The present invention relates to a chair having an inclination adjusting device, and in particular, an inclination adjusting device characterized in that the closure plug applied to the lower end of the chair is configured to be inclined to adjust the inclination so that the ground can be stably landed. It relates to a chair having a.

In general, the chair is being developed to support the buttocks or waist of the human body, and there is a chair type consisting of a hip support and a leg to support only the buttocks, and to support the waist further. There are chairs equipped with a waist support at the same time.

In addition, the legs of the chair is made of a variety of materials, such as wood or synthetic resin materials, and in particular, chairs with legs installed in steel, such as meeting rooms and lounges are used a lot.

And, the reason for using a lot of the legs of the steel is because it is easy to bend to be easy to bend because it is easy to bend, and because the weight is light and easy to move is used in a simple meeting room or a break room.

1 illustrates a chair having a conventional iron leg, and as shown in the drawing, the back support 10, the hip support part 20, and the leg part 30 are formed, and the end of the iron leg 30 is narrow. It maintains the form of the picture.

Accordingly, the end of the leg 30 was casing with a stopper 40, but since it is still inclined relative to the floor surface, pressure is concentrated on a part of the floor surface, resulting in scratches on the floor surface, and the chair is misplaced backwards. There is a problem that can fall.

That is, a chair made of steel pipes with legs 30 produces a chair leg by processing steel pipes, so that a slope with the bottom surface occurs during folding of the steel pipes. It was very difficult to have a leg lower surface in close contact with the bottom surface.

As a result, the chair having a conventional iron leg is not in close contact with the floor surface, so the pressure is concentrated on a part of the floor surface, so that the floor surface is scratched and a stable landing is difficult.

Of course, if the plastic legs are also in the form of pipes are often installed inclined with the bottom surface often show the same problems as the steel pipe legs.

The present invention is to solve the above problems,

The purpose of this is to install an auxiliary mechanism free of angle control of the inclined surface so that the steel chair and the floor can be completely in contact with each other.

As a means for achieving the above object,

The present invention includes a support in a pipe which is formed in the outer periphery of a plurality of rings in the cylindrical body inserted into the lower portion of the pipe-type chair legs;

A ball joint comprising a vertical bar inserted into the support in the pipe and a spherical ball formed under the vertical bar;

Conical shape is formed by forming a circular space, the ball of the ball joint is inserted through the upper surface is characterized in that the ball consists of a floor support that is configured to be freely rotatable in the circular space.

Other objects, specific advantages and novel features of the present invention will become more apparent from the following detailed description and the preferred embodiments associated with the accompanying drawings.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. First of all, in adding reference numerals to the components of each drawing, it should be noted that the same reference numerals are used as much as possible even if displayed on different drawings. In addition, in the following description of the present invention, if it is determined that the detailed description of the related known function or configuration may unnecessarily obscure the subject matter of the present invention, the detailed description thereof will be omitted.

Figure 3 is a chair tilt adjustment operation state of the present invention.

4 is an application state diagram of the present invention,

As shown, the inclination adjustment mechanism of the present invention is a structure that is coupled to the lower portion of the leg 30 is composed of a support 110 in the pipe, the ball joint 120 and the bottom support 130.

The pipe support 110 has a plurality of ring 111 is formed on the outer periphery is inserted into the lower portion of the chair leg (30).

In addition, the ball joint 120 is composed of a vertical bar 121 inserted into the support in the pipe, and a spherical ball 122 inserted into the bottom support 130.

The bottom support 120 is formed by forming a circular space having a substantially conical shape, and the ball 122 of the ball joint 120 is inserted through the upper surface so that the ball 122 can freely rotate in the circular space. It is composed.

The present invention constituted as described above manufactures the support 110 in the pipe, the ball joint 120 and the bottom support 130, respectively.

Of course, when making the mold frame made in the pipe support 110 is manufactured in a cylindrical shape as a whole, but inserts a plurality of ring 111 structure on the outer periphery is configured to fit tightly to the chair leg, in the embodiment of the present invention 3 The number of rings 111 is illustrated, but the number is at least one, and most preferably about three are most suitable when considering the convenience of production.

And, since the ball joint 120 is coupled between the pipe support 110 and the bottom support 130, it is preferable to manufacture the steel to maintain the coupling strength, the vertical bar 121 portion of the pipe support It is manufactured by inserting in the spherical ball 122 is inserted into the floor support 130 is configured.

The bottom support 130 is built in the ball portion as a whole cone shape, but the ball is made to be freely rotatable in the space 131, so that the vertical bar portion of the ball joint 120 can be moved within various angles.

For reference, when the ball 122 and the bottom support 130 are coupled, the bottom support 130 is just ejected and the ball 122 is forcedly inserted using a mechanism such as a hammer when heat remains.

The reason why the ball 122 and the bottom support 130 are coupled when the heat remains is because the bottom support 130 is broken when the ball 122 is inserted in the state where the heat of the bottom support 130 is cooled, When heat remains on the bottom support 130, the ball 122 is easily stretched into the space 131 of the bottom support 130 due to elasticity.

When the configuration of the inclination adjusting device 100 is completed as described above, since the vertical bar 121 of the ball joint 120 is coupled to the support 110 in the pipe, the support 110 in the pipe 110 and the bottom support 130 are provided. This will achieve a variety of inclination angle and thus to support the bottom surface stably after coupling the support 110 in the pipe to the leg 30 of the chair.

That is, the bottom support 130 and the pipe support 110 form a proper inclination angle according to the bending angle of the leg 30 so that the bottom support 130 always forms a horizontal plane so as to be in close contact with the bottom surface. 110 is fixed to the chair leg at the angle of the leg 30 of the chair by the action of the ball joint 120.

Therefore, when the inclination adjustment device 100 of the present invention is inserted into the pipe-type chair legs having various angles, the lower part of the chair is securely supported closely to the floor surface to prevent the pressure from being distributed to the floor surface. In addition, even if the user puts the chair back, the inclination adjuster keeps the bottom support shape while changing the angle, thereby preventing the case of falling backward.

The reason why the angle can be maintained even if the user is put back as described above is because the ball can freely rotate in the space of the bottom support.

As described above, the present invention is configured by combining the inclination adjustment mechanism capable of free inclination adjustment to the lower part of the chair leg, thereby stably supported on the floor surface to provide an effect of preventing scratches on the floor surface, and The free tilt angle can be maintained to prevent the user from falling back even if the user leans back the chair.

Although the present invention has been described in connection with the above-mentioned preferred embodiments, various other modifications and variations may be made without departing from the spirit and scope of the present invention. Accordingly, it is intended that the appended claims cover such modifications and variations as fall within the true scope of the present invention.
