DETAILED DESCRIPTION

[0032] In order to make the purpose, technical scheme and advantages of the embodiments of the present disclosure clearer, the technical scheme of the embodiments of the present disclosure will be described clearly and completely below in conjunction with the drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, rather than all the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by a person of ordinary skill in the art without any inventive effort fall within the scope of protection of the present disclosure.

[0033] Please refer to Figures 1-8 The embodiment of the present application provides a kind of compound window system of retro style, including main body 1 and the window body 2 on main body 1, window body 2 one side is provided with openwork carving, further include: frame 3, it is set in window body 2 another side, glass is installed on it;Rocker arm 4, it is symmetrically set a pair of up and down, one end is hinged with the inner side of window body 2, the other end is hinged with the upper and lower end middle part of frame 3 near, by the rotation function of the two ends of rocker arm 4, make frame 3 have the first position of being stored in window body 2 and being attached to carving and the second position of being removed from window body 2 and being spaced apart;Butt joint component, it is set in frame 3, for limiting frame 3 in the position close to window body 2.

[0034] Specifically, the main body 1 is primarily made of wood and is rectangular in shape. The window 2 is a rectangular opening in the upper half of the main body 1, meaning the portion of the main body 1 containing the window 2 is frame-shaped. The frame 3's shape matches the rectangle formed by the inner walls of the window 2. The frame 3 can be embedded within the window 2 and covers the area of ​​the carved portion. The vertical sidewalls of the frame 3 have rounded corners or gaps between them and the inner walls of the window 2 to facilitate the frame 3's movement in and out of the window 2. The rocker arms 4 swing horizontally, and the frame 3 is connected between two rocker arms 4. The first position of the frame 3 is when it is parallel and retracted within the window 2. Furthermore, the frame 3 is designed to fit the carved surface. In the second position, the rocker arm 4 swings out of the window 2. At the same time, the frame 3 rotates at the end of the rocker arm 4 to create a certain gap between the frame 3 and the window 2. The process of switching the frame 3 from the first position to the second position is as follows: the rocker arm 4 and the frame 3 move and rotate first, so that one side of the frame 3 leaves the window 2. Then, the frame 3 rotates relative to the rocker arm 4 so that the other side also leaves the window 2. Thus, the frame 3 is separated from the window 2. The docking component limits the frame 3, which helps the frame 3 to remain in the first position and prevents the frame 3 from moving freely. In practical use, when both frame 3 and rocker arm 4 are inside window 2, the docking component can limit frame 3, thus maintaining frame 3 in the first position, allowing frame 3 to fit the carved surface normally. When cleaning the glass is required, the docking component first releases the limit on frame 3, and then the rocker arm 4 rotates outward from window 2, and frame 3 rotates at the end of rocker arm 4 to reach the second position. At this time, window 2 and frame 3 are separated, which not only facilitates cleaning both sides of the glass, but also ensures that the glass and the main body 1 are separated in dry and wet during the cleaning process, thereby extending the service life of the wooden part of the main body 1.

[0035] Compared with the prior art, the retro-style composite window system proposed in this embodiment of the invention, by setting a rocker arm 4, allows the frame 3 of the installed glass to be in a first position to fit the carving during normal use, and the docking component can limit the frame 3 at this time. When the glass needs to be cleaned, the rocker arm 4 rotates outward from the window body 2, and the frame 3 rotates at the end of the rocker arm 4 to reach a second position. At this time, the window body 2 and the frame 3 are separated. Therefore, it is not only convenient to clean both sides of the glass, but also to ensure that the glass and the main body 1 are separated in dry and wet during the cleaning process, thereby extending the service life of the wooden part of the main body 1.

[0036] As the preferred technical scheme of the embodiment, the rocker arm 4 is provided with a first shaft rod 5 at one end, and the inner top surface and the inner bottom surface of the window body 2 are provided with first rotary grooves 6 corresponding to each other and matched with the first shaft rod 5. Specifically, the first shaft rod 5 of the upper rocker arm 4 is arranged at the upper side thereof and matched with the first rotary groove 6 of the inner top surface of the window body 2, and the first shaft rod 5 of the lower rocker arm 4 is arranged at the lower side thereof and matched with the first rotary groove 6 of the inner bottom surface of the window body 2. The first rotary groove 6 is arranged close to the inner side wall of the window body 2. Thus, when the rocker arm 4 is transmitted to about 90° outside the window body 2, the rocker arm 4 can be positioned reliably against the inner side wall of the window body 2.

[0037] As the preferred technical scheme of the embodiment, the rocker arm 4 is provided with a second shaft rod 7 at the other end, and the upper end and the lower end of the frame 3 are provided with second rotary grooves 8 matched with the second shaft rod 7. Specifically, the second shaft rod 7 of the upper rocker arm 4 is arranged at the lower side thereof and away from the first shaft rod 5 at one end, and the second shaft rod 7 of the lower rocker arm 4 is arranged at the upper side thereof and away from the first shaft rod 5 at one end. The second rotary grooves 8 arranged at the upper end and the lower end of the frame 3 are vertically coaxial. The second rotary grooves 8 are arranged close to the middle part of the frame 3. Thus, when the frame 3 is in the second position, the end part of the rocker arm 4 can be suspended more stably.

[0038] In another embodiment of the present application, the second rotating slot 8 is provided with a positioning slot 9, and the end of the second shaft 7 is provided with a positioning block 10 which is elastically telescopic. The frame 3 is rotated at a certain angle relative to the rocker 4 in the second position to make the positioning slot 9 correspondingly clamped with the positioning block 10. Specifically, when cleaning the glass on the frame 3, the frame 3 needs to be stopped from rotating. The embodiment is proposed to solve this problem. The positioning slot 9 is only provided in the lower second rotating slot 8, which is convenient for operation. Correspondingly, the lower second shaft 7 is provided with a spring slot, and the positioning block 10 is connected in the spring slot through a spring. The spring keeps pushing the positioning block 10 close to the positioning slot 9. When the frame 3 is in the first position, the rotation angle difference between the positioning slot 9 and the positioning block 10 is 90°. When the frame 3 is in the second position, the positioning slot 9 corresponds to the positioning block 10, and the positioning block 10 is automatically embedded in the positioning slot 9 under the spring pushing force. The end of the positioning block 10 away from the positioning slot 9 is fixedly provided with a pull rod 22, and the lower side of the lower rocker 4 is provided with a groove. The lower end of the pull rod 22 is movably penetrated through the rocker 4 and extends into the groove. When the positioning block 10 is pushed by the spring, the lower end of the pull rod 22 does not exceed the range of the groove. In actual use, when the frame 3 is switched from the first position to the second position, the frame 3 is first rotated together with the rocker 4 outwardly of the window 2. The side of the frame 3 provided with the docking assembly first leaves the window 2. After the rocker 4 is rotated by 90° to lean against the inner side wall of the window 2, the frame 3 is further pushed to continue to rotate relative to the rocker 4. Thus, the second shaft 7 is rotated relative to the second rotating slot 8. After the frame 3 is rotated by 90° relative to the rocker 4, the frame 3 is entirely parallel to the window 2, and a gap is formed between the frame 3 and the window 2. At the same time, the positioning block 10 corresponds to the positioning slot 9, and the positioning block 10 can be automatically embedded in the positioning slot 9 under the elastic pushing force to limit the rotation between the second rotating slot 8 and the second shaft 7. Thus, the glass on the frame 3 is conveniently cleaned. Subsequently, when the frame 3 is switched from the second position to the first position, the pull rod 22 can be first pulled downwardly. The pull rod 22 drives the positioning block 10 to descend against the elastic force. After the positioning block 10 leaves the positioning slot 9, the frame 3 is further pushed to rotate. Thus, the positioning block 10 is misaligned with the positioning slot 9 to limit the relative position. Then, the frame 3 is pushed together with the rocker 4 back into the window 2, that is, the frame 3 is reset to the first position.

[0039] In another embodiment of the present application, the docking assembly comprises a rotating sleeve 11 rotatably arranged inside the upper and lower ends of the frame 3, the rotating sleeve 11 is screw transmission connected with a lifting block 12, one end of the lifting block 12 is movably penetrated through the frame 3 and is provided with a docking groove 13, the inner top surface and the inner bottom surface of the frame 3 are provided with a docking shaft 14 matched with the docking groove 13, and a sliding rod 15 is movably arranged in the frame 3, one end of the sliding rod 15 is screw transmission connected with a rotating rod 16, the rotating rod 16 is transmission connected with the rotating sleeve 11 through bevel gear transmission, specifically, the docking assembly is preferably two groups arranged symmetrically and close to one vertical side of the frame 3; the rotating sleeve 11 is vertically axial; the lifting block 12 comprises a transmission part directly screw connected with the rotating sleeve 11 and a docking part for setting the docking groove 13 to cooperate with the docking shaft 14; the outer wall of the transmission part is provided with a sliding convex, the inner wall of the rotating sleeve 11 is provided with a spiral groove, the sliding convex is slidingly connected with the spiral groove to form a screw transmission relationship; the docking part is provided in a multi-prism shape and movably penetrates through the frame 3 to only perform lifting movement, so that the transmission part and the rotating sleeve 11 driven to rotate play a screw feed transmission function; the docking shaft 14 is preferably cylindrical and the end is provided with a round or chamfered corner, and the inner wall of the opening of the docking groove 13 is also provided with a round or chamfered corner; the sliding rod 15 moves horizontally between the second rotating groove 8 and the rotating sleeve 11, and the end of the sliding rod 15 close to the rotating sleeve 11 is provided with a cylindrical hole along the extension direction thereof, the inner wall of the cylindrical hole is provided with another spiral groove, the outer wall of the rotating rod 16 is provided with a spiral wire matched with the spiral groove, the sliding rod 15 only performs horizontal sliding, so that the rotating rod 16 rotates under the screw transmission action, and the end of the rotating rod 16 away from the sliding rod 15 is coaxially connected with a first bevel gear, and the outer wall of the rotating sleeve 11 is fixedly sleeved with a second bevel gear meshing with the first bevel gear. In actual use, when the frame 3 is in the first position and the sliding rod 15 moves towards the rotating sleeve 11, the rotating rod 16 is linked to rotate under the screw transmission action, the rotating sleeve 11 is linked to rotate, and the rotating sleeve 11 forces the lifting block 12 to rise under the screw feed transmission action, the lifting block 12 drives the docking groove 13 to correspondingly insert with the docking shaft 14, so that the frame 3 can be limited to be in the window body 2, and when the sliding rod 15 moves reversely, the same transmission process as above is performed, but the lifting block 12 drives the docking groove 13 to descend to disengage from the docking shaft 14.

[0040] As a preferred technical solution of the present embodiment, a first handle 17 is arranged outside the frame 3, the upper and lower ends of the first handle 17 movably penetrate through the side wall of the frame 3 and are respectively fixedly connected with the sliding rods 15 of the upper and lower docking assemblies, specifically, the first handle 17 can synchronously operate the two sliding rods 15 to move.

[0041] In another embodiment of the present application, the second rotating groove 8 extends in a strip shape on one side away from the direction of the docking assembly, and the second shaft 7 can slide in the second rotating groove 8. When the docking assembly limits one side of the frame 3, the sliding function of the second shaft 7 can make the frame 3 have a third position in which the un-limited side is horizontally opened. Specifically, when the docking assembly keeps limiting one side of the frame 3, the sliding function of the second shaft 7 in the second rotating groove 8 can make the rotation of the rocker 4 around the axis of the first shaft 5 and the rotation of the frame 3 around the axis of the docking shaft 14 occur simultaneously, and the second shaft 7 slides in the second rotating groove 8 to make the rotation of the rocker 4 and the rotation of the frame 3 not interfere with each other, thereby realizing the opening and closing function of one side of the frame 3.

[0042] As a preferred technical solution of the present embodiment, the side wall of the second rotating groove 8 is provided with a limiting assembly for limiting the second shaft 7. When the docking groove 13 is inserted with the docking shaft 14, the limiting assembly cancels the limitation. Specifically, the sliding function of the second shaft 7 in the second rotating groove 8 can affect the stability of the frame 3 in the second position. The limiting assembly can limit the second shaft 7 in the second rotating groove 8 near one end close to the docking assembly. At this time, the position of the second shaft 7 relative to the frame 3 is fixed and kept near the middle part of the frame 3, and at this time, the docking assembly cancels the limitation of the frame 3. Thus, the frame 3 can be switched to the second position and stably suspended at the end of the rocker 4, and the clamping function of the positioning block 10 and the positioning groove 9 can also be smoothly realized. When the docking assembly limits the frame 3, i.e. the docking groove 13 is inserted with the docking shaft 14, the limiting assembly can also cancel the limitation, i.e. does not affect the switching function of the frame 3 to the third position.

[0043] As a preferred technical scheme of the embodiment, the limiting assembly comprises a movable slot 18 arranged on one side of the second rotating slot 8, a limiting piece 19 elastically arranged in the movable slot 18 and capable of rotating, one end of the limiting piece 19 being inwardly bent and used for clamping the second shaft 7 in the second rotating slot 8 close to one end of the sliding rod 15, and the other end of the limiting piece 19 being provided with an abutting block 20, one end of the sliding rod 15 away from the rotating rod 16 being wedge-shapedly arranged with the abutting block 20, specifically, the movable slot 18 is in a U shape and is arranged on the outer side of one end of the second rotating slot 8 close to the docking assembly, the rotating shaft of the limiting piece 19 is arranged at the middle position and vertically, and a torsion spring is arranged on the side of the limiting piece 19 away from the second rotating slot 8 to connect the inner wall of the movable slot 18, the force point of the torsion spring being arranged on the abutting block 20, so that the bent end of the limiting piece 19 keeps away from the second rotating slot 8, and the limiting piece 19 is preferably two and symmetrically arranged, and can be in a pincer shape, the sliding rod 15 is moved close to the second rotating slot 8 to make the end part extruded between the two abutting blocks 20 of the limiting pieces 19, so that the bent end of the limiting piece 19 is close to each other to clamp the second shaft 7 in the second rotating slot 8 close to the docking assembly, that is, the second shaft 7 is limited to be at this end, when the sliding rod 15 is at the position closest to the second rotating slot 8, the two limiting pieces 19 can clamp the second shaft 7, and the position of the other end of the sliding rod 15 corresponds to the disengagement of the docking slot 13 and the docking shaft 14. Further, when the sliding rod 15 is moved close to the second rotating slot 8 and the docking slot 13 is linked to be lowered without being completely disengaged from the docking shaft 14, the sliding rod 15 can be extruded between the two abutting blocks 20, so that the clamping action of the two limiting pieces 19 on the second shaft 7 can be triggered, when the frame 3 is at the first position, the sliding rod 15 at this position can simultaneously satisfy the insertion of the docking slot 13 and the docking shaft 14 and the clamping of the limiting piece 19 on the second shaft 7, so that the frame 3 can be completely limited at the first position, that is, corresponding to the fixed closure of the window body 2, further, three positions are marked in the moving track of the second handle 21 on the frame 3 to correspond to the three states of the sliding rod 15, that is, the sliding rod 15 is moved to one end away from the second rotating slot 8, at this time, the docking slot 13 and the docking shaft 14 are most deeply inserted, the limiting piece 19 does not form the clamping on the second shaft 7, so that the frame 3 can be switched between the first position and the third position, when the sliding rod 15 is moved to one end close to the second rotating slot 8, at this time, the docking slot 13 and the docking shaft 14 are separated, the limiting piece 19 can clamp the second shaft 7, so that the frame 3 can be switched between the first position and the second position, when the sliding rod 15 is moved to the middle position of the moving stroke, the docking slot 13 and the docking shaft 14 are not completely separated, the sliding rod 15 can still be extruded between the two abutting blocks 20 to trigger the clamping of the limiting piece 19 on the second shaft 7, so that the frame 3 is locked at the first position. The sliding of the sliding rod 15 has damping, and it can be stationary at any position when it is not subjected to external force, and it is only controlled by the first handle 17.

[0044] As a preferred technical solution of the embodiment, a second handle 21 is arranged on the side of the frame 3 away from the docking assembly, and in particular, the second handle 21 is used to operate the frame 3 to switch between the first position and the third position.

[0045] The above merely describes certain exemplary embodiments of the present application by way of illustration, and it is needless to say that those skilled in the art can modify the described embodiments in various manners without departing from the spirit and scope of the present application. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present application.
