Description

Technical Field

[0001] The present invention relates to the technical field of door and window structures, and in particular to a double inward-opening window with a screen window hinge that opens at 90 degrees. Background Art

[0002] Existing door and window systems are primarily divided into casement windows and sliding windows. Casement windows are widely used in architectural decoration due to their large opening area, good ventilation, excellent sealing, sound insulation, thermal insulation, and anti-seepage properties. Casement windows are categorized by their opening method as either inward-opening or outward-opening. Inward-opening windows offer the advantage of convenient window cleaning, while outward-opening windows offer the advantage of taking up less space when open, but the disadvantage is a limited field of view. Inward-opening windows are often used to maximize visibility.

[0003] Screen fans are divided into invisible screen fans and non-invisible screen fans. Invisible screen fans are widely used because the screen fan hinge connecting the screen fan to the window frame is hidden at the connection point of the screen fan and the window frame when it is closed. The screen fan hinge is generally installed at the corner of the window frame. Therefore, aluminum profile window frames are widely used to have installation slots reserved in the corresponding parts as the fixing part of the screen fan hinge. The screen fan hinge is specially used to control the opening and closing of the screen fan and the window frame. Generally, when it is open, an opening and closing angle is formed between the screen fan and the window frame.

[0004] However, existing double-leaf inward-opening windows generally have window sashes and screen sashes arranged in sequence from the inside to the outside. Since the window sashes and screen sashes are fixed on the same side of the window frame, when the window sashes are opened, the screen sashes are difficult to fully open inward due to the thickness of the window sashes. The maximum opening and closing angle of the screen sashes is about 60°, which affects the user experience. Summary of the Invention

[0074] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this invention pertains. The terms used herein in the specification of the present invention are for the purpose of describing specific embodiments only and are not intended to limit the present invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0075] The "first" and "second" in the present invention do not represent specific quantities and orders, but are only used to distinguish names.

[0076] On the one hand, if Figure 1 and Figure 2 、 Figure 3 As shown, a screen window hinge in one embodiment of the present invention includes a mounting base 1, a mounting base plate 2, a first connecting rod 3 and a second connecting rod 4; the mounting base plate 2 is provided with a mounting hinge position 21, a sliding long slot 22 and a fixed mounting unit 23, the first connecting rod 3 is provided with a sliding end 31, a hinge portion 32 and a mounting portion 33, the sliding end 31 is slidably connected to the sliding long slot 22, and the mounting portion 33 is used to mount a screen window; the second connecting rod 4 is provided with a hinge end 41 hinged to the mounting hinge position 21, and a hinge end 41 hinged to the hinge portion 32. Connecting end 42; the mounting base 1 is provided with a mounting outer edge 11 for mounting on the window frame, and a mounting groove 12 for mounting the mounting base plate 2, and the mounting surface of the mounting outer edge 11 is perpendicularly arranged to the mounting surface of the mounting groove 12; the fixed mounting unit 23 includes a rotating member 231 and a rotating block 232, the rotating member 231 is provided with a rotating shaft portion rotatably connected to the mounting base 1, a clamping portion connected to the rotating block 232, and a rotating input portion, and the rotating block 232 is adapted to the mounting groove 12.

[0077] The above-mentioned screen window hinge is achieved by fixing the mounting base 1 of the hinge on the window frame and installing the screen fan on the mounting portion 33. When the screen fan is swung toward the room, the sliding end 31 of the first connecting rod 3 is slidably connected on the sliding long groove 22. The maximum opening angle of the screen fan relative to the mounting plane of the window frame can reach 90°, which reduces the space occupied by the screen fan, facilitates a wider field of vision, and improves the user experience.

[0078] At the same time, because existing screen window hinges are usually installed on the flat surface of the window frame, the flat surface of the window frame is soaked in rainwater, and the hinges are easily corroded and rusted. By installing the outer mounting edge 11 of the mounting base 1 on the flat surface of the window frame, the mounting base 2 is kept at a certain distance from the flat surface of the window frame when rainwater is present, and the hinges are less likely to corrode and rust, and have a longer service life.

[0079] In one embodiment, the sliding end 31 is slidably connected to the sliding slot 22 via a connecting structure 5. The connecting structure 5 includes a stopper shaft head 51 rotatably connected to the sliding end 31 and a stopper groove 52 disposed within the sliding slot 22. The stopper shaft head 51 includes a connecting shaft extending through the sliding slot 22 and a stopper shoulder adapted to the width of the stopper groove 52. This reduces the thickness of the hinge through the connecting structure 5, facilitating reduced installation dimensions and ensuring a wide field of view from the inner frame of the double-sash inward-opening window.

[0080] In one embodiment, the first connecting rod 3 includes a connecting rod body 301 and a mounting plate 302 disposed on the connecting rod body 301. The mounting plate 302 is an L-shaped bent plate, comprising a horizontal plate and a vertical plate. The mounting portion 33 includes a connecting portion disposed on the vertical plate and a top portion disposed on the horizontal plate. By separating the first connecting rod 3 into the connected connecting rod body 301 and the mounting plate 302, the structural strength of the first connecting rod 3 is enhanced. Furthermore, the different structures of the connecting rod body 301 and the mounting plate 302 reduce the overall processing difficulty of the first connecting rod 3, thereby reducing production costs.

[0081] On the other hand, Figure 4 and Figure 5 As shown, a double inward-opening window in one embodiment of the present invention includes a window frame 6, a window sash 7 and a screen fan 8; the window frame 6 is provided with a first frame body 61 and a second frame body 62 from the inside to the outside, and the inner frame space of the second frame body 62 is less than or equal to the inner frame space of the first frame body 61; both ends of the window sash 7 in the vertical direction are mounted on the first frame body 61 through a first hinge; both ends of the screen fan 8 in the vertical direction are mounted on the second frame body 62 through a screen window hinge.

[0082] In one embodiment, the second frame 62 is provided with a mounting edge groove adapted to fit within the mounting outer edge 11. The mounting base 1 is provided with a mounting and fixing unit 13 comprising a rotating protrusion with a top projection. The mounting base 1 has a rectangular outer profile, and the top projection and the mounting outer edge 11 are disposed at opposite corners of the rectangle. Thus, the diagonally disposed top projection and the mounting outer edge 11 enable the mounting base 1 to be stably mounted on the second frame 62.

[0083] like Figure 6 and Figure 7As shown, the screen fan 8 is provided with sliding grooves 81 at both ends in the vertical direction, and limiting grooves 82 are extended on both sides of the bottom of the sliding groove 81. One end of the sliding groove 81 and the limiting groove 82 extends out of the screen fan 8, and the connecting rod body 301 and the mounting plate 302 are both slidably installed in the sliding groove 81, and the two sides of the mounting plate 302 are clamped in the limiting groove 82, thereby completing the preliminary connection between the screen fan 8 and the screen window hinge; a clamping block 303 is integrally formed at one end of the mounting plate 302, and the mounting part 33 is arranged at the other end of the mounting plate 302, and clamping grooves 304 are provided on both sides of the clamping block 303; the screen fan 8 is fixedly installed with a connecting plate 83 in the sliding groove 81, and a pair of elastic buckles 84 are elastically provided at one end of the connecting plate 83, and the two elastic buckles 84 are arranged opposite to each other, and the two elastic buckles 84 are respectively buckled in the two clamping grooves 304.

[0084] When installing the screen fan 8, first align the sliding grooves 81 at both ends of the screen fan 8 in the vertical direction with the block 303 of the screen window hinge, and then slide the connecting rod body 301 and the mounting plate 302 into the sliding groove 81 until the mounting portion 33 abuts against the side of the screen fan 8, and at the same time, the elastic buckle 84 is buckled in the positioning groove 304, and finally, the mounting portion 33 is fixed to the screen fan 8 by bolts, so that the detachable connection between the screen fan 8 and the screen window hinge can be achieved; in the above-mentioned installation method, the mounting plate 302 is connected to the connecting plate 83 by sliding in the sliding groove 81, that is, the connection between the mounting plate 302 and the screen fan 8 is completed. Compared with the connection method of tightening the bolts from bottom to top, the installation is convenient and quick.

[0085] Further, such as Figure 8 and Figure 9 As shown, a bottom magnetic component 65 is fixedly installed at the bottom of the second frame 62 and at one end away from the screen window hinge, and a top magnetic component 85 is fixedly installed at the bottom of the screen fan 8 and at one end away from the screen window hinge. The bottom magnetic component 65 includes a first mounting shell 651, a first locking shell 652 and a south pole magnet 653. The first mounting shell 651 is fixedly installed on the second frame 62 by means of bolts. The bottom end of the first mounting shell 651 is open in the vertical direction and a first inclined surface 654 is provided on the top; the south pole magnet 653 is installed in the first mounting shell 651 and abuts against the top near the first mounting shell 651; the first locking shell 652 is clamped in the first mounting shell 651 and abuts against the south pole magnet 653, so that the south pole magnet 653 can be stabilized in the first locking shell 652.

[0086] The top magnetic member 85 comprises a second mounting shell 851, a second clamping shell 852 and a north pole magnet 853, and the connection mode among the second mounting shell 851, the second clamping shell 852 and the north pole magnet 853 is the same as the connection mode among the first mounting shell 651, the first clamping shell 652 and the south pole magnet 653; the difference is that the first mounting shell 651 is clamped in the sliding groove 81, and the side of the first mounting shell 651 facing downward is provided with a second inclined surface 854 matched with the first inclined surface 654.

[0087] When the top magnetic member 85 is close to the bottom magnetic member 65, the south pole magnet 653 and the north pole magnet 853 attract each other, so that the top magnetic member 85 and the bottom magnetic member 65 abut against each other, the screen fan 8 is in a stable closed state, and the screen fan 8 can be lifted away from the screen window hinge, preventing the screen fan 8 from sinking and being inconvenient to open and close.

[0088] As shown in Figure 10 and Figure 11 、 Figure 12 In one embodiment, the linkage component 9 further comprises a turn lock assembly 91 for linkage of the screen fan 8 and the window fan 7, the turn lock assembly 91 comprises a turn lock piece 911 arranged on the window fan 7, the turn lock piece 911 is provided with a locking part and an input part arranged on the surface of the window fan 7, and the screen fan 8 is provided with a rotating clamping groove, and the rotating clamping groove is provided with a special-shaped hole matched with the locking part. In this way, after the locking part is inserted into the special-shaped hole of the rotating clamping groove, the input part is rotated to drive the locking part to rotate in the special-shaped hole, so that the locking part is positioned on the hole shoulder of the special-shaped hole to limit the locking part from being separated from the special-shaped hole.

[0089] In one embodiment, the linkage component 9 comprises two groups of turn lock assemblies 91 arranged on the upper and lower sides of the window fan 7 respectively, and a synchronization assembly 92 for connecting the two groups of turn lock assemblies 91, the synchronization assembly 92 comprises an input unit 921 arranged on the window fan 7, and two connecting rod units 922 respectively connected with the two groups of turn lock assemblies 91, the connecting rod unit 922 comprises a driving end 901 connected with the input unit 921, and a swing end 902 connected with the shaft hub of the turn lock piece 911, and the locking part comprises a protruding end and a long arc plate arranged on the protruding end, and the special-shaped hole comprises a long through hole and a circular blind hole arranged in sequence. In this way, after the long arc plate is inserted into the long through hole, the input unit 921 synchronously drives the two connecting rod units 922, so that the long arc plates of the two groups of turn lock assemblies 91 are rotated in the circular blind hole, and the hole shoulder of the long through hole locks the long arc plates in the circular blind hole.

[0090] In one embodiment, the input unit 921 includes a rotational input member 923 rotatably connected to the window sash 7, the driving end 901 includes a driving swing plate 924 connected to the hub of the rotational input member 923, and the connecting rod unit 922 includes a linkage rod assembly 925 connecting the driving swing plate 924 and the swing end 902. In this way, the rotational input member 923 drives the driving swing plate 924 to swing, which drives the linkage rod assembly 925 to drive the rotational input member 923 to rotate.

[0091] In one embodiment, the linkage rod assembly 925 includes a first connecting rod 9251, a first sliding block 9252, a linkage rod 9253, a second sliding block 9254, and a second connecting rod 9255, which are sequentially connected. The first sliding block 9252 and the second sliding block 9254 are respectively slidably connected to the window sash 7, and the linkage rod 9253 links the first sliding block 9252 and the second sliding block 9254. The first connecting rod 9251 is connected to the driving swing plate 924, and the second connecting rod 9255 is connected to the swing end 902. In this way, when the swing plate 924 is driven to swing, it drives the first connecting rod 9251 and causes the first sliding block 9252 to slide on the window sash 7. The linkage rod 9253 causes the second sliding block 9254 and the first sliding block 9252 to slide synchronously, thereby driving the second connecting rod 9255 to swing.

When the second detection unit detects that the distance and angle between the screen fan 8 and the window sash 7 are not within the preset value, the electric push rod pushes the sliding end 31 to move along the length direction of the sliding long slot 22, and the locking part is inserted into the special-shaped hole of the rotating slot; when the second detection unit detects that the distance and angle between the screen fan 8 and the window sash 7 are the preset value, the driving motor drives the rotating input member 923 to rotate, so that the locking part and the hole shoulder of the special-shaped hole are placed against each other and the locking part is limited to not escaping from the special-shaped hole. After the first detection unit detects the rotation angle of the rotary lock member 911, it ensures that the screen fan 8 and the window sash 7 are arranged parallel to the same angle relative to the window frame 6; the electric push rod pushes the sliding end 31 to move along the length direction of the sliding long slot 22, thereby realizing the automatic opening and closing of the screen fan 8 and the window sash 7.
