Description

Technical Field

[0001] This invention relates to the field of door and window lock technology, and specifically to a window that uses a window opening and closing lock linkage mechanism. Background Technology

[0002] Currently, the windows widely used in factories, stadiums, office buildings, teaching buildings, apartment buildings, as well as residential buildings and commercial and residential buildings are mostly manually operated outward-opening windows. They consist of a pair of wind braces and a pair of friction hinges installed on the upper middle part of both sides of the window frame, and a handle on the bottom edge of the window sash and a push rod aluminum groove locking point assembly in the bottom edge groove. The window is opened and closed by manually pushing and pulling, providing users with a variety of experiences.

[0003] In an era where intelligent automation and remote control technologies are becoming increasingly widespread, manual windows are gradually becoming outdated. Some windows use electric controls for opening and closing, locking and unlocking. These fall into two categories: external and concealed. Externally mounted windows typically use chain-type or electric telescopic rod openers. The exposed mechanisms and wiring are unsightly, unsafe, and give a low-end impression. A smaller number use concealed designs, where an electric opener is concealed on one side of the window frame, and an electric lock box is concealed at the bottom of the window sash for locking and unlocking. This combination of opener and lock box achieves both aesthetic appeal and safety. However, it increases the complexity of the mechanisms and controls within the window frame, as well as the manufacturing and installation costs, leading to higher direct costs. Furthermore, the increased number of mechanisms naturally increases the likelihood of after-sales issues, further increasing after-sales costs and quality complaints. Summary of the Invention

[0004] Therefore, the technical problem to be solved by the present invention is to overcome the shortcomings of the concealed installation method that uses a combination of window opener and electric lock box, which increases the number and complexity of the mechanism arrangement and control mechanism on the window, as well as the manufacturing and installation, and increases the direct cost.

[0069] The rotary slot unlocking plate 11 is an approximately "7"-shaped structure. Its upper front corner has a T-shaped flange 111 for limiting the torque arm of the second torsion spring 23. Its front corner also has an unlocking beak 113 to abut or disengage from the corresponding end face of the rotary slot 9 to lock or unlock it. Near the center of its head is a second unlocking pin mounting hole 112 for the unlocking pin 18 to pass through and hinge with the first unlocking pin mounting hole 82 of the integrated bracket 8. Its lower end is a long rod or strip structure, with the unlocking plate pressing against the tail end 114 at the end. Together with the second torsion spring 23, it acts as the automatic unlocking mechanism for the rotary slot assembly, pressing against the switch handle. The second torsion spring 23 is fitted onto the unlocking pin 18, and its torque arm presses against the rotary slot unlocking plate 11. On the T-shaped flange 111 of the unlocking plate, another torque arm presses on the adjacent boss side wall of the integrated bracket 8 to apply a rotational elastic torque to the unlocking plate, so that the unlocking plate protrusion 113 of the rotary groove unlocking plate 11 can always automatically abut against the outer limit port of the rotary groove 9, that is, lock the C-shaped groove end of the rotary groove 9 to maintain a straight alignment and splicing state with the C-shaped groove of the oblique sliding push groove 22; the integrated bracket 8 carries the above-mentioned structural components installed on it to form a set of component mechanisms, which are fastened to the cross-section T-shaped groove on the side of the window sash through its V-shaped mounting groove and locking point pointed screw 25, or directly fastened to the side of the window sash through screws; the oblique sliding push groove 22 is fixed on the side of the window sash and maintains a straight alignment and splicing state with the outer limit port of the rotary groove 9 in the elastic reset state;

[0070] The bottom groove connecting rod 19, which is used to lock and unlock the window sash, consists of the bottom groove connecting rod 19 and the connecting rod locking pin sleeve 24 riveted to it. One end of the bottom groove connecting rod 19 is provided with a rocker arm push-pull hole 191 for interlocking with the rocker arm push-pull protrusion 132 of the rocker arm 13. The middle part is provided with a connecting rod middle strip hole 193 for allowing the handle to move. One or both ends of the connecting rod middle strip hole 193 are provided with handle spring hanging points 192. In the window sash assembly structure, the bottom groove connecting rod 19 is nested in the bottom groove of the bottom side 1 of the window sash, and is pushed and pulled by the rocker arm push-pull protrusion 132 of the rocker arm 13 in this bottom groove to perform the window sash locking or unlocking stroke movement.

[0071] The beneficial effects of this invention are: it provides a window with a window opening and locking linkage mechanism, consisting of a window body, a window opener 28, a sliding rocker assembly, a handle mechanism, a bottom groove connecting rod 19, and a window opening and locking linkage mechanism. The window opening and locking linkage mechanism has a simple structure and a flat design, and is installed in a wraparound manner on one corner of the window sash. It works in conjunction with a set of concealed window openers 28 and sliding rocker assemblies. When the window is about to close, pressing the lower rotary groove unlocking plate 11 will cause the rotary groove assembly to rotate, which in turn pushes the rack 12 to drive the connecting rod 14 to rotate the rocker arm 13, which in turn pulls the bottom groove connecting rod 19 to lock the window sash. The window opener 28 moves the rotary groove assembly in the opening direction to unlock the window sash. When the rotary groove assembly is completely reversed and returned to its original position, the window opener 28 continues to move in the opening direction to enter the opening action. Compared with similar products on the market that use a window opener 28 and an electric lock box, this invention simplifies the mechanism, manufacturing and installation links and costs, and reduces the number of after-sales problems.

[0072] The window opener 28 of this invention operates as follows when closing and locking the window: The window opener 28 drives the sliding pusher 31 at the tail end of the sliding pusher assembly to pull the oblique sliding groove 22 to close the window. When the window is close to the end, the sliding pusher 31 enters the groove of the rotating groove 9 and continues to push the window sash to close. When the window sash is about to close completely, the locking plate protrusion 113 at the tail end of the long arm of the rotating groove locking plate 11 touches the side of the window frame and is pressed down, that is, the rotating groove locking plate 11 overcomes the second torsion. The elastic torque of spring 23 disengages the unlocking plate protrusion 113 that was originally pressing against the upper end of the rotating groove 9, thus unlocking the side of the rotating groove 9. The rotating groove 9 is then actuated, overcoming the elastic torque applied to the lower end of its fan-shaped teeth by the torque arm of the first torsion spring 20, and rotating with the rotating groove toothed plate 10 about the rotating groove shaft column 84 on the integrated bracket 8 as the selection axis (clockwise in the attached drawings of the embodiment). The teeth of the rotating groove assembly drive the teeth of the rotating groove assembly to rotate with the teeth of the rotating groove assembly. The meshing rack 12 slides downwards, which in turn drives the connecting rod 14, one end of which is hinged to the pin hole 123 of the lower rack connecting rod pin mounting hole, to press down. The rocker arm connecting rod pin mounting hole 131 at one end of the V-shaped component rocker arm 13 is hinged to the pin hole at the lower end of the connecting rod 14, which in turn drives the rocker arm 13 to rotate around the rocker arm bracket pin 17 riveted to its V-shaped bottom, with the rocker arm bracket pin 17 mounting hole at the bottom of the long side wall 88 of the integrated bracket 8 serving as the hinge support hole. When rotation occurs (counterclockwise in the attached diagram of the embodiment), the rocker push-pull protrusion 132 at the protrusion end of the rocker arm 13 is connected to the rocker push-pull hole 191 at one end of the bottom groove connecting rod 19 through the gap, and pulls the bottom groove connecting rod 19, which is nested in the bottom groove on the side of the window sash, to slide (to the left in the attached diagram of the embodiment). Then, the window sash is locked by the connecting rod locking pin sleeve 24 riveted to the bottom groove connecting rod 19 and the locking block 33 on the bottom edge of the window frame.

[0073] The window opener 28 of this invention operates as follows: During the window opening process, the window opener 28 drives the sliding pusher 31 at the tail end of the sliding rocker assembly to first move the rotating groove 9 in the opening direction. With the assistance of the elastic torque applied by the torque arm of the first torsion spring 20, which was originally in a compressed state, to the lower side of its fan-shaped teeth, the rotating groove toothed piece 10 rotates around the rotating groove shaft column 84 on the integrated bracket 8 as the selection axis (counterclockwise in the attached drawings of the embodiment). The teeth of the rotary groove assembly drive the rack 12, which meshes with its teeth, to slide upward. The rack 12 then drives the connecting rod 14, one end of which is hinged to the pin hole 123 of the lower rack connecting rod, to lift upward. The rocker arm connecting rod pin hole 131 at one end of the V-shaped component rocker arm 13 is hinged to the pin hole at the lower end of the connecting rod 14, which in turn drives the rocker arm 13 to rotate around the rocker arm bracket pin 17 riveted to its V-shaped bottom, with the rocker arm support at the bottom of the long side wall 88 of the bracket of the integrated bracket 8 as the rotation axis. The mounting hole of the bracket pin 17 rotates (clockwise in the attached drawing of the embodiment). The rocker arm push-pull protrusion 132 at the protruding end of the rocker arm 13 is connected to the rocker arm push-pull hole 191 at one end of the bottom groove connecting rod 19 through a gap, which pulls the bottom groove connecting rod 19, which is nested in the bottom groove of the window sash side, to slide (to the right in the attached drawing of the embodiment). Then, the connecting rod locking pin sleeve 24 riveted to the bottom groove connecting rod 19 is connected to the locking block 33 on the bottom edge of the window frame. When the rotating groove 9 rotates to align with the oblique sliding groove 22, the window sash unlocking action is completed. Simultaneously, the unlocking protrusion 113 of the rotating groove unlocking plate 11 gradually disengages from the window frame and rotates under the elastic torque of the second torsion spring 23. After the rotating groove 9 rotates to align with the oblique sliding groove 22, the unlocking protrusion 113 rotates back into place and rests against the side surface of the upper end of the rotating groove 9, thus locking the side of the rotating groove 9 end. If the swing arm sliding member 31 at the actuator end of the window opener 28 continues to push the window sash along the groove of the rotating groove 9 and into the groove of the oblique sliding groove 22, the window sash continues to open to a larger angle.

[0074] The window closing and locking operation of the handle mechanism of the present invention is as follows: After the window opener 28 completes the window opening action, its output shaft stops at a certain set window opening angle. Simply grasp the handle 36 and push it outward to release the locking clutch of the window opener 28 and put it into manual operation mode. In this mode, the output shaft end of the window opener 28, that is, the swing arm assembly, enters a bidirectional free deflection state. Then, by gently pulling the handle 36 in the window closing direction, the window can be closed freely.

[0075] According to the example attached Figures 1-3The arrangement direction and position are shown: When the handle mechanism is selected to close the window, pull the handle 36 to the left, that is, turn it clockwise by an angle. The handle lever 38 at the bottom of the handle 36 will drive the handle drive spring 39 attached to it, which in turn will drive the bottom groove connecting rod 19 to move to the left. During this action, the bottom groove connecting rod 19 transmits through the multiple connections from the rocker arm 13, connecting rod 14, rack 12, and then to the rotating groove assembly. This pushes the rotating groove assembly to overcome the elastic torque of the first torsion spring 20 and rotate. When the rotating groove assembly and the rocker arm assembly rotate to the position, that is, when the handle 36 is deflected to the position, the connecting rod locking pin 24 on the bottom groove connecting rod 19 will engage with the locking block 33 on the bottom edge of the window frame, thus completing the window sash locking action. When the handle 36 is moved to the bottom towards the lock window, the elastic tension applied by the handle-driven spring 39 to the bottom groove link 19 is greater than the resistance transmitted by the first torsion spring 20 to the bottom groove link 19 through the mechanism, and the handle 36 itself has elastic damping position self-locking.

[0076] The unlocking and opening operations of the handle mechanism of this invention are as follows: After the window opener 28 completes the window closing action, its output shaft stops at the fully closed angle. The sealing and sound-insulating soft rubber strip installed in the peripheral grooves on the window sash and window frame provides pre-tightening force for the engagement of the window sash and window frame, that is, the locking pin sleeve 24 of the connecting rod and the locking point block 33 on the bottom edge of the window frame. Simply grasp the handle 36 and push it outward to release the locking clutch of the window opener 28 and put it into manual operation mode. In this mode, the output shaft end of the window opener 28, that is, the swing rod assembly, enters a free deflection state. Then, by gently pushing the handle 36 in the window opening direction, the window can be opened freely.

[0077] According to the example attached Figures 1-3 The arrangement direction and position are as follows: When selecting the handle mechanism to open the window, pull the handle 36 to the right, that is, turn it counterclockwise by an angle. This will cause the handle lever plate 38 at the bottom of the handle 36 to drive the handle drive spring 39, which in turn drives the bottom groove connecting rod 19 to move to the left. During this action, the bottom groove connecting rod 19 is transmitted through the multiple connections from the rocker arm 13, connecting rod 14, rack 12, and then to the rotating groove assembly, causing the rotating groove assembly to rotate. During this process, the elastic torque of the first torsion spring 20 is transmitted through these multiple connections to the connecting rod locking pin 24 on the bottom groove connecting rod 19, which disengages from the locking point block 33 on the bottom edge of the window frame. When the rotating groove assembly rotates to the position with the swing rod assembly, that is, when the handle 36 is deflected to the position, the connecting rod locking pin 24 on the bottom groove connecting rod 19 and the locking point block 33 on the bottom edge of the window frame are completely disengaged, thus completing the window sash locking action. Grasp the handle 36 and push it outward in the direction of opening the window. The sliding push part 31 of the swing arm assembly at the end will enter the groove of the push groove from the groove of the rotating groove 9. The window can be supported by the additional wind brace when it stops at the middle angle, or the window opener 28 can be activated to provide angle position support by the non-unlocked state of the window opening clutch.

[0078] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
