Description

Technical Field

[0001] This invention relates to the field of building door and window hardware, and is particularly applicable to large top-hung window hinge structures, specifically an eight-link super-load-bearing top-hung window hinge with a split-angle damping indication function. Background Technology

[0002] Currently, heavy-duty top-hung windows generally use sliding hinges, such as the multi-functional sliding hinge and steering angle disclosed in application number 202410098166.5 for outward-opening top-hung windows. At present, the hinges of top-hung windows still have the following key problems: 1. The linkage supports heavy-duty top-hung windows are prone to deformation and tilting, which causes the top-hung window to slide from the closed position to a dangerous angle due to its own weight and vibration, or to close automatically due to its own weight, which poses a risk of pinching injury; 2. The angle control is rough: traditional limiting devices (such as elastic positioning buckles) can only achieve full-open / half-open dual-state locking, and cannot provide progressive operation feedback, making it difficult for users to accurately control the opening range of the window sash. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide an eight-link super-load-bearing top-hung window hinge.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: An eight-link super-load-bearing top-hung window hinge, characterized in that it includes a slide rail, a slider, and several supporting cantilever arms. The slider is slidably installed in the slide rail. The slider includes a double-link slider and a single-link slider. A short supporting cantilever arm and a long supporting cantilever arm are respectively hinged to the double-link slider. The other end of the short supporting cantilever arm is hinged to a window frame supporting cantilever arm. A support supporting cantilever arm is hinged to the single-link slider. A hinge seat is provided on the side of the slide rail away from the double-link slider, and a hinge seat is hinged to the hinge seat. The outer support cantilever has a single-link slider located between the double-link slider and the hinge seat. The front end of the outer support cantilever is hinged to the front side of the window support cantilever, and the position of the outer support cantilever near its front end is hinged to the front end of the long support cantilever. The middle part of the outer support cantilever is hinged to the support cantilever. Three reinforcing support cantilever arms are hinged between the long support cantilever and the window support cantilever. A limit member is provided at the end of the slide rail near the double-link slider, and the rear end profile of the window support cantilever matches the limit member.

[0005] A positioning pivot is provided between the long support cantilever and the reinforcing support cantilever. The positioning pivot is fixed on the long support cantilever. The top of the positioning pivot includes a positioning plate. A positioning groove is provided on the lower surface of the positioning plate. A first suction member is fixed above the positioning groove. A receiving groove is provided on the upper surface of the reinforcing support cantilever. A movable positioning member is placed on the receiving groove. A second suction member is provided on the top of the movable positioning member. It can be placed into the positioning groove under the suction of the first suction member. The receiving grooves on the three reinforcing support cantilevers are in different positions on the reinforcing support cantilever.

[0006] Furthermore, the long support cantilever is provided with three reinforcing arm hinge interfaces. The bottom of the reinforcing arm hinge interface extends outward to form a mounting part. The mounting part is provided with several limiting grooves. The positioning shaft also includes a shaft mounting component. The bottom of the shaft mounting component is provided with a mounting plate. The positioning plate is provided with a limiting protrusion that matches the limiting groove. The positioning shaft is inserted into the reinforcing arm hinge interface from bottom to top. The shaft mounting component is provided with a mounting slot. The bottom of the positioning plate is provided with a mounting cover. The mounting cover is provided with a mounting clip that engages with the mounting slot.

[0007] Furthermore, the top of the movable positioning component is a spherical crown-shaped flattened top surface, the lower part of the movable positioning component is cylindrical, and the positioning groove is a cylindrical groove.

[0008] Furthermore, a sleeve is provided on the inner surface of the receiving groove, the bottom of the sleeve does not contact the bottom of the receiving groove, the bottom of the movable positioning member extends outward to form a shock-absorbing wing, and shock-absorbing pads are provided on the upper and lower surfaces of the shock-absorbing wing.

[0009] Furthermore, the short support cantilever protrudes upward at one end near the window support cantilever to form a first protrusion, the window support cantilever above the first protrusion protrudes downward to form a second protrusion, and the reinforcing support cantilever protrudes upward at the position near the window support cantilever to form a third protrusion.

[0010] Furthermore, the center point of the receiving groove on the three reinforced cantilever arms is the same distance from the center of the positioning shaft.

[0011] Furthermore, the lower outer part of the outer cantilever extends downward to form a limiting wall.

[0012] Furthermore, the positioning plate above the positioning groove is provided with an adsorption groove, which is connected to the positioning groove, and the first adsorption component is installed in the adsorption groove.

[0013] The eight-link super-load-bearing top-hung window hinge provided by this invention, compared with traditional sliding hinges, can achieve one or more of the following beneficial effects: 1. It has three reinforced cantilever arms, which can significantly reduce the pressure on a single link, and the weight of the top-hung window is more widely distributed, making the link less prone to deformation and avoiding link tilting due to deformation, thus reducing the risk of the window automatically opening or closing due to its own weight; 2. Three levels of tactile feedback: The three reinforced cantilever arms are equipped with receiving grooves and movable positioning parts in different positions, so that the positioning function can be triggered when the window is opened to different angles, producing a clear sense of resistance to prompt the user of the current opening degree. In the positioning state, it can also reduce the probability of the window automatically closing due to wind; 3. The three receiving grooves are distributed on the three reinforced cantilever arms, which can achieve three levels of tactile feedback without excessively weakening the strength of the reinforced cantilever arms, and the reinforced cantilever arms still have good suspension function.

[0023] The invention will now be further described with reference to the accompanying drawings.

[0024] Example 1: An eight-link super-load-bearing top-hung window hinge includes a slide rail 1, a slider, and several cantilever arms. The slide rail 1 is installed on the bottom edge of the window frame. The slider is slidably installed inside the slide rail 1. The slider includes a double-link slider 11 and a single-link slider 12. A short cantilever arm 3 and a long cantilever arm 4 are respectively hinged to the double-link slider 11. The other end of the short cantilever arm 3 is hinged to a window-connecting cantilever arm 6, which is used to connect to the top-hung window. A support cantilever arm 5 is hinged to the single-link slider 12. A hinge seat 13 is provided on the side of the slide rail 1 away from the double-link slider 11. An outer cantilever arm 2 is hinged to the hinge seat 13. The single-link slider 12 is located between the double-link slider 11 and the hinge seat 13. In this embodiment, the length of the outer cantilever arm 2 is close to that of the slide rail. Half the length of the outer support cantilever 2 is hinged at the front end to the front side of the window support cantilever 6 to provide sufficient installation space for the three reinforcing support cantilever 4. The front end of the window support cantilever 6 is used to connect with the top-hung window. The outer support cantilever 2 is hinged to the front end of the long support cantilever 4 near its front end. The middle part of the outer support cantilever 2 is hinged to the support cantilever 5. Three reinforcing support cantilever 7 are hinged between the long support cantilever 4 and the window support cantilever 6, which can significantly reduce the pressure on a single link. The weight of the top-hung window is more widely distributed, making the link less prone to deformation and preventing the link from tilting due to deformation. This reduces the risk of the window opening or closing automatically due to its own weight. A limiter is provided at the end of the slide rail near the double link slider. The rear end profile of the window support cantilever matches the limiter to limit the window when it is closed.

[0025] Example 2: An improvement on the above example is made. The hinge uses a positioning shaft 8 between the long support cantilever 4 and the reinforcing support cantilever 7. The positioning shaft 8 is fixed to the long support cantilever 4 and will not rotate relative to it. The top of the positioning shaft 8 includes a positioning plate 81, and the lower surface of the positioning plate 81 has a positioning groove 811. A first suction member 812 is fixed above the positioning groove 811. The upper surface of the reinforcing support cantilever 7 has a receiving groove 71, on which a movable positioning member 9 is placed. The top 91 of the movable positioning member has a second suction member. The first suction member 812 and the second suction member can magnetically attract each other. The movable positioning component 9 is inserted into the positioning groove 811. After the first suction component 812 suctions the movable positioning component 9 into the positioning groove 811, it can generate a clear sense of resistance to prompt the user to reach a certain preset opening degree. It can also provide positioning capability and reduce the chance of the window closing automatically due to wind. The receiving grooves 71 on the three reinforcing support arms 7 are in different positions on the reinforcing support arms 7, while the positioning grooves on the three positioning plates are in the same position, thus providing three different positioning opening degrees, increasing the user experience. Furthermore, the three receiving grooves 71 are distributed on the three reinforcing support arms 7, so that while realizing three levels of tactile feedback, the strength of the reinforcing support arms 7 is not excessively weakened, and the reinforcing support arms 7 still have good suspension function.

[0026] Furthermore, the long support cantilever 4 is provided with three reinforcing arm hinge interfaces 41. The bottom of the reinforcing arm hinge interface 41 extends outward to form a mounting part 42. The mounting part 42 is provided with several limiting grooves 43. The positioning shaft 8 also includes a shaft mounting component 82. The bottom of the shaft mounting component 82 is provided with a mounting piece 821. The positioning piece 821 is provided with a limiting protrusion 822 that matches the limiting groove 43. The shaft mounting component 82 is inserted into the reinforcing arm hinge interface 41 from bottom to top. At this time, the limiting protrusion 822 is placed in the limiting groove 43, so that the positioning shaft 8 cannot rotate relative to the long support cantilever 4. The shaft mounting component 82 is provided with a mounting slot 823. The bottom of the positioning plate 81 is provided with a mounting cover 812. The mounting cover 812 is provided with a mounting clip 813 that engages with the mounting slot 823 to prevent the positioning plate 81 from rotating.

[0027] In this embodiment, the top of the rotating shaft mounting component 82 is provided with a fixing protrusion, and the mounting cover 812 is provided with a fixing groove. The top of the rotating shaft mounting component 82 can be placed into the fixing groove by elastic deformation, which can fix the positioning plate.

[0028] Furthermore, the top 91 of the movable positioning component is a spherical crown-shaped flattened top surface. When the user wants to disengage from the positioning state, he pushes the upper window forcefully, and the edge of the positioning groove 811 squeezes the spherical crown-shaped top of the movable positioning component 9, causing the movable positioning component 9 to move downward and disengage from the positioning groove 811 to release the positioning state. The lower part of the movable positioning component 9 is cylindrical, and the positioning groove 71 is a cylindrical groove.

[0029] In one embodiment, a sleeve 711 is provided on the inner surface of the receiving groove 71, and a sleeve protrusion is provided in the middle of the sleeve 711. The sleeve is inserted into the receiving groove 71 by elastic deformation, so that the sleeve protrusion is placed in the groove on the inner side of the receiving groove to fix the sleeve 711. The bottom of the sleeve 711 does not contact the bottom of the receiving groove 71. The bottom of the movable positioning member 9 extends outward to form a shock-absorbing wing 92. The upper and lower surfaces of the shock-absorbing wing are provided with shock-absorbing pads. When entering the positioning state, the shock-absorbing pad 921 above the shock-absorbing wing 92 impacts the sleeve. When leaving the positioning state, the shock-absorbing pad 922 at the bottom of the shock-absorbing wing 92 impacts the receiving groove 71, reducing the sound generated when entering / leaving the positioning state and improving the user experience.

[0030] Furthermore, the short support cantilever 3 protrudes upward at one end near the window support cantilever to form a first protrusion 31, the window support cantilever 6 above the first protrusion 31 protrudes downward to form a second protrusion 61, and the reinforcing support cantilever 7 protrudes upward at the position near the window support cantilever 6 to form a third protrusion 72, providing space for the positioning plate 81 and the outer support cantilever 2 to move.

[0031] In one embodiment, the center point of the receiving groove 71 on the three reinforcing cantilever arms 7 is the same distance from the axis of the positioning shaft 8, and the positioning plates 81 on the three reinforcing cantilever arms 7 have the same shape, reducing production costs.

[0032] Furthermore, the lower outer side of the outer cantilever 2 extends downward to form a limiting wall 21, which can limit the movement when the window is closed.

[0033] In one embodiment, the positioning plate 81 above the positioning groove 811 is provided with an adsorption groove 813, which is connected to the positioning groove 811, which is beneficial for the first adsorption member 812 to adsorb the movable positioning member. The first adsorption member 812 can be glued to the adsorption groove 813.

[0034] The above embodiments are merely preferred embodiments of the present invention and are not intended to limit the technical solutions of the present invention. Any technical solution that can be implemented based on the above embodiments without creative effort should be considered to fall within the scope of protection of the patent of the present invention.
