First, the foldable main body frame 100 according to the present invention will be described.

The foldable main body frame 100 is formed in a rectangular parallelepiped shape so as to support the entire body of the baby wagon 1 and to change its shape by folding or spreading the center portion with respect to the longitudinal direction.

As shown in FIG. 4, the main frame 110, the supporting frame 120, the side frame 130, the front handle frame 140, and the rear handle frame 150 are formed.

First, the main frame 110 according to the present invention will be described.

The main frame 110 is a frame shaped like a rectangle erected upright symmetrically to the front and rear ends of the main frame 110. The main frame 110 is supported at its lower end by a supporting frame coupled thereto, And is composed of a front main frame 110a and a rear main frame 110b so as to be coupled and supported.

The front main frame 110a is a frame positioned in the front direction of the two main frames. The front main frame 110a is coupled to the top center front direction of the front main frame and includes a detachable detachable portion 110a -1), and a rotary shaft portion 110a-2, which is coupled to one side of the lower center of the front main frame and supports the lower end of the front handle handle frame in an axial shape, is formed.

Here, the notch portion 110a-1 serves to support one side of the length adjusting frame 143c formed on the left and right sides of the center support frame 142 in both lateral directions.

This is used to move the baby wagon through the rear handle frame or to secure the front handle handle frame 140 to minimize volume during storage.

8, the handle rotatable shaft coupling part 141 is rotated with respect to the rotary shaft part when the protector pulls the baby wagon from the front and the front handle handle frame 140 is rotated, So as to rotate in a vertical direction.

Accordingly, it is possible to set a height at which the driver can comfortably operate according to the height of the protector, to allow the handle to be rotated in accordance with the terrain of the walker or the inclined surface of the protector, and to maintain a sufficient distance between the protector and the child wagon, It is possible to prevent the protector's foot from hitting the infant wagon, thereby making it easier for the protector in walking and preventing the ride comfort of the infant from falling.

The rear main frame 110b is a rear side frame of the two main frames. The side frames 110b-1 are formed on one side of the left and right sides of the main frame 110b to be engaged with the side frames 130, And a rear handle fixing frame 110b-2, which is formed at the upper and lower ends of the left and right sides, respectively, and is connected to the rear handle frame 150, is formed.

Here, the side supporting frame 110b-1 is a rod-shaped frame formed such that the rear end thereof is axially coupled and rotatable forward, and the front side of the side supporting frame 110b-1 is disengaged from one side of the side frame. The left and right sides of the rear main frame 110b are coupled to each other so that the baby wagons are folded and unintentionally collapsed in the unfolded state. It helps prevent accidents.

The rear handle fixing frame 110b-2 is a rod-shaped frame protruding rearward. The rear handle fixing frame 110b-2 is a bar-shaped frame formed by rearwardly engaging the left and right sides of the rear main frame 110b and the rear handle frame 150, So that it is possible to easily control the movement of the rear handle frame even if it is moved by the guardian alone by minimizing the loss of force when the user moves or changes direction by the force of pushing or pulling the rear handle frame And unnecessary waste of physical energy can be reduced.

As shown in FIG. 3, the main frame 110 according to the present invention includes an upper support fixture 111, a lower support fixture 112, and a canopy fixation pole 113.

The upper support fixture 111 is fixed to the upper left and right ends of the main frame formed in the forward and backward directions in an upright ' 111a are formed to support the upper left and right ends of the main frame.

The upper support fixture 111 penetrates the lower end of the pole insertion fixing hole 111a so that the canopy fixing pole 113 can be inserted into the main frame 110, A pole protrusion fixing screw 113a formed at the upper end of the canopy fixing pole 113 and a pole inserting fixing screw 113b formed at the lower end.

When the canopy 400 is installed, the pole insertion fixing hole 111a is fixed to the upper end of the main frame by fixing the pole protrusion fixing screw 113b located at the lower end of the canopy fixing pole, and when the canopy 400 is detached, The pole inserting set screw 113a located at the upper end of the stationary pole is fixed so that the canopy fixed pole is inserted and fixed in the main frame.

Accordingly, the canopy fixing pole 113 can not be fixed when the child wagon is folded and stored, so that it is possible to prevent the damage of the frame and the risk of injury of the user through the separation or loss.

The lower support fixture 112 is fixedly coupled to the left and right ends of the lower end of the main frame in the forward and backward directions and is engaged with the lower end of the side frame 130 to facilitate rotation.

In addition, the inner rear wheel support frame is coupled to the lower end of the left and right lower end support fixtures formed at the rear to support the rear wheel.

The canopy fixing pole 113 is inserted into the upper end of the main frame 110 in the form of a round bar having the same shape of a thread at the upper end and the lower end, A pole projection fixing thread 113b formed at the lower end of the threaded hole of the fixing hole 111a and a pole insertion fixing thread 113a formed at the upper end are selectively fixed.

This is because when the canopy is installed, the pole protrusion fixing screw 113b at the lower end is fixed to the pole inserting hole 111a at the upper inner surface of the upper support fixture 111, and in the canopy separation and folding mode, The fixing screw 113a is fixed to the pole inserting hole 111a on the upper inner surface of the upper support fixture 111. [

The canopy fixing pole 113 can be stably fixed in the canopy separation mode and the folding mode in which the canopy fixing pole 113 is inserted into the upright direction of the canopy as well as the upper direction of the main frame 110, Prevents the damage such as warp caused by protruding canopy fixed pole, user's safety accident, and prevents it from being lost and lost.

Second, the support frame 120 according to the present invention will be described.

The support frame 120 is a rectangular frame coupled to one side of the lower end of the reference frame and has a central axis at the center with respect to the forward and backward directions and is symmetrically folded or unfolded according to the rising and falling of the central axis, .

In the use mode of the baby wagon, the front and rear frames are formed horizontally with respect to the central axis to form a space in which the seat portion 400 can be opened. In the folding mode, It is folded in a symmetrical shape of 'V' shape and reduces the volume.

Third, the side frame 130 according to the present invention will be described.

The side frame 130 is supported by two pairs of 'X' shaped intersecting frames symmetrically formed on the left and right sides of the main frame.

In this case, the two pairs of 'X' shaped cross-shaped frames formed symmetrically are equally spaced and have the same angle, and the angle of rotation is equally variable when the rotation pin is inserted around the center pin.

When the central axis of the supporting frame 120 is raised, the wings are rotated by the rotation pin, the angle is reduced, the distance between the front and rear directions is reduced, the child wagon is folded, The gap between the front and rear directions is widened and the baby wagon unfolds.

Fourth, the front handle handle frame 140 according to the present invention will be described.

The front handle handle frame 140 has a lower end at the center of the lower end of the front main frame and is coupled to a detachable portion formed at the upper center of the front main frame and has an upper end formed with an inverted triangular shape So that the protector can drive the baby wagon in the forward direction.

It is composed of a handle rotation shaft coupling portion 141, a center support frame 142, and a length adjustment knob frame portion 143.

The handle rotation shaft coupling portion 141 is axially coupled to a rotation shaft portion formed at the lower center of the front main frame to rotate the front handle handle frame in the vertical direction.

The center support frame 142 is a columnar frame that is coupled upright to the upper end of the handle rotation shaft coupling portion, and a lever support portion is formed on one side of the upper end to support the front handle handle frame. Similarly, a lever support portion 142a is formed at the upper end thereof.

The lever support portion 142a is formed with a lever support portion 142a formed with a hole through which the length adjustment frame 143c passes, and rotates the fixing lever 142a-1 in the left and right directions, And serves to move and fix the length-adjusting frame 143c coupled to the right side in the vertical direction.

At this time, when the fixed lever 142a-1 is rotated to the left, which is the opened state, the frictional force acting on the length adjusting frame 143c is removed and the movable member can be moved in the vertical direction. (143c) is firmly fixed and blocks the movement in the vertical direction.

The length adjusting knob frame part 143 is coupled to the center support frame 142 and is moved and fixed in the vertical direction and serves to vary the length of the front knob handle frame.

Specifically, the length-regulating knob frame 143 has a handle frame lower end supporting portion 143a which supports the lower end of the length-adjusting frame symmetrically to the left and right sides and into which a central supporting frame is inserted.

A handle frame upper end supporting part 143b supporting the upper end of the length adjusting frame symmetrically to the left and right sides and having a center supporting frame inserted into a hole formed at the center thereof;

A length-regulating frame 143c of a circular rod shape which is connected to the left and right sides of the central support frame in parallel and separated from each other;

And a reverse osmosis knob frame 143d connected to the length adjusting frame and penetrating the upper end of the handle frame upper support portion and symmetrically joined to the left and right sides to have an inverted triangular shape.

Accordingly, the length of the front handle handle frame 140 can be varied according to the difference in the elongation of the protector and the inclined terrain, so that the protector can be set and fixed at a height that facilitates the driving operation. It is possible to secure the separation distance, prevent the protector's heel from colliding with the body of the wagon, allowing comfortable walking, and transmitting the pulling force to the lower part of the child wagon, thereby minimizing the shaking and enabling stable movement.

Further, even if the stride and step of the pedestrian are not constant, the front handle handle frame 140 is rotated in the vertical direction to prevent the front of the infant wagon from momentarily being lifted and landed, To prevent falling.

Fifth, the rear handle frame 150 according to the present invention will be described.

The rear handle frame 150 is mounted on the rear left and right sides of the main frame and coupled to the rear main frame 110b through a rear handle fixing frame 110b-2, And a control button 151 is coupled to control a step angle of the rear angle adjusting handle 152.

In this case, the rear angle adjusting handle 152 can be adjusted in a stepwise manner by a button adjustable rotation, and the handle angle can be set according to the user's selection while pressing the left and right rear handle rotation buttons.

At this time, the rear handle is horizontally aligned with the rear support frame and can be rotated in ten steps from 0 ° in the folded state to 180 ° in the upright direction in the opposite direction.

It rotates at an angle of 18 ° when it rotates in one step, and it can minimize the force acting on the arm by varying the angle according to the user's height, arm height, uphill and downhill, dragging or pushing forward In folding mode, the rear handle and rear support frame are leveled to minimize volume.

In addition, when the rear handle frame is pushed and moved, when the angle of the rear handle is set to be vertical, the gap between the protector's foot and the infant wagon is maximized to prevent a kickback phenomenon in which the forward foot hits the infant wagon, Comfortable walking is possible, and the ride comfort of the infant also increases.

Next, the wheel part 200 according to the present invention will be described.

The wheel part 200 is fastened to the lower end of the foldable main frame in the front-rear direction to move the baby wagon.

As shown in FIG. 3, this includes the front wheel drive unit 210 and the rear wheel drive unit 220.

First, the front wheel drive unit 210 according to the present invention will be described.

The front wheel drive unit 210 is coupled to the left and right ends of the lower main frame, and is rotatable 360 degrees in the horizontal direction.

In this case, the front wheel drive wheels are not fixed in a fixed direction but are rotated 360 degrees in the horizontal direction to induce a smooth direction change, and reduce the force required to change the direction, thereby reducing the fatigue of the protector.

Second, the rear-wheel drive unit 220 according to the present invention will be described.

The rear wheel drive unit 220 is coupled to the left and right ends of the lower end of the rear main frame 110b and is connected to the left and right ends of the center shaft 223 passing through one side of the side center of the rear wheel fixed frame, A rotary shaft 221a having a projection 221a-1 formed on one side of the rear end of the rear wheel fixing frame 221 is coupled and a rotary shaft 224 connecting the left and right rotary blades is formed, Shaped pedal brakes 225 are coupled to the center of the shaft 223 and the rotary shaft 224. The '

The 'b' shaped pedal brake 225 controls the rear wheel to stop the rotation of the rear wheel drive wheels by stepping the rear face downward when pushing or pulling the child wagon from the rear.

At this time, if the rear surface of the 'b' shaped pedal brake 225 is stepped downward, the rotary shaft 224 rotates in the lower direction with respect to the center shaft 223, and the left and right rotary blades are rotated, The rotation of the rear wheel drive wheel is stopped, and when the front wheel is stepped in the bottom direction, the projection inserted into the toothed wheel is released and the rear wheel drive wheel can be rotated.

10, since the rotation of the rear wheel drive wheels is completely blocked by the projections 221a-1 inserted into the teeth 222a, there is no slippage, and there is no possibility that the brakes are released naturally, Can be stably stopped.

Next, the seat portion 300 according to the present invention will be described.

The seat portion 300 is fixedly coupled to the inner periphery and the lower end of the foldable main body frame in a rectangular basket shape by a snap button, a buckle, and a Velcro, thereby providing a space in which the infant can comfortably rest in the infant wagon .

Here, the thickness of the seat portion is 5 mm to 10 mm, and a folding crest is formed at a folded portion of the foldable main frame in accordance with the folding mode so that folding is performed, and a folding ring is formed in the center of the inner surface of the seat portion.

When the thickness of the seat portion is less than 5 mm, the seat portion is difficult to perform the cushioning function properly. Therefore, the shake and impact are directly transmitted to the infant during the movement. If the thickness is 10 mm or more, the folding body frame is not smoothly folded, A problem arises.

A five-point safety belt is formed so as to face the inside and outside of the seat according to the present invention so that both shoulders, waist and both thighs of the infant are not shaken.

The 5-point combination seat belt covers all the upper body, allowing infants and children of various ages from infants to children who have difficulty keeping up.

Further, the seat portion according to the present invention is formed with a one-touch folding ring at the center of the inner bottom surface.

This pulls the one-touch folding ring to narrow the distance between the front main frame and the back main frame coupled with the seat portion, folding the side frame and the support frame so that the baby wagon is folded.
