[0002] At present, the windows widely used in factories, venues, office buildings, teaching buildings, apartment buildings, as well as houses, commercial and residential buildings and other places on the market are mostly manually operated outward-sliding windows. They are composed of a pair of wind braces and a pair of friction hinges installed in the middle and upper parts of both sides of the window frame, and the handles at the bottom edge of the window sash and the push-link aluminum groove locking point components in the bottom edge groove. The hanging opening and closing and unlocking and locking mechanisms are completed by manual push-pull operations, which provide users with various experience.

[0003] With the increasing adoption of intelligent automation and remote control technologies, manual windows are becoming obsolete. Some windows now use electronically controlled, powered opening and closing mechanisms, as well as locking and unlocking. These are categorized into two types: exterior-mounted, typically using chain-type or electric telescopic actuators. These expose the mechanisms and wiring, making them unsightly, unsafe, and perceived as inferior. A small number of concealed-mounted systems utilize an electric actuator concealed on one side of the window frame for opening and closing, and an electric lock box concealed on the bottom edge of the sash for locking and unlocking. This concealed installation method offers both aesthetic appeal and safety, but it increases the number and complexity of mechanical components within the window, as well as the manufacturing and installation process.

The second torsion spring 23 is mounted on the unlocking plate pin 18, with one torque arm abutting against the unlocking plate T-shaped flange 111, and the other torque arm being adapted to abut against the bracket mounting portion of the adjacent boss side wall, thereby applying 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 support the outer limit port portion of the rotating groove 9, that is, lock the C-shaped groove end of the rotating groove 9 to maintain a straight and aligned spliced ​​state with the C-shaped groove of the oblique sliding groove 22. The forward rotation of the rotary groove unlocking plate 11 is clockwise in the embodiment, and the reverse rotation is counterclockwise.

[0057] In other possible implementations, such as Figure 3 As shown, a rotation slot limiting boss 83 is provided on the single arm of the bracket corresponding to the rotation slot 9, and an inclined limiting surface is provided on one end of the rotation slot limiting boss 83 close to the rotation slot 9. When the rotation slot 9 rotates clockwise, the rotation slot 9 is limited by the movement of the rotation slot 9, providing an angular stop for the rotation slot 9 to prevent excessive rotation, and can provide side support for the rotation slot 9.

[0058] The top surface of the rotating groove 9 is an inclined surface or an upwardly arched arc surface. When it is an inclined surface, such as Figure 4 As shown, it is tilted upward from left to right to prevent interference with the oblique sliding groove 22 during the rotation of the rotating groove 9.

[0059] The steps for using the window switch lock linkage mechanism provided in this embodiment are as follows:

[0060] The window closing and locking working actions of the mechanism are as follows: during the window closing process, the sliding member at the actuator end of the window opener first slides along the oblique sliding groove 22 to close the window. When it is near the window closing position, the sliding member enters the groove portion of the rotating groove 9, which will apply a clockwise rotating external force to the rotating groove 9 and continue to push the window sash to close. When the window sash is about to be closed, the unlocking piece of the rotating groove unlocking piece 11 hits the side of the window frame after hitting the tail end 114 and is pressed down. That is, the rotating groove unlocking piece 11 overcomes the elastic torsion force of the second torsion spring 23 and rotates clockwise, retracting the unlocking piece convex beak 113 that originally pressed against the upper end of the rotating groove 9, unlocking the side of the end of the rotating groove 9, and the sliding member fluctuates the rotating groove 9 of the rotating groove assembly, overcoming the torsion of the first torsion spring 20 The elastic torsion force applied by the force arm to the side surface of the lower end of the fan-shaped tooth portion drives the rotary groove tooth piece 10 to rotate with the rotary groove shaft column 84 as the selection axis (clockwise in the embodiment drawing). The tooth portion of the rotary groove assembly drives the rack 12 engaged with its tooth portion to slide downward, and the rack 12 drives the connecting rod 14 to press downward, and then drives the rocker arm 13 to rotate with the rocker arm bracket pin 17 as the rotation axis (counterclockwise in the embodiment drawing). The rocker push-pull convex head 132 at the convex head end of the rocker arm 13 pulls the bottom groove connecting rod 19 to slide (to the left in the embodiment drawing), driving the connecting rod locking point pin sleeve 24 close to the locking point block on the bottom edge of the window frame, and makes the connecting rod locking point pin sleeve 24 buckle with the locking point block to complete the window sash locking action.

[0061] The unlocking and window opening working actions are as follows: during the window opening process, the sliding push member at the actuator end of the window opener first moves the rotating groove 9 of the rotating groove assembly in the window opening direction, and with the assistance of the elastic torsion applied by the torque arm of the first torsion spring 20, which is originally in a compressed state, to the lower end side of its fan-shaped tooth portion, drives the rotating groove tooth piece 10 to rotate with the rotating groove shaft column 84 as the rotation axis (counterclockwise in the embodiment drawings), and the teeth of the rotating groove assembly drive the rack 12 engaged with its teeth to slide upward, and the rack 12 drives the connecting rod 14 to lift up, and then drives the rocker arm 13 to rotate with the rocker arm bracket pin 17 as the rotation axis (clockwise in the embodiment drawings), and the rocker arm push-pull convex head 132 at the convex head end of the rocker arm 13 passes through the bottom groove The clearance of the rocker arm push-pull hole 191 at one end of the connecting rod 19 is nested and connected, and the bottom groove connecting rod 19 with the clearance nested in the bottom groove of the side edge 2 of the window sash is pulled to slide (to the right in the embodiment figure), and the connecting rod locking point pin sleeve 24 is gradually disengaged from the locking point block on the bottom edge of the window frame. When the groove portion of the rotating groove 9 is rotated to be aligned with the oblique sliding groove 22, the window sash unlocking action is completed; at the same time, the unlocking piece of the rotating groove unlocking piece 11 hits the tail end 114 and gradually separates from the window frame, and rotates under the elastic torsion of the second torsion spring 23. The unlocking piece convex beak 113 will rotate into place after the groove portion of the rotating groove 9 is rotated to be aligned with the oblique sliding groove 22, and it will press against the side surface of the upper end of the rotating groove 9 to lock the side of the end of the rotating groove 9.

[0062] It should be additionally explained that if the sliding member at the actuator end of the window opener continues to push the window sash along the groove portion of the rotating groove 9 and enters the groove portion of the oblique sliding groove 22, the window sash continues to open to a larger angle range.

[0063] Through the above structure, a window switch lock linkage mechanism is provided, which consists of a connected bracket 8 and a rotating groove 9 component installed thereon, a rotating groove unlocking piece 11 and an unlocking piece pin 18, a rack 12 and a rack pin 16, a rocker arm 13 and a rocker arm bracket pin 17, a connecting rod 14 and a rack connecting rod pin 15, a first torsion spring 20 and a second torsion spring 23. It has a simple structure and a flat design. It is installed in a wrap-around manner on a corner of the window sash and is used in conjunction with a concealed window opener. When the window is about to be closed, pressing the lower rotating groove unlocking piece 11 can cause the rotating groove 9 component to rotate, and then the latter pushes the rack 12 to drive the connecting rod 14 to rotate the rocker arm 13 and then pull the bottom groove connecting rod 19 component to lock the window sash, that is, to achieve closing and locking the window. The reverse action of the rotating groove 9 component completes the unlocking and opening of the window. Compared with similar products of concealed electric windows on the market that use a window opener plus an electric lock box, the electric lock box is eliminated, the mechanism is simplified, and the manufacturing and installation links are saved.

[0064] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
