Description

  The present invention relates to an improvement of an infant tricycle, and more particularly to an infant tricycle in which a tricycle is folded to greatly improve a storage and storage space, and parts are shared to save resources.

  In many homes such as apartment houses and high-rise houses, a tricycle for infants is stored in the entrance of the house or stored at the entrance. In addition, every time a child plays a tricycle outdoors or in a park, take it out using an elevator or stairs, and after use, install and store it again at the entrance, entrance, or veranda. You are doing. Further, there is a case where a tricycle is loaded in a trunk of a car or the like and goes out for vacation.

  In such a case, even a tricycle for infants needs a certain amount of storage and storage space, so the entrances and entrances of houses that are limited in size are made small, and when entering and exiting the entrance. It can be an obstacle. Further, when a tricycle is stored together with various kinds of luggage in an automobile trunk or the like and goes out for a leisure trip, the bulkiness of the tricycle often becomes an obstacle. In addition, when carrying a tricycle, especially when carrying it up and down stairs, it is difficult for a young person to carry it, holding it with both hands, making it difficult to carry it in a stable form.

  In the past, the present applicant has been able to fold a tricycle in the past, greatly reduce its installation, storage space, etc., make it easy to perform its folding operation and change the form to the use state, We applied for a folding tricycle equipped with a unique mechanism, such as locking and enabling safe use, and obtained a patent right (Japanese Patent No. 3631669).

  On the other hand, in the conventional tricycle for infants, the tricycle is run by pushing the operating rod provided at the rear, but the crankshaft of the pedal integrated with the front wheel rotates during traveling, and the infant mounted on the pedal is rotated. Since the feet also rotate together, there is a risk of injury and there is room for improvement in safety. Also, there is known an infant tricycle in which a footrest step is provided separately from the pedal below the vehicle body frame when the child cannot pedal by himself (for example, Patent Document 1).
