[0037] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0038] like Figures 1-5 The diagram shows a schematic of an inward-folding escape window provided in this embodiment of the present invention. This inward-folding escape window can be installed on a glass curtain wall, etc., and can achieve indoor ventilation and lighting. The inward-folding escape window of this embodiment includes a window frame 10, a window sash 20, and connecting components. The window sash 20 is generally rectangular and includes a sash frame 21 and a glass panel 22, with the glass panel 22 fixed inside the sash frame 21. The window frame 10 can be U-shaped and can be fixed to the window position of the curtain wall, with its outer side fixed to the curtain wall. The window sash 20 is installed in the inner opening 11 of the window frame 10 through the connecting components. The structure and materials of the window frame 10 and the window sash 20 can all adopt conventional solutions in the art, and will not be described in detail here.
[0039] The aforementioned window frame 10 includes two first side plates 12 with flat surfaces, and the two first side plates 12 are respectively located on both sides of the inner opening 11, that is, the two first side plates 12 are parallel and adjacent to the inner opening 11 respectively; correspondingly, the sash frame 21 includes two second side plates 211 with flat surfaces, the two second side plates 211 are arranged back to back, that is, the two second side plates 211 are parallel and are respectively located on the two outer edges of the sash frame 21. The connecting assembly includes a slide groove 311, a quick-release assembly, a connecting rod 41 and a slider 42, and each first side plate 12 has a slide groove 311 and a quick-release assembly, and each second side plate 211 has a connecting rod 41 and a slider 42.
[0040] The aforementioned groove 311 runs along the length of the first side plate 12 (e.g.) Figure 3 The slide groove 311 is positioned in the direction indicated by the middle arrow X and extends from the first end of the first side plate 12 to the end of the first side plate 12 (as those skilled in the art will understand, the first end and the end of the first side plate 12 are located at opposite ends of the length direction of the first side plate 12), and the slide groove 311 has an opening toward the end of the first side plate 12. That is, the slide groove 311 occupies a portion of the length direction of the first side plate 12 and has an opening between the first end and the end of the first side plate 12.
[0041] The quick-release assembly includes a fixed shaft 321 and a retaining ring 322. The fixed shaft 321 is perpendicular to the first side plate 12 and located between the opening of the slide groove 311 and the end of the first side plate 12. The retaining ring 322 is fitted onto the fixed shaft 321, and the radial dimension of the fixed shaft 321 is smaller than the inner diameter of the retaining ring 322 in its natural state (i.e., without external force). Those skilled in the art will understand that the fixed shaft 321 is cylindrical and protrudes from the surface of the first side plate 12; the retaining ring 322 is generally annular, and its radial dimension can change under stress. In practical applications, the fixed shaft 321 can be made of rivets, and the retaining ring 322 can be made of a notched metal ring.
[0042] The slider 42 is rotatably connected to the end of the second side plate 211, that is, the slider 42 is fitted to one end of the outer side of the fan frame 21 and can rotate relative to the fan frame. For example, the slider 42 can be movably installed onto the surface of the second side plate 211 by means of rivets or the like (after installation, the slider 42 protrudes from the surface of the second side plate 211). Furthermore, the size of the slider 42 is adapted to the size of the slide groove 311, that is, the slider 42 can be embedded in the slide groove 311 and can slide along the slide groove 311.
[0043] The connecting rod 41 is elongated, with its first end hinged between the first and second ends of the second side plate 211. For example, the first end of the connecting rod 41 can be hinged to the middle of the second side plate 211 via a rivet or similar means. Furthermore, the end of the connecting rod 41 has a mounting hole 411. The radial dimension of the mounting hole 411 is larger than the radial dimension of the fixed shaft 321 but smaller than the outer diameter of the retaining spring 322 in its natural state. The outer diameter of the retaining spring 322 in its maximum compressed state is smaller than the radial dimension of the mounting hole 411. That is, the fixed shaft 321 can be inserted into the mounting hole 411, and the retaining spring 322 fitted onto the fixed shaft 321 can also pass through the mounting hole 411 in its maximum compressed state, while the retaining spring 322 cannot pass through the mounting hole 411 in its natural state.
[0044] When the window sash 20 is assembled to the window frame 10 via the connecting assembly, the sliders 42 on the two second side plates 211 are respectively embedded in the grooves 311 of the two first side plates 12, and the ends of the two connecting rods 41 are rotatably connected to the fixed shafts 321 of the two first side plates 12 through the mounting holes 411 and limited by the retaining rings 322 (to prevent them from coming out of the fixed shafts 321). In particular, the grooves 311 can be C-shaped grooves, and correspondingly, the sliders 42 include two wings that are respectively embedded in the two sides of the C-shaped grooves, thereby preventing the sliders 42 from coming out of the grooves 311 (except for the part of the grooves 311 opening).
[0045] The aforementioned inward-folding escape window uses a fixed shaft 321 and a retaining spring 322 to lock the end of the connecting rod 41 hinged to the sash frame 21. This locks the slider 42, also hinged to the sash frame 21, into the groove 311 on the window frame 10, with its opening facing the end of the first side plate 12. Under normal use, the window sash 20 can be opened and closed for ventilation by the two ends of the connecting rod 41 rotating relative to the sash frame 21, and the slider 42 sliding within the groove 311 while simultaneously rotating relative to the sash frame 21. In an emergency, by pushing the end of the connecting rod 41 towards the inner opening 11 of the window frame 10, the retaining spring 322 is compressed and passes through the mounting hole 411 at the end of the connecting rod, allowing the end of the connecting rod 41 to be removed from the fixed shaft 321. Figure 7 As shown, then slide the slider 42 along the groove 311 to its opening, as shown. Figure 9 As shown, the window sash 20 can then be removed from the window frame 10 to enable escape. Once safe, the two sliders 42 on the window sash 20 can be inserted into the grooves 311 through the openings, as shown. Figure 8 As shown, the mounting holes 411 of the two connecting rods 41 are then respectively fitted onto the two fixed shafts 321 of the window frame 10, and the mounting holes 411 are pushed past the retaining rings 322 by applying force to compress the retaining rings 322. Figure 6 As shown, the window sash 20 can be reinstalled onto the window frame 10 for reuse, saving resources.
[0046] In one embodiment of this utility model, the two first side plates 12 are respectively located on the two vertical sides of the window frame 10, and correspondingly, the two second side plates 211 are respectively located on the two vertical sides of the sash frame 21. That is, the window sash 20 rotates along the horizontal axis when opened.
[0047] Specifically, the first end of the first side plate 12 is located at the bottom of the first side plate 12, and the first end of the second side plate 211 is located at the bottom of the second side plate 211. In this way, the danger of the window sash 20 directly detaching from the opening of the slide groove 311 under the action of gravity can be avoided after the end of the connecting rod 41 separates from the fixed shaft 321.
[0048] In one embodiment of this utility model, the length of the slide groove 311 is greater than or equal to half the length of the first side plate 12, and the distance between the fixed shaft 321 and the end of the first side plate 12 is less than the distance between the fixed shaft 321 and the opening of the slide groove 311. In this way, the opening angle of the window sash 20 can be relatively large.
[0049] In one embodiment of this utility model, the connecting assembly further includes limiting posts 511 located on each of the second side plates 211. The limiting posts 511 are located between the slider 42 and the first end of the connecting rod 41, and when the connecting rod 41 abuts against the limiting posts 511, the slider 42 remains in the sliding groove 311. Those skilled in the art will understand that, in order to limit the rotation of the connecting rod 41, the limiting posts 511 need to protrude from the surface of the second side plate 211. Through the limiting posts 511, the rotation of the connecting rod 41 can be limited, thereby limiting the opening angle of the window sash 20.
[0050] Meanwhile, since the slider 42 remains in the groove 311 when the connecting rod 41 abuts against the limiting post 511, it can be ensured that the slider 42 cannot come out of the groove 311 when the end of the connecting rod 41 has not come out of the fixed shaft 321. That is, the limiting post 511 can also prevent the window sash 20 from falling off the window frame 10 during the normal opening and closing of the window sash 20.
[0051] In one embodiment of this utility model, the fixed shaft 321 has a circumferential groove 3211. The width of the circumferential groove 3211 is adapted to the thickness of the retaining spring 322, and the radial dimension of the bottom wall of the circumferential groove 3211 is smaller than the difference between the radial dimension of the mounting hole 411 and the radial dimension of the retaining spring 322. With the above structure, on the one hand, it can be ensured that the retaining spring 322 slides along the axial direction of the fixed shaft 321 and disengages from the fixed shaft 321. On the other hand, it can also be ensured that the retaining spring 322 is deformed under pressure, so that the connecting rod 41 can move to the inner side of the retaining spring 322 (i.e., between the retaining spring 322 and the first side plate 12) by compressing the retaining spring 322.
[0052] Specifically, the cross-section of the aforementioned retaining ring 322 is circular, and correspondingly, the mounting hole 411 at the end of the connecting rod 41 has chamfers on both surfaces of the connecting rod 41. This structure allows the retaining ring 322 to be compressed through the chamfers when the connecting rod 41 is under stress, thereby facilitating the installation and removal of the connecting rod 41.
[0053] In one embodiment of this utility model, the sum of the distance between the first end of the connecting rod 41 and the slider 42 and the length of the connecting rod 41 is adapted to the distance between the fixed shaft 321 and the first end of the first side plate 12. In this way, the window sash 20 can be completely closed.
[0054] In one embodiment of this utility model, the connecting assembly includes a first fixing strip 31, which is fixed to the first side plate 12 along its length (e.g., by screws), and both the sliding groove 311 and the fixing shaft 321 are located on the first fixing strip 31. Specifically, the sliding groove 311 can be formed by bending the two sides of the width direction of the first fixing strip 31. This structure improves the integration of the connecting assembly and facilitates its installation. Of course, in practical applications, the sliding groove 311 and the fixing shaft 321 can also be separate structures, but the installation process is relatively complex.
[0055] In one embodiment of this utility model, the connecting assembly further includes a second fixing strip 51, which is fixed to the second side plate 211 along its length (e.g., by screws). The first end of the connecting rod 41 is hinged to the second fixing strip 51, and the slider 42 is rotatably connected to the second fixing strip 51. This structure improves the integration of the connecting assembly and facilitates its installation. For example, the connecting rod 41 and the slider 42 can be connected to the second fixing strip 51 first, and then the second fixing strip 51 can be fixed to the second side plate 211. Of course, in practical applications, the connecting rod 41 and the slider 42 can also be installed separately on the second side plate 211, but the installation process is relatively complex.
[0056] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
