Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a bed apparatus, a sofa bed, or a bed device constructed by arranging plate-shaped members in the width direction of a frame formed in a rectangular frame shape. It relates to resting furniture such as chairs.

(Prior Art) For example, there are various types of bed devices,
As one of them, there is one in which a large number of plate-shaped bodies are installed along the width direction of a bed frame formed in a rectangular frame shape.

In the bed apparatus having such a structure, both ends of the plate-like body are supported by springs in order to improve cushioning properties.

However, when the user lies on the plate supported by the spring and the weight compresses the spring, the reaction force acts on the user, so that the user's body is strongly supported by the plate. It may be compressed and make you feel uncomfortable. In particular, a heavy part such as the buttocks of the user's body has a large degree of compressing the spring, so that the reaction force thereof becomes large and the feeling of pressure becomes strong.

Further, the spring supporting the plate-like body inevitably vibrates at a high frequency when a load is applied, and it takes a considerable time for the vibration to be attenuated. Therefore, if the load applied to the plate-shaped body changes when the user rolls over, the high-frequency vibration of the spring supporting the plate-shaped body continues for a long time, which also reduces the comfort of sleeping. There was also a thing to do.

BACKGROUND ART A water bed in which water is enclosed in a mattress is known as a bed device that supports a user along a body shape and distributes body pressure evenly to contribute to good sleeping comfort.

However, since the water bed requires a large amount of water, there is concern that the mattress will be damaged,
Further, since the body is in close contact with the mattress, the breathability is poor, and the water in the mattress moves like a wave, which may give the user discomfort similar to seasickness.

(Problem to be Solved by the Invention) As described above, according to the conventional bed apparatus in which the plate-shaped body is supported by the spring along the width direction of the bed frame, the reaction force of the spring compressed by the load is applied to the user. ,
Since the high-frequency vibration of the spring continues for a long time due to the change in the load applied to the plate-shaped body, it has been the case that the sleep comfort is deteriorated by these factors. Further, according to the water bed, there is a case where a large amount of water is used, and moreover, the water moves like a wave in the mattress, which gives the user discomfort similar to seasickness.

The present invention has been made in view of the above circumstances, and an object thereof is that even if a plate-shaped body receives a load, its reaction force is hard to act on a user, and the received load varies. Even if the above-mentioned plate-like body is supported so as not to vibrate, a comfortable furniture can be obtained without using a large amount of water such as a water bed.

[Structure of the Invention] (Means and Actions for Solving the Problems) In order to solve the above problems, the present invention is directed to a frame, a hollow-shaped member for containing a fluid therein, and both sides of the frame. Elastic support members provided at predetermined intervals, plate-like members provided with their end portions supported on upper portions of a pair of elastic support members corresponding to each other in the width direction of the frame, and inside each elastic support member. A communicating portion that is provided in communication and that allows a fluid that flows out from a compressed elastic support body to flow into another elastic support body, and a resistance that the fluid inside the elastic support body that flows out of each elastic support body flows out Flow rate control means set to be larger than the resistance.

With such a configuration, the fluid is caused to flow out from the elastic support body that receives a large load, and the fluid flows into the elastic support body that receives a small load through the communication portion, thereby reducing the reaction force applied to the user, Further, the fluid flows and receives a load, so that the frequency of vibration is smaller than that in the case of using a coil spring, the vibration is attenuated in a short time, and the amount of fluid used can be reduced.

(Embodiment) An embodiment of the present invention will be described below with reference to FIGS. 1 to 5. FIG. 4 and FIG. 5 show a bed apparatus as resting furniture, which bed apparatus comprises a bed frame 1.

A mounting port body 11 is fitted to an end portion of the guide body 9 protruding from the through hole portion 7a. A nozzle body 12 is integrally provided in the mounting opening body 11, and the nozzle body 12 is fitted into a mounting hole 13 formed in one side of the angle member 2 of the bed frame 1. One end of a connecting end tube 14 is connected to the tip of the nozzle body 12 protruding from the mounting hole 13. The other end of the connection end pipe 14 is connected to a communication pipe 15 forming a communication part. The communication pipes 15 are provided along both sides of the bed frame 1, respectively. One end of each communication pipe 15 is closed, and the other end is the first and second pumps 16 and 1 provided below the frame 1 on the headboard 3 side as shown in FIG.
7 are connected respectively.

The guide body 9 has a large diameter portion 9a on the lower side and a small diameter portion 9b on the upper side. A plurality of communication holes 18 are formed in the peripheral wall of the large-diameter portion 9a, a lower end of the small-diameter portion 9b is closed, and a lower end of a tubular slider 19 having an open upper end is slidably inserted. This slider 1
The upper end side of 9 is liquid-tightly fitted into the through hole 8a of the upper cap 8 and is fixed by the band 19a. A mounting member 21 is provided at the open end protruding from the through hole 8a. In this mounting member 21, a base portion 22 fitted and fixed to the upper end portion of the slider 19 and a hollow storage portion 24 provided on the base portion 22 via a shaft portion 23 are integrally made of a relatively soft synthetic resin. It is molded.

A pair of corresponding mounting members 2 on both sides of the frame 1
As shown in FIG. 3, both ends of a narrow first plate-like body 25 that is convexly curved upward are inserted into and supported by the first storage portion 24. Two waving bands 26 are provided on the upper surface side and the lower surface side of both ends of the first plate-shaped body 25, respectively, over the entire length in the longitudinal direction of the bed frame 1. A second plate-shaped body 27 is provided between a pair of adjacent first plate-shaped bodies 25. Each end of these second plate-like bodies 27 is sandwiched by two waving bands 26 as shown in FIG. That is, in the second plate-shaped body 27, one waving band 26 located on the upper surface side of the first plate-shaped body 25 is bonded to the lower surface side, and the other waving band 26 located on the lower surface side is bonded to the upper surface side. It is sandwiched by joining. Further, the second plate-shaped body 27 and each waving band 26 are fixed by a screw 28 to prevent the second plate-shaped body 25 from falling off.

A fluid L as a liquid is supplied to the elastic support 5 on one side in the width direction of the bed frame 1 by a first pump 16 via one communication pipe 15. Further, the liquid L is supplied to the elastic support 5 provided on the other side of the bed frame 1 by the second pump 17 via the other communication pipe 15. The liquid L is supplied to each elastic support 5 in a state where they are not fully extended. That is, when the liquid L is supplied to each elastic support 5, H _{1 in} FIG.
It is in a state where it can be extended from the height indicated by to the height indicated by H ₂ .

The nozzle body 1 is attached to the mounting body 11 at the lower end of the elastic support body 5.
The flow control valve 29 is provided in a state in which a part of the opening 2 is closed. The flow control valve 29 is made of a plate-shaped member that can bend only in the upward direction, and controls the amount of the liquid L in the bellows 6 flowing from the communication hole 18 to the communication pipe 15 when the elastic support 5 is compressed. It is regulated so that it hardly resists the flow in the opposite direction.

First and second plate-like bodies 2 installed on the bed frame 1
As shown in FIG. 4, the user U lies on his back on the sheets 5 and 27 through a thin sheet-like cushion material (not shown). A balance mechanism 31 shown in FIG. 3 is attached to each of the first plate-like members 25 at positions substantially corresponding to the back portion s and the buttocks portion d of the user U. The balance mechanism 31 includes a first lever 33 and a second lever 34 each having a long hole 32 at one end.
Have and. One ends of these levers 33 and 34 are slidably pivotally attached to the first pin 35 through the elongated holes 32, and the other ends are fixed to the lower surfaces of both ends of the first plate 25. The brackets 36 are pivotally attached by the second pins 37 via the long holes 34a. Also,
The middle portion of each plate 25 is pivotally attached to the second bracket 38 by a third pin 39. The second bracket 38 is erected on a lateral member 41 that is erected in the width direction of the bed frame 1.

In this way, if the balance mechanism 31 is provided on the first plate-shaped member 25, for example, when a load is applied to one end side of the first plate-shaped member 25 as shown by A in FIG. Plate 25
The other end of the first lever 33 connected to the third pin 3
It is pivotally displaced in the downward direction indicated by arrow x with 9 as a fulcrum. The rotation of the first lever 33 causes the second lever 34 to rotate in the arrow y direction. As a result, the other end of the second lever 34 pivotally attached to the first plate 25 is also displaced in the descending direction. That is, even if a load is applied only to one end side of the first plate-shaped body 25, both ends are displaced downward by substantially the same amount. Therefore, the first plate-shaped body 25 is moved in the width direction of the bed frame 1. It is possible to prevent it from being inclined and displaced.

In the bed apparatus configured as described above, when the user U lies on the first and second plate-like members 25 and 27 as shown in FIG. 4, heaviness such as the back s and the buttocks d of the user U is heavy. The part corresponding to the part receives a larger load than the other parts. The first plate-like body 2 in the portion that receives a large load
In the elastic support body 5 supporting both ends of the bellows 5, the slider 19 housed inside the bellows 6 is guided by the guide body 9 and slides downward, whereby the bellows 6 is compressed.

In this way, when the bellows 6 is compressed, the liquid L contained therein flows out through the nozzle body 12 and the connecting end pipe 14 to the communication pipe 15. Then, the liquid L flowing out to the communication pipe 15 is a bellows 6 of the elastic support 5 such as both ends in the longitudinal direction of the bed frame 1 which is an elastic support 5 that does not receive a large load and a portion corresponding to the leg of the user U. Flow into the inside and extend the bellows 6 of these elastic supports 5 to
The load applied to the plate-shaped body 25 is absorbed.

That is, the elastic support body 5 that receives a large load can transfer the liquid L contained in the bellows 6 to the other elastic support body 5.
The load is elastically absorbed by flowing into the bellows 6. At this time, even if the elastic support body 5 is compressed under a large load, it does not generate a reaction force corresponding thereto, so that the user U strongly presses a heavy portion such as the buttocks d and the back s. Is prevented.

The elastic support 5 that expands and contracts due to the flow of the liquid L is
Since the liquid L is incompressible and flows against the flow resistance, the liquid L expands and contracts gently and is not accompanied by vibration of high frequency unlike the coil spring. Therefore, the user U rarely feels uncomfortable due to the vibration.

Further, the flow rate regulating valve 29 provided on the nozzle body 12 of the elastic support body 5 makes the outflow resistance of the fluid L from the bellows 6 larger than the inflow resistance. Therefore, the elastic support 5 supporting the heavy part of the body of the user U slows down the outflow of the liquid L from the bellows 6, and prevents the heavy part of the user U from dropping suddenly. In addition, since the liquid L quickly flows into the elastic support body 5 that does not receive a large load, the elastic support body 5 corresponding to, for example, the leg portion, which is a light portion of the human body, expands quickly to ensure that portion. I will support you.

Further, since the elastic supports 5 provided on one side and the other side in the width direction of the bed frame 1 are connected to the different communication pipes 15, respectively, the elastic supports 5 on both sides can be made independent of each other. That is, when a large load is applied to one side in the width direction of the bed frame 1, the liquid L on the one side is applied.
Does not flow to the other side, which prevents large downward displacement of one side, and
A large upward displacement of the other side is also prevented. Further, the first pump 1 is connected to the pair of communication pipes 15.
Since the liquid L can be separately supplied and discharged by the 6 and the second pump 17, the left and right elastic supports are supported by the amount of the liquid L stored in the elastic supports 5 on both the left and right sides of the bed frame 1. The cushioning property of the body 5 can be adjusted.

Further, the mounting member 21 supporting the end portion of the first plate-shaped body 25
The storage portion 24 elastically deforms the shaft portion 23 and is tiltable in the width direction. Therefore, the first plate 25
Tilts according to the curved state of the back surface of the user U, which also improves the sleeping comfort. Since the second plate-shaped body 27 supported by the waving band 26 is also tiltable in the width direction, the second plate-shaped body 27 does not impair comfort.

Further, a guide body 9 made of a hard material and a slider 19 slidably inserted in the guide body 9 are provided in the bellows 6 of the elastic support body 5. Therefore, the guide body 9 and the slider 19 prevent the bellows 6 from swaying in the lateral direction, which is a direction intersecting the axial direction, so that the first plate-shaped body 25 does not sway.

In addition, a plurality of first plate-like bodies 25 provided at predetermined locations
Since the balance mechanism 31 is provided in the first plate-shaped body 25, the first plate-shaped body 25 has substantially the same displacement amount on the one end side and the other end side. Therefore, even if the user U lies on one side of the bed frame 1 in the width direction, the one end side is not displaced lower than the other end side, and the supporting state of the user U does not become unstable.

Further, since the amount of liquid used in this bed apparatus need only be accommodated in the elastic support 5 and the communication pipe 15, the amount of liquid used is greatly reduced as compared with the conventional water bed. Moreover, unlike the water bed, shaking does not occur due to the flow of the liquid, so that a comfortable sleeping comfort can be obtained.

6 and 7 show another embodiment of the present invention. In this embodiment, the elastic support 5 is a closed bellows 6a,
The guide body 9 and the slider 19 are not provided inside the bellows 6a unlike the above-described embodiment.

On the other hand, the bed frame 1 is formed by the square tube member 1a, and the internal space of the square tube member 1a serves as the communication portion 41. The bellows 6a is provided with the lower end surface joined and fixed to the upper surface of the rectangular tubular member 1a, and the connection end pipe 1
The inner space of the bellows 6a and the communicating portion 41 are communicated with each other by 4a.

The connecting end pipe 14a is used which is sufficiently thinner than the diameter of the bellows 6a. Therefore, the connection end tube 1
4a has a great resistance when the bellows 6a is compressed and the fluid inside the bellows 6a flows out to the communicating portion 41, so that the bellows 6a is prevented from being rapidly compressed.

A storage member 42 is fixed to the upper end surface of the bellows 6a, and the end portion of the first plate-shaped body 25 is inserted and supported in the storage member 42.

Even with such a configuration, the same operational effect as that of the above-described embodiment can be obtained.

Further, the resting furniture is not limited to the bed device, and may be a sofa bed or a chair.

[Effects of the Invention] As described above, according to the present invention, a reaction force corresponding to the load is not generated in the elastic support body that receives a load, unlike a coil spring. The heavy part is not pressed. Moreover, since the liquid contained in the elastic support receives the load due to the flow, it is gently deformed without vibrating at a high frequency like a coil spring. To be Further, the amount of liquid used is smaller than that in the conventional water bed, and the liquid does not flow like a wave and shake. Further, the resistance of fluid outflow to each elastic support is set to be larger than the resistance of fluid inflow. Therefore, the outflow rate of the fluid from the elastic supporter supporting the heavy portion of the user becomes slow, so that the heavy portion of the user can be prevented from dropping suddenly.
