Inward tilt-and-turn window with child safety lock

Abstract

This inward-tilting window with a child safety lock belongs to the field of inward-tilting window technology. It aims to solve the problem of children easily opening inward-tilting windows without supervision, potentially leading to objects being thrown from heights. The inward-tilting window features a rectangular frame containing two pieces of high-transparency glass with protective films. A rectangular groove runs along the upper edge of the frame, containing a locking bolt. The groove opening has a rotatable sealing plate. The top of the locking bolt can be inserted into a circular slot at the top of the inner wall of the window frame, and its bottom cap has an internal hexagonal groove. The sealing plate is rotatably connected to the rectangular frame via a protrusion. An L-shaped abutment is located at the lower right corner of the rectangular groove. When the locking bolt is inserted into the slot and rotated to lock, and the sealing plate covers the groove opening, it is difficult for children to operate the locking bolt, reducing the likelihood of opening the inward-tilting window. The protective film reduces ultraviolet radiation, protecting people and items inside the window.

Description

Technical Field

[0001] This utility model relates to the field of tilt-and-turn windows, and more particularly to tilt-and-turn windows with child safety locks. Background Technology

[0002] In daily life, windows, as an important part of the connection between indoors and outdoors, pose certain safety hazards. To prevent children from climbing on the windowsill and falling, some users have replaced traditional casement windows with tilt-and-turn windows.

[0003] Inward tilt-and-turn windows limit the opening range by tilting the window sash inward, but in actual use, it has been found that children can still change the opening state by pushing or pulling the window sash handle or directly prying the edge of the window sash. Especially when unsupervised, this may lead to dangerous behaviors such as throwing objects from heights.

[0004] To address the aforementioned issues, this utility model document proposes an inward-tilting window with a child safety lock. Utility Model Content

[0005] This utility model provides an inward tilt-and-turn window with a child safety lock, which solves the problem that in the prior art, the opening range of the inward tilt-and-turn window is limited by the inward tilting opening method of the window sash. However, in actual use, it has been found that children can still change the opening state by pushing and pulling the window sash handle or directly prying the edge of the window sash. Especially when there is no supervision, this may lead to dangerous behaviors such as throwing objects from a height.

[0006] This utility model provides the following technical solution: Inward-tilting windows with child safety locks include: The inward tilt-and-turn window body has two pieces of high-transparency glass fixedly installed inside the rectangular frame of the inward tilt-and-turn window body. There is a hollow cavity between the two pieces of high-transparency glass. A protective film for reducing ultraviolet radiation is evenly applied to the outer wall of the high-transparency glass. The rectangular frame is installed in the window frame through matching hardware on the side. A matching handle is installed on the rectangular frame. The upper edge of the rectangular frame is provided with a rectangular groove, a limit bolt is provided in the rectangular groove, and a rotatable sealing piece is provided at the opening of the rectangular groove.

[0007] In one possible design, the protective film is a transparent polymethyl methacrylate film containing benzotriazole UV absorbers.

[0008] In one possible design, a threaded hole adapted to the outer bolt of the limiting bolt is provided at the center of the top of the inner wall of the rectangular groove, and the top of the limiting bolt passes through the threaded hole and is inserted into the corresponding circular slot on the top of the inner wall of the window frame.

[0009] In one possible design, the bottom of the limiting screw cap is provided with an internal hexagonal groove for use with an internal hexagonal wrench.

[0010] In one possible design, a tab extends from the upper left corner of the sealing piece, and the tab is rotatably connected to a mounting groove on the outer wall of the rectangular frame via a pin on the inner wall.

[0011] In one possible design, an L-shaped abutment for supporting the lower right corner of the sealing piece is fixedly provided at the lower right corner of the rectangular groove.

[0012] It should be understood that the above general description and the following detailed description are merely exemplary and do not limit the present invention.

[0013] The working principle and usage process of this technical solution are as follows: In use, the inward tilt-and-turn window can be opened and closed normally by rotating the matching handle installed on the rectangular frame to meet daily ventilation needs. When it is necessary to prevent children from opening the inward tilt-and-turn window, rotate the sealing piece around the pin to the upper left to open the rectangular groove. Then manually rotate the limit bolt. If it is difficult, an Allen wrench can be used to assist in the rotation by inserting it into the Allen groove, so that the top of the limit bolt is inserted into the corresponding circular slot at the top of the inner wall of the window frame. Rotating the limit bolt will make the connection between it and the window frame tighter and completely prevent the inward tilt-and-turn window from opening. Since the rectangular groove is located on the upper edge of the rectangular frame, young children cannot reach the limit bolt. Then rotate the sealing piece around the pin to the upper right until the L-shaped abutment supports the lower right corner of the sealing piece, so that it covers the groove of the rectangular groove again and prevents the limit bolt from being exposed. When it is necessary to open the inward tilt-and-turn window normally, rotate the limit bolt in the opposite direction to release the restriction on the rectangular frame.

[0014] This utility model has the following beneficial effects: This invention, by setting a limiting bolt and a rotatable sealing plate, makes it difficult for children to operate the limiting bolt at will to change the opening state of the window when the limiting bolt is inserted into the circular slot at the top of the inner wall of the window frame and rotated to lock, and the sealing plate covers the rectangular slot. This greatly reduces the possibility of children opening the inward tilt window without supervision and effectively avoids dangerous situations such as children throwing objects from heights.

[0015] In this invention, the bottom cap of the limiting bolt has an internal hexagonal groove, requiring a specific internal hexagonal wrench for easy operation, which further increases the difficulty for children to open.

[0016] The protective film uniformly applied to the outer wall of the high-transparency glass in this invention is a polymethyl methacrylate transparent film with added benzotriazole ultraviolet absorbers. It can effectively reduce ultraviolet radiation, protect indoor people and objects from ultraviolet damage, and further enhance the functionality and practicality of the window.

[0019] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0020] In the description of this utility model, it should be understood that the terms "opening", "upper", "middle", "length", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0021] To keep the following description of the embodiments of this utility model clear and concise, detailed descriptions of known functions and known components are omitted.

[0022] In one embodiment: Please refer to Figure 1-4 Inward tilt-and-turn windows, including: The inward tilt-and-turn window body 1 consists of a rectangular frame 2 forming the main support structure. The rectangular frame 2 is made of thermally broken aluminum alloy profile and is connected to the window frame through matching hardware (including hinges). Two pieces of high-transparency glass 3 are embedded in the rectangular frame 2, with a 12mm gap between the two pieces of glass to form a hollow cavity. The hollow cavity can be filled with argon gas to improve thermal insulation performance. A matching handle 4 is installed on the rectangular frame 2. The handle 4 is fixed to the handle seat of the rectangular frame 2 with M4 countersunk screws. The handle seat is connected to the window sash drive rod. Rotating the handle 4 can drive the drive rod to move, realizing the adjustment of the opening angle of the inward tilt-and-turn window (maximum opening angle 15°) to meet daily ventilation needs.

[0023] A rectangular groove 5 is provided on the upper edge of the rectangular frame 2. A threaded hole 7, which is adapted to the outer bolt of the limit bolt 8, is machined at the center of the top of the inner wall of the rectangular groove 5. The thread specification is M6×1.0 and it penetrates vertically through the thickness direction of the rectangular frame 2. The top of the limit bolt 8, made of 304 stainless steel, passes through the threaded hole 7 and is inserted into the corresponding circular slot on the top of the inner wall of the window frame. Rotating the limit bolt 8 can make its connection with the window frame tighter, thereby completely preventing the inward tilt window from opening. The bottom of the cap of the limit bolt 8 is provided with an internal hexagonal groove 9. When it is difficult to rotate the limit bolt 8 manually, an internal hexagonal wrench can be used to insert into the internal hexagonal groove 9 to assist in rotation. However, the use of an internal hexagonal wrench makes the operation easier and increases the difficulty for children to open.

[0024] A rotatable sealing piece 10 is provided at the opening of the rectangular groove 5. A protrusion 11 extends from the upper left corner of the sealing piece 10. The protrusion 11 is rotatably connected to the mounting groove on the outer wall of the rectangular frame 2 through a cylindrical pin on the inner wall, so that the sealing piece 10 can rotate around the pin. An L-shaped abutment 12 is fixedly provided at the lower right corner of the rectangular groove 5 and is fixed to the surface of the rectangular frame 2 by adhesive. When the sealing piece 10 rotates around the pin to a certain position, the L-shaped abutment 12 can support the lower right corner of the sealing piece 10, so that the sealing piece 10 covers the opening of the rectangular groove 5, forming a stable closed state and preventing the limit bolt 8 from being exposed.

[0025] When it is necessary to prevent children from opening the tilt-and-turn window, first rotate the sealing piece 10 around the pin to the upper left to open the rectangular groove 5. Then manually rotate the limiting bolt 8. If it feels difficult, insert the Allen wrench into the Allen groove 9 to assist in the rotation, so that the top of the limiting bolt 8 is inserted into the corresponding circular slot at the top of the inner wall of the window frame. By rotating the limiting bolt 8, it is tightly connected to the window frame, completely preventing the tilt-and-turn window from opening. Since the rectangular groove 5 is located on the upper edge of the rectangular frame 2, young children cannot reach the limiting bolt 8. Then rotate the sealing piece 10 around the pin to the upper right until the L-shaped abutment 12 supports the lower right corner of the sealing piece 10, so that the sealing piece 10 covers the groove of the rectangular groove 5 again, preventing the limiting bolt 8 from being exposed. When it is necessary to open the tilt-and-turn window normally, rotate the limiting bolt 8 in the opposite direction to release the restriction on the rectangular frame 2. Then the tilt-and-turn window can be opened by rotating the handle 4.

[0026] This application can be used for inward-tilting windows, or in other fields applicable to this application.

[0027] In another embodiment: Inward tilt-and-turn windows with child safety locks are used in the field of inward tilt-and-turn windows; Please refer to Figure 4 The outer wall of the high-transparency glass 3 is uniformly covered with a protective film 6 by optical-grade pressure-sensitive adhesive. The protective film 6 is a transparent polymethyl methacrylate film, in which 2.5% by mass of benzotriazole ultraviolet absorber is uniformly incorporated. It can effectively absorb ultraviolet rays with a wavelength of 300-400nm, thereby effectively reducing ultraviolet radiation and protecting indoor personnel and objects from ultraviolet damage. At the same time, it hardly absorbs visible light above 400nm and can convert ultraviolet energy into harmless heat energy, thereby preventing material aging and discoloration.

[0028] The accompanying drawings in this application are for illustrative purposes only. The dimensions and shapes of the components shown are not actual limitations but are merely schematic representations. In actual implementation, the components can be reasonably configured and adjusted according to specific needs and actual conditions.

[0029] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. In the absence of conflict, the embodiments and features in the embodiments of this utility model can be combined with each other. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
