hinges for folding bikes

Abstract

A hinge (10) for folding a bicycle, comprising a first tubular portion (20), a second tubular portion (30), the first tubular portion and the second tubular portion can adopt an unfolded posture and a folded posture a blocking element (40), which can adopt at least one closed position and one opened position, in which it keeps the first tubular portion and the second tubular portion in the expanded position, and in which it allows movement to the first and second tubular portions in the opened position; The folded position of the second tubular part; a connecting member (50) and a return means (60) configured to bring the blocking element from its open position back to its closed position.

Description

technical field [0001] The present invention relates to the field of folding bicycles and, more precisely, to the device for folding and maintaining in an unfolded position for such folding bicycles. Background technique [0002] Folding bicycles traditionally include at least one hinge that allows a tubular assembly consisting of a first tubular portion and a second tubular portion to be placed in a folded or unfolded position. It is known to arrange such hinges on the handlebar stem, on the frame, or even on the seat stem of a folding bicycle. [0003] A folding bicycle hinge must allow the user to place the bicycle in a folded position very quickly, to be able to store it or to reduce its bulk in order to be able to carry it easily, especially when the user desires to commute by public transportation. [0004] Furthermore, in order to avoid the bicycle collapsing and injuring the user during use by the user, it is essential to be able to hold the bicycle, more precisely,...

AI Technical Summary

Problems solved by technology

[0007] A disadvantage of this device is that the force applied to press the lever against the tubular assembly may be so great that the user may experience difficulties effectively securing the connection between the two tubular parts

[0008] Also, such hinges are usually placed close to the wheel, and the lever may be covered in mud

So actuating the lever may get the user's hands dirty

[0009] Furthermore, if the user forgets to press the lever against the tubular assembly or does not press it properly, the hinge runs the risk of collapsing during bicycle use, which could be very dangerous and could result in a serious fall
