Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a push car having an appearance formed in any form, such as a vehicle or an animal, for use in practicing walking, intellectual development, and emotional education for infants and children. .

[0002]

2. Description of the Related Art Conventionally, as a push wheel like the above example,
For example, there is a pushcart of a push type in which a gripper fixed to the rear end portion on the upper surface side of a car body is held by an infant's hand, and the infant's hand pushes the car body to travel.

[0003]

However, the above-mentioned push wheel is used when practicing walking for an infant. However, when the infant reaches a developmental stage in which the infant can walk alone, the push wheel becomes unnecessary, and the push wheel becomes unnecessary. Because it loses its value as a playground equipment,
There is a problem that the application is limited to walking practice only.

As another example of a push wheel, a push wheel that can be used is already on the market, but since the grip portion is also used as a backrest, the grip portion is removed or folded. This is structurally impossible. When unnecessary, a large storage space is required, so that there is a problem that handling of the push cart is very inconvenient.

In view of the above problems, the present invention allows the pusher to pivot up and down between the upright state and the horizontal state in the upright state and the horizontal state, so that one pusher can be used as a riding type or as a child depending on the growth or demand. An object of the present invention is to provide a passenger pushcart that can be selectively used as a pushcart type.

[0006]

According to the first aspect of the present invention,
A passenger push car that holds a grip portion attached to a vehicle body by hand and travels and moves the vehicle body in an arbitrary direction, wherein an end of the grip portion stands upright with respect to rear ends of the vehicle body. The vehicle is a passenger pusher pivotally connected to a vertical state between a state and a horizontal state and provided with a seat between receiving portions formed at both rear ends of the vehicle body.

According to a second aspect of the present invention, in addition to the configuration of the first aspect, the seat is a passenger pushcart in which the seat is mounted to be movable back and forth between the receiving portions.

According to a third aspect of the present invention, in addition to the configuration of the first aspect, a fixing means for rotating and fixing the grip portion to the upright state when the grip portion is rotated to the upright state is provided. It is a passenger push car.

According to a fourth aspect of the present invention, in addition to the configuration of the first aspect, a passenger is provided such that the grip portion rotated in the horizontal state and a seat attached between the receiving portions are lockable. It is a push wheel.

[0010]

According to a first aspect of the present invention, there is provided a passenger push car which rotates a grip portion pivotally attached to a vehicle body in an upright state, and pushes the push cart with a hand of an infant holding the grip portion to travel and move the push cart. Used as a pushcart for The grip portion is rotated to a horizontal state in which the grip portion is placed substantially horizontally with respect to the receiving portion, the infant is seated on a seat provided between the receiving portions, and the push cart is traveled and moved by the infant's own leg strength. Or, by pushing and moving a push cart carrying an infant with an adult's hand, it can also be used as a riding type playground equipment.

According to a second aspect of the present invention, in addition to the operation of the first aspect, the passenger push wheel moves the seat mounted between the receiving portions in the front-rear direction when riding, so as to respond to the growth of the infant. The slide can be adjusted to an arbitrary position on the receiving portion, so that anyone can ride on the vehicle regardless of body size and age as long as the weight can be carried. When pushing the hand, the seat is moved to the base end side of the receiving part, so when entering or leaving the infant between the receiving parts, when holding the gripping part with the hand of the infant, the seat does not get in the way, getting on and off The operation and the pushing operation can be easily performed.

According to the third aspect of the present invention, in addition to the operation of the first aspect, since the gripping portion is rotated and fixed in the upright state by the fixing means, the weight of the infant in the direction in which the gripping portion is tilted is reduced. It is possible to reliably prevent the gripping portion from tilting forward or rearward due to an impact given when the object is hit or collides with an obstacle, and the holding portion is maintained in an upright state. High safety can be obtained.

According to the fourth aspect of the present invention, in addition to the operation of the first aspect, the riding push wheel has a seat mounted between the receiving portion and the holding portion which is turned in a horizontal state at the time of riding. Since it is moved and locked, it is possible to reliably prevent the seat from falling off from the receiving portion. In addition, since the grip portion is rotated and fixed in a horizontal state, it is possible to maintain a riding state.

[0014]

According to the present invention, the grip portion is turned to the upright state, and the push cart is pushed by the hand of the infant holding the grip portion to move the push cart, and the grip portion is turned horizontally. The push cart is pushed and pushed by an infant's own leg strength or an adult's hand sitting on the seat to move the push cart, so that one push cart can be used as a push-cart or riding-type play equipment depending on the growth or demand of the infant. It can be selectively used, and can be used for purposes such as walking practice, intelligence development, and emotional education. In addition, by inclining the gripping portion in a horizontal state, the gripping portion becomes lower in volume than a conventional push-type push wheel, and handling and storage become very convenient.

In addition, since the seat is slid to an arbitrary position on the receiving portion according to the growth of the infant, anyone can ride on the seat, regardless of body size and age, as long as the weight can be carried. It can be used as a playground equipment with a wide application age and can be used for a long time. During hand pushing, the seat is moved forward, so when the infant is put between the receiving parts, when holding the grip with the hand of the infant, the seat is not in the way and the infant gets on and off and pushes. Can be easily performed.

Further, since the holding portion is pivotally fixed in the upright state by the fixing means, the weight of the infant is given in the direction in which the holding portion is tilted, or the holding force is given by the impact given when the infant collides with an obstacle. Since the part can be reliably prevented from tilting and the standing state is maintained, high safety can be obtained as a playground equipment for infants.

Furthermore, since the seat is moved rearward to the gripping portion which is rotated in the horizontal state and is locked, the seat is dropped from the receiving portion when the infant is seated or when the seat is moved rearward. Can be reliably prevented, and safety can be secured as a riding type playground equipment. Further, since the grip is pivotally fixed in a horizontal state, the riding state can be reliably maintained until the lock between the grip and the seat is released.
