Description

Technical Field

[0001] The utility model belongs to the technical field of doors and windows, and is a control opening positioning seat with an anti-misoperation function and a push-pull opening type window with the control opening positioning seat. Background Art

[0002] There are many types of existing push-pull opening doors or windows, the most typical of which is the "push-pull opening door or window" with the publication number CN101881121A published by the Chinese Patent Office; this application is mainly aimed at further improving the "push-pull opening door or window". The "push-pull opening door or window" has the following main structure: Figure 1 It includes a frame 1 and a movable fan 2. The movable fan is assembled on the frame 1 through an upper sliding mechanism 3 and a lower sliding mechanism 4, and can be pushed and pulled away from the plane of the frame to open. The upper sliding mechanism 3 includes an upper sliding member assembled in an upper slideway on the frame, a front end (the end installed on the frame is the front end in the CN101881121A document, and the "first end" is used uniformly in this application for ease of understanding and distinction, and the corresponding end installed on the movable fan is the "second end"), an upper swing arm 32 hinged to the upper sliding member 31, and a swing arm seat 33 hinged to the second end of the upper swing arm 32, and the swing arm seat is fixedly installed on the top of the movable fan (specifically, it can be installed on the upper frame of the movable fan). An assembly groove is provided on the movable fan (specifically, it can be the movable fan frame of the movable fan), and an opening device is assembled in the assembly groove. The opening device provided on the movable fan has at least a plurality of lock pins, a pair of shaft pins and a push pin that can be operated to move synchronously. A positioning seat 18 of the upper swing arm is also installed on the top frame of the frame. The positioning seat is located below the upper sliding member 31 and the first end of the upper swing arm when the movable door is in the closed state, that is, when the upper swing arm is folded (when the movable door is in the closed state), the positioning seat is below the hinge point of the first end of the upper swing arm; a positioning block is provided at the lower part of the first end of the upper swing arm 32 and below the hinge point of the upper sliding member, and the positioning block cooperates with the above positioning seat to limit the first end of the upper swing arm from moving backward (the direction in which the movable door is allowed to move is forward). A movable blocking block is provided on the positioning seat 18, and the positioning block cooperates with the blocking block to block or allow the first end of the upper swing arm to continue to move backward along the upper slide with the upper sliding member; the blocking block is assembled on the positioning seat and can be controlled by the opening device, that is, the above-mentioned blocking block is moved (operated) by moving the pin, such as the blocking block can be operated to offset the vertical plane of the upper slide to allow the upper sliding member to move backward without restriction.

[0003] Through the above structural design, the "sliding door or window" has at least the following basic functions:

[0004] Function 1, "Locking" function: The movable window is in the closed state, that is, the plane of the movable sash is within the plane of the frame (i.e., the window frame); through the operation of the opening device, the locking pins on the movable sash are located within the locking seats of the frame to lock the movable sash within the frame. At this time, the movable sash has been pushed into the plane of the frame where it is located, and the first end of the upper swing arm is in front of the position of the blocking block; then operate the opening device to the initial position (the first gear, such as when the handle in the operating mechanism is facing down), the blocking block is operated by the handle mechanism and is toggled to be on the sliding route (corresponding to the upper sliding track) of the first end of the upper swing arm, and all the locking pins have entered the locking seats, and the movable sash is locked.

[0005] Function 2, "Parallel Opening" function: At this time, the plane of the movable sash is parallel to and separated from the plane of the frame, and there is a certain distance between the plane of the movable sash and the plane of the frame for ventilation inside and outside the room. When the opening device is operated to a certain position (the second gear, such as when the handle in the operating mechanism is horizontally inclined downward), the axle pins on both sides of the bottom of the movable sash frame are separated from the axle pin seats, and all the locking pins are separated from the locking pin seats, and the lower sliding mechanism is locked and cannot move, and the blocking block is still in the blocking position. Pull the movable sash forcefully to rotate the movable sash out of the plane of the frame. The plane of the movable sash is far from the position when it was locked and is parallel to the plane of the frame. However, at this time, because the lower sliding mechanism is locked, the movable sash cannot be pushed to move.

[0006] Function 3, "Translation" function: At this time, the plane of the movable sash is far from the position when it was locked; on the basis of the parallel opening function, the movable sash moves forward along the track to make the movable sash far from the position when it was locked. When the opening device is operated to another position (the third gear, such as when the handle in the operating mechanism is horizontal), in addition to the axle pins on both sides of the bottom of the movable sash frame being separated from the axle pin seats, all the locking pins are separated from the locking pin seats, and the lower sliding mechanism is unlocked (because it has a low relevance to the technical problem solved by this application, it will not be elaborated here. For its structure and working principle, please refer to the patent document CN101881121A). The blocking block is still in the blocking position. Pull the movable sash forcefully to rotate the movable sash out of the plane of the frame. The plane of the movable sash is far from the position when it was locked and is parallel to the plane of the frame. Push the movable sash forward to make the movable sash far from the position when it was locked.

[0007] Function 4, "inward tilt" function (inward tilting opening function): The movable sash rotates with its lower part as the pivot, and its upper part tilts inward so that its upper part is separated from the plane of the frame, that is, the plane of the movable sash is inclined to the plane of the frame, which is used for ventilation. When the opening device is operated to the upper limit (the fourth gear position, for example, when the handle in the operating mechanism is facing upward), the axle pins on both sides of the bottom of the movable sash frame are located within the axle pin seats, and the remaining locking pins on the movable sash are all unlocked, enabling the bottom of the movable sash to rotate around the axle pins by a small angle without detaching from the plane of the frame; at this time, the blocking block on the positioning seat 18 is shifted by the dial pin 68 of the actuating mechanism to offset the sliding route of the first end of the upper swing arm, and the positioning block below the upper swing arm can move along the upward sliding route; by forcefully opening the movable sash, it can force the movable sash to rotate around the axle pin 69 by a small angle, causing the upper part of the movable sash to offset from the plane of the frame to form an inward tilt opening.

[0008] The above-mentioned blocking block mainly functions to block the backward movement of the first end of the upper swing arm along with the upward sliding member. When implementing the "locking", "parallel opening", and "translation" functions, the blocking block prevents the first end of the upper swing arm from moving backward to ensure that the upper swing arm and the lower swing arm form a parallel mechanism, achieving the effects of labor-saving, smooth, and fast closing operation of the movable sash. When implementing the "inward tilt" function, it is necessary to shift the blocking block to offset the sliding route of the first end of the upper swing arm so that the first end of the upper swing arm can slide backward, ensuring that the upper part of the movable sash can tilt inward with the lower part as the rotating part.

[0009] In the "inward tilt" state of the movable sash, the blocking block has shifted from the sliding route. If the "translation" is directly performed through the opening device, since the upper part of the movable sash has separated from the plane of the frame, the blocking block cannot be reset by operating the opening device on the movable sash (in this state, the blocking block is always on the offset sliding route), but the "translation" of the movable sash can be completely performed; however, when the movable sash is closed again after translation, due to the offset of the blocking block from the sliding route, it does not block the first end of the upper swing arm, and cannot block the rotation of the upper swing arm with the first end hinge point as the rotation point, so the movable sash cannot be rotated into the plane of the frame in a parallel state, and thus cannot quickly, labor-savingly, and accurately close the movable sash. If excessive force is applied, it is easy to cause deformation and damage to the movable sash.

[0010] In actual use, it is often necessary to close the movable sash first in the "tilt-in" state, and then operate the opening device to perform the "translation" action. This operation process has the following defects: in the tilt-in state, there is a large gap between the upper part of the movable sash and the frame, the air flow is large, and the pressure is relatively large, resulting in inconsistent air pressure between the upper and lower parts of the movable sash, making it difficult and laborious to close the movable sash; for movable sashes with a large height, the operating handle is often located at the lower part of the movable sash, making it even more difficult to push the movable sash to close by the handle; at the same time, in the "tilt-in" state, it is impossible for the user to always follow this operation step - first close and then "translate", and it is easy to make mistakes - directly operate the opening device to "translate", which will cause the movable sash to deform and damage over time, reducing the service life of the window. Utility Model Content

[0011] The utility model mainly solves the technical problems that the movable sash is difficult to close, deformed and damaged due to failure to effectively limit the first end of the upper swing arm, and provides a positioning seat for controlling opening and a push-pull opening window with the positioning seat.

[0012] The controlled opening positioning seat and the push-pull opening window of the present application are realized through the following technical solutions.

[0013] The controlled opening positioning seat of the present application includes a main body, which is installed on a frame to realize the inward tilting function of the movable door; the upper part of the main body forms a sliding route; it also includes a blocking block, a rear shifting member and a front shifting member; the blocking block can be operably and movably assembled at the sliding route, and its movable range is from the sliding route to the offset sliding route; the rear shifting member can be movably equipped on the main body, and can be operably controlled to offset or reset the blocking block; the front shifting member can be movably assembled on the main body, and can be operably controlled to reset the blocking block.

[0014] Furthermore, the blocking block moves on a horizontal plane, and its starting position is located on a sliding route; the main body has a sliding groove, and the blocking block can be assembled in the sliding groove so as to be movable along the sliding groove.

[0015] Furthermore, the above-mentioned front shifter is rotatably assembled on the top of the main body around its middle part and is located in front of the blocking block; the rear end of the front shifter can always contact the blocking block within its allowed rotation range; the rotation of the front shifter has a first position corresponding to the initial position of the blocking block and a second position corresponding to the offset position of the blocking block; the front face of the front shifter is provided with an extrusion surface and a cutting surface in sequence facing the translation direction and both are arranged at the front part of the front shifter; the extrusion surface is located within the sliding route when in the second position, and is located outside the sliding route when in the first position; the cutting surface is located at the front front end of the front face of the front shifter, and when the front shifter is in the second position, the cutting inlet of the cutting surface is outside the sliding route.

[0016] Furthermore, the rear shifting member is a plate-like structure and can be assembled at the bottom of the main body so as to rotate horizontally around the middle part, and its front end is connected to the bottom of the blocking block; the blocking block is operated by the rear shifting member to reset or offset it; the front side of the rear shifting member has at least a rear touch zone at the rear and a front touch zone at the front, which are arranged in the translation direction, and the rear touch zone and the front touch zone operate the reset and offset of the blocking block accordingly.

[0017] The push-pull opening type window of the present application includes a frame and a movable sash, the movable sash is assembled on the frame by an upper sliding mechanism and a lower sliding mechanism, and can be pushed and pulled to open away from the plane of the frame; the upper sliding mechanism includes an upper sliding member assembled in an upper slideway on the frame, an upper swing arm hinged to the upper sliding member at a first end, and a swing arm seat hinged to the second end of the upper swing arm, the swing arm seat is fixedly installed on the top of the movable sash; the movable sash is equipped with an opening device, the opening device has at least a plurality of locking pins, a pair of shaft pins and a push pin that can be operated to move synchronously; it also includes the above-mentioned control opening positioning seat; the control opening positioning seat is installed on the top frame of the frame, and is located at the lower part of the upper sliding member and the first end of the upper swing arm when the movable sash is in a closed state, and is used to block or allow the first end of the upper swing arm to move backward.

[0018] Furthermore, the pin is located on the front side of the rear shifting member, and the rear shifting member is operated by the movement of the pin.

[0019] Furthermore, a positioning block is provided at the lower part of the first end of the upper swing arm and below the hinge point of the upper sliding member. The positioning block cooperates with the blocking block provided on the above-mentioned main body to limit the backward movement of the first end of the upper swing arm; when the positioning block moves forward, it operates the front shift member to rotate, so that the blocking block is reset to block the positioning block from moving backward thereafter.

[0020] The control opening positioning seat of the present application is provided with a front shifting member, which can be operated by moving the operating member forward to rotate the front shifting member to reset the blocking block, thereby effectively blocking the operating member that moves backward thereafter, positioning the operating member, and facilitating the closing of the movable fan associated with the operating member; the setting of the cutting surface is conducive to the smooth passage of the operating member or the first end of the upper swing arm without being affected by the position of the front shifting member; similarly, the setting of the extrusion surface is also conducive to the smooth passage of the operating member or the first end of the upper swing arm without being affected by the position of the front shifting member.

[0025] Figure 4 It is a partial assembly schematic diagram of the push-pull opening window of the present application. Detailed implementation manners

[0026] See Figure 2 and Figure 3The control opening positioning seat 100 of the present application includes a body 101, which is installed on the frame to realize the inward tilting function of the movable door. The control opening positioning seat 100 can be installed on the frame through the body 101, and is located below the sliding direction of the first end of the upper swing arm, which is used to limit the sliding of the first end of the upper swing arm with the upper sliding member. A sliding route 102 is formed on the upper part of the body, and the sliding route corresponds to the upper slide, which is used for the first end of the upper swing arm to slide along the upper slide of the frame; the sliding route can also be interpreted as a space allowing the first end of the upper swing arm to pass or slide. The control opening positioning seat of the present application also includes a blocking block 103, a rear shifting member 104 and a front shifting member 105. The blocking block 103 can be operably and movably assembled at the sliding route 102, and its movable range is from the sliding route to the offset sliding route, which is used to block or allow the first end of the upper swing arm to slide along the sliding route. When the blocking block is located on the sliding route, the first end of the upper swing arm is blocked from continuing to slide; when the blocking block deviates from the sliding route, the first end of the upper swing arm is allowed to continue to slide. For the sake of convenience, it is defined that when the blocking block is located on the sliding route, it is the "initial position", "reset" means returning from the "deviated position" to the "initial position", and "deviate" means that the blocking block moves away from the "initial position". The rear shifting member 104 can be movably equipped on the main body 101, and can be operated to control the displacement or reset of the blocking block; this operation can be achieved through an operating member such as a pin on the window (see document CN101881121A). When the operating member moves forward, the blocking block 103 can be driven to deviate through the rear shifting member 104, thereby allowing the upper swing arm to move backward to achieve the "inward tilt" function. The front shifter 105 can be movably mounted on the body 101, and can be operated to control the blocking block to reset so that the blocking block is located on the sliding path; this operation can be achieved through an operating member such as a positioning block on a window (see document CN101881121A), and when the operating member moves forward, the blocking block 103 can be driven to reset by the front shifter 105, thereby effectively blocking the subsequent backward movement. In actual use, the offset can be an offset on the horizontal plane, or an offset in the vertical direction or a vertical-like direction, such as the blocking block realizing its offset by retracting and extending in the vertical direction (the part used for the blocking function leaves the sliding path); therefore, the activity mode of the rear shifter 104 and the front shifter 105 can be rotation, or horizontal movement or vertical movement, etc.

[0027] See also Figure 2 and Figure 3, the described blocking block 103 moves on a horizontal plane, and its starting position is located on the sliding route 102. The main body 101 has a chute 106, and the blocking block 103 is assembled in the chute 106 so as to be movable along the chute, thereby limiting the moving distance or rotation angle of the blocking block by the length of the chute. At the same time, the initial position and offset position of the blocking block are determined by both ends of the chute. The blocking block can directly pass through the chute and is not associated with the chute; it can also be slidably installed on the side wall of the chute along the chute. The shape of the chute is consistent with the moving track of the blocking block, such as an arc chute, etc., to make the blocking block move smoothly.

[0028] See again Figure 2 , the described front toggle piece 105 is rotatably assembled around its middle part at the top of the main body 101 (the surface where the sliding route is located) and is located in front of the blocking block. The rear end of the front toggle piece 105 can always be in contact with the blocking block within its allowable rotation range, so as to operate the blocking block to reset when needed; the rotation of the front toggle piece 105 has a first position corresponding to the initial position of the blocking block and a second position corresponding to the offset position of the blocking block, that is, the rotation range of the front toggle piece is from the first position to the second position. Among them, the first position can be defined by the blocking block, and the second position can be defined by the structure of the main body, the front toggle piece itself or the cooperation structure between the two. On the front surface of the front toggle piece 105 (the side close to the movable fan is positive, that is, the direction towards the inward inversion of the movable fan is positive), there are successively arranged a pressing surface 107 and a cutting-in surface 108 along the translation direction, and both are arranged at the front part of the front toggle piece; the pressing surface 107 is located within the sliding route in the second position and just outside the sliding route in the first position. The setting of this pressing surface is beneficial for the first end of the operating piece or the upper swing arm to pass smoothly without being affected by the position of the front toggle piece; when the first end of the upper swing arm slides forward along the sliding route, the pressing surface 107 is pressed to operate the rotation of the front toggle piece 105, thereby operating and forcing the blocking block 103 to reset. The described cutting-in surface 108 is located at the front end of the front surface of the front toggle piece. When the front toggle piece is in the second position, the cut-in port of the cutting-in surface 108 is outside the sliding route; the setting of the cutting-in surface can force the front toggle piece to rotate when the first end of the upper swing arm passes, so as to prevent the front toggle piece from rotating under the action of an external force and blocking the sliding route; no matter what position the front toggle piece is in between the first position and the second position, it can make the first end of the upper swing arm pass smoothly, which is beneficial for the first end of the operating piece or the upper swing arm to pass smoothly without being affected by the position of the front toggle piece. In order to ensure the smoothness of the sliding route, therefore, the assembly point in the middle of the front toggle piece should be located outside the width of the sliding route; the settings of its cutting-in surface 108 and pressing surface 107 are also to facilitate the first end of the upper swing arm to slide along the sliding route, and at the same time operate the rotation of the front toggle piece through its sliding to further operate the reset or smooth sliding of the blocking block.

[0029] See again Figure 3The rear dial 104 is a plate-like structure and can be assembled at the bottom of the body 101 horizontally around the middle, and its front end is connected to the bottom of the blocking block 103; the blocking block 103 is operated by the rear dial 104 to reset or deflect; similarly, the rotation of the rear dial 104 has a first position corresponding to the initial position of the blocking block and a second position corresponding to the offset position of the blocking block, and the rear dial rotates between its first position and the second position. The front of the rear dial has at least a rear touch zone 109 located at the rear and a front touch zone 110 located at the front, which are arranged in the translation direction, and the rear touch zone and the front touch zone operate the reset and deflection of the blocking block correspondingly; when the operating member (such as the pin operated by the opening device in the prior art) parallel to the sliding route (in the same plane) and horizontally moving moves forward, the rear touch zone and the front touch zone are driven successively to rotate the rear dial from the first position to the second position, so that the blocking block moves from the initial position to the offset position, and the blocking block deflects the sliding route to realize the "inward tilt" function. This structure can enable the blocking block to be offset on the horizontal plane, such as by driving the rear touch zone and the front touch zone to force the rear toggle member to rotate to drive the blocking block to move along the slide slot 106, thereby achieving the reset and offset of the blocking block.

[0030] In order to ensure smooth operation, the rear touch zone and the front touch zone are both set in a circular arc transition on the front side of the rear toggle member, such as chamfering; the cutting surface and the extrusion surface are also set in a circular arc transition on the front side of the front toggle member.

[0031] See also Figure 4 The push-pull opening window of the present application comprises a frame 1 and a movable fan 2, wherein the movable fan is connected to the upper sliding mechanism 3 and the lower sliding mechanism (which can be combined with the prior art Figure 1 ) is mounted on the frame 1, and can be pushed and pulled away from the plane of the frame to open; the upper sliding mechanism 3 includes an upper sliding member 31 mounted in the upper slideway on the frame, an upper swing arm 32 whose first end is hinged to the upper sliding member 31, and a swing arm seat 33 hinged to the second end of the upper swing arm, and the swing arm seat is fixedly mounted on the top of the movable fan; the movable fan is equipped with an opening device 5, which has at least a plurality of lock pins, a pair of shaft pins and a push pin 6 that can be operated to move synchronously. The above structure is the same as the prior art, and no further explanation is given here. For details, please refer to the patent document with publication number CN101881121A.

[0032] The sliding window of the present application also includes the above-mentioned control opening positioning seat 100; the control opening positioning seat 100 is installed on the top frame of the frame, and is located below the upper sliding member 31 and the first end of the upper swing arm when the movable door is in the closed state, and is used to block or allow the first end of the upper swing arm to move backward, so as to better realize the closing and inward tilting functions of the movable door.

[0033] The described pin 6 is located on the front of the rear actuator, and the rear actuator is operated by the movement of the pin. When operating the opening device, it will drive the pin to move forward. By the movement of the pin, the rear trigger area and the front trigger area are driven successively, causing the rear actuator to rotate, thereby operating the blocking block connected to the rear actuator to reset or deflect. When the pin drives the rear trigger area (for example, when the opening device is in the first gear, the second gear, and the third gear, correspondingly, when the movable sash is in the state of function one, function two, and function three), by the rotation of the rear actuator, the blocking block is reset. At the same time, the first end of the upper swing arm is just in front of the blocking block, thereby preventing the first end of the upper swing arm from moving backward, and the above functions can be better realized. When the pin drives the front trigger area (for example, when the opening device is in the fourth gear, correspondingly, when the movable sash is in the state of function four), by the rotation of the rear actuator, the blocking block deflects, and the first end of the upper swing arm can smoothly move backward along the sliding route, and the "inverted inside" function can be better realized.

[0034] A positioning block 4 is provided below the first end of the upper swing arm 32 and below the hinge point of the upper sliding member. The positioning block cooperates with the blocking block provided on the above-mentioned body to limit the backward movement (the allowable movement direction of the movable sash is forward) of the first end of the upper swing arm. When the positioning block moves forward, it operates the front actuator to rotate, causing the blocking block to reset to block the positioning block that moves backward later. That is, when directly operating the opening device to perform "translation" in the "inverted inside" state, since the blocking block has been reset when the movable sash moves forward, it can effectively block the positioning block that moves backward later (when the movable sash returns from the translation opening to the corresponding window frame), so that the movable sash can be easily and labor-savingly closed. It can be seen that the positioning block in this application is different from the positioning block in the prior art. In addition to playing a guiding role in moving along the sliding route and a blocking role in contacting the blocking block, it also has the function of operating the rear actuator to rotate to reset the blocking block. Thus, a series of problems such as the movable sash being difficult to close and easily damaging the window (the movable sash and the frame) caused by directly "translating" in the "inverted inside" state are better solved.
