Description

Technical Field

[0001] This utility model relates to the field of window technology, and in particular to an anti-collision and anti-fall-off corner guard for an inward-opening window sash. Background Technology

[0002] In related technologies, most windows have screens on the outside and sashes on the inside, which means that most windows open inwards. Window sashes are usually cuboid in structure, with multiple sharp corners at the four corners; once the user opens the window inwards, these sharp corners become exposed and can easily scratch a child's head and an adult's waist, arms, etc.

[0003] Based on the aforementioned shortcomings, many window sash corner protectors have emerged on the market to cover these sharp corners. These corner protectors are usually bonded to the surface of the window sash profile using self-adhesive (such as double-sided tape). However, using adhesive to fix the corner protectors can lead to them falling off after prolonged use, causing safety hazards to reappear and resulting in a poor user experience. Secondly, protruding corner protectors can disrupt the overall flatness of the window sash, appearing particularly abrupt and lacking in aesthetic appeal. Window sashes need to fit tightly against the window frame to achieve a seal. If the corner protectors protrude, they may interfere with the window frame when the window is closed, preventing the window from closing completely and severely affecting the window's sealing performance, leading to a decrease in sound insulation and heat preservation.

[0004] Therefore, a new technical solution needs to be researched to address the above problems. Utility Model Content

[0005] In view of this, the present invention addresses the deficiencies of the existing technology, and its main purpose is to provide an anti-collision and anti-fall-off corner protector for an inward-opening window sash, effectively solving the technical defects in the existing technology where the corner protectors are installed by adhesive, resulting in easy fall-off, poor flatness, and affecting the sealing performance of the window.

[0006] This utility model provides an anti-collision and anti-fall-off corner guard for an inward-opening window sash, including a window sash and a corner guard disposed on the window sash. The window sash includes at least a first profile extending in a first direction and a second profile extending in a second direction. One end of the first profile and one end of the second profile are connected together. The first profile is provided with a first insertion interface, the second profile is provided with a second insertion interface, and the connection between the first profile and the second profile is provided with a cutout that can expose the first insertion interface and the second insertion interface. The corner protector includes an insert, a first insertion part integrally formed on one surface of the insert, and a second insertion part integrally formed on the other surface of the insert. When the first insertion part is inserted into the first insertion interface and the second insertion part is inserted into the second insertion interface, the insert can cover the cut and make the outer surface of the insert smoothly transition to the outer surfaces of the first profile and the second profile, respectively.

[0007] The beneficial effects of the anti-collision and anti-fall-off corner protector for inward-opening window sash provided by this utility model are as follows: Compared with the prior art, firstly, by setting a first insertion interface on the first profile and a second insertion interface on the second profile, and setting a cut between the first profile and the second profile that exposes the first insertion interface and the second insertion interface; during the assembly of the corner protector, the first insertion part is inserted into the first insertion interface, and the second insertion part is inserted into the second insertion interface, so that the outer insert covers the cut and completes the connection and fixation between the corner protector and the first profile and the second profile. This fixing method realizes mechanical connection, completely abandons the fixing method that relies on adhesives, fundamentally solves the technical defect of corner protectors being easy to fall off in traditional technology, thereby improving the connection strength and service life of the corner protector, enabling the window sash to be continuously protected by the corner protector, eliminating safety hazards and improving the user experience; Secondly, since the first insertion part is inserted into the first insertion interface and the second insertion part is inserted into the second insertion interface, the outer insert can cover the cut and make the outer surface of the outer insert smoothly transition to the outer surfaces of the first profile and the second profile, respectively. This solves the technical defect of the corner protector protruding from the profile surface in the traditional technology. It can not only improve the overall flatness of the window sash and make it more concise and beautiful, but also make the window sash fit tightly with the window frame when the window sash is closed without interference, thereby improving the sealing performance of the window and ensuring that the sound insulation and heat preservation effects are not affected by the setting of the corner protector.

In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0025] Please refer to the following: Figures 1 to 7 The anti-collision and anti-fall-off corner guard 20 of the inward-opening window sash 10 provided in this application embodiment will now be described. The anti-collision and anti-fall-off corner guard 20 of the inward-opening window sash 10 includes the window sash 10 and the corner guard 20.

[0026] The corner protector 20 is assembled to the window sash 10 by a plug-in connection. The window sash 10 includes at least a first profile 11 extending in a first direction and a second profile 12 extending in a second direction. One end of the first profile 11 and one end of the second profile 12 are connected together. The first profile 11 is provided with a first plug-in interface 111, and the second profile 12 is provided with a second plug-in interface 121. The connection between the first profile 11 and the second profile 12 is provided with a cutout 13 that exposes the first plug-in interface 111 and the second plug-in interface 121. The corner protector 20 includes an insert 21, a first plug-in portion 22 integrally formed on one surface of the insert 21, and a second plug-in portion 23 integrally formed on the other surface of the insert 21. When the first plug-in portion 22 is inserted into the first plug-in interface 111 and the second plug-in portion 23 is inserted into the second plug-in interface 121, the insert 21 can cover the cutout 13 and make the outer surface of the insert 21 smoothly transition to the outer surfaces of the first profile 11 and the second profile 12, respectively.

[0027] Specifically, compared with the prior art, in the first aspect, by setting a first insertion interface 111 on the first profile 11 and a second insertion interface 121 on the second profile 12, and setting a cutout 13 between the first profile 11 and the second profile 12 that exposes the first insertion interface 111 and the second insertion interface 121; during the assembly of the corner protector 20, the first insertion part 22 is inserted into the first insertion interface 111 and the second insertion part 23 is inserted into the second insertion interface 121, so that the outer insert 21 covers the cutout 13 and completes the connection and fixation between the corner protector 20 and the first profile 11 and the second profile 12. This fixing method achieves mechanical connection, completely abandons the fixing method that relies on adhesives, fundamentally solves the technical defect of the corner protector 20 being easy to fall off in the traditional technology, thereby improving the connection strength of the corner protector 20. Firstly, the corner protectors extend the window sash 10's lifespan, ensuring continuous protection and eliminating safety hazards while enhancing the user experience. Secondly, after the first insertion part 22 is inserted into the first insertion interface 111 and the second insertion part 23 is inserted into the second insertion interface 121, the outer insert 21 can cover the cut 13 and smoothly transition its outer surface to the outer surfaces of the first profile 11 and the second profile 12, respectively. This solves the technical defect of the corner protectors 20 protruding from the profile surface in traditional technology. It not only improves the overall flatness of the window sash 10, making it more concise and aesthetically pleasing, but also ensures that when the window sash 10 is closed, it fits tightly against the window frame 30 without interference, thereby improving the window's sealing performance and ensuring that its sound insulation and heat preservation effects are not affected by the corner protectors 20.

[0028] In some embodiments, the first profile 11 extends horizontally, and the second profile 12 extends vertically; the second profile 12 is perpendicular to the first profile 11, and the right end of the first profile 11 is connected to the bottom of the second profile 12. A first insertion portion 22 is integrally formed on the left side of the insert 21 and extends to the left, while a second insertion portion 23 is integrally formed on the upper surface of the insert 21 and extends upward; the right side of the insert 21 has an arc-shaped surface 211, which, when the insert 21 covers the cutout 13, is tangent to the outer surfaces of the first profile 11 and the second profile 12. This structure, by providing the arc-shaped surface 211, allows for a seamless and smooth connection between the outer surface of the corner protector and the surfaces of the first profile 11 and the second profile 12, preventing the corner protector from protruding from the first profile 11 and the second profile 12, and further reducing the risk of collision damage through the arc-shaped surface 211.

[0029] Preferably, the front side of the insert 21 is integrally formed with a front corner protector 24, and the rear side of the insert 21 is provided with a rear corner protector 25; the dimensions of the front corner protector 24 and the rear corner protector 25 are smaller than the dimensions of the insert 21. By providing the front corner protector 24 and the rear corner protector 25, the side edges and corners of the window sash 10 can also be protected, realizing an all-round protection upgrade for the corners of the window sash 10. Moreover, the front corner protector 24 and the rear corner protector 25 do not need to be fixed with adhesive; the corner protectors 20 will not fall off simply by relying on the first insertion part 22 and the second insertion part 23, which have high connection strength.

[0030] Specifically, there are two first plug-in portions 22, which are spaced apart front to back and extend to the left; there are two second plug-in portions 23, which are spaced apart front to back and extend upward; both the first plug-in portions 22 and the second plug-in portions 23 are arranged in an "L" shape to form plug-in notches 221, with the plug-in notches 221 of the two first plug-in portions 22 facing each other, and the plug-in notches 221 of the two second plug-in portions 23 also facing each other. The width of the front-to-back distance between the two first plug-in portions 22 is smaller than the width of the plug-in notch 221 in the front-to-back direction, and the width of the front-to-back distance between the two second plug-in portions 23 is smaller than the width of the plug-in notch 221 in the front-to-back direction; the first plug-in portion 22 is interference-fitted with the first plug-in interface 111, and the second plug-in portion 23 is interference-fitted with the second plug-in interface 121. This structure, by providing at least two first insertion parts 22 and two second insertion parts 23, can form a multi-point support effect, which can effectively prevent the corner protector from loosening in all directions, thereby further enhancing the anti-fall-off effect of the corner protector; and the two first insertion parts 22 and second insertion parts 23, which are spaced apart, can be slightly deformed through the insertion notch 221 to generate clamping force, achieving an interference fit, ensuring that the insertion part can generate sufficient elastic deformation and recovery force after insertion, thereby tightly clamping the insertion part inside the profile, making the installation more secure.

[0031] In other embodiments, both the first profile 11 and the second profile 12 include an inner profile 1101, an outer profile 1102, and a heat insulation strip 1103. The inner profile 1101 and the outer profile 1102 are spaced apart front to back and are connected together by the heat insulation strip 1103. A first insertion interface 111 is provided on the heat insulation strip 1103 of the first profile 11, and a second insertion interface 121 is provided on the heat insulation strip 1103 of the second profile 12.

[0032] Specifically, it also includes a window frame 30, to which the window sash 10 is rotatably mounted; the inner profile 1101, the outer profile 1102, and the thermal break strip 1103 form an installation opening 1104 for installing the glass 40. A front guard edge 241 is provided at the front end of the front corner guard 24. When the window sash 10 is rotated and closed relative to the window frame 30, the front guard edge 241 can abut against the window frame 30. The front guard edge 241 contacts the window frame 30 when the window is closed, providing additional cushioning and reducing noise and impact from direct collisions between the window sash 10 and the window frame 30; simultaneously, the front guard edge 241 enhances the sealing at the corners of the window sash 10 and the window frame 30, thereby further improving the window's sealing performance.

[0033] More specifically, the corner protectors and heat insulation strip 1103 are made of any one of PA66GF25, PVC or PU.

[0034] It should be noted that PA66GF25 is glass fiber reinforced polyamide 66, PVC is polyvinyl chloride, and PU is polyurethane. Because the coefficient of thermal expansion of glass fiber reinforced polyamide 66 is very close to that of aluminum alloy, this means that when the temperature changes, the expansion and contraction of the thermal insulation strip 1103 and the aluminum alloy profile are basically the same. This avoids stress caused by asynchronous thermal expansion and contraction, preventing profile deformation, cracking, or connection failure. Therefore, PA66GF25 material is preferred.

[0035] The above are merely preferred embodiments of the present utility model, and only specifically describe the technical principles of the present utility model. These descriptions are only for explaining the principles of the present utility model and should not be construed as limiting the scope of protection of the present utility model in any way. Based on this explanation, any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model, as well as other specific embodiments of the present utility model that can be conceived by those skilled in the art without creative effort, should be included within the scope of protection of the present utility model.
