[0002]

2. Description of the Related Art In general, a bed apparatus is used for a user to go to bed. To increase the added value of the bed apparatus, various functions have been considered.
In particular, in recent years, hospitals have been demanding the development of a bed device having a function of giving exercise while sleeping in order to recover the physical strength of a sick person. There is also a demand for the development of a bed device that can prevent a user who cannot turn over with the floor from getting stuck.

[0003] If exercise can be given to the body of the user, the blood circulation of the body will be improved, and maintenance and recovery of health can be measured. In addition, if exercise can be given to bedridden elderly people and patients, it can be useful for recovery of function, furthermore, falling asleep (when giving the user shaking that seems to be comfortable), awakening ( It can be used for stimuli.

[0004] In addition, if the user's body is swung right and left, the user can perform a rollover exercise. Thus, in the case of a sick person or an elderly person who has been lying on the bed for a long period of time, it is possible to prevent pressure ulcers by performing the rolling motion at a gentle speed.

[0005] Therefore, there is a demand for the development of a bed device having a function of giving such exercise to a user. However, conventionally, a device capable of giving the above-described exercise to a user lying on the bed device has not been developed. Therefore, development of a bed device having such a function has been desired.

[0006]

As described above, in a conventional bed apparatus, particularly in a bed apparatus for a hospital, exercise is performed on the user in order to recover the health of the user who lies on the back and to prevent the bed from being stuck. The development of a bed device that can be provided has been desired.

[0007] This invention is based on the above circumstances, and the purpose is not only to go to bed but also to give exercise to the user to measure the maintenance and recovery of health. The purpose of the present invention is to provide an improved bed device.

Embodiments of the present invention will be described below with reference to the drawings. FIGS. 1 to 7 show an embodiment of the present invention. The bed apparatus shown in FIG. 1 includes a bed frame 1 formed in a rectangular frame shape by a pair of side plates 2 and end plates 3. In the bed frame 1, a base member 4 formed in a rectangular frame shape smaller than the bed frame 1 is arranged as shown in FIGS. This base member 4
The bed frame 1 is connected to the bed frame 1 by a pair of joint bars 5 provided along the width direction of the bed frame 1. That is, the joint bar 5 is formed by bending the band-like material into an inverted trapezoidal shape, and both ends thereof are connected and fixed to the crosspiece 6 provided on the inner surfaces of the pair of side plates 2.
An intermediate portion is connected to the base member 4.

At the four corners of the base member 4, four elongated rectangular supporting columns 7 are provided upright along the width direction of the bed frame 1. A pair of connecting members 8 are provided at the upper end of each support column 7 along the longitudinal direction, respectively. As shown in FIG. 4, the connecting member 8 has an elastic member 8a formed in a columnar shape by rubber or the like, and a pair of bolts having heads embedded at both ends of the elastic member 8a and having screw portions projecting from the respective end surfaces. 8b, and one bolt 8b is fixed to the upper surface of the support column 7 by a nut 9.

The other bolt 8b of the connecting member 8 has
Each of the elongated rectangular plate-shaped divided pieces 11 is fixed at its midpoint in the longitudinal direction by a nut 9. Thus, each of the divided pieces 11 is swingably connected to the support column 7 with a portion connected to the connection member 8 as a fulcrum.

The swingable four divided pieces 11 are arranged in two rows and two columns in the width direction and the longitudinal direction of the bed frame 1 to form a floor plate 13. On this floor plate 13, FIG.
The mattress M is placed as shown by a dashed line in FIG.

[0014] As shown in FIG.
One end of a connecting member 14 having the same configuration as the connecting member 8 is fixed to the lower surface of the central portion in the width direction of the adjacent end of each pair of divided pieces 11 along the longitudinal direction of the memory 1. The other end of the connecting member 14 is fixed to the connecting member 15.

Accordingly, the pair of divided pieces 11 connected in the longitudinal direction (row direction) by the connecting members 15 can be displaced in the vertical direction so that the supporting members 7 are elastically deformed while the connecting members 14 are elastically deformed. In addition, it swings around a point supported by the connecting member 8 as a fulcrum.

As shown in FIGS. 5 and 6, the connecting member 15 is connected and fixed to the upper end of a movable arm 16 as a power transmitting means by a bolt 17. The lower end of the movable arm 16 is connected to a turntable 18. That is,
A long hole 19 is formed in the turntable 18. This slot 1
7 is set so that the radius from the center O of the rotating disk 18 at any point from one end A to the other end B becomes larger as shown in FIG.

A bolt 21 is inserted into the elongated hole 19 from one side surface of the turntable 18. A stepped bush 22 is fitted into a portion of the bolt 21 protruding from the other side surface of the turntable 18. The movable arm 16 is rotatably fitted into a small diameter portion of the bush 22 through a mounting hole 16a formed at the lower end thereof.

A nut 23 is screwed to an end of the bolt 21 protruding from the bush 22 via a washer 24, whereby the movable arm 16 is connected to the bush 22.
Is prevented from falling off. That is, the lower end of the movable arm 16 is rotatably connected to the elongated hole 19 located at the eccentric position of the turntable 18, and the amount of eccentricity fixes the bush 22 to any position of the elongated hole 19. It can be set depending on whether or not.

One end of a drive shaft 25 is connected and fixed to the center of the pair of left and right rotating discs 18, respectively. As shown in FIG. 3, an intermediate portion of each drive shaft 25 is rotatably supported by a bearing 26, and the other end is a pair of a two-axis motor 27 disposed at the center of the base member 4. Are coupled to each other via a coupling 29.

When the two-axis motor 27 operates to rotate the pair of output shafts 28, the rotation is transmitted to the turntable 18 via the drive shaft 25. When the turntable 18 is rotated, the movable arm 16 whose lower end is connected to the eccentric position of the turntable 18 and whose upper end is connected to the pair of divided pieces 11 via the connecting member 15 and the connecting member 14 drives the movable arm 16 up and down. Is done. Thereby, the pair of divided pieces 11 connected to the connecting tool 15 swings about the portion connected to the support column 7 by the connecting member 8 as a fulcrum.

The coupling 29 can set the connecting angle of the drive shaft 25 and the output shaft 28 in the rotational direction to a predetermined angle. Thereby, since the angle of the rotation direction of the pair of left and right rotating disks 18 can be set, it is possible to change the rocking state of the pair of left and right divided pieces 11 that are rocked by the rotation of the respective rotating disks 18, that is, change the phase. I can do it.

According to the bed apparatus having such a configuration, the two-axis motor 27 can be used while the user is lying on the mattress M.
When the pair of output shafts 28 are driven to rotate, the rotation is transmitted to the pair of rotary disks 18 via the drive shafts 25, so that the movable arm having the lower end connected to the eccentric position of each rotary disk 18. The arm 16 moves up and down according to the amount of eccentricity.

When the movable arm 16 is driven up and down, each pair of divided pieces 11 whose one end is connected to a connecting member 15 provided at the upper end thereof via a connecting member 14 is connected to the supporting column 7 by a connecting member. It swings around the middle part connected by 8 as a fulcrum.

If the pair of left and right divided pieces 11 is swung, for example, in the same phase, as shown by a chain line in the figure, the central portion in the longitudinal direction of the mattress M is bent up and down. Since the waist of the user is repeatedly bent, exercise can be given to the waist of the user.

The vertical movement of the movable arm 16
Is changed by the amount of eccentricity with respect to the turntable 18,
The amount of eccentricity loosens nut 23 and bolt 21
8 along the long hole 19 and tighten the nut 23 at an arbitrary position to fix the bush 22.
Can be variable.

If the stroke of the up and down movement of the movable arm 16 is adjusted, the amplitude of the swing of each pair of divided pieces 11 changes, so that the amount of exercise given to the user lying on the mattress M can be changed. Can be. For example, if the amount of eccentricity of the movable arm 16 connected to the turntable 18 is increased and the stroke of the vertical movement of the movable arm 16 is increased, the swing of the pair of divided pieces 11 can be increased. Since the amplitude also increases, the amount of exercise given to the user can be increased.

As described above, if the amount of exercise given to the user can be changed, the user can exercise according to the physical condition. For example, in the early stage of the recovery of the user's condition, exercise by reducing the amplitude of the divided piece 11 can prevent excessive exercise, and the swing of the divided piece 11 can be prevented depending on the degree of recovery. By gradually increasing the amplitude, recovery of physical strength can be easily measured.

The movable arm 16 not only moves up and down due to the rotation of the turntable 18 but also moves at its lower end in accordance with the amount of eccentricity of the turntable 18 from the center of rotation. The stress generated by the rotational movement is caused by the connecting member 1 made of an elastic material connecting the divided piece 11 to the movable arm 16.
4 absorbs by elastically deforming. Therefore, divided piece 1
1 is prevented from being subjected to a large stress due to the rotational movement of the movable arm 16.

On the other hand, a pair of left and right split pieces 1 is provided by a coupling 29 connecting the output shaft 28 and the drive shaft 25.
By changing the phase of the swing of one, the user on the mattress M is twisted in the lateral direction while the body is bent from the central portion. The magnitude of the twist at that time is proportional to the phase shift.

The movement in which the user's body is twisted in the left-right direction while being bent is, for example, the swinging of the pair of split pieces 11 in the right row with respect to the swing of the pair of split pieces 11 in the left row. Following by the phase difference, a torsional motion is given when each pair of the divided pieces 11 reversely intersect at the bottom of the valley and the top of the peak.
That is, the user's body can be swung right and left.

By shaking the user's body left and right, the user can perform a rollover exercise. Therefore, in the case of a sick person or an elderly person who is lying on the bed for a long period of time, it is possible to prevent pressure ulcer (bed swelling) by performing the above-described turning exercise at a slow speed.

In the above embodiment, the output shaft of the two-axis motor is
Although the drive shaft for rotating the turntable was connected to the drive shaft by a coupling, if the drive shaft is connected using an electromagnetic clutch instead of the coupling, the electromagnetic clutch can be remotely operated to drive the drive shaft with respect to the output shaft. Since the connection angle in the rotation direction can be changed, the swing phase of each of the pair of left and right divided pieces can be controlled thereby.

[0033]

As described above, according to the present invention, the floor plate is constituted by a plurality of divided pieces, and the rotary motion of the drive shaft is converted into the up-down motion and transmitted to these divided pieces, thereby causing the floor plate to swing. The stroke of the vertical movement and the amount of the left and right rows
The swinging phase of the split piece can be changed.

[0034] Therefore, by swinging and driving each of the divided pieces, the user lying on the mattress can bend the waist portion of the body, and use the bed device to recover physical strength and maintain health. it can perform movements such as, moreover vertical motion of the stroke - when changing the click, changing the amplitude of oscillation of the divided pieces, since it is possible to vary the intensity of the exercise given to the user, the user, such as the physical condition Exercise of the appropriate intensity can be performed. In addition, change the swing phase of the left and right split pieces
If this happens, the user's body will swing right and left,
Old people who have been lying for a long time
It can prevent bedsores in patients and the sick.
