Description

Technical Field

[0001] This utility model relates to the field of door and window hardware technology, specifically a door and window handle. Background Technology

[0002] As a key component of building doors and windows, door and window handles have the core function of helping users easily open and close doors and windows, ensuring convenience and comfort in daily use. In modern designs, handles are often integrated with locking systems, using transmission components to drive the latch or latch to extend and retract, thus enabling the functions of unlocking and locking.

[0003] In existing technologies, many traditional door and window handles lack an effective automatic reset mechanism for their transmission components after the opening and closing action is completed. Specifically, after a user completes an opening and closing operation, the transmission components usually remain in the final position and do not automatically return to the initial state. This design requires the user to manually adjust the position of the transmission components before the next operation to ensure that the handle can work smoothly. This manual reset requirement not only increases the complexity of operation but also significantly reduces the ease of use. Utility Model Content

Detailed Implementation

[0039] The overall concept of the technical solution provided by this utility model is as follows:

[0040] Please see Figures 1 to 4 Door and window handles include:

[0041] Handle body 100; Handle body 100 is the component that the user directly contacts and operates, through which the user applies force to control the opening and closing of doors and windows. Handle body 100 is the base 900 of the entire door and window handle, providing support and fixation for other components. Handle body 100 can be made of high-strength materials, such as stainless steel, aluminum alloy, or engineering plastics, to ensure long-term durability and wear resistance.

[0042] The driving component 200 is movably connected to the handle body 100. The main function of the driving component 200 is to transmit the force applied by the user to the transmission component 300, thereby enabling power transmission between the transmission component 300 and the external door / window actuator, achieving the unlocking or unlocking operation of the door / window. Depending on user needs and application scenarios, the driving component 200 can be designed in different structural forms, such as a button structure (typically a raised component that the user applies force by pressing) or a wrench structure (typically a lever-like component that the user applies force by pulling). The driving component 200 and the handle body 100 are movably connected, allowing the driving component 200 to move freely within a certain range, such as relative rotation or relative sliding between them. The movement mode of the drive component 200 needs to be designed according to its structural form and application scenario. For example, the movement trajectory of a button structure is usually a sliding connection, while the movement trajectory of a wrench structure is usually a rotary connection.

[0043] The transmission component 300 is slidably connected to the handle body 100. The driving component 200 is meshed with the transmission component 300 and is used to drive the transmission component 300 to slide. The transmission component 300 is mainly used to convert the force transmitted from the driving component 200 into the movement of the external door and window actuator, thereby realizing the unlocking or unlocking operation. It can be understood that the transmission component 300 may be provided with a square shaft connected to the external door and window actuator, and the movement of the square shaft directly drives the door and window actuator to work.

[0044] The elastic element 400 connects the transmission element 300 and the handle body 100. The elastic element 400 provides the transmission element 300 with an elastic force to return to its initial position. The elastic element 400 primarily provides this force through its own elastic deformation, ensuring that the transmission element 300 automatically rebounds after operation, thus automatically returning to its initial state after each operation without requiring manual adjustment by the user.

[0045] Furthermore, the automatic reset function of the transmission components is achieved through the coordinated action of the driving component 200, the transmission component 300, and the elastic component 400. When the user operates the handle, the driving component 200 is driven, which in turn drives the transmission component 300. The transmission component 300 is connected to the door / window's actuator, thereby driving the actuator to work and complete the unlocking or unlocking operation. After each operation, the elastic component 400 automatically drives the transmission component 300 to rebound, returning it to its initial state. When performing the next operation, the user does not need to adjust the handle position separately; they only need to focus on the opening and closing action. This design effectively solves the defect of manual reset of transmission components in existing technologies, significantly improving ease of use.

[0046] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0047] Please see Figures 1 to 4 and Figure 6 Door and window handles also include:

[0048] The connector 500 has a connecting hole 110 on the handle body 100. One end of the connector 500 is used to fix it to the door and window profile 600, and the other end is used to insert into the connecting hole 110. The part of the connector 500 located in the connecting hole 110 has a radial groove 510. The handle body 100 has a through hole 120 communicating with the connecting hole 110. The axial direction of the through hole 120 is aligned with the opening direction of the radial groove 510. One end of the connector 500 is used to fix it to the door and window profile 600, which can be achieved by screws, rivets or other fastening methods.

[0049] A first fastener 700 passes through the through hole 120 and extends into the radial groove 510. The engagement of the first fastener 700 with the radial groove 510 locks the connector 500 into the connecting hole 110. The first fastener 700 can be a screw, and the through hole 120 can be designed as a threaded hole. By screwing the screw into the threaded hole, and then through the threaded hole into the radial groove 510, the engagement of the screw with the radial groove 510 locks the connector 500 into the connecting hole 110.

[0050] Please see Figure 1 and Figure 3 The connector 500 includes:

[0051] Rivet nut 520 is used to fix the door and window profile 600. Understandably, mounting holes can be pre-machined on the door and window profile 600 for installing rivet nut 520. The rivet nut 520, through the pulling force of the rivet tool, causes its deformed area to form a protrusion or flange on the other side of the door and window profile 600, thereby achieving a firm connection.

[0052] A fixing seat 530 is connected to a rivet nut 520 via a second fastener 540, and the fixing seat 530 has a radial groove 510 on its side wall. Specifically, the main body of the rivet nut 520 is typically cylindrical with internal threads for engaging with the second fastener 540 (e.g., a screw). The radial groove 510 on the side wall of the fixing seat 530 engages with a first fastener 700 (e.g., a screw) to achieve a locking function. The second fastener 540 passes through a mounting hole on the fixing seat 530 and then engages with the threaded hole of the rivet nut 520. By tightening the second fastener 540, a secure connection between the fixing seat 530 and the rivet nut 520 is achieved.

[0053] Please see Figure 1 and Figure 2 The driving component 200 is slidably connected to the handle body 100. The driving component 200 is provided with a first rack portion 210, and the transmission component 300 is provided with a second rack portion 310. The first rack portion 210 and the second rack portion 310 are simultaneously meshed with the transmission gear 800. The sliding of the driving component 200 is transmitted through the meshing of the transmission gear 800, and the transmission component 300 is driven to slide in opposite directions. Specifically, the drive component 200 and the handle body 100 are slidably connected, allowing the drive component 200 to slide freely on the handle body 100. For example, the drive component 200 can slide within a groove designed on the handle body 100. The drive component 200 has a first rack portion 210, which is a linear rack structure, for meshing with the transmission gear 800. The first rack portion 210 converts the linear motion of the drive component 200 into the rotational motion of the transmission gear 800. The transmission component 300 has a second rack portion 310, also a linear rack structure, for meshing with the transmission gear 800. The second rack portion 310 converts the linear motion of the drive component 200 into the rotational motion of the transmission gear 800. The rotational motion is converted into the sliding motion of the transmission component 300. When the user presses the drive component 200, the drive component 200 slides on the handle body 100. The linear motion of the drive component 200 is transmitted to the transmission gear 800 through the first rack portion 210. After receiving the force from the first rack portion 210, the transmission gear 800 begins to rotate. The rotational motion of the transmission gear 800 is transmitted to the transmission component 300 through the second rack portion 310. After receiving the rotational motion of the transmission gear 800, the transmission component 300 begins to slide in the opposite direction. The sliding motion of the transmission component 300 is transmitted to the door and window actuator through the connection point, thereby realizing the unlocking or unlocking operation of the door and window.

[0054] Please see Figure 1 Door and window handles also include:

[0055] The first shaft 810 has a first shaft center hole 820 at the position of the rotation axis of the transmission gear 800, and the handle body 100 has a first bearing hole 130 at the position corresponding to the first shaft center hole 820. The first shaft 810 passes through the first shaft center hole 820 and the first bearing hole 130. Specifically, the main function of the first shaft 810 is to support the rotation axis of the transmission gear 800, ensuring that the transmission gear 800 can rotate freely relative to the handle body 100. Bearings or bushings can be installed in the first shaft center hole 820 or the first bearing hole 130 to reduce the friction between the first shaft 810 and the hole wall.

[0056] Please see Figure 3 and Figure 4 The driving member 200 is rotatably connected to the handle body 100. The outer peripheral surface of the driving member 200 is provided with a third rack portion 220, and the transmission member 300 is provided with a fourth rack portion 320 for direct meshing with the third rack portion 220. The rotational motion of the driving member 200 is converted into the linear sliding motion of the transmission member 300 through the meshing of the third rack portion 220 and the fourth rack portion 320. The driving component 200 and the transmission component 300 achieve mutual conversion between rotational motion and linear sliding through rack and pinion engagement. Specifically, the driving component 200 can be rotatably connected to the handle body 100 via mechanical connections such as bearings, pivots, or rotating shafts. For example, the driving component 200 can be mounted on the handle body 100 via a rotating shaft, allowing it to rotate around the shaft. The driving component 200 transmits the rotational force applied by the user to the transmission component 300 through rotation. The third rack portion 220 on the outer peripheral surface of the driving component 200 is typically a ring rack structure, used for direct engagement with the fourth rack portion 320 of the transmission component 300. The third rack portion 220 converts the rotational motion of the driving component 200 into the linear motion of the transmission component 300. The transmission component 300 is provided with the fourth rack portion 320... It is usually a linear rack and pinion structure, used to directly mesh with the third rack portion 220 of the drive member 200. The fourth rack portion 320 converts the rotational motion of the drive member 200 into the linear sliding motion of the transmission member 300. The user applies a rotational force to the drive member 200, such as by turning the drive member 200. The drive member 200 rotates on the handle body 100. The rotational motion of the drive member 200 is transmitted to the fourth rack portion 320 through the third rack portion 220. The third rack portion 220 and the fourth rack portion 320 mesh directly. The rotational motion of the third rack portion 220 is converted into the linear motion of the fourth rack portion 320. The linear motion of the fourth rack portion 320 drives the transmission member 300 to slide in a linear direction. The sliding motion of the transmission member 300 is transmitted to the door and window actuator through the connection point, thereby realizing the unlocking or unlocking operation of the door and window.

[0057] Please see Figure 3 Door and window handles also include:

[0058] The second shaft 230 has a second shaft center hole 240 at the position of the rotation axis of the drive member 200, and a second bearing seat hole 140 is provided on the handle body 100 at the position corresponding to the second shaft center hole 240. The second shaft 230 passes through the second shaft center hole 240 and the second bearing seat hole 140. The main function of the second shaft 230 is to support the rotation axis of the drive member 200, ensuring that the drive member 200 can rotate freely relative to the handle body 100. Bearings or bushings are usually installed in the second shaft center hole 240 or the second bearing seat hole 140 to reduce the friction between the second shaft 230 and the hole wall.

[0059] Please see Figure 1 , Figure 3 and Figure 6 Door and window handles also include:

[0060] The base 900 is connected inside the handle body 100. The bottom of the base 900 is provided with a through linear guide groove 910. The main function of the base 900 is to provide support and positioning for the various components on the handle body 100. The through linear guide groove 910 at the bottom of the base 900 is used to guide the linear movement of the transmission component 300 and ensure that the transmission component 300 moves accurately along a predetermined trajectory during the movement. The base 900 can be firmly installed inside the handle body 100 by screws, connecting shafts or other fixing methods.

[0061] The transmission component 300 has symmetrical guide bosses 330 on both sides. The transmission component 300 passes through the linear guide groove 910, and one side wall of the guide boss 330 abuts against the side of the linear guide groove 910. The cooperation between the guide boss 330 and the side of the linear guide groove 910 further ensures the accuracy of the movement trajectory of the transmission component 300 and prevents deviation and jamming.

[0062] For further details, please refer to Figure 6 The elastic element 400 is a compression spring 410; through the elastic deformation of the compression spring 410, the transmission element 300 can automatically return to its initial state after each operation, without the need for manual adjustment by the user.

[0063] The base 900 is provided with a spring receiving cavity 920 extending along the sliding direction of the transmission member 300, and the compression spring 410 is provided in the spring receiving cavity 920;

[0064] The guide boss 330 has a columnar protrusion 331 on its side, parallel to the sliding direction of the transmission component 300. The first end of the compression spring 410 is sleeved and fixed to the columnar protrusion 331, and the second end of the compression spring 410 elastically abuts against the side wall of the spring receiving cavity 920. When the user operates the transmission component 300, the compression spring 410 is compressed and stores elastic potential energy. After the operation is completed, the compression spring 410 releases the stored elastic potential energy and pushes the transmission component 300 back to its initial position.

[0065] Please see Figures 1 to 4 and Figure 6 Door and window handles also include:

[0066] The cover 930 covers the opening of the spring receiving cavity 920 of the base 900 and is detachably connected to the base 900 via a third fastener 931. The main function of the cover 930 is to cover and protect the spring receiving cavity 920 on the base 900, preventing external dust, impurities, etc. from entering the cavity and affecting the normal operation of the compression spring 410 and other internal components. The cover 930 is detachably connected to the base 900 via the third fastener 931 (such as a screw or clip), which allows the cover 930 to be opened when needed to inspect, maintain, or replace the components (such as the compression spring 410) inside the spring receiving cavity 920.
