Description

Swing {A swing}

The present invention relates to a swing, and more particularly, to a swing capable of reciprocating alone by a kinematic design without rolling a foot or pushing another person on the ground.

A swing is a ride that moves forward and backward in the state of sitting on the base with two bases at the bottom of the two rows, rolling with the feet or pushing by someone else.

Since these swings use ropes, safety problems arise, so they can be used as round rods.

However, the swing needs to find a way to ride on its own because a child who cannot stand and rolls or who lacks strength can move only when someone pushes or pushes on the ground.

In order to solve this problem, Patent No. 937440 (announced on January 22, 2010) filed by the present inventor has been disclosed. In the prior art, as shown in FIG. 1, a pair of frames 10 spaced apart from each other, a rotating shaft 20 freely rotated while being coupled to cross the upper portion of the frame 10, and the rotating shaft 20 Vertical rods 30 extending from both sides to the lower side, a chair 40 rotatably mounted on the lower end of the vertical rods 30, and extending further from the lower side of both sides of the chair 40 to the lower end portion The mounting plate 42 to which the vertical rod 30 is hinged 45 is formed to be spaced apart from each other to protrude outward from both sides of the chair 40, and restrains the vertical rod 30 of the chair 40. It was configured to include a rear stopper 50 and the front stopper 60 to define the front and rear turning angle.

Therefore, the rotational shaft is located at the bottom and the center of gravity is tilted upward, the chair 40 is to be able to move the swing actively as it flips back and forth.

However, the prior art as described above was produced by the present inventors and tested, and as a result, there is a problem in that the chair has to give a lot of power to return to the front again. In other words, the rotation axis of the chair is located at the bottom of the chair, so it is good to move the chair back and forth, but once it is crossed, it is difficult to come back.

In addition, in order to flip the chair, you need to hold something with your hand and give strength. However, if the chair is made wide, you can't hold the vertical rods on both sides by yourself, and even if the two people hold the vertical rods together and shake it, the swing doesn't fit and the swing doesn't move actively.

In addition, in order to get on the swing, you need to step on the footrest, and when you step on the footsteps, the chair is tilted forward and pushed back.

The present invention has been made to solve the above problems, by adding elasticity to the front and rear movement of the chair can double the restoring force of the rotation of the chair, to make the footrest of the chair folded to get on or off the chair It is to provide a swing that can be folded for the first time to facilitate the use.

The present invention to solve the above problems,

A pair of frames spaced apart from each other, a rotating shaft that is freely rotated while crossing the upper portion of the frame, a vertical rod extending downward from both sides of the rotating shaft, and the center of gravity at the bottom of the vertical rod is rotatably mounted upwards In the swing containing a chair,

Both sides of the chair are provided with a stopper that surrounds the longitudinal rods in a "c" shape with spaces left and right separated from each other, and a spring is connected from the center of the stopper to the upper side of the swing.

At this time, the spring is preferably vertically fixed to any one of the frame or the rotating shaft.

And the chair is coupled to the folding footrest, the front of the chair may further include a handle connected across the central portion of the vertical rods.

Here, the handle is hinged to one side of the vertical rod, the other side of the vertical rod is formed to latch the handle, the central portion of the handle can be folded by the joint.

As described above, the swing according to the present invention has the advantage of riding alone in a sitting position without anyone's help or rolling the foot on the ground, and enables the movement of the chair more actively by a spring and a handle, and a folding footrest. There is an advantage that can be prevented by accident by the handle which is overhanging.

6 is a perspective view showing a folded state of the handle.

Hereinafter, a swing according to a preferred embodiment of the present invention will be described with reference to the accompanying drawings.

2 and 3, the swing 100 according to the present invention is the frame 10, the rotation shaft 20, the vertical rod 30 and In addition, the chair 40 has a basic configuration and additionally includes a spring 110 and a handle 120.

The frame 10 is used as a means for supporting the swing 100 while the frame 10a on one side and the frame 10b on the other side are spaced apart from each other to determine the width of the swing 100. Each of these frames 10 has a "∩" shape to serve as four legs. One side crossbar 11a is formed at one side of the frame 10a on the inner upper side of the frame 10 formed as described above, and the other side crossbar 11b is formed at the other frame 10b.

The rotating shaft 20 is rotated by being coupled to the upper surface of the crossbar 11, the coupling plate (21a, 21b) is integrally formed so that the rotating shaft 20 is coupled to the central portion on the upper surface of the crossbar 11, the coupling plate Bearings may be embedded between the 21a and 21b and the rotating shaft 20 for smooth rotation of the rotating shaft 20.

The vertical rod 30 extends downward from a portion adjacent to both ends of the rotation shaft 20, and hangs the chair 40 at the lower end thereof. Here, the one side vertical rod 30a and the other side vertical rod 30b are integrated by being combined with the rotating shaft 20 by welding or the like, so that each vertical rod 30 is reciprocated together without shifting when the chair 40 moves back and forth. You can exercise. That is, since the vertical rods 30 are not integrally coupled to the rotation shaft 20, the vertical rods 30 are moved separately so that the reciprocating motion of the chair 40 is not smooth.

Chair 40 has a saddle, a back and a footrest 41 is formed so that a person can sit, the width of the chair is proportional to the separation distance of the vertical rod (30). Lower ends of the vertical rods 30 are coupled to the lower side of both sides of the chair 40, the hinge 43. The chair 40 thus coupled has a structure that can be easily flipped clockwise or counterclockwise by its own weight since its pivot center is located under the chair.

On the other hand, as described above, when the chair 40 is folded back and forth, the user cannot sit or ride on the chair, so the chair needs a stopper to suppress rotation. Therefore, the stopper 50 is formed to surround the vertical rods 30 in the form of the "c" in a state sandwiching the vertical rods 30 on both sides of the chair 40. At this time, the front and rear intervals of the stopper 50 should be sufficient to secure a sufficient free space because the front and rear pivot angle of the chair 40 is limited.

The spring 110 is a tension spring connected from the center of the stopper 50 to the upper side of the frame 10. The upper end of the spring 110 may be fixed on the frame 10, the crossbar 11 or the rotating shaft 20, and when the chair 40 is tilted forward or backward, the chair 40 is pulled back. The chair 40 makes it easy to return to the original position.

Handle 120 is in the form of a bar, is installed to cross in the transverse direction in front of the chair (40). The handle 120 is hinged to be rotatable to one side of the vertical rod 30, the other side of the vertical rod 30 is formed with a latch 31 so that the handle 120 can be covered. And the handle 120 is a joint 121 is formed in the center can be folded or folded after folding once.

The footrest 41 formed in the chair 40 according to the present invention can be folded using a folding mechanism such as a hinge at the contact portion with the saddle, so that the footrest when climbing on or off the chair 40 ( 41) can be folded first and then used to prevent shaking of the chair caused by stepping on the footrest 41.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the invention as defined by the appended claims. .
