Bicycle Saddle Lifting Device

Abstract

The present invention relates to a saddle lifting device for a bicycle and, more specifically, relates to a saddle lifting device for a bicycle which is designed to take into consideration the mechanical relationship between the amount of the driving force exerted by a pedal crank and the fatigue of the leg muscles in accordance with the stable landing of the feet when the vehicle is parked and the leg bending and leg stretching when driving. In the case of parking, the bicycle starts running with a low saddle. When a driver suddenly enters into the running mode, depresses the pedal and stands up, the saddle position is changed through instantaneous operation so as to use the weight as a power source to reduce leg muscle fatigue and protect the prostate. The driver can ride the bicycle stably and rapidly for a long time, and can lower the saddle when parking in the running state or encountering a sudden situation in the running state. Parking can be realized through lowering the saddle and safe landing of the two feet.

Description

Technical field [0001] The present invention relates to a saddle lifting device for a bicycle, and more specifically, to a saddle lifting device for a bicycle. The saddle lifting device for a bicycle takes into consideration the stable landing of the two feet when parking and the bending and extension of legs when driving. It is designed based on the mechanical relationship between the driving force exerted by the crank pedal and the fatigue of the leg muscles. It starts with a low saddle when parking. When suddenly entering the driving mode, step on the pedal and stand up. Through instant operation To change the position of the saddle, use body weight as the power source to reduce the fatigue of the leg muscles and protect the prostate. It can ride a bicycle smoothly and quickly for a long time, and can park and encounter unexpected situations during driving. At the same time, the saddle can be lowered to quickly and safely land on both feet to realize parking. Background tech...

Problems solved by technology

[0002] The technology for adjusting the height of the saddle of a bicycle is disclosed in the prior art. The published registered patent No. 10-0864173 is a structure for adjusting the height in stages. In the structure, the lock on the locking device box is elastically supported by a coil spring. It meshes with the support plate gear, and adjusts the height of the saddle by adjusting the rotation degree of the main rod, so that during use, due to the inability to accurately achieve the engagement between the lock and the support plate gear, misoperation will occur, and due to the saddle’s The self-weight and the force of the spring supporting the saddle are transmitted to the main rod, therefore, a supporting force is transmitted to the lock for pulling out from the support plate gear, resulting in the lock being difficult to pull out from the support plate gear, resulting in a problem of not being able to operate smoothly Defects
