Description

Technical Field

[0001] This utility model relates to the technical field of door and window hardware, and in particular to a sliding support and door / window. Background Technology

[0002] There are various types of window profiles on the market. Some outward-opening sash profiles have their hardware mounting grooves designed to be closer to the exterior, while others have them closer to the interior. For profiles with mounting grooves closer to the interior, higher requirements are placed on the sliding support hardware that enables the window sash to open outwards. Key performance indicators such as the load-bearing capacity, opening trajectory, and wind pressure resistance of the sliding support all impose more stringent standards on the structural design of the hardware components.

[0003] Currently, there are three main types of profile sliding support structures on the market suitable for installation slots near the indoor side: the first is a four-bar structure with full rotation points, the second is a cross-type five-bar structure, and the third is a forward-sliding five-bar structure. However, the first structure is insufficient in terms of wind pressure resistance; the second structure, due to trajectory limitations, is only suitable for smaller profiles with thicker fan dimensions and cannot meet the market demand for larger profiles; and the third structure, because the load-bearing components need to slide, has gaps in the assembly position, which can easily lead to sagging and large opening and closing forces when the hardware is under stress.

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

[0026] This embodiment discloses an outward-opening door and window, including a frame and a sash, with a sliding brace between the frame and the sash. The sliding brace connects the sash and the frame, ensuring that the sash has sufficient load-bearing capacity and wind pressure resistance during opening and closing.

[0027] Specifically, see Figure 1-5The sliding support includes a base plate 10, a support plate 20, a cantilever 30, and a support plate 40. The base plate 10 is used to connect to the frame of the door or window; the support plate 20 is used to connect to the sash of the door or window; the support plate 40 is connected to the support plate 20; the cantilever 30 includes a long cantilever 31, a middle cantilever 32, and a short cantilever 33. One end of the long cantilever 31 is slidably connected to the base plate 10, one end of the middle cantilever 32 and one end of the short cantilever 33 are rotatably connected to the base plate 10 respectively, and the other end of the middle cantilever 32 is connected to the short cantilever 33. The other end of 3 is rotatably connected to the support plate 40, and the other end of the long suspension 31 is rotatably connected to the support plate 20; the middle suspension 32 is provided with a first stop position 321, the short suspension 33 is provided with a second stop position 331, the long suspension 31 is provided with a third stop position 311, and the support plate 40 is provided with a fourth stop position 41. When the fan body rotates to the maximum angle, the first stop position 321 and the second stop position 331 abut against each other, and the third stop position 311 abuts against the fourth stop position 41.

[0028] Compared with the prior art, the sliding support of this solution increases the load-bearing capacity of the cantilever 30 by setting the cantilever 30 as a long cantilever 31, a middle cantilever 32, and a short cantilever 33. After the fan body is opened to the maximum angle, the mutual abutment between the first stop position 321 and the second stop position 331 can realize the positioning of the short cantilever 33 and the middle cantilever 32. The mutual abutment between the third stop position 311 and the fourth stop position 41 can realize the positioning between the long cantilever 31 and the support plate 40, thereby fixing the support plate 20, preventing the fan body from opening further, and improving the wind pressure resistance of the fan body.

[0029] Understandably, the support plate 40 is fixedly connected to the support piece 20. The support plate 40 can further achieve a mutual support structure with the long suspension 31, further restricting the fan body from opening outward, so as to improve the wind pressure resistance of the fan body when it is open.

[0030] In this embodiment, one end of the long suspension 31 is connected to the first sliding plate 12 via the first rotating shaft 11, and the base plate 10 is provided with a groove to drive the first sliding plate 12 to slide. The other end of the long suspension 31 is connected to the support plate 20 via the second rotating shaft 21. One end of the middle suspension 32 is connected to the base plate 10 via the third rotating shaft 13, and the other end of the middle suspension 32 is connected to the support plate 40 via the fourth rotating shaft 42. One end of the short suspension 33 is connected to the base plate 10 via the fifth rotating shaft 14, and the other end of the short suspension 33 is connected to the support plate 40 via the sixth rotating shaft 43. Specifically, one end of the long suspension 31 will slide during the opening and closing of the fan body to ensure stable support.

[0031] In this embodiment, the third rotating shaft 13 is located between the first rotating shaft 11 and the fifth rotating shaft 14, and the fourth rotating shaft 42 is located between the second rotating shaft 21 and the sixth rotating shaft 43. During the opening and closing of the fan, the rotation directions of the long suspension 31, the middle suspension 32, and the short suspension 33 are the same and opposite to the rotation direction of the support plate 20. Rotating the long suspension 31, the middle suspension 32, and the short suspension 33 in the same direction can provide mutual support, improve the load-bearing capacity, and optimize the opening trajectory, making the opening and closing of the fan smoother.

[0032] In this embodiment, the third rotating shaft 13 and the fifth rotating shaft 14 are located on different sides of the base plate 10. The short suspension 33 and the middle suspension 32 are on the same horizontal plane. One side of the short suspension 33 is provided with a first groove 332 to accommodate one end of the middle suspension 32; the other side of the middle suspension 32 is provided with a second groove 322 to accommodate the other end of the short suspension 33. The first abutment position 321 is located on the first groove 332 at the intersection with the second groove 322, and the second abutment position 331 is located on the second groove 322 at the intersection with the first groove 332. When the short suspension 33 and the middle suspension 32 rotate to their maximum angles, the first abutment position 321 abuts against the second abutment position 331. The first groove 332 and the second groove 322 are designed to ensure that the short suspension 33 and the middle suspension 32 do not interfere with each other in the overlapping area, and also to achieve stable abutment between the first abutment position 321 and the second abutment position 331 after rotating to a preset position, resulting in smooth operation.

[0033] In this embodiment, the long suspension 31 includes a stepped high portion 312 and a low portion 313. The high portion 312 protrudes from the low portion 313. The low portion 313 is located at one end of the long suspension 31, and the high portion 312 is located at the other end of the long suspension 31. The high portion 312 is used to avoid the short suspension 33 and the middle suspension 32. The high portion 312 is flush with the support plate 40. The third abutment position 311 is located at the end of the high portion 312, and the fourth abutment position 41 is located on the surface of the support plate 40 opposite to the high portion 312. When the long suspension 31 rotates to its maximum angle, the third abutment position 311 abuts against the fourth abutment position 41. The long suspension 31 bears the greatest gravity. By abutting the long suspension 31 and the support plate 40 through the third abutment position 311 and the fourth abutment position 41, the long suspension 31 is limited, thereby ensuring the stability of the support plate 20 on which the long suspension 31 is located and improving the wind pressure resistance of the fan body in the maximum opening angle state.

[0034] In this embodiment, the sliding support also includes a fan body positioning component 50. The fan body positioning component 50 is used to sequentially pass through the support plate 40 and the support piece 20 and abut against the bottom of the fan body profile to position the support piece 20. The fan body positioning component 50 includes a rivet shaft and a screw. The rivet shaft connects the support plate 40 and the support piece 20, and the screw passes through the rivet shaft and abuts against the bottom of the fan body profile to prevent the support piece 20 and the fan body profile from shaking and deforming under wind pressure.

[0035] In this embodiment, the sliding support also includes a frame positioning member 60, which is rotatably connected to the base plate 10. After the base plate 10 is inserted into the frame profile, the frame positioning member 60 rotates to engage with the frame profile, thereby positioning the base plate 10 within the frame. The sliding support also includes a frame fixing member. The frame positioning member 60 has a first fixing hole 61, and the base plate 10 has a second fixing hole 62. When the frame positioning member 60 rotates to engage with the frame profile, the first fixing hole 61 and the second fixing hole 62 are aligned. The frame fixing member is used to sequentially pass through the first fixing hole 61 and the second fixing hole 62 to position the frame positioning member 60.

[0036] The frame positioning component 60 is a clamping piece, and the frame fixing component is a self-tapping screw. After using a tool to rotate the clamping piece to abut the frame profile, the self-tapping screw is used to pass through the first fixing hole 61 and the second fixing hole 62 in sequence and then fixed to the frame profile. This strengthens the fixing and effectively prevents the clamping piece from failing due to not being tightened properly.

[0037] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
