Technical Field
[0001] This utility model belongs to the field of door and window technology, specifically relating to a support rocker arm mechanism. Background Technology
[0002] Helding windows are prone to accidental closure during use, such as in strong winds or due to human error. Current technology typically addresses this by using spring clips or friction between hinges to limit the closure against external forces. However, such methods lack sufficient stability, and the risk of accidental closure remains even under excessive external force. Utility Model Content
[0003] In order to overcome the above-mentioned shortcomings of the prior art, the purpose of this utility model is to provide a support rocker arm mechanism, which can effectively support the window sash in the open state and help solve the problem of the window sash closing unexpectedly.
[0004] The technical solution adopted by this utility model to solve its technical problem is:
[0005] A rocker arm support mechanism includes a first tie rod, a second tie rod, and a base;
[0006] The base is fixed to the window sash, and the base is provided with a sliding groove extending along the length direction;
[0007] One end of the first pull rod is rotatably connected to a rotating component, which is slidably disposed in the slide groove. Under the drive of the first pull rod, the rotating component slides and rotates in the slide groove; the other end of the first pull rod is movably connected to the window frame.
[0008] The base has a sliding groove with a first blocking part for causing the rotating member to rotate and a second blocking part for restricting the rotating member from continuing to slide in the window closing direction. The first blocking part is located in front of the second blocking part in the window opening direction. When the rotating member is triggered to rotate by the first blocking part, it can be locked towards the second blocking part and can abut against the second blocking part to prevent the rotating member from continuing to move in the window closing direction.
[0009] In a preferred embodiment of this utility model, the slide groove is provided with a hollow groove extending along the length direction; the first pull rod passes through the hollow groove through a connector and is connected to the rotating component.
[0010] A preferred embodiment of this utility model further includes a slider;
[0011] The slider is slidably disposed in the groove, and the slider is rotatably connected to one end of the first pull rod. The rotating component is rotatably connected to the slider.
[0012] In a preferred embodiment of this utility model, two opposite sides of the rotating member are provided with open grooves;
[0013] The first blocking part includes a first protrusion disposed in the slide groove. The first protrusion has a first guide surface facing the rotating member and a first recess for avoiding the rotating member. When the rotating member slides to the first guide surface, the first guide surface and the recess on the rotating member cooperate with each other to cause the rotating member to rotate in a specified direction. The first protrusion is used to limit the rotating member from continuing to move in the opening direction.
[0014] The second blocking part includes a second protrusion protruding in the width direction. The second protrusion is disposed on one side wall of the slide groove and extends in the length direction. When the window sash is suspended, the end of the second protrusion near the first blocking part is embedded in the groove of the rotating member to prevent the rotating member from moving in the direction of closing the window. There are at least two abutting points between the second protrusion and the rotating member.
[0015] Preferably, the extended lines of the two sides of the groove of the rotating component intersect; the first guide surface forms an acute angle with the side wall of the slide groove.
[0016] Preferably, a third protrusion is provided on the sidewall of the groove opposite to the second protrusion, and the third protrusion protrudes along the width direction of the groove; the distance between the end of the third protrusion near the first blocking part and the first blocking part is greater than the distance between the end of the second protrusion near the first blocking part and the first blocking part, that is, the ends of the second protrusion and the third protrusion are staggered to form a rotational space for the rotating member to rotate and reset; the distance between the second protrusion and the third protrusion is greater than the width of the rotating member and less than the length of the rotating member, ensuring that the rotating member can pass through the passage between the second protrusion and the third protrusion with a width dimension and restricting the rotation of the rotating member.
[0017] Preferably, the slider is supported on the second protrusion and the third protrusion, and the slider is provided with a guide portion, which is embedded between the second protrusion and the third protrusion;
[0018] The rotating component and the guide portion are located on the same side of the slider.
[0019] Preferably, a first notch is provided on both sides of the slide groove, between the second protrusion and the first protrusion, and between the third protrusion and the first protrusion; the rotating component uses the first notch to complete the rotation action.
[0020] In a preferred embodiment of this utility model, the rotating component includes a rotating seat and a guide seat disposed on the rotating seat; the rotating seat is parallelogram-shaped, and the four sides of the guide seat are provided with guide concave corners, which are centrally symmetrical.
[0021] The first blocking part corresponds to the guide concave angle. When the rotating member slides to the first blocking part, the first blocking part and one side of the guide concave angle cooperate to guide the rotating member to rotate in a specified direction. When the first blocking part and the guide concave angle are pressed together, the rotating member cannot continue to rotate and cannot slide in the direction of opening the window.
[0022] When the rotating member is in a locked position toward the second blocking part, there are at least two contact points between the second blocking part and the rotating seat to prevent the rotating member from moving toward the closing window direction.
[0023] Preferably, the first blocking part includes a fourth protrusion, which is disposed on one side wall of the slide groove and protrudes outward, and the height of the fourth protrusion corresponds to that of the guide seat;
[0024] The second blocking part includes a fifth protrusion and a sixth protrusion. The fifth protrusion and the sixth protrusion are respectively disposed on the two side walls of the slide groove and both protrude in the width direction. The sixth protrusion and the fourth protrusion are located on the same side wall of the slide groove. The end of the sixth protrusion near the fourth protrusion is provided with a slope.
[0025] The slide has a second notch on each of the two side walls between the first blocking part and the second blocking part to avoid the rotating part; when the window sash is suspended, the two diagonal sharp corners of the rotating part extend into the second notches on the two side walls of the slide and abut against the ends of the fifth protrusion and the sixth protrusion respectively.
[0026] In a preferred embodiment of this utility model, two opposite sides of the rotating component are provided with V-shaped opening grooves, and two guide posts are provided on the side of the rotating component facing the bottom of the groove, with the two guide posts respectively located at two opposite corners.
[0027] The side wall of the slide is provided with a guide protrusion, which corresponds to the height of the guide post; the guide protrusion cooperates with the guide post to guide the rotation direction of the rotating component.
[0028] Preferably, the first blocking portion includes a seventh protrusion; the second blocking portion includes an eighth protrusion, the eighth protrusion being disposed on one side wall of the slide groove, the eighth protrusion protruding in the width direction and extending along the length direction of the base; the eighth protrusion and the guide protrusion are located on the same side wall of the slide groove, and a recessed area is provided between the guide protrusion and the eighth protrusion.
[0029] Compared with the prior art, the beneficial effects of this utility model are:
[0030] The supporting rocker arm mechanism of this utility model utilizes the sliding and rotation of a rotating component on a base, combined with the guidance of a first and second blocking part on the base, to achieve hovering control of the window sash, which helps prevent the window sash from being accidentally closed when open. Furthermore, during the window opening process, the window sash is first pushed open to its limit, causing the first pull rod to drive the rotating component to slide on the groove of the base. Under the influence of the first blocking part, the rotating component rotates, and at this point, it is in a locked position, waiting to cooperate with the second blocking part to form a locking position. Then, the window sash is pulled back, and the first pull rod drives the rotating component to move towards the closing direction (closer to the second blocking part). Finally, the rotating component and the second blocking part abut against each other, preventing the rotating component from moving further towards the closing direction, thus achieving the purpose of hovering the window sash and preventing accidental closure.
[0031] In this invention, the first and second blocking parts that cooperate with the rotating parts are both set on the base. Since the base is fixed to the window sash, it can maintain a fixed relative position and does not move with the hinges or other transmission components. This allows the first and second blocking parts on the base to maintain good reliability, and their stability and resistance to damage are outstanding. This is beneficial for providing more precise and reliable cooperation conditions to the rotating parts, resulting in significant improvements in window sash suspension locking positioning and service life.

[0075] 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.
[0076] 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.
[0077] Example 1
[0078] See Figures 1-7 This embodiment discloses a support rocker arm mechanism, including a first pull rod 2, a second pull rod 3, and a base 1. The base 1 is fixed to the window sash and has a sliding groove 101 extending along its length. One end of the first pull rod 2 is rotatably connected to a rotating component 4, which is slidably disposed in the sliding groove 101. Under the drive of the first pull rod 2, the rotating component 4 slides and rotates within the sliding groove 101.
[0079] The other end of the first pull rod 2 is movably connected to the window frame, as described in existing technology. For example, the other end of the first pull rod 2 is connected to a hinge assembly, which includes a first connecting rod 7 and a second connecting rod 8. A frame fixing plate 11 is also connected to the window frame. One end of the first connecting rod 7 is rotatably connected to the frame fixing plate 11, and the other end is rotatably connected to the first pull rod 2 and can slide. One end of the second connecting rod 8 is rotatably connected to the frame fixing plate 11 and can slide on it, while the other end is rotatably connected to the first pull rod 2. A hinge point is provided between the second connecting rod 8 and the first connecting rod 7. This embodiment only provides one possible way of movably connecting the first pull rod 2 to the window frame, but it is not limited to this method. The support rocker arm mechanism of this embodiment can be applied to various hinge products between window sashes and window frames.
[0080] Furthermore, in this embodiment, the base 1 has a first blocking part for causing the rotating member 4 to rotate and a second blocking part for restricting the rotating member 4 from continuing to slide in the window closing direction at the slide groove 101. In the window opening direction (the direction in which the rotating member 4 moves in the slide groove 101 when the window is opened), the first blocking part is located in front of the second blocking part. When the rotating member 4 is triggered to rotate by the first blocking part, it can be locked towards the second blocking part and can abut against the second blocking part to prevent the rotating member 4 from continuing to move in the window closing direction (the direction in which the rotating member 4 moves in the slide groove 101 when the window is closed).
[0081] To facilitate the engagement between the first pull rod 2 and the base 1, a perforated groove 102 extending along the length direction is provided at the slide groove 101 in this embodiment. The first pull rod 2 passes through the perforated groove 102 via a connector 6 and is then connected to the rotating component 4. In conjunction with the hinge structure between the window frame and the window sash, this embodiment provides a perforated groove 102 at the slide groove 101. The end of the first pull rod 2 can be located at the bottom of the base 1, and the end of the first pull rod 2 is rotatably connected to the rotating component 4 via a connector 6, which can be a rivet. Other embodiments in the prior art, such as a bushing fit, can also be used to achieve this rotatability. A washer 5 is also provided between the first pull rod 2 and the rotating component 4 in this embodiment.
[0082] Furthermore, in this embodiment, two opposite sides of the rotating member 4 are provided with open grooves 401. The first blocking part includes a first protrusion 103 disposed in the slide groove 101. The first protrusion 103 is provided with a first guide surface 105 facing the rotating member 4 and a first recess 104 for avoiding the rotating member 4. When the rotating member 4 slides to the first guide surface 105, the first guide surface 105 and the groove 401 on the rotating member 4 cooperate with each other to cause the rotating member 4 to rotate in a specified direction. The first protrusion 103 is used to limit the rotating member 4 from continuing to move in the window opening direction. The second blocking part includes a second protrusion 106 protruding in the width direction. The second protrusion 106 is disposed on one side wall of the slide groove 101 and extends in the length direction. In the window sash suspended state, the end of the second protrusion 106 near the first blocking part is embedded in the groove 401 of the rotating member 4 to prevent the rotating member 4 from moving in the window closing direction. There are at least two abutment points between the second protrusion 106 and the rotating member 4.
[0083] Furthermore, the extended lines of the two sides of the groove 401 of the rotating part 4 intersect, and are roughly V-shaped. The purpose of this arrangement is to better cooperate with the first blocking part and rotate smoothly under the prompting of the first blocking part; the first guide surface 105 and the side wall of the slide groove 101 form an acute angle.
[0084] In this embodiment, a third protrusion 107 is provided on the side wall of the slide groove 101 opposite to the second protrusion 106. The third protrusion 107 protrudes along the width direction of the slide groove 101. The distance between the end of the third protrusion 107 near the first blocking part and the first blocking part is greater than the distance between the end of the second protrusion 106 near the first blocking part and the first blocking part. That is, the ends of the second protrusion 106 and the third protrusion 107 are staggered to form a rotational space for the rotating member 4 to rotate and reset. The distance between the second protrusion 106 and the third protrusion 107 is greater than the width of the rotating member 4 and less than the length of the rotating member 4, ensuring that the rotating member 4 can pass through the passage between the second protrusion 106 and the third protrusion 107 with the width dimension and restricting the rotation of the rotating member 4.
[0085] During the window opening process, the first pull rod 2 drives the rotating component 4 to slide towards the first protrusion 103 (in the opening direction). When the sharp corner of the rotating component 4 contacts the first guide surface 105, the first guide surface 105 guides it and cooperates with the groove 401 to make the rotating component 4 rotate in the specified direction. Finally, the part between the first recess 104 and the first guide surface 105 is embedded in the groove 401 to restrict the rotating component 4, so that the rotating component 4 cannot continue to move in the opening direction, that is, it cannot continue to move to the left side of the figure. Subsequently, the operation in the closing direction causes the first pull rod 2 to drive the rotating component 4 away from the first protrusion 103 (that is, towards the second protrusion 106), so that the end of the second protrusion 106 is embedded in the groove 401 of the rotating component 4 and uses the two action points to block the rotating component 4 (this process will cause the rotating component 4 to continue to rotate in the specified direction by a certain angle), so that the rotating component 4 cannot continue to move in the closing direction, thus achieving the suspension of the window sash.
[0086] When the groove 401 of the rotating component 4 abuts against the end of the second protrusion 106, the window sash is in a suspended and locked state. When it is necessary to close the window sash, the window sash needs to be pushed outwards, so that the first pull rod 2 drives the rotating component 4 to move closer to the first protrusion 103 again. Under the guidance of the first guide surface 105 and the sharp corner of the rotating component 4, the rotating component 4 continues to rotate in the specified direction and abuts against the first protrusion 103, and can no longer slide and rotate. Then, the window sash is moved in the closing direction, and the first pull rod 2 drives the rotating component 4 to move away from the first protrusion 103 (towards the second protrusion 106) until the end of the second protrusion 106 touches the side end of the rotating component 4. The rotating component 4 continues to rotate using the rotation space and gradually rotates back to the closed state and enters the passage between the second protrusion 106 and the third protrusion 107, thus successfully completing the closing action. In this embodiment, there are parts on both sides of the first recess 104 for abutting against the rotating member 4 to ensure that the rotating member 4 can be restricted from continuing to slide, that is, to provide a limit angle restriction for the opening direction of the window sash.
[0087] On both sides of the slide groove 101, a first notch 108 is provided between the second protrusion 106 and the first protrusion 103, and between the third protrusion 107 and the first protrusion 103; the rotating component 4 uses the first notch 108 to complete the rotation. In this embodiment, in order to allow the rotating component 4 to have sufficient space to rotate in the slide groove 101, a first notch 108 is provided on both sides of the slide groove 101, between the second protrusion 106 and the first protrusion 103, and between the third protrusion 107 and the first protrusion 103, to avoid obstructing the rotating component 4 and allow the rotating component 4 to complete the rotation smoothly. The length and position of the first notch 108 on both sides of the slide groove 101 can be set according to the actual situation, and the specific requirements of the actual product and parts shall prevail.
[0088] For positioning the window sash when it is opened to its limit, in addition to using the positioning of the rotating part 4 and the first protrusion 103, the hollow groove 102 on the base 1 can also be used. That is, the length of the hollow groove 102 limits the sliding distance of the rotating part 4 on the slide groove 101. When the end of the first pull rod 2 drives the rotating part 4 to slide to the end of the hollow groove 102, the end of the first pull rod 2 can no longer move, so the rotating part 4 can no longer slide in the slide groove 101. When the rotating part 4 slides to its limit position, the first protrusion 103 drives its rotation.
[0089] Example 2
[0090] See Figures 8-13 The difference between this embodiment and Embodiment 1 is that:
[0091] In this embodiment, a slider 10 is rotatably connected to the end of the first pull rod 2. The slider 10 is slidably disposed in the slide groove 101, and the rotating component 4 is rotatably connected to the slider 10. Driven by the first pull rod 2, the slider 10 slides in the slide groove 101 of the base 1, and drives the rotating component 4 to slide together. When the rotating component 4 slides to the first or second blocking part, it cooperates with it to realize the rotation of the rotating component 4 and the mutual locking with the base 1, so as to achieve the purpose of the window sash being suspended and having reliable limiting. By setting the slider 10, the wear on the rotating component 4 is reduced. The slider 10 serves as the carrier for sliding, while the rotating component 4 can focus on cooperating with the first and second blocking parts on the slide groove 101, making the structure more reliable and stable, and also extending the service life of the components.
[0092] In this embodiment, the first pull rod 2 and the slider 10, as well as the slider 10 and the rotating part 4, are rotatably connected by a connector 6, which can be riveted together with rivets.
[0093] The slider 10 is supported on the second protrusion 106 and the third protrusion 107. A guide portion is provided on the slider 10, embedded between the second protrusion 106 and the third protrusion 107. The rotating member 4 and the guide portion are located on the same side of the slider 10. This design allows the second protrusion 106, acting as a second blocking portion, to abut and limit the rotating member 4, and also cooperates with the third protrusion 107 to guide the rotating member 4 and the slider 10 during sliding. It also allows the slider 10 to be supported on the guide portion. This innovative and effective structure, coupled with the fact that both the second and third protrusions 106 are located on the base 1, form an integral structure with the base 1, or can even be manufactured as a single unit, effectively improving the rotational guidance, locking, and positioning of the rotating member 4.
[0094] Furthermore, during the window closing action, the rotating component 4 needs to continue rotating at a certain angle to enter the passage between the second protrusion 106 and the third protrusion 107. In this embodiment, an angled corner 1071 is provided at the end of the third protrusion 107 to guide the rotating component 4 and allow it to smoothly enter the passage.
[0095] Example 3
[0096] See Figures 14-18 The difference between this embodiment and Embodiment 1 and / or Embodiment 2 is that:
[0097] In this embodiment, the rotating component 4 includes a rotating base 404 and a guide base 405 disposed on the rotating base 404. The rotating base 404 is parallelogram-shaped, and each of the four sides of the guide base 405 is provided with a guide concave angle 406, which are centrally symmetrical. A first blocking part corresponds to the guide concave angle 406. When the rotating component 4 slides to the first blocking part, the first blocking part cooperates with one side of the guide concave angle 406 to guide the rotating component 4 to rotate in a specified direction. When the first blocking part and the guide concave angle 406 are pressed together, the rotating component 4 cannot continue to rotate and cannot slide in the direction of opening the window. When the rotating component 4 is in a locked posture facing the second blocking part, there are at least two contact points between the second blocking part and the rotating base 404 to prevent the rotating component 4 from moving in the direction of closing the window.
[0098] Furthermore, the first blocking part includes a fourth protrusion 109, which is disposed on one side wall of the slide groove 101 and protrudes outwards. The height of the fourth protrusion 109 corresponds to that of the guide seat 405. The second blocking part includes a fifth protrusion 1010 and a sixth protrusion 1011, which are respectively disposed on both side walls of the slide groove 101 and protrude outwards along the width direction. The sixth protrusion 1011 and the fourth protrusion 109 are located on the same side wall of the slide groove 101. The end of the sixth protrusion 1011 near the fourth protrusion 109 is provided with a slope 10111. In this embodiment, the slope 10111 is provided at this location so that the rotating member 4 can be smoothly guided into the passage between the fifth protrusion 1010 and the sixth protrusion 1011. The slide 101 has a second notch 1016 on each of the two side walls between the first and second blocking parts to avoid the rotating part 4; when the window sash is suspended, the two diagonal sharp corners of the rotating part 4 extend into the second notch 1016 on the two side walls of the slide 101, and abut against the ends of the fifth protrusion 1010 and the sixth protrusion 1011, respectively.
[0099] In this embodiment, the guide concave angle 406 is an obtuse angle, and the two sides of the guide concave angle 406 are not equal, one being longer than the other. In this embodiment, the fourth protrusion 109 contacts the shorter side of the guide concave angle 406 to cause the rotating member 4 to rotate.
[0100] Example 4
[0101] See Figures 19-26 The difference between this embodiment and embodiment 3 is that:
[0102] Two opposite sides of the rotating component 4 are provided with V-shaped openings 402. Two guide posts 403 are provided on the side of the rotating component 4 facing the bottom of the slide 101, and the two guide posts 403 are respectively located at two opposite corners. A guide protrusion 1012 is provided on one side wall of the slide 101. The height of the guide protrusion 1012 corresponds to that of the guide post 403. That is, the guide protrusion 1012 is lower than the rotating component 4 so as not to affect the rotation of the rotating component 4, but the guide protrusion 1012 can correspond to and contact the guide post 403. The guide protrusion 1012 and the guide post 403 cooperate to guide the rotation direction of the rotating component 4.
[0103] Furthermore, the first blocking part includes a seventh protrusion 1013; the second blocking part includes an eighth protrusion 1014, the eighth protrusion 1014 is disposed on one side wall of the slide groove 101, the eighth protrusion 1014 protrudes in the width direction and extends along the length direction of the base 1; the eighth protrusion 1014 and the guide protrusion 1012 are located on the same side wall of the slide groove 101, and a recessed area 1015 is provided between the guide protrusion 1012 and the eighth protrusion 1014.
[0104] In this embodiment, the rotating component 4 is provided with a bushing 9, which is inserted in the middle of the rotating component 4. The bushing 9 is riveted to the connecting component 6 to achieve rotation.
[0105] See Figures 23-24 When the window is opened, the first pull rod 2 drives the rotating component 4 to slide on the slide groove 101, moving it towards the side closer to the seventh protrusion 1013. When the rotating component 4 slides to the guide protrusion 1012, combined with the unfolding action between the first pull rod 2 and the second pull rod 3 and the base 1, the guide protrusion 1012 contacts the guide post 403 on the rotating component 4, providing guidance for the subsequent rotation of the rotating component 4 and preventing incorrect rotation direction. Figure 12 As shown in diagram (b) above. When the window sash is pushed open further until it can no longer be opened, the rotating component 4 is stopped by the seventh protrusion 1013. There are at least two limiting points between the rotating component 4 and the seventh protrusion 1013 to restrict the movement of the rotating component 4. Subsequently, the window sash is pulled back, that is, the first pull rod 2 drives the rotating component 4 to move in the closing direction, so that there are at least two mutually abutting points between the opening groove 402 of the rotating component 4 and the eighth protrusion 1014, so that the eighth protrusion 1014 blocks the rotating component 4 from moving further in the closing direction, realizing the window sash is suspended and opened.
[0106] When closing the window, push the window sash open again, causing the first pull rod 2 to move the rotating part 4 back to the seventh protrusion 1013 and be blocked by the seventh protrusion 1013. At the same time, the rotating part 4 continues to rotate at a certain angle. Finally, pull the window sash back, and the first pull rod 2 will move the rotating part 4 in the direction of closing the window. With the cooperation of the recessed area 1015, the opening groove 402 of the rotating part 4, the guide protrusion 1012 and the guide post 403, it will rotate in the specified direction and slide into the corresponding position of the eighth protrusion 1014, thus completing the closing of the window sash.
[0107] 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.
