Description

Technical Field

[0001] The present invention relates to the technical field of building doors and windows, and more specifically, to a lifting sliding window. Background Art

[0002] With the higher requirements for the functions, energy conservation, and safety performance indicators of building doors and windows. Building products achieve the goals of low-carbon energy conservation and emission reduction and realize ultra-low energy consumption.

[0003] At present, in order to achieve the above goals, external building window products basically adopt the structure of casement windows combined with insulating glass technology to meet the above requirements; however, when the opening sash is ventilated and opened, the inward opening occupies indoor space and is prone to injury, and the outward opening sash is prone to falling accidents when opened in strong wind weather. At the same time, it consumes more aluminum alloy materials, and the energy production cost is high. The section of the casement window profile is large, significantly reducing the indoor lighting area. The ratios of the window frame to the glass are 30% and 70% respectively.

[0004] Around 2005, there were a large number of sliding windows and American lifting windows on the market at the same time. The characteristics of these two window types are that the opening does not occupy indoor space, the profile section is relatively small, the glass value is large, the indoor lighting rate is high, the opening and closing are convenient, and the processing is simple. Since the opening sash uses pulleys to move relatively floatingly on different inner and outer sliding tracks to complete the opening and locking of the window sash, there is an energy leakage phenomenon caused by the gap between the opposite two sashes, and the airtightness, watertightness, wind pressure resistance, and performance are poor. Due to the need for internal and external drainage at the section of the profile frame and sash, relative sealing treatment cannot be adopted. The sash pulley adopts a ball structure, the sash self-weight is relatively large, the opening torque and noise are large, and the reason for the loss is that the profile design is unreasonable. The design dimensions of the lifting and sliding sash profile sections are relatively small, with a maximum of no more than 42 mm. Coupled with the width of the fixed pressing strip, high-performance insulating glass cannot be installed. The gaps between various parts of the frame and sash are filled with siliconized wool strips with extremely low sealing performance, and it is impossible to meet the national standard requirements of GB / T8478-2020 for the airtightness, watertightness, wind pressure resistance, energy conservation, heat insulation, and sound insulation performance of the window; a series of problems related to sealing and energy conservation are not fully considered. In addition to the above problems, the lifting window also needs to move up and down due to different opening methods. In order to save the lifting force, a method combining a spring spiral torsion bar and manual lifting is adopted to realize the lifting and closing of the window sash. The design of this lifting assist mechanism is simple, the frictional resistance of the spiral movement of the spring steel sheet is large, and if the weight of the window sash is too large, it will cause difficulty in opening. At the same time, the spring spiral torsion bar has poor stability and reliability and is often damaged, affecting normal use. Therefore, due to the unqualified airtightness, watertightness, wind pressure resistance, heat preservation, energy conservation, and stability indicators of the above two types of windows, these two types of practical windows cannot be applied to people's daily lives.

[0027] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments.

[0028] Embodiment 1:

[0029] Please refer to Figures 1-3, A lift and push-pull window, including a window frame. A driving component 13 is arranged on the window frame. The window frame profile structure adopts an assembled structure combining aluminum alloy profiles with heat insulation and heat preservation. Nylon 66 polycarbonate material is used as the heat preservation medium to form a heat-insulating and energy-saving aluminum alloy profile structure framework by connecting the front and rear aluminum alloy profiles in series, meeting the requirements of heat preservation, low carbon, energy conservation, and green environmental protection. The window frame includes a fixed frame A1 and a fixed frame B2 arranged opposite to each other. Two fixed frame corner code cavities 3 are respectively arranged on the inner sides of the fixed frame A1 and the fixed frame B2. A window sash component is arranged between the two relatively arranged fixed frame corner code cavities 3. The driving component 13 is used to drive the window sash component to move; the movable push rod in the driving component 13 is connected to the movable end of the hidden sliding guide rail 7 installed on the lower side or both sides of the window sash component. When the push rod contracts and extends, it pulls the window sash component to move left and right or up and down, realizing the push-pull or up and down lift opening and closing functions of the window sash.

[0030] The window sash component includes two relatively arranged fixing parts 4. A connecting part A5 is arranged on one side of the fixing part 4 close to the fixed frame corner code cavity 3. Sliding guide rails 7 are arranged on both sides of the connecting part A5. A transmission connecting part 8 is arranged outside the two sliding guide rails 7. Protrusions A801 are arranged at both ends of the transmission connecting part 8. Protrusions B501 are arranged opposite to each other on both sides of the connecting part A5. An arc-shaped groove is arranged inside the protrusion A801. The protrusion B501 is an arc structure with an inward concave on the outside. The sliding guide rail 7 is located between the protrusion A801 and the protrusion B501, used to limit the position of the fixing part 4, so that the window sash component slides along the sliding guide rail 7. The sash and the frame are rigidly connected through the sliding guide rail 7 to achieve the purpose of fixing the window sash, preventing the window sash from falling off the guide rail and causing high-altitude falling accidents, and ensuring the safe use of the doors and windows.

[0031] In this application, a sealing rubber strip 9 is arranged between the fixed frame A1, the fixed frame B2 and the fixing part 4. The sealing rubber strip 9 matches the installation groove of the window frame and can meet the sealing requirements of different performance requirements. A push-pull sash cover plate 10 is arranged on the side of the fixing part 4 close to the outdoor side for fixing the insulating glass.

[0032] In this application, a push-pull sash corner code cavity 401 is arranged on the fixing part 4, and the connecting end of the connecting part A5 is located in the push-pull sash corner code cavity 401.

[0033] In this application, a window sash 11 is arranged between the two relatively arranged fixing parts 4. A sealant 12 is arranged between the window sash 11 and the fixing part 4. Among them, the window sash 11 includes insulating glass, and the sealant 12 includes silicone structural sealant.

[0034] In this application, the window sash 11 is divided into an outer fixed sash and an inner movable sash. The fixed frame A1 and the fixed frame B2 are arranged vertically. A driving component 13 is arranged in one group of relatively arranged fixed frame corner code cavities 3. A connecting part B6 is connected to the output shaft of the driving component 13, and the other end of the connecting part B6 is connected to the connecting part A5.

[0035] Among them, both ends of the fixed frame A1 and the fixed frame B2 are respectively connected by the upper frame 15 and the lower frame 16. The upper surface of the lower frame 16 on the outdoor side is inclined downward. One end of the fixing member 4 close to the fixing frame corner code cavity 3 on the upper frame 15 and the lower frame 16 is provided with a sealing rubber member 14. When the window sash is in the downward closed state, for the lapping fit gap caused by the lapping part of the outer fixed sash and the inner movable sash, the upper and lower two special highly elastic sealing rubber members 14 are installed on the end faces of the inner and outer sashes to block the gap, ensuring the sealing performance of the whole window when the inner and outer sashes are closed.

[0036] When the inner movable sash is opened, the circuit is connected through the remote control switch. The electric push rod installed in the cavity of the lifting frame extends upward, and the window sash is pulled upward to open through the connecting member. When it reaches the required position, press the stop switch to cut off the power supply and stop lifting to complete the opening. The operation of closing the window is the opposite.

[0037] In terms of control, it can also be controlled by a smart phone. Through the Tuya Smart APP wirelessly connected to the Internet WLAN, remote intelligent control opening of the simultaneous lifting and sliding window can be realized.

[0038] In this application, the driving component 13 is one of a linear electric push rod or a balanced gas spring.

[0039] As Figure 7 shown, on both sides of the piston in the cylinder of the balanced gas spring, a pneumatic one-way valve 19 with opposite installation directions is installed respectively. The front and rear end cavities of the piston are filled with inert gas nitrogen with the same pressure to form pressure balance. The pneumatic one-way valves 19 installed on both sides of the piston are closed in the state of pressure balance on both sides. The piston is in an environment of pressure balance before and after, and remains stationary. When the piston rod is subjected to a certain external pulling force and the piston moves with the piston rod to generate displacement, the cavity volume changes, the gas is compressed and the pressure rises, and the pressure balance on both sides of the piston is damaged. At the same time, the one-way valve in the high-pressure cavity is pushed open by the high-pressure gas and flows to the low-pressure cavity at the rear of the piston. When the external force on the piston rod stops, the pressure balance in the front and rear cavities is restored, and the one-way valve closes the cavity under the action of the spring to prevent pressure relief, and the piston stops moving to maintain balance.

[0040] One end of the cylinder barrel of the balanced gas spring is fixed in the equipment installation cavity of the window frame profile. The piston rod is connected to the movable end of the hidden sliding guide rail 7 installed on the lower edge or both sides of the window sash through a movable joint. By the power of people to destroy the pressure balance of the balanced gas spring cylinder, the generated pressure difference is used to make the window sash contract and extend to pull the window sash to move left and right or up and down, realizing the functions of pushing, pulling, lifting and closing of the window sash. The piston rod of the balanced gas spring drives the connecting member B6, the connecting member A5 and the fixing member 4 connected to it to move along the sliding guide rail 7, thereby realizing the movement of the window sash assembly. This solution can achieve the purpose of easily controlling the lifting and sliding window without using electric energy, and at the same time is simple, practical, and has high stability and reliability.

[0041] Embodiment 2:

[0042] Please refer to Figures 4-7 , the difference from the basis of Embodiment 1 is that the fixed frames A1 and B2 are horizontally arranged, and drive components 13 are arranged in both fixed frame corner code cavities 3 of the fixed frame A1. A connecting piece B6 is connected to the output shaft of the drive component 13, and the other end of the connecting piece B6 is connected to the connecting piece A5.

[0043] The cross-section of the window frame profile of the present invention adopts a design without a sliding rail, and the four-sided frame has a unified structure without distinction of up, down, left, or right; a fixed frame corner code cavity 3 is designed, and the frame assembly mode is completed by corner assembly. The window frame has increased mechanical strength compared to the original screw assembly, and the cavity can conveniently accommodate the installation of electric push rods and balanced gas spring power components for pushing and pulling. The upper and lower inner notches of the frame profile are respectively provided with two inner and outer linear sliding rails 7. The window sash moves left and right along the sliding rail to complete the opening and closing of the window sash. A sealing rubber strip 9 is provided on the inner side of the fixed frame. After the inner and outer sashes are closed, a space gap is generated at the overlapping joint of the two sashes. Two high-elastic special rubber seals are used for sealing treatment to prevent affecting the overall sealing performance and airtightness of the sliding window and ensure the overall performance of the sliding window.

[0044] In this application, since the fixed sliding rail on the upper part of the frame profile and the frame-sash floating structure for the movement of the sash pulley are removed, and the sash is rigidly connected to the frame through the sliding rail 7, the purpose of fixing the window sash is achieved, and the risk of the window sash falling off the rail and causing a high-altitude falling accident is restricted, ensuring the safe use of the doors and windows.

[0045] When the sliding sash is opened, the circuit is connected through a remote control switch. According to the switch sequence, the electric push rods installed in the upper cavity of the sliding frame extend outwards left and right, and the window sash is pulled left and right through the connecting members to complete the opening action and reach the required position. Press the stop switch to cut off the power supply and stop the pushing and pulling action to complete the window opening. The closing operation is the opposite.

[0046] Among them, the opening and closing of the sliding window can also be changed to pneumatic drive, and the electrical components are replaced with a balanced energy storage cylinder with a working stroke of 600 mm, also known as a balanced gas spring. The gas spring consists of a cylinder barrel, a piston rod, a piston, and a movable joint.

[0047] On the basis of maintaining the original outer dimensions of the frame profile cross-section, the original fixed track of the frame and sash profiles and the sash floating assembly structure design are removed, and the three original fixed tracks on the window frame profile are removed, increasing the inner cross-sectional dimension of the frame profile by more than 20 MM, increasing the external width dimension of the sash cross-section by 10 MM, the depth of the insulating glass installation notch reaching 20 MM, and the thickness reaching 36 MM, meeting the thickness requirements of high-performance insulating glass.

[0048] The original W-shaped structure of the frame profile and the h-shaped structure of the sash profile are changed to a U-shaped structure of the frame profile and a d-shaped structure of the sash profile. A hidden linear sliding guide 7 is installed between the sash and the frame to achieve a rigid connection between the frame and the sash, enabling the planar combination of two frame and sash profiles with different cross-sections to form an integral whole, and allowing for left and right sliding. This eliminates the problems of seal leakage and heat loss caused by excessive assembly gaps in the traditional floating sash. At the same time, with the d-shaped structure design of the sash profile, the fixed pressing strip for insulating glass is cancelled and changed to a curtain wall fixing form, combined with glue injection fixing and a cover plate, reducing heat conduction between hot and cold, and improving the heat insulation performance of the sash and the entire window. The traditional and backward method of sealing with siliconized wool strips is changed to using rubber sealing materials as the sealing means, which can improve the sealing performance of lifting and sliding windows. The U-shaped frame profile and the d-shaped sash profile are made into the frame and sash, and the sliding fit gaps between the sash and the frame up and down, and the overlapping gaps between the inner sliding sash and the outer sliding sash are designed. Through the inner groove of the frame profile and the notch at the convex part on the outer surface of the sash profile, a glued rubber sealing strip and a double-channel rubber material that can be inlaid are used for sealing treatment at the four sides between the frame and the sash and at the overlapping parts of the inner and outer sashes when they are closed.

[0049] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and the descriptions in the specification are only preferred examples of the present invention and are not used to limit the present invention.
