Description

Technical Field

[0001] This invention relates to the field of lift-up doors and windows, and more specifically to a top lifting device and a lift-up door and window. Background Technology

[0002] Products with lifting mechanisms generally refer to sliding doors or windows. In actual sliding, the product body slides by the bottom pulley structure contacting the lower rail. A lifting mechanism features a bottom pulley structure with extension and retraction functions. In lifting mode, the bottom pulley structure retracts, causing the pulleys to detach from the lower rail and disappear into the product body. The bottom structure of the product body then directly contacts the lower rail, and the product body's own weight ensures a tight connection, preventing it from sliding on the lower rail. Of course, lifting mechanisms also have a sliding mode. Even if the bottom pulley structure extends to its initial position and re-extends from the bottom of the product body, contacting the lower rail, the product body can continue to slide via the pulleys and the lower rail.

[0003] However, in the lifting mode, the main body of the product inevitably descends. Generally speaking, the top of the main body is reserved with sufficient length to be embedded in the upper slide rail. After the main body descends, the top of the main body can continue to be embedded in the upper slide rail to prevent the main body from tipping over. The top of the main body must have sufficient length to be embedded in the upper slide rail. However, in actual installation work, it is difficult to meet the requirements, or the construction requirements are particularly high. Moreover, due to installation errors or skipping procedures, the probability of the main body tipping over during long-term use is easily increased. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a top lifting device and a lifting door / window to avoid the product body from tipping over during long-term use, in order to address the above-mentioned deficiencies of the prior art.

[0005] The technical solution adopted by this invention to solve its technical problem is as follows: A top lifting device is provided, applied to products with a lifting mechanism. The lifting mechanism includes a lifting control component, a first linkage arm, and a bottom pulley structure disposed on the product body. The bottom pulley structure is disposed at the bottom of the product body. The lifting control component drives the first linkage arm to move, and causes the bottom pulley structure to move relative to the product body.

[0006] The lifting mechanism also includes a second linkage arm connected to the lifting control component, which drives the second linkage arm to move.

[0007] The top lifting device includes a fixed part, a movable part and a lifting part. The fixed part is fixed to the top of the product body. The movable part is connected to the second linkage arm and moves back and forth relative to the fixed part. The lifting part moves up and down relative to the fixed part under the drive of the movable part.

[0008] in,

[0009] The lifting unit rises when the bottom pulley structure retracts and falls when the bottom pulley structure extends, through the linkage of the lifting control component, the first linkage arm and the second linkage arm.

[0010] A preferred embodiment is that a guide structure is provided between the fixed part and the lifting part. The guide structure includes a lifting rail on one part and a lifting slider on the other part. The lifting slider slides along the lifting rail during the lifting movement of the lifting part.

[0011] A preferred embodiment is that a steering structure is provided between the moving part and the lifting part. The steering structure includes a steering rail provided on one part and a steering slider provided on the other part. The steering slider slides along the steering rail during the forward and backward movement of the moving part, so that the lifting part moves up and down relative to the moving part.

[0012] The preferred option is to use an inclined track for turning.

[0013] One preferred embodiment is that the lifting slider and the steering slider are a single raised structure, which is located on the side of the lifting part; the moving part and the fixed part are nested together, and the raised structure is sequentially inserted into the lifting track and the steering track.

[0014] A preferred embodiment is as follows: the fixed part is a shell structure, the movable part is moved back and forth within the shell structure, and the side of the movable part is attached to the side of the shell structure. The lifting part is embedded inside the movable part, and the protruding structure of the lifting part passes through the steering track of the movable part and the guide track of the fixed part from the inside to the outside.

[0015] A preferred embodiment is that the top of the fixed part is provided with a first opening, the top of the movable part is provided with a second opening, and the lifting part protrudes outward through the second opening and the first opening during the lifting process.

[0016] A preferred embodiment is that the top lifting device also includes a horizontally deployable pulley structure, with pulleys installed at both ends of the horizontally deployable pulley structure.

[0017] The technical solution adopted by this invention to solve its technical problem is: to provide a lift-up door / window, including a door / window body, a lift-up control component, a first linkage arm and a bottom pulley structure, and also including a top lifting device disposed at the top of the lift-up door / window; wherein,

[0018] The bottom pulley structure is located at the bottom of the door and window body. The lifting and operating component drives the first linkage arm to move, and causes the bottom pulley structure to move up and down relative to the door and window body.

[0019] The top lifting device includes a fixed part, a movable part, and a lifting part. The fixed part is fixed to the top of the door and window body. The movable part is connected to the second linkage arm and moves back and forth relative to the fixed part. The lifting part moves up and down relative to the fixed part under the drive of the movable part.

[0020] The lifting unit rises when the bottom pulley structure retracts and falls when the bottom pulley structure extends, through the linkage of the lifting control component, the first linkage arm and the second linkage arm.

[0021] The technical solution adopted by the present invention to solve its technical problem is: to provide a lifting system for a lifting door and window, including a lifting door and window, an upper slide rail and a lower slide rail, the lifting door and window sliding between the upper slide rail and the lower slide rail, the bottom pulley structure of the lifting door and window being engaged in the lower slide rail after being extended, and disengaging from the lower slide rail after being retracted; the lifting part of the top lifting device of the lifting door and window rising and engaging in the upper slide rail after the bottom pulley structure is retracted.

The top lifting device works in conjunction with the lifting control component. That is, while the lifting control component controls the movement of the bottom pulley structure through the first linkage arm, it also realizes the lifting movement through the second linkage arm, thereby avoiding the tipping of the product body during long-term use.

[0029] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0030] like Figures 1 to 5 As shown, the present invention provides a preferred embodiment of a top lifting device.

[0031] A top lifting device is applied to a product with a lifting mechanism. The lifting mechanism includes a lifting control component, a first linkage arm 600, and a bottom pulley structure 700, all mounted on the product body. The bottom pulley structure 700 is located at the bottom of the product body. The lifting control component moves the first linkage arm 600 and causes the bottom pulley structure 700 to move relative to the product body, such as extending or retracting. The lifting mechanism also includes a second linkage arm 500 connected to the lifting control component. The lifting control component moves the second linkage arm 500... The top lifting device includes a fixed part 100, a movable part 200, and a lifting part 300. The fixed part 100 is fixed to the top of the product body. The movable part 200 is connected to the second linkage arm 500 and moves back and forth relative to the fixed part 100. The lifting part 300 moves up and down relative to the fixed part 100 under the drive of the movable part 200. The lifting part 300 rises when the bottom pulley structure 700 retracts and falls when the bottom pulley structure 700 extends, through the linkage of the lifting control component, the first linkage arm 600, and the second linkage arm 500.

[0032] Specifically, a top lifting device is provided on the top of the product body. The top lifting device works in conjunction with the lifting control component. That is, while the lifting control component controls the extension and retraction of the bottom pulley structure 700 through the first linkage arm 600, it also realizes the lifting movement through the second linkage arm 500. The specific movement is as follows: after the bottom pulley structure 700 retracts, the product body sinks, causing the top of the product body to relatively descend in the upper slide rail. At this time, the lifting part 300 of the top lifting device rises, so that more structure can be embedded in the upper slide rail on the top of the product body. Similarly, after the bottom pulley structure 700 extends, the product body rises, causing the top of the product body to relatively rise in the upper slide rail. The distance between the top of the product body and the top of the upper slide rail is shortened or even brought close enough. At this time, the lifting part 300 of the top lifting device descends, freeing up more space.

[0033] In one embodiment, the lifting control assembly includes a rotary handle and a steering mechanism. The main function of the steering mechanism is to convert the rotational force of the rotary handle into a vertical force, that is, to drive the first linkage arm 600 and the second linkage arm 500 to move vertically up and down through the steering mechanism. Of course, there are many different specific structures for the rotary handle and the steering mechanism, which are conventional basic structures in the art and are not the technical points protected by this application, so they will not be described in detail here. Secondly, the first linkage arm 600 and the second linkage arm 500 are respectively provided with corresponding horizontal structures at the bottom and top of the product body. The vertical movement of the vertical structure drives the horizontal structure to move back and forth, thereby driving the bottom pulley structure 700 and the moving part 200 of the top lifting device to move back and forth. Of course, the lifting control assembly can also be an electrically driven structure, which drives the first linkage arm 600 and the second linkage arm 500 to move vertically up and down through gears or telescopic rods. However, this is also a conventional basic structure in the art and is not the technical point protected by this application, so it will not be described in detail here.

[0034] Regarding the bottom pulley structure 700, a corresponding structure is provided that allows for extension or retraction during the forward and backward movement of the product body, thereby enabling it to contact or disengage from the track. In products with a lifting mechanism, this is a necessary and very conventional structure, and it is not a technical point protected by this application, so it will not be described in detail here.

[0035] Regarding the lifting control component, the first linkage arm 600, and the bottom pulley structure 700 described above, please refer to relevant patents or products by searching for "lifting door" or "lifting window." Specific functions are described above. Furthermore, the actual structure of the second linkage arm 500 is consistent with that of the first linkage arm 600; please refer to... Figure 4 It mainly includes a linkage structure in two directions. Under the control of the lifting control component, the vertical structure 510 in the vertical direction can move up and down, so that the horizontal structure 520 in the horizontal direction can move back and forth. The back and forth movement refers to the movement along the top length direction of the product body, thereby driving the moving part 200 to move back and forth relative to the product body, that is, driving the moving part 200 to move back and forth relative to the fixed part 100. The lifting part 300 moves up and down relative to the fixed part 100 under the drive of the moving part 200. Among them, the end 511 of the vertical structure 510 drives the groove 521 of the horizontal structure 520 to move to the left and get into the protrusion 530 with a similar structure to achieve horizontal positioning. Conversely, the end 511 drives the horizontal structure 520 to move to the right and get away from the protrusion 530.

[0036] refer to Figure 5 Specifically with Figure 4Similarly, the end 611 of the vertical structure 610 drives the groove 621 of the horizontal structure 620 to move to the left and engage with the protrusion 631, which is similar in structure, to achieve horizontal positioning. Conversely, the end 611 drives the horizontal structure 620 to move to the right and disengage from the protrusion 631, thereby driving the bottom pulley structure 700 to move back and forth. Through related structures, such as inclined grooves, the pulleys of the bottom pulley structure 700 can be extended or retracted.

[0037] In one embodiment, a guide structure is provided between the fixed part 100 and the lifting part 300. The guide structure includes a lifting rail 102 disposed on one side and a lifting slider disposed on the other side. The lifting slider slides along the lifting rail 102 during the lifting movement of the lifting part 300. The guide structure enables the lifting slider to slide along the lifting rail 102, thereby achieving the lifting movement of the lifting part 300 relative to the fixed part 100, preventing the lifting part 300 from deviating from its position in the relative lateral direction during lifting, and improving the smoothness of the lifting movement. Simultaneously, a steering structure is provided between the moving part 200 and the lifting part 300. The steering structure includes a steering rail 202 disposed on one side and a steering slider disposed on the other side. The steering slider slides along the steering rail 202 during the forward and backward movement of the moving part 200, causing the lifting part 300 to move up and down relative to the moving part 200. With the cooperation of the steering structure, the lifting unit 300 can rise and fall as the moving unit 200 moves back and forth. However, due to the limitations of the guide structure, it can only move up and down within the range of movement of the lifting track 102.

[0038] Preferably, the steering track 202 is an inclined track. This means the steering slider can rise and fall gradually, improving the relative stability of the lifting unit 300's movement. Specifically, the lifting slider and the steering slider are a single protruding structure 301, positioned laterally on the lifting unit 300. The moving part 200 and the fixed part 100 are nested together, with the protruding structure 301 sequentially inserted into the lifting track 102 and the steering track 202. Because the protruding structure 301 is embedded in the lifting track 102, it can only move within the lifting range of the track, limiting its movement forward and backward. Simultaneously, the protruding structure 301 is also embedded in the steering track 202, performing lifting operations under the influence of the steering track 202, thus cooperating with the lifting track 102 to achieve lifting operations within a certain range. In particular, if the lifting track 102 is a vertical track, the protruding structure 301 can only move vertically, unable to move forward or backward, resulting in a more compact structure, simpler installation, and stronger stability.

[0039] In one embodiment, the fixing part 100 is a shell structure, the moving part 200 is disposed within the shell structure and moves back and forth, with the side of the moving part 200 fitting against the side of the shell structure. The lifting part 300 is embedded inside the moving part 200, and the protruding structure 301 of the lifting part 300 passes through the steering rail 202 of the moving part 200 and the guide rail of the fixing part 100 from the inside out. Furthermore, the top of the fixing part 100 is provided with a first opening 101, and the top of the moving part 200 is provided with a second opening 201. During the lifting process, the lifting part 300 passes through the second opening 201 and protrudes outward from the first opening 101.

[0040] Specifically, the outer shell structure has an internal cavity for housing the moving part 200 and the lifting part 300. The sides of the moving part 200 and the outer shell structure are two flat plates that fit together. The protruding structure 301 of the lifting part 300 passes sequentially through the steering rail 202 and guide rail on the two flat plates, making the structure more rational and facilitating workpiece production and assembly. Simultaneously, a first opening 101 and a second opening 201 are provided to allow the lifting part 300 to extend out of the first opening 101 and the second opening 201, increasing the overall height of the top lifting device.

[0041] In one embodiment, the top lifting device further includes a horizontally deployable pulley structure 400, with pulleys 420 respectively provided at both ends of the deployable arm 410 of the horizontally deployable pulley structure 400. The top lifting device is disposed in the upper slide rail, and the two pulleys 420 in the horizontally deployable pulley structure 400 respectively abut against both sides of the upper slide rail, facilitating the sliding of the product body. Preferably, the horizontally deployable pulley structure 400 is fixedly disposed in the fixing part 100.

[0042] The above are merely preferred embodiments of the present invention and are not intended to limit the scope of the present invention. All equivalent changes or modifications made in accordance with the claims of the present invention are covered by the present invention.
