Abstract
Description
Technical Field
[0001] This invention belongs to the field of door and window technology, and relates to a pull-out window. Background Technology
[0002] With the rapid development of my country's economy, various buildings have sprung up, and the forms of doors and windows have also become more diverse. Under the national policy of advocating energy conservation and thrift, and against the backdrop of the diversification and modernization of building doors and windows, China's door and window industry has gradually realized the advanced nature of lift-up window systems. As a result, more and more buildings are now choosing and using lift-up windows, and the market demand is huge, with broad development prospects.
[0003] Currently, the aluminum-clad wood sliding window with announcement number CN201474519U on the market includes a wooden window frame fixed to the wall, an inner wooden window sash that can slide up and down along the window frame, and an outer wooden window sash. Both the inner and outer window sashes are fitted with insulated glass. Spring balancing mechanisms are respectively installed between the inner and outer window sashes and the window frame to lock the inner and outer window sashes. An aluminum alloy outer frame, acting as a baffle, is fixed to the outside of the window frame to prevent the outer window sash from falling outwards. The outer sides of the inner and outer window sashes are covered with aluminum alloy sheets. This utility model proposes an aluminum-clad wood sliding window that is not easily corroded on the outside and is practical, safe, and reliable.
[0004] However, some problems exist: 1. The window sash of this mechanism lacks a deceleration device when it falls, making it prone to rapid descent due to gravity, potentially causing the operator's hand to be pinched. 2. Debris easily accumulates on the lower frame of the mechanism when the window is opened. 3. Water easily accumulates on the lower frame of the mechanism, causing it to rust. Summary of the Invention
[0005] This solution provides a pull-up window to address the problem that the window may pinch the operator's hand when it falls.
[0006] This solution provides a pull-out window, including a window, a frame, and a locking unit. The frame includes an interconnected upper frame, lower frame, left frame, and right frame. The window includes a first window and a second window, both of which are slidably connected to the left frame and the right frame. The first window and the second window cooperate with each other. The locking unit includes a first locking member and a second locking member, the first locking member cooperating with the first window and the second locking member cooperating with the second window. It also includes a buffer unit, which includes a first cylinder, an airbag, and a pressing block. The first cylinder includes a first cylinder body, a first piston, and a first push rod. The first cylinder body is fixedly connected to the lower frame and has a vent hole. The first piston is slidably connected to the first cylinder body. One end of the first push rod is fixedly connected to the first piston and the other end cooperates with the pressing block. The pressing block is fixedly connected to the first window, and the vent hole communicates with the airbag.
[0007] The principle behind this solution is as follows: When the operator needs to open the window, they only need to open the first and second locking mechanisms. The operator can then simply pull the first and second windows, allowing them to slide along the frame. When the operator needs to close the window, they only need to lower the first window, which will be locked by the first locking mechanism, and the second window only needs to be raised to contact the second locking mechanism to lock.
[0008] When closing the first window, gravity could cause it to fall too quickly, potentially injuring the operator's hand. This device uses a buffer unit to slow the descent of the first window. Specifically, as the first window falls, its pressing block strikes the first push rod, causing it to move downwards and expel gas from the first cylinder through the vent into the airbag. Under pressure, the first window slowly descends until it closes. When the first window opens, the airbag forces the gas back into the first cylinder, returning the first push rod to its original position.
[0009] The beneficial effect of this solution is that the device effectively reduces the falling speed of the first window through the buffer unit, so that the operator's hand will not be pinched.
[0010] Furthermore, it also includes a base plate, which comprises a left base plate and a right base plate. The lower frame includes a left groove and a right groove. The left groove is fixedly connected to the left base plate, and the right groove is fixedly connected to the right base plate. The first cylinder is located inside the left base plate, and the left groove and right groove cooperate with each other. The base plate allows for better placement of the first lever and ensures that the first cylinder does not affect the sliding of the first window.
[0011] Furthermore, the airbag is replaced by an anti-slag unit, the left bottom plate and the right bottom plate are slidably connected, the anti-slag unit includes a second cylinder and a conduit, the second cylinder is connected to the vent of the first cylinder through the conduit, the second cylinder is located inside the left bottom plate, the second cylinder includes a second cylinder body, a second piston and a second push rod, the second piston is slidably connected to the second cylinder body, one end of the second push rod is fixedly connected to the second piston, and the other end is engaged with the right bottom plate, the left groove and the right groove are magnets.
[0012] When the first window is opened, the left and right slots attract each other under the action of magnetism and close together, which can effectively prevent garbage and water from accumulating inside the lower frame when the window is opened. This causes the second push rod of the second cylinder to be squeezed, which in turn causes the gas in the second cylinder to be squeezed into the first cylinder through the conduit, causing the first push rod of the first cylinder to extend.
[0013] When the first window is closed, it slides downwards, and the pressing block strikes the first push rod of the first cylinder. The first push rod drives the first piston downwards, compressing the gas in the first cylinder and transferring it through the conduit to the second cylinder. The second push rod in the second cylinder pushes the left and right slots apart, allowing the first window to fall inside the lower frame. This achieves the effect of the lower frame closing when the window is open and opening when the window is closed, preventing debris from clogging the lower frame and preventing the first window from being stored there.
[0014] Furthermore, two slag-prevention units and two buffer units are provided, located on the left and right bottom plates respectively, and the two slag-prevention units cooperate with each other. Two second cylinders are provided, and the two second push rods of the second cylinders are on the same horizontal line, so that when they extend, they can mutually abut and support the left and right tanks. Providing two slag-prevention units and two buffer units increases the buffering effect and prevents the first window from tilting.
[0015] Furthermore, the first window includes a first glass pane and a first window frame, and the second window includes a second glass pane and a second window frame. Anti-collision devices are provided at both ends of the first window frame, and these devices are located at the junction of the first and second windows. The window frame serves to protect the glass pane, and the anti-collision devices act as a buffer when the first window frame impacts the left side frame and the second window frame during sliding, preventing damage to the first window frame.
[0016] Furthermore, handles are provided on the first and second window frames. The handles make it easier for the operator to open the first and second windows.
[0017] Furthermore, the base plate is provided with a drain outlet. The drain outlet can drain water accumulated on the lower frame to the outside, preventing water accumulation on the lower frame from causing the device to rust.
[0018] Furthermore, the first window frame and the first glass are fixedly connected by adhesive, and the second window frame and the second glass are fixedly connected by adhesive. The adhesive makes the first glass, the second glass, and the first and second window frames more tightly fixed, and also facilitates replacement when needed. Attached Figure Description

[0021] As attached Figure 1 , Figure 2 , Figure 3 As shown: Example 1: This solution provides a pull-out window, including a window, a frame, and a locking unit. The frame includes an interconnected upper frame 3, lower frame 6, left frame 7, and right frame 4. The window includes a first window and a second window, both of which are slidably connected to the left frame 7 and right frame 4. The first and second windows are arranged one behind the other, and the right frame of the first window and the left frame of the second window contact each other when the window is in the closed state to prevent wind from seeping in through gaps, thus enhancing the window's airtightness. The locking unit includes a first locking element 13 and a second locking element 8. When the first window is at its lowest position, it contacts the first locking element 13, which locks the first window. To open, the first locking element 13 needs to be pressed. When the second window is raised to its highest position, it contacts the second locking element 8, which locks the second window. To open, the second locking element 8 needs to be pressed.
[0022] It also includes a buffer unit, which includes a first cylinder 14, an airbag 26, and a pressing block 10. The first cylinder 14 includes a first cylinder body, a first piston 15, and a first push rod 16. The first cylinder body is fixedly connected to the lower frame 6 and has a vent hole. The first piston 15 is slidably connected to the first cylinder body. One end of the first push rod 16 is fixedly connected to the first piston 15 and the other end is aligned with the pressing block 10. When the pressing block 10 falls with the first window, it will touch the first push rod 16. The pressing block 10 is fixedly connected to the first window, and the vent hole is connected to the airbag 26. It also includes a base plate 17, which comprises a left base plate 22 and a right base plate 23. The lower frame 6 includes a left groove 25 and a right groove 24. The left groove 25 is fixedly connected to the left base plate 22, and the right groove 24 is fixedly connected to the right base plate 17. The first cylinder 14 is located inside the left base plate 22. The gap between the left groove 25 and the right groove 24 allows the first window to fall in. The left base plate 22 and the right base plate 23 are slidably connected. There are two buffer units, located on the left and right sides of the base plate 17.
[0023] The first window frame includes a first upper window frame 5, a first left window frame, a first lower window frame 9, and a first right window frame that are fixedly connected in sequence. The second window frame includes a second upper window frame 11, a second left window frame, a second lower window frame 12, and a second right window frame that are fixedly connected in sequence. The first left window frame and the first right window frame are slidably connected to the left side frame 7 and the right side frame 4. The second left window frame and the second right window frame are slidably connected to the left side frame 7 and the right side frame 4.
[0024] When the operator needs to open the window, they only need to open the first locking element 13 and the second locking element 8. The operator can then pull the first window and the second window, which will slide along the frame. When the operator needs to close the window, they only need to lower the first window, which will be locked by the first locking element 13, and the second window only needs to be raised to contact the second locking element 8 to lock.
[0025] When the first window closes, gravity could cause it to fall too quickly, potentially pinching the operator's hand. This device uses a buffer unit to slow down the descent of the first window. Specifically, as the first window falls, the pressing block 10 strikes the first push rod 16, causing it to move downwards. This push rod 16 then releases gas from the first cylinder through the vent into the airbag 26. Under pressure, the first window descends slowly until it closes. When the first window opens, the airbag 26 forces the gas back into the first cylinder 14, returning the first push rod 16 to its original position. This device effectively reduces the descent speed of the first window through the buffer unit, preventing the operator from being pinched on the hand.
[0026] Example 2: Replace the airbag 26 with a slag-proof unit, and keep the rest unchanged.
[0027] The left bottom plate 22 and the right bottom plate 23 are slidably connected. The slag prevention unit includes a second cylinder 18 and a conduit 19. The second cylinder 18 is connected to the vent of the first cylinder 14 through the conduit 19. The second cylinder 18 is located inside the left bottom plate 22. The second cylinder 18 includes a second cylinder body, a second piston 20 and a second push rod 21. The second piston 20 is slidably connected to the second cylinder body. One end of the second push rod 21 is fixedly connected to the second piston 20, and the other end is aligned with the right bottom plate 17, so that the second push rod 21 can effectively push the right bottom plate 17. The left tank 25 and the right tank 24 are magnets.
[0028] When the first window is opened, the left groove 25 and the right groove 24 attract each other under the action of magnetic force and close together, which can effectively prevent garbage and water from accumulating in the lower frame 6 when the window is opened, so that the second push rod 21 of the second cylinder is squeezed, and the gas in the second cylinder is squeezed into the first cylinder through the conduit 19, causing the first push rod 16 of the first cylinder to extend.
[0029] When the first window is closed, it slides downwards, and the pressing block 10 strikes the first push rod 16 of the first cylinder. The first push rod 16 drives the first piston 15 to move downwards, compressing the gas in the first cylinder from the conduit 19 into the second cylinder 18. The second push rod 21 in the second cylinder pushes the left groove 25 and the right groove 24 apart, allowing the first window to fall into the lower frame 6. This achieves the effect of the lower frame 6 closing when the window is open and opening when the window is closed, preventing debris from clogging the lower frame 6 and preventing the lower frame 6 from storing the first window.
[0030] Two slag-prevention units and two buffer units are provided, located on the left bottom plate 22 and the right bottom plate 23 respectively, and the two slag-prevention units cooperate with each other. Two second cylinders are provided, and the two second push rods 21 of the second cylinders are on the same horizontal line, so that when they extend, they can mutually abut and open the left tank 25 and the right tank 24. Providing two slag-prevention units and two buffer units increases the buffering effect and prevents the first window from tilting.
[0031] The first window includes a first glass pane 1 and a first window frame, and the second window includes a second glass pane 2 and a second window frame. Anti-collision devices are provided at both ends of the first window frame, and these devices are located at the junction of the first and second windows. The window frame serves to protect the glass, and the anti-collision devices act as a buffer when the first window frame impacts the left side frame 7 and the second window frame during sliding, preventing damage to the first window frame.
[0032] Handles are provided on the first and second window frames. The handles make it easier for the operator to open the first and second windows.
[0033] The base plate 17 is equipped with a drain outlet. The drain outlet can drain the water accumulated on the lower frame 6 to the outside, preventing the device from rusting due to water accumulation on the lower frame 6.
[0034] The first window frame and the first glass pane 1 are fixedly connected using adhesive, and the second window frame and the second glass pane 2 are fixedly connected using adhesive. The adhesive makes the first glass pane 1 and the second glass pane 2 more tightly fixed to the first and second window frames, and also facilitates replacement when needed.
