Description

Technical Field

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

[0002] Casement windows include outward-opening windows and inward-opening windows. Each has its advantages and disadvantages. Inward-opening windows are very convenient for cleaning, glass replacement and other maintenance because the window sash rotates inward when opened. Inward-opening tilt-and-turn windows are a modern type of window that adds a tilt-and-turn function to the inward-opening function. It is a type of window that can achieve two opening methods by operating the handle of the window sash. In the tilt-and-turn state, the upper part of the window sash tilts inward while the lower part remains stationary, opening a gap to achieve micro-ventilation of the room.

[0003] The hinges used in this type of inward-opening and tilt-and-turn window differ from those of ordinary casement windows, especially the upper hinge. In general, the upper and lower hinges of a casement window are the same, including a window sash connecting rod fixedly installed on the window sash. However, the upper hinge of an inward-opening and tilt-and-turn window also needs to achieve the tilt-and-turn function, as illustrated in the utility model patent CN218347171U, entitled "A Type of Inward-Opening and Tilting Upper and Lower Hinge." Therefore, the window sash connecting rod of this hinge also includes an inward-tilting connecting rod, which is installed and connected to the window sash. The inward-tilting connecting rod is movably connected to... The window sash linkage has a positioning groove, and the tilt-and-turn linkage has a locking pin. The locking pin is slid into the positioning groove by the handle, and the positioning groove and locking pin restrict the linkage from rotating along the window sash linkage. However, the window sash linkage and the tilt-and-turn linkage are positioned only by the locking pin and the positioning groove. Furthermore, due to the special nature of inward-opening and tilt-and-turn windows, the hinges of each part of the hinge cannot be set too tight. That is, the connection between the window sash linkage and the window frame mounting plate is relatively loose. As a result, the wind pressure resistance of the current inward-opening and tilt-and-turn windows is insufficient, and the window sash is very easy to shake in strong winds. Utility Model Content

[0004] The present invention provides an upper hinge for an inward-opening and tilt-and-turn window to solve the aforementioned problems.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an upper hinge for an inward-opening and tilt-and-turn window, comprising a window frame mounting plate, a window sash connecting rod, and an inward-tilting connecting rod. The window sash connecting rod has a positioning groove in the middle, and one end is hinged to the window frame mounting plate via a connecting rod, while the other end is movably connected to the inward-tilting connecting rod. The inward-tilting connecting rod is slidably provided with a locking post, which is slidably disengaged from the positioning groove. The window frame mounting plate is provided with a limiting plate for tightly abutting against the locking post, and the limiting plate is located on the outdoor side of the locking post.

[0006] Furthermore, the limiting plate is inclinedly disposed on the sliding path of the locking pin.

[0007] Furthermore, when the upper hinge is folded, one end of the limiting plate is positioned on one side of the positioning groove and gradually tilts towards the centerline in the width direction of the positioning groove.

[0008] Furthermore, the window sash connecting rod is provided with a connecting arm hinged to the inward connecting rod.

[0009] Furthermore, the width of the positioning groove corresponds to the diameter of the locking pin.

[0010] Compared with the prior art, the beneficial effects of this utility model are: by setting a limiting plate on the window frame mounting plate, when the window sash is closed, the locking pin of the inward tilting linkage slides into the positioning groove and abuts against the limiting plate. The limiting plate of the window frame mounting plate prevents the locking pin from moving along the thickness direction of the window sash, thereby preventing the window sash connected to the inward tilting linkage from shaking and improving wind pressure resistance.

[0017] 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.

[0018] As shown in the attached figure, the present invention discloses an upper hinge for an inward-opening and tilt-and-turn window, comprising a window frame mounting plate 1, a window sash connecting rod 2, and an inward-tilting connecting rod 3. The window sash connecting rod 2 has a positioning groove 20 in the middle, one end of which is hinged to the window frame mounting plate 1 via a connecting rod, and the other end is movably connected to the inward-tilting connecting rod 3. The inward-tilting connecting rod 3 is slidably provided with a locking pin 31, which is slidably disengaged from the positioning groove 20. The inward-tilting connecting rod 3 specifically includes a fixed part and a sliding part, the sliding part being connected to a handle. The window frame mounting plate 1 is provided with a limiting plate 11 for pressing against the locking pin 31, and the limiting plate 11 is located on the outdoor side of the locking pin 31.

[0019] This utility model discloses an upper hinge for an inward-opening and tilt-and-turn window. By using a limiting plate 11 set on the window frame mounting plate 1, when the window sash is closed, the locking pin 31 of the tilt-and-turn linkage 3 slides into the positioning groove 20 and abuts against the limiting plate 11. The limiting plate 11 of the window frame mounting plate 1 prevents the locking pin 31 from moving along the thickness direction of the window sash, thereby preventing the window sash connected to the tilt-and-turn linkage 3 from shaking and improving wind pressure resistance.

[0020] Specifically, the limiting plate 11 is inclinedly disposed on the sliding path of the locking pin 31. When the upper hinge is folded, one end of the limiting plate 11 is disposed on one side of the positioning groove 20 and gradually tilts towards the center line of the width direction of the positioning groove 20. The locking pin 31 slides into the positioning groove 20 from one end and can slide linearly within the positioning groove 20. The limiting plate 11 is inclinedly disposed at the other end of the positioning groove 20. As the locking pin 31 gets closer to the other end of the positioning groove 20, the contact between the locking pin 31 and the limiting plate 11 becomes tighter.

[0021] Specifically, the window sash connecting rod 2 is provided with a connecting arm 203 that is hinged to the inward tilting connecting rod 3. The connecting arm 203 is used to increase the connection strength between the window sash connecting rod 2 and the inward tilting connecting rod 3, thereby improving the stability of the window sash.

[0022] Specifically, the width of the positioning groove 20 corresponds to the diameter of the locking pin 31, ensuring linear sliding between the locking pin 31 and the positioning groove 20. A limiting block for abutting the window frame mounting plate 1 can also be added to the window sash connecting rod 2. This ensures that the window frame mounting plate 1 and the window sash connecting rod 2 remain parallel during folding and retraction. After the window frame mounting plate 1 and the window sash connecting rod 2 are folded and aligned, the limiting block on the window sash connecting rod 2 abuts against the outdoor side of the window frame mounting plate 1.

[0023] Based on the existing upper hinge structure of inward-opening and tilt-and-turn windows, the upper side of the window sash is fixedly connected to the tilt-and-turn linkage 3. The tilt-and-turn linkage 3 has a fixed part and a sliding part. Specifically, the window sash is connected to the fixed part of the tilt-and-turn linkage 3. The locking pin 31 is set on the sliding part of the tilt-and-turn linkage 3. One end of the window sash linkage 2 is also movably connected to the sliding part of the tilt-and-turn linkage 3. When the window sash is in the tilt-and-turn state, i.e., when the window sash is tilted inward, the window sash is in the tilt-and-turn state. Figure 1As shown, at this time, the locking pin 31 is disengaged from the positioning groove 20. When the window sash is in the inward opening state, the locking pin 31 is in the positioning groove 20, and one end of the window sash connecting rod 2 is movably connected to the inward tilting connecting rod 3. The cooperation between the locking pin 31 and the positioning groove 20 restricts the swing of the inward tilting connecting rod 3, so that the inward tilting connecting rod 3 and the window sash connecting rod 2 remain aligned, i.e. Figure 2 As shown, when the window sash is locked, the hinges are folded and retracted as a whole, that is, the inward tilting link 3, the window sash link 2 and the window frame mounting plate 1 are all aligned. The window frame mounting plate 1 is blocked on the outside side of the locking post 31 by the limiting plate 11 and is kept in a tight abutment with the locking post 31. Since the window frame mounting plate 1 is fixedly connected to the window frame, the stable window frame mounting plate 1 prevents the inward tilting link 3 from moving, thereby improving the overall wind pressure resistance performance.

[0024] 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.
