CENTER ROLLING DEVICE FOR TELESCOPIC TYPE SLIDE DOOR}

The present invention relates to a center roller device for a slide folding door, and more particularly, to a center roller device for a slide folding door for guiding the slide door to be freely folded and unfolding while guiding the slide door to enable a rolling motion on the slide rail. It is about.

Generally, various types of doors are installed in residential and office spaces and various buildings.

For example, in a residential building such as an apartment, a slide door is provided between the living room and the balcony to divide the living room and the balcony into spaces.

The slide door has a roller track that enables rolling motion on the door itself to guide the slide motion and a rail track of a suitable shape for enabling slide motion along the mating structure.

In order to form the movement trajectory of the slide door while supporting and supporting the slide door, a slide rail corresponding to the rail track of the slide door is provided on the bottom surface and the ceiling surface, respectively.

Depending on the type of slide door, it is known in various formats such as transverse moving type, sliding interlocking overlap type folding type, and slide folding door type.

The general transverse movement type is as shown in Fig. 1, in which the door is opened and closed sideways in the lateral direction.

Fig. 1 schematically shows a transverse moving type slide door type. Fig. 1 (a) is a plan view and Fig. 1 (b) is a sectional view taken on line A-A 'in Fig.

The lateral movable slide door structure is divided into a fixed side door 10 and a movable side door 20 for convenience. The movable side door 20 overlaps the fixed side door 10 and slides in an overlapping manner.

The fixed side door 10 and the movable side doors 20 of the slide door move along the slide rail 40 provided on the floor surface 30. Although not shown in the drawings, the fixed side door 10 is also known in which a roller is installed to improve the sliding performance, and the rolling motion is induced in the slide rail 40. Here, the slide rail 40 is installed not only on the bottom surface 30 but also on the ceiling surface. FIG. 1 shows an example in which a slide rail 40 is provided on a floor surface 30.

In general, in the transverse moving type slide door type, a certain height step 'H1' is formed from the bottom surface 30, which is an installation target structure of the slide rail 40. Further, at least two rails are required even in the minimum open-close structure that is divided into the fixed-side door (10) and the movable-side door (20).

When the nut 620a is rotated, the distance between the rotating shaft 600a and the screw coupling shaft 710a of the roller head 800 can be adjusted, so that If the vertical degree is poor, by rotating the nut 620a, the height of the center roller 410a coupled to the slide rail 101 can be easily adjusted from the outside.

In addition, by sliding the latch bolt 660 formed at the lower end of the rotary shaft 600a with a tool, the insertion depth of the screw portion 610a, which is lodged in the screw coupling shaft 710a of the roller head 800, can be adjusted from the outside. If the vertical degree is confirmed before and after construction, the latch bolt 660 can be adjusted from the outside without disassembling the center roller 410a to adjust the vertical state of the slide door.

As such, the height adjusting means of the center roller 410a includes a latch bolt 660 and a nut 620a is installed on the threaded portion 610a of the rotating shaft 600a so that the screw coupling shaft 710a of the roller head 800 side is provided. It is configured to adjust and regulate its location.

Meanwhile, FIGS. 8 to 14 are guides for guiding and guiding the slide door 200 to be folded and unfolded along the lower slide rail 100 in conjunction with the center roller 410a of the slide folding door of the present invention. It is a reference figure about the specific structure of 400. As shown in FIG.

The center roller 410a according to the present invention has another slide door 200 adjacent to each other except a pivot part 500a for fixing the side slide door 200 on one side to the rail groove 110 on the slide rail 101. The frame 210 of the slide to fold so as to be movable along the rail groove 110 of the slide rail 101 to expand.

The center roller 410a hinges the upper ends of the frame 210 separately from the hinge 300 to seat the frame 210 of the slide door 200 to the rail groove 110 of the slide rail 101. It is combined and seated in the rail groove 110 of the slide rail (101).

According to the center roller device of the slide folding door according to the invention the frame of the slide door 200 while guiding the folding movement of the slide door 200 along the slide rail 101 freely without moving flow through the center roller (410a) The rotation axis 600a of the center roller 410a reduces movement constraints and operability of the slide doors 200 generated by the height step of the frame 210 in the step of horizontally fitting the 210 to the slide rail 101. By adjusting the height can be solved by adjusting the vertical degree of the entire slide door 200.

The lower side moving structure moving along the lower side slide rail 100 and the lower side slide rail 100 is a structure interlocking with the center roller 410a of the present invention, but is not directly related to moving along the lower slide rail 100. The detailed operation of the movement guide 400 will be omitted.

The center roller 410a functions to seat the slide door 200 along the rail groove 110 of the slide rail 101.

An example of the upper structure of the slide folding door is a pivot 500a for fixing the side slide door 200 on the rail groove 110 of the slide rail 101.

The frame 210 of the slide door 200 coupled through the pivot part 500a is located at the side of the side. The frame 210 of the slide door 200 coupled to the slide rail 101 by the pivot portion 500a does not move along the slide rail 101, but the frame 210 is stopped on the slide rail 100. Fix it.

The center roller 410a except for the pivot part 500a couples the frames 210 of the slide doors 200 adjacent to each other through the hinge plate 430a to fold the rotating shaft 600a and the hinge part 300 by the axis. Allows swinging motion to be folded.

For example, in the case of a four-slide door, the total number of frames 210 is eight.

The first frame 210 is seated and coupled to the rail groove 110 of the slide rail 101 through the pivot portion 500a, and the second frame 210 and the third frame 210, and the fourth and The fifth frame 210 and the sixth and seventh frames 210 are coupled to the slide rail 101 so that they can be folded through the center roller 410a, and the upper and lower slides are provided on the eighth frame 210 located on the outermost side. The end guide 420 which is movable along the rails 100 and 101 is mounted.

When the eighth frame 210 is pushed in the direction in which the first frame 210 is positioned, the end guide 420 moves along the rail groove 110 of the upper and lower slide rails 100 and 101, and the slide door 200 in order. ) Are folded around the center roller 410a and the hinge part 300. The frame 210 on which the end guide 420 is mounted moves horizontally along the slide rail 100 in the pushing direction, and at the same time, the horizontal and vertical rolling rollers 801 and 802 which are rollers of the center roller 410a are slide rails. The vertical wall surface of the rail groove 110 of the 101 and the horizontal surface in contact with an even distribution of force to move smoothly in the direction of the force acting while rolling movement and finally the interval of all the frames 210 is narrowed to the maximum To reach. This state is a state where the slide folding door is opened.

On the contrary, when the frame 210 of the outermost side slide door 200, that is, the eighth frame 210 is pulled in the direction opposite to the direction in which the eighth frame 210 is pushed in the direction of the first frame 210, the respective frames 210 are slide rails 101. When the gap was narrowed along the gradual gap and pulled to the end, it finally extended to a position parallel to the slide rail 101 to reach a parallel state. In this state, all the frames 210 are parallel to the upper and lower slide rails 100 and 101, and at the same time, the slide door 200 is not folded and the closed state of the door is fully extended.

As such, the center roller 410a in the slide folding door is a part which induces movement on the slide rail 101 by combining the frames 210 of the slide doors 200 adjacent to each other as the center roller 410a of the present invention. Induces the rolling motion through the roller portion to be freely moved along the rail groove 110 of the slide rail 101 in the horizontal and vertical direction without shaking and flow to improve the operation reliability of the slide door 200 and at the same time Inhibit the shaking flow in the rail groove 110 of the 101 to reduce the operating noise.

In addition, when there is a change in the height of the slide door 200 caused by the vertical axis displacement during installation and construction stages and use of the slide door 200, the height of the vertical axis by adjusting the height adjustment means installed in the center roller (410a) as necessary It is also possible to match the height uniformly with other neighboring vertical heights.

When the height of the frame 210 of the slide door 200 forms a horizontal level relative to the slide rail 101, an ideal folding motion of the slide door 200 appears along the rail groove 110 of the slide rail 101.

The folding reference axis of the slide door 200 includes the hinge portion 300 and the pivot portion 500a, and the center roller 410a, the center guide 410 and the end guide 420.

The frame 210 positional reference of the preferred slide door 200 along the slide rail 101 is a position perpendicular to the transverse axis of the slide rail 101 and the frame 210 of the vertical axis and is also framed on the slide rail 101. Normal operation of the slide door 200 is possible when a constant level is achieved without the height step of 210.

If there is some height step of the frame 210, the movement of the slide door 200 on the slide rail 101 is generated or the smooth and smooth movement of the slide does not appear, and the operation noise is also generated.

The cause of the vertical height difference generated in the frame 210 may be caused by the pivot portion 500a and the center roller 410a, the center guide 410 and the end guide 420 in the installation and construction stages. It may not be the same height or may occur due to the difference in the length of the frame (210).

The vertical axis imbalance that can be caused by various causes can be easily corrected or adjusted by adjusting the height of the rotating shaft 600a of the center roller 410a.

The end of the rotating shaft 600a is made of a latch bolt 660 that can be turned by inserting a tool, and the upper side is made of a threaded portion 610a so that the height of the rotating shaft 600a can be adjusted according to the amount of rotation that is turned through the tool.

In addition, the center roller 410a according to the present invention is shown as an example mounted on the upper side slide rail, but similarly, the lower side may be installed in the same structure as the upper side.

The present invention allows the vertical height of the slide door 200 located on the slide rails 100 and 101 to be adjusted by adjusting the height of the rotating shaft, thereby reducing the operability caused by the eccentricity of the slide door 200. There is an advantage that can improve various problems resulting from abnormal installation of the slide door installed outside the vertical straightness, such as operating noise.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments.
