Description

Bicycle saddle height adjustment device

The present invention relates to a height adjusting device for a chair, and more particularly, to a bicycle saddle height adjusting device for adjusting the height of a bicycle saddle.

In general, a bicycle saddle needs to arbitrarily and appropriately adjust the height of the saddle according to the physical condition of the bicycle user.

In particular, a bicycle saddle needs to be able to fully extend its legs when the pedal goes down while riding, so it has the least power and allows you to ride comfortably with a correct body posture. There is a simple method of fixing the seat post with a seat post clamp after changing the relative position of the seat post inserted into the tubular seat tube so that the height of the bicycle saddle can be adjusted accordingly. .

In this case, when the bicycle is stopped and stopped, the position of the foot on which the pedal is pressed is separated from the ground by a predetermined distance, so the stopping posture while riding the bicycle is very unstable and overturned, or while sitting on the bicycle saddle while waiting for a stop, use the high chin of the ground As a result, cumbersome and inconvenient behavior was caused when one foot was supported on the ground or waiting for a stop after getting off the bicycle saddle.

Therefore, a bicycle saddle height adjuster to which various technologies such as a pneumatic and hydraulic height adjuster and a mechanical height adjuster are applied so that the user can more conveniently adjust the height while riding a bicycle has been developed.

However, even now, although a bicycle saddle height adjustment device has been developed and used, most of them are composed of a hydraulic and pneumatic mixed use method in which one working cylinder is mixed and filled with oil and gas. In the mixed use method, it is difficult for general users to refill the oil or gas filled at the time of initial production and use it, and the control valve that controls the working fluid is composed of an up-down withdrawal method. Due to a phenomenon in which the valve is opened and closed arbitrarily, there was a phenomenon of gap between the up and down operation of the seat post in which the bicycle saddle was raised to a certain height from the operating cylinder.

Above all, since most of the levers of the control valve of the bicycle saddle height adjuster are placed on the upper side of the seat post, and the remote cable line for remote control is connected to the lever of the control valve, the arrangement of the remote cable on the outer circumferential surface of the seat post is variably fluid, so the bicycle seat post The surroundings are intricately constructed.

Also, since the height of the bicycle saddle height adjuster is limited to the maximum height of the operating cylinder, use the seat post clamp placed on the bicycle seat tube to raise the bicycle saddle height adjuster further from the seat tube according to the physical condition of the cyclist. In the lowering height adjustment work, the height adjustment work of the bicycle saddle is inaccurate, so the saddle height adjustment work is somewhat cumbersome. It was very inconvenient and cumbersome to adjust the height.

On the other hand, in the bicycle saddle height adjustment device, a fixed groove formed at a predetermined interval perpendicular to the outer circumferential surface of the seat post, and an adjustment member inserted into the fixed groove to adjust the lowering operation height of the seat post, The mechanical height adjustment device composed of a coil spring for inducing the ascending operation of the seat post has the advantage of being simple in configuration, but when adjusting the height of the bicycle saddle, stepwise adjustment of the height according to the arrangement of the fixing groove is produced to adjust the height of the saddle. It is not more delicate than this, and above all, when the size of the fixing groove is worn and deformed with the adjusting member that is in contact for a long time, an abnormal phenomenon that the up and down flow gap of the bicycle saddle height adjustment device is produced frequently occurs. have.

While the valve seat 125 is blocked, when the pull-out connection line 10 is withdrawn, the driving unit 134 of the control valve means 130 is driven in reverse rotation so that the valve seat 125 remains open, and the inner box The oil fluid stored in the power pressure chamber P1 of the cylinder 300 flows out into the oil chamber C1 through the oil passage 133 formed in the valve body 132 of the control valve means 130 to the inner cylinder 300 The lowering operation of the rod member 400 including the piston 410 disposed in the .

On the other hand, when the piston 410 of the inner cylinder 300 is operated upward in the state in which the control valve means 130 is opened as described above, the volume of the power pressure chamber P1 of the inner cylinder 300 increases. Since a suction force is formed, the oil fluid stored in the oil chamber C1 is sucked through the oil passage 133 formed in the valve body 132 of the control valve means 130 .

At this time, since the compressed fluid stored in the air pressure chamber P2 of the enclosure cylinder 100 acts on the oil chamber C1 through the through passage 126 in the oil chamber C1, the oil fluid stored in the oil chamber C1 is The compressed fluid is smoothly introduced into the inner cylinder 300 by the expansion pressure of the air pressure chamber (P2).

In addition, preferably, in the state in which the control valve means 130 is blocked, the upward operation of the piston 410 is limited according to the oil-fluid incompressibility characteristic of the power pressure chamber P1 formed in the inner cylinder 300, so the control valve means 130. By using the opening and closing of the seat post of the present invention, it is possible to freely control and adjust the height of the ascending operation and the descending operation.

Hereinafter, another preferred embodiment of the oil-fluid control valve means acting on the inner-cylinder power pressure chamber P1 of the present invention will be described.

As illustrated in FIG. 18 of the accompanying drawings, an oil covering 140a forming an oil chamber C1 is formed on the lower portion of the cylinder head 120, and a valve seat 125 is formed on the cylinder head 120 as well. , in which the control valve means 130a is configured in a screw-coupled manner as described above,

Preferably, the control valve means 130a is composed of a valve body 132a including a valve body 131a, a driving part 134a, and a driving winding part 135a, and an oil fluid is provided in the valve body 132a. One end of the torsion spring 150 provided to the driving unit 134a of the control valve means 130a is formed with the oil passage 133a for entering and exiting, and a fixing member 136a is formed on one side of the lower surface of the valve body 132a. It is fixed, and at this time, the other end of the torsion spring 150 is fixedly disposed in the coupling hole 122b of the cylindrical body 122 configured on the lower surface of the cylinder head 120 .

In addition, the driving winding part 135a configured under the driving part 134a of the control valve means 130a penetrates the sealing member 147a and the doorway 146a provided on the covering member 140a and protrudes downward. , the pull-out connection line 10b is rotated by the coupling member 137a to prevent leakage of the oil fluid stored in the oil chamber C1, and to open and close the control valve means according to the withdrawal of the draw-out connection line 10b. do.

Preferably, the draw-out connecting line 10b is connected to the drawing-out means of the covering member along the outer circumferential surface of the enclosure cylinder 100 through a guide hole 144a formed on one lower side of the oil covering 140a.

Thus, when the draw-out connection line 10b is withdrawn, the control valve means 130a is opened and the oil fluid stored in the power pressure chamber P1 of the inner cylinder 300 is transferred to the valve seat 125 and the valve body 132a. The piston 410 disposed in the inner cylinder 300 is discharged to the oil chamber C1 through the oil passage 133a and the piston 410 is lowered. At this time, when the oil discharged to the oil chamber C1 is full, the cylinder head It flows out into the air pressure chamber P2 formed in the enclosure cylinder 100 through the through hole 126 formed in the 120 .

On the other hand, when the tension of the pull-out connection line 10b is released, the control valve means 130a is driven by the elastic force of the torsion spring 150 provided to the driving part 134a of the control valve means 130a, and the control valve means 130a is driven. ) of the valve body 131a blocks the valve seat 125, so the power pressure chamber P1 of the inner cylinder 300 is cut off with the oil chamber C1 and the piston ( 410) the lifting operation is stopped.

Preferably, in the power pressure chamber P1 of the inner cylinder 300, the suction pressure is greatly increased due to the characteristics of the incompressible oil fluid, so that the upward operation of the rod member 400 including the piston 410 is limited, so the seat post 200 ) is maintained in a stopped state, and the up-and-down play of the bicycle saddle is prevented.

A preferred embodiment and another embodiment according to the present invention have been described. Hereinafter, a preferred embodiment in which the raising and lowering of the seat post is performed with respect to the bicycle saddle height adjusting device of the present invention will be described.

As described above, the oil fluid is stored in the power pressure chamber P1 of the inner cylinder 300 and the oil chamber C1 formed in the oil covering 140 as illustrated in FIG. 19 of the accompanying drawings as well as the seat post 200 ) and the compressed fluid is stored in the air pressure chamber P2 configured in the enclosure cylinder 100 through the air injection member 240 .

Therefore, when the seat post 200 is operated upward by the action of the compressed fluid of the air pressure chamber P2, the bicycle saddle coupling means 800 is in a “road-off” state (for example, external force generated from the saddle) in which no external force is applied. is not applied), and at this time, the height adjustment member 230 and the inner cylinder 300 of the seat post 200 are limited to a predetermined length and are mutually bound by the adjusted connecting line 20, so that the seat post 200 is The oil fluid stored in the oil chamber C1 according to the open state of the control valve means 130 is lifted to a predetermined height according to the length of the connecting line 20 and the power pressure chamber P1 of the inner cylinder 300 is operated. will inhale

Preferably, the lifting operation of the seat post 200 is; In the “Load Off” state in which no external force is applied to the saddle coupling means 800 and in the open state of the control valve means 130 , a lifting operation is performed, in which case the control valve means 130 is connected to the withdrawal means 500 . The open state of the control valve means 130 is produced according to the withdrawal of the lead-out connection line 10 .

In this way, when the lifting operation of the shift post 200 is completed and the pull-out means 500 is operated to release the pull-out connection line 10 from the drawn-out state (loop state without tension of the pull-out connecting line), the control valve means 130 is torsion Since it is blocked by the resilient force of the spring 150, the power pressure chamber P1 of the inner cylinder 300 is cut off with the oil chamber C1, and the height of the seat post 200 is maintained at a set height.

And as described above, in a state in which the seat post 200 has been raised, the “Load On” state in which an external force acts on the saddle coupling means 800 (eg, a state in which a person sits on the saddle and an external force is applied to the saddle) When the power pressure chamber (P1) of the inner cylinder 300, the hydraulic force proportional to the external force is applied according to the blocking state of the control valve means 130 described above, so the rod member 400 disposed in the inner cylinder 300. will stop the lowering operation.

Therefore, the lowering operation of the post head 220 and the seat post 200 fixedly coupled to the rod member 400 is stopped, and the set height of the bicycle saddle is maintained.

When it is necessary to adjust the height of the bicycle saddle to a low level while riding a bicycle, as exemplified in "FIG. 19-1" in the attached drawing 19, an external force acts on the bicycle saddle coupling means 800 in a "Load On" state (eg, a person When the control valve means 130 is opened by using the withdrawal means 500 in the state where an external force is applied to the saddle while sitting on the saddle, the oil fluid stored in the power pressure chamber P1 of the inner cylinder 300 is It is discharged to the oil chamber (C1).

Therefore, the lowering operation of the seat post 200 fixedly coupled to the rod member 400 in which the hydraulic action of the piston 410 of the power pressure chamber P1 is produced is produced to lower the set height of the bicycle saddle, at this time the oil A part of the oil fluid discharged to the chamber C1 flows out into the air pressure chamber P2 of the enclosure cylinder 100 .

In addition, at this time, according to the lowering operation of the seat post 200, the air pressure chamber P2 of the enclosure cylinder 100 produces a synergistic action of the compressed fluid in which the volume is contracted, and the above-described connection line 20 is in a free state depending on the flexibility. do.

Preferably, the pressure of the compressed fluid in the air pressure chamber P2 is formed at a low pressure so that the lowering operation of the bicycle saddle can be sufficiently produced according to the external force of the bicycle saddle coupling means 800, whereas the bicycle saddle coupling means ( 800), when the external force is removed, it must be stored as a compressed fluid having an expansion force that can sufficiently produce a lifting operation of the bicycle saddle.

When the height of the bicycle saddle is raised from a low state while riding a bicycle, in a "road-off" state in which no external force is applied to the bicycle saddle coupling means 800 (eg, a state in which external force is not applied to the saddle after rising from the saddle), the withdrawal means When the draw-out connection line 10 is drawn out using the 500, the control valve means 130 is opened as described above and the post head 220 and the seat post 200 are operated by the compressed fluid of the air pressure chamber P2. is lifted, and at this time, the height of the bicycle saddle by the connecting line 20 connected to the height adjusting member 230 of the inner cylinder 300 and the post head 220 is raised to a certain height according to the set length of the connecting line.

When the lifting operation of the seat post 200 is made in this way, the volume of the power pressure chamber P1 of the inner cylinder 300 is increased, so the oil fluid stored in the oil chamber C1 is the air pressure chamber P1 as described above. According to the opening of the control valve means 130 due to the action of the compressed fluid of

On the other hand, when the lifting or lowering operation of the seat post 200 is completed and the control valve means 130 is blocked, when the bicycle saddle is lifted and transported, the power pressure chamber P1 and the oil chamber C1 are blocked As the state is produced, the suction pressure is greatly increased in the power pressure chamber P1 due to the characteristics of the incompressible oil fluid, so the seat post 200 is maintained in a stationary state, and the upper and lower gap of the bicycle saddle is prevented.

According to the present invention configured in this way, the downward operation force of the bicycle saddle is produced by the hydraulic force of the inner cylinder 300, and the upward operation of the saddle is produced by the expansion force of the compressed fluid to store the compressed fluid. 200) can use a thin and light aluminum pipe or carbon pipe, making it possible to implement a lighter bike saddle height adjustment device.
