Description

Technical Field

[0001] This invention relates to the field of rescue window technology, and more particularly to a self-opening rescue window. Background Technology

[0002] Currently, the requirement for building rescue windows is that firefighters must arrive at the fire scene, use a ladder to reach the rescue window location, and then use specialized tools to directly break it open. However, falling objects during the breaking process can easily injure people escaping from the first floor.

[0003] On July 29, 2022, a patent with publication number CN114809887A entitled "An Emergency Rescue Glass Window" was published. It includes an outer window frame for installation within a wall, with an inner window frame installed inside. The inner window frame is rotatably installed on the bottom of the side walls of the outer window frame. Columns are fixedly mounted on both sides of the inner wall of the outer window frame, and a flipping mechanism is provided on each column. This flipping mechanism can rotate the inner window frame outwards to a horizontal position. The glass window can be flipped outwards using this mechanism. However, in the above-mentioned document, the flipping mechanism is used to rotate the inner window frame. Rescuers or those being rescued will step on the inner window frame and its glass when entering or exiting the room through the outer window frame, which could easily lead to irreversible damage. Furthermore, if the glass breaks after being stepped on, it poses a safety hazard, as falling debris could injure people escaping from lower levels. Summary of the Invention

[0004] In view of this, the purpose of this invention is to propose a self-opening rescue window to solve the problem that when the rescue window is damaged, falling debris can easily injure people escaping from lower levels.

[0005] To achieve the above objectives, the present invention provides a self-opening rescue window, comprising a fixing frame, an opening at the top of the fixing frame, a window frame on the inner wall of the opening, a window body fitted inside the window frame, a storage cavity on the fixing frame at the bottom of the window frame, a buffer member at the bottom of the storage cavity, and support members supporting the window body on both sides of the upper part of the storage cavity. Each support member includes a vertical rod fixed in the storage cavity, a support horizontal rod hinged to the upper end of the vertical rod, and a support diagonal rod hinged to the lower end of the support horizontal rod. The lower end of the support diagonal rod is connected to the lower end of the vertical rod by a snap-fit ​​connector. A smoke detector connected to the snap-fit ​​connector is provided on the fixing frame. The smoke detector is connected to a controller. When the smoke detector detects that the smoke concentration is greater than its set concentration, the smoke detector sends an alarm message to the controller, which then controls the snap-fit ​​connector to open, separating the lower end of the support diagonal rod from the lower end of the vertical rod.

[0006] Optionally, the cushioning element includes a foam particle layer, the foam particle layer is wrapped with an elastic bladder, and a rubber pad is provided at the upper end of the foam particle layer.

[0007] Optionally, each of the support members is provided with a reset member on one side. The reset member includes a movable member located in the storage cavity. The movable member is connected to a driving block. The movable member is used to control the up and down movement of the driving block. The side of the driving block located near the middle of the storage cavity is connected to a clamping plate via a connecting spring. The connecting spring is fitted with a multi-section telescopic cylinder. The two ends of the multi-section telescopic cylinder are fixedly connected to the clamping plate and the driving block, respectively. A sloping baffle is provided below the clamping plate. The upper surface of the sloping baffle is higher on the side near the middle of the storage cavity than on the other side. The lower surface of the clamping plate is provided with an inclined surface that cooperates with the sloping baffle. When the movable member drives the driving block to rise, it drives the clamping plate to move upward. When the clamping plate is not in contact with the sloping baffle, the elastic potential energy of the connecting spring causes the clamping plate to contact the side wall of the window. The two clamping plates of the two reset members clamp the window, thereby driving the window to rise and reset the window.

[0008] Optionally, the driving block has a vertically arranged sliding groove on one side near the middle of the storage cavity. A sliding block is slidably connected in the sliding groove. A horizontally arranged through hole is opened in the sliding block. A second inclined limiting block is slidably connected in the through hole. One side of the second inclined limiting block with an inclined slope is arranged facing the driving block. A push rod is connected to the other side of the second inclined limiting block. The other side of the second inclined limiting block is connected to the inner wall of the through hole through a first elastic spring. A first inclined limiting block is arranged between the driving block and the sliding groove to cooperate with the second inclined limiting block. The inclined surface of the first inclined limiting block points towards the middle of the storage cavity. The second inclined limiting block is located on the inclined side of the driving block.

[0009] Optionally, the lower end of the sliding block is connected to the lower part of the sliding groove via a second elastic spring.

[0010] Optionally, the movable component is used to control the up and down movement of the drive block, thereby controlling the window to rise. The movable component can be a drive cylinder, and the movable component is replaceable. The movable component may also include a drive motor. The output end of the drive motor is connected to a drive screw, and a ball bearing connected to the drive block is connected to the drive screw. A guide is provided in the storage cavity, which is parallel to the drive screw, and the ball bearing is slidably connected to the guide.

[0011] Optionally, guide rails are provided on both sides of the window, and guide strips that cooperate with the guide rails are provided on the inner side wall of the storage cavity.

[0012] Optionally, the latching component includes a slot at the lower end of the vertical rod, a first electromagnet disposed in the slot, a receiving groove at the lower end of the supporting inclined rod, a latching block connected to the receiving groove via a telescopic spring and cooperating with the slot, a second electromagnet cooperating with the first electromagnet disposed on the latching block, a telescopic rod sleeved on the telescopic spring, and the two ends of the telescopic rod being fixedly connected to the receiving groove and the latching block respectively. When the smoke detector detects that the smoke concentration is greater than its set concentration, the smoke detector sends an alarm message to the controller, and then the controller controls the magnetism of the first electromagnet to be the same as that of the second electromagnet. The first electromagnet and the second electromagnet, being of the same polarity, repel each other, and the latching block disengages from the slot, separating the lower end of the supporting inclined rod from the lower end of the vertical rod.

[0013] Optionally, a vertical groove is provided below the vertical rod, and a vertical slider connected to the lower end of the supporting inclined rod is slidably connected in the vertical groove, and the receiving groove is formed on the vertical slider.

[0014] The beneficial effects of this invention are as follows: This invention provides a self-opening rescue window. When a fire occurs, the smoke detector detects that the indoor smoke concentration is greater than its set concentration. The smoke detector sends an alarm message to the controller, which then controls the snap-fit ​​connector to open, separating the lower end of the support bar from the lower end of the vertical bar. At this time, the support bar can no longer support the window body within the window frame, and the window body undergoes free fall. The window body falls into the storage cavity, which provides protection for the window body. In addition, the buffer inside the storage cavity cushions the falling window body. When rescuers or those being rescued enter or exit the room through this window frame, the window body will not be damaged due to stepping on it, nor will there be any safety hazard due to the glass breaking after being stepped on.

[0026] To make the objectives, technical solutions, and advantages of the present invention clearer, the present invention will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0027] It should be noted that, unless otherwise defined, the technical or scientific terms used in the embodiments of this invention should have the ordinary meaning understood by those skilled in the art to which this invention pertains. The terms "first," "second," and similar terms used in this invention do not indicate any order, quantity, or importance, but are merely used to distinguish different components. Terms such as "comprising" or "including" mean that the element or object preceding the word encompasses the elements or objects listed following the word and their equivalents, without excluding other elements or objects. Terms such as "connected" or "linked" are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect. Terms such as "upper," "lower," "left," and "right" are used only to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0028] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9 As shown, a self-opening rescue window includes a mounting frame 1. The mounting frame 1 has an opening at its upper part, and a window frame 2 is mounted on the inner wall of the opening. A window body 4 is fitted inside the window frame 2. A storage cavity 3 is formed on the lower end of the window frame 2 and mounted on the mounting frame 1. A buffer is provided at the bottom of the storage cavity 3. Support members 8 supporting the window body 4 are provided on both sides of the upper part of the storage cavity 3. Each support member 8 includes a vertical rod 10 fixed inside the storage cavity 3, and a support is hinged to the upper end of the vertical rod 10. A horizontal bar 9 is supported, and a supporting diagonal bar 11 is hinged to the lower end of the supporting horizontal bar 9. The lower end of the supporting diagonal bar 11 is connected to the lower end of the vertical bar 10 through a snap-fit ​​connector 14. A smoke detector 7 is provided on the fixing frame 1 and connected to the snap-fit ​​connector 14. The smoke detector 7 is connected to a controller. When the smoke detector 7 detects that the smoke concentration is greater than its set concentration, the smoke detector 7 sends an alarm message to the controller, and then the controller controls the snap-fit ​​connector 14 to open, separating the lower end of the supporting diagonal bar 11 from the lower end of the vertical bar 10.

[0029] When a fire occurs, the smoke detector 7 detects that the indoor smoke concentration is greater than its set concentration. The smoke detector 7 sends an alarm message to the controller, which then controls the connector 14 to open, separating the lower end of the support rod 11 from the lower end of the vertical rod 10. At this time, the support rod 9 can no longer support the window 4 inside the window frame 2, and the window 4 undergoes free fall. The window 4 falls into the storage cavity 3, which provides protection for the window 4. In addition, the buffer inside the storage cavity 3 cushions the falling window 4. When rescuers or those being rescued enter or exit the room through the window frame 2, the window 4 will not be damaged due to stepping on it, nor will it pose a safety hazard due to the glass breaking after being stepped on.

[0030] To facilitate buffering of the descending window 4, the buffer includes a foam particle layer, an elastic bladder wrapped around the foam particle layer, and a rubber pad at the upper end of the foam particle layer.

[0031] like Figure 3 , Figure 7 and Figure 9 As shown, each of the support members 8 is provided with a reset member on one side. The reset member includes a movable member 19 located in the storage cavity 3. The movable member 19 is connected to a driving block 20. The movable member 19 is used to control the up and down movement of the driving block 20. The side of the driving block 20 located near the middle of the storage cavity 3 is connected to a clamping plate 32 via a connecting spring 30. A multi-section telescopic cylinder 29 is sleeved on the connecting spring 30. The two ends of the multi-section telescopic cylinder 29 are fixedly connected to the clamping plate 32 and the driving block 20, respectively. The clamping plate 32 is located below... An inclined baffle 31 is provided, with the side of the upper end of the inclined baffle 31 near the middle of the storage cavity 3 being higher than the other side. The lower end of the clamping plate 32 is provided with an inclined surface that cooperates with the inclined baffle 31. When the moving member 19 drives the driving block 20 to rise, it drives the clamping plate 32 to move upward. When the clamping plate 32 is not in contact with the inclined baffle 31, the elastic potential energy of the connecting spring 30 causes the clamping plate 32 to contact the side wall of the window 4. The two clamping plates 32 of the two reset members clamp the window 4, thereby driving the window 4 to rise and reset the window 4.

[0032] When it is necessary to reset the window 4 into the window frame 2, control the moving part 19 to drive the driving block 20 to move upward. When it starts to move upward, the clamping plate 32 abuts against the inclined baffle 31. As the clamping plate 32 moves upward, the clamping plate 32 contacts the side wall of the window 4 under the elasticity of the connecting spring 30. The two clamping plates 32 of the two reset parts clamp the window 4, thereby driving the window 4 to rise and reset the window 4.

[0033] like Figure 3 , Figure 5 and Figure 6As shown, a sliding groove 23 is vertically arranged on one side of the driving block 20 near the middle of the storage cavity 3. A sliding block 22 is slidably connected in the sliding groove 23. A horizontally arranged through hole 24 is opened in the sliding block 22. A second inclined limiting block 25 is slidably connected in the through hole 24. One side of the second inclined limiting block 25 with an inclined slope is arranged facing the driving block 20. A push rod 26 is connected to the other side of the second inclined limiting block 25. The other side of the second inclined limiting block 25 is connected to the inner wall of the through hole 24 through a first elastic spring 27. A first inclined limiting block 21 is arranged between the driving block 20 and the sliding groove 23 to cooperate with the second inclined limiting block 25. The inclined surface of the first inclined limiting block 21 points to... The first inclined limiting block 21 is located on one side of the upper part of the vertical rod 10 and is located on the inclined side of the driving block 20. The driving block 20 moves upward under the drive of the moving member 19. The upper end of the driving block 20 contacts the lower end of the second inclined limiting block 25, thereby driving the second inclined limiting block 25 to move upward. When the second inclined limiting block 25 contacts the first inclined limiting block 21, the second inclined limiting block 25 moves upward at the same time as it is restricted by the first inclined limiting block 21, causing the second inclined limiting block 25 to tilt upward, driving the pushing rod 26 to press against the supporting horizontal rod 9, so that the supporting horizontal rod 9 returns to a horizontal state. Then the locking member 14 locks it in place, and the window 4 moves into the window frame 2. The supporting member 8 supports the window 4.

[0034] The lower end of the sliding block 22 is connected to the lower part of the sliding groove 23 through the second elastic spring 28. When the second inclined limit block 25 is restricted by the first inclined limit block 21, the push rod 26 moves towards the middle of the receiving cavity 3. Then the second inclined limit block 25 is disengaged from the support of the driving block 20, and the sliding block 22 can move downward under the elastic potential energy of the second elastic spring 28.

[0035] The movable component 19 is used to control the up and down movement of the drive block 20, thereby controlling the window 4 to rise. The movable component 19 can be a drive cylinder, and the movable component 19 is replaceable. The movable component 19 may also include a drive motor. The output end of the drive motor is connected to a drive screw, and a ball bearing connected to the drive block 20 is connected to the drive screw. A guide is provided in the storage cavity 3, which is parallel to the drive screw, and the ball bearing is slidably connected to the guide.

[0036] Guide rails are provided on both sides of the window 4, and guide strips are provided on the inner wall of the storage cavity 3 to cooperate with the guide rails, so as to restrict the vertical movement trajectory of the window 4 and prevent the window 4 from deflecting during vertical movement.

[0037] like Figure 3 , Figure 4 and Figure 8As shown, the latching component 14 includes a latching groove 15 formed at the lower end of the vertical rod 10. A first electromagnet is disposed in the latching groove 15. A receiving groove is formed at the lower end of the supporting inclined rod 11. A latching block 16, which cooperates with the latching groove 15, is connected to the receiving groove through a telescopic spring 18. A second electromagnet, which cooperates with the first electromagnet, is disposed on the latching block 16. A telescopic rod 17 is sleeved on the telescopic spring 18. The two ends of the telescopic rod 17 are fixedly connected to the receiving groove and the latching block 16, respectively. When the smoke detector 7 detects that the smoke concentration is greater than its set concentration, the smoke detector 7 sends an alarm message to the controller. The controller then controls the magnetism of the first electromagnet to be the same as that of the second electromagnet. Since the first electromagnet and the second electromagnet are of the same polarity, they repel each other. The latching block 16 disengages from the latching groove 15, separating the lower end of the supporting inclined rod 11 from the lower end of the vertical rod 10.

[0038] A vertical slide groove 12 is provided below the vertical rod 10. A vertical slider 13 connected to the lower end of the support rod 11 is slidably connected in the vertical slide groove 12. The receiving groove is opened on the vertical slider 13 to facilitate the lower end of the support rod 11 to slide up and down along the vertical slide groove 12 and prevent the lower end of the support rod 11 from deflecting.
