Description

Technical Field

[0001] This invention relates to the field of door and window technology, and in particular to a fully openable foldable anti-collision door and window. Background Technology

[0002] In recent years, panoramic windows have rapidly gained popularity, creating ultra-narrow frame and large-screen glass designs that are leading a new trend in home fashion. These panoramic windows offer maximum visibility and ventilation while occupying relatively little space.

[0003] Prior art, such as US Patent Publication No. US20140352220A1, discloses a sliding door structure with sliding and pivoting doors. The sliding panel structure includes a frame with an upper support rail and a lower guide rail. At least one sliding panel is connected between the upper support rail and the lower guide rail. The sliding panel includes a sliding panel pivot axis and an extension for riding in the lower guide rail. The extension prevents undesirable pivoting of the sliding panel about the sliding panel pivot axis. Mutual attraction devices are connected between the sliding panel and the frame, with a first mutual attraction portion connected to the frame and a second mutual attraction portion connected to the sliding panel. Whenever the first mutual attraction portion engages the second mutual attraction portion, a fulcrum is used to tilt the sliding panel. The above-described technical solutions disclose common structures for common panoramic windows.

[0004] Meanwhile, similar technical solutions have also been applied for domestically, such as the positioning and guiding device for a panoramic window disclosed in Chinese patent document CN114109197A, or the panoramic sliding door and window disclosed in Chinese patent document CN119411913A, which includes a door and window frame and multiple door and window sashes. The door and window frame is provided with a first slide rail and a second slide rail, and the door and window sashes are provided with a first support member, an anti-sway member, and a second support member. The first support member and the second support member are located on the upper side of the door and window sashes and slide in contact with the first slide rail, while the anti-sway member is located on the lower side of the door and window sashes and slides in contact with the second slide rail. The end of the first support member is provided with a positioning block in the shape of a semi-cylindrical shape. The first slide rail is provided with a positioning groove in the shape of a semi-cylindrical shape. An obstruction opening is provided on the rear side of the first slide rail for the second support member to pass through. The panoramic sliding door and window of the present invention, through the positioning block and the positioning groove, enables multiple door and window sashes to be positioned, folded, and flipped sequentially, achieving an unobstructed panoramic visual effect within the door and window frame.

[0005] The above design is mainly for small panoramic doors and windows, so the swing is achieved by using a limiting structure and a pulley sliding out. However, if the door or window is heavy and needs to be changed to a panoramic state, the entire sash needs to be moved to one side. At this time, the heavier sash will continuously hit the limiting device, and long-term heavy impact can easily lead to deformation and misalignment. Summary of the Invention

[0006] This invention aims to at least solve one of the technical problems existing in the prior art. To this end, this invention proposes a fully openable foldable anti-collision door and window, which can buffer the impact when the fully open window is pushed or pulled, thereby achieving an anti-collision effect, effectively reducing the possibility of deformation and misalignment, and improving the overall service life.

[0007] According to a first aspect of the present invention, a fully openable foldable anti-collision door and window includes a frame and a sash connected to the frame. A top track is provided at the top of the frame and a bottom track is provided at the bottom of the frame. A panoramic area is formed between the top track and the bottom track. The sash includes a casement sash and at least two sliding sashes. The casement sash is connected to one side of the panoramic area, and the at least two sliding sashes are sequentially arranged and slidably connected to the panoramic area.

[0008] An anti-collision upper limit device is connected to the top track, and an anti-collision lower limit device is connected to the bottom track. The anti-collision upper limit device and the anti-collision lower limit device are located above and below the swing fan, respectively. A first permanent magnet is connected to the anti-collision upper limit device.

[0009] The top of the push-pull fan is connected to a linear rotating shaft, and a second permanent magnet is connected to the linear rotating shaft.

[0010] The fully openable foldable anti-collision door and window according to the embodiments of the present invention has at least the following beneficial effects: by setting an upper anti-collision limiter and an lower anti-collision limiter, the impact force between the linear rotating shaft and each limiter can be effectively reduced, thereby buffering the collision when the fully open window is pushed and pulled, thus achieving the anti-collision effect, effectively reducing the possibility of deformation and misalignment, and improving the overall service life.

[0011] According to some embodiments of the present invention, the bottom of the push-pull fan is connected to a rotating shaft pulley and a main pulley, both of which are connected to the bottom track, and the central axis of the rotating shaft of the rotating shaft pulley coincides with the central axis of the straight rotating shaft.

[0012] According to some embodiments of the present invention, a rotation limiting member is connected to the push-pull fan. When the end of the rotation limiting member extends out and is located in the frame, the push-pull fan is slidably connected to the panoramic area. When the end of the rotation limiting member retracts and is located outside the frame, the push-pull fan can rotate around the linear axis.

[0013] According to some embodiments of the present invention, a housing is sleeved on the linear rotating shaft, and the second permanent magnet is connected in the housing.

[0014] According to some embodiments of the present invention, the housing and the anti-collision upper limiter are both connected to a first anti-collision buffer assembly on the same side, and a second anti-collision buffer assembly is connected to the other side of the housing, and the first permanent magnet is connected to the other side of the anti-collision upper limiter.

[0015] According to some embodiments of the present invention, the first anti-collision buffer assembly includes a support plate, an upper clamping plate, a lower clamping plate, and an elastic buffer member. The upper clamping plate and the lower clamping plate are respectively connected to the top and bottom of the support plate and extend toward the same side of the support plate. The elastic buffer member is connected between the upper clamping plate and the lower clamping plate.

[0016] According to some embodiments of the present invention, at least one connecting hole is spaced apart along the length direction on the elastic buffer member, at least one upper connecting post is correspondingly connected to the upper clamping plate, and at least one lower connecting post is correspondingly connected to the lower clamping plate, wherein the upper connecting post and the lower connecting post are respectively inserted into the connecting hole.

[0017] According to some embodiments of the present invention, a deformation cavity is formed on the end of the elastic buffer member away from the support plate, and an energy-concentrating protrusion is connected to the end of the elastic buffer member away from the support plate.

[0018] According to some embodiments of the present invention, the first anti-collision buffer assembly further includes two side clamps, which are respectively connected between the upper clamp and the lower clamp and enclose an insertion cavity. The upper clamp, the lower clamp, and the side clamps are all made of metal.

[0019] According to some embodiments of the present invention, the structure of the lower anti-collision limiter is the same as that of the upper anti-collision limiter.

[0039] In the description of this invention, unless otherwise explicitly defined, terms such as "set up," "install," and "connect" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this invention in conjunction with the specific content of the technical solution.

[0040] refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 11 as well as Figure 12 As shown, the fully openable foldable anti-collision door and window according to an embodiment of the present invention includes a frame 100 and a sash connected within the frame 100. A top track 110 is provided at the top of the frame 100, and a bottom track 120 is provided at the bottom of the frame 100. A panoramic area is formed between the top track 110 and the bottom track 120. The sash includes a casement sash 210 and at least two sliding sashes 220. The casement sash 210 is connected to one side of the panoramic area, and the at least two sliding sashes 220 are sequentially arranged and slidably connected to the panoramic area.

[0041] A collision-prevention upper limit device 310 is connected to the top track 110, and a collision-prevention lower limit device 320 is connected to the bottom track 120. The collision-prevention upper limit device 310 and the collision-prevention lower limit device 320 are located above and below the swing fan 210, respectively. A first permanent magnet 311 is connected to the collision-prevention upper limit device 310.

[0042] The top of the push-pull fan 220 is connected to a linear shaft 331, which is connected to the top track 110. A second permanent magnet 332 is connected to the linear shaft 331.

[0043] In actual use, by setting the upper limit anti-collision device 310 and the lower limit anti-collision device 320, the impact force between the linear rotating shaft 331 and each limiter can be effectively reduced, thereby buffering the collision when the window is fully opened and pushed and pulled, thus achieving the anti-collision effect, effectively reducing the possibility of deformation and misalignment, and improving the overall service life.

[0044] In some specific embodiments of the present invention, it may also have the following additional technical features: the bottom of the push-pull fan 220 is connected to a rotating shaft pulley 340 and a main pulley 350, both of which are connected to the bottom track 120, and the central axis of the rotating shaft of the rotating shaft pulley 340 coincides with the central axis of the straight rotating shaft 331.

[0045] Specifically, the top and bottom of the push-pull fan 220 are respectively fixedly connected to the rotating shaft sleeve 221, the linear rotating shaft 331 is rotatably connected to the rotating shaft sleeve 221 located at the top of the push-pull fan 220, and the rotating shaft pulley 340 is rotatably connected to the rotating shaft sleeve 221 located at the bottom of the push-pull fan 220.

[0046] In some specific embodiments of the present invention, it may also have the following additional technical features: a rotation limiting member 222 is connected to the push-pull fan 220. When the end of the rotation limiting member 222 extends out and is located in the frame 100, the push-pull fan 220 is slidably connected in the panoramic area. When the end of the rotation limiting member 222 retracts and is located outside the frame 100, the push-pull fan 220 can rotate around the linear rotating shaft 331.

[0047] Specifically, the rotating limiter 222 is an automatic latch. Its specific structure and principle can be found in the automatic lock structure for a folding door disclosed in the patent application filed by the applicant on October 19, 2022, with publication number CN218715865U. The latch extends and retracts through a hardware transmission component and a toggle handle. The hardware transmission component can be a commonly used technical solution in the prior art, and the toggle handle can be a toggle handle disclosed in the patent application filed by the applicant on October 19, 2022, with publication number CN218862298U. By using the above combination, the sliding fan 220 can switch between sliding and open modes. The sliding fan 220 closest to the open mode 210 is magnetically connected to the first permanent magnet 311 of the anti-collision limiter 310 via the second permanent magnet 332, thus achieving a limit fixation. This prevents the sliding fan 220 from becoming unstable and damaging to the frame 100 when it is open, as its center of gravity is not aligned with the track. Similarly, adjacent sliding fans 220 are magnetically connected via their respective second permanent magnets 332, also preventing instability and damage to the frame 100 when they are open, as their center of gravity is not aligned with the track.

[0048] In some specific embodiments of the present invention, it may also have the following additional technical features: a housing 333 is sleeved on the linear rotating shaft 331, and a second permanent magnet 332 is connected in the housing 333.

[0049] Specifically, the housing 333 is a long, hollow, rectangular housing. The length of the housing 333 is aligned with the length of the top track 110. A rotating bushing 334 is connected to the middle of the housing 333. A linear rotating shaft 331 passes through the rotating bushing 334 and is rotatably connected to it. A second permanent magnet 332 is connected to the housing 333 and located on both sides of the rotating bushing 334 along the length of the housing 333. Preferably, there are multiple second permanent magnets 332, which are stacked sequentially.

[0050] In some specific embodiments of the present invention, it may also have the following additional technical features: the housing 333 and the anti-collision upper limit device 310 are both connected to the first anti-collision buffer assembly on the same side, the other side of the housing 333 is connected to the second anti-collision buffer assembly, and the first permanent magnet 311 is connected to the other side of the anti-collision upper limit device 310.

[0051] Specifically, when there are many sliding sashes 220 in the panoramic window, the second anti-collision buffer component of the linear pivot 331 of the sliding sash 220 closest to the casement sash 210 first abuts against the first anti-collision buffer component on the anti-collision upper limit device 310 and buffers and absorbs energy to reduce the impact force under the action of the first anti-collision buffer component. Then, the next sliding sash 220 is pushed to move towards the casement sash 210 in sequence. At this time, the first anti-collision buffer component on the previous sliding sash 220 abuts against the second anti-collision buffer component on the next sliding sash 220 and buffers and absorbs energy to reduce the impact force under the action of the first anti-collision buffer component. This process is repeated, and the impact force is absorbed by the first anti-collision buffer component and the second anti-collision buffer component to achieve the buffering effect.

[0052] In some specific embodiments of the present invention, it may also have the following additional technical features: the first anti-collision buffer assembly includes a support plate 410, an upper clamping plate 420, a lower clamping plate 430 and an elastic buffer member 440, the upper clamping plate 420 and the lower clamping plate 430 are respectively connected to the top and bottom of the support plate 410 and extend toward the same side of the support plate 410 at the same time, and the elastic buffer member 440 is connected between the upper clamping plate 420 and the lower clamping plate 430.

[0053] Specifically, for the anti-collision upper limit device 310, the support plate 410 is connected to the side of the anti-collision upper limit device 310 facing the push-pull fan 220 in the horizontal direction; for the push-pull fan 220, the support plate 410 is connected to the side of the housing 333 away from the anti-collision upper limit device 310.

[0054] In some specific embodiments of the present invention, it may also have the following additional technical features: at least one connecting hole 441 is provided on the elastic buffer member 440 along the length direction, at least one upper connecting post 421 is correspondingly connected to the upper clamping plate 420 of the connecting post, at least one lower connecting post 431 is correspondingly connected to the lower clamping plate 430, and the upper connecting post 421 and the lower connecting post 431 are respectively inserted into the connecting hole 441.

[0055] By connecting the connecting hole 441 and the connecting post, when the elastic buffer 440 is subjected to an impact force, the impact force can be transmitted to the upper clamping plate 420 and the lower clamping plate 430 through the connecting post inserted in the connecting hole 441, thereby achieving the effect of dispersing and absorbing the impact force.

[0056] In some specific embodiments of the present invention, it may also have the following additional technical features: a deformation cavity 442 is opened on the end of the elastic buffer member 440 away from the support plate 410, and an energy-concentrating protrusion 443 is connected to the end of the elastic buffer member 440 away from the support plate 410.

[0057] Specifically, the deformation cavity 442 is used to deform during a collision to absorb the kinetic energy of the impact. Its specific structure is a hollow cavity, which facilitates the absorption of impact kinetic energy through elastic deformation, reducing the probability of deformation of the anti-collision limiter 310 and the housing 333, thus giving it a stronger ability to resist impact forces. Specifically, when the push-pull fan 220 is pushed or pulled at extremely high speed and force and moves towards the swing fan 210 under inertia, the elastic buffer 440, as the first structure to contact the push-pull fan 220, will inevitably experience a huge impact force. The point of concentration of this impact force is inevitably the energy-concentrating protrusion 443 pre-designed at the end of the elastic buffer 440. Under the action of the impact force, the deformation cavity 442 will undergo micro-deflection deformation, specifically bending deformation, which can greatly buffer this impact force. The housing 333 abuts against the elastic buffer 440 and gradually moves towards the support plate 410. When the impact force is completely dissipated, the housing 333 approaches the limit of the anti-collision upper limit device 310 under the magnetic force of each magnet and completes the limit fixation. At this time, the operation of converting the push-pull fan 220 into a casement fan 210 can be completed. When the door and window need to be closed, the housing 333 moves away from the elastic buffer 440, and the deformation cavity 442 will return to its original shape according to the material properties of the elastic buffer 440.

[0058] Furthermore, for ease of description, the elastic buffer 440 is described in structural detail. In reality, the elastic buffer 440 is a single integrated structure: the end of the elastic buffer 440 has a notch, and a plate-like structure is connected to the open end of the notch. The energy-concentrating protrusion 443 is connected to the side of the plate-like structure away from the notch. At this time, the deformation cavity 442 has an oval shape. When the elastic buffer 440 is impacted, due to the presence of the energy-concentrating protrusion 443, it is the first to be impacted and deforms towards the center of the deformation cavity 442, that is, deforms in the notch. During the deformation process, it will pull the plate-like structure and then pull the part of the elastic buffer 440 on both sides of the notch to deform together, so as to absorb more impact force.

[0059] In some specific embodiments of the present invention, it may also have the following additional technical features: the second anti-collision buffer assembly includes a buffer layer 510 and a positioning structure connected in sequence. The buffer layer 510 is a high-density polyurethane foam sponge. One end of the buffer layer 510 is connected to the housing 333. A through hole is provided in the buffer layer 510. The positioning structure includes a pressure plate 530 and a spring 520 connected to the pressure plate 530. The spring 520 is connected to the through hole and to the housing 333. The pressure plate 530 is connected to the other end of the buffer layer 510 and to the spring 520. The pressure plate 530 will not deform when it abuts against the energy-concentrating protrusion 443, thus better transmitting the impact force to the elastic buffer member 440. The presence of the buffer layer 510 and the spring 520 can effectively absorb the impact force transmitted in the opposite direction during the collision, thereby further achieving the buffering effect.

[0060] Preferably, the pressure plate 530 has a groove in the middle that matches the energy-concentrating protrusion 443, and the depth of the groove is one-third of the length of the energy-concentrating protrusion 443. This design improves collision accuracy, thereby increasing the accuracy of force transmission, making buffering and energy absorption more effective, and significantly improving the overall impact resistance.

[0061] In some specific embodiments of the present invention, it may also have the following additional technical features: the first anti-collision buffer assembly further includes two side clamps 450, which are respectively connected between the upper clamp 420 and the lower clamp 430 and enclose an insertion cavity. The upper clamp 420, the lower clamp 430 and the side clamp 450 are all made of metal.

[0062] An insertion cavity, forming a metal channel, is created by the upper clamping plate 420, lower clamping plate 430, and side clamping plate 450. When the second permanent magnet 332 in the housing 333 facing the side of the swing fan 210 enters the insertion cavity, the cavity itself is a conductor and forms a closed circuit. During the insertion of the second permanent magnet 332, the magnetic flux through the area enclosed by the insertion cavity changes (the magnetic flux increases when the magnet approaches). Since the insertion cavity is a metal channel and a closed conductor, the induced electromotive force drives the free electrons to move in a specific direction, forming an induced current. The direction of the current is determined by Lenz's law—the magnetic field of the induced current hinders the insertion of the second permanent magnet 332, thus achieving a further buffering effect.

[0063] In some specific embodiments of the present invention, it may also have the following additional technical features: the structure of the lower anti-collision limiter 320 is the same as that of the upper anti-collision limiter 310. Correspondingly, the same housing 333 as that on the linear rotating shaft 331 is connected to the rotating shaft pulley 340, and a second permanent magnet 332 is also connected inside the housing 333. A second buffer assembly 500 is connected to the side of the housing 333 on the rotating shaft pulley 340 near the swing fan 210, and a first buffer assembly 400 is connected to the other side of the housing 333 on the rotating shaft pulley 340. By analogy with the principle relationship between the linear rotating shafts 331 and between the linear rotating shaft 331 and the upper anti-collision limiter 310, by setting anti-collision buffer functional structures at both the top and bottom of the panoramic area, the anti-collision buffer effect can be further improved, while achieving overall uniformity and improving overall smoothness.

[0064] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
