Abstract
Description
Technical Field
[0001] The present application relates to the technical field of door and window hardware products, and more specifically, to an inward opening and tilting hinge. Background Art
[0002] Doors and windows are opening devices used by people in daily life buildings to introduce light and air. Existing windows generally include window frames installed on buildings and window sashes installed on the window frames. Transparent glass is installed in the window sashes, and the window sashes are hinged to the window frames by means of hinges. With the development of the construction field and the improvement of human living standards, customers' demands for the diversity and aesthetics of door and window hinges are also increasing. Hinges that can realize inward opening and inward tilting of windows have become a more popular style. Through the inward opening and inward tilting hinges, the window sash can not only rotate around the vertical axis to achieve horizontal opening, but also rotate around the horizontal axis relative to the bottom of the window frame to open the smaller space on the upper part and achieve inward tilting. Inward opening and inward tilting windows are not only safer, but also have better ventilation and rain protection effects.
[0003] Due to the limitation of the relative sizes of the latch, the angle turner and the latch lock block, in order to switch between the latch solution and the multilateral multi-point lock angle turner solution for most of the inward-opening and inward-tilting hinge products on the market, it is necessary to order different types of products. Once the product is ordered and installed, it is very troublesome to switch the solution. It is often necessary to first remove the latch from the transmission rod, replace and install the limit link, remove the latch lock block, and then connect the angle turner to the limit link before switching to the angle turner solution. This brings great inconvenience to customers' installation and use. Utility Model Content

[0045] In order to make the purpose, technical solutions and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not intended to limit the present application. In addition, the embodiments in the present application and the features in the embodiments may be combined with each other in the absence of conflict.
[0046] Figure 1 FIG. 1 shows a schematic diagram of the overall structure of an inward opening and tilting hinge 100 according to an embodiment of the present application. Figure 1 As shown, the inward-opening and inward-tilting hinge 100 is mainly composed of a frame connecting assembly 10, a sash connecting assembly 20 and a connecting rod assembly 30. The frame connecting assembly 10 is used to connect to the window frame profile, the sash connecting assembly 20 is used to connect to the window sash profile, and the connecting rod assembly 30 is connected between the frame connecting assembly 10 and the sash connecting assembly 20, and is used to drive the sash connecting assembly 20 to move relative to the frame connecting assembly, thereby realizing the inward-opening and inward-tilting function of the window sash relative to the window frame.
[0047] See Figure 1 As shown, the frame connection assembly 10 is mainly connected into an L shape by a first mounting plate 11 and a second mounting plate 12. The first mounting plate 11 is provided with a first fixing structure 111 for fixing and mounting with the top profile of the window frame, and the second mounting plate 12 is provided with a second fixing structure 121 for fixing and mounting with the side profile of the window frame, so as to fix the frame connection assembly 10 to the window frame as a whole. In a specific embodiment, the first fixing structure 111 and the second fixing structure 121 can be realized by existing technical means such as screws and fixing washers. The first mounting plate 11 is provided with a first slide groove 112 extending along the length extension direction thereof at one end close to the second mounting plate 12, and an adjustment lock block 13 is provided on the inner side of the second mounting plate 12 relatively away from the window frame. For further information, see Figure 5 As shown, the adjusting lock block 13 is installed and fixed on the inner side of the second mounting plate 12 through a first eccentric adjusting rivet 131 , and a locking hole 132 is formed at the upper end of the adjusting lock block 13 .
[0048] See also Figure 1As shown, the window connection assembly 20 is mainly composed of a connection shell 21, a transmission rod 22, a limit connecting rod 23 and a limit latch 24. The connection shell 21 is fixedly installed on the top profile of the window sash, and a second slide groove 211 extending along the length extension direction thereof is provided on the upper part of the connection shell 21. The transmission rod 22 is penetrated through the connection shell 21 along the length extension direction of the connection shell 21, and forms a sliding fit with the connection shell 21. A transmission connection structure 221 (such as a rivet, etc.) is provided at one end of the transmission rod 22, which is used to be linked with an operating component such as a handle. The other end of the transmission rod 22 is fixedly connected to one end of the limit connecting rod 23 by an eccentric adjustment rivet 222, and the other end of the limit connecting rod 23 away from the transmission rod 22 is detachably plugged with the limit latch 24. By driving the transmission rod 23 to slide along the length direction relative to the connection shell 21 through the operating component, the limit connecting rod 23 can be driven to move together with the limit latch 24.
[0049] See also Figure 1 As shown, the connecting rod assembly 30 includes a main rod 31, a limiting rod 32, a rocking rod 33 and a secondary rod 34. One end of the main rod 31 is hinged to one end of the rocking rod 33 through a first rivet 311, and the other end of the main rod 31 is riveted to the second slide groove 211 on the connecting housing 21 through a second rivet 312. One end of the limiting rod 32 is riveted to the first slide groove 112 on the first mounting plate 11 through a third rivet 321, and the other end of the limiting rod 32 is riveted to the third slide groove 313 opened along the length extension direction of the main rod 31 through a fourth rivet 322. The other end of the rocking rod 33 is hinged to one end of the first mounting plate 11 relatively away from the first slide groove 112 through a fifth rivet 331, and the middle part of the rocking rod 33 is also hinged to the middle part of the limiting rod 32 through a sixth rivet 332. One end of the auxiliary rod 34 is connected to the end of the housing 21 that is closer to the limiting connecting rod 23 relative to the second sliding groove 211 through the seventh rivet 341, and the other end of the auxiliary rod 34 is hinged to the main rod 31 through the eighth rivet 342.
[0050] Thus, when the window sash is in the locked state, the main rod 31, the limit rod 32, the rocker 33, the auxiliary rod 34, and the connecting shell 21 are all overlapped with the first mounting plate 11, and the transmission rod 22 slides relative to the connecting shell 21 until the pin head 241 of the limit pin 24 is inserted into the lock hole 132 of the adjusting lock block 13 (see Figure 5When the transmission rod 22 slides relative to the connection housing 21 until the pin head 241 of the limit pin 24 escapes from the lock hole 132 of the adjustment lock block 13 but the rocker slider mechanism composed of the main rod 31, the auxiliary rod 34 and the connection housing 21 does not move, the main rod 31, the auxiliary rod 34, the connection housing 21 and the transmission rod 22 rotate relative to the limit rod 32, so that the rocker 33 can rotate relative to the first mounting plate 11, and the limit rod 32 can rotate relative to the first mounting plate 11 and slide along the first slide groove 112, thereby switching the hinge 100 to the horizontal opening state to realize the horizontal opening of the window sash. When the transmission rod 22 slides relative to the connecting shell 21 until the pin head 241 of the limiting pin 24 disengages from the lock hole 132 of the adjusting lock block 13 and the rocker slider mechanism composed of the main rod 31, the auxiliary rod 34 and the connecting shell 21 is also released from the restriction, the window sash is pulled inward, the main rod 31 can rotate around the connecting shell 21 and slide along the second slide groove 211, the auxiliary rod 34 rotates relative to the connecting shell 21 to limit the rotation angle of the main rod 31, the rocker 33 rotates relative to the main rod 31 and the first mounting plate 11, and the limiting rod 32 rotates and slides relative to the first mounting plate 11 and the main rod 31, thereby switching the hinge 100 to the inward tilt state to realize the inward tilt function of the window sash. When the hinge 100 is tilted inward to the maximum angle, the main rod 31 rotates around the connecting shell 21 through the second rivet 312 and slides along the second slide groove 211 to the end of the stroke. The second rivet 312 is inserted into the inward limit block 212 provided on the connecting shell 21 to ensure that the window sash is not easily closed or shaken when subjected to wind pressure.
[0051] In order to enable the inward opening and tilting hinge 100 to quickly switch between the latch solution and the corner turner solution, the present application designs the limit connecting rod 23 and the limit latch 24 to be split. Figure 2 As shown, the other end of the limiting link 23 relatively far from the transmission rod 22 is provided with a first slot 231 for the limiting pin 24 to be inserted and fixed in a detachable manner. The end of the limiting link 23 relatively close to the transmission rod 22 is provided with a second slot 232 for the transmission rod 22 to be inserted and fixedly connected to the transmission rod 22 through the second eccentric adjustment rivet 222.
[0052] See Figure 2 and Figure 3 As shown, a guiding slope 235 is formed at the entrance of the first slot 231 of the limiting link 23, and a clamping hole 233 penetrating to the upper surface of the limiting link 23 is formed behind the guiding slope 235, and a clamping groove 234 connected to the clamping hole 233 is formed on the upper surface of the limiting link 23 behind the clamping hole 233. The limiting link 23 also has first flanges 236 retracted a distance relative to the entrance of the first slot 231 formed on both sides, and the front end surface of the first flange 236 forms a first limiting surface 237. Correspondingly, see Figure 2 and Figure 4 As shown, the limit pin 24 forms a pin head 241 at the front end away from the limit link 23, which is used to cooperate with the lock hole 132 of the adjustment lock block 13, and the limit pin 24 forms a plug connector 242 at the rear end opposite to the limit link 23, which cooperates with the first slot 231 of the limit link 23. A protrusion 243 is convexly provided on the upper surface of the plug connector 242, and a clamping block 244 extends from the rear end of the protrusion 243. Second flanges 245 that are retracted a distance relative to the plug connector 242 are also formed on both sides of the limit pin 24, and the rear end surface of the second flange 245 forms a second limit surface 246. When the plug connector 242 of the limiting plug 24 is inserted into the first slot 231 of the limiting link 23 along the guiding inclined surface 235, so that the protrusion 243 is embedded in the clamping hole 233 and the clamping block 244 is clamped into the clamping slot 234 through elastic deformation, the second limiting surfaces 246 of the second flanges 245 on both sides of the limiting plug 24 abut against the first limiting surfaces 237 of the first flanges 236 on both sides of the limiting link 23, and the limiting plug 24 is inserted in place and fixed to the limiting link 23, and can slide relative to the connecting housing 21 together with the limiting link 23 under the drive of the transmission rod 22 (see Figure 1 After the protrusion 243 embedded in the clamping hole 233 is pressed downward to make the clamping block 244 come out of the clamping groove 234 through elastic deformation, the plug connector 242 of the limit pin 24 can be withdrawn from the first slot 231 of the limit connecting rod 23, and the limit pin 24 is separated from the limit connecting rod 23, so that the limit pin 24 and the limit connecting rod 23 can be detachably plugged and fixed.
[0053] See also Figure 6 As shown, after the limit latch 24 is removed from the limit link 23, the upper angler 40 can be quickly replaced, and the adjustment lock block 13 and the angler 40 will not interfere with each other, thereby realizing convenient switching between the latch solution and the multi-changeable multi-point lock angler solution. The plug-in end 41 of the angler 40 has a plug-in structure that is basically the same as the plug-in end 241 of the limit latch 24, and is detachably plugged and fixed with the limit link 23.
[0054] According to the inward-opening and inward-tilting hinge 100 of the above-mentioned embodiment of the present application, the limit connecting rod 23 and the limit pin 24 are detachably connected and fixed through a split design, so that the limit pin 24 and the corner turner 40 can be quickly replaced, and the multi-point locks on both sides can be quickly replaced to the variable multi-point locks, without changing the hinge style, which is convenient for customers to select and the configuration scheme is more flexible, which can greatly reduce the product categories and meet the needs of universal modular production of products.
[0055] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
