[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a sleeping mattress to be laid on a floor such as a tatami mat or a board.

[0002]

[Prior art]

 Conventionally, reclining mechanisms that can freely adjust the angle of the backrest have been widely used for beds and seats. For example, the reclining mechanism provided in a chair or the like is often a manual structure using a ratchet bracket. Beds used in hospitals and the like use an electric reclining mechanism that does not burden patients.

[0003] In general, such a reclining mechanism in a bed is connected to a bed frame or a leg, and a mat member is fixed to the reclining mechanism. When such a bed is used, a mattress or the like is usually laid on a mat member, and the backrest is raised or lowered at a comfortable angle manually or by an electric means.

[0004]

[Problems to be solved by the invention]

 However, in the chair provided with the reclining mechanism described above, since it is impossible to hold the head and the feet, there is a problem that the user feels fatigue when used for a long time. Also, adjusting the backrest manually places a heavy burden on the elderly and children, especially when the angle of the backrest is made obtuse, remove the body from the backrest once and unlock the ratchet bracket to unlock the back. It was necessary to perform the troublesome operation of adjusting the angle again after returning the back to a horizontal state.

On the other hand, a bed having a built-in manual or electric reclining mechanism has a bed frame, legs, a mat member, and the like, so that it becomes considerably larger than a general bed. Many problems have occurred in terms of transportation, storage, manufacturing costs, and the like. Further, since the bed usually has a certain height, there is a possibility that an injury such as a fracture or a bruise may occur if the bed falls during bedtime.

[0006] Therefore, an object of the present invention is to solve the above-mentioned problems, to raise and lower the backrest with a simple operation, to facilitate movement and storage, and to realize a safe usability. Is to provide stress.

[0007]

[Means for Solving the Problems]

 In order to achieve the above object, the mattress of the present invention is characterized in that a sleeping mattress used to be laid on a floor surface is provided with a reclining mechanism.

[0008] A sleeping mattress that is directly laid on a floor such as a tatami mat or a wooden board and the like has a built-in reclining mechanism for raising and lowering a backrest, thereby providing a comfortable feeling of use and a large-scale device. This eliminates the need for storage, is excellent in terms of movement and storage, and also prevents a fall accident that occurs while sleeping.

In the present invention, the reclining mechanism is connected to a gas pressure cylinder, a first frame holding one end of the gas pressure cylinder, and the other end of the gas pressure cylinder. And a connecting member interposed between the first frame and the second frame.

[0010] Since the reclining mechanism has a system that raises and lowers the frame using a gas pressure cylinder, smooth operation is realized, and even an elderly person or a child without physical strength can easily operate. be able to.

Further, more preferably, the gas pressure cylinder is provided on both sides of a reclining mechanism.

By providing the gas pressure cylinders on both sides of the reclining mechanism, the reclining undulation strength can be increased.

[0013]

[Embodiment of the invention]

 Hereinafter, an embodiment of the reclining type mattress of the present invention will be described with reference to FIGS. 1 to 5.

FIG. 1 shows an example of the mattress of the present invention. 2 and 3 show a preferred configuration example of the reclining mechanism built in the mattress of the present invention. As shown in FIGS. 1 and 2, the mattress body 1 is a sleeping mattress that is used by directly laying it on a tatami or board floor, and includes a reclining mechanism 2 using a gas pressure cylinder 9. I have.

As shown in FIGS. 2 and 3, the reclining mechanism 2 includes a gas pressure cylinder 9, a first frame 10 holding one end 4 of the gas pressure cylinder 9, and a gas pressure cylinder 9. The second frame 20 is connected to the other end 5 of the first frame 10 and is undulated by the contraction of the gas pressure cylinder 9, and the connecting member 3 is interposed between the first frame 10 and the second frame 20. ing. The periphery of the reclining mechanism 2 is covered with a cover 30 formed of urethane or the like.

The first frame 10 has a U-shape. An arm 11 for fixing one end 4 of the gas pressure cylinder 9 is provided substantially in the center, and a connecting frame 13 for reinforcement is provided in the opening 12. Is fixed.

On the other hand, the second frame 20 also has a U-shape, and a flat arm 22 is laid across the opening 21, and the side of the arm 22 is provided with a gas cylinder 9. A holding member 23 for rotatably holding the other end 5 is provided. The first frame 10 and the second frame 20 are connected by a connecting member 3 so as to be freely bent as shown in the figure.

Since the gas pressure cylinder 9 has a lower spring constant than a coil spring, it has a feature that a substantially constant spring force is generated over a long compression stroke. Therefore, the smooth operation is realized, and at the same time, the second frame 20 can be raised and lowered while the user is resting on the second frame 20 (backrest).

One end 4 of the gas pressure cylinder 9 is fixed to a U-shaped fixing member 14 installed on the arm 11, and the other end 5 is fixed to a side surface of the arm 22. Is rotatably connected to the holding member 23. A switch 7 is provided at one end 4 of the gas pressure cylinder 9, and when the handle 6 is moved, the switch 7 is pressed, the piston 8 of the gas pressure cylinder 9 is extended, and the second frame 20 is moved. It can be inclined at an appropriate angle.

The reclining mechanism 2 according to the present invention is preferably provided with a gas pressure cylinder 9 ′ at a position symmetrical to the gas pressure cylinder 9. By providing the gas pressure cylinder 9 ', the undulating strength in reclining can be increased.

Further, the periphery of the first frame 10 and the second frame 20 is covered with a cover 30 made of urethane or the like. It is preferable to provide a corrugated uneven portion 31 having an air permeability and an acupoint stimulation effect on the upper surface of the cover body 30. Further, in the mattress of the present invention, the end portion 32 of the cover body 30 is detachably formed, so that it can be stored compactly.

The undulating system in the reclining mechanism 2 is not particularly limited to a gas pressure cylinder, but may be a reclining mechanism using a hydraulic cylinder or an electric motor.

Next, a method of using the reclining mattress of the present invention will be described. First, the user lays the mattress body 1 held in a horizontal state directly on a floor such as a tatami mat or a wooden board, and lays on the back on the back. When the switch 6 of the gas pressure cylinder 9 is pressed by pulling the handle 6 toward the user, the piston 8 having a repulsive force in the extension direction pushes the arm 22 and the second frame 20 (backrest) is moved to an arbitrary angle. Tilt it. When the switch 6 is released by the handle 6 after the inclination, the piston 8 is prevented from returning to its original position by the pressure in the gas pressure cylinder 9, and the second frame 20 is held in the inclined state. (See FIG. 4).

When returning the mattress body 1 to the horizontal state, the handle 6 is pulled toward the user, the switch 7 of the gas pressure cylinder 9 is pressed, the locked state of the piston 8 is released, and the weight of the upper body is reduced. To the second frame 20, it is possible to return to the original horizontal state.

As shown in FIG. 5, as a preferable example of the method of using the mattress of the present invention, a mattress 34 is laid on the mattress body 1 and the second frame 20 (backrest) is inclined to an arbitrary angle. After that, by arranging the movable table 33 or the like on the mattress main body 1, reading and eating can be performed in a more comfortable state.
