に関するものである。[Detailed Description of the Invention] This invention attaches weight to one gear crank of the bicycle, and uses gravity to move the other pedal naturally in the forward and upward direction, making it easy to start the bicycle. It is related to the device that is intended to be used.

り(2)を付けたものである。Conventionally, the pedals of a bicycle are rarely in the appropriate position for starting, but when riding, at an intersection, at a traffic light, etc.
When the vehicle stops temporarily, the pedal must be adjusted to a position suitable for starting, which is very troublesome and inconvenient. Therefore, many people did not stop when they should have stopped, which was very dangerous from a traffic safety point of view.The present invention was made to eliminate this drawback. As shown in Figure 1, near the end of the left gear crank (1) in the forward direction of travel, place a moderately protruding weight (2) made of iron or other suitable material with an appropriate shape and weight. This is the one with the .
本発明は、このような構造上、ペダル(4)は常時はだ

である。したがって、左り足を地について乗車した場合
、ペダル(4)を、踏みやすく力も入れやすい位置なの
で、坂道や、重い荷物をのせているときでも、比較的、
楽に発進できるのである。Due to this structure, the present invention is designed such that the pedal (4) is usually in a position suitable for starting, but when it is not in a position suitable for starting, or when the pedal is temporarily stopped after riding, The operation is explained below using a drawing: (a) First, when getting on the vehicle, if the pedal (4) is not in the appropriate position for starting, move it forward 1 to 2 meters until the weight (2) sticks out. Structurally, the pedals (4) are naturally placed at a slightly tilted position, not directly above. Therefore, when riding with the left foot on the ground, the pedal (4) is in a position where it is easy to press and apply force, so even when riding on a slope or when carrying heavy luggage,
You can start off easily.
(ロ)乗車したまま交差点などで、一時停止した場合の

げるだけでよいのである。(b) When you temporarily stop at an intersection etc. while riding in a car, please operate the pedals within the dotted line from the top to the bottom of the rear in Figure 2.
If there is a pedal (3), the gravity of the weight (2) will cause the pedal (3) to naturally spin backwards and downwards, so place your right foot so that the pedal (4) is in a position suitable for starting. , all you have to do is lift it up.
(ハ)第3図の、少し前えに傾いた上から下の点線以内

用効果の大なる装置である。(c) If the pedal (3) is within the dotted line from top to bottom that is tilted slightly forward in Figure 3, the pedal (3) will rotate the wheel, Since it will not spin idly, use your right foot to rotate the pedal (4) backwards, and when the pedal (4) comes to the bottom, it will be in the same state as shown in Figure 2. If you then continue to lift your right foot, it will be easier to do so. This allows you to position it in a position suitable for starting. However, since the weight is attached only to the left side, physically the rotation of the pedals is unbalanced, but experiments have shown that there is almost no difference in gravity and there is no problem with driving. Therefore, the present invention is a device with great practical effects.
なお、右ギヤクランクペダルが、上之方向之来る実施態

In this case, it is easier to start the vehicle by turning the right gear crank slightly in the forward direction.
