Description

Technical Field

[0001] This invention relates to the field of door and window hardware, and in particular to a double outward-opening hardware system and window structure. Background Technology Integrated window screens offer several advantages in home applications, such as balancing insect protection and ventilation, enhancing security, providing privacy, and maintaining a clear view. Traditional integrated window screens, if designed as double-pane outward-opening windows, will have the screen panel directly obstructing the glass panel handle, rendering the glass panel completely unusable independently. To solve this problem, the industry has compromised by using either a "at least one inward-opening panel" (e.g., inward-opening screen panel + outward-opening glass panel) or a "double-pane fully inward-opening" solution. However, inward-opening panels inevitably occupy valuable indoor space, affecting furniture placement, daily passage, and reducing space utilization in small apartments and narrow corridors.

[0002] Therefore, a new technical solution needs to be researched to address the above problems. Summary of the Invention

[0003] To address the shortcomings and deficiencies of the existing technology, this invention provides a double outward-opening hardware system and window structure. By designing a double outward-opening hardware system, the first and second handles can be selectively linked, allowing the glass window to be operated from inside the room through a screen. This eliminates the problem of having to use an "inward-opening screen" in the existing technology. Furthermore, the absence of an inward-opening fan body occupies indoor space, solving problems such as furniture placement and passage obstruction caused by traditional "inward-opening screen + outward-opening glass window" or "double inward-opening windows".

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A double-outward-opening hardware system includes a first handle and a second handle. The first handle includes a first base, a first handle, and a locking component. The first handle and the locking component are linked together and can both rotate up and down around the first base. The locking component is provided with a first control part and a second control part. The second handle includes a second base and a second handle. The second handle can rotate up and down around the second base. The second handle can selectively engage with the engaging component. When the second handle and the engaging component are engaged, the first control unit can selectively control the second handle to rotate up or down, and the second control unit can selectively control the second handle to move outward or inward.

[0005] As a preferred embodiment, the engaging component is provided with an engaging cavity that extends in a left-right direction, and the second handle is adapted to the engaging cavity; the engaging component engages with the second handle through the engaging cavity.

[0006] As a preferred embodiment, the engaging cavity is arranged through the left and right directions; the length of the second handle in the left and right directions is greater than the length of the engaging cavity in the left and right directions.

[0007] As a preferred embodiment, the first control unit includes a first hook disposed above the engagement cavity, and the left side of the first hook is provided with an avoidance cutout; the second control unit includes a second hook disposed outside the engagement cavity.

[0008] As a preferred embodiment, the second hook is movable; the second hook is connected to an unlock button.

[0009] A window structure includes a window frame, a screen sash, a glass sash, and the aforementioned double outward-opening hardware system; the screen sash and the glass sash are both installed on the window frame, and the screen sash is located inside the glass sash; the screen sash is equipped with a first handle, and the glass sash is equipped with a second handle.

[0010] As a preferred embodiment, the window sash is connected to the window frame via the hinge assembly and the screen sash is connected to the window frame via the hinge assembly.

[0011] Compared with existing technologies, this invention has significant advantages and beneficial effects. Specifically, as the above technical solution shows, it mainly solves the technical problem of "the screen fan obstructing the glass fan handle and making it impossible to operate" in traditional integrated double-opening window screens. Through the mechanical design of linking the screen fan handle with the glass fan, the glass fan does not require a separate handle, enabling both the screen fan and the glass fan to open outwards simultaneously, eliminating the need for "inward opening of the screen fan" in existing technologies. Furthermore, both fans adopt an outward opening mode, eliminating the need for inward-opening fans that occupy indoor space, solving the problems of furniture placement and passage obstruction caused by traditional "inward opening of the screen fan + outward opening of the glass fan" or "double inward opening of the fans," making it particularly suitable for compact spaces such as small apartments and narrow corridors. Moreover, a single set of linkage hardware integrates the control function of both fans, reducing the number of parts and lowering costs compared to traditional two sets of independent hardware, making it more conducive to market promotion.

[0015] The technical solutions of this embodiment of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are merely preferred embodiments of the present invention.

[0016] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly attached to the other element or there may be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0017] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0018] See attached document Figures 1 to 12 A double-outward-opening hardware system and window structure in an embodiment of the present invention includes a first handle 10 and a second handle 20. The first handle 10 includes a first base 11, a first handle 12, and a locking component 13. The first handle 12 and the locking component 13 are linked together and can both rotate up and down around the first base 11. The locking component 13 is provided with a first control part 132 and a second control part 133. The second handle 20 includes a second base 21 and a second handle 22. The second handle 22 can rotate up and down around the second base 21. The second handle 22 can selectively cooperate with the locking component 13. When the second handle 22 and the locking component 13 are in cooperation: the first control part 132 can selectively control the second handle 22 to rotate up or down, and the second control part 133 can selectively control the second handle 22 to move outward or inward.

[0019] In a preferred embodiment, the engaging component 13 is provided with an engaging cavity 131, which extends in the left-right direction. One end of the engaging cavity 131 is provided with an opening for the second handle 22 to enter and exit. The second handle 22 is adapted to the engaging cavity 131. The engaging component 13 cooperates with the second handle 22 through the engaging cavity 131.

[0020] After installation, depending on the usage state, the second handle 22 can selectively extend into the engaging cavity 131. When the second handle 22 is located in the engaging cavity 131, the engaging component 13 can selectively push the second handle 22 upward or downward through the first control unit 132, and the engaging component 13 can selectively push the second handle 22 outward or inward through the second control unit 133 (in practical applications, this can also be understood as unfolding or retracting the glass fan described below). The synchronous linkage structure of the first handle 12 and the engaging component 13 can adopt a common connection structure, such as mounting the first handle 12 and the engaging component 13 on the same rotating shaft (square shaft).

[0021] Furthermore, the engaging cavity 131 is arranged through the left and right direction; as a preferred embodiment, the length of the second handle 22 in the left and right direction is greater than the length of the engaging cavity 131 in the left and right direction. This shortens the length of the engaging component 13 and increases user convenience. It should be noted that in actual applications, the length of the second handle 22 in the left and right direction can also be equal to or less than the length of the engaging cavity 131 in the left and right direction. The fact that the length of the second handle 22 in the left and right direction is greater than the length of the engaging cavity 131 in the left and right direction in this embodiment is merely an example of a preferred embodiment.

[0022] Furthermore, the first control unit 132 includes a first hook 1321 disposed above the engaging cavity 131 and a first blocking surface 1322 disposed below the engaging cavity 131. The first handle 10 pushes the second handle 22 to rotate upward or downward through the first hook 1321 and the first blocking surface 1322 of the engaging component 13. Preferably, the left side of the first hook 1321 is provided with an avoidance cutout (semi-enclosed setting). In this way, it is easier to disengage the second handle 22 from the engaging component 13, and the travel distance required for the glass fan 300 to disengage when the first handle 10 and the second handle 20 are disconnected.

[0023] Further, the second control unit 133 includes a second hook 1331 disposed on the outside of the engaging cavity 131 and a second blocking surface 1332 disposed on the inside of the engaging cavity 131. The engaging component 13 pushes the second handle 22 (hereinafter referred to as the glass fan 300) to open outward or close inward through the second blocking surface 1332 and the second hook 1331. The first blocking surface 1322, the second blocking surface 1332, the first hook 1321, and the second hook 1331 together form the engaging cavity 131. Preferably, the second hook 1331 is movably disposed, and the second hook 1331 is connected to an unlocking button 23. One implementation is briefly described here: see [link to implementation details]. Figure 10 An elastic element, such as a spring, is built into the first handle 10, allowing the second hook 1331 to be elastically and movably installed on the locking component 13. An unlocking button 23 is provided on the first handle 12 and is connected to the second hook 1331. When the window needs to be closed in conjunction with the handle: the screen sash 200 opens outwards and abuts against the glass sash 300, and the second hook 1331 is automatically engaged into the locking cavity 131 by the elastic element; pulling the first handle 12 will close the glass sash 300.

[0024] When the first handle 10 and the second handle 20 need to be disengaged, after opening the glass fan 300 to the corresponding position, press the unlock button 23. The unlock button 23 drives the second hook 1331 to compress the elastic element, and by pulling the first handle 12, the second hook 1331 is disengaged from the glass fan 300. In this way, the screen fan 200 can be closed independently, while the glass fan 300 remains open.

[0025] This embodiment also discloses a window structure (including but not limited to an integrated window screen window), which includes a window frame 100, a screen sash 200, a glass sash 300, and the aforementioned double outward-opening hardware system; the screen sash 200 and the glass sash 300 are both installed on the window frame 100; the screen sash 200 is equipped with the aforementioned first handle 10, and the glass sash 300 is equipped with the aforementioned second handle 20; both the first handle 10 and the second handle 20 have locking points for locking with the lock seat of the window frame 100. The driving connection between the first handle 12 / second handle 22 and the locking points can be driven by a structure such as gear meshing, which is conventional technology and will not be described in detail here.

[0026] The following further explains the window opening process of this window structure: (e.g.) Figure 1 As shown: Both the screen sash 200 and the glass sash 300 are closed and locked to the window frame 100: the first handle 12, the second handle 22, and the locking component 13 are all in the up-down direction; both the screen sash 200 and the glass sash 300 are in contact with the window frame 100; the locking points of the screen sash 200 and the glass sash 300 are locked to the corresponding locking seats on the window frame 100; and the second handle 22 is completely located in the locking cavity 131. By rotating Figure 1 The first handle in the middle is at the 12-degree unlocking angle (e.g.) Figure 2 As shown), at this time: because the first handle 10 is linked to the second handle 20 (the first handle 12 is still fully engaged with the second handle 22 through the locking component 13 and is in a linked state), the second handle 22 also rotates relatively; the locking points of the first handle 10 on the screen sash 200 and the second handle 20 on the glass sash 300 are separated from the corresponding lock seats on the window frame 100 and enter the unlocked state.

[0027] Next, the first handle 12 (linked to the glass fan 300) is pushed outward to a specific position, at which point the second handle 22 (the end section) is located in the engaging cavity 131 (as shown). Figure 3 (As shown); at this time, the first handle 12 can still control the second handle 22 (glass fan 300) to open outward or retract inward.

[0028] Then, by turning the first handle 12 downwards, the second handle 22 is completely disengaged from the first handle 12 (as shown). Figure 4As shown), the glass sash 300 and the screen sash 200 are in a decoupled state; the screen sash 200 can be pulled back to the locked position of the window frame 100 at this time; the glass sash 300 remains in the open position.

[0029] Furthermore, when the user needs to close the window: the screen sash 200 needs to be reopened and pressed against the glass sash 300. By operating the first handle 12 and rotating it to a certain angle, the locking component 13 and the second handle 22 are re-engaged, establishing a linkage state. Then, by pulling the first handle 12, the second handle 22 (glass sash 300) is moved inwards synchronously until both the screen sash 200 and the glass sash 300 are in contact with the window frame 100. At this time, the locking component 13 and the second handle 22 are fully engaged. Finally, by operating the first handle 12 and rotating it to the locking angle, the locking points of the screen sash 200 and the glass sash 300 and the lock seat on the window frame 100 are re-locked (returning to the previous state). Figure 1 state).

[0030] See in different application scenarios Figure 1 and Figure 2 The first handle 10 can be installed on the side adjacent to the screen 50, and the second handle 20 can be installed on the side adjacent to the glass. (See also...) Figure 11 and Figure 12 The first handle 10 can also be installed on the side closer to the interior (front), and the second handle 20 can also be installed on the side closer to the interior (front). No specific limitations are made here.

[0031] Furthermore, it also includes a hinge assembly 30 and a hinge assembly 40. The hinge assembly 30 is used to connect the glass sash 300 and the window frame 100, and the hinge assembly 40 is used to connect the screen sash 200 and the window frame 100. When opened, since the rotation center axes of the glass sash 300 and the screen sash 200 are different, a positional difference will be generated between the glass sash 300 and the screen sash 200 when opened, thereby satisfying the disengagement conditions of the first handle 10 and the second handle 20.

[0032] The key design feature of this invention is to solve the technical problem of "the screen fan obstructing the glass fan handle and making it impossible to operate" in traditional double-opening window screen systems. Through a mechanical design that links the screen fan handle to the glass fan, the glass fan does not require a separate handle, allowing both the screen and glass fans to open outwards simultaneously, eliminating the need for an "inward-opening screen fan" in existing technologies. Furthermore, both fans operate in an outward-opening mode, eliminating the need for inward-opening fans that occupy indoor space. This solves the problems of furniture placement and passage obstruction caused by traditional "inward-opening screen fan + outward-opening glass fan" or "double-inward-opening fans," making it particularly suitable for small apartments, narrow hallways, and other compact spaces. Moreover, a single set of integrated hardware controls both fans, reducing the number of components compared to traditional two separate sets of hardware, resulting in lower costs and greater market appeal.

[0033] The above description is merely a preferred embodiment of the present invention and does not constitute any limitation on the technical scope of the present invention. Therefore, any minor modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present invention shall still fall within the scope of the technical solution of the present invention.
