Bicycle Saddle {BICYCLE SADDLE}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bicycle saddle, and more particularly, to a bicycle saddle having a pair of sheets for respectively supporting a buttock and a forehead for pressing a perineum in a conventional saddle.

Bicycle is one of the most popular means of transportation using manpower, and has been widely used in daily life for a long time. Especially, recently, the environment-friendly characteristics and the health promotion effect as a fitness equipment have attracted attention.

However, the saddle of the bicycle according to the related art ('10' in FIG. 1) is composed of a narrow triangle at the front and a wide triangle at the rear so that the user can smoothly perform the pedaling operation Therefore, the front part of the saddle ('10a' in FIG. 1, hereinafter referred to as 'front corner') is positioned between the both side femoral part and the buttocks of the user so as to be in tight contact with the perineal part of the user.

Therefore, it is inevitable that the front part of the saddle repeatedly presses the perineal part of the user during pedaling, and thus the blood circulation around the perineal part is not smooth, and when the bike is used for a long time, it causes skin damage due to erectile dysfunction or frequent friction .

SUMMARY OF THE INVENTION It is an object of the present invention to provide a bicycle saddle in which a pair of sheets each support the buttocks and the front sock is removed from the existing saddle.

It is another object of the present invention to provide a bicycle saddle which is adjustable in accordance with a user's body size or shape.

It is still another object of the present invention to provide a bicycle saddle capable of adjusting a slope of a seat to be suitable for a driving pattern such as a high-speed pedal or a downhill while the user is driving without getting off.

It is still another object of the present invention to provide a bicycle saddle in which a pair of sheets can be independently lifted and lowered for flexible operation during pedaling.

In order to solve the above technical problems, a bicycle saddle according to the present invention includes a pair of seats which support the buttocks, respectively, and which have no part to be rubbed against the inside of the perineals or thighs; A sheet fixing table for supporting the sheets, respectively; And a base to which a seat post is connected at a lower portion and the seat fixing table is provided at an upper portion.

The upper surface of the sheet is preferably formed of an ergonomic curved surface so that the buttocks can be closely contacted.

Further, it is preferable that the distance between the pair of seat fixing tables is adjustable.

It is also preferable that the sheet is capable of adjusting the tilt in the front and rear direction.

Further, it is preferable that the seat fixing table is configured to be stretchable so that the pair of sheets can be independently lifted and lowered during pedaling.

Further, it is preferable that the pair of sheets are rotatable from side to side with the sheet fixing table as an axis.

According to the present invention, the pair of sheets each support the buttocks, and in particular, it is possible to avoid the pressing of the perineal region by removing the front edge from the existing saddle, and the blood circulation around the perineal region can be smoothly performed and the skin can be protected.

In addition, the seat can be ergonomically formed so that stable seating can be achieved.

Particularly, since the separation distance between the pair of sheets can be adjusted and the body can be rotated to the left and right, a custom saddle can be sought according to the body size or shape of the user.

In addition, the slope of the seat can be adjusted so that it is suitable for a driving pattern such as a high-speed pedal or a downhill while the user is driving without getting off.

In addition, since a pair of sheets can be lifted up and down independently while acting as a whole cushion, flexible operation is possible in the pedaling.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a configuration and an operation of an embodiment according to the present invention will be described in detail with reference to the accompanying drawings.

2 to 5, an embodiment according to the present invention includes a pair of sheets 110, a sheet fixing table 120, a base 130, and a seat post 140.

It will be appreciated that the sheets 110 are configured in pairs to support the buttocks, respectively. Particularly, the seat 110 has no portion corresponding to the front seat ('10a' in FIG. 1) in the existing saddle. That is, the seat 110 according to the present invention intentionally excludes a portion that presses the perineum portion (a portion that rubs inside the thigh).

In addition, the seat 110 has an ergonomic design such that the outer edge and the rear edge of the seat 110 are curved upwardly so as to surround the buttocks, and the inner edge and the front edge of the seat 110 are lowered. Therefore, a stable sitting can be achieved while wrapping the buttocks, and the inside of the thighs is not rubbed.

The seat fixing table 120 is a component for supporting the seat 110. The seat fixing table 120 is formed with an engagement portion 121 through which the base 130 passes, A second tube 123 having a larger diameter than the first tube 122 is provided. A spring 124 is provided between the first tube 122 and the second tube 123 to allow the sheet holder 120 to expand and contract. That is, the pair of seat fasteners 120 can be separately expanded and expanded in length, and the pair of sheets 110 supported by the seat fasteners 120 are individually raised and lowered. A guide pin 125 is screwed to the first tube 122 to guide the expansion and contraction of the seat fixing table 120 and a guide hole 123a is formed in the second tube 123, The guide hole 123a moves along the guide pin 125 to guide the sheet fixing table 120 to expand and contract, that is, to ascend and descend the sheet 110. [ A plurality of screw holes 122a to 122c to which the guide pins 125 are coupled to the first tube 122 are provided in the horizontal direction, In and out. This will be described later.

Of course, the diameter of the first tube 122 may be larger than that of the second tube 123, or the seat fixing base may be stretched or lifted by another known method.

Also, in this embodiment, the engaging portion 121 of the seat fixing table 120 is formed in a hollow cylindrical shape, and the position of the engaging portion 121 can be moved along the base 130. That is, the seat post 140 can be changed in position from side to side with reference to the seat post 140. This is for the purpose of adjusting the spacing between the pair of sheets 110 according to the body size of the user (especially the sciatic space) to be optimized. A protrusion 121a is formed on the inner circumferential surface of the coupling part 121. A guide groove 133 corresponding to the protrusion 121a is formed in the base 130 so that the protrusion 121a is inserted into the guide groove 133 to adjust the separation distance between the sheets 110 (see arrows in Fig. 4). After the spacing distance is adjusted in this way, the user tightens the fixing screw 132 to the screw hole 131 formed in the coupling part 121 and the base 130, As shown in Fig. A plurality of screw holes 131 are formed in the base 130 so that the interval between the sheets 110 can be easily adjusted as needed. In the present invention, a method of adjusting the interval between the pair of sheets 110 may be performed by other known methods. Particularly, when the bolt member is rotated in one direction by applying the ball screw method, the pair of sheets may be moved away from each other, and when the bolt member is rotated in the other direction, synchronous driving may be performed so as to be close to each other.

Also, the screw hole 131 may be formed on the back surface of the base 130 so that the fixing screw 132 may be fastened to the back surface so that the fixing screw 132 is not exposed on the front surface for the aesthetic sense. Alternatively, the fixing screws 132 may be tightened together by fastening them together on the front surface and the back surface.

6 is a horizontal sectional view of the sheet fixing table 120 according to the present invention. As shown in the drawing, a first tube 122, a second tube 123, and a spring 124 are provided. In the front and rear sides of the first tube 122, three screw holes 122a to 122c And a guide pin 125 is fastened to one of the screw holes 122a to 122c. A rubber pad 126 for preventing friction is interposed inside the head of the guide pin 125. The second tube 123 is moved up and down from the outside of the first tube 122 by the guide pin 125 and the screw holes 122a to 122c. A protrusion 122d is formed in the outer circumferential surface of the first tube 122 and a groove 123b is formed in the inner circumferential surface of the second tube 123 to fit the protrusion 122d, Thereby guiding the tube 123 to move up and down outside the first tube 122. And both the sheets 110 are opened or vice versa depending on which threaded hole 122a to 122c the guide pin 125 is fastened to.

The adjustment of the inclination of the sheet 110 will be described with reference to Figs. 7, a cylindrical portion 141 is provided at an upper portion of the seat post 140, and a center of the base 130 is positioned in the cylindrical portion 141. Further, a bearing is interposed between the seat post 140 and the base 130 for smooth rotation. In particular, a plurality of tilt adjusting projections 134a to 134d are provided in the center of the base 130, and the fork 153 is provided on the lever 150 to engage with any one of the tilt adjusting projections 134a to 134d . The fork 153 is formed with an insertion groove 153a into which the tilt adjusting projections 134a to 134d are inserted. Also, when the base rotates, springs 135 and 136 that are elastically deformed are provided, so that elastic restoration can be performed when an external force is removed. A plurality of click grooves 134e are formed on the outer circumferential surface of the base 130 in order to provide a clicking feeling when the tilt is adjusted. A plurality of click grooves 134e are formed in the outer circumferential surface of the base 130, A spring 143 is provided.

Fig. 7 shows a state in which the fork 153 of the lever 150 is engaged with the first adjusting projection 134a, which is generally a horizontal state of the seat.

8, when the lever 150 is pulled out, the fork 153 is pulled out of the first adjusting protrusion 134a, so that when the user changes the speed from the normal driving to the high speed driving, Is rotated in a counterclockwise direction by a predetermined angle, whereby the front portion of the seat 110 is bowed at a predetermined angle. In this state, the fork 153 of the lever 150 is inserted into the second adjusting projection 134b formed at the upper portion, and the base 130 is fixed in a state where the inclination is adjusted. If the front portion of the seat 110 is bowed forward as compared with the rear portion, it is very advantageous in high-speed pedaling. Therefore, it can be seen that the third adjusting projection 134c is formed so that the third adjusting projection 134c can be further advanced. Also, in this tilt adjustment, the first spring 135 is tensioned and the second spring 136 is compressed. Accordingly, when the lever 150 is pulled forward during traveling, the seat 110 is returned to its original position horizontally by the elastic restoring force of the first spring 135 and the second spring 136, It can be fixed by being inserted into the adjustment projection 134a. As described above, according to the present invention, the inclination of the seat 110 can be adjusted while running without getting off. When the lever 150 is pulled out and then the force is removed, a spring 152 is provided to return to the original position.

When the fork 153 of the lever 150 is inserted into the fourth adjusting protrusion 134d formed at the lower portion when the bicycle is downhilled and the front portion of the seat 110 is fixed to rise above a predetermined angle with respect to the rear portion, (See FIG. 9).

Referring to FIG. 10, the embodiment of the present invention is configured so that the seat 110 can rotate left and right about the first tube 122 of the seat fixing table 120. 10A shows a state in which the sheet is rotated outward from the normal state 110A (a state in which the sheet is fanned 110B), FIG. 10B shows a state in which the sheets are rotated inward ). A method of rotating the sheet 110 in this manner will be described with reference to Figs. 2 and 4. Fig.

The sheet 110 is in a normal state when the guide pin 125 is constrained to the screw hole 122a positioned at the center among the plurality of screw holes 122a to 122c of the first tube 122. [ In this state, the guide pin 125 is released to rotate the second tube 123 with respect to the first tube 122, and then the guide pin 125 is inserted into the screw hole 122b positioned on the outer side of the first tube When the sheet 110 is tightened, the sheet 110 is fixed in the opened state.

In addition, when the guide pin 125 is fastened to the screw hole 122c located inside the first tube, the sheet 110 is fixed in a tucked state.

In this way, the seat can be configured to be rotatable in and out, and can be used in a condition suitable for the user's body structure and size.
