Description

Automatic closing structure of door using slope {AUTOMATIC CLOSING STRUCTURE OF THE DOOR USING A SLOPE}

The present invention relates to an automatic closing structure of a door using an inclination. More specifically, when an incline is formed on the rail of a sliding door frame and the door is pushed in a direction with a high inclination, the roller provided at the bottom of the door moves in the direction with a low inclination by gravity. It relates to an automatic closing structure of a door using an inclination that rotates and moves the door to its original position.

Generally, sliding doors are often installed between the living room and the front room of a classroom, office, or apartment, and are largely divided into manual, semi-automatic, and automatic types.

A manual sliding door is one in which the door is opened or closed by pushing it solely with human force, while an automatic door is one in which the door is opened or closed by a driving means such as a motor.

Meanwhile, a semi-automatic door means that when the force to open the door is removed, the door closes in all sections.

At this time, the semi-automatic door is equipped with a pulling means that provides closing force and a stopper means that maintains the fully open state.

That is, when the external force is removed while the door is partially open, the door is automatically moved in the closing direction by the pulling means, and when the door is fully opened, the door is stopped by the stopper means and maintained in the open state.

At this time, if the fully opened door is slightly pushed in the closing direction, the door separated from the stopper means can be automatically closed.

In the semi-automatic sliding door, which is a conventional technology registered in Korea Patent No. 10-1792618 (registered on November 26, 2017), a pair of rails provided in the moving space formed inside the rail frame installed at the top of the opening of the building is attached to the top of the door. The connected roller is provided to move back and forth by sliding, and the closing part including the elastic module allows the door to move in the closing direction.

In such a semi-automatic sliding door of the prior art, when the sliding door is opened, the door can stop in an open state at a position desired by the user, and when the sliding door is closed, the door is automatically closed after a certain length of closing operation. .

However, conventional semi-automatic sliding doors are usually opened and closed with the upper part of the sliding door suspended from the rail frame at the top of the door frame. Therefore, in order to support the entire load of the door by the rail frame, the configuration of the rail frame must be relatively high. There is a problem that it must be enlarged, and in particular, since the door is supported only at the top, there is a problem that flow occurs toward the front and rear sides.

Republic of Korea Patent No. 10-1792618 (registered on November 26, 2017)

In order to solve the problems of the prior art as described above, the present invention forms an incline on the rail of the sliding door frame, and when the door is pushed in a direction with a high inclination, the roller provided at the bottom of the door rotates in the direction of a low inclination by gravity to open the door. It provides an automatic closing structure for the door using an inclination that moves the door to its original position.

In addition, an inclined portion is formed on the fixing piece of the hinge provided in the door frame of the swing door, and a rotary bearing is provided on the inclined portion, so that when the swing door is opened, the rotary bearing moved to a high position in the inclined portion moves to a low position due to the center. This provides an automatic door closing structure using an inclination that rotates the hinged door to its original position.

The present invention is intended to solve the above problems.

An inclined portion consisting of an inner inclined rail forming an incline that increases from one side of the inner rail of the sliding door frame to the other side, and an outer inclined rail that forms an incline that increases from the other side of the outer rail of the sliding door frame to one side; and

Comprising a roller portion formed on the lower part of the door sliding along the inclined portion.

It provides an automatic closing structure for the door using inclination.

In the automatic closing structure of a door using an inclination according to an embodiment of the present invention, the roller unit includes a first roller formed on the other side in the longitudinal direction of the inner door located on the inner inclined rail; a second roller located spaced apart from the first roller and having a smaller diameter than the first roller so that the inner door is horizontal; a third roller formed on one side in the longitudinal direction of the outer door located on the outer inclined rail; And it may further include a fourth roller located spaced apart from the third roller and having a smaller diameter than the third roller so that the outer door is horizontal.

In the automatic closing structure of the door using an inclination according to an embodiment of the present invention, when the roller unit opens the inner door by sliding it from one side to the other, the inner door is located at a high slope of the inner inclined rail, and is moved by gravity. The first roller and the second roller may rotate toward a low inclination to move the inner door to its original position.

The automatic closing structure of a door using an inclination according to an embodiment of the present invention,

An upper fixing piece on one side of which is coupled to the hinged door and a lower fixing piece on the other side of which is coupled to the door frame are connected by a pivoting axis, and a hinge part is spaced between the upper fixing piece and the lower fixing piece to form a ramp; and

A shaft portion connected to a lower portion of the upper fixing piece and a rotary bearing rotatably coupled to the shaft portion may include a roller portion that moves along the ramp by rotation of the shaft of the upper fixing piece.

In the automatic closing structure of a door using an inclination according to an embodiment of the present invention, when the roller unit rotates and opens the hinged door, the rotation bearing is located at a high inclination along the ramp and rotates toward a low inclination by gravity. This may be characterized in that the swing door is rotated to its original position.

The automatic closing structure of the door using an inclination according to the present invention forms an incline on the rail of the sliding door frame, and when the door is pushed in a direction with a high inclination, the roller provided at the bottom of the door rotates in the direction of a low inclination to return the door to its original position. By moving it, there is an advantage that the door can be conveniently closed without having to lift a heavy load and close the door.

In addition, there is an advantage in that the sliding door can be leveled by varying the diameters of the rollers located at a low slope and the rollers located at a high slope.

In addition, there is an advantage in that the central portion of the inner inclined rail and the central portion of the outer inclined rail are formed at the same height, so that when the inner door and the outer door are closed, the rotation of the roller portion is restricted and each door can be maintained in a closed state.

In addition, the automatic closing structure of the door using an inclination according to the present invention forms an inclined portion on the fixing piece of the hinge provided in the door frame of the swing door, and has a bearing on the inclined portion, so that when the swing door is opened, the inclined portion moves to a higher position. There is an advantage in that the door can be automatically closed by moving the bearing to a lower position and rotating the hinged door to its original position.

The second roller 220 is located away from the first roller 210, has a smaller diameter than the first roller 210, and serves to keep the inner door 12 horizontal.

That is, the second roller 220 is located at a portion with a higher inclination than the first roller 210 at a low inclination position, and is formed with a smaller diameter than the diameter of the first roller 210 to accommodate different height differences. . Due to this, the inner door 12 is leveled.

The third roller 230 is formed on one side in the longitudinal direction of the outer door 13 located on the outer inclined rail 120.

The fourth roller 240 is located away from the third roller 230, has a smaller diameter than the third roller 230, and serves to keep the outer door 13 horizontal.

Here, since the fourth roller 240 has the same role as the above-described second roller 220, please refer to the detailed description of the second roller 220.

In this way, when the roller unit 200 opens the inner door 12 by sliding it from one side to the other, the inner door 12 is located at a high slope of the inner inclined rail 110, and the first roller 210 is moved by gravity. ) and the second roller 220 rotates toward a low inclination to move the inner door 12 to its original position.

Therefore, the inner door 12 can be automatically closed by moving it in a direction with a lower inclination without a separate operation to open and then close the inner door 12.

In addition, the outer door 13 can also be opened and closed in the same way as the inner door 12.

As shown in Figure 4, the automatic closing structure of the door using an inclination according to the second embodiment of the present invention 20 has an upper fixing piece 310 on one side coupled to the hinged door 14 and the other side coupled to the door frame. The lower fixing piece 320 is connected to the rotating shaft 330, the inclined portion 300 is spaced between the upper and lower fixing pieces to form a ramp 340, and the shaft portion 410 is connected to the lower part of the upper fixing piece. ) and a rotation bearing 320 rotatably coupled to the shaft portion includes a roller portion 400 that moves along the ramp by shaft rotation of the upper fixing piece.

Referring to FIG. 4 , the hinge portion 300 further includes an upper fixing piece 310, a lower fixing piece 320, a pivot axis 330, and a ramp 340.

One side of the upper fixing piece 310 is coupled to the upper and lower portions of the hinged door 14 along its longitudinal direction.

The other side of the lower fixing piece 320 is coupled to the door frame 11 and is located below the upper fixing piece 310.

The rotation axis 330 has a cylindrical shape and is formed with a diameter wider than the axis of a generally known hinge. This is to provide a distance at which the roller unit 400, which will be described later, can move along the outer peripheral surface.

The ramp 340 forms a slope at the lower part of the upper fixing piece 310 and the upper part of the lower fixing piece 320, and is spaced apart from each other while facing each slope so that the rotary bearing 420 can be positioned. In addition, the rotary bearing 420 is allowed to move along an incline in response to the rotation of the upper fixing piece 310 about the rotation axis 330.

Referring to Figures 4 and 5, the roller unit 400 moves along the ramp 340 in response to the axial rotation of the upper fixing piece 310.

When the roller unit 400 rotates and opens the hinged door 14, the rotation bearing 420 is located at a high slope along the ramp 340, and rotates toward a low slope due to gravity to open the hinged door 14. It serves to rotate the device to its original position.
