Description

Description book multi-bed technology

The utility model relates to a bed in the field of furniture, in particular to a multi-purpose bed.

Background technique

The beds and writing desks that are currently mass-produced and sold on the market are separated independently, not only because they have their own uses, but also because of their different external structural dimensions. For example, the height of an ordinary writing desk is 75 to 78 cm, and the height of the bed is generally in the range of 40 to 55 cm. One third of the time a person needs to rest in bed, and the quality and function of the bed is directly related to the quality of sleep rest.

In the known patent-pending technology, the bulletin number CN1265751C is entitled "a multifunctional crib", and the publication number CN1256058C is entitled "Improvement of bed and desk combination furniture" and other patents have improved the single function of the bed. . The latter patent is an improvement on the wall bed, which is more complicated in structure and higher in production cost.

In addition, soft mattresses, sofa cushions and various cushions currently on the market are mostly made of springs and sponges, with a single function and no heat-dissipating effect. Water mattresses produced according to the known art have the disadvantages of large overall sway, stun sensation, and high production cost, and the cost of producing mattresses for sloshing is further increased.

So far, the combination of the bed and the writing desk has not been found to have the following characteristics: 1. At the same time, the functions of the bed and the writing desk are retained, and the conversion between each other is convenient. 2, the bed should not only have a comfortable and warm effect, but also should have the function of cooling in the summer, changing the single function of the writing desk. 3. Simple structure, convenient operation and low production cost, suitable for ordinary consumers. Secondly, it has not been found that the bed can be used as a sofa and has a double function multi-purpose bed that is filled with water and inflated.

Summary of the invention

It is an object of the present invention to provide a multi-purpose bed having the dual function of a bed and a table.

In order to achieve the purpose of J1, a single multi-purpose bed made of steel material or wood material as the main material is designed as shown in Fig. 1, Fig. 2, Fig. 3 in the drawings of the specification. The composition of the multi-bed includes: two reversible work boards (1), four hinges (2), one bed (3), one storage box (4), an item for storing computer equipment Shelf (5), two movable rectangular stools (6), two stretchable skateboards ( ⁷ ) with computer keyboards and simple items, and a set of multi-purpose mats (8) - water mattresses or air mattresses Synthetic bed. The connection relationship and combination status of each component are: The reversible work board (1) is connected to the bed body (3) through the hinge shaft (2) and placed in the storage box. (4) and the item placement frame (5) form a combination of bed and table. Two movable rectangular stools (6) are placed adjacent to each other on the length side of the multi-bed, and the stretchable skateboard (7) can be stretched in the bed. On both sides of the body (3), a combined multi-purpose mat (8) is placed in the bed body (3), and the multi-purpose mat (8) is made of two or more polyethylene plastic bobbins, filled with water or air. The composite bag formed by combining the two ends of the tubular bag which is heat-sealed at both ends is connected with two to six continuous long-length cloth tapes having the same diameter as the cylindrical bag between each of the independent cylindrical bags which are flushed into the air. The bed is fastened with a long cloth around the combined air mattress, and the work board (1) is turned from the upright state to the horizontal state, and the bed-to-table conversion is completed.

In order to ensure the required strength requirements for use ^: to avoid the trouble caused by the inadvertent breakage of the water mattress, the designed bed basin (3) should meet the above requirements. 5 毫米的冷轧 The thickness of the bottom of the bed is 0. 7~1. 5mm cold rolling Or the hot-rolled iron plate and the frame are welded to form a non-leakage whole body. In order to increase the strength of the bottom of the bed body (3), a flat iron with a welding width of 50 mm and a thickness of 5 is added at the bottom.

A combined multi-purpose mat (8) is placed in the bed body (3), and the multi-purpose mat (8) is made of two or more polyethylene plastic bobbins, filled with water or air, and heat-sealed at both ends thereof. In order to make the multi-purpose mat (8) achieve the purpose of low production cost and good use effect, the theoretical analysis and test of the multi-purpose mat (8) proposed the technical solution to solve the problem as follows:

A. The thickness of the water bag made of the material is 0. 18mm. The thickness of the water bag made of the material is 0. 18mm. After being filled into the water seal, it can withstand the pressure of 150kg without damage and leakage. When the thickness of the plastic bag is increased to 0.36mm, it can meet the requirements of daily life. Increasing the thickness to more than 0.5 mm will cause unnecessary waste and affect heat exchange. ·

B. The inner diameter of the water bag is Φ80~Φ350, and the length is 900mm. For the comparison test, the minimum diameter is Φ 80瞧 and the length is 900mm. For example, it can only be loaded with 4.16kg water. If the diameter is less than Φ80, wake up. When the temperature of a single water bag is easy to rise, and the temperature does not rise, it cannot circulate with other water bags; but if the diameter reaches Φ 350πιπι and the length is 900匪, the water bag has a flat height of 80 hidden, and the width is 500 countries. 36kg water, if the length of the water bag is increased to 2200mm, the water capacity in the water bag will continue to increase, and the single water bag will not be easily moved after being filled into the water, and because of its large area, the area affected by the shaking is also large. The water bag with a domestic diameter of 114. 6~0 127. 4 can hold water 7. 8kg~10kg when the length is 900mm, the height of the water bag is 80 hidden, and the pillow and seat cushion are made of 2~3 plastics. The composition of the tubular bag can be combined. It takes 13 to 15 water bags to combine a single bed, which can be applied to the climate in Tianjin and Beijing. The diameter of the water bag used in the high temperature area in the south should be appropriately increased on this basis, and the height of the water bag should be increased to achieve the effect of increasing heat exchange. As it is broken down into dozens of independent water bags, Therefore, when each water bag is stressed, it will not affect the water bag at other locations, which solves the phenomenon that the traditional water bed is affected by the force. As shown in the drawings of the specification, a continuous loop strip of the same diameter as the plastic bobbin is connected between each of the independent water bags. Tightening with a long cloth around the combined water bag can further reduce the shaking of the water bag.

C The combination of water bags, each part of each water bag is evenly stressed and not easily damaged. After the water is filled, the air should be drained as much as possible, and then sealed with a heat sealing machine. The outer cover bag made of chemical fiber fabric or pure cotton or blended fabric of the same size on the polyethylene plastic tubular bag outer jacket can further improve the compressive strength.

D. Change the water filled in the water bag to air to become an air cushion.

The air mattress (9) is made of 2~6 pieces of polyethylene plastic cheese cloth or fabric and chemical fiber fabric of the same diameter. An air mattress with an endless belt connecting each individual tubular air bag, and a cylindrical air bag made of polyethylene plastic and covered with a cloth outer cover bag around the air mattress (9) 11) surrounding, the four corners are connected by a rope; a back frame (13) of a rectangular frame structure is arranged on the side of the multi-bed length, and a sleeve (14) is welded at the lower end of the back plate (13), Drill the casing (14) and splicing the nut on the hole, screwing the screw (15) into the fastening, tightening the screw (1 can adjust the twist of the back plate (13), and the back plate (13) a wide tape (16) made of thick fabric with a strap, and a cylinder made of a polyethylene plastic bag with two cloth outer pockets placed on top of the air mattress (9) The air bag forms a multi-bed that can double as a sofa. The up and down position of the water mattress (8) and the air mattress (9) is converted into a multi-water bed. Figure 7 to Figure 9 in the drawings of the specification. The height of the top surface of the single bed basin (3) is 36~40cm, and two diameters of 450 hidden length 2060mm and diameter of 330mm are placed on the air mattress (9) or the water mattress ( ⁸ ). For 2060, a cylindrical air bag (12) made of a polyethylene plastic tubular bag constitutes a multi-bed that can double as a sofa. When the outer bag is not covered, two independent cylindrical air bags (the weight of 13 are respectively 360 grams and 490 grams, easy to move.

The utility model has the advantages that the multi-purpose bed with the double function of the bed and the table skillfully combines the bed and the table, and the multi-purpose bed which can be used as the sofa is designed with reasonable structure, firmness and durability, occupying small room area and weight. Light, even the bed basin (3) with all-steel structure is only 30 kilograms. It is easy to use and has low manufacturing cost and is suitable for ordinary consumers. The advantage of the multi-purpose mat is that the cost is low. To make a water pillow or a small sofa cushion, it only needs 100~170g of poly.ethylene material. The current market price of raw materials is 2. 00~3. 20 yuan, and the production of a set of long 2000, hidden, wide 900 hidden, high 80 hidden size single water mattress, when using a polyethylene plastic cheese cloth of 0.36mm thickness, the required raw material cost is 29.90 yuan. 2The combination mat has small overall shaking and good use effect.
