Abstract
Description
Technical Field
[0001] This utility model relates to the field of sliding door and window technology, and in particular to a sliding door and window with an anti-pinch structure. Background Technology
[0002] Sliding doors and windows, with their simple and smooth design and flexible and convenient operation, have become a popular type of door and window in modern homes and buildings. They open and close horizontally through sliding tracks without taking up extra indoor or outdoor space, making them especially suitable for small apartments or compact environments.
[0003] Currently, existing sliding doors and windows typically only have basic sliding opening and closing functions. Although they can meet the routine needs of daily ventilation, they cannot effectively slow down the closing speed of the window or prevent the window from pinching a hand when opening, resulting in a safety hazard of pinching a hand during operation. Utility Model Content
[0004] The purpose of this invention is to solve the problem that existing technologies cannot effectively slow down the closing speed of windows when closing, and cannot prevent fingers from being pinched when windows overlap when opening, which leads to the user's fingers being pinched during operation. Therefore, this invention proposes a sliding door and window with an anti-pinch structure.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A sliding door and window with an anti-pinch structure includes:
[0007] A window frame and two windows, the two windows being slidably disposed on the inside of the window frame;
[0008] Both windows are equipped with a buffer mechanism to prevent fingers from being pinched when the windows are closed. The windows are also equipped with an anti-pinch mechanism to prevent fingers from being pinched when one window is open and it abuts against the other window.
[0009] In one possible design, the buffer mechanism includes two grooves respectively opened on opposite sides of the two windows. Two support rods are slidably arranged on both sides of the inner wall of each of the two grooves. Two support rods on the same side are arranged in a cross configuration and hinged by a pin. The other ends of the four support rods on the same window are slidably provided with the same abutment. Two springs are symmetrically fixed on the inner side of the abutment by spring seats. The other ends of the two springs are fixedly connected to the inner wall of the groove by spring seats.
[0010] In one possible design, the anti-pinch mechanism includes a connecting seat fixedly disposed on one side of one of the windows, a lead screw threadedly connected to one side of the connecting seat, and an adjustment knob fixedly disposed at the outer end of the lead screw.
[0011] In one possible design, silicone blocks are fixedly installed on the two opposing sides of the abutments.
[0012] In one possible design, magnet I is embedded above and below the two windows on opposite sides, and magnet II is fixedly installed above and below the inner walls of the window frame on both sides. The positions of magnet I and magnet II correspond to each other, and magnet I and magnet II can be detached and attracted.
[0013] In one possible design, a rubber block is fixedly mounted on one side of the adjustment knob.
[0014] In this application, when a window needs to be opened, hold the edge of one of the windows and gently pull. Since the window is slidably set inside the window frame, it will slide smoothly along the track of the window frame, thus achieving the opening action. After the window is opened, if you want to adjust the distance between the two windows after they are opened according to the actual usage scenario, so as to better avoid the two windows from pinching your hand when they are opened, you can turn the adjustment knob. When the adjustment knob is turned, the screw will rotate and make a linear movement, thereby changing the position of the adjustment knob and thus changing the distance between the two windows after they are opened to meet different anti-pinch requirements. At this time, the adjustment knob is in a suitable position so that no matter which window is opened, it can abut against the adjustment knob to avoid pinching your hand when the two windows are opened, thus ensuring safety. During the process of turning the adjustment knob, the rubber block fixed on one side can add a certain amount of cushioning when the two windows come into contact when they are opened, preventing damage to the windows caused by rigid collision.
[0015] When you need to close the window, push it in the closing direction. As the window moves, it will quickly approach the inner wall of the window frame. The abutment that first contacts the inner wall of the window frame will be pushed to one side by the pressure of the inner wall. As the abutment moves, the support rods on both sides will slide on it, and the other end of the support rod will also slide on the inner wall of the groove, thereby compressing the spring. The spring will generate elasticity, which will play a buffering role, slow down the closing speed of the window and prevent your hand from being pinched. At the same time, the silicone blocks fixed on the opposite side of the two abutments can further enhance the buffering effect and reduce the impact force.
[0016] Then continue pushing the window to bring the magnet I embedded on the top and bottom sides of the window closer to the magnet II on the top and bottom of the inner wall of the window frame. When magnet I and magnet II are close together, they will generate an attractive force, making the window more securely closed inside the window frame, thus completing the entire closing process.
[0017] This utility model has the following beneficial effects:
[0018] In this invention, the buffer mechanism ensures that when the window is pushed to close, the abutment first contacts the inner wall of the window frame and moves under pressure, causing the support rod to slide and compress the spring. The elastic force generated by the spring can effectively slow down the closing speed of the window, thus playing a buffering role. At the same time, the silicone block fixed on the abutment further enhances the buffering effect, greatly reduces the impact force, and effectively avoids the possibility of fingers being pinched due to the rapid closing of the window, providing users with a safer user experience.
[0019] This invention incorporates an anti-pinch mechanism, which allows for flexible adjustment of the knob to change the distance between the two windows after they are opened, ensuring they are in a suitable position. This effectively prevents fingers from being pinched when the two windows overlap, thus guaranteeing the user's safety.
[0020] This invention combines a buffer mechanism with an anti-pinch mechanism, which can effectively slow down the closing speed of the window, reduce the impact force, and prevent fingers from being pinched. It can also adjust the distance between the two windows after they are opened to avoid pinching fingers in an overlapping manner, thus ensuring the safety of users in the process of pushing and pulling doors and windows in all aspects.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0027] In one embodiment
[0028] Reference Figure 1-4 A sliding door / window, comprising:
[0029] The window frame 1 and two windows 2 are installed inside the window frame 1 in a sliding manner, so that the windows 2 can be opened and closed smoothly along the track of the window frame 1 to meet the daily needs for ventilation, lighting and other uses.
[0030] Both windows 2 are equipped with a buffer mechanism, which plays a crucial role in buffering when the windows 2 are closed, effectively preventing hand pinching. Two grooves 3 are respectively formed on the opposite sides of the two windows 2. Two support rods 4 are slidably mounted on both sides of the inner wall of each groove 3, and the two support rods 4 on the same side are arranged in a cross configuration and hinged by a pin. The other ends of the four support rods 4 on the same window 2 are slidably mounted with a common abutment 5. Two springs 6 are symmetrically fixed to the inner side of the abutment 5 via spring seats. The other ends of these two springs 6 are also connected to the inner side of the groove 3 via spring seats. The window 2 is fixedly connected to the wall. When the window 2 is closed, the support 5 will first contact the inner wall of the window frame 1. As the window 2 continues to move in the closing direction, the support 5 will be pressed by the inner wall of the window frame 1, thus moving to one side of the window 2. During the movement of the support 5, the support rods 4 on both sides will slide on the support 5. At the same time, the other end of the support rod 4 will also slide on the inner wall of the groove 3. This series of sliding actions will compress the spring 6. After the spring 6 is compressed, it generates elastic force. This elastic force will act in the opposite direction on the support 5, thereby slowing down the closing speed of the window 2 and playing a buffering role, effectively avoiding the possible hand pinching situation caused by the rapid closing of the window 2.
[0031] To further enhance the cushioning effect, silicone blocks 7 are fixedly installed on the two opposing sides of the abutment 5. The silicone blocks 7 have good elasticity and softness. When the abutment 5 comes into contact with the inner wall of the window frame 1, the silicone blocks 7 can absorb part of the impact force, reduce the impact of rigid collision, and further reduce the risk of pinching hands.
[0032] Magnet I8 is embedded above and below the two windows 2 on the opposite sides. Magnet II9 is fixedly installed above and below the inner walls of the window frame 1 on both sides. The positions of magnet I8 and magnet II9 correspond to each other, so that they can be disengaged and attracted.
[0033] When closing window 2, the buffer mechanism first buffers and slows down the closing speed of window 2. Then, window 2 is pushed further, so that magnet I8 and magnet II9 come close to each other and a magnetic force is generated between them. This magnetic force enables window 2 to be closed more securely in window frame 1 (while the abutment 5 will retract into groove 3), enhancing the sealing and stability of the door and window.
[0034] This application can be used in the field of sliding door and window technology with anti-pinch structure, and can also be used in other fields applicable to this application.
[0035] In another embodiment
[0036] Reference Figure 4 A sliding door and window with an anti-pinch structure is disclosed, applying the field of sliding door and window technology with an anti-pinch structure. An anti-pinch mechanism is also provided on the window 2. The function of this anti-pinch mechanism is to prevent a hand from being pinched when one window 2 is opened and abuts against the other window 2. The anti-pinch mechanism includes a connecting seat 10 fixedly disposed on one side of one of the window 2. A lead screw 11 is threadedly connected to one side of the connecting seat 10. An adjustment knob 12 is fixedly disposed on the outer end of the lead screw 11. During use, the user can rotate the adjustment knob according to actual needs. Button 12: Since the adjustment knob 12 is fixedly connected to the lead screw 11, rotating the adjustment knob 12 will cause the lead screw 11 to rotate accordingly. Since the lead screw 11 is threadedly connected to the connecting seat 10, the lead screw 11 will make linear motion while rotating, thereby changing the position of the adjustment knob 12. By adjusting the position of the adjustment knob 12, the distance between the two windows 2 after they are opened can be adjusted. When adjusted to a suitable position, no matter which window 2 is open, the adjustment knob 12 can abut against the other window 2, effectively preventing the hand from being pinched when the two windows 2 are intersecting, and ensuring the safety of the user.
[0037] In order to increase the buffer when the two windows 2 are opened and come into contact, and to prevent damage to the windows 2 caused by rigid collision, a rubber block 13 is fixedly installed on one side of the adjustment knob 12. The rubber block 13 has a certain elasticity and buffering performance. When the adjustment knob 12 comes into contact with another window 2, the rubber block 13 can absorb part of the impact force and reduce the damage to the window 2 caused by the collision.
[0038] The accompanying drawings in this application are for illustrative purposes only. The dimensions and shapes of the components shown are not actual limitations but are merely schematic representations. In actual implementation, the components can be reasonably configured and adjusted according to specific needs and actual conditions.
[0039] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
