Travel seat bag lifting device which can be disassembled and assembled integrally with bicycle

Abstract

A travel middle seat bag lifting device which can be disassembled and assembled integrally with a bicycle is composed of a lifting sleeve, a fixing sleeve, a left positioning bar and a right positioning bar, a left base plate and a right base plate, and positioning jaws, wherein the fixing sleeve is installed in a rear straight beam of the bicycle, the lifting sleeve is installed in the fixing sleeve, and the top end is connected with the bicycle seat bag; the locating jaw movable sleeve is connected the locating jaw pin hole by a pin shaft; If the cyclist needs to raise or lower the height ofthe seat bag, Pull on the cable attached to the handlebar, A return spring is compressed and disengages from the positioning groove by pulling the pin shaft positioning pawl, A lif spring raise or lowers that lifting sleeve, The hand releases the cable and the positioning claw enters the selected positioning groove. The beneficial effect of the technology is that the bicycle can be assembled on the bicycle rear straight beam integrally or disassembled integrally at any time without damaging the existing bicycle structural components. The height of the bicycle seat bag can be adjusted up or down without leaving the seat bag when the bicycle rider is traveling.

AI Technical Summary

Benefits of technology

This invention allows for easy assembly onto both front-straight legs of bike chairs while keeping them safe from being taken apart by others during transportation. It also reduces the size of the backrest portion when folded up, making it easier to carry around with other people's belongings.

Problems solved by technology

The patent text discusses the drawbacks of existing bicycles and a new invention called the "seat lifting system during bicycle driving." The text highlights two main technical problems with this invention. Firstly, the invention requires modifying the structure of the original bicycle by creating a groove in the rear straight beam. This modification is not desirable for both bicycle owners and manufacturers who are reluctant to change the existing bicycle structure. Secondly, the invention requires the rider to temporarily leave the seat and manually adjust the seat height using the lifting system while riding. This is inconvenient and there is currently no effective solution to address this issue.
