axis of the cylindrical structure. A second straight line connects the terminal end of the second spiral groove and the central axis. The angle between the second straight line and the first straight line is less than 180 degrees.
