Description

Technical Field

[0001] The invention relates to the technical field of doors and windows, and in particular to a rotary opening and closing type sliding door and window. Background Art

[0002] At present, sliding doors and windows have the advantages of small space occupation, convenient sliding and pulling, and beautiful appearance, so they are widely welcomed.

[0003] The existing utility model patent with authorization announcement number CN106874162U discloses a translation sliding window. The translation sliding window forms a good sealing effect through a three-seal strip structure.

[0004] The above-mentioned prior art solution has the following problems: the window sash can only be pushed open horizontally and cannot be rotated open, which cannot be achieved when one wants to let in air only from the upper side of the window sash to avoid the wind blowing directly on the face. Summary of the invention

[0005] In view of the shortcomings of the prior art, the purpose of the present invention is to provide a rotary opening and closing type sliding door and window, which has the advantage that the door and window can be opened by both sliding and rotating.

[0006] The above-mentioned inventive object of the present invention is achieved through the following technical scheme: a rotary opening and closing type flat-sliding door and window, comprising a door and window frame, a fixed door and window leaf and a movable door and window leaf located in the door and window frame, wherein the upper and lower bottom surfaces in the frame of the door and window frame are respectively formed with an upper track groove and a lower track groove, and the movable door and window leaf comprises a door and window leaf body, a lower sliding assembly connected to the door and window leaf body, an upper sliding assembly connected to the door and window leaf body, and a switching assembly for operating the state switching of the movable door and window leaf, the lower sliding assembly comprises a first lower slider and a second lower slider that slide along the lower track groove; the upper sliding assembly comprises a first upper slider that is embedded in the upper track groove and moves along the upper track groove, a second upper slider and an upper locking seat fixed to the upper bottom surface of the inner side of the door and window frame, the lower side of the first upper slider is rotatably connected to a first upper hinge plate whose axis is along the vertical direction, the lower side of the second upper slider is rotatably connected to a second upper hinge plate whose axis is along the vertical direction, and the ends of the first upper hinge plate and the second upper hinge plate away from the door and window frame are both rotatably connected to the door and window leaf body.

[0007] By adopting the above technical solution, in the horizontal push state, the switching component switches to the state where the upper locking seat positions the second upper slider. The first upper slider, the second upper slider, the first lower slider and the second lower slider slide along the upper track groove and the lower track groove to realize the horizontal push opening of the movable door and window sash. When it is necessary to rotate and open the door and window, the upper locking seat is unlocked, and the upper end of the movable door and window sash is rotated inward, and the first upper hinge plate and the second upper hinge plate are relatively rotated to unfold, so that the distance between the upper end of the movable door and window sash and the door and window frame is opened by the length of the first upper hinge plate and the second upper hinge plate, while the first lower slider and the second lower slider are still located in the lower track groove, so that the door and window are rotated to open, and the air only enters from the upper side of the door and window sash.

[0008] In a preferred example, the present invention can be further configured as follows: a guide ridge extending along the length direction of the lower track groove is formed on the inner bottom surface of the lower track groove, and the lower sides of the first lower sliding block and the second lower sliding block are rotatably connected to two rollers, and an annular groove is formed on the outer ring surface of each roller, the roller is located in the lower track groove, and the guide ridge is inserted into the annular groove.

[0009] By adopting the above technical solution, the rollers of the first lower slider and the second lower slider cooperate with the lower track groove so that the first lower slider and the second lower slider move along the lower track groove. The guide convex strip is inserted into the annular groove, so that the movement along the lower track groove is more stable.

[0010] In a preferred example, the present invention can be further configured as follows: the side of the fixed door and window sash facing outside the door and window is fixedly connected to the door and window frame, a gap is left between the upper and lower sides of the fixed door and window sash facing the indoor side and the door and window frame, and the upper track groove and the lower track groove pass through the upper and lower sides of the fixed door and window sash; the first lower sliding block and the second lower sliding block are both formed with grooves on the sides facing the indoor side, and the two grooves are rotatably connected with lower hinged plates with axes along the vertical direction, and the ends of the two lower hinged plates away from the grooves are rotatably connected to the door and window sash body.

[0011] By adopting the above technical solution, gaps are left on the upper and lower sides of the fixed door and window sashes to allow the lower hinge plate and the first upper hinge plate and the second upper hinge plate to pass through. When the movable door and window sash is pushed open, the lower hinge plate and the first upper hinge plate and the second upper hinge plate are extended, so that the movable door and window sash moves to the position of the fixed door and window sash facing the indoor side, and is smoothly pushed open. When the movable door and window sash is closed, it can be closed in a state flush with the fixed door and window sash.

[0012] In a preferred example of the present invention, it can be further configured as follows: a cam is provided in the groove of the second lower sliding block and is integrally formed with the lower hinge plate, and a guide groove extending to the right is formed on the upper surface of the second lower sliding block at a position on the right side of the cam, and a push plate is provided on the upper side of the second lower sliding block, and the right side of the push plate is bent downward to form an abutment plate, and the lower side surface of the push plate is integrally formed with a square block passing through the guide groove, and one end of the square block that penetrates downward into the groove is fixedly connected with a push block with a diameter greater than the width of the guide groove, a compression spring is connected between the right side surface of the guide groove and the square block, and the right end of the second lower sliding block is rotatably connected to the outward side of the right end of the second lower sliding block with an axis pointing horizontally in the inward and outward directions, the lower locking block extends to the right to be formed with a lower locking plate, and the right end of the lower locking plate extends toward the direction of the room to be formed with a lock hook, and an abutment groove is formed on the lower locking block at a position above the right side of the rotation connection, and the abutment plate is located in the abutment groove.

[0013] By adopting the above technical solution, when the movable door and window sash is closed and the angle between the lower hinge plate and the second lower slider decreases, the cam pushes the push block and the push plate to move rightward, the abutment plate pushes the lower lock plate to rotate to a horizontal position, the lock hook is hooked on the protrusion, and the position of the movable door and window sash is fixed. When the movable door and window sash is opened, when the angle between the lower hinge plate and the second lower slider increases, the compression spring pushes the push block and the push plate to move leftward until the push block is inserted into the slot, and at the same time, the abutment plate abuts against the left end surface of the abutment slot to drive the lower lock block to rotate, so that the lock hook is upwardly disengaged from the protrusion.

[0014] In a preferred example, the present invention can be further configured as follows: a slot is formed on the right side of the cam; when the movable door or window is opened, when the angle between the lower hinge plate and the second lower sliding block becomes larger, the compression spring pushes the push block and the push plate to move to the left until the push block is stuck in the slot.

[0015] By adopting the above technical solution, a slot is formed on the right side of the cam so that the push block can be inserted into the slot. When the hand does not apply a large force, the push block will not fall out of the slot, which means that when the movable door and window sash is in the platform open state, the lower hinge plate will not rotate arbitrarily.

[0016] In a preferred example, the present invention can be further configured as follows: the lower side surface of the second upper hinged plate connected to one end of the second upper slider is fixedly connected with an upper locking block, the upper locking block is waist-shaped, the upper locking seat includes a vertical plate fixedly connected to the door and window frame, a horizontal plate extending horizontally from the lower end of the vertical plate, and the upper side surface of the horizontal plate is integrally formed with a first limiting plate and a second limiting plate arranged at intervals, and the second limiting plate is located on the side of the first limiting plate facing the room. The left end of the second limiting plate is arc-shaped and extends in a direction close to the first limiting plate, and the minimum spacing between the first limiting plate and the second limiting plate is greater than the width of the upper locking block and less than the length of the upper locking block.

[0017] By adopting the above technical solution, when the movable door and window sash is closed, the locking block slides to the position between the first limit plate and the second limit plate, and during the process of the angle between the second upper hinge plate and the second upper slider decreasing, the locking block rotates to a state where the length direction points to the indoor direction. At this time, the left side of the locking block abuts against the second limit plate, and the right side abuts against the limit block, and the position of the second upper slider is fixed. When opening the door and window sash, only the door and window sash body rotates first, and when the length direction of the locking block points to the left and right direction, the door and window sash can be pushed open horizontally.

[0018] In a preferred example, the present invention can be further configured as follows: the horizontal lower side surface is rotatably connected to an upper locking plate whose axis is along the vertical direction, and an arc-shaped hole with the rotational connection point between the upper locking plate and the horizontal plate as the center is formed on the horizontal plate at the right side of the first limiting plate, and the end of the upper locking plate away from the rotational connection extends upward to form a limiting block passing through the arc-shaped hole.

[0019] By adopting the above technical solution, when the limit block abuts against the right side of the upper locking block, the second upper sliding block cannot continue to slide to the right. When the limit block moves to the end of the arc hole close to the outside, the limit block no longer restricts the upper locking block from moving to the right, and the second upper sliding block can slide to the right to adapt to the rotation of the movable door and window sash.

[0020] In a preferred example, the present invention can be further configured as follows: the switching assembly includes an operating handle located on the left side of the movable door and window sash facing the indoor direction, a gear located inside the movable door and window sash and rotating together with the operating handle, a rack located inside the movable door and window sash and meshing with the gear, a sliding member fixedly connected to the rack, and a lock member moved by the sliding member, wherein the lock member includes a top lock column located on the upper end surface of the movable door and window sash; a force groove is formed on the side of the upper locking plate facing the indoor room at a position to the left of the rotation connection point between the upper locking plate and the horizontal plate, and the top lock column is inserted into the force groove.

[0021] By adopting the above technical solution, when the operating handle is facing upward, the movable door and window sash is in a rotating state, and the sliding member is driven to move by the cooperation of the gear rack during the rotation of the operating handle. The top lock column pushes the limit block to rotate to the end of the arc hole close to the outside, and the second upper slider can continue to slide to the right.

[0022] In a preferred example, the present invention can be further configured as follows: the lock includes a lower left small lock column located on the left side of the movable door and window sash near the lower end, and a lower right small lock column located on the side of the movable door and window sash near the lower end; a first lower left lock plate is fixed to the right side of the fixed door and window sash near the lower end, and a lower right lock plate is fixed to the right side of the door and window frame near the lower end; when the operating handle is facing upwards, the movable door and window sash is in a rotating state, and the lower left small lock column abuts against the first lower left lock plate, and the lower right small lock column abuts against the lower right lock plate.

[0023] By adopting the above technical solution, when the sliding member moves, the positions of the first lower left small lock column and the lower right small lock column are also changed and adjusted accordingly. When the movable door and window sash rotates, the lower left small lock column abuts against the first lower left lock plate, and the lower right small lock column abuts against the lower right lock plate, so that the lower end of the movable door and window sash cannot continue to rotate toward the indoor direction.

[0024] In a preferred example, the present invention can be further configured as: a lower left large lock column above the lower left small lock column, an upper left large lock column located on the left side of the movable door and window sash near the upper end, a lower right large lock column above the lower right small lock column, and an upper right large lock column located on the right side of the movable door and window sash near the upper end; a second lower left lock plate is provided above the first lower left lock plate, an upper left lock plate is fixed on the right side of the fixed door and window sash near the upper end, and an upper right lock plate is fixed on the right side of the door and window frame near the upper end; when the operating handle is facing downward, the movable door and window sash is in a closed state, the lower left large lock column abuts against the second lower left lock plate, the upper left large lock column abuts against the upper left lock plate, the lower right large lock column abuts against the lower right lock plate, and the upper right large lock column abuts against the upper right lock plate.

[0025] By adopting the above technical solution, when the sliding part moves, the lower left large lock column, the upper left large lock column, the lower right large lock column, and the upper right large lock column move together, and when the lower left large lock column abuts against the second lower left lock plate, the upper left large lock column abuts against the upper left lock plate, the lower right large lock column abuts against the lower right lock plate, and the upper right large lock column abuts against the upper right lock plate, the position of the movable door and window sash is completely fixed.

[0026] In summary, the present invention includes at least one of the following beneficial technical effects:

[0027] 1. In the horizontal push state, the switching assembly switches to the state where the upper lock seat positions the second upper slider, and the first upper slider, the second upper slider, the first lower slider and the second lower slider slide along the upper track groove and the lower track groove to realize the horizontal push opening of the movable door and window sashes. When the door and window need to be rotated to open, the upper lock seat is unlocked, and the upper end of the movable door and window sash is rotated inward, and the first upper hinge plate and the second upper hinge plate are relatively rotated to unfold, so that the distance between the upper end of the movable door and window sash and the door and window frame is opened by the length of the first upper hinge plate and the second upper hinge plate, and the first lower slider and the second lower slider are still located in the lower track groove, so that the door and window are rotated to open, and air only enters from the upper side of the door and window sash;

[0028] 2. When the movable door and window sash is closed and the angle between the lower hinge plate and the second lower sliding block decreases, the cam pushes the push block and the push plate to move to the right, and the abutment plate pushes the lower lock plate to rotate to a horizontal position. The lock hook is hooked on the protrusion, and the position of the movable door and window sash is fixed; when the movable door and window sash is opened, the angle between the lower hinge plate and the second lower sliding block increases, and the compression spring pushes the push block and the push plate to move to the left until the push block is inserted into the slot. At the same time, the abutment plate abuts against the left end surface of the abutment slot to drive the lower lock block to rotate, so that the lock hook disengages from the protrusion upward.

[0042] like Figure 3 and Figure 4 As shown, the upper and lower bottom surfaces of the inner side of the door and window frame 1 are respectively formed with an upper track groove 4 and a lower track groove 5, and the inner bottom surface of the lower track groove 5 is formed with a guide convex strip 6 extending along the length direction of the lower track groove 5. Figure 5 and Figure 6 As shown, abutment platform 7 is formed near the right end of the lower bottom surface of the door and window frame 1, and a protrusion 8 is formed on the abutment platform 7. The side of the fixed door and window sash 2 facing the outside of the door and window is fixedly connected to the door and window frame 1, and gaps are left between the upper and lower sides of the side of the fixed door and window sash 2 facing the room and the door and window frame 1. The upper track groove 4 and the lower track groove 5 pass through the upper and lower sides of the fixed door and window sash 2.

[0043] like Figure 3 and Figure 4As shown, the movable door and window sash 3 includes a door and window sash body 9, a lower sliding assembly 10 connected to the door and window sash body 9, an upper sliding assembly 11 connected to the door and window sash body 9, and a switching assembly 12 ( Figure 2 The lower sliding assembly 10 includes a first lower sliding block 13, a second lower sliding block 14, and a lower connecting rod 15 connecting the first lower sliding block 13 and the second lower sliding block 14. The lower sides of the first lower sliding block 13 and the second lower sliding block 14 are rotatably connected to two rollers 16, and the outer ring surface of each roller 16 is formed with an annular groove 17. The roller 16 is located in the lower track groove 5, and the guide ridge 6 is inserted into the annular groove 17. Figure 5 and Figure 6 As shown, the first lower slider 13 and the second lower slider 14 are formed with grooves 18 on the sides facing the room, and the two grooves 18 are rotatably connected with lower hinge plates 19 with axes along the vertical direction. The ends of the two lower hinge plates 19 away from the grooves 18 are rotatably connected to the door and window sash body 9. Figure 7 As shown, a cam 20 integrally formed with the lower hinge plate 19 is provided in the groove 18 of the second lower slider 14, a slot 21 is formed on the right side of the cam 20, and a guide groove 22 extending to the right is formed on the upper surface of the second lower slider 14 at the right side of the cam 20. A push plate 23 is provided on the upper side of the second lower slider 14, the right side of the push plate 23 is bent downward to form an abutment plate 24, a square block 25 passing through the guide groove 22 is integrally formed on the lower side of the push plate 23, a push block 26 having a diameter greater than the width of the guide groove 22 is fixedly connected to one end of the square block 25 that penetrates downward into the groove 18, and a compression spring 27 is connected between the right side of the guide groove 22 and the square block 25. The right end of the second lower sliding block 14 is rotatably connected to the outward side with a lower locking block 28 whose axis is horizontally pointed in the inward and outward directions. The lower locking block 28 extends to the right to form a lower locking plate 29. The right end of the lower locking plate 29 extends toward the indoor direction to form a locking hook 30. The lower locking block 28 is formed with an abutment groove 31 at the upper right position of the rotation connection, and the abutment plate 24 is located in the abutment groove 31.

[0044] When the movable door and window 3 is closed, the angle between the lower hinge plate 19 and the second lower slider 14 decreases, the cam 20 pushes the push block 26 and the push plate 23 to move rightward, the abutment plate 24 pushes the lower lock plate 29 to rotate to a horizontal position, and the lock hook 30 is hooked on the protrusion 8. When the movable door and window 3 is opened, the angle between the lower hinge plate 19 and the second lower slider 14 increases, the compression spring 27 pushes the push block 26 and the push plate 23 to move leftward until the push block 26 is inserted into the slot 21, and at the same time, the abutment plate 24 abuts against the left end surface of the abutment slot 31 to drive the lower lock block 28 to rotate, so that the lock hook 30 is disengaged from the protrusion 8 upward.

[0045] like Figure 8 and Fig. 9As shown, the upper sliding assembly 11 includes a first upper slider 32 and a second upper slider 33 which are embedded in the upper track groove 4 and move left and right along the upper track groove 4, and an upper locking seat 34 which is fixed on the upper bottom surface of the inner side of the door and window frame 1. The lower side of the first upper slider 32 is rotatably connected with a first upper hinge plate 35 whose axis is along the vertical direction, and the lower side of the second upper slider 33 is rotatably connected with a second upper hinge plate 36 whose axis is along the vertical direction. The first upper hinge plate 35 and the second upper hinge plate 36 are both rotatably connected to the door and window sash body 9 at one end away from the door and window frame 1. The lower side surface of the second upper hinge plate 36 connected to one end of the second upper slider 33 is fixedly connected with an upper locking block 37, and the upper locking block 37 is waist-shaped. The right side of the first upper hinge plate 35 and the second upper hinge plate 36 close to one end of the window frame are both rotatably connected with a pull block 62, and a waist-shaped hole 63 is formed on the upper surface of the pull block 62, and a through column 64 passing through the waist-shaped hole 63 is formed on the upper end surface of the movable window sash. The waist-shaped hole 63 on the pull block 62 cooperates with the through column 64 to limit the maximum rotation angle of the first upper hinge plate 35 and the second upper hinge plate 36, so that the first upper hinge plate 35 and the second upper hinge plate 36 can no longer rotate when they rotate to the point where the through column 64 abuts against the right end of the waist-shaped hole 63, and at this time, the rotation angle of the first upper hinge plate 35 and the second upper hinge plate 36 is less than 90 degrees.

[0046] like Figure 8 and Fig. 9 As shown, the locking seat 34 includes a vertical plate 38 fixedly connected to the door and window frame 1, a horizontal plate 39 extending horizontally from the lower end of the vertical plate 38, and a locking plate 40 rotatably connected to the horizontal lower side along the vertical axis. The upper side of the horizontal plate 39 is integrally formed with a first limiting plate 41 and a second limiting plate 42 arranged at intervals, and the second limiting plate 42 is located on the side of the first limiting plate 41 facing the indoor room. The left end of the second limiting plate 42 is arc-shaped and extends in a direction close to the first limiting plate 41. The minimum spacing between the first limiting plate 41 and the second limiting plate 42 is slightly larger than the width of the locking block 37 and smaller than the length of the locking block 37. An arc-shaped hole 43 with the rotation connection point of the locking plate 40 and the horizontal plate 39 as the center is formed on the horizontal plate 39 at the right side of the first limiting plate 41. One end of the locking plate 40 away from the rotation connection extends upward to form a limiting block 44 passing through the arc-shaped hole 43. A stress-bearing groove 45 is formed on one side of the upper locking plate 40 facing the interior of the room and located on the left side of the rotation connection point between the upper locking plate 40 and the horizontal plate 39 .

[0047] When the movable door and window sash 3 is closed, the locking block 37 slides to the position between the first limit plate 41 and the second limit plate 42. During the process of reducing the angle between the second upper hinge plate 36 and the second upper slider 33, the locking block 37 rotates to a state where the length direction points to the indoor direction. At this time, the left side of the locking block 37 abuts against the second limit plate 42 and the right side abuts against the limit block 44, and the position of the second upper slider 33 is fixed. When opening the door and window sash, only the door and window sash body 9 rotates first, and when the length direction of the locking block 37 points to the left and right direction, the door and window sash can be pushed open horizontally.

[0048] like Fig.10 As shown, the switching assembly 12 includes an operating handle 46 located on the left side of the movable door and window 3 and facing the indoor direction, a gear 47 located in the movable door and window 3 and rotating with the operating handle 46, a rack 48 located in the movable door and window 3 and meshing with the gear 47, a sliding member 49 fixedly connected to the rack 48, and a lock member driven to move by the sliding member 49. The rack 48 is arranged in the vertical direction and located on the left side of the gear 47. When the handle is rotated in the clockwise direction, the rack 48 is driven to move upward, and when the handle is rotated in the counterclockwise direction, the rack 48 is driven to move downward.

[0049] like Fig.10 As shown, the sliding member 49 extends downward from the rack 48 to the left lower edge of the movable door and window sash 3, and the sliding member 49 extends upward from the rack 48, passes through the upper end of the movable door and window sash 3 and extends to the right lower edge of the movable door and window sash 3. When the sliding member 49 passes through the corners of the upper left corner and the upper right corner of the movable door and window sash 3, the corners are transitionally connected through the flexible shaft. The lock member includes a lower left small lock column 50 located on the left side of the movable door and window sash 3 near the lower end position, a lower left large lock column 51 above the lower left small lock column 50, an upper left large lock column 52 located on the left side of the movable door and window sash 3 near the upper end position, a lower right small lock column 53 located on the side of the movable door and window sash 3 near the lower end position, a lower right large lock column 54 above the lower right small lock column 53, an upper right large lock column 55 located on the right side of the movable door and window sash 3 near the upper end position, and a top lock column 56 located on the upper end surface of the movable door and window sash 3 near the right side.
