Description

Technical Field

[0001] This utility model relates to the field of aluminum alloy doors and windows, specifically to a novel lift window that can be operated manually and electrically. Background Technology

[0002] A lift window (also known as a "sliding lift window" or "lift window") is a window design that combines the features of sliding windows and casement windows. It is commonly found in modern buildings. Its main feature is that the window sash can be pushed and pulled vertically upwards, while also having good sealing and ventilation effects.

[0003] Current lift windows primarily use a screw or lifting belt to move the window up and down, thus opening and closing the window. The screw drives the window to close by rotating, while the lifting belt lifts the window to close. One end of the lifting belt is fixed to a pivot, and the other end is installed at the top of the window. The rotation of the pivot causes the lifting belt to raise the window. All of the above lifting methods are electrically operated. However, a purely electric mode will encounter difficulties in use during power outages or other emergencies, while a purely manual mode cannot meet the modern pursuit of efficiency and convenience. Furthermore, the drive mechanism of the above lift windows cannot be used for manual operation after a power outage. Utility Model Content

[0004] To address the shortcomings of the aforementioned technologies, this utility model proposes a novel lifting window that facilitates both electric and manual operation. This allows the window to be raised and lowered even during power outages, while also enabling the window to be locked and its opening size adjusted.

[0005] To achieve the above objectives, the present invention provides a novel lift window, comprising a window frame, a mullion, a fixed window, a lift window, and a lifting mechanism. A mullion is installed on the window frame, and a fixed window is installed on the window frame below the mullion. A vertical slide groove is provided on the window frame, and a lift window is inserted into the slide groove. The lift window moves up and down within the slide groove, and a lifting mechanism is provided between the lift window and the window frame.

[0006] A locking component is installed on the lifting mechanism to lock the lifting mechanism and prevent the window from descending rapidly.

[0007] The lifting mechanism includes an electric power component and a manual lifting component. The electric power component includes gears and racks. Gears are installed inside both sides of the window frame. Vertical grooves are opened on the side of the lifting window, and racks are installed in the grooves. The racks mesh with the gears. A mounting slot is opened at the top of the mullion, and a rotating shaft is installed in the mounting slot at the top of the mullion. The rotating shaft is connected to two gears. The electric power component is installed in the mounting slot at the top of the mullion. The electric power component and the rotating shaft are driven by a gearbox. A cover is placed on the top of the mounting slot. The manual lifting component is a rocker arm, which is driven by the rotating shaft. This enables both manual and electric lifting.

[0008] Preferably, the locking assembly includes a retaining ring, a ratchet, and a pawl. A retaining ring coaxial with a rotating shaft is mounted on the center chuck. The rotating shaft is equipped with a ratchet, and the retaining ring is equipped with a pawl. The output shaft of the electric power assembly extends out of the gearbox and is fitted with a one-way rotating sleeve. A one-way bearing seat is provided between the one-way rotating sleeve, the output shaft, and the center chuck. A movable sleeve that slides on the outer wall of a guide bearing is fitted on the wall of the one-way rotating sleeve. A swing arm is hinged to the outer wall of the one-way rotating sleeve. A connecting rod is hinged between the swing arm and the movable sleeve. A tension spring is installed on the outer wall of the one-way bearing, which enables the swing arm to fit against the outer wall of the one-way rotating sleeve. A push plate is installed at the end of the moving sleeve, which rotates with the moving sleeve. A pressing rod is installed on the fixed ring and slides with the fixed ring. A return spring is set between the pressing rod and the fixed ring. A rotating sleeve is installed on the pressing rod, and a pawl is fixed on the rotating sleeve. A spiral groove is opened on the rotating sleeve. A sliding rod embedded in the spiral groove is fixed on the pressing rod, and the push plate presses on the pressing rod.

[0009] Preferably, a rotating shaft is mounted on the window frame via bearings. A second bevel gear meshes with the rotating shaft. The rotating shaft extends out of the window frame, and an insertion groove is provided at one end of the rotating shaft extending out of the frame. A rocker arm is inserted into the insertion groove, and an elastic telescopic block is provided within the insertion groove. When the rocker arm is inserted into the insertion groove, the elastic telescopic block is pressed and moved inward. A drive shaft is mounted on the outer periphery of the gearbox via bearings. First drive wheels are mounted at both ends of the drive shaft. A movable second drive wheel is mounted on the drive shaft inside each first drive wheel. A shift fork is provided inside each second drive wheel. A compression spring is provided between the first and second drive wheels. A slant is mounted on each shift fork. The mounting slots of the face block, shift fork, and center muzzle are slidably engaged. Linkage plates are installed on the two inclined blocks, and these plates slidably engage with the mounting slots. A pull rope is installed on the linkage plate, and a pulley is installed in the mounting slot of the center muzzle. The other end of the pull rope is wound around the pulley and connected to a moving ring. A bearing is installed inside the moving ring. A waist-shaped hole is opened on the rotating shaft, and a pressing elastic telescopic block passes through the waist-shaped hole and is fixed to the inner wall of the bearing inside the moving ring. The rotating shaft is broken to form a first shaft, a second shaft, and a third shaft. The second shaft drives the gearbox. Drive wheels are installed at both ends of the second shaft. Drive wheels are also installed at the ends of the first and third shafts near the second shaft. Multiple drive wheels mesh with the first transmission wheel, and the second transmission wheel meshes with the drive wheels via the movement of the shift fork.

[0011] Preferably, a worm gear mechanism is installed inside the gearbox. The worm is coaxial with the output shaft and is fixed to the output shaft by welding. A turbine is installed below the worm by bearings. A first bevel gear, coaxial with the turbine, is installed on the front side of the worm gear by welding. A first bevel gear is also installed on the second shaft by welding. The two first bevel gears mesh, thus realizing the power transmission from the output shaft 55 to the second shaft.

[0012] Compared with the prior art, the advantages of this utility model are:

[0013] The window can be raised and lowered using both electric and manual methods, allowing for manual raising of the window in case of power failure or malfunction of the electric system.

[0014] A locking component is installed on the pivot to prevent the window from descending rapidly. At the same time, the locking component can lock the pivot, thus enabling different opening degrees of the window without the need for a gearbox self-locking mechanism to fix the window.

[0015] When operating manually, the electric system is separated from the shaft to avoid damaging the electric system. Attached Figure Description

[0033] The present invention will now be further described with reference to the accompanying drawings.

[0034] like Figure 1-16 As shown, a novel lift window 4 includes a window frame 1, a mullion 2, a fixed window 3, a lift window 4, and a lifting mechanism 5. The frame is a rectangular frame. A horizontal mullion 2 is installed in the middle of the window frame 1 by bolts. A fixed window 3 is installed in the window frame 1 below the mullion 2 by bolts. A vertical slide groove 6 is provided on the outside of the window frame 1. The slide groove 6 is located on the inner walls of the left and right sides of the window frame 1. The lift window 4 is inserted into the slide groove 6. Rollers that fit against the inner walls of the slide groove 6 are installed on the left and right sides of the lift window 4, so that the lift window 4 can be raised and lowered in the slide groove 6. A lifting mechanism 5 is provided between the lift window 4 and the window frame 1. The lifting mechanism 5 is used to operate the raising and lowering of the lift window.

[0035] The lifting mechanism 5 includes an electric power component 7 and a manual lifting component 14. The electric power component 7 includes a gear 8 and a rack 9. Gears 8 are mounted on the left and right sides of the window frame 1 via bearings. A vertical groove 10 is formed on the inner side of the lift window 4 facing the fixed window 3. A vertical rack 9 is mounted in the groove 10 via bolts. The rack 9 meshes with the gear 8. The rotation of the gear 8 drives the rack 9 to rise and fall. A mounting groove 56 is formed on the top of the mullion 2. A rotating shaft 11 is mounted in the mounting groove 56 on the top of the mullion 2 via bearings. Both ends of the rotating shaft 11 are inserted into the through holes in the center of the gear 8, and the rotating shaft 11 is fixed to the gear 8 via a flat key. In this way, the rotating shaft 11 drives the gear 8 to rotate. An electric power component is installed in the mounting groove 56 on the top of the mullion 2. The components include an electric power component, which is a stepper motor. The output shaft 55 and the rotating shaft 11 of the electric power component both extend into the gearbox 50. The gearbox 50 completes the transmission between the rotating shaft 11 and the electric power component, thus driving the rotating shaft 11 to rotate. A cover 13 is placed in the mounting groove 56 of the center mullion 2 and fixed with bolts, so that the top of the center mullion 2 is flat. The manual lifting component 14 is a rocker arm 15. The rocker arm 15 is driven by the rotating shaft 11, thus realizing manual and electric lifting. When the power is off, the electric power component cannot work. The rotating shaft 11 is rotated by rocking the rocker arm 15, so the lifting window 4 is raised and lowered under the action of the rocker arm 15. In this way, the lifting window 4 can still be raised and lowered in the event of a power outage or motor failure.

[0036] A locking assembly 20 is provided on the rotating shaft 11 to lock the rotating shaft 11 and prevent the lifting window 4 from descending rapidly. If the motor loses power or is damaged during the lifting process of the lifting window 4, the lifting window 4 will descend rapidly. This will damage the glass on the lifting window 4 upon rigid impact. The locking assembly 20 locks the rotating shaft 11 when the motor stops working, which can effectively prevent the lifting window 4 from being damaged by rapid descent.

[0037] Locking assembly 20 includes a retaining ring 21, a ratchet 22, and a pawl 23. The retaining ring 21, coaxial with the rotating shaft 11, is installed in the mounting groove 56 of the center latch 2. The retaining ring 21 is bolted to the bottom of the mounting groove 56. When the bolts are tightened, the ratchet 22 is installed. The pawl 23 is rotatably connected to the retaining ring 21. A spring is welded between the pawl 23 and the retaining ring 21. The spring causes the pawl 23 to swing inward, engaging and limiting the ratchet 22. The output shaft 55 of the electric power assembly passes through the gearbox 5. A one-way rotating sleeve 3324 is installed on the output shaft 55. A one-way bearing seat 25 is provided between the one-way rotating sleeve 3324, the output shaft 55, and the center mullion 2. That is, a one-way bearing is embedded between the one-way rotating sleeve 3324 and the output shaft 55. A connecting seat is fixed in the mounting groove 56 of the center mullion 2 by bolts. The outer wall of the one-way rotating sleeve 3324 and the connecting seat are connected by a one-way bearing. When the output shaft 55 rotates clockwise, the rotating shaft 11 rotates counterclockwise, thus raising and lowering the window 4. When the output shaft 55 rotates counterclockwise... When the output shaft 55 rotates clockwise, the one-way rotating sleeve 3324 rotates synchronously with the output shaft 55. When the output shaft 55 rotates clockwise, the one-way rotating sleeve 3324 rotates relative to the output shaft 55. The one-way bearing between the one-way rotating sleeve 3324 and the mounting groove 56 restricts the one-way rotating sleeve 3324 to rotate counterclockwise. Thus, the one-way rotating sleeve 3324 can only rotate when the output shaft 55 rotates counterclockwise. A movable sleeve 26 is fitted on the wall of the one-way rotating sleeve 3324 and slides on the outer wall of the guide bearing. Multiple oscillating shafts are hinged to the outer wall of the one-way rotating sleeve 3324. The swing arm 27 and the movable sleeve 26 are hinged by a connecting rod 28. A tension spring 29 is installed on the swing arm 27 and the outer wall of the one-way bearing by welding. The tension spring 29 makes the swing arm 27 fit with the outer wall of the one-way rotating sleeve 3324. When the one-way rotating cylinder rotates, the swing arm 27 opens due to centrifugal force. The swing arm 27 pushes the movable sleeve 26 outward through the connecting rod 28. When the one-way rotating cylinder stops rotating, the swing arm 27 fits with the one-way rotating sleeve 3324 through the tension spring 29, so the movable sleeve 26 moves inward.A push plate 30 is mounted on the end of the movable sleeve 26 via a bearing. The movement of the movable sleeve 26 drives the movement of the push plate 30. The push plate 30 rotates with the movable sleeve 26. A through hole is opened on the fixed ring 21 for the insertion of the pressing rod 31. The pressing rod 31 slides in the through hole of the fixed ring 21. Limiting plates are fixed to both ends of the pressing rod 31 by welding. The limiting plates prevent the pressing rod from disengaging from the through hole on the fixed ring 21. A return spring 32 is provided between the pressing rod 31 and the fixed ring 21 (the return spring 32 is sleeved on the pressing rod 31, and both ends of the return spring 32 are fixed to the fixed ring 21 and the limiting plates by welding. The pressing rod 31 is a rectangular rod, and the through hole is a rectangular hole, thus limiting the rotation of the pressing rod 31). A rotating sleeve 33 is sleeved on the pressing rod 31. The rotating sleeve 33 is a circular sleeve (the inner wall of the rotating sleeve 33 contacts the four corners of the pressing rod 31, so as not to affect the rotation of the rotating sleeve 33). The rotating sleeve 33 rotates on the pressing rod 31. The pawl 23 is fixed to the rotating sleeve 33 by welding. The rotating sleeve 33 drives the rotation of the pawl 23. A spiral groove 34 is opened on the rotating sleeve 33. A sliding rod 35 embedded in the spiral groove 34 is fixed to the pressing rod 31 by welding. The push plate 30 presses on the pressing rod 31. A guide rod is fixed to the back of the push plate 30 by welding. A ring fitted on the guide rod is fixed in the mounting groove 56 by welding. The push plate moves left and right, the stepper motor rotates clockwise, and the rotating shaft 11 also rotates clockwise, so the lifting window 4 rises. When the stepper motor rotates counterclockwise, the one-way rotating sleeve 3324 also rotates counterclockwise, so the moving sleeve 26 pushes the fixing ring 21. The push plate 30 presses the pressing rod 31, the pawl 23 swings outward, so the rotating shaft 11 can rotate counterclockwise, so the lifting window 4 falls.

[0038] A longitudinally arranged rotating shaft 16 is mounted on the front surface of the window frame 1 near the right side via a bearing. A second bevel gear 17 meshes with the rotating shaft 11. The front end of the rotating shaft 16 extends out of the window frame 1. A rectangular insert groove 18 is formed at the end of the rotating shaft 16 extending out of the frame. A rocker arm 15 is inserted into the insert groove 18. The rocker arm 15 is a Z-shaped rod, and the end of the rocker arm 15 inserted into the insert groove 18 is a rectangular block that engages with the insert groove 18. When the rocker arm 15 is inserted into the insert groove 18, it drives the rotating shaft 16 to rotate. An elastic telescopic block 19 is provided within the insert groove 18 and is embedded in the insert groove 18. Springs are embedded between blocks 19, pushing the elastic telescopic blocks 19 outwards. When the rocker arm 15 is inserted into the embedded hole, it presses the elastic telescopic blocks 19 inwards. A drive shaft 36 parallel to the rotating shaft 11 is mounted on the outer periphery of the gearbox 50 via bearings. First drive wheels 37 are welded to both ends of the drive shaft 36. A movable second drive wheel 38 is mounted on the drive shaft 36 inside each first drive wheel 37. The rotating shaft 11 is a rectangular rod, and the second drive wheel 38 has a rectangular through hole for the drive shaft 36 to pass through, so that the second drive wheel 38 rotates synchronously with the drive shaft 36. A shift fork 39 is provided inside each second drive wheel 38. A sliding sleeve is fitted on the inner drive shaft, and a bearing is installed on the sliding sleeve. The shift fork 39 contacts the inner side of the bearing. The sliding sleeve is moved outward by the shift fork 39, so that the second drive wheel 38 moves closer to the first drive wheel 37. A compression spring 40 is fitted on the drive shaft 36 between the first drive wheel 37 and the second drive wheel 38. The pressure drop pushes the second drive wheel 38 away from the first drive wheel 37. A inclined block 41 is installed on each shift fork 39 by welding. The inner side of the inclined block 41 is inclined. The shift fork 39 slides in the mounting groove 56 of the center muzzle 2 (a ring is installed on the inner wall of the mounting groove 56 by welding. A round rod that slides left and right in the ring is inserted into the ring. The round rod is fixed to the shift fork 39 by welding). A linkage plate 42 is engaged between two inclined blocks 41. The linkage plate 42 slides in conjunction with the mounting groove 56 (a longitudinally arranged rod is fixed in the mounting groove 56 by welding, the rod passes through the linkage plate 42 and the linkage plate 42 slides on the rod). A pull rope 43 is tied to the linkage plate 42. A pulley is installed in the inner wall of the mounting groove 56 of the middle muzzle 2 by bearing. The other end of the pull rope 43 is wrapped around the pulley and tied to a moving ring 44. The moving ring 44 is fitted on the rotating shaft 16. A bearing is engaged inside the moving ring 44 and fitted on the rotating shaft 16. An oblong hole 45 is opened on the rotating shaft 16. The pressing elastic telescopic block 19 passes through the oblong hole 45 and is fixed to the inner wall of the bearing inside the moving ring 44 by welding.The rotating shaft 11 is broken to form a first shaft 46, a second shaft 47, and a third shaft 48. The second shaft 47 is inserted into the gearbox 50 for transmission. Drive wheels 49 are fixed to both ends of the second shaft 47 by welding. Drive wheels 49 are also fixed to the ends of the first shaft 46 and the third shaft 48 near the second shaft 47 by welding. Multiple drive wheels 49 mesh with the first transmission wheel 37. The second transmission wheel 38 moves via a shift fork 39 to mesh with the drive wheels 49. During operation, when the lifting window 4 needs to be manually raised, the rocker arm 15 is inserted into the recess 18, pressing the elastic telescopic block 19 inward. This causes the elastic telescopic block 19 to move backward, driving the moving ring 44 to move backward. The moving ring 44 pulls the cable, and the cable pulls... The double-sided rack 9 moves backward, causing the shift fork 39 to open to both sides. This pushes the second transmission wheel 38 outward, engaging it with the drive wheel 49 on the second shaft 47. The drive wheels 49 on the first shaft 46 and the third shaft 48 then engage with the first transmission, thus driving the first shaft 46 and the second shaft 47. This separates the second shaft 47 from the transmission of the gearbox 50, thus separating the lifting window 4 from the electric power system to avoid affecting it. When the pressure rod retracts from the embedded groove 18, the elastic telescopic block 19 moves forward. The second transmission wheel 38, under the action of the compression spring 40, moves inward and engages with the drive wheel 49 on the second shaft 47. This drives the second shaft 47 with the first shaft 46 and the third shaft 48, thus driving the electric power assembly with the first shaft 46 and the third shaft 48.

[0039] A hollow slide 52 is provided on the window frame 1 outside the slide 6. The top of the slide 6 is connected to the top of the hollow slide 52. A counterweight 53 is embedded in the hollow slide 52 and moves up and down. The counterweight 53 is connected to the top of the lift window 4 by a steel cable 54. The two ends of the cable are fixed to the counterweight 53 and the lift window 4 by bolts. A pulley is installed on the top of the slide 6 by a bearing. The steel cable 54 is wound around the pulley. The weight of the counterweight 53 is less than the weight of the lift window 4, which reduces the force required for the lift window 4 to rise and makes it easier for the lift window to rise and fall.

[0040] The gearbox 50 is equipped with a worm gear mechanism 51. The worm is coaxial with the output shaft 55 and is fixed to the output shaft 55 by welding. The turbine is mounted on the lower part of the worm by bearing. A first bevel gear coaxial with the turbine is mounted on the front side of the worm gear by welding. A first bevel gear is also mounted on the second shaft 47 by welding. The two first bevel gears mesh, thus realizing the power transmission from the output shaft 55 to the second shaft 47.

[0041] When the stepper motor is powered off or the internal transmission of the gearbox 50 is disconnected, the output shaft 55 will not rotate. Therefore, the push plate 30 cannot push the pressing rod 31 outward, and the pawl 23 will not swing outward. When the lifting window 4 descends, the rotating shaft 11 rotates clockwise. Because the pawl 23 does not swing outward, when the rotating shaft 11 rotates clockwise, the pawl 23 will get stuck on the ratchet 22, restricting the clockwise rotation of the rotating shaft 11. This prevents the lifting mechanism 5 from malfunctioning and causing the lifting window 4 to descend rapidly, damaging the lifting window 4. The lifting window 4 can only be lowered by the stepper motor drive. The manual lifting assembly 14 can only raise the lifting window 4 to close it. When the lifting window 4 needs to be lowered, the output shaft 55 of the stepper motor rotates counterclockwise, and the moving sleeve 26 drives the push plate 30 to press the pressing rod 31. The pawl 23 swings outward under the action of the spiral groove 34 and the sliding rod 35, thus the pawl 23 gives way to the ratchet 22, and the rotating shaft 11 rotates clockwise, causing the lifting window 4 to descend.

[0042] The stepper motor that drives the output shaft 55 to rotate is connected to the stepper motor driver, which is connected to the output terminal of the microcontroller. A start and stop button is installed on the front face of the center bracket 2. The button is connected to the input terminal of the microcontroller, and the electric lifting of the window 4 is realized by the button.
