A tilt-and-turn window upper hinge 3 is provided above the window frame 2 and above the window sash 1, and an auxiliary pulley hinge 4 is provided between the two tilt-and-turn window upper hinges 3.

[0020] First Embodiment See Figure 2-8 The auxiliary pulley hinge includes a sliding assembly 10, a transmission arm assembly 20, and a fixed seat 30. The sliding assembly 10 is used to slide to the middle position above the window sash 1 of the window body. One end of the transmission arm is connected to the sliding assembly 10. The fixed seat 30 is used to connect to the middle position above the window sash 1 of the window body. The other end of the transmission arm assembly 20 is connected to the fixed seat 30. The fixed seat 30 is connected to a transmission locking member 40 for locking the transmission arm assembly 20. The fixed seat 30 includes a fixed plate 31 and a clamping member 32A. The clamping member 32A is disposed in the C-shaped groove 101 of the window sash 1. The fixed plate 31 is covered outside the C-shaped groove 101, and the fixed plate 31 and the clamping member 32A are clamped and fixed to the upper groove wall 1011 of the C-shaped groove 101.

[0021] The additional pulley hinge in this design is used on the tilt-and-turn window, positioned between the two existing hinges above the tilt-and-turn window to enhance load-bearing capacity and provide reinforcement. By setting the fixing plate 31 and the clamping member 32A on the inner and outer surfaces of the C-groove 101 respectively, the fixing seat 30 is positioned by clamping the C-groove 101, simplifying the mounting structure and making installation convenient.

[0022] In this embodiment, the transmission arm assembly 20 includes a primary swing arm 21, a secondary swing arm 22, and a secondary auxiliary swing arm 23. One end of the primary swing arm 21 is rotatably connected to the component 10, and the other end of the primary swing arm 21 is rotatably connected to one end of the secondary swing arm 22. One end of the secondary auxiliary swing arm 23 is slidably and rotatably connected to the secondary swing arm 22, and the other ends of the secondary swing arm 22 and the secondary auxiliary swing arm 23 are respectively rotatably connected to the fixed plate 31. The expansion and contraction between the primary swing arm 21 and the secondary swing arm 22 are used to realize the sliding opening or closing of the tilt-and-turn window. The opening between the secondary auxiliary swing arm 23 and the secondary swing arm 22 can further realize the tilt-and-turn state above the tilt-and-turn window.

[0023] Specifically, the secondary swing arm 22 is provided with a first locking member 24, and the secondary auxiliary swing arm 23 is provided with a sliding groove 231 along its length. One end of the first locking member 24 is rotatably connected to the secondary swing arm 22, and the other end of the first locking member 24 is slidably connected to the sliding groove 231. The transmission locking member 40 includes a transmission bar 41 and a second locking member 42. The transmission bar 41 is slidably connected to one side of the fixed plate 31.

The transmission bar 41 is used to drive the second locking member 42 to move to engage or disengage from the first locking member 24.

[0024] When the first locking member 24 engages with the second locking member 42, the secondary swing arm 22 and the secondary auxiliary swing arm 23 retract and lock, while the primary swing arm 21 and the secondary swing arm 22 can retract and expand to achieve locking or sliding of the tilt-and-turn window. When the first locking member 24 disengages from the second locking member 42, the secondary swing arm 22 and the secondary auxiliary swing arm 23 can expand and retract to achieve locking or tilt-and-turn of the window. Specifically, the first locking member 24 is a locking point, and the second locking member 42 is a locking seat; or, the first locking member 24 is a locking seat, and the second locking member 42 is a locking point.

[0025] In this embodiment, one side of the fixed plate 31 is provided with a slide rail 311 for sliding the transmission bar 41, and the other side of the fixed plate 31 is provided with a mounting position 312 protruding from the fixed plate 31. The mounting position 312 is used to connect the other end of the secondary swing arm 22 and the other end of the secondary auxiliary swing arm 23 respectively. The transmission bar 41 is slidably connected in the fixed plate 31 and does not need to be inserted into the C-shaped groove 101. The structure is simple and the installation is convenient. The protruding mounting position 312 can provide clearance for the first swing arm, the second swing arm, and the second auxiliary swing arm, which facilitates their retraction and simplifies the structure.

[0026] See Figure 6The sliding assembly 10 includes an upper sliding frame 11, a pulley block 12, a mounting nut block 13, and an anti-noise block 14. The pulley block 12 is rotatably connected to the upper sliding frame 11 for rolling connection with the window frame 2. The mounting nut block 13 is rotatably connected to the upper sliding frame 11 for limiting the upper sliding frame 11 to the inside of the window sash. The anti-noise block 14 abuts against the window sash to prevent the upper sliding frame 11 from contacting the window frame 2. The pulley block is fixed by inserting the mounting nut block 13 into the window sash profile and rotating it. The mounting nut block 13 abuts against the bottom wall of the window frame profile, the pulley block 12 abuts against the side wall of the window frame profile and rolls, and the anti-noise block 14 abuts against the top wall of the window frame profile to prevent the sliding assembly 10 from making noise during sliding.

[0027] In this embodiment, the fixing base 30 further includes a connecting fastener 33, which passes between the fixing plate 31 and the clamping member 32A, and is used to move the clamping member 32A closer to or away from the fixing plate 31. Specifically, the fastener is a bolt structure, and the clamping member 32A is provided with internal threads. The bolt structure connects the fixing plate 31 and the clamping member 32A through the threads.

[0028] In this embodiment, the clamping member 32A is a long strip clamping plate. The width of the long strip clamping plate is greater than the width of the C-shaped groove 101. The clamping member 32A is inserted into the C-shaped groove 101 from the side and is used to abut against the inner side of the upper groove wall 1011 of the C-shaped groove 101. After the long strip clamping plate is connected to the fixing plate 31, it is inserted into the groove along the side of the C-shaped groove 101. Then, by tightening the bolts, the long strip clamping plate and the fixing plate 31 are stably fixed on the window sash 1. The structure installed on the window sash 1 is simple and easy to operate.

[0029] Second Embodiment See further Figure 9 Unlike the first embodiment, in the second embodiment, the clamping member 32B is a clamping block. The length of the clamping block is greater than the width of the opening of the C-shaped groove 101, and the width of the clamping block is less than the width of the opening of the C-shaped groove 101. The clamping block is used to be placed from top to bottom in the C-shaped groove 101 along its width direction and rotated to be limited to the side wall of the C-shaped groove 101 and abutting against the inner side of the upper wall 1011 of the C-shaped groove 101 along its length direction. In use, the clamping block and fixing plate 31 are inserted directly from the outside to the inside of the C-shaped groove 101 in the window sash 1, without needing to pass through the groove from the side. During insertion, the width direction of the clamping block corresponds to the width direction of the C-shaped groove 101. After insertion, the clamping block is rotated so that its length direction corresponds to the width direction of the C-shaped groove 101. After the two ends of the clamping block in the length direction abut against the inner wall of the C-groove, the bolt structure is rotated further to bring the clamping block closer to the fixing plate 31, thus clamping and fixing the clamping block and fixing plate 31 onto the window sash 1. In this embodiment, the clamping block does not need to pass through a groove, resulting in a simpler structure and more convenient operation.
