Utility Model Registration No. 3212164 JP 2022-47453 A Japanese Patent Publication No. 2016-537529 JP 2015-25334 A Japanese Patent Application Laid-Open No. 2017-856

For large furniture with sliding doors, we are expecting sliding doors that operate smoothly with almost no noise of 45 dB or less when opening and closing. If the material, shape, and size of the roller for driving the door of the sliding door and the guide rail for guiding the roller are appropriately selected, a sliding door meeting the target can be obtained. For example, in the case of a heavy door, if the width of the roller is relatively wide, there is a problem of smoothness and noise in opening and closing due to the contact between the rail and the roller of the door. However, simply moving due to the structure of the rail and the material and structure of the roller, and the contact between the roller and the groove surface may damage the opposing surfaces of the sliding door and cause the inconvenience of generating noise. As a result, the appearance of the surface of the sliding door is greatly damaged, and the weight of the door causes noise when the door is opened and closed.

According to the present invention, when the sliding door of furniture having a large and heavy sliding door is operated, considerable force is required for the initial movement at the time of opening and closing, and noise is also generated. Therefore, by providing a drive mechanism consisting of two Y-shaped grooves and resin rollers, aluminum guide rails that can be opened and closed lightly and smoothly without making a sound are considerably improved in terms of materials and structure. It is very easy to remove dust accumulated in the guide part of the contact rail, and the rollers of each sliding door are provided so as to be movable relative to each other by reducing contact with the rail. To provide storage furniture having an opening/closing drive which reduces noise caused by rubbing of a rail door and does not damage the door. It would be desirable to have storage furniture provided with a drive for opening and closing large, heavy doors.

Since rails are formed inside the box and the sliding door is attached, when it is used as an open storage furniture, the vertical partition is positioned in a position that is retracted backward from the front of the box, giving it a classy look. It has the disadvantage of being damaged. On the other hand, if the front of the cabinet and the front of the vertical partition are made almost flush to ensure the dignity of open storage furniture, the sliding door rail crosspieces that show a metallic luster in the middle of the furniture as a whole look like a wooden pattern. In addition to enhancing the sense of luxury, the sliding door moves smoothly with a quiet sound and gentle movement.

The present invention has been made by paying attention to such problems, and the sliding door is light and smoothly driven by a simple structure without impairing the dignity of storage furniture with a large and heavy sliding door. To provide a novel and useful storage furniture that can be installed without difficulty, without vigorously colliding with the side plate of a storage tool body, without fear of generating noise or damaging the storage tool. It is.

In order to open and close the sliding door of storage furniture quietly, safely, and smoothly, there are two reverse concave rectangular guide rails in the upper frame of the opening for the sliding door of storage furniture, and two in the lower frame. A Y-shaped dug-shaped lower rail or a sound-reducing two-piece Y-shaped dug-shaped lower rail is attached, and a length having a damper function is attached to the upper rail body for the reverse concave rectangular parallelepiped guide. Runners with open/close two-way soft closers with dual double rollers inserted at both ends of the cuboid are inserted so as to be slidable. A base cup that can easily hang the runner and a slide roller that can be rotated on the Y-shaped dug-in lower rail are fitted to the lower crosspiece frame at two places, respectively, and can be gently driven when opening and closing. It is a piece of furniture with a sliding door that moves quietly with a quiet sound. In particular, the upper runner with a soft closer is a box-shaped cover frame that has a damper function. It eliminates horizontal and vertical vibration of the runner roller on the rail and eliminates noise. In the lower rail, the contact noise is reduced by the partial contact of the Y-shaped surface, which reduces the contact surface between the rail door and the slide roller.

The storage furniture in the sliding door is a book/decoration storage furniture and a cupboard with a width of 800 to 2400 mm, and is made of resin and aluminum as materials to prevent noise when opening and closing the door of the integrated heavy sliding door. By using it, the adhesion surface of the resin roller and aluminum rail is reduced, and two guide rails for driving the door are placed on the top and bottom of the sliding door to enable smooth driving of the roller. An aluminum rail with a convex portion is attached to the frame bars at the top and bottom of the opening of the sliding door, a resin dual double roller is inserted at both ends of the liner that runs on the aluminum rail, and the door is attached to the reeler. In a sliding door in which a base cup that can be hung is fitted to the front upper part of the door, a guide rail attached to the upper crosspiece frame of the opening and a runner drive movable in the opening and closing direction along the guide rail It is furniture with a sliding door that moves gently with a quiet sound to which a roller member is attached.

The reverse concave rectangular parallelepiped guide rail attached to the upper frame of the sliding door opening of the storage furniture is a reverse concave rectangular parallelepiped with an open bottom, and drives and guides the wheels of the resin rollers of the runners. In order to do so, a rail-shaped projection is provided at the lowest position on both sides of an inverted concave rectangular parallelepiped with one side open at the bottom, which has a width that allows insertion of a resin dual double roller, and the upper surfaces of both rail-shaped projections The dual resin rollers that are fitted to the runner are running on the runner, and the guides that can stably protect the rollers, which are shaped like train wheels, are placed at the upper positions on both sides of the inverted concave rectangular parallelepiped. A Y-shape is provided, and the resin roller has an appropriate guide interval for running on a rail similar to the shape of a train wheel, and is fitted into the lower crosspiece frame. The dug-shaped lower rail can run on guide roller bodies fitted in two places on the lower part of the door.

The runner with open/close two-way soft closer has a noise reduction damper function that reduces the noise generated by the rotating running of the resin roller on the metal rail. A rectangular cylinder holding a closer function part is used, and the fulcrum on the rail is increased at both ends of the rectangular cylinder, so that even a heavy door can generate noise due to light contact between the roller and the rail due to the distributed load. A dual resin double roller consisting of eight wheels that reduces the load is inserted, and a hook that allows the door to be easily hung is attached to the center of the resin dual double roller. there is

Each door installed as a sliding door of furniture is connected to the opening and closing drive by simply hanging the hook part of the roller center part of the runner on the upper part to the base cup of the fixture that is fitted in two places on the upper part of the door. Y-shaped excavation in which the reverse concave rectangular parallelepiped guide rail body attached to the upper crosspiece frame is connected to the running liner, and the slide roller attached to the lower part of the door is fixed to the lower crosspiece frame. It runs contactively on the lower rail and drives smoothly as a guide.

The sliding door, which moves gently with a quiet sound, is opened and closed by inserting a reverse concave rectangular parallelepiped guide rail body, two Y-shaped grooved lower rails in the lower frame, and dual double rollers. It consists of a runner with a two-way soft closer, a base cup that can be hung on the runner, and a door fitted with a slide roller. and two Y-shaped excavated lower rails are attached to the lower crosspiece frame, and then, according to the desired sliding door dimensions, it has a damper function and has a soft closer function part that operates in two directions inside. Assemble the rectangular cylindrical body, insert it into the reverse concave rectangular guide rail body of the upper rail frame, and finally hang it on the door where the base cup and slide roller are fitted to the hook part of the liner. It is composed of a sliding door that can be opened and closed quietly, safely, and smoothly.

By forming the guide rail of the door with two grooves and using an integrated guide rail made of metal for the width of the groove, the smoothness of opening and closing due to the contact between the rail and the roller of the door is increased, and the noise caused by the movement of the door is further reduced. problem is gone. Scratches the facing surfaces of the sliding door, causing the inconvenience of generating noise. As a result, the external appearance of the sliding door surface on the back side is greatly damaged, and noise is generated when the noise door opens and closes. was left. When this device is used, the driving of furniture with large and heavy sliding doors becomes quiet and gentle movement.

When a rail crosspiece is formed inside the box and a sliding door is attached to use it as storage furniture, it is located at a position retracted rearward from the front of the box, so that the dignity is not spoiled. By making the front of the furniture almost flush with the floor to secure the class as an open storage furniture, the sliding door rail crosspiece showed a metallic luster in the middle position of the furniture as a whole. In addition to enhancing the wooden pattern and bringing a sense of luxury, the sliding doors of furniture that have sliding doors that move gently with a quiet sound have become extremely quiet and light and smooth. .

In addition, there is no risk of damaging the visible surface of the sliding door, and a clearance can be secured between the sliding door positioned on the front side and the upper front edge of the opening of the main body of the storage unit. There was storage furniture that played. In addition, the left and right sliding doors can be gently slid toward closing, and the operation feeling of each sliding door when closing is uniform and has a good feeling of use, and the opening width can be increased. And it is possible to provide furniture with a top plate provided with such a storage tool. Sliding door type storage furniture can be easily and properly installed with a simple structure without impairing the dignity of a piece of furniture having a sliding door that moves gently with a quiet sound. I was able to make the opening and closing operation of the door a gentle movement with a quiet sound.
