[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the utility model will be further described in detail below with reference to the accompanying drawings. The components of the embodiments of this utility model described and shown in the accompanying drawings can be arranged and designed in various different configurations. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0027] like Figure 1-7 As shown, a window corner protector includes a first corner protector 10 and a second corner protector 20. The first corner protector 10 is used to install onto a window sash, for example, by adhesive bonding. The second corner protector 20 is movable relative to the first corner protector 10 to form an anti-collision state or an unlocked state, wherein the anti-collision state is as follows: Figure 1 As shown, at this time, the second corner protector 20 can completely or partially wrap around the window corner to be protected, thus achieving the function of anti-collision. That is, the cushioning effect of the material of the second corner protector 20 prevents the user from directly hitting the window corner and causing injury; in the unlocked state, it can be like... Figure 7 As shown, to adapt to the closing of the window sash, that is, in the unlocked state, the second corner guard 20 can move accordingly as the window sash needs to be closed to avoid interference with the window frame.

[0028] A locking mechanism is provided between the first corner protector 10 and the first wall portion 21, such as... Figure 2-5 As shown, the locking mechanism acts between the two corner protectors, locking or unlocking the second corner protector 20 relative to the first corner protector 10. This ensures that the second corner protector 20 continuously wraps around the window corner during the anti-collision state, providing continuous anti-collision protection and enhancing safety. It should be noted that the window sash cannot be closed at this time because the second corner protector 20 will interfere with the window frame, and the locking structure does not allow the second corner protector 20 to move. When it is necessary to close the window, the user operates the locking mechanism to unlock it, releasing its locking effect on the second corner protector 20. The second corner protector 20 can then detach from the window corner under its own weight or be pushed away from the window corner by contact with the window frame, allowing the window sash to be closed. For example, as shown... Figure 7 As shown.

[0029] The second corner protector 20 includes a first wall portion 21 and a second wall portion 22 disposed on one side of the first wall portion 21. A flexible wall 210 for fixing to the first corner protector 10 is formed at the upper end of the first wall portion 21. The flexible wall 210 is made of a flexible material and is shaped like a thin-walled sheet, thereby allowing the second corner protector 20 to move due to its flexibility. Therefore, the flexible wall 210 fixes the two corner protectors together to form an integral structure for easy installation and use. On the other hand, the flexibility of the flexible wall 210 enables the second corner protector 20 to move relative to the first corner protector 10 to form an anti-collision state or an unlocked state.

[0030] Furthermore, the second corner protector 20 is composed of the first component 211 and the second component 212, as follows: Figure 6 As shown, the second component 212 is fixed to the inner wall of the first component 211 or is wrapped inside the first component 211, and the hardness of the second component 212 is greater than that of the first component 211. This can be achieved by configuring the two components to be made of materials with different hardnesses. For example, the first component 211 can be a soft component (i.e., a soft plastic part, such as a rubber part), and the second component 212 can be a hard component (i.e., a hard plastic part). Configuring the second component 212 as a hard component can ensure that the locking mechanism has good locking strength in the anti-collision state, preventing the locking mechanism from being accidentally unlocked due to external force pulling or collision, thereby improving safety.

[0031] Preferably, the rigid plastic part is fixed to the inner wall of the soft plastic part by injection molding, that is, they are integrally injection molded (i.e., injection molding connection) to simultaneously form the first component 211 and the second component 212. This has a better connection structure and strength. Of course, it is also feasible to mold the two separately and then fix them together (the fixing connection can be snap-fit, hot melt connection, ultrasonic welding or adhesive connection, etc., all of which are known technologies).

[0032] In this embodiment, the first component 211 includes a first domain 213 and a second domain 214 preferably disposed perpendicular to the first domain 213 and located on one side thereof. The second component 212 includes a third domain 215 and a fourth domain 216 preferably disposed perpendicular to the third domain 215 and located on one side thereof. The third domain 215 extends from the lower end of the first domain 213 toward the middle, and the fourth domain 216 extends from the inner end of the second domain 214 toward the middle, so that the window corner anti-collision member has high structural strength and hardness at the connection between the first wall portion 21 and the second wall portion 22, thereby providing good anti-collision effect and product shaping effect. Therefore, the first wall portion 21 is composed of the first domain portion 213 and the third domain portion 215, and the second wall portion 22 is composed of the second domain portion 214 and the fourth domain portion 216.

[0033] The first component 211 is a one-piece molded flexible sheet component, and the portion of its upper end without the third domain 215 forms the flexible wall 210. A fixing part 203, such as a fixing hole, is provided on the flexible wall 210 to fix the first component 211 to the first corner protector 10. Furthermore, the switching between the anti-collision and unlocking states of the second corner protector 20 is also achieved based on the flexible wall 210.

[0034] Preferably, the second component 212 is disposed on the inner surface of the first component 211 or is enclosed within the first component 211, such that the first component 211 is disposed on the outer surface of the second corner protector 20, thereby providing a good cushioning and impact protection effect. (Reference) Figure 6 The first component 211 is configured to enclose the second component 212 inside it, that is, the second component 212 is pre-formed and placed in the molding mold of the first component 211, and then the first component 211 is injection molded so that they are integrally formed.

[0035] Preferably, the first component 211 further includes a fifth domain 218 connected to the second domain 214 and disposed parallel to the first domain 213, such as... Figure 6 As shown. The fifth domain 218 is preferably formed by further extending the second domain 214 of the first member 211, and is made of a flexible material, used to protect the outer surface of the window sash in an anti-collision state.

[0036] In this embodiment, both the second domain 214 and the fourth domain 216 include two mutually perpendicular surfaces, and the upper edge of the third domain 215 is flush with the line connecting the outer ends of the two surfaces of the second domain 214. This allows for simultaneous protection of the bottom and sides of the window sash, enhancing security. In other embodiments, one of the domains may have two mutually perpendicular surfaces, or one may have only one surface for protection at the bottom edge of the window sash.

[0037] Preferably, a protrusion 205 is provided on the inner surface of the first member 211, such as... Figure 5 As shown, the protrusion 205 is provided around the fixing part 203 and extends downward, so as to enhance the structural strength of the fixing hole serving as the fixing part 203 and prevent product damage caused by damage to the fixing hole. (Reference) Figure 5 As shown, the protrusion 205 is arranged around the fixing hole and extends downward integrally to improve the structural strength of the fixing hole.

[0038] The fixing part 203 and the upper edge of the third domain part 215 are provided at a predetermined distance d, such as... Figure 6 As shown, the predetermined spacing d can be 1-6 cm, or it can be 20-50% of the length of the first domain 213 (referring to the length of the first domain 213 in the vertical direction, for reference). Figure 2 (as shown in the direction). Furthermore, the length of the fourth domain 216 can be configured to be 30-70% of the length of the second domain 214 (referring to the length of the second domain 214 in the inward and outward directions, reference). Figure 2 (as shown in the direction), thus achieving the best overall protection and cost.

[0039] Preferably, the second domain 214 is provided with a plurality of protruding ribs 217 on the outer side of the fourth domain 216, such as Figure 5 As shown, this is used to improve the shape stability and increase the buffer of the second domain 214, which does not have a fourth domain 216.

[0040] In this embodiment, as Figure 2-5 As shown, the locking mechanism includes a first locking mechanism 13 and a second locking mechanism 25 respectively disposed on the first corner protector 10 and the second component 212, for locking or unlocking the movement of the second corner protector 20. The second locking mechanism 25 is disposed on the third domain 215 to ensure a secure locking structure when the corner protector is in its anti-collision state.

[0041] The first locking mechanism 13 includes a locking tongue 131 and an unlocking button 132. The unlocking button 132 and the locking tongue 131 are respectively movably arranged in a direction perpendicular to the first corner guard 10 and in a direction parallel to the first corner guard 10. At least one of the locking tongue 131 and the unlocking button 132 is provided with a guide surface 134, so that pressing the unlocking button 132 can drive the locking tongue 131 to extend and retract, thereby separating or engaging the first locking mechanism 13 and the second locking mechanism 25 to realize the unlocking or locking function of the locking mechanism.

[0042] In this embodiment, as Figure 4As shown, the first corner protector 10 includes a main fixing member 11 and a secondary fixing member 12. The fixing post 121 of the secondary fixing member 12 passes through the fixing part 203 of the first wall part 21. The secondary fixing member 12 is fixedly connected to the main fixing member 11. For example, it can be connected to the fixing post 121 by threading a screw (not shown in the figure) through the through hole 113. In other embodiments, the fixing post 121 and the main fixing member 11 can also be fixed by snapping or heat welding.

[0043] like Figure 4 As shown, the main fixing member 11 includes an upper body 111 and a lower body 112. The fixing post 121 passes through the fixing part 203 and is fixedly connected to the upper body 111. The lower body 112 is provided with a locking tongue seat 114 arranged in the vertical direction. A locking tongue member 131 and an unlocking button 132 are arranged in the locking tongue seat 114. The locking tongue member 131 is arranged in a direction parallel to the first corner guard member 10, and the unlocking button 132 is arranged in a direction perpendicular to the first corner guard member 10. Thus, by pressing the unlocking button 132 in the direction perpendicular to the first corner guard member 10, the locking tongue member 131 is driven to retract in the direction parallel to the first corner guard member 10, so that the tongue end 133 at the front end of the locking tongue member 131 separates from the second locking mechanism 25 and unlocks.

[0044] Among them, such as Figure 5 As shown, a hole 219 is provided on the third domain 215, and a tongue hole is provided on the lower side wall of the hole 219. This tongue hole forms a second locking mechanism 25. When the tongue tip 133 enters the tongue hole, it locks the second corner guard 20; when it disengages, it unlocks. Providing the tongue hole on the lower side wall of the hole 219 increases the locking strength of the locking structure and reduces the possibility of accidental unlocking due to violent pulling. In other embodiments, the tongue hole can also be provided on the left, right, or upper side walls of the hole 219.

[0045] As a preferred option, such as Figure 1-3 As shown, the area where the first domain 213 is integrated and covers the hole 219 is provided to form a button area 202 on the outer surface of the first domain 213. Since the first domain 213 is made of a soft material, it can be pressed to drive the unlock button 132 to unlock. At the same time, the first domain 213 has an integrated structure on its outer surface, which can prevent children from operating it and improve safety.

[0046] As a preferred option, such as Figure 2 As shown, a cavity 204 is provided on the outer surface of the first domain 213 to accommodate all or part of the secondary fastener 12 so that the secondary fastener 12 does not protrude too much from the surface of the first domain 213 after assembly.
