Description

[0001] The present invention relates to a damping system having a sliding type three door,

[0001] The present invention relates to a damping system for a sliding door with three doors, and more particularly, to a sliding door system having damping systems independent of the left and right doors and the central door, Not only the complete damping is performed during operation but also the damping operation is performed regardless of whether the central door is opened or closed in the left or right direction.

In addition, the present invention is an improvement on the registered utility model 20-0459418 of the present applicant.

Most of the doors installed in the furniture such as the wardrobe which is widely used at home have adopted a hinged opening / closing method in which one side is opened to the front with the hinge as the axis. Since such a hinged door opens and closes toward the front, There was a structural problem that occupied much.

Further, since the hinge supporting the door can not support a large load due to its structural characteristics, it is difficult to apply a heavy-weight door such as a door made of a metal such as aluminum, titanium, or stainless steel to furniture, There is a limitation in constructing doors of various kinds of materials such as wood.

In order to solve the above-mentioned problem, in recent years, a door of a slide opening / closing type has been widely applied in which a hinged opening / closing method is improved.

The basic structure of the slide type door is such that the upper and lower rails are horizontally installed on the top plate and the upper plate and the lower plate of the wardrobe respectively and the doors separated by the out door and the in door are positioned inside and outside And an upper roller and a lower roller that are assembled to the upper and lower rails, respectively, and are slidably mounted on the upper and lower rails are installed by brackets, respectively.

At this time, the upper roller is installed vertically by brackets at the upper part of each door and is guided side by side on the upper rail, and the lower roller is horizontally installed on the lower part of each door by the bracket so as to be guided to the lower rail. .

Therefore, the upper and lower rollers of the outdoor and indoor rollers are assembled to the upper and lower rails provided on the upper and lower panels, respectively, and guided by the upper and lower rails, respectively.

However, such a slide-type door is closed at a rapid speed due to overspeed in the process of being opened and closed, so that a user's hand or a finger is caught, thereby causing a safety accident. In addition, There is a structural problem that the related parts of the other wardrobe are broken or the balance is distorted.

In order to solve this problem, it is required to provide a buffering member, which is a separate safety means for buffering, at the end portion of the rail guided by the door so as to buffer the door closing speed as much as possible.

A variety of safety mechanisms have been proposed in the past. For example, the stopper may be formed in a clip shape that can be widened and contracted by its own elasticity, fixed on a rail, The door is formed with an insertion port that can be inserted into and detached from the stopper. The door is stably stopped by inserting the insertion port into the stopper in the process of closing the opened door.

In another conventional structure, a buffer made of a flexible synthetic resin or a rubber material having a hollow portion therein is formed and installed at the end of the rail to buffer the door when the door is closed.

However, according to the above-mentioned conventional structure, since it is only providing the function of holding the door at the last stage of the door operated by the slide type in the case of the former, it is difficult to effectively reduce the closing speed of the door, There is a structural problem that it is difficult to fully buffer.

Also, in the latter case, although the impact of the strongly closed door may provide a function of buffering to some extent, it also has the problem of the former because the closing speed can not be reduced. In addition, There was also a problem.

Accordingly, in order to solve the above-mentioned problems, the present applicant has proposed a damping system of a furniture having a sliding door of Registration Utility Model No. 20-0459418.

The damping system of the line registration design includes an upper rail horizontally installed on an upper portion of a front of a wardrobe, a damping stopper for an outdoor and an indoors staggered on upper and lower surfaces of the upper rail, The damping stopper is operated according to the opening and closing of the door so as to improve the operability and safety of the sliding door by providing the operating member which is provided on the bracket fixed to the door and the indoor and operates the damping stopper according to the opening and closing operation of the door. Thereby minimizing the installation space of the damping stopper, thereby improving the structure.

However, the above-mentioned line registration design is adapted to two doors or four doors constituting a pair of outdoor and indoor doors, so that a central door composed of left and right doors and outdoor, which are indoors, It is difficult to apply the present invention to a three-door system.

In the above-described conventional configuration, since a pair of outdoor and indoor units are slid left and right only within the respective ranges, that is, the indoor unit is slid within the range of the outdoor unit or the outdoor unit is slid only within the range of the indoor unit Even if a damping stopper is provided only on the left and right end portions of these members, the required effect can be expected.

On the other hand, in the slide-type three-door system, left and right doors corresponding to Indic languages can be damped by the damping system described above, but the central door corresponding to the outdoor should slide at least in either the left or right direction There is a structural problem that is difficult to apply to the above-described damping stopper.

That is, the center door must be opened and closed in either the left or right direction, or, in the case where the door is opened and closed, it must be stopped at the precise position of the center portion. However, such a damping stopper can not satisfy such a condition .

Also, in addition to the above-mentioned line registration scheme, there is a damping system of a slide door proposed in the past, but this has also a structural problem that is difficult to apply to a slide type three door required in the present invention.

For example, a damping system that can mitigate the impact of a slide door by using various cylinders has been proposed as a damping system of the conventional slide type door.

This is a "damper device under furniture door" proposed in Korean Patent Registration No. 1071528, which is installed on the lower rail of the furniture body to contact the lower roller assembly side of the door to close the door, An auxiliary damping device is provided.

However, since such a damper device adopts a single damper configuration, it may be advantageous to stably stop the door while balancing the top and bottom of the door, but as one damper device, noise and shock generated when the door is opened and closed can be effectively prevented There is a problem that it is impossible to apply the present invention to a structure in which three doors required in the present invention are mounted.

In addition, there have been proposed a domestic utility model No. 368521 "a hinge device equipped with a gas damper" and a domestic patent No. 663751 "a furniture damper", but most of them are suitable for a door which is opened or closed by a support point There has been a structural problem in that it can not be applied to the three-door system required in the present invention even if it is a shock absorber of a sliding door.

The object of the present invention is to provide a damping system of a sliding door having three sliding doors adapted to a three-door sliding sliding door.

Particularly, the present invention is an improvement of the registered trademark Utility Model No. 0-0459418 of the present applicant, so that a damping system can be realized even in a three door system.

It is another object of the present invention to provide a damping system of a prolonged door having a sliding type three door which can open and close a central door corresponding to an out door in any direction left and right as well as damping in any direction have.

In order to accomplish the above object, the present invention is configured to be suitable for a room having a door having a three-door structure including a central door corresponding to left and right doors and an outdoor door corresponding to an indoor room even in a long room having a sliding door do.

In the present invention, upper and lower rails are provided on the upper and lower surfaces of the elbows, respectively, and a pair of damping stoppers for the left and right doors are provided on the lower side of the upper rail so that the left and right doors are slide- So that the damping operation is performed while the opening and closing operation is performed.

In addition, the central door includes a damping stopper that can perform a damping action when the center door is opened at both side ends of the upper side of the upper rail, and a bidirectional damping stopper for only the center door at the upper inner side of the center door, The door can be opened and closed in either the left or right direction, so that the damping operation is performed.

The damping system according to the present invention is a three-door type damping system comprising a pair of left and right doors corresponding to the inner door and a central door corresponding to the outer door while being opened and closed at the center of the left and right doors, There is an advantage that it can be applied suitably to the chest.

Particularly, the present invention is advantageous in that the center door is opened or closed in either the left or right direction, and at the same time, the damping operation is performed, so that the chest can be installed indoors under any condition.

In the damping system of the present invention, not only the left and right doors, but also the damping operation is performed so that the center door is independently controlled by the respective damping stoppers, safety and operability according to the operation can be expected.

The damping stoppers 60 and 60a for the center door of the center door 10 are operated when the center door 10 is fully opened to the left or completely opened to the right. 33 are provided on both sides of the operation plate 70.

That is, when the center door 10 is slidably opened in one of the left and right directions, the operation plate 60 in the corresponding direction operates the damping stoppers 60 and 60a in the corresponding directions, It gradually decays and stops.

Left and right damping stoppers 60b, 60c, 60d, and 60e for damping the left and right doors 20 and 30 are provided at predetermined positions on the left and right sides, do.

Damping stoppers 60b and 60c for damping operation of the left door 20 are provided at a predetermined interval on the left side of the center portion of the upper rail 40 so that the stroke distance of the left door 20 On the other hand, damping stoppers 60d and 60e for damping operation of the right door 30 are provided at a predetermined interval on the right side to limit the stroke distance due to opening and closing of the right door 30.

At this time, an operation upper plate 70 for operating the damping stoppers 60b, 60c, 60d, and 60e is installed on the outer upper bracket 23 of the left and right doors 20 and 30, The operation plate 70 is installed on the upper bracket 23 in the outward direction among the upper brackets 23 of the respective doors so that the left and right doors 20 and 30 are slidable in the other direction .

The damping stoppers 60a and 60a for the center door and the damping stoppers 60b, 60c, 60d and 60e for the left and right doors have the same structure and only one of them will be described.

The damping stoppers 60a, 60b, 60c, 60d and 60e are shown in more detail in FIGS. 9 to 14 in that the coupling grooves 41, 42 of the upper rail 40, With a long bar body 61 so that it can be inserted and fixed along the lengthwise direction of the upper rail 40 by means of a clip 62 on one side.

An actuating hole 64 having a pair of hooking protrusions 64a and 64b protruding upward is provided on the body 61 by a guide pin 67 on one side while being elastically provided by a cylinder 65 and a tension spring 66, Is configured to be moved back and forth along the guide groove (68) of the body (61).

At this time, the guide groove 68 is formed horizontally on the side surface of the body 61, and the front end is bent in a direction perpendicular to the downward direction to have the stop groove 69 so that the guide pin 67 of the operation hole 64 is slid .

The operating member 64 is connected to the cylinder 65 as a piston rod inside the body 61 so that the oil filled in the cylinder during the forward operation is moved from the one chamber to the other chamber through the orifice, A spring 66 is connected to provide the function of returning the actuating opening 64 advanced by its tensile force back to its original position.

However, in the present invention, the structure of the damping stopper is changed so that the damping stopper can be easily and fastened in the coupling grooves 42 and 43 of the upper rail 40, So that it can be suitably applied to a sliding type door.

A pin-shaped operation member 80 is fixed to a central portion of the upper rail 40 so as to perform a damping operation according to opening and closing operations of the central door 10. [

16 and 17, the center door 10 is mounted on the left and right doors 20 and 30 so as to be slightly overlapped with the upper and lower brackets 33 The upper and lower rollers 21 and 32 are seated on the upper and lower rails 40 and 50 by the upper and lower rails 34 and slide in the left and right directions.

As shown in FIGS. 3, 4, 16 and 17, the upper and lower brackets 33, 34 are provided on both sides of the central door 10, A bidirectional damping stopper 90 is provided.

The bidirectional damping stopper 90 functions to damp the damping operation while the center door 10 is slidably opened in one direction and closed at the center, and to stop the damping stopper 90 at an accurate position.

This bidirectional damping stopper 90 is shown in more detail below in FIG. 18 of the accompanying drawings, which is fastened and fixed to the upper portion of the center door 10 through a bracket 91 in a horizontal direction, thereby damping in both directions.

The bidirectional damping stopper 90 includes a body 92 mounted on a bracket 91 and pneumatic cylinders 93 provided on both sides of the body 92. The pneumatic cylinder 93 is provided with a piston 94, Is connected to the piston rod 95 and is operated in the forward and backward directions.

The body 92 is provided at the center thereof with a conveying port 96 which is operated by an operating member 80 provided at the center of the upper rail 40 and which is conveyed to the left and right. The piston rod 95 is moved to the left and right along the inner guide groove 97 of the body 92 while being connected by the guide pin 96a, And an axial groove 96c, which is opened horizontally alternately to both sides, is formed before and after the upper portion.

The transfer opening 96 is guided by the inner guide groove 97 along the left and right longitudinal direction within the body 92 so that the center door 10 is moved in the transport opening 96 during the left and right opening / The engagement groove 96b formed on the bottom surface of the body 92 is engaged with the operation member 80 and is conveyed along the body 92 so as to compress the pneumatic cylinder 93 in the conveying direction.

At this time, the inner guide groove 97 is formed on the front and rear sides of the operation space of the body 92 to which the feed port 96 is to be conveyed, and has curved surfaces upward at both side ends thereof, It is separated from the horizontal operating line and stopped at the same time.

The body 92 is provided with return means for returning the delivery port 96 to the original position on both the front and rear sides of the body 92. This is provided with another outer guide groove 98 on the front and rear outer sides of the body 92, The operating piece 99 is moved by the tension spring 101 to move the operating piece 99. [

The outer guide grooves 98 are provided symmetrically in different directions on the front and rear sides of the body 92 so as to function as a guide for guiding each of the operating pieces 99 fastened thereto in the horizontal direction, (101) is installed by connecting the operating piece (99) and the pneumatic cylinder (93).

A shaft pin 99a protruding inward is formed on the inner side of each of the operating pieces 99 so as to be engaged or disengaged with a corresponding shaft groove 96c of the conveying hole 96 to be conveyed and is operated by the conveying port 96 .

That is, since the axial pin 99a of the corresponding actuating piece 99 is inserted into the axial groove 96c of the conveying mouth 96 according to the conveying direction of the conveying mouth 96, When the feed force of the conveying port 96 is released, the tension spring 101 returns to its original position due to the tensile force of the tension spring 101.

The conveying port 96 is gradually advanced by being compressed by the pneumatic cylinder 93 while the conveying port 96 is being guided by the inner guide groove 97 and the curved surface section It is possible to maintain the stationary state at the same time when it is out of the same operating line.

Accordingly, the present invention configured as described above can be suitably used not only for the sliding type three doors, namely, the left and right doors 20 and 30 and the long door having the central door 10, The same effect can be expected even when applied to various types of three doors.

As shown in the accompanying drawings, the left door 20 and the right door 30 are operated on the same principle except for the left and right positions, and here, the left door 20 ) Will be described below.

In other words, when the left door 20 is opened toward the center to open the door 20 in a closed state, the operation plate 70 provided on the upper bracket thereof is engaged with the operation hole 64 of the outer damping stopper 60, The hydraulic cylinder 65 connected to the piston rod is moved from one side to the other side while the one side engaging jaw 64a of the piston rod is pushed forward and advanced forward as shown in Fig. The guide pin 67 is advanced to a position where it is inserted into the front end stop groove 69 of the guide groove 68 and then stopped.

At this time, the stop groove 69 is formed to be bent in a substantially right angle direction, thereby limiting the stroke distance due to the forward movement of the guide pin 67, and releasing the slide path from the guide groove 68, The engaging protrusion 64a of the opening 64 is released from the path to allow continued advancement of the operating plate 70 fixed to the left door 20. [

Therefore, the left door 20 is slidably opened without any resistance and reaches the other damping stopper 60a on the other side.

At this time, after the damping stopper 60a is first opened and closed once, the left door 20 is operated as described above, thereby maintaining the state shown in FIG. 14B.

In this state, the operation plate 70 of the left door 20 actuates the damping stopper 60a on the opposite side. The operation plate 70 pushes the rear jaw 64b of the operation opening 64, The guide pin 67 is retracted from the stop groove 69 to be retracted along the guide groove 68 and the tensile force of the expanded tension spring 66 So that the actuating member 64 is actuated backward.

At this time, since the operating rod 64 is connected to the hydraulic cylinder 65 by the piston rod, the oil filled in the operating rod 64 is returned to the original position through the orifice in the process of being returned by the tension spring 66 The left door 20 is gradually decelerated and stopped.

The damping stopper 60a attenuates the speed of the left door 20 and stops the operation of the left door 20 safely so that the operation plate 70 is moved to the operation hole 64 of the inner damping stopper 60a And waits for the next operation while maintaining the combined state.

On the other hand, the right door 30 has a structure symmetrically symmetrical with the left door 20, and operates in the same manner as the operation of the left door 20 according to the same constitution, The damping operation is performed.

The central door 10 is required to be opened and closed accurately in either the left or right direction due to the structural characteristics of the three doors and damping must be securely performed.

The central door 10 according to the present invention is provided with a separate operation member 80 fixed to the central portion of the upper rail 40 and opened and closed by the operation member 80 as a reference point.

When the central door 10 is closed, the conveying port 96 of the bidirectional damping stopper 90 installed on the upper portion of the central door is engaged with the operation member 80 fixed on the upper rail 40, .

When the central door 10 is opened in one direction to open the central door 10, that is, opened to the right as shown in the drawing, the transfer port 96 is also transferred by the transfer of the central door 10.

That is, the feed port 96 is guided along the inner guide groove 97 of the body 92 while the guide pin 96a is conveyed. At this time, the shaft groove 96b formed on the upper portion of the feed port 96 is moved to the right And is coupled with the shaft pin 99a of the corresponding actuating piece 99 so that the actuating piece 99 is simultaneously transferred.

The operating piece 99 is guided by the outer guide groove 98 formed on the outer side of the body 92 and at the same time is transported together with the transporting opening 96 while stretching the tension spring 101.

The conveying port 96 is conveyed to a curved surface section bent toward the upper side while the guide pin 96a is conveyed to the end along the inner guide groove 97 and the conveying port 96 is rotated by the curved surface section, The engagement groove 96b of the delivery port 96 is completely disengaged from the operation member 80 by the operation of the central door 10 which is released from the horizontal line of the guide groove 97 and continues to be opened.

Therefore, when the central door 10 thus opened reaches the right end of the chest 100, the damping stopper 60e (60e) provided on the upper side of the upper rail 40 can be easily opened to the right without any resistance, The damping operation is performed.

This operation is the same as that of the damping operation of the left door 20 already described above. The operation of the damping operation of the left door 20 is omitted here. That is, the operation plate 70 installed on the upper bracket 33 of the center door 10 is connected to the damping stopper The damping operation is performed when the center door 10 is opened in the right direction by operating the first door 60a.

The bidirectional damping stopper 90 of the conveying port 96 is completely conveyed to one side along the inner guide groove 97 and is stopped, State.

When the center door 10 is closed in this state, the operation member 80 fixed to the upper rail 40 is coupled to the transfer port 96 of the bidirectional damping stopper 90, The conveying port 96 is conveyed along the inner guide groove 97 to the center thereof.

That is, the engagement groove 96b of the conveying port 96 is conveyed while being engaged with the operation member 80 fixed to the upper rail 40, and at the moment when the edge of the inner guide groove 97 is out of the inclined section, By the tension of the spring 101, the feed port 96 is conveyed to the horizontal section, and the subsequent conveyance is conveyed to a position where it is engaged with the actuating member 80 at the center.

The piston 94 connected to the piston rod 95 is compressed in the pneumatic cylinder 93 in the course of being transported by the tensile force of the tension spring 101 as described above and the pneumatic cylinder 93 The inner air is discharged through the fine holes formed at the end of the pneumatic cylinder, so that the speed is gradually damped and the damping operation is performed.

The opened or closed central door 10 is stopped at a precise position while attenuating the speed slowly to the position where the conveying port 96 of the bidirectional damping stopper 90 is engaged with the operating member 80 of the upper rail 40 .

Since the central door 10 is operated in the same manner by the above-described operation principle only when it is opened and closed to the left side, the opening and closing operations can be carried out regardless of opening or closing in any direction. It will be lost.

Accordingly, the damping system of the present invention can be suitably applied to a sliding three-door system composed of the left and right doors 20 and 30 and the central door 10, So that the damping action is completely performed, so that a safe and reliable opening and closing operation can be expected.
