Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a bicycle saddle lifting device capable of easily adjusting the height of a saddle while riding a bicycle.

[0002]

[Prior art]

 In a general two-wheeled bicycle, which is a vehicle driven and driven by human power, the rotation of the crank due to the pedaling force applied to the pedals is converted into the rotational drive of the rear wheels through the chain, so it is most efficient according to the leg force of the occupant. It is necessary to adjust each part so that it can drive easily and easily.

[0003] In particular, in order for the occupant to step on the pedal and to obtain a large rotational force on the crank with leg force efficiently and easily, it is desirable to raise the saddle so as to fully utilize the leg force. It is common to ride with the height adjusted to an appropriate height.

[0004]

[Problems to be solved by the device]

 However, if the saddle is set too high in advance, it will be very inconvenient to get on and off. Especially when riding a bicycle, that is, when riding the saddle of a bicycle for the first time, or when riding over a high saddle and stopping, both legs do not touch the ground, which is very dangerous and an unexpected traffic accident. It was an incentive to invite such things. On the other hand, lowering the saddle so that both feet touch the ground requires a large amount of leg strength, which makes driving difficult.

[0005]

[Means for Solving the Problems]

 The present invention has been made to solve the above problems, and has the following configuration. That is, the gist of the present invention is to provide a middle cylinder having a vertically engaging peripheral groove that is vertically inserted into a seat post of a frame, and at least a spring for constantly biasing the middle cylinder upward. A cushioning device and a member provided with a seat post and provided with a spring-biased locking claw for selectively engaging with one of the upper and lower engaging circumferential grooves to lock the middle cylinder at a predetermined position. It consists of a stopper, a height-adjustable saddle attached to the upper end of the middle cylinder, and an operating lever for operating the locking claws of the locking device. This is a bicycle saddle lifting device characterized by adjustable height. Next, the present invention will be described in detail with reference to the drawings with reference to the following embodiments.

[0006]

【Example】

 First, reference numeral 3 is a middle cylinder having upper and lower engaging circumferential grooves 8 and 9 which are vertically inserted into the seat post 2 of the bicycle frame 1. The middle cylinder 3 is provided with a sliding key 10 and is fitted in a key groove provided in the lid 2a of the seat post 2 to prevent rotation. A piston 6 in a cylinder 5 fixed to the seat post 2 is connected to the lower end of the lower end rod 3a of the middle cylinder 3, and the middle cylinder 3 is always moved upward between the piston 6 and the lower bottom of the cylinder 5. A spring 7 for biasing is interposed to form a shock absorbing device 4 of a spring piston (a shock absorbing effect is caused by compression of air and spring). Further, 11 is an urging force of a spring 14 which is provided on the seat post 2 and selectively engages with either of the upper and lower engaging circumferential grooves 8 and 9 to lock the middle cylinder 3 at a predetermined position. The locking device includes a locking claw 13 that is opened. Reference numeral 12 is a cylindrical box of the locking device 11. Reference numeral 17 denotes a height adjustable saddle in which a saddle shaft 16 is vertically inserted into the upper portion of the middle cylinder 3, and the saddle 17 can be mounted and fixed at an arbitrary height by a saddle fixing lever 18. Further, reference numeral 20 is an operation lever provided on the handlebar 19 of the bicycle, which is connected to the locking claw 13 of the locking device 11 by the operation wire 15 so that the locking claw 13 can be operated. The height of the saddle 17 can be adjusted by operating the lever 20 while straddling the saddle 17.

[0007]

[Explanation of action]

 1 and 2, the saddle 17 is locked and locked in the lowered position. That is, in FIG. 2, the locking claw 13 of the locking device 11 is engaged with the upper engaging peripheral groove 8 of the middle cylinder 3 by the action of the spring 14. Then, the saddle 17 is ridden on the bicycle to start running, and then the operating lever 20 is appropriately operated to disengage the locking claw 13 from the upper engaging circumferential groove 8 and lift the waist slightly above the saddle 17. Then, the action of the spring 7 raises the middle cylinder 3. Immediately after the operation lever 20 is operated, by releasing the hand from the operation lever 20 and releasing the lever, the locking claw 13 is engaged with the raised lower engaging circumferential groove 9 by the action of the spring 14 and the saddle 17 is moved to the raised position. It will be locked and locked. Next, when the saddle 17 is running in a high state and stopped, if the operating lever 20 is operated in the same manner as above, the weight of the occupant who straddles the saddle 17 causes the middle cylinder 3 to descend against the spring 7. The locking claw 13 is again engaged with the upper engaging circumferential groove 9 by the action of the spring 14 to lock the saddle 17 in the lowered position, so that the saddle 17 is stopped in a low state and the bicycle can be safely and easily dismounted. be able to.

[0008]

[Effect of device]

 As described above, the bicycle saddle lifting device of the present invention is very useful because the height of the saddle can be easily adjusted while riding on the bicycle straddling the saddle. When riding and getting off the bicycle, the saddle can be lowered, and when riding the bicycle, the saddle can be raised to enjoy the safe, efficient, easy and light cycling. In addition, the height of the saddle can be easily changed to adapt to conditions such as leg strength, road ups and downs, unevenness, and wind direction to facilitate running.
