Description

Technical Field

[0001] This invention relates to a shock-absorbing device, and more particularly to a shock-absorbing refuge chair. Background Technology

[0002] An earthquake is a rapid vibration of the Earth's surface, a frequent natural phenomenon characterized by its wide range, destructive power, difficulty in accurate prediction, and tendency to lead to complex post-earthquake disasters. In recent years, seismic activity has become extremely frequent, with approximately 5 million earthquakes occurring globally each year, significantly impacting society as a whole.

[0003] A major earthquake lasts only a few seconds to tens of seconds from the start to the end of the shaking, making timely earthquake preparedness crucial. Numerous earthquake incidents, both domestic and international, demonstrate that people are most likely to be killed or injured when entering or leaving buildings during the brief moment of an earthquake. Current earthquake preparedness measures include remaining calm during the tremor, taking temporary shelter indoors, and afterwards moving to an open outdoor area away from buildings—these are internationally accepted guidelines for earthquake safety. However, using interior load-bearing walls, corners, tables, or other supports is unreliable; they can only protect against falling debris, not from injuries caused by building collapse.

[0004] To minimize and reduce casualties from earthquakes, research and exploration have been conducted in many fields, including on sleeping beds. This is because most people are asleep during nighttime earthquakes and cannot perceive the danger in time to take shelter or escape, leading to more severe casualties. However, when earthquakes occur during the day, most people are working, studying, or out, and only a small percentage can use earthquake-resistant beds in time, resulting in low utilization. Therefore, designing earthquake protection equipment that can be more widely applied in work and daily life is extremely important. Summary of the Invention

[0005] This invention aims to at least solve one of the technical problems existing in the prior art. To this end, this invention proposes an earthquake-resistant refuge chair, which can be used for self-rescue in the event of an earthquake during work or daily life.

[0006] An earthquake-resistant refuge chair according to an embodiment of the present invention includes a seat cushion, a backrest, a helmet, and two support parts. The seat cushion has two armrests, each armrest having a first receiving cavity to accommodate a human arm, and a first opening on opposite sides of the two first receiving cavities. The bottom of the backrest is rotatably connected to the seat cushion, and the backrest is capable of rotating towards the seat cushion surface of the seat cushion. The helmet is disposed at the top of the backrest. Each support part has a first leg and a second leg. The first leg is vertically disposed at the bottom front end of the seat cushion, and one end of the second leg is rotatably connected to the bottom of the first leg, while the other end abuts against the bottom rear end of the seat cushion. The second leg has a second receiving cavity to accommodate a human leg, and a second opening is provided at the top of the second receiving cavity. The first leg is telescopically adjustable, and when the first leg telescopically extends or retracts, it can cause the end of the second leg connected to the first leg to rise or fall.

[0007] An anti-vibration refuge chair according to an embodiment of the present invention has at least the following beneficial effects:

[0032] Reference Figures 1 to 3 As shown, an embodiment of the shock-absorbing refuge chair of the present invention includes a seat cushion 101, a backrest 102, a helmet 103, and two support parts 104. The seat cushion 101 is provided with two armrests 105, each armrest having a first receiving cavity to accommodate a human arm, and a first opening on opposite sides of the two first receiving cavities. The bottom of the backrest 102 is rotatably connected to the seat cushion 101, and the backrest 102 is capable of rotating towards the seat cushion surface of the seat cushion 101. The helmet 103 is disposed on the top of the backrest 102. Each support portion 104 is provided with a first leg 106 and a second leg 107. The first leg 106 is vertically arranged at the bottom front end of the seat cushion portion 101. One end of the second leg 107 is rotatably connected to the bottom of the first leg 106, and the other end abuts against the bottom rear end of the seat cushion portion 101. The second leg 107 has a second receiving cavity to accommodate the human leg. The top of the second receiving cavity is provided with a second opening. The first leg 106 can be extended and retracted. When the first leg 106 is extended and retracted, it can drive the end of the second leg 107 connected to the first leg 106 to rise or fall.

[0033] The invention described in the above embodiments can be used as an ordinary chair in daily life. In the event of an earthquake, the user sits on the earthquake-resistant refuge chair of this embodiment. The seat cushion 101 and backrest 102 can envelop the body, and the helmet 103 can protect the head. Then, the chair is activated; the first leg 106 retracts, driving the end of the second leg 107 connected to the first leg 106 to rise. The user can place their lower legs into the second receiving cavity of the second leg 107 for leg protection, and then place their arms into the first receiving cavity for arm protection. The body leans forward, and the backrest 102 rotates towards the seat cushion surface of the seat cushion 101, causing the body to fold into a kneeling position as the earthquake-resistant refuge chair folds. This effectively prevents external impact, enabling people to quickly save themselves in the event of an earthquake during daily work or life. Compared to earthquake beds, this invention has a wider range of applications, occupies less space, and has better practical value.

[0034] Specifically, the outer side of the seat cushion 101 is concave to facilitate the fitting of the backrest 102 with the seat cushion 101.

[0035] Understandably, the handrail 105 has a sliding first door panel that opens and closes when it slides. In daily life, the first door panel is in the closed position. During an earthquake, the first door panel opens the opening, and after an arm is placed inside, the first door panel closes the opening, protecting the arm. The inner wall of the first cavity can also be equipped with rubber or airbags to make arm placement more comfortable. Specifically, the sliding of the first door panel is achieved through a sliding structure.

[0036] Understandably, the front end of the seat cushion 101 is provided with a hemisphere 108 corresponding to each support part 104. The hemisphere 108 contains a third receiving cavity, and has two corresponding third openings. A third door panel, which is curved, slides along the inner side of the hemisphere 108. The third door panel can open and close the upper third opening by sliding. When the second leg 107 is raised, it can enter the third receiving cavity through the lower third opening. The hemisphere 108 protects the knees. When the second leg 107 rotates to a vertical or near-vertical position, the second opening of the second leg 107 aligns with the lower third opening of the hemisphere 108. The user can place their leg into the second opening, with their knee positioned in the third opening. The third door panel closes the third opening, thus protecting the knees.

[0037] Understandably, the bottom of the seat cushion 101 is provided with a fourth receiving cavity, and an elastic device 115 is provided inside the fourth receiving cavity. Part of the structure of the elastic device 115 is located outside the seat cushion 101, and when subjected to external impact, the structure of the elastic device 115 located outside the seat cushion 101 can retract into the fourth receiving cavity; a hemisphere 108 is provided at the front end of the elastic device 115, and the first support leg 106 is connected to the bottom of the elastic device 115. The elastic device 115 is provided to buffer pressure.

[0038] Specifically, the elastic device 115 includes a base 116, the top surface of which is inclined downwards along the back of the backrest 102 towards the inwards. An elastic portion, made of shape memory alloy, is provided on the base 116. A spring is installed inside the elastic body 117. A support 118 is provided on the top of the elastic portion, and the support 118 is connected to the bottom of the seat cushion 101. A rotating mechanism is provided inside the support 118 to assist in the rotation of the seat cushion 101. In this embodiment, the hemisphere 108 and the first leg 106 are both mounted on the base 116.

[0039] It is understood that the elastic device 115 is provided with a rotatable ball 119 at the installation position of the first leg 106. The ball 119 is connected to the top of the first leg 106. During the rotation, the ball 119 can drive the first leg 106 and the second leg 107 to rotate forward.

[0040] Reference Figure 2 As shown, it can be understood that the support 104 also includes a leg seat 109, which is telescopically located at the end of the second leg 107 away from the first leg 106. When the second leg 107 is rotated to a standing position, the leg seat 109 extends to contact the ground, providing support for the shock-absorbing refuge chair. At this time, people can put their legs into the second receiving cavity for protection.

[0041] Understandably, the helmet 103 contains a protective face shield 110 that can slide along the inner wall of the helmet 103. A mesh headrest 111 is located at the opening of the helmet 103. When the mesh headrest 111 presses inward against the protective face shield 110, the face shield 110 slides out of the helmet 103 and closes the opening. The helmet 103 also contains a small oxygen exchanger and an air purification filter, capable of providing oxygen to people trapped in an earthquake.

[0042] Understandably, the backrest 102 includes an outer shell, a rotating shaft, and two rows of frames. The interior of the outer shell is filled with synthetic rubber, and the outer shell includes multiple fan-shaped sections, with a first rubber airbag 112 positioned between adjacent fan-shaped sections. The rotating shaft is vertically positioned within the outer shell. The two rows of frames are located within the outer shell and symmetrically positioned on both sides of the rotating shaft, enabling the outer shell to rotate around the rotating shaft. The backrest 102 can extend 45 degrees to both sides to accommodate individuals of different body sizes. The first rubber airbag 112 helps to reduce the pressure of external impacts on the body.

[0043] Understandably, a double airbag structure is provided between the bottom of the backrest 102 and the seat cushion 101. When subjected to external impact, the double airbag structure will deploy to reduce the weight of the human body.

[0044] Understandably, the backrest 102 has two boxes 113, located on the back of the backrest 102 and symmetrically arranged on both sides of the helmet 103. Each box 113 contains a second rubber airbag and a seatbelt 114. The seatbelt 114 has third rubber airbags on both sides along its length. Upon impact, the second rubber airbag deploys to absorb shock and reduce the load on the body. During an earthquake, the seatbelt 114 is pulled out from the box 113 and fastened. The third rubber airbag on the seatbelt 114 not only cushions the pressure but also fills the gaps in the shoulders and neck, catering to different user groups.

[0045] Understandably, the seat cushion 101 is equipped with a vibration sensor, a buzzer, and a positioning system. The vibration sensor can detect earthquakes, allowing people to promptly activate the earthquake-resistant refuge chair of this embodiment for self-rescue. When people are trapped in rubble, the buzzer and positioning system can pinpoint their location.
