Description

Technical Field

[0001] The utility model relates to the technical field of hinges, in particular to door and window hinges, and in particular to a hinge structure for doors and windows to be opened and closed at large angles. Background Art

[0002] Hinges are the main accessories for door and window hinges and are indispensable in the installation of door and window hinges. Common hinges are provided with sub-hinges and main hinges, and the sub-hinges and the main hinges are rotatably connected by a rotating shaft. Since the hinges connect the door and window frames and the door and window panels, the door and window frames and the door and window panels are rotatably connected. To ensure aesthetics, the hinges are hidden when the door and window panels are closed relative to the door and window frames. In order to enable the door and window panels to open and close at a large angle, the rotating connection between the sub-hinges and the main hinges needs to be set close to the wall corners or the corners of the door and window frames, which greatly limits the installation position when the doors and windows are opened and closed at a large angle.

[0003] Some, such as authorization announcement number CN113585900B, provide a concealed hinge that can be opened and closed sequentially at a large angle, including a frame hinge box, an articulated arm and a sash hinge box. The articulated arm rotates to connect the frame hinge box and the sash hinge box. The frame hinge box is fixed in the frame space formed in the door and window frame. The articulated arm extends out of the door and window frame. The sash hinge box located outside the door and window frame can be fixedly connected to the door and window panels.

[0004] However, because the articulated arm rotates the connecting frame hinge box and the sash hinge box at the same time, there are two rotation variables when the door and window panels are rotated to open or close, which makes the movement of rotating the door and window panels feel awkward, that is, different from the feel of conventional rotation operations, affecting the experience of opening and closing the door and window panels.

[0032] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0033] It should be noted that like reference numerals denote like items in the following drawings, and thus, once an item is defined in one drawing, it may not be further defined or explained in subsequent drawings.

[0034] This embodiment mainly describes a hinge structure for doors and windows that is not limited by the installation position and has only one rotation variable and can be opened and closed at a large angle. The details are as follows:

[0035] Example 1

[0036] like Figure 1-7 As shown, the hinge structure for doors and windows to open and close at a large angle includes a door frame panel bracket 2 fixedly installed in the door and window frame 1 by screws (the drawings in the specification only show the door and window frame 1 connected to the hinge on one side, and the door and window frame 1 locked with the door and window panel 4 on the other side is not shown), and a hinged door frame piece 3 rotatably connected to the door frame panel bracket 2 and fixedly connected to the door and window panel 4. The hinged door frame piece 3 includes a rotating part 3a and a fixed part 3b fixedly connected by screws. The rotating part 3a is rotatably connected to the door frame panel bracket 2, and the fixed part 3b is exposed outside the door and window frame 1 and fixedly connected to the door and window panel 4.

[0038] The fixing member 3b has an L-shaped structure, and is provided with a side wall 1 3b1 and a side wall 2 3b2 on the fixing member 3b. The side wall 1 3b1 is connected to one end of the side wall 2 3b2, and the side wall 1 3b1 of the fixing member 3b fits the long portion 3a4 of the rotating member 3a and is fixedly connected by a number of screws and nuts. The side wall 2 3b2 of the fixing member 3b is fixedly connected to the door and window panel 4. In order to reduce the force on the screws connecting the side wall 1 3b1 and the long portion 3a4, a limiting edge 3b3 is provided at the lower end or the upper and lower ends of the side wall 1 3b1. The long portion 3a4 of the rotating member 3a is located between the two limiting edges 3b3. The limiting edge 3b3 supports the long portion 3a4 of the rotating member 3a.

[0039] An opening 11 is provided on the end surface of the door and window frame 1 facing the door and window plate 4, that is, the opening 11 is provided on the side surface of the door and window frame 1, the opening 11 is connected to the interior of the door and window frame 1, the long portion 3a4 of the rotating part 3a can extend the opening 11, and the side wall 3b1 of the fixing part 3b is inserted into the opening 11 and fixedly connected to the long portion 3a4 of the rotating part 3a.

[0040] Preferably, the rotating part 3a and the fixed part 3b can be formed by bending sheet metal, the short part 3a2 and the rotating part 3a1 are tangentially connected, and the connecting part 3a3 and the long part 3a4 are connected at an oblique angle or arc angle, and the length of the long part 3a4 is greater than that of the short part 3a2.

[0041] When the door and window panel 4 is in a closed state, the door and window panel 4 can cover the opening 11 on the door and window frame 1, and when the door and window panel 4 is rotated open by the hinge door frame 3, the opening 11 can effectively avoid the structure on the hinge door frame 3 to avoid rotation interference.

[0042] In this application, the structural setting of the hinged door frame piece 3 is used to enable the hinge to be rotated more than 90° on the door and window frame 1 without being restricted by the installation position, thereby realizing large-angle opening and closing of the door and window panels 4; at the same time, the hinged door frame piece 3 used to fix the door and window panels 4 has only one rotation variable, so that the rotation operation of the door and window panels 4 is conventional, effectively improving the experience of the opening and closing operation of the door and window panels 4.

[0046] In this embodiment, the fixing portion 53 and the fitting portion 54 of the door frame fixing base box 5 are connected by an oblique angle or an arc angle, so that a gap is formed between the fixing portion 53 and the fixing plate 21. When the screws are fixedly connected to the fixing portion 53, the fixing plate 21 and the frame wall of the door and window frame 1, the fixing portion 53 or the oblique angle or the arc angle will be deformed, thereby reducing the distance between the fixing portion 53 and the fixing plate 21, thereby enhancing the stability of the door frame fixing base box 5 during fixed installation.

[0047] In order to enhance the strength of the door frame fixed bottom box 5, that is, to reduce the probability of the two baffles 51 being deformed due to the gravity of the door frame panel bracket 2, the hinged door frame plate 3 and the door and window plate 4, a reinforcing rib 55 is also connected between the two baffles 51, and a box opening 56 is formed between the reinforcing rib 55, the box wall 52 and the two baffles 51. The box opening 56 is opened toward the mouth 11 of the door and window frame 1, and the door frame fixed bottom box 5 is inserted from the box opening 56 and is located between the two baffles 51. Preferably, the maximum rotation angle of the door and window plate 4 when it is opened can be limited by the reinforcing rib 55 or the side wall of the mouth 11 or the outer wall of the door and window frame 1.

[0048] Example 2

[0049] The distinguishing feature from Example 1 is that the hinged door frame piece 3 is integrally formed, and the hinged door frame piece 3 is provided with a rotating portion 3a1 rotatably connected to the door frame panel bracket 2, a short portion 3a2 connected to the rotating portion 3a1, a long portion 3a4 away from the short portion 3a2, a connecting portion 3a3 connecting and spacing the short portion 3a2 and the long portion 3a4, and a fixing portion 53 connected to the connecting portion 3a3 and capable of being fixedly connected to the door and window panel 4 by accessories such as screws. Here, the connected fixing portion 53 and the long portion 3a4 form an L-shaped structure.
