EXTENSION-RETRACTION DEVICE - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240288054 titled 'EXTENSION-RETRACTION DEVICE
The patent application describes an extension-retraction device with an outer strip member, an inner strip member, a tubular inner guide member, and a cylindrical member.
- The outer strip member and inner strip member have engaging portions.
- The tubular inner guide member includes a groove portion.
- The cylindrical member guides the strip members between its inner and outer peripheries.
- A friction-reducing portion on the cylindrical member reduces friction with the strip members.
Potential Applications: - This technology could be used in retractable mechanisms for various devices. - It may find applications in adjustable length systems for different products.
Problems Solved: - Reduces friction between moving parts in extension-retraction devices. - Provides smooth and efficient operation of the mechanism.
Benefits: - Improved durability and longevity of extension-retraction devices. - Enhanced user experience with smoother operation. - Increased efficiency in adjusting the length of devices.
Commercial Applications: Title: "Efficient Extension-Retraction Mechanism for Various Devices" This technology can be utilized in retractable antennas, adjustable stands, and retractable cords for consumer electronics.
Questions about Extension-Retraction Devices: 1. How does the friction-reducing portion on the cylindrical member enhance the performance of the device?
The friction-reducing portion reduces wear and tear on the moving parts, resulting in smoother operation and increased longevity.
2. What are the potential challenges in implementing this technology in different products?
The main challenge could be adapting the design to fit specific devices while maintaining optimal functionality.
Original Abstract Submitted
an extension-retraction device in which: each of an outer strip member and an inner strip member includes one or more engaging portions; a tubular inner guide member and a cylindrical member are included, the inner guide member including a groove portion, and the cylindrical member being made up in a cylindrical shape so as to conform to an outer peripheral surface of the inner guide member and helically guiding each of the inner strip member and the outer strip member between an inner periphery of the cylindrical shape and an outer periphery of the inner guide member; and the cylindrical member is provided with a friction reducing portion that reduces friction at each of a location in which the inner periphery of the cylindrical member contacts the outer strip member and a location in which the inner periphery of the cylindrical member contacts the inner strip member.
