Description

[Detailed description of the device] [Industrial applications]

 The present invention relates to a tricycle in which a child can play continuously within a certain range by fixing the traveling angle of the tricycle to both right and left.

[0001]

[Prior art]

 In the past, infant tricycles (hereinafter referred to as tricycles) have been popularized as vehicle toys that are played once during the growth process. This is done with friends and parents playing, but in traffic conditions such as the city where there are many automobiles, it is not possible for only one infant to play on a tricycle unless there is a large park. There are many risk factors not only when playing with friends but also with parents, so even if parents are small, it is safe to play tricycles in their home garden or indoors. It is common for households to play different ways.

[0002]

[Issues to be solved by the device]

 Tricycles are the first vehicle toys that a toddler rides alone and play by freely controlling the direction, and are especially preferred by boys. It However, in order for an infant to be able to play while pedaling alone on a three-wheeled vehicle, it was not easy for a parent and an adult to play and teach alone so that the child could ride around and enjoy themselves. Especially in the early stages, it is difficult to operate the steering wheel while operating the pedals, and in a small garden or room, you may immediately hit something, which will interrupt your play, resulting in continuous and smooth movement. I couldn't enjoy playing with cars.

In the suburbs where traffic conditions are not so severe and there are many sites and spaces where you can play, even a single infant and friends can easily practice tricycles and play vehicles. However, single-player play can be done early on, but in a city with a lot of cars, playing outside has many risk factors, so in many households it is late to give a tricycle to infants, In addition, even if you give it, even though you think that it is a bad idea, you can avoid playing outside under severe traffic conditions and play in the small garden or room at home. Not only that practice but also sufficient practice and play in a wide area is not possible, so the time when one can play vehicle alone will be late, which was a terrible thing for infants. Also, even if you play tricycle indoors, it is done in a space that is not large, and in addition to pedaling and pedaling, you often push and play, but in that case, it is not a steering wheel, usually tricycle Since the rear part and the backrest are pushed, the steering wheel becomes useless, and since he is not good at operating the steering wheel, he immediately hits a wall or furniture, so he can play around continuously. There were drawbacks and inconveniences that I could not do.

[0004]

[Means for Solving the Problems]

 In order to eliminate the drawbacks and inconveniences of the conventional tricycle play described above, the present invention allows an infant to continuously ride or push the tricycle alone in a small space, in addition to riding and playing. In order to make it possible for the parent to lock the steering wheel to the left or right in a fixed direction, it locks on the connection part of the body frame and the steering wheel so that it can play around by turning within a certain range. The tricycle has a pin lock and a lock screw hole, and a hand-held lock mechanism that locks and locks by inserting a lock screw pin rod into it.

[0005]

[Action]

 A lock screw hole (10) that fits the lock pin hole (9) that connects the handle shaft (3) and the body frame (4) to the upper face of the connecting shaft tube (5) from the connecting shaft plate (3) Two handle shafts (5) are provided on the right and left sides of the movably connected connecting shaft tube (5), and lock pin screws (11) are inserted into and engaged with the lock pin holes (9). If you want to lock and lock the angle to either left or right, simply tilt the handle (1) to the desired angle, align the lock pin hole (9) with the lock screw hole (10), and then insert the lock pin screw (11). The handle (1) can be fixedly locked at any angle on the left or right.

[0006] Therefore, when a tricycle with the handle (1) angle locked in this state is given to an infant and allowed to play, the handle (1) can be operated only in the locked direction regardless of whether the pedal is pushed or played. Since it does not work, even if you play naturally in a small garden or room with the result of rolling around within a certain range, you can play continuously without immediately hitting walls or objects and interrupting play. You can play without having to worry about your head going in a crazy direction if you take your eyes off. Furthermore, the lock pin screw (11) is a screw type so that it cannot be easily removed by the force of an infant, and when changing the handle angle, simply replace one lock pin screw to move the handle to the left or right. Can be fixed and locked.

【Example】

 An embodiment of the present invention will be described with reference to a perspective view shown in FIG. 1, an exploded perspective view of an essential part shown in FIG. 2 and a plan view of an essential part of a lock use example shown in FIG. The structure of a tricycle consists of a handle shaft plate (2) attached in the middle of the handle (1), a U-shaped connecting shaft plate (3), and a connecting shaft pipe (5) attached to the end of the body frame (4). ) Are fitted together, and one connecting shaft rod (7) and a split pin (8) are movably connected to a shaft hole (6) provided in the central part of the connecting part, The U-shaped connecting shaft plate (3) that forms the portion is provided with a lock pin hole (9) in the center front portion of the upper surface, and the connecting shaft pipe (5) of the vehicle body frame (4) has a shaft on the upper surface thereof. The lock pin hole (9) and the lock screw hole (10) are connected to a connecting portion formed by fitting two lock screw holes (10) and (10) slightly forward and to the left and right of the hole (6). This idea is constructed by combining the lock pin screws (11) that are inserted when the handle (1) is fixedly locked. .

In the embodiment, one lock pin hole (9) is provided in the connecting shaft plate (3), and two lock screw holes (10) (10) are provided in the connecting shaft tube (5). Although the type is shown as an example, the combination may be reversed and the lock pin hole (9) may be two and the lock screw hole (10) may be one combination. It is a work. Also, the lock pin holes (9) (9) and the lock pin screw (11) are threaded respectively to prevent them from coming off easily, but it is not necessary to use a screw combination as long as it can be firmly locked. The handle can be locked either to the left or right, but if a lock pin hole is also provided in the center to allow a straight-moving fixed lock, the infant can rest on the backrest. It is convenient to keep the steering wheel straight when the parent pushes with a long pusher. In addition, there is a type that has a protective cover at the connecting part for safety, but in this case, the protective cover also has an insertion hole that fits the lock pin hole (9) part provided on the connecting shaft plate (3). Can be solved by providing.

[Effect of device]

 The tricycle of the present invention can lock the steering wheel angle to either left or right with one lock pin screw, so it can be fixed when the parent is busy and can not reach the eyes all the time, or when playing in a limited narrow space or garden. When you want to play a vehicle at the location, tilt the handle to the left or right and then insert the lock pin screw after aligning the lock pin hole and the lock screw hole.The handle angle is easily fixed and locked. , Even if an infant rides or pushes it, it will play around continuously within a certain range, so it will not hit the wall immediately and the play will not be interrupted. You don't have to worry about going there, so you can play with peace of mind.

[0010] In addition, playing as a toy that moves before giving a tricycle is a so-called rattling push car toy play, in which animals and the like rattling when an animal moves in conjunction with a four-wheel car with a pusher, and a car with an engine-type car Since a tricycle is often given to the next stage of riding toys that straddle the legs, parents can use this locking mechanism to turn the tricycle to the left or right even if the infant cannot get into the tricycle from the beginning. Then, even if you can not ride a tricycle immediately, infants can push around within a certain range and play around with the experience of pushing and pushing toys and riding toys, and by doing so, you can get used to the tricycle quickly. As a result, you can quickly learn how to ride alone. In addition, recently, there have been provided toys for tricycles that have toys that move or ring in conjunction with the wheels of the tricycle.If the present invention is applied to tricycles equipped with these toys, it will be even more effective for infants. It is a device that can raise interest and interest. Furthermore, since this lock mechanism is extremely simple and simple, it can be operated and set at low cost, so there is almost no burden on parents.
