Description

[Technical Field]

[0001] To provide a furniture sliding door with a new function that maximizes storage space, facilitates storage operation, and allows the sliding door to be opened and closed quietly and safely by providing recessed U-shaped handles on both ends of the door frame, allowing the handles to be freely operated manually on both ends of the door. [Background technology]

[0002] Conventionally, storage furniture that allows items to be stored by opening and closing sliding doors in the left-right direction typically has two doors. While these two doors can adequately access items when stacked, they often present difficulties and limit the full storage capacity. Furthermore, since one door cannot be used in either direction, storage operations are often tedious. Furthermore, the sliding of the doors on the upper and lower rails of storage furniture generates frictional noise. Attempts are being made to improve the sliding doors of such storage furniture. In particular, consideration is being given to the shape of the opening located at the front, the two horizontal rails, the weight of each sliding door, and effective handles.

[0003] As furniture with low-noise driven sliding doors that can open and close two sliding doors quietly, safely, and smoothly, and that have a smooth and easy feel when opening and closing, a sliding door has been proposed that has two inverted concave rectangular guide rails attached to the upper sash of the sliding door opening of storage furniture, and two Y-shaped recessed lower rails or two integrated Y-shaped recessed lower rails attached to the lower sash, and has an inverted concave rectangular guide upper rail covered by a box-shaped cover frame with damper function, and has a runner with a two-way soft closer that has dual double rollers inserted into both ends of the rectangular body, allowing it to slide (see Patent Document 1).

[0004] A sliding door that can move between a fully open position where the door panels are almost overlapping and a fully closed position where this overlap is almost eliminated, in which first to third parallel door panels are connected to each other via a link mechanism so that they move in conjunction with each other, and that can move between the fully open position where the door panels are almost overlapping and the fully closed position where this overlap is almost eliminated, has been reported, in which the link mechanism comprises a first link member whose base end is pivoted to the rear surface of the first door panel, a movable shaft member that is movable within a rail provided behind the second door panel and to which the rotating end of the first link member is connected, and a second link member whose one end is connected to the movable shaft member and whose other end is pivoted to the rear surface of the third door panel (see Patent Document 2).

[0005] A sliding door that is installed in an opening and has multiple door panels has been proposed that has increased rigidity against pulling or pushing forces that separate the door panels in the thickness direction, and makes it less likely for the door panels to be removed by the pulling or pushing forces. The sliding door is equipped with multiple door panels that are installed at the opening edge of a storage furniture that serves as the opening, and is configured to be movable between a fully open position where all the door panels overlap, and a fully closed position where the side edges of the first and second door panels, and the side edges of the second and third door panels, overlap, respectively, to close the opening edge. Engaging parts are provided on the side edges on the overlapping side when the sliding door is moved to the fully closed position, and these engaging parts engage with each other to restrict the door panels from moving apart in the thickness direction, and the engaging parts also engage with each other to have the effect of restricting the door panels from moving apart in the thickness direction (see Patent Document 3).

[0006] In a proposed storage furniture that has the luxury feel of ordinary furniture and a large storage space, an upper rail is provided over almost the entire width of the top plate of the storage device body, and a front sliding door is suspended and supported in front of the front face via a first support element that extends forward from this upper rail, so that the front face of the top plate is covered by the front sliding door and is configured to be slidable from the front face of one side plate of the storage device body to the front face of the other side plate, and a first deceleration means is provided at the top inside the storage furniture body to reduce the speed at which the front sliding door slides toward the closed position (see Patent Document 4).

[0007] There are few storage furniture with sliding doors that have newly integrated devices with rollers and guide rails that allow smooth opening and closing while minimizing the noise of movement when driving the left and right doors of large, special sliding doors, and that have sliding doors that move quietly and gently.In particular, there is no storage furniture that not only has the three characteristics of (1) handles attached to both the left and right corners of the sliding doors for easy opening and closing and wide use, (2) the doors close smoothly without any impact when opening and closing, and (3) the sound of the doors running on the rails is reduced to eliminate noise, but also has improved design, increased strength and earthquake resistance, a sturdy structure, and is lightweight.

[0010] Sliding doors for storage furniture and the like generally consist of two doors, with the outer and inner doors always fixed, and the handle positions are also fixed, which means that the handles do not fully achieve the storage volume of the interior space, and the inconvenient positioning of the door handles makes opening and closing difficult.In addition, friction occurs on contact depending on the weight, material, and shape of the door, so generally, doors are expected to open and close smoothly with a noise level of less than 45 dB, almost silently. Furthermore, when opening and closing a sliding door, two doors overlap each other, and when opening and closing in opposite directions, the two doors are often slightly offset and one door is moved to open and close the door. It is desirable to simplify this operation. While providing handles on the left and right corners of the doors is an option, this is not currently the case, either in terms of design or manufacturing.

[0011] In order to increase the storage capacity and make it easier to take things in and out of storage furniture, handles are attached to the left and right corners of the door. Since the position of the handle on a sliding door is fixed, in order to utilize the handle, the position is shifted by the width of the handle, which is inconvenient when storing items. It is expected that storage furniture with sliding doors will be created that has a wide storage space and is easy to operate.

[0012] This invention relates to storage furniture that can store items by opening and closing the sliding doors in the left-right direction, and is usually configured with two sliding doors. When these two doors overlap, items can be taken in and out of the storage, but this presents difficulties and the storage capacity is not fully utilized. Attempts have been made to improve the effectiveness of sliding doors for storage furniture that has sliding doors and handles. In particular, the shape of the opening located at the front, including the handle, has not been considered at present.

[0013] To provide a sliding door for furniture which has been made with attention to such problems and has a new function of being light and easy to install, as a sliding door for various types of storage furniture, which can store a large number of articles widely and easily, and has two similar handles and can be easily operated for storage, without impairing the elegance of the storage furniture. [Means for solving the problem]

[0014] In storage furniture with sliding doors, in order to maximize the opening and closing width of the storage space inside the sliding doors, to facilitate storage operations, and to operate the opening and closing operations quietly and safely, the two doors are the same shape, and recessed U-shaped handles are provided on both the left and right ends of the door frame, and poly pile, a flocked strip that prevents foreign objects from entering and increases cushioning, is attached to the left and right inner end faces and vertical edges, making it a furniture sliding door with new functions that allow the left and right sides to be used freely for opening and closing.

[0015] The two doors are made up of a sash frame and a surface material, the sash frame being made from wood, aluminum or resin, and the surface material being selected from a variety of materials including resin boards, wood boards and glass. A recessed U-shaped handle is positioned as a sash frame on both sides of the door, and the U-shaped handle has a recessed U-shaped hole groove so that it can be operated from the left or right. The U-shaped hole groove has a hole groove structure that is 15 to 20 mm wide and 5 to 10 mm deep, and by partially inserting a finger, it can be operated by touching both sides of the hole groove structure on both the left and right ends of the door, allowing it to be manually opened left or right. As fingers can engage the hole groove of the handle from either the left or right, and it is located on both ends, there are always three handles on the front, so even if the two doors overlap each other, it does not affect the opening and closing operation.

[0016] The two front and rear doors are identical in size and shape, and a polyester pile band that resembles a bundle of hair is attached in a vertical line to the vertical edges on both ends to prevent foreign objects from entering. To allow for quiet and safe sliding, a fixing pin is attached to the upper surface of the sash frame to which a runner with a two-way soft closer for opening and closing is attached, which allows for smooth sliding, and a resin roller that can run on a Y-shaped rail is attached to the lower surface.

[0017] The storage furniture with sliding doors is designed for books, ornaments and tableware, with dimensions of 800-2400mm wide, 1200-2200mm high and 300-600mm deep, with the sliding doors taking up 2 / 5 to 5 / 5 of the total surface area. The sliding doors have a wide opening with handles on both sides of the hole and groove structure on both ends of the door, and are made of a resin roller and aluminum rail structure that minimizes the contact surface when the sliding door opens and closes.

[0018] The frame with handles that make up the sash frames for the two doors and the upper and lower rails are made from aluminum and resin to reduce weight and prevent abnormal noise caused by contact between metals, and two inverted concave rectangular guide rails are attached to the upper sash frame of the sliding door opening of the storage furniture, and two Y-shaped recessed lower rails are attached to the lower sash frame, and a runner with a two-way open / close soft closer, which has dual double rollers inserted into both ends of a rectangular body with damper function, is inserted so that it can be operated, and sliding rollers that can rotate on the Y-shaped recessed lower rails are attached to two locations on the lower sash frame at the bottom, making it lightweight and operates gently and with reduced noise when opening and closing, and if a damping means is provided on the rails that do not come into collision contact with the sash frame of the sliding door when opening and closing, the storage furniture will have excellent sliding doors. [Effects of the Invention]

[0019] In the present invention, the sliding door for furniture with new functions is a sliding door that allows storage furniture with various sliding doors to store a variety of items more spaciously, can store a large amount of items, and is easy to operate for storing and retrieving. Moreover, it has a refined structure with a sliding door without compromising the elegance of the storage furniture in terms of appearance and design, and has a new function for opening and closing the door to which it is attached, allowing for smooth opening and closing and easy operation with less risk of damage to the storage furniture. The handles on the sliding door are designed so that fingers can be placed on either the left or right. Furthermore, since they are located on both ends of the door, there are two or three handles on the front, and even if the front and rear doors overlap, the opening and closing operation is not affected. By attaching sliding doors with rails and rollers to the interior of storage furniture and using it to store items, the elegance of the furniture is not compromised. The front of the furniture is roughly flush, ensuring the elegance of open storage furniture, and the sliding doors, which normally move gently with a quiet sound, now move extremely quietly, lightly, and smoothly from side to side, making storage more enjoyable.
