Description

Technical Field

[0001] The utility model belongs to the technical field of doors and windows, and particularly relates to a tilt-down window. Background Art

[0002] Tilt-and-turn windows feature a unique opening mechanism. During use, the lower sash remains stationary while the upper portion tilts toward the interior, creating a compact vent. This allows for natural ventilation while effectively preventing rainwater and dust from entering the room. Because the opening angle is limited, typically only a gap at the top is left for ventilation, without occupying interior space. This makes them ideal for everyday use, especially when it's necessary to keep the window open without disrupting indoor activities. The limited opening angle of tilt-and-turn windows reduces safety risks for families with children, such as those who might accidentally open the window.

[0003] However, in actual application, inward-opening and tilting windows also expose some shortcomings, especially when dealing with large windows and high-position windows, the challenges are particularly prominent.

[0004] On the one hand, the significantly increased weight and size of larger tilt-and-turn windows make manual opening and closing extremely difficult. Users must exert considerable force to overcome the weight of the sash and the additional friction caused by its larger size. Furthermore, due to the operational difficulties, users may damage the window hardware or frame due to excessive force or improper operation, which not only increases repair costs but also potentially affects the window's sealing and service life.

[0005] On the other hand, when tilt-and-turn windows are installed at high locations, such as in high-rise buildings or skylights at the top of a room, users also face difficulty opening and closing them. Due to height restrictions, users cannot directly reach and operate the window handle or transmission mechanism, making it impossible to open or close the window. This not only affects the normal use of the window, but also may lead to a decrease in indoor air quality due to the inability to open the window for ventilation in time, and even pose a safety hazard. Utility Model Content

[0006] The primary purpose of the present invention is to solve at least one of the above problems and provide a tilt-down window.

[0007] In order to meet one of the purposes of the utility model, a tilt-down window is provided, comprising a window frame, a window sash, a hinge assembly and a window opening assembly, wherein the hinge assembly is connected to the bottom of the window frame and the bottom of the window sash, respectively, and the window opening assembly comprises a linear drive and a traction rope, wherein the linear drive is arranged on the window frame, one end of the traction rope is connected to the linear drive, and the other end is connected to the window sash, and the linear drive is used to drive the traction rope to move so as to realize the opening and closing of the window sash relative to the window frame.

[0008] Furthermore, the window frame includes a top beam, the top beam includes a first surface and a second surface facing oppositely, a through hole is provided on the top beam, the first surface faces the window sash, the linear drive is arranged on the second surface, and the traction rope passes through the through hole from the second surface and is connected to the top of the window frame.

[0009] Specifically, a fixing piece is provided on the top of the window sash, and the traction rope is fixedly connected to the fixing piece.

[0010] In one embodiment, the tilt-down window is provided with two window opening assemblies, and the linear drives of the two window opening assemblies are both distributed on the top beam.

[0017] Compared with the prior art, the present invention has many advantages, including but not limited to:

[0018] Traditional tilt-down windows rely on manual operation, such as rotating a handle or sliding the sash, which limits user convenience to a certain extent. Especially when the sash is large or heavy, manual operation often seems inadequate and may even pose a safety hazard. The tilt-down window of the present invention achieves automated opening and closing of the tilt-down window by introducing a linear actuator. By controlling the operation of the linear actuator, the tilt-down window can be easily opened and closed. This not only greatly reduces the difficulty of operation, but also improves the accuracy and stability of the operation, allowing users to easily cope with different scenarios.

[0019] In addition to ease of operation, this new tilt-in window enhances the user experience in several ways. First, automated operation reduces direct contact between the user and the window sash, reducing safety risks associated with improper operation or sash failure. Second, the introduction of a linear actuator makes the window opening and closing process smoother and quieter, reducing noise pollution and improving living comfort. Furthermore, automated tilt-in windows can be integrated with smart home systems to enable remote control, timed opening, and other functions, further enriching the user experience.

[0029] The utility model provides a tilt-down window, which can automatically open and close the window with the assistance of its window opening component, so as to improve the intelligence of the tilt-down window and enhance the user experience.

[0030] In a typical embodiment of the present invention, Figure 1 and Figure 3 The tilt-down window 100 includes a window frame 110, a window sash 120, a hinge assembly and a window opening assembly.

[0031] The window sash 120 includes a sash frame 121 and a glass sheet disposed within the sash frame 121. The hinge assembly includes a pair of hinges 130. The sash frame 121 is movably connected to the window frame 110 via the pair of hinges 130. Specifically, the hinge 130 includes a first connecting end 131 and a second connecting end 132. The first connecting end 131 is connected to one side of the bottom of the window frame 110, and the second connecting end 132 is connected to one side of the bottom of the sash frame 121.

[0032] The pair of hinges 130 are respectively arranged on both sides of the bottom of the sash frame 121, so that when the window frame 110 and the sash frame 121 are movably connected by the pair of hinges 130, the sash frame 121 can be tilted relative to the window frame 110, that is, the sash frame 121 can be tilted inward relative to the window frame 110. It can be understood that the window sash 120 can be tilted inward relative to the window frame 110.

[0033] Combine Figure 2 and Figure 5 The window opening assembly includes a linear driver 141, a traction rope 142, and a control unit 143. The linear driver 141 is used to convert rotational motion into linear motion. The control unit 143 is electrically connected to the linear driver 141 and is used to control the operation of the linear driver 141. The linear driver 141 is installed on the window frame 110. One end of the traction rope 142 is connected to the output end of the linear driver 141, and the other end of the traction rope 142 is connected to the sash frame 121 of the window sash 120.

[0034] In this embodiment, it is recommended that the traction rope 142 is a chain, but this should not be understood as a limitation of the present invention. The chain can withstand a large force, is not easy to be damaged by fatigue, and is wear-resistant and can be used for a long time.

[0035] Combine Figure 1 and Figure 2 The control unit 143 controls the linear actuator 141 to operate, and the linear actuator 141 drives the traction rope 142 to move. The traction rope 142 drives the window sash 120 to move, thereby moving the window sash 120 relative to the window frame 110, thereby opening / closing the tilt-in window 100. Specifically, when the tilt-in window 100 is closed but needs to be opened, the control unit 143 controls the linear actuator 141 to move in a first direction to release the traction rope 142 outward. During the release of the traction rope 142, the window sash 120 tilts outward relative to the window frame 110, that is, the window sash 120 moves relatively away from the window frame 110, thereby opening the tilt-in window 100. When the tilt-down window 100 is opened but needs to be closed, the control unit 143 controls the linear drive 141 to move in a second direction, where the first direction and the second direction are opposite to each other, so as to retract the traction rope 142. During the retraction process of the traction rope 142, the window sash 120 is relatively close to the window frame 110, thereby achieving the closure of the tilt-down window 100.

[0036] In this embodiment, combined with Figure 1 and Figure 4The window frame 110 includes a top beam 111 on the top. The top beam 111 includes a first surface 1111 and a second surface 1112. The first surface 1111 and the second surface 1112 face opposite directions, with the first surface 1111 facing the window sash 120. The top beam 111 also includes a through hole 1113, which extends from the first surface 1111 to the second surface 1112. The linear actuator 141 is disposed on the second surface 1112 of the top beam 111. The traction rope 142 passes through the through hole 1113, so that the linear actuator 141 drives the traction rope 142 to control the opening and closing of the window sash 120.

[0037] Combine Figure 1 The window opening assembly further includes a housing 144 disposed on the second surface 1112 of the top beam 111. The linear actuator 141 is disposed within the housing 144 to protect the linear actuator 141. The linear actuator 141 drives the pull rope 142 into the housing 144. When the tilt window 100 is closed, the pull rope 142 enters the housing 144, thereby concealing the pull rope 142 and enhancing the aesthetics of the tilt window 100. In this embodiment, the housing 144 is fixed to the second surface 1112. For example, the housing 144 may be bonded to the second surface 1112, or alternatively, the housing 144 may be screwed to the top beam 111.

[0038] In one embodiment, combined Figure 3 A fixing member 112 is provided on the top of the sash frame 121, and one end of the traction rope 142 is connected to the fixing member 112 so that the force acting on the traction rope 142 can be transmitted to the window sash 120. In this embodiment, it is recommended that the fixing member 112 is a hook or a hanging ring, but this should not be understood as a limitation of the present invention.

[0039] In an exemplary embodiment of the present invention, the tilt-down window 100 includes two window opening assemblies, each of which has a linear actuator 141 located on either side of the second surface 1112 of the top beam 111. In this embodiment, it is recommended that the two linear actuators 141 be symmetrical about the central axis of the second surface 1112, but this should not be construed as a limitation of the present invention. In this embodiment, the two window opening assemblies share a common control unit 143 to save components and facilitate synchronous control of the two linear actuators 141.

[0040] The two traction ropes 142 of each of the two window opening assemblies are connected to the sash frame 121 of the window sash 120. The two traction ropes 142 are connected to both sides of the top of the sash frame 121, so that the window sash 120 can be stably connected to the window frame 110 under the action of the two traction ropes 142. Moreover, under the action of the two traction ropes 142, a stable force can be applied to the window sash 120, so that the window sash 120 can move stably relative to the window frame 110, and the tilt-down window 100 can be stably opened and closed.

[0041] In one embodiment, the control unit 143 is electrically connected to an external control device. The external control device outputs control commands to the control unit 143. Upon receiving the control commands, the control unit 143 controls the linear actuator 141 to operate, thereby opening and closing the tilt-down window 100. In this embodiment, the control unit 143 is connected to the external control device via a wired or wireless connection. In this embodiment, the external control device is preferably a mobile phone, a remote control, or a control panel, but this is not to be construed as a limitation of the present invention.

[0042] In one embodiment, combined Figure 1 and Figure 3 The tilt-down window 100 further includes a pair of wind braces 150, which are disposed on either side of the sash frame 121 of the window sash 120 to support the window sash 120. A first end 151 of the wind brace 150 is pivotally connected to the window frame 110, and a second end 152 is movably connected to the sash frame 121. A locking structure (not shown) is provided on the sash frame 121. The locking structure includes a latching portion, and the second end 152 of the wind brace 150 is disposed in the locking structure.

[0043] When the tilt-down window 100 is opened to the maximum extent, the second end 152 of the wind brace 150 will enter the locking position, thereby limiting the movement of the second end 152, so that the window frame 110 can support the window sash 120 through the wind brace 150, and there is no need for the traction rope 142 to drag the window sash 120 under force, so as to avoid the traction rope 142 dragging the window sash 120 after the tilt-down window 100 is fully opened, thereby reducing fatigue damage to the traction rope 142 and extending the service life of the traction rope 142.

[0044] In one embodiment, the window opening assembly further includes a power supply. In this embodiment, the power supply is an external power supply. The control unit 143 is connected to the external power supply via a cable to supply power to the window opening assembly through the external power supply.

[0045] In another embodiment, the window opening assembly further includes a battery, which is used to power the control unit 143. When the external power supply is out of power, the window opening assembly can be powered by the battery so that the tilt-down window 100 can be opened and closed normally.

[0046] In summary, the tilt-down window of the present invention can be opened and closed automatically with the cooperation of the linear drive and the traction rope, without the need for manual operation, thereby improving the user experience.
