Claims

[Claims for Utility Model Registration] 1. A plurality of saddle installation height adjustment holes 29 formed in a scattered arrangement in a leg pipe 21 that integrally projects downward from a bicycle saddle 20; and the leg pipe 21. A seesaw arm mounting board 40 is attached to and integrated with the bicycle seat post 11 or its fixed extension tube 15 that can freely raise and lower the seat post 11 and its fixed extension tube 15, facing the outer peripheral surface of the leg tube 21. In the biased state, a compression spring 27 enclosed in the hollow interior of the seat post 11 or its fixed extension tube 15 is pivoted to the mounting plate 40 by a vertical shaft 45 so as to be able to swing around its fulcrum. From one end of the seesaw arm 46, the remote control lever 49 for raising and lowering the saddle attached to the steering handle 12 of the bicycle is removably engaged with the adjustment hole 29. Leg tube 2
1, a Bowden wire 48 connected and stretched between the other end of the seesaw arm 46 and the remote control lever 49, and the lock pin 47 inserted into the adjustment hole 29. The lock pin 47 resists the push spring 52 when the bowden wire 48 is pulled by the remote control lever 49. At the same time, the adjustment hole 29 of the leg tube 21
This bicycle saddle elevating device is characterized in that the leg tube 21 of the saddle 20 is set to automatically rise when separated from the bicycle saddle. 2. A plurality of saddle installation height adjustment holes 29 formed in a scattered arrangement in a leg tube 21 that integrally projects downward from a bicycle saddle 20, and a bicycle seat that receives the leg tube 21 in a manner that allows the leg tube 21 to be raised and lowered. A seesaw arm mounting board 40 is attached to and integrated with the post 11 or two fixed extension tubes 15 so as to face the outer peripheral surface of the leg tube 21, and the seat post 11 is in a biased state to constantly raise the leg tube 21. or a compression spring 27 enclosed in the hollow interior of the fixed extension tube 15; and a compression spring 27 that is also suspended from the rearward projecting piece 30 of the leg tube 21 in parallel with the leg tube 21; An elevating guide rod 31 that rises and lowers while maintaining a loose state with a stopper piece 33 correspondingly protruding from the mounting plate 40 is pivoted to the mounting plate 40 by a vertical shaft 45 so as to be able to swing around its fulcrum. The seesaw arm 46 and the remote control lever 49 for raising and lowering the saddle attached to the steering handle 12 of the bicycle are in a relationship in which they are removably engaged with the adjustment hole 29. tube 2
1, a Bowden wire 48 connected and stretched between the other end of the seesaw arm 46 and the remote control lever 49, and the lock pin 47 inserted into the adjustment hole 29. The lock pin 47 resists the push spring 52 when the bowden wire 48 is pulled by the remote control lever 49. At the same time, the adjustment hole 29 of the leg tube 21
A bicycle saddle characterized in that the leg pipe 21 of the saddle 20 is set to rise by itself after separating from the seat, and the limit of its rise and swing are regulated by the elevating guide rod 31. lift device.
