Description

Technical Field

[0001] This invention relates to the field of fire safety equipment, and more particularly to a window sash support device suitable for casement windows. Background Technology

[0002] Currently available casement windows, such as CN216110313U, include a new type of casement window with good sound and heat insulation. This casement window comprises a main body structure with a movable structure on its front. The main body structure includes an outer frame, with a window frame movably connected inside the outer frame. Glass is fixedly connected to the inner side of the window frame. The outer frame includes a reinforcing layer, with a protective layer fixedly connected to its back. The glass comprises two glass panes and two safety base layers. A sound insulation layer is fixedly connected between the two glass panes, and a metal heat insulation layer is fixedly connected between the two safety base layers. An absorption layer is fixedly connected to the back of the metal heat insulation layer, and an anti-wear layer is fixedly connected to the back of the absorption layer. This new type of casement window with good sound and heat insulation not only improves the hardness of the glass but also blocks ultraviolet and infrared rays from sunlight, enhancing the glass's heat insulation effect.

[0003] Currently, due to space constraints, casement windows can only be supported by hinges located at the top and bottom of the sash. However, to enhance sound and heat insulation, window sashes are becoming increasingly heavier, causing the top and bottom hinges to deform under the weight of the sash. This reduces the smoothness of opening and closing the window and decreases its airtightness when closed. Furthermore, due to space limitations in the window frame and sash profiles, it is no longer possible to further increase the load-bearing capacity of the hinge linkages by thickening them. Summary of the Invention

[0004] In order to overcome the above-mentioned shortcomings of the prior art, the purpose of the present invention is to provide a window sash support device that assists the upper and lower hinges in bearing the weight of the window sash, reduces the hinge load and avoids deformation.

[0005] The technical solution adopted by this invention to solve its technical problem is:

[0006] A window sash support device suitable for casement windows includes a window sash support base, a support base, and a support rod. The lower end of the support rod is rotatably connected to the support base, and the upper end of the support rod is connected to the window sash support base. The window sash support base is disposed on the window sash, and the support base is disposed on the window frame.

[0007] Specifically, the window sash support and the window sash bracket can be interchanged without changing their function, and they can still achieve the same effect of supporting the window sash from the window frame.

[0008] Furthermore, when the support base is located on the axis of rotation of the window sash during opening and closing, and the lower end of the support rod is also located on this axis, the upper end of the support rod can be fixedly connected to the window sash support. At this time, when the window is opened and closed, the support rod rotates as a whole on an inverted conical arc surface, and the relative distance between the window sash support and the support base remains unchanged.

[0009] By adopting the above technical solution, the support seat installed on the window frame supports the window sash through the support rod and the window sash support seat, reducing the force on the hinge of the window sash, reducing the hinge load and avoiding deformation.

[0010] As an improvement, when the window sash and window frame are closed, the support rod tilts upwards from the bottom towards the window frame, moving away from the window sash and closer to it. Specifically, when the window sash and window frame are closed, the distance from the bottom of the support rod to the side of the window sash is less than the distance from the top of the support rod to the side of the window sash.

[0011] By adopting the above technical solution, when the window sash is closed, the support rod not only supports the window sash in the vertical direction but also drives the window sash to exert force towards the window frame in the horizontal direction, further improving the window closing force during a fire and enhancing safety.

[0012] As an improvement, the support base and / or window sash support base are provided with a sliding channel; the sliding channel is provided with the load-bearing member and the supporting elastic member, one end of the supporting elastic member is fixedly connected to the window sash support base / support base, and the other end is connected to the load-bearing member; the load-bearing member can slide up and down within the sliding channel; the support rod is elastically supported and connected to the support base and / or window sash support base through the load-bearing member and the supporting elastic member.

[0013] Specifically, taking a window sash support as an example, the window sash support includes a housing and a supporting elastic element (spring) and a load-bearing element arranged from top to bottom inside the housing. The upper end of the spring is fixedly connected to the housing, and the lower end is connected to the top of the load-bearing element. The support rod extends into the housing and connects to the bottom of the load-bearing element. In this way, the upper end of the support rod can move up and down within a certain range within the housing, and at all times maintains a supporting force on the housing and window sash through the load-bearing element-spring.

[0014] The aforementioned technical solution arose because if the support base and the lower section of the support rod are not located on the axis of rotation for the window sash during opening and closing, the relative distance between the window sash support and the support base changes during the opening and closing process. This change can cause the window to jam and close unevenly, or even obstruct the normal opening and closing process. Therefore, the design incorporates a certain sliding gap between the support rod and the window sash support, and an elastic element provides a certain elastic tension when the support element slides up and down. This ensures smooth window opening and closing even when the support base is installed off-axis. The elastic element in this design is essentially the same component as the energy storage spring in the window closing device described below.

[0015] By adopting the above technical solution, the distance between the support base and the window sash support base changes during the opening and closing process. The elastic support element can alleviate the problem of the window opening and closing being difficult due to the change in the distance between the two ends of the support rod.

[0016] As an improvement, a limiting bolt is also provided on the support base and / or window sash support. The bearing member has a vertically arranged limiting groove that matches the limiting bolt. The limiting bolt passes through the sliding channel and the limiting groove and is fixed to the window sash / frame. In this way, the bearing member is restricted by the limiting bolt and can only slide up and down within the range allowed by the limiting groove. When the support rod moves upward and causes the bearing member to move to the highest point within the range, the support rod becomes supported through the path of bearing member-limiting bolt-window sash / frame. This protects the elastic support member from excessive compression and failure. At the same time, the limiting bolt also makes the up and down sliding process of the bearing member more stable, and the bearing member and elastic support member are less prone to deformation.

[0017] As an improvement, the support base and / or window sash support base are provided with adjusting bolts that abut against the load-bearing member. The adjusting bolts are rotatably connected through screw holes on the support base and / or window sash support base, and the height of the load-bearing member can be adjusted by rotating the adjusting bolts.

[0018] As an improvement, the support rod is a telescopic structure and has a supporting elastic element inside. The support rod extends to both ends under the action of the supporting elastic element to support the window sash support seat.

[0019] By adopting the above technical solution, the distance between the support base and the window sash support base changes during the opening and closing process. The support rod can elastically extend and retract to change its length, which can alleviate the problem of the window opening and closing being difficult due to the change in the distance between the two ends of the support rod.

[0020] As an improvement, the connection end between the support rod and the support seat and / or the window sash support seat is spherical, and the support seat and / or the window sash support seat is provided with a bearing member that matches the spherical connection end. The support rod and the support seat and / or the window sash support seat are rotatably supported and connected through the spherical connection end and the bearing member.

[0021] By adopting the above technical solution, the rotation of the end of the support rod is smoother during the opening and closing of the window.

[0022] As an improvement, the window sash support is a window closing device connected to the upper hinge. The window closing device includes an actuation mechanism and a transmission mechanism. The transmission mechanism is connected to the upper hinge of the window sash. The actuation mechanism includes an energy storage element and a temperature-sensing actuation element. The temperature-sensing actuation element prevents the energy storage element from pushing the transmission mechanism. When the temperature is higher than the preset temperature of the temperature-sensing actuation element, the temperature-sensing actuation element releases its obstruction of the energy storage element. The energy storage element then pushes the transmission mechanism, causing the upper hinge of the window sash to move and close the window sash.

[0023] By adopting the above technical solution, when the surrounding environment is not hot, the temperature-sensing actuator of the window closing device blocks the energy storage device, allowing the window to open and close normally. When the surrounding environment is hot, the temperature-sensing actuator releases its obstruction of the energy storage device, and the energy storage device pushes the transmission mechanism, which drives the upper hinge of the window sash to move and thus close the window sash.

[0024] As an improvement, the window closing device has a housing with a snap-fit ​​groove; the energy storage component is an energy storage spring; the temperature-sensing actuation component includes a snap-fit ​​wheel and a temperature-sensing glass ball; the snap-fit ​​wheel is rotatably connected to the housing, and the snap-fit ​​wheel has a limiting protrusion that matches the snap-fit ​​groove; the snap-fit ​​wheel is blocked by the temperature-sensing glass ball, which snaps the limiting protrusion into the snap-fit ​​groove.

[0025] As an improvement, the temperature-sensitive actuating component is provided with a locking wheel, a blocking component, and a temperature-sensitive glass ball arranged from top to bottom; the locking wheel is provided with an outwardly extending locking tongue and a limiting protrusion, the blocking component abuts against the locking tongue, and the limiting protrusion is fixed to the locking groove by blocking the movement of the locking tongue.

[0026] As an improvement, the temperature-sensitive starter is provided with a locking wheel, a blocking member, and a temperature-sensitive glass ball arranged from top to bottom; the locking wheel is provided with an outwardly extending locking tongue, and the locking tongue has a limiting protrusion on the side facing the locking groove, and the other side abuts against the blocking member.

[0027] By adopting the above technical solution, the temperature-sensing glass ball normally lifts the blocking component, and the side of the blocking component abuts against the latch, fixing the limiting protrusion in the locking groove, thus preventing the energy storage spring from pushing the temperature-sensing starter upward to drive the transmission mechanism. Using a purely mechanical structure for temperature-sensing start offers better stability and reliability compared to electronic components, and it can still operate reliably even after long periods of non-use.

[0028] As an improvement, the blocking member and the latch are abutted by an inclined surface provided on the blocking member or the latch, the inclined surface causing the latch to maintain a downward pushing force on the blocking member.

[0029] As an improved solution, the transmission mechanism includes a transmission shaft and a transmission slider; the upper end of the transmission shaft is connected to the upper hinge of the window sash, the lower side of the transmission shaft is provided with a steering protrusion, and the side of the transmission slider is provided with a spiral groove that matches the steering protrusion. The steering protrusion is slidably disposed in the spiral groove. When the steering protrusion moves from the top end to the bottom end of the spiral groove, it drives the upper hinge of the window sash to change from the open state to the closed state.

[0030] By adopting the above technical solution, when the energy storage spring pushes the transmission slider upward, the spiral groove moves upward, causing the steering protrusion to rotate, thereby rotating the transmission shaft along the vertical axis, which in turn drives the upper hinge of the window sash to rotate and close the window sash. The use of a purely mechanical structure for temperature-sensitive start-up offers better stability and reliability compared to electronic components, and it can still operate reliably even after long periods of non-use.

[0031] As an improvement, the side of the window sash is provided with a clamping groove that matches the window sash support, and the window sash support is fixedly connected to the window sash through the clamping groove.

[0032] Compared with the prior art, the beneficial effects of the present invention are:

[0033] The support bracket installed on the window frame supports the window sash through the support rod and the window sash support bracket, reducing the force on the upper and lower hinges of the casement window sash, reducing the hinge load and preventing deformation.

[0051] Implementation Case 1:

[0052] As attached Figure 1-6 As shown, a temperature-sensitive window closer that also supports the weight of the window sash 5 includes a window sash support 3, a support base 1, and a support rod 2. The lower end of the support rod 2 is connected to the support base 1, and the upper end of the support rod 2 is connected to the window sash support 3. The window sash support 3 is mounted on the window sash 5 and is connected to the upper hinge 4 of the window sash 5. The support base 1 is mounted on the window frame 6.

[0053] The support seat 1 installed on the window frame 6 supports the window sash 5 through the support rod 2 and the window sash support seat 3, reducing the force on the hinge 4 on the window sash 5, reducing the hinge load and avoiding deformation.

[0054] When the window sash 5 and window frame 6 are closed, the support rod 2 tilts upwards from the bottom towards the window sash 5 and towards the window frame 6. Specifically, when the window sash 5 and window frame 6 are closed, the distance from the bottom of the support rod 2 to the side of the window sash 5 is less than the distance from the top of the support rod 2 to the side of the window sash 5.

[0055] When the window sash 5 is closed, the support rod 2 supports the window sash 5 in the vertical direction while also driving the window sash 5 to exert force towards the window frame 6 in the horizontal direction, further improving the window closing force in case of fire and enhancing safety.

[0056] The support base 1 and / or window sash support 3 are provided with a support elastic element that matches the support rod 2, and the support rod 2 is levitated to the support base 1 and / or window sash support 3 through the support elastic element.

[0057] During the opening and closing of the window, the distance between the support base 1 and the window sash support base 3 changes. The elastic support can alleviate the problem of the window not opening smoothly due to the change in the distance between the two ends of the support rod 2.

[0058] The support rod 2 is a telescopic structure, and a support elastic element is provided inside the support rod 2. The support rod 2 extends to both ends under the action of the support elastic element to support the window sash support seat 3.

[0059] During the opening and closing of the window, the distance between the support base 1 and the window sash support base 3 changes. The support rod 2 can elastically extend and retract to change its length, which can alleviate the problem of the window not opening and closing smoothly caused by the change in the distance between the two ends of the support rod 2.

[0060] The connection end between the support rod 2 and the support base 1 and / or the window sash support base 3 is spherical. The support base 1 and / or the window sash support base 3 is provided with a bearing member 7 that matches the spherical connection end. The support rod 2 and the support base 1 and / or the window sash support base 3 are rotatably supported and connected through the spherical connection end and the bearing member 7.

[0061] The end of the support rod 2 rotates more smoothly during the opening and closing of the window.

[0062] The window sash support 3 includes an actuation mechanism and a transmission mechanism. The transmission mechanism is connected to the upper hinge 4 of the window sash 5. The actuation mechanism includes an energy storage component and a temperature-sensing actuation component. The temperature-sensing actuation component prevents the energy storage component from pushing the transmission mechanism. When the temperature is higher than the preset temperature of the temperature-sensing actuation component, the temperature-sensing actuation component releases its obstruction of the energy storage component. The energy storage component then pushes the transmission mechanism, causing the upper hinge 4 of the window sash 5 to move and close the window sash 5.

[0063] When the surrounding environment is not hot, the temperature-sensing actuator of the window sash support 3 blocks the energy storage device, allowing the window to open and close normally. When the surrounding environment is hot, the temperature-sensing actuator releases its obstruction of the energy storage device, and the energy storage device pushes the transmission mechanism, causing the upper hinge 4 of the window sash 5 to move and thus close the window sash 5.

[0064] The window sash support 3 is provided with a housing 8, and the housing 8 is provided with a snap-fit ​​groove 9; the energy storage component is an energy storage spring 10, and the temperature sensing actuation component includes a snap-fit ​​wheel 11 and a temperature sensing glass ball 12. The snap-fit ​​wheel 11 is rotatably connected to the housing 8, and the snap-fit ​​wheel 11 is provided with a limiting protrusion 19 that matches the snap-fit ​​groove 9; the snap-fit ​​wheel 11 is blocked by the temperature sensing glass ball 12, and the limiting protrusion 19 is snapped into the snap-fit ​​groove 9.

[0065] The temperature-sensitive actuating component is provided with a locking wheel 11, a blocking component 13, and a temperature-sensitive glass ball 12 arranged from top to bottom. The locking wheel 11 is provided with an outwardly extending locking tongue 14. The locking tongue 14 is provided with a limiting protrusion 19 on the side facing the locking groove 9, and abuts against the blocking component 13 on the other side.

[0066] Normally, the temperature-sensitive glass bulb 12 lifts the blocking member 13, with the side of the blocking member 13 abutting against the latch 14, fixing the limiting protrusion 19 within the locking groove 9, preventing the energy storage spring 10 from pushing the temperature-sensitive starter upwards to drive the transmission mechanism. When the ambient temperature rises to a certain level due to a fire, the temperature-sensitive glass bulb 12 shatters and breaks, the blocking member 13 loses its bottom support and falls, the latch 14 loses the obstruction of the blocking member 13 on one side, the locking wheel 11 loosens, and the limiting protrusion 19 can no longer remain within the locking groove 9. The energy storage spring 10 then pushes the entire temperature-sensitive starter upwards, applying pressure to the transmission mechanism. This purely mechanical structure achieves temperature-sensitive start-up, offering better stability and reliability compared to electronic components, and it can still operate reliably even after long periods of non-use.

[0067] The transmission mechanism includes a transmission shaft 15 and a transmission slider 17. The upper end of the transmission shaft 15 is connected to the upper hinge 4 of the window sash 5. The lower side of the transmission shaft 15 is provided with a steering protrusion 16. The side of the transmission slider 17 is provided with a spiral groove 18 that matches the steering protrusion 16. The steering protrusion 16 is slidably disposed in the spiral groove 18. When the steering protrusion 16 moves from the top end to the bottom end of the spiral groove 18, it drives the upper hinge 4 of the window sash 5 to change from the open state to the closed state.

[0068] When the energy storage spring 10 pushes the transmission slider 17 upward, the spiral groove 18 moves upward, causing the steering protrusion 16 to rotate, thereby causing the transmission shaft 15 to rotate along the vertical axis, which in turn drives the upper hinge 4 of the window sash 5 to rotate, closing the window sash 5. The use of a purely mechanical structure for temperature-sensitive start-up offers better stability and reliability compared to electronic components, and it can still operate reliably even after long periods of non-use.

[0069] The principle by which the window sash support, bracket, and support rod support the window sash is as follows:

[0070] The support base is fixedly installed on the side wall of the window frame facing the window sash, and the window sash support base is fixedly installed on the side wall of the window sash facing the window frame. One end of the support rod is located on the upper part of the support base, and the other end is located on the bottom of the window sash support base. In this way, a new support method is added between the window frame and the window sash through the connection and support relationship of window frame-support base-support rod-window sash support base-window sash. This breaks the current situation where casement windows can only be supported by the upper and lower hinges, and solves the problem that the existing upper and lower hinges have low load-bearing capacity and cannot be supplemented with additional support methods or have their hinge material thickness increased to improve load-bearing capacity.

[0071] Specifically, because the two ends of the support rod are spherical, and the window sash support and base have matching load-bearing components, the connecting rod can adapt to the positional rotation of the window frame and window sash during the opening and closing of the window and maintain support. At the same time, the load-bearing components are elastically suspended connected to the window sash support and base, which ensures that the support rod is always in contact with the window sash support and base, improving operational stability.

[0072] The aforementioned technical solution arose because if the support base and the lower section of the support rod are not located on the axis of rotation when the window sash is opened and closed, the relative distance between the window sash support and the support base will change during the opening and closing process. This change can cause the window to jam and become difficult to close, or even obstruct the normal opening and closing process. Therefore, the design allows the support rod and the window sash support to be connected in a flexible support manner to ensure that the window sash can still complete the opening and closing action and maintain smooth operation even after the support device is installed.

[0073] The supporting elastic element here and the energy storage spring of the window closing device mentioned below are essentially the same part.

[0074] Furthermore, the bottom of the support base is equipped with an adjusting bolt that can be rotated to finely adjust the vertical height. The top of the adjusting bolt abuts against the bearing member. When the adjusting bolt is rotated to raise it, the bearing member is pushed upward, increasing the support force of the support rod on the window sash support base.

[0075] The working principle of the window closing mechanism connected to the upper hinge, which is added inside the window sash support, is as follows:

[0076] Normally, the temperature-sensitive actuator and the window sash support are locked together, and the energy storage component (such as a spring) is blocked by the temperature-sensitive actuator to maintain its stored power. Since the transmission mechanism is not subjected to an upward pushing force, it does not affect the rotation of the upper hinge when opening and closing the window, and the casement window can be opened and closed normally.

[0077] When a fire occurs, the temperature-sensing glass bulb inside the temperature-sensing actuator shatters due to heat, causing the locking wheel to lose its support. This results in the locking wheel's limiting protrusion disengaging from the locking groove, and the temperature-sensing actuator releasing its lock from the window sash support. Driven by the energy-storing spring, the temperature-sensing actuator is pushed upwards, applying an upward thrust to the transmission mechanism.

[0078] The lowest transmission slider of the transmission mechanism moves upward under the action of thrust. Since the transmission shaft cannot move up and down, the steering protrusion on the side of the transmission shaft rotates horizontally under the action of the spiral groove of the transmission slider, causing the entire transmission shaft to rotate. The top of the transmission shaft is connected to the upper hinge, so the upper hinge rotates in the direction of closing the window, thereby closing the window sash.

[0079] This technical solution also has the following advantages:

[0080] 1) Since it adopts a mechanical structure, the window closing action will not be affected regardless of whether there is a power outage at the fire scene, and its reliability is better than that of window closers that use induction, activation and power source.

[0081] 2) The supporting structure and the window closing structure are both integrated and compressed into the narrow space of the window sash and the side of the window frame near the hinge, so as not to affect the normal opening and closing of the window or obstruct the view.

[0082] In summary, those skilled in the art, after reading this invention document, can make various other corresponding modifications to the technical solutions and concepts based on this invention without creative mental effort. Different application scenarios all fall within the scope of protection of this invention.
