[0039] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose, the present invention is described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0040] like Figure 1As shown, the lower hinge assembly 10 for a window according to an embodiment of the present invention includes: a first fixing member 110 , a second fixing member 120 , a first hinge 131 , a second hinge 132 and a third hinge 133 .

[0041] The first fixing member 110 is installed on the window frame, and the second fixing member 120 is installed on the window sash. The first fixing member 110 is provided with a slide groove 111. Figure 1 As shown, the slide groove 111 extends along the length direction of the first fixing member 110 .

[0042] The first end of the first hinge 131 is hinged to the first fixing member 110, and the second end is hinged to the second fixing member 120; the first end of the second hinge 132 is slidably matched with the slide groove 111 through the slider 160, and the second end is hinged to the first end of the third hinge 133, and the second end of the third hinge 133 is hinged to the second fixing member 120.

[0043] The adjusting member 150 is disposed on the first fixing member 110 , and the opening angle of the window sash can be adjusted by adjusting the length of the adjusting member 150 in the sliding groove 111 .

[0044] When the first fixing member 110 and the second fixing member 120 are respectively installed to the window frame and the window sash, the window sash can be opened and closed through the movement between the first hinge 131 , the second hinge 132 and the third hinge 133 .

[0045] It should be noted that Figure 1 The position of the adjusting member 150 shown in the figure is for the purpose of showing the positional relationship and structural form of the adjusting member 150. In actual use, the adjusting member 150 will move to a position parallel to the first fixing member 110, such as Figure 5 At this time, the adjusting member 150 will at least extend into the slide groove 111 to limit the movable range of the slider 160 in the slide groove 111, thereby limiting the opening and closing angle of the window sash. By adjusting the length of the adjusting member 150 extending into the slide groove 111, the maximum opening and closing angle of the window sash is limited.

[0046] According to the lower hinge assembly 10 for windows of the embodiment of the utility model, the maximum opening angle of the window sash can be limited by the adjusting member 150. Moreover, the length of the adjusting member 150 in the slide groove 111 can be adjusted. Therefore, the length of the adjusting member 150 in the slide groove 111 can be adjusted according to the actual use environment of the window sash, so as to achieve the limit adjustment of any maximum opening angle of the window sash and prevent the window sash from hitting the adjacent obstacles. Moreover, the structure is simple, the installation is more convenient, the use is more comfortable and convenient, and the work efficiency is improved. Moreover, there is no need to install plastic suction cups on the door and window handles, which saves costs and is environmentally friendly and has good practical use value.

[0047] According to some embodiments of the present invention, Figure 1 As shown, the adjusting member 150 is connected to the first fixing member 110 through the fixing assembly 170. Figure 2 and Figure 3 As shown, the adjusting member 150 has an adjusting slot 151. Figure 1 and Figure 5 As shown, the fixing assembly 170 includes a threaded member 171 passing through the adjustment slot 151. That is, the adjustment member 150 can be fixed to the first fixing member 110 by the threaded member 171 (such as a bolt). By loosening the threaded member 171, the adjustment member 150 can be put into an active state, and the position of the adjustment member 150 can be adjusted. When the adjustment member 150 is adjusted to a preset position, the adjustment member 150 can be locked and fixed by tightening the threaded member 171.

[0048] In some embodiments of the present invention, Figure 1 and Figure 5 As shown, the fixing assembly 170 further includes: a clamping piece 172, and a threaded member 171 fixes the clamping piece 172 and the adjusting member 150 to the first fixing member 110. It can be understood that by providing the clamping piece 172, the stability and reliability of the fixing of the adjusting member 150 can be improved. In actual use, the adjusting member 150 is installed on the lower surface of the first fixing member 110, the clamping piece 172 is located on the lower surface of the adjusting member 150, and the threaded member 171 passes through the clamping piece 172 and the adjusting member 150 to fix the adjusting member 150 to the first fixing member 110.

[0049] According to some embodiments of the present invention, Figure 4 and Figure 5 As shown, the adjusting member 150 is provided with a positioning column 152, and the positioning column 152 and the clamping piece 172 are stopped and limited. Figure 5 As shown, when the adjusting member 150 is adjusted to the preset position, the positioning column 152 on the adjusting member 150 abuts against the clamping plate 172, which can effectively avoid the problem that the slider 160 impacts the adjusting member 150 multiple times and causes the position of the adjusting member 150 to change, thereby improving the stability of the maximum preset opening angle of the window sash.

[0050] In some embodiments of the present invention, Figure 2 and Figure 3As shown, the adjustment groove 151 is in the shape of a runway, and the local inner wall of the adjustment groove 151 is recessed to form a toggle groove 154. It should be noted that since the screw member 171 that fixes the adjustment member 150 is usually cylindrical, the adjustment groove 151 with a runway-shaped design can have good adaptability with the screw member 171, so as to better protect the surface of the screw member 171 and increase the service life of the screw member 171. During use, since the adjustment member 150 is located at the bottom of the first fixing member 110, it is difficult to adjust the position of the adjustment member 150. By providing the toggle groove 154, the position of the adjustment member 150 can be adjusted by inserting a screwdriver or other tools into the toggle groove 154.

[0051] According to some embodiments of the present invention, Figure 4 As shown, the end of the adjusting member 150 is provided with a limiting portion 153 extending toward the inside of the slide groove 111. It is understandable that by providing the limiting portion 153, the adjusting member 150 can be effectively limited from sliding along the direction of the slide groove 111, thereby preventing the adjusting member 150 from falling off from the slide groove 111. In the actual processing process, a bending groove can be processed at the end of the adjusting member 150, and a portion of the end of the adjusting member 150 can be pressed and bent to form the limiting portion 153. The design of the bending groove will not break or burr when bending, thereby reducing the scratching of the adjusting member 150 when sliding in the slide groove 111. For example, a limiting portion 150 that is folded upward by 1.5 mm in height and folded at an angle of 90 degrees can be designed at the end of the adjusting member 150, thereby preventing the adjusting member 150 from falling off when sliding in the slide groove 111.

[0052] The width of the adjusting member 150 is designed to be able to slide in the slot of the window frame, and the length can be designed to be able to adjust from 90 degrees to 180 degrees. Of course, it can also be designed to be able to adjust from 0 degrees to 180 degrees. Figure 6 As shown, the invisible inward opening and inward tilting system 100 according to the embodiment of the utility model comprises: an upper hinge assembly 20, a lower hinge assembly 10, a back angler 30, a plurality of transmission bars 40, a side piece 50, an anti-misoperation angle 60, a lock box 70, an anti-dropping device 80, a flip support 90, and a support block 91. Among them, the lower hinge assembly 10 adopts the lower hinge assembly 10 for windows as described above.

[0053] like Figure 6 As shown, the front end of the upper hinge assembly 20 is connected to the transmission bar 40, and then connected to the anti-misoperation corner 60, and then connected to the transmission bar 40, and then connected to the lock box 70, and then connected to the transmission bar 40, and then connected to the flip support 90, and then connected to the anti-drop device 80 and the support block 91. The rear end of the upper hinge assembly 20 is connected to the back corner device 30, and then connected to the transmission bar 40, and then connected to the side member 50. The lower hinge assembly 10 is placed below the rear end of the upper hinge assembly 20 during installation.

[0054] According to the invisible inward opening and tilting member system 100 of the embodiment of the utility model, the lower hinge assembly 10 is provided with an adjusting member 150 which can arbitrarily adjust the maximum opening and closing angle of the window sash, thereby improving the convenience and practicality of using the invisible inward opening and tilting member system.

[0055] According to some embodiments of the present invention, Figure 8-Figure 11 As shown, the end of the anti-dropping device 80 is provided with an easy-to-break groove 801.

[0056] It should be noted that the anti-dropping device 80 and the flip support member 90 of the invisible inward opening and inward tilting member system 100 can realize the inward tilting and opening of the window sash. Figure 7 In actual use, if the window sash is opened and closed for a long time, the window sash may drive the flip support position to move downward under the action of the window sash's gravity, causing the anti-drop device 80 and the flip support member 90 to fail to match accurately.

[0057] In view of the above problems, the existing door and window anti-drop devices on the market do not have easy-to-break grooves at both ends, and when cutting is required, saw blades are used for cutting, which is power-consuming and labor-intensive.

[0058] The utility model provides an easy-to-break groove 801 at the end of the anti-dropping device 80, so that the end of the anti-dropping device 80 can be easily broken off, thereby shortening the distance between the anti-dropping device 80 and the bottom support block 91, and realizing the adjustment of the configuration position between the anti-dropping device 80 and the flip support member 90. In addition, it saves electricity and labor costs. In some embodiments of the utility model, such as Figure 8-Figure 11 As shown, the easy-to-break grooves 801 are multiple and spaced apart. It is understandable that by providing multiple easy-to-break grooves 801, the adjustable range of the height of the anti-dropping device 80 can be increased. In actual use, according to actual needs, it can be broken off from the easy-to-break grooves 801 at the corresponding position. For example, when the door and window sash sags, it is necessary to cut the lower end of the anti-dropping device 80. At this time, according to the size of the cut, it can be cut from the corresponding easy-to-break groove 801 with pliers.

[0059] According to some embodiments of the present invention, Figure 8-Figure 11 As shown, the anti-dropping device 80 is an axisymmetric structural member. Since the anti-dropping device 80 can be arranged on the left and right sides of the window frame, the anti-dropping device 80 is arranged as an axisymmetric structural member. The installation of the anti-dropping device 80 on the left and right sides only requires flipping the anti-dropping device 80. The symmetrical structural member can improve processing efficiency and reduce production costs.

[0060] like Figure 8-Figure 11 As shown, the anti-dropping device 80 of the present invention is designed as a symmetrical rectangle, which is beautiful from a viewing angle and can be placed on the left or right side of the window frame.

[0061] The anti-dropping device 80 is provided with a protrusion 803 in the middle, which is a lock when the window sash is closed, and can play a role in preventing the window sash from falling when it tilts inward. The anti-dropping device 80 is also provided with a reinforcing rib to make the window sash more secure when fixed and improve the structural strength.

[0062] Through the description of the specific implementation methods, a deeper and more specific understanding of the technical means and effects adopted by the present invention to achieve the predetermined purpose should be obtained. However, the accompanying drawings are only for reference and illustration purposes and are not used to limit the present invention.
