The use of "first" and "second" in the description is solely for the purpose of distinguishing technical features and is not to be construed as indicating or implying relative importance, implicitly specifying the number of the indicated technical features, or implicitly specifying the order of the indicated technical features.

[0027] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, and connecting should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0028] like Figures 1 to 3 As shown, a hand-operated casement window according to an embodiment of the first aspect of the present invention includes an outer frame 100, a sub-frame 200, an inner sash 300, and a glass sash 400. The outer frame 100 is disposed on the periphery of the sub-frame 200, the sub-frame 200 is disposed on the periphery of the inner sash 300, and the inner sash 300 is disposed on the periphery of the glass sash 400. The four components are sequentially surrounded to form the casement window. In this embodiment, the front side of the window is regarded as the outdoor space, i.e., the front direction; the rear side of the window is regarded as the indoor space, i.e., the rear direction; the height of the casement window is regarded as the vertical direction; and the width of the casement window is regarded as the left-right direction.

[0029] Specifically, the outer frame 100 is mounted on the window opening using fixing bolts, thereby forming a mounting base on the window opening. The outer frame 100 is composed of multiple aluminum profiles and is generally rectangular, but in other embodiments, it can also have other shapes such as circular or triangular. The outer frame 100 is used to securely connect to the sub-frame 200, providing a mounting base for the sub-frame 200.

[0030] For example, the sub-frame 200 is mounted on the inner edge of the outer frame 100. During production, the sub-frame 200 is typically assembled with the inner sash 300 and the glass sash 400 before being mounted on the inner edge of the outer frame 100. The sub-frame 200 is composed of multiple aluminum profiles, with its outer edge connected to the inner edge of the outer frame 100. The inner edge of the sub-frame 200 is provided with a second outer ring groove 210 and a second inner ring groove 220. Both the second outer ring groove 210 and the second inner ring groove 220 are arranged along the circumference of the inner edge of the sub-frame 200, and the second inner ring groove 220 is located behind the second outer ring groove 210, that is, the second inner ring groove 220 is closer to the interior space.

[0031] Since the sub-frame 200 needs to be installed horizontally when it is installed on the outer frame 100, the outer frame 100 cannot be provided with decorative strips that hinder the installation of the sub-frame 200. However, once the sub-frame 200 is installed, in order to stabilize the position of the sub-frame 200, the outer frame 100 is connected to a buckle cover 110 on the front side of the sub-frame 200. The buckle cover 110 is used to limit the sub-frame 200. The gap between the buckle cover 110 and the sub-frame 200 needs to be sealed with sealant to achieve waterproof and windproof effects.

[0032] For example, the inner sash 300 is composed of multiple aluminum profiles and has an inner edge and an outer edge. The inner edge is used to connect to the glass sash 400. After installation, the glass sash 400 needs to be fixed with sealant. The glass sash 400 should be positioned closer to the outdoor space to match the thermal insulation structure 330 of the inner sash 300 and improve thermal insulation performance. The glass sash 400 can optionally be double-layered soundproof glass to effectively improve thermal and sound insulation performance.

[0033] The outer edge of the inner door leaf 300 is provided with a first outer ring groove 310 and a first inner ring groove 320. Both the first outer ring groove 310 and the first inner ring groove 320 are arranged along the perimeter of the outer edge. The first inner ring groove 320 is located behind the first outer ring groove 310, that is, it is closer to the interior space. Furthermore, the position of the first inner ring groove 320 corresponds to that of the second inner ring groove 220, and together they form a rear notch. The position of the first outer ring groove 310 corresponds to that of the second outer ring groove 210, and together they form a front notch.

[0034] Both the rear slot and the front slot are used to install hardware, wherein the front slot is used to install the hinge 500. There are at least two hinges 500 and they are distributed in the up and down directions. The two ends of each hinge 500 are positioned and installed in the first outer ring groove 310 and the second outer ring groove 210 respectively. The front slot provides good positioning and fixation for the installation of the hinge 500, so that the inner fan 300 can be rotatably connected to the sub-frame 200 through the hinge 500.

[0035] Furthermore, a manual window opener 600 is connected to the bottom of the sub-frame 200. The manual window opener 600 has various structures, such as a structure in which an actuator 610 is extended and retracted by a manual crank, or a structure in which the actuator 610 is oscillated in a circular motion by a manual crank. Since the present invention does not propose improvements to the manual window opener 600, the manual window opener 600 can continue to utilize existing technology, and the specific structure of the manual window opener 600 will not be described in detail here.

[0036] Regardless of the structure of the manual window opener 600, its actuator 610 is engaged in the first inner groove 320, which provides a good positioning for the actuator 610. To avoid interference during manual window opening, in this embodiment, the actuator 610 is slidably connected to the first inner groove 320 to achieve a movable connection between the manual window opener 600 and the inner sash 300; alternatively, the actuator 610 is hingedly connected to the first inner groove 320 to achieve a movable connection between the manual window opener 600 and the inner sash 300.

[0037] It is understandable that the manual window opener 600 can also be set on the top of the sub-frame 200, but in order to facilitate use by people of all ages, in this embodiment, the manual window opener 600 is preferably set at the bottom of the sub-frame 200.

[0038] Since the window sash is primarily opened by the hand-cranked window opener 600, the handle 700 can be set on the sub-frame 200 and does not move with the window sash. The handle 700 is connected to a locking point 710 in the second inner ring groove 220. To improve sealing performance, each handle 700 drives at least two locking points 710. Correspondingly, a lock seat 720 is connected to the first inner ring groove 320. The number of lock seats 720 is consistent with the number of locking points 710, and the locking points 710 have a movement path that intersects with the corresponding lock seats 720. When the window sash and the sub-frame 200 are in the closed state, the user can control the position of the locking point 710 through the handle 700, so that the locking point 710 is locked to the lock seat 720. At this time, the relative position of the window sash and the sub-frame 200 is locked, and the window cannot be opened. When the window sash needs to be opened, the user can control the position of the locking point 710 by the handle 700 so that the locking point 710 moves away from the locking seat 720 . At this time, the relative position of the window sash and the sub-frame 200 is unlocked.

[0039] The above-mentioned structure and the design of the front and rear notches can provide good positioning for the hardware of the hand-cranked casement window and improve the installation standard. Compared with the previous installation method of directly screwing, the utility model solves the problems of inaccurate positioning and unstable installation of the hand-cranked casement window.

[0040] In some embodiments of the present invention, to further enhance the window's sealing performance, two handles 700 are provided on the sub-frame 200, one on each of the left and right sides of the sub-frame 200. The window locking mechanism includes a set of lock seats 720 and a set of lock points 710. When there are two handles 700, there are also two window locking mechanisms. Because both handles 700 and window locking mechanisms are installed on the left and right sides of the window, when the window is closed, both sides can be locked simultaneously, significantly enhancing the window's sealing performance, sound insulation, and anti-theft capabilities.

[0041] In some embodiments of the present invention, to prevent insects and mosquitoes, the sub-frame 200 is connected to a screen 800. The screen 800 is located behind the glass sash 400, that is, the screen 800 is closer to the indoor space. Because the window sash can be opened by a hand-cranked window opener 600, the user does not need to open the screen 800 when opening the window, maintaining continuous protection of the screen 800.

[0042] Furthermore, in order to facilitate cleaning of the screen window 800, the screen window 800 is detachably connected to the sub-frame 200. There are many detachable connection structures for the screen window 800. For example, the screen window 800 includes a screen window frame and a screen window body, and the screen window body is connected to the screen window frame through a key lock. When the user needs to remove the screen window body for cleaning, the key lock needs to be opened with a key to release the connection between the screen window body and the screen window frame; or, the sub-frame 200 is provided with an upper fastener and a lower fastener, and the screen window 800 is provided with an upper buckle hole and a lower buckle hole, so that the screen window 800 and the sub-frame 200 are detachably connected by a buckle.

[0043] In some embodiments of the present invention, to prevent water and wind from entering after the window is closed, the sub-frame 200 is provided with a sealing strip 230 that can abut against the inner sash 300. When the window is closed, the inner sash 300 abuts against the sealing strip 230 of the sub-frame 200, providing a certain degree of sealing performance. If the user further locks the window using the handle 700, the inner sash 300 will closely abut against the sealing strip 230 of the sub-frame 200, further strengthening the sealing performance and preventing water and wind from entering.

[0044] In other embodiments, the sealing strip 230 can also be provided on the inner fan 300. After closing the window, the sealing strip 230 of the inner fan 300 abuts against the sub-frame 200 to provide a certain sealing performance. If the user further locks the window through the handle 700, the sealing strip 230 of the inner fan 300 will be tightly abutted against the sub-frame 200, thereby enhancing the sealing performance and preventing water and air from entering.

[0045] In some embodiments of the present invention, to enhance thermal insulation, both the inner fan 300 and the sub-frame 200 feature a thermally insulated bridge structure 330. By adding a material with poor thermal conductivity, such as plastic or nylon insulation strips, to the aluminum alloy, the metal's rapid thermal conductivity is blocked. This design effectively blocks the rapid transfer of indoor and outdoor temperatures, reduces energy loss, and improves energy efficiency.

[0046] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the technical field without departing from the purpose of the present invention.
