Description

Technical Field

[0001] This utility model relates to the field of building decoration technology, and in particular to a concealed hinge support device for glass curtain walls. Background Technology

[0002] In modern architecture, glass curtain walls have become an indispensable and important component of public buildings, especially high-rise buildings, serving as a crucial medium for showcasing architectural facades and visual effects. The operable windows of glass curtain walls mainly fall into two categories: friction hinges and hook-type windows. Friction hinges connect the frame and the operable window via friction hinges (such as four-bar or five-bar linkages), supplemented by limiting mechanisms to achieve opening. This friction hinge connection method uses hinges to function as both hinges and supports, ensuring the airtightness of the operable window while controlling the opening angle, thus guaranteeing personal safety, and offering relatively high cost-effectiveness. Hook-type windows connect the frame to hook-type aluminum profiles, further enhanced by limiting mechanisms to achieve top-hung opening. This opening method significantly enhances the load-bearing capacity of the glass curtain wall.

[0003] Today, the requirements for the appearance of glass curtain walls of buildings are getting higher and higher. As traditional glass curtain walls age and the opening and closing of operable windows are frequently performed, the connecting screws and supports may gradually loosen, the hinges are prone to aging, and water leakage and rust may occur. Moreover, it is difficult to meet the ventilation requirements of modern building curtain walls as well as the aesthetic requirements of building appearance.

[0004] Therefore, there is a need for a concealed hinge that can be applied to glass curtain walls and has a long service life. Utility Model Content

[0030] Currently, in pursuit of aesthetically pleasing effects such as transparency, buildings require increasingly larger glass curtain wall panels, leading to ever-growing operable windows. The excessive weight of these large operable windows poses a significant safety hazard, second only to the spontaneous breakage of tempered glass, making them a serious threat to people's lives. The most common operable windows in glass curtain walls are outward-opening and top-hung designs, primarily implemented using friction hinges and hook-type hinges. Early operable windows typically used friction hinges, which prevented them from being blown off in strong winds even when unlocked. However, as window sizes increased, hook-type hinges were gradually adopted; however, hook-type hinges are prone to being blown off in strong winds.

[0031] Based on this, the present invention is based on a friction hinge, such as... Figures 1-3As shown, a concealed hinge support device 1000 for glass curtain walls is proposed, comprising: a fixed plate 100, which is fixedly connected to the curtain wall frame, and a sliding groove 110 is provided on the fixed plate 100, the extension direction of the sliding groove 110 being at an angle to the length direction of the fixed plate 100; a first hinge component 200, which includes a first hinge arm 210 and a sliding member 220, the sliding member 220 being disposed on one end of the first hinge arm 210 near the fixed plate 100, the sliding member 220 being slidably connected to the sliding groove 110, and the first hinge arm 210 being connected to the fixed plate 100 through the sliding member 220; and a damping rod 300 for damping. One end of the rod 300 is connected to the fixed plate 100, and the other end of the damping rod 300 is connected to the first hinge arm 210; the connector 400 has a through hole and a through groove 410, and the first hinge component 200 is also provided with a first connecting post 230 corresponding to the through groove 410. The first connecting post 230 and the through groove 410 are slidably connected, and the through hole is spaced apart from the through groove 410; the second hinge component 500 includes a second hinge arm 510 and a water-blocking strip 520. The water-blocking strip 520 is disposed on the side of the second hinge arm 510 away from the first hinge arm 210, and the first hinge arm 210 and the second hinge arm 510 are rotatably connected.

[0032] Understandably, when using the concealed hinge support device 1000 for glass curtain walls, two are required when it is installed on the curtain wall frame. The two concealed hinge support devices 1000 for glass curtain walls are set in a mirror image and are respectively set at the left and right ends of the curtain wall frame. They are fixedly connected to the curtain wall frame at the left and right ends by fixing plates 100 respectively set at the left and right ends, and then fixedly connected to the window body of the operable sash by the connectors 400 at the left and right ends, so as to achieve the opening and closing effect of friction hinge.

[0033] In this embodiment, the extension direction of the slide 110 is arc-shaped. A cylindrical sliding member 220 is provided at one end of the first hinge member 200 near the fixed plate 100. The sliding member 220 abuts against the slide 110. When the operator needs to open the opening fan, the opening fan is manually pushed outdoors, and the sliding member 220 moves from the top end of the slide 110 to the bottom end of the slide 110. The damping rod 300 extends as the first hinge member 200 moves, and the damping rod 300 applies resistance during the movement of the first hinge member 200, making it easier for the operator to control the opening angle. The second hinge member 500 includes a second hinge arm 510, which is rotatably connected to the fixed plate 100 through a pivot. The end of the second hinge arm 510 near the pivot is trapezoidal. When the opening fan is opened, the width of the trapezoidal structure of the second hinge arm 510 on the windward side increases, which can avoid stress accumulation at the pivot and enhance the wind resistance effect, thus extending the service life. The water-blocking strip 520 is installed vertically to guide rainwater out and prevent corrosion caused by long-term rainwater retention.

[0034] In one embodiment, the first hinge arm 210 further includes a second connecting post 240, which is disposed on the side of the first hinge arm 210 near the second hinge arm 510. The second hinge arm 510 is provided with a rotating hole corresponding to the second connecting post 240, and the second connecting post 240 passes through the rotating hole and is connected to the second hinge arm 510.

[0035] In this embodiment, the pivot hole provided by the second hinge arm 510 corresponding to the second connecting post 240 is located at one end of the second hinge arm 510 near the connector 400. The first hinge arm 210 and the second hinge arm 510 are connected through the second connecting post 240, so that the side near the fixed plate 100 forms a force-saving lever, which enhances wind resistance and extends service life.

[0036] In one embodiment, the second hinge member 500 further includes a third connecting post 530, which is disposed on one end of the second hinge arm 510 near the fixed plate 100. The third connecting post 530 passes through the through hole, and the second hinge arm 510 is rotatably connected to the connector 400 through the third connecting post 530.

[0037] In this embodiment, the connector 400 has a through hole corresponding to the third connecting post 530. The third connecting post 530 passes through the through hole and is rotatably connected to the through hole. The connection between the third connecting post 530 and the through hole realizes the connection between the second hinge arm 510 and the connector 400. The second hinge arm 510 and the first hinge arm 210 realize the staggered movement of the first hinge arm 210 and the second hinge arm 510 around the second connecting post 240 through the cooperation of the first connecting post 230, the second connecting post 240, the third connecting post 530 and the sliding member 220. This realizes the movement of the connector 400 away from or towards the fixed plate 100 and the adjustment of the angle between the connector 400 and the fixed plate 100, further realizing the opening or closing of the opening fan.

[0038] In one embodiment, the second hinge arm 510 includes a connecting section 511 and an extension section 512. The connecting section 511 and the extension section 512 are connected at an angle. The connecting section 511 is located on the second hinge arm 510 at one end near the fixed plate 100, and the extension section 512 is located on the second hinge arm 510 at one end away from the fixed plate 100. A plurality of water-blocking strips 520 are provided at the connection between the connecting section 511 and the fixed plate. The plurality of water-blocking strips 520 are respectively arranged perpendicular to the extension direction of the extension section 512 or the connecting section 511.

[0039] In this embodiment, the connecting section 511 has a trapezoidal structure, and the extension section 512 has a square structure. The connecting section 511 and the extension section 512 are set at an angle between 120° and 140°, which avoids stress concentration while shortening the space occupied by the second hinge arm 510, improving the concealment effect without affecting mechanical performance. In this embodiment, there are two water-blocking strips 520, both of which are located on the side of the second hinge arm 510 away from the first hinge arm 210, guiding rainwater to flow out in a direction perpendicular to the extension section 512 or the connecting section 511.

[0040] In one embodiment, the second hinge member 500 further includes a damping shaft 540, which is disposed on one end of the second hinge arm 510 near the fixed plate 100, and one end of the damping shaft 540 is rotatably connected to the fixed plate 100.

[0041] In this embodiment, a through hole is provided at one end of the second hinge arm 510 near the fixed plate 100. The damping shaft 540 passes through the through hole and is fixedly mounted on the fixed plate 100. The second hinge arm 510 is connected to the fixed plate 100 through the damping shaft 540.

[0042] In one embodiment, the first hinge member 200 further includes a reinforcing rib 250, which is disposed on the first hinge arm 210 along the length direction of the first hinge arm 210. The reinforcing rib 250 also has a drainage hole 251, which is disposed in a direction perpendicular to the reinforcing rib 250.

[0043] It is understood that in this embodiment, the two reinforcing ribs 250 are arranged perpendicular to the length direction of the first hinge arm 210, and a horizontal reinforcing rib 250 is also provided between the two reinforcing ribs 250 along the extension direction of the first hinge arm 210. In actual use, the horizontal reinforcing ribs 250 are prone to rainwater accumulation. In this utility model, drainage holes 251 are provided on the horizontal reinforcing ribs 250 to help drain rainwater and prevent rainwater from accumulating and causing rust, thus extending the service life of the glass curtain wall concealed hinge support device 1000.

[0044] In one embodiment, the connector 400 is further provided with a first water-blocking member 420 and a second water-blocking member 430. The first water-blocking member 420 is arranged along the length direction of the connector 400, and the second water-blocking member 430 is arranged perpendicular to the first water-blocking member 420 on the connector 400, and the first water-blocking member 420 and the second water-blocking member 430 are spaced apart.

[0045] In this embodiment, the first water-blocking component 420 is used to prevent rainwater from entering the concealed hinge support device 1000 of the glass curtain wall when the operable sash is open, and the second water-blocking component 430 is used to prevent rainwater from entering the concealed hinge support device 1000 of the glass curtain wall when the operable sash is closed. In this embodiment, the first water-blocking component 420 and the second water-blocking component 430 are fixedly connected to the connecting component 400 to prevent water leakage and rust.

[0046] This utility model discloses a concealed hinge support device for glass curtain walls. It utilizes a friction hinge composed of a first hinge component and a second hinge component, both of which are fixedly mounted on a fixed plate. The other end of each hinge component is connected to a connector, reducing the space occupied by the friction hinge and achieving a concealed effect. Simultaneously, a damping rod and a damping pivot provide damping to the first and second hinge components during opening and closing, allowing operators to accurately control the opening angle and extend the service life of the operable windows. Furthermore, the structure of the first and second hinge components enhances wind resistance, reducing the risk of operable windows falling from the glass curtain wall.

[0047] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model.
