Description

Divided bicycle saddle following the movement of the pelvis {STRUCTURE OF DIVIDED BICYCLE SADDLE INVERSELY MOVING UP / DOWN BY LEG'S MOTION}

The inventors of the present invention are divided into two types of bicycle saddle device, which is divided into a first saddle and a second saddle, and the center of the bicycle saddle is separated from the center to minimize the impact on the hips and the waist. It reduces fatigue and minimizes friction and shock when pedaling as the front part of the bicycle saddle separated by the first saddle and the second saddle moves up and down according to the movement of the pedal foot. It will provide the effect of minimizing pain.

In addition, the bicycle saddle divided into the first saddle and the second saddle, when the pedal is pressed, the front part of the saddle is turned down to each other down and the back is supported, so the maximum propulsion of the leg is transmitted to exert high driving force. The bicycle saddle, which is divided into the first saddle and the second saddle, has a simple and solid shape, provides a stable driving environment and reduces the cost of maintenance. The bicycle saddle divided into the first and second saddles By constructing a moving guide in which the rollers of the first saddle and the second saddle move in the saddle frame extension part and the extension part fixed to the saddle frame, the movement of the pelvis is depicted according to the movement of the left and right legs. It provides a bike saddle with maximum force to pedal on the legs, thus minimizing the impact on the pelvis and hips.

Conventional bicycle saddles simply support the hips, causing severe fatigue on the legs and hips due to long road trips or shocks caused by prolonged driving and friction with the saddle. This provided a bad perception of use.

In particular, the bicycle saddle adopted in the conventional high-priced equipment has a saddle with a V-shaped center portion, but the above-mentioned effect is insufficient for driving on long curved roads or for a long time. A cushion or gel-type silicone cushion cover may be used, but this also reduces the force pushing the bicycle pedals to the legs due to excessive cushioning.

Therefore, there is a need for a saddle structure and design in a form that does not reduce the force on the pedal due to excessive shock absorption even on a severe curved road or a long running.

Accordingly, the present invention has been made to solve the above conventional problems,

An object of the present invention according to the movement of the foot and the foot stepped on the pedal to enable a smooth shock absorption and effective force transmission without using a saddle with a spring or a gel type cushioning material conventionally The purpose is to provide a two-part bicycle saddle structure, in which the front part of the saddle moves up and down and both sides are twisted up and down along the leg movement to ensure a stable driving environment.

According to another object of the present invention, the first and second saddles move up and down in opposite directions as the seesaw as the front saddle of the two-part bicycle moves on the legs, and simultaneously the foot and the hips step on the pedals. To provide an ergonomic two-segment bicycle saddle having a structure close to the legs and hips.

Still another object of the present invention is that the front end of the first saddle and the second saddle moves up and down like a seesaw by means of a seesaw connection device provided at the front end of the first saddle and the second saddle, The roller connected to the rotating shaft support frame is rotated along the saddle moving guide, to provide a saddle structure that follows the movement of the lower pelvis caused by the movement of the left and right legs rather than a simple rotation.

In order to achieve the problem to be solved by the present invention, the present inventors moved up and down the bike splitting saddle device,

First and second moving guide grooves for coupling the rotating shaft support frames 105-1a, 105-1b, 105-2a, and 105-2b of the first saddle 105-1 and the second saddle 105-2 to one side. Rotating shaft support frames 105-1a, 105-1b, 105-2a and 105 formed on the lower side of the first saddle and the second saddle separated from each other in the moving guide groove by forming (106-1, 106-2) -2b) is connected to the saddle rear rotation shaft shaft (106-1c, 106-2c) through the moving guide roller (106-1a, 106-1b, 106-2a, 106-2b),

And the pinion gear (100-3b) and the pinion gear rotating shaft (100-1a) for connecting the first spur gear (100-1b) and the second spur gear (100-2b) to operate as a seesaw,

A driving bevel gear housing 101 incorporating the bevel gears of the first spur gear, the second spur gear, and the pinion gear 100-3b;

And the support housing 102 for supporting the housing 101 in the lower side,

The bifurcated bicycle saddle apparatus, which twists and moves up and down according to the present invention including the above configuration, can obtain the following effects.

First, the bicycle saddle divided into the first saddle and the second saddle has a center-separated form to minimize the impact on the hips and the waist, thereby reducing fatigue on long roads or long running.

Second, the front part of the bicycle saddle, which is divided into the first saddle and the second saddle, minimizes friction and shock when pedaling as the foot moves up and down according to the movement of the foot. It will provide an effect.

Third, the bicycle saddle separated into the first saddle and the second saddle, when the pedal is pressed down the front part of the saddle and the back is supported by the maximum power of the leg to deliver a high driving force.

Fourth, the bicycle saddle, which is divided into the first saddle and the second saddle, provides a stable driving environment in a simple and solid form and reduces the cost of maintenance.

Fifth, the bicycle saddle separated into the first saddle and the second saddle constitutes a moving guide connected to the extension part and the end of the extension part in the saddle frame, thereby preventing the left and right side shaking caused by the movement of the left and right legs. You can do it.

It characterized in that it comprises a lower support frame (103-1, 103-2) for supporting the first saddle moving guide (106-1) and the second saddle moving guide (106-2).

Each component is coupled to the saddle frame as described above, and to explain the operation principle, the first saddle 105-1 of the first saddle 105-1 descends by the movement of the foot pedaling down the first saddle. The seesaw shaft 107-1 rotates clockwise (when viewed from the first saddle), whereby the first saddle retracts backwards by the radius of the saddle seesaw shaft at the point where the front part of the first saddle passes the lowest point. Done. The second saddle connected to one side of the first saddle seesaw shaft 107-1 diagonally while retreating backward as the front part of the first saddle rotates clockwise as described above is connected to the first saddle seesaw shaft 107-1. 1 The spur gear 100-1b rotates clockwise while the pinion gear 100-3b rotates counterclockwise (when viewed from the saddle front) and the second spur gear 100-2b counterclockwise. The front part of the second saddle in the counterclockwise direction by the second saddle front-side forward shaft connecting device 107-2 connected through the second saddle seesaw shaft as it rotates (if seen from the first saddle). As you climb up, you will retreat.

As described above, the first saddle seesaw shaft 107-1 and the second saddle connected to the first spur gear 100-1b and the second spur gear 100-2b connected through the pinion gear 100-3b, respectively. By the seesaw shaft 107-2, the first saddle and the second saddle are twisted up and down and back and forth to each other, thereby allowing the driver to follow the movement of the foot on the pedal and smooth the pedaling according to the movement of the pelvis. Let's do it.

According to this principle, the front part of the saddle (front of the saddle) is twisted back and forth according to the movement of the pedal, which minimizes friction and shock caused by the pedaling movement, and at the same time transmits the leg to the pedal. Power is made to the maximum.

Accordingly, it is possible to have an advantage of not reducing the force on the pedal according to the movement of the foot and the pelvis of the pedal.
