Description

Technology Field

[0001] The present invention relates to a round corner connecting structure for furniture, and more specifically, to a round corner connecting structure for furniture in which a plurality of plate members are connected to a round corner member to form a corner portion of the furniture in a curved shape, thereby preventing damage to a decorative film attached to the outer surface and improving safety. Background Technology

[0003] Generally, furniture such as kitchen cabinets, built-in wardrobes, chests of drawers, display cabinets, living room cabinets, bookshelves, and bed frames is manufactured using panel materials like plywood or MDF (Medium Density Fiberboard), and is constructed by joining side panels, top panels, and back panels together. In this process, a structure is commonly used in which panels of a certain thickness are placed perpendicularly to each other and joined using screws or fasteners.

[0004] However, in such conventional furniture, the panels are joined at right angles, resulting in sharp corners, which raised concerns that users might bump into the corners and cause safety accidents.

[0005] Meanwhile, it is common practice to attach a decorative film with a specific color or pattern to the outer surface of the aforementioned plywood or MDF to enhance aesthetics. Conventionally, in order to realize these panels in a round shape without a separate corner connection structure, a method was used in which the boundary of two panels in contact with each other was cut at a predetermined angle, for example, about 45 degrees, and then joined by butting them together.

[0006] However, in the above method, fine gaps are prone to forming at the boundary between the two panels, and there was a problem where the decorative film would lift or break at that area. In particular, tensile or torsional stresses are concentrated at the boundary due to external impacts or vibrations occurring during furniture use, and shrinkage and expansion stresses are repeatedly applied during temperature changes due to the difference in the coefficient of thermal expansion between the panels and the decorative film, causing the relatively thin and low-strength decorative film to be easily damaged.

[0007] To mitigate these problems, a method of attaching separate rounded protective members to the corners of furniture has been proposed in the past. However, in this case, the exposure of the separate members to the outside reduced the sense of unity of the furniture and compromised its aesthetics.

[0008] In addition, Korean Patent Publication No. 10-2835958 is disclosed as a technology to solve a problem similar to the above; however, this technology adopts a structure in which a separate installation groove is formed to form a rounded portion and a protective pad is inserted inside, which has limitations such as a complex processing process and reduced assemblability.

[0036] <1st Example>

[0037] As illustrated in FIG. 1, the first embodiment of the round corner connecting structure for furniture according to the present invention is schematically composed of a round corner member (100) and an outer finishing member (200) that is positioned on the outside of the round corner member (100) and surrounds it.

[0038] The above components are explained in detail as follows.

[0039] The above round corner member (100) is configured to form a round shape in the corner portion of furniture and may be configured to include a plurality of round corner forming plates (110) arranged to face each other, and a pair of lateral connecting plates (120) coupled to both sides of the round corner forming plates (110) and extending in the longitudinal direction.

[0040] The round corner forming plate (110) is configured to be combined with the outer finishing member (200) to form a continuous curved surface, and accordingly, the outer finishing member (200) can be formed continuously without interruption.

[0041] The round corner forming plate (110) may be formed as a plate having a curved portion (111) located in the center to form a round shape for the corner portion of the furniture, and a pair of connecting plate coupling portions (113) located on both sides relative to the curved portion (111).

[0042] The above curved portion (111) may be formed to have a certain radius of curvature to form a rounded shape for the corner portion of the furniture, and the radius of curvature may be set in a range of, for example, about 100 mm to 200 mm.

[0043] Additionally, the curved portion (111) may be formed in correspondence with the joining angle of the intersecting plates, for example, the plates may be joined at an angle of about 60 to 120 degrees, and more specifically, may form a right angle structure of about 90 degrees.

[0044] Accordingly, the curved portion (111) forms a continuous curved surface with the outer surface of the plate, allowing the decorative film attached to the outer surface to be attached stably without interruption, and can prevent damage to the decorative film by alleviating stress concentration upon external impact, while simultaneously improving the safety and durability of the furniture. The radius of curvature and the joining angle can be varied depending on the use of the furniture, the thickness of the plate, and the material.

[0045] The above connecting plate coupling portion (113) may be formed in the shape of a groove having a flat surface that is recessed to a certain depth from the curved portion (111) when the round corner forming plate (110) is viewed from the front so as to be coupled with the side connecting plate (120). However, the above connecting plate coupling portion (113) may be formed in any shape to induce or facilitate coupling with the side connecting plate (120), and for example, it may be formed to include a protruding shape, a step structure, a fastening hole, or a coupling inducing structure equivalent thereto to correspond to the side connecting plate (120). In addition, as one embodiment, the above connecting plate coupling portion (113) may be formed to be coupled by a fastening method using a coupling member such as a bolt, but is not limited thereto, and a snap-fit ​​coupling, a snap-fit ​​coupling, a magnetic coupling using a magnet, or a coupling method using an adhesive may also be applied.

[0046] In addition, the pair of connecting plate coupling parts (113) may be formed to form a predetermined angle with respect to the curved surface part (111) as one embodiment, for example, in a range of about 60 to 120 degrees, but are not limited thereto.

[0047] The above-mentioned lateral connecting plate (120) is formed in the shape of a rectangular plate, is placed in close contact with the recessed flat surface of the connecting plate coupling part (113), and is fixedly connected by a connecting member such as a bolt.

[0048] Additionally, the round corner member (100) is formed by combining a pair of round corner forming plates (110) and a pair of lateral connecting plates (120) as one embodiment, but is not limited thereto and, depending on the structure and installation conditions of the furniture, the round corner forming plates (110) and the lateral connecting plates (120) can each be formed in various ways by changing them into multiple numbers.

[0049] At this time, when the round corner forming plate (110) is formed in multiple numbers, the support area for the corner portion increases and the load is distributed, thereby improving structural stability and allowing the bonding state with the plate material (200) to be maintained more firmly.

[0050] The outer finishing member (200) is formed integrally with the outer finishing member (200) so that a pair of inner connecting members (210) are spaced apart at a certain distance, and a round corner member connecting part (201) is formed between the inner connecting members (210) to which a round corner member (100) is connected, and has a plate-shaped structure having flexibility that can be bent.

[0051] The outer finishing member (200) is attached to the outer surface of the round corner member (100), thereby improving the appearance quality and protecting the round corner member (100) from scratches, contamination, and ultraviolet rays.

[0052] The round corner member coupling part (201) can be formed with a thickness in the range of 0.5 mm to 1.5 mm, and in one embodiment, by having a thickness of about 1 mm, it can be elastically coupled to the outer surface of the round shape of the round corner member (100) through elastic deformation.

[0053] The inner connecting member (210) is a supporting member that is connected to both sides of the round corner member (100) to provide structural rigidity, and is formed in the shape of a rectangular plate.

[0054] Additionally, the outer finishing member (200) may have a functional coating layer additionally formed on its outer surface, and the functional coating layer may be formed as a single layer or multilayer structure comprising at least one of a hard coating layer, a UV blocking layer, a water-repellent or oil-repellent coating layer, an antibacterial coating layer, or an antifouling coating layer. In this case, the hard coating layer may be formed to include a thermosetting resin or a UV-curable resin, and the resin may also be applied to at least some of the layers constituting the functional coating layer. Additionally, the functional coating layer may be formed through a coating, coating, deposition, or laminating process.

[0055] Additionally, the round corner member (100) and the outer finishing member (200) may be formed from wood-based materials such as solid wood, compressed wood, densified wood, or synthetic wood, and may include MDF (medium density fiberboard) formed by mixing wood powder with an adhesive. Furthermore, they may be formed from metal materials such as aluminum or stainless steel, synthetic resin materials such as ABS, PVC, or polycarbonate, or composite materials formed by combining these.

[0057] <2nd Example>

[0058] As illustrated in FIG. 4, a second embodiment of a round corner connecting structure for furniture according to the present invention includes a round corner member (100) in the same manner as the first embodiment, but is characterized in that a pair of inner connecting members (210) and outer finishing members (200) are formed to be separated from each other.

[0059] Specifically, a second embodiment of a round corner connecting structure for furniture according to the present invention comprises a round corner member (100), a pair of inner connecting members (210) coupled to both sides of the round corner member (100), and an outer finishing member (200) coupled to the outside of the round corner member (100) and the inner connecting members (210).

[0060] The inner coupling member (210) may be bonded to the outer finishing member (200) using adhesive bond, double-sided tape, etc., but is not limited thereto and may be bonded by a snap-fit ​​bond or mechanical bonding method.

[0061] The round corner member coupling portion (201) of the outer finishing member (200) is similar to the first embodiment in that it is a part that is coupled with the round corner member (100), but as the outer finishing member (200) and the inner coupling member (210) are formed separately from each other, it can be configured to be coupled with the round corner member (100) by a structure formed in the outer finishing member (200) itself.

[0062] Other round corner member (100), inner connecting member (210) and outer finishing member (200) are identical to the configuration of the first embodiment, so a detailed description is omitted.

[0064] The first and second embodiments of the round corner connecting structure for furniture according to the present invention can be applied to various types of furniture such as kitchen furniture like sinks, office furniture, storage cabinets, built-in wardrobes, display cabinets, as well as interior finishing structures, exhibition structures, or other structures having corner sections.

[0065] In the foregoing, the configuration and operation of the round corner connecting structure for furniture according to the present invention have been illustrated with reference to the detailed description and drawings; however, this is merely an example, and various changes and modifications are possible within the scope of the technical concept of the present invention.
