Description

Technical Field

[0001] This application relates to the field of door and window component technology, and in particular to a window and door handle that is not slippery. Background Technology

[0002] Window and door handles are lever structures located outside the window and door lock body, used to control the opening and closing of the window and door lock body. Under normal circumstances, the surface is relatively smooth and the grip is comfortable. However, after the window and door are opened and then rained on, a water film adheres to the surface, greatly reducing the coefficient of friction. Especially for window and door handles that open outwards, the distance may be relatively far, making it difficult for the operator to fully grasp the handle, which can easily cause slippage and make closing the window difficult. Utility Model Content

[0003] The purpose of this application is to provide a window handle that is easier to close and less prone to slipping.

[0004] To achieve the above objectives, this application provides a non-slip window handle: including a cantilever, a friction strip on one side of the cantilever, a silicone pad on the opposite side of the friction strip, a handle at one end of the cantilever located on the side of the silicone pad, and a hook at the other end of the cantilever, the hook being bent toward the side of the handle, so that when closing the window, simply hooking the hook will drive the entire window to complete the closing action.

[0005] As a preferred embodiment, the end of the handle facing away from the cantilever has an anti-rotation block, the geometric center line of which is collinear with the axis of the handle, for use in conjunction with the lock cylinder structure of the window / door.

[0006] As a preferred embodiment, the end face of the anti-rotation block is provided with a through hole that passes through the rotating handle, and the side of the rotating handle is provided with a relief groove that communicates with the through hole, allowing bolts and other connecting parts to pass through.

[0007] As a preferred embodiment, the relief groove is coaxial with the through hole, and the inner diameter of the relief groove is larger than the inner diameter of the through hole, in order to accommodate the larger end of the bolt.

[0008] As a preferred embodiment, the side of the cantilever is also provided with a recessed cap groove coaxial with the relief groove. The inner wall of the recessed cap groove has a coaxial retaining ring to restrain the plastic cap inside the recessed cap groove, thereby preventing rainwater and dust from entering the relief groove.

[0009] As a preferred embodiment, the anti-rotation block, the handle, and the hook are integrally formed with the cantilever, which features uniform material and stable structure.

[0010] As a preferred embodiment, the friction strip and silicone pad are provided on the other two sides of the cantilever, making it more difficult for the cantilever to move towards the end after the operator grips the cantilever.

[0011] As a preferred embodiment, the silicone pad is fixedly connected to the cantilever by a curing adhesive, and the surface of the silicone pad facing away from the cantilever has friction grooves to further enhance the friction of the grip handle.

[0012] Compared with the prior art, the beneficial effects of this application are as follows:

[0013] (1) By setting a hook structure that bends toward the window frame at the end of the window handle, it effectively prevents the operator's palm or even fingers from slipping, making it easier to close windows that open outwards and have handles that are far away.

[0014] (2) By setting friction strips on the front of the handle and silicone pads with friction grooves on the back of the handle, the contact friction between the handle and the operator's handle is effectively increased, making it less likely to slip when operating and gripping the handle, and improving the stability of operation.

[0024] The terms “comprising” and “having”, and any variations thereof, in the specification and claims of this application are intended to cover non-exclusive inclusion, for example, a process, method, system, product, or device that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or device.

[0025] like Figure 1-5 The non-slip window / door handle shown includes a cantilever 1 with one end rotated and constrained. The cantilever 1 can only rotate around the constrained end. One side of the cantilever 1 has a friction strip 105, which protrudes from the surface of the cantilever 1 and typically comes into direct contact with the palm to increase friction with the operator's hand. The opposite side of the friction strip 105 has a silicone pad 5, made of skin-friendly silicone material, which itself has a high coefficient of friction and typically comes into direct contact with the fingertips. Because the silicone pad 5 and the cantilever 1 are made of different materials, [the following text is incomplete and requires further context to translate accurately]. The silicone pad 5 is fixedly connected to the cantilever 1 by using a curing adhesive. The surface of the silicone pad 5 facing away from the cantilever 1 is also provided with a friction groove 501 to further increase the friction between the silicone pad 5 and the operator's hand. The cantilever 1 is provided with a friction strip 105 and the silicone pad 5 has waist-shrinking grooves 101 on the other two sides. The friction strip 105 is usually located on the front of the cantilever 1, the silicone pad 5 is located on the back of the cantilever 1, and the waist-shrinking grooves 101 are located on the left and right sides of the cantilever 1, so that the two ends of the cantilever 1 are wider and the closer to the middle is narrower. In this way, when the operator grips the cantilever 1 tightly, it is not easy for the cantilever 1 to slip towards the end.

[0026] One end of the cantilever 1 has a handle 3, which protrudes from the back of the cantilever 1. That is, the handle 3 is located on the side where the silicone pad 5 is located. The end of the handle 3 facing away from the cantilever 1 has an anti-rotation block 4, which is used to engage with the lock cylinder of the door and window. The geometric center line of the anti-rotation block 4 is collinear with the axis of the handle 3, which can effectively transmit torque, thereby driving the lock cylinder of the door and window to move. The end face of the anti-rotation block 4 has a through hole 34 that passes through the handle 3, allowing bolts and other connecting parts to pass through, so as to fix the window and door handle and the door and window lock cylinder linkage components. The side of the handle 3 has a relief groove 102 that communicates with the through hole 34. The relief groove 102 is coaxial with the through hole 34, and the inner diameter of the relief groove 102 is larger than the inner diameter of the through hole 34, which is used to accommodate the larger end of the bolt.

[0027] The side of the cantilever 1 is also provided with a recessed cap groove 103 coaxial with the relief groove 102, which is used to install a plastic cover, to cover the connecting structure inside the relief groove 102, and to prevent water or dust from accumulating inside the relief groove 102. The inner wall of the recessed cap groove 103 has a coaxial retaining ring 104, which is used to engage with the groove structure on the side of the plastic cover, thereby ensuring the stability of the plastic cover installation and facilitating disassembly and assembly. The plastic cover is usually also marked with product information such as the manufacturer or product model.

[0028] The other end of the cantilever 1 has a hook 2. The hook 2 has an arc-shaped part and is tangent to the extension direction of the cantilever 1. The hook 2 bends toward the side where the handle 3 is located to prevent the four fingers located behind the cantilever 1 from sliding out along the extension direction of the cantilever 1, thereby effectively improving the anti-slip performance of the door handle. The anti-rotation block 4, handle 3 and hook 2 are integral structures with the cantilever 1. They are usually made of corrosion-resistant alloy materials, such as aluminum alloy or stainless steel, or steel, and then sprayed with anti-rust paint.

[0029] Working principle: Since the length direction of the friction strip 105 on the front of the cantilever 1 is opposed to the color direction of the cantilever 1, the friction strip 105 mainly increases the friction when turning the window handle. The silicone pad 5 with friction groove 501 has a high coefficient of contact friction with the skin, so it can effectively increase the contact friction regardless of the direction of turning the cantilever 1 or along the extension direction of the cantilever 1, thereby reducing slippage. The curved hook 2 is located at the farthest end of the rotation axis of the cantilever 1, and blocks the four fingers placed behind the cantilever 1 by direct contact, thereby achieving the most effective anti-slip effect.

[0030] In fact, the end of hook 2 is very close to the window frame. When the operator needs to hold the window handle, he / she needs to spread his / her four fingers so that hook 2 can pass between the handle 3 and the back of the cantilever 1 in order to hold the cantilever 1 and turn it. When the window handle needs to be released, he / she also needs to spread his / her four fingers to disengage from the back of the cantilever 1.

[0031] In actual use, simply hooking the hook 2 at the end of the handle with one finger can close the window and door, and at the same time rotate the cantilever 1 to achieve a smooth locking action.
