Folding hinge for folding vehicle

Abstract

Hinge (10) for a folding vehicle, particularly for a folding bicycle (1), configured to allow pivoting, about a hinge axis (13), of a first portion of a vehicle tube (11) relative to a second portion of a vehicle tube (12) between a folded and an unfolded position of the vehicle, the hinge (10) comprising: an actuating arm (20) having, on the one hand, a first end portion (21) pivotally connected about a first axis (22) to the first portion of the tube (11) and, on the other hand, a second end portion (23); a connecting rod (24) of variable length having, on the one hand, a first end (25) pivotally connected about a second axis (26) to the second end portion (23) of the actuating arm (20) and, on the other hand, a second end (27) pivotally connected about a third axis (28) to the second portion of the tube (12),a locking device (30) configured to lock the hinge (10) in the unfolded position, an unlocking member (40) connected to the locking device (30) and comprising a gripping portion (41), the locking device and the unlocking member (40) being configured to allow a user pulling on the gripping portion (41) to act on the locking device (30) in order to unlock the hinge (10) to allow it to move into the folded position, the unlocking member (40) being at least partially made of a flexible material.

Claims

connecting rod (24) around the second axis (26), and an unlocked position, in which the first relief (31) does not cooperate with the second relief (32) which allows the connecting rod (24) to pivot around the second axis (26).

12. Hinge (10) according to the preceding claim, wherein the unlocking member is configured to move the first relief (31) from the locked position to the unlocked position.

13. Hinge (10) according to one of the two immediately preceding claims, wherein the locking device (30) comprises a return member (37), in particular a return spring, configured to control the automatic return of the first relief (31) from the unlocked position to the locked position, in the absence of actuation of the unlocking member (40).

14. Hinge (10) according to any one of claims 11 to 13, wherein the first relief (31) is formed at a first end (33) of a movable plate (34) configured to slide relative to the actuating arm (20) between the locked position and the unlocked position, a second end (35), opposite to the first end (33), of the plate (34) being fixed to the unlocking member (40).

15. Frame element (6, 7) for a folding vehicle, in particular for a folding bicycle (1), comprising a first portion of a tube (11) and a second portion of a tube (12) capable of pivoting relative to each other about a hinge axis (13) between a folded position and an unfolded position, and a hinge (10) according to any one of the preceding claims.
