Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

2 to 6 illustrate a sliding door according to the present invention. The sliding door is composed of upper and lower guide rails 10 and 20 extending in the front-rear direction on the upper and lower sides of the doorway 2 formed on the wall surface 1, And the door panel 30 slidably coupled to the upper and lower guide rails 10 and 20, respectively.

At this time, an upper roller 40 coupled to the upper guide rail 10 and a lower roller 50 slidably coupled to the lower guide rail 20 are provided at upper and lower ends of the door panel 30, So that the door panel 30 can be pushed forward to open the door 2.

According to the present invention, a guide bar (60) is provided below the lower guide rail (20).

The guide bar 60 is formed in the shape of a straight bar made of steel, which is a magnetic material, and is embedded in the bottom surface 3 to be positioned below the guide rail.

Preferably, the guide bar 60 is completely embedded on the bottom surface 3 so that the top surface is not visible, as shown in Fig.

The lower guide rail 20 is composed of a plurality of support blocks 21 rotatably coupled to each other by a hinge shaft 22 extending in the lateral direction, As shown in Fig.

In detail, the support block 21 is formed in the shape of a metal block extending in the front-rear direction, and the upper and lower surfaces are in the form of a flat surface. The front end of the support block 21 is formed with an engagement groove 21a and the rear end thereof is provided with an extension portion 21b And is coupled with the hinge shaft 22 passing through the coupling groove 21a and the extending portion 21b so as not to move in the lateral direction but to rotate only in the vertical direction.

At this time, protrusions 21c projecting laterally are formed on both sides of the support block 21 in the longitudinal direction.

The support block 21 is provided with a magnet member 24.

The magnet member 24 is made of a general permanent magnet and has a lower surface exposed to the lower side of the support block 21. When the support block 21 is placed on the bottom surface 3, The support block 21 is fixed to the upper side of the guide bar 60 in a straight line.

That is, when the support block 21 is placed on the bottom surface 3 so as to be positioned above the guide bar 60, the support block 21 is moved by the magnetic force of the magnet member 24, The guide bar 60 is formed in the form of a straight bar so that the support block 21 located at the upper portion of the guide bar 60 is also prevented from being detached from the guide bar 60, As shown in FIG.

The door panel 30 is formed with a receiving portion 31 in which the rear end of the lower guide rail 20 is received.

The receiving portion 31 is formed to extend upward from the lower end of the door panel 30 to the inside of the door panel 30 so that the door panel 30 can be extended in the lateral direction The rear end of the lower guide rail 20 is inserted into the accommodating portion 31 when the door 2 is opened.

The lower roller 50 includes a first lower roller 51 closely contacting the upper surface of the lower guide rail 20 and a second lower roller 52 closely contacting the protrusion 21c.

4 and 5, a concave portion 32 is formed on the lower side surface of the door panel 30, the concave portion 32 being concave upward, and the first lower guide roller is formed in the concave portion 32 And the circumferential surface thereof is brought into close contact with the upper surface of the lower guide rail 20. [

The second lower roller 52 is provided on both sides of the lower side of the door panel 30 so as to have a rotation shaft 52a in the up and down direction and has a concave groove 52b, into which the projection 21c is inserted, And is coupled to both sides of the lower guide rail 20.

2 and 3, in a state in which the door panel 30 is pushed to the left and the doorway 2 is closed, the lower guide rail 20 is guided by the magnet member 24, Is fixed to the bottom surface (3) so as to extend straight along the bar (60).

At this time, the door panel 30 is slid laterally to the lower guide rail 20 by the first and second lower rollers 51 and 52.

6, when the worker pushes the door panel 30 to the right to open the door 2, the rear end of the lower guide rail 20 is inserted into the insertion portion of the door panel 30 do.

When the operator pushes the door panel 30 to the left in a state in which the door panel 30 is moved to the right and the door 2 is opened, as shown in Fig. 2, The door panel 30 is slid to the left along the lower guide rail 20 so as to close the door 2. The door panel 30 is formed with a guide rail 20 extending outwardly and fixed to the floor surface 3. [

The sliding door constructed as described above is constituted by a plurality of support blocks 21 that are rotatably coupled to each other by a hinge shaft 22 extending in the lateral direction so that the lower guide rail 20 is vertically movable. The front end portion of the door panel 30 is fixed to the bottom surface 3 and the door panel 30 is formed with a receiving portion 31 in which the rear end of the lower guide rail 20 is received. The lower guide rail 20 is housed in the storage portion 31 of the door panel 30 when the door 2 is opened by pushing the door panel 30 in the lateral direction.

When the door panel 30 is pushed in the lateral direction to open the door 2, the lower guide rail 20 is exposed and the lower guide rail 20 is jammed or the lower guide rail 20 It is possible to prevent the door panel 30 from being slid smoothly in the lateral direction.

A guide bar 60 made of a magnetic material is embedded in the bottom surface 3 so as to be positioned below the lower guide rail 20 and the support block 21 of the lower guide rail 20 is embedded in the guide bar 60. [ The lower guide rail 20 is fixed to the bottom surface 3 so as to extend linearly along the guide bar 60 so that the lower guide rail 20 Is not firmly fixed to the bottom surface 3, and thus the lower end of the door panel 30 can be prevented from flowing.

The upper and lower guide rails 20 and 20 are fixed to the support block 21. The support block 21 has projections 21c projecting laterally on both sides in the longitudinal direction of the support block 21. The lower roller 50 includes a first lower roller And a second lower roller 52 closely attached to the protruding portion 21c so that the lower end of the door panel 30 can be firmly coupled to the lower guide rail 20. [

In the present embodiment, the storage compartment 31 is formed to extend upwardly from the door panel 30, but as shown in FIG. 7, the storage compartment 31 may extend laterally or be formed in various other forms .

It is also possible to further include a separate winding wheel for winding the lower guide rail 20 inside the door panel 30.

The tip end of the lower guide rail 20 is fixed to the bottom surface by the anchor bolts 23, but the tip end of the lower guide rail 20 can be fixed to the wall surface 1.

In addition, the support block 21 has a bottom surface formed as a flat surface. However, as shown in FIG. 8, the bottom surface of the support block 21 may be configured to be rounded so that its front and rear ends are upward.

When the lower side of the support block 21 is rounded, the door panel 30 is pushed in the opening direction, and when the lower guide rail 20 is inserted into the accommodation portion 31, The lower side of the block 21 can not be smoothly spaced from the bottom surface 3 and therefore it becomes very difficult to push the door panel 30 laterally.

That is, the support block 21 is fixed to the upper side of the guide bar 60 by the magnet member 24, so that when the support block 21 is simply pulled upward, .

When the support block 21 is pulled upward, the lower side of the support block 21 is pivoted in the lateral direction on the bottom surface 3 and is lifted upward so that the bottom surface 3 So that it is very easy to push the door panel 30 in the lateral direction.

The lower roller 50 includes a first lower roller 51 which is in close contact with the upper surface of the lower guide rail 20 and a second lower roller 52 which is in close contact with the protrusion 21c , The lower roller 50 may be configured to be in close contact with the upper surface of the lower guide rail 20 as shown in FIG.

To this end, a protruding portion 21d extending upward is formed on the upper surface of the lower guide rail 20.

The lower roller 50 is configured to have a laterally rotating shaft 53 and a circumferential surface thereof is formed with a concave groove 54 into which the protrusion 21d is inserted.

As such, the configurations of the lower guide rail 20 and the lower roller 50 can be variously changed.
