Description

Remote control device for bicycle handle end

This creation relates to the remote control of the bicycle, especially at the handle end of the bicycle.

Generally, riding a road bike will lean forward compared to a normal bicycle. The standard of the height of the seat cushion is to use the heel to step the pedal to the lowest point. At this time, the knee still has a little bending, and the foot is easy to force the best cushion height. On the downhill section, please refer to Figure 1. The human body will lean forward. At this time, if the height of the seat cushion is higher from the ground, the angle of the body leaning forward is larger, and the center of gravity P of the human body falls in front of the bicycle and swoops forward, which is easy to cause the bicycle. It is quite dangerous to turn over. Therefore, the rider usually lowers the seat tube in advance to adjust the center of gravity to maintain a lower riding posture. When riding on the uphill section, please refer to Figure 2, the angle of the rider's body in contact with the ground. The center of gravity P of the body will move toward the rear, and the front wheel will go up. In particular, the greater the slope of the upward riding, the more dangerous it is. In addition, when the seat tube of the bicycle is too low, the riding position will be caused, and the strength of the leg will not stretch, causing the riding. Unpleasant, it is more likely to cause muscle and joint damage and fatigue, so the rider will adjust the height of the bicycle cushion in advance with different road conditions.

As for the Republic of China Taiwan M552458 patent number "bicycle seat tube", one end of the bicycle seat tube is provided with a hexagonal bow fixing portion, and the seat bow fixing portion includes a receiving portion, an adjusting member and a first clamping member. , the second clamp firmware and the locker, the receiving part is provided with a hexagonal one The accommodating hole is configured by an adjusting member of a relative shape, wherein the adjusting member is disposed at a position other than the center of the adjusting member, and the first clamping member is disposed at one side of the variator hole to fix the seat cushion a bow and a second clamp are respectively disposed on the left and right sides of the seat fixing portion, and the second clamp is disposed on the other side of the displacement hole of the adjusting member to fix another bow of the seat cushion, the first The two clamps have a second positioning hole, the fastener is a bolt and a nut, the bolt passes through the first positioning hole of the first clamp, the displacement hole of the adjustment member and the second reinforcement of the second clamp Position the hole and screw it into the nut.

Thereby, when the adjusting member rotates with the accommodating hole at a multiple of 60°, the variator hole changes its up, down, left and right positions as the angle of the adjusting member changes, and drives the first clamp on the left and right sides thereof. And the second clamp firmware changes the relative front and rear positions, thereby adjusting the position of the bicycle seat cushion.

However, in the above-mentioned conventional technique, the rider must stop the height of the seat cushion of the bicycle, and then the nut is pulled out by a hexagonal wrench.
