The stroller capable of pushing a door according to a preferred embodiment of the present invention is composed of a general stroller consisting of a frame 10, a seat 20, a wheel 30 and a push bar 40 as shown in FIG. 1, Each configuration has technical characteristics.

Before looking at the technical characteristics of each configuration, let's look at the configuration of a general stroller.

The frame 10, by serving as an overall structural support of the stroller, may be used as a handle, wheelbase, seat base, etc. according to its position and role.

The frame 10 may be configured in various forms. Largely, the rear vertical frame 11 formed downward from the handle gripped by the user, the parent, the horizontal frame 13, one side of which is horizontally formed on the side of the vertical frame, and the front vertical frame downwardly formed from the other side of the horizontal frame 13 ( 15) can be distinguished.

The seat 20 is generally configured in a form with a backrest, and is mounted on the above-described horizontal frame 13 , and the backrest may be of a type coupled to the rear vertical frame 11 .

The seat 20 may be made of a resilient material for the convenience of the occupant, or may be provided with specifications such as a seat belt that can prevent the occupant from leaving.

In general, a plurality of wheels 30 may be provided according to the shape of the frame 10 , and a braking device capable of fixing the wheel 30 may be provided to prevent unexpected movement when the stroller is stopped.

The push bar 40 is installed on the front vertical frame 15 located in front of the seat 20 and may be detachable.

The push bar 40 may serve to open the double door by contacting the outside, for example, the double door and transmitting the force applied to the front by the user through the handle.

Since the push bar 40 is installed in front of the seat 20, it can be used as a support for installing a tarpaulin or a sun visor using the handle and the push bar 40 as a contact point.

A detailed look at the push bar 40 having technical characteristics distinguished from each of the above-described general components.

The push bar 40 may include a body part 100 , a coupling part 200 , a buffer part 300 , and a folding part 400 .

First, look at the body part 100 .

The body portion 100 occupies the largest portion of the configuration of the push bar 40 , and may indicate the overall shape of the push bar 40 .

The body part 100 may be configured in various shapes, but it may be preferable in terms of strength or ease of manufacture to be configured in an arch shape when viewed from the top.

In addition, the arcuate structure of the body portion 100 may serve to effectively distribute the impact when the push bar 40 comes into contact with the outside to minimize the transmission of the impact force to the occupant.

The body part 100 may be provided in a form in which the vertex side is inclined upward, and in detail, it is formed so as to be horizontal from the coupling part 200 to be described later to the vertex side, and is inclined upward from a predetermined position to the vertex. can be configured.

The body portion 100 has a strength enough to transmit a force by being in contact with the outside when pressed, and is formed of a flexible material having elasticity, so that it can be coupled even when the width of the front vertical frame 15 is various. .

A photovoltaic panel is installed on the upper surface of the body part 100, and it may be possible to generate electric power using this to charge a battery to be described later.

A plurality of rotating bodies 110 may be additionally provided in the body portion 100 .

The plurality of rotating bodies 110 have a groove in which the shaft is interpolated into the body part 100, and the rotating body 110 penetrated to the shaft is attached, or the body part 100 itself can seat the rotating body 110 on its own. It may also be possible to provide the rotating body 110 in the form of a bearing to rotate.

The rotating body 110 is installed to protrude from the outer surface of the body part 100 so that the push bar 40 contacts the outside before the body part 100, so that the push bar 40 is moved to the outside. It is possible to make the stroller smoothly proceed by the rotation of the rotating body 110 at the time of contact.

Additionally, when the rotation body 110 and the body part 100 are installed, it may be possible to use a separate elastic body so that the rotation body 110 first absorbs the shock when the push bar 40 comes into contact with the outside.

Next, look at the coupling part 200 .

The coupling part 200 is installed at both ends of the arcuate body part 100 and is coupled to the front vertical frame 15 to serve to fix the push bar 40 .

The shape of the coupling part 200 may be formed according to the shape of the front vertical frame 15 , and any shape may be possible as long as it can be detached from the front vertical frame 15 while maintaining its fixed state.

Preferably, it is coupled to the front vertical frame 15 in a tongs type for easy detachment, and it may be possible to fix the coupling part 200 using a fastening device that can be tightened.

In addition, the coupling part 200 is formed of a flexible material, for example, a synthetic resin material, so as to be fitted to the front vertical frame 15, so that the front vertical frame 15 can be fixedly coupled even when the size of the front vertical frame 15 is various.

The folding part 400 may be installed between the body part 100 and the buffer part 300, or it may be installed between the buffer part 300 and the coupling part 200, and the user adjusts the installation position arbitrarily. may also be possible.

For example, male threads are formed at both ends of the body part 100, and the folding part 400 or the buffer part 300 is provided with a female thread and a male thread, respectively, so that the user determines each installation location and screws accordingly. It may also be possible to install easily by coupling.

The folding part 400 may be shaft-coupled so that one side and the other side are rotatable based on the central axis, or it may be shaft-coupled so that only one side is rotatable.

The foldable portion 400 may be configured in such a way that the user sets and fixes the rotation angle, so that the angle between the push bar 40 and the horizontal plane is varied.

Additionally, the stroller may further include a battery (not shown).

The battery is configured in a form that can be charged, it may be preferable to be located at the bottom of the seat 20 of the stroller for structural stability.

The battery may be charged due to the inlet of electric force from the outside, or it may be possible to charge electric power through driving of a stroller or using a solar panel provided in the push bar 40 .

In detail, the stroller must be run outdoors for that purpose, and it may be possible to charge the battery by converting the rotational force generated on the wheel 30 or sunlight applied to the stroller by running into electric power.

A detailed method of converting rotational force or sunlight into electric power is a known technique and detailed description thereof will be omitted.

The electric power stored in the battery is used for rotation of the wheel 30 when the stroller goes uphill and can be used in various ways, such as to facilitate driving or to install a terminal for charging the user's portable device. When the push bar 40 is folded, it may be possible to rotate it electrically using the electric power of the battery.

The user can adjust the angle formed by the push bar 40 with the horizontal plane by electrically rotating the folding part 400 up to a desired rotation angle and then fixing it.

Additionally, a detachable support (not shown) may be provided between the push bar 40 and the seat 20 .

The push bar 40 serves to contact the outside, and may be in a form that protrudes forward of the stroller rather than the seat 20 . Generally, the lower body of the occupant, more precisely, the leg of the occupant, is exposed in front of the seat 20 . may have been

The support is installed between the push bar 40 and the lower surface of the seat 20 so that the lower body of the occupant is seated, thereby providing a comfortable ride for occupants and removing the risk of collision due to exposure.
