Description

Technical Field

[0001] The invention relates to the technical field of door and window hardware accessories, in particular to a hinge and a door and window assembly. Background Art

[0002] Hinges are a common hardware accessory for doors and windows, primarily used to attach doors and windows to their frames. Currently, conventional hinges employ a fixed position on one side and a sliding motion on the other. However, this unilateral motion results in excessive sliding distance for a single component on one side, causing significant wear and tear, and shortening the service life. Furthermore, existing hinges typically utilize four support rods, resulting in a complex load-bearing structure and limited smooth movement. Therefore, the existing technology remains to be improved and developed. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a hinge and door and window assembly, aiming to solve the problems of the existing hinges such as long sliding distance, large wear and tear, and short service life.

[0004] The technical solution adopted by the present invention to solve the technical problem is as follows: providing a hinge, comprising a horizontal bracket for mounting doors and windows, a connecting rod assembly, and a first slide seat and a second slide seat that can slide relative to each other, wherein the connecting rod assembly is respectively connected to the horizontal bracket, the first slide seat and the second slide seat in a transmission manner;

[0005] The hinge further comprises a gear, and the first slide and the second slide are both provided with a rack meshing with the gear, so that the first slide and the second slide slide synchronously slide in opposite directions.

[0006] Furthermore, the rack of the first slide seat and the rack of the second slide seat are engaged in parallel on both sides of the gear.

[0007] Furthermore, the connecting rod assembly includes a first support rod, a second support rod and a third support rod; the first support rod is respectively connected to the first slide and the horizontal bracket, the third support rod is respectively rotatably connected to the second slide and the horizontal bracket; the second support rod is rotatably connected to the first slide and the third support rod;

[0008] When the first slide and the second slide move closer to or farther from each other, the first support rod and the third support rod rotate in the same direction, the second support rod and the horizontal bracket rotate in the same direction and opposite to the third support rod.

[0009] Furthermore, the first support rod is rotatably mounted on the first slide via a first axis, the second support rod is rotatably mounted on the first slide via a second axis; the third support rod is rotatably mounted on the second slide via a third axis, and the second axis is located between the first axis and the third axis.

[0010] Furthermore, the third support rod is rotatably connected to the second support rod via a fourth axis, and is rotatably connected to the horizontal bracket via a fifth axis, and the fourth axis is located between the third axis and the fifth axis.

[0011] Furthermore, the horizontal bracket is rotatably connected to the first support rod via a sixth axis, and the sixth axis is located between the first axis and the fifth axis.

[0012] Furthermore, the hinge also includes hinges for facilitating the installation of doors and windows, and the hinges are installed on the sixth axis.

[0013] Furthermore, the horizontal bracket is located above the first support rod and the third support rod, and the first support rod and the third support rod support the horizontal bracket.

[0014] Furthermore, the third support rod is located above the second support rod, and the second support rod supports the third support rod; when the first slide and the second slide are close to each other, the horizontal bracket moves away from the first slide, thereby opening the doors and windows; when the first slide and the second slide are away from each other, the horizontal bracket moves close to the first slide, causing the second support rod, the third support rod and the horizontal bracket to overlap, thereby closing the doors and windows.

[0015] Furthermore, the hinge also includes a guide rail for installation on the door and window frame, the first slide seat and the second slide seat are both slidably arranged on the guide rail, and the gear is rotatably arranged on the guide rail.

[0016] Furthermore, the hinge further comprises a motor, which is transmission-connected to the gear and can drive the gear to rotate, thereby driving the first slide and the second slide to slide synchronously in opposite directions.

[0017] The present invention also provides a door and window assembly, comprising a door and window and a door and window frame, and also comprising the above-mentioned hinges installed on the door and window and the door and window frame.

[0018] Compared with the existing hinge structure in which one side is fixed and the other side slides, the present invention provides a hinge and door and window assembly, which enables the first slide and the second slide to slide synchronously in opposite directions by setting gears. This structure in which two sides slide can shorten the sliding distance of the components and greatly improve their service life. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] Now, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0027] The present invention provides a door and window assembly, comprising a door and window 100 and a door and window frame 200, and further comprising a hinge 300 mounted on the door and window 100 and the door and window frame 200. Figure 1 The door and window 100 is opened by the hinge 300; Figure 2 This is a diagram of the door and window 100 in a closed state, where the door and window 100 is closed via the hinge 300 .

[0028] like Figure 3 As shown, the hinge 300 includes a horizontal bracket 40 for mounting the door or window 100, a connecting rod assembly, and a first slide 50 and a second slide 60 that can slide relative to each other. The connecting rod assembly is in driving connection with the horizontal bracket 40, the first slide 50, and the second slide 60, respectively. The hinge 300 also includes a gear 90. The first and second slides 50 and 60 are each equipped with a rack 91 that meshes with the gear 90, enabling synchronous, opposite-direction sliding of the first and second slides 50 and 60. By providing the gear 90 to enable synchronous, opposite-direction sliding of the first and second slides 50 and 60, this dual-sliding structure can shorten the sliding distance of the components and significantly improve their service life.

[0029] In this embodiment, the rack of the first slide 50 and the rack of the second slide 60 are engaged in parallel on both sides of the gear 90, making the movement of the entire mechanism more compact and smooth.

[0030] like Figure 4As shown, the connecting rod assembly includes a first support rod 10, a second support rod 20, and a third support rod 30. The first support rod 10 is connected to the first slide 50 and the horizontal bracket 40, respectively, and the third support rod 30 is rotatably connected to the second slide 60 and the horizontal bracket 40, respectively. The second support rod 20 is rotatably connected to the first slide 50 and the third support rod 30. When the first slide 50 and the second slide 60 move closer to or further away from each other, the first support rod 10 and the third support rod 30 rotate in the same direction, and the second support rod 20 rotates in the same direction as the horizontal bracket 40 and in the opposite direction to the third support rod 30. By using three support rods, the doors and windows can be opened and closed with fewer components, a simpler structure, and smoother movement.

[0031] In this embodiment, the hinge 300 further includes a guide rail 80 for mounting on the door / window frame 200. The first slide 50 and the second slide 60 are both slidably mounted on the guide rail 80, and the gear 90 is rotatably mounted on the guide rail 80. Of course, the guide rail 80 may not be separately provided, but may be directly machined into the door / window frame 200, or the guide rail may be integrally formed with the door / window frame, thus still enabling the first slide 50 and the second slide 60 to slide.

[0032] Specifically, the guide rail 80 is provided with a special-shaped slot, and both the first slide 50 and the second slide 60 are provided with sliders that cooperate with the slot. The sliders slide along the special-shaped slot. The first slide 50 and the second slide 60 can be installed by sliding them into the special-shaped slot from one end of the guide rail 80. This installation method is stable, compact, and not prone to shaking.

[0033] The door and window 100 is installed on the horizontal bracket 40 and rotates with the horizontal bracket 40. Specifically, a plurality of mounting holes 41 are provided on the horizontal bracket 40 to facilitate fixing the door and window 100 with screws.

[0034] In order to install the door and window 100 more stably, the hinge 300 further includes a hinge 70. The hinge 70 is arranged on the horizontal bracket 40, and the side of the door and window 100 is fixed to the hinge 70 by screws.

[0035] refer to Figure 4The first support rod 10 is rotatably mounted on the first slide 50 via the first axis 1, and the second support rod 20 is rotatably mounted on the first slide 50 via the second axis 2. The third support rod 30 is rotatably mounted on the second slide 60 via the third axis 3, with the second axis 2 being located between the first axis 1 and the third axis 3. Furthermore, the third support rod 30 is rotatably connected to the second support rod 20 via the fourth axis 4, and is rotatably connected to the horizontal bracket 40 via the fifth axis 5, with the fourth axis 4 being located between the third axis 3 and the fifth axis 5. Thus, the lines connecting the second axis 2, the third axis 3, and the fourth axis 4 on the same plane form a triangle. When the first slide 50 and the second slide 60 slide in opposite directions, the second support rod 20 and the third support rod 30 rotate in opposite directions. For example, when the first slide 50 and the second slide 60 approach each other, the second support rod 20 rotates counterclockwise, while the third support rod 30 rotates clockwise.

[0036] In addition, the horizontal bracket 40 is rotatably connected to the first support rod 10 via the sixth axis 6, which is located between the first axis 1 and the fifth axis 5. Thus, the lines connecting the first axis 1, the second axis 2, the fourth axis 4, the fifth axis 5, and the sixth axis 6 on the same plane form a pentagon, so that the first support rod 10 and the third support rod 30 rotate in the same direction, and the second support rod 20 and the horizontal bracket 40 rotate in the same direction.

[0037] Specifically, the hinge 70 is mounted on the sixth axis 6, facilitating installation of the door and window 100. The side lengths of the triangle and pentagon are adjusted as needed to ensure smooth opening and closing of the door and window 100. In this embodiment, the second support rod 20 is longer than the first support rod 10, and the third support rod 30 is longer than the second support rod 20.

[0038] In this embodiment, the horizontal bracket 40 is located above the first support rod 10 and the third support rod 30. The first support rod 10 and the third support rod 30 support the horizontal bracket 40 via the sixth axis 6 and the fifth axis 5. When the door and window 100 are installed on the horizontal bracket 40, the first support rod 10 and the third support rod 30 can stably support the door and window 100.

[0039] To further improve the stability of the door and window 100, the third support rod 30 is located above the second support rod 20, and the second support rod 20 supports the third support rod 30 through the fourth shaft 4. In other words, the first support rod 10, the second support rod 20 and the third support rod 30 jointly support the door and window 100. This structure is stable and greatly improves the supporting strength.

[0040] In addition, the horizontal bracket 40 is located above the first support rod 10 and the third support rod 30, and the third support rod 30 is located above the second support rod 20. This structure is beneficial for the first support rod 10, the second support rod 20, the third support rod 30 and the horizontal bracket 40 to overlap and store when the door and window 100 is closed, thereby avoiding interference.

[0041] In another embodiment, the hinge 300 further includes a motor (not shown) that is in transmission connection with the gear 90 and can drive the gear 90 to rotate, thereby causing the first slide 50 and the second slide 60 to slide synchronously in opposite directions. By using the motor, the door and window 100 can be automatically opened or closed, which is more convenient and intelligent to use.

[0042] like Figure 5 , is a schematic diagram of the structure of the hinge 300 when the door and window 100 is in a half-open state. When the first slide 50 and the second slide 60 approach each other, the horizontal bracket 40 rotates counterclockwise and moves away from the first slide 50, thereby opening the door and window 100. Figure 1 and 3 When the door and window 100 is opened to the maximum position, the angle between the horizontal bracket 40 and the guide rail 80 is almost 90°.

[0043] refer to Figure 2 and 6 When the first slide 50 and the second slide 60 move away from each other, the horizontal bracket 40 approaches the first slide 50, and the horizontal bracket 40 rotates clockwise, causing the second support rod 20, the third support rod 30 and the horizontal bracket 40 to overlap, thereby closing the door and window 100.

[0044] It should be understood that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Those skilled in the art may modify the technical solutions described in the above embodiments, or make equivalent replacements for some of the technical features therein; and all these modifications and replacements should fall within the scope of protection of the claims attached to the present invention.
