Abstract
Description
Technical Field
[0001] The present invention relates to a storage furniture with a sliding door, in which a digging type U-shaped handle is provided at both left and right ends of the door rail frame in order to make the storage space as wide as possible, simplify the storage operation, and make the opening and closing operation of the sliding door quiet and safe. The present invention relates to a sliding door for furniture having a new function that the handles on both left and right ends of the door can be manually operated freely.
Background Art
[0002] Conventionally, in storage furniture provided with a sliding door that can open and close in the left and right directions to store items to be stored, it is usually composed of two doors. When these two doors overlap, the items inside can be taken in and out sufficiently, but it is difficult and the storage capacity cannot be fully utilized. Also, since one door cannot be used in either the left or right direction, the storage operation is often troublesome. Furthermore, there is a problem of generating frictional noise during sliding on the upper and lower rails of the door of the storage furniture. Improvements to the sliding door have been attempted for such storage furniture. Currently, in particular, consideration is being given to the shape including the opening on the front side, the two horizontally formed rails, or the weight reduction of each sliding door, and a more effective handle.
[0003] As furniture with a sliding door that can quietly, safely, and smoothly open and close two sliding doors with a smooth operation feeling and a low-noise drive that has a smooth and easy opening and closing feeling, two reverse concave rectangular guide rail bodies are provided on the upper rail frame of the opening for the sliding door of the storage furniture, and two Y-shaped dug-in lower rails or two integrated Y-shaped dug-in lower rails are provided on the lower rail frame. A runner with a soft closer for opening and closing in two directions, in which dual double rollers are inserted at both tip ends of a rectangular parallelepiped, is inserted into the upper rail body for reverse concave rectangular guide covered with a box-shaped cover frame having a damper function so that it can slide. A sliding door has been proposed (see Patent Document 1).
[0004] In a sliding door that can move between a fully open position where the door panels substantially overlap and a fully closed position where this overlap substantially disappears, first to third door panels that are parallel to each other are connected to each other via a link mechanism, and in a sliding door that can move between a fully open position where these door panels substantially overlap and a fully closed position where this overlap substantially disappears, the link mechanism comprises a first link member whose base end is pivotally attached 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 is connected to the pivot end of the first link member, and a second link member whose one end is connected to the movable shaft member and whose other end is pivotally attached to the rear surface of the third door panel. (See Patent Document 2).
[0005] A sliding door has been proposed that is installed in an opening and has multiple door panels. The sliding door has multiple door panels installed at the opening end of a storage furniture that is an opening. These door panels are configured to be movable between a fully open position where all door panels overlap and a fully closed position where the side ends of the first door panel and the second door panel, and the side ends of the second door panel and the third door panel, overlap and close the opening end. When the sliding door is moved to the fully closed position, engaging parts are provided on the overlapping side ends. These engaging parts engage with each other to restrict the separation movement between the door panels in the thickness direction, and the engaging parts engage with each other to restrict the separation movement between the door panels in the thickness direction (see Patent Document 3).
[0006] In a storage furniture that possesses a sense of luxury in general furniture while also having ample storage space, a storage furniture has been proposed in which an upper rail is provided on the top plate of the storage unit body, extending substantially across the entire width direction, and a front sliding door is suspended and supported in front of the front surface via a first support element extending forward from this upper rail, so that the front surface of the top plate is covered by the front sliding door and the front sliding door is configured to slide from the front surface of one side plate of the storage unit body to the front surface of the other side plate, and a first deceleration means is provided above the inside of the storage furniture body to reduce the speed at which the front sliding door slides toward closing (see Patent Document 4).
[0007] In storage furniture with sliding doors, there are few pieces of furniture with sliding doors that have been newly integrated with rollers and guide rails that minimize noise when driving the left and right doors of large, special sliding doors, allowing for smooth opening and closing. In particular, there are no pieces of storage furniture that have sliding doors that move quietly and gently, in addition to the three characteristics of ▲1▼ having handles on both the left and right corners of the sliding door for easy opening and closing and wide use, ▲2▼ the door closing smoothly without any abrupt slamming when opening and closing, and ▲3▼ noise reduction in the movement of the door on the rail to eliminate noise, while also enhancing the design, increasing the strength and earthquake resistance of the furniture, and making it sturdy, and yet being lightweight.

[0010] In sliding doors for storage furniture, there are generally two doors, with the outer and inner doors always fixed in place, and the handle positions are also fixed. However, the position of the handles can prevent the storage volume of the interior space from being fully realized, and the inconvenience of the handle positions can cause many difficulties in opening and closing the doors. In addition, friction caused by the weight, material, and shape of the doors generates noise at the point of contact, and generally, there is an expectation that doors should open and close smoothly and almost silently at a noise level of 45 dB or less. Furthermore, when opening and closing sliding doors, the two doors overlap, and when opening or closing in opposite directions, the two doors are often slightly offset, and one door is moved to proceed with the opening and closing operation. There is a desire to simplify this operation. That is, to provide handles on the left and right corners of the door, but this is not done due to design or manufacturing constraints.
[0011] To facilitate easy access to stored items and increase storage capacity, the storage furniture has handles on the left and right corners of the doors. However, because the position of the handles is fixed on the sliding doors, they are offset by the width of the handles to make them usable, which makes it inconvenient when putting items inside. There is a desire for storage furniture with sliding doors that offer a wider storage capacity and are easier to operate.
[0012] This invention relates to storage furniture that allows items to be stored by opening and closing sliding doors from side to side. Typically, this furniture is equipped with two sliding doors. While it is possible to access the stored items inside when these two doors are overlapping, this is difficult, and the storage capacity is not fully realized. Attempts have been made to improve the effectiveness of sliding doors in such storage furniture with sliding doors and handles. In particular, the shape of the opening located on the front side, including the handle, has not been adequately considered.
[0013] This invention addresses these challenges and aims to provide a sliding door for furniture that offers a wide and ample storage space for various types of storage furniture, is a two-door sliding door with handles that allows for easy storage, does not detract from the aesthetic appeal of the furniture, and has a new function that makes the sliding door light and easy to install. [Means for solving the problem]
[0014] In storage furniture with sliding doors, the two doors are identical in shape, and each door has recessed U-shaped handles at both ends of the door frame. Polypile, a type of flocked strip, is attached to the inner left and right end surfaces and the vertical end surface to prevent foreign objects from entering and to enhance cushioning. This new sliding door for furniture allows for free use of either the left or right side when opening and closing the door.
[0015] The two doors consist of a frame and a surface material. The frame is made from wood, aluminum, or resin, and the surface material is made from resin, wood, or glass. A recessed U-shaped handle is positioned at both ends of the door frame. The U-shaped handle has a recessed U-shaped groove that allows it to move left and right. The groove has a width of 15-20 mm and a depth of 5-10 mm. By partially inserting a finger, the door can be operated by touching both sides of the groove structure at both ends of the door. Because the fingers can grip the groove from either the left or the right, and there are handles at both ends, there are always three handles on the front, and the opening and closing operation is not affected even when the two doors overlap front and back.
[0016] The two front and rear doors are identical in dimensions and shape. Poly pile strips, resembling bundles of hair, are attached in vertical lines along the left and right edges to prevent foreign objects from entering. To ensure quiet and safe sliding, the upper surface of the frame is fitted with fixing pins to which runners with two-way soft closers that allow for smooth opening and closing are attached, and the lower surface is fitted with resin rollers that can run on a Y-shaped rail.
[0017] The sliding door storage furniture has dimensions of 800-2400mm in width, 1200-2200mm in height, and 300-600mm in depth. The sliding doors occupy 2 / 5 to 5 / 5 of the entire surface, making it suitable for storing books, decorative items, and tableware. The sliding doors have handles on both sides of the grooved structure at both ends of the door, and the opening is wide. The sliding doors are constructed with resin rollers and aluminum rails to minimize the contact surface during opening and closing.
[0018] The frame with handles and the upper and lower rails of the two doors are made of aluminum and resin to reduce weight and prevent abnormal noise caused by metal-to-metal contact. Two inverted concave rectangular guide rails are attached to the upper frame of the sliding door opening of the storage furniture, and two Y-shaped recessed lower rails are attached to the lower frame. A runner with a two-way soft closer, which has dual double rollers with damper function inserted into both ends of the rectangular upper rail, is inserted in an operable manner. Additionally, two slide rollers that can rotate on the Y-shaped recessed lower rails are attached to the lower frame. This results in a storage furniture with excellent sliding doors that are lightweight, operate smoothly and quietly during opening and closing, and have mitigating mechanisms in the rails to prevent collisional contact between the sliding door frame and the frame during opening and closing. [Effects of the Invention]
[0019] In this invention, the sliding door for furniture with a new function is designed for storage furniture with various sliding doors, allowing for more storage space and quantity of various items, and making it easy to store and retrieve items. Moreover, it maintains the dignified appearance and design of the storage furniture, resulting in a dignified structure with a sliding door. The sliding door has a new function that allows for smooth opening and closing, and is easy to operate, with a low risk of damage to the storage furniture. Furthermore, the handle on the sliding door is designed so that fingers can grip it from either the left or right side. In addition, there are handles on both ends of the door, resulting in 2 to 3 handles on the front, and the opening and closing operation is not affected even when the front and back doors overlap. When a sliding door with rails and rollers formed inside the storage furniture is attached and used to store items as storage furniture, the style is not impaired. The front of the furniture is made flush to ensure the style of the open storage furniture, and the sliding door in the furniture that makes a gentle movement with a quiet sound moves extremely quietly, smoothly, and gently from side to side, creating a sense of enjoyment during storage.

Figs. 2, 3, and 5 show each state, and Fig. 4 is a diagram showing the types of furniture using the sliding door.
Examples
[0022] In storage furniture with sliding doors, when one side is opened, the opening width of the storage space inside the sliding door is maximized to facilitate storage operations, and the doors are opened and closed quietly and safely. To achieve this, the two doors are the same shape, and recessed U-shaped handles are provided at both the left and right ends of the frame of each door. Polypile, a fuzzy strip that prevents foreign objects from entering and enhances cushioning, is attached to the inner left and right end surfaces and vertical edges of the doors, and the sliding doors have a new function that allows them to be opened and closed freely in all directions (front, back, left, and right).
[0023] The two doors of the cupboard in Figure 1 are located on the upper level, and the frame is made from wood, aluminum, or resin, while the surface material is made from resin or glass. As shown in Figures 2, 3, and 5, recessed U-shaped handles made of aluminum frame are positioned at both ends. The U-shaped handles are recessed into U-shaped grooves so that they can be operated from side to side. The U-shaped grooves have a width of 15 mm and a depth of 10 mm, and the handles can be operated freely from side to side by touching the sides of the groove structures at both ends by partially inserting a finger.
[0024] The two front and rear doors of the upper section of the cupboard are identical in dimensions and shape. As shown in Figure 5, a poly pile band resembling bundles of hair is attached in a vertical line along the left and right edges to prevent foreign objects from entering. As shown in Figure 2D, a poly pile band is attached in a vertical line along the left and right edges. To ensure quiet and safe operation, a fixing pin section is attached to the upper surface of the frame of the two doors, allowing a runner with a two-way soft closer to be suspended for smooth operation, as shown in Figure 1. A resin roller that can run on a Y-shaped rail is attached to the lower surface.
[0025] The sliding door for furniture with the new function shown in Figure 4A has dimensions of 900mm in width, 1800mm in height, and 450mm in depth. It consists of a counter with hinged doors, drawers, and a space at the bottom, and a shelf with a sliding door at the top. The lightweight sliding door accounts for 2 / 5 of the total surface area of the storage furniture, which is a storage unit for dishes. The sliding door has a wide opening with handles on both sides of the grooved structures at both ends, and the contact surface during opening and closing the door is minimized. The sliding door has a rail structure that reduces the contact surface between the resin roller and the aluminum rail, and consists of two door-driving guide rails and a rail structure that resembles a door frame and a sliding door frame.
