Detailed Description

The following are embodiments of the present invention and the accompanying drawings are used to further describe the technical solutions of the present invention, but the present invention is not limited to these embodiments.

An assembled folding window with adjustable corners is shown in figure 1 and comprises two parallel fixing frames 1 and a plurality of window bodies 2 arranged between the two fixing frames 1.

During actual installation, two mounts 1 are usually respectively through screw fixed mounting at the upper and lower both ends in window opening, and the length of mount 1 is unanimous with the length of the upper and lower end in window opening, is equipped with fixed slide rail 11 along length direction respectively on two mounts 1 in order to be used for installing window body 2, and fixed slide rail 11 can be the closed groove structure in track bottom, also can be the unclosed through-hole structure in track bottom, for the installation of the follow-up other structures of cooperation, this embodiment adopts the through-hole structure. Fulcrum shafts 21 are respectively arranged at the upper end and the lower end of the window body 2, the fulcrum shafts 21 are cylindrical, the axial direction is vertical to the fixed frames 1, and when the window body 2 is installed, the fulcrum shafts 21 at the two ends of the window body 2 are respectively inserted into the fixed slide rails 11 of the two fixed frames 1. In order to prevent the window body 2 from falling off from the two fixing frames 1, one end of the fulcrum shaft 21 is connected with the window body 2, and the other end of the fulcrum shaft passes through the fixed sliding rail 11 of the through hole structure and is provided with a stop block, and the length and the width of the stop block are both larger than the width of the fixed sliding rail 11. At this time, considering the thickness of the stop block, it is not suitable to be mounted between the fixing frame 1 and the end of the window opening tightly, and a gap should be left, so a suspension rod is usually arranged on the fixing frame 1, and the suspension rod is connected with the end of the window opening through an expansion screw.

Since the shaft 21 is cylindrical, in practice, after the shaft 21 is inserted into the fixed slide rail 11, the shaft 21 can directly rotate around its central axis in the fixed slide rail 11, and can also slide along the fixed slide rail 11, so that the shaft 21 can be rotatably and slidably disposed in the fixed slide rail 11. However, in order to improve the smoothness of the rotation and sliding, a slider may be provided in the fixed rail 11, a through hole may be provided in the center of the slider, and the support shaft 21 may be rotatably connected to the through hole via a rotary bearing. Under the action of the slide block, the fulcrum shaft 21 can slide smoothly, so that the window body 2 is driven to slide; the fulcrum shaft 21 can smoothly rotate under the action of the rotation bearing, thereby driving the window 2 to rotate. Alternatively, the pivot shaft 21 may be designed as a slider, and the pivot shaft 21 and the window 2 may be connected by a pivot bearing. The foregoing design is adopted in this embodiment. Based on this, when the window body 2 is rotated to the plane where the window body is located and the plane where the two fixing frames 1 are located coincide, the closing state of the window body 2 is obtained; when the window body 2 is rotated to a plane where the window body is located and the plane where the two fixing frames 1 are located form a certain included angle, the window body 2 is in an opening state, and the opening area is different according to the difference of the included angle. After the window bodies 2 are rotated to the plane where the window bodies are perpendicular to the plane where the two fixing frames 1 are located, all the window bodies 2 are overlapped in a sliding mode, and therefore the folding of the window bodies 2 is achieved.

It can be seen that window 2 rotates around the axis of fulcrum shaft 21, and in the prior art, fulcrum shaft 21 is usually disposed above and below one side end of window 2, and in this structure, when window 2 rotates around fulcrum shaft 21, the occupied area is large because window 2 is drawn by taking the whole width of window 2 as a radius. And it also hinges the other side end of window 2 to the side end of the adjacent window in order to maintain the balance of the rotation of window 2, thereby causing the failure of opening between two windows 2. In this embodiment, fulcrum 21 sets up on the center pin extension of window form 2, and window form 2 uses half of its width to draw a circle as the radius when rotating, has reduced the position that occupies when window form 2 rotates, has also guaranteed the equilibrium when window form 2 rotates, and consequently, two adjacent window forms 2 also need not articulate, when window form 2 rotates to the plane of place and two mount 1 place planes coincide, the side of two adjacent window forms 2 butt each other can, can open between two window forms 2, improve the flexibility of windowing.

Because of the large number of windows 2, it is necessary to push windows 2 one by one to slidably overlap during a folding operation. Thus, in the present application, a folding structure 3 is also included that controls the sliding of window 2.

As shown in fig. 2, the folding structure 3 comprises a folding strip 31, the folding strip 31 comprises a plurality of connecting rods 311 connected in sequence, the end of the front connecting rod 311 is rotatably connected with the end of the rear connecting rod 311, and when two adjacent connecting rods 311 are rotated to be parallel to each other around the rotating connection between them, the two connecting rods 311 are considered to be folded together. For example, as shown in fig. 3 and fig. 4, two ends of the connecting rod 311 of this embodiment are respectively provided with a collar 311a (only one end is shown in the figures), the collars 311a of two adjacent connecting rods 311 are sleeved on a shaft body 312, in order to ensure that the two connecting rods 311 can rotate relatively, at least one of the two collars 311a on the shaft body 312 is rotatably connected with the shaft body 312, and in this embodiment, both the two collars 311a are rotatably connected with the shaft body 312 through a rotating bearing. Since the following connection rod 311 needs to be connected to the window 2, it is preferable to make the two connection rods 311 flush for the purpose of leveling the window 2, and therefore the thickness of the collar 311a is preferably smaller than that of the connection rod 311, as shown in fig. 3, the collar 311a of the left connection rod 311 is disposed at the upper part of the end part thereof, the collar 311a of the right connection rod 311 is disposed at the lower part of the end part thereof, and when the collars 311a of the two connection rods 311 are sleeved on the shaft body 312, the two connection rods 311 are flush. Further, in order to protect the connection portion between the collar 311a and the shaft body 312, a sleeve 313 may be further sleeved outside the shaft body 312, and an arc-shaped strip hole is formed in a side surface of the sleeve 313; a limiting rod 311b is arranged between the connecting rod 311 and the lantern ring 311a, one end of the limiting rod 311b is positioned outside the sleeve 313 and connected with the connecting rod 311, and the other end of the limiting rod 311b penetrates through the arc-shaped strip hole to enter the sleeve 313 and is connected with the lantern ring 311 a. When the connecting rod 311 rotates, the limiting rod 311b also rotates in the arc-shaped bar hole, and the rotating angle of the connecting rod 311 can be controlled by controlling the length of the arc-shaped bar hole.

As shown in fig. 2, when the folding strip 31 is mounted on the window 2, the control link 311 is first perpendicular to the axial direction of the fulcrum shaft 21, and then the connecting links 311 are respectively connected with the fulcrum shafts 21 at the lower end of the window 2, which may be fixedly connected or rotatably connected, but considering that the fixed connection, the folding and rotating of the window 2 cannot be performed separately, the embodiment adopts a rotating connection manner. In order to ensure stability, a connecting sleeve is generally arranged at the center of the connecting rod 311, and the connecting sleeve is rotatably connected with the fulcrum shaft 21 through a rotating bearing, and at this time, the window body 2 can rotate freely and can be driven by the folding strip 31 to slide. Meanwhile, in order to enhance the strength of the folded piece 31, two identical folded pieces 31 may be stacked one on top of the other.

When folding, it is necessary to rotate the several windows 2 to a plane that forms a certain angle with the plane of the two fixing frames 1, so that the several windows 2 are overlapped together, preferably to a plane that is perpendicular to the plane of the two fixing frames 1. Then, the free end of the most lateral link 311 is pushed, for example, as shown in fig. 2, the right end of the most right link 311 is pushed to rotate counterclockwise, and the link 311 itself rotates counterclockwise around the fulcrum 21, so that the left end of the link 311 appears to move rightward and outward in position, and in cooperation therewith, the right end of the second link 311 connected thereto should also move rightward and outward. To achieve this result, the second connecting rod 311 moves rightward along the fixed rail 11 as a whole, and rotates clockwise about the fulcrum 21 to move the right end portion thereof rightward and forward. As the second connecting rod 311 moves, the window 2 connected thereto moves rightward closer to the rightmost window 2. And the movement and rotation of the second connecting rod 311 drives the next connecting rod 311 to move and rotate in the same manner, thereby realizing the movement of all windows 2. The distance between the two window bodies 2 is related to the included angle between the two connecting rods 311, when the rightmost connecting rod 311 rotates counterclockwise to be perpendicular to the fixed mount 1, the second connecting rod 311 is driven by the connecting rod to be perpendicular to the fixed mount 1, and the two connecting rods 311 are attached together, so that the two window bodies 2 are overlapped together, and the folding of the window bodies 2 is completed.

Since the one link 311 at the outermost side is also pivotally connected to the pivot shaft 21, and the pivot shaft 21 is pivotally connected to the slider in the fixed rail 11, when the link 311 is controlled to pivot, the pivot shaft 21 is easily pivoted and easily slides in the fixed rail 11, and a rotational force is not easily applied. Therefore, the folding structure 3 further comprises a folding control handle 32, as shown in fig. 2, a first fixed shaft 12 parallel to the fulcrum shaft 21 is provided on the fixed frame 1, a middle portion of the folding control handle 32 is rotatably connected with the first fixed shaft 12 through a rotating bearing, one end of the folding control handle 32 forms a folding connection end and is rotatably connected with an end portion of a most lateral connecting rod 311 of the folding strip 31, the specific structure of the rotating connection is identical with the rotating connection structure between the two connecting rods 311, and the other end of the folding control handle 32 forms a folding control end. Since the first stationary axle 12 is stationary, it is preferable to apply a force when controlling the folding control handle 32 to rotate about the first stationary axle 12. When the folding control end of the folding control handle 32 is controlled to rotate clockwise, the folding connecting end moves rightwards and inwards, so that the connecting rod 311 at the most lateral side is driven to move rightwards and rotate anticlockwise, and then the folding operation is finished in a consistent manner. Meanwhile, in order to save labor, the folding control handle 32 includes a connection portion rotatably connected to the first fixing shaft 12, a resistance portion between the connection portion and the folding connection end, and a power portion between the connection portion and the folding control end, and the length of the power portion is set to be greater than that of the resistance portion according to a lever principle.

Because before folding, need all rotate a plurality of windows 2 earlier and be certain contained angle to the plane of place and two mount 1 place planes, preferred a plurality of windows 2 are parallel to each other for this application has still set up the integrative pivoted angle modulation structure 4 of a plurality of windows 2 of control.

As shown in fig. 5, the angle adjusting structure 4 includes an adjusting bracket 41. The adjusting rack 41 is provided with an adjusting slide rail 411 parallel to the fixed slide rail 11, a plurality of connecting shafts 412 parallel to the fulcrum shafts 21 are arranged in the adjusting slide rail 411, the connecting shafts 412 are rotatably and slidably arranged in the adjusting slide rail 411, similar to the fulcrum shafts 21, the cylindrical connecting shafts 412 can basically directly realize the rotation and the sliding, but in order to improve the fluency, a slide block is also arranged in the adjusting slide rail 411, and the connecting shafts 412 are connected with through holes on the slide block through rotating bearings. The number of the connecting shafts 412 is the same as that of the windows 2, and the connecting shafts 412 are connected with the fulcrum shafts 21 at the lower ends of the windows 2 through the connecting swing arms 211, and since the fulcrum shafts 21 and the connecting shafts 412 are rotatable, the connecting swing arms 211 are fixedly connected with the fulcrum shafts 21 and the connecting shafts 412. In this embodiment, since the stopper is provided just above the fulcrum shaft 21, a part of the stopper is directly used as the connecting swing arm 211: the lower end of the fulcrum shaft 21 passes through the fixed slide rail 11 and then is connected with the center point of the stop block, the end of the stop block is connected with the upper end of the connecting shaft 412, and the part of the stop block between the end and the center point is the connecting swing arm 211.

Since the length of the connecting swing arm 211 is fixed, if the adjusting bracket 41 is moved to change the distance between the fixed slide rail 11 and the adjusting slide rail 411 in the horizontal direction, the fulcrum shaft 21 or the connecting shaft 412 must be rotated to fit the connecting swing arm 211 to the distance. For example, at the beginning, the horizontal distance between the fixed slide rail 11 and the adjusting slide rail 411 is exactly the same as the length of the connecting swing arm 211, and at this time, the connecting swing arm 211 is perpendicular to the fixed slide rail 11; the adjusting slide rail 411 is moved to reduce the horizontal distance between the fixed slide rail 11 and the adjusting slide rail 411, at this time, an included angle is formed between the connecting swing arm 211 and the fixed slide rail 11, the connecting swing arm 211 is fixedly connected with the fulcrum shaft 21, and the rotation of the connecting swing arm 211 inevitably drives the fulcrum shaft 21 to rotate. This is utilized in the present embodiment to regulate the rotation of the fulcrum shaft 21 and thus the rotation of the window 2. In addition, considering that when the window 2 rotates to the plane coincident with the plane of the two fixed frames 1, the horizontal distance between the fixed slide rail 11 and the adjusting slide rail 411 is zero, and the two are located on the same vertical plane, therefore when installing, it is necessary to make the adjusting frame 41 not be on the same horizontal plane with the fixed frame 1, and the adjusting frame 41 is generally disposed below the fixed frame 1 located below.

In order to facilitate the control of the movement of the adjusting frame 41, the angle adjusting structure 4 of the present embodiment further includes an angle control handle 42, the fixing frame 1 is provided with a second fixing shaft 13 parallel to the fulcrum shaft 21, a middle portion of the angle control handle 42 is provided with a connecting sleeve to be rotatably connected with the second fixing shaft 13 through a rotating bearing, one end of the angle control handle 42 forms an adjusting connecting end and is rotatably connected with the adjusting frame 41, and the other end forms an angle control end. The angle control handle 42 also includes a connection portion rotatably connected to the second fixing shaft 13, a power portion between the connection portion and the angle control end, and a resistance portion between the connection portion and the adjustment connection end, and the length of the power portion is set to be greater than that of the resistance portion for saving labor. Meanwhile, an included angle of 75-105 degrees, preferably 90 degrees, is formed between the power part and the resistance part. In addition, in order to ensure the stability of the adjusting bracket 41, as shown in fig. 6, the second fixing shafts 13 are usually disposed at two ends of the fixing bracket 1, one end of the adjusting bracket 41 is connected to one second fixing shaft 13 through the angle control handle 42, the other end is connected to the other second fixing shaft 13 through a connecting arm, one end of the connecting arm is rotatably connected to the adjusting bracket 41, and the other end is rotatably connected to the second fixing shaft 13.

When the window is used, as shown in the top view of fig. 7, the angle control handle 42 rotates counterclockwise by a certain angle, under the driving of the angle control handle, the adjusting frame 41 moves upward and rightward according to the direction in fig. 7, the distance between the adjusting slide rail 411 and the fixed slide rail 11 decreases, the fulcrum shaft 21 is limited by the folding structure and cannot slide, so the connecting shaft 412 slides leftward, the connecting swing arm 211 is driven to rotate clockwise, the fulcrum shaft 21 is driven to rotate clockwise, and the window 2 is driven to rotate clockwise to adjust the angle.

Based on the structure, the installation method of the assembled folding window with the adjustable corner comprises the following steps:

s1, cutting the two fixing frames 1 to the length consistent with the length of the upper end and the lower end of the window opening, then fixedly connecting the two fixing frames 1 with the upper end and the lower end of the window opening respectively through screws, simultaneously controlling a gap for inserting a stop block to be reserved between the fixing frame 1 and the upper end of the window opening, and controlling a gap for installing the stop block and the angle adjusting structure 4 to be reserved between the fixing frame 1 and the lower end of the window opening.
