Description

Technical Field

[0001] The utility model relates to the technical field of door and window accessories, in particular to a top and bottom hinge and a casement door and window. Background Art

[0002] A floor hinge is a type of hinge that, unlike traditional hinges, allows doors to open up to 180 degrees, allowing for a wider opening angle. Therefore, it is becoming increasingly popular in the home improvement market. Modern doors and windows are generally manufactured in factories based on the dimensions of the door opening, with the door body and door frame then transported to the site for installation. Due to measurement errors, manufacturing errors, installation errors, and insufficient wall or floor flatness, errors are inevitable during on-site installation. For example, the gap between the top surface of the door body and the lintel may be uneven or interfere with each other. In this case, the door body must be dismantled and reprocessed to remove the interfering parts or by adding gaskets to the hinges to ensure a perfect installation of the door body in the door frame. This results in low installation efficiency and inconvenient adjustment.

[0003] The technical problem to be solved by the utility model is: how to solve the problems of low installation efficiency and inconvenient adjustment of existing doors and windows. Utility Model Content

The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0037] See also Figures 1 to 4, which is a preferred embodiment of the present invention, a top and bottom hinge 100, including a lower hinge assembly 10 and an upper hinge assembly 20; the lower hinge assembly 10 includes a first frame connecting member 11, a first fan connecting member 12, a first rotating shaft 13 and an adjusting member 14, the first frame connecting member 11 and the first fan connecting frame are rotatably connected through the first rotating shaft 13, a first shaft hole 121 is provided on the first fan connecting member 12, one end of the first rotating shaft 13 is connected to the first frame connecting member 11, and the other end is passed through the first shaft hole 121, the first fan connecting member 12 is also provided with an adjusting hole 122 threadedly matched with the adjusting member 14, the adjusting hole 122 is connected to the first shaft hole 121, and the bottom of the adjusting member 14 is opposite to the top of the first rotating shaft 13; the upper hinge assembly 20 includes a second frame connecting member 21 and a second fan connecting member 22 rotatably connected to the second frame connecting member 21.

[0038] The top and bottom hinge 100 of the present application is provided with an adjusting member 14. After the doors and windows are installed, if the gap between the door lintel and the top of the door leaf is too large, the height of the door leaf can be adjusted by screwing the adjusting member 14 into the adjusting hole 122. When the bottom of the adjusting member 14 contacts the top of the first rotating shaft 13, the adjusting member 14 can be continued to be screwed into or out of the adjusting hole 122 to lift or lower the door leaf, thereby adjusting the gap between the door lintel and the top of the door leaf. There is no need to disassemble the door leaf for adjustment, which is convenient for adjustment and improves the efficiency of door and window installation.

[0039] Preferably, the adjusting member 14 is coaxially arranged with the first rotating shaft 13. In other embodiments, the adjusting member 14 can be arranged parallel to or nearly parallel to the first rotating shaft 13. In some cases, when the adjusting member 14 cannot be arranged parallel to the first rotating shaft 13, the adjusting member 14 can be arranged at an angle to the first rotating shaft 13. However, when the adjusting member 14 is arranged at an angle to the first rotating shaft 13, the angle between the adjusting member 14 and the first rotating shaft 13 should be an acute angle. In order to adjust the distance between the first fan connector 12 and the first frame connector 11 by adjusting the screw-in depth of the adjusting member 14, it should be ensured that all or part of the bottom of the adjusting member 14 contacts the top of the first rotating shaft 13 during adjustment. Correspondingly, the bottom of the adjusting hole 122 should be connected to the top of the first shaft hole 121.

[0040] In one embodiment, the first frame connector 11 is provided with a second shaft hole 111 corresponding to the first shaft 13. The second shaft hole 111 is also provided on the end of the first shaft 13 distal from the first sash connector 12. The first shaft 13, the first frame connector 11, and the first sash connector 12 are all separate components. They can be manufactured separately and then assembled later, which optimizes the production process and reduces costs by using universal components. In other embodiments, the first shaft 13 and the first frame connector 11 can be integrally formed, thereby reducing the number of components and simplifying the assembly process.

[0041] Preferably, the lower hinge assembly 10 further includes a bearing 15 sleeved on the first rotating shaft 13, and a receiving groove 16 for accommodating the bearing 15 is provided on the first frame connector 11 and / or the first leaf connector 12. Providing the bearing 15 on the first rotating shaft 13 reduces resistance to rotation of the first leaf connector 12 relative to the first frame connector 11, thereby enabling smoother and quieter opening and closing of the door. In other embodiments, the bearing 15 may not be provided, and rotational engagement may be achieved directly through the first rotating shaft 13 and the first and second shaft holes 121 and 111.

[0042] like Figure 3 As shown, a retaining ring 131 may also be provided on the first rotating shaft 13, positioned between the first frame connector 11 and the first sash connector 12. Providing the retaining ring 131 on the first rotating shaft 13 prevents direct contact between the first sash connector 12 and the first frame connector 11, thereby reducing friction. To prevent the retaining ring 131 from sinking into the first shaft hole 121 or the second shaft hole 111, the outer diameter of the retaining ring 131 should be larger than the diameter of the first shaft hole 121 or the second shaft hole 111.

[0043] In one embodiment, the lower hinge assembly 10 may further include a locking member 17, which extends from a side of the first sash connector 12 into the adjustment hole 122 and is threadedly connected to the first sash connector 12. The locking member 17 can lock the position of the adjustment member 14, preventing the adjustment member 14 from changing in depth in the adjustment hole 122 after the door or window has been used for a long time, thereby affecting the gap between the door sash and the door lintel.

[0044] As a further improvement of the above embodiment, in order to prevent the locking member from damaging the threads on the adjusting member 14, a pad with lower hardness, such as a pad made of plastic, copper, aluminum, etc., can be provided at the bottom of the locking member.

[0045] Optionally, a supporting flange 123 is provided at one end of the first sash connector 12 near the first frame connector 11. The supporting flange 123 supports the sash body 20a when the first sash connector 12 is installed on the sash body 20a, preventing the sash body 20a from contacting the first frame connector 11, thereby reducing noise and extending service life.

[0046] To facilitate the screwing of the adjusting member 14, an operating slot 124 is provided on the first sash connector 12. The bottom of the operating slot 124 communicates with the adjusting hole 122, and the side of the operating slot 124 communicates with the outside. The operating slot 124 facilitates inserting a tool into the adjusting hole 122 to adjust the screwing depth of the adjusting member 14 when adjusting the door leaf height, preventing interference between the first sash connector 12 and the tool.

[0047] Optionally, the second frame connector 21 is configured to be rotatably connected to the second sash connector 22 via a second rotating shaft 23. A third shaft hole 24 corresponding to the second rotating shaft 23 is formed in the second frame connector 21 and / or the second sash connector 22. By providing the third shaft hole 24 in the second frame connector 21 and / or the second sash connector 22, the position of the second rotating shaft 23 can be adjusted synchronously with the adjustment member 14 when the screwing depth is adjusted, thereby preventing the upper hinge assembly 20 from hindering the adjustment of the door leaf height.

[0049] In this embodiment, the first frame connector 11 is locked to the side of the frame body 10a by Zigong screws, and a first mounting groove corresponding to the first fan connector 12 and the second fan connector 22 is provided on the side of the fan body 20a, so that the positions of the first fan connector 12 and the second fan connector 22 can be easily adjusted. The first fan connector 12 and the second fan connector 22 are locked in the first mounting groove by headless screws, and a second mounting groove corresponding to the second frame connector 21 is provided at the top of the frame body 10a. Similarly, the second frame connector 21 is locked in the second mounting groove by headless screws.

[0050] In other embodiments, the first fan connector 12 , the second fan connector 22 and the second frame connector 21 may also be directly fixed by self-tapping screws.

[0051] Optionally, the fan body 20a is provided with a cover plate 21a for covering the sky and earth hinge 100. By providing the cover plate 21a, the sky and earth hinge 100 can be prevented from being exposed, making the door and window more beautiful.

[0052] When adjusting the gap between the top of the fan body 20a and the frame 10a, first loosen the headless screw that locks the second fan connecting member 22, then use a tool to screw the adjusting member 14 into the adjusting hole 122 to the depth according to the size of the gap. When the gap between the top of the fan body 20a and the frame 10a is adjusted to an appropriate range, tighten the locking member 17 to support the adjusting member 14, then re-tighten the headless screw on the second fan connecting member 22, and finally cover the cover plate 21a to complete the adjustment.

[0053] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents.
