JP-A-11-113974

In the bed swinging device described in Patent Document 1 and the bed to which this device is attached, an upper liner is joined to the bottom surface of the plate, a lower liner is joined to the upper surface of each base member, and both liners are mutually attached. By contacting, the plate can smoothly reciprocate on the base member.
However, in the bed swinging device described in Patent Document 1, swinging in a direction crossing the swinging direction is such that the plate is fitted into a base member having a U-shaped cross section, and the side surface of the plate and the inner wall surface of the base member Therefore, a thick plate is required.

  Therefore, since a plate having a large plate thickness is heavy, a driving unit having a large driving force is required to swing the thick plate. In addition, the size of the apparatus is increased.

  SUMMARY OF THE INVENTION An object of the present invention is to provide a human body rocking device capable of downsizing a rocking mechanism while restricting rocking that deviates laterally from the rocking direction.

  The human body oscillating device according to the present invention includes a fixed part arranged at an installation location, an oscillated part arranged on the fixed part and supporting the whole body or a part of the human body, and the oscillated part. A rocking drive unit that reciprocates, and a sliding mechanism that slides the rocked part with respect to the fixed part, wherein the sliding mechanism has a bottom surface of the rocked part with respect to an upper surface of the fixed part. A first sliding mechanism portion that slides; and a second sliding mechanism portion that is in contact with the oscillated portion and that is formed with a vertical plane parallel to the oscillating direction that regulates lateral deviation from the oscillating direction. Features.

  According to the human body rocking device of the present invention, the reciprocating movement of the rocked portion in the rocking direction can be smoothly performed by the first sliding mechanism. Since the first sliding mechanism only has to swing the swung portion along the swing direction, the thickness does not have to be large. In addition, even if the oscillated portion tends to deviate from the oscillating direction, the oscillating portion contacts and regulates the vertical surface of the second sliding mechanism parallel to the oscillating direction, thereby preventing the oscillating portion from being laterally displaced. The reciprocating movement can be performed stably. The vertical surface of the second sliding mechanism only needs to be in contact with the oscillating portion when the oscillating portion is laterally displaced and the lateral displacement of the oscillating portion can be regulated, so that the height does not have to be high.

The first sliding mechanism is provided on one or both of the upper surface of the fixed portion and the bottom surface of the oscillated portion, and the second sliding mechanism is formed on the fixed portion, A first sliding member having a vertical surface and a horizontal surface facing downward; a first opposed surface formed on the oscillating portion and sliding on the vertical surface of the first sliding member; And a second sliding member having a second facing surface that slides on the horizontal surface of the one sliding member.
Since either the fixed part or the oscillated part moves so as to slide on the first sliding mechanism part attached to the attachment surface, it can move smoothly in the oscillating direction. Further, since the vertical surface of the first sliding member and the first opposing surface of the second sliding member slide in the second sliding mechanism portion, the lateral displacement in the horizontal direction can be restricted. Further, since the horizontal surface of the first sliding member and the second facing surface of the second sliding member slide in the second sliding mechanism portion, vertical displacement in the vertical direction can be restricted.

  The first sliding mechanism may include a base plate disposed on the mounting surface, and a low friction member fixed to the base plate and having a lower friction coefficient than the mounting surface. Even if there is a difference in height on the mounting surface, it can be adjusted by the thickness of the base plate, so that the low friction member can be installed horizontally.

  The first sliding member is formed by arranging a quadrangular prism-shaped sliding block material having the vertical surface and the horizontal surface arranged along a swinging direction in the fixed portion, and the second sliding member The first facing surface is fixed to the oscillating portion, and the second facing surface is formed to project horizontally from the first facing surface toward the lower side of the sliding block member. be able to.

  The first sliding mechanism portion may be formed by a plurality of low friction members arranged in a direction orthogonal to the swing direction and with a gap. By providing a gap between the low friction members, this gap can be used as a heat dissipation space when the low friction member is overheated, and it can be used as a discharge space for wear powder generated by sliding.

  The fixed portion includes a leg portion standing at an installation location and a fixed side frame supported by the leg portion, and the swingable portion includes a swing side frame that supports the human body that receives the swing, The sliding mechanism may be provided between the fixed portion and the oscillated portion. Since the sliding mechanism is provided between the fixed side frame provided with the leg portion and the swing side frame that supports the human body that receives the swing, the swing side frame swings on the leg portion. Therefore, the rocking side frame can be rocked stably rather than rocking the whole including the leg portion.

  The swing drive unit includes a motor as a drive source, and includes a control unit that controls reciprocation of the swing drive unit. The control unit detects when overcurrent to the motor is detected. It is possible to have a function of stopping the energization of the. An overload to the motor can be prevented by detecting an overcurrent flowing through the motor such as when a heavy user puts on the oscillated portion and stopping the energization of the motor.

The oscillating portion includes a oscillating frame that reciprocates by the oscillating drive portion, a mat portion that reciprocates together with the oscillating frame, and a back raising drive portion that raises the mat portion back, A back-up sensor for detecting the degree of inclination of the mat part and a control part for controlling reciprocation of the swing drive part, wherein the back-up sensor has detected a predetermined degree of inclination; By this notification, it is possible to provide a function of decelerating or stopping the reciprocating movement by the swing drive unit.
When the mat is raised, the upper body of the user becomes unstable. The back-up sensor detects a predetermined inclination angle and notifies the control unit, so that the control unit decelerates or stops the reciprocating movement by the swinging drive unit, so that the user can be prevented from going outside. .

  A knee-raising drive unit that pushes up the knee portion of the mat portion may be provided. If you swing it when you raise it, the user may go out, but the knee-raising drive pushes up the knee part of the mat to improve the stability of the rocking user. be able to.

  An elevating drive unit for elevating and lowering the oscillating unit; an elevating sensor for detecting the elevating height of the oscillated unit; and a control unit for controlling reciprocating movement in the oscillating drive unit. The unit may have a function of decelerating or stopping the reciprocating movement by the swing drive unit when the elevating sensor detects a predetermined height. When the lifting sensor detects that the swung part has reached a predetermined height and notifies the control part, the control part decelerates or stops the reciprocating movement by the swinging drive part. Can be prevented.

  When cushioning members are provided at both ends in the swinging direction of the swung portion, the user is prevented from entering the gap between the swung portion and the wall surface of the installation location. Can do. Even if the user enters the gap, the cushioning member hits the user and the impact can be mitigated.

The rocked portion includes a fence that can be selected between an open state and a closed state, a fence sensor that detects the open state of the fence, and a control unit that controls reciprocation of the rocking drive unit. The control unit has a function of stopping the reciprocating movement when the fence sensor detects an open state of the fence when the oscillating part is reciprocated by the oscillating drive part. can do.
When the swinging part is swinging, if the user changes the fence from the closed state to the open state, the fence sensor detects the open state and notifies the control unit. Since the reciprocation is stopped, the user can be prevented from going out.

  When the fence is formed so that an operator's foot can be inserted into the gap from the lower end when the fence is open to the installation surface of the installation location and pass under the fence, Since the assistant who operates the user who is placed on the moving part can put the foot part below the fence, it can be positioned close to the human body rocking device of the present invention.

  According to the present invention, since the first sliding mechanism only needs to swing the oscillating portion along the oscillating direction, the thickness is not required, and the second sliding mechanism has a lateral displacement of the oscillating portion due to the vertical surface. The height is not necessary as long as it can be regulated. Therefore, according to the present invention, the swing mechanism can be downsized while restricting the swing that deviates laterally from the swing direction.

A human body rocking device according to an embodiment of the present invention will be described with reference to the drawings.
1 and 2 is a swing bed for adults on which a user (human body) lies and massages, rehabilitates, or induces sleep by swinging. .
The human body oscillating device 10 includes a fixed portion 11 disposed at an installation location, a oscillated portion 12 disposed on the fixed portion 11, and an oscillating drive portion 13 that reciprocates the oscillated portion 12. A sliding mechanism 14 that slides the oscillating portion 12 with respect to the fixed portion, a control portion 15 that controls each driving portion, various sensors, and an operation panel 16 (see FIG. 5) are provided.

The fixed part 11 includes four wheels 111 for traveling in the installation place, four level foot type legs 112 standing at the installation place, and a fixed side frame 113 supported by the leg parts 112. Yes.
The wheels 111 facilitate the movement of the human body rocking device 10, and are attached to the lower portions of the corners of the fixed side frame 113.
The leg 112 makes the human body rocking device 10 horizontal and corresponds to the wheel 111 so that the human body rocking device 10 does not move by the wheel 111 when the user is placed or rocks. Attached.
The fixed side frame 113 is a metal frame formed in a rectangular shape in plan view. The swing drive unit 13 is attached to the fixed side frame 113.

The oscillating portion 12 includes an oscillating side frame 121 that supports a user who receives oscillating motion, and a mat portion 122 installed on the oscillating side frame 121.
The swing side frame 121 includes a frame main body 1211 formed in a rectangular shape in plan view, a reinforcing member 1212 for reinforcing the frame main body 1211, and a fixing plate 1213 for fixing the mat portion 122 to the swing side frame 121. And a metal frame.

The frame body 1211 is formed so that the length in the length direction (height direction) F <b> 1 is the same as that of the fixed side frame 113.
The length of the frame body 1211 in the width direction F <b> 2 is shorter than the fixed side frame 113. The frame main body 1211 is formed so that the inner side surface along the length direction F1 and the inner side surface of the fixed side frame 113 are at the same position. Further, the width of the tube member forming the frame main body 1211 is smaller than the tube member forming the fixed side frame 113. Therefore, when the frame main body 1211 is arranged on the upper surface 113a of the fixed side frame 113, a space for mounting a second sliding mechanism portion described later on the upper surface 113a of the fixed side frame 113 can be secured.
The reinforcing member 1212 extends in the width direction F2 at the center in the length direction F1 of the frame body 1211 and crosses the width direction F2 of the frame body 1211.
The fixed plate 1213 is a metal plate that is attached to the side surface 1211a along the length direction F1 of the frame body 1211 and protrudes upward.

  The mat portion 122 includes a metal bed frame 1221 formed in a rectangular shape in plan view, and a mattress 1222 having cushioning properties, like the swing side frame 121.

The swing drive unit 13 includes a support member 131 for attaching each member of the swing drive unit 13 and the control unit 15 to the fixed side frame 113, and a motor 132 serving as a drive source for swinging the swinged unit 12. And a crank mechanism 133 that converts the rotation of the rotating shaft of the motor 132 into a linear reciprocating movement.
The support member 131 is formed so as to extend in the width direction F2 near one side (for example, the leg side) in the length direction F1 of the fixed side frame 113 and cross the width direction F2 of the fixed side frame 113. .
In this embodiment, the motor 132 uses an AC motor. For example, a motor with an output of 200 W can be used.
As shown in FIG. 3, the crank mechanism 133 includes a bevel gear (not shown) that transmits the horizontal axis (drive shaft) of the motor 132 to the vertical shaft 1331, and a crank disk 1332 that rotates about the vertical shaft 1331. One end 1333a is connected to an eccentric position of the crank disk 1332, and a swing arm 1333 is connected to one end of the swing side frame 121 in the longitudinal direction F1 and the other end 1333b. Yes.

As shown in FIGS. 1 and 2, the sliding mechanism 14 is provided at least in four places, two on each side along the length direction F <b> 1 of the fixed side frame 113 and the swing side frame 121. .
As shown in FIG. 4A and FIG. 4B, the sliding mechanism 14 has a bottom surface 121a of the swing side frame 121 of the swinged portion 12 with respect to the top surface 113a of the fixed side frame 113 of the fixed portion 11. A first sliding mechanism 141 that slides, a second sliding mechanism 142 that regulates movement of the oscillated portion 12 in a direction other than the oscillating direction F3, and a guide plate 143 (see FIG. 2) are provided. Yes.

The first sliding mechanism 141 can be provided on either one or both of the upper surface 113a of the fixed side frame 113 or the bottom surface 121a of the swing side frame 121, but in the present embodiment, the fixed side frame 113 is provided. The upper surface 113a is disposed as the mounting surface S1.
The first sliding mechanism 141 includes a base plate 1411 disposed on the mounting surface S1 and a low friction member 1412 attached to the base plate 1411 and having a lower friction coefficient than the bottom surface 121a of the swing side frame 121.

The base plate 1411 is a rectangular metal plate. The base plate 1411 is a spacer whose thickness is adjusted in order to ensure the level of the upper surface 113a of the fixed side frame 113.
The low friction member 1412 is a tape-like member formed in substantially the same shape as the base plate 1411. The low friction member 1412 can be made of nylon resin or fluorine resin. For example, as the low friction member 1412, a tape-like polyslider (registered trademark) or nitoflon (registered trademark) can be used. The low-friction member 1412 may be a granular / liquid slider, plate-like polyacetal / polyamide / polytetrafluoroethylene / polyphenylene sulfide, or the like.

The second sliding mechanism 142 is provided on the outer surface of the fixed side frame 113 and the swing side frame 121. The second sliding mechanism part 142 includes a first sliding member 1421 formed on the fixed side frame 113 of the fixed part 11, and a second sliding member 1422 formed on the swing side frame 121 of the swinged part 12. It has.
The first sliding member 1421 is attached to the side surface 113b along the length direction F1 of the fixed side frame 113, and has a fixed plate 1421a protruding upward, and a quadrangular prism-like shape attached to the inside of the fixed plate 1421a. And a sliding block member 1421b.

  Since the sliding block member 1421b is formed in a quadrangular prism shape and disposed along the length direction F1 (swinging direction F3), the surface facing the swinging side frame 121 is parallel to the swinging direction F3. The surface which becomes the vertical surface 1421s1 and faces the upper surface 113a of the fixed side frame 113 becomes the horizontal surface 1421s2 which faces downward.

The second sliding member 1422 has a first opposing surface 1422s1 that slides on the vertical surface 1421s1 of the sliding block member 1421b in the first sliding member 1421, and the sliding block member 1421b in the first sliding member 1421. This is an L-shaped metal fitting having a second facing surface 1422s2 that slides on the horizontal surface 1421s2.
In the second sliding member 1422, the first facing surface 1422 s 1 is fixed to the side surface along the length direction F 1 of the swing side frame 121 of the swingable portion 12, and the second facing surface 1422 s 2 is fixed to the first facing surface 1422 s 1. To the bottom of the sliding block member 1421b and projecting in the horizontal direction.

The guide plate 143 is a plate-like member provided on the inner side surface of the fixed side frame 113 and formed so as to protrude from the inner side surface of the swing side frame 121.
Similar to the sliding mechanism 14, the guide plates 143 are provided at least at four locations, two on each side of the fixed frame 113. The sheet-like low friction member employed in the first sliding mechanism 141 is attached to the surface of the guide plate 143 facing the inner surface of the swing side frame 121.

  As shown in FIGS. 1 and 2, the control unit 15 is mounted on the support member 131 of the swing drive unit 13. The control unit 15 adjusts the swing by controlling the motor 132 of the swing drive unit 13 according to an instruction from the operation panel 16 shown in FIG. 5 and monitors the load (current) to the motor 132. It has.

The operation and use state of the human body rocking device 10 according to the embodiment of the present invention configured as described above will be described with reference to the drawings.
The user operates the operation panel 16 shown in FIG. 5 to instruct the human body rocking device 10 to rock.
When an instruction to start swing is notified from the operation panel 16 to the control unit, the control unit energizes the motor 132 of the swing drive unit 13.
When energization of the motor 132 is started, the motor 132 rotates. As shown in FIG. 3, when the motor 132 rotates, the vertical shaft 1331 of the crank mechanism unit 133 rotates, and the crank disk 1332 rotates.
The rotation of the crank disk 1332 causes the one end 1333a of the swing arm 1333 that is rotatably connected to the eccentric position of the crank disk 1332 to move circularly, so that the other end 1333b of the swing arm 1333 reciprocates linearly.
As the other end 1333b of the swing arm 1333 reciprocates linearly, the swing side frame 121 connected to the other end 1333b of the swing arm 1333 reciprocates in the length direction F1.

At this time, as shown in FIGS. 4A and 4B, the bottom surface 121 a of the swing side frame 121 of the swingable portion 12 is provided on the top surface 113 a of the fixed side frame 113 of the fixed portion 11. Since it slides on the low friction member 1412 of the 1st sliding mechanism part 141, it can reciprocate smoothly.
Even if the upper surface 113a of the fixed side frame 113 has a convex or concave bend, the level of the swinging side frame 121 mounted on the upper surface 113a may vary depending on the thickness of the base plate 1411 of the first sliding mechanism 141. Therefore, even if the low friction member 1412 is a tape-like thin member, the swing side frame 121 can be stably swung.

  The oscillating drive unit 13 linearly reciprocates the oscillated portion 12. However, when the oscillated portion 12 oscillates on the fixed portion 11, the first sliding mechanism portion 141 alone oscillates. There is a concern that the part 12 may be laterally displaced in the horizontal direction or vertically displaced in the vertical direction. However, the second sliding mechanism 142 is restricted from moving in directions other than the swing direction F3.

  For example, when the oscillated portion 12 attempts to move in a direction F4 (see FIG. 4B) that horizontally intersects the oscillating direction F3, the vertical surface 1421s1 of the sliding block member 1421b in the first sliding member 1421 is obtained. Is formed in parallel with the swinging direction F3, and the first facing surface 1422s1 of the second sliding member 1422 slides on the vertical surface 1421s1, and the second sliding is left and right with respect to the swinging direction F3. Since the mechanism part 142 is provided, it is possible to prevent the oscillated part 12 from shifting in the width direction F2 with respect to the length direction F1.

  Further, when the oscillated portion 12 tries to move in a direction F5 (see FIG. 4B) that intersects the oscillating direction F3 vertically, the horizontal surface 1421s2 of the sliding block member 1421b is parallel to the oscillating direction F3. Since the second facing surface 1422s2 of the second sliding member 1422 slides on the horizontal surface 1421s2, the oscillating portion 12 is prevented from shifting in the vertical direction. Can do.

Thus, since the 1st sliding mechanism 141 should just rock | fluctuate the to-be-oscillated part 12 along the rocking | fluctuation direction F1, thickness does not need to be thick. Accordingly, the first sliding mechanism 141 can be formed with a low friction member 1412 or the like. Further, the second sliding mechanism 142 only needs to be in contact with the oscillated portion 12 when it is laterally displaced and to restrict further lateral displacement. Accordingly, the second sliding mechanism 142 can be formed by a sliding block member 1421b having a vertical surface 1421s1.
Therefore, the sliding mechanism 14 of the human body rocking device 10 can be reduced in size while restricting the rocking that deviates laterally from the rocking direction F3.

  Further, the guide plate 143 contacts the inner surface of the swing side frame 121 together with the second slide mechanism 142 that controls the lateral displacement, and the lateral displacement of the pivoted portion 12 is regulated. Disperses the stress caused by excessive lateral displacement. Therefore, durability can be improved and safety can be improved.

In the bed swinging device described in Patent Document 1, the drive unit is located near the floor surface, and the entire bed including the leg unit is swung. However, if the bottom on which the mattress is placed is swung through the leg portion having a relatively low strength, the bottom portion and the mattress with heavy weight cannot follow the swing on the leg portion because the leg portion is bent. There is a possibility of reciprocating movements.
Therefore, in the bed swing device described in Patent Document 1, a time shift of the swing timing is likely to occur between the drive unit and the bottom, and twist is also likely to occur. This appears as an unnecessary sliding contact force on the regulating portion in the swinging direction of the slider, which may cause uneven wear on the slider.

  According to the human body rocking device 10 according to the first embodiment, the sliding mechanism 14 is provided between the stationary frame 113 provided with the legs 112 and the rocking frame 121. Accordingly, since the leg portion 112 does not swing while firmly standing on the floor (installation location), the oscillated portion 12 can be stably oscillated with respect to the fixed portion 11, so that durability is ensured. It can be set as the rocking device 10 for human bodies with high.

When the control unit 15 shown in FIG. 5 instructs the motor 132 of the swing drive unit 13 to start, the weight of the user is heavy or a plurality of users are placed on the mat unit 122 (see FIG. 1), and the total May be heavy. The control unit 15 monitors the current flowing through the motor 132. When an overcurrent is detected, the control unit 15 stops energization of the motor 132 and stops starting.
Also, during swinging, another user may suddenly rest on the mat portion 122 and an overcurrent may flow through the motor 132. Even in such a case, the control unit 15 stops energization of the motor 132 and stops swinging.
As described above, the control unit 15 can prevent the motor 132 from being damaged by detecting the overcurrent to the motor 132 and preventing overload.

In the first embodiment, the second sliding mechanism 142 is provided on the outer surface of the fixed side frame 113 and the swing side frame 121, and the guide plate 143 is provided on the inner side surface of the fixed side frame 113. The second sliding mechanism 142 is provided on the inner side of the fixed side frame 113 and the swing side frame 121, and the guide plate 143 is provided on the outer side of the fixed side frame 113. Also good.
If the second sliding mechanism 142 is provided on the inner surface of the fixed frame 113 and the swinging frame 121, it will directly hit the second sliding mechanism 142 when an object collides from the outside. Can be prevented.

Next, a modification of the human body rocking device according to the second embodiment of the present invention will be described with reference to the drawings. In FIGS. 6A and 6B, the same components as those in FIG.
In the modification of the human body rocking device shown in FIG. 6, the first sliding mechanism 141A includes two low friction members (a first low friction member 1412a and a second low friction member 1412b).
The first low friction member 1412a is provided on the upper surface 113a (base plate 1411 which is a metal plate) of the fixed side frame 113. The second low friction member 1412 b is provided on the bottom surface 121 a of the swing side frame 121.
The first low-friction member 1412a and the second low-friction member 1412b can be the same as the low-friction member 1412 (see FIG. 4), but it is desirable to employ a combination of different materials. These low friction members have wear resistance and self-lubricating properties and can be selected from those having a low friction coefficient.

In the first sliding mechanism portions 141 and 141A shown in FIG. 4 (B), FIG. 6 (A), and FIG. 6 (B), the tape-shaped low friction member 1412 or the first low friction member 1412a and the second One low friction member 1412b is attached along the swinging direction F3, but a plurality of low friction members 1412b are arranged along the direction orthogonal to the swinging direction F3 so as to be arranged with a gap S therebetween. May be.
For example, as shown in FIG. 7, three tape-shaped low friction members (first low friction member 1412A, second low friction member 1412A, second low friction member 1412A, A friction member 1412B) is affixed.
The first low friction member 1412A can be made of nitoflon on both sides and a polyslider on the center. The second low friction member 1412B can be made of polysliders on both sides and nitoflon on the center.
