Description

Technical Field

[0001] The utility model relates to the technical field of hardware, in particular to a sequential closing mechanism for double-opening doors and windows. Background Art

[0002] Doors and windows are components of buildings and are classified as either enclosures or partitions depending on their location. They have different design requirements, requiring them to provide insulation, heat insulation, sound insulation, waterproofing, and fire protection. If a double-leaf sash is not closed in sequence, the sash that closes first will be blocked by the second sash and unable to close. This can result in inadequate protection from wind and rain, and in the case of fire and smoke-resistant doors and windows, it can cause loss of life and property. Publication No. CN1807823A discloses an electric casement door and window with an improved sliding support mechanism that avoids the presence of a dead zone during automatic opening and closing. The door and window comprise: a sash body; a frame; first and second slide rails mounted on the sash body and frame, respectively; first and second sliders embedded in the first and second slide rails, respectively; a first connecting rod in a bent or curved shape, one end of which is hinged to the first slider and the other end to the second slide rail; a second connecting rod, one end of which is hinged to the second slider and the other end to the first connecting rod; and an electric actuator, the drive mechanism of which is connected to the second slider. Although this door and window avoids the existence of dead zones, it is impossible to control the window sashes to close in sequence. Utility Model Content

[0024] See attached Figure 1 To the attached Figure 5As shown, a sequential closing mechanism for double-opening doors and windows includes a bracket 1, a first limit member 2, a connecting mechanism, and a sliding mechanism. The sliding mechanism is connected to the second leaf, one end of the first limit member 2 swings to press the sliding mechanism, and the other end of the first limit member 2 presses the connecting mechanism. The connecting mechanism is connected to the first leaf, wherein the bracket 1 is rotated to connect to the first limit member 2. When the first leaf is not closed, the first limit member 2 limits the movement of the sliding mechanism to restrict the closing of the second leaf.

[0025] In this embodiment, the sliding mechanism includes a slider 4 , on which a second limiting member 41 is provided. The end of the first limiting member 2 abuts against and presses the second limiting member 41 .

[0026] In this embodiment, a rotating shaft 11 is connected between the bracket 1 and the first limit member 2, and the connecting mechanism includes a pressure plate 3. A return spring 12 is mounted on the rotating shaft 11, and an extension portion 121 is extended from the end of the return spring 12. The extension portion 121 presses against the top pressure plate 3. The pressure plate 3 is connected to the first fan, and the return spring 12 is used to drive the first limit member 2 to swing and reset, so that the first limit member 2 continues to press against the second limit member 41.

[0027] In this embodiment, a mounting groove 112 is formed on the outer side wall of the middle portion of the rotating shaft 11 . The mounting groove 112 is annularly arranged and is used to mount the reset spring 12 .

[0028] In this embodiment, after the first position-limiting member 2 releases the slider limit 4 , the slider 4 has a stroke for continuing to slide, that is, the slider 4 can continue to slide closer to the first position-limiting member 2 .

[0029] In this embodiment, a gasket 21 is provided on the first position-limiting member 2 . The first position-limiting member 2 has a mounting hole. The rotating shaft 11 passes through the mounting hole and is connected to the gasket 21 .

[0030] In this embodiment, a clamp 111 is provided on the rotating shaft 11 , and the clamp 111 is located between the bracket 1 and the first limiting member 2 .

[0031] In this embodiment, a first limiting portion 23 is formed at the end of the first limiting member 2, and the first limiting portion 23 is bent to form a second limiting portion 24. The middle part of the extension portion 121 blocks the second limiting portion 24, and the limiting portion 24 resists the top pressure bracket 1 to limit the maximum rotation stroke of the first limiting member 2 when it rotates and resets; specifically, a third limiting portion 31 is bent to form at the end of the pressure plate 3, and the first limiting portion 23 blocks the third limiting portion 31.

[0032] In this embodiment, the slider 4 is connected to a support rod 5, and the support rod 5 is connected to the second leaf.

[0033] In this embodiment, the pressing plate 3 can be selected from a variety of specifications according to actual conditions, such as the attached Figure 4 The long specifications can also be selected with Figure 5The short specification in .

[0034] In this embodiment, after the first and second sashes are both opened, when they need to be closed, if the second sash is closed first, the support rod 5 will be pushed to move when the second sash is closed. However, since the support rod 5 is connected to the slider 4 and the first stopper 2 abuts against and presses the second stopper 41 to limit the movement of the slider 4, the second sash will be restricted from closing. In this way, the second sash cannot be closed without the first sash being closed, and a closing passage for the first sash is left.

[0035] When the first door is closed, the first door swings closed to drive the pressure plate 3 to swing. The pressure plate 3 contacts the first limit part 23 through the third limit part 31 to push the first limit member 2 to swing, so that the first limit member 2 is disengaged from the second limit member 41, and the slider 4 slides without restriction, so that the second door can be pushed to continue closing.

[0036] When the second sash is opened, the slider 4 moves away from the first limit member 2. At this time, under the action of the return spring 12, the first limit member 2 is pushed to swing and reset until the limiting portion 24 of the first limit member 2 contacts the top-pressing bracket 1, thereby limiting the first limit member 2 from continuing to rotate. In this way, after the slider 4 slides back, the first limit member 2 continues to contact the top-pressing second limit member 41 to limit the slider 4 from continuing to slide, thereby limiting the second sash from closing again after opening.

[0037] In this embodiment, a space is provided between the first limit member 2 and the bracket 1 to allow the slider 4 to continue sliding; the bracket 1 can be tilted on the groove to facilitate adjustment; the pressure plate 3 can be fixed to the first leaf by screws, or it can be installed by using the groove of the false middle bar on the first leaf.

[0038] The embodiments described above are merely preferred embodiments of the present invention and are not intended to limit the present invention in any way. Any person skilled in the art may, without departing from the scope of the present invention, utilize the technical content disclosed above to make further possible variations and modifications to the present invention, or to modify the present invention into equivalent embodiments with equivalent variations. Therefore, any equivalent variations made in accordance with the principles of the present invention without departing from the scope of the present invention shall be included within the scope of protection of the present invention.
