Abstract
Description
Technical Field
[0001] This utility model relates to the field of door and window technology, and in particular to a flip handle and door and window system. Background Technology
[0002] In door and window systems, the locking of the window sash and the window frame is often achieved through the cooperation of the hook lock structure on the window sash and the lock seat structure on the window frame.
[0003] In related technologies, the handle is connected to the latch of the hook lock structure via a transmission mechanism. Rotating the handle causes the latch of the hook lock structure to extend or retract. Since rotating the handle requires the transmission mechanism and the latch of the hook lock structure to move, the user needs to apply a certain amount of force to rotate the handle.
[0004] In some applications, to prevent accidental injury to users when the latch of the hook lock extends, the hook lock is usually placed at a higher position, while the handle is usually placed at a lower position for easy operation. As a result, the span of the transmission mechanism between the hook lock and the handle is relatively large, and users need to exert more force to turn the handle. Utility Model Content

[0063] The technical solution of this utility model will be further described below with reference to the embodiments and accompanying drawings.
[0064] Example 1
[0065] See Figures 1 to 7 This application provides a flip handle, including: a mounting member 10; a first movable member 20, movably disposed between a first position and a second position of the mounting member 10; a second movable member 30, movably disposed between the first position and the second position of the first movable member 20; an operating member 40, rotatably connected to the first position of the mounting member 10 and the second position of the operating member 40; a first elastic member 50, used to provide positioning force for the starting and ending positions of the rotation of the operating member 40, and the first elastic member 50 is disposed between the first movable member 20 and the second movable member 30; rotating the operating member 40 drives the second movable member 30 to move, thereby driving the first movable member 20 to move.
[0066] In this utility model, the mounting part 10 in the flip handle is rotatably connected to the first position of the operating part 40, and the second moving part 30 is rotatably connected to the second position of the operating part 40. The mounting part 10, the operating part 40, the first moving part 20 and the second moving part 30 form a lever mechanism, which allows the user to rotate the operating part 40 by applying a relatively small force. Furthermore, a first elastic part 50 is provided to provide positioning force for the starting and ending positions of the rotation of the operating part 40, preventing the operating part 40 from becoming loose at its starting and ending positions.
[0067] It should be noted that, since the mounting component 10 and the second moving component 30 are rotatably connected to the operating component 40 at different positions, there is a gap between the rotation axis of the first rotating shaft 60 and the rotation axis of the second rotating shaft 70. During the rotation of the operating component 40, the second moving component 30 moves between the first position and the second position of the first moving component 20, and the second moving component 30 drives the first moving component 20 to move between the first position and the second position of the mounting component 10.
[0068] For example, the first movable component 20 is slidably connected to the mounting component 10, and the second movable component 30 is slidably connected to the first movable component 20.
[0069] In this embodiment, the mounting component 10 is rotatably connected to the operating component 40 at a first position via a first rotating shaft 60, and the second moving component 30 is rotatably connected to the operating component 40 at a second position via a second rotating shaft 70. The first rotating shaft 60 and the second rotating shaft 70 are arranged parallel to each other.
[0070] In this embodiment, the rotation angle range of the operating member 40 is 0°-180°. When the operating member 40 is at the starting position of rotation and when the operating member 40 is at the ending position of rotation, the operating member 40 is parallel to the mounting member 10. The rotation axis of the operating member 40 is perpendicular to the axial direction of the mounting member 10, and the rotation axis of the operating member 40 is perpendicular to the elastic force direction of the first elastic member 50.
[0071] See Figure 6When the operating member 40 is set to the 0° position, the operating member 40 is at the starting position of rotation. At this time, the operating member 40 and the first elastic member 50 are set perpendicular to each other, the second moving member 30 is set coaxially with the first elastic member 50, and there is a gap between the first rotating shaft 60 and the second rotating shaft 70. The first elastic member 50 pushes the operating member 40 through the second moving member 30, and the operating member 40 has a tendency to rotate in the -1° direction. Since the operating member 40 and the mounting member 10 are parallel to each other at this time, the mounting member 10 provides a limit for the operating member 40, and the operating member 40 is pressed against the mounting member 10. As a result, the operating member 40 cannot continue to rotate in the -1° direction. Thus, the first elastic member 50 provides a positioning force for the starting position of the rotation of the operating member 40, preventing the operating member 40 from loosening at its starting position of rotation.
[0072] See Figure 7 When the operating member 40 is set to the 180° position, the operating member 40 is at the rotation termination position. At this time, the operating member 40 and the first elastic member 50 are set perpendicular to each other, the second moving member 30 is set coaxially with the first elastic member 50, and there is a gap between the first rotating shaft 60 and the second rotating shaft 70. The first elastic member 50 pushes the operating member 40 through the second moving member 30, and the operating member 40 has a tendency to rotate in the 181° direction. Since the operating member 40 and the mounting member 10 are parallel to each other at this time, the mounting member 10 provides a limit for the operating member 40, and the operating member 40 is pressed against the mounting member 10. As a result, the operating member 40 cannot continue to rotate in the 181° direction. Thus, the first elastic member 50 provides a positioning force for the rotation termination position of the operating member 40, preventing the operating member 40 from loosening at its rotation termination position.
[0073] In this embodiment, the first moving member 20 moves along a first direction between a first position and a second position of the mounting member 10, and the second moving member 30 moves along a second direction between the first position and the second position of the first moving member 20, wherein the first direction and the second direction are perpendicular to each other.
[0074] For example, the first direction is the axial direction of the mounting part 10.
[0075] In this embodiment of the application, the first movable member 20 is provided with a mounting hole 201, which extends along the second direction. The first elastic member 50 and the second movable member 30 are both disposed in the mounting hole 201, and the second movable member 30 moves along the extending direction of the mounting hole 201.
[0076] For example, the second direction is the axial direction of the mounting hole 201.
[0077] For example, the first elastic element 50 is a spring, one end of the first elastic element 50 is connected and fixed to the first moving element 20, and the other end of the first elastic element 50 is connected and fixed to the second moving element 30.
[0078] See Figures 6 to 7 The first moving part 20 provides guidance for the movement of the second moving part 30 through the mounting hole 201. Rotating the operating part 40 can drive the second moving part 30 to slide up and down along the mounting hole 201, and the second moving part 30 can drive the first moving part 20 to move left and right.
[0079] In this embodiment, the operating component 40 includes an operating body 402 and a cam body 403. The operating body 402 is connected and fixed to the cam body 403. The mounting component 10 is rotatably connected to the operating body 402, and the second moving component 30 is rotatably connected to the cam body 403.
[0080] In this embodiment, the operating member 40 is provided with a first operating part 401; the mounting member 10 includes a base 102 and a cover 103, the base 102 and the cover 103 are connected to each other, and the base 102 and / or the cover 103 are provided with a second operating part 101; the base 102 is rotatably connected to the first position of the operating member 40, and the cover 103 is provided with a slot 104 for engaging the operating member 40.
[0081] To reduce production difficulty and facilitate assembly, the mounting component 10 is made in a split form, with the base 102 and the cover 103 connected as one unit by screws and other structures.
[0082] It should be noted that when the flip handle is installed on the door and window system, it can be connected to the hook lock structure 120 for transmission. When the flip handle is rotated, the latch 1202 of the hook lock structure 120 can be extended or retracted. When the flip handle is rotated to the starting position or the ending position, the operating part 40 can be inserted into the slot 104. Then, the user can push the second operating part 101 on the mounting part 10 to move the window sash 100. This avoids the operating part 40 from rotating when the second operating part 101 of the mounting part 10 is pushed. As a result, during the movement of the window sash 100, the latch 1202 of the hook lock structure 120 can be prevented from extending due to the rotation of the operating part 40.
[0083] In this embodiment of the application, the mounting member 10 is provided with a first guide portion 105 and a second guide portion 106, and the first moving member 20 is provided with a third guide portion 202 and a fourth guide portion 203; the first guide portion 105 and the third guide portion 202 cooperate with each other, and the second guide portion 106 and the fourth guide portion 203 cooperate with each other.
[0084] For example, the first guide portion 105 includes a strip-shaped hole extending along the axial direction of the mounting member 10, the second guide portion 106 includes a guide post, the third guide portion 202 includes a guide post, and the fourth guide portion 203 includes a strip-shaped hole extending along the axial direction of the mounting member 10; the length of the strip-shaped hole is greater than the outer diameter of the guide post, and the width of the strip-shaped hole is greater than or equal to the outer diameter of the guide post, so that the guide post slides relative to the axial direction of the strip-shaped hole; the mounting hole 201 is provided on the third guide portion 202.
[0085] See Figure 3 as well as Figure 4 When the first moving member 20 moves, the third guide portion 202 slides along the first guide portion 105, and the second guide portion 106 slides along the fourth guide portion 203.
[0086] Thus, by the cooperation of the first guide portion 105 and the third guide portion 202, and the cooperation of the second guide portion 106 and the fourth guide portion 203, the first moving member 20 can move between the first position and the second position of the mounting member 10.
[0087] In this embodiment, the flap handle further includes a second elastic member 80 and a third movable member 90, wherein the third movable member 90 is connected to the edge of the mounting member 10 via the second elastic member 80.
[0088] For example, the second elastic member 80 and the third movable member 90 are disposed at the end of the mounting member 10. When the mounting member 10 is installed on the window sash 100 of the door and window system, the mounting member 10 can be inserted into the corresponding connection hole on the window sash 100 by compressing the third movable member 90. After the installation is completed, the third movable member 90 extends under the action of the second elastic member 80, thereby improving the installation stability of the mounting member 10 and reducing the risk of falling off.
[0089] Furthermore, the second elastic member 80 can be a spring, the third moving member 90 can be a pin, one end of the second elastic member 80 is connected and fixed to the mounting member 10, and the other end of the second elastic member 80 is connected and fixed to the third moving member 90.
[0090] Example 2
[0091] See Figures 8 to 14 Unlike Embodiment 1, the operating component 40 in this embodiment is an integral structure.
[0092] Example 3
[0093] See Figures 1 to 7 as well as Figures 15 to 17This application provides a door and window system, including a window sash 100, a window frame 110, a hook lock structure 120, a lock seat structure 130, and the aforementioned flip handle; the flip handle and the hook lock structure 120 are disposed on the window sash 100, and the lock seat structure 130 is disposed on the window frame 110, with the hook lock structure 120 and the lock seat structure 130 cooperating with each other; the hook lock structure 120 includes a transmission component 1201 and a lock tongue 1202, and the first moving component 20, the transmission component 1201, and the lock tongue 1202 are connected by transmission, and the lock tongue 1202 is extended or retracted by rotating the flip handle.
[0094] It should be noted that the door and window system in this application embodiment adopts the flip-top handle in embodiment 1.
[0095] The door and window system in this invention uses the aforementioned flip handle, which is more labor-saving and easier to use.
[0096] The transmission component 1201 is movably disposed between the first position and the second position of the window sash 100. By rotating the operating component 40, the first moving component 20 is driven to move between the first position and the second position of the mounting component 10. In turn, the first moving component 20 drives the transmission component 1201 to move between the first position and the second position of the window sash 100, thereby the transmission component 1201 drives the extension or retraction of the locking tongue 1202.
[0097] When the window sash 100 moves to the closed position along the track of the window frame 110, the first moving part 20 is moved to the first position of the mounting part 10 by rotating the operating part 40. At this time, the locking tongue 1202 of the hook lock structure 120 extends and engages with the lock seat structure 130 to lock, thereby locking the window sash 100 to the window frame 110. When the first moving part 20 is moved to the second position of the mounting part 10 by rotating the operating part 40, the locking tongue 1202 of the hook lock structure 120 retracts, and the hook lock structure 120 and the lock seat structure 130 separate. The user can push the mounting part 10 of the flip handle to move the window sash 100 along the track of the window frame 110, thereby opening the window sash 100.
[0098] It should be noted that the transmission mechanism in the relevant technology can be directly used to realize the transmission connection between the transmission component 1201 and the locking tongue 1202, thereby converting the longitudinal linear motion of the transmission component 1201 into the swinging motion or the lateral motion of the locking tongue 1202. For example, a slant mechanism or a linkage mechanism can be used, which will not be elaborated here.
[0099] Example 4
[0100] See Figures 8 to 14 as well as Figures 18 to 20 Unlike Embodiment 3, the door and window system in this embodiment uses the flip-top handle from Embodiment 2.
[0101] The technical means disclosed in this utility model are not limited to those disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications are also considered within the scope of protection of this utility model.
