Description

Technical Field

[0001] The invention relates to a bed, in particular to an energy-absorbing and shock-proof bed with a rapidly reduced volume, belonging to civilian living furniture. Background Art

[0002] Although various types of shockproof beds have been invented, there are still problems of one kind or another. For example, the size of a double bed is too large, and the flap shockproof bed may flip over before the person is in bed under automatic control, or the bedding may get stuck and the flap cannot flip. In addition, shockproof beds are all professionally manufactured by factories and enterprises, with low sales and high prices, making them difficult to be accepted by people, let alone popularized. Summary of the invention

[0003] The task of the present invention is to provide an energy-absorbing and shock-proof bed with a rapidly reduced volume, good shock-proof effect, low price, easy processing and molding, and easy large-scale application.

[0004] The technical solution adopted by the present invention to solve its technical problems is: an energy-absorbing and shock-proof bed with a rapidly reduced volume, comprising a bed board and a bed top, wherein the bed board and the bed top are opposite to each other on two sides and are parallel to each other, and the outer edge of the bed board between the bed board and the bed top is perpendicular to the surrounding vertical surfaces of the bed board. The three-dimensional shape of the square vertical enclosure is a four-sided square enclosure with a notch, and its horizontal section is a shape of a "mouth" shape with a notch on the long side, and the notch is an entrance and exit for people to get on and off the bed; the four square vertical enclosures are located between the bed board and the bed top, and the space between the bed board and the bed top is divided into three parts, namely: an upper space, a vertical enclosure, and a lower space, and the spatial height of each of the three parts is 50 cm to 80 cm, there are energy absorbing pads between the bottom of the bed board and the floor and above the top of the bed, the lower space between the bed board and the vertical enclosure is supported by a lower member, and the lower member has three forms: one is to fix a support rod upward near each of the four corners of the edge of the bed board, the other end of the support rod extends to the lower cylinder fixed at the lower edge of the vertical enclosure, the two ends of the lower cylinder are open, and a rope is tied inside the lower cylinder; the second form of the lower member is to axially connect a straight rod at the relative position of the bed board and the lower edge of the vertical enclosure, and the other ends of the corresponding two straight rods are axially connected together, and there are at least four such connection forms distributed between the bed board and the lower edge of the vertical enclosure, and two of them form a pair of "< >" shape, and another pair of "< >" shapes are fixed on the lower edges of the bed board and the vertical enclosure with opposite axes, and a rope is tied to the two horizontal diagonals of the "< >" shape for tensioning; the third form of the lower component is a scissor-type support frame formed by crossing two straight rods and connecting them in an "X" shape, only one end of the straight rod constituting the scissor-type support frame is connected to the edge of the bed board, and only one end of the remaining other straight rod is connected to the corresponding lower edge of the vertical enclosure, and a rope is tied to the horizontal side of the "X"-shaped scissor-type support frame for tensioning; the effect of the lower component is to keep the height of the lower space unchanged.The upper space between the vertical enclosure and the bed top is supported by an upper member, and the upper member has three forms: one is that a support rod is fixed downward near each of the four corners of the edge of the bed top, and the other end of the support rod extends into an upper cylinder fixed at the upper edge of the vertical enclosure, and the two ends of the upper cylinder are open, and a rope is fastened inside the upper cylinder; the second form of the upper member is that a straight rod is axially connected at each relative position of the bed top and the upper edge of the vertical enclosure, and the other ends of the corresponding two sections of the straight rod are axially connected together, and there are at least four such connection forms distributed between the bed top and the upper edge of the vertical enclosure, two of which form a pair of "< >" shapes, and are axially fixed on the bed top and the upper edge of the vertical enclosure facing each other with the other pair of "< >" shapes, and in the "< >"-shaped horizontal two diagonals are tied with a rope for tensioning; the third form of the upper component is a scissor-type support frame formed by crossing two straight rods and then pivotally connected in an "X" shape, wherein only one end of the straight rod constituting the scissor-type support frame is pivotally connected to the edge of the bed top, and only one end of the remaining other straight rod is pivotally connected to the corresponding upper edge of the vertical enclosure, and a rope is tied in the horizontal direction of the "X"-shaped scissor-type support frame for tensioning; the effect of the upper component is to keep the height of the upper space unchanged. The materials constituting the bed board, bed top and vertical enclosure are wood, steel, a mixture of steel and wood, or a mixture of steel and plastic. The skeleton of the materials is steel, and they are connected by welding, bolting, riveting or snapping. The structure of the energy-absorbing pad is formed by vertically crossing cardboard or wooden plywood or five-ply wood, similar to the heat dissipation fin structure of a car or an air-conditioning condenser. The energy-absorbing pad under the bed board is independent, with a height between 30 cm and 80 cm, and the energy-absorbing pad above the bed top is also independent, with a height between 30 cm and the roof of the house where the shockproof bed is installed.In order to facilitate promotion, rapid prototyping, implementation by the public, and rapid realization of group earthquake protection effects, it is recommended to use scaffolding pipes as frame materials, the material frame of the bed board, bed top and vertical enclosure is scaffolding pipes, and the frame is connected and fixed with scaffolding buckles; scaffolding pipes as hypotenuses are installed in the right-angled planes at the right angles of the frames of the bed board, bed top and vertical enclosures, and are fixed to the scaffolding pipes at the right-angled edges with oblique fasteners; wooden boards are laid on the scaffolding constituting the bed board and bed top, and the wooden boards are fixed to the scaffolding with wire or screws, rivets, or bonding to form the bed board and bed top, and the upper cylinder and the lower cylinder are connected with scaffolding buckles The support rods of the edge of the bed board are upward scaffolding pipes, and a rope fixed in a scaffolding buckle with a screw loosened is inserted at the end of the upward scaffolding pipe, and the scaffolding buckle is fixed to the lower end of the frame of the vertical enclosure; a support rod is fixed downward near the four corners of the edge of the top of the bed, and the support rods are downward scaffolding pipes, and a rope fixed in a scaffolding buckle with a screw loosened is inserted at the end of the upward scaffolding pipe, and the scaffolding buckle is fixed to the upper end of the frame of the vertical enclosure; the support rods of the downward scaffolding pipes and the support rods of the upward scaffolding pipes are not installed in a vertical line. The strength of the tensioned rope is related to the task undertaken. The thickness and number of strands of the rope with the minimum force that does not destroy the support form are obtained through experiments. The number of strands of the rope actually tied is 1-5 times the number of strands of the minimum force. The rope is either concentrated on a unified limit rod, and the limit rod is controlled by an earthquake early warning device. When the local vibration reaches the specified amplitude or intensity, the earthquake early warning device causes the limit rod to move, or the limit rod is manually pulled to release the tension of the rope concentrated here. The rope loses tension, and the support rod, the "< >"-shaped diagonal straight rod, and the "X"-shaped scissor support frame that are limited disappear under the gravity of the object above. The upper space and the lower space of the bed top, the vertical enclosure, and the bed board are shrunk into one. On the bed board on the inner side of the projection of the bed board in the vertical direction of the vertical enclosure, a wooden bar guardrail with a circumference height of 15 cm to 30 cm is installed to protect the bedding or human body in the bed board from affecting the combination of the vertical enclosure and the bed board. Fixed serrated hooks are axially connected at the upper and lower ends of the vertical enclosure edge, and the corresponding edges of the bed board and the bed top are provided with serrated hooks with restoring springs, so that when the vertical enclosure is combined with the bed board or the bed top, the two opposite serrated hooks are locked, and when the hook is rotated in the opposite direction of the spring force, the two serrated hooks are disengaged.

[0005] The working principle of the present invention is as follows: the protection area of ​​the present invention includes a bed board, a vertical enclosure and a bed top. Under normal circumstances, the bed board is supported by an energy-absorbing pad below, the vertical enclosure is supported by a lower member placed on the bed board, and the bed top is supported by an upper member placed on the vertical enclosure. The height of the energy-absorbing pad under the bed board is between 30 cm and 80 cm, and it is appropriate to make it convenient for people to get on and off the bed with the total height of the bed board from the floor. In order to have a wide field of vision and beautiful appearance, the vertical enclosure is preferably not a flat structure, but a frame structure, or hollow carvings are made in its frame structure. The structure and principle of the upper member and the lower member are the same. When an earthquake occurs, the tension of the rope that binds the upper member and the lower member disappears, and the bed top and the vertical enclosure are only subject to gravity. Under the action of gravity, they fall freely. It is calculated that the height is almost zero in less than 1 second, and the upper space and the lower space disappear. The bed board, the vertical enclosure and the bed top become a closed space under the combination of the sawtooth hook, so that the action of the present invention is the fastest. The manufacturing process, including the bed board, vertical enclosure and bed top, must have sufficient strength to become a shock-absorbing "Noah's Ark". The vertical enclosure has an entrance and exit. Assuming that people are not in bed during the day but working in the building, regardless of whether the bed top and bed board are closed or not, the entrance and exit door is always there, and people can get into this closed space. When a house or building collapses, the closed space composed of the bed board, vertical enclosure and bed top is subjected to uneven forces on all sides. This closed space will move in the direction of the combined force, which is the idle space of the collapsed room. In addition, the energy-absorbing pads under the bed board and on the top of the bed will reduce the impact force on this closed space. The upper and lower energy-absorbing pads are not fixed to the closed space composed of the bed board, vertical enclosure and bed top. When this closed space moves under the combined external force, the energy-absorbing pads are thrown away, so that the protected space is minimized and the probability of being impacted is reduced. The fact that children can easily survive in a collapsed room proves this truth. Many earthquake-proof beds are designed with legs fixed on the bed board. Since the legs are more likely to be subjected to external forces, the legs will damage the bed board when the house collapses. The present invention avoids this shortcoming. The structure of the energy-absorbing pad is formed by vertically crossing cardboard or wooden plywood or five-ply board, which is similar to the structure of a car radiator. Of course, it is not as dense as a car radiator. The energy-absorbing pad does not deform when you are on the bed. Only when it is subjected to external forces such as the collapse of the house will it produce irreversible deformation. Since earthquakes occur instantly over a large area, an earthquake affects thousands of households. It is not possible 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 reason why neither the official earthquake bureau nor the private relief organization has introduced a strong earthquake-proof measure so far. After the earthquake, they only sent quilts, bread and other materials, especially in winter. Therefore, it is very necessary to quickly organize materials, quickly form them, and implement them for the public to quickly achieve group earthquake-proof effects.The present invention recommends the use of four types of materials to solve the problem: 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 such as 2.1 meters; the third is scaffolding buckles; the fourth is the wire for tying wooden boards. The tools used are simpler, there are only two types: an adjustable wrench and a pair of pliers. The energy-absorbing pad under the bed board can be made of plywood plugged into square shapes like air-conditioning condensers, and glued firmly to achieve the usual weight without deformation, and irreversible deformation will occur when the weight is greater than 2-4 times the usual weight. The energy-absorbing pad under the bed board can also be replaced by the original wooden bed. Putting cartons containing clothes under the bed can also continue to absorb energy after the bed legs are broken. If you use it yourself, the energy-absorbing pad on the top of the bed can be directly replaced by a carton containing clothes, which can also save space for storing clothes. For beauty, a curtain is added to the outward edge above the top of the bed to cover the carton. The materials can be directly purchased in cities at the county level or above. If it is inconvenient to transport, you can buy it directly online. For beauty, climbing simulated plants, flowers, birds and insects can be installed on the lower member, upper member and vertical enclosure. According to the actual cost of the inventor, a bed of 2 meters long and 1.5 meters wide has a manufacturing material cost of about 1,200 yuan, 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 buckle construction is large enough to be comparable to a standard earthquake-proof bed, and the present invention achieves an unprecedented effect of group earthquake prevention. For the earthquake early warning device, reference can be made to the inventor's earthquake early warning action device (CN201120211716.8). Figure 1 To detect earthquake signals, Figure 2 An output signal is used to control an electric lock, and the lock tongue of the electric lock is placed on the limit rod. When an earthquake occurs, the tension of all ropes on the limit rod can be released, so that the bed top and the vertical enclosure fall to the bed board under the action of gravity, and the bed top, the vertical enclosure and the bed board are fixed together by a serrated hook to protect the people inside.

[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 in a fixed whole, and moves to a safe area with low force under the action of the combined external force. The material cost is low, and it can be manufactured by the whole people, changing the passive situation of "no need to run in a small earthquake, and can't run in a big earthquake". Once an earthquake occurs, a practical and feasible shock-absorbing space can be quickly made. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] Figure 1This is a pre-earthquake structural diagram of an embodiment of the present invention. The earthquake-proof bed includes a bed board 1 and a bed top 2. The bed board 1 and the bed top 2 are opposite to each other. There are four square vertical enclosures 3 on the vertical surfaces around the outer edge of the bed board 1. The gap in front of the vertical enclosure 3 is an entrance and exit for people to get on and off the bed; there is an energy-absorbing pad 4 under the bed board 1. The lower space between the bed board 1 and the lower edge of the vertical enclosure 3 is supported by a lower component. A support rod 5 is fixed upward near the four corners of the edge of the bed board 1. The other end of the support rod 5 extends to the lower cylinder 6 fixed on the lower edge of the vertical enclosure 3. The two ends of the lower cylinder 6 are open, and a rope 7 is tied inside the lower cylinder 6. The lower cylinder 6 has the end of the support rod 5 facing upward, and the upper cylinder 8 has the end of the support rod 5 facing downward. The end of the support rod 5 is fixed by the rope 7, which is fixed on the lower cylinder 6. The tension of the rope 7 is limited. When an earthquake occurs, the rope 7 will be violently impacted by the support rod 5 and broken when the bricks and stones fall down, so that the vertical enclosure 3 falls on the bed board 1 under gravity. The principle of the upper cylinder 8 is the same as that of the lower cylinder 6. The rope in the upper cylinder 8 and the lower cylinder 6 can also be connected to the cylinder at one end, and the other end is connected to the limit rod of the earthquake early warning action device. The upper cylinder 8 and the lower cylinder 6 keep a distance of 0.5 cm to 2.5 cm around the support rod 5 therein, and the purpose is to ensure the smoothness of the support rod 5 when it falls. The reason for using a cylinder instead of a ring is to prevent the support rod 5 from being detached from the upper cylinder 8 or the lower cylinder 6 during the longitudinal wave or transverse wave of the earthquake. If necessary, tie wire limiters between the bed board 1 and the lower edge of the vertical enclosure 3, and between the bed top 2 and the upper edge of the vertical enclosure 3; or add blocks to the support rod 5, the upper cylinder 8, and the lower cylinder 6, the size and direction of the block are to prevent the support rod 5 from detaching from the upper cylinder 8 or the lower cylinder 6. Figure 1 In the figure, the material frames of the bed board 1, the bed top 2 and the vertical enclosure 3 can be welded with metal round tubes or metal square tubes, and the outer surface can be decorated with plywood, five-ply board, aluminum-plastic board or plywood. In order to block the line of sight as little as possible, the frame of the vertical enclosure 3 should not be too wide while ensuring its firmness.

[0014] Figure 2 yes Figure 1 Schematic diagram of the structure in the state after the earthquake. At this time, the support rod 5 is no longer bound by the rope, so that the bed board 1 is closed together with the vertical enclosure 3 and the bed top 2. At this time, the rigid support force of the support rod 5 still protects the person inside. Assuming that the person is not in bed at this time, he can also climb in through the original entrance and exit. Figure 2A cross-sectional view of a pair of sawtooth hooks is drawn on the right. The fixed sawtooth hooks are fixed on the upper and lower edges of the vertical enclosure. The corresponding bed board and the bed top are connected to a sawtooth hook 11 on one side, and a sawtooth hook 11 with a spring is connected on the other side. When the bed is closed, the pair of hooks 11 are locked. When the sawtooth hook 11 with the recovery spring is moved in the opposite direction of the spring force, the two hooks 11 are disengaged. The energy-absorbing pad 4 on the bed board 1 or under the bed top 2 is not fixed to the bed, so that the volume of the protected person is minimized, and it is easier to reduce the force when it is hit into the corners.

[0015] Figure 3 yes Figure 1 The structural schematic diagram of the other two upper and lower components is applied. A straight rod is connected to each axis on the lower edge of the bed board 1 and the vertical enclosure 3, and the other ends of the corresponding two sections of the straight rod are connected together. There are four such connection forms distributed between the bed board 1 and the lower edge of the vertical enclosure 3. Two of them form a pair of "< >" shaped supports 9, which are fixed to the lower edge of the bed board 1 and the vertical enclosure 3 in the opposite axis to the other pair of "< >" shaped supports 9. A rope 7 is tied to the two horizontal diagonals of the "< >" shaped supports 9 to tighten. A straight rod is connected to each axis on the upper edge of the bed top 2 and the vertical enclosure 3. After the two straight rods cross, they are connected to an "X" shaped scissor support frame 10. Only one end of the straight rod constituting the scissor support frame 10 is connected to the edge of the bed top 2, and only one end of the remaining other straight rod is connected to the corresponding upper edge of the vertical enclosure 3. A rope 7 is tied to the horizontal side of the "X" shaped scissor support frame 10 to tighten. When an earthquake occurs, when bricks and stones fall down, the rope 7 of the "< >" shaped support 9 or the scissor-type support frame 10 will be severely impacted and broken, or the rope 7 on the limit rod of the earthquake warning action device will lose tension, so that the bed board 1, the bed top 2 and the vertical enclosure 3 are integrated. Figure 2 Similarly, there is also a serrated hook lock. Figure 3 The rotating shafts of the "< >" shaped support 9 and the scissor-type support frame 10 can be hidden in the edges of the bed board 1 and the bed top 2, so that the heights of the "< >" shaped support 9 and the scissor-type support frame 10 are zero.

[0016] Figure 4 yes Figure 1 A schematic diagram of the main structure constructed by using a simplified skeleton - scaffolding. For ease of observation and understanding, the scaffolding buckle 12 is marked with "·". Figure 4 A buckle is drawn in the lower right corner; secondly, only the scaffolding frame is drawn for the bed board 1 and the bed top 2, without laying wooden boards. The vertical enclosure 3 is built with scaffolding, and the left front gap of the vertical enclosure 3 is the entrance and exit for people to get on and off the bed. There are energy-absorbing pads 4 under the bed board 1 and above the bed top 2. A support rod 5 is fixed upward near the four corners of the edge of the bed board 1. The other end of the support rod 5 extends to the lower cylinder 6 fixed at the lower edge of the vertical enclosure 3. Figure 4In the figure, the lower cylinder 6 is replaced by a scaffolding buckle 12, and one scaffolding buckle 12 has two fixing screws, which respectively fix the cross-intersecting scaffoldings. When the screw of one of the scaffolding buckles 12 is fixed on the vertical enclosure 3, the screw of the remaining scaffolding buckle 12 is loosened until the nut does not fall off the screw. Such a scaffolding buckle 12 has a gap of more than 0.5 cm with the support rod 5 inside, so that when the vertical enclosure 3 falls, the friction surface between the support rod 5 and the scaffolding buckle 12 is small, and the fall is smooth. Similarly, the upper cylinder 8 is also replaced by a scaffolding buckle 12 with one end screw loosened. There is also a rope 7 on the scaffolding buckle 12 to limit the support rod 5. In order to prevent the amplitude of the longitudinal wave or transverse wave of the earthquake from being too large, causing the vertical enclosure 3 or the bed top 2 to be separated from the bed board 1, a number of iron wires 13 can be added to limit the vertical enclosure 3 or the bed top 2, and the iron wires 13 are at least two on each surface of the front, back, left and right.

[0017] The above are only three preferred embodiments of the present invention, which are 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.
