Description

Technical Field

[0001] This utility model relates to the field of window corner anti-collision technology, and in particular to a window corner anti-collision device. Background Technology

[0002] To prevent injuries from collisions with the corners of casement windows in daily life, various corner protectors have appeared on the market. These corner protectors act as a buffer when a person collides with the window corner, thus preventing injury. The corner protectors wrap around the corners of the window sash when the window is open to provide protection. When closing the window, users need to remove or move the corner protectors from the window sash to prevent them from interfering with the window sash and frame, thus ensuring the window closes properly.

[0003] In related technologies, Chinese invention patent CN1098882056B discloses a window corner protection device, including a mounting plate, a connecting structure, and a flexible anti-collision body. The mounting plate is installed on the surface of the window sash, the connecting structure is hinged to the mounting plate, and the flexible anti-collision body is disposed on the connecting structure. When the window is opened, the flexible anti-collision body covers the free end of the window corner of the window sash, and the side of the flexible anti-collision body near the window frame protrudes from the edge of the window sash. When the window is closed, the flexible anti-collision body can rotate relative to the mounting plate and the window sash, so after being subjected to the force of the window frame, it will be pushed away by the window frame and will not interfere with the window frame. In this way, the flexible anti-collision body is equivalent to being rotatably connected to the window sash, and when the window is closed, it is pushed away from the window frame by the window frame, thereby realizing the automatic lifting of the flexible anti-collision body when the window is closed.

[0004] However, these automatically lifting corner protectors only provide protection on three sides of the window corner, offering no protection for the side closest to the window frame. This results in insufficient protection for the window corner, increasing the likelihood of injury from collisions. Additionally, there are corner protectors on the market that provide protection on four sides. While this significantly enhances corner protection, it doesn't automatically lift when the window is closed, making it less convenient to use. Utility Model Content

[0005] The main purpose of this utility model is to propose a window corner anti-collision device, which aims to ensure the protective effect of the window corner anti-collision device while making the window corner anti-collision device automatically lift up when closing the window, so as to avoid obstructing the closing of the window between the window sash and the window frame.

[0006] To achieve the above objectives, this utility model proposes a window corner anti-collision device for protecting the corners of window sashes. The window corner anti-collision device includes:

[0007] The housing, wherein the housing is provided with an anti-collision groove for accommodating a window corner, the anti-collision groove includes at least a first sidewall and a second sidewall disposed opposite to each other, the first sidewall being used for rotatable connection with the window sash; and

[0008] An abutting protrusion is provided on one of the second sidewall and the window frame, and is used to abut against the other of the second sidewall and the window frame;

[0009] An abutment space is provided between the second sidewall and the first sidewall. The abutment space is used to provide space for the rotation of the housing. The abutment protrusion is provided corresponding to the abutment space.

[0010] In one embodiment, the abutment protrusion has a deformation space and an abutment surface. The deformation space is used to provide space for the deformation of the abutment protrusion. The abutment protrusion is connected to one of the second sidewall and the window frame. The abutment surface is used to abut against the other of the second sidewall and the window frame.

[0011] In one embodiment, the abutting protrusion includes a base and an abutting portion connected at an angle, the base being connected to one of the second sidewall and the window frame, the abutting portion having the abutting surface, and the deformation space being formed between the base and the abutting portion.

[0012] In one embodiment, the abutting protrusion includes a base, a connecting portion, and an abutting portion connected in sequence at an angle. The base is connected to one of the second sidewall and the window frame. One end of the connecting portion is connected to the base, and the abutting portion is connected to the other end of the connecting portion and is provided with the abutting surface. The base, the connecting portion, and the abutting portion enclose the deformation space.

[0013] In one embodiment, the cross-sectional area of ​​the base gradually decreases from the end furthest from the connecting portion to the end closest to the connecting portion;

[0014] And / or, the cross-sectional area of ​​the abutting portion gradually decreases from the end closer to the connecting portion to the end farther away from the connecting portion.

[0015] In one embodiment, the anti-collision groove further includes a bottom wall and a third side wall connecting the first side wall and the second side wall, and the avoidance space and the abutment protrusion are disposed close to the bottom wall and the third side wall.

[0016] In one embodiment, the opening of the deformation space is oriented in the same direction as the opening of the anti-collision groove.

[0017] In one embodiment, the contact surface is arc-shaped;

[0018] And / or, the abutment protrusion is made of an elastic material.

[0019] In one embodiment, the abutment protrusion and the housing are detachably connected;

[0020] And / or, the second sidewall is provided with a positioning groove, and at least a portion of the abutment protrusion is limited to the positioning groove;

[0021] And / or, the end of the abutting protrusion near the second sidewall is provided with a connecting post, the second sidewall is provided with a connecting hole, and the connecting post is installed in the connecting hole.

[0022] In one embodiment, the window corner anti-collision device further includes a mounting plate for connecting to the window sash, and the first sidewall is rotatably connected to the mounting plate;

[0026] The corner protection device of this utility model protects the window corner by positioning the corner within the anti-collision groove of the housing, allowing the housing to enclose the corner. When a user accidentally bumps into the corner, the housing acts as a buffer, preventing injury. The first sidewall of the anti-collision groove is rotatably connected to the window sash. By rotating the housing, it can be flipped outwards, allowing the corner to disengage from the anti-collision groove and preventing the corner protection device from interfering with the normal closure of the window sash. An abutment protrusion is provided between the second sidewall and the window frame. This abutment protrusion can be located on the second sidewall and abut against the window frame during closing. As the window sash approaches the frame, the frame pushes the abutment protrusion, causing the housing to rotate and flip outwards, disengaging the corner from the anti-collision groove. With the housing no longer between the window sash and frame, the window sash can close normally. Alternatively, the abutment protrusion can be located on the window frame and abut against the second sidewall during closing. As the window sash approaches the frame, the abutment protrusion pushes the housing, causing it to rotate and flip outwards, allowing the window sash to close normally. The second sidewall protects the corner of the window near the window frame. A clearance space is provided between the first and second sidewalls to prevent the window sash from offsetting the force of the abutment protrusion on the second sidewall, thus preventing the abutment protrusion from causing the casing to flip outwards. In this way, the casing automatically flips outwards when the user closes the window, avoiding interference between the window sash and the window frame. Attached Figure Description

[0041] Please refer to the reference. Figures 1 to 7 As shown, this utility model proposes a window corner anti-collision device 100 for the protection of the window corner of a window sash 4. The window corner anti-collision device 100 includes a housing 1 and an abutment protrusion 2. The housing 1 is provided with an anti-collision groove 15 for accommodating the window corner. The anti-collision groove 15 includes at least a first side wall 11 and a second side wall 12 arranged opposite to each other. The first side wall 11 is used to rotatably connect with the window sash 4. The abutment protrusion 2 is provided on one of the second side wall 12 and the window frame 5 and is used to abut against the other of the second side wall 12 and the window frame 5. A clearance space 16 is provided between the second side wall 12 and the first side wall 11. The clearance space 16 is used to provide space for the rotation of the housing 1. The abutment protrusion 2 is provided corresponding to the clearance space 16.

[0042] A window typically includes a fixed window frame 5 and a rotatable window sash 4. When the corner protection device 100 protects the corner of the window sash 4, the corner is located within the anti-collision groove 15 of the housing 1, allowing the housing 1 to enclose the corner. When a user accidentally bumps into the corner, the housing 1 acts as a buffer, preventing injury. The first sidewall 11 of the anti-collision groove 15 can be rotatably connected to the window sash 4. By rotating the housing 1, it can be flipped outwards, allowing the corner to disengage from the anti-collision groove 15, preventing the corner protection device 100 from interfering with the normal closing of the window sash 4.

[0043] Understandably, to allow the housing 1 to automatically flip outwards during window closing, an abutment protrusion 2 is provided between the second side wall 12 and the window frame 5. The abutment protrusion 2 can be located on the second side wall 12, abutting against the window frame 5 during closing. As the window sash 4 approaches the window frame 5, the window frame 5 pushes the abutment protrusion 2, causing the housing 1 to rotate and flip outwards, allowing the window corner to disengage from the anti-collision groove 15. With the housing 1 no longer between the window sash 4 and the window frame 5, the window sash 4 can close normally. Alternatively, the abutment protrusion 2 can be located on the window frame 5, abutting against the second side wall 12 during closing. As the window sash 4 approaches the window frame 5, the abutment protrusion 2 pushes the housing 1, causing it to rotate and flip outwards, thus allowing the window sash 4 to close normally. A clearance space 16 is provided between the first sidewall 11 and the second sidewall 12, and the abutment protrusion 2 is provided corresponding to the clearance space 16. The existence of the clearance space 16 ensures that the abutment force transmitted or applied by the abutment protrusion 2 to the second sidewall 12 is not offset by the force exerted by the window sash 4 on the second sidewall 12, allowing the shell 1 to be subjected to rotational torque and fold outward. At the same time, the clearance space 16 can also avoid the rotation trajectory of the second sidewall 12, preventing the window sash 4 from obstructing the movement of the second sidewall 12.

[0044] Understandably, since the angle between the window sash 4 and the window frame 5 is very small after they approach each other, the direction of the force exerted by the window frame 5 on the abutment protrusion 2 is approximately perpendicular to the second side wall 12. If there is no clearance space 16, the force transmitted by the abutment protrusion 2 on the second side wall 12 will be canceled out by the force exerted by the window sash 4 on the second side wall 12, making it difficult for the housing 1 to flip outward. In actual implementation, the force transmitted by the abutment protrusion 2 on the housing 1 is at a certain distance from the rotation axis of the housing 1 and the window sash 4 to generate a torque, allowing the housing 1 to rotate. Generally speaking, the corner anti-collision device 100 is applied to the bottom of the window sash 4. Therefore, the abutment protrusion 2 is positioned closer to the bottom of the window sash 4 than the rotation axis of the housing 1 and the window sash 4, so that the force transmitted or applied by the abutment protrusion 2 on the window sash 4 can drive the housing 1 to flip outward.

[0045] Optionally, the clearance space 16 is located within the anti-collision groove 15. When the window corner is inserted into the anti-collision groove 15, due to the irregular structure of the window corner itself, the window sash 4 has a protruding sidewall on the side away from the window frame 5 in order to cover the window opening of the window frame 5. This sidewall abuts against the outer wall surface of the window frame 5 when the window is closed. Therefore, the anti-collision groove 15 is not completely filled by the window corner, and a clearance space 16 is left between the window corner and the housing 1. This prevents the second sidewall 12 from completely abutting against the window sash 4, thus avoiding the window sash 4 from obstructing the abutment protrusion 2 from pushing the second sidewall 12 to cause the housing 1 to flip outward. At the same time, the clearance space 16 between the window corner and the housing 1 can also improve the cushioning effect of the housing 1 during a collision.

[0046] In actual implementation, the window corner generally has four sides, two of which are perpendicular to the thickness direction of the window sash 4, and the other two are parallel to the thickness direction of the window sash 4. The first sidewall 11 and the second sidewall 12 of the anti-collision groove 15 correspond to wrapping the two sides of the window corner perpendicular to the thickness direction of the window sash 4. The anti-collision groove 15 is also provided with a third sidewall 13 and a bottom wall 14 connecting the first sidewall 11 and the second sidewall 12. The third sidewall 13 and the bottom wall 14 correspond to wrapping the two sides of the window corner parallel to the thickness of the window sash 4. The anti-collision groove 15 is approximately cubic in shape, so the first sidewall 11, the second sidewall 12, the third sidewall 13, and the bottom wall 14 can be equivalent to different sidewalls of a cube. The outward turning of the shell 1 refers to the rotation of the shell 1 relative to the window sash 4 in a direction away from the window corner.

[0047] Optionally, the shell 1 can be made of a flexible material such as rubber or silicone, which has a certain elastic deformation capability and plays a cushioning role. The first side wall 11 and the window sash 4 can be connected by a rotating structure such as a hinge or a pivot.

[0048] In embodiments of this utility model, such as Figures 1 to 7 As shown, the abutment protrusion 2 is provided with a deformation space 24 and an abutment surface 231. The deformation space 24 is used to provide space for the deformation of the abutment protrusion 2. The abutment protrusion 2 is connected to one of the second side wall 12 and the window frame 5. The abutment surface 231 is used to abut against the other of the second side wall 12 and the window frame 5.

[0049] In actual implementation, when the abutment protrusion 2 is connected to the second side wall 12, the deformation space 24 is located between the second side wall 12 and the abutment surface 231. When the abutment protrusion 2 is connected to the window frame 5, the deformation space 24 is located between the window frame 5 and the abutment surface 231.

[0050] In this embodiment, the deformation space 24 is provided so that when the abutting protrusion 2 presses against the second side wall 12 or the window frame 5, the abutting protrusion 2 will bend or bend towards the deformation space 24, thereby applying or transmitting a force opposite to the deformation direction to the second side wall 12. This force not only has a component force perpendicular to the second side wall 12, but also a component force parallel to the second side wall 12, which makes it easier to drive the housing 1 to rotate outward and improve the stability of the automatic outward tilting function of the window corner anti-collision device 100.

[0051] Understandably, the deformation space 24 is designed so that when the abutting protrusion 2 presses against the window frame 5 or the second side wall 12, it bends and deforms in a predetermined direction, thereby enabling the force applied to or transmitted to the second side wall 12 in a predetermined direction to drive the housing 1 to rotate outward.

[0052] Understandably, at the initial stage of the outward rotation of the housing 1, the second sidewall 12 needs to move approximately parallel to the window sash 4, which is equivalent to the second sidewall 12 translating along its own plane. Therefore, applying or transmitting a force parallel to the second sidewall 12 to the second sidewall 12 is beneficial for the outward rotation of the housing 1. Taking the embodiment where the abutting protrusion 2 is connected to the second sidewall 12 as an example, when the abutting protrusion 2 first abuts against the window frame 5, the direction of the force transmitted by the abutting protrusion 2 to the second sidewall 12 is approximately perpendicular to the second sidewall 12. As the window sash 4 moves further closer to the window frame 5, the abutting protrusion 2 will bend and deform towards the deformation space 24. At this time, the window frame 5 exerts both supporting force and frictional force on the abutting protrusion 2. Correspondingly, the force transmitted by the abutting protrusion 2 to the second sidewall 12 has both a component perpendicular to the second sidewall 12 and a component parallel to the second sidewall 12, further reducing the difficulty of the housing 1 rotating outward. The force transmitted by the abutment protrusion 2 to the second side wall 12 is inclined to the plane of the window sash 4. In this way, by setting the deformation space 24, the abutment protrusion 2 can apply a force to the second side wall 12 that is inclined or parallel to the window sash 4, so that the second side wall 12 can move outward around the window sash 4, and the shell 1 can be more easily rotated outward.

[0053] In another embodiment of this utility model, such as Figure 7 As shown, the abutting protrusion 2 includes a base 21 and an abutting part 23 connected at an angle. The base 21 is connected to one of the second side wall 12 and the window frame 5. The abutting part 23 is provided with an abutting surface 231. A deformation space 24 is formed between the base 21 and the abutting part 23.

[0054] In this embodiment, the base 21 serves as a support structure for the abutment protrusion 2, ensuring stability when the abutment protrusion 2 deforms. One end of the base 21 is connected to one end of the abutment portion 23, and the other end of the base 21 and the other end of the abutment portion 23 are spaced apart, so that a deformation space 24 is formed between the abutment portion 23 and the second sidewall 12. It can be understood that the included angle between the base 21 and the abutment portion 23 is an acute angle, so that the abutment portion 23 deforms towards the deformation space 24 after being pressed.

[0055] In actual implementation, the base 21 and the contact part 23 can be arranged in a V-shape, and no specific limitation is made here.

[0056] In one embodiment of this utility model, such as Figure 3 As shown, the abutting protrusion 2 includes a base 21, a connecting part 22 and an abutting part 23 connected in sequence at an angle. The base 21 is connected to one of the second side wall 12 and the window frame 5. One end of the connecting part 22 is connected to the base 21, and the abutting part 23 is connected to the other end of the connecting part 22 and is provided with an abutting surface 231. The base 21, the connecting part 22 and the abutting part 23 enclose and form a deformation space 24.

[0057] In this embodiment, the abutting part 23 is connected to the base 21 via the connecting part 22 and is spaced apart from the base 21, thus forming a deformation space 24 between the abutting part 23 and the base 21. Optionally, the base 21, the connecting part 22, and the abutting part 23 are arranged in a U-shape, which is not specifically limited here.

[0058] Optionally, the abutment protrusion 2 can be generally columnar, with the abutment portion 23 and the base 21 coaxially arranged, and the connecting portion 22 located on one side of the central axis of the abutment protrusion 2. The axial direction of the abutment protrusion 2 can be perpendicular to the outer surface of the second side wall 12 or the window frame 5. Optionally, the projection of the deformation space 24 in the direction perpendicular to the axial direction of the abutment protrusion 2 exceeds the axis of the abutment protrusion 2, so that the abutment protrusion 2 can be more easily bent toward the deformation space 24.

[0059] Optionally, the cross-sectional area of ​​the base 21 gradually decreases from the end away from the connecting portion 22 to the end closer to the connecting portion 22. In this embodiment, the cross-sectional area of ​​the base 21 away from the connecting portion 22 is large to improve the stability of the connection between the abutting protrusion 2 and the second sidewall 12 or the window frame 5. Optionally, the cross-sectional area of ​​the abutting portion 23 gradually decreases from the end closer to the connecting portion 22 to the end away from the connecting portion 22. This makes it easier for the abutting portion 23 to deform in the direction of the deformation space 24, and the abutting protrusion 2 as a whole undergoes bending deformation.

[0060] In actual implementation, the abutment protrusion 2 can be approximately cone-shaped or frustum-shaped, without specific limitations.

[0061] In one embodiment of this utility model, such as Figures 1 to 3 As shown, the anti-collision groove 15 also includes a bottom wall 14 and a third side wall 13 connecting the first side wall 11 and the second side wall 12, an avoidance space 16 and an abutment protrusion 2 disposed near the bottom wall 14 and the third side wall 13.

[0062] In this embodiment, the bottom wall 14, the third side wall 13, the window sash 4 and the second side wall 12 enclose and form a clearance space 16. The abutment protrusion 2 is provided on the side of the second side wall 12 away from the clearance space 16, so as to avoid the force of the abutment protrusion 2 on the second side wall 12 being offset by the force of the window sash 4 on the second side wall 12, so that the housing 1 can rotate relative to the window sash 4.

[0063] In actual implementation, the rotational connection between the first sidewall 11 and the window sash 4 is located on the side away from the third sidewall 13 and the bottom wall 14. The rotational axis of the first sidewall 11 and the window sash 4 is set at an angle with the plane where the bottom wall 14 and the third sidewall 13 are located. The angle can be 45° to extend the lever arm of the abutment protrusion 2 and the rotational axis, so as to facilitate the outward rotation of the housing 1.

[0064] In one embodiment of this utility model, such as Figures 1 to 3As shown, the opening of the deformation space 24 faces the same direction as the groove of the anti-collision groove 15.

[0065] In this embodiment, the groove of the anti-collision groove 15 faces away from the bottom wall 14 and the third side wall 13, and the opening of the deformation space 24 is also set towards the side away from the bottom wall 14 and the third side wall 13. When the abutting protrusion 2 presses against the window frame 5 or the second side wall 12, it will also bend away from the bottom wall 14 and the third side wall 13. The abutting protrusion 2 will then exert a force on the second side wall 12 that is transmitted towards the bottom wall 14 and the third side wall 13, thereby causing the housing 1 to flip outward away from the window sash 4.

[0066] Understandably, the orientation of the opening of the deformation space 24 is perpendicular to the rotation axis that connects the first side wall 11 and the window sash 4, and the bending deformation direction of the abutment protrusion 2 is perpendicular to the rotation axis, so that the torque applied or transmitted by the abutment protrusion 2 to the second side wall 12 is greater, thereby reducing the difficulty of the housing 1 rotating around the rotation axis.

[0067] In one embodiment of this utility model, such as Figures 1 to 3 As shown, the abutment surface 231 is arc-shaped; in this embodiment, the abutment surface 231 is arc-shaped to reduce the frictional resistance when moving relative to the window frame 5, making it easier for the abutment protrusion 2 to slide along the window frame 5.

[0068] Optionally, the abutment protrusion 2 is made of an elastic material. This allows the abutment protrusion 2 to undergo elastic deformation, such as elastic compression or elastic bending, when it abuts against the window frame 5, thereby causing the housing 1 to rotate outward. In actual implementation, the abutment protrusion 2 can be made of elastically deformable materials such as rubber or plastic.

[0069] In one embodiment of this utility model, the abutment protrusion 2 and the housing 1 are detachably connected. For example... Figure 3 As shown, the second sidewall 12 is provided with a positioning groove 121, and at least part of the protrusion 2 is limited to the positioning groove 121.

[0070] In this embodiment, the limiting cooperation between the abutment protrusion 2 and the positioning groove 121 achieves positioning and installation, while preventing relative displacement of the abutment protrusion 2 relative to the second side wall 12, which would affect the stability and reliability of the window frame 5 pushing the abutment protrusion 2 to drive the housing 1 to rotate around the window sash 4. Optionally, the abutment protrusion 2 and the second side wall 12 can be integrally formed.

[0071] Optionally, a connecting post 25 is provided at one end of the abutment protrusion 2 near the second sidewall 12, and the second sidewall 12 is provided with a connecting hole 122, with the connecting post 25 installed in the connecting hole 122. In this embodiment, the abutment protrusion 2 and the second sidewall 12 are detachably connected through the cooperation of the connecting post 25 and the connecting hole 122, so as to facilitate the replacement of the abutment protrusion 2. In actual implementation, the connecting post 25 and the connecting hole 122 can be connected by a threaded engagement. Optionally, the connecting hole 122 can also be provided through the second sidewall 12, and the connecting post 25 is provided with a threaded hole, with the connecting post 25 passing through the connecting hole 122. A screw is connected to the threaded hole from the side of the connecting hole 122 facing away from the abutment protrusion 2, so that the abutment protrusion 2 is connected to the second sidewall 12. Optionally, the connecting post 25 is connected to the connecting hole 122 by a rivet. In actual implementation, the connecting post 25 is provided at the bottom of the positioning groove 121.

[0072] Alternatively, the abutment protrusion 2 and the housing 1 can also be integrally formed, such as by integral injection molding.

[0073] In one embodiment of this utility model, such as Figures 1 to 7 As shown, the window corner anti-collision device 100 also includes a mounting plate 3, which is used to connect with the window sash 4, and the first side wall 11 is rotatably connected to the mounting plate 3.

[0074] In this embodiment, the mounting plate 3 is connected to the window sash 4, and the position of the mounting plate 3 is fixed relative to the position of the window sash 4. The first side wall 11 is rotatably connected to the mounting plate 3.

[0075] In practical implementation, the mounting plate 3 can be connected to the window sash 4 by means of adhesive, snap-fit, or screw connection. The first side wall 11 is then rotatably connected to the mounting plate 3 through the cooperation of a hinge or pivot and pivot hole, thus achieving the rotatable connection between the first side wall 11 and the window sash 4. Optionally, a torsion spring can be installed on the hinge or pivot. When the housing 1 is tilted outward, the torsion spring is in a deformed state. When the external force is removed from the housing 1, the torsion spring will automatically rebound, causing the housing 1 to rotate inward, so that the housing 1 automatically wraps around the window corner. Thus, when the window is closed, the housing 1 automatically tilts outward, and when the window is fully closed, it is obstructed by the window frame 5 to maintain the tilted state. When the window is opened, the housing 1 will automatically rotate inward, automatically protecting the window corner. Magnetic attraction components can be installed between the first side wall 11 and the mounting plate 3 to attract each other, improving the stability of the window corner anti-collision device 100 when protecting the window corner.

[0076] In one embodiment of this utility model, the abutting protrusion 2 can be directly set as an elastic structure, such as a spring, elastic soft rubber, etc., and no deformation space 24 is provided; optionally, the abutting protrusion 2 can be set as one or more.

[0077] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
