Description

Semi-automatic interlocking type door system {TRIPLE DOOR SYSTEM}

The present invention relates to an interlocking three-way sliding door provided to be interlocked with each other, specifically, a front panel of a furniture or a door, a movable partition wall, and the like, and can be opened and closed in a sliding manner. The present invention relates to a three-door sliding door system.

More particularly, the present invention relates to a semi-automatic interlocking type triple door system in which a door is semi-automatically closed. Specifically, after a driving door is opened by a user, a driving door is automatically closed by a pulling force application means, The present invention relates to a semi-automatic interlocking type three-way sliding door system in which a driven door closed in conjunction with a door is buffered by a buffer means to induce smooth closing of the driving door.

Generally, when a plurality of doors are installed in a sliding manner, an interlocking type triple sliding door has been introduced in which one door is opened or closed to open or close another door in a desired direction.

As a conventional technique related to this, there has been proposed a sliding door assembly (registered in Aug. 10, 2012), a domestic practical application (Japanese Patent Application No. 10-0724597) Registration No. 20-0439141 entitled "Triple sliding door interlocking device" (registered on March 31, 2008), domestic patent registration No. 10-0880272 "Interlocking device for sliding doors" (registered on January 22, 2009) -1195057 "Semi-automatic and interlocking triple sliding door assembly" (registered on October 22, 2012). Such prior art techniques are believed to be incorporated herein.

Japanese Patent Application No. 10-0724597 discloses that the opening / closing body linking device is installed along the upper rail, and the door is guided by the opening / closing body linking device.

Korean Utility Model Registration No. 20-0439141 discloses a triple sliding door interlock device capable of producing a triple-folded door by a simple structure.

Korean Patent Registration No. 10-0880272 discloses an interlocking device using a pulling belt having a gear portion instead of a wire.

Despite the various proposals of the interlocking triple sliding door, the interlocking triple sliding door developed until now has a very complicated structure and the installation work is not easy due to its complicated structure.

Meanwhile, the semi-automatic sliding door system is a sliding door system in which a door is automatically closed after a door is forcibly opened by a user.

In order to realize such a semi-automatic sliding door system, a door must be slidable in a horizontal direction relative to a door frame, and a pulling force application means such as a wire elastically supported by a spring is connected to the door, If the external force is not applied, the door is automatically closed by the pulling force application means. That is, the pulling force applying means continuously applies the pulling force to the door.

In addition, when the door is closed by the pulling force applying means, the closing speed of the door continuously increases, and a large shock occurs at the moment when the door is closed. In order to solve such a problem, a buffer means is provided.

The buffering means comprises a piston which normally projects out of the cylinder and the cylinder in the horizontal direction so as to provide a buffering force to the door before the door is closed to induce a smooth closing of the door.

As a conventional technology related to such a semi-automatic door system, Korean Patent Registration No. 10-1195057 entitled " Semi-automatic and interlocking triple sliding door assembly "(registered on October 22, 2012) was proposed.

Problems of such a semi-automatic sliding door system will be described.

In the semiautomatic sliding door system, the buffering means is of course separated from the door, but in order for the pulling force application means to continuously provide the pulling force, the pulling force application means need to be connected to the door.

When the pulling force application means is connected to the door by a wire or the like, a connection or separation operation between the door and the pulling force application means is required to install the door or separate the door from the door frame for maintenance.

In particular, when the door is separated from the door frame in a state in which it is not known that the door and the pulling force applying means are connected to each other, the operator may be injured by the connecting wire or the like.

Also, the conventional technique is provided in such a manner that the pulling force applying means and the buffering means are fixed to the outside of the door frame, which causes the door frame design to be coarse.

This embodiment mainly comprises three doors, specifically, a driving door 110, a driven door 120, a fixed door 130, a door interlock device 200, a guide panel 300, and a door frame.

The door frame comprises a lower door frame (not shown), a pair of side door frames 420 and 430, and an upper door frame 440.

The side door frames 420 and 430 are provided on both sides of the lower door frame 4 and the upper door frame 440 is provided across the upper side of the side door frames 420 and 430 to have a lattice form as a whole.

A guide panel 300 is fixedly installed at a lower portion of the upper door frame 440. The guide panel 300 and the upper door frame 440 are installed parallel to each other.

The driving door 110, the driven door 120, and the fixed door 130 are disposed parallel to each other in the space between the guide panel 300 and the side door frames 420 and 430 and the lower door frame .

Each of the doors 110, 120, and 130 is guided along the guide panel 300 and the lower guide portion of the lower door frame.

Meanwhile, the driven door 120 is disposed between the driving door 110 and the fixed door 130.

The guide panel 300 is formed as an extrusion molded product and has a guide rail 310 for a drive door, a guide rail 320 for a driven door, and a guide rail 330 for a fixed door. Of course, since the fixed door 130 does not move in this embodiment, the guide rail 330 for the fixed door is substantially unnecessary.

In addition, a guide rail 321 for the interlocking device is formed in a part of the guide rail 320 for the driven door.

The cross-sectional structure of the guide panel 300 can be seen in FIG.

The door interlock device 200 is provided so as to move along the guide rail 321 for the interlock device of the guide panel 300. [

The door interlock device 200 includes an interlock body 210, a pair of pulleys 220, a pulling belt 230, a drive door coupling 240, and a fixed door coupling 250, as shown in FIG. .

The interlocking body 210 includes a body 211 extending along the longitudinal direction of the door and a pair of side guides 212 fixed to both sides of the body 211 in the longitudinal direction.

The side guide body 212 has a shape corresponding to the guide rail 321 for the interlock device of the guide panel 300 (refer to FIG. 5), and as a result, the interlock body body 210 is attached to the side guide body 212 Thereby sliding along the guide panel 300.

In addition, a pair of driven door through holes 211a are formed in the bottom body 211. [

On the upper surface of the bottom body 211, a pair of pulleys 220 are disposed apart from each other.

Further, a pair of pulleys 220 is equipped with a pulling belt 230 which forms a closed loop.

A connecting rod 240 for the driving door is fixed to one side of the pulling belt 230 and a connecting rod 250 for the fixed door is fixed to the other side of the pulling belt 230.

The driving door connecting rod 240 is formed with a driving door through hole 241 and the fixed door connecting rod 250 is formed with a through hole 251 for a fixed door.

The driving door connecting rod 240 and the fixed door connecting rod 250 are not only fixed to the pulling belt 230 but also engaged with the bottom body 211 as shown in FIG.

That is, the driving door connecting rod 240 and the fixed door connecting rod 250 move in conjunction with the pulling belt 230, and in particular, they are guided by the bottom body 211 to move stably.

A driven door (120) is disposed directly below the door interlock device (200).

A pair of vertical doors 121 for the driven doors are fixed to the upper portion of the driven doors 120.

The vertical member 121 for the driven door is arranged to pass through the through-hole 211a for the driven door of the door interlock device 200. [

With this structure, the driven door 120 can move at the same speed as the door interlock device 200 in the same direction.

A vertical member 111 for the driving door is fixed to the upper portion of the driving door 110 provided at one side in the width direction of the driven door 120 and a fixed door 130 provided at the other side in the width direction of the driven door 120 A vertical member 131 for a fixed door is fixedly provided.

One of the pair of vertical drive members for the drive door 111 is disposed to penetrate the drive door through hole 241 of the drive door connecting rod 240 and the vertical members 111 for the pair of fixed doors And one is disposed to pass through the through-hole 251 for the fixed door of the connecting rod 250 for the fixed door.

 The vertical member 111 for the driving door, the vertical member 121 for the driven door and the vertical member 131 for the fixed door are all of the same shape as in FIG. 8, and each of the vertical members 111, 121, And rollers 111a, 121a, and 131a are provided at the upper end of the roller.

Each of the rollers is referred to as a drive door roller 111a, a driven door roller 121a, and a fixed door roller 131a.

Each of the rollers 111a, 121a, and 131a is formed in a cylindrical shape so that only the side surface thereof is in contact with the guide rails 310, 320, and 330 and is rolled.

In addition, the fixed door 130 is kept fixed by other fixing means.

In this state, when the driving door 110 is slid, the driven door 120 is slid in the same direction as the driving door 110 by the door interlock device 200, .

On the other hand, the driving door 110 and the driven door 120 receive only the horizontal movement force from the door interlock device 200 and do not have any coupling structure.

The drive door 110 and the driven door 120 are driven by the driving roller for the driving door 111a and the driven door roller 121a at the upper portion of the guide door 110 and the driven door 120, (320) so that no load in the vertical direction is received.

Therefore, the drive door 110 and the driven door 120 can be easily driven by a very small force.

Also, each of the doors 110, 120, and 130 can be directly separated from the guide panel 300 or the door interlock device 200 without any structural change.

Hereinafter, the pulling force applying means 600 will be described.

In this embodiment, the pulling force application means 600 is provided at the lower portion of the guide panel 300. [

The pulling force applying means 600 includes a wire 601 which is resiliently supported by a spring as in the prior art, and the wire 601 is connected to a connecting rod 240 for the driving door.

The pulling force applying means 600 applies a pulling force to the driving door 110 at all times via the connecting door 240 for the driving door. When the driving door 110 is opened and no additional external force is applied to the driving door 110, (110) is automatically closed by the pulling force application means (600).

This structure has an advantage in that, in the present embodiment, when the driving door 110 is installed or removed, there is no need to consider the assembly relationship with the pulling force application means 600. [ The pulling force applying means 600 directly pulls the driving door 110 and it is necessary to always assemble or separate the pulling force applying means 600 when the driving door 110 is installed and removed.

On the other hand, for connection with the pulling force applying means 600, the connecting door 240 for the driving door may be provided with an assembling groove or an assembling protrusion.

In addition, in this embodiment, the buffer means 700 is also fixed to the lower portion of the guide panel 300. [

The buffering means 700 comprises a cylinder 710 and a piston 720 which projects horizontally from the cylinder 710 as in the prior art.

A general description of this buffer means 700 is replaced by the above-mentioned conventional techniques.

The buffer means 700 provides a buffering force to the driven door 120 when the driven door 120 is moved in the closing direction, thereby relieving the closing of the driving door 110.

To this end, the buffer means 700 is located on the extended surface of the driven door 120.

That is, the shock absorber 700 is provided to prevent the drive door 110 from hitting against the door frame. However, the shock absorber 700 provides buffering force to the driven door 120 to provide an indirect shock to the drive door 110.

Hereinafter, the shock absorbing means 700 of this embodiment will be described with particular reference to Fig.

A buffer plate 122 made of a metal material is provided on the upper part of the driven door 120.

In this embodiment, the buffer plate 122 is fixed to the upper portion of the driven door 120 in the form of a letter.

Since the buffer plate 122 is fixed to the driven door 120, the buffer plate 122 moves in conjunction with the driven door 120.

On the other hand, the housing 721 is mounted on the tip of the piston 720, and the first bolt 722 is fixed to the center of the housing 721 in the horizontal direction.

The first bolt 722 is formed with a first screw thread 722a.

Only one end of the coil spring 723 is wound around the first thread 722a along the first thread 722a so that the coil spring 723 is inserted into the housing 721 To the piston 720. As shown in Fig.

The coil spring 723 is disposed in the horizontal direction.

The coil spring 723 is a symmetrically formed conical coil spring, and has a convex shape at the center in the longitudinal direction.

And a magnetic body 724 is provided at the other end of the coil spring 723. [ The magnetic substance 724 is intended to be magnetically coupled with the buffer plate 122 made of a metallic material.

A second bolt 725 is provided while passing through the magnetic substance 724 and the second bolt 725 is disposed in a horizontal direction toward the first bolt 722. [

A second thread 725a is formed on the second bolt 725 and the other end of the coil spring 723 is wound on the second thread 725a and fixed to the second bolt 725.

A rubber cover 726 is provided on the surface of the magnetic body 724 facing the buffer plate 122.

The rubber cover 726 is for preventing the noise generated when the magnetic substance 724 and the buffer plate 122 are in contact with each other and the rubber cover 726 is assembled while the magnetic substance 724 is inserted.

Meanwhile, the housing 721 is formed so as to surround the spring 723 so that the spring 723 and the like can not be confirmed from the outside.

As described above, the pulling force application means 600 and the buffer means 700 of the present embodiment are located inside the upper door frame 440 and are not visible from the outside, thereby enabling a simple design of the door system.

Hereinafter, the operation of the present embodiment will be described.

10, the user moves the door 110 in a direction to open the door 110. When the driven door 110 is opened, the user moves the driven door 110 by the interlocked operation of the door interlock device 200, It is also moved in the open direction.

When the driven door 120 moves in the opening direction, the piston 720 protrudes from the cylinder 710 together with the driven door 120 (due to the magnetic coupling between the buffer plate 122 and the magnetic body 724) The piston 720 and the driven door 120 are separated from each other so that the piston 720 maintains its position and only the driven door 120 is opened. That is, the state shown in Fig.

When the driven door 120 is automatically closed by the pulling force applying means 600, the buffer plate 122 of the metal material provided on the upper portion of the driven door 120 contacts the tip of the piston 720, 726, the driven door 120 is changed to the state shown in FIG. 10 while dragging the piston 720.

Then, when the driven door 120 is opened again, the piston 720 is drawn again.

At this time, the cushioning plate 122 of the metallic material provided on the upper portion of the driven door 120 and the magnetic body 724 provided at the tip of the piston 720 are maintained in the engaged state by the magnetic force coupling.

In this process, the present embodiment can assure a reliable coupling state between the buffer plate 122 and the magnetic body 724 for the following reason.

In this embodiment, since the magnetic substance 724 is installed via the coil spring 723, when the magnetic substance 724 receives an external force, it can be shaken up and down to some extent.

The range in which the magnetic substance 724 can be shaken is limited by the housing 721.

The coil spring 723 for supporting the magnetic body 724 is always a coil spring 723 of a conical shape formed by symmetrically forming the conical coil spring so that the magnetic body 724 is always elastically supported so as to be positioned in the horizontal direction.

Of course, depending on the embodiment, the coil spring 724 may be used as a conical coil spring, but in this case, it is a problem to fixedly couple the conical coil spring to the magnetic body 724 to the housing 721. [

In this state, when the magnetic substance 724, specifically the rubber cover 726, comes into contact with the buffer plate 122, even if the piston 720 does not have a perfect straightness in the horizontal direction, And is restored to a posture that maintains the complete horizontal state by the coil spring 240.

Therefore, in spite of the posture of the piston 720 just before the contact, the magnetic substance 724 and the buffer plate 122 are combined in a state of being in a completely horizontal state, so that a perfect magnetic coupling can be achieved.

Therefore, there is no danger that the magnetic body 724 is unintentionally disengaged from the buffer plate 122.

Therefore, the piston 720 of this embodiment always protrudes to the longest stroke when the driven door 120 is opened, and restores to the original position while providing a sufficient buffering force when the driven door 120 is closed. It is possible to solve the problem of shock and noise due to abrupt closing of the motor.

It will be understood by those skilled in the art that the foregoing description of the present invention is for illustrative purposes only and that those of ordinary skill in the art can readily understand that various changes and modifications may be made without departing from the spirit or essential characteristics of the present invention. will be. It is therefore to be understood that the embodiments described above are intended to be illustrative, but not limiting, in all respects. For example, each component described as a single entity may be distributed and implemented, and components described as being distributed may also be implemented in a combined form.
