Description

Cabinet{STORAGE}

In the present invention, in a storage cabinet having both sides of the door that is opened and closed in a sliding manner, an outdoor with a long distance between the door and the roller is stably supported to prevent damage to the bracket or the fall of the door due to the load of the door, and It relates to a storage cabinet in which opening and closing is easy and both doors can be closed so that a height difference is not formed.

In general, a storage cabinet installed in a bathroom is configured such that a flat plate frame is cut into a predetermined dimension, and a partition is installed in the interior space to store a toilet bowl, towels, tissue paper, and the like.

Such a storage cabinet is installed with a door for concealing the interior on the front side in a variety of opening structures, and is generally divided into an opening-type cabinet and a sliding-type cabinet according to the opening and closing method of the door.

Double sliding cabinets are preferred to install sliding cabinets in bathrooms because there is no need to secure separate front, rear, left and right spaces required for door opening and closing.

The prior art related to the storage cabinet having such a sliding door is shown in FIG. 1A (hereinafter, reference numerals in FIGS. 1A and 1B for describing the prior art are mutually irrelevant to the reference numerals in FIGS. 2A to 5 for explaining the present invention. As shown in ), the storage space is opened and closed through a pair of sliding doors 19 in a state in which several floors are partitioned through a partition 11 in the storage space in which objects are stored.

The conventional cabinet is mainly manufactured in a form in which a mirror is attached to the front of the door,

In this form of manufacture, since the weight of the sliding door is significant, in order to stably open and close the door, there is a need for a structure in which a roller bracket provided with a roller moving along a rail is firmly coupled to the door.

That is, as shown in Fig. 1b, in order for the roller bracket 17 to be stably coupled to the door 19, the coupling portion of the roller bracket is coupled to the inner side of the door in a structure that is in close contact with the door 19. Typically, in the case of a sliding cabinet Since the inner door and the outdoor are installed on different rails, the width that protrudes from the wall on which the storage cabinet is installed is bound to be as wide as the separation width of both doors and the width of the rails separated back and forth.

In particular, in the conventional storage cabinet structure shown in FIGS. 1A and 1B, the rollers and rails supporting the load of the outdoor are inevitably provided at the rear end of the cabinet due to the opening and closing structure with the inner door, so that the distance between the rollers and the outdoor is reduced. As the roller bracket is widened, there is a very high risk of safety accidents such as the door sagging downward because the roller bracket cannot firmly support the load of the door, the roller bracket is damaged by the load, or the door is damaged by the roller easily detached. .

For reference, as a related art, there is a registered patent No. 10-1594141.

Accordingly, the present invention was devised to solve the above problems,

Both doors can be safely opened and closed without being affected by the load of each door, and when the door is closed, both doors do not form a height difference. In particular, a ball caster is installed in the outdoor where the load of the door is relatively large. Thus, it is an object of the present invention to provide a storage cabinet capable of preventing sagging or falling of a door while smoothing the movement of the outdoor front and rear, left and right.

In order to achieve the above object, the storage cabinet according to the present invention,

The rail includes a rail portion formed in a left and right longitudinal direction from a front end side of the first rail groove,

It characterized in that it comprises a; and a second bracket mounted on the rear side of the other side indoor, a second roller assembly provided on the second bracket and having a vertical roller or a ball caster that is supported and slid by the rail.

The cabinet according to the present invention,

By installing a ball caster in the outdoor where the load of the door is large, the outdoor can be opened and closed along the rail groove of the upper rail, thereby preventing safety accidents such as sagging or separation of the door due to the load on the door.

As the ball caster is configured to be movable between the first and second rail grooves of the upper rail, it can be closed without a step in protruding height between the two doors,

A movement preventing jaw provided on the bottom surface of the communication part connecting the first and second rail grooves prevents the closed outdoor from moving forward and protruding,

By supporting the space between the outdoor and the indoor with a support member, there is an effect of preventing the outdoor from being tilted forward by a load and being pulled toward the rear indoor side.

In the detailed description of the invention and in the claims related to other drawings, unless otherwise specified, directions are specified and described in accordance with this standard.

Hereinafter, a storage cabinet according to the present invention will be described with reference to the accompanying drawings.

As shown in FIGS. 2A to 4, the cabinet according to the present invention is large, a main body 10 capable of storing an article, both doors OD (ID) for opening and closing the main body 10, and the main body 10 Rails provided on the upper and lower portions of the (or forming upper and lower plates), and a roller assembly for slidingly coupling each door OD (ID) to the upper and lower rails 20 and 30.

The main body 10 has a storage space 11 with an open front, and a storage space 11 is formed of a flat top plate and a lower plate, both side plates, and a rear plate, and includes the storage space 11 inside. Partitions for partitioning are installed.

At this time, the upper and lower plates of the main body 10 may be replaced with the upper and lower rails 20 and 30.

That is, the upper and lower rails 20 and 30 may be coupled to separate upper and lower plates, respectively,

Alternatively, the upper and lower rails 20 and 30 themselves may be used as upper and lower plates of the storage space 11 without separate upper and lower plates.

The two doors OD (ID) open and close the front opening of the main body 10 in a sliding manner, and may be divided into an outdoor (OD) and an indoor (ID) according to a moving position, and the outdoor ( The OD) and the indoor (ID) may have a plate shape, or may be composed of a front plate in which upper, lower, left and right frames are combined in a square shape and coupled to the frame frame, and in particular, a mirror is attached.

The rail guides the left and right movement of the outdoor (OD) and the indoor (ID), and is divided into an upper rail 20 and a lower rail 30 provided at the upper and lower portions of the main body 10, respectively (upper, The lower rails 20 and 30 may be used as the upper and lower plates themselves.)

The upper rail 20 includes a first rail groove 22A formed in the left and right longitudinal direction.

In addition, the upper rail 20,

A communication part 23 that is connected to the rear from the middle part of the first rail groove 22A and one end part to guide the forward and backward movement of the ball caster 52,

It is formed in the left and right longitudinal direction at the rear end of the first rail groove 22A and is connected to the first rail groove 22A through the communication part 23, and when the outdoor is closed, the ball caster 52 ) Includes a second rail groove (22B) is stopped.

Specifically, the upper rail 20,

A rail part 21 formed along the longitudinal direction at the front end, a first rail groove 22A at the front end side and a second rail at the rear end side formed in the longitudinal direction at the rear end side of the rail unit 21 and arranged at a predetermined distance from the front and back A groove 22B, and a communication portion 23 communicating between the middle portion of the rail grooves 22A and 22B and one end portion thereof are provided.

The lower rail 30 is configured in a symmetrical shape with the upper rail 20 so that both doors OD (ID) can move with the same roller structure. It is preferable that a horizontal roller is mounted, and accordingly, it is sufficient if the outdoor (OD) has a rail groove in a form capable of moving back and forth in a closed position, and its configuration is not limited. The configuration of the lower rail and horizontal roller disclosed in 10-2019-0098276 can be used.

Again, the upper rail 20 includes a guide protrusion 21a protruding from the bottom surface of the rail part 21 in the longitudinal direction.

In addition, the first and second rail grooves 22A and 22B have the same width and length, and when the outdoor OD is opened and closed, the ball caster 52 of the outdoor OD is It moves left and right along the rail groove (22A), and when the outdoor (OD) is closed or started to open, the ball caster 52 moves back and forth through the communication part 23 so that the outdoor (OD) appears back and forth. Became,

The outdoor (OD) is opened and closed in a state protruding forward than the indoor (ID), and when the outdoor (OD) is closed, the outdoor (OD) is accommodated in the same position as the indoor (ID) and both doors (OD) are closed. ) There is no difference in height protruding to the front between the (IDs).

Specifically, first, the upper rail 20 is divided into a partition wall 22a between the moving paths of the first and second rail grooves 22A and 22B, so that the ball caster 52 during the left and right movement of the outdoor OD. ) Is formed so as not to pass to other rail grooves, and the ball caster 52 moves back and forth through the communication part 23 only in the closed position of the outdoor (OD) so that the outdoor (OD) appears back and forth.

At this time, the partition wall 22a may have a protrusion shape protruding between the completely spaced first and second rail grooves 22A and 22B, but the first and second rail grooves 22A and 22B as shown in FIG. It is more preferable that a part of) is formed as a protrusion formed while overlapping each other.

That is, the first and second rail grooves 22A and 22B are completely separated and do not have a semi-circular cross section, and part of the circumferential surfaces of the first and second rail grooves 22A and 22B overlap each other. It is more preferable to minimize the distance between the first and second rail grooves 22A and 22B having an arc-shaped cross section.

In addition, the upper rail 20 protrudes from the bottom surface of the communication part 23, but when the outdoor (OD) is pressed back and forth, the ball member 52a of the ball caster 52 has a height at which the ball member 52a can ride. It includes a movement preventing jaw (23a) protruding to have.

The movement preventing jaw (23a) allows the ball caster 52 to pass through the movement preventing jaw (23a) only when an external force of a predetermined pressure or more is applied in the front-rear direction, and in other situations, the ball caster 52 is the first rail groove. It moves left and right along (22A), or stops at the second rail groove (22B) so that it does not move.

Here, the meaning that the ball caster 52 stops and does not move in the second rail groove 22B means that on a general sliding door structure, in particular, in a structure in which the outdoor (OD) protrudes back and forth as in the present invention, the ball caster ( Including that when 52) moves to the second rail groove 22B, the outdoor (OD) and the indoor (ID) come into contact with each other so that the left and right movement of the outdoor (OD) is naturally restricted, and the second rail groove ( It should be understood as encompassing the embodiment of adding a separate stopper on the movement path of 22B).

In this case, it is preferable that the movement preventing protrusion 23a is not a separate protruding structure, but a part of the partition wall 22a is removed to protrude to a height lower than the partition wall 22a.

In particular, it is more preferable that the movement preventing jaw 23a is formed by cutting a part of the front end of the partition wall 22a in an oblique shape.

In addition, the first and second rail grooves 22A and 22B have an arc-shaped cross section of a depth surrounding a part of the outer peripheral surface of the lower end of the ball caster 52 and the ball member 52a, and the first and second rail grooves ( Before and after 22A) (22B), guide walls (22b) (22c) that close the front and rear surfaces of the ball casters (52) housing (52b) to prevent the back and forth flow of the ball casters (52) during left and right movement It is desirable to protrude.

In addition, the cross section of the movement preventing jaw 23a is characterized in that it has a triangular or similar triangular shape.

That is, a triangular or similar triangular shape formed to be inclined upward by a predetermined height (approximately 1 mm) from the first and second rail grooves 22A and 22B having an arc-shaped cross section toward the center of the bottom of the communication part 23 ( For example, it has a triangular shape, one hypotenuse is straight, and the other hypotenuse is concavely connected to the lower side in a streamlined manner, etc.).

When the ball caster 52 of the outdoor (OD) is stopped on the second rail groove 22B, the movement preventing jaw 23a is formed on the lower side of the outer peripheral surface of the ball member 52a. While being pinched in a wedge shape, the ball member 52a has a function of preventing the ball member 52a from rotating forward (an effect similar to that of pinching a crushed tree in the wheel of a vehicle), and at this time, due to the low inclination and height of the movement preventing jaw 23a, Only when the outdoor (OD) is pushed or pulled with the above pressure, the ball member 52a can ride over the movement preventing jaw 23a.

In addition, although not shown in the drawing, the first and second rail grooves 22A and 22B may be separated and formed into a pair of grooves separated from each other on the left and right based on the communication part 23 located at the middle part. Further, it may be configured as a separate groove made of three or more, which may be changed according to the number and position of the ball casters 52 mounted on the outdoor (OD).

Subsequently, the roller assembly enables sliding opening and closing of each door OD (ID) by connecting each door OD (ID) and the upper and lower rails 20 and 30 in a sliding coupling structure, It may be divided into upper first and second roller assemblies 40 and 50 and lower third and fourth roller assemblies (not shown).

In the case of the lower third and fourth roller assemblies, it is mounted on the lower rear side of each door OD (ID), and as described above, a bar that can be variously modified according to the front and rear protruding structure of the outdoor (OD). , Since there is little relevance to the core of the present invention, detailed descriptions are omitted for convenience of understanding.

Next, the upper first roller assembly 50 and the second roller assembly 40, which may be the core of the present invention, will be described.

First, the first roller assembly 50 is slidably coupled to the first bracket 51 mounted on the rear top of the outdoor OD, and supported by the first rail groove 22A from the first bracket 51. It includes a ball caster 42 that is provided with a ball member 52a that freely rotates in the front and rear, left and right directions to move to the rear side of the first rail groove 22A when the outdoor OD is closed.

At this time, the ball caster 52 moves left and right along the first rail groove 22A, passes the communication part 23 at the closed position of the outdoor (OD), and passes the first rail groove 22A and the second rail It can move between the grooves 22B, and when the outdoor OD is closed, the ball caster 52 is stopped on the second rail groove 22B.

The first bracket 51 includes a first mounting portion 51a coupled to the rear of the upper frame of the outdoor OD, and a first connecting portion 51b bent from the upper end to the rear end of the first mounting portion 51a. ,

A ball caster 52 coupled in a lower vertical direction from the rear end of the first connection part 51b is provided.

The ball caster 52 is coupled to and fixed to the lower surface of the first connection part 51b and has a lower exposed hole 52b, and is embedded in the housing 52b so that a lower part of the ball caster 52 is exposed through the exposed hole, and the housing 52b ) Is composed of a ball member (52a) that is coupled to be freely rotatable in the front and rear left and right directions.

Although not shown in the drawing, the ball caster 52 may include a bearing for rolling support for a part of the upper end of the ball member 52a in the housing 52b.

This ball caster 52 enables the left and right movement (opening and closing) of the outdoor OD while the ball member 52a rotates left and right along the first rail groove 22A, and at the same time, the communication part 23 The ball member (52a) moves back and forth at the front and rear positions of the outdoor unit (OD) so that it appears back and forth from the front of the main body,

At this time, the outdoor (OD) is supported only by the upper ball caster 52 so that the center of gravity is tilted downward and can be tilted forward (that is, the lower end of the outdoor (OD) can be tilted rearward), the outdoor of the present invention (OD) is supported by the lower roller assembly to prevent front and rear inclination, and the outdoor (OD) is supported on the front of the indoor (ID) by a support member (B) to be described later. Does not cause tilting.

Next, the second roller assembly 40 is provided on the second bracket 41 mounted on the rear upper end of the indoor ID, the second bracket 41 and supported by the rail part 21 to slide and move. Equipped with vertical rollers or ball casters.

At this time, the second roller assembly 40 may be equipped with a ball caster like the first roller assembly 50, but in the case of the indoor ID, only the left and right openings and closings are made, but not the forward and backward protruding structure. 2 The roller assembly 40 is more preferably provided with a vertical roller 42 that is built to be vertically erected at the rear end of the second bracket 41 and moves left and right along the rail part 21. Do.

The second bracket 41 includes a second mounting portion 41a coupled to the rear of the upper frame of the indoor ID, a second connecting portion 41b bent from the upper end of the second mounting portion 41a to the rear, and the second Consists of a shaft extension part (41c) bent downward from the rear end of the connection part (41b),

This second bracket 41 is slidingly coupled so that the vertical roller 42 is supported by the rail part 21, in particular, the guide protrusion 21a, and when the indoor ID is pushed left and right, the vertical roller 42 The door is opened and closed while rotating along the guide protrusion 21a.

Further, both doors (OD) (ID) are made of inclined portions (S1) (S2) that allow the inner end adjacent to the other door to contact in the diagonal direction.

That is, the inclined portions S1 and S2 of each door OD (ID) are connected to be inclined upwardly from the rear to the front toward the end.

In addition, a support member B supported on a contact surface of another door is provided on the rear surface of the outdoor OD or the front surface of the indoor ID or both.

There is no limit to the position or number of the support members (B), but in order to prevent the occurrence of inclination during opening and closing of the outdoor (OD) and the occurrence of scratches with the indoor (ID), at least two support members (B) are used for outdoor (OD). It is preferable to be provided at both corners of the lower rear side of the ), and more preferably, three or more support members (B) may be provided along the lowermost end of the outdoor (OD).

The support member (B) suffices as long as it is of a form capable of reducing friction between members facing each other while spacing two members, such as a ball bearing and a roller-type bearing, at a predetermined interval or more, and there is no limitation on the type thereof.

And when both doors (OD) (ID) are both closed and the indoor (ID) is pushed to one side, the second inclined portion (S1) pushes the first inclined portion (S2) forward and the ball caster 52 communicates with each other. The outdoor (OD) is drawn forward by riding the separation prevention jaw (23a) of the part (23) to the first rail groove (22A), and the indoor (ID) is left and right between the main body (10) and the outdoor (OD). A space that can be moved to is secured, and thus the left and right of the indoor ID can be opened and closed through this secured space.

In addition, when the outdoor (OD) is pushed to the other side while both doors (OD) (ID) are closed, the first inclined portion (S2) is pushed forward by riding the second inclined portion (S1) and the ball caster 52 ) Is passed to the first rail groove (22A) by riding the separation protrusion (23a) of the communication part (23), and the outdoor (OD) is withdrawn to the front, so in this state, the outdoor (OD) of the indoor (ID) It is possible to move left and right on the front part, so that left and right opening and closing of the outdoor OD is possible.

At this time, if the indoor (ID) or outdoor (OD) is opened and then stopped in the closed position, the outdoor (OD) is maintained in a forward-drawn state.After the door (OD) (ID) is closed, the outdoor ( When the OD) is pushed to the rear side, the ball caster 52 on the first rail groove 22A is pushed to the rear end side and passes over the separation prevention jaw 23a and stops on the stop of the second rail groove 22B,

Accordingly, the outdoor (OD) is introduced into the rear body 10 side, so that the front surfaces of the two doors (OD) (ID) do not have a height difference from each other.

In addition, when the outdoor (OD) is moved to the closed position, the outdoor (OD) does not move back and forth and is stopped at the current position unless an additional external force is applied due to the tree function of the departure prevention jaw (23a). Since the state is maintained, not only does not interfere with the left and right opening and closing of the indoor ID, it is also possible to prevent the outdoor OD from being unintentionally drawn forward and into an open state.

On the other hand, although not shown in the drawing, if magnets of different polarities are embedded in each inclined portion (S1) (S2), when each door (OD) (ID) is opened and then closed again, the outdoor (OD) can be automatically closed while being pushed toward the rear body 10 side.

In addition, as described above, the upper and lower rails 20 and 30 can replace the upper and lower plates of the main body, and the assembly of the main body 10 is improved and the upper and lower rails 20 and 30 are In order to ensure ease of manufacture, the present invention is configured by dividing the upper and lower rails 20 and 30 into two powders.
