The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0060] Example 1

[0061] See also Figure 1-Figure 13 The present embodiment discloses a flat opening flip hinge, which can be applied as an inward opening and inverting hinge, so that the window sash can be opened inwardly and hung inwardly. The hinge comprises a frame mounting member 1, a sash connecting member 2, a hinge rod member group 3, a first flip member 6, a second flip member 9 and a connecting piece 5; the frame mounting member 1 is arranged on the window frame profile, and the sash connecting member 2 is connected to the sash frame. At the same time, in order to improve the flexible adjustment function of the hinge, the flat opening flip hinge of the present embodiment is also provided with a left and right adjustment component and a sealing adjustment component.

[0062] The frame mounting member 1 of this embodiment includes a horizontal frame mounting plate 101 and a vertical frame mounting plate 102. The horizontal frame mounting plate 101 is arranged on the horizontal frame of the window frame profile; the vertical frame mounting plate 102 includes a fixing portion 1021 and an assembly portion 1022; the fixing portion 1021 and the assembly portion 1022 are perpendicular to each other, the fixing portion 1021 is connected to the vertical frame of the window frame profile, and the assembly portion 1022 is located below one end of the horizontal frame mounting plate 101. The frame mounting member 1 of this embodiment includes a horizontal frame mounting plate 101 and a vertical frame mounting plate 102, which can be connected to both the horizontal frame and the vertical frame of the window frame, which is conducive to improving the connection stability between the frame mounting member 1 and the window frame, and is convenient for setting the sealing adjustment component, and improving the stability of the adjustment amount after the sealing adjustment.

[0064] The hinge rod of this embodiment includes a first connecting rod 301, a second connecting rod 302 and a third connecting rod 303, and the middle sections of the first connecting rod 301 and the second connecting rod 302 are hinged to each other. A first connecting hole 3011 is provided at the first end of the first connecting rod 301, and a connecting sheet 5 is provided on the surface of the transverse frame mounting plate 101 away from the window frame profile, i.e., the upper surface. The first flip member 6 passes through the first connecting hole 3011 and is fastened to the connecting sheet 5; at the same time, the first connecting hole 3011 is loosely matched with the first flip member 6, and a first avoidance portion 6011 is provided on the first flip member 6, so that the first connecting rod 301 can rotate or flip relative to the first flip member 6. When flipping, the first connecting rod 301 performs a flipping motion relative to the first flip member 6. In this embodiment, the first connecting hole 3011 and the first flip member 6 are fitted with clearance, so that the first end of the first connecting rod 301 can rotate relative to the first flip member 6, and flip at a small angle in the Y-axis and Z-axis directions. The small angle flip can be understood as greater than 1° and less than 30°. Of course, the small angle flip can be flexibly adjusted and changed, and the utility model is not limited to this. The second end of the first connecting rod 301 is connected to the horizontal opening rotation axis 10 of the fan connecting member 2. In addition, the connecting piece 5 is arranged on the upper surface of the horizontal frame mounting plate 101, and is used to fasten the first flip member 6 to fix the first flip member 6. The structure is simple, easy to install and maintain, and can simplify the structure of the horizontal frame mounting plate 101.

[0065] The transverse frame mounting plate 101 is provided with a first slide groove 1013, and the first slide groove 1013 extends along the X-axis direction; the second flipping member 9 is clearance-matched with the first slide groove 1013 and can slide in the first slide groove 1013, and the second flipping member 9 is provided with a second avoidance portion 902; the first end of the second connecting rod 302 is connected to the second flipping member 9 through the first connecting member 12; when flipping, the second connecting rod 302, the first connecting member 12 and the second flipping member 9 flip together relative to the frame mounting member 1 in the Y-axis and Z-axis directions.

[0066] The second end of the second connecting rod 302 is hinged to the first end of the third connecting rod 303, and the second end of the third connecting rod 303 is hinged to the middle section of the sash connector 2. The hinge rod assembly 3 of this embodiment can refer to the casement window hinge in the prior art.

[0067] Furthermore, the first connecting hole 3011 of the present embodiment adopts a countersunk hole, including a first hole segment 30111 and a second hole segment 30112. The diameter of the first hole segment 30111 is larger than the diameter of the second hole segment 30112, and the second hole segment 30112 passes through the first connecting rod 301. The first flip member 6 can adopt a pin structure or a part with a certain axial length similar to a pin structure. The first flip member 6 of the present embodiment is provided with a first rotating part 601 and a second rotating part 602. The first rotating part 601 cooperates with the first hole segment 30111, and the second rotating part 602 cooperates with the second hole segment 30112; the first avoidance part 6011 is arranged at the first rotating part 601. In order to better allow the first end of the first connecting rod 301 to flip relative to the first flip member 6, the first avoidance part 6011 of the present embodiment is a partial cut angle of the bottom surface of the first rotating part 601, for details, please refer to Figure 5 and Fig.13 .

[0068] The hinge of this embodiment also has a left-right adjustment function. In order to better combine the left-right adjustment function with the flipping function of the window sash, this embodiment uses the connecting piece 5 as a part of the left-right adjustment component, and the left-right adjustment component also includes a first adjustment member 4. Specifically, the horizontal frame mounting plate 101 is provided with a second connection hole 1015, and the connecting piece 5 is provided with a first guide hole 501. The first adjustment member 4 is inserted into the first guide hole 501 and the second connection hole 1015, and the first adjustment member 4 is eccentrically matched with the first guide hole 501. The first adjustment member 4 can be connected to the second connection hole 1015 by riveting, and the first adjustment member 4 has a rotatable function. Preferably, the first guide hole 501 of this embodiment is set as a round hole, so that the first adjustment member 4 can better cooperate with it, and drive the connecting piece 5 to swing and move along the X-axis, so as to achieve left-right adjustment of the hinge rod group.

[0069] Furthermore, a first guide hole 1014 is provided on the transverse frame mounting plate 101, and the first guide hole 1014 extends along the X-axis direction. A first through hole 502 is provided on the connecting plate 5; the first flip member 6 is sequentially inserted into the first connecting hole 3011, the first through hole 502 and the first guide hole 1014, and the first flip member 6 can slide in the first guide hole 1014 driven by the connecting plate 5.

[0070] Compared with the prior art, the connecting piece 5 of this embodiment is located on the upper surface of the transverse frame mounting plate 101, and there is no need to set a guide structure or other limiting structure at the connection between the transverse frame mounting plate 101 and the connecting piece 5, that is, the corresponding part of the transverse frame mounting plate 101 and the connecting piece 5 can be smoothly arranged, and the effect of simplifying the structure is particularly obvious. Under this condition, when adjusting left and right, driven by the first adjusting member 4, the connecting piece 5 will swing due to the eccentric fit with it, and at the same time, combined with the guiding effect of the first flip member 6 and the first guide hole 1014, it will move left and right, that is, move along the X-axis, and drive the hinge rod group 3 to move, so as to achieve the left and right adjustment effect.

[0071] In addition, in this embodiment, the first through hole 502 is set as a special-shaped hole. The first flip member 6 is provided with a connecting portion 603 matching the first through hole 502. Specifically, the first through hole 502 of this embodiment is provided with a missing corner on the basis of a round hole, so that when it cooperates with the connecting portion 603 of the first flip member 6, it can effectively limit the rotation of the first flip member 6. Of course, the first through hole 502 can also be set as a hole of other shapes, such as a hexagonal hole, and correspondingly, the connecting portion 603 of the first through hole 502 can be matched and set to a corresponding shape. This practice can further improve the fastening effect between the first flip member 6 and the connecting piece 5. This embodiment is fastened and connected with the first flip member 6 through the first through hole 502, which can be more conveniently adapted to the left and right adjustment components, and utilizes the original structure on the connecting piece 5. The design is ingenious, forming a hinge that can be opened and flipped horizontally and adjusted left and right, and the structure of the left and right adjustment components is simple.

[0072] As another embodiment, when the hinge does not need the left-right adjustment function, the first flip member 6 of this embodiment can be set to be fastened to the horizontal frame mounting plate 101, and such a connection method can also achieve the fixation of the first flip member 6 and the effect of the first connecting rod 301 performing a flipping movement relative to the first flip member 6. Such a structure does not require additional assembly parts, and the structure is also simple and reliable.

[0073] The first flip member 6 is provided with a hook portion 605; the hook portion 605 is larger than the first guide hole 1014. The hook portion 605 can prevent the first flip member 6 from slipping out of the first guide hole 1014, and can be used to enhance the bearing capacity of the hinge rod assembly 3, especially when the window sash is flipped, which can significantly improve the bearing capacity and safety. The hook portion 605 of this embodiment can be formed by riveting. A retaining ring 14 is also provided between the hook portion 605 and the frame mounting member 1 in this embodiment.

[0074] Furthermore, in the Z-axis direction, the first flip member 6 of this embodiment is composed of a first rotating portion 601, a second rotating portion 602, a connecting portion 603, a guide portion 604, and a hook portion 605 from top to bottom. The guide portion 604 can directly adopt a cylindrical structure to facilitate cooperation with the first guide hole 1014, so that the first flip member 6 can be easily moved in the X-axis direction when adjusting left and right, thereby driving the left and right adjustment of the hinge rod assembly 3.

[0075] When the hinge rod assembly 3 needs to be adjusted in the left-right direction (i.e., the X-axis direction in the figure), the first adjusting member 4 is rotated, and the eccentric cooperation between the first adjusting member 4 and the first guide hole 501 on the connecting plate 5 is used to pull the connecting plate 5 to swing and move left-right, thereby driving the first flip member 6 and the hinge rod assembly 3 to move left-right as a whole. At the same time, by setting the first guide hole 1014, the moving direction of the first flip member 6 can be limited, further improving the accuracy and reliability of left-right adjustment, avoiding the hinge rod assembly 3 from being offset in other directions when performing left-right adjustment, especially avoiding the offset in the Y-axis direction of the horizontal frame mounting plate 101. In addition, the connecting plate 5 of this embodiment adopts a flat plate shape and can be formed by stamping, which has the advantage of low cost; at the same time, in this embodiment, no oblong hole structure is set on the connecting plate 5, and the first guide hole 501 and the first through hole 502 are both round hole structures, which is conducive to reducing the overall shaking of the product, and is also convenient for cooperation with the first flip member 6 and the first connecting rod 301, forming a hinge with left-right adjustment function and capable of flipping. In addition, since the first guide hole 501 on the connecting piece 5 of this embodiment adopts a round hole structure, it can be completely covered by the head of the first adjusting member 4 to prevent dust and debris from entering, thereby improving reliability and surface appearance.

[0076] In this embodiment, the second flip member 9 is provided with a raised stopper 901 on one side of the two sides in the length direction of the horizontal frame mounting plate 101, and an inwardly inclined inclined surface is provided on the other side, the inclined surface constitutes the second avoidance portion 902, and the upper part of the second avoidance portion 902 is vertically arranged. Fig.10 and Fig.11As shown, in the non-flipping state, the vertical surface above the second avoidance portion 902 cooperates with the first slide groove 1013 on the horizontal frame mounting plate 101, so that the first end of the second connecting rod 302 can slide along the second slide groove, thereby realizing the expansion or contraction of the hinge rod group 3, and completing the horizontal opening or closing of the window sash. When it is necessary to control the window sash to flip and form a downward hanging open state, there is a certain gap between the second avoidance portion 902 formed by the inclined surface and the first slide groove 1013, and the second flip member 9 is flipped to a certain angle in the Y-axis direction and the Z-axis direction; at the same time, since a limiting portion 901 is provided on the other side, the limiting portion 901 can abut against the window frame profile to improve the reliability after flipping and limit the flipping angle. In addition, the first connecting member 12 of this embodiment is fastened to the second flip member 9 by riveting, and the first end of the second connecting rod 302 is provided with a through hole to be rotatably connected to the first connecting member 12. A gasket 13 is further provided between the first end of the second connecting rod 302 and the cross frame mounting plate 101 to improve the smoothness of the operation of the hinge rod assembly 3 and reduce resistance during flipping.

[0077] The sealing adjustment assembly of this embodiment includes a second adjustment member 8. Among them, one end of the transverse frame mounting plate 101 located at the assembly portion 1022 is the adjustment end, the transverse frame mounting plate 101 is provided with a second guide hole 1016 at the adjustment end, and the assembly portion 1022 of the vertical frame mounting plate 102 is provided with a third connection hole 10221. The second adjustment member 8 is inserted into the second guide hole 1016 and the third connection hole 10221 and can rotate, and the second adjustment member 8 is eccentrically matched with the second guide hole 1016. The locking end of the transverse frame mounting plate 101 is locked on the transverse frame of the window frame profile by a locking structure, and the axis of the locking structure is a swing axis 11, and the swing axis 11 is parallel to the horizontal opening rotation axis 10 of the window sash; in the locked state of the locking structure, rotating the second adjustment member 8 can cause the transverse frame mounting plate 101 to swing around the swing axis 11.

[0078] In this embodiment, the second adjusting member 8 is arranged at the adjustment end of the horizontal frame mounting plate 101 and is separated from the hinge rod group 3. The second adjusting member 8 is not affected by the operation of the hinge rod group 3, which can effectively improve the stability of the window sash sealing adjustment amount, so that the second adjusting member 8 is not easy to loosen or wear. In addition, the other end of the horizontal frame mounting plate 101 is a locking end, that is, when adjusting, the swing amount of the horizontal frame mounting plate 101 and the hinge rod group 3 can be adjusted by adjusting the second adjusting member 8 alone, and the operation is simple and convenient. At the same time, the second adjusting member 8 and the horizontal frame mounting plate 101 are matched in an eccentric manner, which has a simple structure and a smooth and convenient feel when controlling.

[0079] The side of the second adjustment member 8 facing the outside world (the upper surface in this embodiment) is an operating surface, and a countersunk hole is provided on the operating surface, for example, it can be set as a hexagonal hole, and the adjustment member can be rotated by a hexagonal screwdriver to achieve the swing adjustment of the cross frame mounting plate 101. Preferably, in this embodiment, the second guide hole 1016 is set to an oblong shape, extending along the X-axis direction. Specifically, the second adjustment member 8 of this embodiment can be divided into an adjustment section, an eccentric section, a connecting section and a riveted section from top to bottom. The eccentric section is eccentrically matched with the second guide hole 1016, the connecting section is coaxially matched with the third connecting hole 10221, the riveted section is a portion formed after riveting with the third connecting hole 10221, and the adjustment section is located on the surface of the cross frame mounting plate 101. The eccentric section cooperates with the oblong second guide hole 1016 so that when the second adjusting member 8 rotates, the adjusting end of the horizontal frame mounting plate 101 is pushed to swing back and forth at a small angle around the swing axis 11. When the horizontal frame mounting plate 101 swings, the position of the hinge rod group 3 is also driven to swing synchronously, so that the position of the window sash can be adjusted to achieve the sealing adjustment of the window sash. The riveting between the second adjusting member 8 and the third connecting hole 10221 is a controlled torque riveting. After riveting, the second adjusting member 8 cannot move along the Z axis, but can be rotated after overcoming a certain torque, for example, it can be screwed with a tool; the advantage of this controlled torque riveting is to prevent the position of the second adjusting member 8 from being offset during operation.

[0080] In order to improve the accuracy of sealing adjustment, a swing guide structure is provided between the adjustment end of the transverse frame mounting plate 101 and the assembly portion 1022. The swing guide structure includes a guide column 1017 and a second guide hole 10222. The guide column 1017 is matched and inserted into the second guide hole 10222. The second guide hole 10222 matches the swing path of the adjustment end of the transverse frame mounting plate 101 or extends along the width direction of the transverse frame mounting plate 101. The guide column 1017 is provided on the transverse frame mounting plate 101, and the second guide hole 10222 is provided on the assembly portion 1022.

[0081] In order to make the horizontal frame mounting plate 101 more stable and accurate in swing adjustment and avoid deviation in other directions during the adjustment process, the present embodiment can effectively limit the swing direction of the adjustment end of the horizontal frame mounting plate 101 through the setting of the swing guide structure, and can especially limit the movement of the horizontal frame mounting plate 101 in the Y-axis direction. When adjusting the swing direction of the horizontal frame mounting plate 101, it is more of a small-angle swing, so the second guide hole 10222 can be set to an arc shape to match the swing path, and can also be set to extend along the Y-axis direction, and the small gap between the structural parts can also be used to achieve guidance and limit.

[0082] In addition, the guide column 1017 of this embodiment can also be arranged on the assembly portion 1022, and the second guide hole 10222 is arranged on the transverse frame mounting plate 101. In order to better maintain the appearance of the entire hinge, it is preferred to arrange the guide column 1017 on the transverse frame mounting plate 101, specifically, it can be arranged on the lower surface of the transverse frame mounting plate 101 and protrude downward, and the second guide hole 10222 is arranged on the assembly portion 1022, so that the number of slots on the surface of the transverse frame mounting plate 101 can be reduced.

[0083] The present embodiment adopts a locking structure to lock and fix the locking end of the transverse frame mounting plate 101, and the locking structure includes a clamping plate 15 and a clamping shaft 7; the clamping plate 15 is located below the locking end of the transverse frame mounting plate 101, and a groove 1011 is provided at the locking end of the transverse frame mounting plate 101, and a second through hole 1012 is provided on the groove 1011. After the clamping shaft 7 passes through the second through hole 1012, it is connected to the clamping plate 15 and can rotate synchronously.

[0084] Specifically, the head of the clamping shaft 7 can be accommodated by setting the groove 1011 to avoid protruding from the horizontal frame mounting plate 101. In addition, the clamping shaft 7 can cooperate with the clamping sheet 15 by setting a hexagonal hole on the clamping sheet 15, and setting the clamping shaft 7 and the hexagonal hole at the joint as a hexagonal prism structure, so that the synchronous rotation of the two can be achieved, and it is also convenient for the clamping shaft 7 to be inserted into the clamping sheet 15 and connected by riveting. The structure of the clamping sheet 15 of this embodiment can refer to the prior art, and can be locked and disassembled by rotating to achieve mutual contact or loosening with the slot on the horizontal frame.

[0085] As another embodiment, the locking structure may also be in other forms, for example, a screw may be used as a locking structure to lock the locking end of the transverse frame mounting plate 101, which can also achieve a locking and fixing effect. At this time, the axis of the screw is the swing axis 11. When adjusting the seal, it is necessary to loosen the screw appropriately first, for example, it can be in a semi-locked state, so that the transverse frame mounting plate 101 can swing. After completing the swing adjustment of the transverse frame mounting plate 101 to achieve the window sash seal adjustment, retighten the screw. Although the use of screws as a locking structure can also achieve the swing of the transverse frame mounting plate 101, the screws need to be adjusted and matched synchronously during operation, and the operation is not convenient enough. Therefore, it is preferred to use the locking method of the clamping sheet 15 and the clamping shaft 7.

[0086] The above description is only a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Therefore, any modification, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the technical solution of the present invention are still within the scope of the technical solution of the present invention.
