Inwardly opening inwardly tilting window lower hinge

Abstract

This utility model relates to the field of hinge technology, and in particular to a lower hinge for an inward-opening and tilt-and-turn window. It includes a window frame mounting plate and a window sash mounting plate fixedly installed at the bottom of the window sash. The window frame mounting plate is hinged to the window sash mounting plate via a connecting rod. A vertical post is vertically installed at one end of the window sash mounting plate, and a kit is slidably connected to one side of the window sash by inserting it into the post. The kit is equipped with connecting screws for fixing it to the window sash. The lower hinge is fixedly connected to the bottom of the window sash via the window sash mounting plate. The post at one end of the window sash mounting plate and the kit installed on one side of the window sash allow the lower hinge to be fixedly connected to one side of the window sash via the post. This achieves a double-sided connection between the lower hinge and the window sash, increasing the connection surface and thus improving the connection strength and reducing safety hazards.

Description

Technical Field

[0001] This utility model relates to the technical field of hinges, and in particular to a hinge for an inward-opening and inward-tilting window. Background Technology

[0002] Inward-opening and tilt-and-turn windows, combining both inward opening and tilting mechanisms, provide a micro-ventilation channel for the interior, achieving good ventilation while also ensuring safety and rain protection. Therefore, they are widely used in modern architecture. The lower hinge, as one of the main components of an inward-opening and tilt-and-turn window, directly affects the overall performance, safety, and lifespan of the window. The lower hinge has the same main structure as that of a regular casement window, including a frame mounting plate, a sash mounting plate, and a connecting rod. The sash mounting plate is hinged to the frame mounting plate via the connecting rod. However, due to the need to accommodate the inward tilting of the sash, the hinge between the sash mounting plate and the frame mounting plate must not be too tight, requiring a certain amount of slack. Referring to the patent publication (announcement) number: CN113338736B, entitled "A Casement Window Hinge with Adjustable Opening Angle," it can be seen that existing sash mounting plates are flat and only connected to the lower side of the sash with screws. This single-sided connection structure has insufficient connection strength and poses a safety hazard. Utility Model Content

[0003] The present invention provides a lower hinge for an inward-opening and tilt-and-turn window to solve the aforementioned problems.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a hinge for an inward-opening and tilt-and-turn window, comprising a window frame mounting plate and a window sash mounting plate fixedly disposed at the bottom of the window sash. The window frame mounting plate is hinged to the window sash mounting plate via a connecting rod. A column is vertically disposed at one end of the window sash mounting plate. A kit is slidably connected to one side of the window sash and inserted into the outside of the column. The kit is provided with connecting screws for fixing the kit to the window sash.

[0005] Furthermore, the kit is provided with a circular hole corresponding to the diameter of the column, and the circular hole extends through both ends of the kit in the length direction.

[0006] Furthermore, the kit is provided with screw holes that extend through both ends in the thickness direction.

[0007] Furthermore, one side of the kit is provided with a sliding part that is slidably connected to the hardware groove of the window sash.

[0008] Furthermore, one end of the window frame mounting plate is vertically provided with a vertical plate for fixing and connecting to one side of the window frame.

[0009] Furthermore, one end of the window sash mounting plate is hinged to one end of the connecting rod via a column.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: the window sash mounting plate is fixedly connected to the bottom of the window sash, and a column is set at one end of the window sash mounting plate. A kit is installed on one side of the window sash, and the lower hinge is inserted into the kit using the column, thereby realizing the fixed connection between the lower hinge and one side of the window sash. This achieves a double-sided connection between the lower hinge and the window sash, increases the connection surface between the lower hinge and the window sash, and thus improves the connection strength between the lower hinge and the window sash, reducing safety hazards.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] As shown in the attached figure, the present invention provides a hinge for an inward-opening and tilt-and-turn window, comprising a window frame mounting plate 1 and a window sash mounting plate 2 fixedly disposed at the bottom of the window sash. The window frame mounting plate 1 is hinged to the window sash mounting plate 2 via a connecting rod 3. The window sash mounting plate 2 is fixedly connected to the bottom surface of the window sash by screws. A column 41 is vertically disposed at one end of the window sash mounting plate 2. A kit 4 is slidably connected to one side of the window sash by inserting it into the column 41. The kit 4 is provided with connecting screws 411 for fixing the kit 4 to the window sash. The kit 4 slides in a hardware groove on one side of the window sash.

[0018] This utility model discloses a lower hinge for an inward-opening and tilt-and-turn window. It is fixedly connected to the bottom of the window sash via a window sash mounting plate 2. A column 41 is provided at one end of the window sash mounting plate 2, and a kit 4 is installed on one side of the window sash. The lower hinge is inserted into the kit 4 via the column 41, thereby achieving a fixed connection between the lower hinge and one side of the window sash. This realizes a double-sided connection between the lower hinge and the window sash, increases the connection surface between the lower hinge and the window sash, and thus improves the connection strength between the lower hinge and the window sash, reducing safety hazards.

[0019] Specifically, the kit 4 is provided with a circular hole 400 corresponding to the diameter of the column 41, and the circular hole 400 passes through both ends of the kit 4 in the length direction. The kit 4 is provided with a screw hole 401, and the screw hole 401 passes through both ends of the thickness direction. The screw hole 401 and the circular hole 400 are not connected to each other. The circular hole 400 fits tightly with the column 41, and the kit 4 can rotate on the column 41.

[0020] Specifically, the kit 4 has a sliding part 404 on one side that is slidably connected to the hardware groove of the window sash. The sliding part 404 is located in the hardware groove and slides linearly along the hardware groove.

[0021] Specifically, one end of the window frame mounting plate 1 is vertically provided with a vertical plate 101 for fixing to one side of the window frame. The vertical plate 101 is also provided with screw holes 401, through which screws are inserted and fixed to the window frame.

[0022] Specifically, one end of the window sash mounting plate 2 is hinged to one end of the connecting rod 3 via a column 41, and one end of the connecting rod 3 is hinged to one end of the window sash mounting plate 2. The column 41 is used instead of rivets to achieve the hinge, which facilitates production.

[0023] The above embodiments are preferred embodiments of this utility model. All structures similar to this utility model and equivalent changes thereof should fall within the protection scope of this utility model.
