As shown, a typical sliding door 110 is installed on the front of the furniture 100, such as a wardrobe, a built-in cabinet, a bookcase, a sink, a storage cabinet, or a bathroom cabinet, so that the stored items are not exposed to the outside. It includes an upper roller bracket 134 on which upper and lower rollers 132, which are upper and lower moving means 130, are mounted so as to be slidable on the lower rail 120B.

In the furniture of the present invention, there are many configurations that are installed to correspond to the upper part and the lower part. In contrast, the upper part and the lower part are divided by attaching A and B to the rear end for each configuration. For example, the upper rail is divided into 120A and the lower rail is 120B, the upper moving means is 130A, the lower moving means is 130B, the upper roller is 132A, and the lower roller is 132B.

The sliding door 110 may include a frame constituting an edge, and a conventional panel or mirror inside the frame frame.

In the above, one end of the roller bracket 134 of the moving means 130 is mounted on the frame or panel of the sliding door 110 in a conventional manner.

Rails for leveling and separating a sliding door including roller brackets respectively mounted with rollers movably on the upper rail 120A and the lower rail 120B provided on the upper and lower portions of the furniture 100 according to the present invention The height adjusting device of the upper rail 120A is located on the underside or front of the inner upper portion of the furniture 100 and the lower rail 120B is disposed on the inner floor or the bottom surface of the furniture 100 in a conventional manner. do.

Here, the upper rail 120A includes a mounting member 10 that is mounted and fixed to both inner sides or both sides of the front side of the furniture 100 , and is fixed after being lifted on the mounting member 10 . It is coupled with;

Both ends of the upper rail 120A are raised or lowered up and down by the elevating means 1, so that leveling for the sliding of the roller, which is a moving means, can be performed conveniently without hassle. At this time, the lower rail 120B disposed under the furniture is fixed to the furniture and does not move up and down. Accordingly, when the upper rail 120A descends, the gap between the upper rail and the lower rail is narrowed, and the roller bracket 134 coupled with the sliding door can be separated from the lower rail 120B and can be easily separated.

More specifically, if you want to separate the sliding door 110, open the sliding door, move it to either side of the furniture 100, and then lower the exposed upper rail 120A by pressing or impacting it. , the mounting member 20 inserted and coupled to both ends of the upper rail descends from the mounting member 10 . At this time, since the lower rail 120B is fixed, the roller in contact with the lower rail is separated from the lower rail while the upper rail and the lower rail are close to each other to separate the sliding door 110 . The moving means 130 mounted on the sliding door 110 is quickly and simply separated from the upper rail 120A. Before applying pressure or impact to the upper rail 120A, the mounting member 20 and the furniture 100 must release the coupling state. If the sliding door is heavy, the upper rail is lowered by pressing the mounting member 20 whose coupling state is released without additional pressure.

As described above, as the upper rail 120A is lowered, the roller bracket 134, which is the moving means 130 mounted on the upper rail, is lowered at the same time, and accordingly the sliding door is lowered together. The conventional sliding door 110 requires a predetermined space to be lifted upward for separation, but in the present invention, as the upper rail descends, the sliding door descends and a new space is created, so after the sliding door is mounted It has a great advantage that it can be separated without an upper space.

The present invention can make the separation of the sliding door quick, simple and convenient. Mounting of the sliding door can also be achieved simply by placing the moving means on the upper rail and then pressing and raising the upper rail and then fixing the mounting member 20 and the mounting member 10 .

The mounting member 10 includes a mounting piece 12 having at least two mounting holes 12A formed on both sides of the inner side or the front side of the furniture 100 by a conventional screw or the like, and the mounting piece 12 . Each of the guide pieces 14 formed by bending toward the front side at both side ends of the mounting member 20 are inserted so as to be liftable.

In the above, the guide piece 14 is formed of a vertical surface perpendicular to the mounting piece 12 and a horizontal surface bent orthogonally from the vertical surface as shown in FIG. one of the things that become

In other words, the mounting member 10 is fixed to the furniture by the mounting piece 12, and the guide piece 14 serves as a guide to move up and down without shaking while the mounting member 20 is inserted therein. do.

The holding member 20 is inserted into the insertion grooves 122 formed at both ends of the upper rail 120A, and the mounting piece 22 is mounted and detachable, and the guide piece 14 is perpendicular to the lower side from the mounting piece 22. ) is inserted between the elevating piece 25 in which one or more fastening holes 24 are formed to which at least one or more fasteners 23 such as conventional bolts or screws are fastened while elevating.

The mounting piece 22 is inserted into the insertion grooves 122 formed at both ends of the upper rail 120A. Here, when the 'insertion' of the mounting piece 22 is directly inserted into the insertion groove 122, the mounting piece 22 is inserted into the insertion groove 122 as in the case of fixing with screws or the like from the outside of the insertion groove 122. ) are combined in various ways.

The mounting piece 22 of the mounting member 20 is inserted into the insertion groove 122 of the upper rail 120A, and the upper rail 120A is moved up and down. When mounting, after pushing up to the top of the furniture 100, insert the fastener 23 into the fastening hole 24 of the elevating piece 25 to fix it with the mounting member 10, the position of the upper rail is confirmed and leveling is Of course, the height is adjustable. At this time, depending on the installation environment of the furniture, it is possible to simply adjust the height so that the rollers can be placed on the upper and lower rails without raising the upper rail to the top of the furniture.

The holding piece 22 and the lifting piece 25 are orthogonal to each other, so that the holding piece is horizontal to the ground and the lifting piece 25 is vertical to the ground. 4, by pressing the upper rail 120A in a state in which the lifting piece 25 is out of coupling with the mounting member 10 due to the separation of the fixture 23, ascending (operation for mounting the sliding door) or descending ( operation to separate the sliding door), the mounting piece 22 is engaged with the insertion groove 122 of the upper rail to rise or fall in the same manner. Leveling is performed by moving the upper rail up or down little by little.

When the sliding door 110 is raised to an appropriate position while raising the upper rail, the fixture 23 is coupled to the fastening hole 24 to prevent the lifting piece 25 from being lowered by the sliding door's own weight.

Meanwhile, the guide piece 14 may be formed on the mounting member 20 rather than the mounting member 10 . That is, the edge of the lifting piece 25 of the holding member 20 is formed in a vertical surface perpendicular to the lifting piece 25 and a horizontal surface bent orthogonally from the vertical surface, or bent from the lifting piece to a curved shape. be any one When the guide piece is formed on the lifting piece 25 , the mounting piece 12 of the mounting member 10 is inserted therein. When the guide piece is formed on the elevating piece as described above, the fixture 23 for fixing the elevating piece 25 passes through the mounting member 10 and is coupled to the furniture.

Here, the rollers 132 placed on the upper rail and the lower rail of the sliding door 110 are in contact with the upper rail from the upper side and the lower rail from the lower side. The relationship between the roller and the rail changes when the distance between the upper rail and the lower rail approaches. The upper roller 132A on the upper rail is located on the upper rail 120A as it is by its own weight, but the lower roller 132B in contact with the lower part of the lower rail 120B is spaced apart from the lower rail so that the sliding door 110 can be easily opened. It can be detached from the rail. Mounting of sliding doors is the opposite of detachment.

In the present invention, the raising and lowering of the upper rail is equal to or greater than the width at which the moving means 130 can be separated from the rail. As for the moving means, one surface of the roller bracket 134 is fixed to the sliding door, and the roller 132 provided on the other surface spans the rail, and at this time, the roller 132 rises or descends enough to escape from the rail. In particular, to the extent that the lower roller can be separated from the lower rail, the sliding door can be separated. At the time of initial installation, the roller is placed on the upper rail in a state in which the upper rail 120A is lowered, and the sliding door 110 is placed at an appropriate position of the furniture 100 by raising the upper rail, so that the width of the rise of the upper rail is increased. In the case of repair, the lowering width of the upper rail is sufficient to allow the rollers to be separated, and further lowering makes it easier to separate the rollers.

On the other hand, the present invention is possible even when the roller is disposed on the upper portion of the lower rail. At this time, when the upper rail descends and the upper rail and the lower rail approach, the lower roller 132B placed on the lower rail is positioned as it is, so that the upper roller 132A is spaced apart from the upper rail. If the upper roller is separated from the upper rail, the sliding door may fall over, so caution is required.

According to the present invention, not only leveling but also height adjustment can be conveniently performed by a mounting member mounted on furniture, which is an elevating means, and a mounting member for mounting an upper rail while ascending and descending on the mounting member.

In particular, the separation of the sliding door according to the lifting and lowering of the upper rail also provides the convenience of simple and easy separation rather than a cumbersome or complicated process. In particular, there is an effect that the sliding door can be easily separated or mounted even when there is little or no separate space on the upper part of the sliding door after the upper rail is mounted.

5 is a partially enlarged cross-sectional view for explaining a deformed state of the present invention.

As shown, in the present invention, leveling of the upper rail as well as height adjustment can be made simply and conveniently by the elevating means, and even fine adjustment can be made during leveling or height adjustment.

At this time, the mounting member 10 includes a fine adjustment unit 30 for finely adjusting the height of the mounting member 20 , wherein the fine adjustment unit 30 has a spiral height formed at the lower end of the mounting piece 12 . A support piece 32 on which the adjustment hole 32A is formed, and a height adjustment tool such as a conventional bolt or a mood bolt or a wrench bolt that is screwed to the height adjustment hole 32A and comes into contact with the lower end of the mounting member 20 (34).

In the above, the support piece may be mounted on the inner surface or the front side of the furniture in a conventional manner, and of course, it is preferably formed integrally with the lower end of the mounting piece of the mounting member.

Accordingly, in the state that the leveling and height adjustment of the upper rail are temporarily adjusted by the elevating means, the height adjuster, which is the fine adjuster, is rotated to adjust the height to the correct position and then fixed by the elevating means. conditions that can be easily achieved.

6 to 12 show a second embodiment of the present invention.

In the second embodiment, a description of the same configuration as that of the first embodiment will be omitted, and differences will be mainly described. Figure 6 is an exploded perspective view of the detachable configuration of the sliding door of the second embodiment of the present invention, Figure 7 is a state diagram in which the mounting member and the mounting member of the second embodiment of the present invention are coupled, Figure 8 is the second embodiment of the present invention It is a state diagram showing the coupling state of the detachable configuration of the sliding door as viewed from above, FIG. 9 is a state diagram showing the coupling state of the detachable configuration of the sliding door of the second embodiment from the bottom, and FIG. 10 is the upper part according to the second embodiment of the present invention.

11 and 12 show that the second embodiment is installed under the sink, and the furniture installed under the sink lacks the upper space required for attaching and detaching the sliding door. became Since the present invention does not require an upper space for attaching the sliding door, the sliding door can also be installed under the sink. The irregular part in the upper part of the drawing is the sink.

As shown in FIG. 11 , two or more sliding doors 110 are installed across the upper rail and the lower rail throughout the furniture. As in the first embodiment, the upper roller 132A is mounted on the upper part of the upper rail 120A, and the lower roller 132B is fitted on the lower part of the lower rail 120B from below, including an upper roller and a lower roller The upper and

lower roller brackets

134A and 134B are coupled to the upper and lower portions of the sliding door 110 .

In this embodiment, after the mounting member 10 is inserted into a separate pipe 50 , the pipe 50 is fixed in the vertical direction of the furniture 100 . The pipe 50 is formed with a rectangular installation groove 51 in the upper portion. The mounting member 10 is inserted into the installation groove 51 . Unlike the first embodiment, the mounting member 10 is provided with an upper piece 11 in which the upper portion of the mounting piece 12 is bent. The upper piece 11 is tightly fitted with the inside of the pipe 50 to fix the mounting member 10 so that it does not flow inside the pipe.

The mounting member 20 includes a lifting piece 25 coupled to the mounting piece 12 and a mounting piece 22 coupled to the upper rail 120A. The elevating piece 25 is formed with a fastening hole 24 fixed to the mounting piece by a fastener 23 such as a screw. A mounting hole 22A is formed in the mounting piece 22 . The mounting hole 22A is coupled by the mounting fixture 21 and the fixture 23 inserted into the insertion groove 122 of the upper rail 120A.

As shown in FIGS. 6 and 8, the mounting fixture 21 is formed separately from the mounting piece 22, and a mounting fixing groove 21A into which the fastener 23 is inserted is formed on one side. The fastening groove 21A has a screw thread formed therein and functions as a nut coupled to the screw thread formed in the fixture 23 . The mounting fixture 21 is inserted into the insertion groove 122 of the upper rail 120A and is fixed by the mounting piece 22 and the fixture 23 disposed below. Wings branched from the upper rail are provided between the mounting fixture 21 and the mounting piece 22, and when the mounting fixture 21 and the mounting piece 22 are tightened by the fastener 23, the mounting member 20 and the upper rail (120A) is strongly coupled.

When the mounting fixture 21 is inserted into the insertion groove 122 of the upper rail, the mounting piece 22 is disposed at the lower end of the upper rail, and the mounting piece 22 and the upper rail 120A are strongly coupled by the fastener, the flow is reduced. There is no vibration or noise, and the upper rail 120A on which the upper roller 132A moves does not interfere with the movement of the upper roller. Therefore, the upper roller can move smoothly and quietly on the upper rail.

The lifting piece 25 of the mounting member 20 is coupled to the mounting member 10 by the mounting piece 12 and the fixture 23 . The mounting member 10 is inserted into the open upper end of the pipe 50 and disposed in the pipe, and the mounting member 10 disposed inside the pipe has a part of the mounting piece 12 on the outside through the installation groove 51 . is exposed At this time, the entire installation hole is exposed to the outside. The fastener 23 is coupled to the mounting hole 12A formed in the mounting piece 12 exposed to the outside and is fixed to the pipe. At this time, the edge of the installation groove 51 of the pipe 50 is formed to have a stepped pipe blade 54 in the longitudinal direction to prevent the mounting member 10 from escaping from the installation groove 51 . The fixture 23 penetrates the mounting hole 12A and presses the inner wall surface of the pipe to fix the mounting member 10 .

Pipe fixing grooves 53 are formed in the upper and lower portions of the pipe 50 to fix the pipe to the furniture 100 using screws or the like.

A plurality of mounting holes are formed in the mounting piece 12 of the mounting member, and are coupled with the mounting hole 24 and the fastener 23 formed in the mounting hole and the elevating piece 25 as shown in FIG. 7 . The lifting piece 25 is preferably coupled to the mounting piece 12 in the state entered into the pipe blade 54, but may be coupled by a fixture with the pipe blade 54 interposed therebetween.

In the second embodiment, the mounting hole 22A of the mounting piece and the fastening hole 24 of the lifting piece are simply grooves. It is coupled with the male and female threads of the fixture.

In this fixed state, if the fastener 23 fixed only to the mounting piece 12 is released and the fastener is tightened at an appropriate height, the mounting member 10 is fixed inside the pipe. A pipe 50 fixed to both sides of the furniture, a mounting member 10 fixed to the inside of the pipe, a lifting piece 25 of the mounting member 20 coupled to the mounting member 10, and the lifting piece vertically bent Mounting piece 22, the upper rail 120A coupled to the mounting piece 22, the upper roller 132A placed on the upper rail 120A, the upper conveying means 130A to which the upper roller is coupled, and the upper conveying means are combined The sliding door 110 is combined with the furniture in the order of the sliding door 110 to be opened and closed.

In a state in which the sliding door installation is finished, if the sliding door needs to be separated, the mounting member 10 moves up and down in the pipe 50 by releasing the fixture that is not coupled to the lifting piece 25 as shown in FIG. 10 . can move The installation groove 51 of the pipe 50 is drilled in the longitudinal direction, and the upper end and lower end thereof become a movement limit position of the mounting member 20 protruding to the outside. That is, in the mounting member 20, the mounting piece 22 protrudes to the outside of the pipe 50, and the lifting piece 25 is coupled to the mounting piece 12 disposed inside the pipe, so the mounting member is located in the lower part of the installation groove. It cannot go down to the upper part of the installation groove and cannot go up to the upper part of the installation groove.

The lower end of the insertion groove 51 has a larger groove so that it can be inserted into the pipe 50 by descending in a state in which the lifting piece 25 is coupled. In this case, the mounting piece is caught in the insertion groove 51 and the mounting member 20 cannot be lowered any more, and the upper rail cannot be lowered any more. The operator separates the sliding door in a state in which the holder is caught at the lower end of the insertion groove and stopped, so the operation can be performed safely.

In the present invention, the movement of the upper rail 120A is sufficient as long as the upper rail descends enough to allow the roller bracket 134 of the upper rail to be separated, so that the pipe installation groove does not need to be very large. As in the first embodiment, since the width of the lowering and rising of the upper rail is greater than the extent to which the roller mounted on the rail can be separated, the vertical height of the installation groove 51 does not need to be formed very large.

The side width of the upper rail 120A is in surface contact with the insertion groove side 52, which is one end face of the pipe 50, so that the flow is reduced, so that it is stably supported without being shaken even by the sliding movement of the roller on the upper rail.

A thread is formed inside the mounting hole 12A and the fixing groove 21A of the second embodiment, and when a screw or a screw having a screw shape is introduced, the thread and the screw groove are coupled to each other to form a strong bond.

In addition, since the bent upper piece 11 of the upper portion of the mounting member 10 is coupled with the inside of the pipe 50 , it can be fixed without shaking inside the pipe 50 by coupling with the fixing member 23 . Here, since the end face of the upper rail 120A and the side surface of the installation groove 52 are in surface contact with each other, they are fixed in a double triple, thereby providing a sense of stability without shaking when the sliding door is opened and closed.

In the second embodiment, the sliding door can be separated more simply than in the first embodiment. If the fixture coupled with the mounting hole 12A of the firewood piece 12 is released directly without the intervening of the lifting piece 25 (in the present invention, the separation of the fixture means not only the complete removal but also the state in which the binding is released), mounting The member 10 is movable within the pipe 50 . The mounting member 20 presses the upper rail 120A in a state coupled to the end of the upper rail 120A (or by the weight of the sliding door), the upper rail 120A, the mounting member 20, and the mounting member 10 ) and descend at the same time. When the upper rail descends, the lower roller is separated from the lower rail. When the lifting means 1 is caught on the lower end of the installation groove 51 of the pipe 50 and the movement is stopped, the sliding door 110 is slightly raised to separate the roller from the upper rail, and the sliding door 110 is the upper rail. separated at (120A). For the repaired or replaced sliding door, the upper roller of the upper moving means coupled to one side of the sliding door is placed on the upper rail, and then the upper rail 120A is raised to insert the lower roller into the lower rail. After that, when the fixture is coupled to the mounting hole of the mounting piece to strongly bind the pipe and the mounting member, the installation of the sliding door is completed.

As described above, according to the present invention, the sliding door can be easily separated or mounted from the rail, and the sliding door can be separated or mounted from the furniture quickly and conveniently without requiring skilled workers.

In the second embodiment, even if there is no separate pressurization on the upper rail, if the fastener is rotated in the mounting hole to remove the strong binding (combination) between the mounting piece and the pipe, it will descend by the weight of the sliding door connected to the upper roller mounted on the upper rail. can In the first embodiment, since it is preferable that the upper rail is forcibly coupled to the furniture, it is possible to descend only when the upper rail is pressurized. In the second embodiment, since the coupling (coupling) between the mounting member and the pipe is removed in a state in which the mounting member and the holding member are coupled, a strong coupling between the upper rail and the pipe is not required. Accordingly, in the second embodiment, when the bond between the mounting member and the pipe is lost, the sliding door descends by its own weight even without pressure of the upper rail. When the upper rail is raised, as in the first embodiment, the second embodiment must also have upward pressure.
