Description

Technical Field

[0001] This invention relates to the field of building construction technology, specifically to a door structure that can be concealed within the surrounding decoration and operates in parallel linkage. Background Technology

[0002] In building exterior decoration and renovation projects, architects often conceal door components to achieve an integrated (hidden) design effect. However, the following problems often arise during construction: After the decorative materials used to conceal metal doors are installed, a certain width (the same as the distance between the finished decorative surface and the metal door) of decorative surface layer needs to be reserved on one side of the metal door hinge to ensure the normal opening of the metal door (opening angle 90°). However, the reserved gap will cause the metal door to fail to achieve the aesthetic effect of integrated design (hidden) with the decorative surface when closed. Summary of the Invention

[0003] To overcome the shortcomings of existing technologies, a parallel linkage door structure that can be hidden within the surrounding decoration is provided to solve the problem that conventional door panels cannot achieve an integrated design with the decorative surface on the outside of the wall when closed, in the case of gaps in the decorative surface layer on the outside of the wall.

[0004] To achieve the above objectives, a parallel linkage door structure that can be concealed within the surrounding decoration is provided, comprising:

[0005] A door frame and a wall have a first door opening. The door frame is embedded in the first door opening. A decorative wall panel is installed on the outside of the wall through a keel. The decorative wall panel has a second door opening, and the position of the second door opening is adapted to the first door opening.

[0006] The interior wall door panel is movably installed in the door frame;

[0007] A decorative door panel is movably installed in the second doorway, and the decorative door panel is arranged opposite to the inner wall door panel;

[0008] Multiple linkage components are provided, each including two opposing leaf plates and a connecting shaft. The two ends of the connecting shaft are respectively hinged to opposite sides of the two leaf plates. The two leaf plates are respectively connected to opposite sides of the inner wall door panel and the decorative door panel. The multiple linkage components are respectively arranged on opposite sides of the width direction of the inner wall door panel. A locking plate is installed on the side of the door frame facing the decorative wall panel. The locking plate is fixedly connected to the connecting shaft of the linkage component on one side of the inner wall door panel. The connecting shaft of the linkage component on one side of the inner wall door panel is arranged along the thickness direction of the inner wall door panel.

[0009] Furthermore, the multiple linkage components are arranged in a matrix.

[0010] Furthermore, the page plate includes two unit plates arranged vertically, one side of each unit plate having a vertically arranged shaft hole, and both ends of the connecting shaft being connected to rotating shafts. The two ends of the rotating shafts are rotatably inserted into the shaft holes of the two unit plates, and the rotating shafts are perpendicular to the connecting shaft.

[0011] Furthermore, a bushing is connected to one side of the unit plate, and the bushing has the shaft hole formed inside.

[0012] Furthermore, the inner diameter of the second door opening gradually increases from the outer side of the decorative door panel to the inner side of the decorative door panel.

[0013] Furthermore, the locking plate is perpendicular to the side of the door frame facing the decorative wall panel. The locking plate is a right-angled triangle with two right-angled sides. One right-angled side is connected to the side of the door frame facing the decorative wall panel, and the other right-angled side is connected to the connecting shaft.

[0014] Furthermore, a notch is formed on the inner side of the connecting shaft of the linkage assembly on the side of the decorative door panel closest to the inner wall door panel, and the locking plate extends into the notch after the decorative door panel is rotated.

[0015] The beneficial effects of this invention lie in its concealable and parallel-linked door structure, where the inner wall door panel and the decorative door panel are connected together by multiple linkage components. During the opening of the inner wall door panel to 90°, the initial state is position A (closed state), the opening process is position B, and the final position is the fully open state. During the opening process, the distance between the inner wall door panel and the decorative door panel gradually decreases until they are flush together. When the inner wall door panel is fully open, the outer side of the decorative door panel abuts against the wall of the second doorway. When the inner wall door panel is closed, the decorative door panel is perfectly embedded in the second doorway, ensuring that the decorative door panel and the decorative wall panel are seamlessly integrated, achieving an aesthetically pleasing effect of concealing the inner wall door panel through a unified design.

[0022] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings.

[0023] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0024] Reference Figures 1 to 5 As shown, the present invention provides a door structure that can be hidden in the surrounding decoration and is linked in parallel, including: door frame 1, inner wall door panel 2, decorative door panel 3, and linkage component 4.

[0025] The wall is an infill wall. A first doorway is formed in wall 5. A door frame 1 is fitted into the first doorway. A decorative wall panel 6 is installed on the outer side of wall 5 via a joist. A decorative surface gap is formed between the decorative wall panel and the wall. A second doorway is formed in decorative wall panel 6. The position of the second doorway matches the first doorway. The shape and size of the second doorway match the shape and size of the first doorway.

[0026] The interior wall door panel 2 is movably installed within the door frame. The decorative door panel 3 is movably installed within the second doorway. The decorative door panel 3 is positioned opposite the interior wall door panel 2. The material of the decorative door panel is the same as that of the decorative wall panel. The dimensions of the decorative door panel are adapted to the dimensions of the second doorway, allowing the decorative door panel to conceal the existence of the first doorway. The dimensions of the decorative door panel are slightly larger than those of the interior wall door panel (due to the presence of the door frame).

[0027] There are multiple linkage components 4. Specifically, linkage component 4 includes two-page plates and connecting shaft 42.

[0028] The two plates are arranged opposite each other. The two ends of the connecting shaft 42 are respectively hinged to the opposite sides of the two plates.

[0029] The two panels are respectively connected to the opposite sides of the inner wall door panel 2 and the decorative door panel 3.

[0030] Multiple linkage components 4 are respectively disposed on opposite sides of the inner wall door panel 2 in the width direction. In a preferred embodiment, the multiple linkage components 4 are arranged in a matrix and disposed between the inner wall door panel and the decorative door panel.

[0031] A locking plate 21 is installed on the side of the door frame 1 facing the decorative wall panel 6. The locking plate 21 is fixedly connected to the connecting shaft of the linkage component 4 on one side of the inner wall door panel 2. The connecting shaft of the linkage component 4 on one side of the inner wall door panel 2 is arranged along the thickness direction of the inner wall door panel 2.

[0032] See Figure 5 The present invention provides a concealable and parallel-linked door structure that integrates with the surrounding decoration. The inner wall door panel and the decorative door panel are connected by multiple linkage components. During the opening process of the inner wall door panel to 90°, the initial state is position A (closed state), the intermediate state is position B, and the final state is fully open. As the inner wall door panel opens, the distance between the inner wall door panel and the decorative door panel gradually decreases until they are flush together. When the inner wall door panel is fully open, the outer side of the decorative door panel rests against the wall of the second doorway. When the inner wall door panel is closed, the decorative door panel is perfectly fitted into the second doorway, ensuring a seamless integration between the decorative door panel and the decorative wall panel, achieving an aesthetically pleasing effect by concealing the inner wall door panel in a unified design.

[0033] In this embodiment, the page plate includes two unit plates 411 arranged vertically. A vertically arranged shaft hole is formed on one side of each unit plate 411. A rotating shaft 413 is connected to both ends of the connecting shaft. The two ends of the rotating shaft 413 are rotatably inserted into the shaft holes of the two unit plates 411. The rotating shaft 413 is perpendicular to the connecting shaft.

[0034] See Figure 3 and Figure 4 As shown, a bushing 412 is connected to one side of the unit plate 411. A shaft hole is formed inside the bushing 412.

[0035] See Figure 1 and Figure 5 As shown, the inner diameter of the second doorway gradually increases from the outer side of the decorative door panel 3 to the inner side of the decorative door panel 3.

[0036] Continue reading Figure 2 and Figure 5 As shown, the locking plate 21 is perpendicular to the side of the door frame 1 facing the decorative wall panel 6. The locking plate 21 is a right-angled triangle. The locking plate 21 has two right-angled sides. One right-angled side is connected to the side of the door frame 1 facing the decorative wall panel 6. The other right-angled side is connected to the connecting shaft.

[0037] In this embodiment, the locking plate is an isosceles right triangle.

[0038] A notch 30 is formed on the inner side of the connecting shaft of the linkage assembly 4 on the side of the decorative door panel 3 closest to the inner wall door panel 2. After the decorative door panel 3 is rotated, the locking plate 21 extends into the notch 30.

[0039] See Figure 1 and Figure 5 Multiple linkage components are arranged in three rows. The first row of linkage components is fixed to one side of the door frame by a locking plate. As the opening / closing angle of the inner wall door panel increases / decreases, the shape of the inner wall door panel and the decorative door panel will change from a rectangle to a parallelogram and finally to a linear shape. During this process, the deformation of the inner wall door panel and the decorative door panel will cause the panel decorative material installed on the outside of the metal door to shift, thereby avoiding the decorative surface on the side of the door hinge, and finally achieving the effect of integrated and hidden design of the decorative surface layer.

[0040] The above description is merely a preferred embodiment of this application and an explanation of the technical principles employed. Those skilled in the art should understand that the scope of the invention involved in this application is not limited to technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the inventive concept. For example, technical solutions formed by substituting the above features with (but not limited to) technical features with similar functions disclosed in this application.
