And, the back structure of the saddle is wide for supporting the weight of buttocks.

A bicycle saddle combined with springs to a frame of a bicycle works as a cushion.

The bicycle saddle of a related art should support the weight of a person riding a bicycle (hereinafter called rider). Besides, the front part of the saddle is narrow for making a space for moving both legs to rotate the pedals, while the back part is fabricated wide for supporting the weight of a human body.

Namely, parts supporting a hipbone and a thighbone and another part supporting the perineal region are fabricated to the contrary of a human structure, distributing the weight properly. Therefore, the perineal region where sensitive human organs such as the anus, genital, and the like are located are locally oppressed by the force supporting the weight on the saddle.

Accordingly, it is very inconvenient for riding a bicycle having the bicycle saddle of the

related art because poor ventilation makes the crotch sweat. Moreover, the sexual nervous system may be damaged by the oppression on the genital region of a human body.

Disclosure of Invention Accordingly, the present invention is directed to a bicycle saddle that substantially obviates one or more of the problems due to limitations and disadvantages of the related art.

The object of the present invention is to provide a bicycle saddle which enables to support the weight of a rider mainly by the hipbone and thighbone by means of reducing the force oppressing the genital region greatly as well as to provide excellent ventilation, thereby minimizing the bad effects of the rider and providing a comfort riding.

Best Mode for Carrying out the Invention Reference will now be made in detail to the preferred embodiments of the present invention, examples of which are illustrated in the accompanying drawings.

The present invention, which relates to a saddle used for a bicycle, a health machine or

a riding equipment similar to the bicycle, will be described concretely about a bicycle saddle as an example.

The present invention as shown in Fig. 3 to Fig. 3, includes a variable saddle part 3, a peripheral saddle part 2 which is installed at a saddle support attached to a bicycle frame for supporting the weight of a bicycle rider, and a level adjuster 5 which adjusts the height of the variable saddle part from the peripheral saddle part.

An outer form of the peripheral saddle part 2 has a general shape of a bicycle saddle.

And, a long groove 6 is formed at a central part of the peripheral saddle part which is contacted with the perineal region The variable saddle part 3 is comprised of respective variable saddle parts 3-1 to 3-4.

Each of the respective variable saddle parts is installed in the central groove 6 of the peripheral saddle part and connected to adjust its height independently from the peripheral saddle part with the level adjuster 5.

A front part 23 of the peripheral saddle part 2 has a sharp end. And, wing parts 21 and 22 are formed in the rear part of the peripheral saddle part 2. An elastic part is formed on a frame of the peripheral saddle part made of a substance of which stiffness is high, providing elasticity against the weight of a rider. Partitions 24 of which centers are penetrated are formed in the central groove 6 of the peripheral saddle part 2 to house the respective variable saddle parts 3-1 to 3-4.

The wing parts 21 and 22 of the peripheral saddle part have smooth curved shape bending downward. And, exhausting holes 8 are formed to drain out water from the central

groove 6 of the peripheral saddle part. Elastic part is also attached to the frame of the variable saddle part 3.

Under the front of the peripheral saddle part, a bolt 11 is embedded in the frame to be coupled with a spring which is connected to the support of a bicycle. And, joint grooves 12 are formed in the rear part of the peripheral saddle part to be couples with a bicycle frame through a spring.

The respective variable saddle parts and peripheral saddle part, as shown in Fig. 4 to Fig.

10, are coupled by the level adjuster 5.

The level adjuster 5 may be constituted with bolts, level, linking apparatus and the like.

Instead, the present invention introduces a constitution which enables to adjust the height successively in use of a screw.

In a first embodiment of the present invention, as shown in Fig. 4, Fig. 6A, Fig. 7A, Fig.

11, and Fig. 12, the level adjuster 5 includes female screws 31 as a first screw part formed in the respective variable saddle parts 3-1 to 3-4 and male screws 32 as a second screw part coupled with the peripheral saddle part to rotate freely to the screw-revolving direction.

The female screws 31 are formed in a frame 30 of the variable saddle part 3. And, the male screws coupled with the female screws 31 are connected to another frame 34 of the peripheral saddle part.

A screw 35 is formed in the upper part of each of the male screws 32. A driver groove 36 is formed in the lower part of the shaft of the respective male screws 32. And, a flange

37 is formed in the middle lower part of each of the male screws 32. Each of the male screws 32 is fixed to a lower support 40 attached by a set screw 39 wherein a groove is formed in the lower part of the frame 34 of the peripheral saddle part and a buffer washer is inserted on the flange 37 of the male screw 32. The lower support 40 supports the weight. The female screws are lift up or down by revolving the male screws with a driver and the like.

In this embodiment, a cushion substance 29 surrounds the frame 30 in which a nut of a female screw is embedded the variable saddle part, and another cushion substance 28 covers the upper part of the peripheral saddle part to give a rider on the saddle comforts.

When the height of the variable saddle part is adjusted by the level adjuster, balance springs 45 are installed at both sides of the respective variable saddle parts to make the variable saddle parts balanced. The balance springs are made of coil springs. A plate spring or coil spring may be installed near the screw parts.

Housing groove 46 for the balance springs are formed at the central groove of the peripheral saddle part and the bottom of the variable saddle part to install the balance springs at fixed locations.

Poor ventilation through the saddle probably make a rider sweat, which is prevented by forming air paths 7 to make air pass through between the sidewalls of the variable saddle part and peripheral saddle part and by forming an airway 9 to let air in a space 4 between the lower part of the variable saddle part and a bottom of the central groove of the peripheral saddle part. In this case, the airway 9 is closed with a stopper 10.

In a second embodiment of the level adjuster 5, as shown in Fig. 5, Figs. 6B, and Figs.

7B, the frames of the respective variable saddle parts 3-1 to 3-4 are divided into a first and second frame 52 and 51. The first frame 52 has a first screw part 53 to be coupled with the level adjuster. And, cushion springs 55 pushing the places between the first and second frames are installed.

A distance-limiting means, which couples the first frame with the second frame, controls the distance between the first and second frames not to displace over a predetermined interval as well as to adhere closely each other.

The distance-limiting means includes screw holes 56 formed in the first frames 52 and screw-coupled parts 57 which are coupled by set screws 58 through the screw holes 56.

Thus, the displacement between the first and second frames has a limitation over a predetermined distance but the screws are free to move within the predetermined distance through the screw holes. Therefore, once the first frames are forced by the weight, the force of the cushion spring 55 is driven to the second frame.

Spring-housing grooves for the cushion springs are formed in the first and second frames.

A first screw part in the variable saddle part is formed by a nut 53 embedded in the center of the first frame. A second screw part is formed in the peripheral saddle part. Male screws 32 of the second screw part are coupled with the frame 34 of the peripheral saddle part.

As explained in the description of the first embodiment, A screw 35 is formed in the upper part of each of the male screws 32. A driver groove 36 is formed in the lower part

of the shaft of the respective male screws 32. And, a flange 37 is formed in the middle lower part of each of the male screws 32. Each of the male screws 32 is fixed to a lower support 40 attached by a set screw 39 wherein a groove is formed in the lower part of the frame 34 of the peripheral saddle part and a buffer washer is inserted on the flange 37 of the male screw 32. The lower support 40 supports the weight. The female screws are lift up or down by revolving the male screws with a driver and the like.

In this embodiment, a cushion substance 29 surrounds the frame 30 in which a nut of a female screw is embedded the variable saddle part, and another cushion substance 28 covers the upper part of the peripheral saddle part to give a rider on the saddle comforts.

Besides, installation of balance springs 45 and formation of air paths 7 and an airway 9 are the same as explained in the description of the first embodiment.

Relating to a following embodiment of a level adjuster, as shown in Fig. 11 and Fig. 12, the head of the male screw has a shape of butterfly knob 44. A hole 43 to have the butterfly knob 44 pass through is formed in the lower support 40. Another constitutions are the same as is in the above explanation. Therefore, it is very convenient to adjust the level by revolving the butterfly knob with a bare hand without a screw-driver or a pin.

In the next embodiment of a level adjuster, as shown in Fig. 13 and Fig. 14, a rail 70 having a guiding groove 72 to make a head 71 of a male screw revolve is embedded in a frame 73 of the variable saddle part. And, a nut 75 is embedded in another frame 74 of the peripheral saddle part. A penetrating hole 76 or a driver groove (not shown in the drawing) is formed horizontally at the end of a male screw 77 coupled in the above

structure. A bolt head 71 of the male screw 77 is coupled with the guiding groove 72, and a screw part 78 of the bolt is coupled with the nut. The bolt head is revolved in the guiding groove by rotating the bolt with a driver, a pin 79, or the like, thereby controlling the interval between the variable and peripheral saddle parts by the screw part including the bolt and nut. After the adjustment, the height is fixed by fastening a nut 80.

The cross-sectional view of the rear part of the saddle is the same as is shown in Fig. 8 and Fig. 9, and, the other cross-sectional view of the front part is the same as is shown in Fig. 10.

The numeral 100 in Fig. 9 indicates an example of a saddle-coupling means which is coupled with the bicycle frame. The numeral 101 indicates a coupling spring, one end of which is coupled with the coupling hole 12 in Fig. 8 and the other end of which is coupled with the bolt 11 in Fig. 10. In this case, the other end of the coupling spring has a shape of ring.
