Description

Technical Field

[0001] This invention belongs to the field of hardware technology, specifically relating to a hinge and a window. Background Technology

[0002] Windows are a fundamental component of modern buildings. Based on their opening method, existing windows can be mainly categorized into casement windows, sliding windows, and awning windows. However, with the continuous improvement of people's living standards, these types of windows no longer meet people's evolving needs; their applicability or ease of use is relatively insufficient. Furthermore, both casement and sliding windows use hinges to allow the window sash to rotate relative to the frame. Specifically, the rotation axis of a casement window is longitudinal, while the rotation axis of an awning window is transverse.

[0003] Casement windows, with their sashes fully openable and large opening area, offer better ventilation and light transmission. However, they also have several drawbacks: 1. An open casement window poses a safety hazard to active young children; 2. When no one is home, an open or left-closed casement window provides a convenient entry point for criminals, offering poor security; 3. Rainwater can easily enter the room during rainy weather. While awning windows effectively overcome the shortcomings of casement windows, they suffer from limited opening angle and a smaller opening area, resulting in relatively poor ventilation. In conclusion, improving the hinges to combine the advantages of both casement and awning windows would better meet diverse and convenient window usage needs, thus enhancing the overall usability of windows.

[0042] The technical solutions of the present application will be further described in detail below with reference to the drawings and specific embodiments, so that those skilled in the art can better understand the present application and implement it. However, the embodiments are not intended to limit the present application. In the embodiments, it should be understood that the terms "longitudinal", "transverse", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer" and the like indicate the orientation or positional relationship shown in the drawings, and are only for the purpose of describing the present application, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as limiting the present application.

[0043] It should be noted that when an element is considered to be "connected" to another element, it can be directly connected to the other element and integrated as a whole, or there can be a middle element. The terms "mount", "one end", "the other end" and the like used in the present application are only for the purpose of illustration.

[0044] As shown in Figures 1-4 The present embodiment provides a hinge, which includes a first mounting seat 1, a second mounting seat 2 and a support arm assembly, the support arm assembly is movably connected with the first mounting seat 1 and the second mounting seat 2 respectively; wherein the first mounting seat 1 is used for mounting a sash 36, and the second mounting seat 2 is used for mounting a window frame 35, that is, the sash 36 and the window frame 35 are movably connected through the hinge, thereby realizing the function of opening or closing the window frame 35 by the sash 36. Further, in the horizontal direction relative to the second mounting seat 2, the first mounting seat 1 can rotate relative to the second mounting seat 2, and the support arm assembly is used to constrain and move the first mounting seat 1 along a predetermined trajectory relative to the second mounting seat 2; in this use state of the hinge, the movement mode of the sash 36 relative to the window frame 35 is flat opening. Alternatively, when the first mounting seat 1 and the second mounting seat 2 are in a folded state, in the longitudinal direction relative to the second mounting seat 2, the first mounting seat 1 and / or the support arm assembly can be inclined relative to the second mounting seat 2, so that the longitudinal axis of the first mounting seat 1 and / or the support arm assembly forms an angle with the longitudinal axis of the second mounting seat 2; in this use state of the hinge, the movement mode of the sash 36 relative to the window frame 35 is suspended opening. That is, by allowing the first mounting seat 1 (used for connecting the sash 36) in the hinge to rotate horizontally relative to the second mounting seat 2 (used for connecting the window frame 35), while also allowing the first mounting seat 1 to be flipped in the longitudinal direction relative to the second mounting seat 2, thereby allowing the sash 36 to be used in a flat opening or suspended opening manner relative to the window frame 35, thereby allowing the window to meet different use requirements; for example, when better ventilation and light transmission effect is needed, the window can be opened in a flat opening manner; and when better safety is needed, the window can be opened in a suspended opening manner.

[0045] As Figures 1-4 shown in the preferred embodiment, the support arm assembly comprises a first support arm 3, a second support arm 4 and a connecting rod 5, one end of the first support arm 3 is rotatably connected with the second mounting base 2 through a hinge pin 18, the other end of the first support arm 3 is rotatably connected with the first end of the connecting rod 5 through a pin, and the second end of the connecting rod 5 is rotatably connected with the first mounting base 1 through a pin. One end of the second support arm 4 is rotatably connected with the second mounting base 2 through a hinge pin 18, and the hinge pin 18 can slide relative to the second mounting base 2, the other end of the second support arm 4 is rotatably connected with the first mounting base 1, and the first support arm 3 is rotatably connected with the second support arm 4 through a pin.

[0046] As Figure 3 shown in the preferred embodiment, in the state that the projection planes of the first mounting base 1 and the second mounting base 2 coincide in the longitudinal direction, that is, the hinge is in the folded state, the support arm assembly can be inclined relative to the second mounting base 2 and the longitudinal axis of the first mounting base 1 forms an angle with the longitudinal axis of the second mounting base 2, that is, the support arm assembly and the first mounting base 1 can both be inclined relative to the second mounting base 2. Specifically, the hinge in this embodiment is a lower hinge, that is, when the overhang function of the window is needed, the cooperation of the upper hinge is also needed; further, in the overhang state, the axis of the sash 36 in the width direction is the rotation fulcrum of the deflection of the sash 36 relative to the window frame 35.

[0047] As Figure 4 shown in the preferred embodiment, the first support arm 3 is provided with a first hinge hole 6, a second hinge hole 7 and a third hinge hole 8 along the length direction thereof, the second support arm 4 is provided with a fourth hinge hole 9, a fifth hinge hole 10 and a sixth hinge hole 11 along the length direction thereof, the first mounting base 1 is provided with a seventh hinge hole 12 and an eighth hinge hole 13 along the length direction thereof, and the second mounting base 2 is provided with a ninth hinge hole 14 and a tenth hinge hole 15 along the length direction thereof.

[0048] Further, the first hinge hole 6 and the ninth hinge hole 14 form a hinge through the hinge pin 18, the second hinge hole 7 and the fifth hinge hole 10 form a hinge, the third hinge hole 8 and one end of the connecting rod 5 form a hinge and form an eleventh hinge point, the fourth hinge hole 9 and the seventh hinge hole 12 form a hinge, or in other words, the fourth hinge hole 9 and the seventh hinge hole 12 form a hinge and form a thirteenth hinge point, the sixth hinge hole 11 and the tenth hinge hole 15 form a hinge through the hinge pin 18, wherein the sixth hinge hole 11 can translate along the length of the tenth hinge hole 15, that is to say, the tenth hinge hole 15 is strip-shaped and extends along the length of the second mounting base 2, that is to say, the hinge pin 18 can slide along the tenth hinge hole 15 or in other words, can slide along the length of the second mounting base 2, the eighth hinge hole 13 is hingedly connected to the other end of the connecting rod 5 and forms a twelfth hinge point.

[0049] Further, the first recess 16 is arranged on one side of the second support arm 4 in the width direction, and when the first mounting seat 1 and the second mounting seat 2 are in the folded state, or in other words, when the sash 36 is closed in the window frame 35 relative to the window, the connecting rod 5 is arranged in the first recess 16. Further, the third hinge hole 8, the eighth hinge hole 13, and the seventh hinge hole 12 form a triangle, or in other words, two hinge holes on the connecting rod 5 and the seventh hinge hole 12 on the first mounting seat 1 together form a triangle, or in other words, the eleventh hinge point, the twelfth hinge point, and the thirteenth hinge point together form a triangle; that is, at this time, because one end of the connecting rod 5 is rotationally connected to the first mounting seat 1, and the other end of the connecting rod 5 is rotationally connected to the first support arm 3, a obtuse triangle is formed. Both of the two angle points in this triangle are on the first mounting seat 1, and at this time (when the window is in the closed state, that is, when the sash 36 is closed in the window frame 35), when the triangle needs to be changed, the third angle point on the connecting rod 5 (when the first support arm 3 is rotated) can be changed, or in other words, the third angle point moves relative to the width direction (left and right) of the window frame 35, or relative to the thickness direction (front and back, or indoor and outdoor) of the window frame 35, wherein the eleventh hinge point moves to the outdoor, and is limited by the first recess 16, further, for an inward opening window, the negative wind pressure on the indoor side acts on the sash 36, at this time, the window hardware bears part of the force (wind pressure), and the other part of the force is transferred to the window frame and then to the wall through the overlapping edge of the sash and the window frame. Further, the eleventh hinge point moves to the indoor side on the premise that the sixth hinge hole 11 moves to one end of the tenth hinge hole 15 on the second mounting seat, but the sixth hinge hole 11 on the second support arm needs to move to one end of the tenth hinge hole 15 on the second mounting seat when the sash is opened to 10 degrees); at this time, because the connecting rod 5 is arranged in the first recess 16, the third angle point cannot move relative to the width direction (left and right) of the window frame 35. Further, the sixth hinge hole 11 on the second support arm 4 is constrained by the tenth hinge hole 15 on the second mounting seat 2, and the first recess 16 (on or towards the indoor side) on the second support arm 4 accommodates the connecting rod 5 at this time, thereby limiting the movement of the hinge point formed by the connecting rod 5 and the third hinge hole 8 to the outdoor direction. Further, the third hinge hole 8, the fifth hinge hole 10, and the first hinge hole 6 form a triangle; when the triangle needs to be changed, the first hinge hole 6 as one angle point is relatively fixed, and thus only the second angle point, that is, the hinge point of the second hinge hole 7 and the fifth hinge hole 10 (which can be regarded as the fourteenth hinge point), and the third angle point, that is, the hinge point of the sixth hinge hole 11 and the tenth hinge hole 15 (which can be regarded as the fifteenth hinge point), can be changed to change the obtuse triangle into an acute triangle. However, the sixth hinge hole 6 on the second support arm 4 needs to move to one end of the tenth hinge hole 15 on the second mounting seat when the sash is opened to 10 degrees.This prevents the hinge point formed by the connecting rod 5 and the third hinge hole 8 from moving inwards. In other words, when the hinge is in the folded state, the first support arm 3, the second support arm 4, and the connecting rod 5 cooperate with each other to form a self-locking mechanism, thereby allowing the closed window sash 36 to withstand positive or negative wind pressure from the outside, thus maintaining the relative airtightness of the window sash 36 relative to the window frame 35.

[0050] like Figures 2-4 As shown, in a preferred embodiment, a second recess 17 is provided on the other side of the second support arm 4 opposite to the first recess 16. When the window sash 36 is opened to 180 degrees relative to the window frame 35 in the casement mode, the corners of the window sash 36 will compress the second support arm 4. The second recess 17 can avoid the corners of the window sash 36, allowing the window to open to 180 degrees, thus providing a larger opening to meet higher usage needs. Furthermore, when the hinge is in the retracted state, the second support arm 4 forms a complete strip, i.e., the notch provided on the second support arm 4 (such as the second recess 17, used to avoid the corners of the window sash 36; the first recess 16, used to accommodate the connecting rod 5) makes the hinge structure relatively more compact. Alternatively, the second support arm 4 is clamped between the first mounting base 1 and the first support arm 3, and the second support arm 4 and the connecting rod 5 are on the same plane, making the hinge structure relatively more compact after retraction.

[0051] like Figure 4As shown, in the preferred embodiment, the ninth hinge hole 14 and the tenth hinge hole 15 are both provided with a hinge pin 18 for forming a hinge between the second mounting base 2 and the first support arm 3 and the second support arm 4 respectively; further, the end of the first end of the hinge pin 18 is provided with a chamfered surface 19, which makes the axis of the hinge pin 18 inclined relative to the axis of the ninth hinge hole 14 or the tenth hinge hole 15. When the first mounting base 1 and the second mounting base 2 are in the folded state, the chamfered surface 19 is located on one side of the second mounting base 2 in the width direction, and can make the first mounting base 1 or the sash 36 inclined (overhung) relative to the window frame 35. The hinge pin 18 in the embodiment is cylindrical, and the curvature of the end of the first end of the hinge pin 18 is convex, which makes the hinge pin 18 inclined relative to the hinge hole, and also prevents the hinge pin 18 from falling out of the hinge hole. Further, in the thickness direction of the hinge, one of the hinge pins 18 is loosely fitted with the second mounting base 2 and the first support arm 3, and the other hinge pin 18 is loosely fitted with the second mounting base 2 and the second support arm 4, that is, one of the hinge pins 18 can slide relative to the second mounting base 2, or the two hinge pins 18 can be inclined at an angle relative to one side of the second mounting base. Further, when the first mounting base 1 is unfolded relative to the second mounting base 2, the arm assembly is also unfolded, that is, at this time the first mounting base 1 is unfolded (rotated) inward relative to the second mounting base 2; further, when the first mounting base 1 and the second mounting base 2 are in the folded state, at this time the first support arm 3 and the second support arm 4 can drive the corresponding hinge pin 18 to move in the thickness direction of the hinge (that is, the hinge pin 18 can be inclined relative to the axis in the thickness direction of the hinge), so that the first support arm 3 and the second support arm 4 are inclined inward or outward relative to the second mounting base 2, and further so that the sash is opened in the inward overhung or outward overhung manner relative to the window frame.

[0052] Further, taking the center line of the ninth hinge hole 14 and the tenth hinge hole 15 as the reference line, when the first mounting base 1 and the second mounting base 2 are in the folded state, the centers of the third hinge hole 8 and the eleventh hinge hole are located on the first side of the reference line, and the centers of the second hinge hole 7 and the fifth hinge hole 10 are located on the second side opposite to the first side of the reference line; further, when the first mounting base 1 is unfolded relative to the second mounting base 2 to 3-10 degrees to the first side, the centers of the second hinge hole 7 and the fifth hinge hole 10 cross the reference line to the first side.

[0053] As Figure 4As shown, in the preferred embodiment, the first mounting base 1 is further provided with a first adjusting mechanism, the first adjusting mechanism is used for adjusting the position of the first mounting base 1 relative to the second mounting base 2; that is, the first adjusting mechanism is used for fine-tuning the front and back positions of the window sash 36 relative to the window frame 35, so as to ensure the safety precision of the window. Specifically, the first adjusting mechanism comprises a shaft sleeve 20, a top screw 21, a first rotating shaft 22 and a second rotating shaft 23, the shaft sleeve 20 is integrally formed with the first mounting base 1, and the shaft sleeve 20 is perpendicular to the first mounting base 1, the first rotating shaft 22 and the second rotating shaft 23 are integrally formed, and the axis of the second rotating shaft 23 deviates from the axis of the first rotating shaft 22, the first rotating shaft 22 is rotationally connected with the shaft sleeve 20, and the first rotating shaft 22 is movable along the axial direction of the shaft sleeve 20, the second rotating shaft 23 is hingedly connected with the second supporting arm 4, the top screw 21 is movably connected with the shaft sleeve 20, and the top screw 21 is used for locking the first rotating shaft 22 in the shaft sleeve 20 in the longitudinal direction. For example, when the window is closed, the frame surface of the window sash 36 cannot be flush with the frame surface of the window frame 35, at this time, the first rotating shaft 22 can be rotated to drive the second rotating shaft 23 to rotate, and since the first rotating shaft 22 and the second rotating shaft are eccentrically arranged, the position of the window sash 36 relative to the window frame 35 can be fine-tuned, and the safety quality of the window can be realized.

[0054] As Figure 4As shown, in the preferred embodiment, the second mounting base 2 is further provided with a reinforcing back plate 24, the reinforcing back plate 24 is arranged along the axial direction of the second mounting base 2, the reinforcing back plate 24 is fixed with the second mounting base 2 by bolts or rivets, and one side of the reinforcing back plate 24 in the width direction is further provided with a first clamping portion 25, the first clamping portion 25 is used to form clamping with the C-shaped groove of the window frame 35, and the reinforcing back plate 24 is further provided with a locking piece 26, the locking piece 26 can rotate relative to the reinforcing back plate 24, and the locking piece 26 and the first clamping portion 25 are matched with each other to form fixation of the reinforcing back plate 24 with the window frame 35. Specifically, when the second mounting base 2 needs to be clamped with the C-shaped groove of the window frame 35, or in other words, the first clamping portion 25 on the second mounting base 2 needs to be clamped with the C-shaped groove of the window frame 35 to increase the connection strength of the second mounting base 2 with the window frame 35 or the C-shaped groove; at this time, since the window frame 35 is a closed ring (quadrilateral) at this time, that is, the second mounting base 2 cannot be inserted into the groove along the axial direction of the C-shaped groove of the window frame 35, therefore the first clamping portion 25 can only be clamped into one side of the groove in the radial direction at a certain angle, that is, relative to the width direction of the C-shaped groove, the first clamping portion 25 can only be clamped with one side of the C-shaped groove, and the other side is in a vacant state, at this time, the locking piece 26 arranged on the reinforcing back plate 24 is rotated and the free end of the locking piece 26 is clamped on the other side of the C-shaped groove, thereby forming fixation of the reinforcing back plate 24 or the second mounting base 2 with the window frame 35. Further, the first clamping portion 25 is integrally formed with the reinforcing back plate 24, so that the reinforcing back plate 24 can bear a larger load, when the flat hinge is applied in the window, and the sash 36 is opened, at this time, the first clamping portion 25 on the reinforcing back plate 24 on the flat hinge at the bottom of the sash 36 can be correspondingly clamped on the innermost side of the C-shaped groove of the window frame 35, that is, the side of the C-shaped groove farthest from the sash 36 (relative to the inner side, the direction in which the sash 36 is opened is the outer side); further, the first clamping portion 25 on the reinforcing back plate 24 on the flat hinge at the top of the sash 36 can be correspondingly clamped on the outermost side of the C-shaped groove of the window frame 35, that is, the side relatively close to the sash 36; that is, at this time, the load on the reinforcing back plate 24 from the gravity of the sash 36 is mainly borne by the first clamping portion 25; in addition to enabling the reinforcing back plate 24 to be clamped with the C-shaped groove of the window frame 35, the locking piece 26 can also apply a transverse thrust to the reinforcing back plate 24 relative to the width direction of the C-shaped groove, that is, the reinforcing back plate 24 cannot move freely relative to the C-shaped groove, that is, the first clamping portion 25 and the edge of the C-shaped groove of the window frame 35 are fully buckled to ensure reliable stress bearing of the reinforcing back plate 24 or the second mounting base 2.

[0055] As Figure 2 , Figure 4As shown, in the preferred embodiment, a receiving groove 27 is provided on the reinforcing back plate 24, and the locking member 26 is located in the receiving groove 27. One end of the locking member 26 is rotatably connected to the reinforcing back plate 24 and / or the second mounting base 2, and the other end of the locking member 26 is a free end. After the locking member 26 is locked with the window frame 35, the free end of the locking member 26 protrudes from the other side of the width direction of the reinforcing back plate 24, and the free end abuts against the window frame 35. The receiving groove 27 can reduce the overall thickness of the hinge, thereby facilitating the installation and fixing of the hinge in the window frame 35. Of course, relative to the thickness direction of the reinforcing back plate 24, the locking member 26 can be slightly higher than the reinforcing back plate. That is, after the second mounting base 2 is locked with the window frame 35, a certain compressive force or pre-tightening force can be formed on the locking member 26 at the same time, so that the locking member 26 will not easily loosen due to factors such as transmitted vibration and wind-induced vibration during the later use of the window.

[0056] like Figure 4 As shown, in a preferred embodiment, a second adjustment mechanism is further included. The second adjustment mechanism is movably connected to the second mounting base 2, and is used to adjust the movement distance of the second mounting base 2 relative to the window frame 35 in the width direction. Specifically, the second adjustment mechanism includes a fixed base 28, an adjusting bolt 29, and an adjusting nut 30. The adjusting nut 30 is detachably engaged with the fixed base 28, the adjusting bolt 29 is rotatably connected to the second mounting base 2, and the adjusting bolt 29 and the adjusting nut 30 are connected by bolts. The fixed base 28 is used to fix the window frame 35. Furthermore, a second latching part 31 is provided on both sides of the fixing seat 28 in the width direction. The second latching part 31 is used to make the fixing seat 28 and the window frame 35 lock together. The length of the fixing seat 28 is less than its width. In other words, the length of the fixing seat 28 is less than the width of the C-shaped groove of the window frame. That is, when the fixing seat 28 needs to be installed in the C-shaped groove of the window frame 35, the fixing seat 28 is first placed in the opening of the C-shaped groove, and then rotated 90 degrees so that the second latching part 31 locks with the edge of the C-shaped groove of the window frame. Furthermore, the fixing seat 28 is also provided with a fixing through hole 32, and a locking member 33 is provided in the fixing through hole 32. The locking member 33 is screwed into the fixing through hole 32. The second buckle part 31 is also provided with a storage groove 34, which corresponds to the fixing hole. The locking member 33 is used to fix the fixing seat 28 to the window frame 35. When the locking member 33 is rotated and the fixing seat 28 is fixed to the window frame 35 profile, the end of the locking member 33 will squeeze and damage the profile (equivalent to drilling a hole in the profile) and generate debris. With the storage groove 34, the generated debris can fall directly into the storage groove 34, thereby avoiding these debris from affecting the adjustment of the hinge, or in other words, affecting the smooth movement of the second mounting seat 2 along the C-shaped groove of the window frame 35.

[0057] like Figures 5-6As shown, the embodiment also provides a window, which comprises a window frame 35, a window sash 36 and the hinge as described above, the window frame 35 is fixedly connected with the second mounting seat 2 of the hinge, and the window sash 36 is fixedly connected with the first mounting seat 1 of the hinge.

[0058] In the width direction relative to the window frame 35, one side of the window sash 36 is a rotating fulcrum and can rotate relative to the window frame 35 to open or close the window frame 35.

[0059] Alternatively, in the height direction relative to the window frame 35, one end of the window sash 36 is a rotating fulcrum and can tilt relative to the window frame 35 to open or close the window frame 35.

[0060] The beneficial effects of the present application relative to the prior art mainly lie in: by enabling the first mounting seat (for connecting the window sash) in the hinge to horizontally rotate relative to the second mounting seat (for connecting the window frame), while also enabling the first mounting seat to overturn relative to the second mounting seat in the longitudinal direction, the window sash can be used in a flat opening or a suspended opening manner relative to the window frame, and the window can meet different use requirements; for example, when better ventilation and light transmission effects are needed, the window can be opened in a flat opening manner; and when better safety is needed, the window can be opened in a suspended opening manner; that is, the convenience or applicability of the hinge and the window is improved.

[0061] In the present specification, unless explicitly specified and limited, a first feature is "on" or "under" a second feature can be that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. Moreover, the first feature "above", "over" and "on" the second feature can be that the first feature is directly above or obliquely above the second feature, or only means that the horizontal height of the first feature is higher than that of the second feature. The first feature "below", "under" and "under" the second feature can be that the first feature is directly below or obliquely below the second feature, or only means that the horizontal height of the first feature is less than that of the second feature.
