Description

Technical Field

[0001] This application relates to the technical field of window hinges, and more specifically, to an outward-opening and downward-swinging hinge. Background Art

[0002] The outward-opening and downward-swinging casement window realizes three states: window sash closed, window sash outward-opening to the outside of the room, and window sash downward-swinging to the outside of the room, saving indoor space. Among them, the upper hinge ensures that the upper part of the window sash can be opened outward to the outside of the room, the lower hinge ensures that the lower part of the window sash can be opened outward to the outside of the room, and the lower hinge also ensures that the lower part of the window sash can be suspended at a certain angle to the outside of the room. Therefore, when the window sash is suspended, a hinge is required for self-locking to be positioned at a certain angle.

When the stopping member abuts against the first acting member, it can drive the rotating member to rotate, so as to drive the mating member to move to hover at the stopping member; when the stopping member abuts against the second acting member, it can drive the stopping member and the mating member to be staggered.

[0008] In some of these embodiments, the first acting member is a boss provided on the rotating member, and the second acting member is an inclined wall provided on the sliding member; a pointed tip is provided on one side of the stopping member, and when the sliding member moves relative to the lower cantilever, it can drive the boss to abut against the pointed tip of the stopping member or drive the inclined wall to abut against the pointed tip of the stopping member.

[0009] In some of these embodiments, the mating member is a clamping body provided on the rotating member; a groove adapted to the clamping body is provided on the other side of the stopping member opposite to the pointed tip.

[0031] The terms "first", "second", etc. in the specification and claims of this application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0032] The present application embodiment provides an outward opening underhang hinge 100, such as Figures 1 to 4 As shown, the outward opening lower hanging hinge 100 includes a bottom plate 1, a load-bearing member 2, a connecting arm 3, a short arm 4, a lower cantilever 5 and a locking assembly 6. The bottom plate 1 is hinged to the connecting arm 3 through the load-bearing member 2, one end of the short arm 4 is hinged to the connecting arm 3, and the other end of the short arm 4 is hinged to the lower cantilever 5; wherein, the bottom plate 1 is used to fix the window frame, and the lower cantilever 5 is used to fix the window sash. When the lower cantilever 5 is in an open state relative to the bottom plate 1, the lower part of the window sash can be driven to open horizontally to the outside and hang at a certain angle relative to the window frame. When the lower cantilever 5 is in a closed state relative to the bottom plate 1, the window sash can be driven to close relative to the window frame to form a closed window state. Specifically, when the lower cantilever 5 is in an open state relative to the bottom plate 1, and the lower part of the window sash is opened horizontally to the outside and hangs at a certain angle relative to the window frame, the locking assembly 6 needs to be used to lock the window sash so that it is positioned at the window frame.

[0033] Specifically, the locking assembly 6 includes a sliding member 61, a stopper 62 and a rotating member 63; the sliding member 61 is slidably arranged on the lower cantilever 5, the connecting arm 3 is hinged to the sliding member 61, and the rotating member 63 is rotatably arranged on the sliding member 61; the rotating member 63 is provided with a matching member 631 and a first action member 632, the stopper 62 is movably arranged on the lower cantilever 5, and the sliding member 61 is provided with a second action member 611; the lower cantilever 5 is opened or released relative to the bottom plate 1 When closed, it can drive the sliding member 61 to reciprocate relative to the lower cantilever 5, so that the stop member 62 can switch to abut against the first acting member 632 or the second acting member 611; when the stop member 62 abuts against the first acting member 632, it can drive the rotating member 63 to rotate, so as to drive the matching member 631 to move to hover on the stop member 62; when the stop member 62 abuts against the second acting member 611, it can drive the stop member 62 and the matching member 631 to be staggered.

[0034] Specifically, when the window sash is opened, it drives the short arm 4 to rotate and open, so that the sliding member 61 slides forward until the stopper 62 abuts against the first acting member 632. When the stopper 62 abuts against the first acting member 632, it can drive the rotating member 63 to rotate to the limit position and stop, so as to drive the fitting member 631 to rotate from the initial state where it is staggered with the stopper 62 to the front of the stopper 62. At this time, the sliding member 61 retreats a certain distance to drive the fitting member 631 to move backward and hover over the stopper 62. At this time, the stopper 62 prevents the fitting member 631 from continuing to move backward. By preventing the fitting member 631 from moving backward, the stopper 62 achieves the purpose of preventing the sliding member 61 from moving backward, so that the window sash completes the fixed and suspended opening action.

[0035] When it is necessary to close the window sash: an external force acts on the window sash, driving the sliding member 61 to slide forward, so that the fitting member 631 disengages from the stopper 62. At this time, the stopper 62 abuts against the second acting member 611 and rubs against it, so that the position of the stopper 62 is staggered with that of the fitting member 631. The stopper 62 no longer prevents the fitting member 631 from moving backward. At this time, the sliding member 61 can move backward to achieve reset, and the suspended opening is closed. Specifically, when the stopper 62 abuts against the second acting member 611 and rubs against it, it can directly drive the stopper 62 to move relative to the lower cantilever 5 to stagger its position with that of the fitting member 631, or when the stopper 62 abuts against the second acting member 611 and rubs against it, the stopper 62 simultaneously abuts against the first acting member 632. At this time, the stopper 62 moves relative to the lower cantilever 5 away from the fitting member 631, and at the same time, the fitting member 631 can also move away from the stopper 62 under the rotation drive of the rotating member 63, so that the stopper 62 and the fitting member 631 move away from each other to form a staggered position state.

[0036] In summary, the outward-opening bottom-hinged hinge 100 can well bear the window sash through the cooperation of the bottom plate 1, the load-bearing member 2, the connecting arm 3, the short arm 4, and the lower cantilever 5, enabling the lower part of the window sash to open outwards and hang on the window frame. By providing the locking assembly 6 including the sliding member 61, the stop member 62, and the rotating member 63, when the window sash is opened, the short arm 4 is driven to rotate and open, so that the sliding member 61 of the locking assembly 6 slides forward until the stop member 62 abuts against the first acting member 632 of the rotating member 63. When the stop member 62 abuts against the first acting member 632, it can drive the rotating member 63 to rotate to the limit position and stop, so as to drive the cooperating member 631 to rotate from the initial state where it is staggered with the stop member 62 to the front of the stop member 62, making the stop member 62 prevent the cooperating member 631 from continuing to move backward to complete the fixed hanging-open action. When the window sash needs to be closed, the stop member 62 switches to abut against and friction with the second acting member 611, so that the stop member 62 is staggered with the cooperating member 631, and the stop member 62 no longer prevents the backward movement of the cooperating member 631. At this time, the sliding member 61 can move backward to achieve reset, and the hanging-open closing is completed. It can well switch to a stable locking state and an unlocking state according to the state of the window sash relative to the window frame, with good stability, and can effectively avoid loosening and unlocking in the hanging state, resulting in the self-closing of the window sash.

[0037] In some embodiments, as Figure 3 and Figure 4 shown, the first acting member 632 is a boss provided on the rotating member 63, and the second acting member 611 is an inclined wall provided on the sliding member 61; a pointed head 621 is provided on one side of the stop member 62. When the sliding member 61 moves relative to the lower cantilever 5, it can drive the boss to abut against the pointed head 621 of the stop member 62, or drive the inclined wall to abut against the pointed head 621 of the stop member 62. Among them, when the boss abuts against the pointed head 621 of the stop member 62, it can drive the rotating member 63 to rotate to the limit position and stop, so as to drive the cooperating member 631 to rotate from the initial state where it is staggered with the stop member 62 to the front of the stop member 62, making the stop member 62 prevent the cooperating member 631 from continuing to move backward to complete the fixed hanging-open action. When the inclined wall abuts against the pointed head 621 of the stop member 62, the stop member 62 abuts against and frictions with the inclined wall, so that the stop member 62 is staggered with the cooperating member 631, and the stop member 62 no longer prevents the backward movement of the cooperating member 631. At this time, the sliding member 61 can move backward to achieve reset, and the hanging-open closing is completed. Specifically, the pointed head 621 forms an inclined surface structure with two inclined sides, so that when the stop member 62 abuts against and frictions with the inclined wall, it can be guided by the inclined surface to make the stop member 62 move relative to the lower cantilever 5 to be staggered with the position of the cooperating member 631 in the sliding extension direction of the sliding member 61, facilitating the backward movement of the cooperating member 631 to achieve the hanging-open closed state.

[0038] In some embodiments, as Figure 4 shown, the fitting member 631 is a clamping body provided on the rotating member 63; on the other side of the stopper 62 opposite to the pointed head 621, there is a groove 622 adapted to the clamping body. Specifically, the clamping body is a cylindrical clamping body, and the groove 622 is an arc-shaped groove. Under the action of the sliding member 61 and the rotating member 63, the clamping body is driven to be clamped into the groove 622 to form an open state, or the clamping body is disengaged from the groove 622 to form a closed and open state, which can well form a guiding clamping or disengaging operation and improve smoothness.

[0039] In some embodiments, as Figure 2 and Figure 3 shown, a first guiding groove 51 perpendicular to the sliding direction of the sliding member 61 is provided on the lower cantilever 5, and a guiding convex body 623 is provided on the stopper 62. The guiding convex body 623 is movably arranged in the first guiding groove 51. Among them, by providing the first guiding groove 51 on the lower cantilever 5, the stopper 62 can reciprocate along the first guiding groove 51. When rubbing against the inclined wall, under the guiding action of the inclined surface, the stopper 62 can move along the first guiding groove 51 to be displaced from the position of the fitting member 631, facilitating the retreat of the fitting member 631 to achieve the closed and open state. In addition, it should be noted that the rotating member 63 is rotationally connected to the rotating hole on the sliding member 61 through a rotating shaft, and the rotating member 63 has the performance of restoring the original state under the condition of the external force being withdrawn, such as being provided with a conventional torsion spring structure, etc., so that when the stopper 62 is disengaged from the fitting member 631, the rotating member 63 can rotate to restore the original state under its own inertia condition.

[0040] In some embodiments, as Figure 4 shown, along the sliding direction of the sliding member 61, a second guiding groove 612 is provided on the sliding member 61. When the lower cantilever 5 opens or closes relative to the bottom plate 1, the stopper 62 can slide out of the second guiding groove 612 or slide into the second guiding groove 612. Among them, by providing the second guiding groove 612, when the sliding member 61 slides relative to the lower cantilever 5, the stopper 62 forms a relative sliding state relative to the sliding member 61. At this time, the stopper 62 can slide out along the second guiding groove 612 to abut against the first acting member 632 of the rotating member 63 to achieve the window sash open operation, or slide into the initial position under the guiding action of the second guiding groove 612 in the closed and open state, so that the stopper 62 can be in an accurate initial position when the closed and open state is completed, facilitating cyclic open operations or closed and open operations.

[0041] In some embodiments, as Figure 4As shown, on one side of the second guiding groove 612 close to the rotating member 63, an inclined guiding wall 613 is formed. When an external force acts on the window sash in the closed and suspended state, the sliding member 61 slides forward, causing the engaging member 631 to disengage from the stopping member 62. At this time, the stopping member 62 abuts against and rubs against the second acting member 611, causing the positions of the stopping member 62 and the engaging member 631 to be staggered. When the stopping member 62 moves forward relative to the sliding member 61, it can move from the staggered position to the initial position under the guiding action of the guiding wall 613 of the second guiding groove 612.

[0042] In some embodiments, as Figure 2 shown, the lower cantilever 5 is provided with a sliding groove 52, and the sliding member 61 is slidably arranged in the sliding groove 52. Through the arrangement of the sliding groove 52, the sliding member 61 can reciprocate in a straight line, so that the stopping member 62 can accurately abut against the first acting member 611 or the second acting member 632, so as to smoothly perform the locking or unlocking operation.

[0043] In some embodiments, as Figure 1 and Figure 2 shown, the load-bearing member 2 includes a first load-bearing plate 21, a second load-bearing plate 22 and a connecting rod 23; the opposite ends of the first load-bearing plate 21 are respectively hinged to the bottom plate 1 and the first end of the connecting arm 3, and the two ends of the second load-bearing plate 22 are respectively hinged to the bottom plate 1 and the first end of the connecting rod 23. The second end of the connecting rod 23 is hinged to the connecting arm 3, and the middle parts of the first load-bearing plate 21 and the second load-bearing plate 22 are arranged in a crossed manner and are hinged. Among them, through the crossed and rotatable arrangement of the first load-bearing plate 21 and the second load-bearing plate 22, the window sash can be smoothly opened or closed relative to the window frame, and the strength of the structure can be greatly enhanced, forming a super strong load-bearing capacity, enhancing the safety and stability, and there is no need to worry about the risk of sagging. Specifically, in this embodiment, the bottom plate 1 is provided with a third guiding groove 11, and a slidable slider is arranged on the third guiding groove 11. The second load-bearing plate 22 is hinged to the slider, so that when the window sash is opened or closed relative to the window frame, the second load-bearing plate 22 can reciprocate along the slider of the bottom plate 1 to smoothly open or close.

[0044] This embodiment also provides the working principle of an externally opened and downwardly suspended hinge 100 with a specific structure, as Figures 1 to 4 shown, among which, as Figure 4 shown, it is specified that the side of the lower cantilever 5 close to the user is the right side, the opposite side is the left side, the side close to the bottom plate 1 is the front, and the side far from the bottom plate 1 is the rear:

[0045] When the window sash is opened: An external force acts on the window sash, driving the short arm 4 to rotate and open, thereby causing the sliding member 61 to slide forward. At this time, the stopper 62 slides out of the second guide groove 612 of the sliding member 61 until the stopper 62 abuts against the first acting member 632. When the stopper 62 abuts against the first acting member 632, it can drive the rotating member 63 to rotate to the left until it stops at the limit position, so as to drive the engaging member 631 to rotate from the initial state where it is staggered from the stopper 62 to the front of the stopper 62. At this time, the sliding member 61 retreats a certain distance to drive the engaging member 631 to move backward until it hovers at the stopper 62. At this time, the stopper 62 prevents the engaging member 631 from moving backward further. By preventing the engaging member 631 from moving backward, the stopper 62 also prevents the sliding member 61 from moving backward, thereby enabling the window sash to complete the fixed and suspended opening action. At this time, the rotating member 63 can rotate to the right under its own inertia to return to the original state.

[0046] When the window sash needs to be closed: An external force acts on the window sash, causing the sliding member 61 to slide forward a certain distance, so that the engaging member 631 is disengaged from the stopper 62. At this time, the stopper 62 switches to abut against and friction with the second acting member 611, causing the stopper 62 to slide to the right along the first guide groove 51. At this time, the rotating member 63 can also rotate to the left under the action of the stopper 62 synchronously, so that the position of the stopper 62 is staggered from the engaging member 631, and the stopper 62 no longer prevents the engaging member 631 from moving backward. At this time, the sliding member 61 can move backward to achieve reset. At the same time, the rotating member 63 can rotate to the right under its own inertia to return to the original state, and the closing of the suspended opening is completed.
