Abstract

PURPOSE: To give a child a safe ride, and to enlarge storage volume or loading by fitting an auxiliary seat for child between the handle vertical rods of a bicycle, surrounding four peripheries with side walls, forming a bottom part out of a front bottom part for placing feet and a rear bottom part for placing a hip, forming the rear bottom part movable freely so as to move along the front side wall. CONSTITUTION: An auxiliary seat A is fitted between a pair of the vertical rods of a handle 3, and its four peripheries are surrounded by side walls 9. The bottom part of the auxiliary seat A is constituted of a front bottom part 11 for placing feet, a rear bottom part 10 for placing a hip part, and an auxiliary rear bottom part 14 under the rear bottom part 10. The rear bottom part 10 is formed to be rotatable so as to come into contact with the front side wall. It is thus possible to give a safe ride in a stable posture with the hip on the rear bottom part 10 and the feet on the front bottom part 11 in giving a child a ride, and attain a wider storage space with the rear bottom part 10 rotated so as to move along the front side wall in placing loading.

問題点があった。(Prior art) This type of child support seat for bicycles has a missing part on the left and right side walls for the child to put out both legs.The existence of the missing part weakens the side wall, making it difficult for the child to sit on the bicycle. There is a problem that safety is compromised when carrying a bicycle, and if the above-mentioned missing part is closed with a lid and used as a luggage basket, the vibration of the bicycle could cause the lid to open and the luggage could spill out from the opened missing part. There were also problems. In addition, with conventional child booster seats, the distance between the child's center of gravity and the center of rotation of the steering wheel increases when the child is seated, and the rotational moment that acts on the child when the steering wheel turns increases, making it difficult to operate the steering wheel. There was a problem that it caused children to feel anxious.

る。Next, when riding the bicycle 1 with a child on the child auxiliary seat 7, place the child's feet on the vestibular part 11 of the bottom member 12 and place the child's butt on the rear bottom part 10. Have the child grasp the grip part 25 with his or her hand. In this state, the child is extremely safe because the child is surrounded on all four sides by the continuous wall 9, and the child's feet are positioned on the front bottom 11, which is surrounded by the wall 9. It is extremely safe as it can prevent the child's shoes from falling off and also prevent the child's feet from touching the front wheels. Further, since the front bottom part 11 is lower than the rear bottom part 10, the child can sit in a comfortable posture without having to bend his/her knees significantly. When the person 1 drives the bicycle 1 in the above condition, the child auxiliary seat 7 is installed so that the front part of the rear bottom 10 is located above the horizontally extending rod 5b of the handlebar 3, as shown in FIG. Therefore, the driver (for example, the mother) should position both arms near the child (
This makes it possible to give the child a sense of security, and also allows the driver's mouth to be positioned close to the child's ears.

できる。Moreover, as mentioned above, the front part of the rear bottom part 10 is connected to the handle shaft 4.
Since the center of gravity of the child's weight can be brought extremely close to the center of rotation of the handle 3, the rotational moment acting on the child when the handle is turned can be reduced, making it easier to operate the handle. At the same time, the movement of the child when rotating the handle can be reduced, reducing anxiety and anger caused to the child. Furthermore, in the above state, when it is desired to place a relatively small article such as a bag or shopping, the rear sole 10 can be placed directly from the front into the article storage space 13 formed below the rear bottom 10, or the rear sole 10 can be temporarily moved forward. It can be rotated and stored.

In this state, the tip of the rear bottom part 10 is in contact with the front side wall 17, the rear bottom part 10 is held along the front side wall 17 by its own weight, and the peripheral side wall 9 and the auxiliary bottom member 14 are placed above the front bottom part 11 and the auxiliary bottom member 14. A large accommodation space surrounded by the peripheral side wall 15 is formed. Therefore, even fairly large loads can be loaded easily and stably.

Circumferential wall 9 or auxiliary circumferential wall 15
Alternatively, it may be arranged along the front bottom part or the auxiliary bottom member.

な声で小児に語りかけることができる便利性がある。In addition, when riding the bicycle 1 with a child on it with the main body part of the child support seat attached to the handlebar 3 as described above,
Both arms of the driver who operates the steering wheel 3 can be positioned close to both sides of the child, thereby giving the child a sense of security, and the tip of the driver's mouth can be brought close to the child's ears. This provides the convenience of being able to speak to children in a low voice even in noisy places.
