Abstract
Description
Technology Field
[0001] The present invention relates to a hinge coupling bracket structure that satisfies durability and allows the furniture to be slim and the hinge to be recessed, and satisfies durability, in accordance with the trend of adopting a structure in which the hinge, which is the structure for opening and closing the door using a hinge, rotates around the hinge and the hinge part is recessed into the furniture so that it is not visible from the outside, so that the furniture looks aesthetically pleasing when viewed from the outside. Background Technology
[0003] The present invention relates to a hinge coupling bracket structure. In household furniture, there is a trend to adopt a structure in which the door opens and closes using a hinge, and the hinge part is hidden inside the furniture so that it is not visible from the outside, so that the furniture looks aesthetically pleasing when viewed from the outside.
[0004] The reality is that consumer preferences are shifting, with consumers increasingly preferring hinge structures that are not visible from the outside and are only minimally visible when the door is opened.
[0005] Therefore, since consumers prefer to embed the hinge structure that allows the door to be opened and closed as much as possible within the wood or frame forming the furniture so that it is minimally exposed to them even when the door is opened, work was carried out to embed the hinge by forming a hinge insertion hole in the furniture. However, this is only possible if the wood or frame of the furniture that supports the hinge when opening and closing the door is thick enough for sufficient durability. On the other hand, consumers tend to prefer slim designs, so even if the furniture is made in a slim shape, sufficient durability is satisfied. Consumers prefer a structure where the door hinge is minimally visible even when the door is opened. As a result, furniture manufacturers are currently developing new structures to meet consumer preferences, and there is a need for a hinge coupling bracket structure that is slim, has an embedded hinge, and offers sufficient durability.

Specific details for implementing the invention
[0023] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the attached drawings. The objectives, features, and advantages of the present invention will be more easily understood by referring to the attached drawings and the following detailed description. Furthermore, in describing the present invention, if it is determined that a detailed description of related known components or functions may obscure the essence of the present invention, such detailed description is omitted.
[0024] Additionally, terms such as first, second, A, B, (a), (b), etc., may be used when describing the components of the present invention. These terms are intended only to distinguish the components from other components, and the essence, order, or sequence of the components is not limited by the terms. Where it is stated that a component is "connected," "combined," or "connected" to another component, it should be understood that the component may be directly connected or connected to the other component, but that another component may also be "connected," "combined," or "connected" between each component.
[0025] Furthermore, specific structural or functional descriptions in the present invention are illustrative of embodiments according to the concept of the present invention merely for the purpose of explaining embodiments according to the concept of the present invention, and embodiments according to the concept of the present invention may be implemented in various forms and should not be interpreted as being limited to the embodiments described in this specification or application.
[0027] FIG. 1 is a perspective view showing a recessed hinge (50) and a coupling bracket part (40) applied to furniture to which the present invention is applied, FIG. 2 is an exploded perspective view of a hinge bracket (22), a coupling bracket part (40), and a hinge (50), FIG. 3 is a side view of the coupled state of the hinge bracket (22), and FIG. 4 is a perspective view of a hinge bracket (22) coupled to a bracket coupling plate (18).
[0029] Referring to the drawings, the hinge coupling bracket structure of the present invention is shown in FIG. 1, where a hinge (50) is embedded and coupled to the lower plate (14) and the upper plate (16) of the furniture (10), respectively, and the shape of the furniture (10) is shown such that it rotates to open and close by being coupled to the upper and lower positions of the door (12).
[0030] Since consumers prefer a slim furniture shape and a neat structure in which the hinge used to open and close the door is embedded inside the furniture so that only a minimal hinge structure is visible even when the outer door is opened, if a hole is machined on the side of the furniture bottom plate (14) or furniture top plate (16) to insert the hinge and the hinge (50) is inserted and fixed, the furniture bottom plate (14) and furniture top plate (16), which are formed of wood material, tend to crack or break when external force is applied to open the door, as the durability is reduced due to the hole machined to insert and fix the hinge (50), and the durability is not secured due to the thin wood material.
[0031] Therefore, in order to ensure the durability of the slim furniture, it would be suitable to form a structure in which the hinge joint is made of metal and joined with the slim wood to ensure the aesthetics and durability of the furniture.
[0032] The bracket structure for forming slim furniture by combining with the hinge of the present invention is characterized by being composed of a hinge bracket part (20) that is coupled to the bottom plate (14) or the top plate (16) of the furniture so as to embed and install a hinge for opening and closing a door (12) in accordance with the slimming of the furniture, a coupling bracket part (40) that is slidably coupled to an insertion hole formed on the side of the hinge bracket part (20), and a hinge (50) that is coupled through an elongated hole formed on the upper surface of the coupling bracket part (40) and an elongated hole formed on one side of the front of the hinge bracket part (20).
[0033] In addition, the hinge bracket part (20) of the present invention is formed by extrusion and cut to a certain length according to the size of the furniture, and is characterized by forming a hinge insertion hole (24), which is an elongated hole into which a hinge (50) can be inserted, on one side of the front of the hinge bracket (22) in the direction in which the door (12) is installed.
[0034] Referring to FIG. 2, the hinge insertion hole (24), which is an elongated hole formed on one side of the front of the hinge bracket part (20), is inserted and coupled with the hinge body (52) and is coupled by being inserted into the hinge insertion hole (24) from the bottom surface (53) of the hinge body. The hinge insertion hole (24), which is an elongated hole formed on one side of the front of the hinge bracket part (20), can be manufactured at a lower cost in terms of productivity and economy by forming the elongated hole by press processing using a press, compared to processing by machine processing such as a lathe.
[0036] Referring to FIGS. 1 to 4, the hinge bracket portion (20) of the present invention is formed by extrusion into a long 'B' shape and is cut to be equal to the front length of the bracket coupling plate (18) of the furniture (10) so that the furniture plate coupling projection (21) and the coupling projection (23) of the hinge bracket (22) are fitted into the bracket coupling plate (18) and the coupling hole (32) of the bracket coupling plate (18). Inside the hinge bracket portion (20), there is a pair of 'L'-shaped 'C'-shaped bracket locking projections (26) for fixing and supporting a 'C'-shaped insertion bracket (42), a 'C'-shaped bracket support projection (28) that protrudes downward to support the 'C'-shaped insertion bracket (42) so as not to move from above, a hinge body support projection (27) that protrudes horizontally to support the hinge (50) left and right so as not to move, and the It is characterized by being composed of a hinge body support plate (25) formed by horizontal extrusion to support the hinge (50) vertically so as not to move, a coupling projection (23) formed to be coupled to a coupling groove (32) formed on the side of a bracket coupling plate (18) in the central part outside the hinge bracket part (20), a furniture plate coupling projection (21) into which the bracket coupling plate (18) is wrapped and fitted, and a hinge insertion hole (24) which is an elongated hole for coupling the hinge (50) formed on the front surface (34) of the hinge bracket (22) of the hinge bracket part (20).
[0037] The hinge bracket part (20) is a part where the front surface (34) of the hinge bracket is exposed to the user when the furniture (10) is opened, and is coupled to the door (12) so as to be rotatable through the hinge (50). In FIG. 1, the door (12) can be seen open through two embedded hinges (50) connected to the upper and lower parts of the furniture (10).
[0038] The hinge bracket part (20) has hinge bracket side (36) formed with furniture board connecting protrusions (21) on the left and right sides of the hinge bracket front (34) parallel to each other at a distance where the thickness of the furniture board can be fitted.
[0039] The hinge bracket part (20) has a hinge bracket cut surface (38) configured in a 'B' shape, and the hinge body bottom support plate (25), which is an internal horizontal reinforcing shape, supports the bottom surface of the hinge body (52) and at the same time reinforces the durability of the hinge bracket part (20).
[0040] Among the above 'ㅂ' shapes, the interior of the 'ㅁ' shape is composed of a 'ㄷ' shaped bracket insertion hole (38), a 'ㄷ' shaped bracket support projection (28) that presses the 'ㄷ' shaped insertion bracket (42), a pair of 'ㄴ' shaped bracket catch projections (26) formed to allow the 'ㄷ' shaped insertion bracket (42) to be caught and slide, a hinge body support projection (27) protruding horizontally to support the hinge (50) left and right so that it does not move, and a hinge body support plate (25) formed by horizontal extrusion that supports the hinge (50) forming the 'ㅁ' shaped bottom surface up and down so that it does not move and reinforces the strength of the hinge bracket (22).
[0041] Among the above 'ㅂ' shapes, the lower part of the 'ㅁ' shape has a connecting projection (23) formed to be connected to a connecting groove (32) formed on the side of the bracket connecting plate (18) in the central part outside the hinge bracket part (20), and a furniture plate connecting projection (21) into which the bracket connecting plate (18) is wrapped and fitted is formed in a reverse 'ㅂ' shape by protruding downward.
[0042] In addition, the upper surface of the 'ㅁ' shape among the above 'ㅂ' shapes is composed of a hinge insertion hole (24), which is an elongated hole for connecting the hinge (50) formed on the front surface (34) of the hinge bracket (22) of the above hinge bracket part (20).
[0043] The coupling bracket part (40) inserted into the 'C'-shaped bracket insertion hole (38), which is an insertion hole formed on the side of the hinge bracket part (20), is formed by press processing and is a 'C'-shaped insertion bracket (42), and is characterized by having a body insertion hole (44), which is an elongated hole formed in the 'C'-shaped insertion bracket (42) that is coupled by varying its position within the 'C'-shaped bracket insertion hole (38) in order to continuously insert the hinge (50) inserted through the hinge insertion hole (24).
[0044] The 'C'-shaped bracket insertion hole (38) of the present invention is characterized by being composed of a front surface of a hinge bracket (34), left and right hinge bracket sides (36), and a pair of 'C'-shaped bracket catch projections (26) formed in an 'L' shape on the inner surface of the hinge bracket sides (36).
[0045] A hinge insertion hole (24), which is formed by press processing on the front surface of the hinge bracket (22) and into which a hinge body (52) is inserted and coupled, and a body insertion hole (44), which is an elongated hole formed in a 'C'-shaped insertion bracket (42) that is coupled by varying its position within the 'C'-shaped bracket insertion hole (38), must be inserted and coupled by passing through them continuously. The reason for varying the position of the 'C'-shaped insertion bracket (42) within the 'C'-shaped bracket insertion hole (38) is to absorb the machining tolerance that may occur when the two insertion holes and the hinge body (52) are coupled, so that the position of the 'C'-shaped insertion bracket (42) can be varied within the 'C'-shaped bracket insertion hole (38). By varying the position, the machining tolerance between the hinge insertion hole (24) and the body insertion hole (44) can be eliminated, so productivity and machining accuracy are less constrained, and assembly tolerance can be easily reduced during assembly. It is a desirable configuration that is effective in reducing production costs as press processing is possible.
[0046] The present invention is characterized by inserting the hinge (50) into the hinge insertion hole (24) formed in the shape of an elongated hole in the hinge bracket (22) from the bottom surface (53) of the hinge body (52) formed in the shape of an elongated hole, moving the position of the body insertion hole (44) formed in the coupling bracket part (40) inserted into the 'U'-shaped bracket insertion hole (38) to penetrate the bottom surface (53) of the hinge body (52), inserting the hinge body (52) further so that the bottom surface (53) of the hinge body (52) comes into contact with the hinge body support plate (25), and inserting a screw into the furniture-side coupling hole (58) to connect to the hinge coupling hole (46) formed in the coupling bracket part (40) to screw-couple the hinge (50).
[0047] When inserting the hinge body (52) into the hinge insertion hole (24) formed in the shape of an elongated hole in the hinge bracket (22) from the bottom surface (53) of the hinge body (52), it is desirable to provide an assembly gap between the hinge body (52) and the hinge insertion hole (24) that is only large enough to facilitate assembly, because the door should not shake due to the size of the assembly gap when assembling the hinge body (52).
[0048] In addition, it is desirable to provide a gap between the hinge body (52) and the body insertion hole (44) that is only wide enough to facilitate assembly, for the same reason as described above.
[0049] The present invention is characterized in that the cross-section and bottom surface of the hinge body (52) have the same shape and are formed identically to the body insertion hole (44) formed in the coupling bracket part (40), the upper surface (55) of the hinge body is formed to be longer than the length of the hinge body (52) by the furniture-side coupling hole (58), and is formed with the same size and shape as the hinge insertion hole (24), which is an elongated hole formed in the hinge bracket (22).
[0050] The present invention provides a durable furniture by forming a bracket that reliably supports the recessed hinge, thereby creating a recessed structure that is not visible from the outside, so that the furniture with a door opening and closing structure can be viewed from the outside and the hinge part is embedded into the interior of the furniture itself so that it appears aesthetically pleasing, thereby providing a durable furniture.
[0051] In order to absorb the machining tolerance that may occur when the two insertion holes and the hinge body (52) are combined, the position of the 'C'-shaped insertion bracket (42) can be varied within the 'C'-shaped bracket insertion hole (38), thereby eliminating the machining tolerance between the hinge insertion hole (24) and the body insertion hole (44), thus allowing less concern with productivity and machining accuracy, and making it easier to reduce assembly tolerances during assembly, and also making it effective to reduce production costs as press processing is possible.
[0053] Those skilled in the art will understand that the present invention is not limited to the embodiments described above, but that various modifications and variations are possible within the scope of not altering the essence of the invention.
[0054] Accordingly, the embodiments described above are provided to fully inform those skilled in the art of the scope of the invention and should be understood as illustrative in all respects and not restrictive, and the invention is defined only by the scope of the claims.
