Abstract
Description
Technical Field
[0001] This utility model belongs to the field of door and window technology, specifically relating to a drifting inward tilt window hinge, hardware system and drifting inward tilt window. Background Technology
[0002] A drifting tilt-and-turn window is a product that can slide the window sash out of the window frame and can be pushed and pulled in a straight line or tilted inward at the top of the window sash to slide out of the window frame. It has the characteristics of small space occupation, avoiding conflict with indoor items, good ventilation, and good sealing.
[0003] To enable the window sash to slide horizontally or tilt inward from the window frame, a hinge needs to be installed between the window sash and the frame. This hinge must effectively limit the movement distance of the window sash, whether it moves forward or backward, or tilts inward, to ensure stable sliding, tilting, and sealing. Existing tilting-in window hinges typically include a sliding mechanism, a linkage assembly, and a window sash fixing block. The sliding mechanism is slidably mounted on the window frame, the window sash fixing block is fixed to the window sash, and the linkage assembly connects the sliding mechanism and the fixing block. The linkage assembly enables the window sash to slide horizontally or tilt inward, and a limiting structure is installed on the linkage assembly to restrict the movement of the linkage assembly and thus limit the horizontal or inward tilting of the window sash.
[0004] However, placing the limiting structure on the linkage assembly has two drawbacks: firstly, its reliability is poor, and secondly, its structure is relatively complex. In particular, the linkage assembly generally contains multiple links, which makes assembly and debugging difficult. Utility Model Content
[0005] In order to overcome the above-mentioned shortcomings of the prior art, the purpose of this utility model is to provide a drifting tilt-in window hinge. The hinge has a simple and reliable structure, good limiting effect, and is conducive to improving the stability of window sash translation, sliding or tilting.
[0006] The technical solution adopted by this utility model to solve its technical problem is:
[0007] A drifting inward tilt-and-turn window hinge, characterized in that it includes a sliding mechanism, a connecting rod, and a base; the sliding mechanism is slidably mounted on the window frame, the base is fixedly connected to the window sash, one end of the connecting rod is rotatably connected to the sliding mechanism, and the other end of the connecting rod is rotatably connected to the base;
[0008] The base is provided with a boss and an elastic limiting structure;
[0009] The connecting rod is provided with an extension limiting post and a retraction limiting post, which extend towards one side of the base and are located on both sides of the rotational connection point between the connecting rod and the base. A boss protrudes from the base and is located on the side of the base near the window frame. The boss has a first recess and a second recess on the side facing the connection between the connecting rod and the base, with the first recess protruding between them. The first recess is used to mate with the extension limiting post, and the second recess is used to mate with the retraction limiting post. The boss limits the maximum extension angle and the minimum retraction angle of the connecting rod by blocking the extension limiting post and the retraction limiting post.
[0010] When the connecting rod is at its maximum extension angle, the window sash is located outside the window frame, and the elastic limiting structure prevents the connecting rod from rotating in the direction of retracting into the window frame by an overcoming elastic force; when the connecting rod is at its minimum extension angle, the window sash is located inside the window frame, and the elastic limiting structure prevents the connecting rod from rotating in the direction of extending out of the window frame by an overcoming elastic force.
[0011] In a preferred embodiment of this utility model, the base is provided with a protruding fixing post, and a bushing is provided on the fixing post; a fixing member is provided at one end of the connecting rod near the base, and the fixing member is adapted to the bushing to realize the rotatable connection between the connecting rod and the base.
[0012] In a preferred embodiment of this utility model, the elastic limiting structure includes a rotating seat, an elastic element, and a limiting guide; one end of the rotating seat is rotatably connected to the base, the limiting guide is slidably disposed on the rotating seat, the elastic force of the elastic element acts on the rotating seat and the limiting guide, and one end of the limiting guide extends out of the rotating seat and is rotatably connected to the connecting rod.
[0013] Preferably, when the connecting rod is at its maximum extension angle or minimum retraction angle, the direction of the force exerted by the limiting guide on the connecting rod is outside the rotational connection point between the connecting rod and the base.
[0014] Preferably, the rotating seat has an inner cavity, and the elastic element is disposed in the inner cavity; the limiting guide includes a first post and a second post, the first post and the second post being perpendicular to each other; the elastic force of the elastic element acts on the first post, and the second post is rotatably connected to the connecting rod.
[0015] In a preferred embodiment of this utility model, the sliding mechanism is slidably disposed on the upper side of the window frame.
[0016] The second objective of this invention is to provide a hardware system that includes the aforementioned hinge.
[0017] A hardware system applied to a tilt-and-turn window, comprising at least one tilt-and-turn window hinge.
[0018] The third objective of this invention is to provide a drifting inward tilt window that includes the aforementioned hardware system.
[0019] A tilt-and-turn window includes a window sash, a window frame, and the aforementioned hardware system.
[0020] Compared with the prior art, the beneficial effects of this utility model are:
[0021] The drifting inward tilting window hinge of this utility model has both the boss used to limit the connecting rod and the elastic limiting structure set on the base that is fixedly connected to the window sash. On the one hand, it is easy to assemble, and on the other hand, it can simplify the connecting rod structure. As in the solution of this utility model, only one connecting rod is needed to connect the sliding mechanism and the base respectively.
[0022] The boss of this utility model's drifting inward tilting window hinge effectively limits the maximum extension angle and minimum retraction angle of the connecting rod, thereby stably and reliably controlling the translational or inward tilting opening distance and the degree of locking and sealing between the window sash and the window frame. It also facilitates user positioning when the window sash is translating or tilting inward, improving the user experience. Simultaneously, the elastic limiting structure provides elastic restraint when the connecting rod is at its maximum extension angle and minimum retraction angle (i.e., the window sash's translational opening posture, translational locking posture, or inward tilting opening posture), allowing the connecting rod and window sash to remain stably in a certain posture, preventing accidental translation, and improving the stability of the window sash during sliding and the sealing performance when the window sash and window frame are locked.

[0044] To better understand the above-mentioned objectives, features, and advantages of this utility model, it will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. Many specific details are set forth in the following description to provide a thorough understanding of this utility model; the described embodiments are merely some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.
[0045] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.
[0046] See Figures 1-12 This embodiment discloses a drifting inward tilting window hinge, including a sliding mechanism 1, a connecting rod 2, and a base 3. The sliding mechanism 1 is slidably mounted on the window frame 6, the base 3 is fixedly connected to the window sash 7, one end of the connecting rod 2 is rotatably connected to the sliding mechanism 1, and the other end of the connecting rod 2 is rotatably connected to the base 3. In this embodiment, the sliding mechanism 1 can be equipped with pulleys or connected to other pulley components to achieve sliding on the window frame 6.
[0047] In this embodiment, for limiting the movement of connecting rod 2, a boss 4 and an elastic limiting structure 5 are provided on the base 3. The boss 4 protrudes from the base 3 and limits the maximum extension angle and minimum retraction angle of connecting rod 2 by preventing its rotation. When connecting rod 2 is at its maximum extension angle (see...), Figure 8 ), the window sash 7 is located outside the window frame 6, and the elastic limiting structure 5 prevents the connecting rod 2 from rotating in the direction of retracting the window frame 6 by an overcoming elastic force; when the connecting rod 2 is at its minimum extension angle (see Figure 7 The window sash 7 is located inside the window frame 6. The elastic limiting structure 5 prevents the connecting rod 2 from rotating out of the window frame 6 by an overcoming elastic force. In this embodiment, the maximum extension angle and the minimum retraction angle of the connecting rod 2 can be understood as the state of the connecting rod 2 after the window sash 7 has translated or tilted inward away from the window frame 6, and the state of the connecting rod 2 when the window sash 7 is locked inside the window frame 6.
[0048] Furthermore, the connecting rod 2 is provided with an extension limiting post 202 and a retraction limiting post 203, which extend towards one side of the base 3 and are located on both sides of the rotational connection point between the connecting rod 2 and the base 3. The boss 4 limits the maximum extension angle and the minimum retraction angle of the connecting rod 2 by blocking the extension limiting post 202 and the retraction limiting post 203. In this embodiment, the extension limiting post 202 and the retraction limiting post 203 are fixedly connected to the connecting rod 2, which can be achieved by riveting or other fixing methods.
[0049] As another implementation method, in addition to using a columnar structure to cooperate with the boss 4 to form a blocking and limiting effect, a protrusion or other structural form can also be set on the connecting rod 2, mainly based on the ability to form a blocking and limiting effect with the boss 4. The structural form can be flexibly changed and adjusted.
[0050] Furthermore, the boss 4 is located on the side of the base 3 near the window frame 6. The boss 4 has a first recess 401 and a second recess 402 on the side facing the connection between the connecting rod 2 and the base 3. The first recess 401 and the second recess 402 protrude from each other. The first recess 401 is used to adapt to the extension limiting post 202, and the second recess 402 is used to adapt to the retraction limiting post 203.
[0051] After the window sash 7 is completely moved horizontally or tilted inward out of the window frame 6, the connecting rod 2 is at its maximum extension angle. At this time, the extension limit post 202 is pressed against the first recess 401. The boss 4 blocks the extension limit post 202 at this position, restricting the connecting rod 2 from continuing to rotate in the extension direction. This allows the window sash 7 to continue to move away from the window frame 6 or tilt inward (which can be understood as moving or tilting inward), thereby improving the subsequent pushing and pulling stability of the window sash 7. Similarly, when the window sash 7 is completely moved into the window frame 6, the connecting rod 2 is at its minimum extension angle. At this time, the retraction limit post 203 is pressed against the second recess 402. The boss 4 blocks the retraction limit post 203 at this position, restricting the connecting rod 2 from continuing to rotate in the retraction direction. This allows the window sash 7 to continue to move into the window frame 6 or tilt inward (which can be understood as moving or tilting outward), thereby improving the locking accuracy between the window sash 7 and the window frame 6 and also helping to improve the sealing effect.
[0052] In this embodiment, the base 3 is further provided with a protruding fixing post 302, and a bushing 301 is provided on the fixing post 302; a fixing member 201 is provided at one end of the connecting rod 2 near the base 3, and the fixing member 201 is adapted to the bushing 301 to realize the rotatable connection between the connecting rod 2 and the base 3. Specifically, the fixing member 201 in this embodiment is fixed to the connecting rod 2 by riveting or other fixing methods. By assembling the fixing post 302 and bushing 301 on the base 3 with the fixing member 201 on the connecting rod 2, the structure is simple and it is convenient to realize the rotatability between the connecting rod 2 and the base 3. Moreover, this assembly method can leave a certain gap between the connecting rod 2 and the base 3, which makes it easier for the boss 4 to limit the maximum extension angle and minimum retraction angle of the connecting rod 2.
[0053] Of course, besides this rotatable connection, other rotatable connection methods in the prior art, such as riveting and bearing connection, can also be used between the connecting rod 2 and the base 3. The implementation method of the rotatable connection between the connecting rod 2 and the sliding mechanism 1 in this embodiment can also refer to the riveting and bearing connection methods in the prior art.
[0054] The elastic limiting structure 5 of this embodiment includes a rotating seat 501, an elastic element 502, and a limiting guide 503. One end of the rotating seat 501 is rotatably connected to the base 3. The limiting guide 503 is slidably disposed on the rotating seat 501. The elastic force of the elastic element 502 acts on the rotating seat 501 and the limiting guide 503. One end of the limiting guide 503 extends out of the rotating seat 501 and is rotatably connected to the connecting rod 2. When the connecting rod 2 is at its maximum extension angle or minimum retraction angle, the force exerted by the limiting guide 503 on the connecting rod 2 is located outside the rotational connection point between the connecting rod 2 and the base 3. In this embodiment, the elastic element 502 can be a spring.
[0055] Furthermore, an inner cavity can be provided on the rotating seat 501 in this embodiment, and the elastic element 502 is disposed in the inner cavity; the limiting guide 503 includes a first column 5031 and a second column 5032, the first column 5031 and the second column 5032 are perpendicular to each other; the elastic force of the elastic element 502 acts on the first column 5031, and the second column 5032 is rotatably connected to the connecting rod 2.
[0056] Furthermore, in this embodiment, the connecting rod 2 is provided with a fixing rod 204, the second column 5032 is hollow, and the fixing rod 204 is located on one side of the retractable limiting column 203. The fixing rod 204 is inserted through the hollow of the second column 5032 to achieve a rotatable connection between the limiting guide 503 and the connecting rod 2. Of course, the limiting guide 503 and the connecting rod 2 can also be rotatable by means of riveting, bearing connection, etc.
[0057] This embodiment employs an elastic limiting structure 5, which is simple in structure and effective in preventing the connecting rod 2 from being accidentally pulled out or pushed back. Specifically, the limiting guide 503 in this embodiment is rotatably connected to the connecting rod 2, so that the elastic limiting structure 5 exerts a force throughout the entire process of the window sash 7 being pulled out or pushed back into the window frame 6. This not only prevents accidental pulling out or pushing back, but also assists in pulling out or pushing back, demonstrating ingenious design and good effect. For example, when the window sash 7 is locked inside the window frame 6, that is, when the connecting rod 2 is at its minimum retraction angle, such as... Figure 7 As shown, at this time, the limiting guide 503 of the elastic limiting structure 5, under the action of the elastic element 502, exerts a force on the connecting rod 2 that can to a certain extent prevent the window sash 7 from being pulled out horizontally, that is, it can prevent the connecting rod 2 from rotating in the direction of pulling out the window sash 7. Of course, when it is necessary to pull out the window sash 7, the user only needs to overcome this elastic force to pull out the window sash 7, which can prevent accidental pulling out without affecting normal use. Moreover, under the force exerted by the elastic limiting structure 5 on the connecting rod 2, it can also ensure that the connecting rod 2 remains stable, thereby keeping the window sash 7 sealed to the window frame 6, which is beneficial to improving the sealing effect. Similarly, when the window sash 7 is outside the window frame 6, that is, when the connecting rod 2 is at its maximum extension angle, as Figure 8 As shown, at this time, the limiting guide 503 of the elastic limiting structure 5 exerts a force on the connecting rod 2 under the action of the elastic element 502, which can to a certain extent prevent the window sash 7 from being translated or pushed back. That is, it can prevent the connecting rod 2 from rotating in the direction of pushing the window sash 7 back. When it is necessary to translate or push back the window sash 7, the user's pushing force can overcome the force of the elastic limiting structure 5 on the connecting rod 2 and push the window sash 7 into the window frame 6. This effectively prevents the window sash 7 from accidentally translating or tilting back to the side of the window frame 6, which is conducive to improving the stability of the window sash 7 when it is used for side sliding or tilting inward, and avoids the window sash 7 from shaking.
[0058] Alternatively, the elastic limiting structure 5 in this embodiment can also be implemented without being connected to the connecting rod 2. A component with elastic extension and retraction is provided on the base 3 to block the connecting rod 2, which can also achieve the effect of elastic limiting to prevent accidental translation.
[0059] The tilt-and-turn window hinge of this embodiment can be applied to the upper pulley hinge of the tilt-and-turn window. In this case, the sliding mechanism 1 of this embodiment can be slidably set on the upper side of the window frame 6.
[0060] This embodiment also discloses a hardware system applied to a tilt-and-turn window, including at least one tilt-and-turn window hinge. This hardware system is similar to existing technology and generally includes hardware components such as a actuator and a handle to realize functions such as connecting the window sash 7 to the window frame 6, sliding the window sash 7, tilting the window sash 7 inwards, pushing and pulling the window sash 7, and locking.
[0061] This embodiment also discloses a drifting inward tilt-and-turn window, including a window sash 7, a window frame 6, and a hardware system.
[0062] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Therefore, any modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the scope of the technical solution of the present utility model.
