Description

Technical Field

[0001] This invention belongs to the field of door and window technology, specifically relating to a lifting and sliding door and window system and a lifting method. Background Technology

[0002] Nowadays, the use of lift-sliding doors and windows in residential buildings is increasing. Due to the diverse applications of lift-sliding doors and windows, the specifications and sizes of the sashes (such as door sashes or window sashes) vary. In addition, the widespread use of multi-layer glass, and the need to integrate pulley structures on the sashes to lift or lower them, make the sashes generally quite heavy.

[0003] In related technologies, when lifting the fan, the handle needs to be rotated at a large angle, which is not conducive to user operation and is prone to causing the handle to be turned too quickly and causing a hand injury. Especially when the fan is heavy, the user needs to use more force to operate the handle. When the handle is turned too quickly and causes a hand injury, the force of the excessively fast rotation of the handle will also be greater, which may cause certain injuries to the user and poses certain safety hazards. Summary of the Invention

[0004] To overcome at least one of the defects described in the prior art, one objective of this invention is to provide a lifting and sliding door / window system. The handle is rotated outward by an angle β to the outward-pulling state to drive the transmission component upward, which in turn drives the front pulley unit to move downward relative to the sash component, thereby lifting the sash component. Because the limiting component moves to the locking state to keep the transmission component in the lifted state, the sash component can remain in the lifted state. The handle can be rotated inward to reset without driving the transmission component to reset, thus reducing the restoring force when the handle resets. This avoids the hand-slapping phenomenon caused by excessive handle rotation force, making it easier for the user to operate.

[0005] The second objective of this invention is to provide a lifting method for a sliding door and window system, which can avoid the hand-hitting phenomenon caused by excessive handle rotation force and make it easier for users to use.

[0046] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

These terms are primarily for the purpose of better describing the invention and its embodiments, and are not intended to limit the indicated devices, elements, or components to having a specific orientation, or to be constructed and operated in a specific orientation.

[0048] Furthermore, in addition to indicating direction or positional relationship, some of the aforementioned terms may also have other meanings. For example, the term "above" may also be used in certain situations to indicate a dependency or connection. Those skilled in the art can understand the specific meaning of these terms in this invention based on the specific circumstances.

[0049] Furthermore, the terms "installation," "setup," "equipped with," "connection," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral structure; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium, or an internal connection between two devices, components, or parts. Those skilled in the art can understand the specific meaning of these terms in this invention based on the specific circumstances.

[0050] Furthermore, the terms "first," "second," etc., are primarily used to distinguish different devices, components, or parts (which may be the same or different in specific type and construction), and are not intended to indicate or imply the relative importance or quantity of the indicated devices, components, or parts. Unless otherwise stated, "a plurality of" means two or more.

[0051] The technical solution of the present invention will be further described below with reference to the embodiments and accompanying drawings.

[0052] Example 1 See Figures 1 to 26This invention discloses a lifting and sliding door / window system, comprising: a mounting structure 10, which is mounted on a sash 20; an outward-pulling handle assembly 30, which includes a handle 301 rotatably connected to the mounting structure 10; a transmission assembly 40, which includes a transmission component 401 and a limiting component 402, both of which are movably connected to the mounting structure 10, and the handle 301 is throttle-connected to the transmission component 401; and a pulley assembly 50, which includes a front pulley unit 501, which is movably connected to the mounting structure 10 and throttle-connected to the transmission component 401; the handle 301 is rotated outward by an angle β to an outward-pulling state to drive the transmission component 401 upward, thereby driving the front pulley unit 501 downward relative to the sash 20, and the limiting component 402 moves to a locked state to keep the transmission component 401 in a lifted state.

[0053] In this invention, the handle 301 is rotated outward by an angle β to the outward pull state to drive the transmission component 401 to move upward, thereby driving the front pulley unit 501 to move downward relative to the fan component 20, thus lifting the fan component 20. Since the limiting component 402 moves to the locking state to keep the transmission component 401 in the lifted state, the fan component 20 can also be kept in the lifted state. The handle 301 can be rotated inward to reset without driving the transmission component 401 to reset. Therefore, the restoring force when the handle 301 resets is small, which can avoid the hand-slapping phenomenon caused by the large rotation force of the handle 301, making it convenient for users to use.

[0054] The aforementioned outward rotation of handle 301 refers to rotating handle 301 away from fan component 20, while inward rotation of handle 301 refers to rotating handle 301 towards fan component 20.

[0055] For example, fan 20 is a door fan or a window fan.

[0056] In use, the lifting sliding door and window system works in conjunction with the ground track 160. The front pulley unit 501 is slidably connected to the ground track 160. Therefore, when the front pulley unit 501 moves downward relative to the sash 20, the front pulley unit 501 moves away from the sash 20 in the height direction of the sash 20, thereby causing the sash 20 to rise. Of course, when the front pulley unit 501 swings upward relative to the sash 20, the front pulley unit 501 moves closer to the sash 20 in the height direction of the sash 20, thereby causing the sash 20 to fall.

[0057] In this embodiment of the invention, 0 < β ≤ 90°.

[0058] See Figure 20β is 60°, which means that the handle 301 only needs to be rotated outward by 60°. The user pulls the handle 301 outward to drive the transmission component 401 to slide upward. Thus, the angle of rotation of the handle 301 is small, and the handle 301 is rotated inward to reset, which is safer and easier to use.

[0059] If the handle 301 is rotated at a large angle, such as 180°, it may cause injury to the user when rotating the handle 301 outward or inward.

[0060] In this embodiment of the invention, the mounting structure 10 includes a first mounting member 101, which is disposed on the side of the fan member 20; the transmission assembly 40 further includes a first sliding member 403, a second sliding member 404, and a first elastic member 405. A first slide rail 111 is disposed on the first mounting member 101. The first sliding member 403 and the second sliding member 404 are slidably connected to the first slide rail 111. The first sliding member 403 is disposed near the starting end of the first slide rail 111, and the second sliding member 404 is disposed near the end of the first slide rail 111. The first end of the first elastic member 405 abuts against the first sliding member 403, and the second end of the first elastic member 405 abuts against the second sliding member 404. At least a portion of the handle 301 abuts against the first sliding member 403, and the second sliding member 404 is tractively connected to the transmission member 401.

[0061] The first elastic element 405 is a cylindrical spring.

[0062] The first slider 403 and the second slider 404 are nested together and are slidably connected.

[0063] The second sliding member 404 is sleeved on the outside of the first sliding member 403. The second sliding member 404 is disposed between the first mounting member 101 and the first sliding member 403, so that the mounting structure 10 and the first sliding member 403 guide the up and down sliding of the second sliding member 404. The first sliding member 403 is inserted into the inside of the second sliding member 404, so that the second sliding member 404 guides the up and down sliding of the first sliding member 403.

[0064] Both the first slider 403 and the second slider 404 can slide on the first slide rail 111. That is, the length of the first slide rail 111 is greater than the sum of the lengths of the first slider 403 and the second slider 404.

[0065] To reduce space occupation, the first slide rail 111 is set in the internal cavity of the first mounting member 101 or on the side wall of the first mounting member 101.

[0066] In this embodiment of the invention, the handle 301 includes a main body 311, a first extension 312, and a second extension 313 connected to each other. The first extension 312 and the second extension 313 are respectively disposed on both sides of the main body 311. The main body 311 is rotatably connected to the first mounting member 101. The first extension 312 extends out of the first mounting member 101. At least a portion of the second extension 313 is disposed near the starting end of the first slide rail 111 to abut against the first sliding member 403.

[0067] The main body 311 is rotatably connected to the first mounting member 101 via a handle pin 60. The main body 311 rotates around the handle pin 60, and the first extension 312 extends out of the first mounting member 101. The first extension 312 can be used as an operating part for the user.

[0068] See Figure 7 Since the distance between the edge of the second extension 313 and the rotation center of the main body 311 is different at different positions, during the outward rotation of the handle 301, the positions on the edge of the second extension 313 that are closer to the rotation center of the main body 311 and the positions on the edge of the second extension 313 that are farther from the rotation center of the main body 311 successively abut against the first sliding member 403, thereby pushing the first sliding member 403 to slide upward along the first slide rail 111, and the second sliding member 404 to slide upward along the first slide rail 111 until the second sliding member 404 slides to the end position of the first slide rail 111, the first elastic member 405 is compressed, thereby realizing the upward sliding of the transmission member 401.

[0069] To facilitate user operation, the first extension 312 is a long handle end and the second extension 313 is a short handle end. The included angle between the first extension 312 and the second extension 313 is θ, and the value of θ ranges from 90° to 150°.

[0070] For example, see Figure 20 The included angle θ between the first extension 312 and the second extension 313 is 125°. The included angle θ between the first extension 312 and the second extension 313, the angle β of the handle being pulled outward, the length of the second extension 313, and the shape of the second extension 313 are adapted to each other.

[0071] In this embodiment of the invention, the mounting structure 10 includes a second mounting member 102, which is disposed on the side of the fan member 20. The transmission assembly 40 also includes a third sliding member 406, and the second sliding member 404, the third sliding member 406 and the transmission member 401 are connected as one unit. The second mounting member 102 is provided with a second slide rail 121 parallel to the first slide rail 111, and the third sliding member 406 is slidably connected to the second slide rail 121.

[0072] In this embodiment of the invention, a third slide rail 122 is provided on the second mounting member 102, and the third slide rail 122 is arranged to cross the second slide rail 121. The limiting member 402 is slidably connected to the second slide rail 122. The transmission assembly 40 also includes a rotating member 407 and a second elastic member 408. The first end of the second elastic member 408 abuts against the limiting member 402, and the second end of the second elastic member 408 abuts against the second mounting member 102. The second elastic member 408 is used to drive the limiting member 402 to be kept in a locked state. The rotating member 407 has a protrusion 471. The rotating member 407 is rotatably connected to the second mounting member 102. The limiting member 402 is provided with a slot 421 for cooperating with the protrusion 471. The rotating member 407 drives the limiting member 402 to slide along the third slide rail 122 by rotation.

[0073] The second sliding member 404, the third sliding member 406, and the transmission member 401 can be connected as one piece by screws, or the second sliding member 404, the third sliding member 406, and the transmission member 401 can also be integrally formed, depending on the actual application scenario, and there is no limitation.

[0074] To facilitate the operation of the rotating component 407, a knob 302 can be rotatably connected to the first mounting component 101. The knob 302 and the rotating component 407 are connected as one piece or the knob 302 and the rotating component 407 are made as one piece. The knob 302 is located outside the first mounting component 101. When the user rotates the knob 302, the rotating component 407 can be rotated.

[0075] The second elastic element 408 is a torsion spring, which is sleeved on the mounting pin 70. The mounting pin 70 is fixed on the second mounting member 102. The first end of the torsion spring abuts against the limiting member 402, and the second end of the torsion spring abuts against the second mounting member 102. That is, the torsion spring is disposed between the limiting member 402 and the second mounting member 102.

[0076] Since the third slide rail 122 and the second slide rail 121 are arranged to cross each other, the limiting member 402 is slidably arranged on the sliding stroke of the third slide member 406 to limit the third slide member 406.

[0077] Furthermore, the third slide rail 122 is arranged perpendicularly to the second slide rail 121; the first slide rail 111 and the second slide rail 121 are both arranged along the height direction of the fan member 20, and the third slide rail 122 is arranged along the width direction of the fan member 20.

[0078] To reduce space occupation, the second slide rail 121 is set in the internal cavity of the second mounting member 102 or on the side wall of the second mounting member 102; the third slide rail 122 is set in the internal cavity of the second mounting member 102 or on the side wall of the second mounting member 102.

[0079] The rotating component 407 can be rotated clockwise to drive the limiting component 402 to slide to the right limit position along the second slide rail 121. (See reference) Figure 8 At this time, the first end of the second elastic element 408 undergoes elastic deformation to the right; the rotating element 407 can be rotated counterclockwise to drive the limiting element 402 to slide to the left limit position along the second slide rail 121. (See reference...) Figure 21 At this time, the first end of the second elastic element 408 resets to the left.

[0080] In this embodiment of the invention, the mounting structure 10 includes a third mounting member 103, which is disposed at the lower part of the fan member 20; the pulley assembly 50 also includes a corner member 502, a first connecting member 503, and a second front connecting member 504. The first end of the corner member 502 is rotatably connected to the third mounting member 103, the second end of the corner member 502 is rotatably connected to the transmission member 401, and the third end of the corner member 502 is rotatably connected to the first end of the first connecting member 503; the front pulley unit 501 includes a front mounting member 511, a front pulley 512, and a front lifting wheel 513. The second end of the connector 503 is rotatably connected to the front mounting member 511. The two ends of the second front connector 504 are rotatably connected to the third mounting member 103 and the front mounting member 511, respectively. That is, the first end of the second front connector 504 is rotatably connected to the third mounting member 103, and the second end of the second front connector 504 is rotatably connected to the front mounting member 511. A front lifting wheel 513 is rotatably connected to the rotatable connection position between the front mounting member 511 and the second front connector 504. A front guide portion 131 is provided on the third mounting member 103, and the front lifting wheel 513 rolls along the front guide portion 131.

[0081] It should be noted that the first end of the corner piece 502 is rotatably connected to the third mounting piece 103 via a corner pin 80, and the second end of the corner piece 502 is rotatably connected to the transmission piece 401 via a push-pull pin 90; the third end of the corner piece 502 is rotatably connected to the first end of the first connecting piece 503 via a first connecting pin 100; the second end of the first connecting piece 503 is rotatably connected to the front mounting piece 511 via a second connecting pin 110; the first end of the second front connecting piece 504 is rotatably connected to the third mounting piece 103 via a first upper lifting pin 120; the second end of the second front connecting piece 504 is rotatably connected to the front mounting piece 511 via a first lower lifting pin 130; and the front lifting wheel 513 is sleeved outside the first lower lifting pin 130, and the front lifting wheel 513 is rotatably connected to the first lower lifting pin 130.

[0082] In use, the lifting and sliding door and window system is used in conjunction with the ground track 160, and the front pulley 512 of the front pulley unit 501 is slidably connected to the ground track 160.

[0083] The specific usage process of this lift-up sliding door and window system is as follows: See Figures 1 to 15 The limiting member 402 is in the unlocked state, meaning it is at the right limit of its travel. The second elastic member 408 is compressed between the limiting member 402 and the second mounting member 102. The second sliding member 404, the third sliding member 406, and the transmission member 401 are all at the lower limit of their travel (descending state) under the influence of gravity. The first elastic member 405 is compressed between the first sliding member 403 and the second sliding member 404. The front pulley unit 501 moves upward to the upper limit of its travel (lifting state), meaning the front lifting wheel 513 is at the upper limit of the front guide portion 131. (See reference...) Figure 14 At this time, fan component 20 is in a descending state, see reference. Figure 1 .

[0084] See Figures 16 to 26 Pulling the handle 301 causes the second extension 313 to rotate to its upper limit position of rotational stroke. The first sliding member 403 slides upward along the first slide rail 111, and the second sliding member 404 slides upward along the first slide rail 111 until it reaches the end position of the first slide rail 111. The first elastic member 405 is in a compressed state. Since the second sliding member 404, the third sliding member 406, and the transmission member 401 are connected as one unit, the third sliding member 406 slides upward along the third slide rail 122, and the second sliding member 404, the third sliding member 406, and the transmission member 401 are all at the upper limit of their active stroke. Position (lifted state); the second elastic member 408 pushes the limiting member 402 to slide to the left limit position of its active stroke by resetting, thereby causing the limiting member 402 to enter the locked state. Since the limiting member 402 slides to the stroke of the third sliding member 406, the limiting member 402 restricts the third sliding member 406 from sliding downward; the transmission member 401 drives the front pulley unit 501 to move downward to the lower limit position of its active stroke through the corner member 502, the first connecting member 503, and the second connecting member 504, that is, the front lifting wheel 513 is at the lower limit position of the front guide part 131 (lowering state); at this time, the fan member 20 is in the lifted state, see reference. Figure 16 .

[0085] Next, the user releases the handle 301, the first elastic element 405 resets, and the first sliding element 403 slides downward under its own weight and the elastic force of the first elastic element 405. When the first sliding element 403 slides downward, it pushes the second extension 313 of the handle 301, causing the handle 301 to rotate inward around the handle pin 60 to reset, until the first sliding element 403 slides downward to the initial end position of the first slide rail 111. At this time, the fan 20 is still in the raised state.

[0086] If the user needs to change the fan 20 from the raised state to the lowered state, the limit member 402 needs to be unlocked first. If the limit member 402 always restricts the third slider 406 from moving downward, the user pulling the handle 301 will not drive the integrated structure of the second slider 404, the third slider 406 and the transmission member 401 to move, and thus will not drive the front pulley unit 501 to move, and thus will not change the state of the fan 20.

[0087] When the user needs to change the fan 20 from the raised state to the lowered state, the user rotates the rotating component 407 clockwise. Its protrusion 471 pushes the limiting component 402 to slide along the second slide rail 221 to the right limit position of the active stroke (unlocked state). At this time, the second sliding component 404, the third sliding component 408, and the transmission component 401, under the combined action of their own gravity and the restoring force of the first elastic component 405, simultaneously slide downward along their respective slide rails to the lower limit position of the active stroke (lowered state). The first elastic component 405 is compressed between the first sliding component 403 and the second sliding component 404. (See reference...) Figure 7 The front pulley unit 501 moves upward to the upper limit position of its travel stroke (lifted state), that is, the front lifting wheel 513 is at the upper limit position of the front guide 131; at this time, the fan member 20 is in the lowered state, see reference. Figure 1 Then, the user releases the rotating part 407.

[0088] The front pulley unit 501 can move upward or downward relative to the third mounting member 103.

[0089] During the upward movement of the front pulley unit 501 relative to the third mounting member 103, the front lifting wheel 513 follows the second front connecting member 504 and swings counterclockwise around the first upper lifting pin 120. That is, the front lifting wheel 513 follows the second front connecting member 504 and revolves counterclockwise around the first upper lifting pin 120, thereby driving the front pulley unit 501 as a whole to rise relative to the third mounting member 103. On the other hand, the front lifting wheel 513 itself rotates around the first lower lifting pin 130. Thus, during the counterclockwise swing of the front lifting wheel 513 following the second connecting member 504 around the first upper lifting pin 120, the front lifting wheel 513 can roll upward along the front guide portion 131 to reduce the sliding friction between the front lifting wheel 513 and the front guide portion 131, making the movement of the front pulley unit 501 smoother.

[0090] Similarly, during the downward movement of the front pulley unit 501 relative to the third mounting member 103, the front lifting wheel 513 follows the second front connecting member 504 and swings clockwise around the first upper lifting pin 120. That is, the front lifting wheel 513 follows the second front connecting member 504. The front pulley unit 501 rotates clockwise around the first upper lifting pin 120, thereby causing the entire front pulley unit 501 to descend relative to the third mounting member 103. On the other hand, the front lifting wheel 513 rotates around the first lower lifting pin 130. As the front lifting wheel 513 follows the second connecting member 504 and swings clockwise around the first upper lifting pin 120, the front lifting wheel 513 can roll downward along the front guide portion 131 to reduce the sliding friction between the front lifting wheel 513 and the front guide portion 131, making the movement of the front pulley unit 501 smoother. Thus, by increasing the diameter of the front lifting wheel 513, the pushing force applied by the user to the transmission member 401 can be reduced, that is, the pushing force applied by the user to the handle 301 can be reduced, making the lifting of the fan member 20 smoother and less strenuous.

[0091] In this embodiment of the invention, the third mounting component 103 includes a front body 132 and a front support portion 133, and a front guide portion 131 is provided at the included angle between the front body 132 and the front support portion 133.

[0092] In this embodiment of the invention, the mounting structure 10 further includes a fourth mounting member 104, which is disposed at the lower part of the fan member 20; the pulley assembly 50 includes a rear pulley unit 505 and a second rear connecting member 506; the rear pulley unit 505 includes a rear mounting member 551, a rear pulley 552 and a rear lifting wheel 553, the two ends of the second rear connecting member 506 are respectively rotatably connected to the fourth mounting member 104 and the rear mounting member 551, and the front mounting member 511 and the rear mounting member 551 are connected as one unit by a third connecting member 507; the rear lifting wheel 553 is rotatably connected to the rotatable connection position of the rear mounting member 551 and the second rear connecting member 506, and a rear guide portion 141 is provided on the fourth mounting member 104, and the rear lifting wheel 553 rolls along the rear guide portion 141.

[0093] In use, the lifting and sliding door and window system works in conjunction with the ground track 160, and the rear pulley 552 of the rear pulley unit 505 is slidably connected to the ground track 160.

[0094] The first end of the second rear connector 506 is rotatably connected to the fourth mounting member 104 via the second upper lifting pin 140, the second end of the second rear connector 506 is rotatably connected to the rear mounting member 551 via the second lower lifting pin 150, and the rear lifting wheel 553 is sleeved on the second lower lifting pin 150 and is rotatably connected to the second lower lifting pin 150.

[0095] Similarly, the rear pulley unit 505 can move upward or downward relative to the fourth mounting member 104.

[0096] During the upward movement of the rear pulley unit 505 relative to the fourth mounting member 104, the rear lifting wheel 553 follows the second rear connecting member 506 and swings counterclockwise around the second upper lifting pin 140. That is, the rear lifting wheel 553 follows the second rear connecting member 506 and revolves counterclockwise around the second upper lifting pin 140, thereby driving the rear pulley unit 505 as a whole to rise relative to the fourth mounting member 104. On the other hand, the rear lifting wheel 553 itself rotates around the second lower lifting pin 150. Thus, during the counterclockwise swing of the rear lifting wheel 553 following the second rear connecting member 506 around the second upper lifting pin 140, the rear lifting wheel 553 can roll upward along the rear guide portion 141 to reduce the sliding friction between the rear lifting wheel 553 and the rear guide portion 141, making the movement of the rear pulley unit 505 smoother.

[0097] Similarly, during the downward movement of the rear pulley unit 505 relative to the fourth mounting member 104, the rear lifting wheel 553 follows the second rear connecting member 506 and swings clockwise around the second upper lifting pin 140. That is, the rear lifting wheel 553 follows the second rear connecting member 506. The rear pulley unit 505 rotates clockwise around the second upper lifting pin 140, thereby causing the rear pulley unit 505 to descend relative to the fourth mounting member 104. On the other hand, the rear lifting wheel 553 rotates around the second lower lifting pin 150. As the rear lifting wheel 553 follows the second rear connecting member 506 and swings clockwise around the second upper lifting pin 140, the rear lifting wheel 553 can roll downward along the rear guide portion 141 to reduce the sliding friction between the rear lifting wheel 553 and the rear guide portion 141, making the movement of the rear pulley unit 505 smoother. Thus, by increasing the diameter of the rear lifting wheel 553, the pushing force applied by the user to the transmission member 401 can be reduced, that is, the pushing force applied by the user to the handle 301 can be reduced, making the lifting of the fan member 20 smoother and less strenuous.

[0098] Thus, the rear pulley unit 505 moves with the front pulley unit 501 via the third connecting member 507. If the front pulley unit 501 moves upward, the rear pulley unit 505 also moves upward with the front pulley unit 501. If the front pulley unit 501 moves downward, the rear pulley unit 505 also moves downward.

[0099] In this embodiment of the invention, the fourth mounting component 104 includes a rear body 142 and a rear support portion 143, and a rear guide portion 141 is provided at the included angle between the rear body 142 and the rear support portion 143.

[0100] Example 2 The present invention also discloses a lifting method for a lifting sliding door and window system, including the use of the above-mentioned lifting sliding door and window system; when the limiting member 402 is in the unlocked state, the user pulls the handle 301 to drive the sash 10 from the lowered state to the raised state; when the limiting member 402 is in the locked state, the user releases the handle 301 to reset the handle 301, and the sash 10 remains in the raised state.

[0101] The lifting method of the lifting and sliding door and window system in this invention can avoid the hand-hitting phenomenon caused by the large rotation force of the handle 301, making it easier for users to use.
