The other side to the rear,

The base plate 10 coupled to the door is set to the bottom and the roller 40 is set to the top.

1 is an exploded perspective view of the roller assembly according to the present invention, FIG. 2 is an exploded perspective view of the roller assembly in which the wheel 41 of the roller 40 and various rivets and bolts are omitted, and FIG. (Side observation) and FIG. 4 (Rear observation) are combined cross sectional views of the roller assembly according to the present invention with different observation directions.

As shown in Figures 1 to 4, the roller assembly (A) according to the present invention is largely coupled to the base plate 10, the roller 40 mounted on the rail of the door frame, the base plate is coupled to the upper sliding hanger door, And a supporting bolt 20 for connecting the roller and the roller, and the support plate is coupled to the base plate to surround the supporting bolt so that the supporting bolt does not swing against the base plate even under pressure and impact applied to the door. It consists of a reinforcement bracket (30) to ensure the quietness and operation reliability.

The base plate 10 is formed in the front and rear door contact portion 15 having a fastening hole 15a for coupling with the door, and a rising portion 11 rising upward from the other portion in the center thereof, and the supporting bolt 20 Coupling portion 13 for) is formed,

The coupling part has a trim part 13A open to one side to easily couple the base plate 10 to the upper part of the door in advance, and then fasten the supporting bolt 20.

Riveting hole (11r) is formed in the coupling portion 13 is to enable rivet coupling for the first bracket (30A) constituting the reinforcing bracket (30) forming the core of the present invention.

Next, the supporting bolt 20 has a threaded portion 21, a threaded insertion portion 23, and a head 25,

The threaded portion 21 passes through the threaded hole 45a formed in the lower panel 45 of the roller 40, and each threaded hole of the wheel 41 support 43A and 43B, which forms another core of the present invention. Coupled to 43c.

The insertion portion 23 is not essential, the spiral may be formed on the entire bolt except the head,

The insert is wrapped in the sleeve 27 to ensure the height adjustment of the roller assembly (A) of the present invention.

The sleeve may be made of acetal resin, which is made of engineering plastics because it is manufactured by cationic or anionic polymerization of synthetic resins, especially formaldehyde, and has excellent electrical conductivity, mechanical properties, abrasion resistance, chemical resistance, heat resistance, and a low coefficient of friction.

The head 25 is caught by the plate 10 after the supporting bolt is positioned in the coupling portion 13 via the trim 13A of the base plate 10,

In practice, the introduction of the sleeve 27 causes the flange 27A of the sleeve to contact the base plate 10,

The head is in contact with the bottom surface of the flange 27A.

Subsequently, the reinforcing bracket 30 is coupled to the base plate and serves to surround the supporting bolt.

Various modifications are possible, but for ease of assembly, the first bracket 30A and the second bracket 30B are configured to accommodate the sleeve 27 in close contact with each other.

The first bracket (30A) is a fixing portion 33 is formed with a riveting hole (33r) for coupling with the base plate 10,

An outer circumferential surface of the supporting bolt 20, more precisely, has a contact support part 31 which surrounds a part (half) of the outer circumferential surface of the sleeve 27 and is formed with a screw hole 31a.

In addition, the second bracket (30B) has a screw hole (37a) corresponding to the screw hole (31a) for coupling with the first bracket fastening portion 37 is mutually coupled by the bolt (B) and

The supporting bolt outer circumferential surface, more precisely, has a cover portion 35 surrounding the other half of the sleeve 27.

If necessary, the second bracket may have the same structure as the first bracket.

If the second bracket further has a contact support coupled to the base plate, the supporting force for the supporting bolt 20 will be improved.

Since the fastening means (bolt) to go through the process of loosening and tightening, disassembly and assembly process for the initial assembly and maintenance is slow.

The support bolt 20 is coupled to the two height adjustment nuts located between the reinforcing bracket 30 and the roller 40, in particular the lower panel 45

The upper nut 29A is in close contact with the lower panel 45 and relative to the screw hole 45a of the lower panel so that the height of the roller 40 is adjusted with respect to the supporting bolt 20. ) Is firmly fixed so that

The lower nut 29B is in close contact with the bracket 30 so that the bolt head 25 is pulled upward to press the sleeve flange 27A, and the flange presses and supports the lower surface of the engaging portion 13 of the base plate. A bolt is securely fixed between the base plate 10 and the bracket 30.

To this end, the height of the sleeve 27 except for the flange 27A should be equal to the height from the bottom surface of the base plate coupling portion 13 to the top surface of the reinforcement plaque 30.

Roller 40 which forms another core in the roller assembly (A) according to the present invention comprises a plurality of wheels (41),

First and second supports 43A and 43B each having a side portion 43a to which the wheel is fixed, a lower surface portion 43b bent at the side portion, and

It is coupled to each lower surface of the support overlapping each other, and comprises a lower panel 45 having a screw hole (45a) for the supporting bolt.

The front of the lower panel 45 is coupled to the stopper 47 in contact with the structure of both ends of the upper rail of the frame when the roller assembly (A) is mounted on the door and opened and closed.

The roller assembly (A) of the present invention is introduced at least two to one door,

The roller 40 is provided with four symmetrical wheels 41 on the roller 40 for the stable sliding of the door. For this purpose, the frame has two symmetrical rails as shown in Design Registration 0250736 or Utility Model Registration 0287697. Is introduced.

If necessary, the wheel 41 may be modified in a form in which only one pair or three or more pairs are provided.

The key point that the roller 40 is distinguished from the conventional roller is that the turning side 41a (see FIG. 1) is provided by riveting (another method of fixing) on the side surfaces 43a of the supports 43A and 43B, respectively. Combined to secure the wheel 41 (preferably a structure with bearings introduced for superior rolling performance)

Each support 43A, 43B has a form in which the lower portion 43b overlaps, and is fastened to the lower panel 45, in particular, by riveting through each riveting hole 43r, 45r. Can be significantly improved.

This can be confirmed in the rollers presented in Utility Model Registration No. 0287697 as compared to the form in which the shafts of each pair of wheels are connected to each other in a structure that is connected to the frame, its excellent productivity.

Although it is not clear from Design Registration No. 0250736, each pair of wheels is fixed to an individual frame, and then the frame overlaps and looks similar to the riveted structure.

Since a pair of wheels should be spaced at regular intervals for stable sliding of the door, the registration design has a structure in which the wheel shaft protrudes outward.

As the load is applied to the shaft, the model cannot be used when the door weight is large,

In the present invention, the protrusions of the wheel 41 and the pivoting side 41a toward the outside of the respective supports are slight, but it can be seen that the gap between the paired wheels naturally opens up the structure of a completely different concept.

Each support 43A, 43B in the roller 40 has a screw hole 43c for coupling the threaded portion 21 of the supporting bolt 20 to the center, as mentioned above.

In addition, the side portion 43a of each support has a curved portion 43a 'corresponding to the wheel shape (smaller than the wheel to prevent interference) at the portion where the wheel 41 is coupled,

In pursuit of a little beauty with weight loss function,

In addition, the automated riveting process of the wheel has a function of facilitating the clearance of the wheel due to the structure of the opening between the curved portion and the curved portion.

On the other hand, on both sides of the lower panel 45, the restraining protrusion 45b is formed in contact with each support 43A, 43B,

The restraining protrusion is easy to arrange in place and riveting during assembly of the support and the lower panel, can contribute to the improvement of the rigidity of the coupling state,

It also functions as a reinforcement to cope with loads acting in the vertical direction, such as H beams.

Since the wheels 41 should have the same height, the height of the side portions 43a of the lower second support 43B

Even if the upper first support 43A is mounted, the height of the lower surface of the upper first support must be higher than the height of the side of the upper support.

In addition, an upper panel (not shown) may be further introduced on the upper first support to help strengthen the bonding strength of the entire roller including the lower panel.

In the above description of the present invention, the roller assembly having a specific shape and structure has been described with reference to the accompanying drawings, but the present invention can be variously modified and changed by those skilled in the art, and such modifications and changes are the scope of protection of the present invention. Should be interpreted as belonging to.

The present invention provides a more complete anti-shake function by increasing the resistance against the load and impact applied to the supporting bolt through the reinforcing bracket to greatly improve the quietness and the operation reliability,

Rollers for various sliding hanger doors used in building doors, furniture doors, various electronic equipment, vehicles, etc. by improving the workability by introducing sleeves that cover the base plate trim or supporting bolts for assembling or height adjustment. By providing the assembly, it is expected to create new demand by resolving the complaints of workers and consumers.

In addition, since the productivity of the roller itself is increased through the support for the wheel composed of the first support and the second support, which are easy to install by the worker but have few parts in the production stage and overlap each other in the lower part, it can contribute to economic efficiency by reducing the production cost. Can be.
