JP3038983U - Height adjustable remote control electric saddle - Google Patents

Abstract

(57) [Abstract] [PROBLEMS] The present invention makes it possible to adjust the height of a saddle of a bicycle according to the situation of a pedestrian even while traveling, so that the bicycle can be accelerated, normally run, or in a standby state. It reduces the load on your feet, allows you to ride comfortably on your bicycle, and secures your feet when you stop. According to the present invention, a bicycle saddle height is provided with an elevating mechanism equipped with a speed reducer powered by an electric motor, and is appropriately controlled by a remote control switch incorporated in a grip of a steering wheel even while the bicycle is running. By making it adjustable, the load on the foot is reduced and the leg force can be efficiently transmitted to the petal, and the feet can be secured safely by making it possible to wear the foot comfortably even when the bicycle is stopped.

Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to an electric saddle in which the height of a saddle of a bicycle or the like can be appropriately adjusted by operating a remote control switch incorporated in a grip of a steering wheel.

[0002]

[Prior art]

 To adjust the height of the saddle, loosen the tightening nut attached to the upper end of the seat post into which the leg tube of the saddle is inserted, or the bolt or nut equipped with a retractable tightening rod, and loosen the saddle. It was done by plugging and unplugging the leg tube.

[0003]

[Problems to be solved by the device]

 Conventionally, the height of the saddle is almost fixed once it is adjusted, and it has been considered troublesome to adjust it appropriately according to the situation of the rider. Therefore, if you set the height according to the running time, it will be difficult to reach your feet when you stop. Therefore, if it was set to an intermediate value, the knee joints were subject to unreasonable force during running, and I had to feel some discomfort. As a result, it became difficult to efficiently transmit the leg strength to Petal, and it was often seen that the person was standing upright when climbing a slope or accelerating quickly. On the other hand, when he stopped, he was in an unstable condition because he stretched his toes and supported the bicycle.

[0004]

[Means for Solving the Problems]

 The present invention provides an elevating mechanism equipped with a speed reducer powered by an electric motor on the leg tube of the saddle so that the height of the saddle can be appropriately adjusted with the user's hand even while riding a bicycle. Set it high to avoid excessive force on the knee joints, and use efficient leg force as when rowing in a standing position to enable labor-saving driving, and when stopping, lower the saddle so that you can comfortably wear your feet. Therefore, it avoids an unstable posture during standby, secures safety, and reduces the uncomfortable burden on the legs.

[0005]

[Embodiment of the invention]

 Hereinafter, embodiments will be described with reference to the accompanying drawings. When trying to ride a bicycle equipped with the electric saddle of the present invention, the saddle 10 is usually in a lowered position at first, but when it is in a high position, the remote control switch 13 is turned to the front to lower the saddle. If you get on, you can easily get out. Then, when accelerating, the handle grip 13 is turned clockwise to raise the saddle 10 and return it to the neutral position at an appropriate height, whereby the height is fixed. In normal driving, it is safer to ride by adjusting it to a slightly lower position than when accelerating, taking into consideration measures in the case of an emergency. When you stop at a traffic light etc., if you lower the saddle in advance and stop it, you can comfortably reach your feet, so you can secure your foot stability even when waiting.

At the time of a sudden stop, when the handle grip 13 is fully turned to the front, the motor 19 starts to rotate in the descending direction, but the Bowden wire 15 is continuously pulled and the gear of 24 of the reduction gear is disengaged so that the gravity is released. This allows the saddle 10 to drop to the lower limit and safely stop the bicycle.

The electric saddle of the present invention is fixed in the vertical direction when the motor is stopped by the speed reducer including the worm gear 26, and in the left and right rotation directions, a pair of protrusions 30 attached to the leg pipe 11 of the saddle and it. It is fixed by the groove of the seat post 12 which receives the. The height of the saddle is adjusted by selecting the up, stop, down, and quick descent by the remote control switch 13 incorporated in the grip of the steering wheel.

Upper and lower limits are set for height adjustment, and safety is ensured by stopper switches 17 and 18, respectively.

[0009]

[Effect of the invention]

 As described above, the variable height remote control electric saddle of the present invention is useful for realizing labor-saving, safe and comfortable running of the bicycle. If the ease of use and convenience of bicycles are reconsidered by reducing the burden on the legs, it is expected that demand for bicycles will continue to grow, as a vehicle that is expected to save energy, cause no pollution, and improve health.

Furthermore, if the adjustable range of the vertical adjustment of the saddle can be made slightly larger, labor-saving driving with a high line of sight becomes possible, and comfortable driving is effective in eliminating stress for modern people living in a stressed society. Target.
