Description

[Detailed Description of the Invention] Industrial Application Field This invention relates to a toy stroller in which a doll placed on the wheelbarrow moves part of its body when the wheelbarrow is driven.

Prior Art and Its Disadvantages Conventional baby cart toys are meant to be enjoyed simply by pushing the wheelbarrow around, and the dolls sitting in it are stationary and do not express any emotions or make any movements, so they are not susceptible to change. There were some flaws that made it lacking and uninteresting.

Technical Problems to be Solved In view of the above points, this invention is designed so that when a handcart is pushed and moved, the dolls riding in it express emotions such as joy or fear, or make movements, and the dolls change as they move. The aim is to provide a toy car that allows the user to enjoy the game.

Means for Solving Problems In order to solve the above problems, the toy stroller according to this invention is equipped with an air pressure generating means that operates as the wheels rotate when the wheelbarrow is being driven, and the doll placed on the wheelbarrow is It is equipped with a pneumatic drive means that swings a part of the body by applying air pressure from the pneumatic pressure generating means.

The handcart is provided with a space for installing a bellows between the doll accommodating part and the rear wheel axle, and the air pressure generating means is attached to a cam fixed to the rear wheel axle and in the installation space of the handcart, A pneumatic drive means is provided inside the doll's body, and the operating body reciprocates in response to the pressurization and depressurization from the bellows. , and a conversion member that converts the reciprocating motion of the movable body into a rocking motion of the movable portion of the doll.

Function When the wheelbarrow is run, the bellows are activated as the rear wheels rotate, generating positive and negative pressure. This positive and negative pressure is applied to the moving body within the doll, causing the moving body to reciprocate. This reciprocating motion is converted by the converting member into a rocking motion of movable parts such as the doll's legs, arms, or eyeballs.

Embodiment Next, an embodiment of this invention will be described based on the drawings.

The stroller toy according to this invention includes a wheelbarrow A,
It consists of a doll 7 placed on it, an air pressure generating means attached to the handcart A, and an air pressure driving means attached to the doll 7.

The handcart A has a space for installing a bellows between a rear wall 2 of a doll accommodating part (hereinafter simply referred to as accommodating part) 1 and an axle 5 of a rear wheel 4. This space for installing the bellows is formed by a side wall 1W extending rearward from the rear wall 2 of the housing portion 1.

The doll 7 housed in the housing section 1 has legs, for example.
It has movable parts such as arms or eyeballs that can express emotions such as joy or fear through movement. In the illustrated example, both legs 12 are attached so as to be swingable about their bases. In order to swing the legs 12 of this doll in conjunction with the running of the handcart, it is provided with pneumatic pressure generating means and pneumatic driving means AM. Next, its configuration will be explained.

First, the air pressure generating means includes a bellows 3 installed in a bellows installation space provided in the handcart A,
It consists of a cam 6 fixed to the axle 5 of the rear wheel 4. The cam 6 rotates the bellows 3 as the rear wheel 4 rotates.
Since the bellows 3 repeatedly presses and releases the pressure on the back surface of the bellows 3, the bellows 3 alternately generates positive pressure and negative pressure in the open tube 3a. The opening tube 3a of the bellows 3 passes through the rear wall 2 and projects to the inner surface of the rear wall.

Next, the pneumatic drive means AM is provided in the body 8 of the doll, and is pressurized or depressurized by the bellows through a connecting pipe 9 connected to the opening pipe 3a of the bellows 3 on the back of the doll. A cylinder 10, a piston 11 inserted into the cylinder so as to be able to reciprocate, and a piston 11 fixed to the inner end of a rotating shaft 13 provided at the bases of the left and right legs 12 of the doll, in a radial direction from the center of rotation of the rotating shaft 13. A cam 16 is provided with a protruding pin 14 at a position separated by a cam 16, which is rotatably connected to a bifurcated protrusion 15 formed at the end of the piston. The pins 14 of the cams 16 on the left and right legs are located on opposite sides of the rotation center of the rotating shaft 13.

The cylinder 10 and piston 11 constitute an operating body that reciprocates with air pressure applied from the bellows 3. Further, the pin 14 and the cam 16 constitute a converting member that converts reciprocating motion into rocking motion.

With the above configuration, when the handle 17 of the handcart A is pushed to make it run, the cam 6 rotates as the rear wheel 4 rotates.
Since the bellows 3 repeatedly presses and releases the pressure on the back surface of the bellows 3, the bellows 3 pressurizes and depressurizes the inside of the cylinder 10 via the connecting pipe 3a. This causes the piston 11 to reciprocate. and,
As a result of the reciprocating movement of the piston, the left and right cams 16 are alternately swung in opposite directions via the pins 14, so that the left and right legs 12 of the doll alternately repeat vertical movements.

In other words, as the wheelbarrow moves, the doll riding in the wheelbarrow flaps its legs, which are part of its body, up and down, expressing its joy.

In the above embodiment, the legs are moved up and down as part of the doll's body, but for example, the arms of the doll,
By arbitrarily selecting one or more of the neck, eyeballs, lips, etc., and using the same pneumatic drive means as above to move them as the handcart travels, you can enjoy expressions of facial expressions through the doll's body movements. I can do it.

Effects of this invention As described above, according to this invention, the space for installing the bellows is formed by the rear wall of the housing part of the handcart and the side wall extending rearward from the rear wall,
In addition, since the operating body is provided inside the body of the doll and the bellows and the operating body are connected through the rear wall of the storage section, neither the air pressure generating means nor the air pressure driving means are exposed to the outside, so Even when the doll moves while running, the principle behind it is not easily visible, so it is not exciting. Furthermore, since it is possible to prevent children and the like from directly touching the pneumatic drive means, there is no risk of failure or injury, and it is safe.
