Detailed Description
The present invention will be further explained with reference to the accompanying drawings.
As shown in fig. 1 to 2, a casement electric window opening device includes a window frame 10, a window sash 20, a window pushing device 30, and a controller. The window sash 20 is rotatably provided in the window frame 10. The frame mounting rim 11 is opposite to the sash mounting rim 21, and the frame top rim is opposite to the sash top rim. The bottom side frame edge of the window frame is opposite to the bottom side frame edge of the window sash. The top side frame edge and the bottom side frame edge of the window frame are respectively connected with the window frame mounting frame edge 11, and the top side frame edge and the bottom side frame edge of the window sash are respectively connected with the window sash mounting frame edge 21. The frame mounting rim 11 and the sash mounting rim 21 are hinged together such that the sash 20 is rotatably coupled with the window frame 10. One end of the first chain 33 of the window pushing device 30 is connected to the top frame of the window frame, and the other end is connected to the top frame of the window sash. The second chain 34 of the window pushing device 30 has one end connected to the bottom side frame of the window frame and the other end connected to the bottom side frame of the window sash. When the window sash frame is used, the controller controls the first motor 31 and the second motor 32 to simultaneously extend out of the first chain 33 and the second chain 34, so that the two chains 33 and 34 apply pushing force towards the outdoor to the corresponding sash top side frame edge and the sash bottom side frame edge. This allows the window sash 20 to be rotated outward with respect to the window frame 10, and thus the window is opened. The dual motor, dual chain design allows the top and bottom rims of sash 20 to be pushed simultaneously and sash 20 may be pushed open more easily than the single motor, single chain design.
In some embodiments, as shown in fig. 1-3, the present invention also includes a right angle hinge. The window frame 10 and the window sash 20 are hinged together by two pairs of right-angle hinges. Two pairs of right-angle hinges are respectively arranged at the positions of the mounting frame edges 11 and 21 close to the top frame edge and the bottom frame edge of the window frame. The right angle hinge includes a first right angle member 50 and a second right angle member 60. The first right-angle member 50 includes a first fixing piece 51 and a second fixing piece 52 perpendicular to each other, and the right-angle member 60 includes a first mounting piece 61 and a second mounting piece 62 perpendicular to each other. In particular, when installed, the first angled member 50 is open and the second angled member 60 is facing the window frame mounting rim 11. The first fixing piece 51 is opposed to the first attaching piece 61, and the second fixing piece 52 is opposed to the second attaching piece 62. The end of the second fixing piece 52 remote from the first fixing piece 51 and the end of the second mounting piece 62 remote from the first mounting piece 61 are rotatably connected together. The first fixing piece 51 is fixedly provided on the window frame mounting rim 11, and the first mounting piece 61 is fixedly provided on the window sash mounting rim 21. The first fixing piece 51 of the first right-angle member 50 and the first mounting piece 61 of the second right-angle member 60 are located at the frame mounting rim 11 and the sash mounting rim 21. Such a design allows a longer moment arm L to be obtained, so that with the same pushing force F, a greater moment M = F × L is obtained, so that the sash can be pushed open more easily, and at the same time the possibility of deformation of the hinge member, i.e. the second angled member 60, due to the force applied thereto is reduced, so that the sash 20 is more firmly connected to the frame 10.
Referring specifically to fig. 4, fig. 4 (a) is a right-angle hinge according to the present invention for hinge joint and fig. 4 (b) is a flat hinge for hinge joint. When a right-angle hinge is used as a hinge component, the arm of force from the pushing force F to the hinge is L1. And a flat hinge is used as a hinge component, and the arm of the pushing force F to the hinge is L2. When the distance from the pushing force F to the window sash mounting frame edge 21 is the same, the force arm L1 is larger than the force arm L2. Therefore, the right-angle hinge is used, compared with a common flat hinge, the force arm can be increased, so that under the condition of the same thrust F, larger moment is obtained, and the window sash 20 can be pushed away more easily. Secondly, the use of right-angle hinges allows a larger area of glass 40 to be installed, with the same size of window frame 10 and sash 20, for a more aesthetic appearance, particularly for buildings in which integral glass curtain walls are used. Again, when the sash 20 is in the closed position with respect to the frame 10, the sash 20 is surrounded by the frame 10, so that the sash 20 is supported by the frame 10 from below to above, reducing the force applied to the second right-angle member 60, thereby reducing the possibility of deformation of the second right-angle member due to the force applied, and thus providing a more secure connection between the sash 20 and the frame 10.
So when using a right angle hinge as the hinge member, the sash 20 can be pushed open more easily, and at the same time the connection between the sash 20 and the frame 10 is firm and the sash does not easily fall off the frame 10.
In some embodiments, the first chain 33 is mounted at one end to the top side sash edge of the sash frame at a distance L11 from the sash mounting sash edge 11, where L11 is greater than half the length of the top side sash edge of the sash frame. The other end of the first chain 33 is installed on the top frame edge of the window sash, the distance from the first chain to the window sash installation frame edge 21 is L12, and L12 is greater than half of the length of the top frame edge of the window sash. One end of the second chain 34 is mounted on the bottom side frame edge of the window frame, and the distance from the second chain to the window frame mounting frame edge 11 is L21, and L21 is greater than half of the length of the bottom side frame edge of the window frame. The other end of the second chain 34 is installed on the bottom frame edge of the window sash, and the distance from the second chain to the window sash installation frame edge 21 is L22, and L22 is greater than half of the length of the bottom frame edge of the window sash. L11= L21; and L12= L22. Such a design allows the torque M = F × L to be greater for a longer distance L under the same urging force F, so that a smaller urging force F is applied and a greater torque M is generated, so that the sash 20 can be pushed open more easily.
In some embodiments, the controller is coupled to the smoke detector for detecting a smoke condition in the room. When the indoor smoke reaches or exceeds the set value, the controller activates the first motor 31 and the second motor 32 to push the window sash 20 open to discharge smoke. Therefore, when a fire disaster occurs and a large amount of smoke is generated, the window can be automatically opened to discharge the smoke.
In some embodiments, the first chain 33 and the second chain 34 are both hidden toothed chains. When the window sash 20 is closed, the chain is invisible, ensuring a neat and beautiful indoor space.
In some embodiments, the first chain 33 and the second chain 34 are both arc-shaped chains, and the arc-shaped design enables the first chain 33 and the second chain 34 to apply a pushing force perpendicular to the window sash top side frame edge and the window sash bottom side frame edge, so that the window sash can be pushed open more easily than a non-perpendicular pushing force. In some embodiments, sash 20 also includes a bead of sealant.
In some embodiments, window sash 20 is fitted with hollow glass.
In some embodiments, the electric casement window opening device is applied to a building body provided with a glass curtain wall. The installation of the glass curtain wall requires the arrangement of uprights and cross beams fixed to the building body. The posts and beams are perpendicular to each other and the adjacent posts and beams form a rectangular space, and at this time, the window frame 10 is mounted on the posts and beams. The first motor 31 and the second motor 32 are directly fixed to the cross member. When the building body includes a fire fighting control system, the first motor 31 and the second motor 32 are connected to a controller of the fire fighting control system.
