Description

Technical Field

[0001] The invention relates to a bed, in particular to an anti-vibration bed which is easy to popularize and belongs to civilian living furniture. Background Art

[0002] People in the earthquake zone rarely build tents because the weather is too cold. Hiding in the house is at risk of being hit, so they just run out to an open area when the house shakes. Some buildings are too high and they can't run downstairs during an earthquake, so they just stop. In today's advanced modern technology, people still don't have practical earthquake-proof measures in the face of earthquakes. There are no videos or news about the use of earthquake-proof beds or other earthquake-proof facilities. Facts have proved that people are so helpless in dealing with earthquakes. For people in the earthquake zone, there are no practical earthquake-proof measures and facilities. If there is a practical and easy-to-popular earthquake-proof space in the earthquake zone, it is very necessary. Summary of the invention

[0003] The task of the present invention is to provide a shockproof bed which is easy to popularize, has good shockproof effect, is low in price and is easy to manufacture on a large scale.

[0004] The technical solution adopted by the present invention to solve its technical problems is: an earthquake-proof bed that is easy to popularize, comprising a bed board and a bed top, wherein the bed board and the bed top are horizontally opposite and parallel to each other, and there is a main vertical column at each of the four corners of the bed board, one end of the main vertical column is vertically fixed to the bed board, and the other end has a locking tongue or a wooden or bamboo straight rod to clamp the bed top and keep the stability of the bed top, when the locking tongue retracts or the easily broken wooden or bamboo straight rod is damaged by the impact of the collapsed bricks and stones of the house, the bed top will lose the supporting force of the main vertical column and fall freely; the locking tongue is on an electric lock, and the electric lock is controlled by an earthquake early warning device; the upper and lower sections of the main vertical column are made of different materials, the upper section has low strength, and the lower section has high strength, and the ratio of the lengths of the upper and lower sections is 1:3 to 1:1; at the edge of the bed board, in addition to the four fixed main vertical columns, , there are also several secondary vertical columns distributed in the direction parallel to the main vertical column, one end of the secondary vertical column is vertically fixed on the edge of the bed board, the height of the secondary vertical column is the same as the height of the lower section of the main vertical column with greater strength, and the material and cross-sectional shape of the secondary vertical column are the same as those of the lower section of the main vertical column with greater strength; in the horizontal direction, there are several horizontal columns connected to the main vertical column and the secondary vertical columns, and the connection structure is that, on the four longitudinal surfaces of the edge of the bed board, except for an entrance and exit for people to get on and off the bed, the four longitudinal surfaces of the edge of the bed board are all surrounded by the horizontal columns, the main vertical columns and the secondary vertical columns, forming a square mesh enclosure of the edge of the bed, and the height of the enclosure is the same as that of the secondary vertical columns; there is a stool or wooden frame support between the bottom of the bed board and the floor, and the height of the stool or wooden frame support is suitable for people to get on and off the bed. The bed board and the bed top are composed of a square mesh frame and wooden boards fixedly laid on the frame. The material and cross-sectional shape of the frame are the same as those of the secondary vertical columns. The material of the lower section of the main vertical column, the secondary vertical column and the horizontal column with high strength is metal, and the outer surface is also metal, and the outer surface is either aluminum-plastic, wood or plastic material; the upper section of the main vertical column with low strength is a paulownia or poplar cylinder, or a plastic round tube, or a thin metal tube; the square mesh enclosure or the square mesh frame is welded from metal tubes, and for the sake of popularization, it is preferably constructed by scaffolding and fixed by scaffolding buckles, and the wooden boards are fixed to the frame by wire or screws, rivets, or bonding, preferably by wire; in order to make the square mesh enclosure or the square mesh frame more solid, metal tubes are installed on the diagonal of the "square" of the square mesh enclosure or the square mesh frame for reinforcement.When an earthquake occurs, the lock tongue retracts or the straight rod breaks, and the bed top will lose its support force and fall on the horizontal column at the top of the square mesh enclosure. There are four horizontal columns in the front, back, left and right directions of the square mesh. An axis is installed in the middle of each horizontal column. One end of the axis is connected to a hook. The size and strength of the hook can hook the round tube on the bed top. The other end of the axis is connected to a right-angle hook. The weight of the hook is greater than the right-angle hook, so that the sum of the moments on the axis is on one side of the hook, so that the hook is in an open state. When the bed top falls, the round tube on the bed top just presses the right-angle hook, and the torque generated thereby causes the hook to hook the round tube on the bed top, so that the bed top and the square mesh enclosure become one. For the sake of beauty, climbing simulated plants, flowers, birds and insects can be installed on the lower member, upper member and vertical enclosure.

[0005] The working principle of the present invention is: one side of the bed board is tightly and firmly combined with the four sides of the square mesh enclosure, wherein there is an entrance and exit for people to get on and off the bed in front of the square mesh enclosure, and this entrance and exit does not affect people climbing into the bed regardless of whether the top of the bed is raised by the main vertical column or hooked by the hook in the middle of the horizontal column. This means that whether the top of the bed falls down during an earthquake does not affect entering the bed, and in fact, people can avoid danger by getting into the bed. There are two ways for the top of the bed to fall down, one of which is to rely on the lock tongue on the electric control lock controlled by the earthquake early warning device, which usually limits the top of the bed. During an earthquake, the lock tongue retracts, the top of the bed limit disappears, and falls above the square mesh enclosure; the second is that the top of the bed relies on the wooden or bamboo straight rods on the upper main vertical column to clamp the top of the bed, for example, one or more chopsticks are nailed to the upper main vertical column to limit the top of the bed from falling. During an earthquake, the falling bricks will generate thrust, destroying one or several chopsticks, and the top of the bed will also fall onto the square mesh enclosure. The fallen top of the bed is hooked by the hook connected to the middle of the horizontal column, so that the bed board, the square mesh enclosure and the top of the bed become one, exposing the upper section of the main vertical column. Since this section is made of a paulownia or poplar wood cylinder, or a plastic round tube, or a thin metal tube, the bricks dropped by the earthquake can be smashed or knocked down, but will not affect the person in the bed. If the building collapses, including the floor, it will also collapse. At this time, the stool or wooden frame support under the bed board will also be detached. The floor or large wall will exert external force on the bed board, the enclosure and the top of the bed. The resultant force of the external force is to push the enclosure to the area with a small resultant force. This area is exactly the gap area of ​​the collapsed building. Since the enclosure itself has shrunk in size, it is more susceptible to a small resultant force and remains intact in a small space. Buildings will be destroyed in a magnitude 5 earthquake, buildings may collapse in a magnitude 6 earthquake, buildings will be severely damaged in a magnitude 7 earthquake, and most buildings will be destroyed in a magnitude 8 earthquake. In the Wenchuan earthquake data, there is still a lot of space in the collapsed buildings. Small size and solidity can be earthquake-proof enough. As long as the bed board, enclosure and bed top are made strong enough, it will become a "Noah's Ark" to protect people's safety. In order to prevent the top of the bed from jumping high under the impact of the longitudinal or transverse waves generated by the earthquake, a limit pin is installed on the upper main vertical column above the top of the bed. Since earthquakes occur instantly over a large area, an earthquake affects thousands of households, and it is not enough for a store or a factory to have more than a dozen or even hundreds of earthquake-proof beds to meet the needs. This is also the root cause of the fact that neither the official earthquake bureau nor the private relief organization has introduced a strong earthquake-proof measure so far. After the earthquake, they also sent quilts, bread and other supplies, especially in winter. Therefore, it is very necessary to quickly organize materials, quickly form, and be implemented by the public to quickly achieve group earthquake-proof effects.The present invention recommends four types of application materials: the first is scaffolding pipes, which have been cut into specified lengths when leaving the factory or warehouse, such as 2.1 meters (length), 1.6 meters (width), 1.1 meters (vertical enclosure door), etc.; the second is wooden board materials with a thickness of 2.5 cm to 3.5 cm, and the commonly used length is 2.1 meters; the third is scaffolding buckles; the fourth is the wire for tying wooden boards. The tools used are simpler, just two types: an adjustable wrench and a pair of pliers. The materials can be purchased directly in cities at the county level or above. If it is inconvenient to transport, they can be purchased directly online. According to the actual cost of the inventor, a 2-meter-long and 1.5-meter-wide bed has a manufacturing cost of about 1,200 yuan for the materials of the present invention, and one person can complete the installation in two or three days. Since the scaffolding itself can be built at a height of more than 24 meters, the strength of the scaffolding and its buckles can meet the earthquake resistance requirements, and the present invention achieves an unprecedented effect of group earthquake resistance. For earthquake early warning devices, reference may be made to an earthquake early warning action device (CN201120211716.8) developed by the inventor. Figure 1 To detect earthquake signals, Figure 2 Output signal to control an electric lock.

[0006] The beneficial effects of the present invention are that it has high bearing strength, quick action, energy absorption, convenience and comfort, and has the smallest volume after being enclosed into a fixed whole, and moves to a safe area with small force under the action of impact combined external force. The material cost is low, it can be manufactured by all people, and it is easy to popularize. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0011] Figure 1This is a pre-earthquake structural diagram of an embodiment of the present invention. It includes a bed board 1 and a bed top 2. For ease of observation and understanding, the bed board 1 and the bed top 2 are not laid with wooden boards. The bed board 1 and the bed top 2 are horizontally opposite and parallel to each other. There is a main vertical column 3 at each of the four corners of the bed board 1. One end of the main vertical column 3 is vertically fixed to the bed board 1, and the other end has a lock tongue or a wooden or bamboo straight rod 4 to clamp the bed top 2 and keep the bed top 2 stable. When the lock tongue retracts or the easily broken wooden or bamboo straight rod 4 is damaged by the impact of the collapsed masonry, the bed top 2 will lose the support of the main vertical column 3 and fall freely. The lock tongue is on an electric lock, which is controlled by an earthquake early warning device. The upper and lower sections of the main vertical column 3 are made of different materials, the upper section has low strength, the lower section has high strength, and the length ratio of the upper and lower sections is 1:3 to 1:1; at the edge of the bed board 1, in addition to the four fixed main vertical columns 3, there are also several auxiliary vertical columns 5 distributed in the direction parallel to the main vertical columns 3, one end of the auxiliary vertical column 5 is vertically fixed on the edge of the bed board 1, the height of the auxiliary vertical column 5 is the same as the height of the lower section of the main vertical column 3 with high strength, and the material and cross-sectional shape of the auxiliary vertical column 5 are the same as the lower section of the main vertical column 3 with high strength. In the horizontal direction, there are several horizontal columns 6 connected to the main vertical column 3 and the auxiliary vertical column 6, and the connection structure is that on the four longitudinal surfaces of the edge of the bed board 1, except for an entrance and exit for people to get on and off the bed, the four longitudinal surfaces of the edge of the bed board 1 are all surrounded by horizontal columns 6, main vertical columns 3 and auxiliary vertical columns 5, forming a square mesh enclosure of the edge of the bed, and the height of the enclosure is the same as the height of the auxiliary vertical column 6. A stool or a wooden frame is provided between the bottom of the bed board 1 and the floor to support it. The height of the stool or the wooden frame is suitable for people to get on and off the bed conveniently. Figure 1 No stool or wooden frame support is drawn. The bed board 1 and the bed top 2 are composed of a square mesh frame and wooden boards fixedly laid on the frame. The frame material and cross-sectional shape are the same as those of the secondary vertical column 5. The material of the lower section of the main vertical column 3 with high strength, the secondary vertical column 5 and the horizontal column 6 is metal, and the outer surface is also metal, and the outer surface is either aluminum-plastic, wood, or plastic. The upper section of the main vertical column 3 with low strength is a paulownia or poplar cylinder, or a plastic round tube, or a thin metal tube. The square mesh enclosure or the square mesh frame is welded by metal tubes. In order to facilitate popularization, it is preferably constructed by scaffolding, fixed by scaffolding buckles, and the wooden boards are fixed to the frame by wire or screws, rivets, or bonding, preferably by wire. Figure 1 The strip skeleton in the figure can be regarded as a metal tube or a scaffold. When regarded as a scaffold, Figure 1 The “·” in the figure is the scaffolding buckle 7. Figure 1 In the lower right corner of the figure, only one scaffolding buckle 7 is drawn, and the others are marked with “•” to make the picture less cluttered. In order to prevent the bed top 2 from jumping high under the impact of longitudinal waves or transverse waves generated by an earthquake, a limit pin 8 is installed on the upper main vertical column 3 above the bed top 2.

[0012] Figure 2 The schematic diagram of the hook 10 on the horizontal column 6 hooking the round tube on the top of the bed 2. For the sake of clarity, Figure 2 The right side shows the positional relationship between the round tube 11, horizontal column 6 and shaft 9 on the bed top 2 and the right-angle hook 12 and hook 10 in the cross-section state. When an earthquake occurs, the lock tongue or wooden or bamboo straight rod 4 loses its supporting function, and the bed top 2 falls on the horizontal column 6 at the top of the square mesh enclosure. There are four horizontal columns at the top in the front, back, left and right directions. A shaft 9 is installed in the middle of each horizontal column 6. One end of the shaft 9 is connected to a hook 10. The size and strength of the hook 10 can hook the round tube 11 on the bed top 2. The other end of the shaft is connected to a right-angle hook 12. The weight of the hook 10 is greater than the right-angle hook 11, so that the sum of the torque on the shaft 9 is on one side of the hook 10, so that the hook 10 is in an open state. When the bed top 2 falls, the round tube 11 on the bed top 2 just presses the right-angle hook 12. The torque generated thereby causes the hook 10 to hook the round tube 11 on the bed top 2, so that the bed top 2 and the square mesh enclosure become one.

[0013] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
