[0044] It should be further understood that the term “and / or” used in the present specification and the appended claims refers to any combination and all possible combinations of one or more of the associated listed items, and includes these combinations.

[0045] Embodiment 1:

[0046] See also Figure 1-4 The present embodiment discloses a side-mounted handle structure including: a handle 1 respectively arranged on a door and window profile, a transmission member 2 and a rotating wheel 3 for converting the rotation of the handle 1 into the linear movement of the transmission member 2, the handle 1 including a housing 4, the rotating wheel 3 being arranged in the housing 4, the rotating wheel 3 including a rotating member 5 and a toggle member 6, one end of the rotating member 5 being connected to the handle 1, one end of the toggle member 6 being fixedly connected to the other end of the rotating member 5, and the other end of the toggle member 6 being transmission-connected to the transmission member 2.

[0047] The utility model can realize the transmission connection between the handle 1 and the transmission member 2 only by setting the rotating wheel 3, without any other additional structure, and the transmission structure is simple, so the transmission structure does not need a larger profile cavity to meet its functional requirements, so the transmission structure can be installed on extremely narrow doors and windows, and there is no need to set a receiving groove for accommodating the handle 1 component, which is easy to install.

[0048] In this embodiment, the toggle member 6 and the rotating member 5 are integrally formed, the rotating wheel 3 and the handle 1 are separately arranged, a first connecting structure 7 is arranged on the handle 1, a second connecting structure 8 is arranged at one end of the rotating wheel 3, and the handle 1 and the rotating wheel 3 are connected through the first connecting structure 7 and the second connecting structure 8.

[0049] Among them, one of the first connection structure 7 and the second connection structure 8 is a convex block, and the other is a concave block. The configuration of the convex block and the concave block makes the transmission connection between the handle 1 and the rotating wheel 3 more stable and reliable. When the handle 1 is subjected to an external force and rotates, the convex block will abut against the inner wall of the concave block, thereby driving the rotating wheel 3 to rotate accordingly. Since the matching accuracy between the convex block and the concave block is high, the stability and accuracy of the transmission can be ensured.

[0050] In this embodiment, please refer to Figure 2-6 A connecting shaft 9 is provided at the other end of the rotating wheel 3, and a sliding part 10 is provided on the transmission member 2. The connecting shaft 9 is slidably provided on the sliding part 10 in a direction perpendicular to the moving direction of the transmission member 2. Specifically, the connecting shaft is in a columnar shape, and the sliding part 10 is in a groove shape. The relative position between the rotating wheel 3 and the transmission member 2 is changed by changing the relative position of the connecting shaft 9 in the sliding part 10, so that the entire transmission structure is simpler, easier to manufacture, and more convenient to maintain.

[0051] Among them, the connecting shaft 9 and the wheel 3 can be separately set or integrated. Preferably, the connecting shaft 9 and the wheel 3 are separately set. In this way, after the connecting shaft 9 continuously slides and wears in the sliding part 10, the connecting shaft 9 can be replaced alone without replacing the entire wheel 3, and the maintenance cost is low.

[0052] In this embodiment, please refer to Figure 2 The shell 4 and the transmission member 5 are fixed to the door and window profile by two connecting members respectively, and the connecting members include: two fixing screws 11; the shell and the transmission member are fixed by independent connecting members (that is, by four fixing screws 11), and this structure is more stable and not prone to shaking or dislocation.

[0053] In this embodiment, the angle of rotation required for the handle 1 to open and close the door and window can be adjusted by adjusting the length of the toggle member 6. For example, the prior art requires a 90-degree rotation. Under the same transmission distance, the transmission distance is increased by extending the toggle rod, so that the handle 1 only needs to be rotated 45 degrees to achieve the same open or closed state.

[0054] For further information, see Figure 7 and Figure 8 , further comprising: a locking member 12, a locking portion 13 is provided on the rotating wheel 3, the locking member 12 is reciprocatably arranged in the housing 4, and the locking member 12 can be engaged with or disengaged from the locking portion 13 when reciprocating, so as to lock or release the rotating wheel 3.

[0055] In this embodiment, the locking member 12 reciprocates, and the user can easily engage or disengage the locking portion 13, thereby locking or releasing the rotating wheel 3. This design makes the operation simple and intuitive, does not require complicated tools or steps, and improves the convenience of use. At the same time, the setting of the locking member 12 can effectively prevent children from colliding with the handle and opening the handle by themselves, thereby improving the safety of doors and windows.

[0056] For details, please refer to Fig. 9 and Fig.10 The locking member 12 includes: a moving block 14 and a limiting block 15 connected to the moving block 14, a moving groove 16 and a limiting groove 17 connected to the moving groove 16 are arranged in the shell 4, the moving block 14 is slidably arranged in the moving groove 16, one end of the limiting block 15 is slidably arranged in the limiting groove 17, and the other end of the limiting block 15 extends to the outside of the shell 4, and the reciprocating movement of the other end of the limiting block 15 can drive the moving block 14 to move reciprocally, and at the same time can drive one end of the limiting block 15 to be stuck in or out of the locking portion 13.

[0057] Among them, the other end of the limit block 15 extends outside the shell 4 to facilitate the user to better move the locking piece 12. In order to prevent the user from slipping when moving the locking piece 12, anti-slip texture or anti-slip rubber can be set on the other end of the limit block 15. The setting of the moving block 14 can, on the one hand, guide the movement of the limit block 15 to prevent the limit block 15 from tilting during the sliding process and causing jamming. On the other hand, it can also effectively fix the limit block 15 in the shell 4 to prevent the limit block 15 from detaching from the shell 4.

[0058] Furthermore, in order to improve the connection strength between the moving block 14 and the limiting block 15 , a reinforcing structure 18 may be provided at the connection between the moving block 14 and the limiting block 15 .

[0059] In this embodiment, a plurality of locking portions 13 are provided, and the plurality of locking portions 13 are arranged on the rotating member 10 around the rotation center line of the rotating wheel 3 .

[0060] Among them, multiple locking parts 13 correspond to different locking states of doors and windows. For example, when only two locking parts 13 are provided, the two locking parts 13 can correspond to the locked and opened states of the doors and windows. When three locking parts 13 are provided, the three locking parts 13 can correspond to the locked, half-open and fully-open states of the doors and windows. When the user opens the door to the desired state, he only needs to insert the locking part 12 into the locking part 13 corresponding to the desired state to continuously maintain the state.

[0061] In this embodiment, please refer to Fig.11 The rotating member 10 is provided with a first limiting portion 19 for limiting the rotation of the rotating wheel 3 in a first direction and a second limiting portion 20 for limiting the rotation of the rotating wheel 3 in a second direction. The first limiting portion 19 and the second limiting portion 20 are both in contact with the inner wall of the shell 4 to limit the rotation of the rotating wheel 3.

[0062] Specifically, the first limiting portion 19 and the second limiting portion 20 of this embodiment are both arranged in a plane. When the rotating wheel 3 rotates clockwise (i.e., the first direction) to a certain position, the first limiting portion 19 will abut against the inner wall of the housing 4 to limit the rotating wheel 3 from continuing to rotate clockwise. When the rotating wheel 3 rotates counterclockwise (i.e., the second direction) to a certain position, the second limiting portion 20 will abut against the inner wall of the housing 4 to limit the rotating wheel 3 from continuing to rotate counterclockwise. Such a design ensures that the rotating wheel 3 can stably stay at a predetermined position during the rotation process, and avoids excessive rotation of the rotating wheel 3 due to inertia or other factors.

[0063] In this embodiment, at least one elastic positioning member 21 (such as Figure 2 As shown), the rotating member 10 is provided with a plurality of positioning portions 22 (such as Figure 4Alternatively, at least one elastic positioning member 21 is provided on the rotating member 10, and a plurality of positioning portions 22 are provided on the housing 4;

[0064] When the elastic positioning member 21 is inserted into the positioning portion 22 , the handle 1 is rotationally positioned.

[0065] The shapes and sizes of the elastic positioning member 21 and the positioning portion 22 match each other to achieve precise positioning. The elastic positioning member 21 can be in the form of a spring sheet, an elastic protrusion, an elastic member, a ball, etc., and the positioning portion 22 can be in the form of a groove, a hole, etc. When the elastic positioning member 21 is inserted into the positioning portion 22, a certain clamping force can be generated due to the elastic effect of the elastic positioning member 21, so that the handle 1 is subjected to a certain resistance when rotating, thereby achieving rotational positioning.

[0066] In addition, in order to further improve the accuracy and stability of the rotational positioning, anti-slip grooves or protrusions that cooperate with each other can be provided on the elastic positioning member 21 and the positioning portion 22 to increase the friction and bite force. At the same time, the resistance and stability of the rotational positioning can also be controlled by adjusting the elasticity of the elastic positioning member 21 and the size of the positioning portion 22.

[0067] In this embodiment, a stainless steel sheet 23 (such as Figure 2 As shown in the figure, the stainless steel sheet 23 is provided with corresponding positioning holes corresponding to the positioning portion 22. The setting of the stainless steel sheet 23 can play the same role of rotational positioning as the rotating member 10 on the one hand, and can avoid the friction loss of the elastic positioning member 21 to the rotating member 10 on the other hand, thereby improving the service life of the wheel 3.

[0068] In this embodiment, a gasket 24 (such as Figure 2 As shown in FIG. 1 , the gasket 24 is usually made of a soft and wear-resistant material and can serve as a buffer layer between the handle 1 and the housing 4. In this way, when the handle 1 contacts the housing 4 during operation, the gasket 24 can reduce the direct friction between the two and reduce wear, thereby extending the service life of the overall structure.

[0069] See also Figure 1 and Figure 2The installation process of the side-mounted handle 1 of this embodiment is as follows: first, the elastic positioning member 21 is placed into the housing 4 in sequence, and then the stainless steel sheet 23 is placed on the housing 4, and then the rotating wheel 3 is placed into the housing 4 and positioned, and then the locking member 12 is placed into the housing 4, and then the rotating wheel 3 is connected to the handle 1, and then the plastic cover 25 is buckled, and then the transmission member 2 is placed into the aluminum cover 26, and the aluminum cover 26 and the transmission member 2 are connected by the fixing screws 11, and then the buckle cover 27 is buckled on both sides of the aluminum cover 26, and then the connecting shaft 9 is connected with the toggle member 6 extending from the rotating wheel 3 by riveting, so that the handle 1 and the transmission component cooperate, thereby driving the locking point on the transmission member 2 to cooperate with the lock seat, and then achieving locking.

[0070] Embodiment 2:

[0071] See also Fig.12 and Fig.13 In this embodiment, the handle 1, the toggle member 6 and the rotating member 5 are integrally formed. The integrally formed design also enhances the overall stability of the structure and improves the service life. Since it is integrally formed, there is no need to assemble each component separately during installation, and it is only necessary to fix the overall structure on the doors and windows, which greatly simplifies the installation steps and improves the installation efficiency.

[0072] Furthermore, a connecting shaft 9 is provided at the other end of the toggle member 6 , and the connecting shaft 9 and the toggle member 6 may be integrally arranged or separately arranged.

[0073] In this embodiment, the shell 4 and the transmission member 2 are connected by a connecting member 11 that penetrates the door and window profile. The connecting member includes two fixing screws 11. The shell 4 and the transmission member 2 only require one connecting member (i.e., two fixing screws 11) to be installed and fixed. The installation process is simpler, the installation steps and the number of required parts are reduced, and the installation efficiency and economic benefits are improved.

[0074] In this embodiment, please refer to Fig.14 and Fig.15 The locking member 12 includes: a moving block 14 and a limit block 15 connected to the moving block 14; a limit groove 17 is arranged in the shell 4, the moving block 14 is movably arranged in the shell 4, and the moving block 14 is provided with a toggle portion 28 extending to the outside of the shell 4, the toggle portion 28 is a convex block, and the limit block 15 is slidably arranged in the limit groove 17. The reciprocating movement of the toggle portion 28 can drive the moving block 14 to move reciprocally, and at the same time can drive the limit block 15 to be engaged in or disengaged from the locking portion 13.

[0075] Furthermore, a guide block 29 is provided on the shell 4, and a guide groove 30 is provided on the moving block 14. The guide block 29 is slidably set in the guide groove 30. The setting of the guide block 29 and the guide groove 30 can ensure that the user can move the locking member 12 more smoothly, thereby improving the user's operating experience.

[0076] Furthermore, an elastic positioning member 21 and a positioning portion 22 are also provided between the locking member 12 and the shell 4 of this embodiment for moving and positioning the locking member 12. The specific structure is the same as the structure of the elastic positioning member 21 and the positioning portion 22 between the rotating member 5 and the shell 4, and will not be elaborated on herein.

[0077] Embodiment 3:

[0078] See also Figure 16-18 In this embodiment, a transmission groove 31 is provided at the other end of the toggle member 6 , and a connecting column 32 is provided on the transmission member 2 , and the connecting column 32 is slidably installed in the transmission groove 31 .

[0079] Compared with the structure of the connecting shaft 9 and the sliding part 10 in Example 1, the structure of this embodiment converts the abutment between the two ends of the connecting shaft 9 and the inner wall of the sliding part 10 into the abutment between the inner wall of the transmission groove 31 and the side of the connecting column 32, thereby increasing the contact area between the transmission groove 31 and the connecting column 32, reducing the acting pressure between the transmission groove 31 and the connecting column 32, and reducing the damage of the transmission force to the transmission groove 31 and the connecting column 32.

[0080] Embodiment 4:

[0081] See also Fig.19 In this embodiment, a connecting shaft 9 is provided at the other end of the toggle member 6, and a sliding portion 10 is provided on the transmission member 2. The connecting shaft 9 is slidably arranged on the sliding portion 10 perpendicular to the moving direction of the transmission member 2.

[0082] The connecting shaft 9 is cam-shaped, and the cam-shaped setting can increase the contact area between the connecting shaft 9 and the sliding part 10, thereby reducing the damage to the connecting shaft 9 and the sliding part 10 caused by the transmission force. At the same time, the cam-shaped setting can also improve the structural strength of the connecting shaft 9, thereby improving the service life of the connecting shaft 9; when the handle 1 is rotated to the open and closed positions, the two side surfaces of the connecting shaft 9 with the cam-shaped setting will abut against the inner wall of the sliding part 10, thereby playing a certain positioning role.

[0083] This embodiment also provides a door and window structure, including: the side-mounted handle structure of the above embodiment.
