Description

Technical Field

[0001] This invention relates to the field of building decoration technology, and more specifically, to a door assembly, a wall concealed door assembly, and an installation method thereof. Background Technology

[0002] Concealed doors are a popular interior design technique that can enhance the visual appeal of a space. The key to a concealed door is its invisibility; it hides the door within the decor, hence the name "hidden door." A concealed door design not only hides the door itself but also the space, serving as a finishing touch to the overall interior design.

[0003] Currently, the construction of concealed wall doors is complex, involving numerous steps and making factory prefabrication impossible. It also demands high worker skill levels, failing to meet the needs of skilled industrial workers for easy installation. Once installed, concealed doors are not removable, are prone to deformation after a period of use, and are difficult to maintain, requiring complete replacement and generating significant construction waste. The common practice for concealed wall door decoration in the market is a "steel frame + surface panel," but the surface panels are often very thin, and the steel frame is exposed, resulting in a hollow feel and affecting the decorative effect. Furthermore, the edges of prefabricated concealed wall doors are exposed and cannot be concealed, leading to poor aesthetics. Summary of the Invention

[0004] The purpose of this invention is to provide a door assembly, a wall concealed door assembly, and an installation method thereof, so as to solve the technical problems of wall concealed doors in the prior art, such as complex construction, non-removable and non-replaceable, easy deformation, strong hollow feeling, and poor aesthetics of exposed edges.

[0036] Figure 1 This is a cross-sectional structural diagram of a door assembly provided in an embodiment of the present invention. Figure 1 As shown in the figure, this application embodiment provides a door assembly, including: door 10, first edge trimming assembly 20 and second edge trimming assembly 30.

[0037] The first edge-finishing assembly 20 includes a detachably connected inverted edge-finishing clip 21 and a slotted edge-finishing clip 22. The inverted edge-finishing clip 21 is fixed to one side of the door body 10, and the slotted edge-finishing clip 22 is fixed to the wall. Both the inverted edge-finishing clip 21 and the slotted edge-finishing clip 22 are provided with supporting protrusions 23 for fixing to the door body 10 or to the wall. It should be noted that the inverted edge-finishing clip 21 and the slotted edge-finishing clip 22 can be integrally molded, or they can be manufactured by welding or other manufacturing methods.

[0038] Figure 2 This is a cross-sectional structural diagram of a telescopic edge handle in a door assembly in the extended state, provided as an embodiment of the present invention. Figure 2 As shown, the inverted edge-trimming clip 21 includes a first clip body 211, a telescopic edge-trimming handle 212, and a sliding fixing screw 213. The telescopic edge-trimming handle 212 is slidably connected to the first clip body 211 through the sliding fixing screw 213.

[0039] The inverted edge trimming clip 21 and the telescopic edge trimming handle 212 are connected by a sliding fixing screw 213 to form a sliding relationship. The telescopic edge trimming handle 212 can be pulled out as needed, eliminating the need for surface-mounted handles or latches on the door panel. This allows for flexible use while balancing aesthetics and practicality.

[0040] Figure 3 This is a schematic cross-sectional view of the first edge-receiving assembly provided in an embodiment of the present invention. Figure 3As shown, the insertion edge trimming clip 22 includes a U-shaped groove 221, and a rubber sleeve 222 is provided inside the U-shaped groove 221. The inverted edge trimming clip 21 includes an inverted strip 214, which is inserted into the rubber sleeve 222 of the U-shaped groove 221 when the inverted edge trimming clip 21 and the insertion edge trimming clip 22 are connected.

[0041] In one example, the rubber sleeve 222 provided in the U-shaped groove 221 of the insertion edge retainer 22 includes a first rubber strip and a second rubber strip. The first rubber strip and the second rubber strip are respectively provided on both sides of the U-shaped groove 221 to form a double-sided rubber sleeve 222. An elastic slot for fixing the inverted insert 214 is formed between the first rubber strip and the second rubber strip. When the inverted insert 214 is inserted into the elastic slot, the double-sided rubber sleeve 222 shrinks and squeezes, so that the door 10 is firmly closed and not easy to shake or pop open.

[0042] It is understood that this embodiment does not require the installation of a door lock. The double-sided rubber sleeves 222 are used to fix the inverted strip 214, forming a locking structure. This structure is simple, low-cost, and highly practical. Furthermore, the double-sided rubber sleeves 222 can effectively reduce the noise generated by the collision of metal components when the door 10 is closed, making it safe and environmentally friendly.

[0043] In one example, the end of the inverted insert 214 inserted into the U-shaped slot 221 is provided with an arc angle. The purpose is to make the inverted insert 214 and the U-shaped slot 221 fit together smoothly and easily, and also to reduce the wear of the rubber sleeve 222 and improve its service life.

[0044] Both the inverted edge trimming clip 21 and the slot edge trimming clip 22 are fixed to the door 10 or the wall by self-tapping screws 16. Both the inverted edge trimming clip 21 and the slot edge trimming clip 22 are provided with countersunk screw grooves 18 to hide the heads of the self-tapping screws 16.

[0045] Specifically, countersunk screw lines 17 are provided at the positions where self-tapping screws 16 are installed on the inverted edge trimming clip 21 and the socket edge trimming clip 22. Countersunk screw grooves 18 are provided on the plane where the countersunk screw lines 17 are located. After the self-tapping screws 16 are assembled, the heads of the self-tapping screws 16 are located in the countersunk screw grooves 18, which ensures the flatness of the exposed surfaces of the inverted edge trimming clip 21 and the socket edge trimming clip 22 and has good aesthetics.

[0046] In addition, both the inverted edge-trimming clip 21 and the slotted edge-trimming clip 22 are provided with supporting protrusions 23 for fixing to the door body 10 or the wall. The supporting protrusions 23 can ensure the stability of the inverted edge-trimming clip 21 and the slotted edge-trimming clip 22 fixed to the door body 10 or the wall, with even force distribution and less wobbling, thereby effectively suppressing deformation and improving service life.

[0047] Please see Figure 1The door 10 includes a first door panel 11 and a second door panel 12 arranged in parallel, with sound insulation cotton 13 filling the space between the first door panel 11 and the second door panel 12. Unlike the existing technology of "steel frame + surface panel", this application uses a combination of two door panels and fills the space between the two door panels with sound insulation cotton 13. The overall structure is compact, meets the structural strength requirements of the door 10, and effectively reduces the hollow feeling of the door 10.

[0048] The door body 10 also includes an H-shaped top and bottom hinge 14 and multiple fixing plates 15. The H-shaped top and bottom hinge 14 is located at the top of the door body 10, allowing the door body 10 to rotate around the axis of the H-shaped top and bottom hinge 14. Multiple fixing plates 15 are fixedly disposed at intervals on multiple sides of the first door panel 11 and the second door panel 12, so that the positions of the first door panel 11, the second door panel 12, and the sound insulation cotton 13 are relatively fixed. For the structural features of the H-shaped top and bottom hinge 14, please refer to [reference needed]. Figure 5 .

[0049] In one possible embodiment, the multiple fixing pieces 15 are four-corner fixing pieces, which are respectively fixed at the four top corners of the door body 10 for fixing the door body 10. Specifically, the two sides of the fixing pieces 15 can be fixedly connected to the first door panel 11 and the second door panel 12 by screws respectively. After the multiple fixing pieces 15 are fixedly connected to the first door panel 11 and the second door panel 12, the first door panel 11, the second door panel 12 and the sound insulation cotton 13 can be fixed to form a whole, that is, the door body 10.

[0050] It is understood that the number of fixing pieces 15 and their positions on the side of the door 10 can be set as needed, and the distribution and spacing of the fixing pieces 15 can also be set according to the actual situation. This application does not impose specific limitations. The sound insulation cotton 13 and the H-shaped top and bottom hinges 14 can be flexibly adjusted in terms of their relative positions and proportions according to the width of the door panel to adjust the opening angle of the door 10.

[0051] In one embodiment, when the door assembly 1 is closed, a U-shaped groove is formed between the inverted edge trimming clip 21 and the insertion edge trimming clip 22. The groove is 5mm wide, meaning the gap between the inverted edge trimming clip 21 and the insertion edge trimming clip 22 is 5mm. This U-shaped groove forms the exposed edge of the door assembly 1, which can enhance the sense of layering of the door 10 and the wall surface, making it exquisite, beautiful, and decorative.

[0052] Figure 4 This is a cross-sectional structural diagram of the second edge-receiving component provided in an embodiment of the present invention. Figure 4As shown, the second edge-finishing assembly 30 includes a detachably connected C-shaped edge-finishing clip 31 and an anti-collision edge-finishing clip 32. The anti-collision edge-finishing clip 32 is disposed opposite to the inverted edge-finishing clip 21 on the other side of the door body 10. The C-shaped edge-finishing clip 31 is fixed to the wall. Both the C-shaped edge-finishing clip 31 and the anti-collision edge-finishing clip 32 are provided with supporting protrusions 23 for fixing to the door body 10 or to the wall. It should be noted that the C-shaped edge-finishing clip 31 and the anti-collision edge-finishing clip 32 can be integrally molded, welded, or processed by other methods.

[0053] In one possible embodiment, a limiting block 321 is provided on the anti-collision edge trimming clip 32, and the limiting block 321 is movably connected to the C-shaped edge trimming clip 31. A rubber bumper 322 is provided at the contact point between the limiting block 321 and the C-shaped edge trimming clip 31 for cushioning.

[0054] Specifically, the limiting block 321 is fixedly mounted on the anti-collision edge trimming bracket 32, which is fixed to the door body 10. The C-shaped edge trimming bracket 31 is fixed to the wall. When the door body 10 is in the closed state, the limiting block 321 contacts the edge of the C-shaped edge trimming bracket 31. To prevent the door body 10 from being over-closed, the limiting block 321 is provided on the anti-collision edge trimming bracket 32 ​​to limit the position of the door body 10 when closed, thus avoiding excessive opening or closing.

[0055] To avoid rigid contact, an adhesive pad 322 is provided at the contact point between the limiting block 321 and the C-shaped edge-receiving clip 31 to serve as a buffer. The thickness of the adhesive pad 322 can be set according to the actual situation.

[0056] Both the C-type edge trimming clip 31 and the anti-collision edge trimming clip 32 are fixed to the door 10 or the wall by self-tapping screws 16. Both the C-type edge trimming clip 31 and the anti-collision edge trimming clip 32 are provided with countersunk screw grooves 18 to hide the heads of the self-tapping screws 16.

[0057] Specifically, countersunk screw lines 17 are provided at the positions where self-tapping screws 16 are installed on the C-type edge trimming clip 31 and the anti-collision edge trimming clip 32. Countersunk screw grooves 18 are provided on the plane where the countersunk screw lines 17 are located. After the self-tapping screws 16 are assembled, the heads of the self-tapping screws 16 are located in the countersunk screw grooves 18, ensuring the flatness of the exposed surfaces of the C-type edge trimming clip 31 and the anti-collision edge trimming clip 32, and providing good aesthetics.

[0058] In addition, both the C-shaped edge trimming clip 31 and the anti-collision edge trimming clip 32 are provided with support protrusions 23 for fixing to the door body 10 or the wall. The support protrusions 23 can ensure the stability of the C-shaped edge trimming clip 31 and the anti-collision edge trimming clip 32 when fixed to the door body 10 or the wall, so that the force is evenly distributed and it is not easy to shake, thereby effectively suppressing deformation and improving service life.

[0059] In one possible embodiment, the first edge-sealing assembly 20 and the second edge-sealing assembly 30 are symmetrically arranged on both sides of the door body 10.

[0060] In this embodiment, a telescopic edge-finishing handle 212 is provided on the first edge-finishing assembly 20. It can be extended and retracted on the first edge-finishing assembly 20 via a sliding fixing screw 213, forming a pull-out concealed handle that is both aesthetically pleasing and practical, conforming to the design of a concealed door. The inverted strip 214 on the retainer can be directly inserted into the U-shaped slot 221 on the edge-finishing retainer 22. The inverted strip 214 is fixed by the rubber sleeve 222 in the slot, allowing the door to close tightly without magnetic or other locking mechanisms. The rubber sleeve 222 also protects the door from damage when closing with excessive force and prevents noise. The U-shaped groove formed by the first edge-finishing assembly 20 and the second edge-finishing assembly 30 is only 5mm, complementing the decorative wall surface for a beautiful and refined look. The sound-insulating cotton 13 filling the door body 10 effectively reduces the hollow feeling, improving the user experience.

[0061] Figure 6 This is a cross-sectional structural diagram of a concealed wall door assembly provided in an embodiment of the present invention. Figure 6 As shown in the illustration, this application also provides a wall-mounted concealed door assembly, including a wall assembly 4 and a door assembly 1 as described above. The wall assembly 4 is fixed to the wall and connected to the door assembly 1. It should be noted that when the concealed door assembly is in the closed state, the exposed surface of the wall assembly 4 and the exposed surface of the door assembly 1 are on the same plane to ensure the decorative and aesthetic appearance of the wall-mounted concealed door assembly.

[0062] In one possible embodiment, the wall assembly 4 includes a decorative panel 41, a leveling joist 42, and leveling bolts 43. The decorative panel 41 is disposed on both sides of the door assembly 1, and the decorative panel 41 and the door 10 are on the same horizontal plane.
