Roller assembly of sliding door for furniture

The present invention relates to a roller assembly for guiding the opening and closing operation of a sliding door that opens and closes in a sliding manner in a furniture such as a cabinet.

In general, doors of furniture such as cabinets that are widely used in homes are usually assembled by a hinge installed in the cabinet, and the opening and closing method of opening and closing the door forward.

Since the door of the opening type is used to open in the front occupies a certain space in the front, there is a disadvantage that is very vulnerable in terms of space utilization in the room.

In addition, the case of the door of the case is difficult to apply a heavy metal door because it is assembled in a structure supported by a hinge that is vulnerable to the load, this is a disadvantage that has a limitation in applying a variety of doors to furniture There is this.

In recent years, the sliding door that opens and closes the door in a sliding manner has been used to improve the disadvantage of the door of the swing type.

Such sliding doors are opened or closed by pushing or pulling in one direction. A roller assembly is installed on the upper and lower portions of the door, and rails are provided on the upper and lower surfaces of the cabinet to guide the movement of the upper and lower roller assemblies. To open or close by pushing or pulling in one direction.

In addition, the roller assembly for guiding the opening and closing operation of the sliding door includes a means for adjusting the height of the door, a means for holding the position of the door, a means for preventing the crossover between the indoor language and the outdoor, and preventing the door from being detached. Giving means and the like are provided, so that the user can achieve convenience of operation, ease of handling, and the like in connection with opening and closing of the door.

In addition, the furniture adopting the sliding door is provided with a stopper means for mitigating the impact when the door is closed, so that the closing operation of the door can be made more smoothly.

However, the roller assembly of the conventional sliding door for furniture has several disadvantages as follows.

First, when the auxiliary bracket is rotated due to the height adjustment because the brace fixed to the rail side stopper is installed on the auxiliary bracket, the height of the brace may change, so that the claw can be lowered to the rail side, and eventually the brace is attached to the rail surface. There is a disadvantage of preventing the smooth opening and closing of the door while touching, and also has a disadvantage that the locking force is reduced while being spaced apart from the stopper side due to the height change of the latch.

Second, since the operation form between the adjustment bolt for adjusting the height of the door and the auxiliary bracket is made of a rotating structure using an inclined surface, the operation is not easy and the height adjustment state is not stable.

Third, the rubber part installed in the in-door roller assembly for preventing the crossover has a disadvantage in that the opening distance of the outdoor door is limited in preventing the crossover with the outdoor because it is installed at the position overlapped with the roller. In the case of the cross-prevention means, the cross-prevention means also does not perform 100% due to the change in height due to the rotation of the auxiliary bracket when the height adjustment is installed on the auxiliary bracket.

Fourth, in the case of safety pins installed on the inside roller assembly to prevent the doors from coming off, there is no means to hold them, so the safety pins may be released due to the shock when the stopper stops. Has a high disadvantage.

As shown in FIG. 1, a sliding door installed in a furniture such as a chest of drawers or a chest of drawers is installed with a roller assembly for guiding opening and closing of the door while moving along the furniture side rail, and the sliding door is provided at both ends of the furniture side rail. A known stopper (not shown) is intended to stop at a fixed position (closed position or open position).

The roller assembly provided in the present invention is applied to both the outdoor door and the inside door which is installed on the outer rail while being installed on the inner rail of the furniture body.

Here, the roller assembly is supported on the front of the main bracket 10 having a main bracket 10 having a structure fixed to the inner surface of the door body of each door by screws or the like, and a roller 12 moving on a rail. It includes an auxiliary bracket 11, and mainly serves to guide the opening and closing operation while supporting the upper end of the door.

In addition, the lower end of the in-door or the outer door is equipped with a known bracket and roller combination structure, and thus the opening and closing operations of the door can be balanced and guided from the top and bottom together with the roller assembly of the upper end. The description will be omitted.

In particular, the roller assembly for the outdoor is provided with a latch (15) to be held on the rail side upper stopper (not shown) to maintain the locked state of the outdoor, the latch (15) at this time as the auxiliary bracket 11 It is installed on the main bracket 10, rather than the structure that the position is variable when the height is adjusted to maintain the fixed position regardless of this even if the auxiliary bracket 11 is moved by height adjustment. .

To this end, one side of the main bracket 10, for example, one side of the rear end of the main bracket 10 in which the adjustment bolt 13, which will be described later, is installed, is fixed with a vertical posture clamp 15. The latch 15 is positioned in such a way as to extend down a predetermined length from the bottom of the rear end portion of the main bracket, and when the door is closed, the latch 15 is engaged with the upper stopper installed on the rail side to maintain the closed state of the door.

As the latch 15 is installed on the main bracket 10, even when the entire auxiliary bracket 11 including the roller 12 is moved when the door height is adjusted, the latch 15 is not affected by the latch 15. ) Can always be kept in a fixed position, so that the problem of impairing the opening and closing performance of the door due to the interference of contact with the rail side can be solved recently, and the precise positional relationship with the upper stopper on the rail side It can be maintained at all times to solve the problem of lowering the locking force.

In addition, the present invention provides a newly improved height adjustment device for adjusting the height while moving the entire auxiliary bracket 11 including the roller 12 in the front and rear slide structure instead of the rotating structure.

To this end, an auxiliary bracket 11 having a roller 12 is installed side by side on the front side of the main bracket 10 fixed to the door side, and on the rear end of the main bracket 10 on the bolt bracket 26. The adjusting bolt 13 is provided to be screwed in a horizontally penetrating form.

In addition, the auxiliary bracket 11 is also formed in the main bracket 10 through at least one or more slots 16, for example, three slots 16 arranged in a triangular shape. At the rear end of the auxiliary bracket 11, which is inserted into the two pins 17 and which is fluidly supported, and which is adjacent to the front end of the adjusting bolt 13; ) Is integrally formed.

Accordingly, when the user tightens or loosens the adjustment bolt 13 to adjust the height of the door, the contact piece 18 contacting the front end of the adjustment bolt 13 is pushed or the contact piece is reversed by the door weight. 18) comes into close contact with the tip end side of the adjusting bolt 13, and as a result, the entire auxiliary bracket 11 including the roller 12 moves in an oblique direction according to the operation of the adjusting bolt 13, so that the height of the door is adjusted. It becomes possible.

The height of the door can be adjusted by the height change of the roller 12.

In addition, the adjustment bolt 13, as shown in Figure 6, the urethane coating layer 19 is formed on the screw portion, thereby being able to prevent the bolt from coming off due to the thread clearance, the adjustment bolt ( 13), that is, the stable position can be secured.

That is, since the urethane layer having a predetermined thickness coated on the screw portion of the adjusting bolt 13 fills the gap between the bolt bracket side thread and the adjusting bolt side thread, the fastening state of the adjusting bolt 13 can be stably maintained. And, after adjusting the fastening position of the adjustment bolt 13, it is possible to fix the adjusted position at this time more stably.

Figure 2 is a perspective view of the roller assembly for the door according to an embodiment of the present invention.

As shown in Figure 2, here shows a means that can prevent the intersection between the in-door and the out-door when opening and closing the door, that is, the cross-block 20.

On the front of the main bracket 10 to be installed in the main body of the in-door is provided with an auxiliary bracket 11 which is supported by a structure that is movable by the pin 17 and the slot 16, the front of the auxiliary bracket 11 The roller 12 of the rotatable structure is installed, and the cross-preventing device 20 is installed at a predetermined distance away from the rear side of the roller 12 installed in this way.

In particular, the cross-preventing device 20 is installed at a position spaced apart from the rear of the roller 12 by a predetermined distance, it is possible to ensure a wide range of the intersection with each other between the inner door and the outer door.

That is, in the past, the cross stop 20 is installed in the position overlapping the front of the roller 12 or the roller 12, there was a limit on the open distance of the outdoor when preventing the cross, but in the case of the present invention cross By installing the prevention tool 20 at a rearward distance of the roller 12 by a predetermined distance, for example, the roller 12 is installed directly under the adjustment bolt 13 provided at the rear end of the main bracket 10. By securing a constant distance between and, it is possible to increase the open distance of the outdoor door by the secured distance at this time.

In other words, as shown in FIG. 8, when the latch 15 progresses in the direction of the arrow and hits the rubber part 20b, the latch (not shown) is positioned at the position of the roller 100 in the past. The rubber part 120 of the cross-preventing device 110 is stopped, and in the case of the present invention, since the latch 15 stops at the rear side after passing the roller 12 for a while, that is, the distance is further advanced by "L". Since it stops later, it is possible to secure a section in which the two doors can cross each other as long as possible, and as a result, the opening space of the door can be increased.

In addition, in the case of the cross-preventing device 20, since it is fixedly installed on the main bracket 10, even if the auxiliary bracket 11 is moved for height adjustment, it can always be fixed at a constant position without changing the height, and eventually the outdoor While preventing the fear of crossing over the cross-preventing device 20, it is possible to always perform the correct function in place.

The cross-preventing device 20 has a plate-shaped body portion 20a vertically installed on the front surface of the main bracket 10, and the rubber portion 20b toward the roller traveling direction at the end of the body portion 20a.
