[0038] See also Figure 1-8As shown, the present embodiment discloses a top-hung window system which is self-closing under strong wind pressure, comprising: a window frame 1, a window sash 2, a friction limiter 3 and an elastic member 4; the top end of the window sash 2 is rotatably connected to the window frame 1; the two ends of the friction limiter 3 are respectively connected to the window frame 1 and the window sash 2; the friction limiter 3 comprises: a support rod 31, a slider 32 and a slide rail 33; the slide rail 33 is connected to the window frame 1, the slider 32 is slidably connected to the slide rail 33, and frictionally cooperates with the slide rail 33, and the two ends of the support rod 31 are respectively rotatably connected to the slider 32 and the window sash 2; the elastic member 4 is connected to the edge of the window sash 2 and extends to the outside of the window sash 2, and the window frame 1 is provided with a lock seat 11 corresponding to the elastic member 4.
[0039] There is a certain friction coefficient between the slider 32 and the slide rail 33 of this embodiment, so that the window sash 2 can maintain a certain angle with the window frame 1 through the support rod 31 when in the open state; when the wind pressure on the window sash 2 exceeds the friction coefficient of the friction limiter 3, the slider 32 slides relative to the slide rail 33, thereby reducing the angle between the support rod 31 and the window frame 1, and the window sash 2 approaches the window frame 1 under the action of its own weight. When the elastic member 4 at the edge of the window sash 2 contacts the window frame 1, it moves away from the window frame 1 under the action of its own elasticity until the window sash 2 is in contact with the window frame 1, and the elastic member 4 rebounds into the lock seat 11, realizing the automatic closing and locking of the window sash 2, avoiding rainwater from entering the room, so that the top-hung window system can prevent wind and rain from damaging indoor property.
[0040] In one embodiment, the elastic member 4 includes: a fixed block 41, a latch 42, a spring 43 and a connecting block 44; the fixed block 41 is connected to the edge of the window sash 2; the connecting block 44 is connected to the side of the fixed block 41 away from the lock seat 11, and the side of the connecting block 44 close to the fixed block 41 is provided with a receiving groove 441; the spring 43 and the latch 42 are inserted into the receiving groove 441, one end of the spring 43 is connected to the receiving groove 441, and the other end is connected to the latch 42; the latch 42 penetrates the fixed block 41; and the lock seat 11 is arranged corresponding to the latch 42. One end of the latch 42 away from the center of the window sash 2 extends to the outside of the window sash 2, perpendicular to the edge of the window sash 2. When the window sash 2 is close to the window frame 1, the latch 42 abuts against the window frame 1 and gradually moves toward the center of the window sash 2, so that the spring 43 is compressed by the thrust of the latch 42. When the window sash 2 moves to the point where the latch 42 is facing the lock seat 11, the spring 43 is released to drive the latch 42 into the lock seat.
[0041] In one embodiment, a handle 442 is provided at one end of the connection block 44 away from the lock seat 11, and the connection block 44 is slidably connected to the fixed block 41. The handle 442 is located on the side of the connection block 44 close to the center of the window sash 2. The connection block 44 is moved toward the center of the window sash 2 by lifting the handle 442, and the spring 43 is deformed until the latch 42 completely leaves the lock seat 11, and the window sash 2 can be pushed outward. After the window sash 2 is away from the window frame 1, the handle 442 is released to complete the opening action of the window sash 2. The connection block 44 can be sleeved outside the fixed block 41, or inserted into the fixed block 41, and the connection block 44 moves in the direction where the latch 42 extends. In this embodiment, the connection block 44 and the fixed block 41 are frictionally connected. In practical applications, the friction coefficient between the connection block 44 and the fixed block 41 can be adjusted so that the friction force between the connection piece and the fixed block 41 is greater than the elastic force of the spring 43, so as to prevent the connection block 44 from moving when the window sash 2 is automatically closed and the spring 43 is deformed, causing the spring 43 to loosen and it is difficult to provide sufficient power for the latch 42 to rebound. It is understandable that in other embodiments, the connection block 44 and the fixed block 41 are both provided with corresponding locking structures, so that the connection block 44 and the fixed block 41 are locked. When the window sash 2 needs to be opened, the connection block 44 is moved after contacting the locking structure and the window sash 2 is pushed out.
[0042] In one embodiment, the lock seat 11 comprises: a base 111 and a block 112; the base 111 is connected to the window frame 1, the block 112 is connected to the side of the base 111 close to the window sash 2, and a lock slot 113 is formed between the base 111 and the block 112; a guide surface 1121 is provided on the side of the block 112 close to the window sash 2; the guide surface 1121 is inclined from the side of the base 111 close to the window sash 2 to the side away from the window sash 2 and the lock slot 113. The guide surface 1121 is used to guide the bolt 42 to move from the lock seat 11 to the closing direction of the window sash 2. When the window sash 2 is close to the window frame 1, the end of the bolt 42 away from the handle 442 contacts the guide surface 1121 and moves along the guide surface 1121, so that the spring 43 is compressed until the bolt 42 enters between the block 112 and the base 111, at which time the spring 43 is released, driving the bolt 42 to enter the lock seat 11 through the lock slot 113. When the latch 42 is located in the lock seat 11, the window sash 2 is closed and locked, and rainwater cannot enter the room through the top-hung window. The plug prevents the latch 42 from moving toward the side close to the window sash 2, preventing the wind from pushing the window sash 2 open when the indoor or convection wind pressure is large, thereby ensuring the safety and reliability of the top-hung window system.
[0043] In one embodiment, the window frame 1 includes: an upper frame 12, a lower frame 13 and two side frames 14; the upper frame 12 and the lower frame 13 are symmetrically arranged, the two side frames 14 are symmetrically arranged, and the two ends of the side frames 14 are respectively connected to the upper frame 12 and the lower frame 13; the upper frame 12, the lower frame 13 and the two side frames 14 are enclosed to form a rectangular frame structure. The top end of the window sash 2 is rotatably connected to the upper frame 12.
[0044] In one embodiment, the window sash 2 includes: a sash frame 21 and a connecting frame 22; the top of the sash frame 21 is rotatably connected to the upper frame 12; the connecting frame 22 is connected to the side of the sash frame 21 close to the window frame 1, and the length and width of the connecting frame 22 are both smaller than the length and width of the sash frame 21; the connecting frame 22 is used to enter or leave the window frame 1, and the sash frame 21 is used to install the glass 23; the connecting frame 22 includes: an upper profile 221, a lower profile 222 and two vertical profiles 223; the upper profile 221 and the lower profile 222 are symmetrically arranged, and the two vertical profiles 223 are symmetrically arranged, and the two ends of the vertical profile 223 are respectively connected to the upper profile 221 and the lower profile 222; the upper profile 221, the lower profile 222 and the two vertical profiles 223 are enclosed to form a rectangular frame structure. The edge of the window frame 1 is a connecting frame 22, and one end of the support rod 31 away from the slide rail 33 is connected to the outer wall of the connecting frame 22; the fixing block 41 is connected to the side of the lower profile away from the lock seat 11, and the elastic member 4 is connected to the edge of the connecting frame 22 close to the window frame 1. The elastic member 4 vertically penetrates the lower profile 222, and the end of the latch 42 close to the lock seat 11 is located at the bottom of the lower profile 222, that is, the side of the lower profile 222 close to the window frame 1 and attached to the window frame 1, and the connecting block 44 is located on the side of the lower profile 222 close to the upper profile 221.
[0045] In this embodiment, the elastic member 4 is connected to the bottom edge of the window sash 2. Specifically, the elastic member 4 is connected to the lower profile 222, and the lock seat 11 is arranged on the lower frame 13. It is convenient for the user to lift the handle 442 to open the window sash 2, and the latch 42 can enter the lock seat 11 more smoothly and quickly through the elastic force of the spring 43 and the effect of its own gravity. It can be understood that in other embodiments, the elastic member 4 is connected to the side wall of the window sash 2, that is, the elastic member 4 is connected to the vertical profile 223, and in this case, the lock seat 11 is arranged on the side frame 14.
[0046] In one embodiment, the window frame 1 is provided with a slide groove 15, and the slide rail 33 is located in the slide groove 15 and connected to the slide groove 15. The setting of the slide groove 15 allows the slide rail 33 to be embedded in the window frame 1, reducing the gap between the window sash 2 and the window frame 1, so that the window sash 2 can fit closely with the window frame 1.
[0047] In one embodiment, the friction limiter 3 further includes: a mounting block 34 and an adjuster 35; the mounting block 34 is connected to the edge of the window sash 2, and the end of the support rod 31 away from the slider 32 is rotatably connected to the mounting block 34; the adjuster 35 is connected to the slider 32 and is used to adjust the friction coefficient of the friction limiter 3, and is an adjustable screw or nut. The mounting block 34 is connected to the outer wall of the connecting frame 22, and the slide rail 33 is connected to the inner wall of the window frame 1, so that the support rod 31 can be located between the window frames 1 and 1, so that the slide rail 33 can drive the support rod 31 to be raised or retracted. The adjuster 35 allows the user to adjust the friction force of the slider 32 according to actual needs, so that the friction limiter 3 can adapt to window sashes 2 of different weights, thereby improving the practicality of the top-hung window system.
[0048] In one embodiment, the friction stopper 3 further includes: a resistance member; the resistance member is connected to the window frame 1 or the window sash 2 and is used to abut against the slider 32; the resistance member is a limit spring or a damper. The limit spring or damper is used to increase the friction force of the friction stopper 3, ensuring that the window sash 2 can stop smoothly when closing, and provide sufficient resistance when the window sash 2 is opened, so that after the slider 32 stops moving, the two ends of the support rod 31 are fixed, so that a certain angle is maintained between the window sash 2 and the window frame 1.
[0049] In one embodiment, there are two friction stoppers 3, which are mirror-imaged on the two side walls of the window frame 1, and the slide rail 33 is arranged along the vertical direction of the window frame 1. The slide rail 33 is installed on the side frame 14, and the end of the support rod 31 away from the slider 32 is connected to the vertical profile 223. When the wind pressure does not exceed the friction coefficient of the friction stopper 3, the two friction stoppers 3 can stably support the window sash 2 in the open state, making the top-hung window system structure more stable and reliable.
[0050] In this embodiment, the window frame 1 is provided with a hooking groove 16, and the top of the window sash 2 is provided with a hooking portion 24 corresponding to the hooking groove 16, and the hooking portion 24 is hooked to the hooking groove 16; the notch edge of the hooking groove 16 close to the window sash 2 is in the shape of a circular shaft, and the hooking portion 24 is arranged in an arc shape. The hooking portion 24 rotates along the notch of the circular shaft-shaped hooking groove 16, so that the window sash 2 can flexibly rotate relative to the window frame 1 to form a certain angle with the window frame 1, and is located between the window sash 2 and the window frame 1, preventing rainwater erosion, ensuring the durability of the hooking groove 16 and the hooking portion 24, and further ensuring the stability of the connection between the window sash 2 and the window frame 1. In other embodiments, the window sash 2 is rotatably connected to the window frame 1 through a rotating shaft or a hinge seat.
[0051] In one embodiment, the edges of the window frame 1 and the edges of the window sash 2 are both provided with sealing strips 5. Specifically, the side walls where the window sash 2 and the window frame 1 are attached to each other are provided with sealing strips 5. The sealing strips 5 can prevent rainwater from entering the room through the gap between the window frame 1 and the window sash 2, and at the same time, when the window sash 2 is automatically closed and quickly attached to the window frame 1 under strong wind pressure, it has a certain buffering effect, avoiding excessive collision between the window sash 2 and the window frame 1 to damage the window sash 2 or the window frame 1, and ensuring the safety and structural stability of the top-hung window system.
[0052] In one embodiment, it further includes: a handle 6, a transmission device and a transmission assembly 7; the handle 6 is rotatably connected to the bottom of the window sash 2; the transmission device is transmission-connected to the handle 6; the transmission assembly 7 is connected to the transmission device; the transmission assembly 7 includes: a connecting rod 71; the connecting rod 71 is provided with a locking column 72, and the window frame 1 is provided with a locking block 8 corresponding to the locking column 72. Specifically, the handle 6 is connected to the inner side wall of the lower profile 222, that is, the side of the lower profile 222 close to the handle portion 442, the transmission device and the connecting rod 71 are both arranged in the connecting frame 22, and the transmission device is used to convert the rotational motion of the handle 6 into a linear motion, driving the connecting rod 71 to move, so that the locking column 72 is away from or close to the locking block 8, so as to separate or lock the window sash 2 and the window frame 1. In actual application, when the user needs to close the window, the user pulls the window sash 2 toward the window frame 1 until the window sash 2 is in contact with the window frame 1, and then rotates the handle 6 to lock the window sash 2; after the window sash 2 is automatically closed under strong wind pressure and locked by the elastic member 4, the user can choose to lock the window sash 2 again through the handle 6 to achieve double protection of the locking of the window sash 2, so that the window sash 2 is closely fitted with the window frame 1, and the resistance of the window sash 2 to positive and negative pressures is enhanced.
[0053] In one embodiment, there are two transmission assemblies 7, and the two transmission assemblies 7 are mirror-imaged at the edge of the window sash 2 with the central axis of the window sash 2 as the mirror axis. The two transmission assemblies 7 balance the restricting force on the window sash 2, so that the window sash 2 can be firmly locked, thereby ensuring the structural stability of the top-hung window system.
[0054] In one embodiment, there are two connecting rods 71, one connecting rod 71 is horizontally arranged at the bottom of the window sash 2, and the other connecting rod 71 is vertically arranged at the side wall of the window sash 2, and the adjacent connecting rods 71 are connected by a corner turner 73; there are two transmission assemblies 7, and the two transmission assemblies 7 are mirror-connected on both sides of the transmission. Specifically, one connecting rod 71 is horizontally arranged relative to the lower profile 222 and is located inside the lower profile 222; the other connecting rod 71 is vertically arranged relative to the vertical profile 223 and is located inside the vertical profile 223; the corner turner 73 is located at the connection between the vertical profile 223 and the lower profile 222, and is located between the vertical profile 223 and the lower profile 222. The transmission and the corner turner 73 are prior art, and the specific structures of the transmission and the corner turner 73 are not described in detail here. The handle 6 rotates, the transmission drives the connecting rod 71 in the lower profile 222 to move, the connecting rod 71 in the lower profile 222 drives the angler 73 to move, and the angler 73 drives the connecting rod 71 in the vertical profile 223 to move, so that the locking columns 72 on the two connecting rods 71 are close to or away from the locking block 8.
[0055] The present embodiment is a top-hung window system that self-closes under strong wind pressure. By installing a friction limiter and an elastic part on the window sash, the slider can slide relative to the slide rail when the wind pressure exceeds the friction coefficient of the friction limiter, thereby reducing the angle between the support rod and the window frame. The window sash approaches the window frame under the action of its own weight. When the elastic part at the edge of the window sash contacts the window frame, it moves away from the window frame under the action of its own elasticity until the window sash fits the window frame. The elastic part rebounds into the lock seat, realizing automatic closing and locking of the window sash, avoiding rainwater from entering the room, and enabling the top-hung window system to prevent damage to indoor property due to wind and rain.
