Description

Technical Field

[0001] The invention relates to the technical field of building curtain wall systems, and in particular to the design of hidden frame doors and windows. Background Art

[0002] Curtain Wall For Building is composed of panels and supporting structure system. It has a certain displacement ability relative to the main structure or a certain deformation ability of itself. It is the outer protective wall of the building that does not bear the effects of the main structure.

[0003] At present, buildings use concealed frame curtain wall systems extensively for aesthetics and design requirements. The development of door and window systems has been relatively mature. According to different design requirements, they have functions such as thermal insulation, heat insulation, sound insulation, waterproofing, and fire prevention. In order to meet the needs of different users, the structure of doors and windows is also constantly being adjusted. Common door and window structures include casement, sliding, and top-hung types.

[0004] For example, a Chinese patent document with publication number CN201320694989.1 discloses a hidden frame frameless swing door system, which includes a curtain wall and an opening sash mounted on the curtain wall through hinges, wherein the opening sash is provided with a sash frame. When the opening sash is closed, the sash frame and the curtain wall form a hidden frame door structure.

[0005] However, this technical solution has certain defects. The hinge is an important component for realizing the rotation and load-bearing of doors and windows. When the hinge is used to connect the door leaf, the door leaf can only realize vertical rotation on the plane relative to the base frame through the motion axis, which makes the rotation trajectory easy to cause interference between components. In addition, the single-axis rotation connection method is used, the structure is simple, the rotation is unstable, and the spatial position of the door leaf is limited. Summary of the invention

[0006] In view of the above problems in the prior art, the present invention provides a connection device and a hidden frame door and window suitable for hidden frame doors and windows, the purpose of which is to achieve more stable rotation, flexible opening and a large rotation range of freedom of the doors and windows through a double-axis rotation connection.

[0007] The above technical purpose of the present invention is achieved through the following technical solutions: a connecting device suitable for hidden frame doors and windows, comprising an inner plate, an outer plate and a frame, the frame comprising frame one and frame two, the outer plate is connected in three sections, including movable plate one, fixed plate and movable plate two, the two ends of the fixed plate are respectively hinged to the movable plate one and the movable plate two, the inner plate is rotatably connected to the fixed plate, the frame one is rotatably connected to one end of the inner plate and one end of the outer plate, and the frame two is rotatably connected to the other end of the inner plate and the other end of the outer plate.

[0008] What is different from the prior art in this case is that the connection device composed of the outer piece and the inner piece rotates more stably, has a greater degree of freedom in the rotation range and rotates more smoothly compared with the ordinary hinge device. The outer piece is divided into a three-section connection. Both ends of the fixed piece are hinged to the first movable piece and the second movable piece respectively. The first movable piece and the second movable piece rotate relative to the fixed piece. The inner piece is arranged inside the outer piece. The inner piece is rotationally connected to the fixed piece. The outer piece and the inner piece are rotationally connected to the frame and need to rotate within the frame. Therefore, a rotating shaft for connecting the outer piece and the inner piece is provided on the frame. One end of the inner piece is rotationally connected to the first frame around the first rotating shaft. One end of the outer piece is rotationally connected to the first frame around the third rotating shaft. The third rotating shaft is inside the first frame. The other end of the inner piece is rotationally connected to the second frame around the second rotating shaft. The other end of the outer piece is rotationally connected to the second frame around the fourth rotating shaft. The fourth rotating shaft is inside the second frame. When the outer piece and the inner piece rotate, the components of the inner piece do not change, while the outer piece is different. There is an opening between the first movable piece and the fixed piece, and there is also an opening between the second movable piece and the fixed piece. Therefore, on the one hand, the first frame is connected to two points, namely the first rotating shaft and the third rotating shaft, and is a double-axis rotation. The second frame is connected to two points, namely the second rotating shaft and the fourth rotating shaft, and is also a double-axis rotation. Both the first frame and the second frame rotate in a double-axis manner, and the connection effect is more stable and the rotation effect is more stable. On the other hand, due to the three-section opening design of the outer piece, the rotation range of the outer piece is larger, which is beneficial to the effective flipping of the second frame.

[0009] As a preference of the present invention, a connection part is provided at the middle position of the fixed piece, and the inner piece is rotationally connected to the connection part.

[0010] Thus, in actual rotation, the user applies the rotation force on the second frame. The second frame moves and drives the corresponding ends of the inner piece and the outer piece to move through the two rotating shafts. The inner piece is of an integral design, and its size and shape do not change during the rotation process. While the outer piece is different. During the rotation process, the angles between the three sections will change. However, in order to further increase the flexibility and smoothness of the rotation process, the inner piece and the connection part can also be rotationally connected through a rotating shaft. Such a structure allows an angular flip between the inner piece and the connection part, so that the flipping action can still be completed even if other components are slightly stuck.

[0011] As a preference of the present invention, the fixed piece includes a first support section and a second support section. The first support section and the second support section are parallel and there is a transition section in the middle. The connection part is on the transition section.

[0012] Thus, the support segment 1 and the support segment 2 are set up in parallel, the support segment 1 is connected to the support segment 2 via a vertical transition segment in the middle, and the connection portion partially overlaps with the transition segment.

[0013] As a preferred embodiment of the present invention, the inner sheet includes a connecting sheet 1 and a connecting sheet 2, and the length of the connecting sheet 1 is longer than that of the connecting sheet 2. The connecting sheet 1 is fixedly connected to the connecting sheet 2 and the connection position corresponds to the connecting portion.

[0014] Thus, the connection position of the same end of the inner plate and the outer plate is on the same retaining edge, the inner plate is adapted to the outer plate, and the angle between the first connecting plate and the second connecting plate remains unchanged.

[0015] As a preferred embodiment of the present invention, both the frame one and the frame two are semi-frame structures, the frame one comprises a side rib one, a side rib two and a side rib three, the two ends of the side rib two are respectively connected to the side rib one and the side rib three and the side rib one and the side rib three are parallel to each other, the frame one wraps part of the inner sheet and part of the outer sheet, and the side rib three is rotatably connected to one end of the inner sheet and the outer sheet; the frame two comprises a side rib four, a side rib five and a side rib six, the two ends of the side rib five are respectively connected to the side rib four and the side rib six and the side rib four and the side rib six are parallel to each other, the frame two wraps part of the inner sheet and part of the outer sheet, and the side rib six is ​​rotatably connected to the other end of the inner sheet and the outer sheet.

[0016] Therefore, the frame 1 and the frame 2 respectively have the effect of hiding part of the outer sheet and part of the inner sheet.

[0017] A hidden frame door and window system comprises a base and a rotating member, and a connecting device suitable for hidden frame doors and windows installed between the base and the rotating member, wherein the rotating member is connected to the second frame, and the base is connected to the first frame.

[0018] Thus, the rotating member can be flipped relative to the base by flipping the frame 2 relative to the frame 1, thereby achieving a more stable rotation and greater rotation freedom of a casement door system such as doors and windows.

[0019] As a preferred embodiment of the present invention, it also includes a cover plate for covering the frame 1.

[0020] Thus, the cover plate is connected to the retaining edge and together with the frame, serves to shield the frame.

[0021] As a preferred embodiment of the present invention, the rotating member is a curtain wall or a glass window.

[0022] Thereby, flexible rotation of the building curtain wall or window and the overall hidden frame effect are achieved.

[0023] In summary, the present invention has the following beneficial effects:

[0024] 1. The rotation of the double-axis rotating connector composed of the outer piece and the inner piece is more stable and has a greater degree of rotational freedom;

[0025] 2. The establishment of the frame has the effect of hiding the outer piece and the inner piece, achieving the overall hidden frame effect of the building curtain wall and enhancing the visual integrity;

[0026] 3. The connection device will not have the situation of asymmetry between the two page blocks, improving the installation efficiency of the connection device between the base frame and the rotating member and reducing the labor intensity. BRIEF DESCRIPTION OF THE DRAWINGS

Therefore, it should not be construed as a limitation to the present invention.

[0036] Embodiment 1, a connecting device applicable to hidden frame doors and windows. The connecting device includes an inner piece 1, an outer piece 2, and a frame 3. The frame 3 includes a first frame 31 and a second frame 32. The first frame 31 and the second frame 32 are two semi-frame-shaped frames with similar structures. The outer piece 2 is a three-section connection, including a movable piece one 21, a fixed piece 22, and a movable piece two 23. Both ends of the fixed piece 22 are hinged to the movable piece one 21 and the movable piece two 23 respectively. The first frame 31 is rotatably connected to one end of the inner piece 1 and one end of the outer piece 2, and the second frame 32 is rotatably connected to the other end of the inner piece 1 and the other end of the outer piece 2.

[0037] As Figure 1 shown, it is a schematic cross-sectional view of the closed structure of the connecting device. When the connecting device is closed, the inner piece 1 is arranged inside the outer piece 2. The inner piece 1 includes a connecting piece one 11 and a connecting piece two 12. The inner piece 1 is rotatably connected to the connecting part e and the shape and size of the inner piece 1 remain unchanged. The length of the connecting piece one 11 is longer than that of the connecting piece two 12 because the connection positions of the inner piece 1 and the outer piece 2 at the same end are on the same retaining edge, and the inner piece 1 adapts to the outer piece 2. Among them, the fixed piece 22 includes a support section one 221 and a support section two 222 arranged in parallel. The support section one 221 is connected to the support section two 222 through a vertical transition section 223 in the middle. The setting of the vertical transition section 223 causes a height difference between the movable piece one 21 and the movable piece two 23, and further causes a height difference between the first frame 31 and the second frame 32.

[0038] The first frame 31 and the second frame 32 connect the outer piece 2 and the inner piece 1. A retaining edge one 311, a retaining edge two 312, and a retaining edge three 313 wrap part of the outer piece 2 and part of the inner piece 1. One end of the outer piece 2 is connected to the retaining edge three 313 through a rotating shaft three c, and one end of the inner piece 1 is connected to the retaining edge three 313 through a rotating shaft one a. Among them, the rotating shaft three c is inside the first frame 31; a retaining edge four 321, a retaining edge five 322, and a retaining edge six 323 wrap part of the outer piece 2 and part of the inner piece 1. The other end of the outer piece 2 is connected to the retaining edge six 323 through a rotating shaft four d, and the other end of the inner piece 1 is connected to the retaining edge six 323 through a rotating shaft two b. Among them, the rotating shaft four d is inside the second frame 32.

[0039] As Figure 2As shown in the figure, it is a schematic cross-sectional view of the opening structure of the connecting device. The first frame 31 is fixed. When the second frame 32 is pulled, the moving direction of the second frame 32 is the same as the direction of the pulling force. The outer sheet 2 drives the inner sheet 1 to rotate. The components of the inner sheet 1 do not change, while the outer sheet 2 is different. There is an opening between the first movable sheet 21 and the fixed sheet 22, and there is also an opening between the second movable sheet 23 and the fixed sheet 22. The second frame 32 rotates around the second rotating shaft b and the fourth rotating shaft d and is rotationally connected to the outer sheet 2 and the inner sheet 1 to realize the flipping relative to the first frame 31. The first frame 31 is rotationally connected to the outer sheet 2 and the inner sheet 1 through the first rotating shaft a and the third rotating shaft c. The double-axis connection makes the rotation more stable. In addition, due to the three-section opening design of the outer sheet, the rotation range of the outer sheet is larger, which is beneficial to the effective flipping of the second frame.

[0040] As Figure 3 shown, a hidden frame door and window is provided on a glass curtain wall, which includes a base, an opening fan, and the above-mentioned connecting device applicable to the hidden frame door and window. In this embodiment, the base is a decorative cover plate 4 for connecting the first frame 31, and the opening fan is connected to the second frame 32 to realize the rotation of the opening fan relative to the decorative cover plate 4.

The decorative cover plate 4 includes a first hidden cover plate 41 for covering the first edge 311 and a second hidden cover plate 42 for covering the third edge 313. Therefore, the second frame 31 is hidden in the decorative cover plate. The opening fan is composed of a door panel and a fan frame 5 connected to the periphery of the door panel. The second frame 32 is connected to the opening fan through the fan frame 5. The fan frame 5 includes a first fan frame 51 for covering the fourth edge 321 and a second fan frame 52 for covering the sixth edge 323. The second fan frame 52 is connected to a fixing plate 7 for covering the second fan frame 52 through structural glue. A hidden edge 6 corresponding to the fixing plate 7 is also fixedly connected to the decorative cover plate 4. The hidden edge 6 is used to cover the first fan frame 51. Similarly, the first hidden piece 111 provided on the first connecting piece 11 also plays a role in covering the side of the first frame 31 close to the second frame 32. Finally, the effect of the overall hidden frame is achieved.

[0041] As Figure 4 shown, it is the state where the opening fan rotates relative to the decorative cover plate 4 and is in an open state. Due to the overall hiding of the decorative cover plate 4, the hidden edge 6, the first hidden piece 111, and the fixing plate 7 for the connected device inserted, when opening, the effect of the overall hidden frame is also achieved, increasing the appearance beauty of the glass curtain wall.
