Description

  The present invention relates to a bed apparatus capable of changing a height by driving a bed frame in the vertical direction.

  For example, a bed device for nursing care used by an elderly person or a user with a physical disability has a bed body. The bed main body is provided with a bed frame that can be moved up and down by a drive mechanism driven by a drive source. A floor plate is supported on the bed frame, and a mattress is placed on the upper surface of the floor plate.

  Ordinarily, elderly people and users with physical disabilities are supine on the mattress, and when the user receives care from a caregiver or sees a doctor, it is easy to do the work. The height of the bed frame is changed.

  On the other hand, when the user goes to bed, the bed frame is used with a sufficiently low level so that the user can fall over and reduce the impact when the user falls from the mattress to the floor. Is done.

  By the way, when the bed frame is lowered to be used sufficiently low, a user or a caregiver descending from the mattress may sandwich his / her foot between the bottom surface of the bed frame and the floor surface, There was a risk that an article placed nearby would get caught and pinched.

  That is, a bed apparatus having a drive source that operates a drive mechanism for raising and lowering the bed frame is provided with a remote controller for driving the drive source. The remote controller is provided with an up switch for raising the bed frame and a down switch for lowering the bed frame.

  When the bed frame is lowered, the bed switch at a height of 600 mm from the floor, for example, is lowered at a time to a lower limit position of 250 mm, for example, by continuously pressing the lower switch. I try to let them.

  Therefore, before the caregiver or user near the bed controller or the caregiver or the user notices or retreats even if it notices, the bed frame descends to the lower limit position. There is a possibility that a user or the like may pinch his / her foot or an article placed near the bed apparatus may get caught.

  Therefore, even when the lower switch of the remote controller is continuously operated to lower the bed frame, when the bed frame is lowered to an intermediate position between the upper limit position and the lower limit position, the lowering operation is temporarily stopped at that position. Thereafter, the bed frame is lowered from the intermediate position to the lower limit position by releasing the push-down switch and then pressing it again. Accordingly, a bed apparatus has been developed that improves safety when the bed frame is lowered.

  However, if the same switch is pressed again to lower the bed frame to the lowest position, the operator may mechanically continuously operate the switch.

  That is, when the bed frame is lowered from the height of the intermediate position to the height of the lower limit position, the operator can continuously perform the re-pressing operation at hand by momentarily releasing the finger from the lowering switch. As a result, the safety confirmation of the surroundings may be neglected.

  As a result, if there are users or caregivers in addition to the operator near the bed device, the user or caregiver may pinch his / her foot between the bed frame and the floor surface, or remove items near the bed device. There was a risk of pinching.

  Therefore, in order to prevent the bed frame from being continuously lowered from the height of the intermediate position to the height of the lower limit position, the remote controller includes a first for lowering the bed frame from the upper limit position to the intermediate position. And a second lowering switch for lowering the bed frame from the intermediate position to the lower limit position at a place other than the remote controller.

  Accordingly, the operator operates the first lowering switch to lower the bed frame from the upper limit position to the intermediate position, and then moves to the position where the second lowering switch is provided, where the second lowering switch is provided. A bed apparatus has been developed in which the bed frame can be lowered from the intermediate position to the lower limit position by operating the switch.

  Accordingly, after the operator operates the first lowering switch, the operator cannot continuously operate the second lowering switch, and a time difference occurs until the second lowering switch is operated. Safety can be improved during this period, for example, by confirming safety.

Japanese Patent No. 4141233 Japanese Patent No. 5707371

  By the way, when the first lowering switch is provided in the remote controller and the second lowering switch is provided in a place different from the remote controller, the operator lowers the bed frame from the upper limit position to the intermediate position. After that, it is necessary to move to the place where the second lowering switch is provided, and to operate the second lowering switch to lower the bed frame to the lower limit position.

  Therefore, when lowering the bed frame to the lower limit position, the operator must move from the position of the first lowering switch to the position of the second lowering switch, which takes time and labor. May be greatly reduced.

  For example, if the operator needs to move to the position of the second lowering switch while taking care such as supporting a physically handicapped user with one hand, the movement is not easy. There is also.

  Further, if the first lowering switch and the second lowering switch are provided at different locations, it may be necessary to secure an installation place for the second lowering switch, and the structure therefor is It may be complicated.

  The present invention provides a bed apparatus that can improve both safety and operability when the bed frame is lowered in two stages from an upper limit position to an intermediate position and from an intermediate position to a lower limit position. Is to provide.

The present invention includes a bed frame provided so as to be drivable in the up and down direction
Driving means for driving the bed frame in the vertical direction and the downward direction between the upper limit position and the lower limit position;
Control means for controlling the raising / lowering drive of the bed frame by the drive means;
An operation control unit for controlling driving in the upward and downward directions of the bed frame;
In the operation control unit,
An ascending operation part for driving the bed frame in the ascending direction;
A first lowering operation unit for driving the bed frame from the upper limit position to an intermediate position above the lower limit position;
A second descent separate from the first descent operation unit that drives the bed frame driven in the descent direction to the intermediate position by the operation of the first descent operation unit to the lower limit position in the descent direction. The bed device is provided with an operation unit.

  According to the present invention, the operator operates the first lowering operation unit to lower the bed frame from the upper limit position to the intermediate position, and then moves the second lower operation unit to lower the bed frame from the intermediate position to the lower limit position. In operating the second lowering operation unit, the finger must be moved from the first lowering operation unit to the second lowering operation unit. That is, the operation of the second lowering operation unit is prevented from being inadvertently performed continuously with the operation of the first lowering operation unit.

For this reason, a time difference is generated when the second lowering operation unit is operated from the first lowering operation unit, and thus it is possible to improve safety during that time.
Moreover, since the first lowering operation unit and the second lowering operation unit are provided in one operation control unit, workability is greatly improved as in the case where these are provided in completely different places. It can be prevented from lowering.

A roller 13e is provided at the other end of each arm 12d, 13d . The roller 12e of the first arm 12d is in rolling contact with the lower surface of the back raising floor portion 11a, and the roller 13e of the second arm 13d is in contact with the lower surface of the first leg raising floor portion 11d.

  When the back raising drive source 12 and the leg raising drive source 13 are operated to drive the drive sources 12 and 13 in the forward direction, the rotary shafts 12b and 13b are rotationally driven via the links 12c and 13c. . As a result, the first arm 12d and the second arm 13d are driven in the raising direction, and as a result, the back raising floor portion 11a and the first leg raising floor portion 11d are moved to the tips of the arms 12d and 13d. Are raised by being pressed by rollers 12e and 13e.

Incidentally, when to raising the first leg raised floor portion 11d, the second leg on up floor portion 11e is interlocked to its elevation. Thereby, the first leg on up floor portion 11d and the second leg on up floor portion 11e is bent to shape to substantially.

It is provided side by side.

Further, a second lowering switch 29 as a second lowering operation unit is provided above the back raising switch 24 and the back lowering switch 25 on the operation surface 21a. That is, the second lowering switch 29 is disposed at a position that is not adjacent to the first lowering switch 23 in the vertical direction and the horizontal direction.
In this embodiment, each switch provided on the operation surface 21a is a push button type, but a touch type switch may be used instead of the push button type.

  The second lowering switch 29 is provided with another position of the operation surface 21a, for example, a height position where the leg raising switch 26 and the leg lowering switch 27 are provided, and a back raising switch 24 and a back lowering switch 25. In other words, it may be provided at a position that is not adjacent to the first lowering switch 23 in the vertical direction and the horizontal direction.

  On the operation surface 21a of the remote controller 21, on the side of the second lowering switch 29, a slide type lock switch 30 as a lock means is provided side by side. The lock switch 30 is slidable between a lock position and a release position for releasing the lock.

  The second lowering switch 29 is mechanically locked when the lock switch 30 is in the locked position shown in FIG. 3, and is released by sliding in the direction indicated by the arrow from the locked position. If it is in the position, it can be pressed.

  In addition to the lock switch 30, the back of the remote controller 21 can be electrically turned on / off by pressing the switch of the remote controller 21, for example, by pressing it with the tip of a ballpoint pen. A pressing switch (not shown) for locking the operation is provided. Further, a hook 28 is provided on the upper portion of the remote controller 21.

  The hook 28 can detachably attach the remote controller 21 to the headboard body 17 or side rails (not shown) provided on both sides of the bed frame 5.

  In this embodiment, the second lowering switch 29 is mechanically locked by using a slide-type lock switch 30 as a lock mechanism, but other mechanical methods include a dial type and the above It may be a push button type that is provided so as not to protrude from the surface of the remote controller 21 and is pressed using a thin stick such as a pin or a ball-point pen, and further a push button type structure that is electrically locked. It may be. In that case, the second lowering switch 29 is double-locked by the pressing switch.

Furthermore, various locking mechanisms described above the remote controller may be provided on an operation surface 21a other than the side or back of the 21, or is not intended to be limited where provided.

  A control device 31 constituting control means indicated by a chain line in FIGS. 1 and 2 is provided near the one end side in the width direction at the center portion in the longitudinal direction of the lower surface of the bed frame 5. A relay cord 32 that is electrically connected to a control device (not shown) provided therein is led out from the control device 31.

  The relay cord 32 is branched into two branch lines 32a and 32b by a distributor 33. One branch line 32a is led from one end in the width direction of the bed frame 5 to the headboard body 17 side, and the other branch line 32b is the other end in the width direction. To the headboard body 17 side. A male terminal portion 34a is connected to the tip of each branch line 32a, 32b.

  The remote controller 21 is detachably connected to the male terminal portion 34a provided on the branch lines 32a and 32b of the relay cord 32. That is, the connection cord 36 is led out from the remote controller 21, and a female-side terminal portion 34 b is provided at the tip of the connection cord 36.

  And this female side terminal part 34b is selectively connected to either one of the male side terminal parts 34a provided in the two branch lines 32a and 32b. As a result, as shown in FIG. 4, the remote controller 21 operates the drive sources 8, 12, 13 through the control device 31 to move the bed frame 5 up and down, or to raise the floor 11a for raising the back. The first and second leg raising floor portions 11d and 11e can be driven up and down.

  The raising / lowering drive source 8 for raising / lowering the bed frame 5 is operated by operating the raising switch 22, the first lowering switch 23, and the second lowering switch 29 provided in the remote controller 21. It is driven via 31.

  That is, as shown in FIG. 4, when the bed frame 5 is driven to the upper limit position that is the operation limit in the upward direction, the lifting drive source 8 includes an upper limit switch 44a for detecting that. There is provided an intermediate switch 44b for detecting when the intermediate position is lowered to the middle position and a lower limit switch 44c for detecting this when driven from the intermediate position to the lower limit position which is the operation limit in the downward direction. It has been. Here, as shown in FIG. 6, the upper limit position is UH, the intermediate position is MH, and the lower limit position is LH.

  In this embodiment, the switches 44a, 44b, and 44c are provided so as to be sequentially operated in accordance with the amount of movement of the drive shaft 8a that is advanced and retracted by the elevating drive source 8. The amount of movement of the drive shaft 8a corresponds to the height change of the bed frame 5.

  When the raising switch 22 of the remote controller 21 is continuously pressed and the bed frame 5 is driven to the upper limit position UH, the upper limit switch 44a is activated and the elevating drive source 8 is stopped. That is, the rising of the bed frame 5 is stopped. In this embodiment, the upper limit position UH of the bed frame 5 is set to 600 mm from the floor surface.

  In order to lower the bed frame 5 at the upper limit position UH, the first lowering switch 23 provided in the remote controller 21 is operated. Thereby, the bed frame 5 is lowered from the upper limit position UH.

  When the bed frame 5 is lowered from the upper limit position UH to the intermediate position MH and the intermediate switch 44b is operated, the lowering of the bed frame 5 is stopped. In this embodiment, the intermediate position MH of the bed frame 5 is set to 300 mm from the floor surface. The height 300 mm of the intermediate position MH is a height that does not get caught even if there is a caregiver's or user's foot between the bed frame 5 and the floor surface. When the bed frame 5 is further lowered, It is a dimension that increases the possibility that the feet of the caregiver or the user will be sandwiched between the bed frame 5 and the floor surface.

  When the bed frame 5 is lowered from the intermediate position MH to the lower limit position LH in the downward direction, the pressing operation of the first lowering switch 23 of the remote controller 21 is released, and then the remote controller 21 is provided with the remote controller 21. The second lowering switch 29 different from the first lowering switch 23 is pressed.

  Before pressing the second lowering switch 29, the second lowering switch by the lock switch 30 can be operated by sliding the locking switch 30 to the release position and pressing the second lowering switch 29. 29 is released from the locked state.

  When the second lowering switch 29 is pressed, the bed frame 5 is driven in the lowering direction from the intermediate position MH. When the bed frame 5 is lowered to the lower limit position LH, the lower limit switch 44c is operated to stop the lowering of the bed frame 5. In this embodiment, the lower limit position LH of the bed frame 5 is set to a height of 250 mm from the floor surface.

  As shown in FIG. 4, the control device 31 is connected with a sound output device 50 as a notification means. In the audio output device 50, the control device 31 indicates that the operation state of the upper limit switch 44a has been released by the bed frame 5 being driven in the downward direction by the elevating drive source 8 from the upper limit position UH. When recognized, it informs that the bed frame 5 is lowered by, for example, a sound of [lowering]. This sound is stopped when the bed frame 5 is lowered to the intermediate position MH and the intermediate switch 44b is operated.

  Further, when the control unit 31 recognizes that the sound output device 50 is driven further downward from the intermediate position MH and the operation state of the intermediate switch 44b is released, In the same manner as described above, the fact that the bed frame 5 is lowered is notified by, for example, a sound of [lowering]. The sound is stopped when the control device 31 recognizes that the bed frame 5 is lowered from the intermediate position MH to the lower limit position LH and the lower limit switch 44c is activated.

  That is, when the bed frame 5 is driven in the descending direction, a sound is output from the sound output device 50 to call attention, so that the bed frame 5 hits or is pinched. Is prevented and safety is improved.

  Note that the notification means is not limited to the sound output device 50 that outputs sound, but the bed frame 5 is notified by flashing a lamp provided on the bed frame 5 or the like, or by both flashing and sound of the lamp. It may be informed that is driven in the downward direction, and the means for notifying is not specified.

  FIG. 5 is a flowchart when the bed frame 5 is lowered from the height of the upper limit position UH to the height of the lower limit position LH through the height of the intermediate position MH. First, when the descending operation of the bed frame 5 is started, in S1, it is determined whether or not the height of the bed frame 5 is equal to or higher than the intermediate position MH (300 mm). This determination is made based on whether or not the intermediate switch 44b is operating.

  If YES, an operation is performed so that the first lowering switch 23 of the remote controller 21 is turned on. In S2, it is determined whether or not the first lowering switch 23 is on. If it is on, the bed frame 5 is driven in the lowering direction.

  When the bed frame 5 starts to descend, it is determined in S3 whether or not the height has been lowered to the intermediate position MH of 300 mm. This determination is made based on whether or not the intermediate switch 44b is operating.

  When the height of the bed frame 5 is lowered to 300 mm and this is detected by the intermediate switch 44b, the lowering operation of the bed frame 5 is stopped. This lowered state is indicated by a straight line A in FIG.

  When the bed frame 5 is further lowered from the height of the intermediate position MH, after the operation of the first lowering switch 23 of the remote controller 21 is released, the remote controller 21 is connected to the first lowering switch 23. The second lowering switch 29 provided separately is pressed. In S4, it is determined whether or not the second lowering switch 29 is on.

  Prior to pressing the second lowering switch 29, the second lowering switch 29 by the lock switch 30 provided on the side of the second lowering switch 29 on the operation surface 21a of the remote controller 21 is provided. Release the lock status. Thereafter, the second lowering switch 29 is pressed. Thereby, the bed frame 5 further starts to descend from a height of 300 mm at the intermediate position MH.

  In S5, it is determined whether or not the height of the bed frame 5 has reached the lower limit position HL of 250 mm. This determination is made based on whether or not the lower limit switch 44c is operating. When the height of the bed frame 5 becomes 250 mm and this is detected by the lower limit switch 44c, the lowering of the bed frame 5 is stopped. The lowered state of the bed frame 5 at this time is shown by a straight line B in FIG.

  According to the bed apparatus 1 having the above configuration, when the bed frame 5 is lowered from the upper limit position UH to the lower limit position LH via the intermediate position MH, the lowering operation from the upper limit position UH to the intermediate position MH is provided in the remote controller 21. This is done by pressing the first lowering switch 23.

  In order to lower the bed frame 5 from the intermediate position MH to the lower limit position LH after the bed frame 5 is lowered to the intermediate position MH, the operation of the first lowering switch 23 is released, and then the remote controller 21 is connected to the first controller 21. A second lowering switch 29 provided at a position different from the lowering switch 23 is pressed.

  The second lowering switch 29 is provided on the operating surface 21a of the remote controller 21 at a position that is not adjacent to the first lowering switch 23 in the vertical direction and the horizontal direction.

  Therefore, when lowering the bed frame 5 that has been lowered to the intermediate position MH from the intermediate position MH to the lower limit position LH, the operator presses the finger that presses at least the second lower switch 29 among the fingers. The second lowering switch 29 must be pressed by moving it largely upward on the operation surface 21a of the remote controller 21.

  Thereby, after the operator operates the first lowering switch 23, he / she has to move his / her finger relatively large before the second lowering switch 29 is operated. .

  For this reason, the operator confirms safety in the interval, or makes a person around the bed apparatus 1 notice that the bed frame 5 is lowered from the height of the intermediate position MH to the height of the lower limit position LH. It becomes possible to inform.

  As a result, it is possible to prevent the user from being caught by the bed frame 5 where the user, caregiver, or the like descends, so that safety can be improved.

  When the positions of the first lowering switch 23 and the second lowering switch 29 provided on the operation surface 21a of the remote controller 21 are largely separated, the second lowering switch 29 is pressed. In order to operate, it may be necessary to re-grip the remote controller 21.

  In that case, since the interval between the operation of the first lowering switch 23 and the operation of the second lowering switch 29 is further increased, the operator can easily confirm the safety.

  When pressing the second lowering switch 29, the lock switch 30 provided on the side of the second lowering switch 29 is mechanically slid to release the locked state of the second lowering switch 29. Must.

Therefore, after operating the first lowering switch 23, because interval not able to perform the operation of the second opening switch 29 continuously (mechanical) occurs, also improves safety by its Can be achieved.

When lowering the bed frame 5 from a height of the upper limit position UH intermediate position MH to height, when lowering the height between positions MH in及beauty lowermost position LH in the height, that it is an audio output device The voice is output from 50.

  For this reason, the voice notified from the voice output device 50 allows a user or caregiver in the vicinity to recognize that the bed frame 5 of the bed device 1 is driven in the downward direction. Can also improve safety.

  As described above, the first lowering switch 23 and the second lowering switch 29 are provided on the same operation surface 21a of the remote controller 21 at positions where they are not adjacent in the vertical and horizontal directions. After pressing the lowering switch 23, when pressing the second lowering switch 29, the operation becomes discontinuous and a gap occurs, so that safety is improved.

  Therefore, as compared with the conventional case, the first lowering switch 23 is provided in the remote controller 21 and the second lowering switch 29 is provided in a completely different place from the remote controller 21 to ensure safety. The operability when the second lowering switch 29 is pressed after the first lowering switch 23 is pressed can be improved. That is, the operability can be improved as compared with the conventional case while ensuring the safety as in the conventional case.

  In the first embodiment, the bed apparatus has been described in which the bed frame is configured to be movable up and down by the link mechanism with respect to the base frame. However, as in the second embodiment shown in FIG. The present invention can also be applied to a bed apparatus configured to drive the base frame in the vertical direction without using a mechanism.

  That is, in the bed apparatus of the second embodiment, a headboard body 17a is provided at one end in the longitudinal direction of the bed frame 5A, and a footboard body 18a is provided at the other end. At both ends in the width direction of the head board body 17a and the foot board body 18a, hollow support members 51 having lower ends opened are provided. That is, the column members 51 are provided at the four corners of the bed frame 5A.

  Leg members 52 are movably accommodated in the four support members 51. As shown by the arrows, each leg member 52 is driven in a direction protruding from the lower end opening of the column member 51 by an elevating drive source such as a cylinder or a linear motor (not shown) built in the column member 51. ing.

  As in the first embodiment, the raising / lowering drive source (not shown) for driving each leg member 52 is driven from the upper limit position UH to the intermediate position MH by the first lowering switch 23 provided in the remote controller 21. A second lowering switch 42 provided on the remote controller 21 is driven from the intermediate position MH to the lower limit position LH.

  Therefore, even in the bed apparatus having such a configuration, when the bed frame 5A is driven from the intermediate position MH to the lower limit position LH, the second lowering switch 42 provided separately from the first lowering switch 23 is operated. By doing so, it becomes possible to ensure safety.

In the second embodiment, the driving means for driving the leg member 52 may be, for example, a mechanical driving mechanism using a rack and a pinion, and the point is not limited in any way. Absent.

  In each of the above embodiments, the first lowering switch and the second lowering switch are provided in a remote controller as an operation control unit, but the operation control unit is replaced with the remote controller, for example, a head One operation panel may be provided on the board body or the footboard body, and various switches may be provided on the operation panel to serve as an operation control unit.
