Description

Technical Field

[0001] This invention belongs to the technical field of building doors and windows, and particularly relates to a transmission device and a window. Background Technology

[0002] A tilt-and-turn window refers to a window where the bottom edge of the sash can be positioned so that the top edge of the sash tilts inward to open the sash, achieving the tilt-and-turn function. Simultaneously, the frame can act as a guide rail; after the sash is pushed open, it moves parallel to the guide rail along the frame to open the sash, achieving the sliding function. In existing products, due to the limited space arrangement between the bottom edge of the sash and the bottom edge of the frame, the closing and locking devices connecting the sash and the frame, as well as the tilt-and-turn locking device, are generally located on the sides of the sash and frame. In these products, because the side portion of the sash detaches from the frame during the tilt-and-turn process, gaps exist in the locking position of the tilt-and-turn locking device, making it prone to wobbling, and the bottom seal cannot be guaranteed when the sash is locked. Summary of the Invention

[0003] The purpose of this invention is to provide a transmission device and a window that can stably tilt inwards and has good locking and sealing performance.

[0004] A first aspect of the present invention discloses a transmission device, including a hinge transmission mechanism and a locking transmission mechanism. One end of the hinge transmission mechanism is fixed at a corner between the side edge and the bottom edge of the fan body, and the other end of the hinge transmission mechanism is slidably connected to the bottom edge guide rail of the frame. The locking transmission mechanism is disposed on the bottom edge of the fan body. The locking transmission mechanism includes a translation component and a locking component. One end of the translation component is connected to the hinge transmission mechanism, and the hinge transmission mechanism applies a force to the translation component to cause the translation component to slide within the fan groove at the bottom edge of the fan body. The other end of the translation component is connected to the locking component. The locking component is provided with a locking limiting part that can extend into the bottom edge guide rail of the frame. The translation component is used to drive the locking limiting part into the bottom edge guide rail of the frame. The locking limiting part is used to lock the fan body when the fan body is closed in the frame.

[0005] Furthermore, the locking assembly includes a fixed base and a rotating component. The fixed base is fixed to the bottom edge of the fan body, and the rotating component is rotatably connected to the fixed base. The locking limiting part is disposed on the rotating component. The translation component is connected to the rotating component and applies a force to the rotating component to make it rotate, so that the locking limiting part is screwed into or out of the frame guide rail.

[0006] Furthermore, the fixed seat is disposed at the fan slot of the fan body, the translation component slides within the fan slot cavity of the fan body, the rotating component is also provided with a gear part, the translation component is provided with a toothed groove part, and the gear part meshes with the toothed groove part within the fan slot cavity.

[0007] Furthermore, the fixing base includes a fan slot engaging part, a fan body positioning part, and a rotating connecting part. The fan body positioning part is fixed outside the fan slot opening. The fan slot engaging part extends from one side of the fan body positioning part into the fan slot cavity and engages with the fan slot opening. The rotating connecting part is provided on the other side of the fan body positioning part and rotatably connects to the rotating component. The surface of the fan body positioning part is provided with a rotating groove to facilitate the rotation of the rotating component.

[0008] Furthermore, the rotating component is also provided with an inward tilting limiting part. When the inward tilting limiting part is screwed into the frame guide rail, the thickness direction of the inward tilting limiting part is parallel to the width direction of the frame guide rail, and the thickness of the inward tilting limiting part is less than the width of the frame guide rail. This is used so that when the fan body tilts inward into the frame, the inward tilting limiting part rotates within the frame guide rail, thereby limiting the bottom edge of the fan body to the frame.

[0009] Furthermore, the hinge transmission mechanism includes a hinge assembly, a load-bearing assembly, and an angle transmission assembly. The two ends of the angle transmission assembly extend from the side and bottom edge of the fan body, respectively. One end of the load-bearing assembly is fixed to the fan body, and the other end of the load-bearing assembly is rotatably connected to one end of the hinge assembly. The other end of the hinge assembly is slidably connected to the guide rail of the frame. The angle transmission assembly includes a side transmission part and a bottom transmission part. Neither the side transmission part nor the bottom transmission part interferes with the load-bearing assembly. The bottom transmission part is used to connect the translation assembly.

[0010] Furthermore, one end of the load-bearing component is fixed to the side of the fan body, and the load-bearing component has a first transmission through hole along the side of the fan body. The side transmission part passes through the first transmission through hole and is connected to the side of the fan body.

[0011] Furthermore, the side transmission part has a second transmission through hole along the side of the fan body, one end of the load-bearing component is sleeved in the second transmission through hole, and the other end of the load-bearing component is rotatably connected to one end of the hinge component.

[0012] Furthermore, one end of the load-bearing component is fixed to the bottom edge of the fan body, and the bottom edge transmission part is provided with a clearance position to facilitate the passage of the load-bearing component.

[0013] A second aspect of the present invention discloses a window, including a frame, a fan, and a transmission device as described above, wherein the two ends of the transmission device are respectively connected to the frame and the fan.

[0014] The beneficial effects of this invention are as follows:

[0015] The hinge transmission mechanism in this design provides power to the translation component of the locking transmission mechanism at the bottom edge of the fan body. The translation component drives the locking limiting part of the locking component to extend into the bottom guide rail of the frame, thereby locking the fan body. The locking limiting part cooperates with the bottom guide rail of the frame, directly utilizing the frame's built-in guide rail to achieve locking and positioning of the fan body, eliminating the need for additional locking seat structures. This simplifies the locking structure and reduces the area occupied by the locking transmission mechanism on the frame, allowing the locking transmission mechanism to be used in a more compact space. When the fan body is closed, the locking limiting part locks the bottom edge of the fan body within the frame, achieving bottom edge locking and enhancing the fan body's sealing performance.

It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

For those skilled in the art, the specific meaning of the terms in this invention can be understood according to the specific circumstances.

[0033] See Figure 1 This embodiment discloses a sliding inward tilt window. The window includes a frame 2, a panel 3, and a transmission device 1, with the two ends of the transmission device 1 connected to the frame 2 and the panel 3, respectively.

[0034] See Figure 2-8The transmission device 1 includes a hinge transmission mechanism 20 and a locking transmission mechanism 10. One end of the hinge transmission mechanism 20 is fixed at the corner between the side and bottom edge of the fan body 3, and the other end of the hinge transmission mechanism 20 is slidably connected to the bottom guide rail of the frame 2. The locking transmission mechanism 10 is located at the bottom edge of the fan body 3. The locking transmission mechanism 10 includes a translation component 11 and a locking component 12. One end of the translation component 11 is used to connect to the hinge transmission mechanism 20, and the hinge transmission mechanism 20 is used to apply force to the translation component 11 to make the translation component 11 slide. The force acting on the bottom edge of the fan body 3 in the fan groove, the other end of the translation component 11 is connected to the locking component 12; the locking component 12 is provided with a locking limiting part 1221 that can extend into the guide rail of the frame 2 and an inward limiting part 1223. The translation component 11 is used to drive the locking limiting part 1221 to extend into the bottom edge guide rail of the frame 2, locking the fan body 3 when the fan body 3 is closed in the frame 2, and the translation component 11 is used to drive the inward limiting part 1223 to extend into the bottom edge guide rail of the frame 2, limiting the bottom edge of the fan body 3 to the frame 2 when the fan body 3 is inwardly tilted in the frame 2.

[0035] The hinge transmission mechanism 20 of this solution provides power to the translation component 11 of the locking transmission mechanism at the bottom edge of the fan body 3. The translation component 11 drives the locking limiting part 1221 of the locking component 12 to extend into the bottom edge guide rail of the frame 2, thereby locking the fan body 3; or, it drives the inward limiting part 1223 to extend into the bottom edge guide rail of the frame 2, thereby limiting the inward bottom edge of the fan body 3. The locking limiting part 1221 and the inward limiting part 1223 cooperate with the bottom edge guide rail of the frame 2, directly using the guide rail provided by the frame 2 to lock and position the fan body 3, without the need to add other lock seat structures, which simplifies the locking structure and reduces the area occupied by the locking transmission mechanism 10 on the frame 2, allowing the locking transmission mechanism 10 of this solution to be used in a more compact space. When the fan body 3 is closed, the locking limit part 1221 locks the bottom edge of the fan body 3 inside the frame 2, thereby achieving bottom edge locking and enhancing the sealing performance of the fan body 3. When the fan body 3 is tilted inward into the frame 2, the tilting limit part 1223 rotates synchronously with the fan body 3. The tilting limit part 1223 will never disengage from the bottom edge guide rail of the frame 2, thus playing a role in positioning the bottom edge of the fan body 3 and preventing shaking or instability when the fan body 3 is tilted inward.

[0036] In this embodiment, the locking assembly 12 includes a fixed base 121 and a rotating member 122. The fixed base 121 is fixed to the bottom edge of the fan body 3, and the rotating member 122 is rotatably connected to the fixed base 121. A locking limiting part 1221 and an inward tilting limiting part 1223 are both disposed on the rotating member 122. A translation assembly 11 is connected to the rotating member 122 and applies a force to the rotating member 122 to rotate it, causing the locking limiting part 1221 or the inward tilting limiting part 1223 to screw into or out of the bottom edge guide rail of the frame 2. The translation assembly 11 can drive the rotating member 122 to rotate until the locking limiting part 1221 or the inward tilting limiting part 1223 screws into or out of the bottom edge guide rail of the frame 2. The locking method is simple, and the locking force is large. Stable locking and bottom edge limiting of the fan body 3 can be achieved.

[0037] In this embodiment, the fixed base 121 is disposed at the fan slot opening of the fan body 3, the translation component 11 slides within the fan slot cavity of the fan body 3, and the rotating component 122 is further provided with a gear portion 1222. The translation component 11 is provided with a toothed portion 111, and the gear portion 1222 meshes with the toothed portion 111 within the fan slot cavity. The toothed portion 111 consists of multiple toothed grooves arranged along the sliding direction of the translation component 11. By sliding the translation component 11, the gear portion 1222 continuously meshes with different toothed grooves, thereby realizing the rotation of the rotating component 122. It can be understood that by sliding the translation component 11 within the fan slot cavity, allowing the gear portion 1222 to mesh with the toothed portion 111 within the fan slot cavity, the area occupied by the locking transmission mechanism 10 can be minimized. Both ends of the translation component 11 within the fan slot cavity can be connected to a transmission bar, thereby connecting to other transmission devices 1, without affecting the transmission control of the fan body 3 by the operating handle.

[0038] In this design, the locking limit part 1221 and the inward tilting limit part 1223 are symmetrically arranged at both ends of the gear part 1222 with the gear part 1222 as the center. The translation component 11 is directly controlled by the operating handle. In the open window state, the operating handle is rotated to the horizontal position, and the toothed part 111 engages with the center position of the gear part 1222. Neither the locking limit part 1221 nor the inward tilting limit part 1223 is within the guide rail of the frame 2. In the locked state of the fan body 3, the operating handle is rotated to the downward position, and the toothed part 111 moves to engage with one end of the gear part 1222. At this time, the locking limit part 1221 rotates into the guide rail of the frame 2. In the inward tilting state of the fan body 3, the operating handle is rotated to the upward position, and the toothed part 111 moves to engage with the other end of the gear part 1222. At this time, the inward tilting limit part 1223 rotates into the guide rail of the frame 2. The symmetrical arrangement of the locking limit part 1221 and the inward tilting limit part 1223 facilitates consistent control stroke during operation of the operating handle, making operation convenient.

[0039] In this embodiment, the fixing base 121 includes a fan slot engaging part 1211, a fan body positioning part 1212, and a rotating connecting part 1213. The fan body positioning part 1212 is fixed outside the fan slot opening. The fan slot engaging part 1211 extends from one side of the fan body positioning part 1212 into the fan slot cavity and engages with the fan slot opening. The rotating connecting part 1213 is provided on the other side of the fan body positioning part 1212 and rotatably connects to the rotating member 122. The surface of the fan body positioning part 1212 is provided with a rotating groove to facilitate the rotation of the rotating member 122. It should be noted that the rotating groove is directly opened on the surface of the fan body positioning part 1212 to rotatably connect the rotating connecting member, so that most of the rotating connecting member is located inside the fan slot cavity. Only after the fan body 3 is closed onto the frame 2 will the locking limiting part 1221 or the inward limiting part 1223 be rotated out into the guide rail of the frame 2, so as to minimize the impact of the rotating connecting member on the aesthetics and opening of the fan body 3 when the fan body 3 is rotated out.

[0040] In this embodiment, the translation component 11 further includes a transmission connection portion 112. The transmission connection portion 112 is provided with a transmission bar connecting post 1121 extending towards the bottom of the fan slot cavity. The transmission bar connecting post 1121 is connected to an external transmission bar. It can be understood that the transmission bar connecting post 1121 provided on the translation component 11 is connected to the external transmission bar, and the external transmission bar is connected to the operating handle, thereby controlling the sliding of the translation component 11 within the fan slot cavity through the operating handle.

[0041] In this embodiment, when the locking limiting part 1221 or the tilting limiting part 1223 is screwed into the guide rail of the frame 2, the thickness direction of the locking limiting part 1221 or the tilting limiting part 1223 is parallel to the width direction of the guide rail of the frame 2, and the thickness of the tilting limiting part 1223 is less than the width of the guide rail of the frame 2. This is used so that when the sash 3 tilts inward into the frame 2, the tilting limiting part 1223 rotates within the guide rail of the frame 2 to limit the bottom edge of the sash 3 to the frame 2. The tilting opening distance of the sliding tilting window cannot exceed 115mm, and its tilting angle is generally very small. It is only necessary to ensure that the thickness of the tilting limiting part 1223 is slightly narrower than the width of the guide rail of the frame 2, so that the tilting limiting part 1223 can rotate within a very small range, while ensuring that the bottom edge of the sash 3 is locked when the sash 3 is closed. Optionally, the thickness of the locking limit part 1221 is greater than the thickness of the inverted limit part 1223, and the thickness of the locking limit part 1221 is less than the width of the guide rail of the frame 2. This can facilitate the insertion of the locking limit part 1221 and ensure the sealing performance of the bottom edge of the fan body 3 after the locking limit part 1221 is screwed in.

[0042] In this embodiment, the hinge transmission mechanism 20 includes a hinge assembly 21, a load-bearing assembly 22, and an angle transmission assembly 23. The two ends of the angle transmission assembly 23 extend from the side and bottom of the fan body 3, respectively. One end of the load-bearing assembly 22 is fixed to the fan body 3, and the other end of the load-bearing assembly 22 is rotatably connected to one end of the hinge assembly 21. The other end of the hinge assembly 21 is slidably connected to the guide rail of the frame 2. The angle transmission assembly 23 includes a side transmission part and a bottom transmission part. Neither the side transmission part nor the bottom transmission part interferes with the load-bearing assembly 22. The bottom transmission part is used to connect to the translation assembly 11.

[0043] The translation component 11 is driven by the angle transmission component 23, which is driven by the operating handle. The operating handle is located on the side of the fan body 3. The angle transmission component 23 needs to extend from the side of the fan body 3 to the bottom edge of the fan body 3 to achieve force transmission.

[0044] See Figure 9 In the first embodiment, one end of the load-bearing component 22 is fixed to the side of the fan body 3. The load-bearing component 22 has a first transmission through hole 221 along the side of the fan body 3. The side transmission part passes through the first transmission through hole 221 and is connected to the side of the fan body 3. It is understood that the load-bearing component 22 is used to support the weight of the window. To increase the load-bearing capacity of the load-bearing component 22, this solution places the load-bearing component 22 on the side of the fan body 3. The load-bearing component 22 and the side transmission part are relatively independent. It is only necessary to open a recessed first transmission through hole 221 near the side of the fan body 3 on the load-bearing component 22, allowing the side transmission part to pass through the first transmission through hole 221, to achieve non-interference between the load-bearing component 22 and the angle transmission component 23.

[0045] See Figure 10 In the second embodiment, the side transmission part has a second transmission through hole 231 along the side of the fan body 3. One end of the load-bearing component 22 is fitted into the second transmission through hole 231, and the other end of the load-bearing component 22 is rotatably connected to one end of the hinge component 21. In this embodiment, the angle transmission component 23 and the load-bearing component 22 share a mounting base installed on the fan body 3, and the transmission bar and the load-bearing shaft of the load-bearing component 22 pass through the mounting base respectively.

[0046] See Figure 11 In the third embodiment, one end of the load-bearing component 22 is fixed to the bottom edge of the fan body 3, and the bottom edge transmission part is provided with a clearance 232 to facilitate the passage of the load-bearing component 22. During the transmission process, the load-bearing component 22 is always within the clearance 232, so that the load-bearing component 22 and the bottom edge transmission part will not interfere with each other.

[0047] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
