Description

Technical Field

[0001] This utility model relates to the field of lift-up window technology, specifically a side-pressing mechanism for lift-up windows and a lift-up window. Background Technology

[0002] Pull-out windows generally consist of a fixed frame, a fixed window sash fixedly installed within the fixed frame, and a movable window sash installed within the fixed frame that can move up and down to open and close the window. Because they open and close vertically, they offer advantages such as excellent ventilation, unobstructed views, and space-saving design, and are currently widely used in balconies, shop windows, and other similar applications. However, to ensure smooth up-and-down movement and minimize friction, a certain gap needs to be maintained between the movable and fixed window sashes. This results in a common problem of poor sealing in existing pull-out windows, affecting their rainproof, soundproof, and thermal insulation performance. Utility Model Content

[0003] In order to overcome the defects in the prior art, one of the objectives of this utility model is to provide a side-pressing mechanism for a pull-up window, which can drive the movable window sash to move laterally toward the fixed window sash to increase the sealing performance of the pull-up window. The second objective is to provide a pull-up window using the aforementioned side-pressing mechanism.

[0004] One of the objectives of this utility model is achieved through the following technical solution:

[0005] A side-pressing mechanism for a pull-up window includes a mounting base, a side-pressing plate, and a transmission rod. One side of the side-pressing plate has a sliding part for laterally sliding connection with the mounting base along the Y-axis direction, and the other side extends laterally beyond the side of the mounting base and has a hook-up part extending along the X-axis direction. The side-pressing plate has a guide groove, which includes an inclined groove section that is inclined in the YZ plane. The transmission rod has a guide post extending along the X-axis direction, which extends into the guide groove. The transmission rod can reciprocate up and down relative to the mounting base along the Z-axis direction, thereby applying a force along the Y-axis direction to the side-pressing plate through the cooperation of the guide post and the inclined groove section.

[0006] As a preferred technical solution, the sliding part and the side pressure plate are two separate structures that can be separated. The guide groove is provided on the sliding part, and the side pressure plate and the sliding part are connected by the position adjustment mechanism. The position adjustment mechanism can adjust the lateral position of the side pressure plate relative to the sliding part and lock it in place.

[0007] As a preferred technical solution, the position adjustment mechanism includes a first transverse rack and a second transverse rack respectively disposed on the contact surfaces of the side pressure plate and the sliding part and meshing with each other, a transverse elongated hole and a screw hole respectively disposed on the side pressure plate and the sliding part, and a locking screw passing through the transverse elongated hole and threadedly connected to the screw hole; it also includes at least one set of first transverse sliding grooves and first sliders respectively disposed on the side pressure plate and the sliding part and laterally slidingly connected.

[0008] As a preferred technical solution, the mounting base includes a detachably connected base plate and a cover plate. The sliding part is engaged between the base plate and the cover plate and can slide laterally back and forth within its limiting range. When the cover plate is removed from the base plate, the sliding part can be directly removed or placed. The cover plate is also provided with an avoidance notch for the side pressure plate to connect with the sliding part.

[0009] As a preferred technical solution, the mounting base and the sliding part are respectively provided with at least one set of second transverse sliding grooves and second sliders that are laterally connected, as well as at least one supporting plane and transverse protrusion that are laterally engaged.

[0010] As a preferred technical solution, the cover plate is connected to the front of the base plate by a number of screws, wherein at least two screws are provided with guide portions protruding from the back of the base plate, the transmission rod is located on the back of the base plate, and the transmission rod is provided with at least one first vertical elongated hole, the guide portion extends into the first vertical elongated hole and can be limited and guided through it, so that the transmission rod can only move up and down relative to the mounting base, the base plate is provided with a second vertical elongated hole, and the guide post passes through the second vertical elongated hole and extends into the guide groove.

[0011] As a preferred technical solution, the mounting part includes a mounting post provided on the side pressure plate and protruding along the X-axis direction, and a roller provided on the mounting post.

[0012] As a preferred technical solution, the guide groove further includes vertical sections disposed at the upper and lower ends of the inclined groove section, the two vertical sections being connected to the upper and lower ends of the inclined groove section respectively and forming an arc transition.

[0013] The second objective of this utility model is achieved through the following technical solution:

[0014] A pull-out window includes a fixed frame, a fixed window sash fixedly installed within the fixed frame, and a movable window sash movably installed within the fixed frame and capable of reciprocating up and down to open and close the window. At least one side-pressing mechanism is provided between the movable window sash and the left and right side frames of the fixed frame. The mounting base is fixedly installed on the side frame of the movable window sash. The side frame of the fixed frame is provided with a first vertical sliding groove into which the hanging part extends. The movable window sash is provided with a drive handle and / or an electric drive mechanism that is connected to the drive rod, thereby driving the drive rod to move up and down. In turn, the reaction force applied by the fixed frame to the hanging part drives the movable window sash to move laterally relative to the fixed window sash.

[0015] As a preferred technical solution, at least one balancer is provided between the movable window sash and the left and right side frames of the fixed frame. The balancer includes a spring seat and a slider. The spring seat contains several sets of springs, each spring extending from the spring seat and connected to the slider. The side frame of the fixed frame also has a second vertical groove for accommodating the balancer. The second vertical groove is arranged parallel to the first vertical groove. The spring seat is fixedly installed in the second vertical groove, and the slider is slidably connected within the second vertical groove and connected to the side frame of the movable window sash via a pin. By providing the balancer, the spring force of the springs can be used to distribute the weight of the movable window sash, making it easier to open the window using an electric window opener or manually.

[0016] As a preferred technical solution, a sealing strip is also provided between the movable window sash and the fixed window sash. When the movable window sash moves laterally toward the fixed window sash under the action of the side pressure mechanism, it can squeeze the sealing strip to improve the airtightness.

[0017] Compared with the prior art, the side-pressing mechanism and the pull-up window provided by this utility model have the following advantages: By setting the side-pressing mechanism, when the movable window sash is closed, it can be driven to move laterally towards the fixed window sash to reduce the gap between the two, thereby improving the sealing performance of the pull-up window; by setting the other side of the side-pressing plate to protrude beyond the side of the mounting base and setting a hook part thereon, it is easy to install the side-pressing mechanism and the balancer on both sides of the pull-up window at the same time, so that when the hook part of the side-pressing mechanism slides up and down along the fixed frame, it will not interfere with the parts installed inside the fixed frame. The balancer causes interference; by setting a position adjustment mechanism, the lateral position of the hook part can be easily adjusted, thereby facilitating installation and increasing its applicability. By setting a first lateral rack and a second lateral rack that mesh with each other on the contact surface of the side pressure plate and the sliding part, the side pressure plate and the sliding part can be locked more securely, preventing loosening. By setting a mounting base including a detachably connected base plate and cover plate, the sliding part and the mounting base can be easily disassembled and assembled. By setting an avoidance notch on the cover plate, the installation of the side pressure plate and the sliding part, as well as the lateral position adjustment of the side pressure plate relative to the sliding part, can be achieved without removing the cover plate.

Detailed Implementation

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely for explaining the present utility model and are not intended to limit the present utility model.

[0027] It should be noted that when one component is referred to as "connecting," "installing," or "transmitting a connection" to another component, it can be a direct connection, installation, or transmission connection to the other component, or an indirect connection, installation, or transmission connection through an intervening component. Furthermore, the terms "upper," "lower," and similar expressions used herein are for illustrative purposes only and do not indicate the only possible implementation; "first," "second," and similar words do not indicate any order, quantity, or importance, but are merely used to distinguish different components; "a" or "one," and similar words do not indicate a quantity limitation, but rather indicate the presence of at least one; "several," "multiple," and similar words indicate two or more.

[0028] Example 1:

[0029] like Figure 1-4 As shown, a side-pressing mechanism for a pull-up window includes a mounting base 1, a side-pressing plate 2, and a transmission rod 3. One side of the side-pressing plate 2 is provided with a sliding part 23 for lateral sliding connection with the mounting base 1 along the Y-axis direction. The other side of the side-pressing plate 2 extends laterally beyond the side of the mounting base 1 and is provided with a hook part 21 extending along the X-axis direction (it should be noted that "extending along the Y-axis direction" here refers to this). The side-pressing plate 2 is provided with a guide groove 22, which includes an inclined groove section 221. The inclined groove section 221 is inclined in the YZ plane. The transmission rod 3 is provided with a guide post 31 extending along the X-axis direction. The guide post 31 extends into the guide groove 22. The transmission rod 3 can move up and down relative to the mounting base 1 along the Z-axis direction, thereby applying a force along the Y-axis direction to the side-pressing plate 2 through the cooperation of the guide post 31 and the inclined groove section 221.

[0030] The side-pressing mechanism for the pull-up window provided in this embodiment is installed on the pull-up window. The specific installation method is shown in Embodiment 2. When in use, when the transmission rod 3 is driven to move up and down by an external force (such as rotating the drive handle of the movable window sash), the guide post 31 will move up and down in the guide groove 22. When the guide post 31 moves to the inclined groove section 221, the guide post 31 and the inclined groove section 221 can apply a force along the Y-axis to the side-pressing plate 2. The reaction force applied to the hook part 21 by the fixed frame can drive the movable window sash to move laterally relative to the fixed window sash. Thus, when the movable window sash is closed, the side-pressing mechanism can be used to drive the movable window sash to move laterally towards the fixed window sash to reduce the gap between the two and improve the sealing performance of the pull-up window. In addition, by setting the other side of the side pressure plate 2 to protrude beyond the side of the mounting base 1 and setting the hook part 21 thereon, it is easy to install the side pressure mechanism and the balancer on both sides of the pull-up window at the same time, so that when the hook part 21 of the side pressure mechanism slides up and down along the fixed frame, it will not interfere with the balancer installed in the fixed frame.

[0031] In a preferred embodiment, the sliding part 23 and the side pressure plate 2 are two separable independent structures. The guide groove 22 is disposed on the sliding part 23. The side pressure plate 2 and the sliding part 23 are connected by the position adjustment mechanism, which can adjust the lateral position of the side pressure plate 2 relative to the sliding part 23 and lock it in place. Preferably, the position adjustment mechanism includes a first transverse rack 241 and a second transverse rack 242 respectively disposed on the contact surfaces of the side pressure plate 2 and the sliding part 23 and meshing with each other, a transverse elongated hole 243 and a screw hole 244 respectively disposed on the side pressure plate 2 and the sliding part 23, and a locking screw passing through the transverse elongated hole 243 and threadedly connected to the screw hole 244; it also includes two sets of first transverse sliding grooves 245 and first sliders 246 respectively disposed on the side pressure plate 2 and the sliding part 23 and slidably connected in the transverse direction. By setting a position adjustment mechanism, the lateral position of the hook part 21 can be easily adjusted, thereby facilitating installation and increasing its applicability. By setting a first lateral rack 241 and a second lateral rack 242 that mesh with each other on the contact surface of the side pressure plate 2 and the sliding part 23, the side pressure plate 2 and the sliding part 23 can be locked more securely, preventing loosening.

[0032] In a preferred embodiment, the mounting base 1 includes a detachably connected base plate 11 and a cover plate 12. The sliding part 23 is engaged between the base plate 11 and the cover plate 12 and can slide laterally within its limiting range. When the cover plate 12 is removed from the base plate 11, the sliding part 23 can be directly removed or placed. The cover plate 12 is also provided with a clearance notch 121 for the side pressure plate 2 to connect with the sliding part 23. By providing the mounting base 1 with a detachably connected base plate 11 and a cover plate 12, it is convenient to assemble and disassemble the sliding part 23 with the mounting base 1. By providing a clearance notch 121 on the cover plate 12, the installation of the side pressure plate 2 and the sliding part 23, as well as the lateral position adjustment of the side pressure plate 2 relative to the sliding part 23, can be achieved without removing the cover plate 12.

[0033] In a preferred embodiment, the base plate 11 and the sliding part 23 are respectively provided with several sets of second transverse sliding grooves 111 and second sliders 231 that are laterally connected and cooperate in sliding. The cover plate 12 and the sliding part 23 are respectively provided with a support plane 121 and a transverse protrusion 232 that cooperate in abutting. This solution can guide and limit the sliding of the sliding part 23 relative to the mounting base 1, reduce sliding friction, and make the sliding of the two more smooth.

[0034] In a preferred embodiment, the cover plate 12 is connected to the front of the base plate 11 by a plurality of screws 13, wherein at least two screws 13 are provided with guide portions 131 protruding from the back of the base plate 11. The transmission rod 3 is located on the back of the base plate 11, and the transmission rod 3 is provided with at least one first vertical elongated hole 32. The guide portion 131 extends into the first vertical elongated hole 32 and can be used for limiting and guiding, so that the transmission rod 3 can only move up and down relative to the mounting base 1. The base plate 11 is provided with a second vertical elongated hole 112, and the guide post 31 passes through the second vertical elongated hole 112 and extends into the guide groove 22. This solution can not only use screws 13 to connect the cover plate 12 and the base plate 11, but also use the protruding parts of the screws 13 to provide guide portions 131, which, together with the first vertical elongated hole 32 on the transmission rod 3, can limit and guide the movement of the transmission rod 3.

[0035] In a preferred embodiment, the mounting portion 21 includes a mounting post 211 protruding along the X-axis on the side pressure plate 2 and a roller 212 on the mounting post 211. In this embodiment, by providing the roller 212, during use, the roller 212 on the mounting portion 21 rolls up and down along the first vertical groove on the fixed frame. This not only utilizes the reaction force applied to the mounting portion 21 by the fixed frame to drive the movable window sash to move laterally relative to the fixed window sash, but also uses the cooperation between the roller 212 and the first vertical groove to guide the up and down movement of the movable window sash.

[0036] As a preferred embodiment, the guide groove 22 further includes vertical sections 222 disposed at the upper and lower ends of the inclined groove section 221. The two vertical sections 222 are respectively connected to the upper and lower ends of the inclined groove section 221 and form an arc transition. In use, when the transmission rod 3 moves to the upper and lower stop points, the guide post 31 is just located within the vertical section 222. This design facilitates positioning and prevents the guide post 31 from slipping when it is located in the inclined groove section 221.

[0037] Example 2:

[0038] like Figure 5-6As shown, this embodiment provides a pull-out window, including a fixed frame 101, a fixed window sash 102 fixedly installed within the fixed frame 101, and a movable window sash 103 movably installed within the fixed frame 101 and capable of reciprocating up and down to open and close the window. At least one side-pressing mechanism as described in Embodiment 1 is provided between the movable window sash 103 and the left and right side frames of the fixed frame 101. The mounting base 1 is fixedly installed on the side frame of the movable window sash 103. The side frame of the fixed frame 101 is provided with a first vertical groove 1011 into which the hanging part 21 extends. Preferably, the width of the first vertical groove 1011 is slightly larger than the diameter of the roller 212 on the hanging part 21. The movable window sash 103 is provided with a drive handle and / or an electric drive mechanism that drives the transmission rod 3 to move up and down, thereby driving the movable window sash 103 to move laterally relative to the fixed window sash 102 through the reaction force applied to the hanging part 21 by the fixed frame 101. It should be noted that in Embodiment 1, the X-axis direction is the left-right direction of the pull-up window, the Y-axis direction is the inside-outside direction of the pull-up window, and the Z-axis direction is the up-down direction of the pull-up window.

[0039] The pull-up window provided in this embodiment, by setting a side-pressure mechanism, can drive the movable window sash 103 to move laterally toward the fixed window sash 102 when the window is closed, thereby reducing the gap between the two and improving the sealing performance of the pull-up window.

[0040] As a preferred embodiment, at least one balancer 4 is provided between the movable window sash 103 and the left and right side frames of the fixed frame 101. The balancer 4 includes a spring seat 41 and a slider 42. The spring seat 41 is provided with a plurality of springs 411. Each spring 411 extends out from the spring seat 411 and is connected to the slider 42. The side frame of the fixed frame 101 is also provided with a second vertical groove 1012 for accommodating the balancer 4. The second vertical groove 1012 is arranged in parallel with the first vertical groove 1011. The spring seat 41 is fixedly installed in the second vertical groove 1012, and the slider 42 is slidably connected in the second vertical groove 1012 and connected to the side frame of the movable window sash 103 through a pin. By setting the balancer 4, the elasticity of the coil spring 411 can be used to distribute the weight of the movable window sash 103, making it easier to open the window by electric window opening device or manually. Moreover, by setting the other side of the side pressure plate 2 to protrude beyond the side of the mounting base 1 and setting the hook part 21 on it, it is easy to install the side pressure mechanism and the balancer 4 on both sides of the pull-up window at the same time, so that when the hook part 21 of the side pressure mechanism slides up and down along the fixed frame 101, it will not interfere with the balancer 4 installed in the fixed frame 101.

[0041] As a preferred embodiment, a sealing strip (not shown in the figure) is also provided between the movable window sash 103 and the fixed window sash 102. When the movable window sash 103 moves laterally toward the fixed window sash 102 under the action of the side pressure mechanism, it can squeeze the sealing strip to improve the airtightness.

[0042] The above description is merely a preferred embodiment of this application and an explanation of the technical principles employed. Those skilled in the art should understand that the scope of the utility model involved in this application is not limited to the technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the inventive concept. For example, technical solutions formed by substituting the above features with (but not limited to) technical features with similar functions disclosed in this application.
