[0046] Hereinafter, embodiments will be described in detail with reference to the attached drawings, provided that identical or corresponding components are given the same reference number regardless of the drawing symbols, and redundant descriptions thereof will be omitted.

[0047] FIG. 1 is a cross-sectional view illustrating a hidden door assembly according to an embodiment of the present invention, FIG. 2 is a partial enlarged view illustrating an enlarged portion of the hidden door assembly shown in FIG. 1, and FIG. 3 to 5 are reference drawings illustrating the construction sequence of the hidden door assembly.

[0048] Referring to the drawings, a hidden door assembly (10) according to an embodiment of the present invention includes a door frame (11), a door frame (100), a hinge (300), and a door (400).

[0049] First, the door frame (11) is fixed along the leading edge of the area (12) that is opened to install the door (400) on the wall (W). The door frame (11) is usually installed with wood, but is not limited to this.

[0050] The door frame (11) is installed on both sides and the top surface exposed in the open area (12) of the wall (W), and is installed in a shape approximately like a “П” when viewed from the front, excluding the bottom surface.

[0051] The door frame (100) is fixed with a portion of it inserted between the door frame (11) and the wall (W). The door frame (100) is described as being made of aluminum as an example, but the material is not limited thereto.

[0052] The door frame (100) includes a left frame portion (100a) located in the direction where the hinge (300) is installed, a right frame portion (100b) located opposite the left frame portion (100a), and an upper frame portion (not shown) arranged to connect the upper ends of the left frame portion (100a) and the right frame portion (100b). Additionally, the left frame portion (100a), the right frame portion (100b), and the upper frame portion can be applied by extruding a single door frame (100) and arranging them at their respective locations so that only their directions are opposite. That is, they can be formed with the same shape, differing only in their positions or directions.

[0053] The top of the left frame part (100a) and one end of the upper frame part (100c) (100c) may be fixed by being cut diagonally at a 45° angle to each other, and the top of the right frame part (100b) and the other side of the upper frame part may also be fixed by being cut diagonally at a 45° angle to each other. Alternatively, the top of the left frame part (100a) and one end of the upper frame part may be cut diagonally at a 45° angle to each other and assembled from the outside through a separate “L” angle frame (not shown), and the top of the right frame part (100b) and the other side of the upper frame part may also be cut diagonally at a 45° angle to each other and assembled from the outside through a separate “L” angle frame (not shown).

[0054] And, a hinge (300) is attached to the left door frame to allow the door (400) to rotate.

[0055] The hinge (300) includes a fixed member (310) fixed on the first finishing member (21), a shielding member (320) hinged to be rotatable on the fixed member (310) and having one cross section formed in an arc shape, and a rotating member (330) hinged to be rotatable on the fixed member (310) and having one cross section formed in a "U" shape to be connected to one side of the door (400). Here, the shielding member (320) and the rotating member (330) are arranged to be rotatable around the same rotation axis (340) from the fixed member (310).

[0056] Therefore, when the door (400) is opened, if the rotating member (330) rotates around the rotation axis (340), the shielding member (320) is exposed in an arc shape, so it is possible to prevent a safety accident from occurring as a part of the user's body gets caught.

[0057] Additionally, the pivot member (330) has a guide member (331) protruding in the direction of the door (400) on a plane parallel to the axis of rotation. The guide member (331) can provide a function of guiding the connection position between the hinge (300) and the door (400) while preventing light leakage between them.

[0058] The hinge (300) can be provided as a structure that is connected along the longitudinal direction on the left frame portion (100a). That is, since the hinge (300) is covered integrally along the vertical direction between the left frame portion (100a) and the door (400), the hinge (300) can be seen to correspond to one side of the door (400) when looking at the door (400) from the inside as in FIG. 1.

[0059] Also, the door frame (100) includes a first frame (110) to a third frame (130). Since the structure of the left frame section (100a), the right frame section (100b), and the upper frame section of the door frame (100) is identical, the following description will be based on the door frame (100) with respect to the left frame section (100a).

[0060] The first frame (110) of the door frame (100) is positioned in close contact with the front end of the wall (W) and is inserted into the fixing groove (14) formed between the door frame (11) fixed on the wall (W) and the wall (W). Additionally, the first frame (110) can be firmly fixed to penetrate the wall (W) together with the door frame (11) using anchor bolts.

[0061] The second frame (120) is bent at 90° from one end of the first frame (110) and extended toward the door (400).

[0062] The third frame (130) is bent 90° outward from the leading edge of the second frame (120). At this time, the outward direction may be the living room side, for example in the case of a house, and the inward direction may be the room side. The protruding height of the third frame (130) may be formed to be equal to or longer than the thickness of the second finishing member (22) mounted on the outer side of the second frame (120). In this embodiment, it is preferable that the height of the third frame (130) be configured to protrude about 1 mm more than the second finishing member (22).

[0063] In addition, the first frame (110) is provided with at least one protrusion (111) on the inner side facing the door frame (11) along the longitudinal direction. In this embodiment, one protrusion (111) is formed as an example, but the number of protrusions (111) is not limited thereto. The protrusion (111) can be positioned to contact the door frame (11) inside the fixing groove (14).

[0064] A connecting groove (113) is formed around a protrusion (111) that does not come into contact with the door frame (11) on the first frame (110), and an adhesive member for attaching the door frame (100) to the door frame (11) may be provided in the connecting groove (113). For example, the adhesive member may be an adhesive or silicone.

[0065] On the outer side of the first frame (110), a coupling groove (112) is formed along the longitudinal direction in at least a portion inwardly in the part facing the wall (W). The angle frame described above can be mounted in the coupling groove (112), or another adhesive member can be provided between the wall (W) and the first frame (110) to increase the adhesion between them.

[0066] A protective frame (115) is provided on the inner side of the second frame (120) and the third frame (130). The protective frame (115) may be made of the same material as the door frame (100), or may be made of plastic or wood in addition to metal to provide an aesthetic interior effect.

[0067] The protective frame (115) includes a first protective member (116) that is in close contact with the second frame (120) and a second protective member (117) that is in close contact with the third frame (130).

[0068] The protective frame (115) can be attached to the door frame (100) or fastened via fasteners after the interior construction is completed, thereby covering any damage to the door frame (100). Therefore, even if some damage occurs to the door frame (100) while moving through the open area (12), which is the door space, during the interior construction, the protective frame (115) covers it after the construction is completed, thus providing the advantage of solving this problem.

[0069] A slip prevention pattern (118) may be provided between the surfaces where the protective frame (115) and the door frame (100) come into contact. The second frame (120) and the first protective member (116) may have a slip prevention pattern (118) provided on surfaces facing each other and may be formed to engage with each other in the direction of their connection.

[0070] For example, the anti-slip pattern (118) may be formed as a wave pattern. In this case, the wave patterns formed to face each other on the second frame (120) and the first protective member (116) may mesh with each other when they are combined. Of course, the anti-slip pattern (118) may be formed as a sawtooth pattern or a dot pattern, in addition to the wave pattern.

[0071] Accordingly, the protective frame (115) has the advantage of preventing slip from occurring from the door frame (100) toward the door (400) and increasing their adhesive or fixing strength.

[0072] When the protective frame (115) is attached to the door frame (100), the first finishing member (21) is attached to the door frame (100) so as to correspond to the area where the first frame (110) and the door frame (11) overlap.

[0073] Then, a hinge (300) is attached to the first finishing member (21). The fixing member (310) of the hinge (300) penetrates the first finishing member (21) and is fixed to the door frame (11) through a fastener. This construction structure has the effect of increasing constructability because, if the installation position of the hinge (300) is incorrect or the construction of the first finishing member (21) is poor, only the first finishing member (21) can be replaced and re-constructed.

[0074] Additionally, the hidden door assembly (10) may be provided with a second finishing member (22) that covers the wall (W) on the outer surface of the second frame (120) and the third frame (130), and a third finishing member (23) that covers the outer surface of the door frame (11) on the side of the first finishing member (21).

[0075] Next, the door (400) includes a first area (410) positioned parallel to the side line of the pivot member (330) and a second area (420) positioned parallel to the line of the third frame (130) of the door frame (100). That is, when the door (400) is closed, the first area (410) is located between the first finishing member (21) of the left door frame and the first finishing member (21) of the right door frame, and the second area (420) is located between the second protective member (117) of the left door frame and the second protective member (117) of the right door frame. Of course, the door (400) can be composed of the first area (410) and the second area (420) as a single unit.

[0076] And, the second area (420) of the door (400) protrudes further in the direction of the right frame part (100b) than the first area (410), and the second area (420) also protrudes further in the direction of the upper frame part than the first area (410). Accordingly, during the process of closing the door (400), the leading edge of the second area (420) in the direction of the right frame part (100b) is positioned to interfere with the second protective member (117) of the right frame part (100b), and at the same time, the second area in the direction of the upper frame part can be positioned to interfere with the second protective member of the upper frame part.

[0077] Additionally, the second area (420) of the door (400) is positioned so that the hinge (300) is partially exposed in the direction of the left frame portion (100a), and is spaced apart from the third frame (130) or the second protective member (117) to form a safety groove (13) between them. Of course, if the width or thickness of the second area (420) is minimal, the safety groove (13) may be omitted. This safety groove (13) has the effect of preventing safety accidents, such as hand pinching, on the outside of the door (400).

[0078] And, as the second area (420) interferes with the second frame (120), the closed state of the door (400) is set, and at the same time, light leakage between the inner and outer sides (e.g., between a room and a living room) can be prevented with respect to the closed door (400).

[0079] Additionally, a cushioning member (122) may be provided on the surface where the second area (420) and the second protective member (117) face each other on the door (400), and on the surface where the first area (410) faces the first protective member (116). The cushioning member (122) can prevent noise caused by contact between the door (400) and the protective frame (115) as the door (400) closes, and furthermore, additional soundproofing and windproofing functions can be implemented.

[0080] Although not shown in the drawing, the cushioning member (122) may be formed in the shape of a foam tape having a set thickness and may have a structure in which the first region (410) and the second region (420) are each attached to adjacent stepped regions. This cushioning member is made of a flame-retardant material, is resistant to fire, and has the advantage of being easy to attach or fix.

[0081] FIG. 6 is a cross-sectional view illustrating a hidden door assembly according to another embodiment of the present invention, FIG. 7 is a partial enlarged view illustrating an enlarged portion of the hidden door assembly shown in FIG. 6, and FIG. 8 is a cross-sectional view illustrating each component of the hidden door assembly shown in FIG. 7 in disassembly.

[0082] Referring to the drawings, a hidden door assembly (20) according to another embodiment of the present invention includes a door frame (11), a door frame (100'), a fixing member (200), a hinge (300), and a door (400).

[0083] In this embodiment, the door frame (11) is independently fixed along the leading edge of the open area (12) of the wall (W).

[0084] In addition, the hidden door assembly (20) according to another embodiment of the present invention differs in the configuration of the door frame (100') and the fixing member (200), and since other configurations are the same as described above, only the differences will be explained in detail.

[0085] First, the door frame (100') includes the first frame (110) to the fourth frame (140).

[0086] The structure of the first frame (110) to the third frame (130) is the same as the structure described above. However, the first frame (110) is not fixed while being inserted between the door frame (11) and the wall (W), but is independently fixed on the front end (12) of the wall at the side of the door frame (11).

[0087] The fourth frame (140) is bent at a 90° angle at the other end of the first frame (110) and positioned to face the second frame (120). Additionally, a roughly rectangular mounting groove (101) is formed between the first frame (110), the second frame (120), and the fourth frame (140). A fixing member (200) is inserted into the mounting groove (101) and secured. The fourth frame (140) may be shorter in length than the second frame (120).

[0088] The second frame (120) and the fourth frame (140) each have a sawtooth pattern (121) on their respective facing surfaces. That is, the second frame (120) and the fourth frame (140) have a sawtooth pattern (121) formed on their inner surfaces facing the mounting groove (101), so that when the fixing member (200) is inserted, it can be provided with an interference structure that is difficult to remove again.

[0089] Additionally, the width of the fourth frame (140) is smaller than the width of the second frame (120), but it has a width that allows the first finishing member (21) to be inserted at least partially even after accommodating the fixing member (200) inside. Therefore, the first finishing member (21) can be partially accommodated inside the mounting groove (101).

[0090] Then, the fixing member (200) is fixed by being inserted into a mounting groove inside the door frame. The fixing member is made of wood, but is not limited thereto. After the fixing member (200) is inserted so as to contact the protrusion (111) inside the mounting groove (101), the fixing member (200) can be fixed by fastening a fastener (F) to at least one side of the second frame (120) and the fourth frame (140). Of course, in this embodiment, the fasteners are shown as being fastened toward the fixing member (200) on both the second frame (120) and the fourth frame (140) as an example.

[0091] A first finishing member (21) is attached to the outer side of the fixed member (200).

[0092] And, a hinge (300) is attached to the left door frame so that the door (400) can rotate. Since the structure of the hinge (300) and the door (400) is the same as that of the embodiment described above, a redundant description is omitted.

[0093] As shown in FIG. 8, a cushioning member (600) may be further provided in the stepped portion where the first area (410) and the second area (420) of the door (400) are adjacent. Of course, although not shown in the drawings, the cushioning member (122) disclosed in the above-described embodiment may also be applied.

[0094] The buffer member (600) may include a hard member (610) attached to the outer surface of the second area (420) and the first area (410) facing the second frame (120), and a soft member (620) that extends from each end of both sides of the hard member (610) toward each other in a diagonal direction, with the central area cut off.

[0095] The cushioning member (600) can reduce noise caused by friction between the door (400) and each frame part, and furthermore can additionally provide soundproofing and windproofing functions.

[0096] The hard member (610) may be made of a relatively hard plastic or metal material. The hard member (610) may be attached to the edge area of ​​the door or fixed with a piece.

[0097] The hard member (610) has an approximate "L" shape, and the adjacent areas of both sides can be connected in a diagonal direction. For example, during the process of attaching the hard member (610), easier attachment can be achieved through these diagonal areas.

[0098] The soft members (620) on both sides may be made of a material such as rubber or silicone that is relatively softer than the hard members (610). The soft members (620) may come into contact with each frame while undergoing elastic deformation of their outer shape during contact. The soft members (620) are arranged diagonally so as to face each other at both ends of the hard members (620), and may be bent in a direction closer to the hard members (610) while coming into contact with each frame during the process of closing the door. At this time, since the soft members (620) can be bent in a diagonal direction or in a curved shape, the contact area with each frame can be increased, and they can also be elastically restored to their original shape as the door opens.

[0099] The cushioning member (600) may additionally be expected to prevent safety accidents caused by contact at the step portion at the edge of the door.

[0112] The protective cover (170) is coupled between the second frame (120) and the coupling frame (160) to cover the inner surface of the second frame (120) and the outer surface of the third frame (130), but can be removed once the installation of the hidden door frame (100'') is completed. The protective cover (170) is made of a synthetic resin material such as rubber or plastic and can prevent damage caused by friction or impact during the installation of the hidden door frame (100''). Between the protective cover (170) and the coupling frame (160), an anti-slip pattern (171) may be provided between the surfaces facing each other. Of course, the protective cover (170) can be coupled so that it can be removed from between the second frame (120) and the coupling frame (160).

[0113] Additionally, the final finishing cover (180) can be joined between the second frame (120) and the connecting frame (160) after the protective cover (170) is removed, and can be joined to the inner surface of the second frame (120) and the front end of the third frame (130). The final finishing cover (180) is made of a steel material such as aluminum and can cover the exterior of the door frame (100'') for the hidden door after the door frame (100'') for the hidden door is installed.

[0114] The final cover (180) may include a first cover plate (181), a second cover plate (182), and a third cover plate (183).

[0115] One end of the first end plate (181) may be inserted between the second frame (120) and the coupling frame (160). On the surfaces where the first end plate (181) and the coupling frame (160) face each other, a slip prevention pattern (184) may be provided to prevent slipping of the first end plate (181) along the longitudinal direction of the coupling frame (160).
